Description

Technical Field

[0001] The present invention belongs to the field of washing machines, and in particular relates to a washing tub assembly and a pulsator washing machine. Background Art

[0002] As people's quality of life improves, their expectations for washing machines are becoming increasingly higher. They often hope that the same washing machine can wash multiple types of clothing or that the clothes of different family members can be separated to prevent cross-contamination. However, if a user only has one washing machine at home, the washing tub needs to be cleaned before and after washing clothes for different family members or different types of clothes, which is a hassle.

[0003] To address this issue, existing solutions employ multiple wash tubs within a single washing machine. These tubs are detachably mounted within the washing machine, enabling separate washing zones. By leaving the middle and lower sections of the washing tubs blank, water can be stored independently for washing. Drain holes are provided on the outer peripheral wall of the upper opening, allowing water to drain from the dehydration holes when the washing tub rotates at high speed. This addresses the need for multiple washing zones within a single washing machine.

[0004] Chinese patent application number CN 201721197718.X discloses a washing tub assembly comprising an inner tub with a first open end and a structured body that mates with a middle tub; and a middle tub with a second open end and a balancing ring, the body of which mates with the inner tub. The inner tub's walls are tilted outward at a predetermined angle. The inner tub is removably connected to the middle tub, and the two tubs engage and mate, allowing them to rotate synchronously. The inner tub is replaceable, allowing each user to use their own. During the washing process, the inner tub forms an independent space, isolating the clothes, ensuring cleanliness and hygienic safety. However, while this solution allows for a replaceable washing tub, the addition of the middle tub complicates the structure and increases the cost. Furthermore, the inner tub's water level cannot be automatically sensed when water enters the inner tub, relying instead on a water level valve to detect water inflow, which is inaccurate and wastes water and electricity.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology. The purpose is to provide a washing bucket assembly, which moves in and out of the outer bucket through a moving part, so that it moves inward through the mounting hole on the support frame and extends into the water permeable hole to communicate with the inner bucket while blocking the water permeable hole. The liquid level detection device is connected to the interior of the inner bucket through the moving part, which facilitates the detection of the water level in the inner bucket, makes the detection result more accurate, saves water and electricity, and has a simple structure.

[0034] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0035] (1) The present invention allows a moving part to move inwards and extend into the mounting hole, closing the water-permeable hole, and at the same time, connect the cavity inside the moving part with the interior of the inner barrel during the water filling process of the washing machine with a hole-free inner barrel. The liquid level detection device outside the outer barrel is connected with the washing water inside the inner barrel through the cavity of the moving part.

[0036] (2) The present invention sets a water-stopping component in the water-permeable hole. In the initial state, the water-stopping component closes the water-permeable hole of the inner barrel. When water needs to be admitted to detect the water level, the movable component moves inward to penetrate the installation hole and push the water-stopping component in the water-permeable hole to open the water-permeable hole, so that the cavity is connected with the inner barrel and the water-permeable hole of the inner barrel is closed at the same time to prevent the inner barrel from leaking. When the water level of the inner barrel does not need to be detected, the movable component can be moved outward to exit the water-permeable hole, and the water-stopping component can be used to close the water-permeable hole, so that the inner barrel can complete dehydration and other tasks.

[0049] It should be noted that these drawings and textual descriptions are not intended to limit the conceptual scope of the present invention in any way, but rather to illustrate the concept of the present invention for those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0051] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0053] like Figures 1 to 9 As shown, the washing tub assembly of the present invention can be used in a pulsator washing machine, and the washing tub assembly includes an inner tub 1, a support frame 2, and an outer tub 4, which are sequentially arranged. The inner tub 1 is a non-porous inner tub 1, that is, the inner tub 1 can hold water, and water will not enter between the inner tub 1 and the outer tub 4 during washing.

