Description

Technical Field

[0001] This invention belongs to the field of clothes dryers, and specifically relates to a clothes dryer and its lint separation 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 multiple filter layers achieve lint filtration and collection, and the filter device can be removed for cleaning. Although the above solution achieves lint filtration and collection, the lint adhering to the filter screen creates 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. Furthermore, the user needs to manually remove the filter screen for cleaning, which is relatively complicated and reduces the user experience.

[0005] Chinese utility model patent application number CN201920462931.1 discloses a cleaning system for a lint filter, including a spray rinsing device for rinsing lint off the filter and a collection box connected to the lower part of the filter for collecting the lint rinsed off. When disassembling the filter for cleaning, the collection box can be removed and cleaned together. Although the above solution achieves the cleaning of the lint filter and collects the lint rinsed off the filter into the collection box, the airflow speed of the drying air inside the dryer will still change during a single operation as lint adheres, and the use of a rinsing device to clean the lint filter also wastes water resources.

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

[0007] The purpose of this invention is to provide a wire chip separation device that addresses the problems in the prior art by dividing the air duct and filtering and discharging the wire chips in the different air ducts obtained from the division, thereby achieving the separation and discharge of wire chips and avoiding the retention of wire chips in the wire chip separation device that would affect the separation effect.

[0008] Another aspect of the present invention provides a clothes dryer with a lint separator located in the front air duct. By filtering lint and guiding it out, the lint separator eliminates the need for the user to disassemble and clean it, thus improving the user experience.

[0009] To achieve the above objectives, a first aspect of the present invention provides a wire chip separation device, wherein the wire chip separation device is disposed inside an air duct and includes,

[0010] The positioning part is connected to the air inlet of the air duct and is used to position the lint separator in place during installation.

[0011] A partition, connected to the positioning part, extends along the air outlet direction into the interior of the air duct to divide the air duct;

[0012] A filter section, connected to the partition section, is used to filter lint.

[0013] Furthermore, the partition includes,

[0014] The first partition extends into the interior of the air duct along the air outlet direction, thus dividing the air duct.

[0015] The first partition is provided with a connecting port, and the two sides of the first partition are connected through the connecting port. The filter part is provided on one side of the first partition to filter out lint and guide the lint to the connecting port.

[0016] In the above solution, the lint separation device divides the air duct. After the filter part filters the lint, it guides the lint to the connecting port. The lint passes through the connecting port and is discharged from the other side of the first partition, which avoids the lint remaining in the filter part and affecting the filtration effect. Users do not need to remove the filter part for cleaning, which improves the user experience.

[0017] Furthermore, the filtering section includes,

[0018] The first screen plate extends from the lower edge of the connecting opening toward one side of the first partition and is inclined upward, covering the air duct located on that side.

[0019] Furthermore, a lint collection device is provided below the air duct on the side opposite to the side where the filter section is located on the first partition, for collecting lint.

[0020] The above solution filters wire debris through the first screen plate, which is highly efficient and has little impact on the flow of circulating air. At the same time, the first screen plate is set at an angle, which allows the wire debris to pass through the connecting port more smoothly under the guidance of the first screen plate, avoiding the accumulation of wire debris on the first screen plate.

[0021] Furthermore, the partition also includes,

[0022] The second partition extends along the air outlet direction of the air duct and is set close to the air duct wall on one side of the air duct.

[0023] The second partition is parallel to the first partition, and the filter is located between the first partition and the second partition.

[0024] Furthermore, the filtering section includes,

[0025] The first sieve plate extends from the lower edge of the connecting port toward the second partition and is inclined upward.

[0026] The second sieve plate extends from the second partition to the communication port and is inclined downwards.

[0027] The first sieve plate is located below the second sieve plate.

[0028] The above solution achieves multi-stage filtration of lint through the cooperation of the first and second screen plates. The first screen plate is located below the second screen plate. The lint filtered by the second screen plate falls onto the first screen plate under the guidance of the second screen plate, and enters the connecting port under the guidance of the first screen plate, thereby achieving filtration of lint in the circulating air and improving the filtration effect.

