The present invention relates to a special compartment shelf of the refrigerator, and more particularly, to a cold air inlet formed on the rear wall surface of the special compartment shelf in which cold air is introduced from the cold air outlet of the refrigerating chamber duct.

In general, the refrigerator is configured to supply the cold air generated from the evaporator of the refrigeration cycle to the storage compartment to maintain the freshness of various foods for a long time.

As shown in FIG. 1, the refrigerator is a storage compartment having an open front in a cabinet 10 constituting an outer body, so that a freezer compartment 11 storing frozen foods and a refrigerating compartment 12 storing refrigerated foods are partitioned. Is formed, the door (11a, 12a) for opening and closing the freezing chamber 11 and the refrigerating chamber 12 is hinged to the front surface of the cabinet (10).

In the rear of the freezing chamber 11 is formed a separate cooling chamber 20 for generating cold air and supplying it to the freezing chamber 11 and the refrigerating chamber 12, wherein the evaporator 21, the freezing chamber 11 and A circulation fan 22 for introducing air from the refrigerating chamber 12 into the evaporator 21 and forcibly blowing the generated cold air into the freezing chamber 11 and the refrigerating chamber 12 is incorporated.

The freezing chamber duct 40 and the refrigerating chamber duct 41 in which the cold air discharge ports 40a and 41a are arranged to properly distribute and guide the cold air to the freezing chamber 11 and the refrigerating chamber 12 are formed in the freezing chamber 11 and the refrigerating chamber 12. It is built on the rear wall. The refrigerating chamber duct 41 has a cold air discharge port 41a arranged up and down in order to evenly supply cold air to the entire refrigerating chamber 12, and includes a rotary wing 41b. In the partition 30 partitioning the freezing compartment 11 and the refrigerating compartment 12, return ducts 30a and 30b are formed to guide the air sucked by the suction force of the circulation fan 22 to the evaporator 21.

On the other hand, in the freezing chamber 11 and the refrigerating chamber 12, shelves 50 and 51 are configured in the horizontal direction so as to accommodate and store food, respectively. Since the internal space of the refrigerator compartment 12 is larger than the freezer compartment 11, the shelf 51 is provided in multiple stages to store a plurality of refrigerated foods, and on the upper portion thereof, food to be stored colder than the refrigerator compartment 12 such as meat and sashimi, or cooking immediately. Specialty compartment shelf 60 for storing food to be made is installed in a drawer type.

The special chamber 60 is composed of a side portion, a bottom portion and a rear wall surface to form a storage space therein, and the front and the upper portion are open. A handle 65 is provided on the front portion of the special chamber 60, and a cold air inlet 64 is perforated on the rear wall thereof, corresponding to the cold air discharge port 41a provided at the upper portion of the refrigeration chamber duct 41. In addition, the guide portion 61 is formed to protrude in the lateral direction on both side portions of the special chamber 60, the rail 62 is configured so that the guide portion 61 is fitted into the side wall of the refrigerating chamber 12 to slide. The solid shelf 60 is drawn out in the front-rear direction, and the cold air inlet 64 and the cold air outlet 41a are correspondingly positioned at the maximum inlet.

In the refrigerator configured as described above, when the circulation fan 22 is operated, air in the freezing compartment 11 and the refrigerating compartment 12 flows into the evaporator 21 through the return ducts 30a and 30b, which passes through the evaporator 21. The air is continuously cooled to the freezing chamber 11 and the refrigerating chamber 12 through the cold air discharge ports 40a and 41a of the freezing chamber duct 40 and the refrigerating chamber duct 41. Cold air is discharged to the compartment by the rotated blade 41b. Accordingly, the foods stored in the freezer compartment 11 and the refrigerating compartment 12 are stored in the frozen and refrigerated state, respectively, and at the same time, the cold air discharge port 41a and the cold air formed on the refrigerating chamber duct 41 inside the special chamber shelf 60. The cold air is directly introduced through the inlet port 64 to maintain the cool state of the meat.

