Embodiment 1

[0040] An opening and closing control device for a box door, such as Figure 1-7 As shown, the box door 1 is used to seal the box body 2, the box body 2 is fixed with a door shaft 12, the box door 1 rotates around the door shaft 12, and the opening and closing control device may include:

[0041] A first electromagnet 3, the first electromagnet 3 is fixedly arranged in the box door 1;

[0042] The second electromagnet 4, the second electromagnet 4 is fixedly arranged in the box body 2; the first electromagnet 3 and the second electromagnet 4 repel each other after being magnetized;

[0043] a controller, the controller is used to control whether to magnetize the first electromagnet 3 and the second electromagnet 4;

[0044] A torsion spring 10, one end of the torsion spring 10 is fixed on the lower end of the box door 1, the other end of the torsion spring 10 is fixed on the door shaft 12, the torsion force of the torsion spring 10 is smaller than that of the first The first...

Embodiment 2

[0066] The opening and closing control device of the box door of this embodiment is further improved on the basis of Embodiment 1, as Figure 8-11 As shown, the lower part of the door shaft 12 has a crank 15 extending along the direction perpendicular to the central axis of the door shaft 12, and the crank 15 is provided with a groove 16;

[0067] The control device may also include a stop pin assembly 14, which is fixed to the lower end of the box door 1, and the stop pin assembly 14 is suitable for inserting into the groove 16, so that the Chamber door 1 carries out spacing.

[0068] Further, the crank 15 can be integrated with the door shaft 12, or the crank 15 and the door shaft 12 are two independent parts, the crank 15 is fixedly connected to the door shaft 12, and connected The way can be selected from clamping, riveting, welding or bolting and so on. Those skilled in the art can adaptively select a suitable connection mode between the crank 15 and the door shaft 12 a...

Embodiment 3

[0077] A refrigerator includes a box body and a box door, the box door is hinged on one side of the box body, and the refrigerator also includes the opening and closing control device for the box door described in Embodiment 1 or Embodiment 2. The opening and closing control device of the box door can realize the automatic opening and closing of the box door of the refrigerator.

[0078] In this embodiment, the controller may include a host, and the host may be installed at the lower part of the refrigerator, and the outside of the host may be provided with a moisture-proof and dust-proof protective cover to protect the controller. host of the device.

[0079] The controller can receive and recognize the opening and closing control operation made by the user, and the opening and closing control operation can be selected from: touch operation, button operation, voice operation and the like.

[0080] Wherein, the touch operation is suitable for the case where the controller inc...

Abstract

The invention discloses an opening and closing control device of a refrigerator door and a refrigerator. The refrigerator door is used for sealing a refrigerator body, a door shaft is fixed to the refrigerator body, the refrigerator door rotates around the door shaft, the opening and closing control device comprises a first electromagnet, a second electromagnet, a controller and a torsion spring,the first electromagnet is fixedly mounted in the refrigerator door, the second electromagnet is fixedly mounted in the refrigerator body, the first electromagnet and the second electromagnet are repelled, the controller is used for controlling whether the first electromagnet and the second electromagnet are magnetized or not, one end of the torsion spring is fixed to the lower end of the refrigerator door, the other end of the torsion spring is fixed to the door shaft, and twisting force of the torsion spring is smaller than repulsive force of mutual repulsion after magnetization of the firstelectromagnet and the second electromagnet. According to the technical scheme, box door automatic opening and closing can be achieved, and user experience can be improved.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an opening and closing control device for a box door and a refrigerator. Background technique [0002] In order to make the opening and closing of the box door more convenient to meet the needs of more application occasions and different consumer groups, a control device for realizing the opening and closing of the box door through automatic control has emerged as the times require. Existing automatic control box door (for example: the box door of refrigerator, the box door of incubator, the box door of electric equipment box, the box door of transformer box etc.) the mode of opening and closing usually comprises two kinds of modes. [0003] The first method is to set a retractable ejector rod on the box body, and drive the ejector rod to move through a motor or a penetrating electromagnet, thereby pushing the door open. In this way, when the door is opened...