[0029] Furthermore, the wire chip separation device also includes,

[0030] The wire chip separation device also includes

[0031] A fixing part is provided on the partition part for fixing the filter part;

[0032] The filter section is detachably connected to the partition section via the mounting section.

[0033] Furthermore, the fixing part is provided with a socket that matches the sieve plate, and the first sieve plate and the second sieve plate are detachably connected to the separating part through the socket on the fixing part.

[0034] Furthermore, rubber pads are provided on both sides of the socket, and the sieve plate fits tightly with the rubber pads when it is connected to the socket, which improves the fixing effect of the fixing part on the sieve plate.

[0035] Alternatively, as an alternative to the above solution, after the sieve plate is inserted into the fixing part, a stable connection between it and the fixing part can be achieved by using glue.

[0036] The above alternative solution achieves a more stable connection between the sieve plate and the fixing part, which can effectively prevent the sieve plate from falling off due to vibration during the filtration process.

[0037] Furthermore, the first partition is provided with a plurality of communication ports at intervals along the air outlet direction, and the lint separation device is provided with a plurality of filter sections accordingly.

[0038] Furthermore, the second partition is provided with an opening located below the second sieve plate near the extended end of the second partition, and is disposed close to the second sieve plate.

[0039] In the above scheme, the opening on the second partition reduces the impact of the wire shavings separation device on the cross-sectional area of ​​the air duct, and at the same time reduces production costs. The opening is located below the second screen plate near the extension end of the second partition, so as to avoid the wire shavings adhering to the opening during the wire shavings filtration process and affecting the wire shavings filtration effect.

[0040] The partition also includes,

[0041] The third partition is parallel to the second partition and is located in the air duct on the opposite side to the side with the second partition.

[0042] In the above scheme, the second and third partitions are respectively set close to the two opposite side walls of the air duct, which realizes the fixation of the wire chip separation device and improves the installation stability of the wire chip separation device by cooperating with the positioning part.

[0043] Furthermore, the sides of the partition have a reinforcing structure, which reduces the risk of the partition being deformed by compression and improves the stability of the partition.

[0044] Furthermore, the wire chip separation device also includes,

[0045] A connecting plate is disposed on both sides of the partition to connect the first partition and the third partition;

[0046] The wall surface of the connecting plate is connected to the first partition and the third partition.

[0047] In the above scheme, the connecting plate connects the first partition and the third partition, which improves the strength of the wire chip separation device and fixes the first partition, preventing it from shaking under the influence of circulating air and affecting the wire chip filtration effect. If the connecting plate connects the first partition and the second partition, the area of ​​the air duct on the side with the filter will be reduced, thus affecting the wire chip separation effect. The wall of the connecting plate is connected to the first partition and the third partition to prevent wire chips from adhering to the side of the connecting plate when passing through the connecting port, and at the same time, it allows the wire chip separation device to be installed more smoothly in the air duct.

[0048] Furthermore, the positioning part is provided with,

[0049] The flow stabilizer is located on the side of the positioning part facing the outside of the air duct, and is used to keep the flow of circulating air entering the wire chip separation device stable.

[0050] The above solution guides the circulating air through the flow stabilizer, keeping the flow of the circulating air entering the wire chip separation device stable, allowing the circulating air to pass through the wire chip separation device more smoothly, thus improving the wire chip separation effect.

[0051] Furthermore, the flow stabilizing ribs include a first flow stabilizing rib disposed parallel to the partition portion, and a second flow stabilizing rib perpendicular to the first flow stabilizing rib.

[0052] In the above scheme, the first and second flow stabilizing ribs strengthen the positioning part and achieve full cooperation between the positioning part and the cavity, while stabilizing the flow state of the circulating air. This prevents the circulating air from flowing randomly after entering the wire chip separation device, which would prevent the wire chips from passing smoothly through the sieve plate for separation and collection, thus reducing the wire chip separation effect.

