AI Technical Summary

Technical Problem

In existing freezers, the heating wires are in direct contact with the evaporator, resulting in uneven heat distribution, low defrosting efficiency, heat transfer to the storage space affecting the cooling effect, and the drain hole is prone to ice blockage, leading to water leakage.

Method used

The evaporator heater is placed at the bottom of the evaporator compartment and laid along the extension direction of the base plate. It adopts a serpentine design, combined with inclined and concave structures, and is fixed with thermally conductive tape to limit the linear power density and surface density. A fan heater is installed to prevent the fan from frosting.

Benefits of technology

It achieves uniform defrosting of the evaporator, avoids local overheating and ice blockage, improves the operational stability and energy efficiency of the freezer, and provides an efficient and safe refrigeration environment.

Abstract

The utility model discloses a refrigerator, including evaporator storehouse and evaporator heater, and evaporator storehouse includes cabin and bottom plate, evaporator heater lays in the side of bottom plate far from evaporator, and evaporator heater extends along the extension direction of bottom plate, and evaporator heater is used to send heat to defrost evaporator. This refrigerator sets up evaporator heater at the bottom of evaporator storehouse, and the installation mode of laying makes the heat evenly transmit to evaporator through bottom plate, avoids the problem of local uneven heating caused by the direct contact of heating wire and evaporator in traditional design, thereby significantly improves the uniformity and efficiency of defrosting.
