Description

Technical Field

[0001] This invention belongs to the field of washing equipment technology, specifically, it relates to a tub assembly of a washing equipment and the washing equipment itself. Background Technology

[0002] With the accelerating pace of modern life and people's ever-increasing demands for quality of life, washing machines, as an essential household appliance, have gradually become the focus of consumers' attention due to their diverse performance and functions.

[0003] Traditional top-loading washing machines achieve their cleaning effect by either rotating the pulsator independently or by having the pulsator rotate relative to the inner tub to agitate the washing water and clothes, utilizing the friction between the clothes and the pulsator. To further enhance cleaning capabilities, existing technologies have proposed incorporating washing blocks on the tub. These blocks can strengthen the agitation of the washing water and clothes, as well as the friction applied to the clothes.

[0004] However, the washing pads currently used on the tub are usually fixed, which has limited effect on improving washing ability and cannot meet the diverse washing needs of different users.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art.

[0024] Preferably, the washing auxiliary component has:

[0025] The sliding plate body is mounted on the inner side of the washing tub wall, which can move up and down;

[0026] The first assembly part extends upward from the upper part of the skateboard body and has a hollow structure inside;

[0027] The first assembly part is movably inserted into the fixed base; the upper end of the first elastic member abuts against the fixed base, and the lower end passes through the internal hollow structure of the first assembly part and abuts against the slide body.

[0028] More preferably, the slide body has a protruding stop on the side facing the barrel wall, and the lower end of the first elastic member abuts against the stop.

[0029] Furthermore, the washing auxiliary component has:

[0030] An auxiliary washing slide plate is mounted on the wall of the washing tub, which can move up and down.

[0031] A support component is disposed at the lower part of the auxiliary washing slide plate and is connected to the auxiliary washing slide plate in a way that allows it to move up and down.

[0032] A buffer is provided between the auxiliary washing slide and the support member, so that the lower end of the support member remains in contact with the support member;

[0033] Preferably, the buffer includes a second elastic element that provides a downward elastic force to the support member;

[0034] Preferably, the lower end of the support member has a rolling element; the washing tub rotates relative to the support member, and the rolling element rolls along the support surface of the support member;

[0035] Preferably, the auxiliary washing slide plate has an auxiliary washing protrusion on the side facing the inside of the washing tub.

[0049] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0050] In this invention, the washing auxiliary component moves up and down relative to the washing tub during the washing process, which enhances the tumbling effect of the clothes in the tub and improves the washing performance. The mating parts ensure that the washing auxiliary component remains in contact with the support, thus achieving a more stable fit and preventing the washing auxiliary component from separating from the support due to the resistance of the clothes or water, which would prevent it from continuing to move up and down on the washing tub and thus failing to play its auxiliary washing role.

[0051] In this invention, the buffer component makes the overall movement of the washing auxiliary component smoother. On the other hand, when the upper auxiliary washing slide plate is affected by the clothes and does not descend in time, the buffer component drives the support component to descend relative to the auxiliary washing slide plate, so that the lower end of the support component always stops against the support surface, avoiding the problem of abnormal noise caused by the support component suddenly descending and colliding with the support surface.

[0052] In this invention, the first elastic member and the second elastic member are respectively disposed in the hollow first assembly part and the second assembly part, instead of being directly exposed in the washing space where they can come into contact with the clothes. This avoids the problem of rubbing against the clothes or failure due to a large number of lint hooks, making the structure more reliable.

[0053] In this invention, the diameter of the support member is not greater than the outer diameter of the bottom of the washing tub, so that the support member does not extend beyond the outer periphery of the washing tub 100 in the radial direction and does not occupy the outer periphery space of the washing tub. This avoids the problem of compressing the volume of the washing tub due to the setting of the support member, or the need to increase the overall size of the machine.

The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0079] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0080] like Figures 1 to 19 As shown, embodiments of the present invention provide a tub assembly for a washing device, and a washing device having the tub assembly. The washing device refers to an electrical device with a clothing washing function.

[0081] Specifically, the tub assembly described in this embodiment includes a washing tub 100 and a washing auxiliary component 500. The washing auxiliary component 500 is movably mounted on the washing tub 100. During the washing process, the washing auxiliary component 500 moves up and down relative to the washing tub 100, and achieves the purpose of assisting washing and improving the washing effect by contacting the clothes.

