[0002] Drying equipment refers to machines that can use hot air to dry clothes. Drying equipment mainly includes washing and drying machines, clothes dryers or dryers.

[0003] Taking a washer-dryer as an example, most existing washer-dryers on the market use either electric heating or heat pump heating. Regardless of the heating method chosen, the dryer cannot do without a circulating air duct during the drying process. During the drying process, lint from the clothes will fall off, be carried by the fan, and adhere to the entire air duct. To avoid this, many washer-dryers choose to install a filter device in the drying duct to filter out lint. In addition, to facilitate the cleaning of lint, the filter device is generally installed in the drying duct by plugging.

[0004] However, the filtering device of the existing drying equipment is limited by the space in the drying air duct, and the filtering area is relatively small, resulting in poor filtering effect and thus poor drying efficiency.

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

Those skilled in the art should understand that these embodiments are merely intended to illustrate the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the embodiments described below are described in conjunction with a washer-dryer, the technical solutions of the present invention are equally applicable to other drying appliances with drying functions, such as clothes dryers and care machines.

[0043] It should be noted that in the description of this utility model, terms such as "upper," "lower," "left," "right," "top," "bottom," "front," and "back" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or component described must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "installed" should be understood in a broad sense, for example, to refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0045] Specifically, if 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 the outer drum of the washer-dryer, and a rotatable inner drum is provided in the outer drum, and the inner drum is used to accommodate clothes.

[0046] For example, Figure 2 As shown, the drying drum 2 is arranged horizontally, and the front end of the drying drum 2 is a take-in and put-out port 22 for taking clothes in and out. An exhaust port 21 is provided near the rear end of the drying drum 2. The exhaust port 21 is connected to the air inlet end of the drying system, and the air outlet end of the drying system extends to the take-in and put-out port 22 of the drying drum 2. During the drying process, the humid air in the drying drum 2 enters the drying system through the exhaust port 21, and after condensation and heating by the drying system, re-enters the drying drum 2 through the take-in and put-out port 22 to dry the clothes in the drying drum 2.

[0047] Preferably, if Figure 3 and Figure 4 As shown, the drying system of the present invention includes a drying duct and a first filter device, which is arranged in the drying duct. The first filter device is used to filter the air flow in the drying duct and intercept impurities such as lint carried by the air flow.

[0048] Preferably, if Figure 4 As shown, the first filter device includes a first filter frame 61 and a first filter 62 installed on the first filter frame 61. The first filter 62 is tilted from bottom to top along the flow direction of the airflow.

[0049] The filter screen in the prior art is generally set vertically and has a small filtering area. The present application increases the filtering area of ​​the first filter screen 62 by setting the first filter screen 62 at an angle, thereby improving the filtering effect and further improving the drying efficiency.

[0050] Exemplarily, the first filter frame 61 is also tilted along with the first filter 62 .

[0051] It should be noted that the present invention does not limit the inclination angle of the first filter screen 62. For example, the inclination angle of the first filter screen 62 can be set to 10 degrees, 30 degrees, or 50 degrees, etc. Preferably, the inclination angle of the first filter screen 62 is set to 15 degrees to 30 degrees.

[0052] Preferably, if Figures 4 to 6 As shown, the drying system of the present invention further includes a flushing mechanism, which can spray water toward the first filter device to flush the first filter device.

[0053] When there are a lot of lint on the first filter 62, water is supplied to the flushing mechanism, which sprays water onto the first filter 62 to flush away the lint on the first filter 62, thereby flushing the first filter 62. The flushed lint can flow back to the drying drum 2 along the drying air duct, or a drainage structure can be set in the drying air duct to discharge the flushed lint through the drainage structure.

[0054] It should be noted that, in actual applications, those skilled in the art may set the flushing mechanism on the drying air duct, or may set the flushing mechanism on the first filter rack 61, or may set the flushing mechanism as an independent water spraying component (such as a water spraying pipe, etc.), etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited within the scope of protection of the present invention.

[0055] Preferably, if Figure 5 and Figure 6 As shown, the flushing mechanism of the present invention includes a flushing chamber 611 and a water spray port 612 arranged on the top of the first filter frame 61 . The water spray port 612 is communicated with the flushing chamber 611 and is arranged toward the first filter 62 .

