JPS62261520A - Ventilator for car interior - Google Patents

Abstract

PURPOSE:To maintain the comfortable state in the car interior by installing a solar battery onto the ceiling of a vehicle and a ventilator which is electrically connected with the solar battery and forming a ventilating hole onto the floor surface and operating the ventilator by utilizing the solar energy, thus carrying out the ventilation through the ventilating hole. CONSTITUTION:A solar battery 2 is installed onto the upper part of a ceiling 4 in a vehicle 1, and connected with a ventilator 3 through an electrical cord 12 and a switch 13. A ventilating hole 6 for taking-in the cold air 7 outside the vehicle is opened onto the floor surface of the vehicle 1. If the switch 13 is turned-ON when the vehicle 1 is in parking, the solar light 8 irradiates onto the solar battery 2, and the electricity generated in the solar battery 2 is introduced into the ventilator 3, and the blowing fan of the ventilator 3 revolves. Therefore, the hot air 5 in the car interior 14 is discharged outside the vehicle, and the cold air 7 under the floor surface outside the vehicle is introduced into the car interior 14 from the ventilating hole 16, and the car interior 14 can be comfortably cooled.

Description

[Detailed Description of the Invention] The present invention is intended to prevent the temperature inside the vehicle from becoming abnormally high when the vehicle is parked in a place exposed to direct sunlight in the summer. This invention relates to a vehicle interior ventilation system.

[Industrial application field]

Ventilation of the interior of vehicles such as automobiles.

[Conventional technology]

Conventional cars have K to make driving in the summer more comfortable.

A cooler is installed, and while the vehicle is running, cold air is constantly blown out through the cooler, lowering the interior temperature and creating a comfortable environment. The cooler is powered by more power than the car's carrot, so when the engine is stopped, the cooler will not operate.

[Problem that the invention seeks to solve]

When parking a car in an environment exposed to direct sunlight in the summer,
I usually shut off the engine, close all windows, and lock the car. In addition, cars have wide glass windows to provide a wide field of view and comfort, and the ceiling and other parts are all made of iron, making it extremely easy for heat to transfer. Under these conditions, when exposed to direct sunlight, the temperature inside the vehicle continues to rise even more than in a greenhouse, and the interior of the vehicle is filled with high-temperature air. After parking your car for a long time under the scorching sun, when you try to get back into the car, you will find that the temperature inside the car, heated by the greenhouse effect, does not come down easily, and the situation is similar to that of a steam bath. In order to start the engine, ventilate the hot air in the room, and start the air conditioner, K has to stay in the same environment as being in a hot steam bath for a considerable amount of time, which is comfortable for people who use cars while driving. However, it was extremely uncomfortable to get on board after parking, and a better solution was needed.

Measures to Solve Problem C] Therefore, we installed solar cells on the upper surface of the ceiling of the passenger compartment, which is prone to direct sunlight, and used solar energy to rotate the ventilation system installed near the ceiling, allowing air to flow from the bottom of the floor. It sucks in cold air and exhausts the hot air near the ceiling using a ventilation fan.

[Effect]

Even if the engine is stopped while the car is parked, the energy received from the sun activates the ventilation system, constantly discharging high-temperature air to the outside and allowing cold air from below the floor to continuously flow into the room. It has an extremely remarkable action and effect that can keep you comfortable at all times.

〔Example〕

Further, to explain this with reference to an embodiment shown in the drawings, 1 is a car, 2 is a large battery, 3 is a ventilation system, 4 is a ceiling, 5 is heated air, and 6 is a floor surface such as a floor surface or the lower part of a side wall. 7 is the cold air under the floor, 8 is the sun, 9 is the ventilation hole opened near the .
10.11 is a window glass, 12 is an electrical cord from the solar cell to the ventilation system, and 13 is a switch. A solar cell 2 is attached to the upper part of the ceiling 4 and connected to a ventilation system 3 via an electric cord 12 and a switch 13. In addition, a ventilation hole 6 is opened on the floor surface to take in cold air 7. Turn on the switch 13 to lock the vehicle and put it in a parked state. The light from the sun 8 hits the solar cell 2, and the electricity generated by the solar cell 2 passes through the electrical cord 12.
Passing through the switch 13, 'It& air is communicated to the ventilation device 3, and the fan of the ventilation device 3 starts rotating. The ventilation device 3 is
While the heated air 5 is discharged to the outside of the vehicle, the cold air 7 below the floor is sucked in through the ventilation holes 6, and the cold air continuously flows into the passenger compartment 14. You can park your car in a comfortable condition.

Therefore, the ventilation hole 6 is configured to be openable and closable in order to cope with seasonal changes. Note that the reference numeral 15 is the ground.

〔Effect of the invention〕

As mentioned above, the present invention can be used even when the engine is stopped while parked.
The energy received from the sun activates the ventilation system, constantly discharging high-temperature air to the outside, and allowing cold air from below the floor to continuously flow into the room, making it extremely effective to keep the room comfortable at all times. It has a certain action and effect.
