Description

Technical Field

[0001] This application relates to the field of washing machine technology, and more particularly to a pulsator washing machine. Background Technology

[0002] The current process of drying clothes in top-loading washing machines with drying functions is as follows: hot air is introduced into the inner drum, and the hot air flows through the wet clothes in the inner drum, taking away the moisture from the wet clothes and drying them in the inner drum.

[0003] Because wet clothes are usually stacked inside the drum, hot air can only flow over the surface of the clothes and cannot make sufficient contact with them, resulting in low drying efficiency. Therefore, related technologies incorporate a clothes-drying assembly inside the drum. This assembly hangs the wet clothes up, allowing the hot air to make full contact with them and improving drying efficiency.

[0004] However, the drying components of this technology occupy a large space in the inner drum, resulting in a decrease in the effective volume of the inner drum and a reduction in the processing capacity of the pulsator washing machine. Utility Model Content

[0005] This application discloses a pulsator washing machine that can increase the processing capacity of the pulsator washing machine.

[0006] To achieve the above objectives, embodiments of this application disclose a pulsator washing machine, comprising: Box; The outer cylinder is located inside the box. The inner cylinder is rotatably disposed inside the outer cylinder; The impeller is rotatably disposed at the bottom of the inner cylinder; A drying component is disposed inside the chamber, and the air outlet of the drying component is connected to the space inside the inner cylinder for supplying hot air to the inner cylinder. Clothes drying assembly, including: A support member is provided on the impeller; A clothes drying rack is located around the support member, and one end of the clothes drying rack is rotatably connected to the support member so that the clothes drying rack can be unfolded or retracted relative to the support member. When the clothes drying rack is unfolded relative to the support member, it is used to hang clothes; when the clothes drying rack is retracted relative to the support member, at least a portion of the clothes drying rack extends beyond the outer circumferential surface of the support member along the radial direction of the inner drum, so that the clothes drying rack agitates the washing water or clothes as it rotates with the impeller.

[0007] In this application, the clothes drying assembly includes a support and a clothes drying component. The clothes drying component is located around the support and one end of the clothes drying component is rotatably connected to the support so that the clothes drying component can be unfolded or retracted relative to the support.

[0008] When clothes need to be dried, the clothes drying rack can be unfolded relative to the support frame. At this time, the clothes drying rack can be used to hang clothes. Compared with the clothes being piled up in the inner drum, hanging the clothes on the clothes drying rack can increase the contact area between the clothes and the hot air in the inner drum, thereby allowing the hot air to fully contact the clothes and improving the drying efficiency.

[0009] When washing clothes, the clothes drying rack can be folded up relative to the support member. At this time, the end of the drying rack facing away from the support member is closer to it, thus reducing the overall size of the drying assembly and minimizing the space it occupies within the inner drum. This increases the effective volume of the inner drum and improves the processing capacity of the pulsator washing machine. Furthermore, when the drying rack is folded up relative to the support member, at least a portion of it extends beyond the outer circumference of the support member along the radial direction of the inner drum. This allows the drying rack to directly agitate the washing water or clothes in the inner drum as it rotates with the pulsator; in other words, the drying rack can function as an agitator, thereby improving the cleaning effect on clothes. Therefore, the drying rack of this application can be used for hanging clothes when unfolded and as an agitator when folded up to agitate the washing water or clothes in the inner drum, achieving a dual-purpose effect.

[0010] In one alternative embodiment, the clothes drying element has a first side surface distributed circumferentially along the inner cylinder, the first side surface including a first agitation surface, which extends radially beyond the outer circumferential surface of the support when the clothes drying element is retracted relative to the support. The ratio of the area of ​​the first stirring surface to the total area of ​​the first side surface is greater than or equal to 0.5.

[0011] If the ratio of the area of ​​the first agitation surface to the total area of ​​the first side surface is less than 0.5, then the portion of the clothes drying garment that extends beyond the outer periphery of the support member when it is folded up will be smaller, and the area of ​​the first agitation surface that extends beyond the outer periphery of the support member on the first side surface will be smaller. Obviously, this will weaken the agitation effect of the clothes drying garment on the washing water or clothes when it is folded up relative to the support member, thereby weakening the cleaning effect of the clothes drying garment on the clothes when it is folded up.

[0012] Therefore, in this embodiment, the ratio of the area of ​​the first agitation surface to the total area of ​​the first side surface is set to be greater than or equal to 0.5, so that when the clothes drying garment is folded up, a larger portion extends beyond the outer periphery of the support member. This results in a larger area of ​​the first agitation surface extending beyond the outer periphery of the support member on the first side surface, thereby ensuring the agitation effect of the clothes drying garment on the washing water or clothes when it is folded up relative to the support member, and thus ensuring the cleaning effect of the clothes drying garment on the clothes when it is folded up.

