2. Description of the Related Art FIG. 4 is a sectional view showing a main part of a conventional refrigerator near a contact portion between upper and lower doors and a partition wall.

The front part (21) of a partition wall (6) for partitioning each storage room
In order to prevent perspiration caused by a temperature difference between the outside air temperature and the inside temperature, a part of a heat radiating pipe (26) of a cooling device (not shown) is partially connected to a partition wall near a contact portion with a door. By arranging in (6), sweating was prevented.

A contact plate (35) is provided on the front part (21) of the partition wall (6).
The heat radiating pipes (26) are arranged in two vertical stages in a U-turn on the back side of the contact plate (35).

However, when the heat radiating pipe (26) is bent by making a U-turn, the radius of the bent portion is increased to prevent the pipe from being deformed, and the interval between the heat radiating pipes (26) is increased. Since the two-stage radiating pipes (26) with a large space are arranged behind the U-shaped contact plate (35), the height of the contact plate (35) is increased, and There was a problem that the thickness (height dimension) of the partition wall (6) to which the (35) was attached also became large, and the internal volume of the compartment became small.

Further, since the heat radiating pipes (26) are arranged in two stages, the area of the front surface (21) of the partition wall (6) becomes large due to the heat radiating pipes (26) having a large space therebetween. At the same time, the gap between the upper and lower doors widened, and the contact area with the outside air increased. For this reason, the influence of heat on the inside of the refrigerator via the contact portion has increased, which has been a hindrance to energy saving.

Therefore, a refrigerator in which a heat radiation pipe is provided near the upper and lower centers of the partition wall has been proposed (see HFA99-0133 filed by the present applicant on the same date).

FIG. 1 is a perspective view of a refrigerator according to this embodiment, with a portion cut away.

The main body (2) of the refrigerator (1) is composed of an outer box (3), an inner box (4), and a heat insulating material (5) such as polyurethane foam filled between the two boxes.

The main body (2) is divided into four upper and lower compartments by a partition wall (6, 6,...) Which vertically divides a heat-insulating box that opens forward, and storage rooms (7, 8, 9, 10) are formed. Have been.

The opening (7a, 8a, 9a, 10) of the front of the refrigerator body (2)
a) is provided with doors (14, 15, 16, 17) that are openably and closably sealed corresponding to the storage rooms (7, 8, 9, 10).

FIG. 2 is a sectional view taken along line AA of FIG.

In FIG. 2, the partition wall (6) of the refrigerator body (2)
The doors (15, 16) are in close contact with the front surface (21c).

The partition wall (6) comprises a front surface (21c), an upper surface (22) and a lower surface.
And (23) are continuously formed integrally with a synthetic resin material having a low thermal conductivity so as to form an interior surface of the inside of the refrigerator, and the inside is filled with a heat insulating material (5 ′) such as foamed polyurethane.

On the front surface (21c) of the partition wall (6), protrusions (19a, 19b) having the same height are formed at the upper and lower portions over the entire width, and the upper and lower protrusions (19a, 19b) are formed. Accordingly, a concave groove (24) is formed in the center of the front surface (21C) over the entire width of the partition wall (6).

A U-shaped metal contact plate (25) which is attracted to the magnet is attached so as to cover the groove (24), and the metal contact plate (25) is attached to the partition wall (6). And has a height dimension that is at least twice the height of each of the upper and lower projections (19a, 19b), and comes into contact with the back side of this contact plate (25) to form the groove (24). A part of a heat dissipation pipe (26) for preventing perspiration is piped in the center of ().

FIG. 3 is a partially enlarged view of FIG.

Door gaskets (27a, 27b) having the same cross-sectional shape are attached to the upper and lower doors (15, 16) all around.

These door gaskets (27a, 27b) are provided with mounting hooks (28, 28) and a plurality of cavities (31, 31,...) Having cavities formed of an elastically deformable material such as rubber or synthetic resin. )
And a plurality of fins (32, 32, ...) formed on the end face of the hollow portion (31, ...) and in contact with the inner surface of the door (15) or the door (16), One of the cavities (31) is provided with a magnet section (33) that contains a magnet inside the cavity. The door gaskets (27a, 27b) are fixed to the doors (15, 16) by inserting mounting hooks (28) into mounting holes (29) formed in the doors (15, 16).

Further, a fin (32) integrally formed over the entire width of the door is provided at the lower end of the door gasket (27a) of the upper door (15).
a) (hereinafter referred to as lower polymerization fin), and a fin (32b) (hereinafter referred to as upper polymerization fin) integrally formed over the entire width of the door is provided at the upper end of the door gasket (27b) of the lower door (16). It overlaps when the upper and lower doors (15, 16) are closed.

When the upper and lower polymerization fins (32a, 32b) overlap, air in the space formed by the gap (S) between the upper and lower doors (15, 16) flows to the front surface (21c) of the partition wall (6). We shut off so as not to touch.

