Description
Technical Field
The invention belongs to the technical field of household appliances, and particularly relates to a control method for automatically opening a door of a refrigerator.
Background
Most of the existing refrigerators are opened manually, so that people are inconvenient to hold articles to open the refrigerator door by hands, and the problems can be well solved by the automatic door opening refrigerator.
The automatic door-opening refrigerator disclosed at present realizes automatic door opening through a push rod mechanism. The principle of the method is that the suction force of the door seal is overcome through the ejector rod mechanism, and then the door body is completely ejected. Some large-volume refrigerators have large door seal suction force, and in order to overcome the door seal suction force, the ejector rod mechanism generally needs to lift the ejection force of the ejector rod mechanism to meet the door opening requirement. Although the door body can be opened, the new problem is brought about: in the jacking process, the door body has high moving speed and high noise, and is easy to hurt users, especially children or old people. Therefore, there is a need for an automatic door opening control method for a refrigerator, which is simple in structure and safe.

In order to solve the technical problems, the invention is realized by the following technical scheme:
the invention relates to a control method for automatically opening a door of a refrigerator, wherein the refrigerator comprises an electromagnetic coil, a door seal with the built-in electromagnetic coil, a mandril mechanism and a main control panel of the refrigerator; the electromagnetic coil and the ejector rod mechanism are electrically connected with a main control board of the refrigerator; the control method comprises the following steps:
step one, after the refrigerator is powered on, a refrigerator main control panel monitors the closing state or the opening state of each door body in the refrigerator;
step two, when the refrigerator main control board receives a door opening signal, if the refrigerator main control board monitors that a door body in the refrigerator is in a closed state, entering step three; otherwise, namely the refrigerator main control board monitors that the door body in the refrigerator is in an opening state, the ejector rod mechanism does not act;
step three, the refrigerator main control board performs power-off operation on the electromagnetic coil, and at the moment, the suction force of the door seal disappears;
and fourthly, the refrigerator main control board starts the push rod mechanism, and the door body of the refrigerator is automatically pushed away by the push rod mechanism.
Furthermore, electromagnetic coils are uniformly arranged inside the door seal; the electromagnetic coil is uniformly distributed, so that the attraction force of the door seal strip when the electromagnetic coil is electrified is relatively more uniform.
Furthermore, the refrigerator main control board controls the on-off of the electromagnetic coil, and then controls the generation and disappearance of the suction force of the door seal; when the door body needs to be automatically opened, the suction force of the door seal strip disappears, so that the door body is greatly convenient to operate and control by the ejector rod mechanism, the opening and closing control of the door body by the ejector rod mechanism is more stable, the door body is opened at a relatively slow speed, the safety is high, and the operation is stable.
Further, the refrigerator main control board controls the starting/closing of the ejector rod mechanism.
The invention has the following beneficial effects:
1. the control method for automatically opening the door of the refrigerator can realize automatic door opening on the premise of ensuring the safety of a user as much as possible when the door is opened; the method is characterized in that before the ejector rod mechanism is started, the suction force of the door seal disappears, namely the ejector rod mechanism only needs to use relatively small force to push the door body away slightly, the opening speed of the door body is relatively slow, the noise caused by the opening speed is low, and the user can be prevented from being injured when the door is opened.
2. Compared with the existing automatic door opening control method, the automatic door opening control method has the advantages that the problem that the door body moving speed is too high due to the fact that the door body is endowed with high acceleration at the moment when the ejector rod mechanism overcomes the suction force of the door seal and then reaches the force required by door opening can be solved; the door body moving speed is more controllable and properly adjusted, the safety of automatic door opening is extremely high, and the use safety and the excellent experience of a user are guaranteed.
Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
