The present invention provides an ice storage detection switch for detecting an ice level in an ice storage chamber of an ice making machine including: a magnet lever rotatably fitted to the switch lever, for holding the magnet so that the magnet is located in a vicinity of the reed switch when the switch lever is not pressed; and a projecting portion formed on the switch case to be located between a rotational center of the magnet lever and the reed switch, the magnet separating from the reed switch through abutment of the magnet lever on the projecting portion and rotation of the magnet lever when the switch lever is pressed.

Ice storage detection switch

A cooling unit wherein devices are divided so as to be installed in each of an outdoor unit and indoor unit, for downsizing the indoor unit and reducing its pipe-line cost. The cooling unit disposes a compressor, a condenser and a liquid receiver R in the outdoor unit, and disposes an expansion means and an evaporator in the indoor unit. The outdoor unit comprises a first bypass pipe closed by a first bypass valve so as to open/close freely. The indoor unit comprises a second bypass pipe, which is closed by a second bypass valve so as to open/close freely. The units are connected by a liquid pipe used as a supply line for refrigerant or hot gas by selecting a refrigerant supply line among the bypass valves and the open/close valves, and by a gas pipe communicating the evaporator to the compressor.

Cooling unit

A water storage tank assembly is accommodated so that it can be pulled out and extended over an ice making chamber and a machine chamber by passing through a lower portion of a partition wall part by which the ice making chamber is separated from the machine chamber In the water storage tank assembly, a cube guide is attached to a water storage tank on the side of the ice making chamber. On the other hand, a pump motor and a float switch are attached to the water storage tank on the side of the machine chamber. The water storage tank assembly can be pulled out so that the water storage tank, the cube guide, the pump motor and the float switch, etc. can be completely cleaned to all corners.
