Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of clothing processing, and in particular relates to a washing machine. Background Art
[0002] Clothes processing equipment such as a pulsator washing machine relies on a balance ring disposed on the inner barrel to maintain the eccentric balance of the clothes during the dehydration stage. Specifically, when the inner barrel rotates eccentrically, the water or other liquid in the balance ring is concentrated in the balance ring in the opposite direction of the eccentricity of the inner barrel, thereby balancing the eccentric mass of the inner barrel.
[0003] Currently, the existing balance ring and the inner barrel are fixed by screws or rivets, so that the balance ring can rotate synchronously with the inner barrel.

In the following description, many specific details are provided to provide a full understanding of the embodiments of the present application. However, those skilled in the art will appreciate that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps, etc. can be adopted. In other cases, known methods, devices, realizations or operations are not shown or described in detail to avoid blurring the various aspects of the application.
[0052] See also Figure 1 As shown, Figure 1 A schematic structural diagram of a washing machine provided in an embodiment of the present application is shown; an embodiment of the present application provides a washing machine 100 , which includes a housing 110 , an outer tub 120 , an inner tub 130 and a balance ring 140 .
[0053] The housing 110 is in the shape of a cylinder extending up and down, and is a rectangular structure as a whole; of course, it can also be in other shapes, such as a circle, a diamond, etc., which are not limited here. The housing 110 is a hollow structure, in which other component structures can be arranged, such as a circuit structure, a duct structure, a drive structure, a drainage structure, etc.
[0054] It should be understood that the washing machine 100 shown in this embodiment is a pulsator washing machine, but in other embodiments, the washing machine 100 may also be other types of washing machines, such as a pulsator washing machine.
[0055] The outer barrel 120 is fixedly installed in the housing 110, and the outer barrel 120 is formed with a storage space with an upper opening to accommodate washing water. In addition, the barrel 120 can be set in the shape of a hollow cylinder, or in other shapes. The inner barrel 130 is arranged in the outer barrel 120, and the inner barrel 130 is rotatably arranged in the storage space around an axis in the vertical direction, that is, the inner barrel 130 can be rotatably arranged in the outer barrel 120, and the inner barrel 130 has a washing cavity with an upper opening for washing and accommodating clothes.
[0056] It should be noted that the inner tub 130 is formed with a water hole, which can be formed on the circumferential side wall of the inner tub 130. The washing chamber contains clothes, and the outer tub 120 is used to hold water and drain water. During the dehydration process, the water in the washing chamber can be discharged into the outer tub 120 through the water hole, and then discharged to the outside through the drain port of the outer tub 120.
[0057] See also Figure 2 As shown, Figure 2 The schematic diagram of the structure of the inner barrel and the balance ring provided in the embodiment of the present application is shown; the balance ring 140 is arranged at the end of the inner barrel 130, and the balance ring 140 is arranged at the opening of the washing chamber. The balance ring 140 includes a balance body 141 and a ring platform 142 arranged around the outer circumference of the balance body 141. The ring platform 142 is formed with an insertion hole 1420. The hole depth direction of the insertion hole 1420 is parallel to the radial direction of the inner barrel 130, that is, the insertion hole 1420 is opened on the side wall of the ring platform 142 and extends to the inner barrel 130. See Figure 5 , Figure 8 , Fig. 9 and Fig.10 shown.
[0058] It is understandable that the insertion hole 1420 may also be disposed on the upper top surface or the lower bottom surface of the ring platform 142 , or may be disposed at other positions, and may be specifically designed according to different embodiments.
[0059] The balance ring 140 can be made of plastic. The material cost of the balance ring 140 formed of plastic is lower, and the balance ring 140 will not have the risk of rusting.
[0060] The balancing body 141 can be used to contain liquid substances or solid substances, the liquid substances include but are not limited to water or salt water, etc., and the solid substances include but are not limited to spherical structures, etc. The balancing body 141 concentrates the liquid substances or solid substances in the opposite direction of the eccentricity of the inner barrel 130 to balance the eccentric mass of the inner barrel 130.
[0061] The balance body 141 has an annular inner cavity inside, in which a liquid substance is encapsulated, and the balance body 141 is coaxially arranged with the inner barrel 130. That is, the rotation axis of the balance body 141 coincides with the rotation axis of the inner barrel 130. During the rotation of the inner barrel 130, the balance ring 140 can reduce or eliminate the eccentricity of the inner barrel 130 through the balance body 141, so as to reduce the collision probability between the inner barrel 130 and the outer barrel 120 and reduce noise.
