Description

The present invention relates to a faucet system having a water outlet section capable of discharging water into a tub body.

The faucet system is provided in correspondence with a basin (e.g., a sink or washbasin), and allows the user to switch water on and off by operating a specified control object (e.g., an operating lever).

The faucet system has a faucet device that includes a faucet main body that is erected on a specified mounting target (e.g., a kitchen sink, a washbasin in a bathroom vanity, or a counter near a tub), and a water outlet that extends from the faucet main body toward a position above the tub and has a water outlet formed at its tip. In addition, a technology is known for faucet systems that allows the water outlet to be rotated horizontally relative to the faucet main body, thereby allowing the position of the water outlet and therefore the water outlet to be changed left and right as seen by the user (see, for example, Patent Document 1, etc.).

JP 2011-144559 A

In the above technology, when adjusting the position of the water outlet (water outlet section), it is necessary to push or pull the side of the tip of the water outlet section with your hand. However, hands can be contaminated with water, foam (e.g., foam from washing your hands, washing your face, washing dishes, etc.), dirt (e.g., dirt that is originally on the hands or dirt from cooking), bacteria, viruses, etc., and with the above technology, these can adhere to the water outlet section when adjusting the position of the water outlet. This can lead to various inconveniences, such as a poor appearance, extra cleaning work, and reduced hygiene.

The present invention was made in consideration of the above circumstances, and its purpose is to provide a faucet system that can more reliably prevent the occurrence of the various inconveniences mentioned above by allowing the water outlet to be rotated without touching the faucet device.

Below, each means suitable for achieving the above objective will be explained item by item. In addition, the specific effects of the corresponding means will be noted as necessary.

Means 1. A faucet system including a faucet device that is attached to a predetermined attachment portion and has a water outlet that discharges water into a water storage portion in a tank body,
A rotating device having an energization operation part that can be operated by energization;
an operation unit for operating the energization operation unit, the operation unit being configured so as to be operable by a user without touching the operation unit with his/her hands;
The faucet device is configured to be rotatable such that the water outlet rotates left and right as seen by a user by operating the operating unit to operate the energizing operating unit,
The attachment target portion defines a front space that is visible to a user and a back space that is invisible or difficult to be visible to a user,
The rotating device is configured so that at least the energizing operation unit is installed in the rear space,
The water faucet device is
A faucet main body part at least a portion of which is disposed in the front space and which is rotatable in response to the operation of the energizing operation part;
a water outlet portion extending from a portion of the faucet main body located in the front space toward an upper position of the water storage portion and having the water outlet at a tip end thereof;
By operating the operating unit to operate the energizing operation unit, the faucet main body rotates, and the water discharge unit and the water discharge port are configured to be rotatable left and right as seen by the user in accordance with the rotation of the faucet main body,
The rotation device includes a longitudinal transmission part that transmits a driving force generated by the operation of the energization operation part from the rear space to the front space through a hole formed through the attachment target part,
This faucet system is characterized in that by operating the operating unit, the driving force caused by the operation of the energizing operating unit is transmitted via the vertical transmission unit to a portion of the faucet main body located in the front space, causing the faucet main body to rotate .

According to the above-mentioned means 1, the water faucet system includes a rotation device having an energized operating part (e.g., a motor, etc.) that can be operated by energizing, and an operating part for operating the energized operating part, which is configured so that the user can operate it without touching it with their hands. By operating the operating part to operate the energized operating part, the water faucet device rotates so that the water outlet rotates left and right as seen by the user. Therefore, the water outlet can be rotated without touching the water faucet device or the operating part. This makes it difficult for the water faucet device and the operating part to become dirty, and more reliably prevents a decrease in appearance and the need for extra cleaning. It also more reliably prevents a decrease in hygiene due to the adhesion of dirt, bacteria, viruses, etc. to the water faucet device and the operating part.

Furthermore, according to the above-mentioned means 1 , the water discharge part and the water outlet can be rotated by rotating the faucet main body, which corresponds to the base side of the faucet device. Therefore, it is possible to prevent the structure related to the rotation of the water outlet from becoming complicated.

According to the above-mentioned means 1 , at least the electric current operating part of the rotating device is arranged in the rear space where it is difficult or impossible for the user to see. Therefore, a neat appearance is more reliably presented to the user, and the appearance quality can be improved. Furthermore, by arranging the electric current operating part in the rear space, it is possible to more reliably prevent the electric current operating part from being adversely affected by water.

In addition, according to the above-mentioned means 1 , since the driving force is transmitted to the part of the faucet body located in the front space through the longitudinal transmission part, it is not necessary to use a faucet body that penetrates the mounting target part. This allows the faucet body to be made smaller (lighter), and the faucet body and, in turn, the smoothness of the rotation of the spout can be improved. In addition, a larger installation space can be secured below the faucet body for the water supply pipe, hot water supply pipe, water conveyance pipe, etc. As a result, it becomes easier to naturally perform the desired functions of the faucet device, and the ease of installation of the device (system) can be improved.

Means 2. A faucet system including a faucet device that is attached to a predetermined attachment portion and has a water outlet that discharges water into a water storage portion in a tank body,
A rotating device having an energization operation part that can be operated by energization;
an operation unit for operating the energization operation unit, the operation unit being configured so as to be operable by a user without touching the operation unit with his/her hands;
The faucet device is configured to be rotatable such that the water outlet rotates left and right as seen by a user by operating the operating unit to operate the energizing operating unit,
the operation unit includes a non-contact sensor capable of detecting an approaching object without contact and outputting a predetermined detection signal when the object is detected;
The rotating device is configured to be able to control the operation of the energizing operation unit based on an output of the detection signal,
The water faucet device has a water discharge portion that extends from the attachment portion side toward the water storage portion side when viewed in a plan view and has the water discharge port at a tip end side,
As the non-contact type sensor, a first sensor and a second sensor are provided, which are arranged on both sides of the water discharger, on the left and right sides as seen from a user, and each of which is capable of outputting the detection signal,
The faucet system is characterized in that the rotation device is configured to control the operation of the energizing operating unit so that the water outlet rotates in a predetermined direction when the detection signal is output from the first sensor, and rotates in the direction opposite to the predetermined direction when the detection signal is output from the second sensor.

According to the above-mentioned method 2 , since a non-contact sensor is used, the water outlet can be rotated without touching the operation part. This makes it possible to more reliably prevent deterioration of the appearance and unnecessary cleaning work, and also to improve hygiene.

In addition, according to the above-mentioned means 2 , the first and second sensors are provided on both sides of the water discharge section, on the left and right sides as seen from the user, so that when one sensor is used to rotate the water discharge port, it is unlikely that the other sensor will mistakenly detect an object to be detected. Therefore, good operability can be obtained.

Furthermore, according to the above-mentioned means 2 , when the first sensor detects an object to be detected (e.g., the user's hand) and outputs a detection signal, the water outlet (water outlet section) rotates in a predetermined direction, and when the second sensor detects an object to be detected and outputs a detection signal, the water outlet can rotate in the opposite direction to the predetermined direction. For example, when the first sensor is provided on the right side and the second sensor is provided on the left side as viewed from the user, when the first sensor detects an object to be detected, the water outlet can rotate leftward as viewed from the user so as to move away from the object to be detected, and when the second sensor detects an object to be detected, the water outlet can rotate rightward as viewed from the user so as to move away from the object to be detected. Of course, it is also possible to configure the water outlet to rotate so as to move closer to the object to be detected when the sensor detects the object to be detected.

In this way, according to the above-mentioned means 2 , when one of the sensors arranged on the left and right sides as seen from the user detects an object, the water outlet can be rotated in a direction according to the position of the detected object. This makes it easier for the user to understand the method of operating the position of the water outlet, and allows the water outlet to be rotated more intuitively. This further increases convenience for the user.

Means 3. A faucet system including a faucet device that is attached to a predetermined attachment portion and has a water outlet that discharges water into a water storage portion in a tank body,
A rotating device having an energization operation part that can be operated by energization;
an operation unit for operating the energization operation unit, the operation unit being configured so as to be operable by a user without touching the operation unit with his/her hands;
The faucet device is configured to be rotatable such that the water outlet rotates left and right as seen by a user by operating the operating unit to operate the energizing operating unit,
the operation unit includes a non-contact sensor capable of detecting an approaching object without contact and outputting a predetermined detection signal when the object is detected;
The rotating device is configured to be able to control the operation of the energizing operation unit based on an output of the detection signal,
The water faucet device has a water discharge portion that extends from the attachment portion side toward the water storage portion side when viewed in a plan view and has the water discharge port at a tip end side,
As the non-contact type sensor, a first sensor and a second sensor are provided, which are arranged on both sides of the water discharge portion, on the left and right sides as seen from a user, and each of which is capable of outputting the detection signal,
The faucet system is characterized in that the rotation device is configured to control the operation of the energized operating unit so that when the detection signals are output from each of the first sensor and the second sensor, the water outlet rotates in a direction corresponding to the order in which the detection signals are output.

According to the above-mentioned means 3 , when a detection signal is output from each of the first and second sensors, the water outlet (water outlet section) can be rotated in a direction according to the output order of these detection signals. For example, if the first sensor is provided on the right side and the second sensor is provided on the left side as viewed from the user, when the detection signals are output from the first sensor and then the second sensor, that is, when the detected object is moving from right to left, the water outlet can be rotated to the left, and when the detection signals are output from the second sensor and then the first sensor, that is, when the detected object is moving from left to right, the water outlet can be rotated to the right.

Therefore, according to the above-mentioned means 3 , when the sensors arranged on the left and right sides as seen from the user detect a moving object (for example, the user's hand), the water outlet can be rotated in a direction corresponding to the direction of movement of the object. Therefore, the water outlet can be rotated with the same feeling of operation as when the user holds the water outlet part in his/her hand and rotates it. This further increases convenience for the user.

In addition, the water outlet can be prevented from rotating when only one sensor detects an object to be detected, or when both sensors detect an object simultaneously. This makes it less likely that the water outlet will rotate unintentionally, which also contributes to improving convenience for users.

The faucet system is characterized in that the rotation device is configured to control the operation of the energizing operating unit so as to continue rotating the water outlet while the object to be detected is detected by the first sensor and the second sensor, and to stop the rotation of the water outlet when the object to be detected is no longer detected.

According to the above-mentioned means 4, the detected object is moved in accordance with the rotation of the water outlet, and the detected object is kept close to the first sensor or the second sensor, so that the water outlet can be rotated as if being pulled or pushed by the detected object.

A rotating device having an energization operation part that can be operated by energization;
an operation unit for operating the energization operation unit, the operation unit being configured so as to be operable by a user without touching the operation unit with his/her hands;

The faucet system is characterized in that the rotation device is configured to control the operation of the energizing operating unit so that the water outlet rotates in a predetermined direction when the detection signal is output from the first sensor, and rotates in the direction opposite to the predetermined direction when the detection signal is output from the second sensor.

According to the above-mentioned means 5, the same effects as those of the above-mentioned means 2 are achieved.

Furthermore, according to the above-mentioned means 5 , since the first sensor and the second sensor are provided at the tip of the water discharger, the visibility of both sensors is improved, thereby improving convenience for the user.

Furthermore, when manually rotating the water outlet, the tip of the water outlet is usually the object of operation, but according to the above-mentioned means 5 , a non-contact sensor that is the object of operation is provided at the tip of the water outlet. Therefore, it is possible to intuitively rotate the water outlet by an operation similar to that in the case of manual operation, further improving convenience.

According to the seventh aspect, the same effects as those of the fourth aspect can be achieved.

Means 8. A water faucet system including a water faucet device that is attached to a predetermined attachment portion and has a water outlet that discharges water into a water storage portion in a tank body,
A rotating device having an energization operation part that can be operated by energization;
an operation unit for operating the energization operation unit, the operation unit being configured so as to be operable by a user without touching the operation unit with his/her hands;
The faucet device is configured to be rotatable such that the water outlet rotates left and right as seen by a user by operating the operating unit to operate the energizing operating unit,

A faucet system characterized in that the rotation device is configured to control the operation of the energizing operating unit so as to stop the rotation of the water outlet when the detection signal is output while the water outlet is rotating.

According to the above-mentioned means 8 , when an object to be detected is brought close to the non-contact sensor while the water outlet is rotating and a new detection signal is output, the rotation of the water outlet can be stopped. Therefore, the operation related to the rotation of the water outlet can be performed more easily.

Means 9 : The water faucet system according to any one of means 2 to 8, characterized in that the rotation device is configured to be in a state in which the operation of the energizing operation unit for rotating the water outlet can be controlled when the detection of the object by the non-contact sensor continues for a predetermined period of time or more .

According to the above-mentioned means 9 , when the non-contact sensor continues to detect the object for a predetermined time or more, for example, when the detection signal is continuously output for a predetermined time or more, the rotating device is in a state where the operation of the energizing operation unit for rotating the spout can be controlled. In other words, it is only when the non-contact sensor continues to detect the object for a predetermined time or more that the control for rotating the spout can be performed. Therefore, it is possible to further reduce the occurrence of unintended rotation of the spout, and to further improve convenience.

Means 10 : A solenoid valve capable of switching between water discharge and water stop at the water discharge port is provided,
the rotating device is configured to be able to control an operation of the energizing operation unit or the solenoid valve when the detection signal is output,
The faucet system described in any of means 2 to 9, characterized in that the rotation device has a switching means that can switch to a rotation control mode in which the operation of the energized operating unit can be controlled when the detection signal is output from the non-contact sensor, or a water discharge/stop control mode in which the operation of the solenoid valve can be controlled when the detection signal is output from the non -contact sensor.

According to the above-mentioned means 10 , the switching means can switch between a rotation control mode in which the operation of the energized operating unit can be controlled when a detection signal is output from the non-contact sensor, and a water discharge/stop control mode in which the operation of the solenoid valve can be controlled when a detection signal is output from the non-contact sensor. In other words, the object to be controlled in response to the output of the detection signal can be switched between the energized operating unit and the solenoid valve. Therefore, the operation related to the rotation of the spout and the operation related to the spout/stop at the spout can be performed using a common non-contact sensor. This makes it unnecessary to provide a sensor for spouting and stopping water separately from the non-contact sensor, and simplifies the faucet system. As a result, it is possible to reduce the costs associated with the manufacture and maintenance of the faucet system.

