Description

Technical Field

[0001] The present invention belongs to the technical field of filtration, and particularly provides a filtration device and a clothes drying device. Background Art

[0002] A filtration device is a device that can filter impurities (such as dust, lint, etc.), and it is widely used in various fields such as production and processing, washing and care, dust removal and purification, and environmental temperature regulation. Existing filtration devices are generally fixed, that is, their filtration components (such as filter meshes, filter plates, filter covers, etc.) are fixed in the channels through which a flowing medium (such as air, water, etc.) flows, and the impurities in the flowing medium are filtered by the filtration components.

[0003] Taking a clothes drying device as an example, a clothes drying device is a device that can dry clothes. Existing clothes drying devices include drum dryers, cabinet dryers, drawer dryers, etc. In a drum dryer, since lint appears during the process of drying clothes, it is necessary to filter and collect the lint. The traditional lint collection method is to install a lint filter mesh in the air duct of the drum dryer, and the lint is filtered and collected through the lint filter mesh. The drawback of this setting method is that the lint filter mesh in the drum dryer will be covered with lint in a very short time, and users have to clean the lint filter mesh every once in a while. When cleaning, it is necessary to disassemble the lint filter mesh from the air duct, which is very inconvenient, and the filtration area of the lint filter mesh is limited, and the filtration effect is not good, greatly reducing the user experience.

[0004] Therefore, there is a need in the art for a new filtration device and a corresponding clothes drying device to solve the above problems. Summary of the Invention

[0005] In order to solve the above problems in the prior art, that is, to solve the problems that when the existing filtration device is fixed, users need to often clean it and the filtration effect is not good, the present invention provides a filtration device, which includes a support mechanism, an annular filtration component, a lint cleaning component, and a lint collection component. The annular filtration component is arranged to be able to rotate relative to the support mechanism under the action of an external force. The lint cleaning component and the lint collection component are both arranged on the support mechanism. During the rotation of the annular filtration component, the lint cleaning component can clean the lint on the annular filtration component and the lint collection component can collect the cleaned lint.

[0006] In a preferred technical solution of the above filtration device, the annular filtration component includes an annular filtration support and an annular filter mesh arranged on the annular filtration support. The annular filtration support is arranged to be able to rotate relative to the support mechanism under the action of an external force.

[0007] In a preferred technical solution of the above filtering device, the annular filter screen includes a plurality of arc-shaped filter screens, and the arc-shaped filter screens are clamped on the annular filter support.

[0008] In a preferred technical solution of the above filtering device, the lint cleaning member includes a connecting rod and a scraper connected to each other. The connecting rod is clamped on the support mechanism, and the scraper is arranged close to or in contact with the annular filtering member.

[0009] In a preferred technical solution of the above filtering device, the lint collection member includes a lint collection box, the lint collection box is detachably connected to the support mechanism, and the lint collection port of the lint collection box is located below the lint cleaning member.

[0010] In a preferred technical solution of the above filtering device, a holding structure is formed on the lint collection box.

[0011] In a preferred technical solution of the above filtering device, the lint collection port is arranged to gradually open in the direction close to the lint cleaning member.

[0012] In a preferred technical solution of the above filtering device, the lint collection member is located on the left or right part of the support mechanism.

[0013] On the other hand, the present invention also provides a clothes drying device, and the clothes drying device includes the above filtering device.

[0014] In a preferred technical solution of the above clothes drying device, the clothes drying device includes a box body and a clothes drying cylinder arranged in the box body. A clothes feeding port communicating with the inside of the clothes drying cylinder is arranged on the front panel of the box body. The support mechanism is arranged on the front panel, and the annular filtering member is connected to the clothes drying cylinder and can rotate together with the clothes drying cylinder.

