It should be noted that the wireless charging receiving module 41 is directly opposite to the wireless charging transmitting module 50. When the drawer 20 is pushed into the compartment body 10, the wireless charging receiving module 41 is matched with the wireless charging transmitting module 50, and the wireless charging receiving module 41 can receive an electromagnetic signal sent by the wireless charging transmitting module 50 to generate a current, so that the magnetic part 42 generates a magnetic field, and the magnetic field and the electromagnetic preservation module 30 generate attraction force to drive the drawer 20 to move and tightly close in the compartment body 10, thereby preventing cold air leakage, maintaining the balance of temperature and humidity in the drawer 20, and further improving the preservation effect of the refrigerator.

In the embodiment of the present invention, the magnetic member 42 is an electromagnet, also called a helmholtz coil, and the polarity and the magnetic field strength of the magnetic member 42 adjacent to the electromagnetic refreshing module 30 can be adjusted by controlling the direction and magnitude of the current passing through the coil.

It is understood that the magnetic member 42 may be disposed opposite to the first electromagnetic plate 31 to generate an attraction force with the first electromagnetic plate 31, and may be disposed opposite to the second electromagnetic plate 32 to generate an attraction force with the second electromagnetic plate 32.

Illustratively, the first current is controlled to flow through the first electromagnetic plate 31, and the second current is controlled to flow through the magnetic member 42, so that the polarities of the adjacent sides of the magnetic member 42 and the first electromagnetic plate 31 are different, such as the polarity of the adjacent side of the first electromagnetic plate 31 and the magnetic member 42 is S-pole, and the polarity of the adjacent side of the magnetic member 42 and the first electromagnetic plate 31 is N-pole. It should be noted that the polarity of the side of the magnetic member 42 adjacent to the first electromagnetic plate 31 is not limited thereto, such as the polarity of the side of the first electromagnetic plate 31 adjacent to the magnetic member 42 is N-pole, and the polarity of the side of the magnetic member 42 adjacent to the first electromagnetic plate 31 is S-pole. So that an attractive force is generated between the magnetic member 42 and the first electromagnetic plate 31 to drive the drawer 20 to move into the chamber body 10 for sealing.

For example, the first magnetic member 421 and the second magnetic member 422 are connected to the wireless charging receiving module 41 through the wire 44.

The first magnetic member 421 and the second magnetic member 422 are electromagnets. It should be noted that the first magnetic member 421 can be disposed opposite to the first electromagnetic plate 31, and the second magnetic member 422 can be disposed opposite to the second electromagnetic plate 32. By controlling the direction of the current passing through the first magnetic member 421 and the first electromagnetic plate 31, the polarity of the adjacent side of the first magnetic member 421 and the first electromagnetic plate 31 can be adjusted to be opposite, so that the first magnetic member 421 and the first electromagnetic plate 31 generate a first attractive force; by controlling the direction of the current passing through the second magnetic member 422 and the second magnet plate 32, the polarity of the side of the second magnetic member 422 adjacent to the second magnet plate 32 can be adjusted to be opposite, so that the second magnetic member 422 and the second magnet plate 32 generate a second attractive force. The first attraction force and the second attraction force jointly drive the drawer 20 to move to the compartment main body 10 for sealing, so that the drawer 20 is tightly closed in the accommodating cavity 11, cold air leakage is avoided, the temperature and humidity balance in the drawer 20 is maintained, and the preservation effect of the refrigerator is further improved.

It should be noted that, when the second electromagnetic plate 32 is a permanent magnet, by controlling the direction of the current passing through the second magnetic member 422, the polarities of the adjacent sides of the second magnetic member 422 and the second electromagnetic plate 32 can be adjusted to be opposite, so that the second magnetic member 422 and the second electromagnetic plate 32 generate the second attractive force.

In the embodiment of the present application, when the distance between the wireless charging receiving module 41 and the wireless charging transmitting module 50 is greater than the preset distance, for example, the preset distance is set to 1 cm, the wireless charging receiving module 41 terminates receiving the electromagnetic signal sent by the wireless charging transmitting module 50, and the wireless charging receiving module 41 cannot generate current, so that the current and the magnetic field of the magnetic member 42 disappear, and the attraction between the magnetic member 42 and the electromagnetic refreshing module 30 also disappears.

For example, when the drawer 20 is pulled out of the compartment body 10, or the user forgets to close the drawer 20, which results in that the distance between the wireless charging receiving module 41 and the wireless charging transmitting module 50 exceeds the preset distance, the wireless charging receiving module 41 stops receiving the electromagnetic signal sent by the wireless charging transmitting module 50, so that the current and magnetism of the magnetic member 42 disappear, and the attraction between the magnetic member 42 and the electromagnetic preservation module 30 also disappears.

The indicator lamp 43 may be provided on the drawer panel 20 together with the magnetic member 42. The indicator lamp 43 indicates the sealing state of the drawer 20 and the compartment body 10. For example, when the drawer 20 is pushed into the compartment body 10 and the distance between the wireless charging receiving module 41 and the wireless transmitting module is within the preset distance range, the wireless charging receiving module 41 may receive the electromagnetic signal transmitted by the wireless charging transmitting module 50 and generate a current, which is equivalent to that the electromagnetic sealing module 40 is powered on, the indicator lamp 43 is turned on in the power-on state, and the magnetic member 42 and the electromagnetic preservation module 30 may generate an attractive force, so that the drawer 20 is sealed in the compartment body 10. It will be appreciated that the indicator light 43 is illuminated to indicate that the drawer 20 is sealed properly.

Illustratively, when the drawer 20 is drawn out from the compartment body 10, or the user forgets to close the drawer 20, and the distance between the wireless charging receiving module 41 and the wireless transmitting module exceeds the preset distance, the wireless charging receiving module 41 terminates receiving the electromagnetic signal sent by the wireless charging transmitting module 50, which is equivalent to that the power supply of the electromagnetic sealing module 40 is interrupted, and the indicator lamp 43 is turned off, indicating that the drawer 20 is not sealed well.
