Abstract

PROBLEM TO BE SOLVED: To provide a power source of good dust collecting efficiency by connecting a plus voltage, a minus voltage and a common ground to a plus electrode, a minus ion electrode and a shield part at the rear of a device respectively. SOLUTION: A plus high voltage 2 and a minus high voltage 4 are simultaneously generated in a secondary part to an oscillation part, and a ground 3 is shared by them. In this case, since the ground 3 for both plus and minus high voltages 2, 4 is common to them mechanically, the trouble that the dust collecting efficiency lowers is not produced. The common ground 3 is connected to a shield part 8 at the rear of a device, allowing suck a weak point in an ionic air purifier that the rear of the device is soiled to be corrected.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high voltage power supply used in an air cleaning device.

[0002]

2. Description of the Related Art Conventionally, a power supply used for an air cleaning device has a problem in cost, and since it uses a power supply that generates positive high voltage and negative high voltage at the same time, it is not necessary to be aware of it. Since it is used in common, it does not cause trouble, but in the case of power sources where both positive and negative high voltages are independent, if the ground is not used in common, the dust collection efficiency will be extremely poor. .

[0003]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide a power source with high dust collection efficiency even when both positive and negative high voltages are independent power sources. There is a solution to the fact that the back of the device becomes very dirty.

[0004]

As means for solving this problem, in the ion type air purifying apparatus, the ground is commonly connected to both positive and high pressure, and the ion ground air purifying apparatus is connected to the shield portion on the rear surface of the apparatus. Is.

[0005]

The object of the present invention is to provide a power source for operating the ion type air cleaning device with high dust collecting efficiency, and to solve the drawback of the power source, that is, the back surface of the device.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1 of the present invention, in this case, the most frequently used power source generates positive high voltage 2 and negative high voltage 4 at the same time in the secondary section from the oscillating section 1. , The earth 3 is common.
In this case, since both the brass 2 and the minus 4 high-voltage ground 3 are commonly used, the trouble of deteriorating the dust collection efficiency does not occur. The common ground 3 is connected to the shield portion 8 on the rear surface of the apparatus for the purpose of solving the drawback of the ion type air purifying apparatus that the rear surface of the apparatus is contaminated.

In the case of FIG. 2, the positive high voltage 10 and the negative high voltage 11 are independent power sources. In this case, if it is forgotten to make the ground 3 common, the dust collection efficiency is poor and it does not become a product. In such a case, it is solved by connecting the plus 3 and minus 4 grounds 3 in common. By connecting this common ground 3 to the shield section 8 on the rear surface of the apparatus, the contamination on the rear surface of the apparatus, which is a drawback of the ion type, can be solved.

[0008]

The effect of the present invention is to provide a power source with a high dust collection efficiency and solve the problem of the ion type, that is, the dirt on the back surface of the apparatus.
