For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] Specifically, Figure 1 and Figure 2 As shown, the washer-dryer of the present application includes a housing 1, a drying drum 2 installed in the housing 1, and a drying system, wherein the drying drum 2 is an outer drum of the washer-dryer, and a rotatable inner drum is arranged inside the outer drum, and the inner drum is used to accommodate clothes.

[0043] For example, Figure 2 As shown, the drying drum 2 is horizontally arranged, and the front end of the drying drum 2 is a loading and unloading port 22 for loading and unloading clothes. 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.

[0044] 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.

[0045] 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. The filter device 3 is connected 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. The operation is very convenient.

[0046] 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 .

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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 .

[0051] The outer shell 33 is fixedly installed between the drying air duct and the housing 1, specifically, the outer shell 33 is fixedly installed between the first drying air duct 41 and the housing 1, and the two ends of the outer shell 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 outer shell 33 of the filter device. In addition, the extension direction of the outer shell 33 and the filter assembly is preferably parallel to the axial direction of the drying drum 2 of the drying device.

[0052] 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.

[0053] Preferably, if Figures 2 to 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 ​​.

[0054] 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 direction of the first bracket 31, the second bracket 32 ​​and the shell 33 is 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.

[0055] 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.

[0056] 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.

[0057] In a first preferred situation, the second bracket 32 ​​of the present invention can move relative to the first bracket 31 along the length direction of the first bracket 31 .

[0058] 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, keep the first bracket 31 stationary and pull the second bracket 32 ​​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, disassembly is more convenient, and it is easy to arrange the washer-dryer.

[0059] In the second preferred situation, the second bracket 32 ​​of the utility model is detachably connected to the first bracket 31 .

[0060] 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.

[0061] Preferably, if Figures 4 to 7 As shown, the filtering device 3 of the utility model also includes a locking pin 34, on which a first locking structure 341 is provided, and on which a second locking structure 323 is provided. When the locking pin 34 is in a locked position, the first locking structure 341 cooperates with the second locking structure 323 to lock the second bracket 32 ​​to the first bracket 31. When the locking pin 34 is in an unlocked position, the first locking structure 341 separates from the second locking structure 323 so that the second bracket 32 ​​can be removed from the first bracket 31.

[0062] 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.

[0063] 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 323. For example, the first locking structure 341 and the second locking structure 323 can be set as a structure in which two locking hooks cooperate with each other, or as a structure in which a locking hook and a locking mouth cooperate with each other, or as a structure in which a locking column and a locking hole cooperate with each other, and so on.

[0064] 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.

[0065] Preferably, if Figures 4 to 7As shown, a first accommodating cavity 311 is provided on the first bracket 31, and the locking pin 34 is located in the first accommodating cavity 311. An opening 312 is provided on the side of the first accommodating cavity 311 facing the second locking structure 323, and the first locking structure 341 extends through the opening 312 to the outside of the first accommodating cavity 311 so as to cooperate with the second locking structure 323.

[0066] For example, Figures 4 to 7 As shown, the first accommodating cavity 311 is arranged near the right end of the first bracket 31, the locking pin 34 is located in the first accommodating cavity 311, the first locking structure 341 faces the right end surface of the first bracket 31, the right end surface of the first bracket 31 is provided with a socket 314, the second locking structure 323 is arranged on the left end surface of the second bracket 32, the left end of the second bracket 32 ​​passes through the socket 314 and extends into the first bracket 31, and the second locking structure 323 and the first locking structure 341 are locked with each other.

[0067] That is to say, the locking pin 34 is installed on the first bracket 31, and correspondingly, the second locking structure 323 is arranged on the second bracket 32. Of course, the locking pin 34 can also be installed on the second bracket 32, the first accommodating cavity 311 is arranged on the second bracket 32, and the second locking structure 323 is arranged on the first bracket 31.

[0068] Preferably, if Figures 4 to 7 As shown, the first locking structure 341 is a first locking hook, and the second locking structure 323 is a second locking hook matched with the first locking hook.

[0069] For example, Figures 4 to 7 As shown, the first accommodating cavity 311 is arranged on the top surface of the first bracket 31, and the first accommodating cavity 311 is arranged in the vertical direction. The top end of the locking pin 34 extends out from the top of the first accommodating 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 is convenient for pressing the locking pin 34 downward. The first locking hook arranged on the locking pin 34 is arranged upward, and the second locking hook arranged on the second bracket 32 ​​is arranged downward. The first locking hook is located below the second locking hook. When the first locking hook and the second locking hook are hooked with each other, the first bracket 31 and the second bracket 32 ​​are locked. When the two brackets need to be disassembled, the locking pin 34 is pressed downward to separate the first locking hook from the second locking hook. The opening 312 connected to the first accommodating cavity 311 is arranged in the vertical direction to allow the first locking hook to move up and down.

[0070] Preferably, if Figures 4 to 6 As shown, the filter device 3 of the utility model also includes an elastic reset member 35 installed in the first accommodating chamber 311, and the two ends of the elastic reset member 35 are respectively connected to the inner wall of the first accommodating chamber 311 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.