[0013] In one optional embodiment, the clothes drying rack has a first side surface and a second side surface distributed circumferentially along the inner cylinder, the first side surface including a first agitation surface extending radially beyond the outer circumferential surface of the support member along the inner cylinder, the second side surface including a second agitation surface extending radially beyond the outer circumferential surface of the support member along the inner cylinder, the clothes drying rack having a bearing surface for hanging clothes when it is unfolded relative to the support member, and a third side surface disposed opposite to the bearing surface; Along the arrangement direction of the bearing surface and the third side surface, the side of the first agitating surface closer to the bearing surface is inclined in a direction closer to the second side surface compared to the side of the first agitating surface farther from the bearing surface, and the side of the second agitating surface closer to the bearing surface is inclined in a direction closer to the first side surface compared to the side of the second agitating surface farther from the bearing surface.

[0014] In this embodiment, along the arrangement direction of the bearing surface and the third side surface, the side of the first agitating surface closer to the bearing surface is inclined towards the second side surface compared to the side of the first agitating surface farther from the bearing surface. Thus, when the first agitating surface agitates the washing water, the impact force exerted by the washing water on the first agitating surface generates two components: one component perpendicular to the first agitating surface, and the other component parallel to the first agitating surface. The component parallel to the first agitating surface will not impact the first agitating surface; only the component perpendicular to the first agitating surface will impact it. Therefore, by using an inclined first agitating surface in this embodiment, the impact force of the washing water on the first agitating surface can be reduced, the stress on the clothes drying garment when agitated, and the risk of damage to the clothes drying garment can be reduced. Similarly, the structure of this embodiment can also reduce the impact force of the washing water on the second agitating surface, reduce the stress on the clothes drying garment when agitated, and reduce the risk of damage to the clothes drying garment.

[0015] In one alternative embodiment, the support member includes: A column extending axially along the inner cylinder; A limiting structure is provided on the outer circumferential surface of the column. When the clothes drying piece is retracted relative to the support member, the limiting structure is used to restrict the clothes drying piece from moving relative to the support member along the circumferential direction of the support member.

[0016] In this embodiment, the support includes a column and a limiting structure. The limiting structure is located on the outer circumferential surface of the column, and the clothes drying rack is located on the periphery of the column. When the clothes drying rack is retracted relative to the support, the clothes drying rack and the limiting structure contact each other along the circumferential direction of the support, so that the limiting structure stops and limits the clothes drying rack along the circumferential direction of the support. In this way, when the clothes drying rack agitates the washing water and the washing water applies an impact force to the clothes drying rack, not only will the hinge between the clothes drying rack and the support share the impact force applied by the washing water, but the limiting structure will also share the impact force applied by the washing water, thereby reducing the stress generated at the hinge and reducing the risk of damage to the hinge due to large stress.

[0017] In one optional embodiment, the limiting structure includes: Limiting ribs are provided on the outer circumferential surface of the column. The clothes drying rack is provided on both sides of the column along the circumferential direction. One end of the clothes drying rack is rotatably connected between two adjacent limiting ribs. When the clothes drying piece is retracted relative to the support member, a portion of the clothes drying piece extends radially beyond the limiting rib and away from the surface of the column along the inner cylinder, and the clothes drying piece is respectively limited and contacted by two adjacent limiting ribs.

[0018] In this embodiment, the limiting structure includes limiting ribs that protrude from the outer circumferential surface of the column. Limiting ribs are provided on both sides of the clothes drying rack along the circumference of the column. When the clothes drying rack is retracted relative to the support member, a part of the clothes drying rack is located between the two limiting ribs and makes limiting contact with the two limiting ribs along the circumferential direction of the column. Thus, whether the impeller rotates in a clockwise or counterclockwise direction, the corresponding limiting ribs can circumferentially limit the clothes drying rack, thereby distributing the impact force applied by the washing water, reducing the stress on the hinge between the clothes drying rack and the support member, and reducing the risk of damage to the hinge when subjected to large stress.

[0019] In addition, setting limit ribs can increase the cross-sectional area of ​​the support, thereby improving the structural strength of the support and reducing the risk of damage to the support when subjected to external forces.

[0020] In one alternative embodiment, the limiting rib has a preset length so that when the clothes drying piece is retracted relative to the support member, the other end of the clothes drying piece makes limiting contact with the limiting rib.

[0021] In this embodiment, the limiting rib has a preset length so that when the clothes drying rack is retracted relative to the support member, the other end of the clothes drying rack makes a limiting contact with the limiting rib. In other words, when the clothes drying rack is retracted relative to the support member, all parts of the clothes drying rack along its own length direction make a limiting contact with the limiting rib in the circumferential direction of the column. This can increase the limiting area of ​​the limiting rib on the clothes drying rack, increase the ability to share the impact force of the washing water, and further reduce the risk of damage to the hinge between the clothes drying rack and the support member.

