Abstract

PROBLEM TO BE SOLVED: To obtain an air purifier unnecessary in power for convection and small in the problem of the installed position. SOLUTION: The air purifying method is by allowing the air circulating by heat convection caused by an electric lamp 10 to contact with a purifying agent/a purifying tool by film forming the purifying agent on the surface of 14 of the electric lamp 10 and the inside surface 12 of a shade and providing the purifying agent 6 or the purifying tool in the shade 11 of the electric lamp, a shade cover 13 or a mount 3. As a result, even if the purifier is made large sized, the problem of the installed position is eliminated and since the lighting is arranged in the chamber in nearly uniform state, excellent depolluting efficiency is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shade, a shade cover, a mount, and a light bulb for purifying air using a cleaning agent and / or a cleaning tool by utilizing heat convection caused by an electric lamp.

[0002]

SUMMARY OF THE INVENTION Body odor, tobacco odor,
Gases that cause discomfort or are harmful to health, such as formaldehyde emitted from farts or furniture using new building materials, are present in the room. An air purifier is used to remove these unpleasant gases and create a comfortable space. The air purifier required power for convection, and it was necessary to secure an installation place.

[0003]

2. Description of the Related Art Unpleasant gases are mostly combustible gases and are removed by combustion / oxidation. Various detergents and purifiers are used to remove unpleasant gases in the air. Many of these take advantage of this property. As detergents that need to be replaced or replenished regularly, adsorbents such as molecular sieves and activated carbon, surfactants marketed as deodorants and deodorants, aluminum chlorides and bases marketed as flavonoids and deodorants Chemical agents such as conductive aluminum compounds. The adsorbent can also remove non-combustible and unpleasant gases. Catalysts that can be used semipermanently include catalysts such as platinum, palladium, and titanium oxide. Catalytic agents decompose substances with positive heat of formation, such as nitrogen oxides, and oxidize combustible gases to eliminate them. Catalysts such as platinum and palladium are more effective at higher temperatures than at room temperature. Titanium oxide activates oxygen adsorbed on the surface with ultraviolet rays, increasing the extinction power of combustible gases. Many other substances exhibiting catalytic action are also known and are applied to the chemical industry, automotive catalytic converters, etc. The main agent of the gas mask is also a detergent. Purifiers that oxidize unpleasant gases and purify air with silent discharge can be made lightweight and compact, and are used as detergents.

[0004] Semi-permanent cleaning agents and cleaning equipment also require regular cleaning. For this reason, detergents that are regularly replaced or replenished are preferred.

[0005] The absolute amount of unpleasant gases to be removed is by no means large. Therefore, the energy required to remove unpleasant gases is small. Cleaning the entire room requires air circulation and proper placement. In the case of a single unit, it would be good if it could be installed in the center of the room, but it would impair the convenience of the room. In order to be effective in the corner, you need a blower. Decentralized installation also restricts human behavior, and it is not easy to secure installation locations.

[0006]

[Means for Solving the Problems] When arranging one electric light, it is usually almost in the center of the room. When arranging a large number of lights, it is common to have them evenly in the room. This condition is an ideal configuration for air purifier placement. Lights are usually located outside the space where people operate,
It does not get in the way. An electric light is composed of a light bulb, a mount, and a shade. The shade can be decorated with a shade cover (Fig. 2). Attaching a cleaning agent (cleaning agent, cleaning tool) to these can solve the problem both in placement and in securing the installation place. Many shades and mounts are large, in which case the amount of detergent can be increased. Detergents that have a flat plate-like shape will diffuse air better and become more effective than a lump-like detergent. In terms of shape, shades and shade covers are optimally shaped.

There are incandescent lamps, halogen lamps, discharge lamps (fluorescent lamps, sodium lamps, neon lamps, mercury lamps, arc lamps, etc.). Even light bulbs with high light efficiency, such as fluorescent lamps, generate heat and generate air convection.
Therefore, simply placing an object (cleaning agent, etc.) that cleans the air around the lamp eliminates the need for convective power. The heat is efficiently collected by the heat convection caused by the light bulb and around the cleaner to purify the air. The temperature around the light is higher than the surroundings, which is convenient for catalysts. In particular, light bulb surfaces are advantageous at high temperatures.

[0008] Incandescent bulbs emit weak ultraviolet light together with blue light. Discharge lamps such as fluorescent lamps and mercury lamps and halogen lamps emit ultraviolet light that is stronger than incandescent bulbs. With the exception of special lamps such as UV lamps / germicidal lamps, UV light from the lamps is much weaker than sunlight and has no effect on the human body. The catalytic effect of titanium oxide etc. is high on the surface of the bulb, the inside of the shade, and the illuminated surface of the mounting base.

For silent discharge, a high voltage is applied to a pair of electric wires or a parallel metal wire formed on a ceramic surface. The amount of unpleasant gas to be removed is small per hour, requires less power, and requires less power. The functional part has a simple structure, and fits in the space for the detergent together with the power supply part. Therefore, bulbs, shades, shade covers,
By attaching a cleaning agent (cleaning agent, cleaning tool) to the mounting base, an energy-saving and efficient air purifier can be made. Silent discharge and ultraviolet light + titanium oxide film have a bactericidal effect, and can reduce germs floating in the air.

BEST MODE FOR CARRYING OUT THE INVENTION A detergent in the form of granules can be placed in a container, a non-flammable bag, and installed on a mounting base, a shade, and a shade cover. Granules can be made finer and mixed with foams such as rubber for molding. Molecular sieves can also be molded. What can be molded can be used as a shade, a shade cover or a part of them. Liquids can be put in containers, mixed with rubber, or impregnated in porous ceramics, and used like granules. Catalysts such as platinum can be supported on transparent or translucent porous ceramics.
It can also be used by supporting it on metal, glass, ceramics and other inorganic materials by vapor deposition, plating, baking, etc.
Thin films do not impair light transmission. Therefore,
In addition to being able to be installed as granules, it can be molded into shades and shade covers, and can form a film on the surface of light bulbs, shades, and mounts. Titanium oxide is deposited on the surface of the bulb, the inside of the shade, and the illuminated surface of the mounting base. Shades, shade covers, and mounting bases should have good ventilation and air diffusion. For this purpose, ventilation holes and air diffusion holes are provided that can escape vertically.
