Description

Condensation anti-back suction washing and drying machine

Technical field

The present disclosure relates to the technical field of a washing and drying machine, for example, to a washing and drying machine for condensing anti-back suction.

Background technique

With the development of science and technology and the improvement of economic level, more and more users began to pay attention to and choose the washing and drying machine. As shown in Figure 1, the drying process of the washing and drying machine is mainly the heating of the drying heating tube. The heat, the drying fan blows the heat generated by the drying heating pipe into the inner cylinder through the drying heating passage, and the heat causes the water of the laundry to evaporate into steam, and the moist hot steam enters the condenser to be condensed into water.

In the drying process of the relevant washing and drying machine and the dryer, there are mainly three kinds of condensation methods for the hot and humid steam: the first is to use the cold water of the tap water to condense the moist heat steam; the second is to use the compressor and apply the compressor principle. The refrigerant condenses the hot and humid steam; the third is an air heat exchanger that condenses the hot and humid steam using the outside air.

In the drying process, the wet heat steam is condensed in the condenser to form water droplets. A part of the water droplets are blown by the fan toward the inner wall of the condenser and flow down the inner wall. Due to the large volume of air, there is still a part. The water droplets are directly carried into the drying fan, blown onto the heating pipe, or even directly into the inner cylinder, which has an effect on the drying efficiency.
