Description

  Embodiments of the present invention generally relate to a sanitizing water spouting device for a bathroom washroom.

  For example, dirt such as soap and shampoo used for washing the human body and reds (proteins, carbohydrates, oils and fats, salts, etc.) generated from the human body adhere to the floor of the bathroom. A cleaning device for removing bacteria caused by such dirt has been proposed.

  In the cleaning device disclosed in Patent Literature 1, a water discharging section that can discharge water is provided below a bathroom counter. In such a washing apparatus, the disinfecting water is discharged onto the washing floor while rotating the spouting section. Thereby, the whole washing floor can be disinfected.

However, when the disinfecting water spouting section is rotated, the distance between the disinfecting water spouting section and the wall surface along the water spouting direction changes. In such a state, if water is discharged in all directions in the same manner, due to a change in the distance between the disinfecting water spouting section and the wall surface along the water discharging direction, the disinfecting water becomes excessive on the washing floor. A region to be ejected is generated. For this reason, a large amount of sterilized water is required.

FIG. 1 is a schematic view illustrating a disinfecting water spouting device for a bathroom washing place according to an embodiment of the present invention.
As shown in FIG. 1, a sanitizing water spouting device (hereinafter, simply referred to as a “sanitizing water spouting device”) 100 for a bathroom washroom according to an embodiment of the present invention includes a sanitizing water spouting unit. 10, a sterilized water generator 20, and a controller 30. The disinfecting water spouting device 100 is a device that is installed in a bathroom and disinfects a washing floor of the bathroom.

First, an example of a bathroom in which the disinfecting water spouting device 100 is installed will be described.
FIG. 2A and FIG. 2B are schematic perspective views showing a bathroom in which the sanitizing water discharge device for a bathroom washing place according to the present embodiment is installed.
As shown in FIG. 2A, the bathroom 500 in which the disinfecting water spouting device 100 is installed has a first
To a fourth wall 541 to 544, a bathtub 510, a washing floor 520 and a counter 530 are provided. Further, the bathroom 500 is provided with a mirror, a water tap, a shower hose, and the like as appropriate. FIG. 2B is a schematic perspective view in which the vicinity of the counter 530 is enlarged.

  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 as viewed from the washing floor 520. For example, bathtub 510 is arranged so as to be in contact with fourth wall 544.

  Washing floor 520 is provided between bathtub 510 and third wall 543. For example, the washing floor 520 is in contact with the first to third walls 541 to 543.

  The washing floor 520 is surrounded by a wall 540 erected on 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 a side surface of the first to third walls 541 to 543 and the bathtub 510. The first to fourth walls 541 to 544 may include a bathroom door or 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”. The direction perpendicular to the front-rear direction and the up-down direction is defined as the horizontal direction.

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

  The counter 530, mirror, hydrant and shower hose are mounted on the second wall 542. The counter 530 has a counter main body and a support member 533 (see FIG. 5). The counter body has, for example, a top plate 531 and a lower cover 532.

  The counter 530 is arranged to be spaced upward from the washing floor 520. 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 washing floor 520 in the horizontal direction.

The disinfecting water spouting section 10 is provided below the counter 530. The disinfecting water spouting section 10 is arranged at a position separated from the washing floor 520. The sanitizing water spouting section 10 is installed, for example, near the center of the counter 530 in the horizontal direction. That is, the disinfecting water spouting section 10 is installed near the center in the horizontal direction of the washing floor 520. This makes it easier to discharge the sterilizing water to the entire washing floor 520.

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

  Outside the bathroom 500 (for example, behind the second wall 542), a water supply pipe 51 and a hot water supply pipe 52 are provided. 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), the stopcock 53, the solenoid valve 54, the pressure regulating valve 55, the check valve 56, the sterilizing water generator 20 and the control And a unit 30 are provided. The water stopcock 53 is connected to the water supply pipe 51. In the flow path of the tap water supplied from the water supply pipe, the stopcock 53, the solenoid valve 54, the pressure regulating valve 55, the check valve 56, and the sterilization water generator 20 are connected in order from the upstream side.

