Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cooling duct and a refrigerator,

The present invention relates to a cold air duct provided in a refrigerator and a refrigerator provided with the cold air duct.

Generally, a refrigerator is a device for low temperature storage of food, and it is configured to be able to refrigerate or store food according to the condition of the food to be stored.

The interior of the refrigerator is cooled by the continuously supplied cold air, and this cold air is continuously generated by the heat exchange action of the refrigerant which repeatedly performs a cycle of compression-condensation-expansion-evaporation. The cold air supplied to the inside of the refrigerator is uniformly transferred to the inside of the refrigerator by the convection so that the food inside the refrigerator can be stored at a desired temperature.

In the refrigerator, the internal storage space is divided into a freezer compartment and a refrigerating compartment, and the food is frozen and refrigerated. A freezer compartment door and a refrigerator compartment door are separately provided for selectively shielding the freezer compartment and the refrigerating compartment.

In such a refrigerator, the ice-making chamber is generally provided in a storage space inside the freezing chamber. However, in this case, the storage space of the freezing compartment is narrowed, the user must open the door in order to take out the ice, and the water may overflow when the ice-making frame containing water is inserted into the freezing compartment of the freezing compartment.

In order to solve such a problem, recently, a refrigerator has been developed in which an ice maker is installed on a rear surface of a door, and a dispenser is provided on the front surface of the door so that a user can immediately take out ice.

Such modern refrigerators may also be provided with chilled ducts in the ceiling of the freezer compartment. The cool air duct directly transfers the cool air discharged from the grill at the rear of the freezer compartment to the ice maker to increase the amount of ice produced.

However, the above-described conventional techniques have the following problems.

The amount of cool air directly discharged into the freezer compartment is reduced because the cool air duct transfers part of the cool air discharged from the grill directly to the ice maker. Accordingly, since the amount of cool air circulating in the freezing compartment is reduced, heat transfer due to convection can not be smoothly performed. As a result, the temperature distribution inside the freezer compartment deteriorates.

Particularly, since the amount of cool air circulated by convection is small in both upper portions of the freezing chamber, it is impossible to obtain an appropriate refrigeration effect and the cool air discharged from the grill is not directly transmitted. do. As a result, the food stored at this location is not properly frozen.

In order to improve the deteriorated temperature distribution inside the freezer compartment, it is necessary to provide more cool air, thereby increasing the overall power consumption of the refrigerator.

Disclosure of Invention Technical Problem [8] The present invention has been proposed in order to solve the above-mentioned problems, and it is an object of the present invention to provide a refrigerator having a cool air duct for uniforming the temperature distribution inside the freezer compartment, .

According to an aspect of the present invention, there is provided a cold air duct comprising: a plate extending from a rear wall of a storage space of a refrigerator to an upper portion of an ice maker installed on a rear surface of a door; At least one main discharge port provided in the plate so that cool air is discharged to the ice making device, and at least one sub discharge port formed in the side frame so as to discharge cold air to the sides of the storage space.

According to another aspect of the present invention, there is provided a refrigerator including a main body provided with a refrigerator compartment or a freezer compartment, a door selectively shielding the refrigerator compartment or the freezer compartment, an ice maker provided on a rear surface of the door, And at least one first discharge port for discharging the cold air to the ice making device and at least one second discharge port for discharging the cold air toward the side of the freezing chamber or the freezing chamber, And a second discharge port.

According to the refrigerator having the cool air duct and the cool air duct according to the embodiment of the present invention, since the main discharge port is provided in the cool air duct, the amount of ice generated by the direct delivery of cool air to the ice maker is increased .

In addition, since the sub outlet is provided in the cool air duct, the cool air can be smoothly supplied to both sides of the storage space. Accordingly, the temperature distribution of the storage space is uniform, and the refrigeration efficiency of food stored on both sides of the storage space also increases.

In addition, there is no need to excessively produce cold air, thereby reducing the amount of power consumption.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a perspective view showing the inside of a refrigerator having a cool air duct according to an embodiment of the present invention.

Hereinafter, a side-by-side type refrigerator will be described as an embodiment to explain the concept of the present invention. However, the idea of the present invention is not limited to the illustrated double-sided refrigerator, but may be applied to a refrigerator in which a door basket is mounted, such as a top mount type in which a freezing chamber is located on the upper side and a bottom freeze type in which a freezing chamber is located on the lower side It can be applied to both.

1, a refrigerator 1 provided with a cool air duct according to an embodiment of the present invention includes a main body 10 partitioned into a refrigerating chamber 14 and a freezing chamber 15 by a barrier 11, A refrigerator compartment door 12 rotatably mounted on a front surface of the refrigerator compartment 10 for selectively opening and closing the refrigerator compartment 14 and a freezer compartment door 13 for selectively opening and closing the free compartment 15.

A plurality of shelves 16 and a storage box 17 are provided in the storage space inside the main body 10.

On the other hand, a plurality of baskets 18 for storing food are provided on the rear surface of the refrigerator compartment door 12 and the freezer compartment door 13.

An ice maker 300 for producing ice is mounted on the rear surface of the freezer compartment door 13 and a dispenser (not shown) for removing ice is mounted on the front surface of the freezer compartment door 13.

