ROLLER GUIDE THERMAL CONDUCTION STRUCTURE OF MULTIPURPOSE MICROWAVE OVEN

摘要

The present invention relates to a roller guide heat conduction attenuation structure of a multi-function microwave oven. In the related art, the internal temperature of the cooking chamber is increased by high frequency or heat of a heater, and the heat is transmitted to the roller guide 30 installed at the lower part of the tray. This has caused damage to and failure of parts due to overheating.;Therefore, in order to solve this problem, the present invention constitutes a disk-shaped multifunctional microwave roller guide in which a plurality of rollers 301 are laid out on the outer circumferential surface and a hub 40 is installed at the center of the bottom surface of the roller guide. When the heat applied to the roller guide 300 is transferred to the hub 40 by forming a plurality of heat attenuation holes 311 around the part 40 of the hub 40, the hub 40 is installed. It is extinguished through the heat attenuation hole 311 formed in the periphery of the part and only a small amount of heat is transferred to the hub. Thus, without using a separate heat-dissipating part as in the conventional shaft of the tray motor fitted to the hub, Since it can effectively block the heat transferred to the tray motor, it can greatly contribute to the cost reduction effect and the improvement of product safety and reliability by the functional improvement.
