[0088] The present application will be further described below in conjunction with the drawings and specific embodiments. The following description is merely illustrative of the basic principles of the present application and is not intended to limit it.

[0089] In order for those skilled in the art to which the present disclosure pertains to have a clearer understanding of the present disclosure, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present disclosure.

[0090] During the process of washing or drying, lint will be generated from the laundry, and the lint will be distributed everywhere in the laundry treatment equipment along with the airflow. Therefore, after the laundry treatment equipment has been operated for a period of time, the lint will gradually accumulate, thereby affecting the cleanliness of the laundry and the laundry treatment equipment itself, and gradually affecting the airflow circulation of the laundry treatment equipment, and then affecting the drying effect of the laundry.

[0091] Based on the above technical problems, the present disclosure provides a cleaning device and a laundry treatment equipment, aiming to improve the technical problems of low cleanliness of the laundry treatment and the laundry treatment equipment itself and poor drying effect.

[0092] The design idea of the present disclosure is to set a filter body in the laundry treatment, filter the lint in the laundry treatment device through the filter body, and optionally set a cleaning member in the filter body, so that the lint in the filter body is discharged out of the filter body through the movement of the cleaning member in the filter body, thereby achieving the technical effects of keeping the interior of the laundry treatment equipment clean and avoiding affecting the airflow circulation in the interior of the laundry treatment equipment.

[0093] The specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. Identical or similar reference numerals can be used to designate identical or similar parts throughout the various drawings. The use of identical or similar reference numerals in different drawings does not mean that all drawings described by the identical or similar reference numerals constitute a single or same embodiment.

In another embodiment, the filter body 521 includes at least one filter sheet integrally formed or clamped to the support body 522 to combine at least one grid.

[0113] According to another embodiment of the present disclosure, the filter holes can also be directly provided on the first filter 52, so that the first filter 52 with the filter holes directly serves as the air outlet portion 52b and the filter body 521. That is, the first filter 52 can be rigid, and can have a plurality of filter holes on the bottom and / or the sidewall of the first filter 52 to filter the lint in the air flow, without the need for additional configuration of the filter body 521 and the support body 522. The first filter 52 can be configured to have smooth inner walls, and is preferably made of a material that is not easily corroded, such as metal or PVC.

[0114] It should be noted that in the embodiment shown in FIG. 4, since the clothing blocking member 51 is combined with the first filter 52 through the connecting member 52c, and the opening between the ribs of the clothing blocking member 51 has the effect of air inlet, the opening of the clothing blocking member 51 can also be considered as the upper opening of the first filter 52, that is, the air inlet portion 52a of the first filter 52. In an embodiment, the clothing blocking member 51 can not be connected to the first filter 52 through the connecting member 52c, but can be connected to the first filter 52 in a separable manner such as clamping or bonding. In another embodiment, the clothing blocking member 51 can be directly configured on the first filter 52 in a non-separable manner, for example, in an integral molding manner. In another embodiment, the clothing blocking member 51 can always be separated from the first filter 52. At this time, even though the opening between the ribs of the clothing blocking member 51 has the effect of air inlet, since the clothing blocking member 51 is not combined with the first filter 52, the opening of the clothing blocking member 51 is no longer considered as the air inlet portion 52a of the first filter 52, but the actual air inlet portion (for example, the upper opening) of the first filter 52 is considered as the air inlet portion 52a of the first filter 52.

[0115] In other words, in the embodiment shown in FIG. 4, because the blocking member 51 is combined with the first filter member 52 through the connecting member 52c, and the opening between the ribs of the blocking member 51 has the effect of air inlet, the opening of the blocking member 51 can be in communication with the upper opening (air inlet 52a) of the first filter member 52, and the airflow can enter the filter cavity 53 through the opening of the blocking member 51 and the air inlet 52a (the upper opening of the first filter member 52). In an embodiment, the blocking member 51 can not be connected with the first filter member 52 through the connecting member 52c, but can be directly connected with the first filter member 52 in a separable manner such as clamping, bonding, etc. In another embodiment, the blocking member 51 can also be directly connected with the first filter member 52 in a non-separable manner, for example, the blocking member 51 can be arranged on the first filter member 52 in an integral manner. In another embodiment, the blocking member 51 can always be separated from the first filter member 52, and at this time, the opening of the blocking member 51 is arranged in a spaced manner with the upper opening (air inlet 52a) of the first filter member 52. Even though the opening between the ribs of the blocking member 51 has the effect of air inlet, because the blocking member 51 is not combined with the first filter member 52, the airflow entering the filter cavity 53 can not pass through the opening of the blocking member 51, but can pass through the gap between the blocking member 51 and the first filter member 52, the upper opening (air inlet 52a) of the first filter member 52 to enter the filter cavity 53, or the airflow can directly pass through the upper opening (air inlet 52a) of the first filter member 52 to enter the filter cavity 53.

[0116] In addition, FIG. 4 is used to explain to the reader how the airflow flows through the first filter member 52, and does not limit whether the airflow direction is from top to bottom. It can be understood that the cleaning device 5 can also be installed at other positions of the laundry treatment apparatus, and therefore, the airflow can also flow front to back, left to right, or obliquely relative to the laundry treatment apparatus, which is not limited by the present disclosure.

[0117] FIGS. 3 and 4 show a simple cleaning device 5a which at least has a first filter member 52, can achieve filtering of most of the lint in the airflow, and enables the user to at least separate at least one of the first filter member 52 and the lint collecting member 57 (if any) from the laundry treatment apparatus to achieve cleaning of the first filter member 52 or the lint collecting member 57 (if any). However, the cleaning device 5a still needs to be improved in terms of the convenience of removing the filtered lint. The cleaning device 5 according to other embodiments of the present disclosure will be described below with reference to FIGS. 5-18.

[0118] Figure 5 is a sectional view of a cleaning device 5b according to another embodiment of the present disclosure, and Figure 6 is an exploded view of the cleaning device 5b of Figure 5. The cleaning device 5b is one of the cleaning devices 5. As shown in Figures 5 and 6, similar to the cleaning device 5a, the cleaning device 5b also includes the clothing 51, the first filter 52, and the dust collecting member 57, and the structures and functions of these components in the cleaning device 5b are substantially the same as those in the cleaning device 5a unless otherwise specified. Therefore, the corresponding descriptions of Figures 3-4 can be referred to and will not be repeated here.

[0119] As shown in Figures 5 and 6, different from the cleaning device 5a shown in Figures 3 and 4, the cleaning device 5b further includes a cleaning member 510a, a first driving member 517, a support member 518, and a bearing 519. The first driving member 517 has a rotating output. One end of the cleaning member 510a is connected to the output of the first driving member 517 to rotate in the first filter 52 (filter cavity 53) under the driving of the first driving member 517, and scrape and transfer the hair dust from the inside of the first filter 52 to the dust collecting member 57. The other end of the cleaning member 510a is arranged in the inner ring of the bearing 519, and the rolling of the inner and outer rings of the bearing 519 achieves the purpose of improving the rotation efficiency of the cleaning member 510a.

[0120] In some embodiments, the first driving member 517 can be a motor, and the output of the motor can be transmitted to the cleaning member 510a through gears, clamping, or the like. According to an embodiment of the present disclosure, the first driving member 517 is arranged outside the filter cavity 53 of the first filter 52, and the output end of the first driving member 517 is clamped to a coupling 517a to connect the cleaning member 510a inside the first filter 52 through the coupling 517a, thereby driving the cleaning member 510a to rotate in the first filter 52 (filter cavity 53). According to another embodiment of the present disclosure, the first driving member 517 can also be arranged inside the first filter 52 (filter cavity 53), and the present disclosure does not limit this.

