A lint separating device and a laundry drying apparatus

Abstract

The application discloses a lint separating device and a clothes drying equipment. The lint separating device is arranged in a front air duct of the clothes drying equipment, and divides the front air duct into a first air duct and a second air duct which are arranged side by side in the same direction. The second air duct is provided with a first filter screen which is arranged in a slanting manner along an air outlet direction and towards the first air duct, and a first sieve plate and a second sieve plate which are arranged in the same slanting manner as the first filter screen or a second filter screen. The circulating air entering the second air duct is fully separated from the lint after being filtered by the sieve plates and the filter screens. Since the sieve plates and the filter screens are arranged in a slanting manner, the lint adhered to the sieve plates and the filter screens can move along the slanting direction under the action of gravity and the circulating air, and enter the first air duct through a communication port which communicates the first air duct and the second air duct. The lint separating device realizes real-time cleaning of the filtering assembly during the lint filtering process, and avoids the influence of the lint adhesion on the filtering effect of the filtering assembly.

Description

Technical Field

[0001] This invention belongs to the field of laundry and drying technology, and specifically relates to a lint separation device and a clothing drying equipment. Background Technology

[0002] Because clothes contain lint and dander, during the operation of clothes drying equipment, lint and dander inevitably flow with the drying air and are blocked by the dander filter, remaining on the dander filter. With prolonged use of the drying equipment, the filter becomes covered and clogged with lint and dander, preventing the drying air from flowing smoothly and significantly affecting the working efficiency of the clothes drying equipment.

[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 invention patent application number CN202010411861.4 discloses a clothes drying device, specifically disclosing a detachable filter installed in the air duct of the clothes dryer. The filter includes a housing with an air inlet and an air outlet. A filtration air duct is formed inside the housing, and a filter screen covers the cross-section of the air duct. The filter screen is detachably installed in the air duct and arranged side by side at intervals along the air outlet direction for filtering lint. Although the above solution discloses a method of filtering lint by setting multiple layers of detachable filter screens along the air outlet direction, the lint separated during operation still remains in the filter, affecting the drying efficiency of the clothes dryer. Furthermore, users need to clean the filter frequently, reducing the user experience.

[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 separation device to address the problems in the prior art. The device is installed inside the air duct of a clothes drying equipment and includes a first air duct and a second air duct arranged in the same direction and side by side. A filter component is installed in the second air duct. The filter component guides the filtered lint into the first air duct through a connecting port, thereby achieving full separation of lint and avoiding the retention of lint in the filter component, which would affect the filtration effect.

[0008] Another aspect of the present invention provides a clothes drying device with a lint separation device. The first air duct of the lint separation device is connected to the outside of the clothes drying device, and the second air duct is connected to the circulating air duct of the clothes drying device. It can separate and discharge lint while drying clothes, effectively avoiding the need for users to frequently disassemble and clean the lint separation device, and improving the user experience.

[0009] To achieve the above objectives, a first aspect of the present invention provides a lint separation device, disposed inside the air duct of a clothes drying equipment, comprising a first air duct and a second air duct arranged side by side in the same direction, wherein the second air duct contains...

[0010] The filter assembly includes a filter screen that is inclined toward the side closer to the first air duct along the air outlet direction for filtering lint;

[0011] The first air duct and the second air duct are connected by a connecting port, and the filter assembly guides the lint through the connecting port into the first air duct.

[0012] Specifically, the circulating air enters the second air duct and is fully separated from the lint by the filter component. The separated lint is guided by the filter component and enters the first air duct through the connecting port, which avoids the filtered lint from staying in the filter component and causing blockage, thus affecting the circulation efficiency of the circulating air. At the same time, the separated lint is collected through the first air duct, which prevents the lint from affecting the lint filtration effect.

[0013] Furthermore, the filtering components include,

[0014] The first filter screen covers the cross-section of the second air duct;

[0015] The connection port includes a first connection port, and the end of the first filter screen near the first air duct is connected to the lower edge of the first connection port.

