[0051] As described in the background, the laundry treating apparatus is an apparatus for performing various treatment operations on laundry. In the related art, the laundry treating apparatus having a drying function includes a drying module including a moisture absorbing and removing assembly including a moisture absorbing and removing member and a mounting case in which the moisture absorbing and removing member is installed, and a drying air duct in which the mounting case is installed. However, the above-described mounting method cannot provide stable constraint to the moisture absorbing and removing member, and thus the moisture absorbing and removing member is easily shaken or jumped due to the vibration of the entire drying module during transportation and use, thereby affecting the normal use of the drying module.

[0052] REFERENCE Figures 1 to 5To solve the above problems, according to an aspect of the present application, embodiments of the present application provide a drying module, which comprises a moisture absorbing and removing assembly 100 and a drying air duct 200, the moisture absorbing and removing assembly 100 comprises a moisture absorbing and removing piece 110 and a mounting shell 120, the moisture absorbing and removing piece 110 is arranged in the mounting shell 120, and the mounting shell 120 is arranged in the drying air duct 200; the drying module further comprises a limiting assembly for limiting the axial positioning of the moisture absorbing and removing piece 110.

[0053] In the embodiments of the present application, the drying module is used in a clothes treatment device, such as a clothes dryer. The drying module further comprises a base 400, the drying air duct 200 is arranged on the base 400 and is made of metal (such as galvanized steel plate) or plastic, and the shape and size thereof can be determined according to the actual requirements of the drying module, which is not limited herein. The moisture absorbing and removing piece 110 is arranged in the mounting shell 120 for absorbing moisture; the mounting shell 120 is arranged in the drying air duct 200. The limiting assembly is arranged on the mounting shell 120 and can be a mechanical limiting structure (such as a shaft shoulder and a shaft sleeve used in cooperation, a stop washer and a nut used in cooperation, a circlip or a check ring), an elastic limiting structure (such as a spring block or a rubber buffer limiting block) or a magnetic limiting structure.

[0054] In the present application, the limiting assembly arranged provides a stable blocking force for the moisture absorbing and removing piece 110 in the axial direction, so that the moisture absorbing and removing piece 110 can be limited from being displaced in the axial direction when subjected to external vibration (whether it is the bumping vibration in the transportation process or the vibration generated by the operation of the drying module itself in the use process), thereby reducing the possibility of the moisture absorbing and removing piece 110 being vibrated or jumping in the transportation and use process, and ensuring the normal use of the drying module.

[0055] With reference to Figures 3 to 11 In an embodiment, the moisture absorbing and removing assembly 100 further comprises a driving piece 130, the driving piece 130 is arranged on the mounting shell 120 and is drivingly connected with the moisture absorbing and removing piece 110; the limiting assembly comprises a first limiting piece 310, the first limiting piece 310 is arranged on the mounting shell 120 and is located on the side of the moisture absorbing and removing piece 110 close to the driving piece 130 in the axial direction, for limiting the moisture absorbing and removing piece 110 from being close to the driving piece 130 in the axial direction.

[0056] In the present embodiment, the moisture absorbing and removing piece 110 can rotate in the mounting shell 120; the driving piece 130 is a driving motor 131 or a driving motor, and the driving piece 130 is fixedly arranged on the mounting shell 120.

[0057] Specifically, the moisture absorption and removal assembly 100 is a dehumidification turntable structure, the dehumidification turntable in the dehumidification turntable structure is the moisture absorption and removal piece 110, the dehumidification turntable can be a honeycomb or corrugated turntable carrying a moisture absorbent, and the rotating dehumidification turntable can absorb and desorb the absorbed water vapor to realize repeated desorption regeneration. The dehumidification turntable includes inorganic / organic fiber carriers (such as ceramic, glass fiber, MOFs, COFs, cordierite, etc.) (MOFs is the English full name of Metal-Organic Frameworks, and the Chinese name is Metal-Organic Frameworks), and the fiber carriers are coated with molecular sieve and other moisture absorbents, which are uniformly distributed between the fiber carriers and the surface of the fiber carriers to realize the adsorption of the moisture in the air flow. The moisture absorbent can be, for example, zeolite, modified / synthetic zeolite, molecular sieve (including but not limited to A-type molecular sieve, X / Y-type molecular sieve, ZSM molecular sieve, Beta molecular sieve, and other single-crystal molecular sieves or mixed-crystal molecular sieves), high-molecular-weight moisture absorbent, alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, and other materials with moisture absorption properties.