[0054] The peripheral wall of the open end of the inner tub 1 is provided with a dehydration hole 11, and the dehydration hole 11 is provided on the peripheral wall of the inner tub 1 above the highest water level. The support frame 2 has a accommodating cavity and an opening at one end. The inner tub 1 is detachably arranged in the accommodating cavity through the opening, and is circumferentially limited with the support frame 2 so that the support frame 2 rotates to drive the inner tub 1 to rotate, making it convenient to remove the inner tub 1 from the support frame 2. When the washing machine dehydrates, the water flow rises along the inner peripheral wall of the inner tub 1 and is discharged through the dehydration hole 11. It is possible to wash different clothes in separate tubs or one person can wash in one inner tub to avoid mixed washing. The inner tub 1 and the support frame 2 are synchronously and rotatably arranged in the outer tub 4.

[0055] The bottom of the inner tub 1 and the support frame 2 are provided with corresponding water-permeable holes 12 and mounting holes 21. The movable member 5 has a cavity within it and is movably disposed inwardly and outwardly within the outer tub 4. The movable member 5 is configured to penetrate the mounting hole 21 inwardly and then seal the water-permeable hole 12, thereby achieving both a seal with the inner tub 1 and communication with the interior of the inner tub 1. Alternatively, the movable member can be moved outwardly to disconnect from the inner tub 1, sealing the inner tub 1. The liquid level detection device 6 is connected to the movable member 5 and is configured to communicate with the inner tub 1 through the movable member 5 to detect the liquid level within the inner tub 1.

[0056] The present invention enables the movable component 5 to move inwardly and extend into the mounting hole 21, closing the water-permeable hole 12, and at the same time communicating the cavity inside the movable component 5 with the interior of the inner barrel 1 during the water filling process of the washing machine with a hole-free inner barrel 1. The liquid level detection device 6 outside the outer barrel 4 is communicated with the washing water inside the inner barrel 1 through the cavity of the movable component 5. The liquid level can be detected in real time during the water filling and washing process of the inner barrel 1, and the water intake of the inner barrel 1 can be accurately controlled, thereby saving water and electricity and having a simple structure.

[0057] For example, before water enters the inner tub 1, the movable part 5 is controlled to move inward so that the movable part 5 blocks the water hole 12, and the water inlet 511c of the cavity on the end of the movable part 5 extends into the water hole 12 or the water hole 12 is penetrated and extends into the inner tub 1, communicating with the interior of the inner tub 1, and then the washing machine is controlled to let water into the inner tub 1.

[0058] like Figures 2 to 6 As shown, a water-stopping member 3 is provided in the water-permeable hole 12 for opening or closing the water-permeable hole 12. The movable member 5 includes a connecting pipe assembly 51, which is arranged in the outer tub 4 and can be moved inward and outward. Preferably, no other drainage outlet is provided at the bottom of the inner tub 1, and drainage is only conducted through the dehydration hole 12.

[0059] One end of the connecting pipe assembly 51 is located in the outer tub 4 and can be moved inward to penetrate the mounting hole 21, thereby closing the water hole 12 and driving the water stop member 3 to move and open the water hole 12, thereby connecting the cavity with the inner tub 1. Alternatively, the connecting pipe assembly 51 can be moved outward to cause the water stop member 3 to close the water hole 12.

[0060] The other end of the connecting pipe assembly 51 is located outside the outer barrel 4 and is connected to the liquid level detection device 6 .

[0061] The present invention provides a water-stopping component 3 in the water-permeable hole 12. In the initial state, the water-stopping component 3 closes the water-permeable hole 12 of the inner tub 1. When water needs to be admitted to detect the water level, the movable component 5 is moved inward to penetrate the mounting hole 21, push open the water-permeable hole 12, and open the water-permeable hole 12, so that the cavity is connected with the inner tub 1, and at the same time, the water-permeable hole 12 of the inner tub 1 is closed to prevent the inner tub 1 from leaking. When the water level of the inner tub 1 does not need to be detected, the movable component 5 can be moved outward to exit the water-permeable hole 12, and the water-stopping component 3 can be used to close the water-permeable hole 12, so that the inner tub 1 can complete dehydration and other tasks.

