At least the compressor is generally housed in the machine room 7 below the refrigerator.

In addition, the present invention further provides a plurality of configurations for allowing the vacuum pressure to be formed. In detail, a motor 5 and a vacuum pump 6 for placing a vacuum pressure are placed inside the machine room 7. In addition, the vacuum pressure of the vacuum pump 6 extends through the vacuum flow path 8 to the suction guide 12 formed on the front surface of the freezing chamber door 4 so that air is sucked through the suction guide 12. do. In addition, the vacuum flow path 8 may reach the suction guide 12 through the side wall of the refrigerator, the door hinge 10 of the refrigerator, and the inside of the freezer compartment 4. In addition, a valve 9 is formed on the vacuum flow path 8 to selectively shield the vacuum pressure of the vacuum pump 6.

In addition, an inlet portion of a vacuum container (see 20 in FIG. 3) of a predetermined shape is inserted into the suction guide 12 to transmit the vacuum pressure of the vacuum flow path 8 into the vacuum container (see 20 in FIG. 3). .

Further, below the suction guide 12, a shelf 11 for allowing the vacuum container 20 to be seated therein, and a hinge 13 for allowing the shelf 11 to rotate about the freezer compartment door 4. Is provided. By the hinge 13, when the shelf 11 is used, the vacuum container 20 can be laid down downward about the hinge 13, and when the shelf 11 is not used, the hinge 13 is centered. It is raised upwards. Therefore, when the shelf 11 is not used, it is possible to form the exterior of the freezer compartment door 4.

The operation to action of the food organ storage device of the refrigerator of the present invention as described will be described briefly. When the user wants to use the vacuum container 20, the vacuum container 20 in which food is accommodated is placed on the shelf 11, and then the vacuum of the inlet and the suction guide 12 of the vacuum container 20 is aligned. The container 20 is urged upwards. After that, the vacuum pump 6 is operated so that the vacuum pressure is transmitted to the vacuum vessel 20 through the vacuum flow path 8, and the air of the vacuum vessel 20 is drawn out to the vacuum pump 6 side by the vacuum pressure. A vacuum environment may be created inside the vacuum vessel 20 by going out.

Hereinafter, the configuration and operation of the present invention will be described in detail. 2 is a cross-sectional view taken along line II ′ of FIG. 1, and FIG. 3 is a view for explaining the operation of the present invention.

2 to 3, the suction guide 12 protrudes downward from an upper end surface of the recessed portion of the freezing compartment door 4, and the vacuum guide 20 is inserted into one side of the suction guide 12. A vessel sensor 14 for sensing is installed.

In addition, the vacuum container 20 has a main body 21 in which food is accommodated, and a door 22 to open and close one side of the main body 21. In addition, an insertion end 23 is formed at one side of the door 22 to be aligned with the suction guide 12, and an air passage 24 is arranged at the insertion end 23 to be aligned with the vacuum flow path 8. The check valve 25 is formed inside the air passage 24 to allow air to flow only in a direction in which the air inside the vacuum vessel 20 flows out.

The operation of the present invention with the proposed configuration will be described. First, when the user wants to store food in a vacuum state, the food is put into the main body 21 of the vacuum container 20 and then the door 22 is closed. Then, the shelf 11 is removed and the vacuum container 20 is placed on the upper side of the shelf 11 to prepare for use of the vacuum container 20.

Then, after the insertion end 23 and the suction guide 12 of the vacuum vessel 20 are aligned in the vertical direction, the vacuum vessel 20 is pushed upward. Then, the fact of insertion of the insertion end 23 is detected by the container sensor 14, and the detection signal is transmitted to the controller of the refrigerator to operate the motor 5 and the vacuum pump 6. Since the operation of the vacuum pump 6 is transferred to the vacuum vessel 20 through the vacuum flow path 8 and the air flow path 24, the air inside the vacuum vessel 20 is discharged to the vacuum flow path 8 and the vacuum container. 20 is in a vacuum state.

