It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

Furthermore, to facilitate a better understanding of this application, certain specific details are described in detail below in the detailed description of this application. Those skilled in the art will be able to fully understand this application without these details.

[0016] See also Figure 1 and Figure 2 As shown, a refrigerator de-icing device based on heating by a heating resistance wire includes a polytetrafluoroethylene shell 1 and a rechargeable lithium battery 2, a ceramic heat insulator 3, a heating resistance wire 4 and a heating metal plate 5 arranged in sequence from top to bottom. The rechargeable lithium battery 2 is installed in the polytetrafluoroethylene shell 1, the heating resistance wire 4 is electrically connected to the rechargeable lithium battery 2, and the heating metal plate 5 is installed at the bottom of the polytetrafluoroethylene shell 1 with a gap between the heating resistance wire 4 and the heating metal plate 5. The ceramic heat insulator 3 is provided with a through groove 6 for the heating resistance wire 4 to pass through.

[0017] The ceramic insulation body 3 is fixedly installed in the polytetrafluoroethylene housing 1 .

[0018] A rubber handle 7 is provided on the top of the polytetrafluoroethylene shell 1 .

[0019] The top of the polytetrafluoroethylene shell 1 is provided with a switch 8, which is used to control

[0020] The heating resistor wire 4 is connected and disconnected with the rechargeable lithium battery 2 .

[0021] The polytetrafluoroethylene housing 1 is provided with a charging port 9 for charging the rechargeable lithium battery 2 .

[0022] This utility model utilizes a heating resistor wire to generate heat, which in turn heats a heating plate. The heating plate is anodized with A6061. The heating plate contacts ice, thereby defrosting the refrigerator. A rechargeable lithium battery provides power to the device, ensuring the heating plate remains cool and prevents damage. Rubber handles provide insulation to prevent burns. A ceramic insulator separates the rechargeable battery, the heating resistor wire, and the heating plate. The ceramic insulator has slots for the heating resistor wire. The device's housing is constructed of polytetrafluoroethylene.

[0023] like Figure 3 As shown, sealing rings 10 are used on both sides between the heating metal plate and the polytetrafluoroethylene shell to prevent water from entering the device during deicing operations and causing damage to the circuit.

[0024] The innovative structure of the resistance wire and heating metal plate in this device allows the heating metal plate to effectively transfer the heat from the resistance wire to melt the ice. Its excellent heat transfer properties also prevent the resistance wire from overheating, extending its lifespan. Furthermore, because the A6061 aluminum plate is anodized, the poor electrical conductivity of aluminum oxide prevents leakage issues that can occur with ordinary metal plates.

[0025] This utility model features a novel structural design that separates the rechargeable lithium battery from the heating resistor, minimizing heat transfer from the resistor to the outside through the heating plate. The resistor is embedded within a groove in the ceramic insulation, increasing the effective heating length and maximizing space. Sealing rings are also used inside and outside the heating plate to secure it securely and prevent water from entering the device and damaging the circuitry.

[0026] This innovative structure effectively utilizes the device's internal space, resulting in a simple, compact, reliable structure that is easy to maintain. Its small size allows for a wide range of applications. The use of a rechargeable lithium battery eliminates the need for plugging in, making de-icing operations more convenient.
