[0055] Please refer to Figure 1 and Figure 2 The laundry treatment apparatus comprises a housing 1, which comprises the first support 11 described above. As shown in Figure 1 The housing 1 is a polyhedron or a three-dimensional hollow structure similar to a polyhedron. As shown in Figure 2 and Figure 3 The drum 2 is rotatably arranged inside the housing 1. At least one face of the housing 1 is provided with an openable and closable door panel (not shown), and the axial first end 22 of the drum 2 corresponds to the door panel, and the door panel is used to open or close the laundry treatment space 20 of the drum 2. Please refer to Figure 3 and Figure 4 The opening on the axial first end 22 is defined as the first opening 21. The other end of the drum 2 is an axial second end 24.

[0056] The support portion 111 has a certain axial height.

[0057] In one embodiment, please refer to Figure 6 and Figure 9 The axial first end 22 of the drum 2 is sleeved on the support portion 111 and arranged at a certain distance in the radial direction from the support portion 111.

[0058] The first seal 3 is in the form of a closed ring.

[0059] In an optional embodiment, the support portion 111 is annular. Further optionally, the support portion 111 can be a closed annular.

[0060] As shown in Figure 1 and Figure 2 , in addition to the first support member 11, the housing 1 can further include a second support member 12, which is arranged at the axial second end 24 of the drum 2, for supporting the rotating drum 2. At least the first support member 11 and the second support member 12 jointly constitute a rotating support assembly of the drum 2. In addition, the housing 1 further includes a plurality of side plates 14 and a base 13, which are connected with each other to define a space inside the housing 1. Based on the use scenario of the laundry treatment apparatus 100, the first support member 11 is located in front of the drum 2 (the side of the laundry treatment apparatus 100 facing the user is the front), the second support member 12 is located behind the drum 2, the base 13 is located below the drum 2, and the plurality of side plates 14 can be respectively located at the left side, the right side, the upper side, etc. of the drum 2. Of course, the housing 1 is not limited to a hexahedron, and according to specific needs, the housing 1 can be provided in other shapes, and the plurality of side plates 14 can be arranged in other orientations.

[0061] As shown in Figure 6 , the outer circumferential surface of the support portion 111 serves as a support surface 1110. In an embodiment, the inner circumferential surface of the first seal member 3 is sealingly connected with the support surface 1110, and the outer circumferential surface of the first seal member 3 is sealingly connected with the inner circumferential surface of the axial first end 22 of the drum 2. Since the drum 2 is arranged to rotate relative to the first support member 11, the first seal member 3 is configured such that the inner circumferential surface of the first seal member 3 is rotatably sealingly connected with the support surface 1110, or the outer circumferential surface of the first seal member 3 is rotatably sealingly connected with the inner circumferential surface of the axial first end 22 of the drum 2. That is, the first seal member 3 is configured to be fixed on the drum 2 and rotate with the drum 2, or be fixed on the support portion 111.

[0062] As shown in Figure 6 , Figure 10 and Figure 11 , in an embodiment, the first seal member 3 includes a first sealing layer 32, which is a layer structure capable of being elastically deformed in the radial direction, and the first sealing layer 32 is compressed between the support surface 1110 and the inner circumferential surface of the axial first end 22 of the drum 2. The purpose of such an arrangement is that the first sealing layer 32 can maintain a state of being radially compressed, thereby being able to provide effective sealing.

[0063] In an embodiment, as shown in Figure 6 , Figure 10 and Figure 11As shown, the first seal 3 further comprises a first connecting layer 31. The first connecting layer 31 is configured to connect the first seal layer 32 with the inner circumferential surface of the axial first end 22 of the roller 2, or to connect the first seal layer 32 with the support surface 1110.

