For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0032] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0033] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, the technical term "contact" should be understood in a broad sense, and may be direct contact or contact through an intermediate medium layer. It may be contact with essentially no interaction force between the two contacting parties, or it may be contact with interaction force between the two contacting parties.

[0034] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] See also Figures 1 to 3 In a first aspect, an embodiment of the present application provides a clothing processing device, comprising a housing 20 and a clothing processing drum 10 according to any embodiment of the present application.

[0036] It should be noted that the clothing processing device 100 may be a clothes dryer with a drying function, or a washer-dryer, etc., and is not limited here.

[0037] The laundry treatment drum 10 is disposed in a housing 20, which can be understood as an external frame structure of the laundry treatment device 100, and its specific shape is not limited. Figure 1 As shown, the box body 20 is roughly a cubic structure; of course, the box body 20 can also be an elliptical structure, etc.

[0038] The laundry treatment drum 10 has a laundry treatment chamber 10a. The laundry is dried in the laundry treatment chamber 10a. Figure 1 As shown, one side of the laundry processing chamber 10a is opened to form a laundry loading port, through which a user can conveniently take in and put in laundry.

[0039] Exemplarily, the laundry processing apparatus 100 further includes a driving assembly for driving the laundry processing drum 10 to rotate around a central axis of the laundry processing drum 10 .

[0040] For example, see Figure 3 The driving assembly includes a motor, a belt and a roller assembly 40. The roller assembly 40 is used to support the clothing treatment drum 10. The motor drives the clothing treatment drum 10 to rotate through the belt transmission.

[0041] For example, see Figure 2 and Figure 3 The laundry processing apparatus 100 further includes a front support 30 , which is connected to the housing 20 and is used to support the front portion of the laundry processing tub 10 .

[0042] Exemplarily, the laundry treating apparatus 100 further includes a condensing device and a drying device.

[0043] Condensate is introduced into the condensing device, and the wet airflow in the laundry processing chamber 10a can flow into the condensing device, and under the action of the condensate, the water vapor in the wet airflow releases heat and condenses. That is, after passing through the condensing device, the wet airflow can become a dry airflow.

[0044] A heating element is provided in the drying device, and the heating element may be, for example, a heating tube, which is electrically connected to the power supply assembly, so that electrical energy can be converted into thermal energy. The dry airflow formed after condensation by the condensing device passes through the drying device and is heated by the heating element to obtain a dry hot airflow. The dry hot airflow enters the clothing processing chamber 10a, exchanges heat and moisture with the wet clothing, absorbs moisture from the clothing, and the dry hot airflow gradually turns into a wet airflow. Under the action of the dry hot airflow, the clothing gradually achieves a drying effect.

[0045] In order to facilitate the circulation of airflow in the clothing processing chamber 10a, the condensing device and the drying device, in some embodiments, the clothing processing device 100 also includes a fan assembly, which is arranged on the circulation flow path of the airflow, for example, can be arranged in the drying device, so as to guide the circulation of the airflow.

[0046] The type of the fan assembly is not limited, and can be, for example, a centrifugal fan, an axial flow fan, etc.

[0047] In addition to the heating element and the fan assembly, the electronic devices installed in the drying device may also include other types, such as temperature sensors, etc. The temperature of the airflow in the drying device can be monitored in real time by the temperature sensor, thereby controlling the heat emitted by the heating element.

[0048] For example, see Figure 2 and Figure 3The clothing processing device 100 further includes a sealing ring 50 , which is disposed between the front support 30 and the clothing processing tub 10 .

[0049] The sealing ring 50 can be in close contact with the clothes processing drum 10 , thereby ensuring the sealing effect of the sealing ring 50 and ensuring the drying efficiency of the clothes processing device 100 .

[0050] It should be noted that the specific type of the sealing ring 50 is not limited herein. By way of example, the sealing ring 50 is, for example, felt.

