Example one

In the embodiment of the invention, in order to discharge water flow after clothes in the inner barrel 1 of the washing machine are separated and realize that the inner barrel 1 is sealed and filled with water to carry out normal washing in the working process of the washing machine, the following settings are carried out:

as shown in fig. 1 to 4, in the present embodiment, a washing machine is described, in which a washing machine inner cylinder 1 is a container whose inner cylinder opening 101 is closed by a door cover 4, at least one water outlet 10 is provided on a bottom 102 of the inner cylinder, a sealing valve 9 that moves along the inner cylinder bottom 102 in a radial direction to open and close is provided at the water outlet 10, and a valve body 92 of the sealing valve 9 moves along the inner cylinder bottom 102 in a radial direction to a central direction under centrifugal force when the inner cylinder 1 rotates at a high speed to open the water outlet 10 provided on the inner cylinder bottom 102.

In this embodiment, the outer periphery of the inner cylinder bottom 102 is provided with a plurality of water outlets 10 arranged at equal intervals and angles, each water outlet 10 is correspondingly provided with a sealing valve 9, and the valve body 92 of the sealing valve 9 moves along the inner cylinder bottom 102 in the radial direction under the action of the limiting structure and the high-speed rotation centrifugal force of the inner cylinder 1, so as to correspondingly open the water outlets 10. Preferably, the water outlets 10 are arranged symmetrically with respect to the center of the inner cylinder bottom 102, so that the center of gravity of the inner cylinder bottom 102 is at the center, thereby preventing the inner cylinder 1 from being eccentric.

In this embodiment, the sealing valve 9 includes a valve body 92, the valve body 92 is connected to the weight block 91 through a connecting rod, the connecting rod 93 and the weight block 91 are disposed at two opposite sides of the center of the inner cylinder bottom 102, the weight block 91 moves radially outward along the inner cylinder bottom 102 under the action of centrifugal force when the inner cylinder 1 rotates at a high speed, and the connecting rod 93 pulls the valve body 92 to move toward the center of the inner cylinder bottom 102 to open the corresponding water outlet 10. The sealing valve 9 is arranged on the inner cylinder bottom 102 of the washing machine, so that centrifugal force acts on the balancing weight 91 when the inner cylinder 1 rotates at high speed, the balancing weight 91 moves towards the periphery direction of the inner cylinder 1, and the valve body 92 on the opposite side is further pulled to move towards the center direction of the inner cylinder bottom 102, and the purpose of opening the water outlet 10 arranged on the inner cylinder bottom 102 by utilizing the centrifugal force when the inner cylinder 1 rotates at high speed is achieved.

Preferably, the weight of the weight block 91 is greater than the weight of the valve body 92, so that the centrifugal force applied to the connection structure of the weight block 91 and the valve body 92 moves toward the center of the inner cylinder bottom 102 in the direction of the valve body 92. Further preferably, in order to improve the action of the centrifugal force, the weight of the weight block 91 is greater than 2 times of the weight of the valve body 92, so that the valve body 92 can reliably move towards the center of the inner cylinder bottom 102 under the action of the centrifugal force, and the influence of the weight block 91 and the friction force can be overcome.

In this embodiment, the connecting rod passes through the center of the inner cylinder bottom 102 and extends along the radial direction of the inner cylinder bottom 102, two ends of the connecting rod 93 are respectively fixedly connected with the counterweight 91 and the valve body 92 of the sealing valve 9, the counterweight 91 and the valve body 92 of the sealing valve 9 are respectively arranged on two opposite sides relative to the center of the inner cylinder bottom 102, so that the counterweight 91 and the valve body 92 respectively generate displacements in opposite directions under the action of centrifugal force, but because the weight of the counterweight 91 is greater than the weight of the valve body 92, the counterweight 91 pulls the valve body 92 through the connecting rod to move together towards the direction of the valve body 92 close to the center of the inner cylinder bottom 102, and the valve body 92 opens the water outlet 10 under the action of centrifugal force when the inner cylinder 1 rotates at a high speed; and each water outlet 10 is arranged close to the periphery of the inner cylinder bottom 102, so that when the washing machine dehydrates, water flowing along the side wall of the inner cylinder 1 is discharged outside through the water outlets 10 arranged at the periphery of the inner cylinder bottom 102, all dehydrated water in the dehydration procedure of the washing machine is discharged outside, and the condition of retained water in the inner cylinder 1 is avoided.

In this embodiment, the valve body 92 of the sealing valve 9 is connected to the inner cylinder bottom 102 through an elastic restoring member, so as to apply an elastic force to the valve body 92 to push the valve body 92 to close the corresponding water outlet 10, and when the inner cylinder 1 rotates at a high speed, the centrifugal force overcomes the elastic force of the elastic restoring member to move the valve body 92 and open the water outlet 10. The elastic restoring piece is arranged on the sealing valve 9 to ensure that the valve body 92 is in a closed position in an initial state, so that the valve body 92 blocks the water outlet 10; meanwhile, after the sealing valve 9 is opened by the centrifugal force and the washing machine stops executing the dehydration program, the valve body 92 is pulled by the elastic restoring piece to restore the valve body 92 to the closed position of the initial state, so that the valve body 92 blocks the water outlet 10, and when the washing machine executes the washing program and the rinsing program, the inner barrel 1 is a closed container to avoid the condition that the washing water or the rinsing water flows out.
