The controller 50 may control the thawing fan 14 and the thawing heater 12 according to the temperature of the thawing chamber D after the thawing fan 14 and the thawing heater 12 are turned on.

When the temperature of the thawing chamber D reaches the freezing chamber set temperature Tf and the zero temperature set temperature Td set closer to 0 ° C among the 0 ° C, the temperature of the thawing chamber D reaches the set temperature. The thawing fan 14 and the thawing heater 12 can be controlled to hold (Td).

Here, the freezer compartment set temperature (Tf) is the desired set temperature of the freezer compartment (2), the user, etc. can set the freezer compartment set temperature (Tf) through the input unit 40, the control unit 50 is the freezer compartment (2) the freezer compartment The cooling apparatus 30 can be controlled to maintain the set temperature Tf. The freezer compartment set temperature Tf may be set among temperatures from minus 35 ° C to minus 16 ° C.

In addition, the set temperature (Td) is a thawing completion temperature, it is preferably set to a temperature at which the meat can be easily sliced without the meat juice that can be an example of the damage animals, from minus 5 ℃ to minus 3 ℃ It can be set among the temperatures up to. Damaged animals may come out of the juice from the destroyed cells during the maximum ice crystal generation during the thawing process. When the thawing is completed and maintained at the set temperature (Td) among the temperatures from minus 5 ° C to minus 3 ° C, The outflow of juice can be prevented and nutrient loss can be minimized. The set temperature may have an upper limit value and a lower limit value, and the controller 50 controls the thawing fan 14 and the thawing heater 12 so that the temperature of the thawing chamber D maintains the upper limit value of the set temperature and the lower limit value of the set temperature. Can be controlled. For example, when the set temperature is minus 3 ° C, it is possible that the upper limit of the set temperature is minus 2.5 ° C and the lower limit of the set temperature is set to minus 3.5 ° C, and the thawing fan 14 and the thawing heater 12 are thawed. The actual temperature can be controlled to maintain from minus 2.5 ° C to minus 3.5 ° C.

When the temperature of the thawing chamber D reaches the set temperature Td, the controller 50 may turn off the thawing heater 12 and the thawing fan 14. The controller 50 may turn off the thawing heater 12 and the thawing fan 14 when the temperature of the thawing chamber D reaches the upper limit of the set temperature Td, and then the temperature of the thawing chamber D is set. When the lower limit of the temperature Td is reached, the thawing heater 12 and the thawing fan 14 can be turned on, and then the thawing heater 12 and the thawing fan 14 are turned on in the thawing chamber D. ) On and off of the thawing heater 12 and the thawing fan 14 can be repeated as the upper limit is reached and the upper limit of the set temperature Td of the thawing chamber D temperature is reached.

The controller 50 reduces the input of the thawing heater 12 when the temperature of the thawing chamber D reaches the set temperature Td, and defrosts the chamber D when the temperature of the thawing chamber D maintains the set temperature Td. ) Can maintain the input of the thawing heater 12, which can maintain the set temperature Td. The controller 50 may adjust the current input to the thawing heater 12 and may apply the thawing set current to the thawing heater 12 until the temperature of the thawing chamber D reaches the set temperature Td. . The controller 50 may reduce the current input to the thawing heater 12 when the temperature of the thawing chamber D reaches the set temperature Td, and the temperature of the thawing chamber D maintains the set temperature Td. If it is, the current input to the thawing heater 12 can be maintained. When the temperature of the thawing chamber D reaches the upper limit of the set temperature Td, the controller 50 may reduce the input of the thawing heater 12 without turning off the thawing heater 12. It is possible to prevent a sudden drop in temperature of the thawing chamber D, which may be generated when the thawing heater 12 is turned off, and to prevent frequent on and off of the thawing heater 12. The controller 50 can linearly reduce the input of the thawing heater 12 and can reduce the input step by step. The controller 50 may decrease the input of the thawing heater 12 until the temperature of the thawing chamber D reaches the lower limit of the set temperature Td. When the temperature of the thawing chamber D reaches the lower limit of the set temperature Td, the controller 50 stops decreasing the input of the thawing heater 12 and the temperature of the thawing chamber D reaches the lower limit of the set temperature Td. The thawing heater 12 input can be maintained when reached. While the input reduction of the thawing heater 12 continues, the temperature of the thawing chamber D may maintain the set temperature Td for the set time Ts. That is, the temperature of the thawing chamber D may maintain the upper limit of the set temperature Td and the lower limit of the set temperature Td for a set time Ts after the input of the thawing heater 12 begins to decrease. 50 can hold the input of the thawing heater 12 when the set time Ts has elapsed. When the thawing heater 12 maintains the input as described above, the temperature of the thawing chamber D may maintain the upper limit of the set temperature Td and the lower limit of the set temperature Td.

 If the temperature of the thawing chamber (D) maintains the set temperature (Td), the control unit 50 can maintain the temperature of the thawing fan 14, it is possible to reduce the rotational speed of the thawing fan 14, It is possible to turn off the thawing fan 14. The thawing fan 14 may be turned on at the thawing set speed at the time of input of the thawing command, and then reduced or turned off at a rotation speed lower than the thawing set speed if the temperature of the thawing chamber D maintains the set temperature Td. It is possible. The thawing fan 14 may reduce power consumption when the rotational speed is reduced or turned off. When the control unit 50 reduces the rotational speed of the thawing fan 14, it is possible to reduce the rotational speed of the thawing fan 14, such as to decrease the input of the thawing heater 12, and the input of the thawing heater 12 is reduced. If maintained, it is possible to maintain the rotational speed of the blowing fan 14 as in the case of the thawing heater 12. The controller 50 may periodically turn on and off the thawing fan 14 after the thawing fan 14 is turned off when the thawing fan 14 is turned off. The air in the thawing chamber D can prevent the thawing chamber D from being cooled again by the cold air in the freezing chamber 2 while circulating the thawing heater 12 and the damaged animal while the thawing fan 14 is on. The power consumption can be reduced while the thawing fan 14 is off. The control unit 50 can continuously turn on the thawing fan 14 while the input reduction of the thawing heater 12 continues, and turning off the thawing fan 14 at the time when the input of the thawing heater 12 is maintained. The thawing fan 14 can then be turned on and off periodically.