[0022] In one optional embodiment, the clothes drying component is rotatably connected to the upper end of the limiting rib, and the protrusion height of the limiting rib gradually decreases from top to bottom.

[0023] In this embodiment, the protrusion height of the limiting rib gradually decreases from top to bottom, and the clothes drying piece is rotatably connected to the upper end of the limiting rib. In this way, the limiting rib can provide a larger hinge position for the clothes drying piece, which is conducive to hinged connection between the clothes drying piece and the limiting rib. In addition, the protrusion height of the limiting rib gradually decreases from top to bottom, which allows more of the clothes drying piece to extend beyond the limiting rib, so that more of the clothes drying piece can agitate the washing water or clothes, thereby improving the effect of the clothes drying piece in agitating the washing water or clothes.

[0024] In one optional embodiment, the clothes drying piece has a first side surface distributed in its own width direction, the first side surface including a first limiting plane, which contacts the adjacent limiting rib surface when the clothes drying piece is retracted relative to the support member.

[0025] In this embodiment, the first side surface includes a first limiting plane. When the clothes drying piece is retracted relative to the support, the first limiting plane contacts the adjacent limiting rib surface. This allows the clothes drying piece and the limiting rib to have a larger contact area, thereby increasing the limiting area of ​​the limiting rib on the clothes drying piece, increasing the ability to share the impact force of the washing water, and further reducing the risk of damage to the hinge between the clothes drying piece and the support.

[0026] In one alternative embodiment, the clothes drying rack is strip-shaped and has a bearing surface for hanging clothes when it is unfolded relative to the support member; The line of intersection between the bearing surface and the longitudinal section of the clothes drying piece perpendicular to its own width is a convex arc.

[0027] In this embodiment, the intersection line between the bearing surface and the longitudinal section of the clothes drying piece perpendicular to its own width direction is a convex arc. That is to say, the bearing surface is a convex arc surface distributed along the length direction of the clothes drying piece. The convex arc design makes the middle of the bearing surface the highest and gradually decreases towards both ends. In this way, the moisture on the clothes will not accumulate in the middle, but will be affected by gravity and automatically diverted and dripped to both sides along the bearing surface, thereby improving the drying efficiency of the clothes processing device.

[0028] In an optional embodiment, the pulsator washing machine further includes: A pulsator shaft is disposed on the pulsator and rotatably connected to the inner cylinder; An inner cylinder shaft is disposed in the inner cylinder and rotatably connected to the outer cylinder; the inner cylinder shaft is coaxially arranged with the impeller shaft. The first drive assembly has an output shaft; The clutch has a first state and a second state. When the clutch is in the first state, the output shaft is driven to drive the impeller shaft and the inner cylinder shaft respectively, so as to drive the impeller and the inner cylinder to rotate. When the clutch is in the second state, the output shaft is driven to drive the impeller shaft and disengaged from the inner cylinder shaft, so as to drive the impeller to rotate. The pulsator washing machine has a drying mode. When the pulsator washing machine is in the drying mode, the first drive component drives the pulsator to rotate.

[0029] In this embodiment, when the clothing processing device is in drying mode, the first drive component drives the impeller to rotate, thereby causing the support and the clothes hanging on the support to rotate. During the rotation, the clothes are constantly being tossed up, scattered, and turned over, and their shape is constantly changing. This ensures that all sides of the clothes can be exposed to the high-speed hot air in turn, achieving 360-degree drying without dead angles, ensuring the uniformity and thoroughness of drying, and improving the drying effect.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0038] The current process of drying clothes in top-loading washing machines with drying functions is as follows: hot air is introduced into the inner drum, and the hot air flows through the wet clothes in the inner drum, taking away the moisture from the wet clothes and drying them in the inner drum.

[0039] Because wet clothes are usually stacked inside the drum, hot air can only flow over the surface of the clothes and cannot make sufficient contact with them, resulting in low drying efficiency. Therefore, related technologies incorporate a clothes-drying assembly inside the drum. This assembly hangs the wet clothes up, allowing the hot air to make full contact with them and improving drying efficiency.

[0040] The clothes drying assembly of the related technology includes a support rod and a clothes drying rod. The support rod is fixed to the impeller, and the clothes drying rod is fixed to the outer periphery of the support rod. The clothes drying rod cannot be retracted relative to the support rod. Therefore, the clothes drying assembly occupies a large space in the inner drum, resulting in a decrease in the effective volume of the inner drum and a reduction in the processing capacity of the impeller washing machine.

[0041] This application discloses a pulsator washing machine that can increase the processing capacity of the washing machine. The pulsator washing machine provided in this application will be described in detail below with reference to the accompanying drawings and specific embodiments and application scenarios.

[0042] like Figures 1 to 4 As shown in the figure, this application discloses a pulsator washing machine, including: Housing 100. Housing 100 forms the overall appearance of the garment handling device. Housing 100 is hollow inside to form a receiving cavity. The receiving cavity is configured to accommodate multiple components of the garment handling device, such as circuitry, drive components, and drainage components. Housing 100 may be cuboid in shape for placement against a wall.

