Description

Technical Field

[0001] The present invention belongs to the field of clothes dryers, and in particular relates to a clothes dryer and a lint collecting 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 of the dryer.

[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 sprayed with water for cleaning by a cleaning device to ensure the normal operation of the dryer.

[0004] Chinese invention patent 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. 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. The third lint filter layer is arranged in the internal air path of the dryer. Lint is filtered and collected by multiple filter layers, and the filter device is taken out for cleaning. Although the above scheme achieves the filtering and collection of lint, there is still lint attached to the filter screen, which creates 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] Chinese utility model patent application number CN201920462931.1 discloses a cleaning system for a lint filter, comprising a spray flushing device for flushing lint on the lint filter, and a collecting box connected to the lower part of the lint filter for collecting lint flushed from the lint filter. When the lint filter is disassembled for cleaning, the collecting box can be removed and cleaned together; although the above scheme realizes the cleaning of the lint filter and collects the lint flushed from the lint filter into the collecting box, during a single operation, as the lint adheres, the flow rate of the dry air in the dryer will still change, and using the flushing device to clean the lint filter also causes a waste of water resources.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The purpose of the present invention is to provide a lint collection device to address the problems in the above-mentioned prior art, including an air duct and a collection box connected to the air duct. The lint separated from the air flow is collected separately by the collection box, and the user can clean the lint more easily.

[0008] Another object of the present invention is to provide a clothes dryer with a lint collecting device, which collects lint separated from the drying air flow to prevent the lint from accumulating in the air path and reducing the drying effect.

[0009] In order to achieve the above object, the present invention provides a lint collecting device for a clothes dryer, comprising:

[0010] The first air duct is provided with a filter unit inside for filtering lint;

[0011] The second air duct is arranged side by side with the first air duct and is used to guide and discharge the lint filtered by the filter unit.

[0012] In the above solution, the lint is collected and discharged through the second air duct, thereby preventing the lint from accumulating in the air duct and improving the lint separation effect.

[0013] Furthermore, the lint collecting device further comprises:

[0014] The collecting box is installed at the air outlet end of the second air duct and is used to collect the lint discharged by the second air duct.

[0016] In the above solution, the lint discharged from the second air duct is collected by the collection box, thereby preventing the lint from being directly discharged and causing pollution to the environment.

[0017] The lint collection device further includes a connecting portion connected to the first air duct and the second air duct, and a supporting portion for supporting the collection box is formed by being recessed inward from one side of the connecting portion, and the collection box is detachably installed in the supporting portion.

[0018] The collection box is detachably connected to the connection portion, which makes it easier to clean the wire scraps in the collection box and avoids repeated disassembly and assembly of the wire scrap collection device.

[0019] The supporting portion is provided with a second opening opposite to the first opening. When the collection box is installed in place, the first opening is aligned with the second opening, and the collection box is connected to the air outlet end of the second air duct through the first opening and the second opening.

[0020] Furthermore, the other side of the connecting portion opposite to the supporting portion is recessed inward to form an air guide portion for guiding the airflow discharged from the first air duct, and a third opening is provided on the air guide portion, which is connected to the air outlet of the first air duct through the third opening.

[0021] Furthermore, a filter is provided on the side of the collection box facing the interior of the supporting portion, the air guide portion and the connecting portion are connected to penetrate the connecting portion, and a first retaining rib is provided in the connecting portion for limiting the installation position of the collection box.

[0022] Furthermore, the first retaining rib extends outward from the connecting portion to form a second retaining rib, and the second retaining rib separates the second opening from the third opening.

[0023] In the above scheme, after the lint enters the collection box driven by the airflow, the airflow is discharged from the filter and mixed with the airflow discharged from the first air duct, thereby avoiding the formation of vortexes in the collection box that affect the collection effect; the first baffle rib limits the installation of the collection box inside the connecting part, thereby improving the accuracy of the installation of the collection box.

[0024] Furthermore, when the collection box is installed in place, the first retaining rib is in contact with the side of the collection box facing the interior of the supporting portion, thereby improving the installation stability of the collection box.

[0025] Furthermore, the connecting portion further includes:

[0026] The second retaining rib is extended outward from the outer side of the connecting portion to separate the second opening from the third opening.

[0027] Furthermore, the second retaining rib protrudes slightly from the connecting portion, which improves the strength of the connecting portion and improves the airtightness when cooperating with the wire scrap separation device, so that the wire scraps can all enter the collection box under the obstruction of the second retaining rib.

[0028] Furthermore, the side of the collection box facing the interior of the connecting portion is a non-planar structure, which can expand the volume of the collection box as much as possible without expanding the area of ​​the first opening and without affecting the flow of air.

