Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing device provided with a washing nozzle for washing a washing portion of a human body with discharged washing water.

[0002]

2. Description of the Related Art Conventionally, in a sanitary washing apparatus provided with a washing nozzle for washing a washing portion of a human body with discharged washing water, water supply to the apparatus body is roughly classified into a low tank installed near the toilet body. There is a pump water supply method of supplying the stored water by a pump and a water supply direct connection method of supplying water via a water supply pipe directly connected to the water supply pipe. In the latter method of directly connecting to the water supply, the water supply method restricts the amount of water supply in the water supply pipe, and the apparatus main body is supplied with water in excess of the amount used for cleaning. For this reason, the sanitary washing device installed by adopting the direct water supply connection system is provided with a water supply / drainage structure for discharging excessively supplied excess water into the toilet body as waste water. As shown in FIG. 23, a conventional drainage water discharger as a conventional water drainage structure has a tip of a drainage hose 22 led out from a reserve tank 21 integrally provided as a drainage portion 20 on the bottom surface of the main body case 5a. The structure is that it is inserted and connected to the end of the case 40, and the wastewater flowing out into the case 40 flows along the water supply flow path surface in the case 40 and is discharged into the toilet body from the waste port provided at the front end. ing. Regarding the flow of waste water to this waste water discharge device, first, the valve body 16 such as a solenoid valve is opened, the primary side of the water supply is passed through the water supply port, and the city water is supplied from the water pipe into the reserve tank 21. From this, the cleaning water is pumped up by the pump 17, and the cleaning water is ejected from the cleaning nozzle 13 through the hot water storage tank 14.
At this time, the water supplied from the primary side of the water supply to the water supply port has a primary pressure of 0.
Be varied up to ^{5kg / cm 2 ~7.5kg / cm 2} ,
The amount of water supplied to the reserve tank 21 is 1.3 liters / min.
Although it is kept within the range of 2.2 liters / minute, the maximum amount of washing water is 1 because the user can select the amount of washing water in the range of 0.6 liters / minute to 1.1 liters / minute. ．
6 liter / min of water is discharged as overflow water from the drain hose 22 through the case 40 into the toilet body through the drain port of the case 40. In addition, this drainage hose 22
Also functions as a vacuum breaker, and prevents the dirty water in the toilet body from flowing back to the primary side from the cleaning nozzle 13 or the like if the primary side of the water supply becomes negative pressure.

[0003]

However, in the conventional example as described above, when connecting the drainage hose 22 to the case 40, the tip of the drainage hose 22 is integrally provided on the bottom surface of the main body case 5a. It is designed to be directly inserted and connected to the end of the case 40, and it is difficult to insert the tip of the drainage hose 22 having elasticity in a narrow place in the device body 5 into the end of the case 40. There is a problem that the workability when connecting the drainage hose 22 is poor and it takes time to assemble, and in order to form the shape of the part sandwiching the drainage hose 22, rubbing the mold core and the cabinet There are various problems such as the need for a structure and a complicated mold structure.
