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] At present, the washing method of a pulsator washing machine is to turn the clothes by a special water flow formed by the rotation of the pulsator or the simultaneous rotation of the pulsator and the inner barrel, and exert force on them during the turning process, so that they are repeatedly washed through their own friction and the friction with the pulsator and the inner barrel wall to achieve the purpose of cleaning. The pulsator in the pulsator washing machine has a variety of shapes, such as disc-shaped pulsators, rod-shaped pulsators, bowl-shaped pulsators, etc., but no matter how the shape of the pulsator changes, its ultimate purpose is to improve the cleaning degree and reduce the entanglement of clothes without exception, and high cleaning degree and low entanglement rate are contradictory to each other. Often, the cleaning degree is improved and the entanglement is severe, or the entanglement is reduced and the cleaning degree is also reduced.

[0003] The existing pulsator washing machine consumes a lot of water, takes a long time to wash, uses a lot of detergent, and the clothes are easily tangled, resulting in uneven washing and easy deformation; or the clothes are washed by the impact of the water flow generated by the centrifugal force generated by the rotation of the inner drum, and the clothes are usually washed as a whole. Although the water flow also has a flushing effect, it is not enough to loosen the clothes, but makes the clothes form a ball and tangle together as a whole. Utility Model Content

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.

[0046] like Figures 1 to 3 As shown, Figure 1 A front view structural schematic diagram of a washing machine 10 provided in an embodiment of the present application is shown; Figure 2 A schematic diagram of the three-dimensional structure of a washing machine 10 provided in an embodiment of the present application is shown;

[0047] Figure 3 A left-side structural schematic diagram of a washing machine 10 provided in an embodiment of the present application is shown. The embodiment of the present application provides a washing machine 10, which includes a shell 100, an outer barrel 200, an inner barrel 300, a base 400, a pulsator 500 and a driving assembly 600.

[0048] The housing 100 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 100 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.

[0049] It should be understood that the washing machine 10 shown in this embodiment is a pulsator 500 washing machine 10 , but in other embodiments, the washing machine 10 may also be other types of washing machines 10 , such as a pulsator 500 washing machine 10 .

[0050] like Figure 4 As shown, Figure 4 Shows Figure 3 The schematic diagram of the cross-sectional structure cut along the A-A' section line in the figure; the outer barrel 200 is fixedly installed in the shell 100, and the outer barrel 200 is formed with a storage space with an upper opening to accommodate washing water. In addition, the barrel 200 can be set in the shape of a hollow cylinder, or other shapes. The inner barrel 300 is arranged in the outer barrel 200, and the inner barrel 300 is rotatably arranged in the storage space around the axis in the vertical direction, that is, the inner barrel 300 can be rotatably arranged in the outer barrel 200, and the inner barrel 300 has a washing cavity with an upper opening for washing and accommodating clothes.

[0051] Please refer to Figure 4 As shown, the inner tub 300 is formed with a water hole, which can be formed on the circumferential side wall of the inner tub 300. The washing cavity contains clothes, and the outer tub 200 is used to hold water and drain water. During the dehydration process, the water in the washing cavity can be discharged into the outer tub 200 through the water hole, and then discharged to the outside through the drain port of the outer tub 200.

[0052] It is worth mentioning that please continue to see Figure 4 As shown, the shell 100, outer barrel 200 and inner barrel 300 mentioned above are all arranged on a base 400, and the base 400 can be in direct contact with the ground; or, a plurality of supporting feet can be provided on the base 400, and the base 400 can be in contact with the ground through a plurality of supporting feet, or the base 400 can be in contact with the ground in other ways, which can be specifically designed according to different embodiments.

[0053] In addition, please continue to see Figure 4 As shown, the end of the inner barrel 300 away from the base 400 is provided with a balance ring 700, and the balance ring 700 is arranged at the opening of the washing chamber. The balance ring 700 can be made of plastic parts. The balance ring 700 formed by plastic parts has lower material cost and will not have the risk of rusting.

[0054] The balance ring 700 can be used to hold liquid substances or solid substances, the liquid substances include but are not limited to water or salt water, and the solid substances include but are not limited to spherical structures, etc. The balance ring 700 concentrates the liquid substances or solid substances in the opposite direction of the eccentricity of the inner barrel 300 to balance the eccentric mass of the inner barrel 300.

[0055] The balance ring 700 has an annular inner cavity inside, in which a liquid substance is encapsulated, and the balance ring 700 is coaxially arranged with the inner barrel 300. That is, the rotation axis of the balance ring 700 coincides with the rotation axis of the inner barrel 300. During the rotation of the inner barrel 300, the balance ring 700 can reduce or eliminate the eccentricity of the inner barrel 300 through the balance ring 700, so as to reduce the collision probability between the inner barrel 300 and the outer barrel 200 and reduce noise.

