Cooking appliance, flow control method and flow control device

Abstract

The invention provides a cooking appliance, a flow control method and a flow control device, wherein the cooking appliance comprises a cooking cavity, a liquid inlet pipeline, an electromagnetic valve, a flow meter and a microprocessor, wherein the cooking cavity is used for keeping materials and the cooking cavity communicates with a liquid inlet of the cooking appliance; the liquid inlet pipeline is connected to a space between a liquid source outside the cooking cavity and the liquid inlet; the electromagnetic valve is arranged in the liquid inlet pipeline and is connected to the microprocessor, and a valve body of the the electromagnetic valve is turned on or turned off by virtue of a driving signal of the microprocessor; the flow meter is arranged in the liquid inlet pipeline and is connected to the microprocessor; the flow meter, when detecting out that liquid passes through the liquid inlet pipeline, can generate unit pulse signals, and the unit pulse signal is fed back to the microprocessor; and the microprocessor is connected to the flow meter and is used for determining a flow rate of the liquid in accordance with the number of the unit pulse signals. According to the technical scheme provided by the invention, an automatic water supply process of the cooking appliance is precisely controlled, so that a cooking effect is enhanced.

Description

technical field [0001] The present invention relates to the technical field of cooking utensils, in particular, to a cooking utensil, a flow control method and a flow 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 deviation in t...

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
