Control method, control device and cooking appliance

Abstract

The invention provides a control method, a control device and a cooking utensil. The control method is used for controlling the cooking utensil; a steam exhaust valve and a coil assembly are arranged on an upper cover of the cooking utensil, and a permanent magnet is arranged on the steam exhaust valve and can be subjected to acting force of a magnetic field generated when the coil assembly is electrified. The control method includes the steps that after the cooking utensil enters a steam exhaust stage, the electrification voltage of the coil assembly is controlled to be increased or decreased by a preset voltage value every first preset duration to change the acting force, which the permanent magnet is subjected to, of the magnetic field generated when the coil assembly is electrified so that the switching-on degree of the steam exhaust valve can be increased gradually. According to the control method, the switching-on degree of the steam exhaust valve is controlled by dynamically adjusting the electrification voltage, generated after the cooking utensil enters the steam exhaust stage, of the coil assembly; besides, the pressure in the cooking utensil is gradually decreased along with the increase of the steam exhaust duration, the switching-on degree of the steam exhaust valve is controlled to be increased, and thus the effect of rapid and stable steam exhaust and pressure decrease in the cooking utensil is achieved.

Description

technical field [0001] The invention relates to the field of kitchen utensils, and more specifically, to a control method, a control device and a cooking utensil. Background technique [0002] Existing cooking appliances, such as electric pressure cookers, usually realize the steam exhaust function of the electric pressure cooker by manually opening the steam exhaust valve on the electric pressure cooker after the cooking is completed, so as to discharge the water vapor in the pot. The medium pot maintains a certain preset pressure, which causes the pressure in the pot to decrease instantly when the user opens the exhaust valve, which easily causes the food in the pot to overflow along the steam channel on the exhaust valve, and at the same time makes it impossible for the user to close the exhaust valve. The steam valve affects the user's experience; some existing electric pressure cookers slow down the overflow of food in the pot when the exhaust valve is opened to a certa...

[0002] Existing cooking appliances, such as electric pressure cookers, usually realize the steam exhaust function of the electric pressure cooker by manually opening the steam exhaust valve on the electric pressure cooker after the cooking is completed, so as to discharge the water vapor in the pot. The medium pot maintains a certain preset pressure, which causes the pressure in the pot to decrease instantly when the user opens the exhaust valve, which easily causes the food in the pot to overflow along the steam channel on the exhaust valve, and at the same time makes it impossible for the user to close the exhaust valve. The steam valve affects the user's experience; some existing electric pressure cookers slow down the overflow of food in the pot when the exhaust valve is opened to a certain extent by controlling the opening and closing of the exhaust valve. However, the above method will also cause The exhaust time is too long, the exhaust speed is uncontrollable, etc., and there is no guarantee that there will be no food spillage when the exhaust valve is opened when cooking a large amount of porridge
