Description

Technical Field

[0001] The invention belongs to the technical field of clothes dryers, and in particular relates to a clothes dryer and a lint separation device thereof. Background Art

[0002] During the operation of the dryer, the fluff and lint on the clothes will inevitably flow with the drying air and be blocked by the lint filter and remain on the lint filter. As the dryer is used, the fluff and lint accumulate on the lint filter and block the flow of drying air, resulting in reduced drying efficiency and poor drying effect.

[0003] In order to solve this problem, the prior art usually sets the lint filter device as a detachable structure. After the dryer has been used for a period of time, the filter device needs to be removed for cleaning, or the filter device needs to be cleaned by spraying water on it with a cleaning device to ensure the normal operation of the dryer.

[0004] A Chinese invention patent with application number CN201210575631.7 discloses a lint filter device, comprising a first lint filter layer, a second lint filter layer and a three-layer lint filter layer, wherein the first lint filter layer and the second lint filter layer are mutually engaged and installed under the door body of the front air duct at the air outlet of the dryer drum, and the third lint filter layer is arranged in the internal air path of the dryer, and the lint is filtered and collected by the multiple filter layers, and the filter device is taken out for cleaning; although the above scheme realizes the filtering and collection of lint, there is still lint attached to the filter screen to generate resistance to the flow of dry air. If the user fails to clean the filter screen in time, the drying efficiency of the dryer will be greatly reduced.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a lint separation device for a clothes dryer in view of the problems in the above-mentioned prior art, wherein an inclined filter unit covering the cross-section of the air duct is arranged inside, and a cleaning unit is arranged on the filter unit, and the surface of the cleaning unit is cleaned by relative displacement between the cleaning unit and the filter unit, thereby ensuring that the filter unit is always in a clean state.

[0007] Another object of the present invention is to provide a dryer using the above-mentioned lint separation device. Since the filter unit in the dryer can clean the lint on the filter unit through relative displacement with the cleaning unit and collect the lint independently, it is ensured that the filter unit is always in a clean state, avoiding lint adhesion to the filter unit and affecting the filtering efficiency of the filter unit, thereby improving the drying efficiency of the dryer.

[0008] In order to achieve the above-mentioned object, the present invention provides a lint separation device for a clothes dryer in a first aspect, comprising a filter duct, wherein a filter assembly is provided in the filter duct, and the filter assembly comprises:

[0009] The filter unit has a mesh structure and is obliquely arranged in the filter air duct to cover the cross section of the filter air duct;

[0010] A cleaning unit is disposed on the surface of the mesh structure and is used to clean the wire scraps on the surface of the mesh structure through relative displacement with the filter unit;

[0011] The collecting unit is connected to the inside of the filter air duct and is used for collecting wire scraps.

[0012] In the above scheme, the cleaning unit can be relatively displaced with the filtering unit, thereby cleaning the mesh structure to ensure that the mesh structure is in a clean state; the cleaned lint is collected by the collecting unit after being detached from the mesh structure by the cleaning unit, and will not stay in the filter duct, thereby ensuring the cleanliness of the inside of the filter duct and improving the lint filtering effect.

[0013] Furthermore, the filtering unit remains stationary, and the cleaning unit is movably disposed on the surface of the mesh structure;

[0014] The collecting unit is arranged on the outer side of the filtering air duct along the moving direction of the cleaning unit.

[0015] In the above scheme, the cleaning unit can be movably arranged and the filtering unit remains stationary, thereby avoiding frequent movement of the filtering unit to affect the filtering effect, and the size of the cleaning unit is relatively small, and the movement is easier to achieve; the collecting unit is arranged on the outside of the filtering air duct along the moving direction of the cleaning unit, thereby achieving full separation of the lint filtering air duct and facilitating the collection of lint.

[0016] Furthermore, the cleaning unit is movably arranged perpendicular to the flow direction of the airflow;

[0017] A collecting port is formed on one side of the filter air duct in the moving direction of the cleaning unit, and the collecting unit is connected with the inside of the filter air duct through the collecting port;

[0018] One side edge of the collecting port is flush with the edge of the upper surface of the filtering unit and has the same length.

