Description

Food storage device

Technical Field

The present invention relates to a food storage device, and more particularly, to a food storage device having a reduced wall thickness and an improved sealing effect.

Background

The food storage device is a device that stores food at a predetermined temperature. Such as refrigerators and freezers of the prior art.

Sealing is essential to ensure the temperature within the food storage device. The sealing gasket of the existing refrigerator is arranged on the rear surface of a door frame, and is tightly attached to the front end of a shell in a state of closing a refrigerator door.

The provision of such a gasket requires a predetermined wall thickness of the housing in order to achieve a satisfactory sealing effect.

Referring to fig. 14, fig. 14 illustrates a related art refrigerator in a state where a door 200 is opened. As shown in fig. 14, a gasket 200a is provided on the rear surface of the door 200, and a contact surface 100a that comes into contact with the gasket 200a is provided on the front end of the housing 100.

Here, the greater the width of the gasket 200a, the better the sealing effect. However, the increase in the width of the gasket 200a requires an increase in the width of the contact surface 100a, that is, the thickness of the housing 100, which increases the thickness of the housing 100.

Currently, the volume of food storage devices is fixed. In order to satisfy the limited volume and increase the internal volume, the wall thickness of the food storage device needs to be thinned. If the wall thickness is simply thinned, the contact area of the gasket 200a and the close contact surface 200a of the housing is reduced, thereby affecting the sealing effect.

Detailed Description

The food storage device 1 of the present invention may be applied to a drawer type refrigerator that is drawn out of and pushed into a casing, and may also be applied to a refrigerator whose door is rotated by a hinge.

First, a case where the food storage device 1 is a drawer type refrigerator will be described.

Referring to fig. 1 and 2, the food storage device 1 of the present invention may include: a housing 10 having a receiving space 10' formed therein, at least one side of which is open; the drawer type storage box 20 can be inserted into the space through the open surface of the housing 10. In a state where the drawer type storage box 20 is inserted into the housing 10, the open surface of the housing 10 is closed.

The drawer type storage box 20 may be pushed into the housing 10 and pulled out from the housing 10 in the front-rear direction.

It should be noted that the front, rear, upper, lower, left, and right directions described herein refer to directions or orientations. The drawer type storage box 20 is drawn out from the casing 10 in a forward direction, is pushed into the casing 10 in a rearward direction, and has an open upper portion facing upward and a lower portion facing downward. Further, the front-rear direction refers to a direction in which the drawer type storage box 20 is pulled out and pushed in.

Referring to fig. 2 to 4, the drawer type storage box 20 may include: a door panel 21 that opens and closes the open surface of the housing 10; the receiving part 22 is formed with a space for storing food therein, coupled to the rear surface 21a of the door plate 21, and inserted into the receiving space 10' of the housing 10. Here, the accommodating portion 22 protrudes rearward from the door panel 21, and therefore, the accommodating portion 22 may be referred to as a protruding portion 22. Hereinafter, in the case of describing the drawer type refrigerator, the description will be continued using the storage portion 22 for convenience of description.

The door panel 21 and the accommodating portion 22 may be formed integrally or may be connected together by a fastening member such as an adhesive or a bolt.

The accommodating portion 22 may be formed in a box shape whose upper portion is opened.

The rear surface 21a of the door panel 21 may be combined with the front plate 22a of the receiving portion 22. The front plate 22a is a part of a space for storing food, which forms the receiving part 22. Specifically, the accommodating part 22 encloses a space for storing food by the front plate 22a, the rear plate 22b, the left plate 22c, the right plate 22d, and the bottom plate 22 e.

Although not shown, the bottom plate 22e of the accommodating part 22 may be provided with wheels so that the accommodating part 22 slides within the inner space of the housing 10. Or the left and right plates 22c and 22d of the receiving portion 22 are provided with slide rails, and guides corresponding to the slide rails are formed at the inner sides of the left and right walls of the housing 10 so that the receiving portion 22 slides in the inner space of the housing 10.

The rear surface 21a of the door panel 21 may have a larger area than the front plate 22a of the receiving portion 22.

