In general, a refrigerator is a device that keeps food fresh for a period of time by keeping the inside of the refrigerator at a low temperature as the refrigerant performs compression, condensation, expansion, and evaporation cycles.

Hereinafter, a description will be given of a general refrigerator through the attached FIG. 1.

The refrigerator 1 has a large amount of heat exchanged from the cold air or the evaporator 4 of the freezer compartment 2 and the freezer compartment 2 in which the cold air heat-exchanged by the evaporator 4 directly flows in and maintains an internal temperature of about -18 ° C. Cold air is introduced into the refrigerating chamber (3) that maintains the internal temperature of about 0 ~ 7 ℃.

At this time, the upper portion of the evaporator (4) is provided with a cold air circulation fan (5) for forcibly circulating the cold air generated through the evaporator (4) to the freezing chamber (2).

The freezer compartment 2 and the refrigerating compartment 3 are partitioned up and down by the barrier unit. The cold air having a high temperature is circulated to the evaporator 4 while circulating the freezer compartment 2 and the refrigerator compartment 3 inside the barrier unit. A freezer compartment cold air circulation passage 8 and a refrigerating compartment circulation passage 9 are circulated.

In addition, a discharge cold air duct 6 in which cold air heat-exchanged through the evaporator 4 is discharged directly to the refrigerating chamber 3 is provided on the rear surface of the refrigerating chamber 3.

Hereinafter, a refrigerator container according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the sealing structure of the storage container for a refrigerator according to the first embodiment of the present invention will be described with reference to FIGS.

The refrigerator 200 includes a chamber 210 in which a fixing rail 211 is installed at a side surface of the refrigerator, and a container 220 which is installed in the chamber 210 and has a predetermined storage space and is drawn out in a drawer type. It is configured to include.
At least one surface of the chamber 210 is formed to be opened, and an edge of the opened portion of the chamber 210 is hereinafter referred to as an inlet 212.

The chamber 210 forms a space for accommodating the storage container 220, and fixed rails 211 are installed at both sides of the interior of the chamber 210 in the front and rear directions. It is formed, the fixed rail 211 is provided on both inner sides of the space.

At this time, the edge of the inlet portion 212 of the chamber 210 is preferably formed with a vertical surface 212a, the inside is chamfered to form an inclined surface 212b.

On the other hand, the storage container 220 is composed of a body 221 having a predetermined storage space and the cover 222 capable of selectively sealing and releasing the storage container 220.
Here, the vertical surface 212a is preferably formed perpendicular to the opening and closing direction of the cover 222, as shown in Figure 3a to 4d.

At this time, the body 221 is formed with a predetermined space for accommodating food and the like, the outer surface is provided with a moving rail 223 to correspond to the fixed rail 211 of the chamber 210.

On the other hand, the cover 222 is configured to include a first sealing member 225 and the second sealing member 226 to contact the inlet 212 of the chamber 210 to seal.

In this case, the cover 222 has a rib 224 vertically formed in the inner space toward the container 221 along the circumference of the inner surface, the ventilation hole 222a is formed on one side of the cover 222.

In addition to the vent hole 222a, the vacuum release bar 222b is provided to allow the vacuum state and release of the body 221 by selectively inserting and removing the vent hole 222a.

Meanwhile, the sealing members 225 and 226 are formed along the circumference of the inner surface of the cover 222.

In addition, the sealing members 225 and 226 may include a first sealing member 225 that contacts and seals the inner surface 212b of the inlet portion 212 of the chamber 210, and an edge of the inlet portion 212 of the chamber 210. And a second sealing member 226 that contacts and seals the outer surface 212a.

The first sealing member 225 is formed along the circumferential surface at an end thereof substantially upward of the rib 224.

In addition, the second sealing member 226 may be integrally formed along the inner edge surface of the cover 222 so as to correspond to the vertical surface 212a of the chamber 210 spaced apart from the rib 224 by a predetermined interval. Is formed.

At this time, the second sealing member 226 is preferably made thicker than the first sealing member 225.

This is to provide an optimal sealing effect by preventing the first sealing member 225 from excessively entering the chamber 210.

In addition, the material of the first sealing member 225 and the second sealing member 226 is preferably made of a silicone rubber material which is harmless to the human body and maintains excellent adhesion even at low temperatures.

By the above-described configuration, the operation and effect of the sealing structure of the storage container for a refrigerator according to the first embodiment of the present invention will be described with reference to FIG. 3.

