Japanese Patent Laid-Open No. 9-220273

  The water sprayed on the washing floor and the bathroom wall flows along the drainage gradient on the washing floor and is collected in a drain recess formed at the end of the washing floor. A drain trap is installed at the bottom of the drain recess, and a hair catcher for capturing hair is detachably attached to the opening of the drain trap. The user needs to remove the hair captured by the hair catcher as appropriate, but the hair catcher also generates slime due to soap residue and sebum dirt. When slime occurs, it becomes difficult to remove the hair from the hair catcher. Such slime adhering to the hair catcher can be suppressed by flowing sterilizing water.

  However, the drainage recess in which the drain trap is installed is covered with a drainage lid and is formed at the edge of the washing floor. With only the sterilizing water flowing in, the sterilizing water cannot be made to flow from the entire circumference of the drain recess. At the same time, since the sterilizing water does not flow from the entire circumference of the hair catcher, there is a problem that a part where the sterilizing water does not flow occurs in a part of the hair catcher.

  The present invention has been made in view of the above-mentioned problems, and allows the user to easily remove hair from the hair catcher by allowing the sterilizing water to flow throughout the portion of the hair catcher that captures the hair. I will provide a.

  According to an aspect of the present invention, a bathtub, a washing floor adjacent to the bathtub, a sterilizing water generating device that generates sterilizing water, and sterilizing water generated by the sterilizing water generating device are spouted to the washing floor. A bathroom sterilization unit provided with a sterilizing water spouting unit, wherein a drainage recess formed in a concave shape in a longitudinal sectional view is formed on an edge of the washing floor, and a bottom of the drainage recess is A drain trap having an opening at the top is installed, and a hair catcher having a mesh portion is detachably attached to the opening of the drain trap, and the sterilizing water spouting portion is entirely within the drain recess. Water is discharged so that sterilizing water flows from the periphery.

  According to the bathroom sterilization system according to the present invention, the bathroom sterilization unit that allows the user to easily remove the hair from the hair catcher by allowing the sterilization water to flow throughout the portion of the hair catcher that captures the hair. Can be provided.

  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 is provided with a downward slope for drainage into the drain recess 7. Here, the bathroom counter 5 is attached to the 2nd wall surface, and is arrange | positioned in the same height as the rim | limb 2a of the bathtub 2, or a low position.

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

The bathroom sterilizer 1 includes a control box 10, a functional unit 11, a spray nozzle 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 (sterilizing water generating device) that generates sterilizing water, is built in the bathroom counter, and a spray nozzle 12 that sprays 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 display 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 a washing faucet (not shown) are provided inside the bathroom counter 5. Among these, the water supply pipe 15 is branched and a tap water introduction pipe 15 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 15, 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.

  The water introduced by the tap water introduction pipe 17 is transformed into sterilized water in the functional unit 11 and sent to the spray nozzle 12 via 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. 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 spray nozzle 12 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. The water containing silver ions is sent to the spray nozzle 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 spray nozzle 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 dispersal nozzle vicinity of the washing-room floor 3 to the 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 first wall surface where the bathroom counter is installed on the back side from the spray nozzle 12, the second wall surface 4 near the first wall surface, or the vicinity of the first wall surface It is washed with water bounced off the bath apron 6 on the side, and sterilized water that bounces down and then flows down along the gradient of the washing floor 3. Thus, since the spray nozzle 12 is configured to rotate and discharge water, if the liquid ejection holes for the areas G, H, I, and J areas away from the spray nozzle are provided, the vicinity of the spray nozzle 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 spray the sterilizing water to the far side of the spray nozzle 12 only with the water pressure, there is a limit to the total hole area of the liquid ejection holes, but in this embodiment, the 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 spray nozzle 12 is installed in the vicinity of the wall surface 4 facing the bathtub 2 and the washing floor 3, that is, on the water opposite to the drain recess 7. There is no area that does not go around. Thus, since the spray nozzle on the side away from the drainage recess 7 in the bathroom counter 12 is attached, the sterilizing water can be directly discharged over the entire surface of the counter for a long time.

Moreover, since the spray nozzle 12 is installed in the lower part of the bathroom counter 5, the lower part of the bathroom counter 5 is shaded so that 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 recess 7 and the bath apron 6 hits the bath apron 6. Washed with sterilized water flowing down. As described above, the area that cannot be covered only by the sterilizing water flowing down the washing floor 3 (the edge on the side of the bath apron 6 in the drainage recess, and especially the central part of the sterilizing water is difficult to flow on the washing floor). However, the sterilizing water can be allowed to flow from the entire periphery of the drainage recess by directly discharging the sterilization water to the bath apron near the drainage recess. Here, the bath apron near the upper portion of the drain recess is a bath apron near the bath apron side edge that is not adjacent to the wash floor of the drain pit.

