As shown in FIGS. 1 and 2, the inner window 8 is pulled between the upper frame 27 and the lower frame 28, the left and right vertical frames 29 and 29, and the upper and lower frames 27 and 28 attached to the inner peripheral side surfaces of the four-circle frame 26. It is equipped with an external sash 30a and an internal sash 30b that can be opened and closed in a different manner. The frames 27, 28, 29 and the stiles of the shoji 30a, 30b are made of resin. The shoji screens 30a and 30b have a stile around four circumferences and an inner glass 2 held by the stiles around the four circumferences, and the inner glass 2 is a double glazing. Since there is a wooden frame 26 between the frame 9 of the outer window 7 and the frames 27, 28, 29 of the inner window 8, the outer window 7 and the inner window 8 are thermally separated from each other.

A ventilation breath 31 is provided on the outer peripheral side of the upper frame 27. As shown in FIG. 1, the ventilation breath 31 is formed of a hollow aluminum profile having a rectangular cross section, and vertically long slit-shaped ventilation holes 32a and 32b are spaced apart in the left-right direction on the finding surfaces on the outdoor side and the indoor side. A large number of ventilation portions 5 are provided, whereby the indoor ventilation portion 5 communicating from the intermediate layer 6 to the indoor space is provided. A filter 33 is provided on the indoor side of the indoor ventilation portion 5 to prevent the intrusion of dust, pollen, and the like.

As shown in FIGS. 2 and 3, the rectifying body 3 is divided into two in the left-right direction, and the divided left and right rectifying bodies 3a and 3b are placed on the lower surface of the upper frame 26 as shown in FIG. It is detachably attached to the attached attachment 34 with bolts and nuts 35.
As shown in FIG. 1, the rectifying body 3b located on the indoor side of the inner sash 10b of the outer window 7 has a plate-shaped hanging portion 36 facing the indoor side of the outdoor ventilation portion 4 and an outdoor surface of the hanging portion 36. It has fins 37 that protrude outward to the outside and are provided along the left-right direction. The fins 37 are formed of parts separate from the hanging portion 36, and a plurality of fins 37 are provided at intervals in the vertical direction. In this way, by providing the fins 37 in the left-right direction on the hanging portion 36 of the rectifying body 3b, the air flowing in from the outdoor ventilation portion 4 formed in the ventilation small window 18 of the internal sash 10b is shunted in the left-right direction (external sash). It can be guided to the 10a side). As shown in FIGS. 2 and 3, the rectifying body 3a located on the indoor side of the outer sash 10a of the outer window 7 has only the hanging portion 36 and does not have the fins 37.

This fitting is provided with resin frames 27, 28, 29 and an inner window 8 using a stile and double glazing, and as shown in FIG. 1, is intermediate with the outdoor ventilation portion 4 of the outer window 7. Air flows indoors and outdoors through the indoor ventilation portion 5 of the layer 6 and the inner window 8 (the arrow in FIG. 1 indicates the air flow), and at that time, the air flows through the intermediate layer 6 of the outer glass 1 of the outer window 7. By detouring along the inner surface and the outer surface of the inner glass 2 of the inner window 8, the heat that escapes from the room to the outside is recovered, or the heat that enters the room from the outside is discarded to the outside, thereby. Heat transfer in the direction opposite to the inflow direction of air is hindered, and a very excellent heat insulating effect is exhibited.