Means 11. The water faucet system according to any one of means 1 to 10, characterized in that the rotating device is configured to be able to control the operation of the energizing operation unit so that the spout is placed at a predetermined set position when the operation unit is operated in a predetermined manner.

The "preset position" may be, for example, the center position within the rotational range of the spout or a side position within the rotational range. Of course, these are just examples, and the "preset position" may be any fixed position within the rotational range of the spout, and may be set appropriately according to the conditions and environment of use.

According to the above-mentioned means 11 , when the detection of the object to be detected is performed in a predetermined manner, for example, when the non-contact sensor detects the object a certain number of times within a certain time period or when the object to be detected continues for a certain time period, the spout can be automatically rotated to a set position (returned). This allows the spout to be returned to the set position without touching the faucet device, further improving convenience.

In addition, there is no need to wait for time to pass until the water outlet is placed (returned) to the set position, and the user can place the water outlet in the set position at their convenience without touching the faucet device. Therefore, in this respect as well, convenience for the user can be improved.

Hereinafter, an embodiment will be described with reference to the drawings.
First Embodiment
1 to 4, the faucet system 1 is attached to a kitchen sink 100 (hereinafter simply referred to as "sink 100"). First, prior to describing the faucet system 1, the sink 100 will be described.

The sink 100 comprises a sink 101, a base 102 to which the sink 101 is fixed at the top and which has a space inside, and two doors 103 for opening and closing the front opening of the base 102. The sink 101 comprises a water storage section 101a capable of storing water, and a flat top plate section 101b which protrudes outward from the top of the water storage section 101a. In this embodiment, the sink 101 corresponds to the "tank body" and the top plate section 101b corresponds to the "attachment target section."

The sink 101 is divided into a front space 104 that is visible to the user, and a back space 105 that is not or is difficult to see by the user. In this embodiment, the back space 105 refers to the space inside the base 102. In addition, a mounting hole 101c (see FIG. 3, etc.) that penetrates in the vertical direction is formed in a portion of the top plate portion 101b that is located behind the water storage portion 101a as seen from the user.

Next, the faucet system 1 will be described. The faucet system 1 is primarily used to switch on and off the supply of water to the sink 101 (particularly the water storage section 101a). The faucet system 1 includes a holding tube section 2, an outer component section 3, an inner component section 4, a water discharge/stop sensor 5, an electromagnetic valve 6, a rotating device 7, and an operating section 8.

The retaining tube 2 is a part that functions as a mounting base for the outer component 3 and the like. The retaining tube 2 is cylindrical overall, and as shown in FIG. 5, has a flange 21 formed on the upper outer periphery and a male thread 22 formed on the outer periphery below the flange 21. The retaining tube 2 is attached to the top plate 101b in a non-rotatable state by inserting it through the mounting hole 101c and screwing the male thread 22 into a specified nut member 11a, so that the top plate 101b is sandwiched between the flange 21 and the nut member 11a.

Returning to FIG. 3, the outer component 3 covers and protects the inner component 4, forms a space for arranging cables (lead wires) for transmitting and receiving signals between the inner component 4, and is also used to obtain a good appearance quality in the faucet system 1. The outer component 3 has a cylindrical shape with a middle part curved at a substantially right angle, and includes an outer first tubular part 31 extending vertically, an outer second tubular part 32 extending horizontally, and an outer curved tubular part 33 of a curved shape that connects both tubular parts 31, 32.

The first outer tube portion 31 is inserted into the inner circumference of the retaining tube portion 2 with a step portion 31a (see FIG. 5) formed on the outer circumference placed on the upper end surface of the retaining tube portion 2. This allows the first outer tube portion 31, and thus the outer component portion 3, to rotate on a rotation axis Ar (see FIG. 5) that passes through the center of the mounting hole 101c and extends vertically. The second outer tube portion 32 also has an opening 32a that penetrates in the vertical direction at a position vertically above the water storage portion 101a at the lower end of the tip side of the second outer tube portion 32.

The inner component 4 functions as a flow path for water to be supplied to the sink 101 (water storage section 101a). The inner component 4 is cylindrical with a middle section curved at a substantially right angle, and includes an inner first tubular section 41 extending vertically, an inner second tubular section 42 extending horizontally overall, and an inner curved tubular section 43 that is curved and connects both tubular sections 41, 42.

The tip of the second inner tubular portion 42 is provided with a water outlet 10a that opens vertically downward. The tip of the second inner tubular portion 42 passes through the opening 32a and is positioned outside the outer component 3, so that the water outlet 10a is positioned vertically above the water storage portion 101a of the sink 101.

Furthermore, the inner component 4 is held by the outer component 3. This allows the inner component 4 to rotate together with the outer component 3 when the outer component 3 rotates.

In this embodiment, the faucet main body 9 that protrudes upward from the sink 101 (top plate 101b) is formed by the outer first tubular portion 31 and the inner first tubular portion 41. The faucet main body 9 in this embodiment is attached to the sink 101 (top plate 101b) by passing through the mounting hole 101c.

In addition, in this embodiment, the outer second tubular portion 32, the outer curved tubular portion 33, the inner second tubular portion 42, and the inner curved tubular portion 43 form a water discharge portion 10 that extends from a portion of the faucet main body 9 located in the front space 104 toward an upper position of the water storage portion 101a in the sink 101, that is, extends from the top plate portion 101b toward the water storage portion 101a when viewed in a plan view, and has a water discharge port 10a at its tip. In this embodiment, the faucet main body 9 and the water discharge portion 10 form a water faucet device 14 attached to the top plate portion 101b.

The water discharge/stop sensor 5 is an object to be operated when switching water discharge or water stop at the water outlet 10a, and in this embodiment, it is provided on the front surface of the water faucet main body 9 (first outer tube portion 31). The water discharge/stop sensor 5 is composed of, for example, an infrared sensor, and includes an irradiating portion that irradiates light of a predetermined wavelength to a predetermined range in front of the water faucet main body 9 (first outer tube portion 31), a light receiving portion (light receiving element) for detecting the light reflected by a detected object (e.g., a hand or an object), and a signal output portion that outputs a predetermined water discharge/stop signal when the light receiving portion detects the light (not shown). When the light receiving portion detects the light, the signal output portion outputs a water discharge/stop signal to the solenoid valve control device 12 described later via a predetermined cable (not shown). The position of the water discharge/stop sensor 5 may be changed as appropriate.

The solenoid valve 6 is a device for switching between discharging and stopping water at the water outlet 10a. The solenoid valve 6 is interposed between the inner component 4 and a specified water supply means (not shown). The solenoid valve 6 switches between discharging and stopping water at the water outlet 10a by switching between supplying and stopping water supply from the water supply means to the inner component 4. In this embodiment, the solenoid valve 6 is rotatable relative to the inner component 4, and is configured not to rotate in accordance with the rotation of the faucet main body 9 (the outer component 3 or the inner component 4).

The operation of the solenoid valve 6 is controlled by a solenoid valve control device 12 (see FIG. 9). In this embodiment, the solenoid valve control device 12 controls the operation of the solenoid valve 6 so that the water discharge or stop at the water outlet 10a is alternately switched between discharge and stop each time a water discharge/stop signal is output from the water discharge/stop sensor 5. Therefore, in this embodiment, the water discharge or stop at the water outlet 10a is alternately switched between discharge and stop each time an object is detected by the water discharge/stop sensor 5. The solenoid valve control device 12 can be configured, for example, integrally with the water discharge/stop sensor 5 or the solenoid valve 6.

The rotating device 7 is a device for rotating the faucet device 14 and therefore the water outlet 10a by rotating the faucet main body 9. The rotating device 7 has at least the motor 72 arranged in the rear space 105, and in particular, in this embodiment, all of the components of the rotating device 7 (the case 71, motor 72, transmission part 73, pressing part 74, clutch operation detection switch 75, and control device 76, which are described below) are arranged in the rear space 105. This makes the rotating device 7 invisible or difficult to see from the outside (user).

As shown in Figures 5 to 9, the rotation device 7 includes a case 71, a motor 72, a transmission unit 73, a pressing part 74, a clutch operation detection switch 75, and a control device 76. In this embodiment, the motor 72 constitutes the "energization operation unit," and the clutch operation detection switch 75 constitutes the "clutch operation detection means." For ease of explanation, the configuration of the control device 76 will be explained after the explanation of the operation unit 8.

The case 71 accommodates the motor 72, transmission unit 73, etc. inside, and functions as an attachment unit for the rotating device 7 relative to the holding tube portion 2. In this embodiment, the case 71 includes a first case component 711, a second case component 712, and a third case component 713, and is configured by assembling these case components 711 to 713 using snap-fit engagement or the like. In this embodiment, multiple seal members 77 are provided to prevent water from entering at least the space in the case 71 that accommodates the motor 72.

The first case component 711 is for mounting the rotating device 7 to the holding tube 2 while closing one end opening (upper opening) of the second case component 712. The first case component 711 has a shape including a semicircular portion and a semi-elliptical portion protruding from the center of the arc of the semicircular portion in a plan view. The semi-elliptical portion of the first case component 711 has a screw hole portion 711a (see FIG. 5) having a female thread, and the male thread portion 22 of the holding tube 2 is screwed into the screw hole portion 711a, thereby mounting the case 71 and the rotating device 7 to the holding tube 2. As a result, the rotating device 7 is installed in a state where it cannot rotate with respect to the top plate portion 101b. The mounting target of the rotating device 7 is not necessarily limited to the holding tube 2, and may be, for example, the base 102.

In addition, in this embodiment, the end face of the nut member 11b, which is screwed into the male threaded portion 22 below the nut member 11a, is in surface contact with the first case component 711. After adjusting the orientation of the rotating device 7 to a desired angle, the end face of the nut member 11b is in surface contact with the first case component 711 while applying a tightening torque to the nut member 11b, thereby more reliably maintaining the orientation of the rotating device 7 in a constant state.

The second case component 712 supports the transmission unit 73 and the like, and functions as the main housing for the motor 72, the transmission unit 73, etc.

The third case component 713 is used to support the transmission part 73 etc. while blocking the other end opening (lower opening) of the second case component 712.

The motor 72 is a power source for rotating the faucet main body 9 and the water discharge portion 10 (i.e., the faucet device 14). The motor 72 is housed in the case 71, although not shown, and has a motor shaft (not shown) that can rotate in both directions when electricity is applied. When electricity is applied to the motor 72, the driving force generated by the rotation of the motor shaft is transmitted to the transmission portion 73.

The transmission unit 73 constitutes a transmission path of the driving force from the motor 72 to the faucet main body 9 (in this embodiment, the outer component 3). The transmission unit 73 includes a motor-side transmission unit 731, a first intermediate transmission unit 732, a second intermediate transmission unit 733, and a spout-side transmission unit 734, and the driving force for rotating the faucet device 14 is transmitted from the motor 72 to the faucet main body 9 in this order.

The motor-side transmission unit 731 is a part to which the driving force from the motor 72 is directly transmitted, and is configured by connecting rotatable reduction gears, shaft parts, etc. in an interlocking manner. The motor-side transmission unit 731 receives the driving force transmitted from the motor 72, and transmits the driving force to the first intermediate transmission unit 732.

The first intermediate transmission part 732 is a disk-shaped part that rotates on a rotation axis parallel to the rotation axis Ar by the driving force transmitted from the motor side transmission part 731. A first clutch gear 732a having a plurality of teeth arranged in a circular shape is formed on an end face of the first intermediate transmission part 732 (see FIG. 8, etc.). The first clutch gear 732a is located on the motor 72 side (relative to the second clutch gear 733a described later) in the transmission path of the driving force from the motor 72, and rotates together with the first intermediate transmission part 732.

The second intermediate transmission part 733 is a part that rotates on the same rotation axis as the rotation axis of the first intermediate transmission part 732 by the driving force transmitted from the first intermediate transmission part 732, and has a shape that combines a circular part and a sector-shaped part protruding from the circular part in a plan view. The second clutch gear 733a, which has multiple teeth arranged in a circular shape, is formed in the circular part of the second intermediate transmission part 733 at a position facing the first clutch gear 732a (see FIG. 7). The second clutch gear 733a is located closer to the faucet main body 9 than the first clutch gear 732a in the driving force transmission path, and is usually engaged with the first clutch gear 732a and rotates when the driving force is transmitted from the first clutch gear 732a.

A driving gear 733b having multiple teeth arranged in an arc is formed on the outer periphery of the sector-shaped portion of the second intermediate transmission part 733 (see FIG. 7). When the second intermediate transmission part 733 rotates in response to the operation of the motor 72, the driving gear 733b rotates on a rotation axis parallel to the rotation axis Ar.

As described above, the second clutch gear 733a and the drive gear 733b are provided in the second intermediate transmission part 733. In other words, in this embodiment, the second clutch gear 733a and the drive gear 733b are configured from a single part (the second intermediate transmission part 733).

Furthermore, the second intermediate transmission part 733 is disposed between the first case component 711 and the second case component 712, but is normally positioned on the second case component 712 (first intermediate transmission part 732) side due to the pressing force applied by the pressing part 74, and is disposed with a predetermined gap from the first case component 711. The second intermediate transmission part 733 is movable toward this gap, and when the second intermediate transmission part 733 moves toward the gap, the meshing of both clutch gears 732a, 733a is released.

The outlet side transmission part 734 is a part that rotates on the same rotation axis as the rotation axis Ar by the driving force transmitted from the second intermediate transmission part 733. The outlet side transmission part 734 is fixed to the outer periphery of the outer component part 3 (faucet main body part 9), and the outer component part 3 (faucet main body part 9) rotates in conjunction with the rotation of the outlet side transmission part 734.

In addition, a driven gear 734a with multiple teeth arranged in the circumferential direction is formed in a predetermined range on the outer periphery of the outlet side transmission part 734, and the driven gear 734a is meshed with the drive gear 733b. As a result, when the motor 72 is operated to rotate the drive gear 733b, the driven gear 734a rotates in conjunction with the rotation of the drive gear 733b. As a result, the driving force by the operation of the motor 72 is transmitted to the part of the faucet main body 9 located in the back space 105, causing the faucet device 14 and therefore the outlet 10a to rotate.