On the other hand, since fish and meat must be stored so as not to freeze, the interior of the special chamber 60 is set to be maintained at about 0-1 ° C.

However, a small gap is formed between the cold air inlet 64 formed on the rear wall surface of the conventional chamber 60 and the cold air discharge port 41a of the refrigerating chamber duct 41, so that the cold air discharged from the refrigerating chamber duct 41 Some cases arise out of the refrigerating chamber 12. As a result, the internal temperature of the special chamber 60 rises above the set temperature, thereby reducing the freshness of the stored food, as well as making it difficult to supply cold air, thereby generating noise. In some cases, cold air flows out to the ceiling surface of the refrigerating chamber 12, where freezing may occur.

The present invention is to solve this problem, the purpose of the present invention is that the special chamber shelf is provided as a drawer type on the upper side of the refrigerating chamber and the cold air inlet is formed on the rear wall of the cold chamber duct corresponding to the cold air outlet. By installing the anti-vibration rubber pipe to prevent gaps with the cold air discharge port, the cold air discharged from the cold air discharge port flows directly into the special chamber by the anti-vibration rubber pipe, so that no cold air inflow noise is generated and the inside of the special chamber is always at a constant temperature. It is to provide a special shelf of the refrigerator to be maintained.

The refrigerator to which the present invention is applied, as shown in these, is formed in the cabinet 100 forming the appearance of the freezer compartment 110 for storing the frozen food and the refrigerating chamber 120 for storing the refrigerated food, which is an intermediate partition ( It is provided so that it may be divided up and down by 300). The doors 111 and 121 are hinged to the front surface of the cabinet 100 in a rotatable manner to open and close them.

A cooling chamber 200 is formed at the rear of the freezing chamber 110 to provide an evaporator 210 for generating cold air, and a circulation fan 220 as a means for forcibly blowing the generated cold air. The freezing chamber duct 400 and the refrigerating chamber duct 410 having a plurality of cold air discharge ports 401 and 411 arranged up and down are respectively installed on the rear side walls of the freezing chamber 110 and the refrigerating chamber 120 to guide the supply of cold air. Rotating blade 412 is built in the duct 410, the cold air discharge port 411 is formed evenly from the top to the bottom to discharge the cold air to the compartment in the entire refrigerating chamber 120. And the air after the heat exchange action in the freezer compartment 110 and the refrigerating chamber 120 is introduced into the evaporator 210 to be cooled again, the intermediate partition 300 for the return of cold air to the freezer compartment return duct 310 and the refrigerating compartment return duct. 320 is formed in communication with the evaporator 210 installation site.

In the freezer compartment 110 and the refrigerating compartment 120, shelves 500 and 510 are installed in a horizontal direction to accommodate various stored foods. In the refrigerating chamber 120 having a relatively large internal space, a shelf 510 is provided as a kankan to store a plurality of refrigerated foods, and a special compartment shelf 600 and a vegetable box on the upper and lower portions thereof form a separate storage space. 700 is configured as a drawer type.

Specially selected shelf 600 is maintained at about 0-1 ℃ to prevent freezing of meat, fish, etc., and freshly stored so as not to smell the other food, which is the side and bottom and rear to form a storage space therein It is composed of walls, and the front and the top are open. Guide portions 610 are formed to protrude on both side portions of the special chamber shelf 600, and the rail 620 is formed on the upper side portions of the refrigerating chamber 120 so that the guide portions 610 are inserted into the slides. When pulling out the handle 650, the guide part 610 slides along the rail 620, and the special chamber shelf 600 is withdrawn. And the plate-shaped cover 630 which opens and closes the front of the special chamber shelf 600 is installed so that rotational movement is possible using the hinge shaft 631. To this end, the hinge shaft 631 protrudes on both upper ends of the cover 630 and is coupled to the side surface of the refrigerating chamber 120, and the cover 630 rotates up and down about the cover 630 to open and close the front of the special chamber shelf 600.

