Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device for washing human body parts with warm water or the like.

[0002]

2. Description of the Related Art A conventional sanitary washing device of this type is constructed as shown in FIG. Reference numeral 31 is a water supply pipe to the low tank of the toilet bowl, and wash water to which tap water pressure is applied is branched from this water supply pipe 31 via a joint 32 and is supplied to the wash circuit. Three
A water shutoff valve 3 is attached to the joint 32 and stops or controls water flow to the washing circuit. From the water shutoff valve 33, a strainer 34 of the apparatus main body, a solenoid valve 35 serving as a water supply valve, Flow rate control valve 36, hot water tank 37, vacuum break valve 3
8 and the like are fluidly connected in series, and a nozzle 39 for cleaning the anus is attached to the extreme end.

In this configuration, when the user performs a washing operation, the solenoid valve 35 is energized to open the valve body, and the water pressure is transmitted backward, so that the hot water warmed in the hot water tank 37 is ejected from the nozzle 39. And is used for cleaning the anus.
Since the cleaning flow rate can be controlled by the flow rate control valve 36, the amount of hot water that meets the user's preference can be obtained.

[0004]

However, in such a structure, when the anus is washed, the washing mess is applied to the nozzle 39, so that the urine may reach the nozzle 39 during male urine.
Ri is a non-hygienic.

The present invention solves the above-mentioned conventional problems, and provides a sanitary washing device which cleans the washing nozzle and hygienically performs local washing.

[0006]

The technical means of the present invention for solving the above problems is to provide a water supply valve connected to a water source,
A flow rate control valve, a nozzle, and a nozzle cleaning means for cleaning this nozzle are provided, and the water supply valve is opened by a cleaning operation,
The nozzle is cleaned by the nozzle cleaning means, and then the cleaned nozzle is used for local cleaning.

[0007]

The function of this technical means is as follows.

Namely, since the nozzle is cleaned by opening the water supply valve <br/> nozzle cleaning unit by washing, the nozzles of the human private cleaning becomes clean and that thereafter performing hygienic part washing with this nozzle Comes out.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Figure 2 shows the appearance of the sanitary washing device.
This sanitary washing device is composed of a toilet seat 1 and a storage body 3 fixed to the toilet body 2 and containing a washing device and the like. A user sits on the toilet seat 1 and, after defecation, an anus with hot water sprayed from a nozzle 4 Clean the parts.

FIG. 1 shows a water circuit of a cleaning device. A water shutoff valve 5 connected to a water source, a strainer 6, a solenoid valve 7 serving as a water feed valve, a flow control valve 8, a check valve 9, The warm water tank 10, the vacuum breaker valve (vacuum breaker) 11 and the nozzle 4 constitute a main washing water channel. In addition to the main washing water channel, a branch is made between the solenoid valve 7 and the flow rate control valve 8, and the throttle 12 and the vacuum break valve (vacuum breaker).
A discharge port 14 is provided in the vicinity of the nozzle 4 by connecting 13 and an auxiliary water channel which is a nozzle cleaning means for cleaning the nozzle 4 with the discharge water from the discharge port 14 is provided. The throttle 12 in this auxiliary water passage is not necessary if the pipe is thin.

In this structure, when the user performs a washing operation, the solenoid valve 7 is opened, water is discharged from the discharge port 14 through the auxiliary water passage to wash the nozzle 4, and the dirty water attached to the nozzle 4 is washed away. ,To clean. When the user opens the flow rate control valve 8, water pressure is also applied to the warm water tank 10, and the warm water warmed by the heater 15 is ejected from the clean nozzle 4 to sanitarily clean the anus or the like. Perform cleaning. In the case of men's urine, etc., urine is often scattered and pollutes the nozzle 4, but sewage and the like adhering to the nozzle 4 is also washed away immediately before local cleaning, so extremely clean local cleaning can be performed. .

[0012]

As described above, the present invention is provided with a water supply valve, a flow rate control valve, a nozzle, and nozzle cleaning means for cleaning the nozzle, which is connected to a water supply source, and opens the water supply valve by a cleaning operation. Nozzle cleaning means is used to clean the nozzle, and the cleaned nozzle is used to perform local cleaning, so that the dirty water that has been scattered and adhered to the nozzle during men's urine, etc., is washed away for hygienic local cleaning. Things come out.
