[Problem to be Solved by the Invention] In the above-mentioned conventional hot water cleaning apparatus, immediately after the start of cleaning, the water remains in the mixing valve 7 and the pipe 7a, and therefore, the target mixed water temperature of the mixing valve 7 Water of lower temperature is supplied to the shower nozzle 10 and the charm nozzle 11. As a result, low-temperature water is applied to the buttocks of the toilet user, which is surprising to the user and inferior in feeling. (Hereinafter, such low-temperature water generated in the initial stage of washing may be referred to as initial low-temperature water.) As a countermeasure, when the temperature of the residual water in the mixing valve 7 or the pipe 7a is low when the user sits on the toilet seat, this low-temperature water is used. To the toilet bowl. However, in a case where the initial low-temperature water is discharged to the toilet bowl in this way, there is a risk that water splashing in the toilet bowl may hit the user. In addition, since water circulation starts just by the user sitting,
The user may misunderstand that some trouble has occurred in the hot water cleaning device. Furthermore, the end of the discharge pipe faces the toilet bowl in order to allow the low-temperature water to flow into the toilet bowl, but urine and bounced water hang on the end of the discharge pipe and flow backward or diffuse into the discharge pipe. May cause internal contamination.

[Means for Solving the Problems] The hot water washing device of the present invention is connected to a washing nozzle for jetting hot water toward the buttocks of a seated occupant of a toilet bowl, and is connected to the washing nozzle via a supply flow path. And a mixing valve for supplying mixed water at a predetermined temperature by mixing water and water, and the water in the supply flow path is branched to a drain port or a drain pipe provided at a location other than the toilet. A branch channel that leads directly,
Seated person detecting means for detecting a seated person on the toilet seat, and when the water temperature in the supply flow path is lower than a predetermined temperature when the seated person detection means detects a seated person, water in the supply flow path is A flow path switching device that flows through the branch flow path.

[Action] In the hot water washing apparatus of the present invention, when the mixed water from the mixing valve is low in temperature when a person sits on the toilet seat, the low-temperature water is discharged from the branch flow path to a drain provided in a portion other than the toilet. Discarded directly into mouth or drain. When the mixed water from the mixing valve is higher than the predetermined temperature, the mixed water is supplied to the washing nozzle in accordance with the operation of the device by the toilet user.

In this way, since the initial low-temperature water is directly discharged to the drain port or the drain pipe provided in a place other than the toilet, and not discharged to the toilet bowl, splashing water is applied to the toilet user or the toilet user is damaged. There is no misunderstanding.

Embodiment An embodiment will be described below with reference to the drawings.

FIG. 1 is a system diagram showing a configuration of a hot water cleaning device according to an embodiment of the present invention, and FIG. 2 is a longitudinal sectional view of a toilet room having a toilet incorporating the hot water cleaning device.

As shown in the figure, a two-way valve 26 composed of an electromagnetic valve is provided in the middle of a pipe 7a connected to the tap of the mixing valve 7. A chamber 27 is provided downstream of the two-way valve 26, and a water temperature sensor 28 is provided in the chamber 27. Pipes 29 and 30 are drawn out of the chamber 27, and the pipe 29 branches into pipes 8 and 9 from the middle thereof.
The pipe 30 has a distal end opening in a drain port 60 in a toilet room (in this embodiment, a trap 62 in a drain groove 61 of a bathroom with a toilet). A two-way valve 32 composed of an electromagnetic valve is provided in the middle of the pipe 30.

The two-way valve 26 is driven to open and close by a seat switch 34 of a toilet seat 33. Further, the two-way valve 32 is opened and closed by a relay 35 operated by a detection signal of the water temperature sensor 28.

In FIG. 2, the toilet 31 is attached to a counter 36 in the toilet room, and the hot water supply pipe 1 and the water supply pipe 2 are provided.
Is passed through the counter 36. A toilet seat box 37 is provided on the upper surface of the toilet 31, and the toilet seat box 37 is provided.
The strainers 3 and 4, the mixing valve 7, the two-way valves 26 and 32, the shower operation valve 12, the charm operation valve 13, and the like are installed therein. The operation handles 12a and 13a of the valves 12 and 13 are provided so as to protrude from the outer surface of the toilet seat box 37. Further, the shower nozzle 10 and the charm nozzle 11 are attached to a rear surface portion of the toilet bowl 32.

