Description

Technical Field

[0001] This application relates to the field of sealing technology for top-loading drum washing machines, and more particularly to a top-loading drum washing machine. Background Technology

[0002] Top-loading front-loading washing machines, also known as top-loading drum washing machines, differ from common front-loading drum washing machines. The lid of a top-loading drum washing machine is located on top of the machine body, allowing users to add and remove clothes from the top. This design combines the convenient loading method of traditional top-loading top-loading washing machines with the water-saving and gentle washing advantages of front-loading washing machines.

[0003] Because the axis of the drum in a top-loading drum washing machine is perpendicular to the height of the machine, and the opening of the top-loading drum washing machine is located on the periphery of the drum, the centrifugal force of the drum easily throws the cleaning water onto the lid when washing clothes, and then seeps out from the gap between the lid and the machine body components. Summary of the Invention

[0004] This application provides a top-loading drum washing machine, which can form a larger sealing surface between the lid assembly and the body assembly, thereby improving the sealing performance between the lid assembly and the body assembly, and ensuring the sealing performance between the lid assembly and the body assembly even after the lid assembly is deformed.

[0005] The top-loading drum washing machine includes a body assembly and a lid assembly. The top wall of the body assembly has an opening, and a door seal is provided around the opening. The lid assembly includes a lid and a first sealing element. The lid is hinged to the body assembly. The lid has a first receiving groove. When the lid is in the closed position, the first receiving groove is located on the side of the lid facing the body assembly. The first sealing element is partially located in the first receiving groove. When the lid is in the closed position, the first sealing element contacts the end face of the door seal.

[0006] In the top-loading drum washing machine based on the embodiments of this application, when the lid assembly is in the closed position, the lid closes the opening. Since the first seal is partially inside the first receiving groove and partially outside the first receiving groove, the structure of the first seal outside the first receiving groove will be squeezed against the body assembly, so that the first seal and the body assembly have a larger sealing surface.

[0007] In addition, after prolonged use of the top-loading drum washing machine, the lid may deform. Since the sealing surface is formed by the mutual compression between the first sealing element and the body assembly, even if the lid deforms to a certain extent, as long as the lid assembly is in the closed position, the first sealing element and the body assembly can compress each other to form a sealing surface. This ensures that the top-loading drum washing machine can still maintain the sealing between the lid and the body assembly after the lid deforms.

[0008] In some embodiments of this application, the first seal includes a connecting portion and a first sealing portion, the connecting portion being installed within the first receiving groove; the first sealing portion is at least partially located outside the first receiving groove, the first sealing portion having a fixed end and a free end disposed opposite to each other, the fixed end being connected to the connecting portion, and when the cover is in the open state, the direction from the fixed end to the free end is set at an angle to the thickness direction of the cover; wherein, when the cover is in the closed position, the first sealing portion and the door seal are pressed against each other to bend the first sealing portion, and the free end moves radially along the opening, thereby forming a sealing surface between the first sealing portion and the door seal.

[0009] Based on the above embodiments, the connecting part realizes the connection between the first sealing element and the cover. The direction from the fixed end to the free end of the first sealing part forms an angle with the thickness direction of the cover, that is, the extension direction of the first sealing element forms an angle with the thickness direction of the cover. After the first sealing element and the body assembly are pressed against each other, the first sealing part can be bent at any position between the free end and the fixed end. During this process, the free end moves radially along the opening to form a sealing surface between the first sealing part and the body assembly, thereby realizing the sealing of the cover assembly and the body assembly.

[0010] In some embodiments of this application, when the cover is in the open state, the distance between the free end of the first sealing part and the fixed end of the first sealing part along the thickness direction of the cover is L, 5mm≤L≤1mm; when the cover is in the closed position, the distance between the fixed end of the first sealing part and the side of the body assembly with the opening is M, 1mm≤M≤3mm.

[0011] Based on the above embodiments, the minimum value of L is greater than the maximum value of M, ensuring that when the cover is in the closed position, the first sealing part and the body assembly can be squeezed together to form a sealing surface.

