DETAILED DESCRIPTION

[0072] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention will be further described below. It should be noted that the embodiments of the present invention and the features therein can be combined with each other without conflict.

[0073] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all the embodiments.

[0074] 1 to 17 , an embodiment of the present invention provides a clothes processing device, which may be, for example, a clothes dryer, a washer-dryer, or the like.

[0075] Specifically, the clothes processing device includes a box (not shown in the figure), a drying air duct 1 is provided in the box, and the drying air duct 1 has a ventilation part 11.

[0076] The clothing processing device may further include a clothing processing drum (not shown) and a heat pump heat exchange structure (not shown), both of which are disposed within the housing, and the inner cavity of the clothing processing drum is in communication with the drying duct 1, with at least a portion of the heat pump heat exchange structure disposed within the drying duct 1. The heat pump heat exchange structure may include a condenser and an evaporator, with a heat exchange medium (e.g., a refrigerant) flowing through the condenser and the evaporator.

[0077] In specific implementation, the low-temperature humid air in the clothing treatment drum can first enter the drying air duct 1 and exchange heat with the evaporator. The evaporator absorbs heat from the air to achieve air dehumidification. The dehumidified dry low-temperature air then passes through the condenser for heat exchange, thereby heating the air to form high-temperature dry air and then enters the clothing treatment drum to exchange heat with the clothes in the clothing treatment drum to achieve heating or drying of the clothes.

[0078] The first filter structure 2 is provided in the box body and can enter the drying air duct 1 through the ventilation part 11. The first filter structure 2 includes a filter body 21 and a gripping part 22 provided on the filter body 21, and the gripping part 22 can rotate relative to the filter body 21.

[0079] Exemplarily, the above-mentioned ventilation portion 11 can be specifically formed as the air inlet portion of the drying duct 1, by locating the first filtering structure 2 in the drying duct 1, for example, the first filtering structure 2 can be arranged on the upstream side of the evaporator. In this way, when the air in the clothing processing drum enters the drying duct 1 and there are debris such as dander in the air, the debris such as dander can be filtered and adsorbed to a certain extent by the first filtering structure 2, thereby improving the filtering effect of the debris such as dander, thereby avoiding to a certain extent the situation where debris such as dander clogs the drying duct 1 or other devices in the drying duct 1 (such as an evaporator or a condenser), thereby ensuring the smoothness of the air flow in the drying duct 1, and thereby improving the drying effect of the clothing processing equipment.

[0080] The clothes processing device provided in this embodiment is provided with a first filter structure 2 in a housing so that the first filter structure 2 can enter the drying duct 1 through the ventilation portion 11 of the drying duct 1. The first filter structure 2 includes a filter body 21 and a gripping portion 22 provided on the filter body 21, and the gripping portion 22 is rotatable relative to the filter body 21. With this arrangement, the first filter structure 2 can filter and adsorb debris such as hair particles contained in the air in the drying duct 1 to a certain extent, thereby improving the filtering effect on the hair particles and the like, thereby preventing the hair particles and the like from clogging the drying duct 1 or other components in the drying duct 1 to a certain extent, ensuring the smoothness of the air flow in the drying duct 1, thereby improving the drying effect of the clothes processing device, and also extending the service life of the clothes processing device to a certain extent. At the same time, by arranging a holding portion 22 on the filter body 21, the convenience of taking and placing the first filter structure 2 can be improved to a certain extent. Since the holding portion 22 can be rotated relative to the filter body 21, the position and posture of the holding portion 22 relative to the filter body 21 can be adjusted according to actual needs, thereby further improving the convenience of taking and placing the first filter structure 2, making it more convenient to use.

[0081] In some embodiments, as shown in Figures 11 to 16 , a front support 10 and a base 20 are provided in the cabinet. The front support 10 is located at the front side of the cabinet, and the base 20 is located below the front support 10 . The front support 10 and the base 20 define at least a portion of a drying duct 1 , and a ventilation portion 11 is provided on the front support 10 .

[0082] For example, the laundry processing drum can be disposed above the base 20 and located on the rear side of the front support 10. The rear side of the laundry processing drum has an air flow portion connected to the drying duct 1. During drying, the dotted arrows in FIG16 illustrate the flow of air within the drying duct 1. Specifically, the hot and humid air within the laundry processing drum enters the drying duct 1 from the laundry inlet of the laundry processing drum through the ventilation portion 11. After heat exchange with the heat pump heat exchange system in the drying duct 1, the air enters the laundry processing drum through the air flow portion to dry the clothes, thereby circulating. At the same time, the air entering the drying duct 1 is filtered by the first filter structure 2, which filters out debris such as hair in the air, thereby ensuring the drying effect.

