Description

Technical Field

[0001] This invention belongs to the field of clothing cleaning, specifically, it relates to an inner drum of a clothing processing device and the clothing processing device itself. Background Technology

[0002] With social development and technological progress, and the continuous improvement of people's living standards, laundry processing equipment is rapidly becoming popular in various households, bringing convenience to users' laundry. For top-loading impeller laundry processing equipment, large capacity and high dehydration rate are its main development trends.

[0003] The laundry washing machine uses an upward-facing inner tub to tumble the water and clothes, causing them to collide and rub against the inner tub, thus achieving the washing purpose. To improve the washing efficiency, the inner tub usually has different shaped moldings to increase the friction between the inner tub and the clothes. At the same time, the moldings also strengthen the structural strength of the inner tub and prevent it from deforming over time.

[0004] Currently, some garment processing equipment has circular moldings on the inner drum. The surface of the circular moldings is a smooth curved surface, which can improve the washing effect while reducing the wear and tear on clothes. However, as the clothes move around in the inner drum, they are impacted and rubbed by the uneven surface formed by the moldings. Therefore, the moldings need to be densely distributed in the circumferential direction and have a small horizontal dimension. On the other hand, the moldings need to have a certain length in the vertical direction to strengthen the inner drum and make the unevenness of the moldings in the vertical direction smoother so that water can flow through. However, since the length of the circular moldings in the vertical and horizontal directions is equal, it is difficult for the circular moldings to meet both of the above requirements at the same time, and the actual use effect is unsatisfactory.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an inner tub of a garment processing device and a garment processing device, wherein the pressing structure is composed of an ellipsoidal pressing and a transition pressing, so that the size of the pressing structure can be flexibly adjusted according to actual needs, thereby solving the problem that the existing pressing cannot simultaneously meet the different needs of the inner tub in the circumferential and vertical directions.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: an inner tub of a garment processing device, wherein a molding structure is provided on the inner tub, the molding structure includes an ellipsoidal molding arranged along the long axis of the inner tub; a transition molding disposed between two ellipsoidal moldings, with its two ends respectively transitionally connected to the corresponding ellipsoidal moldings; the ellipsoidal moldings and the transition moldings cooperate to form a continuously extending molding structure.

[0008] Furthermore, the height of the center position of the ellipsoidal molding is less than or equal to the minor axis radius;

[0009] Preferably, the height of the center position of the ellipsoidal molding is less than or equal to half of the minor axis radius.

[0010] Furthermore, the height of the transition molding gradually decreases from both ends to the center;

[0011] Preferably, the center of the transition molding protrudes from the inner wall of the inner barrel.

[0012] Furthermore, multiple rows of molding structures (2) are provided on the inner barrel (1), at least some of the molding structures are arranged in pairs along the circumference of the inner barrel, and the two molding structures in the same group are staggered in the long axis direction.

[0013] Furthermore, the two sides of the ellipsoidal molding face the transition molding of the adjacent molding structure, and the two sides of the transition molding are recessed inward from both ends to the center.

[0014] Preferably, the short axis extension of the ellipsoidal molding passes through the center of the corresponding transition molding;

[0015] More preferably, the length of the major axis of the ellipsoidal molding is equal to the length between the two ends of the transition molding.

[0016] Furthermore, the two sides of each transition molding are smooth arc-shaped edges;

[0017] Preferably, the arc-shaped edge of each transition molding is parallel to the adjacent side edge of the corresponding ellipsoidal molding of the adjacent molding structure.

[0018] Furthermore, the major axis of the ellipsoidal molding is parallel to the axis of the inner barrel.

[0019] Furthermore, the inner barrel body has water passage holes on at least part of the molding structure on both the left and right sides; the water passage holes include the first water passage hole located on both sides of the molding center of each ellipsoidal surface of the molding structure.

[0020] Preferably, at least one second water passage is provided between each of the first water passages, and the second water passage is located close to the transition molding.

[0021] Preferably, a second water passage hole is provided on both sides of the junction between the transition molding and the ellipsoidal molding.

