The invention provides a device and method for removing ice cubes in a refrigerator by means of reciprocal vibration, and relates to field of articles of daily use. The device for removing the ice cubes in the refrigerator by means of reciprocal vibration comprises a left fixed box, wherein a reciprocating driving rod is arranged at the bottom of the left fixed box, the bottom of the reciprocatingdriving rod is bonded to the top of a side hollow fixed cylinder, the bottom of the side hollow fixed cylinder is bonded to the top of a connecting suction cup, and a right mounting box and a grabbing handle are bonded to the right side of the left fixed box. According to the device for removing the ice cubes in the refrigerator by means of reciprocal vibration, after the connecting suction cup is sucked on the ice surface, a driving motor controls a stirring rod to be in contact with protrusion particles, so that the connecting suction cup constantly makes reciprocal vibration after being connected with the ice cubes, and vibration force generated through vibration is utilized for gradually lowering the bonding force between the ice cubes and the inner wall of the refrigerator, which helps to remove large ice cubes. Meanwhile, the ice cubes are not in contact with the refrigerator and do not apply force to the refrigerator either, which avoids the damage to the refrigerator incurredby the traditional mode of ice removal through scraping or heating, and can guarantee the service life of the refrigerator.

The invention discloses a mechanical part paint spraying device. The device comprises a U-shaped base, the upper surface of the U-shaped base is fixedly connected with a plurality of cylinders, and supporting rods are movably connected to the inner walls of the plurality of cylinders in a sleeved mode; the top ends of the plurality of supporting rods are jointly and fixedly connected with a supporting plate, the left side and the right side of the supporting plate are both fixedly connected with first sliding blocks, furthermore, the first sliding blocks are in sliding connection with verticalparts of the U-shaped base, and first sliding grooves matched with the first sliding blocks are correspondingly formed in the opposite sides of the two vertical parts of the U-shaped base; the outerwalls of the cylinders are connected with first springs in a sleeving mode, and the two ends of each first spring are fixedly connected with the upper surface of the U-shaped base and the lower surface of the supporting plate correspondingly; and the upper surface of the supporting plate is fixedly connected with a shell body. The mechanical part paint spraying device is simple to operate, time-saving and labor-saving, convenient and efficient, capable of improving the paint spraying quality of mechanical parts, capable of improving the paint spraying efficiency of the mechanical parts, furthermore capable of reducing the labor intensity of workers and capable of reducing the production cost of enterprises.

The invention discloses a control method of an automatic opening and closing door, the automatic opening and closing door and a household appliance, and belongs to the technical field of smart home. The control method for the automatic opening and closing door comprises the following steps that S1, whether the automatic opening and closing door is subjected to external force or not is detected, and if yes, the step S2 is executed; if not, the step S4 is executed; S2, whether the external force has a trend of changing the current state of the automatic opening and closing door or not is judged, and if yes, the step S3 is executed; if not, the step S4 is executed; S3, the automatic opening and closing door is controlled to change the current state; and S4, the automatic opening and closing door is controlled to keep the current state. The automatic opening and closing door adopts the control method for the automatic opening and closing door. The household appliance is provided with the automatic opening and closing door, and the automatic opening and closing door adopts the control method of the automatic opening and closing door. A user can conveniently intervene in the movement of the automatic opening and closing door in real time, the automatic opening and closing door can make corresponding response according to the action of external force, and the user experience is improved.
