Description

Protruding structure, door seal, door, drum assembly and laundry treating apparatus The present application claims priority to Chinese Patent Application CN202410649864X, filed on May 23, 2024, entitled “Door seal, drum assembly and laundry treating apparatus”, and Chinese Patent Application CN2024108103692, filed on June 21, 2024, entitled “Protruding structure of door, door and laundry treating apparatus”, the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0001] The present application relates to the field of laundry treating apparatus, and in particular provides a protruding structure, a door seal, a door, a drum assembly and a laundry treating apparatus. BACKGROUND

[0002] In the design of laundry treating apparatuses such as washing machines, some apparatuses have a design of a closed inner drum, i.e., the surface of the inner drum is no longer provided with water-permeable holes. This design aims to prevent the washing water from flowing freely in the gap between the inner drum and the outer drum during washing, thereby reducing the risk of dirt entering the inner drum and contacting the surface of the laundry, and improving the washing effect.

[0003] However, in order to ensure that the inner drum can rotate freely, a certain gap still needs to be left between the inner and outer drums. This gap, although a necessary mechanical structure, becomes a channel for the leakage of washing liquid and water. Especially when the washing machine rotates at high speed, the pressure of the water flow will exacerbate this problem, thereby reducing the amount of washing water in the inner drum and affecting the washing effect.

[0004] Accordingly, there is a need in the art for a new door seal, drum assembly and laundry treating apparatus to solve the above problems.

[0005] Embodiment I: CN202410649864X

[0006] The present application aims to solve the above technical problems, i.e., to solve the problem of how to reduce the phenomenon of water reduction during washing of existing laundry treating apparatuses.

[0007] In a first aspect, the present application provides a door seal of a laundry treating apparatus, characterized in that the door seal comprises: a door seal body, the door seal body being configured to form a seal with a door and an outer drum of the laundry treating apparatus; and a blocking structure formed on the door seal body, the blocking structure being configured to block a gap between an inner drum opening and an outer drum opening of the laundry treating apparatus.

[0008] In the above technical solution, the only leakage point of the washing water is the gap between the inner drum opening and the outer drum opening, and the blocking structure formed on the door seal body blocks the gap between the inner drum opening and the outer drum opening, so that the blocking structure can block the front end of the gap between the inner drum and the outer drum that causes water leakage, and most of the water cannot enter the gap between the inner drum and the outer drum, thereby obviously reducing the possibility of reducing the amount of washing water in the inner drum, and further improving the washing effect. On this basis, combined with the flexible characteristics of the door seal, when the inner drum jumps and contacts the blocking structure, the door seal can bend or deform, thereby absorbing the impact caused by the inner drum jumping through deformation, thereby ensuring that the inner drum opening and the blocking structure can maintain good contact even when the inner drum is running at high speed. The gap between the structure and the inner drum opening can be smaller, thereby reducing the possibility of washing water flowing out from the gap, thereby improving the washing effect.

[0009] In the preferred technical solution of the door seal of the above laundry treatment apparatus, the blocking structure is located inside the gap.

[0010] In the above technical solution, the blocking structure is located inside the gap, which can minimize external interference, such as making it not directly exposed to the surface of the laundry that may form frequent collisions during washing, reducing the deformation of the blocking structure caused by collisions, thereby ensuring its persistent blocking effect and functional stability. In addition, the blocking structure located inside the gap makes the connection between the blocking structure and the door seal body more convenient and reliable.

[0011] In the preferred technical solution of the door seal of the above laundry treatment apparatus, the gap is towards the annular radial center thereof, and the blocking structure comprises a first water blocking ring connected with the door seal body, the first water blocking ring being arranged to block the gap in the radial direction.

[0012] In the above technical solution, since the gap is towards the annular radial center thereof, most of the washing water needs to flow from the radial direction to the gap before it can leak out, and in this case, the first water blocking ring of the present application is arranged to block the gap in the radial direction, effectively preventing the possibility of water flow from the radial direction into the inside of the gap, especially for the upper gap. The effect is more obvious, thereby further reducing the waste of washing water.

[0013] In the preferred technical solution of the door seal of the above laundry treatment apparatus, the blocking structure further comprises a second water blocking ring, the second water blocking ring being arranged on one side of the first water blocking ring close to the inner drum opening, and the second water blocking ring, the first water blocking ring and the door seal body forming an annular groove.

[0014] In the technical scheme, the washing water entering the gap first flows into the annular groove, the washing water flowing upwards first enters the upper annular groove from the gap, and the washing water changes the flow path under the blocking of the annular groove and flows to the gap, so as to return to the inner drum to participate in washing. The washing water flowing downwards enters the lower annular groove from the gap, and the amount of washing water entering the gap between the inner drum and the outer drum can be reduced under the blocking of the annular groove, so as to avoid dirt at the gap between the inner drum and the outer drum.

[0015] In the preferred technical scheme of the door seal of the laundry treating apparatus, the second water blocking ring is spaced apart from the end of the first water blocking ring and the inner drum opening.

[0016] In the technical scheme, the inner drum can rotate efficiently, and the washing work can be effectively performed.

[0017] In the preferred technical scheme of the door seal of the laundry treating apparatus, the spacing is 2mm-4mm.

[0018] In the technical scheme, the gap can be smaller under the premise of efficient rotation of the inner drum and no influence on the washing work, so that the risk of washing water leakage can be greatly reduced.

