Abstract: Disclosed is an arrangement of an ice fullness detector within an ice making machine composed of an ice making unit and an ice reservoir upon which the ice making unit can be separably stacked, wherein ice cakes formed within the ice making unit are discharged into the ice reservoir through an opening defined within the bottom wall of the ice making unit so as to be stored within the reservoir.

Abstract: There is provided an ice discharge section in an auger type ice making machine wherein an evaporator connected to a refrigerating system is sealingly wound along the outer periphery of a cylindrical refrigerating casing and the thin ice formed upon the inner wall surface of the refrigerating casing is scrapped off by an auger rotatably supported within the interior of the refrigerating casing so as to transfer the resulting ice flakes upwardly so that the compressed ice obtained by compressing these ice flakes by an extruding head may be discharged into an ice storage chamber via an ice discharge passage provided at the top of the refrigerating casing, characterized in that an ice transfer passage disposed within the interior of the ice storage chamber is connected to an opening of the ice discharge passage, an ice transfer passage having a drainage portion is disposed in the area immediately downstream of the opening and has an upwardly inclined surface continuing after the drainage portion, and a water coll

Abstract: In an automatic ice making machine which comprises a freezing chamber formed to define a plurality of open bottom freezing cells, a water plate provided under the freezing chamber for supplying water to be frozen to by spraying the same into the freezing cells, a water tank provided under the water plate for storing a necessary amount of water to be frozen for one freezing cycle, a water inlet valve connected to a feed pipe for supplying water to the water tank, and a water inlet valve controlling timer circuit for controlling the opening and closing of the water inlet valve, and wherein during a defrosting operation, the water plate and the water tank are caused to be inclined downwardly so as to discharge ice cubes the water inlet valve controlling timer circuit comprises a first means for permitting the water inlet valve to open for a first set period of time, a second means for permitting the water inlet valve to open for a second set period of time which is shorter than the first set period of time, and
