Description
Technical Field
The invention relates to the technical field of dish washer control, in particular to a dish washer control method and device.
Background
As living conditions become better, more and more users install dish washers. The door is not opened during the washing process due to the missing of the dishes and the like when the dishwasher is used. When the door is closed again for washing, cold air entering through the door is heated and expanded by hot water quickly, and redundant air is not discharged from the air outlet, so that air pressure is generated to push the door body. Therefore, the high-temperature hot water possibly causes danger to a user in the moment of opening the door, and meanwhile, the controller judges that the dish washer is in the state of opening the door, the washing process is suspended, and finally washing cannot be completed, so that the user experience is affected, complaint and repair are increased, and after-sale expense is increased.
At present, when the dish washing machine is in a washing stage, if the door state of the dish washing machine is detected to be changed from an open state to a closed state, the current water temperature of the liner chassis of the liner in the dish washing machine is detected and judged; if the current water temperature of the liner chassis is judged to be greater than the preset temperature, the dish washer is controlled to intermittently wash according to a preset washing sequence, and the dish washer is controlled to wash in a normal washing mode after the preset washing sequence is executed. However, the intermittent sequential washing mode cannot completely ensure that the door is not lifted or the pause time is too long, thereby affecting the user experience.