Referring to fig. 7, the case 10 may include a space surrounded by upper, lower, left, right, and rear walls. Here, the housing 10 is open without a front wall for inserting and pulling out the drawer type storage box 20.

A protruding plate 12 is formed at the front end of at least one of the upper, lower, left, and right walls of the case 10. Hereinafter, for convenience of description, the upper wall, the lower wall, the left wall, and the right wall are collectively referred to as the wall 11. Here, the front end refers to an end portion on the side of the open face of the housing 10, that is, an end portion away from the rear wall.

The projecting plate 12 may be formed integrally with the wall portion 11, or may be bonded by an adhesive or the like after being separately manufactured.

The projecting plate 12 may project from the entire front end of the wall 11 in a direction in which the drawer type storage box 20 is drawn out (i.e., forward).

The projection plate 12 may be provided at the front end of the wall portion 11 around the open opening of the housing 10.

The projecting plate 12 may be a plate projecting from the front end of the wall portion 11.

The convex plate 12 has a convex inner surface 12a and a convex outer surface 12b opposite the convex inner surface 12 a. The convex inner surface 12a faces the accommodating portion 22, and the convex outer surface 12b faces the outside of the housing 10.

The wall 11 may have an inner wall surface 11a and an outer wall surface 11 b. The inner wall surface 11a of the wall 11 may be adjacent to or in contact with the receiving portion 22 of the drawer type storage box 20, and the outer wall surface 11b of the wall 11 may form an outer surface of the housing 10.

The distance between the inner wall surface 11a and the outer wall surface 11b of the wall portion 11 is larger than the distance between the convex inner surface 12a and the convex outer surface 12b of the convex plate 12. That is, the thickness of the wall portion 11 may be thicker than that of the projection plate 12.

The convex outer surface 12b of the convex plate 12 may be in the same plane as the outer wall surface 11b of the wall portion 11, i.e. coplanar.

The convex inner surface 12a of the convex plate 12 and the inner wall surface 11a of the wall portion 11 have a height difference therebetween. For example, in the case of the lower wall, the inner wall surface of the lower wall is closer to the upper side than the convex inner surface of the convex plate that protrudes from the lower wall; in the case of the upper wall, the inner wall surface of the upper wall is located closer to the lower side than the convex inner surface of the convex plate that protrudes from the upper wall; in the case of the left wall, the inner wall surface of the left wall is closer to the right than the convex inner surface of the convex plate that protrudes from the left wall; in the case of the right wall, the inner wall surface of the right wall is closer to the left than the convex inner surface of the convex plate that protrudes from the right wall.

When the front end of the wall portion 11 is viewed from the front of the housing 10, the inner wall surface 11a of the wall portion 11 is located further toward the internal space of the housing 10 than the inner convex surface 12a of the convex plate 12, in other words, the inner wall surface 11a of the wall portion 11 is located closer to the accommodating portion 22 of the drawer type storage box 20 than the inner convex surface 12a of the convex plate 12 in a state where the drawer type storage box 20 closes the housing 10.

The front end of the wall portion 11 is provided with a pressing surface 11c, and the pressing surface 11c is connected to a convex inner surface 12a of the convex plate 12.

The pressing surface 11c may be provided between the inner wall surface 11a and the convex inner surface 12a, and connects the inner wall surface 11a and the convex inner surface 12 a.

The pressing surface 11c may be a part of the front end of the wall portion 11.

The surface of the front end of the wall portion 11 may be provided with a pressing surface 11c and a projecting plate 12. That is, of the front end surface of the wall portion 11, a portion close to the outer wall surface 11b is provided with the bulging plate 12, and a portion close to the inner wall surface 11a is provided with the pressing surface 11 c.

The pressing surface 11c may be perpendicular to the convex inner surface 12a of the convex plate 12.

The pressing surface 11c may be perpendicular to the inner wall surface 11 a.

