Description

  The present invention relates to a stop cock unit and a faucet equipment.

When a stop cock (stop cock mechanism) is arranged on the primary side of the faucet, it is common to arrange a stop cock (stop cock mechanism) for each individual faucet ( Hereinafter, it will be referred to as “conventional example” and refer to FIG.
JP 11-335141 A

  However, this conventional example has the following problems. In other words, when installing a plurality of faucets at a predetermined faucet installation location, the number of stop cocks (stop cock mechanism) increases according to the number of faucets. Cost increases. In particular, when these faucets are hot and cold water mixing faucets, it is necessary to install stop cocks (stop cock mechanisms) on the hot water supply path and the water supply path of each faucet, The installation cost of the faucet is further increased. For example, in the bath unit 90 shown in FIG. 6, when a hot water mixing faucet 95 for a washing place and a hot water mixing faucet 98 for a bathtub are provided side by side, the bus unit 90 includes a total of four stop cocks (water faucets). It is necessary to install (mechanism part) 81-84, and the installation cost of the hot and cold water mixing faucet becomes high.

  In addition, when the number of stop cocks installed in this way increases not only the trouble of faucet construction and maintenance, but also the trouble of construction and maintenance of the stop cock (stop cock mechanism) itself. . Furthermore, when the number of stop cocks (stop cock mechanism parts) increases in installation places where there are few empty spaces, such as the bus unit 90 of an apartment house, these stop cocks (stop cock mechanism parts) are smoothly installed. It is difficult to install.

  The present invention solves the above-described problem, and at a place where a plurality of water faucets are installed, a water faucet unit capable of reducing the number of water faucets (water faucet mechanism part) installed, An object of the present invention is to provide a faucet facility configured using such a faucet unit.

For example, the stop cock unit 50 is incorporated in the faucet equipment S, and hot water supply pressure or water supply pressure is applied to the primary side {that is, the first intermediate flow path portion 55 (second intermediate flow path portion 56)} of the valve body 71a. In addition, when this hot water supply pressure or water supply pressure is applied to the back surface (pressure receiving surface) of the valve main body 71a, the check valve mechanism 70 is opened.

  In the faucet equipment S described above, the passage formed by the internal flow path 50R of the stop cock unit 50 is branched into a plurality of “secondary side flow path portions” in the middle of the path. That is, the passageway has a plurality of “secondary side end portions”, and each “secondary side end portion” has a separate faucet (a faucet 10 for a washing place and a faucet 15 for a bathtub). Can be contacted. That is, since one stop cock (stop cock mechanism 60) can be used with a plurality of faucets 10, 15, when installing a plurality of faucets 10, 15, The number of installed stop cock mechanisms 60) can be reduced.

  Therefore, in the installation location (bus unit 1) where a plurality of faucets (wash faucet 10 and bath faucet 15) are installed, faucets (wash faucet 10 and bath faucet 15) In addition, the installation cost of the stop cock mechanism portions 60 and 60 can be reduced. In addition, it is possible to reduce not only the work and maintenance of the faucet (wash faucet 10 and bathtub faucet 15) but also the work and maintenance of the stop cock mechanism 60 itself. In particular, in the embodiment, a plurality of faucets (a faucet 10 for a washing place and a faucet 15 for a bathtub) are provided by a water stop operation performed on a single stop cock mechanism 60 provided in each stop cock unit. The supply of hot water and water to the water can be stopped, and this is significant in that it enables more efficient construction and maintenance of the faucets (water faucet 10 for washing place and faucet 15 for bathtub). have. Furthermore, since the installation space of the water faucet mechanism 60 can be reduced, the installation can be smoothly performed not only in an installation location with a large empty space but also in an installation location with a small empty space.

  Further, in the present embodiment, not only the stop cock unit is configured as “one faucet related part” centering on the unit main body 50A, but also the check valve mechanism portions 70 and 70 are built in the unit main body 50A. The convenience of the stop cock unit 50 is further improved, and handling of the stop cock unit 50 is facilitated.