[0012] In some embodiments of this application, the thickness of the first sealing portion gradually decreases from the fixed end to the free end.

[0013] Based on the above embodiments, it can be understood that when the first sealing part and the body assembly are pressed against each other, the free end of the first sealing part contacts the body assembly first. As the cover gradually rotates towards the closed position, the first sealing part gradually bends and deforms from the free end until the fixed end. Therefore, the deformation of the free end is the largest and the deformation of the fixed end is the smallest. The thickness of the first sealing part gradually decreases from the fixed end to the free end, that is, the thickness of the free end is the thinnest and the thickness of the fixed end is the thickest. This is beneficial for the first sealing part to deform from the free end and for the deformation to gradually decrease.

[0014] In some embodiments of this application, when the cover is in the open state, the angle between the direction from the fixed end to the free end and the thickness direction of the cover is α, where 20°≤α≤80°.

[0015] Based on the above embodiments, after the first sealing part contacts the body assembly, the body assembly guides the free end of the first sealing part, and the free end of the first sealing part will move radially along the opening. Within this range, the body assembly has a good guiding effect on the first sealing part.

[0016] In some embodiments of this application, the first seal further includes a second sealing portion, which protrudes from the surface of the connecting portion and abuts against the groove wall of the first receiving groove.

[0017] Based on the above embodiments, the second sealing part seals the gap between the connecting part and the wall of the first receiving groove after pressing against the groove wall of the first receiving groove, thereby reducing the amount of liquid leakage from the body assembly through the gap between the connecting part and the first receiving groove.

[0018] In some embodiments of this application, the cover includes a cover plate, an annular base plate, a first annular wing plate, and a second annular wing plate. The first annular wing plate is fixed to the inner side of the base plate, and the second annular wing plate is fixed to the outer side of the base plate, so that the annular base plate, the first annular wing plate, and the second annular wing plate form the first receiving groove. The cover plate is connected to the first annular wing plate and / or the annular base plate.

[0019] Based on the above embodiments, the cover is composed of a cover plate and an annular bottom plate, a first annular wing plate and a second annular wing plate that form a first receiving groove. The cover plate is the main structure of the cover and is used to cover the opening. The annular bottom plate, the first annular wing plate and the second annular wing plate form a first receiving groove to connect the first sealing element.

[0020] In some embodiments of this application, the hood assembly further includes a fastener, which is at least partially located within the first receiving groove and is fixedly connected to the annular base plate, the first annular wing plate, or the second annular wing plate.

[0021] Based on the above embodiments, the first sealing member is fixed in the first receiving groove by a fastener. After the fastener is connected to the annular bottom plate, the first annular wing plate or the second annular wing plate, the fastener is connected to the cover, thereby fixing the first sealing member to the cover and allowing the first sealing member to rotate with the cover plate relative to the machine body assembly.

[0022] In some embodiments of this application, both the door seal and the first sealing element are made of elastic material.

[0023] Based on the above embodiments, when the door seal and the first sealing element are pressed against each other, both the door seal and the first sealing element can deform, so that a sealing surface is formed between the door seal and the first sealing element.

[0024] In some embodiments of this application, the machine body assembly includes a machine body and a worktable. The worktable is fixed to the top of the machine body, and the top wall of the worktable has a second receiving groove. The door seal is sealed to the worktable and is partially located in the second receiving groove to abut against the first sealing member.

[0025] Based on the above embodiments, the portion of the door seal located in the second receiving groove is used to contact the first sealing part, thereby achieving a seal between the cover assembly and the body assembly when the cover assembly is in the closed position. Furthermore, the door seal is sealed to the worktable, thus achieving a sealed connection between the door seal and the body assembly. In this way, the door seal achieves a sealed connection with both the body assembly and the cover assembly.

