Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an exterior material structure for preventing dew condensation applied to window frames and the like.

[Background technology]

Generally, residential windows are made of aluminum or plastic sash with a single pane of glass.

However, in winter or at night, there is a large temperature difference between indoors and outdoors, so condensation tends to form on the glass plate or sash surface. This is mainly due to the lack of heat insulation properties of the glass plates and sash. For this reason, it is preferable to use members with excellent heat insulation properties, such as double-glazed glass and plastic sashes.

Figure 2 shows a sash structure with ordinary double-glazed glass installed, in which two glass plates 3 and 3' are fitted into the inner groove 2 of the aluminum sash 1, and two glass plates 3 and 3' are fitted into the sash 1. A spacer 5 is interposed between the glass plates 3 and 3',
A heat insulating air layer 6 is formed between both glass plates 3 and 3'. The spacer 5 is formed of a rectangular cylinder made of aluminum, and a desiccant 7 is filled inside. Then, the lower surface of the spacer 5 is filled with a sealant 8.

However, during the winter and at night when the outside temperature drops, the second
As shown by arrow A in the figure, the cold air is drawn through the spacer 5 from the glass plate.
It is transmitted to the indoor side through the air, and condensation forms on the indoor glass panel surface9.
Otherwise, as shown by arrow B in the figure, cold air is transmitted to the indoor side through the connecting plate 10 that connects the front plate and the rear plate of the sash, and condensation 9 forms on the rear plate of the sash. Ta.

That is, the spacer 5 and the connecting plate 10 each serve as a heat bridge that transfers heat from inside and outside the room.

[Purpose of the invention]

An object of the present invention is to provide an exterior material structure for preventing dew condensation.

[Disclosure of the invention]

In the exterior material structure for preventing dew condensation of the present invention, a heat storage material is brought into contact with a heat conductive connecting part provided in an exterior frame and serving as a heat bridge between indoors and outdoors, and the heat stored in this heat storage material is transferred through the connecting part. It is characterized by absorbing heat transfer from cold air.

An embodiment of the present invention will be described based on FIG. Note that the same constituent members as shown in FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted. That is, this exterior material structure for preventing condensation is, as shown in FIG.
The first heat storage materials 11 are housed in the upper and lower spaces of the connecting plate 10 that connects the rear plate 1b and the rear plate 1b.
1 is brought into contact with both sides of the connecting plate 10, and the glass plate 3.
The second heat storage material 12 is brought into contact with the lower surface of the aluminum spacer 5 interposed between the spacers 3' and 3'.

As the heat storage material 11.12, for example, CaCl2.6+1
20°Naz11P04, 121 (20, etc.) can be used.These heat storage materials 11.12 absorb heat and liquefy when the temperature is high during the day, and generate heat and solidify at night when the temperature drops. For this reason, as shown by arrows C and D in Fig. 1, the heat transferred from the outdoor cold air at night or in the winter is absorbed by the heat stored in the heat storage material 11 and 12 during the day, and the heat is absorbed by the glass plate on the indoor side. This can prevent dew condensation from adhering to the surfaces of the sash 3' and the sash rear plate 1b.

In this embodiment, the first heat storage material 11 and the second heat storage material 12 are provided in the sash depending on the location where dew condensation occurs, but they may be provided in only one of them if necessary. Further, the present invention is not limited to sashes, but can be suitably used for exterior materials having heat conductive joints that can become heat bridges, such as metal frames of panels, for example.

〔Effect of the invention〕

According to this invention, it is possible to prevent the occurrence of dew condensation due to the heat storage material housed inside.
