Description

  The present invention relates to an electronically controlled water faucet device, and more specifically, an electronically controlled water faucet device that converts movement of an operation lever of the water faucet device into an electrical signal and operates a flow rate adjustment valve and a temperature adjustment valve by electronic control. About.

  Faucet devices installed in kitchens, washrooms, bathrooms, toilets, etc. have functions for adjusting the flow rate of water (flow control) and temperature adjustment (temperature control) so that it can be used in various applications and usages. Yes. For example, a faucet device of a type called “single lever faucet” or the like is mechanically controlled by a displacement of one operating lever (single lever) moved by the user in the front / rear / left / right direction. ) And the temperature control valve (temperature control valve) to adjust the flow rate and temperature of the discharged water.

  However, in these faucet devices, since the size of the valve for performing flow control and temperature control is large, the design of the faucet body is restricted. In addition, since the operating feeling and operating force of the control lever are determined by the mechanical structure of the valve that performs flow control and temperature control, further improvement in terms of poor operating feeling and heavy operating force, etc. There is room.

  On the other hand, there is a hot water mixing apparatus that converts the movement of the operation lever of the single lever faucet into an electrical signal and operates the flow control valve and the temperature control valve by electronic control (for example, Patent Document 1). In the apparatus described in Patent Document 1, since the operation unit only needs to output an electrical signal, an operation force for mechanically moving the valve of the faucet is unnecessary, and an operation direction and an operation force are not required. The design of the faucet body becomes more free.

  However, since the device described in Patent Document 1 requires a follower piece and a rotary encoder to detect the tilt of the operation lever, there is a problem that the mechanism of this portion becomes large and waterproofing processing is not easy. .

On the other hand, there is an operation lever device in which an acceleration sensor is built in the operation lever (for example, Patent Documents 2 and 3). In the devices described in Patent Documents 2 and 3, the mechanism around the operation lever is simplified and miniaturized by incorporating the acceleration sensor in the operation lever.
JP-A-5-331888 JP 2000-342853 A Japanese Patent Laid-Open No. 11-154030

  However, the principle that the acceleration sensor detects the tilt of the operating lever is that the acceleration of gravity on the detection axis set in the acceleration sensor is first detected, and the tilt of the operating lever is calculated from the detected value. When used simply for a faucet device, there is a problem that the inclination of the faucet body when it is constructed, that is, the variation of the construction state with respect to the ground axis affects the control of the faucet.

  If the faucet body itself is tilted with respect to the ground axis, a steady error will result. In particular, in the case of wall-mounted faucets and the like, since the faucet body is fixed by using two water supply and fixing members called “attachment legs” on the hot water side and the water side, the two attachment legs Depending on the angle, the construction inclination of the faucet body appears remarkably. On the other hand, there is a case where it is desired to attach the operation lever freely in the vertical direction or the horizontal direction, or a case where it is desired to attach the operation lever diagonally due to a difference in the design of the faucet, instead of variations in the construction state. In that case, there is also a problem that the design value of inclination detection must be changed according to the situation.

  Or there is a problem that not only the variation of the construction state but also the manufacturing variation (mounting variation) of the acceleration sensor and the faucet device itself affects the control of the faucet. The acceleration sensor has an internal weight to detect gravitational acceleration, detects the displacement of the weight due to gravitational acceleration or acceleration of motion, for example, by detecting capacitance or detecting piezoresistance, and outputs the acceleration signal. Output. For this reason, the acceleration sensor needs to process a very weak signal, and the signal may change due to manufacturing variations or temperature changes, which may affect the control of the faucet.

  The present invention has been made on the basis of recognition of such a problem. Electronically controlled water that can reduce errors caused by variations in the construction state of the faucet body or manufacturing variations of the acceleration sensor or the faucet device itself. A plug device is provided.

  1st invention is the operation part for operating the water discharge flow volume and water discharge temperature of a faucet, the operation detection part which outputs the attitude | position of the said operation part as an electrical signal, The flow control valve which adjusts the said water discharge flow volume, A temperature control valve that adjusts the water discharge temperature; and a control unit that drives the flow control valve and the temperature control valve in accordance with an output of the operation detection unit, wherein the operation unit is an operation base end part The operation base end portion is fixed to the faucet body or a member to which the faucet body is fixed, and the operation distal end side is a free end to perform the tilting operation. When the operation detection unit has an acceleration sensor that detects the attitude of the operation unit, and the control unit moves the operation tip to the entire range where the tilt operation is possible The output range of the acceleration sensor is stored, and the acceleration is based on the output range. And calculating the attitude of the operation portion from the detection value capacitors is output, an electronic control faucet apparatus, characterized in that for driving at least one of the flow regulating valve and the temperature control valve.

  As a result, the control unit calculates the attitude of the operation unit based on the output range of the acceleration sensor when the operation tip is moved to the entire range in which the tilt operation is possible, and controls the temperature control valve and the flow control valve. In addition, it is possible to reduce errors caused by variations in construction state and manufacturing variations of the acceleration sensor and the electronic control faucet device itself.

  According to a second aspect, in the first aspect, the control unit drives the flow control valve and / or the temperature control valve according to the detection value output from the acceleration sensor. And a second mode for measuring and storing the output range of the acceleration sensor.

  As a result, the operations of the first mode and the second mode can be clearly separated, and are caused by variations in construction state and manufacturing variations of the acceleration sensor and the electronic control faucet device itself without deteriorating usability. The error can be reliably calibrated. Moreover, by having a 2nd mode, the response | compatibility in a construction site can also be performed flexibly. Furthermore, since it is possible to calibrate all errors at the final stage after construction, strict performance management from the manufacturing stage is unnecessary, and construction can also be performed using a level. Since it is not necessary to perform a treatment that prevents the faucet body from moving easily even after construction, the construction time and construction cost are reduced.

