Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] like Figures 1 to 4 As shown in the embodiment of the present invention, a pulsator 1 of a garment processing device is introduced. The center of the pulsator 1 is provided with an upward-opening assembly groove 2. The bottom 201 and / or the wall 202 of the assembly groove 2 are provided with protruding and / or recessed reinforcing structures 3.

[0043] By setting up the above-mentioned reinforcement structure 3 in the assembly groove 2, the overall structural strength and load-bearing capacity of the assembly groove 2 are enhanced, and the deformation or even cracking of the bottom 201 and / or wall 202 of the assembly groove 2 due to excessive stress is avoided.

[0044] In one embodiment of the present invention, an annular protrusion 210 is provided at the center of the assembly groove 2, and the inner circumferential side of the reinforcing structure 3 is connected to the outer circumferential wall of the annular protrusion 210. Preferably, a fixing hole 230 is provided on the inner circumferential side of the annular protrusion 210 for screws to pass through. The screw moves downward from above the impeller 1 into the assembly groove 2 and passes through the fixing hole 230 to connect with the drive shaft of the garment processing device.

[0045] In another preferred embodiment of the present invention, the inner circumferential side of the reinforcing structure 3 is spaced apart from the center of the assembly groove 2 by a certain distance; this is to prevent the reinforcing structure 3 from forming a relatively independent chamber in the assembly groove 2. While improving the structural strength of the assembly groove 2, a flow channel is formed in the center of the assembly groove 2 that communicates with the space between the reinforcing structures 3, so as to prevent the accumulation of dirt and mold in the space between the reinforcing structures 3.

[0046] In an embodiment of the present invention, the reinforcing structure 3 is positioned near the outer periphery of the assembly groove 2.

[0047] In an embodiment of the present invention, an annular protrusion 210 is provided at the center of the assembly groove 2, and the inner peripheral sidewall of the reinforcing structure 3 is provided at a certain distance from the outer peripheral wall of the annular protrusion 210.

[0048] In embodiments of the present invention, the reinforcing structure 3 extends radially along the assembly groove 2 or spirally extends from the outer periphery to the center along the circumference of the assembly groove 2.

[0049] In an embodiment of the present invention, the reinforcing structure 3 extends continuously along the circumferential direction of the assembly groove 2 to form an arc-shaped strip reinforcing structure 3, thereby improving the circumferential structural strength of the assembly groove 2.

[0050] In one embodiment of the present invention, the reinforcing structure 3 is connected end to end along the assembly groove 2 to form a ring-shaped reinforcing structure 3.

[0051] In another preferred embodiment of the present invention, multiple reinforcing structures 3 are arranged at intervals along the circumferential direction of the assembly groove 2 to form an uneven surface in the circumferential direction of the assembly groove 2, thereby further improving the overall structural strength of the assembly groove 2.

[0052] In an embodiment of the present invention, the bottom 201 of the assembly tank 2 is provided with a plurality of drainage holes 220, each drainage hole 220 being located in the interval area between two adjacent reinforcing structures 3; so that water flowing to the bottom 201 can be discharged from the assembly tank 2 through the drainage holes 220, preventing the assembly tank 2 from becoming moldy due to dampness. At the same time, the reinforcing structure 3 can improve the structural strength of the bottom 201 around the drainage holes 220, preventing the bottom 201 around the drainage holes 220 from deforming.

[0053] In an embodiment of the present invention, the reinforcing structure 3 is arranged in a ring at intervals within the assembly groove 2.

[0054] In embodiments of the present invention, the reinforcing structure 3 is arranged in multiple rings within the assembly groove 2.

[0055] In embodiments of the present invention, the reinforcing structure 3 and the assembly groove 2 are separately arranged, or the reinforcing structure 3 and the assembly groove 2 are integrally connected.

[0056] In one embodiment of the present invention, the reinforcing structure 3 is a plate-shaped structure or a block-shaped structure; preferably, the reinforcing structure 3 is a plate-shaped structure with the plate surface vertically arranged; more preferably, the plate surface of the plate-shaped reinforcing structure 3 is an arc surface, and the axis of the arc surface is coaxial with the central axis of the assembly groove 2.

