[Background technology]

[0003] To increase washing efficiency and wash different clothes separately, washing machines with "dual tub" technology can be used, that is, in addition to the original main tub, the washing machine has an additional sub-tub within the main tub for washing different clothes. The purpose of the "dual tub" washing machine is to save as much water and electricity as possible, but this technology still has many flaws.

[0004] To achieve complete isolation between the small tank and the inner tank, the small tank is designed without holes, and when the small tank is dewatered, the water is discharged from the top edge of the small tank by high speed rotation. If there are clothes in the large tub, this draining method may cause the drained water to splash onto the clothes in the large tub, resulting in the clothes in the large tub becoming wet or contaminated.

[0005] Therefore, there is an urgent need in the related field for a washing assembly and washing machine that can solve the above technical problems. Summary of the Invention [Problem to be solved by the invention]

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

[0063] To solve the problem that the conventional drainage method of the small tub leads to the clothes in the large tub getting wet or soiled.

[0064] As shown in Figs. 1 to 4, this embodiment discloses a washing machine, specifically a pulsator type washing machine, which is mainly used for washing clothes but can also be used for washing shoes and the like.

[0065] 1 to 3, the washing machine includes a 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 tub 02 is rotatably arranged within the body 01, the first pulsator 04 is arranged within the large tub 02 and is located at the bottom of the large tub 02, and the first pulsator 04 and the large tub 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 ensuring that the clothes in the large tub 02 are washed effectively.

[0067] The small tank 03 is provided in the large tank 02, and the first pulsator and the large tank 02 are arranged coaxially. The small tank 03 is attached to the first pulsator 04, so that the first pulsator 04 can rotate and drive the small tank 03 in synchronization. Specifically, the small tub 03 and the first pulsator 04 are removably engaged. In this embodiment, the small tub 03 and the first pulsator 04 are quickly and detachably connected, so that when clothes are washed using only the large tub 02 and the small tub 03 is not needed, the small tub 03 can be quickly removed, and when clothes need to be washed using the small tub 03, the small tub 03 can be quickly attached to the first pulsator 04.

[0068] The second pulsator 05 is provided in 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 to ensure that the clothes in the small tub 03 are washed effectively. 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] Specifically, the large tub 02, the first pulsator 04, and the second pulsator 05 are rotationally driven by a drive mechanism 06. The drive mechanism 06 is provided inside the machine body 01 and is located at the bottom of the first pulsator 04, and the large tub 02, the first pulsator 04, and the second pulsator 05 are all connected to the drive mechanism 06 via power transmission. The drive mechanism 06 includes a drive motor and a clutch provided at the output end of the drive motor. The large tub 02, the first pulsator 04, and the second pulsator 05 are each connected to different output terminals of the clutch, so that the drive motor can drive the large tub 02, the first pulsator 04, and the second pulsator 05 to rotate simultaneously or separately, and can also control the rotation of the large tub 02, the first pulsator 04, and the second pulsator 05, and can also 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, wherein the second output shaft is fitted to the first output shaft and is rotatable relative to the first output shaft, and the third output shaft is fitted to the second output shaft and is rotatable relative to the second output shaft. The first output shaft is fixedly connected to the second pulsator 05, so that the drive mechanism 06 can drive the second pulsator 05 to rotate via the first output shaft. The second output shaft is fixedly connected to the first pulsator 04, so that the drive mechanism 06 can drive the first pulsator 04 to rotate via the second output shaft. The third output shaft is fixedly connected to the large tank 02, so that the drive mechanism 06 can drive the large tank 02 to rotate via the third output shaft.

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

[0071] The large tub 02, the first pulsator 04, and the second pulsator 05 can rotate in different directions, and whether they rotate or not can be controlled individually, so the first washing cavity 021 and the second washing cavity 031 can be used simultaneously, or either one can be used individually. If the number of clothes is relatively small, the clothes can be washed in only the second washing cavity 031; if the number of clothes is slightly large, the clothes can be washed in only the first washing cavity 021; if the number of clothes is relatively large, the clothes can be washed in both the first washing cavity 021 and the second washing cavity 031 at the same time. Of course, the first washing cavity 021 and the second washing cavity 031 may also be used to wash different types of clothes. For example, the first washing cavity 021 is used to wash regular outerwear and the second washing cavity 031 is used to wash underwear, or alternatively, the first washing cavity 021 is used to wash regular clothes and the second washing cavity 031 is used to wash socks, etc.

