DETAILED DESCRIPTION

[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] At present, clothes processing equipment such as washing machines usually have lifting ribs on the inner wall of the drum. When the drum rolls, the lifting ribs lift the clothes to make them fall, thereby achieving cleaning.

[0026] For example, in the related art, a washing machine includes a drum and lifting ribs arranged on the inner wall of the drum, the lifting ribs include a top wall, a front wall, a left wall, a rear wall and a right wall, the top wall covers one end of a tubular structure formed by sequentially connecting the front wall, the left wall, the rear wall and the right wall. The outer surfaces of the left wall and the right wall are both smooth curved surfaces, and along the direction from the front wall to the rear wall, the inclination angle of the left wall relative to the top wall gradually decreases, and the inclination angle of the right wall relative to the top wall gradually increases, thereby forming a single-peaked lifting rib. The lifting rib has only one peak structure, and it is not easy to hang on the clothes when lifting them, resulting in poor lifting effect of the lifting rib, which reduces the washing effect of the clothes.

[0027] In order to solve the above technical problems, the present disclosure provides a lifting rib, wherein the lifting rib body includes a first lifting part and a second lifting part arranged side by side, and along the direction from the first end to the second end of the lifting rib body, the top height of the first lifting part gradually decreases, and the top height of the second lifting part gradually increases, thereby forming two peak-shaped structures. With such a design, the lifting rib is easier to hang the clothes and lift them to a higher place, which improves the lifting effect of the lifting rib on the clothes and is more conducive to shaking the clothes, thereby improving the washing effect of the clothes.

[0028] An exemplary embodiment of the present disclosure provides a lifting rib, such as Figure 1 As shown, the lifting rib 1 includes a lifting rib body, and the lifting rib body includes a first lifting part 11 and a second lifting part 12 arranged side by side, and a connecting part 15 connecting the first lifting part 11 and the second lifting part 12. With such a setting form, on the one hand, it plays a role of connecting the first lifting part 11 and the second lifting part 12, and while facilitating the setting of the first lifting part 11 and the second lifting part 12, it improves the stability of the first lifting part 11 and the second lifting part 12 when they are set, thereby improving the reliability of the clothing processing device. On the other hand, by setting the connecting part 15, the friction between the lifting rib 1 and the clothing can also be increased, which can improve the lifting effect of the clothing and the shaking effect of the clothing, thereby improving the washing effect of the clothing.

[0029] The lifting rib body includes a first end and a second end relative to each other. Along the direction from the first end to the second end of the lifting rib body, the top height of the first lifting part 11 gradually decreases, and the top height of the second lifting part 12 gradually increases, thereby forming two peak-shaped structures. In this way, when the drum of the clothing processing device rotates, it is easier for the lifting rib 1 to catch the clothes and lift them to a higher place, which improves the lifting effect of the lifting rib 1 on the clothes and is more conducive to shaking the clothes, thereby further improving the washing effect of the clothes. It should be noted that when the lifting rib 1 is arranged on the inner wall of the drum of the clothing processing device, the end of the first lifting part 11 away from the wall connected to it is the top of the first lifting part 11, and similarly, the end of the second lifting part 12 away from the wall connected to it is the top of the second lifting part 12.

[0030] In addition, the design of the two peak-shaped structures in this embodiment is also conducive to enhancing the turbulence intensity of water when it flows through the lifting ribs 1, thereby increasing the intensity of the water flow on the clothes, thereby improving the cleaning effect on the clothes.

[0031] like Figure 1 and Figure 2As shown, in one embodiment, the first lifting portion 11 includes a first side wall 111, and the second lifting portion 12 includes a second side wall 121, and the first side wall 111 and the second side wall 121 are respectively located on two opposite sides of the lifting rib body. Exemplarily, the first side wall 111 includes a bottom edge 1112 for abutting against the inner wall of the drum and a top edge 1111 opposite to the bottom edge 1112 of the first side wall 111, and the second side wall 121 also includes a bottom edge 1212 for abutting against the inner wall of the drum and a top edge 1211 opposite to the bottom edge 1212 of the second side wall 121. Along the direction from the first end to the second end of the lifting rib body, the top edge 1111 of the first side wall 111 gradually tilts toward the bottom edge 1112 of the first side wall 111. For example, after the top edge 1111 of the first side wall 111 gradually tilts toward the bottom edge 1112 of the first side wall 111, the first side wall 111 may form a trapezoidal structure, or the first side wall 111 may form a triangular structure. Along the direction from the first end to the second end of the lifting rib body, the top edge 1211 of the second side wall 121 gradually tilts toward the bottom edge 1212 away from the second side wall 121. For example, after the top edge 1211 of the second side wall 121 gradually tilts toward the bottom edge 1212 away from the second side wall 121, the second side wall 121 may form a trapezoidal structure, or the second side wall 121 may form a triangular structure. The peak-shaped structure formed by the inclined top edge 1111 of the first side wall 111 and the peak-shaped structure formed by the inclined top edge 1211 of the second side wall 121 are respectively located at the two ends of the lifting rib body. With such a configuration, when the drum of the laundry processing device rotates, the lifting rib 1 is more likely to catch the laundry and lift it to a higher place, which improves the lifting effect of the lifting rib 1 on the laundry and is more conducive to shaking the laundry, thereby further improving the washing effect of the laundry.

