Purifying air conditioner

Abstract

An air conditioning system has a negative ion-filtering device in union for purifying function which comprises a PC board to produce negative ions, a high voltage lead, high voltage electric sheets, and a dust mesh, being positioned in the air blow direction path of the air conditioner for use after the temperature adjustment is made. Electric sheets which produce negative ions make the passing dust particles of the air carry negative charges and be sucked attached to the dust mesh producing positive ions, this way achieving purification of the air passing there-through.

I claim: 
     
       1. An improved air conditioner for purifying air by removing dust particles therefrom, comprising: a negative ion-filtering device disposed behind an air blow direction regulating grill of a front upper face of said air conditioner, said negative ion-filtering device comprising high voltage leads connecting a PC board to high voltage electric sheets in order to cause production of negative ions and a positive charge providing dust collecting mesh disposed between said high voltage electric sheets to cause floating dust particles in air passing after temperature adjustment to carry negative charges so that negative charged floating dust particles are sucked in attachment to said positive charged dust mesh, charged and any dust particles passing said positive charged dust mesh are negatively charged and allowed to fall in attachment to positive ground charges as the air exits the air blow regulating grill. .Iadd.2. An improved air conditioning system for purifying air by removing dust particles therefrom, comprising in combination: a negative ion-filtering device disposed within the air blow direction path of said air conditioning system after the air has been treated for changing its temperature, said negative ion-filtering device comprising high voltage leads connecting a PC board to high voltage electric sheets in order to cause production of negative ions and a positive charge providing dust collecting mesh disposed between said high voltage electric sheets to cause floating dust particles in air passing after temperature adjustment to carry negative charges so that negative charged floating dust particles are drawn into attachment to said positive charged dust mesh, and any dust particles passing said positive charged dust mesh are negatively charged and allowed to fall in attachment to positive ground charges as the air exits the air conditioning system. .Iaddend. .Iadd.3. An improved air conditioner as in claim 2, for purifying air by removing dust particles therefrom, comprising in combination: a negative ion-filtering device disposed within the air blow direction output of said air conditioner, said negative ion-filtering device comprising high voltage leads connecting a PC board to high voltage electric sheets in order to cause production of negative ions and a positive charge providing dust collecting mesh disposed between said high voltage electric sheets to cause floating dust particles in air passing after temperature adjustment to carry negative charges so that negative charged floating dust particles are drawn into attachment to said positive charged dust mesh, charged, and any dust particles passing said positive charged dust mesh are negatively charged and allowed to fall in attachment to positive ground charges as the air exits the air blow regulating grill. .Iaddend. .Iadd.4. An air conditioning system as in claim 2 for purifying air by removing dust particles therefrom, comprising in combination: a negative ion-filtering device disposed within the air blow direction path of said air treatment system after the air has been treated for changing its temperature, said negative ion-filtering device comprising high voltage leads connecting a PC board to high voltage electric sheets in order to cause production of negative ions and a positive charge providing dust collecting mesh disposed between said high voltage electric sheets to cause floating dust particles in air passing after temperature adjustment to carry negative charges so that negative charged floating dust particles are drawn into attachment to said positive charged dust mesh, and any dust particles passing said positive charged dust mesh are then negatively charged and allowed to fall in attachment to positive ground charges as the air exits the air conditioning system. .Iaddend.
