Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, specifically providing a drying device. Background Technology

[0002] Drying equipment refers to machines that use hot air to dry clothes. Drying equipment mainly includes washer-dryer combos, dryers, or tumble dryers.

[0003] Taking washer-dryer combos as an example, most existing washer-dryer combos on the market use electric heating or heat pump heating. Regardless of the heating method chosen, the dryer still relies on a circulating airflow during the drying process. During the drying process, lint from the clothes will fall off and be carried by the fan into the entire airflow duct.

[0004] To avoid the above situations, many washer-dryer combos choose to install a filter device inside the drying duct to filter lint. However, with the use of the washer-dryer combo, a large amount of lint will accumulate on the filter device, which is inconvenient to clean because it is installed inside the drying duct.

[0005] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing filter devices are installed inside the drying air duct and are inconvenient to clean.

[0007] In a first aspect, the present invention provides a drying device, including a housing and a drying system. The drying system includes a drying duct and a filter device. The drying duct is provided with a first insertion port. The housing is provided with a second insertion port at a position corresponding to the first insertion port. The filter device includes a housing and a filter assembly mounted on the housing. The housing is fixedly mounted between the housing and the drying duct, and both ends of the housing are respectively connected to the first insertion port and the second insertion port. The filter assembly is movable relative to the housing along the length direction of the housing. A portion of the filter assembly extends through the first insertion port into the drying duct, and the filter assembly extends to the second insertion port.

[0008] In the preferred embodiment of the above-mentioned drying equipment, the filter assembly includes a first bracket, a second bracket mounted on the first bracket, and a filter screen mounted on the second bracket. The first bracket is slidably connected to the outer shell. The first bracket and the second bracket are distributed along the length direction of the outer shell. The outer end of the first bracket extends to the second insertion interface. The second bracket and the filter screen extend into the drying air duct through the first insertion interface. The second bracket can move relative to the first bracket along the length direction of the first bracket or the second bracket is detachably connected to the first bracket.

[0014] In the preferred embodiment of the above-mentioned drying equipment, the filter device further includes a locking pin, the locking pin being provided with a first locking structure, and the first bracket and / or the second bracket being provided with a second locking structure. When the locking pin is in the locked position, the first locking structure and the second locking structure cooperate to lock the second bracket to the first bracket. When the locking pin is in the unlocked position, the first locking structure and the second locking structure separate, so that the second bracket can be detached from the first bracket.

[0015] In the preferred embodiment of the above-mentioned drying equipment, the locking pin is installed on the first bracket or the second bracket, and the locking pin can move relative to the first bracket or the second bracket along the width direction of the first bracket or the second bracket. The first bracket or the second bracket is provided with a first limiting structure, and the locking pin is provided with a second limiting structure. The first limiting structure and the second limiting structure cooperate to prevent the locking pin from moving relative to the first bracket or the second bracket along the length direction of the first bracket or the second bracket.

[0016] In the preferred embodiment of the above-mentioned drying equipment, the first support or the second support is provided with a third limiting structure, and the locking pin is provided with a fourth limiting structure. The third limiting structure and the fourth limiting structure abut against each other to prevent the locking pin from moving toward the end face of the first support or the second support along the width direction of the first support or the second support, thereby preventing the end face of the locking pin from exceeding the end face of the first support or the second support.

[0017] In the preferred embodiment of the above-mentioned drying equipment, the first support or the second support is provided with a first receiving cavity, the locking pin is located in the first receiving cavity, the first receiving cavity is provided with an opening on the side facing the second locking structure, and the first locking structure extends through the opening to the outside of the first receiving cavity so as to cooperate with the second locking structure.

[0018] In the preferred embodiment of the above-mentioned drying equipment, a first limiting structure is provided on the inner wall of the first receiving cavity, and a second limiting structure is provided on the locking pin. The first limiting structure and the second limiting structure cooperate to prevent the locking pin from rotating relative to the first receiving cavity; and / or

[0019] The filtering device further includes an elastic reset member installed in the first receiving cavity. The two ends of the elastic reset member are respectively connected to the inner wall of the first receiving cavity and the locking pin. The locking pin can move from the unlocked position to the locked position under the action of the elastic reset member.

[0020] In the preferred embodiment of the above-mentioned drying equipment, the drying air duct includes a first drying air duct and a second drying air duct. The first drying air duct is connected to the air inlet of the fan of the drying system, and the second drying air duct is connected to the air outlet of the fan. The first insertion interface is provided in the first drying air duct.

The first drying air duct and the second drying air duct are located on the same side of the drying cylinder, and the angle between the first drying air duct and the second drying air duct is 90°. The extension direction of the filter assembly is parallel to the axial direction of the drying cylinder.

[0021] With the above technical solution, the present invention provides a first insertion interface and a second insertion interface on the drying air duct and the housing, respectively. The filter assembly extends into the drying air duct through the first insertion interface. When the filter needs to be cleaned, it can be simply pulled out, which is very convenient. In addition, the first insertion interface and the second insertion interface are connected through the housing of the filter, which makes it easier to align the front end of the filter assembly with the first insertion interface when installing the filter assembly, thus facilitating a smooth installation and improving the user experience.

[0022] Furthermore, the filter assembly of the present invention includes a first bracket and a second bracket that are slidably or detachably connected. With this arrangement, less space is required for disassembly of the filter device, thereby improving the user experience.