[0026] In some embodiments of this application, the workbench includes a first main body and a second main body, the first main body having a second receiving groove, the second main body being disposed around the periphery of the first main body, and a sealing gap between the two; the door seal includes a first sealing section, a second sealing section and a third sealing section connected in sequence, the first sealing section being located in the first sealing groove, the second sealing section being located in the sealing gap, and the third sealing section being connected to the machine body.

[0027] Based on the above embodiments, the workbench includes a first main body and a second main body. The first main body has a second receiving groove. A sealing gap for accommodating a door seal structure is formed between the first main body and the second main body. The second sealing section of the door seal is located within the sealing gap to achieve a sealed connection between the door seal and the workbench. The first sealing section of the door seal is located within the second receiving groove. When the cover assembly is in the closed position, the cover assembly and the body assembly are in a sealed state. The third sealing section of the door seal is connected to the body to achieve a sealed connection between the door seal and the body. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0036] Top-loading front-loading washing machines, also known as top-loading drum washing machines, differ from common front-loading drum washing machines. The lid of a top-loading drum washing machine is located on top of the machine body, allowing users to add and remove clothes from the top. This design combines the convenient loading method of traditional top-loading top-loading washing machines with the water-saving and gentle washing advantages of front-loading washing machines.

[0037] Because the axis of the drum in a top-loading drum washing machine is perpendicular to the height of the machine, and the opening of the top-loading drum washing machine is located on the periphery of the drum, the centrifugal force of the drum easily throws the cleaning water onto the lid when washing clothes, and then seeps out from the gap between the lid and the machine body components.

[0038] To solve the above technical problems, please refer to Figures 1 to 3 As shown in the figure, this application discloses a top-loading drum washing machine. The top-loading drum washing machine includes a body assembly 10 and a lid assembly 20. The top wall of the body assembly 10 has an opening 1311, and a door seal 12 is provided around the opening 1311. The lid assembly 20 includes a lid 21 and a first sealing member 22. The lid 21 is hinged to the body assembly 10. The lid 21 has a first receiving groove 215. When the lid 21 is in the closed position, the first receiving groove 215 is located on the side of the lid 21 facing the body assembly. The first sealing member 22 is partially located in the first receiving groove 215. When the lid 21 is in the closed position, the first sealing member 22 is in contact with the end face of the door seal 12.

[0039] In the embodiments of this application, the absence of contact between the first sealing part 222 and the body assembly 10 refers to the case where the cover 21 is in the open state; the case where the cover 21 is in the closed position refers to the case where the first sealing part 222 is in contact with the body assembly 10, and the case where the cover 21 is in the position when the first sealing part 222 can no longer deform when the cover 21 is not subjected to external force.

[0040] The machine body assembly 10 is equipped with a roller for holding the items to be washed and the washing water. The opening 1311 is used by the user to put the items to be washed into the machine body assembly 10. The cover assembly 20 is used to close the opening 1311 of the machine body assembly 10 when the machine body assembly 10 is cleaning the items to be washed.

[0041] It is understood that the cover assembly 20 has a closed position and a maximum open position. The cover assembly 20 can rotate relative to the body assembly 10 between the closed position and the maximum open position. The closed position refers to the position of the cover assembly 20 relative to the body assembly 10 when the cover assembly 20 closes the opening 1311 of the body assembly 10. The maximum open position refers to the position of the cover assembly 20 relative to the body assembly 10 after rotating to the maximum angle relative to the body assembly 10 from the closed position.

[0042] In the top-loading drum washing machine based on the embodiments of this application, when the lid assembly 20 is in the closed position, the lid 21 closes the opening 1311. Since the first seal 22 is partially inside the first receiving groove 215 and partially outside the first receiving groove 215, the structure of the first seal 22 outside the first receiving groove 215 will be squeezed against the body assembly 10, so that the first seal 22 and the body assembly 10 have a larger sealing surface.