[0064] As shown, in one embodiment, the first seal layer 32 is connected with the outer circumferential surface of the first connecting layer 31, and the first seal layer 32 is located radially outside the first connecting layer 31. In this case, the inner circumferential surface of the first connecting layer 31 is configured to be fixedly connected with the support surface 1110, and the outer circumferential surface of the first seal layer 32 is configured to be rotatably sealed with the inner circumferential surface of the axial first end 22 of the roller 2. Figure 10 As shown, in one embodiment, the first seal layer 32 is connected with the inner circumferential surface of the first connecting layer 31, and the first seal layer 32 is located radially inside the first connecting layer 31. In this case, the outer circumferential surface of the first connecting layer 31 is configured to be fixedly connected with the inner circumferential surface of the axial first end 22 of the roller 2, and the inner circumferential surface of the first seal layer 32 is configured to be rotatably sealed with the support surface 1110.

[0065] Figure 11 As shown, in one embodiment, the first seal layer 32 is connected with the inner circumferential surface of the first connecting layer 31, and the first seal layer 32 is located radially inside the first connecting layer 31. In this case, the outer circumferential surface of the first connecting layer 31 is configured to be fixedly connected with the inner circumferential surface of the axial first end 22 of the roller 2, and the inner circumferential surface of the first seal layer 32 is configured to be rotatably sealed with the support surface 1110.

[0066] In one embodiment, the first connecting layer 31 comprises an adhesive layer. The first connecting layer 31 is adhered to the support surface 1110 or the inner circumferential surface of the axial first end 22 of the roller 2 to achieve fixed connection therebetween.

[0067] In one embodiment, the side surface of the first connecting layer 31 away from the first seal layer 32 is provided with an adhesive layer. The first connecting layer 31 itself can be a structure layer without adhesive property, and it achieves fixed connection with the support surface 1110 or the inner circumferential surface of the axial first end 22 of the roller 2 through the additional adhesive layer.

[0068] In one embodiment, the first connecting layer 31 comprises an elastic member capable of being elastically deformed in the radial direction. In this case, the first connecting layer 31 is kept on the support surface 1110 or the inner circumferential surface of the axial first end 22 of the roller 2 by its elastic deformation in the radial direction. For example, the first connecting layer 31 is a rubber ring which, after being stretched in the radial direction, has the characteristic of automatically retracting inward in the radial direction. In this case, the first connecting layer 31 is adapted to be sleeved on the support surface 1110 and kept fixed relative to the support part 111 by the radial pressure between the first connecting layer 31 and the support surface 1110. For another example, the first connecting layer 31 is a hard ring member with a notch, and the hard ring member with a notch can be compressed in the radial direction. In this case, the first connecting layer 31 is adapted to be pressed against the inner circumferential surface of the axial first end 22 of the roller 2 and kept fixed relative to the axial first end 22 of the roller 2 by the radial pressure between the first connecting layer 31 and the inner circumferential surface of the axial first end 22 of the roller 2.

[0069] ​In one embodiment, the first connecting layer 31 comprises a circumferentially closed hard ring which is in interference fit with the inner circumferential surface of the support surface 1110 or the axial first end 22 of the roller 2. For example, the first connecting layer 31 comprises a metal ring, the inner diameter of which is set to be smaller than the outer diameter of the support portion 111, or the outer diameter of which is set to be larger than the inner diameter of the axial first end 22 of the roller 2.

[0070] In other embodiments, the first sealing member 3 can be fixedly connected or relatively fixed to the roller 2 or the support portion 111 in other ways. For example, the first sealing member 3 is arranged between the support surface 1110 and the inner circumferential surface of the axial first end 22 without additional fixing structure, and during rotation of the roller 2, the first sealing member 3 is kept relatively fixed to the roller 2 by friction between the first sealing member 3 and the roller 2, or kept relatively fixed to the first support member 11 by friction between the first sealing member 3 and the support surface 1110.

