Cooking appliance and anti-overflow control method thereof

Abstract

The invention discloses a cooking appliance and anti-overflow control method thereof. The cooking appliance comprises a pot body and a cover body. The cover body comprises an inner cover and a cover plate, wherein the inner cover is provided with at least one negative pressure hole, and the cover plate is disposed on the side of the inner cover facing a cooking chamber and a plurality of airflow through holes. The vacuum device is arranged corresponding to the inner cover, and is connected with at least one negative pressure hole, and the vacuum device vacuums the cooking chamber to form a negative pressure bubble burst area between the inner cover and the cover plate. When the cooking appliance enters the boiling stage, a control module is used for controlling the vacuum device to make the bubbles generated in the cooking chamber burst when contacting the negative pressure bubble burst area. According to the cooking appliance and anti-overflow control method thereof, when the cookingappliance enters the boiling stage, the control module controls the startup and shutdown of the vacuum device so that bubbles generated in the cooking chamber are burst when contacting a negative pressure bubble burst area, so that rapid, large-area bubble burst is realized, and the anti-overflow effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to an anti-overflow control method for cooking utensils and a cooking utensil. Background technique [0002] In the related art, cooking utensils such as electric rice cookers are prone to overflow when cooking food, which not only brings troubles for cleaning to the user, but also causes loss of food nutrition and affects the cooking effect. [0003] At present, some rice cookers use rotating turbine negative pressure foam breaking technology to prevent overflow, but there are problems such as low negative pressure value, poor foam breaking effect, short turbine life, etc. In fact, it cannot solve the overflow problem of rice cooker cooking well. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the above-mentioned technologies at least to a certain extent. Therefore, an object of the present invention...
