[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent applications with application numbers 202322959999.X filed on November 1, 2023, 202322955618.0 filed on November 1, 2023, and 202323123146.9 filed on November 17, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure belongs to the technical field of electrical equipment, and in particular relates to a drum component and a clothes processing device. Background Art

[0004] Clothes processing devices are widely used in daily life for washing clothes or drying clothes. The clothes processing device mainly includes a drum component. The drum component generally includes an inner drum and an outer drum. The inner drum is arranged in the outer drum, and the inner drum is mainly used to accommodate clothes. The outer drum is the main structure of the entire clothes processing device. Whether in the washing process or the drying process, water flows through the inner drum. For example: during the washing process, external water enters the inner drum, and after the washing is completed, the water is discharged to the outside of the inner drum. During dehydration, due to the current configuration of the inner drum and the poor water permeability and bubble removal effect of the water permeable holes, water cannot be discharged to the outside of the inner drum in time. In addition, during drying, the current water permeable holes on the inner drum cannot effectively assist in discharging moisture evenly and quickly. In summary, the washing and drying effects of clothes are poor.

[0005] The motor is usually assembled on the bearing seat, and the stability of the motor is ensured by the tight connection between the motor and the bearing seat. The installation accuracy of the motor stator is an important factor in ensuring the reliability of the motor operation.

[0006] In the related art, it is necessary to process components for positioning the stator on the bearing seat, which increases the complexity of the structure, thereby increasing the difficulty and steps of manufacturing and increasing the overall manufacturing cost. Therefore, there is room for improvement.

[0034] The technical solution of the present disclosure will be described below with reference to the accompanying drawings and specific embodiments.

[0035] As shown in FIG1 , some embodiments of the present disclosure provide a cylinder component, including an inner cylinder 100 , wherein lifting ribs 130 are provided inside the inner cylinder 100 .

[0036] Referring to Figures 1 and 2 , inner drum 100 is used in a laundry processing device, which can be a washing machine, dryer, or washer-dryer. Inner drum 100 and the laundry processing device enable water to better lift and tumble the laundry, facilitating better washing and enhancing cleaning results. During dehydration, water is more easily transferred to permeable holes 114a, increasing the speed and effectiveness of water permeation throughout inner drum 100. This, in turn, allows for better defoaming, reduced residue, and improved rinsing results during the dehydration phases of the main wash and rinse cycles.

[0037] In some embodiments, the inner cylinder 100 includes: a cylinder body 110 and a bottom plate 119, the bottom plate 119 and the cylinder body 110 are connected to form a accommodating chamber 112c, and a dehydration groove 114 is provided on the side wall 112a of the accommodating chamber 112c, which protrudes in a direction away from the axis of the accommodating chamber 112c; a plurality of guide portions 120 are arranged at intervals on the dehydration groove 114, and a plurality of water-permeable holes 114a are arranged at intervals along the direction of the gap 121 in the gap 121 between two adjacent guide portions 120.

[0038] The drum body 110 is the main body of the entire inner drum 100 and provides a receiving cavity 112c for receiving clothes.

[0039] The accommodating chamber 112c has side walls 112a and a bottom wall 112b. The side walls 112a are provided on the tub body 110, and the bottom wall 112b is provided on the bottom plate 118. The inner tub 100 also includes an inner tub front cover 117. The inner tub front cover 117 is provided with an opening 112d that communicates with the accommodating chamber 112c. When processing clothes, clothes can be placed into the accommodating chamber 112c through the opening 112d. After processing, the clothes can be taken out of the accommodating chamber 112c through the opening 112d.

[0040] It should be noted that the bottom wall 112b refers to the surface of the barrel 110 opposite the opening 112d. That is, the bottom wall 112b refers to the side of the entire barrel 110 opposite the opening 112d, and is not the lowest end of the entire inner barrel 100 during use. The bottom wall 112b or a portion thereof may be the lowest end of the entire barrel 110, or it may not be the lowest end of the entire barrel 110.

[0041] In some embodiments, when the axis of the barrel 110 is in a vertical direction, the bottom wall 112b is arranged below the opening 112d. When the axis of the barrel 110 is in a horizontal direction, the surfaces of the bottom wall 112b and the opening 112d are both arranged vertically. If it is assumed that the opening 112d is arranged in front of the barrel 110, the bottom wall 112b is arranged behind the barrel 110. Similarly, the axis of the barrel 110 can also be arranged at an angle. In some embodiments, the description is made by taking the horizontal arrangement of the axis of the barrel 110 as an example. That is, the bottom wall 112b is arranged vertically, and the opening 112d is arranged in front of the bottom wall 112b, which is convenient for taking and placing clothes. The accommodating chamber 112c is roughly cylindrical, and the side wall 112a is an annular surface.

[0042] In some embodiments, a dehydration trough 114 is provided on the side wall 112a, and the dehydration trough 114 protrudes in a direction away from the axis of the accommodating chamber 112c, that is, the distance between the bottom wall of the dehydration trough 114 and the axis of the accommodating chamber 112c is greater than the distance between other parts of the side wall 112a and the axis of the accommodating chamber 112c.

[0043] The water holes 114a are provided in the gaps 121 between the two adjacent guide portions 120. During dehydration, after water flows into the dehydration trough 114, the gaps 121 between the two adjacent guide portions 120 can guide and converge the water, allowing the water entering the dehydration trough 114 to converge along the gaps 121 between the two adjacent guide portions 120 and flow toward the water holes 114a, allowing the water to flow quickly toward the water holes 114a.

[0044] The water-permeable hole 114a is set in the gap 121 between two adjacent guide parts 120, so that water can be diverted through multiple different gaps 121, so that water can flow to different gaps 121, reducing the water flow pressure in the same gap 121, and avoiding the accumulation of water in the same gap 121 as much as possible, so that the water in the accommodating cavity 112c can be discharged from the water-permeable hole 114a to the outside of the accommodating cavity 112c in a more orderly manner.

[0045] A dewatering groove 114 is provided on the side wall 112a, protruding in a direction away from the accommodating chamber 112c. Water in the accommodating chamber 112c can be collected in the dewatering groove 114. After being collected in the dewatering groove 114, the water can flow to the water-permeable hole 114a through the gap 121 between two adjacent guide portions 120, and then flow out of the accommodating chamber 112c through the water-permeable hole 114a. By providing the dewatering groove 114 and the guide portion 120, the water in the accommodating chamber 112c can be drained and collected, so that the water can flow to the water-permeable hole 114a as quickly as possible, thereby improving the water permeability speed and water permeability effect of the entire inner cylinder 100.

[0046] In some embodiments, the inner cylinder 100 is generally cylindrical, and the accommodating chamber 112c is also cylindrical. The middle of the accommodating chamber 112c refers to the central axis of the accommodating chamber 112c. In the embodiments of the present disclosure, the terms "upper," "lower," "top," and "bottom" all refer to the positional relationship of the inner cylinder 100 in the working state.

[0047] In addition, multiple guide parts 120 are arranged in the dewatering trough 114, and two adjacent guide parts 120 form a gap 121, so there will be multiple gaps 121, and the widths between the multiple gaps 121 can be the same or different. The lengths of the multiple gaps 121 can be the same or different. The shapes of any two guide parts 120 can be the same or different, and the lengths of any two guide parts 120 can be the same or different. The heights of any two guide parts 120 relative to the dewatering trough 114 can be the same or different. The widths of any two guide parts 120 can be the same or different. The parameters of the gaps 121 and the guide parts 120 are not limited.

[0048] Referring to Figures 3 and 4, in some embodiments, the bottom plate 118 is disposed at one end of the cylinder 110, and the bottom wall 112b is disposed on a side of the bottom plate 118 adjacent to the cylinder 110. The cylinder 110 is a unitary structure formed by welding the ends of a generally rectangular stainless steel plate together to form the cylindrical cylinder 110. The dewatering trough 114 is protruded in a direction away from the axis of the accommodating chamber 112c, that is, the dewatering trough 114 protrudes from the outer circumference of the cylinder 110. This allows the dewatering trough 114 to be provided without increasing the thickness of the cylinder 110, that is, the dewatering trough 114 can be added without changing the structure of the cylinder 110, thereby minimizing the cost of adding the dewatering trough 114.

[0049] The thickness of the cylinder 110 is relatively thin. If the dewatering groove 114 is directly set on the cylinder 110, the depth of the dewatering groove 114 will be small and it will not be able to collect water. The dewatering groove 114 is protruded outward on the cylinder 110, which can increase the depth of the dewatering groove 114, thereby playing the role of drainage and water collection.

