Description

Technical Field

[0001] This invention belongs to the field of clothes dryers, and specifically relates to a clothes dryer and its lint collection device. Background Technology

[0002] During the operation of a clothes dryer, lint and dander from clothing inevitably flow with the drying air and are blocked by the lint filter, remaining on the filter. As the dryer is used, the lint and dander accumulate on the lint filter, obstructing the flow of drying air, which reduces the drying efficiency and worsens the drying effect.

[0003] To address this issue, existing technologies typically employ a detachable lint filter. After a period of use, the filter needs to be removed for cleaning, or it can be cleaned by spraying water onto the filter using a cleaning device, thus ensuring the dryer's normal operation.

[0004] Chinese invention patent application number CN201210575631.7 discloses a lint filter device, including a first lint filter layer, a second lint filter layer, and a third lint filter layer. The first and second lint filter layers are interlocked and installed below the door of the front air duct at the air outlet of the dryer drum. The third lint filter layer is located in the internal air duct of the dryer. The lint is filtered and collected through multiple filter layers, and the filter device can be removed for cleaning. Although the above solution achieves the filtration and collection of lint, lint still adheres to the filter screen, creating resistance to the flow of dry air. If the user does not clean the filter screen in time, the drying efficiency of the dryer will drop significantly. If the user frequently disassembles and cleans the filter screen, the sealing performance of the filter screen in the air duct may decrease, resulting in a reduction in the filtration effect.

[0005] Chinese utility model patent application number CN201922122573.2 discloses a lint filter and a clothes dryer, including a first filter frame and a second filter frame, which are fastened together. An air inlet plate is provided at the top of either the first or second filter frame, and first connecting parts for connecting to the clothes dryer are provided at both ends of the air inlet plate. The first connecting parts are provided with sealing components for sealing the air inlet plate, thus achieving a seal at the connection between the lint filter and the clothes dryer. While the above solution discloses a method to improve the sealing performance of the lint filter by setting a sealing component, the lint filter cannot be easily removed from the sensor or its interior for cleaning. With prolonged use, lint may adhere to the filter, reducing the circulation speed of the circulating air. Furthermore, the above solution only addresses the gap between the lint filter and the clothes dryer; lint may still remain in the gaps inside the lint filter, affecting the lint filtration efficiency.

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

[0007] The purpose of this invention is to provide a lint collection device to address the problems in the prior art, including a separation component for separating lint and a collection component for collecting lint. By providing a sealing component on the collection component, the sealing performance between the separation component and the collection component is improved, preventing lint from leaking out from the gaps.

[0008] Another objective of this invention is to provide a dryer with a lint collection device. By placing the lint collection device inside the dryer, lint can be collected while preventing leakage from the gaps between the various components. This allows users to clean up the lint more easily and improves the user experience.

[0009] To achieve the above objectives, a first aspect of the present invention provides a wire debris collection device, comprising,

[0010] The separation component has a first air duct and a second air duct arranged side by side and connected to each other. The first air duct is equipped with a filter unit, which is used to filter lint and guide the lint to the second air duct for discharge.

[0011] A collecting component, connected to the separating component, is used to collect thread debris;

[0012] A sealing component, disposed on the collecting component, is used to improve the sealing performance of the lint collecting device.

[0013] In the above scheme, the sealing component is a felt, rubber strip or sealing gasket with deformability.

[0014] Furthermore, the collection component includes,

[0015] The collecting section is recessed inward from one side of the collecting component;

[0016] A collection box, detachably installed inside the collection section, is used to collect thread debris;

[0017] The collection box is provided with a lint inlet, and the collection part is provided with a first opening. When the collection box is installed in place, the lint inlet and the first opening are aligned.

[0018] Furthermore, the collection box includes,

[0019] The first positioning rib is fixed to the outside of the collection box and is used to position the collection box in place.

[0020] When the collection box is installed in place, the first positioning rib is in close contact with the end of the collection part.