[0072] 2 and 3, the arrows in Fig. 2 indicate the water flow paths within the small tub 03. A drainage channel 032 is provided in the side wall of the small tub 03 along its length, and the water inlet of the drainage channel 032 is located at the top of the wall of the small tub 03. A drainage hole 041 is provided in 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, and is then discharged to the bottom of the first pulsator 04 through the drainage hole 041, and then discharged from the drainage pipe below the machine body 01. During drainage, water does not flow into the large tub 02, so it is ensured that the water discharged from the small tub 03 does not splash onto the clothes in the large tub 02, the clothes in the large tub 02 do not get wet, and the large tub 02 and the clothes in the large tub 02 do not get contaminated.

[0073] The small tub 03 is a conical tube, and the inner diameter of the top end of the small tub 03 is larger than the inner diameter of the bottom end of the small tub 03. By designing the tub in a conical shape, the small tub 03 can eject water from the top of the small tub 03 at a relatively low rotation speed, and the water will flow into the drainage channel 032, thereby ensuring that the clothes in the small tub 03 are not easily thrown out.

[0074] Specifically, in this embodiment, the drainage channel 032 protrudes both inward and outward from the side wall of the small tank 03. Because the drainage channel 032 is arranged vertically and is a pipe of equal diameter, the portion that protrudes outward becomes larger as it goes downward, with the top hardly protruding outward at all, and the portion that protrudes inward becomes larger as it goes upward, with the top protruding inward almost completely and the bottom hardly protruding inward at all. The drainage channel 032 and the small tub 03 are integrally molded, thereby ensuring the structural strength of the drainage channel 032 and the small tub 03. In other embodiments, the drainage channel 032 may be provided only on the inner wall of the small tub 03 so as to protrude inward, or may be provided only on the outer wall of the small tub 03 so as to protrude outward.

[0075] The drain hole 041 is located below the drain channel 032, specifically directly below the drain channel 032, but may of course be located below the side. A drain hole 041 with a larger opening is provided directly below the drain channel 032, so that the water in the drain channel 032 can be quickly drained below the first pulsator 04 and then discharged through a drain pipe below the body 01. In another embodiment, multiple drain holes 041 with smaller openings may be provided below the drain channel 032, which may result in a slightly slower drainage speed but may effectively ensure the structural strength of the first pulsator 04.

[0076] The first pulsator 04 has an insertion opening, and the drainage channel 032 is inserted into the insertion opening. 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 in the bottom of the drain channel 032 located inside the small tank, and after the small tank 03 is attached, the part of the convex rib 042 located outside the small tank 03 is exposed, and the part located inside the small tank 03 is embedded in the groove.

[0077] Regarding the arrangement of the drain hole 041, providing the drain hole 041 below the drain channel 032 does not limit the present invention. As long as the drainage channel 032 is connected to the drainage channel 032 and the water in the drainage channel 032 can be drained to the bottom of the first pulsator 04, a person skilled in the art may adopt other arrangements in other embodiments without departing from the principles of the present invention. For example, the first pulsator 04 is provided with a water-repellent rib, and a drainage cavity is provided horizontally inside the water-repellent rib. The drain hole 041 is provided in the bottom wall of the drain cavity, and a communication hole is provided in the outer wall of the small tank 03, which allows the drain path 032 to communicate with the drain cavity, allowing water in the drain path 032 to flow into the drain cavity, and then flow through the drain cavity to the drain hole 041, and is discharged below the first pulsator 04 through the drain hole 041. The water is then discharged from a drain pipe below the body 01. All of these do not deviate from the basic principle of the present invention, and therefore fall within the protection scope of the present invention.

[0078] Two drainage channels 032 are symmetrically arranged along the circumferential direction on the side wall of the small tank 03, ensuring that the water in the small tank 03 can be quickly discharged without the need to install more drainage channels 032, simplifying the overall structure while reducing manufacturing difficulties and costs.

