Description

Electronic Air Purifier with Pleated Dust Collector

The present invention relates to a dust collector plate of an electronic air purifier, and in detail, the surface area of the dust collector plate is increased by making the structure of the dust collector plate corrugated, and the efficiency of corona discharge is increased at the peak portion of the corrugation, thereby increasing the dust collecting efficiency of the dust collector. An electronic air purifier having a dust collecting plate of a structure

In general, air purifiers are used to remove various bacteria and viruses such as bacteria and viruses that float indoors and cause respiratory diseases in humans.

There are two types of air cleaners: corona discharge and fan and filter methods. Corona discharge uses a smaller dust collection rate than fans and filters that filter out dust that is too small. Ozone generated during high and corona discharge removes bacteria and viruses and deodorizes.

Here, the method using the corona discharge is a form of gas discharge when the electric field is not equal between the conductors, a large amount of charge is generated on the negative voltage side during the corona discharge.

The generated charge causes ionization to surrounding molecules, which in turn charge the surrounding molecules with negative ions.

Negatively charged molecules are attracted to each other by the positive voltage side and the coulomb force, which causes the negatively charged molecules to move toward the positive voltage line.

Electronic air purifier using corona discharge is a method of generating a spinning needle to generate a large amount of electrons, and dust collected by negative ion charged dust by the coulomb force in the dust collecting plate with a positive voltage.

6 is a view illustrating a conventional electronic air purifier dust collecting plate and the structure and operation state of the electronic air purifier are described as follows.

The electronic air purifier has a cylinder 102 formed by rolling a thin plate of non-conductor over a body incorporating a high pressure circuit and the like in the center, and a cylinder along the outer peripheral surface of the cylinder 102 at the upper end of the body around the lower end of the cylinder 102. A plurality of sharp spinning needles that emit electrons around the cylinder 102 at regular intervals from the 102 are provided.

The radiating needle is applied with a negative voltage of high pressure and a corona discharge occurs between the dust collector 103 of a flat type that is applied with a positive voltage of high voltage fixed at regular intervals along the outer circumferential surface of the cylinder 102.

The dust particles charged by the corona discharge are collected by moving toward the dust collecting plate 103. The dust collecting plate 103 is provided with a clip 105 for fixing the dust collecting place 104, and the dust collecting stationary fixed by the clip 105. 104 uses kitchen towels, toilet paper, and the like that can be easily obtained from the surroundings.

However, in the flat dust collector 103 having such a configuration, the positive charge is concentrated on the upper and lower ends of the dust collecting plate 103 by the phenomenon that the charge is concentrated on the tip, especially the pointed portion, and concentrated on the upper and lower ends of the dust collecting plate 103. Since the positive charge attracts the dust charged to the negative charge, the dust is concentrated on the upper and lower ends of the dust collecting plate 103 of the dust collecting plate 104 fixed to the clip 105 and covered on the outer peripheral surface of the cylinder 102 and the dust collecting plate 103. do.

Therefore, since the dust is not evenly collected in the conventional dust collecting plate 103, and is concentrated only at both ends of the dust collecting plate 103, there is a demand to increase the dust collecting efficiency by using this property.

The present invention has been devised to improve the conventional problems as described above and increase the efficiency of the dust collector, by making the structure of the dust collector plate pleated to prevent dust from being concentrated by collecting dust at both ends of the dust collector plate, increase the surface area of the dust collector plate The purpose of the present invention is to provide an electronic air purifier having a dust collecting plate having a corrugated structure in which the efficiency of corona discharge is increased at the peak portion of the corrugation to increase dust collecting efficiency of the dust collector.

The present invention for achieving the above object is a strong negative voltage is applied to the radiation needle and the electron generated by the corona discharge and the radiation needle to generate a large amount of negative charge generated by the corona discharge toward the dust collector is subjected to a positive voltage A clip for fixing a dust collecting plate to absorb dust collected by being surrounded by a pleated dust collecting plate collecting dust with dust, a cylinder for holding the dust collecting plate and the dust collecting plate and fixing the collecting plate, and an outer circumferential surface where the collecting plate is installed. The present invention provides an electronic air purifier composed of a cover covered by a cylinder part of the main body to secure the safety of the user from the main body in which the corona discharge occurs.

