Description

[Detailed Description of the Invention] [Subject of the Invention] This invention relates to a hot water tank for a human body private part cleaning device (hereinafter simply referred to as a cleaning device), and particularly relates to the temperature distribution of the cleaning water.

[Prior art]

For hot water cleaning equipment that supplies tap water to a hot water storage tank and uses the supply pressure to guide the hot water to the cleaning nozzle, the conventional tank is As for the form, as shown by the symbol A in FIG. 1, a vertically elongated one was often adopted. Due to its structure, the tank was generally placed on the rear side of the toilet seat B (Japanese Patent Laid-Open No. 72540/1983).

[Problems with conventional technology and their technical analysis]

Due to its structure, a vertical tank must be installed behind the toilet seat, which naturally occupies a large amount of space in the left and right directions. In recent years, in view of housing conditions, the space occupied by toilet cleaning devices has become a problem, and devices that occupy less horizontal space have been required.
In addition, there is a need for increased tank capacity, so the idea of a horizontal tank has emerged to meet the demand for better placement.

Vertical tanks are suitable for maintaining uniform temperature distribution due to their shape, but in the case of horizontal tanks (horizontally long), the temperature will rise partially near the heater, and even if the thermostat is turned off, the temperature will rise in areas far from the heater or thermostat. The drawback is that the temperature distribution is low and the overall heat capacity is low.

[Technical issues]

The purpose of this application is to improve the temperature distribution in a horizontal tank.

[Technical means]

In the present invention, the above problem was solved by the following means. That is, a heater is provided in the lower part of the tank and a thermostat is provided in the upper part, and a partition plate is arranged between the two so as to cut off the heater and the thermostat, and between the two, there is a This prevents direct convection from occurring.

[Effect of technical means]

With the above configuration, although the cold water at the bottom of the tank is heated by the heater, the partition plate prevents highly heated water near the heater from flowing directly toward the thermostat. This heating-induced short-circuit prevention of convection leads to the effects described in the next column.

[Special effects produced by the present invention]

As already mentioned in the problem section of the horizontal tank, due to its form, the distance in the left and right longitudinal directions is larger than the vertical distance between the heater and thermostat. For this reason,
At the time the thermostat senses the temperature, there tends to be a difference in temperature between that part and other parts. In this invention,
This tendency occurs because the convection short-circuit is broken by the partition plate, and the accompanying thermostat heats up the entire interior of the tank. Then, hot water with uniform temperature distribution can be supplied to the nozzle side at all times.

〔Example〕

1 is a hot water tank, and a vacuum breaker 2 is attached on top of the hot water tank 1.

3 is a water supply pipe whose upper part opens to the upper part of the tank 1 and is sealed and fixed with a seal member 4.

Reference numeral 5 denotes a rectifying plate fixed to form a space 6 over the entire inner bottom of the tank 1, and has one inlet 5a and numerous small holes 5b provided throughout. Then,
The lower outlet of the water supply pipe 3 is connected to the inlet 5 of the current plate 5 via an elastic seal member 7 having a lip portion.
It is pressed against a. 8 is a connection pipe from a water pressure source, and 9 is a discharge port of the vacuum breaker 2.

Reference numeral 10 denotes a heater, which is provided in the lower part of the tank, that is, in the vicinity directly above the rectifying plate 5, and 11 is a thermostat, which is arranged in the upper part of the tank.

The hot water tank 1 shown in this embodiment is partially formed with rising enlarged portions 1a in order to increase the amount of hot water stored. Reference numeral 12 denotes a partition plate which is the gist of the present application, and is installed between the heater 10 and the thermostat 11, covers the rising enlarged portion 1a from below, and its tip extends below the rising wall 1b. In addition, as shown in the figure, the thermostat 11
is located within the rising enlarged portion 1a. 13 is a hot water discharge port opened above the tank 1, which supplies hot water to the cleaning nozzle 14.
