Pressure cookware and method and device for controlling uncovering of pressure cookware during cooking

Abstract

The invention discloses pressure cookware and a method and device for controlling uncovering of the pressure cookware during cooking. The method comprises the steps of generating an instruction for uncovering during cooking and acquiring a time point generating the instruction for uncovering during cooking when an exhaust unit is triggered for exhausting and it is detected that parameters of steam discharged by the exhaust unit meet preset requirements; judging the cooking stage of the time point generating the instruction for uncovering during cooking, so as to calculate the total time for the pressure cookware to main pressure; calculating the time required for pressure maintaining after the pressure cookware is covered according to the total time for the pressure cookware to main pressure; and controlling the pressure cookware after the pressure cookware is covered according to the time required for pressure maintaining after the pressure cookware is covered. In this way, follow-up control over the pressure cookware can be achieved according to the cooking stage of the time point of uncovering during cooking, the effects of cooking with different food materials are guaranteed, and user requirements are met.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a control method for opening a cover of a pressure cooking appliance, a control device for opening a cover of a pressure cooking appliance, and a pressure cooking appliance. Background technique [0002] The current pressure cooking appliances such as electric pressure cooker, after selecting the relevant function menu, the product starts to go through the stages of heating, boiling, product pressure, pressure maintaining, depressurization, cooking end, etc. However, if one menu cooking needs to cook multiple foods (such as tendons, radishes, green vegetables, etc.), and the cooking time and pressure required for tendons, radishes, and vegetables are different, and the lid cannot be opened after the product is pressured (for example, there is a self-locking between the float and the lid of the electric pressure cooker product) structure, after the product ...

[0002] The current pressure cooking appliances such as electric pressure cooker, after selecting the relevant function menu, the product starts to go through the stages of heating, boiling, product pressure, pressure maintaining, depressurization, cooking end, etc. However, if one menu cooking needs to cook multiple foods (such as tendons, radishes, green vegetables, etc.), and the cooking time and pressure required for tendons, radishes, and vegetables are different, and the lid cannot be opened after the product is pressured (for example, there is a self-locking between the float and the lid of the electric pressure cooker product) structure, after the product starts to work, the float will lock the lid of the pot to ensure the safety of the user, and the lid cannot be opened if there is pressure), it is necessary to put all the ingredients into the pot before the electric pressure cooker starts to work, until the cooking is over, this As a result, ingredients such as tendons, radishes, and vegetables must be cooked with the same cooking time and pressure, which cannot satisfy all kinds of ingredients with better cooking effects. When the tendon is not cooked