In this embodiment, when the water faucet device 14 becomes unable or difficult to rotate due to contact of the water discharge part 10 with some obstacle such as a hand or an object, the second intermediate transmission part 733 (second clutch gear 733a) is configured to become unable or difficult to rotate. The second intermediate transmission part 733 (second clutch gear 733a) also becomes unable to rotate when it reaches the limit of its rotatable range and comes into contact with the case 71. Here, when the second intermediate transmission part 733 reaches the limit of its rotatable range, the water faucet device 14 also reaches the limit of its rotatable range. In this embodiment, the rotatable range of the water faucet device 14 (water discharge part 10) is set to a predetermined angle (e.g., 120°) less than 180°, and in this embodiment, the water faucet device 14 (water discharge part 10) can be rotated by a predetermined angle (e.g., 60°) to the left and right as seen by the user. However, the range in which the faucet device 14 (water discharge unit 10) can rotate is not limited to the above and may be changed as appropriate.

The pressing part 74 is a part for pressing the second intermediate transmission part 733 against the first intermediate transmission part 732. In this embodiment, the pressing part 74 is configured by a predetermined coil spring, and is provided in a compressed state between the first case component 711 and the second intermediate transmission part 733. As a result, the second intermediate transmission part 733 is normally pressed against the first intermediate transmission part 732 without moving toward the gap on the first case component 711 side described above, and the second clutch gear 733a is maintained in a state of meshing with the first clutch gear 732a.

By providing the transmission part 73 and the pressing part 74 configured as described above, when the water faucet device 14 becomes unable or difficult to rotate during operation of the motor 72, and the second clutch gear 733a becomes unable or difficult to rotate, the driving force from the motor 72 acts to move the second intermediate transmission part 733 (second clutch gear 733a) toward the gap. That is, the second intermediate transmission part 733 (second clutch gear 733a) moves in a direction to release the meshing of both clutch gears 732a, 733a. As a result, the transmission of the driving force from the first clutch gear 732a to the second clutch gear 733a is cut off, and the transmission of the driving force from the motor 72 to the water faucet main body 9 is cut off. Therefore, when the water faucet device 14 becomes unable or difficult to rotate, further rotation of the water faucet device 14 is stopped. In this embodiment, the first clutch gear 732a, the second clutch gear 733a, and the pressing part 74 constitute a clutch part 78 that can cut off the transmission of driving force when the water discharge part 10 becomes unable or difficult to rotate while the motor 72 is operating (see FIG. 5).

In addition, in this embodiment, the clutch unit 78 is provided, so that even when the water faucet device 14 reaches the limit of its rotational range due to the operation of the motor 72, the clutch unit 78 is activated and the rotation of the water discharge unit 10 is stopped.

Furthermore, by providing the clutch unit 78, it is possible to rotate the water faucet device 14 (water discharge unit 10) by applying an external force (e.g., the user pushing or pulling the water discharge unit 10) without operating the motor 72, for example during a power outage.

The clutch operation detection switch 75 is used to detect that the second intermediate transmission part 733 (second clutch gear 733a) has moved toward the gap, i.e., in the direction that disengages the two clutch gears 732a, 733a.

The clutch operation detection switch 75 has a protrusion that can protrude into and retract from the housing space of the second intermediate transmission part 733 in the case 71 (see FIG. 8; not shown in FIG. 5). When the protrusion protrudes into the housing space (more specifically, when the protrusion changes from a recessed state to a protruding state), the clutch operation detection switch 75 outputs a predetermined forced stop signal to the control device 76. That is, when the second intermediate transmission part 733 (second clutch gear 733a) moves toward the gap against the pressing force applied by the pressing part 74, a forced stop signal is output from the clutch operation detection switch 75 to the control device 76.

Next, the operation unit 8 will be described. The operation unit 8 is used when the user operates the motor 72 to rotate the faucet device 14 without touching it with his or her hands. The operation unit 8 is equipped with a non-contact sensor such as an infrared sensor, and a first sensor 81 and a second sensor 82 are provided as non-contact sensors.

As shown in Figures 1 and 2, the first sensor 81 is located on one of the two sides of the water discharger 10, on the right side as seen by the user. In contrast, the second sensor 82 is located on the other of the two sides of the water discharger 10, on the left side as seen by the user.

The first sensor 81 and the second sensor 82 each include an irradiation unit that irradiates a predetermined range on the side of the water discharge unit 10 with light of a predetermined wavelength at fixed short intervals, a light receiving unit (light receiving element) for detecting the light reflected by a detected object (e.g., a hand), and a signal output unit that outputs a predetermined detection signal when the light is detected by the light receiving unit (not shown). Both sensors 81 and 82 can detect an approaching detected object by the reflected light being incident on the light receiving unit, and when the detected object is detected, the signal output unit outputs a detection signal. The output detection signal is input to the control device 76 via a predetermined signal line (not shown). In this embodiment, when the first sensor 81 detects a detected object, that is, when the reflected light is input to the light receiving unit, it outputs a first detection signal as a detection signal. On the other hand, when the second sensor 82 detects a detected object, it outputs a second detection signal as a detection signal.

Next, the control device 76 will be described. The control device 76 is configured, for example, by a microcomputer equipped with a CPU, RAM, input/output terminals, etc., and includes a processing unit 761 and a motor control unit 762.

The processing unit 761 performs calculations based on the input signals and generates commands according to the calculation results. In more detail, when the first detection signal is output from the first sensor 81 while the motor 72 is not operating (i.e., when the first detection signal is input to the control device 76), the processing unit 761 generates a first rotation command as a command to rotate the water faucet device 14 and the water outlet 10a in a predetermined direction (in this embodiment, a direction from right to left as seen by the user). On the other hand, when the second detection signal is output from the second sensor 82 while the motor 72 is not operating (i.e., when the second detection signal is input to the control device 76), the processing unit 761 generates a second rotation command as a command to rotate the water faucet device 14 and the water outlet 10a in the opposite direction to the predetermined direction (in this embodiment, a direction from left to right as seen by the user). The processing unit 761 is capable of grasping whether the motor 72 is operating via the motor control unit 762.

In addition, when the first or second detection signal is output from the sensors 81 and 82 while the motor 72 is operating, the processing unit 761 generates a rotation stop command as a command to stop the operation of the motor 72 and, in turn, the rotation of the faucet device 14.

Furthermore, when a forced stop signal is input from the clutch operation detection switch 75, the processing unit 761 generates a forced stop command as a command to forcibly stop the motor 72.

The motor control unit 762 controls the operation of the motor 72 based on the command generated by the processing unit 761. More specifically, when a first rotation command is generated, the motor control unit 762 controls the supply of electricity to the motor 72 so that the motor shaft rotates in a specific direction. As a result, the water faucet device 14 (the water discharge unit 10 and the water outlet 10a) rotates in a specific direction (in this embodiment, a direction from right to left as seen by the user) unless it is impossible or difficult to rotate. On the other hand, when a second rotation command is generated, the motor control unit 762 controls the supply of electricity to the motor 72 so that the motor shaft rotates in the opposite direction to the specific direction. As a result, the water faucet device 14 rotates in the opposite direction to the specific direction (in this embodiment, a direction from left to right as seen by the user) unless it is impossible or difficult to rotate.

When a rotation stop command or a forced stop command is generated, the motor control unit 762 cuts off the current to stop the operation of the motor 72. This stops the rotation of the faucet device 14.

The motor control unit 762 may control the operation of the motor 72 so that when a forced stop command is generated, the water faucet device 14 is rotated slightly in the opposite direction to the previous rotation direction and then stopped. In this case, the water discharge unit 10 and other parts are stopped in a state away from obstacles, etc., so that the load on the obstacles, water discharge unit 10, transmission unit 73, etc. can be reduced. In addition, both clutch gears 732a, 733a can be more reliably returned to the meshed state, ensuring smoother rotation of the water faucet device 14 the next time it is rotated.

Next, the normal operation of the processing unit 761 related to the rotation of the water faucet device 14 (water outlet 10a) in this embodiment will be described with reference to the flowchart in FIG. 10. Note that the normal operation of the processing unit 761 is repeated at regular short intervals.

First, in step S11, it is confirmed whether the motor 72 is operating. If the motor 72 is operating (i.e., the water faucet device 14 is rotating) (step S11: Yes), the process proceeds to step S12. On the other hand, if the motor 72 is not operating (i.e., the water faucet device 14 is stopped) (step S11: No), the process proceeds to step S14.

In step S12, it is confirmed whether the first or second detection signal has been output from the sensors 81, 82 (i.e., whether the first or second detection signal has been input to the control device 76). If the first or second detection signal has been output (step S12: Yes), a rotation stop command is generated in step S13, and the process returns to step S11. Upon generating the rotation stop command, the motor control unit 762 cuts off the power to the motor 72, and the operation of the motor 72 is stopped. As a result, the rotation of the water faucet device 14 (the water outlet 10a) is stopped. On the other hand, if neither the first nor second detection signal has been output while the motor 72 is operating (step S12: No), step S13 is skipped and the process returns to step S11.

In step S14, it is confirmed whether a first detection signal has been output from the first sensor 81 (i.e., whether a first detection signal has been input to the control device 76). If a first detection signal has been output (step S14: Yes), a first rotation command is generated in step S15, and the process returns to step S11. With the generation of the first rotation command, the water faucet device 14 (water outlet 10a) rotates in a predetermined direction. On the other hand, if a first detection signal has not been output (step S14: No), the process proceeds to step S16.

In step S16, it is confirmed whether a second detection signal has been output from the second sensor 82 (i.e., whether a second detection signal has been input to the control device 76). If a second detection signal has been output (step S16: Yes), a second rotation command is generated in step S17, and the process returns to step S11. By generating the second rotation command, the water faucet device 14 (water outlet 10a) rotates in the direction opposite to the specified direction. On the other hand, if a second detection signal has not been output (step S16: No), no command is generated and the process returns to step S11.

When a forced stop signal is output from the clutch operation detection switch 75 (i.e., when a forced stop signal is input to the control device 76), the processing unit 761 interrupts the normal operation described above and generates an emergency stop command. As a result, if current is flowing to the motor 72, current to the motor 72 is cut off, and the operation of the motor 72 and therefore the rotation of the faucet device 14 are forcibly stopped.

The faucet system 1 according to this embodiment, configured as described above, operates as follows when operated by the user. That is, as shown in FIG. 11, when the faucet device 14 is stopped and the user brings a detected object Do, such as a hand, close to the first sensor 81, the faucet device 14 and therefore the water outlet 10a rotate in a predetermined direction (in this embodiment, a direction from right to left as seen by the user, away from the detected object Do).

On the other hand, as shown in FIG. 12, when the user brings the detected object Do close to the second sensor 82 while the water faucet device 14 is stopped, the water faucet device 14 and therefore the water outlet 10a rotate in the direction opposite to the specified direction (in this embodiment, from left to right as seen by the user, away from the detected object Do).

As shown in FIG. 13, if the object to be detected Do is brought close to the first sensor 81 or the second sensor 82 again while the water faucet device 14 is rotating, the rotation of the water faucet device 14 and therefore the water outlet 10a is stopped. At this time, the rotation of the water faucet device 14 can be stopped by placing the object to be detected Do, such as a hand, forward in the rotation direction of the water outlet 10. In other words, it is possible to stop the rotation of the water faucet device 14 by a natural action that is thought to be likely to be performed when stopping the rotation of the water faucet device 14.

Furthermore, as shown in FIG. 14, when the water faucet device 14 reaches the limit of its rotational range, the clutch operation detection switch 75 operates and the rotation of the water faucet device 14 is stopped. In addition, if the water discharge part 10 or the like comes into contact with an obstacle or the like and is unable or difficult to rotate, the clutch operation detection switch 75 also operates and the rotation of the water faucet device 14 is stopped.

As described above in detail, according to this embodiment, the water outlet 10a can be rotated without touching the water faucet device 14 or the operating unit 8 (sensors 81, 82). This makes it possible to make the water faucet device 14 and the operating unit 8 less susceptible to dirt, and more reliably prevents a decrease in appearance and the need for extra cleaning. It also more reliably prevents a decrease in hygiene due to the adhesion of dirt, bacteria, viruses, etc. to the water faucet device 14 and the operating unit 8.

The entire rotating device 7 is placed in the rear space 105, which is invisible or difficult for the user to see. This presents a neat appearance to the user, improving the appearance quality.

Furthermore, since the operating unit 8 is made up of non-contact sensors (first sensor 81 and second sensor 82), the water outlet 10a can be rotated without touching the operating unit 8. This makes it possible to more reliably prevent poor appearance and unnecessary cleaning work from occurring, and also improves hygiene.

In addition, the portion of the faucet main body 9 to which the power generated by the operation of the motor 72 is transmitted is located in the rear space 105. Therefore, the structure of the portion of the faucet system 1 located in the front space 104 can be further simplified. As a result, the appearance quality can be further improved.

In addition, the first sensor 81 and the second sensor 82 are provided on both sides of the water discharge unit 10, on the left and right sides as seen by the user, so that when one of the sensors 81 (82) is used to rotate the water discharge port 10a, it is unlikely that the object to be detected Do will be mistakenly detected by the other sensor 82 (81). This provides good operability.

In addition, when one of the sensors 81, 82 arranged on the left and right sides as seen from the user detects the object to be detected Do, the water outlet 10a can be rotated in a direction according to the position of the object to be detected Do. This makes it easier for the user to understand how to operate the position of the water outlet 10a, and allows the water outlet 10a to be rotated more intuitively. This further increases convenience for the user.

In addition, when the object to be detected Do is brought close to the non-contact sensor (sensors 81, 82) while the water outlet 10a is rotating and a new first or second detection signal is output, the rotation of the water outlet 10a can be stopped. This makes it easier to perform operations related to the rotation of the water outlet 10a.

Furthermore, when the motor 72 is operating, if the water outlet 10 comes into contact with an obstacle such as a nearby person or object, making it impossible or difficult to rotate the water faucet device 14 (water outlet 10a), the clutch unit 78 can cut off the transmission of driving force from the motor 72 to the water faucet main body 9. This makes it possible to more reliably prevent situations in which the driving force from the motor 72 continues to be transmitted to the water faucet device 14 even when the water faucet device 14 is impossible or difficult to rotate. As a result, various benefits can be obtained, such as improved safety for users, protection of objects around the water faucet device 14, and prevention of breakdowns and damage to the water faucet system 1.