[0050] There can be multiple dehydration tanks 114, and the multiple dehydration tanks 114 can be evenly arranged on the circumference of the cylinder 110, for example, evenly distributed along the circumference, or there can be multiple groups, each group is evenly distributed along the circumference; and the groups are distributed along the axial direction.

[0051] In some embodiments, the barrel 110 and the dewatering trough 114 are integrally stamped. That is, during manufacturing, the dewatering trough 114 can be formed by directly stamping outward from the barrel 110. In other words, the thickness of the dewatering trough 114 is the same as that of the barrel 110. Stamping the dewatering trough 114 on the barrel 110 reduces the number of steps required to connect the barrel 110 and the dewatering trough 114, thereby reducing errors that may occur when connecting the barrel 110 and the dewatering trough 114 and lowering manufacturing costs.

[0052] In some embodiments, the guide portion 120 is integrally stamped and formed with the cylinder body 110. That is, the guide portion 120 is stamped inwardly on the dewatering groove 114, which can reduce the connection process between the guide portion 120 and the dewatering groove 114 and reduce the error caused by connecting the guide portion 120 and the dewatering groove 114.

[0053] In some embodiments, the plurality of guide portions 120 may be stamped at one time or in batches.

[0054] That is to say, in some embodiments, the cylinder 110, the dewatering trough 114 and the guide portion 120 are an integrated structure. The dewatering trough 114 and the guide portion 120 can be stamped on the plate of the cylinder 110 and then the ends of the plate are welded to form a cylindrical cylinder 110.

[0055] The guide portion 120 is arranged in the accommodating cavity 112c, and can increase the contact with the clothes during the washing or drying process, thereby increasing the friction between the clothes and the clothes, guiding the movement of the clothes, so that the clothes can be lifted as they rotate in the inner drum 100 and roll back and forth as the inner drum 100 rotates clockwise or counterclockwise, so as to achieve the effects of rubbing, shaking, and beating, thereby making the clothes better contact with water or hot air, so as to improve the washing or drying effect of the clothes.

[0056] The guide portion 120 extends along the axial direction of the drum 110 and can extend in a wave shape. During the rotation of the drum 110, the guide portion 120 can guide the clothes to move in the axial direction of the drum 110, thereby increasing the activity space of the clothes in the drum 110, thereby increasing the number of collisions between the clothes and the inner drum front cover 117 or the bottom wall 112b of the drum 110, thereby improving the washing effect.

[0057] The two sides of the guide portion 120 have gaps 121 with the adjacent guide portions 120, that is, there are two guide surfaces 123. The two guide surfaces 123 are respectively arranged on the two opposite sides of the guide portion 120, and the guide surfaces 123 are wavy in the axial direction of the barrel 110, so that the guide surfaces 123 have a certain changing curvature in the extension direction of the barrel 110. When the clothes are located in the gap 121, the guide surfaces 123 can play a guiding role for the clothes. The wavy guide surfaces 123 can continuously change the movement direction of the clothes in the axial direction of the barrel 110, so that different positions of the clothes can come into contact with water or hot air, thereby improving the washing or drying effect of the clothes.

[0058] Since there are two guide surfaces 123, one of the guide surfaces 123 may be wavy, or both guide surfaces 123 may be wavy. If both guide surfaces 123 are wavy, the changing trends of the two guide surfaces 123 may be the same or different.

[0059] In some embodiments, the wave shape is a periodic wave, and the ratio of the wavelength to the amplitude of the periodic wave is greater than 10. This indicates that the curvature of the guide surface 123 is relatively small, that is, the wavelength is relatively large and the amplitude is relatively small. The curvature of the guide surface 123 is relatively small. A water-permeable hole 114a is also provided between two adjacent guide portions 120. If the curvature of the guide surface 123 is set to be relatively large, the direction of water flow will change significantly, and the water flow will be too fast, causing water to splash back onto the clothes, affecting the washing or drying effect. Setting the ratio of the wavelength to the amplitude of the guide surface 123 to be greater than 10 makes the curvature of the guide surface 123 relatively small, so that the water can flow smoothly when diverting the water flow, and can be quickly discharged from the water-permeable hole 114a.

[0060] In some embodiments, the guide portion 120 is wavy in the axial direction of the cylinder 110. This means that the two oppositely disposed guide surfaces 123 have the same changing pattern, so that the projection of the guide portion 120 on the bottom of the dewatering tank 114 is the wavy shape as a whole.

[0061] In some embodiments, the length of the guide portion 120 extends at least 1 / 3, preferably more than 1 / 2, and more preferably more than 80%, of the axial length of the tubular body 110, and is less than one wavelength. This indicates that the wavelength of the guide portion 120 is large and the length of the guide portion 120 is short, i.e., the overall change trend of the guide portion 120 is relatively slow. During the drainage process, the water flow is minimized from being too rapid and splashing onto clothing, allowing the water to flow smoothly and be quickly discharged from the water-permeable holes 114a.

[0062] In some embodiments, the water hole 114a is located at the point where it is most distant from the central axis of the accommodating chamber 112c, i.e., at its radially outermost position. The height of the water hole 114a is lower than that of the sidewall 112a. Under the influence of gravity and centrifugal force, water can quickly flow out through the water hole 114a, thereby improving the water permeability and effectiveness of the entire inner drum 100.

[0063] In some embodiments, the drum 110 can be further divided into a mounting area 116b and a dehydration area 116a based on their functions. The two areas are separated by a busbar and spaced circumferentially. The dehydration troughs 114 are located in the dehydration area 116a. The inner drum 100 also includes lifting ribs 130, which are disposed within the accommodating cavity 112c and mounted in the mounting area 116b.

[0064] The dehydration tank 114 is disposed on the dehydration area 116 a , that is, the dehydration tank 114 does not completely extend to both ends of the cylinder 110 .

[0065] The lifting ribs 130 are installed in the accommodating cavity 112c of the inner drum 100, and are mainly used to drive the clothes to move in the circumferential direction of the inner drum 100 during the washing or drying process, so that the clothes can move to the middle and upper part of the accommodating cavity 112c, and then fall from the top under the action of gravity. During this process, the clothes rub against each other and may collide with the side 133 or the bottom 132 of the accommodating cavity 112c, thereby achieving the effect of rubbing, throwing, and shaking out the clothes, so as to wash or dry the clothes.

[0066] For the convenience of description, the position where the clothes are separated from the lifting ribs 130 is defined as the dropping point. The higher the dropping point, the better the impact force, the falling and shaking effect of the clothes on the inner drum 100 during washing, and the better the shaking effect during drying, and the longer the contact time with the hot air in the inner drum 100, thereby improving the washing and drying effects.

[0067] In some embodiments, there are multiple dehydration zones 116a and multiple installation zones 116b, and the multiple dehydration zones 116a and the multiple installation zones 116b are alternately arranged. Each installation zone 116b is provided with a lifting rib 130, and one of the lifting ribs 130 covers the weld of the barrel 110. The lifting rib 130 covers the weld, which can increase the strength of the barrel 110 when rubbing clothes, reduce the possibility of separation of the weld of the barrel 110 and damage to the barrel 110, and improve the aesthetic effect by covering part of the weld.

[0068] Referring to Figures 5 and 6 , in some embodiments, the lifting rib 130 has a top surface 131, a bottom surface 132, and at least two side surfaces 133. The top surface 131 and the bottom surface 132 are disposed opposite each other. The top surface 131 has at least two side edges 131a, and a side surface 133 connects one side edge 131a and the bottom surface 132. At least one side edge 131a is wavy.

[0069] In some embodiments, bottom surface 132 refers to the surface connected to bottom wall 112b of inner tube 100. Top surface 131 refers to the surface facing the center of accommodating cavity 112c of inner tube 100. Side surface 133 connects bottom surface 132 and top surface 131 and extends in the axial direction of inner tube 100.

[0070] At least one side 131a is wavy, and may be only one side 131a, two sides 131a, or all sides 131a. When at least two sides 131a are wavy, the shapes of the waves on the two sides 131a can be the same or different, that is, the amplitudes can be the same or different, and the wavelengths can be the same or different.

[0071] When the side 131a is wavy, since the side 133 connects the side 131a and the bottom 132, the shape of the side 133 will change with the shape of the side 131a, so that the shape of the side 133 will also be roughly wavy. When the lifting ribs 130 are lifting the clothes, the clothes are mainly driven to move in the circumferential direction of the inner drum 100 through the side 131a and the side 133. The wavy shape of the side 131a and the side 133 can imitate the shape of a person's hand contacting the clothes during the lifting process. As the inner drum 100 rotates continuously, the clothes constantly contact the side 131a and the side 133, which can imitate the rubbing of the clothes by the hands of the people, causing the clothes to collide with water, the side wall 112a, the clothes, or hot air, causing them to be thrown and shaken off, thereby improving the washing and drying effects.

