For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0049] 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.
[0050] 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 to 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.
[0051] 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.
[0052] 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.
[0053] 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 .
[0054] 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.
[0055] 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.
[0056] 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.
[0057] 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 .
[0058] 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.
[0059] 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.
[0060] 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 .
[0061] 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.
[0062] 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.
[0063] 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.
[0064] Preferably, if Figures 4 to 7 As shown, the second bracket 32 of the present invention is detachably connected to the first bracket 31 .
[0065] 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.
[0066] Preferably, if Figures 4 to 7 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.
[0067] 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.
[0068] 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.
[0069] 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.
[0070] It should be noted that, in actual applications, those skilled in the art may also configure the second bracket 32 to be movable relative to the first bracket 31 along the length direction of the first bracket 31 .
[0071] In this way, when the filter needs to be cleaned, the first bracket 31 is first pulled 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, the first bracket 31 remains 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, disassembly is more convenient, and it is easy to arrange the washer-dryer.
[0072] Preferably, if Figures 5 to 7 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 .
[0073] By providing a water spray structure on the drying air duct, water can be sprayed toward the filter screen on the filter device 3 regularly through the water spray structure to wash away the wire scraps on the filter screen. In this way, the number of manual cleaning of the filter device 3 can be reduced, and the user experience can be improved. In addition, when a water spray structure is provided, the filter device 3 can also be set to be non-detachable, and the filter screen can be cleaned by the water spray structure.
[0074] The water spray structure is arranged on the first drying air duct 41, and the water spray structure is connected to a water source. When the filter screen of the filter device 3 needs to be cleaned, water is supplied to the water spray structure through the 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. The water outlet of the water pump is connected to the water spray structure through the first water pipe 71.
[0075] It should be noted that in order to facilitate the discharge of water and lint, a drain outlet is provided at the bottom of the drying duct, and the drain outlet is connected to the water drainage pipeline. When cleaning the filter, water and lint can enter the drainage pipeline through the drain outlet and be discharged.
[0076] 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.
[0077] Preferably, if Figures 5 to 7 As shown, the water spray structure of the utility model includes a water spray chamber 412 and a water spray channel 413. The water spray chamber 412 is located above the filter device 3 and extends along the length direction of the filter device 3. The top end of the water spray channel 413 is connected to the water spray chamber 412, and the bottom end of the water spray channel 413 faces the filter device 3.
[0078] Exemplarily, a water spray chamber 412 is formed at the top of the first drying air duct 41. The water spray chamber 412 is long and is located above the second bracket 32 of the filter device 3. The water spray channel 413 is arranged at the bottom of the water spray chamber 412. After the water in the water source enters the water spray chamber 412, it is sprayed onto the filter screen on the second bracket 32 through the water spray channel 413.
[0079] It should be noted that the present invention does not limit the shape of the water spray channel 413. For example, those skilled in the art may configure the water spray channel 413 as an integral long channel, or may configure the water spray channel 413 as a columnar channel, etc.
[0080] Preferably, if Figures 5 to 7 As shown, the water spray channel 413 is cylindrical and there are multiple water spray channels 413 , which are spaced apart along the length direction of the filter device 3 .
[0081] That is to say, a plurality of water spray channels 413 are spaced apart along the length direction of the water spray chamber 412, and the water spray channels 413 are columnar.
[0082] The cross section of the water spray channel 413 can be set to be circular, square, rectangular or elliptical, etc.
[0083] Preferably, if Figures 5 to 7 As shown, the cross-sectional area of the water spray channel 413 gradually decreases in a direction away from its top end.
[0084] That is to say, the cross-sectional area of the water spray channel 413 gradually decreases from the top end to the bottom end of the water spray channel 413, so that the spraying speed of the water flow can be increased, thereby improving the cleaning effect of the water spray structure.
[0085] Preferably, if Figures 5 to 7 As shown, the angle between the water spray channel 413 and the filter surface of the filter device 3 along the extension line is not greater than 10°.
[0086] Among them, the filtering surface of the filter device 3 is the filter screen surface. For example, the filter screen is vertically arranged, and the filter screen surface is also vertical. The angle between the extension line of the water spray channel 413 and the filter screen surface is the angle between the extension line of the water spray channel 413 and the vertical plane. 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.
[0087] 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 3 to 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9° or 10°. Further preferably, the angle between the extension line of the water spray channel 413 and the vertical plane is not greater than 5°.
[0088] Preferably, if Figure 1 and Figure 2 As shown, the drying air duct of the present invention further includes a bellows 43 , and the first drying air duct 41 is connected to the exhaust port 21 on the drying cylinder 2 through the bellows 43 .