[0082] In one specific embodiment, the tub assembly includes a water tank (not shown in the figure), a washing tub 100 rotatably disposed inside the water tank, and a pulsator 110 at the bottom of the washing tub 100. During the washing process, the water tank is used to hold water, the washing tub 100 holds clothes, the pulsator 110 rotates relative to the washing tub 100, and simultaneously the washing auxiliary component 500 moves up and down relative to the washing tub 100 to wash the clothes.

[0083] In this embodiment, the tub assembly is provided with a support member 300, which cooperates with the washing auxiliary component 500 to guide the washing auxiliary component 500 to move up and down relative to the washing tub 100.

[0084] Specifically, the washing auxiliary component 500 is movable up and down on the tub wall 120 of the washing tub 100, and the support member 300 is rotatably mounted relative to the washing tub 100, so that the washing auxiliary component 500 can be moved up and down along the tub wall 120 by the relative rotation of the washing tub 100 and the support member 300.

[0085] The washing aid component 500 moves up and down along the tub wall 120 of the washing tub 100 during the washing process. On the one hand, it can contact the clothes to enhance the tumbling effect of the clothes in the tub, thereby improving the washing performance. On the other hand, it can also increase the friction on the clothes, further enhancing the washing effect.

[0086] In one specific embodiment, the support member 300 has a support surface 331 that extends continuously along the circumference of the washing tub 100 and has a varying height, and the washing auxiliary component 500 contacts the support surface 331. When the washing tub 100 and the support member 300 rotate relative to each other, the washing auxiliary component 500 is fixed relative to the washing tub 100 in the circumferential direction, thereby being able to move along the support surface 331 and move up and down relative to the washing tub 100 as the height of the support surface 331 changes.

[0087] However, since the washing aid component 500 is in direct contact with the clothes and water inside the washing tub 100, the clothes and water will create resistance to the movement of the washing aid component 500. This may cause the washing aid component 500 to separate from the support surface 331 and not be effectively guided by the support surface 331. It may even cause the washing aid component 500 to get stuck and lose its washing aid effect.

[0088] To address the aforementioned problems, this embodiment further employs the following technical solution.

[0089] In this embodiment, the tub assembly is provided with a mating part 600, which is disposed between the washing tub 100 and the washing auxiliary component 500. When the washing tub 100 and the support member 300 rotate relative to each other, the washing auxiliary component 500 and the support member 300 can be kept in contact through the mating part 600, so that the washing auxiliary component 500 can be stably mated with the support member 300.

[0090] In one specific embodiment, the mating component 600 includes a first elastic member 610, which keeps the washing auxiliary component 500 in contact with the support member 300 through the elastic force of the first elastic member 610.

[0091] In one specific structure of this embodiment, the support member 300 is disposed on the lower side of the washing tub 100, and the first elastic member 610 provides a downward elastic force to the washing auxiliary assembly 500, thereby causing the lower end of the washing auxiliary assembly 500 to abut against the support surface 331. Thus, when the washing tub 100 and the support member 300 rotate relative to each other, the lower end of the washing auxiliary assembly 500 can move along the support surface 331, driving the entire washing auxiliary assembly 500 to move up and down along the tub wall 120 of the washing tub 100.

[0092] In the above solution, the first elastic element 610, which provides elasticity to the washing auxiliary component 500, has a simple structure and ensures that the lower end of the washing auxiliary component 500 always abuts against the support surface 331, preventing the washing auxiliary component 500 from separating from the support surface 331 due to the resistance of clothes or water. Thus, during the washing process, the washing auxiliary component 500 can stably reciprocate up and down with the cooperation of the support element 300 and the first elastic element 610, effectively improving the washing effect of clothes.