[0072] In some embodiments, the lifting rib 130 is generally elongated, with two side surfaces 133 and two side edges 131a, both of which are wavy. The bottom surface 132 is primarily used to engage with the side wall 112a of the inner cylinder 100. To ensure a secure installation of the lifting rib 130 within the inner cylinder 100, the bottom surface 132 is shaped to match the side wall 112a of the inner cylinder 100. In other words, the side surfaces 133 are not a standard wavy shape; the wavy shape is more pronounced closer to the side edge 131a.

[0073] In some embodiments, the wavy shape is a periodic function wave. This indicates that the shape of the side edge 131a is regular. Setting it as a periodic function wave facilitates the shaping of the wavy side edge 131a and reduces the difficulty of processing the side edge 131a. Furthermore, the wavy shape is a periodic function wave, which enables the side edge 131a to be regular. During contact with clothing, different positions of the side edge 131a exert roughly the same force on the clothing, reducing damage to the clothing caused by different forces.

[0074] In some embodiments, the ratio of the wavelength to the amplitude of the periodic function wave is less than or equal to 20. This indicates that the wavelength of the side edge 131a is shorter and the amplitude is larger, resulting in a greater degree of curvature of the side edge 131a. As the lifting ribs 130 drive the clothing to move circumferentially within the inner drum 100, the contact area with the clothing can be increased, allowing the side edges 131a and side surfaces 133 to contact the clothing at as many locations as possible, thereby driving the clothing to a higher position within the inner drum 100. The higher the highest position of the clothing, the greater the impact force with the inner drum 100 during the fall, the longer the time spent in the air, and the more sufficient contact with water or air, thereby improving the cleaning or drying effect.

[0075] The amplitude and wavelength of the periodic function wave can be set according to the size of the entire inner tube 100. In some embodiments, the amplitude of the periodic function wave can be 5 mm to 15 mm, and the wavelength of the periodic function wave can be 70 mm to 100 mm.

[0076] In some embodiments, the length of the side 131a is greater than or equal to one wavelength. The length of the side 131a is the same as the length of the top surface 131. In other words, the side 131a has at least one complete crest or trough and at least two bending changes. The more crests and troughs there are, the better the rubbing effect on the clothes, which can improve the cleaning effect of the clothes.

[0077] The length of the side 131 a can be set according to the size of the inner cylinder 100 , and can be the same as the length of the axis or generatrix of the inner cylinder 100 , or can be less than the axial length of the inner cylinder 100 .

[0078] In some embodiments, the top surface 131 is wavy. This means that both side edges 131a are wavy, with the same wavelength and amplitude. The wavy top surface 131 ensures that the inner drum 100 contacts the clothing in the same manner during both forward and reverse rotations, ensuring that the lifting height and kneading force of the clothing are approximately the same during both forward and reverse rotations, resulting in a roughly consistent cleaning effect during the washing process, thereby improving the overall cleaning effect.

[0079] In some embodiments, the top surface 131 has a first end 131b and a second end 131c in the extending direction of the lifting ribs 130, and the distance between the first end 131b and the bottom surface 132 is equal to the distance between the second end 131c and the bottom surface 132. During the washing process, the difficulty of the clothes from both ends of the lifting ribs 130 overlapping the side surfaces 133 and the top surface 131 is the same. In other words, the friction force with the clothes is substantially the same during both forward and reverse rotations, thereby ensuring that the clothes can be lifted to the same height during both forward and reverse rotations, thereby ensuring a good washing effect.

[0080] In some embodiments, if the clothes are mainly overlapped on the top surface 131 and the side surface 133 from the first end 131b during forward rotation, and are mainly overlapped on the top surface 131 and the side surface 133 from the second end 131c during reverse rotation, the rotation speeds during forward and reverse rotation are substantially the same, the distances between the first end 131b and the bottom surface 132 and the distances between the second end 131c and the bottom surface 132 are the same, and during the rotation process, the difficulty of the clothes moving from the first end 131b to the top surface 131 and the side surface 133 is the same as the difficulty of moving from the second end 131c to the top surface 131 and the side surface 133. As a result, the clothes can be lifted to the same height during both forward and reverse rotation, thereby ensuring the cleaning effect of the clothes.

[0081] In some embodiments, the top surface 131 is a plane. It can be assumed that the distance between the top surface 131 and the side wall 112a of the inner drum 100 is the same. During the washing process, the difficulty of the clothes from both ends of the lifting ribs 130 overlapping the side surfaces 133 and the top surface 131 is the same. In other words, the friction force with the clothes is roughly the same during forward and reverse rotation, thereby ensuring that the clothes can be lifted to the same height during both forward and reverse rotation, thereby ensuring the washing effect of the clothes.

[0082] Since the distances between the top surface 131 and the side wall 112a of the inner drum 100 are different, the lifting heights of the clothes by the lifting ribs 130 will be different. If the top surface 131 is set to a plane, the distances between the top surface 131 and the side wall 112a of the inner drum 100 are the same. Therefore, no matter where the clothes contact the top surface 131, the clothes can be lifted to roughly the same height, thereby ensuring the cleaning effect of the clothes.

[0083] In some embodiments, the lifting rib 130 further has two end surfaces 134 , which respectively connect the two ends of the top surface 131 and the bottom surface 132 . Both end surfaces 134 are inclined from the bottom surface 132 toward the top surface 131 .

[0084] The two end surfaces 134 respectively connect the first end 131b and the bottom surface 132 and the second end 131c and the bottom surface 132. The bottom surface 132 of both end surfaces 134 is tilted toward the top surface 131, so that the two end surfaces 134 can have a certain guiding effect, which can reduce the difficulty of the clothes being attached to the lifting ribs 130 during the rotation process, and avoid as much as possible the situation where the clothes cannot be attached to the lifting ribs 130 during the rotation process; and enable the clothes to smoothly detach from the lifting ribs 130 at the dropping point.

[0085] In some embodiments, the projection of the top surface 131 on the bottom surface 132 is located inside the bottom surface 132. This means that the area of ​​the top surface 131 is smaller and the area of ​​the bottom surface 132 is larger. The surfaces connecting the top surface 131 and the bottom surface 132 are all inclined, that is, the two end surfaces 134 and the two side surfaces 133 are all inclined, so that the end surfaces 134 and the side surfaces 133 can have a certain guiding ability. During the rotation of the inner drum 100, the clothes can be overlapped on the lifting ribs 130 to avoid excessive wear on the clothes and make the lifting ribs 130 gently contact the clothes. It is easier to separate the clothes from the lifting ribs 130 at the drop point to avoid pulling on the clothes. The clothes are lifted to a higher place by the lifting ribs 130 and then dropped. During the falling process, they come into contact with and collide with the inner drum 100, and can fully come into contact with water or air, thereby improving the washing effect or drying effect.

[0086] In some embodiments, the distance between the top surface 131 and the bottom surface 132 is 20 mm to 30 mm. The distance between the top surface 131 and the bottom surface 132 is the height of the lifting ribs 130. The higher the height of the lifting ribs 130, the greater the friction between the lifting ribs 130 and the clothes, and the higher the clothes can be lifted in the inner drum 100, that is, the higher the point at which the clothes are dropped. However, excessive friction can make it difficult for the clothes to detach from the lifting ribs 130 and cause excessive wear on the clothes. If the height is lower, the point at which the clothes are dropped in the inner drum 100 will be lower, and the clothes will fall a shorter distance in the inner drum 100, resulting in a shorter contact time with water and air, resulting in poor washing and drying performance.

[0087] The distance between the top surface 131 and the bottom surface 132 is 20 mm to 30 mm, which ensures that the dropping point is in the upper middle of the inner drum 100, thereby increasing the impact force with the inner drum 100 and the falling time in the inner drum 100, resulting in a significant kneading effect, better throwing and shaking effects, and improved cleaning and drying effects.

[0088] In some embodiments, the projection width of the top surface 131 in the extension direction of the lifting rib 130 is 15 mm to 25 mm.

[0089] The lifting ribs 130 are arranged along the generatrix extending direction of the inner cylinder 100. The projection of the top surface 131 along the extending direction of the lifting ribs 130 is the projection of the top surface 131 along the extending direction of the inner cylinder 100. The projection of the top surface 131 along the extending direction of the inner cylinder 100 is the sum of the two amplitudes of the wave shape and the width of the top surface 131.

[0090] The projection width of the top surface 131 in the extension direction of the lifting rib 130 is 15 mm to 25 mm, which can increase the collision force of the lifting rib 130 when it contacts the clothes, that is, it can increase the rubbing force on the clothes and improve the cleaning effect on the clothes.