  In the embodiment, at least a part of the stopcock 53, the solenoid valve 54, the pressure regulating valve 55, the check valve 56, the sterilized water generation unit 20 and the control unit 30 is provided outside the counter 530 or outside the bathroom 500. May be provided. 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 stopcock 53 and the solenoid valve 54. The solenoid valve 54 performs an operation of opening a flow path of tap water or an operation of closing a flow path of tap water.

  The pressure regulating valve 55 controls the pressure of the supplied tap water. Thereby, the flow rate of the tap water supplied to the sterilized water generator 20 can be adjusted. By adjusting the flow rate of the tap water supplied to the sterilized water generation unit 20, the flow rate of the sterilized water supplied to the sterilized water spouting unit 10 is adjusted. Note that 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 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 generator 20 denatures the tap water to generate sterilized water.

  The sanitized 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, in the vicinity of the cathode, alkaline water is generated. 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 generator 20, the concentration of the components contained in the sterilized water can be controlled. It should be noted that the disinfecting water generator 20 is not limited to the electrolytic cell. For example, the disinfecting water may be disinfecting water generated by dissolving a disinfectant in tap water.

  The disinfecting water generated in the disinfecting water generating unit 20 is supplied to the disinfecting water spouting unit 10 and discharged from the disinfecting water spouting unit 10 onto the washing floor 520. Thereby, the washing floor 520 can be sterilized.

  The sanitizing water spouting section 10 has, for example, a motor 17. The motor 17 is, for example, a stepping motor. As will be described later, the disinfecting water spouting section 10 can be rotated by the motor 17 to change the direction in which the disinfecting water is discharged.

  The control unit 30 is connected to the electromagnetic valve 54, the sterilized water generation unit 20, and the sterilized water spouting unit 10 (motor 17). The control unit 30 controls the operation of the solenoid valve 54, the sterilized water generation unit 20, and the sterilized water spouting unit 10 to control the form (water spouting method, spraying method) of the sterilized water. it can.

  For example, the solenoid valve 54 opens and closes the flow path of tap water based on a signal from the control unit 30. Thereby, the flow rate of the tap water supplied to the downstream side is controlled. Further, the sterilized water generator 20 switches ON / OFF of the electrolytic cell based on a signal from the controller 30. The disinfecting water spouting section 10 changes the rotation angle and the rotation speed based on the signal from the control section 30. In this manner, the control unit 30 can control the concentration of the sterilized water, the instantaneous flow rate (the flow rate per unit time) of the sterilized water to be discharged, the total amount of the sterilized water to be discharged, and the discharge direction of the sterilized water. Can control the water discharge method.

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

  The ease with which the washing floor 520 is contaminated and the ease with which sterilized water flows can vary depending on the location of the washing floor 520. Therefore, the control unit 30 changes the method of discharging the sterilized water according to the angle at which the sterilized water discharging unit 10 rotates (the direction in which the sterilized water is discharged). Thereby, optimal water discharge can be performed according to the site of the washing floor. Thereby, the floor of the washing place can be efficiently disinfected with a smaller amount of disinfecting water.

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

  FIG. 3A and FIG. 3B are schematic diagrams illustrating a disinfecting water spouting unit of the present embodiment. FIG. 3A is a schematic perspective view of the disinfecting water spouting section 10. FIG. 3B is a schematic cross-sectional view taken along the line A-A ′ shown in FIG.

  As shown in FIG. 3A and FIG. 3B, the sanitized water spouting section 10 has a first spout 11, a second spout 12, and a water storage section 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 an internal space. The first water outlet 11 and the second water outlet 12 are provided on a side surface of the water storage unit 13. The first water outlet 11 is provided above the second water outlet 12.