[0019] In the above scheme, the cleaning unit is movably arranged perpendicular to the direction of airflow flow, which reduces dead angles during the cleaning process and enables the surface of the mesh structure to be cleaned more fully; one side edge of the collecting port is flush with the edge of the upper surface of the filter unit and has the same length, so that the wire chips will not be blocked by the collecting port and can enter the collecting unit more smoothly, further avoiding the wire chips from remaining in the filter duct, thereby achieving full separation of the wire chips and the filter duct.

[0020] Furthermore, the thickness of the cleaning unit in the vertical direction gradually increases along the inclined direction of the filtering unit.

[0021] In the above scheme, the thickness of the cleaning unit in the vertical direction gradually increases along the inclination direction of the filtering unit, fully taking into account the situation that the wire chips fall and accumulate at a lower position during the wire chip cleaning process. By adjusting the thickness of the cleaning unit, the accumulated wire chips can be more fully blocked and all the wire chips can be pushed to the collection port, thereby achieving sufficient cleaning of the wire chips and avoiding the residual wire chips from affecting the cleaning effect.

[0022] Further, the filtering unit comprises a first end and a second end arranged opposite to each other in an inclined direction, the first end being located above the second end in a vertical direction, and the cleaning unit comprises:

[0023] A first surface is in contact with the surface of the filter unit, and two ends thereof extend to a first end and a second end respectively;

[0024] A second surface is connected to the first surface, extending outward from one end of the first surface to the second end, and is in contact with a side wall of the filtering air duct close to the second end;

[0025] The third surface connects one end of the first surface extending to the first end with the extended end of the second surface.

[0026] In the above scheme, the cleaning unit is respectively fitted with the surface of the filter unit and the air duct wall of the filter duct through the first surface and the second surface, so that the angle formed between the first surface and the second surface matches the inclination angle of the filter unit, which can better avoid the occurrence of cleaning dead corners and at the same time can push the cleaned wire scraps to the collection port more fully, further improving the cleaning effect.

[0027] Furthermore, the lint separation device also includes a collecting air duct arranged side by side with the filtering air duct, the filtering air duct and the collecting air duct have a common first air duct wall, the filtering air duct and the collecting air duct are connected through a connecting port arranged on the first air duct wall, the filtering unit is inclined along the air outlet direction from a side away from the collecting air duct to a direction close to the first air duct wall, and one end of the filtering unit close to the first air duct wall is close to the connecting port and flush with the lower edge of the connecting port;

[0028] The collecting unit is connected to the air outlet end of the collecting air duct, and the cleaning unit is movably arranged perpendicular to the air flow direction. The wire scraps cleaned by the cleaning unit enter the collecting unit through the connection and the collecting air duct.

[0029] In the above scheme, by setting up a collecting air duct side by side with the filtering air duct, the airflow entering the collecting air duct is used to drive the lint chips into the collecting unit more quickly, thereby further improving the efficiency of lint collection and preventing the lint chips from staying at the connection between the filtering air duct and the collecting air duct, or being blown back into the filtering air duct under the influence of the airflow in the filtering air duct.

[0030] Furthermore, the filtering unit is a mesh plate; and the cleaning unit is a brush or a flexible plate.

[0031] In the above scheme, a mesh plate is used as the filtering unit. The mesh plate has a certain rigidity, which avoids the deformation of the mesh plate during the cleaning process and causes the mesh plate to be unable to fully clean, thereby further improving the cleaning effect of the wire scraps. Due to the rigidity of the mesh plate, the optional range of cleaning units is increased, and a brush or a flexible plate can be selected. The deformation of the bristles on the brush or the deformation of the flexible plate can be used to increase the fit between the brush and the mesh plate, thereby achieving a more thorough cleaning of the filtering unit.

[0032] Furthermore, the cleaning units are disposed on both sides of the mesh structure, and the cleaning units located on both sides of the mesh structure move synchronously or independently of each other.

