Japanese Patent Laid-Open No. 9-220273

  However, in Patent Document 1, since sterilizing water is sprayed not only on the washing floor but also on the entire bathroom such as the bathroom wall, the sterilizing water may be applied to glossy metals such as mirrors and faucets. If sterilizing water adheres to a mirror or faucet for a long time, there is a risk of darkening or corrosion, which is not preferable. Therefore, it is conceivable to spray the sterilizing water so that the mirror and the faucet do not cover the sterilizing water. However, in that case, there is a possibility that the bacteria may propagate in the portion where the sterilizing water is not applied.

  Moreover, in order to suppress generation | occurrence | production of the microbe of the part which does not sprinkle sterilizing water, there exists the method of drying the inside of a bathroom using a bathroom dryer. However, if the drying operation is performed after spraying the sterilizing water in the bathroom, the sterilizing water of the part sprayed with the sterilizing water will also evaporate in a short time, and the sterilizing water cannot be retained for a long time. was there.

  The present invention provides a bathroom sterilization system capable of retaining sterilization water on a washing floor for a long time and using a bathroom dryer to suppress the generation of bacteria in areas where sterilization water is not applied, such as walls and ceilings. provide.

A bathroom sterilization system characterized by discharging sterilizing water is provided.

  According to the present invention, sterilizing water can be retained on the washing floor for a long time, and bathroom sterilization that can suppress the generation of bacteria in portions where sterilizing water is not applied, such as walls and ceilings, using a bathroom dryer. Provided system.

An embodiment of a bathroom sterilization system 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 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 draining into the drain pit 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 dryer 44 is installed behind the ceiling of the bathroom, is connected to the exhaust duct 45, and receives a signal from the operation remote controller 47 through the communication line 46.

  The operation of the bathroom dryer 44 will be described with reference to FIGS. The operation remote controller 47 includes a ventilation switch 49, a drying switch 50, a heating switch 51, and a cool air switch 52, and a stop switch 48 that stops each operation. When the ventilation switch 49 is pressed, the ventilation / circulation fan 61 is actuated, and the air in the bathroom is sucked from the intake port 60 and is discharged from the exhaust duct 45 to the outside through the ventilation air passage 64. At this time, the flow path switching damper 63 moves to a position where the circulation air path 66 is blocked. When the drying switch 50 is pressed, the flow path switching damper 63 moves to an intermediate position between the ventilation air passage 64 and the circulation air passage 66, and the ventilation / circulation fan 61 and the electric heater 65 remove the air in the bathroom that has been taken in. A part of the air is discharged to the exhaust duct, and the remaining air is warmed by the electric heater 65 and returned to the bathroom. When the cool air switch 52 is pressed, the electric heater 65 is turned off, and the ventilation / circulation fan and the flow path switching damper are the same as in the drying operation. When the heating switch 51 is pressed, the flow path switching damper 63 closes the ventilation air path 64, operates the electric heater 65, and circulates while heating the air in the bathroom. The number display means 57 of the operation remote controller 47 displays the clock display and the driving time of each operation, matches the clock number with the clock switches 54a and 54b, and reserves the start time and stop time of each operation with the reservation switch 55. Or check. The clothes drying mode of the present invention corresponds to a mode in which the bathroom dryer 44 operates when the drying switch 50 is pressed.

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. The voice means 13c is provided, and when the switch 13a is pressed, the user is asked whether or not to perform the drying mode of the bathroom dryer 44.

  Inside the bathroom counter 5, as shown in FIG. 3, 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. 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 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.
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 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. 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 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. 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 where the bathroom counter is installed on the back side from the water sprinkling unit 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 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.

FIG. 12 is a flowchart for performing sterilizing water spouting from the watering part after performing the drying mode of the bathroom dryer. When full sterilization SW is turned ON, bathroom dryer for drying mode predetermined time T _0. During this time, water drops on the walls, ceilings, and bathtubs where the sterilizing water is not applied are dried. After the drying mode is turned off, the electromagnetic valve 22 is opened to start discharging the sterilizing water. 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.

In the embodiment of FIG. 13, when the bathroom sterilization SW is turned on, the user is asked whether the bathroom dryer is in the drying mode. When the drying mode is performed, the bathroom sterilization SW is pressed again. And drying mode for a predetermined time T ₀ by Bathroom dryer, wall and ceiling in the bathroom, drying took water droplets parts sterile water, etc. in the bathtub is not applied. After the drying mode of the bathroom dryer is turned off, the electromagnetic valve 22 is opened and water discharge of sterilizing water is started. Over a predetermined time T _1, a washing place or a portion close to the bathroom floor inner wall, and sprinkling the sterilizing water to the bus apron, replacing the drainage mouth sterile water.

  It was found in the course of the research 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.

  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, this invention may be the form which sprinkles sterilization water not only in a washing place but also in a bathtub, and if it is a form which sprays sterilization water below glossy parts, such as a mirror and a faucet, good.

In addition, according to the bathroom sterilization system by this embodiment mentioned above, the following effects are acquired.
Disclosed is a bathroom sterilization system that can retain sterilization water on a washing floor for a long time and can suppress the generation of bacteria in a portion not exposed to sterilization water such as a wall surface or a ceiling using a bathroom dryer.

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, but these embodiments are also included in the scope of the present invention.