In a third aspect based on the second aspect, the control unit further includes a mode setting switch capable of manually switching between the first mode and the second mode. Features.
As a result, when the user presses the mode setting switch, the second mode is switched to the first mode, so that calibration can be performed reliably in an arbitrarily short time.

According to a fourth aspect, in the second or third aspect, the control unit drives the flow control valve so as to prohibit water discharge in the second mode.
As a result, since water discharge is prohibited in the second mode, calibration can be performed safely.

In addition, in a fifth invention according to any one of the second to fourth inventions, when the operation portion is stationary for a predetermined time in an inclined state corresponding to a water stop operation, the operation mode is automatically switched to the first mode. Features.
As a result, it is not necessary to switch from the second mode to the first mode after calibration is completed. That is, forgetting to return from the second mode to the first mode can be prevented. In addition, the automatic return to the first mode is limited to the case where the operation unit is stationary in the inclined state of the operation when the water faucet is stopped. Therefore, the automatic return to the first mode is possible. And no unexpected water discharge occurs.

  Further, a sixth invention is the invention according to any one of the second to fifth inventions, wherein the control unit is in a state where the detection value output by the acceleration sensor is larger than the output range in the first mode. When the detection value continues stably for a predetermined time, the detected value is larger than a value obtained by adding the output range and a predetermined first threshold value, and the output range and a predetermined second threshold value; The detected value is stored as a new output range when the value is smaller than the value obtained by adding.

  As a result, if the difference between the stored output range and the output range in use is slight, the acceleration sensor outputs the first mode in the normal use without requiring the shift to the second mode for calibration. Since the detected value is stored as a new output range, it is possible to automatically reduce an error caused by a change in the variation of the construction state and a change with time of the acceleration sensor.

Further, a seventh invention is the invention according to any one of the second to sixth inventions, wherein the control unit is in a state where the detection value output by the acceleration sensor is larger than the output range in the first mode. When the detection value continues stably for a predetermined time, when the detected value is larger than a value obtained by adding the output range and the predetermined second threshold value, the mode is switched to the second mode. .
As a result, if the difference between the memorized output range and the output range in use is large and it turns out that it is inappropriate to use the faucet as it is, the normal use of the faucet device is taken out of the first mode. Can be canceled and the process can proceed to the second mode for calibration to automatically perform calibration.

  ADVANTAGE OF THE INVENTION According to this invention, the electronically controlled water tap apparatus which can reduce the error which arises by the dispersion | variation in the construction state of a water faucet main body or the manufacture dispersion | variation which an acceleration sensor or a water faucet apparatus itself has is provided.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1 is a schematic view illustrating an electronically controlled faucet device according to an embodiment of the invention.
FIG. 2 is a schematic cross-sectional view illustrating a cross section of the electronically controlled faucet device according to this embodiment.

  The electronic control faucet device 10 according to the present embodiment includes an acceleration sensor 20, an operation unit 22 (hereinafter referred to as “operation lever”), a faucet body 24, and a lead wire 30. The operation lever 22 has an operation distal end portion 22a, an operation shaft 22b, and an operation base end portion 22c. Further, the acceleration sensor 20 is built in the operating tip 22 a of the operating lever 22. However, the acceleration sensor 20 may be built in the operation shaft 22 b of the operation lever 22. The operation lever 22 is an operation lever called a “single lever” or the like.

  The faucet body 24 includes a water discharge portion 26 and a support portion 28. The operation lever 22 is supported so as to be rotatable in the vertical direction and the horizontal direction, with the support portion 28 as a substantial center. A lead wire 30 and a water pipe 32 are built in the faucet body 24. One end of the lead wire 30 is connected to the acceleration sensor 20, and the other end is connected to a control unit 36 (see FIG. 3) described in detail later. Further, one end of the water distribution pipe 32 is connected to a solenoid valve 44 (see FIG. 3), which will be described in detail later, and the other end is connected to the water discharger 26.

FIG. 3 is a block diagram illustrating an electronically controlled water faucet device according to this embodiment.
The electronic control faucet device 10 of the present embodiment includes an operation detection unit 34, a control unit 36, motors 38 and 39, a temperature control valve 40 (hereinafter referred to as “mixing valve”), a flow control valve 42, And a solenoid valve 44. The operation detection unit 34 includes the acceleration sensor 20 and has a function of outputting an attitude of the operation lever 22 detected by the acceleration sensor 20 such as an inclined state or a rotation state as an electrical acceleration signal. The mixing valve 40 has a function of adjusting water discharge temperature by appropriately mixing hot water and water. The flow control valve 42 has a function of adjusting the water discharge flow rate.

  In the electronic control faucet device 10 of the present embodiment, the attitude of the operation lever 22 detected by the acceleration sensor 20 is converted into an electrical acceleration signal by the operation detection unit 34, and this acceleration signal is transmitted to the control unit 36 through the lead wire 30. Sent to. The control unit 36 sets the flow rate of water discharge and the control target value of the temperature according to the acceleration signal received from the operation detection unit 34. Further, the control unit 36 drives the mixing valve 40 through the motor 38 so as to substantially match the control target temperature, thereby mixing hot water and water.

  Simultaneously or before and after this, the electromagnetic valve 44 is driven while the flow control valve 42 is driven via the motor 39 so as to substantially match the control target flow rate. The solenoid valve 44 has a function of completely stopping hot water or water when it is not easy to stop the water only with the flow control valve 42. However, the electromagnetic valve 44 may not be provided.

