DETAILED DESCRIPTION

[0055] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the scheme of the embodiments of the present invention will be further described below. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the embodiments of the present invention, but the embodiments of the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0057] Reference Figures 1 to 13 As shown, this embodiment provides a clothes processing device. Exemplarily, the clothes processing device can be, for example, a clothes dryer, a washer-dryer, and the like.

[0058] Specifically, the clothes processing device includes a box body (not shown in the figure), and a drying air duct 1 is provided in the box body, and the drying air duct 1 has a ventilation part 11.

[0059] The clothing treatment device may further include a clothing treatment drum (not shown in the figure) and a heat pump heat exchange structure (not shown in the figure), both of which are arranged in the box, and the inner cavity of the clothing treatment drum is connected to the drying duct 1, and at least part of the heat pump heat exchange structure is arranged in the drying duct 1. The heat pump heat exchange structure may include a condenser and an evaporator, and a heat exchange medium (such as a refrigerant) flows in the condenser and the evaporator.

[0060] 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 is then passed 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.

[0061] Among them, a first filtering structure 2 is arranged inside the box body, and the first filtering structure 2 can enter the drying air duct 1 from the ventilation part 11. The first filtering structure 2 includes a filtering body 21 and a holding part 22 arranged on the filtering body 21. The holding part 22 is fixed relative to the filtering body 21 and is arranged at an angle with the filtering body 21.

[0062] It should be noted that the holding part 22 is arranged at an angle with the filtering body 21, which means that the holding part 22 and the filtering body 21 are not horizontally arranged, so as to facilitate the taking and placing of the first filtering structure 2 relative to the drying air duct 1.

[0063] Exemplarily, the ventilation part 11 can specifically be formed as the air inlet part of the drying air duct 1. By placing the first filtering structure 2 inside the drying air 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 laundry treatment drum enters the drying air duct 1 and there are impurities such as lint in the air, the first filtering structure 2 can filter and adsorb the impurities such as lint to a certain extent, improving the filtering effect on the lint and the like. Thus, to a certain extent, it avoids the situation that the drying air duct 1 or other devices (such as the evaporator or condenser) inside the drying air duct 1 are blocked by impurities such as lint, ensuring the smooth flow of air inside the drying air duct 1, and further improving the drying effect of the laundry treatment device.

[0064] Specifically, referring to Figures 9 to 13 As shown, when the first filtering structure 2 is placed in place inside the drying air duct 1, for example, the filtering body 21 can be placed horizontally to effectively filter the vertically flowing air inside the drying air duct 1.

[0065] For the laundry treatment device provided in this embodiment, by arranging the first filtering structure 2 inside the box body, the first filtering structure 2 can enter the drying air duct 1 from the ventilation part 11. The first filtering structure 2 includes a filtering body 21 and a holding part 22 arranged on the filtering body 21. The holding part 22 is fixed relative to the filtering body 21 and is arranged at an angle with the filtering body 21. With this arrangement, the first filtering structure 2 can filter and adsorb impurities such as lint in the air inside the drying air duct 1 to a certain extent, improving the filtering effect on the lint and the like. Thus, to a certain extent, it avoids the situation that the drying air duct 1 or other devices inside the drying air duct 1 are blocked by impurities such as lint, ensuring the smoothness of air flow inside the drying air duct 1, and further improving the drying effect of the laundry treatment device. Moreover, this can also extend the service life of the laundry treatment device to a certain extent. At the same time, by arranging the holding part 22 on the filtering body 21 and since the holding part 22 is arranged at an angle with the filtering body 21, the convenience of taking and placing the first filtering structure 2 can be improved to a certain extent, making it more convenient to use.

[0066] In some embodiments, as shown in reference to Figures 7 to 13 , there is a front support 10 and a base 20 inside the box. The front support 10 is located on the front side of the box, the base 20 is located below the front support 10, and at least part of the drying air duct 1 is defined between the front support 10 and the base 20. The ventilation part 11 is opened on the front support 10.