In addition, by providing the clutch portion 78, the faucet device 14 and thus the water outlet 10a can be rotated by applying an external force while preventing damage to parts, etc. This makes it more convenient for the user.

In addition, the clutch unit 78 of this embodiment is configured so that when the second clutch gear 733a is unable or difficult to rotate, the driving force transmitted from the motor 72 acts to move the second clutch gear 733a in a direction that disengages the two clutch gears 732a, 733a, and as a result, the transmission of the driving force is cut off. Therefore, the clutch unit 78 can be configured with a relatively simple structure using the two clutch gears 732a, 733a. This makes it possible to effectively reduce costs associated with the manufacture and maintenance of the faucet system 1.

In addition, the clutch operation detection switch 75 can detect that the second clutch gear 733a has moved in a direction that disengages the clutch gears 732a, 733a, i.e., that the clutch unit 78 has functioned, and the rotation device 7 can control the operation of the motor 72 to stop the rotation of the faucet device 14 based on the detection by the clutch operation detection switch 75. Therefore, when the clutch unit 78 has functioned, further rotation of the faucet device 14 can be stopped, improving safety for the user and more effectively protecting objects around the faucet device 14.

Furthermore, by providing a clutch operation detection switch 75, the operation of the motor 72 can be stopped when the faucet device 14 reaches the limit of its rotational range and the second clutch gear 733a becomes unable or difficult to rotate. Therefore, there is no need to provide a special mechanism for stopping the operation of the motor 72 when the faucet device 14 reaches the limit of its rotational range. This makes it possible to more effectively reduce costs associated with the manufacture of the faucet system 1.

In addition, the second intermediate transmission part 733 includes a second clutch gear 733a and a drive gear 733b, and the second clutch gear 733a and the drive gear 733b are configured as one part (the second intermediate transmission part 733). Therefore, the water faucet system 1 can be simplified, and costs related to manufacturing, etc. can be further reduced.
Second Embodiment
Next, the second embodiment will be described, focusing on the differences from the first embodiment. In the first embodiment, the first sensor 81 and the second sensor 82 are provided on both sides of the water discharger 10 (the outer second tubular portion 32). In contrast, in the second embodiment, as shown in Fig. 15, the first sensor 81 and the second sensor 82 are provided on the tip surface of the water discharger 10 (the outer second tubular portion 32) on the left and right sides as seen from the user. In the second embodiment, the first sensor 81 is located on the right side as seen from the user, and the second sensor 82 is located on the left side as seen from the user.

The first sensor 81 and the second sensor 82 are each equipped with an irradiation unit (not shown) that irradiates light of a predetermined wavelength, similar to the first embodiment described above. However, the light irradiation ranges of the two sensors 81, 82, i.e., the detection ranges of the object to be detected, do not overlap, and are set at positions separated to the left and right as viewed from the user. Similarly to the first embodiment described above, when an object to be detected is detected, the first sensor 81 outputs a first detection signal, and the second sensor 82 outputs a second detection signal.

Furthermore, in the first embodiment described above, the processing unit 761 controls the motor control unit 762 so that when the motor 72 is not operating, the processing unit 761 rotates the water faucet device 14 and the water outlet 10a in a predetermined direction when a first detection signal is output from the first sensor 81, and rotates the water faucet device 14 and the water outlet 10a in the opposite direction to the predetermined direction when a second detection signal is output from the second sensor 82. In other words, when the motor 72 is not operating, if a detection signal is output from one of the two sensors 81, 82, the water faucet device 14 is rotated unless the water faucet device 14 is unable or difficult to rotate.

In contrast, in the second embodiment, the processing unit 761 controls the operation of the motor 72 when the motor 72 is not operating, so that when a detection signal is output from each of the first sensor 81 and the second sensor 82, the water faucet device 14 and therefore the water outlet 10a rotate in a direction corresponding to the order in which these detection signals are output. In other words, in the second embodiment, the water faucet device 14 does not rotate when a detection signal is output from only one of the two sensors 81, 82.

Here, the operation of the processor 761 in the second embodiment will be described in more detail. When the motor 72 is not operating, the processor 761 generates a first rotation command as a command to rotate the water faucet device 14 in a predetermined direction (in this embodiment, a direction from right to left as seen by the user) when the first sensor 81 first outputs a first detection signal and the second sensor 82 outputs a second detection signal within a preset period of time (e.g., 0.5 seconds) from the first detection signal output. When the first rotation command is generated, the motor controller 762 controls the supply of electricity to the motor 72 so that the motor shaft rotates in a specific direction. As a result, the water faucet device 14 rotates in the predetermined direction unless it is impossible or difficult to rotate.

Furthermore, when the second sensor 82 first outputs a second detection signal while the motor 72 is not operating, and the first sensor 81 outputs a first detection signal within a preset period of time after the second detection signal is output, the processing unit 761 generates a second rotation command as a command to rotate the water faucet device 14 in the opposite direction to the specified direction (in this embodiment, the direction from left to right as seen by the user). When the second rotation command is generated, the motor control unit 762 controls the supply of electricity to the motor 72 so that the motor shaft rotates in the opposite direction to the specific direction. As a result, the water faucet device 14 rotates in the opposite direction to the specified direction unless it is impossible or difficult to rotate.

On the other hand, similar to the first embodiment described above, when the first detection signal or the second detection signal is output from the sensors 81, 82 during operation of the motor 72, the processing unit 761 generates a rotation stop command as a command to stop the rotation of the faucet device 14. In addition, when a forced stop signal is input from the clutch operation detection switch 75, the processing unit 761 generates a forced stop command as a command to forcibly stop the motor 72.

Next, the normal operation of the processing unit 761 related to the rotation of the water faucet device 14 (water outlet 10a) in this second embodiment will be explained with reference to the flowchart in Figure 16.

First, in step S21, it is confirmed whether the motor 72 is operating. If the motor 72 is operating (step S21: Yes), the process proceeds to step S22. If the motor 72 is not operating (step S21: No), the process proceeds to step S24. Note that the processing of steps S22 and S23 is almost the same as the processing of steps S12 and S13 in the first embodiment, and therefore a description of these will be omitted.

In step S24, it is confirmed whether or not a first detection signal has been output from the first sensor 81. If a first detection signal has been output (step S24: Yes), the process proceeds to step S25. On the other hand, if a first detection signal has not been output (step S24: No), the process proceeds to step S28.

In step S25, it is confirmed whether or not a second detection signal has been output from the second sensor 82. If a second detection signal has been output (step S25: Yes), the process proceeds to step S27. In step S27, a first rotation command is generated, and the process returns to step S21. By generating the first rotation command, the water faucet device 14 (the water outlet 10a) rotates in the specified direction.

On the other hand, if the second detection signal has not been output (step S25: No), in step S26, it is confirmed whether a certain time has passed since the output of the first detection signal. Whether the certain time has passed can be confirmed using a specified timer. If the certain time has not passed (step S26: No), the process returns to step S25. As a result, confirmation of whether the second detection signal has been output within the certain time after the output of the first detection signal (i.e., the process of step S25) is repeatedly performed. On the other hand, if the certain time has passed (step S26: Yes), that is, if the second detection signal has not been output within the certain time after the output of the first detection signal, the process returns to step S21.

If the determination in step S24 is negative, that is, if the first detection signal is not output when the motor 72 is not operating, in step S28, it is confirmed whether or not the second detection signal is output from the second sensor 82. If the second detection signal is output (step S28: Yes), the process proceeds to step S29. On the other hand, if the second detection signal is not output (step S28: No), the process returns to step S21.

In step S29, it is confirmed whether or not a first detection signal has been output from the first sensor 81. If a first detection signal has been output (step S29: Yes), the process proceeds to step S31. In step S31, a second rotation command is generated, and the process returns to step S21. By generating the second rotation command, the water faucet device 14 (the water outlet 10a) rotates in the direction opposite to the predetermined direction.

On the other hand, if the first detection signal has not been output (step S29: No), in step S30, it is checked whether a certain time has passed since the output of the second detection signal. If the certain time has not passed (step S30: No), the process returns to step S29. As a result, the process repeatedly checks whether the first detection signal has been output within the certain time after the second detection signal has been output. On the other hand, if the certain time has passed (step S30: Yes), that is, if the first detection signal has not been output within the certain time after the output of the second detection signal, the process returns to step S21.

As in the first embodiment, when a forced stop signal is output from the clutch operation detection switch 75, the processing unit 761 interrupts the normal operation and generates an emergency stop command. As a result, if current is flowing to the motor 72, current to the motor 72 is cut off, and the operation of the motor 72 is forcibly stopped.

The faucet system 1 according to the second embodiment configured as described above operates as follows when operated by the user. That is, as shown in FIG. 17, when the faucet device 14 is stopped, the user moves the object Do, such as a hand, from right to left, and brings the object Do close to the first sensor 81 and the second sensor 82 in that order, and the faucet device 14 and the water outlet 10a rotate in a predetermined direction (in the second embodiment, from right to left as seen by the user). On the other hand, as shown in FIG. 18, when the faucet device 14 is stopped, the user moves the object Do from left to right, and brings the object Do close to the second sensor 82 and the first sensor 81 in that order, and the faucet device 14 and the water outlet 10a rotate in the opposite direction to the predetermined direction (in the second embodiment, from left to right as seen by the user). That is, in the second embodiment, the faucet device 14 (water outlet 10a) rotates in the same direction as the movement of the object Do.

As in the first embodiment, if the object to be detected Do is brought close to the first sensor 81 or the second sensor 82 again while the water faucet device 14 is rotating, the rotation of the water faucet device 14 (water outlet 10a) is stopped. Also, when the water faucet device 14 reaches the limit of its rotational range, the clutch operation detection switch 75 is activated and the rotation of the water faucet device 14 is stopped.

As described above, according to the second embodiment, the first sensor 81 and the second sensor 82 are provided at the tip of the water discharge unit 10, which improves the visibility of both sensors 81, 82 and increases convenience for the user.

When manually rotating the water outlet, the tip of the water outlet is usually the object of operation, but according to the second embodiment, a non-contact sensor (sensors 81, 82) that is the object of operation is provided at the tip of the water outlet 10. This makes it possible to intuitively rotate the water outlet 10a by performing operations similar to those performed manually, further improving convenience.

In addition, when the sensors 81, 82, which are arranged on the left and right sides as seen from the user, detect a moving object Do to be detected, the water outlet 10a can be rotated in a direction corresponding to the direction of movement of the object Do. Therefore, the water outlet 10a can be rotated with the same feel as when the user holds the water outlet unit 10 in his or her hand and rotates it. This further increases convenience for the user.

In addition, the water outlet 10a will not rotate if the object Do is simply detected by one of the two sensors 81, 82. Furthermore, the water outlet 10a will not rotate even if the object Do is detected simultaneously by both sensors 81, 82. This makes it more difficult for the water outlet 10a to rotate unintentionally, which also contributes to improving convenience for the user.
Third Embodiment
Next, the third embodiment will be described with a focus on the differences from the first embodiment. In the first embodiment, the rotation device 7 is configured such that when the motor 72 is not in operation, an object to be detected is brought close to the first sensor 81 or the second sensor 82, and the operation of the motor 72 is controlled to rotate the water faucet device 14 (the water outlet 10a) unless the water faucet device 14 (the water outlet 10a) is unable or difficult to rotate. In other words, when the motor 72 is not in operation, if an object to be detected is brought close to the first sensor 81 or the second sensor 82, the water faucet device 14 (the water outlet 10a) is usually configured to rotate.

In contrast, in the third embodiment, the rotation device 7 is configured to control the operation of the motor 72 to rotate the water faucet device 14 and thus the water outlet 10a when the detection of the object to be detected by the first sensor 81 or the second sensor 82 (i.e., the non-contact sensor) continues for a preset period of time or more. In other words, simply bringing the object to be detected close to the first sensor 81 or the second sensor 82 may not be enough to rotate the water faucet device 14 (water outlet 10a). In this case, in order to rotate the water faucet device 14 (water outlet 10a), it is necessary to keep the object to be detected close to the first sensor 81 or the second sensor 82 for a preset period of time or more. In this third embodiment, the control device 76 is configured as follows to switch between a state in which the water faucet device 14 (water outlet 10a) can be rotated by the detection of an object by the sensors 81 and 82 (called the "locked-on state") and a state in which the water faucet device 14 (water outlet 10a) cannot be rotated by the detection of an object by the sensors 81 and 82 (called the "unlocked-on state"), to store these states, and to perform control according to these states.

That is, as shown in FIG. 19, the control device 76 includes a lock-on state memory unit 763 and a lock-on determination unit 764.

The lock-on state storage unit 763 is configured, for example, with a RAM, and stores information indicating that the device is in a locked-on state or a non-locked-on state.

The lock-on determination unit 764 constitutes a part of the processing unit 761 (of course, it may be separate from the processing unit 761) and switches between the locked-on state and the non-locked-on state based on the first or second detection signal output from the sensors 81 and 82 and the information stored in the lock-on state storage unit 763. More specifically, the lock-on determination unit 764 determines whether the output of the first or second detection signal from the sensors 81 and 82 continues for a predetermined time (e.g., one second) or more when the motor 72 is not in operation (i.e., whether the first or second detection signal continues to be input to the control device 76 for a predetermined time or more). Then, if the output of the first or second detection signal continues for a predetermined time or more, the lock-on determination unit 764 switches (updates) the information stored in the lock-on state storage unit 763 to information indicating the non-locked-on state if the lock-on state storage unit 763 stores information indicating the locked-on state when the output of the first or second detection signal continues for a predetermined time or more. On the other hand, if information indicating a non-locked-on state is stored in the lock-on state storage unit 763, the lock-on determination unit 764 switches the information stored in the lock-on state storage unit 763 to information indicating a locked-on state.