[0022] Furthermore, the inner barrel is divided into alternating first and second regions along the circumferential direction. The molding structure includes a first molding structure, which is staggered and arranged in the first region; and a second molding structure, which is arranged in at least part of the second region. The outer dimensions of the second molding structure are larger than the outer dimensions of the first molding structure located in the first region.

[0023] Preferably, the width of the first region is greater than that of the second region;

[0024] Preferably, the center protrusion height of the second ellipsoidal molding of the second molding structure is greater than the center protrusion height of the first ellipsoidal molding of the first molding structure;

[0027] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the pressing structure is composed of ellipsoidal pressing and transition pressing, so that the pressing structure can be densely arranged in the circumferential direction of the inner tub, increasing the contact area of ​​the inner tub. During the washing process, the inner tub can come into more full contact with the water flow and clothes, thereby enhancing the friction between the inner tub and the clothes.

[0028] Meanwhile, the ellipsoidal molding has a longer extension length in the axial direction of the inner barrel, which makes its surface extend along a gentler curve in the vertical direction, thus improving the structural strength of the inner barrel.

[0029] Furthermore, during the washing process, the clothes move more smoothly in the vertical direction, reducing damage and tangling.

[0030] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0039] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] like Figures 1 to 2 As shown in the embodiment of the present invention, an inner tub 1 of a garment processing device is introduced. The inner tub 1 is provided with a molding structure 2. The molding structure 2 includes an ellipsoidal molding 210 arranged along the long axis of the inner tub 1; and a transition molding 220 disposed between two ellipsoidal moldings 210, with both ends respectively transitionally connected to the corresponding ellipsoidal moldings 210. The ellipsoidal moldings 210 and the transition moldings 220 cooperate to form a continuously extending molding structure 2.

[0041] With the above configuration, the molding structure 2 is composed of an ellipsoidal molding 210 and a transition molding 220, allowing the molding structure 2 to be densely arranged around the inner tub circumference, increasing the contact area of ​​the inner tub 1. During the washing process, the inner tub 1 can make more full contact with the water flow and clothes, thereby enhancing the friction between the inner tub and the clothes. At the same time, the ellipsoidal molding 210 has a longer extension length in the axial direction of the inner tub 1, so that its surface extends along a relatively gentle curve in the vertical direction, improving the structural strength of the inner tub 1. Furthermore, during the washing process, the clothes move more smoothly in the vertical direction, reducing damage and tangling of the clothes.

[0042] In the embodiments of the present invention, the ellipsoid corresponding to the ellipsoidal surface pressing 210 is formed by rotating an ellipse around its major axis by half a revolution.

[0043] In the embodiments of the present invention, the height of the center position of the ellipsoidal molding 210 is less than or equal to the minor axis radius; so that when the inner tub 1 is subjected to external forces such as water flow and clothing, the ellipsoidal molding 210 helps to improve the overall structural strength of the inner tub 1, avoids deformation and damage caused by stress concentration, and ensures the stability of the inner tub 1 during long-term use.

[0044] In embodiments of the present invention, the height of the center position of the ellipsoidal molding 210 is less than or equal to half of the minor axis radius; this makes the ellipsoidal molding 210 relatively flatter, allowing the clothes to come into closer contact with the ellipsoidal molding 210 during washing, increasing friction and helping to remove stains deep in the clothing fibers more effectively.

[0045] In embodiments of the present invention, the height of the transition pressure mold 220 gradually decreases from both ends to the center; this causes a gradient change in the contact pressure and friction between the clothing and the surface of the transition pressure mold 220 when the clothing passes through it, enabling more effective rubbing of the clothing and making it easier to remove stains under varying degrees of compression and friction on the clothing fibers; at the same time, the water flow can form a more complex flow pattern when passing through the transition pressure mold 220 area, making it easier for the water flow to penetrate the clothing fibers, carrying detergent to all parts of the clothing, and also helping to rinse stains off the clothing, thereby improving the overall washing effect.