  In the electronically controlled water faucet device 10 of the present embodiment, the water discharge flow rate and the water discharge temperature are controlled based on the attitude of the operation lever 22 detected by the acceleration sensor 20, so that the variation in the construction state of the water faucet body 24, that is, the earth axis Variations in the construction conditions with respect to can affect the control of the faucet. Furthermore, not only the variation in construction state but also the manufacturing variation (mounting variation) of the acceleration sensor 20 and the electronic control faucet device 10 itself affects the faucet control. Therefore, when the variation in construction state and the manufacturing variation of the acceleration sensor 20 or the electronic control faucet device 10 itself are large, the water discharge flow rate and the water discharge temperature may not be properly controlled. Therefore, it is necessary to perform correction according to the installation state of the electronic control faucet device 10.

  Therefore, the control unit 36 has storage means (not shown) for storing the output range of the acceleration sensor 20 when the operation lever 22 is moved in the full range of the vertical direction and the horizontal direction. The attitude of the operation lever 22 is calculated as a reference, and the mixing valve 40 and the flow control valve 42 are controlled. That is, after installing the electronic control faucet device 10, the user moves the operation lever 22 in the entire vertical and horizontal ranges, and the detected value of the acceleration sensor 20 at that time is a new storage range (output range). Remember as.

  As will be described in detail later, the control unit 36 controls a normal use mode (first mode) in which the mixing valve 40 and the flow control valve 42 are controlled (driven) in accordance with a detection value output from the acceleration sensor 20; A calibration mode (second mode) for measuring and storing the output range of the acceleration sensor 20. Switching between the normal use mode and the calibration mode can be performed manually by pressing a mode setting switch 46 of the control unit 36. On the other hand, when the operation lever 22 is stationary for a predetermined time at the water stop position, the calibration mode can be automatically switched to the normal use mode.

FIG. 5 is a schematic perspective view of the relationship between the angle and the control amount as viewed obliquely from above.
6 is a schematic diagram showing the relationship between the angle and the control amount, FIG. 6A is a schematic top view seen from above, and FIG. 6B is a schematic side view seen from the right side. FIG.

  As will be described later in detail, the operation lever 22 of the electronic control faucet device 10 according to the present embodiment has, for example, an elastic body 52 therein. In a state where the operation lever 22 stands in the vertical direction, the lower end of the elastic body 52 is fixed to a suitably set place on the faucet body 24, and the acceleration sensor 20 is provided on the upper end of the elastic body 52. Yes. Since the elastic body 52 is not fixed to the operation lever 22, it can move differently from the operation lever 22 inside the operation lever 22.

  At this time, the Z axis set in the acceleration sensor 20 is parallel to the longitudinal direction of the elastic body 52 and the operation lever 22, and the X axis and Y axis set in the acceleration sensor 20 are the elastic body 52 and the operation lever. The acceleration sensor 20 is preferably provided so as to be perpendicular to the longitudinal direction of 22. This is because by making the Z axis parallel to the longitudinal direction of the elastic body 52 and the operation lever 22, the reference of the direction becomes clear and the acceleration sensor 20 can be attached with high accuracy.

  Since the X axis and the Y axis of the acceleration sensor 20 are parallel to the operation direction of the operation lever 22, the acceleration sensor 20 can easily detect that the operation lever 22 has moved. On the other hand, since the Z axis of the acceleration sensor 20 is parallel to the rotation axis of the elastic body 52, it is not easily affected by the acceleration due to the movement of the operation. When the acceleration sensor 20 is located at the center of rotation of the elastic body 52, the Z axis is orthogonal to the direction of operation movement, and therefore no acceleration of movement occurs with respect to the Z axis. Therefore, the Z axis can always detect only the gravitational acceleration. However, when the acceleration sensor 20 is substantially at the tip of the operation shaft 22b, a centrifugal force is generated in the Z-axis by the movement of the operation, and thus detection in the Z-axis direction is not limited to only gravitational acceleration.

  Actually, the center of rotation of the operation lever 22 is a portion where the operation shaft 22b is attached to the faucet body 24, and is also a portion that influences the operation force, so that processing accuracy with the fixed portion is required. Therefore, it is not easy to attach the acceleration sensor 20 to a portion where the operation shaft 22b is attached to the faucet body 24. Further, from the viewpoint of the design of the electronically controlled water faucet device 10, it is preferable that the acceleration sensor 20 is built in a substantially central portion or a substantially tip portion of the operation shaft 22b.

  Further, in a state where the operation lever 22 stands in the vertical direction, the X axis set in the acceleration sensor 20 is parallel to the front-rear direction as viewed from the user, and the Y axis set in the acceleration sensor 20 is the user. It is preferable to provide the acceleration sensor 20 so as to be parallel to the left-right direction when viewed from the viewpoint.

  At this time, the operation lever 22 is operated in the vertical direction, and the water discharge flow rate is controlled with θ1 as an inclination angle (hereinafter referred to as “elevation angle”) with respect to the horizontal plane when the elastic body 52 and the operation lever 22 are inclined in the vertical direction. Can do. Further, by operating the operation lever 22 in the left-right direction, the water discharge temperature can be controlled with θ2 being the rotation angle in the horizontal plane with respect to the front when the elastic body 52 and the operation lever 22 are rotated in the left-right direction. That is, the control unit 36 drives the flow control valve 42 based on the elevation angle θ1 of the operation lever 22 to control the water discharge flow rate, and drives the mixing valve 40 based on the rotation angle θ2 of the operation lever 22 to discharge water temperature. Can be controlled.

