Fig. 1 is a schematic cross-sectional view of a magnetic field preservation storage container 10 in accordance with one embodiment of the present invention. Fig. 2 is a schematic diagram of the magnetic permeable member 110 in the magnetic field preservation container 10 according to one embodiment of the present invention. Fig. 3 is a schematic diagram of the magnetic fields of the magnetic field preservation container 10 with the electrical coil 120 energized, in accordance with one embodiment of the present invention.

As shown in fig. 1 and 2, in the present embodiment, the magnetic field preservation storage container 10 includes a magnetic field generating device 100 and a drawer 200. The magnetic field generating device 100 includes a magnetic conductive member 110 and an electric coil 120, the magnetic conductive member 110 having a first section 111, a second section 112, and a third section 113 connected in sequence. The electrical coil 120 is wound around the second section 112. The drawer 200 is drawably assembled with the magnetic conductive member 110 such that the drawer 200 in the closed position has the first section 111 covering the top of the drawer 200, the second section 112 covering the rear side of the drawer 200, and the third section 113 covering the bottom of the drawer 200.

Referring to fig. 1 and 2, in particular, the magnetic conductive member 110 has a first section 111, a second section 112, and a third section 113 integrally formed. The first section 111, the second section 112 and the third section 113 together form a structure having a cross-sectional shape resembling a "U", the first section 111 and the third section 113 form sides of the "U", and the second section 112 forms an end of the "U". The areas of the first and third sections 111 and 113 are larger than the projected area of the drawer 200 on the horizontal plane.

Further, the drawer 200 is inserted into a space between the first and third sections 111 and 113 from an opening opposite to the second section 112, so that the first section 111 can cover the top of the drawer 200, the second section 112 can cover the rear side of the drawer 200, and the third section 113 can cover the bottom of the drawer 200. Specifically, during use, a user may withdraw the drawer 200 from the magnetic conductive member 110 in the front-to-rear direction of the refrigerator such that the first section 111 no longer covers the top of the drawer 200, and then can place food into the drawer 200. Accordingly, by pushing the drawer 200 back to the closed position, the first section 111 can be made to cover the top of the drawer 200, the second section 112 can cover the rear side of the drawer 200, and the third section 113 can cover the bottom of the drawer 200.

As shown in connection with fig. 3, when the electric coil 120 is energized with an electric current, the electric coil 120 is capable of generating a magnetic field. As indicated by the arrow, the magnetic field is directed from the first segment 111 to the third segment 113 under the guidance of the magnetically permeable member 110. In other words, since the electric coil 120 is wound around the second segment 112, when the electric coil 120 is supplied with current, it is equivalent to making the first segment 111 and the third segment 113N-pole and S-pole, respectively (as shown in N, S in fig. 3). Meanwhile, since the first and third sections 111 and 113 cover the top and bottom of the drawer 200, respectively, the magnetic field directed from the first section 111 to the third section 113 passes through the inside of the drawer 200 and covers the entire space of the drawer.

Therefore, in the solution of the present embodiment, on the one hand, a relatively uniform magnetic field can be formed in the drawer 200. And, the magnetic conduction piece 110 is a three-section integrated body, so the structure is simple, and the installation is convenient. And the magnetic conduction piece 110 of three-section type cooperates with electric coil 120, only need an electric coil 120 to form comparatively even magnetic field, have reduced the quantity of the electric coil 120, simplify the line structure. On the other hand, the first section 111 of the magnetic conduction piece 110 covers the top of the drawer, so that the effect of preventing cold air from directly blowing food materials is achieved, temperature fluctuation of the food materials is reduced, and fresh meat state of the food materials is maintained.

In addition, by locating the second section 112 at the rear side of the drawer 200, the second section 112 is hidden at the rear side of the drawer 200, so that the portion of the magnetic conductive member 110 exposed in the field of view of the user is reduced, and the overall aesthetic appearance of the magnetic field preservation storage container 10 is improved.

It should be noted that, in other embodiments of the present application, the second section 112 may also be located on the left side or the right side of the drawer 200. That is, the drawer 200 in the closed position may have the second section 112 cover the left or right or rear side of the drawer 200.

In addition, by winding the electric coil 120 around the second section 112, the magnetic field strength at the first section 111 and the third section 113 is made the same, thereby further improving the uniformity of the magnetic field within the drawer 200.

As shown in fig. 1 and 2, further, the side of the first section 111 facing the drawer 200 is provided with a boss 114 facing the drawer 200, and the side of the third section 113 facing the drawer 200 is also provided with a boss 114 facing the drawer 200.

Specifically, the projection of the boss 114 falls within the projection of the drawer 200 on the same horizontal plane, in other words, the projected area of the boss 114 is equal to or slightly smaller than the projection of the drawer 200.

It will be appreciated that by providing the bosses 114 on the first and third sections 111, 113, the bosses 114 facilitate concentrating the magnetic field into the drawer 200, thereby increasing the effective magnetic field strength within the drawer 200.

It should be noted that one of the first section 111 and the third section 113 may be provided with a convex portion.

Fig. 4 is a schematic cross-sectional view of a magnetic field preservation storage container 10 in accordance with another embodiment of the present invention.

