Description

TECHNICAL FIELD

[0001] The present application belongs to the field of washing machines, in particular to an automatic balance washing machine. BACKGROUND

[0002] Washing machine is a common household appliance in life, which has the functions of washing and dewatering, but because the washing objects gather together after the washing is finished instead of being evenly laid in the washing barrel, the weight distribution in the barrel is uneven during the dewatering process, which leads to that the dewatering speed cannot reach the normal speed and resonance with the washing machine to produce noise.

[0003] At present, the washing machine sends a command to the washing dewatering barrel before entering the dewatering step, and the washing barrel rotates back and forth repeatedly to let the washing objects spread as evenly as possible in the washing barrel to avoid the effect of producing noise due to severe vibration during dewatering. The disadvantage of the above method is that according to the different materials of the washing objects, the washing barrel may not be able to lay the washing objects evenly sometimes, but instead let the washing objects further gather during the adjustment process, which is more likely to cause noise due to eccentric operation.

[0004] Or install a hollow balance ring on the inner barrel of the washing machine, fill liquid and / or other filling materials in the balance ring, and the filling materials can move in the balance ring. When the washing machine operates eccentrically, the filling materials in the balance ring automatically slide to a position symmetrical to the eccentric load of the washing machine, reducing the overall eccentricity and reducing vibration noise. The disadvantage of the above method is that the eccentricity of the washing machine varies each time it works, and a fixed amount of filling materials often leads to that the eccentricity cannot be completely offset, greatly affecting the correction effect of the eccentricity.

[0005] In view of the above problems, the Chinese invention patent with publication number CN104120584A discloses a washing machine with active injection balance ring and its control method. The position of the washing dewatering barrel eccentricity is determined by eccentricity detection, and then water is added to the balance ring of the washing machine through the water inlet end of the washing machine to accurately correct the eccentricity of the dewatering barrel. The disadvantage of the above technical solution is that the balance device is complex, and water needs to be added to the balance ring from the water inlet end, which is easy to cause waste of water resources.

[0006] The Chinese invention patent with publication number CN109898272A discloses a washing machine inner drum automatic balance device and balance method. A plurality of balance cavities are installed on the inner wall of the washing machine drum at equal angles, and the position that needs to be balanced and compensated and the amount of balance liquid needed are determined after detecting the dynamic balance state of the inner barrel. Balance liquid is gradually injected into the balance cavity that needs to be injected, so as to solve the problem of eccentric operation of the washing machine. Although the above technical solution has been improved on the basis of the existing technology, it still does not solve the problems of complex balance device and easy waste of water resources.

[0007] In view of the above prior art problems, the present application is proposed. SUMMARY

[0008] The present application aims at solving the above problems of the prior art, and provides an automatic balancing washing machine, which is provided with automatic balancing devices on the inner barrel wall of the washing machine to collect the water splashed out during the dehydration process and guide the water to the position where the deviation needs to be corrected, so as to automatically correct the deviation of the washing machine.

[0009] To solve the above problems, the present application provides an automatic balancing washing machine, which comprises an inner barrel and at least one set of automatic balancing devices installed on the inner barrel, wherein the automatic balancing device comprises a collector for collecting the water splashed out during the dehydration process, a water box for storing the water splashed out, and a water guide pipe connecting the collector and the water box, and the collector and the water box are arranged on the barrel wall on the two sides symmetrical to the center of the inner barrel.

[0010] The present application can solve the problem of deviation of the inner barrel due to uneven distribution of the washing materials during the dehydration process of the washing machine, and at least two sets of automatic balancing devices are installed on the inner barrel wall at equal intervals to automatically correct the deviation of the washing machine during the dehydration process.

[0011] Further, the water box and the collector of the automatic balancing device are different in axial distance from the bottom of the inner barrel; alternatively, the axial distance of the collector from the bottom of the inner barrel is greater than that of the water box from the bottom of the inner barrel, or the axial distance of the collector from the bottom of the inner barrel is less than that of the water box from the bottom of the inner barrel.

[0012] Preferably, the axial distance of the collector from the bottom of the inner barrel is greater than that of the water box from the bottom of the inner barrel.

