Abstract

The invention relates to an electric water heater which comprises a heating device and a control system. The control system is used for controlling the power of the heating device, and the electric water heater further comprises a flow sensor, a temperature sensor and a calculating device, wherein the flow sensor is used for detecting water flow entering the heating device, the temperature sensor is used for detecting the temperature of inlet water entering the heating device, and the calculating device can calculate the heating power of the heating device according to the temperature difference of the inlet water and outlet water, the water flow and other parameters. The invention additionally relates to a control method of the electric water heater.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an intelligent constant-temperature instantaneous electric water heater. In addition, the invention also relates to a control method of the electric water heater. technical background [0002] The instant electric water heater is a water heater that can quickly heat the flowing water through electronic heating components, and can control the water temperature, flow rate, power, etc. through the circuit, so that the water temperature can reach the temperature suitable for human body bathing. Instant heating, no need to wait, usually can start heating within seconds. [0003] The constant temperature instant electric water heater refers to the electric water heater that can keep the outlet water temperature basically constant with the temperature set by the user even when the water inlet flow rate, the inlet water temperature and the power supply voltage change. [0004] The disadvanta...
