It's about structure.

In general, the parallel refrigerator is provided in a manner in which the freezing compartment 2 and the refrigerating compartment 3 are arranged side by side with respect to the central insulation wall 4, as shown in FIGS. 1A and 1B. The front doors of the freezing chamber 2 and the refrigerating chamber 3 are provided with a door 5. The freezing chamber (2) and the refrigerating chamber (3) is to create a cold air in the refrigerator by the operation of the refrigeration cycle to circulate it to freeze and refrigerated food.

The refrigerating cycle is composed of a high pressure portion in which the refrigerant gas is maintained at a high pressure and circulated, and a low pressure portion in which the refrigerant gas is maintained at a low pressure and circulated. The high pressure unit is a compressor for converting a low-temperature low-pressure gas refrigerant into a high-temperature high-pressure gas refrigerant, a condenser for converting the high-temperature and high-pressure gas refrigerant changed in the compressor into a room temperature high-pressure liquid refrigerant, and a liquid refrigerant at room temperature and high pressure through the condenser It consists of a dryer for dehumidifying.

In this refrigeration cycle, the evaporator 8A is a double cold air circulation path 7 and 8 partitioned by the rear shroud 6 at the rear side of the freezing chamber 2 and the cold air circulation path at the rear side of the shroud 6. 8) installed vertically to exchange heat in the circulating air into the cold, and the cold air is forced to circulate inside the air by driving the blower fan 8B installed on the upper side of the evaporator 8A and the blowing force thereof. have. In addition, the circulated freezer compartment and the freezer compartment cold air are sucked to the evaporator 8A side and heat exchanged again, and then discharged to the freezer compartment 2 and the refrigerating compartment 3 by driving the blower fan 8B to the freezer compartment 2 and The food in the refrigerator compartment 3 is to be frozen and refrigerated.

As a result, a freezer compartment upper suction port (2C) is formed at the lower side of the grill pan (9) and the shroud (6) of the freezer compartment (2) and the refrigerating compartment (3). The refrigerating chamber suction port 4A is formed so as to pass to the wood 6 back side cold air circulation path 9 side. In addition, in the refrigerating chamber 3 and the grill pan 9 of the freezing chamber 2, several discharge ports 3A and 9A are formed at a vertically spaced left and right pairs in a vertical direction to circulate heat exchange in the evaporator 8A. Air can be discharged to the freezing chamber 2 and the refrigerating chamber 3.

In the parallel refrigerator configured as described above, a blower fan 8B installed at an upper side of the cold air circulation path 8 behind the shroud 6 in the freezer compartment 2 is driven, and driven by the blower fan 8B. Cold air passing through the shroud 6 and passing through the cold air circulation passage 8 at the rear side of the shroud 6 and through the freezing chamber upper suction port 2C, and through the central insulating wall 4, the cold air at the rear side of the shroud 6 The freezer compartment and the refrigerating chamber air are sucked through the refrigerating chamber suction port 4A leading to the circulation path 8 side, and are introduced to the evaporator 8A vertically installed in the cold air circulation path 8.

The freezing and refrigerating chamber air introduced in this way is heat exchanged by the evaporator 8A, and then, in the refrigerating chamber discharge port 3A formed at the upper side of the refrigerating chamber 3 and the grill pan 9 of the freezing chamber 2, a pair of left and right vertical directions Through the freezer compartment discharge port (9A) is installed in the freezer compartment 2 and the refrigerating chamber (3) is to be performed repeatedly repeatedly.

Is introduced into the cold air circulation path 7 on the front side of the shroud 6 so as to discharge cold air into the freezing chamber 2 through a discharge port 9A formed in the grill pan 9. At this time, the heat-exchanged cold air is discharged to the upper vessel 2A and the lower vessel 2B through the discharge port 9A formed in the rear grill pan 9 of the upper vessel 2A and the lower vessel 2B.

By the way, in the suction structure of the conventional parallel refrigerator, the suction port 2C of the freezer compartment 2 is formed adjacent to the discharge port 9A of the lower container 2B, and is heat-exchanged while passing through the evaporator 8A. A part of the cooled air discharged through the discharge port 9A is sucked through the suction port 2C together with the surrounding air, so that the inside of the lower container 2B cannot maintain a proper cooling state. As a result, frozen foods such as ice cream mainly frozen inside the lower container 2B are melted, such that the performance and reliability of the device are deteriorated.

Accordingly, it is an object of the present invention to provide a suction structure of a parallel refrigerator in which the cold air heat exchanged in the evaporator can reach the lower container of the freezing chamber, so that the lower container can be properly cooled.

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

2a and 2b shows the internal structure of the parallel refrigerator according to an embodiment of the present invention, Figure 3 shows the suction structure of the present invention. As shown in these drawings, the refrigerator main body 10 has a freezing compartment 20 and a refrigerating compartment 30 side by side separated by a heat-insulating wall 40 of a medium sugar as usual, and the rear side of the freezer compartment 20 Dual cold air circulation passages 21 and 22 are formed at the front and rear sides of the shroud 25, respectively.

An evaporator 23 is installed in the vertical direction in the cold air circulation path 22 at the rear side of the shroud 25, and the upper side of the evaporator 23 is forced to circulate heat exchanged air into the inside while passing through the evaporator 23. Blowing fan 24 is provided.
