[0002] Washing equipment has become a common household appliance due to its convenience. The barrel assembly of the washing equipment is arranged in the body, and the clothes are washed by rotating the barrel assembly.

[0003] The tub assembly of a washing machine typically includes an inner tub and an outer tub. A pulsator is located at the bottom of the inner tub. The rotation of the pulsator agitates the clothes and water in the inner tub during washing, achieving the desired effect. Currently, when washing clothes in washing machines, the inner and outer tubs are not sealed and independent. Water in the tub assembly resides in the inner tub and flows through it to the outer tub. Over time, a large amount of dirt accumulates between the inner and outer tubs, easily breeding bacteria that attach to the outer tub, contaminating the clothes the next time they are washed. Therefore, using a separate inner tub, isolated from the outer tub, can avoid this problem.

[0004] In view of this, the present invention is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0041] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0042] like Figures 1 to 5As shown, the present invention provides a barrel assembly 2, comprising an inner barrel 21 and a middle barrel 22, wherein the inner barrel 21 has a first open end, and further comprising an inner barrel cover 3 installed at the first open end of the inner barrel 21, wherein a first connecting structure 212 is provided on the inner barrel cover 3;

[0043] The middle barrel 22 has a second open end, and the second open end has a second connecting structure 222 that cooperates with the first connecting structure 212;

[0044] The inner barrel 21 can be detachably installed in the middle barrel 22, and is connected to the first connecting structure 212 and the second connecting structure 222 so that the two can move as a whole in the rotation direction.

[0045] When the barrel assembly 2 of the present invention is working, the clothes and washing water are located in the inner barrel 21, and the middle barrel 22 drives the inner barrel 21 to rotate. The middle barrel 22 provides support and power for the inner barrel 21, driving the inner barrel 21 to rotate to clean the clothes. The inner barrel 21 drives the washing water and clothes inside it to rotate. As the washing water rotates, collision and friction occur between the clothes and the inner barrel 21, thereby achieving the purpose of cleaning the clothes.

[0046] Since the inner tub cover 3 is assembled at the first open end of the inner tub 21, a closed and independent space is formed inside the inner tub 21. The washing water will not flow out of the inner tub 21, and the washing water outside the inner tub 21 will not enter the inner tub 21. The clothes are located in the inner tub 21 and will not be contaminated by the dirty washing water outside the inner tub 21. This can ensure that the clothes are clean and tidy, and improve the hygiene and safety of the washing process.

[0047] A water level is set on the wall of the inner tub 21. During each wash cycle, the water level can be below or close to the water level. A first drain hole is provided above the water level. During the wash cycle, any water above the water level is ejected through the first drain hole due to centrifugal force. After the wash cycle is complete, the tub assembly 2 spins at high speed, generating centrifugal force to move the wash water within the inner tub 21 upward along the tub wall. Once the water level exceeds the water level, the water is ejected through the first drain hole. Once the water level reaches a certain level, the clothes are effectively dried.

[0048] The barrel wall of the inner barrel 21 has a water guide groove 214, which is not parallel to the axis of the barrel body of the inner barrel 21. That is to say, the water guide groove 214 extends upward from the bottom of the barrel wall of the inner barrel 21, and the distance from the central axis of the barrel body of the inner barrel 21 gradually increases, ensuring that during the drainage process of the inner barrel 21, the water flow can be discharged from the first drainage hole along the water guide groove 214, thereby improving the drainage efficiency.

[0049] A plurality of water guide grooves 214 are provided, and the plurality of water guide grooves 214 extend upward from the bottom of the barrel wall of the inner barrel 21 and are evenly distributed along the circumference of the barrel wall of the inner barrel 21 .

[0050] At least one side wall of the water guide groove 214 extends obliquely upward away from the other side wall, and the side walls of each water guide groove 214 on the same side have the same inclination angle. That is, if the barrel body where the water guide groove 214 is located is unfolded to form a plane (the plane is generally rectangular), one of the shorter sides of the plane is defined as the width of the plane, the side wall of the water guide groove 214 closer to the wide side of the plane is defined as the first side wall, and the other side wall of the water guide groove 214 is defined as the second side wall, the first side walls of the multiple water guide grooves 214 all have the same inclination angle from bottom to top. This allows water to flow upward from the bottom of the inner tub 21 along the water guide groove 214 and be discharged from the first drain hole of the inner tub 21.

