Abstract
A clothes drying device, including an air channel, an air path switching assembly, multiple clothes drying apparatuses, and multiple heating apparatuses. The air path switching assembly includes a first multi-position switching component and a second multi-position switching component. The first multi-position switching component and the second multi-position switching component are respectively provided between a hot air input section and intermediate heat source sections and between a hot air output section and the intermediate heat source sections; the first multi-position switching component and the second multi-position switching component have the same number of switching positions and are configured to work in conjunction to each other so that at least one clothes drying apparatus is selectively communicated with the corresponding hot air input section, the hot air output section, and the intermediate heat source sections so as to form a circulation loop.
