Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment technology, and specifically provides a clothing processing device. Background Technology

[0002] In the construction system of modern drum washing machines, the door seal is an indispensable sealing component between the front panel of the casing and the outer drum, and its performance directly affects the waterproof reliability of the washing machine. When the door is closed, the door seal, with its own elastic deformation characteristics, tightly fits the observation window on the door, forming a waterproof barrier, thereby effectively preventing water from seeping out from the gaps in the door during the washing process.

[0003] In existing technologies, door seals are mostly made of rubber because rubber has good elasticity and sealing performance, and can maintain a stable sealing effect during long-term use. However, the inherent characteristics of rubber also bring significant drawbacks. Its surface texture is relatively hard, and its coefficient of friction is high, resulting in a high coefficient of friction between the rubber and clothing. During the washing cycle of a washing machine, the clothes tumble and beat inside the drum as it rotates, frequently coming into contact with and rubbing against the door seal.

[0004] Furthermore, when users handle clothes daily, the adhesion and friction between the clothes and the door seal, along with the dragging motion, subject the clothes to significant friction. Prolonged friction can easily lead to pilling and snagging on the clothes, and in severe cases, even damage the fabric, shortening the lifespan of the garments and reducing user satisfaction and experience.

[0005] Accordingly, there is a need in the field for a new garment processing device to solve the problems of uneven distribution of tangled garments and wear in existing garment processing devices. Summary of the Invention

[0006] The present invention aims to solve the above-mentioned technical problems, namely, the problems of uneven distribution of tangled clothes and wear in existing clothing processing equipment.

[0007] The present invention provides a garment processing device, the garment processing device including an outer cylinder, a door seal and an anti-friction ring, the outer cylinder having an outer cylinder opening, the door seal including an edge connecting portion that wraps around the edge of the outer cylinder opening, and the anti-friction ring being disposed on the edge connecting portion.

[0008] In the optional technical solution of the above-mentioned garment processing equipment, the anti-friction ring includes a first extension portion extending radially, a second extension portion extending radially, and an annular body extending axially. The first extension portion and the second extension portion are connected through the annular body. The first extension portion, the annular body, and the second extension portion surround to form an installation groove, and the edge connecting portion is located in the installation groove.

[0009] In the optional technical solution of the above-mentioned garment processing equipment, the edge connecting part has a radially protruding protrusion, the protrusion is disposed in the mounting groove, and the edge connecting part forms a first groove and a second groove on both sides of the protrusion, the first extension is accommodated in the first groove, and the second extension is accommodated in the second groove.

[0010] In the optional technical solutions of the above-mentioned clothing processing equipment, the depth of the first groove is the same as the thickness of the first extension.

[0011] In the optional technical solution of the above-mentioned clothing processing equipment, the depth of the second groove is the same as the thickness of the second extension.

[0012] In the optional technical solution of the above-mentioned garment processing equipment, the garment processing equipment further includes an inner cylinder, which is rotatably disposed inside the outer cylinder. The front wall of the inner cylinder is provided with an inner cylinder opening, and the diameter of the anti-friction ring is equal to the diameter of the inner cylinder opening.

[0013] In the optional technical solutions of the above-mentioned clothing processing equipment, the diameter of the front opening of the door seal is larger than the diameter of the inner cylinder opening.

[0014] In the optional technical solutions of the above-mentioned clothing processing equipment, the front opening and the inner drum opening are coaxially arranged.

[0015] In the optional technical solutions of the above-mentioned clothing processing equipment, one of the door seal and the outer cylinder is formed with a protrusion, and the other is formed with a matching groove, and the protrusion is embedded in the groove.

[0016] In the optional technical solutions of the above-mentioned clothing processing equipment, the door seal includes, in sequence along the axial direction, a first annular segment, a telescopic segment, and a second annular segment. The first annular segment forms a front opening, and the second annular segment is connected to the outer cylinder. The diameter of the first annular segment gradually decreases from the front opening toward the outer cylinder.

