Hereinafter, embodiments of the present invention will be described based on the drawings. 1 to 5 show a first embodiment of the double window of the present invention. As shown in FIG. 1, the double window system is provided with an outer window 1 on the outdoor side of the window opening 10 of the building, and an inner window 2 on the indoor side of the window opening 10, and the outer window 1 and the inner window 2 are provided. The intermediate layer 3 is provided with a honeycomb-shaped louver 7 suspended downward from above.

The outer window 1 includes a frame 11 fixed to the window opening 10, a sliding window 12a and an inner sliding window 12b which are housed in the frame in a staggered manner. The frame 11 is configured by combining the upper frame 13, the lower frame 14, and the left and right vertical frames 15, 15 with a frame. The outer sliding window 12a and the inner sliding window 12b are formed by combining the upper frame 16, the lower frame 17, the door stop frame 18, and the meeting stile 19, and embedding the glass 20 inside. The frames 16, 17, 18, 19 of the frame 11 and the sliding windows 12a, 12b are made of aluminum. As shown in Figs. 2 and 4, the upper frame 16 is provided with a plurality of vent holes 21a and 21b on the outdoor side and the front side of the indoor side, and constitutes a ventilating portion 4 that communicates with the inside and outside. Inside the upper frame 16, there is a setting in the longitudinal direction of the upper frame 16 The lid body 22 is slidable and can be opened and closed to the vent hole 21a on the outdoor side. The filter 23 is detachably provided on the front side of the indoor side of the upper frame 16 so as to cover the vent hole 21b on the indoor side.

The inner window 2 is provided with a frame 24 fixed to the window opening 10, an outer sliding window 25a and an inner sliding window 25b which are housed in the frame 24 in a staggered manner. The frame 24 is constructed by combining the upper frame 26, the lower frame 27, and the left and right mullion frames 48, 48. The outer sliding window 25a and the inner sliding window 25b are formed by combining the upper frame 28, the lower frame 29, the door stop frame 30, and the overlapping frame 31, and embedding glass (plural glass) 45 inside. The frame 24 and the frames 28, 29, 30, and 31 of the sliding windows 25a and 25b are made of resin. As shown in FIGS. 2 and 5, the upper frame 26 is provided with a plurality of vent holes 32a and 32b on the outdoor side and the front side of the indoor side, and a ventilating portion 5 that communicates indoors and outdoors is formed. Inside the upper frame 26, a porous material 6 that imparts an impedance to the air flowing through the vent 5 is buried. As the porous material 6, glass wool or urethane foam or the like is used. The filters 33 and 33 are detachably provided on the outdoor side of the upper frame 26 and the front side of the indoor side so as to cover the vent holes 32a and 32b.

As shown in Fig. 1, the honeycomb blinds 7 are formed into a screen shape of a double honeycomb (bee nest) structure using a non-woven fabric of polyester, and the screen is used to produce a double air layer and exhibits a high heat insulating effect. Further, the side portions on both sides of the honeycomb-shaped louver 7 are guided to a resin-made rail 34 which is attached to the rim of the window as shown in Fig. 3 to improve airtightness. Therefore, the middle layer 3 is partitioned into the outdoor side and the indoor side by the honeycomb-shaped louver 7, and the air on the outdoor side of the honeycomb-shaped louver 7 approaches the outdoor temperature, and the air on the indoor side of the honeycomb-shaped louver 7 approaches the indoor side. The temperature creates a temperature difference between the outdoor side and the indoor side of the honeycomb blind 7 . As shown in FIG. 1, between the lower end of the honeycomb blind 7 and the lower surface of the window frame, there is a space of several centimeters. Gap 35. The honeycomb louver 7 is expandable and contractible up and down by operating the operation unit 36. The operation portion 36 is inserted into the insertion portion 49 provided to penetrate the end portion of the upper frame 2 of the inner window 2 in the indoor/outdoor direction, and extends out of the indoor side, even if the sliding windows 25a, 25b of the inner window 2 are not opened, The operation of the honeycomb-shaped louver 7 is performed on the indoor side.

