Description

  The present invention relates to a bathroom sterilization system that suppresses the generation of bacteria on the floor of a washing place and in a drain trap by flowing sterilizing water in the wash place and the drain trap of the bathroom.

2. Description of the Related Art Conventionally, bathroom antifouling devices have been proposed that suppress the generation of bacteria by spraying sterilizing water containing bactericidal substances or ions on bathroom walls and washroom floors (see, for example, Patent Document 1).
In such a bathroom antifouling device, sterilizing water is sprayed on the bathroom wall or washroom floor in the form of mist, granules, flowing water, etc., so that dirt generated on the surface of the bathroom wall or washroom floor caused by bacteria is removed. It is disclosed that it can be prevented. Further, the sterilizing water sprayed on the washing floor or bathroom wall flows along the drainage gradient on the washing floor, is attached to the washing floor, and is collected in a drain trap that can form a sealed water.
Japanese Patent Laid-Open No. 9-220273

  However, since Patent Document 1 does not consider the suppression of the generation of bacteria in the drain trap, there is a problem that the propagation of bacteria in the drain trap cannot be sufficiently suppressed. In general, the sealed portion of the drain trap immediately after bathing contains a large amount of organic contaminants such as sebum, shampoo, soap scum, etc., and therefore is in an environment in which bacteria are very easy to propagate. Even if a small amount of sterilizing water is allowed to flow in a state where such organic contaminants are present in a large amount, the sterilizing effect is reduced. Accordingly, it is required to sufficiently replace the sealed water remaining in the drain trap immediately after bathing with sterilizing water.

  However, since the sterilizing water flows into the drain trap via the washing place, there is a possibility that the inside of the trap cannot be completely replaced with the sterilizing water.

  This invention is made in view of the above-mentioned problem, and provides the bathroom sterilization system which can disinfect the whole on a washing-room floor and the inside of a drain trap, and can fully replace the inside of a drain trap with sterilization water especially.

  According to one aspect of the present invention, a sterilization process for discharging sterilizing water toward the entire surface of the washroom floor, and sterilizing water is concentrated and discharged at or near the drain outlet formed on the floor of the washroom. And a drainage sterilization process, and the control apparatus performs the drainage sterilization process after performing the washing place sterilization process.

  According to the bathroom sterilization system according to the present invention, it is possible to provide a bathroom sterilization system capable of sterilizing the entire wash floor and the inside of the drain trap, and particularly capable of sufficiently replacing the inside of the drain trap with sterilizing water. it can.

An embodiment of a bathroom sterilization unit according to the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an overall outline of a bathroom sterilization system according to this embodiment.
This bathroom sterilization system includes a bathtub 2, a washing floor 3 adjacent to the long side of the bathtub 2, and a bathroom horizontally installed on the first wall 4 facing the bathtub 2 across the washing floor 3 from the bathtub 2 side. It comprises a counter 5 and a bathroom sterilizer 1. The washing floor 3 has a downward slope for drainage toward the drain outlet 7. Here, the bathroom counter 5 is attached to the second wall surface 42 and is disposed at a position lower than the rim 2 a of the bathtub 2.

  Also, in this bathroom, there are a bath apron 6 covering the area from the edge of the bathtub 2 side of the washing floor 3 to the edge of the washing floor 3 side of the bathtub 2, and the bathroom floor 3 on the edge of the bathtub 2 side of the washing floor 3 A drainage port 7 is provided which is formed one step lower and in which a drain trap (not shown) is installed. A clearance is provided on the upper surface of the drainage port 7 so that water on the washing floor can flow into the drainage port 7. Then, the drain lid 8 is placed.

  The bathroom sterilizer 1 includes a control box (control device) 10, a functional unit 11, a washing area sterilizing watering portion 12 for discharging sterilizing water to the entire washing area, and a drainage outlet sterilizing watering for discharging the sterilizing water intensively at the outlet. A unit 73 and a remote controller 13 are provided.

  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 is connected to a washing place sterilizing watering part 12 for spraying sterilizing water and a drain outlet sterilizing watering part 73 at its tip.

  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.

  As shown in FIG. 2, a water supply pipe 15 and a hot water supply pipe 16 for supplying water / hot water to the washing faucet are provided inside the bathroom counter 5. The water supply pipe 15 is branched by a water supply 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 hinder normal use of the bathroom. It has become.

  A branch 40 is provided at the exit of the functional unit 11 at the tip of the sterilizing water outlet pipe 19. The water introduced by the tap water introduction pipe 17 is transformed into sterilized water in the functional unit 11, passes through the branching part 70 via the sterilizing water outlet pipe 19, and passes through the branch valve 70 via the electromagnetic valve 71 and is washed at the washing place sterilization watering part 12. Or water is discharged from the drain outlet sterilizing watering part 73 via the electromagnetic valve 72.

  The piping diagram described above is summarized in FIG. The water supply pipe 15 is branched at the water supply pipe branching section 75, one is divided into the washing faucet 77, and the other is divided at the branching section 70, and becomes sterilized water from the washing place sterilization watering part 12 or the drain sterilization watering part 73. The water is discharged. Switching of the sterilizing water discharge is performed by the electromagnetic valves 71 and 72.

  As shown in FIG. 4A, the functional unit 11 includes a solenoid valve 22, a constant flow valve 23, an air release valve 24, The check valve 25 and the electrolytic cell 26 are communicated. 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 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 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. 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 the switch 13 a of the remote controller 13 is pressed, the electromagnetic valve 22 is opened and water is passed by an instruction from the control box 10, and the flow rate is kept constant by the constant flow valve 23. Accordingly, the concentration of the generated sterilizing water is kept constant, and at the same time, the water pressure of the sterilizing water sprayed from the sprinkling unit is also kept constant, and 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 as sterilized 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.

