Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot water tank of a human body private parts cleaning device (hereinafter simply referred to as a cleaning device) in a toilet.

As flush toilets have become popular in recent years, the convenience of installing post-use cleaning devices is also increasing. In a hot water cleaning device that uses hot water, it is preferable to introduce the supply water as a pressurized source directly to the bottom of the tank and to supply the hot water from the top of the tank to the nozzle, since this allows the temperature of the cleaning water to be maintained.

However, in a tank equipped with an over-seven pipe for cleaning the nozzle itself during cleaning and discharging the water discharged when the nozzle is stored, extending the inflow pipe to the bottom of the tank may cause a siphon phenomenon when draining. This causes the inconvenience of draining the water inside the tank. Therefore, in conventional tanks of this type, it has not been possible to extend the inflow pipe to the bottom of the tank, although this is known to be a good idea in terms of maintaining the water temperature. The present invention aims to eliminate this defect.

Embodiments of the present invention will be described below based on the drawings.

1 is a tank equipped with a water temperature heating device (not shown); 2 is a water supply port thereof; 8 is an inflow pipe that communicates with the water supply port 2 and has one end hanging downward near the bottom of the tank;

The tank 1 has a nozzle inflow pipe 4 for cleaning water.
Nozzle support 5 is fixed 7! nru.

Reference numeral 6 denotes a nozzle, which has a distal end ka and several ejection ports 6a, and is housed in the nozzle support 5 so as to be slidable in the front and back directions and always biased in the direction of arrow A through a spring 7.

Reference numeral 8 denotes a valve body, which connects or blocks the inside of the nozzle inflow pipe 4 and the inner hole 6b of the nozzle 6, and is normally in a closed state by a spring 9y as shown in the figure.

10 is a vacuum breaker, which is constructed integrally with the tank 1 on the water supply port 2 and the inlet pipe δ of the tank, and a valve 11 is arranged &2! nru.

Reference numeral 12 denotes an overflow pipe, one end of which communicates with the vacuum breaker through a small hole xoat- in the vacuum breaker, and the other end opening T near the top of the exposed tip when the nozzle 6 is stored.

The hot water tank of the present invention has the above-mentioned configuration, and its operation, effects and effects will be described below.

When the cleaning device is used, the water pressure flowing from the water supply port causes the valve 11 to rise and close the vacuum breaker 10 (T
Ru. Therefore, a part of the inflow water flows out onto the nozzle 6 through the small hole 10ak and the overpipe 70 to clean the nozzle area.

On the other hand, the excess water is sent to the bottom of the tank 1 through the inflow pipe 8, and the hot water in the upper part that is pressurized in the n1 tank flows into the nozzle inflow pipe 4 and flows through the 6 nozzles n1, and the valve body 8 is pressed at the appropriate position. When opened, warm water is spouted from the spout to perform desired local cleaning.

This water supply is different from the case where the inlet and outlet are provided at the top of the tank as in the conventional type, but is supplied to the bottom of the tank, so the hot water from the top is gradually led to the nozzle, and the cold water is directly flowed to the nozzle. After stopping the water supply (when not in use), store the nozzle 11 in its original position.
, the water discharged from the nozzle support is discharged from the overflow pipe 70 or the inflow pipe 8 and the overflow pipe 12.
is cut off by an air layer using a vacuum breaker.
Therefore, siphon phenomenon does not occur. Therefore, there is a risk that it will flow out from the tank's hydraulic overflow pipe.
It's not my strength.

As you can see from the above explanation, the main @Q hot water tank (
In this case, the temperature of the water supplied to the nozzle is maintained well. Therefore, the user is comfortable and does not feel any discomfort, and at the same time, the washing water in the tank can be prevented from flowing out due to the siphon effect, and the usage condition can be maintained to satisfy the constant washing device.