That is, the inner wall surface 11a and the convex inner surface 12a may be parallel to each other, but not on one plane, and the distance between the inner wall surface 11a and the convex inner surface 12a may be the width of the pressing surface 11 c. The pressing surface 11c may be disposed between the inner wall surface 11a and the convex inner surface 12a, and connected to the inner wall surface 11a and the convex inner surface 12a, respectively.

Referring to fig. 3 to 6, the drawer type storage box 20 may further include a sealing member 23 disposed at the rear of the door panel 21. The sealing member 23 is elastically deformable, and for example, the sealing member 23 may be formed of an elastically deformable material such as rubber for sealing the storage space.

The sealing member 23 may have a hollow sealing hollow 231.

The receiving portion 22 may pass through the sealing hollow 231. Specifically, the receiving portion 22 may penetrate the sealing hollow portion 231 to be combined with the rear surface 21a of the door panel 21.

In a state where the drawer type storage box 20 closes the housing 10, the sealing member 23 is in close contact with the pressing surface 11c and the convex inner surface 12a, thereby achieving a sealing effect.

In a state where the drawer type storage box 20 closes the housing 10, one surface of the sealing member 23 is pressed by the pressing surface 11c, and a surface opposite to the one surface is pressed by the rear surface 21a of the door panel 21, and therefore, the sealing member 23 can be elastically deformed, specifically, protruded outward, outward (in a direction opposite to the accommodating portion 22) by the pressing of the pressing surface 11c and the rear surface 21a of the door panel 21. The sealing member 23 is closely attached to the convex inner surface 12a of the convex plate 12 after protruding outward.

Therefore, in a state where the drawer type storage box 20 closes the housing 10, the sealing member 23 is in close contact with the pressing surface 11c and the convex inner surface 12a of the convex plate 12. Thereby, the storage space can be sealed by the sealing member 23.

The other surface of the sealing member 23 can also be in close contact with the housing portion 22, and therefore, when the sealing member 23 is pressed by the pressing surface 11c, three surfaces of the sealing member 23 are pressed, and only the surface facing the projecting plate 12 is not pressed, and therefore the sealing member 23 projects only toward the projecting inner surface 12a of the projecting plate 12 and is in close contact with the projecting inner surface 12 a.

For convenience of explanation, three faces of the sealing member 23 to be pressed are named as follows: of the surfaces of the sealing member 23, a surface that is in close contact with the rear surface 21a of the door panel 21 is referred to as a first close contact surface 23a, a surface that is in close contact with the outer surface of the accommodating portion 22 is referred to as a second close contact surface 23b, a surface that is in close contact with the pressing surface 11c is referred to as a third close contact surface 23c, and a surface that protrudes toward the inner surface 12a of the projecting plate 12 is referred to as a fourth close contact surface 23 d. Here, the second close contact surface 23b forms the seal hollow portion 231.

Here, the first and second close-up faces 23a and 23b of the sealing member 23 may be adhered to the rear surface 21a of the door panel 21 and the outer side face of the accommodating portion 22, respectively, by an adhesive.

In the present embodiment, the sealing member 23 may be provided at the rear surface 21a of the door panel 21 around the accommodating portion 22. Here, the sealing member 23 may be formed in a square plate shape having a hollow interior (sealing hollow portion 231). The first contact surface 23a of the sealing member 23 is in contact with the rear surface 21a of the door panel 21, and the second contact surface 23b, which is a hollow inner surface, is in contact with the accommodating portion 22. In the present embodiment, the second close-contact surface 23b of the seal member 23 is in close contact with the outer end of the front plate 22a of the accommodating portion 22 that is joined to the rear surface 21a of the door panel 21.

The thickness of the sealing member 23 may be the same as or thinner than the thickness of the front plate 22a of the receiving portion 22.

The lengths of the second to fourth close faces 23b to 23d of the seal member 23 may be smaller than the width of the pressing face 11 c. Here, the width of the pressing surface 11c may be a perpendicular distance between the inner wall surface 11a and the convex inner surface 12 a.