Then, after it is determined that a certain degree of vacuum pressure is applied to the inside of the vacuum container 20, the vacuum container 20 is removed so that the connection between the insertion end 23 and the suction guide 12 is released, and the container sensor 14 detects this to stop the operation of the motor 5 and the pump 6. In addition, since the air passage 24 is shielded by the check valve 25, the vacuum pressure inside the vacuum vessel 20 can be maintained firmly, and air cannot be introduced from the outside. When the vacuum container 20 is stored in the refrigerator in this state, the low temperature atmosphere of the refrigerator as well as the vacuum pressure of the vacuum container 20 itself are applied to the food contained in the body of the vacuum container 20. As it loses, food can be kept fresh longer.

On the other hand, the user may not know how much vacuum pressure is applied to the inside of the vacuum vessel 20 until the user becomes accustomed to some extent. Therefore, when a predetermined pressure sensor is provided on the vacuum passage 8 and the internal pressure on the vacuum passage 8 reaches a predetermined set pressure by the pressure sensor, the motor 5 and the vacuum pump 6 If the operation of) stops automatically, the user may use the vacuum container more conveniently.

On the other hand, in order to completely seal the interior of the vacuum vessel 20, the door 22 and the main body 21 is preferably sealed by a predetermined sealing member, the suction guide 12 and the air flow path ( It is preferable that the space between 24 is also sealed by a predetermined sealing member.

When the user wants to use the vacuum container according to the present invention described above, the vacuum pressure is conveniently applied to the vacuum container 20 by lifting upward while the vacuum container 20 is placed on the shelf 11. You can do that. In addition, even when a user incorrectly handles the vacuum container 20, the vacuum container 20 does not fall, but is safely placed on the shelf 11, thereby increasing the safety of the user. In order to enable such an operation, it is preferable that the shelf 11 is not opened more than 90 degrees with respect to the door of the refrigerator, and when the shelf 11 is closed, the shelf 11 is locked with respect to the refrigerator door. .

In the present embodiment, the shelf 11 is illustrated as being formed in the freezer compartment door 4, but the inventive concept is not limited thereto and may be formed on the sidewall of the refrigerator compartment door or the refrigerator. In addition, when the shelf 11 is inserted into the refrigerator door 4, the position may be fixed by a predetermined locking structure.

However, when the above embodiment is performed, there is an inconvenience in that the user must lift upwards while holding the vacuum container 20. A method for remedy this problem is presented in Example 2.

Example 2

Embodiment 2 according to the spirit of the present invention is in many respects the same as the first embodiment, the vacuum flow path 8 is formed so that the user can use more conveniently, food can be accommodated inside the shelf There is a difference in that the food receiving portion 34 is further formed.

4 is a cross-sectional view of the refrigerator door according to the second embodiment.

Referring to FIG. 4, since the shelf 31 and the hinge 32 for rotating the shelf with respect to the freezer compartment door 4 are formed in the same manner as in the first embodiment, detailed description thereof will be omitted.

However, a recess 33 is further formed to recess the inner portion of the shelf 31 to a predetermined depth so that the vacuum container 20 is seated at the correct position. In addition, the inside of the shelf 31, the food receiving portion 34 is protected by a predetermined case, and a plurality of cold air inlet formed in the case so that the cold air flows into the inside of the food receiving portion 34 The hole 35 is further formed.

In addition, the suction guide 37 is formed on the position guide 36 placed on the upper side of the shelf 31, the position guide 36 is rotatable in the vertical direction by the hinge 40, The suction guide 37 is formed at a position where the suction guide 37 touches the insertion end 23 of the vacuum container 20 when the position guide 36 is lowered.

In addition, since the seating portion 32 is formed in a shape corresponding to the lower portion of the vacuum vessel 20, the vacuum vessel 20 can be correctly placed at a predetermined position of the upper portion of the shelf (31). Therefore, the user does not have to work so that the position of the insertion end 23 and the suction guide 37 of the vacuum container 20 is correctly placed, and the vacuum container 20 is placed on the seating part 33. Thereafter, the vacuum pressure of the vacuum flow path 20 can be applied to the vacuum vessel 20 only by lowering the position guide 36 downward.

