Embodiments of the present invention will be described below based on the drawings. 1 to 3 show a first embodiment of the fitting of the present invention. This fitting is a double-glazed window comprising an exterior window (outside partition) 1 installed on the outdoor side of the window opening of a building, and an interior window (inner partition) 2 installed on the indoor side of the window opening. ing.

As shown in FIGS. 1 and 2, the exterior window 1 includes a frame 6 fixed to a window opening of a building, and an exterior shoji 7a and an interior shoji 7b housed in the frame 6 in a sliding manner so as to be openable and closable. In the closed state, the outer shoji 7a is located on the left side when viewed from the indoor side, and the inner shoji 7b is located on the right side.
The frame 6 is composed of an upper frame 8, a lower frame 9, and left and right vertical frames 10, 10 made of aluminum sections. The outer shoji 7a and the inner shoji 7b are constructed by assembling an upper stile 11, a lower stile 12, a door sill 13, and a matching stile 14 made of aluminum shapes, and fitting a glass 15 inside the stile. .
As shown in FIG. 1, a ventilation stile 16 is provided on the inner circumferential side of the lower stile 12 of the outer shoji 7a and the inner shoji 7b. The ventilation frame 16 is provided with ventilation holes 17 and 18 on the outdoor side wall and the indoor side wall, and forms a ventilation section 4 that communicates from the outside to the intermediate layer 19 between the outside window and the inside window. As shown in FIG. 3(a), the ventilation holes 17 and 18 are in the form of vertically long slits, and are provided in large numbers over the entire length of the stile at intervals in the left-right direction. As shown in FIG. 1, the vent hole 17 in the outdoor wall is formed on an inclined surface facing diagonally downward, and is provided at a lower position than the vent hole 18 in the indoor wall. This makes it difficult for rainwater to enter from the ventilation section 4. A shutter plate 20 for opening and closing the ventilation section 4 is provided inside the ventilation section 4.

As shown in FIGS. 1 and 2, the inner window 2 has an upper frame 22 and a lower frame 23 attached to the inner circumferential side of the picture frame 21 with four circumferences, and vertical frames 24, 24 on the left and right sides, and a sliding structure between the upper and lower frames. It is equipped with an outer shoji 25a and an inner shoji 25b that can be opened and closed, and in the closed state, the outer shoji 25a is located on the left side and the inner shoji 25b is located on the right side when viewed from the indoor side. The frames 22, 23, and 24 are made of resin. The outer shoji 25a and the inner shoji 25b include glass (double-glazed glass) 26 and a resin frame surrounding the glass. Since there is a wooden frame 21 between the frame 6 of the outer window 1 and the frames 22, 23, and 24 of the inner window 2, the outer window 1 and the inner window 2 are thermally separated.
A ventilation breather 27 is provided at the top of the upper frame 22. The ventilation breather 27 is provided with a large number of ventilation holes 28 on the outside and inside facing surfaces, and is provided with a ventilation section 5 that communicates from the intermediate layer 19 to the interior of the room. As shown in FIG. 3(b), the ventilation holes 28 are in the form of vertically long slits, and are provided in large numbers over the entire longitudinal length of the upper frame 22 at intervals in the left-right direction. A filter 29 is provided on the indoor side of the ventilation section 5 to prevent dust, pollen, etc. from entering.

As shown in FIG. 1, the intermediate layer 19 is provided with a fluid regulator 3 hanging down from the upper frame 21. The flow regulator 3 is formed of a transparent resin plate, and is detachably attached to the outdoor side of the ventilation brace 27 with a knob bolt 31 via a spacer 30, and faces the outdoor side of the ventilation section 5 with a gap. ing.

This fitting has a ventilation part 4 provided in the lower part of the outer window 1 to communicate with the outdoors, and a ventilation part 5 provided in the upper part of the inner window 2 to communicate with the indoor space, and the shoji 7a of the outer window 1 and the inner window 2. , 7b, 25a, 25b can be kept closed for ventilation. This fitting has good sound insulation performance because the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2 are vertically separated from each other.

