Description

[Detailed Description of the Invention] This invention relates to a deodorizing machine for automobiles, and is designed to fully demonstrate its deodorizing function, especially during the daytime when deodorizing is necessary.

Traditionally, as a method to remove odors from inside a car,
The most common methods were adsorption with activated carbon or masking odors with aromatics, but since the deodorizing effect of activated carbon or aromatics is almost constant, the deodorizing effect is often weak or vice versa. The problem was that it was too strong. There are also known systems in which a fan is used to forcibly flow the air that carries the fragrance, but this requires wiring inside the car and the need to drive the fan. Stopping had to be controlled manually, which was complicated.

However, this idea installed a solar cell diagonally on the back side of the case, and used a fan driven by the electromotive force of the solar cell to flow the air inside the case. Because of the arrangement of the parts, the fan automatically rotates and fully exerts its deodorizing function during the day when deodorization is especially necessary, that is, when the temperature inside the vehicle increases, and this eliminates the problems of the conventional method. They succeeded in correcting this.

That is, to explain this invention with reference to an embodiment, in a case 3 consisting of a box body 1 with an open front and a cover plate 2 detachably attached to the opening, ventilation grooves 4, 4 are provided in the cover plate 2. On the other hand, ventilation grooves 7, 7 are also formed in the bottom plate 6 of the box body 1 to serve as an air intake port 8. The rear wall 9 of the box body 1 is configured by connecting a vertical wall 10 and an inclined wall 11,
A solar cell 13 is pasted in a recess 12 formed in the center of the slanted wall 11, and output lead wires 14, 14 of the solar cell 13 are introduced into the box 1. A solar cell motor 16 is housed in the center of the box 1 via a support 15 provided on the bottom plate 6, and the output lead wires 14, 14 are connected to the solar cell motor 16.
Connect to.

A fan 18 is fixed to the rotating shaft 17 of the solar cell motor 16, and the fan 18 is attached to the cover plate 2.
When the fan 18 rotates, the air inside the case 3 is exhausted to the outside from the air outlet 5 of the cover plate 2, and the outside air is introduced into the case from the air intake port 8 of the bottom plate 6. Let's make it easier. A breathable urethane sheet 21 impregnated with activated carbon particles 20 is removably attached to the inner surface of the lid plate 2 via retaining bands 19, 19, and the urethane sheet 21 almost covers the air outlet 5. do it like this.

The automobile deodorizer of the above embodiment is used by being installed, for example, on a shelf formed inside the rear window of an automobile (passenger car). The solar cell 13 is of course opposed to the glass of the rear window so that it can receive sunlight.

When sunlight enters through the rear window during the daytime, the solar cell 13 receives a portion of the sunlight, and the electromotive force of the solar cell 13 drives the solar cell motor 16. Therefore, the fan 18 rotates as the solar cell 16 is driven, and the air inside the case 3 is discharged from the air outlet 5 through the urethane sheet 21, and the air inside the car is forced into the case 3 through the air intake port 8. The air is taken in and eventually circulates as shown by arrows 22, 22. During this air circulation, the odor contained in the air is adsorbed by the activated carbon particles 20 impregnated into the urethane sheet 21, so that the odor inside the automobile is deodorized.

In addition, as a means for arranging the activated carbon particles 20 at the air outlet 5, a urethane sheet 2 is used as in the embodiment.
In addition to using method 1, there is a method of storing the activated carbon particles 20 in a flat bag with air permeability, a method of attaching the activated carbon particles 20 to a net-like object, and a method of using porous paper felt made of activated carbon fiber. Conceivable. Furthermore, it is also possible to use other adsorbents instead of activated carbon particles.

However, the time when it is necessary to eliminate odors inside a car is during the daytime when cars are frequently used, and moreover, during the daytime when the temperature inside the car increases. Therefore, according to the embodiment, when sunlight enters through the rear window during the daytime, the fan 18 automatically rotates and actively causes the air inside the vehicle to pass through the urethane sheet 21. The deodorizing machine can maximize the deodorizing effect when odor is required.

In addition to the activated carbon particles 20, an aromatic agent having a masking effect against foreign odors can also be used as a member for deodorizing odors in the air. To use an air freshener, place the container 24 containing the solid air freshener 23 on the bottom plate 6 as shown in FIG.
8 rotates, the aroma dispersed from the solid aromatic agent 23 may be mixed into the air discharged from the air outlet 5.

The adsorption effect of the activated carbon particles 20 decreases,
When the solid fragrance 23 is exhausted, the lid plate 2 can be removed from the box body 1 and replaced with a new one.

As explained above, according to this invention, during the daytime when the deodorizing function is most needed, the fan is rotated via the motor by the electromotive force of the solar cell and the air inside the car is circulated. This has the effect of providing a deodorizing machine in which the function of the odor member can be fully demonstrated when necessary. In addition, the device can be installed in the interior of a car simply by placing it on a rear shelf, for example, and no wiring is required, making it easy to use.

Incidentally, activated carbon particles and an aromatic agent are illustrated as examples of the deodorizing member, but it goes without saying that a deodorizing agent that decomposes odor substances through chemical change can also be used.