[0091] In some embodiments, the length of the top surface 131 is 120 mm to 150 mm, and the length of the bottom surface 132 is 140 mm to 180 mm. The lengths of the top surface 131 and the bottom surface 132 can be set based on the axial length of the inner drum 100. Setting these lengths maximizes the use of the structure within the accommodating cavity 112 c of the inner drum 100, thereby improving the contact effect between the lifting ribs 130 and the clothing.

[0092] In some embodiments, the lifting rib 130 has a water outlet cavity 136 therein, the bottom surface 132 has a water outlet 139 in a generally rectangular shape that communicates with the water outlet cavity 136, and the top surface 131 is provided with a water outlet hole 135 that communicates with the water outlet cavity 136. That is, the lifting rib 130 has a hollow interior and the water outlet hole 135 is provided on the top surface 131. During the cleaning process, water in the tubular member can flow out through the water outlet 139, the water outlet cavity 136, and the water outlet hole 135 in sequence, thereby achieving a spraying effect.

[0093] Please refer to FIG. 3 and FIG. 7 . In some embodiments, one of the bottom surface 132 and the mounting area 116 b has a clamping portion 137 , and the other has a clamping slot 119 . The clamping portion 137 is clamped with the clamping slot 119 .

[0094] One of the bottom surface 132 and the mounting area 116b is provided with a holding portion 137, and the other is provided with a holding groove 119. Alternatively, the holding portion 137 may be provided on the bottom surface 132 and the holding groove 119 may be provided on the mounting area 116b. Alternatively, the holding groove 119 may be provided on the bottom surface 132 and the mounting area 116b, as long as the holding portion 137 and the holding groove 119 are engaged.

[0095] The lifting rib 130 is fixed to the installation area 116b by clamping the clamping portion 137 and the clamping groove 119. During the assembly process, the clamping portion 137 can play a certain guiding role, which can facilitate the assembly of the lifting rib 130 on the inner cylinder 100. After the clamping portion 137 and the clamping groove 119 are clamped, they can provide a certain positioning and fixing effect for the lifting rib 130.

[0096] In some embodiments, under the condition that a clamping groove 119 is set in the installation area 116b, the clamping groove 119 has a first groove section 119a and a second groove section 119b that are connected, the width of the first groove section 119a is greater than the width of the second groove section 119b, the second groove section 119b is clamped with the clamping portion 137, and the first groove section 119a is connected to the water outlet cavity 136 of the lifting rib 130.

[0097] During assembly, the retaining portion 137 is first inserted into the first groove section 119a and then slid toward the second groove section 119b, causing the retaining portion 137 to engage with the second groove section 119b. Furthermore, due to the greater width of the first groove section 119a, the first groove section 119a can also serve as a water inlet, allowing water to more easily enter the water outlet chamber 136.

[0098] Referring to Figures 3 and 6 , in some embodiments, the inner cylinder 100 further includes a fixing member. The mounting area 116b is provided with a first fixing hole 116c, and the bottom surface 132 is provided with a second fixing hole 138. The fixing member securely connects the first fixing hole 116c and the second fixing hole 138. After the retaining portion 137 and the retaining groove 119 are engaged, the fixing member passes through the first fixing hole 116c and the second fixing hole 138, thereby securing the lifting rib 130 to the cylinder body 110. After the retaining groove 119 and the retaining portion 137 form a preliminary fixation, the retaining member further securely secures the lifting rib 130 by engaging with the first fixing hole 116c and the second fixing hole 138.

[0099] In addition, reinforcing ribs are provided around the second fixing hole 138 to connect to the side wall of the water outlet cavity 136 to strengthen the fixation of the second fixing hole 138 .

[0100] Please refer to FIG. 5 and FIG. 6 . In some embodiments, the lifting ribs 130 are installed in the accommodating cavity 112 c of the inner drum 100 . The lifting ribs 130 can improve the rubbing effect on the clothes, thereby improving the cleaning effect on the clothes.

[0101] In some embodiments, the lifting rib 130 has: a top surface 131, a bottom surface 132 and at least two side surfaces 133, the top surface 131 and the bottom surface 132 are arranged opposite to each other, the top surface 131 has at least two side edges 131a, a side surface 133 connects a side edge 131a and the bottom surface 132, and at least one side edge 131a is wavy.

[0102] The lifting ribs 130 are installed in the accommodating cavity 112c of the inner drum 100, and are mainly used to drive the clothes to move in the circumferential direction of the inner drum 100 during the washing or drying process, so that the clothes can move to the middle and upper part of the accommodating cavity 112c, and then fall from the top under the action of gravity. During this process, the clothes rub against each other and may collide with the side 133 or the bottom 132 of the accommodating cavity 112c, thereby achieving the effect of kneading, throwing, and shaking out the clothes, so as to wash or dry the clothes.

[0103] For the convenience of description, the position where the clothes are separated from the lifting ribs 130 is defined as the dropping point. The higher the dropping point, the better the impact force, the falling and shaking effect of the clothes on the inner drum 100 during washing, and the better the shaking effect during drying, and the longer the contact time with the hot air in the inner drum 100, thereby improving the washing and drying effects.

[0104] In some embodiments, the bottom surface 132 refers to the surface connected to the bottom wall 112b of the inner tube 100, the top surface 131 is only the surface facing the middle of the accommodating cavity 112c of the inner tube 100, and the side surface 133 is the two surfaces connecting the bottom surface 132 and the top surface 131, and the side surface 133 extends in the axial direction of the inner tube 100.

[0105] At least one side 131a is wavy, and may be only one side 131a, two sides 131a, or all sides 131a. When at least two sides 131a are wavy, the shapes of the waves on the two sides 131a can be the same or different, that is, the amplitudes can be the same or different, and the wavelengths can be the same or different.

[0106] When the side edges 131a are wavy, since the side edges 133 connect the side edges 131a and the bottom surface 132, the shape of the side edges 133 changes with the shape of the side edges 131a, resulting in the side edges 133 also being roughly wavy. When the lifting ribs 130 lift the clothes, they primarily move the clothes around the inner drum 100 via the side edges 131a and the side edges 133. The wavy shape of the side edges 131a and the side edges 133 can simulate the contact of a person's hand with the clothes during the lifting process. As the inner drum 100 rotates, the clothes constantly come into contact with the side edges 131a and the side edges 133, mimicking the contact of a person's hand with the clothes, causing the clothes to collide with water, the sidewalls 112a of the inner drum 100, the clothes, or even hot air, causing them to bounce and fall, thereby improving the cleaning effect.

[0107] In some embodiments, the lifting rib 130 is generally elongated, with two side surfaces 133 and two side edges 131a, both of which are wavy. The bottom surface 132 is primarily used to engage with the side wall 112a of the inner cylinder 100. To ensure a secure installation of the lifting rib 130 within the inner cylinder 100, the bottom surface 132 is shaped to match the side wall 112a of the inner cylinder 100. In other words, the side surfaces 133 are not a standard wavy shape; the wavy shape is more pronounced closer to the side edge 131a.

[0108] In some embodiments, the wavy shape is a periodic function wave. This indicates that the shape of the side edge 131a is regular. Setting it as a periodic function wave facilitates the shaping of the wavy side edge 131a and reduces the difficulty of processing the side edge 131a. Furthermore, the wavy shape is a periodic function wave, which can make the side edge 131a regular. During contact with clothing, different positions of the side edge 131a exert roughly the same force on the clothing, reducing damage to the clothing caused by different forces.

[0109] In some embodiments, the ratio of the wavelength to the amplitude of the periodic function wave is less than or equal to 20. This indicates that the wavelength of the side edge 131a is shorter and the amplitude is larger, resulting in a greater degree of curvature of the side edge 131a. As the lifting ribs 130 drive the clothing to move in the circumferential direction of the inner drum 100, the contact area between the lifting ribs 130 and the clothing is increased, so that as many positions of the side edge 131a and the side surface 133 as possible come into contact with the clothing, thereby driving the clothing to a higher position in the inner drum 100. The higher the highest position of the clothing, the greater the impact force with the inner drum 100 during the fall, the longer the time the clothing spends in the air, and the more sufficient contact with water or air, thereby improving the cleaning or drying effect.

[0110] The amplitude and wavelength of the periodic function wave can be set according to the size of the entire inner tube 100. In some embodiments, the amplitude of the periodic function wave can be 2 mm to 15 mm, and the wavelength of the periodic function wave can be 20 mm to 100 mm.

[0111] In some embodiments, the length of the side 131a is greater than or equal to one wavelength. The length of the side 131a is the same as the length of the top surface 131. In other words, the side 131a has at least one complete crest or trough and at least two bending changes. The more crests and troughs there are, the better the rubbing effect on the clothes, which can improve the cleaning effect of the clothes.

