The refrigerator is heated with a defrost and deodorizing heating wire, which has an inner and outer tube, and a heating wire is installed inside the inner tube. The two ends of the inner and outer tubes are respectively equipped with end sleeves, and an expansion cavity is provided in the end sleeves. The two ends of the inner tube are equipped with baffles, and the two ends of the heating wire are connected to the connecting block and the center of the end sleeve through the connecting wires. The surface of the outer tube is coated with a layer of deodorization catalyst coating, which can absorb the odor in the refrigerator at low temperature, and decompose the adsorbed odor and restore the catalyst to the initial state at the high temperature of heating and defrosting, so that the original single-function defrosting becomes a simultaneous deodorization function. The end sleeve of this integrated design not only fixes and closes the inner and outer tubes, but also fixes and seals the heating wire lead; It not only completes the installation, fixing and sealing assembly at the same time, but also facilitates intensive production, reduces production costs, and has the functions of impact resistance and explosion prevention.
