An exhaust port 21 is provided near the rear end of the drying drum 2, and the exhaust port 21 is connected with the air inlet end of the drying system. The air outlet end of the drying system extends to the loading and unloading port 22 of the drying drum 2. During the execution of the drying program, the humid air in the drying drum 2 enters the drying system from the exhaust port 21, and after condensation and heating by the drying system, re-enters the drying drum 2 from the loading and unloading port 22 to dry the clothes in the drying drum 2.

[0060] Preferably, if Figure 1 and Figure 2 As shown, the drying system of the present invention comprises a drying air duct and a filter device 3. A first plug 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 plug interface 411.

[0061] Among them, the filter device 3 is used to filter the airflow in the drying air duct and intercept impurities such as lint carried by the airflow. By connecting the filter device 3 to the drying air duct by plugging, when the filter device 3 needs to be cleaned, the filter device 3 can be pulled out of the drying air duct, and then inserted into the drying air duct from the first plug interface 411 after cleaning, which is very convenient to operate.

[0062] Preferably, if Figure 1 As shown, the housing 1 of the washer-dryer of the present invention is provided with a second plug interface 11 at a position corresponding to the first plug 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 plug interface 11 .

[0063] Exemplarily, the second plug interface 11 is disposed 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.

[0064] Preferably, if Figure 1 and Figure 2 As shown, the drying air duct of the utility model 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 drum 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 loading and unloading port 22 of the drying drum 2. The first plug interface 411 is provided on the first drying air duct 41.

[0065] For example, Figure 1 and Figure 2 As shown, the first drying air duct 41 and the second drying air duct 42 are both located above the drying drum 2 and are arranged horizontally, the extension direction of the first drying air duct 41 is perpendicular to the axial direction of the drying drum 2, and the extension direction of the second drying air duct 42 is parallel to the axial direction of the drying drum 2, that is, the first drying air duct 41 and the second drying air duct 42 are arranged vertically, and the angle between the two is 90°. In this way, the drying air duct occupies less space and the layout is more optimized.

[0066] Preferably, if Figure 1 and Figure 3 As shown, the filter device 3 of the present application includes a housing 33 and a filter assembly installed on the housing 33 , and the filter assembly can move relative to the housing 33 along the length direction of the housing 33 .

[0067] The housing 33 is fixedly installed between the drying air duct and the housing 1, specifically, the housing 33 is fixedly installed between the first drying air duct 41 and the housing 1, and the two ends of the housing 33 are respectively connected with the first plug port 411 on the first drying air duct 41 and the second plug port 11 on the housing 1, and a part of the filter assembly extends into the drying air duct through the first plug port 411, specifically into the first drying air duct 41, and the filter assembly extends to the second plug port 11. When the filter device needs to be cleaned, it is only necessary to pull out the filter assembly without disassembling the housing 33 of the filter device. In addition, the extension direction of the housing 33 and the filter assembly is preferably parallel to the axial direction of the drying drum 2 of the drying device.

[0068] It should be noted that the housing 33 is not mandatory, and those skilled in the art may also cancel the housing 33 according to actual conditions in actual applications.

[0069] Preferably, if Figure 3 and Figure 4 As shown, the filter assembly of the present invention includes a first bracket 31 , a second bracket 32 ​​installed on the first bracket 31 , and a filter screen (not shown in the figure) installed on the second bracket 32 ​​.

[0070] Among them, the first bracket 31 is installed on the shell 33 and can move relative to the shell 33 along the length direction of the shell 33. The first bracket 31 and the second bracket 32 ​​are distributed along the length direction of the shell 33. The extension directions of the first bracket 31 and the second bracket 32 ​​are parallel to the axial direction of the drying drum 2 of the washer-dryer. The first bracket 31 extends to the second plug interface 11, and the second bracket 32 ​​and the filter screen pass through the first plug interface 411 and extend into the drying air duct. Specifically, the second bracket 32 ​​and the filter screen pass through the first plug interface 411 and extend into the first drying air duct 41.

[0071] It should be noted that, in actual application, those skilled in the art can make the second bracket 32 ​​extend completely into the first drying air duct 41, or only make the second bracket 32 ​​with the filter installed extend into the first drying air duct 41, etc. Such flexible adjustment and change do not deviate from the principle and scope of the utility model and should be limited within the protection scope of the utility model. Of course, the utility model preferably makes only a part of the second bracket 32 ​​extend into the first drying air duct 41.

