Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for distributing water or hot water to a plurality of devices in various water supply systems.

[0002]

2. Description of the Related Art For example, in a conventional solar system, as shown in FIG. 7, water from a water supply source passes through a main plug 31, a pressure reducing check valve 32, a water supply plug 33, a check valve 34, and a water supply hose 35. It is supplied to the solar water heater 36. Solar water heater 3
The water warmed in 6 is supplied to the water heater 41 through the reflux hose 37, the mixing valve 38, the check valve 39, and the three-way valve 40.

The outlet of the water tap 33 is connected to a mixing valve 38 through a pipe 42, and the hot water from the solar water heater 36 and the water from the water tap 33 are mixed at an arbitrary ratio by the mixing valve 38. The outlet of the main tap 31 is connected to a three-way valve 40 via a pipe 43 and a check valve 44. By switching the three-way valve 40, it is possible to selectively supply mixed water or water to the water heater 41. .

[0004]

However, according to the conventional solar system, since many valves and piping are connected at the construction site, procurement and management of parts are troublesome, and connection work is very troublesome. Not only that, but there was also the problem that connection mistakes tended to occur.

Therefore, an object of the present invention is to provide a water supply distribution device in which the valves and pipes necessary for the water supply system are unitized and can be easily incorporated in the system.

[0006]

In order to solve the above-mentioned problems, a water supply distribution device of the present invention comprises a valve unit in which a plurality of valves required for a water supply system are connected by piping to form the valve unit. The housing is housed inside the housing, and the operation portion of the valve and the connection port of the pipe are provided outside the housing.

[0007]

The distributor of the present invention is carried into the construction site as a single item, and is incorporated in the water supply system by connecting the connection port to another device. In this case, since a plurality of valves and pipes are connected in advance, the number of connection points on the site is reduced, the work is simplified, and connection mistakes are less likely to occur.
