2. Description of the Related Art In a conventional refrigerator, the inside of a refrigerator formed by foaming and filling a heat insulating material between an outer box and an inner box is divided into a plurality of temperature zones to form a plurality of storage rooms suitable for each food temperature. 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 Publication No. Hei 5-223431 (referred to as a first conventional example) 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 Laid-Open Publication No. Hei 5-60440 (hereinafter referred to as a second conventional example), a refrigerator is divided into two storage rooms provided with opening and closing doors through a partition wall, and an upper storage room is arranged at the most. A refrigerator room with a drawer-type vegetable room at the bottom,
The lower storage compartment is a freezer compartment with multiple drawers.

[0005] For example, Hitachi, Ltd. has a refrigerator compartment with an opening / closing door at the top of a refrigerator, a vegetable compartment / refrigeration compartment (switching type) with an opening / closing door with a rotating storage case at the center, and a bottom. Refrigerator with a refrigerating room equipped with a rotating vegetable storage case and an opening / closing door with an ice making shelf
It is sold as 336BRV (referred to as a third conventional example).

[0006] For example, in Japanese Utility Model Publication No. 37-18668 (hereinafter referred to as a fourth conventional example), a storage room having upper and lower opening doors is provided, and a drawer door is provided at the center or waist of the refrigerator. A refrigerator with a multipurpose storage compartment is disclosed.

SUMMARY OF THE INVENTION It is a first object of the present invention to provide a freezing compartment comprising an upper freezing compartment and a lower freezing compartment, and by arranging an ice making section and a heat exchanger so as to make the freezing compartment easier to use. And to improve the refrigeration efficiency. A second object of the present invention is to improve the depth of the storage cases of the upper freezer compartment and the lower freezer compartment and the arrangement of the compressor to improve the ease of use of the freezer compartment and to improve the mounting efficiency.

However, in the first conventional example, for example, although the usability of the refrigerator compartment is improved, since the vegetable compartment is arranged below the freezer compartment which is not frequently used, the vegetable compartment is used in a crouching posture. It must be said that the vegetable room is inconvenient. In particular, given that the freshness of vegetables quickly deteriorates, placing a vegetable room, where freshness must be constantly monitored, below a freezer room that stores frozen foods for a long period of time does not fit the actual usage. is there.

Further, it is known that freshness of vegetables is remarkably reduced when they are piled up vertically or an unnecessary force is applied. In the first conventional example, a compressor is provided behind the vegetable compartment. Therefore, there is a problem that the back of the vegetable room becomes oblique, and the vegetables stored on this slope push other vegetables to reduce freshness. Furthermore, in the said 1st prior art example, since the freezer compartment whose inside temperature differs greatly from a refrigerator compartment and a vegetable compartment is arrange | positioned between a refrigerator compartment and a vegetable compartment, heat insulation material is provided above and below a freezer compartment. Must be provided.

[0010] Further, since the freezing compartment is arranged above the vegetable compartment, the heat exchanger and the fan motor which are arranged to accompany the freezing compartment are necessarily arranged above, and the compressor and the heat exchanger are connected to each other. Not only is a dead space formed between them, but the center of gravity shifts upward and the stability of the refrigerator itself deteriorates.

On the other hand, for example, in the second and third conventional examples, the vegetable room is arranged at the center, so that the positional convenience of the first conventional example is improved, but this type of implementation is not required. In view of the situation, since the vegetable room is arranged at a high position of 1000 mm or more, there is a problem in cooperating with the operation in the sink and taking in and out of large vegetables.

Further, for example, in the second conventional example, since the vegetable compartment is arranged in the refrigerator compartment, the openable door and drawer must always be opened and closed when the vegetable compartment is used. In addition, there is a problem of lowering the temperature in the refrigerator and damage when the opening / closing door is closed with the drawer pulled out.

For example, in the third conventional example, a vegetable room can be made by switching the central storage room. This vegetable room / refrigerator is further provided with an openable storage case inside the openable door. Use, always use 2
Two opening and closing operations are required. Moreover, in this conventional example,
Since the opening and closing door and the rotating storage case are opened and closed by one hinge, the center of gravity moves obliquely forward, and there is a problem that the stability of the main body is deteriorated. 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.

For example, in the fourth 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.

A first object of the present invention is to provide a refrigerator that is easy to use by arranging a refrigerator compartment, a vegetable compartment, and a freezer compartment one above the other in the order of frequency of use.

A second object of the present invention is to provide a refrigerator in which the vegetable compartment is arranged in a door region suitable for a bent posture and the vegetable compartment is arranged in an operation area most suitable for this posture.

A third object of the present invention is to provide a refrigerator having a low center of gravity and an efficient storage space with reduced dead space.