[0062] The water-stopping member 3 may be disposed in the water-permeable hole 12, and the movable member 5 may be sealed and penetrate the water-stopping member 3. The water-stopping member 3 may also be movably disposed inwardly or outwardly in the water-permeable hole 12, and the movable member 5 may drive the water-stopping member 3 to move inwardly or outwardly to open the water-permeable hole 12, extend into the water-permeable hole 12 to communicate with the inner tub 1, and simultaneously close the water-permeable hole 12 with its own structure.

[0063] Preferably, the water-stopping component 3 is movably disposed in the water-permeable hole 12 .

[0064] The water stop member 3 includes a water stopper and a first spring 34. A mounting bracket 121 is provided in the water permeable hole 12. The mounting bracket 121 has a space in the axial direction to accommodate water flow. The water stopper is axially movably fixed in the mounting bracket 121.

[0065] The water stopper includes a plug 32, a connecting rod 31, and a mounting platform 33, which are connected in sequence. The connecting rod 31 is movably inserted into the mounting frame 121. One end of the connecting rod 31 has a plug 32, which is provided at the inner end of the water hole 12 and is used to close or open the water hole 12. The other end of the connecting rod 31 has a mounting platform 33, which is movably located in the water hole 12. The mounting platform 33 can be pressed against or released from the connecting pipe assembly 51. The outer diameters of the mounting platform 33 and the plug 32 are larger than the outer diameter of the connecting rod 31. The first spring 34 is sleeved on the outer circumference of the connecting rod 31 and pressed between the mounting platform 33 and the mounting frame 121.

[0066] In the initial state, the plug of the water stopper closes the inner end of the water hole 12; when detecting the water level of the inner barrel 1, the movable component 5 presses the mounting platform 33 to move inward, compressing the first spring 34, so that the plug head 32 moves away from the inner end of the water hole 12 to open the water hole 12; when the water level detection is completed, the movable component 5 moves outward, the mounting platform 33 loses its pressure, the first spring 34 resets and drives the water stopper to move outward, closing the inner end of the water hole 12, and the inner barrel 1 can hold water alone.

[0067] The diameter of the mounting hole 21 gradually decreases from the outside to the inside and is larger than the inner diameter of the water hole 12 , so as to facilitate guiding one end of the connecting pipe assembly 51 to move inward through the mounting hole 21 to the water hole 12 .

[0068] Preferably, the plug 32 is cylindrical.

[0069] The mounting platform 33 is provided with a plurality of water-permeable notches. These notches extend inward from the outer periphery of the mounting platform 33, passing through both sides of the mounting platform 33. Water in the inner tub 1 can flow outward through these notches. More preferably, the mounting platform 33 is a circular cone, and the number of these notches is three, spaced apart along the circumference of the mounting platform 33.

[0070] Furthermore, one end of the connecting tube assembly 51 is provided with a water inlet 511c, which can extend into the water permeable hole 12. An annular sealing lip 511d is provided at one end of the connecting tube assembly 51, located around the outer periphery of the water inlet 511c. When the end of the connecting tube assembly 51 extends inwardly into the water permeable hole 12, it presses against the water-stopping member 3 and seals the outer end of the water permeable hole 12 when the end is moved. Of course, the annular sealing lip 511d can also extend into the water permeable hole 12 to seal the water permeable hole 12.

[0071] Preferably, one end of the connecting tube assembly 51 is provided with a ball seat 511a, in which the ball 511b is rotatably mounted. The water inlet 511c is provided on the ball seat 511a, peripherally of the ball 511b. The water inlet 511c communicates with the internal cavity and, when the water-stop component 3 opens the water-permeable hole 12, enables communication with the interior of the inner tub 1. The annular sealing lip 511d is fixed to the outer peripheral wall of the connecting tube assembly 51 below the water inlet 511c, extending radially outward and then upward to the periphery of the water inlet 511c.