[0067] Exemplarily, a laundry treatment drum can be arranged above the base 20 and behind the front support 10, and an air passing part communicating with the drying air duct 1 is provided at the rear side of the laundry treatment drum. When drying, Figure 12 the dotted arrow in shows the flow direction of air in the drying air duct 1. Among them, the humid and hot air in the laundry treatment drum specifically enters the drying air duct 1 through the ventilation part 11 from the laundry loading opening of the laundry treatment drum. After heat exchange with the heat pump heat exchange system in the drying air duct 1, it enters the laundry treatment drum through the air passing part to dry the laundry, and this cycle continues. At the same time, the air entering the drying air duct 1 is filtered by the first filter structure 2, and the first filter structure 2 filters sundries such as lint in the air, thereby ensuring the drying effect.

[0068] In some embodiments, as shown in reference to Figures 1 to 6 , the range of the above-mentioned included angle is between 60° and 100°. Such a setting can, to a certain extent, avoid the situation where the first filter structure 2 enters the drying air duct 1 from the ventilation part 11 or interferes with components such as the inner wall of the drying air duct 1 when being taken out from the drying air duct 1, improving the convenience of taking and placing. Moreover, such a setting can, to a certain extent, avoid the situation where the holding part 22 blocks the filter body 21.

[0069] Exemplarily, as shown in reference to Figures 1 to 6 , for example, the included angle between the holding part 22 and the filter body 21 can be set at 90°, to further ensure the convenience of taking the first filter structure 2 and further ensure the filtering effect.

[0070] In some embodiments, as shown in reference to Figures 1 to 6 , the filter body 21 includes a bottom frame 211 and a filter element 212 arranged on the bottom frame 211. The holding part 22 is connected to the bottom frame 211 and is relatively fixed to the bottom frame 211, and an included angle is formed between the holding part 22 and the plane where the bottom frame 211 is located.

[0071] With such a setting, the bottom frame 211 can fix and support the filter element 212 to a certain extent. And compared with the solution of arranging the holding part on the filter element, by connecting the holding part 22 to the bottom frame 211, while improving the convenience of taking the first filter structure 2, it can also ensure the stability of the filter element 212 to a certain extent and ensure the good filtering effect of the filter element 212.

[0072] In some embodiments, the holding portion 22 and the chassis 211 are integrally formed. With this arrangement, the overall structural strength between the holding portion 22 and the chassis 211 is high, which is beneficial to improving the stability of the first filtering structure 2 for filtering air well and facilitating subsequent assembly.

[0073] In some embodiments, referring to Figure 1 and Figure 4 as shown, the holding portion 22 is disposed at the edge of the chassis 211. With this arrangement, while achieving the holding of the first filtering structure 2 for easy taking, it can also avoid the situation that the holding portion 22 interferes with the filter element 212 and affects the filtering effect to a certain extent, ensuring the filtering effect on debris such as lint, thereby improving the drying effect.

[0074] In some embodiments, the filter element 212 is a filter sponge. With this arrangement, the structure of the filter element 212 is simple, and it can achieve good filtering of debris such as lint to ensure the drying effect.

[0075] Of course, in other embodiments, the filter element 212 can also be a filter net or the like.

[0076] In some embodiments, referring to Figures 10 to 13 as shown, when the ventilation portion 11 is specifically formed as an air inlet portion, the filter element 212 is located on the side of the chassis 211 facing the ventilation portion 11.

[0077] That is to say, air enters the drying air duct 1 through the ventilation portion 11. The filter element 212 is located on the windward surface of the drying air duct 1, and the chassis 211 is located on the leeward surface. With this arrangement, the filter element 212 can filter air in a timely and effective manner, further improving the filtering effect and ensuring the effective support of the chassis 211 for the filter element 212.

[0078] In some embodiments, referring to Figures 1 to 4 as shown, the chassis 211 has a concave cavity 2111, and an air passing area 2112 is provided on the bottom wall of the concave cavity 2111. The filter element 212 is located in the concave cavity 2111.

[0079] With this arrangement, the concave cavity 2111 can limit the filter element 212 to a certain extent, improving the stability of the filter element 212 on the chassis 211, thereby improving the filtering effect.

[0080] In some embodiments, referring to Figure 1 and Figure 2 as shown, a support portion 2113 is provided on the cavity wall of the concave cavity 2111 along the circumferential direction of the chassis 211, and the support portion 2113 is used to support the filter element 212.