[0057] In an embodiment of the present invention, the reinforcing structure 3 is a reinforcing press 301 protruding into the assembly groove 2; while improving the structural strength of the assembly groove 2, it avoids increasing the overall weight of the impeller 1.

[0058] In one embodiment of the present invention, one end of the reinforcing mold 301 faces the center of the assembly groove 2, and the other end faces the outer peripheral groove wall 202 of the assembly groove 2; preferably, the reinforcing mold 301 is a strip extending in the radial direction corresponding to the assembly groove 2.

[0059] In another preferred embodiment of the present invention, the reinforced molding 301 extends in an arc shape along the outer peripheral groove wall 202 of the assembly groove 2.

[0060] In embodiments of the present invention, the reinforced pressure mold 301 smoothly transitions into contact with the bottom 201 and / or wall 202 of the assembly tank 2; this allows water on the reinforced pressure mold 301 to flow smoothly to the bottom 201 of the assembly tank 2 and be discharged through the drain hole 220 of the bottom 201, avoiding the formation of a sanitary dead corner between the reinforced pressure mold 301 and the assembly tank 2, which could lead to the accumulation of dirt; in addition, the chamfer of the smooth transition has higher structural strength than a right-angle corner, preventing breakage at the junction of the reinforced pressure mold 301 and the assembly tank 2, thereby further improving the structural strength of the assembly tank 2.

[0061] In embodiments of the present invention, the drain hole 220 is at least partially located on the curved surface where the reinforcing structure 3 and the bottom of the groove 201 smoothly transition; while ensuring the screw is stably installed in the drain hole 220, the structural strength of the drain hole 220 wall is enhanced.

[0062] In embodiments of the present invention, the reinforcing molding 301 includes a first reinforcing molding 310, which protrudes into the assembly groove 2 from the area where the groove bottom 201 and the groove wall 202 are close to each other; so that the first reinforcing molding 310 can not only improve the structural strength of the groove bottom 201 and the groove wall 202 of the assembly groove 2, but also strengthen the structural strength of the joint between the groove bottom 201 and the groove wall 202 of the assembly groove 2.

[0063] In one embodiment of the present invention, the projection of the first reinforced compression type 310 on the bottom of the groove 201 is a fan shape, with the apex of the fan shape facing the center of the bottom of the groove 201.

[0064] In another embodiment of the present invention, the projection of the first reinforcing pressure type 310 on the bottom of the tank 201 is an annular fan shape; preferably, the center of the annular fan shape is located at the center of the bottom of the tank 201; specifically, the inner peripheral edge of the fan shape is parallel to the outer peripheral sidewall of the annular protrusion 210; so that the cross-sectional area of ​​the first reinforcing pressure type 310 is larger, the overall structural strength of the bottom of the tank 201 is improved, and the inner peripheral wall of the first reinforcing pressure type 310 can guide water to flow to the drain hole 220 between the first reinforcing pressure types 310, thereby improving the drainage effect of the assembly tank 2.

[0065] In an embodiment of the present invention, the central angle of the first reinforced compression type 310 is greater than or equal to 60 degrees and less than 180 degrees.

[0066] In embodiments of the present invention, the central angle of the first reinforcing pressure type 310 is greater than or equal to 90 degrees and less than 120 degrees, so that one to three first reinforcing pressure types 310 can be provided in the assembly groove 2. Preferably, the three first reinforcing pressure types 310 are equally spaced in the assembly groove 2 along the circumference of the assembly groove 2.

[0067] In an embodiment of the present invention, the radius of the inner peripheral sidewall of the first reinforcing molding 310 is less than or equal to half the radius of the assembly groove 2, so that the length of the first reinforcing molding 310 extending inward from the outer peripheral groove wall 202 of the assembly groove 2 is greater than or equal to half the radius of the assembly groove 2, thereby increasing the radial length of the first reinforcing molding 310 and further improving the structural strength of the assembly groove 2.

