PURPOSE: A hose connection structure is provided to reduce piping time by easily connecting a flexible hose and a pipe outlet and to firmly connect the flexible hose and the pipe outlet without using an adhesive. CONSTITUTION: A hose connection structure comprises a coupling nut (22), a compressing washer (28), and an adapter (38). The coupling nut comprises a hollow part, a protrusion, and a female screw part (26). The compressing washer is fitted in the end of a hose (16) passing through a through-hole and is a ring shape with an inclined outer surface. The adapter comprises a pipe-shaped body (41) and a flange (40). One end of the body is inserted in the end of the hose inserted in the compressing washer, and the other end thereof communicates with a pipe outlet (12) to communicate the hose and the pipe outlet. One side of the flange is extended outward from the outer surface of the body to support the end of the pipe outlet. |
