Problems solved by technology

However, in actual use, the heating capacity of the heating device fluctuates greatly due to the influence of the power supply current, which makes the water temperature of the heating output fluctuate greatly. Only rely on the constant temperature shower head to adjust the hot water and cold water to meet the constant temperature output hot water less effective, resulting in poor user experience

Abstract

The invention discloses a control method of an electric water heater. The electric water heater comprises a heating container, first electric heating sub-components, second electric heating sub-components, a power storage module, a discharge control module and an external power supply discharge module. The control method comprises the steps that in the process that water flowing through the heating container is heated through the second electric heating sub-components, if the second electric heating sub-components are at the maximum heating power and the water outlet temperature of the heatingcontainer is lower than the set temperature, the discharge control module controls the corresponding first electric heating sub-components to be powered on, and the first electric heating sub-components heat water flowing through the heating container at the same time. Constant-temperature hot water output is achieved so as to reduce the fluctuation range of output water temperature and improve user experience.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a control method for an electric water heater. Background technique [0002] At present, water heaters are household appliances commonly used in people's daily life. Among them, electric water heaters are widely used because of their small size, and instant water heaters with instant heating function are used by more users because of their convenience. However, due to the current limitation of household electric wires, the power of instant water heaters is relatively low, which cannot meet the user's requirements for large-flow bathing. Chinese patent application number 201811467936.X discloses a small-power battery energy storage low-voltage electric instantaneous heating constant temperature electric water heater system, that is, a battery pack is used as an electric heating device to provide electric energy for heating to realize instant water supply, ...
