Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an airflow window, and more specifically, in a sash with a double-glazed window structure that is fixedly attached to a building frame, indoor air flows inside the double-glazed window. This invention relates to a heat recovery sash provided with a passage.

<Prior Art> It has been a common construction method in the past to attach a window frame sash of a double-glazed window structure with an outdoor shoji and an inner window to a building frame by fixing it in advance.

<Problems to be Solved by the Invention> However, in such a double-glazed window structure, the atmosphere of various outside air conditions in summer and winter is conducted to the indoor shoji through the outdoor shoji, and the indoor atmosphere near the indoor shoji is as described above. A problem has arisen in that indoor environmental conditions are deteriorated due to the large influence of various outside air conditions.

<Means for Solving the Problems> The present invention has been researched and developed in view of the above circumstances, and its purpose is to provide an indoor air passage ( In order to avoid the possibility that various outside air conditions may have a negative effect on the indoor environment, by forming a circulation duct, the indoor surface of the outdoor shoji is It is an object of the present invention to provide a heat recovery sash in which a thin plate such as a film that reflects light is attached to the side, and the air in the passage is exhausted or supplied to a heat exchange device such as an air conditioner.

<Example> Hereinafter, a preferred embodiment of the present invention shown in the drawings will be described in detail. In FIG. 1, reference numeral 1 denotes a heat recovery sash of the present invention, which is formed into a substantially rectangular shape.

The heat recovery sash 1 is rotatably equipped with a sash stile 2 of an indoor shoji on the indoor side of an opening frame 9 fixedly supported on a building frame 8, and a sash frame 2 of an indoor shoji is provided on the inner edge of the sash sill 2. A glass shoji 4 is attached via a shoji (see FIG. 2).

That is, the sash stile 2 consists of an upper upper stile 5, a lower lower stile 6, and left and right frames 21, 22, into which the glass shoji 4 is fitted. Further, a rotary piece 7 is formed projecting from the upper stile 5, and this rotary piece 7 is rotatably supported on a support piece 10 provided on the opening frame 9. As a result, the indoor shoji can be moved to the above-mentioned rotating piece 7.
and the support piece 10 to rotate toward the indoor A side.

A sash stile 11 of an outdoor shoji is fixed to the outdoor side (left side in FIG. 2) of the opening frame 9 described above. A glass shoji 13 is also fitted inside this sash frame 11 via a grating tile 12 as described above.

A blind box 14 is attached to the upper stile 5, and the blind box 14 includes the following:
A blind 15 is housed so that it can be taken in and out from the room A side by appropriate means.

In FIG. 2, a ventilation hole 16 is formed between the lower stile 6 of the sash stile 2 of the indoor shoji screen and the lower frame 91 of the opening frame body 9. This vent hole 16 plays the role of a handle when rotating the indoor shoji screen, and since it is formed along the lower frame 91, it has a favorable appearance.
Further, this vent 16 is formed so as to communicate with the indoor side A and a passage 17 between the indoor glass shoji 4 and the outdoor glass shoji 12.

The passage 17 is connected to an exhaust duct 18 attached to the upper part of the upper frame 92 of the opening frame body 9, and is configured to exhaust indoor air from the exhaust duct 18 to the outdoor side B via an exhaust pipe inside the ceiling. There is.

If necessary, a reverse-angled blinding plate 19 is integrally attached to the lower end of the inner surface of the sash frame 11 so as to be located on an extension of the above-mentioned ventilation hole 16. The blind plate 19 extends in the direction of the vent 16, and therefore, the indoor side is shielded from the indoor side A and the outdoor side B through the vent 16.

In addition, in the figure, the reference numeral 20 is a ceiling installed inside the building.

Since the present invention has the configuration as described above,
The air on the indoor side A is sucked in from the vent 16 as shown by the solid arrow in FIG. It is sucked in and exhausted to the outdoor side B through an exhaust pipe in the ceiling or the like, or supplied to a heat exchanger (not shown).

Therefore, the indoor air filling the passage 17 is
It becomes an air curtain layer, and the environmental conditions on the indoor side A do not change due to factors from outside.

As described above, according to the present invention, if the heat recovery sash of the present invention is attached to the building frame in advance, indoor air can be circulated between the glass shoji on the indoor side and the glass shoji on the outdoor side. A curtain layer is created, and this curtain layer effectively blocks the interior and exterior.

<Effects of the Invention> Therefore, there is no possibility that various outside air conditions will affect the indoor environment through the indoor shoji screen, and indoor circulation can always be maintained in a good condition. In addition, a thin plate such as a film such as a half mirror is attached to the glass shoji on the outdoor side to reflect light from the indoor side, so in the summer, the incident light is reflected by the thin reflective plate and is reflected from the glass shoji on the outdoor side. Although the effect of radiant heat is small, it is sufficient to exhaust the air in the passage outside to the outside.On the other hand, in winter, this thin reflective plate does not reflect all the incident light, but allows some of the light to pass through. The air in the passage is warmed by the transmitted light, and by supplying this air to a heat exchange device of an air conditioner or heater, it becomes a heat recovery sash if it is energy efficient.
