The present invention relates to a refrigerator, and more particularly, to a cold air flow path structure inside a refrigerator. More particularly, the present invention relates to a cold air flow path structure of a refrigerator which can be used more efficiently and efficiently by allowing cold air supplied to an ice making device to be used more efficiently.

The ice making device is a device in which ice is manufactured, and is installed inside the refrigerator so that ice is manufactured to an appropriate size and supplied to the user. Recently, as the user's taste is advanced, the ice maker is fixedly mounted inside the refrigerator. The ice maker includes an ice maker in which ice is manufactured, an ice bank in which ice is accumulated and stored, and an ice dispenser for supplying a user with an appropriate amount and size of ice contained in the ice bank. In general, the ice making apparatus is generally installed in the freezing compartment to supply the own cold air of the freezing compartment to perform ice making.

Meanwhile, a general refrigerator is divided into a freezer compartment in which food is stored frozen and a refrigeration chamber in which food is stored for a long time in a low temperature environment of an image. In addition, the refrigerating compartment is formed to be relatively large compared to the freezing compartment, and is formed in a structure that ensures a wide space for storing food at a low temperature.

However, when the ice making apparatus is installed in the freezer as in the conventional refrigerator, the ice making apparatus occupies a large amount of the inner space of the narrow freezer compartment, so that the inner space of the freezing compartment becomes too narrow.

In addition, since at least a part of the ice making apparatus is placed in the actual internal space of the freezer compartment, the internal space of the freezer compartment is further narrowed.

 The present invention is proposed to improve the above-mentioned problems, and an object of the present invention is to propose a cold air flow path structure of a refrigerator, which enables the entire internal space of the refrigerator to be used more efficiently.

In addition, it is an object of the present invention to propose a cold air flow path structure of the refrigerator that can be used to expand the space of the refrigerator by making the internal space in which the ice making device can be installed in a place separate from the space in which the food is actually accommodated. It is done.

The cold air flow path structure of the refrigerator according to the present invention for achieving the above object is an ice-making chamber is placed in the refrigerating chamber, the ice is produced by the cold air supplied from the outside; And a connection duct extending from the ice making chamber and having an exhaust port to allow cold air of the ice making chamber to flow into the refrigerating chamber.

According to another aspect, a refrigerator air flow structure of a refrigerator of the present invention includes an ice making device installed in a refrigerating compartment door; A connection duct through which cold air is guided from the ice making device to the refrigerating chamber; And a suction passage through which cold air flows into the ice maker from an evaporator or a freezing chamber.

According to the present invention as proposed, there is an advantage that the internal space of the refrigerator can be used more efficiently. In particular, by securing more internal space of the freezer compartment, it is possible to obtain the advantage that the convenience of use of the consumer is enhanced.

Hereinafter, with reference to the drawings propose a preferred embodiment of the present invention. However, the spirit of the present invention is not limited to the embodiments presented, and those skilled in the art who understand the spirit of the present invention can easily add, change, delete, or add other embodiments within the scope of the same idea. I would be able to suggest. However, such embodiments will also be included within the spirit of the invention.

FIG. 1 is a perspective view of a refrigerator to which the idea of the present invention is applied and shows a bottom freezer-type refrigerator in which a refrigerating room and a freezing room are positioned above and below, respectively.

The refrigerator 1 includes a freezer compartment door 2 formed at an approximately lower portion of the front side of the refrigerator main body, and a refrigerator compartment door 3 formed at an upper side thereof. An ice dispenser 17 is formed on the front surface of the refrigerating compartment door 3 to supply ice.

Of course, an ice maker having a predetermined structure for supplying ice to the ice dispenser 17 is provided inside the door. Specifically, an ice maker in which ice is directly manufactured and a large amount of ice produced in the ice maker are stored. It is an ice bank and a dispenser in which the ice stored in the ice bank is supplied in an appropriate size and amount.

2 shows a state in which the door of the refrigerating compartment is open. Referring to FIG. 2, an ice making chamber 5 is placed on the upper side of the inside of the refrigerating compartment door 3, in which ice is manufactured, and a connection duct 11 in which cold air of the ice making chamber 5 is guided into the refrigerating compartment. do.

In this way, since the ice-making chamber 5 is formed in the refrigerating chamber, the effect of widening the inner space of the narrow freezing chamber can be obtained. And, since the ice making chamber 5 is formed in the refrigerating chamber door 3, the actual space in which food is accommodated in the refrigerating chamber is further expanded.

