Claims
- 1. A combination refrigerator and automatic ice making apparatus comprising a housing in which is located (a) a refrigerator chamber, (b) an auger type ice making unit insulatingly spaced from said refrigerator chamber, (c) a bin for storage of ice only and insulatingly separated from both said auger type ice making unit and said refrigerator chamber, (d) conduit means for passage of ice from said auger type ice making unit to said bin and (e) a cooling system located in said housing comprising a compressor, a condensor and evaporators associated respectively with said refrigerator chamber and said auger type ice making unit, the evaporators for said refrigerator chamber and auger type ice-making unit being connected in parallel through respective changeover valves for refrigerant to the refrigeration system, one of the changeover valves being controlled by a temperature sensitive element for detecting the temperature in the refrigerating chamber, the other of the changeover valves being controlled by an ice detecting switch arranged in the ice-storage chamber, and the evaporator for said refrigerator chamber communicating with a delivery side of the compressor for the refrigerant through a hot gas by-pass line having a hot gas valve which is periodically energized for opening, while all of the changeover valves for the refrigerant are closed, by means of a cam timer.
- 2. The combination according to claim 1, wherein a wet refrigerating chamber is located below said ice storage bin and is cooled by the ice stored therein, being separated from said wet refrigerating chamber by means of an air-pervious partition.
- 3. The combination according to claim 1, further comprising door means for independently gaining access to each of said refrigerator chamber and ice storage bin.
- 4. The combination according to claim 1 wherein said auger-type ice making unit comprises a cooling cylinder formed with an opening at its upper end and provided about its outer periphery with an evaporator of a coil configuration, a water supply pipe communicating with a bottom of the cooling cylinder for supplying water to said cylinder, a shaft with a worm rotatably mounted in said cylinder to scrape off a thin ice layer formed on the inner cylindrical surface of said cylinder and to then move the scraped ice toward the opening, and a driving means for rotating said shaft and said cylinder being provided at its upper open end with an ice compression die for compressing the scraped ice into an ice mass.
