For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The inner drum of conventional fabric handling equipment is made of stainless steel with many through holes on its surface. These through holes have burrs and sharp edges, which significantly increase the risk of fabric scuffing during washing. The technical problem of these holes scuffing fabric is usually addressed by polishing the through holes to make them smoother, but this method still cannot eliminate the presence of burrs and other structural elements.

[0023] Based on this, the following embodiments are proposed.

[0024] Example 1: like Figure 1-3 As shown in Figures 7 and 8, this embodiment provides a fabric processing device, including: an inner cylinder 1; and a lifting rib 2. The lifting rib 2 is disposed on the inner side wall of the inner cylinder 1. The lifting rib 2 has a side wall, and a bend area is formed between the side wall and the circumferential wall of the inner cylinder 1. A through hole 101 is provided only at the bend area on the circumferential wall of the inner cylinder 1.

[0025] In this embodiment, the sidewall preferably includes a first sidewall 201 and a second sidewall 202 located on opposite sides of the lifting rib 2. The corner area includes a first corner area 203 and a second corner area 204. The first corner area 203 is formed between the first sidewall 201 and the circumferential wall of the inner cylinder 1, and the second corner area 204 is formed between the second sidewall 202 and the circumferential wall of the inner cylinder 1. The through hole 101 is only opened in the first corner area 203 and / or the second corner area 204 on the circumferential wall of the inner cylinder 1.

[0026] In this embodiment, the inner cylinder 1 is an almost perforated inner cylinder 1, capable of rotating clockwise or counterclockwise, and the rotation speed of the inner cylinder 1 can be indirectly controlled by a computer board program controlling the drive motor. The two side walls of the lifting rib 2 and the inner side wall of the inner cylinder 1 respectively form a first angle region 203 and a second angle region 204 located on both sides of the lifting rib 2, and through holes 101 are only opened in the inner cylinder 1 at the first angle region 203 and the second angle region 204, while no through holes 101 are opened in other large areas of the inner side wall of the inner cylinder 1.

[0027] When the fabric handling equipment is running during the washing process, the rotation of the inner drum 1 causes the lifting ribs 2 to come into contact with the fabric. The lifting ribs 2 lift the fabric while simultaneously rubbing against it, thus cleaning stains. During this process, because the sidewalls of the lifting ribs 2 protrude from the inner wall of the inner drum 1, an angle is formed between them. Therefore, the angled area formed between the sidewalls of the lifting ribs 2 and the inner wall of the inner drum 1 constitutes an angled region. The through holes 101 located in the first angled region 203 and the second angled region 204 are actually hidden within this angled region. Water can flow out of the inner drum 1 through the through holes 101 within this angled region, preventing bacteria growth and odors caused by residual washing water in the angled region. At other locations on the inner wall of the inner drum 1... Instead of providing through holes 101, the through holes 101 on the inner cylinder 1 are hidden within the included angle θ region. This also ensures that when the fabric rubs against the lifting rib 2, it will not come into contact with the through holes 101 at other locations on the inner sidewall of the inner cylinder 1, nor will it come into contact with the through holes 101 located within the included angle region. This reduces the friction between the fabric and the through holes 101 on the inner cylinder 1, greatly reducing the wear and tear on the fabric caused by the through holes 101. Furthermore, the reduction in the number of through holes 101 on the inner cylinder 1 can also improve the structural strength of the inner cylinder 1 and reduce the risk of deformation of the inner cylinder 1 during long-term use.

[0028] When the fabric processing equipment is running during the dewatering process, the inner cylinder 1 rotates at high speed. Under the action of centrifugal force, the fabric simultaneously presses against the lifting ribs 2 and the inner wall of the inner cylinder 1. At this time, the water on the fabric flows towards the through hole 101. Since the inner wall of the inner cylinder 1 and the side wall of the lifting ribs 2 are located on both sides of the through hole 101, and the opening of the angle area formed by the inner wall of the inner cylinder 1 and the side wall of the lifting ribs 2 gradually narrows from away from the through hole 101 to close to the through hole 101, the through hole 101 is in a wedge-shaped water storage area. After being blocked by the side wall of the lifting ribs 2, the water flows smoothly into the angle area, i.e., the wedge-shaped water storage area. In the angle area, the water pressure and its flow velocity gradually increase. When the water flows through the through hole 101, the flow velocity reaches its maximum. This ensures the drainage efficiency of the inner cylinder 1 even if the through hole 101 is only opened at the angle area, by increasing the water flow velocity at the through hole 101 in the angle area.

