Apparatus and method for controlling air cleaning

Abstract

The invention discloses a device and method for controlling air purification. The equipment includes an air cleaning element, a current detector, an AC high voltage generator and a control unit. The air purification element generates negative ions and ozone using plasma discharge and purifies indoor air by the negative ions and ozone. The current detector detects the state of the current flowing through the air cleaning element. The AC high voltage generator generates AC high voltage and applies the AC high voltage to the air cleaning element. The control unit changes the magnitude of the AC voltage applied to the air cleaning element by the AC high voltage generator based on the current detection signal received from the current detector. Therefore, based on the state of the indoor air, ozone below the limit value is sufficiently generated, thereby increasing the air cleaning effect to more effectively sterilize and purify pollutants.

Description

technical field [0001] The present invention relates to an air purification device provided in an air conditioner, an air cleaner, etc., and more particularly to a device and a method for controlling air purification, which can be adequately controlled by detecting the current flowing through an air purification element and according to the detected current The amount of ozone produced to purify the indoor air. Background technique [0002] The air purification apparatus generates many negative ions using an air purification element, which refers to a recently developed surface discharge type negative ion generator, and thereby purifies indoor air using the generated negative ions. [0003] figure 1 is a block diagram showing the structure of an existing air purification control device, and figure 2 It is a figure which shows the operation control state of this conventional air purification control apparatus. refer to figure 1 and 2 , an existing air purification contr...

AI Technical Summary

Problems solved by technology

Therefore, since the air cleaning element 7 cannot be operated corresponding to the pollution degree of the indoor air, the indoor air cannot be effectively purified.

[0009] In particular, the above-mentioned existing air purification control apparatus has a DC high voltage generator 5, but it is impossible to easily control the characteristics of the DC high voltage generator 5

For this reason, although using the DC high voltage generator 5, it is also difficult to easily generate ozone below a predetermined limit value with the air cleaning element 7

Therefore, although ozone has a high sterilizing effect, it is difficult to sterilize and purify indoor air because ozone below a predetermined limit value cannot be easily generated.
