A Refrigerator

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a refrigerator, and more particularly, to a refrigerator which can efficiently perform cooling of a freezer compartment and uniform the temperature distribution inside the freezer compartment.

Generally, a refrigerator is divided into a refrigerator and a freezer to store and store food. The refrigerating chamber is maintained at a temperature of approximately 3 to 4 ° C for fresh and long-term storage of the food, and the freezing chamber is maintained at a sub-zero temperature for storage of the food in the frozen state.

Background Art [0002] In a conventional refrigerator, a freezer compartment is generally provided at an upper portion of a refrigerator compartment. [0004] Recently, a large-sized refrigerator with a large capacity has been developed, and a refrigerator compartment and a freezer compartment are provided side by side (Side by side type, below-door type) refrigerators are gaining popularity.

1, the freezing chamber 130 is located on the left side of the main body 110, and the freezing chamber 140 is located on the right side of the freezing chamber 130. A partition wall 115 is vertically disposed between the freezing chamber 130 and the refrigerating chamber 140. The freezing chamber 130 and the refrigerating chamber 140 are opened and closed by respective doors 121 and 123 rotatably coupled to the main body 110.

2, an evaporator 107 is installed at the rear of the freezing chamber 130. The evaporator 107 absorbs the heat inside the freezing chamber 130 and evaporates it, thereby keeping the inside of the freezing chamber 130 at a zero temperature.

For this purpose, a cool air discharge port 113a through which the cool air can be discharged from the evaporator 107 is formed in the upper portion of the freezing chamber 130. The cold air around the evaporator 107 is forcedly blown into the blowing fan 112 and discharged to the freezing chamber 130 through the cool air discharge port 113a.

At this time, the cool air discharged from the cool air discharge port 113a moves downward in a parabolic shape in the horizontal direction as indicated by the arrow, and circulates in the freezing chamber 130. [ The cold air having circulated and increased in temperature is sucked into the cold air inlet 113b formed in the lower portion of the freezing chamber 130 and then sent to the evaporator for cooling.

However, in the refrigerator having the above-mentioned cool air circulation structure, the temperature of the cold air discharge port 111a region where cold air is discharged and the region of the cold air intake port 113b which is re-suctioned, that is, the temperature of the uppermost end of the freezing chamber, I go.

This suggests that the distribution of the temperature inside the freezer compartment may not be uniform, and therefore, there may be differences in the refrigerating performance of each part of the freezer compartment.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a refrigerator which can uniformly improve the freezing performance of food placed on a shelf or a drawer by allowing the supply of cool air to the inner space of the freezing chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 3 is a perspective view of a refrigerator according to an embodiment of the present invention, FIG. 4 is a side sectional view showing a freezer compartment area of FIG. 3, FIG. 5 is a side perspective view of the cold air discharge duct of FIG. Is a planar perspective view of the cold air discharge duct from which the partition plate of the cold air discharge duct is removed.

3, the refrigerator 1 of this embodiment includes a main body 10, a freezing chamber 30 formed inside the main body 10 for freezing and storing food, a refrigerating chamber 30 provided on the right side of the freezing chamber 30, A door 21 and 23 for opening and closing the freezing compartment 30 and the refrigerating compartment 40 respectively and a refrigerating unit 30 installed in the freezing compartment 30 for discharging the cold air in various directions (①, ② and ③) And a discharge duct (60).

As shown in FIG. 4, a machine room 17 in which electrical components such as a compressor 5 are installed is provided at a rear lower portion of the main body 10. A cooling chamber 11 in which cool air is generated is located in the rear region of the main body 10 and the cooling chamber 11 is connected to the freezing chamber 30 by a separation wall 13 provided at the rear of the freezing chamber 30 Respectively. A cool air discharge port 13a and a cool air discharge port 13b for communicating the freezing chamber 30 and the cooling chamber 11 are formed at the upper and lower portions of the separation wall 13 respectively.

An evaporator 7 for generating cold air is provided in the cooling chamber 11 and a blowing fan 12 for blowing the cool air generated in the evaporator 7 to the freezing chamber 30 is provided on the evaporator 7 And is installed adjacent to the cold air discharge opening 13a. Therefore, the cooling air in the cooling chamber 11 is discharged to the freezing chamber 30 while passing through the cooling air discharge opening 13a by the blowing fan 12.