[0015] Those skilled in the art can understand that in a preferred technical solution of the present invention, the filtering device includes a support mechanism, an annular filtering member, a lint cleaning member and a lint collection member. The annular filtering member is arranged to be able to rotate relative to the support mechanism under the action of an external force. The lint cleaning member and the lint collection member are both arranged on the support mechanism. During the rotation of the annular filtering member, the lint cleaning member can clean the lint on the annular filtering member and the lint collection member can collect the cleaned lint. Through such a setting, that is, the annular filtering member is set to be rotary, and when the annular filtering member rotates relative to the support mechanism under the action of an external force, the lint cleaning member can clean the lint on the annular filtering member and collect it in the lint collection member. In this way, the user does not need to clean the annular filtering member frequently, and the area of the annular filtering member is large enough to improve the filtering effect and greatly enhance the user experience.

[0016] Furthermore, the annular filtering member includes an annular filtering support and an annular filtering net disposed on the annular filtering support. The annular filtering support is configured to be rotatable relative to the support mechanism under the action of an external force. With such a setting, it can be ensured that when the annular filtering support rotates relative to the support mechanism under the action of an external force, the annular filtering net can also rotate, enabling the annular filtering net to fully filter the lint, and the lint cleaning member can clean the lint on the annular filtering net thoroughly. Users do not need to frequently clean the annular filtering net, greatly enhancing the user experience.

[0017] Furthermore, the annular filtering net includes a plurality of arc-shaped filtering nets. The arc-shaped filtering nets are clamped on the annular filtering support. With such a setting, it is convenient for the disassembly of the annular filtering net, and the arc-shaped filtering nets can be disassembled individually. On the one hand, it is convenient for the individual cleaning of the arc-shaped filtering nets. On the other hand, when an arc-shaped filtering net is damaged, only this damaged arc-shaped filtering net needs to be replaced individually, without replacing the entire annular filtering net, simplifying the operation of maintenance personnel and reducing the maintenance cost for users, further enhancing the user experience.

[0018] Furthermore, by clamping the connecting rod on the support mechanism, it is possible to replace the scraper in a timely manner when the scraper is damaged or the sharpness of the scraper blade is poor, and it is convenient for users to perform the replacement operation, further enhancing the user experience.

[0019] Furthermore, the lint collection box is detachably connected to the support mechanism, enabling users to quickly remove the lint collection box when the lint in the lint collection box is full, so as to clean the lint collection box in a timely manner, further enhancing the user experience.

[0020] Furthermore, a gripping structure is formed on the lint collection box. With such a setting, users can easily remove the lint collection box through the gripping structure, making it more convenient for the disassembly of the lint collection box, further enhancing the user experience.

[0021] Furthermore, the lint collection port is gradually widened along the direction close to the lint cleaning member. With such a setting, when the lint on the annular filtering member is cleaned by the lint cleaning member, it is easier to enter the lint collection box, facilitating the collection of lint, improving the lint collection effect, and further enhancing the user experience.

[0022] Furthermore, the lint collection member is located on the left or right side of the support mechanism. With such an arrangement, the vertical space can be fully utilized. Since the lint cleaned by the lint cleaning member will move from top to bottom under the action of gravity, setting the lint collection member on the left or right side of the support mechanism can provide space support for designing the lint collection member into a "tall and thin" structure (i.e., the lint collection member has a narrow width but a high height), thereby improving the lint collection effect.

Detailed Description of the Invention

[0035] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

This is only for convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0037] In addition, it should also be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "set", "installed", "connected", "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0038] Based on the problems pointed out in the background art that when the existing filtering device is fixed, users need to clean it frequently and the filtering effect is not good, the present invention provides a filtering device and a clothes drying device, aiming to enable users not to clean the filtering device frequently, increase the filtering area, improve the filtering effect, and greatly enhance the user experience.

[0039] It should be pointed out that the filtering device of the present invention can be applied to various fields such as production and processing, washing and care, dust removal and purification, and environmental temperature regulation. The technical solutions of the present invention will be described in more detail below by combining the structure of the filtering device itself and the use of the filtering device of the present invention in a clothes drying device in the field of washing and care.

[0040] First, the structure of the filtering device of the present invention itself will be described.

