[0035] The embodiments of the present application will be further described below in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0036] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "top", "bottom", "height direction" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", "third" and the like are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0037] The present application provides a drum assembly, please refer to Figure 1 and Figure 3 , comprising at least two drum assemblies 1 spaced apart in the height direction and a damping device 2 connected between adjacent two drum assemblies 1.

[0038] Illustratively, the damping device 2 bears the drum assembly 1 located above. That is to say, between the adjacent two drum assemblies 1, the drum assembly 1 located above is supported on the drum assembly 1 located below by the damping device 2, that is to say, the damping device 2 has a certain supporting capacity and can bear the weight of the drum assembly 1.

[0039] In the embodiments of the present application, the plurality means no less than two. The number of drum assemblies 1 can be two, three or more. Illustratively, in the embodiments of the present application, the number of drum assemblies 1 is taken as two for illustration.

[0040] The drum assembly 1 has a clothes treatment cavity, and the front side of the clothes treatment cavity is open to form a clothes loading / unloading opening.

[0041] Illustratively, the drum assembly 1 includes an outer tub 11 and an inner tub rotatably arranged in the outer tub 11, and the space in the inner tub is the clothes treatment cavity.

[0042] The inner tub can be a perforated inner tub, i.e., the inner tub is filled with water by the outer tub 11; the inner tub can also be a non-perforated inner tub, i.e., the inner tub itself can hold water, and during the washing of laundry, washing water will not enter the outer tub 11. Of course, during the laundry treatment process, the partial tub assembly 1 can not need to be filled with water, for example, the partial tub assembly 1 only has a drying function and does not have a washing function.

[0043] It should be noted that, Figure 1 and Figure 3 only shows part of the structure of the outer tub 11.

[0044] The laundry treatment device provided by the embodiments of the present application comprises a cabinet and the tub assembly assembly of any of the embodiments of the present application, and the tub assembly assembly is arranged in the cabinet.

[0045] The laundry treatment device provided by the embodiments of the present application has multiple partial tub assemblies 1 integrated along the height direction, thereby improving the integration of the laundry treatment device and saving indoor area.

[0046] The functions of the partial tub assemblies 1 can be the same or different, which is not limited herein. For example, the lower partial tub assembly 1 is used for washing or dewatering, and the upper partial tub assembly 1 is used for drying laundry, etc.

[0047] Please refer to Figure 2 , Figure 5 to Figure 8 , the damping device 2 comprises a mass block 23, a conversion mechanism 22, and at least two connecting members 21. Please refer to Figure 2 and Figure 4 , one of the connecting members 21 is connected with the upper partial tub assembly 1, and exemplarily, the connecting member 21 is hinged with the outer tub 11, and the connection point is marked as D1; the other connecting member 21 is connected with the lower partial tub assembly 1, and exemplarily, the connecting member 21 is hinged with the outer tub 11, and the connection point is marked as D2.

[0048] The conversion mechanism 22 is connected between the two connecting members 21, i.e., the two connecting members 21 are connected through the conversion mechanism 22, the two connecting members 21 are arranged in a spaced manner and do not interfere with each other, and the two connecting members 21 are connected through the conversion mechanism 22 to realize the correlation of the motion relationship and the transmission of the force. It should be noted that the connecting member 21 is a rigid member, and the length thereof will not change, and can reliably support and transmit the acting force.

[0049] Specifically, the weight of the upper partial tub assembly 1 and the load thereof is transmitted to the conversion mechanism 22 through the upper connecting member 21, and is transmitted to the lower connecting member 21 through the conversion mechanism 22, and is then transmitted to the lower partial tub assembly 1 through the lower connecting member 21.

[0050] The conversion mechanism 22 is adapted to convert the relative motion between the two adjacent partial tub assemblies 1 into the motion of the mass block 23.

[0051] It should be noted that each drum assembly 1 serves as a vibration source, and the drum assembly 1 vibrates to drive the connecting member 21 to vibrate, and the connecting member 21 vibrates to generate displacement changes in the up-down direction. During this process, the support length H1 (see FIG. 2) of the damping device 2 changes to adapt to the distance change between the adjacent two drum assemblies 1 in the up-down direction. Figure 2 ) changes to adapt to the distance change between the adjacent two drum assemblies 1 in the up-down direction.

