〈技術分野〉
本考案は、特に、冷凍室等の扉の閉め忘れを防
止するための冷凍冷蔵庫に関するものである。[Detailed Description of the Invention] <Technical Field> The present invention particularly relates to a refrigerator-freezer for preventing people from forgetting to close the door of a freezer compartment or the like.
〈従来技術〉
従来の冷凍冷蔵庫は、子供がよく開閉した後、
うまく閉まつてなくて冷凍食品が解けている時が
有り、また最近では冷却器が凍結していてまつた
く冷えないことも有つた。<Prior art> Conventional refrigerator-freezers, after being opened and closed often by children,
There have been times when the refrigerator has not closed properly and frozen food has thawed, and recently there have been times when the refrigerator has frozen and not cooled down properly.
これは、フアン式冷凍冷蔵庫ではドアースイツ
チが冷蔵庫側と冷凍庫側についていてどちらかで
も開くとスイツチがOFFになりフアンが止まる、
しかし、冷凍サイクルは、かえつて庫内温度が高
くなり動きつづける。そのため、冷却器に霜が付
着していく。この時点で冷凍室扉の開いているの
に気付いて閉めても冷却器の隙間に霜が一杯付い
ているためにフアンが回つても冷気の循環ができ
なくなり、庫内が冷えなくなつてしまう。そのた
め、使用者は故障したと錯覚する場合もある。 This is because in a fan-type refrigerator-freezer, the door switch is on the refrigerator side and the freezer side, and if either is opened, the switch turns OFF and the fan stops.
However, the refrigeration cycle continues to operate, increasing the temperature inside the refrigerator. As a result, frost builds up on the cooler. At this point, you notice that the freezer compartment door is open, and even if you close it, there is so much frost in the cracks in the cooler that even if the fan turns, it will not be able to circulate cold air, and the compartment will no longer be cool. . Therefore, the user may be under the illusion that there is a malfunction.
〈目的〉
本考案は、上記に鑑み、扉の閉め忘れによる故
障を防止して、冷凍冷蔵食品の腐敗を防止し得、
