Dryers have always been a major energy consumer in washing machines, and the industry has another name for "energy consumption machines". The reason why the dryer becomes a high-energy washing device is that the overall thermal efficiency of the dryer is low. The hot air passing through the heater is not as close as possible to the fabric being dried, and a large portion of the hot air tends to slip away in the gap between the barrel of the machine and the drying basket. This part of the hot air did not participate in the drying, but the outer tube of the machine was baked. Due to the cost factor, the insulation of the dryer is extremely thin, which cannot effectively prevent the heat from being radiated outward, resulting in large environmental heat radiation pollution. In order to solve the above problems, it is necessary to invent a dryer capable of utilizing such heat to improve the heat efficiency of the dryer, save energy, and reduce heat radiation from the machine to the environment.