[0043] The outer tub 210 is located inside the housing 100. Specifically, the outer tub 210 can be suspended inside the housing 100 by a suspension spring, and the outer tub 210 is used to hold washing water.

[0044] The inner tube 220 is rotatably disposed inside the outer tube 210, and the inner tube 220 is used to hold clothing.

[0045] The impeller 230 is rotatably located at the bottom of the inner drum 220. During rotation, the impeller 230 can agitate the washing water in the inner drum 220, causing the clothes to move and rub within the inner drum 220, thereby achieving the purpose of cleaning the clothes.

[0046] The drying component 300 is located inside the housing 100. The air outlet of the drying component 300 is connected to the space inside the inner cylinder 220 to deliver hot air to the inner cylinder 220.

[0047] In some embodiments, the housing 100 is further provided with a circulation pipe (not shown in the figure), and the outer cylinder 210 is provided with an exhaust port. One end of the circulation pipe is connected to the exhaust port, and the other end is connected to the air inlet of the drying assembly 300. A condenser is provided in the circulation pipe to condense the hot and humid air discharged from the exhaust port. Of course, the clothing processing device may also not include the circulation pipe and the condenser, in which case the hot and humid air can be discharged from the housing 100 by direct exhaust.

[0048] For example, the drying assembly 300 may include a fan, a heater, and a drying tube. The air outlet of the fan is connected to the air inlet of the drying tube, and the air outlet of the drying tube is connected to the space inside the outer cylinder 210. The heater is used to heat the air delivered by the fan. The heater may be located at the air inlet of the fan or inside the drying tube.

[0049] Clothes drying assembly 400, including: The support member 410 is located on the impeller 230 and can rotate with the impeller 230 to provide an installation base for the clothes drying unit 420.

[0050] The clothes drying component 420 is located around the support component 410. One end of the clothes drying component 420 is rotatably connected to the support component 410 so that the clothes drying component 420 can be unfolded or retracted relative to the support component 410.

[0051] It should be noted that, compared to when the clothes drying component 420 is unfolded relative to the support component 410, when the clothes drying component 420 is folded relative to the support component 410, the other end of the clothes drying component 420 is closer to the outer peripheral surface of the support component 410. That is, when the clothes drying component 420 is unfolded relative to the support component 410, the other end of the clothes drying component 420 is farther away from the outer peripheral surface of the support component 410; when the clothes drying component 420 is folded relative to the support component 410, the other end of the clothes drying component 420 is closer to the outer peripheral surface of the support component 410. For example, when the clothes drying component 420 is folded relative to the support component 410, the clothes drying component 420 can be in contact with the outer peripheral surface of the support component 410; or there can be a gap between the clothes drying component 420 and the outer peripheral surface of the support component 410, and this application does not limit this.

[0052] When the clothes drying rack 420 is unfolded relative to the support member 410, the clothes drying rack 420 is used to hang clothes; when the clothes drying rack 420 is retracted relative to the support member 410, at least a portion of the clothes drying rack 420 extends beyond the outer circumferential surface of the support member 410 along the radial direction of the inner drum 220, so that the clothes drying rack 420 agitates the washing water or clothes as it rotates with the impeller 230.

[0053] In this application, the clothes drying assembly 400 includes a support member 410 and a clothes drying component 420. The clothes drying component 420 is located around the support member 410, and one end of the clothes drying component 420 is rotatably connected to the support member 410 so that the clothes drying component 420 can be unfolded or retracted relative to the support member 410.

[0054] When clothes need to be dried, the clothes drying rack 420 can be unfolded relative to the support 410. At this time, the clothes drying rack 420 can be used to hang clothes. Compared with the clothes being stacked inside the inner drum 220, hanging the clothes on the clothes drying rack 420 can increase the contact area between the clothes and the hot air inside the inner drum 220, thereby allowing the hot air to fully contact the clothes and improving the drying efficiency.

[0055] When washing clothes, the clothes drying rack 420 can be folded up relative to the support 410. At this time, the end of the clothes drying rack 420 away from the support 410 is closer to the support 410, thereby reducing the overall size of the clothes drying assembly 400 and reducing the space occupied by the clothes drying assembly 400 in the inner drum 220, thus increasing the effective volume of the inner drum 220 and increasing the processing capacity of the pulsator washing machine. Furthermore, when the clothes drying rack 420 is folded up relative to the support 410, at least a portion of the clothes drying rack 420 extends beyond the outer circumference of the support 410 along the radial direction of the inner drum 220. In this way, the clothes drying rack 420 can directly agitate the washing water or clothes in the inner drum 220 as it rotates with the pulsator 230. That is, the clothes drying rack 420 can be used as an agitator, thereby improving the cleaning effect on clothes. As can be seen, the clothes drying component 420 of this application can be used to hang clothes when unfolded, and can be used as an agitator when folded to agitate the washing water or clothes in the inner drum 220, thus achieving the effect of two uses in one.

