Problems solved by technology

[0005] It can be seen that the way of heating water with a plate-exchanged or sleeve-type heat exchanger is secondary heating, so the heating time will be longer, making the user have to wait for the required hot water for a long time, thereby reducing the user's use of hot water. comfort
[0006] In addition, most of the existing water heaters require the user to manually adjust the water flow, or adjust the water temperature by mixing water. This method is very inconvenient and the accuracy is not high, which may cause the water temperature to drop or rise suddenly when bathing or washing hands.

Abstract

The embodiment of the invention provides a water heating method and device. The water heating method comprises the steps that after a starting or water using instruction is received, a draught fan iscontrolled to enter a pre-sweeping state, and a water flow adjusting device is synchronously controlled to adjust a water flow of the water heating device to a preset value; a water inlet temperatureand a water outlet temperature, detected by a temperature sensor in real time, of the water heating device are acquired; an adaptive heating power of the water heating device is determined according to the water outlet temperature, the water inlet temperature and the water flow; and heating control is carried out on water in the water heating device according to the adaptive heating power. According to the method, the temperature rise of the water can be remarkably accelerated, so that the hot water waiting time of a user is shortened, and the water use experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of water heating, in particular to a water heating method and device. Background technique [0002] Existing water heaters, especially water heaters used to heat bathroom water, such as wall-hung boilers, heat water through plate-exchange or casing heat exchangers. [0003] Typically, cold water enters through an inlet at one end of the heater and flows out through an outlet at the other end of the heater after being heated. [0004] For the plate heat exchanger, when there is a demand for hot water, the electric three-way valve will guide the high-temperature water in the main heat exchanger into the plate exchange to heat the cold water. For the casing heat exchanger, the casing is nested in the main heat exchanger, and the flow of water depends on the operation of the water pump. When there is a demand for hot water, the water pump stops working, and the high-temperature water in the main heat exchanger ...
