[0066] As Figures 1 to 14 shown, the embodiments of the present application provide a clothes treatment device including a cabinet 10, a drum 20, a support assembly 30 and a rotating member 40. In addition, the clothes treatment device is a washing machine, a drying machine, a washer-dryer or other washing device provided with the drum 20, and the type of the clothes treatment device is not specifically limited here.
[0067] The cabinet 10 includes a front support plate 11 and a rear support plate 12, and has an accommodation space 13 between the front support plate 11 and the rear support plate 12, and the front support plate 11 is provided with a drop port 111 and a connecting hole 112; the cabinet 10 is used to constitute the overall appearance of the clothes treatment device, and support the internal parts of the clothes treatment device. The front support plate 11 is generally made of non-metallic material.
[0068] The drum 20 is arranged in the accommodating space 13 and rotatably connected with the rear support plate 12. The drum 20 has a cavity 22 with an opening 21, and the opening 21 is communicated with the feeding opening 111. Specifically, the drum 20 is in a cylindrical shape, the front side of the drum 20 is open to form a barrel opening (the barrel opening is the opening 21 of the cavity 22), and clothes are fed into the drum 20 from the barrel opening. The rear end of the drum 20 is a closed end to prevent clothes from falling out of the drum 20. The front support plate 11 is arranged on the front side of the drum 20, and the rear support plate 12 is arranged on the rear side of the drum 20. The clothes are continuously tumbled by rotating the drum 20 to process the clothes.
[0069] The support assembly 30 is arranged in the accommodating space 13 and mounted on the front support plate 11, and the end of the drum 20 is pressed against the support assembly 30. Generally, the left and right sides of the front end of the drum 20 are respectively provided with a support assembly 30.
[0070] The support assembly 30 includes a framework 31, a damping ring 32, and a connecting shaft 33.
[0071] The framework 31 is generally made of non-metallic materials such as polypropylene, polypropylene plus glass fiber, and nylon. The shape of the framework 31 can be various forms, which are not limited here.
[0072] The damping ring 32 is sleeved on the framework 31 and in contact with the drum 20. The damping ring 32 can be made of rubber or polyurethane. The shape of the damping ring 32 can be various forms, which are not limited here. The damping ring 32 and the framework 31 are partially fused, and the greater the contact area between the two components, the better. Specifically, one of the damping ring 32 and the framework 31 is provided with a groove, and the other is provided with a protrusion.
[0073] One end of the connecting shaft 33 is fixedly connected with the framework 31, and the connecting shaft 33 is generally made of metal materials such as steel.
[0074] The rotating member is arranged on the hole wall of the connecting hole and can rotate relative to the front support plate. The other end of the connecting shaft is connected with the rotating member, and the rotating member is configured to enable the connecting shaft to rotate relative to the front support plate.
[0075] During the rotation of the drum, the drum will exist forward and backward movement and other direction offset movement, so the support assembly is also subjected to the force from the drum in different directions, in the prior art, one end of the connecting shaft is rotatably connected with the framework through a bearing, the other end of the connecting shaft is fixedly connected with the front support plate, when the framework is subjected to external force, since the bearing needs to transmit the external force to the connecting shaft, the bearing will interfere with the force transmission, so that the force transmission between the framework and the connecting shaft is easy to disperse, which leads to uneven force transmission between the framework and the connecting shaft and easy stress concentration, in addition, since the support assembly will be subjected to the frequent action of the drum, alternating stress will be generated on the framework, according to the fatigue theory, when the alternating stress exceeds the fatigue limit of the material, the framework will gradually produce fatigue damage, and finally lead to cracking.
[0076] In addition, the connecting shaft is fixedly connected with the front support plate, since the rigidity of the front support plate is far less than that of the connecting shaft, in the process of force transmission, if the front support plate does not have enough bending resistance or does not have reasonable support point distribution to resist the bending moment, stress is easy to concentrate in the part where the connecting shaft and the front support plate contact, which leads to that the front support plate locally bears large pressure, the front support plate will deform greatly, so that the connecting shaft will be offset, and also leads to that the force cannot be uniformly transmitted between the connecting shaft and the front support plate, and local force concentration phenomenon may be generated on the front support plate, so that the front support plate appears deformation, cracking and other problems, which affects the rotation of the support assembly.
[0077] The laundry treating apparatus provided in the application, the connecting shaft 33 is directly connected with the framework 31, that is, the connecting shaft 33 and the framework 31 can be regarded as a relatively rigid whole, the force acting on the support assembly 30 by the drum 20 is directly transmitted from the framework 31 to the connecting shaft 33, that is, there is no intermediate complex connecting component between the connecting shaft 33 and the framework 31 to interfere with the force transmission process, so that the framework 31 will not shake due to the deformation of the connecting component and other conditions, so that the support assembly 30 can better bear the force, thereby reducing the probability of deformation or fracture of the framework 31, to improve the use reliability of the support assembly 30.
[0078] In addition, the connecting shaft 33 is rotatably connected with the front support plate 11 through the rotating piece 40. Since the rigidity of the connecting shaft 33 and the rotating piece 40 is similar, the deformation difference between the connecting shaft 33 and the rotating piece 40 is similar during force transmission, so that the connecting shaft 33 and the rotating piece 40 can be better fitted. On the one hand, the gap or interference caused by the large deformation difference between the components is reduced, so that the force received by the connecting shaft 33 is uniformly distributed to the front support plate 11, avoiding the problems of deformation, cracking and the like of the front support plate 11 caused by excessive local stress, which affects the perpendicularity of the front support plate 11 and the connecting shaft 33. On the other hand, the rotating piece 40 plays a role in dispersing stress, so that the force on the connecting shaft 33 is more uniformly transmitted to the front support plate 11, reducing the stress concentration degree and reducing the risk of damage to the front support plate 11 caused by stress concentration, improving the stability and reliability of the overall structure. Therefore, the connecting shaft 33 is rotatably connected with the front support plate 11 through the rotating piece 40, and the rotating piece 40 can provide more stable support for the connecting shaft 33 relative to the front support plate 11, which helps to reduce the vibration and noise caused by the shaking of the connecting shaft 33, so as to ensure the stability of the rotation of the support assembly 30.