[0019] In the preferred technical scheme of the door seal of the laundry treating apparatus, the door seal body comprises a main body, a first connecting part and a second connecting part connected to the main body, the first connecting part is used for wrapping the outer drum opening, the second connecting part is used for sealing with the door, and the first water blocking ring is connected to the part of the first connecting part inside the outer drum opening.

[0020] In the technical scheme, the door seal and the outer drum can be tightly connected, and the first connecting part can extend into the gap from the outer drum opening, so that the extending part can block part of the gap. By adjusting the thickness of the first connecting part or the tightness of wrapping the outer drum opening, the spacing between the first connecting part and the inner drum opening can be small, so that the possibility of washing water flowing out of the gap can be further reduced.

[0021] In the preferred technical scheme of the door seal of the laundry treating apparatus, the door comprises a door body and a protruding structure protruding from the door body, the door seal body is used for sealing with the protruding structure, and the protruding structure is closer to the inner side of the inner drum of the laundry treating apparatus than the gap.

[0022] In the above technical solution, the protruding structure can block a part of the washing water to flow back to the inner side of the inner drum, so that the washing water can participate in the washing process again. The washing water flowing to the gap is blocked by the shielding structure, so that the amount of washing water flowing into the inner side of the gap is reduced. Therefore, the above arrangement can greatly reduce the waste of washing water, thereby improving the washing effect. On the other hand, the protruding structure can also push the clothes back to the inner side of the inner drum to participate in the washing, thereby improving the washing effect.

[0023] In another aspect, the application also provides a drum assembly, which comprises an outer drum and a closed inner drum rotatably arranged inside the outer drum, and further comprises the door seal of any one of the above embodiments.

[0024] In the above technical solution, when the drum assembly is applied to the laundry treatment device, the waste of water can be reduced, and the phenomenon that the water is washed less and less can be reduced, thereby improving the washing effect of the laundry.

[0025] In another aspect, the application also provides a laundry treatment device, which comprises the above drum assembly.

[0026] In the above technical solution, when the drum assembly is applied to the laundry treatment device, the waste of water can be reduced, and the phenomenon that the water is washed less and less can be reduced, thereby improving the washing effect of the laundry.

[0027] Embodiment two: CN2024108103692

[0028] The application aims to solve the above technical problems, i.e., how to reduce the phenomenon that the water amount is reduced during washing of the existing laundry treatment device.

[0029] In the first aspect, the application provides a protruding structure of a door of a laundry treatment device, characterized in that the laundry treatment device comprises an outer drum and an inner drum, the inner drum is rotatably arranged inside the outer drum, and a gap is formed between an inner drum opening of the inner drum and an outer drum opening of the outer drum; an end face of the protruding structure faces the inner side of the inner drum, the end face is closer to the inner side of the inner drum than the gap, and the end face is formed with a flow guide structure for guiding water to the inner drum.

[0030] In the above technical solution, when the protruding structure of the door is applied to the laundry treating apparatus, the end surface is closer to the inner side of the inner drum than the gap, so that during washing, most of the washing water in the inner drum first contacts the end surface, and when the washing water reaches the end surface, the flow guide structure of the end surface re-directs the washing water into the inner drum without leaking into the gap, thereby reducing the phenomenon of water reduction during washing of the laundry treating apparatus and improving the washing effect.

[0031] In the optional technical solution of the protruding structure of the door of the laundry treating apparatus, the flow guide structure comprises an inclined surface.

[0032] In the above technical solution, by simply modifying the protruding structure, the washing water can be directed to the inner side of the inner drum, thereby simplifying the structure while avoiding water waste.

[0033] In the optional technical solution of the protruding structure of the door of the laundry treating apparatus, the end surface is formed with a tapered groove, and the inclined surface constitutes a sidewall of the tapered groove.

[0034] In the above technical solution, when the washing water reaches the end surface, it enters the tapered groove, and after the water flow reaches the bottom of the tapered groove, it continues to flow along the sidewall of the tapered groove and flows out of the opening of the tapered groove. Due to the inclined shape of the sidewall of the tapered groove, the direction of the water flow is effectively controlled, so that the water flow flows towards the inner side of the inner drum away from the gap, and the washing water is re-directed into the inner drum for washing, thereby improving the water flow introduction efficiency. In addition, since the gap between the inner drum opening and the outer drum opening is annular, the design of the tapered groove can match the annular gap, so that when the washing water flows circumferentially in the tapered groove, it will not flow into the annular gap but will be smoothly returned to the inner drum for continuous washing of the laundry.

[0035] In the optional technical solution of the protruding structure of the door of the laundry treating apparatus, the bottom surface of the tapered groove is a circular arc surface.

[0036] In the above technical solution, the water flow can smoothly return from the bottom to the opening, which helps to ensure the stability and continuity of the water flow and improves the flow efficiency.

[0037] In the optional technical solution of the protruding structure of the door of the laundry treating apparatus, the opening angle of the tapered groove is in the range of 140° to 170°, and / or the ratio of the diameter of the opening of the tapered groove to the diameter of the opening of the inner drum is in the range of 55% to 85%.

