Refrigerator box body inner container structure

Abstract

The invention discloses a refrigerator box body inner container structure. Two square holes are formed in a refrigerator inner container; supporting frames are arranged in the square holes and are fixed through bonding; fin evaporator pipelines are clamped in two semicircular arcs on locking end faces on the supporting frames; heating wires are mounted on fin evaporators and are fixed in circular-arc clamping grooves formed in surfaces of fins through steel wire buckles; bottom heating wires of the evaporators are guided into the bottom of a water receiving groove and are fixed through aluminum foil adhesive tapes; the water receiving groove is formed in the bottom of the refrigerator inner container; and a water discharging opening is formed in the bottom of the water receiving groove. The refrigerator box body inner container structure disclosed by the invention has the following benefits that the whole body of the refrigerator inner container is molded by injection, rapid installation of the fin evaporators of a refrigerator is realized and the installation cost is reduced, so that the production efficiency is improved.

Description

technical field [0001] The invention relates to an inner tank structure, which is especially suitable for use in air-cooled refrigerator inner tanks, refrigerators, and freezer refrigerators. Background technique [0002] For the finned evaporator installed in the inner liner of the existing air-cooled refrigerator, the finned evaporator is usually fixed to the inner liner on both sides of the finned evaporator with an electric screwdriver. At present, most refrigerator factories are using it; 1. The inner tank of the refrigerator is injection-molded and does not need to open holes on the top, and the bottom of the inner tank is equipped with a drain; 2. The finned evaporator has aluminum tubes, fins, and aluminum end plates on both sides. , water accumulation plate, heating wire, sensor, etc.; the production process is aluminum tube, fin blanking, and expansion tube to ensure the interference fit between the fin and the aluminum tube, the fins are tight and there is no loos...
