Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an improvement to an automobile air purifier that removes fine particles contained in the air inside a car, particularly cigarette smoke and odors, to purify the air inside the car.

[Prior art]

FIG. 1 is a diagram showing a conventional automobile air cleaner (air cleaner) disclosed in, for example, Japanese Utility Model Application Publication No. 55-16837. In the figure, 1 is the ceiling of the car, 2 is attached to the ceiling 1 of the car by screws, and has a plurality of air intake holes 2a on the front side.
3 is a motor disposed inside the main body 2; 4 is a fan attached to the rotating shaft of the motor 3; 5 is a holding frame attached to the main body 2; A plurality of vent holes 5a are formed. Reference numeral 6 denotes a filter medium held outside the holding frame 5, which is made of a dielectric material and has a U-shaped cross section. Reference numeral 7 denotes an air suction section in which a plurality of air suction ports 7a are formed, and is constituted by a ground electrode, and is held by the holding frame 5 on the open end side of the filter medium 6. Reference numeral 8 denotes a discharge wire stretched across the inner space of the filter medium 6, which charges fine particles such as cigarette smoke sucked into the inner space of the filter medium 6. Reference numeral 9 denotes a breathable ground electrode having a plurality of vent holes 9a, and is arranged around the outer periphery of the filter medium 6 by the holding frame 5. 5 to 9 constitute a dust collection unit 10. Reference numeral 11 is an activated carbon filter that removes harmful gases, odors, etc. from the air. 12 is an air outlet provided at the rear of the main body 2.

Next, the operation will be explained. When the motor 3 is energized and rotates, the fan 4 rotates, and the dirty air inside the vehicle is drawn from the direction of arrow A in the figure to the air intake port 2a.
It flows into the main body 2 through. The air that has flowed into the main body 2 passes through the air suction port 7a of the air suction section 7 and is sucked into the internal space of the filter medium 6. Then, a high voltage is applied between the discharge wire 8 and the ground electrode of the air suction section 7 and the breathable ground electrode 9 by a high voltage supply device (not shown), and the air sucked into the internal space of the filter medium 6 is heated. The fine particles contained therein, such as cigarette smoke and other dust, become electrically charged. These charged particles are drawn to the breathable ground electrode 9 through the ventilation hole 5a by the coulomb, but at this time, they are collected by the filter medium 6. The air from which particulates have been removed is discharged to the outside of the dust collection unit 10 through the vent 9a of the breathable ground electrode 9, and further passes through the activated carbon filter 11. When the air passes through the activated carbon filter 11, harmful gases, odors, etc. in the air are removed. The clean air thus obtained flows in the direction of arrow C in the figure, and is further blown out into the vehicle from the air outlet 12 in the direction of arrow B by the fan 4.

Although the conventional air cleaner is as described above, the air intake port 2a and the air suction port 7a are not provided at the front of the main body 2 and the air suction portion 7, respectively. As a result, the amount of dirty air taken into the vehicle is small, and the flow rate of the air taken in is high, so that the particulates contained in the air are not sufficiently charged. Therefore, it has the disadvantage that the amount of air that can be cleaned within a unit time is small.

[Summary of the idea]

This idea was made in order to eliminate the above-mentioned drawbacks of conventional air purifiers for automobiles.The air suction part was made to protrude from the open end of the filter medium, and this protruding part Of the main body that has a plurality of air suction ports formed on the front surface, upper and lower surfaces, or side surfaces, and houses the air suction section, at least the front surface, the upper and lower surfaces, or the side surfaces of the air suction section in which the air suction ports are formed. It is an object of the present invention to provide an air cleaner for an automobile that has high efficiency in sucking in dirty air and high cleaning efficiency by forming a plurality of air intake ports on two opposing surfaces.

[Example of idea]

An embodiment of this invention will be described below with reference to FIG. In the figure, 2 is a main body having a plurality of air intake ports 2a on the front and lower surfaces, and 7 is an air suction part constituted by a ground electrode, which protrudes outside from the open end of the filter medium 6, and this protruding part. A plurality of air suction ports 7a are formed on the front surface and the upper and lower surfaces. The front and lower surfaces of the main body 2, on which the plurality of air intake ports 2a are formed, are opposed to the front and lower surfaces of the air suction section 7, respectively. Further, the protruding portion of the air suction portion 7 has a U-shaped cross section.

Note that the other configurations and operations are the same as those of the conventional air cleaner for automobiles shown in FIG. 1, and a description thereof will be omitted.

With the above configuration, the air suction amount of the writing style 2 and the air suction part 7 increases, and the filter medium 6
Since air flows into the internal space through the air suction ports 7a formed not only on the front surface of the air suction section 7 but also on the upper and lower surfaces, the inflow speed of dirty air is reduced. Therefore, the amount of air that can be inhaled within a unit time increases, and fine particles such as cigarette smoke and other dust contained in this inhaled air can be efficiently charged. Since the amount of air that can be purified increases, the efficiency of the air purifier will improve.

Although the above embodiments have been described with respect to the case in which the air suction ports 7a are provided on the front and upper and lower surfaces of the air suction portion 7, even if the air suction ports 7a are provided on the front and both sides,
Further, the air suction port 7a may be provided on the entire front surface, upper and lower surfaces, and both side surfaces. Further, the shape of the air suction portion 7 is not limited to a rectangular shape, but may be formed in a protruding spherical shape. Also, the air intake port 2a provided in the main body 2
Since it is better to face the air suction port 7a provided in the air suction portion 7 on as many surfaces as possible, it is not limited to the two surfaces of the front and bottom surfaces, but may be provided on the side surfaces.

[Effect of idea]

As described above, in this invention, the air suction part is made to protrude outside from the open end of the filter medium, and a plurality of air suction ports are formed on the front surface, upper and lower surfaces, or side surfaces of this protruding part, and the air suction part is Since a plurality of air intake ports are formed on a surface of the main body housing the suction section that faces at least two of the front surface, top and bottom surfaces, or side surfaces of the air suction section where the air suction port is formed, dirty air is removed. It is possible to provide an air purifier for automobiles with high suction efficiency and high cleaning efficiency.