[0053] A second aspect of the present invention provides a clothes dryer having the lint separation device described in the above-described scheme.

[0054] Furthermore, the partition has the same width as the air duct, and the width of the positioning part is greater than the width of the partition.

[0055] Furthermore, the lint separator is located in the front air duct of the dryer, and the air inlet of the front air duct passes through the lower edge of the window gasket, forming a cavity in the window gasket. The lint separator is installed into the front air duct through the cavity.

[0056] Furthermore, the width of the cavity is greater than the width of the front air duct, and it has a shape that matches the positioning part. The two ends of the first flow-stabilizing rib are curved. When the lint separator is installed in place, the first flow-stabilizing rib can match the curvature of the window gasket. Simultaneously, the arrangement of the first flow-stabilizing rib on the positioning part matches the curvature of the window gasket. This design allows for a smooth fit between the window gasket and the flow-stabilizing rib, improving the aesthetics of the lint separator. It has a structure that matches the curvature of the window gasket surface, and when the lint separator is installed in place, the flow-stabilizing rib on the positioning part smoothly connects to the surface of the window gasket.

[0057] In the above solution, the airflow stabilizer is smoothly connected to the surface of the window gasket, which improves aesthetics and user experience while guiding the circulating air.

[0058] The beneficial effects of this invention are as follows:

[0059] The first partition is fixed inside the air duct by a positioning part. A filter section located on one side of the first partition filters the lint in the circulating air and guides the lint to the other side of the first partition for further filtration and collection, thus achieving lint separation and collection. The second partition is parallel to the first partition and is located close to one side of the air duct. Screen plates are respectively installed on the first and second partitions, achieving multi-stage filtration of lint and increasing the residence time of the circulating air within the lint separation device, thereby improving the lint separation effect. The screen plates are detachably connected to the partitions via a fixing part, allowing for individual replacement when damaged after prolonged use, reducing replacement costs. The third partition is parallel to the second partition and is located close to the other side of the air duct opposite to the second partition. The device is secured by the second and third partitions, which, in conjunction with the positioning unit, further enhance its installation stability. The third and first partitions are connected by a connecting plate, which, while increasing the strength of the device, also secures the first partition, preventing it from swaying under the influence of circulating air and affecting the lint separation effect. The flow-stabilizing ribs on the positioning unit strengthen the unit, preventing deformation, and guide the circulating air to maintain stability, allowing it to smoothly pass through the lint separator and filter lint. These crisscrossing arc-shaped ribs connect smoothly to the window gasket surface when the positioning unit is in place, improving aesthetics while guiding the circulating air and enhancing the user experience.

[0065] Example 1

[0066] As one embodiment of the present invention, this embodiment provides a wire chip separation device, including,

[0067] Positioning unit 1 is connected to the air inlet of the air duct and is used to position the installation of the wire chip separation device in place;

[0068] The partition 2 is connected to the positioning part 1 and extends along the air outlet direction into the interior of the air duct to divide the air duct;

[0069] The filter section 3 is connected to the partition section 2 and is used to filter lint.

[0070] In this embodiment, the partition 2 includes a first partition 21, a second partition 22 and a third partition 23 that are parallel to each other. A connecting port is provided on the first partition 21 to connect the two sides of the first partition 21. The filter part 3 is located between the first partition 21 and the second partition 22. While filtering the lint in the circulating air, it guides the lint to the connecting port. The lint reaches the other side of the first partition 21 through the connecting port for collection and discharge.

[0071] Furthermore, the side of the partition 2 has a reinforcing structure, which reduces the risk of the partition 2 being deformed by compression and improves the stability of the partition 2.

[0072] Furthermore, the filter unit 3 includes,

[0073] The first sieve plate 31 extends from the lower edge of the communication port toward the second partition 22 and is inclined upward.

[0074] The second sieve plate 32 extends from the second partition 22 toward the communication port and is inclined downward.

[0075] The first sieve plate 31 is located above the second sieve plate 32.