[0056] In some embodiments of the present application, the specific structure of the balance ring 700 is not limited, and the balance ring 700 includes a first ring shell (not shown in the figure) and a second ring shell (not shown in the figure), both of which are annular. The first ring shell forms a first annular opening groove with an open bottom side, and the second ring shell forms a first annular opening groove with an open top side. The first ring shell cover is arranged above the second ring shell, and the first opening groove and the second opening groove are jointly arranged to form a closed annular inner cavity. The first ring shell and the second ring shell are manufactured separately, which can simplify the mold of the first ring shell and the mold of the second ring shell, and reduce the design and manufacturing process of the first ring shell and the second ring shell. The ring platform is formed on the outer peripheral surface of the second ring shell, and the annular skirt is formed on the bottom surface of the second ring shell. The ring platform, the annular skirt and the second ring shell can be an integrally molded structure. This can reduce the assembly process and avoid water leakage between the various structures.

[0057] 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.

[0058] In addition, the balance ring 700 and the inner barrel 300 can be connected by threaded connection, rivets or other connection methods, as long as the balance ring 700 and the inner barrel 300 can rotate together.

[0059] See also Figure 4 and Figure 5 As shown, Figure 5 Shows Figure 4 The enlarged structural diagram of the rib 520 at B in the middle. The pulsator 500 is rotatably arranged at the inner bottom of the washing chamber, and is mainly used for scrubbing and turning the clothes.

[0060] See also Figure 6 As shown, Figure 6 A schematic structural diagram of an impeller 500 provided in an embodiment of the present application is shown; the impeller 500 includes a chassis 510 and a plurality of ribs 520 arranged on the chassis 510, and the spacing between adjacent ribs 520 is equal.

[0061] In order to drive the impeller 500 and the base 400 to rotate, please continue to refer to Figure 4As shown, the washing machine 10 also includes a driving assembly 600, which is arranged on the base 400. The driving assembly 600 includes a driving motor and an output shaft. The output shaft is extended on the axis of the inner barrel 300 and is connected to the impeller 500 and the inner barrel 300 by key connection, gear connection, etc.

[0062] It should be noted that the output shaft is independently connected to the inner barrel 300 and the pulsator 500. That is, the output shaft can control the pulsator 500 to rotate clockwise while also controlling the inner barrel 300 to rotate counterclockwise; the output shaft can control the pulsator 500 to rotate clockwise while also controlling the inner barrel 300 to rotate clockwise. That is, the output shaft can control the inner barrel 300 and the pulsator 500 to rotate in the same direction, or can control the inner barrel 300 and the pulsator 500 to rotate in opposite directions.

[0063] In some embodiments of the present application, the driving assembly 600 is arranged on the lower side of the impeller 500, and the bottom of the chassis 510 is provided with an insertion hole for inserting the output shaft, and the center of the chassis 510 is located on the axis of the inner barrel 300, that is, the center of the chassis 510 coincides with the axis of the inner barrel 300, thereby avoiding the gathering of clothes on one side of the chassis 510, so that the clothes are evenly distributed in the washing chamber, thereby ensuring the washing effect of the clothes.

[0064] Please continue to see Figure 6 As shown, the chassis 510 includes a central portion 511 and a main body 512. The central portion 511 corresponds to the insertion hole described above and is located on the side of the insertion hole away from the base 400. The central portion 511 is connected to the main body 512 in an arc. The arc connection between the central portion 511 and the main body 512 can effectively ensure that the clothes can be turned upside down on the axis of the inner barrel 300, and the clothes can be turned more smoothly.

[0065] To reduce the tangling rate of clothing, see Figure 6 and Figure 7 As shown, Figure 7 Shows Figure 6 The enlarged structural diagram of the connection between the main rib 521 and the secondary rib 522 at C in the middle; the rib 520 includes the main rib 521 and the secondary rib 522 connected to each other, and the main rib 521 and the secondary rib 522 are both extended from the center of the bottom plate 510 to the outer edge of the bottom plate 510, that is, the main rib 521 and the secondary rib 522 are ribs extending from the inside to the outside. The secondary rib 522 is arranged on the side of the main rib 521 away from the bottom plate 510, and the secondary rib 522 is arranged at the center of the main rib 521 close to the bottom plate 510. The main rib 521 is provided with a push position, which can push the clothes to move toward the center of the bottom plate 510 under the drive of the driving assembly 600.

[0066] The pushing position can push the clothes to the center of the chassis 510 under the drive of the driving assembly 600, that is, the clothes are pushed from the main body 512 of the chassis 510 to the central part 511 of the chassis 510, and driven by the secondary ribs 522, the clothes located in the central part 511 of the chassis 510 are driven to flip up and down in the axial direction of the washing chamber.

