Scatter. A pump 71 is provided in the middle of the bathtub water conduit 70 to self-prime bathtub water.

The bathroom sterilizer 1 includes a control box (control device) 10, a functional unit 11, a sprinkling 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, is built in the bathroom counter, and has a sprinkler 12 that sprays the sterilizing water 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 tap water use switch 13a, a tap water use LED 13b, a bathtub water use switch 13c, and a bathtub water use LED 13d. When the tap water use switch 13a is turned on, the tap water enters the bathroom sterilizer 1 and starts operation, and the tap water use LED 13b is turned on to display that sterilizing water is being generated from the tap water. When the bathtub water use switch 13c is turned on, the bath water enters the bathroom sterilizer 1 and starts operation, and the bathtub water use LED 13d is lit to indicate that sterilizing water is being generated from the bathtub water. To do.

  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 connected to a tap water introduction pipe 17 that supplies water to the functional unit 11. 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 interfere with 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 the front stage 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 an electromagnetic valve 74 for the bathtub water conduit is provided in a stage preceding the junction 73. When the bathtub water use switch 13c is turned on, the electromagnetic valve 74 is opened and the pump 71 is operated to allow the bathtub water to enter the functional unit 11. A check valve may be provided between the electromagnetic valve 74 and the junction 73.

  The water transformed into the sterilizing water in the functional unit 11 is sent to the sprinkler 12 through the sterilizing water outlet pipe 19.

  The piping diagram described above is summarized in FIG. The water pipe 15 is branched at the water pipe branching section 75, one is to the washing faucet 77, and the other is from the water faucet 18, through the solenoid valve 22, the merging section 73, and the electrolytic bath 26 to discharge water from the sprinkling section 12. Is done. When the bathtub water is used as sterilizing water, the solenoid valve 22 is closed, the solenoid valve 74 is opened, and the pump 71 is operated. The bathtub water passes through the bathtub water conduit 70 and the junction 73 and the electrolytic cell 26. Water is discharged from the street sprinkler 12. The operation of the solenoid valve 22, the solenoid valve 74, the pump 71, and the electrolytic cell 26 is controlled from the control box 10.

  As shown in FIG. 4A, 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 19 via the outlet 27. Moreover, the bathtub water flows into the functional unit through the junction 73. The inflow port 21 and the outflow port 27 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 respectively 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 of the bathroom counter, and goes straight from the outlet to the rear 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. 4B, 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 sterilizing water is generated, the constant flow rate valve 23 keeps the flow rate constant. As a result, the concentration of the sterilizing water is kept constant, and at the same time, the water pressure of the sterilizing water sprayed from the sprinkling unit 12 is kept constant, so that the sterilizing water can be sprayed 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. 5A, the electrodes 29 are installed in a positional relationship such that the electrodes 29 are horizontal. Thereby, as shown in FIG.5 (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. 6, the water sprinkling unit 12 is 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. 8). 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. 7A, 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. 7B, but the liquid ejection hole 33b opens at an elevation angle of 4 ° as shown in FIG. 7C. Further, as shown in FIG. 7 (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. 7 (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. 8, the tip of the body 30 is formed by stepping the tip 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. 9 is a plan view showing a sprayed state of sterilizing water, and FIG. 10 is an elevation view.

  The area G shown in FIG. 9 is an area where sterilizing water is mainly sprayed from the liquid ejection holes 33a with an elevation angle of 0 °, and the area H is mainly sterilization from the liquid ejection holes 33b with 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. 10, 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 can be 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. 11, 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. In this way, an area that cannot be covered only with the sterilizing water flowing down the washing floor 3 (the edge of the drainage outlet on the side of the bath apron 6 and particularly near the center is difficult for the sterilizing water flowing on the washing floor to flow). 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. As shown in FIG. 12, 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 is almost entirely covered. It becomes possible to contact the sterilized water.

  The water sprinkling part 12 may have a shower shape that can be held and sprayed by a person. At that time, the shower hose is confiscated in the bathroom counter 5. A shower hose is connected to the tip of the sterilizing water lead-out pipe 19, and sterilizing water can be sprayed over a wider range according to the user's intention. Even when the sterilizing water is taken out of the bathroom and used, it becomes easy for the balls to receive the sterilizing water.

  FIG. 13 is a flowchart for generating and spraying sterilizing water using tap water. When the tap water use switch is turned on, the electromagnetic valve 22 is opened, a current is passed through the electrolytic cell 26, sterilizing water is generated for a predetermined time T1, and water is discharged from the water sprinkling unit 12.

  FIG. 14 is a flowchart for generating and spraying sterilizing water using bathtub water. When the bathtub water use switch is turned on, the electromagnetic valve 74 is opened, the pump 71 is operated, the current is supplied to the electrolytic cell 26, sterilizing water is generated for a predetermined time T2, and water is discharged from the sprinkling unit 12. The

The concentration of silver ions generated in the electrolytic cell 26 follows the Faraday equation. If the eluting silver ion concentration A (ppb), the current I (mA) flowing between the electrodes, the Faraday constant Z, the silver atomic mass M, and the flow rate Q (L / min) of the water flowing between the electrodes,
A = I x M x 60 x 1000 / Z / Q (1)
(1) is a theoretical formula in which silver ions are eluted at a current efficiency of 100%. In practice, since the silver ion concentration decreases due to chlorine ions Cl and the like in water, a current value that takes into account the decrease in efficiency flows. A desired silver ion concentration is obtained. The authors have set the control conditions with 100 ppb as a guideline as a silver ion concentration that suppresses bacterial growth in the bathroom floor and drain and keeps it clean for several weeks.

  In the present invention, when bath water is used for generating silver ions, the control conditions are set to use tap water for the purpose of compensating for the decrease in the sterilizing power of silver ions due to dirt derived from the human body contained mainly in the bath water, mainly organic matter. Shall be different. Considering the influence of silver ion elution inhibition by chlorine ions Cl dissolved from human sweat, the current value for energizing the electrolytic cell 26 in the case of using bath water is set larger than the current value in the case of using tap water. As a measure of the increase range of the current value, any current value within 2 times is set.

  The sterilizing water spraying time T2 in the case of using the bath water may be set longer than the sterilizing water spraying time T1 in the case of using tap water in consideration of the stain effect of the bath water.

  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.

  The embodiments described above are for illustrative purposes and do not limit the scope of the invention. Accordingly, those skilled in the art can employ embodiments in which each or all of these elements are replaced by equivalents thereof, and these embodiments are also included in the scope of the present invention.
