Embodiment Construction
[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0036] In order to prevent the overflow of the pot, most of the current cookers are equipped with anti-overflow detection electrodes and reference electrodes on the pan, and judge whether it overflows according to the resistance between the anti-overflow detection electrodes and the reference electrode. However, when cooking, due to the difference...

The invention provides a cooker. The cooker comprises a first electrode (11), a second electrode (12), a resistance detection device (13), a capacitance detection device (14) and an overflow prevention detection device (15); the first electrode (11) and the second electrode (12) are spaced at the top of a cavity, used for containing foodstuff, of the cooker; the resistance detection device (13) isused for detecting the resistance value between the first electrode (11) and the second electrode (12); the capacitance detection value (14) is used for detecting the capacitance value between the first electrode (11) and the second electrode (12); the overflow prevention detection device (15) is used for judging whether an overflow signal is generated or not according to the resistance value andthe capacitance value. By means of the cooker, the accuracy of overflow detection can be improved.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a cooker. Background technique [0002] Current cookers, such as induction cookers, generally have the functions of boiling water, cooking porridge, and soup. However, when cooking porridge or soup, the problem of overflowing the pot often occurs, which not only causes waste of food resources, but also brings many problems to users. inconvenient. [0003] Some cookers with anti-overflow function have thus appeared on the market. When these cookers realize the anti-overflow function, most of them are provided with anti-overflow detection electrodes and reference electrodes on the pot. The anti-overflow detection principle of the cooker is: when cooking porridge or soup, if there is no overflow, the resistance between the anti-overflow detection electrode and the reference electrode is very large; The anti-overflow detection electrode and the reference electrode, the...
