Abstract

The invention discloses a water heater and a thermostatic valve control method and thermostatic valve device. The control method controls the operation of a stepper motor by comparing the outlet water temperature with a target temperature. When the outlet water temperature reaches the target temperature, the current stepper motor's current The real-time position is recorded to the position record variable and overwritten, and when the water heater is started next time, the initial position of the stepper motor is controlled according to the position record variable. The technical solution can realize the control function of the thermostatic valve only by detecting the water outlet temperature of the water heater, and compared with the existing thermostatic valve control solution, the cost is low and the logic control is simple.

Description

technical field [0001] The invention relates to the technical field of water heaters, and more specifically relates to a water heater, a thermostatic valve control method thereof, and a thermostatic valve device. Background technique [0002] Existing water heaters are equipped with thermostatic valves for controlling the mixing ratio of cold and hot water. The traditional water heater is equipped with a mechanical thermostatic valve. The disadvantage of using the mechanical thermostatic valve to realize the constant temperature of the water heater is that it cannot respond to changes in the external environment in a timely manner. [0003] Another type of water heater uses an intelligent thermostatic valve, which can effectively solve the defects of mechanical thermostatic valves. However, this type of thermostatic valve needs to be equipped with a variety of sensors to monitor parameters such as water inlet temperature, inner tank temperature, outlet water temperature, and...
