Provided are a device and a method for controlling automatic opening and closing of an upper cover of a washing machine. The device includes a controller and a detector. The controller is configured to control a motor to rotate to drive the upper cover to open, close or stop at a current position. The detector is connected to the controller and is configured to collect a signal indicating an obstacle between the upper cover and a tray or on one side of the upper cover facing away from the tray, and send the signal indicating the obstacle to the controller. When the existence of the obstacle between the upper cover and the tray or on the one side of the upper cover facing away from the tray is determined, the controller controls the upper cover to stop at the current position or return to an initial position.

A control method for automatically positioning an inner tub. When the inner tub rotates to a certain position, a positioning pin at the bottom of an outer tub is released to press against the bottom of the inner tub, the inner tub continues to rotate, and when a positioning hole at the bottom of the inner tub is aligned with the positioning pin, the positioning pin stretches into the positioning hole, and thus the inner tub is locked. After the positioning pin is released, the inner tub continues to rotate under the effect of inertia, or the inner tub continues to rotate under the drive of a motor, when the inner tub rotates to the position where the positioning hole is aligned with the positioning pin, the positioning pin stretches into the positioning hole to achieve automatic positioning and locking of the inner tub.

A washing machine contains a wash tub, an impeller and a motor. Clothing is put into the tub and the load is detected. Water is added until the water level is below or equal to load height. To begin washing, the impeller drives the clothing to overturn, resulting in generating three types of water flows: agitating flow, enhancing flow and balancing flow. At first, the agitating flow breaks the balance of the load to disperse clothing, then the enhancing flow overturns clothing for washing. Finally, the balancing flow maintains the circulation path for the load balance overturning. Single sequential control or repeatedly alternating cycle control of the three types of water flows can be adopted for washing. The invention can save water, improve washing efficiency and avoid intertwining of clothing, characterized by full-range, thorough, repeated and efficient washing.
