Description

Technical Field

[0001] This invention relates to the field of fabric processing equipment technology, and in particular to a balance ring, an inner drum assembly, fabric processing equipment, and a control method. Background Technology

[0002] In the field of fabric processing equipment technology, the inner tub assembly is one of the core components of a pulsator washing machine. For example, a perforated inner tub usually relies on the drainage groove on the balance ring for drainage, which has low drainage efficiency. The water flow is slow when it is dehydrated from the balance ring, which affects the dehydration efficiency of the washing machine. Poor drainage performance of the inner tub assembly can lead to problems such as sewage residue, increased load, and component corrosion, which in turn reduces washing cleanliness, causes odors and mold, and increases the load on key components such as motors and bearings, thus shortening the overall service life of the washing machine. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that in the prior art, the inner tub assembly relies on a conventional drainage channel for drainage, which has low drainage efficiency. The water flow is slow when it is dehydrated from the balance ring, which affects the dehydration efficiency of the washing machine. The drainage performance of the inner tub assembly directly affects the washing effect and service life of the washing machine. Therefore, the present invention provides a balance ring, an inner tub assembly, a fabric treatment device and a control method.

[0004] This invention aims to provide a balancing ring for a fabric treatment device, comprising:

[0005] A ring body, wherein multiple drainage grooves are spaced apart along the circumference of the ring body;

[0006] Each of the drainage channels extends through the wall thickness of the ring body, and the ring body has a water guide section on its outer peripheral wall at the outlet of the drainage channel for guiding water flow out.

[0007] The outer peripheral wall of the ring has a ring positioning edge, the outlet of the drainage channel is higher than the ring positioning edge, the outlet sidewall of the drainage channel extends toward the ring positioning edge, and the water guiding part is an inclined wall that transitionally connects the outlet sidewall of the drainage channel and the ring positioning edge.

[0008] In some embodiments, the inclined wall has an angle θ with respect to the horizontal plane, where 10°≤θ≤60°.

[0009] In some embodiments, the drainage channel includes a horizontal channel section and a vertical channel section. The horizontal channel section is formed radially on the wall of the ring body along the positioning edge of the ring body, and the vertical channel section is formed axially on the outer peripheral wall of the ring body between the lower edge of the ring body and the positioning edge of the ring body.

[0010] In some embodiments, the balancing ring includes:

[0011] At least one positioning part protrudes from the positioning edge of the ring body, the positioning part being used to insert into a positioning groove on the barrel of the fabric processing equipment to position the ring body on the barrel body.

[0012] In some embodiments, an inner barrel assembly is provided, comprising:

[0013] The aforementioned balance ring;

[0014] The barrel body has a balance ring mounted on its top. The horizontal groove of the drainage trough forms a first drainage channel with the top of the barrel body, and the vertical groove of the drainage trough forms a second drainage channel with the inner wall of the barrel body. The first drainage channel and the second drainage channel together form a drainage channel connecting the inside and outside of the inner barrel.

[0015] The water guide section and the top of the barrel form a through groove with an sloping top, and the through groove is connected to the horizontal groove section.

[0016] In some embodiments, a positioning groove is provided at the top of the barrel body, and the positioning groove is used to engage with the positioning part on the balance ring.

[0017] In some embodiments, the inner tub assembly includes an inner tub bottom fitted to the bottom end of the tub body;

[0018] A first protrusion protruding into the interior of the barrel is formed on the bottom of the inner barrel. The first protrusion is constructed as a ring, and the central axis of the first protrusion is collinear with the central axis of the barrel. The first protrusion is also in clearance fit with the outer peripheral side of the impeller located on the barrel.

[0019] In some embodiments, a second protrusion protruding into the barrel is formed on the bottom of the inner barrel and inside the first protrusion. The second protrusion is constructed as a multi-segmented arc-shaped protrusion. A third protrusion protruding into the barrel is formed on the bottom of the inner barrel and inside the second protrusion. The third protrusion is constructed as a frustum. Water collection areas are formed between the second protrusion and the third protrusion, and at the intervals of the second protrusion. First drain holes are provided on the bottom wall of the barrel at intervals corresponding to the water collection areas.

[0020] In some embodiments, a second drain hole is provided at a distance on the side wall of the first protrusion facing the central axis of the barrel.

[0021] In some embodiments, a fabric treatment apparatus is provided, comprising:

[0022] The aforementioned inner barrel assembly.

[0023] In some embodiments, a control method for the above-described fabric processing equipment is provided, comprising:

[0024] When the fabric processing equipment is in the dehydration stage, the motor of the fabric processing equipment is controlled to run for a first preset time and then paused for a second preset time, wherein the second preset time is less than the first preset time.

[0025] The solution provided by this invention has the following advantages compared with the prior art:

[0026] By setting a water guide at the outlet of the drain tank to guide the water flow, the washing water that remains on the balance ring can quickly pass through the drain tank through this water guide, thereby accelerating its exit from the balance ring and out of the inner tub. This improves the drainage efficiency of the non-perforated inner tub, thereby enhancing the drainage performance of the inner tub and reducing the probability of sewage residue, increased load, and component corrosion. This, in turn, improves washing cleanliness, prevents odors and mold, and avoids increasing the load on key components such as the motor and bearings, thus extending the overall service life of the pulsator washing machine.

Therefore, they should not be construed as limiting this invention.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "contact," and "communication" should be interpreted broadly. 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.

[0041] The inner tub usually relies on the drain groove on the balance ring for drainage, which has low drainage efficiency. The water flow is slow when it is dehydrated from the balance ring, which affects the dehydration efficiency of the washing machine. Poor drainage performance of the inner tub components can lead to problems such as sewage residue, increased load, and component corrosion, which in turn reduces the washing cleanliness, causes odors and mold, and increases the load on key components such as motors and bearings, thus shortening the overall lifespan of the washing machine.

[0042] 1. Slow drainage speed of the balance ring: The water flows slowly when it is dehydrated from the balance ring, which affects the dehydration efficiency of the washing machine.