[0076] In the above scheme, the cooperation of the first screen plate 31 and the second screen plate 32 realizes multi-stage filtration of wire debris. The first screen plate 31 is located below the second screen plate 32. The wire debris filtered by the second screen plate 32 falls onto the first screen plate 31 under the guidance of the second screen plate 32, and enters the connecting port under the guidance of the first screen plate 31, thereby realizing the filtration of wire debris in the circulating air and improving the filtration effect.

[0077] Furthermore, a fixing part is provided on the first partition 21 and the second partition 22, and a socket with a matching structure is connected. The sieve plate is fixed on the first partition 21 and the second partition 22 by the fixing part and is detachably connected to the first partition 21 and the second partition 22.

[0078] Furthermore, rubber pads are provided on opposite sides inside the socket. When the sieve plate is connected to the socket, it fits tightly with the rubber pads, and the friction force achieves a tight connection with the fixing part, thereby improving the fixing effect of the fixing part on the sieve plate.

[0079] Furthermore, the distance between the first partition 21 and the second partition 22 is greater than the distance between the first partition 21 and the third partition 23.

[0080] The above scheme allows more circulating air to enter between the first partition 21 and the second partition 22 for wire chip separation, thus improving the wire chip separation effect.

[0081] Furthermore, the positioning part 1 is provided with,

[0082] The flow stabilizer 11 is located on the side of the positioning part 1 facing the outside of the front air duct, and is used to keep the flow of the circulating air entering the lint separator stable.

[0083] The above solution guides the circulating air through the flow stabilizer 11, keeping the flow of the circulating air entering the wire chip separation device stable, allowing the circulating air to pass through the wire chip separation device more smoothly, thus improving the wire chip separation effect.

[0084] Furthermore, the flow stabilizing rib 11 includes a first flow stabilizing rib 111 disposed parallel to the partition portion 2, and a second flow stabilizing rib 112 perpendicular to the first flow stabilizing rib 111.

[0085] In the above scheme, the first flow stabilizer rib 111 and the second flow stabilizer rib 112 strengthen the positioning part 1 and achieve full cooperation between the positioning part 1 and the cavity, while stabilizing the flow state of the circulating air and preventing the circulating air from flowing disorderly after entering the wire chip separation device. This would prevent the wire chips from passing smoothly through the sieve plate for separation and collection, thus reducing the wire chip separation effect.

[0086] Example 2

[0087] As another embodiment of the present invention, this embodiment provides a lint separation device with the same structure as the first embodiment. The difference is that, in this embodiment, two connecting ports are provided at intervals along the air outlet direction on the first partition 21, and two filter parts 3 are provided between the first partition 21 and the second partition 22 corresponding to the connecting ports.

[0088] Furthermore, the second partition 22 is provided with an opening 4, which is located below the second sieve plate 32 near the extended end of the second partition 22 and is set close to the second sieve plate 32.

[0089] The above solution reduces the impact of the wire lint separation device on the cross-sectional area of ​​the air duct by installing it in the air duct through the opening 4 on the second partition 22, and at the same time reduces the production cost. The opening 4 is located below the second screen plate 32 near the extension end of the second partition 22, so as to avoid the wire lint adhering to the opening 4 during the wire lint filtration process and affecting the wire lint filtration effect.

[0090] Example 3

[0091] As another embodiment of the present invention, this embodiment provides a wire chip separation device with the same structure as in Embodiment 1, the difference being that, in this embodiment, the wire chip separation device further includes,

[0092] A connecting plate is disposed on both sides of the partition to connect the first partition and the third partition.

[0093] The above solution improves the strength of the lint separation device by using a connecting plate, and avoids the first interval from shaking under the influence of circulating air, which would affect the lint filtration effect.

[0094] Furthermore, since the filter section is located between the first partition section and the second partition section, the connection between the first partition section and the third partition section via the connecting plate will not affect the cross-sectional area of ​​the air duct on the side where the filter section is located, and will not affect the lint separation effect.

