Description

Washing tub assembly and pulsator washing machine 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 lower and middle 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 chamber, isolating the clothes from the washing process, ensuring cleanliness and hygienic safety. However, while this solution is replaceable, the addition of the middle tub complicates the structure and increases the cost. Furthermore, during dehydration in the inner tub, the water flows slowly along the inner tub's walls, resulting in low dehydration efficiency.

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

[0006] Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome at least one of the shortcomings of the prior art. The purpose is to provide a washing tub assembly, wherein a guide portion is added inside the inner tub, and a dehydration hole is provided at a balance ring near the top of the inner tub. When the inner tub rotates for dehydration, the first side wall in the extension direction of the guide portion is utilized to guide the water in the inner tub obliquely upward to the dehydration hole, thereby achieving rapid dehydration and improving dehydration efficiency. The structure has low cost, can also increase the washing effect, and improve the cleaning ratio.

[0008] Another object of the present invention is to provide a washing tub assembly, with an additional support frame, a guide portion protruding from the inner side of the inner tub to the outer side to form a protrusion, and a slide groove formed between adjacent protrusions on the outer side of the inner tub. The bottom end of the inner tub can be slidably engaged with the protrusion in the support frame. The setting of the guide portion can not only guide the water flow for dehydration on the inner side of the tub, but also can be conveniently quickly disconnected from the support frame on the outer side of the inner tub. The structural design is ingenious, the processing is convenient, and the structural cost is low.

[0009] Another object of the present invention is to provide a pulsator washing machine.

[0010] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is to provide a washing bucket assembly, comprising:

[0011] The inner barrel has a balance ring at the open end and a dehydration hole on the peripheral wall above the highest water level;

[0012] The inner wall of the inner barrel is provided with a recessed guide portion, which extends from the bottom of the inner barrel toward the open end. The first side wall on one side of the extension direction of the guide portion is inclined and extended to guide water to flow toward the dehydration hole during dehydration.

[0013] The invention provides a recessed guide portion on the inner circumference of a non-perforated inner tub. The guide portion extends obliquely from the bottom of the inner tub toward the first sidewall extending toward the open end. During dehydration, water in the tub, under the action of centrifugal force, rises gradually along the inclined first sidewall within the guide portion and is discharged from the dehydration hole at the inner tub's open end, significantly improving the dehydration rate. During washing, the protruding sidewall within the guide portion also enhances cleaning performance. Furthermore, a balance ring on the open end of the inner tub prevents water from overflowing along the first sidewall.

[0014] Furthermore, the guide portion extends from the bottom of the inner tub to the dehydration hole of the inner tub, and the first side wall of the guide portion extends obliquely into the dehydration hole.

[0015] Furthermore, the inclination direction of the first side wall of the guide portion is opposite to the dehydration rotation direction of the inner tub;

[0016] Preferably, the inclination angle between the first side wall of the guide portion and the horizontal plane is 20°-80°.

[0017] Furthermore, the second side wall on the other side of the extension direction of the guide portion is extended vertically from the bottom of the inner barrel along the axial direction toward the open end of the inner barrel;

[0018] During the process of the guide portion extending toward the open end, the first side wall of the guide portion extends obliquely and gradually moves away from the second side wall of the guide portion.

[0019] Furthermore, the inner barrel includes a barrel bottom wall and a cylinder with openings at both ends, the barrel bottom wall and the cylinder are integrally injection-molded, and the guide portion is arranged on the inner circumferential wall of the cylinder.

[0020] Furthermore, the bottom of the balance ring is fixed to an opening at one end of the inner barrel, and the dehydration hole is arranged close to the balance ring;

[0021] The portion of the bottom wall of the balance ring that protrudes inwardly from the opening is a guide plate, which extends inwardly and downwardly from the inner peripheral wall of the opening to the dehydration hole.

[0022] Furthermore, part of the bottom wall of the balance ring protrudes outward from the outer peripheral wall of the open end of the inner barrel;

[0023] The balance ring is further provided with a water baffle, which extends downward from the outer ring end of the bottom wall of the balance ring and is arranged beyond the dehydration hole.