[0016] In the above scheme, the first filter extends along the air outlet direction and is inclined towards the first air duct, covering the cross-section of the second air duct. This can effectively separate the lint in the circulating air entering the second air duct, while using the inclined surface of the first filter to guide the lint towards the connection port. Then, under the guidance of the inclined surface and the push of the circulating air, the lint passes through the connection port and enters the first air duct, effectively avoiding the lint remaining on the first filter and affecting the circulation efficiency of the circulating air.

[0017] Furthermore, the filtering components also include,

[0018] The first sieve plate is located in front of the first filter screen along the air outlet direction;

[0019] The communication port includes a second communication port, and the first sieve plate extends outward from the lower edge of the second communication port.

[0020] In the above scheme, the circulating air entering the second air duct is first filtered by the first screen plate. Most of the lint and fuzz are blocked by the first screen plate and enter the first air duct through the second connecting port under the guidance of the first screen plate. Most of the lint in the circulating air filtered by the first screen plate has been filtered. The remaining small amount of lint is blocked when passing through the first filter screen and enters the first air duct through the first connecting port under the guidance of the first filter screen. The filtration effect is improved by filtering the circulating air multiple times. At the same time, since the filter screen is prone to deformation under the pressure of the circulating air and lint, a single-layer filter screen is prone to damage after deformation or reduced guidance effect on lint. By placing the first screen plate in front of the first filter screen, the filtration pressure of the first filter screen is reduced, which improves the filtration effect and extends the service life of the first filter screen.

[0021] Furthermore, the first screen plate partially covers the cross-section of the second air duct, and the filter assembly also includes,

[0022] The second screen plate is located in front of the first screen plate along the air outlet direction, and is obtained by extending obliquely from the side of the second air duct away from the first air duct along the air outlet direction.

[0023] The second sieve plate works in conjunction with the first sieve plate to cover the cross-section of the second air duct.

[0024] In the above scheme, the first and second screen plates are staggered along the air outlet direction, which, together with the cross-section covering the second air duct, increases the time for the circulating air to pass through the first and second screen plates, effectively improving the lint filtration effect. At the same time, the cross-sections of the first and second screen plates that partially cover the second air duct both have a free end, which can vibrate under the blowing of the circulating air. Through vibration, the lint can be guided to the second connection port more quickly, avoiding the lint from remaining on the screen plate for a long time and reducing the obstruction effect on the circulating air.

[0025] Even if there are still lint particles in the circulating air after filtration by the first and second screens, their content is relatively low. The remaining lint particles can be easily intercepted by the first filter screen, thus achieving sufficient filtration of lint particles.

[0026] Furthermore, the first sieve plate is parallel to the second sieve plate.

[0027] Furthermore, the angle between the filter and the air outlet direction is smaller than the angle between the sieve plate and the air outlet direction.

[0028] In the above solution, the sieve plate has a certain hardness and can guide the lint through vibration. However, the filter screen is made of soft material, and if it undergoes large deformation, it is easy to be damaged or the guiding effect on the lint will be reduced. Therefore, the angle between the filter screen and the air outlet direction is smaller than the angle between the sieve plate and the air outlet direction. The lint blocked by the filter screen can be more easily removed from the filter screen under the action of gravity and circulating air, thereby avoiding large deformation of the filter screen. This improves the lint filtration effect and extends the service life of the filter screen.

[0029] Alternatively, as an alternative to the above solution, the filter assembly includes a second filter screen, which is arranged side by side with the first filter screen along the air outlet direction and covers the cross-section of the second air duct.

[0030] The connection port includes a third connection port, and the end of the second filter screen near the first air duct is connected to the lower edge of the third connection port.

[0031] In the above alternative, instead of setting a sieve plate in the second air duct, two layers of filter screens are set up. The lint is filtered multiple times through the two layers of filter screens, which reduces production costs while achieving a better filtration effect. Since the first and second filter screens are set at an angle, the air resistance and resistance caused by lint are smaller, and the service life is also extended accordingly.

[0032] Preferably, the angle between the second filter and the air outlet direction is greater than the angle between the first filter and the air outlet direction.

