Bathroom cold and hot water constant-temperature device

Abstract

The invention discloses a bathroom cold and hot water constant-temperature device. The bathroom cold and hot water constant-temperature device comprises a valve core, a manual adjusting knob, a motor adjusting knob, a control circuit board and a power supply, wherein the four sides of the valve core are provided with a manual adjusting knob mounting hole, a cold water interface, a motor adjusting knob mounting hole and a hot water interface in sequence; the upper part of the valve core is provided with a warm water outlet; a power supply accommodating groove is formed in the lower part of the valve core; a mixed channel, a cold water channel, a hot water channel and a warm water channel are formed inside the valve core; the manual adjusting knob mounting hole is communicated with the motor adjusting knob mounting hole through the mixing channel; the cold water interface is communicated with the mixing channel through the cold water channel; the hot water interface is communicated with the motor adjusting knob mounting hole through the hot water channel; the manual adjusting knob mounting hole is communicated with the warm water outlet through the warm water channel. By adopting the bathroom cold and hot water constant-temperature device, the technical problems of cold and hot water sealing and flow adjustment can be solved.

Description

technical field [0001] The invention relates to a bathing part, in particular to a bathroom cold and hot water constant temperature device used by people in bathing. Background technique [0002] Existing water heaters generally adjust the outlet water temperature by manually adjusting the ratio of cold and hot water and the outlet water volume. However, this adjustment method is relatively rough, and it is difficult to quickly and accurately reach the desired water temperature, which not only wastes time and water resources, but also has the risk of causing the user to be scalded or catch a cold, which is inconvenient to use. [0003] In recent years, thermostatic valves that use thermosensitive elements as temperature sensors to automatically adjust the opening of cold and hot water valves have appeared. However, due to structural problems, this design will have slow constant temperature speed, and the temperature change caused by water pressure changes. Questions tha...

However, this adjustment method is relatively rough, and it is difficult to quickly and accurately reach the desired water temperature. It not only wastes time and water resources, but also has the risk of causing the user to be scalded or catch a cold, which is inconvenient to use.

[0003] In recent years, thermostatic valves that use thermosensitive elements as temperature sensors to automatically adjust the opening of cold and hot water valves have appeared. However, due to structural problems, this design will have slow constant temperature speed, and the temperature change caused by water pressure changes. Problems that cannot be responded quickly
