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 utility model can be understood according to specific situations.

[0042] Specifically, as Figure 1 and Figure 2 shown, the washing and drying integrated machine of the present application includes a cabinet 1, a drying cylinder 2 installed in the cabinet 1, and a drying system. The drying system can blow hot air into the drying cylinder 2. Among them, the drying cylinder 2 is the outer cylinder of the washing and drying integrated machine, and a rotatable inner cylinder is arranged inside the outer cylinder. The inner cylinder is used to accommodate clothes.

[0043] Exemplarily, as Figure 2As shown, the drying cylinder 2 is horizontally arranged. The front end of the drying cylinder 2 is a loading and unloading opening 22 for loading and unloading clothes. A ventilation opening 21 is provided near the rear end of the drying cylinder 2. The ventilation opening 21 is communicated with the air inlet end of the drying system. The air outlet end of the drying system extends to the loading and unloading opening 22 of the drying cylinder 2. During the drying process, the wet air in the drying cylinder 2 enters the drying system through the ventilation opening 21, and after being condensed and heated by the drying system, it re-enters the drying cylinder 2 through the loading and unloading opening 22 to dry the clothes in the drying cylinder 2.

[0044] Preferably, as Figure 1 and Figure 2 shown, the drying system of the present utility model includes a drying air duct and a filtering device. A first insertion interface 411 is provided on the drying air duct, and a part of the filtering device passes through the first insertion interface 411 and extends into the drying air duct.

[0045] Among them, the filtering device is used to filter the air flow in the drying air duct and intercept impurities such as lint carried by the air flow. By connecting the filtering device and the drying air duct in a plug-in manner, when the filtering device needs to be cleaned, the filtering device can be pulled out from the drying air duct, and after cleaning, it can be inserted into the drying air duct from the first insertion interface 411, and the operation is very convenient.

[0046] Preferably, as Figure 1 shown, the cabinet 1 of the washing and drying integrated machine of the present utility model is provided with a second insertion interface 11 at a position corresponding to the first insertion interface 411. The extending direction of the filtering device is parallel to the axis direction of the drying cylinder 2 of the washing and drying integrated machine, and the filtering device extends to the second insertion interface 11.

[0047] Exemplarily, the second insertion interface 11 is arranged on the front panel of the cabinet 1. When the filtering device needs to be cleaned, the user can directly pull out the filtering device from the front panel.

[0048] Preferably, as Figure 1 and Figure 2 shown, the drying air duct of the present 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 communicated with the ventilation opening 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 communicated with one end of the second drying air duct 42. The other end of the second drying air duct 42 extends towards the loading and unloading opening 22 of the drying cylinder 2. The first insertion interface 411 is arranged on the first drying air duct 41.

[0049] Exemplarily, as 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 cylinder 2 and horizontally arranged. The extending direction of the first drying air duct 41 is perpendicular to the axial direction of the drying cylinder 2, and the extending 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 cross - arranged, 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.

[0050] Preferably, as Figures 1 to 4 shown, the filtering device of the present application includes a housing 33 and a filtering component installed on the housing 33. The filtering component can move relative to the housing 33 along the length direction of the housing 33.

[0051] Among them, the housing 33 is fixedly installed between the drying air duct and the box body 1. Specifically, the housing 33 is fixedly installed between the first drying air duct 41 and the box body 1. The two ends of the housing 33 are respectively communicated with the first insertion interface 411 on the first drying air duct 41 and the second insertion interface 11 on the box body 1. A part of the filtering component passes through the first insertion interface 411 and extends into the drying air duct, specifically into the first drying air duct 41. The filtering component extends to the second insertion interface 11. When the filtering device needs to be cleaned, only the filtering component needs to be pulled out, and there is no need to disassemble the housing 33 of the filtering device. In addition, the extending directions of the housing 33 and the filtering component are preferably parallel to the axial direction of the drying cylinder 2 of the drying device.

[0052] It should be noted that the setting of the housing 33 is not necessary. Those skilled in the art can also cancel the setting of the housing 33 according to the actual situation in practical applications.

[0053] Preferably, as Figures 3 to 9 shown, the filtering component of the present utility model includes a pull - out bracket 31, a filter screen frame 32 installed on the pull - out bracket 31, and a filter screen installed on the filter screen frame 32.