[0017] Those skilled in the art will understand that the garment processing device of the present invention includes an outer cylinder, a door seal, and an anti-friction ring. The outer cylinder is provided with an outer cylinder opening, the door seal includes an edge connecting portion that wraps around the edge of the outer cylinder opening, and the anti-friction ring is disposed on the edge connecting portion.

[0018] The opening of the outer tube is the primary area where clothing comes into contact with the door seal. Since the door seal includes an edge connector that wraps around the edge of the outer tube opening, and an anti-friction ring is located at this edge connector, when clothing reaches the outer tube opening area, it first contacts the surface of the anti-friction ring, rather than directly contacting the edge connector of the door seal. Because the anti-friction ring has a low coefficient of friction, it reduces friction, effectively preventing problems such as pilling, snagging, and damage to clothing caused by friction. On the other hand, when clothing is thrown towards the outer tube opening at high speed, it will first impact or rub against the anti-friction ring. At this time, the edge connector of the door seal and the connected door seal elastomer can provide effective cushioning through their own deformation, thereby reducing the instantaneous impact force of the clothing on the anti-friction ring and preventing it from loosening, deforming, or detaching from its mounting position due to collision.

[0019] Furthermore, the applicant's research also found that placing the anti-friction ring at the edge connection optimizes the movement trajectory of the clothes. When the garment processing equipment is running, the clothes, upon contact with the anti-friction ring, can tumble and tumble more smoothly, allowing for full contact with the detergent during washing and improving cleaning effectiveness. In the spin-drying stage, the clothes are also more evenly distributed, reducing equipment vibration and noise caused by misaligned clothing, further enhancing the user experience.

[0028] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0029] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] like Figure 1 and Figure 2 As shown, in order to solve the problems of uneven distribution and wear of clothing in existing clothing processing equipment, the clothing processing equipment of the present invention includes an outer cylinder 1, a door seal 3 and an anti-friction ring 2. The outer cylinder 1 is provided with an outer cylinder opening 11, the door seal 3 includes an edge connecting part 34 that wraps around the edge of the outer cylinder opening, and the anti-friction ring 2 is provided on the edge connecting part 34.

[0031] The advantages of the above-described arrangement are as follows: The outer tube opening 11 is the primary area where the clothing comes into contact with the door seal 3. Since the door seal 3 includes an edge connecting portion 34 that wraps around the edge of the outer tube opening, and the anti-friction ring 2 is located on the edge connecting portion 34, when the clothing reaches the area of ​​the outer tube opening 11, it first contacts the surface of the anti-friction ring 2, rather than directly contacting the edge connecting portion 34 of the door seal 3. Due to the low coefficient of friction of the anti-friction ring 2, friction is reduced, effectively preventing problems such as pilling, snagging, and damage to the clothing caused by friction. On the other hand, when the clothing is thrown towards the outer tube opening 11 during high-speed operation, it will first impact or rub against the anti-friction ring 2. At this time, the edge connecting portion 34 of the door seal 3 and the elastic body of the door seal 3 connected to it can provide effective cushioning through their own deformation, thereby reducing the instantaneous impact force of the clothing on the anti-friction ring 2 and preventing it from loosening, deforming, or falling off the mounting position due to collision.

[0032] Furthermore, the applicant's research also found that the anti-friction ring 2, located at the edge connection 34, optimizes the movement trajectory of the clothes. During operation, when the clothes come into contact with the anti-friction ring 2, they can tumble and beat more smoothly, allowing for full contact with the detergent during washing and improving the cleaning effect. In the spin-drying stage, the clothes are also more evenly distributed, reducing equipment vibration and noise caused by eccentric clothing, further enhancing the user experience.

[0033] It is understood that the edge of the outer cylinder opening can be the end face of the outer cylinder opening 11, facing the axis of the outer cylinder opening 11, and / or the side face of the outer cylinder opening edge, facing forward or backward. Various embodiments exist for the edge connecting portion 34 to wrap around the edge of the outer cylinder opening. For example, the edge connecting portion 34 can be provided with a receiving groove, in which the edge of the outer cylinder opening is disposed, thereby achieving complete wrapping of the edge of the outer cylinder opening edge by the edge connecting portion 34. Alternatively, the cross-section of the edge connecting portion 34 can be a straight plane, covering only the end face of the outer cylinder opening edge. Or, the cross-section of the edge connecting portion 34 can be L-shaped, simultaneously covering the end face and one side face of the outer cylinder opening edge; all of these are within the scope of protection of this invention. When the cross-section of the edge connecting portion 34 is a straight plane or L-shaped, the edge connecting portion 34 can be connected to the edge of the outer cylinder opening by means of adhesion, snap-fit, or screwing.

