BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator using a bay window in a room having a bay window.

[0002]

2. Description of the Related Art Sufficient ventilation in a room is important to create a comfortable living environment, and conventionally, forced ventilation using a ventilation fan or the like is performed in a space where natural ventilation such as a ventilation window is insufficient. . However, if you try to perform forced ventilation in each individual room, regardless of whether you have ducts around the building like an air conditioning facility in a building, the air blower may be exposed indoors or outdoors, which may damage the exterior appearance and design of the building. .

Further, since the air in the room is exhausted by a normal ventilation fan or the like, there is a problem that the outside air enters the room through the gap at the lower part of the door. That is, at the time of heating, warm air that stays in the upper part of the room is discharged to the outside by the ventilation fan and at the same time, cool air enters the lower part of the room, and it is not possible to maintain the indoor heating state where head cold foot heat is ideal. Invades the living area of the and deteriorates the cooling efficiency.

Furthermore, even though forced ventilation is used, since the ability to actively stir and flow indoor air is weak, it is not possible to eliminate the situation in which air stagnates near the window, and the dew condensation easily occurs at these points. is there.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a ventilation device in which a blower device is inconspicuous and has a function of preventing dew condensation.

[0006]

[Means for Solving the Problems] A room provided with a bay window. A blower is installed in the attic space of the bay window, and an outlet is provided on the top plate. The blowout port is formed on the indoor side of the bay window shoji at a position close to the shoji. Connect the suction port of the blower to the outside air intake port, and connect the discharge port to the outlet port.

1 shows a part of a room 2 with a bay window 1,
Reference numeral 3 is a wall. The bay window 1 is composed of a roof portion 4, a main body portion 5 and a lower cover portion 6, and is attached to an opening portion 7 of the wall 3.

The roof portion 4 is provided with an attic space 9 between the roof portion 4 and the top plate 8 of the main body portion 5, and a blower 10 is housed therein. The blower device 10 is composed of a blower box 11, a blower 12, a damper-type switching valve 13, and an outside air intake port 14 (plurality) formed in the eaves portion of the roof 4 on the outdoor side.

The suction port 15 of the blower 12 is a duct 16
Is connected to the outside air intake 14 by
The outlet 17 of the blower 12 is connected to the center of a duct portion 18 formed between the blower box 11 and the top plate 8. The suction port 15, the duct 16, and the discharge port 17 are formed by the blower box 11 as part of its structure. Reference numeral 19 in the blower box 11 is a baffle plate for preventing blowing from the outside air intake port 14 when a strong wind occurs.

The main body 5 has a frame structure (only upper and lower frames on the outdoor side are shown) assembled with a frame member 20 of extruded material, and a ceiling plate 8 and a floor plate 21 and a shoji (outdoor window) for partitioning the outdoor from the indoor. The glass 22 is fitted as a shoji (shoji) and is attached, and the structure is the same as that of a normal bay window as a whole, and this part is attached to the building frame. Then, at a location on the indoor side close to the glass 22 of the top plate 8, outlets 23 (plural) toward the indoor side surface of the glass 22 are provided.
Is formed, and discharge openings 24 (plurality) that can be opened and closed are formed at the position of the floor plate 21 corresponding thereto. In addition,
A hole 25 is formed in the cover portion 6, so that the discharge port 24 communicates with the outside.

The duct portion 18 is formed in the air supply port 26 by opening at the indoor end where the indoor side end is flush with the indoor side surface of the wall 3. That is, the air supply port 26 is provided in the upper part on the indoor side of the room having the bay window 1.

On the other hand, the outdoor side end is connected to the outlet 23 and is then closed by a plate member constituting the blower box 11. A variable airflow direction louver 28 having louver blades 27 that are horizontally arranged and each of which has an adjustable opening angle is attached to the air supply port 26.

The damper type switching valve 13 is arranged at the position of the discharge port 17 and operates a lever 29 penetrating the top plate 8 to blow the air from the blower 12 on the blowout port 23 side (A). ) Or the direction toward the air supply port 26 side (B). However, in this embodiment, the outlet 23 side is not completely closed even when switching to the air supply port 26 side.

The blower 12 is similar to an ordinary ventilation fan, and can be turned on and off by a switch S in the room. When the fan is turned on, the fan is always driven and rotated in one direction, and the outside air is always sucked through the suction port 15. It is designed to deliver in the direction of the discharge port 17.

At the lower part of the inner surface of the wall 3, there are formed a plurality of openable and exhaustable exhaust ports 30 communicating with the outside. Reference numeral 31 is the floor of the room 2.