[0058] The mounting shell 120 is divided into an adsorption zone (or a moisture absorption zone) and a regeneration zone (or a desorption zone). The shape of the mounting shell 120 can be designed according to the actual working condition requirements, as long as it includes at least two functional zones of the moisture absorption zone and the regeneration zone, and the shape of each functional zone can also be designed according to actual needs, which can be square, triangular, circular, or sector-shaped, as long as the moisture absorption zone and the regeneration zone are isolated from each other; in some embodiments, the sector-shaped can more effectively and reasonably utilize the space.

[0059] The first limiting piece 310 can be a limiting block or a shaft sleeve mounted on the inner wall surface of the mounting shell 120, which can limit the moisture absorption and removal piece 110 from approaching the driving piece 130 along the axial direction by contacting the surface of the moisture absorption and removal piece 110 close to the driving piece 130. In addition, in order to facilitate the installation of the driving piece 130 on the mounting shell 120, a first mounting groove 1211 is provided on the outer surface of the mounting shell 120, and the driving piece 130 is embedded into the first mounting groove 1211; a protective cover 140 is sleeved on the driving piece 130, and the protective cover 140 is installed on the mounting shell 120 by connecting screws.

[0060] Reference Figures 3 to 9In an embodiment, the moisture and dehumidification component 110 comprises a moisture and dehumidification body 111 and a rotating shaft 112 coaxially arranged on the moisture and dehumidification body 111 and capable of driving the moisture and dehumidification body 111 to rotate; the driving component 130 comprises a motor 131 and an output shaft 132, the output shaft 132 is sleeved with a bearing, the first limiting component 310 is the bearing, the output shaft 132 is coaxially arranged with the rotating shaft 112 and the bearing, and the rotating shaft 112 is provided with a limiting surface 1124 facing the bearing.

[0061] In the embodiment, the rotating shaft 112 can be an integral molding component with the moisture and dehumidification body 111 or can be fixedly installed on the moisture and dehumidification body 111. The groove bottom of the first mounting groove 1211 is provided with a through hole, the output shaft 132 extends through the through hole towards the rotating shaft 112 and is coaxially connected with the rotating shaft 112, so as to ensure the stable operation of the moisture and dehumidification assembly 100. The inner wall surface of the mounting shell 120 is provided with a second mounting groove 1212, the second mounting groove 1212 is communicated with the first mounting groove 1211, the bearing is embedded into the second mounting groove 1212, and the outer ring of the bearing is tightly connected with the groove wall of the second mounting groove 1212.

[0062] The bearing as the first limiting component 310 is used in cooperation with the limiting surface 1124, not only plays an axial limiting role, but also makes the cooperation between the rotating shaft 112 and the output shaft 132 more coordinated, which helps to improve the reliability of the entire moisture and dehumidification assembly 100. In addition, the above structure design is convenient for installation and maintenance, and reduces the difficulty and cost of installation and maintenance.

[0063] In a specific embodiment, the bearing adopts a ball bearing; in other embodiments, the bearing can also adopt other types of bearings, such as a sliding bearing.

[0064] In addition, the shape of the moisture and dehumidification body 111 is not limited in the application, which can be a polygon such as a triangle or a square, or a wheel disc shape. The design of the wheel disc-shaped moisture and dehumidification body 111 can make the wheel disc move circularly between the moisture absorption area and the regeneration area. The part of the wheel disc moving to the moisture absorption area adsorbs the moisture in the air, and then the part of the wheel disc adsorbing the moisture moves to the regeneration area for moisture desorption. The part of the wheel disc after desorption moves to the moisture absorption area to adsorb the moisture, which is cyclically repeated to remove the moisture in the air, thereby achieving the effect of moisture and dehumidification.

