Sonar-controlling intelligent electric pressure cooker

Abstract

The invention provides a sonar-controlling intelligent electric pressure cooker. An inner pot is arranged in a cooker body, a pot cover on the cooker body can open or close the cooker body, the gap between the pot cover and the inner pot is sealed through a sealing ring to enable the cooker body, the inner pot and the pot cover to form a sealed cavity when the pot cover is closed, and a float valve, a safety valve and an exhaust valve are arranged on the pot cover and are communicated with the sealed cavity; a heating unit is arranged in the bottom end of the cooker body and located under theinner pot, a control unit and a sonic sensor are arranged in the interlayer of the cooker body, the heating unit and the sonic sensor are respectively connected with the control unit and are controlled through the control unit, the electric pressure cooker at the operation state coverts sonic signals collected through the sonic sensor to electrical signals which are sent to the control unit, the received electrical signals are analyzed and processed through the control unit, and working instructions after analysis and processing are sent to the heating unit. The sonar-controlling intelligent electric pressure cooker is capable of realizing boiling cooking and good in safety performance.

Description

technical field [0001] The invention relates to the technical field of home appliances, in particular to a sonar-controlled intelligent electric pressure cooker. Background technique [0002] The traditional electric pressure cooker controls the working pressure of the electric pressure cooker through the mechanical pressure switch inside the electric pressure cooker. This control method makes the working pressure of the electric pressure cooker single, and different ingredients are cooked under one pressure condition, and the cooking process There is no boiling process in the cooking process, which will cause the rice to turn green due to too high pressure when cooking, and the quality of the soup will be too light due to the lack of boiling during the cooking process. In addition, the traditional electric pressure cooker cannot collect signals after the pressure is released due to abnormal pressure, and it can continue to be used after the abnormality occurs, which has cer...

[0002] The traditional electric pressure cooker controls the working pressure of the electric pressure cooker through the mechanical pressure switch inside the electric pressure cooker. This control method makes the working pressure of the electric pressure cooker single, and different ingredients are cooked under one pressure condition, and the cooking process There is no boiling process in the middle, which will cause the rice to turn green due to too high pressure when cooking, and the quality of the soup will be too light due to the lack of boiling during the cooking process.

In addition, the traditional electric pressure cooker cannot collect signals after the pressure is released due to abnormal pressure, and it can continue to be used after the abnormality occurs, which has certain potential safety hazards
