By arranging the guide surface, the lifting ribs roll along with the inner drum and push clothes in the front-back direction at the same time, after the clothes are pushed to the other end, due to the fact that the lifting surface which is higher than the guide surface in the height direction is arranged at the other end, the clothes can continue to be lifted at the other end, and therefore the clothes can fall from the higher height; therefore, the washing effect is improved.

Description

Technical Field

[0001] This utility model relates to clothing processing equipment, specifically to a clothing processing equipment with lifting ribs. Background Technology

[0002] As drum-type garment processing equipment becomes increasingly accepted, the demands on its washing capabilities are also constantly rising. Drum-type garment processing equipment mainly utilizes lifting ribs to continuously lift and tumble the clothes to achieve the purpose of washing. The lifting height of the clothes by the lifting ribs determines the tumbling force of the clothes, which has a significant impact on the cleanliness of the clothes.

[0003] However, in existing technologies, the lifting height of the lifting ribs for clothes is often less than expected. For example, CN200910136045.0 discloses a water-repelling blade with a spray structure. This blade is axially positioned on the inner surface of the drum of a drum washing machine, with its bottom surface connected to the inner surface of the drum. The blade has a centrally symmetrical structure formed around the geometric center of its top. A concave water-collecting groove is provided on each of the blade's different transverse sides, with the two grooves located near one end of the blade's longitudinal structure. A protrusion is formed on the top of the blade corresponding to the water-collecting groove to expand the space inside the groove. The protruding portion of this protrusion slopes gently towards the other end of the blade's longitudinal structure. Due to the longitudinal slope, the clothes move from high to low along the slope during the lifting process. When the clothes reach the lowest point, they fall and cannot be lifted further. Therefore, it is difficult for the clothes to effectively reach the highest point of the drum, resulting in poor washing performance and inadequate eccentricity correction.

[0004] Therefore, it is necessary to improve the existing garment processing equipment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a garment processing device, including a roller. The roller has an inner cylinder and lifting ribs disposed on the side wall of the inner cylinder. The lifting ribs include a guide surface and a lifting surface. The guide surface has a first side disposed on the side wall and a second side protruding from the end of the first side in a direction away from the side wall. At least a portion of the second side is spaced from the first side at a distance that gradually decreases from one end of the lifting rib to the other end. The lifting surface has the second side and a third side protruding further away from the side wall than the second side.

[0006] By setting a guide surface whose distance from the side wall gradually decreases from one end to the other, the lifting ribs push the clothes in the front-to-back direction while the inner drum rolls. After the clothes are pushed to the other end, the lifting surface at the other end, which is higher than the guide surface in the height direction, allows the clothes to continue to be lifted by the lifting surface, so as to drop the clothes from a higher height, thereby achieving a better tumbling effect and improving the washing effect.

[0007] Optionally, the lifting surface is formed into a concave shape.

[0008] This design increases the contact area between the clothing and the lifting surface, and at least part of the clothing is contained within the recessed shape. Both of these aspects are beneficial for the lifting surface to move and lift the clothing.

[0009] Optionally, the guide surface is a convex surface or a plane.

[0010] During the lifting process, the clothing moves along the guide surface to a lower point and then falls onto the lifting surface to continue lifting. This not only achieves the function of pushing the clothing back and forth but also lifts the clothing to a higher position. Designing the guide surface as a convex or flat surface makes it easier for the clothing to be pushed from one end to the other along the surface of the guide surface.

[0011] Optionally, the lifting rib also has an end face defined by a fourth side disposed on the sidewall, a fifth side connecting the fourth side away from the first side to the third side, and a sixth side extending from the third side, wherein the junction of the end face and the lifting surface is formed to be furthest from the sidewall.

[0012] This configuration ensures that when the clothing is guided from a higher position to a lower position on the guide surface, the lower position corresponds to the vicinity of the highest point of the lifting surface. As a result, a better lifting effect is achieved under the influence of the lifting surface.

