Description

  The present invention relates to a refrigerator configuration that prevents heat leakage from a peripheral edge of an opening of a refrigerator, particularly a partition plate that partitions a plurality of storage rooms.

  In recent years, in the refrigerator, in order to reduce power consumption, various technical measures have been studied not only for cooling control but also for a cabinet heat insulating structure. And as a heat leak from a store room, the leak from a clearance seal part with a door in a front opening occupies a big ratio, and as shown in FIG. 57 and 58 are partitioned by a heat insulating partition wall (55), and each front opening is closed by a heat insulating door (57a) (58a).

  A gasket (62) is attached to the peripheral part of each door (57a) (58a), and when the door is closed, the magnet part (62b) of the gasket (62) is provided at the front part of the heat insulating partition wall (55). The gap between the main body of the storage chamber (57) (58) and the door (57a) (58a) is sealed by adsorbing to the front surface of the partition plate (61). Since the magnetic part (62b) is made of a metal plate such as a steel plate to adsorb the magnet part (62b), the temperature inside and outside the storage chamber (57) (58) is heated via the partition plate (61). Conducted and increased the amount of heat leakage.

  In addition, a high-temperature refrigeration cycle pipe (63) is arranged on the back side of the partition plate (61) to prevent the partition plate surface from being cooled by the heat conduction of the cool air in the storage room and dewing below the dew point temperature. However, the heat is conducted to the indoor side through the partition plate (61), which adversely affects the storage room temperature.

  In order to prevent this, conventionally, the folding edge (61a) of the partition plate (61) is covered with a synthetic resin partition cover (65) which is a poor heat conductor to reduce exposure to the room. However, it is difficult to eliminate exposure of the metal partition plate (61) to the indoor side, and because it is in contact with the partition cover (65) located indoors along with this exposed portion, Indoor and outdoor heat leaks could not be avoided.

  In addition, in order to reduce heat conduction to the partition plate (61) as much as possible, a heat insulating sheet (66) made of a soft sponge is affixed to the upper and lower surfaces of the front portion of the partition cover (65) as shown by the two-dot chain line. However, in this configuration, it cannot be said that the structure is suitable as a refrigerator storage room in an environment in which liquid seasonings, beverages, cooking juice, etc. are easily spilled when the storage is taken in and out. Further improvements were required to reduce the power consumption, appearance, and power consumption.

  The present invention has been made in consideration of the above points, and by effectively blocking the heat of the partition plate portion without increasing the cost with a simple configuration, the heat leakage inside and outside the room can be suppressed and the power consumption can be reduced. It aims at providing the refrigerator which can aim at reduction.

  In order to solve the above problems, a refrigerator according to the present invention partitions a plurality of storage rooms formed of heat insulating walls, a door that individually closes the front opening of each storage room, and the adjacent storage rooms. As shown in the figure, the edge of the opening is bent to the indoor side over the width of the opening, and the partition plate made of magnetic metal and arranged in a substantially U-shaped cross section is installed on the peripheral edge of the door. The magnet part consists of a gasket made of a soft resin that seals the gap with the door by adsorbing to the opening periphery of the storage chamber and the partition plate surface, and a partition cover provided so as to cover the indoor side of the partition plate. The partition cover is characterized in that the bent end edge of the partition plate is formed over the entire width from the outside so as to cover it twice by providing a gap.

  According to the refrigerator of the present invention, the indoor and outdoor heat in the partition plate portion is effectively shielded by the gap of the cover portion formed in the partition cover, and the bent edge portion of the partition plate is cooled by the low temperature cold air in the room. In addition, high-temperature external heat can be prevented from entering the room through the partition plate, and power consumption can be reduced.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The refrigerator main body (1) which shows the schematic longitudinal cross-sectional view in FIG. 1 forms the storage space in the inside by the inner box (4) provided through the outer box (2) and the heat insulation layer (3), By dividing the front opening of the storage space by several insulated partitions (5), a plurality of independent spaces are formed in the cabinet, each of which is a refrigerator compartment (6), vegetable compartment (7), ice making Cooling control is performed to a predetermined temperature range suitable for the storage temperature of food such as the room (8) and the freezing room (9).