[0041] Specifically, as Figure 1As shown, the filtering device includes a support mechanism 1, an annular filtering member 2, a lint cleaning member, and a lint collection member. The annular filtering member 2 is arranged to be rotatable relative to the support mechanism 1 under the action of an external force. Both the lint cleaning member and the lint collection member are arranged on the support mechanism 1. During the rotation of the annular filtering member 2, the lint cleaning member can clean the lint on the annular filtering member 2, and the lint collection member can collect the cleaned lint. Among them, the support mechanism 1 can adopt the structure of a single support member, such as a support frame, a support plate, or a support seat, etc. Of course, the support mechanism 1 can also adopt a structure combined with multiple support members, such as multiple support frames, multiple support plates, multiple support seats, a combination of a support frame and a support plate, a combination of a support frame and a support seat, or a combination of a support plate and a support seat, etc. Those skilled in the art can flexibly set the specific structure of the support mechanism 1 in practical applications. Such adjustments and changes to the specific structure of the support mechanism 1 do not constitute a limitation to the present invention and should all be limited within the protection scope of the present invention. The annular filtering member 2 can adopt the structure of an annular filter net or a structure combined with an annular filter support and an annular filter net. Those skilled in the art can flexibly set the specific structure of the annular filtering member 2 in practical applications. Such adjustments and changes to the specific structure of the annular filtering member 2 do not constitute a limitation to the present invention and should all be limited within the protection scope of the present invention. The lint cleaning member can adopt the structure of a scraper or the structure of a brush. Those skilled in the art can flexibly set the specific structure of the lint cleaning member in practical applications. Such adjustments and changes to the specific structure of the lint cleaning member do not constitute a limitation to the present invention and should all be limited within the protection scope of the present invention. The lint collection member can adopt the structure of a lint collection box or the structure of a lint collection groove. Those skilled in the art can flexibly set the specific structure of the lint collection member in practical applications. Such adjustments and changes to the specific structure of the lint collection member do not constitute a limitation to the present invention and should all be limited within the protection scope of the present invention. In addition, the annular filtering member 2 is connected to an external rotary driving member, and under the force applied by the rotary driving member, the annular filtering member 2 rotates relative to the support mechanism 1. Taking the drying drum 3 of a clothes dryer as the rotary driving member as an example, the drying drum 3 can be connected to the annular filtering member 2 so that the drying drum 3 serves as an external force driving source for the annular filtering member 2 to rotate relative to the support mechanism 1.

[0042] Preferably, as Figures 1 to 3As shown, the annular filtering member 2 includes an annular filtering support 21 and an annular filtering net 22 arranged on the annular filtering support 21. The annular filtering support 21 is arranged to be able to rotate relative to the support mechanism 1 under the action of an external force. The annular filtering support 21 can be slidably connected to the support mechanism 1, so that the annular filtering support 21 can rotate relative to the support mechanism 1 driven by an external force. Of course, the annular filtering support 21 can also be in a non-contact manner with the support mechanism 1, so that the annular filtering support 21 can rotate relative to the support mechanism 1 driven by an external force. The annular filtering net 22 can be integrally provided or detachably connected to the annular filtering support 21. Of course, preferably, the annular filtering net 22 is detachably connected to the annular filtering support 21 to facilitate the user to detach the annular filtering net 22 from the annular filtering support 21. In a more preferred case, the annular filtering net 22 includes a plurality of arc-shaped filtering nets, and the arc-shaped filtering nets are clamped on the annular filtering support 21. The plurality of arc-shaped filtering nets together form the annular filtering net 22. The number of arc-shaped filtering nets can be 2, 3, 4 or more. In addition, the arc lengths of all the arc-shaped filtering nets can be set to be all equal, or all unequal, or some are equal and some are unequal. Those skilled in the art can flexibly set the number and size of the arc-shaped filtering nets in practical applications. Such adjustments and changes to the number and size of the arc-shaped filtering nets do not constitute a limitation to the present invention and should all be limited within the protection scope of the present invention. The clamping manner between the arc-shaped filtering net and the annular filtering support 21 can be by snap connection, or by claw connection, or by rib connection. In the structure shown in the figure, an annular groove is formed on the annular filtering support 21, and a plurality of ribs are arranged on the edge of the annular groove, and the plurality of ribs clamp the arc-shaped filtering net in the annular groove. Those skilled in the art can flexibly set the clamping manner between the arc-shaped filtering net and the annular filtering support 21 in practical applications. Such adjustments and changes to the clamping manner between the arc-shaped filtering net and the annular filtering support 21 do not constitute a limitation to the present invention and should all be limited within the protection scope of the present invention.

