Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial application field The present invention relates to windows installed in window openings of buildings, and is intended to improve the living environment near the window by reducing heat radiation from the window. , relating to windows that allow for natural ventilation when necessary.

Conventional Technology Many modern buildings have been designed to improve their thermal insulation to save energy for heating in the winter and cooling in the summer. It is relatively easy to measure the improvement of the thermal insulation properties of walls, but since windows are made of glass to let in sunlight, it is difficult to measure the thermal insulation properties of ordinary windows. Therefore, in order to reduce the waste of air-conditioning energy caused by windows, it is necessary to devise measures for the windows themselves. The most advanced known method for this purpose is the JP-A-59-
No. 112140 is mentioned. This window has a fan installed in the upper frame member of the double-panel window, and the air inside the room is exhausted from the bottom through the space of the double-pane window to the outside by the fan.

This uses indoor air to actively cool the indoor glass, which is heated by the sun's radiant heat, improving the thermal environment near the window.
This also measures the exhaust of indoor air to the outdoors.

Problems to be solved by the invention In the above-mentioned conventional example, the glass on the indoor side that is heated by solar heat is cooled using the exhaust air from the room, improving the thermal environment near the window, and thereby saving air conditioning energy. Consumption can be reduced.

However, during the intermediate seasons such as spring and autumn, it would be preferable to let fresh air into the room by natural wind without using air conditioning, but the conventional windows that improve the thermal environment near the windows do not have the same effect. I couldn't do something like that.

The present invention was made with the aim of solving such problems.

[Structure of the invention] Means for solving the problem As shown in FIG. It is made up of a small window 5. Both are double-glazed windows consisting of two inner and outer glasses 6 to 9, with spaces 10 and 11 formed between them. The horizontal frame 3 is provided with a vent 13 for connecting both spaces. Furthermore, the inner and outer glass windows 8 and 9 of the small window are respectively incorporated into shoji screens 8' and 9', so that these shoji screens can be simultaneously opened by operating the shoji on the indoor side.

Exhaust port 17 on the outdoor side of the upper frame member 15 of the main window 4
is formed, and an air intake port 18 is formed on the lower indoor side.

Direct entry of heat rays into the room is reduced by arranging a blind 14 in the space 10, by using heat ray absorbing glass for each glass, or by covering the glass with a heat absorbing film.

Fan 1 is used to exhaust indoor air to the outdoors.
6 is generally provided, but it is also possible to use the blowing pressure of the air conditioning equipment to exhaust the air without using a fan.

Effect Even if the sun's heat is prevented from directly entering the room using the blind 14 or the like, it cannot prevent the indoor glass itself from being heated by the sun's heat. In the case of normal double-glazed windows, heating of the glass causes thermal radiation, making the area near the window hotter and making the living environment worse. In the case of the present invention, cool indoor air enters the space 10 from the intake port 18 due to the fan 16 or air conditioning pressure, and is exhausted to the outside from the exhaust port 17 through this space, so that the temperature of the shoji 6 on the indoor side is approximately controlled. The temperature can be brought close to indoor temperature. Therefore, thermal radiation from the window is alleviated. Furthermore, since the air passing through the space 10 collects and eliminates the heat just before it enters the room, for example the solar heat absorbed by the blind when the blind 14 is installed, the heat load is significantly improved. Therefore, the living environment near the window is improved and at the same time it helps to save air conditioning energy.

If you simply need ventilation through natural ventilation of outside air, open the indoor shoji 8' of the small window 5.
In the present invention, as described above, the shoji 9' on the outside side of the room is also opened simultaneously in conjunction with the shoji 8', so that natural ventilation without using the fan 16 is possible through this small window. Needless to say, forced ventilation using the fan 16 can be performed whenever necessary.