[0051] See also Figures 1 to 3 In the second aspect, the embodiment of the present application provides a clothing treatment drum 10, which is an integrated structure. The clothing treatment drum 10 includes a barrel 10b and a contraction section 10c. The contraction section 10c is located at at least one end of the barrel 10b in the axial direction, and contracts inwardly along the radial direction of the clothing treatment drum 10. Among them, the contraction section 10c includes a first connecting section 10d and a second connecting section 10e, the first connecting section 10d is located at one end of the second connecting section 10e away from the barrel 10b, and the outer diameter of the first connecting section 10d is smaller than the outer diameter of the second connecting section 10e.

[0052] The laundry treatment tub 10 comprises a tub body 10b and a contraction section 10c, and the tub body 10b and the contraction section 10c together define a laundry treatment chamber 10a.

[0053] The contraction section 10c is located at at least one end of the barrel 10b along the axial direction, that is, the contraction section 10c may be provided at one end of the barrel 10b along the axial direction, or may be provided at both ends of the barrel 10b along the axial direction.

[0054] In the embodiment of the present application, both ends of the barrel 10b along the axial direction are provided with contraction sections 10c. In other words, the front end of the barrel 10b and the rear end of the barrel 10b are both provided with contraction sections 10c.

[0055] The contraction section 10c contracts inwardly along the radial direction of the laundry treatment tub 10, that is, the outer diameter of the contraction section 10c is smaller than the outer diameter of the tub body 10b.

[0056] Here, by forming a contraction section 10c at the end of the tub body 10b, the problem of a large closing of the laundry treatment tub 10 is overcome.

[0057] The clothes processing drum 10 is an integrated structure, that is, the drum body 10b and the contraction section 10c are integrally formed, rather than assembling the drum body 10b and the contraction section 10c together, which is beneficial to reduce parts, improve manufacturing efficiency and reduce manufacturing costs.

[0058] Here, please see Figure 2 and Figure 3The contraction section 10c includes a first connecting section 10d and a second connecting section 10e, and the first connecting section 10d is located at an end of the second connecting section 10e away from the barrel 10b.

[0059] Thus, the first connecting section 10d can be used to cooperate with the front support 30 to achieve support for the front of the laundry treatment drum 10, for example, by pasting a sealing ring 50 on the first connecting section 10d to achieve a sealed fit between the front support 30 and the sealing ring 50.

[0060] The roller assembly 40 is supported on the second connecting section 10e, and the motor drives the clothes processing drum 10 to rotate through a belt transmission.

[0061] Here, the outer diameter of the first connecting section 10d is smaller than the outer diameter of the second connecting section 10e, so as to achieve the function of supporting and sticking the felt of the separation roller assembly 40. In other words, the contraction section 10c contracts in a step-like manner instead of contracting all the way to the first connecting section 10d. This helps to reduce the difficulty of forming the clothing processing drum 10. In addition, it also helps to increase the volume of the clothing processing chamber 10a.

[0062] The specific manner in which the laundry processing drum 10 is integrally formed is not limited herein.

[0063] For related technologies, see Figure 4 and Figure 5 The cylindrical clothing treatment drum 10' is made of, for example, a metal steel plate made of a material such as stainless steel. Specifically, the metal steel plate made of a material such as stainless steel is first rolled into a cylindrical shape and then the connecting parts where the steel plates are in contact are welded to form the cylindrical clothing treatment drum 10'. Then, with the two ends of the clothing treatment drum 10' in a clamped state, a plurality of molds located on the inner side of the drum are used to push the corresponding parts of the inner circumference of the drum from the inside to the outside to expand in the central part to form a barrel 10b', that is, the outer diameter of the barrel 10b' is larger than the outer diameter of the contraction section 10c'. In this way, a clothing treatment drum 10' with the contraction section 10c' as one section is formed.

[0064] It should be noted that this structure has high requirements on materials and molding equipment. The barrel mouth of the clothing treatment drum 10' needs to expand more than 20mm on one side, which is more likely to cause problems such as material wrinkles and weld cracks, which will lead to high resistance during the rotation of the clothing treatment drum 10' and produce problems such as abnormal noise.

