Description

Washing machine with water-storage-free balance ring

Technical Field

The invention relates to the technical field of household equipment, in particular to a washing machine with a water-storage-free balance ring.

Background

The pulsator washing machine on the current market is easy to cause the laundry to be entangled during the operation process, thereby generating a large eccentricity. And then the vibration of the suspension part is large in the dehydration stage, even the suspension part impacts the box body to cause the vibration of the whole machine, and further a great amount of noise is generated. To address this problem, engineers have taken various damping measures, such as damping booms, systems for eccentricity detection control, etc., but the most widely used are liquid balance ring structures. The liquid balance ring structure is popular due to the characteristics of simple implementation, low cost, self-adaptive eccentric position and the like, but the liquid balance ring device has certain defects due to the principle reason. The liquid balance ring can play a certain eccentric compensation role only after the dehydration rotating speed of the washing machine exceeds the critical rotating speed, and the whole eccentricity can be increased under the low rotating speed state. Many researches are carried out to overcome the problem of the liquid balancing ring, such as adding ribs for partition at the lower part of the cavity of the balancing ring to reduce the liquidity of the liquid in a low-speed dehydration state. The method can reduce the adverse effect of the liquid balance ring to a certain extent, but cannot completely eliminate the adverse effect.

The invention patent with the application number of CN201320858572.4 discloses a balance ring assembly and a washing machine, and particularly discloses a balance ring assembly and a washing machine, wherein the balance ring assembly comprises a lower balance ring and an upper balance ring which is connected with the lower balance ring, the lower balance ring and the upper balance ring are connected together through hot plate welding, an annular chamber is formed between the upper balance ring and the lower balance ring for accommodating balance media, a storage space is formed outside the joint of the lower balance ring and the upper balance ring, and welding marks formed by the lower balance ring and the upper balance ring through hot plate welding are stored in the storage space. The balance ring assembly and the washing machine disclosed by the technical scheme can only play a certain eccentric compensation role after the dewatering rotating speed of the washing machine exceeds the critical rotating speed of the washing machine, and can increase the integral eccentricity under the state of low rotating speed, so that the vibration of a suspension part in the dewatering stage is large, and even the box body is impacted to cause the technical problem of damage.

In view of the above, the present invention is particularly proposed.

The present invention will be described in further detail with reference to examples.

As shown in fig. 1 to 9, a washing machine with a balance ring without water storage includes an inner tub 2 and a balance ring 1 fixedly installed on the inner tub 2, wherein the balance ring 1 includes a ring body 12 having a cavity 11 therein.

The inner barrel 2 is provided with a flow guide structure, the flow guide structure is internally provided with a flow guide cavity 21 for communicating the interior of the inner barrel 2 with the cavity 11, and part of water in the inner barrel 2 is guided into the cavity 11 of the balance ring 1 through the flow guide structure under the action of centrifugal force to play a balance role.

Further, as shown in fig. 7 to 8, the flow guiding structure includes a plurality of flow guiding channels 22 disposed at intervals along the circumferential direction of the inner barrel 2, and the flow guiding channels 22 are disposed along the axial direction of the barrel wall of the inner barrel 2 and gradually extend from bottom to top in an inclined manner.

Further, as shown in fig. 1 to 3, along the axial direction of the inner barrel 2, the water guide channel 22 is a pressed structure formed by gradually outwardly recessing a part of the barrel wall of the inner barrel 2, and a cavity inside the pressed structure forms the water guide cavity 21.

Further, the bottom wall 16 of the ring body 12 has an annular opening, an outlet end of the water guide channel 22 extends into the ring body 12 through the annular opening to communicate with the cavity 11, and part of water in the inner barrel 2 enters the cavity 11 through the water guide channel 22 under the action of centrifugal force.

Further, the ring body 12 is hollow and includes an outer peripheral wall 13, an inner peripheral wall 14 and a top wall 15 connected between the outer peripheral wall 13 and the inner peripheral wall 14, and a lower periphery of the outer peripheral wall 13 is folded and extended in a direction toward an outer peripheral wall surface of the inner tub 2 to form the bottom wall 16.

