BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water tank provided in a hot water flush toilet, which is formed by welding an upper half and a lower half separately manufactured by a synthetic resin or the like. It is an object of the present invention to reduce the burden on the welded portion between the upper half and the lower half after being easily attached.

[0002]

2. Description of the Prior Art FIG. 3 shows the internal structure of a conventionally used hot water flush toilet 30. As shown in FIG.
2. A hot water tank 38 for heating the cleaning water to generate hot water, an electromagnetic pump 36 for supplying the hot water from the hot water tank 38 to the cleaning nozzle 41, and the like are provided.

[0003] Inside the water storage tank 38, together with a float valve 42, an overflow pipe 43, a ball tap 31, etc., an auxiliary tank 33 for preferentially supplying washing water discharged from the ball tap 31 to the hot water tank 38.
Cliffs are provided.

On the other hand, inside the hot water tank 38, a heater 40 for heating the washing water, a thermistor 39 for detecting the water temperature, and the like are provided.

[0005] The water storage tank 32 and the hot water tank 38 are connected by a water supply hose 35. 34 is
This is a degassing hose for discharging air from the hot water tank 38.

The washing water supplied to the ball tap 31 via the water stopcock 37 is discharged from the ball tap 31 into the auxiliary tank 33 when the water level in the water storage tank 32 decreases. The auxiliary tank 33 supplies washing water preferentially to the hot water tank 38 and distinguishes between washing water for the warm water tank 38 and washing water for toilet bowl washing. For example, the auxiliary tank 33 is provided with a hand washing machine. Hand washing water is not supplied to the hot water tank when it is used.

The cleaning water supplied from the auxiliary tank 33 to the hot water tank 38 through the water supply hose 35 is stored while being heated to an appropriate temperature by the heater 40, and is operated by the electromagnetic pump 36 to the cleaning nozzle 41 through the water supply hose 35. It is supplied and discharged.

Water is supplied to the water storage tank 32 by the auxiliary tank 3.
The cleaning water is supplied preferentially into the hot water tank 38 via the third tank 3 and then overflows from the auxiliary tank 33.

[0009]

The hot water tank 38 used for the hot water flush toilet 30 has a flange 5 formed on the side peripheral surface.
1 is supported on the inner surface of the toilet 30, so that it is installed in the toilet 30 with a hanging bear. Therefore, the hot water tank 38 is made of an upper half 38a and a lower half 38 using synthetic resin or the like.
b are manufactured separately and then integrated by welding. When the inside is filled with washing water, the load is increased by welding the upper half 38a and the lower half 38b of the hot water tank 38. By acting on the part 50, it works in a direction to separate them. Therefore, conventionally, there was a possibility that water might leak at the welding portion 50 of the hot water tank 38. Further, in order to prevent water leakage, the welding strength between the upper half portion 38a and the lower half portion 38b must be made extremely large, so that there is also a problem in that it takes time and effort in manufacturing.

[0010]

SUMMARY OF THE INVENTION The present invention is to provide a novel hot water tank structure which can solve the above-mentioned conventional problems, and is characterized by being separately manufactured. The upper half portion and the lower half portion are welded to each other, and the lower peripheral portion has a side peripheral surface on which an attachment portion to the hot water flush toilet is formed.

[0011]

According to the structure of the hot water tank according to the present invention, the upper half and the lower half of the separately manufactured upper half and the lower half have a mounting portion for the hot water flush toilet on the side peripheral surface of the lower half. Therefore, when the mounting portion is attached to the inner surface of the toilet and the hot water tank is supported in a suspended state, the load of the washing water filled therein is increased with respect to the welded portion between the upper half and the lower half. Does not act in the direction of separating Thus, there is no risk of water leakage.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing a hot water flush toilet A provided with a hot water tank 1 according to the present invention.

In FIG. 1, reference numeral 2 denotes an auxiliary tank, reference numeral 3 denotes a water storage tank, reference numeral 4 denotes a ball tap, reference numeral 5 denotes a washing nozzle, and reference numeral 6 denotes a support plate for installing the water storage tank 3 in a toilet.

The hot water tank 1 is formed by welding an upper half portion 1a and a lower half portion 1b which are separately manufactured of a synthetic resin.
In the present embodiment, as shown in FIG. 2, a flange 11 is formed on the side peripheral surface of the lower half 1b to form a mounting portion, and the lower half 1b is attached to a mounting portion 7a of a mounting plate 7 mounted on the toilet A. And the flange 11 is brought into contact with the mounting plate 7. As a result, the hot water tank 1 is installed in the toilet A while being supported by the flange 11 on the side peripheral surface.

The hot water tank 1 installed as described above
The load when the washing water is filled is supported by the flange 11. Since the welded portion 10 between the upper half 1a and the lower half 1b is located above the flange 11, no load acts on the welded portion 10. Therefore, there is no danger that the upper half 1a and the lower half 1b are separated, and no water leakage occurs.

The embodiment of the present invention is not limited to the above. For example, the position and shape of the mounting portion formed in the lower half of the hot water tank can be appropriately changed according to the installation situation. In addition to the flange, the lower half 1b
May be a groove recessed in the side peripheral surface of. In this case,
The hot water tank 1 is supported by fitting a fitting fixed to a fitting plate or a toilet into the groove.

In addition, the embodiment of the present invention does not prevent an appropriate change according to installation conditions and the like.

[0019]

The hot water tank according to the present invention has a mounting portion formed in the lower half, so that the welded portion to the upper half is located above the mounting portion. Therefore, since the load when the washing water is filled in the hot water tank does not act on the welded portion, a crack is generated between the upper half and the lower half and the two are never separated. Absent. Accordingly, there is no risk of water leaking at the welded portion, and it is not necessary to particularly increase the welding strength between the upper half and the lower half, thereby facilitating production.