[0065] In the embodiment of the present application, a metal steel plate made of a material such as stainless steel is first rolled into a cylindrical shape and then the connecting parts of the steel plates are welded to form a cylindrical clothes treatment drum 10. Then, when the two ends of the clothes treatment drum 10 are in a clamped state (the clamped area of ​​the clothes treatment drum 10 is the first connecting section 10d), a plurality of molds located inside the drum are used to push the corresponding parts of the inner circumference of the drum from the inside to the outside to expand the central part to form a second connecting section 10e, that is, the outer diameter of the second connecting section 10e is larger than the first connecting section 10d. the outer diameter of the connecting section 10d; then, with the two ends of the second connecting section 10e in a clamped state (the clamped area of ​​the clothing treatment drum 10 is the second connecting section 10e), the corresponding parts of the inner circumference of the drum are pushed out from the inside to the outside by the plurality of molds located on the inner side of the drum to expand in the central part to form the drum body 10b, that is, the outer diameter of the drum body 10b is larger than the outer diameter of the second connecting section 10e, thus, the contraction section 10c of the clothing treatment drum 10 including the first connecting section 10d and the second connecting section 10e is formed.

[0066] It should be noted that this structure reduces the requirements for materials and molding equipment. The expansion amount of the second connecting section 10e of the laundry treatment drum 10 is less than that of the drum body 10b, and the wrinkles and cracks of the second connecting section 10e are relatively small, that is, the surface of the second connecting section 10e can be made relatively flat and smooth, which is conducive to reducing the resistance of the laundry treatment drum 10 during the rotation process and can reduce the abnormal noise generated by the laundry treatment drum 10 during the rotation process. Even if there are slight wrinkles and unevenness on the surface of the first connecting section 10d, the effect on the adhesion of the felt is relatively small.

[0067] In other embodiments, the cylindrical clothing treatment drum 10 is made of metal steel plates such as stainless steel or the like. Specifically, the metal steel plates such as stainless steel or the like are first rolled into a cylindrical shape and then the connecting portions where the steel plates are in contact are welded to form the cylindrical clothing treatment drum 10. Then, both ends of the clothing treatment drum 10 are contracted inward to form a contraction portion. Specifically, the clothing treatment drum 10 is first contracted inward by a certain distance to form a second connecting segment 10e. Then, the clothing treatment drum 10 is further contracted inward by a certain distance on the basis of the second connecting segment 10e to form a first connecting segment 10d. In this way, a contraction section 10c is formed, including the clothing treatment drum 10 having the first connecting segment 10d and the second connecting segment 10e, and the outer diameter of the barrel body 10b is larger than the outer diameter of the second connecting segment 10e, and the outer diameter of the second connecting segment 10e is larger than the outer diameter of the first connecting segment 10d.

[0068] Similarly, this structure also reduces the requirements for materials and molding equipment. The shrinkage of the second connecting section 10e of the laundry treatment drum 10 is less than that of the first connecting section 10d, and the wrinkles and cracks of the second connecting section 10e are less, that is, the surface of the second connecting section 10e can be made flatter and smoother, which is conducive to reducing the resistance of the laundry treatment drum 10 during rotation and can reduce the abnormal noise generated during rotation of the laundry treatment drum 10. Even if the surface of the first connecting section 10d has slight wrinkles and unevenness, it has little effect on the adhesion of the felt.

[0069] The laundry treatment drum 10 provided in the embodiment of the present application includes a barrel 10b and a contraction section 10c. On the one hand, by setting the laundry treatment drum 10 as an integrated structure, it is beneficial to reduce parts, improve manufacturing efficiency, and reduce manufacturing costs. On the other hand, by setting the contraction section 10c to include a first connecting section 10d and a second connecting section 10e, the first connecting section 10d is located at the end of the second connecting section 10e away from the barrel 10b, and the outer diameter of the first connecting section 10d is smaller than the outer diameter of the second connecting section 10e, that is, the laundry treatment drum 10 adopts a two-stage step-type contraction at the end of the barrel, so that the laundry treatment drum 10 can meet the requirements of connecting with other parts through the first connecting section 10d, and can also include a second connecting section 10e with a smaller contraction size radially inward relative to the barrel 10b, further reducing the molding difficulty, and to a certain extent, it is beneficial to ensure the flatness of the second connecting section 10e, so that the resistance and noise of the laundry treatment drum 10 during the rotation process can be reduced through the roller support and drive cooperation of the second connecting section 10e and the driving assembly. That is to say, the clothing processing drum 10 provided in the embodiment of the present application improves manufacturing efficiency, reduces manufacturing cost and molding difficulty, and can also reduce the resistance and noise of the clothing processing drum 10 during rotation. In addition, it is also beneficial to increase the volume of the clothing processing chamber 10a.

