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

[0037] 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.

[0038] 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.

[0039] 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, wherein at least a portion of the filter device 3 is located in the drying air duct to filter the airflow in the drying air duct.

[0040] When the drying process is executed, the air flow circulates in the drying drum and the drying duct of the drying system. When the air flow flows through the drying drum, the lint on the clothes will flow with the air flow. By arranging a filter device 3 in the drying duct, the air flow can be filtered to block the lint carried by the air flow.

[0041] Preferably, if Figure 1 and Figure 2 As shown, a first plug port 411 is provided on the drying air duct, and a portion of the filter device 3 passes through the first plug port 411 and extends into the drying air duct.

[0042] 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.

[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 2As 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 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 drum 2. When the drying drum 2 is horizontally arranged, the first drying air duct 41 and the second drying air duct 42 are both located above the drying drum 2. In addition, the extension direction of the first drying air duct 41 intersects with the extension direction of the second drying air duct 42. Further, 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 vertically arranged, 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 2 As shown, the extension direction of the second drying air duct 42 is perpendicular to the axial direction of the fan 5 .

[0048] Among them, 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 with 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 with 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.

[0049] Preferably, if Figure 2 As shown, the air outlet 21 is arranged on the side wall of the drying cylinder 2.

[0050] Compared with arranging the exhaust port 21 on the rear wall of the drying drum 2 , arranging the exhaust port 21 on the side wall of the drying drum 2 facilitates connecting the first drying air duct 41 with the exhaust port 21 .

[0051] Preferably, the drying system of the present invention also 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 is located downstream of the filtering device 3, and the condenser of the heat pump module is installed in the second drying air duct 42.

[0052] Among them, Figure 2As shown, after the humid air flow 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 air flow is condensed into water. The air flow passes through the fan 5 and enters the second drying air duct 42. After being heated by the condenser, it returns to the drying drum 2 to dry the clothes in the drying drum 2.

[0053] 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 .

[0054] 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.

[0055] 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.

[0056] Preferably, if Figures 2 to 8 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 34 installed on the second bracket 32 ​​.

[0057] 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.

[0058] 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 the second bracket 32 ​​with the filter 34 installed can be extended into the first drying air duct 41, etc. Such flexible adjustment and change 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 only allows a portion of the second bracket 32 ​​to extend into the first drying air duct 41.

[0059] Preferably, if Figures 4 to 7 As shown, 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 34 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 34 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] It should be noted that, in actual application, those skilled in the art may also set the second bracket 32 ​​to be detachably connected to 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 with the first bracket 31, the first bracket 31 and the second bracket 32 ​​are disassembled, and then the second bracket 32 ​​is continued to be pulled until the filter 34 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.

[0062] Preferably, if Figures 5 to 8 As shown, a water spraying structure is provided on the drying air duct of the utility model, and the water spraying structure can spray water toward the filtering device 3 .

[0063] By providing a water spray structure on the drying air duct, water can be sprayed toward the filter screen 34 on the filter device 3 regularly through the water spray structure to wash away the wire scraps on the filter screen 34. In this way, the number of manual cleaning of the filter device can be reduced, and the user experience can be improved. In addition, when a water spray structure is provided, the filter device can also be set to be non-detachable, and the filter screen 34 can be cleaned by the water spray structure.

[0064] The water spray structure is arranged on the first drying air duct 41, and the water spray structure is connected to a water source.

The water source can be set as a water storage tank installed in the housing of the washer-dryer, and a water pump is arranged in the water tank, and the water outlet of the water pump is connected to the water spray structure through a water pipe.

[0065] It should be noted that, in order to facilitate the discharge of water and lint, a drain port is provided at the bottom of the drying air duct, and the drain port is connected to the water drainage pipeline. When cleaning the filter 34, water and lint can enter the drainage pipeline through the drain port and be discharged.

[0066] In addition, it should be noted that a person skilled in the art may integrate the water spray structure with the drying air duct, or may configure the water spray structure as an independent component and then fix it on the drying air duct. Such flexible adjustments and changes do not deviate from the principle and scope of the present utility model and shall be limited within the protection scope of the present utility model.

[0076] Among them, the filtering surface of the filtering device is the filter surface. For example, the filter 34 is vertically arranged, and the filter surface is also vertical. The angle between the extension line of the water spray channel 413 and the filter surface is the angle between the extension line of the water spray channel 413 and the vertical surface. By limiting this angle, the cleaning area of ​​the water spray structure can be guaranteed. The smaller the angle, the larger the cleaning area of ​​the water spray structure.

[0077] For example, those skilled in the art can set the angle between the extension line of the water spray channel 413 and the filtering surface of the filtering device to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°.