In the process of closing the housing 10 by the drawer type storage box 20, the accommodating portion 22 is inserted into the receiving space 10' of the housing 10, and the sealing member 23 is closely attached to the rear surface 21a of the door panel 21, so that the third closely attaching surface 23c of the sealing member 23 is first closely attached to the pressing surface 11c and pressed by the pressing surface 11c when the door panel 21 is about to close the housing 10. At this time, the sealing member 23 is pressed by the pressing face 11c and the rear surface 21a of the door panel 21, and expands toward the outside and the inside. Here, the surface expanding toward the inside (i.e., toward the accommodating portion 22) is the second contact surface 23b, and the surface expanding toward the outside (i.e., toward the convex inner surface 12a) is the fourth contact surface 23 d. Since the second close contact surface 23b is abutted by the front plate portion 22a of the accommodating portion 22 to prevent the second close contact surface 23b from expanding, only the fourth close contact surface 23d of the sealing member 23 expands and presses and abuts against the convex inner surface 12a of the convex plate 12. Thereby, the sealing member 23 can isolate the outside from the inner space of the housing 10, achieving a sealing effect. The third contact surface 23c and the pressing surface 11c are also in a contact state, so that the sealing effect is further achieved.

The first fastening face 23a may be perpendicular to the second fastening face 23b and parallel to the third fastening face 23 c. The fourth fastening surface 23d may be parallel to the second fastening surface 23 b. Therefore, the cross section of the sealing member 23 may be rectangular.

The invention can reduce the wall thickness of the wall part 11 and achieve good sealing effect at the same time through the structure.

It is clearly understood by those skilled in the art that the projecting plate 12 may be provided only at the lower wall and the sealing member 23 may be provided in a portion corresponding to the lower wall in the rear surface 21a of the door panel 21, as needed, for example, if those skilled in the art need to reduce the wall thickness of only the lower wall.

The sealing member 23 is provided to wrap the front plate 22a of the accommodating portion 22. The sealing member 23 extends outward from the receiving portion 22 by a predetermined distance when viewed from the rear of the drawer type storage box 20. When the drawer type storage box 20 closes the housing 10, the third contact surface 23c of the sealing member 23 extending from the accommodating portion 22 is pressed by the pressing surface 11 c.

However, in practice, the width of the pressing surface 11c (i.e., the length in the thickness direction of the wall portion 11) is not so wide in consideration of the thickness of the wall portion 11, and therefore, the portion where the pressing surface 11c presses the sealing member 23 is limited. Therefore, the extending length of the sealing member 23 (i.e., the length extending outward from the housing portion 22) is also limited. For example, in the case where the width of the pressing surface 11c is 1cm, the sealing member 23 should be 1cm or less. If 1cm or more, a part of the sealing member 23 cannot be pressed by the pressing surface 11 c. Thereby, the sealing member 23 may not be able to be completely projected toward the projecting plate 12, and a part may be projected toward the other direction, eventually causing a problem of lowering the sealing effect. Therefore, it is necessary to increase the extension length of the sealing member 23 and to project the sealing member 23 in the direction of the projecting plate 12 as much as possible while ensuring the thickness of the wall portion 11.

Referring to fig. 8 to 13, in order to solve the technical problem, the drawer type storage box 20 of the present invention may include: a door panel 21 for opening and closing the open surface of the housing 10; a receiving part 22 having an open upper portion for receiving food; and a connecting portion 24 connecting the door panel 21 and the accommodating portion 22.

The connecting portion 24 may be formed integrally with the accommodating portion 22 or may be formed integrally with the door panel 21. The connecting portion 24 may be fixedly coupled with the accommodating portion 22 and/or the door panel 21 by an adhesive.

The connecting portion 24 may be formed in a cylindrical shape or a rectangular parallelepiped shape.

The connecting portion 24 has one end connected to the rear surface 21a of the door panel 21 and the other end connected to the front plate 22a of the accommodating portion 22. Preferably, the connecting portion 24 connects the center of the rear surface 21a of the door panel 21 and the center of the front plate portion 22a of the accommodating portion 22.