[0062] In some embodiments of the present application, the specific structure of the balancing body 141 is not limited, and the balancing body 141 includes a first annular shell (not shown in the figure) and a second annular shell (not shown in the figure), both of which are annular. The first annular shell forms an annular first opening groove with an open bottom side, and the second annular shell forms an annular first opening groove with an open top side. The first annular shell cover is arranged above the second annular shell, and the first opening groove and the second opening groove are jointly arranged to form a closed annular inner cavity. The first annular shell and the second annular shell are manufactured separately, which can simplify the mold of the first annular shell and the mold of the second annular shell, and reduce the design and manufacturing process of the first annular shell and the second annular shell. The ring platform 142 is formed on the outer peripheral surface of the second annular shell, and the annular skirt is formed on the bottom surface of the second annular shell. The ring platform 142, the annular skirt and the second annular shell can be an integrally molded structure. This can reduce the assembly process and avoid water leakage between the various structures.
[0063] It should be noted that the first annular shell and the second annular shell can be sealed and connected by ultrasonic welding or fusion, etc., so as to ensure good sealing between the first annular shell and the second annular shell and avoid water leakage at the connection between the first annular shell and the second annular shell.
[0064] In addition, in order to tightly connect the balance body 141 and the inner barrel 130, the ring platform 142 and the inner barrel 130 are fixed by snaps, thereby reducing the use of screws and other fixings between the ring platform 142 and the inner barrel 130, reducing production costs, and avoiding the use of screws to ensure the integrity of the inner barrel 130 and the sealing of the inner barrel 130.
[0065] In some embodiments of this application, see Figures 3 to 7 As shown, the inner barrel 130 is provided with a limiting portion 131, which is extended along the radial direction of the inner barrel 130. The limiting portion 131 can be inserted into the insertion hole 1420 along the radial direction of the inner barrel 130 to achieve the buckle fixation between the inner barrel 130 and the balance ring 140. That is, the fixing between the inner barrel 130 and the balance ring 140 is achieved through the limiting portion 131 and the insertion hole 1420, so as to ensure that the balance ring 140 and the inner barrel 130 can rotate together, and limit the axial and circumferential movement of the balance ring 140 in the inner barrel 130.
[0066] In this way, the inner barrel 130 and the balance ring 140 are tightly connected by means of the stopper 131 and the insertion hole 1420, which can avoid the use of structures such as screws or rivets between the inner barrel 130 and the balance ring 140, avoid damage and deformation of the inner barrel 130, and ensure the sealing, integrity and strength of the inner barrel 130. In addition, the inner barrel 130 and the balance ring 140 are connected by means of the stopper 131 and the insertion hole 1420, and the connection point is firm and reliable, no raw material consumption, no other auxiliary materials are required, and the production cost is reduced. The riveting strength is high, and it can withstand large shear and tensile loads, which is suitable for the riveting of high-strength workpieces.
[0067] It is worth mentioning that the inner barrel 130 and the balance ring 140 can not only be aligned and matched in the radial direction of the inner barrel 130, but also in the axial or circumferential direction of the inner barrel 130, and the specific design can be carried out according to different embodiments.
[0068] For example, when the inner barrel 130 and the balance ring 140 are aligned and matched in the axial direction of the inner barrel 130, the depth direction of the insertion hole 1420 is the axial direction of the inner barrel 130, that is, the insertion hole 1420 is opened in the vertical direction, and the limiting portion 131 is aligned and matched in the axial direction of the inner barrel 130.
[0069] In another example, when the inner barrel 130 and the balance ring 140 are aligned and matched in the circumferential direction of the inner barrel 130, the insertion hole 1420 is located on the side wall of the ring platform 142, and the insertion hole 1420 is a long strip hole. The inner barrel 130 is provided with a limiting portion 131 corresponding to the insertion hole 1420, and the limiting portion 131 also adopts a strip structure, and the inner barrel 130 and the balance ring 140 are snap-fitted by rotational alignment.
[0070] It should be understood that the limiting portion 131 and the insertion hole 1420 are aligned and plugged in the radial direction of the inner barrel 130. Compared with the method of aligning and plugging the limiting portion 131 and the insertion hole 1420 in the axial direction of the inner barrel 130, the insertion method is simpler and there is no need to consider the opening size of the annular groove 132 described below.
