Air conditioner for vehicle

1. An air conditioner for a vehicle, which includes: an air-conditioning case having an air passageway for connecting an air inflow port and an air outflow port with each other; an evaporator and a heater core mounted on the air passageway; a blower unit disposed at the side of the air inflow port to blow air to the inside of the air-conditioning case; and a separator disposed at the upstream side of the evaporator to divide air, which is introduced into an air inflow passageway of the air-conditioning case, into the right and the left, the air conditioner comprising:

an assembly end portion disposed at an end portion of an upper side of the separator to be inserted and assembled on the air inflow passageway of the air-conditioning case by forced fitting,

wherein the assembly end portion is formed by insert-molding elastically transformable material to the separator and

wherein the assembly end portion comprises: an insertion portion horizontally inserted into the air inflow passageway; and a stepped portion which is bent several times from an end portion of one side of the insertion portion downwardly and forwardly to form a stair shape.

2. The air conditioner according to claim 1 , wherein the assembly end portion gets in close contact with an inner surface of the air inflow passageway to form a sealing structure.

3. The air conditioner according to claim 1 , wherein the air-conditioning case has a fixing groove formed on the side corresponding to the assembly end portion so that the separator is fit and inserted thereinto.

4. The air conditioner according to claim 1 , wherein the stepped portion has a tapered portion to guide insertion of the assembly end portion by an inclined surface when the assembly end portion is inserted into the air inflow passageway.

5. The air conditioner according to claim 1 , wherein volumes of air passing through left and right air passageways of the air-conditioning case are controlled separately, so that a driver's seat space and a passenger's seat space of the vehicle are cooled and heated separately.

6. The air conditioner according to claim 1 , further comprising:

a sealing part disposed between the separator and the evaporator to seal between the separator and the evaporator,

wherein the sealing part is compressed to tubes of the evaporator to seal between the evaporator and the separator.

7. The air conditioner according to claim 6 , wherein the sealing part comprises:

an elastic sealing member made of elastically transformable material and getting in contact with the evaporator; and

a compression support part extending from an end portion of the separator to compress and support the elastic sealing member.

8. The air conditioner according to claim 7 , wherein the elastic sealing member has a curved portion, and its longitudinal direction is parallel with the longitudinal direction of the tubes, and

wherein the compression support part elastically transforms the elastic sealing member so that the elastic sealing member comes in surface contact with the tubes.

9. The air conditioner according to claim 7 , wherein the compression support part surrounds and supports the circumference of a rear part of the elastic sealing member, and

wherein an end portion of the compression support part is arranged to be spaced apart from the evaporator.

10. The air conditioner according to claim 7 , wherein the compression support part comprises:

a first protrusion protruding from a base formed at an end portion of the separator; and

a second protrusion formed to be spaced apart from the first protrusion at a predetermined interval to compress and support both sides of the elastic sealing member together with the first protrusion.

11. The air conditioner according to claim 10 , wherein the first and second protrusions are formed in the plural in the vertical direction of the separator, and are forcedly inserted and fitted between pins of the evaporator.

12. The air conditioner according to claim 10 , wherein the elastic sealing member is formed on the compression support part by insert-molding.

13. The air conditioner according to claim 10 , wherein the compression support part has a protrusion portion, which protrudes outwardly from the both end portions of the elastic sealing member in the longitudinal direction, to prevent the both end portions of the elastic sealing member from getting in contact with an inner surface of the air-conditioning case when the assembly end portion is inserted into the air inflow passageway.

14. The air conditioner according to claim 10 , wherein the elastic sealing member is made of a waterproof material to prevent permeation of condensate water of the evaporator.