[0029] By opening through holes 101 only in the corner area formed by the inner wall of the inner drum 1 and the two side walls of the lifting rib 2, the occurrence of bacteria growth and odor caused by residual washing water in the corner area can be avoided. The water flow rate of the through holes 101 in the corner area can be increased to ensure the drainage efficiency of the inner drum 1. Furthermore, the wear and damage to the fabric caused by the through holes 101 can be reduced by reducing the friction between the fabric and the through holes 101 of the inner drum 1, thereby improving the washing effect on the fabric. The reduction of through holes 101 on the inner drum 1 can also improve the structural strength of the inner drum 1 and reduce the risk of deformation of the inner drum 1 during long-term use.

[0030] Optionally, such as Figure 1 , 2 As shown, in one implementation of this embodiment, the lifting rib 2 has a cavity 205; the first bend area 203 includes a first outer bend area 2031, which is located in the area outside the cavity 205 formed between the first side wall 201 and the circumferential wall of the inner cylinder 1, and the first outer bend area 2031 is provided with a plurality of through holes 101, which are spaced apart along the axial direction of the inner cylinder 1; and / or, the second bend area 204 includes a second outer bend area 2041, which is located in the area outside the cavity 205 formed between the second side wall 202 and the circumferential wall of the inner cylinder 1, and the second outer bend area 2041 is provided with a plurality of through holes 101, which are spaced apart along the axial direction of the inner cylinder 1.

[0031] Preferred, such as Figure 2 As shown, the first outer corner region 2031 has a first edge and a second edge opposite to each other along the circumferential wall of the inner cylinder 1. The first edge is designed as the bottom edge of the first side wall 201, and the distance L1 between the second edge and the first edge along the arc surface of the circumferential wall of the inner cylinder 1 is at least 5 mm; and / or, the second outer corner region 2041 has a first edge and a second edge opposite to each other along the circumferential wall of the inner cylinder 1. The first edge is designed as the bottom edge of the first side wall 201, and the distance L2 between the second edge and the first edge along the arc surface of the circumferential wall of the inner cylinder 1 is at least 5 mm.

[0032] In this embodiment, the first sidewall 201 and the second sidewall 202 of the lifting rib 2, together with the inner sidewall of the inner cylinder 1, enclose a cavity 205. The first outer corner area 2031 and the second outer corner area 2041 are both located outside the cavity 205. Multiple through holes 101 at the first outer corner area 2031 and the second outer corner area 2041 are linearly spaced, ensuring that the multiple through holes 101 are evenly distributed at the first outer corner area 2031 and the second outer corner area 2041. The multiple through holes 101 are used to drain the washing water from the fabric during the dewatering process of the inner cylinder 1. When water flows and impacts the lifting rib 2, a portion of the water in the inner cylinder 1 will first rush towards the first outer corner area 2031 or the second outer corner area 2041 and pass through the through holes 101 to exit the inner cylinder 1. This reduces the impact force on the lifting rib 2 and extends its service life.

