Background

The electromagnetic oven has the problem of boiling and overflowing during the use process of cooking soup and porridge, so that the product quality and the user experience are greatly reduced.

The general method is a passive anti-overflow structure design, for example, a water guiding rib with a flow channel function is arranged around a heat dissipation hole of the induction cooker, and a drain hole is arranged at the end of the water guiding rib, when the overflow volume of the induction cooker is large, water passes through the water guiding rib and is quickly drained to the outside of the induction cooker through the drain hole. However, the passive overflow-preventing structural design can not realize overflow early warning and intelligent control, and the potential risk of overflow-preventing failure exists when the water quantity is too large or the heating is too fast.

In addition, many solutions adopt contact-type anti-overflow electrodes to realize anti-overflow identification, and these anti-overflow electrodes all need to be assembled on the pot cover of electromagnetism stove pan, and it is inconvenient to wash and assemble, and user experience is relatively poor. And part of the electromagnetic oven cookware has no exhaust holes, so that an anti-overflow electrode cannot be used, and the universality is poor. In addition, because the power supply is lack when the pot cover is installed, so the pot cover is usually powered by batteries, the service life is greatly limited, and the batteries need to be replaced frequently.