[0093] In one specific embodiment, the support member 300 is disposed between the washing tub 100 and the water tank, and the support surface 331 is formed at the upper end of the support member 300, which is wavy in the circumferential direction. When the support member 300 and the washing tub 100 rotate relative to each other, the lower end of the washing auxiliary component 500 moves from the trough to the crest along the support surface 331, and the entire washing auxiliary component 500 rises along the tub wall 120. After the lower end of the washing auxiliary component 500 reaches the crest of the support surface 331, the support member 300 and the washing tub 100 continue to rotate relative to each other, and the lower end of the washing auxiliary component 500 begins to turn from the crest to the trough of the support surface 331. At this time, the washing auxiliary component 500 overcomes the resistance of the clothes and water and begins to move downward under its own weight and the elastic force of the first elastic member 610.

[0094] The washing equipment provided in this embodiment has a drive unit 400 disposed below the washing tub 100. The drive unit 400 specifically includes a motor 410 for providing driving force, and a reduction clutch 430 for transmitting power from the motor 410 to the impeller 110, the washing tub 100, and the support member 300. The reduction clutch 430 includes an input shaft, an input shaft sleeve, a torque transmission shaft sleeve, a clutch mechanism, a lower end housing, an upper end housing 420, a brake wheel, a gear train, a braking mechanism, bearings, a water seal, and several output shafts. The braking mechanism includes a brake band and a brake arm 434, which controls the brake band to engage or disengage the brake wheel.

[0095] To achieve the aforementioned washing process, the reduction clutch 430 in this embodiment is equipped with three output shafts: an impeller shaft 431 connected to the impeller 110, a spin-drying shaft 432 connected to the washing tub 100, and a fixed shaft 433 connected to the support member 300. The spin-drying shaft 432 is sleeved outside the impeller shaft 431, and the fixed shaft 433 is sleeved outside the spin-drying shaft 432.

[0096] The input shaft of the reduction clutch 430 is connected to the motor 410 and receives the driving force provided by the motor 410. The impeller shaft 431, the dehydration shaft 432, and the fixed shaft 433 are connected to the input shaft through a gear train, thereby driving the impeller 110, the dehydration shaft 432, and the fixed shaft 433 to achieve different motion modes.

[0097] In one specific implementation, during washing, the brake band grips the brake wheel, fixing the fixed shaft 433 in place. The gear train of the deceleration clutch 430 drives the impeller shaft 431 and the spin-drying shaft 432 to rotate in opposite directions. Thus, the impeller 110 and the washing tub 100 rotate in opposite directions, the support member 300 remains fixed, and the washing auxiliary component 500 rotates synchronously with the washing tub 100 and, guided by the support surface 331 and under the elastic force of the first elastic member 610, reciprocates up and down along the tub wall 120.

[0098] During spin-drying, the brake band releases the brake wheel, and the gear train of the deceleration clutch 430 drives the impeller shaft 431, the spin-drying shaft 432, and the fixed shaft 433 to rotate together, causing the impeller 110, the washing tub 100, and the support member 300 to rotate synchronously, thus realizing the spin-drying process. Since the support member 300 and the washing tub 100 rotate synchronously at this time, the washing auxiliary component 500 remains relatively stationary on the washing tub 100.

[0099] It should be noted that the gear train of the deceleration clutch 430 in this embodiment can adopt the gear train structure of an existing three-power deceleration clutch device to achieve the above-mentioned working process.

[0100] Furthermore, in the reduction clutch 430 of this embodiment, a first water seal 441 is provided between the impeller shaft 431 and the dehydration shaft 432, a second water seal 442 is provided between the dehydration shaft 432 and the fixed shaft 433, and a third water seal 443 is provided between the fixed shaft 433 and the upper end housing 420. In this way, water can be prevented from seeping into the interior of the reduction clutch 430.

[0101] In a first specific embodiment of this example, the first elastic element 610 includes a compression spring disposed on the upper part of the washing auxiliary assembly 500. One end of the compression spring is fixed relative to the washing tub 100, and the other end is fixed relative to the washing auxiliary assembly 500. When the washing auxiliary assembly 500 moves upward relative to the washing tub 100, it compresses the compression spring, causing the compression spring to generate downward elastic pressure. When the washing auxiliary assembly 500 moves from the crest of the support surface 331 to the trough, the compression spring gradually elongates under its own elasticity, thereby pushing the washing auxiliary assembly 500 downward with the support surface 331, so that the lower end of the washing auxiliary assembly 500 always abuts against the support surface 331.