The sectional area of the connecting portion 24 is smaller than the surface area of the rear surface 21a of the door panel 21 and smaller than the surface area of the front plate 22a of the accommodating portion 22. For example, the connecting portion 24 may be formed in a cylindrical shape having the same cross-sectional area, and thus the area of the surface of the connecting portion 24 connected to the rear surface 21a of the door panel 21 is the same as the area of the surface connected to the front plate 22a of the accommodating portion 22. Hereinafter, for convenience of description, a surface of the connection portion 24 connected to the rear surface 21a of the door plate 21 is referred to as a first connection surface 24a, and a surface connected to the front plate 22a of the receiving portion 22 is referred to as a second connection surface 24 b.

Therefore, the first connection surface 24a and the second connection surface 24b have the same surface area, and are smaller than the surface area of the rear surface 21a of the door panel 21 and smaller than the surface area of the front plate 22a of the receiving portion 22. Further, the surface area of the front plate 22a is smaller than the surface area of the rear surface 21a of the door panel 21.

Preferably, the first connection surface 24a is connected to a central portion of the rear surface 21 of the door panel 21, and the second connection surface 24b is connected to a central portion of the front plate 22a of the receiving portion 22.

The coupling portion 24 further includes an outer surface 24c formed between the first coupling face 24a and the second coupling face 24 b.

Referring to fig. 10 to 13, in a state where the door panel 21 and the receiving portion 22 are connected by the connecting portion 24, since the cross-sectional area of the connecting portion 24 is smaller than the surface area of the rear surface 21a of the door panel 21 and the surface area of the front plate 22a of the receiving portion 22, the rear surface 21a of the door panel 21, the front plate 22a of the receiving portion 22, and the outer surface 24c of the connecting portion 24 enclose the recess portion 25.

A seal member 23 is provided in the recess 25. The sealing member 23 surrounds the connecting portion 24 and is in close contact with an outer surface 24c of the connecting portion 24.

At this time, a part of the sealing member 23 is inserted into the recess 25 and can be closely attached to the bottom surface of the recess 25.

The portion of the sealing member 23 inserted into the recess 25 overlaps the accommodating portion 22 in the front-rear direction. That is, the sealing hollow portion 231 of the sealing member 23 is located in the recessed portion 25, and a portion of the sealing member 23 close to the sealing hollow portion 231 is also located in the recessed portion 25. Therefore, the accommodating portion 22 overlaps with a part of the sealing member 23 in the front-rear direction. In particular, the front plate 22a of the accommodating portion 22 overlaps with a part of the sealing member 23.

As described above, the sealing member 23 may have the first contact surface 23a ' that contacts the rear surface 21a of the door panel 21, the second contact surface 23b ' that contacts the outer surface 24c of the connecting portion 24, and the fourth contact surface 23d ' that contacts the convex inner surface 12a of the convex panel 12.

A pressing plate 26 is also provided in the recess 25. The pressing plate 26 is in close contact with the third contact surface 23 c' of the sealing member 23.

At this time, a part of the pushing plate 26 may be inserted into the recess 25.

The portion of the pushing plate 26 inserted into the recess 25 overlaps the accommodating portion 22 in the front-rear direction.

The pressing plate 26 has a hollow pressing hollow portion 261. The pressing hollow 261 is located in the recess 25. A portion of the pressing plate 26 close to the pressing hollow portion 261 is also located in this recessed portion 25. Therefore, a part of the pushing plate 26 overlaps with the accommodating portion 22, particularly with the front plate 22a of the accommodating portion 22, in the front-rear direction.

The size of the sealing hollow 231 may substantially coincide with the size of the pushing hollow 261. The connecting portion 24 penetrates the sealing hollow portion 231 and the pressing hollow portion 261. The pressing hollow portion 261 may be located between the sealing hollow portion 231 and the front plate 22a of the accommodating portion 22.

The pressing hollow portion 261 may have a predetermined interval from the coupling portion 24 in order to avoid friction with the coupling portion 24 during the movement of the pressing hollow portion 261 in the recess 25. Of course, it is also possible to apply lubricant between the pressing hollow portion 261 and the connecting surface 24a of the connecting portion 24.

