Digital controlled temp. regulating automatic water tap

Abstract

The invention is a digital controlled temperature adjusting water tap, comprising a main body with cold water inlet, hot water inlet and mixed water cavity, where the mixed water is connected with upper and lower constant temperature water outlets, upper and lower water outlet electromagnetic valves are arranged between the mixed water cavity and the upper and lower constant temperature water outlets, the cold and hot water inlets are respectively connected with digital controlled electric valves with electric motor, the digital controlled electric valves are respectively connected with valve cores of the cold and hot water valves, a temperature sensor is arranged in the mixed water cavity and connected with a drive control MCU with power supply and the MCU is used to control the digital controlled electric valves to control cold and hot water intake quantities so as to implement water temperature adjustment; and its advantages: adopting integrated deign of temperature sensor, drive control MCU, digital controlled electric valves and water temperature display unit to implement automatic water temperature adjustment; the water temperature adjustment course is short, and the error between adjusted and set water temperatures is small; the adjusted water temperature is stable and unable to change with water pressure.

Description

technical field [0001] The invention relates to a faucet. In particular, it relates to a numerically controlled temperature-regulating automatic water faucet which adopts a numerically controlled electric valve to regulate water temperature and automatically discharge water. It is widely used in families, hotels, apartments, hotels and other public bathrooms. Background technique [0002] At present, the constant temperature faucets used in domestic public sanitary places, especially family and hotel bathrooms, etc., all adopt mechanical manual rotary cold water and hot water mixing faucets. People need to test the temperature many times in the process of adjusting the water temperature in use, and it is very inconvenient to adjust the outlet water temperature. At present, there are also various automatic constant temperature faucets on the market, but most of them use thermistor temperature sensing to control the memory spring, and achieve the purpose of constant temperat...

Problems solved by technology

People need to test the temperature many times in the process of adjusting the water temperature during use, and it is very inconvenient to adjust the outlet water temperature.

At present, there are also various automatic constant temperature faucets on the market, but most of them use thermistor temperature sensing to control the memory spring, and achieve the purpose of constant temperature control through mechanical action. Its disadvantage is that the temperature changes with the water pressure.