[0071] Among them, see Figure 6 As shown, the top of the inner barrel 130 is formed with an annular groove 132 opening toward the inner side of the inner barrel 130, that is, the opening direction of the annular groove 132 faces the washing chamber. At least one limiting portion 131 is provided inside the annular groove 132, and the limiting portion 131 can be aligned and inserted into the insertion hole 1420 on the ring platform 142, so as to ensure the tightness of the connection between the balance body 141 and the inner barrel 130, reduce the use of fixing parts such as screws, and ensure the fixing effect.
[0072] It should be noted that the limiting portion 131 may be independently disposed in the annular groove 132 , or may be formed by the side wall of the annular groove, and may be specifically designed according to different embodiments.
[0073] For example, on the circumference of the inner barrel 130: at least one limiting portion 131 is provided on the inner wall of the annular groove 132, and this limiting portion 131 can be directly set on the inner wall of the annular groove 132 by snapping or bonding, and the limiting portion 131 is protruded toward the washing chamber.
[0074] In another example, the outer wall of the inner barrel 130 is recessed and protruded toward the inner wall to form the limiting portion 131, that is, the outer wall of the inner barrel 130 is recessed into the washing chamber. The limiting portion 131 is aligned with the insertion hole 1420 on the ring stage 142 and inserted into the ring stage 142 to limit the axial and circumferential movement of the balance ring 140 in the inner barrel 130.
[0075] In some embodiments of the present application, in the radial direction of the inner barrel 130 , the outer wall of the annular groove 132 protrudes inward to form a limiting portion 131 , so as to be aligned with the insertion hole 1420 to fix the balance ring 140 and the inner barrel 130 .
[0076] For an example, see Figure 6 , Fig.11 , Fig.12 and Fig.13 As shown, the annular groove 132 includes a first side wall 1320, a second side wall 1321 and a third side wall 1322, the first side wall 1320 and the third side wall 1322 are sequentially arranged in the axial direction of the inner barrel 130, and the second side wall 1321 is arranged around the periphery of the first side wall 1320 and the third side wall 1322, that is, the first side wall 1320 and the third side wall 1322 are connected through the second side wall 1321, and the second side wall 1321 is extended in the circumferential direction of the inner barrel 130. The second side wall is annular, and the first side wall 1320, the second side wall 1321 and the third side wall 1322 are jointly surrounded to form an annular space opening radially inwardly of the inner barrel 130, that is, the annular groove 132. The ring platform 142 extends into the annular space from the radial inner opening of the annular groove 132.
[0077] The second side wall 1321 is protruded toward the washing cavity of the inner barrel 130 to form a stopper 131. By using the second side wall 1321 in the radial direction of the inner barrel 130 to form the stopper 131, compared with the method of setting the stopper 131 and the insertion hole 1420 in the axial direction of the inner barrel 130, the insertion hole 1420 in the ring platform 142 and the stopper 131 formed by the second side wall 1321 can be inserted after alignment without adjusting the position of the balance ring 140, and the insertion method is simpler and more convenient, the assembly speed is faster, and the production cost is lower.
[0078] It is worth mentioning that the connection between the first side wall 1320 and the second side wall 1321 is rounded; and / or the connection between the third side wall 1322 and the second side wall 1321 is rounded.
[0079] In some embodiments of the present application, the connection between the first side wall 1320 and the second side wall 1321 is rounded, and the connection between the third side wall 1322 and the second side wall 1321 is rounded.
[0080] In some other embodiments of the present application, the connection between the first side wall 1320 and the second side wall 1321 is rounded, or the connection between the third side wall 1322 and the second side wall 1321 is rounded.
[0081] By setting the connection between the first side wall 1320 and the second side wall 1321 to be rounded; and / or setting the connection between the third side wall 1322 and the second side wall 1321 to be rounded, the collision damage between the inner barrel 130 and the outer barrel 120 can be reduced, and the integrity of the inner barrel 130 and the outer barrel 120 can be ensured.