[0032] like Figure 1 and Figure 3As shown, in one embodiment, along the direction from the bottom edge 1112 of the first side wall 111 to the top edge 1111 of the first side wall 111, the first side wall 111 is inclined toward the direction close to the second side wall 121. Along the direction from the bottom edge 1212 of the second side wall 121 to the top edge 1211 of the second side wall 121, the second side wall 121 is inclined toward the direction close to the first side wall 111. With such a design, on the one hand, both the first side wall 111 and the second side wall 121 are inclined, which ensures that the lifting effect of the lifting rib 1 on the clothes can be improved, and at the same time, improves the smoothness of the clothes when sliding down from the lifting rib 1 at a high place, and avoids the clothes from being unable to slide down from the lifting rib 1 at a high place, which affects the normal washing of the clothes, thereby effectively improving the washing effect of the clothes. On the other hand, by inclining the first side wall 111 and the second side wall 121, the lifting ribs 1 can ensure that the lifting effect of clothes is improved while improving the smoothness of clothes when sliding down from the lifting ribs 1 at a high place, regardless of whether the drum is rotating in a first direction (the first direction may be, for example, clockwise) or in a second direction opposite to the first direction (the second direction may be, for example, counterclockwise). This further improves the cleaning effect of clothes and enhances the user experience.

[0033] like Figure 1 As shown, in one embodiment, the connecting portion 15 includes a first top wall 13, the first top wall 13 connects the top edge 1111 of the first side wall 111 and the top edge 1211 of the second side wall 121, and the first top wall 13 is twisted following the inclination of the top edge 1111 of the first side wall 111 and the top edge 1211 of the second side wall 121, thereby forming a twisted curved surface. At the same time, at the two ends of the lifting rib body, the twisting directions of the curved surface are different. It can be understood that the first side wall 111 and the second side wall 121 are arranged oppositely, and the peak-shaped structure formed by the first side wall 111 and the peak-shaped structure formed by the second side wall 121 are opposite and located at the two ends of the lifting rib body, thereby causing the twisting directions of the curved surface formed by the first top wall 13 to be opposite. With such a setting form, on the one hand, the friction between the lifting rib body and the clothes is further increased, and when the drum of the clothes processing device rotates, the lifting rib 1 is easier to hang the clothes to lift them to a higher place, which improves the lifting effect of the lifting rib 1 on the clothes, and is more conducive to shaking the clothes, thereby further improving the washing effect of the clothes. On the other hand, the structural form of the lifting rib body can effectively improve the aesthetic appearance of the lifting rib 1, thereby further improving the user experience.

[0034] Continue to refer Figure 1In one embodiment, the first lifting portion 11 further includes a second top wall 112, and the top edge 1111 of the first side wall 111 is connected to the first top wall 13 through the second top wall 112. By providing the second top wall 112, the transition between the top edge 1111 of the first side wall 111 and the first top wall 13 is smoother, and the edges formed by the direct connection between the top edge 1111 of the first side wall 111 and the first top wall 13 are prevented from being too sharp to cause scratches on the clothes, thereby further improving the washing effect on the clothes and improving the reliability of the clothes processing device.

[0035] Similarly, the second lifting portion 12 further includes a third top wall 122, and the top edge 1211 of the second side wall 121 is connected to the first top wall 13 via the third top wall 122. By providing the third top wall 122, the transition between the top edge 1211 of the second side wall 121 and the first top wall 13 is made smoother, and the edges formed by the direct connection between the top edge 1211 of the second side wall 121 and the first top wall 13 are prevented from being too sharp and causing scratches on the clothes, thereby further improving the washing effect on the clothes and improving the reliability of the clothes processing device.