The processing unit 761 is also configured to change its operation when a first or second detection signal is output from the sensors 81, 82, depending on the information stored in the lock-on state memory unit 763. In more detail, when the motor 72 is not operating and the lock-on state memory unit 763 stores information indicating that the motor 72 is in the locked-on state (i.e., the motor 72 is in the locked-on state), the processing unit 761 generates a first rotation command as a command to rotate the water faucet device 14 and thus the water outlet 10a in a predetermined direction when the first detection signal is output from the first sensor 81. As a result, the water outlet 10a will rotate in the predetermined direction if it is in a rotatable state.

In addition, when the motor 72 is not operating and the processing unit 761 is in the locked-on state, if a second detection signal is output from the second sensor 82, the processing unit 761 generates a second rotation command as a command to rotate the water faucet device 14 and therefore the water outlet 10a in the direction opposite to the predetermined direction. As a result, if the water outlet 10a is in a rotatable state, it will rotate in the direction opposite to the predetermined direction.

In contrast, when the motor 72 is not operating and information indicating that the motor is not locked on is stored in the lock-on state memory unit 763 (i.e., when the motor is not locked on), the processing unit 761 does not generate any special commands even if the first or second detection signal is output from the sensors 81, 82. Therefore, in the non-locked-on state, even if an object to be detected is brought close to the sensors 81, 82, the water outlet 10a does not rotate. In other words, in this third embodiment, the water outlet 10a can be rotated using the sensors 81, 82 only when the motor is locked on.

In addition, in this third embodiment, similar to the first embodiment, when the first or second detection signal is output from the sensors 81 and 82 while the motor 72 is operating, the processing unit 761 generates a rotation stop command.

Next, the normal operation of the processing unit 761 related to the rotation of the water faucet device 14 (water outlet 10a) in this third embodiment will be described with reference to the flowchart in FIG. 20 etc.

First, in step S41, it is confirmed whether the motor 72 is operating. If the motor 72 is operating (step S41: Yes), the process proceeds to step S42. If the motor 72 is not operating (step S41: No), the process proceeds to step S44. Note that the processing of steps S42 and S43 is almost the same as the processing of steps S12 and S13 in the first embodiment, and therefore a description thereof will be omitted.

If the motor 72 is not operating, in step S44, it is determined whether or not information indicating a locked-on state is stored in the lock-on state storage unit 763 (i.e., whether or not the motor 72 is in a locked-on state). If the motor 72 is in a locked-on state (step S44: Yes), the process proceeds to step S45, where processing for the locked-on state is executed, and the process returns to step S41. On the other hand, if the motor 72 is not in a locked-on state (if the motor 72 is in a non-locked-on state) (step S44: No), the process proceeds to step S46, where processing for the non-locked-on state is executed, and the process returns to step S41.

Next, the process in the locked-on state will be described with reference to FIG. 21. First, in step S51, it is confirmed whether or not a first detection signal has been output from the first sensor 81. If a first detection signal has been output (step S51: Yes), the process proceeds to step S52. On the other hand, if a first detection signal has not been output (step S51: No), the process proceeds to step S57.

In step S52, it is determined whether the first short input flag is off. The first short input flag is information indicating that the detection of the object by the first sensor 81 continued for less than the predetermined time, such as when the object approaches the first sensor 81 for an instant. If the first short input flag is off (step S52: Yes), the first short input flag is set to on in step S53, and the process proceeds to step S54. On the other hand, if the first short input flag is already set to on (step S52: No), step S53 is skipped and the process proceeds to step S54.

In step S54, it is determined whether a predetermined time has elapsed since the first short input flag was set to on. If the predetermined time has not elapsed (step S54: No), the process returns to step S51. By the processes of steps S51 and S54, it is confirmed whether the first detection signal has been output within a predetermined time since the first short input flag was set. On the other hand, if the predetermined time has elapsed (step S54: Yes), that is, if the first detection signal has been output for a predetermined time or more since the first short input flag was set to on, the first long input flag is set to on in step S55. The first long input flag is information indicating that the detection of the object by the first sensor 81 has continued for the predetermined time or more, such as when the object continues to approach the first sensor 81 for a relatively long time. After step S55, the first short input flag is reset to off in step S56, and the process proceeds to step S63.

On the other hand, if the first detection signal has not been output (step S51: No), in step S57, it is confirmed whether or not the second detection signal has been output from the second sensor 82. If the second detection signal has been output (step S57: Yes), the process proceeds to step S58. On the other hand, if the second detection signal has not been output (step S57: No), the process proceeds to step S63.

In step S58, it is determined whether the second short input flag is off. The second short input flag is information indicating that the detection of the object by the second sensor 82 continued for less than the predetermined time. If the second short input flag is off (step S58: Yes), the second short input flag is set to on in step S59, and the process proceeds to step S60. On the other hand, if the second short input flag is already set to on (step S58: No), step S59 is skipped and the process proceeds to step S60.

In step S60, it is determined whether a predetermined time has elapsed since the second short input flag was set to on. If the predetermined time has not elapsed (step S60: No), the process returns to step S57. The processes in steps S57 and S60 confirm whether the second detection signal has been output within a predetermined time since the second short input flag was set. On the other hand, if the predetermined time has elapsed (step S60: Yes), that is, if the second detection signal has been output for a predetermined time or more since the second short input flag was set to on, the second long input flag is set to on in step S61. The second long input flag is information indicating that the detection of the object by the second sensor 82 has continued for the predetermined time or more. After step S61, the second short input flag is reset to off in step S62, and the process proceeds to step S63.

In step S63, it is determined whether the first short input flag is on. If the first short input flag is on (step S63: Yes), a first rotation command is generated in step S64, and the process proceeds to step S69. By generating the first rotation command, the water faucet device 14 and the water outlet 10a rotate in a predetermined direction.

On the other hand, if the first short input flag is off (step S63: No), in step S65, it is determined whether the second short input flag is on. If the second short input flag is on (step S65: Yes), in step S66, a second rotation command is generated, and the process proceeds to step S69. By generating the second rotation command, the water faucet device 14 and therefore the water outlet 10a rotate in the direction opposite to the predetermined direction.

Furthermore, if the second short input flag is off (step S65: No), in step S67, it is determined whether the first long input flag or the second long input flag is on. If the first long input flag or the second long input flag is on (step S67: Yes), in step S68, the information stored in the lock-on state storage unit 763 is switched to information indicating a non-lock-on state, and the process proceeds to step S69. On the other hand, if both long input flags are off (step S67: No), the process in the lock-on state is terminated without switching the information.

Then, in step S69, the various flags set during the lock-on state processing (such as the first short input flag) are turned off, and the lock-on state processing ends.

Next, the processing in the non-locked-on state will be described with reference to FIG. 22. First, in step S71, it is confirmed whether or not a first detection signal has been output from the first sensor 81. If a first detection signal has been output (step S71: Yes), the process proceeds to step S72. On the other hand, if a first detection signal has not been output (step S71: No), the process proceeds to step S74.

In step S72, it is determined whether a predetermined time has elapsed since the initial first detection signal was output in this non-lock-on state processing. If the predetermined time has not elapsed (step S72: No), the process returns to step S71. The processes of steps S71 and S72 confirm whether the first detection signal has continued to be output within a predetermined time since the initial first detection signal was output. Then, if the predetermined time has elapsed (step S72: Yes), that is, if the first detection signal has continued to be output for a predetermined time or longer, in step S73, the first long input flag is set to ON, and the process proceeds to step S77.

On the other hand, if the first detection signal has not been output (step S71: No), in step S74, it is confirmed whether or not the second detection signal has been output from the second sensor 82. If the second detection signal has been output (step S74: Yes), the process proceeds to step S75. On the other hand, if the second detection signal has not been output (step S74: No), the process proceeds to step S77.

In step S75, it is determined whether a predetermined time has elapsed since the first second detection signal was output in this non-lock-on state processing. If the predetermined time has not elapsed (step S75: No), the process returns to step S74. The processes in steps S74 and S75 confirm whether the second detection signal has continued to be output within a predetermined time since the first second detection signal was output. If the predetermined time has elapsed (step S75: Yes), that is, if the second detection signal has continued to be output for a predetermined time or longer, in step S76, the second long input flag is set to ON, and the process proceeds to step S77.

In step S77, it is determined whether the first long input flag or the second long input flag is on. If the first long input flag or the second long input flag is on (step S77: Yes), in step S78, the information stored in the lock-on state storage unit 763 is switched to information indicating a locked-on state, and the process proceeds to step S79. On the other hand, if both long input flags are off (step S77: No), the process ends without switching the information when the non-locked-on state occurs.

Then, in step S79, the non-lock-on state processing is terminated by turning off each flag (such as the first long input flag) that was set during the non-lock-on state processing.

The water faucet system 1 according to the third embodiment configured as described above operates as follows when operated by the user. That is, in the locked-on state, as in the first embodiment, when the water faucet device 14 is stopped and the object to be detected Do is brought close to the first sensor 81 or the second sensor 82 for less than a predetermined time, the water faucet device 14 and the water outlet 10a rotate in a predetermined direction or in a direction opposite to the predetermined direction, as shown in FIG. 23. Also, when the object to be detected Do is brought close to the first sensor 81 or the second sensor 82 again while the water faucet device 14 is rotating, the rotation of the water faucet device 14 and the water outlet 10a is stopped.

In contrast, in this third embodiment, as shown in FIG. 24, when the device is in the unlocked state, the faucet device 14 (water outlet 10a) does not rotate even if the object to be detected Do is brought close to the first sensor 81 or the second sensor 82 for less than a predetermined time.

Also, as shown in FIG. 25, if the detected object Do continues to approach the first sensor 81 or the second sensor 82 for a predetermined period of time or longer while the faucet device 14 is stopped, the locked-on state is switched to the non-locked-on state, and the non-locked-on state is switched to the locked-on state.

As described above, according to the third embodiment, when the non-contact type sensor (sensors 81, 82) continues to detect the object Do for a predetermined time or more, the rotation device 7 enters a state (locked-on state) in which the operation of the motor 72 for rotating the water faucet device 14 (water outlet 10a) can be controlled. In other words, it is only when the non-contact type sensor (sensors 81, 82) continues to detect the object Do for a predetermined time or more that the rotation device 7 enters a state in which control for rotating the water faucet device 14 (water outlet 10a) can be performed. Therefore, it is possible to make it even more difficult for the water outlet 10a to rotate unintentionally, and to further improve convenience.
Fourth Embodiment
Next, the fourth embodiment will be described focusing on the differences from the first embodiment. In the first embodiment, a water discharge/stop sensor 5 is provided to switch water discharge or water stop at the water outlet 10a. In contrast, in the fourth embodiment, as shown in FIG. 26, the water discharge/stop sensor 5 is not provided, and the first sensor 81 and the second sensor 82 are configured to also function as the water discharge/stop sensor 5.

In this fourth embodiment, the rotation device 7 is configured to selectively control the operation of the motor 72 or the solenoid valve 6 when the first detection signal or the second detection signal is output, so that the sensors 81, 82 also function as the water discharge/stop sensor 5. In more detail, the control device 76 in this fourth embodiment includes a mode storage unit 765, a mode switching unit 766, and a solenoid valve control unit 767, as shown in FIG. 27. In this embodiment, the mode switching unit 766 corresponds to the "switching means."

The mode memory unit 765 stores information indicating the target of operational control when the first or second detection signal is output. The mode memory unit 765 is configured, for example, with a RAM, and stores information indicating the rotation control mode or the water discharge/stop control mode. The rotation control mode is a state in which the operation of the motor 72 can be controlled (i.e., the motor 72 is the target of operational control) when the first or second detection signal is output from the sensors 81, 82. On the other hand, the water discharge/stop control mode is a state in which the operation of the solenoid valve 6 can be controlled (i.e., the solenoid valve 6 is the target of operational control) when the first or second detection signal is output from the sensors 81, 82.

The mode switching unit 766 constitutes a part of the processing unit 761 (of course, it may be separate from the processing unit 761) and switches between the rotation control mode and the water discharge/stop control mode based on the first or second detection signal output from the sensors 81, 82 and the information stored in the mode memory unit 765. More specifically, the mode switching unit 766 determines whether the output of the first or second detection signal from the sensors 81, 82 continues for a predetermined time (e.g., one second) or more when the motor 72 is not in operation. Then, if the output of the first or second detection signal continues for a predetermined time or more, and if information indicating the rotation control mode is stored in the mode memory unit 765, the mode switching unit 766 switches (updates) the information stored in the mode memory unit 765 to information indicating the water discharge/stop control mode. On the other hand, when information indicating that the mode is the water discharge/stop control mode is stored in the mode memory unit 765, the mode switching unit 766 switches the information stored in the mode memory unit 765 to information indicating that the mode is the rotation control mode.

Next, before describing the solenoid valve control unit 767, the processing unit 761 in this fourth embodiment will be described. As in the first embodiment, the processing unit 761 performs calculations based on the input signals and generates commands according to the calculation results, but in this fourth embodiment, the generated commands are changed depending on the information related to the mode stored in the mode storage unit 765.

In more detail, when the motor 72 is not operating and the mode memory unit 765 stores information indicating that the mode is the rotation control mode (when the mode is the rotation control mode), the processing unit 761 generates a first rotation command when the first detection signal is output from the first sensor 81 for less than a predetermined time. Also, when the motor 72 is not operating and the mode is the rotation control mode, the processing unit 761 generates a second rotation command when the second detection signal is output from the second sensor 82 for less than a predetermined time. When the first rotation command or the second rotation command is generated, the motor control unit 762 controls the operation of the motor 72, and the water faucet device 14 and therefore the water outlet 10a rotate. Therefore, in the rotation control mode, the first sensors 81 and 82 are used to operate the rotation of the water faucet device 14 (water outlet 10a).

On the other hand, when the motor 72 is not operating and the mode memory unit 765 stores information indicating that the mode is the water discharge/stop control mode (i.e., when the mode is the water discharge/stop control mode), if the first detection signal is output from the first sensor 81 for less than a predetermined time, the processing unit 761 generates a water discharge command as a command to discharge water from the water outlet 10a. Also, when the motor 72 is not operating and the mode is the water discharge/stop control mode, if the second detection signal is output from the second sensor 82 for less than a predetermined time, the processing unit 761 generates a water stop command as a command to stop water at the water outlet 10a.

