Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-flow window, and more specifically, to a sash having a double-window structure fixedly attached to a building frame, in which a room air passage is provided inside the double-window. About the heat recovery sash.

[0002]

2. Description of the Related Art A window frame sash having a double window structure provided with an outdoor shoji and an inner window is fixed and attached to a building frame in advance, which is a construction method which has been conventionally well constructed.

[0003]

However, in such a double glazing structure, the atmosphere of various outdoor air conditions such as summer or winter is conducted to the indoor shoji through the outdoor shoji, and the indoor atmosphere near the indoor shoji is the above-mentioned. There has been a problem that the environmental conditions inside the room are deteriorated due to the large influence of the atmosphere under various outside air conditions.

[0004]

The present invention was researched and developed in view of the above circumstances, and an object of the present invention is to provide a passage for indoor air between an outdoor shoji and an indoor shoji. By forming a circulation duct), a sash having a double structure preliminarily attached to a building frame so as to avoid the possibility that the atmosphere of various outside air conditions may adversely affect the indoor environment. In the heat recovery sash that discharges air or supplies it to a heat exchange device such as an air conditioner, a blind is further installed in the passage, and the passage in the upper frame of the opening frame for fitting the indoor shoji and the outdoor shoji It is to provide a heat recovery sash in which a rising wall is provided on the side and the end of the exhaust duct is fixed to the rising wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention shown in the drawings will be described in detail below. In FIG. 1, reference numeral 1 is a heat recovery sash of the present invention, which is formed in a substantially rectangular shape.
The heat recovery sash 1 is rotatably provided with a sash frame 2 for indoor shoji on the indoor side of an opening frame 9 fixedly supported by a building frame 8, and a grechan 3 (Fig. Two
The glass shoji 4 is attached via the (refer to FIG. 3).

That is, the sash frame 2 comprises an upper frame 5 on the upper side, a lower frame 6 on the lower side, and left and right frames 21, 22. The glass screens 4 are fitted in the respective frames 5, 6, 21, 22. ing. A turning piece 7 is formed so as to project from the upper frame 5, and the turning piece 7 is rotatably supported by a supporting piece 10 provided on the opening frame 9. As a result, the indoor shoji turns to the room A side by the turning piece 7 and the support piece 10.

A sash frame 11 of an outdoor shoji is fixed to the outdoor side of the opening frame 9 (on the left side in FIG. 2). In this sash frame 11, the same as the above
A glass shoji 13 is fitted through 2 through.

A blind box 14 is provided on the upper frame 5.
The blind 15 is housed in the blind box 14 so that it can be taken in and out from the room A side by an appropriate means.

In FIG. 2, a vent 16 is formed between the lower frame 6 of the sash frame 2 of the indoor shoji and the lower frame 91 of the opening frame 9. The ventilation hole 16 plays a role of a handle when the indoor shoji is rotated and is formed along the lower frame 91, which is preferable in appearance. The vent 16 is formed so as to communicate with the passage A between the indoor side A, the indoor glass door 4 and the outdoor glass door 12. This passage 1
The blind 15 is installed in the window 7, and the incident light can be adjusted also by the blind.

The passage 17 is connected to an exhaust duct 18 attached to the upper portion of the upper frame 92 of the opening frame 9 so that room air is exhausted from the exhaust duct 18 to the outdoor side B through the exhaust pipe inside the ceiling. It is configured. This exhaust duct 18 is shown in FIG.
As shown in FIG. 7, the exhaust duct 18 is attached by fixing the ends of the exhaust duct to rising walls 92a and 92b provided on the opposite side of the passage 17 in the upper frame 92, thereby facilitating the installation of the exhaust duct 18. ing.

If necessary, a blind plate 19 in the shape of an inverted angle is integrally attached to the lower end of the inner side surface of the sash frame 11 positioned on the extension line of the vent hole 16. The blind plate 19 extends in the direction of the ventilation port 16 described above, so that the interior side is shielded from the interior side A and the exterior side B through the ventilation port 16. In the figure, reference numeral 20 is a ceiling installed inside the building.

Since the present invention is constructed as described above, the air on the indoor side A is sucked in through the vent 16 as shown by the solid arrow in FIG. The passage 17 between the shoji 13 and the shoji 13 is filled with the duct 17 and then sucked into the duct 18 to be exhausted to the outside B through an exhaust pipe such as in the ceiling or supplied to a heat exchange device (not shown). Then, the indoor air filled in the passage 17 becomes an air-caten layer, and the indoor side A is caused by a factor from the outside.
The environmental conditions of are unchanged.

As described above, according to the present invention, if the heat recovery sash of the present invention is attached to the building body in advance, the indoor air is circulated between the indoor and outdoor glass screens. An air-curten layer of air is created, which effectively shields the interior and exterior.

[0014]

Therefore, there is no possibility that the atmosphere under various outside air conditions may affect the indoor environment through the indoor shoji, and the indoor environment can be maintained in a good condition. Moreover, since a thin plate that reflects the light on the indoor surface side of the glass screen on the outdoor side, for example, a film such as Hafmirer, is attached and a blind is installed, the incident light is reflected by the reflective thin plate in summer. Although it is less affected by the radiant heat from the glass door outside the room, it is sufficient to exhaust the air inside the passage to the outside, while in the winter, this reflective thin plate does not reflect all the incident light rays, and some Since the light ray is also transmitted, the transmitted light ray warms the air in the passage, and supplies this air to the heat exchange device of the air conditioner or the like, thereby becoming an energy-efficient heat recovery sash. Furthermore, it facilitates the installation of an exhaust duct that guides the air in the passage to the outside or guides it to the heat exchange device, and facilitates effective use of this heat recovery sash.