[0021] Furthermore, the sealing assembly includes,

[0022] The first sealing part is provided on the positioning rib on the side facing the collecting part;

[0023] When the collection box is installed in place, the first sealing part is tightly attached to the end of the collection part.

[0024] In the above solution, since the collection box is detachably installed inside the collection section, there is a gap between the collection box and the collection section. During the collection of lint, the lint may leak from the gap, increasing the difficulty of cleaning for the user. By setting a first sealing part, some of the leaked lint is kept in the collection section, preventing the lint from leaking directly from the gap to the outside of the dryer and affecting the external environment, thus improving the user experience.

[0025] Furthermore, the collection component also includes,

[0026] The air guide section is recessed inward from the other side of the collection assembly, opposite to the collection section;

[0027] The air guide section is provided with a second opening, and the air guide section is connected to the first air duct through the second opening.

[0028] Furthermore, the air guide section and the collection section are connected, connecting the collection assembly, which further includes...

[0029] A limiting rib is provided inside the collection assembly to limit the installation of the collection box into place.

[0030] Furthermore, a filter screen is provided on the side of the collection box facing the inside of the collection section, and the limiting rib is a ring rib set inside the collection assembly.

[0031] The sealing assembly also includes,

[0032] The second sealing part is provided on the limiting rib.

[0033] In the above solution, the limiting rib further limits the installation of the collection box, while the second sealing part on the limiting rib seals the filter screen on the collection box, preventing lint from accumulating at the filter screen and affecting the normal discharge of circulating air.

[0034] Furthermore, the collection component also includes,

[0035] The second positioning rib is parallel to the limiting rib and extends outward from the edges of the two opposite sides of the second opening;

[0036] When the separation component and the collection component are in place, the air outlet of the first air duct is tightly fitted with the second positioning rib.

[0037] Furthermore, the sealing assembly also includes,

[0038] The third sealing part is provided on the second positioning rib;

[0039] When the first air duct and the collection component are in place, the third sealing part is located between the second positioning rib and the air outlet of the first air duct.

[0040] In the above solution, the third sealing part achieves full separation of lint and circulating air, preventing lint leaking into the gap from entering the air guide and circulating again, thus affecting the lint separation effect.

[0041] A second aspect of the present invention provides a clothes dryer having the lint collection device described in the above-mentioned solution, wherein the separation component of the lint collection device is disposed in the front air duct of the clothes dryer, and the clothes dryer includes...

[0042] An installation section is located on the front side of the dryer and is used to install the collection assembly;

[0043] The door body is located at the end of the mounting portion.

[0044] In the above solution, when the collection component is installed inside the installation part, the door closes to block the collection box and prevent it from falling out. At the same time, the door squeezes the collection box to make the collection box and the collection part fit tightly together, which improves the sealing effect of the sealing component.

[0045] Furthermore, the collection component also includes,

[0046] The third positioning rib is formed by folding outward from the end of the collecting part and is used to position the collecting component in place.

[0047] Furthermore, the sealing assembly also includes,

[0048] The fourth sealing part is located on the side of the third positioning rib facing the dryer;

[0049] When the collection component is installed in place, the fourth sealing part is in close contact with the front panel of the dryer.

[0050] In the above solution, the fourth sealing part achieves a seal between the collection component and the front panel of the dryer, preventing lint from leaking out of the gaps and affecting the usage environment.

[0051] The beneficial effects of this invention are as follows:

[0052] The collection component collects the lint separated by the separation component. The collection component includes a collection section and a collection box detachably installed within the collection section. Users can clean the lint by disassembling and cleaning the collection box, preventing lint residue from remaining in the separation and collection components and affecting the lint separation and collection efficiency. A first sealing part is provided on the first positioning rib to prevent lint from leaking directly from the gap to the outside of the dryer and affecting the external environment, thus improving the user experience. When the collection box is installed in place, the side with the filter screen is in contact with the limiting rib. At this time, lint entering through the gap between the collection box and the collection section will not affect the filter screen due to the second sealing part. The filter screen acts as a barrier, allowing the circulating air that carries lint into the collection box to pass smoothly through the filter screen and enter the circulating air duct for circulation. The third sealing part, located on the second positioning rib, ensures a tight fit between the separation component and the collection component, preventing lint from entering the air guide section through gaps and affecting the lint separation effect. The fourth sealing part prevents lint from leaking out of the gap between the collection component and the mounting part into the outside of the dryer, affecting the dryer's operating environment. The door on the mounting part improves the dryer's aesthetics while preventing the collection box from falling off. It also compresses the collection box, making the seal between the first and second sealing parts between the collection part and the collection box even tighter. Attached Figure Description