Here, the construction sequence of the double window will be described. First, the outer window 1 is provided on the outdoor side of the window opening 10. Next, a honeycomb-shaped louver 7 is provided in the window opening portion 10 on the indoor side of the outer window 1. Thereafter, a certain interval is formed on the indoor side of the outer window 1, and the inner window 2 is provided on the indoor side of the window opening 10. Alternatively, the honeycomb blinds 7 may be provided after the inner window 2 is provided.

Figure 6 shows the structure that has been incorporated into the double window. The room is partitioned by the floor 38, the wall 39, and the ceiling 40, and the floor covering 38, the wall 39, and the ceiling 40 are embedded with heat insulating materials to improve heat insulation. Sex. A window opening 10 is provided in one of the walls 39, and a double window is attached. The other wall 39 is provided with an opening 41 for ventilation, and a blower 42 is attached. In the winter, by operating the blower 42 to discharge the indoor air to the outside, the indoors are adjusted to a negative pressure, and the outdoor air is passed through the vent 4, the intermediate layer 3, and the inner window of the outer window 1. The vent 5 of the 2 is sent to the room and ventilated for 24 hours. In addition, in the construction, there is a well-known air-conditioning system for air-conditioning, and the temperature in the room can be maintained at a comfortable temperature of around 20 °C by using air-conditioning equipment. Fig. 6 shows a case where the heat pump 43 is employed as the air conditioner of the air conditioner. The heat pump 43 includes an indoor unit 43a and an outdoor unit 43b, and exchanges heat between the indoor and outdoor air by the built-in heat exchanger and the refrigerant circuit, and the air supply port 43c of the indoor unit 43a is in winter. The warm air is sprayed out into the room, and the cold air is sprayed out into the room during the summer. Further, in the heat pump 43, the indoor air discharged from the blower 42 is sent to the outdoor unit 43b through the duct 44 in the winter, and heat is recovered from the air, thereby saving the heating cost.

The double window is provided by using the frame 24 and the frames 28, 29, 30, 31 and the inner window 2 of the plurality of layers of glass 45, and the intermediate layer 3 between the outer window 1 and the inner window 2 The honeycomb louver 7 is provided to achieve the heat insulating effect, and the air is also allowed to flow indoors and outdoors through the vent portion 4 of the outer window 1, the intermediate layer 3, and the vent portion 5 of the inner window 2, thereby hindering the air. The heat transfer in the opposite direction of the inflow direction exerts a better thermal insulation effect. Here, for the case of the winter season, as shown in FIG. 1, the cold outdoor air flowing in from the vent portion 4 of the upper frame 16 provided in the sliding windows 12a, 12b of the outer window 1 passes through the honeycomb louver 7 and the outer window. When the sliding windows 12a and 12b of the first window are lowered, they are raised by the honeycomb louver 7 and the sliding windows 25a and 25b of the inner window 2. Between the two, the heat in the room is transmitted by the sliding windows 25a and 25b of the inner window 2, and the air can be warmed. Thereafter, the air flows into the vent portion 5 of the upper frame 2 of the inner window 2, and the porous material 6 provided therein is weakened, and the porous material 6 which is warmed by the heat of the room or The heat of the upper frame 26 is transmitted to the air, and is warmed to a temperature substantially the same as the temperature in the room, and flows into the room from the vent hole 32b on the indoor side. In this way, by causing air to flow back and forth in the intermediate layer 3 along the outer window 1 and the inner window 2, and imparting an impedance to the flow of air in the vent portion 5 of the inner window 2, the air is transmitted from the inside to the outside. The heat is recovered by the flow of the air and returned to the room, whereby there is almost no heat loss from the inside to the outside, so that a relatively high heat insulating property can be obtained. In addition, because the outside air is warmed up and then placed indoors, people in the room do not feel the cold wind, and the efficiency of the greenhouse is also good. In addition, the arrow pattern in the figure indicates the flow of air.