The solenoid valve control unit 767 controls the operation of the solenoid valve 6 to switch between water discharge and water stop at the water outlet 10a. In detail, when a water discharge command is generated by the processing unit 761 (i.e., when a first detection signal is output from the first sensor 81 in the water discharge/stop control mode), the solenoid valve control unit 767 controls the operation of the solenoid valve 6 so that water is discharged from the water outlet 10a. On the other hand, when a water stop command is generated by the processing unit 761 (i.e., when a second detection signal is output from the second sensor 82 in the water discharge/stop control mode), the solenoid valve control unit 767 controls the operation of the solenoid valve 6 so that water is stopped at the water outlet 10a. Note that if a water discharge command is generated when water is already being discharged at the water outlet 10a, or if a water stop command is generated when water is already stopped at the water outlet 10a, the solenoid valve control unit 767 maintains the solenoid valve 6 in its current state.

As described above, in the fourth embodiment, in the water discharge/stop control mode, the sensors 81 and 82 are used to switch between water discharge and water stop at the water outlet 10a. Also, in the first embodiment, the water discharge/stop sensor 5 is a common operation target for both water discharge and water stop at the water outlet 10a, but in the fourth embodiment, the first sensor 81 is a dedicated operation target for water discharge at the water outlet 10a, and the second sensor 82 is a dedicated operation target for water stop at the water outlet 10a.

Next, the rotation of the water faucet device 14 (water outlet 10a) and the normal operation of the processing unit 761 related to discharging or stopping water at the water outlet 10a in this fourth embodiment will be described with reference to the flowchart in FIG. 28 etc.

First, in step S81, it is confirmed whether the motor 72 is operating. If the motor 72 is operating (step S81: Yes), the process proceeds to step S82. If the motor 72 is not operating (step S81: No), the process proceeds to step S84. Note that the processing of steps S82 and S83 is almost the same as the processing of steps S12 and S13 in the first embodiment, and therefore a description thereof will be omitted.

If the motor 72 is not operating, in step S84, it is determined whether or not information indicating that the mode is the rotation control mode is stored in the mode memory unit 765 (i.e., whether or not the mode is the rotation control mode). If the mode is the rotation control mode (step S84: Yes), the process proceeds to step S85, where the rotation control mode processing is executed, and the process returns to step S81. On the other hand, if the mode is not the rotation control mode (i.e., if the mode is the water discharge/stop control mode) (step S84: No), the process proceeds to step S86, where the water discharge/stop control mode processing is executed, and the process returns to step S81.

In the rotation control mode process, the process shown in FIG. 29 is performed. The processes in steps S91 to S107 and S109 performed in the rotation control mode process are almost the same as the processes in steps S51 to S67 and S69 in the locked-on state process in the third embodiment, so a description of them will be omitted.

In addition, in the rotation control mode processing, if the first long input flag or the second long input flag is on (step S107: Yes), in step S108, the information stored in the mode memory unit 765 is switched to information indicating the water discharge/stop control mode. With this processing, if the output of the first detection signal or the second detection signal from the sensors 81, 82 continues for a predetermined time or more in the rotation control mode, the rotation control mode is switched to the water discharge/stop control mode.

Next, the process in the water discharge/stop control mode will be described. In the water discharge/stop control mode, the process shown in FIG. 30 is performed. The processes in steps S111 to S123, 125, 127, and 129 performed in the rotation control mode are almost the same as the processes in steps S91 to S103, 105, 107, and 109 in the rotation control mode, so their description will be omitted.

In addition, in the water discharge/stop control mode process, if the first short input flag is on (step S123: Yes), a water discharge command is generated in step S124. The generation of the water discharge command causes water to be discharged from the water discharge port 10a.

Furthermore, in the water discharge/stop control mode processing, if the second short input flag is on (step S125: Yes), a water stop command is generated in step S126. The generation of the water stop command stops the water supply at the water discharge port 10a.

In addition, in the water discharge/stop control mode processing, if the first long input flag or the second long input flag is on (step S127: Yes), in step S128, the information stored in the mode memory unit 765 is switched to information indicating the rotation control mode. With this processing, in the water discharge/stop control mode, if the output of the first detection signal or the second detection signal from the sensors 81, 82 continues for a predetermined time or more, the water discharge/stop control mode is switched to the rotation control mode.

The faucet system 1 according to the fourth embodiment configured as described above operates as follows when operated by the user. That is, in the rotation control mode, as in the first embodiment, when the faucet device 14 (water outlet 10a) is stopped, if the detected object Do approaches the first sensor 81 or the second sensor 82 for less than a predetermined time, the faucet device 14 and the water outlet 10a rotate in a predetermined direction or in a direction opposite to the predetermined direction. Also, if the detected object Do is brought close to the first sensor 81 or the second sensor 82 again while the faucet device 14 (water outlet 10a) is rotating, the rotation of the faucet device 14 and the water outlet 10a is stopped.

In contrast, in this fourth embodiment, in the water discharge/stop control mode, as shown in Figures 31 and 32, when the object to be detected Do is brought close to the first sensor 81 for less than a predetermined time, water is discharged from the water outlet 10a, and when the object to be detected Do is brought close to the second sensor 82 for less than a predetermined time, water is stopped from the water outlet 10a.

In addition, when the faucet device 14 (water outlet 10a) is stopped, if the detected object Do continues to approach the first sensor 81 or the second sensor 82 for a predetermined period of time or more, the rotation control mode is switched to the water discharge/stop control mode, and the water discharge/stop control mode is switched to the rotation control mode.

As described above, according to the fourth embodiment, the mode switching unit 766 can switch between the rotation control mode and the water discharge/stop control mode, and the object to be controlled in response to the output of the first detection signal or the second detection signal can be switched between the motor 72 and the solenoid valve 6. Therefore, the operation related to the rotation of the faucet device 14 (water outlet 10a) and the operation related to the water discharge/stop at the water outlet 10a can be performed using a common non-contact sensor (sensors 81, 82). This makes it unnecessary to provide a water discharge/stop sensor 5 for discharging and stopping water separately from the non-contact sensor, and simplifies the faucet system 1. As a result, it is possible to reduce the costs associated with the manufacture and maintenance of the faucet system 1.

Furthermore, in the fourth embodiment, in the water discharge/stop control mode, the first sensor 81 is used for water discharge, and the second sensor 82 is used for water stop. Therefore, since the roles of the two sensors 81, 82 in the water discharge/stop control mode are clearly divided, operations related to water discharge/stop can be performed more easily and intuitively, and convenience for the user can be further improved.
Fifth Embodiment
Next, the fifth embodiment will be described, focusing on the differences from the first embodiment. In the first embodiment, the operation unit 8 is composed of non-contact sensors (first sensor 81 and second sensor 82). In contrast, in the fifth embodiment, as shown in Figures 33 and 34, a first foot switch 15 and a second foot switch 16 are provided as the operation unit, and these foot switches 15, 16 allow the user to operate the motor 72 and the water outlet 10a using parts of the body other than the hands (basically the feet).

The foot switches 15, 16 are arranged on the left and right sides as seen from the user, for example, on the front of the legs of the base 102. Each foot switch 15, 16 has a pressable part that is the object of the pressing operation, and a signal output part (not shown) that outputs a predetermined detection signal when the pressable part is pressed. When the pressable part is pressed, each foot switch 15, 16 outputs a detection signal from the signal output part. The output detection signal is input to the control device 76 via a predetermined signal line (not shown). In this fifth embodiment, the first foot switch 15 corresponds to the first sensor 81 in the first embodiment, and is capable of outputting a first detection signal as a detection signal. On the other hand, the second foot switch 16 corresponds to the second sensor 82 in the first embodiment, and is capable of outputting a second detection signal as a detection signal.

The faucet system 1 according to the fifth embodiment configured as described above operates as follows when operated by the user. That is, when the user operates the first foot switch 15 (presses the pressable portion) while the faucet device 14 (water outlet 10a) is stopped, the faucet device 14 and therefore the water outlet 10a rotate in a predetermined direction. On the other hand, when the user operates the second foot switch 16 while the faucet device 14 (water outlet 10a) is stopped, the faucet device 14 and therefore the water outlet 10a rotate in the opposite direction to the predetermined direction.

Then, if the first foot switch 15 or the second foot switch 16 is operated again while the faucet device 14 (water outlet 10a) is rotating, the rotation of the faucet device 14 (water outlet 10a) will be stopped. Even if the first foot switch 15 or the second foot switch 16 is not operated while the faucet device 14 (water outlet 10a) is rotating, if the faucet device 14 reaches the limit of its rotational range, the clutch operation detection switch 75 will operate and the rotation of the faucet device 14 (water outlet 10a) will be stopped.

As described above, according to the fifth embodiment, the operation unit is composed of the foot switches 15, 16 that can be operated by parts of the user other than the hands. Therefore, the faucet device 14 and the water outlet 10a can be rotated while the hands are free to use, which increases convenience for the user.
Sixth Embodiment
Next, the sixth embodiment will be described, focusing on the differences from the first embodiment. In the first embodiment, the faucet body 9 (the outer first tubular portion 31 and the inner first tubular portion 41) is provided in a state in which it passes through the top plate portion 101b through the mounting hole 101c. In contrast, in the sixth embodiment, as shown in FIG. 35, the faucet body 9 does not pass through the top plate portion 101b, and the entire faucet body 9 is arranged in the front space 104.

In addition, in FIG. 35, the faucet body 9 is shown in a simplified form, but the faucet body 9 in this sixth embodiment has an outer first tubular portion 31 and an inner first tubular portion 41, as in the first embodiment. In addition, in this sixth embodiment, a water supply pipe w, a hot water supply pipe h, a water conduit c, a cable k (lead wire), etc. (each shown in a simplified form in FIG. 35) are provided below or inside the faucet body 9. The water or hot water supplied from each pipe w, h is configured to flow into the water conduit c, and an electromagnetic valve 6 is interposed in the water conduit c. The part of the water conduit c downstream of the electromagnetic valve 6 constitutes the inner component 4 (not shown in FIG. 35), and water is discharged from the water outlet 10a (not shown in FIG. 35) located at the tip side of that part (inner component 4). The cable k includes one that transmits the output signals from the sensors 81 and 82 to the control device 76, and one that transmits the output signal from the water discharge/stop sensor 5 to the solenoid valve 6.

Now, to explain the faucet system 1 in the sixth embodiment in more detail, the faucet system 1 includes a base portion 20 interposed between the holding tube portion 2 and the faucet main body portion 9. In FIG. 35, the base portion 20 is shown in a simplified form. The base portion 20 includes a device connecting portion 20a that protrudes downward, and is fixed to the holding tube portion 2 with the device connecting portion 20a inserted into a hole portion 101d formed through the top plate portion 101b. As a result, the base portion 20 is installed in a state where it cannot rotate relative to the sink 101 (top plate portion 101b).

The holding tube portion 2 in this sixth embodiment is not directly attached to the rotating device 7, does not have a male thread portion 22, and is fixed to the sink 101 (top plate portion 101) by an attachment structure not shown. In this sixth embodiment, the above-mentioned water supply pipe w, hot water supply pipe h, water guide pipe c, cable k, etc. are inserted and installed inside the holding tube portion 2.

When the base 20 is fixed to the retaining tube 2, it has a main body insertion hole 20b that communicates with the internal space of the retaining tube 2 and extends vertically, and a transmission part insertion hole 20c that penetrates the device connection part 20a. The faucet main body 9 is inserted into the upper part of the main body insertion hole 20b, so that it does not penetrate the top plate 101b and is entirely located in the front space 104. A specified packing (not shown), such as an X-ring, is placed between the base 20 and the faucet main body 9 to prevent water from entering between them.

In addition, in this sixth embodiment, in addition to the water discharge/stop sensor 5 (not shown in FIG. 35), a lever portion 13 is provided on the upper portion of the base portion 20 on the water storage portion 101a side. By operating the lever portion 13, it is possible to switch between a water discharge enabled state and a water discharge disabled state at the water outlet 10a, and to adjust the amount of water discharged from the water outlet 10a and the water temperature. In this sixth embodiment, when the lever portion 13 is operated to set the water discharge enabled state, water can be discharged from the water outlet 10a using the water discharge/stop sensor 5.

In the sixth embodiment, the transmission part 73 of the rotation device 7 includes a first intermediate transmission part 732, a second intermediate transmission part 733, and a spout side transmission part 734, and the spout side transmission part 734 is disposed in the front space 104 in response to the faucet main body 9 being disposed in the front space 104. The transmission part 73 in the sixth embodiment includes a third intermediate transmission part 735 for transmitting a driving force from the second intermediate transmission part 733 located in the back space 105 to the spout side transmission part 734 located in the front space 104. The third intermediate transmission part 735 includes a rod-shaped longitudinal transmission part 735a, a one-end side transmission part 735b provided at one end of the longitudinal transmission part 735a, and an other-end side transmission part 735c provided at the other end of the longitudinal transmission part 735a.

The longitudinal transmission part 735a is rotatably inserted into the transmission part insertion hole 20c, and transmits the driving force generated by the operation of the motor 72 from the rear space 105 to the front space 104 through the hole 101d. The one-end transmission part 735b is rotatable together with the longitudinal transmission part 735a, and a gear provided on its outer periphery is meshed with the spout side transmission part 734 (driven gear 734a). The other-end transmission part 735c is rotatable together with the longitudinal transmission part 735a, and a gear provided on its outer periphery is meshed with the second intermediate transmission part 733 (drive gear 733b).

In addition, in this sixth embodiment, the motor side transmission part 731 is integrated with the first intermediate transmission part 732. In addition, a male screw 714 is fixed to the first intermediate transmission part 732, and a pressing part 74 is sandwiched between the head part of the male screw 714 and the second intermediate transmission part 733, so that the second intermediate transmission part 733 is pressed against the first intermediate transmission part 732.

In the faucet system 1 of the sixth embodiment configured as described above, the motor 72 is operated by operating the operation unit 8 (sensors 81, 82), and the driving force caused by the operation of the motor 72 is transmitted to the portion of the faucet main body 9 located in the front space 104 via the third intermediate transmission unit 735 (longitudinal transmission unit 735a, etc.). As a result, the faucet device 14 and therefore the water outlet 10a rotate, similar to the first embodiment described above.

