Abstract
Method for producing a galvanized steel drain pan of rectangular or square configuration for use in refrigerators, freezers, and air conditioners to collect condensate water, the method includes the steps of: cutting a blank galvanized steel plate to the desired size; folding sides portions of the blank to a degree of 60 to 90 to form side portions of the drain pan; corrugating the corners formed by the side portions; and installing a drain fitting along with a pipe to drain the condensate water from the drain pan. Also disclosed is the drain pan made by the method.
Claims16
A method of producing a drain pan for use in refrigerators, freezers and air conditioners comprising the steps of:
- cutting a blank galvanized steel plate to a rectangular or square configuration, said blank having a size slightly larger than the desired size of the drain pan, said blank having four side edges and four corners;
- folding said side edges 180° to form a rim on said side edges;
- folding side portions of the blank upward at a degree of about 60 to 90 to form the side portions of the drain pan;
- notching said four corners of the blank and pressing them into corrugated configurations;
- punching a hole in one of the side portions of the blank to accommodate a drain fitting therein;
- and
- installing said drain fitting in said hole to complete the production of said drain pan.
A method of producing a drain pan for use in refrigerators, freezers and air conditioners for collecting condensates comprising the steps of:
- providing a blank galvanized steel plate having a thickness of from about 1 mm to about 3 mm;
- cutting said blank into a generally rectangular or square configuration, defined by four side edges and four corners and having a width of from about 12″ to about 36″ and a length of from about 12″ to 36″;
- folding about a 0.5″ to 1.0″ portion of side edges 180° towards the inside of said blank to form a rim thereon;
- folding back side edges parallel to said rim and spaced about 1″ to 5″ therefrom at an angle of 60° to 90°, to form side portions of the drain pan;
- notching said four corners of the blank and pressing them into corrugated configurations;
- punching a hole in one of the side portions to accommodate a drain fitting therein;
- and
- installing said drain fitting in said hole to complete the production of said drain pan.
A drain pan of galvanized steel having a thickness of about 1 mm to 3 mm for use in refrigerators, freezers and air conditioners to collect condensate water therein, said drain pan having a rectangular or square configuration comprising:
- a bottom wall having a size of about 12″ to 30″;
- side walls having a height of about 1″ to 5″ enclosing an angle of 60° to 90° with said bottom wall, said side walls terminating in rims;
- corrugated corners connecting said side walls;
- and
- a drain fitting positioned into one of said side walls to receive a tube to drain condensate water away from said drain pan, wherein said bottom wall, side walls and corrugated corners are integral with each other having no seams therebetween.
