Description

Technical Field

[0001] The present invention relates to the field of washing, and particularly provides a washing assembly and a washing apparatus.

[0002] The present application claims priority of three Chinese patent applications CN202211105453.1, CN202211105118.1 and CN202211105100.1, which are entitled "Washing Assembly and Washing Apparatus" and filed on September 9, 2022, and the entire content thereof is incorporated herein by reference as a part of the present application.

Background Art

[0003] In order to improve washing efficiency and wash different clothes separately, a washing machine provided with a "dual tub" technology can be used, that is, in order to wash different clothes, besides the original main tub, a sub tub is additionally arranged in the main tub of the washing machine. The original purpose of the "dual tub" washing machine is to save water and electricity as much as possible, but this technology still has many defects.

[0004] In order to realize complete isolation between the small tub and the inner tub, the small tub adopts a non-porous design, and when the small tub performs dewatering, water is discharged from the top edge of the small tub by means of high-speed rotation. When there are clothes in the large tub, this drainage method causes the discharged water to splash onto the clothes in the large tub, which leads to the clothes in the large tub getting wet or contaminated.

[0005] Therefore, in related fields, there is an urgent need for a washing assembly and a washing apparatus to solve the above technical problems.

[0062] Solution 1, CN202211105453.1, Example 1

[0063] The aim is to solve the problem that conventional small-tank drainage systems can lead to clothes in the large tank getting wet or contaminated.

[0064] As shown in Figures 1 to 4, this embodiment discloses a washing machine that is primarily used for washing clothes but can also be used for washing shoes and other items, specifically a pulsator-type washing machine.

[0065] Specifically, as shown in Figures 1-3, the washing machine includes a main body 01, a drive mechanism 06, and a washing assembly. Here, the washing assembly includes a large tub 02, a small tub 03, a first pulsator 04, and a second pulsator 05.

[0066] Here, the large tank 02 is rotatably mounted within the aircraft body 01, the first pulsator 04 is mounted within the large tank 02 and located at the bottom of the large tank 02, and the first pulsator 04 and the large tank 02 are arranged coaxially. The first pulsator 04 can rotate independently, thereby ensuring that the small tub 03 and the large tub 02 rotate simultaneously in opposite directions, thereby guaranteeing that the clothes in the large tub 02 are effectively washed.

[0067] The small tank 03 is located inside the large tank 02, and the first pulsator and the large tank 02 are arranged coaxially. By mounting the small tank 03 on the first pulsator 04, the first pulsator 04 can synchronously rotate the small tank 03. Specifically, the small tub 03 and the first pulsator 04 are detachably engaged. In this embodiment, the small tub 03 and the first pulsator 04 are quickly and detachably connected, so that when clothes are washed only in the large tub 02 and the small tub 03 is not needed, the small tub 03 can be quickly removed, and when it is necessary to wash clothes in the small tub 03, the small tub 03 can be quickly attached to the first pulsator 04.

[0068] The second pulsator 05 is provided inside the small tank 03 and is located at the bottom of the small tank 03, and the second pulsator 05 and the small tank 03 are arranged coaxially. The second pulsator 05 can rotate independently, thereby ensuring that the second pulsator 05 and the small tub 03 rotate simultaneously in opposite directions, thereby guaranteeing that the clothes in the small tub 03 are effectively washed. Specifically, the first pulsator 04 is a large pulsator, and the second pulsator 05 is a small pulsator. The first pulsator 04 rotates to wash the clothes in the large tub 02, and the second pulsator 05 rotates to wash the clothes in the small tub 03.

[0069] The large tank 02, the first pulsator 04, and the second pulsator 05 are specifically rotationally driven by a drive mechanism 06. The drive mechanism 06 is located inside the machine body 01 and is positioned at the bottom of the first pulsator 04, and the large tank 02, the first pulsator 04, and the second pulsator 05 are all powered by the drive mechanism 06. The drive mechanism 06 includes a drive motor and a clutch provided at the output terminal of the drive motor. The large tank 02, the first pulsator 04, and the second pulsator 05 are each connected to different output terminals of the clutch. This allows the drive motor to rotate the large tank 02, the first pulsator 04, and the second pulsator 05 simultaneously or separately, and at the same time, to control the rotation of the large tank 02, the first pulsator 04, and the second pulsator 05, and also to control the operation of one, two, or three of the three separately. Specifically, the clutch is provided with a first output shaft, a second output shaft, and a third output shaft, where the second output shaft is fitted to the first output shaft and rotatable relative to the first output shaft, and the third output shaft is fitted to the second output shaft and rotatable relative to the second output shaft. By fixing the first output shaft to the second pulsator 05, the drive mechanism 06 can rotate the second pulsator 05 via the first output shaft. By fixing the second output shaft to the first pulsator 04, the drive mechanism 06 can rotate the first pulsator 04 via the second output shaft. By fixing the third output shaft to the large tank 02, the drive mechanism 06 can rotate the large tank 02 via the third output shaft.

