[0027] For reference Figures 1-5 As shown in the figure, a clothes processing device includes a condensing assembly and a heating assembly, the condensing assembly includes a first condensing structure 1 and a second condensing structure, the first condensing structure 1 is used for one-stage condensation of moist hot air; the second condensing structure is used for two-stage condensation of air after one-stage condensation; the heating assembly includes a heating channel; the moist hot air can flow through the first condensing structure 1, the second condensing structure and the heating channel in sequence. The present application adds a first condensing structure 1 between the air in the cylinder and the heat pump system, and first condenses part of the moist hot air in the first condensing structure 1, and then enters the heat pump system, thereby shortening the drying time and improving the drying efficiency.

[0028] The present application also discloses some embodiments, and the clothes processing device further includes a rear cylinder structure 2; the first condensing structure 1 is arranged on the outer side of the rear cylinder structure 2; the first condensing structure 1 is provided with a first condensing channel; the rear cylinder structure 2 is provided with a moist hot air duct; the moist hot air duct is in communication with the first condensing channel; and the first condensing channel is connected with the second condensing structure. The present application shortens the drying time, improves the drying efficiency and improves the user's use experience.

[0029] The present application also discloses some embodiments, and the first condensing channel is an annular channel.

[0030] The first condensing structure 1 of the present application is a condensing ring; the appearance structure of the condensing ring is in a ring shape, and the inside is hollow to serve as a first condensing channel for air condensation; a direct drive motor drives the drum to rotate for washing, and the position of the motor is in the inner ring of the condensing ring.

[0031] The present application also discloses some embodiments, and the first condensing structure 1 is provided with a water outlet 13; the water outlet 13 is used for guiding the condensate water in the first condensing channel to drain out.

[0032] This application also discloses several embodiments. The rear cylinder structure 2 is provided with multiple axial reinforcing ribs, which are arranged sequentially along the axial direction of the rear cylinder structure 2. A first condensing structure 1 is installed at the first end of each axial reinforcing rib. The first ends of each axial reinforcing rib are located on the same plane; that is, the back of the rear cylinder structure 2 has multiple reinforcing ribs, the tops of which are on the same plane, coinciding with the front surface of the condensing ring. The reinforcing ribs prevent deformation of the rear cylinder and also provide support for the condensing ring. The axial reinforcing ribs extend axially along the rear cylinder structure, and the first ends of the axial reinforcing ribs are higher than the outermost ring of the rear cylinder structure. The surface of the first condensing structure closest to the rear cylinder is in contact with the first end of the axial reinforcing rib. The condensing ring is installed on a screw post by screws, and the end face of the screw post and the first end of the reinforcing rib are located on the same plane, thus the condensing ring is in contact with the first ends of each axial reinforcing rib.

[0033] Besides the front surface of the condensing ring coinciding with the top surface of the reinforcing rib, the large gaps between the reinforcing ribs ensure the heat exchange area of ​​the outer wall of the condensing ring. This prevents the temperature difference between the inside and outside of the air duct of the first condensing structure 1 from decreasing after prolonged drying, thus avoiding insufficient condensation of water vapor by the air in the air duct. After initial condensation, the humid and hot air in the first condensing structure 1 mixes with the air at the outlet 23. The outlet 23 is connected to the heat pump system, and the air enters the heat pump components. The heat pump system further converts the humid and hot air into dry and hot air, which then re-enters the cylinder for circulation. The condensate in the ring of the first condensing structure 1 is discharged through the drain outlet 13.

[0034] This application also discloses some embodiments, wherein at least one first air guide 21 is provided on the rear cylinder structure 2; the first air guide 21 connects the hot and humid air duct and the first condensation channel;

[0035] This application also discloses some embodiments, in which a second air guide 22 is provided on the rear cylinder structure 2; the second air guide 22 connects the heating channel and the first condensation channel.

[0036] This application also discloses several embodiments. The first condensation structure 1 is provided with an inlet 11, which connects to a first condensation channel. The inlet 11 guides hot and humid gas into the first condensation channel. When the rear cylinder structure 2 is also provided with at least one first air guide port 21, the inlet 11 and the first air guide port 21 are sealed together. This application also includes a sealing structure 3, which is disposed between the inlet 11 and the first air guide port 21. The sealing structure 3 is a sealing ring. A protruding annular structure is provided at the inlet 11, and the sealing ring is disposed on the inner or outer peripheral wall of the annular structure. An annular groove extending circumferentially around the inlet 11 can be provided on the inner or outer peripheral wall of the annular structure; the sealing ring is disposed within the annular groove.

