Description

[Detailed Description of the Invention] This invention relates to an air cleaner for an automobile that removes contaminants, particularly cigarette smoke, from the interior of an automobile and supplies clean air to the interior of the automobile.

Recently, with the spread of car air conditioners, the interior of the car has been made more airtight, and as a result, air pollution inside the car has become a problem.

In particular, if you smoke in an air-conditioned car, the smoke will remain in the car for a considerable amount of time, which will have a negative impact on non-smokers.

Under these circumstances, there are currently various air purifiers on the market that have a dust collection unit and an activated carbon filter housed in the main body, and are effective in cleaning the air inside a car.

However, dust collection units and activated carbon filters have a limited lifespan and need to be replaced after a certain period of time.
Since the activated carbon filter is usually located in the center of the main body, it is important to simplify the work of attaching and detaching it.

This idea was made to solve the above problems.
An embodiment of this invention will be described below.

In Fig. 1, 1 is a resin main body having an opening 2 on the front surface and the front upper surface connected to the front surface, and 3 is a resin lid having an air suction port 4 on the front surface, and the opening is opened by the elastic action of the resin. It is attached to 2.

5 is a dust collection unit housed in the dust collection chamber A in the front part of the main body 1;
Reference numeral 6 indicates an installation part provided on the main body 1 to horizontally install the dust collection unit 5. Reference numeral 7 indicates a guide part 8, which is a notch groove inclined upwardly on the front surface of the main body 1, on both sides. A fan casing is integrally formed, 9 is a blower housed in a blower chamber B at the rear of the main body 1, 10 is an air outlet provided on the rear side of the main body, and 11 is a dust collection chamber A and a blower chamber inside the main body 1. B
This is an air permeable partition plate which is fixed to the fan casing 7 and is made of punching metal, wire mesh, etc., which has a large number of through holes so as to have a rectifying effect.

12 is an activated carbon filter sandwiched between the partition plate 11 and the dust collection unit 5.

12 a and 12 b are protrusions provided on the upper and lower surfaces of the main body 1 so as to protrude inward, and for positioning the activated carbon filter 12 .

FIG. 2 is a perspective view showing the configuration of the dust collection unit 5. In the figure, 13 has an opening 14 on the front, both sides are closed by side plates 15, and ventilation is provided between the side plates 15. The frame body is integrally formed with a connecting material 16, and a space 17 is formed inside.

18 is a dielectric filter material attached to the frame 13 so as to cover the outside of the connecting member 16, and 19 is a first breathable ground electrode made of punching metal or the like that is attached tightly to the outside of the dielectric filter material 18. , 20 is a second air permeable ground electrode made of punching metal etc. which is removably attached to the frame 13 so as to cover the opening 14 of the frame 13; This is a discharge section attached to both side plates 15 of the frame body 13 so as to be located in the same position, and is configured as follows.

That is, 22 is a high voltage supply frame attached to both side plates 15 of the frame body 13 via insulators 23, 24 is a plurality of discharge wires stretched between the high voltage supply frames 22, and a first ventilation A dust collecting section is formed between the ground electrode 19 and the dielectric filter medium 18, and a charging section is formed between the second breathable ground electrode 20.

25 is a terminal screw whose one end is connected to the high voltage supply frame 22 via the insulator 23 and whose other end passes through one side plate 15 and comes into contact with a high voltage supply device (not shown).
It becomes the high voltage power supply part of the

An insulator 26 is fixed to one side plate 15 using the terminal screw 25 so as to protrude to the outside, and insulates the terminal screw 25 from the main body 1.

Reference numeral 27 denotes an outwardly protruding portion formed integrally with the other side plate 15 or a protrusion made of an insulator, which engages with the guide portion 8 of the fan casing 7 together with the insulator 26 .

In such a configuration, contaminated air inside the vehicle passes through the main body 1 from the air intake port 4 as shown by the solid line arrow in FIG.
It extends from the opening 14 into the dust collection unit 5.

First, in the vicinity of the opening 14, dust in the air is charged by the discharge wire 24 and the second breathable ground electrode 20 located on the most upstream side, and then the discharge wire 24 and the dielectric filter medium 18 are charged.
In the dust collecting section formed by the breathable ground electrode 19, dust is collected on the dielectric filter medium 18 by Coulomb force.

Furthermore, harmful pollutants, odors, etc. are removed by the activated carbon filter 12, resulting in clean air that is blown out from the air outlet 10 into the vehicle interior.

On the other hand, when replacing the dust collection unit 5 and the activated carbon filter 12, first open the lid 3 and take out the dust collection unit 5 from the opening 2 of the main body 1 upwardly on the front surface.

That is, the protrusion 27 of the dust collection unit 5 and the insulator 26
is slidably guided by the guide portion 8 of the fan casing 9 and taken out, and since the activated carbon filter 12 is released from the grip, the activated carbon filter 12 can be taken out easily.

When inserting the activated carbon filter 12 in the opposite direction, first insert the activated carbon filter 12 along the partition plate 11 with the lower end of the activated carbon filter 12 in contact with the protrusion 12a, and then insert the activated carbon filter 12 with the upper end of the activated carbon filter 12 against the protrusion 12a.
2b for positioning.

Next, the protruding part 27 and the insulator 26 of the dust collecting unit 5 are engaged with the guide part 8, and the dust collecting unit 5 is pushed in until the protruding part 27 and the insulator 26 come into contact with the end part of the guiding part 8, and then the dust collecting unit is removed. If 5 is pushed down slightly, it will be installed horizontally in the installation part 6.

At this time, the activated carbon filter 12 is held and fixed between the end of the dust collection unit 5 and the partition plate 11, and the dust collection unit 5 is fixed by coming into contact with the protrusion 1a of the main body 1 due to the elasticity of the activated carbon filter 12. .

Then, the lid 3 is elastically attached to the opening 2 of the main body 1 to close the opening 2 of the main body 1, and a part of the inner surface of the lid 3 comes into contact with the frame 13 of the dust collection unit 5, and the dust collection unit 5 and the installation part 6 and fix it completely.

In the above embodiment, the dust collection unit is an electrostatic dust collection unit using a dielectric filter medium. The same thing can be done even if it is configured with a targeted dust collection unit.

As described above, in this invention, the inside of the main body is divided into a dust collection chamber and a ventilation chamber by a breathable partition plate, and a dust collection unit is removably housed in the dust collection chamber, so that activated carbon can be removed between the partition plate and the dust collection unit. Since the filter is clamped, the activated carbon filter can be fixed without any special means, and the activated carbon filter can be unfixed by removing the dust collection unit.

Therefore, the effect is that services such as maintenance inspections are extremely simple.