[0033] In the above solution, cleaning units are respectively arranged on both sides of the mesh structure, which can better solve the problem that the wire scraps are firmly entangled and cannot be fully cleaned by the cleaning unit on one side, and further improve the cleaning effect of the filter unit.

[0034] Furthermore, at least two filter units are arranged along the air outlet direction of the filter air duct, and a cleaning unit is arranged on each filter unit; by arranging multiple filter units, multi-stage filtration in the filter air duct is achieved, thereby being able to filter the wire scraps more thoroughly.

[0035] A second aspect of the present invention further provides a clothes dryer having a lint separation device as described in the above scheme, wherein the lint separation device is arranged in the front air duct of the clothes dryer to filter the airflow entering the front air duct.

[0036] When the lint filtering device has a filtering duct and a collecting duct arranged side by side, the air inlet ends of the filtering duct and the collecting duct face the air inlet end of the front air duct, and the air outlet end of the filtering duct is connected to the circulating air path inside the dryer, so that the filtering duct serves as a part of the circulating air path; the air outlet end of the collecting duct is connected to the collecting unit, and the collecting unit can be hidden inside the dryer and configured as a detachable structure, with an opening set from the bottom of the dryer or from the bottom of the front panel of the dryer to facilitate disassembly and cleaning by users.

[0037] The beneficial effects of the present invention are:

[0038] 1. By arranging a cleaning unit on the filter unit, the filter unit is cleaned by relative displacement between the cleaning unit and the filter unit, thereby avoiding the long-term accumulation of lint that affects the lint filtering effect and the drying efficiency of the dryer.

[0039] 2. The cleaning unit is movably arranged in a direction perpendicular to the air flow direction, and the collecting port is arranged in the moving direction of the cleaning unit, which shortens the time that the wire chips stay on the surface of the filter unit and can clean and collect the wire chips more quickly. In order to further improve the cleaning effect of the wire chips, the thickness of the cleaning unit is set to gradually increase along the inclination direction of the filter unit, which solves the problem of wire chips accumulating in large quantities at low places and being unable to be cleaned, and improves the cleaning effect.

[0040] 3. The wire scrap separation device also includes a collecting air duct arranged in parallel with the filtering air duct. The collecting air duct can more fully isolate the cleaned wire scraps from the filtering air duct, avoiding the cleaned wire scraps from being retained or returning to the filtering air duct, thereby further improving the wire scrap cleaning effect.

[0052] The present invention provides a lint separation device for a clothes dryer, such as Figures 1 to 7 As shown, it includes a filter duct 1, and a filter assembly 3 is provided in the filter duct 1. The filter assembly 3 includes:

[0053] The filter unit 31 has a mesh structure and is obliquely disposed in the filter air duct 1 to cover the cross section of the filter air duct 1;

[0054] The cleaning unit 32 is disposed on the surface of the mesh structure and is used to clean the wire scraps on the surface of the mesh structure through relative displacement with the filtering unit 31;

[0055] The collecting unit 33 is communicated with the interior of the filtering air duct 1 and is used for collecting lint.

[0056] In the above scheme, the cleaning unit 32 can be relatively displaced with the filtering unit 31, thereby cleaning the mesh structure to ensure that the mesh structure is in a clean state; the cleaned lint is detached from the mesh structure by the cleaning unit 32 and then collected by the collecting unit 33, and will not stay in the filter duct 1, thereby ensuring the cleanliness of the inside of the filter duct 1 and improving the lint filtering effect.

[0057] The present invention is further described in detail below with reference to specific embodiments.

[0058] Embodiment 1

[0059] As an embodiment of the present invention, this embodiment provides a lint separation device for a clothes dryer, in which the filter unit 31 remains stationary, and the cleaning unit 32 is movably arranged on the mesh structure surface of the cleaning unit 32 relative to the filter unit 31.

[0060] In this embodiment, the filter unit 31 is a mesh plate made of a rigid material, and a fixing unit for fixing the mesh plate is provided on the inner wall of the filter air duct 1, such as Figure 1 and Figure 3 As shown, the mesh plate is fixedly arranged in the filter duct 1 by a fixing unit. The fixing unit can be a boss protruding from the inner wall of the filter duct 1, or it can be a conventional fixing structure that cooperates with the filter unit 31 to fix the filter unit 31 by snapping, clamping, etc. The size of the mesh holes on the mesh plate is adjusted according to the wire chip filtering requirements to meet the wire chip filtering requirements.

