Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ventilation system for an automobile having a forced ventilation means that can reduce the high temperature inside a car parked under the scorching sun.

Conventional technology When parking outdoors under the scorching sun during the summer, it is necessary to close the windows tightly to prevent the vehicle from being stolen. causing discomfort to passengers. Therefore, in the past, as seen in Japanese Patent Laid-Open No. 53-140731, a ventilation fan and a fan motor were built into the parking ventilation passage inside the vehicle. It is known that the vehicle operates on super-electric power and provides forced ventilation while the vehicle is parked.

Furthermore, conventionally known vehicles have a fan and fan motor installed in the ceiling or behind the seats in order to forcefully circulate the air inside the vehicle while driving.

In addition, Japanese Utility Model Application Publication No. 60-97615 discloses a device in which a ventilation casing is sandwiched between a window frame and a blower attached to the ventilation casing is operated by a solar battery to provide ventilation.

Problems that the invention aims to solve The configuration of Utility Model Application Publication No. 60-97615 uses a combination of a blower attached to the ventilation casing and a solar cell, and by simply sandwiching the ventilation casing between the window frame and the windshield, the inside of the car can be heated. Ventilation can be performed. However, there is a problem in that a single device cannot circulate or intake air inside the vehicle.

This invention can be easily used in existing vehicles without special equipment, and can be used independently for ventilation (or intake).
The object of the present invention is to provide a ventilation system for an automobile that can perform circulation.

Means for Solving the Problems The automotive ventilation system of the present invention includes a ventilation casing that communicates with the outside of the car and has two or more openings on the inside of the car, and an outer surface of the ventilation casing on the outside of the car. and a blower that is built into the inside of the ventilation casing and is driven by the electromotive force of the solar cell, and the ventilation casing is placed on the top surface of the ventilation casing above the vehicle door window frame. A convex portion that engages with the edge is provided, a recessed portion is provided on the lower surface into which the upper end of the window glass that moves up and down fits, and a shutter plate or periphery that slides along the inner circumferential surface of the inside part of the ventilation casing is provided. A cylinder with a bottom that rotates along the direction is provided, and by changing the position of the shutter plate or the cylinder with a bottom, the intake side passage and the discharge side passage of the blower are connected to the inside opening of the ventilation casing and the inside of the car. It was switched to a first state in which it is interposed between the outer openings and a second state in which the flow path between the discharge side passage and the opening on the outside of the vehicle is closed and the suction side passage and the discharge side passage are connected to the opening on the inside of the vehicle. It is characterized by

Effect According to this configuration, by simply changing the position of the shutter plate or bottomed cylindrical body attached to the inside of the ventilation casing, when the first state is selected, air intake or exhaust is performed by the electromotive force of the solar cell. I,
When the second state is selected, the air inside the vehicle is circulated.

The opening 15B is located at the same position as the opening 25B and is open, and the opening 15B is shifted from the opening 25B and is closed. As for the openings 14A and 14B, as shown in FIG. 3c, opening 14B is open and opening 14A is open.
is blocked. Therefore, in the suction state shown in FIG.
A and 25A are connected to the vehicle exterior chamber 12, and a discharge side passage 27 of the blower 16 is connected to the interior of the vehicle through openings 23 and 14B. The air flows like this.

Figures 4 and 5 are distances from the state in Figure 3, respectively.
The state is shown in which the shutter plate 19 is slid by L ₁ and L ₂ to switch to the interior circulation state and the exhaust state, and in FIGS. 2B and 4, the intake passage 26 of the blower 16 is It is connected to the interior of the vehicle, and the discharge side passage 27 is connected to the interior of the vehicle via the openings 23 and 14A. In FIG. 2c and FIG. 5, the intake side passage 26 is connected to the interior of the vehicle through the openings 22 and 13A, and the discharge side passage 27 is connected to the opening 25B and the inside of the vehicle.
It is connected to the outside of the vehicle via 5B.

FIG. 6 shows a second embodiment. In the first embodiment, the solar cell 17 was attached to the vertical surface of the ventilation casing 2, but as shown in FIG. By attaching the light to the light, the light-receiving area becomes wider and the light can be efficiently converted into electrical energy.