In addition, the vacuum flow path 8 is preferably formed to be flexible at least in the hinge 40 in order to enable rotation with respect to the position guide 36. In addition, in order to enable the user to conveniently operate the position guide 36, a handle 39 is formed on the upper portion of the position guide 36 so that the user's operation may be conveniently performed.

The container detection sensor 38 and the hinge 32, which are not described, have the same functions as described in the first embodiment.

When the user puts food in the vacuum vessel 20 and then places the vacuum vessel 20 on the shelf 31, the position of the lower side and the seating portion 33 of the vacuum vessel 20 may be accurately guided. Of course, the shelf 31 is withdrawn about 90 degrees to the outside of the freezer compartment door 4. After the vacuum vessel 20 is placed in the correct position on the shelf 31, the position guide 36 is lowered so that the suction guide 37 and the insertion end 23 are aligned with each other. In the state where the suction guide 37 and the insertion end 23 are aligned, the vacuum flow path 8 and the air flow path 24 are in a aligned state, and therefore, the user needs to work to find the correct position of the vacuum container 20. There is no. In addition, although the seating part 33 is illustrated as being formed in one layer, the present invention is not limited thereto, and a plurality of seating parts may be opened in a form in which another seating part 33 is formed inside the largest seating part 33. Subsequently, by being formed at the correct position, various kinds of vacuum containers 20 having different shapes and sizes may be placed on the shelf 31.

Thereafter, when the position guide 36 is lowered further, the vacuum vessel 20 is detected by the vessel sensor 38, and the air passage 24 and the suction guide 37 are sealed, so that the vacuum passage 8 The vacuum pressure inside the) is transferred to the inside of the vacuum flow path 8 so that the inside of the vacuum vessel 20 may reach a vacuum state.

The other description is the same as that described in the first embodiment.

However, the above-described embodiment has a disadvantage that only the vacuum container 20 of a specific size and shape can be used. In order to remedy this problem, a third embodiment is proposed.

6 is a cross-sectional view of a freezer compartment door according to a third embodiment of the present invention. 6 is the same as in the first and second embodiments in many respects, but differs in the way the suction guide 53 reaches the common machine 20. Hereinafter, only the differences will be described in detail.

At the end of the vacuum flow path (8) is formed a stretchable portion (52) freely stretchable to a predetermined length. In addition, the suction guide 53 formed at the end of the vacuum flow path 8 has a handle on one side of the suction guide 53 in order to be detachable from the freezer door 4 and to operate the suction guide 53. 55 is formed.

The handle 55 allows the user to pull out the freezing chamber door 4 while holding the suction guide 53. When the suction guide 53 is drawn out, the vacuum flow path 8 is extended by the expansion and contraction unit 52. May increase or decrease.

Reference numeral 54 is a container sensor, 50 is a shelf, 51 is a hinge.

Referring to FIG. 7, after the vacuum container is placed on the shelf 50, when the suction guide 53 is pulled out while holding the handle 55, the user pulls the suction guide 53 out of the suction guide 53. ) Can be moved. Then, the end of the suction guide 53 is aligned with the insertion end 23 of the vacuum container 20, and when a force is applied to the aligned end, the vessel sensor 54 detects the insertion of the insertion end 23 Thus, the operation of the vacuum pump 6 is started to apply the vacuum pressure.

Since the following operation is the same as described by the above-described embodiment, detailed description thereof will be omitted. However, after sufficient vacuum pressure is applied to the inside of the vacuum vessel 20, the suction guide 53 is removed from the vacuum vessel 20, and the handle 55 is pushed to the original position on the refrigerator door by using the handle 55. The portion 52 is moved in the contracted direction. Therefore, the suction guide 53 can be restored to its original position without external interference.
