During the laundry process, the tub body of the inner tub forms an independent space, and the clothes are in an isolated state during the laundry process, which can ensure the cleanliness of the clothes and the hygiene and safety during the laundry process. However, although the washing tub of this solution is replaceable, a middle tub is additionally provided, the structure is complex, the cost is high, and when the inner tub is dehydrated, the climbing speed of the water flow along the peripheral wall of the inner tub is slow, and the dehydration efficiency is low.

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

[0006] The technical problem to be solved by the present invention is to overcome at least one of the deficiencies of the prior art. The purpose is to provide a washing tub assembly, in which a guiding part is added inside the inner tub, and dehydration holes are arranged at the balance ring near the top of the inner tub. When the inner tub rotates for dehydration, the water in the inner tub is inclined upward and guided to the dehydration holes by the first side wall in the extending direction of the guiding part, realizing rapid dehydration, improving the dehydration efficiency, having a low structural cost, and also being able to increase the washing effect and improve the washing ratio.

[0007] Another object of the present invention is to provide a washing tub assembly, which is provided with a support frame.

[0008] Another object of the present invention is to provide a pulsator washing machine.

[0009] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is: to provide a washing tub assembly, including:

[0010] An inner tub, with a balance ring provided at the open end, and dehydration holes provided on the peripheral wall of the inner tub above the highest water level;

When the inner tub rotates for dehydration, the water flow in the tub is easily gradually raised along the inclined first side wall in the guiding portion under the action of centrifugal force and discharged from the dehydration holes at the open end of the inner tub, greatly improving the dehydration rate. The protruding side wall in the guiding portion during washing can also improve the washing performance. And the balance ring on the open end of the inner tub can play a role in blocking the overflow of the water flow rising along the first side wall.

[0013] Further, the guiding portion extends from the bottom of the inner tub to the dehydration holes of the inner tub, and the first side wall of the guiding portion is inclined and extends into the dehydration holes.

[0014] Further, the inclination direction of the first side wall of the guiding portion is opposite to the dehydration rotation direction of the inner tub;

[0015] Preferably, the inclination angle between the first side wall of the guiding portion and the horizontal plane is 20° - 80°.

[0016] Further, the second side wall on the other side of the extending direction of the guiding portion extends from the bottom of the inner tub along the axis vertically towards the open end of the inner tub;

[0017] During the process of the guiding portion extending towards the open end, the first side wall of the guiding portion is inclined and extends gradually away from the second side wall of the guiding portion.

[0018] Further, the inner tub includes a bottom wall of the tub and a cylindrical body with openings at both ends. The bottom wall of the tub is integrally injection-molded with the cylindrical body, and the guiding portion is provided on the inner peripheral wall of the cylindrical body.

[0019] Further, the bottom of the balance ring is fixed on one of the openings of the inner tub, and the dehydration holes are arranged close to the balance ring.

[0020] The part of the bottom wall of the balance ring that protrudes inward from the bottom wall of the opening is a flow guide plate, which extends obliquely downward from the inner peripheral wall of the opening to the dehydration holes.

[0021] Further, a part of the bottom wall of the balance ring protrudes outward from the outer peripheral wall of the open end of the inner tub.

[0022] The balance ring is also provided with a water baffle, which extends downward from the outer ring end of the bottom wall of the balance ring and exceeds the dehydration holes.

[0023] Further, it further includes: a support frame having a receiving cavity, and the other end of the inner tub is detachably fixed in the receiving cavity of the support frame and is circumferentially limited with the support frame.

[0024] Preferably, the upper edge of the support frame is lower than the height of the dehydration holes of the inner tub. The inner peripheral side of the receiving cavity of the support frame has protrusions extending to both axial ends, and the outer peripheral wall of the bottom end of the inner tub is provided with a concave chute, which is slidably clamped on the protrusions inside the support frame.

[0025] Further, a plurality of dehydration holes are arranged at intervals along the circumferential direction on the circumferential wall of the open end of the inner tub, and the inner tub is provided with a plurality of guiding portions arranged at intervals along the circumferential direction.

[0026] The guiding portion protrudes from the inner side to the outer side of the inner tub to form a protruding portion on the outer side, and the concave portion between adjacent protruding portions on the outer side of the inner tub forms the chute.

[0027] Preferably, the inner diameter of the chute gradually decreases from the bottom of the inner tub to the open end, and it is slidably clamped on the protrusions from top to bottom.

[0028] The present invention also provides a pulsator washing machine having the washing tub assembly described in any one of the above.

[0029] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art.

