First embodiment

As shown in FIGS. 1 and 2, the refrigerator 1 of the present embodiment includes a heat insulating box 3 and a plurality of doors 21 to 26. The front surface of the heat insulating box 3 is formed with an opening, and the inner side is divided into a plurality of spaces. Further, the plurality of doors 21 to 26 seal the openings on the front side of each space. In the following, for convenience of explanation, the side on which the doors 21 to 26 are provided is referred to as the front side, and the side on the inner side of the heat insulating box 3 is referred to as the back side (see FIG. 1).

The heat insulating box 3 includes an inner box, an outer box, and a vacuum heat insulating material 35 as a heat insulating material, and the vacuum heat insulating material 35 is sandwiched between the inner box and the outer box. The vacuum heat insulating material 35 is sandwiched between substantially the entire faces of the facing faces of the inner box and the outer box. Furthermore, in FIG. 2, for the sake of explanation, only the orientation is shown by a broken line.

For the door of the refrigerator 1, a vacuum heat insulating material 35 is also used. The vacuum heat insulating material 35 is formed by vacuuming an inorganic core material such as glass wool by using a laminated film of an aluminum foil and a synthetic resin or a laminated film of a synthetic resin vapor-deposited with aluminum. package. The vacuum heat insulating material formed by such a method has a characteristic that it is difficult to form a thickness strictly in manufacturing, and individual differences occur in thickness. However, the door of the refrigerator 1 must be reliably sealed when it is closed, and for this reason, the distance from the outer panel to the gasket fitting member must be fixed. Therefore, in order to manufacture a door of the same size using a vacuum heat insulating material having an individual difference in thickness, a structure that can absorb the thickness variation of the vacuum heat insulating material is required. Hereinafter, the structure of the door which can respond to the change of the thickness of the vacuum heat insulating material is described.

In order to explain the structure of the door, the second freezing compartment door 26 will be representatively described. As shown in FIGS. 3 to 5, the second freezing compartment door 26 is provided with an outer panel 31, an inner panel 32, a side frame 33, a gasket fitting member 40, a throat member 34, and a vacuum. A heat insulating material 35, a fastener 36, a gasket 37, and a handle 39. In the second freezing compartment door 26, the throat member 34 is integrally formed by being coupled to the inside of the frame of the gasket fitting member 40.

Further, the outer panel 31 of the second freezing compartment door 26 is fixed to the vicinity of the front end portion of the side frame 33. The washer fitting member 40 and the throat member 34 are fixed to the vicinity of the back side end portion of the side frame 33. Further, the inner panel 32 of the second freezing compartment door 26 is disposed on the front side of the throat member 34. The vacuum heat insulating material 35 is disposed between the outer panel 31 and the inner panel 32. The vacuum heat insulating material 35 has a width (size) that occupies substantially the entire opposing surface of the outer panel 31 and the inner panel 32. The washer 37 is fitted to the back side of the gasket fitting member 40. The handle 39 is attached to the front surface of the outer panel 31.

A soft tape 41 is wound around the outer peripheral portion of the vacuum heat insulating material 35.
