The bathroom sterilizer 1 includes a control box (control device) 10, a functional unit (sterilizer) 11, a watering unit 12 corresponding to a sterilizing water spouting unit, and a remote controller 13.
The control box 10 is installed behind the ceiling of the bathroom, and controls a later-described solenoid valve and electrolytic cell in the functional unit 11 according to an instruction from the remote controller 13. The functional unit 11 is a unit that generates sterilizing water, and is built in the bathroom counter, and a sprinkler 12 for spraying sterilizing water is connected to the tip of the functional unit 11.

  The remote controller 13 is installed on a wall surface such as a changing room in front of the bathroom, and includes a switch 13a and an LED 13b. When the switch 13a is turned on, the bathroom sterilizer 1 starts operating, and the LED 13b is turned on to indicate that the bathroom sterilizer 1 is operating.

  Inside the bathroom counter 5, as shown in FIG. 2, a water supply pipe 15 and a hot water supply pipe 16 for supplying water / hot water to a washing faucet (water discharger) are provided. Of these, the water pipe 15 is branched by a water pipe branching section 75, and a tap water introduction pipe 17 that supplies water to the functional unit 11 is connected thereto. A stop cock 18 is provided in the middle of the tap water introduction pipe 17, and by closing the stop cock 18, when removing the functional unit 11, it will not hinder normal use of the bathroom. It has become.

  A bathtub water conduit 70 for guiding bathtub water to the functional unit 11 is provided, and a pump 71 is installed on the way. A strainer 72 is provided in front of the pump to capture foreign matters such as dust having a large diameter. The filter (not shown) attached to the bathtub water intake 76 installed in the bathtub 2 and the strainer 72 capture hair, dust, etc. in the bathtub water and prevent malfunction of the pump. The bathtub water conduit 70 joins the functional unit 11 at the junction 73, and a check valve 74 for the bathtub water conduit is provided in the front stage of the junction 73. The check valve 74 for the bathtub water conduit can pass tap water from the tap water introduction pipe 17 to the functional unit 11 to generate sterilizing water, and tap water from the junction 73 to the bathtub water conduit 70 side. To prevent from entering.

  The piping diagram described above is summarized in FIG. The water pipe 15 is branched at the water pipe branching section 75, one is discharged to a washing faucet (not shown), and the other is discharged from the watering section 12 as sterilized water. A hot water supply pipe 16 is also connected to the washing faucet. The tap water branched at the water pipe branching section 75 is discharged from the water spraying section 12 through the stop cock 18, the electromagnetic valve 22 (switching valve), the merging section 73, and the electrolytic cell 26. When using bathtub water as sterilizing water, the solenoid valve 22 is closed and the pump 71 is operated. The bathtub water passes through the bathtub water guide channel 70, passes through the junction 73 and the electrolytic cell 26, and is discharged from the sprinkler 12. The operation of the solenoid valve 22, the pump 71, and the electrolytic cell 26 is controlled from the control box 10.

  The water introduced by the tap water introduction pipe 17 is transformed into sterilized water in the functional unit 11, and is sent to the sprinkling unit 12 through the sterilized water outlet pipe 19.

  FIG. 4 shows the strainer part. The strainer 72 is made of a porous cylinder such as a wire mesh. The rust is filtered and captured by the porous cylinder, and the filtered bathtub water is sent to the pump 71. The strainer 72 is installed in the bathtub water conduit 70 with the tube stopper 80 removed. 4A shows a state in which the strainer 72 is not in the pipe, and FIG. 4B shows a state in which the strainer 72 is installed in the pipe. When the strainer 72 is installed, the attachment / detachment detection means 79 operates. In FIG. 4, the movable part 79 b of the attachment / detachment detection unit 79 comes close to the reception unit 79 a of the attachment / detachment detection unit and the current flows through the attachment / detachment detection unit as the strainer is installed. An example is the use of magnets as the material for the movable part 79b and the receiving part 79a.

