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 inside the casing, a nozzle device that sprays heated hot water toward private parts, etc., and can perform the necessary cleaning using the operating section. .

The cleaning water is supplied by connecting the internal pipe to the external supply pipe via a joint, and a cylindrical storage part is formed at the back of the casing to accommodate the joint.

[Problem that the invention attempts to solve]

However, the fitting is simply inserted into the storage compartment;
The fixed state is maintained using the restraining force of the connected piping on the water supply side and hot water tank side, so if an electromagnetic pump etc. is installed in the piping system inside the casing, the piping will vibrate and the fitting will also vibrate inside the storage compartment. cause a phenomenon.

Therefore, due to the contact between the casing and the joint,
This may generate noise or cause wear on both parts, which may cause accidents such as water leakage.

In addition, to deal with such vibrations, hoses made of elastic materials are used in the piping system, but in order to add a buffering function, the hoses must be made long and slack, which takes up a large amount of space for piping. There is also the issue of becoming.

An object of the present invention is to elastically support a joint provided on a water supply pipe to a hot water tank in a casing in a sanitary cleaning device, and to protect the joint and the casing by a vibration buffering function.

[Means and actions for solving problems]

This invention is a sanitary cleaning device that is equipped with an electromagnetic pump and has a fitting on a mounting board that connects an external water supply pipe to piping to a hot water tank for cleaning. A cylindrical joint housing with a notch for connecting pipes is provided, and the joint is inserted and fixed into the joint housing with a buffer made of an elastic material interposed therein, and the buffer absorbs and damps vibrations in the piping system. This is how it was done.

〔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 placed anywhere on the body and sprays hot water for cleaning.

Figure 2 is an internal plan view of the sanitary cleaning device A, where G is a hot water tank that heats and stores cleaning water, H is an electromagnetic pump that supplies cleaning water, and I is connected to the hot water tank G and drives the nozzle F forward and backward. Nozzle device and J
is a hot air fan for drying. These devices are fixed to a mounting board 1 connected to the toilet main body B, and the upper part, side parts, and operation part casings 2, 3, and 4 are integrated with this mounting board 1. In addition, a shock absorber (not shown) such as anti-vibration rubber is placed between the lower surface of the electromagnetic pump H and the mounting board 1, so that the mounting board 1 during operation
absorb vibrations.

At the left end of the back of the mounting board 1, a cylindrical joint accommodating part 10 with an open upper end is formed extending downward, and a notch 12 is formed in the peripheral wall 11 in the axial direction.
has been established.

Reference numeral 15 denotes a joint inserted into the joint storage portion 10 from above, and the upper end thereof connects a wash water supply pipe 17 to the hot water tank G side and a water supply pipe 18 piping to the outside. Also, on the discharge side of the electromagnetic pump H is a hot water tank G.
A communication pipe 19 is installed between them, and in order to cope with the vibrations of the electromagnetic pump H, the cleaning water supply pipe 17 and the communication pipe 19 are made of a soft silicone tube.

FIG. 3 is an exploded perspective view showing the joint storage section 10 and the joint 15. The joint 15 has a substantially L-shaped conduit and has both ends connected to the wash water supply pipe 17 and the water supply pipe 18 as connection parts 20 and 21. The connecting portions 20 and 21 are provided with flanges 22 and 23 for locking the tubes 17 and 18, respectively.

Reference numerals 24 and 25 designate flanges of different diameters provided at intervals on the connection portion 20 side of the cleaning water supply pipe 17, with the lower flange 25 having a larger diameter.

Furthermore, 26 is a cylindrical shock absorber made of sponge rubber or the like that fits between the flanges 24 and 25, and as shown in the cross-sectional view of FIG.
The inner portion of the joint 15 is covered with the joint 15 and is placed in close contact with the inner wall of the joint storage portion 10 . In addition, in FIG. 2, 30 is a bush made of an elastic material that fits into the notch 12.

When the joint 15 with this shock absorber 26 attached is inserted into the joint housing 10, the shock absorber 26 contracts due to its elasticity, and the joint 15 is fixed by the elastic reaction force received from the inner wall of the joint housing 10. .

Since the entire circumference of the joint 15 located inside the joint housing 10 is covered with a buffer 26, even if vibration is applied to the piping system due to the operation of the electromagnetic pump H, the motor of the nozzle device I, etc. too,
The buffer body 26 absorbs and attenuates this.

Further, since the joint 15 is always maintained in a stationary state by the elastic force of the buffer body 26, no noise is generated even when vibrations are applied.

As described above, the joint 15 and the inner wall of the joint housing 10 are protected by the buffer body 26 against external vibrations, so wear and damage can be prevented.
The members such as the joint 15 and the mounting board 1 can be made of synthetic resin without any problem.

[Effect of idea]

In the present invention, since the joint is protected by a shock absorber made of an elastic material, even if vibration is applied to the piping system, the shock absorber absorbs and attenuates it, thereby preventing the generation of noise and damage to members.