The sound insulation performance of the fittings of the first embodiment was measured. For comparison, the sound insulation performance was also measured for a comparative example in which the ventilation section 4 of the outer window 1 was provided above the inner and outer shoji 7a, 7b (the ventilation stile 16 was placed on the inner circumferential side of the upper stile 11). The sound insulation performance was measured in accordance with JIS A1416 "Method for measuring the air sound insulation performance of building materials in a laboratory". FIG. 5 shows the results of the sound insulation performance test.
As is clear from the figure, in the comparative example, there is a drop in the vicinity of 400 to 1000 Hz, but in the first embodiment, such a drop disappears, and it can be seen that the sound insulation performance is improved.

In addition, the fittings of the first embodiment have the effect of improving heat insulation performance by allowing air to flow through the intermediate layer 19.
In the winter, the indoor pressure is adjusted to negative using a ventilation fan or the like installed in the room, so that air flows through the fittings from outside into the room, as shown in FIG. 4(a). The cold outside air flowing in through the ventilation part 4 of the outside window 1 is warmed by the indoor heat being transmitted from the glass 26 of the inside window 2, and rises along the outdoor side of the glass 26 of the inside window 2. The heat that escapes from the room to the outside is recovered by air flow. In addition, when solar radiation is received through a window, solar heat can be acquired while flowing through the intermediate layer 19 along the outer surface of the glass 26 in this manner. Thereafter, most of the warmed outside air flows into the room through the vent 5 provided above the inner window 2, allowing the recovered heat to be returned to the room. A part of the outside air rising along the outer surface of the inner window 2 flows back to the outdoor side and loses a part of the recovered heat. This reduces the amount of air flowing back to the outside of the room.

In this way, by flowing the outside air from bottom to top in the middle layer 19 along the outer surface of the glass 26 of the inner window 2, solar heat can be obtained, and the heat escaping from the glass 26 of the inner window 2 can be transferred to the air. By collecting the air and returning it indoors, the loss of heat from indoors to outdoors is reduced, and this prevents heat transport from the indoor side to the outdoor side, which is the opposite direction to the direction of air inflow. In addition to providing insulation, the heating load can be reduced because outside air is warmed and introduced indoors. In addition, since the outside air is warmed and brought into the room, people staying indoors do not feel cold air.

In the summer, the pressure inside the room is adjusted to positive using a ventilation fan, etc., so that air flows from the room to the outside, as shown in FIG. 4(b). The inside air flowing out from the ventilation part 5 of the inner window 2 to the intermediate layer 19 descends along the outdoor side of the glass 26 of the inner window 2 because the temperature is lower than that of the outside, and during this time, it flows from the outside through the glass 15 of the outside window 1. Heat entering the room is recovered by air flow. Thereafter, the heat flows out of the room through the ventilation section 4 provided at the lower part of the outside window 1, and the recovered heat is disposed of outside.
In this way, the heat transferred from the outdoors to the indoors is recovered by the air flow and discarded outdoors, which prevents heat transport from the outdoor side to the indoor side, which is the opposite direction to the direction in which the air flows out, resulting in excellent insulation. It works effectively and keeps the room cool.

6 and 7 show a second embodiment of the fitting of the present invention (an embodiment of the invention according to claim 1). The fittings of this embodiment are also double-glazed windows comprising an outer window 1 and an inner window 2, and the frame 6 of the outer window 1 and the frame of the inner window 2 are integrally formed.
As shown in FIG. 6, the outer window 1 has an outer shoji 7a and an inner shoji 7b that open and close in a sliding manner within a frame 6, and a ventilation frame 16 is provided only on the inner circumferential side of the lower stile 12 of the outer shoji 7a. A ventilation section 4 communicating with the outside is provided only at the lower part of the outer shoji 7a.
As shown in FIG. 6, the inner window 2 has an outer shoji 25a and an inner shoji 25b that open and close in a sliding manner within a frame 6, and a ventilation stile 16 is provided only on the inner circumferential side of the upper stile 32 of the inner shoji 25b. A ventilation section 5 communicating with the interior of the room is provided only at the upper part of the inner shoji 25b. Therefore, in the fittings of the second embodiment, as shown in FIG. It's in a different position.