First, the movable rail 223 installed on the outer surface of the body 221 is mounted to the fixed rail 211 installed on the inner surface of the chamber 210 so that the storage container 220 slides along the fixed rail 211. Optionally open and close.

At this time, when the storage container 220 is pushed toward the chamber 210 to press the cover 222 to the inlet 212 of the chamber 210, the first sealing member 225 is the inlet of the chamber 210 The part 212 comes in close contact with the oblique surface 212b preferentially.

At this time, the first sealing member 225 is made of a flexible material such as silicone rubber, the end of the first sealing member 225 is naturally bent while touching the inclined surface (212b) of the chamber 210 and evenly selected Primary sealing is achieved with surface contact.
At this time, the end of the first sealing member 225 is preferably made to face the outside of the chamber 210 as shown in Figure 3c. The reason for this is that the first sealing member 225 is further brought into close contact with the inclined surface 212b of the chamber by the pressure of air introduced between the second sealing member 226 and the inlet part 212, thereby further sealing. This is to ensure that it is done.

Meanwhile, at the same time as the primary sealing is made, the second sealing member 226 is in close contact with the vertical surface 212a of the inlet portion 212 of the chamber 210.
In this case, the second sealing member 226 is preferably in contact with the direction perpendicular to the vertical surface 212a, as shown in Figure 3a to 4d. This is to prevent friction from occurring when the second sealing member 226 contacts the inlet portion 212 so that the user may have a softer feeling of operation when opening and closing the cover 222.

Next, it is preferable to create a vacuum state by sucking air in the storage container 220 with a vacuum device (not shown) connected to one side of the chamber 210.

At this time, the inside of the storage container 220 is in a vacuum state because the vacuum release member 222b is inserted and sealed in the vent hole 222a formed at one side of the cover 222.

At this time, the pressure is lowered while being in a vacuum state in the storage container 220 and the second sealing member 226 fixed to the cover 222 is contracted so as to press the vertical surface of the chamber 210 to be in close contact with each other. This results in a tighter seal.

As a result, foodstuffs, etc., stored in the vacuum receiving container 220 may be kept fresh for a longer period of time.

On the other hand, the process of opening the storage container 220 for taking out food, etc. is as follows.

First, the inside of the storage container 220 in a vacuum state is released to the opening of the storage container 220. Accordingly, the vacuum releasing member 222b inserted into the vent hole 222a of the cover 222 is opened. Open to release the vacuum inside the storage container 220.

As a result, the external air pressure and the internal air pressure of the container 221 are equal to each other so that the food container in the storage container 220 can be taken out by easily opening the storage container 220.

Meanwhile, the sealing members 225 and 226 at the time of closing the storage container 220 and the chamber 210 have a close contact with the vertical surface 212a and the inclined surface 212b formed at the inlet 212 of the chamber 210. do.

When there is no section in which the inlet portion 212 of the chamber 210 is rubbed when the container 220 is opened after the vacuum is released, the user may easily open the container 220 without feeling friction.

On the other hand, the sealed structure of the storage container for a refrigerator according to the second embodiment of the present invention will be described with reference to FIG.

For reference, the same components as in the first embodiment of the present invention will be denoted by the same reference numerals and detailed description thereof will be omitted.

In the first embodiment of the present invention described above, two sealing members separated from each other are sealed at different positions, but in the second embodiment of the present invention, the sealing members are integrally formed. .

As can be seen through Figure 4, the sealing member 300 is formed in the close contact portion 301 to form a predetermined thickness.

In addition, the lower portion of the sealing member 300 is formed with an extension 302 extending inclined by a predetermined length to the inside of the chamber 210.

In this case, it is preferable that at least one or more sub-sealing members 303 are formed in the chamber 210 from the extension part 302.

Referring to the operation and effect of the above-mentioned sealing member 300 is as follows.

When pushing the cover 222 to the inlet 212 of the chamber 210 while pushing the storage container 220 in the direction of the chamber 210, the close contact portion 301 of the sub-sealing member 303 is chamber 210 The inlet portion 212 is in close contact with the vertical surface (212a) and the sub-sealing member 303 is bent naturally to be in close contact with the inclined surface (212b) of the chamber 210 evenly.

Thus, the first sealing is made by the sealing member 300, and at this time, the air remaining in the receiving container 220 is sucked by the vacuum apparatus (not shown) to be completely sealed and the secondary sealing is made. The inside is vacuumed.

Thereby, various foodstuffs etc. can be kept fresh for a long time.