[0072] The connecting pipe assembly 51 is an internally connected connecting pipe assembly 51. Before water enters, the connecting pipe assembly 51 moves upward to press against the bottom plate 23 outside the support frame 2. The ball 511b at one end of the connecting pipe assembly 51 starts to roll along the bottom plate 23 of the support frame 2 after the inner barrel 1 rotates. When encountering the mounting hole 21, one end of the connecting pipe assembly 51 continues to move upward and extend into the mounting hole 21. The ball 511b lifts the water-stop component 3. The water inlet 511c on the outer periphery of the ball 511b is connected to the inner end of the water permeable hole 12. The interior of the connecting pipe assembly 51 is connected to the water in the inner barrel 1. The annular sealing lip 511d below the water inlet 511c seals the outer end of the water permeable hole 12 to prevent the water in the inner barrel 1 from flowing out, so that the water in the inner barrel 1 enters the liquid level detection device 6 through the interior of the connecting pipe assembly 51, and the water level in the inner barrel 1 can be detected.

[0073] More preferably, the cavity is extended along the axis in the connecting pipe assembly 51, and the extension direction of the water inlet 511c is set at an angle to the axial direction of the connecting pipe assembly 51, extending inwardly from the outer periphery of the ball 511b to the cavity.

[0074] Two annular projections are provided on the outer circumferential wall of one end of the connecting tube assembly 51. These projections are positioned adjacent to the ball seat 511a and spaced axially apart to form a clamping groove. The annular sealing lip 511d is clamped within the clamping groove. The outer diameter of the annular projection is smaller than the inner diameter of the mounting hole 21.

[0075] Furthermore, the connecting pipe assembly 51 includes a connecting pipe 511 , a supporting pipe 512 and a telescopic sleeve 516 .

[0076] The bottom wall of the outer tub 4 is provided with a through-hole 41, corresponding to the mounting hole 21 of the support frame 2. A sealing plug 44 is provided in the mounting hole 41. The connecting tube 511 is sealably and removably inserted into the sealing plug 44 on the bottom wall of the outer tub 4 to prevent water leakage from the outer tub 4. The ball seat 511a is provided at one end of the connecting tube 511, located within the outer tub 4.

[0077] The support tube 512 is located outside the outer barrel 4. One end of the support tube 512 is sleeved and fixed to the outer periphery of the other end of the connecting tube 511. The support tube 512 is connected to the connecting tube 511 and can be pressed against the sealing plug 44. The other end of the support tube 512 is connected to the liquid level detection device 6.

[0078] Preferably, a locking protrusion is provided on the outer peripheral wall of the other end of the connecting tube 511 and is locked in the locking groove of one end of the supporting tube 512. The width of the ball seat 511a is substantially the same as the radial outer diameter of the connecting tube 511.

[0079] The telescopic sleeve 516 is mounted on the outer periphery of the connecting tube assembly 51 located outside the outer tub 4. Specifically, one end of the telescopic sleeve 516 has a first connection seat 514, which is sealed and fixed to the bottom of the outer tub 4 around the outer periphery of the connecting tube 511. The other end of the telescopic sleeve 516 has a second connection seat 515, which is sealed and fixed to the outer peripheral wall of one end of the support tube 512.

[0080] The connecting pipe 511 and the support pipe 512 are straight-through pipes. The connecting pipe 511 is dynamically sealed and penetrates the bottom wall of the outer barrel 4. The outer diameter of one end of the support pipe 512 is larger than the outer diameter of the connecting pipe 511 and larger than the inner diameter of the mounting port 41, which can play a limiting role to prevent the support pipe 512 from penetrating into the outer barrel 4. One end of the telescopic sleeve 516 is fixed to the bottom wall of the outer barrel 4 outside the mounting port 41, and the other end is fixed to the support pipe 512. It moves with the support pipe 512 outside the outer barrel 4, and can take over the water leakage at the mounting port 41 of the outer barrel 4, thereby further preventing water leakage.