[0072] In addition, it should be noted that, in actual application, those skilled in the art can extend the entire filter screen into the first drying air duct 41, or only extend a portion of the filter screen into the first drying air duct 41, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be limited within the protection scope of the present invention. Of course, the present invention preferably extends the entire filter screen into the first drying air duct 41.

[0073] Preferably, if Figures 4 to 7 As shown, the second bracket 32 ​​of the present invention is detachably connected to the first bracket 31 .

[0074] When the filter needs to be cleaned, first pull the first bracket 31 out of the box body 1. When the outer end of the second bracket 32 ​​moves to the outside of the box body 1 with the first bracket 31, disassemble the first bracket 31 and the second bracket 32, and then continue to pull the second bracket 32 ​​until the filter is pulled out. In this way, when disassembling the filter device 3, the required lateral space is smaller, disassembly is more convenient, and it is easy to arrange the washer-dryer.

[0075] It should be noted that, in actual application, those skilled in the art may also set the second bracket 32 ​​to be movable relative to the first bracket 31 along the length direction of the first bracket 31. In this way, when the filter needs to be cleaned, the first bracket 31 is first pulled out of the box body 1, and when the outer end of the second bracket 32 ​​moves to the outside of the box body 1 along with the first bracket 31, the first bracket 31 is kept stationary, and the second bracket 32 ​​is pulled to move along the first bracket 31 until the filter is pulled out. In this way, when disassembling the filter device 3, the required lateral space is smaller, the disassembly is more convenient, and it is convenient to arrange the washer-dryer.

[0076] Preferably, if Figures 4 to 7 As shown, the filter device 3 of the utility model also includes a locking pin 34, a first locking structure 341 is provided on the locking pin 34, 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 locking position, the first locking structure 341 cooperates with the second locking structure 321 to lock the second bracket 32 ​​to the first bracket 31. When the locking pin 34 is in the unlocking position, the first locking structure 341 is separated from the second locking structure 321 so that the second bracket 32 ​​can be removed from the first bracket 31.

[0077] The utility model locks the first bracket 31 and the second bracket 32 ​​through the locking pin 34. When the two brackets need to be disassembled, the locking pin 34 can be unlocked.

[0078] It should be noted that the utility model 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 set as a structure in which two lock hooks cooperate with each other, or as a structure in which a lock hook and a lock mouth cooperate with each other, or as a structure in which a lock column and a lock hole cooperate with each other, and so on.

[0079] In addition, it should be noted that a person skilled in the art may set the locking pin 34 as an independent component, and both the first bracket 31 and the second bracket 32 ​​are provided with a second locking structure, such as a locking hole. After the locking hole on the first bracket 31 is aligned with the locking hole on the second bracket 32, the locking pin 34 is inserted into the two locking holes to lock the first bracket 31 and the second bracket 32, and the portion inserted into the locking hole is the first locking structure; alternatively, the locking pin 34 may be installed on the first bracket 31, and the second locking structure may be set on the second bracket 32; alternatively, the locking pin 34 may be installed on the second bracket 32, and the second locking structure may be set on the first bracket 31, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the utility model, and should be limited within the protection scope of the utility model.

[0080] Preferably, if Figures 4 to 7As shown, the locking pin 34 of the utility model is installed on the first bracket 31, and the locking pin 34 can move 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 cooperates with the second limiting structure 342 to prevent the locking pin 34 from moving relative to the first bracket 31 along the length direction of the first bracket 31.

[0081] For example, Figures 4 to 7 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, and 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 surface of the first bracket 31, and the right end surface of the first bracket 31 is provided with a socket 312, the second locking structure 321 is arranged on the left end surface 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, and the second locking structure 321 and the first locking structure 341 are locked with each other.

[0082] 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 cooperates with the second limiting structure 342 to prevent the locking pin 34 from moving relative to the second bracket 32 ​​along the length direction of the second bracket 32.

[0083] It should be noted that the utility model does not limit the specific structural form of the first limiting structure 311 and the second limiting structure 342. For example, it can be set to a structure in which a limiting groove cooperates with a limiting rib, or a structure in which a limiting groove cooperates with a limiting block, or a structure in which a limiting hole cooperates with a limiting plate, and so on.