[0023] Furthermore, the filtering device of the present invention drives the second support to move by setting a transmission component, so that when the second support moves with the moving frame of the first support, the moving distance of the second support is greater than the moving distance of the moving frame. In this way, when the moving frame is fully pulled out, the second support is also fully pulled out, and there is no need to pull the second support separately. This saves disassembly space, disassembly steps and disassembly time, and improves the user experience.

[0024] Furthermore, the present invention sets the transmission component as a transmission group in which a gear and two racks mesh, which has a simple structure, is easy to arrange, and has reliable transmission.

[0025] Furthermore, by setting up a strip plate, the present invention provides space for the setting of the first rack and can also cooperate with the first guide groove to guide the moving frame, making more rational use of space.

[0026] Furthermore, the present invention provides a cooperating guide structure between the movable frame and the fixed frame, between the movable frame and the outer shell, between the movable frame and the second support, and between the second support and the outer shell, which makes the movement of the movable frame and the second support more stable and facilitates the disassembly and installation of the filter assembly.

[0027] Furthermore, the filter device of the present invention connects the first bracket and the second bracket by a locking pin, which facilitates the quick disassembly and installation of the first bracket and the second bracket, thereby further improving the user experience.

[0028] Furthermore, by installing the locking pin on the first or second bracket, the present invention eliminates the need to remove the locking pin from the bracket when disassembling the first or second bracket, thus avoiding the situation where the first and second brackets cannot be assembled due to the loss of the locking pin.

[0029] Furthermore, the present invention provides a third limiting structure and a fourth limiting structure that cooperate to prevent the end face of the locking pin from exceeding the end face of the bracket, thereby ensuring the smooth installation and disassembly of the first bracket and the second bracket.

Detailed Implementation

[0058] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although the embodiments described below are in conjunction with a washer-dryer combo, the technical solutions of the present invention are equally applicable to other drying equipment with drying functions, such as dryers and garment care machines.

[0059] It should be noted that in the description of this invention, terms such as "inner," "outer," "upper," "lower," "left," "right," "top," "bottom," "front," and "rear," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0060] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] Specifically, such as Figure 1 and Figure 2As shown, the washer-dryer combo of this application includes a housing 1, a drying drum 2 installed inside the housing 1, and a drying system. The drying system can blow hot air onto the drying drum 2. The drying drum 2 is the outer drum of the washer-dryer combo, and a rotatable inner drum is provided inside the outer drum. The inner drum is used to hold clothes.

[0062] For example, such as Figure 2 As shown, the drying drum 2 is horizontally arranged. The front end of the drying drum 2 is a loading and unloading port 22 for loading and unloading clothes. Near the rear end of the drying drum 2, there is an exhaust port 21, which is connected to the air inlet of the drying system. The air outlet of the drying system extends to the loading and unloading port 22 of the drying drum 2. During the drying process, the humid air in the drying drum 2 enters the drying system through the exhaust port 21, and after being condensed and heated by the drying system, it re-enters the drying drum 2 through the loading and unloading port 22 to dry the clothes in the drying drum 2.

[0063] Preferably, such as Figure 1 and Figure 2 As shown, the drying system of the present invention includes a drying air duct and a filter device 3. A first insertion interface 411 is provided on the drying air duct, and a part of the filter device 3 extends into the drying air duct through the first insertion interface 411.

[0064] The filter device 3 is used to filter the airflow in the drying duct and intercept impurities such as lint carried by the airflow. The filter device 3 is connected to the drying duct by a plug-in connection. When the filter device 3 needs to be cleaned, it can be pulled out of the drying duct and then inserted back into the drying duct through the first plug-in interface 411 after cleaning. The operation is very convenient.

[0065] Preferably, such as Figure 1 As shown, the housing 1 of the washer-dryer of the present invention is provided with a second insertion interface 11 at a position corresponding to the first insertion interface 411, the extension direction of the filter device 3 is parallel to the axial direction of the drying drum 2 of the washer-dryer, and the filter device 3 extends to the second insertion interface 11.

[0066] For example, the second insertion interface 11 is provided on the front panel of the housing 1, and when the filter device 3 needs to be cleaned, the user can directly pull out the filter device 3 from the front panel.

[0067] Preferably, such as Figure 1 and Figure 2 As shown, the drying air duct of the present invention includes a first drying air duct 41 and a second drying air duct 42. The two ends of the first drying air duct 41 are respectively connected to the exhaust port 21 on the drying cylinder 2 and the air inlet of the fan 5 of the drying system. The air outlet of the fan 5 is connected to one end of the second drying air duct 42. The other end of the second drying air duct 42 extends toward the take-up and put-out port 22 of the drying cylinder 2. The first insertion interface 411 is provided in the first drying air duct 41.

[0068] For example, such as Figure 1 and Figure 2 As shown, the first drying air duct 41 and the second drying air duct 42 are located on the same side of the drying cylinder 2. When the drying cylinder 2 is horizontally set, both the first drying air duct 41 and the second drying air duct 42 are located above the drying cylinder 2. In addition, the extension direction of the first drying air duct 41 intersects the extension direction of the second drying air duct 42. Furthermore, the extension direction of the first drying air duct 41 is perpendicular to the axial direction of the drying cylinder 2, and the extension direction of the second drying air duct 42 is parallel to the axial direction of the drying cylinder 2. That is, the first drying air duct 41 and the second drying air duct 42 are set perpendicularly, and the angle between them is 90°. In this way, the space occupied by the drying air ducts is smaller, and the layout is more optimized.

[0069] Preferably, such as Figure 2 As shown, the extension direction of the second drying air duct 42 is perpendicular to the axis of the fan 5.