As shown in fig. 1-3 and 9, the inner peripheral edge 17 of the bottom wall 16 of the ring body 12 is spaced from the inner peripheral wall 14 to form the annular opening, and the diversion water channel 22 extends into the ring body 12 from the annular opening.

Further, as shown in fig. 1-2, an outer peripheral wall surface of the diversion water channel 22 and an inner peripheral edge 17 of the bottom wall 16 are spaced to form an annular water discharge opening 3, and water in the cavity 11 is discharged through the annular water discharge opening 3.

Further, as shown in fig. 3, the outer peripheral wall surface of the water guide channel 22 is fixedly connected to the inner peripheral edge 17 of the bottom wall 16, and a plurality of arc-shaped water discharge ports 3 are formed in gaps between the outer peripheral wall surface of the inner barrel 2 and the inner peripheral edge 17 of the bottom wall 16.

Further, as shown in fig. 1, the inner peripheral wall 14 of the ring body 12 is fixedly connected to the upper portion of the wall of the inner barrel 2.

Preferably, as shown in fig. 2-3, the balance ring 1 further includes an annular clamping wall 18 connected below the top wall 15 and spaced from the inner side peripheral wall 14 of the ring body 12, an annular clamping groove is formed between the inner side peripheral wall 14 of the ring body 12 and the annular clamping wall 18, and the upper portion of the bucket wall is clamped in the annular clamping groove.

Further preferably, the inner barrel 2 has an extending wall extending upward, and the extending wall is clamped in the annular clamping groove.

Further, the body of the cavity 11 is located close to the outer peripheral wall 13; alternatively, the space between the inner peripheral edge 17 of the bottom wall 16 and the outer peripheral wall 13 forms said cavity 11.

The water inlet gap 4 communicated with the cavity 11 is formed by the spacing spaces between the inner wall of the water guide channel 22 and the inner wall of the inner side peripheral wall 14 of the ring body 12 and between the upper end wall of the water guide channel 22 and the lower wall surface of the top wall 15.

Preferably, the flow guiding structure is integrally formed with the wall of the inner barrel 2.

Preferably, a plurality of mounting notches are uniformly arranged on the wall of the inner barrel 2 at intervals, and the flow guide structure is fixedly mounted on the mounting notches.

It should be understood that the diversion cavity 21 may be understood as a three-dimensional space, and the diversion channel 22 may be understood as a surface in the three-dimensional space. The water guide passage 22 is required to be disposed to meet the requirement of uniform disposition or balance disposition so that the washing machine is balanced in the high-speed dehydration process. The inclination angle of the diversion structure needs to meet certain requirements, and the water inlet rotating speed of the balance ring 1 is higher than the critical rotating speed of the system and is not higher than the set minimum stable dehydration rotating speed. The inclination angle has certain difference according to the different barrel diameters of the inner barrel 2, and needs to be designed and calculated according to actual conditions, and the inclination angle of the general pulsator washing machine is controlled to be 2-8 degrees, preferably about 5 degrees.

The inner side peripheral wall 14 of the ring body 12 can be directly and fixedly connected with the upper part (without a flow guide structure) of the barrel wall of the inner barrel 2, such as melting and fixedly connecting; the ring body 12 can be additionally provided with another inner side peripheral wall 14, namely an annular clamping wall 18, an annular clamping groove is formed between the inner side peripheral wall 14 of the ring body 12 and the annular clamping wall 18, and the upper part of the barrel wall is clamped in the annular clamping groove. Thereby realizing the detachable clamping connection of the balance ring 1 and the inner barrel 2.

The flow guide structure and the barrel wall of the inner barrel 2 are integrally formed, so that the manufacturing process can be reduced, and the cost is saved. Another implementation manner of the diversion structure is formed by combining the diversion structure with the installation gap of the inner barrel 2, so that the water inlet angle of the diversion water channel 22 can be flexibly adjusted, and the repair or replacement of parts and the like are facilitated.

