Problems solved by technology
[0004] (1) The time of weight change detection is later than the control time of the valve, so after adjusting the opening and closing degree of the valve according to the weight change detection, the water in the water supply pipeline will still flow into the cooking chamber, and there is a large deviation in the control process;
[0005] (2) The weight change detection must be based on a fixed cooking menu to monitor the water supply process, and the cooking process has poor flexibility

The invention provides a cooking appliance, a flow rate control method, and a flow rate control device, wherein the cooking appliance includes: a cooking chamber for containing materials, and the cooking chamber is connected to a liquid inlet of the cooking appliance; a liquid inlet pipeline, Connected between the liquid source outside the cooking chamber and the liquid inlet; the flow meter is arranged in the liquid inlet pipeline and connected to the microprocessor for detecting the flow rate of the liquid in the liquid inlet pipeline, and the flow rate Feedback to the microprocessor; the electric control valve is set in the liquid inlet pipeline and connected to the microprocessor, and the electric control valve feeds back the opening and closing of the valve to the microprocessor according to the preset cycle; the microprocessor is connected to the flow rate The meter is used to record the relationship curve of flow velocity and time, so as to determine the flow value at any time according to the relationship curve and the degree of opening and closing at the corresponding moment. Through the technical solution of the invention, the automatic water supply process of the cooking appliance is precisely controlled, which is beneficial to improving the cooking effect.
Description
technical field [0001] The present invention relates to the technical field of cooking utensils, in particular, to a cooking utensil, a flow rate control method and a flow rate control device. Background technique [0002] In order to improve the user's cooking experience, more and more cooking appliances are equipped with an automatic water supply function, such as water supply during rice washing or cooking. [0003] In the related technology, the monitoring of the automatic water supply process is realized through the detection of the weight change of the inner pot, but there are at least many shortcomings in the detection of the weight change of the inner pot as follows: [0004] (1) The time of weight change detection is later than the control time of the valve, so after adjusting the opening and closing degree of the valve according to the weight change detection, the water in the water supply pipeline will still flow into the cooking chamber, and there is a large devi...