[0056] Exemplarily, a water inlet connector 613 is also provided on the first filter frame 61, one end of the water inlet connector 613 is connected to a water source (such as a faucet or a water tank, etc.) through a water inlet pipe, and the other end of the water inlet connector 613 is connected to a flushing chamber 611. When the first filter 62 needs to be cleaned, water is supplied to the flushing chamber 611 through the water source, and the water in the flushing chamber 611 is sprayed toward the first filter 62 through the water nozzle 612 to flush the lint on the first filter 62.

[0057] Preferably, if Figure 5 and Figure 6 As shown, the flushing chamber 611 extends along the length direction of the first filter screen 62 , and there are multiple water spraying ports 612 that are spaced apart along the length direction of the flushing chamber 611 .

[0058] Preferably, such as Figures 1 to 4 As shown, the drying system of the present invention further includes a second filter device. A first plug interface 411 is provided on the drying air duct, and a portion of the second filter device passes through the first plug interface 411 and extends into the drying air duct.

[0059] Among them, the second filter device is located downstream of the first filter device. The second filter device is used to perform secondary filtering on the airflow in the drying duct to intercept impurities such as lint carried by the airflow. By connecting the second filter device to the drying duct by plugging, when the second filter device needs to be cleaned, the second filter device can be pulled out from the drying duct, and then inserted into the drying duct from the first plug interface 411 after cleaning. The operation is very convenient.

[0060] 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 second filter device is parallel to the axial direction of the drying drum 2 of the washer-dryer, and the second filter device extends to the second plug interface 11 .

[0061] For example, the second plug-in port 11 is provided on the front panel of the housing 1 , and when the second filter device needs to be cleaned, the user can directly pull out the second filter device from the front panel.

[0062] Preferably, if Figures 1 to 4 As shown, the drying air duct of the present invention 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, and 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 in the first drying air duct 41, and the first filter device is installed in the first drying air duct 41.

[0063] 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 crosswise, and the angle between the two is 90°. In this way, the drying air duct occupies less space and the layout is more optimized.

[0064] Preferably, if Figures 1 to 4 As shown, the second filtering device of the present application includes a housing 33 and a filtering assembly mounted on the housing 33 , and the filtering assembly can move relative to the housing 33 along the length direction of the housing 33 .

[0065] The outer shell 33 is fixedly installed between the drying duct and the housing 1. Specifically, the outer shell 33 is fixedly installed between the first drying duct 41 and the housing 1. The two ends of the outer shell 33 are respectively connected to the first plug port 411 on the first drying duct 41 and the second plug port 11 on the housing 1. A portion of the filter assembly extends through the first plug port 411 into the drying duct, specifically into the first drying duct 41. The filter assembly extends to the second plug port 11 of the housing 1. When the second filter device needs to be cleaned, it is only necessary to pull out the filter assembly without removing the outer shell 33 of the second 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.

[0066] It should be noted that the provision of the housing 33 is not essential, and those skilled in the art may also cancel the provision of the housing 33 according to actual conditions in actual applications.

[0067] Preferably, if Figure 4 and Figure 7 As shown, the filter assembly of the present invention includes a pull-out bracket 31 , a second filter screen frame 32 installed on the pull-out bracket 31 , and a second filter screen (not shown in the figure) installed on the second filter screen frame 32 .

[0068] Among them, the pull-out 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 pull-out bracket 31 and the second filter rack 32 are distributed along the length direction of the shell 33. The extension directions of the pull-out bracket 31 and the second filter rack 32 are parallel to the axial direction of the drying drum 2 of the washer-dryer. The pull-out bracket 31 extends to the second plug interface 11 of the box body 1, and the second filter rack 32 and the second filter pass through the first plug interface 411 and extend into the drying air duct. Specifically, the second filter rack 32 and the second filter pass through the first plug interface 411 and extend into the first drying air duct 41.