[0121] In addition, since the hair dust is collected in the first filter 52 (filter cavity 53) through the filter body 521, in order to improve the cleaning effect of the hair dust, the cleaning member 510a can be in contact with the filter body 521, so that the cleaning member 510a can effectively scrape the hair dust (the hair dust adheres to the filter body 521) collected by the filter body 521. The bottom of the filter cavity 53 formed by the first filter 52 can be arc-shaped, for example, the cavity of the filter cavity 53 can be semicircular or large semicircular, so that the first filter 52 is coaxial with the cleaning member 510a. In another embodiment, the first filter 52 is a rigid member with an arc-shaped bottom and filter holes, and the cleaning member 510a can be in contact with the bottom of the first filter 52 to collect the hair dust.

[0122] The first filter 52 is coaxially arranged with the cleaning member 510a, so that the part of the cleaning member 510a located in the filter cavity 53 can always be in contact with the cavity wall of the filter cavity 53 during rotation, thereby improving the cleaning effect of the cleaning member 510a on the first filter 52.

[0123] In an embodiment, the cleaning member 510a is in contact with other parts of the first filter 52 in addition to the filter body 521, for example, the first filter 52 is in contact with the support body 522, so as to avoid the hair dust remaining on the support body 522. In another embodiment, the cleaning member 510a is not in contact with other parts in the filter cavity 53 in addition to the filter body 521 and the ribs of the support body 522 around the filter body 521, so as to reduce friction and improve the service life of the cleaning member 510a.

[0124] Compared with the aforementioned cleaning device 5a, the cleaning device 5b can filter and collect hair dust more quickly and efficiently, reduce the cleaning difficulty of the clothes and the processing equipment thereof, and ensure the circulation of the air flow. The cleaning device 5b can automatically maintain the cleaning solution by rotating the cleaning member 510a to transfer the hair dust filtered and collected by the first filter 52 to the dust collecting member 57. The operation time of the cleaning device 5b can be after the centrifugal dehydration program runs for a specific period of time (for example, after the operation of the clothes dryer ends, or before the operation of the clothes dryer starts), and / or a separate cleaning instruction can be set, which can be started by the user according to the needs, and the present disclosure does not limit this. The detailed arrangement of the first filter 52 and the support body 518 will be described in detail below by referring to FIG. 7.

[0125] Figure 7 is a schematic view of the first filter 52 of the cleaning device 5b shown in Figure 5. As shown in Figure 7, the side of the first filter 52 away from the first driving member 517 includes a recess (also referred to as a communication portion) 55, which can be used to lap the receiving portion 571 of the dust collecting member 57, so that the cleaning member 510a can smoothly enter the dust collecting member 57 when transferring the lint in the first filter 52 (filtering cavity 53) to the dust collecting member 57, and not leak due to the vertical downward gap between the dust collecting member 57 and the first filter 52. According to another embodiment of the present disclosure, the side of the first filter 52 away from the first driving member 517 can also not include the above-mentioned recess (also referred to as a communication portion) 55, and the receiving portion 571 of the dust collecting member 57 can be directly abutted by the first filter 52. According to another embodiment of the present disclosure, the side of the first filter 52 away from the first driving member 517 can also not include the above-mentioned recess (also referred to as a communication portion) 55, and the dust collecting member 57 can also not include the receiving portion 571, and the first filter 52 and the dust collecting member 57 can be directly abutted and communicated with each other. According to another embodiment of the present disclosure, the side of the first filter 52 away from the first driving member 517 can also protrude into the dust collecting member 57, and the protruding portion can be used as the communication portion 55. The above-mentioned details of the first filter 52 can also be applied to the cleaning device 5a shown in Figures 3 and 4.

[0126] As shown in Figure 7, the support member 518 is arranged at the end of the first filter 52 away from the first driving member 517, so that the bearing 519 rotatably fixes the cleaning member 510a at the end of the first filter 52 away from the first driving member 517, as shown in Figure 5.

[0127] In some embodiments, the bearing 519 can be mounted on the support member 518.

[0128] The support member 518 further includes a cantilever 518a, the root of the cantilever 518a is fixedly arranged inside the first filter 52 (the inner wall of the filtering cavity 53), and the end of the cantilever 518a is provided with an opening for embedding the bearing 519.

[0129] For the purpose of description, the end of the cantilever 518a is defined as a mounting portion 518b, and the opening is defined as a mounting hole 518c, that is, the support member 518 includes the cantilever 518a and the mounting portion 518b, one end of the cantilever 518a is fixedly arranged inside the first filter 52 (the inner wall of the filtering cavity 53), the mounting portion 518b is arranged at the end of the cantilever 518a away from the first filter 52, the mounting portion 518b is provided with the mounting hole 518c, and the bearing 519 is embedded in the mounting hole 518c. In addition to the connection between one end of the cantilever 518a and the first filter 52, the remaining part is arranged in a spaced manner with the inside of the first filter 52 (the inner wall of the filtering cavity 53), that is, the remaining part of the cantilever is arranged in a cantilevered manner.

[0130]

[0131] In order to have sufficient support strength of the cantilever 518a, the cantilever 518a can be integrally formed inside the first filter 52. However, when the laundry treating apparatus is operated, the applicant found that if the cantilever 518a is vertically disposed at an upper position of the inner wall or the bottom of the filter cavity 53 formed by the first filter 52, some lint can be caught on the cantilever 518a or accumulated at the root of the cantilever 518a, and can be out of the rotation range of the helical blade 512 shown in FIG. 6, so that the lint cannot be transferred to the lint collector 57 by the helical blade 512. Therefore, as shown in FIG. 7, the root of the cantilever 518a is fixed inside the first filter (filter cavity 53), and the end of the cantilever 518a is extended to the axis 531 of the filter cavity 53 and connected to the cleaning member 510a through a bearing.

[0132] In some embodiments, the cantilever 518a is in a strip shape, and in order to have sufficient support strength of the cantilever 518a, the cantilever 518a can be integrally formed inside the first filter 52. However, when the laundry treating apparatus is operated, the applicant found that if the cantilever 518a is vertically disposed at an upper position of the inner wall or the bottom of the filter cavity 53 formed by the first filter 52, some lint can be caught on the cantilever 518a or accumulated at the root of the cantilever 518a, and can be out of the rotation range of the helical blade 512 shown in FIG. 6, so that the lint cannot be transferred to the lint collector 57 by the helical blade 512. Therefore, as shown in FIG. 7, the root of the cantilever 518a is fixed inside the first filter (filter cavity 53), and the end of the cantilever 518a is extended to the axis 531 of the filter cavity 53 and connected to the cleaning member 510a through a bearing.

[0133] In some embodiments, the helical blade 512 is disposed on the outer edge of the cleaning member 510a, which is away from the first driving member 517, and can extend to the cantilever 518a, i.e., the cleaning range of the helical blade 512 can cover the cantilever 518a, so that the helical blade 512 can scrape the lint caught on the cantilever 518a or accumulated at the connection between the cantilever 518a and the first filter 52, to some extent, solving the problem of the lint being caught on the cantilever 518a or accumulated at the connection between the cantilever 518a and the first filter 52.

[0134] The cleaning range of the helical blade 512 covering the cantilever 518a means that the helical blade 512 can extend to the cantilever 518a and contact the cantilever 518a during rotation, and scrape the lint caught on the cantilever 518a or accumulated at the connection between the cantilever 518a and the first filter 52.

[0135] In one embodiment, the support 518 is configured to be arranged obliquely to the direction of airflow traveling in the first filter 52, and the cantilever 518a is arranged at a right angle to the vertical diameter of the filter cavity 53, i.e. the cantilever 518a is arranged along the horizontal diameter of the filter cavity 53 on the side wall of the filter cavity 53, and the cantilever 518a and the mounting portion 518b (the entire support 518) are spaced apart from the bottom wall and the other side wall (the side wall opposite to the side wall connecting the cantilever 518a) of the filter cavity 53 and the upper blocking member 51. The spiral blade 512 can contact the cantilever 518a and the hair dust attached to the cantilever 518a during rotation, so that the spiral blade 512 can scrape the hair dust attached to the cantilever 518a. Since the cantilever 518a and the mounting portion 518b (the entire support 518) are spaced apart from the bottom wall and the other side wall of the filter cavity 53 and the upper blocking member 51, the hair dust can enter the dust collecting member 57 through the space between the support 518 and the filter cavity 53 and the space between the support 518 and the blocking member 51, so that the hair dust has sufficient space to enter the dust collecting member 57, ensuring the efficiency of the hair dust being transferred to the dust collecting member 57.