[0070] The space between the large tub 02 and the small tub 03 is the first washing cavity 021, and the space inside the small tub 03 is the second washing cavity 031.

[0071] Since the large tub 02, the first pulsator 04, and the second pulsator 05 can each rotate in different directions and their rotation can be controlled individually, the first washing cavity 021 and the second washing cavity 031 can be used simultaneously, or either one can be used individually. When there is a relatively small amount of clothing, it can be washed using only the second washing cavity 031; when there is a slightly larger amount of clothing, it can be washed using only the first washing cavity 021; and when there is a relatively large amount of clothing, it can be washed simultaneously in both the first washing cavity 021 and the second washing cavity 031. Of course, the first washing cavity 021 and the second washing cavity 031 may also be used to wash different types of clothing. For example, the first washing cavity 021 is used to wash regular jackets and the second washing cavity 031 is used to wash underwear, or the first washing cavity 021 is used to wash regular clothes and the second washing cavity 031 is used to wash socks, etc.

[0072] Referring again to Figures 2 and 3, the arrows in Figure 2 indicate the water flow path within the small tank 03. A drainage channel 032 is provided along the length of the side wall of the small tank 03, and the water inlet of the drainage channel 032 is located at the top of the wall of the small tank 03. A drainage hole 041 is provided at the bottom of the first pulsator 04, and the drainage channel 032 communicates with the drainage hole 041. As specifically shown by the arrows in Figure 2, when the small tank 03 rotates, the water in the small tank 03 flows into the drainage channel 032 due to the action of centrifugal force, is then discharged to the bottom of the first pulsator 04 through the drainage hole 041, and subsequently discharged from the drainage pipe under the machine body 01. During drainage, water does not flow into the large tank 02, ensuring that the water discharged from the small tank 03 does not splash onto the clothes in the large tank 02, thus ensuring that the clothes in the large tank 02 do not get wet and that the large tank 02 and the clothes inside it do not become contaminated.

[0073] The small tank 03 is a conical cylinder, and the inner diameter of the top of the small tank 03 is larger than the inner diameter of the bottom. By designing the tank to be conical, the small tank 03 can throw the water inside it to the top at a relatively low rotational speed and into the drainage channel 032, thereby ensuring that the clothes inside the small tank 03 are not easily thrown out.

[0074] Specifically, in this embodiment, the drain channel 032 protrudes both inward and outward from the side wall of the small tank 03. Because the drain channel 032 is vertically arranged and is a pipe of equal diameter, the outward protrusion increases as you go down, with the top hardly protruding outward at all, while the inward protrusion increases as you go up, with the top almost completely protruding inward, and the bottom hardly protruding inward at all. By integrally molding the drain channel 032 and the small tank 03, the structural strength of the drain channel 032 and the small tank 03 can be ensured. In other embodiments, the drain channel 032 may be provided so as to protrude inward only from the inner wall of the small tank 03, or it may be provided so as to protrude outward only from the outer wall of the small tank 03.

[0075] The drain hole 041 is located below the drain channel 032, specifically directly below the drain channel 032, but it may also be located to the side or below. Since a drain hole 041 with a larger opening is provided directly below the drain channel 032, the water in the drain channel 032 can be quickly discharged below the first pulsator 04 and then discharged from the drain pipe below the machine body 01. In other embodiments, a plurality of drainage holes 041 with smaller openings may be provided below the drainage channel 032. In this arrangement, the drainage speed is slightly slower, but the structural strength of the first pulsator 04 can be effectively ensured.

[0076] The first pulsator 04 is provided with an insertion port, and the drainage channel 032 is inserted into the insertion port. Specifically, as shown in Figures 3 and 4, a convex rib 042 is arranged around the drain hole 041 of the first pulsator 04, and the convex rib 042 surrounds and forms an insertion opening. A groove is provided at the bottom of the drain channel 032, which is located inside the small tank, and after the small tank 03 is installed, the portion of the convex rib 042 located outside the small tank 03 is exposed, and the portion located inside the small tank 03 is embedded in the groove.