[0067] In this way, the present solution applies a relatively low rotation-stop ratio through the driving assembly 600 to drive the pulsator 500 to rotate, controls the main ribs 521 on the pulsator 500 to push the clothes from the edge of the chassis 510 to the center of the chassis 510, and drives the clothes to flip up and down in the axial direction of the inner barrel 300 through the secondary ribs 522, thereby reducing the large amount of clothes clumping, thereby reducing the entanglement of the clothes during the washing process, and achieving a low entanglement rate. In addition, by pushing the clothes from the edge of the chassis 510 to the center of the chassis 510, the friction between the clothes and the pulsator 500 and between the clothes can be increased, thereby improving the cleanliness of the clothes and reducing the wear rate of the clothes.

[0068] It is worth mentioning that when achieving low entanglement rate, low wear rate and high cleaning ratio of clothes, a lower rotation-stop ratio should be used to achieve a rotating blooming state of clothes around the center part 511 of the chassis 510 during the washing process.

[0069] Among them, the start-stop ratio can be 0.5 / 0.5 to 1.3 / 0.8, for example, 0.5 / 0.5, 1 / 0.8, 1.1 / 0.8, 1.2 / 0.8, 1.3 / 0.8, etc.

[0070] In some embodiments of this application, see Fig. 9 As shown, Fig. 9 The front view of the pulsator 500 provided in the embodiment of the present application is shown; in the direction from the center of the chassis 510 to the outer edge of the chassis 510, the height of the main rib 521 increases first and then decreases, and the highest point of the main rib 521 is the pushing position. By designing the main rib 521 to increase first and then decrease, it is ensured that the clothes can be pushed from the outer edge of the chassis 510 to the center of the chassis 510, so that the subsequent secondary ribs 522 drive the clothes to turn up and down.

[0071] It should be noted that the main rib 521 adopts a mirror-symmetrical structure and can be made of stainless steel or plastic.

[0072] Please continue to see Fig. 9 As shown, the distance from the highest point of the main rib 521 to the center of the bottom plate 510 is the first distance L1, and the ratio of the first distance L1 to the radius R of the bottom plate 510 ranges from 3 / 4 to 5 / 6. For example, the ratio of the first distance L1 to the radius R of the bottom plate 510 can be: 3 / 4, 19 / 24, 5 / 6, etc.

[0073] In addition, the main rib 521 includes a first top wall 5210 and a first wall 5211 and a second wall 5212 that are spaced apart in a circumferential direction of the bottom plate 510 .

[0074] See also Figure 7 As shown, the first wall 5211 and the second wall 5212 are connected to the first top wall 5210 at one side away from the bottom plate 510, and the first top wall 5210 is arranged around the outer edges of the first wall 5211 and the second wall 5212. In the axial direction of the bottom plate 510, the spacing between the first wall 5211 and the second wall 5212 gradually decreases, that is, the first wall 5211 and the second wall 5212 are inclined upward in the direction from the main body 512 of the bottom plate 510 to the opening of the washing chamber.

[0075] In addition, please continue to see Figure 7 As shown, in the radial direction of the chassis 510, the spacing between the first wall 5211 and the second wall 5212 also gradually increases, that is, the first wall 5211 and the second wall 5212 are enlarged in the direction from the center of the chassis 510 to the outer edge of the chassis 510. That is to say, the opposite side walls of the main rib 521 not only have a slope setting in the axial direction of the inner tub 300, but also have a curved slope setting in the radial direction of the inner tub 300. Since the first wall 5211 and the second wall 5212 have slope settings in both the axial and radial directions, the clothes located outside the pulsator 500 will be more easily pushed by the main rib 521, and the clothes will be driven into the center of the chassis 510, and it will be easier to push the clothes to turn up and down in the axial direction of the inner tub 300, thereby reducing the entanglement rate of the clothes, improving the washing ratio and reducing the wear rate of the clothes.

[0076] In addition, since the first top wall 5210 is connected to both the first wall 5211 and the second wall 5212, when the first wall 5211 and the second wall 5212 tend to expand in the direction from the center of the chassis 510 to the outer edge of the chassis 510, the surface area of ​​the first top wall 5210 gradually increases, so that the contact area between the main ribs 521 and the clothes increases in the direction from the center of the chassis 510 to the outer edge of the chassis 510, so that the outer main ribs 521 can have sufficient thrust to push the clothes into the center of the chassis 510.

[0077] It can be understood that this first top wall 5210 is arranged around the edges of the first wall 5211 and the second wall 5212. From the center of the chassis 510 to the outer edge of the chassis 510, this first top wall 5210 gradually rises and then gradually lowers. A highest point is provided on the first top wall 5210, and this highest point is the pushing position.