[0043] In addition, after the top-loading drum washing machine has been used for a long time and the lid 21 has deformed, since the sealing surface is formed between the first sealing element 22 and the body assembly 10 after the first sealing element 22 is squeezed against each other, even if the lid 21 has deformed to a certain extent, as long as the lid assembly 20 is in the closed position, the first sealing part 222 and the body assembly 10 can squeeze against each other to form a sealing surface, so that the top-loading drum washing machine can still ensure the sealing between the lid 21 and the body assembly 10 after the lid 21 is deformed.

[0044] Please refer to Figures 1 to 3 As shown, in some embodiments of this application, the first seal 22 includes a connecting portion 221 and a first sealing portion 222. The connecting portion 221 is installed in the first receiving groove 215. The first sealing portion 222 is at least partially outside the first receiving groove 215. The first sealing portion 222 has a fixed end and a free end that are disposed opposite to each other. The fixed end is connected to the connecting portion 221. When the cover 21 is in the open state, the direction from the fixed end to the free end is set at an angle to the thickness direction of the cover 21. When the cover 21 is in the closed position, the first sealing portion 222 and the door seal 12 are pressed against each other to bend the first sealing portion 222 and to move the free end radially along the opening 1311, thereby forming a sealing surface between the first sealing portion 222 and the door seal 12.

[0045] In the embodiments of this application, the fixed end refers to one end of an object that is fixed and cannot move or rotate in any direction; the free end refers to one end of an object that is not subject to fixed constraints or restrictions and is allowed to move or change freely within a certain range.

[0046] It is understood that when the cover 21 is in the closed position, at least the first sealing portion 222 of the first seal 22 surrounds the periphery of the opening 1311, that is, at least the first sealing portion 222 is configured as an annular structure. In some embodiments of this application, both the connecting portion 221 and the first sealing portion 222 are configured as annular structures.

[0047] When the cover 21 is in the closed position, it closes the opening 1311. At this time, the first sealing part 222 and the body assembly 10 are pressed against each other. Since the direction 'a' from the fixed end to the free end forms an angle with the depth direction of the body assembly 10, that is, the extension direction of the first sealing part 222 forms an angle with the depth direction of the body assembly 10, after the first sealing part 222 and the body assembly 10 are pressed against each other, the first sealing part 222 can be bent at any position between the free end and the fixed end, and the free end is radially along the opening 1311. The first sealing part 222 moves (moving towards the center of the opening 1311 or towards the edge of the opening 1311). The elastic potential energy generated after the first sealing part 222 deforms makes the first sealing part 222 fit tightly against the body assembly 10. Even if the plane where the body assembly 10 and the first sealing part 222 meet is not flat, the first sealing part 222 can still form a sealing surface with the body assembly 10 under the elastic action of the first sealing part 222. Moreover, the sealing surface has a larger area, which ensures the sealing between the cover 21 and the body assembly 10.

[0048] Furthermore, even after prolonged use of the top-loading drum washing machine causes deformation of the lid 21, the sealing surface is formed between the first sealing part 222 and the body assembly 10 after being pressed together and bent at any position between the free end and the fixed end. Therefore, even if the lid 21 deforms, as long as the lid 21 is in the closed position, the first sealing part 222 and the body assembly 10 can still press together to form a sealing surface. This ensures that the top-loading drum washing machine maintains a tight seal between the lid 21 and the body assembly 10 even after deformation. Moreover, it eliminates the need to increase the closing pressure of the top-loading drum washing machine, ensuring a good user experience when opening and closing the lid 21.

[0049] In some embodiments of this application, when the cover 21 is in the open state, the distance from the free end of the first sealing part 222 to the fixed end of the first sealing part 222 along the thickness direction of the cover 21 is L, 5mm≤L≤10mm, for example, L is 6mm, 7mm, 8mm or 9mm, etc.; when the cover 21 is in the closed position, the distance from the fixed end of the first sealing part 222 to the side of the body assembly 10 with the opening 1311 is M, 1mm≤M≤3mm; for example, 1.5mm, 2.0mm or 2.5mm, etc.

