Description

A humidifier with air cleaning function < RTI ID = 0.0 >

The present invention relates to a humidifier including an air purifying function, and more particularly, to a humidifier having an excellent air purifying function.

In general, indoor air can maintain respiratory disorder and disease by maintaining proper humidity (about 60%), and maintain a pleasant indoor atmosphere. There is no proper vapor element in the room, and it is easy to get dry if the temperature rises. At this time, the humidifier can control the humidity in the air, which is made by granulating the clean water by electricity and spraying it into the room.

These types of humidifiers include a centrifugal atomizing humidifier (centrifugal atomization type: a method in which water is centrifugally blown and granulated), an ultrasonic humidifier (in an electric circuit, an electric signal of a certain frequency is generated and transmitted to a vibrator placed in water Generating ultrasonic waves generates cavitation (a vacuum phenomenon that occurs after a propeller), an electrothermal humidifier (a method of generating steam by heating water with a heater or an electrode), a filter And a vapor-type humidifier (a method in which water is evaporated by passing air through a wet filter).

The air cleaner purifies the air. The air cleaner sucks the contaminated air into the fan, and collects fine dust or bacterium up to about 0.01 μm by the filter, thereby taking out the body odor and odor.

In this case, there are three types of filters: a mechanical filter for collecting dust using malt-peen or glass fiber; a high-performance filter for collecting particulates using glass fiber and cellulose fiber; and a deodorizing filter using activated carbon.

In addition, an electric dust collecting apparatus for adding dust to the filters and charging the dust by high-pressure discharge and collecting dust may be used together.

In recent years, a multi-function humidifier having the above-described humidifying function and air purifying function has been developed in order to meet consumer demands.

However, in the world, the number of consumers who want to purchase a multifunctional humidifier that combines humidification function and air purifying function due to ultrafine dust or dirt, has increased greatly. However, most of the multifunction humidifiers, which combine humidification function and air purifying function, The function is greatly reduced.

The first ultrasonic oscillation unit 210 includes a first ultrasonic oscillator 211 and a gas supply member 230 coupled to the first ultrasonic oscillator 211. The second ultrasonic oscillation unit 220, The second ultrasonic oscillator 221 is in contact with water supplied from the water reservoir 110 to vaporize water in contact with the second ultrasonic oscillator 221, .