[0052] When the drum assembly 1 vibrates, the distance between the adjacent two drum assemblies 1 in the up-down direction is in a dynamic change process, and the distance between the connecting point D1 and the connecting point D2 changes synchronously. That is, the distance change value between the two drum assemblies 1 in the up-down direction and the distance change value between the connecting point D1 and the connecting point D2 are the same. For example, if the distance between the two drum assemblies 1 in the up-down direction increases by 1 cm, the distance between the connecting point D1 and the connecting point D2 also increases by 1 cm. For ease of description, the distance change value between the connecting point D1 and the connecting point D2 is used as an example to describe the distance change value between the adjacent two drum assemblies 1.

[0053] It should be noted that the support length H1 of the damping device 2 refers to the distance between the connecting point D1 and the connecting point D2.

[0054] In the related art, the two drum assemblies adjacent in the up-down direction are independently mounted on the cabinet, and the two drum assemblies independently vibrate, and the vibrations of the two drum assemblies do not constrain each other, and the vibration frequencies do not affect each other. When the two drum assemblies are both in high-speed rotation, for example, in a dehydration working condition, the two drum assemblies vibrate together, which is easy to produce resonance, resulting in a large exciting force transmitted from the bottom feet of the laundry treatment apparatus to the ground.

[0055] In the embodiment of the present application, the damping device 2 reliably connects the two drum assemblies 1 together, and the vibrations of the two drum assemblies 1 can constrain each other, and any one drum assembly 1 will inhibit and constrain the vibration of the other drum assembly 1. In addition, the weight of the upper drum assembly 1 is transmitted to the lower drum assembly 1, and the weight of the upper drum assembly 1 acts as a counterweight for the lower drum assembly 1, further improving the vibration performance of the lower drum assembly 1 and reducing the exciting force transmitted from the bottom feet of the cabinet to the ground.

[0056] In the vibration process of the cartridge assembly 1, the conversion mechanism 22 converts the relative movement between the two adjacent cartridge assemblies 1 into the movement of the mass block 23, the mass block 23 has a large moment of inertia, the moment of inertia of the mass block 23 acts on the conversion mechanism 22, and a certain damping effect is generated, thereby hindering the change of the distance between the two connecting members 21, and further playing a role in inhibiting the amplitude of the two adjacent cartridge assemblies 1; in addition, the vibration energy of the cartridge assembly 1 can be consumed in the movement process of the mass block 23, thereby playing a role in quickly absorbing vibration, reducing the vibration energy transmitted from the cartridge assembly 1 to the box, and reducing the excitation force transmitted from the bottom foot of the box to the ground.

[0057] The movement form of the mass block 23 is not limited, for example, can be linear motion, rotary motion, etc.

[0058] The specific structure of the conversion mechanism 22 is not limited.

[0059] Exemplarily, the conversion mechanism 22 includes a translating member connected with the connecting member 21, and a rotating member rotationally matched with the translating member. The conversion mechanism 22 can convert the translation of the two connecting members 21 into the rotary motion of the rotating member. The mass block 23 is connected to the rotating member to follow the rotation of the rotating member, that is, the rotating member drives the mass block 23 to rotate together.

[0060] The cartridge assembly of the embodiment of the present application, the rotation of the rotating member is not only positively related to the distance between the two cartridge assemblies 1, but also positively related to the distance change between the two cartridge assemblies 1, that is, related to the vibration frequency of the two cartridge assemblies 1. When the distance between the two cartridge assemblies 1 changes faster, that is, the vibration frequency of the cartridge assembly 1 is larger, the rotating member rotates faster, the mass block 23 rotates faster, and the vibration energy consumed is more. The vibration energy of the cartridge assembly 1 can be quickly consumed to achieve the effect of quickly absorbing vibration. When the distance between the two cartridge assemblies 1 changes slowly, the rotating member rotates slowly, and the mass block 23 also rotates slowly, which can adaptively consume the vibration energy of the cartridge assembly 1. As can be seen, the cartridge assembly of the embodiment of the present application, the vibration absorbing frequency band of the damping device is not limited, and the cartridge assembly 1 has a good vibration absorbing effect in the whole vibration frequency band.