[0084] Preferably, if Figures 4 to 7 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 matched with the strip-shaped limiting groove, and the strip-shaped limiting rib is located in the strip-shaped limiting groove.

[0085] For example, Figures 4 to 7As shown, the strip-shaped limit groove extends in the vertical direction, the strip-shaped limit rib extends in the axial direction of the lock pin 34, the number of the strip-shaped limit grooves is two, and the two strip-shaped limit grooves are arranged opposite to each other. It should be noted that in order to facilitate the cooperation between the lock pin 34 and the second bracket 32, Figure 4 and Figure 6 Only a part of the first bracket is shown in the figure, and there is also a first bracket composed of a cover plate and the bracket structure shown in the figure, another strip limit groove is set on the inner wall of the cover plate, the locking pin 34 is located between the two strip limit grooves, the number of strip limit ribs is also two, which are respectively located on both sides of the locking pin 34, and the two strip limit ribs are respectively inserted into the corresponding strip limit grooves to prevent the locking pin 34 from moving relative to the first bracket 31 along the length direction of the first bracket 31.

[0086] 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.

[0087] Preferably, if Figures 4 to 7 As shown, the first locking structure 341 is a locking hook, and the second locking structure 321 is a locking opening matched with the locking hook, and a part of the locking hook can be inserted into the locking opening.

[0088] For example, Figures 4 to 7 As shown, the lock pin 34 is vertically mounted on the first bracket 31, and the lock hook on the lock pin 34 is arranged upward. There are two lock hooks and they are spaced apart along the axis direction of the lock pin 34. The second bracket 32 ​​is correspondingly provided with two lock ports, and the lock hooks are located below the lock ports. When the lock hooks are inserted into the lock ports, the first bracket 31 and the second bracket 32 ​​can be locked. When the two brackets need to be disassembled, the lock pin 34 is pressed downward to separate the lock hook from the lock port. It should be noted that only one lock hook can be provided to cooperate with the lock port.

[0089] Preferably, if Figure 4 and Figure 5 As shown, the filter device 3 of the utility model also includes an elastic reset member 35 installed on the first bracket 31, and the two ends of the elastic reset member 35 are respectively connected to the first bracket 31 and the locking pin 34. The locking pin 34 can move from the unlocking position to the locking position under the action of the elastic reset member 35.

[0090] Exemplarily, the elastic reset member 35 is arranged in the vertical direction and is located between the locking pin 34 and the inner bottom wall of the first bracket 31. When the locking pin 34 is pressed downward, the elastic reset member 35 is compressed. When the locking pin 34 is released, the elastic reset member 35 can push up the locking pin 34, so that the locking pin 34 moves from the unlocking position to the locking position.

[0091] It should be noted that, when the locking pin 34 is installed on the second bracket 32 ​​, the elastic return member 35 is installed on the second bracket 32 ​​, and two ends of the elastic return member 35 are respectively connected to the second bracket 32 ​​and the locking pin 34 .

[0092] 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.

[0093] For example, Figure 5 As shown, the locking pin 34 is vertically arranged, the accommodating cavity extends along the axis of the locking pin 34 , the accommodating cavity extends to the bottom end of the locking pin 34 , and the elastic reset member 35 is inserted into the accommodating cavity from the bottom end of the locking pin 34 .

[0094] 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.

[0095] Preferably, if Figures 4 to 7 As shown, the first bracket 31 of the utility model 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 along the width direction of the first bracket 31 toward the end face 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.

[0096] Exemplarily, the locking pin 34 is installed into the first bracket 31 from the upper end surface of the first bracket 31. Pressing the locking pin 34 downward can achieve unlocking. When the locking pin 34 moves upward to the locking position, the fourth limiting structure 343 abuts against the third limiting structure 313 to block the locking pin 34 from continuing to move upward, so as to prevent the upper end surface of the locking pin 34 from exceeding the upper end surface of the first bracket 31. Of course, it is preferred to make the upper end surface of the locking pin 34 flush with the upper end surface of the first bracket 31.