[0033] In the above scheme, the first filter first filters the circulating air. At this time, there are more lint particles in the circulating air, which can easily damage the first filter if accumulated over a long period of time. Therefore, the angle between the first filter and the air outlet direction is smaller than the angle between the second filter and the air outlet direction. When filtering lint particles, the lint particles can enter the first air duct through the first connecting port more quickly under the action of the circulating air and gravity. After being filtered by the first filter, there are only a few lint particles left in the circulating air that were not filtered by the first filter. That is, the filtration pressure of the second filter is smaller. Therefore, the angle between the second filter and the air outlet direction is larger than the angle between the first filter and the air outlet direction. While achieving sufficient filtration of residual lint particles, the area of ​​the filter is reduced, thereby avoiding large deformation of the filter. This further reduces production costs while achieving sufficient filtration of lint particles.

[0034] Furthermore, the first filter screen and the second filter screen are spaced apart. The ends of the first filter screen and the second filter screen away from the first air duct are fixed to the upper part of the second air duct, and the ends of the first filter screen and the second filter screen closer to the first air duct are fixed to the lower part of the second air duct. According to the actual production situation, the first filter screen and the second filter screen are always at a large tilt angle, which reduces the probability of wire debris adhesion and makes it easier for wire debris to detach from the filter screen.

[0035] A second aspect of the present invention provides a clothing drying device employing the lint separation device described above.

[0036] Specifically, the lint separation device is located in the front air duct of the clothes drying equipment. The second air duct is connected to the circulating air duct of the clothes drying equipment, and the first air duct is connected to the outside of the clothes drying equipment. The lint separated in the second air duct is guided by the filter component to pass through the connection port into the first air duct, and then discharged from the first air duct to the outside of the clothes drying equipment, or discharged from the first air duct and collected.

[0037] In the above scheme, the cross-sectional area of ​​the second air duct is larger than that of the first air duct. Most of the circulating air can be filtered and circulated through the second air duct, avoiding the large amount of circulating air discharged, which would cause the drying temperature to drop.

[0038] The beneficial effects of this invention are as follows:

[0039] 1. The front air duct of the clothes drying equipment is divided into a first air duct and a second air duct that are connected to each other through a connecting port by a lint separator. The filter component in the second air duct filters the lint and guides it to the connecting port. The lint enters the first air duct through the connecting port for collection or discharge, thus avoiding the lint from remaining in the filter component and affecting the filtration effect and normal circulation of the air.

[0040] 2. The filter assembly includes a first screen plate, a second screen plate, and a first filter screen arranged sequentially along the air outlet direction. The first screen plate and the second screen plate filter most of the lint in the circulating air, reducing the filtration pressure of the first filter screen and preventing the first filter screen from deforming significantly due to increased air resistance caused by a large amount of lint, which would lead to damage to the first filter screen.

[0041] 3. The filter assembly includes a first filter and a second filter, which significantly reduces production costs while filtering lint.

[0042] 4. The lint entering the first air duct can be discharged directly or collected after passing through the first air duct. Users only need to clean the collected lint regularly to ensure the normal operation of the lint separator. There is no need to frequently remove the lint separator for separate cleaning, which improves the user experience. Attached Figure Description

[0051] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Those skilled in the art will understand that the following embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0052] In the description of this invention, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0054] This invention discloses a wire chip separation device, such as... Figures 1 to 7 As shown, the lint separator is located inside the air duct of the clothes drying equipment, including a first air duct 1 and a second air duct 2 arranged side by side in the same direction. The second air duct 2 contains...

[0055] The filter assembly includes a filter screen that is inclined toward the side closer to the first air duct 1 along the air outlet direction for filtering lint.

[0056] The first air duct 1 and the second air duct 2 are connected by a connecting port, and the filter component guides the lint through the connecting port into the first air duct 1.

[0057] In the above scheme, the filter assembly guides the filtered lint into the first air duct 1 through the connecting port, achieving full separation of the lint and preventing lint from remaining in the filter assembly and affecting the filtration effect. The filter assembly always remains in a state with little or no lint attached, which does not affect the normal circulation of the circulating air and improves the drying efficiency. At the same time, using a filter screen as the filter assembly, by setting the filter screen at an angle, not only is it possible to avoid a large amount of lint adhering, but it is also possible to avoid the increase in air resistance caused by lint adhering. As a result, the filter screen will not undergo significant deformation during use, which improves the service life of the filter screen and the working stability of the lint separation device.