[0069] It should be noted that, in actual applications, those skilled in the art may extend the entire second filter holder 32 into the first drying duct 41, or may extend only the portion of the second filter holder 32 with the filter installed thereon, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be limited to the scope of protection of the present invention. Of course, the present invention preferably extends only a portion of the second filter holder 32 into the first drying duct 41.

[0070] In addition, it should be noted that the provision of the pull-out bracket 31 is not necessary, and those skilled in the art may cancel the provision of the pull-out bracket 31 according to specific circumstances in actual applications.

[0071] Preferably, if Figures 7 to 9 As shown, the second filter frame 32 of the present invention is detachably fixedly connected to the pull-out bracket 31 .

[0072] When the second filter needs to be cleaned, first pull out the pull-out bracket 31 from the box body 1. When the outer end of the second filter frame 32 moves to the outside of the box body 1 with the pull-out bracket 31, disassemble the pull-out bracket 31 from the second filter frame 32, and then continue to pull the second filter frame 32 until the second filter is pulled out. In this way, when disassembling the second filter device, the required horizontal space is smaller, disassembly is more convenient, and it is convenient to arrange the washer-dryer.

[0073] For example, Figure 7 As shown, the left end of the pull-out bracket 31 along its length direction is detachably fixedly connected to the right end of the second filter frame 32 along its length direction.

[0074] Preferably, the mesh number of the first filter 62 is smaller than the mesh number of the second filter.

[0075] Among them, the air flow in the first drying duct 41 first flows through the first filter 62 and then flows through the second filter. The mesh number of the first filter 62 is smaller than the mesh number of the second filter. For example, the mesh number of the first filter 62 can be set between 40 and 80, and the mesh number of the second filter can be set between 80 and 160.

[0076] Preferably, if Figure 7 and Figure 8 As shown, a lint accommodating chamber 321 is provided on the second filter screen frame 32 of the present invention. The lint accommodating chamber 321 is located upstream of the second filter screen and can accommodate lint intercepted by the second filter screen.

[0077] By providing a lint accommodating chamber 321 on the second filter frame 32 to collect the filtered lint, when the second filter and the second filter frame 32 are pulled out of the drying duct, the lint can be easily pulled out along with the second filter frame 32, which helps to prevent the lint from being trapped in the drying duct. If the lint is trapped in the drying duct, the lint will adhere to the second filter during the next drying, resulting in the need to frequently clean the filter, seriously affecting the user's experience. This is especially true when drying woolen clothes, which have a large amount of lint. If the lint accommodating chamber 321 is not provided, the second filter needs to be cleaned after each drying. If the second filter is not cleaned, a large amount of wool lint will accumulate in the drying duct. When the second filter is cleaned, most of the wool lint will be blocked in the drying duct. If the lint accommodating chamber 321 is provided, the use time of the second filter device can be greatly extended, the number of times the user cleans the filter is reduced, and the user experience is greatly improved.

[0078] Preferably, the depth of the lint accommodating cavity 321 is 5 to 15 mm.

[0079] For example, those skilled in the art may set the depth of the lint accommodating cavity 321 to 5 mm, 7 mm, 9 mm, 10 mm, 12 mm, 14 mm or 15 mm, etc., and further preferably to 10 mm.

[0080] The depth of the lint accommodating chamber 321 refers to the dimension along the thickness direction of the second filter frame 32 , or can also be understood as the dimension along the flow direction of the airflow.

[0081] Preferably, if Figure 7 As shown, the second filter frame 32 is provided with a door panel 323 at the position of the entrance of the lint accommodating chamber 321. The door panel 323 is pivotally connected to the second filter frame 32. The door panel 323 has an opening 3231 that allows airflow to pass through. The size of the opening 3231 is smaller than the size of the entrance of the lint accommodating chamber 321.

[0082] The inlet of the lint accommodating chamber 321 refers to the side away from the second filter screen. By setting a door panel 323 at the inlet, it is helpful to prevent the lint in the lint accommodating chamber 321 from escaping from the inlet of the lint accommodating chamber 321.

[0083] Exemplarily, the first end of the door panel 323 along its length direction is pivotally connected to the first end of the second filter frame 32 along its length direction. When it is necessary to clean the lint in the lint accommodating chamber 321, the door panel 323 is rotated a certain angle (30 degrees or 60 degrees, etc.) relative to the second filter frame 32 to open the entrance of the lint accommodating chamber 321, thereby facilitating the cleaning of the lint in the lint accommodating chamber 321.

