Technical Field

The invention belongs to the field of clothes treatment equipment, and particularly relates to a washing machine with a drying function.

Background

In order to facilitate the user to dry the clothes as soon as possible, the existing washing machine is added with a drying function. The drying device for realizing the drying function can adopt a heating mode of heating air by a heater or adopt a heat pump system to enhance the cyclic utilization of heat. Whether the clothes are dried by heating through a heater or by a heat pump system, hot air is generally fed from the front part of an outer cylinder of a washing machine or a window pad of the outer cylinder, the hot air is fed into the inner cylinder to exchange heat with damp clothes, the damp and cooled air is led out from an air outlet at the rear part of the outer cylinder or is condensed to remove humidity and then is heated to continuously dry the clothes.

For the inner and outer drum structure of the existing drum washing machine, a gap is formed between the inner drum and the outer drum in the radial direction, and a gap is also formed between the inner drum and the outer drum in the axial direction. When the washing of the washing machine is finished, the drying device starts to operate, the drying device generates hot air, the hot air enters the inner cylinder and the outer cylinder from the front part of the outer cylinder, however, because a large gap exists between the outer cylinder and the inner cylinder, and clothes only exist in the inner cylinder and do not exist between the inner cylinder and the outer cylinder, the hot air can also flow between the inner cylinder and the outer cylinder. The hot air passing through the inner cylinder and the outer cylinder can cause resource waste, thereby not only greatly reducing the drying efficiency, but also increasing the power consumption cost.

The present invention has been made in view of this situation.
