In-pot residue detection device and electric rice cooker

Abstract

The invention relates to an in-pot residue detection device and an electric rice cooker. The in-pot residue detection device comprises a controller, a signal transmitter and a signal receiver; the signal transmitter is used for transmitting signals to the bottom of the electric rice cooker; the signal receiver is used for receiving signals which are transmitted by the signal transmitter and reflected by the bottom of the electric rice cooker and transmitting the signals to the controller; and the controller is electrically connected with the signal receiver and is used for generating a residuedetection result according to the signals received by the signal receiver. The controller compares electric signals converted from actually received reflection signals with electric signals convertedfrom reflection signals received when no residue exists at the bottom of the cooker, so that the detection of residues in the cooker can be realized, and a data basis is provided for the next actionof the electric rice cooker.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detection device for residues in a pot and an electric rice cooker. Background technique [0002] With the continuous development of smart home technology and the continuous improvement of people's living standards, home appliances that can realize fully automated smart work have become a research hotspot. For example, people hope that the smart rice cooker can realize the automatic cooking function. In the process of implementation, the inventor found at least the following disadvantages: during the cooking process of the automatic electric rice cooker, if there is more water or rice left in the pot, during secondary cooking, for example, when cooking rice, the normal cooking ratio should be followed. Adding rice and water to the pot may cause too much water to be added for the second time. The water overflows the inner pot of the rice cooker and flows to the heater at the ...

Problems solved by technology

In the process of implementation, the inventor found at least the following disadvantages: during the cooking process of the automatic electric rice cooker, if there is more water or rice left in the pot, during secondary cooking, for example, when cooking rice, the normal cooking ratio should be followed. Adding rice and water to the pot may cause too much water to be added for the second time. The water overflows the inner pot of the rice cooker and flows to the heater at the bottom of the pot. When cooking and heating, it will cause a safety accident.
