Concealed and embedded lower main body

Abstract

The invention discloses a concealed and embedded lower main body. The concealed and embedded lower main body is provided with a cold water inlet flow passage, a hot water inlet flow passage, a mixed water flow passage and at least one water outlet flow passage. The cold water inlet flow passage, the hot water inlet flow passage, the mixed water flow passage and the water outlet flow passage are respectively provided with an inlet and an outlet. Cold water flows to a first control valve through the cold water inlet flow passage, hot water flows to the first control valve through the hot water inlet flow passage, the cold water and the hot water meet at the first control valve, then mixed water is fed into the mixed water flow passage and finally the mixed water flow passage is communicated with the water outlet flow passage through a second control valve. By arranging the mixed water flow passage, a water path of a main control system of an upper main body which is matched with the lower main body becomes simple, the height of the upper main body is reduced, the cost is saved, the overall installation depth of the product is reduced, the situation that the lower main body cannot be installed due to limitation of wall depth is avoided and the installation becomes simple; since the overall installation depth of the product is reduced, the concealed and embedded lower main body can meet the demands of hollow walls of wood structure buildings in different countries and regions.

Description

technical field [0001] The invention relates to a concealed pre-embedded lower body. Background technique [0002] During the construction of the house, the waterway system needs to be embedded in advance, that is, the water pipes must be buried in the wall before the decoration, and the water pipes need to leave the connection part exposed outside the wall. When decorating, the water outlet device can be directly connected with the connecting part of the water pipe. [0003] However, the connection parts of the water pipes in the traditional waterway system are exposed outside, which takes up space, affects the visual effect, and is easy to age. Contents of the invention [0004] The invention provides a concealed pre-embedded main body, which overcomes the shortcomings of the background technology. The technical solution adopted by the present invention to solve its technical problems is: [0005] A concealed pre-buried lower body, provided with a cold water inlet cha...