With the lever 29 in the (A) position, the switching valve 13
When the switch S is turned on, the blower 12 is driven and the outside air is taken in from the outside air intake 14, and the duct part 1 is discharged from the discharge port 17 of the blower 12.
8. It is supplied to the inside of the glass 22 through the outlet 23. On the other hand, as a result, the atmospheric pressure in the room rises a little, and the room air flows out through the gap at the lower part of the door to ventilate the room.

In this case, the outside air is not directly introduced into the room but fills the space inside the exit window 1 and then flows out into the interior space, that is, is buffered in the exit window space before being introduced into the room. Residents rarely feel the outside temperature (cold / warm). Further, during ventilation, the atmospheric pressure in the room rises slightly as described above, so that outside air does not enter through the lower part of the door or the like.

Further, the blow-out port 23 is made of glass 22.
Since a part of the flow of the air supplied from the outlet 23 is blown onto the surface of the glass 22 and then becomes a constant curtain-like flow that descends along the surface, the dew condensation on the glass 22 occurs. Prevent the occurrence of. In this case, as in the embodiment, the floor plate 21 of the bay window 1 is provided with the discharge port 24, and when the discharge port 24 is opened, the above-mentioned constant flow is stabilized as a layer, and the effect of preventing dew condensation is enhanced. Further, when the dew condensation that has once occurred is eliminated, if the discharge port 24 is opened, the evaporated water will not be brought into the indoor space.

When forced ventilation and agitation of room air are required, the lever 19 is operated to the air supply side (B) to switch the switching valve 1.
3 is also opened to the air supply port 26 side to supply the outside air from the outside air intake port 14 to the room through the air supply port 26. Then, similarly to the above, the room air pressure rises slightly, so that the air in the room is pushed out of the room through the gap at the lower part of the door or the like for ventilation.

At this time, what is pushed out is the air in the lower part of the room, and the warm air in the upper part of the room is less likely to be lost at the time of heating. On the other hand, the air in the room is forced by the air blown from the air supply port 26. The temperature difference between the upper part and the lower part of the room is eliminated. This situation is further promoted when the exhaust port 30 provided at the lower portion of the indoor side wall surface is left open. Further, if the variable louver 28 is directed upward as shown by the solid line in FIG. 1, the wind direction from the air supply port 26 is upward, and the indoor air is in a mixed state in which the air mass in the upper part is pushed downward, and during heating. Ventilation reduces the rate of warm air loss.

During cooling, ventilation is performed with the wind direction of the variable louver 28 facing downward as shown by the chain line. Then,
Outside air is supplied into the room at a steep angle from above, and ventilation is performed in a manner that pushes cold air in the lower part of the room upward. Therefore, the temperature difference between the upper part and the lower part of the room is quickly eliminated, and the proportion of cold air lost from the gap under the door is reduced.

Even if the switching valve 13 is opened to the air supply port 26 side, the outlet port 23 side is not completely closed. Therefore, when the supply port 26 is used to mix room air. Also, the outside air is flowing along the surface of the glass 22 to prevent the occurrence of dew condensation. The configuration in which the exhaust port 24 and the exhaust port 30 can be closed is for opening and closing as needed at the time of ventilation and for preventing blowing of outside air as described above.

FIG. 2 shows another embodiment in which the blower box 11 is simply formed. That is, the box has a suction port 15 and a discharge port 1 for the blower 22.
The plate-like structure is provided with only the portion 33 forming the duct portion 18 between the portion 32 forming the 7 and the top plate 8. Regarding the other parts, there is no particular difference from the case of the first embodiment. In this embodiment, the outside air is once drawn into the attic space 9 from the outside air intake port 24 by the blower 12 and then sent into the room. It is convenient when the attic space 9 is small.

Further, as another embodiment, the operating position of the lever 29 can be set in two steps other than the two positions (A) and (B) so as to be set in several stages, and the condition of the air in the room and dew condensation can be set. The amount of air from the air supply port 26 and the air outlet 23 can be finely adjusted in consideration of the amount of the air, and the exhaust port 24 can be switched between the outdoor and the indoor to communicate with each other, and the exhaust port 30 can be indoors. May communicate with other spaces.

[0025]

[Advantage of the Invention] The blower is not conspicuous, and the forced ventilation can be performed in a good appearance, and dew condensation does not occur on the bay window shoji. In addition, the condensation that has already occurred disappears promptly. The loss of warm air and cold air due to ventilation during heating and cooling is small, and heating / cooling efficiency is less likely to decrease. The outside air taken in is buffered in the space on the indoor side of the bay window, and the outside air temperature is rarely felt indoors. At the same time as taking in the outside air, the indoor air can be mixed, and a comfortable indoor environment can be created by eliminating the temperature difference between the inside and outside of the room.