[0013] The above preferred scheme has the beneficial effect that the splashed water can enter the water box under the synergistic action of gravity and centrifugal force to correct the deviation.

[0014] Alternatively, the water box and the collector of the automatic balancing device are the same in axial distance from the bottom of the inner barrel.

[0015] Further, the extension direction of the water guide pipe from the collector to the water box is opposite to the rotation direction of the inner barrel during the dehydration process.

[0016] Further, the radial distance from the connection between the water guide pipe and the collector to the barrel wall of the inner barrel is less than or equal to the radial distance from the connection between the water guide pipe and the water box to the barrel wall of the inner barrel, and this installation method has the beneficial effect that the splashed water can be transferred from the collector to the water box under smaller centrifugal force, thereby solving the problem that the water cannot be transferred along the water guide pipe under the insufficient centrifugal force in the low-speed operation state, and expanding the application range of the device so that the device can be used in a drum washing machine.

[0017] Further, the collector is provided with a first connecting port on the side opposite to the direction of the rotation of the inner drum.

[0018] Further, the water box is provided with a second connecting port on the side facing the direction of the rotation of the inner drum, and the water guide pipe communicates with the water box through the second connecting port.

[0019] Further, the automatic balancing device is provided with a drain port, which is arranged at the lowest position of the automatic balancing device and is used to drain the washing water in the automatic balancing device when the dehydration is completed.

[0020] Further, the drain port can be arranged on the collector and / or the water box, when the axial distance between the collector and the bottom of the inner drum is greater than the axial distance between the water box and the bottom of the inner drum, the drain port is arranged only on the water box; when the axial distance between the collector and the bottom of the inner drum is less than the axial distance between the water box and the bottom of the inner drum, the drain port is arranged only on the collector; when the axial distance between the collector and the bottom of the inner drum is the same as the axial distance between the water box and the bottom of the inner drum, the drain port is arranged on both the collector and the water box.

[0021] Further, the inner drum is provided with a drain pipe, and the drain port communicates with the drain pipe.

[0022] The above technical scheme collects the water thrown out in different directions around the inner drum, and the water is drained from the collector under the action of gravity and / or centrifugal force, and then flows into the water box through the water guide pipe, so that the water thrown out on one side is transferred and stored on the other side opposite to the one side, and the purpose of automatically correcting the eccentricity of the washing machine during the dehydration process is achieved.

[0023] The above technical scheme realizes the correction of the eccentricity in multiple directions by installing at least two groups of automatic balancing devices on the inner drum wall at equal intervals, which can replace or assist the balance ring arranged on the inner drum, and can correct the eccentricity in the low-speed and high-speed operation states of the inner drum; meanwhile, the automatic balancing device overcomes the defects of the eccentric ring, and the water thrown out in the automatic balancing device is drained from the drain port when the inner drum stops rotating, so that the residual water in the automatic balancing device is avoided to increase the operation load of the washing machine; further, the automatic balancing device avoids the influence of the residual water on the operation balance of the washing machine, and also avoids the influence of the residual water in the collector on the dehydration effect of the washing materials.

[0024] Another aspect of the present application can solve the eccentricity caused by the structural design of the washing machine, and a group of automatic balancing devices are installed on the inner drum wall according to the direction of the structural eccentricity, so that the automatic correction of the structural eccentricity of the washing machine is realized.

[0025] The structure of the automatic balancing device is as described in the previous technical solutions, the collector is arranged on the inner drum outer wall of the eccentric side of the inner drum structure, the water box is arranged on the inner drum wall of the other side opposite to the eccentric side of the inner drum structure, and the water thrown out from the eccentric side is transferred to the water box on the other side opposite to the eccentric side through the water guide pipe, so that the eccentricity of the washing machine structure is corrected.

[0026] The above technical solution corrects the eccentricity caused by the design of the washing machine structure by arranging a set of automatic balancing devices on the inner drum wall, which overcomes the design defects of the eccentric ring and can replace or assist the balance ring arranged on the inner drum, avoids the influence of residual water on the balance of the washing machine, and at the same time, the automatic balancing device avoids the residual water in the collector affecting the dehydration effect of the washing material.

