Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0045] It should be noted that in the description of this utility model, terms such as "horizontal," "vertical," "left," and "right," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0046] Furthermore, it should be noted that in the description of this utility model, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] Specifically, this utility model provides a garment processing device, such as... Figure 1 As shown, the garment processing equipment of this utility model includes a box 1 and a roller 2 installed inside the box 1. The roller 2 is rotatable relative to the box 1.

[0048] Among them, the clothing processing equipment of this utility model can be a drum washing machine. The drum washing machine includes an outer drum and an inner drum that is rotatably disposed in the outer drum. A driving device is provided at the rear end of the outer drum. The driving device is used to drive the inner drum to rotate. The drum 2 is the inner drum.

[0049] The clothing processing equipment of this utility model can also be a dryer, with the drum 2 being a drying drum. The clothing processing equipment of this utility model can also be a washer-dryer combo. Whether it is a dryer or a washer-dryer combo, a drying device is also installed inside the housing 1. The drying device can extract the humid air in the drum 2, dehumidify and heat it, and then send it back to the drum 2. By making the airflow circulate between the drum 2 and the drying device, the clothes in the drum 2 can be dried.

[0050] For example, the drying device includes a heat pump module, a drying fan 32, and a drying duct 31. The two ends of the drying duct 31 are connected to the front end and the rear end of the drum 2, respectively. The evaporator 33 and the condenser 34 of the heat pump module are both installed in the drying duct 31. The evaporator 33 is located upstream of the condenser 34. The evaporator 33 is used to dehumidify the humid air, and the condenser 34 is used to heat the airflow. The drying fan 32 is also installed in the drying duct 31 so that the airflow can circulate between the drum 2 and the drying duct 31.

[0051] It should be noted that those skilled in the art can also use other types of dehumidification components and heating components to replace the evaporator 33 and condenser 34 described above in practical applications. Such flexible adjustments and changes do not deviate from the principles and scope of this utility model and should be limited to the protection scope of this utility model.

[0052] Furthermore, it should be noted that, in practical applications, those skilled in the art can position the air inlet of the drying device closer to the front end of the drum 2 and the air outlet of the drying device closer to the rear end of the drum 2. During the drying process, the humid air inside the drum 2 is discharged from the front end of the drum 2 and enters the drying device. After being dehumidified and heated by the drying device, it re-enters the drum 2 from the rear end. Alternatively, the air inlet of the drying device can be positioned closer to the rear end of the drum 2 and the air outlet of the drying device closer to the front end of the drum 2. During the drying process, the humid air inside the drum 2 is discharged from the rear end of the drum 2 and enters the drying device. After being dehumidified and heated by the drying device, it re-enters the drum 2 from the front end. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be limited to the protection scope of this utility model.

[0053] Preferably, such as Figure 1 As shown, the air inlet of the drying device of this utility model is located below the opening of the drum 2, and the air outlet of the drying device is connected to the rear end of the drum 2.

[0054] Exemplarily, as shown in Figure 1 The drying device is located below the drum 2, and a drying air duct 31 extends from the front end (the left end as viewed from above) of the drum 2 to the rear end (the right end as viewed from above) of the drum 2. Figure 1 When the drying program is executed, the drying fan 32 is started, the wet air in the drum 2 is discharged from the drum opening and enters the drying air duct 31, then flows along the drying air duct 31 towards the rear end of the drum 2, enters the drum 2 from the rear end of the drum 2 after being dehumidified and heated, and dries the clothes in the drum 2. Figure 1 Preferably, as shown in

[0055] The clothes treating apparatus further comprises a lint collecting box 4 installed at the drum opening of the drum 2, and the airflow discharged from the drum opening first flows through the lint collecting box 4 and then enters the drying device. Figure 1 The lint collecting box 4 can filter and collect the lint and other impurities carried by the airflow, and prevent the impurities from entering the drying air duct 31.

[0056] Preferably, as shown in

[0057] The clothes treating apparatus further comprises an air supply device installed in the cabinet 1, and the air supply device is located in front of the drum 2 and can supply air towards the inner bottom of the drum 2. Figure 1 During the execution of the drying program, the air supply device supplies air towards the inner bottom of the drum 2, so that the air directly blows on the clothes located at the bottom of the drum 2, which is beneficial to improve the heat and moisture exchange efficiency between the clothes and the drying airflow, thereby improving the drying efficiency of the clothes treating apparatus, speeding up the drying speed, and reducing the rotation speed of the drum 2. In some cases (for example, when there are fewer clothes), the drum 2 can even not be rotated, which greatly reduces the mechanical wear of the clothes. In addition, since the air supply device is installed in front of the drum 2, it can directly blow air into the drum 2 through the drum opening, and the air force is stronger, so that the air supply device can provide strong air to impact the clothes in the drum 2, which is beneficial to make the clothes more fluffy, and the user wears more comfortable. In addition, strong air is also beneficial to strip the dust, hair and other impurities on the clothes.

