Description

Technical Field

[0001] The present invention relates to the technical field of clothing processing equipment, and in particular to a cover assembly and clothing processing equipment equipped with the cover assembly. Background Art

[0002] Clothing processing equipment such as washing machines and dryers have become one of the essential household appliances in modern families because they can help users save a lot of manpower and time.

[0003] Take the top-opening drum washing machine as an example, which mainly includes a body, an outer drum, an inner drum, etc. The top of the body is provided with a clothing access opening and a top-opening door that cooperates with the clothing access opening. The outer drum is provided with an outer drum opening at a position aligned with the clothing access opening. Correspondingly, an inner drum opening is provided on the circumference of the inner drum. The inner drum opening is opened or closed by an inner drum cover. The inner drum cover is usually configured as a double-door inner drum cover that can be linked, that is, the two inner drum covers will automatically pop up synchronously when they are unlocked and there is no external force blocking them. Conventionally, the two inner drum covers are connected by a snap-on structure, that is, a hook is provided on one inner drum cover, and a hook hole is provided on the other inner drum cover. After the hook is engaged with the hook hole, the two inner drum covers can be locked.

[0004] In the process of closing the existing inner cylinder cover, the hook and the hook hole are often half-engaged, that is, the hook fails to be completely and tightly engaged in the hook hole. In this state, the inner cylinder cover is easily separated from each other after the inner cylinder runs at high speed, causing serious consequences. To solve this problem, the existing hook is usually provided with a roller-type auxiliary engagement mechanism, which mainly utilizes the rotating characteristics of the roller. When the hook is engaged in the hook hole, the rotating roller can smoothly engage the hook with the hook to engage in the hook hole, thereby avoiding the phenomenon of half-engagement as much as possible. However, the roller-type auxiliary snap-fit mechanism also has some disadvantages: when the roller is set, a rotating shaft supporting the roller needs to be set, and the rotating shaft needs to have an independent supporting structure. However, the inner drum cover of the drum washing machine is usually a sheet metal part, and it is difficult and costly to construct a supporting structure on the sheet metal part; secondly, the shaft of the roller needs to be reliably fixed and cannot be detached at will, which increases the difficulty of the process; thirdly, the shaft of the roller and the roller cannot be tightly fitted, and a gap needs to be left to facilitate the rotation of the roller. In this way, the roller will vibrate during the operation of the drum, resulting in abnormal noise.

[0005] Accordingly, the art needs a new cover assembly to solve the above problems. Summary of the invention

[0006] To solve the above problems in the prior art, that is, to solve the problem that the inner lid of the existing top-opening drum washing machine is prone to a semi-fastened state, which affects the use safety, the first aspect of the present invention provides a lid assembly. The lid assembly includes a first lid and a second lid respectively pivotally connected to a base member. The first lid and the second lid are respectively provided with a hook and a hook hole at positions close to each other. The hook can be snapped into the hook hole along the pivoting direction to lock the first lid and the second lid. The lid assembly further includes an elastic member. The elastic member is disposed between the hook and the hook hole in a direction perpendicular to the pivoting direction. The elastic member includes a connecting portion and a deforming portion. The connecting portion is used to connect the elastic member to the hook. The deforming portion includes a first deforming portion. A protrusion is formed on the first deforming portion. And when observed in a direction perpendicular to the pivoting direction, the distance between the apex of the protrusion along its protruding direction and the hook is greater than the distance between the hook and the hook hole.

[0007] For the lid assembly provided by the present invention, by connecting an elastic member to the hook, the impact force generated by the rapid release of elastic potential energy when the elastic member restores deformation can be utilized to drive the hook to snap into the hook hole, thereby avoiding the semi-fastened state of the hook and the hook hole.