  As shown in FIG. 5A, the functional unit 11 includes a solenoid valve 22, a constant flow valve 23, an air release valve 24, in order in the case 20 through an inlet 21 connected to the tap water introduction pipe 17. The check valve 25 and the electrolytic cell 26 are communicated, and the electrolytic cell 26 is connected to the sterilizing water outlet pipe via the outlet 27. Moreover, bathtub water flows in into a functional unit from the junction 73. The inflow port 21 and the outflow port 27 are installed so as to be disposed on the front end side of the bathroom counter, and the shafts of the inflow port and the outflow port are respectively disposed at diagonal positions. The pipe part for communicating the inlet and outlet through the electrolytic cell goes straight from the inlet to the rear end side of the bathroom counter, and goes straight from the outlet to the rear end side of the bathroom counter. The return path part is bent in a U-shape to communicate the end part of the return path part and the bathroom counter rear end part of the return path part, and attached so that the return path part is disposed at a higher position than the forward path part. And a bent portion.

The functional unit 11 has a waterproof structure by filling the case 20 with a urethane resin 28. Thereby, the waterproofing of the terminal part of an electrical component and the water leakage from a water flow part are prevented.
Further, as shown in FIG. 5 (b), in order to minimize the size of the functional unit 11, the axes of the inlet 21 and the outlet 27 are disposed so as to be diagonal to the case 20.

  When the switch 13 a of the remote controller 13 is pressed, the electromagnetic valve 22 is opened and closed according to an instruction from the control box 10. Then, when the electromagnetic valve 22 is opened, water is passed, and the flow rate is kept constant by the constant flow valve 23. Thereby, the density | concentration of the produced | generated sterilization water is kept constant, At the same time, the water pressure of the sterilization water sprayed from the sprinkling part 12 is also kept constant, and it becomes possible to spray sterilization water in a desired range. .

  When the water flow state is reached, energization of the electrode 29 of the electrolytic cell 26 is started, and the electrode 29 is electrolyzed to generate silver ions. Water containing silver ions is sent to the sprinkler 12 as sterilizing water. The sterilized water thus generated is prevented from flowing back to the water supply pipe 15 by the check valve 25.

  The air release valve 24 is closed when energized (solenoid valve is open) to prevent water from leaking to the outside, and is open when standby (solenoid valve is closed). The downstream side of 25 is replaced with air. This prevents residual water from remaining in the electrolytic cell 26.

  The electrode 29 of the electrolytic cell 26 is formed of silver, a silver alloy, or a silver-plated metal, and silver ions are generated when the electrode 29 is electrolyzed. As shown in FIG. 6A, the electrodes 29 are installed in a positional relationship such that the electrodes 29 are horizontal. Thereby, as shown in FIG.6 (b), the conduction | electrical_connection state of the electrode by the surface tension of residual water is avoided at the time of standby. By doing in this way, even if an electrolytic cell is made compact (thickness is made thin), it can avoid that an electrode will be in a conduction | electrical_connection state by the surface tension of residual water at the time of standby.

  As shown in FIG. 7, the water sprinkling unit 12 is roughly composed of a body 30 connected to the sterilizing water outlet pipe 19 and a rotating body 31 pivotally supported at the tip thereof. The rotating body 31 is also divided into an upper member 32 and a lower member 33, and is rotatably attached to the tip of the body 31 by a fixing screw 35 via a washer 34 (see FIG. 9). Since the rotary body 31 is formed so as to be removable and dismountable in this way, the inside thereof and the tip of the body 30 can be cleaned.

  As shown in FIG. 8A, the rotating body 31 (lower member 33) is provided with four to eight liquid ejection holes 33a, 33b, 33c, and 33d. Since these liquid ejection holes 33a, 33b, 33c, and 33d are provided with the same distance from the rotation center of the rotating body 31 in the same direction, the liquid jet holes 33a, 33b, 33c, and 33d are rotated by the water flow when the water flows. Can be sprayed evenly.