[0081] The connecting pipe assembly 51 further includes a second spring 517 . One end of the second spring 517 is sandwiched between the outer circumferential wall of the other end of the connecting pipe 511 and the inner circumferential wall of one end of the support pipe 512 , and the other end presses into the other end of the support pipe 512 .

[0082] Specifically, the other end of the connecting tube 511 has a downwardly protruding annular platform located below the latching protrusion. One end of the second spring 517 is sleeved around the outer circumference of the annular platform, and the other end presses against the stop block 518 inside the other end of the support tube 512, thereby supporting and stabilizing the connecting tube 511.

[0083] The liquid level detection device 6 is disposed outside the outer barrel 4 and includes an air chamber 61 , a liquid level sensor 63 and a pressure pipe 62 .

[0084] The connecting pipe assembly 51 includes a bellows 513, one end of which is connected to the other end of the support pipe 512. The other end of the bellows 513 is connected to the air chamber 61. The liquid level sensor 63 is located near the barrel opening of the outer barrel 4 and is connected to the air chamber 61 via a pressure-conducting pipe 62.

[0085] After the water in the inner barrel 1 is connected to the connecting pipe assembly 51, the water enters the air chamber 61 through the connecting pipe 511, the support pipe 512, and the bellows 513 in sequence, and the compressed air enters the liquid level sensor 63 through the pressure pipe 62 to sense the water level pressure and control the water intake.

[0086] Furthermore, the washing tub assembly further includes a fixing frame 42 and a driving module 52 .

[0087] The fixing bracket 42 is disposed below the bottom of the outer tub 4. A certain distance exists between the fixing bracket 42 and the mounting opening 41 at the bottom of the outer tub 4. The other end of the support tube 512 passes through the fixing bracket 42. The driving module 52 is disposed on the fixing bracket 42 outside the outer tub 4. The driving module 52 is in driving connection with the other end of the support tube 512 to drive the connecting tube assembly 51 inward and outward movement.

[0088] The present invention sets a fixing frame 42, and the other end of the support tube 512 is movably inserted into the fixing frame 42, which can support and stabilize the connecting pipe assembly 51. The driving module 52 is fixed on the fixing frame 42 to facilitate the control of the connecting pipe assembly 51 to move up and down.

[0089] Preferably, the drive module 52 further includes a motor 521 and a transmission rod assembly. The motor 521 is disposed at the bottom of the fixing frame 42 and is in driving connection with the other end of the connecting pipe assembly 51 that protrudes downward from the fixing frame 42 via the transmission rod assembly. A recessed cavity is formed on the bottom wall of the outer barrel 4, and the mounting opening 41 is disposed within the recessed cavity. The fixing frame 42 is a transversely disposed fixing plate that extends from the edge of the cavity toward the opening of the cavity.

[0090] The second connecting seat 515 is sleeved and connected to one end of the support tube 512 that protrudes upward from the fixing frame 42. The telescopic sleeve 51 is located between the bottom wall of the cavity and the fixing plate.

[0091] The transmission rod assembly includes an eccentric cam 522 and a connecting shaft 523. The eccentric cam 522 is connected to the output shaft of the motor 521. The eccentric cam 522 is connected to the outer circumferential wall of the support tube 512 via the connecting shaft 523. The connecting shaft 523 includes a first connecting shaft and a second connecting shaft. One end of the first connecting shaft is connected to the eccentric output end of the eccentric cam 522, and the other end extends upward. The second connecting shaft is connected between the other end of the first connecting shaft and the outer circumferential wall of the other end of the support tube 512.

