AI Technical Summary

Technical Problem

Existing microwave oven interlock switches are easily activated when the door is open, posing a safety hazard, especially the risk of microwave leakage if children accidentally operate them.

Method used

By utilizing the directional conversion of elastic potential energy of elastic components, an interlocking switch with a self-locking function is designed. Through the cooperation of a cam and a micro switch, the micro switch is prevented from being accidentally triggered when the door is not closed.

Benefits of technology

The safety of the interlock switch is significantly enhanced, preventing the micro switch from being accidentally activated when the door is not closed, thus avoiding accidental start-up of the microwave oven and improving the overall safety of the microwave oven.

Abstract

The utility model relates to domestic appliance technical field discloses a kind of interlocking switch and cooking equipment, interlocking switch includes interlocking assembly, and interlocking assembly includes support, microswitch, cam and elastic member;Cam is rotatably arranged on support, and cam is equipped with lock hook part and arc touch part;When door body is closed, door hook promotes cam to rotate from initial position to critical position, and lock hook part forms lock with door hook, and arc touch part triggers microswitch;When door body is not closed and external force forces cam to cross critical position to reach self-locking position, arc touch part removes the triggering of microswitch, and elastic member makes cam keep self-locking position.The above-mentioned interlocking switch, through the directionality conversion of the elastic potential energy of elastic member, realizes the self-locking function of interlocking switch, can effectively prevent microswitch from being accidentally triggered when door body is not closed, and enhances the security of interlocking switch.
