Smart kitchen system

This case is a kitchen system, especially a smart kitchen system.

All kinds of kitchen utensils in the kitchen, such as range hoods, gas stoves, pots, are independent of each other. When the chef uses the heat to fry, the fumes are everywhere. At this time, the chef has to manually start and adjust the exhaust of the range hood to the strongest. However, when the cooking is nearing completion, it is necessary to manually adjust the amount of exhaust of the range hood to a minimum. When the food is finished, the switch of the range hood should be manually cut off. Moreover, the range hood has been used for a long time, and the oil that is extracted is not easy to clean.

Also, when cooking in a pot, the chef needs to check to see if the fire is too big or too small, or if the boiler has no air burning, etc. If you forget the time and forget to check it, it may cause It is also common to hear that a fire is caused by a boiler burning. When the chef is frying, there is a term called "smoke point". The temperature of the different oil smoke points is different. When the pot reaches this temperature, the oil can be poured into the pot to get the best results. But when the average person is frying food, how do you know the temperature of the pot?