[0051] The bottom of the inner barrel 21 is provided with a plurality of third protrusions, and the bottom of the middle barrel 22 is correspondingly provided with a fourth protrusion that cooperates with the third protrusions on the bottom of the inner barrel 21. The two cooperate with each other. On the one hand, the inner barrel 21 and the middle barrel 22 are quickly fixed. On the other hand, the protrusions on the bottom of the inner barrel 21 are in the shape of a pulsator, which can improve the washing effect.

[0052] The inner tub 21 mainly serves as a replacement and isolation device. During the washing process, the force applied to the inner tub 21 can be transferred to the middle tub 22, which provides support for the inner tub 21 and is the main load-bearing component. The inner tub 21 is relatively light and easy to carry. Each user can have their own inner tub 21 and carry their own inner tub 21 to wash clothes. When washing clothes, place your inner tub 21 into the middle tub 22, cover the inner tub lid 3, and the middle tub 22 drives the inner tub 21 to rotate and wash clothes. During the washing process, the barrel body of the inner tub 21 forms an independent space, and the clothes are isolated during the washing process, which can ensure the cleanliness of the clothes and also ensure the hygiene and safety of the washing process.

[0053] Preferably, the inner barrel cover 3 is arranged axially higher than the second open end of the middle barrel 22;

[0054] The first connecting structure 212 is arranged around the inner tub cover 3 and is located outside the first open end of the inner tub 21 .

[0055] As an embodiment, the first connecting structure 212 is arranged along the radial direction of the inner barrel cover 3, that is, the first connecting structure 212 is installed around the inner barrel cover 3, and the second connecting structure 222 is installed at the second open end of the middle barrel 22. The first connecting structure 212 and the second connecting structure 222 are in the same plane in the radial direction. Through the matching connection of the first connecting structure 212 and the second connecting structure 222, the inner barrel 21 is installed on the middle barrel 22. However, since the first connecting structure 212 and the second connecting structure 222 are in the same plane, the gap between the inner barrel 21 and the middle barrel 22 becomes larger, thereby reducing the volume of the inner barrel 21.

[0056] As another embodiment, the first connecting structure 212 is provided on the lower surface of the inner tub cover 3 and extends toward the bottom of the inner tub 21, forming a first concave-convex structure. The second connecting structure 222 is provided on the middle tub 22 below the first connecting structure 212 and extends upward to form a second concave-convex structure, which is connected to the first connecting structure 212 in a concave-convex manner. In other words, the first concave-convex structure and the second concave-convex structure are assembled up and down, so that the first concave-convex structure and the second concave-convex structure are located in two different planes in the radial direction, which can reduce the gap between the inner tub 21 and the middle tub 22 and increase the volume of the inner tub 21.

[0057] Preferably, the inner tub cover 3 includes a cover body and an outer edge 31, the cover body is assembled on the first open end of the inner tub 21, and the outer edge 31 is arranged around the cover body and extends outward to the outside of the first open end;

[0058] The first concave-convex structure is provided on the lower surface of the outer edge 31 .

[0059] Preferably, the second open end of the middle barrel 22 has an outer flange 221, which extends radially outward from the second open end, and is arranged opposite to the outer edge 31 of the inner barrel cover 3; the second concave-convex structure is arranged on the surface of the outer flange 221 facing the outer edge 31, and the assembly of the inner barrel 21 and the middle barrel 22 is achieved through the concave-convex cooperation of the first concave-convex structure and the second concave-convex structure.

[0060] Preferably, the barrel assembly 2 further includes a balancing ring 4 mounted on the outer wall of the middle barrel 22, close to the second open end of the middle barrel 22;

[0061] As an alternative to providing the second concave-convex structure on the surface of the outer flange 221 facing the outer edge 31 , the balancing ring 4 has a mounting surface opposite to the outer edge 31 , and the second concave-convex structure is provided on the mounting surface.