[0102] In a preferred embodiment, the compression spring is in a compressed state when the washing auxiliary component 500 moves to its lowest position on the washing tub 100. That is, during the up-and-down movement of the washing auxiliary component 500 relative to the washing tub 100, the compression spring remains compressed, exerting a downward elastic pressure on the washing auxiliary component 500. This ensures a more effective and reliable fit between the washing auxiliary component 500 and the support surface 331, preventing easy separation from the support surface 331.

[0103] In a second specific embodiment of this example, the first elastic element includes a tension spring disposed at the lower part of the washing auxiliary assembly. One end of the tension spring is fixed relative to the washing tub, and the other end is fixed relative to the washing auxiliary assembly. When the washing auxiliary assembly moves upward relative to the washing tub, it stretches the tension spring, causing the spring to generate a downward elastic force. When the washing auxiliary assembly moves from the crest of the support surface to the trough, the tension spring gradually shortens due to its own elasticity, thereby pulling the washing auxiliary assembly downward with the support surface, ensuring that the lower end of the washing auxiliary assembly always abuts against the support surface.

[0104] In the preferred embodiment, the tension spring is in an extended state when the washing auxiliary component moves to its lowest position on the washing tub. That is, during the up-and-down movement of the washing auxiliary component relative to the washing tub, the compression spring is always stretched, generating a downward elastic force on the washing auxiliary component. This ensures a more effective and reliable fit between the washing auxiliary component and the support surface, preventing easy separation.

[0105] In the third specific embodiment of this example, the tension spring and compression spring described above can also be provided simultaneously. That is, the upper part of the washing auxiliary component is subjected to a downward elastic pressure, and the lower part is subjected to a downward elastic tension. The two elastic forces work together to make the lower end of the washing auxiliary component abut against the support surface, making it more stable and reliable.

[0106] Similar to the previous two specific implementation methods, in the preferred embodiment, when the washing auxiliary component moves to its lowest position on the washing tub, the compression spring is in a compressed state and the tension spring is in an extended state. The tension and compression springs always exert a certain elastic force on the washing auxiliary component, ensuring the stable movement of the washing auxiliary component.

[0107] In a further embodiment, the upper part of the washing tub 100 is provided with a fixed seat 150, and a first elastic member 610 is disposed between the fixed seat 150 and the washing auxiliary component 500. The elastic force provided by the first elastic member 610 pushes the washing auxiliary component 500 downward and away from the fixed seat 150.

[0108] As a specific structure, the upper end of the washing tub 100 is provided with a balance ring 140, and the fixing seat 150 is installed on the inner side of the tub wall 120 of the washing tub 100, located below the balance ring 140.

[0109] Furthermore, the washing auxiliary assembly 500 of this embodiment includes an auxiliary washing slide plate 510 and a slide plate base 530. The auxiliary washing slide plate 510 is vertically movable and mounted on the tub wall 120 of the washing tub 100 to contact the clothes inside the tub and assist in washing. The slide plate base 530 is located on the outside of the tub wall 120, passes through the tub wall 120, and connects to the auxiliary washing slide plate 510, thereby mounting the washing auxiliary assembly 500 on the tub wall 120.

[0110] In the preferred configuration, the auxiliary washing slide plate 510 has an auxiliary washing protrusion 5111 on the side facing the inside of the washing tub 100 to enhance the effect of tumbling the clothes.

[0111] More specifically, the auxiliary washing slide plate 510 has a slide plate body 511 disposed inside the tub wall 120 of the washing tub 100, and a first mounting part 512 formed by extending upward from the upper part of the slide plate body 511, and a slide plate seat 530 passing through the tub wall 120 and connected to the slide plate body 511.

[0112] The first assembly part 512 is movably inserted into the fixed base 150, allowing the slide body 511 to move up and down inside the tub wall 120 to contact the clothes, thereby achieving an auxiliary washing effect. The auxiliary washing protrusion 5111 is located on the side of the slide body 511 facing the inside of the washing tub 100, thereby increasing the friction on the clothes through contact with the clothes, enhancing the tumbling effect of the clothes in the tub, and thus improving the washing performance.