[0038] In the above technical solution, the opening angle of the opening is set to 140°, so that the opening of the tapered groove is not too small, and most of the water flow can enter the tapered groove, thereby providing a larger flow guiding range and ensuring that the water flow can be effectively guided into the inner cylinder. When the opening angle is 170°, the opening is wider and can accommodate more water flow, and in the case of a large water flow, the water flow can be guided into the inner cylinder to ensure that the washing water does not overflow into the annular gap. The ratio of the diameter of the opening of the tapered groove to the diameter of the inner cylinder port is set to 55%, which effectively matches the size of the inner cylinder port, ensures that most of the water flow can flow into the tapered groove, and leaves space for the side wall of the protruding structure to seal with the door seal and be installed with the door body. When the ratio of the diameter of the opening of the tapered groove to the diameter of the inner cylinder port is set to 85%, the amount of washing water entering the tapered groove can be further increased, and the loss of washing water can be further reduced.

[0039] In another aspect, the application also provides a door of a laundry treating apparatus, characterized in that the door comprises a door body and the protruding structure according to any one of the above embodiments.

[0040] In the above technical solution, when the door is applied to the laundry treating apparatus, most of the washing water in the inner cylinder first contacts the end face during the washing process. When the washing water reaches the end face, the flow guiding structure of the end face re-directs the washing water into the inner cylinder without leaking into the gap, thereby greatly reducing the phenomenon of water loss during the washing process of the laundry treating apparatus, and thereby improving the washing effect.

[0041] In another aspect, the application also provides a laundry treating apparatus, comprising an outer cylinder and an inner cylinder, the inner cylinder being rotatably arranged inside the outer cylinder, and an annular gap being formed between an inner cylinder port of the inner cylinder and an outer cylinder port of the outer cylinder; the laundry treating apparatus further comprises the door described above.

[0042] In the above technical solution, when the door is applied to the laundry treating apparatus, most of the washing water in the inner cylinder first contacts the end face of the protruding structure of the door during the washing process. When the washing water reaches the end face, the flow guiding structure of the end face re-directs the washing water into the inner cylinder without leaking into the gap, thereby greatly reducing the phenomenon of water loss during the washing process of the laundry treating apparatus, and thereby improving the washing effect.

[0043] In the above technical solution, the laundry treating apparatus further comprises a shielding structure for shielding the gap.

[0044] In the above technical solution, the shielding structure cooperates with the special structure of the door, most of the washing water flowing to the end surface of the protruding structure of the door is redirected into the inner tub, and a small amount of washing water flowing to the gap is shielded by the shielding structure and can return to the inner tub again, thereby greatly reducing the waste of washing water and further improving the washing effect.

[0045] In the optional technical solution of the above laundry treating apparatus, the laundry treating apparatus further comprises a door seal, the door seal comprises a door seal body and the shielding structure formed on the door seal body, the door seal body forms a seal with the protruding structure and the outer tub, and the shielding structure is located inside the gap.

[0046] In the above technical solution, in combination with the flexible characteristics of the door seal, when the inner tub jumps and contacts the shielding structure, the door seal can be bent or deformed, thereby absorbing the impact caused by the inner tub jumping through deformation, so that the inner tub opening and the shielding structure can maintain good contact even when the inner tub is running at high speed, the distance between the shielding structure and the inner tub opening can be made smaller, and the possibility of washing water flowing out of the gap is reduced. By locating the shielding structure inside the gap, external interference can be minimized, for example, the shielding structure is not directly exposed to the surface of the laundry that may collide frequently during the washing process, reducing the deformation of the shielding structure caused by the collision, thereby ensuring its long-lasting shielding effect and functional stability. In addition, the shielding structure located inside the gap makes the connection between the shielding structure and the door seal body more convenient and reliable.

[0047] In the optional technical solution of the above laundry treating apparatus, the gap is towards the annular radial center thereof, and the shielding structure comprises a first water blocking ring connected with the door seal body, the first water blocking ring is arranged to shield the gap in the radial direction.

[0048] In the above technical solution, since the gap is towards the annular radial center thereof, most of the washing water needs to flow from the radial direction to the gap to leak out, in this case, the first water blocking ring of the present application is arranged to shield the gap in the radial direction, effectively preventing the possibility of water flow from the radial direction into the inside of the gap, especially for the upper gap, the effect is more obvious, thereby further reducing the waste of washing water.

[0049] In the optional technical solution of the above laundry treating apparatus, the shielding structure further comprises a second water blocking ring, the second water blocking ring is arranged on one side of the first water blocking ring close to the inner tub opening, and the second water blocking ring, the first water blocking ring and the door seal body form an annular groove.

[0050] In the above technical solution, the washing water entering the inner side of the gap first flows into the annular groove, wherein the washing water flowing upwards first enters the upper annular groove from the gap, and under the blocking of the annular groove, the washing water changes the flow path and flows to the gap, thereby returning to the inner drum to participate in washing. The washing water flowing downwards enters the lower annular groove from the gap, and under the blocking of the annular groove, the amount of washing water entering the gap between the inner drum and the outer drum can be reduced, thereby avoiding dirt in the gap between the inner drum and the outer drum.

[0051] In the optional technical solution of the above laundry treatment device, the inner drum is a closed inner drum.

[0052] In the above technical solution, the waste of water can be reduced while avoiding the possibility of dirt in the gap between the inner drum and the outer drum entering the inner drum and directly contacting the laundry, thereby improving the washing effect of the laundry.

DETAILED DESCRIPTION

[0064] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship of "upper", "lower" and the like are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present application. The "upper" and "lower" of the present application refer to the upper and lower parts of the laundry treating apparatus in the use state with the height direction as the reference. "Front" refers to the direction close to the door 1 with the horizontal direction of the laundry treating apparatus as the reference, and "rear" refers to the direction close to the back of the laundry treating apparatus with the horizontal direction of the laundry treating apparatus as the reference. In addition, the annular described in the present application is not intended to be limited to a circular ring, but can also be a torus or a polygonal ring, etc.

