SOUND MUFFLING DEVICE FOR AIR CONDITIONER

摘要

PURPOSE: To prevent any frictional sound from being generated without setting a large clearance between a suction grill and a front frame, without damaging its design characteristic and without allowing any dust to enter an air conditioner even in the case that a suction grill shows an inward warp by a forming condition. CONSTITUTION: A lateral rib 4 for reinforcing a strength of a suction grill 1 is provided with a protrusion 3 having either a spherical or an acute extremity shape. The suction grill 1 and a front frame 2 are constructed such that they are not surface contacted or line contacted, but point contacted or they are constructed such that the lateral rib 4 is provided with the protrusion 3 made of soft material quality and then the front frame 2 is contacted with the protrusion 3.