[0013] Optionally, water spray holes are provided on the guide surface and / or the lifting surface.

[0014] This setting can further improve the washing effect.

[0015] Optionally, the lifting surface is formed such that the distance between the second side and the first side in the guide surface gradually decreases while the distance between the third side and the second side gradually increases.

[0016] In this case, the lifting surface also achieves a guiding effect from one end to the other of the lifting rib. While being lifted by the lifting surface, the garment can be pushed from the edge of the inner tube towards the center in the front-back direction, thereby achieving the eccentricity correction of the garment.

[0017] Optionally, two guide surfaces are symmetrically arranged with respect to the central axis of the lifting rib, and two lifting surfaces are symmetrically arranged with respect to the central axis of the lifting rib, with the two lifting surfaces sharing a common edge.

[0018] This design allows the garment to be pushed forward and backward and its height to be fully increased in each direction of rotation as the inner drum rotates clockwise and counterclockwise.

[0019] In addition, since the two guide surfaces and two lifting surfaces are symmetrically arranged, the forward and backward movement and height lifting of the clothes are more uniform, thereby improving the washing effect.

[0020] In addition, since the two lifting surfaces share a third side, the lifting ribs can achieve the forward and backward movement and sufficient height increase of the garment in both clockwise and counterclockwise rotation directions without taking up too much space in the inner drum.

[0021] Optionally, an end face is provided at one end and at the other end, and the distance between the junction of each end face and the lifting surface and the side wall is the same.

[0022] This design ensures that the clothes on both sides of the lifting ribs maintain a consistent lifting height, resulting in a more even washing effect.

[0023] Optionally, the average tilt angle of the guide surface relative to the sidewall is greater than the average tilt angle of the lifting surface relative to the sidewall.

[0024] This design makes the average tilt angle of the lifting surface gentler, which is more conducive to the full contact and retention of clothing with the lifting surface, and facilitates the movement of clothing.

[0025] Optionally, the garment processing equipment is: a drum washing machine, a drum steam iron, a drum dry cleaning machine, a drum mite removal machine, a drum dryer, or a drum shoe washing machine. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0032] First Implementation Method

[0033] like Figure 1 As shown, this embodiment provides a garment processing device, including a roller 100, the roller having an inner cylinder 200 and lifting ribs 300 disposed on the side wall 210 of the inner cylinder 200.

[0034] Combination Figure 2 and Figure 3 The lifting rib 300 includes a guide surface 310 and a lifting surface 320. The guide surface 310 has a first side 10 disposed on the side wall 210 and a second side 20 protruding from the end of the first side 10 in a direction away from the side wall 210. The distance between the second side 20 and the first side 10 is formed in such a way that it gradually decreases from one end of the lifting rib 300 toward the other end. The lifting surface 320 has the second side 20 and a third side 30 protruding in a direction further away from the side wall 210 than the second side 20.

[0035] The working principle of the 300 lifting rib is explained in detail below.

[0036] The lifting rib 300 is generally strip-shaped. For ease of explanation, the bottom surface of the lifting rib 300 is taken as the horizontal plane, and the direction is defined and explained based on the natural placement of the lifting rib 300 in a horizontal position. The "one end" and "other end" mentioned above specifically refer to one end and the other end of the lifting rib 300 along its length (i.e., the front-to-back direction of the inner cylinder 200). The first side 10 forms the edge of the bottom surface of the lifting rib 300, and the second side 20 protrudes from the end of the first side 10 in a direction away from the side wall 210 (i.e., the height direction when the lifting rib 300 is horizontal). That is, the second side 20 protrudes along the height direction away from the side wall 210. Simultaneously, since the distance between the second side 20 and the first side 10 gradually decreases from one end of the lifting rib 300 towards the other end, the guide surface 310 also forms a shape that decreases in height and width from one end to the other, thus achieving a shape that decreases in height from one end towards the other. The other end (the front-back direction of the inner drum 200) pushes the clothes; when the clothes are pushed to the other end, the clothes at least partially transition / move to the lifting surface 320 that connects with the guide surface 310. Since the lifting surface 320 is defined by the second side 20 and the third side 30 that protrudes further away from the side wall 210 than the second side 20, at least at the other end of the lifting rib 300, the lifting surface 320 is higher than the guide surface 310 in the height direction. This design allows the clothes pushed to the other end of the lifting rib 300 to continue to be lifted upward with the rolling of the inner drum under the action of the lifting surface 320. While realizing the front-back movement of the clothes, the lifting height of the clothes is guaranteed, thus improving the washing effect.

