Title:
FAN GUARD AND AIR CONDITIONER INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2019056531
Kind Code:
A
Abstract:
To secure strength of a fan guard and to improve designability in a fan guard 3 formed by a plurality of main bars 31 arrayed in parallel and a plurality of auxiliary bars 32 orthogonal to the adjacent main bars.SOLUTION: Auxiliary bars are arrayed in the left-to-right direction along a main bar 31 by providing a first interval Wb and a second interval Wc whose width is three times wider than the first interval alternately. The auxiliary bars adjacent to each other by sandwiching the main bar are arrayed so that the first interval Wb and the second interval Wc appear alternately along the main bar 31. Thereby, as one side of the main bar is supported by two pieces of auxiliary bars of the first interval, even when a second interval of the auxiliary bar is located on the other side, deflection is suppressed by being pulled by two pieces of auxiliary bars, and strength increases.SELECTED DRAWING: Figure 2