[0061] Specifically, Figure 3 and Figure 5 As shown, the cleaning unit 32 is movably arranged perpendicular to the direction of airflow flow, that is, the moving direction of the cleaning unit 32 is perpendicular to the inclination direction of the filter unit 31, thereby reducing cleaning dead angles, improving cleaning efficiency, and ensuring the cleaning effect; a collecting port 5 connected to the outside is formed on the duct wall on one side of the filter duct 1 in the moving direction of the cleaning unit 32; the collecting unit 33 is arranged on the outer side of the duct wall on the side, and is connected to the inside of the filter duct 1 through the collecting port 5, so that the wire scraps cleaned by the cleaning unit 32 can approach the collecting port 5 as the cleaning unit 32 moves, and finally be discharged from the collecting port 5 to the outside of the filter duct 1, and be collected by the collecting unit 33, thereby avoiding the wire scraps from staying in the filter duct 1 after cleaning, and avoiding the wire scraps from being unable to be discharged in time and adhering to the surface of the filter unit 31 again, thereby further improving the cleaning effect.

[0062] It should be noted that the collecting unit 33 in the above solution can be arranged to be integrated with the filtering air duct 1 , or can be arranged to be detachable from the filtering air duct 1 .

[0063] Furthermore, since the filter unit 31 is tilted, the lint that falls off during the movement of the cleaning unit 32 will move along the tilted direction under the guidance of the filter unit 31 and gather on the lower side. When there are a lot of lint, the cleaning unit 32 may not be able to fully push all the lint to move, resulting in some lint being left on the surface of the filter unit 31. In order to avoid this problem, Figure 3 As shown, in this embodiment, the thickness of the cleaning unit 32 in the vertical direction gradually increases along the inclination direction of the filter unit 31, thereby preventing wire scraps from being missed during the movement, thereby ensuring sufficient cleaning of the filter unit 31.

[0064] Specifically, the filter unit 31 includes a first end and a second end that are arranged opposite to each other along an inclined direction, the first end is located above the second end in the vertical direction, that is, the entire filter unit 31 is inclined from the position of the first end to the position of the second end along the air outlet direction and covers the cross section of the filter air duct 1, the cleaning unit 32 has a first surface 321 that is in contact with the surface of the filter unit 31, and the two ends of the first surface 321 extend to the first end and the second end respectively, that is, the inclination angle of the first surface 321 is consistent with that of the filter unit 31, and the first surface 321 is inclined along the filter unit 31. The length in the oblique direction is the same as that of the filter unit 31, ensuring that during the cleaning process, the cleaning unit 32 can fully cover the surface of the filter unit 31; it also has a second surface 322 connected to the first surface 321, and the second surface 322 is extended outward from one end extending from the first surface 321 to the second end, and is fitted with the side wall surface of the filter duct 1 close to the second end; the other end of the second surface 322 is connected to one end extending from the first surface 321 to the first end through the third surface 323, that is, the shape of the cross-section of the cleaning unit 32 perpendicular to the moving direction is generally triangular.

[0065] It should be noted here that in order to avoid missing lint, the first surface 321 and the second surface 322 are both set to be planes, so that they can better fit with the surface of the filter unit 31 and the air duct wall; and the third surface 323 can be set to a plane, curved surface or folded surface according to actual usage requirements.

[0066] Furthermore, the cleaning unit 32 in the above scheme has a common characteristic, that is, at least the side in contact with the filter unit 31 has a certain flexibility, and can produce a certain deformation while in contact with the filter unit 31 to improve the cleaning effect; in this embodiment, the cleaning unit 32 is a brush, and the side of the brush with bristles is the first surface 321; or the cleaning unit 32 can also be a flexible plate with a certain flexibility.

[0067] Embodiment 2

[0068] As another embodiment of the present invention, this embodiment provides a lint separation device for a clothes dryer. The difference from the embodiment is that the lint separation device has two air ducts arranged side by side.

