Abstract

A refrigerator is formed with a freezer compartment beneath a cold storage compartment for the purpose of adopting a single evaporator for two temperature compartment by disposing an evaporator between two compartments, further for operating a freezer compartment with a natural convection and a cold storage compartment with a forced circulation. Therefore a door of a freezer compartment is opened downwardly for the requirement of above facilities and a automatic ice making device which is settled on the shelf of an evaporator drops the ices into the ice pocket fixed to the door back during the door is closed. A door handle of "∩" shaped in section is adopted for use with downward opening door of a freezer compartment.

Claims

1. A refrigerator having a cold storage compartment and a freezer compartment located below the cold storage compartment, the freezer compartment being provided with a door which opens downwardly and closes upwardly, and said door being provided with a handle, wherein said door has lever means connected thereto, roller means being operatively associated with said lever means, guide rail means being provided on the interior of said freezer compartment and having a sliding surface which cooperates with said roller means, wherein the sliding surface of said guide rail means defines two connected arcs whose centers are displaced from each other, and pivot means connecting said door with said freezer compartment for permitting said door to be opened and closed by moving said roller means from one arc on the sliding surface to the other arc on the sliding surface and, wherein said pivot means comprises an axle pin on one of said door and freezer compartment and a female member with an oblong hole on the other of said door and freezer compartment to receive the axle pin such that one end of the oblong hole defines the center for one arc and another end of the oblong hole defines the center for the other arc so that the door can be opened and closed in a two-step action.
