AUTOMATIC VENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To easily and surely attach an air guide duct in an automatic vending machine with no inner box and with an exposed synthetic resin heat insulation material stuck to the inner wall surface of an outer box. SOLUTION: In the duct 15 having a front part 15a and both-sides surface parts 15b and formed of a steel plate into an approximately U-shaped cross section, plate-shaped projecting pieces 16 are attached to the rear edges in the upper parts of the both-sides surface parts 15b. The plate-shaped projecting piece has an edge part, its one side clamping the edge part is formed into an oblique side inclined downward from the base part to the edge part, and the other side is formed into a horizontal side 16b. The duct 15 is so formed that the synthetic resin heat insulating material 3 stuck to the inner wall surface of the outer box 1 is pierced with the plate-shaped projecting piece 16 and an approximately L-shaped fitting piece 17 formed in the lower part of the duct 15 is attached to a metal cover plate 18 in the bottom part by a screw 8. The upper part of the duct 15 is pushed by a rack 4 disposed after attaching the duct 15 to completely prevent the pullout of the plate-shaped projection 16. COPYRIGHT: (C)2003,JPO