[0081] By providing the support portion 2113, the stable support for the filter element 212 is achieved, improving the stability of the filter element 212 and further enhancing the filtering effect.

[0082] Exemplarily, the support portion 2113 can be, for example, support ribs, support protrusions, etc. Among them, the support portion 2113 can be arranged to extend along the entire circumferential direction of the chassis 211.

[0083] In some embodiments, referring to Figure 4 as shown, the top surface of the filter element 212 does not protrude beyond the top surface of the chassis 211. Such an arrangement can, to a certain extent, improve the aesthetic appearance of the first filtering structure 2, and can also, to a certain extent, avoid the interference between the filter element 212 and external structures, ensuring the stability of the filter element 212.

[0084] In some embodiments, referring to Figure 4 as shown, the outer contour shape of the filter element 212 is adapted to the shape of the concave cavity 2111. Such an arrangement can further improve the limiting effect of the chassis 211 on the filter element 212, making the stability and reliability of the filter element 212 higher.

[0085] In some embodiments, referring to Figures 1 to 6 as shown, the filter body 21 further includes a cover plate 213 covering the chassis 211. The cover plate 213 is connected to the chassis 211 to confine the filter element 212 between the chassis 211 and the cover plate 213.

[0086] Such an arrangement can further improve the stability of the setting of the filter element 212, is beneficial to ensuring the filtering effect of the filter element 212, and further improving the drying effect.

[0087] Of course, in some other embodiments, the holding portion 22 can also be provided on the cover plate 213.

[0088] In some embodiments, referring to Figures 1 to 6 as shown, the chassis 211 is provided with a first clamping portion 214 extending in the direction towards the cover plate 213, the cover plate 213 is provided with a second clamping portion 215 that can be engaged with the first clamping portion 214, and the position of the filter element 212 corresponding to the first clamping portion 214 has an avoidance hole 2121 through which the first clamping portion 214 can pass.

[0089] In this way, through the engagement of the first clamping portion 214 and the second clamping portion 215, the connection between the chassis 211 and the cover plate 213 is realized. On the one hand, the connection between the chassis 211 and the cover plate 213 is convenient and does not require the intervention of a third-party tool, and the assembly efficiency of the two is high. On the other hand, the above setting also realizes the detachable connection between the chassis 211 and the cover plate 213. When one of the chassis 211 and the cover plate 213 is damaged, only the damaged part needs to be replaced, which to a certain extent avoids the scrapping of the whole of the chassis 211 and the cover plate 213 and reduces the maintenance cost to a certain extent.

[0090] In addition, by providing the above-mentioned avoidance hole 2121 on the filter element 212, while realizing the engagement between the chassis 211 and the cover plate 213, the filter element 212 can also be limited to a certain extent by the first clamping portion 214, further ensuring the stability of the filter element 212 and improving the filtering effect.

[0091] In some embodiments, referring to Figure 1 and Figure 2 as shown, the first clamping portion 214 includes at least two elastic arms 2141. One end of each elastic arm 2141 is connected to the chassis 211, and the other end of each elastic arm 2141 extends in the direction of the cover plate 213. At least two elastic arms 2141 are circumferentially arranged and enclose an elastic engagement space, and the second clamping portion 215 can enter and engage in the elastic engagement space.

[0092] With this setting, when each elastic arm 2141 can move away from each other under the action of an external force, the second clamping portion 215 extends into the elastic engagement space, and when the external force disappears, each elastic arm 2141 moves towards each other to clamp the second clamping portion 215 in the elastic engagement space, so as to realize the connection between the cover plate 213 and the chassis 211 through the clamping cooperation of the first clamping portion 214 and the second clamping portion 215, and the connection is convenient.

[0093] In some embodiments, referring to Figure 1 and Figure 2 as shown, the second clamping portion 215 includes a clamping post provided on the cover plate 213 and extending towards the chassis 211. With this setting, the structure of the second clamping portion 215 is simple and convenient to be formed.

[0094] In other implementation manners, the second clamping portion 215 can also be a clamping block or the like.

[0095] Of course, in some other embodiments, one of the first clamping portion 214 and the second clamping portion 215 can be a buckle, and the other of the first clamping portion 214 and the second clamping portion 215 can be a card hole into which the buckle can extend and be matched and engaged.