[0070] The air inlet of the fan 5 is arranged along the axial direction of the fan 5, and the air outlet of the fan 5 is arranged along the radial direction of the fan 5. The first drying air duct 41 is connected to the air inlet of the fan 5 and is parallel to the axial direction of the fan 5. The second drying air duct 42 is connected to the air outlet of the fan 5 and is perpendicular to the axial direction of the fan 5. The layout is more ingenious and the space utilization is more reasonable.

[0071] Preferably, such as Figure 2 As shown, the exhaust port 21 is located on the side wall of the drying cylinder 2.

[0072] Compared to placing the exhaust port 21 on the rear wall of the drying cylinder 2, placing the exhaust port 21 on the side wall of the drying cylinder 2 makes it easier to connect the first drying air duct 41 with the exhaust port 21.

[0073] Preferably, the drying system of the present invention further includes a heat pump module (not shown in the figure), the evaporator of the heat pump module is installed in the first drying air duct 41 and located downstream of the filter device 3, and the condenser of the heat pump module is installed in the second drying air duct 42.

[0074] Among them, such as Figure 2 As shown, after the humid airflow in the drying drum 2 enters the first drying air duct 41, it is first filtered by the filter device 3, and then condensed by the evaporator. The water vapor in the humid airflow is condensed into water. After passing through the fan 5, the airflow enters the second drying air duct 42, is heated by the condenser, and then returns to the drying drum 2 to dry the clothes in the drying drum 2.

[0075] The specific structure of the filtration device will be described in detail below with reference to three preferred embodiments of the filtration device.

[0076] Example 1

[0077] The following is combined with Figures 3 to 6 A first embodiment of the filtration device of the present invention will be described in detail.

[0078] like Figures 3 to 6 As shown, the filter device 3 of this application includes a housing 33 and a filter assembly mounted on the housing 33. The filter assembly is movable relative to the housing 33 along the length direction of the housing 33.

[0079] The outer casing 33 is fixedly installed between the drying duct and the housing 1. Specifically, the outer casing 33 is fixedly installed between the first drying duct 41 and the housing 1. Both ends of the outer casing 33 are connected to the first insertion port 411 on the first drying duct 41 and the second insertion port 11 on the housing 1, respectively. A portion of the filter assembly extends through the first insertion port 411 into the drying duct, specifically into the first drying duct 41. The filter assembly extends to the second insertion port 11. When cleaning the filter device is required, only the filter assembly needs to be pulled out; there is no need to disassemble the outer casing 33 of the filter device. Furthermore, the extending direction of the outer casing 33 and the filter assembly is preferably parallel to the axial direction of the drying cylinder 2 of the drying equipment.

[0080] Preferably, such as Figures 3 to 6 As shown, the filter assembly of the present invention includes a first support 31, a second support 32 mounted on the first support 31, and a filter screen (not shown) mounted on the second support 32.

[0081] The first bracket 31 is mounted on the outer shell 33 and can move relative to the outer shell 33 along the length direction of the outer shell 33. The first bracket 31 and the second bracket 32 ​​are distributed along the length direction of the outer shell 33. The extension directions of the first bracket 31 and the second bracket 32 ​​are parallel to the axis of the drying drum 2 of the washer-dryer. The first bracket 31 extends to the second insertion interface 11. The second bracket 32 ​​and the filter screen pass through the first insertion interface 411 and extend into the drying air duct. Specifically, the second bracket 32 ​​and the filter screen pass through the first insertion interface 411 and extend into the first drying air duct 41.

[0082] It should be noted that, in practical applications, those skilled in the art can either allow the second bracket 32 ​​to extend entirely into the first drying duct 41, or allow only the portion of the second bracket 32 ​​with the filter to extend into the first drying duct 41, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention. Of course, the present invention preferably allows only a portion of the second bracket 32 ​​to extend into the first drying duct 41.

[0083] Preferably, such as Figures 3 to 6 As shown, the second support 32 of the present invention can move relative to the first support 31 along the length direction of the first support 31.

[0084] When the filter needs to be cleaned, first pull the first bracket 31 out of the housing 1. After the outer end of the second bracket 32 ​​moves to the outside of the housing 1 along with the first bracket 31, keep the first bracket 31 still and pull the second bracket 32 ​​along the first bracket 31 until the filter is pulled out. In this way, the required lateral space is smaller when disassembling the filter device 3, disassembly is more convenient, and it is easier to arrange the washer-dryer.

[0085] Preferably, such as Figures 3 to 6 As shown, the filtration device 3 of the present invention further includes a transmission assembly. The first support 31 includes a fixed frame 311 and a movable frame 312. The movable frame 312 is movable relative to the fixed frame 311 along the length direction of the fixed frame 311. The transmission assembly is disposed between the fixed frame 311, the movable frame 312 and the second support 32. The transmission assembly is configured to drive the second support 32 to move relative to the movable frame 312 along the moving direction of the movable frame 312 when the movable frame 312 moves relative to the fixed frame 311.

[0086] The fixed bracket 311 is fixedly connected to or integrally set with the outer shell 33. When the filter screen needs to be cleaned, the movable bracket 312 of the first bracket 31 is pulled, so that the movable bracket 312 moves along the length direction of the outer shell 33. During the outward movement of the movable bracket 312, the second bracket 32 ​​also moves outward with the movable bracket 312. Moreover, driven by the transmission component, the second bracket 32 ​​will also move relative to the movable bracket 312. That is to say, the movement distance of the second bracket 32 ​​is greater than the movement distance of the movable bracket 312. In this way, when the movable bracket 312 is fully pulled out, the second bracket 32 ​​is also fully pulled out, and there is no need to pull the second bracket 32 ​​separately. This saves disassembly space, disassembly steps and disassembly time, and improves the user experience.

