Novel degerming device

Abstract

The invention discloses a novel degerming device. The device comprises a box body and a box cover connected to the top of the box body in a buckled mode, an isolation heat dissipation plate is arranged in the box body in the front-back direction, the isolation heat dissipation plate divides the box body into a left cavity and a right cavity, and an ultraviolet lamp, a titanium dioxide net and a draught fan are arranged in the right cavity; a plurality of air holes are formed in the side wall, the bottom wall and the box cover of the right cavity respectively; and a circuit control board is arranged in the left cavity and connected to the ultraviolet lamp and the fan, a heat pipe is connected between the circuit control board and the isolation heat dissipation plate, the upper portion of the heat pipe is attached to the isolation heat dissipation plate, and the lower portion of the heat pipe is attached to the circuit control board. The temperature of the circuit control board is effectively reduced, and the circuit control board is protected against oxidation corrosion, so that the service life of the circuit control board is greatly prolonged, and important technical obstacles areremoved for wide application of the independent degerming device to refrigerators. According to the invention, a production mold of existing refrigerators does not need to be changed, and the designcost and high mold opening cost for designing a novel degerming refrigerator are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerator sterilization, in particular to a sterilization device that does not need to change the mold of the existing refrigerator. Background technique [0002] With the development and application of sterilization technology, more and more refrigerator products apply new sterilization technology. In the past, refrigerators used a single sterilization method, and the sterilization device passively contacted and sterilized the air in the refrigerator, so it was difficult to achieve the ideal sterilization effect. [0003] Refrigerators come in a variety of styles and structures. If the sterilization function is added to refrigerators already on the market, the electric control, cabinet structure, and refrigeration system of existing refrigerators will be changed, especially in the mold of the cabinet structure. huge. [0004] In experiments and actual use, the sterilization module will generate ultr...

AI Technical Summary

Problems solved by technology

[0005] Heat generation and contact with strong oxidizing substances will inevitably shorten the life of the circuit control board. This phenomenon has formed an obstacle to the design and manufacture of a universal refrigerator sterilization device that is independent of the main structure of the refrigerator and is suitable for various existing refrigerators. In addition to the main structure of the refrigerator, the general-purpose refrigerator sterilization device suitable for various existing refrigerators is difficult to popularize and apply due to its short lifespan. We can only redesign the refrigerator mold. Costs such as mold design costs to manufacture sterilizing refrigerators