[0008] Specifically, by setting the deforming portion of the elastic member into a structure with a protrusion, when the elastic member starts to contact the side wall of the hook hole, the side wall of the hook hole squeezes the protrusion of the elastic member to press it down in the opposite direction of the protruding direction. When the user continuously applies pressure to the lid assembly, the elastic member will continuously deform and accumulate elastic potential energy. During this process, the moving speed of the hook in the hook hole slows down significantly compared to before. When the apex of the protrusion of the elastic member completely passes through the side wall of the hook hole, the elastic member breaks free from the restraint of the hook hole and rapidly restores deformation, causing the accumulated elastic potential energy to be quickly released. This process is equivalent to instantaneously increasing the closing force applied to the hook locally by several times, thereby prompting the hook to quickly snap into the hook hole, and effectively avoiding the phenomenon of the hook and the hook hole being semi-fastened. In addition, since the distance between the apex of the protrusion along its protruding direction and the hook is greater than the distance between the hook and the hook hole, while providing assistance to the hook, it can also limit the hook snapped into the hook hole to prevent the hook from coming out, so that the inner lids are stably locked together. In this way, when the drum assembly of the laundry treatment device is configured with this lid assembly, the use safety of the laundry treatment device can be improved.

[0009] It can be understood that those skilled in the art can set the specific structure of the elastic member according to the actual situation. In addition, there are various situations for the installation position of the elastic member on the hook. Moreover, there are also various connection methods between the elastic member and the hook.

[0010] For the above-mentioned cover assembly, in one possible implementation, the first deformation part is a strip-shaped structure, the connecting part includes a first connecting part and a second connecting part, and the first connecting part and the second connecting part are respectively connected to two ends of the strip-shaped structure.

[0011] By setting the first deformation part as a strip-shaped structure, it is beneficial for the elastic member to deform to accumulate elastic potential energy; in addition, by respectively arranging the first connecting part and the second connecting part at two ends of the strip-shaped structure, it is beneficial to realize the stable connection between the elastic member and the hook, and is beneficial to the uniform deformation of the elastic member.

[0012] It can be understood that the structural forms of the strip-shaped structure and the connecting parts at its two ends can be flexibly set according to the actual situation. For example, the cross-sectional shape of the strip-shaped structure can be circular, rectangular, square, trapezoidal, etc.; the structural shape of the first connecting part and the structural shape of the second connecting part can be the same or different, and the connection methods with the hook can be the same or different. For example, it can be a fixed connection, or a pivot connection, or one can be a fixed connection and the other can be a pivot connection.

[0013] For the above-mentioned cover assembly, in one possible implementation, the first connecting part and / or the second connecting part is a closed or unclosed ring-shaped structure.

[0014] In this way, a specific structural form of the first connecting part and / or the second connecting part is provided. Through such a setting, it is beneficial to the processing of the elastic member.

[0015] For the above-mentioned cover assembly, in one possible implementation, the ring-shaped structure is pivotally connected to the corresponding hook to assist the deformation of the first deformation part.

[0016] In this way, a connection method between the elastic member and the hook is provided. When the deformation part deforms, the protrusion of the deformation part will press down, and correspondingly, the two ends of the deformation part will extend outwards. By pivotally connecting the connecting part and the hook, without changing the position of the elastic member, the extension of the end part of the deformation part is absorbed by the rotation of the connecting part relative to the hook, thereby assisting in realizing the deformation of the deformation part.

[0017] For the above-mentioned cover assembly, in one possible implementation, the deformation part further includes two second deformation parts corresponding to the first connecting part and the second connecting part respectively, and the two second deformation parts are respectively arranged between the first deformation part and the first connecting part and between the first deformation part and the second connecting part. Wherein, when an external force is applied to the elastic member, the deformation direction of the second deformation part is opposite to that of the first deformation part.

[0018] In this way, another implementation of the deformable part is provided. Through such an arrangement, it is possible to absorb the extension of the end of the first deformable part by the deformation of the second deformable part, thereby jointly accumulating elastic potential energy. In addition, due to the provision of the second deformable part, the connection mode between the connecting part and the hook can be made more flexible. For example, the connecting part and the hook can be pivotally connected, or the connecting part and the hook can be fixedly connected.

[0019] In the preferred technical solution of the above-mentioned cover assembly, the annular structure is fixedly connected to the corresponding hook to assist the deformation of the second deformable part.

[0020] By such an arrangement, a connection mode between the elastic member and the hook is provided.

[0021] In the preferred technical solution of the above-mentioned cover assembly, all or part of the first deformable part, the second deformable part, and the connecting part are fixedly connected or integrally formed.

[0022] In the preferred technical solution of the above-mentioned cover assembly, a plurality of the hooks are arranged in a direction perpendicular to the pivoting direction, and / or

[0023] the number of the elastic members is greater than or equal to the number of the hooks.