[0087] It should be noted that the present invention does not limit the specific structural form of the transmission component. For example, the transmission component can be set as a gear and rack transmission group, or as a sprocket and chain transmission group, or as a gear belt and pulley transmission group, etc.

[0088] Preferably, such as Figures 3 to 5 As shown, the transmission assembly of the present invention includes a first rack 34, a second rack 35, and a gear 36 meshing with the first rack 34 and the second rack 35. The first rack 34 and the second rack 35 are arranged opposite to each other, and the gear 36 is located between the first rack 34 and the second rack 35. The first rack 34 is disposed on a fixed frame 311, the gear 36 is disposed on a movable frame 312, and the second rack 35 is disposed on a second support 32.

[0089] The first rack 34 and the second rack 35 extend along the moving direction of the second bracket 32. The gear 36 is rotatably mounted on the movable frame 312. The first rack 34 is located above the second rack 35. When the movable frame 312 moves relative to the fixed frame 311, since the first rack 34 on the fixed frame 311 is fixed, the gear 36 rotates along the first rack 34, which at the same time drives the second rack 35 and the second bracket 32 ​​to move, thereby achieving double the stroke of the second bracket 32.

[0090] It should be noted that those skilled in the art can change the installation positions of the first rack 34 and the gear 36 in practical applications. That is, the first rack 34 can be placed on the movable frame 312, and the gear 36 can be rotatably installed on the fixed frame 311.

[0091] Preferably, such as Figures 3 to 5 As shown, the first bracket 31 of the present invention has a fixed frame 311 with a strip plate 313, a movable frame 312 with a first guide groove 3121, a first rack 34 disposed on one side of the strip plate 313, and a first guide portion 3131 adapted to the first guide groove 3121 on the other side of the strip plate 313. The first guide portion 3131 cooperates with the first guide groove 3121 to guide the movable frame 312 when it moves.

[0092] For example, the strip plate 313 extends along the length of the fixed frame 311, the first rack 34 is disposed at the bottom of the strip plate 313, and the top of the strip plate 313 forms a first guide portion 3131. The first guide portion 3131 is located in the first guide groove 3121. During the movement of the movable frame 312 relative to the fixed frame 311, the first guide groove 3121 moves along the first guide portion 3131 on the strip plate 313 to guide the movable frame 312.

[0093] It should be noted that when the first rack 34 is located on the movable frame 312, the strip plate 313 is located on the movable frame 312, and correspondingly, the first guide groove 3121 is located on the fixed frame 311.

[0094] Preferably, such as Figures 3 to 5 As shown, the second support 32 of the present invention is provided with a second guide groove 321 extending along its length direction, and the movable frame 312 has a second guide portion 3122 adapted to the second guide groove 321. The second guide portion 3122 cooperates with the second guide groove 321 to guide the second support 32 when it moves.

[0095] For example, the second guide groove 321 is disposed near the bottom of the second bracket 32, the movable frame 312 has a plate-shaped body, the bottom of the plate-shaped body forms a second guide portion 3122, the second guide portion 3122 is located in the second guide groove 321, during the movement of the second bracket 32 ​​relative to the movable frame 312, the second guide groove 321 moves along the second guide portion 3122 at the bottom of the movable frame 312 to guide the second bracket 32.

[0096] Preferably, such as Figures 3 to 6 As shown, the outer shell 33 of the filter device 3 of the present invention is provided with a third guide groove 332 extending along its length direction, and the moving frame 312 has a third guide portion 3123 adapted to the third guide groove 332. The third guide portion 3123 cooperates with the third guide groove 332 to guide the moving frame 312 when it moves.

[0097] For example, the third guide groove 332 is disposed near the top of the housing 33, and the top of the movable frame 312 forms a third guide portion 3123. The third guide portion 3123 is located in the third guide groove 332. During the movement of the movable frame 312 relative to the housing 33, the third guide portion 3123 moves along the third guide groove 332 on the housing 33 to guide the movable frame 312.

[0098] Preferably, such as Figures 3 to 6 As shown, the outer shell 33 of the filter device 3 of the present invention is provided with a fourth guide groove 333 extending along its length direction, and the second bracket 32 ​​has a fourth guide portion 322 adapted to the fourth guide groove 333. The fourth guide portion 322 cooperates with the fourth guide groove 333 to guide the second bracket 32 ​​when it moves.

[0099] For example, the fourth guide groove 333 is disposed near the top of the housing 33, and the top of the second bracket 32 ​​forms a fourth guide portion 322, which is located in the fourth guide groove 333. During the process of the second bracket 32 ​​relative to the housing 33, the fourth guide portion 322 moves along the fourth guide groove 333 on the housing 33 to guide the second bracket 32.

[0100] Preferably, such as Figure 3 and Figure 6 As shown, a strip-shaped guide block 331 is provided inside the outer shell 33 of the present invention, a third guide groove 332 is formed in the strip-shaped guide block 331, and a fourth guide groove 333 is formed in the gap between the strip-shaped guide block 331 and the inner wall of the outer shell 33.

[0101] For example, the strip guide block 331 is located on the top of the housing 33 and is fixedly connected to or integrally formed with the housing 33. The bottom of the strip guide block 331 is recessed inward to form a third guide groove 332. There is a gap between the strip guide block 331 and the left side wall of the housing 33, which forms a fourth guide groove 333.