[0033] Multiple through holes 101 are arranged at intervals along the axial direction of the inner cylinder 1, including at least two cases: when the side of the bottom of the lifting rib 2 is straight and parallel to the axis of the inner cylinder 1, the distance between each through hole 101 and the side of the bottom of the lifting rib 2 is equal, and the straight line formed by the multiple through holes 101 is also parallel to the axis of the inner cylinder 1; when the side of the bottom of the lifting rib 2 is curved, the distance between each through hole 101 and the side of the bottom of the lifting rib 2 is equal, and the multiple through holes 101 are also distributed in a curved manner. Although the curve formed by the side and the multiple through holes 101 is not parallel to the axis of the inner cylinder 1, the multiple through holes 101 are also extending from the bottom wall of the inner cylinder 1 away from the bottom wall of the inner cylinder 1 on the side wall of the inner cylinder 1. Therefore, these multiple through holes 101 can also be regarded as being arranged at intervals along the axial direction of the inner cylinder 1. In both of the above scenarios, the water flowing towards the first outer corner zone 2031 or the second outer corner zone 2041 can simultaneously contact each through hole 101 and be directly discharged from the inner cylinder 1 through the through hole 101. This design shortens the path of the water flow to the through hole 101, so that the water flow does not have to accumulate and wait due to the long path during the discharge process, thereby reducing the time for the water flow to discharge from the inner cylinder 1 and improving the drainage efficiency of the inner cylinder 1.

[0034] By setting the first outer corner area 2031 and the second outer corner area 2041 outside the cavity 205 respectively, and arranging multiple through holes 101 at intervals along the axial direction of the inner cylinder 1, the impact force on the lifting rib 2 can be reduced, the service life of the lifting rib 2 can be extended, and the time for water to flow out of the inner cylinder 1 can be reduced, thereby improving the drainage efficiency of the inner cylinder 1.

[0035] Optionally, such as Figure 7 , 8As shown, in one implementation of this embodiment, the first angle region 203 includes a first inner angle region 2032, which is located in the region inside the cavity 205 formed between the first side wall 201 and the circumferential wall of the inner cylinder 1. The first inner angle region 2032 is provided with a plurality of through holes 101, which are spaced apart along the axial direction of the inner cylinder 1; and / or, the second angle region 204 includes a second inner angle region 2042, which is located in the region inside the cavity 205 formed between the second side wall 202 and the circumferential wall of the inner cylinder 1. The second inner angle region 2042 is provided with a plurality of through holes 101, which are spaced apart along the axial direction of the inner cylinder 1.

[0036] In this embodiment, the first inner bend area 2032 and the second inner bend area 2042 are both located inside the cavity 205, and are formed by the inner surface of the first sidewall 201 and the inner surface of the second sidewall 202, respectively, together with the inner sidewall of the inner cylinder 1 located inside the cavity 205. Multiple through holes 101 are also provided in both the first inner bend area 2032 and the second inner bend area 2042. These through holes 101 can be arranged directly below the cavity 205 of the lifting rib 2 to drain the washing water entering the cavity 205 between the inner cylinder 1 and the outer cylinder 3, thereby being drained away. The openings of the bend areas formed by the inner sidewall of the inner cylinder 1 and the inner surfaces of the first sidewall 201 and the second sidewall 202 gradually narrow from away from the multiple through holes 101 to close to them, thus placing the multiple through holes 101 within a wedge-shaped water storage area.

[0037] Multiple through holes 101 located inside the cavity 205 are arranged at intervals along the axial direction of the inner cylinder 1. This includes at least two cases: when the side of the bottom of the lifting rib 2 is straight and parallel to the axis of the inner cylinder 1, the distance between each through hole 101 and the side of the bottom of the lifting rib 2 is equal, and the straight line formed by the multiple through holes 101 is also parallel to the axis of the inner cylinder 1; when the side of the bottom of the lifting rib 2 is curved, the distance between each through hole 101 and the side of the bottom of the lifting rib 2 is equal, and the multiple through holes 101 are also distributed in a curved manner. Although the curve formed by the side and the multiple through holes 101 is not parallel to the axis of the inner cylinder 1, the multiple through holes 101 are also extended from the bottom wall of the inner cylinder 1 away from the bottom wall of the inner cylinder 1 on the side wall of the inner cylinder 1. Therefore, these multiple through holes 101 can also be regarded as being arranged at intervals along the axial direction of the inner cylinder 1. In both of the above scenarios, the water flow inside the lifting rib 2 can simultaneously contact each through hole 101 and be directly discharged from the inner cylinder 1 through the through holes 101. When the inner cylinder 1 rotates, the water flow, after being blocked by the side wall of the lifting rib 2, will smoothly flow into the corner area, i.e., the wedge-shaped water storage area. In the corner area, the water pressure will gradually increase. When the water flows into the corner area, its pressure will gradually increase, and its flow velocity will also gradually increase. When the water flows through the through hole 101, the flow velocity reaches its maximum. This ensures that even if the inner cylinder 1 only has the through holes 101 at the corner area, by increasing the water flow velocity at the through holes 101 in the corner area, the drainage efficiency of the inner cylinder 1 can still be guaranteed.