[0136] That is, the hair dust can enter the dust collecting member 57 through the space below the support 518 (the distance between the support 518 and the bottom of the filter cavity 53), the space above the support 518 (the distance between the support 518 and the blocking member 51), and the space on the side of the support (the distance between the support 518 and the other side wall of the filter cavity 53), so that the hair dust has sufficient space to enter the dust collecting member 57, ensuring the efficiency of the hair dust being transferred to the dust collecting member 57.

[0137] As shown in FIG. 7, the cleaning member 510a can be rotatably connected to the end (the mounting portion 518b) of the support 518 by the support 518 having one cantilever 518a. According to another embodiment of the present disclosure, however, the support 518 can have two or more cantilevers 518a, for example, the support 518 is configured such that the two ends of the support 518 are connected to the side walls of the filter cavity 53 face to face, and the cleaning member 510a is rotatably connected in the middle of the support 518, in which case the support 518 can be regarded as having two cantilevers 518a.

[0138] The cleaning member 510a of the cleaning device 5b will be further described below with reference to FIG. 8.

[0139] Figure 8 is a schematic view of the cleaning member 510a of the cleaning device 5b of Figure 5. As shown in Figure 8, the cleaning member 510a comprises a drive shaft 511 and a helical blade 512. The drive shaft 511 is connected to the output of the first driving member 517 via a coupling 517a shown in Figure 6, so as to drive the helical blade 512 disposed on the drive shaft 511 to rotate under the driving of the first driving member 517. The rotating helical blade 512 can transport the dust in the filtering cavity 53 to the dust collecting member 57. In an embodiment, the coupling 517a is coupled to a coaxial sleeve (not shown) via which the drive shaft 511 is driven, wherein the coaxial sleeve is coaxial with the drive shaft 511.

[0140] In an embodiment, the helical blade 512 can be made of a wear-resistant material, so as to compensate for the wear of the helical blade 512 caused by the scraping of the filtering body 521 and the support member 518, and prolong the service life of the helical blade 512. The end portion (side edge) of the helical blade 512 away from the driving member 517 extends from the inner edge (the coupling position of the drive shaft 511 and the helical blade 512) of the helical blade 512 to the outer edge of the helical blade 512, so as to be in elastic contact with the support member 518.

[0141] In an embodiment, the helical blade 512 is made of an elastic material, that is, the helical blade 512 as a whole has elasticity. The side edge of the helical blade 512 away from the driving member 517 extends from the inner edge (the coupling position of the drive shaft 511 and the helical blade 512) of the helical blade 512 to the outer edge (the contact position of the helical blade 512 and the first filtering member 52) of the helical blade 512, so as to be in elastic contact with the support member 518. In other embodiments, the outer edge and the side edge of the helical blade 512 in contact with the first filtering member 52 and the support member 518, respectively, are supported by an elastic material. The elastic material can be formed on the helical blade 512 by injection molding, so as to achieve the effect of making the helical blade 512 in elastic contact with the first filtering member 52 and the support member 518.

[0142] The inner edge 5122 of the helical blade 512 is mounted on the driving shaft 511, and the outer edge 5124 is the free end of the helical blade 512. The helical blade 512 has a first side 5126 opposite to a second side 5128, the first side 5126 is close to the driving member 517, i.e. the first side 5126 is the side edge of the helical blade 512 close to the driving member 517, and the second side 5128 is close to the support member 518, i.e. the second side 5128 is the side edge of the helical blade 512 away from the driving member 517, and the second side 5128 contacts the support member 518 during rotation to scrape the fluff attached to the support member 518. It is easy to understand that the first side 5126 and the second side 5128 are the two ends of the helical blade 512 along the axial direction of the driving shaft 511, and the inner edge 5122 and the outer edge 5124 are the two sides of the helical blade 512 along the radial direction of the driving shaft 511 at the same position, i.e. the first side 5126 and the second side 5128 have the inner edge 5122 and the outer edge 5124 respectively.

[0143] During rotation of the helical blade 521, the outer edge 5124 of the helical blade 512 can contact the cavity wall of the filtering cavity 53, the second side 5128 of the helical blade 512 (which can be the outer edge 5124 of the second side 5128, or the part between the outer edge 5124 and the inner edge 5122 of the second side 5128) contacts the support member 518, and the outer edge 5124 of the helical blade 512, the inner edge 5122 of the helical blade 512 and the part between the outer edge 5124 and the inner edge 5122 of the helical blade 512 contacts the fluff. In any case, since the helical blade 512 has a certain elasticity, a certain amount of deformation can be generated when the helical blade 512 contacts the fluff or the support member 518, which can reduce damage to the helical blade 512 as much as possible during conveying of the fluff, and improve the service life of the helical blade 512.

[0144] As shown in FIG. 8, in an embodiment, the end (side edge) of the helical blade 512 away from the driving member 517 extends from the inner edge of the helical blade 512 (the position where the driving shaft 511 is coupled with the helical blade 512) to the outer edge of the helical blade 512, which is an elastic flange 513 that contacts the support member 518. The outer edge of the helical blade 512 elastically contacts the first filtering member 52. The elastic flange 513 can increase the strength of the helical blade 512, and also increase the contact area of the helical blade 512 with the support member 518, and improve the cleaning effect on the fluff on the support member 518.

[0145] As can be seen from the above, the flange 513 is arranged on the second side 5128 of the spiral blade 512, and the flange 513 can protrude from the second side 5128 of the spiral blade 512 towards the support 518. The flange 513 can have a certain elasticity, and the second side 5128 of the spiral blade 512 can be in contact with the support 518 through the flange 513. Since the flange 513 is arranged to protrude from the second side 5128 of the spiral blade 512, the flange 513 is closer to the support 518, and when the flange 513 is in contact with the support 518, the pressure of the spiral blade 512 on the support 518 is greater, and the friction between the flange 513 and the support 518 is greater, which can scrape more hair attached to the support 518, and improve the cleaning effect of the hair.

[0146] Through the contact between the flange 513 and the support 518, the contact area between the spiral blade 512 and the support 518 can be increased, and the friction between the flange 513 and the support 518 can be increased, which can improve the cleaning effect of the hair on the support 518.

[0147] In addition, the flange 513 can also increase the strength of the spiral blade 512.

[0148] As shown in FIG. 8, the flange 513 is arranged on the end of the spiral blade 512 (the second side 5128) away from the driving member 517, so that the side edge of the spiral blade 512 is in elastic contact with the support 518. According to another embodiment of the present disclosure, the flange 513 can also be arranged on the end of the spiral blade 512 in contact with the support 518, and not arranged on other parts of the spiral blade 512. In another embodiment, the end of the spiral blade 512 (the side edge, also the second side 5128) is not arranged with a protrusion, that is, does not include the flange 513, and is directly in contact with the support 518.

[0149] As shown in FIG. 8, in an embodiment, the cleaning member 510a further comprises a reinforcing portion 514. The reinforcing portion 514 is arranged at the outer edge of the helical blade 512 away from the driving shaft 511, so as to increase the strength of the helical blade 512 and increase the contact area between the helical blade 512 and the first filter member 52, thereby improving the cleaning effect on the first filter member 52. Specifically, the reinforcing portion 514 is arranged at the outer edge of the helical blade 512, and the outer edge of the helical blade 512 is thickened. For example, the reinforcing portion 514 is arranged to extend to both sides of the outer edge of the helical blade 512, so that the reinforcing portion 514 protrudes from both sides of the helical blade 512; or the reinforcing portion 514 is arranged to extend to one side of the outer edge of the helical blade 512, so that the reinforcing portion 514 protrudes from one side of the outer edge of the helical blade 512 but not from both sides; or the reinforcing portion 514 is arranged to extend to one or both sides of the helical blade 512 from the inner edge to the outer edge, but the reinforcing portion 514 does not protrude from the one or both sides of the helical blade 512 from the inner edge to the outer edge. In another embodiment, the cleaning member 510a can also be without the reinforcing portion 514, i.e., the edge thickness of the helical blade 512 is the same as or smaller than the thickness of other parts.

[0150] In some embodiments, along the radial direction of the driving shaft 511, the helical blade 512 has an inner edge 5122 and an outer edge 5124, the outer edge 5124 is connected with the reinforcing portion 514, and the inner edge 5122 is connected with the outer surface of the driving shaft 511. In the case where the cleaning member comprises the reinforcing portion 514, the side of the helical blade 512 away from the reinforcing portion 514 is the above-mentioned outer edge 5124, and the connection between the helical blade 512 and the outer surface of the driving shaft 511 is the above-mentioned inner edge 5122.

[0151] In addition, according to an embodiment of the present disclosure, the helical blade 512 has a first end portion 51291 and a second end portion 51292 in the radial direction of the driving shaft 511, the first end portion 51291 is connected with the reinforcing portion 514, and the second end portion 51292 is connected with the driving shaft 511, the thickness of the first end portion 51291 is less than the thickness of the second end portion 51292. In the process of cleaning the lint, the outer edge 5124 is in contact with the cavity wall of the filtering cavity 53, and if there is a large amount of lint, the outer edge 5128 (the reinforcing portion 514) may be in abutment with the filtering cavity 53 or the lint, so that the helical blade 512 is deformed. In the direction close to the reinforcing portion 514, the thickness of the first end portion 51291 is less than the thickness of the second end portion 51292, so that the first end portion 51291 of the helical blade 512 is more easily deformed. In this way, the side close to the lint of the helical blade 512 can be deformed to buffer the force when the reinforcing portion 514 is in contact with the lint, so as to avoid the rigid contact between the reinforcing portion 514 and the lint or the cavity wall of the filtering cavity 513. Since the thickness of the first end portion 51291 is less than the thickness of the second end portion 51292, the helical blade 512 is less likely to be deformed as it is closer to the driving shaft 511. In this way, the helical blade 512 can provide a certain supporting force when the reinforcing portion 514 is in contact with the lint or the cavity wall of the filtering cavity 513, so that the reinforcing portion 514 can have a certain pressure when it is in contact with the lint, thereby increasing the friction between the reinforcing portion 514 and the lint, making it easier for the reinforcing portion 514 to clean the lint attached to the cavity wall of the filtering cavity 513, so that the lint can enter the lint collecting member 57 along the rotation direction of the entire helical blade 512, thereby improving the cleaning effect of the lint.

[0152] In some embodiments, the thickness of the entire helical blade 512 decreases in the direction from the driving shaft 511 to the reinforcing portion 514, that is, the first end portion 51291 is the area with the smallest thickness on the entire helical blade 512. In this way, the helical blade 512 can be uniformly deformed and can provide uniform supporting force. In other embodiments, the thickness of the middle region of the blade 5129 can be the smallest, and the middle region connects the first end portion 51291 and the second end portion 51292, which can not be limited in particular.

[0153] Since the first end portion 51291 of the helical blade 512 has a small thickness, which is the smallest area of the helical blade 512 in some embodiments, if the first end portion 51291 directly contacts the lint, the contact area of the helical blade 512 with the lint is small. The thickness of the reinforcing portion 514 along the axial direction of the driving shaft 511 is greater than the thickness of the first end portion 51291 along the axial direction of the driving shaft 511, so that the surface area of the outer edge 5124 (the side of the reinforcing portion 514 away from the first end portion 51291 is the outer edge 5124) can be relatively large. The outer edge 5124 of the helical blade 512 is thickened, the contact area of the helical blade 512 (the outer edge 5124) with the cavity wall of the filtering cavity 513 or the lint is increased, and thus the cleaning effect of the first filter element 52 is improved.

[0154] In addition, the reinforcing portion 514 is located at the end of the entire helical blade 512, which can also play a reinforcing role to enhance the strength of the entire helical blade 512. In addition, according to an embodiment of the present application, as shown in FIG. 8, a weak portion 515 can be provided on the helical blade 512. When the helical blade 512 contacts the first filter element 52, the weak portion 515 on the helical blade 512 deforms, so that the helical blade 512 has elasticity and elastically contacts the first filter element 52. Further elastically contacting the first filter element 52, the helical blade 512 can fully abut against the first filter element 52, effectively cleaning the lint on the first filter element 52, and improving the lint cleaning effect.

[0155] According to an embodiment of the present application, at least part of the helical blade 512 can have a thickness smaller than the thickness of the remaining part to form the above-mentioned weak portion 515. For example, the thickness of the helical blade 512 can be gradually reduced in the direction away from the driving shaft 511 to form the above-mentioned weak portion 515 at the outer edge of the helical blade 512; or the thickness of the middle portion of the helical blade 512 is smaller than the thickness of other parts to form the above-mentioned weak portion 515 at the middle of the helical blade 512.

[0156] According to another embodiment of the present application, the helical blade 512 is made of an elastic material, and the entire helical blade 512 has elasticity, so that the entire helical blade 512 elastically contacts the first filter element 52. According to another embodiment of the present application, the part of the helical blade 512 contacting the first filter element 52 is supported by an elastic material, and the supporting part of the elastic material is integrally formed on the non-elastic helical blade 512, which can also enable the helical blade 512 to elastically contact the first filter element 52, and the present application does not limit this. According to another embodiment of the present application, the part of the helical blade 512 contacting the first filter element 52 is made of an elastic material, and the contacting part of the elastic material is integrally formed on the non-elastic helical blade 512, which can also enable the helical blade 512 to elastically contact the first filter element 52, and the present application does not limit this.

[0157] In one embodiment, the driving shaft 511 has a helical coupling portion protruding from or embedded in the driving shaft 511 to correspond to the inner edge 5122 of the helical blade 512. In one embodiment, the helical coupling portion is assembled with or integrally formed with the driving shaft 511. In another embodiment, the driving shaft 511 does not include the coupling portion and is directly assembled with or integrally formed with the helical blade 512.

[0158] Another embodiment of the cleaning device 5b is described below with reference to FIG. 9.

[0159] FIG. 9 is a schematic view of an embodiment of the present disclosure showing that the end of the support 518 and the driving shaft 511 extends into the dust collecting member 57. As shown in FIG. 9, the end (mounting portion 518b) of the support 518 extends into the dust collecting member 57, and the helical blade 512 is arranged to scrape the cantilever 518a and directly rotate to deliver the dust into the dust collecting member 57, further avoiding the dust blockage or leakage caused by the support 518 arranged in the filter cavity 53. Specifically, the root of the support 518 is connected to the sidewall of the first filter 52, and the end of the support 518 is obliquely connected to the driving shaft 511 extending into the dust collecting member 57, i.e., the included angle between the support 518 and the axis 531 of the filter cavity 53 is an acute angle, so that the end of the support 518 used to connect the driving shaft 511 is directly located in the dust collecting member 57, and the helical blade 512 can directly deliver the dust into the dust collecting member 57. In this embodiment, the dust collecting member 57 is no longer disassembled along the vertical direction, but is disassembled along the horizontal direction or the direction having an oblique angle with the vertical direction.

