JP, 2008-168230, A

However, the distance from the water discharge portion to the wall of the bathroom along the direction in which the wash water is discharged varies depending on the angle at which the water discharge portion rotates. If water is spouted in the same manner in all directions in such a state, there may be a region on the wash floor where sprinkling water is excessively discharged. Therefore, a large amount of cleaning water may be required.

The present invention has been made based on the recognition of such a problem, and an object of the present invention is to provide a water spouting device for a bathroom washing place that can wash the entire washing place floor with a small amount of washing water.

A first aspect of the present invention is a water spouting device for a bathroom washing place, which spouts washing water on a washing floor surrounded by walls that are provided upright, wherein the washing water is spouted on the washing floor and the washing water is spouted. A water spouting part whose position changes so as to change the area, and a controller which controls the fluctuation of the position of the water spouting part, wherein the controller spouts the water along the direction in which the wash water is spouted. The total amount of the wash water discharged from the water discharger in the position variation range of the water discharger when the distance between the wall and the wall surface is relatively short, along the direction in which the wash water is discharged. When the distance between the water discharger and the wall surface is relatively long, a control is performed to reduce the total amount in the position variation range of the water discharger, and the instantaneous flow rate of the wash water discharged from the water discharger is It is constant, and the control unit changes the average rotation speed of the water discharge unit according to the distance from the water discharge unit to the wall surface along the direction in which the wash water is discharged. Water spouting device.

According to this water discharge device for a bathroom washing place, not only the washing water that directly reaches the washing place floor from the water discharge portion, but also the washing water that flows on the washing place floor after hitting the wall surface can be used for washing. When the distance from the spouting part to the wall surface along the direction in which the cleaning water is discharged is short, the amount of cleaning water that flows on the floor of the washing place after hitting the wall surface is relatively large, so the cleaning effect can be obtained even if the amount of cleaning water is reduced. You can Therefore, when the distance from the water discharge portion along the direction in which the wash water is discharged to the wall surface is short, it is possible to prevent the amount of wash water from being discharged more than necessary and to reduce the total amount of wash water discharged to the entire wash floor. Can be reduced. Further, according to this water discharge device for bathroom washing place, the amount of wash water discharged can be controlled by a simple control of controlling the average rotation speed. When the wash water is sterilized water, the concentration of the sterilized water can be made constant by making the instantaneous flow rate of the wash water discharged from the water discharge part constant. Furthermore, by changing the average rotation speed of the water discharge part, it is possible to change the total amount of wash water discharged into a predetermined range on the floor of the wash floor while keeping the concentration of the sterilized water constant.

According to this water spouting device for a bathroom washing place, the amount of washing water discharged to the upstream side of the washing place floor is made smaller than the amount of washing water discharged to the downstream side of the washing place floor, so that the entire washing place floor is The total amount of washing water required for washing can be reduced. The wash water discharged on the upstream side of the washing floor flows to the downstream side of the washing floor. Therefore, it is possible to wash the downstream side of the wash floor by using the wash water discharged to the upstream side of the wash floor. Thereby, even if the amount of wash water discharged to the downstream side of the wash floor is reduced, the entire wash floor can be washed.

When the distance between the water discharger and the wall surface is relatively long, a control is performed to reduce the amount of water below the total amount in the position variation range of the water discharger, and the controller controls the wash water to be upstream of the washing floor. The distance between the water discharge portion and the wall surface along the direction in which the water is discharged to the side is between the water discharge portion and the wall surface in the direction in which the wash water is discharged to the downstream side of the wash floor. When the distance is the same, the amount of the wash water discharged to the downstream side is smaller than the amount of the wash water discharged to the upstream side. ..

According to this water discharge device for a bathroom washing place , not only the washing water that directly reaches the washing place floor from the water discharge portion, but also the washing water that flows on the washing place floor after hitting the wall surface can be used for washing. When the distance from the spouting part to the wall surface along the direction in which the cleaning water is discharged is short, the amount of cleaning water that flows on the floor of the washing place after hitting the wall surface is relatively large, so the cleaning effect can be obtained even if the amount of cleaning water is reduced. You can Therefore, when the distance from the water discharge portion along the direction in which the wash water is discharged to the wall surface is short, it is possible to prevent the amount of wash water from being discharged more than necessary and to reduce the total amount of wash water discharged to the entire wash floor. Can be reduced.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same components are designated by the same reference numerals, and detailed description thereof will be appropriately omitted.

FIG. 1 is a schematic diagram illustrating a bathroom spout water discharge device according to an embodiment of the present invention.
As shown in FIG. 1, a bathroom flush water spouting device (hereinafter, simply referred to as “water spouting device”) 100 according to an embodiment of the present invention includes a water spouting unit 10 a and a control unit 30. Prepare The water discharge device 100 is a device that is installed in a bathroom and cleans a washing floor of the bathroom.

First, an example of a bathroom in which the water discharger 100 is installed will be described.
FIG. 2( a) and FIG. 2( b) are schematic perspective views showing a bathroom in which the bathroom flushing water discharge device according to the present embodiment is installed.
As shown in FIG. 2A, bathroom 500 in which water discharge device 100 is installed is provided with first to fourth walls 541 to 544, bathtub 510, wash floor 520 and counter 530. Further, the bathroom 500 is appropriately provided with a mirror, a water tap, a shower hose, and the like. FIG. 2B is an enlarged schematic perspective view of the vicinity of the counter 530.

Bathroom 500 has first to fourth walls 541 to 544. The second wall 542 is a wall facing the first wall 541. The fourth wall 544 is a wall that faces the third wall 543. The first wall 541 and the second wall 542 are connected to the third wall 543 and the fourth wall 544, respectively.

The bathtub 510 is provided on the fourth wall 544 side when viewed from the wash floor 520. For example, the bathtub 510 is arranged so as to contact the fourth wall 544.

The washing floor 520 is provided between the bathtub 510 and the third wall 543. For example, the wash floor 520 contacts the first to third walls 541 to 543.

The washing floor 520 is surrounded by a wall surface 540 that stands upright. Here, the “wall surface” includes not only the first to fourth walls 541 to 544 but also the side surface of the bath 510. In this example, the wall surface 540 surrounding the wash floor 520 is the side surfaces of the first to third walls 541 to 543 and the bath 510. Note that the first to fourth walls 541 to 544 may include bathroom doors and the like.

In this specification, the direction from the second wall 542 to the first wall 541 is “front”, and the opposite direction is “rear”. Further, the direction perpendicular to the front-back direction and the vertical direction is defined as the lateral direction.

The wash floor 520 has a drain port 521. The drain port 521 is provided in the vicinity of the center in the front-rear direction of the wash floor 520 and at the end of the wash floor 520 on the bathtub 510 side. The wash floor 520 is provided with a gentle slope toward the drain port 521.

The counter 530, mirror, faucet and shower hose are mounted on the second wall 542. The counter 530 has a counter body and a support member 533 (see FIG. 9). The counter body has, for example, a top plate 531 and a lower cover 532.

The counter 530 is arranged apart from the washing floor 520 upward. A support 533 is attached to the second wall 542 and the counter body is attached to this support. The counter 530 has a substantially rectangular shape that is long in the lateral direction when viewed from above. The width of the counter 530 in the horizontal direction is equal to the width of the wash floor 520 in the horizontal direction.