Similar to the first embodiment, the fittings of the second embodiment allow ventilation through the ventilation section 4 of the outer window 1 and the ventilation section 5 of the inner window 2, and the ventilation section 4 of the outer window 1 and the ventilation section of the inner window 2. 5 are spaced apart vertically and at positions shifted from side to side, making it even more difficult for sound to propagate, further improving sound insulation performance.

FIG. 8 shows an example in which a flow regulator 3 is attached to the fittings of the second embodiment. The flow regulator 3 is detachably attached to an angle 35 attached to the lower surface of the upper frame 8 with a knob bolt 31, and faces the outdoor side of the ventilation section 5 of the inner window 2.
By installing the flow regulator 3 in this way, in the same way as in the first embodiment described above, the heat that escapes from indoors to outdoors is recovered by the air flow and returned indoors in winter, and the heat that escapes from outdoors to indoors is returned to indoors in summer. By recovering the incoming heat through airflow and discharging it outside, insulation performance is improved and heating and cooling loads can be reduced.

FIG. 9 shows a third embodiment of the fitting of the present invention (an embodiment of the invention according to claim 2). The fittings of this embodiment are also double-glazed windows comprising an outer window 1 and an inner window 2, and the frame 6 of the outer window 1 and the frame of the inner window 2 are integrally formed.
As shown in FIG. 9, the outer window 1 has an outer shoji 7a and an inner shoji 7b that open and close in a sliding manner within a frame 6, and a ventilation frame 16 is provided only on the inner circumferential side of the upper stile 11 of the outer shoji 7a. A ventilation section 4 communicating with the outside is provided only at the upper part of the outer shoji 7a.
As shown in FIG. 9, the inner window 2 has an outer shoji 25a and an inner shoji 25b that open and close in a sliding manner within a frame 6, and a ventilation stile 16 is provided only on the inner circumferential side of the upper stile 32 of the inner shoji 25b. A ventilation section 5 communicating with the interior of the room is provided only at the upper part of the inner shoji 25b. Therefore, in the fittings of the third embodiment, similarly to the second embodiment, the range 33 where the ventilation part 4 of the outer window 1 is provided and the range 34 where the ventilation part 5 of the inner window 2 is provided are (See Figure 7).

Similar to the first and second embodiments, the fittings of the third embodiment can perform ventilation through the ventilation section 4 of the outer window 1 and the ventilation section 5 of the inner window 2, and the ventilation section 4 of the outer window 1 and the ventilation section 5 of the inner window 2 Since the ventilation portions 5 are provided in a range shifted to the left and right, the sound insulation performance is good.

FIG. 10 shows an example in which a flow regulator 3 is attached to the fittings of the third embodiment. The flow regulator 3 is detachably attached to an angle 35 attached to the lower surface of the upper frame 8 with a knob bolt 31, and faces the indoor side of the ventilation section 4 of the outer window 1 and the outdoor side of the ventilation section 5 of the inner window 2. ing.
In the fittings of this embodiment, the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2 are provided in a range shifted from left to right, and the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2 are provided in a range shifted from left to right. Since the fluid regulating fluid 3 is provided opposite to the fluid regulating fluid 3, the passage of sound is prevented by the fluid regulating fluid 3, so that the sound insulation performance is improved.