[0027] In summary of the above technical solutions, the automatic balancing device has the advantages of simple structure, low production cost, and can replace or assist the balance ring arranged on the inner drum, and is effective in the low-speed and high-speed running stages, can effectively reduce the eccentricity in the dehydration stage, reduces the running noise of the washing machine, and improves the user experience.

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

[0041] This invention provides an automatic balancing washing machine, wherein the automatic balancing device is installed on the inner tub 7 as follows: Figure 1 As shown, the automatic balancing device includes: a collector 1, a water guide pipe 2, and a water box 3. The collector 1 and the water box 3 are arranged on the two sides of the inner tub 7 symmetrically opposite to the center of the inner tub 7. A first connection port 6 is provided on the collector 1, and a second connection port 4 is provided on the water box 3. The first connection port 6 on the collector 1 and the second connection port 4 on the water box 3 are connected by the water guide pipe 2, and the direction of extension of the water guide pipe 2 from the collector 1 to the water box 3 is opposite to the direction of rotation of the inner tub 7 during dehydration. The arc arrow in the figure represents the direction of rotation of the inner tub 7 during dehydration.

[0042] As an embodiment of the present application, the embodiment provides an automatic balance washing machine, only a set of automatic balance devices is installed on the inner barrel wall of the washing machine, which is used to correct the eccentricity caused by the structural design of the pulsator washing machine, the collector 1 in the automatic balance device is arranged on the outer wall of the inner barrel on the side of the eccentricity of the washing machine structure, and the water box 3 is arranged on the outer wall of the inner barrel on the side opposite to the side of the eccentricity of the washing machine structure.

[0043] Preferably, the radial distance from the first connecting port 6 on the collector 1 to the inner barrel wall is less than or equal to the radial distance from the second connecting port 4 on the water box 3 to the inner barrel wall.

[0044] The relative positions of the collector 1 and the water box 3 in the embodiment are as shown in Figure 2 The axial distance from the collector 1 to the bottom of the inner barrel is greater than the axial distance from the water box 3 to the bottom of the inner barrel.

[0045] Further, the structures of the water box 3 and the collector 1 are as shown in Figure 4 and Figure 8 The side of the collector 1 opposite to the direction of the dehydration rotation of the inner barrel 7 is provided with the first connecting port 6, and the side of the water box 3 same as the direction of the dehydration rotation of the inner barrel 7 is provided with the second connecting port 4.

[0046] As a supplement to the above technical solution, the first connecting port 6 is arranged close to the lowest part of the collector 1, the second connecting port 4 is arranged close to the highest part of the water box 3, and the two ends of the water guide pipe 2 are respectively communicated with the first connecting port 6 and the second connecting port 4.

[0047] The purpose of the above-mentioned supplementary technical solution is to avoid that a large amount of the thrown-out water is left in the automatic balance device.

[0048] Preferably, the water guide pipe 2 is fixedly installed on the inner barrel wall.

[0049] In order to prevent the thrown-out water in the water box 3 from being unable to be discharged, affecting the effect of the automatic balance device, the water box 3 is further provided with a drain port 5, which is arranged at the lowest part of the water box 3.

[0050] After the dehydration step is started, the collector 1 collects the thrown-out water on the side of the eccentricity of the washing machine structure, the thrown-out water flows out from the first connecting port 6 on the collector 1 under the action of gravity and centrifugal force, passes through the water guide pipe 2 and flows into the water box 3 on the side opposite to the side of the eccentricity of the washing machine structure through the second connecting port 4, at this time, the thrown-out water is gathered in the water box 3 far away from the second connecting port 4 under the action of the centrifugal force and cannot flow out from the drain port 5, thereby achieving the purpose of transferring the water on the side of the eccentricity to the water box 3 on the side opposite to the side of the eccentricity to correct the eccentricity.

[0051] At the end of the dehydration, the inner barrel 7 rotation speed is reduced, the water in the water box 3 is discharged from the drainage port 5 under the action of inertia, and the residual water in the water box 3 is avoided, and the operation load is reduced.