[0089] That is to say, the bellows 43 forms the air inlet end of the drying air duct. After being discharged from the air outlet 21 , the airflow in the drying cylinder 2 first enters the bellows 43 and then enters the first drying air duct 41 .
[0090] Preferably, if Figure 5 and Figure 8 As shown, the drying system of the present invention also includes a flushing component 6 installed on the drying air duct, the flushing component 6 is arranged close to the air inlet end of the drying air duct, the first end of the flushing component 6 is connected to the water source, and the second end of the flushing component 6 extends into the drying air duct and can spray water to clean the lint in the drying air duct.
[0091] By providing the flushing member 6, the wire scraps accumulated at the air inlet end of the drying air duct can be flushed to ensure the drying efficiency. The flushing member 6 is specifically installed on the corrugated tube 43, and the flushing member 6 can clean the wire scraps accumulated in the corrugated tube 43.
[0092] It should be noted that the water source can be a water storage tank installed in the housing of the washer-dryer, 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 the second water pipe 72. The flushing component 6 and the water spray structure on the drying air duct described above preferably share the same water source.
[0093] Preferably, if Figures 8 to 11As shown, the second end of the flushing component 6 of the present invention has at least two water spraying ports spraying in different directions.
[0094] By providing a plurality of water spraying ports that spray in different directions, the cleaning range of the flushing component 6 can be increased, thereby improving the cleaning effect on the drying air duct.
[0095] Preferably, if Figures 8 to 11 As shown, the flushing component 6 of the utility model includes a tubular body 61 and a plate-like structure 62 arranged on the tubular body 61, the first end of the tubular body 61 is provided with a water inlet 63 connected to a water source, the second end of the tubular body 61 is provided with a water outlet, the plate-like structure 62 is arranged opposite to the water outlet, and there is a gap between the plate-like structure 62 and the second end of the tubular body 61, the gap forms a first water spray outlet 64, and a second water spray outlet 65 is provided on the plate-like structure 62, the second water spray outlet 65 is directly opposite to the water outlet and the flow area of the second water spray outlet 65 is smaller than the flow area of the water outlet.
[0096] After the water in the water source enters the tubular body 61 along the second water pipe 72, it flows toward the water outlet along the channel inside the tubular body 61. The water discharged from the water outlet rushes toward the plate-like structure 62, and part of the water will be sprayed out from the second water spray port 65 on the plate-like structure 62. Since the flow area of the second water spray port 65 is smaller than the flow area of the water outlet, part of the water will collide with the plate-like structure 62. The water after the collision will be sprayed out from the first water spray port 64. By colliding with the plate-like structure 62, the water will splash everywhere, thereby increasing the cleaning range of the flushing component 6.
[0097] Exemplarily, the cross-section of the tubular body 61 is circular, the second water spray port 65 is also circular, the diameter of the second water spray port 65 is smaller than the diameter of the water outlet, that is, the flow area of the second water spray port 65 is smaller than the flow area of the water outlet, the plate-like structure 62 is approximately a fan-shaped structure, and the end face of the second end of the tubular body 61 is provided with an arc-shaped connecting portion, the arc-shaped connecting portion extends from the end face of the second end along the length direction of the tubular body 61, the plate-like structure 62 is connected to the arc-shaped connecting portion, and the ratio of the arc length of the arc-shaped connecting portion to the circumference of the end face of the second end of the tubular body 61 is not greater than 0.7, and further preferably not greater than 0.5.
[0098] Preferably, if Figures 8 to 11 As shown, the drying air duct is provided with a mounting hole 431 and a first anti-rotation structure 432 located on the inner wall of the mounting hole 431, and the tubular body 61 is provided with a second anti-rotation structure 66. The tubular body 61 is installed in the mounting hole 431, and the first anti-rotation structure 432 cooperates with the second anti-rotation structure 66 to prevent the tubular body 61 from rotating relative to the drying air duct.
[0099] Among them, the mounting hole 431 is set on the bellows 43, and the first anti-rotation structure 432 cooperates with the second anti-rotation structure 66 to prevent the flushing component 6 from rotating relative to the bellows 43, thereby avoiding the situation where the flushing effect is affected by the change of the spraying direction of the injection port on the flushing component 6.
[0100] It should be noted that the present invention does not limit the specific structural forms of the first anti-rotation structure 432 and the second anti-rotation structure 66. For example, the first anti-rotation structure 432 and the second anti-rotation structure 66 can be set as matching groove structures and plate structures, or as matching groove structures and block structures, or as matching hole structures and columnar structures, etc.