[0061] In the related art, a spring is used to damp the cartridge assembly, but the vibration absorbing energy of the spring is only related to the amplitude of the cartridge assembly, and cannot adaptively change according to the vibration frequency of the cartridge assembly; in addition, the spring can only absorb vibration when it is compressed, and in this process, the spring stores elastic potential energy, and when the cartridge assembly 1 moves in the opposite direction, the spring releases the elastic potential energy, which acts on the cartridge assembly 1 and plays a role in boosting the cartridge assembly 1 to move in the opposite direction. Furthermore, the spring can easily cause the cartridge assembly 1 and the box to resonate.

[0062] The damping assembly can absorb vibration and dampen when the distance between the two drum assemblies 1 increases or decreases during the vibration process of the drum assembly. Specifically, taking forward rotation of the rotating member as an example, the mass block 23 rotates forward and consumes energy when the distance between the two drum assemblies 1 gradually decreases. When the distance between the two drum assemblies 1 gradually increases, the rotating member reverses, and the mass block 23 also reverses, and the mass block 23 also consumes energy. That is, the mass block 23 is always in a state of consuming energy, which can better dampen the drum assembly 1, reduce the excitation force transmitted to the cabinet by the drum assembly, and further reduce the excitation force transmitted to the ground by the cabinet.

[0063] Exemplarily, the clothes treatment apparatus includes a plurality of dampers and a plurality of hangers. The lowermost drum assembly 1 is supported on the bottom of the cabinet by the dampers, and the uppermost drum assembly 1 is hung on the cabinet by the hangers. That is, the drum assembly can be assembled in the cabinet by the hangers and the dampers.

[0064] The lowermost drum assembly 1 refers to the lowermost drum assembly 1 among all drum assemblies 1 arranged in the height direction. The uppermost drum assembly 1 refers to the uppermost drum assembly 1 among all drum assemblies 1 arranged in the height direction.

[0065] It should be noted that the damper can be any structure of the damper in the prior art, which will not be described here. The hanger can also be any structure of the hanger in the prior art, which will not be described here.

[0066] It should be noted that the hanger bears tension. On the one hand, the hanger bears part of the gravity of the drum assembly and its load, and on the other hand, the hanger plays a role of installing and positioning the drum assembly, and connects the drum assembly to a suitable position on the upper part of the cabinet.

[0067] The clothes treatment apparatus of the embodiment of the present application integrates all drum assemblies 1 into a drum assembly, the vibration of each drum assembly 1 is restricted by each other, and the amplitude can be restricted by each other. The whole is connected to the cabinet by the dampers and the hangers. The dampers and the hangers themselves have a certain damping effect, which reduces the amplitude of the cabinet, further reduces the excitation force transmitted to the cabinet by the drum assembly, and reduces the excitation force transmitted to the ground by the cabinet.

[0068] Exemplarily, the drum assembly is connected to the cabinet only by the dampers and the hangers. In this way, the structure of the clothes treatment apparatus can be simple and compact.

[0069] It should be noted that the number of damping devices 2 between the two adjacent drum assemblies 1 is not limited and can be one or two.

[0070] For example, referring to Figure 1 and Figure 3 , the number of the damping devices 2 is multiple, and at least two damping devices 2 are arranged side by side along the left-right direction of the barrel assembly.

[0071] For example, the center of gravity of the mass block 23 is located on the rotation axis of the rotating member, so that the mass block 23 can avoid causing severe vibration when rotating. It should be noted that the center of gravity of the mass block 23 can be determined by the suspension method in the prior art, which will not be described here.

[0072] The specific shape of the mass block 23 is not limited. For example, it can be disc-shaped, cylindrical, impeller-shaped, etc.

[0073] For example, the mass block 23 is a flywheel, that is, the cross-sectional shape of the mass block 23 in the projection perpendicular to the rotation axis of the rotating member is circular. The flywheel is coaxially arranged with the rotating member. The material of the flywheel is not limited, which can be metal, inorganic non-metal, etc. as long as the mass block 23 has a large moment of inertia.

[0074] For example, referring to Figure 2 , Figure 4 , Figure 5 to Figure 8 , one of the translating member and the rotating member is the nut assembly 222, and the other is the screw rod 221. The nut assembly 222 has a threaded hole, and the screw rod 221 is rotatably arranged in the threaded hole of the nut assembly 222.

[0075] Specifically, when the translating member is the nut assembly 222 and the rotating member is the screw rod 221, the nut assembly 222 does not rotate, and the screw rod 221 rotates. When the translating member is the screw rod 221 and the rotating member is the nut assembly 222, the screw rod 221 does not rotate, and the nut assembly 222 rotates.