[0082] Among them, this see Figure 5 As shown, the ring platform 142 includes a first wall 1421, a second wall 1422, and a third wall 1423 for connecting the first wall 1421 and the second wall 1422. The first wall 1421 and the second wall 1422 of the ring platform 142 are arranged in sequence in the axial direction of the inner barrel 130, and the third wall 1423 is arranged around the outer edges of the first wall 1421 and the second wall 1422, and the third wall 1423 is arranged in a circular ring. The third wall 1423 is provided with an insertion hole 1420 corresponding to the limiting portion 131, and the insertion hole 1420 is recessed into the inner barrel 130, that is, the wall surface of the third wall 1423 is recessed inward to form the insertion hole 1420. The insertion hole 1420 has the same shape as the limiting portion 131 or may have a different shape from the limiting portion 131. The limiting portion 131 is inserted into the insertion hole 1420 to prevent the limiting portion 131 from shaking in the insertion hole 1420, thereby preventing shaking between the balance ring 140 and the inner barrel 130.
[0083] It is worth mentioning that see Figure 5 As shown, the connection between the first wall 1421 and the third wall 1423 is rounded, and the connection between the second wall 1422 and the third wall 1423 is rounded. The rounded corners can avoid scratching the inner wall of the annular groove 132 when the annular platform 142 is aligned with the limiting portion 131 in the annular groove 132, thereby ensuring the integrity of the inner barrel.
[0084] In some embodiments of the present application, see Figure 4As shown, the first wall 1421 is connected to the first side wall 1320 of the annular groove 132, and the second wall 1422 is connected to the third side wall 1322 of the annular groove 132. In other words, the three side walls of the annular groove 132 can press the surface of the ring platform 142 to fix the balance ring 140 on the inner barrel 130. The three side walls of the annular groove 132 can limit the movement of the ring platform 142 in the axial and radial directions, reducing or eliminating the end jump and radial jump of the balance ring 140. When the limiting portion 131 extends into the insertion hole 1420, the inner barrel 130 and the balance ring 140 are locked. In other words, the limiting portion 131 can limit the balance ring 140 from rotating or moving radially relative to the inner barrel 130, so that the balance ring 140 and the inner barrel 130 always remain relatively stationary.
[0085] It is understandable that when the three side walls of the annular groove 132 press the ring platform 142, the limiting portion 131 and the insertion hole 1420 are aligned and inserted in the radial direction. Compared with the axial alignment and insertion of the limiting portion 131 and the insertion hole 1420, the alignment and insertion are not subject to the opening thickness of the annular groove 132, and the position of the limiting portion 131 is easier to find. The radial insertion method only requires the ring platform 142 with the insertion hole 1420 on one side to be aligned and inserted with the limiting portion 131, and then the ring platform 142 on the other side is pressed into the annular groove 132. The insertion method is simpler and more convenient. While ensuring the integrity, sealing and strength of the inner barrel 130, the use of structures such as screws is reduced, which reduces the production cost.
[0086] The sealing is achieved by the sealing contact between the annular platform 142 and the annular groove 132 and the close contact between the annular platform 142 and the three side walls, which can effectively prevent water leakage between the annular platform 142 and the annular groove 132 .
[0087] In some embodiments of the present application, the limiting portion 131 may be a circular ring structure, and the insertion hole 1420 has the same structure as the limiting portion 131, so as to ensure that the inner wall surface of the insertion hole 1420 abuts against the limiting portion 131 to limit the circumferential rotation and axial movement of the balancing ring 140. The limiting portion 131 extends into the insertion hole 1420, and the limiting portion 131 is in complete contact with the inner wall surface of the insertion hole 1420, so that the balancing ring 140 can be firmly assembled on the inner barrel 130, thereby reducing the noise generated during the operation of the washing machine 100, and eliminating the screws used to connect the balancing ring 140 and the inner barrel 130, thereby ensuring the integrity, sealing and strength of the inner barrel 130.
[0088] It can be understood that this limiting portion 131 adopts a circular ring structure, that is, the limiting portion 131 is an annular structure facing the washing chamber of the inner barrel 130, which can avoid the limiting portion 131 from causing damage to the ring platform 142 when the limiting portion 131 and the insertion hole 1420 are aligned and inserted into each other, thereby ensuring the integrity of the balance ring 140 and the tightness of the connection between the balance ring 140 and the inner barrel 130.
[0089] In addition, the limiting portion 131 may also adopt other structures, such as square, triangular and other structures, but is not limited thereto, as long as the balance ring 140 and the inner barrel 130 can be fixed.
