Detailed implementation manners

[0060] In order to more clearly understand the above objects, features and advantages of the embodiments of the present invention, the solutions of the embodiments of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0061] In the following description, many specific details are set forth in order to fully understand the embodiments of the present invention, but the embodiments of the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all the embodiments.

[0062] Referring to Figures 1 to 15 As shown, this embodiment provides a clothing treatment device. Exemplarily, the clothing treatment device can be, for example, a dryer, a washing and drying integrated machine, etc.

[0063] Specifically, the clothing treatment 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.

[0064] Among them, the clothing treatment device may further include a clothing treatment cylinder (not shown in the figure) and a heat pump heat exchange structure (not shown in the figure). The clothing treatment cylinder and the heat pump heat exchange structure are both provided in the box body, and the inner cavity of the clothing treatment cylinder is communicated with the drying air duct 1, and at least part of the heat pump heat exchange structure is provided in the drying air duct 1. Among them, the heat pump heat exchange structure may include a condenser and an evaporator, and a heat exchange medium (such as refrigerant) flows in the condenser and the evaporator.

[0065] Among them, a filter 3 is provided at the ventilation part 11, and the filter 3 filters debris such as lint in the air flowing between the drying air duct 1 and the clothing treatment cylinder.

[0066] In specific implementation, the low-temperature and humid air in the laundry drum can first enter the drying air duct 1, exchange heat with the evaporator, and the evaporator absorbs heat from the air to achieve air dehumidification. The dehumidified dry and low-temperature air then exchanges heat through the condenser, thereby heating the air to form high-temperature and dry air and entering the laundry drum, where it exchanges heat with the laundry in the laundry drum to achieve heating or drying of the laundry. Filtering the air through the filter 3 can, to a certain extent, avoid the situation where lint clogs the drying air duct 1 or affects the components in the drying air duct 1.

[0067] Among them, a filtering structure 2 is further provided in the box body. A connecting member 4 for connecting with the filter 3 is provided on the filtering structure 2, and the filtering structure 2 can enter the drying air duct 1 from the ventilation part 11.

[0068] Exemplarily, the above-mentioned ventilation part 11 can specifically be formed as the air inlet part of the drying air duct 1. Through the above setting, at least part of the air can be hierarchically filtered through the filter 3 and the filtering structure 2 in sequence. For example, the filter 3 can perform timely and effective primary filtering on the air entering the drying air duct 1, and then the filtering structure 2 performs secondary filtering on the air, thereby avoiding, to a certain extent, the situation where lint and other debris in the air clog the drying air duct 1 or the structures in the drying air duct 1 (such as the evaporator, condenser, etc.), and further improving the drying effect.

[0069] The laundry treatment device provided in this embodiment, by providing the filtering structure 2 in the box body and providing the connecting member 4 on the filtering structure 2, enables the connecting member 4 to be used for connecting with the filter 3 at the ventilation part 11 of the drying air duct 1, and enables the filtering structure 2 to enter the drying air duct 1 from the ventilation part 11. With such a setting, through the cooperation of the filtering structure 2 and the filter 3, the air in the drying air duct 1 can be hierarchically double-filtered to a certain extent, thereby improving the filtering and adsorption effect on lint and other debris in the air, further avoiding the situation where lint and other debris clog the drying air duct 1 or other devices in the drying air duct 1, ensuring the smoothness of the air flow in 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, since the connecting member 4 for connecting with the filter 3 is provided on the filtering structure 2, that is, the filtering structure 2 can be connected to the filter 3 through the connecting member 4, so that the filtering structure 2 and the filter 3 can be connected as a whole and installed or detached from the drying air duct 1 together, so as to ensure good air filtration while improving the convenience and efficiency of the installation and disassembly of the filtering structure 2.

[0070] In some embodiments, referring to Figures 10 to 14As shown, the box body has a front support 10 and a base 20. The front support 10 is located at the front side of the box body, 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.

[0071] Exemplarily, the laundry treatment cylinder can be arranged above the base 20 and behind the front support 10. The rear side of the laundry treatment cylinder has an air passing part communicating with the drying air duct 1. When drying, Figure 14 the dotted arrow in shows the air flow direction in the drying air duct 1. Among them, the humid and hot air in the laundry treatment cylinder specifically enters the drying air duct 1 through the ventilation part 11 from the laundry inlet of the laundry treatment cylinder. After heat exchange with the heat pump heat exchange system in the drying air duct 1, it enters the laundry treatment cylinder 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 can be filtered through the filter 3 and the filtering structure 2 in sequence to filter sundries such as lint in the air, thereby ensuring the drying effect.