[0024] By such an arrangement, various specific implementation manners of the elastic member are provided.

[0025] The second aspect of the present invention further provides a laundry treatment device, which is configured with the cover assembly in any one of the foregoing technical solutions.

[0026] Those skilled in the art can understand that since the laundry treatment device is configured with the cover assembly in the foregoing technical solution, it has all the technical effects of the foregoing cover assembly, which will not be elaborated herein.

[0027] In the preferred technical solution of the above-mentioned laundry treatment device, the laundry treatment device includes a cylinder, and the basic component is the cylinder.

[0028] By such an arrangement, a specific application scenario of the cover assembly is provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Next, with reference to Figures 1 - 10 the cover assembly of the present invention will be described in detail. Figure 1 is a schematic structural view of the cover assembly of the present invention in the locked state; Figure 2 is a schematic structural view of the first cover body of the present invention; Figure 3 is a schematic structural view of the second cover body of the present invention; Figure 4 is a top view of the cover assembly of the present invention in the locked state; Figure 5 is Figure 4 a sectional view taken along the A-A direction of Figure 6 is a schematic view of the cooperation between the hook and the hook hole plate of the present invention; Figure 7 is the first embodiment of the elastic member of the present invention; Figure 8 is the second embodiment of the elastic member of the present invention; Figure 9This is the third embodiment of the elastic member of the present invention; Figure 10 This is the fourth embodiment of the elastic member of the present invention.

[0047] The cover assembly provided by the embodiment of the present invention includes a first cover body and a second cover body that are respectively pivotally connected to the base member. The first cover body and the second cover body are respectively provided with a hook and a hook hole at positions close to each other. The hook can be snapped into the hook hole along the pivoting direction to lock the first cover body and the second cover body.

[0048] Specifically, the base member in this embodiment is the cylinder configured for a drum washing machine, specifically the cylinder of the inner drum. A hook 120 is provided on the first cover body 1, and a hook hole 210 is provided on the second cover body 2. Refer to Figure 1 and Figure 2 , the first cover body 1 includes a first body 11 and a first rotating shaft 10. The first body 11 is connected to the cylinder of the inner drum (not shown) through the first rotating shaft 10. The first body 11 is a sheet metal part. The first cover body 1 further includes a hook plate 12. Two hooks 120 are formed on the hook plate 12. In the installed state, the hook 120 is close to the front end of the first body 11. The hook plate 12 is fixedly connected to the first body 11 through a fastener.

[0049] It can be understood that the hook 120 can also be directly formed on the first body 11. The hook plate 12 is provided for convenient processing. In addition, the number of hooks 120 can be any number, and those skilled in the art can specifically configure according to actual needs.

[0050] Refer to Figure 1 and Figure 3 , the second cover body 2 includes a second body 21 and a second rotating shaft 20. The second body 21 is connected to the cylinder of the inner drum through the second rotating shaft 20. The second body 21 is a sheet metal part, and hook holes 210 corresponding to the number of hooks 120 are formed at its front end. Refer to Figure 4 and Figure 5 , in order to further enhance the strength of the sheet metal part at the hook hole 210, the second cover body 2 in this embodiment further includes a hook hole plate 22. The hook holes 210 on the hook hole plate 22 correspond to the hook holes 210 on the second body 21. In order to fix the hook hole plate 22, part of the edge of the hook hole 210 is extended and bent to form a flanging 211. As Figure 5 shown, the flangings 211 are respectively formed on two sides of the hook hole 210 along the direction perpendicular to the second rotating shaft 20. When closing the cover assembly, the hook 120 can be snapped into the hook hole 210 along the direction perpendicular to the pivoting direction to lock the first cover body 1 and the second cover body 2. The first cover body 1 and the second cover body 2 connected to the cylinder of the inner drum form a double-door structure and are connected with a linkage mechanism, so that the first cover body 1 and the second cover body 2 can be opened and closed synchronously.

[0051] Refer toFigure 4 and Figure 6 Moreover, the cover assembly in this embodiment further includes an elastic member 3. The elastic member 3 is disposed between the hook 120 and the hook hole 210 in a direction perpendicular to the pivoting direction, that is, in a direction parallel to the axial direction of the first rotating shaft 10 or the second rotating shaft 20. In this embodiment, one elastic member 3 is connected to each hook 120, and the two hooks 120 are connected with the elastic member 3 only on the side close to each other.

