The bathroom sterilizer 1 includes a control box (control device) 10, a functional unit 11, a watering part 12 corresponding to a sterilizing water spouting part, 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. In addition, the remote controller 13 is provided with a notification means 13c, and when the switch 13a is pressed, if the water heater 44 is executing a hot water supply function or a cooking function, the user is alerted.

  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. Among these, the water supply pipe 15 is branched and a tap water introduction pipe 17 for supplying water to the functional unit 11 is connected. 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.

  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.

  As shown in FIG. 3A, 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 via 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. Here, the inflow port and the outflow port are installed so as to be arranged on the front end side of the bathroom counter, and the axes of the inflow port and the outflow port are arranged 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.
In addition, as shown in FIG. 3B, 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. 4A, the electrodes 29 are installed in a positional relationship such that the electrodes 29 are horizontal. Thereby, as shown in FIG.4 (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. 5, 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. 7). 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. 6A, 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. 6B, but the liquid ejection hole 33b opens at an elevation angle of 4 ° as shown in FIG. 6C. Further, as shown in FIG. 6 (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. 6 (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. 7, the tip of the body 30 is formed by a stepped end 30b of the diameter D2 further ahead of the shaft tip 30a formed of 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. 8 is a plan view showing a sprayed state of sterilizing water, and FIG. 9 is an elevation view.

  The area G shown in FIG. 8 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. 9, 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 part 12 is installed on the water in the vicinity of the wall surface 4 facing the bathtub 2 and the washing floor 3, that is, at a position diagonal to the drain pit 7, so that the sterilizing water is also provided in the vicinity of the water sprinkling part 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 can be kept below a certain level, it is not economically spread over a wide area and is economical, and 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. 10, the gap formed between the drain lid 8 on the drain pit 7 and the bath apron 6 hits the bath apron 6. Washed with sterilized water flowing down. In this manner, an area that cannot be covered only by the sterilizing water flowing down the washing floor 3 (the edge of the drainage pit on the side of the bath apron 6 and particularly the center thereof is difficult to flow the sterilizing water flowing on the washing floor). can do.

  FIGS. 11-14 is a flowchart which prohibits the sterilizing water spouting from a watering part, when the water heater is operating.

In FIG. 11, when the washing place sterilization SW is turned on, the solenoid valve is opened and water discharge of the sterilizing water is started only when the water heater does not execute the hot water supply function or the additional cooking function. That is, when the water heater is operating when the washing area sterilization SW is turned on, the solenoid valve is closed and the sterilizing water generator is not operated. By doing in this way, when the water heater is performing the hot water supply function or the additional cooking function, it is possible to indirectly recognize that the user is in the bathroom or that the user bathes immediately afterwards. it can. When the solenoid valve is opened and the operation of the sterilizing water generator is turned on, the timer is operated. When the timer counts a predetermined time, the solenoid valve is closed, the sterilizing water generator is stopped, and the operation is ended. The predetermined time for discharging the sterilizing water is set to a time T _{0 at} which the entire washing area is washed evenly and the water in the drain trap is almost completely replaced.

FIG. 12 is a flowchart for sending a washing place sterilization command when the device reaches a predetermined time. A timer is set at midnight when a person's bathroom is not normally used, and when the time comes and the water heater is not operating, the solenoid valve is opened and the sterilizing water starts to be discharged. The sterilized water is sprinkled on the washing place for a predetermined time, and after a predetermined time, the sterilized water generation and the electromagnetic valve are stopped to finish the operation. The predetermined time for discharging the sterilizing water is set to a time T _{0 at} which the entire washing area is washed evenly and the water in the drain trap is almost completely replaced.

  In this case, since the device automatically issues a signal for sterilization at the washing place, there is an advantage that the sterilizing water can be surely discharged every day. You may combine with the thing which a user turns ON sterilization water spouting SW after a user uses a bathroom manually. The antifouling effect of the bathroom is further enhanced by flowing sterilized water twice immediately after use in the bathroom and at night when the fungus activity is activated. The time at which the signal is transmitted may be arbitrarily input by the user, or the user's bathroom use time may be learned from the operation data of the water heater, and may be set to a time when the user does not use at night.

  In the embodiment of FIGS. 11 and 12, when the operation of the water heater is not detected when the washing place sterilization SW is turned on, the solenoid valve is opened and the sterilizing water generating device is exercised. However, since there is a possibility that the user is still in the bathroom, the operation may be started after a while after the operation of the water heater is not detected.

  In FIG. 13, when the washing place sterilization SW is turned on, when the water heater does not execute the hot water supply function or the additional cooking function, the electromagnetic valve is opened to start discharging the sterilized water. When the water heater is operating, the sterilizing water discharge command is deleted. The case where the washing field sterilization SW is ON includes a case where the control device automatically issues a sterilization water discharge signal at a predetermined time.

  In FIG. 14, when the washing place sterilization SW is turned on, when the water heater is not operated, the electromagnetic valve is opened to start discharging the sterilized water. When the water heater is operating, the notification means is turned on, and alerts whether there are any people in the bathroom. Thereafter, the device inquires of the user whether or not to perform sterilizing water spouting again, and when sterilizing water spouting OK is input, sterilizing water spouting is performed. In this case as well, the case where the washing place sterilization SW is turned ON includes a case where the control device automatically issues a sterilizing water discharge signal at a predetermined time.

  As an example of the notification means, a warning or notification may be given to the operator by displaying on a liquid crystal display device provided in the remote control or generating sound, sound, light, etc. from the remote control.

  As sterilizing water in a present Example, the water containing a bactericidal substance or ion can be illustrated. Specifically, free chlorine, antibacterial metals (eg, silver, copper, zinc, etc.) or their ions, ozone, ozone-containing water, combined chlorine, organochlorine-based disinfectant, organophosphate-based disinfectant, veloxocarbonate ion Or the salt, alcoholic disinfectant, etc. can be mentioned.

  Moreover, this invention is not limited to the washing place sterilization water discharge shown in the said Example by involving in a bathroom washing | cleaning apparatus. Implementation of the present invention also includes a form in which detergent is sprayed in the washing area, a form in which the detergent is sprayed in the bathtub, a form in which the inside of the bathtub is sterilized with sterilized water, a cleaning water containing detergent in the entire bathroom, and a form in which sterilized water is sprayed Included in the form.