[0046] In embodiments of the present invention, the surface of the transition molding 220 is a smooth, concave curve from top to bottom; preferably, the curvature of the transition molding 220 gradually decreases from both ends to the center.

[0047] In an embodiment of the present invention, the center of the transition molding 220 protrudes from the inner wall of the inner tub 1, so that even the center of the transition molding 220 with the lowest protrusion height can effectively rub the clothes.

[0048] In an embodiment of the present invention, the major axis diameter of the ellipsoidal molding 210 is greater than or equal to twice its minor axis diameter.

[0049] In an embodiment of the present invention, the length of the major axis of the ellipsoidal molding 210 is less than its major axis diameter; the two sides of the transition molding 220 are flush with the two sides of the ellipsoidal molding 210.

[0050] In an embodiment of the present invention, the two sides of the transition molding 220 are smoothly connected to the two sides of the ellipsoidal molding 210.

[0051] In an embodiment of the present invention, the two ends of the transition molding 220 are smoothly connected to the corresponding ends of the ellipsoidal molding 210.

[0052] In an embodiment of the present invention, multiple rows of molding structures (2) are provided on the inner tub (1). At least some of the molding structures 2 are arranged in pairs along the circumference of the inner tub 1, and the two molding structures 2 in the same group are staggered in the long axis direction. This makes the friction force different when the clothes transition from one molding structure 2 to another because the protrusion height of the molding structure 2 in contact with the clothes is different. This causes the clothes to form a more complex movement trajectory under the action of two different friction forces, and changes in direction and posture will occur. This change makes all parts of the clothes fully rubbed, improving the uniformity and thoroughness of washing.

[0053] In embodiments of the present invention, multiple sets of molding structures 2 are arranged adjacently along the circumferential direction of the inner barrel 1; preferably, the spacing between each set of molding structures 2 is equal to the spacing between two molding structures 2 in the same set.

[0054] In an embodiment of the present invention, the two sides of the ellipsoidal molding 210 are directly opposite the transition molding 220 of the adjacent row of molding structures 2, and the two sides of the transition molding 220 are recessed inward from both ends to the center.

[0055] The above-mentioned settings further enhance the all-round tumbling and rubbing of clothes, thereby improving the washing effect. In addition, by making the two sides of the transition molding 220 concave, it avoids the two sides of the ellipsoidal molding 210 of the adjacent molding structure 2, making the two more compactly placed. At the same time, a flow channel extending vertically is formed between the transition molding 220 and the ellipsoidal molding 210. When the water flows from bottom to top along the flow channel under the action of centrifugal force, it will be affected by the shape of the flow channel and constantly change direction, causing the relative position between the clothes to change continuously, reducing the possibility of them getting tangled, and also preventing the water from flowing excessively upward along the inner tub 1, which would cause water to splash out of the inner tub.

[0056] In an embodiment of the present invention, the minor axis extension of the ellipsoidal molding 210 passes through the center of the corresponding transition molding 220.

[0057] In an embodiment of the present invention, the length of the major axis of the ellipsoidal molding 210 is equal to the length between the two ends of the transition molding 220.

[0058] In an embodiment of the present invention, the length of the major axis of the ellipsoidal molding 210 is equal to its major axis radius.

[0059] In embodiments of the present invention, the two sides of each transition molding 220 are smooth arc-shaped sides; so that the transition molding 220 and the ellipsoidal molding cooperate to form a smooth, meandering flow channel, allowing water to flow smoothly along the flow channel.

[0060] In embodiments of the present invention, the arc-shaped edge of each transition molding 220 is parallel to the adjacent side edge of the corresponding ellipsoidal molding 210 of the adjacent molding structure 2; so as to form an arc-shaped wave flow channel extending in the vertical direction, and the flow channel width at each position is equal, so that it can smoothly guide water and reduce the residual water on the inner barrel 1.

[0061] In one embodiment of the present invention, the major axis of the ellipsoidal molding 210 has a certain angle with the axis of the inner barrel 1, and the molding structure 2 extends spirally along the inner barrel 1; preferably, the angle of inclination of the major axis of the ellipsoidal molding 210 from top to bottom to the circumference is less than 45 degrees; so that the two sides of the molding structure 2 form an integral flow channel extending spirally from top to bottom.