[0029] Preferably, the first air duct and the second air duct are an integrated structure, separated by a partition, and have the same air outlet, and the air outlet ends of the first air duct and the second air duct are respectively located on both sides of the same air outlet separated by the partition.

[0031] Furthermore, the connecting portion further includes:

[0032] A third retaining rib is formed by extending outward from an end portion of the connecting portion on a side where the collecting box enters;

[0033] When the lint collecting device is installed in place, the third retaining rib contacts the front side of the clothes dryer.

[0034] In the above solution, the third retaining rib enables the connecting portion to be installed in place along the horizontal direction.

[0035] Furthermore, the clothes dryer further includes:

[0036] The matching portion is provided between the connecting portion and the air outlet ends of the first air duct and the second air duct, and is used to make the first air duct, the second air duct and the connecting portion closely matched.

[0037] Furthermore, the first opening and the second opening extend toward one side close to the first air duct and the second air duct, and an end of the matching portion close to the dryer air outlet is provided with a guiding structure inclined toward the lower end of the extending side of the second opening.

[0038] The beneficial effects of the present invention are as follows: the first air duct and the second air duct are used to filter and guide the wire scraps, so that the wire scraps are prevented from remaining in the air duct and affecting the filtering effect; the wire scraps discharged from the second air duct are collected by the collection box, so that the wire scraps are prevented from being directly discharged and polluting the environment; the connecting part includes a supporting part and an air guide part that are interconnected, and the collection box is detachably installed in the supporting part, and is connected to the second air duct through the supporting part, so that the collection box can be detachably connected, and the user can disassemble and clean the collection box more easily; the air guide part is provided with a third opening, and the air guide part is connected to the first air duct through the third opening, so that The filtered wind is guided; a filter is provided on the side of the collection box facing the inside of the supporting part, and the airflow that sends the lint into the collection box is discharged from the filter and enters the air guide part to continue circulating, so as to avoid the airflow forming vortexes in the collection box and affecting the collection effect; a retaining rib is provided in the connecting part to limit the installation position of the collection box, so that the collection box is easier to install in place, and it is avoided that the collection box and the air outlet of the second air duct are not aligned when the installation is not in place, which affects the collection and filtering effects; a matching part is also provided between the first air duct, the second air duct and the connecting part, so that the first air duct, the second air duct and the connecting part are tightly matched.

[0047] Example 1

[0048] As an embodiment of the present invention, this embodiment provides a wire scrap collecting device, comprising:

[0049] The first air duct is provided with a filter unit inside for filtering lint;

[0050] The second air duct is arranged side by side with the first air duct and is used to guide and discharge the lint filtered by the filter unit;

[0051] The first air duct and the second air duct are an integrated structure, separated by a partition, and have the same air outlet. The air outlet ends of the first air duct and the second air duct are respectively located on both sides of the same air outlet separated by the partition.

[0052] In this embodiment, if Figure 1As shown, a collecting box 1 for collecting lint is further provided at the air outlet end of the second air duct. A first opening 11 is provided on the collecting box 1 and is communicated with the air outlet end of the second air duct through the first opening 11 .

[0053] Further, such as Figure 2 and Figure 3 As shown, it also includes a connecting part 2, one side of the connecting part 2 is recessed inward to form a supporting part for supporting the collection box 1, and the collection box 1 is detachably installed in the supporting part. A second opening 21 opposite to the first opening 11 is provided on the connecting part 2. When the collection box 1 is installed in place, the first opening 11 is aligned with the second opening 21, and the collection box 1 is connected to the air outlet end of the second air duct through the first opening 11 and the second opening 21.

[0054] Furthermore, a first retaining rib 23 is provided in the connecting portion 2 for limiting the installation position of the collecting box 1 .

[0055] The above scheme supports the collection box 1 through the connecting part 2, and the user can disassemble the collection box 1 for cleaning more conveniently to avoid the accumulation of lint affecting the collection effect. At the same time, the first retaining rib 23 positions the connection between the collection box 1 and the air outlet end of the second air duct, thereby improving the accuracy of the installation of the collection box 1.

[0056] Furthermore, the other side of the connecting portion 2 opposite to the supporting portion is recessed inward to form an air guide portion for guiding the airflow discharged from the first air duct. The air guide portion is provided with a third opening 22, and the air guide portion is connected to the air outlet end of the first air duct through the third opening 22.

[0057] The above solution achieves the goal of guiding the lint and the filtered air separately, thus preventing the lint from circulating with the clean air and affecting the drying effect.

[0058] Furthermore, a filter 12 is provided on the side of the collection box 1 facing the interior of the supporting part. The wind that sends the lint into the collection box 1 enters the air guide part through the filter 12 and mixes with the clean air for circulation, avoiding the formation of vortexes inside the collection box 1 that affect the collection effect.