[0054] Among them, the pull - out bracket 31 is installed on the housing 33 and can move relative to the housing 33 along the length direction of the housing 33. The pull - out bracket 31 and the filter screen frame 32 are distributed along the length direction of the housing 33. The extending directions of the pull - out bracket 31 and the filter screen frame 32 are both parallel to the axial direction of the drying cylinder 2 of the washing - drying integrated machine. The pull - out bracket 31 extends to the second insertion interface 11, and the filter screen frame 32 and the filter screen pass through the first insertion interface 411 and extend into the drying air duct, specifically, the filter screen frame 32 and the filter screen pass through the first insertion interface 411 and extend into the first drying air duct 41.

[0055] It should be noted that in actual applications, those skilled in the art can make the entire filter screen frame 32 extend into the first drying air duct 41, or only make the filter screen frame 32 with the filter screen part installed extend into 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 invention and should all be defined within the protection scope of the present invention. Of course, preferably, only a part of the filter screen frame 32 extends into the first drying air duct 41 in the present invention.

[0056] In addition, it should also be noted that in actual applications, those skilled in the art can make the entire filter screen extend into the first drying air duct 41, or only make a part of the filter screen extend into 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 invention and should all be defined within the protection scope of the present invention. Of course, preferably, the entire filter screen extends into the first drying air duct 41 in the present invention.

[0057] In addition, it should also be noted that the setting of the draw-out bracket 31 is not necessary. Those skilled in the art can cancel the setting of the draw-out bracket 31 according to specific circumstances in actual applications.

[0058] Preferably, as Figures 5 to 7 shown, the filter screen frame 32 of the present invention is detachably and fixedly connected to the draw-out bracket 31.

[0059] When the filter screen needs to be cleaned, first pull out the draw-out bracket 31 from the box body 1. After the outer end of the filter screen frame 32 moves to the outside of the box body 1 along with the draw-out bracket 31, disassemble the draw-out bracket 31 from the filter screen frame 32, and then continue to pull the filter screen frame 32 until the filter screen is pulled out. In this way, when disassembling the filtering device, less lateral space is required, the disassembly is more convenient, and it is convenient to arrange the washing and drying integrated machine.

[0060] Exemplarily, as Figure 5 shown, the left end of the draw-out bracket 31 along its length direction is detachably and fixedly connected to the right end of the filter screen frame 32 along its length direction.

[0061] Preferably, as Figures 6 to 9 shown, the filter screen frame 32 of the present invention includes a first filter screen frame 321 and a second filter screen frame 322 arranged side by side. The filter screen includes a first filter screen 351 installed on the first filter screen frame 321 and a second filter screen 352 installed on the second filter screen frame 322.

[0062] By arranging the first filter screen 351 and the second filter screen 352 side by side on the filter screen frame 32, the filtering effect of the filtering device can be improved.

[0063] In the case where the draw-out bracket 31 is provided, the first filter screen frame 321 is detachably and fixedly connected to the draw-out bracket 31.

[0064] Preferably, as Figure 8 and Figure 9 shown, the first filter screen 351 is located upstream of the second filter screen 352, and the mesh number of the first filter screen 351 is smaller than that of the second filter screen 352.

[0065] Exemplarily, the air flow in the first drying air duct 41 first flows through the first filter screen 351 and then through the second filter screen 352. The mesh number of the first filter screen 351 is smaller than that of the second filter screen 352. Among them, the mesh number of the first filter screen 351 can be set between 40 and 80, and the mesh number of the second filter screen 352 can be set between 80 and 160.

[0066] Preferably, as Figure 9 shown, one end of the first filter screen frame 321 is pivotally connected to one end of the second filter screen frame 322.

[0067] By pivotally connecting the first filter screen frame 321 and the second filter screen frame 322, when it is necessary to clean the first filter screen 351 and the second filter screen 352, the first filter screen frame 321 and the second filter screen frame 322 can be opened at a certain angle (such as 90 degrees or 150 degrees, etc.), which is convenient for cleaning the first filter screen 351 and the second filter screen 352 and improves the cleaning effect of the first filter screen and the second filter screen.

[0068] Exemplarily, the first end of the first filter screen frame 321 along its length direction is pivotally connected to the first end of the second filter screen frame 322 along its length direction, and the second end of the first filter screen frame 321 along its length direction is detachably and fixedly connected to the draw-out bracket 31.

[0069] Preferably, as Figure 5 , Figure 6 and Figure 8 shown, the filter screen frame 32 of the present utility model is provided with a receiving cavity 3211. The receiving cavity 3211 is located upstream of the filter screen and can receive the lint intercepted by the filter screen.