[0036] Continue to refer Figure 1 In one embodiment, a water-passing hole 14 is further provided on the lifting rib body. With such a setting, on the one hand, when the clothing processing device washes the clothing, water can flow from the water-passing hole 14 into the drum, and the water flowing out of the water-passing hole 14 can form a spraying effect, which can increase the rate of wetting the clothing, and improve the washing effect of the clothing while facilitating the washing of the clothing. On the other hand, when the clothing processing device dehydrates the clothing, the water falling off the clothing can flow out from the water-passing hole 14, thereby increasing the rate of dehydrating the clothing and improving the user experience.

[0037] Continue to refer Figure 1 In one embodiment, the water through hole 14 is provided on the second top wall 112, and the second top wall 112 is inclined following the inclination of the top edge 1111 of the first side wall 111. For example, the water through hole 14 is provided on the second top wall 112 at the peak structure formed by the first side wall 111. Since the peak structure formed by the first side wall 111 is closer to the clothes, such a design can improve the spraying effect on the clothes, thereby facilitating the improvement of the washing effect on the clothes.

[0038] Continue to refer Figure 1In another embodiment, the water through hole 14 is provided on the third top wall 122, and the third top wall 122 is inclined following the inclination of the top edge 1211 of the second side wall 121. For example, the water through hole 14 is provided on the third top wall 122 at the peak structure formed by the second side wall 121. Since the peak structure formed by the second side wall 121 is closer to the clothes, such a design can improve the spraying effect on the clothes, thereby facilitating the improvement of the washing effect on the clothes.

[0039] Continue to refer Figure 1 In another embodiment, water through holes 14 are provided on the second top wall 112 and the third top wall 122. Such a setting can further improve the spraying effect on the clothes, thereby effectively improving the washing effect on the clothes.

[0040] like Figure 1 and Figure 4 As shown, in one embodiment, the first lifting part 11 further includes a first end wall 113 disposed at the first end of the lifting rib body, and the second lifting part 12 further includes a second end wall 123 disposed at the second end of the lifting rib body. The first end wall 113, the first side wall 111, the second top wall 112, the first top wall 13, the third top wall 122, the second side wall 121 and the second end wall 123 enclose a hollow cavity. With such a configuration, while effectively improving the structural strength of the lifting rib 1, it is possible to prevent clothes from entering between the first lifting part 11 and the second lifting part 12 to affect the normal washing of clothes, thereby effectively improving the washing effect of clothes. Exemplarily, the connection between the first end wall 113, the first side wall 111, the second top wall 112, the first top wall 13, the third top wall 122, the second side wall 121 and the second end wall 123 is a smoothly transitioned curved surface, so that each connection is prevented from being too sharp to cause scratches on the clothes, thereby further improving the washing effect of the clothes and improving the reliability of the clothes processing device. Exemplarily, the first end wall 113, the first side wall 111, the second top wall 112, the first top wall 13, the third top wall 122, the second side wall 121 and the second end wall 123 are an integrally formed structure. Such a design facilitates the processing of the lifting rib 1 while saving the process of assembling the lifting rib body, thereby effectively improving the assembly effect of the clothing processing equipment.

[0041] The lifting rib 1 also includes at least one connection portion 15 disposed in the hollow cavity. For example, only one connection portion 15 may be disposed in the hollow cavity, or multiple connection portions 15 may be disposed in the hollow cavity. The lifting rib body is disposed on the drum through each connection portion 15, thereby realizing the installation and fixation of the lifting rib 1. For example, the fixing of the lifting rib body can be realized by bonding between the connection portion 15 and the inner wall of the drum, or by clamping the connection portion 15 on the inner wall of the drum to realize the fixing of the lifting rib body, or by fastening the connection portion 15 to the inner wall of the drum by screws, thereby realizing the fixing of the lifting rib body. This embodiment does not make specific restrictions on this. With such a setting form, on the one hand, while improving the convenience of fixing the lifting rib body, it can effectively improve the stability of the lifting rib body when it is disposed in the drum, thereby improving the reliability of the clothing processing device. On the other hand, by arranging each connection portion 15 in the hollow cavity, it can not only reduce the occupation of the internal space of the drum, but also avoid the connection portion 15 from scratching the clothes, thereby further improving the washing effect of the clothes.

[0042] like Figure 4 As shown, in one embodiment, the lifting rib 1 further includes at least one reinforcing rib 16 disposed in the hollow cavity. For example, one reinforcing rib 16 may be disposed in the hollow cavity, or multiple reinforcing ribs 16 may be disposed in the hollow cavity as required. By providing the reinforcing rib 16, the structural strength of the lifting rib 1 can be further improved, thereby improving the reliability of the clothing processing device while effectively improving the lifting effect of the clothing, and preventing the lifting rib 1 from breaking when lifting the clothing, thereby affecting the lifting of the clothing.

