Abstract
A refrigeration appliance is provided which has a freezer compartment, a fresh food compartment and a refrigeration system for cooling the two compartments. Two evaporators operating at different temperatures, or a single evaporator operating at sequentially different temperatures is used in the refrigeration system to provide the cooling of the two compartments. An ice making device is provided in the fresh food compartment, thermally associated with the evaporator used to cool the fresh food compartment operating at a warmer temperature, such that ice is formed and stored in the fresh food compartment. Dispensing means extending through the door of the fresh food compartment are provided to allow for dispensing of ice through the fresh food compartment door.
Claims17
A refrigeration appliance comprising:
- a freezer compartment maintained at a temperature below 0.degree. C.;
- a fresh food compartment maintained at a temperature above 0.degree. C. a door to said fresh food compartment;
- a refrigeration system including a first evaporator operating at a first temperature for use in cooling said freezer compartment and a second evaporator operating at a second, higher evaporating temperature for use in cooling said fresh food compartment;
- means for dispensing water onto a surface thermally influenced by said second evaporator in order to reduce the temperature of said water below 0.degree. C. and to cause it to solidify into ice;
- and
- means for dispensing said ice from said surface to a point of utilization which is accessible through an aperture located in said door to said fresh food compartment.
A refrigeration appliance comprising:
- a freezer compartment maintained at a temperature below 0.degree. C.;
- a fresh food compartment maintained at a temperature above 0.degree. C. a door to said fresh food compartment;
- refrigeration means for sequentially cooling each of said compartments, said refrigeration means operating at a first temperature to cool said freezer compartment and operating at a second higher temperature to cool said fresh food compartment;
- means for dispensing water onto a surface thermally influenced by said refrigeration means while said refrigeration means is being used to cool said fresh food compartment in order to reduce the temperature of said water to below 0.degree. C. and to cause said water to solidify into ice;
- and
- means for dispensing said ice from said surface to a point of utilization which is accessible through an aperture located in said door to said fresh food compartment.
A refrigeration appliance comprising:
- a first compartment accessible through an openable door for storing foods in a frozen state;
- a second compartment accessible through a second, separately openable door for storing foods in a chilled, but not frozen state;
- refrigeration means for maintaining said first compartment at a temperature below 0.degree. C. and for maintaining said second compartment at a temperature in the range of 5.degree. to 15.degree. C.;
- means in said second compartment for freezing water into ice;
- and
- dispensing means in said door of said second compartment for dispensing said ice to the exterior of said door without requiring opening of said door.