  The space in the reservoir 13 where the sterilized water is stored communicates with the outside via the first water outlet 11 and the second water outlet 12. Thus, the first water outlet 11 and the second water outlet 12 discharge the sterilized water stored in the water storage unit 13 onto the washing floor. For example, the first water outlet 11 and the second water outlet 12 simultaneously discharge sterilized water. By providing the water storage section 13, the sterilized water can be temporarily stored, and the water discharge pressure can be increased.

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

  The first water outlet 11 is provided above the second water outlet 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 outlet 11 reaches a region farther from the sterilized water discharge part 10 than the sterilized water discharged from the second water outlet 12. The first water outlet 11 is a remote water outlet that covers a range of the washing floor 520 that is far from the sanitized water outlet 10. The second water outlet 12 is a nearby water outlet that covers a range close to the sanitizing water outlet 10 in the washing floor 520.

  The maximum water discharge distance of the first water discharge port 11 (the longest distance between the position at which the sterilized water discharged from the sterilized water discharge section 10 when there is no obstacle and the sterilized water discharge section 10; range) is It is longer than the longest distance between the disinfecting water spouting section 10 and the wall surface 540.

  Further, in this example, the direction in which the disinfecting water is discharged from the second water outlet 12 is a direction along the direction in which the disinfecting 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 outlet 11 is substantially the same as the water discharge direction of the second water outlet 12. In the specification of the present application, the “water discharge direction” refers to the direction in which the sterilized water is discharged when viewed from above. In the case where the disinfecting water is discharged in a plurality of directions when discharged 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, for example, in the form of a mist. Such a mist of disinfecting water tends to stay on the washing floor. By discharging the disinfecting water in a form having a high stagnation property, it is possible to secure time for the disinfecting water to act on the bacteria on the washing floor. As a result, the washing floor can be disinfected with a smaller amount of disinfecting water.

  As shown in FIG. 3A, the sterilized water spouting section 10 is provided with a groove 11 g extending in the vertical direction in the vicinity of the first spout 11. The direction in which the sterilized 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 vertical groove 12g provided near the second water outlet 12. As a result, as shown in FIG. 4B, the sterilized water is discharged from the first water outlet 11 and the second water outlet 12 while spreading in the vertical direction.

FIGS. 5A and 5B are schematic diagrams illustrating rotation of the sterilizing water spouting section of the present embodiment.
FIG. 5A is a schematic plan view of the counter 530 provided with the disinfecting water spouting section 10 and the washing floor 520 as viewed from above. FIG. 5B is an enlarged schematic plan view showing the vicinity of the disinfecting water spouting section 10 in FIG. 5A.

  The disinfecting water spouting section 10 can rotate around a rotation axis 10x. The rotation axis 10x is an axis extending in the vertical direction. The rotation shaft 10x is located substantially at the center of the sterilized water spouting section 10 when viewed from above. The direction in which the rotation axis 10x extends may be inclined from a completely vertical direction. For example, the vertical component in the direction in which the rotation axis 10x extends may be larger than the horizontal component in the direction in which the rotation axis 10x extends.

  The disinfecting water spouting section 10 can rotate from the rotation origin 10s (the rotation start position) to the rotation end position 10e. The spouting direction of the sterilized water discharged from the first spout 11 and the second spout 12 changes depending on the angle at which the sterilized water spouting section 10 rotates. By discharging the disinfecting water while the disinfecting water spouting section 10 rotates, the disinfecting water is discharged to the entire washing floor 520.

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

  For example, as shown in FIG. 5B, the sterilizing water spouting device 100 is provided with a rotation reference portion 10 p and a rotation reference defining portion 534. Further, the disinfecting water spouting section 10 is provided with a projection 10q. As the rotation reference defining unit 15, a rotation reference unit 10p and a rotation reference defining unit 534 can be used.

  The rotation reference defining unit 534 is a member whose position is fixed directly or indirectly with respect to the counter 530. The rotation reference defining unit 534 is provided in the counter 530. The rotation reference defining unit 534 is attached to, for example, the support member 533 of the counter 530. The rotation reference defining unit 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 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 relatively to the counter 530.