[0062] In addition, in order to improve the aesthetics of the barrel assembly 2 , the barrel assembly 2 further includes an edge connected to the extended end of the outer flange 221 , and the edge extends from the extended end of the outer flange 221 toward the bottom of the middle barrel 22 .

[0063] Preferably, the first concave-convex structure includes a plurality of first protrusions, which are evenly distributed along the circumferential direction, and a plurality of first grooves 213 are formed between adjacent first protrusions and the outer edge 31 .

[0064] The second concave-convex structure includes a plurality of second protrusions. Adjacent second protrusions and first protrusions are evenly and alternately arranged, and a plurality of second grooves 223 are formed between adjacent second protrusions.

[0065] Multiple first protrusions are correspondingly arranged in the second groove 223, and multiple second protrusions are correspondingly arranged in the first groove 213. The adjacent first protrusions and second protrusions fit tightly with each other, which can generate friction, thereby improving the tightness of the installation of the inner barrel 21 and the middle barrel 22, and preventing the centrifugal force generated by the rotation of the inner barrel 21 and the middle barrel 22 from throwing the inner barrel 21 out of the middle barrel 22.

[0066] Preferably, the inner barrel cover 3 also includes an annular body 39, which is installed at the first open end of the inner barrel 21, and the outer edge 31 is arranged on the outer periphery of the body 39. The middle opening of the body 39 constitutes a clothing access opening, and the cover body can be installed on the body 39 in an openable and closable manner for opening and closing the clothing access opening.

[0067] An annular flange 30 is provided on the upper surface of the main body 39, and the inner side of the main body 39 extends downwardly to form a plug-in portion 32 installed at the first opening end of the inner barrel 21. The inner wall of the plug-in portion 32 extends inwardly to form a support platform 33 for supporting the cover body, and the two opposite sides of the support platform 33 respectively form a cover hinge portion 34 and a cover locking portion 35, and the other two opposite sides of the support platform 33 respectively form a handle hinge portion 36. The annular flange 30 extends outward to be connected to the plug-in portion 32.

[0068] Preferably, one side of the cover is pivotally mounted on the body 39 , and the opposite side is locked to the body 39 .

[0069] The cover hinge portion 34 can be a hinge, and the user manually opens the cover; the cover hinge portion 34 can also be a torsion spring, and a button is set on the cover. The user presses the button to automatically open the cover and put clothes into the clothing access port.

[0070] The cover locking portion 35 includes a first through hole 351 , and the cover has a second through hole corresponding to the first through hole 351 . The cover is fixed to the support platform 33 via a connecting member.

[0071] Preferably, a handle 38 is further provided on the main body 39, the shape of the handle 38 is adapted to the main body 39, and the handle 38 is rotatably mounted on the main body 39. A receiving groove 37 is provided on the main body 39 for accommodating the handle 38 flipped on the main body 39, so that the handle 38 and the main body 39 can remain relatively stationary.

[0072] Preferably, a snap-fitting portion 381 is further provided on the handle 38. When the inner barrel 21 needs to be replaced, the handle 38 is rotated to take the handle 38 out of the accommodating groove 37, and the snap-fitting portions 381 on the two handles 38 are snapped together. The user provides a force to pull the handle 38 to remove the inner barrel cover 3 and replace it. After the inner barrel 21 is assembled, the snap-fitting portions 381 on the two handles 38 are manually opened, and the handle 38 is rotated again to place the handle 38 in the accommodating groove 37.

[0073] The present invention also provides a washing device, including a barrel assembly 2, an outer barrel 1 and a driving mechanism 5. The barrel assembly 2 is arranged in the outer barrel 1. The driving mechanism 5 provides a force for the barrel assembly 2 to rotate. The peripheral wall and / or bottom wall of the middle barrel 22 of the barrel assembly 2 has a water outlet. Under the action of the driving mechanism 5, the washing water discharged through the first drainage hole of the inner barrel 21 enters the middle barrel 22, is discharged from the water outlet of the middle barrel 22 to the outer barrel 1, and is discharged to the outside of the washing device through the drainage port of the outer barrel 1.