[0097] It should be noted that, when the locking pin 34 is installed on the second bracket 32, the third limiting structure 313 is arranged on the second bracket 32, and the third limiting structure 313 and the fourth limiting structure 343 are abutted against each other to prevent the locking pin 34 from moving along the width direction of the second bracket 32 ​​toward the end face 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.

[0098] It should be noted that the utility model does not limit the specific structural form of the third limiting structure 313 and the fourth limiting structure 343. For example, it can be set as a structure in which two limiting blocks cooperate with each other, or set as a structure in which two limiting columns cooperate with each other, or set as a structure in which two limiting plates cooperate with each other, and so on.

[0099] Preferably, if Figures 4 to 7 As shown, the third limiting structure 313 is a limiting plate, and the fourth limiting structure 343 is a limiting block.

[0100] Of course, the fourth limiting structure 343 may also be set as a limiting plate, and the third limiting structure 313 may be set as a limiting block.

[0101] Preferably, if Figures 8 to 11 As shown, the filter device 3 of the utility model also includes a first sealing member 36 and a second sealing member 37, both of which are installed at the first plug interface 411, and the first sealing member 36 and the second sealing member 37 are spaced apart along the insertion direction of the filter assembly, the first sealing member 36 and the second sealing member 37 are both annular, and the first sealing member 36 and the second sealing member 37 are both arranged around the filter assembly, and the inner wall of the first sealing member 36 and / or the inner wall of the second sealing member 37 are sealed and fitted with the filter assembly.

[0102] By installing the first sealing member 36 and the second sealing member 37 at the first plug-in port 411, air leakage at the first plug-in port 411 can be avoided to ensure the drying efficiency of the drying device, and since the first sealing member 36 and the second sealing member 37 are spaced apart along the insertion direction of the filter assembly, double sealing can be achieved, and the sealing effect is better. The insertion direction of the filter assembly is the length direction of the filter assembly.

[0103] It should be noted that, those skilled in the art may install both the first sealing component 36 and the second sealing component 37 inside the first drying air duct 41, or may install the first sealing component 36 inside the first drying air duct 41 and the second sealing component 37 outside the first drying air duct 41, and so on. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and should be limited within the protection scope of the present utility model.

[0104] In addition, it should be noted that the filter assembly includes a first bracket 31 and a second bracket 32. In actual applications, those skilled in the art may make the inner wall of the first sealing component 36 and / or the inner wall of the second sealing component 37 seal with only one of the first bracket 31 and the second bracket 32, or may make the inner wall of the first sealing component 36 and / or the inner wall of the second sealing component 37 seal with both the first bracket 31 and the second bracket 32. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be limited within the scope of protection of the present invention.

[0105] The technical solution of the present invention will be further described below by taking the sealing fit with the second bracket 32 ​​of the filter assembly as an example.

[0106] Preferably, if Figures 10 to 14 As shown, the first sealing member 36 includes an integrally formed skeleton 362 and an elastic sealing body 361 . The elastic sealing body 361 wraps the skeleton 362 , and the inner wall of the elastic sealing body 361 is sealed to the filter assembly, specifically to the second bracket 32 ​​.

[0107] By arranging the skeleton 362 inside the elastic sealing body 361, the skeleton 362 can play a supporting role, so that the first sealing member 36 has better structural strength, thereby improving the sealing stability of the first sealing member 36. Among them, the skeleton 362 is preferably made of plastic material, and the elastic sealing body 361 is preferably made of rubber material, and the two are integrally molded by double-material injection molding process.

[0108] Preferably, if Figures 11 to 13 As shown, the inner bottom wall of the first sealing component 36 of the utility model is provided with a strip-shaped sealing protrusion 363 , and the strip-shaped sealing protrusion 363 is sealingly fitted with the bottom of the filter assembly, specifically, with the bottom of the second bracket 32 ​​.

[0109] The strip-shaped sealing protrusion 363 is disposed on the inner bottom wall of the elastic sealing body 361 of the first sealing component 36 , and protrudes vertically toward the inner top wall of the elastic sealing body 361 . The top of the strip-shaped sealing protrusion 363 is sealed against the bottom of the second bracket 32 ​​.

[0110] Preferably, if Figures 11 to 13 As shown, the cross section of the strip-shaped sealing protrusion 363 on the first sealing component 36 of the utility model is trapezoidal, and the side of the strip-shaped sealing protrusion 363 with a smaller thickness is sealed and fitted with the second bracket 32 ​​of the filter assembly.