[0065] Reference Figure 6 and Figure 9In an embodiment, the rotating shaft 112 comprises a main body part 1121, a flange part 1122 and a sleeve part 1123 connected in sequence, the main body part 1121 is fixedly connected to the dehumidification body 111, the flange part 1122 has a limiting surface 1124, and the sleeve part 1123 is arranged between the output shaft 132 and the inner ring of the bearing.

[0066] In the embodiment, the main body part 1121, the flange part 1122 and the sleeve part 1123 are coaxial and integrally formed, so as to facilitate manufacturing and processing. The dehumidification body 111 is provided with a first mounting hole, the main body part 1121 is arranged in the first mounting hole and can be fixedly connected to the dehumidification body 111 by means of close fitting, screw connection or integral forming. The flange part 1122 is located on the side of the main body part 1121 close to the driving member 130 and is located outside the first mounting hole; the diameter of the flange part 1122 is greater than that of the main body part 1121 and greater than that of the sleeve part 1123; the surface of the flange part 1122 close to the sleeve part 1123 abuts against the corresponding side surface of the bearing to form the limiting surface 1124. The sleeve part 1123 is provided with a second mounting hole, the output shaft 132 is arranged and fixed in the second mounting hole, and the sleeve part 1123 is tightly fitted between the output shaft 132 and the inner ring of the bearing.

[0067] The structure of the rotating shaft 112 not only helps to improve the compatibility with other components (such as the output shaft 132 and the bearing), but also specifically speaking, different components may have certain dimensional tolerances and assembly requirements in the manufacturing process, and the multi-section structure of the rotating shaft 112 can adapt to these differences, so that different components can work cooperatively to ensure the reliability of the dehumidification assembly 100, and the installation and maintenance operations are facilitated.

[0068] Referring to Figure 6 , Figure 9 and Figure 12 In an embodiment, the limiting assembly further comprises a second limiting member 320, which is arranged on the mounting shell 120 and located on the side of the dehumidification member 110 axially away from the driving member 130, for limiting the dehumidification member 110 from moving axially away from the driving member 130.

[0069] In the embodiment, the second limiting member 320 can be a limiting block arranged on the inner wall surface of the mounting shell 120, which can limit the dehumidification member 110 from moving axially away from the driving member 130 by contacting the surface of the dehumidification member 110 away from the driving member 130. The second limiting member 320 and the first limiting member 310 are used in cooperation to limit the dehumidification member 110 from moving axially reciprocally, thereby playing a role of bidirectional limiting.

[0070] Referring to Figure 6 and Figure 9In an embodiment, the moisture absorbing and removing element 110 further comprises a connecting cover 114 coaxially connected with the rotating shaft 112 and arranged on the surface of the moisture absorbing and removing body 111 away from the driving element 130; the second limiting element 320 is a limiting protrusion coaxial with the connecting cover 114 and axially abutting against the connecting cover 114.

[0071] In the embodiment, the connecting cover 114 is located outside the first mounting hole and covers the first mounting hole; the connecting cover 114 is fixedly connected with the rotating shaft 112 through connecting screws, and at the same time, the connecting cover 114 is closely attached to the surface of the moisture absorbing and removing body 111 away from the driving element 130, so as to be installed on the moisture absorbing and removing body 111 by means of the friction force with the moisture absorbing and removing body 111. In other embodiments, the connecting cover 114 can also be installed on the moisture absorbing and removing body 111 by means of connecting screws or plug-in connection. The limiting protrusion is an integral part of the mounting shell 120, so as to facilitate manufacturing and processing; the diameter of the limiting protrusion is smaller than that of the connecting cover 114, so as to reduce the friction force applied by the limiting protrusion to the connecting cover 114.

