Abstract

896,723. Refrigerators. GENERAL MOTORS CORPORATION. Feb. 16, 1961 [Feb. 17, 1960], No. 5726/61. Class 29. A refrigerator has a freezer compartment 30 and a storage compartment 32 and a vertically disposed plate type evaporator 34 in the storage compartment with zig-zag fins 38 bonded to its rear face. A forced-air system for the freezer compartment 30 comprises a passageway 54 beneath the freezer compartment 30 with a front opening 60, two vertical side passages 44 and 46 containing some of the fins 38, a central vertical passage at the centre part of the evaporator 32 containing the rest of the fins 38, and a blower unit 66 with an inlet 68 which discharges cooled and dried air upwardly through a discharge duct 74 and an opening 76 in the wall 72 of the freezer compartment 30. A natural air-circulating system for the storage compartment 32 comprises a horizontal passage 90 at the top of the storage compartment leading to a vertical duct 96 which passes down the front face of the evaporator 34. The machinery compartment 127 is located below the bottom wall 26 and contains a motor-compressor unit 129, a condenser 131 and a capillary tube restrictor 133, illustrated in Fig. 7 (not shown) leading to the evaporator 34. Frost accumulates periodically on both sides of the evaporator 34 and this is removed by an electric heater fitted to the fins 38. A control system, Fig. 6 (not shown) incorporates a timer motor which periodically de-energizes the compressor motor and the blower unit and energizes the heater, defrosting being terminated by a predetermined rise in temperature of the evaporator. A drip collector 123 is situated below the evaporator 34 from whence the melt water is drained.