[0112] The length of the side 131 a can be set according to the size of the inner cylinder 100 , and can be the same as the length of the axis or generatrix of the inner cylinder 100 , or can be less than the axial length of the inner cylinder 100 .

[0113] In some embodiments, the top surface 131 is wavy. This means that both side edges 131a are wavy, with the same wavelength and amplitude. The wavy top surface 131 ensures that the inner drum 100 contacts the clothing in the same manner during both forward and reverse rotations, ensuring that the lifting height and kneading force of the clothing are approximately the same during both forward and reverse rotations, resulting in a roughly consistent cleaning effect during the washing process, thereby improving the overall cleaning effect.

[0114] In some embodiments, the top surface 131 has a first end 131b and a second end 131c in the extending direction of the lifting ribs 130, and the distance between the first end 131b and the bottom surface 132 is equal to the distance between the second end 131c and the bottom surface 132. During the washing process, the difficulty of the clothes from both ends of the lifting ribs 130 overlapping the side surfaces 133 and the top surface 131 is the same. In other words, the friction force with the clothes is substantially the same during both forward and reverse rotations, thereby ensuring that the clothes can be lifted to the same height during both forward and reverse rotations, thereby ensuring a good washing effect.

[0115] In some embodiments, if the clothes are mainly overlapped on the top surface 131 and the side surface 133 from the first end 131b during forward rotation, and are mainly overlapped on the top surface 131 and the side surface 133 from the second end 131c during reverse rotation, the rotation speeds during forward and reverse rotation are substantially the same, the distances between the first end 131b and the bottom surface 132 and the distances between the second end 131c and the bottom surface 132 are the same, and during the rotation process, the difficulty of the clothes moving from the first end 131b to the top surface 131 and the side surface 133 is the same as the difficulty of moving from the second end 131c to the top surface 131 and the side surface 133. As a result, the clothes can be lifted to the same height during both forward and reverse rotation, thereby ensuring the cleaning effect of the clothes.

[0116] In some embodiments, the top surface 131 is a plane. It can be assumed that the distance between the top surface 131 and the side wall 112a of the inner drum 100 is the same. During the washing process, the difficulty of the clothes from both ends of the lifting ribs 130 overlapping the side surfaces 133 and the top surface 131 is the same. In other words, the friction force with the clothes is roughly the same during forward and reverse rotation, thereby ensuring that the clothes can be lifted to the same height during both forward and reverse rotation, thereby ensuring the washing effect of the clothes.

[0117] In some embodiments, since the different distances between the top surface 131 and the side wall 112a of the inner drum 100 will cause the lifting heights of the clothes by the lifting ribs 130 to be different, the top surface 131 is set to be a plane, that is, the distance between the top surface 131 and the side wall 112a of the inner drum 100 is the same. Regardless of where the clothes contact the top surface 131, the clothes can be lifted to approximately the same height to ensure the cleaning effect of the clothes.

[0118] In some embodiments, the lifting rib 130 further has two end surfaces 134 , which respectively connect the two ends of the top surface 131 and the bottom surface 132 . Both end surfaces 134 are inclined from the bottom surface 132 toward the top surface 131 .

[0119] The two end surfaces 134 respectively connect the first end 131b and the bottom surface 132 and the second end 131c and the bottom surface 132. The bottom surface 132 of both end surfaces 134 is tilted toward the top surface 131, so that the two end surfaces 134 can have a certain guiding effect, which can reduce the difficulty of the clothes being attached to the lifting ribs 130 during the rotation process, and avoid as much as possible the situation where the clothes cannot be attached to the lifting ribs 130 during the rotation process; and enable the clothes to smoothly detach from the lifting ribs 130 at the dropping point.

[0120] In some embodiments, the projection of the top surface 131 on the bottom surface 132 is located within the bottom surface 132. This indicates that the area of ​​the top surface 131 is smaller and the area of ​​the bottom surface 132 is larger. The surfaces connecting the top surface 131 and the bottom surface 132 are all inclined, that is, the two end surfaces 134 and the two side surfaces 133 are all inclined, so that the end surfaces 134 and the side surfaces 133 can have a certain guiding ability. During the rotation of the inner drum 100, the clothes can be overlapped on the lifting ribs 130, avoiding excessive wear on the clothes, making the lifting ribs 130 gently contact the clothes, and making it easier to separate the clothes from the lifting ribs 130 at the drop point, avoiding pulling on the clothes. The clothes are lifted to a higher place by the lifting ribs 130 and then dropped. During the fall, they come into contact with and collide with the inner drum 100, and can fully come into contact with water or air, thereby improving the cleaning or drying effect.

[0121] In some embodiments, the distance between the top surface 131 and the bottom surface 132 is 15 mm to 50 mm. The distance between the top surface 131 and the bottom surface 132 is the height of the lifting rib 130. The higher the height of the lifting rib 130, the greater the friction between the lifting rib 130 and the clothes, and the higher the height of the clothes in the inner drum 100 can be driven, that is, the higher the point at which the clothes are dropped. However, excessive friction will make it difficult for the clothes to detach from the lifting rib 130 and cause excessive wear on the clothes. If the height is shorter, the point at which the clothes are dropped in the inner drum 100 will be lower, the distance the clothes fall in the inner drum 100 will be shorter, and the contact time with water and air will be shorter, resulting in poor washing and drying experience.

[0122] The distance between the top surface 131 and the bottom surface 132 is 15 mm to 50 mm. This ensures that the dropping point is in the upper middle of the inner drum 100, thereby increasing the impact force with the inner drum 100 and the falling time in the inner drum 100, resulting in a significant kneading effect, better throwing and shaking effects, and improved cleaning and drying effects.

[0123] In some embodiments, the projection width of the top surface 131 in the extension direction of the lifting rib 130 is 10 mm to 55 mm.

[0124] The lifting ribs 130 are arranged along the extension direction of the inner cylinder 100. The projection of the top surface 131 in the extension direction of the lifting ribs 130 is the projection of the top surface 131 in the extension direction of the inner cylinder 100. The projection of the top surface 131 in the extension direction of the inner cylinder 100 is the sum of the two amplitudes of the wave shape and the width of the top surface 131.

[0125] The projection width of the top surface 131 in the extension direction of the lifting rib 130 is 10 mm to 55 mm, which can increase the collision force of the lifting rib 130 when it contacts the clothes, that is, it can increase the rubbing force on the clothes and improve the cleaning effect on the clothes.

[0126] In some embodiments, the length of the top surface 131 is 120 mm to 350 mm, and the length of the bottom surface 132 is 140 mm to 380 mm. The lengths of the top surface 131 and the bottom surface 132 can be set based on the axial length of the inner drum 100. Setting these lengths maximizes the use of the structure within the accommodating cavity 112 c of the inner drum 100, thereby improving the contact effect between the lifting ribs 130 and the clothing.

[0127] In some embodiments, the lifting rib 130 has a water outlet cavity 136 therein, the bottom surface 132 has a water outlet 139 in a generally rectangular shape that communicates with the water outlet cavity 136, and the top surface 131 is provided with a water outlet hole 135 that communicates with the water outlet cavity 136. That is, the lifting rib 130 has a hollow interior and the water outlet hole 135 is provided on the top surface 131. During the cleaning process, water in the tubular member can flow out through the water outlet 139, the water outlet cavity 136, and the water outlet hole 135 in sequence, thereby achieving a spraying effect.

[0128] In summary, the lifting ribs 130 provided in the disclosed embodiment, when the side edges 131a are wavy, since the side edges 133 connect the side edges 131a and the bottom surface 132, the shape of the side edges 133 will change with the shape of the side edges 131a, so that the shape of the side edges 133 will also be roughly wavy. When the lifting ribs 130 are lifting the clothes, they mainly drive the clothes to move in the circumferential direction of the inner drum 100 through the side edges 131a and the side edges 133. The wavy shape of the side edges 131a and the side edges 133 can simulate the shape of a person's hand contacting the clothes during the lifting process. As the inner drum 100 continuously rotates, the clothes constantly contact the side edges 131a and the side edges 133, which can simulate the rubbing of clothes by human hands, causing the clothes to collide with water or hot air, causing them to hit or fall, thereby improving the cleaning effect.

[0129] Please refer to Figures 1, 2, 4 and 3. Based on the same inventive concept, the embodiment of the present disclosure further provides an inner drum 100. The inner drum 100 provided in the embodiment of the present disclosure can improve the rubbing effect on clothes, thereby improving the cleaning effect on clothes.

[0130] In some embodiments, the inner drum 100 includes a drum body 110 and the aforementioned lifting ribs 130 . The drum body 110 includes an installation area 116 b and a dehydration area 116 a . The lifting ribs 130 are installed in the installation area 116 b .

