[0002] The wet washing machine inner container is the core component of the wet washing machine, which is used to hold the cleaned objects, water and detergent, and remove the dirt attached to the cleaned objects through rotation or water flow during the washing process.

During the test process, simulated clothes or test cloth are added, and oil stains and solid impurities are generated during the simulation washing process. After the test is completed, the total amount of test wastewater is small, so it is not convenient to discharge and subsequent treatment, and the oil stains and impurities will adhere to the wet washing machine inner container, so the wet washing machine inner container needs to be washed twice, which wastes water resources.

After the cleaning and dehydration are completed, the clothes are supported, the residual water stains are continuously removed, and the residual water accumulated at the bottom is removed, so that the problem of difficult removal of a small amount of water is solved. However, the above patent application still does not solve the problem of oil stains and impurities adhering to the inner container, and the inner container still needs to be cleaned twice to remove the oil stains and impurities adhering to the inner container, so the problem of water resource waste still exists.

The end of the push rod 64 can be fitted in the arc-shaped groove.

[0057] In the initial state, the push rod 64 is located in the annular space between the inner container 3 and the outer cylinder 2. When the inner container 3 moves upward, the second outer edge 33 drives the limiting wheel 52 and the limiting seat 51 to move upward. During the upward movement of the limiting seat 51, the limiting seat 51 abuts against the second rotating ring 94 and pushes the second rotating ring 94 to move upward. The rotating rod 93 moves upward synchronously with the second rotating ring 94. The rotating rod 93 moves upward relative to the fixed seat 92. The sliding block slides in the spiral sliding groove 931 and pushes the rotating rod 93 to rotate. The push rod 64 moves synchronously with the rotating rod 93, so that the push rod 64 rotates around the axis of the rotating rod 93 while moving upward. When the push rod 64 moves upward to the limit, the end of the push rod 64 can extend into the arc-shaped groove of the limiting rod 10.

[0058] The inner side wall of the second rotating ring 94 is provided with a gear slot. The fixed shaft 53 is fixedly provided with a rotating gear 11. When the limiting seat 51 abuts against the second rotating ring 94, the rotating gear 11 can engage with the second rotating ring 94 through the gear slot. When the inner container 3 rotates, the second outer edge 33 can drive the limiting wheel 52 to rotate. The rotating gear 11 rotates synchronously with the limiting wheel 52. The rotating of the rotating gear 11 can drive the second rotating ring 94 to rotate around its axis. The rotating rod 93 rotates synchronously with the second rotating ring 94 and drives the first rotating ring 91 to rotate around its axis through the fixed seat 92. The rotation of the first rotating ring 91 drives the push rod 64 to rotate. The push rod 64 can scrape off the floating matter at the liquid surface during the rotation.

[0059] The outer side wall of the outer cylinder 2 is provided with a collecting groove 22 at the top end. The side wall of the collecting groove 22 is provided with a drain hole. The push rod 64 can push the floating matter into the collecting groove 22 during the process of pushing the floating matter.
