Description

Technical Field

[0001] The utility model relates to the technical field of clothes drying, in particular to a clothes drying machine with hot air circulation. Background Art

[0002] After washing, clothes need to be aired to dry. However, due to some environmental factors, such as excessive humidity in the air or rainy weather, the washed clothes will remain wet for a long time and cannot be used. At this time, some drying equipment is needed to dry the clothes. Some hot air circulation dryers have multiple drying trays installed inside the device, so that the device can dry multiple pieces of clothes at the same time. When in use, first put the clothes into the drying tray, then close the closing door, and then use the control element to make the dehumidification fan run to extract and dehumidify the gas at the upper end of the device. Then, the dry gas passes through the pipeline and is heated by the heating device and discharged from the exhaust hole on the bottom wall of the device. The hot air moves from bottom to top inside the device, thereby heating and drying the clothes. However, due to seasonal environmental conditions, the size and thickness of the clothes themselves are different, and the drying space they occupy is different. The space above the drying tray of the device is fixed, and the drying space of the clothes cannot be reasonably adjusted according to the needs, which is inconvenient to use. At the same time, the drying temperature of the clothes inside the device is fixed. Different clothes are limited by their own materials and the most effective heating temperature is different.