[0037] The inlet 11 on the first condensing structure 1 can be one or more, and its shape can be circular or fan-shaped. Its position is not limited to the bottom and can be at any position on the ring.

[0038] This application also discloses some embodiments. An outlet 12 is provided on the first condensing structure 1, and the outlet 12 is connected to the first condensing channel. The outlet 12 is used to guide the gas out of the first condensing channel. When a second air guide 22 is also provided on the rear cylinder structure 2, the outlet 12 and the second air guide 22 are sealed together. This application also includes a sealing structure 3. The sealing structure 3 is disposed between the outlet 12 and the second air guide 22; the sealing structure 3 is also a sealing ring; a protruding annular structure is provided at the outlet 12, and the sealing ring is disposed on the inner or outer peripheral wall of the annular structure. An annular groove extending circumferentially around the inlet 11 can be provided on the inner or outer peripheral wall of the annular structure; the sealing ring is disposed in the annular groove. The interior of the first condensing structure 1 has a cavity, and gas enters from the inlet 11 and exits from the outlet 12. Its condensation principle is as follows: when hot and humid air enters the cavity of the condensing ring, i.e., the first condensing channel, a temperature difference is formed between the first condensing channel and the outside air. Heat exchange occurs between the condensing ring and the outside through the outer wall of the condensing ring, achieving primary condensation.

[0039] That is, both of the above-mentioned sealing structures 3 are sealing rings; during the installation process, the two sealing rings are first installed in the annular grooves at the outlet 12 and the inlet 11 respectively. Then, the outlet 12 is aligned with the second air guide 22 and the inlet 11 is aligned with the first air guide 21. At this time, the condensing ring is installed on the rear cylinder structure 2. Then, the fastening structure 4, such as a screw, passes through the screw hole on the condensing ring and is fixed on the screw post on the rear cylinder structure 2, so that the condensing ring is tightly fixed to the back of the rear cylinder structure 2.

[0040] This application also discloses some embodiments, in which an air outlet 23 is provided on the rear cylinder structure 2; the air outlet 23 is connected to the humid and hot air duct; when a second air guide 22 is also provided on the rear cylinder structure 2, the second air guide 22 is connected to the air outlet 23; the second air guide 22 can guide the air in the first condensation channel into the air outlet 23, mix with the humid and hot gas discharged from the humid and hot air duct at the air outlet 23, and then enter the second condensation structure through the air outlet 23. This application adds an external first condensation structure 1, which can perform primary condensation treatment on part or all of the air, reduce the pressure of the heat pump system, improve drying efficiency and drying time, and is also more energy-efficient.

[0041] In the absence of air outlet 23, the outlet 12 of the first condensing structure 1 is connected to the heat pump system. All the humid and hot air inside the cylinder enters the first condensing channel through the inlet 11 of the first condensing structure 1 and then enters the heat pump system through the outlet 12 for further drying. At this time, all the air can undergo primary condensation treatment. When there is air outlet 23, a portion of the humid and hot air is directly discharged into the heat pump system through the air outlet 23; another portion of the humid and hot air undergoes primary condensation through the first condensing channel and then is discharged into the heat pump system through the air outlet 23.

[0042] This application also discloses some embodiments, in which the heating assembly further includes a heating structure; the clothing treatment device further includes a heat pump system; the heat pump system includes a first heat exchanger and a second heat exchanger; the first heat exchanger forms the heating structure; and the second heat exchanger forms a second condensation structure.

[0043] The working principle of the clothing processing device in this application is as follows: When the heat pump washer-dryer dries clothes, the fan starts and drives the air inside the drum to circulate. When the hot and humid air circulates back into the drum, it flows in two directions. The first direction is the same as in a traditional heat pump washer-dryer, where the hot and humid air directly reaches the air outlet 23. The other direction is that the hot and humid air enters the condensing ring through the first air guide 21. Since the condensing ring has a circular structure, when the hot and humid air enters the condensing ring, the air flows from the left and right sides. The air velocity flowing into the left or right side is much slower than the air velocity entering from the first air guide 21. Therefore, according to V=s / t, the residence time in the left and right air ducts will be longer, increasing the condensation time of the air ducts and ensuring sufficient heat exchange between the hot and humid air and the air duct wall of the condensing ring, thus maximizing the heat exchange.

[0044] Water vapor condenses out; at the same time, compared with the traditional rear duct condenser, this structure allows the air to flow through a longer duct when the same amount of air comes in from the first air guide 215, which will also fully condense the hot and humid air.

[0045] According to another aspect of this application, a washer-dryer combo is provided, including a clothing handling device, which is the aforementioned clothing handling device.

[0046] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above description is merely a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
