The configuration in which a separate external refrigerant pipe 9 is jointly connected to the outlet 8 of the outer end of the refrigerant return pipe 7 so that it can be discharged to the outside is the refrigerant pipe connection of the drum rotary ice maker shown in FIGS. 1 and 2 . Since it is applied substantially the same as the device, a detailed description of the configuration thereof is omitted, and overlapping reference numerals mean a configuration (article) having the same function.

따라서, 본 명세서의 바람직한 일 실시예에 의한 드럼 회전식 제빙기용 냉매관 연결장치에 의하면, 전술한 냉매공급관(5) 및 냉매회수관(7)의 금속재로 형성된 흡입구(58) 및 배출구(8)에 알루미늄재로 형성된 외부냉매관(59,9)을 이음연결할 경우, 외부냉매관(59,9)의 스토퍼(61,11) 일측으로 연장형성된 실링재 이탈방지구(66,16)에 오링형태의 실링재(65,15)를 끼운 다음, 외부냉매관(59,9)을 흡입구 (58) 및 배출구(8)의 결합공(62,12)에 삽입시킨다.Therefore, according to the refrigerant pipe connection device for the drum rotary ice machine according to the preferred embodiment of the present specification, the inlet 58 and outlet 8 formed of the metal material of the refrigerant supply pipe 5 and the refrigerant return pipe 7 described above are connected to the When connecting the external refrigerant pipes 59 and 9 formed of aluminum material, an O-ring type sealing material is applied to the sealing material separation prevention holes 66 and 16 extending to one side of the stoppers 61 and 11 of the external refrigerant pipes 59 and 9. After inserting (65, 15), the external refrigerant pipes (59, 9) are inserted into the coupling holes (62, 12) of the inlet (58) and the outlet (8).

또는, 전술한 흡입구(58) 및 배출구(8)의 결합공(62,12) 내주연에 형성된 걸림턱(63,13)에 실링재(65,15)를 먼저 안착시킨 후, 외부냉매관(59,9)을 결합공(62,12)에 삽입시킬 경우 외부냉매관(59,9)의 실링재 이탈방지구(66,16)가 실링재(65,15)를 통과한 후 결합공(62,12)에 결합할 수도 있다.Alternatively, after the sealing materials 65 and 15 are first seated on the engaging projections 63 and 13 formed on the inner periphery of the coupling holes 62 and 12 of the above-described inlet 58 and outlet 8, the external refrigerant pipe 59 , 9) is inserted into the coupling holes 62, 12, after the sealing material separation prevention holes 66 and 16 of the external refrigerant pipes 59 and 9 pass the sealing materials 65 and 15, the coupling holes 62 and 12 ) can also be combined.

전술한 실링재 이탈방지구(66,16)에 끼워진 실링재(65,15)를 결합공(62,12)의 걸림턱(63,13)에 안착시킨 상태에서, 흡입구(58) 및 배출구(8)의 외주연에 형성된 나사부(58b,8b)에 이와 대응되는 나사공이 내주연에 형성된 체결너트(60,10)를 나사결합하여 체결한다.In a state in which the sealing materials 65 and 15 fitted into the above-described sealing material separation prevention ports 66 and 16 are seated on the engaging projections 63 and 13 of the coupling holes 62 and 12, the suction port 58 and the discharge port 8 A screw hole corresponding to the screw hole formed on the outer periphery of the threaded portion (58b, 8b) is fastened by screwing the fastening nut (60, 10) formed on the inner periphery.