[0052] As a further preferred embodiment of the present application, a drainage pipe is further arranged on the inner barrel wall, the drainage port 5 and the drainage pipe are communicated, and the water in the water box 3 is discharged from the water box 3.

[0053] The use of the drainage pipe to discharge the water can avoid the water flowing along the barrel wall into the inner barrel during the drainage of the water in the water box 3, and the dehydration effect of the washing object is affected.

[0054] Preferably, the collector 1 and the water box 3 are arranged at positions provided with clamping grooves corresponding to the clamping claws 9, and the collector 1 and the water box 3 in the automatic balancing device are connected to the inner barrel wall through the clamping claws 9 arranged thereon.

[0055] The above-mentioned preferred embodiment realizes the fixation of the automatic balancing device through a small amount of modification of the inner barrel 7, and the fixation mode can more conveniently complete the replacement of each component in the automatic balancing device.

[0056] As another embodiment of the present application, the present embodiment provides an automatic balancing washing machine, which is provided with a set of automatic balancing devices on the inner barrel wall, used for correcting the eccentricity generated in the structural design of the drum washing machine, and the collector 1 in the automatic balancing device is arranged on the outer wall of the inner barrel on the side of the eccentricity of the washing machine structure, and the water box 3 is arranged on the outer wall of the inner barrel on the side opposite to the eccentricity of the washing machine structure.

[0057] Preferably, the radial distance from the first connecting port 6 on the collector 1 to the inner barrel wall is less than or equal to the radial distance from the second connecting port 4 on the water box 3 to the inner barrel wall.

[0058] The above-mentioned preferred technical solution aims to ensure that the water can smoothly enter the water box 3 under the action of centrifugal force, avoid the uniform distribution of the water in the automatic balancing device away from the inner barrel wall, and the water cannot smoothly enter the water box 3, thereby causing the failure of the automatic balancing device, and also avoid the water swinging in the automatic balancing device to affect the balancing effect.

[0059] Further, the first connecting port 6 is arranged on the side of the collector 1 opposite to the dehydration rotation direction of the inner barrel 7, and the second connecting port 4 is arranged on the side of the water box 3 same as the dehydration rotation direction of the inner barrel 7.

[0060] Further, in order to prevent the water in the water box 3 from being unable to be discharged, affecting the effect of the automatic balancing device, the first connecting port 6 is arranged close to the lowest part of the collector 1, and the second connecting port 4 is arranged close to the lowest part of the water box 3.

[0061] The first connecting port 6 and the second connecting port 4 are communicated through the water guide pipe 2.

[0062] Preferably, the water guide pipe 2 is fixedly installed on the inner tub wall.

[0063] Meanwhile, in order to completely drain the collector 1 and the water box 3 after the dehydration, a drain port 5 is further arranged on the collector 1 and the water box 3.

[0064] Preferably, the drain port 5 is arranged at the lowest position of the collector 1 and the water box 3.

[0065] During the dehydration process, the spun-out water on the eccentric side of the washing machine structure is collected by the collector 1 and transferred to the water box 3 on the side opposite to the eccentric side under the action of the centrifugal force through the water guide pipe 2, at this time, the spun-out water is gathered in the water box 3 far away from the second connecting port 4 under the action of the centrifugal force and cannot flow out of the drain port 5, which guarantees the automatic balancing effect and realizes the purpose of transferring the water on the eccentric side to the water box 3 on the side opposite to the eccentric side to correct the eccentricity.

[0066] At the end of the dehydration, the rotation speed of the inner tub 7 is reduced, part of the spun-out water in the water box 3 approaches the drain port 5 under the action of the inertia and is drained from the drain port 5, which avoids the residual spun-out water in the water box 3 and reduces the operation load, and the other part of the spun-out water returns to the collector 1 along the water guide pipe 2 and is drained from the drain port 5 on the collector 1 along the drain pipeline, which avoids the return of the spun-out water to the inner tub and affects the dehydration effect of the washing material.

[0067] As a preferred embodiment of the present embodiment, a drain pipeline is further arranged on the inner tub wall and communicated with the drain port 5.