In the space of the freezer compartment 30 located below the cold air discharge opening 13a, a plurality of shelves 31 are installed in which food or food containers are placed. The shelf 31 is cooled by being supplied with cold air discharged to the cold air discharge opening 13a.

On the other hand, the cold air discharge duct 13a is provided with a cold air discharge duct 60 for smoothly guiding cold air discharge to the freezer compartment 30.

The cold air discharge duct 60 includes a housing 61 connected to the cold air discharge port 13a and a partition plate 63 for partitioning the inner space of the housing 61 into an upper space S1 and a lower space S2 And a plurality of discharge ports 70 formed in the housing 61 to communicate with the upper space S1 or the lower space S2 and discharging the cold air in different directions.

As shown in FIG. 5, the housing 61 may have a bucket shape having a side surface and a bottom surface portion and both side surfaces having an open top surface. One opened side of the housing 61 is coupled to the cold air discharge opening 13a and the opened upper side is coupled to the upper portion of the freezing chamber 30. [

5, a rib 65 is coupled to one side of the housing 61, and a pair of flanges 66 are provided on the upper surface of the housing 61 as shown in FIG. 6, A pair of bosses 67 may be formed.

The housing 61 may have a shape in which the cross-sectional area gradually decreases from the cold air discharge opening 13a toward the end. The shape of the housing 61 compensates for the phenomenon that the flow rate of the cold air decreases from the cold air discharge port 13a to the end, thereby keeping the flow rate of the cold air constant. Therefore, the cool air passing through the housing 61 can be moved to the end of the housing 61 and smoothly discharged.

The partition plate 63 divides the internal space of the housing 61 into an upper space S1 and a lower space S2. The upper portion of the partition plate 63 becomes the upper space S1 and the lower portion of the partition plate 63 becomes the lower space S2 based on the position where the housing 61 is installed on the upper portion of the freezing chamber 30. [

The partition plate 63 serves to guide the cool air introduced into the space inside the housing 61 partitioned by the upper space S1 and the lower space S2 and to increase the flow rate of cool air. This can be explained by the Bernoulli theorem, which speeds up the flow through narrow passages.

The discharge port 70 includes a first discharge port 71 formed to communicate with the lower space S2 and a second discharge port 73 formed on both side portions of the housing 61 so as to communicate with the upper space S1. And a third discharge port 75 formed at an end of the housing 61 to communicate with the upper space S1.

The first discharge port 71 is formed at the bottom of the housing 61 so that the cold air moving from the cold air discharge port 13a to the lower space S2 is first discharged to the lower portion of the freezer compartment 30 ). The cool air can be supplied to the inside of the freezing chamber 30 at a position away from the freezing chamber door 21 by the first discharge port 71. [

The second discharge port 73 is formed in the center area of both sides of the housing 61 so that the cold air moving to the upper space S1 is discharged in the left and right directions of the housing 61 to move downward direction). By the second outlet port 73, the cold air can spread to a wider central region of the freezer compartment 30. [

The third discharge ports 75 are formed in pairs at the ends of the housing 61 so that the cold air discharged without being discharged to the second discharge port 73 is discharged (the third direction). The chilled air can be sent to a position adjacent to the freezer compartment door (21) by the third outlet (75).

Here, the discharge port may be arranged close to the cold discharge port 13a formed in the freezing chamber 30 in the order of the first discharge port 71, the second discharge port 73, and the third discharge port 75. Therefore, the cold air can be uniformly discharged to the entire area of the freezer compartment 30 through the first discharge port 71, the second discharge port 73, and the third discharge port 75 as described above.

Therefore, since the cold air can be discharged in various directions by the cold air discharge duct 60 of the present invention, the cooling of the freezer chamber 30 can be efficiently performed, and the temperature distribution inside the freezer chamber 30 can be made uniform .

In addition, since the cooling air is supplied to the inner space of the freezing chamber 30, it is possible to uniformly improve the refrigerating performance of the food placed on the shelf or the drawer and to reduce the temperature difference between the upper and lower portions of the freezing chamber 30 .

Hereinafter, preferred embodiments of the present invention are described with reference to the drawings, but the scope of the present invention is not limited thereto.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventive concept as defined by the appended claims.