[0084] Preferably, if Figure 7 As shown, a strip rib (not shown) is provided on the door panel 323 , and the strip rib extends from one end of the opening 3231 to the other end of the opening 3231 .

[0085] By providing a strip rib in the opening 3231 of the door panel 323 , it is more advantageous to prevent the wire scraps in the wire scrap accommodating chamber 321 from escaping from the entrance of the wire scrap accommodating chamber 321 .

[0086] The strip ribs may extend along the length direction of the opening 3231 , or along the width direction of the opening 3231 , or the strip ribs may be provided along both the length direction and the width direction of the opening 3231 .

[0087] Preferably, if Figures 7 to 9 As shown, the second filtering device of the present invention also includes a locking pin 34, which is installed on the pull-out bracket 31. The locking pin 34 is provided with a first locking structure 341, and the second filter frame 32 is provided with a second locking structure 322. When the locking pin 34 is in the locked position, the first locking structure 341 cooperates with the second locking structure 322 to lock the second filter frame 32 to the pull-out bracket 31. When the locking pin 34 is in the unlocked position, the first locking structure 341 is separated from the second locking structure 322, so that the second filter frame 32 of the second filter frame 32 can be removed from the pull-out bracket 31.

[0088] The utility model locks the pull-out bracket 31 and the second filter frame 32 through the locking pin 34. When the pull-out bracket 31 and the second filter frame 32 need to be disassembled, the locking pin 34 can be unlocked.

[0089] It should be noted that the present invention does not limit the specific structural form of the first locking structure 341 and the second locking structure 322. For example, the first locking structure 341 and the second locking structure 322 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, etc.

[0090] Preferably, if Figure 8 and Figure 9 As shown, the first locking structure 341 is a locking hook, and the second locking structure 322 is a locking opening adapted to the locking hook, and a portion of the locking hook can be inserted into the locking opening.

[0091] For example, Figure 8 and Figure 9As shown, the locking pin 34 is vertically mounted on the pull-out bracket 31. The locking hook provided on the locking pin 34 is upwardly positioned. There are two locking hooks spaced apart along the axis of the locking pin 34. The second filter holder 32 is correspondingly provided with two locking openings. The locking hooks are located below the locking openings. When the locking hooks are inserted into the locking openings, the pull-out bracket 31 and the second filter holder 32 are locked. When the pull-out bracket 31 and the second filter holder 32 need to be disassembled, the locking pin 34 is pressed downward to separate the locking hook from the locking opening. It should be noted that only one locking hook can be provided to cooperate with the locking opening.

[0092] Preferably, the second filtering device of the present invention also includes an elastic reset member (not shown in the figure) installed on the pull-out bracket 31, and the two ends of the elastic reset member are respectively connected to the pull-out bracket 31 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.

[0093] Exemplarily, the elastic reset member is arranged in the vertical direction and is located between the locking pin 34 and the inner bottom wall of the pull-out bracket 31. When the locking pin 34 is pressed downward, the elastic reset member is compressed. When the locking pin 34 is released, the elastic reset member can push up the locking pin 34, so that the locking pin 34 moves from the unlocked position to the locked position.

[0094] Preferably, the locking pin 34 is further provided with a receiving groove (not shown in the figures), and a portion of the elastic reset member is located in the receiving groove.

[0095] Exemplarily, the locking pin 34 is vertically arranged, the receiving groove extends along the axis of the locking pin 34 and extends to the bottom end of the locking pin 34 , and the elastic reset member is inserted into the receiving groove from the bottom end of the locking pin 34 .

[0096] It should be noted that the present invention does not limit the specific structural form of the elastic reset member. For example, the elastic reset member can be set as a spring or a rubber column, etc. Of course, the present invention preferably sets the elastic reset member as a spring.

[0097] Those skilled in the art will appreciate that although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are intended to be within the scope of this application and to form different embodiments. For example, in the claims of this application, any of the claimed embodiments may be used in any combination.

[0098] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