[0096] In some embodiments, referring to Figures 4 to 12 as shown, the outer contour dimension of the ventilation part 11 is smaller than the cross-sectional dimension inside the drying air duct 1. The outer contour dimension of the filter body 21 is larger than the outer contour dimension of the ventilation part 11.

[0097] Wherein, the cross-section inside the drying air duct 1 is specifically the cross-section of the inside of the drying air duct 1 on the XOY plane in Figure 7 , Figure 8 , Figure 10 and Figure 12 . Continuing to refer to Figure 7 , Figure 8 , Figure 10 and Figure 12 , it can be seen that the dimension of the ventilation part 11 in the X direction is smaller than the dimension of the cross-section inside the drying air duct 1 in the X direction, and the dimension of the ventilation part 11 in the Y direction is smaller than the dimension of the cross-section inside the drying air duct 1 in the Y direction.

[0098] Wherein, the outer contour dimension of the filter body 21 refers to the outer contour dimension of the filter body 21 on the X1OY1 plane in Figure 4 . From Figure 4 , Figure 7 , Figure 8 , Figure 10 and Figure 12 , it can be seen that the dimension of the filter body 21 in the X1 direction is larger than the dimension of the ventilation part 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 part 11 in the Y direction.

[0099] In order to facilitate the entry of the first filter structure 2 from the ventilation part 11 into the drying air duct 1 and enable the first filter structure 2 to better match the drying air duct 1 when it is located inside the drying air duct 1, the first filter structure 2 can be tilted to enter the drying air duct 1 from the ventilation part 11. Specifically, referring to Figure 7 and Figure 8 as shown, the first filter structure 2 is inclined at a certain angle with respect to the XOY plane in Figure 7 , Figure 8 , Figure 10 and Figure 12 . For example, the overall inclination angle of the first filter structure 2 can be flexibly adjusted manually during the taking process to change the position and attitude of the first filter structure 2. Moreover, since the holding part 22 and the filter body 21 are arranged at an angle and are not horizontally arranged, the first filter structure 2 can smoothly extend from the ventilation part 11 into the drying air duct 1.

[0100] Meanwhile, since the outer contour size of the filter body 21 is larger than that of the ventilation part 11, when the first filter structure 2 is properly placed in the drying air duct 1, the sealing performance between the filter body 21 and the inner wall of the drying air duct 1 can be further improved to a certain extent, which is beneficial to improving the filtering effect on debris such as lint in the air.

[0101] In some embodiments, referring to Figures 1 to 6 and Figure 13 as shown, a sealing portion 3 is provided on the outer peripheral side of the filter body 21, and the sealing portion 3 is used for sealing cooperation with the inner wall of the drying air duct 1.

[0102] With this arrangement, the sealing performance between the filter body 21 and the inner wall of the drying air duct 1 is improved, and to a certain extent, the situation where debris such as lint in the drying air duct 1 leaks directly between the filter body 21 and the inner wall of the drying air duct 1 without passing through the filter body 21 is avoided. Thereby, the filtering effect on debris such as lint in the air can be further improved, the situation where the evaporator and condenser are blocked is further avoided, and the drying effect of the clothing treatment device is further improved.

[0103] In some embodiments, referring to Figures 1 to 6 and Figure 13 as shown, the sealing portion 3 is specifically provided on the chassis 211 along the outer peripheral side of the chassis 211. With this arrangement, while ensuring good sealing of the drying air duct 1 by the sealing portion 3, the situation where the sealing portion 3 interferes with the filter element 212 is avoided to a certain extent, ensuring the filtering effect on the air.

[0104] In some embodiments, the sealing portion 3 is a flexible sealing edge, such as a rubber sealing edge or a silicone sealing edge. With this arrangement, the sealing portion 3 has a good sealing effect on the drying air duct 1, and the first filter structure 2 has good flexibility and high smoothness during installation in the drying air duct 1, which is convenient for use. Moreover, this can also avoid the situation where the sealing portion 3 is worn and damaged to a certain extent, protect the sealing portion 3, extend the service life of the sealing portion 3, and further improve the filtering effect and the drying effect.

[0105] In some embodiments, the sealing portion 3 is formed on the outer peripheral side of the chassis 211 by injection molding. With this arrangement, the overall structural strength of the sealing portion 3 and the chassis 211 is high, and this can also improve the subsequent assembly efficiency to a certain extent.

