Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a double-glazed glass door used to enhance the heat insulation effect of glass windows and the like.

[Background technology]

As shown in Figure 1, double glazing is generally
A hollow layer 11 formed by interposing a hollow spacer 1 between glass plates 10, 10 is filled with dry air or gas to provide heat insulation performance, and is inserted into a sliding frame (sash frame) 3. It is something. that time,
In order to dry the air sealed inside, a desiccant 2 is generally filled inside the spacer 1, as shown in the figure. However, this desiccant 2
Because it cannot be replaced without destroying the main unit, the lifespan of the desiccant also extends to the lifespan of the double-glazed glass. In the figure, 6 is a setting block, 12 and 13 are sealants, and 17 is a bead.

[Purpose of invention]

The purpose of this invention is to solve the above-mentioned problems of the conventional door and to provide a double-glazed glass door in which only the desiccant can be replaced without destroying the main body.

[Disclosure of invention]

In order to achieve the above object, this invention is a glass door equipped with double-glazed glass and a frame fitted around the double-glazed glass. The gist of the glass door is that the hollow container is removably fitted, the inside is filled with a desiccant, and the inside of the hollow container is open to a hollow layer of double-glazed glass. This will be explained in detail below along with drawings showing examples thereof.

FIG. 2 shows an exploded explanation of the main parts of the glass door according to this invention. Figure 3 shows the whole thing. An elongated hollow container 5 is removably fitted into the groove 4 of the frame 3, and its position is fixed by setting blocks 6, 6. The interior of the hollow container 5 is filled with a desiccant 7 and communicates with the inside of the hollow spacer 9 through a vent pipe 8.

Also in this invention, the double-glazed glass has a hollow layer 11 formed between the glass plates 10 and 10 by interposing a spacer 9, and a primary sealing material 12.
The periphery is sealed by a secondary sealing material 13. A hole 15 is provided on the bottom surface of the spacer 9 so that the ventilation tube 8 of the hollow container 5 penetrates the secondary sealant 13 and communicates with the inside of the spacer, and at the same time, so that the inside of the spacer 9 communicates with the hollow layer 11. Holes 16 are provided on the top surface.

As in the prior art, this double-glazed glass is inserted into the frame 3 in which the hollow container 5 is installed in the groove 4. The inside of the hollow container 5 communicates with the inside of the spacer 9 through the vent pipe 8, and the spacer 9 communicates with the hollow layer 11 through the hole 16, so the desiccant 7 absorbs the air in the hollow layer 11. Can prevent moisture.

The desiccant 7 is replaced by removing the double-glazed glass from the frame and replacing the old hollow container containing the desiccant with a similar hollow container filled with a new desiccant. In other words, the hollow container is of a cartridge type.

In the above embodiment, also inside the spacer 9,
If it is filled with a desiccant, a higher drying effect can be obtained. The hollow container 5 is desirably made of a high-strength material such as steel so that it can withstand the weight of the double-glazed glass. Furthermore, if the hollow container has sufficient strength, there is no need to use a setting block.

Above, we have explained the case where the desiccant filled in a removable hollow container communicates with the hollow layer via a spacer, but if the desiccant communicates with the hollow layer, However, the present invention is not limited to this manner.

The hollow container can also be attached to the edge of double glazing.

Note that although the glass is shown to be thick in the drawing, it is actually quite thin.

[Effect of idea]

Since this invention is constructed as described above, only the desiccant can be replaced without destroying the double-glazed glass body.
