摘要： A washing machine inner barrel and a washing machine are disclosed, the inner barrel comprises a barrel bottom and a barrel body connected thereto. The barrel bottom comprises a barrel bottom body and a barrel bottom protective cover. The barrel bottom protective cover is hermetically mounted on the bottom of the barrel bottom body so that the entire outer surface of the barrel bottom becomes a smooth surface. The outer surface of the barrel bottom protective cover of the washing machine inner barrel is a smooth flat surface, which is more conductive to the cleaning effect of the particles on the inner barrel bottom. The barrel bottom protective cover is hermetically connected with the bottom of the barrel bottom body so that a reinforcing rib structure is in an enclosed space to prevent washing water from entering the reinforcing rib structure.

摘要： 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.

摘要： Disclosed is a washing machine failure detection and processing method, comprising the following steps: a PC pointer detection step: respectively detecting various running processes of a washing machine; respectively detecting whether a current value of a logical register is the same as an assigned value after the running of various subprograms is ended, and if the current value is different from the assigned value, judging that a PC pointer fails, and keeping a record of a current failure occurring in which running process of the washing machine according to the assigned value; and when it is judged that the PC pointer fails, waiting for a time t1, and continuing to detect whether the current value of the logical register is the same as the assigned value, and if so, continuing to execute the subprogram, otherwise executing system resetting. In the washing machine failure detection and processing method in the present invention, an internal running error is prevented from occurring in an algorithm of a washing machine, a failure is detected by a system before being found by a user, and a corresponding security control measure is adopted, thereby guaranteeing the secure running of the washing machine.

摘要： 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.