[0043] Preferably, as Figure 1As shown in the figure, the lint cleaning member includes a connecting rod 41 and a scraper 42 which are connected. The connecting rod 41 is clamped on the support mechanism 1, and the scraper 42 is arranged close to or in contact with the annular filter member 2. The connecting rod 41 and the scraper 42 can be integrally arranged, or can be detachably connected (such as by clamping, screwing and / or bonding, etc.). The connecting rod 41 can be connected to the support mechanism 1 through a buckle, can also be connected to the support mechanism 1 through a catch, and can also be connected to the support mechanism 1 through a claw. Those skilled in the art can flexibly set the specific clamping method between the connecting rod 41 and the support mechanism 1 in practical applications. The scraper 42 can be arranged in contact with the annular filter member 2, or can be arranged close to the annular filter member 2 (that is, there is a gap with the annular filter member 2). It should be noted that when the scraper 42 is arranged with a gap from the annular filter member 2, it is necessary to ensure that the distance between the scraper 42 and the annular filter member 2 can enable the scraper 42 to scrape off the lint on the annular filter member 2. When the annular filter member 2 includes an annular filter support 21 and an annular filter net 22 arranged on the annular filter support 21, the scraper 42 is arranged close to or in contact with the annular filter net 22.

[0044] Preferably, as Figures 1 to 3 shown in the figure, the lint collection member includes a lint collection box 5. The lint collection box 5 is detachably connected to the support mechanism 1, and the lint collection port of the lint collection box 5 is located below the lint cleaning member. The lint collection box 5 and the support mechanism 1 can be connected by means of screwing, clamping and / or bonding, etc. Those skilled in the art can flexibly set the specific connection method between the lint collection box 5 and the support mechanism 1 in practical applications. The lint collection port of the lint collection box 5 is located below the lint cleaning member. Through such a setting, after the lint cleaning member scrapes off the lint on the annular filter member 2, the lint can directly fall into the lint collection box 5. For example, taking the structure in which the aforementioned lint cleaning member includes a connecting rod 41 and a scraper 42 and the annular filter member 2 includes an annular filter support 21 and an annular filter net 22 as an example, during the process of driving the annular filter support 21 to rotate by an external force, the annular filter net 22 also rotates, and the scraper 42 scrapes off the lint on the annular filter net 22, and the lint enters the lint collection box 5 through the lint collection port under the action of its own gravity.

[0045] Preferably, as Figure 1 shown in the figure, a holding structure 51 is formed on the lint collection box 5. Among them, the purpose of setting the holding structure 51 is that the user can more smoothly disassemble the lint collection box 5 by operating the holding structure 51. The holding structure 51 can be a depression formed on the lint collection box 5. Of course, the holding structure 51 can also be a handle formed on the lint collection box 5. Those skilled in the art can flexibly set the specific structural form of the holding structure 51 in practical applications.

[0046] Preferably, asFigure 2 and 3 As shown in 3 , the lint collection port is gradually opened in the direction close to the lint cleaning member. Through such a setting, the lint cleaned by the lint cleaning member is more likely to enter the lint collection box 5. When the lint cleaning member adopts the combined structure of the aforementioned connecting rod 41 and the scraper 42, the lint collection port is gradually opened in the direction close to the scraper 42, that is, the lint collection port is gradually contracted in the moving and collecting direction of the lint. Those skilled in the art can flexibly set the opening area and opening angle of the lint collection port in practical applications, as long as it is ensured that the lint cleaned by the scraper 42 can enter the lint collection box 5.

[0047] Preferably, the lint collection member is located on the left or right of the support mechanism 1. Since the lint will move from top to bottom under its own gravity after being scraped off by the lint cleaning member, setting the lint collection member on the left or right of the support mechanism 1 can make full use of the vertical space. That is, the width of the lint collection member can be set to be relatively narrow and the height can be set to be relatively high, forming a "thin and tall" structure, so as to utilize the height space of the lint collection member to accommodate more lint, and thus greatly improve the lint collection effect.