[0070] By providing the receiving cavity 3211 on the filter screen frame 32 to collect the filtered lint, when the filter screen and the filter screen frame 32 are drawn out from the drying air duct, it is convenient for the lint to come out together with the filter screen frame 32, which is beneficial to preventing the lint from being intercepted in the drying air duct. If the lint is intercepted in the drying air duct, during the next drying, these lint will adhere to the filter screen again, resulting in the need to frequently clean the filter screen, seriously affecting the user experience. Especially when drying woolen clothes, the amount of lint of woolen clothes is large. In the case of not setting the receiving cavity 3211, the filter screen needs to be cleaned after each drying. In the case of setting the receiving cavity 3211, the service life of the filtering device can be greatly extended, the number of times the user cleans the filter screen can be reduced, and the user experience is greatly improved.

[0071] Exemplarily, the receiving cavity 3211 is provided on the first filter screen frame 321. The lint intercepted by the first filter screen is collected in the receiving cavity 3211. When the filter screen needs to be cleaned, the lint in the receiving cavity 3211 is drawn out together with the filter screen frame 32.

[0072] Preferably, the depth of the receiving cavity 3211 is 5 to 15 mm.

[0073] Exemplarily, those skilled in the art can set the depth of the receiving cavity 3211 to 5 mm, 7 mm, 9 mm, 10 mm, 12 mm, 14 mm, 15 mm, etc., and further preferably set it to 10 mm.

[0074] Wherein, the depth of the receiving cavity 3211 refers to the dimension along the thickness direction of the filter screen frame 32, or, it can also be understood as the dimension along the flow direction of the air flow.

[0075] Preferably, as Figure 5 、 Figure 6 and Figure 10 shown, the filter screen frame 32 is provided with strip-shaped ribs at the inlet position of the receiving cavity 3211. The strip-shaped ribs divide the inlet of the receiving cavity 3211 into multiple sub-inlets to improve the uniformity of the air flow.

[0076] Wherein, the side of the receiving cavity 3211 away from the filter screen is the inlet. The air flow in the drying air duct enters the receiving cavity 3211 from this inlet, and then flows towards the filter screen. By setting strip-shaped ribs at the inlet position, the strip-shaped ribs can divide the air flow and improve the uniformity of the air flow, which is beneficial to make the entire filtering surface of the filter screen have air flow passing through and improve the filtering effect. In addition, by setting strip-shaped ribs at the inlet of the receiving cavity 3211, the strip-shaped ribs can press on the lint to prevent the lint in the receiving cavity 3211 from escaping from the receiving cavity 3211.

[0077] It should be noted that the number of the strip-shaped ribs can be one or more. In addition, the strip-shaped ribs can extend along the length direction of the receiving cavity 3211, or can extend along the width direction of the receiving cavity 3211, or can also extend obliquely, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should all be defined within the protection scope of the present invention.

[0078] Preferably, as Figure 5 、 Figure 6 and Figure 10 shown, the strip-shaped ribs include a first strip-shaped rib 3231 and a second strip-shaped rib 3232 which are arranged crosswise.

[0079] By arranging the first strip-shaped rib 3231 and the second strip-shaped rib 3232 crosswise, it is more beneficial to provide the uniformity of the air flow and is also more beneficial to prevent the lint from escaping from the receiving cavity 3211.

[0080] Preferably, as Figure 5 , Figure 6 and Figure 10 shown, the first strip-shaped rib 3231 extends along the length direction of the inlet of the accommodation cavity 3211, the second strip-shaped rib 3232 extends along the width direction of the inlet of the accommodation cavity 3211, and the number of the second strip-shaped ribs 3232 is at least two and they are spaced apart along the length direction of the inlet of the accommodation cavity 3211.

[0081] Exemplarily, the inlet of the accommodation cavity 3211 is rectangular, the first strip-shaped rib 3231 extends along the length direction of the inlet and the number is one, the second strip-shaped rib 3232 extends along the width direction of the inlet and the number is two. That is to say, the first strip-shaped rib 3231 and the second strip-shaped rib 3232 are perpendicularly arranged. One first strip-shaped rib 3231 and two second strip-shaped ribs 3232 divide the inlet of the accommodation cavity 3211 into six sub-inlets. The accommodation cavities 3211 corresponding to the six sub-inlets will all be covered with lint, avoiding all the lint concentrating in some areas.