The protrusion 10q is a member provided on the side surface of the sterilized water spouting section 10, and rotates with the rotation of the first spout 11 and the second spout 12. When the disinfecting water spouting section 10 rotates, the projection 10q is arranged so as to abut the rotation reference section 10p. In this manner, the rotation of the sterilizing water spouting section 10 is regulated by the rotation reference section 10p and the projection section 10q. Thereby, the position of the rotation reference portion 10p can be used as the rotation reference. Then, the relative arrangement between the rotation reference and the counter 530 is specified by the rotation reference specifying unit 534.
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 specifying unit 534.

  For example, when attaching the disinfecting water spout to the counter in the bathroom, the rotation reference of the disinfecting water spout may deviate from a predetermined position. When changing the method of disinfecting water according to the rotation angle of the disinfecting water spouting unit, if the rotation reference of the disinfecting water spouting unit is shifted, there is a possibility that the optimal disinfecting water spraying method according to the site may not be possible . On the other hand, in the embodiment, the rotation reference defining means 15 as described above is provided. The rotation reference defining means 15 can adjust the rotation reference of the sterilizing water spouting section 10 to the washing floor 520. Therefore, it is possible to prevent the disinfecting water spouting section 10 from being attached to the counter with the rotation reference deviated from the predetermined position. Thereby, it is possible to surely perform the optimal water discharge according to the portion of the washing floor.

  Generally, the counter is mounted in the bathroom such that the lateral center of the counter coincides with the lateral center of the short side of the wash floor. That is, the relative arrangement between the counter and the washroom floor is predetermined. Therefore, in the present embodiment, the position of the disinfecting water spouting section 10 is defined with respect to the counter 530. Specifically, a rotation reference unit 10p and a rotation reference specifying unit 534 in which the relative arrangement with respect to the counter 530 is specified are provided. Thus, the relative arrangement between the rotation reference and the washing floor 520 can be defined via the counter 530. This makes it possible to reliably perform optimal water discharge according to each part of the washing floor.

  Even if the position at which the disinfecting water spouting section 10 is attached to the counter changes depending on the type of the counter, the counter is attached to the counter in consideration of the relationship between the center of the counter and the position at which the sanitizing water spouting section 10 is attached. If 534 is formed, a rotation reference corresponding to the washing floor can be defined. Thereby, it is possible to perform optimal water discharge according to each part of the washing floor 520 even for various types of counters in which the disinfecting water discharge part 10 is attached at different positions.

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

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

  Here, for example, when the switch of the sterilizing water spouting device 100 is turned ON by the user, an execution instruction of the washing area sanitizing mode (a sterilizing water spouting step 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 search for the origin of the rotation of the sterilized water spouting unit 10 using the rotation reference defining unit 15. Here, "originating" refers to an operation in which the position (orientation) of the disinfecting water spouting section 10 corresponds to the rotation reference. Specifically, the control unit 30 turns on the motor 17 (operating state), and rotates the disinfecting water spouting unit 10 in a direction indicated by an arrow A01 in FIG.

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

  As shown in FIG. 8B, for example, it is assumed that when the switch of the sanitized water spouting device 100 is turned ON, the angle at which the sterilized water spouting section 10 rotates from the origin 10 s is θ2. At this time, the disinfecting water spouting section 10 first rotates by the angle θ2. As a result, the projection 10q of the sterilizing water spouting section 10 abuts on the rotation reference section 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 disinfecting water spouting section 10 is surely adjusted to the origin 10 s (rotation reference).

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

  In addition, in each arrow shown in FIG. 7, when the sanitized water spouting section 10 rotates in the direction indicated by the broken line, it indicates that the sanitized water spouting section 10 does not discharge the sterilized water. When the sanitized water spouting section 10 rotates in the direction indicated by the solid line, it indicates that the sanitized water spouting section 10 discharges the sterilized water.