[0034] The anti-friction ring 2 is made of wear-resistant and smooth metal or non-metal material. When the anti-friction ring 2 is made of non-metal material, it can be integrally molded from wear-resistant polymer through injection molding process. For example, polyoxymethylene (POM), nylon (PA66), ultra-high molecular weight polyethylene (UHMWPE) or polytetrafluoroethylene (PTFE) can be selected.

[0035] In one possible implementation, the anti-friction ring 2 includes a radially extending first extension 22, a radially extending second extension 23, and an axially extending annular body 21. The first extension 22 and the second extension 23 are connected by the annular body 21. The first extension 22, the annular body 21, and the second extension 23 form a mounting groove, and an edge connecting portion 34 is located in the mounting groove 24. Specifically, a corresponding portion of the edge connecting portion 34 is embedded in the mounting groove 24, and the thickness of the edge connecting portion 34 is adapted to the axial width of the mounting groove 24 so that its end face abuts against the annular body 21. The first extension 22 and the second extension 23 clamp and limit the edge connecting portion 34 from the outside and inside sides, respectively.

[0036] The above-mentioned arrangement not only ensures the stable installation of the anti-friction ring 2, but also increases the coverage area of ​​the door seal 3 at the outer drum opening 11 of the edge connection part 34. This allows the clothes to come into contact with the anti-friction ring 2 on a larger area when they reach the edge of the outer drum opening 11 during washing and spin-drying, further preventing damage to the clothes due to friction.

[0037] In one possible implementation, the edge connecting portion 34 has a radially protruding protrusion 341, which is disposed in the mounting groove 24. A first groove 342 and a second groove 343 are formed on both sides of the protrusion 341. A first extension 22 is accommodated in the first groove 342, and a second extension 23 is accommodated in the second groove 343. Both the first groove 342 and the second groove 343 communicate with the end face of the edge connecting portion 34. That is, the cross-section of the edge connecting portion 34 has a structure similar to an inverted "U," and the anti-friction ring 2 forms a structure similar to a "U." Through this complementary interlocking design, the anti-friction ring 2 and the edge connecting portion 34 form a mutually engaging and fitting assembly structure, achieving a stable fit between the two. It is understandable that when the cross-section of the edge connection portion 34 is an "inverted convex" structure, if it has a mounting groove 24, the mounting groove 24 is provided at the top of the "inverted convex" structure so as to accommodate the edge of the outer cylinder opening 11.

[0038] As one possible implementation, the depth of the first groove 342 (i.e., the dimension along the axial direction of the outer cylinder 1) is the same as the thickness of the first extension 22. This arrangement allows the outer surface of the first extension 22 to be coplanar and flush with the outer surface of the first groove 342 of the edge connection portion 34, avoiding snagging, pulling, or localized wear caused by edge protrusions or depressions.

[0039] In one possible implementation, the depth of the second groove 343 (i.e., the dimension along the axial direction of the outer cylinder 1) is the same as the thickness of the second extension 23. This arrangement allows the outer surface of the second extension 23 to be coplanar and flush with the outer surface of the second groove 343 of the edge connection portion 34, avoiding snagging, pulling, or localized wear caused by edge protrusions or depressions.

[0040] The garment processing equipment of the present invention can be a drum washing machine, a drum washer-dryer combo, etc. The garment processing equipment includes a housing, within which is an outer drum 1 for holding water. An inner drum 4, covered with perforated holes, is rotatably disposed within the outer drum 1 and is used to hold garments. The output shaft of a drive mechanism passes through the outer drum 1 and connects to the inner drum 4 to drive the inner drum 4 to rotate. The drive mechanism can be a motor, or a combination of a motor and a transmission mechanism, etc. The transmission mechanism can be a pulley or a gear set, etc.