[0068] The drain pipeline is used for draining water, which further avoids the return of the spun-out water to the inner tub and affects the dehydration effect of the washing material.

[0069] As another embodiment of the present application, the present embodiment provides an automatic balancing washing machine, three groups of automatic balancing devices are arranged on the inner tub wall of the washing machine at equal intervals, which are used for correcting the eccentricity caused by the uneven distribution of the washing material during the dehydration process of the pulsator washing machine.

[0070] In the present embodiment, the radial distance from the first connecting port 6 on the collector 1 to the inner tub wall is less than or equal to the radial distance from the second connecting port 4 on the water box 3 to the inner tub wall.

[0071] The above scheme aims to make the spun-out water flow in the automatic balancing device under the action of the smaller centrifugal force, which guarantees the normal operation of the automatic balancing device under the low speed state.

[0072] Further, the relative position of the collector 1 and the water box 3 is as shown in the following table: Figure 2As shown, the axial distance between the collector 1 and the inner tub bottom is greater than the axial distance between the water box 3 and the inner tub bottom.

[0073] Further preferably, the water box 3 and the collector 1 are structured as shown in Figure 4 and Figure 8 As shown, the collector 1 is provided with a first connecting port 6 on the side opposite to the direction of dehydration rotation of the inner tub 7, and the water box 3 is provided with a second connecting port 4 on the side same as the direction of dehydration rotation of the inner tub 7.

[0074] Preferably, the first connecting port 6 is arranged close to the lowest part of the collector 1, and the second connecting port 4 is arranged close to the highest part of the water box 3.

[0075] The above preferred embodiment can avoid a large amount of splashing water remaining in the automatic balancing device, and avoid affecting the dehydration effect on the washing objects.

[0076] Further, the first connecting port 6 and the second connecting port 4 are connected through a water guide pipe 2.

[0077] Preferably, the water guide pipe 2 is fixedly installed on the inner tub wall.

[0078] Further, the water box 3 is further provided with a drain port 5 arranged at the lowest part of the water box 3.

[0079] The above technical solution can avoid splashing water remaining in the water box 3 after dehydration, and avoid increasing the running load of the washing machine.

[0080] After starting the dehydration step, the uneven distribution of the load in the tub causes the inner tub to produce eccentricity during rotation. At this time, the amount of splashing water in each direction of the inner tub is different, and the amount of splashing water in the eccentric direction is relatively more than that in other directions. Three collectors 1 arranged at equal intervals on the inner tub wall collect splashing water in different directions. The splashing water flows out of the first connecting port 6 on the collector 1 under the action of gravity and centrifugal force, flows through the water guide pipe 2 and enters the water box 3 corresponding to each collector 1 through the second connecting port 4. The more splashing water splashed in the eccentric direction is transferred to the water box 3 in the opposite direction of the eccentricity, and the less splashing water splashed in the opposite direction of the eccentricity is transferred to the water box 3 in the direction of the eccentricity, thereby correcting the eccentricity.

[0081] At this time, the water in the water box 3 is gathered at a position away from the second connecting port 4 and the drain port 5 under the action of centrifugal force, so that the splashing water cannot flow out of the drain port 5, thereby ensuring the stability of the automatic balancing effect.

[0082] After the dehydration ends, the dehydration bucket starts to decelerate, at this time the thrown-out water in the water box 3 is close to the second connecting port 4 and the drainage port 5 under the action of inertia, since the second connecting port 4 is arranged close to the highest position of the water box 3, the thrown-out water cannot flow out through the second connecting port 4, and can only flow out of the water box 3 from the drainage port 5, thereby avoiding the thrown-out water remaining in the water box 3 to increase the running load of the washing machine.

[0083] As a further preferred embodiment of the above technical solution, the mounting position of the collector 1 and / or the water box 3 on the inner bucket 7 is provided with a corresponding groove, and the collector 1 and / or the water box 3 is arranged in the groove.

[0084] The above technical solution installs the automatic balancing device between the inner bucket 7 and the outer bucket 8, keeps the distance between the inner bucket 7 and the outer bucket 8 unchanged, or further reduces the distance between the inner bucket 7 and the outer bucket 8, thereby avoiding that the automatic balancing device limits the capacity of the inner bucket, and avoiding that the distance between the inner bucket 7 and the outer bucket 8 is too large to cause waste of water resources during the operation of the washing machine.