[0038] By setting the first inner folding area 2032 and the second inner folding area 2042 outside the cavity 205, and setting multiple through holes 101 in the cavity 205 at intervals along the axial direction of the inner cylinder 1, the fabric will not come into contact with the newly added through holes 101, thus increasing wear, and the number of through holes 101 in the inner cylinder 1 is increased, thereby improving the drainage efficiency of the inner cylinder 1.

[0039] Optionally, such as Figure 1-3 As shown, in one implementation of this embodiment, the plurality of through holes 101 located in the first outer corner region 2031 and the plurality of through holes 101 located in the second outer corner region 2041 are all dewatering holes, and the plurality of through holes 101 located in the first inner corner region 2032 and the plurality of through holes 101 located in the second inner corner region 2042 are all designed as drainage holes, wherein the diameter of the drainage holes is larger than the diameter of the dewatering holes.

[0040] In this embodiment, all dewatering holes are located on the outside of the lifting rib 2. This allows the dewatering holes to come into contact with the water flow immediately. Before the water flow impacts the lifting rib 2, a portion of the water flow is guided through the dewatering holes and out of the inner cylinder 1, thereby reducing the water flow impact force on the lifting rib 2 and extending its service life. The drain holes are located inside the cavity 205 of the lifting rib 2, and their diameter is larger than that of the dewatering holes. This allows the water flow within the confined space of the cavity 205 to be quickly discharged outwards, reducing the risk of backflow caused by excessive water pressure within the cavity 205 of the lifting rib 2, and minimizing the possibility of lint and impurities in the water flowing back into the inner cylinder 1.

[0041] By setting the diameter of the drain hole located inside the cavity 205 to be larger than the diameter of the dewatering hole located outside the cavity 205, the water flow impact force borne by the lifting rib 2 can be reduced, the service life of the lifting rib 2 can be extended, and the risk of backflow caused by excessive water flow pressure inside the cavity 205 of the lifting rib 2 can be reduced, as well as the occurrence of lint and impurities in the water flowing back into the inner drum 1, thereby further improving the washing effect on the fabric.

[0042] Optionally, such as Figure 7 , 8 As shown, in one implementation of this embodiment, a first flow hole 2011 is provided on the first sidewall 201 at a distance, and the first flow hole 2011 is connected to the cavity 205. A second flow hole 2021 is provided on the second sidewall 202 at a distance, and the second flow hole 2021 is connected to the cavity 205. The diameters of both the first flow hole 2011 and the second flow hole 2021 are designed to gradually increase from the inside to the outside of the cavity 205.

[0043] In this embodiment, the first flow hole 2011 and the second flow hole 2021 are both elongated trumpet-shaped through holes 101 and are evenly distributed on the first sidewall 201 and the second sidewall 202, respectively. The first flow hole 2011 and the second flow hole 2021 are both designed such that the inner diameter of the opening facing the outside of the lifting rib 2 is larger than the inner diameter of the tail opening facing the inside of the lifting rib 2, and the inner diameter of the elongated trumpet-shaped through hole 101 gradually increases from the inside of the cavity 205 to the outside, so that the water flow can more effectively carry the lint and impurities into the lifting rib 2 during the washing process. The ratio of the inlet cross-section of the first sidewall 201 and the second sidewall 202 to the inlet cross-section of the first flow hole 2011 and the second flow hole 2021 is optimized to 1.2:1, thereby maximizing the flow velocity gradient. When the inner cylinder 1 rotates, the water carrying lint and impurities enters the interior of the lifting rib 2 through the first flow hole 2011 or the second flow hole 2021 on the surface of the lifting rib 2 under the propulsion of centrifugal force. The opening end face of the first flow hole 2011 and the second flow hole 2021 is the positive end face, and the tail end face is the reverse end face. Since the inner diameter of the positive end face is larger than the size of the lint, the water and lint and impurities can pass through the positive end face smoothly and easily. However, when the water and lint and impurities flow from the narrow reverse end face to the outside of the lifting rib 2, it is difficult for them to flow back into the inner cylinder 1 through the first flow hole 2011 or the second flow hole 2021.