[0048] Next, the filtering device of the present invention will be described in combination with a drying device. Among them, the drying device can be a drum dryer, a cabinet dryer, a drawer dryer, etc. Hereinafter, only the drum dryer will be used as an example for illustrative description.

[0049] The drum dryer can have a top-opening structure or a front-opening structure. Taking the drum dryer with a front-opening structure as an example, as Figures 4 to 10As shown, the drum dryer specifically includes a cabinet, a drying drum 3, and a filtering device. The drying drum 3 is arranged in the cabinet. The cabinet includes a front panel 6, and a clothing inlet communicating with the interior of the drying drum 3 is arranged on the front panel 6. The filtering device includes a support mechanism 1, an annular filtering member 2, a lint cleaning member, and a lint collecting member. The support mechanism 1 is arranged on the front panel 6. The annular filtering member 2 is arranged between the support mechanism 1 and the drying drum 3. Both the lint cleaning member and the lint collecting member are arranged on the support mechanism 1. The annular filtering member 2 is arranged to be able to rotate together with the drying drum 3. During the rotation of the annular filtering member 2, the lint cleaning member can clean the lint on the annular filtering member 2 and the lint collecting member can collect the cleaned lint. Among them, when the drum dryer adopts a single-drum structure, the drying drum 3 is this single drum, and the drying drum 3 can be directly connected to the annular filtering member 2. When the drum dryer adopts a double-drum structure, the drying drum 3 is the inner drum of the double drum. The inner drum is arranged in the outer drum, and the inner drum is connected to the driving motor and rotates relative to the outer drum under the driving action of the driving motor. The inner drum can be directly connected to the annular filtering member 2, and the inner drum drives the annular filtering member 2 to rotate when rotating.

[0050] Preferably, as Figures 8 to 10 shown, the annular filtering member 2 includes an annular filtering bracket 21 and an annular filter net 22 arranged on the annular filtering bracket 21. The annular filtering bracket 21 is fixedly connected to the drying drum 3, and the annular filtering bracket 21 can rotate relative to the support mechanism 1 driven by the drying drum 3. Among them, the annular filtering bracket 21 can be connected to the drying drum 3 by means of screwing, clamping, and / or bonding, etc. Those skilled in the art can flexibly set the connection method between the annular filtering bracket 21 and the drying drum 3 in practical applications. The annular filtering bracket 21 can be slidably connected to the support mechanism 1, so that the annular filtering bracket 21 can rotate relative to the support mechanism 1 driven by the drying drum 3. Of course, the annular filtering bracket 21 can also be in a non-contact manner with the support mechanism 1, so that the annular filtering bracket 21 can rotate relative to the support mechanism 1 driven by the drying drum 3.

[0051] Preferably, as Figures 7 to 10As shown, the support mechanism 1 includes a first support member 11 and a second support member 12 connected to each other. At least one of the first support member 11 and the second support member 12 is disposed on the front panel 6. The lint cleaning member and the lint collection member are both disposed on the second support member 12. The first support member 11 and the second support member 12 together form an annular cavity 13 that communicates the air duct of the drying device with the interior of the drying drum 3. The annular filter member 2 is connected to the drying drum 3 and at least a part of the annular filter member 2 is disposed in the annular cavity 13. Among them, it can be that the first support member 11 is separately disposed on the front panel 6, or the second support member 12 is separately disposed on the front panel 6, or the first support member 11 and the second support member 12 are simultaneously disposed on the front panel 6. The first support member 11 and the second support member 12 can be connected by means such as screwing, clamping and / or bonding. Those skilled in the art can flexibly set the connection method between the first support member 11 and the second support member 12 in practical applications. The first support member 11 and the second support member 12 can be structures such as a support plate, a support frame or a support rib. Those skilled in the art can flexibly set the specific structures of the first support member 11 and the second support member 12 in practical applications. Such adjustments and changes to the specific structures of the first support member 11 and the second support member 12 do not constitute a limitation to the present invention and should all be limited within the protection scope of the present invention. Below, taking the first support member 11 being separately disposed on the front panel 6 as an example, the technical solution of the present invention will be further elaborated.