なお、図６（ａ）に表したθ２のように、前方に対する右側方への水平面内の回動角度θ２を正とし、前方に対する左側方への水平面内の回動角度θ２を負と設定する。また、図６（ｂ）に表したθ１のように、水平面に対する上方への仰角θ１を正と設定する。 At this time, the relational expression between θ1 and θ2 and the detected values of the X axis, the Y axis, and the Z axis can be set as the following expression, for example.

As shown in θ2 shown in FIG. 6A, the rotation angle θ2 in the horizontal plane to the right side with respect to the front is set as positive, and the rotation angle θ2 in the horizontal plane to the left side with respect to the front is set as negative. . Further, as shown by θ1 shown in FIG. 6B, the upward elevation angle θ1 with respect to the horizontal plane is set to be positive.

  Expression (3) is a relational expression when a triaxial acceleration sensor is used as the acceleration sensor 20. Thus, if a triaxial acceleration sensor is used as the acceleration sensor 20, the water discharge flow rate can be controlled by the detected value of the Z axis, and the water discharge temperature is controlled by the detected values of the X axis and the Y axis. Therefore, calculation and control are simplified. Note that a biaxial acceleration sensor may be used as the acceleration sensor 20. In this case, the elevation angle θ1 and the rotation angle θ2 are obtained by the equations (1) and (2).

FIG. 7 is a schematic view illustrating the internal structure of the operation lever.
As described above, the operation lever 22 has, for example, the elastic body 52 inside. The elastic body 52 is made of, for example, a rubber material. The acceleration sensor 20 is provided at the upper end 52a of the elastic body 52. The installation direction of the acceleration sensor 20 is as described above, for example. Further, the end face 52b is fixed at a suitably set place in the faucet body 24. The operation lever 22 and the elastic body 52 are not fixed and have a double structure. Therefore, the elastic body 52 can move differently from the operation lever 22 inside the operation lever 22.

  Since the elastic body 52 is fixed at the lower end 52b, for example, when the operation lever 22 is rotated in the direction of the arrow 200, that is, in the direction in which the rotation angle θ2 is positive (see FIG. 6 (a)). When 22 is rotated, the elastic body 52 is twisted in the direction of the arrow 202. With this operation, the acceleration sensor 20 also rotates in the direction of the arrow 202.

  Therefore, when the elastic body 52 is facing forward in a substantially horizontal plane (both θ1 and θ2 are 0 degrees) as in the operation of the operation lever 22 shown in FIG. 4, the detected values of the X axis and the Y axis are Whereas each is about 1 g (g = gravitational acceleration, the same applies hereinafter) and about 0 g, when the rotation angle θ2 is about 45 degrees, the detected values of the X-axis and the Y-axis are about 0.7 g, 0, respectively. About 7g. When the acceleration sensor 20 is stationary, the square root of the sum of the squares of the detected values of the X axis, the Y axis, and the Z axis is “1”. When θ2 is about 45 degrees, the detected values of the X axis and the Y axis are about 0.7 g and 0.7 g, respectively.

  Further, when the rotation angle θ2 of the elastic body 52 is about 45 degrees, the twist angle of the elastic body 52 with respect to the arrow 202 is appropriately set so as to be about 45 degrees. Thus, when the operating lever 22 is rotated in the left-right direction, the acceleration sensor 20 is also rotated at the same time, and the detected values of the X axis and the Y axis change.

FIG. 8 is a flowchart illustrating the main routine of the operation of the electronically controlled water faucet device according to this embodiment.
First, it is determined whether or not the mode setting switch 46 is pressed (step S104). When the mode setting switch 46 is pressed (step S104: ON), the normal use mode (first mode) is switched to the calibration mode (second mode). In the calibration mode, an acceleration sensor output range storage subroutine, which will be described in detail later, is performed (step S200).

  When the mode setting switch 46 is not pressed (step S104: OFF), A / D conversion (analog / digital conversion) of the detection value output from the acceleration sensor 20 is performed (step S106). Subsequently, when the A / D converted value is stable for a predetermined time in a state where the value is larger than the storage range stored in the control unit 36, the A / D converted value is transferred to the control unit 36. It is determined whether or not the stored storage range is larger than a value obtained by adding the appropriately set “threshold value 2 (second threshold value)” (step S108). When the A / D converted value is larger than the value obtained by adding the storage range stored in the control unit 36 and the appropriately set “threshold value 2” (step S108: Y), the normal use mode Is switched to the calibration mode, and the acceleration sensor output range storage subroutine is operated (step S200). In other words, when the A / D converted value greatly deviates from the stored range, the mode is switched to the calibration mode.

  When the A / D converted value is smaller than the value obtained by adding the storage range stored in the control unit 36 and the appropriately set “threshold value 2” (step S108: N), the A / D It is determined whether or not the converted value is larger than a value obtained by adding the storage range stored in the control unit 36 and an appropriately set “threshold value 1 (first threshold value)” (step S110). . When the A / D converted value is larger than the value obtained by adding the storage range stored in the control unit 36 and the appropriately set “threshold value 1” (step S110: Y), it will be described in detail later. The acceleration sensor output range correction subroutine is performed (step S300). That is, when the A / D converted value slightly deviates from the stored range, the A / D converted value at that time is set as a new storage range (output range) without switching to the calibration mode. Remember.

  Subsequently, an operation of an acceleration correction subroutine, which will be described in detail later, is performed (step S400). Subsequently, an operation of an acceleration / control target data conversion subroutine, which will be described in detail later, is performed (step S500). Subsequently, it is determined whether or not the set flow rate of the flow control valve 42 is equal to the target water discharge flow rate (step S112). When the set flow rate of the flow control valve 42 is not equal to the target water discharge flow rate (step S112: N), the control unit 36 drives the flow control valve 42 to control it to be equal to the target water discharge flow rate (step S112: N). Step S114).