[0077] Furthermore, regarding the arrangement of the drainage hole 041, providing the drainage hole 041 below the drainage channel 032 does not limit the present invention. Without departing from the principles of the present invention, those skilled in the art may employ other arrangements in other embodiments, as long as they are in communication with the drainage channel 032 and can drain the water in the drainage channel 032 to the bottom of the first pulsator 04. For example, the first pulsator 04 is provided with water-repellent ribs, and a drainage cavity is provided horizontally inside the water-repellent ribs. The drain hole 041 is provided in the bottom wall of the drain cavity, and a communication port is provided in the outer wall of the small tank 03, thereby connecting the drain channel 032 to the drain cavity, allowing water in the drain channel 032 to flow into the drain cavity, and further flow through the drain cavity to the drain hole 041, where it is discharged below the first pulsator 04. Finally, it is discharged from the drain pipe at the bottom of the machine body 01. Since these do not all deviate from the fundamental principles of the present invention, they are included within the scope of protection of the present invention.

[0078] Since two drainage channels 032 are symmetrically arranged along the circumferential direction on the side wall of the small tank 03, it is possible to ensure that water in the small tank 03 is quickly drained without having to install more drainage channels 032, thereby simplifying the overall structure and saving on manufacturing difficulties and costs.

[0079] Regarding the number of drainage channels 032, providing two is not a limitation of the present invention. More drainage channels may be provided without departing from the principles of the present invention. Specifically, multiple drainage channels 032 may be provided at intervals along the circumferential direction of the side wall of the small tank 03. Specifically, there may be three, four, or five channels. Since none of these deviate from the basic principles of the present invention, they are all within the scope of protection of the present invention.

[0080] Solution 2, CN202211105118.1, Example 2

[0081] The present invention aims to solve the problem of the inconvenience of attaching and detaching the smaller tub in conventional double-tub washing machines.

[0082] As shown in Figures 5 to 12, this embodiment discloses a washing machine that is primarily used for washing clothes but can also be used for washing shoes and other items, specifically a pulsator-type washing machine.

[0083] The washing machine includes a main unit 01, a drive mechanism 06, and a washing assembly. Here, the washing assembly includes a large tub 02, a small tub 03, a first pulsator 04, a second pulsator 05, an engagement block 033, a drive block 034, an elastic member 037, and a fixing block 041.

[0084] As shown in Figure 5, the large tank 02 is rotatably mounted within the machine body 01, the first pulsator 04 is mounted within the large tank 02 and located at the bottom of the large tank 02, and the first pulsator 04 and the large tank 02 are arranged coaxially. The first pulsator 04 can rotate independently, thereby ensuring that the small tub 03 and the large tub 02 rotate simultaneously in opposite directions, thereby guaranteeing that the clothes in the large tub 02 are effectively washed.

[0085] The small tank 03 is located within the large tank 02 and is arranged coaxially with the first pulsator and the large tank 02. By mounting the small tank 03 on the first pulsator 04, the first pulsator 04 can synchronously rotate the small tank 03. A drainage channel 032 is provided along the length of the side wall of the small tank 03, and a drainage hole corresponding to the drainage channel 032 is provided in the first pulsator 04, with the drainage hole located directly below the drainage channel 032. There are two drainage channels 032, and they are arranged symmetrically on the small tank 03. The small tank 03 is a conical cylinder, with an inner diameter at the top greater than the inner diameter at the bottom. As the small tank 03 rotates, the water inside it moves to the top, then flows downward along the drain channel 032, and finally flows below the first pulsator 04 through the drain hole, so that the water inside the small tank 03 does not come into contact with the inner wall of the large tank 02 or the clothes inside the large tank 02.

[0086] As shown in Figures 6-10, the small tank 03 and the first pulsator 04 are specifically detachably engaged. In this embodiment, the small tub 03 and the first pulsator 04 are connected in a quick and detachable manner. When clothes are washed only in the large tub 02 and the small tub 03 is not needed, the small tub 03 can be quickly removed. When it is necessary to wash clothes in the small tub 03, the small tub 03 can be quickly attached to the first pulsator 04.

[0087] Specifically, the engaging block 033 is slidably mounted at the bottom of the small tank 03, and the first pulsator 04 is provided with a position limiting groove 0411. The engaging block 033 extends at least partially into the position limiting groove 0411 to limit and fix the position of the small groove 03, and when the engaging block 033 disengages from the position limiting groove 0411, the position limiting and fixing to the small groove 03 can be released, thereby making it easier to remove the small groove 03 from the first pulsator 04. Specifically, the engaging block 033 is moved to partially extend into the position limiting groove 0411, thereby limiting and fixing the position of the small tank 03, completing the installation of the small tank 03. The installation method is simple and quick. By moving the engaging block 033 to detach from the position limiting groove 0411, the position limiting and fixing to the small tank 03 are released, and the small tank 03 can be removed. The removal method is simple and quick. In other words, attaching and detaching the small tank 03 of the present invention is relatively simple, quick, and efficient.

