The present invention relates to a blade socket for an air conditioner built into the ceiling and to a method for manufacturing same. The method comprises: a first copper pipe cutting step (S1) of cutting, into a predetermined length, a first copper pipe, the interior of which has a through-hole for a refrigerant to pass therethrough; a second copper pipe cutting step (S2) of cutting, to a predetermined length, a second copper pipe, the interior of which has through-hole for a refrigerant to pass therethrough, and the diameter of which is smaller than the diameter of the first copper pipe; a first processing step (S3) of processing an end of the first copper pipe into the shape of an end of the blade socket, such that the end of the first copper pipe is formed into a tapered sharp end; a roughening step (S4) of roughening an outer surface of the second copper pipe in order to render the outer surface uneven; a welding step (S5) of inserting the end of the roughened second copper pipe into one side of the first copper pipe, and welding the contact surface between the first copper pipe and the second copper pipe to tightly join the first copper pipe and the second copper pipe, such that the through-holes of the first copper pipe and the second copper pipe are in communication with one another; an insert injection preparing step (S6) of inserting the first and second copper pipes into an insert injection mold assembly having the shape of the blade socket; and an injecting step (S7) of insert-injecting a material onto the outer surfaces of the first and second copper pipes to form a blade socket, such that the sharp end of the first pipe is outwardly exposed, and to obtain a finished product. Further, the present invention relates to a blade socket for an air conditioner built into the ceiling and to a method for manufacturing same. The method for manufacturing a blade socket (210) to be used in an air conditioner built into the ceiling, involves joining a first pipe (211) and a second pipe (212) to form a "?" shape, loading the resultant "?"-shaped structure into a mold, and insert-injecting a synthetic resin into the mold to obtain a blade-shaped injection-molded body (213) covering the first pipe (211) and the second pipe (212). The method comprises insert-injecting an inexpensive resin onto the outer surfaces of pipes, in the interiors of which refrigerant is to flow, to obtain the shape of a blade socket, thereby reducing the costs of products and achieving price competitiveness. |