  Subsequently, it is determined whether or not the set temperature of the mixing valve 40 is equal to the target water discharge temperature (step S116). If the set temperature of the mixing valve 40 is not equal to the target water discharge temperature (step S116: N), the control unit 36 drives the mixing valve 40 to control it to be equal to the target water discharge temperature (step S118). ).

  Subsequently, it is determined whether or not the target water discharge flow rate is “0” (step S120). When the target water discharge flow rate is “0” (step S120: Y), it is determined whether or not the electromagnetic valve 44 is closed (step S122). If the electromagnetic valve 44 is not closed (step S122: N), the control unit 36 drives the electromagnetic valve 44 to close (step S124). On the other hand, when the target water discharge flow rate is not “0” (step S120: N), it is determined whether or not the electromagnetic valve 44 is open (step S126). When the electromagnetic valve 44 is not opened (step S126: N), the control unit 36 drives the electromagnetic valve 44 to open (step S128).

  As described above with reference to FIG. 8, in the electronic control faucet device 10 according to the present embodiment, the A / D converted value is appropriately set with the storage range stored in the control unit 36. When the value is larger than the value obtained by adding “Threshold 1”, the A / D converted value at that time is stored as a new storage range. Errors caused by changes and the like can be automatically reduced. In addition, when the A / D converted value is larger than the value obtained by adding the storage range stored in the control unit 36 and the appropriately set “threshold value 2”, the mode is switched to the calibration mode. When calibration becomes necessary, calibration can be automatically performed.

Hereinafter, each subroutine will be described with reference to the drawings.
FIG. 9 is a flowchart illustrating an acceleration sensor output range storage subroutine of the electronically controlled faucet device according to this embodiment.
The flowchart shown in FIG. 9 is a subroutine for storing the output range of the acceleration sensor 20. As described above, when the electronic control faucet device 10 according to the present embodiment has a large variation in the construction state of the faucet body 24 and the manufacturing variation of the acceleration sensor 20 or the electronic control faucet device 10 itself, There is a possibility that the water discharge flow rate and the water discharge temperature may not be properly controlled. Therefore, after installing the electronic control faucet device 10, the user moves the operation lever 22 in the entire range in the vertical direction and the horizontal direction, and the detected value of the acceleration sensor 20 at that time is a new storage range (output range). As a calibration mode.

  First, “−1” is set as the maximum value of the storage range stored in the control unit 36 and “+1” is set as the minimum value (step S202). That is, the storage range stored in the control unit 36 is once deleted, and the range is gradually expanded.

  Subsequently, A / D conversion of the detection value output from the acceleration sensor 20 is performed (step S204). Subsequently, it is determined whether or not the combined value of the detected values of the X axis, the Y axis, and the Z axis of the acceleration sensor 20 is about “1” (step S206). If the composite value is not about “1” (step S206: N), A / D conversion of the detection value output from the acceleration sensor 20 is performed again (step S204). That is, when the acceleration sensor 20 is not stationary, the acceleration sensor 20 outputs not only the gravity acceleration component corresponding to the tilt state of the operation lever 22 but also the acceleration with respect to the movement of the operation lever 22. Therefore, the storage range is not changed.

  When the combined value of the detected values of the X-axis, Y-axis, and Z-axis of the acceleration sensor 20 is about “1” (step S206: Y), the A / D converted value is used as the control unit 36. It is determined whether it is larger than the maximum value of the storage range stored in (step S208). When the A / D converted value is larger than the maximum value of the storage range stored in the control unit 36 (step S208: Y), the A / D converted value is used as the maximum value of the new storage range. (Step S210).

  Subsequently, it is determined whether or not the A / D converted value is smaller than the minimum value of the storage range stored in the control unit 36 (step S212). When the A / D converted value is smaller than the minimum value of the storage range stored in the control unit 36 (step S212: Y), the A / D converted value is used as the new minimum value of the storage range. (Step S214).

Subsequently, it is determined whether or not the storage range stored in the control unit 36 is equal to or greater than the half value of the design range (step S216). When the storage range stored in the control unit 36 is not equal to or greater than the half value of the design range (step S216: N), A / D conversion of the detection value output from the acceleration sensor 20 is performed again (step S204). . That is, if the storage range does not become at least 50% or more of the design range, it is determined that the output range is not sufficiently measured because the discrepancy between the storage range and the design range at this time is too large, and the storage range is stored. Does not end the operation.
Note that step S216 is a safety measure process for more reliably completing the calibration mode, and the ratio of the half value (50%) is not limited to this, and can be changed as appropriate. Alternatively, in the case of an application (FIGS. 24 and 25) that changes the installation direction of the operation lever described later, the determination in step S216 may be omitted.

  Subsequently, it is determined whether or not the mode setting switch 46 is pressed (step S218). When the mode setting switch 46 is pressed (step S218: ON), the acceleration sensor output range storage subroutine is terminated, and the process returns to the main routine shown in FIG. 8 (step S222). On the other hand, when the mode setting switch 46 is not pressed (step S218: OFF), an acceleration correction subroutine, which will be described in detail later, is performed (step S400). Subsequently, an operation of an acceleration / control target data conversion subroutine, which will be described in detail later, is performed (step S500).

  Subsequently, it is determined whether or not 60 seconds elapse while the target water discharge flow rate remains in a state of about “0” (step S220). If the target water discharge flow rate remains approximately “0” and 60 seconds have elapsed (step S220: Y), the acceleration sensor output range storage subroutine is terminated and the main routine shown in FIG. 8 is executed. Return (step S222). That is, when the operation lever 22 is stationary for a predetermined time at the water stop position, it automatically switches to the normal use mode, thereby preventing forgetting to return to the normal use mode. Moreover, since the automatic return to the normal use mode is performed only when the operation lever 22 is at the water stop position, water is not unexpectedly discharged even if left in the calibration mode. The elapsed time is not limited to 60 seconds and can be changed as appropriate.