With this configuration, the storage space inside the refrigerator 1 can be efficiently used, and the inside of the refrigerator 1 can be made clean, thereby improving the satisfaction of the user.

Meanwhile, a cool air duct 200 for directly delivering the cool air provided from the rear surface of the freezer compartment to the ice maker 300 is provided on the ceiling of the freezer compartment 15. [

In detail, the cool air duct 200 is installed in the freezing compartment 15 from the rear wall of the freezing compartment 15 to allow the cool air to be discharged to the upper part of the ice maker 300 when the freezing compartment door 13 is closed. As shown in FIG.

With this configuration, since the cool air can be directly transmitted to the ice maker 300, the amount of ice generated in the ice maker 300 is increased.

The ice maker 300 and the multi-duct 200 may be provided not only in the freezer compartment door 13 and the freezer compartment 15 but also in the refrigerator compartment door 12 and the refrigerating compartment 14. [

3 is a perspective view of a cool air duct according to an embodiment of the present invention. FIG. 4 is a cross-sectional view of a cool air duct according to an embodiment of the present invention. FIG. 10 is a view showing the flow of cool air inside the freezing compartment.

2 to 4, the duct body of the cool air duct 200 includes a plate 201 forming a bottom surface and a side frame 202 forming a side surface.

In detail, the cold air duct 200 is provided with a foaming foam 250 for heat insulation in contact with the plate 201 and the side frame 202. A fixing part 220 for fixing the cool air duct 200 is formed on the upper surface of the plate 201.

The cool air duct 200 is fixed to a ceiling of the freezer compartment 15 by bolting a hole formed in the ceiling of the freezer compartment 15 with the fixing part 220. At this time, the front end of the plate 201 and the upper surface of the side frame 202 are formed in contact with the ceiling of the freezing chamber 15 to prevent the leakage of cold air.

Here, the method of fixing the cool air duct 200 may be modified, added, or deleted in a range where the ideas of the present invention such as hooks and slots are maintained, in addition to the method of using the bolts.

A grill 110 is provided on the rear wall of the freezing chamber 15, which is a cool air hole through which cool air escapes.

At this time, the latching bar 260 provided at the rear end of the cool air duct 200 is seated on the latching protrusion 120 protruded above the grill 110. A part of the grill 110 is fitted in the cold air inlet 270 defined by the space between the latching bar 260 and the plate 201.

The rear end of the cool air duct 200 is coupled to the rear wall of the freezer compartment 15 to prevent the cool air discharged from the grill 110 from flowing out to the outside. Accordingly, a part of the cool air discharged through the grill 110 flows into the cool air duct 200 through the cool air inlet 270.

Meanwhile, the grill 110 is provided with a grill 111 that is not fitted in the cool air inlet 270, so that cool air can be blown out into the freezing chamber.

A main discharge port 210 is provided at a position near the front end of the plate 201. The main discharge port 210 is provided to increase the amount of ice generated by directly transferring the cool air introduced through the grill 110 to the ice maker 300, .

The side frame 202 is formed with a sub-discharge port 230 for providing cool air above both sides of the freezing chamber 15. At this time, the plate 201 or the side frame 202 may further be provided with a guide 240 for guiding cool air so that the cool air can be flowed to the sub ejection orifice 230.

In detail, the guide 240 is formed to extend by a predetermined length so that the amount of cool air introduced into the main discharge port 210 is not too small. In addition, the guide 240 is preferably formed to have a predetermined curvature so that cold air can flow well without resistance.

For example, the guide 240 may be provided in a rib shape protruded from the upper surface of the plate 201 and curved in the direction of the sub-discharge port 230

Since the front end of the plate 201 and the upper surface of the side frame 202 are fixed to abut against the ceiling of the freezer compartment 15 in the cool air duct 200, The cold air that can not escape through the cooling air duct 230 may be accumulated in the vicinity of the front end of the cool air duct 200.

In order to solve such a problem, a front end discharge port may be formed near the front end of the cool air duct 200 to allow the accumulated cool air to escape.

Here, the main discharge port 210, the sub discharge port 230, and the front discharge port may be provided in a plurality of ways depending on the purpose thereof, and the shape and number thereof may be changed, added, or deleted within the range of the present invention. It will be possible.

In the refrigerator having the cool air duct and the cool air duct according to the embodiment of the present invention, since the cool air is directly transferred to the ice maker 300, the amount of ice generated is increased.

In addition, since the sub outlet 230 is provided, cold air can be discharged in the lateral direction of the cool air duct 200. Accordingly, since cool air is smoothly transmitted to the food 400 provided above both sides of the freezing chamber 15, the refrigeration efficiency of the food 400 is increased.

In addition, since the cold air is supplied not only through the grill 111 but also through the sub outlet 230, the amount of cold air circulating in the freezer chamber 15 is increased. Therefore, since the heat transfer by the convection is performed well, the temperature distribution inside the freezing chamber 15 becomes even.

As a result, it is not necessary to generate cold air, which is additionally required by the deterioration of the temperature distribution, so that the amount of power consumption can be reduced.

The scope of the present invention is not limited to the above-described embodiments, and variations, additions and deletions of the embodiments may be made within the scope of the present invention.