Further, by providing the porous material 6 in the vent portion 5 of the inner window 2, it is possible to prevent the air from flowing from the indoor side to the outdoor side due to the temperature difference between the upper portion and the lower portion of the window or the influence of the outdoor wind. Case. By arranging the vent 5 of the inner window 2 at the upper portion of the inner window 2 (Upper frame 26), the air rising in the intermediate layer 3 along the inner window 2 can be more efficiently placed into the room, and the temperature of the air flowing into the room can be increased. The honeycomb-shaped louver 7 is in a state of being pulled up to the middle or pulled to the highest state, because the air flowing in from the vent portion 4 of the outer window 1 touches the honeycomb louver 7 and follows the outer window 1 The lower back, so it can effectively improve the thermal insulation performance.

The impedance portion of the porous material 6 or the like provided in the vent portion 5 of the inner window 2 can be selected and used by preparing various types of impedance strengths for imparting air flow, and the amount of ventilation can be performed. Adjustment. For example, in a building, there are a plurality of rooms provided with the double window of the present invention, and the ventilation of each room is performed by a ventilating fan provided in a toilet or the like, and the use of the impedance in a wide room is small. If you use a larger impedance in a small room, you can ensure the appropriate amount of ventilation in each room in response to the width of the room.

Fig. 7 shows a second embodiment of the double window of the present invention. In this embodiment, the intermediate layer 3 between the outer window 1 and the inner window 2 is provided with a general louver 8. The heat insulating or airtightness of the louver 8 itself is relatively inferior to that under the honeycomb louver 7, but the louver 8 has a function of allowing air to flow along the outer window 1 and the inner window 2 In the same manner as in the first embodiment, the heat transferred from the indoor to the outside is recovered by the air flow and returned to the room, so that the heat insulating performance can be improved. Further, the louver 8 improves the heat insulating effect when the louver 8 is erected and the louver 8 is closed. Similarly to the case of the honeycomb louver 7, even if the louver 8 is pulled up to the intermediate position or pulled up to the highest position, the air flowing in from the vent 4 of the outer window 1 touches the louver 8 along the side. The way of the outer window 1 is turned down, so that the heat insulation performance can be effectively improved.

Fig. 8 shows a third embodiment of the double window of the present invention. Implementing a shape here In the state, an upper portion of the intermediate layer 3 between the outer window 1 and the inner window 2 is provided with a rectifying guide 9. The rectifying guide 9 has an inlet-side guide piece 47a that is bent downward toward the outdoor side, a backflow prevention piece 47b that has a vertical portion that is continuous from the lower end of the inlet-side guide piece 47a, and a portion that is bent toward the inside of the room side, and a backflow prevention piece 47b. The outlet side guide piece 47c, which is inclined toward the indoor side, causes the air in the intermediate layer 3 to flow back along the outer window 1 and the inner window 2 by the sheets 47a, 47b, 47c. The inlet-side guide piece 47a has a function of causing air flowing in from the vent portion 4 of the outer window 1 to be slid back down along the outer window 1, and the backflow prevention piece 47b has air to prevent the air rising along the inner window 2 from going to the room. The outer side countercurrent acts, and the outlet side guide piece 47c has an effect of inducing the air rising along the inner window 2 toward the vent portion 5 of the inner window 2. According to the present embodiment, as in the first and second embodiments, the heat transferred from the indoor to the outside can be recovered by the flow of air and returned to the room, thereby improving the heat insulating performance. Further, in the double window of the present embodiment, since the rectifying guide 9 is mostly shielded by the upper frame 26 and the upper frame 28 of the inner window 2 when viewed from the indoor side, it is like setting the honeycomb louver 7 or the louver 8 In the case of the case, there is an advantage that the field of view is not blocked.

Fig. 9 shows a fourth embodiment of the double window of the present invention. In this embodiment, the intermediate layer 3 between the outer window 1 and the inner window 2 is not provided with any elements. Even in the case where the air layer is not obstructed in the intermediate layer 3, the air in the intermediate layer 3 is cooled by the outdoor air temperature near the outer window 1 side, and the indoor air is close to the inner window 2 side. Warming, in addition, due to the cooling air falling and the warm air rising, in the intermediate layer 3, natural air flow along the outer window 1 and the inner window 2 is generated, and the heat in the room flows into the intermediate layer 3. The air is transmitted, and by the action of the porous material 6 provided in the venting portion 5 of the frame 26 above the inner window 2, the air can be prevented from flowing back from the indoor side to the outdoor side, so that the air is recovered by the flow of air. The heat transferred from the inside to the outside and returned to the room improves the insulation performance.

