Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary washing apparatus such as a toilet or bidet for washing a part to be washed after stool.

[0002]

2. Description of the Related Art Japanese Patent Publication No. 61-45737 discloses a sanitary washing apparatus which discharges flush water to the toilet at the beginning of flush water discharge, discharges cold accumulated water and cleans a nozzle. I have.

[0003]

However, in the case of the cleaning nozzle having a plurality of ejection ports, the one disclosed in the above publication discloses a nozzle having a plurality of ejection ports to perform nozzle cleaning and buttocks cleaning from the same ejection hole. Although the water after the nozzle cleaning may enter, the jetting port is not used thereafter, so that the calcium component contained in the cleaning water solidifies and the jetting port may be clogged. For this reason, in a washing nozzle provided with a plurality of ejection ports, washing water is simultaneously discharged from the plurality of ejection ports to the toilet side at the initial stage of discharge of the washing water. However, since the washing water is discharged from a plurality of jets at the same time, the discharge amount is considerably large, and much of the hot water heated by the water heater has to be discarded. The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a sanitary washing device that can wash a washing nozzle with a relatively small amount of water in an initial stage of washing water discharge in a washing nozzle having a plurality of ejection holes. To provide.

[0004]

In order to achieve the above object, a cleaning nozzle for discharging cleaning water to a part to be cleaned by a user, and a plurality of nozzles provided in the cleaning nozzle are provided. An outlet, cleaning water selective supply means for selectively supplying cleaning water to the spout, and at least one of the plurality of spouts
Selection operation means for selecting one, and control means for controlling the washing water selection and supply means to discharge washing water to the toilet side from a spout not selected in the initial stage of washing water discharge by operating the operation means. Since nozzle cleaning is performed from a spout different from the spout used for washing the human body, even if water after nozzle washing enters the used spout, it can be immediately discharged and the spout However, there is no fear that it will be clogged with chalk.

According to a second aspect, in the first aspect, a plurality of ejection ports are provided in one cleaning nozzle and can be used for different purposes, so that the nozzle device can be reduced in size.

Further, in the sanitary washing device according to the first and second aspects, a vacuum breaker is provided in a flow path from a water supply source to the washing nozzle, so that accumulated water remains in the washing nozzle after use. This can be reliably prevented.

Further, in the sanitary washing apparatus according to the third aspect, the vacuum breaker is provided downstream of the washing water selecting and supplying means, so that the inside of each flow path after use is reliably brought to the atmospheric pressure. And the structure of the cleaning water selective supply means can be simplified.

According to a fifth aspect of the present invention, in the sanitary washing apparatus according to the third aspect, the washing water selecting and supplying means comprises a washing water supplying means and a washing water selecting means. By providing the vacuum breaker between the selector and the selection means, the number of the vacuum breakers can be reduced to one, and the configuration can be simplified.