[0072] In some embodiments, referring to Figures 1 to 15 as shown, the connecting piece 4 has a clamping space 411. One side of the clamping space 411 facing the filter 3 has an opening 412 for the filter 3 to enter, so as to clamp the filter 3.

[0073] With such a setting, through the clamping of the connecting piece 4 and the filter 3, the connection between the filtering structure 2 and the filter 3 is realized, and the connection between the two is simple and convenient. Moreover, since the connecting piece 4 is clamped and fixed with the filter 3, to a certain extent, the detachable connection between the filtering structure 2 and the filter 3 is realized. No third-party tool is required for connection, and the connection is convenient. When one of the filtering structure 2 and the filter 3 is damaged, only the damaged part needs to be replaced, which avoids the scrapping of the whole of the filtering structure 2 and the filter 3 to a certain extent and reduces the maintenance cost.

[0074] In some embodiments, referring to Figure 1 、 Figure 3 and Figure 15 as shown, the connecting piece 4 is further provided with a positioning part 413 for positioning the filter 3.

[0075] With such a setting, through the positioning part 413, the connection stability and reliability between the connecting piece 4 and the filter 3 can be further improved to a certain extent, which is beneficial to ensuring the filtering effect of the filter 3 and the filtering structure 2, thereby ensuring the drying effect.

[0076] Exemplarily, referring to Figure 1 、 Figure 3 and Figure 15As shown, at least the portion of the filter 3 located within the clamping space 411 can be, for example, a hollow structure to ensure smooth air flow. To strengthen the structure of the filter 3, a clamping protrusion 31 can be provided on the filter 3, for example, to improve the structural strength of the filter 3 and ensure the filtering effect.

[0077] In some embodiments, referring to Figure 1 、 Figure 3 and Figure 15 as shown, the positioning portion 413 includes a clamping groove 2241 provided on the inner wall of the clamping space 411. The clamping groove 2241 is for the above-mentioned clamping protrusion 31 to extend into and engage with the clamping protrusion 31.

[0078] In this way, through the cooperation of the clamping groove 2241 and the clamping protrusion 31, the cooperation between the connecting member 4 and the filter 3 is realized. The structure is simple and convenient to use, and the positioning is reliable. Moreover, the clamping protrusion 31 used for strengthening the structure of the filter 3 is reasonably utilized to position the connecting member 4 and the filter 3. While ensuring the structural strength of the filter 3, it can also achieve reliable positioning of the connecting member 4 and the filter 3, further improving the filtering effect and the drying effect.

[0079] In some embodiments, referring to Figure 1 、 Figure 3 and Figure 15 as shown, the connecting member 4 includes two relatively arranged and connected elastic clamping arms 41. A clamping space 411 is jointly defined between the two elastic clamping arms 41.

[0080] With this setting, when the two elastic clamping arms 41 can move in a direction away from each other under an external force, the filter 3 extends into the clamping space 411. When the external force disappears, the two elastic clamping arms 41 move in a direction close to each other to clamp the filter 3 in the clamping space 411. That is, the filter 3 is reliably clamped through the elastic deformation of the elastic clamping arms 41. The clamping process is simple and convenient, and the clamping stability of the filter 3 is high, ensuring the reliable connection between the connecting member 4 and the filter 3.

[0081] In some embodiments, referring to Figure 1 、 Figure 3 and Figure 15 as shown, the inner cavity shape of the clamping space 411 is adapted to the shape of the filter 3. With this setting, the clamping effect on the filter 3 can be further improved, the connection stability between the filter 3 and the filtering structure 2 is improved, and the filtering effect and the drying effect are good.

[0082] In some embodiments, referring to Figure 1 and Figure 3As shown, a gripping portion 414 for gripping is further provided at the opening 412. With this arrangement, it is convenient to grip the connecting member 4 on the filter 3 through the gripping portion 414, making it more convenient to use.

[0083] Exemplarily, the gripping portion 414 can be, for example, a planar gripping plate, or can also be a gripping column, etc.