[0044] At the positive end face, the dynamic interaction between the lint and water flow, due to the balance of inertia and viscosity, as well as inelastic deformation, creates a physical barrier for unidirectional flow, guiding the lint and impurities into the lifting rib 2 during the forward flow of water. At the reverse end face, the water flow velocity within the lifting rib 2 decreases significantly as it flows outward. Since the inner diameter of the reverse end face is almost identical to the size of the lint and impurities, the lint and impurities cannot deform and pass through the reverse end face, becoming permanently stuck in the cavity 205. Because the lint and impurities are larger than the inner diameter of the tail opening, they are trapped and retained within the lifting rib 2 by the elongated trumpet-shaped through-hole 101, preventing them from returning to the inner cylinder 1 with the water flow. This achieves the goal of making it easy for lint and impurities to enter but difficult to exit within the lifting rib 2.

[0045] The typical size of the lint is between 0.1 mm and 1.0 mm. Therefore, the aperture width of the first flow hole 2011 and the second flow hole 2021 on the side away from the cavity 205 can be set to 1.5 mm, and the aperture of the first flow hole 2011 and the second flow hole 2021 on the side close to the cavity 205 can be set to 0.5 mm.

[0046] By setting both the first flow hole 2011 and the second flow hole 2021 as elongated trumpet-shaped through holes 101, and evenly distributing them on the first side wall 201 and the second side wall 202 respectively, the lifting rib 2 forms a fluid channel with directional selectivity on both sides. The unidirectional conductivity of the fluid is used to absorb lint and impurities in the water flow and trap them in the lifting rib 2, preventing lint and impurities from flowing back into the inner cylinder 1 and causing re-contamination of the fabric. This allows lint and impurities to be discharged from the inner cylinder 1 more efficiently, thereby achieving a more thorough cleaning effect on the fabric.

[0047] Optionally, such as Figure 4-6 As shown, in one implementation of this embodiment, the fabric processing equipment further includes an outer cylinder 3 and a drying assembly. An inner cylinder 1 is disposed inside the outer cylinder 3, and an air hole 102 is provided on the bottom wall of the inner cylinder 1. An air cavity is formed between the bottom wall of the outer cylinder 3 and the bottom wall of the inner cylinder 1, and the air hole 102 is connected to the air cavity. The drying assembly includes a condensation section 301, a fan section 302, and a heating section 303. Both ends of the fan section 302 are connected to the condensation section 301 and the heating section 303, respectively. The inlet end of the condensation section 301 is connected to the air cavity, and the outlet end of the heating section 303 is connected to the inner cylinder 1.

[0048] In this embodiment, the outer cylinder 3 is mainly used to hold water, and a gap is left between it and the inner cylinder 1. The washing water can be discharged to the outside through the gap between the inner cylinder 1 and the outer cylinder 3. A part of this gap forms an air cavity. The condensation section 301, the fan section 302, and the heating section 303 are all fixed on the outer cylinder 3, which can generate drying air that circulates in the inner cylinder 1 to dry the dehydrated fabric.

[0049] The air vent 102 of the inner cylinder 1 is connected to the air cavity, which is located downstream of the air vent 102. The air cavity is connected to the inlet of the condensing section 301, which is located downstream of the air cavity. The outlet of the condensing section 301 is connected to the air inlet of the fan section 302, which is located downstream of the condensing section 301. The air outlet of the fan section 302 is connected to the inlet of the heating section 303, which is located downstream of the fan section 302. The outlet of the heating section 303 is connected to the inner cylinder 1, which is located downstream of the heating section 303. Thus, the inner cylinder 1, the outer cylinder 3, and the drying assembly together form a complete circulating drying air duct. The projection of the inlet of the condensing section 301 onto the inner cylinder 1 always falls within the area formed by the rotation of the air vent 102.

