Abstract: The object is to provide an ice making water tank for an automatic ice making machine capable of stabilizing the operation of a float switch. As a means for achieving the object, there is provided an overflow portion 64 having a wall portion 58 to define a maximum water storage level of ice making water, and a raised-bottom portion 60 to discharge excess ice making water that has overflowed the wall portion 58 to the outside through a discharge port 62 on a side near the outside of a tank portion 52 of an ice making water tank 32. Furthermore, a partition member 68 is removably disposed on the overflow portion 64 side with respect to the disposed position of the circulation pump 14 in the tank portion 52 to divide the inside of the tank portion 52 into two regions, and to allow ice making water near the bottom portion 56 to flow between the two regions. In addition, a float switch 26 is disposed between the partition member 68 and the overflow portion 64 in the tank portion 52.

Abstract: 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.

Abstract: 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.

Abstract: A water storage tank assembly 12 is accommodated so that it can be pulled out and extended over an ice making chamber 1 and a machine chamber 2 by passing through a lower portion of a partition wall part 4 by which the ice making chamber 1 is separated from the machine chamber 2. In the water storage tank assembly, a cube guide 16 is attached to a water storage tank 13 on the side of the ice making chamber. On the other hand, a pump motor 14 and a float switch 15 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.
