Description

Technical Field

[0001] The present invention relates to the technical field of laundry treatment, and more particularly to a door cover assembly for a washing machine and a laundry treatment device having the same. Background Art

[0002] In the related art, the door body of a conventional washing machine has a relatively large weight. When a user closes the door body, the door body will generate an impact force on the washing machine due to its own large weight. It is inevitable that noise will be generated when the door body collides with the washing machine during closing, resulting in poor user experience. Moreover, over time, both the washing machine and the door body will be damaged, and the service life of the washing machine will also be reduced.

[0003] Currently, the method for solving the problem of the impact caused by the closing of the door body on the washing machine is to provide a damping member on the door body part of the washing machine. The damping member provides resistance to the falling door body to dissipate the impact force generated by the door body due to its own weight. This method can reduce the noise generated when the door body is closed while enhancing the feel of using the door body.

[0004] In the prior art, the fixing structure of a damping door cover of a washing machine designs a relatively small damping door cover structure. However, this damping structure is complex to assemble and disassemble, time-consuming and laborious. Moreover, this damping structure is exposed and easily rusted. After rusting, the difficulty of disassembly and assembly will increase, and it is very easy to be damaged and cause the loss of function.

[0037] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "mounted", "connected", "connected", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection or may communicate with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two elements or the interaction relationship between two elements.

[0040] In the related art, the door body of a conventional washing machine has a relatively large weight. When a user closes the door body, due to its large own weight, the door body will generate an impact force on the washing machine. When the door body collides with the washing machine during closing, noise is inevitably generated, resulting in poor user experience. Moreover, over time, both the washing machine and the door body will be damaged, and the service life of the washing machine will also be reduced.

[0041] Currently, the method for solving the problem of the impact caused by the closing of the door body on the washing machine is to provide a damping member in the door body part of the washing machine. The damping member is used to provide resistance to the falling door body to dissipate the impact force generated by the door body due to its own weight. This method can reduce the noise generated when the door body is closed and enhance the feel of using the door body at the same time.

[0042] In the prior art, the fixed structure of a damping door cover of a washing machine designs a relatively small damping door cover structure. However, this damping structure is complex to assemble and disassemble, time-consuming and laborious. Moreover, this damping structure is exposed outside and is easily rusted. After rusting, the difficulty of disassembly and assembly will increase, and it is very easy to be damaged and cause the loss of function. Therefore, designing a damping structure with a simple and easy-to-dismantle structure is the problem to be solved in this application.

[0043] The following refers to Figures 1-4 Describe the door cover assembly 1 for a washing machine according to an embodiment of the present invention.

[0044] As Figure 1 shown, the door cover assembly 1 according to the present invention includes: a workbench 10, a rotating shaft fixing part 20, a rotating shaft 30, and a cover plate 40. The workbench 10 is adapted to be connected to the washing machine, and the laundry treatment operation can be performed through the workbench 10 when treating laundry; the cover plate 40 is adapted to shield the workbench 10; the rotating shaft 30 can connect the workbench 10 and the cover plate 40; the rotating shaft fixing part 20 is adapted to cooperate with the rotating shaft 30 to connect the workbench 10 and the cover plate 40.

[0045] A rotating shaft support portion 11 is provided on the workbench 10. An axially outwardly open rotating shaft installation space 11a is provided within the rotating shaft support portion 11. The rotating shaft installation space 11a is adapted to receive and support the rotating shaft 30. The rotating shaft fixing portion 20 is fixedly connected to the workbench 10 and forms a rotating shaft installation position, and at least a part of the rotating shaft installation position is received within the rotating shaft installation space 11a. Specifically, at least a part of the rotating shaft installation position can contact the rotating shaft 30 to limit and fix the rotating shaft 30 within the rotating shaft installation space 11a. The rotating shaft 30 is supported by the rotating shaft installation position, and at least a part of the rotating shaft 30 is received within the rotating shaft installation space 11a, and at least a part of the rotating shaft 30 extends out of the rotating shaft support portion 11. The cover plate 40 is connected to the rotating shaft 30. Specifically, the part of the rotating shaft 30 received within the rotating shaft installation space 11a can contact the rotating shaft installation position, and this part of the rotating shaft 30 can fix the rotating shaft 30 within the rotating shaft installation space 11a; the part of the rotating shaft 30 extending out of the rotating shaft support portion 11, that is, the part extending out of the rotating shaft installation space 11a, can connect the workbench 10 having the rotating shaft support portion 11 to the cover plate 40. One part of the rotating shaft 30 is provided within the workbench 10, and the other part is connected to the cover plate 40.