That is, the lower fin (32b) of the upper door (15) is extended downward, and the upper fin (32a) of the lower door (16) is extended.
Are extended upward, and the ends of both polymerization fins (32a, 32b) are in contact with the ends of the door gaskets (27b, 27a) of the doors adjacent to each other, and overlap each other.

Thus, the front surface (21c) of the partition wall (6) is cut off from the space in front of the partition wall (6c). The length of these upper and lower fins (32a, 32b) is the length of the adjacent door (15, 1).
It is about 2/3 of the vertical dimension between 6).

In the refrigerator (1) thus constructed, by closing the doors (15, 16), the door gasket (27) is closed.
a, 27b) and the contact plate (25) on the front surface of the partition wall (6) are attracted to the door gasket (27a) attached to the entire periphery of the door (15, 16). , 27b) are in contact with the front surface (21c) of the partition wall (6), and the doors (15, 16) and the contact surface of the partition wall (6) are more airtightly sealed.

Further, by providing the upper and lower polymerization fins (32a, 32b), the air flowing through the gap (S) between the adjacent doors (15, 16) is blocked from the front surface (21c) of the partition wall (6). The partition wall
In addition to reducing the influence of outside heat on the front surface (21c) of (6) and reducing the intrusion of outside heat conducted through the contact plate (25), the outside air and outside air It is possible to reduce sweating caused by a temperature difference from cold air in the inside.

Further, since the contact plate (25) has good thermal conductivity,
The height of the front part (21) of the partition wall (6) is reduced to not more than two-thirds of the height of the partition wall (6) instead of the full width, and the resin upper and lower protrusions with low thermal conductivity ( 19a, 19b), and is suppressed to about twice the height dimension. As a result, the area of the contact plate (25) is reduced, and the amount of external heat received by the contact plate (25) is reduced, and the external heat received by the contact plate (25) is reduced by the vertical protrusions (19a, 19a).
Blocked by b), making it difficult to transfer heat into the chamber. Similarly, it is difficult to transmit cold air inside the refrigerator to the outside of the refrigerator.

Thus, the occurrence of perspiration can be reduced, and the amount of heat for preventing perspiration can also be reduced.

According to the present invention, the polymerization fin (32
a, 32b) may be a tube having a bag-like cross section. By forming the tube into a bag-like shape, an air heat-insulating layer is provided inside the tube so that the heat insulating effect can be enhanced.

The magnets (34) may be in the form of continuous strips, or may be provided at predetermined intervals.

In the first embodiment, the door gaskets (27a, 27b) are attached to the adjacent upper and lower doors (15, 16) over the entire circumference, respectively.
a, 27b) has a built-in magnet in one of the plurality of cavities (31), and a front part (21) of the partition wall (6).
Was provided with a contact plate (25).

By providing the upper and lower overlapping fins (32a, 32b) on the adjacent upper and lower doors (15, 16),
Sealability between the inside and outside of the refrigerator is improved.

Therefore, the magnet in the door gasket (27a, 27b) can be eliminated.

Therefore, according to the present application, the adjacent upper and lower doors
It becomes possible to abolish the (15,16) magnet. By doing so, the cost can be reduced and the recyclability of the door gaskets (27a, 27b) is improved.

By eliminating the magnets of the upper and lower doors adjacent to each other, the contact plate can be made of resin instead of metal. The heat conduction between the outside air and the cold air in the refrigerator can be suppressed to reduce the occurrence of perspiration, and the influence of the heat outside the refrigerator on the refrigerator can be reduced.

In addition, since the magnet prevents deformation of the door gasket, the door gasket is deformed when the magnet is abolished, and a gap with the main body when the door is closed due to this deformation is likely to cause cold air leakage.

For this reason, a deformation member for preventing deformation of the door gasket may be inserted by inserting a reinforcing material for preventing deformation or a heat-insulating cushioning material into a portion where the magnet is conventionally inserted.

Further, only one of the magnets of the adjacent upper and lower doors can be eliminated. In that case, the magnet in the room with a high temperature zone (the refrigerator room if the upper and lower sides are a freezer room and a refrigerator room) is eliminated.

Also, In the present embodiment, the partition wall that separates the second and third stages is described, but the same configuration is applied to other partition walls. Further, the door may be a one-sided opening / closing door or a drawer-type door.

[0051]

As described above, according to the present invention, the overlapped fins that overlap each other when the doors are closed are provided in the adjacent doors so that they flow into the gaps between the adjacent doors. Since the outside air is cut off from the front of the partition wall, the influence of heat outside the store on the front of the partition wall can be reduced, and sweating caused by the temperature difference between the air outside the store and the cool air in the store can be reduced. .

Also, since the amount of perspiration generated can be reduced, the amount of heat for preventing perspiration can be reduced, so that the heat influence on the inside of the refrigerator is reduced and the energy saving effect is enhanced.
