Cooking appliance, flow rate control method and flow rate control device

Abstract

The invention provides a cooking appliance, a flow rate control method and a flow rate control device. The cooking appliance comprises a cooking chamber, a liquid inlet pipeline, a flow meter, an electric control valve and a microprocessor, wherein the cooking chamber is used for holding materials, and the cooking chamber is communicated to a liquid inlet of the electric cooking appliance; the liquid inlet pipeline is connected between a 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, the flow meter is used for detecting the flow rate of a liquid in the liquid inlet pipeline and feeding the flow rate back to the microprocessor; the electric control valve is arranged in the liquid inlet pipeline and connected to the microprocessor, and the electric control valve feeds the valve opening and closing degree back to the microprocessor according to a preset period; and the microprocessor is connected to the flow meter and used for recording a relation curve of the flow rate and the time so as to determine a flow value at any moment according to the relation curve and the opening and closing degree at the corresponding moment. According to the technical scheme of the invention, accurate control is performed on the automatic water supply process of the cooking appliance, therebybeing conducive 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...

AI Technical Summary

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