[0056] Please see Figure 3 In one optional embodiment, the clothes drying unit 420 has a first side surface 421 distributed circumferentially along the inner drum 220. The first side surface 421 includes a first agitation surface 4211. When the clothes drying unit 420 is retracted relative to the support member 410, the first agitation surface 4211 extends radially beyond the outer peripheral surface of the support member 410 along the inner drum 220. The first agitation surface 4211 is used to agitate the washing water or clothes in the inner drum 220.

[0057] The ratio of the area of ​​the first stirring surface 4211 to the total area of ​​the first side surface 421 is greater than or equal to 0.5. For example, the ratio of the area of ​​the first stirring surface 4211 to the total area of ​​the first side surface 421 can be 0.53, 0.6, 0.7, 0.8, 0.9, 0.95, 1.0, etc., and this application does not limit it.

[0058] If the ratio of the area of ​​the first agitation surface 4211 to the total area of ​​the first side surface 421 is less than 0.5, then the portion of the clothes drying piece 420 that extends beyond the outer periphery of the support member 410 when it is folded up will be smaller. The area of ​​the first agitation surface 4211 that extends beyond the outer periphery of the support member 410 on the first side surface 421 will be smaller. Obviously, this will weaken the agitation effect of the clothes drying piece 420 on the washing water or clothes when it is folded up relative to the support member 410, thereby weakening the cleaning effect of the clothes drying piece 420 on the clothes when it is folded up.

[0059] Therefore, in this embodiment, the ratio of the area of ​​the first agitation surface 4211 to the total area of ​​the first side surface 421 is set to be greater than or equal to 0.5, so that when the clothes drying piece 420 is folded up, the portion extending beyond the outer periphery of the support member 410 is larger, thereby ensuring the agitation effect of the clothes drying piece 420 on the washing water or clothes when folded up relative to the support member 410, and thus ensuring the cleaning effect of the clothes drying piece 420 on the clothes when folded up.

[0060] In some embodiments, the clothes drying rack 420 can be manually rotated to unfold or retract relative to the support member 410. In this case, a damping structure can be provided between the clothes drying rack 420 and the support member 410 to allow the clothes drying rack 420 to hover at any position during rotation. In other embodiments, please refer to... Figure 5 The clothing handling device also includes a second drive component 600, which is connected to the clothes drying component 420 to drive the clothes drying component 420 to rotate, so that the clothes drying component 420 unfolds or retracts relative to the support component 410. This eliminates the need for manual switching of the state of the clothes drying component 420, thus improving the user experience.

[0061] In some embodiments, please refer to Figures 6 to 9 The second drive assembly 600 includes a drive member 610 and a traction rope 630. The drive member 610 is located outside the outer cylinder 210 to improve the environment of the drive member 610 and prevent damage to the drive member 610. One end of the traction rope 630 is connected to the drive member 610, and the other end is connected to the end of the clothes drying unit 420 that is hinged to the support member 410. The drive member 610 can pull the traction rope 630 to switch the clothes drying unit 420 from a state of being retracted relative to the support member 410 to a state of being extended relative to the support member 410.

[0062] Furthermore, the second drive assembly 600 also includes an elastic reset member 640, which is disposed between the clothes drying member 420 and the support member 410, so that the clothes drying member 420 resets from an unfolded state relative to the support member 410 to a retracted state relative to the support member 410. It should be noted that the second drive assembly 600 may also not include the elastic reset member 640, in which case the clothes drying member 420 can be reset by its own weight.

[0063] Furthermore, the second drive assembly 600 also includes a transmission rod 620 that slides through the bottom of the outer cylinder 210 and the bottom of the inner cylinder 220. One end of the transmission rod 620 is connected to the drive member 610, and the other end of the transmission rod 620 and the traction rope 630 are both located inside the support member 410. The end of the traction rope 630 away from the clothes drying member 420 is connected to the other end of the transmission rod 620. The drive member 610 is used to drive the transmission rod 620 to slide downward to pull the traction rope 630.

[0064] It should be noted that the inner cylinder 220 is rotatably disposed inside the outer cylinder 210 via the inner cylinder shaft 520. The inner cylinder shaft 520 passes through the cylinder body of the outer cylinder 210 and extends out of the outer cylinder 210. The impeller shaft 510 is coaxially disposed inside the inner cylinder shaft 520. The transmission rod 620 mentioned above is coaxially disposed inside the impeller shaft 510.