[0069] In this embodiment, if Figure 2 and Figure 4As shown, the lint separation device includes a filtering duct 1 and a collecting duct 2 arranged side by side, the air inlet and air outlet of the filtering duct 1 and the collecting duct 2 are oriented in the same direction and are separated by a common first duct wall 4, the filtering unit 31 is arranged in the filtering duct 1, and is inclined along the air outlet direction toward the first duct wall 4, a connecting port connecting the filtering duct 1 and the collecting duct 2 is provided on the first duct wall 4, the lower edge of the connecting port is flush with one end of the filtering unit 31 close to the first duct wall 4, the lint blocked by the filtering unit 31 can move along the inclined direction of the filtering unit 31 under the influence of airflow and gravity and enter the collecting duct 2 through the collecting port 5, the air outlet end of the collecting duct 2 is connected to the collecting unit 33, and the lint can be discharged to the outside of the duct in time, so as to realize the full separation and independent collection of the lint. It should be noted that the connecting port in this embodiment is the collecting port 5.

[0070] Furthermore, the cleaning unit 32 is movably arranged on the surface of the filter unit 31 perpendicular to the direction of airflow flow, and the wire scraps attached to the filter unit 31 removed by the cleaning unit 32 can move along the inclined direction of the filter unit 31 and finally enter the collecting air duct 2 through the collecting port 5.

[0071] In order to further improve the cleaning effect, cleaning units 32 may be respectively provided on both sides of the filter unit 31 . The two cleaning units 32 are independently and movably provided to each other, thereby enabling a more complete and thorough cleaning of the filter unit 31 .

[0072] Embodiment 3

[0073] As another embodiment of the present invention, this embodiment differs from the second embodiment in that the cleaning unit 32 remains fixed, and the filter unit 31 is movably disposed relative to the cleaning unit 32 .

[0074] In this embodiment, if Figure 6 As shown, the filter unit 31 includes a filter part 311 with a mesh structure, and the filter part 311 covers the cross-section of the filter air duct 1 to block the wire scraps; it also includes a driving part 312, and the driving part 312 is connected to the filter part 311, and is used to drive the filter part 311 to cause relative displacement between the filter part 311.

[0075] Specifically, the driving part 312 is two scrolls which are parallel to each other and spaced apart. The two ends of the filter part 311 are respectively wound around the two scrolls, and the rotation of the two scrolls drives the filter part 311 and the cleaning unit 32 to be relatively displaced. In order to ensure that the filter part 311 can fully cover the cross-section of the filter duct 1, the two scrolls are respectively arranged near the opposite sides of the filter duct 1. For this purpose, the filter part 311 is arranged as a filter net or a flexible mesh plate which can be deformed freely and is flexible.

[0076] In order to ensure the smooth shedding of lint, the two reels are at an angle to the air outlet direction of the filtering air duct 1, and are inclined from the end away from the collecting air duct 2 toward the first air duct wall 4 along the air flow direction, so that the upper surface of the filter part 311 close to the end of the first air duct wall 4 is flush with the lower edge of the connecting port provided on the first air duct wall 4, and the lint that is blocked and shed by the cleaning unit 32 can directly enter the collecting air duct 2 through the connecting port, and then be discharged into the collecting unit 33 from the air outlet end of the collecting air duct 2, thereby achieving full separation of the lint and the filtering unit 31.

[0077] When cleaning the wire scraps attached to the filter part 311, the two reels rotate independently in the same direction, which can reduce the tension on the filter part 311 during the cleaning process, avoid damage to the filter part 311 due to excessive tension, and increase the service life of the wire scrap separation device; or one of the reels actively rotates, and the other reel is driven to passively rotate through the filter part 311. In the above scheme, the two reels are connected by transmission through the filter part 311, so that the filter part 311 is always in a taut state under the influence of tension, which can better realize the cleaning of surface wire scraps.