[0084] In some embodiments, referring to Figures 12 to 13 As shown, a support structure 5 for supporting the filter structure 2 is provided in the drying air duct 1. With this arrangement, it can achieve good support for the filter structure 2 in the drying air duct 1 to a certain extent, ensure the stability of the filter structure 2 in the drying air duct 1, and is beneficial to ensuring good filtration of debris such as lint in the air by the filter structure 2.

[0085] In some embodiments, referring to Figures 1 to 11 As shown, the filter structure 2 includes a first filter portion 21. The first filter portion 21 is rotatably connected to the connecting member 4.

[0086] With this arrangement, when installing the connected filter structure 2 and the filter 3, since the first filter portion 21 is rotatably connected to the connecting member 4, it is convenient to adjust the position and attitude of the first filter portion 21 relative to the filter 3, improving the convenience of the filter structure 2 entering the drying air duct 1, with high installation efficiency and good flexibility in use, and can also avoid interference between the filter structure 2 and the drying air duct 1 during installation to a certain extent.

[0087] Exemplarily, when the filter structure 2 enters the drying air duct 1 through the ventilation portion 11 and the filter structure 2 abuts against the above-mentioned support structure 5, the filter structure 2 will rotate to the proper position relative to the connecting member 4 under the supporting force of the support structure 5, for example, rotate to a horizontal attitude of the filter structure 2, so that as much air as possible in the drying air duct 1 passes through the filter structure 2 for filtration.

[0088] Exemplarily, referring to Figure 12 and Figure 13 As shown, the support structure 5 can include support ribs 51. In this way, the structure of the support structure 5 is simple, easy to manufacture and form, and has a good supporting effect on the filter structure 2. In addition, the setting of the support ribs 51 can also support the drying air duct 1 to a certain extent, ensure the stability of the drying air duct 1, avoid the deformation of the drying air duct 1 to a certain extent, and is beneficial to ensuring the smoothness of air flow and improving the drying effect.

[0089] Of course, referring to Figure 13As shown, the support structure 5 may further include a support housing 52 disposed in the drying air duct 1. For example, the support housing 52 is located on one side of the above-mentioned support rib 51, and the outer wall surface of the support housing 52 abuts against the filter structure 2 to stably support the filter structure 2.

[0090] In some embodiments, referring to Figures 1 to 11 As shown, there are two first filter parts 21. Both of the two first filter parts 21 are rotatably connected to the connecting member 4. The rotation axes of the two first filter parts 21 and the connecting member 4 are coaxially arranged, and the two first filter parts 21 are respectively arranged on both sides of the rotation axis so that the two first filter parts 21 can rotate towards each other or away from each other. Specifically, the direction of the rotation axis of the first filter part 21 and the connecting member 4 is Figure 1 、 Figure 8 and Figure 9 the X1-X1 direction shown.

[0091] With this setting, when the filter structure 2 is taken, both of the two first filter parts 21 can rotate relative to the connecting member 4. Referring to Figure 10 and Figure 11 As shown, for example, the two first filter parts 21 can be rotated to form an "eight" shape structure, thereby relatively reducing the size of the filter structure 2 in the Figures 10 to 12 and Figure 14 Y-Y direction shown, further improving the convenience of taking and placing the filter structure 2.

[0092] In some embodiments, referring to Figure 2 and Figure 4 As shown, the first filter part 21 includes a first filter element 210 and a first bracket 211. The first filter element 210 is arranged on the first bracket 211, and the first bracket 211 is rotatably connected to the connecting member 4.

[0093] With this setting, the first bracket 211 can fix and support the first filter element 210 to a certain extent. And compared with the solution of rotatably connecting the first filter element and the connecting member, by rotatably connecting the first bracket 211 and the connecting member 4, while improving the convenience of taking the filter structure 2, it can also ensure the stability of the first filter element 210 to a certain extent and guarantee the filtering effect of the first filter element 210.

[0094] In some embodiments, referring to Figure 2 and Figure 4 As shown, the first bracket 211 includes a first bottom frame 212 and a first top frame 213. The first top frame 213 is connected to the first bottom frame 212 to limit the first filter element 210 between the first top frame 213 and the first bottom frame 212.

[0095] With such a setting, the stability of the first filter element 210 can be further improved, which is beneficial to ensuring the filtering effect of the first filter element 210 and further improving the drying effect.

