Abstract
An ice making machine in which upon starting of an ice making operation, a water level detecting switch starts measurement, and a water-supply-stop time T1 is compared with a reference time T2. When the water-supply-stop time T1 is not longer than the reference time T2, it is determined that the ice making machine is an excessive-ice-making state, and control is performed so as to reduce the RPM of a fan motor for cooling a condenser.
Claims16
An ice making machine comprising:
- an ice making portion;
- a water supply tank for supplying ice making water to the ice making portion;
- a freezing circuit including an evaporator for cooling ice making water supplied to the ice making portion to make ice;
- consumption time detecting means for detecting time in which a fixed amount of ice making water is consumed;
- and
- a control circuit which compares the consumption time detected by the consumption time detecting means with a reference time and adjusts the freezing capacity of the freezing circuit when the detected consumption time is shorter than the reference time.