As shown in fig. 1-3, after the clothes are washed, part of the water in the clothes is thrown out in the low-speed dehydration stage, and at this time, although some water enters the water channel, the water in the water channel cannot move upwards into the balance ring 1 due to insufficient centrifugal force caused by low rotation speed, and even if the water enters the ring body 12, the water flows out of the water outlet 3 due to insufficient centrifugal force, so the balance ring 1 is not effective in the low-speed stage. When the dehydration rotating speed is increased continuously and exceeds the critical rotating speed, part of water entering the diversion water channel 22 begins to climb along the inclined plane of the diversion water channel 22 and enters the cavity 11, and the water in the balancing ring 1 can be temporarily stored in the cavity 11 under the action of centrifugal force, so that the water in the cavity of the balancing ring 1 is kept and increased continuously and gradually starts to play a role in balancing. After the water in the balance ring 1 reaches a certain amount, the liquid level overflows the drain port 3 of the bottom wall 16 of the balance ring 1, the water amount in the balance ring 1 is kept constant, and the excessive entering water directly overflows from the drain port 3 of the balance ring 1. After the dehydration is finished, the rotating speed of the inner barrel 2 is gradually reduced to be static, and the water in the balance ring 1 is continuously discharged until the water is emptied.

It should be understood that the distinction between the so-called low-speed rotation phase of the inner tub and the high-speed rotation phase of the inner tub depends on the critical rotation speed, which may also be called the resonance point. In the conventional closed liquid balance ring, if the inner barrel tends to be eccentric to one side when the inner barrel rotates at a speed lower than the critical rotation speed, the balance liquid in the liquid balance ring flows to the eccentric side instead, so that the eccentric amount of the inner barrel to the side is further increased, and a more serious eccentric phenomenon occurs.

It should be noted that, in the prior art, in order to reduce the gap between the inner and outer barrels, the common balance ring 1 is generally installed at the inner side of the inner barrel 2 or a position close to the inner side of the inner barrel 2 to reduce the gap between the inner and outer barrels, but due to the design principle, the balance ring 1 must be installed at the outer side of the inner barrel 2, and in order to reduce the gap between the inner and outer barrels as much as possible, the shape of the balance ring 1 can be designed into a flat and thin annular belt shape, and the thickness can be reduced as much as possible while a certain capacity is ensured. The balance ring 1 can be arranged at the upper part of the inner barrel 2, and can also be arranged at the middle part or the bottom part of the inner barrel 2 according to different requirements.

Example one

As shown in fig. 2, 4-7 and 9, the pulsator washing machine having a balancing ring 1 without a water reservoir includes an inner tub 2 and the balancing ring 1 fixedly disposed on the inner tub 2, wherein the balancing ring 1 includes a ring body 12 having a cavity 11 therein.

As shown in fig. 7, the flow guiding structure further includes two flow guiding water channels 22 spaced along the circumferential direction of the inner barrel 2, and the flow guiding water channels 22 extend along the axial direction of the barrel wall of the inner barrel 2 from bottom to top and gradually incline outwards.

Further, along the axial direction of the inner barrel 2, the water guide channel 22 is a pressed structure formed by gradually outwardly recessing a part of the barrel wall of the inner barrel 2, and a cavity inside the pressed structure forms the water guide cavity 21.

Furthermore, the bottom wall 16 of the ring body 12 has an annular opening, outlet ends of the two water guide channels 22 extend into the ring body 12 through the annular opening to communicate with the cavity 11, and part of water in the inner barrel 2 enters the cavity 11 through the water guide channels 22 under the action of centrifugal force.

The inner peripheral edge 17 of the bottom wall 16 of the ring body 12 is spaced apart from the inner peripheral wall 14 to form the annular opening, and the water guide channel 22 extends into the ring body 12 from the annular opening.

Furthermore, the outer peripheral wall surface of the diversion water channel 22 and the inner peripheral edge 17 of the bottom wall 16 are arranged at intervals to form an annular water outlet 3, and water in the cavity 11 is discharged through the annular water outlet 3. It will be appreciated that the annular drain opening 3 is integrally connected.

The ring body 12 is detachably and fixedly connected with the upper part of the barrel wall of the inner barrel 2.

Further, the inner peripheral wall 14 of the ring body 12 is fixedly connected with the upper part of the barrel wall of the inner barrel 2.

Preferably, the balance ring 1 further includes an annular clamping wall 18 connected below the top wall 15 and spaced from the inner peripheral wall 14 of the ring body 12, an annular clamping groove is formed between the inner peripheral wall 14 of the ring body 12 and the annular clamping wall 18, and the upper portion of the bucket wall is clamped in the annular clamping groove.

