DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning a human body having a hot water tank.

[0002]

2. Description of the Related Art Generally, when a sheathed heater having a large calorific value is provided inside a hot water tank of a human body local cleaning device, when the sheathed heater is energized when water is not supplied to the hot water tank, abnormal heat is generated. Damage to the hot water tank and the various parts associated therewith. For this reason, such a hot water tank is provided with various safety devices.
The hot water tank of the human body local cleaning device is the toilet bowl device 1 shown in FIG.
1 is provided with a human body local cleaning device body 12, and a warm water tank 13 made of a resin material for storing cleaning water for human body local cleaning is built in a sleeve portion of the human body local cleaning device body 12. The hot water tank 13 includes a hot water tank 13.
The sheathed heater is inserted into the hot water tank 13 through the through hole. This sheathed heater is for warming the washing water for washing the human body part to an appropriate temperature, and the lower part is bent in an L-shape. The reason for bending into the L-shape is to improve the circulation of water in the hot water tank and to secure the length of the heating portion of the heater.

Further, a metal heat sensitive plate is fixed on the upper part of the sheathed heater, and a thermal fuse is mounted on the metallic heat sensitive plate which is blown by receiving abnormally high heat from the sheathed heater or the like. However, in the conventional human body cleaning device, a portion corresponding to the position directly above the bent L-shaped horizontal portion is covered with the entire lid of the hot water tank 13 made of a resin material, and directly from the L-shaped horizontal portion to the temperature fuse. Heat transfer was not performed.

[0004]

As described above, according to the conventional technique, a portion corresponding to a position directly above the L-shaped horizontal portion of the sheathed heater is covered with the entire lid of the hot water tank made of a resin material, so that an empty space is formed. When an abnormal temperature rise occurs in the sheathed heater due to cooking or the like, heat is transmitted only through the horizontal part of the sheathed heater → the vertical part → a metal heat sensitive plate → a path of the temperature fuse to detect the abnormal temperature rise. The heat from the horizontal portion of the sheathed heater cannot be directly transferred to the thermal fuse. That is, since the lid of the hot water tank is covered with a resin material having a small heat transfer coefficient, the lid is blocked by the resin material.

Therefore, the conventional human body cleaning apparatus has a problem that the temperature transmission to the thermal fuse cannot be quickly detected.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to quickly detect a temperature transmission to a thermal fuse when an abnormal temperature rise occurs in a hot water tank and to quickly prevent damage to components.

[0007]

Means for Solving the Problems In order to solve the above technical problems, the technical means (hereinafter referred to as first technical means) taken in claim 1 of the present invention comprises: a hot water tank; A sheath heater arranged in the hot water tank and having an L-shaped lower portion, a metal heat-sensitive plate fixed to an upper portion of the sheath heater, a temperature fuse arranged on the metal heat-sensitive plate, A human body local cleaning device having a through hole formed in a hot water tank immediately above a substantially horizontal portion of an L-shaped portion of a heater, wherein a part of the metal heat sensitive plate is exposed in the through hole, A part of the thermal fuse disposed on the heat-sensitive plate is disposed within an extension of the outer shape of the through hole.

The effects of the first technical means are as follows.

That is, since the heat from the horizontal portion of the sheathed heater can be directly transmitted to the metal heat sensitive plate and the thermal fuse, the operation of detecting the abnormal temperature rise in the hot water tank can be performed in a short time. It has the effect of becoming.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described.
This will be described with reference to the drawings.

FIG. 1 is an overall perspective view of the main body cleaning device of the present invention. The hot water tank 13 is provided with a human body local cleaning device main body 12 attached to the toilet device 11, and a hot water tank 13 made of a resin material for storing cleaning water for human body local cleaning is installed in a sleeve portion of the human body local cleaning device main body 11. Have been. As shown in FIG. 2, the sheathed heater 1 is connected to the hot water tank 13 through a through hole 131 of the hot water tank 13.
4 is inserted into the hot water tank 13. The sheathed heater 14 is for heating washing water for washing a human body part to an appropriate temperature, and has a lower part bent in an L-shape.
A metal heat-sensitive plate 15 is fixed to the upper part of the sheathed heater 14, and a thermal fuse 16 is attached to the metal-heated plate 15 so as to be blown by receiving heat from the sheathed heater 14 that has become abnormally hot, such as empty cooking. ing. One end of the metal heat-sensitive plate 15 is provided with a U-shaped portion 151 bent into a U-shape. The U-shaped part 151 is provided with a cut-and-raised piece 152, and the cut-and-raised piece 152 and the tip 1 of the U-shaped part 151 are provided.
The thermal fuse 16 is fixed by the inside of the fuse 53.

The lower portion of the sheathed heater 14 is L-shaped, and includes a horizontal portion 141 and a vertical portion 142. The vicinity of the L-shaped portion is a heater heating portion. A sealing member 17 is disposed above the metal heat-sensitive plate 15 and the hot water tank 13,
Water leakage from the hot water tank 13 is prevented.

The sheathed heater 14 and the metal heat sensitive plate 15 are fixed by brazing or the like and are integrated, which is advantageous for assembling.

The upper part of the hot water tank 13 directly above the horizontal part 141 of the sheathed heater 14 is directly
5 is exposed, and the sheath heater 1 is similarly exposed.
The thermal fuse 16 is located immediately above the horizontal portion 141 of the bottom portion 15.

The thermal fuse 16 is arranged on an extension of the outer shape of the through hole 131 (dotted line in FIG. 2). FIG. 3 is a plan view of the metal heat sensitive plate viewed from above in FIG. FIG. 2 is a sectional view taken along the line AA in FIG. 3, and also shows a hot water tank.

The hot water tank 13 having the structure of this embodiment is connected to the hot water tank 1 via a water pipe by a pump or water pressure.
When the water is supplied into the hot water tank 3 and the hot water tank 13 is sufficiently supplied with water, the safety switch is closed with the float moved upward, the sheath heater 14 is energized, and the washing water in the hot water tank 13 is heated by the heat generated by the sheath heater. Then, the warmed washing water is supplied to the washing nozzle 20 of FIG. 1 by pump pressure or water pressure.

The horizontal portion of the sheathed heater of the present invention is not necessarily completely horizontal, but may be bent obliquely upward or diagonally downward. Various other methods are conceivable and are limited to the present embodiment. is not.

Also, as shown in FIG.
41, a through-hole 131 formed directly above the bent portion 141