The water discharger 10 a is provided below the counter 530. The water discharger 10a is arranged at a position separated from the wash floor 520. The water discharger 10a is installed, for example, near the center of the counter 530 in the lateral direction. That is, the water discharger 10a is installed near the center of the washing floor 520 in the lateral direction. As a result, the wash water is easily discharged to the entire wash floor 520.

FIG. 1 shows a side view of the vicinity of the counter 530 in which the water discharger 100 is installed. For example, the water discharger 10 a is provided so as to protrude downward from the lower cover 532.

A water supply pipe 51 and a hot water supply pipe 52 are provided outside the bathroom 500 (for example, behind the second wall 542). The water supply pipe 51 is connected to a water pipe (not shown). Tap water is supplied from the water supply pipe 51 to the water discharge device 100.

Inside the counter 530 (between the top plate 531 and the lower cover 532), a strainer 53a, a solenoid valve 54a, a solenoid valve 54b, a pressure regulating valve 55, a vacuum breaker 57, a check valve 56, and a check valve 56 are provided. A bacterial water production unit 20, a strainer 53b, and a control unit 30 are provided. The strainer 53a is connected to the water supply pipe 51. Downstream of the strainer 53a, the tap water flow path is branched into two.
In one flow path on the downstream side of the strainer 53a, the solenoid valve 54b, the pressure regulating valve 55, the vacuum breaker 57, the check valve 56, the sterilized water generating unit 20, and the strainer 53b are sequentially connected from the upstream side.

In the embodiment, at least a part of the strainers 53 a and 53 b, the solenoid valves 54 a and 54 b, the pressure regulating valve 55, the vacuum breaker 57, the check valve 56, the sterilized water generation unit 20 and the control unit 30 is the counter 530. It may be provided outside or outside the bathroom 500. For example, as shown in FIG. 2A, the control unit 30 may be provided outside the bathroom 500.

The supply of tap water to the downstream side is controlled by opening and closing the electromagnetic valve 54b. The solenoid valve 54b performs an operation of opening the passage of tap water or an operation of closing the passage of tap water.

The pressure regulating valve 55 controls the pressure of the supplied tap water. As a result, the flow rate of tap water supplied to the sterilized water generation unit 20 can be adjusted. By adjusting the flow rate of tap water supplied to the sterilized water generation unit 20, the flow rate of sterilized water supplied to the water discharge unit 10a is adjusted. The flow rate may be adjusted using the solenoid valve 54b.

The sterilized water production unit 20 is an electrolytic cell having an anode and a cathode. The sterilized water generator 20 applies a voltage between the anode and the cathode to electrolyze tap water flowing between the anode and the cathode. As a result, the sterilized water generation unit 20 denatures tap water to generate sterilized water.

The sterilized water is, for example, water containing hypochlorous acid. Since tap water contains chloride ions, electrolysis of the chloride ions produces hypochlorous acid. As a result, the electrolyzed water changes into a liquid containing hypochlorous acid.

The sterilized water may be metal ion water (for example, water containing metal ions such as silver ions, copper ions or zinc ions) or water containing ozone. For example, when tap water is electrolyzed, acid (H ⁺ ) is consumed at the cathode and the pH increases near the cathode. That is, alkaline water is generated in the vicinity of the cathode. On the other hand, alkali (OH ⁻ ) is consumed at the anode, and the pH drops near the anode. That is, acidic water is generated near the anode. By changing the flow rate in the sterilized water generation unit 20, the concentration of the component contained in the sterilized water can be controlled. The sterilized water generating unit 20 is not limited to the electrolytic cell. For example, the sterilized water may be sterilized water generated by dissolving a sterilizing agent in tap water.

The sterilized water generated in the sterilized water generation unit 20 is supplied to the water discharge unit 10a.
On the other hand, the other flow path on the downstream side of the strainer 53a is connected to the water discharger 10a via the electromagnetic valve 54a. Tap water is supplied to the water discharger 10a by opening the solenoid valve 54a.
The wash water (sterilized water and tap water) supplied to the water discharger 10a is discharged from the water discharger 10a onto the washing floor 520. Accordingly, the wash floor 520 can be washed.
In the embodiment, the flow path from the solenoid valve 54b to the water discharger 10a may not necessarily be provided, and may not operate during water discharge. The wash water discharged by the water discharger 10a may be sterilized water or tap water (including hot water).

The position of the water discharger 10a can be changed so as to change the region on the wash floor 520 where the wash water is discharged. In the specification of the application, the fluctuation of the position of the water discharger 10a is at least one of rotation and translation of the water discharger 10a. The fluctuation of the position of the water discharger 10a also includes the case where a part of the water discharger 10a is fixed and another part rotates or translates.
In this example, the water discharger 10a has a motor 17, for example. The motor 17 is, for example, a stepping motor. As will be described later, the water spouting section 10a can be rotated by the motor 17 to change the direction in which the wash water is spouted.

The control unit 30 is connected to the solenoid valves 54a and 54b, the sterilized water generation unit 20, and the water discharge unit 10a (motor 17). The control unit 30 controls the operations of the electromagnetic valves 54a and 54b, the sterilized water generating unit 20, and the water discharge unit 10a, thereby controlling the form in which the wash water is discharged (water discharge method, spraying method).

For example, the solenoid valves 54a and 54b open and close the flow path of tap water based on a signal from the control unit 30. This controls the flow rate of tap water supplied to the downstream side. In addition, the sterilized water generation unit 20 switches ON/OFF of the electrolytic cell based on the signal from the control unit 30. The water discharger 10a changes the rotation angle and the rotation speed based on the signal from the controller 30. In this way, the control unit 30 causes the concentration of the sterilized water, the instantaneous flow rate of the wash water discharged (flow rate per unit time), the total amount of wash water discharged, and the water discharge method such as the discharge direction of the wash water. Can be controlled.

As shown in FIG. 2A, the operation unit 35 connected to the control unit 30 is provided inside the bathroom 500 or outside the bathroom 500. The user of the water spouting device 100 can operate the operation of the water spouting device by using the operation unit 35.

The easiness of soiling of the wash floor 520 and the easiness of flowing wash water may vary depending on the site of the wash floor 520. Therefore, the control unit 30 changes the water discharge method of the cleaning water according to the angle at which the water discharge unit 10a is rotated (the direction in which the cleaning water is discharged). As a result, optimal water discharge can be performed according to the site of the floor of the washroom. As a result, the wash floor can be efficiently washed with a smaller amount of wash water.

FIG. 3A is a plan view illustrating the water discharger of this embodiment. FIG. 3B is a sectional view taken along the line AA shown in FIG.
The water discharge part 10a has a first water storage part 14a, a second water storage part 14b, a first water discharge port 11a, and a second water discharge port 12a. The first water outlet 11a is a hole that connects the inside and the outside of the first water storage section 14a. The second water outlet 12a is a hole that connects the inside and the outside of the second water storage portion 14b. The tap water that has passed through the electromagnetic valve 54a is supplied into the first water storage section 14a and is discharged from the first water discharge port 11a. The sterilized water generated by the sterilized water generation unit 20 is supplied into the second water storage unit 14b and discharged from the second water discharge port 12a.

FIG. 4(a) is a perspective view showing a state in which disinfecting water is spouted as wash water from the second spout 12a, and FIG. 4(b) is a tap water as wash water from the first spout 11a. It is a perspective view showing how water is discharged.

4C and 4D are plan views of the states shown in FIGS. 4A and 4B, respectively, as seen along the X direction in the drawing. In this way, the wash water is fan-shaped or triangular in shape that spreads in the Z direction perpendicular to the X direction, and is discharged from each of the first water outlet 11a and the second water outlet 12a.

