Description

Technical Field

[0001] This utility model belongs to the field of washing machine impeller technology, specifically a washing machine inner drum impeller. Background Technology

[0002] A top-loading washing machine has a disc-shaped impeller at the bottom of the tub with protruding ribs. Driven by the impeller, the water flow inside the tub forms a vortex that rotates clockwise and counterclockwise, causing the fabric to rotate and tumble, thus removing dirt from the clothes. Its structure is relatively simple, easy to maintain, and has a high washing efficiency, but it causes greater wear and tear on clothes and uses more water.

[0003] A search revealed that patent CN219861984U discloses a washing machine pulsator assembly that is easy to assemble. This invention includes a pulsator body with a circumferential array of agitating ribs on its surface. A protrusion is located at the center of the pulsator body's surface, with a through hole at the center of the protrusion. A fixing bolt is threaded into the through hole. A gripping part is located on the surface of the protrusion, along with a gripping component for gripping the gripping part. This invention, by providing the gripping part and its matching gripping component, allows the gripping component to be inserted into the washing tub after removing the fixing bolt from the pulsator body. The gripping component then grasps the gripping part, allowing the pulsator body to be extended directly from the washing tub. This is convenient and quick. Furthermore, because the gripping component is retractable, it can reach the bottom even if the washing tub is deep.

[0004] Analysis of the above technical solutions reveals that while the pulsator body can be directly extracted from the washing tub using the gripping component, this requires first removing the bolts on the pulsator with an electric screwdriver. This necessitates the use of different tools, leading to a lengthy disassembly process and reduced efficiency in repair and maintenance. Therefore, we provide a washing machine inner drum pulsator solution to address these issues. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-7As shown, this embodiment proposes a washing machine inner drum impeller, including an impeller body 1 and a protrusion 2 disposed in the middle of the impeller body 1. A bolt is provided in the middle of the protrusion 2, which fixes the protrusion 2 to the drive shaft of the washing machine. When the impeller body 1 needs to be disassembled, only the bolt needs to be removed from the drive shaft. Two opposing positioning grooves 11 are formed on the surface of the protrusion 2, and each positioning groove 11 is provided with a locking groove 12. A positioning plate 5 is provided above the protrusion 2. The positioning plate 5 is separate from the protrusion 2. The positioning plate 5 is only used when the impeller body 1 needs to be disassembled. The positioning plate 5 is provided with a positioning mechanism for engaging with the protrusion 2. A screwdriver 3 is inserted through the middle of the positioning plate 5. Furthermore, the screwdriver 3 is located in the middle of the positioning mechanism. With the above-mentioned structure, the positioning mechanism can be used to easily connect the positioning plate 5 and the protrusion 2, which facilitates the subsequent removal of the protrusion 2 from the washing machine. Then, the screwdriver 3 is used to loosen the bolt in the middle of the protrusion 2. Finally, the pulsator body 1 can be removed from the washing machine by directly pulling the positioning mechanism or the screwdriver 3. There is no need to use different tools to replace them, making the operation process faster. The screwdriver 3 can be set to electric, so that personnel can easily remove the bolt in the middle of the protrusion 2 without manual tightening. The mechanics, parts and equipment in this device all adopt conventional models in the existing technology, which will not be described in detail here.

[0024] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, the positioning mechanism includes a sleeve rod 4, which is sleeved on the surface of the screwdriver 3. The positioning plate 5 has two opposing sliding grooves 14. The inner wall of each sliding groove 14 is fixedly connected to a guide rod 17. Each guide rod 17 is sleeved with a retaining plate 6 and a tension spring 16. The two ends of the tension spring 16 are respectively fixedly connected to the surface of the retaining plate 6 and the inner wall of the grip rod 15. The bottom ends of the two retaining plates 6 are respectively adapted to the two retaining grooves 12. The bottom end of the sleeve rod 4 is hinged to two opposing connecting rods 8, and the bottom ends of the two connecting rods 8 are respectively hinged to the top ends of the two retaining plates 6. With the above structure, the positioning plate 5 and the protrusion 2 can be quickly connected. Simply insert the two retaining plates 6 into the two positioning grooves 11 until the bottom ends of the two retaining plates 6 are automatically engaged with the two retaining grooves 12. Then, loosen the bolt in the middle of the protrusion 2 with the screwdriver 3. Finally, pull the sleeve rod 4 to remove the impeller body 1 from the washing machine. The operation is faster.

