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 first substrate and second substrate accommodated in an internal space formed by coupling the upper cover and lower cover, a plate supporting the first substrate and second substrate from below, a first substrate seating portion which protrudes upward from the plate and to which the first substrate is fixed, and a second substrate seating portion which protrudes upward from the plate and to which the second substrate is fixed, and the first substrate is disposed spaced apart from an upper side of the second substrate, thereby effectively disposing components inside 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 first substrate and second substrate accommodated in an internal space formed by coupling the upper cover and lower cover, a plate supporting the first substrate and second substrate from below, a first substrate seating portion which protrudes upward from the plate and to which the first substrate is fixed, and a second substrate seating portion which protrudes upward from the plate and to which the second substrate is fixed, and   the first substrate is disposed spaced apart from an upper side of the second substrate.   
     
     
         2 . The air cleaner of  claim 1 , wherein the plate includes a recessed portion formed to be recessed downward, and
 the second substrate seating portion is formed by protruding upward from the recessed portion.   
     
     
         3 . The air cleaner of  claim 2 , wherein a depth of the recessed portion is smaller than a vertical length of the first substrate seating portion. 
     
     
         4 . The air cleaner of  claim 2 , wherein the first substrate seating portion includes
 a plurality of pillars protruding upward from the plate, and   coupling holes formed on upper surfaces of the plurality of pillars, and   some of the plurality of pillars have different shapes from those of the remaining pillars.   
     
     
         5 . The air cleaner of  claim 2 , wherein the second substrate seating portion includes a plurality of ribs that protrude upward from the recessed portion, a first part that fixes one side of the second substrate, and a second part that extends from some of the plurality of ribs to an upper side of the second substrate. 
     
     
         6 . The air cleaner of  claim 2 , wherein the second substrate seating portion includes a plurality of pillars protruding upward from the recessed portion and coupling holes formed on upper surfaces of the plurality of pillars. 
     
     
         7 . The air cleaner of  claim 1 , wherein the first substrate seating portion includes a plurality of pillars protruding upward from the plate and coupling holes formed on upper surfaces of the plurality of pillars, and
 some of the plurality of pillars have a different shape from the remaining pillars.   
     
     
         8 . The air cleaner of  claim 7 , wherein at least some among the plurality of pillars have a fixed rib protruding upward. 
     
     
         9 . The air cleaner of  claim 1 , wherein the second substrate includes a plurality of substrates disposed spaced apart from each other. 
     
     
         10 . The air cleaner of  claim 9 , wherein at least some of the plurality of substrates overlap the first substrate when viewed from above. 
     
     
         11 . The air cleaner of  claim 9 , wherein at least some of the plurality of substrates partially overlap the first substrate when viewed from above. 
     
     
         12 . The air cleaner of  claim 1 , wherein an area of the first substrate is larger than an area of the second substrate. 
     
     
         13 . The air cleaner of  claim 1 , 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.   
     
     
         14 . The air cleaner of  claim 1 , wherein each of the upper cover and the lower cover has an open center,
 the control module further includes an upper filter pressing plate disposed at the center of the upper cover and a lower filter pressing plate disposed at the center of the lower cover,   the lower filter pressing plate is disposed above the first filter, and   the upper filter pressing plate is disposed below the second filter.   
     
     
         15 . The air cleaner of  claim 1 , 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.
