  Aspects of the present invention generally relate to a washroom water spouting device.

  For example, dirt such as soaps and shampoos used to clean the human body and reds (proteins, carbohydrates, fats, salts, etc.) generated from the human body adhere to the bathroom floor. A cleaning device for sterilizing bacteria caused by such dirt has been proposed.

  In the cleaning apparatus disclosed in Patent Document 1, a water discharger capable of discharging water is provided below a counter in a bathroom. In such a cleaning apparatus, the sterilizing water is discharged onto the washing floor while rotating the water discharger. Thereby, the whole washing-room floor can be disinfected.

JP 2008-168230 A

  In the washing floor, the degree of dirt and the ease of water flow vary depending on the location of the washing floor. For this reason, in order to wash or disinfect the washing floor with less water, it is preferable to change the water spraying method (instantaneous flow rate, water discharge mode, total flow rate, etc.) according to the rotation angle of the water discharger.

  However, for example, when the water discharger is attached to a bathroom, there is a possibility that the position (rotation reference) serving as a reference for rotation of the water discharger may deviate from a predetermined position. When changing the water spraying method according to the rotation angle of the water discharger, if the rotation reference of the water discharger is shifted, there is a risk that the optimal water spraying method depending on the region cannot be performed.

  The present invention has been made based on the recognition of such a problem, and in changing the way of watering depending on the rotation angle of the water discharger, the rotation reference of the water discharger is shifted, so that it is optimal for the part of the washing floor. It aims at providing the washing place water discharging apparatus which can prevent that the method of watering becomes impossible.

  1st invention is a washing place water discharging apparatus which wash | cleans or disinfects the washing place floor of a bathroom, Comprising: The water discharging part which rotates centering on the rotating shaft extended in a perpendicular direction, and discharges the said water on a washing place floor, The said water discharging part A control unit that changes the water discharge method according to the angle of rotation of the water discharger, and a rotation reference defining unit that defines the rotation reference of the water discharger to be a predetermined angle with respect to the washing floor. It is the washing place water discharging apparatus characterized by the above.

  According to this washing place water discharging apparatus, since the water discharging method (how to sprinkle) is changed according to the angle at which the water discharging section rotates, optimal water discharging can be performed according to the part of the washing floor. Thereby, the washing floor can be efficiently washed or sterilized with a smaller amount of water. Moreover, the rotation reference | standard of a water discharge part can be match | combined with a washing-room floor by a rotation reference prescription | regulation means. For this reason, it can prevent that the rotation reference | standard of a water discharging part shifts | deviates from a predetermined position. Thereby, optimal water discharge can be reliably performed according to the site | part of a washroom floor.

  According to a second invention, in the first invention, the water discharger includes a support member attached to a wall surface standing around the washing floor, and a counter body attached to the support member The rotation reference defining means includes a rotation reference defining portion disposed at a position where the water discharge portion abuts when the water discharge portion rotates, the rotation reference defining portion being integrally formed with the counter, or with respect to the counter A washing place water discharging apparatus, which is provided in a separate member fixed to have a predetermined arrangement.

  According to this washing place water discharge device, by forming the rotation reference defining part on the counter, the optimum water discharge according to the part of the washing place floor corresponding to each of the various counters at which the water discharge part is attached to each other. It can be carried out.

  According to a third aspect, in the second aspect, the control unit uses the rotation reference defining means to determine the origin of rotation of the water discharger, and the controller supplies water to the washing floor from the water discharger. A washing place water discharge mode to be discharged, and when the execution instruction for the washing place water discharge mode is issued, the execution of the washing place water discharge mode is started after the origin search mode is executed. It is a water discharge device.

  According to this washing place water discharging apparatus, even when the user's body hits the water discharging section when the washing area water discharging apparatus is not used and the angle of the water discharging section with respect to the washing floor is shifted, the origin is set before the washing area water discharging mode. Take out. For this reason, the discharge of water is started in a state where the angle deviation is corrected. Thereby, optimal water discharge can be performed according to the site | part of a washroom floor stably for a long term.

  According to a fourth aspect, in the second aspect, the control unit is configured to perform an origin search mode in which the origin of rotation of the water discharger is determined using the rotation reference defining means, and water is supplied from the water discharger to the wash floor. The washing place water discharging device is capable of executing a washing place water discharging mode to be discharged, and executing the origin search mode during the execution of the washing place water discharging mode.

  According to this washing area water discharge device, the movement resistance of the water discharge section increases due to long-term use, and even if the angle of the water discharge section with respect to the wash floor is shifted during execution of the wash area water discharge mode, Since the discharge mode is performed, the deviation of the angle of the water discharger can be corrected during the washing area water discharge mode. For this reason, it can prevent that water is discharged in the state which the angle with respect to the washing-room floor of a water discharging part shifted | deviated large. Thereby, optimal water discharge can be performed according to the site | part of a washroom floor stably for a long term.

  According to the aspect of the present invention, when changing the water spraying method according to the rotation angle of the water discharger, the optimal water spraying method according to the site of the wash floor cannot be achieved by shifting the rotation reference of the water discharger. A washing place water discharger that can be prevented is provided.