[0092] Furthermore, the bottom of the inner tub 1 has a flange 13. The water-permeable hole 12 extends outward and protrudes from the flange 13. The edge of the flange 13 is provided with a support foot 131 that protrudes toward the bottom plate 23 of the support frame 2. The support foot 131 extends downward beyond the water stopper. The bottom plate 23 within the support frame 2 has an annular cavity 231, into which the support foot 131 is inserted.

[0093] The present invention sets the water-permeable hole 12 on the flange 13, and the support feet 131 on the outer periphery of the flange 13 extend downward beyond the water stop plug, which can not only increase the strength of the inner drum 1 of the washing machine, but also enable the inner drum 1 to be placed stably on the ground during assembly or transportation, and also protect the water stop plug to avoid damage to the water stop plug.

[0094] like Figure 7 As shown, the ball 511b is located directly below the circular rotation track generated by the mounting hole 21 as the support frame 2 rotates, and is used to slide along the circular rotation track and enter the mounting hole 21.

[0095] Since the inner barrel 1 is rotatable, the ball 511b of the connecting pipe assembly 51 is arranged directly below the circular rotation trajectory of the mounting hole 21. When water needs to be added, it is only necessary to control the movable part 5 to move upward until it is against the bottom plate 23 of the support frame 2, and then control the inner barrel 1 to rotate slowly so that the ball 511b moves relative to the circumferential trajectory on the support frame 2 where the mounting hole 21 is located, and gradually moves into the mounting hole 21. Then continue to control the movable part 5 to move upward, and the ball 511b presses open the water-stop part 3 to connect with the inner barrel 1 while closing the water-permeable hole 12.

[0096] Preferably, the mounting hole 21 is provided on the bottom plate 23 of the support frame 2, offset from the center of the tub bottom. A slideway 232 is provided on the bottom plate 23 outside the support frame 2. The mounting hole 21 is provided on the slideway 232, which extends circumferentially. When the inner tub 1 rotates, the ball 511b slides along the slideway 232 into the mounting hole 21 and presses against the water stopper.

[0097] In the present invention, a water-stopping component 3 that can move inward and outward is fixed in the water-permeable hole 12, a slide 232 is set on the bottom plate 23 of the support frame 2, and the mounting hole 21 is set on the slide 232, opposite to the water-permeable hole 12; the washing tub assembly is installed in the washing machine, and the ball 511b of the moving component 5 of the washing machine slides along the slide 232 outside the support frame 2 into the mounting hole 21, and continues to move inward to drive the water-stopping component 3 to move inward, opening the inner end of the water-permeable hole 12, so that the moving component 5 of the washing machine can be quickly positioned and guided into the mounting hole 21 to quickly open or close the water-permeable hole 12, thereby reducing the difficulty of operation and improving the operating efficiency.

[0098] like Figures 8 and 9 As shown, the inlet end of the support frame 2 is lower than the open end of the inner tub 1. By adding the support frame 2, the present invention can rotatably fix the support frame 2 in the outer tub 4 of the washing machine, and detachably fix the inner tub 1 in the support frame 2, thereby reducing the space occupied by the support frame 2 in the washing machine. The support frame 2 can also play the role of fixing the inner tub 1. The structure is small in volume and low in cost. It can be realized that the inner tub 1 can be replaced and the clothes can be washed separately to avoid cross infection.

[0099] Preferably, the axial height of the support frame 2 is much smaller than the axial height of the inner tub 1. The barrel body of the inner tub 1 is arranged in a bell-mouthed tilted manner so that the water in the inner tub 1 can be easily discharged during dehydration.

[0100] The inner circumference of the accommodating cavity of the support frame 2 is provided with protrusions 22 extending to both axial ends. A recessed chute 14 is provided on the outer circumferential wall of the inner tub 1, extending axially. This chute 14 slides from the inlet end of the accommodating cavity and engages with the protrusion 22 within the support frame 2, facilitating quick assembly and disassembly of the inner tub 1 and the support frame 2 while preventing the inner tub 1 from rotating circumferentially relative to the support frame 2, thereby preventing rotation, displacement, and shaking.