[0095] Furthermore, the wall surface of the connecting plate is connected in conjunction with the first partition and the third partition.

[0096] With the above solution, the wire chip separation device can be installed more smoothly inside the air duct, avoiding interference between the wire chip separation device and the air duct, which may lead to improper installation or deformation of the wire chip separation device, thus reducing the wire chip separation effect. At the same time, it also prevents wire chips from adhering to the side of the connecting plate when passing through the connection port, thus preventing wire chip accumulation from affecting the wire chip collection and separation effect.

[0097] Example 4

[0098] As another embodiment of the present invention, this embodiment provides a wire chip separation device with the same structure as the first embodiment. The difference is that, in this embodiment, the sieve plate is connected to the fixing part by glue after being inserted into the socket.

[0099] The above solution achieves detachable screen plates while using glue to tightly connect the screen plates and the fixing parts. Since the screen plates may vibrate during the filtration process, connecting the screen plates and the fixing parts with glue prevents the screen plates from falling off and improves the stability of the wire chip separation device.

[0100] Example 5

[0101] As another embodiment of the present invention, this embodiment provides a wire chip separation device, including,

[0102] The positioning part is connected to the air inlet of the air duct and is used to position the lint separator in place during installation.

[0103] A partition, connected to the positioning part, extends along the air outlet direction into the interior of the air duct to divide the air duct;

[0104] A filter section, connected to the partition section, is used to filter lint.

[0105] In this embodiment, the partition includes a first partition extending along the air outlet direction of the air duct. A connecting port is provided on the first partition to connect the two sides of the first partition. The filter is located on one side of the first partition and guides the lint in the circulating air to the connecting port while filtering the lint, and discharges it from the other side of the first partition.

[0106] Furthermore, the filtration section includes,

[0107] The first screen plate extends from the lower edge of the communication port toward one side of the first partition and is inclined upward, covering the air duct located on that side.

[0108] In the above scheme, the first screen plate covers the air duct on one side of the first partition, which realizes the full filtration of the wire debris on that side. The filtered wire debris passes through the connecting port to the other side of the first partition, and is collected by the collection device or directly discharged from the air duct, thereby realizing the full separation of wire debris.

[0109] The present invention also provides a clothes dryer having the above-mentioned lint separation device, specifically:

[0110] Example 6

[0111] As another embodiment of the present invention, this embodiment provides a clothes dryer having a lint separation device as described in Embodiment 1.

[0112] In this embodiment, the air inlet of the front air duct of the dryer passes through the lower edge of the dryer window pad, forming a cavity inside the window pad. The lint separator is detachably installed inside the front air duct of the dryer through the cavity.

[0113] Furthermore, the width of the cavity is greater than the width of the front air duct, and the positioning part 1 has a shape that matches the cavity.

[0114] Furthermore, the positioning part 1 is provided with,

[0115] The flow stabilizer 11, with the positioning part 1 facing the outside of the front air duct, is used to keep the flow of the circulating air entering the lint separator stable.

[0116] The flow stabilizing rib 11 includes a first flow stabilizing rib 111 parallel to the partition 2 and a second flow stabilizing rib 112 perpendicular to the first flow stabilizing rib 111. By strengthening the positioning part 1 through the first flow stabilizing rib 111 and the second flow stabilizing rib 112, the positioning part 1 and the cavity can be fully matched, while stabilizing the flow state of the circulating air. This prevents the circulating air from flowing disorderly after entering the wire chip separation device, which would prevent the wire chips from passing smoothly through the filter part 3 for separation and collection, thus reducing the wire chip separation effect.

[0117] Furthermore, the first flow stabilizer 111 has curved ends. When the positioning part 1 is installed in place, the first flow stabilizer 111 can match the curvature of the window gasket. At the same time, the arrangement of the first flow stabilizer 111 on the positioning part 1 matches the curvature of the window gasket. In this way, the window gasket and the flow stabilizer 11 can be smoothly matched, which improves the aesthetics of the lint separation device.

[0118] 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.