4(e) and 4(f) are plan views of the states shown in FIGS. 4(a) and 4(b) as seen along the Z direction. The spread of the wash water discharged when viewed along the Z direction is narrower than the spread of the wash water discharged when viewed along the X direction. For example, the first water discharge port 11a and the second water discharge port 12a respectively discharge cleaning water in a line shape when viewed along the Z direction. By the shapes of the first water discharge port 11a and the second water discharge port 12a, it is possible to adjust how the discharged wash water spreads.

Further, the water discharger 10a has a shaft 10x extending in the Z direction. In this example, the water discharger 10a is arranged such that the shaft 10x is substantially parallel to the vertical direction (vertical direction). The water discharger 10a receives the driving force of the motor 17 and can rotate about the shaft 10x. Since the water discharger 10a discharges the wash water in the direction intersecting the axis 10x, the region where the wash water is discharged can be changed by the rotation of the water discharger 10a. By using rotation to change the position of the water discharger 10a, the structure and control of the water discharger 10a can be simplified. Further, when viewed from above, the maximum water discharge distance of the water discharge portion 10a is longer than the longest distance between the water discharge portion 10a and the wall surface 540.

In the specification of the present application, the "water discharge direction" means the direction in which the wash water is discharged when viewed along the axis 10x. That is, in this example, the "water discharge direction" is the direction in which the wash water is discharged when viewed from above. When the wash water spreads in a plurality of directions and is discharged when viewed from above, the center of the plurality of directions can be defined as the “water discharge direction”. Alternatively, when the cleaning water is discharged in a fan-shaped or triangular shape centered on the water outlets 11a and 12a when viewed from above, the direction that roughly bisects the fan-shaped or triangular range is defined as the "water-jet direction". Can be

Next, an example of the water discharge operation of the water discharge device 100 will be described with reference to FIG.
FIG. 5: is a top view which illustrates operation|movement of the water discharge apparatus which concerns on this embodiment.
In this example, the water discharger 10a discharges tap water. The control unit 30 controls the fluctuation (rotation) of the position of the water discharge unit 10a. The range in which the water discharger 10a moves is divided into a plurality of ranges (position change ranges), and suitable water discharge is performed for each position change range.

For example, the water discharger 10a can rotate about the axis 10x within a range of about 300° to 360°. When the position fluctuation of the water discharger 10a is rotation, the position fluctuation range of the water discharger 10a is determined by the range of the rotation angle about the axis 10x. For example, the range in which the water discharger 10a moves includes the ranges De1 to De4 (position variation range) as shown in FIG.

The water discharger 10a discharges wash water (tap water) to the area Re1 on the wash floor 520 in the range De1. That is, when the rotation angle of the water discharger 10a is within the range De1, the water discharger 10a discharges water onto the region Re1 while rotating in the direction of the arrow. The area Re1 is an area including a part of the wash floor 520 adjacent to the third wall 543.

After that, the water discharger 10a discharges water onto the region Re2 in the range De2 while rotating in the direction of the arrow. The area Re2 is an area including the portion of the wash floor 520 adjacent to the first wall 541.
Similarly, thereafter, the water discharger 10a discharges water on the region Re3 in the range De3 and then discharges water on the region Re4 in the range De4. Regions Re3 and Re4 are regions of the washing floor 520 that include a portion adjacent to the bathtub 510. The region Re3 is located closer to the first wall 541 than the region Re4.

In the plan view shown in FIG. 5, the distance from the water discharger 10a along the water discharge direction in the range De2 to the wall surface (for example, the distance Lb) is the distance from the water discharger 10a along the water discharge direction in the range De1 to the wall surface (for example, the distance Lb). It is longer than the distance La). The region Re2 includes more portions far from the water discharger 10a than the region Re1 and is wider than the region Re1.

In this case, the control unit 30 controls the water discharger 10a so that the total water discharge amount in the range De2 is larger than the total water discharge amount in the range De1. For example, the water discharge amount per unit time of the water discharge unit 10a is set to be constant, and the average rotation speed (°/sec) of the water discharge unit 10a in the range De2 is set lower than the average rotation speed of the water discharge unit 10a in the range De1. The amount of wash water discharged can be controlled for each region on the wash floor 520 by a simple control of controlling the average rotation speed.

In the case of washing, not only the washing water directly reaching the washing floor 520 from the water discharge part 10a but also the washing water flowing on the washing floor 520 after hitting the wall surface can be used. When the water discharger 10a discharges water in the range De1, the distance to the wall surface along the water discharge direction is shorter than when water is discharged in the range De2, so the amount of wash water flowing on the wash floor 520 after hitting the wall surface is relatively large. Many. Therefore, as described above, even if the water discharge amount of the water discharge part 10a in the range De1 is smaller than the water discharge amount of the water discharge part 10a in the range De2, the amount of wash water flowing over the region Re1 can be secured. Therefore, the region Re1 can be cleaned even if the total water discharge amount in the range De1 of the water discharger 10a is relatively small.

Further, when the rotation angle of the water discharger 10a is within the range De4, the distance from the water discharger 10a to the wall surface along the water discharge direction is relatively short. Therefore, the average rotation speed of the water discharger 10a in the range De4 is set to be high, and the total water discharge amount in the range De4 is set to be small. Similarly, the average rotation speed of the water discharger 10a in the range De3 is set to medium speed and the total amount of water discharge in the range De3 is set to medium, according to the distance to the wall surface along the water discharge direction.

As described above, by changing the water discharge form according to the position variation range of the water discharge unit 10a, it is possible to prevent the water discharge unit 10a from discharging more wash water than necessary, and the water is discharged to the entire wash floor 520. The total amount of wash water can be reduced.

When the wash water is tap water, it is desirable to discharge water from the upstream side of the drain gradient of the wash floor 520. For example, as described above, after water is discharged to the area Re1 located upstream, water is discharged to the area Re2 located downstream. Also, within each position variation range of the water discharger 10a, the water is discharged while rotating the water discharger 10a in the direction shown by the arrow in the figure, whereby the wash water is first discharged to the upstream side. For example, the rotation direction of the water discharger 10a in the range De4 is opposite to the rotation direction of the water discharger 10a in the range De1. As described above, a flow of washing water is formed from the upstream side to the downstream side on the washing floor 520, and the dirt can be washed out to the drain port 521.

Further, in this example, when the cleaning water is spouted to the region Re2 on the downstream side, the average rotation speed of the water spouting portion 10a is set relatively low. As a result, in the region Re2, after the cleaning water flows from the upstream region Re1, the cleaning water directly reaches from the water discharger 10a. That is, it is possible to prevent the wash water that directly reaches the region Re2 from the water discharger 10a from colliding with the wash water that flows from the upstream region Re1. Therefore, it is possible to prevent the flow of the wash water on the wash floor 520 from being obstructed and to smoothly flow the dirt on the wash floor 520 to the drain port 521.

6A and 6B are plan views illustrating the water discharge operation of another water discharge device according to this embodiment. This example is different from the examples described with reference to FIGS. 1 to 5 in the arrangement and position variation of the water discharger 10a. Also in this example, the water discharger 10a discharges tap water as wash water.
FIG. 6A shows the washing floor 520 viewed from above.
FIG. 6B shows a state in which the washing floor 520 and the water discharger 10a are viewed from the side along the direction of the arrow AA shown in FIG. 6A.

