The central angle of the central line of the plurality of air guiding fins 121 may be selected according to the shape of the partition 112. The sum of the central angle subtended by the central line of the plurality of air guide pieces 121 and the central angle subtended by the partition 112 may be equal to 360 °. For example, when the central angle subtended by the partition 112 is 180 °, the central angle subtended by the center line of the plurality of air guide pieces 121 may be set to 180 °, and further, for example, when the central angle subtended by the partition 112 is set to 270 °, the central angle subtended by the center line of the plurality of air guide pieces 121 may be set to 90 °.

When a user manually selects a "small drying" clothes drying procedure, under the clothes drying procedure, the control system of the clothes treating apparatus may control the switching apparatus 12 to close the inlet of the second air duct 1102, that is, the inlet of the second air duct 1102 is disconnected from the air inlet chamber 1103, and the inlet of the first air duct 1101 is communicated with the air inlet chamber 1103, air in the air inlet chamber 1103 may flow into the first air duct 1101, then air in the air inlet chamber 1103 may not flow into the second air duct 1102 from the first air inlet portion on the first air inlet area of the clothes treating tub, and then air in the air inlet chamber 1103 may not flow into the clothes treating chamber from the second air inlet portion on the second air inlet area of the clothes treating tub, under the clothes drying procedure, the air quantity of the air duct housing assembly 100 introduced into the clothes treating chamber is smaller.

When a user manually selects a "large-sized drying process", under the drying process, the control system of the clothes treating apparatus can control the switching apparatus 12 to open the inlet of the second air duct 1102, that is, the inlet of the second air duct 1102 is communicated with the air inlet chamber 1103, the inlet of the first air duct 1101 is communicated with the air inlet chamber 1103, and air in the air inlet chamber 1103 flows into the first air duct 1101 and the second air duct 1102 respectively, and then enters the clothes treating chamber from the first air inlet portion on the first air inlet area and the second air inlet portion on the second air inlet area of the clothes treating barrel respectively, under the drying process, the air quantity introduced into the clothes treating chamber by the air duct housing assembly 100 is larger.

Of course, the laundry treating apparatus may automatically select a drying course according to the weight of laundry put into the laundry treating chamber. Specifically, the laundry treating apparatus includes a weight detecting device that can detect the weight of laundry put into the laundry treating chamber.

When the control system of the clothes treating apparatus can control the switching apparatus 12 to close the inlet of the second air duct 1102, that is, the inlet of the second air duct 1102 is disconnected from the air intake chamber 1103, and the inlet of the first air duct 1101 is communicated with the air intake chamber 1103, when detecting that the weight of the clothes in the clothes treating chamber is less than the preset weight. Wherein the preset weight may be equal to 0.3 times the rated weight that the laundry treating chamber can withstand.

Under this working condition, because the weight of the clothes in the clothes treatment cavity is smaller, most of the clothes in the clothes treatment cavity can be adhered to the peripheral wall of the clothes treatment cavity when the clothes treatment bucket rotates, and the control system controls the switching device 12 to close the inlet of the second air channel 1102, so that the air in the air inlet cavity 1103 cannot flow into the second air channel 1102, and cannot enter the clothes treatment cavity from the second air inlet part on the second air inlet area of the clothes treatment bucket, the air in the air inlet cavity 1103 can flow into the first air channel 1101, and then enters the clothes treatment cavity from the first air inlet part on the first air inlet area of the clothes treatment bucket, so that the air entering the clothes treatment cavity can exchange heat with the clothes adhered to the peripheral wall of the clothes treatment bucket, thereby being beneficial to improving the clothes drying efficiency, improving the utilization rate of heat in the air and reducing the heat loss in the air.

When the laundry weight in the laundry treatment chamber is detected to be greater than the preset weight, the control system of the laundry treatment apparatus may control the switching apparatus 12 to open the inlet of the second air duct 1102, that is, the inlet of the second air duct 1102 is communicated with the air intake chamber 1103, and the inlet of the first air duct 1101 is communicated with the air intake chamber 1103.

Under this working condition, because the weight of the clothes in the clothes treatment cavity is larger, when the clothes treatment barrel rotates, one part of the clothes in the clothes treatment cavity is attached to the peripheral wall of the clothes treatment barrel, the other part of the clothes is located in the middle of the clothes treatment cavity, and the control system opens the inlet of the second air duct 1102 by controlling the switching device 12, so that the air in the air inlet cavity 1103 flows into the first air duct 1101 and the second air duct 1102 respectively, and then enters the clothes treatment cavity from the first air inlet part on the first air inlet area and the second air inlet part on the second air inlet area of the clothes treatment barrel respectively, and thus the air entering the clothes treatment cavity can exchange heat with the clothes in the clothes treatment cavity, and the clothes drying efficiency is improved.