[0071] In one embodiment, the first sealing layer 32 comprises a bristle layer. The bristle layer comprises a plurality of bristles arranged side by side. The length direction of the bristles is radial. Since the diameter of each bristle is small, the bristles have a certain flexibility, and the bristle layer formed by a plurality of bristles can be deformed in the length direction.

[0072] At the same time, by setting a sufficient density of the bristles, the sealing effect between the roller 2 and the support portion 111 can be ensured.

[0073] In one embodiment, the first sealing layer 32 comprises a bristle layer. The bristle layer comprises a plurality of bristles arranged side by side. The length direction of the bristles is radial. Since the diameter of each bristle is small, the bristles have a certain flexibility, and the bristle layer formed by a plurality of bristles can be deformed in the length direction.

[0074] It can be understood that when the first sealing layer 32 comprises a bristle layer, the bristle layer is adapted to be arranged on the first connecting layer 31.

[0075] In one embodiment, the first sealing layer 32 comprises a layer of elastic porous material, for example, a sponge layer, more specifically, a polyurethane sponge layer. The layer of elastic porous material has the ability of elastic deformation due to its porous structure. The layer of elastic porous material can or can not be arranged on the first connecting layer 31.

[0076] In one embodiment, the first sealing layer 32 comprises at least one of an elastic silica gel layer, an elastic rubber layer and an elastic plastic layer. For example, the first sealing layer 32 can comprise an elastic silica gel layer and an elastic rubber layer, or an elastic rubber layer and an elastic plastic layer. At this time, the first sealing layer 32 can or can not be arranged on the first connecting layer 31.

[0077] In some embodiments, the first sealing layer 32 can adopt a combination of the above-mentioned multiple types. For example, the first sealing layer 32 can include an elastic silica gel layer and a sponge layer, and for another example, the first sealing layer 32 can include a bristle layer and a sponge layer, and so on. More combination forms will not be listed one by one.

[0078] In an optional embodiment, the height of the first sealing member 3 in the radial direction is set to have an interference with the roller 2 of greater than or equal to 2 mm. Further optionally, the height of the first sealing member 3 in the radial direction is set to have an interference with the roller 2 of greater than or equal to 2.5 mm. Further optionally, the height of the first sealing member 3 in the radial direction is set to have an interference with the roller 2 of greater than or equal to 3 mm.

[0079] The purpose of such a setting is that the first sealing member 3 has a large deformation amount, which can ensure the sealing cooperation between the roller 2 and the support part 111, and at the same time, can also ensure the sealing cooperation between the roller 2 and the support part 111 when the roller 2 jumps in the radial direction.

[0080] In an optional embodiment, the height of the first sealing member 3 in the axial direction is greater than or equal to 5 mm. On the one hand, this makes the blocking effect of the inner and outer spaces of the roller 2 more obvious, and on the other hand, it can further adapt to the axial position deviation of the roller 2, that is, even if the roller 2 jumps greatly in the axial direction or an axial assembly deviation is generated between the roller 2 and the first support member 11 during the assembly process, the first sealing member 3 can still reliably provide a sealing effect.

[0081] In an embodiment, as shown in Figure 7 , Figure 8 and Figure 9 , the laundry treating apparatus 100 further includes a second sealing member 4, which is arranged between the end surface of the axial first end 22 of the roller 2 and the axial side surface of the first support member 11, and which forms a dynamic seal between the roller 2 and the first support member 11.

[0082] The second sealing member 4 is used to further block the inner and outer spaces of the axial first end 22 of the roller 2, and forms a double seal with the first sealing member 3, which is conducive to further improving the sealing performance of the laundry treating space 20 of the roller 2.

[0083] Specifically, as shown in Figure 9 , the axial side surface of the side of the first support member 11 facing the roller 2 includes a limiting surface 112 extending radially outward from the outer circumferential surface of the support part 111. The second sealing member 4 is arranged between the relatively rotating roller 2 and the support part 111, and therefore, the second sealing member 4 is configured to be fixed on the limiting surface 112 and keep a rotary seal with the axial first end 22 of the roller 2, or to be fixed on the end surface of the axial first end 22 of the roller 2 and keep a rotary seal with the limiting surface 112.