[0070] In some embodiments, the difference between the outer diameter of the barrel 10b and the outer diameter of the second connecting section 10e is 7mm-15mm. In other words, the shrinkage amount of the second connecting section 10e relative to the barrel 10b is 7mm-15mm.

[0071] For example, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm and so on.

[0072] By setting the difference between the outer diameter of the barrel 10b and the outer diameter of the second connecting section 10e to 7mm-15mm, on the one hand, the second connecting section 10e is contracted inward by a certain distance, which is conducive to meeting the cooperation with the roller assembly 40. In addition, the contraction amount of the second connecting section 10e relative to the barrel 10b within this range can also make the surface of the second connecting section 10e relatively flat and smooth, which is conducive to reducing the resistance of the laundry treatment barrel 10 during the rotation process and can reduce the abnormal sound generated by the laundry treatment barrel 10 during the rotation process. Furthermore, relative to the contraction amount of the first connecting section 10d, the contraction amount of the second connecting section 10e relative to the barrel 10b within this range is also conducive to increasing the volume of the laundry treatment chamber 10a.

[0073] In some embodiments, the difference between the outer diameter of the second connecting section 10e and the outer diameter of the first connecting section 10d is 5mm-10mm. In other words, the shrinkage of the first connecting section 10d relative to the second connecting section 10e is 5mm-10mm, and the shrinkage of the first connecting section 10d relative to the barrel 10b is 12mm-25mm.

[0074] For example, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm and so on.

[0075] By setting the difference between the outer diameter of the second connecting segment 10e and the outer diameter of the first connecting segment 10d to 5mm-10mm, on the one hand, the first connecting segment 10d shrinks inward by a certain distance, which is conducive to the adhesion cooperation with the felt and the cooperation with the front support 30. In addition, the shrinkage amount of the first connecting segment 10d relative to the second connecting segment 10e within this range makes it less affected to the adhesion of the felt even if there are slight wrinkles and unevenness on the surface of the first connecting segment 10d.

[0076] Here, the axial direction of the barrel 10b is Figure 2 The dimension of the first connecting section 10d along the axial direction of the barrel 10b is represented by Figure 3 The dimension of the second connecting section 10e along the axial direction of the barrel 10b is Figure 3 Indicated by L2.

[0077] In some embodiments, see Figure 2 and Figure 3 The axial dimension of the first connecting section 10d along the barrel 10b is 5mm-15mm.

[0078] For example, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm and so on.

[0079] Here, if the axial dimension of the first connecting section 10d along the barrel 10b is greater than 15 mm, the volume of the clothing treatment barrel 10 will be reduced. If the axial dimension of the first connecting section 10d along the barrel 10b is less than 5 mm, the contact area between the first connecting section 10d and the felt will be reduced, thereby reducing the bonding strength between the first connecting section 10d and the felt, and will not be detrimental to the coordination between the clothing treatment barrel 10 and the front support 30.

[0080] In this embodiment, by setting the axial dimension of the first connecting section 10d along the barrel body 10b to 5mm-15mm, it is possible to ensure that the clothing treatment barrel 10 has a certain volume, and also allow the first connecting section 10d and the felt to have a certain contact area, thereby allowing the first connecting section 10d and the felt to have a certain bonding strength, and facilitating the coordination between the clothing treatment barrel 10 and the front support 30.

[0081] It should be noted that the axial dimension of the second connecting section 10e along the barrel 10b is not limited as long as it can cooperate with the roller assembly 40.

[0082] In some embodiments, see Figure 2 and Figure 3 The axial dimension of the second connecting section 10e along the barrel 10b is greater than or equal to 5 mm.

[0083] It can be understood that the smaller the axial size of the second connecting section 10e along the barrel 10b, the larger the volume of the clothing processing barrel 10; however, if the space is too small, it will be unfavorable for the roller assembly 40 to be supported on the second connecting section 10e; and if the axial size of the second connecting section 10e along the barrel 10b is larger, the volume of the clothing processing barrel 10 will be reduced.