[0041] The front panel of the casing is provided with a clothing loading port, and the inner drum 4 is provided with an inner drum opening 41. The clothing loading port, the outer drum opening 11 and the inner drum opening 41 are coaxially arranged to form a through clothing loading channel for users to pick up and put in clothing.

[0042] The front panel of the casing is hinged to the door, and a transparent observation window is embedded in the middle of the door, allowing the user to easily monitor the operation of the inner drum 4 in real time. A rubber door seal 3 is installed between the outer drum 1 and the front panel. When the door is closed, the observation window extends into the clothing inlet, and the observation window presses against the door seal 3 to form a sealing structure. It should be noted that although the above description uses an observation window as an example, it is not restrictive. As long as the door has a raised portion that extends into the clothing inlet when the door is closed, the specific form of the adjustment will not deviate from the principle of the present invention. For example, the observation window can be replaced with a raised portion made of a non-transparent material, etc.

[0043] The inner diameter of the first extension 22 can be equal to the inner diameter of the second extension 23, and the outer diameter of the first extension 22 is preferably larger than that of the second extension 23. The first extension 22 serves as a connecting plane, and its larger area improves installation stability. The first extension 22 and the second extension 23 of the anti-friction ring 2 adopt a stepped height difference design, wherein the longitudinal dimension of the first extension 22 is larger than that of the second extension 23 by a certain value. This allows the first extension 22 to form a larger connecting plane, with an increased surface area compared to the second extension 23, providing a more stable support foundation for installation and enhancing the overall structural rigidity of the anti-friction ring 2. Its bending strength is higher, effectively preventing deformation and displacement caused by long-term stress.

[0044] Optionally, the anti-friction ring 2 of the present invention is integrally formed, that is, the above-mentioned annular body 21, the first extension 22 and the second extension 23 are integrally formed.

[0045] As one possible implementation, the diameter of the anti-friction ring 2 is equal to the diameter of the inner drum opening 41. This arrangement eliminates the height difference between the annular body 21 and the inner drum opening 41, allowing clothes to smoothly contact the area of ​​the annular body 21 during the rotation of the inner drum 4, reducing the problem of clothes tangling due to gap jamming.

[0046] In one possible implementation, one of the door seal 3 and the outer cylinder 1 is formed with an annular protrusion, and the other is formed with a matching annular groove. The protrusion is embedded in the groove to achieve the connection between the door seal 3 and the outer cylinder 1.

[0047] The door seal 3 and the outer cylinder 1 adopt a mortise and tenon joint connection structure. One of the contact surfaces forms a protrusion, and the other has a corresponding matching groove. The precise fitting of the convex and concave structure achieves a glue-free connection.

[0048] Taking a specific structure as an example, the rear end of the door seal 3 has a door seal groove 331 and a door seal protrusion 332. The outer cylinder 1 has an outer cylinder protrusion 13 that matches the door seal groove 331. The outer cylinder protrusion 13 is embedded in the door seal groove 331. The outer cylinder 1 has an outer cylinder groove 12 that matches the door seal protrusion 332. The door seal protrusion 332 is embedded in the outer cylinder groove 12 to achieve the connection between the door seal and the outer cylinder 1.

[0049] The rear end of the door seal adopts a double convex and double concave composite structure. Its outer surface is provided with a door seal groove 331 and a door seal protrusion 332. The corresponding position of the outer cylinder 1 is stamped with a complementary interlocking structure. The outer cylinder protrusion 13 is embedded in the door seal groove 331, and at the same time, the outer cylinder groove 12 precisely engages with the door seal protrusion 332, forming an interlocking interlocking design.

[0050] In one possible implementation, the door seal 3 includes a first annular segment 31, a telescopic segment 32, and a second annular segment 33 coaxially arranged. When the first annular segment 31 is pressed by the viewing window, the telescopic segment 32 contracts; the telescopic segment 32 can also be referred to as a pleated segment. An edge connecting portion 34, a door seal groove 331, and a door seal protrusion 332 are formed in the second annular segment 33. The first annular segment 31 is provided with a front opening 311. Optionally, the door seal 3 is integrally formed, that is, the first annular segment 31, the telescopic segment 32, and the second annular segment 33 are integrally formed.

