They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0062] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0063] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0064] like Figure 1-8 As shown, the present invention provides a door structure 1, including: a door body 1 and an air duct 2 disposed on the door body 1, with an air duct cover 3 disposed on the air duct 2. The door structure 1 includes:

[0065] A filter element 4 is provided on the duct cover 3, which can be opened and closed relative to the air inlet area 33 of the duct cover 3;

[0066] The air inlet area 33 of the duct cover 3 is connected to the duct 2 via the filter element 4.

[0067] In the embodiments of the present invention, by setting the filter element 4 on the air duct cover 3 and opening and closing relative to the air inlet area 33 of the air duct cover 3, the filter element 4 can be installed on the air duct 2 of the door body 1 together with the air duct cover 3 or removed from the air duct 2 of the door body 1. On the basis of filtering the gas flowing through the air duct 2 to purify the gas in the air duct 2, the filter element 4 can be easily installed, replaced or cleaned.

[0068] The aforementioned door structure 1 is used in a clothes dryer. The clothes dryer includes a drying drum and the door structure 1. The opening of the drying drum faces forward, and the drum shaft extends horizontally. A vibration gap is provided between the bottom of the drying drum and the bottom of the dryer housing to bring the drying drum and the bottom of the dryer housing as close as possible. The air duct 2 is connected to the air outlet 211 of the drying drum. Through the above arrangement, the position of the drying drum in this application is moved downward relative to the position of the drying drum in existing clothes dryers, thereby moving the position of the drying drum opening downward relative to the position of the existing drying drum opening, making it easier for users to put clothes into the drying drum.

[0069] When the air outlet 211 of the clothes dryer is the opening of the clothes dryer, the air duct 2 is connected to the opening of the clothes dryer.

[0070] The air duct 2 of this application can directly discharge the hot and humid gas from the dryer drum outlet to the outside. Alternatively, the air duct 2 of this application is part of the dryer circulation air duct 2, which can discharge the hot and humid gas from the dryer drum outlet to the remaining part of the dryer circulation air duct 2 to turn the hot and humid gas into dry gas and send the dry gas into the dryer drum. The filter element 4 can filter out lint and impurities in the hot and humid gas, so that the hot and humid gas discharged from the air duct 2 is purified hot and humid gas.

[0071] The position of the dryer drum in this application is moved downward, which makes the space above the dryer drum relatively larger inside the dryer. When the air duct 2 in this application is the drying air duct 2, it can provide sufficient space for the setting of the drying air duct 2 for drying the dryer drum and the heat pump module.

[0072] The dryer of this application can be used as a standalone unit. The dryer of this application can be used on the ground or suspended on a support component, such as a wall.

[0073] The dryer of this application can be combined with itself or with other equipment to form a clothing processing device. The clothing processing device is an integrated washing and care device. The clothing processing device includes a first clothing processing module and a second clothing processing module stacked together. The first clothing processing module and / or the second clothing processing module is the dryer of this application. Specifically, the first clothing processing module includes a first housing, and the second clothing processing module includes a second housing. The first housing is stacked on the second housing, or the first housing and the second housing are integrally formed to form a housing. The drying drum of the dryer of this application is located inside the housing. Preferably, the first clothing processing module is the dryer of this application, and the second clothing processing module is a washing machine for washing clothes. In addition, it should be noted that the above-mentioned dryer has at least one drying drum, and the washing machine has at least one washing drum.

[0074] It should be noted that the filter element 4 of this application can be installed on the duct cover 3 located inside the duct 2, or on the duct cover 3 located outside the duct 2.

[0075] In embodiments of the present invention,

[0076] Filter element 4 has a filter chamber 41;

[0077] The opening 411 of the filter chamber 41 faces the air inlet area 33 of the air duct cover 3;

[0078] The filter section 412 of the filter chamber 41 cooperates with the interior of the air duct 2 to define a connecting flow channel 5 that connects the air outlet area 21 of the filter chamber 41 and the air duct 2.

[0079] In an embodiment of the present invention, when the air is vented, the hot and humid air in the drying drum enters the filter chamber 41 through the air inlet area 33 of the air duct cover 3 for filtration. The filtered hot and humid air enters the connecting channel 5 and is then discharged through the air outlet area 21 of the air duct 2. The air inlet area 33 of the air duct cover 3 is formed by a plurality of air inlets 331, and the air outlet 211 of the air duct 2 is formed by a plurality of air outlets 211.

