Description

[Detailed description of the invention] The present invention relates to a ventilation system for buildings such as sunrooms attached to the outer walls of houses or greenhouses used for gardening. Concerning improvements in ventilation equipment that also prevented this.

Sunrooms etc. are made of a frame made of extruded material such as aluminum with a transparent plate such as glass attached to it.
Although it aims to improve daylight and temperature collection, it has the disadvantage that, for example, when the room is closed during the winter, exhaust gas generated from the indoor heating device accumulates and poses a health problem. For this reason, sunrooms equipped with ventilation devices as shown in FIGS. 1 and 2 have been developed. That is, in these figures, 1 is an outer wall of a house, and 2 is an upper frame horizontally fixed to this outer wall. A roof consisting of an outdoor horizontal frame 3, an indoor horizontal frame 4, a vertical frame 5, and a translucent plate 6 such as a glass plate or a plastic plate fitted between these frames is attached to this upper frame body 2. Furthermore, outdoor side pillars 7, indoor side pillars 8, etc. are erected below this roof.
A sunroom was formed. In this case, the ventilation system is formed by attaching the indoor horizontal frame 4 below the upper frame 2 with a space between them, and as shown in FIG. It is formed into a letter-shaped channel cross-sectional shape and is attached with a gap from the skirt plate 9 of the upper frame body 2,
As a result, a maze-like ventilation channel 10 is formed between these frames, and a part of the indoor horizontal frame 4 is cut out to form an air inlet/outlet 1 communicating with the channel 10.
1 was opened towards the interior. A ventilation blower 12 is disposed opposite the air inlet/outlet 11, and the rotation of the fan of this blower forcibly blows indoor air to the outside for ventilation. Therefore, such ventilation equipment sends exhaust gas from the heating equipment outside,
Although it is possible to keep the indoor air clean, since the air inlet and outlet and ventilation flow path of this ventilation system are always open, insects may enter the room through these. This has the disadvantage that cold air from outside enters the room, making it impossible to achieve the purpose of the sunroom.

The present invention eliminates these conventional drawbacks by making the air inlet and outlet openable and closable, and by appropriately installing an insect screen.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIG. In addition, in the illustrated embodiment,
The same parts as in the conventional example are given the same reference numerals, and the details thereof will be omitted.

In FIG. 3, the upper frame 2 fixed to the outer wall 1 of the house is formed of a ridge timber 21 and a skirt plate 9 hooked to the upper part of the ridge timber 21. The indoor horizontal frame 30, which is attached at a predetermined interval to the indoor side frame 30, has a lower hook portion 31 hooked to the ridge timber 21 so as to be rotatably engaged. In this case, a fitting groove 32 is formed at the outdoor end of the horizontal frame 30, and the transparent plate 6 is held in this fitting groove 32 via the tight material 22, and the fitting groove 32 is formed at the indoor end as appropriate. Openings 33 of a predetermined width are formed at intervals, and air inlets and outlets 35 are also formed on the lower end surface toward the interior of the room.
are opened, and these communicate with the ventilation channel 10. Furthermore, a longitudinal cavity 34 is formed in the center of the indoor horizontal frame 30, and a rotary or fan type blower 12 is disposed within this cavity 34 to ventilate the indoor air. It is designed to be forcibly sent out into the passageway 10.

In the indoor horizontal frame 30 formed in this way, the opening 33 that communicates with the ventilation passage 10
An insect-proof net 41 is stretched over the area. This insect net 4
1 is formed by intertwining metal wires or plastic wires vertically and horizontally, thereby creating a ventilation flow path 1.
Even if insects or the like enter the room, the insect screen 41 prevents them from entering the room. Furthermore, an opening/closing lid 43 is attached to the air inlet/outlet 35 on the indoor side. This opening/closing lid 43 is swingably attached to the indoor horizontal frame 30 via a hinge 44, and this swinging allows the air inlet/outlet 35 to be adjusted to open or close. Further, a magnet 45 is fixedly attached to the horizontal frame 30 and the opening/closing lid 43, and the magnet 45
The opening/closing lid 43 is closed by the
A receiving metal fitting 46 is hung from the lower surface of the opening/closing lid 43, and a hooking rod is hung thereon when the lid 43 is opened. Therefore, when opening this opening/closing lid 43, use the receiving metal fitting 4.
This is possible by pulling the lid 43 downward, which opens the air inlet/outlet 35 that communicates with the ventilation flow path 10 and enables indoor ventilation. The air inlet/outlet 35 is blocked by closing the air inlet/outlet 35.

4 to 6 show another embodiment of the present invention, in which the same parts as in the previous embodiment are given the same reference numerals, but in this embodiment, the insect screen 41 has an opening. It is not attached to the air inlet/outlet 33 but is stretched over the lower surface of the air inlet/outlet 35. In this case, the insect screen 41 is stretched between the mesh frames 47 with its ends wrapped around the mesh frame 47, and the insect screen 41 is stretched between the indoor horizontal frames 3
C-shaped mounting brackets 36, 36 are screwed to the bottom surface of the 0, and cushion bodies 37, 37 made of rubber or the like inserted into the mounting brackets 36, 36 press the mesh frame 41 from both sides, An insect screen 41 is stretched over the air inlet/outlet 35. As shown in FIG. 5, 38 is a connecting plate screwed to the horizontal frame 30 in order to adjust the opening width of the opening 33. Therefore,
In this embodiment, the insect repellent net 41 can be easily removed by opening the opening/closing lid 43, which allows the insect repellent net 41 to be cleaned or replaced, and also has the effect that the net will not become clogged.

Note that the present invention is not limited to the above-mentioned embodiments, and various modifications are possible. For example, the opening/closing lid may be formed to be slidable from side to side to open and close, or a magnet may be used to close the opening/closing lid. Instead, a spring or screw may be used instead. Furthermore, it can be used not only for sunrooms but also for gardening greenhouses and the like.

As described above, according to the present invention, it is possible to provide a ventilation system for a building such as a sunroom, which allows adjustment of ventilation and prevents insects from entering. Furthermore, since the indoor horizontal frame is rotatably attached to the ridge timber, the angle of the roof can be changed freely. Furthermore, the blower is installed in a location where it is not directly exposed to rainwater, so it is less likely to break down, and in the event of a breakdown or maintenance, it can be easily repaired or replaced using the downward facing air inlet and outlet.