[0051] The diameter of the opening 311 at the front of the door seal is larger than the diameter of the opening 41 of the inner drum, and the diameter of the front opening 311 is also larger than the diameter of the anti-friction ring 2. Increasing the diameter of the front opening 311 of the door seal makes it easier for users to take out clothes and avoids friction between the front of the door seal and the clothes. Possibly, the first annular segment 31 adopts a flared structure design, that is, the diameter of the first annular segment 31 gradually decreases along the front opening 311 towards the outer drum 1. Its front opening 311 is larger than the diameter of the inner drum opening 41. Through this differential size design, when the door is open, the front of the door seal 3 forms an outwardly expanding trumpet-shaped transition area, effectively widening the space range of the clothes entering and exiting the machine. This structural design has significant advantages: First, the flared opening moves the contact area between the clothes and the door seal 3 to the direction of the inner drum 4, increasing the distance between the clothes taking out the path and the front edge of the door seal 3, which can reduce the probability of front friction contact. Secondly, the larger opening size significantly reduces the difficulty for users to take out and put in clothes, especially for large items such as heavy coats and blankets, improving the efficiency of taking out and putting in clothes.

[0052] As one possible implementation, the front opening 311 of the door seal and the inner cylinder opening 41 are coaxially arranged.

[0053] The coaxial structure ensures that the contact surfaces of the door seal 3, the machine door observation window, and the inner cylinder opening 41 are evenly stressed, avoiding excessive local compression or sealing failure caused by eccentricity. The regular cylindrical channel reduces path deviation when clothes enter and exit, reducing the risk of wear and tear caused by abrasion. The standardized coaxial design at both ends reduces the difficulty of production and assembly. The door seal 3 can be installed at any rotation angle without affecting sealing and performance, improving assembly efficiency and compatibility with various models of machine doors and outer cylinder structures, enhancing product versatility.

[0054] As one possible implementation, a sealing tongue is provided on the inner side of the front end of the door seal 3, that is, on the first annular segment 31, to close the gap between the door seal 3 and the observation window.

[0055] In terms of sealing structure design, the inner side of the front end of the door seal 3 is provided with an elastic sealing tongue. When the machine door is closed, the observation window squeezes the sealing tongue to cause it to undergo elastic deformation. The sealing tongue fits tightly against the surface of the observation window to form a sealing barrier.

[0056] As described in the first paragraph of this section, the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0057] For example, as an alternative implementation, the specific structure of the anti-friction ring 2 is not fixed. For instance, the anti-friction ring 2 may only include the annular body 21, omitting the first extension 22 and the second extension 23. In this case, the anti-friction ring 2 may only cover the end face of the edge connecting portion 34. Alternatively, the anti-friction ring 2 may only include the first extension 22 and the annular body 21, omitting the second extension 23. Or, the anti-friction ring 2 may only include the second extension 23 and the annular body 21, omitting the first extension 22. In this case, the anti-friction ring 2 may only cover the end face and side face of the edge connecting portion 34. Those skilled in the art can customize the specific structure of the anti-friction ring 2 according to actual needs, as long as it can prevent the edge connecting portion from rubbing against clothing. These modifications do not deviate from the principles of the present invention and therefore fall within the protection scope of the present invention.

[0058] For example, as an alternative implementation, the diameter of the front opening 311 of the first annular segment 31 may be less than or equal to the diameter of the inner cylinder opening 41. The first annular segment 31 may also be a straight cylinder with a constant diameter in the axial direction.

[0059] For example, as an alternative implementation, the diameter of the anti-friction ring 2 is not equal to the diameter of the inner cylinder opening 41.

[0060] For example, as an alternative implementation, the door seal 3 and the outer cylinder 1 can be connected by bolts, snap-fit ​​connections, etc. These adjustments do not deviate from the principles of the present invention and are all within the scope of protection of the present invention.

[0061] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
