Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a hot water tank of a human body local cleaning apparatus, and more particularly to the temperature distribution of the wash water in the hot water tank.

(Prior Art) Conventionally, in this type, in order to equalize the temperature distribution of the wash water in the hot water tank, there is known a technology in which a perforated plate is provided at the bottom of the tank to form a rectifying chamber. (Actual development 60-5387
4) (Problems to be solved by the invention) However, the small holes of the perforated plate in the above technique are merely those which vertically penetrate the flat plate. Therefore, the supply cold water rectified in the lower part of the perforated plate has a water force in the direct upward direction, and is mixed with the hot water in the upper part which has already been heated, causing a decrease in the temperature of the hot water. In order to make up for this drawback, there were some cases in which a partition plate was provided in addition to the perforated plate, but there was a problem in that a satisfactory temperature distribution could be obtained in any case due to the difficulty of the construction cost. The present invention aims to solve such a drawback.

[Constitution of device]

(Means for Solving the Problems) In the present invention, the following means were taken to solve the above problems. That is, a perforated plate is provided at the bottom of the hot water tank to form a straightening chamber, and cold water is prevented from flowing out directly upward from the small holes of the perforated plate. Was molded.

(Operation) As a result, the cold water temporarily blocks the upward flow at the wall of the small hole that is integrated with the perforated plate, and tends to flow out laterally from the gap formed between the cold water and the wall.

This leads to the latter effect, but the cold water spreads over the entire bottom of the hot water tank and acts to push up the hot water as a whole.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is an overall (group) view of a hot water tank equipped with the device of the present invention, which shows one equipped with both nozzles for anus and bidet, both of which have the same structure and operation, so that one side Only mention.

In FIG. 1, 1 is a hot water tank, 2 is a water supply port, and 3 is a vacuum breaker.

The water is supplied from the above-mentioned route, through the cold water channel 4 and the cold water inflow port 5, and below the perforated plate 6 provided at the bottom of the hot water tank 1.
That is, it flows into the rectification chamber 7.

This inflow water is the perforated plate 6 shown in detail in FIGS.
It flows out into the warm water tank 1 through a large number of small holes 6a, 6a 'provided in the. As can be seen from FIG. 3, the small holes are
Walls 6b and 6b 'and skimmers 6c and 6 are integrally formed on 6a and 6a'.
c ′ etc. are formed.

Therefore, the outflow water from the small holes hits the walls 6b, 6b 'and the like, flows out from the front and rear or left and right gaps 6c, 6c' and spreads to the bottom of the hot water tank. Then, the warm water already heated by the heater 8 is entirely pushed up.

The warm water pushed up passes through the warm water passage 9 from the warm water discharge port 9a, and the nozzle 11 is advanced through the electromagnetic valve portion 10 when the operation switch is turned on. Then, the warm cleaning water is ejected from the ejection port 11a at the tip at a predetermined position.

Needless to say, the wall of the perforated plate may be a separate structure instead of being integrated.

[Effect of device]

In order to suppress the outflow degree of cold water to the upper side of the hot water tank, it is sufficient to reduce the small holes of the perforated plate even in the conventional technique, but the flow resistance increases, and the cleaning jet output to the human body becomes weaker.
If the supply water pressure is low, the detergency will decrease.

In the present invention, if the gaps formed by the perforated plate and the wall formed integrally with each other are arranged in the front-rear direction or in the left-right direction, the spread of the cold water to the bottom of the tank becomes more effective. I can do things.