[0160] As shown in FIG. 9, it is known from the above that the mounting portion 518b extends into the dust collecting member 57, so that part of the driving shaft 511 extends into the dust collecting member 57, and part of the helical blade 512 also extends into the dust collecting member 57 due to the helical blade 512 arranged around the outer circumferential surface of the driving shaft 511. Since the helical blade 512 has the part arranged in the dust collecting member 57, the dust scraped by the helical blade 512 on the cantilever 518a can directly enter the dust collecting member 57, further avoiding the dust blockage or leakage caused by the support 518 arranged in the filter cavity 53. As for the mounting mode of the support 518, the end of the cantilever 518a away from the mounting portion 518b is connected to the sidewall of the filter cavity 53, and the cantilever 518a is obliquely arranged toward the dust collecting member 57, so that the mounting portion 518b extends into the dust collecting member 57, i.e., the included angle between the cantilever 518a and the axis 531 of the filter cavity 53 is an acute angle, so that the mounting portion 518b is directly located in the dust collecting member 57, and the helical blade 512 can directly deliver the dust into the dust collecting member 57.

[0161] In addition, the present disclosure also provides other embodiments that can remove the lint inside the first filter 52 by the movement of the cleaning member to solve the technical problems of lint blockage and difficult cleaning. The mounting manner and detailed structure of the cleaning member reciprocating in the filter cavity 53 will be described in detail below in combination with FIGS. 10-13.

[0162] FIGS. 10-11 respectively show the exploded views of different embodiments of the cleaning device 5c in which the cleaning member 510 can reciprocate. As shown in FIGS. 10-11, the cleaning device 5c includes the clothing blocking member 51, the cleaning member 510b or 510c, the first filter 52, and the lint collecting member 57. Similar to the cleaning device 5a, the cleaning device 5c also includes the clothing blocking member 51, the first filter 52, the filter cavity 53, and the lint collecting member 57 (not shown in the figure), and the structure and function of these components in the cleaning device 5c are generally the same as those in the cleaning device 5a unless otherwise specified, so reference can be made to the corresponding descriptions in FIGS. 3-4, which will not be described again here. The difference between the cleaning device 5c and the cleaning device 5b is that the structure and movement manner of the cleaning member 510b are different, and the cleaning member 510b of the cleaning device 5c moves in the filter cavity 53 to push the lint in the filter cavity 53 into the lint collecting member 57, which is as follows.

[0163] As shown in FIGS. 10 and 11, in order to achieve the reciprocating movement of the cleaning member 510b in the first filter 52 (filter cavity 53), in an embodiment, the cleaning device 5c includes a second driving member 520 that pushes the cleaning member 510b to reciprocate in the filter cavity 53. The cleaning member 510b can be connected to the output end of the second driving member 520, and by the driving of the second driving member 520, the cleaning member 510b can reciprocate in the first filter 52 (filter cavity 53) to push the lint out of the first filter 52 (filter cavity 53) to the lint collecting member 57. The specific structures of the second driving member 520 in FIGS. 10 and 11 are different, as shown in FIG. 10, the second driving member 520 of the cleaning device 5c' is a pneumatic cylinder, and as shown in FIG. 11, the second driving member 520 of the cleaning device 5c” can be a ball screw structure or other mechanical structure having an output end that can reciprocate. The specific structures of the above two second driving members 520 can both drive the cleaning member 510b to reciprocate in the filter cavity 53 in an automatic control manner.

[0164] The second driving member 520 pushes the cleaning member 510b to reciprocate in the filter cavity 53. This means reciprocating movement in the axial direction of the filter cavity 53, which can be reciprocating movement of the cleaning member 510b between the lint collecting member 57 and the second driving member 520. The reciprocating movement mentioned below means reciprocating movement of the cleaning member 510b in the filter cavity 53 between the lint collecting member 57 and the second driving member 520.

[0165] As shown in FIG. 11, in the cleaning device 5c", the circumferential side of the cleaning piece 510b can be provided with a guide piece 516', which can guide the reciprocating movement of the cleaning piece 510b.

[0166] The assembly mode of the guide piece 516' can be to provide a guide groove on the first filter piece 52 or the blocking piece 51, the guide groove extending along the axial direction of the filter cavity 53, and the guide piece 516' can be assembled in the guide groove, so that under the cooperation of the guide piece 516' and the guide groove, the cleaning piece 510b can reciprocate in the axial direction of the filter cavity 53, that is, the reciprocating movement of the cleaning piece 510b between the second driving piece 520 and the chip collecting piece 57 can be realized.

[0167] The cleaning piece 510b has an edge that can move along the bottom and side edge of the first filter piece 52 (filter cavity 53), which can be semicircular, arc-shaped, semicircular, etc., which is not limited in the present disclosure. In another embodiment, the filter cavity 53 formed by the first filter piece 52 of the cleaning device 5c can be a part of other cylindrical shapes, such as a part of a square column, a triangular column, etc., at this time the first filter piece 52 corresponds to an assembly that can form the column cavity, and the cleaning piece 510b is adaptively provided with a shape that can move along the bottom and side edge of the first filter piece 52 (filter cavity 53), such as a square or a triangle, etc.

[0168] FIG. 12 shows another embodiment of the cleaning piece of the present disclosure, as shown in FIG. 12, the cleaning piece 510c of the cleaning device 5c"' can also drive the cleaning piece 510c to reciprocate in the first filter piece 52 (filter cavity 53) by manual pushing and pulling, and push the hair dust from the first filter piece 52 (filter cavity 53) to the chip collecting piece 57 for collection and cleaning. The installation mode and structure of the manually pushed and pulled cleaning piece 510c will be described in detail below in combination with FIGS. 12-13.

[0169] The shape of the cleaning piece 510c shown in FIG. 12 is adapted to the shape of the first filter piece 52, which can be semicircular, arc-shaped, semicircular, etc. In another embodiment, the filter cavity 53 of the cleaning device 5c can be a part of a square column, a triangular column, etc., at this time the first filter piece 52 corresponds to an assembly that can form the part of the square column or the triangular column, and the cleaning piece 510c corresponds to a shape that can move along the bottom and side wall of the filter cavity 53, such as a square or a triangle, etc.

[0170] FIG. 13 is a structural schematic diagram of the cleaning piece 510c of the cleaning device 5c shown in FIG. 12. As shown in FIGS. 12 and 13, the cleaning piece 510c includes an operating part 516, which is manually pushed and pulled to reciprocate the cleaning piece 510c in the filter cavity 53.

[0171] As described above, the cleaning member 510c and the operation part 516 are two components, and the cleaning device 5c”’ can comprise the operation part 516, which is connected to the cleaning member 510c. The user can push or pull the operation part 516, so as to make the cleaning member 510c reciprocate in the filter cavity 53.

[0172] As shown in FIG. 12, the first filter member 52 (filter cavity 53) is provided with a sliding groove 56 above the first filter member 52 (filter cavity 53) (in the middle of the blocking member 51). The sliding groove 56 is arranged along the axial direction of the first filter member 52 (filter cavity 53), and can guide the reciprocating movement of the cleaning member 510c. The operation part 516 reciprocates in the sliding groove 56, so that the user can manually operate the operation part 516 outside the sliding groove 56, so as to make the cleaning member 510c reciprocate in the sliding groove 56, that is, the cleaning member 510c can reciprocate in the first filter member 52 (filter cavity 53).

[0173] The operation part 516 can be partially arranged outside the filter cavity 53 through the sliding groove 56, so that the user can conveniently hold and operate the operation part 516.

[0174] In order to make the operation part 516 slide smoothly in the sliding groove 56, a lubricating layer can be arranged on the side wall of the sliding groove 56. According to an embodiment of the present disclosure, the lubricating layer can be coated on the side wall of the sliding groove 56. According to another embodiment of the present disclosure, the part of the filter cavity 53 where the sliding groove 56 is arranged can be made of self-lubricating material.

[0175] The lubricating layer can reduce the friction between the operation part 516 and the sliding groove 56, so as to make the operation part 516 slide smoothly in the sliding groove 56.

