The heat pump type clothes dryer on the market performs well and can dry clothes in a low temperature environment of 50-60℃. In principle, high-temperature and low-humidity air is formed after condenser treatment, the air is sent to the bottom of the drying drum through the back air duct assembly, and the clothes are dehumidified. The high-temperature and high-humidity air after dehumidification is sent back to the evaporator from the drying drum port, and low-temperature and low-humidity air is formed after the evaporator treatment, and then the condenser realizes circulation. The current common clothes dryer is sent by the rear side of the drying drum, and generally, the bottom of the drying drum is provided with a 360° array of air supply holes, and the air supply hole accounts for only 8-12% of the area of the drum bottom, which seriously reduces the heat exchange efficiency. Increasing the number of air supply holes will weaken the strength of the drying drum. In addition, in the drying process, the cylinder body rotates continuously, and the air supply holes at the bottom of the cylinder body also rotate continuously. When the gas enters the cylinder body from the rear side of the cylinder body, the gas is continuously cut by the rear cover, causing the gas flow to be blocked, and the heat loss is large, and the drying efficiency is low.

The two ends of the heat exchange and dehumidification air duct 120 are respectively communicated with the air inlet air duct 140 and the air outlet air duct 130 to form a circulating air path of the air inlet air duct 140, the treatment cavity 111, the air outlet air duct 130 and the heat exchange and dehumidification air duct 120. The heat exchange and dehumidification air duct 120 is provided with an evaporator 121 and a condenser 122 arranged in sequence along the direction of gas flow, the evaporator 121 is arranged at the rear side of the condenser 122, the air inlet air duct 140, the heat exchange and dehumidification air duct 120 or the air outlet air duct 130 is provided with a driving member 123, the driving member 123 is controlled to rotate to push the gas to flow continuously in the circulating air path, and the gas flows from the air inlet air duct 130 to the treatment cavity 111, and then flows from the air outlet air duct 130 to the heat exchange and dehumidification air duct.

[0054] The laundry treatment device 100 of the embodiment can include a cylinder 110, an air inlet duct 140 arranged at the front side of the cylinder 110, an air outlet duct 130 arranged at the rear side of the cylinder 110, and a heat exchange and dehumidification air duct 120, the air inlet duct 140, the treatment cavity 111, the air outlet duct 130, and the heat exchange and dehumidification air duct 120 forming a circulating air path, and a driving member 123 controlled to push the gas to flow continuously in the circulating loop, so that the gas can continuously flow from the air inlet duct 140 at the front side of the cylinder 110, through the cylinder 110, and then from the air outlet duct 130 at the rear side of the cylinder 110, into the heat exchange and dehumidification air duct 120 for heat exchange and dehumidification, and then further circulate. Since the air inlet duct 140 of the embodiment is arranged at the front side of the cylinder 110, the gas can directly enter the cylinder 110 from the air inlet duct 140, and there is no any obstruction at the inlet, and the gas is not affected by other components, so that the backflow phenomenon is avoided, the air volume entering the cylinder 110 is increased, the heat loss is reduced, the drying rate of the laundry is accelerated, and the efficiency of the laundry treatment is improved.

[0055] In addition, since the gas in the cylinder 110 flows out from the air outlet duct 130 at the rear side of the cylinder 110, generally, there are components blocking the rear side of the cylinder 110, so that the gas is blocked, the air volume is reduced, the gas stays in the cylinder 110 for a longer time, and then the contact time between the gas and the laundry is increased, and then the heat exchange efficiency is further improved.

[0056] Specifically, the driving member 123 in the embodiment can be an impeller or a component similar to the impeller. The driving member 123 can be controlled to rotate, and then push the gas in the air duct to flow.

[0057] As a specific embodiment of the utility model, the driving member 123 of the embodiment is arranged in the heat exchange and dehumidification air duct 120, and is located at the position of the heat exchange and dehumidification air duct 120 close to the air outlet duct 130, the driving member 123 is controlled to rotate to push the gas to flow through the heat exchange and dehumidification air duct 120, the air inlet duct 140, the cylinder 110, and the air outlet duct 130.

[0058] In the embodiment, the driving member 123 is arranged in the heat exchange and dehumidification air duct 120, when the driving member 123 is controlled to rotate, the gas flow in the air duct can be pushed, and then the gas in the cylinder body 110 and the gas in the heat exchange and dehumidification air duct 120 are continuously circulated. When the high-temperature and high-humidity gas in the cylinder body 110 flows through the heat exchange and dehumidification air duct 120, the gas is cooled by the evaporator 121 to condense and remove the humidity in the gas. The dry gas is heated by the condenser 122 to form hot gas, and then flows to the cylinder body 110. The hot gas contacts the clothes in the cylinder body 110 to heat the clothes and remove the humidity on the clothes. At this time, the gas becomes hot and humid and enters the heat exchange and dehumidification air duct 120 for drying, and the circulation is repeated. The flow of the gas pushed by the driving member 123 can increase the processing efficiency of the clothes in the cylinder body 110.

[0059] As a specific embodiment of the utility model, the driving member 123 of the embodiment is arranged at the air inlet duct 140, and the driving member 123 is controlled to rotate to push the gas to circulate through the air inlet duct 140, the processing cavity 111, the air outlet duct 130 and the heat exchange and dehumidification air duct 120.