[0024] Furthermore, it further comprises: a support frame having an accommodating cavity, wherein the other end of the inner barrel is detachably fixed in the accommodating cavity of the support frame and is circumferentially limited with the support frame;

[0025] Preferably, the upper edge of the support frame is lower than the height of the dehydration hole of the inner barrel, the inner circumferential side of the accommodating cavity of the support frame has a protrusion extending to both axial ends, and the outer circumferential wall of the bottom end of the inner barrel is provided with a recessed sliding groove, which is slidably engaged with the protrusion in the support frame.

[0026] Furthermore, a plurality of dehydration holes are provided on the peripheral wall of the open end of the inner barrel at intervals along the circumferential direction, and the inner barrel is provided with a plurality of guide portions provided at intervals along the circumferential direction;

[0027] The guide portion protrudes from the inner side of the inner barrel to the outer side to form a protrusion, and the concave portion between adjacent protrusions on the outer side of the inner barrel forms the slide groove;

[0028] Preferably, the sliding groove extends from the bottom of the inner barrel to the open end with an inner diameter gradually decreasing, and slides from top to bottom to be clamped on the protrusion.

[0029] The present invention also provides a pulsator washing machine having any of the above-mentioned washing tub assemblies.

[0030] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0031] (1) The invention provides a recessed guide portion on the inner circumferential wall of the non-porous inner tub. The guide portion extends obliquely from the first side wall extending from the bottom of the inner tub toward the open end. When the inner tub rotates for dehydration, the water in the tub, under the action of centrifugal force, tends to gradually rise along the inclined first side wall in the guide portion and be discharged from the dehydration hole at the open end of the inner tub, greatly improving the dehydration rate. During washing, the protruding side wall in the guide portion can also improve the cleaning performance. In addition, the balance ring on the open end of the inner tub can prevent the water rising along the first side wall from overflowing.

[0032] (2) The present invention has a water baffle extending downward from the outer ring end of the bottom wall of the balance ring. The water baffle extends downward and is arranged to exceed the dehydration hole. When the washing machine is a double-barrel washing machine, the inner barrel is arranged in the outer barrel. There is no water between the inner barrel and the outer barrel during washing. When the inner barrel is dehydrated, after the water is discharged from the dehydration hole, the water can be discharged directly downward through the outer barrel, which can prevent the discharged water from hitting the outer barrel and splashing.

[0033] (3) The present invention adds a support frame, which can be rotatably fixed in the outer barrel of the washing machine, and the bottom end of the inner barrel can be detachably fixed in the support frame, thereby reducing the space occupied by the support frame in the washing machine. A balance ring is provided at the open end of the inner barrel. Compared with the existing method of setting the balance ring on the middle barrel between the inner barrel and the outer barrel, the washing capacity of the inner barrel can be avoided from being reduced. The support frame can play the role of fixing the inner barrel. The structure is small in size and low in cost. It is possible to replace the inner barrel to wash clothes separately to avoid cross infection.

[0034] (4) The present invention forms a plurality of protrusions by arranging the guide portion protruding from the inner side to the outer side of the inner barrel, and forms a plurality of recessed areas on the inner peripheral wall of the inner barrel, so that water flows upward along the first side wall of each recessed area and is discharged from the dehydration hole, thereby accelerating the discharge of water. The present invention can also form a plurality of protrusions on the outer peripheral wall of the inner barrel, and the slide groove is formed between adjacent protrusions, which is installed in conjunction with the support frame to facilitate one-piece injection molding, and the slide groove and the guide portion are formed at the same time, without the need to process the slide groove separately, thereby simplifying the processing and reducing the cost.

[0045] As shown in FIG. 1 to FIG. 3 , the present invention provides a washing tub assembly. The washing tub assembly includes an inner tub 1 and can be used in a pulsator washing machine.

[0046] One end of the inner tub 1 is open, and a balance ring 11 is provided at the open end of the inner tub 1. A dehydration hole 12 is provided on the circumferential wall of the inner tub 1 above the maximum water level. The inner tub 1 is a hole-free inner tub 1, which can be used for washing and dehydration by rotating the inner tub 1 to drive water up the inner circumferential wall of the inner tub 1 to be discharged through the dehydration hole 12. This ensures that the outer surface of the inner tub 1 is not easily wetted for a long time, thus preventing the accumulation of dirt.