[0065] For example, one end of the transmission rod 620 is provided with a disc-shaped portion, and the driving member 610 includes a traction device 611 and a connecting rod 612. The middle part of the connecting rod 612 is hinged to the housing 100. The traction device 611 is connected to one end of the connecting rod 612, and the other end of the traction device 611 overlaps above the disc-shaped portion of the transmission rod 620. The traction device 611 pulls one end of the connecting rod 612, which can drive the other end of the connecting rod 612 to swing downward to press the disc-shaped portion, thereby causing the transmission rod 620 to slide downward, and then pull the traction rope 630 to unfold the clothes drying device 420.

[0066] Of course, the second drive assembly 600 may not include the aforementioned drive component 610, traction rope 630, elastic reset component 640, etc. In this case, the second drive assembly 600 can be a motor, which is directly connected to the clothes drying component 420 to drive the clothes drying component 420 to rotate. To prevent water from entering the motor, a waterproof motor can be used, or a sealed box can be installed outside the motor.

[0067] Please see Figure 3 In one optional embodiment, the clothes drying component 420 has a first side surface 421 and a second side surface 422 distributed circumferentially along the inner cylinder 220. The first side surface 421 includes a first agitation surface 4211 extending radially beyond the outer peripheral surface of the support member 410 along the inner cylinder 220. The second side surface 422 includes a second agitation surface 4221 extending radially beyond the outer peripheral surface of the support member 410 along the inner cylinder 220. The clothes drying component 420 has a bearing surface 423 for hanging clothes when it is unfolded relative to the support member 410, and a third side surface 424 disposed opposite to the bearing surface 423.

[0068] Specifically, when the pulsator washing machine is in the washing state, the pulsator 230 will rotate back and forth in the clockwise and counterclockwise directions. When the clothes drying rack 420 is closed relative to the support 410 and the pulsator 230 rotates in the clockwise direction, the second agitation surface 4221 will agitate the washing water or clothes in the inner drum 220. When the clothes drying rack 420 is closed relative to the support 410 and the pulsator 230 rotates in the counterclockwise direction, the first agitation surface 4211 will agitate the washing water or clothes in the inner drum 220.

[0069] Along the arrangement direction of the bearing surface 423 and the third side surface 424 ( Figure 3(As indicated by the arrow in the middle), the side of the first agitation surface 4211 closest to the bearing surface 423 is inclined in a direction closer to the second side surface 422 compared to the side of the first agitation surface 4211 furthest from the bearing surface 423, and the side of the second agitation surface 4221 closest to the bearing surface 423 is inclined in a direction closer to the first side surface 421 compared to the side of the second agitation surface 4221 furthest from the bearing surface 423.

[0070] Specifically, when the clothes drying component 420 is retracted relative to the support component 410, the side of the first stirring surface 4211 that is closer to the bearing surface 423 is the side of the first stirring surface 4211 that is away from the support component 410, and the side of the second stirring surface 4221 that is closer to the bearing surface 423 is the side of the second stirring surface 4221 that is away from the support component 410.

[0071] In this embodiment, along the arrangement direction of the bearing surface 423 and the third side surface 424, the side of the first agitating surface 4211 closest to the bearing surface 423 is inclined towards the second side surface 422 compared to the side of the first agitating surface 4211 furthest from the bearing surface 423. Thus, when the first agitating surface 4211 agitates the washing water, the impact force exerted by the washing water on the first agitating surface 4211 generates two components: one component perpendicular to the first agitating surface 4211, and the other component parallel to the first agitating surface 4211. The component parallel to the first agitating surface 4211 will not impact the first agitating surface 4211; only the component perpendicular to the first agitating surface 4211 will impact it. Therefore, by using an inclined first agitating surface 4211 in this embodiment, the impact force of the washing water on the first agitating surface 4211 can be reduced, the stress on the clothes drying rack 420 when agitating the washing water can be reduced, and the risk of damage to the clothes drying rack 420 can be reduced.

[0072] Similarly, along the arrangement direction of the bearing surface 423 and the third side surface 424, the side of the second agitation surface 4221 closest to the bearing surface 423 is inclined towards the first side surface 421 compared to the side of the second agitation surface 4221 furthest from the bearing surface 423. Thus, when the second agitation surface 4221 agitates the washing water, the impact force exerted by the washing water on the second agitation surface 4221 will also generate two components: one component is perpendicular to the second agitation surface 4221, and the other component is parallel to the second agitation surface 4221. This reduces the impact force of the washing water on the second agitation surface 4221, reduces the stress on the clothes drying piece 420 when agitating the washing water, and reduces the risk of damage to the clothes drying piece 420.

[0073] Please see Figure 3 In one alternative embodiment, the support 410 includes: The column 411 extends along the axial direction of the inner cylinder 220 and is mounted on the impeller 230. The clothes drying unit 420 is located around the column 411.

[0074] The limiting structure 412 is provided on the outer peripheral surface of the column 411. When the clothes drying part 420 is retracted relative to the support member 410, the limiting structure 412 is used to restrict the clothes drying part 420 from moving relative to the support member 410 along the circumferential direction of the support member 410.

