Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and specifically provides a clothing processing device. Background Art

[0002] With the increasing maturity of production technology and the continuous improvement of people's living standards, various clothing processing equipment has emerged. The most common clothing processing equipment includes washing machines, dryers, and clothing sterilizers. Taking a washing machine as an example, a washing machine can wash clothes through mechanical action. Specifically, the washing machine includes an outer drum and an inner drum that is rotatably arranged in the outer drum. Since the inner drum will rotate all the time when washing clothes, the washing machine will produce a certain swing, especially when the inner drum is in eccentric operation. This swing will cause strong vibration, which not only affects the overall performance of the washing machine, but also reduces the user experience. Therefore, when designing a washing machine, it is necessary to reduce the vibration of the washing machine caused by the rotation of the inner drum as much as possible.

[0003] In solving the problem of vibration of clothing processing equipment, still taking the washing machine as an example, in the prior art, a counterweight is generally installed on the outer drum to balance the swing caused by the movement of the washing machine, thereby reducing the vibration of the washing machine. Although this counterweight installation method can make the washing tub (including the outer drum and the inner drum) of the washing machine dynamically balanced as a whole, the eccentric movement of the inner drum of the washing machine during rotation will increase the force between the inner drum and the outer drum, so that the connecting parts between the inner drum and the outer drum are prone to fatigue damage, thereby reducing the service life of the connecting parts. In addition, after long-term use, the operation stability of the washing machine will be reduced due to damage to the connecting parts.

[0004] Therefore, the art needs a new clothes processing device to solve the above problems. Summary of the invention

[0005] In order to solve the above-mentioned problems in the prior art, that is, to solve the problem that the existing clothing processing equipment cannot effectively balance the eccentric rotation of the inner drum by installing a counterweight on the outer drum, the present invention provides a clothing processing equipment, which includes an outer drum and an inner drum rotatably arranged in the outer drum, and the clothing processing equipment also includes a counterweight assembly, which is arranged on the inner drum for balancing the rotation of the inner drum.

[0006] In a preferred technical solution of the above-mentioned clothes processing device, the counterweight assembly is arranged on the inner side of the inner drum.

[0007] In the preferred technical solution of the above-mentioned clothes processing device, the weight assembly is attached to the inner side of the inner drum in a surface contact manner.

[0008] In a preferred technical solution of the above-mentioned clothes processing device, the weight assembly is fixed to the inner side of the inner drum by screws.

[0009] In a preferred technical solution of the above-mentioned clothes processing apparatus, the clothes processing apparatus further comprises a mounting member arranged inside the inner drum, and the counterweight assembly is arranged between the inner drum and the mounting member.

[0010] In a preferred technical solution of the above-mentioned clothes processing device, the mounting member is an attached block arranged in the inner drum, and the attached block is used for friction washing the clothes when the inner drum rotates.

[0011] In a preferred technical solution of the above-mentioned clothes processing device, the weight assembly includes a weight component, a first fixing component and a second fixing component, the weight component is arranged between the first fixing component and the second fixing component, and the second fixing component is arranged on the inner drum.

[0012] In a preferred technical solution of the above-mentioned clothes processing device, the second fixing member is provided with a receiving cavity for receiving the weight component, and the first fixing member is covered on the second fixing member.

[0013] In a preferred technical solution of the above laundry processing apparatus, the weight member includes a plurality of weight plates arranged in a stacked manner.

[0014] In the preferred technical solution of the above-mentioned clothes processing device, the first fixing member and the second fixing member are both made of plastic material.

[0015] It can be understood by those skilled in the art that, in the preferred technical solution of the present invention, by installing the counterweight assembly on the inner drum of the clothing processing device, the rotation of the inner drum can be balanced when the inner drum rotates eccentrically, thereby reducing the force between the inner drum and the outer drum, reducing the fatigue resistance of the connecting parts between the inner drum and the outer drum, and improving the service life of the connecting parts, so that the clothing processing device can maintain its own operating stability for a long time.