[0101] A balance ring 26 is provided at the inlet end of the support frame 2, and the balance ring 26 is lower than the opening end of the inner tub 1, which lowers the center of gravity of the support frame 2 and the inner tub 1, and can also reduce the upper space occupied by the balance ring 26, thereby increasing the washing capacity of the inner tub 1.

[0102] The support frame 2 includes a base plate 23 , a plurality of connecting arms 25 and an annular arm 24 .

[0103] One end of a plurality of connecting arms 25 is circumferentially spaced apart on the outer peripheral edge of the bottom plate 23, and the other end extends axially or toward the opening of the inner tub 1. The annular arm 24 is connected to the other ends of the plurality of connecting arms 25 to form the accommodating cavity. The protrusion 22 is provided on the inner side of the connecting arm 25. Preferably, the protrusion 22 protrudes inward from the connecting arm 25 and the annular arm 24 at the connection point.

[0104] The chute 14 of the inner tub 1 extends from the bottom of the tub to the open end. The inner circumferential wall of the inner tub 1 is provided with a recessed guide portion extending obliquely from the bottom of the inner tub 1 toward the open end, guiding water from the bottom of the inner tub 1 toward the dewatering hole 11. The inner circumferential wall of the inner tub 1 is provided with multiple guide portions spaced circumferentially. These guide portions protrude outward from the inner circumferential wall of the inner tub 1, forming the chute 14 on the outer wall of the inner tub 1 between two adjacent guide portions.

[0105] Furthermore, the height of the support frame 2 is lower than the height of the dehydration hole 11 of the inner tub 1 , which can facilitate the dehydration of the inner tub 1 and prevent water released from the dehydration hole 11 from being reflected onto the support frame 2 and causing splashing.

[0106] Preferably, the height of the support frame 2 is lower than half the height of the inner barrel 1, which can provide sufficient circumferential support to prevent the inner barrel 1 from shaking in the circumferential direction and also have sufficient strength in the axial direction.

[0107] The specific height may be that the upper end of the support frame 2 is higher than a quarter of the height of the inner tub 1 and lower than three quarters of the height of the inner tub 1 .

[0108] More preferably, the upper edge of the support frame 2 can be higher than half the height of the inner barrel 1 and lower than three-quarters of the height of the inner barrel 1, or the upper edge of the support frame 2 can be higher than one-quarter the height of the inner barrel 1 and lower than half the height of the inner barrel 1.

[0109] The present invention also provides a pulsator washing machine (not shown in the figures) having any of the above-mentioned washing tub assemblies.

[0110] The washing machine also includes a pulsator and a deceleration clutch 72. The deceleration clutch 72 is fixed to the outside of the bottom of the outer tub 4. The pulsator is rotatably disposed within the inner tub 1 via a pulsator shaft. The support frame 2 and the inner tub 1 are rotatably disposed within the outer tub 4 via a spin shaft.

[0111] The dehydration shaft is sleeved around the output shaft of the deceleration clutch 72, then extends from the outside into the outer tub 4, connecting to the support frame 2 and inner tub 1. The output shaft of the deceleration clutch 72 extends through the dehydration shaft, with external splines at its upper end, which mate with the internal splines at the lower end of the impeller shaft. The upper end of the impeller shaft extends into the inner tub 1, with external splines at its upper end, which mate with the impeller lining.

[0112] The washing machine further includes a drain valve 71 , which is disposed outside the bottom of the outer tub 4 and is used to drain water in the outer tub 4 .

[0113] The washing machine further comprises a housing, which includes an upper control panel, the control panel being provided with a clothing loading port. An outer tub cover 43 is located below the control panel, and can be opened to allow clothing to be loaded into the inner tub 1 for washing. The outer tub cover 43 also prevents water from splashing outward from the inner tub 1 during the washing or dehydration process.