[0058] Preferably, as shown in

[0059] After the air blown by the air supply device enters the drum 2, it first flows towards the rear end of the drum 2, turns back and then flows towards the front end of the drum 2, and then enters the air supply device from the drum opening at the front end of the drum 2. Figure 1

[0061] It should be noted that, in the case where the drying device and the lint collecting box 4 are provided, the air flow discharged from the drum port of the drum 2 is preferably first passed through the lint collecting box 4, and then divided into two air flows which respectively enter the drying device and the air supply device. If there is no drying device, only the lint collecting box 4, the air flow filtered by the lint collecting box 4 only flows into the air supply device.

[0062] In addition, it should be noted that not only the clothes dryer and the washer-dryer can be provided with the air supply device and the lint collecting box 4, but also the washing machine can be provided with the air supply device and the lint collecting box 4, and both are installed at the drum port of the drum 2. In this case, the air blown by the air supply device first flows towards the rear end of the drum 2 after entering the drum 2, and then reverses and flows towards the front end of the drum 2. After being discharged from the drum port at the front end of the drum 2, the air first passes through the lint collecting box 4 and then enters the air supply device.

[0063] Through the above arrangement, the washing machine has the dust and hair removal function in addition to the washing function. Specifically, when the user's clothes have dust or a large amount of hair (such as cat hair), but the user does not want to wash the clothes, the clothes can be placed in the inner drum of the washing machine, and then the air supply device is turned on to supply air to the inner drum. When the strong wind blows on the clothes, the dust and hair on the clothes can be removed. When the air flow passes through the lint collecting box 4, the dust and hair are filtered and collected by the lint collecting box 4, so that the dust and hair on the clothes are stripped.

[0064] It should be noted that in addition to the washing machine, the clothes dryer and the washer-dryer can also be used without turning on the drying device, and only the air supply device is turned on to remove the dust and hair on the clothes.

[0102] Exemplarily, a plurality of clamping grooves 711 are provided on the fixed plate 71, and each side of the plate-shaped body 721 of the air door 72 has one rotating shaft 722, each rotating shaft 722 is rotationally connected with a corresponding clamping groove 711, when the air door 72 is opened, the limiting structure rotates with the rotating shaft 722, and when the limiting structure is in abutment with the fixed plate 71, the rotating shaft 722 is prevented from continuing to rotate, thereby limiting the air door 72 at the set open position, and the plurality of plate-shaped bodies 721 are arranged in parallel, and a wind guide channel is formed between adjacent two plate-shaped bodies 721.

[0103] It should be noted that the shape of the plate-shaped body 721 of each air door 72 can be the same or different, and preferably the shape of the plate-shaped body 721 of each air door 72 is set according to the shape of the air outlet of the air blower 5.

[0104] For example, if the shape of the air outlet is square, the plate-shaped body 721 of each damper 72 can be set to the same shape, and if the shape of the air outlet is circular, the plate-shaped body 721 of each damper 72 is preferably set to match the shape of the air outlet at the installation position of the damper 72.

[0105] In addition, it should be noted that the specific structure of the limiting structure is not limited in the present application, for example, the skilled in the art can set the limiting structure as a limiting block, a limiting plate or a limiting column, etc.

[0106] Preferably, as shown in the drawings, the limiting structure is a limiting block 723, and the limiting block 723 has a stop surface 7231, which abuts against the fixed plate 71 when the damper 72 is opened to a set opening position. Figures 6 to 11

[0107] Exemplarily, the limiting block 723 is approximately fan-shaped, and the end surface of the top of the limiting block 723 is the stop surface 7231.

[0108] Preferably, the limiting block 723 is provided with a hollow structure (not shown in the drawings), which is arranged close to the stop surface 7231.

[0109] By arranging the hollow structure close to the stop surface 7231, the weight of the lower part of the limiting block 723 is greater than that of the upper part, which is more conducive to closing the damper 72 by its own gravity.
