Description

  Embodiments of the present invention relate to a refrigerator.

  Conventionally, foamed polyurethane is used as a foaming heat insulating material for heat insulation of refrigerators. However, since the refrigerator housing is required to have higher heat insulation performance, both foamed polyurethane and vacuum heat insulating material may be used. Considering the basic heat insulating performance of the refrigerator housing, the heat insulating performance of the vacuum heat insulating material is approximately 10 times that of polyurethane foam. For this reason, Patent Document 1 proposes a heat insulating wall of the housing that is configured using a vacuum heat insulating material. Here, considering the volumetric efficiency of the housing, the heat insulating wall of the housing composed only of the vacuum heat insulating material can be made thinner than the thickness of the heat insulating wall using foamed polyurethane, A housing having higher volumetric efficiency can be obtained.

JP 2013-2656 A

  However, the technique disclosed in Patent Document 1 has the following problems.

  In the heat insulating wall of the casing made of foamed polyurethane, the foamed polyurethane can be filled between the outer box and the inner box, so that no gap is generated. However, the heat insulating wall of the housing constituted only by the vacuum heat insulating material described above has a gap (space) in the abutting portion between the vacuum heat insulating materials or the protruding portion (fin portion) at the end of the vacuum heat insulating material. Therefore, if the sealing property of the outer box of the housing is not increased, condensation occurs in the gap, and water droplets generated by the condensation may drop on the floor surface of the house.

  In this way, in order to improve the sealing performance of the outer box of the housing, a closed-cell sealant, silicon, or the like is used, the gap between the abutting portions of the vacuum heat insulating materials, or the protruding portion at the end of the vacuum heat insulating material. It is necessary to fill the gap between the fins. For this reason, not only the assembling workability of the refrigerator is deteriorated, but it is also necessary to additionally perform an inspection for ensuring the sealing property, which is a factor that impairs the mass productivity of the refrigerator.

  The present invention has been made in view of the above, and the object of the present invention is that even if the sealing property covering the gap between the vacuum heat insulating materials is incomplete and condensed water is generated, the condensed water is formed as water droplets on the floor. It is in providing the refrigerator which can prevent dripping and falling.

The refrigerator according to the embodiment of the present invention is a refrigerator in which a plurality of vacuum heat insulating materials are disposed between plate members, and is below a space between the vacuum heat insulating material and the adjacent vacuum heat insulating material, A dew receiving portion that receives the dew condensation water generated in the space is provided , and the space position between the vacuum heat insulating material and the adjacent vacuum heat insulating material is at a corner of the refrigerator, and the plurality of plate materials are combined.

Suction pipes 79 are disposed in the internal space of the heat insulating member 77 and in the corner portion CR, or in at least one of them. By arranging the suction pipe 79 in the space in this way, the space can be used effectively. The suction pipe 79 connects the compressor and the cooler, and the refrigerant that has finished its role passes through the suction pipe 79 and returns to the compressor to be compressed again.

  Next, the effect | action of the refrigerator 1 of the structure mentioned above is demonstrated.

  When the refrigerator 1 operates, condensation occurs in the corner portions CR and HS of the main body 2 shown in FIG. As shown in FIG. 12, in the corner portion CR, the vacuum heat insulating materials 50 are abutted against each other, but a space portion without the vacuum heat insulating material 50 is generated. In the space portion of the corner portion CR, for example, as illustrated in FIG. 4, dew condensation occurs and falls in the corner portion CR along the main body 2 along the arrow indicated by a broken line as condensed water W. W can be received by the dew receiving unit 100. Thereby, even if the sealing property which covers the clearance gap between the vacuum heat insulating materials 50 is incomplete, and condensed water W arises and falls through the main body 2, this condensed water W is prevented from dripping and dropping on the floor as water droplets. Can do.

  For example, in FIG. 10, even if the condensed water W falls on the front side of the refrigerator 1, it can be received by the water storage unit 101 of the dew receiving unit 100. In FIG. 4, even when the condensed water W falls in the rear corner portion, the condensed water W can be received by the water storage portions 105 and 106 of the dew receiving portion 100. The condensed water W thus received functions as a reservoir for accumulating the water storage units 101, 102, 103, 104, 105, and 106, and the air AR is dew receiving unit 100 as shown in FIG.