[0082] Preferably, as Figure 5 , Figure 6 and Figure 10 shown, a frame 323 is provided on the filter screen frame 32. One end of the frame 323 is pivotally connected to the filter screen frame 32, and the strip-shaped ribs are provided on the frame 323.

[0083] Exemplarily, one end of the frame 323 along its length direction is pivotally connected to one end of the first filter screen frame 321 along its length direction. When it is necessary to clean the lint in the accommodation cavity 3211, the frame 323 is rotated by a certain angle (such as 90 degrees or 150 degrees, etc.) relative to the first filter screen frame 321 to open the inlet of the accommodation cavity 3211, so as to facilitate cleaning the lint in the accommodation cavity 3211. That is to say, the frame 323 and the strip-shaped ribs on the frame 323 are equivalent to a door cover, which can prevent the lint in the accommodation cavity 3211 from escaping from the inlet of the accommodation cavity 3211.

[0084] Preferably, as Figure 6 and Figure 8 shown, an opening 3213 is provided at the top of the accommodation cavity 3211. The drying system further includes a spraying mechanism arranged in the drying air duct. The spraying mechanism is located above the filter screen frame 32 and can spray water towards the accommodation cavity 3211.

[0085] By arranging the spraying mechanism, the spraying mechanism can regularly spray water into the accommodation cavity 3211 of the filter screen frame 32 to wash the lint located in the accommodation cavity 3211. In this way, the number of times for the user to clean the filter screen can be further reduced, and the user experience can be further improved.

[0086] Exemplarily, three openings 3213 are provided at the top of the accommodation cavity 3211. The three openings 3213 are distributed along the length direction of the accommodation cavity. The water flow sprayed by the spraying mechanism passes through the openings 3213 to wash the lint in the accommodation cavity 3211.

[0087] It should be noted that the present utility model does not limit the specific structural form of the spraying mechanism. For example, those skilled in the art can set the spraying mechanism as a spraying pipe and install it on the inner wall of the drying air duct, so that the spraying pipe is located directly above the accommodation cavity 3211. The spraying pipe extends along the length direction of the accommodation cavity 3211, and a plurality of water spraying holes are opened at the bottom of the spraying pipe to spray water into the accommodation cavity 3211. Or, a water spraying cavity can also be provided in the upper cover of the drying air duct, so that the water spraying cavity is located directly above the accommodation cavity 3211. The water spraying cavity extends along the length direction of the accommodation cavity 3211, and a plurality of water spraying holes are opened at the bottom of the water spraying cavity to spray water into the accommodation cavity 3211, and so on.

[0088] Preferably, as Figures 5 to 9 shown, the filtering device of the present utility model further includes a locking pin 34. The locking pin 34 is installed on the pulling bracket 31. A first locking structure 341 is provided on the locking pin 34, and a second locking structure 3212 is provided on the first filter screen frame 321 of the filter screen frame 32. When the locking pin 34 is in the locking position, the first locking structure 341 cooperates with the second locking structure 3212 to lock the first filter screen frame 321 of the filter screen frame 32 to the pulling bracket 31. When the locking pin 34 is in the unlocking position, the first locking structure 341 is separated from the second locking structure 3212, so that the first filter screen frame 321 of the filter screen frame 32 can be detached from the pulling bracket 31.

[0089] The present utility model locks the pulling bracket 31 and the first filter screen frame 321 of the filter screen frame 32 through the locking pin 34. When it is necessary to disassemble the pulling bracket 31 from the filter screen frame, the locking pin 34 can be unlocked.

[0090] It should be noted that the present utility model does not limit the specific structural forms of the first locking structure 341 and the second locking structure 3212. For example, the first locking structure 341 and the second locking structure 3212 can be set as a structure in which two locking hooks cooperate, or a structure in which a locking hook cooperates with a locking mouth, or a structure in which a locking column cooperates with a locking hole, and so on.

[0091] Preferably, as Figures 5 to 9 shown, the first locking structure 341 is a locking hook, and the second locking structure 3212 is a locking mouth adapted to the locking hook. A part of the locking hook can be inserted into the locking mouth.

[0092] Exemplarily, as Figures 5 to 9As shown in the figure, the locking pin 34 is vertically installed on the drawing bracket 31. The locking hook provided on the locking pin 34 is upwardly arranged. The number of locking hooks is two and they are spaced apart along the axial direction of the locking pin 34.