[0111] Among them, the thickness of the strip sealing protrusion 363 gradually decreases upward in the vertical direction, that is, the thickness of the bottom of the strip sealing protrusion 363 is greater than the thickness of the top of the strip sealing protrusion 363. By making the bottom of the strip sealing protrusion 363 have a larger thickness, the strip sealing protrusion 363 has better stability, and by making the top of the strip sealing protrusion 363 have a smaller thickness, the strip sealing protrusion 363 is easier to seal and fit with the second bracket 32.

[0112] Preferably, if Figures 8 to 14 As shown, a strip sealing lip 364 is provided on the inner wall of the first sealing component 36 , and the strip sealing lip 364 is sealingly fitted with the top and the side of the second bracket 32 ​​of the filter assembly.

[0113] The strip sealing lip 364 is disposed on the inner wall of the elastic sealing body 361 of the first sealing component 36 , and the side of the strip sealing lip 364 away from the elastic sealing body 361 is sealed against the top and side of the second bracket 32 ​​.

[0114] Preferably, if Figures 11 to 13 As shown, the ratio of the thickness of the root of the strip-shaped sealing protrusion 363 to the thickness of the root of the strip-shaped sealing lip 364 is not less than 2. The root refers to the portion connected to the elastic sealing body 361 of the first sealing member 36 .

[0115] That is to say, the size of the strip-shaped sealing protrusion 363 is larger, so that the strip-shaped sealing protrusion 363 can play a better supporting role.

[0116] Preferably, if Figures 11 to 13 As shown, two ends of the strip-shaped sealing lip 364 are respectively connected to two ends of the strip-shaped sealing protrusion 363 .

[0117] That is to say, the strip-shaped sealing lip 364 is connected end to end with the strip-shaped sealing protrusion 363 to form a ring, which has a better sealing effect.

[0118] Preferably, if Figures 11 to 14 As shown, there are multiple strip-shaped sealing lips 364 , and the multiple strip-shaped sealing lips 364 are distributed at intervals along the thickness direction of the first sealing member 36 .

[0119] By providing a plurality of spaced strip sealing lips 364, the sealing effect of the first sealing member 36 can be improved. For example, there are two strip sealing lips 364, and both ends of the two strip sealing lips 364 are connected to both ends of the strip sealing protrusion 363 respectively.

[0120] Preferably, if Figures 8 to 14 As shown, a receiving groove 412 is provided in the drying air duct, the first sealing member 36 is located in the receiving groove 412 , and a protruding structure 365 is provided on the outer wall of the first sealing member 36 , and the protruding structure 365 is tightly pressed against the inner wall of the receiving groove 412 .

[0121] Among them, the accommodating groove 412 is arranged inside the first drying air duct 41, and the protruding structure 365 is arranged on the outer wall of the elastic sealing body 361 of the first sealing component 36. The protruding structure 365 is tightly pressed against the inner wall of the accommodating groove 412, thereby restricting the first sealing component 36 in the accommodating groove 412.

[0122] Exemplarily, the protruding structure 365 includes two annular convex ribs, and the two annular convex ribs are respectively arranged on two outer side walls distributed in the thickness direction of the first sealing member 36 .

[0123] It should be noted that the protrusion structure 365 is not limited to the above-mentioned annular rib, for example, it can also be set as a point-shaped protrusion, etc.

[0124] Preferably, if Figures 8 to 10 As shown, an annular groove 413 is provided on the outer wall of the drying air duct of the present invention. The annular groove 413 is arranged around the first plug port 411. The second sealing member 37 is located in the annular groove 413, and the housing 33 presses the second sealing member 37 tightly.

[0125] Among them, the annular groove 413 is arranged on the outer wall of the first drying air duct 41, and the second sealing component 37 is an annular sealing ring, which is just located in the annular groove 413 and is pressed by the outer shell 33 of the filter device 3, so that the annular sealing ring is confined between the first drying air duct 41 and the outer shell 33 of the filter device 3, forming a second sealing defense line.

[0126] It should be noted that the second sealing member 37 is not limited to the annular sealing ring mentioned above, for example, it can also be set as an annular sealing gasket and the like.