[0078] In some embodiments of the present application, the secondary rib 522 is disposed on a side of the primary rib 521 away from the bottom plate 510 , that is, the secondary rib 522 is disposed on the first top wall 5210 of the primary rib 521 .

[0079] The secondary ribs 522 are generally in the form of a tall rib 520 structure, and the main ribs 521 and the secondary ribs 522 are both connected to the arc of the center portion 511 described above, so as to ensure that the clothes can be flipped up and down in the axial direction of the inner barrel 300, thereby reducing the entanglement rate of the clothes.

[0080] Among them, see Figure 6 or Figure 8 As shown, Figure 8 Shows Figure 6 The enlarged structural diagram of the connection between the secondary rib 522 and the main rib 521 at D in the middle; the side of the secondary rib 522 away from the main rib 521 is provided with a second top wall 5220, that is, the second top wall 5220 is located on the upper top wall of the secondary rib 522. In the direction from the center of the chassis 510 to the outer edge of the chassis 510, the distance between the second top wall 5220 and the first top wall 5210 gradually decreases; that is, the second top wall 5220 has a downward trend in the direction from the center of the chassis 510 to the outer edge of the chassis 510.

[0081] Please continue to see Figure 8 As shown, in order to facilitate the clothes at the edge position to enter the secondary rib 522 under the drive of the main rib 521, the connection between the secondary rib 522 and the main rib 521 should be smoothly transitioned, which can be an inclined slope or a smooth arc surface, so as to ensure that the clothes can smoothly enter the secondary rib 522, and the secondary rib 522 can then push the clothes to flip up and down in the axial direction of the inner barrel 300.

[0082] In some embodiments of the present application, the connection between the second top wall 5220 and the first top wall 5210 is an arc connection, which makes it easier and more convenient to move clothes.

[0083] It should be noted that in the axial direction of the inner barrel 300, see Fig. 9 As shown, the highest point of the secondary rib 522 is lower than the highest point of the main rib 521. By making the highest point of the secondary rib 522 lower than the highest point of the main rib 521, it can effectively ensure that the clothes can enter the secondary rib 522 from the edge position, and the sliding action of the secondary rib 522 can be used to drive the clothes to flip up and down in the axial direction of the inner barrel 300.

[0084] Among them, see Fig. 9 As shown, the distance between the highest point of the main rib 521 and the surface of the chassis 510 is a second distance L2, and the value range of the second distance L2 is 35 mm to 45 mm, for example, 35 mm, 39 mm, 40 mm, 42 mm, and 45 mm.

[0085] The distance between the highest point of the secondary rib 522 and the surface of the chassis 510 is a third distance L3, and the value range of the third distance L3 is 35 mm to 45 mm, for example, 35 mm, 39 mm, 40 mm, 42 mm, and 45 mm.

[0086] It can be understood that the selection of the ratio range of the first distance L1 and the radius R of the impeller 500 and the selection of the second distance L2 and the third distance L3 have a certain positive effect on reducing the entanglement of clothes.

[0087] For example, when the second distance L2 is 40 mm and the third distance L3 is 37.5 mm, the ratio of the first distance L1 to the radius R of the chassis 510 is 5 / 6.

[0088] That is, by reasonably designing the ratio range of the first distance L1 and the radius R of the impeller 500 and the selection of the second distance L2 and the third distance L3, the clothing entanglement rate can be effectively reduced, the washing ratio can be improved, and the clothing wear rate can be reduced.

[0089] It is worth mentioning that see Figure 6 As shown, the washing machine 10 includes three groups of ribs 520, and the adjacent ribs 520 are spaced apart from each other, and the spacing distance between the adjacent ribs 520 is the same. The three groups of ribs 520 are spaced apart in the circumferential direction of the bottom plate 510, and the angle formed between the adjacent ribs 520 is 120°, which can effectively drive the clothes to be stirred inside the washing chamber, reduce the entanglement rate of the clothes, ensure the cleaning ratio of the clothes, and reduce the wear rate of the clothes.

[0090] Of course, the washing machine 10 may also include multiple groups of ribs 520, not limited to three groups of ribs 520, for example, four groups, five groups, six groups, etc.

[0091] The present application scheme drives the pulsator 500 to rotate in the washing chamber at a relatively low intensity turn-stop ratio. During the washing process, the clothes are pushed to the center of the chassis 510 by the pushing position on the main ribs 521, and are turned up and down along the axial direction of the inner barrel 300 under the fluctuation of the secondary ribs 522. In this way, the clothes are driven to turn up and down in the axial direction of the inner barrel 300, which can reduce the clumping of clothes, thereby reducing the entanglement of clothes during the washing process, increasing the friction between the clothes and the pulsator 500 and the clothes, and achieving the effects of low entanglement rate, high cleaning ratio and low wear rate.
