Its structure is that the lower part of the inner drum is designed as an integral whole, and there is a circle of water-spraying holes only near the balance ring of the barrel wall, and there are no holes in other parts. During the washing process of this structure washing machine, there is water in the inner drum, and there is no water between the inner drum and the box body, which can solve the problems of water saving and preventing secondary pollution. However, the existing water switch device with inner drum has poor sealing effect and short service life. The dirty water in the inner drum must be discharged before dehydration, but it must be closed for rotation during washing and dehydration. How to effectively discharge the water in the inner drum is a technical problem that we currently need to solve. Summary of the invention

[0005] There are a plurality of guide holes and drainage holes, which are evenly and staggeredly arranged on the circumference of the cross section of the inner cylinder flange relative to the axis center line.

[0006] The diameter of the drainage hole is 10-50 mm, and the diameter of the guide hole is 5-10 mm.

[0007] The guide column and the rubber valve plug form a unit and are fastened together as a whole. The guide column and the guide hole are movably connected in a sliding fit. The outer diameter of the rubber valve plug is larger than the diameter of the drainage hole.

[0008] The clutch plate is an integral annular push plate, and the annular push plate is connected to each rubber valve plug.

[0009] The clutch plate is a baffle, and there are a plurality of baffles, which are individually connected to each rubber valve plug.

[0010] A balance ring is arranged at the top of the inner cylinder, and a circle of water-throwing holes is arranged on the inner cylinder wall near the lower end of the balance ring.

[0011] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows: the product of the present invention can quickly discharge the washing water in the inner drum by arranging a water sealing device on the inner drum flange, and then close the water sealing component for dehydration, which is simple and convenient to operate and has good effect.

[0016] Combination Figure 1-Figure 3 , which is a schematic diagram of the principle structure of a water switch water sealing device of a multifunctional inner drum of a water-saving washing machine of the present invention, comprising an inner drum 2 with the functions of holding water, washing and dehydrating, wherein the inner drum 2 is connected to an inner drum flange 5 at the bottom, wherein a drainage hole 14 and a guide hole 6 are provided on the inner drum flange 5, wherein a rubber valve plug 15, a reset spring 13 and a clutch plate 8 are provided on the drainage hole 14 and the guide hole 6, wherein the rubber valve plug 15 passes through the guide hole 6 through the guide column 7 and is installed on the clutch plate 8, wherein the reset spring 13 is provided between the inner drum flange 5 and the clutch plate 8; wherein the guide hole 6 and the drainage hole 14 are provided with a plurality of holes, wherein the inner drum flange 5 is provided with a plurality of holes ... the guide hole 6 through the guide column 7 and the guide hole 6 through the guide column 7 and the guide hole 6 through the guide column 7 and the guide hole 6 through the guide column 7 and the guide hole 6 through the guide column 7 and the guide hole 6 through the guide column 7 and the guide hole 6 through the guide column 7 and the 5 are evenly spaced and staggered on the circumference of the cross section relative to the axis center line; the diameter of the drainage hole 14 is 30 mm, and the diameter of the guide hole 6 is 6 mm; the guide column 7 and the rubber valve plug 15 form a unit and are fastened together as a whole, the guide column 7 and the guide hole 6 are movably connected with each other in a sliding fit, and the outer diameter of the rubber valve plug 15 is larger than the diameter of the drainage hole 14; the clutch plate 8 is an integral annular push plate, which is connected to each rubber valve plug 15; the top of the inner cylinder 2 is provided with a balance ring 1, and a circle of water-throwing holes 3 is provided on the inner cylinder wall near the lower end of the balance ring 1.

[0017] The clutch plate 8 may also be a baffle, and there are a plurality of baffles, which are individually connected to each rubber valve plug 15 respectively.

[0018] Working principle: The rubber valve plug 15 is in a normally closed structure under the action of the reset spring 13 and its own weight. The water in the washing tub, i.e., the inner drum 2, is retained. Under the action of external force, the annular push plate is pushed up, and the guide column 7 and the rubber valve plug 15 connected to the annular push plate move up, and the water is discharged from the drain hole 14; when the external force disappears, under the action of the reset spring 13, the annular push plate moves down and resets, and the rubber valve plug 15 resets and returns to a closed state.

[0019] Working process: After the washing machine is turned on, it enters the water inlet state, the rubber valve plug 15 is in the closed state, the water in the inner drum 2 is kept, the water inlet is finished, and it enters the washing state. After the washing is finished, the external force pushes the annular push plate upward, the rubber valve plug 15 is in the open state, and the water is discharged from the drain hole 14. After the water is drained, the external force disappears, and under the action of the reset spring 13, the annular push plate moves down and returns to the closed state. At this time, it enters the dehydration process, and the water is thrown out from the water-throwing hole 3 at the bottom of the upper balance ring 1 under the action of centrifugal force.