[0078] Furthermore, in order to simplify the cleaning process, the cleaning unit 32 is arranged close to the reel, so that during the cleaning process, the two reels only need to continue to rotate in the direction of the cleaning unit 32 to fully clean the wire scraps attached to the surface of the filter part 311; or, considering the length of the filter part 311, the cleaning unit 32 can also be arranged between the two reels. Although the two reels need to rotate in two different directions to fully clean the wire scraps, the length of the filter part 311 is shortened, thereby reducing the production cost.

[0079] Furthermore, two cleaning units 32 are provided on the filter unit 31 . The two cleaning units 32 are respectively provided on both sides of the filter portion 311 , so as to better clean the wire scraps on the filter portion 311 .

[0080] Embodiment 4

[0081] As another embodiment of the present invention, this embodiment differs from the third embodiment in that the structure of the filter unit 31 is different.

[0082] In this embodiment, if Figure 7 As shown, the filter unit 31 includes a filter portion 311 and two rotating shafts. The two rotating shafts are arranged parallel to each other and spaced apart. The two ends of the filter unit 31 are connected end to end to form an annular track, which is mounted on two reels. Even if the two reels always rotate in the same direction, the wire scrap filtering effect will not be affected due to the insufficient length of the filter portion 311.

[0083] Furthermore, when two cleaning units 32 are provided on the filter unit 31, the two cleaning units 32 are respectively provided close to the two reels, that is, no matter in which direction the two reels rotate, the wire scraps will not pass over the cleaning unit 32, thereby reducing the problem of the wire scraps falling off from the bottom of the filter unit 31 as the filter portion 311 moves.

[0084] In order to further improve the cleaning effect of wire scraps, cleaning units 32 are provided on both sides of the filter part 311, that is, cleaning units 32 are provided on the inner circumference and outer circumference of the annular track; preferably, the cleaning units 32 on the inner circumference and the outer circumference are relative to each other, which can better realize the cleaning of wire scraps.

[0085] Embodiment 5

[0086] As another embodiment of the present invention, the following improvements are further made on the basis of the first embodiment.

[0087] In this embodiment, at least two filter units 31 are arranged at intervals along the air outlet direction of the lint separation device, and a cleaning unit 32 is provided on each filter unit 31 .

[0088] Furthermore, the inclination direction of the plurality of filter units 31 spaced apart along the air outlet direction is the same, and each filter unit 31 has a corresponding collection port 5 .

[0089] It should be noted that the solution recorded in this embodiment is also applicable to the embodiments described in Examples 2 to 4, and the technical solution obtained by combining this embodiment with Examples 2 to 4 respectively also falls within the protection scope of the present invention.

[0093] In this embodiment, the dryer has a circulating air duct, the air inlet of the circulating air duct is connected with the interior of the dryer drum from the bottom of the front window pad, and the air outlet of the circulating air duct is connected with the interior of the drum from the rear or top of the drum to form a circulating air path; the lint separation device described in Example 1 is arranged in the front air duct arranged in the vertical direction at the bottom of the window pad.

[0094] Furthermore, the dryer has a control unit, and the filter unit 31 of the lint separation device has a wind resistance detection unit for detecting wind resistance, and the wind resistance detection unit is communicatively connected to the control unit of the dryer; and the lint separation device is provided with a driving unit for driving the cleaning unit 32 to move, and the driving unit is communicatively connected to the control unit. The wind resistance detection unit sends the detected wind resistance information to the control unit, and when the control unit determines that the amount of lint attachment is large based on the wind resistance information, the control unit controls the driving unit to work and cleans the filter unit 31, thereby realizing automatic cleaning of lint. The user only needs to clean the collection unit 33 regularly, and there is no need to remove the lint separation device, thereby improving the user experience.

[0095] The clothes dryer in this embodiment can also adopt the lint separation device as described in Examples 2 to 5, and the technical solutions obtained by combining this embodiment with Examples 2 to 5 respectively also fall within the protection scope of the present invention; it should be additionally explained that the clothes dryer obtained by combining Example 3 and Example 4 with this embodiment also has a driving unit, and the difference from Example 1 is that the driving unit in Example 3 and the embodiments drives the reel to rotate.

[0096] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
