機構２４乃至２６により本体１にロックされているが、
そのロック力に抗して引くことにより、ドア２１乃至２
３は容易に開放することができる。The doors 21 to 23 are opened when storing or taking out food in the storage chambers 3 to 5. The doors 21 to 23 are locked to the main body 1 by lock mechanisms 24 to 26,
By pulling against the locking force, the doors 21 to 2
3 can be easily opened.
食品を収容又は取り出した後、ドア２１乃至２３を閉じ

ロックされる。When the doors 21-23 are closed after storing or removing the food, they are automatically locked by the locking mechanisms 24-26.
これらのロック機構として、例えば鉄片と磁石を用いる
ことができる。For example, iron pieces and magnets can be used as these locking mechanisms.
次に、スイッチ２７ａをオンすると、制御回路５３は収
容室５の内部の減圧動作を実行させる。Next, when the switch 27a is turned on, the control circuit 53 causes the interior of the storage chamber 5 to be depressurized.
このとき制御回路５３は先ずロック機構２６を制御じ、
ドア２３を開放不能にロックさせる。このためロック機

The door 23 is locked so that it cannot be opened. For this reason, the locking mechanism 26 includes a plunger, a solenoid, etc. in addition to an iron piece or a magnet. When the plunger or the like operates, an arm or the like (not shown) is moved and the door 23 is mechanically locked.
このとき制御回路５３は表示器２８を駆動し、収容室５
が減圧されていることをＬＩＥＤを点灯させる等して表
示させる。At this time, the control circuit 53 drives the display 28 and
The fact that the pressure is being reduced is indicated by lighting up the LIED.
次に、制御回路５３は真空ポンプ１３と弁１５゜１６を
制御し、収容室５の内部の空気を弁１５、弁１６を介し
て外部に排出させる。これにより収容室５の内部は減圧
される。Next, the control circuit 53 controls the vacuum pump 13 and the valves 15 and 16 to exhaust the air inside the storage chamber 5 to the outside via the valves 15 and 16. As a result, the pressure inside the storage chamber 5 is reduced.
検出器４４は収容室５の内部の気圧を検出している。こ
の検出気圧が予め設定しである所定の基ｆ４ＩＩ値以下
になったとき、弁１５．王６が閉じられ。The detector 44 detects the atmospheric pressure inside the storage chamber 5. When this detected atmospheric pressure becomes less than a predetermined base f4II value, the valve 15. King 6 is closed.
減圧動作は中止される。The decompression operation is aborted.
これにより、収容室５は冷却器１１により冷却されると
同時に、真空又はそれに近い状態に減圧される。その結
果、酸素が無いか、又はあっても極めて希薄な状態とな
り、細菌の繁殖が著しく困難な状態になる。従って、食
品の腐敗の進行が抑制される。As a result, the storage chamber 5 is cooled by the cooler 11, and at the same time, the pressure is reduced to a vacuum or a state close to vacuum. As a result, there is no oxygen, or even if there is oxygen, it is extremely diluted, making it extremely difficult for bacteria to grow. Therefore, the progress of food spoilage is suppressed.
収容室５の冷却温度は、食品を冷凍しない程度の温度（
例えば−４℃乃至３℃）に設定されているので、食品の
細胞が破壊されるようなことが防止さオシる。The cooling temperature of the storage chamber 5 is a temperature that does not freeze the food (
For example, the temperature is set at -4°C to 3°C), which prevents the cells of the food from being destroyed.
次に、収容室５から食品を取り出すとき、スイッチ２７

使用者は減圧が解除されたことを知ることができる。Next, when taking out the food from the storage chamber 5, the switch 27
b is turned on. At this time, the control circuit 53
3 and valve 15.16, and external air is passed through valve 16.1.
5 into the storage chamber 5. When the air in the storage chamber 5 reaches 1 atm or a value close to it, the control circuit 53 drives the display 28 and lights up the LED to display a different display than when the pressure is reduced. This results in
The user can know that the reduced pressure has been released.
またこのとき制御回路５３はロック機構２６を制御し、
プランジャ等の励磁を中止し、機械的なロックを解除さ
せる。その結果、収容室３，４における場合と同様に、
磁石と鉄片による軽いロックだけとなり、ドア２３が開
放可能となる。Also, at this time, the control circuit 53 controls the lock mechanism 26,
Stop excitation of the plunger, etc., and release the mechanical lock. As a result, similar to the case in containment rooms 3 and 4,
The door 23 can be opened with only a light lock using a magnet and iron piece.
減圧時ドア２３を開放不能にロックしなかったり、表示

ある）旨を表示させるようにするのが好ましい。If the door 23 is not locked so that it cannot be opened at the time of depressurization, or if the display 28 is not made to display depressurization, air will suddenly enter the interior of the containment chamber 5 if the door 23 is forcibly opened. , there is a risk that an unexpected accident may occur. Therefore, it is preferable to lock the door 23 so that it cannot be opened when the pressure is reduced, and to display on the display 28 that the door 23 cannot be opened (the pressure is being reduced).
また、検出器４４を設けず、減圧動作開始後又は減圧動
作解除開始後、所定の時間が経過したことを検出して、
真空ポンプ１３や弁１５，１６の動作を制御することも
可能である。しかしながらそのようにすると、何等かの

動作させるようにすることができる。In addition, the detector 44 is not provided, and it is detected that a predetermined time has elapsed after the start of the pressure reduction operation or after the start of the release of the pressure reduction operation,
It is also possible to control the operation of the vacuum pump 13 and valves 15 and 16. However, if this is done, and for some reason the decompression operation is not performed reliably, the food inside will be the same as if it were stored in storage chamber 3, which is a normal refrigerator, and the shelf life will be poor. There is a risk that Therefore, it is preferable to detect the actual atmospheric pressure. In addition, if this is done, if the pressure becomes high after pressure reduction due to leakage of the valves 15 and 16, etc., the vacuum pump 13 will be automatically operated at any time to maintain the predetermined pressure. can do.