[0025] like Figure 1 , Figure 3 and Figure 5As shown, two opposing grips 15 are fixed to the top of the sleeve rod 4. With the grips 15, it is easy for personnel to push the top of the sleeve rod 4 downward, thereby releasing the locking limit of the protrusion 2 and ensuring that the positioning plate 5 can be removed normally. In addition, the grips 15 also facilitate the removal of the impeller body 1 from the washing machine, making it convenient for personnel to hold.

[0026] like Figure 5 and Figure 7 As shown, several anti-slip protrusions are fixedly connected to the inner wall of the top of the sleeve rod 4 and the inner wall of the positioning plate 5. The screwdriver 3 is in contact with the anti-slip protrusions. The bottom end of the screwdriver 3 is fixedly connected to the limiting plate 13, which is located on the bottom surface of the positioning plate 5. The anti-slip protrusions prevent the screwdriver 3 from slipping in the middle of the sleeve rod 4 and the positioning plate 5, thus increasing the contact friction between the screwdriver 3 and the sleeve rod 4 and the positioning plate 5. The screwdriver 3 can only be moved normally when the operator pushes or pulls it downwards. The limiting plate 13 prevents the bottom end of the screwdriver 3 from being pulled out of the positioning plate 5, thus making the screwdriver 3 and the positioning plate 5 a single unit. In addition, when removing the impeller body 1, the screwdriver 3 can be pulled upwards directly to remove the impeller body 1, improving the flexibility of the device.

[0027] like Figure 1 , Figure 3 , Figures 5 to 7 As shown, the surface of the protrusion 2 has two opposing mounting grooves 10. Each mounting groove 10 is elastically hinged with a baffle 9 to cover the bolt in the protrusion 2. A torsion spring is provided at the hinge between the baffle 9 and the mounting groove 10. Therefore, when the baffle 9 is pressed open, it has the characteristic of automatic reset. This ensures that the baffle 9 will not pop open during normal use of the impeller body 1 and will always be in contact with the protrusion 2. The bottom surface of the positioning plate 5 is fixedly connected to two opposing insert plates 7. The bottom end of the insert plate 7 slides in the mounting groove 10 and presses against one end of the baffle 9. With the above structure, when the positioning plate 5 is directly above the protrusion 2 and moves downward, the bottom ends of the two insert plates 7 are aligned with the two mounting grooves 10 and inserted. During this process, one end of the two baffles 9 is pressed by the bottom end of the corresponding insert plate 7 and rotated 90°, so that the bolt in the protrusion 2 is properly exposed, so as to ensure that the bolt in the middle of the protrusion 2 can be loosened by the screwdriver 3 later.

[0028] The working principle and usage process of this utility model are as follows: When it is necessary to remove the impeller body 1 from the washing machine, first align the bottom ends of the two insert plates 7 with the two mounting slots 10 and insert them. During this process, one end of the two baffles 9 is squeezed and rotated 90° by the bottom ends of the corresponding insert plates 7, so that the bolts in the protrusion 2 are exposed normally. Then, the two locking plates 6 will be inserted into the two positioning slots 11 until they are automatically locked into the slots 12, thus ensuring a quick connection between the positioning plate 5 and the protrusion 2. Then, push the screwdriver 3 down and use the screwdriver 3 to loosen the bolts in the protrusion 2. Finally, pull the screwdriver 3 or the handle 15 upward to remove the impeller body 1 from the washing machine. The operation is more convenient and flexible. When it is necessary to separate the positioning plate 5 from the protrusion 2, simply push the sleeve 4 down so that the two connecting rods 8 push the two locking plates 6 away from each other, so that the two locking plates 6 are away from the two slots 12. Then, pull the screwdriver 3 upward to separate the positioning plate 5 from the protrusion 2, so as to ensure the replacement of the impeller body 1 later.