[0131] The inner cylinder 100 includes: a cylinder body 110 and a bottom plate 118. The bottom plate 118 and the cylinder body 110 are connected to form a receiving chamber 112c. A dehydration groove 114 is provided on the side wall 112a of the receiving chamber 112c and protrudes in a direction away from the axis of the receiving chamber 112c. A plurality of guide portions 120 are arranged at intervals on the dehydration groove 114, and a plurality of water-permeable holes 114a are provided in the gap 121 between two adjacent guide portions 120.

[0132] In some embodiments, the drum body 110 is the main body of the entire inner drum 100 and provides a receiving cavity 112c for receiving clothes.

[0133] The accommodating chamber 112c has side walls 112a and a bottom wall 112b. The side walls 112a are provided on the tub body 110, and the bottom wall 112b is provided on the bottom plate 118. The inner tub 100 also includes an inner tub front cover 117. The inner tub front cover 117 is provided with an opening 112d that communicates with the accommodating chamber 112c. When processing clothes, clothes can be placed into the accommodating chamber 112c through the opening 112d. After processing, the clothes can be taken out of the accommodating chamber 112c through the opening 112d.

[0134] It should be noted that the bottom wall 112b refers to the surface of the barrel 110 opposite the opening 112d. That is, the bottom wall 112b refers to the side of the entire barrel 110 opposite the opening 112d, and is not the lowest end of the entire inner barrel 100 during use. The bottom wall 112b may be the lowest end of the entire barrel 110, or it may not be the lowest end of the entire barrel 110.

[0135] In some embodiments, when the axis of the barrel 110 is in a vertical direction, the bottom wall 112b is arranged below the opening 112d. When the axis of the barrel 110 is in a horizontal direction, the bottom wall 112b and the opening 112d are both arranged vertically. If it is assumed that the opening 112d is arranged in front of the barrel 110, the bottom wall 112b is arranged behind the barrel 110. Similarly, the axis of the barrel 110 can also be arranged at an angle. In some embodiments, the description is made by taking the horizontal arrangement of the axis of the barrel 110 as an example. That is, the bottom wall 112b is arranged vertically, and the opening 112d is arranged in front of the bottom wall 112b, which is convenient for taking and placing clothes. The accommodating chamber 112c is roughly cylindrical, and the side wall 112a is an annular surface.

[0136] In some embodiments, a dehydration trough 114 is provided on the side wall 112a, and the dehydration trough 114 protrudes in a direction away from the accommodating chamber 112c, that is, the distance between the bottom wall of the dehydration trough 114 and the middle of the accommodating chamber 112c is greater than the distance between the side wall 112a and the middle of the accommodating chamber 112c.

[0137] The water-permeable hole 114a is set in the gap 121 between the two adjacent guide parts 120. During dehydration, after the water flows into the dehydration groove 114, the gap 121 between the two adjacent guide parts 120 can guide and converge the water, so that the water entering the dehydration groove 114 can converge along the gap 121 between the two adjacent guide parts 120 and flow toward the water-permeable hole 114a, so that the water can flow quickly toward the water-permeable hole 114a.

[0138] The water-permeable hole 114a is set in the gap 121 between two adjacent guide parts 120, so that water can be diverted through multiple different gaps 121, so that water can flow to different gaps 121, reducing the water flow pressure in the same gap 121, and avoiding the accumulation of water in the same gap 121 as much as possible, so that the water in the accommodating cavity 112c can be discharged from the water-permeable hole 114a to the outside of the accommodating cavity 112c in a more orderly manner.

[0139] A dewatering groove 114 is provided on the sidewall 112a, protruding away from the accommodating chamber 112c. Water within the accommodating chamber 112c is collected in the dewatering groove 114. After collecting in the dewatering groove 114, the water flows through the gap 121 between two adjacent guide portions 120 to the water-permeable hole 114a, and then flows out of the accommodating chamber 112c through the water-permeable hole 114a. The provision of the dewatering groove 114 and the guide portion 120 can drain and collect the water within the accommodating chamber 112c, allowing the water to flow to the water-permeable hole 114a as quickly as possible, thereby improving the water permeability and water permeability of the entire inner drum 100.

[0140] In some embodiments, the inner cylinder 100 is generally cylindrical, and the accommodating chamber 112c is also cylindrical. The middle of the accommodating chamber 112c refers to the central axis of the accommodating chamber 112c. In the embodiments of the present disclosure, the terms "upper," "lower," "top," and "bottom" all refer to the positional relationship of the inner cylinder 100 in the working state.

[0141] In some embodiments, a plurality of guide portions 120 are disposed in the dewatering trough 114, and two adjacent guide portions 120 form a gap 121, so there are multiple gaps 121. The widths of the multiple gaps 121 can be the same or different, and the lengths of the multiple gaps 121 can be the same or different. The shapes of any two guide portions 120 can be the same or different, and the lengths of any two guide portions 120 can be the same or different. The heights of any two guide portions 120 relative to the dewatering trough 114 can be the same or different. The widths of any two guide portions 120 can be the same or different. The parameters of the gaps 121 and the guide portions 120 may not be limited.

[0142] Referring to Figures 1, 2, and 4, in some embodiments, a bottom plate 118 is disposed at one end of the cylinder 110, and a bottom wall 112b is disposed on a side of the bottom plate 118 close to the cylinder 110. The cylinder 110 is an integral structure, formed by welding the ends of a roughly rectangular stainless steel plate together to form a cylindrical cylinder 110. The dewatering trough 114 is protruded in a direction away from the accommodating chamber 112c, that is, the dewatering trough 114 protrudes from the outer circumference of the cylinder 110. This allows the dewatering trough 114 to be provided without increasing the thickness of the cylinder 110, that is, without changing the structure of the cylinder 110, thereby minimizing the cost of providing the dewatering trough 114.

[0143] The thickness of the cylinder 110 is relatively thin. If the dewatering groove 114 is directly set on the cylinder 110, the depth of the dewatering groove 114 will be small and it will not be able to collect water. The dewatering groove 114 is protruded outward on the cylinder 110, which can increase the depth of the dewatering groove 114, thereby playing the role of drainage and water collection.

[0144] There can be multiple dehydration tanks 114, and the multiple dehydration tanks 114 can be evenly arranged on the circumference of the cylinder 110, for example, evenly distributed along the circumference, or there can be multiple groups, each group is evenly distributed along the circumference; and the groups are distributed along the axial direction.

[0145] In some embodiments, the barrel 110 and the dewatering trough 114 are integrally stamped. That is, during manufacturing, the dewatering trough 114 can be formed by directly stamping outward from the barrel 110. In other words, the thickness of the dewatering trough 114 is the same as that of the barrel 110. Stamping the dewatering trough 114 on the barrel 110 reduces the number of steps required to connect the barrel 110 and the dewatering trough 114, thereby reducing errors that may occur when connecting the barrel 110 and the dewatering trough 114 and lowering manufacturing costs.

[0146] In some embodiments, there are multiple dehydration zones 116a and multiple installation zones 116b, which are alternately arranged. Each installation zone 116b is provided with a lifting rib 130, one of which covers the weld of the barrel 110. The lifting rib 130 covers the weld, which can rub the clothes and increase the strength of the barrel 110, thereby reducing the possibility of the weld of the barrel 110 detaching and causing damage to the barrel 110.

[0147] Please refer to FIG. 3 and FIG. 7 . In some embodiments, one of the bottom surface 132 and the mounting area 116 b has a clamping portion 137 , and the other has a clamping slot 119 . The clamping portion 137 is clamped with the clamping slot 119 .

[0148] One of the bottom surface 132 and the mounting area 116b is provided with a holding portion 137, and the other is provided with a holding groove 119. Alternatively, the holding portion 137 may be provided on the bottom surface 132, and the holding groove 119 may be provided on the mounting area 116b. Alternatively, the holding groove 119 may be provided on the bottom surface 132, and the mounting area 116b, as long as the holding portion 137 and the holding groove 119 are engaged.

[0149] The lifting rib 130 is fixed to the installation area 116b by clamping the clamping portion 137 and the clamping groove 119. During the assembly process, the clamping portion 137 can play a certain guiding role, which can facilitate the assembly of the lifting rib 130 on the inner cylinder 100. After the clamping portion 137 and the clamping groove 119 are clamped, they can provide a certain positioning and fixing effect for the lifting rib 130.

[0150] In some embodiments, under the condition that a clamping groove 119 is set in the installation area 116b, the clamping groove 119 has a first groove section 119a and a second groove section 119b that are connected, the width of the first groove section 119a is greater than the width of the second groove section 119b, the second groove section 119b is clamped with the clamping portion 137, and the first groove section 119a is connected to the water outlet cavity 136 of the lifting rib 130.