[0037] Optionally, the lifting surface 320 can also be configured such that each part is higher than the guide surface 310; or, at the position corresponding to the relatively low point (e.g., the end) of the guide surface 310, it is higher than the guide surface 310, and at other positions it is not lower than the guide surface 310; the height of the lifting surface 320 is defined by the relative positional relationship between the third side 30 and the side wall 210.

[0038] In this embodiment, by setting a guide surface 310 whose distance from the side wall 210 gradually decreases from one end to the other, the lifting rib 300 can push the clothes in the front-back direction while the inner drum 200 rolls. After the clothes are pushed to the other end, the lifting surface 320, which is higher than the guide surface 310 in the height direction at the other end, can continue to be lifted at the other end by the lifting surface 320, so as to drop the clothes from a higher height, thereby achieving a better tumbling effect and improving the washing effect.

[0039] Optionally, the lifting surface 320 is formed into a concave shape. The specific range and area of ​​the concave shape can be appropriately set according to the size of the garment handling equipment or other requirements. Preferably, the concave shape is formed in the area of ​​the lifting surface 320 located at the end of the lifting rib 300. This arrangement increases the contact area between the garment and the lifting surface 320, and at least a portion of the garment is contained within the concave shape. Both of these design features are beneficial for the lifting surface 320 to drive and lift the garment.

[0040] Optionally, the guide surface 310 can be convex or flat. This configuration makes it easier for clothing to be pushed from one end to the other along the surface of the guide surface 310.

[0041] Optionally, water spray holes 301 are provided on the guide surface 310 and / or the lifting surface 320, which can further improve the washing effect.

[0042] Optionally, the lifting surface 320 is formed such that the distance between the second side 20 and the first side 10 in the guide surface 310 gradually decreases while the distance between the third side 30 and the second side 20 gradually increases. In this case, the lifting surface 320 also achieves the guiding effect from one end to the other end of the lifting rib 300. While being lifted by the lifting surface 320, the garment can be pushed from the edge of the inner tube 200 towards the center in the front-back direction, thereby achieving the eccentricity correction of the garment.

[0043] More specifically, as a preferred option, the lifting surface 320 can be configured such that the middle area along the front-back direction of the inner tube 200 is concave. This configuration makes it easier for the clothes to be pushed to the middle area of ​​the lifting surface 320, making it difficult for them to continue to be pushed to one end of the lifting rib 300, thus further ensuring the effect of clothes eccentricity correction.

[0044] It should be noted that, since the inner drum 200 of the drum-type garment handling equipment may rotate clockwise, counterclockwise, or alternately clockwise and counterclockwise, the guide surface 310 and lifting surface 320 of the lifting rib 300 are arranged facing one side of the rotation direction of the inner drum 200 or one of the rotation directions, in order to achieve the aforementioned technical effect of driving the garment. In this embodiment, the shape of the other side of the lifting rib 300 is not limited; it can be a plane or curved surface formed by a certain distance between the side wall 210 and the first side 10 along the width direction of the lifting rib 300 and connecting with the third side 30.