In the double window of the first to fourth embodiments, the temperature at the outdoor side is 0° C., the temperature on the indoor side is 20° C., and the internal and external pressures when the air flow rate from the outdoor to the room changes is obtained. The difference, the heat to the outside of the house, the thermal cross flow rate Uf of the frame, the thermal cross flow rate Ug of the glass, and the thermal cross flow rate Uw of the entire window. In order to compare with each other, the thermal cross flow rate Uw of the double window without the venting portion was also obtained. The analysis results are disclosed in FIG. Further, the relationship between the ventilation flow rate and the thermal cross flow rate Uw of the entire window is disclosed in FIG. Further, in the second embodiment in which the louver 8 is provided, the blade 46 of the louver 8 is analyzed in a state of being erected.

As is apparent from Figs. 10 and 11, the thermal cross flow rate Uw of the double window of the first to fourth embodiments is greatly reduced to 0.24 as compared with the case where the thermal cross flow rate Uw of the double window which is not ventilated is 2.12. The value of 1.58. The heat cross flow rate Uw is smaller as the flow rate is larger. In particular, in the first embodiment in which the honeycomb-shaped louver 7 is provided, the thermal cross-flow rate Uw is a relatively small value of 0.24 to 0.73, and the second embodiment in which the louver 8 is provided and the rectifying guide 9 are provided. The third embodiment also has a relatively small value of about one. Further, even in the fourth embodiment in which nothing is provided in the intermediate layer 3, it has been confirmed that the effect of sufficiently improving the heat insulating performance is obtained.

Fig. 12 is a view showing a fifth embodiment of the double window of the present invention. In the embodiment, the intermediate layer 3 between the outer window 1 and the inner window 2 is provided with a honeycomb-shaped louver 7 in the same manner as in the first embodiment, and the honeycomb-shaped louver 7 is provided with the outer surface 7a in the color or Dark color such as brown. In order to set the surface 7a on the outdoor side of the honeycomb louver 7 to a dark color, for example, a dark material may be used, or a dark film or a dark color coating may be applied. In this way, by setting the surface 7a on the outdoor side of the honeycomb louver 7 to a dark color, there is an advantage that the solar radiation absorption rate can be improved, and air warmed by sunlight can be introduced into the room.

In this embodiment, a transparent roller blind 49 is provided in the intermediate layer 3 between the outer window 1 and the inner window 2. On the outdoor side of the take-up shaft 50 of the transparent roller blind 49, a plate-like airflow blocking portion 51 is attached, whereby the air flowing in from the vent portion 4 of the outer window 1 is directed downward along the transparent roller blind 49. flow. In the case where the transparent roller blind 49 is provided in the intermediate layer 3, the air curtain is kept in a state in which the transparent roller blind 49 is lowered, and the air flowing along the outer window 1 and the inner window 2 is ensured without obstructing the view from the window.

The door wheel 58 is supported and can be slid to the left and right and opened and closed. As described above, when the intermediate layer 3 is provided with the sliding windows 53a and 53b using the translucent panel 56, even if rainwater is immersed from the venting portion 4 of the outer window 1 during strong wind and rain, such as a typhoon, the sliding window 53a can be utilized. 53b blocks the rain. In addition, since the translucent panel 56 is used, it does not obstruct the window Lookout. Further, the sliding windows 53a and 53b may be simple structures in which only an aluminum frame is attached to the upper and lower portions of the translucent panel 56 or only the translucent panel 56 is provided.