[0059] Furthermore, the first retaining rib 23 is a ring rib having the same shape as the edge of the collecting box 1 facing the inner side of the supporting portion. When the collecting box 1 is installed in place, the first retaining rib 23 fits tightly against the collecting box 1 .

[0060] Furthermore, the side of the collection box 1 facing the interior of the connecting portion 2 is a non-planar structure, which can maximize the volume of the collection box 1 without increasing the area of ​​the first opening 11 and affecting the flow of air.

[0061] Furthermore, a second retaining rib 24 is formed extending outward from the connecting portion 2 opposite to the first retaining rib 23 , and the second retaining rib 24 separates the second opening 21 from the third opening 22 .

[0062] The second retaining rib 24 slightly protrudes from the connecting portion 2 , which improves the strength of the connecting portion 2 and the airtightness when cooperating with the wire scrap separation device, so that the wire scraps can all enter the collection box 1 under the obstruction of the second retaining rib 24 .

[0063] Example 2

[0064] As another embodiment of the present invention, this embodiment provides a wire scrap collection device having the same structure as that of the first embodiment, except that the area of ​​the first opening is smaller than the area of ​​the second opening. When the collection box is installed in place, the first opening is located on one side of the second opening close to the end of the supporting portion.

[0065] In the above scheme, the area of ​​the first opening is smaller than that of the second opening, and some clean air in the first air duct can also enter the collection box from the second opening, so that the lint can be guided into the collection box more smoothly. The airflow entering the collection box passes through the filter net and enters the air guide part for circulation, which does not affect the normal operation of the collection box.

[0066] Example 3

[0067] As another embodiment of the present invention, this embodiment provides a lint collection device having the same structure as that of the first embodiment, except that a fixing member for fixing the air duct is provided on the connecting portion, and the first air duct and the second air duct are detachably connected to the connecting portion through the fixing member.

[0068] The above solution achieves a tight connection between the air duct and the connecting part, avoids leakage of lint, and improves the airtightness of the lint collecting device.

[0069] Example 4

[0070] As another embodiment of the present invention, this embodiment provides a lint collection device having the same structure as that of the third embodiment, with the difference that the supporting portion is a closed cavity, connected to the air outlet end of the second air duct through a second opening, and the cavity and the air guide portion are separated by a filter.

[0071] When the user needs to clean the lint, the connection part is removed for cleaning. The supporting part and the air guide part can be cleaned at the same time, and the small amount of lint that enters the branch part is also cleaned to avoid the lint affecting the collection effect. At the same time, the filter can be replaced more conveniently to avoid the filter damage causing the lint collection device to fail, thereby improving the working stability of the lint collection device.

[0072] The present invention further provides a clothes dryer having the above-mentioned lint collecting device, specifically comprising:

[0073] Example 5

The supporting part is arranged at the front end of the dryer and is staggered with the drum.

[0076] Furthermore, the connecting portion 2 further includes:

[0077] A third retaining rib 25 extends outward from an end portion of the connecting portion 2 on a side where the collecting box 1 enters;

[0078] When the lint collecting device is installed in place, the third retaining rib 25 contacts the front side of the clothes dryer.

[0079] Furthermore, the first opening 11 and the second opening 21 extend to one side of the collecting box 1 close to the air outlet of the dryer, so that the lint collecting device can more smoothly collect lint from the lint separation device that is not vertically aligned with the lint collecting device.

[0080] Further, such as Figure 4 As shown, the clothes dryer also includes,

[0081] The matching portion 3 is provided between the connecting portion 2 and the air outlet ends of the first air duct and the second air duct, and is used to make the first air duct, the second air duct and the connecting portion 2 closely match.

[0082] Furthermore, the connecting portion 2 further includes:

[0083] A fourth retaining rib 26 is parallel to the third retaining rib 25 and extends outward from the outer side of the connecting portion 2;

[0084] The matching portion 3 is located between the third blocking rib 25 and the fourth blocking rib 26 and has a through hole 32 for air and wire scraps to pass through.

[0085] Furthermore, the first opening 11 and the second opening 21 extend toward one side close to the first air duct and the second air duct, and the end of the matching portion 3 close to the dryer air outlet is provided with a guide structure 31 inclined toward the lower end of the extending side of the second opening 21.

[0086] In the above scheme, the through hole 32 on the connecting part 2 will not affect the smooth entry of the lint into the collection box 1. The guiding structure 31 is arranged at one end of the connecting part 2 close to the air outlet of the dryer, and is inclined at the lower end extending toward the second opening 21, thereby further improving the airtightness of the connection between the connecting part 2 and the air duct.