[0045] Second Implementation Method

[0046] The main difference between this embodiment and the garment processing device shown in the first embodiment is that, Figure 4As shown, the guide surface 310 of the lifting rib 300 is arranged symmetrically with respect to the central axis of the lifting rib 300 in two ways, and the lifting surface 320 is arranged symmetrically with respect to the central axis of the lifting rib 300 in two ways. The two lifting surfaces 320 have a common side, namely the third side 30.

[0047] This design allows the garment to be pushed forward and backward and its height to be fully increased in each direction of rotation as the inner drum rotates clockwise and counterclockwise alternately.

[0048] In addition, since the two guide surfaces 310 and the two lifting surfaces 320 are centrally symmetrically arranged, the forward and backward movement and height lifting of the clothes are more uniform, thereby improving the washing effect.

[0049] In addition, since the two lifting surfaces 320 share the third side 30, the lifting ribs 300 can achieve the forward and backward movement and sufficient height increase of the clothes in both clockwise and counterclockwise rotation directions without occupying too much space in the inner tube.

[0050] Optionally, the projection of the third side 30 on the horizontal plane is tilted at a certain angle relative to the central axis of the lifting rib 300, so that it simultaneously satisfies the relative positional relationship with the second side 20 on both sides of the central axis. This setting achieves the expected function of the structure while making full use of the space, reducing the overall size of the lifting rib 300, reducing manufacturing costs and the space occupied by the inner cylinder 200.

[0051] Optionally, the lifting rib 300 also has an end face 330, which is defined by a fourth side 40 disposed on the side wall 210, a fifth side 50 connecting to the third side 30 from the side of the fourth side 40 away from the first side 10, and a sixth side 60 extending from the third side 30. The junction of the end face 330 and the lifting surface 320 is formed to be furthest away from the side wall 210.

[0052] This configuration ensures that when the clothing is guided from a higher position to a lower position on the guide surface 310, the lower position corresponds to the vicinity of the highest point on the lifting surface 320, achieving a better lifting effect.

[0053] In addition, since the junction of the end face 330 and the lifting face 320 is formed to be the furthest from the side wall 210, its height relative to the middle area of ​​the lifting face 320 is higher, which also realizes the guidance of the garment along the end face 330 to the middle area of ​​the lifting face 320, and realizes the eccentricity correction of the garment.

[0054] Optionally, such as Figure 5 As shown, an end face 330 is provided at one end and the other end of the lifting rib 300, and the junction of each end face 330 and the lifting surface 320 is at the same distance from the side wall 210.

[0055] This configuration ensures that the heights of the two high points formed at the junction of each end face 330 and the lifting face 320 remain consistent, and that the lifting height of the clothes on both sides of the lifting rib 300 remains consistent, resulting in a more uniform washing effect.

[0056] Optionally, the average tilt angle of the guide surface 310 relative to the side wall 210 is greater than the average tilt angle of the lifting surface 320 relative to the side wall 210.

[0057] This design makes the average tilt angle of the lifting surface 320 gentler, which is more conducive to the full contact and retention of the clothing with the lifting surface 320, and facilitates the movement of the clothing.

[0058] Optionally, the clothing processing equipment provided in this embodiment can be a drum washing machine, which can achieve better washing effect by setting the lifting ribs 300; it can also be a drum steam iron, drum dry cleaning machine, drum mite removal machine, drum dryer or drum shoe washing machine, etc., which need to achieve better clothing processing effect by lifting and / or pushing the clothes.

[0059] Optionally, the clothing processing device provided in this embodiment is equipped with two or more lifting ribs 300, and the two or more lifting ribs 300 are symmetrically distributed on the side wall 210 with respect to the axial center of the inner drum 200. This arrangement not only enhances the washing effect, but also makes the washing of clothes more uniform.

[0060] The technical solution of this utility model has now been described in conjunction with the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to the specific embodiments described above. Without departing from the principles of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions resulting from these changes or substitutions will all fall within the protection scope of this utility model.
