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 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 pit 7 is provided which is lower than the drainage pit 7 and is provided with a drainage trap (not shown). A clearance is formed on the upper surface of the drainage pit 7 so that water on the washing floor can flow into the drainage pit 7. Then, the drain lid 8 is placed.

  On the rim surface of the bathtub 2, a drain plug operation unit 40 that operates opening and closing of a drain plug (tub drain plug) 50 is provided, and controls the opening and closing of the drain plug 50 together with the drain plug operation transmission unit 49. Further, a drain plug open / close detection means (described in FIG. 13) for detecting the open / close state of the drain plug 50 is provided in the drain plug operation unit 40, and an electric signal corresponding to the opening / closing of the drain plug is transmitted to the control box 10. The

  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 an electromagnetic valve (switching means) and an electrolytic cell, which will be described later, 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 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, even when the functional unit 11 is removed, the normal use of the bathroom is not hindered. 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, 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. 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 side bath apron 6 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 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 pit 7. There is no area that does not turn around.

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 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 with 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 near the center is difficult for the sterilizing water flowing on the washing floor to flow). can do.

  The structure of the drainage part 60 is shown in FIGS. This is a drain trap having a so-called one-trap structure in which the drainage of the bathtub 2 side and the washing room 3 side merge. This drain trap structure was formed on the side of the trap body to connect the drainage pipe, and a trapezoidal trap body with a wash-basin drain inlet at the top, a water seal installed in the trap body A drain outlet and a bathtub water inlet formed on the side surface of the trap body for connecting a bathtub drain pipe communicating with the bathtub drain formed on the bottom surface of the bathtub are provided. Such a combined trapping drain trap having a one-trap structure can be surely sterilized by the present invention because only one drain trap is installed in the bathroom. In particular, by prohibiting the operation of discharging the sterilizing water to the washing place during or before the drainage of the bath water, the sterilizing water can stay in the drain trap for a long time. The sterilizing water inside is not replaced.

  FIG. 13 shows a mechanism related to the drain plug. A drain plug 50 for opening and closing a bathtub drain opening formed on the bottom surface of the bathtub 2 is provided, and a drain plug operation unit 40 is provided on the rim surface. The drain plug operation unit 40 has a push button 40a that is pushed downward with a finger when a person opens and closes the drain plug 50 on the outer surface, and a push button connection dedicated 40b that is linked to the movement of the push button 40a. 49 is informed of the movement of the push button 40a.

  The drain plug transmission section 49 has an outermost resin guide hose 49a having an inner diameter of 10 to 20 mm and a wall thickness of about 1.5 mm, and a release tube 49b having an outer diameter of about 3 mm is inserted therethrough. The release tube 49b also has a hollow structure, through which a release 49c having a thickness of about 1 mm passes. The release 49c moves back and forth in the release tube 49b in accordance with the movement of the push button, and mechanically pushes up the drain plug 50. The release tube 49b is preferably made of a material having a low frictional resistance and having a good durability and workability by rotating the release. The release 49c has a structure in which a thin stainless steel wire having a wire diameter of about 0.3 mm is spirally wound at a short pitch, is bent because it is soft, and can directly transmit the pushing force to the drain plug.

The drain plug 50 is attached to a drain plug support 51 which is pushed up by the release 49c. The drain plug support 51 is interlocked with the release 49 c via the mechanical mechanism 52.
The mechanical mechanism part 52 is connected and integrated with the support part 53, and has a structure in which it is fitted downward from the inner surface of the bathtub at the drain port part. A fitting projection 53a is provided at the lower end of the support part and cannot be easily removed after fitting.

  FIG. 13 shows an example in which a drain plug opening / closing detection means 55 as an opening / closing detection means is provided in the drain plug operation unit 40. This example uses the fact that the push button 40a is lowered when the drain plug is open, and the push button 40a is raised when the drain plug is closed. When the magnetic member 46 is provided in the push button portion and the position detecting means 47 is provided on the operation lower end surface of the push button. When the drain plug 50 is opened and the magnetic member 46 approaches the position detecting means 47, the position detection signal is transmitted to the control box 10. It is transmitted to.

  FIG. 14 shows another example of the bathtub drainage detection means for detecting the presence or absence of bathtub water using a water heater. The figure shows a state in which the drain plug is opened and the bathtub water is drained. However, as the water level of the bathtub water decreases, the water pressure applied to the bathtub adapter 58 and the water heater pipe 59 decreases, so the water channel inside the water heater 57 It can be detected that the bath water is decreasing by the pressure sensor provided in the pipe. Detects decrease in bath water from ΔP (pressure) / t (time) of pressure sensor, or detects that bath water has been drained when ΔP (pressure) / t (time) no longer changes Then, it is reflected in the control flow of the sterilizing water discharge.

  It is also included in the present invention to detect the presence or absence of bathtub water drainage other than the above method. For example, a flow rate sensor may be provided in the bathtub water drainage channel (between the bathtub drain port and the bathtub water inlet of the trap body) to directly detect the presence or absence of drainage. Moreover, you may provide the electrode for bathtub water detection, and may detect bathtub water drainage by the contact presence or absence of the electrode to the water.

