Description

  The present invention relates to a refrigerator including a partition member.

  In recent years, there has been an increasing need for bulk purchases and the like for purchasing foods in large quantities at once. Along with this, large-sized refrigerators have become widespread, and as such large-sized refrigerators, doors with double doors divided in the width direction have been adopted as doors for refrigerator compartments. Thus, when the door of a refrigerator compartment is divided | segmented in the width direction, the partition member which obstruct | occludes the clearance gap provided in the boundary of adjacent doors is normally provided in either door. Thereby, it is suppressed that cold air leaks from the clearance gap provided in the boundary of adjacent doors. In addition, since the internal volume of a refrigerator will reduce if the thickness is increased, the partition member is manufactured thinner than the door. For this reason, the heat insulating material provided in the partition member is also thinned, and therefore the heat insulating performance is lower than that of the door. Thereby, a partition member is cooled by the cold inside a refrigerator, and there exists a possibility that a dew may adhere to a partition member.

  For the purpose of suppressing the adhesion of dew to the partition member, Patent Document 1 discloses a refrigerator provided with a rotating partition (partition member) including a dew prevention heater and a thin steel plate that conducts heat. Has been. In this patent document 1, the heat from a dew prevention heater is transmitted to the whole rotary partition by a thin steel plate. Even if the rotating partition is cooled by the cool air inside the refrigerator, this heat suppresses dew from adhering to the rotating partition, and the rotating partition is removed from the gap provided at the boundary between adjacent doors. The cold air is prevented from leaking.

JP 2007-147090 A (page 11, FIG. 5)

  However, in the refrigerator disclosed in Patent Document 1, the rotary partition installed in order to prevent dew is heated by the dew prevention heater, so that the temperature is higher than the temperature inside the refrigerator. . In this high-temperature rotating partition, if the heat transmitted to the thin steel plate of the rotating partition is transmitted not only to the rotating partition but also to the inside of the refrigerator, the temperature inside the refrigerator may increase.

  Moreover, in patent document 1, the flange extended in the direction inside a refrigerator from a thin steel plate is lengthened. Foam insulation such as urethane foam needs to ensure sufficient sealing properties in order to properly foam urethane. In Patent Document 1, the flange inserted in the heat insulating material is lengthened to ensure a sufficient sealing surface. Since this flange extends from the thin steel plate toward the inside of the refrigerator, the heat transmitted through the thin steel plate is easily transmitted to the inside of the refrigerator through this flange. In this case, it is necessary to cool the inside of the refrigerator excessively as the temperature inside the refrigerator rises, and the amount of energy consumption increases accordingly.

  Further, if the width of the thin steel plate is increased in order to improve the thermal conductivity, the heat transmitted in the width direction increases accordingly. Also in this case, it is necessary to excessively cool the inside of the refrigerator as much as the temperature inside the refrigerator rises, and the amount of energy consumption increases accordingly.

  The present invention has been made against the background of the above problems, and provides a refrigerator that suppresses heat generated in a partition member from being transmitted to the inside and suppresses energy consumption required for cooling.

The refrigerator according to the present invention includes a refrigerator main body having at least one storage chamber, a plurality of doors provided on the front surface of the refrigerator main body, closing the storage chamber, and gaps provided at boundaries between adjacent doors. And a partition member that extends along a boundary between doors and extends from a side of a rectangular base having a width that spreads between adjacent doors to both sides of the door to the storage chamber side. A flange portion, and a plurality of engaging portions extending from the end of at least one flange portion toward the door side, a heat conduction member that conducts heat, a heating portion that heats the heat conduction member, and a storage chamber A plurality of engagement receiving portions that are formed on the side surface and engage with the plurality of engagement portions on at least one side in the width direction of the base portion, and are provided closer to the storage chamber than the heat conducting member. The joint and the engagement receiving part engage to conduct heat. And a cover member that covers the heating portion together with the material, the cover member being provided on at least one side in the width direction of the base portion, extending in a direction perpendicular to the direction toward the storage chamber, and projecting to contact the flange portion The cover member is held by the flange portion that has the portion and contacts the protruding portion and the engagement portion that engages with the engagement receiving portion.

  According to this invention, since the engaging part which a heat conductive member has is what extends in the width direction of a base, it is suppressed that the heat which arises in a partition member is transmitted to a storage chamber. For this reason, it is not necessary to cool excessively in the refrigerator, and the required energy consumption can be suppressed accordingly.

Thereby, it is suppressed that the heat conductive member 10 falls from the cover member 30.

  Next, the effect | action of the refrigerator 1 which concerns on this Embodiment 1 is demonstrated. In the refrigerator 1, since the engaging part 14 which the heat conductive member 10 has extends in a direction (arrow X direction) perpendicular to the direction toward the storage chamber 2b, the heat generated in the partition member 5 is stored in the storage chamber 2b. It is suppressed that it is transmitted to. When the heat reaches the storage chamber 2b, the temperature of the storage chamber 2b increases accordingly. And in order to eliminate this, it is necessary to cool excessively by the increased temperature and lower the temperature. In the first embodiment, since heat is suppressed from being transmitted to the storage chamber 2b, it is not necessary to excessively lower the temperature of the storage chamber 2b, so that energy consumption can be suppressed.

  In addition, when the engaging part 14 and the engagement receiving part 31 are provided on both sides in the width direction (arrow X direction) of the partition member 5, the cut-and-raised part 15 extending in the direction toward the storage chamber 2b is omitted. The amount of heat generated in the partition member 5 is further suppressed from being transmitted to the storage chamber 2b.

  Further, when the partition member 5 is assembled, the heat conducting member 10 and the cover member 30 are engaged by merely engaging the engaging portion 14 of the heat conducting member 10 with the engagement receiving portion 31 of the cover member 30. The assembly is easy. Furthermore, the engagement receiving portion 31 of the cover member 30 only needs to be able to engage with the engagement portion 14, and it is not necessary to separately form a claw or the like on the cover member 30, thereby simplifying the structure of the cover member 30. be able to.

  Further, since the engaging portion 14 of the heat conducting member 10 extends in a direction (arrow X direction) perpendicular to the direction toward the storage chamber 2b, the heat insulating material 40 can be insulated without forming the escape portion 41. The material 40 and the engaging part 14 do not contact. As described above, in the first embodiment, since it is not necessary to form the escape portion 41 in the heat insulating material 40 in the portion where the engaging portion 14 is formed, the heat insulating performance of the heat insulating material 40 is improved accordingly. Can be made.