As shown in FIG. 6A, in this example, the water discharger 10 a is provided at a position close to the second wall 542 and the third wall 543. Further, the first and second water discharge ports 11a and 12a are arranged rotated by 90° as compared with the case of FIG. That is, the wash water (W) discharged from the water discharger 10a spreads in a fan shape or a triangular shape when viewed from above as in FIG. 6(a), and when viewed from the side as in FIG. 6(b). It has a line shape extending obliquely downward.

Further, in this example, as shown in FIG. 6B, the water discharger 10a is arranged so that the shaft 10x extends in a substantially horizontal direction. The water discharger 10a can be rotated about the shaft 10x by a motor or the like to change the area on the wash floor 520 where the wash water is discharged. The moving range of the water discharger 10a includes ranges Dg1 to Dg3 of rotation angles about the axis 10x.

The water discharger 10a discharges the wash water onto the area Rg1 of the wash floor 520 in the range Dg1. That is, when the rotation angle of the water discharger 10a is within the range Dg1, the water discharger 10a discharges water onto the region Rg1 while rotating in the direction of the arrow.

After that, the water discharger 10a discharges the wash water onto the region Rg2 while rotating in the direction of the arrow in the range Dg2. After that, the water discharger 10a discharges the wash water onto the region Rg3 while rotating in the direction of the arrow in the range Dg3.

The region Rg2 is farther from the water discharger 10a and wider than the region Rg1 as compared with the region Rg1. The boundary between the region Rg1 and the region Rg2 is determined so as to divide the distance from the water discharger 10a to the drain port 521 into approximately two equal parts. The region Rg3 is farther from the water discharger 10a than the region Rg2. The boundary between the region Rg2 and the region Rg3 is determined so as to pass through the drain port 521, for example.

The control unit 30 controls the water discharger 10a so that the total water discharge amount in the range Dg2 is larger than the total water discharge amount in the range Dg1. For example, the amount of water discharged per unit time of the water discharger 10a is fixed, and the average rotation speed of the water discharger 10a in the range Dg2 is lower than the average rotation speed of the water discharger 10a in the range Dg1. As a result, the amount of wash water discharged to the relatively narrow region Rg1 can be reduced, and the amount of wash water discharged to the relatively wide region Rg2 can be increased.

As described above, it is possible to prevent the water discharger 10a from discharging more wash water than necessary and reduce the total amount of wash water discharged to the entire washing floor 520.

The control unit 30 also controls the water discharger 10a so that the total water discharge amount in the range Dg3 is larger than the total water discharge amount in the range Dg2. For example, the amount of water discharged from the water discharger 10a per unit time is fixed, and the average rotation speed of the water discharger 10a in the range Dg3 is set lower than the average rotation speed of the water discharger 10a in the range Dg2.

Further, as described above, when the wash water is tap water, it is desirable to discharge water from the upstream side of the drain gradient of the wash floor 520. For example, after water is discharged to a region Rg1 relatively far from the drain port 521, water is discharged to a region Rg2 relatively close to the drain port 521. As a result, a flow of wash water is formed on the wash floor 520, and dirt can be washed out to the drain port 521.
The control unit 30 also rotates the water discharger 10a in the directions of the arrows indicating the ranges Dg1 to Dg3 even within the range of each rotation angle. That is, water is discharged from a portion farther from the drain port 521 (upstream side of the drain gradient). For example, the rotation direction of the water discharger 10a in the range Dg3 (the direction in which the position changes) is opposite to the rotation direction of the water discharger 10a in the range Dg2. Thereby, the dirt can be smoothly sent to the drain port 521 without being driven to the edge of the wash floor 520.

Further, when the water is discharged to a region far from the water discharge part 10a (a region close to the drainage gradient 521), the fluctuation speed (average rotation speed) of the water discharge part 10a is lowered, thereby obstructing the flow of the wash water from the upstream side. Therefore, dirt can be smoothly flowed to the drain port 521.

In the above example, the positional fluctuation of the water discharger 10a was rotation, but the embodiment is not limited to this. For example, as shown in FIG. 6C, the positional fluctuation of the water discharger 10a may be translation. Similar to FIG. 6B, FIG. 6C shows a side view of the washing floor 520 and the water discharger 10a. In this example, the water discharger 10a similar to that in FIG. 6B does not rotate but translates vertically by a rail, a motor, or the like (not shown).
As a result, it is possible to change the area on the wash floor 520 for discharging the wash water. Note that vertical fluctuation and rotation may be combined as appropriate.
When the fluctuation of the position of the water discharger 10a is translation in the vertical direction, the position fluctuation range of the water discharger 10a is determined by the range of the height of the water discharger 10. For example, the range in which the water discharger 10a moves includes ranges Dh1 to Dh3 as shown in FIG. 6(c).

The water discharger 10a discharges the wash water onto the region Rg1 of the wash floor 520 in the range Dh1. That is, when the height of the water discharger 10a is within the range Dh1, the water discharger 10a discharges water on the region Rg1 while moving upward.

After that, the water discharger 10a discharges the wash water onto the region Rg2 while moving upward in the range Dh2. After that, the water discharger 10a discharges the wash water onto the region Rg3 while moving downward in the range Dh3.

In this case, the control unit 30 controls the water discharger 10a so that the total water discharge amount in the range Dh2 is larger than the total water discharge amount in the range Dh1. For example, the water discharge amount per unit time of the water discharge unit 10a is set to be constant, and the average moving speed (meter/sec) of the water discharge unit 10a in the range Dh2 is set lower than the average moving speed of the water discharge unit 10a in the range Dh1. As a result, the amount of wash water discharged to the relatively narrow region Rg1 can be reduced, and the amount of wash water discharged to the relatively wide region Rg2 can be increased.

Similarly, the control unit 30 controls the water discharger 10a so that the total water discharge amount in the range Dh3 is larger than the total water discharge amount in the range Dh2. For example, the water discharge amount of the water discharge unit 10a per unit time is set to be constant, and the average moving speed of the water discharge unit 10a in the range Dh3 is set lower than the average moving speed of the water discharge unit 10a in the range Dh2.

As described above, it is possible to prevent the water discharger 10a from discharging more wash water than necessary and reduce the total amount of wash water discharged to the entire washing floor 520. Further, dirt on the wash floor 520 can be smoothly discharged to the drain port 521.

Next, a case will be described in which disinfecting water is discharged as washing water.
In the following example, the water discharger 10 shown in FIGS. 7 to 9 is used instead of the water discharger 10a described above. The structure of the water discharger other than this is the same as the description relating to FIGS. 1 to 5.
The water discharger 10 has a rotating shaft extending in a substantially vertical direction, and is installed, for example, in the vicinity of the center in the lateral direction of the counter 530, similarly to the description of the water discharger 10a in FIGS. Also in the following example, the water discharger 10 may discharge tap water instead of the sterilized water.

FIG. 7A and FIG. 7B are schematic views illustrating the water discharger of this embodiment. FIG. 7A is a schematic perspective view of the water discharger 10. FIG. 7B is a schematic cross-sectional view taken along the line A-A′ shown in FIG.

As shown in FIGS. 7A and 7B, the water discharger 10 has a first water discharge outlet 11, a second water discharge outlet 12, and a water storage 13.

The water storage unit 13 has, for example, a cylindrical shape, and can temporarily store the sterilized water supplied to the internal space. The first water outlet 11 and the second water outlet 12 are provided on the side surface of the water storage section 13. The first water outlet 11 is provided above the second water outlet 12.

