Hidden box device

Abstract

The invention relates to a hidden box device. The hidden box device is characterized by comprising a valve seat, a hidden box, an inner rubber plate, an outer rubber plate, a cold water switch assembly, a hot water switch assembly and a water outlet assembly, wherein a cold water inlet, a hot water inlet and a plurality of connecting holes are formed in the valve seat; a first mounting position, asecond mounting position and a third mounting position are arranged on the valve seat; a plurality of water guide holes are formed in the first mounting position, the second mounting position and thethird mounting position; the cold water switch assembly is arranged on the first mounting position, the hot water switch assembly is arranged on the third mounting position, and the water outlet assembly is arranged on the second mounting position; and the valve seat and the inner rubber plate are sequentially arranged in the hidden box, and the outer rubber plate covers the hidden box. Accordingto the hidden box device, the multi-stage waterproof effect can be realized, the situation that the hidden box device leaks can be effectively avoided, the requirements of connecting cold and hot water pipes in different directions can be met, the situation that a pipeline does not correspond to the connecting holes can be avoided, and the installation difficulty of a hidden valve can be prevented from being increased.

Description

technical field [0001] The invention relates to the field of water valves, in particular to a hidden box device. Background technique [0002] At present, many bathrooms are equipped with concealed valves that can realize the mixing of hot and cold water. Among them, this type of installation valve is composed of an embedded box, a water mixing valve core, a valve cover, etc. When hot and cold water are passed into the water mixing valve core, two areas with a large temperature difference will be formed in the embedded box, that is, a cold air area and a hot air area. When the cold air is in contact with the hot air, it is easy to condense, which will produce more water droplets in the embedded box. When the water droplets accumulate to a certain amount, most of them will leak to the wall along the gap between the valve cover and the embedded box, which will easily lead to erosion of the wall. [0003] Simultaneously, because only have a cold water connection and a hot wa...

AI Technical Summary

Problems solved by technology

Since most of the existing hot and cold water pipes are pre-buried in the wall, it often happens that the cold and hot water interface of the concealed valve cannot directly correspond to the hot and cold water pipes, which will easily lead to the difficulty of installing the concealed valve and cause Reduced efficiency of concealed valve installations
