Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly to the structure of a container and a freezer compartment for freezing and storing food.

[0002]

2. Description of the Related Art In a refrigerator, for example, as shown in FIG. 1 and FIG. 4 or FIG. 5, the inside of a heat insulating box 1 made up of an outer box 2, an inner box 3, a heat insulating material 4 and the like is divided into two upper and lower heat insulating partitions 5. , 6 are divided into a refrigerating compartment 7, a freezing compartment 8 and a vegetable compartment 9, and two containers 27 and 28 that can be taken in and out with opening and closing of the doors 21 and 22 are provided above and below the freezing compartment 8 to freeze the compartment. There is one in which the food in the containers 27, 28 is frozen by the cool air supplied from the cool air supply ports 35, 35 'at the rear of the chamber 8.

By the way, when a food is slowly frozen, the water contained in the food becomes large ice crystals, which destroy the cell membrane of the food, so that the umami component of the food escapes from the broken cell membrane at the time of thawing. Are known. Therefore, in some conventional refrigerators, a metal tray 37 having good thermal conductivity is provided on the inner bottom surfaces of the containers 27 and 28 as shown in FIG. 4 in order to quickly freeze food.

However, as described above, the containers 27, 2
Even if the metal tray 37 is provided in the tray 8, if the food is already stored in the containers 27 and 28 when the food is newly stored, the tray 37 is not removed unless the food is removed. , And the cold air supplied from the cold air supply ports 35, 35 ′ flows toward the upper opening surface of the containers 27, 28, and the ventilation holes 38 and Passing the outside of the containers 27, 28, from the outside bottom of the containers 27, 28 to the rear cool air return ports 36, 3
Since there is a lot of food in the containers 27 and 28, the cold air does not reach the tray 37 and the tray 37 itself is indirectly cooled, so that the food in the center part may not be cooled quickly. Had some problems.

Further, as shown in FIG. 5, the containers 27 and 28 are
There is also a conventional example in which the ventilation holes 32 and 32 'are provided on the bottom surface of the container. However, in this case, depending on the food to be stored, water drops or the like may leak through the ventilation holes 32 and 32' and freeze on the bottom wall of the refrigerator. ,
The containers 27 and 28 cannot be pulled out, or the container 2
There is a problem that noise may occur when pulling out 7, 28.