[0102] Example 2

[0103] The following is combined with Figures 7 to 11 A first embodiment of the filtration device of the present invention will be described in detail.

[0104] like Figure 7 and Figure 8 As shown, the filter device 3 of this application includes a housing 33 and a filter assembly mounted on the housing 33. The filter assembly is movable relative to the housing 33 along the length direction of the housing 33.

[0105] The outer casing 33 is fixedly installed between the drying duct and the housing 1. Specifically, the outer casing 33 is fixedly installed between the first drying duct 41 and the housing 1. Both ends of the outer casing 33 are connected to a first insertion port 411 on the first drying duct 41 and a second insertion port 11 on the housing 1, respectively. A portion of the filter assembly extends through the first insertion port 411 into the drying duct, specifically into the first drying duct 41. The filter assembly extends to the second insertion port 11. When cleaning the filter device is required, only the filter assembly needs to be pulled out; there is no need to disassemble the outer casing 33 of the filter device. Furthermore, the extending direction of the outer casing 33 and the filter assembly is preferably parallel to the axial direction of the drying cylinder 2 of the drying equipment.

[0106] Preferably, such as Figure 7 and Figure 8 As shown, the filter assembly of the present invention includes a first support 31, a second support 32 mounted on the first support 31, and a filter screen (not shown) mounted on the second support 32.

[0107] The first bracket 31 is mounted on the outer shell 33 and can move relative to the outer shell 33 along the length direction of the outer shell 33. The first bracket 31 and the second bracket 32 ​​are distributed along the length direction of the outer shell 33. The extension directions of the first bracket 31 and the second bracket 32 ​​are parallel to the axis of the drying drum 2 of the washer-dryer. The first bracket 31 extends to the second insertion interface 11. The second bracket 32 ​​and the filter screen pass through the first insertion interface 411 and extend into the drying air duct. Specifically, the second bracket 32 ​​and the filter screen pass through the first insertion interface 411 and extend into the first drying air duct 41.

[0108] It should be noted that, in practical applications, those skilled in the art can either allow the second bracket 32 ​​to extend entirely into the first drying duct 41, or allow only the portion of the second bracket 32 ​​with the filter to extend into the first drying duct 41, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention. Of course, the present invention preferably allows only a portion of the second bracket 32 ​​to extend into the first drying duct 41.

[0109] Preferably, such as Figures 8 to 11 As shown, the second bracket 32 ​​of the present invention is detachably connected to the first bracket 31.

[0110] When the filter needs to be cleaned, first pull the first bracket 31 out of the housing 1. After the outer end of the second bracket 32 ​​moves to the outside of the housing 1 along with the first bracket 31, separate the first bracket 31 from the second bracket 32. Then continue to pull the second bracket 32 ​​until the filter is pulled out. In this way, less lateral space is required when disassembling the filter device 3, making disassembly more convenient and facilitating the arrangement of the washer-dryer.

[0111] Preferably, such as Figures 8 to 11 As shown, the filter device 3 of the present invention further includes a locking pin 34, on which a first locking structure 341 is provided, and a second locking structure 321 is provided on the first bracket 31 and / or the second bracket 32. When the locking pin 34 is in the locked position, the first locking structure 341 and the second locking structure 321 cooperate to lock the second bracket 32 ​​to the first bracket 31. When the locking pin 34 is in the unlocked position, the first locking structure 341 and the second locking structure 321 separate, so that the second bracket 32 ​​can be detached from the first bracket 31.

[0112] The present invention locks the first bracket 31 and the second bracket 32 ​​by means of locking pin 34. When it is necessary to disassemble the two brackets, the locking pin 34 can be unlocked.

[0113] It should be noted that the present invention does not limit the specific structural form of the first locking structure 341 and the second locking structure 321. For example, the first locking structure 341 and the second locking structure 321 can be configured as a structure in which two locking hooks cooperate, or as a structure in which a locking hook cooperates with a lock opening, or as a structure in which a locking pin cooperates with a lock hole, etc.

[0114] Furthermore, it should be noted that those skilled in the art can configure the locking pin 34 as an independent component. Both the first bracket 31 and the second bracket 32 ​​are provided with a second locking structure, such as a lock hole. After aligning the lock hole on the first bracket 31 with the lock hole on the second bracket 32, the locking pin 34 is inserted into the two lock holes to lock the first bracket 31 and the second bracket 32. The part inserted into the lock hole is the first locking structure. Alternatively, the locking pin 34 can be installed on the first bracket 31 and the second locking structure can be set on the second bracket 32. Or, the locking pin 34 can be installed on the second bracket 32 ​​and the second locking structure can be set on the first bracket 31, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0115] Preferably, such as Figures 8 to 11 As shown, the locking pin 34 of the present invention is mounted on the first bracket 31. The locking pin 34 is movable relative to the first bracket 31 along the width direction of the first bracket 31. The first bracket 31 is provided with a first limiting structure 311, and the locking pin 34 is provided with a second limiting structure 342. The first limiting structure 311 and the second limiting structure 342 cooperate to prevent the locking pin 34 from moving relative to the first bracket 31 along the length direction of the first bracket 31.

[0116] For example, such as Figures 8 to 11 As shown, the width direction of the first bracket 31 is the vertical direction. The locking pin 34 is vertically installed on the first bracket 31 and can move relative to the first bracket 31 in the vertical direction. Through the cooperation of the first limiting structure 311 and the second limiting structure 342, the locking pin 34 is limited on the first bracket 31, so that the locking pin 34 cannot move relative to the first bracket 31 in the horizontal direction. The first locking structure 341 faces the right end face of the first bracket 31. The right end face of the first bracket 31 is provided with a socket 312. The second locking structure 321 is provided on the left end face of the second bracket 32. The left end of the second bracket 32 ​​passes through the socket 312 and extends into the first bracket 31. The second locking structure 321 and the first locking structure 341 are locked together.

