Description

An embodiment of the present invention relates to a refrigerator.

In refrigerators where dew-proof pipes are installed around the outer periphery of the side panels of the main body to prevent condensation, when filling the main body with foam insulation, the foam insulation may leak from the connections between each partition and the side panels due to the dew-proof pipes floating against the side panels. To prevent leakage, the dew-proof pipe is fixed to the side plate using a fixing means such as tape. Furthermore, a notch is provided partially in the reinforcing portion of the side plate in order to ensure a passage for the dew-proof pipe of the side plate to extend through the partition. In the method of fixing the dew-proof pipe using a fixing means, there are many variations in the fixing state, and it is difficult to stably fix the dew-proof pipe. Therefore, there is a need for a refrigerator that has a side plate with a notch that has increased rigidity and that does not cause the foam insulation to leak from the gap in the notch leading to the partition due to floating of the anti-condensation pipe during filling with the foam insulation. Ta.

It is. The core material is, for example, a fibrous material such as glass wool or a porous material such as foam. Furthermore, instead of the vacuum heat insulating material, it is also possible to employ a specific heat insulating material containing one or more of airgel, xerogel, or cryogel.

Next, the operation of refrigerator 1 will be explained.

The refrigerator 1 according to this embodiment has a main body 10 that forms a storage chamber 11, and a door that can be opened and closed to cover the opening of the main body 10. It also has partitions 15, 16 that extend in the width direction within the storage chamber 11 and divide the storage chamber 11 into an upper storage chamber and a lower storage chamber, a reinforcing part 121 that reinforces the opening side of the side plate 12 of the main body 10 in the vertical direction, and a dew prevention pipe 65 arranged on the side plate 12 and the partitions 15, 16. The reinforcing part 121 has a notch 122 at the connection part with the partitions 15, 16. A pipe fixing part 70 that fixes the dew prevention pipe 65 at the connection part between the side plate 12 and the partitions 15, 16 is attached to the side plate 12.

In this embodiment, the pipe fixing component 70 to which the dew-proof pipe 65 is fixed at the connecting portion between the side plate 12 and the partitions 15 and 16 is assembled to the side plate 12 on which the reinforcing part 121 is formed. It can be securely fixed in a predetermined position. Therefore, when manufacturing the refrigerator 1, the foamed heat insulating material 10k, such as urethane, can be reliably filled between the inner box 10i and the side plate 12, and a decrease in the rigidity of the side plate 12, which is the main body 10, can be suppressed. When the foamed heat insulating material 10k is filled, it is possible to prevent the dew prevention pipe 65 and the side plate 12 from floating, and to prevent the foamed heat insulating material 10k from leaking out from the notch 122. In addition, in this embodiment, by using the pipe fixing component 70, the fixing state of the dew-proof pipe 65 will vary, unlike when fixing the dew-proof pipe 65 using a fixing means such as tape, and it will not be stable. It is possible to prevent the foamed heat insulating material from leaking out from the gap between the partitions 15 and 16 due to floating of the side plate 12 during manufacturing due to the foamed heat insulating material being unable to be fixed. Moreover, since the foamed heat insulating material is no longer filled in the areas where a large amount of tape is used as in the past, it is possible to prevent the rigidity of the side plate 12 from partially decreasing.
