BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a refrigerator, and more particularly, to a refrigerator that improves a structure of a guide passage for guiding air from a refrigerator to an evaporator, thereby reducing an amount of an evaporator.

Generally, the refrigerator is used for forced convection of the cool air around the cooler by a fan, or by installing cool air in each of the freezer compartment and the refrigerating compartment, and directly cooling the food to be stored in a frozen and refrigerated state for a long time.

A general refrigerator having such a function is provided with a main body 10 partitioned into a freezing chamber 11 and a refrigerating chamber 12 by partition walls 20 as shown in FIG. An evaporator 13 is provided at the rear of the freezing chamber 11 and a blowing fan 14 is provided at an upper portion of the evaporator 13. A distribution channel 15 is formed so that cool air blown by the blowing fan 14 is distributed to the freezing chamber 11 and the refrigerating chamber 12 and flows. In order to guide the circulated air flowing into the freezing compartment 11 and the refrigerating compartment 12 and then guided to the evaporator 13, a guide formed by the freezing compartment guide passage 31 and the refrigerating compartment guide passage 32 A flow path 30 is formed.

As shown in FIG. 2, the guide passage 30 is provided with a refrigerating compartment guide passage 32 at the center thereof by a partition wall 30a made of styrofoam or the like, A freezing chamber guide passage 31 is formed.

The temperatures of the air entering the freezing compartment guide passage 31 and the refrigerating compartment guide passage 32 are about -17 ° C. and about -1 to 1 ° C., respectively, and the freezing compartment guide passage 31 and the refrigerating compartment guide passage 32 The temperature of each of the escaping air is about -18 deg. C and 3 to 5 deg. C, respectively, so that heat is also transferred between the freezing compartment guide passage 31 and the air in the refrigerating compartment guide passage 32 while passing through the guide passage 30. [

However, since the temperature of the air exiting the guide passage is higher than the temperature of the evaporator, when the air is introduced into the evaporator, the moisture condenses on the surface of the evaporator, thereby generating a gassing effect. Particularly, since the air escaping from the refrigerating chamber guiding flow path is the temperature of the image, the implanting amount further increases. Such a phenomenon causes a problem of not only acting as a resistance in the air flow but also lowering the efficiency of the freezing cycle.

Also, since the flow direction of the air escaping from the guide passage and the position of the evaporator are made perpendicular to each other, the flow of the air that rises in the vertical direction becomes difficult, and the air flows up against the wall surface, Lt; / RTI >

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a refrigerator which reduces the amount of the evaporator generated by moisture contained in the air.

It is still another object of the present invention to provide a refrigerator in which the air flowed out of the guide passage is guided by the evaporator to reduce the loss of airflow.

In order to achieve the above object, the present invention provides a refrigerator comprising: a freezer compartment defined by a partition wall; an evaporator for generating cold air; a freezer compartment guide duct for guiding cold air circulating in the freezer compartment to the evaporator; And a conduction member provided between the outlet side of the freezing compartment communication channel and the evaporator for allowing the air to flow out from the freezing compartment communication channel and the refrigerating compartment communication channel to pass between the freezing compartment communication channel and the evaporator, .

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

Since the refrigerator according to the present invention is the same as the conventional component except for the conductive member provided on the outlet side of the guide passage, the same components are denoted by the same names and reference numerals.

The refrigerator to which the present invention is applied is provided with a main body 10 partitioned into a freezing chamber 11 and a refrigerating chamber 12 by partition walls 20 as shown in FIG. An evaporator 13 for generating cold air is provided at the rear of the freezing chamber 11 and a blowing fan 14 for forcibly blowing the generated cold air is provided in the upper portion of the evaporator 13. A distribution channel 15 is formed so that the cool air blown by the blowing fan 14 can be distributed to the freezing chamber 11 and the refrigerating chamber 12 and flow therethrough.

In the partition wall 20, the circulation air flowing into the freezing chamber 11 and the refrigerating chamber 12 by the distribution channel 15 is guided to the evaporator 13 and returned to the evaporator 13 for heat exchange, Respectively.

The guide passage 30 is provided with a freezing compartment guide passage 31 through which cold air circulating in the freezing compartment 11 flows and a refrigerating compartment guide passage 32 through which cold air circulating in the refrigerating compartment 12 flows, As shown in FIG. 4, the freezing compartment guide passage 31 is located on both sides of the freezer compartment guide passage 32 with the freezing compartment guide passage 32 at the center.

