Description

IoT Smart Air Purification System with Ease of Detachment and Clean Outdoor Induction Structure of Sterilization Unit Frames}

The present invention relates to an air purification apparatus and a control method thereof, and more particularly, a sterilization unit having a clean, ventilation complex purification structure that sterilizes and purifies contaminated indoor air as well as external contaminated air to supply clean air to the room. It relates to an IoT smart air purification device having a structure that allows easy attachment and detachment of the frame and a clean air-induction structure.

As a method of purifying the air, a filtration dust collection method that collects and removes pollutants using a HEPA filter, an adsorption method using a filter such as activated carbon, a purification method using plants, a purification method by air circulation, and a photocatalyst are used. There are methods to use.

Among them, the purification method using the HEPA filter has a great advantage in removing fine dust, and the method using a photocatalyst has high decomposition rate of volatile organic compounds and has sterilization and antibacterial functions, so it is possible to remove airborne bacteria and viruses as well as HEPA filter. Unlike the other, it has the advantage of being able to use it for a long time.

In order to activate such a photocatalyst, a UV light source is required, but conventionally, a UV fluorescent lamp has been mainly used. UV fluorescent lamps have a larger external size and shorter life than LED lamps, and it was difficult to assemble products and maintain airtightness of filter modules due to wiring interference such as ballasts, and they have low energy efficiency and contain mercury, which adversely affects the environment. It has shortcomings, and efforts have been made to solve it.

Recently, as UV LEDs have been developed in a variety of ways and the price is getting cheaper, the demand for sterilization logs is increasing a lot, and UV LEDs have a longer life than general UV fluorescent lamps, can be powered on/off instantly, and have high energy efficiency. , Environmentally friendly.

When manufacturing an air purifying device using a conventional UV fluorescent lamp, it is difficult to configure various sterilization units due to the structural characteristics of the UV sterilization lamp, and the problem of increasing electricity consumption due to air resistance due to the sterilization lamp and the sterilization lamp when replacing the filter It is difficult to replace due to spatial interference such as electrical wiring of the lamp and the risk of damage to the lamp, which requires management by an expert.

However, when manufacturing an air purifier using UV LEDs, unlike conventional UV fluorescent lamps, UV A, UV B, and UV C that generate only a specific wavelength range can be combined and arranged. It has become easier to implement the wavelength.

Meanwhile, various types of air purification devices for purifying and supplying contaminated air have been put into practice in consideration of a situation in which air pollution harmful to the human body gradually increases due to negative changes in the living environment.

In general, such an air purifying apparatus employs an antibacterial filter member for removing bacteria contained in the air in addition to a dust collection method by collecting microscopic impurities (e.g., dust, etc.) as pollutants contained in indoor air. You will have a structure.

In addition, recently, various types of filter structures for providing purified air including components that are natural and beneficial to the human body (eg, supply of mineral components, radiation of far infrared rays, etc.) are attracting attention.

Such a dust collection method using a filter can increase the purification efficiency of fine dust, but the possibility of causing secondary pollution may increase due to desorption and scattering of pollutants collected on the filter surface. There is a limit in which high purification performance cannot be expected because VOC can rather increase.

In addition, when ventilation is performed by opening the window, if the air quality is poor, there is a problem that the concentration of fine dust in the room rapidly increases due to the reverse inflow of fine dust. In the case of a mechanical ventilation system by total heat exchange, CO₂ and VOC Although reduction is possible, many practical problems such as increase in installation cost and power cost, bacterial growth and odor caused by condensation, difficulty in maintenance and management cost increase, and the need for a separate installation space can be caused.

Ultraviolet rays (UltraViolet rays) refer to electromagnetic waves with a wavelength of 100 to 380nm (1nm = 10-9m) as a part of electromagnetic waves. Depending on their wavelength, ultraviolet A (315 to 380nm), ultraviolet B (280 to 315nm), and ultraviolet C It can be divided into (100~280nm). In particular, ultraviolet C can be divided into extreme ultraviolet rays, ozone generation rays and sterilization rays. Ultraviolet wavelength, which has a sterilizing effect against microorganisms such as bacteria, mold and yeast, is 250 to 260 nm, and among them, the wavelength of 253.7 nm has the greatest sterilization effect. Sunlight contains a lot of ultraviolet rays, and it is known that ultraviolet rays have the effect of killing bacteria, fungi, and yeast.