[0176] In some embodiments, as shown in FIG. 13, the operation part 516 of the cleaning member 510c extending out of the first filter member 52 has a circular protrusion, so as to facilitate the user to operate. In another embodiment, the protrusion can also have other regular or irregular shapes, such as a square shape, a star shape, etc.

[0177] As known from the above, the part of the operation portion 516 protruding from the first filter element 52 is a circular protrusion, which can be defined as an operation section 5162. In addition, the operation portion also has a part penetrating the first filter element 52, which can be defined as a connecting section 5164. That is, the operation portion 516 can include the operation section 5162 and the connecting section 5164. One end of the connecting section 5164 is connected to the cleaning element 510c, and the other end of the connecting section 5164 is connected to the operation section 5162. The connecting section 5164 penetrates the sliding groove 56, and the operation section 5162 is located outside the filter cavity 53. A user can hold the operation section 5162 to make the cleaning element 510c reciprocate in the filter cavity 53. It should be noted that, although the sliding groove 56 is arranged in the middle of the clothes blocking element 51 in FIG. 12, it should be understood by those skilled in the art that the sliding groove 56 is arranged to facilitate the reciprocating movement of the cleaning element 510c in the first filter element 52 to clean the lint. It can be understood that the clothes blocking element 51 can also be replaced by other components or left empty. Therefore, when the cleaning device 5c is assembled in the clothes treatment apparatus, the operation portion 516 (operation section 5162) of the cleaning element 510c can protrude from the shell of the clothes treatment apparatus, or can be arranged in a storage groove arranged on the outer surface of the shell of the clothes treatment apparatus.

[0178] The present disclosure can control the reciprocating movement of the cleaning element 510c in the first filter element 52 manually, and push the lint to the lint collecting element 57 (not shown in the figure) to avoid the accumulation of the lint in the filter cavity 53.

[0179] The difference between the cleaning device 5b and the cleaning device 5c is that the cleaning device 5b pushes the lint from the filter cavity 53 to the lint collecting element 57 for collection and cleaning by the rotating cleaning element 510a, and the cleaning device 5c (which can include the cleaning device 5c', the cleaning device 5c'', the cleaning device 5c''', etc.) pushes the lint from the filter cavity 53 to the lint collecting element 57 for collection and cleaning by the reciprocating cleaning element 510b or the cleaning element 510c. Since the cleaning device 5c pushes the lint from the first filter element 52 to the lint collecting element 57 for collection and cleaning by the reciprocating cleaning element 510b or the cleaning element 510c, it can cancel the support element 518 for supporting the rotation of the cleaning element 510 in the cleaning device 5b, and can avoid the problem of the accumulation of the lint on the support element 518 in some embodiments of the present disclosure, and has better practicability.

[0180] In addition, it should be particularly pointed out that the cleaning element 510b or the cleaning element 510c in the cleaning device 5c can be a plate-shaped structure, which can be in elastic contact with the first filter element 52, and similar to the cleaning element 510a in the cleaning device 5a, the cleaning element 510b or the cleaning element 510c can also be provided with the above-mentioned reinforcing portion 514 at the edge, and according to the shape of the cleaning element 510b or the cleaning element 510c, the corresponding setting can be made, which will not be described here again.

[0181] The applicant finds that although the cleaning device 5 described in each of the above embodiments can remove most of the lint in the air flow, part of the lint still enters the air flow circulation path downstream of the first filter element 52. After the clothes treatment equipment works for a long time, there is still a risk that the air flow circulation path and the inside of the clothes treatment equipment are blocked by lint, which affects the circulation of the air flow and then affects the drying effect.

[0182] The entry of the lint into the air flow circulation path downstream of the first filter element 52 refers to the entry of the lint into the air outlet channel 13 and then into the air flow circulation path.

[0183] Based on the above technical problems, the present disclosure provides a cleaning device 5d, which aims to further solve the technical problems of the air outlet channel 13 being blocked by lint, affecting the circulation of the air flow and the drying effect. The installation method and detailed structure of the cleaning device 5d will be described in detail below in combination with FIGS. 14-18.

[0184] FIG. 14 is a structural schematic diagram of a cleaning device 5d with a secondary filtering function, and FIG. 15 is an exploded schematic diagram of the cleaning device 5d of FIG. 14. The cleaning device 5d is one of the cleaning devices 5. As shown in FIGS. 14 and 15, the cleaning device 5d includes a first filter element 52 and a second filter element 59. The first filter element 52 is configured to allow the air flow to pass through, and in the process of the air flow passing through the first filter element 52, the first filter element 52 filters and collects the lint in the air flow. The second filter element 59 is arranged downstream of the first filter element 52 in the direction of the air flow, and can not have a connection relationship with the first filter element 52. Since the cleaning device 5d is provided with the second filter element 59 downstream of the first filter element 52 for collecting the lint in the air flow, a structure for secondary filtering of the air flow is formed, which further reduces the probability of the air outlet channel 13 shown in FIG. 2 being blocked by the lint, makes the air flow circulation smooth, and improves the drying efficiency.

[0185] The second filter element 59 arranged downstream of the first filter element 52 in the direction of the air flow means that the second filter element 59 is arranged on the side of the first filter element 52 having the air outlet portion 52b.

[0186] The second filter 59 can be combined with the first filter 52 of any one of the aforementioned cleaning devices 5a-5c to form a cleaning device 5d, and unless otherwise specified, the structure and function of the first filter 52 in the cleaning device 5d are substantially the same as those in the aforementioned cleaning devices 5a-5c, and thus reference can be made to the corresponding drawings and descriptions, which will not be repeated here.

[0187] As shown in FIGS. 14 and 15, the cleaning device 5d can further include a containing body 50 provided with a containing cavity 501 capable of containing at least the first filter 52 and the second filter 59 of the cleaning device 5d, so that the first filter 52 and the second filter 59 are assembled in the containing body 50.

[0188] As shown in FIGS. 14 and 15, the containing cavity 501 can be provided through, and has opposite air inlet side 502 and air outlet side 503. The airflow passes through the first filter 52 and the second filter 59 in sequence from the air inlet side 502, and is discharged from the air outlet side 503 of the containing cavity 501 after being filtered by the first filter 52 and the second filter 59 to collect the dander carried in the airflow. In some embodiments, the first filter 52 can be assembled to the containing cavity 501 by clamping, bonding, or lapping the connecting member (support frame) of the first filter 52 to the containing cavity 501, and to improve the sealing between the first filter 52 and the containing body 50, a sealing gasket (not shown) can be provided between the support frame 52c and the containing cavity 501.

[0189] The air inlet side of the containing cavity 501 refers to the side of the containing cavity 501 where the airflow enters the containing cavity 501. Since the airflow needs to enter the containing cavity 501, an inlet communicating with the containing cavity 501 needs to be provided on the containing cavity 501, i.e., a cavity air inlet is provided on the containing cavity 501, and the side of the containing cavity 501 where the cavity air inlet is provided is the aforementioned air inlet side. Similarly, the air outlet side of the containing cavity 501 refers to the side of the containing cavity 501 where the airflow flows out of the containing cavity 501. Since the airflow needs to flow out of the containing cavity 501, an outlet communicating with the containing cavity 501 needs to be provided, i.e., a cavity air outlet is provided on the containing cavity 501, and the side of the containing cavity 501 where the cavity air outlet is provided is the aforementioned air outlet side.

[0190] FIG. 16 is a structural schematic diagram of the second filter 59 in FIG. 14, and FIG. 17 is an assembly schematic diagram of the second filter 59 shown in FIG. 16 on the containing body 50. As shown in FIGS. 14-17, the second filter 59 has a filter space 596 and a filter air inlet 597 and a filter air outlet 598 in communication with the filter space 596, the filter air inlet 597 is arranged towards the first filter 53 and in communication with the air outlet 52b of the first filter 53, air flow enters the filter space 596 through the filter air inlet 597 and is discharged from the filter space through the filter air outlet 598. The filter air outlet 597 can be arranged on the bottom wall of the second filter 59 away from the filter air inlet 597, or can be arranged on the side wall of the second filter 59, and the specific position of the filter air outlet 597 can not be limited.

