DETAILED DESCRIPTION

[0027] In order to make the purpose and implementation method of the present application clearer, the exemplary implementation method of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0028] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0029] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0030] The terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to all the components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0031] In the related art, the balance ring is connected to the top of the inner drum by screws, the balance ring is provided with screw columns, the inner drum is provided with screw holes, the screw columns are arranged at the lower side of the balance ring, and occupy a part of the volume of the inner chamber of the balance ring. When the inner drum rotates at a low speed, the balance liquid in the balance ring flows in the inner chamber of the balance ring, but the balance liquid cannot be distributed quickly and smoothly due to the obstruction of the screw columns during the flow process, thereby affecting the balance ability of the balance ring when it moves at a low speed. To solve this problem, the present application proposes a pulsator washing machine.

[0032] Figure 1 An inner drum assembly diagram of a pulsator washing machine according to some embodiments is shown.

[0033] See also Figure 1A pulsator washing machine includes a housing (not shown), a drum and a balance ring assembly 2. The housing may be an integral structure of the washing machine, and the housing is a hollow structure in which other components of the washing machine may be arranged, such as a circuit structure, a driving mechanism and a drainage structure. The housing may be in the shape of a hollow cuboid or a hollow cylinder, and is not limited to the above shapes.

[0034] The drum is arranged in the box body and is used for washing clothes. The drum body has a washing cavity. Clothes are put into the washing cavity through the clothes feeding port provided on the drum body for washing. Correspondingly, a door body is arranged on the box body, and the door body is arranged corresponding to the clothes feeding port. The door body is used to close the clothes feeding port of the drum body when washing clothes, so that the washing cavity is a closed space when washing clothes. A door glass can also be arranged on the door body to facilitate observation of the washing process.

[0035] The drum body may include an outer drum and an inner drum 1, the inner drum 1 is hollow to form a washing chamber, the inner drum 1 is arranged in the outer drum, the outer drum is arranged in the box, the axial direction of the inner drum 1 and the outer drum is arranged along the vertical direction, a water containing chamber for containing washing water is provided between the inner peripheral wall of the outer drum and the outer peripheral wall of the inner drum 1, and an opening is provided on the peripheral wall of the inner drum 1, the inner drum 1 is connected with the water containing chamber through the opening, the inner drum 1 can discharge washing water into the water containing chamber through the opening, and the washing water is discharged from the washing machine through the drainage structure connected to the outer drum, and at the same time, the washing water in the water containing chamber can also flow into the inner drum 1 through the opening to wash the clothes. The inner diameter of the opening is at least 4mm, and it is arranged in a flip hole form, which can avoid scratching the clothes while improving the water flow exchange efficiency between the inner and outer drums.

[0036] In some embodiments, a pulsator is also rotatably provided at the bottom of the inner drum 1, and there is a gap between the pulsator and the bottom of the inner drum 1. The pulsator rotates to stir the washing water in the inner drum 1 and drives the clothes to roll up and down to wash the clothes. Centrifugal force is generated during the rotation, causing the washing water to roll up and down.

[0037] In some embodiments, a plurality of first fixing holes 11 are spaced apart along the circumference of the top of the inner tube 1 . The plurality of first fixing holes 11 are evenly spaced and the number of the first fixing holes 11 is 6 to 8, and they are used for cooperating and fixing with the balance ring assembly 2 .

[0038] Figure 2 A schematic structural diagram of a balance ring assembly of a pulsator washing machine according to some embodiments is shown; Figure 3 A top view of a balance ring assembly of a pulsator washing machine according to some embodiments is shown; Figure 4 Shows Figure 3 Sectional view in the AA direction; Figure 5 Shows Figure 4 A partial enlarged view of point B in the middle.

