Air conditioner for a vehicle

Abstract

Provided is an air conditioner for a vehicle, which has an improved condensate discharging structure so as to prevent condensate from being leaked through a divided surface of a left and right divided type air conditioning case. To this end, a condensate discharging port is formed at a lower side of an evaporator of the first and second cases, and a partition wall is formed from a lower side of a drain passage to an upper side thereof so that the condensate is flowed through the condensate discharging passage without a leakage of the condensate.

 an evaporator; and   an air conditioning case which is comprised of a first case and a second case, which the evaporator is installed in an inner space of the air conditioning case;   wherein the first case comprises (a) a main drain passage which is provided with (1) a first side wall which is protruded to a lower side of the bottom surface of the first case, (2) a first bottom wall which is connected with the first side wall and (3) a first partition wall which is spaced apart from the first side wall and protruded to an upper side of the first bottom wall, and (b) a first condensate discharging passage which is formed to be communicated with the main drain passage, and   the second case comprises (a) a sub-drain passage which is provided with (1) a second side wall which is protruded to the lower side of the bottom surface of the second case, (2) a second bottom wall which is connected with the second side wall and (3) a second partition wall which is spaced apart from the second side wall, protruded to an upper side of the second bottom wall and jointed to the first partition wall, and (b) a second condensate discharging passage which is formed to be communicated with the sub-drain passage, and   a condensate discharging port is formed at a bottom surface of the first case and/or a bottom surface of the second case so as to guide condensate generated from the evaporator to the main drain passage and/or the sub-drain passage.   
   
   
       2 . The air conditioner of  claim 1 , wherein a bent portion is formed at one of the first and second partition walls so as to cover an upper surface of the other partition wall. 
   
   
       3 . The air conditioner of  claim 2 , wherein a length of the bent portion is formed to be larger than a sum of thicknesses of the first and second partition walls. 
   
   
       4 . The air conditioner of  claim 1 , wherein upper ends of the first and second partition wall are contacted with each other and bent toward the sub-drain passage. 
   
   
       5 . The air conditioner of  claim 1 , wherein an upper end of the first partition wall is formed to be more protruded upward than an upper end of the second partition wall. 
   
   
       6 . The air conditioner of  claim 1 , wherein the condensate discharging port is formed by inwardly concaving a part of a joint portion of the bottom surface of the first or second case. 
   
   
       7 . The air conditioner of  claim 6 , wherein the condensate discharging port is provided in plural along the joint portion of the bottom surface of the first or second case so as to smoothly discharge the condensate even when the air conditioning case is inclined during movement of a vehicle. 
   
   
       8 . The air conditioner of  claim 6 , wherein a center portion of the condensate discharging port is spaced apart in a predetermined distance from the bonded surface of the first and second partition walls toward the main drain passage. 
   
   
       9 . The air conditioner of  claim 1 , wherein the main and sub-drain passages are downwardly inclined toward the first and second condensate discharging passage. 
   
   
       10 . The air conditioner of  claim 9 , wherein the first and second condensate discharging passages are formed as semi-divided bodies so as to form a single drain pipe after they are coupled with each other. 
   
   
       11 . The air conditioner of  claim 9 , wherein a partition is formed at the joint portion of the first and second condensate discharging passages so as to partition each of the main and sub-drain passages. 
   
   
       12 . The air conditioner of  claim 1 , wherein a first groove is formed at a lower side of one of the first or second bottom wall, and a first protrusion that is inserted into the first groove is also formed at a lower side of the other bottom wall. 
   
   
       13 . The air conditioner of  claim 12 , wherein second and third grooves are formed at the bottom surface of one of the first and second cases, and second and third protrusions which are respectively inserted into the second and third grooves are formed at the bottom surface of the other case. 
   
   
       14 . An air conditioner for a vehicle, comprising:
 an air conditioning case which is comprised of a first case  1000   a  and a second case; and   an evaporator which is installed in an inner space of the air conditioning case,   wherein a condensate discharging port is formed at a bottom surface of the first or second case, and a main drain passage and a sub-drain passage that are communicated with an inner space of the air conditioning case, in which the evaporator is installed, and partitioned by a partition wall are formed so as to guide condensate discharged through the condensate discharging port to an outside, and   a center portion of the condensate discharging port is spaced in a predetermined distance apart from a center line of the partition wall.   
   
   
       15 . The air conditioner of  claim 14 , wherein the partition wall is comprised of a first partition wall of the main drain passage and a second partition wall of the sub-drain passage, and one of the first and second partition wall has a bent portion so as to cover an upper surface of the other partition wall. 
   
   
       16 . The air conditioner of  claim 14 , wherein the main drain passage and the sub-drain passage are formed to be respectively communicated with the first and second condensate discharging passage so that the condensate is discharged to an outside of the air conditioning case. 
   
   
       17 . The air conditioner of  claim 16 , wherein a partition is formed at a joint portion of the first and second condensate discharging passages so as to partition the main drain passage and the sub-drain passage.