  As described above with reference to FIG. 9, the electronic control faucet device 10 according to the present embodiment has the acceleration sensor output range storage subroutine as the calibration mode, and thus operates in the normal use mode and the calibration mode. It can be clearly divided and can be calibrated reliably without deteriorating usability. Furthermore, by having a calibration mode, it is possible to flexibly cope with the construction site.

  On the other hand, when there is no calibration mode, the faucet is controlled by accumulating various errors and variations, such as manufacturing variations of acceleration sensors, assembly errors of faucets, and construction errors. Therefore, in order to ensure proper operation of the faucet, strict performance management is required for each stage from the manufacturing stage. In addition, it is necessary to perform construction using a level, or to perform processing that does not easily move even after construction. Therefore, since it leads to increase in construction time and construction cost, it is not preferable.

  Further, the electronic control faucet device 10 according to the present embodiment simply calibrates when the user presses the mode setting switch 46 to end the acceleration sensor output range storage subroutine and return to the main routine. be able to. On the other hand, when the operation lever 22 is stationary for a predetermined time at the water stop position, the mode is automatically switched to the normal use mode, so that it is possible to prevent forgetting to return to the normal use mode.

FIG. 10 is a flowchart illustrating an acceleration sensor output range correction subroutine of the electronically controlled faucet device according to this embodiment.
FIG. 11 is a schematic diagram for explaining the operation of correcting the output range of the acceleration sensor from the error between the storage range and the design range.

  The flowchart shown in FIG. 10 is a subroutine for finely correcting the output range. First, it is determined whether or not the combined value of the detected values of the X-axis, Y-axis, and Z-axis of the acceleration sensor 20 is about “1” (step S302). If the composite value is not about “1” (step S302: N), the acceleration sensor output range correction subroutine is terminated and the process returns to the main routine shown in FIG. 8 (step S312). That is, when the acceleration sensor 20 is not stationary, the storage range is not corrected.

  On the other hand, when the combined value of the detected values of the X-axis, Y-axis, and Z-axis of the acceleration sensor 20 is about “1” (step S302: Y), the A / D converted value is controlled. It is determined whether or not it is larger than the maximum value of the storage range stored in the unit 36 (step S304). When the A / D converted value is larger than the maximum value of the storage range stored in the control unit 36 (step S304: Y), the A / D converted value is used as the maximum value of the new storage range. (Step S306).

  Subsequently, it is determined whether or not the A / D converted value is smaller than the minimum value of the storage range stored in the control unit 36 (step S308). When the A / D converted value is smaller than the minimum value of the storage range stored in the control unit 36 (step S308: Y), the A / D converted value is used as the new minimum value of the storage range. (Step S310). Subsequently, the acceleration sensor output range correction subroutine is terminated, and the process returns to the main routine shown in FIG. 8 (step S312). With the above operation, if the output of the acceleration sensor 20 is a slight change, the memory range can be used while using the faucet device without the user being aware of anything even if the normal mode is not shifted to the calibration mode. Can be corrected appropriately.

FIG. 12 is a flowchart illustrating an acceleration correction subroutine of the electronically controlled faucet device according to this embodiment.
The flowchart shown in FIG. 12 is a subroutine for correcting the detected value (acceleration) detected by the acceleration sensor. This correction calculation is executed as a linear function. That is, if the linear function for correction is f (x) = ax + b, “slope a” and “intercept b” are obtained. First, the center value of the maximum value and the minimum value of the storage range is obtained (step S402). Similarly, the center value of the maximum value and the minimum value of the design range (the output range of the acceleration sensor at the design standard value when manufacturing and construction variations are all zero) is obtained (step S402). Further, an offset correction value that is a difference between the center value of the storage range and the center value of the design range is obtained (step S402). That is, the deviation amount between the center of the design value output by the acceleration sensor (value that bisects the design range) and the center of the actual output range (value that bisects the storage range) is obtained. This corresponds to “intercept b” of the linear function.

  Subsequently, an inclination correction value that is a ratio between the difference between the maximum value and the minimum value of the storage range and the difference between the maximum value and the minimum value of the design range is obtained (step S404). That is, the ratio between the width of the design value and the width of the actual output value is obtained. This corresponds to the “gradient a” of the linear function. Subsequently, a difference between the A / D converted acceleration value and the offset correction value obtained in step S402 is obtained as an acceleration after offset correction (step S406). This means that the center of the design range is matched with the center of the actual output range.

  Subsequently, a value obtained by dividing the difference between the acceleration after offset correction obtained in step S406 and the center value of the design range by the inclination correction value obtained in step S404, and adding the center value of the design range to the quotient. Is obtained as the corrected acceleration (step S408). That is, the correction of the ratio between the difference between the maximum value and the minimum value of the storage range and the difference between the maximum value and the minimum value of the design range is added with the center value of the design range as a reference. Subsequently, the acceleration correction subroutine is terminated, and the process returns to the main routine shown in FIG. 8 (step S410). Note that the calculation of the flowchart shown in FIG. 12 needs to be performed for each of the X axis, the Y axis, and the Z axis. However, when the acceleration sensor 20 is a biaxial acceleration sensor, the calculation about the Z axis is not necessary.