Embodiment FIG. 2 is a front view of an embodiment of the present invention seen from the indoor side, in which an upper frame 21, a lower frame 22, and a vertical frame 23 are attached to the window opening, and the upper frame 21 and the lower frame 2 are attached to the window opening.
A horizontal frame 24 is attached between the two. A main window 25 is formed between the upper frame 21 and the horizontal frame 24, and a small window 26 is formed between the horizontal frame 24 and the lower frame 22. As shown in the figure, the height of the small window 26 is lower than that of the main window 25. Both the main window 25 and the small window 26 are double-glazed windows made up of two shoji screens inside and outside. A fan 28 is attached to the internal space of the frame member 27 above this main window. The internal structure of this window will be explained below.

As shown in FIG. 3, the frame member 27 is provided with a partition wall 32 between an indoor wall 30 and an outdoor wall 31, and divides the inside of the frame member 27 into an upward flow path 33 and a downward flow path 34. The fan 28 is installed on top of the fan 28. An opening 35 with a length comparable to the length of the fan is formed in the part of the partition wall 32 at the outlet of the fan 28, and an opening 35 is formed with a length comparable to the length of the fan.

The upward flow path 33 is connected to the glass 36 of the main window 25.
a, 37a, which is connected to a space 38 formed between the indoor shoji 36 and the outdoor shoji 37. On the other hand, the downward flow path 34 is connected to an exhaust port 39 formed at the lower end of the outdoor wall 31. Therefore,
The space 38 is connected to an exhaust port 39 via an upward passage 33, an opening 35, and a downward passage 34. In this embodiment, since the exhaust port 39 is always open, there is a risk that rainwater may infiltrate from the exhaust port 39 into the space 38 and further into the room. Preventive measures are in place.

Raindrop blocking members 41 and 42 having a triangular cross section are alternately arranged on the partition wall 32 of the downward flow path 34 and the outdoor wall 31, and a damper 43 is provided on the outdoor wall 31. This damper 43 is a thin plate-shaped member, and is attached to the outdoor wall 31 so that it can rotate freely as shown in the figure, and comes into contact with the lower surface of the raindrop blocking material 41 when rotated, thereby closing the downward flow path 34. There is. The damper 43 is mounted on the tip of a protruding strip 44 protruding from the outdoor wall 31 and is inclined so as to be easily rotated. Moreover, the outdoor wall 3 on the back of this damper 43
1 has a wind pressure hole 45 formed therein, and an exhaust port 39
A wind direction changing member 46 is installed at the back of the damper 43 so that the wind pressure from the exhaust port 39 hits the damper 43, so when the positive outdoor wind pressure increases, the damper 43 immediately rotates to close the downward flow path 34. Prevents rainwater from penetrating inside. In addition, raindrops that enter the air flow until the damper 43 closes are removed from the raindrop prevention materials 41 and 42.
It hits and falls. Therefore, it is possible to reliably prevent rainwater from entering the interior.

A blind 47 is installed in the space 38. In this embodiment, this blind 47
Although the length is set to cover only the main window 25, it is of course possible to have a length to cover the small window 26 as well.

The indoor shoji 36 of the main window 25 can be opened as shown in FIG. is used as an air intake port 48. This air intake port 48 has a lid 49 that can be opened and closed freely.
is installed. This air intake is stile 3
6a, the horizontal frame 24 may be formed by other means such as making a hole.

This embodiment has a configuration in which indoor air is exhausted from the air intake port 48 through the space 38 and from the exhaust port 39 by the operation of the fan 28.

Note that 50 in the figure is a sound deadening box for reducing noise entering the room. Although it may simply be a box with holes on its surface, it is desirable to put sound absorbing material inside.

Next, the small window 26 will be explained. In this window, a shoji 51 fitted with glass on the indoor side opens inward at a hinge 52, and a shoji 53 fitted with glass on the outdoor side simultaneously opens outward at a hinge 54. The interlocking mechanism is as shown in FIG. 4, and utilizes a rotating lever 55 that rotates when the shoji 51 is opened.

This rotary lever 55 is rotatably attached to a stand 56 fixed to the inner wall of the vertical frame 23 with a pin 57, and one end thereof slides into a long hole 59 of a guide plate 58 fixed to a stile of the shoji 51. The other end is slidably attached to a long hole 61 of a guide plate 60 similarly fixed to a stile of the shoji 53. One end 59a of the elongated hole 59 is bent at a right angle,
Rotary lever 55 inserted into elongated hole 59 here
The shaft can be inserted and held in the open position.