[0083] 4 to 16 , the outer dimensions of the ventilation portion 11 are smaller than the cross-sectional dimensions inside the drying duct 1 . The outer dimensions of the filter body 21 are larger than those of the ventilation portion 11 .

[0084] The cross-section of the interior of the drying duct 1 is specifically a cross-section of the interior of the drying duct 1 on the XOY plane in Figures 11 to 13 and 16. Continuing to refer to Figures 11 to 13 and 16, it can be seen that the dimension of the ventilation portion 11 in the X direction is smaller than the dimension of the cross-section of the interior of the drying duct 1 in the X direction, and the dimension of the ventilation portion 11 in the Y direction is smaller than the dimension of the cross-section of the interior of the drying duct 1 in the Y direction.

[0085] The outer dimensions of the filter body 21 refer to the outer dimensions of the filter body 21 on the X1OY1 plane in Figure 4. As can be seen from Figures 4, 11 to 13, and 16, the dimension of the filter body 21 in the X1 direction is larger than the dimension of the ventilation portion 11 in the X direction, and the dimension of the filter body 21 in the Y1 direction is larger than the dimension of the ventilation portion 11 in the Y direction.

[0086] In order to facilitate the first filter structure 2 to enter the drying air duct 1 from the ventilation part 11, and when the first filter structure 2 is located in the drying air duct 1, it can better match the drying air duct 1, the first filter structure 2 can be tilted from the ventilation part 11 to enter the drying air duct 1, specifically referring to Figures 11 and 12, the first filter structure 2 is tilted at a certain angle relative to the XOY plane in Figures 11 and 12. At the same time, since the holding part 22 can be rotated relative to the filter body 21, for example, according to the size relationship between the outer contour dimensions of the ventilation part 11 and the outer contour dimensions of the filter body 21, the angle of the holding part 22 relative to the filter body 21 is adaptively adjusted so that the first filter structure 2 can smoothly extend from the ventilation part 11 into the drying air duct 1.

[0087] At the same time, since the outer contour size of the filter body 21 is larger than the outer contour size of the ventilation part 11, when the first filter structure 2 is placed in place in the drying air duct 1, it can further improve the sealing performance between the filter body 21 and the inner wall of the drying air duct 1 to a certain extent, thereby helping to improve the filtering effect of debris such as hair in the air.

[0088] Specifically, referring to Figures 13 to 17 , when the first filter structure 2 is placed in place in the drying duct 1 , for example, the filter body 21 can be placed horizontally to effectively filter the air flowing vertically in the drying duct 1 .

[0089] 7 to 10 , a rotation angle limiting structure 3 is provided between the filter body 21 and the grip portion 22 . The rotation angle limiting structure 3 is used to limit the rotation angle of the grip portion 22 relative to the filter body 21 .

[0090] By setting up the rotation angle limiting structure 3, the convenience of taking and placing the first filter structure 2 is further improved, and it can to a certain extent avoid the situation where the gripping portion 22 excessively rotates and interferes with other structures. It can also avoid the situation where the gripping portion 22 blocks the filter body 21 when the first filter structure 2 is placed in the drying air duct 1, further ensuring the filtering effect on the air.

[0091] In some embodiments, as shown in Figures 7 to 10, the rotation angle limiting structure 3 includes a first limiting surface 31 and a second limiting surface 32 provided on the filter body 21, and the first limiting surface 31 and the second limiting surface 32 are respectively provided on both sides of the rotation axis of the gripping portion 22 and the filter body 21.

[0092] The first limiting surface 31 is used to stop the grip portion 22 when the grip portion 22 rotates clockwise relative to the filter body 21 to a positive limit angle. The second limiting surface 32 is used to stop the grip portion 22 when the grip portion 22 rotates counterclockwise relative to the filter body 21 to a negative limit angle. The clockwise direction specifically refers to the S direction shown in Figures 6 and 9, and the counterclockwise direction specifically refers to the N direction shown in Figures 6 and 9.

[0093] In this way, through the cooperation of the first limiting surface 31 and the second limiting surface 32, the rotation angle of the gripping portion 22 relative to the filter body 21 is limited. The rotation angle limiting structure 3 has a simple structure and a good limiting effect.

[0094] In some embodiments, as shown in FIG. 1 to FIG. 10 , the angle between the grip portion 22 and the filter body 21 ranges from 60° to 150°.

