Disclosed are a vacuum suction nozzle for improving vacuum suction performance and a vacuum suction apparatus including the same. The nozzle includes blade portions extending from both sides thereof so as to reduce a gap occurring between the nozzle and an outer skin material for a vacuum insulation panel (VIP) or other vacuum wrapping paper when the outer skin material or vacuum wrapping paper is sealed, thereby minimizing the occurrence of a leak and thus enabling efficient vacuum suction. Further, the nozzle achieves efficient vacuum suctioning by ensuring a suction channel inside the vacuum insulation panel (VIP) or other vacuum wrapping paper through a protrusion extending to the front of the nozzle.

Disclosed is a refrigerator including a vacuum insulation panel. The vacuum insulation panel includes a core material, a covering material disposed outside the core material to form an accommodation space in which the core material is accommodated and a first adsorbent disposed in the accommodation space to be activated at a temperature higher than room temperature and to remove at least one of gases and water present in the accommodation space.

Vacuum insulation panel, method of manufacturing vacuum insulation panel, and refrigerator including vacuum insulation panel

A vacuum insulation panel includes a core material, a first sheathing material disposed outside the core material, and a second sheathing material having different thermal conductivity from the first sheathing material, the second sheathing material being coupled to the first sheathing material to form a space to receive the core material.