[0117] That is, the locking pin 34 is mounted on the first bracket 31, and correspondingly, the second locking structure 321 is disposed on the second bracket 32. Of course, the locking pin 34 can also be mounted on the second bracket 32, and the second locking structure 321 can be disposed on the first bracket 31. In this case, the first limiting structure 311 is disposed on the second bracket 32, and the locking pin 34 can move relative to the second bracket 32 ​​along the width direction of the second bracket 32. The first limiting structure 311 and the second limiting structure 342 cooperate to prevent the locking pin 34 from moving relative to the second bracket 32 ​​along the length direction of the second bracket 32.

[0118] It should be noted that the present invention does not limit the specific structural form of the first limiting structure 311 and the second limiting structure 342. For example, it can be configured as a structure in which the limiting groove and the limiting rib cooperate, or as a structure in which the limiting groove and the limiting block cooperate, or as a structure in which the limiting hole and the limiting plate cooperate, etc.

[0119] Preferably, such as Figures 8 to 11 As shown, the first limiting structure 311 is a strip-shaped limiting groove, and the second limiting structure 342 is a strip-shaped limiting rib adapted to the strip-shaped limiting groove, with the strip-shaped limiting rib located inside the strip-shaped limiting groove.

[0120] For example, such as Figures 8 to 11 As shown, the strip-shaped limiting groove extends vertically, and the strip-shaped limiting rib extends along the axis of the locking pin 34. There are two strip-shaped limiting grooves, which are arranged opposite to each other. It should be noted that, in order to make it easier to see the cooperation between the locking pin 34 and the second bracket 32, Figure 8 and Figure 10 Only a part of the first bracket is shown in the figure. There is also a cover plate that together with the bracket structure shown in the figure to form the first bracket. Another strip-shaped limiting groove is set on the inner wall of the cover plate. The locking pin 34 is located between the two strip-shaped limiting grooves. There are also two strip-shaped limiting ribs, which are located on both sides of the locking pin 34. The two strip-shaped limiting ribs are inserted into the corresponding strip-shaped limiting grooves to prevent the locking pin 34 from moving relative to the first bracket 31 along the length direction of the first bracket 31.

[0121] It should be noted that, in practical applications, those skilled in the art may also set the first limiting structure 311 as a strip-shaped limiting rib, and correspondingly set the second limiting structure 342 as a strip-shaped limiting groove.

[0122] Preferably, such as Figures 8 to 11 As shown, the first locking structure 341 is a locking hook, and the second locking structure 321 is a locking port adapted to the locking hook, with a portion of the locking hook being able to be inserted into the locking port.

[0123] For example, such as Figures 8 to 11 As shown, the locking pin 34 is vertically mounted on the first bracket 31. Two locking hooks are positioned upwards on the locking pin 34 and spaced apart along its axis. The second bracket 32 ​​has two corresponding locking slots, with the locking hooks located below them. When the locking hooks are inserted into the locking slots, the first bracket 31 and the second bracket 32 ​​are locked together. To disassemble the two brackets, the locking pin 34 is pressed downwards to separate the locking hooks from the locking slots. It should be noted that only one locking hook and one locking slot can also be used.

[0124] Preferably, such as Figure 8 and Figure 9As shown, the filter device 3 of the present invention further includes an elastic reset member 35 mounted on the first bracket 31. The two ends of the elastic reset member 35 are respectively connected to the first bracket 31 and the locking pin 34. Under the action of the elastic reset member 35, the locking pin 34 can move from the unlocked position to the locked position.

[0125] For example, the elastic reset member 35 is arranged vertically and located between the locking pin 34 and the inner bottom wall of the first bracket 31. When the locking pin 34 is pressed down, the elastic reset member 35 is compressed. When the locking pin 34 is released, the elastic reset member 35 can push the locking pin 34 up, so that the locking pin 34 moves from the unlocked position to the locked position.

[0126] It should be noted that when the locking pin 34 is installed on the second bracket 32, the elastic reset member 35 is installed on the second bracket 32, and the two ends of the elastic reset member 35 are connected to the second bracket 32 ​​and the locking pin 34 respectively.

[0127] Preferably, the locking pin 34 is further provided with a receiving cavity (not shown in the figure), and a part of the elastic reset member 35 is located in the receiving cavity.

[0128] For example, such as Figure 9 As shown, the locking pin 34 is vertically arranged, the receiving cavity extends along the axis of the locking pin 34, and the receiving cavity extends to the bottom end of the locking pin 34. The elastic reset member 35 is inserted into the receiving cavity from the bottom end of the locking pin 34.

[0129] It should be noted that the present invention does not limit the specific structural form of the elastic reset member 35. For example, the elastic reset member 35 can be set as a spring or a rubber column, etc. Of course, the present invention preferably sets the elastic reset member 35 as a spring.

[0130] Preferably, such as Figures 8 to 11 As shown, the first bracket 31 of the present invention is provided with a third limiting structure 313, and the locking pin 34 is provided with a fourth limiting structure 343. The third limiting structure 313 and the fourth limiting structure 343 abut against each other to prevent the locking pin 34 from moving toward the end face of the first bracket 31 along the width direction of the first bracket 31, thereby preventing the end face of the locking pin 34 from exceeding the end face of the first bracket 31.