[0065] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, etc. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0066] Example one: CN202410649864X, figures 1 to 4;

[0067] The present application provides a laundry treating apparatus, which can be a drum washing machine, a drum washing and drying integrated machine, a sock washing machine, etc. The laundry treating apparatus includes a door 1, a cabinet 6, and a drum assembly including an outer drum 3, an inner drum 2, and a door seal 5. The door 1 is pivotally connected to the cabinet 6 at a laundry loading port to open and close the laundry loading port. The outer drum 3 is provided in the cabinet 6, and the inner drum 2 is rotatably provided inside the outer drum 3. The inner drum 2 can be a closed inner drum 2 such that the inner drum 2 is isolated from the outer drum 3 during washing, i.e., the inner drum 2 has no water-permeable hole to allow water to pass through, so as to prevent dirt possibly present at a gap 4 between the inner drum 2 and the outer drum 3 from entering the inner drum 2 to directly contact laundry during washing. It should be noted that, although this is the case, the inner drum 2 can still have an opening to mount a structure capable of being sealed during washing, such as a drainage structure designed to be closed during washing and opened during drainage, so that the inner drum 2 is closed during washing, and washing water can be drained to the outside of the inner drum 2 through the drainage structure during drainage. The drainage structure can be a centrifugal valve, etc. Of course, the above description is not limiting, and the laundry treating apparatus can also be provided without the drainage structure, as long as the inner drum 2 is closed during washing to prevent water in the inner drum 2 from flowing to the outside through the inner wall of the inner drum 2.

[0068] The door 1 of the laundry treating apparatus can include a door body 11 (not shown in the drawings) and a protruding structure 12 protruding from the door body 11. The protruding structure 12 can be recessed. The door body 11 can include a first annular frame and a second annular frame. The open end of the protruding structure 12 is clamped between the first annular frame and the second annular frame. The first annular frame and the second annular frame can be fixedly connected by clamping, bolting, etc., so that the protruding structure 12 is fixed to the door body 11. It should be noted that, although the above is described by way of example of the first annular frame and the second annular frame, this is not intended to limit the scope of protection of the present application. As long as the protruding structure 12 can be fixed to the door body 11, the specific form can be adjusted, for example, a single annular frame can be used instead of two separate frames. The frame can have an inner recessed slot for accommodating the open end of the protruding structure 12, and then be fixed by bolting, clamping, or other mechanical means. These adjustments do not deviate from the principles of the present application and are within the scope of protection of the present application. The protruding structure 12 can be a transparent window made of glass or plastic, or can be an opaque protruding structure 12, etc.

[0069] Referring to FIG. 2 or FIG. 4, the door seal 5 of the present application includes a door seal body 51 for forming a seal with the protruding structure 12 and the outer tub 3 to prevent water from leaking out of the area between the outer tub 3 and the door 1, and a shielding structure 52 formed on the door seal body 51 for shielding the gap 4 between the inner tub port 21 and the outer tub port 31 of the laundry treating apparatus. The door seal 5 of the present application can be integrally formed, and can be made of a flexible material such as silicone, rubber, polyurethane, or an elastomer composite.

[0070] Since the shielding structure 52 formed on the door seal body 51 shields the gap 4 between the inner tub port 21 and the outer tub port 31, the shielding structure 52 can shield the front end of the gap between the inner tub 2 and the outer tub 3 that causes water to leak, so that most of the water does not enter the gap between the inner tub 2 and the outer tub 3, thereby significantly reducing the possibility of a decrease in the amount of washing water in the inner tub 2, and thus improving the washing effect. On the basis of this, in combination with the flexible characteristics of the door seal 5, when the inner tub 2 jumps and contacts the shielding structure 52, the door seal 5 can bend or deform, thereby absorbing the impact caused by the jumping of the inner tub 2 through the deformation, so that the inner tub port 21 and the shielding structure 52 can maintain good contact even when the inner tub 2 is operated at a high speed, and thus the distance between the shielding structure 52 and the inner tub port 21 can be made smaller, thereby reducing the possibility of the washing water flowing out of the gap 4.

[0071] As one possible embodiment, the door seal body 51 includes a main body portion 511, a first connecting portion 512 connected to the main body portion 511, and a second connecting portion 513 for forming a seal with the protruding structure 12, so that the protruding structure 12 penetrates into the annular door seal 5 and forms a seal with the second connecting portion 513 when the door 1 is closed. After the first connecting portion 512 wraps the outer tub port 31, the first connecting portion 512 can be tightly clamped on the outer side wall of the outer tub port 31 by a clamping device such as a clamp, or the first connecting portion 512 can be directly bonded to the outer side wall of the outer tub port 31, etc., to ensure firm connection and prevent leakage. Since the first connecting portion 512 wraps the outer tub port 31, not only can the door seal 5 be tightly connected to the outer tub 3, but also the first connecting portion 512 can extend from the outer tub port 31 into the gap 4, so that the extended portion can shield part of the gap 4, and by adjusting the thickness of the first connecting portion 512 or the tightness of the wrapping of the outer tub port 31, the distance between the first connecting portion 512 and the inner tub port 21 can be made smaller, thereby further reducing the possibility of the washing water flowing out of the gap 4.