[0047] The inner wall of the inner tub 1 is provided with a recessed guide portion 13 extending from the bottom of the inner tub 1 toward the open end. A first sidewall 131 of the guide portion 13 extends obliquely to guide water upward toward the dehydration hole 12 during dehydration.

[0048] The present invention provides a recessed guide portion 13 on the inner circumferential wall of the non-perforated inner tub 1. The guide portion 13 extends obliquely from the bottom of the inner tub 1 toward the first sidewall 131 extending toward the open end. When the inner tub 1 rotates for dehydration, the water in the tub, under the action of centrifugal force, tends to gradually rise within the guide portion 13 along the inclined first sidewall 131 and be discharged from the dehydration hole 12 at the open end of the inner tub 1, greatly improving the dehydration rate. During washing, the protruding sidewall within the guide portion 13 can also improve cleaning performance. Furthermore, the balance ring 11 on the open end of the inner tub 1 can prevent the water flowing up along the first sidewall 131 from overflowing.

[0049] The inner barrel 1 is arranged in a bell-mouthed inclined manner, and the inner diameter gradually increases from the bottom of the barrel to the open end. In conjunction with the recessed guide portion 13 provided on the inner circumferential wall of the inner barrel 1, it is more conducive to the water flow in the inner barrel 1 to flow upward easily during dehydration and be discharged from the dehydration hole 12 more quickly.

[0050] The peripheral wall of the inner barrel 1 is tilted outward by 1°-5° in the vertical direction of the central axis.

[0051] The dehydration hole 12 is a round hole or a square hole, and no additional drainage hole is provided on the peripheral wall of the inner barrel 1 below the dehydration hole 12 .

[0052] As shown in FIG. 1 and FIG. 2 , the guide portion 13 extends from the bottom of the inner tub 1 to the dehydration hole 12 of the inner tub 1 , and the first side wall 131 of the guide portion 13 extends obliquely into the dehydration hole 12 .

[0053] In the present invention, by extending the guide portion 13 from the bottom of the inner tub 1 to the dehydration hole 12 of the inner tub 1, the end of the first side wall 131 directly extends into the dehydration hole 12. During dehydration, the water flow at the bottom of the inner tub 1 can rise directly along the first side wall 131 into the dehydration hole 12, thereby further improving the dehydration efficiency of the inner tub 1.

[0054] The inclination direction of the first side wall 131 of the guide portion 13 is opposite to the dehydration rotation direction of the inner tub 1 .

[0055] When the inner tub 1 rotates for dehydration, the water on the clothes is separated from the clothes under the action of inertia and moves in the direction opposite to the rotation direction of the inner tub 1. It rises along the first side wall 131 in the direction opposite to the rotation direction of the inner tub 1 to the dehydration hole 12 at the open end, cooperating with the rotation direction of the inner tub 1 to accelerate the dehydration rate and guide the water separated from the clothes to be discharged quickly.

[0056] The first side wall 131 may be arranged to extend upwardly and obliquely along a straight line, and the first side wall 131 of the guide portion 13 may be inclined at an angle of 20° to 80° to a horizontal plane.

[0057] The first side wall 131 may also be arranged to extend upward in an arc shape, with the bottom end of the first side wall 131 and the horizontal plane having an included angle of 20°-80°, or the connecting line between the bottom end and the top end of the first side wall 131 and the horizontal plane having an included angle of 20°-80°.

[0058] Preferably, the first side wall 131 of the guide portion 13 is inclined at an angle of 30° to 60° with respect to the horizontal plane. The first side wall 131 is inclined and extends from the bottom of the inner tub 1 in a counterclockwise direction.

[0059] The second side wall 132 on the other side of the guide portion 13 extends vertically from the bottom of the inner tub 1 along the axial direction toward the open end of the inner tub 1. As the guide portion 13 extends toward the open end, the first side wall 131 of the guide portion 13 extends obliquely and gradually away from the second side wall 132 of the guide portion 13.

[0060] The guide portion 13 of the present invention has a narrow bottom and a wide top, and can collect the separated water at the bottom and then drain the separated water upward along the first side wall 131 .

[0061] Furthermore, the inner barrel 1 comprises a barrel bottom wall 17 and a barrel body 16 with two ends open. The barrel bottom wall 17 and the barrel body 16 are integrally injection-molded, and the guide portion 13 is provided on the inner circumferential wall of the barrel body 16.