  From the washing place sterilization watering part 12, sterilization water is sprayed. As shown in FIG. 6, the washing place sterilization watering part 12 is roughly composed of a body 30 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.

  FIG. 9 is a plan view showing a sprayed state of the washing place sterilizing watering part 12, 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 42 on which the bathroom counter is installed on the back side from the washing place sterilizing watering part 12, the first wall 4 near the second wall, or the second It is washed with water that bounces off the bath apron 6 near the wall surface of the wall and sterilized water that bounces down and then flows down along the gradient of the washing floor 3. Thus, since the water sprinkling part 12 rotates and discharges water, if the liquid ejection holes for the areas G, H, I, and J areas away from the water sprinkling part are provided, the sterilization water sprinkling part sterilized in the washing place is necessarily formed A large amount of sterilized water will flow on the floor near the washing ground. 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 washing place sterilizing water spraying part 12 only with water pressure, there is a limit to the total hole area of the liquid ejection holes, but in this embodiment, the areas G, Since only the liquid ejection holes for the H, I, and J areas are sufficient, the sterilizing water can be spread over the entire surface of the washing floor only with tap water pressure.

  In this respect, the washing field sterilization watering part 12 is installed on the water in the vicinity of the wall surface 4 facing the bathtub 2 and the washing field floor 3, that is, at a position diagonally opposite to the drain port 7, so However, there is no area where sterilizing water does not rotate.

  Moreover, since the washing place sterilization watering part 12 is installed in the lower part of the bathroom counter 5, the lower part of the bathroom counter 5 is shaded and sterilization 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. 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.

  As shown in FIG. 12, the drain outlet sterilization sprinkler 73 has a structure for discharging the sterilized water in the vicinity of the drain outlet. The water discharge port 74 is directed to the water discharge port, and as shown in FIG. 13, the sterilizing water is concentrated and discharged near the water discharge port.

  The washing place sterilization watering part 12 may be a fixed nozzle that spreads sterilizing water over a wide range. As shown in FIG. 14, if the sterilizing water is discharged near the wall opposite to the drainage port 7, the sterilizing water can flow using the inclination toward the drainage port of the washing ground floor 3. It becomes possible to contact the sterilized water.

FIG. 17 is a flowchart when the washing place sterilization switch is turned ON. When the washing place sterilization SW is turned on, the electromagnetic valve 22 and the electromagnetic valve 71 are opened, and a washing place sterilization process is performed in which the sterilizing water is sprinkled from the washing place sterilizing watering unit 12 to the entire surface of the washing place floor 3. When the timer counts the predetermined time T ₀ , the solenoid valve 22 and the solenoid valve 71 are closed, the energization of the electrolyzer 26 of the sterilizing water generating device is stopped, and from either the washing place sterilizing watering unit 12 or the drain sterilizing watering unit 73. A standby process is performed to prevent the sterilizing water from being discharged. This standby process is set to a time at which most of the sterilized water discharged in the washing place sterilization process is discharged to the drain outlet. After the predetermined time T ₁ elapses from the end of the water discharge of the sterilizing water, open the solenoid valve 22 and the electromagnetic valve 72 performs energization of the electrolytic cell 26 of the sterilizing water producing device again, draining sterilizing water inlet sterilizing nozzle unit 73 Concentrate water near the drainage outlet. When the timer counts a predetermined time T _2, closing the solenoid valve 22 and the electromagnetic valve 72, and ends the operation to stop the sterilizing water producing device. It is preferable to close the solenoid valve after stopping the sterilizing water generator. Because the sterilizing water generation is stopped just before the solenoid valve is closed (about 1 second), the remaining water does not contain sterilizing components, silver ions in this embodiment, and the black spots that can be caused by silver ions are discharged into the water discharge portion. And the possibility of creating a floor under the water discharge section is eliminated. Preferably, the solenoid valve 72 is closed after the solenoid valve 22 is closed for about 5 seconds. This is because the residual water in the water channel pipe is removed from the drain outlet sterilization watering part 73 by the action of the air release valve 24. The predetermined time T ₁ described above is equivalent to the waiting process, the time to discharge most of the sterilizing water spouted in washing space sterilization step to the drain outlet. After draining dirt components such as sebum and soap scum on the floor 3 to the drainage outlet, water is discharged from the drainage sterilization sprinkling unit 73 near the drainage outlet to completely remove the dirt components in the drain trap with sterilized water. Only the sterilized water which does not contain a dirt component can be retained in the drain trap. As a result, there is an effect of increasing the antifouling performance in the drain outlet.

  In the washing place sterilization process, the sterilizing component may be mixed only in the latter half without mixing the sterilizing component in the whole water discharge. In the washing place sterilization step, sterilized water may be sprayed in a mist form. By discharging water in a mist form, the sterilizing water can be retained on the floor of the washing place for a long time.

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. A form of spraying sterilizing water over the entire bathroom is also included in the embodiment of the present invention.

  In addition, according to the bathroom sterilization unit by this embodiment mentioned above, the following effects are acquired. It is possible to provide a bathroom sterilization system which can sterilize the entire washing floor and the inside of the drain trap, and in particular, can sufficiently replace the inside of the drain trap with sterilizing water.
