Title:
REFRIGERATOR
Document Type and Number:
Japanese Patent JP2018025349
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerator which can reduce wall thickness by increasing a vacuum heat insulation material area of a back plate part, without hindering injection properties of a foam heat insulation material and increase in lower storage chamber volume.SOLUTION: A refrigerator includes a refrigerator body 1 having a plurality of storage chambers, and a recess part (upper machine chamber 21) provided at a ceiling part rear side of the refrigerator body 1. A back plate 34 of the refrigeration body 1 is a flat plate shape without a chamfered part and a vacuum heat insulation material 52 is installed. An injection hole 36 of a foam heat insulation material 4 is provided above the vacuum heat insulation material 52 of the back plate 34. Thereby, the foam heat insulation material 4 injected from the injection hole 36 can be filled between inner and outer boxes of the refrigeration body 1 by colliding and dispersing at a bottom surface constitution surface of the recess part without being hindered by the vacuum heat insulation material 52, and wall thickness can be reduced by increasing an attaching area of the vacuum heat insulation material 52 on the back surface portion.SELECTED DRAWING: Figure 2