The space in the water storage section 13 in which the sterilized water is stored communicates with the outside through the first water discharge port 11 and the second water discharge port 12. As a result, the first water discharge port 11 and the second water discharge port 12 discharge the sterilized water accumulated in the water storage unit 13 onto the floor of the washing place. For example, the first spout 11 and the second spout 12 simultaneously discharge the sterilized water. By providing the water storage unit 13, the wash water can be temporarily stored and the water discharge pressure can be increased.

FIG. 8A and FIG. 8B are schematic side views illustrating the state in which the sterilized water is discharged from the water discharge part of the present embodiment. FIG. 8B is an enlarged view of the vicinity of the water discharger 10 of FIG. 8A.

The first water discharge port 11 is provided above the second water discharge port 12. For example, the first water outlet 11 is upward from the horizontal direction, and the second water outlet 12 is downward from the horizontal direction. As a result, the sterilized water discharged from the first water discharge port 11 reaches a region farther from the water discharge unit 10 than the sterilized water discharged from the second water discharge port 12. The first spout 11 is a distant spout that serves a range of the wash floor 520 far from the spout 10. The second spout 12 is a nearby spout that serves a range of the washing floor 520 that is close to the spout 10.

The maximum water discharge distance of the first water discharge port 11 when viewed from above (the longest distance between the position where the disinfected water discharged from the water discharge unit 10 reaches the water discharge unit 10 when there is no obstacle; the range) Is longer than the longest distance between the water discharger 10 and the wall surface 540.

Further, in this example, the direction in which the sterilized water is discharged from the second water outlet 12 is a direction along the direction in which the sterilized water is discharged from the first water outlet 11 when viewed from above. is there. For example, the water discharge direction of the first water discharge port 11 is substantially the same as the water discharge direction of the second water discharge port 12.

Since the diameters of the first water discharge port 11 and the second water discharge port 12 are small, the sterilized water is discharged as, for example, a mist (mist). Such mist-like sterilized water tends to stay on the floor of the washing place. By discharging the disinfecting water in a form having a high retention property, it is possible to secure a time for the disinfecting water to act on the bacteria on the washing floor. Thereby, the washing floor can be sterilized with a smaller amount of sterilized water.

As shown in FIG. 7A, the water discharge part 10 is provided with a groove 11 g along the up-down direction in the vicinity of the first water discharge port 11. The direction in which the disinfected water is spouted from the first spout 11 is controlled by the groove 11g. Similarly, the direction in which the sterilized water is discharged from the second water discharge port 12 is controlled by the groove 12g provided in the vicinity of the second water discharge port 12 and extending in the vertical direction. As a result, as shown in FIG. 8B, the sterilized water is spread from the first spout 11 and the second spout 12 in the vertical direction and spouted.

FIG. 9A and FIG. 9B are schematic diagrams illustrating the rotation of the water discharger according to the present embodiment. FIG. 9A is a schematic plan view of the counter 530 provided with the water discharger 10 and the wash floor 520 as seen from above. FIG. 9B is an enlarged schematic plan view showing the vicinity of the water discharger 10 of FIG. 9A.

The water discharger 10 can rotate around an axis 10x. The shaft 10x is a rotating shaft extending in the vertical direction. The shaft 10x is located substantially at the center of the water discharger 10 when viewed from above. The direction in which the axis 10x extends may be tilted from the complete vertical direction. For example, the vertical component in the direction in which the axis 10x extends may be larger than the horizontal component in the direction in which the axis 10x extends.

The water discharger 10 can rotate from a rotation origin 10s (rotation start position) to a rotation end position 10e. The direction in which the sterilized water discharged from the first water discharge port 11 and the second water discharge port 12 changes depending on the angle at which the water discharge unit 10 rotates. By discharging the sterilized water while the water discharger 10 rotates, the sterilized water is discharged onto the entire washing floor 520.

The water spouting device 100 according to the present embodiment is a rotation that defines a relative position between a position that serves as a reference when the water spouting part 10 rotates (hereinafter, referred to as a “rotation reference” for convenience of description) and the wash floor 520. Further provided is a standard defining means 15. For example, the origin 10s can be used as the rotation reference. The rotation reference defining unit 15 is a unit that defines the rotation reference so as to form a predetermined angle with respect to the wash floor 520.

For example, as shown in FIG. 9B, the water discharger 100 is provided with a rotation reference portion 10p and a rotation reference defining portion 534. Further, the water discharger 10 is provided with a protrusion 10q. As the rotation reference defining means 15, a rotation reference part 10p and a rotation reference defining part 534 can be used.

The rotation reference defining portion 534 is a member whose position is directly or indirectly fixed with respect to the counter 530. The rotation reference defining unit 534 is provided in the counter 530. The rotation reference defining portion 534 is attached to the support member 533 of the counter 530, for example. The rotation reference defining portion 534 may be a member separate from the counter 530, or may be integrally formed with the counter 530.

The rotation reference portion 10p is a member whose position is directly or indirectly fixed with respect to the rotation reference defining portion 534. For example, the rotation reference portion 10p is attached to the rotation reference defining portion 534. As a result, the rotation reference portion 10p is fixed relative to the counter 530.

The protrusion 10q is a member provided on the side surface of the water discharger 10, and rotates with the rotation of the first water discharge outlet 11 and the second water discharge outlet 12. When the water discharger 10 rotates, the protrusion 10q is arranged so as to abut against the rotation reference portion 10p. In this way, the rotation reference portion 10p and the protrusion 10q regulate the rotation of the water discharger 10. Accordingly, the position of the rotation reference portion 10p can be used as the rotation reference. Then, the rotation reference defining unit 534 defines the relative arrangement of the rotation reference and the counter 530.
The rotation reference portion 10p may be a part of the counter 530 or may be integrally formed with the counter 530. In this case, the rotation reference portion 10p also serves as the rotation reference defining portion 534.

For example, when the water discharger is attached to the counter in the bathroom, the rotation reference of the water discharger may deviate from a predetermined position. When changing the sprinkling method of the sterilized water depending on the rotation angle of the water spouting part, if the rotation reference of the water spouting part deviates, there is a possibility that the optimum sprinkling of the sterilized water cannot be performed according to the site. On the other hand, in the embodiment, the rotation reference defining means 15 as described above is provided. The rotation reference defining unit 15 can match the rotation reference of the water discharger 10 with respect to the wash floor 520. Therefore, it is possible to prevent the water discharger 10 from being attached to the counter when the rotation reference is deviated from the predetermined position. As a result, it is possible to surely perform optimum water discharge according to the site of the washing floor.

Generally, the counter is mounted in the bathroom such that the lateral center of the counter is aligned with the lateral center of the short side of the washroom floor. That is, the relative arrangement of the counter and the wash floor is defined in advance. Therefore, in the present embodiment, the position of the water discharger 10 is defined with respect to the counter 530. Specifically, the rotation reference part 10p and the rotation reference definition part 534, whose relative arrangement with the counter 530 is defined, are provided. Thereby, the relative arrangement of the rotation reference and the washing floor 520 can be defined via the counter 530. As a result, it is possible to surely perform optimal water discharge according to each part of the wash floor.

