Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a door seal assembly and a drum washing machine. Background Technology

[0002] Front-loading washing machines, with their advantages of gentler wear and tear on clothes, higher cleaning power, and water conservation, have become essential household appliances for daily laundry care. However, existing front-loading washing machines suffer from insufficient sealing between the door seal and the door glass. During operation, the high-speed rotation of the inner drum creates pressure in the water. If the door seal and door glass are not tightly sealed, or the sealing depth does not meet design requirements, water can easily seep through the gaps, causing leakage. Leaking door seals not only affect the normal operation of the washing machine but can also lead to a damp environment around the machine, potentially causing secondary problems such as damage to electrical components due to moisture, and waterlogging of the floor. This not only impacts the user experience but can also result in potential financial losses. Utility Model Content

[0003] The main purpose of this utility model is to propose a door seal assembly and a drum washing machine, which aims to solve the problem of water leakage caused by insufficient adhesion between the door seal and the door glass in existing drum washing machines.

[0008] Preferably, the sealing adjustment member includes a bladder and a filling part. The bladder is disposed within the installation space. The bladder is flexibly configured and forms a sealing chamber therein. The filling part fills the sealing chamber. The filling part is configured as a deformable part so that the sealing adjustment member switches between deformation and reset when the volume and / or shape of the filling part changes.

[0009] Preferably, the filling portion comprises one of gas, liquid, and elastic solid.

[0010] Preferably, the volume of the filling portion occupies more than 80% of the volume of the sealed chamber.

[0011] Preferably, the sealing adjustment component further includes a plurality of support ribs, which are disposed on the outer side wall of the sealing adjustment component and located on the side of the sealing adjustment component away from the door body. The plurality of support ribs are arranged side by side at intervals in the radial direction of the clothing inlet, and each support rib extends circumferentially along the clothing inlet.

[0012] Preferably, the sealing lip has an inner side facing away from the door body;

[0013] The door seal assembly includes a mounting groove, which is at least located on the inner side and extends circumferentially along the clothing loading opening to form the mounting space.

[0014] The sealing adjustment element is disposed in the mounting groove, and the cross-sectional shape of the mounting groove in the circumferential direction is adapted to the cross-sectional shape of the sealing adjustment element.

[0015] Preferably, the door seal further includes a door seal body, the door seal body being arranged around the clothing inlet, and the sealing lip being arranged around the door seal body and located on the side of the door seal body facing the door.

[0016] The mounting groove is provided at the connection between the door seal body and the sealing lip, and part of it is located on the inner side and the other part is located on the door seal body;

[0017] The sealing lip has a protruding edge at the position corresponding to the mounting groove opening. The protruding edge covers part of the groove opening and extends circumferentially along the clothing inlet to block the sealing adjustment component.

[0018] Preferably, the mounting groove has a first sidewall located on the door seal body and a second sidewall located on the inner side;

[0019] The sealing adjustment member has a first end and a second end opposite to each other. The first end abuts against the first sidewall, and the second end has a connecting portion protruding from it. The connecting portion has a first side and a second side adjacent to each other. The first side abuts against the second sidewall, and the second side is in contact with the protruding edge.

[0020] Preferably, the first end is adhered and fixed to the first sidewall; and / or,

[0022] Preferably, the mounting groove has a first bottom wall on the door seal body and a second bottom wall on the inner side, the first bottom wall and the second bottom wall are adjacent to each other, and an arc-shaped bottom wall is provided between the first bottom wall and the second bottom wall;

[0023] The sealing adjustment member has two adjacent side surfaces, and an arc-shaped transition surface is provided between the two adjacent side surfaces. When the sealing adjustment member is accommodated in the mounting groove, the two side surfaces are respectively in contact with the first bottom wall and the second bottom wall, and the arc-shaped transition surface is in contact with the arc-shaped bottom wall.

[0024] The first bottom wall is bonded and fixed to the corresponding surface.

[0025] This utility model also proposes a drum washing machine, including the above-mentioned door seal assembly.

[0026] The technical solution provided by this utility model has at least the following advantages:

[0027] This utility model provides a door seal assembly, including a door seal and a sealing adjustment component. The door seal ring is located at the clothing inlet and includes a sealing lip. When the door closes the clothing inlet, the sealing lip abuts against the door, thus sealing the door seal against the door. It is understood that in scenarios where the washing machine is fully loaded or the water level is high, the tumbling water and clothing exert a significant impact on the lower side of the door, easily leading to insufficient contact between the sealing lip and the lower side of the door. On the side away from the door, an installation space is formed at least on the sealing lip, corresponding at least to the lower side of the clothing inlet. A sealing adjustment component is installed within the installation space, and the sealing adjustment component is deformable. When the door is opened, the sealing adjustment component resets and occupies part of the installation space. When the door is closed, the sealing lip is squeezed by the door, causing the sealing adjustment component to deform and fill the installation space. This supports the sealing lip and presses it tightly against the door, increasing the contact between the sealing lip and the door. This, in turn, improves the strength and sealing performance of the door seal. This allows it to adapt to different washing conditions and achieve adaptive sealing of the door seal based on the water level and pressure inside the washing machine drum.