  Among these, the liquid ejection hole 33a opens horizontally as shown in FIG. 8B, but the liquid ejection hole 33b opens at an elevation angle of 4 ° as shown in FIG. 8C. Further, as shown in FIG. 8 (d), the liquid ejection hole 33c opens at an elevation angle of 8 °, and the liquid ejection hole 33d opens at an elevation angle of 12 ° as shown in FIG. 8 (d).

Thereby, it can spread evenly from the water sprinkling part vicinity of the washing place floor 3 to a distant place. In addition, the elevation angle of each liquid ejection hole is appropriately determined according to the size of the washing floor to be sprayed.
By the way, as shown in FIG. 9, the tip end of the body 30 is formed by stepping the tip end 30 b having the diameter D2 further ahead of the shaft tip 30 a having the diameter D1. Correspondingly, the upper member 32 is formed with an insertion hole 32a having a diameter D1 'through which the shaft tip 30a can be inserted, and the lower member 33 is inserted with the shaft tip 30a through which the most distal end 30b can be inserted. An insertion hole 33e having an impossible diameter D2 '' is formed.

  This prevents the upper member 32 and the lower member 33 from being attached upside down by mistake after disassembling the rotating body 31, so that the liquid ejection holes 33b, 33c, 33d can secure an elevation angle and are always upward. Open to the direction.

  The bathroom sterilization system according to the present embodiment is configured as described above, and the sterilized water spray state will be described below. FIG. 10 is a plan view showing a sprayed state of sterilizing water, and FIG. 11 is an elevation view.

  The area G shown in FIG. 10 is an area where sterilizing water is mainly sprayed from the liquid ejection holes 33a having an elevation angle of 0 °, and the area H is mainly sterilizing from the liquid ejection holes 33b having an elevation angle of 4 °. The areas where water is sprayed, similarly the areas I and J, are areas where sterilized water is mainly sprayed from the liquid ejection holes 33c and 33d having elevation angles of 8 ° and 12 °, respectively. As described above, the sterilizing water can be sprayed over a wide range by changing the elevation angles of the liquid ejection ports 33a, 33b, 33c, and 33d.

  On the other hand, the sterilizing water is not sprayed directly on the area F shown in FIG. In this area, as shown in FIG. 11, the second wall surface 42 on which the bathroom counter is installed on the back side from the sprinkler 12, the first wall surface 4 near the second wall surface, or the second wall surface The water is rebounded by hitting the bath apron 6 in the vicinity, and after rebounding, it is washed with sterilized water flowing down along the gradient of the washing floor 3. Thus, since the sprinkling part 12 rotates and discharges water, if the liquid ejection holes for the areas G, H, I, and J areas away from the sprinkling part are provided, the vicinity of the sprinkling part 12 is inevitably provided. A large amount of sterilized water will flow on the floor of the washroom. Thereby, it becomes possible to spread the sterilizing water over the entire surface of the washing floor. In particular, in order to disperse sterilizing water to the far side of the sprinkler 12 only with tap water pressure, there is a limit to the total hole area of the liquid ejection holes, but in this embodiment, areas G, H, Since only the liquid ejection holes for the I and J areas are sufficient, the sterilizing water can be spread over the entire surface of the washing floor with only tap water pressure.

  In this respect, the water sprinkling section 12 is installed on the water in the vicinity of the wall surface 4 facing the bathtub 2 and the washing floor 3, i.e., at a position diagonal to the drain outlet 7. There is no area that does not turn around.

  Moreover, since the water sprinkling part 12 is installed in the lower part of the bathroom counter 5, the lower part of the bathroom counter 5 is shaded, and the sterilizing water does not rotate.

  On the other hand, since the elevation angle of the liquid outlet 33d is kept below a certain level, it is not economically spread over a wide area and is economical. As shown in FIG. Since the height of the rim 2a is not exceeded, sterilizing water is not applied to the bath lid.

  Further, since the sterilizing water is also sprayed toward the bath apron 6, as shown in FIG. 12, the gap formed between the drain lid 8 on the drain port 7 and the bath apron 6 hits the bath apron 6. Washed with sterilized water flowing down. As described above, an area that cannot be covered only with the sterilizing water flowing down the washing floor 3 (the edge on the side of the bath apron 6 at the drainage outlet, and particularly, the central part thereof is difficult to flow the sterilizing water flowing on the washing floor). can do.

