Definitions

• the present invention relates, in general, to an indoor floating dust collecting apparatus using convection flow, and more particularly, to an indoor floating dust collecting apparatus using convection flow which is installed in a conventional illuminator attached to a ceiling, etc. in a house, an office or the like to suck, remove and deodorize indoor floating dust so that not only an illumination function for optimizing the brightness of an indoor space is rendered under the control of a remote controller, but also convection flow is promoted to effectively filter and collect indoor floating dust, thereby providing pleasant living or working circumstances.
• an air cleaner functions to suck and purify polluted indoor air and to discharge fresh air so that pleasant indoor circumstances can be created. That is to say, in the air cleaner, polluted indoor air is sucked using a fan, and fine dust and bacteria are collected and odors are filtered out by a filter arranged inside the fan so that fresh air can be discharged to an indoor space.
• an anion generator is additionally disposed in the air cleaner to generate anions which are beneficial to human health. That is to say, an air cleaner, which is further upgraded in its functionality in order to effectively reduce damage by harmful indoor substances, has been developed and put on the market.
• Air cleaners are usually divided into a stand type air cleaner or a wall mount type air cleaner. Therefore, in use, an air cleaner is placed at a proper position in a room or is mounted to a wall to be maintained at a height which is separated from a floor by a desired distance.
• the stand type and the wall mount type air cleansers suffer from defects in that they cannot uniformly purify indoor air when they are installed and actuated.
• an air purification range cannot but be limited to a certain extent, so air purification effect gradually decreases in a direction facing away from the wall on which the air cleaner is mounted, whereby air purification cannot be effectively implemented throughout the entire indoor space and thereby air purification capability is degraded.
• an illuminator generally known in the art is installed on a ceiling, etc. in a house, an office or the like to light an indoor space. Since this conventional illuminator simply performs an illumination function, it has limited functionality. Disclosure of Invention Technical Problem