[0058] The present invention will now be further described with reference to specific embodiments.

[0059] Example 1

[0060] As an embodiment of the present invention, this embodiment provides a lint separation device. In this embodiment, the filter assembly is disposed within the second air duct 2, such as... Figure 4 As shown, it includes a first sieve plate 5, a second sieve plate 6, and a first filter screen 3, with the specific structure as follows.

[0061] The first screen plate 5, the second screen plate 6, and the first filter screen 3 are arranged sequentially and at intervals along the air outlet direction in the second air duct 2. The first screen plate 5 and the first filter screen 3 are connected to the side wall of the second air duct 2 near the first air duct 1. The connecting ports include a second connecting port 8 corresponding to the position of the first screen plate 5 and a first connecting port 7 corresponding to the position of the first filter screen 3. The second screen plate 6 is located above the first screen plate 5 and is connected to the side wall of the second air duct 2 away from the first air duct 1. The first filter screen 3 covers the cross section of the second air duct 2. When the circulating air passes through the first screen plate 5 and the second screen plate 6, the wire debris is blocked and separated from the circulating air by the first screen plate 5 and the second screen plate 6. Wire debris may still be present in the circulating air filtered by the first screen plate 5 and the second screen plate 6. By setting the first filter screen 3, the circulating air after being filtered by the screen plate can be filtered a second time, thus achieving sufficient filtration of wire debris.

[0062] Meanwhile, the lint filtered by the first screen plate 5 and the second screen plate 6 is guided by the inclined screen plates and enters the first air duct 1 through the second connecting port 8. The lint blocked by the first filter screen 3 falls along the inclined first filter screen 3 under the action of circulating air and gravity, passes through the first connecting port 7 and enters the first air duct 1, thus achieving full separation of lint and filter components and avoiding lint remaining in the filter components and affecting the normal circulation of circulating air.

[0063] Furthermore, to further prevent lint from adhering to the filter assembly, the first screen plate 5 and the second screen plate 6 are configured to partially cover the cross-section of the second air duct 2. That is, the first screen plate 5 covers the side of the second air duct 2 closest to the first air duct 1, and the second screen plate 6 covers the side of the second air duct 2 away from the first air duct 1. Through the cooperation of the first screen plate 5 and the second screen plate 6, the cross-section of the second air duct 2 is fully covered. While achieving sufficient filtration of lint, the first screen plate 5 and the second screen plate 6 can vibrate under the blowing of the circulating air, further preventing lint residue. The lint can be guided to detach from the first screen plate 5 and the second screen plate 6, further preventing lint from remaining on the filter assembly.

[0064] The above scheme, while satisfying the requirements of the sieve plate for blocking and separating wire debris, allows the wire debris to detach from the sieve plate more quickly through the staggered arrangement of the first sieve plate 5 and the second sieve plate 6.

[0065] In order to achieve the vibration of the first sieve plate 5 and the second sieve plate 6, the first sieve plate 5 and the second sieve plate 6 are made of materials with certain toughness and deformation recovery ability, such as metal and plastic, and preferably metal materials.

[0066] Conventional improvements made by those skilled in the art to the arrangement of the first sieve plate 5 and the second sieve plate 6 based on the known principles of the present invention also fall within the protection scope of the present invention. For example, changing the coverage area of ​​the first sieve plate 5 and the second sieve plate 6, or changing the inclination and extension direction of the first sieve plate 5 and the second sieve plate 6, or changing the material of the first sieve plate 5 and the second sieve plate 6.

[0067] Furthermore, in order to improve the filtration effect, it is preferable that the cross-section of the air duct covered by the first screen plate 5 and the second screen plate 6 overlaps.

[0068] Furthermore, such as Figure 5 As shown, the angle between the first filter screen 3 and the air outlet direction is smaller than the angle between the sieve plate and the air outlet direction, which avoids the first filter screen 3 from being damaged due to large deformation during the filtration process and improves the service life of the first filter screen 3.

[0069] Furthermore, a protruding structure 101 is provided inside the first air duct 1 on the side opposite to the connection port. The protruding structure 101 is opposite to the connection port. When the circulating air sends the wire scraps into the first air duct 1, the change in cross-sectional area generates the Venturi effect, which allows the wire scraps to pass through the connection port more smoothly and improves the efficiency of wire scrap discharge.