Drawing 1 is a mimetic diagram which illustrates the sterilization water spouting device for bathroom washing places concerning an embodiment of the invention.
As shown in FIG. 1, a sterilizing water spouting device for bathroom washing place according to an embodiment of the present invention (hereinafter simply referred to as “sterilizing water spouting device”) 100 is a sterilizing water spouting unit. 10, a sterilized water generation unit 20, and a control unit 30. The sterilizing water spouting device 100 is a device that is installed in a bathroom and sterilizes a bathroom floor.

First, an example of a bathroom in which the sterilizing water spouting device 100 is installed will be described.
Fig.2 (a) and FIG.2 (b) are typical perspective views showing the bathroom in which the sterilization water discharging apparatus for bathroom washing places concerning this embodiment was installed.
As shown to Fig.2 (a), the bathroom 500 in which the disinfection water discharging apparatus 100 is installed is provided with the 1st-4th walls 541-544, the bathtub 510, the washing-room floor 520, and the counter 530. Yes. Furthermore, the bathroom 500 is appropriately provided with a mirror, a water tap, a shower hose, and the like. FIG. 2B is a schematic perspective view in which the vicinity of the counter 530 is enlarged.

  The 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 facing 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 washing floor 520. For example, the bathtub 510 is disposed in contact with 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 washroom floor 520 is surrounded by wall surfaces 540 standing upright in the periphery. Here, the “wall surface” includes not only the first to fourth walls 541 to 544 but also the side surface of the bathtub 510. In this example, the wall surface 540 surrounding the washing floor 520 is the side surfaces of the first to third walls 541 to 543 and the bathtub 510. The first to fourth walls 541 to 544 may include bathroom doors and the like.

  In the present specification, the direction from the second wall 542 to the first wall 541 is referred to as “front”, and the opposite direction is referred to as “rear”. Further, a direction perpendicular to the front-rear direction and the up-down direction is defined as a lateral direction.

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

  Counter 530, mirror, faucet and shower hose are attached to second wall 542. The counter 530 includes a counter body and a support member 533 (see FIG. 5). The counter body includes, for example, a top plate 531 and a lower cover 532.

  The counter 530 is disposed to be spaced upward from the washing floor 520. A support member 533 is attached to the second wall 542, and the counter body is attached to the support member. The counter 530 has a substantially rectangular shape that is long in the horizontal direction when viewed from above. The width in the horizontal direction of the counter 530 is equal to the width in the horizontal direction of the washing floor 520.

  The sterilizing water spouting unit 10 is provided below the counter 530. The sterilizing water spouting unit 10 is disposed at a position separated from the washing floor 520. The sterilizing water spouting unit 10 is installed near the center of the counter 530 in the lateral direction, for example. That is, the sterilizing water spouting unit 10 is installed in the vicinity of the center of the washing floor 520 in the lateral direction. Thereby, it becomes easy to discharge the sterilized water to the whole washing place floor 520.

  FIG. 1 illustrates a state in which the vicinity of the counter 530 in which the sterilizing water discharging apparatus 100 is installed is viewed from the side. For example, the sterilizing water spouting unit 10 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 sterilizing water spouting device 100.

  Inside the counter 530 (between the top plate 531 and the lower cover 532), there is a stop cock 53, a solenoid valve 54, a pressure regulating valve 55, a check valve 56, a sterilized water generator 20, and a control. Part 30 is provided. The stop cock 53 is connected to the water supply pipe 51. In the tap water flow path supplied from the water supply pipe, a stop cock 53, an electromagnetic valve 54, a pressure regulating valve 55, a check valve 56, and a sterilized water generator 20 are connected in order from the upstream side.

  In the embodiment, at least a part of the stop cock 53, the electromagnetic valve 54, the pressure regulating valve 55, the check valve 56, the sterilized water generation unit 20, and the control unit 30 is outside the counter 530 or outside the bathroom 500. May be provided. For example, as illustrated in FIG. 2A, the control unit 30 may be provided outside the bathroom 500.

  The tap water supply to the downstream side is controlled by opening and closing the stop cock 53 and the electromagnetic valve 54. The solenoid valve 54 performs an operation of opening the tap water channel or an operation of closing the tap water channel.

  The pressure regulating valve 55 controls the pressure of the supplied tap water. Thereby, the flow volume of the tap water supplied to the disinfection water production | generation part 20 can be adjusted. By adjusting the flow rate of tap water supplied to the sterilized water generating unit 20, the flow rate of sterilized water supplied to the sterilized water spouting unit 10 is adjusted. The flow rate may be adjusted using the electromagnetic valve 54.

  The sterilized water generator 20 is an electrolytic cell having an anode and a cathode. The disinfected water production | generation part 20 applies a voltage between an anode and a cathode, and electrolyzes the tap water which flows between an anode and a cathode. Thereby, the sterilized water production | generation part 20 denatures tap water, and produces | generates sterilized water.

  The sterilized water is, for example, water containing hypochlorous acid. Since tap water contains chloride ions, hypochlorous acid is generated by electrolyzing the chloride ions. As a result, the electrolyzed water changes to 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 in the vicinity of the anode. By changing the flow rate in the sterilized water generation unit 20, the concentration of components contained in the sterilized water can be controlled. The sterilized water generation 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 generating unit 20 is supplied to the sterilized water spouting unit 10 and discharged from the sterilized water spouting unit 10 onto the washing floor 520. Thereby, the washing floor 520 can be sterilized.

