Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand shower used in a shower room or a bathroom. .

[0002]

2. Description of the Related Art Generally, a hand shower is installed in a shower room or a bathroom. When using it, turn the ring of the hand shower, etc. to discharge hot water from the hand shower head and use it.After use, turn the ring of the above hand to stop the injection of hot water and keep that state until the next use. To be done.

[0003]

However, when the bathroom is heated to a high temperature using a sauna or the like, the conventional hand shower has a function of draining water in the middle of the pipe from the mixed faucet to the hand shower head. Since it was not provided, even if the hot and cold water remaining in the pipe leading to the hand shower head was heated to a high temperature, it was not possible to remove the hot and hot water before using the hand shower with the conventional configuration.

Therefore, when a bather uses a hand shower, there is a risk of taking hot water.
There were problems such as feeling uncomfortable and getting burned. The present invention was developed in view of the above points,
The purpose of this is to provide a hand shower in which the bather does not take hot water that has accumulated in the piping leading to the hand shower when the bathroom is used at high temperature. It is in.

[0005]

In order to effectively achieve the above object, the present invention has the following structure. That is, in the mixed faucet and the hand shower head arranged in the bathroom, the drainage pipe is connected in the middle of the water passage pipe from the mixed faucet to the hand shower head, and the vicinity of the connection point of the drainage pipe. In the water passage pipe, a pipe sealing means is provided to seal the drainage pipe when the hand shower is used to open the water passage pipe, and to open the drainage pipe when the hand shower is not used. This is a configuration in which the water passage pipe can be sealed.

[0006]

With the above-structured hand shower, during normal use of the hand shower, hot water is passed from the mixing faucet to the hand shower head through the water passage pipe, whereby the pipe sealing means is made to pass water. It is acted on by hot water, and the water piping is opened to allow hot water to flow from the mixed faucet to the hand shower head. Simultaneously with the opening of the water passage pipe, the drainage pipe communicating with the water passage pipe is sealed by the action of the pipe sealing means, and hot water is prevented from being discharged from the drainage pipe.

On the other hand, when the hand shower is no longer used, water stops flowing from the mixing faucet, so that the pipe sealing means acts to open the drainage pipe, and at the same time,
The water supply pipe will be sealed. As a result, the hot and cold water in the water flow pipe from the pipe sealing means installation location to the hand shower head is drained from the drain pipe.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2 show the essential parts of a hand shower according to a first embodiment of the present invention, and as shown in FIG. 7, a mixed faucet 1 and a hand shower head 2 are arranged in the bathroom. As shown in FIGS. 1 and 2, a water passage pipe 3 is arranged from the mixed faucet 1 to the hand shower head 2, and a drainage pipe 4 is connected in the middle of the water passage pipe 3,
The water passage pipe 3 and the drainage pipe 4 communicate with each other.

A pipe sealing means 5 is inscribed in the water passage pipe 3 near the connection point of the drainage pipe 4. That is, the pipe sealing means 5 is composed of the valve body 6, the tension spring 7, and the spring fixture 8, and the spring 7 is placed on the spring fixture 8 fixed to the inner wall of the water passage pipe 3. ing. The lower end of the spring 7 is locked to the spring fixture 8 and the upper end is locked to the valve body 6.

The valve body 6 is formed so as to be able to seal the passage 9 of the drainage pipe 4 branched from the water passage pipe 3. The valve body 6 of the first embodiment has a cross section as shown in the drawing. It is an inverted L-shaped member, and the upper end of the spring 7 is locked to the convex portion 6a of the valve body 6. In the above configuration, when using the hand shower, hot water flows from the mixed faucet 1 to the hand shower head 2 through the water passage pipe 3. At this time, the valve body 6 moves upward in the water pipe 3 due to the water pressure of the hot water flowing from the mixed faucet 1 against the elastic force of the tension spring 7 as shown in FIG. The water passage pipe 3 sealed by the body 6 is opened, and the drainage pipe 4 branched from the water passage pipe 3 is sealed by the valve body 6. As a result, the hot and cold water flowing from the mixed tap 1 is guided to the hand shower head 2 side.

On the other hand, when the use of the hand shower is stopped, the water pressure of the hot water in the water supply pipe 3 is also reduced, and the valve body 6 that seals the drainage pipe 4 has a tension spring 7 as shown in FIG. It is returned to the position of the spring fixture 8 by the elastic force to open the drainage pipe 4 and seal the water passage pipe 3. As a result, the hot and cold water accumulated in the water passage pipe 3 from the pipe sealing means 5 in the water passage pipe 3 to the hand shower head 2 is discharged outward from the opened drainage pipe 4, The water flow pipe 3 from the pipe sealing means 5 in the water pipe 3 to the hand shower head 2 is emptied.

Due to the above-mentioned operation, when the hand shower is used with the bathroom kept in a high temperature state, the water stays in the water pipe 3 from the pipe sealing means 5 in the water pipe 3 to the hand shower head 2. Bathers will not be exposed to hot water when using the shower. 3 to 4 show the second embodiment, and since the configuration other than the valve body 6 is almost the same as the configuration of the first embodiment, the description thereof will be omitted. Therefore, the valve body 6 of this embodiment has a quadrangular cross section as shown in the drawing, and seals the drainage pipe 4 by fitting it into the drainage pipe 4 branched from the water passage pipe 3.

5 to 6 show a third embodiment, and the structure other than the valve body 6 is almost the same as the structure of the first embodiment, and the explanation thereof will be omitted. Therefore, the valve body 6 of this embodiment is a sphere as shown in the drawing, and is fitted into the drainage pipe 4 branched from the water passage pipe 3 to seal the drainage pipe 4.
In the drainage pipe 4, a protrusion 10 for locking the valve body 6 is provided in the drainage pipe 4. Further, in order to prevent the valve body 6 from going into the water passage pipe 3 reaching the hand shower head 2 side, a convex portion 11 is also provided in a portion of the water passage pipe 3 which is branched from the drainage pipe 4.

[0014]

As is apparent from the above description, according to the present invention, when the hot water discharge from the hand shower head is stopped, the action of the pipe sealing means causes the hand shower from the pipe sealing means in the water passage pipe. Hot water up to the head is drained from the drainage pipes and disappears.Therefore, even when using a hand shower with the bathroom at a high temperature, the hot water does not get heated and you feel uncomfortable or burn when taking a shower. You can take a shower without having to.