The front support plate 11 is provided with a feeding opening 111 and a connecting hole 112. The cabinet 10 is used to constitute the overall appearance of the laundry treatment device and support the internal components of the laundry treatment device. The front support plate 11 is generally made of a non-metallic material.
[0081] The drum 20 is rotatably arranged in the cabinet 10, and an opening 21 of the drum 20 faces the front support plate 11. Specifically, the drum 20 is arranged in the containing space 13 and rotatably connected with the rear support plate 12. The drum 20 has a containing cavity 22 with one end being the opening 21, and the opening 21 is in communication with the feeding opening 111. Specifically, the drum 20 is cylindrical, the front side of the drum 20 is open to form a cylinder opening (the cylinder opening is the opening 21 of the containing cavity 22), clothes are fed into the drum 20 from the cylinder opening, and the rear end of the drum 20 is a closed end to prevent clothes from falling out of the drum 20. The front support plate 11 is arranged at the front side of the drum 20, and the rear support plate 12 is arranged at the rear side of the drum 20.

[0083] The support assembly 30 comprises a mounting frame 34 and a damping ring 32.
[0084] The damping ring 32 is sleeved on one end of the mounting frame 34 and is in contact with the roller 20. The damping ring 32 can be made of rubber or polyurethane, and the shape of the damping ring 32 can be various forms, which are not limited here; the damping ring 32 is partially integrated with the mounting frame 34, and the greater the contact area between the two components, the better; specifically, one of the damping ring 32 and the mounting frame 34 is provided with a groove, and the other is provided with a protrusion.

[0086] The laundry treating apparatus provided in the present application has the mounting frame 34 as a rigid whole, and the force acting on the support assembly by the roller is directly applied to the mounting frame, so that the support assembly can better withstand the force, thereby reducing the probability of damage to the mounting frame 34 and improving the use reliability of the support assembly; in addition, the mounting frame is rotatably connected with the front support plate, so that the rotating piece can uniformly distribute the force received by the mounting frame to the front support plate, avoiding the problems of deformation and cracking of the front support plate due to excessive local stress, thereby affecting the perpendicularity of the front support plate to the mounting frame, thereby helping to reduce the vibration and noise generated due to the shaking of the connecting shaft, so as to ensure the stability of the rotation of the support assembly.
[0087] In addition, the rotating piece 40 plays a role in dispersing stress, and the force on the mounting frame 34 is more uniformly transmitted to the front support plate 11, reducing the degree of stress concentration and reducing the risk of damage to the front support plate 11 due to stress concentration, improving the stability and reliability of the overall structure, and helping to reduce the vibration and noise generated due to the shaking of the connecting shaft 33, so as to ensure the stability of the rotation of the support assembly 30.
[0088] In some embodiments of the present application, the mounting frame 34 comprises a skeleton 31 and a connecting shaft 33.
[0089] The damping ring 32 is sleeved on the skeleton 31 and is in contact with the roller 20; one end of the connecting shaft 33 is rigidly connected with the skeleton 31, so that the connecting shaft 33 and the skeleton 31 can rotate synchronously, and the other end of the connecting shaft 33 is connected with the rotating piece 40.
[0090] The mounting frame 34 is composed of the skeleton 31 and the connecting shaft 33, which can be made of different materials and processes in the manufacturing process, that is, the appropriate materials and manufacturing processes can be selected according to the function and requirements of each part, the manufacturing flexibility is high, and the cost is better controlled; specifically, the skeleton 31 is generally made of non-metallic materials such as polypropylene, polypropylene with glass fiber, nylon, etc., and the shape of the skeleton 31 can be in various forms, which will not be specifically limited here. The connecting shaft 33 is generally made of metal materials such as steel.
[0091] The connecting shaft 33 is directly connected with the skeleton 31, that is, the connecting shaft 33 and the skeleton 31 can be regarded as a relatively rigid whole, the force acting on the supporting assembly 30 by the roller 20 is directly transmitted from the skeleton 31 to the connecting shaft 33, that is, there is no intermediate complex connecting component between the connecting shaft 33 and the skeleton 31 to interfere with the force transmission process, so that the skeleton 31 will not shake due to the deformation of the connecting component, etc., so that the supporting assembly 30 can better withstand the force, thereby reducing the probability of deformation or fracture of the skeleton 31, to improve the use reliability of the supporting assembly 30.
[0092] In addition, the connecting shaft 33 is rotatably connected with the front support plate 11 through the rotating piece 40, since the rigidity of the connecting shaft 33 and the rotating piece 40 is similar, the deformation difference between the connecting shaft 33 and the rotating piece 40 is similar in the force transmission process, so that the connecting shaft 33 and the rotating piece 40 can better fit, reducing the gap or interference caused by the large deformation difference between the components, so that the force received by the connecting shaft 33 is evenly distributed to the front support plate 11, avoiding the problem that the front support plate 11 is deformed, cracked, etc. due to excessive local stress, thereby affecting the perpendicularity of the front support plate 11 and the connecting shaft 33.