[0113] In one specific structure, the auxiliary washing protrusions 5111 are horizontally extending strip-shaped protrusions, with multiple protrusions spaced apart along the height direction. The extending direction of the auxiliary washing protrusions 5111 is perpendicular to the reciprocating motion direction on the tub wall 120, which can better drive the clothes to tumble inside the tub.

[0114] In another specific structure, the auxiliary washing protrusions can also be distributed in a dot matrix on the surface of the slide body. The shape of the auxiliary washing protrusions can be round, square, triangular, etc., which can also improve the washing performance.

[0115] Alternatively, several raised ribs or protrusions of different shapes and angles can be set on the surface of the skateboard body as auxiliary washing protrusions. The auxiliary washing protrusions of different shapes and angles can generate irregular agitation of clothes and water, thereby improving the washing effect more effectively.

[0116] Furthermore, the first assembly part 512 is a hollow rod-shaped structure, the upper end of the first elastic member 610 abuts against the fixed seat 150, and the lower end passes through the internal hollow structure of the first assembly part 512 and abuts against the slide body 511.

[0117] In the above scheme, the first elastic element 610 is disposed inside the first assembly part 512, which effectively limits the first elastic element 610 and prevents the first elastic element 610 from falling out and failing.

[0118] In one specific structure, the skateboard body 511 is spaced apart from the inner surface of the barrel wall 120, and the lower end of the first elastic member 610 is located between the skateboard body 511 and the inner surface of the barrel wall 120. The side of the skateboard body 511 facing the barrel wall 120 has a stop portion 5112 protruding towards the barrel wall 120, and the lower end of the first elastic member 610 abuts against the stop portion 5112.

[0119] As a detailed embodiment, the fixing base 150 has a stop structure inside, which abuts against the upper end of the first elastic member 610. The lower surface of the stop structure has a downwardly protruding first fixing post 151, and the upper surface of the stop part 5112 has an upwardly protruding second fixing post 5113. The first elastic member 610 is a compression spring, with its upper end fitted onto the first fixing post 151 and its lower end fitted onto the second fixing post 5113. When the washing auxiliary assembly 500 moves upward, the stop part 5112 moves closer to the stop structure inside the fixing base 150, compressing the first elastic member 610. When the washing auxiliary assembly 500 moves from the crest to the trough of the support surface 331, the first elastic member 610 gradually extends, thereby pushing the washing auxiliary assembly 500 downward with the support surface 331.

[0120] With the above structure, the upper and lower ends of the first elastic member 610 are respectively limited in the horizontal direction, which further ensures that the first elastic member 610 will not come out from between the fixed seat 150 and the washing auxiliary component 500, thereby effectively driving the washing auxiliary component 500 to descend with the support surface 331.

[0121] In a further embodiment, the washing auxiliary assembly 500 has a support member 520 disposed below the auxiliary washing slide plate 510. The support member 520 is used to contact the support member 300 and drive the washing auxiliary assembly 500 to move along the support surface 331 of the support member 300.

[0122] In a preferred embodiment, the upper end of the support member 520 is movably connected to the auxiliary washing slide plate 510, and the lower end contacts the support surface 331. A buffer member 540 is provided between the auxiliary washing slide plate 510 and the support member 520, which keeps the lower end of the support member 520 abutting against the support surface 331.

[0123] In one specific embodiment, the buffer 540 includes a second elastic member 541, through which a downward elastic force is provided to the support member 520.

[0124] Using the above solution, when the washing auxiliary component 500 moves from the crest to the trough of the support surface 331, if the auxiliary washing slide plate 510 is not pushed by the first elastic member 610 due to the influence of the clothes, the second elastic member 541 can push the support member 520 down, so that the lower end of the support member 520 always abuts against the support surface 331. This avoids the problem of the support member 520 suddenly falling and colliding with the support surface 331, thus preventing abnormal noise.

[0125] On the other hand, when the washing auxiliary component 500 moves from the trough to the crest of the support surface 331, the support component 520 moves up along the support surface 331, compressing the second elastic element 541. Then, the elastic force of the second elastic element 541 is used to push the auxiliary washing slide plate 510 to overcome the elastic force of the first elastic element 610 and move upward, making the overall movement of the washing auxiliary component 500 more gentle.

