Description

Technical Field

[0001] The present application relates to the technical field of sealing of top-loading drum washing machines, and in particular to a top-loading drum washing machine. Background Art

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

[0003] Since the axial direction of the drum of a top-loading drum washing machine is perpendicular to the height direction of the top-loading drum washing machine, and the opening of the top-loading drum washing machine is located on the peripheral side of the drum of the top-loading drum washing machine, the centrifugal force of the drum of the top-loading drum washing machine when washing clothes can easily throw the cleaning water onto the cover, and then seep out from the gap between the cover and the body assembly. Utility Model Content

[0004] An embodiment of the present application provides a top-loading drum washing machine, which can form a larger sealing surface between the cover assembly and the body assembly, so that the cover assembly and the body assembly have better sealing performance, and the sealing performance between the cover assembly and the body assembly can still be guaranteed after the cover assembly is deformed.

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

[0006] Based on the top-loading drum washing machine of the embodiment of the present application, when the cover assembly is in the closed position, the cover covers the opening. Since the first sealing member is partially in the first accommodating groove and partially outside the first accommodating groove, the structure of the first sealing member outside the first accommodating groove will be squeezed against the body assembly, so that there is a larger sealing surface between the first sealing member and the body assembly.

[0007] In addition, after the cover of a top-loading drum washing machine is deformed due to long-term use, the sealing surface is formed between the first seal and the body assembly after the first seal and the body assembly are squeezed against each other. Even if the cover is deformed to a certain extent, as long as the first seal and the body assembly can be squeezed against each other when the cover assembly is in the closed position, a sealing surface can be formed, so that the top-loading drum washing machine can still ensure the sealing between the cover and the body assembly after the cover is deformed.

[0008] In some embodiments of the present application, the first sealing component includes a connecting portion and a first sealing portion, the connecting portion is installed in the first accommodating groove; the first sealing portion is at least partially outside the first accommodating groove, the first sealing portion has a fixed end and a free end arranged opposite to each other, the fixed end is connected to the connecting portion, and when the machine cover is in an open state, the direction from the fixed end to the free end is set at an angle to the thickness direction of the machine cover; wherein, when the machine cover is in a closed position, the first sealing portion and the door seal are squeezed against each other to bend the first sealing portion, and the free end is moved radially along the opening, thereby forming a sealing surface between the first sealing portion and the door seal.

[0009] Based on the above embodiment, the connecting portion realizes the connection between the first sealing part and the machine cover, and the direction from the fixed end to the free end of the first sealing part is at an angle to the thickness direction of the machine cover, that is, the extension direction of the first sealing part is at an angle to the thickness direction of the machine cover. After the first sealing part and the body assembly are squeezed 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 along the radial direction of the opening to form a sealing surface between the first sealing part and the body assembly, thereby realizing the sealing of the machine cover assembly and the body assembly.

[0010] In some embodiments of the present application, when the cover is in an open state, the length of the free end of the first sealing portion from the fixed end of the first sealing portion along the thickness direction of the cover is L, 5mm≤L≤1mm; when the cover is in a closed position, the distance of the fixed end of the first sealing portion from the side of the body assembly having the opening is M, 1mm≤M≤3mm.

[0011] Based on the above embodiment, the minimum value of L is greater than the maximum value of M, which ensures that the first sealing portion and the body assembly can be squeezed against each other to form a sealing surface when the cover is in the closed position.

[0012] In some embodiments of the present 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 portion and the body assembly are squeezed against each other, the free end of the first sealing portion first contacts the body assembly, and as the cover gradually rotates toward the closed position, the first sealing portion gradually bends and deforms from the free end to the fixed end. Therefore, the deformation amount of the free end is the largest, and the deformation amount of the fixed end is the smallest. The thickness of the first sealing portion gradually decreases from the fixed end to the free end, that is, the thickness of the free end is the thinnest and the fixed end is the thickest, which is conducive to the first sealing portion starting to deform from the free end and the deformation gradually decreasing.

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

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

[0016] In some embodiments of the present application, the first sealing member further includes a second sealing portion, which is protruded from the surface of the connecting portion and presses against the wall of the first accommodating groove.

[0017] Based on the above embodiment, the second sealing portion seals the gap between the connecting portion and the groove wall of the first accommodating groove after pressing against the groove wall of the first accommodating groove, thereby reducing the leakage of liquid in the body assembly from the gap between the connecting portion and the first accommodating groove.