[0043] A front-loading washing machine typically consists of a cabinet, inner tub, outer tub, and door. It has a door seal, with its front end fixed to the front door panel and its rear end connected to the washing machine tub. To use it, open the washing machine door, place the clothes in the inner tub, and then close the door. At this point, the door glass and the door seal lip are sealed together, creating a closed space inside the washing machine, allowing it to begin operation.

[0044] In order to improve the fit between the sealing lip and the door body 300, this utility model improves the door seal assembly 100 of the drum washing machine 1000. The specific structure of the door seal assembly 100 is described below with reference to the accompanying drawings.

[0045] Please see Figures 1 to 5The drum washing machine 1000 includes a body 200 and a door 300. A clothes handling chamber 201 is formed inside the body 200, and a clothes inlet 202 communicating with the clothes handling chamber 201 is formed on the body 200. Users can place clothes in the clothes handling chamber 201 or take out clothes through the clothes inlet 202.

[0046] The door 300 includes a door housing 301 and an observation window 302. The door housing 301 is generally circular. One side of the door housing 301 is hinged to the main body 200 via a pivot, which allows the clothing loading port 202 to be opened or closed when the door housing 301 rotates around the pivot. The observation window 302 is located on the door housing 301 and is situated on the side of the door housing 301 facing the clothing loading port 202.

[0047] The drum washing machine 1000 also includes a door seal assembly 100, which is located at the clothes loading port 202 of the drum washing machine 1000 and is positioned corresponding to the door 300. The door seal assembly 100 includes a door seal 1 and a sealing adjustment element 2. The door seal 1 is an annular structure made of elastic material and is annularly positioned at the clothes loading port 202.

[0048] The door seal 1 includes a door seal body 11 and a sealing lip 12. The door seal body 11 is arranged around the clothing inlet 202, and the sealing lip 12 is located on the side of the door seal body 11 facing the door 300 and is arranged around the inner circle of the door seal body 11. When the door 300 closes the clothing inlet 202, the sealing lip 12 abuts against the door 300, thereby sealing the door seal body 11 against the door 300.

[0049] Understandably, while the sealing lip 12 abuts against the door 300 and seals when the door 300 is closed, the tumbling water and clothes exert significant impact on the door 300 when the washing machine is fully loaded or at high water levels. Since water and clothes accumulate at the bottom of the drum of the washing machine 1000, the impact primarily affects the underside of the door 300. These impacts during the washing process can create gaps between the door seal 1 and the door 300, leading to water leakage.

[0050] In this invention, an installation space is formed on at least the sealing lip 12 on the side opposite to the door body 300, and the installation space is provided at least below the clothing delivery opening 202. The door seal assembly 100 also includes a sealing adjustment member 2, which is disposed within the installation space.

[0051] The sealing adjustment component 2 is deformable. When the door 300 is opened, the sealing adjustment component 2 returns to its original position and occupies part of the installation space, pushing the sealing lip 12 towards the door 300. When the door 300 is closed, the sealing adjustment component 2 is compressed by the door 300, causing it to deform and fill the installation space. This supports the sealing lip 12 and presses it tightly against the door 300, increasing the amount of contact between the sealing lip 12 and the door 300. This, in turn, improves the strength and sealing performance of the door seal 1. This allows it to adapt to different washing conditions and achieve adaptive contact of the door seal 1 based on the water level and pressure inside the washing machine drum.

[0052] This invention does not impose specific limitations on the placement of the sealing adjustment member 2. The sealing adjustment member 2 can be placed at a local location corresponding to the clothing inlet 202; the sealing adjustment member 2 can be placed at all locations around the clothing inlet 202.

[0053] This utility model does not impose specific limitations on the arrangement of the sealing adjustment element 2. The sealing adjustment element 2 can be arranged in a point-like manner; for example, multiple sealing adjustment elements 2 can be arranged at intervals along the circumference of the clothing inlet 202. The sealing adjustment element 2 can also be arranged in a strip-like manner, extending along the circumference of the clothing inlet 202.