[0088] Specifically, the end of the engagement block 033 extends into the position limiting groove 0411, thereby limiting and fixing the position of the small groove 03. A mounting groove is provided at the bottom of the small tank 03, and the engaging block 033 is slidably mounted within the mounting groove. The mounting groove is provided facing outward from the small tank 03, and the longitudinal extension of the mounting groove can extend to the central axis of the small tank 03. The elastic member 037 is provided within the mounting groove, and both ends of the elastic member 037 act on the bottom of the mounting groove and the engagement block 033, respectively. The elastic member 037 drives the engagement block 033, causing it to partially extend within the position limiting groove 0411. Specifically, the elastic member 037 is a compression spring, and a connecting column 0332 is provided at the end of the engagement block 033. The spring is fitted into the connecting column, and the connecting column 0332 restricts the position of the spring, thereby ensuring the stability of the spring. This allows the spring to effectively slide on the engagement block 033 and partially extend into the position limiting groove 0411. Due to the action of the elastic member 037, the end of the engagement block 033 that is away from the elastic member 037 can always remain extended within the position limiting groove 0411. In other embodiments, the elastic member 037 may be a rubber spring or an air spring, as long as the end of the engagement block 033 can extend into the position limiting groove 0411.

[0089] The engaging block 033 is provided with a housing groove 0331 located in the middle portion of the engaging block 033, and the drive block 034 is provided within the housing groove 0331. The drive block 034 is provided with an upward-facing first inclined surface 0341, and the engagement block 033 is provided with a downward-facing second inclined surface 0333. The second inclined surface 0333 is located at the end closest to the elastic member 037, that is, at the end furthest from the position limiting groove 0411, and the first inclined surface 0341 and the second inclined surface 0333 are in close contact with each other. When the drive block 034 moves upward, the first inclined surface 0341 moves upward and slides against the second inclined surface 0333, driving the engagement block 033 away from the position limiting groove 0411, thereby disengaging the engagement block 033 from the position limiting groove 0411.

[0090] A housing hole 038 is provided in the side wall of the small tank 03, and a connecting rod 035 is connected to the drive block 034. The connecting rod 035 passes through the housing hole 038 and extends upward from the small tank 03. When the connecting rod 035 is pulled upward, the drive block 034 can be moved upward, thereby driving the engaging block 033 to disengage from the position limiting groove 0411. After the connecting rod 035 is pushed downward, the engaging block 033 is no longer limited in position, and due to the action of the elastic member 037, the engaging block 033 is driven toward one end of the position limiting groove 0411, causing the engaging block 033 to partially extend within the position limiting groove 0411.

[0091] Preferably, in this embodiment, there are two connection positions where the small tank 03 and the first pulsator 04 engage, and these are arranged symmetrically. In other words, the number of engaging blocks 033, elastic members 037, and fixing blocks 041 are all two. In other embodiments, those skilled in the art may select multiple connection positions depending on the connection requirements, and the multiple connection positions may be spaced apart along the circumferential direction of the small tank 03.

[0092] As shown in Figures 9-12, the washing assembly further includes a handle 036 pivotably connected to the top of the small tub 03, the handle 036 being connected to the top of a connecting rod 035, and pulling the handle 036 upwards allows the connecting rod 035 to move upwards. Specifically, the handle 036 is provided with a connecting pin 0361, and since the connecting pin 0361 is located above the pivot connection between the small tank 03 and the handle 036, when the handle 036 is pulled upward, the connecting pin 0361 can move in an arc. An elongated hole 0351 is provided horizontally at the top of the connecting rod 035, and a connecting pin 0361 is drilled into the elongated hole 0351. When the handle 036 is pulled upward, the connecting pin 0361 moves in an arc and horizontally relative to the elongated hole 0351, thereby moving the connecting rod 035 vertically upward. This moves the drive block 034 upward, driving the engagement block 033 to disengage from the position limiting groove 0411. The elongated hole 0351 is provided to ensure that the connecting rod 035 always moves vertically without tilting, thereby ensuring the stability of the connection between the connecting rod 035 and the drive block 034 and preventing damage to the connection between the connecting rod 035 and the drive block 034.

[0093] As shown in Figures 6-10, the fixed block 041 is fixed to the first pulsator 04, the two are fixed together with screws, and a position limiting groove 0411 is provided in the fixed block 041. To facilitate installation, the bottom of one end of the engaging block 033 closest to the fixing block 041 is made into an inclined surface, and the upper edge of the fixing block 041 is also chamfered, allowing the engaging block 033 to be compressed and installed more effectively.