[0043] 2. Slow drainage from the tub base: The tub base drains water slowly, resulting in more residual water after washing, which affects the user experience.

[0044] Based on this, the following embodiments are proposed.

[0045] Example 1:

[0046] like Figures 1 to 6 As shown, this embodiment provides a balance ring for a fabric processing device, including: a ring body 1, on which a plurality of drainage grooves 101 are arranged at intervals along the circumference, each of the drainage grooves 101 penetrating in the wall thickness direction of the ring body 1, and the ring body 1 has a water guiding part 102 for guiding water flow out at the outlet position of the drainage groove 101 on its outer peripheral wall.

[0047] In this embodiment, the balance ring can be applied to a pulsator washing machine. During the spin-drying process of the pulsator washing machine, the high-speed rotation of the inner tub generates a large centrifugal force. Under the action of centrifugal force, the water flow and a large amount of foam in the inner tub move towards the tub wall and eventually surge upward to the balance ring. The water flow and foam in the inner tub together form the washing water. By providing a water guide 102 at the outlet of the drain trough 101 to guide the water flow out, the washing water retained on the balance ring can quickly pass through the drain trough 101 through this water guide 102, thereby accelerating its exit from the balance ring and discharge from the inner tub.

[0048] It should be noted that both non-perforated inner tubs and ordinary inner tubs rely on drainage channels on the balance ring for drainage. The balance ring proposed in this embodiment is applicable to both non-perforated inner tubs and ordinary perforated inner tubs. Due to centrifugal force, water tends to rise and accumulate below the balance ring. In ordinary perforated inner tubs, most of the water can be drained through the dewatering holes in the tub wall, but the water at the very top still needs to be drained through the drainage channels on the balance ring.

[0049] Especially when the inner tub is a non-perforated inner tub, drainage usually relies on the drain groove on the balance ring, which has low drainage efficiency. The water flow is slow when it is dehydrated from the balance ring, affecting the dehydration efficiency of the washing machine. In this embodiment, by setting a water guide part 102 at the outlet of the drain groove 101 to guide the water flow out, the drainage efficiency of the non-perforated inner tub is improved, thereby improving the drainage performance of the inner tub, reducing the probability of sewage residue, increased load, and component corrosion, thereby improving washing cleanliness, avoiding odor and mold, and avoiding increasing the load on key components such as motors and bearings, thus extending the overall service life of the pulsator washing machine.

[0050] like Figure 2 , 4As shown in Figure 6, in one implementation of this embodiment, the outer peripheral wall of the ring body 1 has a ring positioning edge 104, the outlet of the drainage groove 101 is higher than the ring positioning edge 104, the outlet sidewall of the drainage groove 101 extends toward the ring positioning edge 104, and the water guiding part 102 is an inclined wall that transitionally connects the outlet sidewall of the drainage groove 101 and the ring positioning edge 104.

[0051] In this embodiment, by setting an inclined wall on the side of the drain trough 101 and gradually decreasing the height of the inclined wall from near the drain trough 101 to away from the drain trough 101, a flow guiding structure is formed on both sides of the drain trough 101. The washing water that is stuck in the balance ring can quickly pass through the drain trough 101 through this flow guiding structure, thereby accelerating its exit from the balance ring and discharge outside the inner tub.

[0052] The effect of the inclined wall on the discharge of water is as follows:

[0053] ① When the inner tub drives the balance ring to rotate, the water flow is thrown by centrifugal force onto the inclined wall and the wall of the drainage trough 101. The inclined wall has a slope that gradually decreases from near the drainage trough 101 to away from the drainage trough 101. This causes the water flow to be subjected to both the gravitational force along the inclined wall towards the drainage trough 101 and the centrifugal force along the radial direction of the balance ring away from its center. Both of these forces can push the water flow to concentrate rapidly towards the center of the drainage trough 101, realizing the directional convergence of the water flow driven by the combined force. This makes the discharge power of the water flow stronger and the flow direction of the water flow more precise.

[0054] ② The inclined wall is a continuous, smooth slope without sharp edges, which can reduce the flow resistance of water. When the water flows along the slope of the inclined wall, the frictional resistance of the water flowing from the inclined wall of the balance ring to the drainage channel 101 is greatly reduced. There will be no collision between multiple water streams or turbulent eddies at the drainage channel 101, which allows the water to converge more smoothly at the drainage channel 101 and avoids the water from stagnating near the balance ring.

[0055] ③ Enhancing drainage impact force through flow collection

[0056] The inclined wall can guide the dispersed water flow towards the drain trough 101, causing the water flow to gather at the inlet of the drain trough 101 and reducing the cross-sectional area of ​​the water flow. According to the principle of fluid continuity, the flow velocity of the water flow will increase accordingly, and a high-speed jet will be formed to penetrate the drain trough 101 with a stronger impact force and be discharged outside the inner barrel, thereby improving the efficiency of water discharge during the dehydration stage.

[0057] The effect of the inclined wall on foam discharge is as follows:

[0058] ① The density of foam in the water flow is much less than that of water, so the foam will continue to rise. The inclination angle of the inclined wall will make the foam always adhere to the inclined wall and float and move towards the drainage channel 101. Therefore, the foam does not need to break through the turbulent water flow to quickly float to the water surface in the drainage channel 101 along the inclined wall, which greatly shortens the residence time of the foam in the water flow.

[0059] ② When the water flows rapidly along the inclined wall toward the drainage trough 101, under the action of Bernoulli's principle, the water pressure at the inlet of the drainage trough 101 is low, and it passes through the drainage trough 101 in the form of a high-speed jet. Therefore, a negative pressure is formed in the drainage trough 101. This negative pressure can adsorb the tiny bubbles in the water that have not yet floated to the surface into the drainage trough 101, so that the bubbles are discharged into the drainage trough 101 along with the water flow, and prevent the bubbles from lingering near the drainage trough 101.