[0050] When the fabric processing equipment is running in drying mode, both the fan section 302 and the heating section 303 are started and begin to work, and the inner cylinder 1 will rotate continuously, evenly and slowly to turn the fabric over. Under the action of the fan, the ambient temperature and high humidity air in the inner cylinder 1 enters the air cavity through the air hole 102 and is rapidly cooled when it enters the condensation section 301, thereby separating the moisture from the ambient temperature and high humidity air and generating condensate. The condensate adheres to and accumulates on the inner wall of the condensation section 301. At this time, the moisture in the ambient temperature and high humidity air is greatly reduced, and its humidity and temperature drop significantly. The ambient temperature and high humidity air becomes low temperature and dry air. When the low temperature and dry air enters the heating section 303 through the fan, the air temperature is heated and rises rapidly. Therefore, high temperature and dry air will flow out from the outlet of the heating section 303. When the high temperature and dry air enters the inner cylinder 1, the moisture attached to the fabric is absorbed by the high temperature and dry air. At this time, the high temperature and dry air becomes ambient temperature and high humidity air again, and enters the air cavity through the air hole 102 to enter the next condensation-heating drying cycle. In this drying cycle, the moisture attached to the fabric becomes less and less until there is almost no residual moisture on the fabric. The drying operation of the fabric is completed, and the fabric processing equipment stops operating in drying mode.

[0051] By providing air holes 102 connected to the air chamber on the bottom wall of the inner drum 1, the inner drum 1, outer drum 3, and drying components together form a complete circulating drying air duct. The inner drum 1 gently tumbles the fabric to achieve drying, increasing the contact area between the fabric and the high-temperature dry air, thereby improving the drying efficiency of the fabric processing equipment. Lifting ribs 2 are installed on the inner drum 1. In conjunction with the drying components, they not only enable the fabric processing equipment to remove lint but also effectively reduce the risk of clothing being scratched, without compromising the strength of the inner drum 1 and preventing deformation after prolonged washing.

[0052] Preferably, the bottom wall of the inner cylinder 1 has multiple fan-shaped ventilation areas arranged in a ring, and the multiple air holes are opened in the fan-shaped ventilation areas. The projection of the inlet end of the condensation section 301 on the bottom wall of the inner cylinder 1 is located in the ventilation area, ensuring that the drying airflow resistance is small and the flow is smoother.

[0053] Optionally, such as Figure 7 , 8 As shown, in one implementation of this embodiment, the lifting rib 2 includes a support 206, which is disposed inside the cavity 205. The support 206 has multiple partition ribs, which divide the cavity 205 into multiple flow cavities 2061. At least some of the partition ribs have their ends abutting against the inner wall of the first side wall 201 and the inner wall of the second side wall 202, respectively.

[0054] In this embodiment, the two sides of the bracket 206 are a first side and a second side, respectively. The first side and the second side are positioned opposite to the first sidewall 201 and the second sidewall 202. At least some of the ends of the partitions abut against the inner walls of the first sidewall 201 and the second sidewall 202, so that the first sidewall 201 and the second sidewall 202 together with the partitions form a plurality of flow cavities 2061.

[0055] There are multiple first flow holes 2011 and second flow holes 2021, which are arranged in rows on the first sidewall 201 and the second sidewall 202, respectively. There are multiple flow cavities 2061, which are arranged at intervals inside the support 206. Each row of first flow holes 2011 or second flow holes 2021 corresponds to at least one flow cavity 2061. One end of each flow cavity 2061 is connected to the first flow hole 2011 or the second flow hole 2021, and the other end of each flow cavity 2061 is connected to the bottom of the lifting rib 2. In this way, a multi-level fluid channel can be formed inside the lifting rib 2. By using an independent flow channel system for each layer, the water flow path can be three-dimensionally divided, and the water flow can be dispersed into different levels of flow channels. This avoids the situation where the local flow velocity is too high or the pressure is concentrated in the cavity 205 inside the support 206, thereby reducing the impact force of the water flow. At the same time, it avoids the formation of convection and turbulence in the flow cavity 2061, and accelerates the drainage speed of the lifting rib 2.