[0030] (1) The invention provides a depression guiding portion on the inner peripheral wall of the non-porous inner barrel. The guiding portion extends obliquely from the bottom of the inner barrel towards the opening end. When the inner barrel rotates for dehydration, the water flow in the barrel is easily lifted gradually along the inclined first side wall in the guiding portion under the action of centrifugal force and discharged from the dehydration holes at the opening end of the inner barrel, greatly improving the dehydration rate. During washing, the protruding side wall in the guiding portion can also improve the washing performance. Moreover, the balance ring on the opening end of the inner barrel can prevent the water flowing along the first side wall from overflowing.

[0031] (2) The invention provides a water retaining plate extending downward from the outer ring end of the bottom wall of the balance ring. The water retaining plate extends downward beyond the dehydration holes. When the washing machine is a double-barrel washing machine, the inner barrel is arranged in the outer barrel. During washing, there is no water between the inner barrel and the outer barrel. When the inner barrel is dehydrated, after the water is discharged from the dehydration holes, the water can directly pass downward through the outer barrel, preventing the discharged water from hitting the outer barrel and splashing water.

[0032] (3) The invention provides a support frame. The support frame 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, reducing the space occupied by the support frame in the washing machine. The opening end of the inner barrel is provided with a balance ring. Compared with the existing structure of arranging the balance ring on the middle barrel between the inner barrel and the outer barrel, it can avoid reducing the washing capacity of the inner barrel. The support frame can play a role in fixing the inner barrel, with a small structural volume and low cost, and can realize separating the inner barrel for washing clothes to avoid cross-infection.

[0033] (4) The invention provides a guiding portion protruding from the inner side to the outer side of the inner barrel to form a plurality of protruding portions on the outer side, and a plurality of concave regions are formed on the inner peripheral wall of the inner barrel, facilitating the water flow to rise along the first side wall of each concave region and be discharged from the dehydration holes, accelerating the water flow discharge. Also, a plurality of protruding portions can be formed on the outer peripheral wall of the inner barrel, and a chute is formed between adjacent protruding portions. When assembled with the support frame, it is convenient for integral injection molding, and at the same time, the chute and the guiding portion are formed, eliminating the need for separate machining of the chute, with simple processing and low cost.

[0043] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] As Figures 1 to 3 shown, the present invention provides a washing tub assembly, and the washing tub assembly includes an inner tub 1 and can be used for a pulsator washing machine.

[0045] 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. The peripheral wall of the inner tub 1 above the highest water level is provided with dehydration holes 12. The inner tub 1 is a non-porous inner tub 1, which can realize water-containing washing and drive the water flow to rise along the inner peripheral wall of the inner tub 1 to the dehydration holes 12 during the dehydration of the washing machine, so that the outside of the inner tub 1 is not easily wetted for a long time, avoiding the deposition of dirt.

[0046] A guiding part 13 with a sunken setting is provided on the inner peripheral wall of the inner tub 1, and the guiding part 13 extends from the bottom of the inner tub 1 towards the open end. The first side wall 131 on one side of the extending direction of the guiding part 13 extends obliquely, and is used for guiding the water flow to rise towards the dehydration holes 12 during dehydration.

[0047] In the present invention, by providing a sunken guiding part 13 on the inner peripheral wall of the non-porous inner tub 1, and the first side wall 131 of the guiding part 13 extending obliquely from the bottom of the inner tub 1 towards the open end, when the inner tub 1 rotates during dehydration, the water flow in the tub is easily gradually lifted along the inclined first side wall 131 in the guiding part 13 under the action of centrifugal force, and discharged from the dehydration holes 12 at the open end of the inner tub 1, greatly improving the dehydration rate. The protruding side wall in the guiding part 13 during washing can also improve the washing performance. And the balance ring 11 on the open end of the inner tub 1 can play a role in blocking the overflow of the water flow rising along the first side wall 131.

[0048] The inner tub 1 is arranged in a flared and inclined manner, and the inner diameter gradually increases from the bottom of the tub towards the open end. Cooperating with the sunken guiding part 13 provided on the inner peripheral wall of the inner tub 1, it is more conducive to the water flow in the inner tub 1 being easily lifted upwards and discharged from the dehydration holes 12 more quickly during dehydration.

[0049] The peripheral wall of the inner tub 1 is inclined 1° - 5° outward in the vertical direction of the central axis.

[0050] The dehydration holes 12 are round holes or square holes, etc., and no additional drainage holes are provided on the peripheral wall of the inner tub 1 below the dehydration holes 12.

[0051] As Figures 1 to 2 shown, the guiding part 13 extends from the bottom of the inner tub 1 to the dehydration holes 12 of the inner tub 1, and the first side wall 131 of the guiding part 13 extends obliquely into the dehydration holes 12.