[0084] Since the axial position of the axial first end 22 of the roller 2 is limited by the limiting surface 112, or in other words, the part surface of the first support 11 on the side facing the roller 2 opposite to the axial first end 22 of the roller 2 is the limiting surface 112, therefore, the radial height of the limiting surface 112 is generally greater than the radial thickness of the axial first end 22 of the roller 2, thus, it is also beneficial to maintain good sealing between the axial first end 22 and the limiting surface 112 when the roller 2 occurs radial excursion. In addition, in some cases, the roller 2 is made of sheet metal, and the radial thickness of the axial first end 22 or the overall radial thickness of the roller 2 is generally within a small range, such as not more than 5 millimeters.

[0085] Based on this, in an alternative embodiment, the second sealing member 4 is configured to be fixed on the limiting surface 112 and maintain rotational sealing with the axial first end 22 of the roller 2.

[0086] In addition, please continue to refer to Figure 9 It is shown that for the roller 2 of sheet metal, the axial first end 22 is generally provided with an outwardly bent flange structure 23 to enhance the strength of the axial first end 22 and prevent the axial first end 22 from being deformed radially, at the same time, the flange structure 23 also avoids the sharp edge of the axial first end 22, which is beneficial to assembly operation. The surface of the flange structure 23 facing the first support 11 is curved.

[0087] Based on this, in an alternative embodiment, the second sealing member 4 is configured to be fixed on the limiting surface 112 and maintain rotational sealing with the axial first end 22 of the roller 2.

[0088] For the roller 2 with the flange structure 23, the flange structure 23 and the second sealing member 4 are in line contact, therefore, the friction between the roller 2 and the second sealing member 4 is small.

[0089] In an embodiment, please refer to Figure 10 , Figure 11 and Figure 13 It is shown that the second sealing member 4 includes a second sealing layer 42. The second sealing layer 42 is a layer structure capable of being elastically deformed in the axial direction, and the second sealing layer 42 is compressed between the limiting surface 112 and the end surface of the axial first end 22 of the roller 2. The purpose of such arrangement is that the second sealing layer 42 can maintain the state of being axially compressed, thereby being able to provide more effective sealing effect.

[0090] Please continue to refer to Figure 13As shown, in one embodiment, the second sealing member 4 further comprises a second connecting layer 41, which is axially stacked and connected with the second sealing layer 42. The second connecting layer 41 is configured to connect the second sealing layer 42 with the limiting surface 112, and the second sealing layer 42 is configured to keep a rotational seal with the end surface of the axial first end 22 of the roller 2, or the second connecting layer 41 connects the second sealing layer 42 with the end surface of the axial first end 22.

[0091] In one embodiment, the second connecting layer 41 comprises an adhesive layer. The second connecting layer 41 is adhered with the limiting surface 112, or adhered with the end surface of the axial first end 22.

[0092] In one embodiment, the second connecting layer 41 is provided with an adhesive layer on the side surface away from the second sealing layer 42. The second connecting layer 41 itself can be a structure layer without adhesive property, and the fixed connection between the second connecting layer 41 and the limiting surface 112 or the end surface of the axial first end 22 is achieved through the additional adhesive layer.

[0093] In one embodiment, the second connecting layer 41 comprises an elastic member capable of being elastically deformed in the radial direction. At this time, the second connecting layer 41 is kept on the supporting surface 1110 and then kept on the limiting surface 112 by means of the elastic deformation in the radial direction. For example, the second connecting layer 41 is a rubber ring, which has the characteristic of automatically retracting in the radial direction after being stretched in the radial direction. At this time, the second connecting layer 41 is adapted to be sleeved on the supporting surface 1110 and abut against the limiting surface 112, and is kept in relative fixation with the supporting part 111 and the limiting surface 112 by means of the radial pressure between the second connecting layer 41 and the supporting surface 1110.