[0070] Example 2

[0071] As another embodiment of the present invention, this embodiment provides a wire chip separation device, which differs from Embodiment 1 in that, in this embodiment, as... Figure 6 As shown, the filter assembly includes a first filter 3 and a second filter 4.

[0072] Furthermore, the first filter 3 and the second filter 4 are arranged at intervals along the air outlet direction. The first filter 3 is located in front of the second filter 4. The connection port includes a first connection port 7 and a third connection port 9. The end of the first filter 3 near the first air duct 1 is connected to the lower edge of the first connection port 7, and the end of the second filter 4 near the first air duct 1 is connected to the lower edge of the third connection port 9.

[0073] Specifically, the circulating air entering the second air duct 2 first passes through the first filter 3. After the first filter 3 intercepts the lint in the circulating air, due to the inclined setting of the first filter 3, the lint moves along the inclined direction of the first filter 3 under the combined action of the circulating air and gravity and finally passes through the first connecting port 7 to enter the first air duct 1. Then the circulating air continues to pass through the second filter 4. The lint that was not intercepted by the first filter 3 will be blocked by the second filter 4. Due to the inclined setting of the second filter 4, the blocked lint moves along the inclined direction of the second filter 4 under the combined action of the circulating air and gravity and finally passes through the third connecting port 9 to enter the first air duct 1. Through the first filter 3 and the second filter 4, the lint is intercepted multiple times, and the lint is fully separated.

[0074] Because the filter material is relatively soft, it is easily damaged under pressure and deformation, such as Figure 7 As shown, considering the actual working conditions of the lint separation device, the angle between the second filter screen 4 and the air outlet direction is set to be greater than the angle between the first filter screen 3 and the air outlet direction. Since the first filter screen 3 is in front of the second filter screen 4, the amount of lint filtered by the first filter screen 3 is greater than that of the second filter screen 4. The larger the tilt angle of the first filter screen 3, the less likely the blocked lint will adhere to the first filter screen 3, thus avoiding the large pressure exerted by the circulating air on the filter screen when a large amount of lint adheres, which would cause the filter screen to deform and break. The working pressure of the second filter screen 4 is relatively small, and it can work normally without a large angle, thus reducing production costs.

[0075] Furthermore, the tilt angle of the first filter screen 3 and the second filter screen 4 can be adjusted according to the actual structure of the lint separation device. Specifically, the ends of the first filter screen 3 and the second filter screen 4 away from the first air duct 1 are fixed to the upper part of the second air duct 2, and the ends of the first filter screen 3 and the second filter screen 4 close to the first air duct 1 are fixed to the lower part of the second air duct 2. According to the actual production situation, the first filter screen 3 and the second filter screen 4 are always at a large tilt angle, which reduces the probability of lint adhesion and makes it easier for lint to detach from the filter screen.

[0076] Those skilled in the art will understand that solutions obtained by replacing or simply moving the positions of the first filter 3 and the second filter 4 based on knowledge of the technical solutions of this invention also fall within the protection scope of this invention.

[0077] Example 3

[0078] As another embodiment of the present invention, this embodiment provides a lint separation device, which differs from the first embodiment in that the filter assembly includes a first sieve plate 5 and a first filter screen 3, and its specific structure is as follows.

[0079] In this embodiment, as Figure 3As shown, the first screen plate 5 and the first filter screen 3 are spaced apart along the air outlet direction. The first screen plate 5 is located in front of the first filter screen 3, and the first screen plate 5 and the first filter screen 3 respectively cover the cross-section of the second air duct 2. The circulating air entering the second air duct 2 is first filtered by the first screen plate 5. Since the first screen plate 5 covers the cross-section of the second air duct 2, it can filter the wire debris more thoroughly. The filtered wire debris is guided by the first screen plate 5 and enters the first air duct 1 through the second connecting port 8, avoiding the wire debris remaining on the first screen plate 5 and affecting the filtration effect. Since the first screen plate 5 can filter most of the wire debris, only a small amount of wire debris remains in the circulating air after being filtered by the first screen plate 5. When passing through the first filter screen 3, the remaining wire debris can also be fully separated, thereby achieving full filtration of the wire debris. The small amount of wire debris blocked by the first filter screen 3 is guided by the first filter screen 3 and enters the first air duct 1 through the first connecting port 7, avoiding the wire debris remaining on the first filter screen 3 and affecting the filtration effect, and also avoiding affecting the circulation efficiency of the circulating air.