Therefore, they should not be construed as limiting this invention.

[0061] Example 1

[0062] As an embodiment of the present invention, this embodiment provides a wire debris collection device, such as... Figure 1 As shown, it includes a separation component 3, which has a first air duct and a second air duct arranged side by side and connected to each other. The first air duct is equipped with a filter unit, which is used to filter lint and guide the lint to the second air duct for discharge.

[0063] Collection component 2, connected to the separation component 3, is used to collect thread debris;

[0064] A sealing component is provided on the collecting component 2 to improve the sealing performance of the lint collecting device.

[0065] In this embodiment, the collection component 2 includes,

[0066] The collecting part 21 is recessed inward from one side of the collecting component 2;

[0067] Collection box 1 is detachably installed inside the collection part 21 for collecting thread scraps;

[0068] The air guide section 22 is recessed inward from the other side of the collection assembly 2, opposite to the collection section 21;

[0069] The air guide section 22 is provided with a second opening, and the air guide section 22 is connected to the first air duct through the second opening; the collection box 1 is provided with a lint inlet 11, and the collection section 21 is provided with a first opening. When the collection box 1 is installed in place, the lint inlet 11 and the first opening are aligned.

[0070] In the above solution, after the lint is separated from the circulating air by the separation component 3, it enters the collection component 2 through the second air duct and is finally collected in the collection box 1. Users can clean the lint by removing the collection box 1 for cleaning, which improves the user experience.

[0071] Furthermore, such as Figure 2 As shown, the outer side of the collection box 1 is provided with a first positioning rib 13. When the collection box 1 is installed in place, the first positioning rib 13 contacts the end of the collection part 21 to achieve the positioning of the collection box 1 in place.

[0072] Furthermore, the above solution also includes a sealing component, which is a deformable felt. The sealing component includes...

[0073] The first sealing part 131 is provided on the side of the first positioning rib 13 facing the collecting part 21;

[0074] When the collection box 1 is installed in place, the first sealing part 131 is tightly attached to the end of the collection part 21.

[0075] The above solution improves the sealing performance between the collection box 1 and the collection part 21 by setting the first sealing part 131, preventing lint from leaking directly from the gap between the collection box 1 and the collection part 21 to the outside of the dryer and affecting the external environment, thus improving the user experience.

[0076] Furthermore, such as Figure 3 As shown, the collection part 21 and the air guide part 22 are connected and pass through the collection component 2. The collection component 2 is also provided with a limiting rib 23 for limiting the installation of the collection box 1. The limiting rib 23 is used to position the collection box 1 in place.

[0077] Furthermore, such as Figure 4 As shown, the limiting rib 23 is a ring rib provided in the collection assembly 2. The collection box 1 is provided with a filter screen 12 on the side facing the inside of the collection part 21. A second sealing part 231 is also provided on the limiting rib 23.

[0078] The above solution involves setting the second sealing part 231 on the limiting rib 23. When the collection box 1 is installed in place, the second sealing part 231 fits tightly with the collection box 1. At this time, the wire debris in the gap between the collection box 1 and the collection part 21 is blocked by the second sealing part 231 and will not block the filter screen 12. The circulating air that sends the wire debris into the collection box 1 can pass through the filter screen 12 smoothly and enter the air guide part 22. It enters the circulating air duct along with the filtered air. If the wire debris blocks the filter screen 12, causing the circulating air that sends the wire debris into the collection box 1 to not pass through the filter screen 12 smoothly, eddies may be generated in the collection box 1, causing the wire debris to not enter the collection box 1 smoothly. This may cause the wire debris to enter the circulating air duct with the circulating air, thereby reducing the wire debris separation effect.