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

  Next, the control unit 30 executes an origin search mode S04. In the origin search mode S04, the control unit 30 performs the origin search of the sterilizing 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 indicated by an arrow A04 in FIG. At this time, the sterilized water spouting section 10 does not discharge the sterilized water.

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

  Next, a sterilization water discharge completion step S06 is executed. In the sterilization water discharge 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 flow of the sterilized water in the sterilized water spouting section 10 is discharged. For example, the sterilized water remaining in the flow path from the water storage section 13 to the first water outlet 11 or the flow path from the water storage section 13 to the second water outlet 12 is discharged. Specifically, the control unit 30 controls the motor 17 to vibrate the disinfecting water spouting unit 10. The disinfecting water spouting section 10 rotates from the end position 10e to the origin 10s while vibrating, as indicated by an arrow A07 in FIG.

  For example, when the disinfecting water spouting device 100 is not used, the angle of the disinfecting water spouting portion 10 with respect to the washing floor 520 may be shifted due to the user's body hitting the disinfecting water spouting portion 10 or the like. Even in such a case, according to the embodiment, since the origin is set before the washing germ removal mode, the discharge of the germicidal water is started in a state where the angle deviation is corrected. This makes it possible to stably perform optimal water discharge according to the site of the washing floor on a long-term basis.

  In addition, if the disinfecting water spouting device is used for a long period of time, the movement resistance (rotational resistance) of the disinfecting water spouting unit 10 increases, and during the execution of the washing disinfection mode, the washing water of the disinfecting water spouting unit 10 is increased. The angle with respect to the floor 520 may deviate from the intended angle. Further, when an obstacle is placed around the sanitized water spouting section 10, when the sanitized water spouting section 10 rotates, the sanitized water spouting section 10 may hit the obstacle. Also at this time, the angle of the disinfecting water spouting section 10 with respect to the washing floor 520 may deviate from the intended angle.

  On the other hand, in the embodiment, the origin setting mode S04 is executed between the first disinfecting water discharging step S02 and the second disinfecting water discharging step S05. That is, the control unit 30 executes the origin search mode in the middle of the washing place disinfection mode. This makes it possible to correct the deviation of the angle of the sanitizing water spouting section 10 with respect to the washing floor 520 during the washing germ removal mode. Therefore, it is possible to prevent the disinfecting water from being discharged in a state where the angle of the disinfecting water spouting section 10 with respect to the washing floor 520 is largely shifted. Thereby, it is possible to perform optimal water discharge according to the portion of the washing floor 520 stably for a long time.

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

FIG. 9 is a time chart for explaining the operation of the water removing apparatus for disinfecting water according to the present embodiment.
FIG. 9 shows the operations in the first disinfecting water discharging step S02 and the origin setting mode S04.
As shown in FIG. 9, in the first disinfecting water discharging step S02, the disinfecting water is continuously discharged from the disinfecting water discharging unit 10. Then, in the origin setting mode S04 of the water stopping step S03, the sterilized water discharging section 10 does not discharge the sterilized water.

In the “rotation of the disinfecting water spouting section” in the time chart, “1” indicates that the disinfecting water spouting section 10 is rotating from the origin 10 s toward the end position 10 e (normal rotation operation), and “0”. "Indicates that the sterilized water spouting section 10 has stopped rotating, and" -1 "indicates that the sterilized water spouting section 10 is rotating from the end position 10e toward the origin 10s (reversing operation). ).
As shown in FIG. 9, the disinfecting water spouting section 10 repeatedly rotates and stops. In the first disinfecting water spouting step S02, the disinfecting water spouting section 10 rotates intermittently in a direction from the origin 10s to the end position 10e. In the origin search mode S04, the sterilizing water spouting section 10 rotates intermittently in the direction from the end position 10e toward the origin 10s.

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

  Further, in the present embodiment, the disinfecting water spouting device 100 changes the amount of disinfecting water discharged and the rotation speed of the disinfecting water spouting section 10 according to the location of the washing floor 520. This will be described below.