[0062] The inner barrel 1 is made of plastic and is integrally injection molded. By arranging the guide portion 13 on the inner circumferential wall of the cylinder 16, the strength of the inner barrel 1 can be improved, and it can be easily demoulded during the production of plastic barrels, thereby greatly improving production efficiency and reducing production costs.

[0063] As shown in Figures 2 and 3, the bottom of the balancing ring 11 is fixed to one end opening of the inner tub 1, and the dehydration hole 12 is located near the balancing ring 11. The portion of the bottom wall of the balancing ring 11 that protrudes inward from the opening is a guide plate 111, which extends inward and downward from the inner peripheral wall of the opening to the dehydration hole 12. This guide plate can guide water in the inner tub 1 that reaches the dehydration hole 12 to flow downward into the inner tub 1, preventing water from splashing outside the opening and preventing water overflow.

[0064] The guide plate 111 is annular, and the inner ring end of the guide plate 111 is substantially flush with the dehydration hole 12 or slightly exceeds the dehydration hole 12 downward.

[0065] Part of the bottom wall of the balance ring 11 protrudes outward from the outer peripheral wall of the open end of the inner barrel 1. The balance ring 11 is also provided with a water baffle 112, which extends downward from the outer ring end of the bottom wall of the balance ring 11 and is arranged beyond the dehydration hole 12.

[0066] The present invention provides a water baffle 112 extending downward from the outer ring end of the bottom wall of the balance ring 11. The water baffle 112 extends downward and is arranged to exceed the dehydration hole 12. When the washing machine is a double-barrel washing machine, the inner barrel 1 is arranged in the outer barrel. During washing, there is no water between the inner barrel 1 and the outer barrel. When the inner barrel 1 is dehydrated, after the water is discharged from the dehydration hole 12, the water can be discharged directly downward through the outer barrel, which can prevent the discharged water from hitting the outer barrel and splashing.

[0067] The bottom wall of the balancing ring 11 is further provided with a downwardly opening annular slot 113. The slot 113 can be located at the open end of the inner tub 1 and is used to secure the balancing ring 11 to the inner tub 1. The dewatering hole 12 is located below the open end of the slot 113. The guide plate 111 and the water baffle 112 both extend downward beyond the open end of the slot 113.

[0068] Furthermore, the washing tub assembly further comprises a support frame (not shown in the figure). The support frame has a receiving cavity therein. The other end, i.e., the bottom end, of the inner tub 1 is detachably fixed in the receiving cavity of the support frame and is circumferentially limited with the support frame.

[0069] The present invention adds a support frame, which can be rotatably fixed in the outer barrel of the washing machine, and the bottom end of the inner barrel 1 can be detachably fixed in the support frame, thereby reducing the space occupied by the support frame in the washing machine. The open end of the inner barrel 1 is provided with a balance ring 11. Compared with the existing method of setting the balance ring 11 on the middle barrel between the inner barrel 1 and the outer barrel, the washing capacity of the inner barrel 1 can be avoided. The support frame can fix the inner barrel 1. The structure is small in size and low in cost. It is possible to replace the inner barrel 1 to wash clothes separately to avoid cross infection.

[0070] Preferably, the upper edge of the support frame is lower than the height of the dehydration hole 12 of the inner tub 1. The inner circumference of the support frame's accommodating cavity has protrusions extending to both axial ends. A recessed sliding groove 15 is provided on the outer circumferential wall of the bottom end of the inner tub 1, extending axially and slidably engaging the protrusion within the support frame.

[0071] The slide groove 15 slides from the inlet end of the accommodating cavity and is clamped on the protrusion in the support frame, which not only facilitates the quick disassembly and assembly of the inner barrel 1 and the support frame, but also prevents the inner barrel 1 from rotating circumferentially relative to the support frame, preventing the inner barrel 1 from rotating, shifting, and shaking.

[0072] A rotatable handle is provided on the outer peripheral wall of the open end of the inner tub 1 and is located on the outer periphery of the balance ring 11 , and the inner tub 1 can be lifted out of the washing machine by the handle.

[0073] Furthermore, the height of the support frame is lower than the height of the dehydration hole 12 of the inner tub 1, which can facilitate the dehydration of the inner tub 1 and prevent water from being reflected from the dehydration hole 12 to the support frame and causing splashing.