[0191] The opening side of the second filter 59 is provided with a first connecting part 591, and a second connecting part 504 is arranged on the side wall of the containing cavity 501, the first connecting part 591 connects the second connecting part 504 to realize the assembly of the second filter 59 on the containing body 50. As shown in FIGS. 14-17, an embodiment of the present disclosure is to arrange an arc-shaped groove or an arc-shaped rib protruding on the inner wall of the containing cavity 501 as the above-mentioned second connecting part 504, so that the second connecting part 504 is clamped with the first connecting part 591.

[0192] The opening side of the second filter 59 refers to the side where the filter air inlet 597 is arranged, and also refers to the side close to the first filter 53.

[0193] As shown in FIG. 16, the first connecting part 591 can be a connecting frame, the connecting frame has a protruding part 5911 protruding from the second filter 59, the protruding part 5911 is matched with the shape of the second connecting part 504, and the protruding part 5911 is assembled in the second connecting part 504 to arrange the second filter 59 in the containing body 50. The protruding part 5911 can be assembled in the second connecting part 504 by clamping, bonding or screwing, etc., and the present disclosure does not limit this.

[0194] As shown in FIG. 16, a plurality of support rods 593 can be arranged at intervals on the opening side of the second filter 59 to ensure the size of the opening side of the second filter 59, prevent deformation, and improve the assembly efficiency of the second filter 59.

[0195] As can be seen from the above, a plurality of support rods 593 can be arranged at intervals on the opening side of the second filter 59, the support part 594 is used to connect the second filter 59 on both sides of the filter air inlet 579, and is used to support the second filter 59 on both sides of the filter air inlet to prevent the problem that the filter air inlet 597 becomes smaller due to the deformation of the second filter 59, and to improve the assembly efficiency of the second filter 59, and also to improve the air intake of the filter space.

[0196] According to an embodiment of the present disclosure, the second filter 59 is at least partially flexible, for example, the second filter 59 can be a dust bag structure. In an embodiment, the second filter 59 has heat and moisture resistance while having a filtering function. According to another embodiment of the present disclosure, the second filter 59 can also be a rigid material, and the second filter 59 is provided with a grid-shaped distribution of filter holes to filter the hair in the air flow.

[0197] The second filter 59 provided with a grid-shaped distribution of filter holes can be provided with a grid-shaped structure on the filtered air outlet 597.

[0198] However, the applicant found that when the air flow flows through the containing cavity 501 of the containing body 50, due to the fluid pressure of the air flow, the side wall of the flexible second filter 59 is easily extended to the side wall of the containing cavity 501, so that the air flow can only flow out from the bottom of the second filter 59 between the side walls of the containing cavity 501, affecting the flow efficiency of the air flow. The following will be further illustrated by FIG. 18 how to expand the second filter 59.

[0199] FIG. 18 is a schematic view of part of the second filter 59 in FIG. 16. As shown in FIG. 18, the first expansion member 594 can be arranged in the second filter 59 to at least partially expand the second filter 59, while expanding the contact area of the second filter 59 with the air flow, avoiding the flexible second filter 59 adhering or partially adhering to the inner wall of the containing cavity 501, affecting the ventilation effect.

[0200] As can be seen from the above, the first expansion member 594 is arranged in the second filter 59, that is, the first expansion member 594 is arranged in the filtering space 596. The first expansion member 594 can support the second filter 59 from the inside of the second filter 59, can expand the second filter 59 as much as possible, can increase the contact area of the second filter 59 with the air flow, and improve the filtering effect. Since the second filter 59 is expanded as much as possible, the filtering space 596 ensures sufficient capacity, so that more air flow can enter the filtering space 596, which can avoid the flexible second filter 59 adhering or partially adhering to the inner wall of the containing cavity 501 under the influence of the air flow, and can improve the air intake of the filtering space 596.

[0201] As shown in FIG. 18, specifically, the first extending member 594 includes an extending portion 5941, and the extending portion 5941 of the first extending member 594 is arranged to have an included angle with the running direction of the air flow. As long as the extending portion 5941 of the first extending member 594 is not arranged along the inner wall of the accommodating cavity 501 in the running direction of the air flow, the second filter member 59 can be partially but not completely supported to the inner wall of the accommodating cavity 501, so as to avoid that the flexible second filter member 59 is attached to the inner wall of the accommodating cavity 501 and the inner wall of the accommodating cavity 501 affects the ventilation efficiency. According to an embodiment of the present disclosure, as shown in FIG. 18, the extending portion 5941 of the first extending member 594 can be arranged perpendicularly to the running direction of the air flow, so as to maximize the improvement of the self-attachment of the second filter member 59 or the attachment of the second filter member 59 to the inner wall of the accommodating cavity 501, so as to ensure the filtering function of the second filter member 59 and the ventilation effect as much as possible. According to an embodiment of the present disclosure, the extending portion 5941 of the first extending member 594 can also be arranged to be inclined to the running direction of the air flow, so as to improve the self-attachment of the second filter member 59 or the attachment of the second filter member 59 to the inner wall of the accommodating cavity 501, and the present disclosure does not limit this.

[0202] The first extending member 594 can be arranged to be V-shaped or U-shaped, and the two ends of the extending member 594 can be respectively abut against the inner edge of the first connecting portion 591 shown in FIG. 16, or be overlapped on the upper surface of the first connecting portion 591, or be clamped to the outer edge of the first connecting portion 591. The middle portion of the extending member 594 is concave to form the above-mentioned extending portion 5941.

[0203] In some embodiments, the extending portion 5941 can include two, one end of the two extending portions 5941 is connected, and the other end is respectively connected with the second filter member 59, so that the first extending member 594 is approximately V-shaped or U-shaped. The end of the extending portion 5941 connected with the second filter member 59 can abut against the inner edge of the first connecting portion 591 shown in FIG. 16, or be overlapped on the upper surface of the first connecting portion 591, or be clamped to the outer edge of the first connecting portion 591.

[0204] As shown in FIG. 18, the first extending member 594 can be arranged to include a plurality of extending ribs arranged along the axial direction of the first filter member 52 (the filtering cavity 53), and the second filter member 59 is partially but not completely supported to the inner wall of the accommodating cavity 501 by the supporting effect of the extending ribs, so as to avoid that the flexible second filter member 59 is attached to the inner wall of the accommodating cavity 501 and affects the ventilation efficiency.

[0205] That is, in other embodiments, the first extension 594 can be provided in multiple numbers, and the multiple first extensions 594 can be arranged in the filter space 596 along the axial direction of the first filter 52 (filter cavity 53) at intervals. By the support of the multiple first extensions 594, different positions of the second filter 59 can be expanded, so that the second filter 59 is not in contact with the inner wall of the containing cavity 501 when expanded, to avoid the flexible second filter 59 adhering to the inner wall of the containing cavity 501 and affecting the ventilation efficiency.

[0206] As shown in FIGS. 16-18, in an embodiment, the second filter 59 further comprises a second extension 592 made of hard material, which has the function of air permeability and is arranged at the bottom or middle position of the second filter 59 to further expand the second filter 59.

[0207] In order to avoid the side surface of the flexible second filter 59 extending to the side wall of the containing cavity 501 and affecting the flow efficiency of the air flow, the first extension 594 and the second extension 592 are used to expand the second filter 59, but a gap is formed between the second filter 59 and the side wall of the containing cavity 501, so that the air flow can pass through the side surface and the bottom surface of the second filter 59 at the same time, and the transmission efficiency of the air flow is improved.

