Description

Household automatic anti-overflow electric cooker with good cleanness

Technical Field

The invention relates to the technical field of intelligent home furnishing, in particular to a household automatic anti-overflow electric cooker with good cleanness.

Background

Electric rice cookers, also known as electric cookers and electric rice cookers. The electric cooker converts electric energy into heat energy, has various operation functions of steaming, boiling, stewing and the like on food, and is convenient to use, safe and reliable. The common electric cooker is mainly composed of a heating disc, a heat preservation switch, a lever switch, a current limiting resistor, an indicator light and the like, and rice and clean water in an inner container are heated mainly through the heating disc to cook.

The reason why the electric cooker often has the phenomenon of liquid overflow in the process of continuously cooking rice is that in the heating process, rice cooking water boils and evaporates sharply after reaching a boiling point, a plurality of bubbles with different sizes are generated while increasing the atmospheric pressure, the inner container of the electric cooker is in a relatively sealed environment, the bubbles break to generate liquid residues after completely growing, water in the electric cooker can continuously grow and break the bubbles under the action of hot pressure, the growth time speed is generally higher than the breaking speed, the water level of the bubbles is gradually increased until the bubbles collide with the bottom of the cooker cover, the pressure cooker cover generated by the broken bubbles can enable liquid residues to be generated at the gap between the cooker cover and the cooker body, and particularly porridge liquid is easily attached to the cooker cover and the cooker body during porridge cooking.