[0072] In the application, the limiting protrusion is coaxially arranged with the rotating shaft 112, and the rotating shaft 112 is coaxially arranged with the bearing, and the limiting protrusion and the bearing used in cooperation can not only bidirectionally limit the moisture absorbing and removing element 110, so as to inhibit the axial movement of the moisture absorbing and removing element 110, but also can balance the axial force received by the moisture absorbing and removing element 110 in the axial direction, reduce the influence of the eccentric load on the moisture absorbing and removing element 110, and improve the stability of the moisture absorbing and removing element 110. In addition, in the application, the bearing applies a pressing force arranged in the axial direction to the rotating shaft 112, and at the same time, the limiting protrusion applies a pressing force arranged in the axial direction to the connecting cover 114; the above structure design is helpful to stably install the rotating shaft 112, the connecting cover 114 and the components connected therewith on the moisture absorbing and removing body 111.

[0073] Referring to Figures 3 to 9 , Figure 12 and Figure 13 In an embodiment, the limiting assembly further comprises a third limiting element 330 arranged on the mounting shell 120 and arranged along the circumferential direction of the moisture absorbing and removing element 110, for limiting the moisture absorbing and removing element 110 from moving axially close to or away from the driving element 130.

[0074] In the embodiment, the third limiting member 330 can be an annular strip and is arranged on the side of the moisture absorbing and removing member 110 axially away from the driving member 130. In other embodiments, the third limiting member 330 can also be arranged on the side of the moisture absorbing and removing member 110 axially close to the driving member 130. The third limiting member 330 arranged in this way can not only limit the axial movement of the moisture absorbing and removing member 110, but also prevent the moisture absorbing and removing member 110 from tilting based on the feature that the third limiting member 330 is arranged along the circumferential direction of the moisture absorbing and removing member 110, thereby solving the problem of the driving member 130 bearing an eccentric load due to tilting in structure.

[0075] With reference to Figures 3 to 9 And Figures 12 to 14 In an embodiment, the third limiting member 330 includes a plurality of limiting wheels axially parallel to the radial direction of the moisture absorbing and removing member 110, and the plurality of limiting wheels are arranged along the circumferential direction of the moisture absorbing and removing member 110.

[0076] In the embodiment, the inner wall surface of the mounting shell 120 is provided with a third mounting groove 1221, and the number of the third mounting groove 1221 is the same as that of the limiting wheels. The plurality of limiting wheels are arranged one by one corresponding to the plurality of third mounting grooves 1221. The limiting wheels can rotate in the corresponding third mounting grooves 1221 along the radial direction of the moisture absorbing and removing member 110 and can limit the axial movement of the moisture absorbing and removing member 110 by contacting the peripheral part of the moisture absorbing and removing member 110.

[0077] Specifically, the moisture absorbing and removing member 110 further includes a protective sleeve 113, which is sleeved on the outer circumferential surface of the moisture absorbing and removing body 111. The protective sleeve 113 includes a front sleeve 1131 and a rear sleeve 1132 connected by buckling along the axial direction of the moisture absorbing and removing body 111, and the moisture absorbing and removing body 111 is located between the front sleeve 1131 and the rear sleeve 1132. The limiting wheels can limit the axial movement of the moisture absorbing and removing member 110 by contacting the protective sleeve 113.

[0078] When the moisture absorbing and removing member 110 has a tendency to move axially, each limiting wheel can adaptively adjust the contact position and contact force according to the actual motion state of the moisture absorbing and removing member 110, so that the limiting wheel can better cope with the axial movement tendency of the moisture absorbing and removing member 110 under complex working conditions (such as uneven vibration, slight installation deviation, etc.), and prevent the moisture absorbing and removing member 110 from tilting. At the same time, the axial direction of the limiting wheel is parallel to the radial direction of the moisture absorbing and removing member 110. This structural design makes the resistance that the moisture absorbing and removing member 110 tries to move axially mainly the rolling friction of the limiting wheel, rather than the larger sliding friction, which helps to reduce the power loss of the driving member 130 and prolong the service life of the moisture absorbing and removing member 110.

