The present invention relates to a refrigerator, which is a food long-term storage device of the refrigerator to allow food stored in the refrigerator to be kept fresh longer.

A refrigerator in a general sense is a device that allows a low-temperature environment to be created inside the gourd, so that food stored in the gourd is cooled to suppress propagation of bacteria in the food, thereby preventing food water from decaying. On the other hand, the environment in which bacteria are not propagated can be used in various ways, such as ultraviolet sterilization, the composition of the vacuum state, chemical sterilization, the composition of the drying environment, in addition to the method to be stored at a low temperature such as a refrigerator.

Briefly describing the food storage method, the ultraviolet sterilization is a high frequency ultraviolet light is reflected to destroy the structure of the cell wall of the bacteria to inhibit the growth of the bacteria to die, and the vacuum state so that the gas necessary for breeding the bacteria is scarce The environment is created so that the growth of bacteria is suppressed, and chemical sterilization is sprayed with chemicals in the environment where bacteria can grow, and the growth of bacteria is suppressed. It is a method of inhibiting the growth of bacteria because it is narrow and does not penetrate inside or there is no moisture essential for the growth of bacteria.

However, among the various methods described above, ultraviolet sterilization has a disadvantage in that it is harmful to the human body, and the composition of the dry environment has a disadvantage in that the taste of food is inferior to the intake of food. Ingestion is undesirable to apply to the refrigerator.

On the other hand, even if food is stored at a low temperature inside the refrigerator, it is generally known that food decays after a certain time. In addition, food poisoning may occur after eating food, believing that it is stored in the refrigerator. As such, it would be desirable to create a vacuum as a method for keeping food freshly stored for a longer time in addition to the low temperature atmosphere.

Under this background, the present invention proposes an apparatus for allowing food to be stored for a longer period of time by further creating a vacuum in an atmosphere in which food is refrigerated. Furthermore, the present invention proposes an apparatus which can further improve the usability of the refrigerator by keeping articles stored in a predetermined vacuum container so as to be kept fresh for a longer time.

An object of the present invention is to propose a food long-term storage device of the refrigerator to allow food to be stored for a longer period of time under the background described above.

In addition, it is an object of the present invention to propose a food long-term storage device of the refrigerator that can suppress the growth of bacteria in food to improve the reliability of the consumer.

In addition, an object of the present invention is to propose a long-term storage device for food in the refrigerator, which is safely provided inside the refrigerator, which can be used by the user more conveniently.

Food long-term storage device for a refrigerator according to the present invention for achieving the above object is a vacuum pump; An air suction port to which a vacuum pressure applied from the vacuum pump is applied and formed in the refrigerator door; And a vacuum flow path extending at least to the refrigerator door in order for the vacuum pressure applied from the vacuum pump to be applied to the air intake port.

Food and beverage storage device of the refrigerator according to another aspect of the present invention comprises a vacuum pump; A vacuum flow passage through which the vacuum pressure of the vacuum pump passes through the sidewalls of the refrigerator and the refrigerator door to reach the front of the refrigerator door; An air inlet formed of a rigid material formed at an end of the vacuum flow path; And a container receiving jig formed at a position adjacent to the air inlet to guide the position of the vacuum container in which the food is accommodated.

According to the present invention, the food stored in the refrigerator can be stored in a vacuum state in a low temperature atmosphere, so that the food can be stored more safely. In addition, since the vacuum state can be conveniently formed, the user's convenience may be improved.

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 pump 6 extends to the air inlet 11 formed at the front of the freezing chamber door 4 to allow the air to be sucked through the air inlet 11. In addition, a container support jig 12 is positioned at an adjacent outer portion of the air intake port 11 so that a predetermined vacuum container (see FIG. 3) is guided and seated in the air intake port 11. 12, a vessel detection sensor 13 for detecting the entry of the vessel is formed. In addition, unlike the soft vacuum flow path 8, the air inlet 11 is made of a rigid plastic material, it is preferable to ensure that the vacuum container is inserted safely.

In addition, the vacuum flow path 8 to which the vacuum pump 6 and the air intake port 11 are connected extends through the side wall of the refrigerator body 2 to the freezer compartment door 4. In particular, at the connection portion between the refrigerator main body 2 and the freezer compartment door 4, it is preferable that the refrigerator door 4 pass through a hinge that is fixed to the refrigerator main body 2. Further, a valve 9 is further formed on the flow path of the vacuum flow path 8 to block or open the flow of air passing through the vacuum flow path 8.

With reference to the configuration described above, the operation and operation of the long-term storage device according to the present invention will be briefly described. When the user places the inlet of the vacuum container 21 of a predetermined shape in a state aligned with the air inlet 11, the container sensor 13 detects the mounting of the vacuum container and the vacuum pump 6 is operated. . The vacuum pressure generated in the vacuum pump 6 is transferred to the container through the vacuum flow path 8 and the air inlet 11, and the air inside the container is sucked into the vacuum pump 6. In addition, the container receiving jig 12 is formed in the same shape as the inlet portion of the vacuum vessel to allow the user to conveniently place the vacuum vessel in the correct position.

