1 is continuously operated for a predetermined time Tmin (for example, 180 min), and cold air is continuously introduced from the cold air inlet 22 of the freezing compartment 18, and the food 21 is comparatively mixed with the heat conduction cooling effect of the metal plate 20 on the bottom surface. Freeze in a short time. Then, after a lapse of a predetermined time, the operation returns to normal stable operation.

あった。However, in the above structure, when the quick freeze switch 24 is pressed, the compressor 9 and the blower 11 are continuously operated for a predetermined time, and the quick freezing chamber 18 is operated.
Since a certain amount of cold air is continuously fed into the inside of the food 21 and the food 21 is cooled from the outer surface, the cold air is fed into the entire quick freezing compartment 18 regardless of the size and shape of the food 21. When the food 21 is small or has a low height, the cooling efficiency is poor and there is a problem that the freezing time is long.

いう欠点があった。In addition, the food 21 to be frozen is continuously cooled with a constant amount of cold air from the outer surface, and the heat conduction of a metal plate provided on the bottom surface is utilized to accelerate the cooling. Therefore, if the heat conduction of the metal plate cannot be obtained, cooling from the bottom surface cannot be expected, and there is a drawback that the freezing time is long.

に頼ることとなり所望の急凍効果が得られない。As long as the amount of food to be frozen is small and can be accommodated in the area of the metal plate, the food can come into contact with the metal plate, so that heat conduction from the bottom is added to cooling with cool air and a desired freezing effect is secured. can do. However, in general households, food is not always singularly frozen, and due to an increase in bulk buying and the spread of home freezing, a large number of foods can be frozen at one time and are often frozen in a pile. In this case, neither the food below nor the food above can obtain the desired freezing effect. Since the food below contacts the metal plate on the bottom, heat conduction from the metal plate can be obtained, but direct cold air cooling is difficult to obtain because the food overlaps on it. Further, since the bottom surface of the food on the top overlaps with the food on the bottom, heat conduction from the bottom is not obtained at all, and the desired quick-freezing effect cannot be obtained because only the cold air cooling is used.

かるため、食品の品質を損なうという課題があった。When freezing foods, it is important to quickly pass through the maximum ice crystal formation zone of -1 to -5 ° C, but when frozen by stacking, the freezing time of the upper and lower foods (maximum Since it takes a long time to pass through the ice crystal formation zone), there is a problem that the quality of food is impaired.

In addition to the structure provided with the temperature detecting means, a vertically movable shelf device on which an inverted L-shaped shelf plate composed of a bottom plate and a back plate is placed is added.

Is variable. At this time, depending on the height of the quick freezing chamber, the back plate of the shelf blocks the cold air introduction port of the quick freezing chamber, and cold air does not flow on the shelf plate. Next, when the quick freezing operation is started, the compressor and the blower are forcedly operated for a certain period of time, a certain amount of cold air is continuously introduced into the quick freezing chamber, and the food is intensively cooled from the outer surface. Since the height of the quick freezing compartment is variable according to the food, efficient cooling can be achieved.

来よりも食品をおいしく冷凍保存することができる。The operation at the time of rapid freezing in such a configuration will be described. When a plurality of foods 21 and 46 are frozen, one food, for example food 21, is installed on the metal plate 29 on the bottom surface in the freezing chamber 25, and the other food, for example food 4
6 is installed on the shelf board 43. At this time, the shelf plate 43 can be arbitrarily moved by the device 32 according to the size of the food. Then, quick freezing is started. Simultaneously with the start, the compressor 9 and the blower 11 are forcibly operated for a certain period of time, and cold air is continuously introduced into the freezing chamber 25. At this time, the shelf board 43
The cold air is continuously introduced from the cold air introduction port 45 into the food 46 installed in the above, and the cold air is continuously introduced into the food 21 installed into the metal plate 29 from the cold air introduction port 27. As a result, both the foods 21 and 46 are cooled from the outer surface and the metal plate also promotes the cooling from the bottom surface, so that a desired frozen state can be obtained and quick freezing can be performed at once without stacking. Become. Even when a plurality of foods are frozen by bulk buying or the like, a quick-freezing effect almost equal to that of freezing a single product can be obtained, and the foods can be frozen and stored more deliciously than before.

【発明の効果】以上のように、本発明の冷蔵庫によると
次のような効果が得られる。 (1)食品の大きさに合わせて急速冷凍室の高さが調整
できるため、常に食品に集中して冷気が導入されるよう
になり、冷却の効率がよくなる。 (2)複数の食品を積み重ねずに一度に急速冷凍するこ
とができる。As described above, according to the refrigerator of the present invention, the following effects can be obtained. (1) Since the height of the quick freezing compartment can be adjusted according to the size of the food, cold air is always introduced into the food in a concentrated manner, and cooling efficiency is improved. (2) A plurality of foods can be rapidly frozen at once without stacking.