[0151] During assembly, the retaining portion 137 is first inserted into the first groove section 119a and then slid toward the second groove section 119b, causing the retaining portion 137 to engage with the second groove section 119b. Furthermore, due to the greater width of the first groove section 119a, the first groove section 119a can also serve as a water outlet, draining water from the water outlet chamber 136 out of the inner cylinder 100.

[0152] Referring to Figures 6 and 3 , in some embodiments, the inner cylinder 100 further includes a fixing member. The mounting area 116b is provided with a first fixing hole 116c, and the bottom surface 132 is provided with a second fixing hole 138. The fixing member securely connects the first fixing hole 116c and the second fixing hole 138. After the retaining portion 137 and the retaining groove 119 are engaged, the fixing member passes through the first fixing hole 116c and the second fixing hole 138, thereby securing the lifting rib 130 to the cylinder body 110. Through the engagement of the retaining groove 119 with the retaining portion 137, and the engagement of the fixing member with the first fixing hole 116c and the second fixing hole 138, a dual securing effect is achieved, effectively securing the lifting rib 130.

[0153] In some embodiments, the drum member further includes a stator mounting assembly. This stator mounting assembly can be applied to a clothing processing device, such as a washing machine, a dryer, or a washer-dryer-in-one. It should be noted that this stator mounting assembly can also be applied to other equipment requiring a motor, such as air conditioners and floor scrubbers, without limitation.

[0154] 8-13 , a stator mounting assembly according to some embodiments of the present disclosure includes a base 1, a bearing housing 2, and a stator 3. The bearing housing 2 is assembled on the base 1, which is provided with a first positioning member a. The stator 3 is assembled on the base 1, which is provided with a second positioning member b. The second positioning member b cooperates with the first positioning member a (as shown in FIG. 14 ) to position the stator 3 on the base 1.

[0155] In some embodiments, since the stator mounting assembly has the first positioning member a for positioning the stator disposed on the base, there is no need to provide a positioning member for positioning the stator on the bearing seat. This not only simplifies the structure of the bearing seat, reduces the manufacturing difficulty and reduces the manufacturing links, thereby reducing the processing difficulty and simplifying the processing technology, but also reduces the volume of the bearing seat to achieve the technical purpose of reducing manufacturing costs and improving practicality.

[0156] 8-13 , in some embodiments, the first positioning member a may include a first coarse positioning member a1, and the second positioning member b may include a second coarse positioning member b1, and the second coarse positioning member b1 cooperates with the first coarse positioning member a1 (as shown in FIG. 14 ) to pre-position the stator 3 on the base 1 .

[0157] 8-13 , in some embodiments, the first positioning member a may further include a first precision positioning member a2 , and the second positioning member b may further include a second precision positioning member b2 , and the second precision positioning member b2 cooperates with the first precision positioning member a2 to assemble the stator 3 on the base 1 .

[0158] In the embodiment of the present disclosure, one of the first coarse positioning member a1 and the second coarse positioning member b1 is a positioning protrusion, and the other is a positioning recess provided on the assembly surface of the stator 3 or the base 1 and cooperating with the positioning protrusion, that is, the stator 3 is pre-positioned on the base 1 by assembling the positioning protrusion into the corresponding positioning recess, and the positioning recess can be a positioning groove, a positioning notch or a positioning hole, etc.

[0159] In some embodiments, the first coarse positioning member a1 can be a positioning protrusion, and the second coarse positioning member b1 can be a positioning depression. When the positioning protrusion is assembled into the corresponding positioning depression, the stator 3 can be suspended on the base 1. In some embodiments, the first coarse positioning member a1 can be disposed on the upper portion of the base 1, above the bearing seat 2, so that the positioning depression of the stator 3 is suspended on the positioning protrusion located on the upper portion of the base 1, thereby suspending the stator 3 on the base 1. In other embodiments, the first coarse positioning member a1 can be a positioning depression, and the second coarse positioning member b1 can be a positioning protrusion.

[0160] In the disclosed embodiment, one of the first and second precision positioning members a2 and b2 is a positioning post, and the other is a positioning hole provided on the assembly surface of the stator 3 or the base 1 and cooperating with the positioning post. Specifically, the stator 3 is precisely positioned on the base 1 by fitting the positioning post into the corresponding positioning hole.

[0161] In some embodiments, the first precision positioning member a2 may be a positioning hole provided on the assembly surface of the base 1, and the second precision positioning member b may be a positioning post provided on the stator 3. During assembly, the stator 3 may be pushed and assembled into the corresponding positioning hole to precisely position the stator 3 on the base 1. In some embodiments, at least two first precision positioning members a2 may be provided around the mounting portion of the base 1, and at least two corresponding second precision positioning members b2 may be provided. By means of a plurality of mutually cooperating first precision positioning members a2 and second precision positioning members, precise positioning of the stator 3 on the base 1 is achieved, facilitating the subsequent fixed assembly of the stator 3 on the base 1.

[0162] In other embodiments, the first precise positioning member a2 can be a positioning column arranged on the assembly surface of the base 1, and the second positioning member b can be a positioning hole arranged on the stator 3. During assembly, the positioning column can be assembled in the corresponding positioning hole by pushing the stator 3 so that the stator 3 is precisely positioned on the base 1.

[0163] The cross-sectional dimension of the first fine positioning member a2 is smaller than that of the first coarse positioning member a1. Correspondingly, the cross-sectional dimension of the second fine positioning member b2 is also smaller than that of the second coarse positioning member b1. When the second coarse positioning member b1 and the first coarse positioning member a1 cooperate with each other, the coarse positioning member with the larger cross-sectional dimension can support the stator 3 to pre-position the stator 3 on the assembly surface of the base 1, so as to facilitate the mutual cooperation of the fine positioning members with the smaller cross-sectional dimension and to facilitate the assembly of the stator 3.

[0164] Therefore, through the cooperation between the second positioning member b and the first positioning member a, the problem of axial and circumferential positioning of the stator during the assembly process is well solved, thereby improving practicality.

[0165] In the disclosed embodiment, during stator assembly, the second coarse locating member b1 and the first coarse locating member a1 engage before the second fine locating member b2 and the first fine locating member a2 engage. This allows the user to temporarily hang the stator 3 / motor on the base 1 during assembly, alleviating the lifting burden and allowing the user to focus on aligning and accurately positioning the fine locating members. In some embodiments, the first coarse positioning piece a1 can protrude from the first fine positioning piece a2 in the assembly direction of the stator 3. When assembling the stator 3, the second coarse positioning piece b1 on the stator 3 first cooperates with the supporting end of the first coarse positioning piece a1 on the base 1, so that the stator 3 / motor is temporarily hung on the first coarse positioning piece a1 on the base 1 to form a support, and the stator 3 is continued to be pushed, the second coarse positioning piece b1 on the stator 3 cooperates with the first coarse positioning piece a1 on the base 1, and the second fine positioning piece b2 on the stator 3 cooperates with the first fine positioning piece a2 on the base to position the stator on the base.

[0166] Based on the above design ideas, the present disclosure further describes the structures of the base 1 and the stator 3.

[0167] Referring to Figures 10-14 , the base 1 is provided with a first protrusion 11 that protrudes from the assembly surface of the base 1, and a first coarse locating member a1 is disposed on the outer circumferential surface of the first protrusion 11. Accordingly, the stator 3 is provided with a receiving opening 33 at one end facing the base 1, the first protrusion 11 being mounted within the receiving opening 33, and a second coarse locating member b1 being disposed on the peripheral wall of the receiving opening 33. To assemble the stator 3, the receiving opening 33 of the stator 3 is mounted on the first protrusion 11 of the base 1. The stator 3 is then pushed forward, engaging the first coarse locating member a1 and the second coarse locating member b1, thereby pre-positioning the stator 3 on the assembly surface of the base 1 and suspending the stator 3 on the first protrusion 11.

[0168] In conjunction with Figures 10-14, the first coarse positioning member a1 can be a positioning protrusion protruding from the outer circumference of the first protruding portion 11, and the second coarse positioning member b1 can be a positioning hole provided on the peripheral wall of the accommodating opening 33. The positioning protrusion can be loosely matched with the positioning hole to allow the stator 3 to move on the first protruding portion 11. In some embodiments, the first coarse positioning member a1 can be provided at the top of the first protruding portion 11, extending along the generatrix direction of the first protruding portion 11 on the outer circumference of the first protruding portion 11; in other embodiments, since the stator 3 is suspended on the first protruding portion 11, the first coarse positioning member a1 can also be provided at the bottom or side of the first protruding portion 11, without limitation herein.

