- the balance ring on the inner cylinder contacts the outer cylinder cover, and the protrusion on the balance ring and the inner side of the outer cylinder cover are convex. Blocking each other prevents the inner cylinder from rotating.
- the rotation of the pulsator shaft 8 only drives the pulsator 12 in the inner cylinder to rotate.
- This embodiment has a simple structure and is convenient to set up.
- the height of the protective cover after installation is At least the top end is located in the sealed cavity of the inner buoyancy chamber 502 to prevent the washing water from contacting the pulsator shaft between the crown gear 10 and the female gear 9 and the top end of the protective sleeve, thereby preventing the impurities contained in the washing water from sticking. Attached to the pulsator shaft and into the protective sleeve to ensure the normal lifting of the inner cylinder and extend the service life of the skeleton oil seal.
- the height of the spacer 505 is adjusted to ensure that the sealing cavity formed by the spacer 505 can cover the top end of the protective sleeve 1108 when the inner cylinder is floated to the washing position. Therefore, the end face of the spacer rib needs to be higher than the end face of the inner cylinder buoyancy chamber 501 to increase the air in the inner buoyancy chamber.
- the two sealed chambers of the buoyancy chamber 501 and the inner buoyancy chamber 502 at the bottom of the inner cylinder simultaneously push the inner cylinder 5 to float, and the water permeable hole 504 circulates the washing water between the inner cylinder and the outer cylinder, thereby reducing The resistance of the inner cylinder is received.
- the top end of the protective sleeve 1108 is located in the sealing cavity of the inner buoyancy chamber and protrudes out of the washing water surface, thereby preventing the washing water from being protected. The top of the sheath enters the protective sleeve to achieve a waterproof effect.
- the washing machine of the present scheme adopts a shock absorbing manner of a shock absorbing boom
- the shock absorbing hanger 14 includes a boom 1401, and the upper ball seat 1402 at the top end of the boom is connected in series with the lower ball on the boom.
- the seat 1403, the spring 1404, and the spring seat 1405 are provided with a hanger corresponding to the concave and convex portion of the upper ball seat 1402 in the top of the casing 1 of the washing machine, and a concave portion corresponding to the lower spherical seat portion is disposed on the side surface of the outer cylinder 5
- the shock absorbing seat 401 wherein the hanging seat and the damper seat respectively have a fracture having a diameter larger than the diameter of the hanger 1401, and the contact surface of the suspension seat and the upper ball seat and the contact surface of the shock absorbing seat and the lower ball seat respectively are curved surfaces corresponding to the concave and convex portions
- the boom 1401 is cut into the fracture, and the upper and lower seats are respectively attached to the suspension and the shock absorber under the gravity of the inner and outer cylinders, and the upper and lower balls are fitted together.
- the seat seals the break, preventing the boom from coming out.
- a tapered tube 1406 protruding outward is arranged at the shaft hole of the lower ball seat and the damper seat, and the diameter of the tapered tube is larger than the diameter of the fracture, so that only The distance between the ball seat and the damper seat does not exceed the length of the conical tube, and the boom will not be dislodged from the fracture.
- a shock absorbing hanger is respectively installed on the four corners of the washing machine box, and the outer cylinder is in a relatively floating equilibrium position in the box body under the pulling force of the shock absorbing boom, and the outer cylinder and the box body are prevented. Collision.
- the working process of the washing machine of the present scheme is as follows: The laundry within 1 kg of the washing amount to be washed is put into the washing machine, the washing machine starts the washing process under the control of the automatic washing program, the water is filled in the washing machine, and the buoyancy chamber at the bottom of the inner cylinder during the water filling process And the buoyancy chamber pushes the inner cylinder to rise along the pulsator shaft under the buoyancy of water.
- the inner concave gear at the bottom of the inner cylinder is separated from the outer convex gear on the pulsator shaft, and the inner cylinder rises to a certain height, and the inner cylinder balances at the top.
- the ring is in contact with the outer cylinder cover at the top of the outer cylinder, and the protrusions of the two are in contact with each other.
- the washing starts.
- the motor shaft of the motor directly drives the pulsator shaft to rotate, thereby driving the pulsator to wash the laundry.
- the inner cylinder is in a relatively static state under the convex barrier of the balance ring and the outer cylinder cover, and the protective sleeve on the bearing seat extends into the inner buoyancy chamber, thereby avoiding the stain of the washing water entering the protective sleeve and the washing water.
- the washing machine drains. After the inner cylinder loses buoyancy, it descends along the pulsator shaft. Finally, the concave gear on the inner cylinder meshes with the convex gear on the pulsator shaft. At this time, the dehydration program is started, and the convexity fixed on the pulsator shaft is fixed. The gear rotates the inner cylinder by the concave gear to achieve dewatering of the clothes.