[0094] In one embodiment, the second connecting layer 41 comprises a circumferentially closed hard ring member, which is in interference fit with the supporting part 111. For example, the second connecting layer 41 comprises a metal ring, and the inner diameter of the metal ring is set to be smaller than the outer diameter of the supporting part 111. Thus, the second connecting layer 41 is fixed on the supporting part 111 and can abut against and be fixed on the limiting surface 112.

[0095] In other embodiments, the second sealing member 4 can be fixedly connected or kept in relative fixation with the limiting surface 112 in more ways. For example, the second sealing member 4 is placed between the limiting surface 112 and the end surface of the axial first end 22, and no additional fixing structure is needed. During the rotation of the roller 2, the friction between the roller 2 and the second sealing member 4 is smaller than the friction between the second sealing member 4 and the limiting surface 112, and the second sealing member 4 will not be driven to rotate.

[0096] In one embodiment, the second sealing layer 42 comprises a bristle layer. The bristle layer comprises a plurality of bristles arranged side by side. The length direction of the bristles is the axial direction. Since the diameter of the bristles is small, the bristles have a certain flexibility, and the bristle layer composed of a plurality of bristles can be deformed in the length direction.

[0097] It can be understood that when the second sealing layer 42 comprises a bristle layer, the bristle layer is adapted to be arranged on the second connecting layer 41.

[0098] In one embodiment, the second sealing layer 42 comprises a layer of elastic porous material, for example, comprises a sponge layer, more specifically, a polyurethane sponge layer. The layer of elastic porous material has the ability of elastic deformation due to its porous structure. The layer of elastic porous material can be arranged on the second connecting layer 41 or can not necessarily be arranged on the second connecting layer 41.

[0099] In one embodiment, the second sealing layer 42 comprises at least one of an elastic silicone layer, an elastic rubber layer or an elastic plastic layer. For example, the second sealing layer 42 can comprise an elastic silicone layer and an elastic rubber layer, or, comprises an elastic rubber layer and an elastic plastic layer. At this time, the second sealing layer 42 can be arranged on the second connecting layer 41 or can not necessarily be arranged on the second connecting layer 41.

[0100] In some embodiments, the second sealing layer 42 can adopt combinations of the above-mentioned various forms. For example, the second sealing layer 42 can comprise an elastic silicone layer and a sponge layer, and the like. More combination forms will not be listed one by one.

The purpose of such arrangement is to connect the first sealing member 3 and the second sealing member 4 to form a sealing structure in the shape of "L", which is adapted to the "L"-shaped surface formed by the support surface 1110 and the limiting surface 112, so as to fill the passage between the support surface 1110 and the axial first end 22 of the drum 2 as much as possible, thereby improving the sealing effect.

[0107] Alternatively, the axial first end 22 of the drum 2 is not provided with the above-mentioned folded edge structure 23, so as to avoid interference with the first sealing member 3.

[0108] Correspondingly, the first connecting layer 31 of the first sealing member 3 can be bonded to the outer circumferential surface of the axial first end 22 of the drum 2 or the support surface 1110 of the support portion 111; the first connecting layer 31 can be bonded to the outer circumferential surface of the axial first end 22 of the drum 2 or the support surface 1110 of the support portion 111 through an additionally provided bonding layer; the first connecting layer 31 can be elastically sleeved on the outer circumferential surface of the axial first end 22 of the drum 2 or elastically pressed against the support surface 1110 of the support portion 111; or the first connecting layer 31 can be in interference fit with the outer circumferential surface of the axial first end 22 of the drum 2 or the support surface 1110 of the support portion 111.

