Description

  The present invention relates to a partition plate of a refrigerator having a plurality of storage rooms, and more particularly to a refrigerator provided with a partition plate that heats a design plate with which a door abuts to prevent condensation.

  A refrigerator having a plurality of storage rooms is provided with a partition plate that partitions the storage chamber, and is made of a magnetic material in which a door-side magnet is magnetically attached to the front (door side) of the partition plate when the door is closed. The designed design board is attached.

  Conventionally, such a design plate has a bent portion obtained by bending an end portion by 90 degrees, and has a substantially U-shaped cross section. The bent portion is directed to the rear (storage chamber side) and attached to the partition plate. The partition plate has a hollow space formed by an outer partition wall and is filled with a foam heat insulating material.

  Here, the front part of the design plate is cooled by the air in the storage chamber using the bent part of the design plate and the partition wall as a heat transfer medium (heat bridge). Then, the temperature of the design plate is lowered below the dew point temperature of the outside air, and dew condensation occurs at the portion where the outside air contacts the design plate. In order to prevent this dew condensation, a heat radiating pipe is attached to the back surface of the design plate, and dew condensation is prevented by keeping the temperature of the design plate at or above the dew point temperature (see Patent Document 1).

JP 2002-364978 A (see paragraphs [0006] to [0007], FIG. 11).

  However, in the configuration of the partition plate in the conventional refrigerator (see Patent Document 1), heat transmitted from the heat radiating pipe to the design plate is transmitted as a heat transfer medium (heat bridge) between the bent portion of the design plate and the partition wall. The heat is dissipated. The heat dissipated into the storage chamber becomes a heat load of the storage chamber, which increases the power consumption of the refrigerator.

  The present invention has been made to solve the above-described problems, and prevents the heat of the heat radiating pipe from entering the storage room side from the bent portion of the design plate by using a simple partition wall structure. The purpose is to suppress electric power.

  The refrigerator according to the present invention is a refrigerator having a plurality of storage chambers partitioned by a partition plate, wherein a gap portion to which a design plate is attached is opened at one end side of the partition plate, and a design plate is disposed in the gap portion. A heat radiating pipe is installed in contact with the partition plate, and the partition plate is provided with a bulging portion formed between the gap portion and the storage chamber and filled with a heat insulating material.

  According to the refrigerator according to the present invention, it is possible to suppress the power consumption of the refrigerator by blocking the heat flow path through which the heat of the heat radiating pipe enters the storage room side from the bent portion of the design plate with a simple partition wall configuration. Become.

The function and effect | action of the refrigerator which concerns on Embodiment 1 comprised in this way are demonstrated.
The first partition plate 12 shown in FIG. 5 will be described as an example.
The design plate 15 includes a bent portion 15b of the design plate 15 and an upper plate 12_1 of the first partition plate 12 due to cold air in the refrigerator compartment 7, the upper freezing chamber 8, and the ice making chamber 9, which are storage rooms adjacent to the first partition plate 12. And the lower plate 12_2 are arranged in an environment that can be cooled using a heat transfer medium (heat bridge).

  In the structure of the 1st partition plate 12 which concerns on this Embodiment 1, the design board 15 is heated with the heat | fever of the heat radiating pipe 20 arrange | positioned at the back side of the design board 15, and the front-surface part 15a of the design board 15 which contact | connects external air has become. Condensation is prevented by keeping it above the dew point temperature of the outside air. At that time, the design plate 15 on the upper freezer compartment 8 or the ice making compartment 9 side having a particularly low internal temperature is provided by providing the lower plate 12_2 of the first partition plate 12 with the expanded portion 26 filled with the foam heat insulating material. It is possible to prevent the heat of the heat radiating pipe 20 from radiating to the respective storage chambers from the bent portion 15b.

In this way, by suppressing the heat radiation from the design plate 15 by the bulging portion 26, dew condensation on the design plate 15 is prevented and the heat from the heat radiating pipe 20 is blocked from entering the storage chamber to reduce the power consumption of the refrigerator. Can be suppressed.
Further, since the bulging portion 26 communicates with the internal space 24 of the first partition plate 12 and the foamed heat insulating material is integrated and filled with the internal space 24, the heat insulating material is disposed separately from the internal space 24. In contrast, it is possible to block heat entering the storage room with a simple configuration.

  In addition, although the example where the bulging part 26 was provided in the lower plate 12_2 in which the internal temperature of the storage chamber adjacent to the first partition plate 12 is low and the heat transfer is large was shown, heat dissipation also exists on the refrigerator compartment 7 side Therefore, by providing a similar bulging portion 26 on the upper plate 12_1 of the first partition plate 12, it is possible to suppress dew condensation on the design plate 15 and heat radiation to the refrigerator compartment 7.

Next, the shape and effect | action when the design plate 15 of the refrigerator which concerns on Embodiment 1 deform | transforms are demonstrated.
6 is a cross-sectional view taken along the line aa showing the shape of the design plate when twisting deformation occurs in the design plate of the refrigerator according to Embodiment 1. FIG.
The hinges 16 and 17 that support the left door 1 or the right door 2 of the refrigerator compartment 7 may be twisted and deformed due to the door load and the stress at the time of opening and closing the door.

The design plate 15 is held by the upper bent portion 15b slidably contacting the lower surface of the upper plate 12_1 and the lower bent portion 15b slidably contacting the upper surface of the bulging portion horizontal surface 12_2c. When the design plate 15 is deformed, the bent portion 15b moves in the direction of coming out of the gap portion 23.

However, the design plate 15 does not slip out of the gap 23 and the inside of the gap 23 is not exposed in the range where the depth length L of the bent portion 15b is larger than the deformation dimension d shown in FIG.
In this way, by inserting the design plate 15 having a U-shaped cross section into the gap portion 23, the design property on the front side of the first partition plate 12 can be secured even if the design plate 15 is deformed, In addition, it is possible to avoid a trouble that the design plate 15 is detached from the gap 23.

  In summary, according to the refrigerator according to the first embodiment, condensation can be prevented by keeping the temperature of the design plate 15 at or above the dew point temperature, and the heat accompanying the rise in the temperature of the design plate 15 causes the design plate 15 to generate heat. Intrusion into the storage chamber via the bent portion 15b can be suppressed and power consumption can be reduced. Even if a stress that causes torsional deformation occurs in the design plate 15, the design property of the design plate 15 can be ensured by sufficiently increasing the depth length L of the bent portion 15 b of the design plate 15.