[0126] In a preferred structure, the support member 520 includes a support rod 521 and a rolling element 522. The support rod 521 is connected to the auxiliary washing slide plate 510, and the rolling element 522 is disposed at the lower end of the support rod 521 and contacts and engages with the support surface 331.

[0127] The rolling element 522 can be a roller. Through the rolling element 522's rolling contact with the support surface 331, when the washing tub 100 and the support member 300 rotate relative to each other, the rolling element 522 rolls along the support surface 331, causing the washing auxiliary component 500 to move up and down along the tub wall 120. The rolling contact between the rolling element 522 and the support surface 331 significantly reduces the friction between them, allowing the lower end of the washing auxiliary component 500 to move more smoothly along the support surface 331, and also reducing wear and noise.

[0128] In a further embodiment, the auxiliary washing slide plate 510 has a second assembly portion 513 formed by extending downward from the lower part of the slide plate body 511, for connecting the support member 520.

[0129] In one specific structure, the second assembly part 513 is a hollow rod-shaped structure, and the upper end of the support member 520, that is, the upper end of the support rod 521, is inserted into the second assembly part 513 in a way that allows it to move up and down. The second elastic member 541 is disposed inside the second assembly part 513, with its upper end abutting against the second assembly part 513 and its lower end abutting against the support member 520.

[0130] More specifically, the upper end of the second assembly part 513 has a horizontally arranged baffle 5131. The second elastic member 541 is a compression spring, the upper end of which abuts against the lower side of the baffle 5131, and the lower end abuts against the upper end face of the support rod 521.

[0131] Furthermore, a protective cover 160 is provided on the inner side of the bottom of the washing tub 100, and the lower end of the second assembly part 513 passes through the protective cover 160 and moves up and down on the lower side of the protective cover 160.

[0132] Specifically, the washing tub 100 has a bottom wall 130 and a peripheral side wall surrounding the outer periphery of the bottom wall, with the lower end of the tub wall 120 fitted onto the upper part of the peripheral side wall. A protective cover 160 is disposed inside the peripheral side wall and extends obliquely outward from bottom to top. A second mounting part 513 extends downward from the lower end of the sliding plate body 511 and passes through the upper region of the protective cover 160.

[0133] More specifically, the inner surface of the peripheral sidewall of the tub bottom 130 is partially recessed in the area where the protective cover 160 is installed. The protective cover 160 is fastened to the recessed area, and the upper end of the protective cover 160 is higher than the top of the peripheral sidewall, abutting against the inner surface of the tub wall 120. In this way, the protective cover 160 does not form an obvious protruding structure at the bottom of the washing tub 100, thus avoiding occupying the washing space inside the washing tub 100.

[0134] In one specific embodiment, the fixed base 150 is provided with a first through hole for the first assembly part 512 to pass through, and the protective cover 160 is provided with a second through hole for the second assembly part 513 to pass through. During the up-and-down movement of the auxiliary washing slide plate 510 along the tub wall 120, the first and second through holes respectively guide the first assembly part 512 and the second assembly part 513, ensuring the stability of the up-and-down movement direction of the auxiliary washing slide plate 510.

[0135] Furthermore, when the washing auxiliary assembly 500 moves to its lowest position on the washing tub 100, the upper end of the first assembly 512 is located inside the fixing base 150. When the washing auxiliary assembly 500 moves to its highest position on the washing tub 100, the lower end of the second assembly 513 is located below the protective cover 160.

[0136] In this embodiment, during the up-and-down movement of the auxiliary washing slide plate 510, the upper end of the first assembly part 512 is always located inside the fixed base 150, and the lower end of the second assembly part 513 is always located below the protective cover 160. That is to say, neither the upper end of the first assembly part 512 nor the lower end of the second assembly part 513 is directly exposed to the washing space that can contact the clothes.

[0137] In this way, the first elastic element 610 is not directly exposed inside the washing tub 100, thus preventing it from rubbing against the clothes and failing. The second assembly section 513 will not allow a large amount of water to enter, preventing lint and other debris from getting stuck on the second elastic element 541 and causing it to fail after prolonged use.

