In general, the flow path configuration of the electric bidet is a pressure reducing valve 32 for reducing the water pressure of the water supply (30) to a suitable water pressure (0.8 ~ 1.4 Kgf / Cm2) to be used in the electric bidet, as shown in Figure 3 and supplied into the electric bidet In the case of the instant hot water bidet, the flow meter 34 for detecting the flow rate of the tap water 30 flowing into the electric bidet or the water tank 38 for storing and warming the washing water of the tap water 30 in the case of the low temperature bidet Passing through this, the anal cleaning nozzle 46, the female local cleaning through the flow path switching valve 40 that determines the flow path to selectively supply the water of washing water, anal washing, female local washing, or nozzle washing. The nozzle 44 and the nozzle cleaning nozzle 42 are provided, and after this, the tap water is configured to clean the user's anus or the female part and the nozzle.

At this time, the solenoid valve is configured between the flow path switching valve 40 and the anal cleaning nozzle 46.

When the solenoid valve of the prior art is mounted in the comfort solenoid valve position of FIG. 3, when the solenoid valve enters the inlet port 22 of the comfort valve solenoid valve through the flow path switching valve 40 and exits to the outlet port 21, the flow path is orifice 26 wall. After hitting, it flows to the upper side and then to the lower side, and then the flow path turns to the right once again and exits in the exit direction.

As the flow path is complicated as described above, when the solenoid valve is shut off for a short time and then opened again, the water pressure that has risen momentarily is not delivered to the anal cleaning nozzle and decreases when it is shut off.

delete

delete

For this reason, the problem of the next subject which this invention wants to achieve was not solved.

First, when the solenoid valve is momentarily shut off, the water pressure rises high and the water pressure must be sprayed as it is to clean the anus. As described above, in the conventional solenoid valve, the constant water pressure flowing into the electric bidet is lost. Can't expect

Therefore, the problem to be achieved in the present invention could not be solved.

The present invention is configured to always open the solenoid valve in order to improve such a conventional problem when the power is not applied to the comfort valve solenoid valve is always the gate valve solenoid valve is open so that the washing water can flow, the comfort valve solenoid valve body The part forms a through-hole without interference in the washing water flow, so that there is no loss of water pressure, and when the power is applied to the comfort valve solenoid valve, the water pressure of the inlet side is instantaneously increased, and the anal cleaning nozzle is discharged through the water outlet at the increased water pressure. The washing water flows into the furnace to spray the water pressure to the user as it is.
