It is characterized by consisting of a bowl.

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

In the drawings, the same components as those in the related art are denoted by the same name and the same reference numerals, and detailed description thereof will be omitted.

The freezer compartment rapid ice making apparatus according to the present invention receives cold air discharged through the cold air discharge hole 61 of the first damper cover 60 so as not to be discharged to the door 34 as shown in FIG. Shelving means (300) provided at a position adjacent to the cold air discharge hole (61) so as to distribute evenly to the lower side of the freezing chamber (30) and to cool the inside quickly and uniformly, with a predetermined interval on the lower part of the shelf means (300) Ice crystal support 310 which is supported by the front and rear ends of the shelf means 300 and the sliding action so as to slide, and the entire water stored by the cold air ejection by quickly concentrated to the lower side by the shelf means 300 is ice crystals It consists of an ice bowl 320 seated on the upper surface of the ice bowl support 310 so as to be rapidly iced at the same time.

That is, the shelf means 300 is supplied with cold air discharged through the upper shelf 301 and the cold air discharge hole 61 is installed so that the storage container and the stored food (not shown) on the upper surface freezer chamber 30 The lower shelf 303 is tightly fixed to the rear end of the upper shelf 301 so as to be concentrated toward the lower side of the upper shelf 301 and forms a cold air flow passage 302 at a predetermined interval therebetween.

In this case, the lower shelf 303 is provided with a plurality of cold air distribution ports 303a at predetermined intervals in the front-rear direction thereof, and the cold air flow passage 302 of the cold air distribution port 303a is formed at an upper surface front end. The cold air guide piece 303b protrudes to be inclined so that the cold air flowing forward is hit and the flow is converted downward and guided to the cold air distribution port 303a.

Next, the operation and effects of the present invention configured as described above will be described.

As shown in FIG. 1, the main switch (not shown) is turned on in order to achieve a predetermined set temperature of the refrigerator, refrigeration, specialty and vegetable compartments 30, 31, 32, and 33 of the refrigerator. When the compressor (not shown) installed in the lower part of 10) is operated, the high-pressure and high-pressure gas refrigerant gas flows along the inside of the condenser (not shown) by the compression action of the compressor, thereby condensing.

Then, the gas refrigerant condensed while passing through the condenser is phase-changed into a high-pressure liquid refrigerant at a temperature slightly higher than the room temperature, which is the ambient temperature of the refrigerator, and depressurized by passing through a capillary tube (not shown). As it enters and expands, it evaporates to low temperature and low pressure and at the same time evaporates to cool.

On the other hand, when the blower means 50 is driven and driven, the air in the freezer, refrigeration, specialty and vegetable chambers 30, 31, 32 and 33 is shown in FIG. As described above, the air flows through the cold air inlets 20a, 21a, and 22a respectively formed in the first to third intermediate members 20, 21 and 22, and at the same time, the cold air outlet 20b of the first intermediate member 20. By passing through the evaporator 80 installed on the rear side of the freezing chamber 30 is exchanged with cold cold.

The cold air heat-exchanged through the evaporator 80 is discharged into the gap formed by the coupling of the duct member 40 and the first damper cover 60 by the blowing force by the operation of the blowing means 50. At the same time, it is discharged to the freezing chamber 30 through the cold air discharge hole 61 formed in the first damper cover (60).

At this time, a part of the cold air discharged to the cold air discharge hole 61 is formed in the rear side by the combination of the upper and lower shelves 301 and the lower shelves 303 of the shelf means 300 as shown in the arrow direction shown in FIG. As the cold air flow path 302 flows forward and hits the plurality of cold air guide pieces 303b, which are formed to be inclined at predetermined intervals on the upper surface of the lower shelf 303, the cold air flow angle is converted downward and at the same time. By ejecting through the plurality of cold air distribution ports 303a located in the plurality of cold air guide pieces 303b, it is possible to prevent cold air from being discharged to the door 34 side, as well as cold air when the door 34 is opened. The loss of cold air discharged to the gas can be prevented in advance.

In addition, the cold air sprayed downward through the plurality of cold air ejection openings 303a is seated on the upper surface of the ice bowl support 310 as shown in FIG. 3 and is located at the bottom of the shelf means 300. By rapidly concentrating on the ice bowl 320, the water evenly stored in the ice bowl 320 is rapidly defrosted at the same temperature, thereby reducing the ice making speed by about 40 to 80 minutes compared to the conventional method and at the same time reducing the operation rate of the compressor. By shortening the power consumption can be reduced by 2% to 3% than conventional.

On the other hand, another part of the cold air discharged downward from the gap formed by the coupling of the duct member 40 and the first damper cover 60 is the electron of the damper means 90 as shown in the arrow direction shown in FIG. Alternatively, the cold air supply is constantly controlled by a mechanical operation and is supplied through the gap between the second damper cover 70 and the cabinet 10, and is formed in the vertical direction at regular intervals to the second damper cover 70. Refrigeration, specialty and vegetable compartment 31 by repeating the refrigerating, evenly distributed and discharged through the plurality of cold air outlets 71, 72, 73 into the interior of the refrigeration, specialty and vegetable compartments 31, 32, 33 respectively. (32) and (33) are to be freshly refrigerated various kinds of food stored in each.

As described above, according to the rapid freezing device of the freezer compartment of the present invention, the cold air discharged to the cold air discharge hole of the first damper cover is flowed through the cold air flow path formed between the upper side and the lower side shelf, and the lower side shelf It is designed to be distributed evenly and evenly to the ice bowl through a plurality of cold air outlets formed at the same time, and to be spread evenly and evenly to the freezer compartment. Therefore, the cold air loss is discharged straight to the door side by changing the discharge angle of the cold air to the lower side of the freezer compartment. At the same time, cold air discharged in the downward direction is evenly distributed over the entire area of the ice bowl, which shortens the ice making time and shortens the operation rate of the compressor, thereby reducing power consumption.
