Refrigerator Having Frozen Food Thawing Function

Abstract

The present invention relates to a refrigerator ( 1 ) comprising a fresh food compartment ( 2 ) wherein objects to be cooled are placed, a freezing compartment ( 3 ) wherein objects to be frozen are placed and a thawing compartment ( 4 ) disposed inside the fresh food compartment ( 2 ), wherein the frozen objects are placed.

1 . A refrigerator ( 1 ) comprising a fresh food compartment ( 2 ) wherein objects to be cooled are placed, a freezing compartment ( 3 ) wherein objects to be frozen are placed and a thawing compartment ( 4 ) disposed inside the fresh food compartment ( 2 ), wherein the frozen objects are placed, a heater ( 5 ) providing the interior of the thawing compartment ( 4 ) to be heated, a sensor ( 8 ) that detects the temperature inside the thawing compartment ( 4 ) and a control unit ( 6 ) that detects the operation time (t h ) elapsing for reaching the upper limit temperature value (T upper ) predetermined by the producer and recorded in its memory and that operates the heater ( 5 ) by applying consecutive operation times (t h ) and stopping times (t off ),
 characterized by the control unit ( 6 ) that   compares the last detected operation time (t h ) with the previous operation time (t h-1 ) and   continues the thawing process or stops the thawing process according to the result of the comparison.   
     
     
         2 . A refrigerator ( 1 ) as in  claim 1 , characterized by the control unit ( 6 ) that compares the ratio (R=t h /t h-1 ) of the last detected operation time (t h ), to the previous operation time (t h-1 ) with a limit ratio (R limit ) recorded in its memory, predetermined by the producer and ends the thawing process if the last detected ratio (R) is smaller than the limit ratio (R limit ) value. 
     
     
         3 . A refrigerator ( 1 ) as in  claim 1 , characterized by the thawing compartment ( 4 ) having at least one fan ( 7 ) providing the air therein to be propelled and the control unit ( 6 ) providing the thawing process to be ended by stopping the fan ( 7 ) if the last detected ratio (R) is smaller than the limit ratio (R limit ) value. 
     
     
         4 . A refrigerator ( 1 ) as in  claim 3 , characterized by the control unit ( 6 ) that ends the thawing process if the last detected ratio (R) is smaller than 0.5. 
     
     
         5 . A refrigerator ( 1 ) as in  claim 3 , characterized by the control unit ( 6 ) that ends the thawing process if the last detected ratio (R) is equal to 0.5. 
     
     
         6 . A refrigerator ( 1 ) as in  claim 1 , characterized by the control unit ( 6 ) that compares the difference (D=t h −t h-1 ) between the last detected operation time (t h ) and the previous operation time (t h-1 ) with a limit value (D limit ) recorded in its memory, predetermined by the producer and ends the thawing process if the last detected difference (D) is greater than the limit value (D limit ). 
     
     
         7 . A refrigerator ( 1 ) as in  claim 6 , characterized by at least one button ( 10 ) that provides the thawing process to be started or ended by being actuated by the user. 
     
     
         8 . A refrigerator ( 1 ) as in  claim 7 , characterized by at least one alerter ( 9 ) that enables the user to be informed when the thawing process is started or ended. 
     
     
         9 . A refrigerator ( 1 ) as in  claim 1 , characterized by the thawing compartment ( 4 ) having at least one fan ( 7 ) providing the air therein to be propelled and the control unit ( 6 ) providing the thawing process to be ended by stopping the fan ( 7 ) if the last detected ratio (R) is smaller than the limit ratio (R limit ) value. 
     
     
         10 . A refrigerator ( 1 ) as in  claim 1 , characterized by the control unit ( 6 ) that ends the thawing process if the last detected ratio (R) is smaller than 0.5. 
     
     
         11 . A refrigerator ( 1 ) as in  claim 1 , characterized by the control unit ( 6 ) that ends the thawing process if the last detected ratio (R) is equal to 0.5. 
     
     
         12 . A refrigerator ( 1 ) as in  claim 1 , characterized by at least one button ( 10 ) that provides the thawing process to be started or ended by being actuated by the user. 
     
     
         13 . A refrigerator ( 1 ) as in  claim 1 , characterized by at least one alerter ( 9 ) that enables the user to be informed when the thawing process is started or ended. 
     
     
         14 . A refrigerator ( 1 ) as in  claim 4 , characterized by at least one button ( 10 ) that provides the thawing process to be started or ended by being actuated by the user. 
     
     
         15 . A refrigerator ( 1 ) as in  claim 14 , characterized by at least one alerter ( 9 ) that enables the user to be informed when the thawing process is started or ended.
