The server detects the current closing state of a first door body of the refrigerator in real time, wherein the current closing state comprises closing or opening.
Step 602: and determining the moving direction of the magnetic fixing component according to the current closing state of the first door body.
The door body support is arranged on the door body, the drawer is arranged on the other side of the door body support, the magnetic fixing component moves towards the drawer direction to fix the door body support and the drawer when the first door body is closed, and the magnetic fixing component moves towards the side plate direction to separate the door body support and the drawer when the first door body is opened.
The refrigerator comprises a magnetic fixing assembly, the magnetic fixing assembly is used for fixing a door body support with a side plate or a drawer, and the server determines the moving direction of the magnetic fixing assembly according to the current closing state of a first door body, specifically determines whether the magnetic fixing assembly moves towards the side plate or the drawer.
In this application, the server can be when first door body is closed, fixed door body support and drawer, and the user can take out the drawer when opening the second door body like this. The server can also separate the door body support from the drawer when the first door body is opened, and a user opens the second door body and does not bring out the drawer, so that the user can use the drawer at the first door body, and the drawer of the refrigerator is prevented from being used by the user at the first door body side and the user at the second door body side at the same time.
Fig. 7 is a schematic view illustrating the second door body of the refrigerator being opened. As shown in fig. 7, if the first door body of the refrigerator is closed and the magnetic fixing assembly moves toward the drawer, the magnetic fixing assembly fixes the door body bracket and the drawer, that is, the drawer and the second door body are fixed, and if the user pulls open the second door body when the first door body is closed, the drawer can be taken out of the refrigerator body.

step 901: and determining the current direction of the electromagnetic coil assembly according to the current closing state of the first door body.
The current direction of the electromagnetic coil assembly when the first door body is in the opening state is opposite to the current direction of the electromagnetic coil assembly when the first door body is in the closing state.
In the embodiment of the application, when the first door body is opened and closed, current is generated in the electromagnetic coil assembly, but the current directions are opposite. Specifically, when the first door body is in an open state, the server controls the bidirectional change-over switch to be connected with the first line port, so that the current direction of the electromagnetic coil assembly is the first direction; under the condition that the first door body is in a closed state, the server controls the bidirectional change-over switch to be connected with the second line port, so that the current direction of the electromagnetic coil assembly is the second direction, wherein the first direction is opposite to the second direction.
As shown in fig. 2, when the first door body is in a closed state, the bidirectional switch is connected with the first line port 2-4, current passes through the left coil, and the current is in a counterclockwise direction; when the first door body is in an opening state, the two-way change-over switch is connected with the second line port 2-5, current passes through the right coil, and the current is clockwise.
Step 902: the state of the magnetic field between the electromagnetic coil assembly and the magnetic retaining assembly is determined based on the direction of the current flow.
Wherein the magnetic field state comprises the same magnetic field or opposite magnetic fields.
According to the ampere rule principle, the directions of the currents are different, and the directions of the generated magnetic fields are also different. When current passes through the left coil, the direction of a magnetic field generated by the left coil is the same as that of a magnetic field between the magnetic fixing components, and when current passes through the right coil, the direction of the magnetic field generated by the left coil is opposite to that of the magnetic field between the magnetic fixing components. A repulsive force is formed between the electromagnetic coil assembly and the magnetic fixing assembly,
step 903: and controlling the magnetic fixing component to move towards the direction close to or away from the electromagnetic coil component according to the state of the magnetic field.
As shown in fig. 10 and 11, the magnetic fixing component 1-3 comprises magnetic bolts 1-31, jacks 1-32 on the door body bracket, jacks 1-33 on the drawer and jacks 1-34 on the side plates,
fig. 10 is a schematic view of a magnetic latch passing through an insertion hole on a door body bracket and an insertion hole on a drawer. The magnetic field that the left side coil produced is the same with the magnetic field direction between the fixed subassembly of magnetism, forms the repulsion between solenoid subassembly and the fixed subassembly of magnetism, then the fixed subassembly of magnetism moves towards the direction of keeping away from solenoid subassembly, then the jack on the door body support and the jack on the drawer are passed to the magnetism bolt, fixed second door body and drawer.
Fig. 11 is a schematic view of a magnetic latch passing through an insertion hole on a door body bracket and an insertion hole on a side plate. When the magnetic field generated by the left coil is opposite to the magnetic field direction between the magnetic fixing assemblies, attraction force is formed between the electromagnetic coil assemblies and the magnetic fixing assemblies, the magnetic fixing assemblies move towards the direction close to the electromagnetic coil assemblies, and then the magnetic bolts penetrate through the jacks on the door body support and the jacks on the side plates to separate the second door body from the drawer.
Based on the same technical concept, the embodiment of the present application further provides a pull-out module for a drawer of a refrigerator, as shown in fig. 12, the module includes:
