Intelligent circuit of kitchen appliance and method for identifying boiling temperature therefrom

Abstract

The invention discloses an intelligent circuit for automatically identifying the boiling temperature of water at the altitude where a kitchen appliance locates and a method for identifying the boiling temperature. The intelligent circuit includes a power source module, a single chip control module, a heating relay drive module, and an LED (light-emitting diode) lamp drive module, wherein it further includes a key module, a NTC (negative temperature coefficient) temperature detecting module and a power failure memory. The kitchen appliance adopting the intelligent circuit is able to exactly detect the boiling temperature of water at the zone where the kitchen appliance locates and automatically store the boiling temperature in an electrical storage regardless of any altitude; thus when the kitchen appliance with the intelligent circuit is used every time in future, the circuit can immediately close a heating device of the kitchen appliance when the temperature of the food cooked in the kitchen appliance reaches the boiling temperature. Therefore, the intelligent circuit can prevent food cooked in the kitchen appliance from overflowing for excessive heating.

Description

technical field [0001] The invention relates to an intelligent kitchen appliance and a circuit control method, in particular to an intelligent circuit and method capable of automatically identifying the boiling point temperature of water in the altitude area where the kitchen appliance is used. Background technique [0002] The control technology of the intelligent kitchen appliances in the prior art is mainly designed for inland areas, and the judgment of water boiling in the intelligent control is designed according to the normal altitude. And when this product is used in high-altitude areas, the boiling point of water will be lowered due to the low pressure in high-altitude areas, which will easily cause people to misjudge the boiling point of water. When using the kitchen electric product in the above-mentioned area, the boiling point monitoring and protection must be carried out during each working process, but the ingredients cooked by the kitchen electric product are ...

Problems solved by technology

And when this product is used in high-altitude areas, the boiling point of water will be lowered due to the low pressure in high-altitude areas, which will easily cause people to misjudge the boiling point of water.

When using the kitchen electric product in the above-mentioned area, the boiling point monitoring and protection must be carried out during each working process, but the ingredients cooked by the kitchen electric product are different every time it works, so it is easy to The boiling point is inaccurately judged by the interference of the ingredients heated in the appliance; in addition, in order to accurately judge the boiling point of water, it is usually necessary to continue heating the kitchen appliance for a period of time after the ingredients boil, because it is difficult to continue heating for a period of time control, so this method can easily lead to the overflow of cooked ingredients