  The sterilization water spouting unit 10 includes, for example, a motor 17. The motor 17 is, for example, a stepping motor. As will be described later, the direction in which the sterilized water is discharged can be changed by rotating the sterilized water spouting unit 10 by the motor 17.

  The control unit 30 is connected to the electromagnetic valve 54, the sterilized water generating unit 20, and the sterilized water spouting unit 10 (motor 17). The control unit 30 can control the operation of the sterilized water (water discharge method, how to sprinkle) by controlling the operation of the electromagnetic valve 54, the sterilized water generating unit 20, and the sterilized water spouting unit 10. it can.

  For example, the electromagnetic valve 54 opens and closes the tap water flow path based on a signal from the control unit 30. Thereby, the flow volume of the tap water supplied downstream is controlled. Further, the sterilized water generation unit 20 switches the electrolytic cell ON / OFF based on a signal from the control unit 30. The sterilizing water spouting unit 10 changes the rotation angle and the rotation speed based on the signal from the control unit 30. In this way, the control unit 30 determines the concentration of sterilized water, the instantaneous flow rate of discharged sterilized water (flow rate per unit time), the total amount of discharged sterilized water, the discharge direction of the sterilized water, and the like. The water discharge method 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 sterilizing water spouting device 100 can operate the operation of the sterilizing water spouting device by using the operation unit 35.

  The ease of soiling the wash floor 520 and the ease of flowing sanitized water may vary depending on the location of the wash floor 520. Therefore, the control unit 30 changes the method of discharging the sterilized water according to the angle (direction in which the sterilized water is discharged) that the sterilized water discharge unit 10 is rotated. Thereby, optimal water discharge can be performed according to the site | part of a washroom floor. Thereby, the washing floor can be sterilized efficiently with a smaller amount of sterilized water.

  Next, an example of the sterilizing water spouting unit of the present embodiment will be described with reference to FIGS.

  FIG. 3A and FIG. 3B are schematic views illustrating the sterilized water spouting unit of this embodiment. FIG. 3A is a schematic perspective view of the sterilizing water spouting unit 10. FIG. 3B is a schematic cross-sectional view taken along the line A-A ′ shown in FIG.

  As illustrated in FIG. 3A and FIG. 3B, the sterilized water spouting unit 10 includes a first water spout 11, a second water spout 12, and a water storage unit 13.

  The water storage unit 13 has, for example, a cylindrical shape, and can temporarily store the sterilized water supplied from the sterilized water generation unit 20 in the internal space. The first water outlet 11 and the second water outlet 12 are provided on the side surface of the water reservoir 13. The first water outlet 11 is provided above the second water outlet 12.

  A space in which the sterilized water in the water storage unit 13 accumulates communicates with the outside through the first water outlet 11 and the second water outlet 12. Thereby, the 1st spout 11 and the 2nd spout 12 discharge the sanitization water collected in the water storage part 13 on a washing floor. For example, the first water outlet 11 and the second water outlet 12 simultaneously discharge sterilized water. By providing the water reservoir 13, the sterilized water can be temporarily stored and the water discharge pressure can be increased.

  FIG. 4A and FIG. 4B are schematic side views illustrating a state in which sterilized water is discharged from the sterilized water spouting unit of the present embodiment. FIG. 4B shows an enlarged view of the vicinity of the sterilizing water spouting unit 10 of FIG.

  The first water outlet 11 is provided upward from the second water outlet 12. For example, the first water discharge port 11 is upward from the horizontal direction, and the second water discharge port 12 is downward from the horizontal direction. Thereby, the sterilized water discharged from the first water discharge port 11 reaches a region farther from the sterilized 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 covers a range far from the disinfecting water spout unit 10 in the washing floor 520. The second water spout 12 is a water spout for the vicinity serving a range close to the disinfecting water spout unit 10 in the washing floor 520.

  The maximum water discharge distance of the first water discharge port 11 (the longest distance between the position where the sterilized water discharged from the sterilized water spout unit 10 reaches when there is no obstacle and the sterilized water spout unit 10; range) is It is longer than the longest distance between the sterilizing water spouting unit 10 and the wall surface 540.

  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. In the present specification, the “water discharge direction” refers to a direction in which the sterilized water is discharged when viewed from above. When the sterilized water spreads and is discharged in a plurality of directions when viewed from above, the center of the plurality of directions can be set as the “water discharge direction”.

  Since the diameters of the first water outlet 11 and the second water outlet 12 are small, the sterilized water is discharged in the form of a mist (mist), for example. Such mist-like sterilized water tends to stay on the washing floor. By discharging the sterilized water in a highly retentive form, the time for the sterilized water to act on the bacteria on the washing floor can be secured. Thereby, the washing floor can be sterilized with a smaller amount of sterilized water.

  As shown in FIG. 3A, the disinfecting water spouting unit 10 is provided with a groove 11 g along the vertical direction in the vicinity of the first water spouting port 11. The direction in which the sterilizing water is discharged from the first water outlet 11 is controlled by the groove 11g. Similarly, the direction in which the sterilized water is discharged from the second water outlet 12 is controlled by the groove 12 g provided in the vertical direction provided in the vicinity of the second water outlet 12. As a result, as shown in FIG. 4B, the sterilized water spreads from the first water outlet 11 and the second water outlet 12 in the vertical direction and is discharged.

