Technical Field

The invention belongs to the field of washing machines, and particularly relates to a washing and drying integrated washing machine and a drying method thereof.

Background

Washing machines are largely classified into pulsator type, pulsator type and drum type washing machines. The pulsator type washing machine performs a washing operation by rotating a pulsator at the center of a washing tub left and right. The agitator type washing machine performs a washing operation using a frictional force between water current and laundry by rotating a rotary blade at the center of a washing tub in the left-right direction. The drum type washing machine performs a washing operation by beating laundry by rotating a drum.

An outer tub and an inner tub are provided in a cabinet of a washing machine, and the inner tub is an important part of washing, and generally, a hole is provided in a tub wall for introducing washing water into the inner tub or for dehydrating laundry in the inner tub. A large amount of dirt and bacteria are bred between the inner barrel and the outer barrel due to the long-time flowing and accumulation of the washing water, secondary pollution is generated to clothes, and the washing machine is not beneficial to the health of a human body, so that the washing machine with the imporous inner barrel is provided.

Along with the improvement of the living standard and the taste of residents, the existing washing machine not only needs to meet the washing requirement, but also needs to meet the drying requirement after the clothes are washed, so how to dry the washing machine provided with the non-porous inner cylinder is set as a hotspot for research and development.

The Chinese patent with the application number of 201410708103.3 discloses a water-saving drum washing machine, which comprises an outer drum, an inner drum arranged in the outer drum and a drying air path communicated with the inner drum, wherein the inner drum and the outer drum are coaxially arranged on a central shaft, the inner drum is a hole-free inner drum, and a plurality of lifting devices are arranged on the inner wall of an inner hole; the drying air path and the lifting device are respectively communicated with the hollow structure, and the lifting device is provided with a plurality of water outlets. When the drying program is started, the drying fan is started to uniformly blow hot air to the clothes through the drying air path, the hollow structure, the connecting pipeline, the lifting device and the water outlet, but the drainage pipeline and the drying air path in the patent are both connected with the hollow structure 6, the corresponding program is switched through the electromagnetic valve, the electromagnetic valve needs to be switched continuously when the drying air enters and exits the inner cylinder, air inlet and air exhaust cannot be carried out simultaneously, and the quick drying of the clothes is not facilitated.