[0090] In some embodiments of the present application, see Figure 6 As shown, the limiting portion 131 includes a first limiting surface 1310, a second limiting surface 1311 and a third limiting surface 1312. The third limiting surface 1312 and the first limiting surface 1310 are arranged in sequence in the axial direction of the inner barrel 130. The third limiting surface 1312 is connected to the first limiting surface 1310 through the second limiting surface 1311. The second limiting surface 1311 surrounds the outer edges of the first limiting surface 1310 and the third limiting surface 1312, that is, the second limiting surface 1311 is an annular surface. According to the above analysis, the use of this annular surface can avoid scratches caused when the ring stage 142 and the ring groove 132 are aligned, and the integrity of the ring stage 142 and the ring groove 132 can be ensured; and the alignment of the limiting portion 131 and the insertion hole 1420 using this annular surface is smoother, and the insertion of the limiting portion 131 and the insertion hole 1420 is simpler.
[0091] In some embodiments of the present application, Figure 6 As shown, in the direction from the outer barrel 120 to the inner barrel 130, the distance between the first limiting surface 1310 and the third limiting surface 1312 gradually decreases, that is, the first limiting surface 1310 and the third limiting surface 1312 are inclined slopes, and the inclined slopes can be used to reduce the fit between the limiting portion 131 and the insertion hole 1420. The limiting portion 131 is inserted into the insertion hole 1420 using the inclined slope, which is smoother and has a high degree of alignment.
[0092] In some embodiments of the present application, Figure 8 , Figures 11 to 13As shown, the number of the insertion holes 1420 and the limiting parts 131 is not limited. For example, in some embodiments, the number of the insertion holes 1420 and the limiting parts 131 can be one. In other embodiments, the number of the insertion holes 1420 can be one, and the number of the limiting parts 131 can be two, and the two limiting parts 131 extend into the same insertion hole 1420. In some other embodiments, the number of the insertion holes 1420 and the limiting parts 131 can be multiple, and the multiple insertion holes 1420 are evenly distributed along the circumferential interval of the ring platform 142, and each insertion hole 1420 corresponds to at least one limiting part 131. In this way, on the one hand, the riveting stability between the balance ring 140 and the inner barrel 130 is strengthened by the multiple insertion holes 1420 and the multiple limiting parts 131, so that each limiting part 131 is subjected to a balanced force, and the force of a single limiting part 131 is reduced; on the other hand, the structural strength of the annular groove 132 is further strengthened by the multiple limiting parts 131 to prevent the annular groove 132 from deforming during use.
[0093] In other embodiments of the present application, see Fig. 9 and Fig.13 As shown, the inner barrel 130 is provided with a plurality of groups of limiting parts 131, which are evenly spaced in sequence in the circumferential direction of the inner barrel 130, and each group of limiting parts 131 includes a plurality of mutually spaced limiting blocks, each limiting block corresponds to an insertion hole 1420, and each limiting block is formed by the second side wall 1321 of the annular groove 132 being recessed inwardly. In this way, the connection between the balance ring 140 and the inner barrel 130 can be increased to ensure that the balance ring 140 and the inner barrel 130 will not separate from each other, and the balancing effect of the balance ring 140 can be ensured.
[0094] In addition, if Figure 6 As shown, the portion of the inner barrel 130 located below the annular groove 132 partially contracts inward to form a tightening portion 133, and the balancing body 141 and the tightening portion 133 are arranged at intervals in the radial direction of the inner barrel 130. On the one hand, the balancing ring 140 is carried on the inner barrel 130, and the tightening portion 133 can strengthen the structural strength of the inner barrel 130, not only providing stable support for the balancing ring 140, but also reducing the vibration and noise of the inner barrel 130. On the other hand, the balancing body 141 and the tightening portion 133 are arranged at intervals in the radial direction to prevent the neck from contacting the balancing body 141, and to prevent the tightening portion 133 from squeezing the balancing body 141 during the roller pressing the annular groove 132, causing damage to the balancing body 141. On the other hand, during the use of the washing machine 100, such as during washing or dehydration, liquids such as water in the washing chamber tend to climb upward along the wall of the washing chamber under the action of centrifugal force, and the water climbs along the wall of the washing chamber to the inner surface of the tightening portion 133. The tightening portion 133 can block the liquid to a certain extent, preventing the liquid from continuing to climb upward and contacting the joint between the annular platform 142 and the annular groove 132. The tightening portion 133 plays a water-blocking role.