Referring to fig. 2 and 4, in the present embodiment, the magnetic field preservation container 10 includes an induction coil 300. The induction coil 300 is wound around the boss 114. Specifically, the side of the first and third sections 111, 113 facing the drawer 200 is provided with a boss 114 facing the drawer 200. The bosses 114 of the first section 111 and the bosses 114 of the third section 113 are each wound with an induction coil 300.

Specifically, in the case where the electric coil 120 is energized, the generated magnetic field passes through the induction coil 300. Thus, when the magnetic field generated by the electric coil 120 changes (e.g., when it is desired to increase the magnetic field strength or decrease the magnetic field strength, or in the case where the electric coil 120 is energized with an alternating current), an induced current can be generated in the induction coil 300.

Further, the induction coil 300 generating the induction current can generate a magnetic field, and since the magnetic field generated by the induction coil 300 can block the change of the magnetic field of the electric coil 120, the rate of the change of the magnetic field can be reduced, and the magnetic field in the drawer 200 is prevented from generating large fluctuation, thereby affecting the storage effect.

It should be noted that the induction coil 300 may be provided only in one boss 114.

Fig. 5 is a schematic cross-sectional view of a magnetic field preservation storage container 10 in accordance with yet another embodiment of the present invention. Fig. 6 is a schematic diagram of the magnetic fields of the magnetic field preserving container 10 with the electrical coil 120 energized in accordance with yet another embodiment of the present invention.

As shown in fig. 5 and 6, in the present embodiment, the electric coil 120 is wound around the first section 111, and the winding position of the electric coil 120 is close to the second section 112. Specifically, the electrical coil 120 is wound in a position that conforms to the second section 112.

Likewise, when the electric coil 120 is energized with an electric current, the electric coil 120 is capable of generating a magnetic field. As indicated by the arrow in fig. 6, the magnetic field is directed from the first segment 111 to the third segment 113 under the guidance of the magnetically permeable member 110. In other words, when the electric current is applied to the electric coil 120, the first segment 111 and the third segment 113 are made to be N-pole and S-pole, respectively (as shown by N, S in fig. 6). Meanwhile, since the first and third sections 111 and 113 cover the top and bottom of the drawer 200, respectively, the magnetic field directed from the first section 111 to the third section 113 passes through the inside of the drawer 200 and covers the entire space of the drawer.

It should be noted that the electric coil 120 may also be wound around the third section 113. That is, the electric coil 120 may be wound on one of the first, second and third sections 111, 112 and 113.

Further, as shown in fig. 5, the thickness of the portion of the first segment 111 wound by the electrical coil 120 is less than the thickness of the remaining portion. In one aspect, a groove for placing the electrical coil 120 is formed between the first section 111 and the second section 112, thereby facilitating winding of the electrical coil 120. On the other hand, the magnetic field is easily deflected rearward from the portion of the first section 111 where the electrical coil 120 is not wound, to improve the uniformity of the magnetic field within the drawer 200.

The same configuration may be made in the case where the electric coil 120 is wound around the third section 113.

In addition, in the case where the electric coil 120 is wound around the first section 111 (or the third section 113), the third section 113 (or the first section 111) may be provided with a protrusion and wound around the induction coil.

With continued reference to fig. 5 and 6, the magnetic field preservation storage container 10 includes a magnetic sheet 400, the magnetic sheet 400 being disposed on a bottom surface of an interior of the drawer 200, an area of the magnetic sheet 400 being adapted to an area of the bottom surface of the interior of the drawer 200. The magnetic field of the magnetic sheet 400 is in the same direction as the magnetic field generated by the magnetic field generating device 100.

Therefore, the magnetic sheet 400 can function to increase the overall magnetic field strength, and can compensate for a relatively small magnetic field in the rear.

When the magnetic sheet 400 is set to have the electric coil 120 as a direct current.

Fig. 7 is a schematic cross-sectional view of a refrigerator 1 according to an embodiment of the present invention.

As shown in fig. 7, in one embodiment, the refrigerator 1 includes a magnetic field fresh storage container 10, a case 20, and a door 30. Wherein the case 20 is formed with a storage compartment 210. The magnetic field preservation storage container 10 is disposed in the storage compartment 210. The magnetic field preservation storage container 10 is the magnetic field preservation storage container 10 according to any one of the above embodiments.

Further, the door 30 is pivotally connected to the case 20 for closing the storage compartment 210. The box 20 is provided with a refrigerating cavity 220, and an evaporator and a fan are arranged in the refrigerating cavity 220. The activated blower blows the cool air in the cooling chamber into the storage compartment 210.

Referring to fig. 1 and 7, the rear sidewall of the storage compartment 210 is provided with an air inlet 230, and the air inlet 230 is located higher than the first section 111. Cold air is blown into the storage compartment 210 from the air inlet 230.

In the solution of the present embodiment, the air inlet 230 is disposed higher than the first section 111, so that the air flow entering the storage compartment 210 can flow more smoothly. And flows forward along the first section 111, which in turn creates an air flow around the magnetic field fresh storage vessel 10.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