[0016] Furthermore, by arranging the weight assembly inside the inner drum, the space between the inner drum and the outer drum is not occupied, thereby facilitating the arrangement and installation of parts of the clothing processing device. The weight assembly is preferably arranged between the attachment block and the inner drum, so that the weight assembly does not occupy the space in the inner drum, which not only does not affect the washing of the clothing, but also achieves the purpose of balancing the eccentric rotation of the inner drum.

[0017] Furthermore, the counterweight assembly is fitted on the inner side of the inner cylinder in a surface contact manner, and then the counterweight assembly is fastened to the inner cylinder by screws. Through such an arrangement, the contact area between the counterweight assembly and the inner cylinder can be increased, and when the inner cylinder rotates, the counterweight assembly will not form a large impact force on the inner side of the inner cylinder to cause deformation of the inner cylinder. Moreover, compared with the technical solution of directly installing by screws using non-surface contact fitting, the present invention can avoid deformation of the connection between the screw and the inner cylinder due to stress concentration caused by screw connection as much as possible through surface contact fitting.

[0018] Furthermore, installing the counterweight assembly on the inner cylinder by screws can avoid mutual force between the counterweight assembly and the auxiliary block, thereby preventing the auxiliary block from being deformed by impact during the rotation of the inner cylinder. Compared with the technical solution of fixing the counterweight assembly to the auxiliary block, the present invention can avoid tensile deformation of the auxiliary block due to the action of the counterweight assembly during high-speed rotation of the inner cylinder.

[0023] First, those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. For example, although the following embodiments are explained in conjunction with a drum washing machine, this is not restrictive, and the technical solution of the present invention is also applicable to other clothing processing equipment, such as a pulsator washing machine, a spin dryer, and a washer-dryer, etc. Such a change in the application object does not deviate from the principle and scope of the present invention.

[0024] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Based on the problem pointed out in the background art that the existing drum washing machine cannot effectively balance the eccentric rotation of the inner drum by installing the counterweight on the outer drum, the present invention provides a drum washing machine, which aims to reduce the force between the inner drum and the outer drum on the basis of balancing the eccentric rotation of the inner drum, thereby reducing the fatigue resistance of the connecting parts of the inner drum and the outer drum, and improving the service life of the connecting parts, so that the drum washing machine can maintain its own operation stability for a long time.

[0027] The present invention provides a drum washing machine, which includes a drum, the drum includes an outer drum and an inner drum rotatably arranged in the outer drum, and the drum washing machine also includes a counterweight assembly, which is arranged on the inner drum to balance the rotation of the inner drum. The counterweight assembly can be arranged on the outside of the inner drum, or on the inside of the inner drum, or a part of the counterweight assembly is arranged on the outside of the inner drum, and the other part is arranged on the inside of the inner drum. Those skilled in the art can flexibly set the installation position of the counterweight assembly in actual applications, as long as the eccentric rotation of the inner drum is balanced by the counterweight assembly.

[0028] It should be noted that the inner drum of the drum washing machine will cause the center of gravity of the inner drum to deviate from the rotation axis of the inner drum due to the installation of different components, so that when the inner drum rotates, the inner drum will rotate eccentrically. Taking a top-opening drum washing machine as an example, the inner drum of the top-opening drum washing machine is generally equipped with a cover body. Due to the existence of the cover body, the center of gravity of the inner drum will shift to one side of the cover body. Therefore, the rotation axis of the inner drum can be used as a symmetry line, and a counterweight assembly can be set on the inner drum at a position symmetrical to the cover body to balance the center of gravity of the inner drum, so that the center of gravity of the inner drum is located on the rotation axis of the inner drum, so that the inner drum will not rotate eccentrically when it rotates. The following takes the drum washing machine as a top-opening drum washing machine, and the counterweight assembly is set on the inner side of the inner drum as an example to explain the technical solution of the present invention in detail.

