Claims (2)
- 冷凍庫の一画に備えることが可能な自動で氷を作り排氷することができる装置であって、製氷皿の各々の氷室において製氷皿の開口面と氷室の内壁に接している部分が始めに凍りその後は開口面側から凍結が進行して製氷皿の底側近傍で凍結が完了する温度分布を積極的に形成する手段を備えた自動製氷装置において、
製氷皿の温度を連続的に検出できるセンサと、該センサによる検出温度を監視し凍結完了直前の氷が氷室の底側近傍に残った気泡を破裂させた際に氷内部の凍結していない僅かな水が吐出することによって発生する一時的な製氷皿の温度変化を検出する検出回路とを備え、該検出回路による製氷皿の温度変化の検出により水の凍結判定を行うことを特徴とする自動製氷装置。 - 前記製氷皿の温度を検出するセンサ以外に、前記製氷皿近傍の周囲温度を連続的に検出するセンサを備え、前記検出回路は、前記両センサのそれぞれの検出温度の温度差から前記製氷皿の温度変化を検出することを特徴とする請求項1に記載の自動製氷装置。