[0060] ③ As a smooth slope, the inclined wall does not have the sharp edges and depressions of a straight trough wall, which are easy to trap foam. Therefore, the foam is difficult to adhere to the inclined wall and can only enter the drainage trough 101 along the inclined wall and be discharged out of the balance ring with the water, thus avoiding the formation of air blockage at the drainage trough 101 that hinders the drainage efficiency of the drainage balance ring.

[0061] By incorporating an inclined wall on the side of the drain trough 101, both water flow and foam are guided, allowing the washing water to flow quickly along the slope of the wall and exit outside the balance ring. The gradually changing height of the inclined wall makes the water flow path smoother, reducing resistance during drainage and lowering the risk of water accumulating and remaining at the balance ring. This accelerates the dehydration and discharge of water and foam from the balance ring, improving the dehydration efficiency of the pulsator washing machine. Simultaneously, the inclined wall of the drain trough 101 helps maintain the operational balance of the pulsator washing machine during the dehydration process, thereby enhancing the overall operational stability and reliability of the machine.

[0062] Optionally, such as Figure 4 As shown, in one implementation of this embodiment, the inclined wall has an inclined angle θ with the horizontal plane, where 10°≤θ≤60°.

[0063] In this embodiment, the angle θ determines the efficiency of the inclined wall's guiding effect on the washing water. When θ equals 60°, the inclined wall is almost parallel to the horizontal plane. At this time, the guiding slope of the inclined wall is very gentle, and the guiding effect on the washing water flowing along the inclined wall is weak. The effect of the inclined wall on improving the drainage speed is poor. When θ equals 60°, the inclination of the inclined wall is large, and the obstruction effect of the inclined wall on the washing water is enhanced, which also fails to achieve the ideal effect of accelerating drainage. Only when the angle θ is within the reasonable range of 10°≤θ≤60° can the inclined wall form an effective guiding slope.

[0064] Within this angle range, the inclined wall can fully exert its guiding function, directing the washing water to drain quickly and smoothly, further improving drainage efficiency and preventing the accumulation of washing water near the balance ring. Moreover, the appropriate angle setting can reduce noise generated during washing water drainage, enhancing the user experience. At the same time, this angle design also facilitates the manufacturing of the balance ring, reducing production difficulty and costs while ensuring the guiding effect.

[0065] In one embodiment, when θ is set to 30°, the washing water reaches the inclined wall under the action of centrifugal force and then slides down the 30° slope and is discharged quickly under the combined action of gravity and centrifugal force. This angle will not cause the washing water to flow slowly due to the slope being too gentle, nor will it cause excessive obstruction to the water flow due to the slope being too steep.

[0066] In another embodiment, θ is set to 60°. Although the slope is relatively steep, it is still within a reasonable range. The washing water can be quickly discharged along the slope under the action of centrifugal force, and at the same time, the impact of the washing water on the inclined wall can be reduced to a certain extent, thus extending the service life of the balance ring.

[0067] By limiting the angle θ between the inclined wall and the horizontal plane to within the range of 10°≤θ≤60°, the guiding slope of the inclined wall is made more reasonable, further optimizing the discharge path of the washing water, enhancing the guiding effect of the balance ring, and effectively improving the drainage speed of the inner tub.

[0068] Optionally, such as Figure 6 As shown, in one implementation of this embodiment, the drainage trough 101 includes a horizontal trough section 1013 and a vertical trough section 1014. The horizontal trough section 1013 is formed radially on the wall of the ring body positioning edge 104, and the vertical trough section 1014 is formed axially on the outer peripheral wall between the lower edge 105 of the ring body 1 and the ring body positioning edge 104.

[0069] In this embodiment, a drainage trough 101 is formed on the outer peripheral wall of the ring body 1 and located between the ring positioning edge 104 and the lower edge 105 of the ring body. The drainage trough 101 includes a horizontal trough section 1013 and a vertical trough section 1014. The horizontal trough section 1013 and the vertical trough section 1014 form a stepped structure on the outer peripheral wall of the balance ring, which facilitates the fixed assembly of the ring positioning edge 104 of the balance ring with the barrel body 4. At the same time, the horizontal trough section 1013 is the outlet of the drainage trough 101, and the vertical trough section 1014 is the inlet of the drainage trough 101. This also facilitates the entry of water in the barrel body 4 through the vertical trough section 1014 and the discharge through the horizontal trough section 1013.

[0070] It should be noted that the horizontal groove segment 1013 does not mean that the horizontal groove segment 1013 is geometrically perfectly horizontal. The horizontal groove segment 1013 can have a certain tilt angle relative to the horizontal direction. Similarly, the vertical groove segment 1014 does not mean that the vertical groove segment 1014 is geometrically perfectly vertical. The vertical groove segment 1014 can have a certain tilt angle relative to the vertical direction.

[0071] Optionally, such as Figure 2 and Figure 4 As shown, in one implementation of this embodiment, the balancing ring further includes at least one positioning part 2, which protrudes from the positioning edge 104 of the ring body. The positioning part 2 is used to insert into the positioning groove 301 on the barrel 4 of the fabric processing equipment to position the ring body 1 on the barrel 4.

[0072] In this embodiment, the two sides of the drainage trough 101 are divided into a first side 1011 and a second side 1012. The first side 1011 is provided with an inclined wall, while the second side 1012 can be provided with either the same inclined wall as the first side 1011 or a positioning part 2.