[0046] In some embodiments of the present invention, as Figures 1-3 shown, the rotating shaft 30 includes a damping structure. The rotating shaft 30 is provided within the rotating shaft installation space 11a, and a part of the rotating shaft 30 extends out of the rotating shaft installation space 11a and out of the rotating shaft support portion 11. The part extending out of the rotating shaft support portion 11 is connected to the cover plate 40. The rotating shaft 30 connects the workbench 10 to the cover plate 40; the part of the rotating shaft fixing portion 20 received within the rotating shaft installation space 11a contacts the rotating shaft 30, limiting the position of the rotating shaft 30 within the rotating shaft installation space 11a and preventing the rotating shaft 30 from slipping off, making the connection between the workbench 10 and the cover plate 40 more secure. At the same time, the rotating shaft installation space 11a can be used to protect the rotating shaft 30, extend the service life of the rotating shaft 30, and also change the overall assembly sequence of the door cover assembly 1, reducing the installation difficulty of the door cover assembly 1.

[0047] The door cover assembly 1 is provided on the laundry treatment device. The workbench 10 in the door cover assembly 1 cooperates with the laundry treatment device. The cover plate 40 and the workbench 10 are connected by the rotating shaft 30. Therefore, the cover plate 40 can rotate open and close with the position where the rotating shaft 30 is located as the center of rotation. When the cover plate 40 in the door cover assembly 1 is opened, the cover plate 40 can be smoothly opened under the action of the rotating shaft 30; when the cover plate 40 is closed, the cover plate 40 can be smoothly closed under the action of the rotating shaft 30.

[0048] In the door cover assembly 1 related to the present invention, a rotating shaft support portion 11 and a rotating shaft fixing portion 20 cooperating with the rotating shaft support portion 11 are provided on the workbench 10. A rotating shaft installation space 11a is formed within the rotating shaft support portion 11. The rotating shaft 30 can be pre-installed within the rotating shaft installation space 11a. The rotating shaft 30 connects the workbench 10 and the cover plate 40. When the cover plate 40 is opened to perform clothing processing operations through the workbench 10, the rotating shaft fixing portion 20 is fixed to the workbench 10, and at least a part of the rotating shaft fixing portion 20 is further received within the rotating shaft installation space 11a to maintain the relative connection stability between the rotating shaft 30 and the rotating shaft support portion 11. The door cover assembly 1 is convenient to disassemble and assemble. The rotating shaft 30 is located within the rotating shaft installation space 11a and is not easily rusted, with high reliability.

[0049] According to some embodiments of the present invention, as Figure 1 , Figure 4 shown, a support groove 20a is formed on the rotating shaft fixing portion 20. The support groove 20a faces the rotating shaft support portion 11. The support groove 20a can be configured as an arc-shaped groove for restricting the position of the rotating shaft 30. When the rotating shaft 30 is disposed in the support groove 20a, the rotating shaft 30 can maintain abutment with the inner peripheral wall of the support groove 20a to ensure the stability of the rotation of the rotating shaft 30.

[0050] Specifically, when assembling the door cover assembly 1 of the present application, the rotating shaft 30 can be first placed into the rotating shaft installation space 11a. At least a part of the rotating shaft 30 extends out of the rotating shaft support portion 11 and is connected to the cover plate 40 in a matching manner. The open end of the support groove 20a provided in the rotating shaft fixing portion 20 faces the rotating shaft installation space 11a. After the rotating shaft 30 is disposed in the rotating shaft installation space 11a, the rotating shaft fixing portion 20 is matched with the rotating shaft support portion 11 so that the support groove 20a provided in the rotating shaft fixing portion 20 is matched with the rotating shaft 30, and the rotating shaft installation space 11a is closed to realize the fixation of the rotating shaft 30. At the same time, it can prevent water flow and the like from entering the rotating shaft installation space 11a, and can protect the rotating shaft 30 from rusting when encountering water. The door cover assembly 1 is simple to disassemble and assemble, with high assembly efficiency. The user can accurately and efficiently assemble the door cover assembly 1, improving the user experience.

[0051] According to some embodiments of the present invention, as Figures 1-3 shown, the rotating shaft 30 includes a pivot shaft 31 and a damping shaft 32. The pivot shaft 31 and the damping shaft 32 are arranged within the support groove 20a. The pivot shaft 31 and the damping shaft 32 extend in directions away from each other, and the pivot shaft 31 and the damping shaft 32 are respectively connected to the cover plate 40.

[0052] Specifically, as Figure 3As shown, the rotating shaft 30 is divided into two parts. One part is the pivot shaft 31, and the other part is the damping rotating shaft 32. The damping rotating shaft 32 can provide resistance for the cover plate 40 during the closing process to prevent the cover plate 40 from colliding with the workbench 10, effectively avoiding damage and noise generation when the cover plate 40 collides with the workbench 10. The pivot shaft 31 and the damping shaft are symmetrically arranged to maintain the stability of the cover plate 40 during the flipping process.