[0062] In another preferred embodiment of the present invention, the major axis of the ellipsoidal molding 210 is parallel to the axial direction of the inner barrel 1.

[0063] With the above settings, the reinforcing mold extends parallel to the axis of the inner tub 1, making the force on the inner tub 1 more uniform during rotation, reducing stress concentration and deformation caused by uneven force, thereby improving the structural stability and durability of the inner tub 1; the major axis of the ellipsoidal mold 210 is parallel to the axis, which can guide the water flow along the axial direction of the inner tub 1, forming a more orderly water flow pattern, improving the utilization rate of detergent and the washing effect.

[0064] In embodiments of the present invention, the inner barrel 1 has water passage holes 110 on at least part of the left and right sides of the molding structure 2; the water passage holes 110 include first water passage holes 111 disposed on both sides of the center of each ellipsoidal molding 210 of the molding structure 2.

[0065] With the above configuration, by setting first water passage holes 111 on both sides of the center of the ellipsoidal molded form 210, water near the center area where the ellipsoidal molded form 210 protrudes the highest can be directly discharged from or flow into the inner tub through the first water passage holes 111. Since the ellipsoidal molded form 210 plays a key role in rubbing and tumbling during the clothing processing, when the clothing moves to the vicinity of the ellipsoidal molded form 210, the water between the clothing and the ellipsoidal molded form 210 can be quickly discharged from the inner tub through the first water passage holes 111. This avoids the formation of a water flow layer between the ellipsoidal molded form 210 and the clothing, which would prevent the clothing from fully contacting the ellipsoidal molded form 210. It also avoids the water flow changing direction near the ellipsoidal molded form 210, causing the clothing to move away from the ellipsoidal molded form 210, thus ensuring that the molded form structure 2 can efficiently clean the clothing.

[0066] In one embodiment of the present invention, each ellipsoidal molded surface 210 of all the molded structures 2 is provided with a first water passage hole 111 on both sides.

[0067] In another embodiment of the present invention, at least one second water passage 112 is provided between each of the first water passage holes 111, and the second water passage holes 112 are provided close to the transition molding 220; by providing multiple second water passage holes 112 between the first water passage holes 111, sufficient water passage area is ensured on the inner tub 1, so that water can smoothly enter and exit the inner tub, and the water can circulate rapidly in the inner tub and the outer tub surrounding it, thereby improving the washing effect.

[0068] In the embodiments of the present invention, at least one of the molding structures 2 in each group of molding structures 2 has water passage holes 110 on both sides; preferably, the molding structures 2 located on the same circumferential side in each group of molding structures 2 have a first water passage hole 111 and a second water passage hole 112 on both sides.

[0069] In this embodiment of the invention, second water passage holes 112 are provided on both sides of the junction between the transition molding 220 and the ellipsoidal molding 210; since the two sides of the ellipsoidal molding 210 gradually contract inward from the center to both ends, when the inner barrel 1 rotates, some water will flow along the edge of the ellipsoidal molding 210 to the junction of the ellipsoidal molding 210 and the transition molding, passing through this location.

[0070] Because the transition molding 220 is a concave arc shape from top to bottom, while the ellipsoidal molding 210 is a convex arc shape from top to bottom.

[0071] In embodiments of the present invention, the first water passage hole 111 and the second water passage hole 112 have the same diameter.

[0072] In an embodiment of the present invention, the water passage 110 includes a third water passage 113 arranged circumferentially along the inner barrel 1, and each third water passage 113 is located above the molding structure 2; preferably, the aperture of the third water passage 113 is larger than the aperture of the first water passage 111, so as to increase the passing area of ​​the third water passage 113, thereby reducing the amount of water flowing upward along the inner wall of the inner barrel 1 and splashing out of the inner barrel from the top opening of the inner barrel.

