Air conditioner for vehicle
The present invention relates to an air conditioner for a vehicle that is capable of easily and simply assembling a thermistor-holding device insertedly with a coupling hole formed at one side surface of a lower case of an air conditioning case, while inserting first and second protrusions formed through upper and lower molds around the coupling hole thereto, such that the total number of parts and the working period are all reduced to improve the productivity of the product and the repairing or exchanging work of the thermistor is carried out easily.
1. An air conditioner for a vehicle comprising:
an air conditioning case formed partitionally of a plurality of pieces to be assembled, and having a coupling hole formed at one side surface thereof and at least one protrusion formed spaced apart from the edge periphery of the coupling hole by a predetermined distance;
an assembling part insertedly assembled with the coupling hole and having an insertion hole formed in the center thereof for inserting a wire connected to a thermistor thereto, wherein the assembling part includes an outside coupler having at least one fastening slot circumferentially formed thereon in such a manner as to be rotated at a state of fittingly inserting the at least one protrusion into the at least fastening slot, a handle grip coupled to the rear side of the outside coupler, and an inside coupler coupled integrally to the front side of the outside coupler in such a manner as to be inserted into the coupling hole and having a locking portion formed along the front end periphery thereof for preventing the assembling part from being escaped from the coupling hole during the rotation at the state of being inserted into the coupling hole; and
a support part coupled to the assembling part in such a manner as to be placed near an evaporator for supporting the wire 81 connected to the thermistor.
2. The air conditioner for a vehicle according to claim 1 , wherein the at least one protrusion is protruded outwardly from the air conditioning case.
3. The air conditioner for a vehicle according to claim 1 , wherein the at least one fastening slots is of an arc shape and has at least one or more elastic pieces on the inner peripheries of the end portions thereof in the rotating direction thereof in such a manner as to be locked to the at least one protrusion, thereby fixing the position of the assembling part to the air conditioning case.
4. The air conditioner for a vehicle according to claim 1 , wherein the inside coupler comprises an insertion portion adapted to be inserted into the inner periphery of the coupling hole and the locking portion formed along the front end periphery of the insertion portion in such a manner as to be locked to the inside of the air conditioning case during the rotation at the state of being inserted into the coupling hole.
5. The air conditioner for a vehicle according to claim 4 , wherein the coupling hole has an extension portion formed along the inner periphery thereof, the extension portion having a shape corresponding to the locking portion of the inside coupler.
6. The air conditioner for a vehicle according to claim 1 , wherein the support part further comprises at least one or more clamps disposed at predetermined intervals therealong for supporting the outer periphery of the wire mounted at the top surface thereof, each of the clamps having a body having an opening adapted to fittably insert the support part thereinto and at least one spaced support projections protruded upwardly from the top end of the opening of the body for supporting the wire connected to the thermistor.
7. The air conditioner for a vehicle according to claim 1 , wherein the air conditioning case is injection-molded through upper and lower molds separated in a direction orthogonal to the coupling hole.
8. The air conditioner for a vehicle according to claim 1 , wherein the handle grip has a concaved groove formed thereon for guiding the wire.
9. The air conditioner for a vehicle according to claim 1 , wherein the at least one protrusion is formed in such a manner as to cross each other.
10. The air conditioner for a vehicle according to claim 5 , wherein so as to prevent the assembling part from being erroneously assembled with the coupling hole, one locking portion is formed along the front end periphery of the insertion portion and one extension portion is formed along the inner periphery of the coupling hole in a corresponding shape to the locking portion.
11. The air conditioner for a vehicle according to claim 5 , wherein so as to prevent the assembling part from being erroneously assembled with the coupling hole, a plurality of locking portions is formed along the front end periphery of the insertion portion, and a plurality of extension portions is formed along the inner periphery of the coupling hole in a corresponding shape to the plurality of locking portions, the plurality of locking portions having different shapes or sizes from one another.