Fig.5 (a) and FIG.5 (b) are the schematic diagrams explaining rotation of the disinfection water discharging part of this embodiment.
FIG. 5A is a schematic plan view of the counter 530 provided with the sterilizing water spouting unit 10 and the washing floor 520 as viewed from above. FIG.5 (b) is the typical top view which expanded and represented the vicinity of the disinfection water discharging part 10 of Fig.5 (a).

  The sterilizing water spouting unit 10 can rotate around the rotation axis 10x. The rotating shaft 10x is an axis extending in the vertical direction. The rotating shaft 10x is located at the approximate center of the sterilizing water spouting unit 10 when viewed from above. The direction in which the rotation shaft 10x extends may be inclined from the complete vertical direction. For example, the vertical component in the direction in which the rotary shaft 10x extends may be larger than the horizontal component in the direction in which the rotary shaft 10x extends.

  The sterilizing water spouting unit 10 can rotate from the rotation origin 10s (rotation start position) to the rotation end position 10e. The discharge direction of 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 sterilization water discharge unit 10 rotates. Disinfecting water is discharged to the whole washing place floor 520 by discharging the disinfecting water while the disinfecting water spouting unit 10 rotates.

  The disinfecting water spouting device 100 according to the present embodiment has a relative position between a position that serves as a reference when the disinfecting water discharging unit 10 rotates (hereinafter referred to as “rotation reference” for convenience of description) and the washing floor 520. Rotation reference defining means 15 for defining a proper arrangement is further provided. For example, the origin 10s can be used as the rotation reference. The rotation reference defining means 15 is a means for defining the rotation reference at a predetermined angle with respect to the washroom floor 520.

  For example, as illustrated in FIG. 5B, the sterilization water spouting device 100 includes a rotation reference unit 10 p and a rotation reference defining unit 534. Further, the sterilizing water spouting unit 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 fixed directly or indirectly with respect to the counter 530. The rotation reference defining part 534 is provided in the counter 530. The rotation reference defining part 534 is attached to the support member 533 of the counter 530, for example. The rotation reference defining portion 534 may be a member different from the counter 530, or may be formed integrally with the counter 530.

  The rotation reference portion 10p is a member whose position is fixed directly or indirectly 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. Thereby, the rotation reference part 10p is fixed relatively to the counter 530.

The protrusion 10q is a member provided on the side surface of the sterilizing water spouting unit 10 and rotates with the rotation of the first water spout 11 and the second water spout 12. When the sterilizing water spouting unit 10 rotates, the protrusion 10q is disposed so as to abut against the rotation reference unit 10p. Thus, the rotation of the sterilizing water spouting unit 10 is regulated by the rotation reference unit 10p and the protrusion 10q. Thereby, the position of the rotation reference part 10p can be used as the rotation reference. 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 formed integrally with the counter 530. In this case, the rotation reference unit 10p also serves as the rotation reference defining unit 534.

For example, when the sterilizing water spouting unit is attached to a counter in a bathroom, the rotation reference of the sterilizing water spouting unit may be shifted from a predetermined position. When changing the method of spraying sterilized water according to the rotation angle of the sterilized water spouting unit, if the rotation reference of the sterilized water spouting unit is shifted, there is a risk that the optimal method of spraying the sterilized water depending on the site may not be possible. . On the other hand, in the embodiment, the rotation reference defining means 15 as described above is provided. By this rotation reference defining means 15, the rotation reference of the sterilizing water spouting unit 10 can be matched with the washing floor 520. For this reason, it can prevent that the disinfection water spouting part 10 is attached to a counter in the state which the rotation reference | standard shifted | deviated from the predetermined position. Thereby, the optimal water discharge according to the site | part of a washroom floor can be performed reliably.

  In general, the counter is mounted in the bathroom so that the horizontal center of the counter coincides with the horizontal center of the short side of the washing 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 sterilizing water spouting unit 10 is defined with respect to the counter 530. Specifically, a rotation reference unit 10p and a rotation reference defining unit 534, which are defined in relative arrangement with the counter 530, are provided. As a result, the relative arrangement of the rotation reference and the washing floor 520 can be defined via the counter 530. Thereby, optimal water discharge can be reliably performed according to each site | part of a washroom floor.

  Even if the position at which the sterilizing water spouting unit 10 is attached to the counter changes depending on the type of the counter, the rotation reference defining unit is included in the counter in consideration of the relationship between the center of the counter and the position at which the sterilizing water spouting unit 10 is attached. If 534 is formed, the rotation reference corresponding to the washroom floor can be defined. Thereby, the optimal water discharge according to each site | part of the washroom floor 520 can be performed also with respect to the various counters from which the attachment position of the disinfection water discharge part 10 differs mutually.

  Next, an example of the operation of the disinfecting water discharging apparatus 100 when disinfecting the washing floor 520 will be described.

FIG. 6 is a flowchart illustrating the operation of the sterilizing water spouting device according to this embodiment.
FIG. 7 is a schematic plan view illustrating the operation of the sterilizing water spouting unit of this embodiment.
FIG. 7 shows the rotation operation of the sterilizing water spouting unit 10 in each step of the sterilizing method using the sterilizing water spouting device 100.
As shown in FIG. 6, first, when the switch of the sterilizing water spouting device 100 is OFF, the electromagnetic valve 54 is closed, and the electrolytic cell (sterilized water generating unit 20) and the motor 17 are OFF. It is.

