Cooker with non-contact sensing device and control method for the cooker

Abstract

The invention discloses a cooking utensil with a non-contact sensing device. The cooking utensil comprises a panel, a burner and the non-contact sensing device, wherein the sensing device comprises a temperature measurement module and a distance measurement module; the cooking utensil is characterized in that a light transmitting area is formed on the panel, the sensing device is arranged below the panel, and corresponds to the light transmitting area of the panel, and a through hole for a detection signal of the sensing device to pass through is formed in the middle position of the part, located above the panel, of the burner. The invention also discloses a control method of the cooking utensil. The sensing device with the temperature measurement module and the distance measurement module is arranged below the panel, and the detection signal is sent out from a place below the panel and passes through the burner, thus flame disturbance of the burner can be avoided, a measured result is accurate, and further the work of the cooking utensil is accurately and automatically controlled.

Description

technical field [0001] The invention relates to a cooker, especially a cooker with a non-contact sensing device, and a control method for the cooker. Background technique [0002] For a long time, people have paid great attention to the safety of gas stoves, so various protective devices are usually installed in gas stoves. During the use of gas stoves, when the flame is extinguished by wind or boiling water overflows, it will cause gas leakage, which will cause safety accidents. Therefore, it is very necessary to introduce a temperature sensing device at the bottom of the pot to avoid dry burning. , empty cooking, and better control over the size of the fire to match a variety of cooking processes. [0003] At present, existing gas cookers rarely use technologies such as pot temperature monitoring and pot usage status monitoring. Even if they are used, they use a mechanical contact structure to directly measure the bottom of the pot. Errors in the use of this method Large...

AI Technical Summary

Problems solved by technology

In this kind of gas cooker, the infrared sensor is installed on one side of the cooker to detect the presence or absence of the pot from the side. The size and shape of tools are different. When detecting from the side, it is not only easy to make the detection result deviate, it is more likely to cause false detection, and it is also easy to be interfered by other objects. It also has very high requirements for the position of the sensor, and the sensor settings may even cause inconvenience to the cooking process