[0018] In some embodiments of the present application, the machine 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 accommodating groove, and the cover plate is connected to the first annular wing plate and / or the annular base plate.

[0019] Based on the above embodiment, the machine cover is composed of a cover plate and an annular bottom plate, a first annular wing plate and a second annular wing plate that are arranged to form a first accommodating groove. The cover plate is the main structure of the machine 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 accommodating groove to connect the first sealing member.

[0020] In some embodiments of the present application, the cover assembly further includes a fixing member, which is at least partially located in the first receiving groove and fixedly connected to the annular bottom plate, the first annular wing plate, or the second annular wing plate.

[0021] Based on the above embodiment, the first seal is fixed in the first accommodating groove by a fixing member, and the fixing member is connected to the annular base plate, the first annular wing plate or the second annular wing plate to realize the connection between the fixing member and the machine cover, and then the first seal is fixed to the machine cover, so that the first seal rotates with the cover plate relative to the body assembly.

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

[0023] Based on the above embodiment, when the door seal and the first sealing member are squeezed against each other, both the door seal and the first sealing member may be deformed, so that a sealing surface is formed between the door seal and the first sealing member.

[0024] In some embodiments of the present application, the body assembly includes a body and a workbench, the workbench is fixed to the top of the body, the top wall of the workbench has a second accommodating groove, the door seal is sealed to the workbench, and is partially located in the second accommodating groove for abutting the first seal.

[0025] Based on the above embodiment, the portion of the door seal in the second accommodating groove is used to contact the first sealing portion, thereby achieving sealing between the cover assembly and the body assembly when the cover assembly is in the closed position, and the door seal is sealed to the workbench to achieve a sealed connection between the door seal and the body assembly. In this way, the door seal is sealed to both the body assembly and the cover assembly.

[0026] In some embodiments of the present application, the workbench includes a first main body and a second main body, the first main body has the second receiving groove, the second main body is arranged around the circumference of the first main body, and there is 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 is located in the second receiving groove, the second sealing section is located in the sealing gap, and the third sealing section is connected to the machine body.

[0035] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

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

[0037] Since the axial direction of the drum of a top-loading drum washing machine is perpendicular to the height direction of the top-loading drum washing machine, and the opening of the top-loading drum washing machine is located on the peripheral side of the drum of the top-loading drum washing machine, the centrifugal force of the drum of the top-loading drum washing machine when washing clothes can easily throw the cleaning water onto the cover, and then seep out from the gap between the cover and the body assembly.

[0038] To solve the above technical problems, please refer to Figures 1 to 3 As shown, an embodiment of the present application discloses a top-loading drum washing machine, which includes a body assembly 10 and a cover assembly 20. The top wall of the body assembly 10 has an opening 1311, and the body assembly 10 is provided with a door seal 12 around the opening 1311; the cover assembly 20 includes a cover 21 and a first sealing member 22. The cover 21 is hinged to the body assembly 10, and the cover 21 has a first receiving groove 215. When the cover 21 is in the closed position, the first receiving groove 215 is located on the side of the cover 21 facing the body assembly, and the first sealing member 22 is partially located in the first receiving groove 215. When the cover 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 embodiment of the present application, the lack of contact between the first sealing portion 222 and the body assembly 10 refers to the state where the cover 21 is open; the closed position of the cover 21 refers to the contact between the first sealing portion 222 and the body assembly 10, and the position of the cover 21 when the first sealing portion 222 can no longer continue to deform when the cover 21 is not subjected to external force.

[0040] A drum is provided in the body assembly 10 for accommodating items to be washed and washing water. An opening 1311 is used for users to take and place items to be washed in the body assembly 10. The cover assembly 20 is used to cover the opening 1311 of the body assembly 10 when the body assembly 10 is cleaning the items to be washed.

[0041] It can be understood that the cover assembly 20 has a closed position and a maximum open position, and the cover assembly 20 can rotate relative to the body assembly 10 between the closed position and the maximum open position, wherein the closed position refers to the position of the cover assembly 20 relative to the body assembly 10 when the cover assembly 20 covers 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 the cover assembly 20 rotates to the maximum rotatable angle relative to the body assembly 10 from the closed position.