[0073] When the second side 1012 is provided with an inclined wall, and both the first side 1011 and the second side 1012 of the drain trough 101 are provided with inclined walls, the angle θ1 between the inclined wall of the first side 1011 and the horizontal plane and the angle θ2 between the inclined wall of the second side 1012 and the horizontal plane can be the same or different, thus forming a symmetrical or asymmetrical double-guide structure on both sides of the drain trough 101. During the dehydration process, when the washing water flows from the inner tub to the drain trough 101, it will be guided by the inclined walls on both sides of the drain trough 101. For example, when the angle between the inclined walls of the first side 1011 and the second side 1012 and the horizontal plane is set to 45°, after the washing water reaches the drain trough 101, the inclined walls on both sides will have the same guiding effect on the washing water, so that the washing water can be discharged from both sides of the drain trough 101 to the outside of the inner tub at the same flow rate and the same flow volume, which greatly increases the width of the drain channel and the drainage flow rate of the washing water. This double-sloping-wall design guides the flow path of the washing water more comprehensively, preventing water from accumulating on the non-sloping side of the drain trough 101. This further improves the uniformity and efficiency of drainage. The double-sloping-wall structure also makes the force on the balance ring more even, helping to maintain the overall balance of the washing machine during spin-drying and reducing vibration and noise. The combined effect of the two sloping walls on the washing water can also disperse the impact force of the washing water on the sides of the drain trough 101 to a certain extent, improving the structural strength of the balance ring.

[0074] With the positioning part 2 provided on the second side 1012, the positioning part 2 can achieve precise positioning and stable assembly of the balance ring and other components such as the tub body 4 in the inner tub assembly. During the installation of the balance ring onto the tub body 4, the positioning part 2 can cooperate with the corresponding positioning groove 301 and other positioning structures on the tub body 4 to quickly achieve the positioning of the balance ring, ensuring that the drain groove 101 can be accurately aligned with the drain channel of the tub body 4, avoiding drainage obstruction caused by installation deviations that prevent the washing water passing through the drain groove 101 from smoothly entering the drain channel. The cooperation between the positioning part 2 and the positioning structure can also enhance the connection strength between the balance ring and the tub body 4, reducing the risk of displacement or loosening of the balance ring under the huge centrifugal force generated by the high-speed rotation of the inner tub during dehydration, and ensuring the stable progress of the drainage process. The inclined wall of the first side 1011 of the drain groove 101 continuously plays a role in guiding and draining water throughout the entire dehydration process, enabling the positioning ring to simultaneously achieve the positioning function and the guiding and draining function, which not only improves the connection strength between the balance ring and the tub body 4, but also enhances the drainage effect of the inner tub, further enhancing the overall performance of the inner tub assembly.

[0075] By setting an inclined wall on the first side 1011 of the drainage channel 101 and selectively setting an inclined wall or a positioning part 2 on the second side 1012, the balance ring can not only further improve drainage efficiency through the double inclined wall structure, but also achieve precise and stable assembly with other components through the positioning part 2. This enhances the adaptability and practicality of the balance ring, thereby meeting different inner tub assembly requirements and expanding the application scenarios of the inner tub assembly.

[0076] Optionally, such as Figure 4 As shown, in one implementation of this embodiment, the positioning part 2 includes a first protruding rib 201 and a second protruding rib 202 spaced apart. The sidewall of the first protruding rib 201 away from the sidewall of the second protruding rib 202 and the sidewall of the second protruding rib 202 away from the sidewall of the first protruding rib 201 are used to insert into the groove where the assembly surface is located to position the ring 1 on the assembly surface.

[0077] In this embodiment, the positioning part 2 is composed of a first protruding rib 201 and a second protruding rib 202 arranged at intervals. The side wall of the first protruding rib 201 away from the second protruding rib 202 and the side wall of the second protruding rib 202 away from the first protruding rib 201 respectively cooperate with the two side walls of the groove on the assembly surface of the barrel 4, so that the positioning part 2 can be inserted into the groove on the barrel 4, thereby achieving the purpose of positioning the ring 1 on the assembly surface.

[0078] In one embodiment, the groove on the mounting surface is a rectangular groove, the cross-section of the first protrusion 201 and the second protrusion 202 is rectangular, and the spacing between the first protrusion 201 and the second protrusion 202 is adapted to the internal width of the rectangular groove, for example, as shown. Figure 4As shown, L1 is the width of the vertical cross-section of the groove, and L2 is the distance between the outer walls of the first protruding rib 201 and the second protruding rib 202. L1 > L2, allowing the first protruding rib 201 and the second protruding rib 202 to be inserted into the groove. When the balance ring is positioned and installed, the first protruding rib 201 and the second protruding rib 202 are simultaneously inserted into the rectangular groove. When the side wall of the first protruding rib 201 away from the second protruding rib 202 is tightly fitted with one inner wall of the rectangular groove, and the side wall of the second protruding rib 202 away from the first protruding rib 201 is tightly fitted with the other inner wall of the rectangular groove, and the ends of the first protruding rib 201 and the second protruding rib 202 both abut against the bottom wall of the rectangular groove, the positioning and installation of the balance ring is completed. The abutment between the positioning part 2 and the groove can limit the balance ring in the horizontal direction, preventing the balance ring from shifting left or right on the assembly surface. At the same time, this abutting fit can also limit the axial movement of the balance ring in the vertical direction to a certain extent, preventing the balance ring from being excessively squeezed towards the inner barrel by the workers during the installation process, thus causing it to deform greatly and improving the installation efficiency of the workers.

[0079] In another embodiment, the groove of the assembly surface is a trapezoidal groove, the opening width of which is smaller than the width of its bottom wall. The distance between the end of the first protruding rib 201 and the end of the second protruding rib 202 is greater than the distance between the root of the first protruding rib 201 and the root of the second protruding rib 202. The sidewalls of the first protruding rib 201 and the second protruding rib 202 that are away from each other correspond to the two inclined sidewalls of the trapezoidal groove, so that the overall outline of the positioning part 2 forms a trapezoidal structure that is adapted to the trapezoidal groove. When assembling the ring 1, the worker first applies relative pressure to the ends of the first protruding rib 201 and the second protruding rib 202 simultaneously to deform the first protruding rib 201 and the second protruding rib 202. When the distance between the ends of the first protruding rib 201 and the second protruding rib 202 is less than the opening width of the trapezoidal groove, the positioning part 2 is inserted into the trapezoidal groove until the ring 1 and the barrel 4 are fitted together. Then, the first protruding rib 201 and the second protruding rib 202 return to their initial positions. At this time, the side wall of the first protruding rib 201 away from the second protruding rib 202 is fitted with one inclined side wall of the trapezoidal groove, and the side wall of the second protruding rib 202 away from the first protruding rib 201 is fitted with the other inclined side wall of the trapezoidal groove. The distance between the ends of the first protruding rib 201 and the second protruding rib 202 is greater than the opening width of the trapezoidal groove. This trapezoidal structure offers superior self-locking properties. A certain amount of pressure and friction is generated between the positioning part 2 and the portion abutting the trapezoidal groove. Furthermore, the distance between the ends of the first protruding rib 201 and the second protruding rib 202 is greater than the opening width of the trapezoidal groove, thus creating a self-locking effect within the groove. This effectively reduces the risk of the balance ring dislodging from the groove due to vibration or centrifugal force during operation, further enhancing the stability of the balance ring. The trapezoidal positioning fit between the positioning part 2 and the groove ensures the positioning accuracy of the balance ring while also strengthening the connection between the balance ring and the inner tub. This allows the balance ring to remain stable in its installation position even under harsh operating conditions such as high-speed spin-drying in a washing machine, ensuring that wash water can be discharged promptly through the balance ring.

