Title:
METHOD AND APPARATUS FOR DEFROSTING WATER HEATER, WATER HEATER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/029594
Kind Code:
A1
Abstract:
The present application relates to the technical field of smart home appliances, and discloses a method for defrosting a water heater. The method comprises: acquiring a defrosting temperature value; when the defrosting temperature value is greater than a temperature threshold, controlling a compressor to operate in a first mode for defrosting; and when the defrosting temperature value is less than or equal to the temperature threshold, controlling the compressor to operate in a second mode for anti-freezing and defrosting. By means of comparing the defrosting temperature value with the temperature threshold, it is determined whether the operation mode of the compressor needs to carry out a defrosting mode for anti-freezing protection. Therefore, by means of setting a high temperature threshold, the operating frequency of the compressor may be adjusted before a heat exchanger freezes, so that the compressor continuously remain in an operating state throughout the entire defrosting process without stopping, thus improving the stability of a system. The present application also discloses an apparatus for defrosting a water heater, the water heater and a storage medium.