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

  In the origin search mode S01, the control unit 30 performs the origin of rotation of the sterilizing water spouting unit 10 using the rotation reference defining means 15. Here, the “origin search” refers to an operation in which the position (orientation) of the sterilizing water spouting unit 10 is made to correspond to the rotation reference. Specifically, the control unit 30 turns on the motor 17 (operating state) and rotates the sterilized water spouting unit 10 in the direction represented by the arrow A01 in FIG.

FIG. 8A and FIG. 8B are schematic plan views for explaining origin search in the present embodiment. FIG. 8A and FIG. 8B show the operation of the sterilizing water spouting unit 10.
As shown in FIG. 8A, the angle from the origin 10s to the end position 10e (maximum rotation angle θ1) is, for example, about 300 °. In the origin search mode S01, the control unit 30 sends a signal to the motor 17 so as to rotate the maximum rotation angle θ1.

As shown in FIG. 8B, for example, when the switch of the sterilizing water spouting device 100 is turned ON, the angle at which the sterilizing water spouting unit 10 is rotated from the origin 10s is θ2. At this time, the sterilizing water spouting unit 10 first rotates by the angle θ2. Thereby, the protrusion part 10q of the disinfection water discharging part 10 hits the rotation reference | standard part 10p. Further, in this state, the motor 17 idles by the difference (angle θ3) between the maximum rotation angle θ1 and the angle θ2. Thereby, the direction of the sterilization water spouting part 10 is reliably adjusted to the origin 10s (rotation reference).

  Next, the control part 30 performs 1st disinfection water discharging process S02. In the first sterilizing water spouting step S02, the electromagnetic valve 54 is opened, and tap water is supplied to the electrolytic cell. The electrolytic cell is turned on to denature tap water and generate sterilized water. The produced sterilized water is discharged from the sterilized water spouting unit 10 to the washing floor 520. At this time, the control unit 30 turns on the motor 17 and rotates the sterilizing water spouting unit 10 from the origin 10s to the end position 10e as shown by an arrow A02 in FIG. The sterilizing water spouting unit 10 discharges the sterilizing water onto the washing floor 520 while rotating.

  In addition, in each arrow represented in FIG. 7, when the sterilizing water spouting unit 10 rotates in the direction represented by the broken line, it indicates that the sterilizing water spouting unit 10 does not discharge the sterilizing water. Moreover, when the sterilizing water spouting unit 10 rotates in the direction represented by the solid line, it indicates that the sterilizing water spouting unit 10 discharges the sterilizing water.

  Next, the water stop process S03 is performed. In the water stop process S03, the electromagnetic valve 54 is closed and the electrolytic cell is turned off (stopped state). The motor 17 is also turned off (stopped).

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

  Then, the control part 30 performs 2nd disinfection water discharging process S05. In the second sterilizing water discharging process S05, the electromagnetic valve 54 is opened and the electrolytic cell is turned on. The control unit 30 rotates the sterilized water spouting unit 10 by the motor 17. The sterilizing water spouting unit 10 discharges sterilizing water while rotating from the origin 10s to the end position 10e as shown by an arrow A05 in FIG. The discharging method of the disinfecting water in the second disinfecting water discharging step S05 may be different from the first disinfecting water discharging step S02. For example, the component and concentration of the sterilizing water discharged in the second sterilizing water discharging step S05 may be different from the component and the concentration of sterilizing water discharged in the first sterilizing water discharging step S02.

  Next, the sterilization water spouting completion step S06 is performed. In the sterilization water spouting completion step S06, the electromagnetic valve 54 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 passage of the sterilized water in the sterilized water spouting unit 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 sterilizing water spouting unit 10. The sterilizing water spouting unit 10 rotates from the end position 10e to the origin 10s as shown by an arrow A07 in FIG. 7 while vibrating.

  For example, when the sterilizing water spouting device 100 is not used, the user's body may hit the sterilizing water spouting unit 10 and the angle of the sterilizing water spouting unit 10 with respect to the washing floor 520 may be shifted. Even in such a case, according to the embodiment, since the origin is performed before the washing place sterilization mode, the discharge of the sterilized water is started with the angle deviation corrected. Thereby, optimal water discharge can be performed according to the site | part of a washroom floor stably for a long term.

  In addition, when the sterilizing water spouting device is used for a long period of time, the movement resistance (resistance during rotation) of the sterilizing water spouting unit 10 increases, and the washing place of the sterilizing water spouting part 10 is executed during the execution of the washing place sterilization mode. The angle with respect to the floor 520 may deviate from the intended angle. In addition, when an obstacle is placed around the sterilizing water spouting unit 10, the sterilizing water spouting unit 10 may hit the obstacle when the sterilizing water spouting unit 10 rotates. Also at this time, the angle of the sterilizing water spouting unit 10 with respect to the washing floor 520 may deviate from the intended angle.

  On the other hand, in the embodiment, the origin search mode S04 is executed between the first sterilization water discharge process S02 and the second sterilization water discharge process S05. That is, the control unit 30 executes the origin search mode in the middle of the washing place sterilization mode. Thereby, the shift | offset | difference of the angle with respect to the washing place floor 520 of the sterilization water spouting part 10 can be corrected in the middle of the washing place sterilization mode. For this reason, it is possible to prevent the sterilized water from being discharged in a state in which the angle of the sterilized water spouting unit 10 with respect to the washing floor 520 is greatly deviated. Thereby, optimal water discharge can be performed according to the site | part of the washroom floor 520 stably for a long period of time.

