Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sanitary cleaning device that is attached to a flush toilet or the like and is configured to spray cleaning water toward private parts.

[Conventional technology]

2. Description of the Related Art Conventionally, there are toilets in which a sanitary cleaning device having an internal cleaning function and a drying function using hot air is integrally attached to a flush toilet.

This sanitary cleaning device has a built-in hot water tank that heats and stores cleaning water, a nozzle device that sprays hot water heated by the hot water tank toward private parts, etc.
Necessary cleaning can be performed using the operating section.

In addition, water is supplied to the hot water tank by fixing a joint for connecting external piping to the back of the casing of the sanitary washing device and connecting the water supply pipe to the supply pipe to the hot water storage tank.

Conventionally, as a joint for the piping system to this hot water storage tank, as shown in FIG.
2,53 is used.

When this joint is connected to a water supply pipe from the outside, it must be fixed to the casing of the sanitary washing device in order to restrict co-rotation, and a substantially L-shaped support 54 as shown in the figure is used as a support for this pipe. It is included. This support 54 has a concave cross section, and is configured to engage the nut portion 50 with side wall portions 55 located at both ends, thereby restricting rotation when connecting the water supply pipe.

[Problem that the invention attempts to solve]

However, although the conventional support 54 is made of metal from the viewpoint of strength, its relatively complicated shape requires a large number of processing steps, which is a factor in high cost.

Further, if the material is made of synthetic resin, this problem will be solved, but since it receives a large torsional stress from the nut part 50 during piping, problems regarding strength remain, and there is a possibility that it cannot be supplied as a product.

An object of the present invention is to enable a joint to be provided on a water supply pipe to a hot water storage tank to be connected to the water supply pipe without sacrificing its strength by using a support portion integrally formed on a mounting board.

[Means and actions for solving problems]

The present invention is a sanitary cleaning device that includes a hot water storage tank for heating and storing cleaning water and supplies water to the hot water storage tank from the outside.The mounting board for fixing the equipment has an opening at the upper end and a notch formed in the peripheral wall at the back of the mounting board for fixing the equipment. A cylindrical joint storage part is provided, a main body part of the cylindrical joint with a supply pipe to the hot water storage tank connected to the upper end thereof is formed to be insertable into the joint storage part, and a male screw is further provided at the lower end of the main body to connect the water supply pipe. The connecting tube is provided facing the side, and the connecting tube projects outward from the notch so that the joint body fits into the joint housing, so that the circumferential surface of the entire joint is supported by the inner surface of the joint housing. This is what I did.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Figure 1 is a perspective view of a flush toilet equipped with a sanitary cleaning device A according to the present invention, where B is the toilet body, C is a flush water tank, D and E are the toilet seat and lid, and F is inside the sanitary cleaning device A. This is a nozzle that can be moved forward and backward to spray hot water for cleaning.

FIG. 2 is a perspective view of the sanitary cleaning device A seen from the back, in which the internal equipment is covered with a mounting board 1, an upper casing 2, a side casing 3, and an operating part casing 4 made of synthetic resin.

FIG. 3 is a plan view with the upper casing 2 removed, and FIG. 4 is a sectional view taken along the - line in FIG.
G is a hot water storage tank for heating and storing cleaning water, H is a valve unit for supplying cleaning water, is a nozzle device, and J is a hot air fan for drying.

5 is a plan view of the mounting portion of the mounting board 1 to which the hot water tank G is attached, and FIG. 6 is a cross-sectional view taken along the - line in FIG. A joint storage portion 10 is formed by extending downward, and a notch 12 is formed in the peripheral wall 11 in the axial direction.
has been established.

Reference numeral 15 designates a joint inserted from above into this joint housing 10, and as shown in FIG.
A wash water supply pipe 17 to the hot water tank G side is connected to the upper end of the tank.

Further, a connecting cylinder 20 with a male screw 19 for connecting an external water supply pipe is connected to the lower side of the main body part 16 by brazing or the like and protrudes laterally.

A cleaning water supply pipe 17 is previously inserted into the upper end of the joint 15 and connected by brazing or the like, and the pipe is fitted and fixed into the joint storage portion 10.

Then, equipment such as the hot water tank G, valve unit H, nozzle device I, and hot air fan J are fixed to the mounting board 1, and the cleaning water supply pipe 17 is connected to the valve unit H to allow the cleaning water to flow to the nozzle device I. connect the wiring from the operation unit to each device. Furthermore, the upper part, side parts and operation part casings 2 to 4 are connected to this mounting board 1, and the toilet main body B
Secure in place with fixing bolts (not shown).

Next, an external water supply pipe S is connected to the connecting tube 20 protruding from the notch 12 via a packing 31 with a cap nut 30, and a cord 41 is connected to a connector 40 for electrical wiring provided at the lower part of the joint housing 10. Connect.

In FIG. 4, reference numeral 21 denotes a bush which covers the male screw 19 and is fixed to the upper and side casings 2 and 3.

In the connection between this connecting tube 20 and the water supply pipe S,
When the cap nut 30 is tightened, the main body 16 of the joint 15 also becomes inclined within the joint housing 10 in the direction of rotation thereof. Here, the main body 16 of the joint 15 is made as long as possible within the narrow space, and the male thread 19 is located on the lower side, so that when rotating, the main body 16
The force that acts on the joint housing 10 when 6 tries to tilt is applied as a rotational moment to the upper end of the main body 16, but the force acting is very small because the dimension between the male screw 19 and the upper end of the main body 16 is long. Become.

Therefore, when the water supply pipe S and the connecting tube 20 are connected, a large stress concentration does not occur locally in the joint housing part 10, and the mounting board 1 provided with the joint housing part 10 can be made of synthetic resin. However, there is no problem in terms of strength.

As described above, the joint 15 for water supply can be placed in the synthetic resin casing of the sanitary washing device A without the need for special support fittings, etc., making piping easy and reducing costs. be.

[Effect of idea]

In the present invention, since the joint can be supported by the joint storage part provided integrally with the mounting board, production efficiency can be improved by reducing the number of parts and simplifying piping work, and the cost can be reduced.