[0052] The elastic member 3 includes a connecting portion 30 and a deforming portion 31. The connecting portion 30 is used to connect the elastic member 3 to the hook 120, and the deforming portion 31 is used to accumulate and release elastic potential energy during operation.

[0053] In some feasible embodiments, the deforming portion 31 includes a first deforming portion 310 which is a strip structure. The connecting portion 30 includes a first connecting portion 300 and a second connecting portion 301. The first connecting portion 300 and the second connecting portion 301 are respectively connected to two ends of the strip structure. In some other feasible embodiments, the deforming portion 31 further includes two second deforming portions 311 corresponding to the first connecting portion 300 and the second connecting portion 301 respectively. The two second deforming portions 311 are respectively disposed between the first deforming portion 310 and the first connecting portion 300 and between the first deforming portion 310 and the second connecting portion 301. Wherein, when an external force is applied to the elastic member 3, the deformation direction of the second deforming portion 311 is opposite to that of the first deforming portion 310. Based on the above structure, the connection manner between the connecting portion 30 and the hook 120 can be a fixed connection, a pivoting connection, or a hinged connection, etc.

[0054] Specifically, Figure 7 shows a first embodiment of the elastic member 3. As Figure 7 shown, the deforming portion 31 of the elastic member 3 includes a first deforming portion 310 which is a strip structure and has a circular cross-section. An arc-shaped protrusion is formed on the first deforming portion 310. As Figure 6As shown, when observed along a direction perpendicular to the pivoting direction, the distance between the vertex of the protrusion along its protruding direction and the hook 120 is greater than the distance between the hook 120 and the hook hole 210. This is set so that during the process of the hook 120 being inserted into the hook hole 210, the side wall of the hook hole 210 can squeeze the protrusion to deform the deformed part 31 to accumulate sufficient elastic potential energy. In addition, the protrusion can also be in other structural forms, such as arc-shaped, sharp-cornered, etc. The connecting part 30 includes a first connecting part 300 and a second connecting part 301. The first connecting part 300 and the second connecting part 301 are respectively connected to both ends of the first deformed part 310. The first connecting part 300 and the second connecting part 301 have the same structure, both being an unclosed ring structure, and this kind of structure is easier to produce and process. In order for the first deformed part 310 to deform better and accumulate elastic potential energy, the first connecting part 300 and the second connecting part 301 can be pivotally connected to the hook 120 through rivets, bolts, etc.

[0055] Figure 8 Fig. shows the second embodiment of the elastic member 3. Different from Figure 7 that, Figure 8 the first connecting part 300 and the second connecting part 301 of the elastic member 3 in

[0056] Figure 9 are of a closed ring structure. By setting the first connecting part 300 and the second connecting part 301 as a closed ring structure, when it is pivotally connected to the hook 120, it can rotate better along the rotation axis to assist the deformation of the first deformed part 310, and at the same time, the connection with the hook 120 is also more stable. Figure 7 that, Figure 9 the deformed part 31 of the elastic member 3 in Figure 9 includes a first deformed part 310 and a second deformed part 311. In the case where an external force is applied to the elastic member 3, the deformation direction of the second deformed part 311 is opposite to that of the first deformed part 310. As shown in

[0057] Figure 10 Fig., the second deformed part 311 also forms a protrusion, and its protruding direction is opposite to that of the first deformed part 310. It can be understood that the protrusion of the second deformed part 311 can be arc-shaped, semi-circular, sharp-cornered, etc.

[0057] Figure 10 Fig. shows the fourth embodiment of the elastic member 3. Figure 10 The deformed part 31 of the elastic member 3 in Figure 9 is similar to that in Figure 9 and includes a first deformed part 310 and a second deformed part 311. Different from Figure 9 that, Figure 10 the cross-section of the elastic member 3 in Figure 9 is rectangular, for example, it can be processed from a steel sheet, while the elastic member 3 in Figure 9 can be formed by bending a steel wire.

