Description

Composite Humidifier {HYBRID HUMIDIFIER}

The present invention relates to a combined humidifier. More specifically, by injecting air bubbles into a water tank containing warm humidification water, and by spreading the injected air bubbles in a state containing warm moisture, it relates to a complex humidifier capable of providing adequate humidity to the interior space.

In general, a humidifier refers to an electronic product that generates water vapor to maintain indoor air at an appropriate humidity (55 to 60%). These humidifiers can be largely divided into ultrasonic type, heating type, and vaporization type humidifier according to a method of maintaining indoor humidity.

Ultrasonic humidifiers are humidifiers that generate micro water molecules by generating ultrasonic vibrations in a water tank, and have the advantage of low noise and low cost. However, since ultrasonic humidifiers spray water molecules rather than water vapor, water droplets may form around the humidifier, and foreign substances present in the water tank may be sprayed together. do.

The heated humidifier is a humidifier that heats water to 100° C. and sprays vapor to evaporate, and has a wide humidification range and is safe because foreign substances are not bound to the water vapor. However, if you touch the steam heated to 100° C., there is a risk of burns, and it is not economical because it consumes a lot of power compared to other humidifiers. In addition, the humidification effect cannot be provided until the water boils to 100°C, so if you put cold water in the water tank, you have to wait up to 20 minutes or more.

A vaporization humidifier is a humidifier that injects wind into a humidifying filter (fiber filter, disk filter) wet with water and sprays water vapor that evaporates naturally. However, there are disadvantages in unsanitary conditions as the noise of the fan operating to generate the natural vaporization phenomenon is large, cleaning is cumbersome depending on the type of humidification filter, and mold may form on the filter itself containing water.

Combination of ultrasonic and heating type humidifier is a humidifier that sterilizes water through heat and sprays it, and has the advantage of removing foreign substances. There are disadvantages.

Accordingly, the present invention combines a heating type and a vaporization type humidifier, using a humidifier of a new configuration that does not exist in the existing, excellent humidification effect, and proposes a composite type humidifier that is convenient to use and maintain because there is no filter.

An appropriate amount of water level required to provide a humidifying effect based on the volume of the water tank 100 may be displayed on the outer surface of the water tank 100 . The composite humidifier 1000 of the present invention generates steam (warm air) at 40°C to 85°C without boiling the water for humidification in the water tank 100 to 100°C in the general operation mode, so that a humidifying effect can be achieved in any one space. In order to provide this, it is possible to provide safer steam than the conventional heating-type humidifier, and to generate relatively less noise than the conventional vaporization type, thereby solving the inconvenience of use.

The air injection unit 200 may inject air bubbles into the humidification water. Here, the air bubble may mean an air bubble having a size of 1 nm to several mm.

Here, the diameter d2 of the plurality of separated nozzles is smaller than the initial diameter d2 to which the air is supplied, so that the air introduced through the air pump 210 may be pulverized.

It will be described with reference to FIG. 1 again.

Air bubbles discharged from the air injection unit 220 may have buoyancy and rise from the bottom surface of the water tank 100 to the surface of the humidification water, and the air bubbles sprayed or diffused into the air may hold humidity. That is, in the present invention, by dividing the air injected into the humidification water as small as possible, the surface area where the air and water meet is maximized, and the humidification effect can be maximized.

In addition, in order to maximize the humidification effect using air bubbles, it may be preferable that the temperature of the water for humidification is at least a certain temperature. Accordingly, the present invention may be provided with a heating unit 300 so that the air bubble to hold warm moisture.

The heating unit 300 may transfer thermal energy to water for humidification.