[0085] As another embodiment of the present application, the present embodiment provides an automatic balancing washing machine, four groups of automatic balancing devices are arranged on the inner bucket wall of the washing machine at equal intervals, for correcting the eccentricity caused by uneven distribution of washing materials during the dehydration process of the pulsator washing machine.

[0086] In the present embodiment, the radial distance from the first connecting port 6 on the collector 1 to the inner bucket wall is less than or equal to the radial distance from the second connecting port 4 on the water box 3 to the inner bucket wall.

[0087] The purpose of the above solution is to make the thrown-out water flow in the automatic balancing device under the action of smaller centrifugal force, thereby ensuring the normal operation of the automatic balancing device under low speed.

[0088] Further, the relative positions of the collector 1 and the water box 3 are as shown in Figure 3 The axial distance between the collector 1 and the bottom of the inner bucket is less than the axial distance between the water box 3 and the bottom of the inner bucket.

[0089] As a preferred embodiment based on the above technical solution, the structure of the water box 3 and the collector 1 is as shown in Figure 6 and Figure 7 The side of the collector 1 opposite to the direction of dehydration rotation of the inner bucket 7 is provided with the first connecting port 6, and the side of the water box 3 same as the direction of dehydration rotation of the inner bucket 7 is provided with the second connecting port 4.

[0090] Further, the first connecting port 6 is arranged close to the lowest position of the collector 1, and the second connecting port 4 is arranged close to the lowest position of the water box 3.

[0091] The above preferred embodiment can avoid that the thrown-out water is largely remained in the automatic balancing device, and avoid that the dehydration effect on the washing materials is affected.

[0092] Further, the first connecting port 6 and the second connecting port 4 are communicated through the water guide pipe 2.

[0093] Preferably, the water guide pipe 2 is fixedly installed on the inner drum wall.

[0094] On the basis of the above technical scheme, the collector 1 is further provided with a drainage port 5, which is arranged at the lowest position of the collector 1.

[0095] The drainage port 5 can avoid the residual water in the collector 1 after dehydration, prevent the backflow of the residual water into the inner drum 7, and affect the dehydration effect of the washing material.

[0096] After the dehydration step is started, the four collectors 1 arranged at equal intervals on the inner drum wall collect the water spun in different directions, respectively. At this time, most of the water spun under the action of centrifugal force flows out of the first connecting port 6 on the collector 1, flows into the water box 3 corresponding to each collector 1 through the water guide pipe 2 and the second connecting port 4, and is transferred to the water box 3 in the opposite direction of the eccentricity. The water spun in the opposite direction of the eccentricity is transferred to the water box 3 in the direction of the eccentricity, so as to realize the correction of the eccentricity.

[0097] In the above process, a small part of the water spun directly flows out of the drainage port 5, so as to prevent the water spun from gathering in the collector 1 and affecting the dehydration effect. The water in the water box 3 gathers at a position far away from the second connecting port 4 under the action of centrifugal force, so as to prevent the water spun from flowing back to the collector 1 from the second connecting port 4, and ensure the automatic balancing effect.

[0098] After the dehydration is completed, the dehydration drum starts to slow down. At this time, the water spun in the water box 3 approaches the second connecting port 4 under the action of inertia, and flows out of the second connecting port 4. Under the action of gravity and inertia, the water flows back to the collector 1 through the water guide pipe 2, and flows out of the drainage port 5 on the bottom surface of the collector 1, so as to avoid the backflow of the water spun into the inner drum and affect the dehydration effect of the washing material.

[0099] As another embodiment of the present application, the embodiment provides an automatic balancing washing machine, three groups of automatic balancing devices are arranged at equal intervals on the inner drum wall of the washing machine, and are used for correcting the eccentricity caused by the uneven distribution of the washing material in the dehydration process of the pulsator washing machine.

