The ventilation small window 18 has an outer glass door 21 located on the door trailing side (meeting frame side) and an inner glass door 22 positioned on the door trailing side. By sliding it open, an outdoor ventilation part 4 communicating from the outdoor space to the intermediate layer 6 is formed on the door tip side.
The ventilation small window 18 may be incorporated into the inner shoji 10b from the beginning, or may be incorporated into the existing inner shoji 10b of the window later.

The inner window 8 is, as shown in FIGS. It is equipped with an outer shoji 30a and an inner shoji 30b that are openable and closable in different ways. Frames 27, 28, 29 and frames of shoji 30a, 30b are made of resin. The shoji 30a, 30b has a four-circumference frame and an inner glass 2 held by the four-circumference frame, and the inner glass 2 is double-glazed glass.

It has fins 37 protruding to the outside of the vehicle and provided along the left-right direction. The fins 37 are formed as separate parts from the drooping portion 36, and are provided in plurality at intervals in the vertical direction. In this way, by providing the fins 37 in the left-right direction on the hanging part 36 of the rectifier 3b, the air flowing in from the outdoor ventilation part 4 formed in the small ventilation window 18 of the inner shoji 10b flows in the left-right direction (outside shoji). 10a side). The rectifying body 3a located on the indoor side of the outer shoji 10a of the outer window 7 has only the drooping portion 36 and does not have the fins 37, as shown in FIGS.

In addition to providing resin frames 27, 28, 29 and an inner window 8 using a stile and double-glazed glass, this fitting has an outdoor ventilation part 4 of the outer window 7 and an intermediate window 8 as shown in FIG. Air flows inside and outside the room through the layer 6 and the indoor ventilation part 5 of the inner window 8 (the arrows in FIG. 1 indicate the air flow). 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 discharged to the outside. Heat transfer in the direction opposite to the direction of air flow is prevented, providing excellent heat insulation.

To explain the case of winter, the room is adjusted to a negative pressure by a ventilation fan or the like, and as shown in FIG. Cold air (outside air) flowing in from the outdoor ventilation part 4 formed on the door tip side of the ventilation small window 18 of the inner shoji 10b of the outer window 7 hits the hanging part 36 of the rectifier 3 and is guided by the fins 37. It flows in the left-right direction (toward the outside shoji 10a) (see FIG. 2). After that, as shown in FIG. 1, it descends while being attracted by the flow along the inner surface of the outer glass 1 of the outer window 7 of the outer window 7, which has a low temperature and a strong downward flow. After that, the cold air flows under the intermediate layer 6 and then folds back, is warmed by heat transfer from the inner glass 2 of the inner window 8, rises along the outdoor side of the inner glass 2, and is between the inner glass. The heat escaping from 2 to the outside is recovered by the air flow. In addition, when the window receives solar radiation, while the air flows through the intermediate layer 6 along the inner 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, the solar radiation heat can be obtained. After that, the warmed air flows into the room through the indoor ventilation part 5 above the inner window 8. - 特許庁Even when the air passes through the indoor ventilation part 5, the heat of the ventilation brace 31 and the upper frame 27 warmed by the indoor heat is recovered by the air flow. 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 6 along the outer window 7 and the inner window 8, the air can obtain solar heat, and the heat transmitted from the indoor to the outdoor can be recovered by the air flow, By returning it indoors, there is almost no heat loss from the indoors to the outdoors, and this prevents the heat transfer from the indoors to the outdoors, which is the opposite direction of the air flow, resulting in extremely high thermal insulation. In addition, since outside air can be warmed and taken into the room, the heating load can be suppressed.

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 (internal air) flowing out from the indoor ventilation part 5 of the internal window 8 to the intermediate layer 6 hits the rectifying body 3 and changes its flow downward, and since the temperature of the indoor air is lower than that of the outdoor, the inner glass of the internal window 8 It flows downward along the outdoor side of 2. After that, the air is folded back at the lower part of the intermediate layer 6, heat is transferred to the outside glass 1 of the outside window 7, etc., and rises along the indoor side surface of the outside glass 1. During this time, the air enters the room from the outside through the outside glass 1. Recover heat and solar heat by air flow. After that, the air is discharged to the outside through the outdoor ventilation part 4 of the outer window 7. - 特許庁Then, the heat collected from the outside glass 1 and the like and the heat from the sun are released to the outdoors by releasing the air to the outdoors. In this way, the heat from the sun and the heat transmitted from the outside to the inside of the room are collected by the flow of air and discharged to the outside. Since heat transfer to the air conditioner is impeded, an excellent heat insulation effect is exhibited, the room is kept cool, and the cooling load can be suppressed.