Reference numeral 38 in FIG. 2 indicates a toilet lid, and reference numeral 39 indicates a trap unit. Although not shown, another water supply pipe is connected to the toilet 31 to enable the supply of flush water to the rim water passage 40 of the toilet 31. A drain pipe (not shown) is connected to a drain port 41 of the toilet bowl 31. A trap 62 is provided at a drain port 60 of the waterproof pan 61.

The other reference numerals in FIG. 1 indicate the same parts as those shown in FIG.

The seat switch 34 is a toilet seat in the toilet box 37.
33 on the pivot hinge part or the toilet seat 33
Is provided on the lower surface of.

In the hot water washing apparatus thus configured, the toilet 31
When the user sits on the toilet seat 33, the seat switch 34 is turned on, and the two-way valve 26 is opened. Thereby, hot water and water from the hot water supply pipe 1 and the water supply pipe 2 flow into the mixing valve 7, and the mixed water flows into the chamber 27 through the pipe 7a. Note that the two-way valve 32 is in an open state in this initial state. When the temperature of the mixed water detected by the sensor 28 is lower than a predetermined temperature (for example, 35 ° C.), the relay 35 does not operate the two-way valve 32 to close, and this open state continues. Therefore, the low-temperature mixed water from the mixing valve 7 is
It is discarded from 30 into the drain 60.

The temperature of the mixed water gradually rises to a predetermined temperature (for example, 35
C.), the relay 35 closes the two-way valve 32. Then, the water pressure of the mixed water is applied to the nozzles 10 and 11. Therefore, in this state, the shower nozzle 10 or the charm nozzle 11 is opened by opening the shower operation valve 12 or the charm operation valve 13.
Warm water is spouted from The operations of the shower nozzle 10 and the charm nozzle 11 associated with the opening and closing operations of the operation valves 12 and 13 are the same as those in the conventional example shown in FIG.

As described above, in the present embodiment, the low-temperature water remaining in the mixing valve 7 and the pipe 7a is discharged from the shower nozzle.
10. Since it is not supplied to the charm nozzle 11, the mixed water at an appropriate temperature is jetted toward the buttocks of the human body immediately after the start of the washing. Moreover, in this embodiment, since the initial low-temperature water is directly discharged to the drain port 60, there is no danger that the water will bounce back in the toilet bowl or that the toilet user will mistakenly regard it as a failure. In addition, in this embodiment, since the tip of the pipe 30 faces the drain port 60 in the counter 36, the outflow of the initial low-temperature water is not visually recognized by the toilet user at all. For this reason, erroneous recognition by visually checking the outflow of the initial low-temperature water (thinking that the hot water cleaning device has failed or malfunctioned) is reliably prevented. Of course, the appearance is very good because the discharge pipe 30 is not visible.

The water remaining in the pipes 29, 8, 9 and the nozzles 10, 11 is jetted toward the buttocks of the human body immediately after the start of washing.
However, the amount of water remaining in these pipes and nozzles is extremely small, and after the remaining water is supplied with mixed water at an appropriate temperature, the amount of low-temperature water poured into the buttocks of the human body is extremely small. The time taken is very short. Therefore, according to this embodiment, only the mixed water having a substantially appropriate temperature can be poured onto the human hips immediately after the start of the cleaning, and extremely comfortable hip cleaning can be performed.

In the embodiment shown in FIG. 1, the pipe 29 is drawn out of the chamber 27, and the pipe 29 is branched into the pipes 8, 9, but in the present invention, the pipes 8, 9 are directly connected to the chamber 27. You may do it. In the present invention, the sensor 28
The attached chamber 27 may be disposed upstream of the two-way valve 26. However, when the chamber 27 is disposed downstream of the two-way valve 26 as shown in FIG. 1, the pipes extending from the chamber 27 to the nozzles 10 and 11 are shortened, and the water remaining in the pipes is reduced accordingly. Is chosen.

