Domestic Refrigerating Appliance with an Evacuatable Storage Compartment

Abstract

A domestic refrigerating appliance comprising a heat-insulated inner area, a refrigerating machine using a thermodynamic cycle for refrigerating the inner area, a vacuum pump and a first compartment which is separated from the inner area and which can be evacuated by means of the vacuum pump. The vacuum pump produces pressure inside the first compartment, said pressure being lower than the vapor pressure of water at the temperature of the compartment.

       13 . A domestic refrigerating appliance comprising: 
 a heat-insulated inner area;    a refrigerating machine using a thermodynamic cycle for refrigerating the inner area;    a vacuum pump;    a first evacuatable compartment which is separated from the inner area and which can be evacuated by means of the vacuum pump; and    wherein the vacuum pump produces a final pressure within the first compartment below the vapor pressure of water at the temperature within the first compartment.    
   
   
       14 . The domestic refrigerating appliance according to  claim 13 , wherein the final pressure is below 6 mbar.  
   
   
       15 . The domestic refrigerating appliance according to  claim 13 , further comprising an evacuation connection between the first compartment and the vacuum pump, the vacuum pump developing a suction capacity of at least 0.5 l/s at a pressure prevailing in the first compartment below the vapor pressure of water at the temperature of the compartment.  
   
   
       16 . The domestic refrigerating appliance according to  claim 13 , further comprising a second evacuatable compartment which is in direct thermal contact with the first compartment.  
   
   
       17 . The domestic refrigerating appliance according to  claim 16 , wherein the first compartment can be evacuated independently of the second compartment.  
   
   
       18 . The domestic refrigerating appliance according to  claim 17 , wherein the suction capacity of the pump at an evacuation connection of the second compartment is lower than at that of the first compartment.  
   
   
       19 . The domestic refrigerating appliance according to  claim 16 , wherein the first and the second compartments are surrounded by a common wall.  
   
   
       20 . The domestic refrigerating appliance according to  claim 13 , wherein the first compartment contains a hydrophilic porous material.  
   
   
       21 . The domestic refrigerating appliance according to  claim 13 , further comprising a condensate trap is connected to the vacuum pump.  
   
   
       22 . The domestic refrigerating appliance according to  claim 21 , further comprising an evaporation tray into which the condensate trap drains.  
   
   
       23 . The domestic refrigerating appliance according to  claim 22 , wherein the evaporation tray is heated by heat loss of the refrigerating machine.  
   
   
       24 . The domestic refrigerating appliance according to  claim 13 , wherein the domestic refrigerating appliance includes a refrigerator.