[0080] At least a portion of the filter section 412 can extend into the air duct 2 and cooperate with the interior of the air duct 2 to define a connecting flow channel 5; or, the filter section 412 is provided independently of the air duct 2 and cooperates with the interior of the air duct 2 to define a connecting flow channel 5.

[0081] Specifically, the filter section 412 is located on the front side of the filter chamber 41, and is provided with a gap between it and the inner wall of the opposite air duct 2 to define the connecting flow channel 5; the top of the connecting flow channel 5 coincides with at least part of the air outlet area 21 of the air duct 2.

[0082] For example, at least a portion of the filter section 412 extends into the air duct 2 and is provided with a distance from the opposite air duct 2 to define a connecting flow channel 5, or the filter section 412 is provided independently of the air duct 2 and is provided with a distance from the opposite air duct 2 to define a connecting flow channel 5.

[0083] In another embodiment of the present invention, the front side of the filter cavity 41 is fitted to the inner wall of the opposite air duct 2, and the filter part 412 is disposed at the top of the filter cavity 41 and overlaps with at least part of the air outlet area 21 of the air duct 2.

[0084] When the air is vented, the hot and humid air inside the dryer enters the filter chamber 41 through the air inlet area 33 of the air duct cover 3 for filtration, and the filtered hot and humid air is discharged through the air outlet area 21 of the air duct 2.

[0085] In embodiments of the present invention, the filter element 4 includes:

[0086] Filter element 4 includes:

[0087] The filter housing 42 is ring-shaped;

[0088] The filter screen 43 is flat and serves as the filter section 412. It is located inside the filter screen housing 42 and forms a filter chamber 41 with the inner wall of the filter screen housing 42, which is open at the rear and closed at the front by the filter screen 43.

[0089] The rear opening of the filter chamber 41 is the opening 411, which is fastened to the air inlet area 33 of the air duct cover 3.

[0090] In specific embodiments of the present invention, the outer periphery of the filter screen 43 abuts against the inner periphery of the filter screen housing 42, and the filter screen 43 and the inner wall of the filter screen housing 42 form a filter cavity 41; the filter screen 43 serves as a filter part 412, the rear opening of the filter cavity 41 serves as an opening part 411, and the filter part 412 is located on the front side of the filter cavity 41 relative to the opening part 411.

[0091] The filter housing 42 not only provides a space for the installation of the filter 43, but also ensures that the filter 43 is installed inside the filter housing 42. This design ensures that when the gas passes through the filter housing 42, it will inevitably pass through the filter 43. The main function of the filter 43 is to block and capture impurities in the gas. The filter pores of the filter 43 are designed to be small enough to allow only clean gas molecules to pass through, thereby achieving effective filtration of the gas.

[0092] The air intake area 33 of the air duct cover 3 is formed by a number of air inlets 331. The arrangement of the number of air inlets 331 can speed up and evenly introduce air.

[0093] The filter chamber 41 is fastened to the air inlet area 33 of the duct cover 3. Specifically, the opening 411 of the filter chamber 41 surrounds the air inlet area 33 of the duct cover 3, increasing the air inlet area of ​​the hot and humid gas.

[0094] The filter housing 42 is annular and has a first open end and a second open end. The first open end serves as the opening 411 of the filter 43.

[0095] The filter screen 43 can be installed on the filter screen housing 42 at the first opening end, the second opening end, or between the first opening end and the second opening end. The filter screen 43 can be fixedly installed on the filter screen housing 42 by means of screwing, magnetic attraction or snap-fit. Of course, the filter screen 43 can be integrally formed with the filter screen housing 42.

[0096] The specific assembly of filter screen 43 and filter screen housing 42 is as follows:

[0097] like Figure 2 and Figure 3As shown, in the first method: the filter screen 43 is a square flat plate, and the filter screen housing 42 is a square ring. Specifically, the filter screen housing 42 includes a top wall, a left side wall, a right side wall, and a bottom wall. The bottom wall extends horizontally and is flush with the left side wall and the right side wall respectively. The top wall is arc-shaped and protrudes outward from the filter screen housing 42. The top wall is flush with the left side wall and the right side wall respectively. The left side wall and the right side wall extend vertically.

[0098] When the filter screen 43 is installed at the second opening end, the outer periphery of the filter screen 43 abuts against the inner periphery of the second opening end. The dimensions of the left and right side walls of the filter screen housing 42 gradually increase from top to bottom, so that the second opening end of the filter screen housing 42 gradually extends outward from top to bottom, and the filter screen 43 gradually extends outward from top to bottom, covering the second opening end of the filter screen housing 42.

