Description
[0001] The present invention relates to an air purifier which purifies the air in an indoor environment in a building by maintaining the humidity balance in the environment.
[0002] Today, the need for ventilation and the need for fresh air becomes more important in environments such as homes and offices especially in high-rise buildings. Plants can be a temporary solution for daytime but when the sunlight disappears, plants also start to produce carbon dioxide like human beings and the air quality of the environment decreases. Especially in high-rise buildings, it is not always possible to continuously keep the windows open and ventilate the environment. The continuously rising carbon dioxide density in the air adversely affects human health. The amount of oxygen in the environment directly affects the metabolic rate of people and the lack thereof creates weakness and fatigue in humans. Ensuring that the amount of oxygen in the interior environment does not fall below a certain level while reducing the amount of carbon dioxide generated in the environment makes the human metabolism much more vivid and vigorous.
[0003] Today, devices wherein the air is purified by means of processes such as electrodialysis and the oxygen density in the environment is increased by means of humidity. However, in such devices, as the oxygen density in the air increases during the processes performed to increase the oxygen density, hydrogen gas which is harmful for humans is also released. The hydrogen gas can cause deflagration when the density in the air by volume reaches 4% and explosions as the density reaches 7%. Furthermore, the devices wherein the humidity in the environment is used to increase the oxygen level cause the air in the interior environment to be dryer than normal and thus, decrease the air quality.
[0004] Turkish patent application no. TR201921330A discloses an air purifier comprising a body, an air inlet opening, a fan for directing the air through the air inlet opening into the body; and an air outlet opening for releasing the purified air out of the body.
[0005] Chinese patent no. CN105617842B discloses a device for separation and purification of carbon dioxide, comprising a water electrolysis system, a carbon dioxide absorption device, and a gas-liquid collection system.
[0006] European patent application no. EP3524337A1 discloses an electrolyzer and electrolytical process for recovery of CO2 from air and hydrogen generation. International patent application no.

[0007] United States patent application no. US2012067304A1 discloses a method for reducing engine system fuel requirement wherein engine waste energy is recovered and converted into usable energy.
[0008] The aim of the present invention is the realization of an air purifier which balances the humidity in the environment and also, the waste hydrogen gas is removed.
[0009] The present invention is an air purifier according to claim 1.
[0010] The air purifier of the present invention comprises an air inlet opening through which the air is sucked in, a CO 2 absorbing unit wherein the carbon dioxide is absorbed from the air having high carbon dioxide density, and an air outlet opening through which the air which is cleansed of CO 2 is sent back to the environment wherein the air purification is performed.

[0015] The air purifier of the present invention comprises a combustion chamber. The hydrogen gas which is released as a result of the processes performed in the air purifier is burned and converted to hot water vapor.
