Abstract

The invention relates to a heating control circuit and a washing machine. The heating control circuit comprises a gate control circuit and at least two heating circuits; each heating circuit is connected with the gate control circuit; the gate control circuit is used for performing alternative gate control on the heating circuits. According to the heating control circuit and the washing machine, the plurality of heating circuits do not need to work simultaneously and accordingly damage to a device due to too large loads is avoided, the safety hidden trouble is eliminated, and the safety performance of the device such as the washing machine which is provided with at least two heating circuits is improved.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a heating control circuit and a washing machine. Background technique [0002] At present, drum washing machines generally have two functions of water heating and air drying heating. The water heating circuit is used for heating the washing water of the washing machine, and the air-drying heating circuit is used for air-drying and heating the clothes and / or the washing drum. [0003] Under the normal operation of the washing machine, the water heating circuit and the wind heating circuit will not operate at the same time. If the two heating circuits operate at the same time due to abnormal settings of the washing machine, etc., a large operating current may be generated, which may damage the machine and pose a safety hazard. However, the prior art still lacks a corresponding security solution. Contents of the invention [0004] A brief overview of the invention is ...