[0079] The number of drainage channels 032 is not limited to two, and more may be provided without departing from the principles of the present invention. Specifically, a plurality of drainage channels 032 may be provided at intervals along the circumferential direction of the side wall of the small tank 03. Specifically, the number may be three, four, or five. Since these do not deviate from the basic principles of the present invention, they are included in the scope of protection of the present invention.

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

[0081] SUMMARY OF THE INVENTION The present invention aims to solve the problem of the inconvenience of attaching and detaching the small tub in a conventional double-tub washing machine.

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

[0083] The washing machine includes a 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, a second pulsator 05, an engagement block 033, a drive block 034, an elastic member 037, and a fixed block 041.

[0084] As shown in Figure 5, the large tub 02 is rotatably mounted within the body 01, the first pulsator 04 is mounted within the large tub 02 and is located at the bottom of the large tub 02, and the first pulsator 04 and the large tub 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 ensuring that the clothes in the large tub 02 are washed effectively.

[0085] The small tank 03 is provided in the large tank 02 and is arranged coaxially with the first pulsator and the large tank 02, and by attaching the small tank 03 to the first pulsator 04, the first pulsator 04 can rotate and drive the small tank 03 in synchronization. A drain channel 032 is provided in the side wall of the small tub 03 along its length, and a drain hole corresponding to the drain channel 032 is provided in the first pulsator 04, and the drain hole is located directly below the drain channel 032. There are two drain channels 032, and they are arranged symmetrically in the small tub 03. The small tub 03 is a conical tube, and the inner diameter of the top end is larger than the inner diameter of the bottom end. As the small tub 03 rotates, the water in the small tub 03 moves to the top, then flows downward along the drainage channel 032, and finally flows downward through the drainage holes into the first pulsator 04, so that the water in the small tub 03 does not come into contact with the inner wall of the large tub 02 or the clothes in the large tub 02.

[0086] As shown in FIGS. 6 to 10, the small tank 03 and the first pulsator 04 are specifically detachably engaged with each other. In this embodiment, the small tub 03 and the first pulsator 04 are quickly and detachably connected, so that when clothes are washed using only the large tub 02 and the small tub 03 is not needed, the small tub 03 can be quickly removed, and when clothes need to be washed using 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 provided on the bottom of the small tank 03, and a position limiting groove 0411 is provided in the first pulsator 04. The engaging block 033 extends at least partially within the position limiting groove 0411, thereby limiting and fixing the position of the small tank 03, and when the engaging block 033 is removed from the position limiting groove 0411, the position limiting and fixing of the small tank 03 can be released, thereby making it easier to remove the small tank 03 from the first pulsator 04. Specifically, the engaging block 033 is moved and partially extended into the position limiting groove 0411 to limit and fix the position of the small tank 03, thereby completing the installation of the small tank 03. The installation method is simple and quick. The engaging block 033 is moved so as to disengage from the position limiting groove 0411, thereby releasing the position limit and fixation on 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.

[0088] Specifically, the end of the engagement block 033 can extend into the position limiting groove 0411 to limit and fix the position of the small tank 03. A mounting groove is provided at the bottom of the small tank 03, and the engaging block 033 is provided slidably within the mounting groove. The mounting groove is provided toward the outside of the small tank 03, and the extension line of the mounting groove in the length direction can extend to the central axis of the small tank 03. The elastic member 037 is disposed in the mounting groove, and both ends of the elastic member 037 act on the bottom of the mounting groove and the engaging block 033 respectively, and the elastic member 037 can drive the engaging block 033 to partially extend into the position limiting groove 0411. The elastic member 037 is specifically a compression spring, and a connecting post 0332 is provided at the end of the engagement block 033, and the spring is fitted into the connecting post. The connecting post 0332 limits the position of the spring, thereby ensuring the stability of the spring, so that the spring can effectively slide 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 engaging block 033 that is remote from the elastic member 037 can be kept in a state of always extending 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 allow the end of the engaging block 033 to extend into the position limiting groove 0411 .