As described above, according to the sixth embodiment, basically, the same action and effect as the first embodiment is achieved. In addition, since the driving force is transmitted to the part of the faucet body 9 located in the front space 104 via the vertical transmission part 735a, it is not necessary to use a faucet body 9 that penetrates the sink 101 (top plate part 101b). This allows the faucet body 9 to be made smaller (lighter), and the smoothness of the rotation of the faucet body 9 and the spout 10a can be improved. In addition, a larger installation space can be secured below the faucet body 9 for the water supply pipe w, hot water supply pipe h, water supply pipe c, etc. As a result, it becomes easier to naturally exert the desired function of the faucet device 14, and the ease of installation of the faucet device 14 (faucet system 1) can be improved.
Seventh Embodiment
Next, the seventh embodiment will be described, focusing on the differences from the first embodiment. In the first embodiment, the rotation device 7 does not have a function to automatically change the position of the water outlet 10a in the rotation direction over time, and is configured to maintain the position of the water outlet 10a after the water faucet device 14 (water outlet 10a) rotates. In contrast, in the seventh embodiment, the rotation device 7 is configured to be able to control the operation of the motor 72 so that the water outlet 10a returns to a predetermined set position when the sensors 81, 82 do not detect an object for a predetermined period of time or more.

In more detail, in the seventh embodiment, the rotation device 7 is equipped with a position detection device 79 as shown in FIG. 36. The position detection device 79 is provided in a portion of the faucet main body 9 or the transmission unit 73 that (always) rotates with the rotation of the water outlet 10a (for example, the second intermediate transmission unit 733, etc.), and is composed of an encoder (not shown) that can detect the rotation angle of the faucet main body 9 or the portion. The position detection device 79 is used to determine whether the water outlet 10a is located at the set position, whether the water outlet 10a is located to the left or right of the set position as seen by the user, and whether the water outlet 10a has rotated. The position detection device 79 can output a signal (information) regarding the rotation angle of the water outlet 10a to the motor control unit 762.

The motor control unit 762 also sends information about the rotation angle of the water outlet 10a to the processing unit 761 based on the output signal from the position detection device 79. This allows the processing unit 761 to grasp the position of the water outlet 10a in the rotation direction.

Furthermore, when the processing unit 761 determines that the water outlet 10a has rotated based on the output signal from the position detection device 79, it starts measuring time. The time measurement can be performed using a specified timer. Then, when the measured time exceeds a predetermined time (e.g., 30 minutes) while the water outlet 10a is placed in a position other than the set position, the processing unit 761 performs processing to return the water outlet 10a to the set position.

That is, the processing unit 761 detects whether the water outlet 10a is located to the left or right of the set position as seen by the user, based on the output signal from the position detection device 79. Then, the processing unit 761 generates a first rotation command or a second rotation command based on the detected position of the water outlet 10a. That is, the processing unit 761 generates a first rotation command when the water outlet 10a is located to the left of the set position as seen by the user. On the other hand, the processing unit 761 generates a second rotation command when the water outlet 10a is located to the right of the set position as seen by the user. By generating the first rotation command or the second rotation command, the motor control unit 762 controls the supply of electricity to the motor 72, and the water faucet device 14 and therefore the water outlet 10a rotate back to the set position.

Furthermore, after generating the first rotation command or the second rotation command, the processing unit 761 generates a rotation stop command when it determines that the water outlet 10a has been placed in the set position based on the output signal from the position detection device 79. With the generation of the rotation stop command, the motor control unit 762 stops the supply of electricity to the motor 72. As a result, the water outlet 10a is placed (returned) to the set position.

The "set position" of the water outlet 10a may be, for example, a position at the center of the rotational range of the water outlet 10a or a position at the edge of the rotational range, but is not limited to these and may be a fixed, pre-set position within the rotational range of the water outlet 10a.

Next, the normal operation of the processing unit 761 related to the rotation of the water faucet device 14 (water outlet 10a) in this seventh embodiment will be described with reference to the flowchart in FIG. 37. Note that the processing of steps S11 to S17 is basically the same as in the first embodiment, so a description of these processes will be omitted.

In the seventh embodiment, if the motor 72 is not operating and both the first and second detection signals are not being output, that is, if a negative judgment is made in step S16, the process proceeds to steps S18 and S19, where counting processing and setting position arrangement processing are performed.

The counting process is a process for measuring the elapsed time from the most recent rotation of the faucet device 14 (water outlet 10a). In the counting process, as shown in FIG. 38, first, in step S18-1, the output signal from the position detection device 79 is used to determine whether or not the faucet device 14 (water outlet 10a) has rotated. This determination is made by comparing the rotation angle determined by the output from the position detection device 79 in the previous step S18-1 with the rotation angle similarly determined in the current step S18-1, and if there is a difference between these, it is determined that the faucet device 14 (water outlet 10a) has rotated. If the faucet device 14 (water outlet 10a) has rotated (step S18-1: Yes), the process proceeds to step S18-2. If the faucet device 14 (water outlet 10a) has not rotated (step S18-1: No), the counting process ends and the process proceeds to the setting position arrangement process in step S19.

In step S18-2, a time measurement reset process is performed. That is, the time measurement is stopped and the measured time is reset to an initial value (for example, 0). This process is performed in order to re-measure the time when the faucet device 14 (spout 10a) is rotated again during time measurement. In step S18-3 following step S18-2, a time measurement start process is performed. In the time measurement start process, time measurement is started. After step S18-3, the setting position arrangement process of step S19 is performed.

The set position arrangement process is a process for placing the spout 10a at the set position. In the set position arrangement process, as shown in FIG. 39, first, in step S19-1, it is determined whether the conditions for performing the processes in step S19-2 and subsequent steps in the set position arrangement process are met. In the seventh embodiment, in step S19-1, it is determined whether the measured time in the counting process has exceeded a preset predetermined time. If the measured time has not exceeded the predetermined time (step S19-1: No), the set position arrangement process ends and returns to step S11. On the other hand, if the measured time has exceeded the predetermined time (step S19-1: Yes), the process proceeds to step S19-2. Note that if time measurement has not been performed, the measured time is set to an initial value, and a negative determination is made in step S19-1.

In step S19-2, the output signal from the position detector 79 is used to determine whether the water outlet 10a is located at the set position. If the water outlet 10a is located at the set position (step S19-2: Yes), there is no need to rotate the water faucet device 14 (water outlet 10a), so steps S19-3 to S19-7 are skipped and the process moves to step S19-8. On the other hand, if the water outlet 10a is not located at the set position (step S19-2: No), in step S19-3, the output signal from the position detector 79 is used to determine whether the water outlet 10a is located to the left of the set position as viewed by the user.

If the water outlet 10a is located to the left of the set position as seen by the user (step S19-3: Yes), a first rotation command is generated in step S19-4. On the other hand, if the water outlet 10a is located to the right of the set position as seen by the user (step S19-3: No), a second rotation command is generated in step S19-5. By generating the first rotation command or the second rotation command, the water faucet device 14 and therefore the water outlet 10a rotate towards the set position.

After steps S19-4 and S19-5, in step S19-6, the output signal from the position detection device 79 is used to repeatedly determine whether the water outlet 10a has been placed at the set position until the water outlet 10a is placed at the set position. Then, when the water outlet 10a is placed at the set position (step S19-6: Yes), a rotation stop command is generated in step S19-7. This stops the water outlet 10a at the set position.

In step S19-8 following step S19-7, a reset process is performed on the information used to determine whether or not to perform the processes in step S19-2 and subsequent steps. In the seventh embodiment, in the reset process, a time measurement reset process similar to that in step S18-2 is performed, and the measured time is reset to an initial value (e.g., 0). After step S18-7, the process returns to step S11.

The faucet system 1 according to the seventh embodiment configured as described above operates as follows. That is, as in the first embodiment, when a detected object is brought close to the first sensor 81 or the second sensor 82 while the faucet device 14 (water outlet 10a) is stopped, the faucet device 14 and therefore the water outlet 10a rotate in a specified direction or in a direction opposite to the specified direction. Also, when a detected object is brought close to the first sensor 81 or the second sensor 82 again while the faucet device 14 (water outlet 10a) is rotating, the rotation of the faucet device 14 and therefore the water outlet 10a is stopped.

On the other hand, if the water faucet device 14 (water outlet 10a) has been rotated to a position other than the set position, when a predetermined time (e.g., 30 minutes) has elapsed since the most recent rotation of the water faucet device 14 (water outlet 10a), the water outlet 10a will automatically rotate to the set position.

As described above, the seventh embodiment basically achieves the same effects as the first embodiment.

In addition, according to the seventh embodiment, when no operation is performed on the operating unit 8 (detection of an object by the sensors 81, 82) for a predetermined period of time or more, the water outlet 10a can be automatically rotated and placed (returned) to a predetermined set position. Therefore, the water outlet 10a can be returned to the set position without touching the water faucet device 14, further improving convenience.

In addition, the water outlet 10a is basically placed in the set position (unless it has been rotated recently), and the state in which the water outlet 10a is placed in the set position is the normal state for the user. Therefore, when the water faucet system 1 is used after a certain amount of time has passed since the water outlet 10a was rotated, the position of the water outlet 10a is unlikely to differ from the normal state (because the water outlet 10a automatically returns to the set position). This further improves convenience for the user.
Eighth embodiment
Next, the eighth embodiment will be described, focusing on the differences from the seventh embodiment. In the seventh embodiment, the rotating device 7 is configured to be able to control the operation of the motor 72 so that the water outlet 10a returns to a predetermined set position when the sensors 81, 82 do not detect an object for a predetermined period of time or more. In contrast, in the eighth embodiment, the rotating device 7 is configured to be able to control the operation of the motor 72 so that the water outlet 10a returns to a predetermined set position when the sensors 81, 82 detect an object in a predetermined manner.

In more detail, similar to the seventh embodiment described above, the processing unit 761 is capable of determining, based on the output signal from the position detection device 79, whether the water outlet 10a is located at the set position, and whether the water outlet 10a is located to the left or right of the set position as viewed by the user.

The processing unit 761 basically generates a first rotation command when the first sensor 81 outputs a first detection signal while the motor 72 is not operating, and generates a second rotation command when the second sensor 82 outputs a second detection signal. However, if the output of the first or second detection signal continues for a predetermined time or more, the processing unit 761 executes a process to return the water outlet 10a to the set position. That is, in this eighth embodiment, "when the detection of the object to be detected by the first sensor 81 or the second sensor 82 continues for a predetermined time or more" corresponds to "when the detection of the object to be detected by the sensors 81 and 82 is performed in a predetermined manner that has been set in advance." Note that the "predetermined manner" can be changed as appropriate. For example, "when the detection of the object to be detected by the first sensor 81 or the second sensor 82 is performed a predetermined number of times or more within a predetermined time" or "when the first sensor 81 and the second sensor 82 are caused to detect the object to be detected in a certain procedure" may correspond to "when the detection of the object to be detected by the sensors 81 and 82 is performed in a predetermined manner that has been set in advance."

Next, the normal operation of the processing unit 761 related to the rotation of the water faucet device 14 (water outlet 10a) in this eighth embodiment will be described with reference to the flowchart in FIG. 40. Note that the processes in steps S11 to S14 and S16 are basically the same as those in the first embodiment, so the description of these processes will be omitted.

In the eighth embodiment, as shown in FIG. 40, if the first detection signal is output when the motor 72 is not operating, i.e., if the result of the determination in step S14 is positive, processing is performed in response to the first detection signal in step S150. On the other hand, if the second detection signal is output when the motor 72 is not operating, i.e., if the result of the determination in step S16 is positive, processing is performed in response to the second detection signal in step S160.

In the first detection signal response process, as shown in FIG. 41, first, in step S150-1, the first short input flag is set to ON. As in the third embodiment, the first short input flag is information indicating that the detection of the object by the first sensor 81 continued for less than the predetermined time, such as when the object approaches the first sensor 81 for an instant.

In steps S150-2 and S150-3 following step S150-1, it is determined whether the output of the first detection signal has continued for a predetermined time or more. If the output of the first detection signal has continued for a predetermined time or more (step S150-2: Yes), in steps S150-4 and S150-5, the first long input flag is changed from OFF to ON, and the first short input flag is turned OFF. As in the third embodiment, the first long input flag is information indicating that the detection of the object by the first sensor 81 has continued for the predetermined time or more, such as when the object continues to approach the first sensor 81 for a relatively long time. After the processing of step S150-5, the process proceeds to step S150-6.

On the other hand, if the output of the first detection signal is not performed continuously for a predetermined period of time or longer, i.e., if the first sensor 81 detects the object for only a relatively short period of time (step S150-3: No), the first long input flag is turned off and the first short input flag is turned on, and the process proceeds to step S150-6.

In steps S150-6 to S150-9, processing is performed according to the state (on or off) of the first short input flag and the first long input flag. That is, if the first short input flag is on (step S150-6: Yes), a first rotation command is generated in step S150-7, and the first short input flag is turned off in step S150-8, ending the first detection signal response processing. By generating the first rotation command, the water faucet device 14 and therefore the water outlet 10a rotate in the specified direction.

On the other hand, if the first short input flag is off (step S150-6), that is, if the first long input flag is on, a setting position arrangement process is performed in step S150-9, and the first detection signal response process is terminated. This setting position arrangement process is basically the same as the setting position arrangement process in the seventh embodiment. However, in this eighth embodiment, in step S19-1, a determination is made as to whether the conditions for performing the processes in step S19-2 and subsequent steps are met as to whether the first long input flag is on, and if the first long input flag is on, the process proceeds to step S19-2. Also, in the reset process in step S19-8, a process is performed to turn off the first long input flag.

Next, the second detection signal response process will be described. In this process, as shown in FIG. 42, first, in step S160-1, the second short input flag is set to ON. As in the third embodiment, the second short input flag is information indicating that the detection of the object by the second sensor 82 continued for less than the predetermined time, such as when the object approaches the second sensor 82 for an instant.

In steps S160-2 and S160-3 following step S160-1, it is determined whether the output of the second detection signal has continued for a predetermined time or more. If the output of the second detection signal has continued for a predetermined time or more (step S160-2: Yes), in steps S160-4 and S160-5, the second long input flag is changed from OFF to ON, and the second short input flag is turned OFF. As in the third embodiment, the second long input flag is information indicating that the detection of the object by the second sensor 82 has continued for the predetermined time or more, such as when the object continues to approach the second sensor 82 for a relatively long time. After the processing of step S160-5, the process proceeds to step S160-6.

