2. Description of the Related Art In a conventional refrigerator, a plurality of storage compartments suitable for the temperature of each food are formed by partitioning the inside of a refrigerator formed by foaming and filling a heat insulating material between an outer box and an inner box at a plurality of temperature zones. Provided.
Conventionally, a refrigerator room is provided at the upper part, a refrigerator room is provided at the center, and a vegetable room is provided at the lower part, but in recent years, refrigerators having various layouts have been proposed.

For example, Japanese Patent Laid-Open No. Hei 5-223431 proposes a refrigerator called a mid freezer in which a freezing room is arranged in the center. The concrete structure is as follows: a refrigerator room with an opening / closing door at the top of the refrigerator, a freezing room with a drawer door arranged in two stages at the center, and a vegetable room with a drawer door at the bottom A compressor is arranged at the rear of the vegetable compartment, and a fan motor and a heat exchanger are arranged at the rear of the freezing compartment.

[0004] For example, in Japanese Patent Application Laid-Open No. 5-60440, a refrigerator is provided with an opening / closing door through a partition wall.
The upper storage room is a refrigerator room with a drawer-type vegetable room at the bottom, and the lower storage room is a freezer room with a plurality of drawers.

[0005] For example, Hitachi, Ltd. has a refrigerator room with an opening / closing door at the top of a refrigerator, a vegetable room / refrigeration room (switching type) with an opening / closing door with a rotating storage case at the center, and a rotating bottom at the bottom. Refrigerator to be a refrigerator with a vegetable storage case and an open / close door with an ice-making shelf was remodeled in 1980 as model R-336BR.
It is sold as V.

[0006] For example, Japanese Utility Model Publication No. 37-18668 discloses a multi-purpose storage room having a drawer door located at the center or waist of a refrigerator, provided with a storage room having upper and lower opening doors. A refrigerator is disclosed.

[0007]

Investigation into the actual use of refrigerators reveals that refrigerators are installed side by side with kitchen sinks, and are frequently used when cooking in a standing posture. The frequency of use is followed by the refrigerator compartment, then the vegetable compartment, then the freezer compartment. In view of the actual use in this standing posture, it can be said that the refrigerator compartment at the top, the vegetable compartment at the center, and the freezer compartment at the bottom match the actual use.

However, for example, in the above-described conventional example, although the usability of the refrigerator compartment is improved, since the vegetable compartment is arranged below the freezer compartment, the vegetable compartment must be used in a crouching posture. There was a problem in the usability of the vegetable room. In particular, since the freshness of vegetables quickly deteriorates, placing a vegetable room, which must be constantly monitored for freshness, below a freezer room for long-term storage of frozen foods improves from the viewpoint of actual use. It was a task to be done.

On the other hand, for example, in the above-mentioned conventional example,
Although the vegetable room is located in the center, the positional usability is improved. However, in view of the implementation of this type, the vegetable room is located at a high position of 1000 mm or more. There is a problem in coordinating with the work in Tokyo and taking in and out of large vegetables.

Further, for example, in the above-mentioned conventional example,
Since the vegetable compartment is located in the refrigerator compartment, the door and drawer must always be opened and closed when using the vegetable compartment. Therefore, there is a problem that the drawer is damaged when the opening / closing door is closed with the drawer pulled out.

For example, in the above-described conventional example, a vegetable room can be made by switching the central storage room, but this vegetable room / refrigerator is further provided with an openable storage case inside the openable door. Therefore, two opening and closing operations are always required for use. Moreover, in this conventional example, since the opening / closing door and the rotary storage case are opened and closed by one hinge, the center of gravity moves diagonally forward, and there is a problem in the sense of stability of the main body.
Further, in this conventional example, since all the storage rooms are opened and closed, there is a problem in the usability of the storage rooms arranged below.

[0012] For example, in the above-mentioned conventional example,
Although the structure of the central storage room is disclosed, there is no specific disclosure of the upper and lower storage rooms. Furthermore, there is no specific disclosure of a refrigerator related to the temperature inside the storage room. In addition, since the lowermost storage room is an opening / closing door, there is a problem in usability of the lower storage room in a squatting posture.

[0013] An object of the present invention is to provide a refrigerator in which the ease of use of the vegetable compartment is improved.

Next, referring to FIG. 8 to FIG.
00, vegetable room 200 and freezer room 800 (upper freezer room 300
And the convenience associated with the arrangement of the lower freezing compartment 400). FIG. 8 is an installation state diagram of the refrigerator 1, and FIG. 9 is an explanatory diagram showing a relationship between a human system and an arrangement of a storage room of the refrigerator 1.
0 is an explanatory diagram showing the use frequency of the storage room.

In FIG. 8, when considering the usability of the refrigerator 1, it is necessary to consider the installation environment and the system of the person who uses the refrigerator. That is, since the refrigerator 1 is installed in the kitchen, it is necessary to consider the relationship between the sink 700, the cupboard, and the like, which are often used side by side in the kitchen, and the household equipment. In particular, the refrigerator 1 and the sink 700 are important because they are frequently used as a part of cooking. And, as a matter of course, the part work flow must be adapted to the system of the person who uses it. The refrigerator 1 according to the present embodiment is planned from the above viewpoint.

For example, a standard Japanese woman (height 15)
When the refrigerator 1 is 400 mm away from the refrigerator 1 and the refrigerator 1 is used, the range Y2 that can be easily reached while standing is 630 below.
mm, the upper part is 1340 mm. Above 1340 mm is the storage range Y1 above the shoulder. Further, the storage range Y3 in which the bent position is set is 310 mm below and 630 above.
mm. The lower part of 310 mm is a storage range Y3 in which the squatting posture is set. The standard female elbow height is 970 mm, and food can be easily taken in and out without raising the elbow below this position. Considering the workability of the refrigerator 1 from these points, the height of the elbow is 970.
In the storage room arranged above from mm, the work operation in the standing posture with the opening and closing door 10 is good. On the other hand, elbow height is 97
Below 0 mm, drawer doors 20, 30, 4 that can take in and out food while looking at the storage room in any posture
0 is excellent in workability. In particular, in consideration of the workability in the standing posture, since the height that can be reached by humans is 643 mm, the drawer door 20 arranged at the upper stage below the height of the elbow 970 mm is the floor of the drawer door 20. Surface height is 64
If it is 3 mm or more, the food can be taken in and out in a standing posture and in a comfortable posture. The height of the floor surface of the drawer door 20 is set lower if the posture is such that the posture can be easily changed from the standing posture to the crouching posture. That is, if a drawer door is provided at a position lower than the height of the elbow and within reach of the standing posture and the crouching posture, food can be easily taken in and out. The dimensional relationship described above is a numerical value based on a standard female model, and its numerical range is, for example, considering the height of slippers usually worn in a kitchen, a user's coverage, a storage capacity, and the like. Other conditions need to be considered.

Referring to FIGS. 9 and 10, when the actual use of the refrigerator is investigated, the refrigerator 1 is installed side by side with the kitchen sink 700, and is frequently used for cooking in a standing posture. The frequency of use is refrigeration room 100, then vegetable room 200,
Next, the freezing room 800 (the upper freezing room 300 and the lower freezing room 40
0).
