Abstract

The present invention relates to a cold air flow control type cold air circulation structure of the refrigerator, and in particular, to install a separate blower fan on both sides of the evaporator is installed in the ceiling of the freezer compartment of the refrigerator at the same time, the refrigeration, refrigeration air flow inflow on the inner side wall of the refrigerator The airflow outlets of the freezing and refrigerating compartments are inclined downward in a state in which the airflow outlets of the freezing and refrigerating compartment are inclined downward, and are inclined downward to the front side where the doors of the refrigerating and refrigerating compartment are located. As a result of the formation of a plurality of chambers, temperature deviations in the front, rear, left and right areas of the inside of the refrigerator can be effectively excluded, and a plurality of sides of one side of the separation frame forming the freezing compartment and the refrigerating compartment, namely, one side of the door hinge part of the freezing and refrigerating compartment, are formed. Three 3-stage switches are installed so that the blower fan on the open side of the door depends on the opening / closing angle of the freezer and refrigerator compartment. Or air blowers formed by the airflow at the front of the freezing and refrigerating chambers while the blowing fan at the door opening side and the blowing fan at the door hinge side are simultaneously driven so as to effectively prevent the discharge of air flow at the time of opening and closing the door. Therefore, it is possible to expect the effect of minimizing the operation rate of the refrigerator and increasing the cooling efficiency of the cooling device.

Claims (7)

In a conventional refrigerator in which a freezer compartment (1) and a refrigerating compartment (2) are partitioned through a separation frame (11), and the evaporator (12) is built up above the freezer compartment (1), a blower fan for air circulation on both sides of the evaporator (12). While installing (13, 14) and forming an air flow circulation passage communicating with the freezer compartment and the refrigerating compartment inside both side walls of the refrigerator below the refrigerator, a plurality of switches (21, 22) on one side of the door hinge of the separation frame (11) By arranging), the operation of opening and closing the doors of the freezer compartment 1 and the refrigerating compartment 2 is performed to selectively drive the blower fans 13 and 14 so that air curtains are formed on the front side of the freezer and refrigerator compartment by airflow. Cold air flow control controlled cold air circulation structure of the refrigerator, characterized in that configured. The airflow circulation path located directly below the blower fan (13, 14) is provided with a diaphragm (15) from the top of the center to the lower portion of the freezer compartment (1), the freezer compartment airflow passage (16) and the refrigerator compartment airflow inlet While allowing the furnace 17 to be isolated, a plurality of air flow outlets 16 'and 17' communicating with each freezing and refrigerating compartment are formed at appropriate intervals before and after the freezing and refrigerating compartment, and communicating with the evaporator 12 side. The air flow suction inlets 19 and 20 are formed in the upper central portion of the freezer compartment 1 and the refrigerating compartment 2, characterized in that the cold air flow release control type cold air circulation structure of the refrigerator. The cold air flow control type of the refrigerator according to claim 1 or 2, wherein the airflow outlets (16 ', 17') communicating with the freezing and refrigerating compartment are inclined downward at an appropriate angle. According to claim 1 or 2, characterized in that the upper end of the refrigerating compartment airflow inlet path 17 is formed in the airflow circulation path by installing an airflow control duct (18) that is controlled to open and close controlled by the refrigerator compartment temperature sensor. Cold air flow control structure of the refrigerator. The cold air flow control type cold air circulation of the refrigerator according to claim 1, characterized in that the switch (21, 22) for selectively driving the blower fan (13, 14) during the door opening and closing operation is constituted by a three-stage switch operated in three stages. rescue. According to claim 1 or 5, wherein the three-stage switch is to be switched to the ON state in the first stage of the door is completely closed, the second stage of opening the door within a set angle and the third stage of opening the door over a set angle, In the second stage, only the blower fan 13 positioned at the door opening side is driven, and in the third stage, the two blower fans 13 and 14 are simultaneously driven. . 7. The cold air flow control structure of a refrigerator according to claim 6, wherein the door opening angle for dividing the second and third stages of the three-stage switch is set to about 70 degrees. ※ Note: The disclosure is based on the initial application.