On the other hand, if the second detection signal is not output continuously for a predetermined period of time or longer, i.e., if the second sensor 82 detects the object for a relatively short period of time (step S160-3: No), the second long input flag is turned off and the second short input flag is turned on, and the process proceeds to step S160-6.

In steps S160-6 to S160-9, processing is performed according to the state (on or off) of the second short input flag and the second long input flag. That is, if the second short input flag is on (step S160-6: Yes), a second rotation command is generated in step S160-7, and the second short input flag is turned off in step S160-8, ending the second detection signal response processing. By generating the second rotation command, the water faucet device 14 and therefore the water outlet 10a rotate in the direction opposite to the predetermined direction.

On the other hand, if the second short input flag is off (step S160-6: No), that is, if the second long input flag is on, a setting position arrangement process is performed in step S160-9, and the second detection signal response process is terminated. This setting position arrangement process is basically the same as the setting position arrangement process in the seventh embodiment. However, in this setting position arrangement process, in step S19-1, a determination is made as to whether the second long input flag is on as a determination as to whether the conditions for performing the processes in step S19-2 and subsequent steps are met, and if the second long input flag is on, the process proceeds to step S19-2. Also, in the reset process in step S19-8, a process is performed to turn off the second long input flag.

The faucet system 1 according to the eighth embodiment configured as described above operates as follows. That is, as in the first embodiment, when the faucet device 14 (water outlet 10a) is stopped and a detected object is brought close to the first sensor 81 or the second sensor 82 for a relatively short period of time, the faucet device 14 and the water outlet 10a rotate in a specified direction or in a direction opposite to the specified direction. Also, when the detected object is brought close to the first sensor 81 or the second sensor 82 again while the faucet device 14 (water outlet 10a) is rotating, the rotation of the faucet device 14 and the water outlet 10a is stopped.

On the other hand, when the water faucet device 14 (water outlet 10a) is stopped and the water outlet 10a is positioned at a position other than the set position, if an object to be detected continues to approach the first sensor 81 or the second sensor 82 for a predetermined period of time or longer, the water outlet 10a will rotate and be positioned at the set position.

As described above, the eighth embodiment basically achieves the same effects as the first embodiment.

In addition, according to the eighth embodiment, when the operation unit 8 (sensors 81, 82) detects an object to be detected in a predetermined manner, the water outlet 10a can be automatically rotated and placed (returned) to the set position. This allows the water outlet 10a to be returned to the set position without touching the water faucet device 14, further improving convenience.

Also, unlike the seventh embodiment, there is no need to wait for time to pass until the water outlet 10a is placed (returned) to the set position, and the user can place the water outlet 10a in the set position at their convenience without touching the water faucet device 14. Therefore, in this respect as well, convenience for the user can be improved.

The technical ideas in the first to eighth embodiments may be combined as appropriate. Furthermore, the present invention is not limited to the contents of the above embodiments, and may be implemented, for example, as follows. Of course, other applications and modifications not exemplified below are also possible.

(a) In the second embodiment and others described above, the sensors 81, 82 are provided on the tip surface of the water discharger 10, but as shown in FIG. 43, the sensors 81, 82 may be provided on the side surface (top surface) of the tip of the water discharger 10.

In addition, in the first embodiment and the like, the sensors 81 and 82 are arranged on the left and right sides as viewed from the user, but the sensors 81 and 82 may be arranged above and below or front and back as viewed from the user.

(b) Although not specifically described in the above embodiment, a rotation range setting section may be provided to allow the rotation range of the faucet device 14 and thus the water outlet 10a to be set in multiple stages. For example, as shown in FIG. 44, the rotation range setting section 17 can be configured by a rotation restriction protrusion 171 protruding from the outer periphery of the faucet main body 9 (outer component 3), a plurality of insertion holes 172 formed on the upper end surface of the holding tube 2, and a rod-shaped section 173 that can be inserted into the insertion hole 172 with its upper portion protruding from the upper end surface of the holding tube 2. In this configuration, the faucet device 14 and the water outlet 10a can be rotated within a range until the rotation restriction protrusion 171 comes into contact with the rod-shaped section 173, and the rotation range of the faucet device 14 and the water outlet 10a can be set in multiple stages by adjusting the installation position of the rod-shaped section 173. This makes it easy to prevent the water faucet device 14 (water outlet 10a) from reaching an undesirable location in relation to surrounding objects, for example, and further improves convenience for users.

The rotation range setting unit 17 is based on the assumption that the clutch unit 78 and the clutch operation detection switch 75 are present. In other words, by providing the clutch unit 78 and the clutch operation detection switch 75, it is possible to set (adjust) the rotation range of the water faucet device 14 and the water outlet 10a without making any particular changes to the configuration of the rotation device 7, simply by physically limiting the rotation of the water faucet device 14 and the water outlet 10a to a certain range.

(c) In the first embodiment, the water outlet 10a is configured to rotate in a direction away from the detected object Do, but it may also rotate in a direction toward the detected object Do.

(d) In the first embodiment described above, when an object to be detected is detected by the first sensor 81 or the second sensor 82, the water faucet device 14 (water outlet 10a) is configured to continue rotating unless a rotation stop condition is met, such as the generation of a rotation stop command. In contrast, the water faucet device 14 (water outlet 10a) may be configured to rotate a fixed angle when an object to be detected is detected by the first sensor 81 or the second sensor 82, in other words, the water faucet device 14 and therefore the water outlet 10a may be configured to automatically stop after rotating a fixed angle.

The water outlet 10a may be configured to continue rotating while the first sensor 81 and the second sensor 82 continue to detect the object to be detected, and the rotation of the water outlet 10a may be stopped when the object to be detected is no longer detected. In this configuration, the object to be detected is moved in accordance with the rotation of the water outlet 10a, and the object to be detected is kept close to the first sensor 81 or the second sensor 82, so that the water outlet 10a rotates as if it is being pulled or pushed by the object to be detected.

In addition, in the first embodiment and the like, when the first sensor 81 or the second sensor 82 detects an object to be detected while the water faucet device 14 (water outlet 10a) is rotating, the rotation of the water faucet device 14 (water outlet 10a) is stopped. In other words, the operation related to stopping the rotation of the water outlet 10a is configured to be performed on both sensors 81 and 82. On the other hand, when the water outlet 10a is rotating in a predetermined direction, one of the two sensors 81 and 82 is the operation target related to stopping the rotation of the water outlet 10a, and when the water outlet 10a is rotating in the opposite direction to the predetermined direction, the other of the two sensors 81 and 82 is the operation target related to stopping the rotation of the water outlet 10a. For example, in the configuration of the first embodiment, when the water outlet 10a is rotating in a predetermined direction, the first sensor 81 may be the object of operation related to stopping the rotation of the water outlet 10a, and when the water outlet 10a is rotating in the opposite direction to the predetermined direction, the second sensor 82 may be the object of operation related to stopping the rotation of the water outlet 10a.

(e) In the second embodiment described above, the water faucet device 14 (water outlet 10a) is configured to rotate in the same direction as the movement direction of the detected object Do, but the water faucet device 14 (water outlet 10a) may be configured to rotate in the opposite direction to the movement direction of the detected object Do.

In addition, in a configuration in which sensors 81, 82 are arranged as in the second embodiment, the water faucet device 14 (water outlet 10a) may be configured to rotate when one of the sensors 81, 82 detects the object to be detected Do. In other words, the method for operating the water outlet 10 in the first embodiment may be applied to the configuration of the second embodiment.

(f) In the third embodiment described above, when the state is locked on, the state is maintained in the locked on state unless an operation for switching is performed. In contrast, the state may be configured to automatically switch from the locked on state to the non-locked on state after a predetermined time has elapsed since the state was switched to the locked on state.

(g) The switching between the locked-on state and the unlocked state in the third embodiment, and the switching between the rotation control mode and the water discharge/stop control mode in the fourth embodiment are configured to be performed by keeping the detected object close to the sensors 81, 82 for a predetermined time or more using the control device 76 (particularly the lock-on determination unit 764 and the mode switching unit 766). In contrast, for example, the switching may be performed by keeping the detected object close to the sensors 81, 82 for a time that is equal to or longer than a predetermined lower limit time (e.g., 3 seconds) and equal to or shorter than a predetermined upper limit time (e.g., 4 seconds). Also, the switching may be performed by bringing the detected object close to the sensors 81, 82 in a certain order (e.g., bringing the detected object close to the first sensor 81, the second sensor 82, and the first sensor 81 in this order).

In addition, switching between the locked-on state and the non-locked-on state, and between the rotation control mode and the water discharge/stop control mode may be performed using a manual switch. For example, the lock-on state or the rotation control mode may be achieved by turning the manual switch on, while the non-locked state or the water discharge/stop control mode may be achieved by turning the manual switch off.

(h) In the fourth embodiment, in the water discharge/stop control mode, the water discharge or stop at the water outlet 10a is switched by bringing a detected object close to the first sensor 81 or the second sensor 82. In contrast, in the water discharge/stop control mode, when a detection signal is output from each of the first sensor 81 and the second sensor 82, the operation of the solenoid valve 6 may be controlled so that water is discharged or stopped at the water outlet 10a according to the order in which these detection signals are output. In other words, the operating method for rotating the water outlet 10a in the second embodiment may be used as the operating method for switching between water discharge and water stop.

According to this configuration, in the water discharge/stop control mode, for example, when detection signals are output from the first sensor 81 and then the second sensor 82, one of water discharge and water stop is performed, and conversely, when detection signals are output from the second sensor 82 and then the first sensor 81, the other of water discharge and water stop is performed. Therefore, compared to when water discharge or water stop is performed simply by the detection of the object Do by one of the two sensors 81, 82, it is possible to make it less likely that water will be discharged or stopped unintentionally. This makes it possible to more effectively improve convenience for the user.

(i) Although not described in the above embodiment, in the third and fourth embodiments, a display means (e.g., a lamp capable of emitting light in two colors) may be provided to externally display whether the device is in a locked or unlocked state, or whether the device is in a rotation control mode or a water discharge/stop control mode.

(j) In the fifth embodiment, the foot switches 15, 16 are configured to perform operations related to rotating the water outlet 10a, but the foot switches 15, 16 may also be configured to be capable of performing operations related to switching between water discharge and water stop at the water outlet 10a. In this configuration, the object of operation by the foot switches 15, 16 may be configured to be switchable between the rotating device 7 (motor 72) or the solenoid valve 6, for example, by a manual switch or a sensor.

(k) In the fifth embodiment, the foot switches 15 and 16 are given as operating parts that can be operated using parts of the user other than the hands, but such operating parts are not limited to foot switches. Therefore, for example, as shown in FIG. 45, a first waist switch 18 and a second waist switch 19 that can be used to rotate the water outlet 10a using the user's waist or the surrounding area may be used. In this case, the same effects as those of the fifth embodiment are achieved. The configuration of the waist switches 18 and 19 is the same as that of the foot switches 15 and 16, and the first detection signal is output by pressing the first waist switch 18, and the second detection signal is output by pressing the second waist switch 19.

(l) Although not specifically mentioned in the above embodiment, from the viewpoint of preventing water from flowing out of the water storage section 100a, it is preferable to set the rotational range of the water faucet device 14 (water outlet 10a) so that the water outlet 10a is always positioned vertically above the water storage section 101a.

On the other hand, from the viewpoint of further improving convenience by increasing the rotational range of the faucet device 14 (water outlet 10a), the rotational range of the faucet device 14 (water outlet 10a) may be set so that the water outlet 10a can be positioned away from vertically above the water storage section 101a. When set in this manner, the water outlet 10a may be configured so that water cannot be discharged from the water outlet 10a or water discharge is stopped when the water outlet 10a is positioned away from vertically above the water storage section 101a.

(m) In the clutch section 78 of the above embodiment, the second intermediate transmission section 733 (second clutch gear 733a) is configured to be movable in a direction to release the meshing of both clutch gears 732a, 733a, but the first intermediate transmission section 732 (first clutch gear 732a) may be movable in a direction to release the meshing of both clutch gears 732a, 733a. Of course, both intermediate transmission sections 732, 733 (both clutch gears 732a, 733a) may be movable in a direction to release the meshing of both clutch gears 732a, 733a.

(n) In the above embodiment, the motor 72 is given as the energized operating unit, but an actuator other than a motor that operates when energized (such as a solenoid) may also be used as the energized operating unit.

(o) In the first embodiment and the like, the water outlet 10a is configured to switch between water outlet and water stop each time the water outlet/stop sensor 5 detects an object to be detected, and water outlet 10a is configured to continue to be discharged unless the water outlet/stop sensor 5 detects an object to be detected. In contrast, the water outlet 10a may be configured to continue to be discharged for a fixed period of time. This configuration may also be applied to the configuration of the fourth embodiment, i.e., the configuration in which sensors 81, 82 are used to switch between water outlet and water stop at the water outlet 10a.

(p) The shape of the water discharge section 10 in the above embodiment is an example and may be modified as appropriate. Therefore, although the outer second tubular section 32 and the inner second tubular section 42 in the above embodiment extend horizontally, for example, the outer second tubular section 32 etc. may be configured to extend obliquely upward from the outer first tubular section 31 side.

(q) In the above embodiment, a sink 101 is used as an example of a tank body, but the tank body to which the technical concept of the present invention can be applied is not limited to a sink. Therefore, the technical concept of the present invention may be applied to tank bodies other than sinks, such as bathtubs and washbasins.

(r) In the above embodiment, the top plate 101b of the sink 101 is given as the attachment target, but the attachment target is not limited to the top plate 101b of the sink 101 and may be changed as appropriate. For example, a counter in a kitchen may be used as the attachment target.

(s) The faucet system 1 may have an operating lever for switching water on or off at the water outlet 10a. In this case, the water outlet/stop sensor 5 does not need to be provided.

The faucet system 1 may also be capable of supplying hot water from the water outlet 10a.

(t) The position of the rotation device 7 is not limited to the above embodiment and may be changed as appropriate. For example, the entire rotation device 7 may be disposed in the front space 105.