[0060] The driving member 123 of the embodiment is arranged at the air inlet duct 140, which can push the gas to circulate in the circulating air path and directly blow the gas from the air inlet duct 140 to the cylinder body 110. Compared with arranging the driving member 123 at the rear part of the heat exchange and dehumidification air duct 120, arranging the driving member 123 at the air inlet duct 140 can further improve the efficiency of clothes processing.

[0061] As a specific embodiment of the utility model, as shown in Figure 3 , Figure 4 and Figure 5 , the clothes processing device 100 of the embodiment can further include a base 150 arranged below the cylinder body 110, and the heat exchange and dehumidification air duct 120 is located in the base 150.

The motor 151 can include a first output shaft 152 penetrating the side wall forming the heat exchange and dehumidification air duct 120 and connected with the driving member 123 to drive the driving member 123 to rotate.

[0062] Specifically, the base 150 of the embodiment includes a cover plate (not shown in the figure), which forms a sealed cavity inside the base 150. The air duct is arranged in the cavity, and the motor 151 is also arranged in the cavity, but the motor 151 is located at the side of the air duct. The driving member 123 is driven by the motor 151. The output shaft of the motor 151 can penetrate the side wall forming the air duct and enter the air duct to connect with the driving member 123, and then drive the driving member 123 to rotate.

[0063] The base 150 of the embodiment can further comprise a compressor 153, which is located outside the heat exchange and dehumidification air duct 120 and communicates with the evaporator 121 and the condenser 122 through a pipeline penetrating through the side wall of the heat exchange and dehumidification air duct 120.

[0064] Specifically, the compressor 153 is connected with the evaporator 121 and the condenser 122 through copper pipes penetrating through the side wall of the air duct to form a heat pump system. The working principle of the specific heat pump system is that the compressor 153 generates refrigerant after working, the refrigerant is transmitted to the evaporator 121 and is converted from liquid state to gaseous state at the evaporator 121, and then heat absorption is performed, so that the temperature outside the evaporator 121 is reduced, the hot and humid gas outside is cooled, and the humidity is condensed at the evaporator 121 to discharge cold waste water. The refrigerant generated by the compressor 153 is transmitted to the condenser 122, the condenser 122 compresses the refrigerant and releases heat, and the gas passing through the evaporator 121 forms hot gas after passing through the condenser 122.

[0065] Specifically, the heat exchange and dehumidification air duct 120 extends along a preset direction, the motor 151 and the compressor 153 are arranged side by side in the preset direction, and the motor 151 and the compressor 153 are arranged on the side edges in the direction perpendicular to the preset direction of the air duct, wherein the preset direction is parallel to the axial direction of the cylinder body 110.

[0066] Specifically, the motor 151 and the compressor 153 of the embodiment are arranged side by side in front of and behind each other and are arranged on the side edges of the air duct, so as to ensure normal operation of the entire clothes treatment device 100, reasonable layout of the motor 151 and the compressor 153, improve the utilization rate of space, and improve the heat exchange efficiency.

[0068] Specifically, the motor 151 of the embodiment can comprise a second output shaft 154, which drives the cylinder body 110 to rotate through a belt when rotating, so that one motor 151 can drive the driving member 123 to rotate and also drive the cylinder body 110 to rotate, without the need to additionally increase the motor 151, thereby reducing the occupied space.

[0069] As a specific embodiment of the utility model, Figure 4As shown, the clothes treatment device 100 of the embodiment can further include a first support 160 connected to the front side of the base 150 and extending to the front side of the drum 110 to support the front side of the drum 110, and the air inlet duct 140 is arranged in the first support 160.

[0070] Specifically, the first support 160 of the embodiment is provided with a circular drop port 161 which communicates with the treatment cavity 111 of the drum 110.

[0071] Specifically, in the prior art, since the gas enters the drum 110 from the rear side of the drum 110 and flows out from the front side, a filtering device is arranged at the front side of the drum 110, so that the structure of the drop port cannot be circular, which causes the structure of the drop port to be not completely matched with the drum 110, and further causes the clothes to be inconvenient to drop.

[0072] In the embodiment, since the drop port 161 does not need to be provided with a filtering device, the first support 160 can be provided with a circular drop port 161 which can be completely matched with the drum 110, and the area of the drop port 161 is larger, so that the clothes are more convenient to drop.

[0098] More specifically, the clamping structure 186 of the embodiment can include a clasp 187 and a clamping groove 188. The clasp 187 is arranged at the connecting part 184 and located at a position opposite to the rotating connection position. The clamping groove 188 is arranged at the rib 185, and the cooperation between the clamping groove 188 and the clasp 187 enables the connecting part 184 to be buckled and opened relative to the rib 185.

[0099] Specifically, when the connecting part 184 is buckled with the rib, the clasp 187 is clamped in the clamping groove 188. When it is necessary to open the connecting part 184 for cleaning the hair dust, the clasp 187 is pressed to be separated from the clamping groove 188, so that the connecting part 184 can be opened. Of course, as other embodiments, the positions of the clasp 187 and the clamping groove 188 can be exchanged, that is, the clasp 187 is arranged at the rib 185, and the clamping groove 188 is arranged at the connecting part 184.
