[0010]
DETAILED DESCRIPTION OF THE INVENTION
The heating means used in the present invention is not particularly limited as long as it can be heated to warm water necessary for performing local cleaning by heating normal temperature water, and measures capable of being heated appropriately are taken. It is possible. Specifically, it is preferable to provide a hot water tank in the middle of the water path and heat it with a heating wire in the tank.
[0011]
Although the number of washing nozzles may be different, it is preferable to use one having at least two of an anal washing nozzle 8 and a bidet washing nozzle 9 as shown in FIG. The two nozzles are preferably pivotally supported by the guide member substantially in parallel in the main body case in consideration of the installation space and the like.
[0012]
The vacuum breaker valve is preferably provided on the upstream side of the cleaning nozzle, preferably in the vicinity of the attachment portion of the flow path for allowing warm water to flow into the cleaning nozzle. The valve body of the vacuum breaking valve is a spherical ball, and the ball material is a hard material such as a resin, stainless steel or other corrosion resistant metal or glass, or an elastic body such as rubber made of NBR, EPDM or silicon. Can be used. Further, the same material as the above-described ball material can be used for the seal portion with which the valve body abuts at the time of local body part cleaning.
[0013]
The drainage groove is provided below the air communication portion of the vacuum breaker valve. Since the cleaning nozzle expands and contracts, the intake port naturally moves. Therefore, the drainage groove is provided from the rear end to the front end of the guide member for expanding and contracting the cleaning nozzle, so that drainage can be received in any part from the storage position of the cleaning nozzle to the maximum extension position. Yes.
[0014]
The front wall portion used in the present invention is provided with a drainage groove fitting hole for passing through a hole through which the cleaning nozzle passes and a drainage groove for flowing water leaked from the intake drainage port. When self-cleaning, etc., water is provided so that water will not be inadvertently scattered. The drainage groove described above is provided so as to protrude from the drainage groove fitting hole provided in the front wall portion, so that the drainage can be reliably performed outside the apparatus.
[0015]
【Example】
Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a partially enlarged view of the vicinity of the cleaning nozzle, in which the anal cleaning nozzle 8 and the bidet cleaning nozzle 9 are attached to the guide member 10 so as to be parallel. The anus cleaning nozzle 8 and the bidet cleaning nozzle 9 are adapted to be expanded and contracted in the vertical direction in the drawing to clean the local body part, and at one end thereof, a jet outlet 11 for jetting cleaning water is provided, A vacuum breaker valve 12 is installed at the other end. Further, there is a drainage groove 13 attached in the longitudinal direction of the guide member 10 between the anal washing nozzle 8 and the bidet washing nozzle 9, and the suction port of the vacuum breaker valve 12 passes through the upper part of the drainage groove 13. It is like that.
[0016]
The guide member 10 is provided with a front wall portion 14 in addition to the drainage groove 13 described above, and water from the distal end side (the jet outlet 11 side) of the anus cleaning nozzle 8 and the bidet cleaning nozzle 9 is more than that. I try not to get into the back. This is because the washing water used when performing self-cleaning with the hot water ejected from the ejection port 11 in the vicinity of the ejection port 11 is not carelessly scattered. As shown in FIG. 3, the front wall portion 14 is provided with an anus washing nozzle passage hole 15, a bidet washing nozzle passage hole 16 and a drain groove passage hole 17, and the anal washing nozzle 8 and the bidet washing nozzle 9 are expanded and contracted. The drainage from the drainage groove 13 is also allowed to pass therethrough.
[0017]
The vacuum breaker valve 12 will be described with reference to FIG. 4, which is a cross-sectional view of the AA portion shown in FIG. 2. The vacuum breaker valve 12 provided in the anal washing nozzle 8 and the bidet washing nozzle 9 is a valve body 18. In the normal operation, the valve element 18 is pressed against the seal portion 19 by the water pressure of the washing water at the time of local cleaning, and the hot water does not leak from the intake port 20 and the local cleaning is completed. When the water pressure is applied to the valve body 18, the valve body 18 is separated from the seal portion 19 due to the atmospheric pressure, and air enters the anal cleaning nozzle 8 and the bidet cleaning nozzle 9 to replace the hot water with air.
[0018]
If for some reason, the adhesion between the valve body 18 and the seal portion 19 is impaired, hot water leaks from the intake port 20 during local cleaning, but the drainage groove 13 is provided below the intake port 20. However, the leaked hot water passes through the drainage groove 13, passes through the front wall portion 14, and is discharged outside the apparatus.
[0019]
【The invention's effect】
In the present invention, even if water leaks from the vacuum breaker valve, there is no danger of leakage because it is discharged to the outside of the apparatus through the drainage groove provided in the guide member. Further, since the drainage grooves are provided corresponding to the movement path of the vacuum breaker valve, it is possible to reliably discharge the hot water leaking out of the apparatus regardless of the position of the cleaning nozzle. Even in the case of a human body local cleaning apparatus having a plurality of cleaning nozzles, an increase in the number of parts can be suppressed by sharing the drainage groove, and the cost increase can be minimized. And it becomes possible to discharge to the exterior of an apparatus reliably by making a drainage groove protrude from a front wall part.