[0106] Of course, the sealing portion 3 can also be sleeved on the outer peripheral side of the chassis 211.

[0107] In some embodiments, referring to Figures 1 to 6 and Figure 13As shown, the holding part 22 is a planar handle. Such a setting facilitates the grasping of the holding part 22, improves the convenience of taking the first filtering structure 2, and makes the assembly and replacement of the first filtering structure 2 more convenient.

[0108] In some embodiments, referring to Figures 1 to 5 As shown, there is a handhold position 221 on the handle. Such a setting facilitates the user to hold the handle through the handhold position 221, making it more convenient to use.

[0109] Exemplarily, the handhold position 221 can be a handhold groove, a handhold hole, etc.

[0110] Of course, the holding part 22 can also be a pull rope or a pull ring, etc.

[0111] In some embodiments, referring to Figures 9 to 11 As shown, a support structure 4 for supporting the first filtering structure 2 is provided in the drying air duct 1. Such a setting can, to a certain extent, achieve good support for the first filtering structure 2 in the drying air duct 1, ensure the stability of the first filtering structure 2 in the drying air duct 1, and is beneficial to ensuring good filtering of debris such as lint in the air by the first filtering structure 2.

[0112] In some embodiments, referring to Figures 1 to 4 and Figure 10 and Figure 11 As shown, the support structure 4 includes support ribs 41, and a mating notch 2114 into which the support ribs 41 can extend is provided at the edge of the chassis 211.

[0113] By making the support structure 4 include support ribs 41, the structure of the support structure 4 is simple, easy to fabricate and form, and has a good support effect on the first filtering structure 2. In addition, the setting of the support ribs 41 can also support the drying air duct 1 to a certain extent, ensure the stability of the drying air duct 1, and avoid the deformation of the drying air duct 1 to a certain extent, which is beneficial to ensuring the smoothness of air flow and improving the drying effect.

[0114] By providing the mating notch 2114 at the edge of the chassis 211, the chassis 211 can be limited to a certain extent, further improving the support effect of the support structure 4 on the first filtering structure 2, ensuring the stability and filtering effect of the first filtering structure 2, and achieving a good drying effect of the laundry treatment device.

[0115] Exemplarily, referring to Figure 1 and Figure 4 As shown, for example, a guiding inclined surface can be provided on the inner wall of the mating notch 2114, and the guiding inclined surface is used to guide the chassis 211 so as to facilitate the extension of the support ribs 41 into the mating notch 2114.

[0116] Of course, referring toFigure 11 As shown, the support structure 4 may further include a support housing 42 disposed on one side inside the drying air duct 1. For example, the support housing 42 is located on one side of the above-mentioned support rib 41, and the outer wall surface of the support housing 42 abuts against the chassis 211 to stably support the first filter structure 2.

[0117] In some embodiments, referring to Figures 9 to 13 As shown, a second filter structure 5 is further disposed inside the box body, and the second filter structure 5 is disposed at the ventilation part 11.

[0118] With such an arrangement, through the cooperation of the first filter structure 2 and the second filter structure 5, the air in the drying air duct 1 can be filtered in stages. For example, when the ventilation part 11 is formed as an air inlet part, the second filter structure 5 can timely and effectively perform a primary filter on the air entering the drying air duct 1, and then the first filter structure 2 performs a secondary filter on the air, thereby further improving the filtering effect on debris such as lint in the air, and further avoiding the occurrence of blockages in the evaporator, condenser, etc., so that the drying effect is further improved.

[0119] In some embodiments, referring to Figures 9 to 13 As shown, the filter body 21 is located on the downstream side of the second filter structure 5, and the holding part 22 is located between the second filter structure 5 and the inner wall of the drying air duct 1.

[0120] In this way, the holding part 22 is limited by the second filter structure 5 and the inner wall of the drying air duct 1, improving the overall stability of the first filter structure 2 and facilitating the removal of the first filter structure 2. In addition, with such an arrangement, the space inside the drying air duct 1 is effectively utilized, facilitating the miniaturization of the drying air duct 1, and further enabling the entire clothing treatment device to develop in the direction of small volume.