[0112] Figure 2 In one embodiment, the laundry treating apparatus 100 is a clothes dryer. Thus, as shown in FIG. 1,​Figure 2 As shown, the laundry treating apparatus 100 further comprises a drying module 5, which is arranged in the housing 1 and outside the drum 2, and is configured to provide circulating air into the laundry treating space 20 of the drum 2 to remove moisture from the laundry.

[0113] Please refer to Figure 2 As shown, a drying air duct 10 is arranged in the housing 1 and outside the drum 2, and is in communication with the air inlet and the air outlet of the drum 2. The drying module 5 is arranged in the drying air duct 10.

[0114] At least a part of the first opening 21 of the axial first end 22 of the drum 2 serves as the air outlet of the drum 2. The air inlet of the drum 2 can be arranged at the axial second end 24 of the drum 2, or can be arranged at other positions of the drum 2. Specifically, please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in one embodiment, the first support 11 is provided with a ventilation hole 114, which is in communication with the first opening 21 of the axial first end 22 of the drum 2 and the drying air duct 10. The circulating air from the laundry treating space 20 enters the drying air duct 10 in sequence through the first opening 21 and the ventilation hole 114, and is dehumidified by the drying module 5. The dehumidified circulating air enters the laundry treating space 20 again through the air inlet of the drum 2. Such circulation realizes continuous dehumidification of the laundry.

[0115] Optionally, the drying module 5 comprises an evaporator. The evaporator is configured to cool the air in the drying air duct 10, so that part of the water vapor in the air is removed in a condensed manner.

[0116] Optionally, the drying module 5 comprises a moisture absorption zone of a dehumidification wheel. The dehumidification wheel comprises a porous moisture absorption medium. The humid air passes through the dehumidification wheel, and the porous moisture absorption medium in the dehumidification wheel absorbs the water vapor in the air, thereby reducing the humidity of the air. Another part of the dehumidification wheel is a regeneration zone, and high-temperature air passes through the regeneration zone, so that the water absorbed by the moisture absorption medium is desorbed, thereby restoring the moisture absorption capacity of the moisture absorption medium. The part with restored moisture absorption capacity is rotated to the drying air duct 10 again, and such rotation is repeated to realize dehumidification.

[0117] In one embodiment, the drying module 5 comprises an evaporator and a moisture absorption zone of a dehumidification wheel connected in sequence, realizing double dehumidification function and improving dehumidification efficiency. In addition, during the moisture absorption process of the dehumidification wheel, the water molecules are adsorbed onto the porous moisture absorption medium, and the degrees of freedom of the water molecules are reduced, and the kinetic energy is converted into heat energy and released. In this way, the temperature of the circulating air can be increased after passing through the moisture absorption zone of the dehumidification wheel. The heated air enters the drum 2 again and removes the water molecules from the laundry, which is beneficial to improve the dehumidification efficiency.

[0118] Please refer toFigure 3 、 Figure 4 and Figure 5 As shown in FIGS. 1, 2 and 3, the first support 11 is provided with a second opening 110, which is in axial communication with the first opening 21, and a ventilation hole 114 is arranged on the inner circumferential surface of the second opening 110. This is conducive to the positional arrangement between the first opening 21 and the drying air duct 10.

[0119] In addition, the laundry treating apparatus 100 further comprises a drive assembly 6, which is arranged in the housing 1 and outside the drying air duct 10, and is connected with the drum 2 for driving the drum 2 to rotate. The drive assembly 6 is not limited in form, and may, for example, comprise a motor and a synchronous belt, or may comprise a motor and a gear, etc.

[0120] In one embodiment, the laundry treating apparatus 100 is a washing machine. Therefore, the laundry treating apparatus 100 further comprises a pipeline assembly (not shown), which is in communication with an external water source and the drum 2, and is used to supply water required for washing laundry into the drum 2.

[0121] In one embodiment, the laundry treating apparatus 100 is a washing machine with a drying function. Therefore, the laundry apparatus can simultaneously comprise the drying module 5 and the pipeline assembly described above.