[0058] As Figure 7 , Figure 9 and Figure 10 shown, the deformed part 31 and the connecting part 30 of the elastic member 3 are integrally formed; as Figure 8 shown, the deformed part 31 and the connecting part 30 are fixedly connected, such as by welding, bonding or other means. It can be understood that it can also be fixedly connected or integrally formed between all or part of the first deformed part 310, the second deformed part 311 and the connecting part.

[0059] Those skilled in the art can also understand that the number of the hooks 120 and the hook holes 210, and the number of the elastic members 3 can be configured as needed. In addition, the number of the elastic members 3 is greater than or equal to the number of the hooks 120. For example, the elastic members 3 can be arranged on both sides of one hook 120, or only on one side. One elastic member 3 or two elastic members 3 can be arranged on one side.

[0060] Next, in conjunction with Figure 6 and Figure 7 , the working principle of the cover assembly configured with the elastic member 3 will be described in detail. Specifically, the elastic member 3 is the structure in Figure 7 , in which the first connecting part 300 and the second connecting part 301 are pivotally connected to the hook 120, for example, by rivets. During the process of closing the cover, the user applies a cover-closing force to the second cover body 2, so that when the second cover body 2 rotates downward around the second rotating shaft 20, it drives the first cover body 1 to rotate downward around the first rotating shaft 10. The first cover body 1 is below and the second cover body 2 is above. When the second cover body 2 contacts the first cover body 1, the top edge of the hook 120 of the first cover body 1 first contacts the edge of the hook hole 210 of the second cover body 2. During the process of the hook 120 sliding in the hook hole 210, the side wall of the hook hole 210 and the inner side wall of the hook hole plate 22 sequentially move along the path of the first connecting part 300---the vertex of the protrusion. This process gradually squeezes the first deformed part 310, and the protrusion of the first deformed part 310 is pressed downward in the opposite direction of the protruding direction. At the same time, the first connecting part 300 and the second connecting part 301 rotate around their respective rotating shafts to assist the deformation of the first deformed part 310. When the vertex of the protrusion passes over the inner side wall of the hook hole plate 22 from bottom to top, the deformed part 31 that has accumulated a considerable amount of elastic potential energy will quickly recover its deformation. The direction of the force exerted by the quickly protruding first deformed part 310 on the edge of the inner side wall of the hook hole plate 22 is perpendicular to the first deformed part 310, and due to the rapid release of the elastic potential energy, the force exerted on the hook hole plate 22 is relatively large, which is equivalent to applying a force several times that of the cover-closing force to a local position on the hook hole plate 22, prompting the hook 120 to quickly slide in the hook hole 210 and finally making the hook plate 12 quickly and reliably stuck in the bend of the hook 120, realizing the locking of the first cover body 1 and the second cover body 2 and avoiding the phenomenon of semi-fastening.

[0061] The cover assembly provided by the present invention can drive the hook to snap into the hook hole by quickly releasing the impact force generated by the elastic potential energy when the elastic member resumes deformation by connecting the elastic member to the hook. Thus, the state of the hook being semi-fastened to the hook hole can be avoided. Specifically, by setting the deformed part of the elastic member into a structure with protrusions, when the elastic member starts to contact the side wall of the hook hole, the side wall of the hook hole squeezes the protrusions of the elastic member and presses it downward in the opposite direction of the protrusion direction. When the user continuously applies pressure to the cover assembly, the elastic member will continuously deform and accumulate elastic potential energy. During this process, the moving speed of the hook in the hook hole slows down significantly compared to before. When the apex of the protrusion of the elastic member completely passes through the side wall of the hook hole, the elastic member breaks free from the restraint of the hook hole and rapidly resumes deformation, causing the accumulated elastic potential energy to be quickly released. This process is equivalent to instantly increasing the closing force applied to the hook locally by several times, thereby prompting the hook to quickly snap into the hook hole, and effectively avoiding the phenomenon of the hook being semi-fastened to the hook hole. In addition, since the distance between the apex of the protrusion along its protruding direction and the hook is greater than the distance between the hook and the hook hole, while providing assistance to the hook, it can also limit the hook that has snapped into the hook hole to prevent the hook from coming out, so that the inner cylinder cover is stably locked together. In this way, when the cover assembly is configured for the drum assembly of the laundry treatment device, the use safety of the laundry treatment device can be improved.

[0062] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