In detail, the ice making chamber 5 has an inner surface of the ice making chamber 5 which is opened and closed so that cold air is smoothly guided to the connection duct 11 and on one side of the ice making chamber 5. And an ice making chamber suction port 8 formed at the other side of the ice making chamber 5 so as to be connected to the high inner discharge port 6 to supply cold air to the ice making chamber 5. An ice making chamber discharge port 9 through which cold air used in the ice chamber is recovered to the inside of the high chamber is formed. Of course, the high inner discharge port 6 and the high inner suction port 7 is a portion through which the cool air of the evaporator flows in / out of the evaporator so that the cool air is supplied to the ice making chamber 5 by a predetermined cold air passage structure passing through the inside of the refrigerator. do. The ice-making chamber cover 10 allows the internal space of the ice-making chamber 5 to be separated from the interior of the refrigerating chamber, so that cold air is smoothly guided to the connection duct 11.

In detail, a part of the connection duct 11 is opened to form an exhaust port 14 through which cold air that freezes water in the ice making chamber 13 is discharged to the refrigerating chamber.

The operation or operation of the ice making chamber 5 and the connection duct 11 will be briefly described with reference to the above-described configuration. First, the cold air of the refrigerator is supplied into the ice making chamber 5 through the ice making chamber suction port 8 so that ice is produced in the ice making chamber 5. In addition, although the cool air used for the operation of the ice making chamber 5 is sucked back into the inside through the ice making chamber discharge port 9, most of the cold air is supplied to the refrigerating chamber through the connection duct 11 to be refrigerated. Allow food to cool inside.

In this way, the cold air once used for the operation of the ice making chamber 5 is supplied to the refrigerating chamber again, even though the cold air used for the ice making once in the ice making chamber 5 remains cold. Because there is. This is because the food in the refrigerating compartment can be cooled more quickly by the cold energy. Of course, it can be easily guessed that the cold air used through the ice making chamber 5 is lower than the cold air inside the refrigerating chamber.

3 is a cross-sectional view taken along line II ′ of FIG. 2, and details of the cold air flow channel structure of the refrigerator of the present invention will be described in detail with reference to this drawing.

Referring to FIG. 3, an ice maker is placed on an upper side of the refrigerating compartment door 3, and a connection duct 11 is formed under the ice maker.

In detail, the ice maker includes an ice maker 15 in which ice is manufactured, an ice bank 16 placed under the ice maker 15, in which ice is stored, and ice stored in the ice bank 16 in an appropriate size. And an ice dispenser 17 to be supplied to the user in an amount. In addition, the cold air of the ice making chamber (5) flows downward by its own weight and flows into the connection duct (11), and the cold air flowing inside the connection duct (11) into the inside of the refrigerating chamber by the exhaust port (14). The food is discharged and accommodated in the refrigerating compartment to cool down.

Referring to the cold air flow path structure of the refrigerator according to the present invention described above, after the cool air generated in the evaporator (not shown) forming the refrigeration system is supplied to the ice making chamber (5) to freeze the water, the connection duct 11 Through the discharged into the inside of the refrigerating compartment, it can be seen that the food in the refrigerating compartment is stored at a low temperature. And, if the temperature of each part is explained, it can be guessed that the temperature of the ice-making chamber 5 is the lowest, and the temperature of the refrigerating chamber is made a little higher than that.

In addition, the amount of cold air flowing through the connection duct 11 and the amount of cold air flowing through the ice making chamber discharge port 9 are controlled so that the ice making chamber discharge port 9 and / or the connection duct 11 are controlled. The damper 12 may be further formed. In the drawing, a damper 12 is installed at the inlet portion of the connection duct 11. In the state in which the damper 12 is closed, cold air is re-introduced to the evaporator side through the ice making chamber outlet 9. In the state where the damper 12 is open, cold air is discharged into the refrigerating chamber through the connection duct 11 and the exhaust port 14. By this operation, the temperature state inside the refrigerating compartment may be adjusted.

 In some cases, in the state in which the ice making chamber discharge port 9 and the high inner suction port 7 are not formed, all the cool air is guided to the connection duct 11 so that the inside of the refrigerating chamber is discharged through the exhaust port 14. It can also be kept low temperature alone.

FIG. 4 is a cross-sectional view taken along line II-II 'of FIG. 1 and illustrates the flow path of the entire refrigerator with reference to this drawing.

