Description

a gas stove

technical field

The invention relates to the technical field of stoves, in particular to a gas stove.

Background technique

A gas cooker is a gas burner that directly heats cooking utensils with fire. After the stove is ignited successfully, the flame heats the bottom of the pot, and the heat is transferred to the food in the pot through the pot, thereby heating the raw food and the cooked food. Most gas stoves on the market need to manually adjust the firepower. If you want to control the temperature when cooking, it depends on your personal experience. If you forget to turn off the fire due to urgent matters or omissions, the temperature will be too high, which will easily cause the pot to burn dry, and even cause major safety accidents.

In order to avoid the phenomenon of dry burning, dry burning pots have appeared, but common anti-dry burning stoves only have the function of preventing dry burning. Anti-dry function introduction: When cooking, when the temperature in the pot is higher than the dry temperature (dry pot state), the temperature sensing probe will send a signal to the controller, and the controller will control the solenoid valve to cut off the air source, so that the stove will be turned off and the temperature will be reduced. Pot temperature, to prevent dry burning. That is to say, only when the temperature in the pot is very high, the anti-boil-dry function will be activated. Usually, when the anti-boil-dry function is activated, the food in the pot has already been burnt. As we all know, burnt food has a high content of carcinogens, which is harmful to human health.

In addition, with the improvement of living standards, people pay more and more attention to the requirements of healthy cooking. For the four common cooking modes of stir-frying, low-temperature frying, high-temperature frying and steaming, the temperature in the pot needs to be controlled within different ranges. If the temperature is too high, it will not only fail to meet the cooking requirements, but will also produce carcinogens, which are harmful Healthy body.

Contents of the invention

In order to solve the above-mentioned technical problems in traditional cooking that the cooking temperature is difficult to control and carcinogens are easily produced, the invention discloses a gas stove.