  FIG. 11 shows the structure in the drain recess 7. A drainage recess formed in a concave shape is formed in the drainage recess 7, and a drainage trap 100 having an opening at the top is installed at the bottom of the drainage recess 7. The hair catcher 90 which has a mesh part is attached so that attachment or detachment is possible. In the figure, the sterilizing water flowing into the drain recess 7 is shown by diagonal lines, but the sterilizing water flows from the entire circumference in the drain recess due to the flow flowing through the washing floor 3 and the flow falling on the bath apron 6. Come on. By spraying the sterilizing water spray nozzle 12 so that the sterilizing water flows into the drain recess from all around, the sterilizing water is brought into contact with the entire surface of the drain recess 7 to prevent the bacteria causing the slime from growing.

  FIG. 12 shows a hair catcher 90 attached to a drain trap. The hair catcher 90 includes an outer peripheral portion 90a, a mesh portion 90b, a central opening 90c, and a handle portion 90d. The central opening 90c allows water to flow through the opening to the drain trap if the mesh portion 90b is blocked with dust. The mesh part 90b of the hair catcher has an inclined part that inclines downward from the outer side toward the inner side. Since the sterilizing water can go down the inclined portion and reach the central opening 90c, the entire surface of the mesh portion 90b can come into contact with the sterilizing water. The hair is trapped in the mesh, where soap scum and shampoo are entangled, and bacteria are propagated, adding slime and making the cleaner feel uncomfortable, but according to the present invention, the mesh of the hair catcher Since sterilizing water can be brought into contact with the entire surface of the part and the hair becomes slimy, the cleaning load is reduced. FIG. 12B shows a cross section of the drain trap 100. The drain trap 100 has a sealing portion 100a and a hair catcher mounting portion 100b, and the outer peripheral portion 90a of the hair catcher is fitted into the mounting portion 100b. Prevent disengagement. The water that has flowed into the drainage recess 7 passes through the mesh part 90b of the hair catcher and flows into the sealing part 100a of the drainage trap. As described above, since the hair captured by the mesh portion does not become slimy, the user can easily remove the hair from the mesh portion while grasping the handle portion and removing the hair catcher.

  FIG. 13 shows an embodiment in which a drain recess is provided in the vicinity of the corner of the bathtub side end of the washing floor 3. Since the spray nozzle 12 rotates, the sterilizing water is sprayed in a circular shape around the nozzle. Depending on the nozzle outlet angle, the spray area of the floor surface of the sterilizing water becomes the GHIJ area. By discharging the sterilizing water in this way, the sterilizing water hits either the three wall surfaces or the bath apron 6. In the F area of the floor surface, there is not provided a spout for direct contact with the sterilized water on the floor surface, and the sterilized water that has fallen on the floor surface by hitting the wall flows to the drain port according to the inclination of the floor. The flow of sterilizing water that directly hits the GHIJ area from the spray nozzle 12 has a speed component that moves away from the drainage port, collides with the flow that flows from the wall, and causes the action of reducing the drainage speed of the sterilizing water. As described above, the sterilized water sprayed from the spray nozzle 12 can be prevented from flowing directly into the drain port, and the sterilized water can be retained on the floor as long as possible. As described above, the spray nozzle in the present embodiment can discharge water so as to counter the drainage gradient that is inclined downward toward the drainage recess in a situation where the sterilizing water is discharged on the washing floor.

  In the present embodiment, the sterilizing water is discharged so that the sterilizing water directly hits the bath apron and the first wall surface 42 near the upper portion of the drain recess. Accordingly, the sterilizing water that directly hits the first wall surface 42 where the bath apron 6 and the bathroom counter 5 are installed from the watering nozzle 12 is from two sides of the four sides of the drain recess 7 provided near the corner. Since it flows in and flows into the remaining two sides from the washing floor 3, the sterilizing water flows from the entire circumference into the drain recess.

Examples of the sterilizing water in the present invention include water containing a bactericidal substance or ions. 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.

According to the bathroom sterilization unit according to this embodiment described above, the following effects can be obtained.
By allowing sterilizing water to flow throughout the portion of the hair catcher that captures the hair, the user can easily remove the hair from the hair catcher.
Since the sterilizing water flows into the drain recess from the entire circumference, the inside of the drain port can be kept clean as a whole. If there is a part that does not come into contact with the sterilized water, bacteria will propagate there and become pink or yellow, causing discomfort to the user, but this is avoided in the present invention.

  Although embodiment of this invention showed the example which discharges sterilization water with a rotating nozzle, it is not restrict | limited to a rotating nozzle. For example, it is included in the scope of the present invention that sterilizing water is discharged from one fixed nozzle to the vicinity of the drain outlet so that the sterilizing water flows from all four sides of the drain recess. Moreover, it is also included in the scope of the present invention that sterilizing water is discharged by combining a plurality of nozzles so that the sterilizing water flows from all four sides of the drain recess.

  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.
