AI Technical Summary

Technical Problem

Existing cooking appliances such as electric ceramic stoves are prone to misjudgment when there is no cookware detection, leading to safety hazards. In particular, when the bottom corners of the cookware are too rounded, the position is off-center, or the material is transparent, the infrared detection device is prone to false alarms.

Method used

The signal and reflection components are located on both sides of the heating zone. When the pot is placed, it blocks the light signal transmission, and when it is not placed, the light signal is connected. The light signal path is optimized by the mirror panel and the light guide to ensure detection accuracy.

Benefits of technology

It improves the reliability of cookware-free detection, reduces the possibility of misjudgment, reduces safety hazards, simplifies assembly procedures, and reduces costs.

Abstract

This application provides a cooking appliance, relating to the field of household appliance technology. The cooking appliance includes a control panel and a detection device. The control panel has a supporting surface for placing a pot, and the supporting surface has a heating zone. The detection device includes a signal component and a reflective component, located on opposite sides of the heating zone. The signal component includes a transmitting unit and a receiving unit. Along the thickness direction of the control panel, at least a portion of the transmitting unit, receiving unit, and reflective component extends beyond the supporting surface. The transmitting unit emits a light signal to the reflective component, and the reflective component reflects the light signal back to the receiving unit. When a pot is placed on the control panel, the pot is positioned between the signal component and the reflective component, blocking the light signal between them. When no pot is placed on the control panel, the light signal between the signal component and the reflective component is continuous. This cooking appliance can solve the safety hazard caused by false detection when no pot is present.