[0096] In some embodiments, referring to Figure 2 and Figure 4 as shown, a first clamping portion 2131 extending in the direction towards the first bottom frame 212 is provided on the first top frame 213, and the first clamping portion 2131 is used for clamping with the first bottom frame 212. A first avoidance hole 2101 for the first clamping portion 2131 to pass through is provided on the first filter element 210.

[0097] In this way, through the engagement of the first clamping portion 2131 and the first bottom frame 212, the connection between the first bottom frame 212 and the first top frame 213 is realized. On the one hand, the connection between the first bottom frame 212 and the first top frame 213 is convenient, and no third-party tool is required for intervention, and the assembly efficiency of the two is high; on the other hand, the above setting also realizes the detachable connection between the first bottom frame 212 and the first top frame 213, so that when one of the first bottom frame 212 and the first top frame 213 is damaged, only the damaged part needs to be replaced, which to a certain extent avoids the scrapping of the whole of the first bottom frame 212 and the first top frame 213 and reduces the maintenance cost to a certain extent.

[0098] In addition, by providing the first avoidance hole 2101 on the first filter element 210, while realizing the engagement between the first bottom frame 212 and the first top frame 213, the first filter element 210 can also be limited to a certain extent by the first clamping portion 2131, further ensuring the stability of the first filter element 210 and ensuring the filtering effect.

[0099] Of course, in some other embodiments, the first clamping portion can also be provided on the first bottom frame, and the first clamping portion extends in the direction towards the first top frame and can be clamped with the first top frame.

[0100] In some embodiments, referring to Figure 2 and Figure 4 as shown, first air passing areas 214 are provided on both the first top frame 213 and the first bottom frame 212. With such a setting, while ensuring the support and positioning of the first filter element 210 by the first top frame 213 and the first bottom frame 212, it can ensure that the first filter element 210 filters air well.

[0101] In some embodiments, referring to Figure 2 and Figure 4 as shown, the first filter element 210 is a filter sponge. With such a setting, the structure of the first filter element 210 is simple, and it can realize good filtering of debris such as lint, ensuring the drying effect.

[0102] Of course, in some other embodiments, the first filter element 210 may also be a filter mesh or the like, for example.

[0103] In some embodiments, referring to Figures 1 to 10 As shown, the projection of the first bracket 211 on the first filter element 210 is located within the area enclosed by the outer contour of the first filter element 210. With this setting, on the basis of enabling the first bracket 211 to support the first filter element 210, it is also possible to ensure to a certain extent the filtering area of the first filter element 210. When the first filter element 210 is placed in place in the drying air duct 1, the outer contour of the first filter element 210 fits as closely as possible to the inner wall of the drying air duct 1, so that as much air as possible in the drying air duct 1 passes through the first filter element 210, thereby achieving good filtration and further improving the filtration effect. Moreover, the stability of the first filter element 210 can be improved.

[0104] In addition, when the first filter element 210 is a filter sponge, since the filter sponge is a deformable flexible structure, with the above setting, while ensuring the filtering area of the first filter element 210, the filtering structure 2 has good flexibility and high smoothness when being taken out of the drying air duct 1, which is convenient for use. Moreover, this can also avoid to a certain extent the situation where the first filter element 210 is worn and damaged, protect the first filter element 210, extend the service life of the first filter element 210, and further improve the filtration effect and drying effect.

[0105] In some embodiments, referring to Figures 1 to 10 As shown, the filtering structure 2 further includes a second filtering part 22, and the second filtering part 22 is located beside the first filtering part 21. The second filtering part 22 is rotatably connected to the connecting member 4, and the rotation axis of the second filtering part 22 and the connecting member 4 intersects with the rotation axis of the first filtering part 21 and the connecting member 4. Among them, the rotation axis of the second filtering part 22 and the connecting member 4 is specifically Figure 1 、 Figure 8 and Figure 9 the Y1 - Y1 direction shown.

[0106] With this setting, the first filtering part 21 and the second filtering part 22 can rotate relative to the connecting member 4 along different rotation axes, so as to further adjust the position and posture of the filtering structure 2 relative to the filter 3. When the filtering structure 2 is taken out, the projection size of the filtering structure 2 in the Figures 10 to 12 and Figure 14 XOY direction shown can be reduced from different directions, further improving the convenience of taking out the filtering structure 2 from the ventilation part 11, and the taking - out efficiency is high.