  The water sprinkling unit 12 may be a fixed nozzle 77 that sprays cleaning water over a wide range. Bactericidal water is discharged from the fixed nozzle 77 as shown in FIG. 13 toward the washing floor 3. As shown in FIG. 13, if the washing water is spouted near the wall on the opposite side of the drainage port 7, the washing water can be flowed using the inclination toward the drainage port of the washing floor 3, so that the washing floor 3 on almost the entire surface It becomes possible to contact the sterilized water.

  FIG. 14 is a flowchart showing an embodiment of the present invention. When the bathroom sterilization SW is turned on, the bath water is detected. The detection method is to detect the water pressure in the bath outlet pipe 47 and the bath return pipe 48 by a pressure sensor (not shown) installed in the water heater 44, and when the bath water is present, the water pressure is high. If there is no, use the low water pressure. Moreover, a water detection sensor may be provided in the bathtub water conduit 70 to detect the bathtub water.

When the bath water is detected, the strainer attaching / detaching detecting means 79 detects the strainer. When the presence of the strainer is detected, the pump 71 is driven to pump the bath water to the functional unit 11. At this time, the solenoid valve 22 is closed. The sterilizer is turned on, the energization of the electrolytic cell 26 is started, and silver ions are eluted from the electrode 29 into the water. When the timer counts the predetermined time T ₀ , the pump 71 is closed and the sterilizing water generator is stopped. The predetermined time for discharging the sterilizing water is set to the time T ₀ for uniformly cleaning the entire washing area.

When bath water is not detected or when a strainer is not detected, the electromagnetic valve 22 is opened, the sterilizing water generating device is turned on, and the sterilizing water generated from the tap water is discharged to the washing place for a predetermined time T ₁ . T ₁ is set to a time for almost completely replacing the inside of the washing floor 3 and the drain with the sterilizing water. However, when there is no bath water, the time T ₁ may be set shorter than the case where there is no bath water. In addition, you may provide a constant flow valve in the watering part side from the confluence | merging part with the water supply pipe line in a water conduit. By providing the constant flow valve at this position, it is possible to make the amount of water sprayed constant when water is sprayed using bathtub water and when water is sprayed using clean water. Unlike tub water bathed by humans, sterilized water generated from tap water that does not contain organic substances such as sebum replaces the water in the washroom floor and drain outlet almost completely, thereby causing bacteria-caused slime and odors. Can be suppressed for a long time.

  Further, it was found in the process of the present invention that the silver ion sterilized water described in this example tends to darken when attached to a mirror or a faucet. On the other hand, I found that even if it hits the washing floor, wall surface, or bath apron, it doesn't darken. The reason why the water spraying part 12 of the silver ion water is installed under the bathroom counter 5 is that the bathroom counter serves as a barrier and the silver ion water is not applied to the mirror or the faucet installed above the bathroom counter. The reason why the fixed nozzle 77 is provided in front of the bathroom counter 5 and the silver ion water spouting water is discharged toward the washing floor is to prevent the silver ion water from being applied to the mirror and the faucet. All embodiments in which both the rotating nozzle and the fixed nozzle are installed at a position where the silver ion water to be discharged does not reach the mirror or the faucet are included in the present invention.

  As sterilization water in a present Example, the water containing a bactericidal substance or ion can be illustrated other than silver ion water. Specifically, free chlorine, antibacterial metals (for example, copper, zinc, etc.) or their ions, ozone, ozone-containing water, combined chlorine, organic chlorine-based disinfectant, organic phosphate-based disinfectant, veloxocarbonate ion or its Examples thereof include salts and alcohol-based disinfectants.

In addition, according to the bathroom sterilization system by this embodiment mentioned above, the following effects are acquired.
It is a bathroom sterilization system capable of saving water using bath water, and can provide a bathroom sterilization system capable of preventing problems caused by the adhering of coarse garbage such as hair to a pump or a sterilizer.
