[Problems to be solved by the invention]
However, if the ventilation window 91 is left open, particularly when the vehicle is running, the outdoor air blows strongly through the ventilation window 91 or rain enters, so that the wind and rain may fall within the room. There is a problem in that it may directly hit you and make you feel uncomfortable. By adjusting the degree of opening of the ventilation window 91 with the shutter mechanism 94, it is possible to adjust the amount of wind blowing or prevent rain from entering, but depending on the outdoor weather and the running speed of the car It had to be adjusted one by one, and it was troublesome.
[0005]
Also, when a car is parked and a person leaves the room, the ventilation window 91 is left open to prevent the room from becoming hot or to keep the room ventilated. Then, there is a problem that rain falls from the ventilation window 91 and the room gets wet.

[0026]
DETAILED DESCRIPTION OF THE INVENTION
1 to 4 show a first embodiment in which the present invention is embodied in a ventilator 1 used in an automobile as a vehicle having a room as a ventilated space. The ventilation device 1 includes a window mounting portion 2 that is detachably mounted between an upper frame 20 of an automobile window and a window glass 21, and a vent pipe 3 that is mounted outside the window of the window mounting portion 2. ing.
[0027]
The window mounting portion 2 is made of a flexible material (for example, soft resin, rubber, etc.). On the upper surface and the lower surface of the window mounting portion 2, a ridge 2a and a groove 2b extending in the length direction of the window mounting portion 2 are formed. In order to attach this window mounting portion 2 to the window of an automobile, as shown in FIGS. 2 (d) and 4, an upper edge of the window glass 21 is formed in a groove 20a formed on the lower surface of the upper frame 20 of the window of the automobile. Instead of the portion 21a, the protrusion 2a of the window mounting portion 2 is inserted. At the same time, the upper edge portion 21a of the window glass 21 is inserted into the concave groove 2b of the window mounting portion 2.
[0028]
The vent pipe 3 extends in a straight line in the substantially horizontal direction and in the front-rear direction of the automobile. The vent pipe 3 is provided with a vent pipe 5 through which outdoor air flows outside the ventilated space. The air duct 5 extends in a straight line in the air duct 3 in a substantially horizontal direction and in the front-rear direction of the automobile, and both ends of the air duct 5 open in the front-rear direction of the automobile. As a result, the air flowing in the front-rear direction of the automobile passes through the ventilation duct 5. The edge 5a of the opening of the ventilation duct 5 is formed so that the upper side protrudes relatively in the length direction of the ventilation duct 5 from the lower side. The color of the air pipe 3 is not particularly limited. For example, if the color is made transparent or the same color as the body of the automobile, it becomes inconspicuous and the influence on the appearance design of the automobile can be reduced.
[0029]
The vent pipe 5 is provided with a throat portion 6 formed in a shape in which a middle portion of the vent pipe 5 is narrowed. The throat portion 6 is formed such that the lower side portion of the inner peripheral surface of the ventilation duct 5 is curved in a convex shape. In this example, a substantially central portion in the length direction of the ventilation pipe 5 is employed as the middle part of the ventilation pipe 5.
[0030]
The window mounting part 2 is provided with an exhaust pipe line 7 that communicates the throat part 6 with the inside of a room as a ventilated space. The exhaust pipe 7 extends from a portion of the throat 6 where the vent pipe 5 is most narrowed in a direction perpendicular to the length of the vent pipe 5. The exhaust pipe 7 can be changed as shown in FIG. FIG. 4A shows a mode in which the exhaust pipe 7 is inclined so that the throat side is relatively lower than the room side. FIG. 2B shows a mode in which a middle portion 7a of the exhaust pipe 7 is projected upward. FIG. 2C shows a mode in which a check valve 8 is provided in the middle portion 7b of the exhaust pipe 7 to allow a flow exhausted from the room and prevent the reverse flow. Thus, by appropriately changing the exhaust pipe 7, it is possible to more reliably prevent the outdoor air or rain from being blown into the room.
[0031]
According to the ventilator 1 of the present invention configured as described above, the vent pipe 5 that allows outdoor air to flow and the middle part of the vent pipe 5 are formed in a narrowed shape. 2 and the exhaust pipe 7 that communicates the throat 6 with the inside of the room, as shown in FIG. 2 (a), one of the vent pipes 5 (in this example, FIG. The flow of air flowing into the ventilation duct 5 from the opening on the left side) is throttled at the throat 6 and the flow velocity of the flow is increased to lower the static pressure at the throat 6 and exhaust the air in the room. It can be sucked into the throat 6 through the pipe line 7 and discharged from the other opening of the vent pipe line 5 along with the air flow. Therefore, natural ventilation in the room can be realized using the wind force of the air flowing outside the room.
[0032]
For example, when the automobile is running, the air in the room is naturally discharged through the exhaust pipe 7 to the outside of the room by the air flowing outside the room, so that the room can be opened without opening a window or a sunroof. It is possible to ventilate the interior more effectively and prevent the temperature and humidity in the room from rising. In particular, a sudden temperature rise in the room can be prevented in summer. Moreover, outdoor air flows from the ventilator 1 and does not directly hit the people in the room, and rain does not enter the room, making the people in the room feel uncomfortable. Absent. In addition, even when the automobile is parked, if the outdoor wind flows into the vent pipe 3, the room is naturally ventilated, thereby preventing the temperature in the room from rising. it can. Moreover, it can also be used for discharge of chemical substances remaining in the room by attaching it to the window of the automobile before the sale after the manufacture of the automobile.
[0033]
The length of the vent pipe 5 is substantially horizontal, and the edge 5a of the opening of the vent pipe 5 is relatively longer on the upper side than on the lower side. Therefore, it is possible to make it difficult for rain, snow, and the like to enter the ventilation duct 5.
[0034]
Further, since the throat portion 6 is formed at the substantially center in the length direction of the vent pipe 5, the directionality in the length direction of the vent pipe 5 is eliminated as much as possible. Even if air flows in from the side, the ventilation effect can be achieved under substantially the same conditions.
[0035]
In addition, the vent pipe 5 has an opening in a substantially horizontal direction, and the throat portion 6 is formed such that the lower portion of the inner peripheral surface of the vent pipe 5 is curved in a convex shape. It is possible to make it easy for rain or snow that has entered the interior 5 to be discharged out of the air duct 5 along the inclination of the lower side of the inner peripheral surface. It is to be noted that the same effect can be obtained by forming the vent pipe 5 in a curved shape so that the middle part thereof projects upward.
[0036]
Moreover, in the ventilation apparatus 1 of this example, it is provided with the window attachment part 2 which can be attached to the upper frame 20 of a window, and while attaching the ventilation pipe 3 which has the ventilation duct 5 to the window outer side of this window attachment part 2, Since the exhaust pipe 7 is provided in the attachment portion 2 so as to communicate the throat portion 6 with the interior of the room, the attachment portion 2 can be easily attached to a window of a ready-made automobile.