[0053] According to some embodiments of the present invention, as Figure 4 shown, a limiting groove 20b is provided on the inner wall of the support groove 20a. As Figures 1-3 shown, the damping rotating shaft 32 is provided with a limiting protrusion 32a that cooperates with the limiting groove 20b. Through the cooperation of the limiting groove 20b and the limiting protrusion 32a, the support groove 20a can limit the rotation of the damping rotating shaft 32. One end of the damping rotating shaft 32 is located in the support groove 20a and is fixed to the rotating shaft support portion 11 by using the limiting groove 20b. The other end of the damping rotating shaft 32 extends out of the rotating shaft installation space 11a and is connected to the cover plate 40. The two ends of the damping rotating shaft 32 can rotate relative to each other and need to overcome a certain torque to achieve the damping feeling when the cover plate 40 rotates. One end of the damping rotating shaft 32 is fixed by using the limiting groove 20b to maintain the damping rotation of the cover plate 40 relative to the workbench 10.

[0054] According to some embodiments of the present invention, as Figure 1 shown, the cover plate 40 is formed with a first support foot 41 and a second support foot 42. The first support foot 41 and the second support foot 42 are respectively formed with a first fitting hole 41a and a second fitting hole 42a. The first fitting hole 41a cooperates with the damping rotating shaft 32, and the first fitting hole 41a is configured as a non-circular hole. The second fitting hole 42a cooperates with the pivot shaft 31.

[0055] Specifically, as Figure 1 shown, the first support foot 41 and the second support foot 42 are provided on the same side of the cover plate 40. When the cover plate 40 cooperates with the workbench 10, the rotating shaft support portion 11 is located between the first support foot 41 and the second support foot 42. The rotating shaft support portion 11 extends in the length direction and has a first limiting hole 11b and a second limiting hole 11c at both ends respectively. One end of the damping rotating shaft 32 extends out of the rotating shaft installation space 11a and cooperates with the first limiting hole 11b. The cross-section of one end of the damping rotating shaft 32 is configured as a non-circular cross-section so that the damping rotating shaft 32 and the first limiting hole 11b are in a flat position fit to prevent one end of the damping rotating shaft 32 from rotating relative to the first limiting hole 11b.

[0056] According to some embodiments of the present invention, as Figure 1 、 Figure 4As shown, a stop portion 21 protruding toward the rotation shaft installation space 11a is provided in the support groove 20a, and one side of the pivot shaft 31 and the damping rotation shaft 32 facing each other abuts against the stop portion 21 respectively. To prevent the damping rotation shaft 32 and the pivot shaft 31 from axially moving, and to maintain the stability of the cover plate 40 assembly after installation, both sides of the stop portion 21 abut against the damping rotation shaft 32 and the side of the pivot shaft 31 facing each other respectively, so as to limit the axial movement of the damping rotation shaft 32 and the pivot shaft 31. At the same time, the stop portion 21 can keep the movements of the pivot shaft 31 and the damping rotation shaft 32 relatively independent to prevent the movements of the two from interfering with each other. The pivot shaft 31 and the damping rotation shaft 32 are two independent parts of the rotation shaft 30, and there is a spacing between them. The stop portion 21 is arranged in this spacing. The stop portion 21 can abut against the pivot shaft 31 and the damping rotation shaft 32 at the same time to completely clamp them in the limit space, preventing the pivot shaft 31 and the damping rotation shaft 32 from axially moving in the length direction and interfering with the opening and closing of the cover plate 40.

[0057] According to some embodiments of the present invention, as Figure 1 shown, a first wire harness channel 20c is formed in the rotation shaft fixing portion 20. As Figure 3 shown, a second wire harness channel 31a communicating with the first wire harness channel 20c is formed in the pivot shaft 31. Specifically, a display board is provided on the workbench 10, and the display board is suitable for a user to perform command operations on the clothing treatment device. There is a power supply assembly in the clothing treatment device, and the display board works by connecting to the power supply assembly through a wire harness. The wire harness extends from the power supply assembly to the workbench 10. The wire harness extends into the rotation shaft fixing portion 20 through the first wire harness channel 20c of the rotation shaft fixing portion 20. At least part of the first wire harness channel 20c is formed inside the stop portion 21. The outlet of the first wire harness channel 20c is located on the end face where the stop portion 21 abuts against one end of the pivot shaft 31. The pivot shaft 31 is provided with a second wire harness channel 31a and the second wire harness channel 31a communicates with the first wire harness channel 20c at the said one end of the pivot shaft 31. The wire harness is thus connected to the display board on the workbench 10. The setting of the first wire harness channel 20c and the second wire harness channel 31a can make full use of the internal space of the door cover assembly 1, and minimize the proportion of the space required for the connecting wire harness in the total space of the door cover assembly 1.