The first fastening surface 23a 'is substantially parallel to the third fastening surface 23 c', and the second fastening surface 23b 'is substantially parallel to the fourth fastening surface 23 d'. The first fastening face 23a 'is substantially perpendicular to the second fastening face 23 b'. Therefore, the cross section of the sealing member 23 in the front-rear direction may be formed in a substantially quadrangular shape.

In a state where the drawer type storage box 20 closes the housing 10, the pressing plate 26 is located between the sealing member 23 and the pressing surface 11 c.

The pressing plate 26 is in close contact with one surface of the sealing member 23 in the recess 25. Here, a surface of the sealing member 23 that is in close contact with the pressing plate 26 is referred to as a third contact surface 23 c'.

The pushing plate 26 moves in the front-rear direction in the recess 25.

The pressing plate 26 has a first pressing surface 26a bonded to the third abutting surface 23 c' of the sealing member 23 and a third pressing surface 26c a part of which is pressed by the above-described pressing surface 11 c.

In a state where the drawer type storage box 20 closes the housing 10, the third pressing surface 26c of the pressing plate 26 is pressed by the pressing surface 11c of the wall portion 11, whereby the first pressing surface 26a of the pressing plate 26 presses the third abutting surface 23 c' of the sealing member 23 to protrude the sealing member 23 toward the convex inner surface 12a of the above-mentioned convex plate 12.

In the present embodiment, the first pressing surface 26a of the pressing plate 26 and the third contact surface 23 c' of the sealing member 23 are bonded together by an adhesive or the like. A part of the urging plate 26 is located in the recessed portion 25 and a part is exposed outward from the recessed portion 25, so that the pressing surface 11c moves the entire third pressing surface 26c of the urging plate 26 by pressing the exposed part of the urging plate 26. To this end, the pushing plate 26 may be formed of a hard material, such as a metal plate or a hard plastic.

A portion of the third pressing surface 26c of the pressing plate 26 inserted into the recessed portion 25 may be referred to as a third in-groove pressing surface 26c1, and a portion exposed from the recessed portion 25 and pressed by the pressing surface 11c may be referred to as a third out-groove pressing surface 26c 2.

In order to move the pressing plate 26 within the recessed portion 25 while being pressed by the pressing surface 11c, the second pressing surface 26b of the pressing plate 26 close to the connecting portion 24 is spaced from the outer surface 24c of the connecting portion 24 by a predetermined distance, thereby preventing friction from being generated between the second pressing surface 26b of the pressing plate 26 and the outer surface 24c of the connecting portion 24 during the movement.

The fourth pushing surface 26d of the pushing plate 26, which is away from the connecting portion 24, is spaced apart from the convex inner surface 12a of the convex plate 12 by a predetermined distance in a state where the drawer type storage box 20 closes the housing 10, whereby the pushing plate 26 can be prevented from colliding with the convex plate 12 during the closing of the drawer type storage box 20 to the housing 10.

When the drawer type storage box 20 is viewed from the rear, the pushing plate 26 protrudes outward from the accommodating portion 22.

In practice, during the process of inserting the drawer type storage box 20 into the inner space of the housing 10, the third pressing surface 26c of the pressing plate 26 is pressed by the pressing surface 11c of the wall portion 11 of the housing 10, so that the first pressing surface 26a of the pressing plate 26 presses the third contact surface 23c of the sealing member 23, at this time, the first contact surface 23a of the sealing member 23 is pressed by the rear surface 21a of the door panel 21, the second contact surface 23b of the sealing member 23 is pressed by the outer surface 24c of the connecting portion 24, and thus the fourth contact surface 23d of the sealing member 23 protrudes toward the protruding inner surface 12a of the protruding plate 12.

Therefore, the embodiment of the present invention can press the pressing surface 11c with a part of the pressing plate 26, and can press the entire sealing member 23 to be elastically deformed. Specifically, the pressing surface 11c presses only the third groove outward pushing surface 26c1 of the pushing plate 26, and the third groove outward pushing surface 26c1 moves toward the sealing member 23 and presses the third contact surface 23c of the sealing member 23. At this time, the fourth close surface 23d of the seal member 23 protrudes toward and closely contacts the convex inner surface 12a of the convex plate 12.