[0071] Exemplarily, the elastic reset member 35 is arranged in the vertical direction and is located between the lock pin 34 and the inner bottom wall of the first accommodating cavity 311. When the lock pin 34 is pressed downward, the elastic reset member 35 is compressed. When the lock pin 34 is released, the elastic reset member 35 can push up the lock pin 34, so that the lock pin 34 moves from the unlocked position to the locked position.

[0072] Preferably, the locking pin 34 is further provided with a second accommodating cavity (not shown in the figure), and a part of the elastic reset member 35 is located in the second accommodating cavity.

[0073] For example, Figure 5 As shown, the locking pin 34 is vertically arranged, the second accommodating cavity extends along the axis of the locking pin 34 , the second accommodating cavity extends to the bottom end of the locking pin 34 , and the elastic reset member 35 is inserted into the second accommodating cavity from the bottom end of the locking pin 34 .

[0074] 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.

[0075] Preferably, if Figures 5 to 7 As shown, a first limiting structure 313 is provided on the inner wall of the first accommodating cavity 311 , and a second limiting structure 342 is provided on the locking pin 34 . The first limiting structure 313 cooperates with the second limiting structure 342 to prevent the locking pin 34 from rotating relative to the first accommodating cavity 311 .

[0076] The two limiting structures are used to limit the rotation of the locking pin 34 , thereby ensuring that the first locking structure 341 and the second locking structure 323 are reliably matched.

[0077] It should be noted that the utility model does not limit the specific structural form of the first limiting structure 313 and the second limiting structure 342. For example, it can be set as 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.

[0078] Preferably, if Figures 5 to 7 As shown, the first limiting structure 313 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.

[0079] For example, Figures 5 to 7 As shown, the strip-shaped limiting groove extends in the vertical direction, the strip-shaped limiting rib extends in the axial direction of the locking pin 34 , and the strip-shaped limiting rib is inserted into the strip-shaped limiting groove to prevent the locking pin 34 from rotating relative to the first accommodating cavity 311 .

[0080] It should be noted that, in practical applications, those skilled in the art may also set the first limiting structure 313 as a strip-shaped limiting rib, and correspondingly set the second limiting structure 342 as a strip-shaped limiting groove.

[0081] Preferably, if Figure 3 and Figure 4 As shown, the filter device 3 of the present invention further includes a position detection component 36, and the position detection component 36 is used to detect whether the filter component moves to the set installation position.

[0082] By providing a position detection component 36 to detect whether the filter component is installed in place, it is possible to avoid the situation where the filtering effect is affected because the filter component is not moved to the set installation position.

[0083] Preferably, if Figure 3 and Figure 4 As shown, the position detection assembly 36 of the present invention includes a first position detection component 361 and a second position detection component 362 that can cooperate and trigger.

[0084] Among them, the first position detection component 361 is installed on the housing 33 of the filter device 3, and the second position detection component 362 is installed on the filter assembly of the filter device 3. When the filter assembly moves to the set installation position, the first position detection component 361 and the second position detection component 362 cooperate to trigger.

[0085] It should be noted that those skilled in the art can install the second position detection member 362 on the first bracket 31 of the filter assembly, or can also install it on the second bracket 32. Of course, it is preferred to install the second position detection member 362 on the second bracket 32, so that only when the second bracket 32 ​​moves to the set installation position, the first position detection member 361 and the second position detection member 362 will cooperate to trigger, avoiding the situation where the user forgets to install the second bracket 32.

[0086] In addition, it should be noted that the present invention does not limit the specific structural form of the first position detection component 361 and the second position detection component 362. For example, it can be set to the structural form of a trigger member and a micro switch, or set to the structural form of a trigger member and a proximity switch, and so on.

[0087] Preferably, if Figure 3 and Figure 4 As shown, the first position detection component 361 is a proximity switch, and the second position detection component 362 is a triggering member for triggering the proximity switch.

[0088] The proximity switch is mounted on the housing 33, and the trigger is mounted on the filter assembly, preferably on the second bracket 32 ​​of the filter assembly.

[0089] It should be noted that, in actual applications, those skilled in the art may also set the second position detection component 362 as a proximity switch and the first position detection component 361 as a trigger member for triggering the proximity switch, that is, install the proximity switch on the filter assembly and install the trigger member on the housing 33.

[0090] In addition, it should be noted that the present invention does not limit the specific type of proximity switch. For example, a Hall proximity switch or a capacitive proximity switch may be used, and the specific structure of the triggering element is selected according to the type of proximity switch.

[0091] Preferably, the proximity switch is a reed switch, and the triggering member is a magnet.

[0092] Exemplarily, the reed switch proximity switch includes a metal housing, a reed switch and contacts. The working principle is to use the principle of magnetic induction to act on the reed switch through an external magnetic field, so that the reed inside the reed switch closes or opens the contact, thereby realizing the closing or opening of the switch.
