Problems solved by technology
[0004] However, since the vacuum insulation panel disclosed in JP-A-2002-48466 has micropores in the polyethylene layer of the packaging material of the adsorption member, if a local force is applied to the packaging material during the manufacturing operation of the vacuum insulation panel, then the Japanese paper layer may break
When the Japanese paper layer of its packaging material is broken, there will be the following problems: if the broken part adheres to the sweat and moisture attached to the operator's hands or wrists, or the moisture generated by dew condensation on the device, etc., due to the microscopic Due to the capillary action of the pores, moisture will penetrate into the packaging material, thereby reducing the adsorption performance of the adsorbent

The invention is aimed to keep the handling performance in manufacturing a vacuum heat insulating panel, and the adsorbing performance of an adsorbent for a long period without lowering the productivity, and further to keep superior heat insulating performance for a long period. This refrigerator comprises the vacuum heat insulating panel 1 inside of an outer case 22, and a heat insulating body is constituted by filling a foamed heat insulating material 24 between the outer case 22 and an inner case 22. The vacuum heat insulating panel 1 comprises a core material 3, an adsorbing member 4 and a covering material 2 composed of a gas barrier film and accommodating the core material 4 and the adsorbing member. The adsorbing member 4 comprises an adsorbent 9 for adsorbing at least the moisture, and a wrapping material 5 covering the adsorbent 9, through which the water vapor can penetrate, but the water droplets can not penetrate.
Description
technical field [0001] The present invention relates to a refrigerator and a vacuum insulation panel and a method of manufacturing the same. Background technique [0002] In recent years, from the viewpoint of coping with global warming, the need to reduce power consumption of home appliances has been advocated. In particular, among home appliances, refrigerators consume a lot of electric energy, and it is essential to reduce the electric energy consumption of refrigerators as a countermeasure against global warming. If the load in the refrigerator is constant, most of the electricity consumed by the refrigerator is determined by the efficiency of the cooling compressor in the refrigerator and the insulation performance of the insulation material related to the amount of heat leakage from the refrigerator. Therefore, in the refrigerator technology In development, it is necessary to improve the efficiency of the compressor and the performance of the insulation material. As ...
