Description

Suction structure of parallel refrigerator

The present invention relates to a suction structure of a parallel refrigerator, and more particularly, to a suction structure of a pathological refrigerator capable of suppressing a decrease in freezing efficiency due to overcooling of the refrigerating chamber and a reduction in the flow path width.

In general, the parallel refrigerator is provided in such a way that the freezer compartment 2 and the freezer compartment 2 are arranged side by side with respect to the central heat insulation wall 4 as shown in FIGS. 1A and 1B to form the main body 1. The front doors of the freezing chamber 2 and the freezing chamber 2 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 enable the freezing and refrigeration of food.

The refrigeration cycle is composed of a high pressure section where the refrigerant gas is maintained at a high pressure and circulated, and a low pressure section where the refrigerant gas is maintained at a low pressure and circulated. The high pressure section includes a compressor for converting low-temperature low-pressure gas refrigerant into a high-temperature high-pressure gas refrigerant, a condenser for converting the high-temperature, high-pressure gas refrigerant changed by the compressor into a liquid refrigerant of room temperature and high pressure, and a liquid refrigerant at room temperature and high pressure through the condenser. It consists of a dryer for dehumidifying. And a capillary tube for converting the liquid refrigerant of room temperature and high pressure dehumidified through the low pressure unit into a liquid refrigerant of low temperature and low pressure, a capillary tube for changing the low temperature and low pressure liquid refrigerant changed in the capillary into a gas state, and a low temperature and low pressure liquid changed in the capillary tube. It consists of an evaporator which absorbs the external heat while changing the refrigerant into a gaseous state, and an accumulator that blocks the vaporized liquid refrigerant from entering the compressor.

In such a refrigeration cycle, the evaporator 7 is installed perpendicular to the cold air circulation path 6 on the rear wall side of the freezing chamber 2 so as to heat-exchange the air in the refrigerator to cold, and the cold air is the upper side of the zigsaw 97. The inside of the refrigerator is forcedly circulated by the blowing fan 8 installed in the chamber. The sun-refrigerated freezer compartment and the refrigerating compartment cold air are sucked to the evaporator 7 side and exchanged with heat, and then discharged to the freezer compartment 2 and the refrigerating compartment 3 by driving the blower fan 8 to the freezer compartment 2 and the refrigerating compartment. (3) The food inside can be frozen and refrigerated.

To this end, a freezing suction inlet 9A and a refrigeration suction inlet 9B are formed at the lower side of the shroud 9 of the freezing compartment 2 and the refrigerating compartment 3, respectively, and the freezing suction inlet 9A and the refrigeration suction inlet 9B are provided at an upper side thereof. The refrigeration discharge port 9C and the refrigeration discharge port 9D are respectively formed so as to discharge the circulating air sucked through the heat exchanger and exchanged by the evaporator 97 to the freezing chamber 92 and the refrigerating chamber 3, respectively.

On the other hand, the center heat insulating wall (4) is provided with a guide tube (9E) so that the air of the refrigerating chamber sucked through the refrigerating chamber suction port (9B) can flow into the freezing chamber (2) rear wall side cold air circulation path (6).

By this configuration, first, when the blowing fan 8 provided in the upper region of the cold air cooler channel 6 rotates, the air inside the freezing chamber 2 and the refrigerating chamber 3 is freezing inlet 9A and the cold intake port. Inflow is through 9B. The air in the refrigerating compartment 3 introduced through the refrigeration suction opening 9B is introduced into the cold air circulation path 6 through the guide tube 9E and installed vertically in the cold air circulation path 6 together with the air introduced through the refrigeration suction opening 9A. Heat is exchanged and cooled while passing through the evaporator (7). The heat-exchanged air is again discharged to the freezing chamber 2 and the refrigerating chamber 3 through discharge ports 9C and 9D formed at the upper side of the shroud 9 of the freezing chamber 2 and the refrigerating chamber 3. The discharged air cools the interior of the freezing compartment 2 and the refrigerating compartment 3 while repeatedly performing this process.

By the way, in the conventional parallel refrigerator, the guide tube 9E is provided so that the air of the refrigerating chamber 3 may flow into the cold air circulation path 6, which impairs workability. In addition, when the cold air circulation path 6 and the refrigerating chamber 3 communicate with each other by the guide pipe 9E, and the driving of the blower fan 8 is stopped, the air in the cold air circulation path 6 is evaporated by the evaporator 8. As it descends while passing through, the moisture in the air of the refrigerating chamber 3 is condensed inside the guide tube 9E, thereby reducing the flow path width, thereby impairing the overall refrigeration efficiency.

Accordingly, it is an object of the present invention to provide a suction structure of a parallel refrigerator that can suppress a decrease in freezing efficiency due to overcooling of the refrigerating compartment and a reduction in the flow path width.

In addition, it is preferable that the suction induction panel is integrally formed at the lower end of the grill pan so as to be inclined toward the front side with respect to the front-rear direction of the main body so as to guide the freezing chamber air to the freezing suction opening side formed in the shroud.

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

2A and 2B are views illustrating an internal structure of a parallel refrigerator according to an embodiment of the present invention, and FIG. 3 is a perspective view showing a suction structure of the present invention. As shown in these figures, the refrigerator main body 10 is divided into a freezing compartment 20 and a refrigerating compartment 30 side by side by a heat insulating wall 40 in the center. In the rear region of the freezing chamber 20, as illustrated in FIG. 2B, the front cold air circulation path 21 and the rear cold air circulation path 22 are formed around the shroud 25, respectively. An evaporator 23 is vertically installed in the rear cold air circulation path 22 so as to cool the air, and a blower fan 24 is installed above the evaporator 23 to promote the flow of air.