[0080] By designing the positioning part 2 with spaced-apart first protrusions 201 and second protrusions 202, the overall weight of the balance ring can be reduced, thereby reducing the overall energy consumption of the pulsator washing machine during operation. The spaced-apart first protrusions 201 and second protrusions 202 can also increase the sliding resistance between the positioning part 2 and the groove, effectively ensuring the positional accuracy of the ring 1 on the assembly surface, reducing the movement of the balance ring on the tub 4, and ensuring that the drain groove 101 and the drain channel of the tub 4 are always precisely aligned so that the washing water guided by the drain groove 101 can be quickly discharged from the inner tub, thus balancing the drainage performance and operational stability of the inner tub.

[0081] Example 2

[0082] like Figures 1 to 8 As shown, this embodiment provides an inner barrel assembly, including: the balance ring as in Embodiment 1;

[0083] The barrel body 4 has a balance ring mounted on its top. The horizontal groove section 1013 of the drainage groove 101 forms a first drainage channel with the top of the barrel body 4. The vertical groove section 1014 of the drainage groove 101 forms a second drainage channel with the inner wall of the barrel body 4. The first drainage channel and the second drainage channel together form a drainage channel connecting the inside and outside of the barrel body 4.

[0084] The water guiding part 102 and the top of the barrel body 4 form a through groove 103 with an inclined top, and the through groove 103 is connected to the horizontal groove section 1013.

[0085] In this embodiment, during the operation of the pulsator washing machine, it is necessary to drain the washing water inside the inner tub 4 in a timely manner to ensure the washing and dehydration effects on the fabrics. A balance ring is mounted on the top of the tub 4, and the horizontal section 1013 of the drain trough 101 forms a first drain channel with the top of the tub 4. The vertical section 1014 of the drain trough 101 forms a second drain channel with the inner wall of the tub 4. The first and second drain channels together form a drain channel connecting the inside and outside of the tub 4, allowing the washing water inside the tub 4 to flow out of the tub 4 along the drain channel under the centrifugal force generated by the rotation of the tub 4. Simultaneously, the inclined wall and the edge of the tub 4 form a through groove 103, which, as part of the drain trough 101, also communicates with the tub 4, effectively adding an additional drain channel between the tub 4 and the balance ring. During the dehydration stage, the inner tub rotates at high speed, and the washing water inside the tub 4 moves towards the tub wall under the action of centrifugal force. During this process, the water flow in the horizontal tank section 1013 is either directly discharged or quickly discharged from the inner tub under the guidance of the inclined wall, thereby accelerating the discharge of washing water; some water flows directly into the through tank 103 for discharge, further accelerating the discharge of washing water.

[0086] This design, featuring multiple interconnected drainage channels within a single drainage groove 101, significantly increases the flow area of ​​the inner tub assembly's drainage channels. This reduces resistance during washing water drainage, allowing the washing water inside the tub 4 to drain more quickly and smoothly. This reduces water residue accumulation at the balance ring, further lowering the risk of bacterial growth and improving the washing machine's hygiene, providing users with a healthier experience. Furthermore, the drainage groove 103 is formed by the inclined wall of the balance ring and the edge of the tub 4, eliminating the need for additional complex structural components. This improves drainage efficiency without increasing the manufacturing cost or overall weight of the inner tub assembly.

[0087] Since the inner tub assembly proposed in this embodiment includes the balance ring in Embodiment 1, the inner tub assembly in this embodiment has all the beneficial effects of the balance ring in Embodiment 1, and will not be described again.

[0088] Optionally, such as Figure 4 As shown, in one implementation of this embodiment, a positioning groove 301 is provided at the top of the barrel 4, and the positioning groove 301 is used to engage with the positioning part 2 on the balance ring.

[0089] In this embodiment, the positioning groove 301 is a rectangular groove, and the positioning part 2 is composed of a first protruding rib 201 and a second protruding rib 202 arranged at intervals. The side wall of the first protruding rib 201 away from the second protruding rib 202 and the side wall of the second protruding rib 202 away from the first protruding rib 201 respectively cooperate with the two side walls of the rectangular groove on the mounting surface of the barrel body 4, so that the positioning part 2 can be inserted into the rectangular groove. The cross-section of the first protruding rib 201 and the second protruding rib 202 is rectangular, and the spacing between the first protruding rib 201 and the second protruding rib 202 is adapted to the internal width of the rectangular groove. When positioning and installing the balance ring, the first protruding rib 201 and the second protruding rib 202 are simultaneously inserted into the rectangular groove. The balance ring is positioned when the sidewall of the first protruding rib 201 away from the second protruding rib 202 is tightly fitted against one inner wall of the rectangular groove, and the sidewall of the second protruding rib 202 away from the first protruding rib 201 is tightly fitted against the other inner wall of the rectangular groove. Furthermore, the ends of both the first and second protruding ribs 201 and 202 are abutting against the bottom wall of the rectangular groove. The abutting fit between the positioning part 2 and the rectangular groove limits the balance ring horizontally, preventing lateral displacement on the assembly surface. Simultaneously, this abutting fit also limits the axial movement of the balance ring vertically, preventing excessive compression of the balance ring towards the inner barrel during installation and thus improving installation efficiency.