[0089] The engaging block 033 is provided with a receiving groove 0331 in the middle portion of the engaging block 033 , and the driving block 034 is provided in the receiving groove 0331 . The drive block 034 has a first inclined surface 0341 facing upward, and the engagement block 033 has a second inclined surface 0333 facing downward. The second inclined surface 0333 is located at the end closer to the elastic member 037, i.e., the end farther 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 to move away from the position limiting groove 0411, thereby causing the engagement block 033 to disengage from the position limiting groove 0411.

[0090] A receiving 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 receiving hole 038 and extends upward from the small tank 03. When the connecting rod 035 is pulled upward, the driving block 034 can be moved upward, thereby driving the engaging block 033 to disengage from the position limiting groove 0411, and after the connecting rod 035 is pushed downward, it no longer limits the position of the engaging block 033, and under the action of the elastic member 037, the engaging block 033 can be driven toward one end of the position limiting groove 0411, so that the engaging block 033 partially extends into the position limiting groove 0411.

[0091] Preferably, in this embodiment, there are two connection positions where the small trough 03 and the first pulsator 04 are engaged, and they are arranged symmetrically. That is, the number of engaging blocks 033, the number of elastic members 037, and the number of fixing blocks 041 are all two. In other embodiments, a person skilled in the art may select multiple connection positions according to connection requirements, and 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 pivotally connected to the top of the small tub 03, the handle 036 being connected to the top of the connecting rod 035, such that pulling the handle 036 upward can move the connecting rod 035 upward. Specifically, the handle 036 is provided with a connecting pin 0361, which is located above the pivotal connection between the small tank 03 and the handle 036, so that when the handle 036 is pulled upward, the connecting pin 0361 can move in an arc. A long and narrow hole 0351 is horizontally formed at the top of the connecting rod 035, and a connecting pin 0361 is drilled in the long and narrow hole 0351. When the handle 036 is pulled upward, the connecting pin 0361 moves in an arc and also moves horizontally relative to the long and narrow hole 0351, thereby moving the connecting rod 035 vertically upward, thereby moving the driving block 034 upward and driving the engaging 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 driving block 034 and preventing damage to the connection between the connecting rod 035 and the driving block 034.

[0093] As shown in FIGS. 6 to 10, the fixed block 041 is fixed to the first pulsator 04, and the two are fixed together with screws. A position limiting groove 0411 is provided in the fixed block 041. To facilitate installation, the bottom of the engaging block 033, which is closest to the fixed block 041, is beveled, and the upper edge of the fixed block 041 is also chamfered, allowing the engaging block 033 to be better compressed and installed.

[0094] The fixed block 041 is provided with an observation window through which the inside of the position limiting groove 0411 can be observed, and through the observation window 0412, it can be observed whether the engaging block 033 is extending into the position limiting groove 0411, thereby making it possible to determine whether the small tank 03 is attached in the specified position. Specifically, when the engagement block 033 can be seen from the observation window 0412, it means that the engagement block 033 extends into the position limiting groove 0411, and at this time, the engagement block 033 can limit and fix the position of the small tank 03, indicating that the small tank 03 is installed in the specified position. When the engagement block 033 cannot be seen from the observation window 0412, it means that the engagement block 033 does not extend into the position limiting groove 0411, and it cannot limit and fix the position of the small tank 03, indicating that the small tank 03 is not installed in the specified position. Whether the small tub 03 is installed in the specified position can be determined through the observation window 0412. The observation method is simple, and the structure of the observation window 0412 is also simple, so the structure of the washing assembly is also simple and the cost is low.

[0095] For ease of observation and judgment, the engaging block 033 and the fixed block 041 are different in color. The first pulsator 04 and the fixed block 041 are usually light-colored, such as white or gray, and at least the end of the engaging block 033 that can extend into the position limiting groove 0411 is red, blue, or green. Preferably, the engaging block 033 is entirely red and has a bright color, so that it is easy to observe whether the end of the engaging block 033 extends into the position limiting groove 0411 or not.