[0056] By dividing the cavity 205 into multiple flow cavities 2061 by multiple baffles, the water flow pressure inside the lifting rib 2 can be reduced, and the water flow can be prevented from forming convection and turbulence in the cavity 205, thereby improving the drainage efficiency of the lifting rib 2.

[0057] Example 2 like Figure 9 As shown, this embodiment provides a control method for the fabric processing equipment in Embodiment 1, wherein the fabric processing equipment is a washing machine, and the method includes a lint removal washing process, wherein the lint removal washing process alternately runs a washing process and a dehydration process.

[0058] In this embodiment, when the fabric processing equipment is a washing machine without a drying function, the control method controls the fabric processing equipment to alternately run the washing process and the dehydration process. By washing first and then dehydrating, the fabric is cleaned and the residual moisture in the fabric is reduced so that the user can dry the fabric quickly.

[0059] Fabric treatment equipment can also perform lint removal and washing operations on fabrics, that is, remove lint and impurities from the fabrics during the washing process.

[0060] The control method first controls the fabric treatment equipment to perform a lint removal and washing process on the fabric. After the lint removal and washing process is completed, the fabric treatment equipment is controlled to run a dehydration process until the dehydration process is completed, and then the lint removal and washing process on the fabric is ended. At this time, the user can manually take out the fabric to dry.

[0061] Since this control method includes the fabric treatment equipment of Embodiment 1, it possesses all the beneficial effects of the fabric treatment equipment of Embodiment 1, which will not be elaborated upon here. Furthermore, by controlling the operating mode of the fabric treatment equipment of Embodiment 1, this control method achieves a better hair removal effect.

[0062] Example 3 like Figure 10 As shown, this embodiment provides a control method for a fabric processing device in Embodiment 1. The fabric processing device is a washer-dryer. The method includes a lint removal washing process, in which a washing process and a dehydration process are alternately operated. After the previous dehydration process ends and before the next washing process begins, the washer-dryer is controlled to operate a drying process.

[0063] Preferably, it is determined whether the moisture content of the fabric in the inner drum 1 is lower than the preset moisture content. If the moisture content of the fabric in the inner drum 1 is lower than the preset moisture content, the washer-dryer is controlled to stop the drying process and start the washing process.

[0064] In this embodiment, when the fabric treatment equipment is a washer-dryer equipped with a drying component and can operate in drying mode to dry the fabric, the fabric treatment equipment performs the following lint removal and washing operation on the fabric: The control method first controls the fabric treatment equipment to perform a lint removal and washing process on the fabric. After the lint removal and washing process is completed, the control method controls the fabric treatment equipment to run a dehydration process. After the dehydration process is completed, the control method controls the fabric treatment equipment to run a drying mode to dry the fabric. The drying mode can first blow away the lint that is not completely washed off the fabric surface, so that it falls on the fabric surface or into the inner drum 1. When the moisture content of the fabric is detected to be lower than 60%, the control method controls the fabric treatment equipment to stop running the drying mode and controls the fabric treatment equipment to perform the lint removal and washing process again. Through multiple lint removal and washing processes, the lint on the fabric is removed more thoroughly. Then the fabric treatment equipment continues to run the dehydration process until the dehydration is completed, and then the lint removal and washing process on the fabric ends. At this time, the user can choose to take out the fabric directly to air dry, or take out the fabric after drying.

[0065] After the fabric is dewatered, it will be repeatedly dried by the drying air circulation in the inner drum 1, so that the lint stuck to the fabric will be blown away. Through multiple lint removal and washing processes, the lint can be removed more thoroughly. Some of the lint will also enter the condenser section 301 and be washed away by the condensed water.