Therefore, when the handle 61 shown in FIG. 3 is removed from the locking member 63 provided on the horizontal frame 24 and pulled forward, the shoji 51 rotates around the hinge 52, and the rotating lever 55 is rotated accordingly. Push the guide plate 60 with the other end to open the shoji 53.

As mentioned above, the small window 26 is a double-glazed window, and a space 63 is formed between the inner and outer shoji. Horizontal frame 24
is integrally molded as shown in the figure, and a hole 64 serving as a ventilation port is formed in the middle thereof to connect with the space 38 of the main window 25. An L-shaped member 65 installed inside the horizontal frame 24 is for preventing the inside from being seen through the hole 64. When the blind 47 does not reach the small window as in this embodiment, it is desirable to cover the glass of the shoji of the small window with a heat reflective film. Either internal or external is sufficient.

In this embodiment with the above configuration, the small window is closed and the fan 2
If 8 is operated, the temperature near the window can be lowered as explained in the section of the above-mentioned function, and the living environment near the window can be improved. Further, in this case, hot air generated within the small window is sucked through the hole 64 and exhausted to the outside. Therefore, it is possible to prevent deterioration of the thermal environment near the window caused by heating of the indoor glass in the small window. Furthermore, it does not require any special explanation that natural ventilation can be achieved by opening the small window 26.

FIG. 5 relates to another embodiment in which the horizontal frame is not integrated, but an indoor side horizontal frame 70 and an outdoor side horizontal frame 71.
The shoji 73 on the indoor side of the small window 72 and the shoji 74 on the outdoor side of the small window 72 are each hinged on the hinge 7.
5, they are attached to the respective horizontal frames 70, 71 so that their lower ends rotate in directions away from each other. The air intake port 76 in this embodiment is formed in the lower stile 77a of the shoji 77 of the main window. These have a space 78 formed therein as described above, and are connected to the space of the main window via a vent 79 formed between both horizontal frames. In this embodiment, the four-circumference frame body is also separated into two parts, one on the indoor side and one on the outdoor side, and connected to each other with a heat insulating material 80 interposed between them. By separating the inside and outside in this way, it is possible to reduce the transfer of heat from the frame material, etc. on the outdoor side to the indoor side. Therefore, the heat insulation properties can be improved.

FIG. 6 shows a mechanism for interlocking and opening the shoji on both sides of this small window. A shaft 82 is fixed to a lower stile 81 of a shoji 74 on the indoor side, and one end of an elongated plate-shaped arm 83 is rotatably attached to the shaft 82. Similarly, one end of a similar arm 85 is rotatably attached to the lower stile 84 of the shoji 75 on the outdoor side. The other ends of both arms are aligned and rotatably attached to a slider that is slidable in a sliding groove 87 fixed to the vertical frame 23. Therefore, the indoor shoji 7
4 is opened, the arm 83 is pulled, the slider is lowered, and the arm 85 is pushed to open the shoji 75 on the outside of the room.
To fix it in the open state, one end is rotatably attached to the vertical frame 23, and the other end is formed into a hook shape, and the hook-shaped tip of the stopper 88 is formed into a ring shape attached to the vertical frame of the shoji 74. This is done by placing it in the ring of the stopper 89.

[Effects of the invention] As described above, this invention has a structure in which indoor air is exhausted from the air intake to the outside through the space inside the double-paned window, which prevents solar heat from entering the room. can improve the thermal environment of Therefore, air conditioning energy can be saved.

In addition, the windows are separated into a main window and a small window, and the small windows can be left open inside and outside at the same time, allowing natural ventilation without using fans.

Furthermore, since the present invention connects the space provided in the small window with the space in the main window, the hot air generated in the small window can be released to the outside, thereby preventing the thermal environment from deteriorating due to the small window. be able to.