On the other hand, a conductive member (40) is provided between the guide passage (30) and the evaporator (13). In other words, the conductive member 40 is provided at the outlet side where the air introduced from the freezing chamber 11 and the refrigerating chamber 12 is discharged toward the evaporator 13.

In the embodiment of the present invention, a plate-shaped conductive member 40 made of a metal having good thermal conductivity such as aluminum is used. This conductive member 40 is provided across the outlet side of the guide passage 30, So that the air can be contacted before it is introduced into the evaporator (13). In addition, at least one of the air flowing out of the guide passage (30) is bended so as to flow naturally into the evaporator (13).

When the refrigerator cycle is performed to generate cold air in the evaporator 13, the generated cold air is blown by the blowing fan 14 and is distributed to the freezer compartment 11 and the refrigerating compartment 12 through the distribution channel 15 It flows. The cold air flowing into the freezing chamber 11 and the refrigerating chamber 12 can be circulated while the freezing chamber 11 is kept in the ice temperature and the refrigerating chamber 12 is kept in the low temperature to store and store the frozen food and the refrigerated food. The air circulated in the freezing chamber 11 and the refrigerating chamber 12 flows into the guide channel 30 and returns to the evaporator 13. The circulation process is repeated again.

Meanwhile, the temperatures of the air flowing into the freezer compartment guide passage 31 and the refrigerating compartment guide passage 32 during the circulation process are approximately 3 to 5 ° C and -18 ° C, respectively. The temperature of the air exiting the freezing compartment guide passage 31 when the refrigerant passes through the guide passage 30 and the partition wall 30a is discharged through the guide passage 30 is approximately -16 DEG C and the refrigerating compartment guide passage 32 ) Is approximately -1 to 1 DEG C. Heat is exchanged while the air exiting at this temperature is brought into contact with the conductive member (40) provided across the outlet side of the guide passage (30).

At this time, the central portion of the conductive member 40, which is in contact with the air from the refrigerating compartment guide channel 32, is maintained at a temperature of about -1 to 1 캜 at the beginning, and the temperature of the conductive member 40, The temperature of the both end portions is maintained at approximately -16 to -17 占 폚. In this state, heat conduction is performed in the conductive member 40 made of a metal having good thermal conductivity, and the temperature of the conductive member 40 is -8 to -10 ° C. Since the air having a different temperature flows out from the freezing compartment guide passage 31 and the refrigerating compartment guide passage 32 toward the conductive member 40 having such a temperature, moisture contained in the air condenses on the conductive member 40 due to the temperature difference Lt; / RTI > This phenomenon can be more actively generated in the conductive member 40 in contact with the outlet side of the refrigerating compartment guide channel 32 through which air having a temperature higher than that of the conductive member 40 is discharged. In this way, before the air flown out of the guide channel 30 flows into the evaporator 13, moisture in the air is con- ducted on the conductive member 40 so that the amount of implantation is reduced in the evaporator 13, Is arranged vertically and the contact area with air is wide, and the effect is further increased.

In addition, since the conductive member 40 is bent to guide the air to the evaporator 13 without any difficulty, the path of the air can be efficiently formed.

In this way, heat generated in the conductive member melts due to the heat of the heater installed to remove the property of the evaporator or the heat of the heater installed in the drain of the dehydrated water, and the dehydrated water is easily discharged from the conductive member .

Although the conductive member is made of a metal such as aluminum as an example, the conductive member is not limited thereto and can be applied to the present invention using a conductive member having a good thermal conductivity even if it is not a metal.

As described in detail above, in the refrigerator according to the present invention, the conduction member bent at the outlet side of the guide passage leading to the evaporator is installed. Therefore, by using the temperature difference between the air and the conductive member escaping from the guide passage, moisture contained in the air is impregnated in the conductive member, the amount of impregnation of the evaporator is reduced, and the airflow passing through the evaporator is smooth , And the refrigeration cycle can be efficiently performed. Further, there is an advantage that the air that has passed through the guide passage in the shape of the bent conductive member is guided by the evaporator without fail, and the defrost water according to the property of the conductive member can be easily removed.