[0094] The fixed block 041 is provided with an observation window that allows observation of the inside of the position limiting groove 0411. Through the observation window 0412, it is possible to observe whether the engaging block 033 extends into the position limiting groove 0411 and to determine whether the small groove 03 is installed in the predetermined position. Specifically, if the engagement block 033 is visible from the observation window 0412, it means that the engagement block 033 extends into the position limiting groove 0411. In this case, the engagement block 033 can limit and fix the position of the small groove 03, indicating that the small groove 03 is installed in the predetermined position. If the engagement block 033 is not visible from the observation window 0412, it means that the engagement block 033 does not extend into the position limiting groove 0411 and cannot limit and fix the position of the small groove 03, indicating that the small groove 03 is not installed in the predetermined position. The observation window 0412 allows for determination of whether or not the small tub 03 is installed in the designated position. The observation method is simple, and the structure of the observation window 0412 is also simple, resulting in a simpler laundry assembly structure and lower costs.

[0095] To facilitate observation and judgment, the engaging block 033 and the fixed block 041 are of different colors. The first pulsator 04 and the fixed block 041 are typically light colors such as white or gray, while the ends of the engaging block 033 that extend within the position limiting groove 0411 are red, blue, or green. Preferably, the engagement block 033 is entirely red and has a bright color, making it easy to observe whether the end of the engagement block 033 extends into the position limiting groove 0411.

[0096] Continuing to refer to Figure 5, the second pulsator 05 is provided inside the small tub 03 and is located at the bottom of the small tub 03, and the second pulsator 05 and the small tub 03 are arranged coaxially. The second pulsator 05 can rotate independently, thereby ensuring that the second pulsator 05 and the small tub 03 rotate simultaneously in opposite directions, thereby ensuring that the clothes in the small tub 03 are effectively washed. Specifically, the first pulsator 04 is a large pulsator, and the second pulsator 05 is a small pulsator. The first pulsator 04 rotates to wash the clothes in the large tub 02, and the second pulsator 05 rotates to wash the clothes in the small tub 03.

[0097] The large tank 02, the first pulsator 04, and the second pulsator 05 are specifically rotated by the drive mechanism 06. The drive mechanism 06 is located inside the machine body 01 and at the bottom of the first pulsator 04, and the large tank 02, the first pulsator 04, and the second pulsator 05 are all power-driven to the drive mechanism 06. The drive mechanism 06 includes a drive motor and a clutch provided at the output end of the drive motor. The large tank 02, the first pulsator 04, and the second pulsator 05 are each connected to different output terminals of the clutch. This allows the drive motor to rotate the large tank 02, the first pulsator 04, and the second pulsator 05 simultaneously or separately, and at the same time, to control the rotation of the large tank 02, the first pulsator 04, and the second pulsator 05, and also to control the operation of one, two, or three of the three separately. Specifically, the clutch is provided with a first output shaft, a second output shaft, and a third output shaft. The second output shaft is fitted onto the first output shaft and is rotatable relative to the first output shaft, and the third output shaft is fitted onto the second output shaft and is rotatable relative to the second output shaft. The second pulsator 05 is fitted onto the first output shaft, the fitting hole of the second pulsator 05 is a square hole, and the top end of the first output shaft is a square shaft. The drive mechanism 06 can rotate the second pulsator 05 via the first output shaft. By fixing the second output shaft to the first pulsator 04, the drive mechanism 06 can rotate the first pulsator 04 via the second output shaft. By fixing the third output shaft to the large tank 02, the drive mechanism 06 can rotate the large tank 02 via the third output shaft.

[0098] The small tank 03 is a tank with a bottom, and the second pulsator 05 is located inside the small tank 03 and is rotatably connected to the small tank 03 via bearings. When removing the small tank 03, the second pulsator 05 is pulled out from the first output shaft to complete the removal of the second pulsator 05.

[0099] The space between the large tub 02 and the small tub 03 is the first washing cavity 021, and the space inside the small tub 03 is the second washing cavity 031.

[0100] Since the large tub 02, the first pulsator 04, and the second pulsator 05 can each rotate in different directions and their rotation can be controlled individually, the first washing cavity 021 and the second washing cavity 031 can be used simultaneously, or either one can be used individually. When there is a relatively small amount of clothing, it can be washed using only the second washing cavity 031; when there is a slightly larger amount of clothing, it can be washed using only the first washing cavity 021; and when there is a relatively large amount of clothing, it can be washed simultaneously in both the first washing cavity 021 and the second washing cavity 031. Of course, the first washing cavity 021 and the second washing cavity 031 may also be used to wash different types of clothing. For example, the first washing cavity 021 may be used to wash regular jackets and the second washing cavity 031 may be used to wash underwear, or the first washing cavity 021 may be used to wash regular clothes and the second washing cavity 031 may be used to wash socks, etc.

