Description

[Detailed Description of the Invention] The present invention relates to the structure of the heating section of a hot water sanitary washer, and is capable of achieving good water heating by devising the location of the heater and temperature attachment to the heating chamber.

Generally speaking, in sanitary cleaners for anal cleaning, etc., where the water tank is detachable from the main body, installing a heater in the water tank poses problems in terms of electrical connection, etc. The device is installed in a heating chamber provided on the main body side.

As the heater, it is preferable to use an underwater heater from the point of view of heat transfer, but underwater heaters are made of glass tube heaters, sheathed heaters, etc., and are weak against stress, making installation structure and insulation difficult, and there are also problems in serviceability. There is.

For these reasons, we have considered configuring the heating chamber with a metal case and installing a heater around the entire circumference, but this makes it difficult to ensure smooth convection to the water in the upper water tank. It was difficult to operate the temperature control element normally.

The present invention eliminates these conventional drawbacks,
An embodiment will be described below based on the drawings.

In the figure, 1 is a main body case, and 2 is a water tank that can be attached to and detached from the main body case 1 from above.

Inside the main body case 1 are a motor 3 and a motor 3.
A pump 4 driven by is provided, a tube 5 is led out from the pump 4, and a nozzle body 6 is connected to the tip of the tube 5.

The water storage tank 2 has a connecting lower portion formed at its lower part, and is connected to a connecting socket 8 formed at the upper part of the main body case 1 in a watertight manner.

A water stop valve 9 is provided in the connection lower portion, and this water stop valve 9 is pushed up when the connection lower is connected to the connection socket 8 to allow water to flow therethrough.

A heating chamber 11 is provided between the connection socket 8 and the suction port 10 of the pump 4 below it.

This heating chamber 11 consists of a metal heating case 12. A gasket 13 is provided on the upper part of the heating case 12, and the gasket 13 is placed in close contact with the outer periphery of the cylindrical part 8' of the connection socket 8.
It is watertightly connected to the inlet 10 of the.

A heater 14 covering half the circumference is attached to the outside of the metal heating case 12 with a band 15, and an ON/OFF switch is attached to the outer circumference of the heating case 12 on the opposite side of the heater 14.
A temperature control element 16 is attached in a thermally conductive manner.

This temperature control element 16 is made of a thermal reed switch, is connected in series to the heater 14, and controls the energization of the heater 14 by turning it on and off.

The hot water sanitary washer of the present invention is constructed as described above, and its operation will be explained next. First, the water tank 2 is filled with water, and when it is connected to the main body case 1, the water stop valve 9
is opened, and the heating chamber 11 and pump 4 at the bottom thereof are filled with water.

Next, when the heater 14 is energized via the temperature control element 16, the inside of the heater attachment portion extending about half the circumference of the heating case 12 is heated, and the water inside is heated from the side.

The water heated here has a small apparent specific gravity, rises due to the difference in specific gravity with the water in the water tank 2, passes through the water stop valve 9, and is exchanged with ice in the water tank 2.

At this time, since the heater 14 extends around half the circumference of the heating case 12, the water in the heating chamber 11 is heated only on one side, and the water flows continuously and smoothly in the direction of the arrow in the figure. Due to the flow, the heat in the heating chamber 11 is easily transferred to the water storage tank 2.
As a result, the water in the water tank 2 is smoothly heated.

Moreover, since the temperature control element 16 is given almost the same temperature as the water in the water storage tank 2 and operates by sensing that temperature, it is possible to appropriately control the temperature.

If the heater 14 is provided over the entire circumference of the heating case 12 or around the circumference thereof, the temperature of the water in the heating case 12 will increase throughout the entire circumference, and the heated water will simultaneously pass through the water stop valve 9 and enter the water storage tank. However, the flow does not occur as shown by the arrow in the figure, and the water in the heating chamber 11 is replaced intermittently, and the temperature of the water in the heating chamber 11 rises quickly, causing the temperature control element 16 to turn off. This is too fast, and the temperature rise of the water metal body in the water tank 2 becomes slow.

Moreover, the number of ON and OFF operations increases, and the life span of the temperature control element 16 is also shortened.

By installing the heater halfway around the heating case as described above, the water temperature in the water tank rises smoothly, and the temperature control element can detect and control the temperature so that there is almost no difference in temperature from the water in the heating chamber. It has great practical effects.
