Abstract

The invention discloses a control method and a control device of a water heater, wherein the control method of the water heater comprises the following steps: distinguishing biological characteristics of an current water heater user; obtaining the historical outlet water temperature when the user uses the water heater according to the distinguished biological characteristics of the current water heater user; detecting the current hot water temperature and the current cold water temperature of the water heater; determining the target openness of the proportional valve according to the historical outlet water temperature, the current hot water temperature and the current cold water temperature, wherein the proportional valve is used for mixing cold and hot water; and controlling the current outlet water state when the user uses the water heater according to the target openness of the proportional valve, wherein the current water outlet state comprises the current water outlet flow rate and / or the current outlet water temperature. The control method and the control device can be used for solving the problem that the outlet water with high water temperature precision cannot be provided based on different users when the water heater is used in the associated technology is solved.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a control method and device for the water heater. Background technique [0002] At present, in related technologies, when users use the water heater, they often need to manually adjust the opening of the proportional valve for mixing cold and hot water to adjust the outlet water temperature so that the outlet water temperature is a comfortable temperature for human body. Wherein, the aforementioned water heaters include: gas water heaters, electric water heaters, solar water heaters and air energy water heaters (also known as air energy heat pump water heaters). Among them, at the cost of consuming part of the electric energy, the air energy water heater excavates and utilizes the energy (heat) stored in the air through a thermal cycle to produce hot water. Compared with traditional water heaters (such as gas water heaters, electric water heaters, and solar water heaters), air-energ...
