Description

Electric stewpan

Technical Field

The utility model relates to the technical field of cooking utensils, especially, relate to an electric stewpan.

Background

When the existing electric stewpan is used for cooking porridge or stewing some sticky and easily foamed food materials, the phenomenon of pot overflow is often caused. To avoid this problem, in the conventional electric stewpot, a temperature sensing probe is generally disposed on the bottom or the sidewall of the inner pot to detect the temperature in the inner pot in real time, and when the temperature rises to a preset value, a main control board in the electric stewpot controls the power of the heating element to be reduced, so that the food material in the inner pot is kept in a boiling state but does not overflow until the cooking is completed. Since the food in the inner pot is boiled to the end of cooking, the heating element in the electric stewpot is controlled to be in a low-power working state, so that a long time is required from the boiling of the food in the inner pot to the completion of final cooking, and the cooking efficiency is low.

In cooking appliances such as electric pressure cookers, electric cookers and the like, in order to avoid overflow or blocking of an air outlet by foam, an air pump or a fan and other devices for generating foam breaking air flow are arranged on a cover body, when a temperature sensing probe detects boiling in a pot, an air pump or a fan works to generate air flow, and foam generated by boiling is eliminated by utilizing low temperature and flow velocity impact of the air flow.

Although the anti-overflow device applied to the electric pressure cooker and the electric rice cooker can break bubbles by airflow without reducing the power of the internal heating element to reduce the generation of bubbles, the anti-overflow device cannot be applied to the electric stewpot. Particularly, in cooking appliances such as an electric stewpot, an electric pressure cooker and the like, the pot cover and the pot body are always connected, and the anti-overflow device can be electrically connected to the pot body conveniently through a wire. Unlike this, there is no connection between the upper cover and the pot body of the electric stewpot, and therefore, the upper cover of the electric stewpot is provided with an anti-overflow related structure, the electrical connection manner of which needs to be redesigned.
