摘要： 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.

摘要： A top load drum washing machine and a positioning device, which relate to laundry washing equipment and which solve problems in the existing technology where a belt is easily worn out by the edge of a groove, which is located on a pulley and which corresponds to a latch bolt of a drum locking device, and where the positional arrangement of the locking device is not flexible enough. For this purpose, the positioning device for use with a top load drum washing machine includes a locking position which is provided on a spoke of a pulley; a locking device which is provided on an outer cylinder, the locking device being provided with a latch bolt; the position of the locking device corresponds to the rotational path of the locking position such that the latch bolt may form a locking fit with the locking position when a drum stops rotating.