[0131] For example, the locking pin 34 is installed into the first bracket 31 from the upper end face of the first bracket 31. Pressing the locking pin 34 downward can unlock the device. When the locking pin 34 moves upward to the locking position, the fourth limiting structure 343 abuts against the third limiting structure 313 to prevent the locking pin 34 from moving upward further, so as to prevent the upper end face of the locking pin 34 from exceeding the upper end face of the first bracket 31. Of course, it is preferable to make the upper end face of the locking pin 34 flush with the upper end face of the first bracket 31.

[0132] It should be noted that when the locking pin 34 is installed on the second bracket 32, the third limiting structure 313 is provided on the second bracket 32. The third limiting structure 313 and the fourth limiting structure 343 abut against each other to prevent the locking pin 34 from moving toward the end face of the second bracket 32 ​​along the width direction of the second bracket 32, thereby preventing the end face of the locking pin 34 from exceeding the end face of the second bracket 32.

[0133] It should be noted that the present invention does not limit the specific structural form of the third limiting structure 313 and the fourth limiting structure 343. For example, they can be configured as a structure in which two limiting blocks cooperate, or as a structure in which two limiting posts cooperate, or as a structure in which two limiting plates cooperate, etc.

[0134] Preferably, such as Figures 8 to 11 As shown, the third limiting structure 313 is a limiting plate, and the fourth limiting structure 343 is a limiting block.

[0135] Of course, the fourth limiting structure 343 can also be set as a limiting plate, and the third limiting structure 313 can be set as a limiting block.

[0136] Example 3

[0137] The following is combined with Figures 12 to 16 A first embodiment of the filtration device of the present invention will be described in detail.

[0138] like Figure 12 and Figure 13 As shown, the filter device 3 of this application includes a housing 33 and a filter assembly mounted on the housing 33. The filter assembly is movable relative to the housing 33 along the length direction of the housing 33.

[0139] The outer casing 33 is fixedly installed between the drying duct and the housing 1. Specifically, the outer casing 33 is fixedly installed between the first drying duct 41 and the housing 1. Both ends of the outer casing 33 are connected to the first insertion port 411 on the first drying duct 41 and the second insertion port 11 on the housing 1, respectively. A portion of the filter assembly extends through the first insertion port 411 into the drying duct, specifically into the first drying duct 41. The filter assembly extends to the second insertion port 11. When cleaning the filter device is required, only the filter assembly needs to be pulled out; there is no need to disassemble the outer casing 33 of the filter device. Furthermore, the extending direction of the outer casing 33 and the filter assembly is preferably parallel to the axial direction of the drying cylinder 2 of the drying equipment.

[0140] Preferably, such as Figure 12 and Figure 13 As shown, the filter assembly of the present invention includes a first support 31, a second support 32 mounted on the first support 31, and a filter screen (not shown) mounted on the second support 32.

[0141] The first bracket 31 is mounted on the outer shell 33 and can move relative to the outer shell 33 along the length direction of the outer shell 33. The first bracket 31 and the second bracket 32 ​​are distributed along the length direction of the outer shell 33. The extension direction of the first bracket 31, the second bracket 32 ​​and the outer shell 33 is parallel to the axis direction of the drying drum 2 of the washer-dryer. The first bracket 31 extends to the second insertion interface 11. The second bracket 32 ​​and the filter screen extend into the drying air duct through the first insertion interface 411. Specifically, the second bracket 32 ​​and the filter screen extend into the first drying air duct 41 through the first insertion interface 411.

[0142] It should be noted that, in practical applications, those skilled in the art can either allow the second bracket 32 ​​to extend entirely into the first drying duct 41, or allow only the portion of the second bracket 32 ​​with the filter to extend into the first drying duct 41, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention. Of course, the present invention preferably allows only a portion of the second bracket 32 ​​to extend into the first drying duct 41.

[0143] Furthermore, it should be noted that, in practical applications, those skilled in the art can allow the entire filter screen to extend into the first drying air duct 41, or only a portion of the filter screen to extend into the first drying air duct 41, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention. Of course, the present invention preferably allows the entire filter screen to extend into the first drying air duct 41.

[0144] In a first preferred embodiment, the second support 32 of the present invention is movable relative to the first support 31 along the length direction of the first support 31.

[0145] When the filter needs to be cleaned, first pull the first bracket 31 out of the housing 1. After the outer end of the second bracket 32 ​​moves to the outside of the housing 1 along with the first bracket 31, keep the first bracket 31 still and pull the second bracket 32 ​​along the first bracket 31 until the filter is pulled out. In this way, the required lateral space is smaller when disassembling the filter device 3, disassembly is more convenient, and it is easier to arrange the washer-dryer.

[0146] In a second preferred embodiment, the second bracket 32 ​​of the present invention is detachably connected to the first bracket 31.

[0147] When the filter needs to be cleaned, first pull the first bracket 31 out of the housing 1. After the outer end of the second bracket 32 ​​moves to the outside of the housing 1 along with the first bracket 31, separate the first bracket 31 from the second bracket 32. Then continue to pull the second bracket 32 ​​until the filter is pulled out. In this way, less lateral space is required when disassembling the filter device 3, making disassembly more convenient and facilitating the arrangement of the washer-dryer.