Hereinafter, the configuration of the present invention will be described in detail.

FIG. 2 is a cross-sectional view taken along the line II ′ of FIG. 1, showing the configuration of a position adjacent to the air intake port 11 in detail, and FIG. 3 shows a cross-sectional view of the vacuum container.

2 and 3, the vacuum pressure applied by the vacuum pump 6 is applied to the air intake port 11 via the vacuum flow path 8. In addition, the container receiving jig 12 is formed in a shape corresponding to the insertion groove 24 of the vacuum container (see FIG. 3) at an adjacent position of the air inlet 11. Therefore, the container receiving jig 12 can be fitted to fit the insertion groove 24 accurately. Furthermore, since the front portion of the vacuum vessel 21 has a shape corresponding to the depression 14 recessed in the first half of the freezing chamber door 4, the air passages of the air intake port 11 and the vacuum vessel 21 ( 25 can be accurately seated in correspondence.

In addition, the container receiving jig 12 is provided with a container detecting sensor 13 that can detect the inlet of the vacuum container 21. In addition, an operation unit 10 capable of operating an operating state of the refrigerator may be further formed on the recess 14.

On the other hand, the vacuum container 21 includes a container main body 23 for receiving food and a container door 22 to cover the upper portion of the container main body 23. Of course, the container body 23 is protected by the container door 22, and a vacuum space is formed in the inside of the vacuum container 21 by the container door 22 and the container body 23. In addition, the soft sealing part having a predetermined shape is interposed between the container door 22 and the container body 23 so that the sealed state inside the vacuum container 21 can be maintained firmly.

In addition, the first half of the vacuum vessel 21, that is, the surface that is in contact with the air inlet 11 is formed to be configured to transmit the vacuum pressure. In detail, an air flow passage 25 formed at a position corresponding to the air intake port 11 to communicate the inside and outside of the vacuum container 21, a check valve 26 opening and closing the air flow passage 25, An insertion groove 24 is formed at a position corresponding to the container receiving jig 12.

In detail, the check valve 26 is a valve to allow only one-way movement with respect to the air flow path 25. The air inside the vacuum vessel 21 may escape to the outside, but the outside of the vacuum vessel 21. Air cannot enter inside. The check valve 26 may be applied to various shapes and configurations that have been proposed in the prior art. And, since the container receiving jig 12 is seated on the inner circumferential surface of the insertion groove 24, the position of the entire position of the vacuum vessel 21, in particular the position of the air flow path 25 of the air inlet 11 Can be guided accurately.

In addition, since the front portion of the vacuum vessel 21 with respect to the depression 14 has a corresponding shape, the entire vacuum vessel 21 can be placed in the correct position with respect to the freezer compartment door 4. Referring to FIG. 4, the seating shape of the front end portion and the recessed portion 14 of the vacuum container 21 can be accurately understood.

Referring to FIG. 4, after the container door 22 is closed in the state in which the food is accommodated in the container body 23, the vacuum container 21 is aligned with the depression 14.

When the vacuum container 21 and the recessed portion 14 are aligned, the positions of the container holder 12 and the insertion groove 24 are also aligned. However, even if it is not perfectly aligned, since it will be placed between each other in the adjacent position, the container receiving jigs 12 and the insertion groove 24 can be accurately aligned by moving only a small distance.

In addition, at the position where the container receiving jig 12 and the insertion groove 24 are aligned, the inner circumferential surface of the insertion groove 24 contacts the container detection sensor 13 to detect that the vacuum container 21 is inserted. Then, the detection signal of the container sensor 13 is transmitted to the control unit of the refrigerator to operate the vacuum pump 6 to apply a vacuum pressure to the vacuum flow path (8). When the vacuum pressure is applied to the vacuum passage 8, since the air inlet 11 and the air passage 25 are aligned, the check valve 26 is opened, and the air inside the vacuum vessel 21 is opened. The air flow passage 25 exits to the vacuum flow passage 8 side.

On the other hand, the contact surface of the air intake port 11 and the air flow path 25 can be more completely sealed by a soft sealing material such as rubber, etc., by being configured in this way, the air intake port 11 through the air flow path 25 Air delivered to) may enter the vacuum flow path 8 without leaking.

As described above, after it is recognized by the user that the air inside the vacuum vessel 21 has escaped into the vacuum flow passage 8 for a predetermined time, the vacuum vessel 21 is removed from the container holder 12, and the Store in the store.

On the other hand, in case the user cannot determine how much vacuum has been made, a predetermined pressure sensor may be placed on the vacuum flow path 8, and the pressure on the vacuum flow path 8 may be detected to be below a certain level. At this time, the operation of the vacuum pump 6 can be automatically stopped. Therefore, if the user does not apply the vacuum pressure after a certain time, it is determined that all the vacuum is made, it is enough to remove the vacuum container 21.

As described, the food long-term storage device of the refrigerator according to the present invention, by forming a predetermined vacuum pressure structure to which the vacuum pressure is applied to the door of the refrigerator, by applying a vacuum pressure to the vacuum container through the vacuum pressure structure The vacuum vessel can be used more conveniently.