[0075] In this embodiment, the support member 410 includes a column 411 and a limiting structure 412. The limiting structure 412 is disposed on the outer peripheral surface of the column 411. The clothes drying piece 420 is located on the periphery of the column 411. When the clothes drying piece 420 is retracted relative to the support member 410, the clothes drying piece 420 and the limiting structure 412 contact each other along the circumference of the support member 410, so that the limiting structure 412 stops and limits the clothes drying piece 420 along the circumference of the support member 410. In this way, when the clothes drying piece 420 agitates the washing water and the washing water applies an impact force to the clothes drying piece 420, not only will the hinge between the clothes drying piece 420 and the support member 410 share the impact force applied by the washing water, but the limiting structure 412 will also share the impact force applied by the washing water, thereby reducing the stress generated at the hinge and reducing the risk of damage to the hinge due to large stress. Of course, the support member 410 may not include the aforementioned limiting structure 412. In this case, the impact force exerted by the washing water can be shared through the hinge between the clothes drying part 420 and the support member 410. This application does not limit this.

[0076] In some embodiments, the limiting structure 412 may be a limiting groove provided on the outer peripheral surface of the column 411. See also... Figure 3 In one optional embodiment, the limiting structure 412 includes: Limiting ribs are provided on the outer circumferential surface of the column 411. Limiting ribs are provided on both sides of the clothes drying component 420 along the circumference of the column 411. One end of the clothes drying component 420 is rotatably connected between two adjacent limiting ribs. That is to say, one end of the clothes drying component 420 is hinged to the two limiting ribs, so that it can be unfolded or retracted relative to the support component 410.

[0077] When the clothes drying component 420 is retracted relative to the support component 410, a portion of the clothes drying component 420 extends radially beyond the limiting ribs and away from the surface of the column 411 along the inner cylinder 220, and the clothes drying component 420 makes limiting contact with two adjacent limiting ribs respectively.

[0078] In this embodiment, the limiting structure 412 includes limiting ribs that protrude from the outer circumferential surface of the column 411. The clothes drying piece 420 is provided with limiting ribs on both sides of the column 411 in the circumferential direction. When the clothes drying piece 420 is retracted relative to the support member 410, a part of the clothes drying piece 420 is located between the two limiting ribs and is respectively limited and contacted with the two limiting ribs in the circumferential direction of the column 411. Thus, whether the impeller 230 rotates in the clockwise direction or the counterclockwise direction, the corresponding limiting ribs can circumferentially limit the clothes drying piece 420, thereby distributing the impact force applied by the washing water, reducing the stress on the hinge between the clothes drying piece 420 and the support member 410, and reducing the risk of damage to the hinge when subjected to large stress.

[0079] In addition, the cross-sectional area of ​​the support member 410 can be increased by setting the limiting ribs, thereby improving the structural strength of the support member 410 and reducing the risk of damage to the support member 410 when subjected to external forces.

[0080] Please see Figure 4 In one alternative embodiment, the limiting rib has a preset length so that when the clothes drying piece 420 is retracted relative to the support member 410, the other end of the clothes drying piece 420 is in limiting contact with the limiting rib.

[0081] In this embodiment, the limiting rib has a preset length so that when the clothes drying piece 420 is retracted relative to the support member 410, the other end of the clothes drying piece 420 makes limiting contact with the limiting rib. That is, when the clothes drying piece 420 is retracted relative to the support member 410, all parts of the clothes drying piece 420 along its own length direction make limiting contact with the limiting rib in the circumferential direction of the column 411. This increases the limiting area of ​​the limiting rib on the clothes drying piece 420, increases the ability to distribute the impact force of washing water, and further reduces the risk of damage to the hinge between the clothes drying piece 420 and the support member 410. Of course, when the clothes drying piece 420 is retracted relative to the support member 410, the other end of the clothes drying piece 420 may not make limiting contact with the limiting rib, and this application does not limit this.

[0082] Please see Figure 3 In one optional embodiment, the clothes drying piece 420 is rotatably connected to the upper end of the limiting rib, and the protrusion height of the limiting rib gradually decreases from top to bottom.

[0083] In this embodiment, the protrusion height of the limiting rib gradually decreases from top to bottom. The clothes drying piece 420 is rotatably connected to the upper end of the limiting rib. This allows the limiting rib to provide a larger hinge position for the clothes drying piece 420, facilitating hinge connection between the clothes drying piece 420 and the limiting rib. Furthermore, the gradual decrease in the protrusion height of the limiting rib from top to bottom allows more of the clothes drying piece 420 to extend beyond the limiting rib, enabling more of the clothes drying piece 420 to agitate the washing water or clothes, thereby improving the agitation effect of the clothes drying piece 420. Of course, the protrusion height of the limiting rib can also remain constant from top to bottom or gradually increase from top to bottom; this application does not impose any limitations on this.

