Louver structure of air conditioner for a bus

Abstract

A louver structure of an air conditioner for a vehicle is provided that can enable a passenger to control the direction and the amount of cooling air discharged from an air conditioner as desired. By the louver structure, when the passengers do not want the cooling air to be in direct contact with their bodies, it is possible to convert the direction of discharging the cooling air in an alternate direction as well as improve a cooling effect within the vehicle.

 a louver body for discharging cooling air supplied through a duct, the louver body being installed in the duct arranged in the bus and having thru-holes formed in the louver body;    air control plates respectively installed in each thru-hole of the louver body and having a first air discharging portion in order to discharge the cooling air;    air control housings fixedly installed to the louver body and respectively having a second air discharging portion;    knobs installed under the air control plates respectively, and each knob including a control portion having one end directed downward in order for a user to easy operate the knob and the other end extending through the air control plate and a center of the air control housing to an interior of the louver body;    air control cap respectively installed to the other end of the control portion; and    air control conversion portions installed to the air control housings respectively, and each of which has a flowing hole formed at a center portion of the air control conversion portion for discharging the cooling air vertically and a guide portion formed around the flowing hole for discharging the cooling air horizontally.    
   
   
       2 . The louver structure of an air conditioner for a bus of  claim 1 , wherein the louver body has respective mounting clips to be in close contact with an inner periphery of each thru-hole.  
   
   
       3 . The louver structure of an air conditioner for a bus of  claim 1 , wherein the air control plates includes a coupling hole through which the one end of the control portion of each knob extends, and the first air discharging portion formed around the coupling hole including first air discharging holes which are radially and outwardly formed around the coupling hole, for passing the cooling air through the first air discharging holes in a vertically downward direction, and second air discharging holes which are radially and outwardly formed around the first air discharging holes, for passing the cooling air through the second air discharging holes in a horizontal direction.  
   
   
       4 . The louver structure of an air conditioner for a bus of  claim 1 , wherein the first air discharging holes of each air control plate are respectively formed at each one third position between the second air discharging holes.  
   
   
       5 . The louver structure of an air conditioner for a bus of  claim 3 , wherein depression grooves are outwardly formed at the coupling hole.  
   
   
       6 . The louver structure of an air conditioner for a bus of  claim 1 , wherein each air control housing includes an insertion hole in which the one end of the control portion of each knob, and the second air discharging portion formed around the insertion hole including third air discharging holes formed radially and outwardly around the insertion hole, for passing the cooling air through the third air discharging holes in a vertically downward direction, fourth air discharging holes formed radially and outwardly around the third air discharging holes, for passing the cooling air through the fourth air discharging holes in a horizontal direction, and a mounting groove depressed in the air control housing so that the air control conversion portion is installed.  
   
   
       7 . The louver structure of an air conditioner for a bus of  claim 6 , wherein the third air discharging holes are formed at two third positions between the fourth air discharging holes.  
   
   
       8 . The louver structure of an air conditioner for a bus of  claim 6 , wherein the air control housing has mounting holes through which coupling screws extend in order to fix the air control housing to mounting clips of the louver body.  
   
   
       9 . The louver structure of an air conditioner for a bus of  claim 1 , wherein each knob including a housing portion installed to the control portion, and which has a hemispheric shape with an upper portion of the housing portion opened and has a plurality of though-holes, latching protrusions which are latched in latching grooves of the air control plate to which the control portion is coupled, and a supporting plate formed below the latching protrusions, which is in surface contact with a lower surface of the air control housing so that the latching protrusions are inserted in the latching grooves of the air control plate.  
   
   
       10 . The louver structure of an air conditioner for a bus as claimed in  claim 1 , wherein the control portion has a first screw thread formed at the other end of the control portion.  
   
   
       11 . The louver structure of an air conditioner for a bus as claimed in  claim 1 , wherein the air control cap has a second screw thread formed on an inner peripheral surface of the air control cap in order to assemble the air control cap with the other end of the control portion.  
   
   
       12 . A louver structure of an air conditioner for a vehicle, comprising: 
 a louver body for discharging cooling air supplied through a duct and comprising one or more apertures;    one or more air control plates positioned in coordination with one or more apertures of the louver body and comprising a first air discharging portion in order to discharge the cooling air;    one or more air control housings positioned in coordination with the louver body and comprising a second air discharging portion; and    one or more adjustment controls that can be accessed by a vehicle passenger.    
   
   
       13 . The louver structure of  claim 12  further comprising an air control cap.  
   
   
       14 . The louver structure of  claim 12  further comprising air control conversion portions installed to the air control housings.  
   
   
       15 . The louver structure of  claim 14  wherein one or more air control conversion portions comprises a flowing hole for discharging the cooling air vertically and a guide portion for discharging the cooling air horizontally.  
   
   
       16 . The louver structure of  claim 12  wherein the louver body is installed in the duct arranged in the vehicle.  
   
   
       17 . A motor vehicle comprising a louver structure of  claim 1 .