[0068] In an embodiment of the present invention, the outer peripheral sidewall of the annular protrusion 210 of the assembly groove 2 and the inner peripheral sidewall of the first reinforcing pressure type 310 have a certain gap in the radial direction of the assembly groove 2, so that an annular flow channel is formed between them, and the water in the assembly groove 2 can flow along the annular flow channel to the drain hole 220 between the first reinforcing pressure type 310.

[0069] In an embodiment of the present invention, each sidewall of the first reinforced pressure type 310 is smoothly connected to its top wall through a convex first curved surface 311; the first curved surface 311 forms a smooth surface at the corner between each sidewall and the top wall of the first reinforced pressure type 310, thereby improving the structural strength at the corner. At the same time, it can reduce the proportion of the horizontal surface of the top wall and reduce the amount of water remaining on the top wall of the first reinforced pressure type 310.

[0070] In an embodiment of the present invention, the length of the first curved surface 311 connected to the inner peripheral sidewall of the first reinforcing mold 310 in the radial direction of the assembly groove 2 is greater than or equal to one-third of the length of the first reinforcing mold 310 in the same direction.

[0071] In an embodiment of the present invention, the height of the first curved surface 311 in the vertical direction is greater than or equal to half of the height of the first forming.

[0072] In an embodiment of the present invention, the sidewalls of the first reinforced pressure type 310 are smoothly connected by a convex second curved surface 312. The adjacent side edges of the two first curved surfaces 311 and the top edges of the corresponding second curved surfaces 312 are smoothly connected by a convex transition surface 313, the width of which gradually increases from top to bottom. By setting the second curved surface 312 at the corner between the inner peripheral sidewall and the two end sidewalls of the first reinforced pressure type 310, the structural strength is improved while allowing water located on the inner peripheral side of the first reinforced pressure type 310 to flow smoothly through the second curved surface 312. The water is discharged through the drain hole 220 between the first reinforced pressure type 310; in addition, by setting a teardrop-shaped transition surface 313 at the two apex corners of the first reinforced pressure type 310, and cooperating with the first curved surface 311 and the second curved surface 312, the first reinforced pressure type 310 is a smooth pressure type as a whole. This allows the first reinforced pressure type 310 to effectively improve the overall structural strength of the assembly tank 2, while also guiding the water to flow smoothly to the bottom of the tank 201 and being discharged through the drain hole 220 of the bottom of the tank 201; at the same time, the first reinforced pressure type 310 has a beautiful shape, enhancing the overall aesthetics of the impeller 1.

[0073] In embodiments of the present invention, each sidewall of the first reinforced compression type 310 and the second curved surface 312 are smoothly connected to the bottom 201 of the assembly groove 2 through the concave third curved surface 314.

[0074] In an embodiment of the present invention, the outer peripheral sidewall of the annular protrusion 210 is smoothly connected to the bottom 201 of the assembly groove 2 through the concave fourth curved surface 211. The bottom edge of the fourth curved surface 211 is close to or smoothly connected to the bottom edge of the third curved surface 314. This allows the fourth curved surface 211 and each of the third curved surfaces 314 to cooperate in the assembly groove 2 to form an arc-shaped concave flow channel, which smoothly guides water to the drain outlet at the bottom 201 of the assembly groove 2, thereby improving the drainage effect.

[0075] In embodiments of the present invention, each drain outlet is located between the opposite ends of the two first reinforced pressure type 310, and the drain outlet is at least partially located within the corresponding third curved surface 314.

[0076] In an embodiment of the present invention, the two end sidewalls and the top wall of the first reinforced compression type 310 are smoothly connected to the groove wall 202 of the assembly groove 2 through the concave fifth curved surface 315; preferably, the radii of curvature of the fifth curved surface 315 and the third curved surface 314 are equal.

[0079] In an embodiment of the present invention, the impeller 1 includes an impeller box located inside the assembly groove 2, and the impeller box is connected to the bottom wall of the impeller cover 4; preferably, the impeller box abuts against the top of the first reinforcing pressure type 310; another preferred embodiment is that the top wall of the first reinforcing structure 3 is arranged at a distance from the bottom wall of the impeller box in the vertical direction.