FIGS. 11A and 11B are schematic plan views illustrating the operation of the sterilizing water spouting section of the present embodiment.
FIG. 11A is a schematic plan view illustrating the disinfecting water spouting section 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) at which the disinfecting water spouting section 10 rotates is divided into five different ranges D1 to D5. FIG. 11B shows regions R1 to R5 of the washing floor 520 corresponding to the ranges D1 to D5, respectively.

  For example, in the state ST1 in which the rotation angle is within the range D1, 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 to the region R2.

  The distance from the sterilized water spouting section 10 along the water discharge direction in the state ST1 to the wall surface 540 is shorter than the distance from the sterilized water spouting section 10 along the water discharge direction in the state ST2 to the wall surface 540. At this time, as shown in FIG. 9, the control unit 30 controls 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 section 10 along the water spouting direction in the state ST3 to the wall surface 540 is longer than the distance from the sterilized water spouting section 10 along the water spouting direction in the state ST2 to the wall surface 540. 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 the disinfecting water discharged in the rotation angle region where the distance between the disinfecting water spouting unit 10 and the wall surface 540 is relatively short is determined by the disinfecting water spouting unit 10 and the wall surface 540. The distance between the disinfecting water and the disinfecting water in the relatively long rotation angle region is smaller than the total amount of the disinfecting water.

  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 section 10 along the water spouting direction to the wall surface 540 in the state ST4 is the same as the distance from the sterilized water spouting section 10 along the water spouting direction in the state ST2 to the wall surface 540. Further, the distance between the region R4 and the drain outlet 521 is longer than the distance between the region R2 and the drain outlet 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 controls 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.

  Thus, when the distance between the sanitizing water spouting section 10 and the wall surface 540 is the same, the amount of the sanitizing water discharged downstream of the drainage gradient of the washing floor 520 is equal to the drainage gradient of the washing floor 520. Is smaller than the amount of sterilization water discharged to the upstream side.

  For example, the instantaneous flow rate of the sterilized water discharged from the sterilized water spouting section 10 is constant. Then, the control unit 30 changes the average rotation speed of the sterilized water spouting unit 10 according to the distance from the sterilized water spouting unit 10 to the wall surface 540 along the water spouting direction. Thus, the total amount of the sterilized water to be discharged can be changed according to the location of the washing floor. For example, the average rotation speed of the sanitized water spouting section 10 in the state ST1 is higher than the average rotation speed of the sterilized water spouting section 10 in the state ST3. As a result, the total amount of sterilized water discharged in state ST1 is smaller than the total amount of sterilized water discharged in state ST3.

  As shown in FIG. 9, when the sanitized water spouting section 10 repeatedly rotates and stops, the average rotation speed can be changed by changing the length of time during which the sanitized water spouting section 10 stops. it can. For example, the average rotation speed can be changed by keeping the angle and time during which the disinfecting water spouting section 10 rotates at one time and changing the time period in which the rotation operation is performed. For example, the period of the rotation operation in state ST1 is shorter than the period of the rotation operation in state ST3.

  In the time chart, the “water discharge state” is a schematic plan view showing a direction in which the sterilized water is discharged in each range of the rotation angle. Arrows in the plan view represent the flow of the sterilizing water discharged from the sterilizing water spouting section 10 and flowing on the washing floor 520 after hitting the wall surface 540. The direction of the arrow schematically represents the flowing direction of the sterilizing water, and the size of the arrow schematically represents the amount of the sterilizing water. In the time chart, “floor state” represents the amount of sterilized water present on the washing floor 520 in each state in a gray scale. This gray scale indicates that the deeper the color (closer to black), the greater the amount of sterilization water.

  As described above, the maximum water discharge distance at which the sterilized water spouting section 10 discharges the sterilized water is longer than the maximum distance between the sterilized water spout 10 and the wall surface 540. By rotating such a disinfecting water spouting section 10, disinfecting water can be discharged to the entire washing floor 520, and the entire washing floor can be disinfected.