[0042] Based on the top-loading drum washing machine according to the embodiment of the present application, when the cover assembly 20 is in the closed position, the cover 21 covers the opening 1311. Since the first sealing member 22 is partially in the first accommodating groove 215 and partially outside the first accommodating groove 215, at this time, the structure of the first sealing member 22 outside the first accommodating groove 215 will be squeezed against the body assembly 10, so that there is a larger sealing surface between the first sealing member 22 and the body assembly 10.

[0043] In addition, after the top-loading drum washing machine is used for a long time and causes the cover 21 to be deformed, since the sealing surface is formed between the first sealing part 22 and the body assembly 10 after the first sealing part 22 and the body assembly 10 are squeezed against each other, even if the cover 21 undergoes a certain deformation, as long as the first sealing part 222 and the body assembly 10 can be squeezed against each other when the cover assembly 20 is in the closed position, a sealing surface can be formed, so that the top-loading drum washing machine can still ensure the sealing between the cover 21 and the body assembly 10 after the cover 21 is deformed.

[0044] Please refer to Figures 1 to 3 As shown, in some embodiments of the present application, the first sealing member 22 includes a connecting portion 221 and a first sealing portion 222, the connecting portion 221 is installed in the first accommodating groove 215; the first sealing portion 222 is at least partially outside the first accommodating groove 215, and the first sealing portion 222 has a fixed end and a free end that are relatively arranged, and the fixed end is connected to the connecting portion 221. When the machine cover 21 is in an open state, the direction from the fixed end to the free end is set at an angle to the thickness direction of the machine cover 21; wherein, when the machine cover 21 is in a closed position, the first sealing portion 222 and the door seal 12 squeeze each other to bend the first sealing portion 222, and the free end moves radially along the opening 1311, thereby forming a sealing surface between the first sealing portion 222 and the door seal 12.

[0045] The fixed end in the embodiment of the present application refers to one end of an object that is fixed and cannot move or rotate in any direction; the free end refers to the end of an object that is not fixed or restricted, 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 sealing member 22 surrounds the circumference of the opening 1311, that is, at least the first sealing portion 222 is configured as an annular structure. In some embodiments of the present 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, the cover 21 covers the opening 1311. At this time, the first sealing portion 222 and the body assembly 10 are squeezed against each other. Since the direction a from the fixed end to the free end is at an angle to the depth direction of the body assembly 10, that is, the extension direction of the first sealing portion 222 is at an angle to the depth direction of the body assembly 10, the first sealing portion 222 can be bent at any position between the free end and the fixed end after being squeezed against the body assembly 10, and the free end is radially along the opening 1311. When the first sealing portion 222 moves (toward the center of the opening 1311 or toward the edge of the opening 1311), the elastic potential energy generated by the deformation of the first sealing portion 222 makes the first sealing portion 222 close to the body assembly 10. Even if the plane where the body assembly 10 and the first sealing portion 222 cooperate is not flat, the first sealing portion 222 can form a sealing surface with the body assembly 10 under the elastic action of the first sealing portion 222, and the sealing surface has a larger area, thereby ensuring the sealing between the cover 21 and the body assembly 10.

[0048] Furthermore, even if the cover 21 of a top-loading drum washing machine is deformed due to long-term use, the sealing surface is formed between the first sealing portion 222 and the body assembly 10 after being compressed by the first sealing portion 222 and the body assembly 10 and then bent at any position between the free end and the fixed end. Therefore, even if the cover 21 is deformed to a certain extent, the sealing surface can be formed as long as the first sealing portion 222 and the body assembly 10 can be compressed by each other when the cover 21 is in the closed position. This ensures that the top-loading drum washing machine can still maintain the sealing between the cover 21 and the body assembly 10 even after the cover 21 is deformed. Furthermore, there is no need to increase the closing pressure of the top-loading drum washing machine, ensuring that users have a good experience when opening and closing the cover 21.

[0049] In some embodiments of the present application, when the cover 21 is in the open state, the length of the free end of the first sealing portion 222 from the fixed end of the first sealing portion 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 between the fixed end of the first sealing portion 222 and 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, which ensures that the first sealing portion 222 and the body assembly 10 can be squeezed against each other to form a sealing surface when the cover 21 is in the closed position; combined with the above-mentioned configuration of the first sealing portion 222 as an annular structure, it can be seen that the first sealing ring is an annular surface, and from the above-mentioned value range of L and the value range of M, it can be seen that the ring width of the sealing surface formed between the first sealing portion 222 and the body assembly 10 is at least 2 mm and at most 9 mm.