It should be understood that the diversion cavity 21 may be understood as a three-dimensional space, and the diversion canal 22 may be understood as a surface in the three-dimensional space. The water guide passage 22 is required to be disposed to meet the requirement of uniform disposition or balance disposition so that the washing machine is balanced in the high-speed dehydration process. The inclination angle of the diversion structure needs to meet certain requirements, and the water inlet rotating speed of the balance ring 1 is higher than the critical rotating speed of the system and is not higher than the set minimum stable dehydration rotating speed. The inclination angle has certain difference according to the different barrel diameters of the inner barrel, and the inclination angle of the pulsator washing machine can be 4.5 degrees and needs to be designed and calculated according to actual conditions. The ring body 12 can be additionally provided with another inner side peripheral wall 14, namely an annular clamping wall 18, an annular clamping groove is formed between the inner side peripheral wall 14 of the ring body 12 and the annular clamping wall 18, and the upper part of the barrel wall is clamped in the annular clamping groove. Thereby realizing the detachable clamping connection of the balance ring 1 and the inner barrel 2. The flow guide structure and the barrel wall of the inner barrel 2 are integrally formed, so that the manufacturing process can be reduced, and the cost is saved.

As shown in fig. 2, 4-7 and 9, after the clothes are washed, in the low-speed dehydration stage, part of water in the clothes begins to be thrown out, and at this time, although part of water enters the water channel, the water in the water channel cannot move upwards to enter the balance ring 1 due to the low rotation speed and insufficient centrifugal force, and even if the water enters the ring body 12, the water flows out from the water outlet 3 due to insufficient centrifugal force, so that the balance ring 1 in the low-speed stage is not effective. When the dewatering rotation speed is increased continuously and exceeds the critical rotation speed, part of the water entering the diversion water channel 22 begins to climb along the inclined plane of the diversion water channel 22 and enters the cavity 11, and the water in the balance ring 1 is temporarily stored in the cavity 11 under the action of centrifugal force, so that the water quantity in the balance ring 1 is continuously reserved and increased, and the balance function is gradually started. After the water in the cavity of the balance ring 1 reaches a certain amount, the liquid level overflows the bottom wall 16 of the balance ring 1 at the water outlet 3, then the water amount in the balance ring 1 is kept to be certain, and the excessive water directly overflows from the water outlet 3 of the balance ring 1. After the dehydration is finished, the rotating speed of the inner barrel 2 is gradually reduced to be static, and the water in the balance ring 1 is continuously discharged until the water is emptied.

It should be noted that, in the prior art, in order to reduce the gap between the inner barrel and the outer barrel, a common balance ring 1 is generally installed at the inner side of the inner barrel 2 or a position close to the inner side of the inner barrel 2 to reduce the gap between the inner barrel and the outer barrel, but due to the design principle, the balance ring 1 must be installed at the outer side of the inner barrel 2, and in order to reduce the gap between the inner barrel and the outer barrel as much as possible, the shape of the balance ring 1 can be designed to be a flat and thin annular belt shape, and the thickness can be reduced as much as possible while ensuring a certain capacity. The balance ring 1 can be arranged at the upper part of the inner barrel 2, and can also be arranged at the middle part or the bottom part of the inner barrel 2 according to different requirements.

A plurality of water retaining ribs can be further arranged in the cavity 11, and preferably, the water retaining ribs are arranged on the inner surface of the outer side peripheral wall 13 of the cavity 11; the outer face of the outer side wall 13 of the ring body 12 further comprises a water-repelling structure, preferably a groove arranged on the outer face of the outer side wall 13 of the ring body 12.

Example two

As shown in fig. 3, 6, 8-9, the pulsator washing machine having a balancing ring 1 without a water reservoir includes an inner tub 2 and the balancing ring 1 fixedly disposed on the inner tub 2, wherein the balancing ring 1 includes a ring body 12 having a cavity 11 therein.

As shown in fig. 8, further, the flow guiding structure includes six flow guiding water channels 22 arranged at intervals along the circumferential direction of the inner barrel 2, and the flow guiding water channels 22 are arranged along the axial direction of the barrel wall of the inner barrel 2 and extend from bottom to top in an inclined manner.