Explaining the case of winter, the indoor pressure is adjusted to a negative pressure by a ventilation fan or the like, and as shown in FIG. 1, the air flows from the outdoor to the indoor of the fitting. The cold air (outside air) flowing in from the outdoor ventilation portion 4 formed on the door end side of the ventilation small window 18 of the inner sash 10b of the outer window 7 hits the hanging portion 36 of the rectifying body 3 and is guided by the fins 37. It flows in the left-right direction (on the side of the external shoji 10a) (see FIG. 2). After that, as shown in FIG. 1, the sash 10a of the outer window 7 and the sash 10b, which have a low temperature and a strong downward flow, descend while being attracted to the flow along the inner surface of the outer glass 1. After that, the cold air flows to the bottom of the intermediate layer 6 and then turns back, is warmed by transferring the heat in the room from the inner glass 2 of the inner window 8, rises along the outdoor surface of the inner glass 2, and during this time, the inner glass. The heat that escapes from 2 to the outside is recovered by the flow of air. Further, when the window receives sunlight, the heat of sunlight flows through the intermediate layer 6 along the inner side surface of the outer glass 1 of the outer window 7 and the outer surface of the inner glass 2 of the inner window 8 in this way. Can be obtained. After that, the warmed air flows into the room through the indoor ventilation portion 5 above the inner window 8. Even when the air passes through the indoor ventilation portion 5, the heat of the ventilation breath 31 and the upper frame 27 heated by the heat in the room is recovered by the air flow. By taking the warmed air into the room, the recovered heat can be returned to the room.

In this way, by bypassing the inside of the intermediate layer 6 along the outer window 7 and the inner window 8, the solar heat can be acquired, and the heat transferred from the room to the outside can be recovered by the air flow. By returning it to the room, there is almost no heat loss from the room to the outside, which hinders the heat transfer from the indoor side to the outdoor side, which is the direction opposite to the direction in which the air flows, and provides extremely high heat insulation. At the same time, the outside air can be warmed and taken into the room, so that the heating load can be suppressed.

In the summer, the pressure inside the room is adjusted to positive by using a ventilation fan, etc., so that the air flows from the room to the outside, contrary to the winter. The air (inside air) that has flowed out from the indoor ventilation portion 5 of the inner window 8 to the intermediate layer 6 hits the rectifying body 3 and changes its flow downward, and the temperature of the indoor air is lower than that of the outdoor air. It flows downward along the outdoor surface of 2. After that, the air is folded back at the lower part of the intermediate layer 6, and the heat of the outer glass 1 of the outer window 7 is transferred to rise along the indoor side surface of the outer glass 1, and during this time, the air enters the room from the outside through the outer glass 1. The incoming heat and solar heat are recovered by the flow of air. After that, air is discharged to the outside through the outdoor ventilation portion 4 of the outer window 7. Then, when the air is released to the outside, the heat recovered from the outer glass 1 and the like and the solar heat are discarded to the outside. By recovering the solar heat and the heat transmitted from the outside to the room by the air flow and discarding it outside the room, the acquisition of the solar heat can be suppressed, and the direction from the outside to the inside of the room is opposite to the direction in which the air flows out. Since heat transfer to is hindered, an excellent heat insulating effect can be exhibited, the room can be kept cool, and the cooling load can be suppressed.

As described above, this fitting includes an outer glass 1, an inner glass 2, and a rectifying body 3, and has an outdoor ventilation portion 4 that leads from an outdoor space to an intermediate layer 6 between the outer glass 1 and the inner glass 2. The rectifying body 3 is provided in the intermediate layer 6 and guides the air from the outdoor ventilation portion 4 downward and in the left-right direction. Air flows in one direction along the inner surface of the outer glass 1 in communication with the outside, folded back at the end of the intermediate layer 6, and flows in the other direction along the outer surface of the inner glass 2 in communication with the room. As a result, by recovering the heat that escapes from the room to the outside or by discarding the heat that enters the room from the outside to the outside, it is possible to reduce the inflow and outflow of heat from the window and suppress the heating / cooling load. The rectifying body 3 guides the air from the outdoor ventilation portion 4 downward and in the left-right direction, so that the air can be directed in the left-right direction even when the outdoor ventilation portion 4 is provided only in a part of the fitting in the left-right direction. It is distributed in a well-balanced manner throughout the building, reducing the inflow and outflow of heat from the windows mentioned above, and efficiently exerting the effect of suppressing the heating and cooling load.