[0072] As a possible implementation, the shielding structure 52 is located inside the gap 4. Since the shielding structure 52 is located inside the gap 4, the external interference can be minimized, such that it is not directly exposed to the surface of the laundry which may form frequent collision during the washing process, and the deformation of the shielding structure 52 caused by the collision can be reduced, thereby ensuring the persistent shielding effect and functional stability of the shielding structure 52. In addition, the shielding structure 52 located inside the gap 4 also makes the connection between the shielding structure 52 and the door seal body 51 more convenient and reliable.

[0073] As a possible implementation, the gap 4 is towards the radial center of the annular gap 4, that is, the gap 4 formed between the inner drum opening 21 and the outer drum opening 31 is an annular gap 4, and the opening of the annular gap 4 is towards the radial center of the annular gap 4. Possibly, referring to FIG. 2, the shielding structure 52 of the present application includes a first water blocking ring 521 located inside the gap 4, the first water blocking ring 521 is connected with the part of the first connecting portion 512 located inside the outer drum opening 31, and the first water blocking ring 521 is arranged to be able to radially shield the gap 4.

[0074] Since the gap 4 is towards the radial center of the annular gap 4, most of the washing water needs to flow radially to the gap 4 before it can leak out, in this case, the first water blocking ring 521 of the present application is arranged to be able to radially shield the gap 4, effectively preventing the possibility of water flow from the radial into the inside of the gap 4, especially for the upper gap 4, the effect is more obvious, thereby further reducing the waste of washing water.

[0075] As a possible implementation, referring to FIG. 4, the shielding structure 52 further includes a second water blocking ring 522, the second water blocking ring 522 is arranged on the side of the first water blocking ring 521 close to the inner drum opening 21, and the second water blocking ring 522, the first water blocking ring 521 and the part of the first connecting portion 512 located inside the outer drum opening 31 form an annular groove 523, so that the opening of the annular groove 523 is towards the gap 4.

[0076] The above arrangement makes the washing water entering the inside of the gap 4 flow into the annular groove 523 first, wherein the upward flowing washing water first enters the upper annular groove 523 from the gap 4, and changes the flow path under the blocking of the annular groove 523 to flow towards the gap 4, thereby returning to the inner drum 2 to participate in the washing. The downward flowing washing water enters the lower annular groove 523 from the gap 4, and the amount of washing water entering the gap 4 between the inner drum 2 and the outer drum 3 can be reduced under the blocking of the annular groove 523, thereby avoiding the dirt at the gap 4 between the inner drum 2 and the outer drum 3.

[0077] Further, the second water blocking ring 522 is spaced apart from the inner drum opening 21 by a distance d from the end of the first water blocking ring 521, so that the inner drum 2 can rotate efficiently. Possibly, the distance d is in the range of 2mm-4mm. For example, the distance is 3mm. The above distance can make the gap 4 smaller while ensuring that the inner drum 2 rotates efficiently and does not affect the washing operation, thereby greatly reducing the risk of washing water leakage. In addition, in the case where the first connecting portion 512 extends into the inside of the outer drum opening 31 to block part of the gap 4, the second water blocking ring 522 is spaced apart from the inner drum opening 21 by the above smaller distance from the end of the first water blocking ring 521, which can further block, thereby greatly reducing the amount of washing water leakage.

[0078] As a possible implementation, the door seal body 51 of the present application further comprises a third connecting portion 514 formed on the main body portion 511, and the third connecting portion 514 forms a seal with the cabinet 6. For example, an annular protrusion is formed on the cabinet 6, and the third connecting portion 514 is wrapped around the annular protrusion. After the third connecting portion 514 is wrapped around the annular protrusion, the third connecting portion 514 can be tightly clamped on the annular protrusion by a clamping device (such as a clamp, etc.), or the third connecting portion 514 can be wrapped around the annular protrusion by a strap, etc., to ensure firm connection. In addition, the main body portion 511 can be configured in a pleated or folded structure, so as to improve the deformation degree of the door seal 5 and provide cushioning for vibration, etc.

[0079] As a possible implementation, referring to FIGS. 1 and 3, the protruding structure 12 of the door 1 of the present application is closer to the inside of the inner drum 2 than the gap 4, i.e., the protruding structure 12 is closer to one side of the bottom wall in the axial direction of the inner drum 2 than the gap 4. Thus, the protruding structure 12 can block a part of the washing water to flow back to the inside of the inner drum 2, so as to participate in the washing process again. The washing water flowing to the gap 4 and not blocked by the protruding structure 12 will be blocked by the blocking structure 52, reducing the amount of washing water entering the inside of the gap 4. Therefore, the above arrangement can greatly reduce the waste of washing water, thereby improving the washing effect. On the other hand, the protruding structure 12 can also push the laundry back to the inside of the inner drum 2 to participate in the washing, thereby improving the washing effect.

[0080] In summary, the laundry treatment apparatus of the present application can reduce water waste and reduce the occurrence of the situation that the water becomes less and less while avoiding the situation that the dirt possibly existing in the gap between the inner drum and the outer drum of the laundry treatment apparatus directly contacts the laundry, thereby improving the washing effect of the laundry.

[0081] It should be noted that the above possible implementations can be used in combination, thereby combining new implementations to be applicable to more specific application scenarios.

[0082] In addition, it also needs to be explained that the above-mentioned embodiments are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust the above-mentioned structure without deviating from the principles of the present application, so that the present application can be applied to more specific application scenarios.

