Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a local cleaning device using a ceramic heater and in which the ceramic heater forms part of a flow path.

Conventionally, this type of local cleaning device has connected a joint connected to a ceramic heater and a device upstream thereof with a metal pipe.

However, due to variations in the firing dimensions of the ceramic heaters mentioned above, it is not possible to accurately measure the dimensions between the joint connected to the ceramic heater and the upstream equipment, resulting in bending damage to the ceramic heater during piping. There have been problems such as damage due to excessive force, and destruction of a part of the ceramic heater which is the weakest in terms of strength because there is no part to absorb external forces such as vibrations.

The present invention aims to solve the above-mentioned problems and prevent the ceramic heater from being destroyed during piping or when external forces such as vibrations are applied.

The basic configuration of this invention is a ceramic heater of the heating device.
By connecting a joint pipe to the inlet of the heating device and connecting the joint pipe and equipment on the upstream side of this heating device with a flexible hose, variations in dimensions such as the firing dimensions of the ceramic heater and external forces can be absorbed. It is something.

Hereinafter, the present invention will be described in detail based on illustrated embodiments.

A in the figure is the wash water main water supply line, and in this line, from the upstream side, there is a flow rate adjustment valve c1 integrally provided on the secondary side of the solenoid valve base a, a heating device d1, and a valve that also serves as a check valve. A vacuum breaker e and a cleaning nozzle f are sequentially arranged, and the cleaning nozzle f is the end of the (cleaning aquatic) water supply line A.

B is a wash water auxiliary water supply line, which is branched from the above-mentioned wash water main water supply line A via a second vacuum breaker g that is integrally connected to the secondary side of the flow rate adjustment valve C, and at its end. An auxiliary nozzle h is provided.

It should be noted that the second vacuum breaker g mentioned above is also configured to function as a check valve like the first vacuum breaker e.

The main water supply line A and the auxiliary water supply line B are attached to the bottom plate 2 together with other functional parts, and covered with a box-shaped cover 1 to which the toilet seat 3 and the toilet lid 4 are attached so as to be able to vibrate freely. This constitutes case C.

Note that the cleaning nozzle f and the auxiliary nozzle h protrude from the bottom surface of the functional unit housing case C at the front center thereof to the outside of the case C.

The cleaning nozzle f and the auxiliary nozzle h are provided adjacently, and the former f
The latter faces the front, and the latter faces the rear.

The electromagnetic valve is configured to open when energized and water supplied from the upstream side flows to the flow rate regulating valve C side, and the flow rate regulating valve C has a structure in which the water supplied from the upstream side flows to the flow rate regulating valve C side. A second vacuum breaker has an outlet 6.5 on the top and side, and the outlet 5 on the top is integrally connected to the second vacuum breaker.
An elbow joint 8 is connected to the connecting pipe 7 via g, and an auxiliary nozzle h is connected to the auxiliary nozzle h via the connecting pipe 7. For example, it is connected via a nylon hose 9 to a heating device d.

In addition, a ceramic heater 1 described later in the heating device d
A joint pipe 10 is attached to the inlet of the hose 1, and the flexible hose 9 is connected to the heating device d via the joint pipe 10.

Heating device d is heating can 1 equipped with ceramic heater 11
2, and a hot water storage can 14 which is brazed along the heating can 12 and communicates with the heating can 12 via a conduit 13, and a first vacuum breaker-e is attached to the hot water storage can 14. The heating device d communicates with the cleaning nozzle f via the first vacuum breaker e and the communication pipe 15 connected thereto.

The heating and hot water storage cans 12 and 14 are made of a metal with good thermal conductivity, such as copper.

The ceramic heater 11 is made of alumina, and has a heating element and a sensor (both not shown) printed on the surface of a rod-tube-shaped base body with a hole 16 opened in the axial direction and placed adjacent to each other. The lid 17 that closes the opening of the heating can 12 is fixedly attached to the lid 17 by penetrating the center thereof, and by attaching the lid 17 to the heating can 12, the inner peripheral surface of the heating can 12 and the inner peripheral surface of the heating can 12 are properly connected. The heating can 12 is inserted into the heating can 12 so as to have a certain gap therebetween.

The heating element and sensor are provided in the portion of the ceramic heater 11 that is inserted into the heating can 12, and the aforementioned flexible hose 9 is connected to the inlet portion of the ceramic heater 11 that protrudes outward from the lid 17. The joint pipe 10 is fixedly attached so as to communicate with the hole 16 of the heater 11.

The lid 17 is fixed to a flange 18 provided at the opening of the heating can 12 with screws 19.

To connect the flow rate regulating valve C and the heating device d, first attach the joint pipe 10 to the inlet of the ceramic heater 11.
After connecting the flexible hose 9 to this, the lid 17 is attached to the heating can 12, and the other end of the flexible hose 9 is connected to the elbow joint 8 attached to the flow rate regulating valve C.

In addition, 20 is a cap nut, and 21 is a pull-out prevention device. By twisting the cap nut 20, this pull-out prevention device 21 is inserted into the elbow joint 8 and the joint pipe 10 into the flexible hose 9.
Connect in a grip-like manner.

Further, in the figure, 22 is a controller that is electrically connected to the heating element and sensor of the ceramic heater 11 and controls the temperature of the cleaning water to a predetermined temperature, 24 is a switching element thereof, and 23 is the controller 22. This is a safety bimetal switch that prevents the wash water from becoming overheated due to a malfunction.

In this private part cleaning device, the toilet seat 3 is installed around the ball part 28 of the toilet bowl using a bolt 26 that can be inserted into the mounting hole 25 formed in the bottom plate 2 of the functional storage case C and a nut 27 that is screwed onto the bolt 26. The cleaning nozzle f and the auxiliary nozzle h correspond to the upper surface of the rim 29 and are attached to the toilet bowl so as to protrude into the toilet bowl portion 28 for use.

In such a state of use, when the user sits or straddles the toilet seat 3, the cleaning nozzle f faces the user's anus or genital area, and the auxiliary nozzle h faces the rear rim surface 29 of the toilet seat.

Since the present invention has the above configuration, it has the following advantages.

■ A ceramic heater is inserted into the heating can in the middle of the cleaning water supply line that supplies cleaning water to the cleaning nozzle, and the ceramic heater is connected to the upstream side of the water supply line through a hole that passes through it in the axial direction. In the private parts cleaning device equipped with a heating device, a joint pipe is connected to the inlet of the ceramic heater of the heating device, and the joint pipe and the equipment on the upstream side of the heating device are connected by a flexible hose. It is possible to absorb variations in dimensions such as firing dimensions of the ceramic heater, eliminate unnecessary force from acting on a part of the ceramic heater when assembling the equipment, and prevent vibrations during transportation or construction, or water during use of the equipment. Flexible hoses can absorb external forces such as the flow of water and vibrations caused by opening and closing the toilet seat, so during piping, bending destructive force may be applied to a part of the ceramic heater, or the ceramic heater may be damaged due to vibration, etc. can be prevented.

■ Compared to conventional metal pipes, flexible tubes make it easier to connect the ceramic heater and upstream equipment, improving work efficiency and reducing costs. .