[0090] In one embodiment, the positioning part 2 on the balance ring is an integrally formed rectangular protrusion, and the positioning groove 301 is a rectangular groove, with the rectangular protrusion fitting into the rectangular groove. When assembling the balance ring and the barrel 4, the operator aligns the rectangular protrusion with the rectangular groove and inserts it directly into the rectangular groove along the vertical direction, thereby achieving a snap-fit ​​connection between the ring 1 and the barrel 4. The integrally formed rectangular protrusion has a relatively simple processing technology, is easy to mass-produce, and is easy to maintain high dimensional accuracy, thus improving the assembly quality of the inner barrel assembly.

[0091] By opening a positioning groove 301 at the top of the barrel 4, it can be engaged with the positioning part 2 on the balance ring, thus achieving precise and stable assembly of the balance ring and the barrel 4. This not only improves the assembly efficiency and quality between the two, but also enhances the structural stability and reliability of the inner barrel assembly, ensures the smooth flow of the drainage channel, and further improves the overall working performance of the inner barrel assembly.

[0092] Optionally, such as Figure 7 and Figure 8 As shown, in one implementation of this embodiment, the inner tub assembly includes an inner tub bottom 3 assembled at the bottom end of the tub body 4;

[0093] A first protrusion 302 protruding into the interior of the barrel 4 is formed on the bottom wall of the barrel 4. The first protrusion 302 is constructed as a ring. The central axis of the first protrusion 302 is collinear with the central axis of the barrel 4. The first protrusion 302 is located above or below the outer periphery of the impeller on the barrel 4.

[0094] In this embodiment, the bottom wall of the inner barrel 4 is located below the impeller, and there is a gap between the bottom wall of the barrel 4 and the impeller. The central axis of the first protrusion 302 on the bottom wall of the barrel 4 coincides with the central axis of the barrel 4, and the root of the first protrusion 302 can be located below the outer periphery of the impeller, while the end of the first protrusion 302 can be higher than the outer periphery of the impeller.

[0095] In this embodiment, the width and height of the first protrusion 302 can be relatively large. For example, the width of the first protrusion 302 can be set to 5 cm and the height of the first protrusion 302 can be set to 3 cm. This allows the first protrusion 302 to be higher than the impeller and to form a water-gathering structure with a wider blocking range and a higher blocking height on the periphery of the impeller, so as to more effectively gather water flow.

[0096] During the washing stage, the rotation of the impeller drives the water flow and fabric movement within the tub 4. The water flow spreads outwards due to the impeller's rotation, while the first protrusion 302 forms a ring-shaped water-gathering structure on the outer periphery of the impeller, blocking the water flow. When the water flow reaches the outer periphery of the impeller, it stops spreading towards the edge of the tub 4 due to the obstruction of the first protrusion 302. The water flow is then deflected and gathers at the center of the tub 4 by the reaction force of the first protrusion 302. The gathered water flow has a larger volume and, driven by the impeller, generates a stronger water impact force. For thicker fabrics, the gathered, powerful water flow can penetrate the fabric more thoroughly, allowing for more complete cleaning and improving the water's stain-removing ability.

[0097] During the dehydration stage, the inner tub rotates at high speed. The higher protrusion height allows more water to be concentrated within the annular structure of the first protrusion 302. Therefore, under centrifugal force, most of the water flows from the center of the impeller towards the tub wall and is quickly discharged through drainage channels such as the drain holes. This reduces the occurrence of excessively long drainage paths at certain locations on the tub body due to excessive water diffusion, further improving the drainage speed of the inner tub assembly. Simultaneously, the wider protrusion width reduces the gap between the outer wall of the impeller and the tub body 4, significantly reducing the risk of fabric, buttons, or other small objects getting stuck in the gap between the impeller and the bottom wall of the tub body 4 during dehydration. This reduces fabric wear and tangling, while also lowering the failure rate of the impeller and the inner tub.

[0098] In addition, the first protrusion 302 can also serve as a reinforcing rib, which can enhance the structural strength of the bottom wall of the tub 4, improve the load-bearing capacity and service life of the tub 4, and enable the inner tub assembly to better adapt to the long-term high-intensity working environment of the washing machine.

[0099] By setting an annular first protrusion 302 on the bottom wall of the tub 4 below the outer periphery of the impeller, and making its central axis collinear with the central axis of the tub 4, the water flow is effectively concentrated, improving the washing effect on fabrics and the drainage efficiency of the inner tub assembly. Different sizes of the first protrusion 302 are designed according to different types of washing machines and different washing needs, enhancing the adaptability and practicality of the inner tub assembly, thus providing multiple guarantees for the stable and reliable operation of the inner tub assembly.

[0100] Optionally, such as Figure 7 and Figure 8 As shown, in one implementation of this embodiment, a second protrusion 303 is formed on the bottom 3 of the inner bucket and inside the first protrusion 302, protruding into the bucket body 4. The second protrusion 303 is constructed as a multi-segmented arc-shaped protrusion. A third protrusion 304 is formed on the bottom 3 of the inner bucket and inside the second protrusion 303, protruding into the bucket body 4. The third protrusion 304 is constructed as a frustum. Water collection areas 305 are formed between the second protrusion 303 and the third protrusion 304, and at the intervals of the second protrusion 303. First drain holes 306 are provided on the bottom wall of the bucket body 4 at intervals corresponding to the water collection areas 305.

