The inner window 14 is, as shown in FIGS. It is equipped with an outer shoji 39a and an inner shoji 39b that are openable and closable in a different manner. Frames 36, 37, 38 and frames of shoji 39a, 39b are made of resin. Glass 40 of shoji 39a, 39b is double glazing. Since a wooden frame 24 is provided between the window frame 1 of the outer window 13 and the frames 36, 37, 38 of the inner window 14, the outer window 13 and the inner window 14 are thermally separated.
A ventilation brace 41 is provided on the upper part of the upper frame 36 . The ventilation brace 41 is provided with a large number of ventilation holes 42 on the facing surfaces of the outdoor side and the indoor side, and is provided with a ventilation part 43 communicating from the intermediate layer 17 to the indoor space.

In addition to providing an inner window 14 using resin frames 36, 37, 38 and stiles and multi-layered glass 40, this double window has a ventilation path 9 provided in the ventilation frame 2 of the outer window 13 and an intermediate window. Air flows inside and outside the room through the layer 17 and the ventilation part 43 of the inner window 14, and at that time, the air flows around the intermediate layer 17 along the inner surface of the outer window 13 and the outer surface of the inner window 14. , the heat transfer in the direction opposite to the direction of air inflow is prevented, exhibiting excellent heat insulation performance, and contributing to further reduction of the electricity cost of air conditioning equipment.

In the winter, the inside of the room is adjusted to a negative pressure by using a ventilation fan or the like, and as shown in FIG. The cold air (outside air) flowing in from the ventilation frame 2 of the outside window 13 flows out downward along the indoor side surface of the glass 8 of the outside window 13 because the indoor side ventilation port 7 is opened downward. After that, the cold air flows to the bottom of the intermediate layer 17 by the cold draft, turns back, is warmed by the heat of the room transmitted from the glass 40 of the inner window 14, and rises along the outdoor side of the glass 40, The heat escaping from 40 to the outside is recovered by the air flow. After that, the warmed air flows into the room through the ventilation part 43 above the inner window 14. - 特許庁Even when the air passes through the ventilation part 43, the heat of the ventilation brace 41 and the upper frame 36 warmed by the heat in the room is recovered by the flow of air. By introducing the warmed air into the room, the recovered heat can be returned to the room.
In this way, by detouring the inside of the intermediate layer 17 along the outer window 13 and the inner window 14, the heat transmitted from the room to the outside is recovered by the air flow and returned to the room, thereby Very high thermal insulation is obtained since there is almost no heat loss from the to the outside. In addition, since the outside air can be warmed and taken into the room, the people in the room do not feel the cold wind, and the heating efficiency is good.

In the summer, the room is adjusted to a positive pressure by using a ventilation fan or the like so that the air flows from the room to the outside, contrary to the winter. The air (inside air) coming out of the ventilation part 43 of the inner window 14 hits the rectifying plate 45 and changes its flow downward, and since the temperature of the indoor air is lower than that of the outdoor, the air flows along the outdoor side of the glass 40 of the inner window 14. After that, it turns back at the lower part of the intermediate layer 17, and the heat is transferred to the glass 8 of the outside window 13, so that it rises along the indoor side surface of the glass 8 of the outside window 13. The heat entering the room is recovered by the air flow. After that, the air is discharged outside through the ventilation frame 2 of the outer window 13. - 特許庁When the air passes through the ventilation frame 2, the heat entering the room along the ventilation frame 2 is recovered by the flow of air. Then, the heat recovered from the glass 8 and the ventilation frame 2 is released to the outdoors by releasing the air to the outdoors. In this way, the heat transferred from the outside to the inside of the room is collected by the flow of air and discharged to the outside of the room. It works well and keeps the room cool.

In this double-glazed window, since the ventilation frame 2 provided on the outer peripheral side of the window frame 1 of the outer window 13 is provided with the ventilation path 9 communicating with the outside of the room, the window frame 1 of the outer window 13 and the shoji 15, 16 are ventilated. There is no need to set up a department. The ventilation frame 2 communicates with the inside and outside of the room through the ventilation port 6 of the vertical ventilation frame 3, the hollow portions 18a and 18b of the vertical ventilation frame 3, the hollow portion 29b of the upper ventilation frame 4, and the ventilation port 7 of the upper ventilation frame 4. Since the path 9 is formed, it is possible to prevent the infiltration of rainwater while having the ventilation path 9 in the outer window 13, and to ensure the watertight performance. In addition, since the ventilation path 9 is configured with the vertical ventilation frame 3 and the upper ventilation frame 4 as described above, the length of the ventilation path 9 is increased, so that the air flows through the ventilation path 9, and the air is released. The heat insulation effect is improved by preventing heat transport in the direction opposite to the flow direction.