[0169] 10-14 , the base body 1 is provided with a first receiving groove 12. The first coarse positioning member a1 protrudes out of the first receiving groove 12 toward the end of the stator 3. The first coarse positioning member a1 extends away from the end of the stator 3 to the bottom of the first receiving groove 12. When the stator 3 is assembled, the positioning hole on the stator 3 is mounted on the part of the first coarse positioning member a1 that protrudes out of the first receiving groove 12.

[0170] In conjunction with Figures 10, 11 and 14, there may be a gap between the top of the first coarse locating member a1 and the side wall of the first accommodating groove 12, and the first coarse locating member a1 may be in a T-shaped structure or a cross-shaped structure. Under the condition that a coarse locating member is in a cross-shaped structure, a guide slope is provided at the top of the cross-shaped structure toward the end of the stator 3 to guide the locating hole on the stator 3 when assembled on the cross-shaped structure, thereby improving practicality. The second coarse locating member b1 is roughly a rectangular notch, thereby allowing the stator 3 to have a relatively large amount of precise positioning adjustment space (such as swing amplitude) relative to the base 1. In addition, the first coarse locating member a1 of the cross-shaped structure is in point contact with the wall of the second coarse locating member b1, which is conducive to reducing friction and facilitating assembly advancement. In some embodiments, the second coarse locating member b1 can also be a cross-shaped notch that is compatible with the cross-shaped structure of the first coarse locating member a1, and the two are clearance-matched.

[0171] In other embodiments, the first coarse positioning member a1 may be a positioning hole provided on the outer peripheral surface of the first protruding portion 11 , and the second coarse positioning member b1 may be a positioning protrusion provided on the inner wall of the accommodating opening 33 .

[0172] 12 , the stator 3 is provided with a second protruding portion 31 protruding from the assembly surface of the stator, and the accommodating opening 33 is opened on the second protruding portion 31 .

[0173] In conjunction with Figures 10 to 13 and 15, the first precision positioning member a2 is provided on the assembly surface of the base 1, and the first precision positioning member a2 is provided on the outer side of the circumference of the first protrusion 11. An assembly portion 32 is provided at one end of the stator 3 facing the base 1. The assembly portion 32 may be the end of the second protrusion 31 facing the base 1. An accommodating opening 33 is provided in the middle of the assembly portion 32, and the assembly portion 32 may be configured as the assembly surface of the stator. After the stator 3 is assembled on the base 1, the assembly portion 32 of the stator 3 rests on the assembly surface of the base 1, and the second precision positioning member b2 is provided on the assembly portion 32. The second precision positioning member b2 cooperates with the first precision positioning member a2 to accurately assemble the stator 3 on the assembly surface of the base 1.

[0174] In conjunction with Figures 10 to 13 and 15, in some embodiments, the first fine positioning member a2 can be a positioning hole provided on the assembly surface of the base 1. The second fine positioning member b2 is a positioning column provided on the assembly portion 32. The positioning column is inserted into the positioning column in the positioning hole in a matching manner. When the stator 3 is assembled, the receiving opening 33 of the stator 3 is assembled on the first protrusion 11 of the base 1, and then the stator 3 is pushed. In this way, the first coarse positioning member a1 and the second coarse positioning member b1 can be assembled and matched, and the positioning column is inserted into the corresponding positioning hole, so that the stator 3 can be pre-positioned and precisely positioned on the assembly surface of the base 1 to improve practicality.

[0175] In conjunction with Figures 10 and 11, a second receiving groove 13 is provided on the base 1. A support column 14 is provided in the second receiving groove 13. The two ends of the support column 14 can be flush with the two ends of the second receiving groove 13. The positioning hole is provided on the end of the support column 14 facing the stator 3. The circumferential surface of the support column 14 can be connected to the inner wall of the second receiving groove 13 by one or more reinforcing ribs 15 to increase the strength of the support column 14 and improve the assembly effect on the stator 3. In some embodiments, reinforcing ribs 15 can be provided on opposite sides of the support column 14 to evenly increase the strength of the support column 14.

[0176] 10 and 11 , a coaxial first ring body 16 and a second ring body 17 are provided on the base 1. The first ring body 16 is provided inside the second ring body 17. The first ring body 16 protrudes from the second ring body 17 toward one end of the stator 3 to form the outer periphery of the above-mentioned first protruding portion 11. A plurality of connecting portions 18 are provided between the first ring body 16 and the second ring body 17. Each connecting portion 18 can be radially connected between the first ring body 16 and the second ring body 17. The plurality of connecting portions 18 are arranged around the outer periphery of the first protruding portion, wherein the space between two adjacent connecting portions 18 is configured as a first receiving groove 12, and the space between the remaining two adjacent connecting portions 18 is configured as a second receiving groove 13. The above-mentioned support columns 14 can be provided only in part of the second receiving grooves 13, and the number of support columns 14 is provided to be two or more. Correspondingly, more than two positioning holes are spaced around the central axis of the first protrusion 11, and more than two positioning columns are correspondingly provided, so that the stator 3 can be temporarily fixed on the base 1, facilitating the subsequent fixed assembly of the stator 3 on the base 1.

[0177] 10-13 , at least a portion of the connecting portion 18 is provided with a first mounting hole 19, and the second protruding portion 31 of the stator 3 is provided with a second mounting hole 34 corresponding to the first mounting hole 19. If the strength and other parameters of the base 1 meet the connection requirements, the first mounting hole 19 of the connecting portion 18 and the second mounting hole 34 of the second protruding portion 31 can be connected by a connecting member, which can be a bolt, to securely mount the stator 3 on the base 1.

[0178] Figure 16 shows a schematic structural diagram of the bearing seat in Figure 8. In conjunction with Figure 16, if the strength and other parameter conditions of the base 1 do not meet the connection requirements, a plurality of connecting columns 22 can be spaced apart and connected on the circumference of the main body 21 of the bearing seat 2. The connecting columns 22 can be made of the same material as the bearing seat 2, and the two can be formed as one piece. The connecting columns 22 and the connecting portion 18 are provided in correspondence, and the connecting columns 22 are inserted into the corresponding connecting portion 18. At least part of the connecting columns 22 is provided with the above-mentioned first mounting holes 19. In this way, the first mounting hole 19 on the connecting column 22 and the second mounting hole 34 of the second protrusion 31 can be connected through a connector so that the stator 3 is fixedly assembled on the base 1, thereby realizing the fixed assembly of the stator 3 on the base 1.

[0179] Combined with Figure 16, the connecting column 22 and the circumferential surface of the bearing seat 2 can be connected by a connecting block 23. The connecting column 22, the connecting block 23 and the bearing seat 2 can be formed as one piece. The connecting column 22, the connecting block 23 and the circumferential surface of the bearing seat 2 form a concave bottom structure for assembling the above-mentioned first ring body 16.

[0180] In some embodiments, the first mounting hole 19 can be spaced apart from the first precision positioning member a2 so that the stator is evenly stressed during assembly, thereby improving the firmness of the stator assembly.

[0181] In conjunction with Figures 8 to 11, in some embodiments, there is a clearance distance between the end of one of the connecting portions 18 facing the stator 3 and the end of the first protrusion 11 facing the stator 3, and a clearance groove 110 is provided on the end of the second ring body 17 connected to the connecting portion 18 facing the stator 3, so that the lead 6 connected to the coil on the stator 3 rests on the connecting portion 18 and is led out through the clearance groove 110, thereby preventing the lead 6 from loosening due to vibration of the equipment to a certain extent. In some embodiments, the connecting portion 18 provided with the clearance groove 110 is preferably located below the first protrusion 11 to lead the lead out from the lower part of the base 1. In other embodiments, the dividing portion provided with the clearance groove 110 can also be provided on the side of the first protrusion 11, which is not limited here.

[0182] 10 , 11 and 15 , the positioning post may be integrally formed on the assembly portion 32 of the stator 3 , and a guide curved surface is provided at the top end of the positioning post to allow the positioning post to be smoothly inserted into the corresponding positioning hole.

[0183] In other embodiments, the first precise positioning member a2 may be a positioning column provided on the assembly surface of the base 1 , and the second precise positioning member b2 may be a positioning hole provided on the assembly portion 32 .

[0184] In some embodiments, the bearing seat 2 can be integrally formed on the base 1. The bearing seat 2 can be made of metal. The base 1 can be made of plastic. The bearing seat 2 is integrally formed on the base 1 using an injection molding process. Because the positioning members and mounting holes for assembling the stator 3 are both provided on the plastic base 1, the manufacturing difficulty and cost of the bearing seat 2 can be reduced, while improving its practicality.