[0083] For example, as an alternative embodiment, although the present application is introduced by taking the first connecting part 512 wrapping the outer cylinder port 31 as an example, this is not intended to limit the protection scope of the present application. For example, the first connecting part 512 is directly sealed and connected to the inner side or the outer side of the outer cylinder port 31, etc., as long as it can form a seal with the outer cylinder 3. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0084] For example, as an alternative embodiment, the convex structure 12 can be omitted, in which case the second connecting part 513 can form a seal between the door body 11. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0085] For example, as an alternative embodiment, the third connecting part 514 can be omitted, and the main body part 511 of the door seal body 51 can be directly fixed to the cabinet 6 by adhesion, screw connection, etc. Even the door seal body 51 can not be connected to the cabinet 6, etc. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0086] Example two: CN2024108103692, Figures 5 and 6;

[0087] The present application provides a laundry treating apparatus, which can be a drum washing machine, a drum washing and drying machine, a sock washing machine, etc. The laundry treating apparatus includes a door 1, a cabinet 6, an outer drum 3, an inner drum 2, and a door seal 5. The door 1 is pivotally connected to the cabinet 6 at a laundry loading port to open and close the laundry loading port. The outer drum 3 is fixedly provided in the cabinet 6. The inner drum 2 is rotatably connected to the inner side of the outer drum 3. The connection manner can be any existing or future connection manner. The door seal 5 forms a seal with the outer drum 3 and forms a seal with the door 1 when the door 1 is closed. The inner drum 2 can be a closed inner drum 2, so that the inner drum 2 is isolated from the outer drum 3 during washing. That is, the inner drum 2 does not have a water-permeable hole to allow water to flow through. This avoids dirty water in the gap between the inner drum 2 and the outer drum 3 from entering the inner drum 2 and directly contacting the laundry. It should be noted that the inner drum 2 can still have an opening to install a structure that can be sealed during washing, such as a drainage structure. The drainage structure is designed to be closed during washing and opened during drainage, so that the inner drum 2 is closed during washing, and washing water can be drained to the outside of the inner drum 2 through the drainage structure during drainage. The drainage structure can be a centrifugal valve, etc. Of course, the above description is not limiting. As long as the laundry treating apparatus can prevent water in the inner drum 2 from flowing to the outside through the inner wall of the inner drum 2 during washing, the laundry treating apparatus can also not have a drainage structure. The door seal 5 of the present application can be integrally formed. The material can be a flexible material such as silicone, rubber, polyurethane, or an elastomer composite.

[0088] The door 1 of the laundry treating apparatus can include a door body 11 and a protruding structure 12 protruding from the door body 11, the protruding structure 12 of the door 1 being protruded into the cabinet from the laundry loading port after the door 1 is closed. The protruding structure 12 can be in a groove shape, and the door body 11 can include a first annular frame and a second annular frame, the open end of the protruding structure 12 being interposed between the first annular frame and the second annular frame, and the first annular frame and the second annular frame can be fixedly connected by a clamping, a bolt connection, or the like, so as to fix the protruding structure 12 to the door body 11. It should be noted that, although the above is described by taking the first annular frame and the second annular frame as an example, this is not intended to limit the protection scope of the present application, as long as the protruding structure 12 can be fixed to the door body 11, the specific form can be adjusted, for example, a single annular frame is used instead of two separate frames, the frame can have an inner recessed slot for accommodating the open end of the protruding structure 12, and then it is fixed by a bolt, clamping or other mechanical means, and the like, these adjustments do not deviate from the principle of the present application, and are within the protection scope of the present application. The protruding structure 12 can be constructed as a transparent window of glass or plastic material, of course, it can also be constructed as a non-transparent protruding structure 12, and the like.

[0089] The end surface 122 of the protruding structure 12 of the door 1 of the present application faces the inner side of the inner drum 2, it can be understood that the end surface 122 refers to the side of the protruding structure 12 opposite to the door body 11 in the axial direction of the inner drum 2. The end surface 122 is closer to the inner side of the inner drum 2 than the gap 4 between the inner drum port 21 and the outer drum port 31, so that the protruding structure 12 is protruded into the inner drum port 21, in addition, the end surface 122 is formed with a flow guide structure for guiding water into the inner drum 2.

[0090] Since the end surface 122 is closer to the inner side of the inner drum 2 than the gap 4, during the washing process, most of the washing water in the inner drum 2 will first contact the end surface 122, after the washing water reaches the end surface 122, the flow guide structure of the end surface 122 will guide the washing water into the inner drum 2 again, without leaking into the gap 4, thereby greatly reducing the phenomenon of water reduction during the washing process of the laundry treating apparatus, thereby improving the washing effect.

[0091] As a possible implementation, the flow guide structure is designed as a tapered groove 121. In this way, when the washing water reaches the end face 122, it enters the tapered groove 121. After reaching the bottom of the tapered groove 121, the water continues to flow and flows out of the slot 1212 of the tapered groove 121 along the side wall of the tapered groove 121, as shown by the arrow direction in FIG. 1. Due to the inclined shape of the side wall of the tapered groove 121, the direction of the water flow is effectively controlled, so that the water flow flows towards the inner side of the inner cylinder 2 away from the gap 4, and the washing water is re-introduced into the inner cylinder 2 to participate in the washing, thereby improving the introduction efficiency of the water flow. In addition, since the gap 4 between the inner cylinder port 21 and the outer cylinder port 31 is annular, the design of the tapered groove 121 can match the annular gap 4, so that when the washing water flows circumferentially in the tapered groove 121, it will not flow into the annular gap 4, but will be smoothly returned to the inner cylinder 2 to continue to participate in the washing of the clothes.