Radiating needle generating a large amount of negative charge generated by corona discharge toward the dust collector plate 3 subjected to a strong negative voltage at a small distance from the cylinder 2 around the lower part of the cylinder 2 on the body ( 7) is located round.

The dust collecting plate 3 is wound around the outer circumferential surface of the cylinder 3 at regular intervals, and collects the negatively charged dust that is charged to the electrons generated by the spin needle 7 by corona discharge. Pleated in (3).

Here, the outer circumferential surface of the cylinder 2 on which the dust collecting plate 3 is installed surrounds the dust collecting paper, and the dust collecting paper is fixed by a clip 5 installed at one side of the dust collecting plate 3 and replaced when the dust collecting paper becomes dirty.

In addition, in the electronic air cleaner using corona discharge, a voltage of more than several thousand volts is normally applied between the spin needle 7 and the dust collecting plate 3 to generate corona discharge. ) To the cylinder (2) and then fixed to the body (9).

Referring to the working state of the subject innovation constituted as follows.

In the high-pressure circuit in the electronic air cleaner body, a negative voltage of thousands of volts is applied to the radiating needle 7 and a positive voltage of several thousand volts is applied to the dust collecting plate 3, so that a corona discharge occurs between the radiating needle 7 and the dust collecting plate 3. .

When the corona discharge occurs, a large amount of electrons are generated from the spin needle 7 toward the dust collecting plate 3, which causes ionization to molecules around the spin needle 7, thereby supplying negative ions to the spin needle 7. .

The negative ions make negative charge to dust floating around in the air by turning the oxygen into negative ions one by one.The coulomb force acts between the negative ions and the charged dust and the dust collector 3 under high voltage. The attractive force acts, and the negatively charged dust moves to the dust collecting plate 3 on which the electric field lines are formed.

The moved dust is collected in the dust collector plate 3 fixed to the cylinder 2 at regular intervals and the dust collector surrounding the outer circumferential surface of the cylinder 2.

In the present invention, in order to increase the efficiency of the dust collecting plate 3 in the air cleaning process of the electronic air cleaner, as shown in FIGS. 2 and 3, horizontal wrinkles are formed in the thin metal dust collecting plate 3.

The wrinkles thus formed increase the surface area of the dust collecting plate 3, and dust is evenly concentrated in each of the plurality of corrugated mountains 8, thereby increasing the dust collecting efficiency of the dust collecting plate 3.

By sharpening the corrugated acid 8, the efficiency of the dust collecting plate 3 can be further increased, which is based on the principle of magnetic concentration at the end of the magnet and lightning strikes on the lightning rod with the tip of the building. The principle is to focus on sharp parts.

4 and 5 in the present invention is a representation of the vertical pleated dust collecting plate 4 in which the pleats are formed vertically in another embodiment of the pleated dust collecting plate 3.

The working process of drilling a screw hole in the dust collecting plate 3 or installing a clip 5 for fixing the dust collecting plate 3 to fix the cylinder 2 and the dust collecting plate 3 with a screw is more convenient than the horizontal corrugated dust collecting plate 3. In order to form the vertical wrinkles in the dust collecting plate (4).

Thus, the installation of the clip 5 while increasing the surface area and the dust collection efficiency of the dust collecting plate 3 by using the dust collecting plate 4 of the vertical corrugation structure which does not corrugate only the installation part of the clip 5 and the screw hole part of the dust collecting plate 4 in this way. And screw drilling can be facilitated.

As described above, the present invention increases the surface area of the dust collecting plate by increasing the structure of the dust collecting plate and increases the efficiency of corona discharge at the peak of the corrugation, thereby increasing the dust collecting efficiency of the dust collector and dusting on the dust collecting part on the upper part of the dust collecting plate. It can reduce dust collection.
