Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a small air purifier installed in a car or the like.

2. Description of the Related Art Conventionally, this type of air purifier has a fan 1 for sucking air and a charged filter 2 for filtering the air, as shown in FIG. By applying electric charges to the dust, the charged filter 2 was able to attract the dust.

Problems to be Solved by the Invention As shown in the above configuration, in order to attract dust, give it an electric charge, and make it adhere to the filter, a fan 1 and a filter 2 are required.
In addition, a discharge device 3 is required, and the main body becomes large to accommodate them.

As a result, the mounting locations are limited due to space limitations, and the mounting work is also difficult.

Furthermore, in order to reliably charge the dust passing between the discharge devices 3, the discharge must reach the entire area, and a large number of discharge needles 4 are required as shown in FIG. Therefore, processing was also difficult.

In addition, the discharge needle was stained with grime and the like, reducing discharge performance and shortening the lifespan of dust collection.

The present invention solves these problems by providing an air purifier that has a simple structure, a small overall size, a small installation space, and can be easily installed in a car, etc., and yet has good dust collection performance.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention makes the blades of the fan conductive, and attaches discharge needles to the blades. conduction with
The fan itself has a discharge function by discharging it to a grounding body such as a lath net placed in front of the fan.

Function: With the above configuration, the fan itself has the function of sucking air;
Since it also functions as a discharge device that charges the dust in the suction air, the structure of the main body can be made smaller, and therefore the installation space is small and installation is easy, increasing the number of car models that can be installed.

Furthermore, since the fan rotates at high speed, even if the number of discharge needles attached to the blades is small, the discharge can be applied to the entire air passage, so the number of machining steps can be reduced.

In addition, even if the discharge needle gets dirty, it is blown away by centrifugal force, keeping it clean and maintaining excellent discharge performance.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIGS. 1 to 4, reference numeral 11 denotes an air purifier main body, which incorporates a fan 12 and a motor 13 for driving it.

The fan 12 consists of conductive blades 16 held between a conductive disk 14 and an insulating disk 16, and a rotating shaft 17 that supports the conductive disk 14 and the insulating disk 16. By attaching 16 to the motor shaft 18, it is linked to the motor 13.

A high voltage power source 19 is arranged on the conductive disk 14 side of the fan 12, and a rotating shaft 17 is rotatably connected to an output terminal 20 wired from the high voltage power source 19. 1
7 - conductive disk 14 - vane 16 and high voltage is applied.

A discharge needle 21 is attached to the blade 16 and faces the reed so as to discharge a discharge to a lath mesh metal plate 23 disposed inside the intake port 22. Note that the metal plate 23 is grounded.

24 is a charged filter that is detachably installed inside the exhaust port 25.

In the above configuration, the air sucked by the fan 12 enters the main body 11 through the intake port 22, and the lath mesh metal plate 2
Transmits 3. At that time, the blade 16 to which the discharge needle 21 is attached
Since high voltage is applied through the rotating shaft 17 and the conductive disk 14, discharge is generated from the discharge needle 21 toward the metal plate 23.

Since the fan 12 rotates at a high speed, even a small number of discharge needles will cause a continuous discharge, so that the discharge will not occur in the entire air passage, and all the dust in the suction air that passes through the metal plate 23 will be discharged. Gives a charge.

Furthermore, when the suction air containing electrically charged dust passes through the charged filter 24, all of the dust is removed from the filter 24.
4 and becomes clean air and is discharged from the intake port 26.

Even with such a small number of discharge needles, the same effect as when a larger number of discharge needles are provided during the rotation of the fan 12 is achieved, and excellent dust collection performance is achieved.
Since the above-mentioned discharge action is achieved with the above, no space is required, and together with the convex, a space-saving air purifier can be provided.

Furthermore, even if the tip of the discharge needle 21 is contaminated with grime, it is blown away by the centrifugal force and remains clean, providing excellent discharge performance, ie, dust collection performance.

Effects of the Invention As described above, according to the present invention, since the fan that sucks air and the discharge device are integrated, the overall configuration can be made compact, and installation is easy, and it does not take up much space. It can be easily installed in cars, etc.

Furthermore, since the fan to which the discharge needles are attached rotates at high speed, discharge can be made continuously even with a small number of discharge needles, and all the air passages can be covered. Therefore, the number of processing steps for attaching the needle can be reduced. Furthermore, although the tip of the discharge needle gets dirty due to the buildup of gunk, it is blown away by centrifugal force, so it is always kept clean, maintains excellent discharge performance, and does not require maintenance such as cleaning, and exhibits high performance. be.