[0039] Continue to see Figures 2 to 5In this embodiment, the balance ring assembly 2 includes a first balance ring 21 and a second balance ring 22. The first balance ring 21 covers the second balance ring 22, and the two are enclosed to form a balance ring cavity 23. The balance ring cavity 23 is filled with a balance liquid. The balance liquid can be salt water or pure water. Adding salt water can prevent freezing and prevent the balance ring from being unable to flow in a low temperature environment and unable to play a balancing role. The balancing principle of the balance ring is not repeated here. It is understandable that when the balance liquid is filled into the balance ring cavity 23, the filling amount should not be too full. Generally, it is filled to about 50% of the volume of the balance ring cavity 23. At this time, the balance liquid has good fluidity and can take into account the balancing effect.

[0040] Specifically, the first balance ring 21 includes a first outer wall 211, a top wall 212, and a first inner wall 213 connected in sequence. The first outer wall 211, the top wall 212, and the first inner wall 213 enclose a first annular concave cavity 214. The first outer wall 211 is away from the center of the first annular concave cavity 214 relative to the first inner wall 213, and is located outside the first balance ring 21. The second balance ring 22 includes a second outer wall 221, a bottom wall 222, and a second inner wall 223 connected in sequence. The second outer wall 221, the bottom wall 222, and the second inner wall 223 enclose a second annular concave cavity 224. The second outer wall 221 is away from the center of the second annular concave cavity 224 relative to the second inner wall 223, and is located outside the second balance ring 22. When the first balancing ring 21 and the second balancing ring 22 are covered, the first outer wall 211 and the second outer wall 221 are butted at one end, and the first inner wall 213 and the second inner wall 223 are butted at one end. At this time, the top wall 212 and the bottom wall 222 are arranged relatively to each other, and the center of the first annular cavity 214 and the center of the second annular cavity 224 are in the same axial direction, so that the first annular cavity 214 and the second annular cavity 224 are enclosed to form a balancing ring cavity 23. The balancing ring assembly 2 is formed by butting the first balancing ring 21 and the second balancing ring 22, so that the two can be manufactured separately, which is convenient for forming the internal structure of each, is conducive to mold forming, and simplifies the process.

[0041] In this embodiment, the first balance ring 21 is located on the side of the second balance ring 22 away from the bottom of the inner drum 1 . When the pulsator washing machine is placed flat on the ground, the first balance ring 21 is located on the upper side of the second balance ring 22 .

[0042] In some embodiments, a liquid injection port 215 is provided on the top wall 212 of the first balancing ring 21, and the liquid injection port 215 is connected to the interior of the first annular cavity 214, so that the balancing liquid can be injected into the balancing ring cavity 23 through the liquid injection port 215, and a balancing ring plug is detachably provided on the liquid injection port 215 to close or open the liquid injection port 215.

[0043] In this embodiment, a plurality of fixing columns 24 are provided on the first balancing ring 21 at intervals along its circumference, and the fixing columns 24 extend into the balancing ring cavity 23 along the radial direction of the first balancing ring 21. Specifically, the fixing columns 24 extend into the first annular concave cavity 214. By such an arrangement, the fixing columns 24 can have a longer extension length, a greater structural strength, and a higher connection stability. In addition, the fixing columns 24 avoid the second annular concave cavity 224, that is, avoid the lower area of ​​the balancing ring cavity 23. When the washing machine is dehydrated at a low speed, the influence on the flow of the balancing liquid mainly located in the lower and middle areas of the balancing ring cavity 23 is reduced, thereby ensuring rapid distribution of the balancing liquid during low-speed movement, thereby improving the balancing ability.

[0044] Furthermore, the fixing column 24 has a second fixing hole 25 along its length direction, and the second fixing hole 25 corresponds to the first fixing hole 11 formed on the top of the inner tube 1. The first balancing ring 21 is fixedly connected to the inner tube 1 through the fixing member passing through the first fixing hole 11 and the second fixing hole 25, thereby achieving a fixed connection between the balancing ring assembly 2 and the inner tube 1, and avoiding the influence of the fixing column 24 on the flow of the balancing liquid during low-speed movement.

[0045] In some embodiments, the first fixing hole 11 and the second fixing hole 25 are both screw holes, and the fixing members are screws, so that the first balance ring 21 is fixedly connected to the top of the inner cylinder 1 by screws passing through the screw holes. The connection structure is simple and firm, and is suitable for large-scale mass production.

