Furthermore, the terms "first" and "second" are used only for descriptive purposes and are not intended to have a special meaning.

As shown in fig. 1, the present embodiment provides a clothes treatment apparatus, which mainly refers to a clothes treatment apparatus with a clothes drying function, such as a heat pump clothes dryer, and includes a clothes drying drum 1, a heat pump system and a circulating air system, wherein the clothes drying drum 1 is used for accommodating clothes, the clothes drying drum 1 is provided with an air inlet and an air outlet which are communicated with each other, the circulating air system includes an air duct and a clothes drying fan 2 disposed in the air duct, an inlet of the air duct is communicated with the air outlet of the clothes drying drum 1, an outlet of the air duct is communicated with the air inlet of the clothes drying drum 1, a part of the heat pump system is disposed in the air duct, the heat pump system can process low-temperature humid gas exhausted from the air outlet of the clothes drying drum 1 into high-temperature dry gas under the driving of the clothes drying fan 2 and introduce the high-temperature dry gas into the air inlet of the clothes drying drum 1, so that the high-temperature dry gas is fully mixed with the clothes in the clothes drying drum 1, by means of the continuous air circulation, the drying of the clothes in the drying drum 1 is realized.

Preferably, the clothes drying fan 2 is a centrifugal fan. The centrifugal fan is a machine which can improve the air pressure and discharge air, and can generate better air pressure and air volume. In addition, the centrifugal fan has low noise and high reliability during operation.

Specifically, the heat pump system comprises an evaporator and a condenser which are adjacently arranged, wherein the evaporator and the condenser are both arranged in an air duct, the evaporator can exchange heat with circulating hot humid air inside the evaporator, heat is absorbed from the hot humid air, the hot humid air is cooled, water vapor in the hot humid air is condensed into water, a refrigerant is introduced into the condenser, the refrigerant can release heat in the condenser, and the released heat can heat the circulating gas in the condenser. Therefore, the evaporator can dry the humid air exhausted from the air outlet of the clothes drying roller 1, the condenser can heat the gas exhausted from the evaporator, and therefore the gas in the air channel is enabled to be sequentially dehumidified by the evaporator under the driving of the clothes drying fan 2 to become dry air, heated by the condenser to become hot dry air, and changed into humid air through the inside of the clothes drying roller 1, and then dehumidified by the evaporator to form clothes drying circulation until the clothes are dried.

In addition, as shown in fig. 1, the laundry treating apparatus further includes a motor 3, and the motor 3 can simultaneously drive the drying fan 2 and the drying drum 1 to rotate, so that the drying fan 2 and the drying drum 1 can be driven by only one motor 3, thereby reducing cost. Specifically, the motor 3 is a double-head motor, the double-head motor is provided with an output shaft which rotates in two directions, one end of the output shaft of the double-head motor drives the clothes drying roller 1 to rotate, and the other end of the output shaft of the double-head motor drives the clothes drying fan 2 to rotate.

Because the distance between the clothes drying roller 1 and the motor 3 is long, the belt pulley can realize the transmission of long-distance power. In addition, the belt pulley also has the advantages of smooth operation, low noise and low vibration.

In order to solve the problem of clothes winding, the motor 3 is required to drive the clothes drying roller 1 to rotate forward and backward, and the clothes drying fan 2 also rotates forward and backward along with the motor 3 at the moment. However, when the clothes drying fan 2 rotates reversely along with the motor 3, the clothes drying fan 2 cannot achieve high air pressure and air volume due to the special blades of the clothes drying fan 2, and the reverse air volume of the clothes drying fan 2 is far lower than the forward air volume, so that the clothes drying efficiency is reduced. Although the prior art shows that the motor 3 can drive the clothes drying fan 2 to always keep rotating forwards when the motor 3 drives the clothes drying roller 1 to rotate forwards and backwards, the arrangement mode needs to arrange a reversing device between the motor 3 and the clothes drying fan 2, and the reversing device is complex in structure and inconvenient to operate.