FIG. 3 is a system diagram of a hot water washing apparatus according to another embodiment of the present invention. In the present embodiment, a chamber 27 with a sensor 28 is installed in the pipe 7a, and a three-way valve 42 composed of an electromagnetic valve is installed downstream of the chamber 27. The detection signal of the water temperature sensor 28 installed in the chamber 27 and the detection signal of the seat switch 34 are input to a relay 43, and the control signal from the relay 43 switches the flow path of the three-way valve 42.

In the embodiment of FIG. 3, when no person is seated on the toilet seat, the seat switch 34 is off, and the three-way valve 42 is connected to the pipe 7a and the pipe 29 regardless of the detection signal of the water temperature sensor 28. , 30 are blocked. Therefore,
The outflow of the mixed water from the mixing valve 27 is stopped.

When a person sits on the toilet seat, the seat switch 34 is turned on. Then, according to the temperature detected by the water temperature sensor 28, the three-way valve 42
The pipe 7a is communicated with one of the pipes 29 and 30. In a normal case, the temperature of the residual water in the chamber 27 is lower than a predetermined temperature, and the three-way valve 42 connects the pipe 7a to the pipe 30. Thereby, low-temperature residual water in the chamber 27, the pipe 7a, and the mixing valve 7 is discarded from the pipe 30 to the drain port 60. When the temperature detected by the water temperature sensor 28 exceeds a predetermined temperature, the three-way valve 42 connects the pipe 7a to the pipe 29, and the nozzle 1
It becomes possible to supply the mixed water to 0 and 11. In this state, the buttock washing operation by the shower nozzle 10 and the charm nozzle 11 is performed by operating the operation valves 12 and 13. Nozzle 1 for opening and closing operation valves 12 and 13
The operations of 0 and 11 are the same as in the conventional example of FIG.

The embodiment of FIG. 3 also discharges the initial low-temperature water directly to the drain. Of course, immediately after the start of the buttocks washing, a suitable temperature of hot water can be poured into the buttocks, so that a very comfortable buttocks washing can be performed.

FIG. 5 shows still another embodiment, in which a temperature sensing valve 50 is provided at a branch portion between the pipe 7a and the pipes 29 and 30. This temperature sensing valve has a built-in temperature sensing valve body that expands and contracts according to the water temperature.
The pipes 7a and 29 are connected when the water temperature is higher than a predetermined temperature. Other configurations are the same as those in FIG. According to this embodiment, too, the initial low-temperature water is directly discharged to the drain port 60.

6 and 7 are an internal front view and a plan view of a unit bath room 70 having a toilet incorporating the device of the present invention. A bathtub 71, a toilet bowl 72, a counter 73, a washbasin 74, and the like are installed in the unit bath toilet room 70, and a toilet seat box type hot water washing device 75 is installed on an upper surface of the toilet bowl 72. 76 is a water pipe, 77 is a hot water pipe, 78
Indicates a power cord. Front panel 73 of this counter 73
A drain port 80 is provided in the waterproof pan 79 at a position deeper than a, and a drain trap 81 is attached to the drain port 80. The end of a pipe (not shown) for discharging the initial low-temperature water extending from the hot water washing device 75 faces the drain port 80, and is configured to discharge the initial low-temperature water directly to the drain port 80. .

Of course, FIGS. 6 and 7 are examples of the present invention, and it is clear that the present invention can be applied to a unit bath and toilet room other than the illustrated one.

In the above embodiment, the initial low-temperature water is discharged to the drain (drain), but may be discharged to the drain pipe.

[Effects] As described above, according to the hot water cleaning device of the present invention, mixed water at an appropriate temperature is squirted toward the buttocks of a human body immediately after the start of washing, and extremely comfortable buttocks washing can be performed. . In addition, since the initial low-temperature water is directly discharged to drains or drain pipes provided in places other than the toilet, and not discharged to the toilet bowl, bounce water is applied to the toilet user or the toilet user is mistaken as a malfunction. Nothing to do. further,
Since there is no discharge pipe for discharging the initial cold water into the toilet bowl,
Urine and bounce water do not fall on the discharge pipe,
Urine and rebound water do not flow back or diffuse into the discharge pipe to contaminate it.
