Description

Photocatalytic device using a reflector and air purifying device using the same {{PHOTOCATALYST APPARATUS USING A REFLECTOR AND AIR PURIFICATION APPARATUS USING THE SAME}

In general, indoors are contaminated faster than outside air because they are enclosed spaces. In other words, while outside air is polluted, the rate of natural purification is large, while bets are polluted faster than outside air because they continue to circulate in confined confined spaces, and they cause more serious harm than contaminated outside air because the contaminated bets continue to circulate. There is a lot of concern. As a result, the room is a confined space if not frequently ventilated, so it is also a place to cause contamination of bacteria, odors and mite habitats.

In addition, the sealing degree is increasing to increase the effect of insulation, cooling, sound insulation, etc. due to the change in the residential style, and the emission of pollutants is further increased with the emergence of new building materials for energy conservation.

Therefore, recently, various air purifiers have been developed and marketed to sterilize and deodorize polluted air, and to decompose harmful substances contained in the air and to discharge clean air. Such air purifiers are being combined with various devices such as hot and cold air conditioners and air conditioners. The air purifier is a case having an air inlet and outlet and an air fan that rotates by supplying power from the power supply and the power supply to suck air through the air inlet and discharge the air to the air outlet, and emits ultraviolet rays when the power is applied. Photocatalyst device which sterilizes and deodorizes the polluted air which is sucked by the air fan by using an ultraviolet light lamp and photooxidation reaction between the ultraviolet light and the photocatalyst to be discharged through an air outlet and generates ions for decomposing harmful substances It consists of.

FIG. 1 is a view showing a conventional photocatalyst device. Hereinafter, a configuration of a photocatalyst device, which is an important device of an air purifier, and air sterilization, deodorization, and decomposition of harmful substances will be described with reference to FIG. 1.

In addition, there is a problem that can cause environmental pollution by increasing the number of special fiber bag discarded by discarding the photocatalyst bag can be used more unnecessarily.

In addition, when the air purifying device is a cold / hot air device, the photocatalyst device is directly fitted with cold air by heat exchange of the cold / hot air device, and condensation may occur due to the difference between the temperature of the ultraviolet lamp and the temperature of the cold air. That is, there was a problem that the life of the photocatalytic bag due to hot air can be shortened.

In addition, the conventional air purifying device generates ions only by the photocatalyst coated on the inside of the photocatalyst bag, so there is a problem that the amount of generated ions is small.
