Refrigerator and /or freezer

Abstract

The present invention relates to a refrigerator and/or freezer with a magnetic cooler, comprising a cold heat exchanger for cooling the cooling and/or freezing space of the appliance and means for detecting a value representative of the temperature of the cold heat exchanger, wherein the appliance includes a control or adjusting unit by means of which the temperature and/or the amount of the heat transfer medium supplied to the cold heat exchanger is adjustable such that in cooling operation the temperature of the cold heat exchanger does not go below 0° C.

1 . A refrigerator and/or freezer with a magnetic cooler, comprising a cold heat exchanger for cooling the cooling and/or freezing space of the appliance and means for detecting a value representative of the temperature of the cold heat exchanger, wherein the appliance includes a control or adjusting unit by which the temperature and/or the amount of the heat transfer medium supplied to the cold heat exchanger is adjustable such that in cooling operation the temperature of the cold heat exchanger does not go below 0° C. 
   
   
       2 . The refrigerator and/or freezer according to  claim 1 , wherein the appliance includes a pump for delivering the heat transfer medium and that the control or adjusting unit is configured such that it varies the delivery volume of the pump. 
   
   
       3 . The refrigerator and/or freezer according to  claim 1 , wherein the control or adjusting unit is configured such that it varies the strength or position of the magnetic field acting in the magnetic cooler. 
   
   
       4 . The refrigerator and/or freezer according to  claim 1 , wherein the control or adjusting unit is configured such that the temperature of the cold heat exchanger is adjusted to a specified desired value or within a range of desired values. 
   
   
       5 . The refrigerator and/or freezer according to  claim 1 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation. 
   
   
       6 . The refrigerator and/or freezer according to  claim 2 , wherein the control or adjusting unit is configured such that it varies the strength or position of the magnetic field acting in the magnetic cooler. 
   
   
       7 . The refrigerator and/or freezer according to  claim 6 , wherein the control or adjusting unit is configured such that the temperature of the cold heat exchanger is adjusted to a specified desired value or within a range of desired values. 
   
   
       8 . The refrigerator and/or freezer according to  claim 2 , wherein the control or adjusting unit is configured such that the temperature of the cold heat exchanger is adjusted to a specified desired value or within a range of desired values. 
   
   
       9 . The refrigerator and/or freezer according to  claim 3 , wherein the control or adjusting unit is configured such that the temperature of the cold heat exchanger is adjusted to a specified desired value or within a range of desired values. 
   
   
       10 . The refrigerator and/or freezer according to  claim 9 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation. 
   
   
       11 . The refrigerator and/or freezer according to  claim 8 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation. 
   
   
       12 . The refrigerator and/or freezer according to  claim 7 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation. 
   
   
       13 . The refrigerator and/or freezer according to  claim 6 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation. 
   
   
       14 . The refrigerator and/or freezer according to  claim 4 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation. 
   
   
       15 . The refrigerator and/or freezer according to  claim 3 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation. 
   
   
       16 . The refrigerator and/or freezer according to  claim 2 , wherein the magnetic cooler and/or the pump are configured such that they are running in continuous operation.