[0107] In some embodiments, referring to Figure 2 and Figure 5As shown, the second filtering part 22 includes a second filter element 220 and a second bracket 221. The second filter element 220 is disposed on the second bracket 221, and the second bracket 221 is rotatably connected to the connecting member 4.

[0108] With such an arrangement, the second filter element 220 can be fixed and supported to a certain extent by the second bracket 221. And compared with the solution of rotatably connecting the second filter element to the connecting member, by rotatably connecting the second bracket 221 to the connecting member 4, while improving the convenience of taking the filtering structure 2, the stability of the second filter element 220 can be ensured to a certain extent, and the filtering effect of the second filter element 220 can be guaranteed.

[0109] In some embodiments, referring to Figure 2 and Figure 5 as shown, the second bracket 221 includes a second bottom frame 222 and a second top frame 223. The second top frame 223 is connected to the second bottom frame 222 to confine at least part of the second filter element 220 between the second top frame 223 and the second bottom frame 222.

[0110] With such an arrangement, the stability of the second filter element 220 can be further improved, which is beneficial to ensuring the filtering effect of the second filter element 220 and further improving the drying effect.

[0111] In some embodiments, referring to Figure 2 and Figure 5 as shown, a fixing portion 224 is provided on the second bracket 221. The fixing portion 224 is used to connect to the connecting member 4 when the second filter element 220 rotates to a preset angle.

[0112] In this way, the stability of the connection between the second filter element 220 and the connecting member 4 can be improved to a certain extent through the fixing portion 224, so as to ensure the posture of the second filter element 220 and further ensure the filtering effect.

[0113] Exemplarily, referring to Figures 10 to 15 as shown, when the filtering structure 2 abuts against the supporting structure 5 in the drying air duct 1, the second bracket 221 will rotate towards the direction close to the connecting member 4 under the supporting action of the supporting structure 5, and when rotating a preset angle, the second filtering part 22 can be fixed through the cooperation of the fixing portion 224 and the connecting member 4, ensuring the stability of the second filtering part 22.

[0114] In some embodiments, referring to Figure 2 and Figure 5 as shown, the fixing portion 224 is provided on the second bottom frame 222, and the fixing portion 224 is located between the rotation axis of the second bracket 221 and the connecting member 4 and the second top frame 223.

[0115] With such a setting, the second filter element 220 is positioned from different positions by the fixing part 224 and the second top bracket 223, further improving the stability of the second filter element 220. Moreover, to a certain extent, the situation where the connection between the fixing part 224 and the connecting member 4 interferes with the second top bracket 223 is avoided, making the connection between the fixing part 224 and the connecting member 4 convenient, thereby improving the stability of the second filter part 22.

[0116] In some embodiments, referring to Figure 2 and Figure 5 as shown, the fixing part 224 includes a clamping post provided on the second bracket 221. A clamping groove 2241 for clamping on the connecting member 4 is provided on the clamping post, and a second avoidance hole 2201 through which the clamping post can pass is provided on the second filter element 220.

[0117] With such a setting, the structure of the fixing part 224 is simple, and the clamping with the connecting member 4 is convenient. At the same time, by providing the second avoidance hole 2201 on the second filter element 220, while realizing the clamping of the second bracket 221 and the connecting member 4, the second filter element 220 can also be limited to a certain extent by the clamping post, further ensuring the stability of the second filter element 220 and ensuring the filtering effect.

[0118] Exemplarily, when it is necessary to take out the filtering structure 2 from the drying air duct 1, the filter 3 is pulled upward so that the filtering structure 2 and the filter 3 move upward synchronously. And during the upward movement, when the second filter part 22 (such as the second bracket 221) interferes with the inner wall of the drying air duct 1 or other structures in the drying air duct 1, the second bracket 221 will receive a downward force to disengage the fixing part 224 from the clamping with the connecting member 4 and rotate relative to the connecting member 4, thereby facilitating the taking out of the filtering structure 2 from the drying air duct 1.

[0119] In some embodiments, referring to Figure 2 and Figure 5 as shown, the second top bracket 223 is provided with a second clamping part 2231 extending in the direction towards the second bottom bracket 222, and the second clamping part 2231 is used for clamping with the second bottom bracket 222.