Furthermore, in the fittings of this embodiment, the air flows around the intermediate layer 19 along the inner surface of the glass 15 of the outer window 1 and the outer surface of the glass 26 of the inner window 2, so that heat is removed while providing ventilation. It works to improve insulation performance by reducing entry and exit.
In the winter, the pressure inside the room is adjusted to negative using a ventilation fan, etc., so that air flows through the fittings from outside into the room, as shown in Figure 11(a). The cold outside air flowing in from the vent 4 of the outer window 1 changes its flow direction downward by hitting the regulating fluid 3, and then flows along the inner surface of the glass 15 of the outer window 1, where the temperature is low and the force of the downward flow is strong. It descends while being pulled by the current. After that, the cold outside air flows to the bottom of the intermediate layer 19, turns around, is warmed by the indoor heat being transmitted from the glass 26 of the inner window 2, and rises along the outdoor side of the glass 26, and during this time, the cold outside air flows from the glass 26 to the outside. The heat that escapes is recovered by air flow. Furthermore, when the window receives solar radiation, solar heat can be acquired while the air flows through the intermediate layer 19 along the inner surface of the outer window 1 and the outer surface of the inner window 2 in this manner. Thereafter, the warmed outside air flows into the room through the ventilation section 5 above the inner window 2. By bringing the warmed outside air into the room, the recovered heat can be returned to the room.

In this way, the air flows around the intermediate layer 19 along the outer window 1 and the inner window 2, making it possible to obtain solar heat and collect the heat transmitted from indoors to outdoors through the air flow, thereby increasing the indoor By returning the heat to the outside, there is almost no loss of heat from indoors to outdoors, and this prevents heat transport from the indoor side to the outdoor side, which is the opposite direction to the direction of air inflow, resulting in extremely high insulation properties. At the same time, the outside air can be warmed and brought indoors, reducing the heating load. The flow of air in the intermediate layer 19 matches the flow direction of natural convection caused by the temperature difference between the inside and outside, and the air does not flow backwards to the outdoor side as in the case of Fig. 4(a), so the insulation performance is improved. It can be further improved.

In the summer, the pressure inside the room is adjusted to positive using a ventilation fan, etc., so that air flows from the room to the outside, contrary to the case in the winter, as shown in FIG. 11(b). The inside air flowing out from the ventilation part 5 of the inner window 2 to the intermediate layer 19 hits the regulating fluid 3 and changes its flow downward, and since the temperature of the inside air is lower than the outside, it flows downward along the outdoor side of the glass 26 of the inside window 2. flows to After that, the inside air turns around at the bottom of the intermediate layer 19, and as the heat from the glass 15 of the outside window 1 is transferred, it rises along the indoor side of the glass 15 of the outside window 1, and during this time, it enters the room from outside through the glass 15. The heat from the sun and the heat from the sun are collected by air flow. Thereafter, air is discharged to the outside through the ventilation portion 4 of the exterior window 1. Then, by releasing the air to the outside, the heat and solar radiation collected from the glass 15 and the like are disposed of outside.

In this way, by collecting solar heat and heat transmitted indoors from the outdoors through air flow and discarding it outdoors, the acquisition of solar heat can be suppressed. Since heat transport to the interior of the room is obstructed, it exhibits an excellent insulation effect, keeping the room cool and reducing the cooling load. The flow of air in the intermediate layer 19 matches the flow direction of natural convection caused by the temperature difference between the inside and outside, and the air does not flow back into the room as in the case of FIG. 4(b), so the insulation performance is improved. It can be further improved.

Another example of arranging the range 33 of the outer window 1 in which the ventilation part 4 is provided and the range in which the ventilation part 5 of the inner window 2 is provided is shifted left and right is as shown in FIG. 12(a). The range 33 in which the ventilation portion 4 of the inner window 2 is provided may be arranged in the middle part (center) in the left-right direction, and the range 34 in which the ventilation part 5 of the inner window 2 is provided may be arranged in both left and right ends. In addition, as shown in FIG. 12(b), the range 33 where the ventilation part 4 of the outer window 1 is provided is placed at both left and right ends, and the range 34 where the ventilation part 5 of the inner window 2 is provided is placed in the middle in the left and right direction. (center).