[0101] Solution 3, CN202211105100.1, Example 3

[0102] The aim is to solve the problem in conventional double-tub washing machines where it is not possible to determine whether the smaller tub is installed in the designated position.

[0103] As shown in Figures 5 to 12, this embodiment discloses a washing machine that is primarily used for washing clothes but can also be used for washing shoes and other items, specifically a pulsator-type washing machine.

[0104] The washing machine includes a main unit 01, a drive mechanism 06, and a washing assembly. Here, the washing assembly includes a large tub 02, a small tub 03, a first pulsator 04, a second pulsator 05, an engagement block 033, a drive block 034, an elastic member 037, and a fixing block 041.

[0105] As shown in Figure 5, the large tank 02 is rotatably mounted within the machine body 01, and the first pulsator 04 is mounted within the large tank 02 and at the bottom of the large tank 02, with the first pulsator 04 and the large tank 02 being coaxially arranged. The first pulsator 04 can rotate independently, thereby ensuring that the small tank 03 and the large tank 02 rotate simultaneously in opposite directions, thereby ensuring that the clothes in the large tank 02 are effectively washed.

[0106] The small tank 03 is located within the large tank 02 and is arranged coaxially with the first pulsator and the large tank 02. By mounting the small tank 03 on the first pulsator 04, the first pulsator 04 can synchronously rotate the small tank 03. A drainage channel 032 is provided along the length of the side wall of the small tank 03, and a drainage hole corresponding to the drainage channel 032 is provided in the first pulsator 04, with the drainage hole located directly below the drainage channel 032. There are two drainage channels 032, arranged symmetrically on the small tank 03. The small tank 03 is a conical cylinder, with the inner diameter at the top being larger than the inner diameter at the bottom. As the small tank 03 rotates, the water inside the small tank 03 moves to the top, then flows downward along the drain channel 032, and finally flows below the first pulsator 04 through the drain hole, so that the water inside the small tank 03 does not come into contact with the inner wall of the large tank 02 or the clothes inside the large tank 02.

[0107] As shown in Figures 6-10, the small tub 03 and the first pulsator 04 are detachably engaged. In this embodiment, the small tub 03 and the first pulsator 04 are quickly and detachably connected, so that when clothes are washed only in the large tub 02 and the small tub 03 is not needed, the small tub 03 can be quickly removed, and when it is necessary to wash clothes in the small tub 03, the small tub 03 can be quickly attached to the first pulsator 04.

[0108] Specifically, a position-restricting groove 0411 is provided on one of the bottoms of the first pulsator 04 and the small tank 03, and a movable engagement block 033 is provided on the other. The second pulsator 0 is provided with an observation window 0412 that allows observation of the position of the engagement block 033. The engagement block 033 extends at least partially into the position limiting groove 0411 to limit and fix the position of the small groove 03, and the position limiting and fixing of the small groove 03 can be released by the engagement block 033 disengaging from the position limiting groove 0411. Through the observation window 0412, it is possible to observe whether the engagement block 033 extends into the position limiting groove 0411, and to determine whether the small groove 03 is installed in the predetermined position.

[0109] Preferably, the engagement block 033 is movably provided at the bottom of the small tank 03, and the first pulsator 04 is provided with a position limiting groove 0411. The engaging block 033 extends at least partially into the position limiting groove 0411 to limit and fix the position of the small groove 03, and when the engaging block 033 disengages from the position limiting groove 0411, the position limiting and fixing to the small groove 03 can be released, thereby making it easier to remove the small groove 03 from the first pulsator 04. Specifically, the engagement block 033 is moved to partially extend into the position limiting groove 0411, thereby limiting and fixing the position of the small tank 03, thus completing the installation of the small tank 03. The installation method is simple and quick. The engagement block 033 can be moved to detach from the position limiting groove 0411, thereby releasing the position limiting and fixing to the small tank 03, and the small tank 03 can be removed. The removal method is simple and quick. In other words, attaching and detaching the small tank 03 of the present invention is relatively simple, quick, and efficient.

