Air conditioner for vehicle use

Abstract

Both an air mixing door ( 9 ) for the cold air for adjusting a passage area of the cold air passage ( 6 ); and an air mixing door ( 10 ) for the hot air for adjusting a passage area of the hot air passage ( 7 ) are composed of a sliding door for adjusting the passage area when the air mixing door ( 9 ) for the cold air and the air mixing door ( 10 ) for the hot air are slid in a direction perpendicular to the flow of air in both the passages ( 6, 7 ), and while one of the air mixing door ( 9 ) for the cold air and the air mixing door ( 10 ) for the hot air is maintaining one of the passages ( 6, 7 ) in a fully opened state, an operating position of the other door is adjusted so that a passage area of the other passage is adjusted and a temperature of the air blowing out into a vehicle compartment is adjusted.

1 . An air conditioner for vehicle use comprising: 
 a cold air passage ( 6 ) in which a cold air flows;    a hot air passage ( 7 ) in which a hot air flows;    an air mixing door ( 9 ) for the cold air for adjusting a passage area of the cold air passage ( 6 ); and    an air mixing door ( 10 ) for the hot air for adjusting a passage area of the hot air passage ( 7 ),    wherein    both the air mixing door ( 9 ) for the cold air and the air mixing door ( 10 ) for the hot air are composed of a sliding door for adjusting the passage area when the air mixing door ( 9 ) for the cold air and the air mixing door ( 10 ) for the hot air are slid in a direction perpendicular to the flow of air in both the passages ( 6 ,  7 ), and    while one of the air mixing door ( 9 ) for the cold air and the air mixing door ( 10 ) for the hot air is maintaining one of the passages ( 6 ,  7 ) in a fully opened state, an operating position of the other door is adjusted so that a passage area of the other passage is adjusted and a temperature of the air blowing out into a vehicle compartment is adjusted.    
     
     
         2 . An air conditioner for vehicle use according to  claim 1 , wherein 
 a maximum cooling state is set when the cold air passage ( 6 ) is fully opened by the air mixing door ( 9 ) for the cold air and the hot air passage ( 7 ) is fully closed by the air mixing door ( 10 ) for the hot air,    a maximum heating state is set when the cold air passage ( 6 ) is fully closed by the air mixing door ( 9 ) for the cold air and the hot air passage ( 7 ) is fully opened by the air mixing door ( 10 ) for the hot air, and    a state in which both passages are simultaneously fully opened, in which the cold air passage ( 6 ) is fully opened by the air mixing door ( 9 ) for the cold air and the hot air passage ( 7 ) is fully opened by the air mixing door ( 10 ) for the hot air, is set in an intermediate temperature control region formed between the maximum cooling state and the maximum heating state.    
     
     
         3 . An air conditioner for vehicle use according to  claim 1 , wherein the sliding door composing the air mixing door ( 9 ) for the cold air or the air mixing door ( 10 ) for the hot air is composed of a flexible thin film member ( 9   a ,  10   a ).  
     
     
         4 . An air conditioner for vehicle use according to  claim 3  wherein, when one end portion of the thin film member ( 9   a ,  10   a ) is fixed and the other end portion of the thin film member ( 9   a ,  10   a ) is moved in a direction so that the other end portion can be separated from or come close to one end portion, the length of the thin film member ( 9   a ,  10   a ) from one end portion in the opening portion of the cold air passage ( 6 ) or the hot air passage ( 7 ) is changed, and the passage area of the cold air passage ( 6 ) or the hot air passage ( 7 ) is changed.  
     
     
         5 . An air conditioner for vehicle use according to  claim 4  wherein, when the other end portion of the thin film member ( 9   a ,  10   a ) is connected to the winding shaft ( 9   c ,  10   c ) and the winding shaft ( 9   c ,  10   c ) is moved being rotated in a direction so that the winding shaft ( 9   c ,  10   c ) can be separated from, or come close to, one end portion of the thin film member ( 9   a ,  10   a ), the other end portion of the thin film member ( 9   a ,  10   a ) is wound by the winding shaft ( 9   c ,  10   c ) or leaves the winding shaft ( 9   c ,  10   c ).