FIG. 13 is a flowchart illustrating an acceleration / control target data conversion subroutine of the electronically controlled faucet device according to this embodiment.
The flowchart shown in FIG. 13 is a subroutine for setting the target value of the water discharge flow rate and the water discharge temperature from the corrected acceleration. First, the target value of the water discharge flow rate is set from the acceleration detected by the acceleration sensor 20 according to the water discharge flow rate table (see FIG. 21) described in detail later (step S502). Subsequently, the target value of the water discharge temperature is set from the acceleration detected by the acceleration sensor 20 according to the water discharge temperature table (see FIG. 22) described in detail later (step S504). Subsequently, the acceleration / control target data conversion subroutine is terminated, and the process returns to the main routine shown in FIG. 8 (step S506).

Hereinafter, a method for obtaining the water discharge flow rate table (see FIG. 21) and the water discharge temperature table (see FIG. 22) will be described with reference to the drawings.
The electronically controlled water faucet device according to the present embodiment can determine the control amounts θ1 and θ2 by referring to a table, for example, assuming control by a microcomputer and avoiding complicated calculation of trigonometric functions. That is, the control target value of the water discharge flow rate and the water discharge temperature can be determined with reference to the table obtained from the combination of the detected values of the X axis and the Y axis. Note that such a table can be stored as data in a memory provided in the control unit 36, for example.

  As a precondition for obtaining the table, the elevation angle θ1 of the operation lever 22 is set to 0 to 60 degrees. That is, it is assumed that the structure of the support portion 28 to which the operation lever 22 is attached is designed so that θ1 can be operated in the range of 0 to 60 degrees. Here, when θ1 is 0 degrees, the discharged water flow rate is minimized (control target value = 0), and when θ1 is 60 degrees, the discharged water flow rate is maximized (control target value = 100). That is, when θ1 is 0 degree, the water stop state is set, and the water discharge flow rate is increased as θ1 increases. Further, the rotation angle θ2 of the operation lever 22 is set to 0 ± 60 degrees. In other words, it is assumed that the structure of the support portion 28 to which the operation lever 22 is attached is designed so that θ2 can be operated in the range of 0 ± 60 degrees. Here, when θ2 is +60 degrees, the water discharge temperature is 15 degrees (minimum temperature), and when θ2 is −60 degrees, the water discharge temperature is 45 degrees (maximum temperature). That is, the water discharge temperature is set to 30 ± 15 degrees. These numerical values are all design standard values that do not include errors such as manufacturing variations.

  As described with reference to FIGS. 4 to 6, the elevation angle θ <b> 1 is 0 degrees indicates that the operation lever 22 is at the lowest end of the movable range, and the rotation angle θ <b> 2 is 0 degrees. This represents a state in which the operation lever 22 faces forward, that is, toward the user in a substantially horizontal plane. Further, the rotation angle θ2 to the right with respect to the front is set to be positive, and the rotation angle θ2 to the left with respect to the front is set to be negative. Further, the upward elevation angle θ1 with respect to the horizontal plane is set to be positive.

  The reason why the water discharge temperature is set to the lowest temperature when θ2 is +60 degrees and the water discharge temperature is set to the highest temperature when θ2 is −60 degrees is that the conventional method of using a single lever faucet is followed. For each detected value of the X-axis and the Y-axis, calculation is performed for a range of ± 1 g that may occur due to gravitational acceleration. The minimum unit of gravitational acceleration is 0.1 g. However, the present invention is not limited to this, and may be changed as appropriate. In this calculation method, the detected values of the X axis and the Y axis are used without using the detected value of the Z axis.

First, √ (X ² + Y ² ) is calculated from the detected value (X) on the X axis and the detected value (Y) on the Y axis. The calculation result table is as shown in FIG. Subsequently, when the acceleration sensor 20 is stationary, the square root of the sum of the squares of the detected values of the X-axis and the Y-axis does not exceed 1 g of the gravitational acceleration, so the table shown in FIG. From this, the range exceeding “1” is excluded. The calculation result table is as shown in FIG.

Since the elevation angle θ1 of the operating lever is 0 to 60 degrees, the range of cos θ1 is 0.5 to 1. That is, from the formula (1), the range of √ (X ² + Y ² ) is 0.5 to 1. Therefore, the range where √ (X ² + Y ² ) is less than 0.5 is excluded from the table shown in FIG. The calculation result table is as shown in FIG. Subsequently, θ1 is obtained from Expression (1) for each value in the table shown in FIG. The calculation result table is as shown in FIG.

  Subsequently, in the range of the table shown in FIG. 16, the detected value (X) of the X axis and the detected value (Y) of the Y axis are substituted into Expression (2) to obtain θ2. The calculation result table is as shown in FIG. Subsequently, since the rotation angle θ2 of the operation lever 22 is 0 ± 60 degrees, the range where θ2 exceeds 0 ± 60 degrees is excluded from the table shown in FIG. The calculation result table is as shown in FIG. Similarly, a range where θ2 exceeds 0 ± 60 degrees is excluded from the table shown in FIG. The calculation result table is as shown in FIG.

  Subsequently, for each value in the table shown in FIG. 19, the water discharge flow rate when θ1 is 0 degrees is assigned as the minimum (control target value = 0), and the water discharge flow rate when θ1 is 60 degrees is maximized. (Control target value = 100) is assigned. The calculation result table is as shown in FIG. Similarly, for each value in the table shown in FIG. 20, the water discharge temperature when θ2 is +60 degrees is assigned to 15 degrees (minimum temperature), and the water discharge temperature when θ2 is −60 degrees. Is assigned 45 degrees (maximum temperature). The calculation result table is as shown in FIG.

  In this way, the water discharge flow rate and the water discharge temperature are assigned to the control amounts θ1 and θ2, respectively. Therefore, the control microcomputer only needs to have the tables shown in FIGS. 21 and 22, and in order to set the control target value from the detected values of the X axis and the Y axis, the steps in the flowchart shown in FIG. In S502 and step S504, the tables in FIGS. 21 and 22 may be referred to, respectively.

