The water-saving washing machine drainage device is provided with a water dispenser 3 on the wall of the inner cylinder 1, a drainage groove 5 is arranged in the water dispenser 3, and a drainage hole 4 is arranged on the outer surface of the water dispenser 3, so that the washing water in the inner cylinder 1 is discharged through the drainage hole 4 and the drainage groove 5, and the discharge of water is controlled by opening and closing the drainage valve 6, and then the washing water is discharged out of the washing machine body through the drainage structure arranged outside the inner cylinder 1 of the washing machine. The inner drum 1 of the washing machine of this design is mainly used for holding and washing clothes. The wall of the inner drum 1 adopts a hole-free integral closed structure. During the washing process, the washing water only exists inside the inner drum 1, and there is no washing water between the inner drum 1 and the outer drum 2. Therefore, the water intake only needs to meet the requirements of washing clothes, thereby achieving the purpose of water saving. In addition, the washing water only exists in the inner drum 1, and the washing water can be discharged from the washing machine in time, which can prevent bacteria from growing in the washing machine, contaminating clothes, and causing secondary contamination of clothes.

[0026] Further, an inner slider 16 and an outer slider 15 are provided between the inner drum 1 and the outer drum 2. The inner slider 16 and the outer slider 15 can rotate relative to each other and are connected to each other. The outer slider 15 can move under the action of the driving device. The movement of the outer slider 15 can drive the inner slider 16 to move. The movement of the inner slider 16 can open or close the drain valve 6. Specifically, the inner slider 16 is connected to the drain valve 6, and the outer slider 15 is connected to the traction motor 22 provided on the outer drum 2. The outer slider 15 slides toward the outside of the washing machine through the traction action of the traction motor 22, thereby driving the inner slider 16 connected thereto to slide toward the outside of the washing machine, thereby opening the drain valve 6 connected to the inner slider 16. By providing the inner slider 16 and the outer slider 15 that can rotate relative to each other and are connected to each other between the inner drum 1 and the outer drum 2, the purpose of controlling the drain valve 6 installed on the rotating inner drum 1 to drain water is achieved on the stationary outer drum 2.

[0027] Specifically, the inner slider 16 and the outer slider 15 are connected through the bearing 17, the inner slider 16 is connected to the inner ring of the bearing 17, and the outer slider 15 is connected to the outer ring of the bearing 17. Preferably, the inner slider 16 is interference-connected with the inner ring of the bearing 17, and the outer slider 15 is interference-connected with the outer ring of the bearing 17. By virtue of the relative rotation of the inner and outer rings of the bearing 17, the purpose of controlling the drainage of the drainage valve 6 installed on the rotating inner cylinder 1 by the stationary outer cylinder 2 is achieved.

[0028] Furthermore, the drain valve 6 includes a drain valve housing 9 and a drain valve core 7, a return spring 8 is provided between the drain valve core 7 and the drain valve housing 9, and the drain valve core 7 is connected to the inner slider 16 via an inner traction line 10. The drain valve core 7 can slide toward the center of the washing machine under the pulling force of the inner slider 16 and the inner traction line 10 through the action of the inner slider 16, the inner traction line 10 and the return spring 8, thereby opening the drain valve 6; and slide in the opposite direction under the elastic restoring force of the return spring 8, thereby closing the drain valve 6; thereby realizing the conversion of the washing machine's draining, washing, dehydration and other working conditions.

[0029] Furthermore, a bracket 13 is provided on the outer end surface of the bottom of the outer cylinder 2, and an opening is provided on the bracket 13. A guide sleeve 14 is provided at the opening of the bracket 13. The guide sleeve 14 is concentrically arranged with the inner cylinder shaft 19. An axially sliding outer slider 15 is provided in the guide sleeve 14. The outer slider 15 is connected to the inner slider 16 through a bearing 17. The inner slider 16 is connected to an inner traction wire 10 passing through a positioning sleeve 18 arranged in the inner cylinder shaft 19. A positioning sleeve 18 is arranged in the inner cylinder shaft 19. The inner traction wire 10 is connected to the inner slider 16 after being led out through the inside of the positioning sleeve 18. The outer slider 15 is connected to one end of an outer traction wire 20, and the other end of the outer traction wire 20 is connected to a traction motor 22 arranged on the outer cylinder 2. Preferably, the outer traction wire 20 is connected to the traction motor 22 through a sheath 21.

[0030] The guide sleeve 14 is connected to the traction motor 22 provided on the outer cylinder 2 through the sleeve 21. The provision of the guide sleeve 14 can make the outer slider 15 and the inner slider 16 slide more smoothly, making the control of the drainage device more precise. The provision of the positioning sleeve 18 can further prevent the inner traction line 10 from being entangled, knotted or shaken when the inner cylinder 1 rotates at a high speed for dehydration.

[0031] Furthermore, a pulley connected to an external motor is installed on the outer circle of the inner cylinder shaft 19.

[0032] Furthermore, the water displacer 3 is a protruding structure arranged on the inner wall of the inner tube 1 , at least one water displacer 3 is arranged, and the water displacer 3 corresponds to the legs of the tripod 11 one by one; the drain valve 6 is fixed on the tripod 11 .

[0033] Furthermore, the drainage groove 5 is arranged obliquely along the wall of the inner tube 1, and one end of the drainage groove 5 close to the bottom of the inner tube 1 is inclined toward the outside of the inner tube 1. By arranging the drainage groove 5 obliquely, the bottom of the inner tube 1 is arranged in an open shape, which facilitates the water flow to the drainage valve 6 at the bottom of the inner tube under the action of centrifugal force during drainage and dehydration.

[0034] During washing, the drain valve 6 is in the closed state, the inner drum 1 rotates forward and reversely, the inner traction line 10, the positioning sleeve 18, the inner slider 16, and the inner ring of the bearing 17 rotate synchronously with the inner drum 1, and the outer ring of the bearing 17, the outer slider 15 and the outer traction line 20 are relatively stationary.

[0035] When draining or dehydrating, the traction motor 22 pulls the outer traction line 20, and pulls the inner traction line 10 through the connection between the outer slider 15, the bearing 17 and the inner slider 16, thereby pulling the drain valve core 7 inward along the radial direction of the inner tube 1 to open the drain valve 6. At this time, due to the action of the inner and outer rings of the bearing 17, the inner slider 16, the outer slider 15, the inner traction line 10, and the outer traction line 20 are still separated in the circumferential direction, ensuring that the inner traction line 10 and the outer traction line 20 will not be entangled when the inner tube 1 rotates at high speed for dehydration.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