In the above embodiment, the recessed portion 25 is formed by the connecting portion 24, the accommodating portion 22, and the door panel 21. However, if necessary, the recessed portion 25 may be formed only in the front plate 22a of the housing portion 22. The purpose of forming the recessed portion 25 is to insert a part of the sealing member 23 and a part of the urging plate 26 into the recessed portion 25 so that the part of the sealing member 23 and the part of the urging plate 26 overlap the housing portion 22 in the front-rear direction, particularly overlap the front plate 22a of the housing portion 22. Thereby, while a part of the sealing member 23 and a part of the urging plate 26 are inserted in the recessed portion 25, the other part of the sealing member 23 and the other part of the urging plate 26 can be exposed to the outside from the recessed portion 25, and the exposed part of the urging plate 26 is pressed by the pressing surface 11c, whereby the entire part of the urging plate 26 is urged toward the sealing member 23, the entire part of the sealing member 23 is pressed, and the pressing can be made toward the convex inner surface 12a of the convex plate 12. Therefore, the thickness of the wall portion 11 is ensured, and a good sealing effect can be achieved.

The food storage device according to the embodiment of the present invention may further include a close fitting member for allowing the drawer-type storage box 20 to be closely fitted to the housing 10 after the drawer-type storage box 20 is inserted into the inner space of the housing 10.

For example, the close contact member may include a first magnet 31 disposed inside the rear wall of the housing 10 and a second magnet 32 disposed outside the rear plate portion 22b of the receiving portion 22 of the drawer type storage box 20.

The first magnet 31 and the second magnet 32 are opposite in magnetism, and therefore the first magnet 31 and the second magnet 32 attract each other when they approach each other.

The second magnet 32 may be an electromagnet, and the magnitude of the current flowing through the electromagnet is controlled to control the attractive force between the first magnet 31 and the second magnet 32.

After the drawer type storage box 20 is inserted into the inner space of the housing 10, the drawer type storage box 20 is closely attached to the housing 10 by the attraction force between the first magnet 31 and the second magnet 32. Thereby, the sealing member 23 is pressed by the suction force to be elastically deformed, and a sealing effect can be obtained.

The positions of the first magnet 31 and the second magnet 32 are not limited, and the first magnet 31 may be provided between the sealing member 23 and the door plate 21, and the second magnet 32 may be provided on the pressing surface 11 c. As long as one magnet is disposed on the drawer-type storage box 20 and the other magnet is disposed on the housing 10, the attractive force generated between the two magnets can tightly attach the drawer-type storage box 20 to the housing 10, and thus any position of the magnets is not limited.

In the case where the food storage device 1 of the present invention is a refrigerator in which a door is rotated by a hinge, the structure is substantially the same as that of the above-described embodiment except that the door is coupled to the case 10 by a hinge.

In the case of a refrigerator with a revolving door, a storage case for storing beverages or the like may be projected from the rear of the door panel 21, or a heat insulating layer having a heat insulating function may be provided. Here, both the storage case and the insulating layer may be the projection 22 of the present invention.

In the case of a refrigerator with a swing door, of the two magnets, the first magnet 31 may be disposed on the pressing surface 11c of the wall portion 11 of the case 10, and the second magnet 32 may be disposed behind the door panel 21. In a state where the door closes the housing 10, the two magnets may attract each other.

Although not shown, the food storage device of the present invention may further include a refrigeration cycle system. A compressor, a condenser, an evaporator, a valve, etc. constitute a refrigerating cycle system to provide a refrigerating environment to the inner space of the casing 10.

The present invention has been described above by way of a modification of the embodiment. It should be understood that the above-described embodiments or modifications are only a part, not all, of the present invention, and the described embodiments or modifications are only for explaining the present invention and are not intended to limit the present invention. All other embodiments or modifications which can be obtained by a person skilled in the art without any inventive step based on the above embodiments or modifications belong to the protection scope of the present invention.