[0052] In the above, the annular filter member 2 can be entirely disposed in the annular cavity 13 or partially disposed in the annular cavity 13. When the drum dryer dries clothes, the fan in the air duct operates, drawing the air in the drying drum 3 into the air duct. The air will flow through the annular cavity 13. At this time, the lint in the air will be filtered by the annular filter member 2, achieving the purpose of removing the lint in the air. The lint cleaning member and the lint collection member can be integrally disposed with the second support member 12 or detachably connected to the second support member 12. Of course, preferably, both the lint cleaning member and the lint collection member are detachably connected to the second support member 12, thereby facilitating the inspection, replacement and repair of the lint cleaning member and facilitating the cleaning, replacement and repair of the lint collection member. Those skilled in the art can flexibly set the specific connection methods between the lint cleaning member and the lint collection member and the second support member 12 in practical applications.

[0053] Preferably, as Figure 10As shown, the second support member 12 includes an annular support frame 121 connected to the first support member 11 and a mounting frame 122 provided on the annular support frame 121. Both the wire debris cleaning member and the wire debris collection member are provided on the mounting frame 122. The annular support frame 121 can be connected to the first support member 11 by means such as screwing, clamping, and / or bonding. The mounting frame 122 can be connected to the annular support frame 121 by means such as screwing, clamping, and / or bonding. Those skilled in the art can flexibly set the specific connection method between the annular support frame 121 and the first support member 11 and the specific connection method between the mounting frame 122 and the annular support frame 121 in practical applications. Among them, the mounting frame 122 can be set as a box-shaped structure or a groove-shaped structure, etc. Those skilled in the art can flexibly set the specific structure and shape of the mounting frame 122 in practical applications. In addition, the wire debris cleaning member and the wire debris collection member can be integrally provided with the mounting frame 122 or detachably connected to the mounting frame 122. Of course, preferably, both the wire debris cleaning member and the wire debris collection member are detachably connected to the mounting frame 122, so as to facilitate the inspection, replacement, and maintenance of the wire debris cleaning member and facilitate the cleaning, replacement, and maintenance of the wire debris collection member. Those skilled in the art can flexibly set the specific connection method between the wire debris cleaning member and the wire debris collection member and the mounting frame 122 in practical applications.

[0054] In a possible case, the mounting frame 122 includes side plates, a front plate, and a bottom plate. The side edges of the side plates are connected to the side edges of the front plate. The bottom edges of the side plates and the front plate are respectively connected to the two side edges of the front plate. The side plates, the front plate, and the bottom plate form a three-sided enclosed covering space for accommodating and clamping the wire debris cleaning member. A long strip-shaped depression is provided on the front plate, and a long strip-shaped protrusion matching the long strip-shaped depression is provided on the annular support frame 121. In the case of the assembly being completed, the long strip-shaped protrusion cooperates with the long strip-shaped depression to position the front plate, and thus position the mounting frame 122.

[0055] Preferably, as Figure 10 shown, the wire debris cleaning member includes a connecting rod 41 and a scraper 42 connected to each other. The connecting rod 41 is clamped on the mounting frame 122, and the scraper 42 is disposed close to or in contact with the annular filter member 2. The connecting rod 41 can be connected to the mounting frame 122 by a buckle, can also be connected to the mounting frame 122 by a hook, and can also be connected to the mounting frame 122 by a claw. Those skilled in the art can flexibly set the specific clamping connection method between the connecting rod 41 and the mounting frame 122 in practical applications. In a possible case, still taking the above-mentioned structure in which the mounting frame 122 includes side plates, a front plate, and a bottom plate as an example, two mounting strips screwed to the annular support frame 121 are extended on the side plates, and bayonets are formed on the mounting strips. Both ends of the connecting rod 41 are respectively clamped in the bayonets of the two mounting strips.

