Auger type ice-making apparatus

Abstract

An auger type ice making apparatus adapted for effectively flushing and removing deepended water and precipitates in the water supply pipe and the freezing cylinder during ice making. The apparatus includes a water inlet having a supply valve for supplying ice-making water into the ice-making water tank, a water level switch in the tank, a generally cylindrical freezing cylinder communicating with the inside of the ice-making water tank, a screw shaft rotatably mounted within the freezing cylinder and having a screw edge, a freezing portion including a compressor for supplying a refrigerant to a freezing pipe coiled about the outer periphery of the freezing cylinder, a water supplying pipe between the ice making water tank and freezing cylinder, a water discharge valve in the freezing cylinder, and a control circuit construction including a cleaning timer for controlling the water supply valve and the water discharge valve the cleaning timer and the water level switch are operative to open the water discharge valve during the time that the water supply valve is closed, whereby the inside of said water supply pipe and the freezing cylinder is cleaned with an amount of the ice-making water within the operating range of the water level switch in the ice-making water tank.