The front side cold air circulation path 21 is blocked by the grill pan 26, and the grill pan 26 has a plurality of discharge ports 26B formed at a vertically spaced left and right pair. The air in the freezer compartment 20 and the air in the refrigerating compartment 30 are sucked to the rear side cold air circulation passage 22 in which the evaporator 23 is installed in the cold air circulation passages 21 and 22 at the lower side of each cold air circulation passage 21 and 22. It is provided with a suction means for making.

As shown in FIG. 3, the suction means includes a refrigerating suction port 50 formed to suck the refrigerating chamber air toward the front side cold air circulation path 21 and a refrigerating chamber 20 from the refrigerating suction port 50. A blocking wall 51 extending toward the side, a plurality of cold air suction holes 52 formed in the blocking wall 51, a freezing suction port 53 formed below the cold air suction hole 52, and a freezing suction hole ( 53, the suction induction panel 26A formed at the lower portion of the grill pan 26 to guide the air of the refrigerating chamber 20 is configured.

The refrigerating suction opening 50 is formed to have a quadrangular shape having a confirmed width compared to a conventional connecting pipe. A barrier wall 51 is integrally formed in the shroud 25 so as to protrude from the hole of the refrigeration suction opening 50 toward the center side of the front side cold air circulation path 21. The blocking wall 51 is formed to be inclined downward in the form of a saga box having a front side and one side thereof, and is formed on the rear wall shroud 25 of the inner space formed by being blocked by the blocking wall 51. A plurality of cold air suction holes 52 are formed to allow the refrigerating chamber air sucked through the air to flow into the rear side of the cold air circulation path 22 of the shroud 25.

Here, the cold air suction hole 52 has a size relatively smaller than that of the refrigeration suction opening 50, and the air cooled by the evaporator 23 is stopped through the refrigeration suction opening 50 when the blowing fan 24 is stopped. It is formed in the lower side of the refrigeration suction port 50 to be introduced into the refrigerating chamber 30 to prevent the refrigerating chamber 30 from being overcooled.

In addition, a freezing suction opening 53 is formed at the lower side of the blocking wall 51 to allow the freezing chamber air to be sucked into the cold air circulation path 22 at the rear side of the shroud 25 through the lower side of the grill pan 26. The freezing suction opening 53 is formed over the entire width of the shroud 25, and a suction induction panel 26A is formed at a lower end of the green pen 26 to guide the freezing chamber air toward the freezing suction opening 53. It protrudes inclined downward toward the front side.

The upper wall of the freezing suction port 53 is a heat exchanger passing through the evaporator 23, the separation wall for blocking between the air introduced into the front side cold air circulation path 21 and the freezing chamber air sucked into the freezing suction port 53 side ( 54 is formed, and the grill pan 26 is provided with a discharge port 26B for discharging the heat exchange air introduced into the upper side of the separation wall 54 to the freezing chamber 20.

By this configuration, first, when the blower fan 24 installed on the upper side of the evaporator 23 is driven while the operation by the refrigeration cycle is started, the air in the freezer compartment 20 is the suction side induction panel of the lower side of the grill pan 26. It is guided to the freezing suction port 53 side formed in the lower side of the shroud 25 by 26A, and flows into the rear side cold air sneaker 22 through the freezing suction port 53.

The air of the refrigerating chamber 30 is sucked into the blocking wall 51 through the refrigeration suction opening 50 formed in the insulating wall 40, and the air sucked into the blocking wall 51 penetrates the shroud 25. It is introduced into the rear cold air circulation path 22 through the cold air suction hole 52. At this time, the blocking wall 51 and the separating wall 54 pass through the air introduced through the refrigeration suction opening 50, the air in the freezing chamber 20, and the front side cold air circulation path 21 cooled while passing through the evaporator 23. It will block each contact with air.

The air introduced into the rear cold air circulation path 22 through the freezing suction port 53 and the refrigeration suction port 50 is mixed with each other and flows to the upper area along the rear cold air circulation path 22 and installed in the upper region. It cools while passing through the evaporator 23. The air cooled while passing through the evaporator 23 is discharged to the freezing chamber 20 and the refrigerating chamber 30 through discharge ports 26B respectively formed in the grill pan 26 of the freezing chamber 20 and the refrigerating chamber 30.

On the other hand, when the driving of the blower fan 24 is stopped, air around the evaporator 23 cooled by performing a cooling action flows downward by convection, and the air flowed downward is a cold air suction hole 52.

At this time, the blocking wall 51 is formed to be inclined downward from the refrigerating suction opening 50 to the freezing chamber 20 side, the cold air suction hole 52 is formed below the refrigerating suction opening 50, the cold air suction opening 52 Since the air introduced into the blocking wall 51 is greater than the hot air of the refrigerating chamber 30, the air does not flow into the refrigerating chamber 30, and thus stays inside the blocking wall 51.

As described above, according to the present invention, by installing a shroud between the grill pan of the freezer compartment and the rear wall of the main body, the cold air circulation path is partitioned into the front cold air circulation path and the rear cold air circulation path, respectively, and the air from the cold compartment in the shroud. By integrally forming the blocking wall and the cold air suction hole that can be introduced into the rear cold air circulation path, there is no need to provide a separate guide tube unlike the prior art.

In addition, the barrier wall is formed to be inclined from the refrigerating suction inlet formed in the insulating wall to the freezer compartment, so that even when the blower fan is stopped, cold air from the evaporator flows into the refrigerating compartment and there is no fear of overcooling of the refrigerating compartment. Freezing occurs inside the tube to reduce the flow path width and thereby prevent the refrigeration efficiency from being impaired.