  However, when the sanitized water spouting section 10 is rotated, the distance between the sanitized water spouting section 10 and the wall surface 540 along the water spouting direction changes. In such a state, if water is discharged in the same direction in all directions, the disinfecting water is removed on the washing floor 520 due to a change in the distance between the disinfecting water spouting section 10 and the wall surface 540 along the water discharging direction. An area where water is excessively discharged occurs. For this reason, a large amount of sterilized water is required.

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

  For example, when the distance between the sanitized water spouting section 10 and the wall surface 540 along the water spouting direction is short, as in the state ST1, the washing floor 520 is discharged from the sanitized water spouting section 10 and hits the wall surface 540. The volume of sanitizing water flowing over is relatively large. For this reason, even if the total amount of the sterilization water discharged in the state ST1 is reduced, the total amount of the sterilization water supplied per unit area can be maintained. Even if the total amount of sterilized water discharged in state ST1 is reduced, a sterilizing effect can be obtained.

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

  Further, in the embodiment, when the distance from the sanitizing water spouting section 10 to the wall surface 540 along the spouting direction of the sanitizing water is the same, the amount of the sanitizing water discharged to the upstream side of the washing floor 520 is determined by The amount of the disinfecting water discharged to the downstream side of the floor 520 is set to be smaller. The sterilized water discharged to the upstream of the washing floor 520 flows downstream 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 to the upstream side of the washing floor 520. Thus, even if the amount of sterilization water discharged to the downstream side of the washing floor 520 is reduced, the entire washing floor 520 can be sterilized.

  Further, when changing the amount of sterilized water to be discharged according to the site on the washing floor 520, a method of changing the instantaneous flow rate of the sterilized water can be considered. The instantaneous flow rate of the sterilized water discharged from the sterilized water spouting section 10 depends on the instantaneous flow rate in the sterilized water generation section 20. However, if the instantaneous flow rate in the sterilized water generator 20 is changed, the concentration of the component of the sterilized water generated in the sterilized water generator 20 changes. On the other hand, in the embodiment, the instantaneous flow rate of the sterilized water is kept constant, and the average rotation speed of the sterilized water spouting section 10 is changed. This makes it possible to change the total amount of the sterilized water discharged to a predetermined range of the washing floor 520 while keeping the concentration of the sterilized water constant.

  When changing the average rotation speed of the disinfecting water spouting section 10, if the rotation speed is too high, the torque may be insufficient and rotation may be defective. On the other hand, in the embodiment, the control unit 30 switches between a state in which the sterilizing water spouting unit 10 is in process and a state in which the sterilizing water spouting unit 10 stops rotating. The average rotation speed is changed by changing the length of time during which the disinfecting water spouting section 10 stops rotating. As a result, problems such as insufficient torque can be prevented.

  Next, the operation of the sterilized water spouting device 100 in the residual water discharge mode S07 will be further described with reference to FIGS.

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

  As shown in FIG. 12 and FIG. 13, the residual water discharge mode S07 has 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 S17, the sterilizing water spouting section 10 repeats the rotation and the stop. The disinfecting water spouting section 10 rotates intermittently from the end position 10e to the origin 10s. Thereby, the disinfecting water spouting section 10 vibrates. By this vibration, the surface tension of the sterilized water remaining in the sterilized water spouting section 10 can be reduced (destructed). Thereby, the sterilized water remaining in the flow path in the sterilized water spouting section 10 is discharged.

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

  When the amount of sterilized water discharged onto the washing floor 520 is small, the sterilized water becomes polka-dot-shaped residual water and does not easily flow to the drain port. On the other hand, when the disinfecting water is in the form of a film, the disinfecting water easily flows to the drain port along the drain gradient of the washing floor 520.