[0029] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 All of them are schematic diagrams of the structure of the inner drum 1 of the drum washing machine of the present invention. Figure 1 and Figure 2As shown, the drum washing machine includes an inner drum 1, a mounting member arranged on the inner side of the inner drum 1, and a counterweight assembly 3 arranged between the inner side of the inner drum 1 and the mounting member. Among them, the mounting member can be an attachment block 2 arranged in the inner drum 1, and the attachment block 2 can wash the clothes by friction when the inner drum 1 rotates. Through such a setting, the counterweight assembly 3 can fully utilize the space between the attachment block 2 and the inner drum 1, so that the counterweight assembly 3 does not need to occupy other space in the inner drum 1, and will not affect the washing of the clothes in the inner drum 1. Of course, the mounting member can also be other components in the inner drum 1. Those skilled in the art can select any component in the inner drum 1 as the mounting member in actual application, as long as the mounting member can accommodate the counterweight assembly 3 and ensure that the counterweight assembly 3 can balance the eccentric movement of the inner drum 1. The following takes the mounting member as an attachment block 2 as an example to further explain the technical solution of the present invention.

[0030] Preferably, the counterweight assembly 3 is fitted to the inner side of the inner tube 1 in a surface contact manner. For example, when the inner side of the inner tube 1 is a curved surface, the side of the counterweight assembly 3 close to the inner side of the inner tube 1 is set to a curved surface matching the inner side of the inner tube 1, so as to achieve full fit between the counterweight assembly 3 and the inner side of the inner tube 1. Those skilled in the art can flexibly set the shape of the counterweight assembly 3 according to the shape of the inner side of the inner tube 1 in actual applications, as long as the shape setting of the counterweight assembly 3 achieves full fit with the inner side of the inner tube 1. Further preferably, in order to achieve the fastening of the counterweight assembly 3 and the inner tube 1, the counterweight assembly 3 can be fastened to the inner tube 1 by screws. Of course, other fastening methods can also be used to install and fix the counterweight assembly 3, such as bonding, magnetic adsorption and other connection methods. Those skilled in the art can flexibly set the fastening method of the counterweight assembly 3 and the inner tube 1 in actual applications, and the change of this fastening method does not deviate from the technical solution of the present invention.

[0031] Preferably, the counterweight assembly 3 includes a counterweight component 31, a first fixing component 32 and a second fixing component 33. The counterweight component 31 is arranged between the first fixing component 32 and the second fixing component 33, and the second fixing component 33 is arranged on the inner tube 1. Among them, the counterweight component 31 can be a structure such as a counterweight block and / or a counterweight plate. Those skilled in the art can flexibly set the structure of the counterweight component 31 in actual applications, as long as the eccentric movement of the inner tube 1 can be balanced by the counterweight component 31. The clamping of the counterweight component 31 by the first fixing component 32 and the second fixing component 33 can ensure that the counterweight component 31 will not be separated from between the first fixing component 32 and the second fixing component 33. The first fixing component 32 and the second fixing component 33 can be a structure such as a fixing plate and / or a fixing block. Those skilled in the art can flexibly select and set the structure of the first fixing component 32 and the second fixing component 33 in actual applications, as long as the installation of the counterweight component 31 is achieved through the first fixing component 32 and the second fixing component 33. Figure 3As shown, the second fixing member 33 is a box body with a receiving cavity, and the receiving cavity can be used to receive the weight component 31. The second fixing member 33 is a cover body that can be covered on the box body, and the weight component 31 can be prevented from escaping from the receiving cavity by the cover body. The cover body and the box body can be connected by snapping, or the cover body and the box body can be connected by screw connection, or the cover body and the box body can be connected by welding. Those skilled in the art can flexibly set the fixing method of the above-mentioned box body and the cover body in actual applications, as long as the box body and the cover body can be fixedly connected.

[0032] Optionally, the first fixing member 32 and the second fixing member 33 are both made of plastic material. Of course, this is not a limitation, and the first fixing member 32 and the second fixing member 33 can also be made of other materials. Those skilled in the art can flexibly select the materials of the first fixing member 32 and the second fixing member 33 in actual applications, as long as the first fixing member 32 and the second fixing member 33 can be used to install the weight member 31.

[0033] Preferably, the weight member 31 includes a plurality of weight plates arranged in a stacked manner. The weight plates can be connected by screws, or the weight plates can be connected in a stacked manner by bonding. Those skilled in the art can flexibly set the fixing method of the weight plates in actual applications, as long as the weight plates can be connected and installed to each other. Moreover, the structure of the weight plates can flexibly adjust the number of weight plates, thereby adjusting the weight of the weight member 31.