[0101] In this embodiment, the second protrusion 303 is composed of four arc segments, each with a central angle of 90°. The spacing between adjacent arc segments and the diameter of the third protrusion 304 can be set according to different washing machine models. The four arc segments of the second protrusion 303 cooperate with the frustum-shaped third protrusion 304 to form more water-gathering areas 305. In addition to the annular water-gathering area 305 between the second and third protrusions 303 and 304, the four intervals between the four arc segments also become four water-gathering areas 305 respectively connected to the annular water-gathering area 305. This design can more effectively gather water flow, and even when the impeller rotates at low speed, sufficient water level can be formed in the water-gathering areas 305, thereby ensuring the washing effect on the fabric. During the spin-drying stage, the water flow in multiple water-gathering areas 305 can simultaneously flow to their respective first drain holes 306, making the drainage volume of the inner tub assembly greater and the drainage speed faster in the same period. Furthermore, the four-segment arc-shaped second protrusion 303 guides the water flow path more precisely, reducing disordered water flow, lowering the frictional resistance between the water flow and the bottom wall of the tub 4, and reducing the washing machine's energy consumption. The reasonable spacing also makes the distribution of the water collection area 305 and the first drain hole 306 more uniform, further improving the drainage uniformity and efficiency of the inner tub assembly.

[0102] Similarly, the second protrusion 303 and the third protrusion 304 can also serve as reinforcing ribs, which can enhance the rigidity of the bottom wall of the barrel 4 to a certain extent, thereby reducing the degree of deformation of the barrel 4 during high-speed rotation and extending the service life of the inner barrel assembly.

[0103] The second protrusion 303 and the third protrusion 304 of different sizes are designed according to different types of washing machines and different washing needs. The first drain hole 306 is opened at the corresponding position of the water gathering area 305. Multiple water gathering areas 305 can be formed at the bottom of the tub 4, which realizes the effective gathering and rapid discharge of water flow. At the same time, it improves the structural strength of the tub 4, reduces the energy consumption of the washing machine, and further improves the drainage efficiency and washing effect of the inner tub assembly.

[0104] Optionally, such as Figure 7 As shown, in one implementation of this embodiment, the first protrusion 302 has second drain holes 307 spaced apart on the side wall facing the central axis of the barrel 4.

[0105] In this embodiment, multiple second drain holes 307 can be provided, and these holes are evenly distributed along the annular sidewall of the first protrusion 302. During the washing process, some water flow will gather on the sidewall of the first protrusion 302 near the central axis of the tub 4, i.e., the side of the first protrusion 302 near the impeller. The water flow gathered in this area flows continuously under the stirring action of the impeller and can quickly flow through the second drain holes 307 to the side of the first protrusion 302 away from the impeller, participating in the overall water circulation, enhancing the overall water flow fluidity inside the washing machine, and improving the uniformity of fabric washing. During the spin-drying stage, the inner tub rotates at high speed, and some water flow inside the first protrusion 302 will tend to move towards the outer periphery of the bottom wall of the tub 4 under the action of centrifugal force. The second drain holes 307 provide a convenient discharge channel for these water flows, allowing them to be quickly discharged outside the inner tub, shortening the discharge path and improving drainage efficiency. The evenly distributed multiple second drain holes 307 also make the drainage of washing water more uniform, avoiding poor drainage at the bottom of the tub 4 due to local water accumulation.

[0106] In addition, the size of the second drain hole 307 can be customized according to the different needs of different washing machine models. For example, a smaller hole size can prevent fabric fibers or debris from entering the drain hole and causing blockage, ensuring smooth operation of the drain hole. A larger hole size makes it easier to clean and maintain later. When a small amount of debris enters the drain hole, it is easier to clean it, ensuring long-term unobstructed operation of the drain hole. It can also enhance the ventilation of the side wall of the first protrusion 302 to a certain extent, reduce the humid environment inside the tub 4, reduce the risk of bacterial growth, and improve the hygiene of the washing machine.

[0107] By opening second drain holes 307 at intervals on the side wall of the first protrusion 302 near the central axis of the tub 4, a new drainage channel is added to the bottom wall of the tub 4, further improving drainage efficiency and overall water flow. The diameter of the second drain hole 307 is specifically set according to the different needs of different washing machine models, which can prevent the drain hole from being blocked, facilitate later maintenance, expand the adaptability and versatility of the inner tub assembly, and make the inner tub assembly adaptable to different washing machine models, thereby reducing production costs.

[0108] Example 3

[0109] This embodiment provides a fabric processing device, including the inner tub assembly of Embodiment 2, wherein the tub body 4 is a non-perforated inner tub.

[0110] In this embodiment, the inner tub assembly from Embodiment 2 is used. Through the synergistic effect of the inclined wall of the balance ring, the drainage groove 101, the through groove 103, and the first protrusion 302, the second protrusion 303, the third protrusion 304, the water collection area 305, the first drainage hole 306, and the second drainage hole 307 on the bottom wall of the tub 4, the drainage efficiency of the inner tub assembly is greatly improved. During the dehydration stage, the washing water can be quickly and smoothly discharged from the tub 4 through multiple drainage channels, significantly reducing the moisture content of the fabric, shortening the drying time, and improving user convenience. Simultaneously, thorough drainage reduces residual moisture in the tub, lowering the possibility of bacterial growth, improving the hygiene of the fabric processing equipment, and providing users with a healthier fabric processing environment.

[0111] Since the fabric processing equipment proposed in this embodiment includes the inner tub assembly in Embodiment 2, the fabric processing equipment in this embodiment has all the beneficial effects of the inner tub assembly in Embodiment 2, and will not be described again.

[0112] Example 4

[0113] like Figure 9 As shown, this embodiment provides a control method for the fabric processing equipment in Embodiment 3. The method includes: when the fabric processing equipment is in the dehydration stage, controlling the motor of the fabric processing equipment to run for a first preset time and pausing for a second preset time, wherein the second preset time is less than the first preset time.

[0114] In this embodiment, the motor is controlled to run for a first preset time and then pause. The motor continues to run in a paused state for a second preset time and then restarts for the first preset time. This cycle is repeated until the dehydration stage ends. The second preset time is set to be shorter than the first preset time. This can prevent water from continuously adhering to the wall of the barrel and allow water to quickly pass through the drain hole, thereby improving the drainage efficiency of the inner barrel assembly.

