Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a shower system.

More specifically, the present invention relates to an improvement of a drainage structure of hot water remaining on the shower nozzle side in a shower system in which hot water is branched and supplied to a large number of various shower nozzles.

[Prior Art] Conventionally, for example, a shower system shown in FIG. 7 is known.

In this conventional shower system, a water passage D is branched and connected from a hot and cold water mixing tap A for mixing hot water to a large number of various shower nozzles C such as a head shower, a hand shower, and a body shower via a main tap B. The hot and cold water is discharged from each of the shower nozzles C.
Further, each water passage D is equipped with a solenoid valve E,
Discharge of hot water from each shower nozzle C can be individually controlled.

Further, in this conventional shower system, a water supply valve Ea for supplying and stopping hot water discharged from the shower nozzle C to the solenoid valve E and a drain valve Eb for discharging hot water remaining on the shower nozzle C side are integrated. A drainage structure is provided for preventing the discharge of hot and cold water having an unsuitable temperature due to residual hot and cold water on the shower nozzle C side.
A drain passage F having a drain plug G is branched between the plug B and the solenoid valve E.

[Problems to be Solved by the Invention] In the above-mentioned conventional shower system, when the hot water is drained from the shower nozzle C side, the drained hot water passes through the water passage D until it reaches the drain passage F. However, since the portion for both water supply and drainage becomes long, it is extremely unsanitary.

Further, during this drainage, the main plug B is "closed".
Since the drainage faucet F is "opened", there is a problem that hot water cannot be discharged from all the shower nozzles C.

The present invention has been made in consideration of such a problem, and the hot water remaining on the shower nozzle side can be drained sanitarily, and the drainage of each shower nozzle affects other shower nozzles. It is an object of the present invention to provide a shower system that can be individually performed without giving a shower.

[Means for Solving the Problems] In order to solve the above-mentioned problems, a shower system according to the present invention is configured such that hot water discharged from a shower nozzle is connected to a water passage connected to a large number of shower nozzles. In a shower system including a solenoid valve integrally assembled with a water supply valve for supplying and stopping and a drain valve for draining hot water remaining on the shower nozzle side, drain water is supplied to the secondary side of water supply of each solenoid valve. A means is provided, in which a valve is provided, each drainage valve is connected to each drainage valve, a drainage channel dedicated to drainage is provided in a system separate from the water channel, and the upstream side of the electromagnetic valve of the water channel is dedicated to water supply. To adopt.

[Operation] According to the above-mentioned means, when the hot water is drained from the shower nozzle side, the drained hot water all flows into the drainage channel exclusively for drainage from the drain valve provided on the secondary side of the water supply of the solenoid valve. Then, since the water does not flow from the solenoid valve to the upstream water passage at all, and the upstream side from the solenoid valve of the water passage is dedicated to water supply, the portion for both water supply and drainage is shortened, which is extremely hygienic. Furthermore, since the drainage path is connected to each solenoid valve, it is possible to discharge hot and cold water with a shower nozzle other than the shower nozzle that drains hot and cold water.

For this reason, it is possible to provide a shower system in which hot water remaining on the shower nozzle side can be drained in a sanitary manner, and the drainage can be performed individually for each shower nozzle without affecting other shower nozzles. The purpose is achieved.

[Embodiment] The first embodiment of the shower system according to the present invention will be described below.
A description will be given with reference to FIGS.

In this embodiment, as shown in FIG.
A structure similar to that of the conventional example shown in the figure is adopted, and the one implemented in the shower tower T installed in a bathroom or the like as shown in FIG. 2 is shown.

As shown in detail in FIGS. 3 to 6, the solenoid valve 1 of this embodiment has a primary water supply pipe 11 and a drain pipe 12 arranged in the lateral direction, and can be compactly connected in the lateral direction. It has a possible structure. The water supply valve 13 of this solenoid valve 1 is a primary water supply pipe.
Valve seat 13a provided so as to be orthogonal to 11 and solenoid 1
It is composed of a diaphragm type valve element 13c which is moved toward and away from the valve seat 13a by 3b. In addition, the drain valve 14 of this solenoid valve 1
A valve seat 14a provided so as to be orthogonal to the drainage pipe 12 and a direct acting valve body that is operated to move toward and away from the valve seat 14a by a solenoid 14b.
It consists of 14c. These water supply valve 13 and drain valve 14 are arranged vertically with the water supply valve 13 above and the drain valve 14 below, and are connected by a water supply secondary passage 15. It should be noted that a water supply secondary pipe 2 (which is connected to the shower nozzle C) which is in communication with the water supply secondary passage 15 can be connected to an upper portion of the solenoid valve 1 in a direction orthogonal to the water supply primary pipe 11 (Fig. 3). Connection port 16 is provided,
In the lower part of the solenoid valve 1, there is provided a continuation port 17 which communicates with the water supply secondary passage 15 and which can connect the drainage main pipe 3 in a direction orthogonal to the drainage pipe 12 (see FIG. 4).

The solenoid valve 1 of FIG. 4 is not connected to the shower nozzle C side for the purpose of connecting the drain main 3 for collecting drainage, but it has the same structure as the solenoid valve 1 of FIG. We avoid inconveniences such as cost increase due to the use of special specifications.

This solenoid valve 1 includes a water supply primary pipe 11, a water supply 2 passage 15, and a water supply 2
The secondary pipe 2 constitutes a part of the water passage D, and the drain pipe
12, The drainage main 3 constitutes a part of the drainage channel F. Therefore, as shown in FIG. 1, on the upstream side of the solenoid valve 1, the water passage D and the drainage passage F are completely separate systems. Also,
The separate pipes of the water passage D and the drainage passage F are provided in all branch pipes of the shower nozzle C.

According to such an embodiment, when the hot water is drained from the shower nozzle C side, the water supply valve 13 of the solenoid valve 1 is closed and the drain valve 14 is opened. Hot water discharged by this operation flows from the water supply secondary pipe 2 into the water supply secondary passage 15 of the solenoid valve 1, and the water supply 2 of the solenoid valve 1 is discharged.
Water will be discharged from the drain valve 14 on the secondary side to the drain pipe 12, the drain main 3, and the water passage from the solenoid valve 1 to the upstream side (the water supply primary pipe 11 side that is the primary side of the water supply valve 13). It will not flow into D at all. For this reason, since the upstream side from the solenoid valve 1 of the water passage D is exclusively used for water supply, the portion for both water supply and drainage is shortened only by the water supply secondary pipe 2 and the water supply secondary passage 15 of the solenoid valve 1, which is extremely hygienic. In addition, it is possible to contribute to water saving by reducing the amount of drainage.

Further, according to this embodiment, since the drain valve 14 and the drain path F by the drain pipe 12 are connected to each solenoid valve 1 respectively,
Hot water can be discharged from the shower nozzle C other than the shower nozzle C that drains hot water.

[Advantage of the Invention] As described above, in the shower system according to the present invention, the drainage channel dedicated to drainage is arranged from the solenoid valve through the drainage valve provided on the secondary side of the water supply, and the upstream side of the solenoid valve of the waterflow channel Since the side is dedicated to water supply, the portion for both water supply and drainage is shortened, so that the hot water remaining on the shower nozzle side can be drained sanitarily.

Further, since the portion for both water supply and drainage is shortened and the amount of drainage can be reduced, there is an effect that it can contribute to water saving.

Furthermore, because each drain valve is connected to each solenoid valve,
A shower nozzle other than the shower nozzle that drains hot water has an effect that hot water can be discharged.