The freezer compartment 22 is placed below the refrigerator 1, the refrigerating compartment 21 is placed above the freezer compartment 22, and the machine compartment 27 is positioned at the rear side of the freezer compartment 22 so that the cold To be created. Of course, the compressor 23, the condenser 24, and the evaporator 25 are placed in the machine room 27 and the position adjacent to the machine room 27 so that the cold air is supplied to the refrigerating chamber 21 and the freezing chamber 22 after the cold air is made. do.

Meanwhile, the cold air produced by the evaporator 25 is blown by the blower fan 26 and guided to the ice making chamber 5 through the suction duct 28 so that ice is made inside the ice making chamber 5. . The cold air remaining after ice is formed in the ice making chamber 5 is supplied to the refrigerating chamber 21 through the connection duct 11 or to the freezing chamber 22 through the discharge duct 29. Can be regressed. In addition, an end of the suction duct 28 forms the high inner discharge port 6, and an end of the discharge duct 29 forms the high inner suction port 7.

In addition, a low temperature atmosphere may be formed in the refrigerating chamber by the cold air supplied to the refrigerating chamber 21 through the exhaust port 14 of the connection duct 11.

In addition, as another feature of the present invention, by allowing the ice maker 15 to be fixed to the refrigerating compartment door 3, an internal space of the refrigerating compartment may be obtained more efficiently. And since the ice maker 15 is attached to a door, the air used for cold air of the ice maker 15 can spread rapidly to the large space of the refrigerating chamber 21. As shown in FIG. This is because the cold air discharge port may be blocked by food in a general refrigerator compartment. In this way, in order to allow the cold air to spread quickly and smoothly into the refrigerating chamber, a plurality of exhaust ports 14 are formed in a large area of the connection duct 11 in a relatively wide vertical direction.

 If the ice maker 15 is placed on a shelf inside the refrigerator compartment, since the inner space of the refrigerator compartment in which food is placed is reduced, it is not preferable. In the present invention, the ice maker 15 is more preferably formed by the door 3. Can be implemented.

In addition, the front of the door (3) is provided with a door handle (4) can be used when the user opens the door.

In the above description, the cold air flow path structure of the present invention has been applied to a bottom freezer-type refrigerator. However, the spirit of the present invention is not limited thereto, and the freezer compartment and the refrigerating compartment are respectively formed on the upper side and the lower side. A top mount type and a side by side type refrigerator in which a freezer compartment and a refrigerating compartment are formed at left and right sides may be conveniently applied. Hereinafter, the application of the present invention according to the form of the refrigerator will be described in detail.

In addition, after the ice is manufactured in the ice making chamber 35, the cold air may be discharged into the refrigerating chamber 32 through the connection duct 37 or returned to the freezing chamber 31 through the discharge-side flow passage 39. .

In addition, as described in the original embodiment, without the discharge side flow path 39 and the ice making chamber discharge port 42 being formed, all the cold air introduced into the ice making chamber 35 is guided to the exhaust port 43 so that the refrigerating chamber is provided. The internal food of (32) may be kept cold. Of course, at this time, food in the refrigerating compartment may be stored colder, and in some cases, without the need for a separate cold air inlet duct for discharging cold air into the refrigerating compartment, the inside of the refrigerating compartment by the cold air discharged from the exhaust port 43 You can also keep food cold.

In addition, an ice making chamber 55 is formed on the inner side of the refrigerating chamber door 54 to form ice, and a connection duct 57 is formed below the ice making chamber 55 to discharge cold air. . As described above, since the connection duct 57 is formed below the ice making chamber 55, the cool air of the ice making chamber 55 can be smoothly guided to the connection duct 57, and the connection duct ( By allowing the cold air of the ice-making chamber 55 to be discharged to a wide area through the exhaust port 63 processed in the 57, the entire internal space of the refrigerating chamber can be cooled quickly.

In addition, in order to allow the cool air to be supplied to the ice making chamber 55, an ice making chamber suction port 61 and an ice making chamber discharge port 62 are formed on the side surface of the ice making chamber 55, and the refrigerator with the refrigerator compartment door 64 closed. At the position of the refrigerator main body which is in contact with the main body, a suction side flow path 58 and a discharge side flow path 59 connected to the freezer compartment may be formed. The suction side flow path 58 is in contact with the ice making chamber suction port 61, and the discharge side flow path 59 is in contact with the ice making chamber discharge port 62, so that the cool air in the freezing chamber can smoothly flow into / out of the ice making chamber 55.
