[0002] In order to overcome the problems of water saving and preventing secondary pollution in fully automatic pulsator washing machines, the industry has developed a water-saving washing machine, that is, a hole-free washing barrel washing machine. 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 structural 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 an inner drum has a poor sealing effect and a short service life. The dirty water in the inner drum must be discharged before dehydration. How to provide a deceleration clutch to effectively operate the discharge of water in the inner drum and close it in time is a technical problem that we currently need to solve.

[0019] Combination Figure 1-Figure 5, which is a schematic diagram of the principle structure of a water switch opening device for a deceleration clutch of a water-saving washing machine of the present invention, comprises a mounting plate 21, a hinge plate 16 fixedly mounted on the deceleration clutch mounting plate 21, a shift fork rod 12, a return spring and a linear shaft 11, wherein the shift fork rod 12 is rotatably mounted on the hinge plate 16 through a rotating shaft 18, a return spring is arranged between one end of the shift fork rod 12 and the mounting plate 21, and is connected to an external power component 17 through a pull rope 20, and the other end is connected to the linear shaft 11; the other end of the shift fork rod 12 is divided into two symmetrical branches, each branch having a plurality of symmetrical branches. A slide groove 23 is provided on each branch, and is slidably connected to the linear shaft 11 through the slide groove 23; a neck-shaped groove is provided at the sliding fit between the linear shaft 11 and the slide groove 23 of the fork rod 12; a linear bearing seat 10 is also symmetrically installed on the mounting plate 21 relative to the axis, and the linear shaft 11 is axially movably installed in the linear bearing seat 10; a top-sealed bellows 9 is sheathed on the outside of the linear bearing seat 10, and the other end of the linear shaft 11 is connected to the top of the bellows 9; the power component 17 is a second-speed traction motor with a washing conversion function.

[0020] When the washing machine finishes washing and drains water, the traction motor of the second gear stroke starts to work. At this time, the working motor of the washing machine does not work. When the motor is in the first gear, it is in the disengaged state. When the second gear is in place, the fork rod 12 is pulled to rotate around the rotating shaft 18 through an angle, and the slide groove 23 at the other end of the fork rod 12 drives the linear shaft 11 to move up one end distance to drain water; after the water is drained, the traction motor loses power and quickly resets. At this time, the traction motor only works in the first gear stroke, driving the clutch mechanism from the washing state to the dehydration state, but will not touch the drainage fork rod 12. At this time, the working motor of the washing machine starts to work under the control of the program, driving the impeller, the inner drum and the clothes to dehydrate at high speed. The water rises along the wall of the inner drum and is thrown out from the water-throwing holes at the bottom of the balance ring to dry the clothes.

[0021] When the power component is a dedicated traction motor, the main clutch structure for washing and dehydration conversion remains the traditional clutch structure, including a common clutch with a single ratchet, a hand-rubbed clutch with double ratchets, and a dual-power clutch; the auxiliary clutch structure is a power structure specially added to realize the drainage function of the hole-free inner barrel washing machine. A crank linear moving structure is added to the mounting plate of the original clutch to realize the clutch function of the drainage structure of the hole-free inner barrel washing machine. The specific structure and principle are as follows: the rubber valve plug is a normally closed structure under the action of the reset spring and its own weight, and the water in the washing barrel is retained; when drainage is required, the dedicated power component works under the action of the washing machine program, driving the fork rod 12 to push the annular push plate up, and the guide column and the rubber valve plug connected to the annular push plate move up, and the water is discharged from the drainage hole; when the external force disappears, under the action of the reset spring, the annular push plate moves down and resets, and the rubber valve plug resets and returns to a closed state.

[0022] The shift fork rod 12 and the linear shaft 11 may also be connected via a pin.
