Cooking utensil and method for automatically identifying rice types and then cooking rice by adopting utensil

Abstract

The invention discloses a cooking utensil which is characterized in that a weight sensor is arranged in a shell below an inner container, a pot cover is provided with a telescopic rod extending towards the inner container, an insulation detection disc is fixed to the end of the telescopic rod, and two conductive contacts are arranged on the insulation detection disc. The cooking method for automatically identifying the rice types by adopting the utensil comprises the following steps of: measuring the weight of the inner container when the inner container is vacant and the length of the insulation detection disc at the end part of the telescopic support rod when touching the bottom; measuring the weight of the inner container and the length of the telescopic supporting rod when the inner container is contacted with the surfaces of the rice grains after the inner container is filled with dry rice grains and water just submerges the rice grains, calculating the density of the rice by combining the sectional area of the inner container and the density of the water according to the mass and height difference before and after rice is added and water is injected and comparing the densitywith a database to obtain rice types, and injecting a proper amount of water. The cooking utensil has the advantages that the reliability and the accuracy are higher in a mode of identifying rice grains by utilizing the density, and the water adding amount is accurately and timely controlled in a mode of forming a closed loop by utilizing the contact conduction of water injection and the two conductive contacts.

Description

technical field [0001] The invention relates to a cooking utensil and a method for cooking rice by using the utensil to automatically identify rice types. Background technique [0002] Most of the existing electric cooker technologies allow the user to identify the type of rice and then add water according to the scale on the inner pot, so as to realize water allocation and then cook more fragrant and sweet rice. With the improvement of living standards, people are less and less exposed to crops, and even farmers who are exposed to crops are also difficult to accurately classify so many types of rice sold in the market as long and short grain rice. In this way, it is easy to produce the problem that the taste of the cooked rice is not good because of choosing the wrong kind of rice, and then reduce the satisfaction with the use of the product. [0003] Chinese Patent Document No. CN204181433U discloses a fully automatic rice cooker based on a built-in camera in the pot cove...
