    Abstract: PURPOSE:To avoid a wasteful defrosting instruction by selecting the number of input pulses by the atmospheric temperature or humidity in counting the operation time of a compressor by an electornic counter. CONSTITUTION:Frequency divider 2 devides the frequency of pulse source 1 by half, and atmospheric condition input terminal detects the atmospheric temperature so that, for example, signal 1 enters it when the atmospheric temperature is 15 deg.C or above and signal 0 enters it when it is below 15 deg.C. When the power source is turned on, first counter 8 is reset, and subsequently, or at the same time, the power source impression signal is input from power source impression signal input terminal 9 to flip-flop 10, and signal 1 is output. By this, corresponding to the operation of the compressor, the pulse is input to counter 8 via AND circuit 4, and when the cumulative operation time of the compressor becomes, for example, 8 hours, defrosting signal 12 is output from counter 8. After the completion of defrosting, the input of counter 8 is subjected to the control of the atmospheric condition input.

    Abstract: PURPOSE:To obtain clean, relatively hard, and tasty ice by preparing ice-making cycle in which water flows on the surface of an ice-making element and controlling the flow speed so as to be delayed in order from the start to the end of ice-making. CONSTITUTION:An ice-making element 2 is arranged aslant in the upper part to the one side inside the body 1. Ice-making cycle is formed in which the water for ice- making is circulated on the ice-maing element 2 by a ram 4 arranged in a water tank 3. An ice-making completion detecting device 6 which performs switching when ice board has a prescribed thickness, is arranged in the vicinity to the ice- making element 2, and switches ice-making cycle and water-releasing cycle. An ice-storage amount detecting device 9 controls the operation and stop of all ice-making functions. A variable resistor 10 connected in series with the motor 4 of the ram 4 increases resistance value succesively from the time of start through timer control and controls the flow speed through ice-making cycle, and clear,hard, and tasty ice can be made.