[0096] 5, the second pulsator 05 is provided in 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 on the same axis. 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] Specifically, the large tank 02, the first pulsator 04, and the second pulsator 05 are rotationally driven by a drive mechanism 06. The drive mechanism 06 is provided in the machine body 01 and is located at the bottom of the first pulsator 04, and the large tub 02, the first pulsator 04, and the second pulsator 05 are all power-transmitted and connected 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 tub 02, the first pulsator 04, and the second pulsator 05 are each connected to different output ends of the clutch, so that the drive motor can drive the large tub 02, the first pulsator 04, and the second pulsator 05 to rotate simultaneously or separately, and can also control the rotation of the large tub 02, the first pulsator 04, and the second pulsator 05, and can also control the operation of one, two, or three of these 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 to the first output shaft and is rotatable relative to the first output shaft, and the third output shaft is fitted to the second output shaft and is rotatable relative to the second output shaft. The second pulsator 05 is fitted to 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 drive the second pulsator 05 to rotate via the first output shaft. The second output shaft is fixedly connected to the first pulsator 04, so that the drive mechanism 06 can drive the first pulsator 04 to rotate via the second output shaft. The third output shaft is fixedly connected to the large tank 02, so that the drive mechanism 06 can drive the large tank 02 to rotate 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 a bearing. 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 a first washing cavity 021, and the space within the small tub 03 is a second washing cavity 031.

[0100] The large tub 02, the first pulsator 04, and the second pulsator 05 can rotate in different directions, and whether they rotate or not can be controlled individually, so the first washing cavity 021 and the second washing cavity 031 can be used simultaneously, or either one can be used individually. If the number of clothes is relatively small, the clothes can be washed in only the second washing cavity 031; if the number of clothes is slightly large, the clothes can be washed in only the first washing cavity 021; if the number of clothes is relatively large, the clothes can be washed in both the first washing cavity 021 and the second washing cavity 031 at the same time. Of course, the first washing cavity 021 and the second washing cavity 031 may also be used to wash different types of clothes, for example, the first washing cavity 021 may be used to wash regular outerwear 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] To solve the problem that in a conventional double-tub washing machine, it is not possible to determine whether a small tub is attached at a predetermined position.

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

[0104] The washing machine includes a 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, a second pulsator 05, an engagement block 033, a drive block 034, an elastic member 037, and a fixed block 041.

[0105] As shown in Figure 5, the large tub 02 is rotatably mounted within the machine body 01, the first pulsator 04 is mounted within the large tub 02 and at the bottom of the large tub 02, and the first pulsator 04 and the large tub 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 ensuring that the clothes in the large tub 02 are effectively washed.

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

[0107] 6 to 10, the small tub 03 and the first pulsator 04 are removably engaged. In this embodiment, the small tub 03 and the first pulsator 04 are quickly and detachably connected, so that when clothes are washed using only the large tub 02 and the small tub 03 is not needed, the small tub 03 can be quickly removed, and when clothes need to be washed using the small tub 03, the small tub 03 can be quickly attached to the first pulsator 04.

[0108] Specifically, a position limiting groove 0411 is provided on one of the first pulsator 04 and the bottom of the small tub 03, and a movable engagement block 033 is provided on the other. The second pulsator 0 is provided with an observation window 0412 through which the position of the engagement block 033 can be observed. The engagement block 033 can extend at least partially into the position limiting groove 0411 to limit and fix the position of the small tank 03, and when the engagement block 033 is released from the position limiting groove 0411, the position limit and fixation of the small tank 03 can be released. Through the observation window 0412, it is possible to observe whether the engaging block 033 is extended into the position limiting groove 0411, and to determine whether the small tank 03 is attached at the predetermined position.

[0109] Preferably, the engaging 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 within the position limiting groove 0411, thereby limiting and fixing the position of the small tank 03, and when the engaging block 033 is removed from the position limiting groove 0411, the position limiting and fixing of the small tank 03 can be released, thereby making it easier to remove the small tank 03 from the first pulsator 04. Specifically, the installation of the small tank 03 is completed by moving the engaging block 033 and extending it partially into the position limiting groove 0411, thereby limiting the position of the small tank 03 and fixing it, and the installation method is simple and quick. The position limit and fixing of the small tank 03 are released by moving the engaging block 033 so that it is removed from the position limiting groove 0411, and the small tank 03 can be removed, and 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 can extend into the position limiting groove 0411 to limit and fix the position of the small tank 03. An attachment groove is provided at the bottom of the small tank 03, and the engagement block 033 is slidably provided within the attachment groove. The attachment groove is provided toward the outside of the small tank 03, and the extension line of the attachment groove in the longitudinal direction can extend to the central axis of the small tank 03. An 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 engaging block 033, respectively, so that the elastic member 037 can drive the engaging block 033 to partially extend into the position limiting groove 0411. The elastic member 037 is specifically a compression spring, and a connecting post 0332 is provided at the end of the engaging block 033, which limits the position of the spring to ensure its stability, so that the spring can effectively slide the engaging block 033 to partially extend into the position limiting groove 0411. Due to the action of the elastic member 037, the end of the engagement block 033 away from the elastic member 037 can always be kept 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 it can cause the end of the engagement block 033 to extend within the position limiting groove 0411.