[0058] More specifically, a through hole penetrating in the length direction of the pivot shaft 31 is provided inside the pivot shaft 31, and this through hole is the second wire harness channel 31a.

[0059] According to some embodiments of the present invention, as Figure 1 、 Figure 4 shown, the rotation shaft fixing portion 20 forms a connecting platform 22. The connecting platform 22 and the workbench 10 are fixedly connected by a fastener 50. The rotation shaft fixing portion 20 is provided with the connecting platform 22, which can stably connect the rotation shaft fixing portion 20 and the workbench 10. The rotation shaft fixing portion 20 fixed on the workbench 10 makes the fixing of the rotation shaft 30 more reliable.

[0060] Specifically, as Figure 1 shown, a support groove 20a is formed on one side of the rotating shaft fixing part 20, and a stop part 21 is formed on the inner wall of the support groove 20a; the rotating shaft fixing part 20 is fitted with the rotating shaft support part 11, and a connecting platform 22 is formed on the side of the rotating shaft fixing part 20 close to the workbench 10, and the connecting platform 22 extends away from the side of the rotating shaft fixing part 20 close to the workbench 10; a through hole is formed at the connecting platform 22, and an installation hole is also provided at the corresponding position of the workbench 10. The fastener 50 is fitted with the installation hole of the workbench 10 through the through hole of the connecting platform 22, and the fastener 50 fixedly connects the rotating shaft fixing part 20 and the workbench 10.

[0061] In some embodiments of the present invention, there are two through holes in the connecting platform 22, two installation holes in the workbench 10, and two fasteners 50.

[0062] In some embodiments of the present invention, the fastener 50 is a screw, and the screw passes through the through hole provided on the connecting platform 22 and is fitted with the threaded hole provided on the workbench 10 to fix the rotating shaft fixing part 20.

[0063] According to some embodiments of the present invention, a first wire harness channel 20c is provided in the connecting platform 22. The wire harness extends along the first wire harness channel 20c, the wire harness extends from the connecting platform 22 to the stop part 21, and enters the pivot shaft 31 from the stop part 21, and the wire harness extends along the second wire harness channel 31a in the pivot shaft 31.

[0064] In some embodiments of the present invention, as Figures 1-4 shown, the door cover assembly 1 includes a workbench 10, a cover plate 40, a rotating shaft 30, a rotating shaft fixing part 20, and a fastener 50. A rotating shaft support part 11 is provided on the workbench 10, and a rotating shaft installation space 11a that is open to the outside is provided in the rotating shaft support part 11. The rotating shaft support part 11 extends in the length direction, and has a first limit hole 11b and a second limit hole 11c at both ends respectively. The rotating shaft 30 is divided into two parts, one part is a pivot shaft 31, and the other part is a damping rotating shaft 32. One end of each of the pivot shaft 31 and the damping rotating shaft 32 is arranged in the rotating shaft support part 11, and the other ends of the pivot shaft 31 and the damping rotating shaft 32 both extend out of the rotating shaft support part 11. A first support foot part 41 that cooperates with the damping rotating shaft 32 and a second support foot part 42 that cooperates with the pivot shaft 31 are formed on the cover plate 40, and a first cooperation hole 41a and a second cooperation hole 42a that facilitate the other ends of the pivot shaft 31 and the damping rotating shaft 32 to extend out and be snap-fitted are respectively formed on the first support foot part 41 and the second support foot part 42. The rotating shaft fixing part 20 is fixedly connected to the workbench 10 and forms a rotating shaft installation position. A support groove 20a is formed on one side of the rotating shaft fixing part 20, a stop part 21 is formed on the inner wall of the support groove 20a, a connecting platform 22 is formed on the side of the rotating shaft fixing part 20 close to the workbench 10, and a through hole is formed at the connecting platform 22.

[0065] When installing the door cover assembly 1, first place the rotating shaft support portion 11 of the workbench 10 between the first foot portion 41 and the second foot portion 42 of the cover plate 40, and align the first limiting hole 11b and the second limiting hole 11c with the first mating hole 41a and the second mating hole 42a. Secondly, place the pivot shaft 31 into the rotating shaft installation space 11a and pass it through the second limiting hole 11c and the second mating hole 42a, then place the damping rotating shaft 32 into the rotating shaft installation space 11a and pass it through the first limiting hole 11b and the second limiting hole 11c, thereby initially fixing the cover plate 40 and the workbench 10. Then, extend the wire harness of the display board from the end of the pivot shaft 31 extending out of the rotating shaft support portion 11 into the second wire harness channel 31a.