[0079] Furthermore, a second positioning rib 24 is provided at the edge of the second opening. The second positioning rib 24 is parallel to the limiting rib 23 and extends outward from the edges of the opposite sides of the second opening. When the separation component 3 and the collection component 2 are in place, the air outlet of the first air duct is close to the second positioning rib 24.

[0080] Furthermore, a third sealing part 241 is provided on the second positioning rib 24. When the separation component 3 and the collection component 2 are in place, the third sealing part 241 fits tightly with the air outlet of the first air duct, preventing wire debris from entering the air guide part 22 from the gap between the first air duct and the collection component 2, thus giving the wire debris collection device better sealing performance and improving the wire debris separation effect.

[0081] Example 2

[0082] As another embodiment of the present invention, this embodiment provides a lint collection device with a structure similar to that of Embodiment 1. The difference is that, in this embodiment, the first sealing part is disposed at the end of the collection part and protrudes into the collection part.

[0083] In the above scheme, the first sealing part protrudes into the collection part. Since the first sealing part is a felt with deformation capability, when the collection box is installed into the collection part, it will squeeze the first sealing part to deform it. As a result, there is a relatively large friction between the first sealing part and the collection box, which improves the stability of the collection box in place.

[0084] Example 3

[0085] As another embodiment of the present invention, this embodiment provides a lint collection device with a structure similar to that of Embodiment 1, the difference being that in this embodiment, the sealing component is a rubber strip with deformability.

[0086] Furthermore, the collection components also include,

[0087] A fixing groove is used to fix the sealing assembly.

[0088] Furthermore, when the sealing component is fixed in the fixing groove, it partially protrudes from the fixing groove.

[0089] In the above solution, since the rubber strip has a large frictional force, the sealing component is fixed by the fixing groove to avoid the sealing component falling off due to friction during the installation and disassembly of the wire chip collection device, thus reducing the sealing performance.

[0090] The sealing component protrudes from the fixing groove. When the separation component and the collection component are engaged, and when the collection box and the collection part are engaged, the sealing component can provide a certain friction force to improve the stability of the engagement. At the same time, because the sealing component has the ability to deform, the sealing effect is better.

[0091] The present invention also provides a clothes dryer having the above-mentioned lint collection device, specifically:

[0092] Example 4

[0093] As another embodiment of the present invention, this embodiment provides a clothes dryer having a lint collection device as described in Embodiment 1.

[0094] In this embodiment, the lint collection device is located at the front of the dryer, and the separation component 3 is located in the front air duct of the dryer. The dryer includes...

[0095] The mounting section, located on the front side of the dryer, is used to install the collection assembly 2;

[0096] The door body is located at the end of the mounting section and is movably connected to the mounting section;

[0097] When the collecting component 2 is installed in the mounting section, the air guide section 22 is connected to the dryer's circulating air duct.

[0098] In the above scheme, when the collecting component 2 is installed inside the installation part, the door closes to block the collecting box 1 and prevent the collecting box 1 from falling out. At the same time, the door squeezes the collecting box 1 to make the collecting box 1 and the collecting part 21 fit tightly together, which improves the sealing effect of the sealing component.

[0099] Furthermore, the collection component 2 also includes,

[0100] The third positioning rib 25 is formed by folding outward from the end of the collecting part 21 and is used to position the collecting component 2 in place.

[0101] Furthermore, the sealing assembly also includes,

[0102] The fourth sealing part 251 is provided on the side of the third positioning rib 25 facing the dryer;

[0103] When the collection component 2 is installed in place, the fourth sealing part 251 is in close contact with the front panel of the dryer.

[0104] In the above solution, the fourth sealing part 251 achieves a seal between the collecting component 2 and the front panel of the dryer, preventing lint from leaking out of the gaps into the outside of the dryer and affecting the usage environment.

[0105] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
