Infrared temperature measuring device and gas stove using infrared temperature measuring device

Abstract

The invention relates to an infrared temperature measuring device and a gas stove using the infrared temperature measuring device. The infrared temperature measuring device comprises an infrared temperature measuring sensor for measuring temperature, and is characterized by also comprising a shell, the infrared temperature measuring sensor is installed in the shell, the surface of the shell is provided with a transmission hole, an antifouling sheet capable of transmitting infrared light is arranged in the transmission hole, a detection channel communicating with the transmission hole is formedin the shell, and the infrared temperature measuring sensor is arranged in the detection channel; the detection channel is straight and forms an included angle alpha with a horizontal plane, and alpha is more than 18 degrees and less than 23 degrees; and a collimating mirror which is positioned in front of the infrared temperature measuring sensor and is used for increasing the measuring distanceof the infrared temperature measuring sensor is also arranged in the detection channel. Compared with the prior art, a hole does not need to be formed in an inner ring of a combustor, most flame radiation interference can be reduced, and it is guaranteed that the infrared temperature measuring sensor can still have a stable measuring result and accurate testing precision under the flame interference condition.

Description

technical field [0001] The invention relates to an infrared temperature measuring device and a gas stove using the infrared temperature measuring device. Background technique [0002] Along with the raising of people's living standard, household gas cooker is popularized gradually in my country. Excessive combustion of domestic gas stoves will damage the heated pots and food, and may cause a fire, which is a major hidden danger to the safety of the kitchen. [0003] As users have higher and higher requirements for cooking experience, intelligent control and cooking safety, how to accurately measure the temperature of food in the pot, further prevent food from drying out, and realize the intelligent reminder function of intelligent recipes is an important issue now. research direction. [0004] Existing methods for measuring the temperature of food in gas stoves mainly include: NTC temperature measurement at the bottom of the pot, infrared temperature measurement at the bot...

AI Technical Summary

Problems solved by technology

[0005] The NTC temperature measurement at the bottom of the pot needs to change the structure of the burner and open holes in the inner ring, which will easily lead to uneven temperature at the bottom of the pot; the interference of high-temperature flue gas and flame in the inner ring will also affect the temperature measurement accuracy; and the adaptability of the pot is poor. If the bottom of the pot is concave, the ceramic pot will affect the temperature measurement accuracy; the infrared temperature measurement of the bottom of the pot still needs to be in contact with the bottom of the pot, and the structure of the burner needs to be changed. Practical use may easily lead to inaccurate temperature measurement results, and the high-temperature smoke and flame at the bottom of the pot may also easily affect the temperature measurement accuracy