[0115] For example, the first preset duration is set to 30 seconds, and the second preset duration is set to 10 seconds. During the 30 seconds of motor operation, the centrifugal force generated by the high-speed rotation of the inner tub separates water from the fabric, forming multiple water streams. Under the action of centrifugal force, these water streams move towards the tub wall and gradually exit the inner tub through the side drainage channels such as the drain groove 101, through groove 103, or drain hole located on the balance ring or tub perimeter wall. However, some of the water streams will continue to adhere to the tub perimeter wall under the action of centrifugal force and cannot move smoothly to the side drainage channel, or accumulate on the perimeter wall of the inner tub bottom 3 under the obstruction of the impeller and fabric, and cannot be discharged through the drain hole. The motor then pauses for 10 seconds. During this time, the rotation speed of the inner tub gradually decreases, and the centrifugal force weakens. Water that was originally attached to the tub wall but had not yet entered the side drainage channel, as well as water that had accumulated on the periphery of the bottom 3 of the inner tub due to the obstruction of the impeller and fabric, will flow downwards under the influence of gravity and enter the water collection area 305 on the bottom wall of the tub 4. Then, it will be discharged through the bottom drainage channels, such as the first drainage hole 306 and the second drainage hole 307 located in the water collection area 305. After the pause time reaches 10 seconds, the motor restarts and runs for 30 seconds, and this cycle repeats until the dehydration process is completed.

[0116] Setting the second preset time to be shorter than the first preset time ensures that the motor can continuously rotate to generate centrifugal force to separate water for most of the time, while the shorter pause time allows the remaining water to have enough time to flow to the bottom of the drum 4 and drain, thus mitigating the negative impact of continuous centrifugal force on water drainage. This intermittent rotation of the drum 4 significantly improves the drainage efficiency of the inner drum assembly, resulting in lower moisture content in the fabric. When the motor pauses, water that has not yet entered the side drainage channel will continue to drain out of the inner drum through the bottom drainage channel, so the brief pause of the motor will not affect the overall dehydration progress.

[0117] Furthermore, this control method can reduce motor energy consumption and wear to some extent. Continuous high-speed operation of the motor generates significant energy consumption and heat, while brief pauses allow the motor to rest, reducing heat accumulation and extending its lifespan. Simultaneously, the intermittent rotation of the drum 4 reduces vibration and noise of the inner drum assembly, improving the operational stability of the fabric processing equipment and enhancing the user experience.

[0118] In summary, the ingenious design of the balance ring and inner barrel assembly lies in:

[0119] First, by setting a water guide at the outlet of the drain tank, both water flow and foam are guided. Furthermore, the water guide is an inclined wall that transitions between the outlet sidewall of the drain tank and the positioning edge of the ring. This inclined wall allows the washing water to flow quickly along its slope and exit outside the balance ring. The gradually changing height of the inclined wall makes the flow path of the washing water smoother, reducing the resistance encountered by the washing water during discharge, lowering the risk of it accumulating and remaining at the balance ring, and accelerating the dehydration and discharge of water and foam from the balance ring, thus improving the dehydration efficiency of the pulsator washing machine. Simultaneously, the drain tank's use of the inclined wall to quickly and evenly discharge water outside the balance ring also helps maintain the operating balance of the pulsator washing machine during the dehydration process, thereby improving the overall operational stability and reliability of the machine.

[0120] Secondly, by limiting the angle θ between the inclined wall and the horizontal plane to within the range of 0° < θ < 90°, the guiding slope of the inclined wall is made more reasonable, further optimizing the discharge path of the washing water, enhancing the guiding effect of the balance ring, and effectively improving the drainage speed of the inner tub.

[0121] Third, by setting an inclined wall on the first side of the drainage channel and selectively setting an inclined wall or a positioning part on the second side, the balance ring can not only further improve drainage efficiency through the double inclined wall structure, but also achieve precise and stable assembly with other components through the positioning part. This enhances the adaptability and practicality of the balance ring, thereby meeting different inner tub assembly needs and expanding the application scenarios of the inner tub assembly.

[0122] Fourth, by designing the positioning part with spaced-apart first and second protrusions, the overall weight of the balance ring can be reduced, thereby reducing the overall energy consumption of the pulsator washing machine during operation. The spaced-apart first and second protrusions also increase the sliding resistance between the positioning part and the groove, effectively ensuring the positional accuracy of the ring on the assembly surface, reducing the balance ring's movement on the tub, and ensuring that the drain trough and the tub's drain channel remain precisely aligned. This allows the washing water guided by the drain trough to quickly drain from the inner tub, thus balancing the inner tub's drainage performance and operational stability.

[0123] Fifth, by opening a positioning groove at the top of the barrel, it can be engaged with the positioning part on the balance ring, thus achieving precise and stable assembly between the balance ring and the barrel. This not only improves the assembly efficiency and quality between the two, but also enhances the structural stability and reliability of the inner barrel assembly, ensures the smooth flow of the drainage channel, and further improves the overall working performance of the inner barrel assembly.

[0124] Sixth, by setting an annular first protrusion on the bottom wall of the tub below the outer periphery of the impeller, and making its central axis collinear with the central axis of the tub, the water flow is effectively concentrated, improving the washing effect on fabrics and the drainage efficiency of the inner tub assembly. Different sizes of the first protrusion are designed according to different types of washing machines and different washing needs, enhancing the adaptability and practicality of the inner tub assembly, thus providing multiple guarantees for the stable and reliable operation of the inner tub assembly.

[0125] Seventh, the second and third protrusions of different sizes are designed according to different types of washing machines and different washing needs, and the first drain hole is opened at the corresponding position of the water collection area. Multiple water collection areas can be formed at the bottom of the tub, realizing the effective collection and rapid discharge of water flow. At the same time, the structural strength of the tub is improved, the energy consumption of the washing machine is reduced, and the drainage efficiency and washing effect of the inner tub components are further improved.
