Description

Cleaning machine and control method thereof Technical Field The invention relates to the technical field of household appliances, in particular to a cleaning machine and a control method thereof. Background After the tableware and/or kitchen ware is washed by the washing machine, a large amount of water is still adhered to the tableware and/or kitchen ware, so that the tableware and/or kitchen ware needs to be dried, and the possibility of bacterial growth in the later period is reduced. At present, two drying modes of the cleaning machine are generally adopted, one is that air is directly discharged after hot air drying, and the other is that the hot air drying adopts a crystal bud mode to dehumidify the air. For direct discharge after the hot-blast stoving, the wet and hot gas that hot-blast stoving formed is discharged indoor after simple condensation, and the gas vent of cleaning machine can have a large amount of steam, and can form the comdenstion water at cupboard and ground, can cause inconvenience to the user, influences user experience. For adopting the crystal bud mode to dehumidify the wind, the wet and hot gas formed by hot air drying is dehumidified through the crystal bud in the cleaning machine, and the gas after the moisture absorption can be continuously input into the washing cavity for recycling, but the type of cleaning machine has relatively complex structure and higher cost.