[0050] The minimum value of L is greater than the maximum value of M, ensuring that the first sealing part 222 and the body assembly 10 can be squeezed together to form a sealing surface when the cover 21 is in the closed position. In combination with the above-mentioned configuration of the first sealing part 222 as a ring structure, it can be known that the first sealing ring is a ring surface. From the above-mentioned range of values ​​of L and M, it can be known that the ring width of the sealing surface formed between the first sealing part 222 and the body assembly 10 is at least 2mm and at most 9mm.

[0051] It is understandable that if L is too long, the elastic potential energy generated by the first sealing part 222 after bending will be too small, resulting in a reduction in the sealing effect between the first sealing part 222 and the body assembly 10. In a specific embodiment of this application, L is 7mm. At this time, the first sealing part 222 can generate sufficient elastic potential energy after deformation to ensure that the first sealing part 222 and the body assembly 10 can fit tightly together after being squeezed together.

[0052] Similarly, if M is too large, the first sealing part 222 will have a longer distance in the depth direction of the body assembly 10 to be squeezed against the body assembly 10 to form the seal. However, if M is too small, the first sealing part 222 will need to be bent at a large angle during the deformation process. In a specific embodiment of this application, M is 2mm. At this time, the first sealing part 222 only needs to be bent at a suitable angle during the deformation process, and only part of the first sealing part 222 is bent. Combined with L being 7mm, a sealing ring with a width of 5mm is formed between the first sealing part 222 and the body assembly 10.

[0053] Please refer to Figure 4 as well as Figure 5 As shown, in some embodiments of this application, the thickness of the first sealing part 222 gradually decreases from the fixed end to the free end. It can be understood that when the first sealing part 222 and the body assembly 10 are pressed against each other, the free end of the first sealing part 222 contacts the body assembly 10 first. As the cover 21 gradually rotates towards the closed position, the first sealing part 222 gradually bends and deforms from the free end. It can be seen that the deformation at the free end is the largest and the deformation at the fixed end is the smallest. The thickness of the first sealing part 222 gradually decreases from the fixed end to the free end, that is, the thickness at the free end is the thinnest and the thickness at the fixed end is the thickest. The thinnest free end is conducive to the first sealing part 222 deforming from the free end, and the thickest fixed end is conducive to the first sealing part 222 having greater elastic potential energy after deformation.

[0054] In some embodiments of this application, when the cover 21 is in the open state, the angle between the direction a from the fixed end to the free end and the thickness direction of the cover 21 is α, 20°≤α≤80°; for example, 30°, 40°, 50°, 60°, 70°, etc.

[0055] After the first sealing part 222 contacts the body assembly 10, the body assembly 10 guides the free end of the first sealing part 222. The free end of the first sealing part 222 will move radially along the opening 1311. Within this range, the body assembly 10 has a good guiding effect on the first sealing part 222. In some embodiments of this application, the angle between the direction 'a' from the fixed end to the free end and the depth direction of the body assembly 10 is 45°.

[0056] Furthermore, the angle between the direction α from the fixed end to the free end and the depth direction of the body assembly 10 is closely related to the deformation of the first sealing part 222. The smaller the value of α, the greater the deformation of the first sealing part 222 when the cover 21 rotates relative to the body assembly 10 towards the closed position by the same angle; the larger the value of α, the smaller the deformation of the first sealing part 222 when the cover 21 rotates relative to the body assembly 10 towards the closed position by the same angle. Therefore, when the cover 21 is in the maximum open position, the greater the distance between the free end of the first sealing part 222 and the fixed end of the first sealing part 222 along the depth direction of the body assembly 10, the smaller the angle between the direction a from the fixed end to the free end and the depth direction of the body assembly 10, ensuring that the first sealing part 222 has sufficient elastic potential energy after deformation. Conversely, when the cover 21 is in the maximum open position, the shorter the distance between the free end of the first sealing part 222 and the fixed end of the first sealing part 222 along the depth direction of the body assembly 10, the larger the angle between the direction a from the fixed end to the free end and the depth direction of the body assembly 10, ensuring that the elastic potential energy generated after the deformation of the first sealing part 222 is too large.