[0148] Preferably, such as Figures 13 to 16 As shown, the filter device 3 of the present invention further includes a locking pin 34, on which a first locking structure 341 is provided, and a second locking structure 323 is provided on the first bracket 31 and / or the second bracket 32. When the locking pin 34 is in the locked position, the first locking structure 341 and the second locking structure 323 cooperate to lock the second bracket 32 ​​to the first bracket 31. When the locking pin 34 is in the unlocked position, the first locking structure 341 and the second locking structure 323 separate, so that the second bracket 32 ​​can be detached from the first bracket 31.

[0149] The present invention locks the first bracket 31 and the second bracket 32 ​​by means of locking pin 34. When it is necessary to disassemble the two brackets, the locking pin 34 can be unlocked.

[0150] It should be noted that the present invention does not limit the specific structural form of the first locking structure 341 and the second locking structure 323. For example, the first locking structure 341 and the second locking structure 323 can be configured as a structure in which two locking hooks cooperate, or as a structure in which a locking hook cooperates with a lock opening, or as a structure in which a locking pin cooperates with a lock hole, etc.

[0151] Furthermore, it should be noted that those skilled in the art can configure the locking pin 34 as an independent component. Both the first bracket 31 and the second bracket 32 ​​are provided with a second locking structure, such as a lock hole. After aligning the lock hole on the first bracket 31 with the lock hole on the second bracket 32, the locking pin 34 is inserted into the two lock holes to lock the first bracket 31 and the second bracket 32. The part inserted into the lock hole is the first locking structure. Alternatively, the locking pin 34 can be installed on the first bracket 31 and the second locking structure can be set on the second bracket 32. Or, the locking pin 34 can be installed on the second bracket 32 ​​and the second locking structure can be set on the first bracket 31, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be limited to the protection scope of the present invention.

[0152] Preferably, such as Figures 13 to 16 As shown, the first bracket 31 is provided with a first receiving cavity 311, the locking pin 34 is located in the first receiving cavity 311, the first receiving cavity 311 is provided with an opening 312 on the side facing the second locking structure 323, and the first locking structure 341 extends through the opening 312 to the outside of the first receiving cavity 311 so as to cooperate with the second locking structure 323.

[0153] For example, such as Figures 13 to 16As shown, the first receiving cavity 311 is located near the right end of the first bracket 31, the locking pin 34 is located inside the first receiving cavity 311, the first locking structure 341 faces the right end face of the first bracket 31, the right end face of the first bracket 31 is provided with an insertion port 314, the second locking structure 323 is located on the left end face of the second bracket 32, the left end of the second bracket 32 ​​passes through the insertion port 314 and extends into the first bracket 31, and the second locking structure 323 and the first locking structure 341 are locked together.

[0154] In other words, the locking pin 34 is installed on the first bracket 31, and correspondingly, the second locking structure 323 is provided on the second bracket 32. Of course, the locking pin 34 can also be installed on the second bracket 32, the first receiving cavity 311 is provided on the second bracket 32, and the second locking structure 323 is provided on the first bracket 31.

[0155] Preferably, such as Figures 13 to 16 As shown, the first locking structure 341 is a first locking hook, and the second locking structure 323 is a second locking hook that is adapted to the first locking hook.

[0156] For example, such as Figures 13 to 16 As shown, the first receiving cavity 311 is disposed on the top surface of the first bracket 31. The first receiving cavity 311 is disposed vertically. The top end of the locking pin 34 extends from the top of the first receiving cavity 311, that is, the top end of the locking pin 34 is slightly higher than the top surface of the first bracket 31, which facilitates pressing the locking pin 34 downward. The first locking hook disposed on the locking pin 34 is disposed upward, and the second locking hook disposed on the second bracket 32 ​​is disposed downward. The first locking hook is located below the second locking hook. When the first locking hook and the second locking hook are hooked together, the first bracket 31 and the second bracket 32 ​​are locked. When it is necessary to disassemble the two brackets, the locking pin 34 is pressed downward to separate the first locking hook and the second locking hook. The opening 312 communicating with the first receiving cavity 311 is disposed vertically, allowing the first locking hook to move up and down.

[0157] Preferably, such as Figures 13 to 15 As shown, the filter device 3 of the present invention further includes an elastic reset member 35 installed in the first receiving cavity 311. The two ends of the elastic reset member 35 are respectively connected to the inner wall of the first receiving cavity 311 and the locking pin 34. Under the action of the elastic reset member 35, the locking pin 34 can move from the unlocked position to the locked position.

[0158] For example, the elastic reset member 35 is arranged vertically and located between the locking pin 34 and the inner bottom wall of the first receiving cavity 311. When the locking pin 34 is pressed down, the elastic reset member 35 is compressed. When the locking pin 34 is released, the elastic reset member 35 can push the locking pin 34 up, so that the locking pin 34 moves from the unlocked position to the locked position.

[0159] Preferably, the locking pin 34 is further provided with a second receiving cavity (not shown in the figure), and a part of the elastic reset member 35 is located in the second receiving cavity.

[0160] For example, such as Figure 14 As shown, the locking pin 34 is vertically arranged, the second receiving cavity extends along the axis of the locking pin 34, and the second receiving cavity extends to the bottom end of the locking pin 34. The elastic reset member 35 is inserted into the second receiving cavity from the bottom end of the locking pin 34.

[0161] It should be noted that the present invention does not limit the specific structural form of the elastic reset member 35. For example, the elastic reset member 35 can be set as a spring or a rubber column, etc. Of course, the present invention preferably sets the elastic reset member 35 as a spring.

[0162] Preferably, such as Figures 14 to 16 As shown, a first limiting structure 313 is provided on the inner wall of the first receiving cavity 311, and a second limiting structure 342 is provided on the locking pin 34.
