Description

Refrigerator door boosting door opening device and method thereof
Technical Field
The invention belongs to the technical field of refrigerator control, and particularly relates to a power-assisted door opening device and a power-assisted door opening method for a refrigerator door.
Background
The refrigerator is a device for preserving food by means of low temperature, in order to keep the refrigerator in a low temperature state continuously, the refrigerator body and a refrigerator door arranged on the refrigerator body are in a closed state under the condition of not storing and taking articles. The common practice is to inlay door seal magnetic stripe around the frame of the box door, and close the box body and the box door by closely sucking the door seal magnetic stripe and the opening surface of the box body made of metal plates, thereby preventing the heat exchange between the inside and the outside of the box body.
When articles are stored and taken, a user only needs to pull the door handle hard, and the door can be opened by overcoming the suction force between the door and the box body by means of the pulling force. After the articles are stored and taken out, the box door is slightly pushed to a closed position, and the box door and the box body are tightly sucked together by means of the attractive force of the door seal magnetic stripe.
Because the attractive force between the door seal magnetic stripe and the box body exists, larger force needs to be overcome when the refrigerator is opened, and larger shaking can be generated at the moment that the door breaks through the attractive force of the magnetic stripe, so that the refrigerator is unfriendly to a user.
There are currently some technologies for opening and closing a door using an auxiliary refrigerator, such as: 1. a motor acceleration and deceleration device is arranged at the door shaft, and the refrigerator door is unscrewed. 2. And an electric push rod or an electromagnetic valve is arranged at the position of the door far away from the door shaft to jack the refrigerator door. 3. By utilizing the lever principle, when an operator presses the unlocking mechanism, the lever mechanism amplifies the pressing force and pushes the refrigerator door open.
The electric auxiliary door opening method of the motor or the electromagnetic valve inevitably generates noise and service life due to a large number of mechanical structures, and the motor and the electromagnetic valve all need larger power, so that the requirements on a power supply are increased and the cost is increased.
Meanwhile, because the auxiliary force application point is limited by the door structure, the auxiliary force application point cannot be always perpendicular to the door opening resistance, namely, a deflection torque can be generated, and the refrigerator door can deflect and deform after long-term use, so that the service life is influenced.