[0066] This control method combines the dehydration process, washing process, and drying mode, which can reduce the moisture content of the fabric while controlling the fabric treatment equipment to perform multiple lint removal and washing operations. This allows the fabric to be dried quickly after the lint removal and washing operations, thereby enhancing both the lint removal effect and the efficiency of the lint removal and washing process.

[0067] Example 4 This embodiment provides a control method for a fabric processing device according to Embodiment 1. When the fabric processing device is a washing machine, the method includes a first lint removal washing process, in which a first washing process and a first dehydration process are alternately run. When the fabric treatment equipment is a washer-dryer, the method includes a second lint removal washing process, in which a second washing process and a second dehydration process are alternately run, and after the previous second dehydration process ends and before the next second washing process begins, the washer-dryer is controlled to run a drying process. The runtime of the first washing process is longer than that of the second washing process.

[0068] In this embodiment, when the fabric processing equipment is a washing machine without a drying function, the fabric processing equipment cannot use the drying mode to assist in the removal of lint from the fabric. Instead, the removal of lint from the fabric is achieved by increasing the duration of the lint removal washing process and repeatedly changing the washing water.

[0069] When the fabric handling equipment is a washing machine without a drying function, the first washing process can be controlled to be around 30 minutes. When the fabric handling equipment is a washer-dryer with a drying component and can operate in drying mode to dry the fabric, the second washing process can be controlled to be around 15 minutes.

[0070] This control method can adjust the duration of the lint removal process to perform the lint removal process on the fabric in both cases where the fabric processing equipment has a drying function and one where it does not. This allows the fabric processing equipment to achieve good lint removal effect and energy consumption balance in both cases, thereby further improving the adaptability of the control method and greatly enhancing the user experience.

[0071] In summary, the ingenious design of the fabric processing equipment lies in: First, by opening through holes only in the corner area formed by the circumferential wall of the inner drum and the side walls of the lifting ribs, it is possible to avoid the growth of bacteria and the generation of odors due to residual washing water in the corner area. It also increases the water flow rate in the through holes in the corner area to ensure the drainage efficiency of the inner drum. Furthermore, it can reduce the wear and damage to the fabric caused by the through holes by reducing the friction between the fabric and the through holes of the inner drum, thereby improving the washing effect on the fabric. The reduction of through holes on the inner drum can also improve the structural strength of the inner drum and reduce the risk of deformation of the inner drum during long-term use.

[0072] Secondly, by setting the first and second outer corner areas outside the cavity respectively, and arranging multiple through holes at intervals along the axial direction of the inner cylinder, the impact force on the lifting ribs can be reduced, the service life of the lifting ribs can be extended, the time for water to drain out of the inner cylinder can be reduced, and the drainage efficiency of the inner cylinder can be improved.

[0073] Third, by setting the first inner folding area and the second inner folding area outside the cavity, and setting multiple through holes in the cavity and arranging them at intervals along the axis of the inner cylinder, the fabric will not come into contact with the newly added through holes, thus increasing wear, while increasing the number of through holes in the inner cylinder and improving the drainage efficiency of the inner cylinder.

[0074] Fourth, by setting the diameter of the drain hole located inside the cavity to be larger than the diameter of the dewatering hole located outside the cavity, the water flow impact force on the lifting ribs can be reduced, extending the service life of the lifting ribs. It can also reduce the risk of backflow caused by excessive water flow pressure inside the lifting rib cavity, and reduce the occurrence of lint and impurities in the water flowing back into the inner drum, thereby further improving the washing effect on the fabric.

[0075] Fifth, by setting both the first and second flow holes as elongated trumpet-shaped through holes and evenly distributing them on the first and second side walls respectively, the lifting ribs form directional fluid channels on both sides. The unidirectional conductivity of the fluid is used to absorb lint and impurities in the water flow and trap them in the lifting ribs, preventing lint and impurities from flowing back into the inner drum and causing re-contamination of the fabric. This allows lint and impurities to be discharged from the inner drum more efficiently, achieving a more thorough cleaning effect on the fabric.