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

[0052] Similarly, if M is too large, the first sealing portion 222 will have a longer distance in the depth direction of the body component 10 in order to be squeezed with the body component 10 to form, but if M is too small, the first sealing portion 222 will need to bend at a larger angle during the deformation process. In a specific embodiment of the present application, M is 2 mm. At this time, the first sealing portion 222 only needs to bend at a suitable angle during the deformation process, and only part of the first sealing portion 222 is bent; combined with the above L of 7 mm, a sealing ring with a width of 5 mm is formed between the first sealing portion 222 and the body component 10.

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

[0054] In some embodiments of the present 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 portion 222 contacts the body assembly 10, the body assembly 10 guides the free end of the first sealing portion 222. The free end of the first sealing portion 222 moves radially along the opening 1311. Within this range, the body assembly 10 effectively guides the first sealing portion 222. In some embodiments of the present 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] In addition, the size of the angle between the direction a from the fixed end to the free end and the depth direction of the body assembly 10 has a great relationship with the deformation amount of the first sealing portion 222. The smaller the value of α, the greater the deformation amount of the first sealing portion 222 when the cover 21 rotates toward the closed position by the same angle relative to the body assembly 10; the larger the value of α, the smaller the deformation amount of the first sealing portion 222 when the cover 21 rotates toward the closed position by the same angle relative to the body assembly 10. Therefore, when the cover 21 is in the maximum open position, the longer the length of the free end of the first sealing part 222 from the fixed end of the first sealing part 222 along the depth direction of the body assembly 10 is, 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 is, which can ensure 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 length of the free end of the first sealing part 222 from the fixed end of the first sealing part 222 along the depth direction of the body assembly 10 is, 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 is, which can ensure that the elastic potential energy generated after the first sealing part 222 is too large.

[0057] Please refer to Figure 5 As shown, in some embodiments of the present application, the first sealing member 22 further includes a second sealing portion 223, which is protruded from the surface of the connecting portion 221 and presses against the groove wall of the first receiving groove 215. After pressing against the machine cover 21, the second sealing portion 223 seals the gap between the connecting portion 221 and the machine cover 21, thereby reducing the amount of liquid in the body assembly 10 leaking from the gap between the connecting portion 221 and the first receiving groove 215.

[0058] It can be understood that, combined with the above-mentioned shape of the connecting portion 221 being an annular structure, the second sealing portion 223 being an annular structure, the number of the second sealing portions 223 can be multiple, and when the machine cover 21 covers the opening 1311, the multiple second sealing portions 223 are distributed along the opening 1311, that is, the multiple second sealing portions 223 are sequentially arranged, and the multiple second sealing portions 223 have better sealing between the connecting portion 221 and the machine cover 21.

[0059] Please refer to Figure 3 as well as Figure 5 As shown, in some embodiments of the present 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. The annular base plate 212, the first annular wing plate 213, and the second annular wing plate 214 form a first receiving groove 215, and the cover plate 211 is connected to the first annular wing plate 213 and / or the annular base plate 212. The annular in the embodiments of the present application is not limited to a circular ring, but refers to a closed structure formed by connecting the first and the second ends in a broad sense.

[0060] The machine 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 are arranged to form a first accommodating groove 215. The cover plate 211 is the main structure of the machine 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 are arranged to form a first accommodating groove 215 to connect the first sealing member 22.

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

[0062] Since the main body will be subjected to external force from the first sealing part 222 when the machine cover 21 covers the opening 1311, the main body of the first sealing part 22 is at least partially located in the first accommodating groove 215. The groove wall of the first accommodating groove 215 can limit the main body to prevent the main body from being offset after being subjected to external force multiple times, and also prevent the first sealing part 222 from being offset, thereby ensuring that the first sealing part 222 and the body assembly 10 can squeeze each other to produce a sealing surface.

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

[0064] In some embodiments of the present application, a connecting groove is formed on the side of the connecting portion 221 away from the cover plate 211, and the opening 2211 is connected to the bottom wall of the connecting groove.