FIG. 13 shows a fourth embodiment of the fitting of the present invention. The outer window 1 has an outer shoji 7a and an inner shoji 7b that can be opened and closed in a sliding manner in a frame 6. A ventilation stile 16 is arranged only on the inner circumferential side of the upper stile 11 of the outer shoji 7a, A ventilation section 4 that communicates with the outside is provided only at the upper part of 7a.
In the inner window 2, a ventilation brace 27 is provided on the upper frame 22 as in the first embodiment, and the ventilation portion 5 communicating with the room is provided in the ventilation brace 27.
The ventilation portion 4 of the outer window 1 is provided only on the outer shoji 7a, and the ventilation portion 5 of the inner window 2 is provided over the entire length of the upper frame 22, so the area of the ventilation portion 4 of the outer window 1 (the area of the ventilation hole 18) The total area) is approximately half the area of the ventilation portion 5 of the inner window 2 (the total area of the ventilation holes 28).
A fluid regulator 3 is provided in the intermediate layer 19 so as to hang down from the upper frame 21, and the fluid regulator 3 faces the ventilation portion 4 of the outer window 1 and the ventilation portion 5 of the inner window 2.

The fittings of the fourth embodiment can perform ventilation through the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2, and the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2 are opposite to each other. 3 provides good sound insulation performance. Furthermore, by making the area of the ventilation part 4 of the outer window 1 smaller than the area of the ventilation part 5 of the inner window 2, it becomes difficult for outdoor sounds to be transmitted to the intermediate layer 19, so that sound insulation performance is improved.
In addition, air flows through the intermediate layer 19 in a detour along the inner surface of the outer window 1 and the outer surface of the inner window 2, thereby recovering heat escaping from the indoors to the outdoors in the winter and from the outdoors in the summer. By collecting the heat that enters the room and discarding it outside, it is possible to reduce the amount of heat that enters and exits while providing ventilation, thereby reducing the heating and cooling load.

An indoor space 42 is formed. The ventilation frame main body 37, the outdoor side cover material 38, and the indoor side cover material 39 are each elongated members made of aluminum shapes.

As shown in FIG. 15, the outdoor cover material 38 has a facing wall 43, an upper wall 44, and a lower wall 45, and has a hook-shaped locking portion 46 provided at the tip of the upper wall 44. The lower wall 45 is secured to the groove provided on the upper part of the outdoor side of the ventilation frame body 37, and the lower wall 45 is overlapped with the outdoor end of the side wall of the auxiliary member 47 with an L-shaped cross section attached to the indoor side of the upper frame 8, and screwed from below. (not shown) is fixed and attached. A side wall of the auxiliary member 47 is provided with an outdoor ventilation hole 49 that opens downward and faces the outdoors. A hanging piece 50 is provided on the outdoor side of the outdoor side ventilation hole 49 so as to hang down from the outdoor side ventilation hole 49 . An insect screen 51 is attached to the outdoor ventilation hole 49 to prevent insects from entering. In this way, by providing the outdoor vent hole 49 with a downward opening and by providing the hanging piece 50 on the outdoor side thereof, rainwater is prevented from entering through the outdoor vent hole 49.

As shown in FIG. 15, in the ventilation frame main body 37, an intermediate space 41 is formed by an upper wall 52, a lower wall 53, an outdoor wall 54, and an indoor wall 55. A large ventilation hole 56 is formed in the outdoor side wall 54, and an insect screen 51 is attached to the outdoor side of the ventilation hole 56. A water return piece 57 protruding toward the outdoor side is provided below and adjacent to the ventilation hole 56, and the water return piece 57 prevents rainwater from entering the ventilation hole 56. A vent hole 58 is formed in the indoor side wall 55 to be smaller than a vent hole 56 on the outdoor side.
The ventilation frame 36 has a large ventilation hole 56 formed in the outdoor side wall 54 of the ventilation frame main body 37 and a small ventilation hole 58 formed in the indoor side wall 55 as described above, so that the outdoor side space 40 and the intermediate space 41 can be separated. The pressure is equal to the outside air. This prevents rainwater from being sucked into the ventilation section 4. The indoor space 42 has an atmospheric pressure close to that of the room.

As shown in FIG. 15, the indoor cover material 39 is formed into a hollow shape with a rectangular cross section by combining two members with a substantially L-shaped cross section, and a vent hole 59 in the outdoor wall communicates with a vent hole 58 in the vent frame body 37. It is formed by A vent hole 60 facing the interior (middle layer) is provided in the bottom wall of the indoor cover material 39 and opens downward. A filter 61 is attached to the ventilation hole 60 to prevent dust, pollen, etc. from entering.