[0054] In one embodiment, please refer to Figure 2 The installation space is set on the lower half of the clothing inlet 202 and extends circumferentially along the clothing inlet 202. That is to say, the sealing adjustment member 2 is set on the lower half of the clothing inlet 202 and extends circumferentially along the clothing inlet 202.

[0055] Continuing from the previous statement that "since water and clothes are deposited at the bottom of the drum of the washing machine 1000, the impact is mainly directed at the lower side of the door 300", a sealing adjustment element 2 is provided at the lower half of the corresponding clothes inlet 202, and the sealing adjustment element 2 is provided to extend circumferentially along the clothes inlet 202. This ensures that during the washing process, at least at the lower half of the clothes inlet 202, the amount of contact between the sealing lip 12 and the door 300 is increased, thereby preventing water leakage from the door seal 1.

[0056] In one embodiment, please refer to Figures 3 to 5 The sealing adjustment member 2 includes a bladder 21 and a filling part 22. The bladder 21 is disposed in the installation space. The bladder 21 is flexibly arranged and forms a sealing chamber 211 therein. The filling part 22 fills the sealing chamber 211. The filling part 22 is configured as a deformable shape so that the sealing adjustment member 2 switches between deformation and reset when the volume and / or shape of the filling part 22 changes.

[0057] In this embodiment, a filling portion 22 is provided in a flexible bladder 21 to form a sealing adjustment member 2. Since the filling portion 22 is configured as a deformable shape, the shape of the sealing adjustment member 2 can be changed by the change in the volume and / or shape of the filling portion 22 itself, thereby switching between deformation and reset.

[0058] Specifically, the capsule 21 is made of highly elastic and aging-resistant materials, such as rubber (nitrile rubber, silicone rubber, etc.) or polymer films, ensuring that it can recover its original shape after deformation and possesses certain resistance to media (such as oil resistance, water resistance, and chemical corrosion resistance). In this way, the capsule 21 can serve as a sealed chamber 211, enclosing the deformed parts within it. Simultaneously, the outer side of the capsule 21 can directly contact the sealing surface, achieving initial sealing through its flexible fit; and its flexibility ensures that it can change shape according to changes in the sealing gap under the action of deformation.

[0059] This invention does not impose specific limitations on the form of the filling part 22. The filling part 22 includes one of gas, liquid, and elastic solid. In one embodiment, the filling part 22 is set as a gas, such as air, and the volume of the capsule 21 is changed by inflating or deflating the gas, thereby achieving sealing adjustment. In another embodiment, the filling part 22 is set as an elastic solid, such as foamed rubber or silicone. Because it has its own elastic deformation capability, when it is squeezed by external force, the filling part 22 deforms and fills the installation space, so that the sealing lip 12 can completely fit the door body 300, increasing the amount of contact between the sealing lip 12 and the door body 300.

[0060] Preferably, in one embodiment, the filling portion 22 is made of liquid, such as water, by injecting water into the bladder 21, with the water volume occupying a portion of the space in the bladder 21. When the door 300 is opened, water deposits at the bottom of the bladder 21, thereby opening the partial sealing lip 12. When the door 300 is closed, the bladder 21 is compressed by the door 300, allowing water to fill the entire bladder and the installation space. At this time, the bladder 21 supports the sealing lip 12 from the inside, so that the sealing lip 12 can completely fit the door 300 at all points, increasing the amount of contact between the sealing lip 12 and the door 300, thereby improving the strength and sealing performance of the door seal 1.

[0061] As mentioned above, "When the door 300 is closed, the bladder 21 is squeezed by the door 300, so that the filling part 22 inside can fill the entire bladder 21". In order to provide deformation space for the filling part 22, but at the same time meet the requirement of opening the sealing lip 12, in one embodiment, the volume of the filling part 22 occupies more than 80% of the volume of the sealing chamber 211.

[0062] For example, when the filling part 22 is set to liquid, the volume of the liquid occupies 80% of the volume of the sealed chamber 211, thereby providing space for liquid flow when the bladder 21 is squeezed when the door is closed.

[0063] When the filling part 22 is set as an elastic solid, in order to ensure the smooth deformation and reset of the sealing adjustment member 2, the volume of the elastic solid occupies 100% of the volume of the sealing chamber 211. That is to say, the elastic solid fills the entire sealing chamber 211 and forms a whole, thereby making the deformation and reset of the sealing adjustment member 2 smoother.