[0100] In the embodiment, the radial distance from the first connecting port 6 on the collector 1 to the inner drum wall is greater than or equal to the radial distance from the second connecting port 4 on the water box 3 to the inner drum wall.

[0101] The above scheme aims to make the water spun flow in the automatic balancing device under the action of smaller centrifugal force, and ensure the normal operation of the automatic balancing device in the low-speed state.

[0102] Preferably, the axial distance between the collector 1 and the inner drum bottom and the axial distance between the water box 3 and the inner drum bottom are the same.

[0103] The above preferred technical solution aims to ensure that the spun-out water is only affected by the centrifugal force and inertia when flowing to the water box 3, preventing the spun-out water from being unable to normally enter the water box 3 under the influence of gravity.

[0104] Further, the structure of the water box 3 and the collector 1 at this time is as shown in Figure 5 and Figure 7 The collector 1 is provided with a first connecting port 6 on the side opposite to the direction of dehydration rotation of the inner drum 7, and the water box 3 is provided with a second connecting port 4 on the side same as the direction of dehydration rotation of the inner drum 7.

[0105] Preferably, the first connecting port 6 is arranged close to the lowest part of the collector 1, and the second connecting port 4 is arranged close to the lowest part of the water box 3.

[0106] The above preferred embodiment can avoid a large amount of spun-out water remaining in the automatic balancing device, avoid affecting the dehydration effect on the washing objects, and also avoid increasing the running load of the washing machine.

[0107] A further solution is that the first connecting port 6 and the second connecting port 4 are communicated through a water guide pipe 2.

[0108] Preferably, the water guide pipe 2 is fixedly installed on the inner drum wall in a detachable manner.

[0109] Further, a drain port 5 is arranged on both the collector 1 and the water box 3, and the drain port 5 is arranged at the lowest part of the collector 1 and the water box 3.

[0110] The above technical solution can avoid the spun-out water remaining in the water box 3 and the collector 1, avoid increasing the running load of the washing machine, and also avoid the spun-out water flowing back to the inner drum to affect the dehydration effect on the washing objects.

[0111] After the dehydration step is started, the uneven distribution of the load in the drum causes the inner drum to produce eccentricity during rotation, and at this time, the amount of water spun out in each direction of the inner drum is not the same, and more water is spun out in the eccentric direction and relatively less water is spun out in other directions.

[0112] The three collectors 1 arranged at equal intervals on the inner drum wall collect spun-out water in different directions, and the collected spun-out water only flows out from the first connecting port 6 on the collector 1 under the action of the centrifugal force, flows through the water guide pipe 2, and flows into the water box 3 corresponding to each collector 1 through the second connecting port 4, the more spun-out water spun out in the eccentric direction is transferred to the water box 3 in the opposite direction of the eccentricity, and the less spun-out water spun out in the opposite direction of the eccentricity is transferred to the water box 3 in the eccentric direction, thereby realizing the correction of the eccentricity.

[0113] At this time, the water in the water box 3 is gathered at a position far from the second connecting port 4 under the action of centrifugal force, the spun-off water collected in the collector 1 is gathered near the first connecting port 6 under the action of centrifugal force, only a small part of the spun-off water flows out from the water outlet 5 on the water box 3 and the collector 1, the excessive spun-off water in the automatic balancing device does not affect the dehydration effect of the washing material, and most of the spun-off water does not flow out from the water outlet 5 on the water box 3 and the collector 1, so that the stability of the automatic balancing effect is ensured.

[0114] After the dehydration is completed, the dehydration tub starts to decelerate, at this time, the spun-off water in the water box 3 approaches the second connecting port 4 and the water outlet 5 arranged on the water box 3 under the action of inertia and gravity, part of the spun-off water flows out from the water outlet 5, and the other part of the spun-off water flows back to the collector 1 from the second connecting port 4 along the water guide pipe 2 under the action of inertia, and then flows out from the water outlet 5 on the collector 1, so that the spun-off water remaining in the automatic balancing device does not increase the operation burden of the washing machine.

[0115] As another embodiment of the present application, the embodiment provides an automatic balancing washing machine, two groups of automatic balancing devices are arranged on the inner tub wall of the washing machine at equal intervals, and are used for correcting the eccentricity caused by uneven distribution of washing materials in the dehydration process of the drum washing machine.

