Cooker with temperature measurement function

Abstract

The invention discloses a cooker with temperature measurement function. The cooker comprises a cooker base, heaters and a pan lining, wherein the heaters and the pan lining are on the cooker base; a temperature sensing LC oscillating circuit for sensing the temperature of the pan lining is arranged on the pan lining; a temperature identification module is arranged on the cooker base; the temperature sensing LC oscillating circuit comprises an oscillating coil L1 and a temperature sensing capacitor CT; the temperature identification module comprises a controller and an exciting / sensing coil L2; an exciting drive circuit, a state switching circuit and a frequency detection circuit are connected onto the exciting / sensing coil L2, and the exciting / sensing control of separated temperature measurement of the cooker is achieved. The cooker with the temperature measurement function is simple and convenient in arrangement; the temperature sensing LC oscillating circuit is in contact with an object to be measured; the sensitivity is high; the temperature identification module is not in contact with the object to be measured; the service lives of chips and components on the temperature identification module are easily prolonged.

Description

[technical field] [0001] The invention relates to a cooker with a temperature measuring function. [Background technique] [0002] In daily life and industrial production process, it is often necessary to measure the temperature of various objects. Temperature is a very important index parameter in many technical fields. In many fields such as industry, medical treatment, military affairs and life, especially the internal temperature of objects under some sealed conditions, temperature measuring devices are required to monitor the temperature. [0003] Temperature measurement technology is divided into two categories: contact measurement and non-contact temperature measurement. Contact temperature measurement requires the sensor to be close to the surface of the object to be measured, and there is a line connection between the measurement circuit and the sensor. Commonly used contact temperature measurement technologies include thermocouple temperature measurement, thermist...

AI Technical Summary

Problems solved by technology

[0004] However, there are some occasions where neither the commonly used contact temperature measurement technology nor the infrared non-contact temperature measurement method can be used.

Measuring temperature while cooking, for example, is subject to many limitations

The temperature measurement inside the pot involves hygiene and cleaning issues, the external temperature measurement has high-temperature flame problems, and the infrared temperature measurement has oil pollution and smoke problems