As shown in fig. 9, the inner peripheral edge 17 of the bottom wall 16 of the ring body 12 is spaced apart from the inner peripheral wall 14 to form the annular opening, and the diversion water channel 22 extends into the ring body 12 from the annular opening.

As shown in fig. 3, an outer peripheral wall surface of the water guide channel 22 is fixedly connected to an inner peripheral edge 17 of the bottom wall 16, and six arc-shaped water discharge openings 3 are formed in gaps between the outer peripheral wall surface of the inner barrel 2 and the inner peripheral edge 17 of the bottom wall 16. The outer peripheral wall surface of the diversion water channel 22 is fixedly connected with the inner peripheral edge 17 of the bottom wall 16, so that the strength or rigidity of the balance ring 1 and the inner barrel 2 can be enhanced.

As shown in fig. 3, preferably, the balance ring 1 further includes an annular clamping wall 18 connected below the top wall 15 and spaced apart from the inner peripheral wall 14 of the ring body 12, an annular clamping groove is formed between the inner peripheral wall 14 of the ring body 12 and the annular clamping wall 18, and the upper portion of the tub wall is clamped in the annular clamping groove.

The water inlet gap 4 communicated with the cavity 11 is formed by the spacing spaces between the inner wall of the flow guide water channel 22 and the inner wall of the inner side peripheral wall 14 of the ring body 12 and between the upper end wall of the flow guide water channel 22 and the lower wall surface of the top wall 15.

It should be understood that the diversion cavity 21 may be understood as a three-dimensional space, and the diversion canal 22 may be understood as a surface in the three-dimensional space. The water guide passage 22 is required to be disposed to meet the requirement of uniform disposition or balance disposition so that the washing machine is balanced in the high-speed dehydration process. The inclination angle of the diversion structure needs to meet certain requirements, and the water inlet rotating speed of the balance ring 1 is higher than the critical rotating speed of the system and is not higher than the set minimum stable dehydration rotating speed. The inclination angle has certain difference according to the difference of the barrel diameters of the inner barrel 2, and needs to be designed and calculated according to actual conditions, and the inclination angle of the pulsator washing machine in the embodiment is 6.5 degrees. The ring body 12 can be additionally provided with another inner side peripheral wall 14, namely an annular clamping wall 18, an annular clamping groove is formed between the inner side peripheral wall 14 of the ring body 12 and the annular clamping wall 18, and the upper part of the barrel wall is clamped in the annular clamping groove. Thereby realizing the detachable clamping connection of the balance ring 1 and the inner barrel 2.

Another implementation manner of the diversion structure is formed by combining the diversion structure with the installation gap of the inner barrel 2, so that the water inlet angle of the diversion water channel 22 can be flexibly adjusted, and the repair or replacement of parts and the like are facilitated.

As shown in fig. 3, after the laundry is washed, part of the water in the laundry begins to be thrown out in the low-speed dehydration stage, and at this time, although part of the water enters the water channel, the water in the water channel cannot move upwards into the balance ring 1 due to insufficient centrifugal force caused by low rotation speed, and even if the water enters the ring body 12, the water flows out of the water outlet 3 due to insufficient centrifugal force, so the balance ring 1 in the low-speed stage is not effective. When the dewatering rotation speed is increased continuously and exceeds the critical rotation speed, part of the water entering the diversion water channel 22 begins to climb along the inclined plane of the diversion water channel 22 and enters the cavity 11, and the water in the balance ring 1 is temporarily stored in the cavity 11 under the action of centrifugal force, so that the water quantity in the balance ring 1 is continuously reserved and increased, and the balance function is gradually started. After the water in the cavity of the balance ring 1 reaches a certain amount, the liquid level overflows the bottom wall 16 of the balance ring 1 at the water outlet 3, then the water amount in the balance ring 1 is kept to be certain, and the excessive water directly overflows from the water outlet 3 of the balance ring 1. After the dehydration is finished, the rotating speed of the inner barrel 2 is gradually reduced to be static, and the water in the balance ring 1 is continuously discharged until the water is emptied.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