  The gasket (12) is made by extruding a soft resin so that the attachment part (12a) to the doors (7a) and (8a) and the magnet part (12b) adsorbing to the partition plate (12) can be expanded and contracted. It is formed from the connecting bag-like part (12c), and when the door is closed, the magnet part (12b) is attracted to the opening peripheral edge of the outer box (2) on the storage chamber side and the surface of the partition plate (11). The gap between the door (7a) (8a) and the main body (1) is hermetically sealed, and the inside of the storage chamber (7) (8) and the outside are thermally shut off. And the said partition plate (11) is formed with the metal plate of magnetic bodies, such as a steel plate, for adsorption | suction of a magnet part (12b).

  Moreover, the partition plate (11) is provided over almost the entire width of the storage room, and the edge (11a) in the width direction is bent to the indoor side in order to increase the strength, and a substantially U-shaped cross-sectional shape. It is said. And in the width direction of the back side central part, it is located between the upper and lower magnet parts (12b) of the gasket (12) of the adjacent door, and the high-temperature refrigerant discharged from the compressor of the refrigeration cycle flows. A refrigerant pipe (13) is provided. The refrigerant pipe (13) is arranged over the flange of the outer box (2) at the periphery of the front opening in addition to the respective partition plates, and the partition plate (11 ) And so on to prevent the surface from becoming dewed.

  (15) is a partition cover provided at the front portion of the heat insulating partition wall (5) so as to cover the bent edge (11a) of the partition plate (11). The partition cover (15) extends from the upper and lower ends of the partition wall (5) front partition 15a to the rear step (5a) along the wall surface, and the surface thereof is flush with the upper and lower partition wall surfaces. The front end of the partition plate (11) extends to substantially the same position as the front surface of the partition plate (11), and the bent end edge (11a) of the partition plate (11) is substantially extended from the outer surface side. A space is provided over the entire width so as to cover it twice, forming the bottom surface of the vegetable room (7), which is the upper storage room, and part of the ceiling surface of the lower ice making room (8).

  The gap size of the gap in the double cover (16) provided with the gap may be narrow enough to allow for die cutting, and the depth dimension is a U-shaped bend of the partition plate (11). Extending from the end edge (11a) to the back sufficiently long, and the periphery of the bent end edge (11a) is arranged between the interior side of the partition plate (11) and the front end of the back partition wall (5) The insulating material (17) is covered with the insulating material (17), and the insulating material (17) is overlapped with the double covering portion (16) in the depth direction.

  Further, a soft fin (12d) extending inward from the bag-like portion (12c) at a position spaced apart from the magnet portion (12b) of the gasket (12) toward the indoor side is integrally formed, and when the door is closed, The tip of the soft fin (12d) abuts the tip of the indoor cover (16a) in the double cover (16) of the partition cover (15), and the soft fin (12d) and the magnet ( 12b), an independent seal space is formed.

The soft fin (12d) may not be formed integrally with the gasket (12), but may be integrated with the door inner part or may be a separate sealing part.

  With the above configuration, when the refrigerator is operated, in particular, the partition plate (11) on the ice making chamber (8) side that is the freezing side space is cooled to an extremely low temperature of −18 ° C. or lower. However, due to the presence of the double cover part (16) provided with a gap, the cover part (16b) on the partition plate side has a cover part (16a on the indoor side cooled to a low temperature). ) Is cut off and is hardly conducted, so condensation occurs at low temperature conduction from the bent edge (11a) of the partition plate in contact with the cover (16b) to the front surface of the partition plate (11). This can be suppressed.

  Conversely, heat from the center of the partition plate (11) due to the circulation of the high-temperature refrigerant is also blocked by the air gap and is not conducted to the indoor cover (16a), thereby preventing deterioration of the indoor cooling capacity due to heat leakage. be able to.

  In the above configuration, if the space in the double cover portion (16) of the partition cover (15) is filled with a heat insulator (18) made of a thin-banded soft sponge or the like, two cover portions (16a) ( The heat insulation between 16b) can be further increased, and foreign matter can be prevented from entering the gap.
