Grounding structure of microwave oven heater

Abstract

The invention discloses a grounding structure of a microwave oven heater, which comprises a heater 40 and a grounding wire 50 connected with the heater 40; one end of the heater 40 exposed out of an oven body of the microwave oven is pressed by a copper sleeve tube 41 to be fixed with a grounding wire terminal 42; one end of a lead wire 52 of the grounding wire 50 is provided with a grounding ring51 fixed with the oven body of the microwave oven, and the other end of the lead wire 52 of the grounding wire 50 is provided with an inserting terminal 53; and the inserting terminal 53 is connectedwith the grounding wire terminal 42 of the heater 40 in an inserting way. The grounding structure of the microwave oven heater has the advantages of simple and convenient assembly, good firmness andstrong toughness. Components such as the grounding wire connected with the heater and the like can not be damaged even though the heater is operated for ten thousand times so as to ensure that the wire body can not be broken and greatly improve the safety performance of the microwave oven. The grounding structure has great significance for production practice.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a grounding structure for a microwave oven heater. Background technique [0002] A microwave oven is a device that generates microwaves from an electric current and irradiates the microwaves to the surface of the object to be heated in the cavity to heat the object. As everyone knows, microwave oven is a kind of modern cooking stove that heats food with microwave. The microwave it uses is a kind of electromagnetic wave. The energy of this electromagnetic wave is not only much greater than that of ordinary radio waves, but also has special characteristics. When the microwave hits metal, it will reflect, and the metal has no way to absorb or conduct it; microwave can pass through insulation such as glass, ceramics, and plastics. Materials, but will not consume energy; and food containing water, not only can not pass through the microwave, but its energy will be absorbed. Bas...

AI Technical Summary

Problems solved by technology

The connection structure between the heater and the ground wire has been proved by the heater rotation life experiment. Generally, after the heater rotates for 1000 cycles, the fixed lead wire at the copper sleeve 41 will be broken. Obviously, when the user uses the microwave oven If the grounding wire fails due to the breakage of the lead wire during the process, it will seriously affect the safety of the microwave oven user and form a great safety hazard.