[0057] Please refer to Figure 5 As shown, in some embodiments of this application, the first seal 22 further includes a second sealing part 223. The second sealing part 223 protrudes from the surface of the connecting part 221 and presses against the groove wall of the first receiving groove 215. After pressing against the cover 21, the second sealing part 223 seals the gap between the connecting part 221 and the cover 21, reducing the amount of liquid leakage from the body assembly 10 through the gap between the connecting part 221 and the first receiving groove 215.

[0058] It is understandable that, combined with the ring-shaped structure of the connecting part 221 and the ring-shaped structure of the second sealing part 223, the number of the second sealing parts 223 can be multiple. When the cover 21 closes the opening 1311, the multiple second sealing parts 223 are distributed along the opening 1311, that is, the multiple second sealing parts 223 are sequentially nested, and the multiple second sealing parts 223 provide better sealing between the connecting part 221 and the cover 21.

[0059] Please refer to Figure 3 as well as Figure 5 As shown, in some embodiments of this application, the cover 21 includes a cover plate 211, an annular base plate 212, a first annular wing plate 213, and a second annular wing plate 214. The first annular wing plate 213 is fixed to the inner side of the base plate, and the second annular wing plate 214 is fixed to the outer side of the base plate, so that the annular base plate 212, the first annular wing plate 213, and the second annular wing plate 214 form a first receiving groove 215. The cover plate 211 is connected to the first annular wing plate 213 and / or the annular base plate 212. In the embodiments of this application, the annular shape is not limited to a circular ring, but refers to a closed structure formed by connecting the first and last elements in a broad sense.

[0060] The cover 21 is composed of a cover plate 211 and an annular bottom plate 212, a first annular wing plate 213 and a second annular wing plate 214 that form a first receiving groove 215. The cover plate 211 is the main structure of the cover 21 and is used to cover the opening 1311. The annular bottom plate 212, the first annular wing plate 213 and the second annular wing plate 214 form the first receiving groove 215 to connect the first sealing member 22.

[0061] Please refer to Figure 3 As shown, in some embodiments of this application, the hood assembly 20 further includes a fixing member 23. The fixing member 23 is at least partially located within the first receiving groove 215 and is fixedly connected to the annular base plate 212, the first annular wing plate 213, or the second annular wing plate 214. The fixing member 23 fixes the first sealing member 22 within the first receiving groove 215. After the fixing member 23 is connected to the annular base plate 212, the first annular wing plate 213, or the second annular wing plate 214, the fixing member 23 is connected to the hood 21, thereby fixing the first sealing member 22 to the hood 21, allowing the first sealing member 22 to rotate relative to the body assembly 10 with the hood. In a specific embodiment of this application, the fixing member 23 is connected to the annular base plate 212.

[0062] Since the main body is subjected to external force from the first sealing part 222 when the cover 21 closes the opening 1311, the main body of the first sealing part 22 is at least partially located in the first receiving groove 215. The groove wall of the first receiving groove 215 can limit the main body, prevent the main body from shifting after being subjected to external force multiple times, and also prevent the first sealing part 222 from shifting, ensuring that the first sealing part 222 and the body assembly 10 can be squeezed together to form a sealing surface.

[0063] It is understood that in the embodiments of this application, the first receiving groove 215 should be configured as an annular structure corresponding to the shape of the connecting part 221. In some embodiments of this application, the depth of the first receiving groove 215 can fully accommodate the main body and the fixing member 23 to ensure the flatness of the inner side of the cover plate 211.

[0064] In some embodiments of this application, the connecting portion 221 is recessed on the side away from the cover plate 211 to form a connecting groove, which avoids the opening 2211 communicating with the bottom wall of the connecting groove. The fixing member 23 is located in the connecting groove, and the fixing member 23 and the groove wall of the connecting groove are interference fit.
