Electric cooking utensil and anti-overflow device and anti-overflow control method therefor

Abstract

The invention discloses an anti-overflow device for an electric cooking utensil. The anti-overflow device comprises a distance detection module and a controller; the distance detection module is disposed in an upper over of the electric cooking utensil and is used for detecting a distance between the lower surface of the upper cover and a level of food materials cooked in an inner pot of the electric cooking utensil; the controller is connected with the distance detection module and is used for controlling the electric cooking utensil to stop heating or reduce power of heating so as to prevent overflowing of the electric cooking utensil, when the distance between the lower surface of the upper cover and the level of food materials cooked in the inner pot is less than or equal to a preset distance. The anti-overflow device is capable of accurately detection an event wherein thin gruel is about to overflow from the electric cooking utensil during cooking, thereby avoiding causing cleaning and maintenance problems. The invention further discloses the electric cooking utensil and an anti-overflow control method for the electric cooking utensil.

Description

technical field [0001] The invention relates to the technical field of living appliances, in particular to an anti-overflow device for an electric cooking appliance, a method for controlling the anti-overflow of the electric cooking appliance, and an electric cooking appliance with the anti-overflow device. Background technique [0002] At present, in the process of using electric cooking appliances such as electric rice cookers to cook rice, the rice soup is heated, which will inevitably produce a large amount of foam. Security risks. [0003] In related technologies, although some technologies for preventing rice soup from overflowing have been proposed, either the precision is poor, the detection is inaccurate, and overflow occurs when the rice cooker is cooking; or the cost is expensive, and it can only be detected after the rice cooker has overflowed. , causing trouble in cleaning and maintenance. Therefore, the technology of preventing the rice soup from overflowing ...
