JPH08191784A - Cleaner having fine particle collecting function - Google Patents

Abstract

PURPOSE: To collect a fine particle dust such as toner by providing a hyperfine mesh type paper pack filter, a dust collecting filter and exhaust filter using electrostatic filters consisting of polymer dielectrics, and a motor adapting a shield type bearing in a bearing part. CONSTITUTION: This cleaner has a hyperfine mesh type paper pack filter 1, a dust collecting filter 2 and exhaust filter 3 using electrostatic filters consisting of polymer dielectrics, and a motor 5 adapting a shield type bearing 4 in a bearing part. The motor 5 is partially housed in a noise eliminating cylinder 6. A suction hose is mounted on a hose mounting hole 7. The hyperfine mesh constituting the paper pack filter 1 has a diameter of 0.7μ. The cleaner having this constitution can collect a material having a particle size up to 0.3μ. It is also resistant to the melting of the suction hose by carbon toner or the bearing breakage by toner magnetic body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaner for improving the environment of a workplace where toner is used such as a printer and a copying machine and a workplace (such as a food maker) where it is necessary to keep the room clean.

[0002]

2. Description of the Related Art Conventionally, the size of particles to be collected by a cleaner is 1 μm.
Dust with a diameter smaller than that was discharged into the air and scattered. Further, the bearing of the motor uses an open type bearing, and dust protection against fine dust has not been considered.

[0003]

The carbon toner used in printers and copiers has an ultrafine particle size of about 0.3 μm. Therefore, when it is sucked by a conventional cleaner, the toner cannot be collected and cannot be collected. It was diffused into the air from the exhaust port.
In addition, the magnetic substance contained in the toner has entered the bearing portion of the motor, impairing the bearing function of the motor and causing dielectric breakdown of the coil. Further, the bellows suction hose made of vinyl chloride resin is melted by the carbon toner and becomes unusable, resulting in a shortened service life.

[0004]

A cleaner having a function of collecting fine particles according to the present invention is a dust collecting filter and an exhaust gas using an ultrafine mesh type paper pack filter and an electrostatic filter made of a polymer dielectric, respectively. It is equipped with a filter and a motor that uses a shield type bearing in its bearing.

[0005]

FIG. 1 shows an embodiment of the present invention.
This cleaner includes an ultrafine mesh type paper pack filter 1, a dust collecting filter 2 and an exhaust filter 3 each using an electrostatic filter made of a polymer dielectric,
A motor 5 having a shield type bearing 4 is provided in the bearing portion. A part of the motor 5 is housed in the silencer cylinder 6. This cleaner has a suction hose (not shown) made of polypropylene resin. The suction hose is attached to the hose attachment port 7. Paper pack filter 1
The diameter of the ultrafine mesh forming the is 0.7 μ.

The cleaner having this structure can collect substances having a particle size of up to 0.3 μm. In addition, it is resistant to the dissolution of the suction hose with carbon toner and the bearing damage due to the magnetic toner.

[0007]

As described above, according to the present invention, the ability to collect fine particles can be remarkably improved, and therefore it is most suitable for collecting dust having a fine particle size such as toner.

Further, in order to keep the environment of the place of use cleaner than ever, it is very effective in improving the working environment even for manufacturers handling OA equipment such as printers, semiconductors, liquid crystals, foods and the like.

Further, since the bearing of the motor is a shield type bearing, it is also resistant to magnetic substances such as toner, and the suction hose is also made of a different material so as to be resistant to melting by the toner. The life can be greatly extended.