Even if the position where the water discharger 10 is attached to the counter changes depending on the type of the counter, if the rotation reference defining portion 534 is formed in the counter in consideration of the relationship between the center of the counter and the position where the water discharger 10 is attached, It is possible to specify the rotation standard corresponding to the wash floor. As a result, it is possible to perform optimal water discharge according to each part of the wash floor 520, even for various types of counters in which the water discharger 10 is attached at different positions.

Next, an example of the operation of the water discharger 100 when disinfecting the wash floor 520 will be described.

FIG. 10 is a flowchart illustrating the operation of the water discharge device according to this embodiment.
FIG. 11 is a schematic plan view illustrating the operation of the water discharger according to this embodiment.
FIG. 11 shows the rotating operation of the water discharger 10 in each step of the sterilization method using the water discharger 100.
As shown in FIG. 10, first, when the switch of the water discharger 100 is OFF, the electromagnetic valve 54b is closed, and the electrolytic cell (sterilized water producing unit 20) and the motor 17 are OFF.

Here, for example, when the switch of the water spouting device 100 is turned on by the user, an instruction to execute the washing place sterilization mode (sterilized water spouting process described below) is transmitted to the control unit 30. At this time, the control unit 30 first executes the origin finding mode S01 before executing the washing place sterilization mode.

In the origin finding mode S01, the control unit 30 uses the rotation reference defining unit 15 to find the origin of the rotation of the water discharger 10. Here, “origin finding” refers to an operation in which the position (direction) of the water discharger 10 is associated with the rotation reference. Specifically, the control unit 30 turns on the motor 17 (operating state) and rotates the water discharge unit 10 in the direction shown by the arrow A01 in FIG.

FIG. 12A and FIG. 12B are schematic plan views illustrating origin finding in the present embodiment. 12A and 12B show the operation of the water discharger 10.
As shown in FIG. 12A, the angle from the origin 10s to the end position 10e (maximum rotation angle θ1) is, for example, about 300°. In the home search mode S01, the control unit 30 sends a signal to the motor 17 to rotate it by the maximum rotation angle θ1.

As illustrated in FIG. 12B, for example, when the switch of the water discharger 100 is turned on, it is assumed that the angle at which the water discharger 10 rotates from the origin 10s is θ2. At this time, the water discharger 10 first rotates by the angle θ2. As a result, the protrusion 10q of the water discharger 10 strikes the rotation reference portion 10p. Furthermore, in this state, the motor 17 idles by the difference (angle θ3) between the maximum rotation angle θ1 and the angle θ2. This ensures that the direction of the water discharger 10 is aligned with the origin 10s (reference of rotation).

Next, the control unit 30 executes the first sterilized water/water discharge step S02. In the first disinfected water spouting step S02, the solenoid valve 54b is opened and tap water is supplied to the electrolytic cell. Then, the electrolytic cell is turned on to denature tap water and generate sterilized water. The generated sterilized water is discharged from the water discharge part 10 to the wash floor 520. At this time, the control unit 30 turns on the motor 17 and rotates the water discharge unit 10 from the origin 10s to the end position 10e as shown by an arrow A02 in FIG. The water discharger 10 discharges the sterilized water onto the washing floor 520 while rotating.

In addition, in each arrow shown in FIG. 11, when the water discharge part 10 rotates in the direction shown by the broken line, it means that the water discharge part 10 does not discharge the sterilized water. When the water discharger 10 rotates in the direction indicated by the solid line, it indicates that the water discharger 10 discharges the sterilized water.

Next, the water stopping step S03 is executed. In the water stopping step S03, the electromagnetic valve 54b is closed and the electrolytic cell is turned off (stopped state). Further, the motor 17 is also turned off (stopped state).

Next, the control unit 30 executes the origin finding mode S04. In the home search mode S04, the control unit 30 performs the home search of the water discharger 10. The control unit 30 turns on the motor 17 and rotates the water discharge unit 10 from the end position 10e to the origin 10s as shown by an arrow A04 in FIG. At this time, the water discharger 10 does not discharge the sterilized water.

After that, the control unit 30 executes the second sterilized water spouting step S05. In the second sterilized water spouting step S05, the electromagnetic valve 54b is opened and the electrolytic cell is turned on. The controller 30 causes the motor 17 to rotate the water discharger 10. The water discharger 10 discharges the sterilized water while rotating from the origin 10s to the end position 10e as shown by an arrow A05 in FIG. The method of discharging the sterilized water in the second sterilized water/water discharging step S05 may be different from that in the first sterilized water/water discharging step S02. For example, the components and concentrations of the sterilized water discharged in the second sterilized water spouting step S05 may be different from the components and the concentration of sterilized water discharged in the first sterilized water spouting step S02.

Next, the disinfecting water spouting completion step S06 is executed. In the disinfecting water spouting completion step S06, the electromagnetic valve 54b is closed, the electrolytic cell is turned off, and the motor 17 is turned off.

Next, the control unit 30 executes the residual water discharge mode S07. In the residual water discharge mode S07, at least a part of the sterilized water remaining in the flow path of the sterilized water in the water discharge part 10 is discharged. For example, the sterilized water remaining in the flow path from the water storage unit 13 to the first water discharge port 11 or the flow path from the water storage unit 13 to the second water discharge port 12 is discharged. Specifically, the control unit 30 controls the motor 17 to vibrate the water discharge unit 10. The water discharger 10 rotates from the end position 10e to the origin 10s while vibrating, as shown by an arrow A07 in FIG.

For example, when the water discharger 100 is not used, the user's body may hit the water discharger 10 and the angle of the water discharger 10 with respect to the wash floor 520 may be displaced. Even in such a case, according to the embodiment, since the origin is set before the washing place sterilization mode, the discharge of the sterilized water is started in the state where the deviation of the angle is corrected. As a result, optimum water discharge can be stably performed for a long period of time according to the site of the wash floor.

In addition, when the water discharger is used for a long period of time, the movement resistance (resistance when rotating) of the water discharger 10 increases, and the angle of the water discharger 10 with respect to the wash floor 520 from the intended angle during execution of the wash sterilization mode. It may shift. Further, when an obstacle is placed around the water discharger 10, the water discharger 10 may hit the obstacle when the water discharger 10 rotates. Also at this time, the angle of the water discharger 10 with respect to the wash floor 520 may deviate from the intended angle.

On the other hand, in the embodiment, the origin finding mode S04 is executed between the first sterilized water/water discharge step S02 and the second sterilized water/water discharge step S05. That is, the control unit 30 executes the origin finding mode in the middle of the washing place sterilization mode. Thereby, the deviation of the angle of the water discharger 10 with respect to the wash floor 520 can be corrected during the wash sterilization mode. Therefore, it is possible to prevent the sterilized water from being spouted in a state in which the angle of the water spouting section 10 with respect to the washing floor 520 is largely deviated. As a result, optimal water discharge can be stably performed for a long period of time in accordance with the site of the wash floor 520.

Next, the operation of the water discharge device in the first sterilized water/water discharge step S02 will be further described with reference to FIGS. 13 to 15.

FIG. 13 is a time chart explaining the operation of the water discharger according to this embodiment. FIG. 13 shows operations in the first disinfecting water spouting step S02 and the origin finding mode S04. As shown in FIG. 13, in the first sterilized water/water discharge step S02, the sterilized water is continuously discharged from the water discharge part 10. Then, in the origin finding mode S04 of the water stopping step S03, the sterilized water is not discharged from the water discharge part 10.

