Embodiment Construction

[0008] In order to solve the problems of hard bottom, sticky bottom, or even burnt bottom and waste of electric energy when cooking rice in the electric rice cooker in the prior art, the specific measures taken in this plan are: install a vibration sensor on the electric rice cooker, and connect the vibration sensor to the sound pattern The recognition circuit, the voiceprint recognition circuit is connected to the control circuit, and the control circuit is connected to a heating plate or a heating coil.

[0009] Friends who have cooked rice carefully will find that the inner pot of the rice cooker will emit different vibrations at different stages during the cooking process. These vibrations are the different sounds we hear. It can accurately reflect the instant real situation of the inner pot of the electric rice cooker. For example, there is no vibration at the beginning of heating, and as the temperature rises, bubbles and the sound of bubble bursting are slowly produced ...

Abstract

The invention relates to the technical field of electric cookers in household appliances, in particular to a voiceprint recognition controlled energy-saving electric cooker which aims at solving the structural problem that hard bottoms, sticky bottoms, electricity waste and the like often occur when the electric cookers are used for cooking in the prior art. The technical scheme includes that a vibration sensor is mounted on an electric cooker and connected with a voiceprint recognition circuit which is connected with a control circuit which is connected with a heating disc or a heating coil, and the like. A conventional control mode taking temperature changes of an inner pot as a control basis is changed into a control mode taking voice changes namely voiceprint changes inside the inner pot as a control basis, so that the problem that control lags behind actual temperature changes of the inner pot due to designability in the prior art of electric cookers. Voiceprints can reflect large amount of information, so that the control mode is more accurate and closer to actuality while electricity is greatly saved.

Description

technical field [0001] The proposal relates to a technical field of electric rice cookers among household appliances. Background technique [0002] In the electric rice cooker of prior art, no matter adopt the common electric rice cooker of mechanical temperature limiter or more high-grade, adopt the intelligence of thermistor temperature limiter to be rice cooker. They all have one thing in common, that is, the temperature change in the inner pot is used as the control basis of the control circuit. Technically, this type of rice cooker has obvious defects, that is, the temperature measuring point is not a heating zone, and the temperature at this point obviously lags behind the temperature of the heating zone, which cannot reflect the real situation of the inner pot. During the cooking process, the water in the inner pot is heated to boil. After boiling for a period of time, part of the water in the rice cooker is absorbed by the rice, and the other part is turned into st...