FIG. 16 shows an example of the arrangement of the ventilation holes 60. In the example shown in FIG. 16(a), a large number of ventilation holes 60 are provided over the entire length of the ventilation frame 36. The area of the ventilation portion 4 of the outer window 1 (the total area of the ventilation holes 60) is approximately the same as the area of the ventilation portion 5 of the inner window 2 (the total area of the ventilation holes 28).
In the example shown in FIG. 16(b), the number of ventilation holes 60 is reduced and they are arranged at equal intervals over the entire length of the ventilation frame 36. The area of the ventilation portion 4 of the outer window 1 (the total area of the ventilation holes 60) is approximately 1/10 of the area of the ventilation portion 5 of the inner window 2 (the total area of the ventilation holes 28).
In the example shown in FIG. 16(c), the ventilation holes 60 are arranged close to both left and right ends of the ventilation frame 36. The area of the ventilation portion 4 of the outer window 1 (the total area of the ventilation holes 60) is approximately 1/10 of the area of the ventilation portion 5 of the inner window 2 (the total area of the ventilation holes 28).
In the example shown in FIG. 16(d), the ventilation holes 60 are arranged closer to the middle part (center part) of the ventilation frame 36 in the left-right direction. The area of the ventilation portion 4 of the outer window 1 (the total area of the ventilation holes 60) is approximately 1/10 of the area of the ventilation portion 5 of the inner window 2 (the total area of the ventilation holes 28).

As shown in FIG. 15, the fluid regulator 3 is removably attached to the indoor side surface of the ventilation frame 36 with a knob bolt 31 from the indoor side.

As shown in the same figure, in the case of FIG. 16(a) in which many ventilation holes 60 are provided along the entire length, a drop is seen around 400 to 1000 Hz, but in FIG. 16(b), in which the number of ventilation holes 60 is reduced, In c) and (d), such depression is eliminated and the sound insulation performance is improved. Among those with a reduced number of ventilation holes 60, the ones shown in FIGS. 16(c) and 16(d) are arranged closer to the ends or the center than the ones shown in FIG. 16(b), which are distributed over the entire length. The sound insulation performance was better.

The fittings of the fifth embodiment can perform ventilation through the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2, and the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2 are opposite to each other. 3 provides good sound insulation performance. Furthermore, by making the area of the ventilation part 4 of the outer window 1 smaller than the area of the ventilation part 5 of the inner window 2, it becomes difficult for outdoor sounds to be transmitted to the intermediate layer 19, so that sound insulation performance is improved. In particular, the sound insulation performance is further improved by arranging the ventilation holes 60 in a concentrated manner in the middle portion or the end portion in the left-right direction.
In addition, air flows through the intermediate layer 19 in a detour along the inner surface of the outer window 1 and the outer surface of the inner window 2, thereby recovering heat escaping from the indoors to the outdoors in the winter and from the outdoors in the summer. By collecting the heat that enters the room and discarding it outside, it is possible to reduce the amount of heat that enters and exits while providing ventilation, thereby reducing the heating and cooling load.

In the fittings of the fifth embodiment, even when the area of the ventilation section 5 of the inner window 2 is made smaller than the area of the ventilation section 4 of the outer window 1, the area of the ventilation section 4 of the outer window 1 is smaller than the area of the ventilation section 4 of the inner window 2. Similar to the case where the area of the portion 5 is made smaller, there is an effect of improving the sound insulation performance. In short, the area of the ventilation section 4 of the outer window 1 and the area of the ventilation section 5 of the inner window 2 may be made different. This point also applies to embodiments other than the fifth embodiment (first to fourth and sixth embodiments). In addition, it is more preferable to make the area of the ventilation part 4 of the outer window 1 smaller than the area of the ventilation part 5 of the inner window 2 in order to prevent rainwater from entering.

