Abstract

PURPOSE:To prevent condensation by raising surface temperature of a laminating fixing frame of an outer plate by providing a door constructed with a heat insulation plate comprising the laminating fixing frame having U-shaped grooves at upper and lower four corners, and an aluminum foil heater around a notched hole in the back of the other plate. CONSTITUTION:An aluminum foil heater 12 is formed with an aluminum foil 13 and a heater cord 14, and stuck to the periphery of a notched hole 5 formed in the back of an outer plate 6. A U-shaped groove 15 is provided in upper and lower portions of a laminating fixing frame 2, into which a cut piece 16 of the outer plate 6 and a cut piece 17 of an inner plate 8 are inserted repeatedly to fix a heat insulation plate 18 comprising a transparent glass 1 and an interval adjusting spacer 3. The refrigerator door formed as above is insulated from heat by a foamed urethane heat insulating material 10 and the heat insulation plate 18. Further, for the heat insulation plate 18 the interior of the refrigerator can be observed through the glass plate 1. Furthermore, for the inner plate 8 and the laminating fixing frame 2 it is inserted and fixed through the U-shaped grooves 15 and hence there is no leakage of the foamed urethane heat insulating material 10.

2. Description of the Related Art Conventionally, as a transparent door body of a refrigerator through which the inside of the refrigerator can be seen, there has been a door body made of a glass plate, as disclosed in Japanese Utility Model Publication No. 47-9724. For example, as shown in FIG. 3, as a conventional general structure, a plurality of transparent glass plates 1 are laminated with a frame 2 for fixing the lamination and a spacer 3 for adjusting the interval, and the laminated transparent glass A plurality of sealed spaces 4 formed between the plates 1 are formed as a heat insulating layer. Then, an outer plate 6 provided with a cutout hole 5 that contacts the lamination fixing frame 2, an inner plate 8 provided with a cutout hole 7 that contacts the transparent glass plate 1, and outer peripheries of the outer plate 6 and the inner plate 8. Decorative frame 9 surrounding
Except for the sealed space 4, it is formed by a foamed urethane heat insulating material 10 filled between the outer panel 6, inner panel 8, and decorative frame 9, and a gasket 11 for sealing the inside of the refrigerator.

Problems to be Solved by the Invention However, in a transparent door body having such a structure, the heat insulation performance of the laminated fixing frame 2 of the door body is lower than that of the foamed urethane heat insulating material 1o.
Since the surface temperature of the stacking and fixing frame 2 is lower than that of the transparent glass plate 1, the surface temperature of the stacking and fixing frame 2 is low, and dew condensation is likely to occur.

In addition, since the inner plate 8 and the lamination fixing frame 2 are poorly fitted, the foamed urethane heat insulating material 10 tends to leak outside, which deteriorates the filling properties in the vicinity of the lamination fixation frame 2, resulting in a partial loss of insulation performance. This caused the dew condensation mentioned above to increase.