[0084] In this embodiment, by setting the axial dimension of the second connecting section 10e along the barrel 10b to be greater than or equal to 5 mm, it is facilitated to achieve the cooperation with the roller assembly 40.

[0085] In some embodiments, see Figure 2 and Figure 3 The contraction section 10c further includes a first transition section 10f, and both ends of the first transition section 10f are smoothly connected to the first connecting section 10d and the second connecting section 10e respectively.

[0086] That is to say, the first connecting section 10d and the second connecting section 10e are smoothly connected via the first transition section 10f to achieve a smooth transition.

[0087] In this embodiment, the first transition section 10f is provided to ensure a smooth connection between the first connecting section 10d and the second connecting section 10e, which helps to reduce the difficulty of molding and improve the surface flatness of the first connecting section 10d and the second connecting section 10e.

[0088] In some embodiments, please refer to Figure 2 and Figure 3 The contraction section 10c also includes a second transition section 10h, and both ends of the second transition section 10h are smoothly connected to the barrel 10b and the second connecting section 10e respectively.

[0089] That is to say, the barrel 10b and the second connecting section 10e are smoothly connected via the second transition section 10h to achieve a smooth transition.

[0090] In this embodiment, a second transition section 10h is provided to achieve a smooth connection between the barrel body 10b and the second connecting section 10e, which helps to reduce the difficulty of molding and improve the surface flatness of the second connecting section 10e, thereby helping to reduce the resistance of the clothing processing barrel 10 during rotation and reduce the abnormal noise generated by the clothing processing barrel 10 during rotation.

[0091] In some embodiments, please refer to Figure 2 and Figure 3 One end of the first connecting section 10d away from the second connecting section 10e is folded outward to form a flange 10n, and the flange 10n is in contact with the first connecting section 10d.

[0092] Exemplarily, by performing a curling process of bending at both ends of the laundry treatment drum 10 in the axial direction, flanges 10n are stacked on the periphery of both ends of the laundry treatment drum 10 in the axial direction, that is, the flanges 10n are in contact with the first connecting section 10d.

[0093] In this embodiment, the clothing treatment drum 10 is folded at both ends along the axial direction to form flanges 10n. This is helpful in improving the problem of sharp burrs at the end of the clothing treatment drum 10. To a certain extent, it can avoid the injury to operators caused by the sharp burrs at the end of the clothing treatment drum 10 during the production, assembly or transfer of the clothing treatment drum 10, and can improve the problem of damage to the felt.

[0094] In some embodiments, the laundry processing apparatus 100 further includes a driving assembly, at least a portion of which is in contact with the second connecting section 10 e and is used to drive the laundry processing drum 10 to rotate.

[0095] For example, see Figure 3 The driving assembly includes a motor, a belt and a roller assembly 40. The roller assembly 40 is used to support the clothing treatment drum 10. The motor drives the clothing treatment drum 10 to rotate through the belt transmission.

[0096] In this embodiment, by setting the contraction section 10c of the clothing treatment drum 10 to include a first connecting section 10d and a second connecting section 10e, the first connecting section 10d is located at the end of the second connecting section 10e away from the drum body 10b, and the outer diameter of the first connecting section 10d is smaller than the outer diameter of the second connecting section 10e. In this way, the wrinkles, weld cracks and other problems of the second connecting section 10e can be reduced, that is, the surface of the second connecting section 10e can be made flatter and smoother, which is beneficial to reduce the resistance of the clothing treatment drum 10 during the rotation process, and can reduce the abnormal noise generated by the clothing treatment drum 10 during the rotation process.

[0097] In some embodiments, see Figure 2 and Figure 3 The clothing processing device 100 further includes a sealing ring 50, which is attached to the first connecting section 10d.

[0098] In this embodiment, by shrinking the first connecting section 10d inward by a certain distance, it is beneficial to meet the adhesion cooperation with the felt and the cooperation with the front support 30, and even if the surface of the first connecting section 10d has slight wrinkles and unevenness, the impact on the adhesion of the felt is relatively small.
