Abstract

(57) [Abstract] [PROBLEMS] To enable a comfortable drive by alleviating damage caused by an increase in temperature inside the vehicle by the sun while driving and parking the vehicle. SOLUTION: A cylindrical lid 5 is attached to a main body 1 provided with a ventilation hole 4.
The ventilation fan 6 in which the blades 7b are directly connected to the small motor 7a is provided inside the ventilation hole 4, and the ventilation fan 6 can be operated by a power source composed of a solar cell.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an in-vehicle ventilation device for a vehicle, which prevents the temperature rise in the parked vehicle by ventilation.

[0002]

[Prior art]

 While driving in a car, you can enjoy driving lively by adjusting the temperature to a suitable level with equipment such as an air conditioner. If you leave the car after driving and you leave it parked, it may be stolen if you leave it open, so normally the window is closed, so the temperature inside the car rises above the expected temperature while the sun shines on it. At present, the corresponding equipment is neither equipped nor sold in the car.

[0003]

[Problems to be solved by the device]

 In this way, the temperature rise inside the car becomes remarkable when the sun irradiates, especially in summer, when the temperature rises above 50 ° C, the life of the infant lying in the car is lost, and the precision equipment and I was very inconvenient in using the car because the decoration could not be protected and it could malfunction or peel off, or the beginning of the drive could become uncomfortable due to the heat, leading to an accident.

[0004]

[Means for Solving the Problems]

 The present invention eliminates such inconvenience, and provides an in-vehicle ventilation device for an automobile that can ventilate the inside of the vehicle automatically or manually during parking to prevent the temperature rise inside the vehicle. At the other end of the main body, which has a vent hole and a discharge port at one end, a cylindrical lid with a filter is provided to project a flange, and a ventilation fan that directly connects the blade to a small motor is installed inside the vent hole. It is equipped with a solar cell power source installed at an appropriate position on the vehicle to enable the ventilation fan to operate manually or automatically.

[0005]

[Action]

 When using it, attach it to the upper side of the rear side of the windowpane with the outlets on the outside. By operating a switch that can detect the temperature inside the vehicle and operates at a set temperature and operates automatically or manually, when the temperature exceeds the set temperature, the ventilation fan is activated to ventilate the inside of the vehicle and prevent the temperature from rising.

[0006]

[Embodiment]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 denotes a main body in which a cylindrical tubular body 2 is provided at one end with a rectangular parallelepiped emitter 3 having a circular one end, and an L-shaped ventilation hole 4 is bored and an outlet 4a is provided on the lower surface of the emitter 3. It is provided. Reference numeral 5 denotes a cylindrical lid body. A thread is provided on one outer periphery of the lid 5, and an annular flange 5a is projectingly provided on the other end of the lid. Reference numeral 6 denotes a ventilation fan in which blades 7b are directly connected to a small motor 7a, and the blades 7 are provided in the ventilation holes 4 with the attachment member 8 on the discharge port 4a side. A circular filter 9 is provided on the lid 5 by a magnet 10 provided on the opposite side of the lid 5 from the thread. Reference numeral 11 denotes a rectangular filter, which is provided at the emission port 4a by a magnet 12 provided at the emission port 4a. Reference numeral 13 is a power source composed of a polycrystalline silicon solar cell, and is connected to the small motor 6 through a switch (not shown) provided near the lower position of the front or rear glass.

[0007] In use, the mounting location is such that the radiator 3 is mounted on both sides of the upper rear portion of the side window glass. When the switch is turned on, the ventilation fan 6 is turned by the power source 13 to ventilate the inside of the vehicle. A small sealed lead acid battery may be used if necessary. Also, a switch that can be switched between automatic and manual may be used, and automatic ventilation at a set temperature may be performed in combination with a sensor. If it is not used in winter, etc., set a magnetic cover on the filter to prevent noise and cold air from entering the vehicle.

[0008]

[Effect of the invention]

 As described above, according to the present invention, since a ventilation fan operated by a small motor is provided in the upper rear part of the window glass of an automobile and the inside of the vehicle is ventilated by a power source such as a solar cell, the solar cell uses a multi-actuation. However, it does not require charging and costs no money, safety measures to protect life, prevention of malfunction of various precision equipment or protection of decoration, elimination of discomfort due to heat and bad smell when riding and parking of vehicles It has the effect of preventing theft and is a very good idea in practical use.
