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.

Device and method for controlling automatic opening and closing of upper cover of washing machine

A vibration detection device of washing machine comprises a suspender, a damping spring, a sleeve, a bottom cover and an electromagnetic sensing device. The electromagnetic sensing device comprises an electromagnetic coil and a magnet. The upper end of the suspender is connected with a casing of the washing machine, and the sleeve sleeves the lower part of the suspender in a slidable manner. The damping spring is arranged in the sleeve and at least have two damping springs, and the damping springs have different elastic coefficients and are connected in series. The magnet is connected with the suspender, and the bottom cover is fixedly arranged at the bottom of the sleeve. The electromagnetic coil and the bottom cover are relatively fixed.

Vibration detection device of washing machine

A vibration-damping component of a washing machine comprises a suspender, a spring, a sleeve and an electromagnetic sensing device. The electromagnetic sensing device comprises an electromagnetic coil and a magnet. The electromagnetic coil surrounds the sleeve, the magnet and the spring are arranged in the sleeve and are fixed on the suspender, the sleeve surrounds the suspender in a slidable manner, and the weight of clothing is determined through measuring magnetic flux change of the electromagnetic coil when the sleeve slides on the suspender. In addition, the magnet and the electromagnetic coil make relative displacement, inductance in the electromagnetic coil changes, and water inflow can be detected through detecting the inductance. When dewatering begins, the vibratory magnitude of an outer drum is determined through the inductance change of the electromagnetic coil, and the stability of dewatering operation of the washing machine can be controlled accordingly.

Vibration-damping component of washing machine

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.