[0095] This arrangement can not only avoid to a certain extent the situation where the holding portion 22 blocks the filter body 21 when the first filter structure 2 is placed in the drying air duct 1, thereby ensuring the filtering effect, but also avoid the situation where the holding portion 22 rotates excessively and interferes with other components.

[0096] 1 to 9 , the filter body 21 includes a base frame 211 and a filter element 212 disposed on the base frame 211. The gripping portion 22 is connected to the base frame 211 and is rotatable relative to the base frame 211.

[0097] With this arrangement, the filter element 212 can be fixed and supported to a certain extent by the base frame 211. Compared with the solution of setting the gripping portion on the filter element, by connecting the gripping portion 22 to the base frame 211, the convenience of taking the first filter structure 2 is improved, and the stability of the filter element 212 can be ensured to a certain extent, thereby ensuring a good filtering effect of the filter element 212.

[0098] In some embodiments, as shown in Figures 1 to 9, the grip portion 22 is disposed on the edge of the base frame 211. This arrangement allows the first filter structure 2 to be gripped for easy handling while also preventing the grip portion 22 from interfering with the filter element 212 and affecting the filtering effect, thereby ensuring the filtering effect on debris such as hair and improving the drying effect.

[0099] In some embodiments, the filter element 212 is a filter sponge. In this way, the filter element 212 has a simple structure and can filter debris and other debris well, ensuring a drying effect.

[0100] Of course, in other embodiments, the filter element 212 may also be a filter net, etc.

[0101] In some embodiments, when the ventilation portion 11 is specifically formed as an air inlet portion, the filter element 212 is located on a side of the base frame 211 facing the ventilation portion 11 .

[0102] That is to say, the air enters the drying duct 1 through the ventilation part 11, the filter element 212 is located on the windward side of the drying duct 1, and the base frame 211 is located on the leeward side. Through this arrangement, the filter element 212 can filter the air in a timely and effective manner, further improving the filtering effect, and can ensure that the base frame 211 effectively supports the filter element 212.

[0103] 1 , the bottom frame 211 has a concave cavity 2111 , and a wind-passing area 2112 is formed on the bottom wall of the concave cavity 2111 . The filter element 212 is located in the concave cavity 2111 .

[0104] With this arrangement, the filter element 212 can be limited to a certain extent by the concave cavity 2111, thereby improving the stability of the filter element 212 on the base frame 211, thereby improving the filtering effect.

[0105] In some embodiments, as shown in FIG. 1 and FIG. 2 , a support portion 2113 is provided on the cavity wall of the cavity 2111 along the circumference of the base frame 211 , and the support portion 2113 is used to support the filter element 212 .

[0106] By providing the support portion 2113 , stable support for the filter element 212 is achieved, thereby improving the stability of the filter element 212 and further enhancing the filtering effect.

[0107] For example, the support portion 2113 may be a support rib, a support protrusion, etc. The support portion 2113 may be extended along the entire circumference of the base frame 211 .

[0108] In some embodiments, as shown in Figures 4 to 9 , the top surface of the filter element 212 does not protrude from the top surface of the base frame 211. This arrangement can improve the aesthetic appearance of the first filter structure 2 to a certain extent, and can also prevent interference between the filter element 212 and external structures to a certain extent, thereby ensuring the stability of the filter element 212.

[0109] In some embodiments, the outer contour of the filter element 212 is adapted to the shape of the cavity 2111. This arrangement can further enhance the limiting effect of the base frame 211 on the filter element 212, thereby increasing the stability and reliability of the filter element 212.

[0110] 1 to 9 , the filter body 21 further comprises a cover plate 213 disposed on the bottom frame 211 . The cover plate 213 is connected to the bottom frame 211 to confine the filter element 212 between the bottom frame 211 and the cover plate 213 .

[0111] Such an arrangement can further improve the stability of the arrangement of the filter element 212, which is beneficial to ensuring the filtering effect of the filter element 212 and further improving the drying effect.

[0112] Of course, in other embodiments, the gripping portion 22 may also be disposed on the cover plate 213 .

[0113] In some embodiments, as shown in Figures 1 to 9, a first clamping portion 214 extending toward the cover plate 213 is provided on the base frame 211, a second clamping portion 215 that can be engaged with the first clamping portion 214 is provided on the cover plate 213, and a position of the filter element 212 corresponding to the first clamping portion 214 has an avoidance hole 2121 for the first clamping portion 214 to pass through.

