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 a container for rapidly freezing food and a structure of a freezer compartment.

[0002]

2. Description of the Related Art In a refrigerator, for example, as shown in FIG. 6, the inside of a heat insulating box 1 composed of an outer box 2, an inner box 3, a heat insulating material 4 and the like is formed by two upper and lower heat insulating partitions 5, 6 in a refrigerator compartment. , A freezer compartment 8 and a vegetable compartment 9, and two containers 32, 33, which can be taken in and out with the opening and closing of the doors 21, 22 above and below the freezer compartment 8, to supply cold air behind the freezer compartment 8. Mouth 3
0a, 30b, the containers 32, 3
There is one that freezes the food in 3.

By the way, when food is slowly frozen, the moisture contained in the food becomes large ice crystals, which destroys the cell membrane of the food, so that the delicious components of the food escape from the broken cell membrane during thawing. Are known. Therefore, in a conventional refrigerator, a metal tray 31 having good heat conductivity is provided on the inner bottom surfaces of the containers 32 and 33 as shown in FIG.

[0004]

However, even if the metal tray 31 is provided in the containers 32 and 33 as described above, when the food is newly stored, the container 3 is not used.
If there are foods already stored in the trays 2 and 33, the tray 31 cannot be effectively used unless the foods are removed, and the cool air supplied from the cool air supply ports 30a and 30b is supplied to the containers 32 and 33. When there are many foods in the containers 32 and 33, the cool air does not reach the tray 31 and the tray 31 itself is indirectly cooled. There was a problem that the purpose was not fulfilled. Therefore, an object of the present invention is to provide a refrigerator that can effectively use a tray for quick freezing of food.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can be put in and out of a freezer compartment formed in a heat insulating box with opening and closing of a door. In a refrigerator provided with at least one container provided with a metal tray and supplying cool air from a cool air supply port formed in a rear cool air distribution chamber, a cool air passage is formed between front and rear bottoms of the container. At the same time, a cool air supply port corresponding to the cool air passage is provided in front of the cool air distribution chamber, and cool air discharged from the cool air supply port is passed through the cool air passage.

Further, in the case where two containers having the cool air passages are provided above and below the freezing chamber, two cool air supply ports corresponding to the two cool air passages are provided in front of the cool air distribution chamber. Configuration.

[0007] Further, an opening is provided on the inner bottom surface of the container.

Further, the tray is made of aluminum or stainless steel plate.

As another means, at least one container provided with a metal tray at the inner bottom thereof can be inserted into and removed from the freezer compartment formed in the heat insulating box with opening and closing of the door. In the refrigerator configured to supply cool air from a cool air supply port formed in the cool air distribution chamber, an opening is provided in a bottom surface of the container, and a back side of the tray is exposed to the freezer.

[0010]

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a side view showing the internal configuration of the entire refrigerator. Reference numeral 1 denotes a heat insulating box including an outer box 2 made of a steel plate, an inner box 3 made of a synthetic resin, and a heat insulating material 4. The interior (inner box 3) of the heat-insulating box 1 is divided into an upper refrigerator compartment 7, a central freezer compartment 8, and a lower vegetable compartment 9 by upper and lower two heat-insulating partitions 5, 6, and the refrigerator compartment 7 is provided. Is provided with a chilled chamber 10, and a partition body 11 is provided between the left and right sides of the opening of the freezing chamber 8 to partition the opening vertically.

An evaporator 13 for generating cool air and a cool air for each chamber 7 are provided in a cool air generating chamber 12 provided on the rear side of the freezing chamber 8.
A blower 14 for supplying and circulating to 8, 9, 10 is arranged, and a heater 15 for defrost which is turned on at the time of defrost and a heater 15 for defrost are protected from defrost water in a lower space of the evaporator 13. An aluminum protective cover 16 is provided for the refrigerator body 1.
A compressor 18 is provided in a machine room 17 formed at a lower rear portion of the
Evaporating dish 19 for evaporating defrost water flowing down from evaporator 13
Etc. are arranged.

Numerals 20 to 23 denote doors of the refrigerator compartment 7.
0 is pivotally supported on one side so that it can be opened and closed freely.
The doors 21, 22 and the door 23 of the vegetable compartment 9 are all drawer-type, and containers 27, 28, 29 supported respectively by frames 24, 25, 26 are integrally provided behind the drawers,
A cool air distribution chamber 30 for distributing cool air generated by the evaporator 13 to the respective chambers 7, 8, 9, and 10 is provided behind the freezing chamber 8, and a plurality of cool air supply ports are formed on the front surface thereof. .

Hereinafter, the relationship between the container 27 (28) in the freezer compartment 8, the tray 31 provided in the container 27 (28), and the cool air supply port to the freezer compartment 8 will be described. . 2A and 2B show a container 27 (28) for the freezer compartment 8 and a tray 31 made of, for example, a stainless steel plate disposed on the inner bottom surface thereof. In the container 27 shown in A), a cool air passage 27a is formed before and after the bottom. Further, in the container 27A shown in FIG. 2B, a cold air passage 27a is formed between the front and rear of the bottom, and
An opening 27b is provided in the center of the inner bottom surface of 7A, and the back side of the tray 31 arranged in the container 27 is exposed to the cool air passage 27a.

FIG. 3 shows a use form of the container 27 described with reference to FIG. 2A. In the front of the cool air distribution chamber 30, a cool air supply port 30a facing the upper opening surfaces of the containers 27 and 28 is provided.
In addition to 30b, a cool air supply port 30c corresponding to the cool air passage 27a of the container 27 is provided, and cool air discharged from the cool air supply port 30c passes through the cool air passage 27a of the container 27. Therefore, the tray 31 arranged on the inner bottom surface of the container 27 can be cooled faster, and the freezing of the food can be accelerated. If the container 27A shown in FIG. 2B is used instead of the container 27, the tray 31 in the container 27A is exposed to the cool air passage 27a, so that the cooling speed can be further increased compared to the former. it can.

FIG. 4 shows an example in which the containers 27, 28 or 27A, 28A shown in FIG. 2A or 2B are used above and below the freezing room 8, and the containers 27, 28

In addition to the cold air supply port 30c corresponding to the cold air passage 27a,
A cool air supply port 30d corresponding to the cool air passage 28a of the container 28 (or 28A) is provided. Therefore, not only the upper container but also the lower container has the cold air passage 28a.
The cold air from the cold air distribution chamber 30 can be circulated directly, and the cooling speed of the food can be increased.

FIG. 5 shows another embodiment of the container provided in the freezer compartment 8, which is characterized in that the bottom of the container 27B (28B) has a cold air passage 27a (as described above). 28a), there is no opening 27b at the bottom center
(28b) is provided so that the back side of the tray 31 is exposed in the freezer compartment 8. With such a configuration, since the tray 31 is directly cooled by the cool air in the freezer compartment 8, the speed of cooling the food in the container 27B (28B) can be increased, and the container 27B (28
The molding of B) is easy.

[0017]

According to the present invention, the food in the container is cooled from above and below by rapidly cooling the tray in the container and supplying cool air to the upper opening surface of the container. Thus, the food can be frozen in a short time.
