Abstract
PURPOSE: To obtain a vortex fan having the same blowing performance at a low cost in a district of 50Hz or 60Hz by adjusting part of a casing cover.
CONSTITUTION: As the depth 8 of the voltex chamber 12 becomes smaller in a casing cover 13 the maximum of the air output becomes lower. Now, the depth of the vortex chamber 12 in the casing cover 13 is indicated by a real line 8 for the 50Hz and the depth for the 60Hz is reduced as indicated by a one-dotted chain line. The casing cover 13 is manufactured from casting, die casting. The surface joined with a casing body 11 is made by cutting operation for the sake of precision. The casing cover of only one type designed for 50Hz is served for any casing covers and change of 50Hz to 60Hz is made sufficiently by increasing the cutting allowance in cutting operation. In this manner, the same blowing performance can be obtained in the districts of 50Hz and 60Hz by adjusting part of the casing cover 13.