[0114] In this way, the connection between the base frame 211 and the cover plate 213 is achieved through the engagement of the first clamping portion 214 and the second clamping portion 215. On the one hand, the connection between the base frame 211 and the cover plate 213 is convenient and does not require the intervention of third-party tools, and the assembly efficiency of the two is high; on the other hand, the above arrangement also realizes a detachable connection between the base frame 211 and the cover plate 213, so that when one of the base frame 211 and the cover plate 213 is damaged, only the damaged component needs to be replaced, which avoids the scrapping of the base frame 211 and the cover plate 213 as a whole to a certain extent, and reduces the maintenance cost to a certain extent.

[0115] In addition, by providing the above-mentioned avoidance hole 2121 on the filter element 212, while achieving the engagement between the base frame 211 and the cover plate 213, the filter element 212 can also be limited to a certain extent by the first clamping portion 214, thereby further ensuring the stability of the filter element 212 and improving the filtering effect.

[0116] In some embodiments, as shown in Figures 1 and 2, the first engaging portion 214 includes at least two elastic arms 2141. One end of each elastic arm 2141 is connected to the base frame 211, and the other end of each elastic arm 2141 extends toward the cover plate 213. The at least two elastic arms 2141 are circumferentially arranged and enclose a resilient engaging space, and the second engaging portion 215 can enter and engage in the resilient engaging space.

[0117] With this arrangement, when each elastic arm 2141 moves in a direction away from each other under the action of an external force, the second clamping portion 215 extends into the elastic clamping space, and when the external force disappears, each elastic arm 2141 moves in a direction close to each other to clamp the second clamping portion 215 in the elastic clamping space, thereby realizing the connection between the cover plate 213 and the base frame 211 through the clamping cooperation of the first clamping portion 214 and the second clamping portion 215, and the connection is convenient.

[0118] 1 and 2 , the second clamping portion 215 includes a clamping column disposed on the cover plate 213 and extending toward the base frame 211. This configuration simplifies the structure of the second clamping portion 215 and facilitates molding and configuration.

[0119] In other implementations, the second clamping portion 215 may also be a clamping block, etc.

[0120] Of course, in other embodiments, one of the first clamping portion 214 and the second clamping portion 215 may be a buckle, and the other of the first clamping portion 214 and the second clamping portion 215 may be a hole for the buckle to extend into and engage with.

[0121] In some embodiments, as shown in FIG. 1 to FIG. 17 , a sealing portion 4 is provided on the outer peripheral side of the filter body 21 , and the sealing portion 4 is used to seal with the inner wall of the drying air duct 1 .

[0122] This arrangement improves the sealing performance between the filter body 21 and the inner wall of the drying duct 1, and to a certain extent avoids the situation where debris such as hair in the drying duct 1 is not filtered by the filter body 21 but directly leaks between the filter body 21 and the inner wall of the drying duct 1, thereby further improving the filtering effect of debris such as hair in the air, further avoiding the blockage of the evaporator and condenser, and further improving the drying effect of the clothing processing equipment.

[0123] In some embodiments, as shown in Figures 1 to 9, the sealing portion 4 is specifically disposed on the base frame 211 along the outer periphery of the base frame 211. This arrangement ensures that the sealing portion 4 effectively seals the drying duct 1 while also preventing interference with the filter element 212 to a certain extent, thereby ensuring effective air filtering.

[0124] In some embodiments, the sealing portion 4 is a flexible sealing edge, such as a rubber sealing edge or a silicone sealing edge. This configuration effectively seals the drying duct 1, and the first filtering structure 2 is installed in the drying duct 1 with greater flexibility and ease of use. Furthermore, this configuration can prevent wear and tear on the sealing portion 4 to a certain extent, protecting the sealing portion 4 and extending its service life, further enhancing the filtering and drying effects.

[0125] In some embodiments, the sealing portion 4 is injection molded on the outer periphery of the base frame 211. This arrangement increases the overall structural strength of the sealing portion 4 and the base frame 211 and improves subsequent assembly efficiency to a certain extent.

[0126] Of course, the sealing portion 4 can also be sleeved on the outer peripheral side of the base frame 211 .

[0127] 1 to 5 , the gripping portion 22 is a flat handle, which facilitates gripping of the gripping portion 22 , improves the convenience of taking the first filter structure 2 , and makes assembly and replacement of the first filter structure 2 more convenient.

[0128] In some embodiments, as shown in FIG. 1 to FIG. 5 , the handle is provided with a hand-grip position 221 . This arrangement makes it easier for the user to grip the handle through the hand-grip position 221 , making it more convenient to use.

