DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view showing a connection structure of a water supply connection pipe of a hot water flush toilet seat according to a first embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a hot water flush toilet seat body mounted on a toilet bowl (not shown), and a water supply inlet 6 provided at a rear corner of the hot water flush toilet seat body 1 and a water main pipe in a building. The water tap 2 on the side is connected by a flexible connecting pipe 3 (pressure-resistant hose) to supply tap water to the hot water flush toilet seat body 1.

Reference numeral 3a denotes an end of the connecting pipe 3, and the connecting pipe end 3a is provided with a synthetic resin connecting device connected to the feed water inlet 6. 6 is connected so as not to leak water.

Reference numeral 4 denotes a holder attached to the back of the warm water flush toilet seat main body 1, and the connecting pipe 3 is fixed to the holder 4 with the connecting pipe 3 interposed therebetween. While the holder 4 is attached to the hot water flush toilet seat body 1 in the embodiment of FIG. 1, a double-sided adhesive tape is used. However, when the holder 4 is used in an environment where the water hammer phenomenon is extremely severe, screwing is preferable. .

Here, the role of the holder 4 will be further described as follows.

Since the connecting pipe 3 is connected to the water main and is under water pressure, it suffers from the water hammer phenomenon described in the prior art. Since the connecting pipe 3 is a flexible hose such as a pressure-resistant hose, if the middle of the connecting pipe 3 is left in a free state without using the holder 4 as in the related art, the connecting pipe 3 is swung left and right by a water hammer phenomenon. In addition, a large vibration of the internal pressure of the connecting pipe 3 is also applied, and the connecting pipe end 3a connected to the feed water inlet 6 has:
A complicated and large force is applied to loosen the connecting tool of the connecting pipe end 3a to cause water leakage, and furthermore, to damage the connecting pipe end 3a.

If the whirling of the connecting pipe 3 near the connecting pipe end 3a due to the water hammer phenomenon is suppressed, the connecting pipe end 3
The force of repeatedly bending a becomes weaker, and the possibility of loosening or breakage of the connecting pipe end 3a is eliminated. Therefore, in the embodiment of FIG. 1, one holder 4 is provided on the back of the hot water flush toilet seat body 1.
Was attached, and the intermediate portion of the connection pipe 3 was sandwiched and fixed to the holder 4.

By fixing the intermediate portion of the connecting pipe 3 to the hot water flush toilet seat body 1 as described above, the vibration of the swiveling of the connecting pipe 3 due to the water hammer phenomenon is absorbed by the hot water flush toilet seat body 1 and the connecting pipe 3 It hardly reaches the end 3a. Further, even if a cleaning tool is applied to the connecting pipe 3 between the water faucet 2 and the holder 4 by cleaning or the like in the toilet or the like and a force is applied thereto, this force is also blocked by the hot water flush toilet seat body 1 and the connection is made. No force is applied to the tube end 3a. In addition,
Although the holder 4 and the connecting pipe 3 are firmly fixed and held in many cases, the effect of absorbing the impact vibration of the water hammer phenomenon is great. The effect on 3a is suppressed.

FIG. 2 is a perspective view showing a connection structure for a water supply connection pipe of a hot water flush toilet seat according to a second embodiment of the present invention.

In FIG. 2, two holders 4, 4 are attached to the back of the hot water flush toilet seat body 1, and the connecting pipe 3 is fixed to the hot water flush toilet seat body 1 at two places. The other points are the same as those of the embodiment of FIG. 1 except for the points of difference from the first embodiment. In the second embodiment, the portion of the connecting pipe 3 between the two holders 4, 4 is more strongly fixed than that shown in FIG. The effect on 3a is further suppressed.

FIG. 3 is a partial sectional view of a hot water flush toilet seat showing a structure for connecting a water supply connection pipe of the hot water flush toilet seat according to a third embodiment of the present invention.

In FIG. 3, a holder 4a is formed so as to protrude integrally with the outer casing 5 on the back of the hot water flush toilet seat body 1,
The connecting pipe 3 is inserted into a through hole 7 provided at the center of the holder 4a, and the through hole 7 surrounds the periphery of the connecting pipe 3 near the connecting pipe end 3a so as to suppress whirling. is there. As described above, when the holder 4a holds the connecting pipe 3 very close to the connecting pipe end 3a, the connecting pipe 3 is firmly attached to the hot water flush toilet seat body 1 as in the first or second embodiment. Even if it is not fixed, the effect of suppressing the whirling of the connecting pipe 3 becomes sufficiently large. In addition, even if a cleaning tool is applied to the connecting pipe 3 between the water faucet 2 and the holder 4a due to cleaning of the toilet or the like and a force is applied thereto, the influence on the connecting pipe end 3a is suppressed.

FIG. 4 is a partial sectional view of a hot water flush toilet seat showing a connection structure of a water supply connection pipe of the hot water flush toilet seat according to a fourth embodiment of the present invention.

In FIG. 4, the holder 4a according to the third embodiment is attached to the outer shell 5 of the toilet body 1, instead of the outer shell 5b on the back of the toilet body 1. . Other configurations and operations are the same as those of the third embodiment.

In any of the above-described embodiments, the position of the intermediate portion holding the connecting pipe 3 is set to a position within about 10 times the diameter of the connecting pipe 3 from the connecting pipe end 3a on the feed water inlet 6 side. Then, the whirling of the connecting pipe 3 on the connecting pipe end 3a side due to the water hammer phenomenon becomes small, and the force applied to the connecting pipe end 3a to bend the connecting pipe 3 becomes very weak. The result of the experiment confirmed that the effect of preventing damage and loosening of the connecting pipe end 3a during use of the toilet seat was remarkable.

It is apparent that the effect of the water hammer phenomenon on the connecting pipe end 3a and the influence of the cleaning tool hitting the connecting pipe end 3a can be suppressed even if the connecting pipe end 3a is held by another member such as a low tank or a toilet.

[0026]

As described above, according to the present invention, even if a large force or vibration is applied to the flexible connecting pipe due to the water hammer phenomenon or the cleaning of the toilet, a force is applied to the connecting end of the connecting pipe. And vibrations are less likely to be applied, and loosening or breakage of the end of the connecting pipe can be prevented.

In particular, if the intermediate portion of the connecting pipe is held by the body of the warm water washing toilet seat instead of other members such as a low tank in the toilet, the body of the hot water washing toilet seat and the connecting pipe can be held in advance, and It greatly contributes to streamlining of toilet seat construction and maintenance.