So far, although the case has been described in the winter, the double window of the present invention exhibits excellent heat insulating performance even in the summer even in the summer. In the summer, the indoor air is adjusted to a positive pressure by the blower 42, and the air flows from the indoor side to the outdoor side through the vent portions 4, 5 and the intermediate layer 3. Since the air temperature in the room is lower than that in the outdoor, the heat is transmitted to the air between the outer window 1 or the honeycomb louver 7 between the air flowing from the indoor side to the outdoor side and between the venting portions 4 and 5 and the intermediate layer 3. Since the heat is discharged to the outside together with the air, the heat transfer from the outdoor side to the indoor side in the opposite direction to the air outflow direction is hindered, and the superior heat insulating effect is exerted, and the interior is kept cool. Further, in the third embodiment in which the rectifying guide 9 is provided, in the summer, the direction of the rectifying guide 9 is set to be opposite to the indoor and outdoor in winter.

As described above, the double window of the present invention is formed by causing the air in the intermediate layer 3 to flow back along the outer window 1 and the inner window 2 to impart an impedance to the air flowing in the vent 5, thereby hindering the air. The thermal movement in the opposite direction of the flow direction results in extremely high thermal insulation properties. Even if a honeycomb louver or the like is provided only in the intermediate layer 3, the air in the intermediate layer 3 flows back and the impedance of the air flowing in the vent portion 5 is imparted, and the heat insulating performance is improved. Further, since the double window system of the present invention improves heat insulation while ventilating, it is suitable for a building that is ventilated for 24 hours.

The glass 20 and 45 of the outer window 1 and the inner window 2 may be a single-plate glass or a plurality of layers of glass. However, as in the embodiment, once the glass 20 of the outer window 1 is set as a single-plate glass, the inner window 2 is The glass 45 is provided as a plurality of layers of glass, and it is difficult to transfer to the intermediate layer 3 due to heat in the room. Therefore, it can be used especially in winter. On the contrary, when the glass 20 of the outer window 1 is provided as a plurality of layers of glass and the glass 45 of the inner window 2 is made of a single-plate glass, since the heat of the outdoor is difficult to transfer to the intermediate layer 3, it is particularly useful in summer. Its effect. Once both sides are set to multiple layers of glass, they can be used in both winter and summer. Further, even in the case where both of the sheets are made of a single-plate glass, heat is recovered by the flow of air in the intermediate layer 3, thereby improving the heat insulating performance in both winter and summer.

In addition, once the outer window 1 and the glass 20, 45 of the inner window 2 are provided, either the low-emission surface treated glass (low-e glass) or the low-radioactive film is applied. (1ow-e film) is applied to either or both of the indoor side surface of the glass 20 of the outer window 1 and the outdoor side surface of the glass 45 of the inner window 2, since the heat transfer due to radiation from the glass surface is reduced, Improve heat insulation performance. In the case where nothing is provided in the intermediate layer 3 or in the case where the rectifying guide 9 is provided, when the honeycomb louver 7 or the louver 8 is raised, the influence of radiation becomes large, so such countermeasure It is effective. Further, the low-radioactive film may be applied to the honeycomb-shaped louver 7 or the louver 8, the roller blinds 49, 52, and the like provided in the intermediate layer 3, thereby also improving the heat insulating performance.

The double window, the double window inner window and the double window forming method of the present invention are not limited to the case where the outer window 1 and the inner window 2 are simultaneously provided on the newly built building, even if an existing single window frame is installed (outside The window of the window 1), and later the addition of the inner window 2, the case of forming a double window can also be applied. By using existing external windows, the cost is reduced.

The invention is not limited to the embodiments described above. The shape of the outer window and the inner window is arbitrary, and is not limited to a window in which the track is staggered, and may be a fixed window or a casement window. The venting of the outer and inner windows does not necessarily have to The upper frame is provided by means of an opening or the like. For example, a gap between the upper frame and the upper frame may be set as a venting portion, and air flows from the slit into the escaping person. The venting portion of the outer window may also be disposed in a stile or a lower frame. The impedance portion that imparts impedance to the flow of air may be provided at any of the vent portions or may be provided at the vent portion of the outer window. In addition, as the impedance portion, in addition to a porous material such as glass wool or urethane foam, a porous panel such as aluminum or a serrated blade in which the opposing faces in the vent portion are alternately protruded may be used.