[0076] In this embodiment, during the axial relative movement of the screw rod 221 and the nut assembly 222, the screw rod 221 or the nut assembly 222 rotates, thereby realizing the conversion of the translation of the connecting member 21 into the rotation of the rotating member, and the structure is simple and the movement mode is reliable.

[0077] The specific structure of the nut assembly 222 is not limited. For example, in some embodiments, the screw rod 221 and the nut assembly 222 can be a common screw and slider structure.

[0078] In other embodiments, a spiral groove is formed on the surface of the screw 221, and a ball is disposed within the nut assembly 222 for rolling engagement with the spiral groove. The nut assembly 222 and the screw 221 form a ball screw pair. The ball screw pair has low friction resistance, allowing the screw 221 or the nut assembly 222 to rotate smoothly. In addition, the ball screw pair has the characteristics of high precision, reversibility, and high efficiency, which can further enhance the vibration reduction performance of the vibration reduction device.

[0079] It should be noted that the circulation method of the balls on the nut assembly 222 is not limited. It can adopt an internal circulation method or an external circulation method, and there is no limitation here.

[0080] The mass block 23 can be directly fixed to the rotating member, for example, by bolts, bolt nails, welding, etc.; it can also be indirectly fixed to the rotating member through other structures.

[0081] For example, see Figure 2 、 Figure 4 、 Figure 5 to Figure 8 The vibration damping device 2 includes a mounting base 24, which is connected to the rotating member, and a mass block 23 is detachably connected to the mounting base 24. In other words, the mass block 23 is not directly connected to the rotating member, but is indirectly assembled to the rotating member through the mounting base 24. In this way, for different models of clothing processing equipment, the vibration damping device 2 only needs to be equipped with mass blocks 23 with different rotational inertias. The connecting member 21, nut assembly 222, screw 221, and mounting base 24 can all be used universally, and the mounting base 24 serves as a transfer. This can improve the commonality of parts between different models of clothing processing equipment and reduce the pressure of parts inventory.

[0082] The specific structure of the connecting member 21 is not limited. The connecting member 21 can be an integrally formed structure or can be assembled from multiple parts.

[0083] For example, see Figure 8 、 Figure 5 and Figure 6 The connecting member 21 includes a connecting rod 211 and a support frame 212 disposed at an end of the connecting rod 211 away from the barrel assembly 1. The connecting member 21 is connected to the translation member via the support frame 212. The specific connection method between the support frame 212 and the connecting rod 211 is not limited, as long as the two can be reliably connected together, for example, by bolts, welding, etc.

[0084] The interior of the connecting rod 211 can be hollow, solid, or partially hollow, and there is no limitation here, as long as its structural strength meets the requirements.

[0085] Exemplarily, the connecting rods 211 of the two connecting members 21 are arranged along the same line, and the screw rod 221 is parallel to the connecting rods 211, that is, the screw rod 221 is arranged staggered with the two connecting rods 211, so that the installation space required by the vibration damping device in the up-down direction can be saved.

[0086] Exemplarily, the connecting rod 211 is hinged to the drum 1, and the axis of the hinge is along the front-rear direction of the clothes treatment apparatus. For example, referring to Figure 8 , the connecting rod 211 is provided with a first connecting hole 211a at one end, referring to Figure 5 to Figure 8 and Figure 2 , the surface of the outer tub 11 is provided with a support 111, the support 111 is provided with a second connecting hole 111a, and the connecting shaft is arranged in the first connecting hole 211a and the second connecting hole 111a, that is, the support 111 and the connecting rod 211 are hinged.

[0087] The following is an exemplary description of several specific embodiments of the vibration damping device of the present application.

[0091] The screw rod 221 passes through the first bearing 26, and the stopper 25 is located on the side of the first bearing 26 away from the nut assembly 222 and abuts against the first bearing 26, so as to prevent the screw rod 221 from being separated from the first bearing 26 in the axial direction.

[0098] It can be understood that in other embodiments, the mass block 23 can also be arranged on the side of the nut assembly 222 away from the first bearing 26, that is, in the same embodiment, the mass block 23 can be arranged on both ends of the screw rod 221.

[0100] The nut assembly 222 is a rotating member, and the screw rod 221 is a translational member.
