CASING OF WINDOW TYPE AIR CONDITIONER

摘要

PURPOSE: A method for producing a casing of a window typed air conditioner is provided to increase productivity by reducing the number of processes as integrally forming an additional inner insulating unit. CONSTITUTION: A casing(40) is produced by extruding and divided into an upper case and a lower case(41)(42). The upper and lower case form a hollow insulating chamber(51) by injecting gas inside when producing the cases by an extruding process and the injecting hole is produced in the state of sealing. Therefore, the method increases productivity as the casing does'n't need an additional insulating material.
