[0003] Taking the washer-dryer as an example, the heating methods of the existing washer-dryers on the market are mostly electric heating or heat pump heating. No matter which heating method is chosen, the circulating air duct during the drying process is indispensable. During the drying process, the lint on the clothes will fall off, be carried by the fan and attached to the entire air duct.

[0004] To avoid the above situation, many integrated washing and drying machines choose to install a filter device in the drying air duct to filter the lint. However, with the use of the integrated washing and drying machine, a large amount of lint will accumulate on the filter device, and since the filter device is installed in the drying air duct, it is inconvenient to clean.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content

[0038] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "connect", and "install" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] 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.

[0040] For example, Figure 2As 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.

[0041] 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.

[0042] 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.

[0043] 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 .

[0044] 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.

[0045] 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.

[0046] For example, Figure 1 and Figure 2As 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.

[0047] 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 .

[0048] 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.

[0049] 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.

[0050] Preferably, if Figure 3 and Figure 4 As shown, the filter assembly of the utility model includes a bracket and a filter screen installed on the bracket (not shown in the figure), the bracket can move relative to the shell 33 along the length direction of the shell 33, and a part of the bracket and the filter screen pass through the first plug interface 411 and extend into the drying air duct.

[0051] Furthermore, if Figure 3 and Figure 4 As shown, the support of the filter assembly includes a first support 31 and a second support 32 installed on the first support 31 , and the filter screen is installed on the second support 32 .

[0052] 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.

[0053] In the first preferred case, if Figures 3 to 5 As shown, the second bracket 32 ​​of the present invention is detachably connected to the first bracket 31 .

[0054] 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.

[0055] Furthermore, if Figure 4 and Figure 5 As shown, the filtering device 3 of the utility model also includes a locking pin 34, a first locking structure is provided on the locking pin 34, and a second locking structure 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 cooperates with the second locking structure 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 is separated from the second locking structure so that the second bracket 32 ​​can be removed from the first bracket 31.

[0056] 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.

[0057] It should be noted that the utility model does not limit the specific structural form of the first locking structure and the second locking structure. For example, the first locking structure and the second locking structure 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.

[0058] 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.

[0059] In a second 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 .

[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, 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.

[0061] Preferably, if Figure 3 As shown, an elastic structure 35 is provided at the end of the filter device 3 of the present invention, and the elastic structure 35 is tightly pressed against the first inner wall of the drying air duct, which is the inner wall of the drying air duct opposite to the first plug port 411 .

[0062] Among them, the elastic structure 35 is arranged at the end of the bracket of the filtering device (the end inserted into the drying air duct), and the elastic structure 35 abuts against the inner wall of the first drying air duct 41, which can seal the gap between the end of the bracket and the first inner wall to prevent the wire scraps carried by the airflow from passing through, thereby improving the filtering effect.

[0063] Preferably, if Figure 4 and Figure 5 As shown, a receiving groove 36 is provided at the end of the bracket, and a part of the elastic structure 35 is embedded in the receiving groove 36 .

[0064] Exemplarily, an accommodation groove 36 is provided at the end of the second bracket 32 ​​, and a portion of the elastic structure 35 is embedded in the accommodation groove 36 , so that the elastic structure 35 is fixed to the second bracket 32 ​​.

[0065] Of course, those skilled in the art can also set the elastic structure 35 and the bracket in one piece in practical applications. Specifically, the bracket of the filter device is generally made of plastic material, and the elastic structure 35 is made of rubber material, and double injection molding can be performed to directly integrate the elastic structure 35 and the second bracket 32 ​​into one piece.

[0066] Preferably, if Figure 3 and Figure 6 As shown, the elastic structure 35 of the present invention includes a main body portion 351 and abutting portion 352 which are connected to each other. The main body portion 351 is embedded in the filter device, and the butting portion 352 is butted against the first inner wall of the first drying air duct 41 .

[0067] For example, Figure 6 As shown, the main body 351 of the elastic structure 35 is a plate-like structure, which is vertically arranged. A supporting portion 352 is provided at the front end of the main body 351 , and the supporting portion 352 is arranged in a strip shape.

[0068] Preferably, if Figure 6 As shown, the thickness of the abutting portion 352 gradually decreases in a direction away from the main body portion 351 .

[0069] By gradually reducing the thickness of the abutting portion 352 in the direction away from the main body portion 351 , the abutting portion 352 is more likely to deform, so that it can abut more tightly against the first inner wall of the drying air duct, thereby improving the sealing effect.

[0070] Those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present application and form different embodiments. For example, in the claims of the present application, any one of the claimed embodiments may be used in any combination.

[0071] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