[0080] The above solution places the first filter screen 3 on the rear side of the first screen plate 5, and the first screen plate 5 shares most of the filtration pressure. Since the working pressure of the first filter screen 3 is relatively small, it has a longer service life, reduces the frequency of repair and maintenance of the lint separation device by the user, and improves the user experience.

[0081] Example 4

[0082] As another embodiment of the present invention, this embodiment is further improved on the basis of embodiment one as follows.

[0083] In this embodiment, as Figures 3 to 6 As shown, the wire chip separation device also includes,

[0084] The positioning part 10 is located at the air inlet end of the wire chip separation device and is used to position the wire chip separation device in place during installation.

[0085] The positioning part 10 is provided with a guide rib 11. The guide rib 11 is formed by the side wall shared by the first air duct 1 and the second air duct 2 extending in the opposite direction to the air inlet direction. When the circulating air approaches the positioning part 10, most of the circulating air enters the second air duct 2 due to the obstruction of the guide rib 11. Only a small part of the circulating air passes through the guide rib 11 and enters the first air duct 1, which avoids the loss of circulating air during the lint filtration process and helps to maintain the temperature of the circulating air.

[0086] Furthermore, the end of the guide rib 11 bends towards the direction of the second air duct 2, which further improves the guiding effect on the circulating air.

[0087] The present invention also provides a clothes drying device having the lint separation device described in the above embodiments, specifically as follows:

[0088] Example 5

[0089] As another embodiment of the present invention, this embodiment provides a clothing drying device having a lint separation device as described in Embodiment 3.

[0090] In this embodiment, the clothes drying equipment is a clothes dryer. The lint separator is located in the front air duct of the clothes dryer. The air inlet of the front air duct passes through the lower edge of the dryer window pad, forming a cavity in the window pad. The lint separator is detachably installed inside the front air duct of the clothes dryer through the cavity. When the lint separator is installed in place, the positioning part 10 is embedded and fixed in the cavity, thereby fixing and positioning the lint separator.

[0091] Furthermore, the dryer is equipped with a circulating air duct. When the lint separation device is installed, the second air duct 2 is connected to the circulating air duct, and works with the circulating air duct to achieve normal circulation of the circulating air. The first air duct 1 is connected to the outside of the dryer, which can discharge lint to the outside of the dryer in real time during the drying process, avoiding the accumulation of lint in the dryer and affecting the drying effect.

[0092] Alternatively, as an alternative to the above solution, the air outlet of the first air duct 1 can be connected to a lint collection device to collect the lint discharged from the first air duct 1. Preferably, the lint collection device is detachable from the dryer body, so that users can disassemble and clean the lint collection device regularly to avoid excessive lint accumulation affecting the filtration effect.

[0093] Example 6

[0094] As another embodiment of the present invention, this embodiment is further improved on the basis of embodiment four as follows.

[0095] In this embodiment, the dryer includes a lint collection assembly located below the lint separation device. The lint collection assembly includes a first chamber and a second chamber. The first chamber and the second chamber are respectively provided with a first opening and a second opening above them. The first chamber is connected to the air outlet of the first air duct 1 through the first opening, and the second chamber is connected to the air outlet of the second air duct 2 through the second opening. The second air duct 2 is connected to the circulating air duct of the dryer through the second chamber.

[0096] Specifically, in this embodiment, to prevent lint from being directly discharged into the first chamber and affecting the external environment, a detachable collection box is provided in the first chamber. The collection box has an opening for lint to enter, realizing the unified collection of lint. Users can clean the collection box regularly to ensure that the lint filtered by the filter component can be discharged and collected smoothly, without affecting the normal operation of the filter component due to excessive accumulation of lint, and without affecting the external environment of the clothes drying equipment, thus improving the user experience.

[0097] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
