Infrared intelligent telemetering temperature control system

Abstract

The invention discloses an infrared intelligent telemetering temperature control system and belongs to the technical field of cooking utensils. The system is characterized in that a gas stove and an infrared temperature detector are split, the temperature in a pan is detected in an overlooking manner by the infrared temperature detector; temperature information sensed by an infrared temperature sensor is converted into an electrical signal, the electrical signal serves as sampling information for temperature detection of the pan to be input into a program controller for calculation, and a gas solenoid valve is controlled to adjust the heat of a combustor. The system has the advantages that the cooking process is intelligent, free of oil fume and healthy; the sensor is far away from a stove cooking region with relatively serious oil fume pollution, the interference of flame at the bottom of the pan on the detection accuracy is avoided, and the service life of equipment is greatly prolonged; a function of automatically turning off the heat during lifting of the pan is added; a function of preventing dry burn during stewing is added; the operating habit of a conventional gas stove is basically not changed.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, in particular to an infrared intelligent remote measurement temperature control system. Background technique [0002] At present, gas stoves are still mostly used in households. Due to technical factors, gas stoves have always been difficult to achieve automatic temperature measurement and control of pots with good reliability, and it is also difficult to achieve oil-free cooking. Some of the new gas stoves in China are only doing a lot of work on smoke exhaust. Some of the various pot temperature detection technologies that have applied for patents before actually do not have the stability in actual operation. The key reason is that they have not selected suitable sensors. , or the sensor cannot separate the flame temperature very well.

[0002] At present, gas stoves are still mostly used in households. Due to technical factors, gas stoves have always been difficult to achieve automatic temperature measurement and control of pots with good reliability, and it is also difficult to achieve oil-free cooking. Some of the new gas stoves in China are only doing a lot of work on smoke exhaust. Some of the various pot temperature detection technologies that have applied for patents before actually do not have the stability in actual operation. The key reason is that they have not selected suitable sensors. , or the sensor cannot separate the flame temperature very well. Even if there is an invention using infrared temperature measurement technology, the placement of the sensor is limited to the stove body, which is still not available due to the existence of the flame and cooking waste. Feasibility, generally, people no longer use gas burner stoves for boiling water and cooking. With the popularization of rice cookers, gas stoves are more used for soup and cooking, and cooks pay more attention to it. To reduce the fume and nutrition of cooking, it is necessary to constantly adjust the cooking temperature at any time. The high temperature and invisible factors of the pot make it difficult for the cook to control the scale. In practice, the oil temperature of the first oil will easily affect the oil quality. , and when the vegetables are put in, the temperature of the pot and oil will drop. At this time, according to the characteristics of Chinese cooking, a high fire is required. Only when there is more water in the pot, the temperature will not easily rise to the boiling point of the oil. For many dishes, the firepower is too small , the taste will be unpalatable. The current sensor technology detects the temperature change of the pot from the bottom of the pot. Due to the direct interference of the flame temperature, its stability is very poor, and it cannot achieve the ideal and practical intelligent temperature control purpose. It is not suitable for application. too realistic