[0052] In the present invention, by extending the guiding part 13 from the bottom of the inner tub 1 to the dehydration holes 12 of the inner tub 1, and the end of the first side wall 131 directly extends into the dehydration holes 12, during dehydration, the water flow at the bottom of the inner tub 1 can directly rise along the first side wall 131 to the dehydration holes 12, further improving the dehydration efficiency of the inner tub 1.

[0053] The inclination direction of the first side wall 131 of the guiding part 13 is opposite to the dehydration rotation direction of the inner tub 1.

[0054] When the inner tub 1 rotates for dehydration, the moisture on the clothes detaches under the action of inertia and moves in the direction opposite to the rotation direction of the inner tub 1. Along the first side wall 131 opposite to the rotation direction of the inner tub 1, it rises along the first side wall 131 to the dehydration holes 12 at the open end, cooperating with the rotation direction of the inner tub 1 to accelerate the dehydration rate and guide the water detached from the clothes to be quickly discharged.

[0055] The first side wall 131 may be inclined and extend upward along a straight line. The inclination angle between the first side wall 131 of the guiding part 13 and the horizontal plane is 20° - 80°.

[0056] The first side wall 131 may also be inclined and extend upward in an arc shape. The inclination angle between the bottom end of the first side wall 131 and the horizontal plane is 20° - 80°, or the inclination angle between the connecting line of the bottom end and the top end of the first side wall 131 and the horizontal plane is 20° - 80°.

[0057] Preferably, the inclination angle between the first side wall 131 of the guiding part 13 and the horizontal plane is 30° - 60°. The first side wall 131 extends obliquely along the counterclockwise direction from the bottom of the inner tub 1.

[0058] The second side wall 132 on the other side of the extending direction of the guiding part 13 extends vertically from the bottom of the inner tub 1 along the axis towards the open end of the inner tub 1. During the process of the guiding part 13 extending towards the open end, the first side wall 131 of the guiding part 13 extends obliquely and gradually moves away from the second side wall 132 of the guiding part 13.

[0059] The bottom of the guiding part 13 of the present invention is narrow and the upper end is wide, which can collect the detached water at the bottom and then discharge the detached water by rising along the first side wall 131.

[0060] Furthermore, the inner tub 1 includes a connected bottom wall 17 and a cylindrical body 16 with openings at both ends. The bottom wall 17 and the cylindrical body 16 are integrally injection - molded, and the guiding part 13 is arranged on the inner peripheral wall of the cylindrical body 16.

[0061] The inner tub 1 is made of plastic and is integrally injection - molded. By arranging the guiding part 13 on the inner peripheral wall of the cylindrical body 16, the strength of the inner tub 1 can be improved, and it is very convenient to demold during the production of the plastic tub, greatly improving the production efficiency and reducing the production cost.

[0062] Such as Figures 2 to 3As shown, the bottom of the balance ring 11 is fixed to the opening at one end of the inner tub 1, and the dehydration holes 12 are arranged close to the balance ring 11. The part of the bottom wall of the balance ring 11 that protrudes inward from the opening is a guide plate 111, which extends obliquely downward from the inner peripheral wall of the opening to the dehydration holes 12, and can guide the water flow reaching the dehydration holes 12 in the inner tub 1 to flow downward into the inner tub 1, avoiding water splashing outside the opening end and preventing water overflow.

[0063] The guide plate 111 is annular, and the inner ring end of the guide plate 111 is basically flush with the dehydration holes 12 or slightly extends downward beyond the dehydration holes 12.

[0064] Part of the bottom wall of the balance ring 11 protrudes outward from the outer peripheral wall of the opening end of the inner tub 1. The balance ring 11 is further provided with a water baffle 112, which extends downward from the outer ring end of the bottom wall of the balance ring 11 and extends beyond the dehydration holes 12.

[0065] In the present invention, the water baffle 112 extending downward from the outer ring end of the bottom wall of the balance ring 11 extends downward beyond the dehydration holes 12. When the washing machine is a double-barrel washing machine, the inner tub 1 is arranged in the outer tub, and there is no water between the inner tub 1 and the outer tub during washing. When the inner tub 1 is dehydrated, after the water is discharged from the dehydration holes 12, the water can directly pass downward through the outer tub, preventing the discharged water from hitting the outer tub and splashing water.

[0066] The bottom wall of the balance ring 11 is further provided with an annular card slot 113 with an opening facing downward. The card slot 113 can be on the opening end of the inner tub 1 for fixing the balance ring 11 on the inner tub 1. The dehydration holes 12 are located below the opening end of the card slot 113, and both the guide plate 111 and the water baffle 112 extend downward beyond the opening end of the card slot 113.

[0067] Further, the washing tub assembly further includes a support frame (not shown in the figure). The support frame has a receiving cavity. The other end of the inner tub 1, that is, the bottom end, is detachably fixed in the receiving cavity of the support frame and is circumferentially limited with the support frame.

