Description

Technical Field

[0001] The utility model relates to the technical field of washing machines, in particular to a detachable cleaning inner barrel structure of a washing machine. Background Technique

[0002] In the prior art, the inner barrel of the washing machine is fixedly connected to the mounting shaft of the outer barrel through a plurality of bolts and nuts. Since each bolt and nut is in long-term contact with water, components such as oxygen and electrolytes in the water will chemically react with the metal surface, resulting in metal oxidation. This oxidation effect will gradually intensify over time, forming one or more rust layers. As the rust layer forms and thickens, the pressing degree between the mating surfaces of the bolts and nuts will gradually increase. This pressing not only enhances the intermolecular binding force but also significantly increases the frictional torque between the mating surfaces, thus increasing the difficulty of disassembling the bolts and nuts during the disassembly process, reducing the convenience of disassembling the inner barrel, and further affecting the cleaning efficiency of the inner barrel of the washing machine.

[0003] Therefore, there is an urgent need for a detachable cleaning inner barrel structure of a washing machine to solve the above problems. Content of the Utility Model

A plurality of fixing rings 206 are provided on the side of the inner cylinder body 104 away from the outer cylinder 103. A sealing gasket can be arranged on the side of the fixing ring 206 close to the inner cylinder body 104 to increase the tightening force against the bottom wall of the inner cylinder body 104. Two fixing holes 207 are formed in the inner walls of the fixing rings 206, and the two fixing holes 207 are arranged to match the fixing rod 203. An inclined angle is formed at one end of the fixing rod 203 close to the fixing hole 207, so as to provide a guiding function for the fixing rod 203 to enter the fixing hole 207. Each fixing tube 201 is provided with a driving assembly for driving the two fixing rods 203;

[0025] It should be noted here that: through the setting of the fixing assembly, by the mutual cooperation of the sealing assembly, the driving assembly and the moving assembly, the probability of water entering the fixing tube 201 is reduced, and further the risk of corrosion to the moving assembly is reduced, thus maintaining the smooth movement of the two fixing rods 203, further reducing the difficulty of disassembling the inner cylinder body 104, and thus improving the convenience of disassembling the inner cylinder body 104 and the cleaning efficiency of the inner cylinder body 104.

[0026] It should be noted that: as an existing mature technology, the internal structure of the washing machine has been fully disclosed and can be queried in relevant public patents and website videos. Here, only a simple drawing and description are made.

[0027] Please refer to Figure 5 , each fixing ring 206 in the figure is provided with a sealing assembly for sealing with the side wall of the fixing tube 201. The sealing assembly includes two annular sealing grooves 301 formed in the side wall of the fixing ring 206, and an annular rubber ring 302 is arranged in the two annular sealing grooves 301;

[0028] It should be noted here that: through the setting of the sealing assembly, the connection between the fixing ring 206 and the fixing tube 201 is sealed, thus reducing the probability of water entering the fixing tube 201, and further reducing the risk of corrosion to the moving assembly.

[0029] Please refer to Figure 5 , the sliding assembly in the figure includes a sliding groove 401 formed in the side wall of the fixing rod 203, a sliding plate 402 is slidably connected to the sliding groove 401, and one end of the sliding plate 402 is connected to the inner wall of the through hole 202;

[0030] It should be noted here that: through the setting of the sliding component, it provides guidance and limit functions for the movement of the fixed rod 203.

[0031] Working principle: When installing the inner cylinder body 104, first align the multiple positioning holes 205 on the inner cylinder body 104 with the fixed tubes 201 on the connecting ring 108, then push the inner cylinder body 104 to move closer to the outer cylinder 103, and make the fixed tubes 201 insert into the positioning holes 205. When one end of the inner cylinder body 104 abuts against one side of the connecting ring 108, stop pushing the inner cylinder body 104;

[0032] After the inner cylinder body 104 abuts against the side wall of the connecting ring 108, sleeved the fixing ring 206 onto the side wall of the fixed tube 201, and make one side of the fixing ring 206 abut against the bottom wall of the inner cylinder body 104. Then, by rotating the fixing ring 206, make the fixing holes 207 on the fixing ring 206 align with the through holes 202 on the fixed tube 201. More optimally, marking lines can be engraved on the fixing holes 207 and the through holes 202 to facilitate the alignment convenience of the fixing holes 207 and the through holes 202. After aligning the fixing holes 207 with the through holes 202, use the driving component to push the two fixed rods 203 to move away from each other. During the continuous movement of the two fixed rods 203 away from each other, it will push the two fixed rods 203 to insert into the fixing holes 207 and abut against the bottom wall of the fixing holes 207. Thus, under the abutting action of the fixed rods 203, the fixing of the fixing ring 206 is realized, and further the installation of the inner cylinder body 104 is carried out;

[0033] And through the sealing component arranged on the inner wall of the fixing ring 206, the connection between the fixing ring 206 and the fixed tube 201 can be sealed, thereby reducing the probability of water entering the fixed tube 201, further reducing the risk of corrosion to the moving component, thus maintaining the smooth movement of the two fixed rods 203, reducing the difficulty of disassembling the inner cylinder body 104, and further improving the convenience of disassembling the inner cylinder body 104 and the cleaning efficiency of the inner cylinder body 104;

[0034] When it is necessary to disassemble and clean the inner cylinder body 104, the upper cover 102, the outer cylinder 103, the seal of the inner cylinder body 104 near the upper cover 102 end, and the agitator 105 can be removed in sequence, then the moving component can be exposed, and thus the inner cylinder body 104 can be disassembled by using the moving component and the driving component, further facilitating the cleaning of the inner cylinder body 104.