[0074] Preferably, the height of the support frame 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.

[0075] The specific height may be that the upper end of the support frame 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 .

[0076] Preferably, the upper edge of the support frame 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 can be higher than one-quarter the height of the inner barrel 1 and lower than half the height of the inner barrel 1.

[0077] The support frame may be in a barrel or basket shape.

[0078] Preferably, the support frame includes a base plate, a plurality of connecting arms and annular arms.

[0079] One end of a plurality of connecting arms is circumferentially spaced apart on the outer peripheral edge of the base plate, and the other end extends axially or toward the opening of the inner barrel 1. The annular arm is connected to the other ends of the plurality of connecting arms to form the accommodating cavity. The protrusion is provided on the inner side of the connecting arm. Preferably, the protrusion is formed by protruding from the outside to the inside from the connecting arm and the annular arm at the connection.

[0080] Furthermore, a plurality of dehydration holes 12 are provided on the peripheral wall of the open end of the inner tub 1 at intervals along the circumferential direction, and the inner tub 1 is provided with a plurality of guide portions 13 provided at intervals along the circumferential direction.

[0081] The guide portion 13 protrudes from the inner side of the inner tub 1 to the outer side to form a protrusion 14, which is located between two adjacent connecting arms of the support frame. The recessed portion between adjacent protrusions 14 on the outer side of the inner tub 1 forms the slide groove 15.

[0082] The present invention forms a plurality of protrusions 14 on the outside by protruding the guide portion 13 from the inside to the outside of the inner barrel 1, and forms a plurality of recessed areas on the inner peripheral wall of the inner barrel 1, so that water flows upward along the first side wall 131 of each recessed area and is discharged from the dehydration hole 12, thereby accelerating the discharge of water. The present invention also forms a plurality of protrusions 14 on the outer peripheral wall of the inner barrel 1, and the slide groove 15 is formed between adjacent protrusions 14, which is installed in conjunction with the support frame to facilitate one-piece injection molding, and simultaneously forms the slide groove 15 and the guide portion 13, without the need to separately process the slide groove 15, resulting in simple processing and low cost.

[0083] Preferably, the slide groove 15 extends from the bottom of the inner barrel 1 to the open end with an inner diameter gradually decreasing. When the inner barrel 1 is installed in the support frame, the slide groove 15 at the bottom end of the inner barrel 1 is aligned with the protrusion on the support frame, slides from top to bottom, and the inner diameter gradually decreases to be clamped on the protrusion.

[0084] 2-6 guide portions 13 are provided on the inner circumferential wall of the inner barrel 1 .

[0085] The present invention also provides a pulsator washing machine having any of the above-mentioned washing tub assemblies.

[0086] The washing machine also includes an outer tub, a pulsator 18, and a deceleration clutch. The deceleration clutch is fixed to the outside of the bottom of the outer tub. The pulsator 18 is rotatably mounted within the inner tub 1 via a pulsator shaft. The support frame is rotatably mounted within the outer tub, and the inner tub 1 is removably mounted within the support frame. The support frame and the inner tub 1 are synchronously rotatably mounted within the outer tub via a spin shaft, allowing the inner tub 1 to be replaced to wash different items of clothing separately.

[0087] The dehydration shaft is sleeved around the output shaft of the deceleration clutch and extends from the outside into the outer tub, connecting to the support frame and inner tub 1. The dehydration shaft, where the output shaft of the deceleration clutch extends, has an external spline at its upper end, which mates with the internal spline at the lower end of the impeller shaft. The upper end of the impeller shaft extends into the inner tub 1 and is equipped with an external spline, which mates with the impeller liner.

[0088] The washing machine further includes a drain valve disposed outside the bottom of the outer tub for draining water discharged from the inner tub 1 into the outer tub.

[0089] The washing machine further comprises a housing, the housing comprising an upper control panel seat, the control panel seat being provided with a clothes feeding opening and a rotatable upper cover being provided on the control panel seat for closing or opening the clothes feeding opening.

[0090] The outer barrel is provided with an annular outer barrel cover, the inner diameter of which is larger than the maximum outer diameter of the balance ring 11. The outer barrel cover and the balance ring 11 are located below the control plate seat, and the balance ring 11 is arranged opposite to the clothing loading port.
