PURPOSE:To attain accurate and quick response to the displacement of the height of a liquid level by displacing a float according to the vertical movement of a liquid level enclosing the bottom of a case through the operation of a guide section when an enclosed chamber is formed in the case. CONSTITUTION:As an ice 25 grows, the water level in a water tank 18 falls down, and when the water level is higher than a lower end face 7a of the case 7, the float 11 falls down and when the water level is lower than the lower end face 7a, the float 11 falls down according to the water level in the water tank 18. When the float 11 drops to the detected water level 21, a magnet 30 of a leg slide section 10a crosses a reed switch 31 to output a signal representing the end of ice making. Further, the system enters the cycle harvesting the ice 25 on an ice making plate 24 and water supply into the water tank 18 is started. The ice 15 drops off from the ice making plate 24 and when the water supply to the water tank 18 is finished, the system enters again the ice making process and when the float 11 drops to the detected water level 21, the liquid level control is attained again. |
