The refrigerator according to the present invention includes a quenching chamber 60 at the lower end of the freezing chamber 30 front side of the intermediate space 50 separating and partitioning the freezing chamber 30 and the refrigerating chamber 40.

The quenching chamber 60 is formed by embedding a quenching chamber case 61 at an intermediate space, and the quenching chamber case 61 is formed in a "U" shape so that the to-be-cooled objects such as cans and bottles are sufficiently contacted. Buried, the quench chamber cover 62 covers the upper portion of the quench chamber case 61. In addition, the upper side of the quench chamber cover 62 is provided with a quench chamber door 63 so that the object to be cooled (a) can be put into or removed from the quench chamber case 61 and the freezer compartment 30 is shielded from the cold air. .

In addition, left and right sides of the quenching chamber case 61 are provided with a quenching chamber cold inlet 64 through which cold cold air of the freezing chamber 30 is introduced and a quenching chamber cold air outlet 65 through which the sucked cold air is discharged into the freezing chamber 30. do. In addition, a quenching chamber fan 68 for forcibly discharging cold air into the freezing chamber 30 is installed at the lower end of the quenching chamber air discharge outlet 65, and is electrically connected to the controller to be controlled by the controller.

On the other hand, one side of the quenching chamber case 61 is in close contact with the quenching chamber case 61 is installed a quenching chamber temperature sensor 67 for detecting the temperature of the quenching chamber 60. In addition, after the cooled object (a) stored in the quenching chamber (60) is cooled, a storage heater (66) that generates heat so that the cooled object (a) is not cooled more than necessary by the transfer of cold air from the freezing chamber (30). ) Is installed to surround the outer wall of the quenching chamber case 61 and is connected to the control unit 80 to be controlled by the control unit 80.

In addition, a quench key for quench input of the object to be cooled (a) stored in the quenching chamber 60 and a key input unit 10 having a display unit are connected to the control unit 80. The display unit is a light emitting diode (LED) or the like. Implementation is possible. In addition, the freezer compartment temperature sensor 34 for sensing the temperature of the freezer compartment 30, the refrigerator compartment temperature sensor 44 for detecting the temperature of the refrigerating compartment 40, and the outside air temperature sensor 20 for sensing the temperature outside the refrigerator control unit It is connected to 80.

Looking at the operation by the above-described component is as follows.

The user opens the quench chamber door 63 and puts it in the quench chamber 60 to select the quench chamber operation key through the key input unit 10 for rapid cooling. . The control unit 80 determines whether there is a quenching chamber key input (S10). The key input unit 10 outputs the quenching chamber key input signal when the user inputs the quenching chamber operation key, and the control unit 80 inputs the quenching chamber key. Recognize.

After the controller 80 recognizes the quenching chamber key input, the control unit 80 outputs a control signal to the key input unit 10 to display the quenching chamber operation S20 on the display unit, and detects the quenching chamber by the quenching chamber temperature sensor 67. The temperature of 60 is determined. The controller 80 determines whether the temperature of the quenching chamber 60 determined by the quenching chamber temperature sensor 67 is higher than a preset temperature (S30).

If the temperature of the quenching chamber 60 determined by the quenching chamber temperature sensor 67 is higher than the preset temperature, the controller 80 operates the quenching chamber fan 68 (S31). When the quenching chamber fan 68 is operated, cold air of the freezing compartment 30 is sucked through the quenching chamber air intake port 64 and flows into the quenching chamber 60. The cold air introduced into the quenching chamber 60 cools the object to be stored in the quenching chamber 60 and is discharged to the freezing chamber 30 through the quench chamber cooling air outlet 65 by the quenching chamber fan 68. do.

However, if the temperature detected by the quenching chamber temperature sensor 67 is not higher than the preset temperature in the determination S30, the controller 80 determines the temperature of the quenching chamber 60 through the quenching chamber temperature sensor 67. The controller 80 determines whether the temperature sensed by the quenching chamber temperature sensor 67 is lower than the preset temperature (S40).

If the temperature of the quenching chamber 60 is lower than the preset temperature, the controller 80 stops the operation of the quenching chamber fan 68 (S41).

After the controller 80 stops the quench chamber fan 68, the controller 80 drives the storage heater 66 (S42). Accordingly, the storage heater 66 generates heat to heat the quenching chamber 60.

However, if the temperature sensed by the quench chamber temperature sensor 67 is not lower than the preset temperature in the determination S40, that is, the temperature of the quench chamber 60 determined by the quench chamber temperature sensor 67 is preset. If higher, the control unit 80 stops the operation of the storage heater 66 (S50), and drives the quenching chamber fan 68 (S60).

Accordingly, the cold air of the freezer compartment 30 is introduced into the quench chamber 60 through the quench chamber air inlet 64 to cool the object to be cooled and discharged to the freezer compartment 30 through the quench chamber air outlet 65. do.

Thus, the temperature of the quenching chamber 60 can be maintained at a preset temperature. The preset temperature here is the temperature at which the beverage does not freeze.

By the rapid cooling chamber of the refrigerator according to the present invention, the object to be cooled is stored in a quenching chamber made of a quenching chamber case, and when the temperature detected by the quenching chamber temperature sensor is higher than a preset temperature, the quenching chamber fan is driven to Cool air is circulated to the quenching chamber, and if the temperature detected by the quenching chamber temperature sensor is lower than the preset temperature, the quenching chamber fan is stopped and the preservation heater is driven to quickly cool the object to be cooled by the cold air in the freezer compartment. In addition, it is possible to maintain the temperature of the quenching chamber at a preset temperature, thereby preventing the frozen object stored in the quenching chamber from being frozen and broken.