FIG. 23 is a time chart illustrating the relationship between the detected value of the acceleration sensor in the calibration mode, and the flow control valve and the mixing valve.
In the electronic control faucet device 10 of the present embodiment, as described above, when the variation in the construction state of the faucet body 24 and the manufacturing variation of the acceleration sensor 20 or the electronic control faucet device 10 itself are large, There is a possibility that the water discharge flow rate and the water discharge temperature may not be properly controlled. Therefore, after installing the electronically controlled water faucet device 10, the user moves the operating lever 22 in the entire vertical and horizontal ranges, and stores the detection value of the acceleration sensor 20 at that time as a new storage range. Has a mode.

  In this calibration mode, the user moves the operating lever 22 in all the ranges that can be operated in the vertical and horizontal directions, and the X-axis maximum detected value (X limit) of the acceleration sensor 20 at that time is stored in the storage range. Store as the maximum value of X, and store the minimum detection value (-limit of X) as the minimum value of X in the storage range. Similarly, the maximum detected value (Y limit) of the Y axis of the acceleration sensor 20 is stored as the maximum value of Y in the storage range, and the minimum detection value (−limit of Y) is stored as the minimum value of Y in the storage range. Store as a value.

  At this time, the control unit 36 fully closes the flow control valve 42 so that the water discharge flow rate becomes “0” regardless of the state of the operation lever 22, that is, regardless of the output of the acceleration sensor 20. Further, the control unit 36 sets the mixing valve 40 to “medium” so that the water discharge temperature becomes “medium”. Thus, by prohibiting water discharge in the calibration mode, the operation lever can be moved freely without flowing wasteful water or hot water, and the electronic control faucet device 10 can be calibrated safely. it can.

Next, a modification of the present embodiment will be described with reference to the drawings.
FIG. 24 is a schematic view illustrating an electronically controlled faucet device according to a modification of the present embodiment, and FIG. 24 (a) is a schematic view when the operation lever is installed on the upper surface of the washstand. FIG. 24B is a schematic diagram when the operation lever is installed on the wall surface.
Similar to the electronically controlled faucet device shown in FIG. 1, the electronically controlled faucet device 10 shown in FIGS. 24A and 24B includes an acceleration sensor 20, an operation lever 22, a faucet body 24, It has. The acceleration sensor 20 is built in the operation tip 22 a of the operation lever 22. However, the acceleration sensor 20 may be built in the operation shaft 22 b of the operation lever 22. The operation lever 22 is an operation lever called a “single lever” or the like.

  The operation lever 22 of the electronically controlled water faucet device 10 shown in FIG. 24A is provided on the upper surface of the wash basin 70, and is supported so as to be rotatable in the vertical and horizontal directions around the support portion 28. Has been. On the other hand, the operation lever 22 of the electronically controlled water faucet device 10 shown in FIG. 24B is provided on the wall surface 74 extending to the rear part of the wash basin 70, and the vertical direction with the support portion 28 as the center. And it is supported so as to be rotatable in the left-right direction.

  As described above, even when the mounting direction of the operation lever 22 is different, the electronic control faucet device 10 according to the present modification is performed by performing the operations of the flowcharts shown in FIGS. 8 to 10 and FIGS. The water discharge flow rate and the water discharge temperature can be controlled appropriately. Therefore, the installation direction and angle of the operation lever 22 can be freely changed at the construction site.

FIG. 25 is a schematic view illustrating an electronically controlled faucet device according to another modified example of this embodiment.
The electronic control faucet device 10 shown in FIG. 25 includes an acceleration sensor 20, an operation lever 22, and a faucet body 24, similarly to the electronic control faucet device shown in FIG. Since the installation method of the acceleration sensor 20 is the same as that of the electronically controlled water faucet device shown in FIG. 1, detailed description thereof is omitted.

  The operation lever 22 is provided at the lower part of the faucet body 24 so that the water stop position is in an oblique posture, and is supported so as to be rotatable in the vertical direction and the horizontal direction about the support portion 28. ing. Thus, even when the operation lever 22 is attached so that the water stop position is in an oblique posture, the operation of the flowchart shown in FIGS. 8 to 10 and FIGS. The electronically controlled water faucet device 10 according to the modification can appropriately control the water discharge flow rate and the water discharge temperature.

  Therefore, even when the operation lever 22 is shared by a plurality of electronically controlled water faucet devices having different designs, it is not necessary to individually set the control parameters for the water discharge flow rate and the water discharge temperature for the detection value of the acceleration sensor 20. Also, depending on the installation state of the electronic control faucet device 10 at the construction site, the operation lever 22 is desired to be used in an area closer to the front of the user, or the operation lever 22 is desired to be used with a small operation amount depending on the user's physical condition. It is possible to respond to requests such as. That is, a member (for example, a so-called “stopper”) that interferes when the operation lever 22 tilts is added to the support portion 28 according to the situation at the site, and the operation range of the operation lever 22 is mechanically desired. And the operations shown in the flowcharts shown in FIGS. 8 to 10 and FIGS. 12 to 13 may be performed within the suppressed range.

  As described above, according to the present embodiment, the control unit 36 has storage means for storing the output range of the acceleration sensor 20 when the operation lever 22 is moved in the entire vertical and horizontal ranges. Since the position of the operation lever 22 is calculated based on this output range and the mixing valve 40 and the flow control valve 42 are controlled, the construction state variation and the acceleration sensor 20 and the electronic control faucet device 10 itself have. Errors caused by manufacturing variations can be reduced.
