Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle interior ventilation system for preventing the interior of an automobile parked under blue sky from becoming hot.

[0002]

2. Description of the Related Art When an automobile is parked in the blue sky, windows are closed and doors are locked to prevent theft. However, when sunlight enters the closed interior of the vehicle, the temperature of the vehicle interior rises significantly. In particular, in the summer, even during a short period of blue sky parking, the interior of the vehicle becomes hot enough to burn when touching a seat or a steering wheel, and the car cannot be started immediately.

In this case, in order to prevent the temperature in the passenger compartment from rising, some automobiles are parked in the blue sky while the engine and the clutch are running, causing problems such as environmental pollution by exhaust gas and waste of gasoline. .

[0004] In order to solve this inconvenience, there have been proposed various automobile interior ventilators in which a motor-operated exhaust fan is provided in a vent communicating between the interior of the automobile and the exterior of the interior of the automobile, and is driven by a solar cell. Have been.

For example, Japanese Patent Application Laid-Open No. 7-40736 discloses a ventilation device which is mounted on a horizontal platform that separates a space inside a vehicle compartment from a space inside a trunk room, and discharges air inside the vehicle room into the trunk room. A solar cell that is incorporated into the same substrate as the ventilator and serves as a drive power supply for the ventilator, and includes a shutter device that controls power supply from the solar cell to the ventilator by opening and closing a light receiving surface of the solar cell, A vehicle equipped with a solar cell-driven ventilation device in which the driving of a shutter device is linked to a handbrake is described.

However, this configuration is not suitable for a user to retrofit a vehicle with a ventilation device.
This is because it is necessary to incorporate a switch for controlling the driving of the shutter device into the inside of the handbrake lever, or to form a communication hole for connecting the vehicle compartment and the trunk compartment to the horizontal base for mounting the ventilation device. It is.

Furthermore, in this configuration, the air discharged into the trunk compartment is discharged from the exhaust port provided in the vehicle in advance to the outside of the vehicle.
Even if the window glass is closed, it functions as an air vent so that the door can be easily closed. Therefore, without a certain degree of exhaust pressure, air cannot be exhausted from the exhaust port to the outside of the vehicle. Therefore, this ventilator cannot efficiently ventilate the passenger compartment.

[0008] In the ventilator described in Japanese Patent Application Laid-Open No. 9-95124, an exhaust fan is provided in a vent that communicates between the interior of the vehicle and the outside of the vehicle. The vent opens to the shelf board behind the rear seat in the vehicle compartment, and is connected to the vent at the bottom of the vehicle chassis through a duct. Further, solar cells are provided on the outer surface of the ceiling of the vehicle, the inside of the vehicle inside the rear window, and the like. Then, the electric power generated by the solar cell is accumulated in the electric storage device, and the electric power is supplied from the electric storage device to the exhaust fan by the operation of the temperature sensor arranged in the vehicle interior, thereby ventilating the interior of the vehicle interior.

However, in this configuration, it is troublesome to form an air vent in the shelf board and attach an exhaust fan to the air vent. Not suitable.
Moreover, since the ventilation holes are opened in the shelf board behind the rear seat, there is a drawback that the hot air drifting near the ceiling of the passenger compartment cannot be efficiently discharged.

[0010] Further, in any of the above-mentioned ventilators, the sunlight entering the vehicle compartment is directly received by the solar cell. It is questionable whether the ventilation effect can be obtained.