  In the embodiment, the sterilized water discharged from the sterilized water spouting section is dropped on the water film. Thereby, the disinfected water discharged from the disinfected water spouting section can flow to the drain port together with the disinfected water forming the water film. Therefore, even if the diameter of the spout is reduced in order to discharge the sanitized water in the form of highly discharged water, even after a long time has elapsed from the end of the operation of the sanitized water spouting device, the residual water is washed. It can be prevented from occurring on the floor.

  Further, in the first vibration step S17, the sterilizing water spouting section 10 is rotated from the end position 10e to the origin 10s. That is, the disinfecting water spouting section 10 is vibrated while changing the position where the disinfecting water remaining in the disinfecting water spouting section 10 falls. Thereby, the plane area of the region where the sterilized water falls onto the washing floor 520 can be increased. Therefore, it is possible to increase the possibility that the sterilized water dropped from the sterilized water spouting section 10 and the film-shaped sterilized water on the washing floor 520 come into contact with each other. Thereby, the sterilized water discharged from the sterilized water spouting section 10 can be more reliably guided to the drain port together with the sterilized water forming the water film.

  In the second vibration step S27, the control unit 30 causes the disinfected water discharging unit 10 to generate vibration different from the vibration generated in the disinfected water discharging unit 10 in the first vibration step 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. Thereby, the amount of the sterilizing water remaining in the sterilizing water spouting section 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. 13, the normal rotation operation and the reverse operation are alternately repeated.

  In the second vibration step, the repetition of the normal rotation operation and the reversal operation is performed after the protrusion 10q hits the rotation reference portion 10p. For this reason, the range in which the water outlet moves in the second vibration step is smaller than the range in which the water outlet moves in the first vibration step. Then, each time the normal rotation operation and the reversal operation are repeated, the protrusion 10q abuts on the rotation reference portion 10p. For this reason, a stronger vibration is generated in the water discharge port in the second vibration step than in the first vibration step. This makes it possible to further reduce the amount of the sterilized water remaining in the sterilized water spouting section.

Next, another embodiment of the present invention will be described with reference to the drawings.
FIGS. 14A and 14B are schematic plan views illustrating a disinfecting water spouting apparatus according to another embodiment of the present invention. FIG. 14A is a schematic plan view of the counter 530a provided with the disinfecting water spouting section 10 and the washing floor 520 viewed from above. FIG. 14B is a schematic plan view in which the vicinity of the disinfecting water spouting section 10 of FIG. 14A is enlarged.

  In this example, the shape of the counter 530a provided with the disinfecting water spouting section 10 is different from the shape of the counter 530 described above. Accordingly, the relative arrangement between the washing floor 520 and the sanitizing water spouting section 10 is different from, for example, the example shown in FIG.

  The rotation reference defining unit 534 serving as the rotation reference defining unit 15 is attached to a support member 533 located at a lateral end of the counter 530a. For this reason, the disinfecting water spouting section 10 is not located near the center in the horizontal direction of the counter 530a but at the end.

  That is, in this example, the disinfecting water spouting section 10 is provided not in the vicinity of the center in the horizontal direction of the washing floor 520 but in the lateral end of the washing floor 520. Except for this, the sanitized water spouting device shown in FIG. 14 is the same as the sanitized water spouting device 100 described in FIGS.

  As described above, even if the position at which the disinfecting water spouting section 10 is attached to the counter changes in this manner, the counter is taken into consideration in consideration of the relationship between the center of the counter and the position at which the disinfecting water spouting section 10 is attached. If the rotation reference defining portion 534 is formed, a rotation reference corresponding to the floor of the washing place can be defined. This makes it possible to perform optimal water discharge according to each part of the washing floor 520.

  Also in this case, as shown in FIG. 14A, the average rotation speed of the sanitized water spouting section 10 is changed according to the distance from the sanitized water spouting section 10 to the wall surface 540 along the water spouting direction. Thus, the total amount of the sterilized water to be discharged can be changed according to the location of the washing floor 520. In this way, it is possible to perform optimal water discharge according to each part of the washing floor 520.