  Next, operation | movement of the sterilization water discharging apparatus in 1st sterilization water discharging process S02 is further demonstrated with reference to FIGS.

FIG. 9 is a time chart for explaining the operation of the sterilizing water spouting device in the present embodiment.
In FIG. 9, operation | movement in 1st disinfection water discharging process S02 and origin search mode S04 is shown.
As shown in FIG. 9, in the first sterilizing water spouting step S <b> 02, the sterilizing water continues to be discharged from the sterilizing water spouting unit 10. And in origin search mode S04 of water stop process S03, disinfection water is not discharged from the disinfection water spouting part 10.

In the “rotation of the sterilizing water spouting unit” in the time chart, “1” represents that the sterilizing water spouting unit 10 is rotating from the origin 10 s toward the end position 10 e (forward rotation operation). “Represents that the sterilizing water spouting unit 10 has stopped rotating, and“ −1 ”represents that the sterilizing water spouting unit 10 is rotating from the end position 10 e toward the origin 10 s (inversion operation). ).
As shown in FIG. 9, the sterilizing water spouting unit 10 repeats rotation and stop. In the first sterilizing water spouting step S02, the sterilizing water spouting unit 10 intermittently rotates in a direction from the origin 10s to the end position 10e. In the origin search mode S04, the sterilizing water spouting unit 10 intermittently rotates in a direction from the end position 10e toward the origin 10s.

FIG. 10 is a schematic plan view illustrating the operation of the sterilizing water spouting unit of this embodiment.
A region A1 represents a region where the sterilized water is discharged during a certain period t1 when the sterilized water spouting unit 10 stops rotating. A region A2 represents a region where the sterilized water is discharged in the period t2 in which the sterilized water spouting unit 10 stops rotating after the period t1. As shown in FIG. 10, a part of the area A2 overlaps with a part of the area A1. Thus, the sterilizing water spouting unit 10 intermittently rotates from the origin 10s to the end position 10e.

  Furthermore, in this embodiment, the sterilizing water spouting device 100 changes the amount of sterilizing water discharged and the rotation speed of the sterilizing water spouting unit 10 according to the site of the washing floor 520. This will be described below.

Fig.11 (a) and FIG.11 (b) are typical top views explaining operation | movement of the disinfection water discharging part of this embodiment.
FIG. 11A is a schematic plan view illustrating the sterilizing water spouting unit 10, and FIG. 11B is a schematic plan view illustrating the washing floor 520.

  As shown in FIG. 11A, in this example, the angle (rotation angle) that the sterilizing water spouting unit 10 rotates is divided into five different ranges D1 to D5. FIG.11 (b) represents area | region R1-R5 of the washing floor 520 corresponding to each of the ranges D1-D5.

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

  The distance from the sterilized water spouting unit 10 to the wall surface 540 along the water discharging direction in the state ST1 is shorter than the distance from the sterilizing water spouting unit 10 to the wall surface 540 along the water discharging direction in the state ST2. At this time, as shown in FIG. 9, 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 where the rotation angle is within the range D3, the sterilized water is discharged to the region R3. The distance from the sterilized water spouting unit 10 to the wall surface 540 along the water discharging direction in the state ST3 is longer than the distance from the sterilizing water spouting unit 10 to the wall surface 540 along the water discharging direction 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.

  Thus, in the embodiment, the total amount of the sterilizing water discharged in the rotation angle region where the distance between the sterilizing water spouting unit 10 and the wall surface 540 is relatively short is the sterilizing water spouting unit 10 and the wall surface. The total distance between the 540 and the 540 is less than the total amount of sterilized water discharged in a relatively long rotation angle region.

  In the state ST4 where the rotation angle is within the range D4, the sterilized water is discharged to the region R4. The distance from the sterilized water spouting unit 10 to the wall surface 540 along the water discharging direction in the state ST4 is the same as the distance from the sterilizing water spouting unit 10 to the wall surface 540 along the water discharging direction in the state ST2. In addition, 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 washing 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 sterilizing water spouting unit 10 and the wall surface 540 is the same, the amount of the sterilizing water discharged to the downstream side of the drainage gradient of the washing floor 520 is the drainage gradient of the washing floor 520. Less than the amount of sterilized water discharged upstream.

  For example, the instantaneous flow rate of the sterilized water discharged from the sterilized water spouting unit 10 is constant. And the control part 30 changes the average rotational speed of the sterilization water spouting part 10 according to the distance from the sterilization water spouting part 10 to the wall surface 540 along the water discharging direction. Thereby, according to the site | part of a washroom floor, the total amount of the disinfecting water discharged can be changed. For example, the average rotational speed of the sterilized water spouting unit 10 in the state ST1 is higher than the average rotational speed of the sterilizing water spouting unit 10 in the state ST3. Thereby, the total amount of the sterilized water discharged in the state ST1 is smaller than the total amount of the sterilized water discharged in the state ST3.

