Description

air sterilizer

The present invention relates to a sterilizer, and more particularly, to an air sterilizer for removing bacteria floating in the air.

As industrialization progresses and urbanization and population density accelerate along with it, the problem of air pollution that humans breathe every day is becoming more serious day by day. Fossil fuels that mankind uses every day inevitably release pollutants harmful to humans into the air, and the concentration of pathogenic microscopic substances such as viruses and bacteria in the air is also increasing. there is. A device used to satisfy these needs is an air purifier or an air sterilizer.

Most of the pollutants in the air are inhaled by humans through breathing and act as the cause of various diseases. As far as it has been revealed, 'hydroxyl radical (OH)' is known to play the most important role in the natural purification process of pollutants. Hydroxyl radical (OH) is a major air cleaning agent that removes various pollutants such as carbon monoxide, sulfur dioxide, and nitrogen dioxide.

In order to generate hydroxyl radicals (OH), ozone and evaporated hydrogen peroxide are currently reacted, or ozone and evaporated limonene solution are reacted. In addition, there is a concern that ozone emitted into the atmosphere without a reaction may adversely affect the human body, and improvement is required.

In addition, the first flow path AP1 and the second flow path AP2 are connected to the mixing space MS, and the evaporated limonene or hydrogen peroxide and ozone are mixed in the mixing space MS to generate hydroxyl radicals.

That is, the first flow path AP1 connects the first air inlet AI1 and the mixing space MS. The second flow path AP2 connects the second air inlet AP2 and the mixing space MS. The third flow path AP3 connects the mixing space MS and the air outlet AO.

In this case, the first flow path AP1 and the second flow path AP2 may be disposed not parallel to each other. For example, the first flow path AP1 and the second flow path AP2 may be disposed perpendicular to each other.

As in the prior art, when the first flow path AP1 and the second flow path AP2 through which the evaporated limonene or hydrogen peroxide flows are formed in parallel directions and mixed with each other, the flow of air forms a laminar flow, so that the evaporated limonene Alternatively, the total amount of hydrogen peroxide and ozone cannot be reacted, and accordingly, unreacted ozone can be discharged, and the amount of hydroxyl radical generated is small compared to the consumption of limonene or hydrogen peroxide.

However, the first flow path AP1 and the second flow path AP2 may be disposed not parallel to each other. For example, when the first flow path AP1 and the second flow path AP2 are disposed perpendicularly to each other, turbulence flow may be induced, thereby improving mixing efficiency.

Meanwhile, the container BO contains liquid and is disposed inside the housing 1100 such that an inlet of the container BO is in contact with the first flow path AP1. As an example, the container BO may be formed to be detachable from the housing 1100 .

In addition, the air sterilization apparatus 2000 further includes a blowing fan driving motor (not shown) for rotating the blowing fan 1200 and a mixing fan driving motor (not shown) for rotating the mixing fan 100.

At this time, the liquid LQ in the container BO, which has passed through the first flow path AP1 and reached the mixing space MS, passes through the second flow path AP2 and the air containing the evaporated liquid LQ. In order to adjust the ratio of the air containing ozone generated by the ozone generator 1300 that reaches the mixing space MS, the air sterilization device 2000, the blowing fan driving motor (not shown) A control unit 1500 that individually controls the rotational speed and the rotational speed of the mixing fan driving motor (not shown) may be further included.

At this time, the container BO stores a limonene solution (olephene), and the controller 1500 controls a blowing fan driving motor (not shown) so that the ratio of ozone:limonene is mixed in the range of 1:0.3 to 3. ) and the rotation speed of the mixing fan driving motor (not shown) can be controlled.

Alternatively, the container BO stores hydrogen peroxide, and the controller 1500 adjusts the rotational speed of the blowing fan driving motor (not shown) so that the ratio of ozone:hydrogen peroxide is mixed in the range of 1:0.3 to 2.

Through this, it is possible to efficiently generate hydroxyl radicals while minimizing the consumption of reactants and suppressing the emission of ozone.

On the other hand, during manufacturing, the rotational speeds of the blowing fan 1200 and the mixing fan 1400 may be set, and during driving, the amount of evaporated limonene or hydrogen peroxide and the amount of ozone are sensed, respectively, so that the control unit 1500 Through this, the rotation speed of the blowing fan 1200 and the mixing fan 1400 may be controlled.

Referring to FIG. 4 , since the first flow path and the second flow path are arranged vertically, generation of turbulence can be confirmed, and limonene and ozone can be mixed more efficiently through such turbulence.
