REFRIGERATOR HAVING VERTICAL COLD AIR DISTRIBUTION BLADE

摘要

PROBLEM TO BE SOLVED: To perform uniform distribution of cold air in a vertical direction as a vortex flow is prevented from occurring to the periphery of the outlet of a cold air discharge by a method wherein a number of plate-form blades are arranged in parallel to each other in a cold air duct and rotated in reciprocation along a horizontal axis. ;SOLUTION: A vertical distribution device 30 having a number of plate-form vertical distribution blades 51 is formed in a supply duct. A horizontal shaft 58 is arranged on the vertical distribution blades 51 and inserted in shaft holes 47 of flanges 45 arranged on both sides of a duct plate 9 to rotatably support each vertical distribution blade 51. Further, an interlocking member 41 is extended through a position separated away by a given distance from the horizontal shaft 58 and coupled to each vertical distribution blade 51. In this case, a work protrusion 42 formed on the upper end part of the interlocking member 41 is engaged with a cam group 67, and the interlocking member 41 is elevated through rotation of a cam 65. This constitution changes the discharge direction of cold air by changing the rotation angle of the vertical distribution blade 51.;COPYRIGHT: (C)1999,JPO
