[0007]
Function and effect of the present invention
<Invention of claim 1>
The cold heat in the refrigerator may be transmitted to the frame through the transparent plate and the spacer that constitute the multilayer transparent plate, but an interposer with low thermal conductivity is placed between the transparent plate and the spacer. Since it is mounted, conduction of cold heat is suppressed thereby, and cooling of the frame body is also suppressed. Therefore, it is possible to prevent dew condensation from occurring on the surface of the frame. Accordingly, it is not necessary to equip the frame with a dew condensation prevention heater, so that the structure is simplified and power can be saved.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment in which the present invention is applied to a refrigerated showcase will be described with reference to the accompanying drawings.
<First embodiment>
A first embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the refrigerated showcase of this embodiment includes a case main body 10 formed of a vertically long heat-insulating box with an open front surface, and is supported by legs 11 provided on the bottom surface. The interior of the case body 10 is a storage room, and four openings 13 (see FIG. 5) are formed in the front of the storage room by partitioning the storage room. 15 is mounted in a double-opening manner via a hinge 16. Then, while opening and closing the door 15 with the handle 17, cold beverage cans such as juice and beer are put in and out of the storage room.
[0010]
Subsequently, the structure of the door 15 will be described. As shown in FIGS. 2 and 3, the door 15 roughly includes a frame 20, a handle 17, and a double glazing 30 fitted in the frame 20.
The frame body 20 further includes two vertical frames 21A and two horizontal frames 21B. The vertical frame 21A and the horizontal frame 21B are formed, for example, by extruding an aluminum material into a substantially rectangular tube shape as shown in FIG. 5, and cut to a predetermined length while forming both ends at 45 degrees. Have been. At the position near the inner surface of each of the frames 21A and 21B, a fitting groove 22 for the double glazing 30 is formed, and at the back of each of the frames 21A and 21B, a mounting groove 24 for the magnet packing 23 is formed. Have been. A channel-shaped reinforcing member 25 is inserted into each of the frames 21A and 21B.
Further, a handle 17 is attached to the surface of one vertical frame 21A.
[0011]
The double-glazed glass 30 includes two transparent glass plates 31, and the two glass plates 31 are integrally joined at a predetermined interval by sandwiching a spacer 33 or the like between peripheral portions. The spacer 33 contains a desiccant, and as shown in detail in FIG. 6, a desiccant 36 is filled in a metal spacer 34 formed in a rectangular cylindrical shape by extrusion molding, and the inner surface of the metal spacer 34 is Has a slit 35 cut. As the desiccant 36, molecular sieves or the like is suitable.
As shown in FIG. 4, four metal spacers 34 each having both ends cut at 45 degrees are prepared vertically and horizontally, and these are formed in a frame shape having a size that can be disposed at a position slightly inside the periphery of the glass plate 31. And a desiccant-containing spacer 33 is formed, and two of them are provided.
[0012]
Further, in addition to the desiccant-containing spacer 33, an intervening body 40 is provided. This interposed body 40 is formed of a synthetic resin having low thermal conductivity (for example, polyethylene or the like) as a raw material. Like the spacer 33, four bar-shaped objects 41 whose both ends are cut at 45 degrees are prepared. These are assembled into a frame having the same size as the spacer 33 to form the interposed body 40. Similarly, two intervening bodies 40 are provided.
[0013]
Assembling of the door 15 is performed as follows. First, the double glazing 30 is assembled. For that purpose, two glass plates 31 are prepared. Among them, a transparent resin coating containing a metal material is applied to the back surface of the glass plate 31 disposed outside. As shown in FIG. 6, the metal material in this coating can be energized through the terminals 43 and the electrodes 44, and functions as a heater that heats the back surface of the glass plate 31 by heat generation. I have.
On the other hand, the two desiccant-containing spacers 33 formed in a frame shape are overlapped and bonded. At this time, a heat ray reflective film 45 (for example, made of a polyester film) is sandwiched and stretched between the spacers 33. Next, the frame-shaped intervening bodies 40 are superimposed on the front and back sides of each spacer 33 and fixed by bonding.
[0014]
Then, the inner and outer two glass plates 31 sandwich the integrally joined spacer 33 and the interposed body 40 at the peripheral edge, are bonded, and are joined to each other. Finally, a sealing material 47 (for example, a sealant such as thiocol) is applied to the outer peripheral surface side of the spacer 33 and the interposed body 40 between the two glass plates 31 and solidified, so that the multilayer glass 30 is formed. Is completed.
The periphery of the double-glazed glass 30 is fitted into the fitting groove 22 of the corresponding vertical frame 21A or horizontal frame 21B, and the ends of the vertical frame 21A and the horizontal frame 21B are abutted and fixed. Thus, the frame 20 is formed. Since the frame 20 is assembled in a state where the hollows of the frames 21A and 21B communicate with each other without leakage, a heat insulating material 26 made of urethane foam resin or the like is foam-filled in the hollow of the frame 20. Note that the frame body 20 may be left hollow without filling with a heat insulating material.
Thereby, the door 15 in which the double-glazed glass 30 is fitted into the heat insulating frame 20 is completed. A magnet packing 23 is mounted on the back surface of the frame 20, and a handle 17 is mounted at a predetermined position on the front surface.
