The washing machine acquires the temperature in the washing drum and a temperature sensor is arranged in the washing drum for real-time detection and acquisition.
In another embodiment, the operating parameters of the washing machine include whether a washing program of the washing machine is executed, and the control system of the washing machine controls the gas power device 4 to be turned on or off according to whether the washing program is executed. Specifically, when the washing program of the washing machine is started to be executed, the control system of the washing machine controls the gas power device 4 to be opened to demist the observation window, and otherwise, the control system of the washing machine controls the gas power device 4 to be closed. When the washing program starts to work, the observation window 3 may be splashed or fogged by the washing water, so that the control system of the washing machine controls the gas circulating pump to start working to demist or remove water drops attached to the observation window 3 in order to prevent the observation window 3 of the washing machine from being fogged, the cleaning of the observation window 3 is ensured, and the use experience of a user is improved. Meanwhile, the control logic for controlling the washing machine is simple and is easier to realize.

Specifically, the washing modes of the washing machine at least include a cold water washing mode, a normal temperature washing mode and a heating washing mode, if the washing mode of the washing machine is the heating washing mode, the control system of the washing machine controls the gas power device 4 to be started for demisting, otherwise, the control system of the washing machine controls the gas power device 4 to stop working. The heating washing mode can cause the temperature difference between the outside of the washing drum and the washing machine to easily cause the fog of the observation window 3, and the temperature in the washing drum is equal to the outside temperature of the washing machine in the cold water mode and the normal temperature mode, so that the fog of the observation window 3 cannot be caused. Therefore, the gas power device 4 of the washing machine is prevented from being started in any washing mode, and the electric energy of the washing machine is prevented from being wasted.