In addition, a pair of cold air inlets 640 are perforated to correspond to the cold air outlet 411 of the refrigerating chamber 410 so that cold air flows into the rear wall of the special chamber 600, which is a characteristic element of the present invention. The dustproof rubber pipe 660 is inserted into the cold air discharged from the cold air discharge port 411 through the dustproof rubber pipe 660 directly flows into the special chamber (600).

The anti-vibration rubber pipe 660 has a guide flow path 660a formed therein and is made of a rubber material so as to have elasticity. This is a coupling rib formed to be fitted into a fixing jaw 641 formed to protrude outwardly from the cold air inlet 640. The 661 is molded and coupled to the cold air inlet 640 through the protruding portion so as to protrude outward. Accordingly, when the special chamber (600) is pushed to the maximum, the tip of the anti-vibration rubber pipe 660 is in close contact with the outer surface of the refrigerating chamber 410 so as to surround the cold air discharge port 411, there is no gap is generated, discharged from here The cold air is guided into the special chamber (600) through the anti-vibration rubber pipe 660, and also the noise due to the entry and exit of the special chamber (600).

Next, the operation and effects of the refrigerator configured as described above will be described. First, when the circulation fan 220 is rotated, the cold air generated in the evaporator 210 to the freezing chamber 110 and the refrigerating chamber 120 through the cold air outlet 411 of the freezing chamber duct 400 and the refrigerating chamber duct 410. It is supplied to the compartment and heat exchanged while cooling the stored food. The heat-exchanged air is again re-cooled by being introduced into the evaporator 210 through the freezer compartment return duct 310 and the refrigerating compartment return duct 320, and then supplied to the freezer compartment 110 and the refrigerating compartment 120, thereby freezing compartment 110 and the refrigerating compartment. The food stored in 120 will be kept fresh for a long time.

On the other hand, the special selection shelf 600 is the cold air discharged from the cold air discharge port 411 of the refrigerating chamber 410 flows through the guide flow path 660a of the anti-vibration rubber pipe 660, so that the internal temperature is always 0 ~ 1 ℃ As a result, the stored foods such as fish and meat are kept fresh without being frozen. In order to take out or store food stored in the specially selected chamber shelf 600, by holding the handle 650 provided on the front part and pulling forward, the guide part 610 slides along the rail 620 and the upper side of the opening of the refrigerating compartment 120. It is exposed to the outside through, at the same time the cover 630 coupled to the hinge shaft 631 is lifted, the food storage and withdrawal is made through the open front and the upper portion of the special chamber (600). On the contrary, when the special thread lathe 600 is pushed in, the guide part 610 slides along the rail 620 to enter the inside, and the cover 630 is dropped by its own weight to close the front of the special lathe 600 again. .

At this time, when the specially selected chamber shelf 600 is pushed to the maximum, the tip of the anti-vibration rubber pipe 660 fitted into the cold air inlet 640 and fixed as described above, the cold air discharge port formed in the upper portion of the refrigeration chamber 410 ( By being in close contact with the 411, the cold air discharged from the gas is immediately introduced into the special chamber 600 without being discharged to the outside. Accordingly, the cool air is smoothly introduced, so that no cold air inflow noise is generated, and constant cold air is always supplied to the inside, and friction noise is caused by the damping force of the anti-vibration rubber pipe 660 itself when the special lathe 600 enters and exits. It does not occur.

As described in detail above, the refrigerator compartment of the refrigerator according to the present invention has a drawer type on the upper side of the refrigerating chamber, and a cold air inlet is formed on the rear wall of the refrigerator to correspond to the cold air outlet of the refrigerating chamber duct. The installation prevented the occurrence of gap with cold air outlet.

Accordingly, the cold air discharged from the cold air discharge outlet flows directly into the interior of the special selection chamber through the anti-vibration rubber pipe so that no cold air noise is generated, and the interior of the special selection shelf is always maintained at a constant temperature, thereby improving its reliability. Since the tip of the anti-vibration rubber pipe comes into contact with the refrigeration chamber duct first when the maximum entry of the solid lathe, the noise due to the entry of the special lathe does not occur.
