Cookware heating controlling method and heating-state examination method

Abstract

The invention relates to a cookware heating controlling method and a heating-state examination method. The heating controlling method comprises the following steps: controlling the gas flow conveyed to a heating apparatus to be a first gas flow; monitoring the heating gradient when the cookware is heated, determining that the interior in the cookware is at a boiling state when the heating gradient absolute value is less than a first gradient value in a first time frame, controlling to reduce the supplied gas flow to a second gas flow, and continuing to heat; and determining the cookware is at an empty burning state when the heating gradient absolute value is larger than a second gradient value in the first time frame, and stopping conveying gas to the heating apparatus.

Description

technical field [0001] The invention is related to the control of gas appliances, in particular to a heating control method and a heating state detection method of a pot. Background technique [0002] By the way, gas cookers are usually the main appliances used for cooking a large amount of ingredients. Take gas rice cookers as an example. The heat energy is greater than the heat energy generated by using electricity, so that the rice and water in the pot can be fully mixed, the cooked rice tastes better, and the cooking time is short. [0003] The heating device of the known gas rice cooker utilizes a thermal expansion switch to sense the temperature of the pot. When the temperature of the pot rises to the default temperature (the current gas rice cooker is mostly set at 135° C.), the thermal expansion switch is actuated and blocked. The gas supply is turned off while the heating is stopped. During the whole cooking process, it is continuously heated with high fire, so th...

AI Technical Summary

Problems solved by technology

During the whole cooking process, it is continuously heated with high fire, so the rice at the bottom of the pot is easy to burn. Therefore, it is necessary to spread a napkin on the bottom of the pot so that the rice will not directly touch the bottom of the pot to avoid burning; Or, regardless of the amount of ingredients in the pot, under the same heating conditions, even experienced users cannot ensure that the quality of rice cooked every time is stable

In addition, the longer the mechanical expansion switch is used, the higher the probability of failure; if the food in the pot is not cooked, if it is serious, the food will be burnt, and even worse, there may be a fire hazard

[0004] In addition, when the known gas pot is used for cooking soup, continuous high-heat heating will only damage the appearance of the soil ingredients, and the essence of the ingredients cannot be boiled into the soup, and the cooking time cannot be controlled, which is quite inconvenient to use.

Therefore, the design of the known gas cooker is still not perfect, and there is room for improvement