[0116] In the embodiment, the radial distance from the first connecting port 6 on the collector 1 to the inner tub wall is greater than or equal to the radial distance from the second connecting port 4 on the water box 3 to the inner tub wall.

[0117] The above technical scheme aims to ensure that the spun-off water can smoothly flow in the automatic balancing device and enter the water box 3 under the low-speed operation state of the washing machine, and avoid the failure of the automatic balancing device caused by the large amplitude shaking of the spun-off water in the water guide pipe under the action of gravity.

[0118] Further, the first connecting port 6 is arranged on the side of the collector 1 opposite to the direction of the dehydration rotation of the inner tub 7, and the second connecting port 4 is arranged on the side of the water box 3 same as the direction of the dehydration rotation of the inner tub 7.

[0119] In order to prevent the spun-off water in the water box 3 and the collector 1 from remaining too much, further, the first connecting port 6 is arranged close to the lowest part of the collector 1, and the second connecting port 4 is arranged close to the lowest part of the water box 3.

[0120] Further, the two ends of the water guide pipe 2 are respectively communicated with the first connecting port 6 and the second connecting port 4.

[0121] Preferably, the water guide pipe 2 is fixedly installed on the inner tub wall.

[0122] Further, in order to completely drain the collector 1 and the water box 3 after the dehydration is completed, the water outlet 5 is arranged on the collector 1 and the water box 3.

[0123] Preferably, the drain port 5 is arranged at the lowest position of the collector 1 and the water box 3.

[0124] After the dehydration step is started, due to the eccentricity caused by the uneven distribution of the laundry in the drum during the dehydration of the drum washing machine, the water spun out in different directions by the inner drum 7 is different, and the two collectors 1 distributed around the inner drum 7 collect the water spun out in different directions, respectively. The water spun out enters the first connecting port 6 under the action of the centrifugal force, and enters the water box 3 through the second connecting port 4 along the water guide pipe 2, thereby realizing the correction of the eccentricity of the drum.

[0125] At this time, the water spun out in the water box 3 is gathered at a position away from the second connecting port 4 in the water box 3 under the action of the centrifugal force, and the water spun out cannot be drained from the drain port 5, thereby ensuring the stability of the automatic balancing effect.

[0126] At the end of the dehydration, the rotation speed of the inner drum 7 decreases, and as the rotation speed of the inner drum decreases, part of the water spun out is drained from the drain port 5 on the water box 3, and the other part is returned to the collector 1 from the water guide pipe 2 and drained from the drain port 5 on the collector 1, thereby avoiding the residual of the water spun out in the water box 3, reducing the load of the washing machine during operation, and avoiding the influence of the water spun out on the dehydration effect of the washing material.

[0127] As another embodiment of the present application, the embodiment provides an automatic balancing washing machine for correcting the eccentricity of the washing machine.

[0128] Further, the washing machine is further provided with a balancing ring.

[0129] The embodiment further improves the range of the eccentricity that can be corrected by the automatic balancing through the cooperation of the balancing ring and the automatic balancing device, and expands the automatic balancing effect; meanwhile, the automatic balancing device eliminates the defects of the ordinary balancing ring structure that causes the eccentricity, and can correct the eccentricity during low-speed operation.

[0130] As another embodiment of the present application, the embodiment provides an automatic balancing washing machine for correcting the eccentricity of the washing machine.

[0131] Further, the automatic balancing device is an integrated automatic balancing device.

[0132] The integrated automatic balancing device has the advantages that: the integrated structure is more stable in installation, the water guide pipe 2 is more stable in fixation, the water spun out is not prone to flowing unsmoothly due to the shaking of the water guide pipe 2, thereby causing poor automatic balancing effect; and the relative positions of the collector 1 and the water box 3 are fixed, and the automatic balancing is more accurate.

[0133] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with the preferred embodiments as above, it is not intended to limit the present application, and any person skilled in the art can make some changes or modifications to the above-mentioned technical content with equivalent embodiments within the scope of the technical solutions of the present application.