[0056] Preferably, asFigure 5 , 6 As shown in FIGS. 9 and 10, the lint collection member includes a lint collection box 5, which is detachably connected to the mounting bracket 122. At least a part of the lint collection box 5 is disposed in the annular cavity 13, and the lint collection port of the lint collection box 5 is located below the lint cleaning member. The lint collection box 5 and the mounting bracket 122 can be connected by means such as screwing, clamping, and / or bonding. Those skilled in the art can flexibly set the specific connection method between the lint collection box 5 and the mounting bracket 122 in actual applications. The lint collection box 5 can be entirely disposed in the annular cavity 13 or partially disposed in the annular cavity 13. In actual applications, preferably, the lint collection box 5 is entirely disposed in the annular cavity 13. By such a setting, the lint collection box 5 can be hidden in the support mechanism 1, and the user cannot observe the lint collection box 5 from the outside of the laundry inlet, improving the overall aesthetics of the tumble dryer. In addition, it also prevents the user from scraping the lint collection box 5 when loading clothes, avoiding damage to the clothes.

[0057] Preferably, as Figure 5 and 6 shown, a gripping structure 51 is formed on the rear outer wall of the lint collection box 5. Among them, the purpose of setting the gripping structure 51 is that the user can more smoothly remove the lint collection box 5 by operating the gripping structure 51. The gripping structure 51 can be a recess formed on the rear outer wall of the lint collection box 5. Of course, the gripping structure 51 can also be a handle formed on the rear outer wall of the lint collection box 5. Those skilled in the art can flexibly set the specific structural form of the gripping structure 51 in actual applications. In addition, the advantage of setting the gripping structure 51 on the rear outer wall of the lint collection box 5 is that the user cannot observe the gripping structure 51 from the outside of the laundry inlet. In actual applications, the user can reach the rear of the lint collection box 5 and then operate the gripping structure 51 to remove the lint collection box 5 from the mounting bracket 122, which is convenient for the user's operation while improving the aesthetics.

[0058] Preferably, as Figure 10As shown, the lint collecting member is located at the left or right part of the support mechanism 1. In practical applications, the front side of the support mechanism 1 is close to the door hinge and the door lock on the front panel 6. Since the door lock is larger in size and the door hinge is smaller in size, the lint collecting member can be arranged on the side close to the door hinge. For example, when the door lock is on the left side of the clothing inlet of the front panel 6 and the door hinge is on the right side, it is preferred to arrange the lint collecting member on the right side of the support mechanism 1. When the door lock is on the right side of the clothing inlet of the front panel 6 and the door hinge is on the left side, it is preferred to arrange the lint collecting member on the left side of the support mechanism 1. With such an arrangement, it is convenient to arrange the installation space of the door lock on the front panel 6, avoid interference with the lint collecting member, and avoid affecting the overall layout of the drum dryer. In addition, since the lint will move from top to bottom under the action of its own gravity after being scraped off by the lint cleaning member, arranging the lint collecting member on the left or right part of the support mechanism 1 can make full use of the vertical space of the drum dryer, that is, the width of the lint collecting member can be set to be narrower and the height can be set to be higher on the basis of not occupying the space of the clothing inlet as much as possible, forming a "thin and tall" structure, so as to use the height space of the lint collecting member to accommodate more lint. Compared with arranging the lint collecting member on the upper part of the front support and only being able to set the lint collecting member to a "flat and long" structure, arranging the lint collecting member on the left or right part of the support mechanism 1 can greatly improve the lint collection effect. In addition, in the present invention, the air duct can be located at the bottom of the support mechanism 1. For example, in the support mechanism 1 using the combination structure of the first support member 11 and the second support member 12, the air duct can be connected to the bottom of the annular cavity 13, and at the same time, a through hole structure is provided on the second support member 12 to connect the annular cavity 13 with the interior of the dryer drum 3. Of course, the air duct can also be located at other positions of the support mechanism 1, such as the left or right part of the support mechanism 1. Those skilled in the art can flexibly set the specific setting position of the air duct in actual applications. Such adjustment and change of the specific setting position of the air duct does not constitute a limitation of the present invention and should be limited within the scope of protection of the present invention.

[0059] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