[0073] In an embodiment of the present invention, the inner barrel 1 is divided into alternating first regions 101 and second regions 102 along the circumferential direction. The molding structure 2 includes a first molding structure 201, which is staggered and arranged in the first region 101; and a second molding structure 202, which is disposed in at least a portion of the second region 102. The outer dimensions of the second molding structure 202 are larger than the outer dimensions of the first molding structure 201 located in the first region 101. Preferably, the width of the first region 101 is larger than that of the second region 102.

[0074] With the above configuration, a densely arranged first pressing structure 201 is provided in the first area 101 of the inner tub 1, which has a larger area, so that the clothes are subjected to more sufficient and diverse mechanical action in the first area 101, and most clothes can be treated more evenly. In addition, by providing a second pressing structure 202 with a larger external size in the relatively long and narrow second area 102 between the first areas 101, some stubborn stains or special parts on the clothes can be treated in a focused manner, so that stains on different parts of the clothes can be effectively removed, and the uniformity of washing clothes can be improved.

[0075] In embodiments of the present invention, the first molding structures 201 are arranged in pairs within the first region 101, and the two first molding structures 201 in the same group are staggered in the long axis direction.

[0076] In embodiments of the present invention, four first regions 101 and four second regions 102 are respectively provided on the inner barrel 1, and a second pressing structure 202 is provided in at least two opposite second regions 102; preferably, the second pressing structure 202 is provided in two opposite second regions 102, and the remaining two opposite second regions 102 are provided with a lint filter device for filtering lint in the water; so as to balance the center of gravity of the inner barrel 1 and prevent the inner barrel from deflecting due to its own center of gravity shift when rotating.

[0077] In an embodiment of the present invention, only one column of second pressing patterns is provided in the second region 102 having the second pressing pattern; preferably, the length of the second ellipsoidal pressing pattern 212 of the second pressing pattern in the minor axis direction is greater than or equal to half the width of the second region 102.

[0078] In embodiments of the present invention, the central protrusion height of the second ellipsoidal molded surface 212 of the second molding structure 202 is greater than the central protrusion height of the first ellipsoidal molded surface 211 of the first molding structure 201; the higher central protrusion height of the second ellipsoidal molded surface 212 enables it to apply greater pressure when in contact with clothing, more effectively breaking the bonding force between stains and clothing fibers, and improving the stain removal effect.

[0079] In an embodiment of the present invention, the center protrusion height of the second transition molded form 222 of the second molding structure 202 is greater than the center protrusion height of the first transition molded form 221 of the first molding structure 201.

[0080] In an embodiment of the present invention, the central protrusion height of the second transition molding 222 of the second molding structure 202 is greater than or equal to the central protrusion height of the first ellipsoidal molding 211 of the first molding structure 201; so that each part of the second molding structure 202 in the vertical direction can apply a pressure to the clothes that is not less than that applied by the first ellipsoidal molding 211, further promoting the rubbing and turning of the clothes and improving the washing effect.

[0081] In embodiments of the present invention, the major axis radius of the second ellipsoidal molding 212 of the second molding structure 202 is greater than or equal to 1.5 times the major axis radius of the first ellipsoidal molding 211 of the first molding structure 201, and less than or equal to 3 times the major axis radius of the first ellipsoidal molding 211; preferably, the major axis radius of the second ellipsoidal molding 212 of the second molding structure 202 is equal to 2 times the major axis radius of the first ellipsoidal molding 211 of the first molding structure 201. During the garment processing, the larger second ellipsoidal molding 212 can better guide the garment to unfold, avoiding tangling and knotting. When the garment passes through the second ellipsoidal molding 212, it will be subjected to a more uniform force, allowing its fibers to unfold more fully, thereby improving the washing effect and making the garment smoother and softer after washing. In the subsequent spin-drying and air-drying process, there will be relatively fewer wrinkles, which helps to reduce the workload of ironing the garment after drying and improves the user experience.

[0082] In an embodiment of the present invention, a garment processing device is also described, which adopts the inner tub 1 of a garment processing device as described above.

[0083] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. The implementation schemes in the above embodiments can be further combined or replaced.