[0015]
When the door 15 as described above is attached to the opening 13 and closed as shown in FIG. 5, the double glazing 30 provided with the heat insulating air layer 49 is stretched over the door 15. Good heat insulation inside and outside of the refrigerator is achieved. In addition, the heat ray reflective film 45 is stretched in the heat insulating air layer 49 to restrict the intrusion of heat rays outside the refrigerator, thereby further improving heat insulation. In addition, the rear surface of the outer door 15 is heated to prevent dew condensation on the front surface. Furthermore, since the two glass plates 31 are assembled with the desiccant-containing spacer 33 interposed therebetween, the moisture of the heat insulating air layer 49 is removed, and particularly the surface of the inner glass plate 31 (the surface facing the heat insulating air layer 49) is removed. Fogging is prevented.
[0016]
On the other hand, in the peripheral portion of the door 15, the cold inside the refrigerator is transmitted to the surface 20 </ b> A of the frame 20 (the wall surface on the front side of the fitting groove 22) via the frame 20, the glass plate 31, and the metal spacer 34. May be done. However, in this embodiment, since the intermediate body 40 having low thermal conductivity is mounted between the glass plate 31 and the spacer 33 at two places, the conduction of cold heat is suppressed and the surface portion of the frame body 20 is reduced. The cooling of 20A is also suppressed. Therefore, the occurrence of dew condensation on the surface portion 20A of the frame 20 is prevented. Accordingly, it is not necessary to equip the frame 20 with a dew condensation prevention heater, so that the structure is simplified and power can be saved.
[0017]
<Second embodiment>
FIG. 7 shows a second embodiment of the present invention. In the double-glazed glass 30A of the second embodiment, one thick interposed body 40A made of a synthetic resin having low thermal conductivity is sandwiched between two desiccant-containing spacers 33. I have. The heat ray reflection film 45 is stretched between the intervening body 40A and the inner spacer 33.
The same operation and effect as the first embodiment can be obtained. Only one intervening body 40A is required, and the number of components can be reduced.
<Third embodiment>
In the double glazing 30B of the third embodiment shown in FIG. 8, between the inner desiccant-containing spacer 33 and the inner glass plate 31, it is thick and also covers the outer peripheral surface side of the desiccant-containing spacer 33. An intermediate body 40B made of a synthetic resin having a low thermal conductivity and having an L-shaped cross section is sandwiched.
The same operation and effect as in the first embodiment can be obtained.
[0018]
<Fourth embodiment>
FIG. 9 shows a fourth embodiment of the present invention. In the double glazing 30C of the fourth embodiment, the heat ray reflective film 45 is provided in two layers as compared with the second embodiment. As the heat ray reflection film 45, a film having a width approximately twice as large as the width of the multilayer glass 30C is prepared at first.
After the left end of the heat ray reflective film 45 is applied to the surface of the left edge of the interposition body 40A, the heat ray reflective film 45 is extended toward the right edge, wound around the rear surface, and returned to the rear surface of the left edge. Then, from this state, the front and back of the interposition body 40A are sandwiched and bonded by the desiccant-containing spacer 33.
[0019]
In the heat insulating air layer 49, the heat ray reflection film 45 is stretched in two layers, so that the intrusion of the heat ray outside the refrigerator is more reliably restricted, and the heat insulating effect is exhibited. Since the outer glass plate 31 is heated from the back side by the heat rays reflected by the heat ray reflection film 45, it is possible to eliminate the need to apply a coating including a metal material serving as a heater to prevent defrosting.
Since the heat ray reflective film 45 is stretched in two layers by winding the middle in the width direction around one side edge of the interposition body 40A, the work of stretching the two layers, which has been considered difficult, is relatively easily performed. be able to.
[0020]
<Fifth embodiment>
FIG. 10 shows a fifth embodiment of the present invention. In the double glass 30D of the fifth embodiment, contrary to the fourth embodiment, on both sides of one desiccant-containing spacer 33, two interposed bodies made of synthetic resin having low thermal conductivity are used. 40D is sandwiched. The heat ray reflective film 45 similar to that of the fourth embodiment is stretched in two layers by winding a part of the widthwise direction around one side edge of the spacer 33.
In addition, a biting piece 52 in an oblique posture protrudes from an end of the outer peripheral surface of both interposed bodies 40D on the side in contact with the glass plate 31.
Therefore, when the sealing material 47 is filled on the outer peripheral surface side of the spacer 33 and the interposed body 40D, the biting piece 52 of the interposed body 40D is fixed so as to bite into the sealing material 47 and is fixed. Is more firmly attached to the regular position.
[0021]
<Sixth embodiment>
In addition, as means for making the interposition body bite into the sealing material, as in the case of the double-glazed glass 30E of the sixth embodiment shown in FIG. 11, a bite with a head 54A from the outer peripheral surface of the interposition body 40E. The piece 54 may be set up.
<Seventh embodiment>
Further, like the double-glazed glass 30F of the seventh embodiment shown in FIG. 12, a groove 55 having a narrow entrance is cut on the outer peripheral surface of the interposition body 40F, and the sealing material 47 is inserted into the groove 55 and solidified. You may make it do.