In the "rotation of the water discharge part" of the time chart, "1" represents that the water discharge part 10 is rotating from the origin 10s toward the end position 10e (normal rotation operation), and "0" is the water discharge part 10. Represents that the rotation is stopped, and “−1” represents that the water discharger 10 is rotating from the end position 10e toward the origin 10s (reversing operation).
As shown in FIG. 13, the water discharger 10 repeats rotation and stop. In the first sterilized water/water discharge step S02, the water discharger 10 intermittently rotates in the direction from the origin 10s to the end position 10e. In the origin finding mode S04, the water discharger 10 intermittently rotates in the direction from the end position 10e toward the origin 10s.

FIG. 14 is a schematic plan view illustrating the operation of the water discharger according to this embodiment.
The area A1 represents an area where the sterilized water is discharged during a certain period t1 when the water discharger 10 stops rotating. The area A2 represents an area in which the sterilized water is discharged during the period t2 when the water discharger 10 stops rotating after the period t1. As shown in FIG. 14, a part of the area A2 overlaps with a part of the area A1. In this way, the water discharger 10 intermittently rotates from the origin 10s to the end position 10e.

Further, in the present embodiment, the water spouting device 100 changes the amount of sterilized water spouted and the rotation speed of the water spouting part 10 according to the site of the wash floor 520. This will be described below.

FIG. 15A and FIG. 15B are schematic plan views illustrating the operation of the water discharger according to this embodiment.
15A is a schematic plan view illustrating the water discharger 10, and FIG. 15B is a schematic plan view illustrating the wash floor 520.

As shown in FIG. 15A, in this example, the angle at which the water discharger 10 rotates (rotation angle) is divided into five different ranges D1 to D5. FIG.15(b) represents area|region R1-R5 of the washing floor 520 corresponding to each of range D1-D5.

For example, in the state ST1 where the rotation angle is within the range D1, the sterilized water is discharged to the region R1. In the state ST2 in which the rotation angle is within the range D2, the sterilized water is discharged onto the region R2.

The distance from the water discharge portion 10 along the water discharge direction to the wall surface 540 in the state ST1 is shorter than the distance from the water discharge portion 10 along the water discharge direction to the wall surface 540 in the state ST2. At this time, as shown in FIG. 13, the control unit 30 causes the total amount of the sterilized water discharged in the state ST1 to be smaller than the total amount of the sterilized water discharged in the state ST2.

Similarly, in the state ST3 in which the rotation angle is within the range D3, the sterilized water is discharged to the region R3. The distance from the water discharge part 10 along the water discharge direction to the wall surface 540 in the state ST3 is longer than the distance from the water discharge part 10 along the water discharge direction to the wall surface 540 in the state ST2. At this time, the control unit 30 makes the total amount of the sterilized water discharged in the state ST3 larger than the total amount of the sterilized water discharged in the state ST2.

As described above, in the embodiment, the total amount of sterilized water discharged in the rotation angle region in which the distance between the water discharger 10 and the wall surface 540 is relatively short is the distance between the water discharger 10 and the wall surface 540. Is smaller than the total amount of sterilized water discharged in a relatively long rotation angle region.

In the state ST4 in which the rotation angle is within the range D4, the sterilized water is discharged onto the region R4. The distance from the water discharger 10 along the water discharge direction to the wall surface 540 in the state ST4 is the same as the distance from the water discharger 10 along the water discharge direction to the wall surface 540 in the state ST2. The distance between the region R4 and the drain port 521 is longer than the distance between the region R2 and the drain port 521. That is, the region R4 is located on the upstream side of the wash floor 520 with respect to the region R2. In this case, the control unit 30 causes the total amount of the sterilized water discharged in the state ST2 to be smaller than the total amount of the sterilized water discharged in the state ST4.

As described above, when the distance between the water discharger 10 and the wall surface 540 is the same, the amount of the sterilized water discharged to the downstream side of the drainage gradient of the washing floor 520 is the upstream side of the drainage gradient of the washing floor 520. It is less than the amount of sterilized water discharged to.

For example, the instantaneous flow rate of the sterilized water discharged from the water discharger 10 is constant. Then, the control unit 30 changes the average rotation speed of the water discharge unit 10 according to the distance from the water discharge unit 10 to the wall surface 540 along the water discharge direction. This makes it possible to change the total amount of sterilized water discharged according to the site of the wash floor. For example, the average rotation speed of the water discharger 10 in the state ST1 is higher than the average rotation speed of the water discharger 10 in the state ST3. As a result, the total amount of the sterilized water discharged in the state ST1 becomes smaller than the total amount of the sterilized water discharged in the state ST3.

As shown in FIG. 13, when the water discharger 10 repeats rotation and stop, the average rotation speed can be changed by changing the length of time that the water discharger 10 stops. For example, the average rotation speed can be changed by keeping the angle and time for the water discharger 10 to rotate at a time and changing the time period in which the rotation operation is performed. For example, the cycle of the rotating operation in the state ST1 is shorter than the cycle of the rotating operation in the state ST3.

In the time chart, the “water discharge state” is a schematic plan view showing the direction in which the sterilized water is discharged in each range of the rotation angle. In addition, the arrow in the plan view represents the flow of the sterilized water flowing from the water discharger 10 onto the washing floor 520 after hitting the wall surface 540. The direction of the arrow schematically represents the flow direction of the sterilized water, and the size of the arrow schematically represents the amount of the sterilized water. In addition, in the time chart, “floor surface state” represents the amount of sterilized water existing on the wash floor 520 in each state in gray scale. This gray scale indicates that the darker the color (closer to black), the larger the amount of sterilized water.

As described above, the maximum water discharge distance at which the water discharge unit 10 discharges the sterilized water is longer than the maximum distance between the water discharge unit 10 and the wall surface 540. By rotating the water discharge part 10 as described above, it becomes possible to discharge the sterilized water to the entire washing floor 520, and it is possible to sterilize the entire washing floor.

However, when the water discharger 10 is rotated, the distance between the water discharger 10 and the wall surface 540 along the water discharge direction changes. In this state, if water is discharged in the same direction in all directions, the disinfecting water will be excessive on the wash floor 520 due to the change in the distance between the water discharge part 10 and the wall surface 540 along the water discharge direction. There will be an area where water is discharged. Therefore, a large amount of sterilized water is required.

On the other hand, not only the sterilized water that directly reaches the washing floor 520 from the water discharge part 10 but also the sterilized water that flows on the washing floor 520 after hitting the wall surface 540 has a sterilizing effect. Therefore, the sterilization water flowing against the wall surface 540 is also used for sterilization, so that the entire washing floor 520 can be sterilized with a small amount of the sterilization water.

For example, as in the state ST1, when the distance between the water discharger 10 and the wall surface 540 along the water discharge direction is short, the sterilized water that is discharged from the water discharger 10 and hits the wall surface 540 and then flows onto the washing floor 520. Is relatively large. Therefore, even if the total amount of the sterilized water discharged in the state ST1 is reduced, the total amount of the sterilized water supplied per unit area can be maintained. Even if the total amount of the disinfecting water discharged in the state ST1 is reduced, the disinfecting effect can be obtained.

Therefore, according to the embodiment, when the distance from the water discharge part 10 to the wall surface 540 along the discharge direction of the sterilized water is short, it is possible to prevent unnecessary sterilized water from being discharged. As a result, the total amount of sterilized water discharged over the entire washing floor 520 can be reduced.