FIG. 18 shows a sixth embodiment of the fitting of the present invention (an embodiment of the invention according to claim 2). The structure of the fittings of the sixth embodiment is the same as that of the fifth embodiment shown in FIG. The arrangement of 28 is different. The ventilation hole 60 of the ventilation part 4 of the outer window 1 is provided in the left half region, as shown in FIG. 18(a). The ventilation hole 28 of the ventilation part 5 of the inner window 2 is provided in the right half region, as shown in FIG. 18(b). That is, the ventilation portion 4 of the outer window 1 and the ventilation portion 5 of the inner window 2 are provided in ranges shifted from each other to the left and right.

In the fittings of the sixth embodiment, ventilation can be performed through the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2, and the ventilation part 4 of the outer window 1 and the ventilation part 5 of the inner window 2 are located in a range shifted from left to right. Because of this, the sound insulation performance is good.

As described above, the fittings of the first embodiment include an outer partition (outer window) 1 and an inner partition (inner window) 2, and a ventilation section 4 communicating with the outdoors at the bottom of the outer partition 1. Since the upper part of the inner partition 2 has a ventilation part 5 communicating with the room, ventilation can be performed through the ventilation part 4 of the outer partition 1 and the ventilation part 5 of the inner partition 2. Since the ventilation portions 4 of 1 and the ventilation portions 5 of the inner partition 2 are vertically separated from each other, the sound insulation performance is good.
In addition, during ventilation, the outside air enters from the ventilation part 4 of the outer partition 1 and rises along the outer surface of the inner partition 2 and then flows into the room from the ventilation part 5 of the inner partition 2. Inside air coming out of the ventilation part 5 of the partition body 2 descends along the outer surface of the inner partition body 2 and then flows out from the ventilation part 4 of the outer partition body 1 to the outside, thereby escaping from the room to the outdoors in winter. Heat is recovered by air flow and returned indoors, and in the summer, heat that enters the room from outside is recovered by air flow and disposed of outside, reducing the amount of heat entering and exiting while providing ventilation. Load can be reduced.
By providing the flow regulator 3 in the intermediate layer 19, backflow of air can be suppressed, and the above-mentioned effect can be exerted more efficiently.

The fitting of the second embodiment (an embodiment of the invention according to claim 1) includes an outer partition (outer window) 1 and an inner partition (inner window) 2, and the outer partition 1 communicates with the outdoors at the bottom. Since the inner partition 2 has a ventilation part 5 in the upper part that communicates with the room, ventilation can be performed through the ventilation part 4 of the outer partition 1 and the ventilation part 5 of the inner partition 2. Moreover, the ventilation portions 4 of the outer partition 1 and the ventilation portions 5 of the inner partition 2 are vertically separated from each other and are provided in a horizontally shifted range, so that the sound insulation performance is good.
In addition, during ventilation, the outside air enters from the ventilation part 4 of the outer partition 1 and rises along the outer surface of the inner partition 2 and then flows into the room from the ventilation part 5 of the inner partition 2. Inside air coming out of the ventilation part 5 of the partition body 2 descends along the outer surface of the inner partition body 2 and then flows out from the ventilation part 4 of the outer partition body 1 to the outside, thereby escaping from the room to the outdoors in winter. Heat is recovered by air flow and returned indoors, and in the summer, heat that enters the room from outside is recovered by air flow and disposed of outside, reducing the amount of heat entering and exiting while providing ventilation. Load can be reduced.
When the flow regulator 3 is provided in the intermediate layer 19, backflow of air can be suppressed, and the above-mentioned effect can be exerted more efficiently.
Sound insulation performance is improved by providing the ventilation portion 4 of the outer partition 1 or the ventilation portion 5 of the inner partition 2 closer to the middle in the left-right direction, or closer to one or both ends in the left-right direction. .
By making the areas of the ventilation portions 4 of the outer partition 1 and the ventilation portions 5 of the inner partition 2 different, sound insulation performance is improved.