[0079] In a specific embodiment, the number of limiting wheels is four, and the four limiting wheels are uniformly spaced along the circumference of the moisture and dehumidification element 110.

[0080] Referring to Figure 12 and Figure 13 In an embodiment, the limiting wheel is an integrally formed part. In this embodiment, the limiting wheel is made by overmolding; this structural design not only ensures that the limiting wheel is completely gapless and completely concentric, but also ensures that the limiting wheel has good rigidity.

[0081] Referring to Figure 1 , Figure 2 , Figure 15 and Figure 16 In an embodiment, the moisture and dehumidification element 110 has an included angle between the axial direction and the direction of gravity greater than 0°; the drying module further includes a base 400, and the drying air duct 200 is constructed on the base 400; the base 400 is provided with a first limiting groove 410 and a second limiting groove 420 spaced apart along the direction of gravity, and the mounting shell 120 is inserted into the first limiting groove 410 and the second limiting groove 420, and the first limiting groove 410 and the second limiting groove 420 are used to limit the movement of the mounting shell 120 along the direction of gravity.

[0082] In this embodiment, the included angle between the axial direction of the moisture and dehumidification element 110 and the direction of gravity is 90°, and in other embodiments, the included angle between the axial direction of the moisture and dehumidification element 110 and the direction of gravity can also be an acute angle. The first limiting groove 410 is located below the second limiting groove 420, a part of the structure of the mounting shell 120 is inserted into the first limiting groove 410, another part of the structure is inserted into the second limiting groove 420, and the remaining structure is located in the region between the first limiting groove 410 and the second limiting groove 420.

[0083] In this application, the first limiting groove 410 and the second limiting groove 420 spaced apart function as a limiting effect on the mounting shell 120; when the drying module as a whole vibrates, the first limiting groove 410 and the second limiting groove 420 can effectively limit the mounting shell 120 and the moisture and dehumidification element 110 in the mounting shell 120 from moving up and down along the direction of gravity; the above-mentioned limiting method provides basic rigid limiting for the moisture and dehumidification assembly 100 in the direction of gravity, greatly reducing the up and down vibration caused by vibration.

[0084] The first limiting groove 410 and the second limiting groove 420 limit the installation shell 120 from the direction of gravity, and the limiting assembly limits the moisture and dehumidification piece 110 from the axial direction, which limits the moisture and dehumidification assembly 100 from different directions, thereby forming a stable constraint system, so that the moisture and dehumidification assembly 100 can be stably positioned in the position where it should be during transportation and use, even if it is affected by the vibration of the drying module as a whole, and the phenomenon of up and down vibration or jumping is avoided, thereby ensuring the normal use of the drying module.

[0085] With reference to Figure 1 , Figure 2 and Figures 15 to 17 , in an embodiment, the base 400 is provided with two limiting columns 430 arranged at intervals, and the installation shell 120 is limited between the two limiting columns 430. In the embodiment, the front shell 121 and the rear shell 122 are in contact with the opposite surfaces of the two limiting columns 430, respectively.

[0086] With reference to Figures 3 to 9 and Figure 18 , in an embodiment, the limiting assembly further comprises a fourth limiting piece 340 arranged on the installation shell 120, and the fourth limiting piece 340 is below the axis of the moisture and dehumidification piece 110 in the direction of gravity, and is used to support the moisture and dehumidification piece 110.

[0087] In the embodiment, the fourth limiting piece 340 can be a support block or a support column. The fourth limiting piece 340 is arranged to play a supporting role, so as to avoid the moisture and dehumidification piece 110 from sagging due to its own weight, and to stabilize the position of the moisture and dehumidification piece 110 in the drying air duct 200.

[0088] With reference to Figures 3 to 9 and Figure 18 , in an embodiment, the fourth limiting piece 340 is a support wheel, the axis of the support wheel is parallel to the rotating shaft 112, and the support wheel is in rolling cooperation with the peripheral part of the moisture and dehumidification piece 110.