[0092] It should be noted that although the flow guide structure of the present application is described by taking the tapered groove 121 as an example, this is not intended to limit the protection scope of the present application. As long as the flow guide structure can guide the water into the inner cylinder 2, the specific form can be adjusted, for example, the flow guide structure is only provided as an inclined surface inclined towards the inner side of the inner cylinder 2, or the flow guide structure is designed as a bent flow guide pipe, the flow guide pipe is arranged in the protruding structure 12, the end face 122 is provided with an inlet and an outlet, the inlet is located above the outlet, the two ends of the flow guide pipe are connected with the inlet and the outlet respectively, and the area of the inlet is larger than that of the outlet. Similarly, it can also guide part of the washing water back to the inner side of the inner cylinder 2. These adjustments do not deviate from the principles of the present application and are within the protection scope of the present application.

[0093] As a possible implementation, the bottom surface 1211 of the tapered groove 121 is designed as a circular arc surface. In this way, the water flow can smoothly return to the slot 1212 from the bottom, which helps to ensure the stability and continuity of the water flow and improves the flow guide efficiency.

[0094] As a possible implementation, the opening angle a of the tapered groove 121 is in the range of 140°-170°. Preferably, it is 168°. If the opening angle is set to 140°, the slot 1212 of the tapered groove 121 will not be too small, so that most of the water flow can enter the tapered groove 121, thereby providing a larger flow guide range and ensuring that the water flow can be effectively guided into the inner cylinder 2. If the opening angle is 170°, the slot 1212 is wider and can accommodate more water flow. In the case of a large water flow, it can also ensure that the water flow is guided into the inner cylinder 2, so that the washing water will not overflow into the annular gap 4.

[0095] As a possible implementation, the ratio of the diameter b of the notch 1212 of the tapered groove 121 to the caliber c of the inner drum mouth 21 is in the range of 55% to 85%, such as 70%. By setting the ratio of the diameter b of the notch 1212 of the tapered groove 121 to the caliber c of the inner drum mouth 21 to 55%, the size of the inner drum mouth 21 can be effectively matched, ensuring that most of the water flow can flow into the tapered groove 121, and leaving space for the side wall of the protruding structure 12 to form a seal with the door seal 5 and to be installed between the door body 11. By setting the ratio of the diameter b of the notch 1212 of the tapered groove 121 to the caliber c of the inner drum mouth 21 to 85%, the amount of washing water entering the tapered groove 121 can be further increased, further reducing the loss of washing water.

[0096] As a possible implementation, as shown in FIG. 2, the door seal 5 includes a door seal body 51 and a shielding structure 52 formed on the door seal body 51, the shielding structure 52 is used to shield the gap 4. The door seal body 51 includes a main body part 511, a first connecting part 512 connected to the main body part 511, and a second connecting part 513, the first connecting part 512 wraps the outer drum mouth 31, and the second connecting part 513 is used to form a seal with the protruding structure 12, so that when the door 1 is closed, the protruding structure 12 penetrates into the annular door seal 5 and forms a seal between the second connecting part 513. After the first connecting part 512 wraps the outer drum mouth 31, the first connecting part 512 can be tightly clamped on the outer side wall of the outer drum mouth 31 by a clamping device (such as a clamp, etc.), or the first connecting part 512 is directly bonded on the outer side wall of the outer drum mouth 31, etc., to ensure firm connection and prevent leakage. Since the first connecting part 512 wraps the outer drum mouth 31, not only can the door seal 5 be tightly connected to the outer drum 3, but also the first connecting part 512 can extend from the outer drum mouth 31 into the gap 4, so that the extending part can shield part of the gap 4. By adjusting the thickness of the first connecting part 512 or the tightness of wrapping the outer drum mouth 31, the distance between the first connecting part 512 and the inner drum mouth 21 can be made smaller, thereby further reducing the possibility of washing water flowing out from the gap 4.

[0097] The shielding structure 52 can shield the front end of the gap between the inner drum 2 and the outer drum 3, which causes water leakage, and shield the washing water flowing to the gap 4 without being guided by the protruding structure 12, so as to obviously reduce the possibility of the reduction of the amount of washing water in the inner drum 2, and further improve the washing effect. On this basis, combined with the flexible characteristics of the door seal 5, when the inner drum 2 jumps and contacts the shielding structure 52, the door seal 5 can be bent or deformed, thereby absorbing the impact caused by the jumping of the inner drum 2 through deformation, so as to ensure that the inner drum port 21 and the shielding structure 52 can maintain good contact even when the inner drum 2 is in high-speed operation and jumping, so that the distance between the shielding structure 52 and the inner drum port 21 can be smaller, thereby reducing the possibility of washing water flowing out from the gap 4.

[0098] As a possible implementation, the shielding structure 52 of the present application is located inside the gap 4. Since the shielding structure 52 is located inside the gap 4, external interference can be minimized, such as making it not directly exposed to the surface of the clothes that may form frequent collisions during washing, reducing the deformation of the shielding structure 52 caused by collisions, thereby ensuring its persistent shielding effect and functional stability. In addition, the shielding structure 52 located inside the gap 4 also makes the connection between it and the door seal body 51 more convenient and reliable.

