Description

Technical Field

[0001] The utility model relates to the technical field of impeller components, in particular to a detachable impeller component. Background Art

[0002] The bottom of the drum of the pulsator washing machine is equipped with a disc impeller with protruding ribs. Driven by the impeller, the water flow in the drum forms a vortex that sometimes rotates right and sometimes rotates left, driving the fabric to rotate and tumble, so that the dirt on the clothes can be removed. The pulsator washing machine is a type of washing machine. The motor drives the impeller to rotate, and the clothes are constantly tumbling up and down with the water. There are several types of washing clothes, such as single barrel, nested barrel, and double barrel. Its structure is relatively simple, easy to maintain, and has a high cleaning rate, but it has a high wear rate on clothes and uses a lot of water. The impeller assembly is its important component structure.

[0003] The existing patent technology CN202220903467.7 proposes that in the prior art, in order to facilitate the disassembly of the impeller, bolts are usually used to fix the impeller. However, if only one bolt is subjected to force, the bolt is easy to loosen when the impeller rotates for a long time. If multiple bolts are used for multi-point fixing, the impeller can only be disassembled one by one within the limited space inside the washing machine during disassembly, which makes the disassembly of the impeller very troublesome. Based on this, a impeller assembly that is easy to disassemble is proposed.

[0004] The impeller assembly can be fixed to the fixing hole by turning the adjusting screw in different directions with a screwdriver, or the fixing block can be detached from the fixing hole, and the impeller body can be removed by pulling the impeller body upwards. The operation is simple, not only convenient for quick disassembly of the impeller body, but also the fixing block is inserted into the fixing hole to bear force, while the adjusting screw itself is not subjected to force and is not easy to loosen. However, after the connection and assembly are completed, the impeller assembly and the mounting structure are simply fixed by the docking between the fixing block and the fixing hole, which is difficult to meet the strength requirements of the impeller assembly during high-speed rotation during operation, and the screw structure is prone to loosening due to friction with clothes during long-term operation. For this reason, we have designed a detachable impeller assembly to solve the above problems. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a detachable impeller assembly, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the utility model is implemented through the following technical solutions: a detachable impeller assembly, comprising an impeller assembly and a mounting plate, the impeller assembly being fixedly sleeved with evenly distributed convex plates, and the impeller assembly being provided with evenly distributed drainage holes, the bottom end of the impeller assembly being fixedly sleeved with a connecting seat, the top end of the mounting plate being fixedly sleeved with a mounting seat matching the connecting seat, the bottom of the impeller assembly being fixedly sleeved with a limiting block located on the outside of the connecting seat, the mounting seat being provided with a groove matching the limiting block, a threaded column being threadedly connected in the impeller assembly, the top end of the threaded column extending to the outside of the impeller assembly and fixedly sleeved with a stud end, and the bottom end of the threaded column extending into the connecting seat and fixedly sleeved with an extrusion block, and the connecting seat being movably sleeved with evenly distributed fixing columns.

[0007] Furthermore, the mounting seat is provided with a through hole matching the fixing column, and the limiting block is provided with a fixing hole matching the fixing column. The through hole provided on the mounting seat can facilitate the penetration of the fixing column, and the fixing hole provided on the limiting block can cooperate with the fixing column to ensure the stability of the connection and fixation between the impeller assembly and the mounting seat after docking and fixing.

[0008] Furthermore, the outer ring of the impeller assembly is fixedly sleeved with a wheel edge, and the wheel edge matches the inner wall of the washing machine. The drainage holes are evenly distributed between the convex plates, and the wheel edge of the outer ring of the impeller assembly can assist in the adaptation between the impeller assembly and the inner wall of the washing machine, thereby facilitating the installation of the impeller assembly.

[0009] Furthermore, a cavity matching the extrusion block is provided inside the connecting seat, a slope is provided at the bottom of the extrusion block, and arc-shaped surfaces are provided at both ends of the fixing column. The extrusion block can contact and squeeze the outside of the fixing column during the downward movement, so that the fixing column passes through the through hole provided on the mounting seat and passes into the fixing hole in the limit block. The setting of the slope and the arc-shaped surface can facilitate the extrusion activity.

[0010] Furthermore, the outer fixing sleeve of the fixed column is provided with a limit plate, the connecting seat is provided with a slideway matching the limit plate, and a limit spring is connected between the connecting seat and the limit plate. The slideway in the connecting seat can facilitate the movement of the fixed column and the limit plate, and the fixed column and the limit plate can drive the limit spring to stretch after being squeezed by the extrusion block.

[0011] Furthermore, a gap is provided between the limit block and the connecting seat. When the top end of the connecting seat is completely withdrawn from the cavity in the connecting seat, the end of the connecting seat is embedded in the fixing hole on the limit block. The gap between the limit block and the connecting seat can be adapted to the external structure of the mounting seat, so that the fixing column passes through the mounting seat, the limit block and the connecting seat to achieve connection and fixation.

[0012] Furthermore, the bottom end of the stud end is fixedly sleeved with a limit plate located above the impeller assembly, and the lower part of the limit plate is fixedly sleeved with an anti-skid pad and an elastic ring. During the rotation of the threaded column, the limit plate can be driven to fit the upper surface of the impeller assembly and squeeze the anti-skid pad and the elastic ring. The anti-skid pad and the elastic ring are deformed after being squeezed and squeeze the limit plate under the action of their own elastic force, thereby preventing the limit plate and the threaded column from loosening during the operation of the impeller assembly.

[0013] The utility model provides a detachable impeller assembly, which has the following beneficial effects:

[0014] 1. The detachable impeller assembly, through the coordinated use of the mounting seat and the limit block as well as the fixed column and the extrusion block, enables the detachable impeller assembly to be assembled and fixed with the mounting seat, the connecting seat at the bottom end of the impeller assembly is sleeved in the mounting seat, the limit block is docked with the opening outside the mounting seat, and the extrusion block squeezes the fixed column, so that the fixed column passes through the through hole opened on the mounting seat and passes into the fixed hole in the limit block, thereby ensuring the stability of the connection and fixation between the impeller assembly and the mounting seat, and at the same time, the limit block is docked with the mounting seat to strengthen the connection relationship between the mounting seat and the impeller assembly, thereby ensuring the strength requirement for high-speed rotation during the overall working process of the assembly.

[0015] 2. The detachable impeller assembly uses a limit plate, an anti-skid pad and an elastic ring in combination, so that when the threaded column is rotated to complete the connection and fixation between the impeller assembly and the mounting seat, the threaded column drives the limit plate to fit with the upper surface of the impeller assembly during rotation, and squeezes the anti-skid pad and the elastic ring. The anti-skid pad and the elastic ring are deformed after being squeezed and squeeze the limit plate under the action of their own elastic force, thereby preventing the limit plate and the threaded column from loosening during the operation of the impeller assembly, thereby further improving the stability of the detachable impeller assembly after installation and fixation.
