cool air supplier 310 includes a first through-hole 311 in the rear surface of the temperature changingroom 300, a second through-hole 312 in therear surface 170 of the inner case of thebody 100 of the refrigerator communicating with the first through-hole 311, and a coolair supplying fan 314 adapted to supply the cool air from theevaporator 110 to the second through-hole 312. - Especially, a
damper 313 is disposed in the first through-hole 311 or the second through-hole 312 to control an amount of cool air introduced thereinto, and in this case, the coolair supplying fan 314 is mounted between thedamper 313 and theevaporator 110. - The cool
air supplying fan 314 is simply coupled to the rear wall of thebody 100 of the refrigerator forming thecool air duct 102. - The first through-
hole 311 extends into the second through-hole 312 and is coupled to the inner peripheral surface of the second through-hole 312. Accordingly, if the temperature changingroom 300 and therear surface 170 of the inner case of thebody 100 of the refrigerator are coupled to each other, the first through-hole 311 can be rigidly coupled to the second through-hole 312, without any leakage of the cool air through them. - Further, a
temperature sensor 320 is mounted on the inside of the temperature changingroom 300, for example, on an inner wall surface thereof, to check the internal temperature of the temperature changingroom 300 in real time, and thetemperature sensor 320 is electrically connected to thedamper 313. - That is, the
temperature sensor 320 and thedamper 313 are electrically connected to each other, and therefore, the opening and closing angle of thedamper 313 can vary in accordance with the set temperature of the temperature changingroom 300. - For example, if the internal temperature of the temperature changing
room 300 is drastically raised, thedamper 313 completely opens to lower the internal temperature of the temperature changingroom 300, and contrarily, if the internal temperature of the temperature changingroom 300 is maintained at the set temperature or lower than the set temperature, thedamper 313 closes. - Accordingly, the
damper 313 has a well-known electrically operating configuration. - Further, the temperature changing
room 300 is in the lower portion of thebody 100 of the refrigerator, thereby sending cool air indirectly to a vegetable bin in the lower portion of thebody 100 of the refrigerator. - On the other hand, an
additional control damper 330 is mounted on thecool air duct 102 behind therear surface 170 of the inner case of thebody 100 of the refrigerator to control the supply of cool air generated by theevaporator 110 to the cold room or the freezer. - That is, the
control damper 330 is adapted to first supply the cool air from theevaporator 110 to the temperature changingroom 300, and after a given period of time passes, to supply the cool air to the freezer and the cold room of thebody 100 of the refrigerator. - In this case, the
control damper 330 is mounted on one side wall of thecool air duct 102 and has a hinge-operating structure that is capable of turning through electrical operation. - The
control damper 330 is mounted above theevaporator 110 and closes a part of the space in thecool air duct 102 in which theevaporator 110 is disposed when thecompressor 120 stops operating. - After the operation of the
compressor 120 stops, the part of the space in thecool air duct 102 including theevaporator 110 is closed, so that even if thecompressor 120 stops operating, the cool air needed in the temperature changingroom 300 is supplied using the cold air accumulated around theevaporator 110. - The temperature changing
room 300 according to the present invention is configured with thecool air supplier 310 that receives cool air directly from theevaporator 110 behind therear surface 170 of the inner case of thebody 100 of the refrigerator, thereby completely preventing the items stored in the temperature changingroom 300 from being contaminated with a peculiar smell from the freezer, and thereby allowing the cool air to rapidly lower the temperature of the temperature changingroom 300 to the set temperature. - Further, the
additional control damper 330 is mounted in thecool air duct 102 behind therear surface 170 of the inner case of thebody 100 of the refrigerator to control the supply of the cool air from theevaporator 110 to the cold room or the freezer, so that the cool air from theevaporator 110 is first supplied to thetemperature changing room 300 and then to the freezer and the cold room, and even if thecompressor 120 stops operating, the cool air needed in thetemperature changing room 300 can be supplied using the cold air accumulated around theevaporator 110. - While the present invention has been described with reference to particular illustrative embodiments, it is not to be restricted by the embodiments, but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