[0208] In other embodiments, as shown in FIG. 15, in order to form a gap between the side surface of the second filter 59 and the containing cavity 501, in an embodiment, a plurality of flow guide protrusions 505 as shown in FIG. 15 can be arranged on the side wall of the containing cavity 501. The flow guide protrusions 505 protrude from the side wall of the containing cavity 501, and the outer surface of the second filter 59 can be in contact with the plurality of flow guide protrusions 505. The plurality of flow guide protrusions 505 can further form a gap between the second filter 59 and the side wall of the containing cavity 501, and improve the ventilation effect.

[0209] That is, the plurality of flow guide protrusions 505 can also support the second filter 59 from the outside of the filter space 596, and a gap is formed between the outer surface of the second filter 59 and the side wall of the containing cavity 501, to improve the ventilation effect.

[0210] All the flow guide protrusions 505 can be integrally formed on the side wall of the containing cavity 501, and it is best to arrange them along the direction of the air flow to avoid blocking the air flow. However, if the best implementation effect is not pursued, part or all of the flow guide protrusions 505 can also have an angle with the direction of the air flow, and the present disclosure does not limit this.

[0211] According to another embodiment of the present disclosure, a plurality of flow guide protrusions 505 can also be arranged on the outer surface of the second filter 59 (arranged outside the filtering space 596). When the air flow passes through the second filter 59, the second filter 59 is inflated, the flow guide protrusions 505 on the outer surface of the second filter 59 are in contact with the side wall of the containing cavity 501, and a gap is formed between the second filter 59 and the side wall of the containing cavity 501 for the air flow to pass through. In addition, although the flow guide protrusions 505 shown in FIG. 15 are in the shape of a long strip, they can also be in the shape of dots, blocks, etc., and the present disclosure does not limit this.

[0212] In an embodiment of the present disclosure, the containing body 50 can constitute the air inlet 12 shown in FIG. 1, and the inner side wall of the containing body 50 (the side wall of the containing cavity 501) is the inner side wall of the air inlet 12. In another embodiment of the present disclosure, the containing body 50 is arranged inside the air inlet 12 shown in FIG. 1, and the air flow enters the containing body 50 from the air inlet 12. In another embodiment of the present disclosure, the containing body 50 can also be connected to the side wall of the air inlet 12, and the air flow enters the containing body 50 from the air inlet 12.

[0213] It should be noted that in other embodiments, the first filter 52 of the cleaning device 5d can also be replaced by other types of filter structures, such as filter structures without cleaning function, or filter structures that achieve cleaning function in other ways, etc., and the present disclosure does not limit this.

[0214] In summary, the present disclosure provides a laundry treatment apparatus including the above-described cleaning device 5. In an embodiment of the present disclosure, the cleaning device 5 is any one of the cleaning device 5a, the cleaning device 5b, the cleaning device 5c, and the cleaning device 5d. In another embodiment of the present disclosure, the cleaning device 5 is a combination of any one of the cleaning device 5a, the cleaning device 5b, and the cleaning device 5c and the second filter 59. In another embodiment of the present disclosure, the cleaning device 5 is the second filter 59.

[0215] The laundry treatment apparatus (a clothes dryer or a washer-dryer) provided by the present disclosure can avoid the influence of lint on the cleanliness of the air flow, maintain the smoothness of the air flow under long-term circulation, and improve the drying effect; and / or can perform secondary filtration on the air flow, further reduce the lint in the air flow, and improve the drying effect.

[0216] However, the applicant found that if the above-described cleaning device 5 is arranged below the air inlet 12 of the laundry treatment apparatus, the space below the air inlet 12 is limited, and because the air flow always needs to flow through the cleaning device 5, the air flow circulation can be affected.

[0217] Therefore, the present disclosure further moves the first filter 52 of the cleaning device 5 to the door body 2 to ensure the smoothness of the air flow to a certain extent.

[0218] FIG. 19 is a structural schematic view of the door body 2 with the first filter 52, and FIG. 20 is an exploded schematic view of the door body 2 shown in FIG. 19. In combination with FIGS. 1, 2, 19, and 20, the laundry treating apparatus provided by the present disclosure includes the housing 1, the door body 2, the drum 3, and the drop port 11. The housing 1 is provided with the drop port 11, the drum 3 is disposed in the housing 1, and the door body 2 is connected to the housing 1 to open and close the drop port 11. The door body 2 is provided with the air inlet portion 21 and the air outlet portion 22, the air inlet portion 21 is communicated with the drum 3, and the first filter 52 is disposed in the door body 2 and arranged in the path of the airflow to clean the lint in the airflow.

[0219] The laundry treating apparatus provided by the present disclosure, since the door body 2 is provided with the air inlet portion 21 and the air outlet portion 22, the air outlet portion 21 is communicated with the drum 3, and the airflow discharged from the drum 3 can enter the door body 2 through the air inlet portion 21, since the first filter 52 is disposed in the path of the airflow in the door body 2, the first filter 52 can clean the lint in the airflow flowing into the door body 2 to form a clean airflow. The present disclosure, since the first filter 52 is arranged in the door body 2, can utilize the existing space while ensuring smooth airflow, and has good practicability.

[0220] As shown in FIG. 1, the airflow cleaned by the first filter 52 flows into the air inlet 12 through the air outlet portion 22 at the bottom of the door body 2 and circulates into the drum 3 through the air outlet channel 13. Among them, the air inlet 12 of the housing 1 is arranged below the door body 2 in the closed state to be docked with the air outlet portion 22 arranged at the bottom of the door body 2 to receive the airflow flowing through the first filter 52 of the door body 2. The specific technical solutions of the door body 2 with the first filter 52 will be described in detail below by means of FIGS. 19 to 27.

[0221] As shown in FIGS. 19 and 20, according to an embodiment of the present disclosure, at least part of the inner side of the door body 2 (towards the side of the drum 3) can be provided with a plurality of first through holes 21a distributed in a grid shape, and / or at least part of the circumferential side of the door body 2 can be provided with a plurality of second through holes 21b distributed in a grid shape.

[0222] In some embodiments, since the air inlet portion 21 is composed of a plurality of through holes with small aperture, it can avoid the clothes in the drum 3 from entering the first filter 52 while avoiding the flow, thereby playing the role of the aforementioned clothes blocking member 51 to block clothes and intake air. Therefore, the first filter 52 arranged in the door body 2 does not need to be configured with the aforementioned clothes blocking member 51.

[0223] As shown in FIG. 19 and FIG. 20, in a preferred embodiment of the present disclosure, the grid-shaped air inlet 21 is arranged above the first filter 52, so that the air flow mixed with lint is input to the first filter 52 from the air inlet 21 above the first filter 52, and the clean air flow is output from the air outlet 52b at the bottom of the first filter 52. In this way, the path of the air flow is limited, which can improve the cleaning efficiency to a certain extent.

[0224] In other words, in this way, the flow direction of the air flow entering the first filter 52 from the air inlet 21 will not change substantially, and the flow rate of the air will not be slowed down, so that the air flow can enter the first filter 52 as soon as possible, which can reduce the filtering time to a certain extent and improve the cleaning efficiency.

[0225] However, in another embodiment of the present disclosure, the grid-shaped air inlet 21 is arranged on any side of the first filter 52, and the air flow mixed with lint can also be guided to the first filter 51. The present disclosure does not limit the relative position of the air inlet 21 and the first filter 52.

[0226] As shown in FIG. 20, in an embodiment, the door body 2 includes a first door body 23 and a second door body 24 which are detachably connected. After the clothes treatment apparatus has been operated for a long period of time, the first door body 23 can be detached from the door body 2, so that the first door body 23 and the first filter 52 can be maintained. After the first door body 23 is detached from the second door body 24, the entire cleaning device 5 or a part of the cleaning device can be replaced, or the first door body 23 and the first filter 52 can be directly cleaned to remove lint and the like. In an embodiment, the plurality of first through holes 21a and second through holes 21b arranged in a grid pattern can be arranged in the first door body 23. The specific structure and function of the first door body 23 and the second door body 24 will be described in detail below with reference to FIG. 21 to FIG. 23.