[0046] It is understandable that, after the first balance ring 21 is fixedly connected to the top of the inner tube 1 , the second balance ring 22 is located inside the inner tube 1 , which can be achieved by appropriately extending the height of the top of the inner tube 1 .

[0047] In some embodiments, 6 to 8 fixing columns 24 are provided and are evenly spaced on the first balancing ring 21, thereby ensuring the connection strength between the first balancing ring 21 and the inner cylinder 1, making the force more uniform and avoiding stress concentration. Accordingly, 6 to 8 first fixing holes 11 are also provided.

[0048] In some embodiments, the fixing column 24 is disposed on a portion of the first balancing ring 21 that is away from the second balancing ring 22, that is, the fixing column 24 is disposed on the upper side of the first balancing ring 21, close to being attached to the top wall 212 of the first balancing ring 21. The farther the fixing column 24 is from the second balancing ring 22, the smaller the effect on the flow of the balancing liquid in the balancing ring cavity 23 is, because the balancing liquid is usually only half filled. After the inner cylinder 1 rotates at a low speed, even if the balancing liquid will appropriately go up on the side away from the center of the balancing ring cavity 23 due to the centrifugal force, it will not be blocked by the fixing column 24.

[0049] Figure 6 shows a schematic structural diagram of a second balancing ring according to some embodiments; Figure 7 A schematic structural diagram of a first balancing ring according to some embodiments is shown.

[0050] Continue to see Figure 6 and Figure 7 In some implementations, a plurality of partition ribs 26 are provided in the balance ring cavity 23 along its circumferential direction, and the partition ribs 26 divide the balance ring cavity 23 into a plurality of sub-cavities. The partition ribs 26 are provided with high-speed holes 263 and low-speed holes 264 that connect adjacent sub-cavities. The high-speed hole 263 is provided on the side of the low-speed hole 264 away from the center of the balance ring cavity 23, and the low-speed hole 264 is closer to the center of the balance ring cavity 23. The opening area of ​​the low-speed hole 264 is larger than the opening area of ​​the high-speed hole 263, so that when the inner cylinder 1 rotates at a low speed, the balance liquid mainly flows in the balance ring cavity 23 through the low-speed hole 264. When the speed of the inner cylinder 1 increases and the water is dehydrated at a high speed, the balance liquid increases due to the centrifugal force, and the part away from the center of the balance ring cavity 23 goes up, and the part flows in the balance cavity through the high-speed hole 263. By reasonably arranging the high-speed hole 263 and the low-speed hole 264, the flow of the balance liquid can be controlled to have a corresponding balance effect at different speeds.

[0051] In this embodiment, the fixing column 24 is located on the side of the high-speed hole 263 away from the bottom of the inner drum 1, that is, when the washing machine is placed flat on the bottom surface, the fixing column 24 is located on the upper side of the high-speed hole 263, and because the high-speed hole 263 is relatively small, the fixing column 24 will not affect the flow of the balancing liquid during high-speed movement, thereby improving the balancing effect of the balancing ring assembly 2 under various working conditions.

[0052] In some embodiments, the partition rib 26 includes a first partition 261 and a second partition 262. The first partition 261 is connected to the first balance ring 21 and can extend from the top wall 212 of the first balance ring 21 to the second balance ring 22. The second partition 262 is connected to the second balance ring 22 and can extend from the bottom wall 222 of the second balance ring 22 to the first balance ring 21. The first partition 261 and the second partition 262 are butted together to form the partition rib 26. The first partition 261 and the second partition 262 are integrally formed with the first balance ring 21 and the second balance ring 22, respectively. When the first balance ring 21 and the second balance ring 22 are butted together to form the balance ring assembly 2, the first partition 261 and the second partition 262 are synchronously butted together to form the partition rib 26.