[0138] In a further embodiment, a vertically extending limiting hole 121 is provided on the tub wall 120 of the washing tub 100, and a sliding plate seat 530 located on the outer side of the tub wall 120 passes through the limiting hole 121 and is connected to the sliding plate body 511. During washing, the washing auxiliary component 500 moves up and down along the limiting hole 121 on the tub wall 120.

[0139] Specifically, in this embodiment, the limiting hole 121 is a strip-shaped hole extending a certain length along the height direction. The limiting hole 121 facilitates the connection of the washing auxiliary component 500 on both the inner and outer sides of the tub wall 120, enabling the assembly of the washing auxiliary component 500 on the tub wall 120. On the other hand, it restricts the movement trajectory of the washing auxiliary component 500, serving a limiting and guiding function.

[0140] More specifically, two parallel, circumferentially spaced limiting holes 121 are provided at the installation position of the washing auxiliary component 500. The two parallel limiting holes 121 form a group for installing the washing auxiliary component 500, resulting in a more stable structure.

[0141] In the above structure, the limiting hole 121, the fixing seat 150 and the protective cover 160 respectively play a guiding role in different areas of the auxiliary washing slide plate 510, ensuring that the movement trajectory of the auxiliary washing slide plate 510 remains stable.

[0142] In a preferred structure, the left and right edges of the limiting hole 121 have bent portions 122 extending into the washing tub 100. The bent portions 122 help to ensure the strength of the tub wall 120 in the limiting hole 121 and its outer peripheral area, thereby extending its service life.

[0143] In one specific implementation, the bent portion 122 is formed by the flanges on both sides of the limiting hole 121, which is simple to process and can effectively enhance the structural strength.

[0144] In a further embodiment, the maximum diameter of the support member 300 is less than or equal to the outer diameter of the tub bottom 130. That is, the radial dimension of the support member 300 does not exceed the outer periphery of the washing tub 100, thus not occupying the space between the washing tub 100 and the outer water tank.

[0145] In this way, it is not necessary to increase the distance between the washing tub 100 and the water tank in order to set up the support 300, thus avoiding compressing the volume of the washing tub 100, nor is it necessary to increase the overall size of the washing equipment in order to increase the diameter of the water tank.

[0146] In one specific embodiment, the support member 300 includes a connecting portion 310 for connecting the fixed shaft 433, a support portion 330 for forming a support surface 331, and a transition portion 320 for connecting the support portion 330 and the connecting portion 310. The connecting portion 310 is located in the central region below the bottom 130 of the washing tub 100 and is fitted onto the fixed shaft 433. The transition portion 320 extends from the outer periphery of the connecting portion 310 towards the outer periphery of the bottom 130, with its extended end approaching the outer periphery of the bottom 130. The support portion 330 extends upward from the extended end of the transition portion 320, and its top end forms a support surface 331 with a height variation along the circumferential direction.

[0147] In a more specific structure, the transition portion 320 extends horizontally from the outer periphery of the connecting portion 310 to the outer periphery of the bottom wall of the barrel bottom 130, and then continues to extend outward and tilt upward, thereby surrounding the periphery of the side wall of the barrel bottom 130. The support portion 330 extends vertically upward from the extended end of the transition portion 320 to form a support surface 331.

[0148] In detail, the peripheral sidewall of the barrel bottom 130 is connected to the bottom wall at an angle greater than 90°, and the portion of the transition part 320 surrounding the peripheral sidewall of the barrel bottom 130 is a curved surface structure that bulges outward, thereby matching the outer contour of the peripheral sidewall.

[0149] It should be noted that the "outer contour of the peripheral sidewall" mentioned above refers to the outer surface of the peripheral sidewall for structures with a smooth outer surface; while if the outer side of the peripheral sidewall is provided with reinforcing ribs, the outer contour refers to a virtual surface that can connect the end faces of each reinforcing rib.

[0150] In a preferred configuration, the transition portion 320 is provided with a plurality of through holes 321 to reduce the overall mass of the support member 300. Specifically, the through holes 321 are provided in the horizontally extending region of the transition portion 320, have a certain length in the radial direction, and are distributed at intervals in the circumferential direction.