Furthermore, in the embodiment, when the distance from the water discharge part 10 to the wall surface 540 along the discharge direction of the sterilized water is the same, the amount of the sterilized water discharged to the upstream side of the wash floor 520 is the same as that of the wash floor 520. The amount is smaller than the amount of sterilized water discharged to the downstream side. The sterilized water discharged on the upstream side of the washing floor 520 flows to the downstream side of the washing floor 520. Therefore, it is possible to sterilize the downstream side of the washing floor 520 by using the sterilized water discharged on the upstream side of the washing floor 520. As a result, even if the amount of sterilized water discharged to the downstream side of the washing floor 520 is reduced, the entire washing floor 520 can be sterilized.

Further, a method of changing the instantaneous flow rate of the sterilized water when changing the amount of the sterilized water discharged according to the site on the wash floor 520 can be considered. The instantaneous flow rate of the sterilized water discharged from the water discharge unit 10 depends on the instantaneous flow rate of the sterilized water generation unit 20. However, if the instantaneous flow rate in the sterilized water producing unit 20 is changed, the concentration of the components of the sterilized water produced in the sterilized water producing unit 20 will change. On the other hand, in the embodiment, the average rotational speed of the water discharger 10 is changed while keeping the instantaneous flow rate of the sterilized water constant. This makes it possible to change the total amount of the sterilized water discharged into a predetermined range of the wash floor 520 while keeping the concentration of the sterilized water constant.

When the average rotation speed of the water discharger 10 is changed, if the rotation speed is made too fast, the torque may be insufficient and the rotation may be defective. On the other hand, in the embodiment, the control unit 30 switches between a state in which the water discharger 10 is in process and a state in which the water discharger 10 stops rotating. Then, the average rotation speed is changed by changing the length of time that the water discharger 10 stops rotating. This makes it possible to prevent problems such as insufficient torque.

Next, the operation of the water discharger 100 in the residual water discharge mode S07 will be further described with reference to FIGS. 16 and 17.

FIG. 16 is a flowchart illustrating the operation of the water discharge device according to this embodiment. FIG. 17 is a time chart for explaining the operation of the water discharger according to this embodiment.

As shown in FIGS. 16 and 17, the residual water discharge mode S07 has a first vibrating step S17 and a second vibrating step S27 executed after the first vibrating step S17.

As shown in FIG. 17, in the first vibrating step S17, the water discharger 10 repeats rotation and stop. The water discharger 10 intermittently rotates from the end position 10e to the origin 10s. As a result, the water discharger 10 vibrates. This vibration can reduce (break) the surface tension of the sterilized water remaining in the water discharge part 10. As a result, the sterilized water remaining in the flow path in the water discharger 10 is discharged.

Such residual water discharge mode S07 is executed immediately after the washing place sterilization mode (second sterilized water spouting step S05) is executed. Immediately after the washing place sterilization mode is executed, a water film is formed on the washing place floor by the sterilized water. Therefore, the sterilized water discharged in the residual water discharge mode S07 falls on the water film.

When a small amount of the sterilized water is discharged on the wash floor 520, the sterilized water becomes polka-dot-shaped residual water and is difficult to flow to the drain port. On the other hand, when the sterilized water is in the form of a film, the sterilized water easily flows to the drain port along the drain gradient of the wash floor 520.

In the embodiment, the sterilized water discharged from the water discharge part is dropped on the water film. Thereby, the sterilized water discharged from the water discharge part can be made to flow to the drain port together with the sterilized water forming the water film. Therefore, even if the diameter of the spout is reduced in order to spout the disinfected water in the form of spout with high retention, residual water will be generated on the wash floor after a long time has passed since the end of the operation of the spout device. Can be prevented.

Further, in the first vibrating step S17, the water discharger 10 is rotated from the end position 10e to the origin 10s. That is, the water discharger 10 is vibrated while changing the position where the sterilized water remaining in the water discharger 10 falls. As a result, it is possible to increase the plane area of the region where the disinfected water falls on the washing floor 520. Therefore, it is possible to increase the possibility that the sterilized water that has dropped from the water discharge unit 10 and the film-shaped sterilized water on the washing floor 520 are in contact with each other. As a result, the sterilized water discharged from the water discharger 10 can be more reliably guided to the drain port together with the sterilized water forming the water film.

In the second vibration process S27, the control unit 30 causes the water discharge unit 10 to generate a vibration different from the vibration generated in the water discharge unit 10 in the first vibration process S17.

Due to the different vibrations, the sterilized water that could not be discharged in the first vibration step S17 can be discharged in the second vibration step S27. As a result, the amount of sterilized water remaining in the water discharger 10 can be further reduced.

For example, in the second vibration step S27, the control unit 30 moves the positions of the water outlets (the first water outlet 11 and the second water outlet 12) in a plurality of directions. That is, as shown in FIG. 17, the normal rotation operation and the reverse operation are alternately repeated.

In the second vibrating step, such a normal rotation operation and a reversal operation are repeated after the protrusion 10q hits the rotation reference portion 10p. Therefore, in the second vibrating step, the range of movement of the water outlet is narrower than the range of movement of the water outlet in the first vibrating step. Then, every time the forward rotation operation and the reverse operation are repeated, the protrusion 10q hits the rotation reference portion 10p. Therefore, in the second vibrating process, stronger shaking occurs in the water discharge port than in the first vibrating process. This makes it possible to further reduce the amount of sterilized water remaining in the water discharge part.

Further, in the embodiment, the control unit 30 performs the control in which the water spouting unit 10 spouts tap water onto the washing floor 520 as in the description with reference to FIG. You may perform the control which spouts germ water from the water spout part 10 on the washing floor 520. The sterilized water can be effectively used by flushing the stains attached on the wash floor 520 with tap water and then discharging the sterilized water on the wash floor 520.

Next, another embodiment of the present invention will be described with reference to the drawings.
18(a) and 18(b) are schematic plan views illustrating a water discharger according to another embodiment of the present invention.

FIG. 18A is a schematic plan view of the counter 530a provided with the water discharger 10 and the wash floor 520 as seen from above. FIG. 18B is an enlarged schematic plan view showing the vicinity of the water discharger 10 of FIG. 18A.

In this example, the shape of the counter 530a provided with the water discharger 10 is different from the shape of the counter 530 described above. Along with this, the relative disposition of the wash floor 520 and the water discharger 10 is different from the example shown in FIG. 9, for example.

The rotation reference defining portion 534, which is the rotation reference defining means 15, is attached to the support member 533 located at the lateral end of the counter 530a. Therefore, the water discharger 10 is located not at the center of the counter 530a in the lateral direction but at the end.

That is, in this example, the water discharger 10 is provided not at the vicinity of the center of the wash floor 520 in the horizontal direction but at the end of the wash floor 520 in the horizontal direction. Other than this, the water discharger shown in FIG. 18 is the same as the water discharger 100 described in FIGS. 7 to 17.

As described above, even if the position where the water discharger 10 is attached to the counter is changed in this way, the rotation reference defining portion 534 is attached to the counter in consideration of the relationship between the center of the counter and the position where the water discharger 10 is attached. If formed, a rotation standard corresponding to the wash floor can be defined. As a result, optimal water discharge can be performed according to each part of the wash floor 520.

Even in this case, as shown in FIG. 18A, the average rotation speed of the water discharger 10 is changed according to the distance from the water discharger 10 to the wall surface 540 along the water discharge direction. This makes it possible to change the total amount of sterilized water discharged according to the site of the wash floor 520. In this way, optimal water discharge can be performed according to each part of the wash floor 520.