[0110] Specifically, the end of the engagement block 033 extends into the position limiting groove 0411, thereby limiting and fixing the position of the small groove 03. A mounting groove is provided at the bottom of the small tank 03, and the engaging block 033 is slidably mounted within the mounting groove. The mounting groove is provided facing outward from the small tank 03, and the longitudinal extension of the mounting groove can extend to the central axis of the small tank 03. The elastic member 037 is provided in the mounting groove, and both ends of the elastic member 037 act on the bottom of the mounting groove and the engagement block 033, respectively, so that the elastic member 037 drives the engagement block 033 and causes it to partially extend into the position limiting groove 0411. Specifically the elastic member 037 is a compression spring, and a connecting column 0332 is provided at the end of the engagement block 033, and the connecting column 0332 ensures the stability of the spring by limiting its position, so that the spring can effectively slide on the engagement block 033 and partially extend into the position limiting groove 0411. Due to the action of the elastic member 037, the end of the engagement block 033 that is away from the elastic member 037 can always be kept in a state where it extends within the position limiting groove 0411. In other embodiments, the elastic member 037 may be a rubber spring or an air spring, as long as it can keep the end of the engagement block 033 in the position limiting groove 0411.

[0111] The engaging block 033 is provided with a housing groove 0331 located in the middle portion of the engaging block 033, and the drive block 034 is provided within the housing groove 0331. The drive block 034 is provided with an upward-facing first inclined surface 0341, and the engagement block 033 is provided with a downward-facing second inclined surface 0333. The second inclined surface 0333 is located at the end closest to the elastic member 037, that is, at the end furthest from the position limiting groove 0411, and the first inclined surface 0341 and the second inclined surface 0333 are in close contact with each other. When the drive block 034 moves upward, the first inclined surface 0341 moves in the direction and slides against the second inclined surface 0333, driving the engagement block 033 away from the position limiting groove 0411, thereby disengaging the engagement block 033 from the position limiting groove 0411.

[0112] A receiving hole 0388 is provided in the side wall of the small tank 03, and a connecting rod 035 is connected to the drive block 034. The connecting rod 035 passes through the receiving hole 0388 and extends upward from the small tank 03. When the connecting rod 035 is pulled upward, the drive block 034 is moved upward, driving the engaging block 033 to disengage from the position limiting groove 0411. After the connecting rod 035 is pushed downward, the engaging block 033 is no longer limited in position, and due to the action of the elastic member 037, the engaging block 033 is driven toward one end of the position limiting groove 0411, allowing the engaging block 033 to partially extend within the position limiting groove 0411.

[0113] Preferably, in this embodiment, there are two connection positions where the small tank 03 and the first pulsator 04 engage, and these are arranged symmetrically. In other words, the number of engaging blocks 033, the number of elastic members 037, and the number of fixing blocks 041 are all 2. In other embodiments, those skilled in the art may select multiple connection positions depending on the connection requirements, and the multiple connection positions may be spaced apart along the circumferential direction of the small tank 03.

[0114] As shown in Figures 9-12, the washing assembly further includes a handle 036 pivotably connected to the top of the small tub 03, the handle 036 being connected to the top of a connecting rod 035, and pulling the handle 036 upwards allows the connecting rod 035 to move upwards. Specifically, the handle 036 is provided with a connecting pin 0361, and since the connecting pin 0361 is located above the pivot connection between the small tank 03 and the handle 036, when the handle 036 is pulled upward, the connecting pin 0361 can move in an arc. A horizontally elongated hole 0351 is provided at the top of the connecting rod 035, and a connecting pin 0361 is drilled into the elongated hole 0351. When the handle 036 is pulled upward, the connecting pin 0361 moves in an arc and horizontally relative to the elongated hole 0351, thereby moving the connecting rod 035 vertically upward. This moves the drive block 034 upward, driving the engagement block 033 to disengage from the position limiting groove 0411. The elongated hole 0351 is provided to ensure that the connecting rod 035 always moves vertically without tilting, thereby ensuring the stability of the connection between the connecting rod 035 and the drive block 034 and preventing damage to the connection between the connecting rod 035 and the drive block 034.

[0115] As shown in Figures 6-10, the fixed block 041 is fixed to the first pulsator 04, and the two are fixed together with screws, and a position limiting groove 0411 is provided in the fixed block 041. To facilitate installation, the bottom of one end of the engaging block 033 closest to the fixed block 041 is made into an inclined surface, and the upper edge of the fixed block 041 is also chamfered, so that the engaging block 033 can be compressed and installed more effectively.

