  However, when a vacuum heat insulation panel is affixed to the inside (inner surface) of the side surface of the outer box in order to enhance the heat insulation performance, the reinforcement member comes into contact with the vacuum heat insulation panel when the reinforcement member is attached to the outer box. The gas barrier film constituting the surface of the vacuum heat insulating panel is easily damaged, and if it is damaged, the degree of vacuum is destroyed and the heat insulating effect is diminished.

  Then, when attaching a reinforcement member to an outer case, this invention aims to keep this heat insulation effect so that this reinforcement member may not damage the vacuum heat insulation panel stuck on the inner surface of an outer case.

  For this reason, the first invention includes an outer box that is bent inward at the opening edge to form a flange, a reinforcing member that is in contact with the inner surface of the flange and is fixed to the outer box, an inner box, A refrigerator comprising: a foam heat insulating material filled and foamed between a box and the outer box; and a vacuum heat insulating panel disposed between the inner box and the outer box forming a side wall of the refrigerator main body. The upper end portion of the side piece of the reinforcing member extending toward the vacuum heat insulating panel attached to the box is cut off.

  According to a second aspect of the present invention, there is provided an outer box that is bent inward at an opening edge to form a flange, a reinforcing member that is in contact with an inner surface of the flange and is fixed to the outer box, an inner box, and the inner box, In the refrigerator comprising the foam heat insulating material filled and foamed between the outer box and the vacuum heat insulating panel disposed between the inner box and the outer box forming the side wall of the refrigerator main body, the reinforcing member The upper end portion of the side piece in contact with the outer box is cut off.

  According to a third aspect of the present invention, there is provided an outer box that is bent inward at an opening edge to form a flange, a reinforcing member that is in contact with an inner surface of the flange and is fixed to the outer box, an inner box, and the inner box In the refrigerator comprising the foam heat insulating material filled and foamed between the inner box and the outer box, and the vacuum heat insulating panel disposed between the inner box and the outer box forming the side wall of the refrigerator main body, the reinforcing member The upper part of the side piece in contact with the outer box is cut obliquely so that the cut part decreases as it goes downward from the upper end part.

  Further, the fourth invention is an outer case in which a rear flange and a lower flange are formed by bending inwardly at a rear opening edge and a lower end, and a fixed fixing piece abutting on the inner surface of the lower flange and the inner surface of the lower flange. And a reinforcing member having an abutting piece to be in contact with the inner surface of the outer box, an inner box, a foam heat insulating material filled and foamed between the inner box and the outer box, and the side wall forming the refrigerator main body A refrigerator including a vacuum heat insulation panel disposed between an inner box and an outer box, wherein an upper part of an abutting piece that contacts the inner surface of the outer box of the reinforcing member is directed downward from an upper end portion. According to the above, it is characterized in that the cut part is cut obliquely so that the cut part is reduced.

  ADVANTAGE OF THE INVENTION According to this invention, when attaching a reinforcement member to an outer case, this reinforcement member prevents the vacuum insulation panel affixed on the inner surface of an outer case from being damaged, and the refrigerator which can maintain the heat insulation effect can be provided.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS. 1 and 2. 21 is a U-shaped outer box made up of both side plates 21a and a top plate 21b, and a rear flange 22 is formed at the rear opening edge of the outer box 21 by bending inward. Further, the lower flanges 23 are formed by bending the lower ends of the side plates 21a inward.

  A dew-preventing heat radiating pipe 24 is affixed to the inner surface of the outer box 21, that is, near the rear opening edge of the side plates 21a, and to the top plate 21b with a tape 25. Moreover, the vacuum heat insulation panel 26 is each affixed on the inner surface of the both side plates 21a of the outer box 21.

  The bag of the vacuum heat insulating panel 26 has a gas barrier property (high gas barrier property), can be heat sealed, and can accommodate the core material and maintain the inside in a vacuum. That is, this bag is composed of, for example, a gas barrier film, and is composed of, for example, a protective layer for impact reduction from the outside, a gas barrier layer composed of an aluminum-deposited PET (polyethylene terephthalate) layer, a heat-sealed seal layer, Each of these layers is bonded and fixed with an adhesive.

  Reference numeral 30 denotes a reinforcing member for reinforcing the lower portions of the side plates 21a of the outer box 21. The reinforcing member 30 has a rear reinforcing portion 31 and a lower reinforcing portion 32 and has a substantially L shape. Each of the rear reinforcing portions 31 has a substantially L-shaped cross section and is fixed to the rear flange 22 formed by bending inwardly at the rear opening edge of the outer box 21 and fixed via screws 33. 31A and contact pieces 31B that contact the inner surfaces of both side plates 21a of the outer box 21 are provided. Each of the lower reinforcing portions 32 has a substantially L-shaped cross section, and is in contact with a lower flange 23 formed by bending the lower ends of both side plates 21a of the outer box 21 inwardly via screws 33. A fixed piece 32 </ b> A to be fixed and a contact piece 32 </ b> B that comes into contact with the inner surfaces of both side plates 21 a of the outer box 21 are provided.

  Then, a substantially triangular cut portion 31 </ b> C is formed on the upper portion of the contact piece 31 </ b> B that contacts the both side plates 21 a of each rear reinforcing portion 31. That is, the upper part of the contact piece 31B of the reinforcing member 30 extending toward the vacuum heat insulating panel 26 attached to the inner surface of the outer box 21 is cut obliquely so that the cut part decreases as it goes downward from the upper end part. To form.

  When the reinforcing member 30 has a U-shaped cross section, the upper portions of both side pieces extending toward the vacuum heat insulating panel 26 attached to the inner surface of the outer box 21 are directed downward from the upper end portion. It may be formed by being cut obliquely so that the cut portion decreases as it goes.

  Thus, when the reinforcing member 30 is attached to the outer box 21, the reinforcing member 30 is prevented from being damaged to the vacuum heat insulating panel 26 attached to the inner surface of the outer box 21, and the heat insulating effect can be maintained. That is, the abutting pieces 31B of the respective rear reinforcing portions 31 of the reinforcing member 30 are brought into contact with the inner surfaces of both side plates 21a of the outer box 21, and the abutting pieces 32B of the respective lower reinforcing portions 32 are similarly arranged on both side plates of the outer box 21. 21a is brought into contact with the inner surface, and the fixing pieces 31A of the respective rear reinforcing portions 31 are brought into contact with the inner surface of the back flange 22 to be fixed via screws 33, and the fixing pieces 32A of the respective lower reinforcing portions 32 are fixed to the lower flange 23. When abutting on the inner surface and fixing via the screw 33, the reinforcing member 30 is removed by avoiding the vacuum heat insulation panel 26 attached to the inner surface of the outer box 21 by the cut portion 31C formed on the upper portion of the abutting piece 31B. Since it can be fixed to the box 21, the heat insulation effect can be maintained without damaging the vacuum heat insulation panel 26.
