Description

Air sterilizer and deodorizer {Air cleaner}

The present invention relates to an air sterilization and deodorization apparatus, and more particularly, to an air sterilization and deodorization apparatus, and more particularly, to an air sterilization and deodorization apparatus, and more particularly to an air sterilization and deodorization apparatus, To an air sterilizing and deodorizing machine configured to enable deodorization.

While the quality of life is improving day by day as the various industrial technologies are developed and the economic environment is improved, various environmental conditions and conditions around them are getting worse.

 Especially, as the industrial development accelerates, the quality of the atmosphere is deteriorating rapidly. In developed countries, the manufacturing industries that have a great impact on environmental pollution have been transferred to the backward countries.

However, environmental pollutants that pollute the atmosphere are not limited to a single country due to the fact that they move along the wind regardless of the border, and thus affect other neighboring countries and other continents. Therefore, It has become a common concern that countries have to deal with jointly.

Moreover, the air contains not only pollution pollutants emitted from various factories but also various kinds of pathogenic bacteria propagating the disease, so that it infects livestock or human body during respiration to cause various diseases, Is often caused.

As the severity of such air pollution arises, it is impossible to live with the windows open, and various indoor air pollution remedies have been developed or installed to purify contaminated air in enclosed rooms. to be.

Therefore, in the case of a large commercial building in recent years, an air purifier is installed in the entire building so that the air purifier can be operated according to the degree of pollution by measuring the air pollution degree in the building construction, However, it is impossible to manage the air polluted by the integrated system in buildings or homes that have been built long ago. Therefore, air purifiers are separately purchased and used in the room.

Such an air purifier is developed and used in a wide variety of types and forms such as the type of filter used, the type of catalyst used, and the air flow induction method.

The present invention provides an air purifier using an ultraviolet lamp and a photocatalyst. Hereinafter, conventional technologies will be described only in the technical field to which the present invention belongs.

A purification device for sterilizing and deodorizing by a hydroxide radical generated by irradiating ultraviolet rays to a photocatalyst material is not only a well-known technology but also widely used in various industrial fields.

Among them, a water and air purification device using a spiral photocatalytic plate of Korean Registered Utility Model No. 20-254611 (registered on November 11, 2001) has been known as a conventional example.

The 'water and air purification apparatus using a spiral photocatalytic plate' according to the above-described conventional example has a structure in which a photocatalytic plate is continuously and spirally connected and is inserted into an ultraviolet lamp, and is installed inside a case having an inlet and an outlet at both ends, And the air can be purified while being moved along a spiral space portion formed between the photocatalyst plates.

However, the conventional water and air purifying apparatus using the photocatalytic plate has a disadvantage in that the water and air, which are the purified water, go out at right angles to the spirally formed photocatalytic plate, and the purification efficiency of the target object per unit time is comparatively low. The photocatalytic coating surface for decomposing harmful substances through the photoreaction is located in a direction perpendicular to the ultraviolet lamp, and the ultraviolet absorption effect of the photocatalyst coating surface is low, so that it is difficult to maximize the purification efficiency of the epitaxial layer.

As another conventional example, Korean Patent Registration No. 10-718676 (Registered on May 05, 2007) discloses a device for purifying a water sterilization using a photocatalytic bead body.

The water sterilization and purification device is provided with a spiral tube through which wastewater passes through between an inflow frame and an outflow frame through which wastewater flows in and out, and a bead body coated with a photocatalyst is inserted into the spiral tube so as to be in contact with wastewater And a plurality of ultraviolet rays generating means for irradiating the ultraviolet rays toward the spiral tube are provided at the center of the spiral tube to sterilize and purify various harmful substances contained in the wastewater.

However, the conventional sterilizing apparatus for water sterilization has a complicated structure and structure, and its manufacturing process is also very difficult, and its volume is so large that it is somewhat difficult to use it in a miniaturized air purification apparatus.

In another conventional example, a spiral photocatalytic plate having a plurality of lamps was found in Korean Patent Registration No. 10-1220870 (registered on Apr. 31, 2013).

In the case of the 'helical photocatalytic plate on which a plurality of lamps are installed' as well, a plurality of photochemical reaction lamps are installed in the central part and the periphery of one photocatalytic plate, so that the contaminated gas and the liquid react at a closer distance, So that it can be increased.

However, as in the above-described conventional example, the contaminated gas or liquid is configured to move in a direction perpendicular to the installation direction of the spiral photocatalytic plate, thereby increasing the time and area in which the projected body is in contact with the surface of the photocatalytic plate However, since the moving speed of the gas or liquid is disturbed by the photocatalyst plate, the cleaning efficiency per unit time is not high due to the movement at a very low speed, and the photochemical reaction lamp and the photocatalyst plate are arranged at right angles, And the cleaning ability of the contaminated gas or liquid is not relatively high.