[0116] The observation window 0412 is provided on the fixed block 041 and specifically observes the situation inside the position limiting groove 0411, that is, whether or not the engaging block 033 extends into the position limiting groove 0411. By observing whether or not the engaging block 033 extends into the position limiting groove 0411 through the observation window 0412, it is possible to determine whether or not the small groove 03 is installed in the predetermined position. Specifically, if the engagement block 033 is visible from the observation window 0412, it means that the engagement block 033 extends into the position limiting groove 0411. In this case, the engagement block 033 can limit and fix the position of the small groove 03, indicating that the small groove 03 is installed in the predetermined position. If the engagement block 033 is not visible from the observation window 0412, it means that the engagement block 033 does not extend into the position limiting groove 0411 and cannot limit and fix the position of the small groove 03, indicating that the small groove 03 is not installed in the predetermined position. The observation window 0412 allows for determination of whether or not the small tub 03 is installed in the designated position. The observation method is simple, and the structure of the observation window 0412 is also simple, resulting in a simpler laundry assembly structure and lower costs.

[0117] To facilitate observation and judgment, the engaging block 033 and the fixed block 041 are of different colors. The first pulsator 04 and the fixed block 041 are typically light colors such as white or gray, while the portion of the engaging block 033 that extends into the position limiting groove 0411 is red, blue, or green. Preferably, the engaging block 033 is entirely red and light in color, making it easy to observe whether the portion of the engaging block 033 extends into the position limiting groove 0411.

[0118] Continuing to refer to Figure 5, the second pulsator 05 is provided inside the small tub 03 and is located at the bottom of the small tub 03, and the second pulsator 05 and the small tub 03 are arranged coaxially. The second pulsator 05 can rotate independently, thereby ensuring that the second pulsator 05 and the small tub 03 rotate simultaneously in opposite directions, thereby ensuring that the clothes in the small tub 03 are effectively washed. Specifically, the first pulsator 04 is a large pulsator, and the second pulsator 05 is a small pulsator. The first pulsator 04 rotates to wash the clothes in the large tub 02, and the second pulsator 05 rotates to wash the clothes in the small tub 03.

[0119] The large tank 02, the first pulsator 04, and the second pulsator 05 are specifically rotated by the drive mechanism 06. The drive mechanism 06 is located inside the machine body 01 and at the bottom of the first pulsator 04, and the large tank 02, the first pulsator 04, and the second pulsator 05 are all connected to the drive mechanism 06. The drive mechanism 06 includes a drive motor and a clutch provided at the output terminal of the drive motor. The large tank 02, the first pulsator 04, and the second pulsator 05 are each connected to different output terminals of the clutch. This allows the drive motor to rotate the large tank 02, the first pulsator 04, and the second pulsator 05 simultaneously or separately, to drive the rotation of the large tank 02, the first pulsator 04, and the second pulsator 05 at the same time, and to control the operation of one, two, or three of the three separately. Specifically, the clutch is provided with a first output shaft, a second output shaft, and a third output shaft. The second output shaft is fitted onto the first output shaft and is rotatable relative to the first output shaft, and the third output shaft is fitted onto the second output shaft and is rotatable relative to the second output shaft. The second pulsator 05 is fitted onto the first output shaft, the fitting hole of the second pulsator 05 is a square hole, and the top end of the first output shaft is a square shaft. The drive mechanism 06 can rotate the second pulsator 05 via the first output shaft. By fixing the second output shaft to the first pulsator 04, the drive mechanism 06 can rotate the first pulsator 04 via the second output shaft. By fixing the third output shaft to the large tank 02, the drive mechanism 06 can rotate the large tank 02 via the third output shaft.

[0120] The small tank 03 is a tank with a bottom, and the second pulsator 05 is located inside the small tank 03 and is rotatably connected to the small tank 03 via bearings. When removing the small tank 03, the second pulsator 05 is pulled out from the first output shaft to complete the removal of the second pulsator 05.

[0121] The space between the large tub 02 and the small tub 03 is the first washing cavity 021, and the space inside the small tub 03 is the second washing cavity 031.

[0122] Since the large tub 02, the first pulsator 04, and the second pulsator 05 can each rotate in different directions and their rotation can be controlled individually, the first washing cavity 021 and the second washing cavity 031 can be used simultaneously, or either one can be used individually. When there is a relatively small amount of clothing, it can be washed using only the second washing cavity 031; when there is a slightly larger amount of clothing, it can be washed using only the first washing cavity 021; and when there is a relatively large amount of clothing, it can be washed simultaneously in both the first washing cavity 021 and the second washing cavity 031. Of course, the first washing cavity 021 and the second washing cavity 031 may also be used to wash different types of clothing. For example, the first washing cavity 021 is used to wash regular jackets and the second washing cavity 031 is used to wash underwear, or the first washing cavity 021 is used to wash regular clothes and the second washing cavity 031 is used to wash socks, etc.