[0043] Continue to refer Figure 4 In another embodiment, at least one connection portion 15 and at least one reinforcement rib 16 are provided in the hollow cavity at the same time. Exemplarily, each connection portion 15 and each reinforcement rib 16 can be provided separately, or the connection portion 15 can be provided on the reinforcement rib 16. For example, a plurality of reinforcement ribs 16 are provided in the hollow cavity, and one connection portion 15 is provided on at least one reinforcement rib 16. Exemplarily, the connection portion 15 is provided on only one reinforcement rib 16, or one connection portion 15 is provided on each reinforcement rib 16. Each connection portion 15 is provided at the bottom edge of the reinforcement rib 16 corresponding thereto. It can be understood that when the lifting rib 1 is provided on the inner wall of the drum, the end of the reinforcement rib 16 close to the inner wall of the drum is the bottom edge of the reinforcement rib 16.

[0044] Such a design reduces the distance between the connecting portion 15 and the roller, making the structure of the connecting portion 15 simple and easy to process, while saving the use of materials, thereby helping to reduce production costs.

[0045] like Figure 1As shown, in one embodiment, a friction structure is provided on the surface of the connection part 15, and the friction between the lifting rib 1 and the clothes can be further increased by providing the friction structure, so as to further enhance the lifting effect of the lifting rib 1 on the clothes. At the same time, the turbulence intensity of the water flowing through the lifting rib 1 can be further enhanced, so as to enhance the intensity of the water flow on the clothes, thereby improving the washing effect on the clothes.

[0046] Continue to refer Figure 1 In one embodiment, the friction structure includes a plurality of grooves 131 extending from the first lifting portion 11 to the second lifting portion 12. With such a configuration, on the one hand, the friction structure is simple and easy to process. On the other hand, while increasing the friction between the lifting rib 1 and the clothes, the grooves 131 can also guide the water flow, thereby facilitating the washing of the clothes and improving the washing effect of the clothes.

[0047] Continue to refer Figure 1 In one embodiment, the angle between the groove 131 and the extension direction of the lifting rib 1 is less than 90°. This design ensures that the lifting rib 1 can enhance the lifting effect of the clothes while taking into account the guiding effect of the groove 131 on the water flow, further improving the washing effect of the clothes and improving the user experience.

[0048] In one embodiment, the groove walls of each groove 131 are smooth curved surfaces, which can effectively improve the smoothness of water flowing through the groove 131, thereby improving the guiding effect on the water flow.

[0049] An exemplary embodiment of the present disclosure provides a clothes processing device, which may be, for example, a washing machine or other clothes processing device that needs to be provided with lifting ribs 1 to lift clothes.

[0050] The laundry processing device includes a drum and at least one lifting rib 1 as described above, and the lifting rib 1 is arranged on the inner wall of the drum. For example, one lifting rib 1 can be arranged on the drum, and multiple lifting ribs 1 can also be arranged according to needs. When multiple lifting ribs 1 are arranged, for example, the arrangement direction of each lifting rib 1 can be parallel to the axial direction of the drum. It can be understood that the arrangement direction of the lifting rib 1 refers to the direction from the first end to the second end of the lifting rib body.

[0051] like Figure 1As shown, the lifting rib 1 includes a lifting rib body, and the lifting rib body includes a first lifting portion 11 and a second lifting portion 12 arranged side by side, and a connecting portion 15 connecting the first lifting portion 11 and the second lifting portion 12. The lifting rib body includes a first end and a second end opposite to each other, and along the direction from the first end of the lifting rib body to the second end, the top height of the first lifting portion 11 gradually decreases, and the top height of the second lifting portion 12 gradually increases, so that two peak structures can be formed. In this way, when the drum of the clothing processing device rotates, it is easier for the lifting rib 1 to hang the clothes to lift them to a high place, which improves the lifting effect of the lifting rib 1 on the clothes, and is more conducive to shaking the clothes, so as to further improve the washing effect of the clothes. It should be noted that when the lifting rib 1 is arranged on the inner wall of the drum of the clothing processing device, the end of the first lifting portion 11 away from the wall connected to it is the top of the first lifting portion 11, and similarly, the end of the second lifting portion 12 away from the wall connected to it is the top of the second lifting portion 12.

[0052] In addition, the design of the two peak-shaped structures of the lifting ribs 1 in this embodiment is also beneficial to enhancing the turbulence intensity of water when it flows through the lifting ribs 1, thereby increasing the intensity of the water flow on the clothes, thereby improving the cleaning effect on the clothes.