[0053] Furthermore, the first and second partition plates 261 and 262 are provided with corresponding first and second grooves at their ends facing each other, and the first and second grooves are connected to form a high-speed hole 263. The first and second grooves can be the same in size and shape, such as rectangular grooves or semicircular grooves. The connection between the two makes the high-speed hole 263 a rectangular hole or a circular hole. Of course, it can also be other shapes. There are gaps between the first partition plate 261 and the inner wall of the first balance ring 21, and between the second partition plate 262 and the inner wall of the second balance ring 22. The gap forms a low-speed hole 264, so that the inner wall of the first balance ring 21 and the second balance ring 22 serve as one side inner wall of the low-speed hole 264, so that the low-speed hole 264 can be opened as large as possible. By setting the partition rib plate 26, it is convenient to form the high-speed hole 263 and the low-speed hole 264 to reasonably control the flow of the balancing liquid.

[0054] In some embodiments, at least one pair of corresponding first partition plates 261 and second partition plates 262 are provided with positioning posts 265 and positioning holes on their ends facing each other, and the positioning posts 265 are inserted into the positioning holes to allow the first balance ring 21 and the second balance ring 22 to dock, so as to facilitate the alignment of the two when docking, and the sizes of the positioning posts 265 and the positioning holes can be controlled, such as making the two have an interference fit, so as to fix the first balance ring 21 and the second balance ring 22. In this embodiment, positioning posts 265 and positioning holes are provided on both pairs of first partition plates 261 and second partition plates 262, and the two are arranged relative to each other along the circumference of the balance ring cavity 23, so as to achieve better positioning effect and more stable connection. It is understandable that the positioning posts 265 can be provided on the first partition plate 261, and the positioning holes are provided on the second partition plate 262, or the positioning posts 265 can be provided on the second partition plate 262, and the positioning holes are provided on the first partition plate 262.

[0055] In some embodiments, a plurality of reinforcing ribs 27 are provided at intervals along the circumference of the balance ring cavity 23, and the edges of the reinforcing ribs 27 are connected to the inner wall of the balance ring cavity 23, thereby increasing the structural strength of the inner wall of the balance ring cavity 23, and a through hole 271 is formed in the middle of the reinforcing rib 27, so that the balancing liquid can flow in the balance ring cavity 23 through the through hole 271. It is understandable that in order to reduce the barrier of the reinforcing rib 27 to the flow of the balancing liquid, the through hole 271 should be opened as large as possible, and the reinforcing rib 27 increases the structural strength of the balance ring cavity 23 by its edge portion.

[0056] In some embodiments, the reinforcing ribs 27 and the separating ribs 26 are alternately spaced along the circumference of the balancing ring cavity 23, so that the reinforcing ribs 27 and the separating ribs 26 are reasonably arranged to improve the structural strength of the balancing ring cavity 23 while reducing the impact on the flow of the balancing liquid.

[0057] In some embodiments, the reinforcing rib plate 27 includes a first reinforcing plate 272 and a second reinforcing plate 273. The first reinforcing plate 272 is connected to the first balance ring 21, and the second reinforcing plate 273 is connected to the second balance ring 22. The first reinforcing plate 272 and the second reinforcing plate 273 are connected to form the reinforcing rib plate 27. The first reinforcing plate 272 and the second reinforcing plate 273 respectively steam the structural strength of the inner wall of the balance ring cavity 23 connected to them.

[0058] In summary, in this embodiment, by arranging the fixed column 24 on the first balancing ring 21, especially on the part away from the second balancing ring 22, so as to be as far away from the bottom of the balancing ring cavity 23 as possible, without occupying the space in the lower part of the balancing ring cavity 23, and without blocking the flow of the balancing liquid, the fixed column 24 reduces the adverse effect on the rapid distribution of the balancing liquid during low-speed dehydration, and further, the fixed column 24 is higher than the high-speed hole 263, which can also reduce the adverse effect on the rapid distribution of the balancing liquid during high-speed dehydration, so that the balancing liquid can be more smoothly distributed in the balancing ring, thereby improving the balancing effect of the balancing ring assembly 2.