[0089] In the embodiment, the support wheel is in rolling cooperation with the protective sleeve 113 on the moisture and dehumidification piece 110. The above structure design can make the resistance mainly the rolling friction of the support wheel when the moisture and dehumidification piece 110 attempts to sag, instead of the larger sliding friction, under the premise of ensuring the supporting effect, which is helpful to reduce the power loss of the driving piece 130 and prolong the service life of the moisture and dehumidification piece 110.

[0090] With reference to Figures 3 to 9 and Figure 18 , in an embodiment, the plane passing through the axis of the rotating shaft 112 and parallel to the direction of gravity is the middle cross section of the moisture and dehumidification piece 110, the number of the support wheels is multiple, and the support wheels are evenly distributed on both sides of the middle cross section.

[0091] In the embodiment, the number of support wheels is two, and in other embodiments, the number of support wheels can also be four, six or more. The plurality of support wheels are evenly distributed on both sides of the cross section of the moisture sorption and desorption element 110, which can ensure that the moisture sorption and desorption element 110 is uniformly supported in the direction of gravity; such uniform support can keep the center of gravity of the moisture sorption and desorption element 110 stable, avoiding tilting or shaking due to uneven support. At the same time, the evenly distributed support wheels also help to ensure the stability of the rotation of the moisture sorption and desorption element 110, and structurally decompose the deformation and shear force caused by the sinking of the moisture sorption and desorption element 110 due to gravity.

[0092] With reference to Figure 18 In an embodiment, the support wheel is a one-piece component. In the embodiment, the support wheel is made by overmolding; this structural design not only ensures that the support wheel is completely gapless and completely concentric, but also ensures that the support wheel has good rigidity.

[0093] With reference to Figures 3 to 9 , Figure 14 and Figure 17 In an embodiment, the mounting shell 120 includes a front shell 121 and a rear shell 122 that are connected by buckling connection in the axial direction of the moisture sorption and desorption assembly 100, the first limiting member 310 is arranged on the front shell 121, the second limiting member 320 and the third limiting member 330 are arranged on the rear shell 122, and the fourth limiting member 340 is arranged between the front shell 121 and the rear shell 122.

[0094] In the embodiment, the first mounting groove 1211 is arranged on the outer surface of the front shell 121, and the second mounting groove 1212 is arranged on the inner wall surface of the front shell 121; the second limiting member 320 is arranged on the inner wall surface of the rear shell 122, and the third mounting groove 1221 is arranged on the inner wall surface of the rear shell 122; the fourth mounting groove is arranged on the inner wall surface of the rear shell 122 close to the front shell 121, the fifth mounting groove is arranged on the inner wall surface of the front shell 121 close to the rear shell 122, and the two ends of the support wheel are respectively arranged in the fourth mounting groove and the fifth mounting groove.

[0096] In the embodiment of the present application, the clothes treatment apparatus is a clothes dryer. In the present application, the limiting assembly provides a stable blocking force in the axial direction of the moisture absorbing and removing element 110, so that the moisture absorbing and removing element 110 can be limited from displacement in the axial direction when subjected to external vibration (whether it is the bumping vibration in the transportation process or the vibration generated by the operation of the drying module itself in the use process), thereby reducing the possibility of the moisture absorbing and removing element 110 from shaking or jumping in the transportation and use process, and ensuring the normal use of the drying module.

[0097] In summary, the drying module and clothes treatment apparatus provided by the embodiment have at least the following beneficial technical effects: In the present application, the limiting assembly provides a stable blocking force in the axial direction of the moisture absorbing and removing element 110, so that the moisture absorbing and removing element 110 can be limited from displacement in the axial direction when subjected to external vibration (whether it is the bumping vibration in the transportation process or the vibration generated by the operation of the drying module itself in the use process), thereby reducing the possibility of the moisture absorbing and removing element 110 from shaking or jumping in the transportation and use process, and ensuring the normal use of the drying module.