[0068] By adding a support frame in the present invention, the support frame can be rotatably fixed in the outer tub of the washing machine, the bottom end of the inner tub 1 can be detachably fixed in the support frame, reducing the space occupied by the support frame in the washing machine. The opening end of the inner tub 1 is provided with a balance ring 11. Compared with the existing structure of setting the balance ring 11 on the middle tub between the inner tub 1 and the outer tub, it can avoid reducing the washing capacity of the inner tub 1. The support frame can play a role in fixing the inner tub 1, with a small structural volume and low cost, and can realize separating the inner tub 1 to wash clothes separately, avoiding cross-infection.

[0069] Preferably, the upper edge of the support frame is lower than the height of the dehydration hole 12 of the inner barrel 1. The inner peripheral side of the accommodating cavity of the support frame has a protrusion extending to both ends of the axial direction. A concave sliding groove 15 is provided on the outer peripheral wall of the bottom end of the inner barrel 1, extending along the axial direction and slidably engaged with the protrusion in the support frame.

[0070] 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, and prevents the inner barrel 1 from rotating, shifting, and shaking.

[0071] 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.

[0072] 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 the water separated from the dehydration hole 12 from reflecting to the support frame and causing splashing.

[0073] 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 peripheral direction, and also have sufficient strength in the axial direction.

[0074] 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 .

[0075] Preferably, the upper edge of the support frame may be higher than one-half the height of the inner barrel 1 and lower than three-quarters the height of the inner barrel 1, or the upper edge of the support frame may be higher than one-quarter the height of the inner barrel 1 and lower than one-half the height of the inner barrel 1.

[0076] The support frame may be in a barrel or basket shape.

[0077] Preferably, the support frame includes a base plate, a plurality of connecting arms and annular arms.

[0078] One end of a plurality of connecting arms is arranged at intervals along the circumferential direction on the outer peripheral edge of the bottom plate, and the other end is extended along the axial direction, or extended toward the opening side 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 arranged on the inner side of the connecting arm. Preferably, the protrusion is formed by protruding from the connecting arm and the annular arm at the connection point from the outside to the inside.

[0079] 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.

[0080] The guide portion 13 protrudes from the inner side of the inner barrel 1 to the outer side to form a protrusion 14, which is located between two adjacent connecting arms of the support frame. The concave portion between adjacent protrusions 14 on the outer side of the inner barrel 1 forms the slide groove 15.

[0081] The present invention forms a plurality of protrusions 14 on the outer side by protruding the guide portion 13 from the inner side to the outer side 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 can flow up along the first side wall 131 of each recessed area and be discharged from the dehydration hole 12, thereby accelerating the discharge of water. A plurality of protrusions 14 can also be formed 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 coordination with the support frame to facilitate integrated injection molding, and the slide groove 15 and the guide portion 13 are formed at the same time, without the need to process the slide groove 15 separately, so the processing is simple and the cost is low.

[0082] 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 with an inner diameter gradually decreasing, and is clamped on the protrusion.

[0083] 2-6 guide parts 13 are provided on the inner peripheral wall of the inner barrel 1 .

[0084] The present invention also provides a pulsator washing machine having any of the above-mentioned washing tub assemblies.

[0085] The washing machine also includes an outer barrel, a pulsator 18 and a deceleration clutch. The deceleration clutch is fixed to the outside of the bottom of the outer barrel. The pulsator 18 is rotatably arranged inside the inner barrel 1 through the pulsator shaft. The support frame is rotatably fixed in the outer barrel, and the inner barrel 1 is detachably arranged in the support frame. The support frame and the inner barrel 1 are synchronously rotatably arranged in the outer barrel through the dehydration shaft, so that the inner barrel 1 can be replaced to wash different clothes separately.

[0086] The dehydration shaft sleeve is arranged outside the output shaft of the deceleration clutch, passes through the outer barrel from the outside, and is connected to the support frame and the inner barrel 1. The output shaft of the deceleration clutch passes through the upper end of the dehydration shaft and is provided with an external spline, which is matched and installed with the internal spline provided at the lower end of the impeller shaft. The upper end of the impeller shaft passes through the inner barrel 1, and is provided with an external spline, which is matched and installed with the impeller liner.

[0087] The washing machine further comprises a drain valve, which is arranged outside the bottom of the outer tub and is used to drain the water separated from the inner tub 1 and discharged into the outer tub.

[0088] The washing machine further includes a cabinet, which includes a control panel base at the upper part, and a laundry inlet is provided on the control panel base. A rotatable upper cover is provided on the control panel base for closing or opening the laundry inlet.