[0111] The engaging block 033 is provided with a receiving groove 0331 in the middle portion of the engaging block 033 , and the driving block 034 is provided in the receiving groove 0331 . The drive block 034 is provided with a first inclined surface 0341 facing upward, and the engagement block 033 is provided with a second inclined surface 0333 facing downward. The second inclined surface 0333 is located at the end closer to the elastic member 037, i.e., the end farther 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 toward the elastic member 037 and slides against the second inclined surface 0333, driving the engagement block 033 to move away from the position limiting groove 0411, whereby the engagement block 033 disengages 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 driving 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 driving block 034 moves upward, thereby driving the engaging block 033 to disengage from the position limiting groove 0411. After the connecting rod 035 is pushed downward, the position of the engaging block 033 is no longer limited, and the elastic member 037 drives the engaging block 033 toward one end of the position limiting groove 0411, so that the engaging block 033 partially extends into the position limiting groove 0411.

[0113] Preferably, in this embodiment, there are two connection positions where the small trough 03 and the first pulsator 04 are engaged, and they are arranged symmetrically. That is, the number of the engaging blocks 033, the number of the elastic members 037, and the number of the fixing blocks 041 are all two. In other embodiments, a person skilled in the art may select multiple connection locations according to the connection requirements, and multiple connection locations 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 pivotally connected to the top of the small tub 03, the handle 036 being connected to the top of the connecting rod 035, such that pulling the handle 036 upward can move the connecting rod 035 upward. Specifically, the handle 036 is provided with a connecting pin 0361, which is located above the pivotal connection between the small tank 03 and the handle 036, so that 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 in the elongated hole 0351. When the handle 036 is pulled upward, the connecting pin 0361 moves in an arc and also moves horizontally relative to the elongated hole 0351, thereby moving the connecting rod 035 vertically upward, thereby moving the driving block 034 upward and driving the engaging 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 driving block 034 and preventing damage to the connection between the connecting rod 035 and the driving block 034.

[0115] As shown in Figures 6 to 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 more effectively compressed when installed.

[0116] The observation window 0412 is provided on the fixed block 041, and specifically, it is used to observe the condition inside the position limiting groove 0411, that is, to observe whether the engaging block 033 is extending into the position limiting groove 0411. Through the observation window 0412, it is possible to observe whether the engaging block 033 is extending into the position limiting groove 0411 and determine whether the small tank 03 is attached in the specified position. Specifically, when the engagement block 033 can be seen from the observation window 0412, it means that the engagement block 033 extends into the position limiting groove 0411, and at this time, the engagement block 033 can limit and fix the position of the small tank 03, indicating that the small tank 03 is installed in the specified position. When the engagement block 033 cannot be seen from the observation window 0412, it means that the engagement block 033 does not extend into the position limiting groove 0411, and it cannot limit and fix the position of the small tank 03, indicating that the small tank 03 is not installed in the specified position. Whether the small tub 03 is installed in the specified position can be determined through the observation window 0412. The observation method is simple, and the structure of the observation window 0412 is also simple, so the structure of the washing assembly is also simple and the cost is low.

[0117] For ease of observation and determination, the engaging block 033 and the fixed block 041 are different in color. The first pulsator 04 and the fixed block 041 are usually light-colored, such as white or gray, and at least the end of the engaging block 033 that can extend into the position limiting groove 0411 is red, blue, or green. Preferably, the engaging block 033 is entirely red and light-colored, so that it is easy to observe whether the end of the engaging block 033 extends into the position limiting groove 0411.