[0120] In this way, through the engagement between the second engaging portion 2231 and the second chassis 222, the connection between the second chassis 222 and the second top frame 223 is realized. On the one hand, the connection between the second chassis 222 and the second top frame 223 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 second chassis 222 and the second top frame 223, so that when one of the second chassis 222 and the second top frame 223 is damaged, only the damaged component needs to be replaced, which to a certain extent avoids the scrapping of the whole of the second chassis 222 and the second top frame 223 and reduces the maintenance cost to a certain extent.

[0121] Of course, in some other embodiments, the second engaging portion may also be provided on the second chassis and extend in the direction towards the second top frame and be engageable with the second top frame.

[0122] Exemplarily, for example, a third avoidance hole 2202 for the second engaging portion 2231 to pass through may be formed in the second filter element 220 to further position the second filter element 220, and the stability of the second filter element 220 is good.

[0123] In some embodiments, referring to Figure 2 and Figure 5 as shown, second air passing areas 225 are formed on both the second chassis 222 and the second top frame 223. With this setting, while ensuring that the second top frame 223 and the second chassis 222 support and position the second filter element 220, it can ensure that the second filter element 220 filters air well.

[0124] In some embodiments, referring to Figures 1 to 10 as shown, the second filter element 220 is a filter sponge. With this setting, the structure of the second filter element 220 is simple, and it can achieve good filtration of sundries such as lint and ensure the drying effect.

[0125] Of course, in some other embodiments, the second filter element 220 may also be a filter net or the like.

[0126] In some embodiments, referring to Figures 1 to 10As shown, the projection of the second bracket 221 on the second filter element 220 is located within the area enclosed by the outer contour of the second filter element 220. With this arrangement, while the second bracket 221 supports the second filter element 220, it can also ensure the filtering area of the second filter element 220 to a certain extent. When the second filter element 220 is placed in place in the drying air duct 1, the outer contour of the second filter element 220 can fit as closely as possible to the inner wall of the drying air duct 1, allowing as much air as possible in the drying air duct 1 to pass through the first filter element 210 and the second filter element 220, further improving the filtering effect, and this can also improve the stability of the second filter element 220.

[0127] In addition, when the second filter element 220 is a filtering sponge, since the filtering sponge is a deformable flexible structure, with the above arrangement, while ensuring the filtering area of the second filter element 220, it makes the filtering structure 2 flexible and smooth when being taken in and out of the drying air duct 1, facilitating use. Moreover, this can also avoid the situation where the second filter element 220 is worn and damaged to a certain extent, protecting the second filter element 220, extending the service life of the second filter element 220, and further improving the filtering effect and drying effect.

[0128] Exemplarily, referring to Figures 1 to 15 as shown, for example, the outer contour dimension of the ventilation part 11 can be made smaller than the cross-sectional dimension inside the drying air duct 1, and the outer contour dimension of the filtering structure 2 can be made larger than the outer contour dimension of the ventilation part 11.

[0129] Among them, the cross-section inside the drying air duct 1 specifically refers to the cross-section of the inside of the drying air duct 1 on the Figures 10 to 12 and Figure 14 XOY plane in Figures 10 to 12 and Figure 14 . Continuing to refer to

[0130] Specifically, the outer contour dimension of the filtering structure 2 refers to the outer contour dimension of the filtering structure 2 on the Figure 1 , Figure 8 and Figure 9 X1OY1 plane in Figure 1 , Figures 8 to 12 and Figure 14 . It can be seen from

[0131] To facilitate the installation of the filter 3 at the ventilation part 11 and enable the filter structure 2 and the filter 3 to enter the drying air duct 1 together from the ventilation part 11, and when the filter structure 2 is located in the drying air duct 1, it can better match the drying air duct 1. For example, the first filter part 21 and the second filter part 22 can both rotate a preset angle relative to the connecting member 4 so that the filter structure 2 enters the drying air duct 1 in a folded state. Specifically, refer to Figure 10 and Figure 11 As shown, since both the first filter part 21 and the second filter part 22 rotate relative to the connecting member 4 to make the filter structure 2 fold relatively, the position and attitude of the filter structure 2 are changed so that the filter structure 2 can smoothly extend from the ventilation part 11 into the drying air duct 1.

[0132] At the same time, since the outer contour size of the filter structure 2 is larger than that of the ventilation part 11, when the filter structure 2 is placed in place in the drying air duct 1, the sealing performance between the filter structure 2 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 impurities such as lint in the air.
