Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a refrigerator 1 has a box-shaped main body 2 having heat insulating walls on both sides except a front surface, a back surface, a ceiling surface, and a bottom surface. The main body 2 is formed by filling a heat insulating material 5 such as urethane foam between an outer box 3 made of a steel plate and an inner box 4 made of a hard resin material.

The interior of the main body 2 is divided into a refrigerator compartment 6, a vegetable compartment 7, and two freezing compartments 8, 9 by partition walls 21, respectively. The front opening of the uppermost refrigerator compartment 6 can be closed by a rotatable heat-insulating door 10 that can be opened and closed.
The lower vegetable compartment 7, freezer compartments 8 and 9 are drawer-type insulated doors 1.
1, 12 and 13 respectively.

The heat insulating doors 10, 11, 12 and 13 are:
A heat insulating material such as urethane foam is filled between a door outer box made of a steel plate and a door inner box made of a hard resin material.

The refrigerator 1 is provided with a known refrigeration cycle unit (not shown). That is, a compressor provided at the bottom of the main body 2 sucks and compresses the refrigerant to a high temperature and a high pressure, and the condenser condenses a high temperature and a high pressure gaseous refrigerant from the compressor, and the refrigerant has a low temperature and a low pressure by a capillary tube. Is vaporized by an evaporator provided in the cool air supply duct 14.

The cool air cooled by the evaporator is also cooled by a cool air circulating fan (not shown) in the cool air supply duct 14 through the cool air outlet, and the refrigerator compartment 6, the vegetable compartment 7, the two freezing compartments 8, 9 is introduced.

The refrigerator compartment 6 is provided with three shelves 20 on which food can be placed at predetermined intervals, and the food is placed on a partition wall 21 below the lowermost shelf 20. An ice greenhouse 22 for storing at a temperature close to ° C is formed. A door that can be opened and closed is provided on the front surface of the ice temperature chamber 22, and a known sliding storage container 24 (for example, Japanese Patent Laid-Open No. 10-103) is provided in the ice temperature chamber 22.
854, etc.).

That is, in the storage container 24, engagement portions projecting from both sides of the storage container 24 are guided along main guides provided on both side walls of the inner box 4 of the main body 2; Auxiliary guides projecting from both sides of the storage container 24 slide on a support member provided in the storage container 24 and can be put in and out of the ice temperature chamber 22.

As shown in FIGS. 2 and 4, the upper lid 23 has a substantially rectangular shape, and a substantially rectangular concave portion 25 is formed at the center of the upper lid 23. The rear part and both side parts of the 25 are formed with a swelling part 26 which protrudes outward.

The recess 25 has a thaw plate 27 made of a metal material having good heat conductivity, for example, aluminum.
Is placed.

As described above, the thawing plate 27 is disposed in the recess 25.

In this concave portion 25, since cool air (warm air as viewed from frozen food) accumulates, a predetermined refrigeration temperature is maintained.

Further, the upper surface of the thawing plate 27 is cooled by cold air, and the inclined surface 26 provided around the concave portion 25
The cold air enters the recess 25 and the thawing plate 27
The whole is cooled.

At the center of the front part of the concave portion 25, a finger inserting concave portion 32 is formed to extend forward. A finger is inserted into the finger inserting concave portion 32 to lift the thawing plate 27, and the thawing plate 27 is thawed. The plate 27 can be easily removed, and the upper lid 23, the concave portion 25 and the thawing plate 27 can be easily cleaned.

On both sides of the thawing plate 27, resin caps 30 are provided.
Covered by

As shown in FIG. 3 and FIG.
Is an upper lid of the ice greenhouse 22. Therefore, this thawing plate 2
It may adversely affect the ice greenhouse 22 on which hot food is placed.

For this purpose, a lower plate 33 is provided, and
And an air insulation layer is formed between them. Also, the thawing plate 27
The fins are provided at equal intervals on the lower surface of the device to enhance heat dissipation. The cap 30 has ventilation holes 30c corresponding to the spaces between the fins. In addition, the cap 30 is slightly larger than the thawing plate 27 in the vertical direction. Accordingly, the lower portion 30b of the upper portion 30a and the lower portion 30b of the cap serves to lift the thawing plate 27 in the recess 25.

In the case where foods frozen and stored in the freezing compartments 8 and 9 are eaten, the frozen foods are taken out from the freezing compartments 8 and 9 and the concave portions of the upper lid 23 of the ice warming compartment 22 are taken out. It is placed on a thawing plate 27 installed at 25.

Then, the cool air supplied into the refrigerator compartment 6 is
The thawing plate 27 is introduced from the slope 26 and the back surface of the
The thawing plate 27 is brought to a predetermined temperature via the passage 28 between the bottom surface forming the slab 5 and helps the thawing of the food.

By providing the recess 25, the thawing plate 27
Does not move, and since the steps on the upper surface of both the thawing plate 27 and the upper lid 23 can be reduced, large foods can be stably placed.

In the above description, the metal plate has been described as a thawing plate. However, even when it is desired to rapidly cool food at room temperature, the cooling time can be shortened by placing the metal plate on the metal plate 27. it can. Therefore, this metal plate 27
Is not only used for thawing.

In the present embodiment, the upper cover 23 of the ice greenhouse 22 is used.
Although the thawing plate 27 is detachably provided in the concave portion 25, the same effect can be obtained by making each shelf plate 20 installed in the refrigerator compartment 6 on which food is placed have the same structure as the upper lid 23. Is obtained.

In this embodiment, foods and the like are loaded in a refrigerator provided with a refrigerator room 6 to which cool air is supplied from a cool air supply duct and an ice temperature room 22 which is a specific low-temperature room provided below the refrigerator room. A concave portion 25 is formed on the upper surface of the upper lid 23 of the ice temperature chamber 22, which is a flat plate-like portion for mounting, and a thawing plate 27, which is a metal plate, is detachably mounted in the concave portion 25.

Accordingly, the thawing plate 27 can be easily removed and the cleaning is simple. In addition, even when cleaning is performed without removing the thawing plate 27, the surfaces of the thawing plate 27 and the upper lid 23 substantially coincide with each other, so that cleaning is easy. In addition, even when the food is placed, there is no large step between the thawing plate 27 and the other portions, so that the food storage ability does not deteriorate.

The thawing plate 27 has caps 30 on both sides.
It is covered with, so it doesn't hurt by metal edge.

The cap 30 has holes 3 for ventilation.
Since 0c is provided, heat dissipation is improved.

The cap 30 projects below the thawing plate 27 so that the thawing plate 27
, And a cool air passage 28 is formed below the decompression plate 27 to enhance heat dissipation.

The upper surface of the thawing plate 27 has a flat shape, and the lower surface has a non-flat shape such as an uneven shape or a corrugated shape, thereby improving heat radiation.

The provision of the inclined portion 26 around the concave portion 25 enhances the heat radiation.