[0064] It is understood that, due to the flexible design of the bladder 21, the filling portion 22 inside can deform in any direction when the door is squeezed during closing. To increase the support of the sealing adjustment member 2 for the sealing lip 12, in one embodiment, please refer to... Figure 6 The sealing adjustment member 2 also includes a support portion 23, which is disposed on the sealing adjustment member 2 and located on the side of the sealing adjustment member 2 away from the door body 300. By providing the support portion 23, the support strength of the sealing adjustment member 2 on the side away from the door body 300 is increased. This allows the sealing adjustment member 2 to provide unidirectional support force to the inner surface 121, thereby opening the sealing lip 12 toward the door body 300.

[0065] This utility model does not impose specific limitations on the form of the support portion 23. In one embodiment, the sealing adjustment member 2 extends circumferentially along the clothing inlet 202. The support portion 23 includes a plurality of support ribs 231 disposed on the outer wall of the sealing adjustment member 2. The plurality of support ribs 231 are arranged side by side at intervals in the radial direction of the clothing inlet 202, and each support rib 231 extends circumferentially along the clothing inlet 202.

[0066] Preferably, the plurality of support ribs 231 include a first support rib located on the periphery and a second support rib located in the middle. In the radial direction of the clothing inlet 202, the width of the second support rib is greater than the width of the first support rib. It is understood that when the filling part 22 is made of liquid, the bladder 21 is prone to collapse from its lower part under gravity. By increasing the width of the second support rib, greater support is provided to the middle part of the sealing adjustment member 2, which not only prevents the bladder 21 from collapsing but also ensures that the supporting force provided by the sealing adjustment member 2 to various points inside the sealing lip 12 is relatively balanced.

[0067] To improve the installation stability of the sealing adjustment element 2, in one embodiment, please refer to... Figures 7 to 8The sealing lip 12 has an inner side 121 facing away from the door body 300. The door seal assembly 100 includes a mounting groove 3, which is at least located on the inner side 121 and extends circumferentially along the clothing delivery opening 202 to form an installation space. A sealing adjustment member 2 is disposed within the mounting groove 3, and the cross-sectional shape of the mounting groove 3 in the circumferential direction is adapted to the cross-sectional shape of the sealing adjustment member 2.

[0068] In this embodiment, by providing an installation groove 3 on the door seal 1, the sealing adjustment member 2 can be inserted into the installation groove 3, improving the installation stability of the sealing adjustment member 2. On the other hand, the installation groove 3 provides installation space for the sealing adjustment member 2, making the assembly of the sealing adjustment member 2 more compact.

[0069] Preferably, the door seal 1 further includes a door seal body 11, which is arranged around the clothing inlet 202. A sealing lip 12 is arranged around the inner ring of the door seal body 11 and is located on the side of the door seal body 11 facing the door 300. The mounting groove 3 is provided at the connection between the door seal body 11 and the sealing lip 12, and part of it is located on the inner side 121 and the other part is located on the door seal body 11.

[0070] In other words, part of the mounting groove 3 is located on the inner side 121, and the other part is located on the door seal body 11. When the sealing adjustment component 2 is installed into the mounting groove 3, part of the sealing adjustment component 2 is located on the inner side 121, and part is located on the door seal body 11. In this way, the sealing adjustment component 2 is snapped into place at the connection between the sealing lip 12 and the door seal body 11, thereby improving the installation stability of the sealing adjustment component 2.

[0071] During the washing process, to prevent the sealing adjustment element 2 from detaching from the groove of the mounting groove 3 due to impact and vibration, in one embodiment, please refer to... Figure 7 and Figure 8 The sealing lip 12 has a protruding edge 13 at the position corresponding to the groove opening of the mounting groove 3. The protruding edge 13 covers part of the groove opening and extends circumferentially along the clothing inlet 202 to prevent the sealing adjustment component 2 from disengaging. By setting the protruding edge 13, the sealing adjustment component 2 is prevented from disengaging from the groove opening.

[0072] Following the previous statement that "the cross-sectional shape of the mounting groove 3 in the circumferential direction is adapted to the cross-sectional shape of the sealing adjustment member 2," in one embodiment, the mounting groove 3 has a first sidewall 31 located on the door seal body 11 and a second sidewall 32 located on the inner sidewall 121. The sealing adjustment member 2 has a first end 2a and a second end 2b opposite to each other. The first end 2a abuts against the first sidewall 31, and a connecting portion 24 protrudes from the second end 2b. The connecting portion 24 has a first sidewall and a second sidewall adjacent to each other. The first sidewall abuts against the second sidewall 32, and the second sidewall is in contact with the protruding edge 13. The rigidity of the connecting portion 24 is greater than that of the sealing adjustment member 2.

[0073] In one embodiment, the first end 2a is adhered and fixed to the first sidewall 31. Preferably, the first end 2a is adhered and fixed to the first sidewall 31 with waterproof adhesive. This further prevents the sealing adjustment member 2 from detaching.

