[0008]

When observing the configuration of each storage room of the conventional refrigerator shown in FIG. 7 or FIG. 8 and the positional relationship between the machine room 18 and the cooler 20 forming the refrigeration cycle, The machine room 18 is installed at the lower rear part of the refrigerator room, and the refrigerator room 20 extends over the rear rear part of the freezing room 4 and the vegetable room 3, and the cooler 20 is installed. And when it is going to increase the storage capacity of both storage rooms, while the partition wall position between the refrigerator room 2 and the vegetable room 3 arranged on the upper part naturally becomes high,
The position of the vegetable drawer door 7 of the vegetable room 3 will be raised. This situation is the same when the cooler 20 shown in FIGS. 9 and 10 is disposed between the machine room 18 and the freezing room 4.

Further, the freezing room 4 having the lowest temperature in the storage room is provided adjacent to the machine room 18 where the temperature becomes high. Since the thickness must be ensured and the depth of the freezing compartment 4 is reduced, the total depth of both the freezing containers 16 and the lower freezing container 15 is required to ensure the required capacity. It is necessary to increase the size, the depth of the upper freezing container 16 and the lower freezing container 15 are both increased, and the container is difficult to take in and out of the stored items. A part of the heat insulating material forming the main body provided between the protrusions 20 protrudes inside the refrigerator.

Along with this, in the refrigerator compartment 2, a convex portion is formed at the back of the lowermost storage portion of the shelf 12 on the main body side, and the depth below the lowermost shelf 12 becomes shallow, which impairs the storageability.

The height of the lower freezer drawer door 10, the upper freezer drawer door 9 and the vegetable drawer door 7 of the vegetable compartment 3 has been increased, and the refrigerating revolving door 6 itself of the refrigerating compartment 2 itself has been increased. As a result, the height dimension is reduced, and the amount of food to be stored in the pocket 11 on the side of the refrigerated revolving door 6 must be reduced. In addition to diversifying the size and type of beverage containers such as bottles, cans, paper packs, and PET bottles, seasonings are also diversifying in container size and type. It is to go against the increase. In the storage section of the shelf 12 on the main body side of the refrigerator compartment 2, the food stored in the back of the uppermost shelf 12 is difficult to reach, and further improvement in usability is required.

In summary, the required capacity of the freezer compartment 4 and the required capacity of the vegetable compartment 3 are secured, the storage capacity of the pocket 11 on the side of the refrigerated revolving door 6 of the refrigerator compartment 2 is secured, and the vegetable compartment 3 is further secured.

Further, the relocation of the machine room eliminates the influence of the compressor, which has been a source of heat, so that it can be dealt with by securing the heat insulation properties at room temperature.
In the vegetable compartment, the cooling unit is moved to the rear rear portion of the freezing compartment, so that the installation position of the cold air amount adjustment damper installed in the portion forming the cold air passage just above the cooling unit is set to the refrigerator compartment. It is necessary to form a convex at the rear rear of the lowermost part of the refrigerator compartment by downsizing from a position straddling the rear rear of the vegetable compartment to the rear rear of the vegetable compartment, and by miniaturizing it into a structure that can be formed in the space in the cool air passage. Has been eliminated, and only the space for securing the cool air passage has been configured, and the bottom integral of the inner box, which is obtained by subtracting the sectional integral of the cool air passage from the sectional integral including the heat insulating material required for the configuration of the cooling unit, has been expanded. Become.

Accordingly, the quotient obtained by dividing the predetermined volume forming the vegetable compartment by the bottom area including the enlarged portion becomes the height of the inner box of the vegetable compartment, and the capacity of the upper vegetable container and the lower vegetable container of the vegetable compartment can be increased. The storage bottom area can be expanded, and the height of the top of the vegetable drawer door in the vegetable room is approximately 1% of the average height of a Japanese adult woman.
This makes it possible to set the vegetable drawer door to a height of 93 cm or less, which is the upper limit value of the vegetable drawer door calculated based on 56 cm.

In the refrigerating room, a compressor or the like forming a machine room is installed on an inconvenient ceiling surface or on an upper rear portion of the refrigerator body. Therefore, the height of the freezer compartment and the vegetable compartment is reduced by the height of the quotient obtained by dividing the volume of the machine compartment by the cross-sectional area of the refrigerator main body with the movement of the machine compartment. Inevitably, the height of the bottom surface forming the inner box of the refrigerator compartment is reduced, and the storage portion of the refrigerator compartment can be configured to have a height that is easier to use as a whole.

Further, the area at the back of the uppermost shelf in the refrigerating compartment, where it is difficult to put stored food in and out, can be made to be a form that can be effectively used as a machine room. Furthermore, since the convex portion formed as the installation portion of the cold air volume adjustment damper at the bottom of the shelf on the main body side of the refrigerator compartment is also eliminated, a highly storable form that can be effectively used to the back of the shelf is adopted. Can be possible.

The storage area of a plurality of pockets provided on the side of the refrigerating revolving door of the refrigerating compartment can be expanded downward by an amount corresponding to the lowering of the partition part constituting the partition wall between the refrigerating compartment and the vegetable compartment. It will also ease the storage of bottles that could not cope with the increase in food and seasonings.