[0129] Exemplarily, the hand latch position 221 may be a hand latch groove, a hand latch hole, etc.

[0130] Of course, the gripping portion 22 can also be a drawstring or a pull cord.

[0131] In some embodiments, as shown in Figures 13 and 14 , a support structure 5 is provided within the drying duct 1 for supporting the first filter structure 2. This arrangement can, to a certain extent, provide good support for the first filter structure 2 within the drying duct 1, ensuring the stability of the first filter structure 2 within the drying duct 1 and facilitating the first filter structure 2's effective filtration of debris and other impurities in the air.

[0132] Illustratively, when the first filter structure 2 enters the drying air duct 1 through the ventilation portion 11 and the filter body 21 abuts against the support structure 5, the filter body 21 will rotate relative to the holding portion 22 under the supporting force of the support structure 5. For example, the filter body 21 can be rotated to be placed horizontally above the support structure 5, so that the filter body 21 can be stably supported by the support structure 5, so that the air in the drying air duct 1 can be filtered through the filter body 21 as much as possible.

[0133] In some embodiments, as shown in FIG. 13 and FIG. 14 , the support structure 5 includes support ribs 51 , and the edge of the base frame 211 is provided with a matching notch 2114 into which the support ribs 51 can extend.

[0134] By including the support ribs 51, the support structure 5 has a simple structure, is easy to manufacture and form, and effectively supports the first filter structure 2. Furthermore, the provision of the support ribs 51 can also support the drying duct 1 to a certain extent, ensuring the stability of the drying duct 1 and preventing deformation of the drying duct 1 to a certain extent, thereby ensuring smooth air flow and improving the drying effect.

[0135] By setting a matching notch 2114 on the edge of the base frame 211, the base frame 211 can be limited to a certain extent, further improving the supporting effect of the support structure 5 on the first filter structure 2, ensuring the stability and filtering effect of the first filter structure 2, and the drying effect of the clothing processing equipment is good.

[0136] Exemplarily, as shown in FIG. 1 and FIG. 4 , a guide slope may be provided on the inner wall of the matching notch 2114 , and the guide slope is used to guide the base frame 211 so that the support rib 51 extends into the matching notch 2114 .

[0137] Of course, as shown in Figure 14, the support structure 5 can also include a support shell 52 arranged in the drying air duct 1, for example, the support shell 52 is located on one side of the above-mentioned support rib 51, and the outer wall surface of the support shell 52 abuts against the base frame 211 to stably support the first filtering structure 2.

[0138] In some embodiments, as shown in FIG. 15 to FIG. 17 , a second filter structure 6 is further provided in the box body, and the second filter structure 6 is provided at the ventilation portion 11 .

[0139] In this way, through the cooperation of the first filter structure 2 and the second filter structure 6, the graded filtration of the air in the drying duct 1 can be improved. For example, when the ventilation part 11 is formed as an air inlet part, the air entering the drying duct 1 can be timely and effectively filtered at the first level through the second filter structure 6, and then the air can be filtered at the second level through the first filter structure 2, thereby further improving the filtering effect of debris such as hair in the air, and further avoiding the blockage of the evaporator, condenser, etc., thereby further improving the drying effect.

[0140] In some embodiments, as shown in FIG. 15 to FIG. 17 , the filter body 21 is located on the downstream side of the second filter structure 6 , and the gripping portion 22 is located between the second filter structure 6 and the inner wall of the drying air duct 1 .

[0141] In this way, the grip portion 22 is restrained by the second filter structure 6 and the inner wall of the drying duct 1, preventing the grip portion 22 from rotating and blocking the filter body 21, and facilitating the removal of the first filter structure 2. In addition, this arrangement effectively utilizes the space within the drying duct 1, facilitating the miniaturization of the drying duct 1, and thus making the entire clothing processing device smaller in size.

[0142] In some embodiments, as shown in Figures 1 to 17, a first axial hole is provided on the grip portion 22, and a second axial hole is provided on the filter body 21. The grip portion 22 is rotatably connected to the filter body 21 via a rotating shaft 7 passing through the first and second axial holes. This arrangement facilitates the rotational connection between the grip portion 22 and the filter body 21.

[0143] Of course, in some embodiments, the grip portion 22 and the filter body 21 can be rotatably connected via a flexible member. The flexible member can be, for example, a rubber member, a silicone member, etc., so that the rotational connection between the grip portion 22 and the filter body 21 is achieved through the deformation of the flexible member, which makes the connection between the two convenient.