  FIG. 15 shows an automatic drain plug that automatically opens and closes the drain plug. The drain plug 50 is provided on the bottom surface of the bathtub 2 and the drain plug operation unit 40 is provided on the rim surface. The configuration in which both are connected by the drain plug operation transmission unit 49 is the same as FIG. 13 in which the drain plug is manually opened and closed. In this example, the drain valve automatic operation part 41 is installed under the bathtub rim surface 2a. The drain plug automatic operation unit 41 includes an electric motor 48, an output shaft 43, an engaged member 44, and a connecting shaft 45. By the operation of the electric motor 48, the connecting shaft 45 is pushed down to release the drain plug operation transmitting unit 49. Tell the drive. The engaged member 44 is provided at a joint point between the push button connection 40 b and the connection shaft 45. The drive of the release 49c is transmitted to the opening / closing of the drain plug 50 through the mechanical mechanism 52 and the drain plug support 51. The magnetic member 46 is also pushed down in conjunction with the connecting shaft 45, and the magnetic member can be moved to a position where the magnetic force can be satisfactorily detected by the position detecting means 47, so that the open / close state of the drain plug can be accurately detected.

  Automatic drain plugs can be opened and closed manually or by electric operation via a release (operation wire), so it is not necessary to manually operate the chain with the drain plug fitted into the drain port. In addition, the chain is caught on the limbs at the time of bathing and cleaning, and does not get in the way.

  FIGS. 16-21 is a flowchart which prohibits simultaneously the state in which the bathtub water is draining from the inside of a bathtub to the drain trap, and the state which is discharging the sterilizing water from the sterilizing water spouting part.

In FIG. 16, when the washing area sterilization SW is turned on, the discharge of the sterilizing water is started after detecting that the bathtub is not drained. That is, when the bathtub drainage detecting means detects that the bathtub drainage is being performed, the sterilizing water generator is not operated and the electromagnetic valve is kept closed. Then, the sterilizing water generator is not operated and the solenoid valve is kept closed until the bathtub drainage detecting means detects that the bathtub drainage is not performed. When the bathtub drainage detecting means detects that the bathtub drainage is not being performed, the sterilizing water generating device is operated, the electromagnetic valve is opened, the timer is started, and the washing area is sterilized. The presence or absence of bathtub drainage is also detected in the sterilizing water spout, and when the tub drainage is started, the sterilizing water spout is stopped. That is, when the bathtub drainage detecting means detects that the bathtub drainage has been performed, the sterilizing water generating device is stopped, the solenoid valve is closed, and the operation is terminated. When there is no bathtub drainage, the sterilizing water is sprinkled on the washing place for a predetermined time with a timer, and after a predetermined time, the sterilizing water generation and the electromagnetic valve are stopped to end 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 FIG. 17, when the washing place sterilization SW is turned on, the discharge of the sterilizing water is started after detecting that the bathtub is not drained. The presence or absence of bathtub drainage is also detected in the sterilizing water spout, and when the tub drainage is started, the sterilizing water spout is stopped. That is, when the bathtub drainage detecting means detects that the bathtub drainage has been performed, the sterilizing water generator is stopped and the solenoid valve is closed. Resets the timer at that time, the tub drained detection means, after detecting the drainage bath was over, for sprinkling predetermined time T ₀ sterilizing water washing place again, with operating the sterilizing water producing device, the solenoid valve Open the timer and start counting the timer again. As described above, before the sterilizing water is discharged, the sterilizing water is discharged again for a predetermined time T ₀ regardless of the time when the sterilizing water is discharged.

  In FIG. 18, when the washing place sterilization SW is turned on, the open / close detection means detects whether or not the bathtub drain plug is in an open state, and when the drain plug is closed, the sterilizing water is immediately discharged. When the drain plug is open, the sterilizing water starts to be discharged after the predetermined time A has elapsed. The predetermined time A is set to a time sufficient for draining the bathtub water. For example, for a 200 liter bathtub, 10 minutes or more is a standard. When the predetermined time A has passed, the bath water discharge is completed, so that the sterilizing water can be discharged to the washing place without the concern that the concentration of the sterilizing component is reduced in the drain trap.

In FIG. 19, when the washing place sterilization SW is turned on, the automatic drain plug is closed, and then water discharge of sterilized water is started. The predetermined time T ₀ sterilizing water by spraying water washing area, and ends the operation to stop the sterilizing water produced and the solenoid valve after a predetermined time.

In FIG. 20, when the washing place sterilization SW is turned on, the automatic drain plug is opened, the automatic drain plug is closed after a predetermined time T1, and then water discharge of the sterilizing water is started. The predetermined time T ₀ sterilizing water by spraying water washing area, and ends the operation to stop the sterilizing water produced and the solenoid valve after a predetermined time. The predetermined time T ₁ is set enough time to bath water is drained. By doing in this way, bathtub drainage and washing place sterilization can be performed 1 interlockingly.

FIG. 21 shows an embodiment in which the operation signal of the automatic drain plug is not accepted when the washing place sterilization SW is turned on. Is washing space sterilized SW is ON, after finishing the sterilizing water spouting the predetermined time T _0, it stops the operation of the automatic discharge valve until after time T _2.

  In addition to the above-described embodiment, the user himself / herself turns on the washing area sterilization SW and manually discharges the water in the bathtub by opening the bathtub drain plug before discharging the sterilizing water from the sterilizing water spouting section. It may be. Further, after the sterilizing water is allowed to flow into the drain trap, the tub side drain may not be drained for a while. For a while, it is 30 minutes or more, preferably 3 hours or more. For example, in order for the user to recognize this, a notification means may be provided. Here, as the notification means, for example, a means for giving a warning or notification 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 is exemplified. . In such a form, there is no need to provide a bathtub drainage detection means, an opening / closing detection means, a drain plug automatic operation section, and the like.

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.
