here, as shown in fig. 12, the spiral coil 40 may be understood as being formed by connecting a plurality of circular rings in series, when the spiral coil 40 is energized, the directions of currents in adjacent rings are the same, and therefore, the directions of magnetic fields formed by adjacent rings are also the same, so that the adjacent rings attract each other, and the whole spiral coil 40 is contracted; as shown in fig. 4, after the power is turned on, the spiral coil 40 is contracted, so that the door seal 30 is correspondingly contracted, the state that the door seal 30 is tightly attached to the box body 1 is changed into a state that a gap is formed, and then the friction force between the door seal 30 and the box body 1 does not exist, so that the door body 2 is convenient to open by a user, the structure is simple, and the use feeling is improved;
when a user closes the door, after the door body 2 is pushed to a closed state, the spiral coil 40 is controlled to be powered off, and then the spiral coil 40 expands to enable the door seal 30 to recover a state of being tightly attached to the refrigerator body 1, so that the refrigerator 100 is sealed, the cold loss is reduced, and the energy consumption is reduced;
meanwhile, in the embodiment of the present invention, energy saving is realized based on the fact that the refrigerator 100 is in the closed state for most of the time, that is, the spiral coil 40 is in the power-off state for most of the time.
In a specific embodiment of the present invention, as shown in fig. 6 to 11, the control device 3 includes a switch electrically connected to the spiral coil 40, the switch includes a push switch 50 disposed on one side of the door 2 close to the box 1, and a protrusion 10 corresponding to the push switch 50 is disposed on one side of the box 1 close to the door 2;
when the convex member 10 presses the push switch 50, the spiral coil 40 is powered off; when the push switch 50 is separated from the projection 10, the spiral coil 40 is energized; here, the push switch 50 may be of various types, such as an electronic type or a mechanical type, and as long as it can be powered off when being pressed, and otherwise powered on, the object of the present invention can be achieved.
Specifically, the switch further comprises a handle 60 arranged in the door body 2 and connected with the push switch 50, and the door body 2 is further provided with a first return spring 70 connected with the handle 60;
when the handle 60 is pulled in a direction away from the case 1, the first return spring 70 is compressed and the push switch 50 is separated from the boss 10;
when the handle 60 is released and the door body 2 is closed, the first return spring 70 is returned to allow the convex member 10 to press the push switch 50; here, when the user opens the door body 2, the user only needs to lightly drive the handle 60 to separate the push switch 50 from the protruding member 10, and then the spiral coil 40 is electrified and contracted to easily open the door body 2, which is simple in structure and convenient in operation.
Preferably, a receiving cavity 61 is formed by inwardly recessing one side of the handle 60 close to the box body 1, the push switch 50 is disposed in the receiving cavity 61, the spiral coil 40 includes two terminals 41, the push switch 50 includes a push piece 51 and contact ends 52 electrically connected to the two terminals 41, respectively, and the push piece 51 is made of a conductive material;

when the pressing piece 51 is separated from the male piece 10, the second return spring 62 is reset to make the pressing piece 51 contact with the two contact ends 52; here, when the door body 2 is pulled away, because the second return spring 62 is reset, the spiral coil 40 is in an energized contraction state, and then it is easier to close the door body 2 and realize a sealing state, because the door seal 30 is in a contraction state, the door body 2 can be easily pushed to a position closed with the refrigerator body 1, at this time, the convex part 10 just presses the pressing part 51, the spiral coil 40 is electrically disconnected and expands, sealing of the refrigerator 100 is completed, the operation of the whole process is simple, and the user experience is improved.
In addition, an iron sheet is arranged on one side of the outer edge of the box body 1 corresponding to the door seal 30. Here, when the door 2 is closed, current is supplied to the spiral coil 40, and the spiral coil 40 generates a magnetic field, and an iron piece is provided at an outer edge of the case 1, so that the iron piece is tightly attracted by the spiral coil 40, thereby further improving an attraction force between the case 1 and the door 2.
As shown in fig. 1 to 3, the outer edge of the protrusion 20 is recessed inward to form a groove 21, and the dock seal 30 is fixedly disposed in the groove 21.
Preferably, the positions of the inner side wall of the box body 1, which are in contact with the door seal 30, are provided with dents, and the positions of the door seal 30, which are in contact with the inner side wall of the box body 1, are provided with dents; of course, if the contact parts of the door seal 30 and the box body 1 are rough, the friction between the door seal 30 and the box body 1 can be greatly improved, and the purpose of the invention can also be achieved.
Optionally, the spiral coil 40 is formed by winding an enameled wire.
In summary, the invention provides a refrigerator 100, wherein the spiral coil 40 is embedded in the door seal 30 surrounding and fixed on the door body 2, and the spiral coil 40 is electrified to contract and is expanded when power is off, so that the sealing degree between the door body 2 and the refrigerator body 1 can be adjusted by simply switching on and off the power, and when the door body 2 is closed, the door body 2 is tightly attached to the refrigerator body 1, thereby reducing the loss of cooling capacity and reducing the energy consumption; when the door body 2 needs to be opened, the door body 2 can be easily opened by controlling the power failure, the operation is simple, and the use feeling of a user is improved; energy saving is achieved based on the refrigerator 100 being in the off state for most of the time, i.e., the solenoid 40 being in the power-off state for most of the time.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make various changes and modifications without departing from the inventive concept, and these changes and modifications are all within the scope of the present invention.