[0074] In one embodiment, the second side surface is bonded and fixed to the protruding edge 13. Preferably, the second side surface is bonded and fixed to the protruding edge 13 with waterproof adhesive. This further prevents the sealing adjustment member 2 from detaching.

[0075] It should be noted that the above two technical features can be set individually or simultaneously. Specifically, in one embodiment, both technical features are set simultaneously.

[0076] Following the previous statement that "the cross-sectional shape of the mounting groove 3 in the circumferential direction is adapted to the cross-sectional shape of the sealing adjustment member 2," in one embodiment, the mounting groove 3 has a first bottom wall 33 located on the door seal body 11 and a second bottom wall 34 located on the inner side surface 121, with the first bottom wall 33 and the second bottom wall 34 adjacent to each other. The sealing adjustment member 2 has adjacent two side surfaces 2c, which, when the sealing adjustment member 2 is accommodated in the mounting groove 3, respectively abut against the first bottom wall 33 and the second bottom wall 34.

[0077] Due to manufacturing and assembly tolerances, gaps may occur between the sealing adjustment member 2 and the mounting groove 3 at the connection between the corresponding door seal body 11 and the sealing lip 12, resulting in uneven support force provided by the sealing adjustment member 2 to the sealing lip 12 when it deforms.

[0078] In one embodiment, an arc-shaped bottom wall 35 is provided between the first bottom wall 33 and the second bottom wall 34. An arc-shaped transition surface 2d is provided between the adjacent two side surfaces 2c of the sealing adjustment member 2. When the sealing adjustment member 2 is accommodated in the mounting groove 3, the arc-shaped transition surface 2d fits against the arc-shaped bottom wall 35. By providing the arc-shaped bottom wall 35 and the arc-shaped transition surface 2d, the sealing adjustment member 2 fits against the groove wall of the mounting groove 3 at all points, thereby providing relatively uniform support force to the sealing lip 12 at all points when the sealing adjustment member 2 deforms.

[0079] Similarly, to further improve the installation stability of the sealing adjustment component 2, in one embodiment, the first bottom wall 33 is bonded and fixed to the corresponding surface 2c. Preferably, the first bottom wall 33 and the corresponding surface 2c are bonded and fixed with waterproof adhesive. This further prevents the sealing adjustment component 2 from detaching.

[0080] This utility model also provides a drum washing machine 1000, please refer to [link / reference]. Figure 1 and Figure 2The drum washing machine 1000 includes a body 200 and a door 300. A clothes handling chamber 201 is formed inside the body 200, and a clothes inlet 202 communicating with the clothes handling chamber 201 is formed on the body 200, allowing the user to place clothes into the clothes handling chamber 201 or remove clothes through the clothes inlet 202. The door 300 is hinged to the body 200 via a pivot, used to rotate and open or close the clothes inlet 202. The door 300 includes a door shell 301 and an observation window 302.

[0081] The drum washing machine 1000 also includes a door seal assembly 100, which includes a door seal 1 and a sealing adjustment element 2. The door seal 1 is an annular structure made of elastic material and includes a door seal body 11 and a sealing lip 12. The door seal body 11 is arranged around the clothes loading opening 202, and the sealing lip 12 is located on the side of the door seal body 11 facing the door body 300 and is arranged around the inner ring of the door seal body 11. When the door body 300 closes the clothes loading opening 202, the sealing lip 12 abuts against the door body 300, thereby sealing the door seal body 11 with the door body 300.

[0082] It should be noted that the door seal assembly 100 is configured as described above, which includes all the technical features of the door seal assembly 100. Therefore, the drum washing machine 1000 also includes all the technical features of the door seal assembly 100, and thus has the technical effects brought about by all the technical features described above.

[0083] On the side opposite to the door body 300, an installation space is formed at least on the sealing lip 12, and the installation space is provided at least below the clothing delivery opening 202. The door seal assembly 100 also includes a sealing adjustment element 2, which is disposed within the installation space.

[0084] The sealing adjustment component 2 is deformable. When the door 300 is opened, the sealing adjustment component 2 returns to its original position and occupies part of the installation space, pushing the sealing lip 12 towards the door 300. When the door 300 is closed, the sealing adjustment component 2 is compressed by the door 300, causing it to deform and fill the installation space. This supports the sealing lip 12 and presses it tightly against the door 300, increasing the amount of contact between the sealing lip 12 and the door 300. This, in turn, improves the strength and sealing performance of the door seal 1. This allows it to adapt to different washing conditions and achieve adaptive contact of the door seal 1 based on the water level and pressure inside the washing machine drum.

[0085] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