[0099] As a possible implementation, the gap 4 is towards the radial center of its annular shape, that is, the gap 4 formed between the inner drum port 21 and the outer drum port 31 is an annular gap 4, and the opening of the annular gap 4 is towards the radial center of the annular gap 4. Possibly, the shielding structure 52 of the present application includes a first water blocking ring 521 located inside the gap 4, the first water blocking ring 521 is connected with the part of the first connecting portion 512 located inside the outer drum port 31, and the first water blocking ring 521 is arranged to be able to shield the gap 4 in the radial direction.

[0100] Since the gap 4 is towards the radial center of its annular shape, most of the washing water needs to flow radially to the gap 4 before it can leak out, in this case, the first water blocking ring 521 of the present application is arranged to be able to shield the gap 4 in the radial direction, effectively preventing the possibility of water flow from the radial direction into the inside of the gap 4, especially for the upper gap 4, the effect is more obvious, thereby further reducing the waste of washing water.

[0101] As a possible implementation, the shielding structure 52 further includes a second water blocking ring 522, the second water blocking ring 522 is arranged on the side of the first water blocking ring 521 close to the inner drum port 21, and the second water blocking ring 522, the first water blocking ring 521 and the part of the first connecting portion 512 located inside the outer drum port 31 form an annular groove 523, so that the opening of the annular groove 523 is towards the gap 4.

[0102] The above arrangement allows the washing water entering the gap 4 to flow into the annular groove 523 first, wherein the washing water flowing upwards enters the upper annular groove 523 from the gap 4, and changes the flow path under the blockage of the annular groove 523 to flow towards the gap 4, so as to return to the inner drum 2 to participate in the washing. The washing water flowing downwards enters the lower annular groove 523 from the gap 4, and can reduce the amount of washing water entering the gap 4 between the inner drum 2 and the outer drum 3 under the blockage of the annular groove 523, so as to avoid dirt at the gap 4 between the inner drum 2 and the outer drum 3.

[0103] Further, the second water blocking ring 522 is spaced apart from the end of the first water blocking ring 521 and the inner drum opening 21 by a distance d, so that the inner drum 2 can rotate efficiently. Possibly, the distance d is in the range of 2mm-4mm. For example, the distance is 3mm. The above distance can make the gap 4 smaller under the premise of ensuring the efficient rotation of the inner drum 2 and not affecting the washing, so as to greatly reduce the risk of washing water leakage. In addition, in the case that the part of the first connecting part 512 extending into the inner side of the outer drum opening 31 blocks part of the gap 4, the second water blocking ring 522 is spaced apart from the end of the first water blocking ring 521 and the inner drum opening 21 by the above smaller distance, which can further block, so as to greatly reduce the amount of washing water leakage.

[0104] As a possible implementation, the door seal body 51 of the present application further comprises a third connecting part 514 formed on the main body part 511, and the third connecting part 514 forms a seal with the cabinet 6. For example, an annular protrusion is formed on the cabinet 6, and the third connecting part 514 is wrapped on the annular protrusion. After the third connecting part 514 is wrapped on the annular protrusion, the third connecting part 514 can be tightly clamped on the annular protrusion by a clamping device (such as a clamp, etc.), or the third connecting part 514 can be wrapped on the annular protrusion by a strap, etc., to ensure firm connection. In addition, the main body part 511 can be in a pleated or bent structure, so as to improve the deformation degree of the door seal 5 and provide cushioning for vibration, etc.

[0105] In summary, the laundry treating apparatus of the present application can reduce water waste and reduce the occurrence of the situation that the more the washing, the less the water, so as to improve the washing effect of the laundry, while avoiding the possibility that the dirt in the gap 4 between the inner drum 2 and the outer drum 3 directly contacts the laundry.

[0106] It should be noted that the above possible implementation modes can be used in combination, so as to combine new implementation modes to be applicable to more specific application scenarios.

[0107] In addition, it also needs to be explained that the above-mentioned embodiments are only used to illustrate the principles of the present application, and are not intended to limit the protection scope of the present application. Those skilled in the art can adjust the above-mentioned structure without deviating from the principles of the present application, so that the present application can be applied to more specific application scenarios.

[0108] For example, as an alternative embodiment, although the present application is introduced by taking the first connecting part 512 wrapping the outer cylinder port 31 as an example, this is not intended to limit the protection scope of the present application. For example, the first connecting part 512 is directly sealed and connected to the inner side or outer side of the outer cylinder port 31, etc., as long as it can form a seal with the outer cylinder 3, these adjustments do not deviate from the principles of the present application, and are within the protection scope of the present application.

[0109] For example, as an alternative embodiment, the third connecting part 514 can be omitted, and the main body part 511 of the door seal body 51 can be directly fixed on the cabinet 6 by adhesion, screw connection, etc. Even the door seal body 51 can not be connected with the cabinet 6, etc. These adjustments do not deviate from the principles of the present application, and are within the protection scope of the present application.

[0110] For example, as an alternative embodiment, although the shielding structure 52 of the present application is introduced by taking part of the door seal 5, this is not intended to limit the protection scope of the present application, as long as the shielding structure 52 can shield the gap 4, its specific setting mode can be adjusted, for example, the shielding structure 52 can be replaced by an annular outer cylinder connecting piece arranged on the outer cylinder port 31 and extending to the inner side of the inner cylinder 2 through the inner cylinder port 21, etc. The annular outer cylinder connecting piece can shield the gap 4 from the radial direction. These adjustments do not deviate from the principles of the present application, and are within the protection scope of the present application.

[0111] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments.