  As shown in FIG. 9, when the sterilizing water spouting unit 10 repeats rotation and stop, the average rotational speed can be changed by changing the length of time during which the sterilizing water spouting unit 10 stops. it can. For example, it is possible to change the average rotation speed by changing the temporal cycle in which the rotation operation is performed while keeping the angle and time at which the sterilizing water spouting unit 10 rotates at a time constant. For example, the cycle of the rotation operation in the state ST1 is shorter than the cycle of the rotation operation in the state ST3.

  In the time chart, the “water discharge state” represents a direction in which the sterilized water is discharged in each range of the rotation angle in a schematic plan view. Moreover, the arrow in a top view represents the flow of the disinfecting water which flows on the washing floor 520 after hitting the wall surface 540 out of the disinfecting water discharged from the disinfecting water spouting unit 10. The direction of the arrow schematically represents the direction in which the sterilized water flows, and the size of the arrow schematically represents the amount of the sterilized water. In the time chart, “floor surface state” represents the amount of sterilized water present on the washing floor 520 in each state in gray scale. This gray scale indicates that the darker the color (closer to black), the greater the amount of sterilized water.

As already described, the maximum water discharge distance from which the sterilizing water spouting unit 10 discharges the sterilizing water is longer than the maximum distance between the sterilizing water spouting unit 10 and the wall surface 540. By rotating the sterilizing water spouting unit 10 as described above, it becomes possible to discharge the sterilizing water to the entire washing floor 520, and the entire washing floor can be sterilized.

  However, when the sterilizing water spouting unit 10 is rotated, the distance between the sterilizing water spouting unit 10 and the wall surface 540 along the water discharging direction changes. In such a state, when water discharge is performed in the same direction in all directions, sterilization is performed on the washing floor 520 due to a change in the distance between the sterilized water discharge unit 10 and the wall surface 540 along the water discharge direction. A region where water is excessively discharged is generated. For this reason, a large amount of sterilized water is required.

  On the other hand, not only the sterilized water directly reaching the washing ground floor 520 from the sterilizing water spouting unit 10 but also the sterilizing water flowing on the washing ground floor 520 after hitting the wall surface 540 has a sterilizing effect. Therefore, by sterilizing using the sterilized water flowing on the wall surface 540, the entire washing floor 520 can be sterilized with a small amount of sterilized water.

  For example, when the distance between the sterilizing water spouting unit 10 and the wall surface 540 along the water discharging direction is short as in the state ST1, the washing floor 520 is discharged from the sterilizing water spouting unit 10 and hits the wall surface 540. There is a relatively large amount of sanitized water flowing upward. For this reason, 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 sterilized water discharged in the state ST1 is reduced, the sterilization effect can be obtained.

  Therefore, according to the embodiment, when the distance from the sterilizing water spouting unit 10 to the wall surface 540 along the discharge direction of the sterilizing water is short, it is possible to prevent unnecessary sterilizing water from being discharged. . Thereby, the total amount of the sterilized water discharged to the whole washing place floor 520 can be reduced.

  Furthermore, in the embodiment, when the distance from the sterilizing water spouting unit 10 to the wall surface 540 along the water discharging direction of the sterilizing water is the same, the amount of the sterilizing water discharged upstream of the washing floor 520 is The amount is less than the amount of sterilized water discharged to the downstream side of the floor 520. The sterilized water discharged to the upstream side of the washing floor 520 flows to the downstream side of the washing floor 520. For this reason, it is possible to sterilize the downstream side of the washing floor 520 using the sterilizing water discharged to the upstream side of the washing floor 520. Thereby, even if the amount of the sterilizing water discharged to the downstream side of the washing ground floor 520 is reduced, the entire washing ground floor 520 can be sterilized.

Moreover, when changing the quantity of the disinfecting water discharged according to the site | part on the washing floor 520, the method of changing the instantaneous flow volume of disinfecting water can be considered. The instantaneous flow rate of the sterilized water discharged from the sterilized water spouting unit 10 depends on the instantaneous flow rate in the sterilized water generating unit 20. However, when the instantaneous flow rate in the sterilized water generating unit 20 is changed, the concentration of the sterilized water component generated in the sterilized water generating unit 20 changes. On the other hand, in the embodiment, the average rotational speed of the sterilized water spouting unit 10 is changed with the instantaneous flow rate of the sterilized water constant. Thereby, the density | concentration of sanitization water can be made into a fixed state, and the total amount of sanitization water discharged to the predetermined range of the washing floor 520 can be changed.

  When the average rotation speed of the sterilizing water spouting unit 10 is changed, if the rotation speed is increased too much, the torque may be insufficient and a malfunction may occur. On the other hand, in the embodiment, the control unit 30 switches between a state in which the sterilizing water spouting unit 10 processes and a state in which the sterilizing water spouting unit 10 stops rotating. And the average rotational speed is changed by changing the length of time for which the sterilizing water spouting unit 10 stops rotating. Thereby, problems such as insufficient torque can be prevented.

  Next, operation | movement of the disinfecting water discharging apparatus 100 in residual water discharge mode S07 is further demonstrated with reference to FIG. 12 and FIG.

  FIG. 12 is a flowchart illustrating the operation of the sterilizing water spouting device in the present embodiment. FIG. 13 is a time chart for explaining the operation of the sterilizing water spouting device in the present embodiment.

  As shown in FIG. 12 and FIG. 13, the residual water discharge mode S07 includes a first vibration step S17 and a second vibration step S27 executed after the first vibration step S17.