[0084] Please see Figure 3 In one optional embodiment, the clothes drying component 420 has a first side surface 421 distributed along its width direction. The first side surface 421 includes a first limiting plane 4212. When the clothes drying component 420 is retracted relative to the support member 410, the first limiting plane 4212 contacts the adjacent limiting rib surface. It should be noted that when this embodiment is combined with an embodiment in which the first side surface 421 includes a first agitation surface 4211, the first limiting plane 4212 is in contact with the first agitation surface 4211.

[0085] In this embodiment, the first side surface 421 includes a first limiting plane 4212. When the clothes drying piece 420 is retracted relative to the support member 410, the first limiting plane 4212 contacts the adjacent limiting rib surface. This allows for a larger contact area between the clothes drying piece 420 and the limiting rib, thereby increasing the limiting area of ​​the limiting rib on the clothes drying piece 420, increasing the ability to distribute the impact force of the washing water, and further reducing the risk of damage to the hinge between the clothes drying piece 420 and the support member 410. Of course, the clothes drying piece 420 may also contact the limiting rib line; this application does not limit this.

[0086] Please see Figure 3 In one optional embodiment, the clothes drying component 420 has a second side surface 422 distributed in its own width direction. The second side surface 422 includes a second limiting plane 4222. When the clothes drying component 420 is retracted relative to the support member 410, the second limiting plane 4222 contacts the adjacent limiting rib surface.

[0087] In this embodiment, the second side surface 422 includes a second limiting plane 4222. When the clothes drying piece 420 is retracted relative to the support member 410, the second limiting plane 4222 contacts the adjacent limiting rib surface. This allows for a larger contact area between the clothes drying piece 420 and the limiting rib, thereby increasing the limiting area of ​​the limiting rib on the clothes drying piece 420, increasing the ability to distribute the impact force of the washing water, and further reducing the risk of damage to the hinge between the clothes drying piece 420 and the support member 410. Of course, the clothes drying piece 420 may also contact the limiting rib line; this application does not limit this.

[0088] Please see Figure 3 In one optional embodiment, the clothes drying component 420 is strip-shaped and has a bearing surface 423 for hanging clothes when it is unfolded relative to the support 410. The intersection line of the bearing surface 423 and the longitudinal section of the clothes drying component 420 perpendicular to its own width direction is a convex arc.

[0089] In this embodiment, the intersection line of the bearing surface 423 and the longitudinal section of the clothes drying piece 420 perpendicular to its own width direction is a convex arc. That is to say, the bearing surface 423 is a convex arc surface distributed along the length direction of the clothes drying piece 420. The convex arc design makes the middle of the bearing surface 423 the highest and gradually decreases towards both ends. In this way, the moisture on the clothes will not accumulate in the middle, but will be affected by gravity and automatically diverted and dripped to both sides along the bearing surface 423 to improve the drying efficiency of the clothes processing device.

[0090] In one optional embodiment, the pulsator washing machine further includes: The impeller shaft 510 is located on the impeller 230 and is rotatably connected to the inner cylinder 220.

[0091] The inner cylinder shaft 520 is located in the inner cylinder 220 and is rotatably connected to the outer cylinder 210. The inner cylinder shaft 520 is coaxially arranged with the impeller shaft 510.

[0092] The first drive assembly 540 has an output shaft. For example, the first drive assembly 540 may be a direct-drive motor.

[0093] The clutch 530 has a first state and a second state. When the clutch 530 is in the first state, the output shaft is connected to the impeller shaft 510 and the inner cylinder shaft 520 respectively to drive the impeller 230 and the inner cylinder 220 to rotate. When the clutch 530 is in the second state, the output shaft is connected to the impeller shaft 510 and disconnected from the inner cylinder shaft 520 to drive the impeller 230 to rotate.

[0094] Specifically, when the garment handling device is washing clothes, the drying component 300 can be turned off and the clutch 530 can be switched to the second state. At this time, the first drive component 540 only drives the impeller 230 to rotate without driving the inner drum 220 to rotate, so that the garment handling device is in the washing state. When the garment handling device is dehydrating the clothes, the drying component 300 can be turned off and the clutch 530 can be switched to the first state. At this time, the first drive component 540 drives both the impeller 230 and the inner drum 220 to rotate, so that the garment handling device is in the dehydration state.

[0095] The pulsator washing machine has a drying mode. When the pulsator washing machine is in the drying mode, the first drive assembly 540 drives the pulsator 230 to rotate.

[0096] In this embodiment, when the clothing processing device is in drying mode, the first drive component 540 drives the impeller 230 to rotate, thereby causing the support member 410 and the clothes hanging on the support member 410 to rotate. During the rotation, the clothes are constantly tossed up, scattered, and turned over, and their shape is constantly changing. This ensures that all sides of the clothes can be exposed to the high-speed hot air in turn, achieving 360-degree drying without dead angles, ensuring the uniformity and thoroughness of drying, and improving the drying effect.

[0097] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
