構成される。2. Description of the Related Art A refrigerator with an automatic ice maker comprises an automatic ice maker installed in a freezer compartment, a water supply bottle and a water supply pump installed in a refrigerator compartment, and a water supply pump for supplying water. .
【０００３】ここで、給水パイプの先端に残留した水滴
が時間経過と共に、氷結成長してパイプ開口部を塞ぐ可
能性が大きい。Here, there is a high possibility that the water droplets remaining at the tip of the water supply pipe will freeze and grow to block the pipe opening over time.
【０００４】このため、給水パイプを保温して先端に残
留した水滴の氷結成長を防止するための保温用ヒータは
必要不可欠である。For this reason, a heat retaining heater is indispensable for keeping the water supply pipe warm and preventing freezing growth of water droplets remaining at the tip.
【０００５】一方、冷蔵庫は近年付加機能が多様化し、
例えば急冷却、急冷凍などが付加され前記給水パイプが
凍結し易い状況下にあり、給水パイプの保温に対する条
件が厳しくなっている。On the other hand, refrigerators have been diversified in additional functions in recent years,
For example, rapid cooling, rapid freezing, etc. are added, and the water supply pipe is in a state of being easily frozen, and the conditions for keeping the temperature of the water supply pipe severe.
【０００６】このため、給水パイプ先端の水滴の氷結成
長は前記のあらゆる条件においても発生を防がなければ
ならず、必然的に保温用ヒータの容量アップが生じてく
る。Therefore, it is necessary to prevent the freezing growth of water droplets at the tip of the water supply pipe under any of the above-mentioned conditions, which inevitably leads to an increase in the capacity of the heater.
【０００７】しかし、保温用ヒータは、前記の如く冷凍
室内に配設されるため、容量の増加は冷蔵庫の熱負荷の
増加しかるに冷却性能の低下、消費電力の増加というデ
メリットを生ずる。However, since the heat-retaining heater is arranged in the freezer compartment as described above, an increase in capacity causes a demerit such as a decrease in cooling performance and an increase in power consumption although the heat load of the refrigerator increases.
【０００８】保温用ヒータによる冷蔵庫の熱負荷を軽減

く離氷モータの動作時のみに保温用ヒータを通電し、そ
れ以外の時はヒータをＯＦＦする方法がある。As a method of reducing the heat load of the refrigerator by the heat-retaining heater, the heat-retaining heater is energized only when the ice-breaker motor is operating, as in Japanese Utility Model Laid-Open No. 50-67466, and otherwise the heater is turned off. There is a way to do it.
【０００９】しかし上記の方法に於いては、ヒータへの
通電時間が短く、給水パイプ先端の水滴残留、氷結成長
を防ぐことが困難である。However, in the above method, it is difficult to prevent water droplets remaining at the tip of the water supply pipe and freezing growth due to the short energization time to the heater.

【発明が解決しようとする課題】給水パイプ先端の氷結
成長を防止するための保温用ヒータの容量増大は冷凍室
内への熱侵入となり、冷蔵庫の冷却性能を低下させる原
因となる。An increase in the capacity of the heat retaining heater for preventing freezing growth at the tip of the water supply pipe causes heat to enter the freezing compartment, which causes the cooling performance of the refrigerator to deteriorate.
【００１１】そのため、冷蔵庫のあらゆる使用状態に於
いても給水パイプ先端での氷結成長を生ずることがな
く、且つ必要最小限の容量に抑えられることが必要とな
ってくる。For this reason, it is necessary that the freezing does not occur at the tip of the water supply pipe even when the refrigerator is used in all conditions, and that the capacity is kept to the minimum necessary.