[0151] The through hole 321 can effectively control the overall weight of the washing equipment and reduce the driving force required to drive the support 300 to rotate during the dehydration process.

[0152] The support member 300 in this embodiment has the above-described structure. The outer diameter of the support portion 330 constitutes the maximum diameter of the support member 300. The support surface 331 is located entirely below the bottom of the bucket 130 and does not exceed the outer periphery of the bottom of the bucket 130 in the radial direction.

[0153] Furthermore, in order to achieve contact and engagement between the lower end of the washing auxiliary component 500 and the support surface 331, a through hole 131 is provided in the outer peripheral area of ​​the tub bottom 130, and the second assembly part 513 is movably inserted into the through hole 131.

[0154] In the specific structure, the through hole 131 has a certain height along the axial direction of the washing tub 100, so that the through hole 131 can also guide the second assembly part 513. When the auxiliary washing slide plate 510 moves up and down, the lower end of the second assembly part 513 is always lower than the upper end of the through hole 131, and the second assembly part 513 will not come out of the through hole 131, thus avoiding the second assembly part 513 failing to accurately insert into the through hole 131 when the auxiliary washing slide plate 510 descends.

[0155] In the above scheme, the first through hole on the fixed seat 150, the limiting hole 121 on the tub wall 120, the second through hole on the protective cover 160, and the through hole 131 on the tub bottom 130 work together to guide the up and down movement of the washing auxiliary component 500, making the movement process more stable.

[0156] In this embodiment, two or more washing auxiliary components 500 can be arranged at intervals along the circumference of the washing tub 100, preferably evenly distributed along the circumference. Correspondingly, the number of fixing seats 150 and protective covers 160, the number of sets of limiting holes 121, and the number of through holes 131 are all consistent with the number of washing auxiliary components 500.

[0157] In the preferred configuration, two to four washing auxiliary components 500 are spaced apart along the circumference of the washing tub 100.

[0158] As a further embodiment, a lint filter can be installed inside the washing auxiliary component to expand its functionality. The lint filter can adopt the structure of a lint filter in an existing pulsator washing machine, and is disposed within the space between the slide plate body and the drum wall.

[0159] Furthermore, one or more lint filters can be installed on the area of ​​the washing tub wall where no washing auxiliary components are installed, thereby improving the lint filtration efficiency.

[0160] The washing equipment provided in this embodiment has the above-mentioned tub assembly. During the washing process, the motor 410 drives the impeller 110 and the washing tub 100 to rotate in opposite directions through the reduction clutch 430, and keeps the support 300 stationary.

[0161] At this time, the washing auxiliary component 500 rotates circumferentially with the washing tub 100, and the rolling element 522 at the lower end of the washing auxiliary component 500 rolls along the support surface 331 at the upper end of the support member 300. When the rolling element 522 rolls from the trough to the crest of the support surface 331, the support member 520 rises as a whole, compressing the second elastic element 541, which in turn pushes the auxiliary washing slide plate 510 up along the tub wall 120 and compresses the first elastic element 610. When the rolling element 522 rolls from the crest to the trough of the support surface 331, the second elastic element 541 pushes the support member 520 downward, keeping the rolling element 522 in contact with the support surface 331. At the same time, the elastic force of the first elastic element 610 pushes the auxiliary washing slide plate 510 downward, causing it to overcome the resistance of clothes and water and descend. Thus, during the washing process, the washing auxiliary component 500 rotates with the washing tub 100 and moves steadily up and down along the tub wall 120, which can come into contact with the clothes to enhance the tumbling effect of the clothes in the tub, and at the same time enhance the friction on the clothes, thereby improving the washing performance.

[0162] During the dehydration process, the motor 410 drives the impeller 110, washing tub 100 and support 300 to rotate synchronously through the reduction clutch 430. At this time, the washing auxiliary component 500 and the washing tub 100 remain relatively stationary, thus achieving the purpose of dehydrating the clothes.

[0163] The washing equipment provided in this embodiment has a simple structure and the washing auxiliary component 500 has high reliability of movement, which can improve the tumbling performance of clothes during the washing process, thereby improving the washing effect.

[0164] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
