The present disclosure relates to a locking mechanism of an inner tub and a washing machine. The locking mechanism comprises a locking rod capable of reciprocating along an axial direction, a slideway for the movement of the locking rod and a driving unit for driving the locking rod to move, the driving unit comprises a link, a crank and a rotating motor; wherein, a bearing is mounted between the locking rod and the slideway. The bearing which mounted between the locking rod and the slideway, is to reduce the friction between the locking rod and the slideway, and to prevent the locking rod from moving unsmooth that caused by got stuck from the slideway. When the crank rotates to 90 or 270, and the friction between the locking rod and the slideway is maximum, the locking rod is ensured to move smooth.

A locking mechanism of an inner tub comprises a locking rod and a driving unit for moving the locking rod in an axial direction. A lower end of the locking rod is connected with a link of a crank-link structure, and an idle stroke is arranged between the link and a crank and/or between the link and the locking rod. A locking hole is formed in the bottom of the inner tub. When the locking rod sticks out but not into the locking hole, the locking rod sticks to the bottom of the inner tub, the driving motor drives the crank or the link to move in the idle stroke. When the driving motor drives to move over the highest point, the driving motor further drives the locking rod to move downwards to reset and to re-enter the next working circle.

The present disclosure discloses a front-loading washing machine including a cabinet having a front panel, in which the front panel is provided with an opening; a tub having an access port for loading and unloading clothes, in which the tub is disposed in the cabinet and configured in such a manner that the access port is capable of being moved up and down in the opening; a rotatable drum disposed in the tub; a door unit mounted to the tub and configured to cover the access port; and a driving mechanism configured to drive the tub to rotate, in which the driving mechanism is provided in the cabinet and coupled with the tub. The front-loading washing machine according to embodiments of the present disclosure has advantages of user-friendliness, low clothes abrasion, water saving and the like.

A washing machine that includes an integrated tub/drum that holds water, accommodates laundry, and rotates; a hollow rotary shaft coupled to and passing through one surface of the integrated tub/drum; a water supply pipe and a water drain pipe in the integrated tub/drum and through a passage or opening in the hollow rotary shaft; a nozzle that extends upward from an end of the water supply pipe that is in the integrated tub/drum; and a water drain that extends downward from an end of the water drain pipe that is in the integrated tub/drum.

A washing machine appliance includes a tub positioned within a cabinet, a basket rotatably mounted within the tub and defining a wash chamber for receipt of articles for washing, an agitation element positioned in the wash basket, a motor in mechanical communication with the wash basket and agitation element and being configured for selectively rotating the wash basket and agitation element, a measurement device mounted to the tub for detecting the displacement amount of the tub, and a controller operatively coupled to the motor and measurement device. The controller is configured to control an operation of the motor to rotate the agitation element for a first agitation stroke distance, determine the displacement amount of the tub relative to first and second tub displacement thresholds based on the displacement amount detected by the measurement device, and perform an out-of-balance agitation cycle based on the displacement amount relative to the displacement thresholds.