A fourth object of the present invention is to provide a refrigerator having a low center of gravity and a good storage capacity of a vegetable room.

A fifth object of the present invention is to provide a refrigerator having a high freezing efficiency in a freezing room.

[0020]

In order to achieve the above object, the present invention employs the following configuration.

According to the first aspect of the present invention, a refrigerator compartment is provided above the refrigerator, a freezer compartment is provided below the refrigerator, and a vegetable compartment is provided independently between the refrigerator compartment and the freezer compartment.

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, FIG. 9 is an explanatory diagram showing the frequency of use of each storage room of the refrigerator, and FIG. 10 is an explanatory diagram showing a relationship between a posture of a human and an arrangement of each storage room of the refrigerator 1. .

In FIG. 8, when considering the usability of the refrigerator 1, it is necessary to consider the installation environment and the usage pattern of a person who uses the refrigerator. In other words, since the refrigerator 1 is installed in the kitchen, it is often used side by side in the kitchen.
0 (see FIG. 10) and the relationship between cupboards and other housing equipment must be considered.

In particular, the relationship between the refrigerator 1 and the sink 700 is important because it is frequently used as part of cooking. And, as a matter of course, the flow of the partial work must be adapted to the usage pattern 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 in the standing posture is 6
30 mm, 1340 mm above. Above 1340 mm is the storage range Y1 above the shoulder. Further, the storage range Y3 that can be easily reached when the person is in the crouching posture is 3
10 mm, 630 mm above. And 310m
Below m is a storage range Y3 that can be easily reached when the squatting posture is attained.

The standard female elbow height is 970 m.
m, and the food can be easily taken in and out without raising the elbow if it is below this position.

In view of these points, in view of the workability of the refrigerator 1, in the storage room arranged above the elbow height of 970 mm, the work operation in the standing posture with the opening / closing door 10 is good. On the other hand, when the height of the elbow is below 970 mm, the workability of the drawer doors 20, 30, and 40 that can take in and out food while looking over the storage room is excellent in any posture.

In particular, in consideration of the workability in the standing posture, the height of the lower side which can be reached by a standard Japanese woman is 643.
mm, the drawer door 20 arranged below the height of the elbow 970 mm, if the height of the drawer door 20 from the floor surface is 643 mm or more, in a standing posture to put food in and out in a comfortable posture. It can be carried out. The height of the drawer door 20 from the floor surface 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 the 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 above dimensional relationship is a numerical value based on a standard female model, and the numerical range is, for example, considering the height of slippers usually worn in a kitchen,
It is necessary to consider other conditions such as the user's coverage and storage capacity.

According to an investigation of the actual use of the refrigerator, as shown in FIG. 10, the refrigerator 1 is installed side by side with the kitchen sink 700, and is frequently used when cooking in a standing posture.
As shown in FIG. 9, the frequency of use is as follows: refrigeration room 100, then vegetable room 200, then freezer room 800 (upper freezer room 300
And the lower freezer compartment 400). According to the actual usage in this standing position, the refrigerator compartment 100 is located at the top, and the vegetable compartment 20 is located at the center.
0. By arranging the freezing compartment 800 (the upper freezing compartment 300 and the lower freezing compartment 400) below, the operation of shifting from the standing posture to the crouching posture and the crouching posture can be reduced, and the work operation can be facilitated.

On the other hand, considering the housing environment of the kitchen, the lower part of the hanging cabinet of a general kitchen is 1800 mm. Is only required to be 1800 mm or less.

On the other hand, a sink 700 adjacent to the refrigerator 1
Has a height to a table (cooking table) of 850 mm and a height to a faucet 702 of about 870 mm. Therefore, in the standing posture or the slouching posture in which the posture can be easily changed from the standing posture, the elbow height is set at 970 mm as a reference, and the frequently used storage room is arranged within the above-mentioned operation range, so that the current can be changed. The work on the table 700 and the work on the refrigerator 1 can be smoothly and comfortably performed as a series of work without greatly changing the posture.

Now, in the refrigerator 1 according to the present embodiment, the arrangement of the storage rooms is changed according to the order of use frequency.
Refrigeration room 100, vegetable room 200, freezer room 8 from top to bottom
00, and furthermore, the freezing room 800 is divided into two, and the upper freezing room 300, which is frequently used, is located at the upper part, and the lower freezing room 400, which is used less frequently, for storing stock foods is located at the lower part. The moving operation from the standing posture to each posture can be efficiently reduced in accordance with the frequency of use.

The upper door is referred to as the opening / closing door 10 based on the height of the elbow, and the door lower than the height of the elbow is referred to as the drawer door 2.
Since they are 0, 30, and 40, the door structure of each storage room is structured to match the operating posture.