The fittings of the third and sixth embodiments (embodiments of the invention according to claim 2) include an outer partition body (outer window) 1 and an inner partition body (inner window) 2, and the outer partition body 1 has Since the inner partition 2 has a ventilation part 5 in the upper part that communicates with the room, ventilation can be performed through the ventilation part 4 of the outer partition 1 and the ventilation part 5 of the inner partition 2. Moreover, since the ventilation portions 4 of the outer partition 1 and the ventilation portions 5 of the inner partition 2 are provided in a range shifted from left to right, the sound insulation performance is good.
When the flow regulator 3 is provided in the intermediate layer 19, the outside air entering from the ventilation portion 4 of the outer partition 1 flows in one direction along the inner surface of the outer partition 1, and the air flows in one direction near the end of the intermediate layer 19. The air turns back and flows in the other direction along the outer surface of the inner partition 2, and either flows into the room through the ventilation section 5 of the inner partition 2, or the inside air exiting from the ventilation section 5 of the inner partition 2 flows into the room through the ventilation section 5 of the inner partition 2. It flows in one direction along the outer surface, turns around near the end of the intermediate layer 19, flows in the other direction along the inner surface of the outer partition 1, and flows out to the outdoors through the ventilation section 4 of the outer partition 1. In the winter, the heat that escapes from inside the room to the outside is collected by the airflow and returned to the room, and in the summer, the heat that enters the room from outside is collected by the airflow and discarded to the outside, thereby providing ventilation. At the same time, the amount of heat entering and exiting can be reduced, and the heating and cooling load can be reduced. Furthermore, the provision of the flow regulator 3 has the effect of improving sound insulation performance.
Sound insulation performance is improved by providing the ventilation portion 4 of the outer partition 1 or the ventilation portion 5 of the inner partition 2 closer to the middle in the left-right direction, or closer to one or both ends in the left-right direction. .

The fittings of the fourth, fifth, and sixth embodiments include an outer partition (outer window) 1, an inner partition (inner window) 2, and a flow regulator 3. Since the inner partition 2 has a ventilation part 5 in the upper part that communicates with the room, ventilation can be performed through the ventilation part 4 of the outer partition 1 and the ventilation part 5 of the inner partition 2. Since the fluid regulator 3 is provided opposite the ventilation section 4 of the body 1 and the ventilation section 5 of the inner partition 2, the passage of sound is obstructed by the fluid regulation 3, so that sound insulation performance is good.
Since the flow regulator 3 is provided facing the ventilation part 4 of the outer partition 1 and the ventilation part 5 of the inner partition 2, the outside air entering from the ventilation part 4 of the outer partition 1 is prevented from entering the outer partition 1. It flows in one direction along the side surface, turns around near the end of the intermediate layer 19, flows in the other direction along the outer surface of the inner partition body 2, and flows into the room through the ventilation portion 5 of the inner partition body 2, or flows inside the room. Internal air coming out of the ventilation section 5 of the partition 2 flows in one direction along the outer surface of the inner partition 2, turns around near the end of the intermediate layer 19, and flows in the other direction along the inner surface of the outer partition 1. During the winter, the heat that escapes from inside the room to the outside is collected by the air flow and returned to the inside of the room, and during the summer, the heat that enters the room from outside is By collecting the waste through air flow and disposing of it outdoors, it is possible to reduce the amount of heat entering and exiting the room while providing ventilation, thereby reducing the heating and cooling load.
Sound insulation performance is improved by providing the ventilation portion 4 of the outer partition 1 or the ventilation portion 5 of the inner partition 2 closer to the middle in the left-right direction, or closer to one or both ends in the left-right direction. .

The outer partition may be anything that partitions the outdoor space and the intermediate layer, and may be a shutter, a shutter, a roll screen, etc. in addition to a glass-filled outer window. The inner partition may be anything that partitions the middle layer and the indoor space, and may be a curtain, a roll screen, a shoji, etc. in addition to a glass-filled inner window.
The flow regulator prevents the air flow from being obstructed by the collision between the descending air and the rising air between the outer partition and the inner partition, and prevents the air flow from being obstructed by the inner surface of the outer partition and the outer surface of the inner partition. Any material can be used as long as it can form a detouring air flow along the path, and in addition to plate-shaped materials, blinds, roll screens, honeycomb screens, etc. may be used.