[0099] like Figure 6 and Figure 7 As shown, in the second method: the filter screen 43 is a square flat plate, and the filter screen housing 42 is a square ring. Specifically, the filter screen housing 42 includes a top wall, a left side wall, a right side wall, and a bottom wall. The bottom wall extends horizontally and is flush with the left side wall and the right side wall respectively. The top wall is arc-shaped and protrudes outward from the filter screen housing 42. The top wall is flush with the left side wall and the right side wall respectively. The left side wall and the right side wall extend vertically.

[0100] When the filter screen 43 is installed at the second opening end, the dimensions of the left and right side walls of the filter screen housing 42 remain unchanged from top to bottom, so that the second opening end of the filter screen housing 42 extends vertically and the filter screen 43 extends vertically.

[0101] like Figure 8 As shown, in the third method: the filter screen 43 is a square flat plate, and the filter screen housing 42 is a square ring. Specifically, the filter screen housing 42 includes a top wall, a left side wall, a right side wall, and a bottom wall. The bottom wall is arc-shaped and protrudes outward from the filter screen housing 42, and is flush with the left side wall and the right side wall respectively. The top wall is arc-shaped and protrudes outward from the filter screen housing 42. The top wall is flush with the left side wall and the right side wall respectively. The left side wall and the right side wall extend vertically.

[0102] When the filter screen 43 is installed on the filter screen housing 42 between the first open end and the second open end, the dimensions of the left and right side walls of the filter screen housing 42 remain unchanged from top to bottom, and the filter screen 43 gradually slopes downward from the top of the first open end to the bottom of the second open end.

[0108] In an embodiment of the present invention, the air inlet 331 penetrates the bottom of the receiving groove 31 in the front-to-back direction, and the receiving groove 31 can increase the sealing performance of the filter chamber 41.

[0109] Furthermore, the filter screen 43 is located in the receiving groove 31 and defines a connecting flow channel 5 with the inner wall of the opposite air duct 2. That is, the filter screen 43 is located entirely in the receiving groove 31 and is set independently from the air duct 2, defining a connecting flow channel 5.

[0110] Alternatively, at least a portion of the filter screen 43 extends into the air duct 2 through the opening of the receiving groove 31, defining a connecting flow channel 5 with the inner wall of the opposite air duct 2.

[0113] When the filter screen 43 and the filter screen housing 42 are assembled in the second manner described above, at least a portion of the upper part of the filter screen housing 42 and at least a portion of the lower part of the filter screen housing 42 are exposed outside the receiving groove 31 through the groove opening of the receiving groove 31 and extend into the air duct 2, or the entire filter screen housing 42 is located inside the receiving groove 31.

[0114] When the filter screen 43 and the filter screen housing 42 are assembled in the third manner described above, at least a portion of the upper part and at least a portion of the lower part of the filter screen housing 42 are exposed outside the receiving groove 31 through the opening of the receiving groove 31 and extend into the air duct 2, or the entire filter screen housing 42 is located inside the receiving groove 31.

[0115] In embodiments of the present invention, the filter element 4 is detachably mounted on the duct cover 3 via a fixing member or rotatably mounted on the duct cover 3 via a rotating member 6.

[0116] In specific embodiments of the present invention, the filter element 4 is detachably installed in the receiving groove 31 via a fixing member to form a filter cavity 41; and / or, the filter screen housing 42 is rotatably installed in the receiving groove 31 via a rotating member 6 to form or release the filter cavity 41.

[0117] The fasteners include 72 snap fasteners or magnetic fasteners. The filter screen housing 42 is snapped into the receiving groove 31 via the 72 snap fasteners, or the filter screen housing 42 is magnetically attracted to the receiving groove 31 via the magnetic fasteners. Specifically, the filter screen housing 42 is snapped into or magnetically attracted to the bottom of the receiving groove 31, so that the filter screen housing 42 can be detachably installed on the air duct cover 3.

[0118] The rotating component 6 includes a first horizontal rotating shaft 1061. The filter screen housing 42 is rotatably mounted on the air duct cover 3 via the first horizontal rotating shaft 1061 and can be flipped up and down on the air duct cover 3. Specifically, the first horizontal rotating shaft 1061 can be installed in the receiving groove 31.

[0119] It should be noted that when the filter screen 43 and the filter screen housing 42 are assembled in the first manner described above, the filter screen housing 42 is detachably mounted on the air duct cover 3 by means of fasteners.
