The connection holes 243 are formed so as to be hinged by the first and second connection bolts 250 and 251 inserted into the through holes 42 from the outside of the special chamber 40 at the same time. .

In this case, the hinge hole 232 of the second operation member 230 and the connection hole 243 of the opening and closing member 240 are formed in the same polygonal shape (square), and the first and second connection bolts ( 250 and 251 are formed in a quadrangular shape corresponding to the hinge hole 232 and the connection hole 243.

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

When the refrigerator is operated in order to maintain the freezer compartment 20, the refrigerating compartment 30, and the specialty compartment 40 at a predetermined temperature for storing food, the high-temperature and high-pressure gas refrigerant is compressed by the compression action of the compressor 60. Discharged through the main condenser 70 and the sub condenser 100 to condense.

The gas refrigerant condensed while passing through the main condenser 70 is phase-reduced into a high-pressure liquid refrigerant at a temperature slightly higher than the room temperature, which is the ambient temperature of the refrigerator, and decompressed by passing through a capillary tube (not shown). As it is introduced into the evaporator 80 and expanded, it vaporizes at a low temperature and low pressure and simultaneously evaporates.

At this time, the cold air generated by the evaporation of the evaporator 80 is first stayed in the freezer compartment 20 and at the same time the cold compartment (30) through the cold air passage (L) formed between the special chamber 40 and the cabinet (10) By supplying to the various kinds of foods stored in the freezing chamber 20, the refrigerating chamber 30 and the specialty chamber 40 is frozen and refrigerated.

On the other hand, in order to adjust the amount of cold air supplied from the freezer compartment 20 to the refrigerating compartment 30 to be reduced (for example, about), first, the front end side of the first operating member 220 installed on one side of the specialty compartment 40. If the first operation member 220 is lowered while holding the center of the hinge bolt 210 hinged to the special chamber 40 through the center thereof, as shown by a dashed line in FIG. The front end side is pivoted down, and the rear end side is tilted up.

When the first operating member 220 is seesawed, the second operating member 230 passes through the rear end side and the special chamber 40 and is hinged to the opening / closing member 240. The front end side thereof is pivoted up.

The hinge shaft 231 protruding from the front end side of the second operating member 230 is inserted into the long hole 223 formed at the rear end side of the first operating member 220 of the first operating member 220. When the rear end side is moved up and down, the front end side of the second operating member 230 is guided up and down by moving the position from the front side to the rear side of the long hole 223.

When the front end side of the second operating member 230 is pivoted up, the first connecting bolt 250 hinged to the rear end side hinge hole 232 is rotated in one direction (for example, clockwise direction). When the first connection bolt 250 is rotated, the opening and closing member 240 hinged to the end thereof is rotated as shown by the dashed-dotted line of FIG. 5.

That is, the shaft portion (not shown) formed in the polygonal shape of the first connection bolt 250 is first inserted into the polygonal hinge hole 232 formed at the rear end of the second operating member 230 to protrude to the opposite side, and then selected It is inserted so as not to receive rotational interference through a circular through hole 42 formed at one end of one side of the seal 40 and protrudes into the special chamber 40, and also has a lower end of the side plate 242 of the opening / closing member 240. Since the structure is finally inserted into the polygonal connecting hole 243 formed in the first connecting bolt 250 is rotated at the same time when the second operating member 230 rotates the opening and closing member 240.

Therefore, the opening / closing member 240 narrows the cold air passage L by the upper end of the opening and closing member 240 approaching the inner wall of the cabinet 10 as the front end side of the first operating member 220 descends. Some of the cold air flowing from the freezer compartment 20 to the refrigerating compartment 30 forms a refrigeration cycle that is reduced and supplied to the refrigerating compartment 30 through the narrowed cold air passage L, and the other part of the body of the opening / closing member 240 ( 241 is sharply turned into the special chamber 40 to form a freezing cycle circulating in the freezing chamber 20.

At this time, when storing a large amount of frozen food in the freezer compartment 20, and a small amount of refrigerated food in the refrigerating compartment 30, unnecessary cold air is not supplied to the refrigerating compartment 30 by the narrowed cold passage (L). In addition, the operating time of the compressor 60 can be shortened, as well as the power consumption can be reduced.

Next, in order to adjust the amount of cold air supplied from the freezing chamber 20 to the refrigerating chamber 30 to increase (for example, steel), first, the front end of the first operating member 220 installed on one side of the special chamber 40. When the side is raised while holding the first operating member 220 is the second operating member hinged to the rear end while the seesaw movement, as shown by the solid line shown in FIG. 5 around the hinge bolt 210 by the reverse operation described above When the front end side of the 230 is rotated down, the second operating member 230 is rotated to the upper side of the opening and closing member 240 via the first connection bolt 250 when the lower rotation is rotated to the special chamber 40 side. As a result, the cold air passage L formed between the special chamber 40 and the cabinet 10 is widened.

In this case, since a large amount of cold air is supplied from the freezing chamber 20 to the refrigerating chamber 30 through the widened cold passage L, even if a large amount of the refrigerated food is stored in the refrigerating chamber 30, the proper temperature can be maintained within a short time. Will be.

As described above, according to the cold air flow control device of the direct-cooling refrigerator according to the present invention, since the cold air passage formed between the rear side of the special chamber and the inner wall of the cabinet can be variably controlled in multiple stages, the refrigerator compartment As it can eliminate the supply of cold air more than necessary, it is possible to shorten the operating time of the compressor and at the same time to minimize the power consumption.