  As shown in FIG. 13, in the first vibration step S <b> 17, the sterilizing water spouting unit 10 repeats rotation and stop. The sterilizing water spouting unit 10 intermittently rotates from the end position 10e to the origin 10s. Thereby, the sterilization water spouting part 10 vibrates. By this vibration, the surface tension of the sterilized water remaining in the sterilized water spouting unit 10 can be reduced (destroyed). Thereby, the sterilized water remaining in the flow path in the sterilized water spouting unit 10 is discharged.

  Such residual water discharge mode S07 is executed immediately after the washing place sterilization mode (second sterilization water discharge 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. For this reason, the sterilized water discharged in the residual water discharge mode S07 falls on the water film.

  When the amount of sterilized water discharged on the washing floor 520 is small, the sterilized water becomes polka-dot residual water and hardly flows to the drain outlet. On the other hand, when the sanitized water is in the form of a film, the sanitized water tends to flow to the drain outlet along the drainage gradient of the washing floor 520.

  In the embodiment, the sterilized water discharged from the sterilized water discharge unit is dropped on the water film. Thereby, the disinfecting water discharged from the disinfecting water spouting part can be flowed to the drain outlet together with the disinfecting water forming the water film. Therefore, even when the diameter of the spout is reduced in order to discharge the sterilized water in a highly retentive form, the residual water is washed after a long time has elapsed since the end of the operation of the sterilized water spouter. Occurrence on the floor can be prevented.

  Further, in the first vibration step S17, the sterilizing water spouting unit 10 is rotated from the end position 10e to the origin 10s. That is, the sterilizing water spouting unit 10 is vibrated while changing the position where the sterilizing water remaining in the sterilizing water spouting unit 10 falls. Thereby, the plane area of the area | region where disinfection water falls on the washing-room floor 520 can be enlarged. For this reason, the possibility that the sterilized water dropped from the sterilized water spouting unit 10 and the membrane-shaped sterilized water on the washing floor 520 may be increased. Thereby, the sterilized water discharged from the sterilized water spouting unit 10 can be more reliably guided to the drain outlet together with the sterilized water forming the water film.

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

  Due to the difference in vibration, the sterilized water that could not be discharged in the first vibration step S17 can be discharged in the second vibration step S27. Thereby, the quantity of the disinfecting water remaining in the disinfecting water spouting unit 10 can be further reduced.

  For example, in the second vibration step S27, the control unit 30 moves the positions of the water discharge ports (the first water discharge port 11 and the second water discharge port 12) in a plurality of directions. That is, as shown in FIG. 13, the forward rotation operation and the reverse operation are alternately repeated.

  In the second vibration step, the forward rotation operation and the reversal operation are repeated after the protrusion 10q hits the rotation reference portion 10p. For this reason, in the 2nd vibration process, the range which a spout moves is narrower than the range which a spout moves in a 1st vibration process. Each time the forward rotation operation and the reverse operation are repeated, the protrusion 10q comes into contact with the rotation reference portion 10p. For this reason, in the 2nd vibration process, a stronger shake than a 1st vibration process arises in a water outlet. Thereby, the quantity of the disinfecting water remaining in the disinfecting water discharge part can be further reduced.

Next, another embodiment of the present invention will be described with reference to the drawings.
FIG. 14A and FIG. 14B are schematic plan views illustrating a sterilizing water spouting device according to another embodiment of the present invention. FIG. 14A is a schematic plan view of the counter 530a provided with the sterilizing water spouting unit 10 and the washing ground floor 520 as viewed from above. FIG. 14B is a schematic plan view showing the vicinity of the sterilizing water spouting unit 10 of FIG.

  In this example, the shape of the counter 530a provided with the sterilizing water discharge unit 10 is different from the shape of the counter 530 described above. Accordingly, the relative arrangement of the washing floor 520 and the sterilized water spouting unit 10 is different from the example illustrated in FIG. 5, for example.

  A rotation reference defining portion 534 that is the rotation reference defining means 15 is attached to a support member 533 located at the end of the counter 530a in the lateral direction. For this reason, the sterilizing water spouting unit 10 is located not at the center in the lateral direction of the counter 530a but at the end.

  That is, in this example, the sterilizing water spouting unit 10 is provided not at the center in the lateral direction of the washing floor 520 but at the end of the washing floor 520 in the lateral direction. Other than this, the sterilizing water spouting device shown in FIG. 14 is the same as the sterilizing water spouting device 100 described in FIGS.

  As described above, even if the position where the sterilizing water spouting unit 10 is attached to the counter changes in this way, the relationship between the center of the counter and the position where the sterilizing water spouting unit 10 is attached is taken into account. If the rotation reference defining part 534 is formed, a rotation reference corresponding to the washing floor can be defined. Thereby, the optimal water discharge according to each site | part of the washing-room floor 520 can be performed.

  Even in this case, as shown in FIG. 14A, the average rotation speed of the sterilizing water spouting unit 10 is changed according to the distance from the sterilizing water spouting unit 10 to the wall surface 540 along the water discharging direction. Thereby, according to the site | part of the washing floor 520, the total amount of the disinfecting water discharged can be changed. Thus, the optimal water discharge according to each site | part of the washing-room floor 520 can be performed.
