Abstract: 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.

Abstract: 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.

Abstract: Disclosed are a vacuum insulation material having a structure from which a folding process can be removed, a vacuum insulation material manufacturing method, and a refrigerator including the vacuum insulation material. The vacuum insulation material comprises: a core material; a first outer cover material disposed at the outside of the core material; a second outer cover material coupled to the first outer cover material so as to form an accommodation space in which the compressed core material is accommodated; and coupling parts provided at edges of the first outer cover material and the second outer cover material, wherein the length of the coupling part is 10-30 mm.

Abstract: Disclosed are a vacuum insulating material having an improved structure as to enhance insulation and durability and a refrigerator having the same. The vacuum insulating material includes a core material, a first envelope disposed at an outer side of the core material, a blocking layer disposed between the core material and the first envelope, and a second envelope coupling to the first envelope to form an accommodating space in which the core material and the blocking layer are accommodated, wherein the blocking layer is welded or adhered to the first envelope to form an integral unit with the first envelope.

Abstract: 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.
