Air cleaner

Abstract

According to one embodiment of the present disclosure, an air cleaner includes a first air purification module, a second air purification module, and a control module disposed between the first air purification module and the second air purification module, in which the control module includes an upper cover, a lower cover, a substrate accommodated in an internal space formed by coupling the upper cover and the lower cover, and a plate supporting the substrate from below, in which a drain hole is formed in the lower cover, and the plate includes a drain guide that guides water flowing into the control module to the drain hole, thereby protecting the internal substrate and components even when water flows into the control module.

What is claimed is: 
     
         1 . An air cleaner comprising:
 a case having an intake port formed on a peripheral surface;   a first air purification module including a first blower fan disposed inside the case and a first filter for removing foreign substances in air flowing into the intake port;   a second air purification module including a second blower fan disposed inside the case and a second filter for removing foreign substances in air flowing into the intake port; and   a control module disposed between the first air purification module and the second air purification module,   wherein the control module includes an upper cover, a lower cover, a substrate accommodated in an internal space formed by coupling the upper cover and lower cover, and a plate supporting the substrate from below,   a drain hole is formed in the lower cover, and   the plate includes a drain guide for guiding water flowing into the control module to the drain hole.   
     
     
         2 . The air cleaner of  claim 1 , wherein the lower cover includes a base having an open center and a lower filter pressing plate disposed at the center of the base, and
 the drain hole is formed in the base.   
     
     
         3 . The air cleaner of  claim 2 , wherein the lower cover further includes a lower seating portion including an inclined surface that guides water passing through the drain guide to the drain hole. 
     
     
         4 . The air cleaner of  claim 3 , wherein the lower cover includes
 a first inclined surface whose part is positioned on one side of the drain guide,   a first flat surface extending outward from a lower end of the first inclined surface, and   a second inclined surface extending from the first flat surface.   
     
     
         5 . The air cleaner of  claim 4 , wherein the first flat surface is positioned below an outlet of the drain guide. 
     
     
         6 . The air cleaner of  claim 4 , wherein the lower cover includes a second flat surface positioned between the second inclined surface and the drain hole. 
     
     
         7 . The air cleaner of  claim 6 , wherein the lower cover further includes left and right baffles in contact with the first inclined surface, the first flat surface, the second inclined surface, and the second flat surface. 
     
     
         8 . The air cleaner of  claim 1 , wherein the drain guide includes
 an upper guide having an inlet formed at an upper end, and   a lower guide having an outlet formed at a lower end.   
     
     
         9 . The air cleaner of  claim 8 , wherein the lower guide includes a section in which an opening area gradually decreases toward a lower side. 
     
     
         10 . The air cleaner of  claim 1 , wherein the upper cover includes a channel guide whose part is inserted into the drain guide. 
     
     
         11 . The air cleaner of  claim 10 , wherein the upper cover includes a body having an open center and an upper filter pressing plate positioned at the center of the body, and
 the channel guide is formed in the body.   
     
     
         12 . The air cleaner of  claim 11 , wherein the channel guide includes
 a first guide extending downward from the body, and   second and third guides extending outward from the first guide.   
     
     
         13 . The air cleaner of  claim 12 , wherein the second and third guides have different shapes. 
     
     
         14 . The air cleaner of  claim 11 , wherein the second air purification module is disposed above the first air purification module,
 a first discharge port is formed at a lower end of the first air purification module, and   a second discharge port is formed at an upper end of the second air purification module.   
     
     
         15 . The air cleaner of  claim 11 , wherein the control module includes
 a plurality of sensors, and   a stand on which the plurality of sensors are mounted, and   the stand is connected to an upper side of the plate.
