Problems solved by technology

If the solenoid valve fails and the solenoid valve cannot be opened when the air extraction device is working, there will be no negative pressure in the pot, which will affect the cooking effect, and the air extraction device will be easily damaged if it is in a high-load working state for a long time; if the air extraction device stops working When the solenoid valve is not closed, the hot air in the pot will be discharged through the exhaust device during the cooking process, which may cause damage to the exhaust device.

Abstract

The invention discloses a method, a device and a cooking utensil for detecting the failure of a solenoid valve. The method includes: obtaining the change rate of the working current of the air extraction device or the first preset value of the air extraction of the air extraction device under different control states of the electromagnetic valve. The working current after a set time or the negative pressure value in the cooking cavity after the second set time preset by the air extraction device; according to the control state, and the rate of change of the working current or the working current or negative pressure value, judge Whether the solenoid valve fails. This method can accurately judge whether the solenoid valve is invalid according to the change rate of the working current of the solenoid valve under different control states, the working current, and the negative pressure value in the cooking cavity, so as to facilitate the maintenance of the solenoid valve and avoid the failure of the solenoid valve Valve failure affects cooking results and damages the extraction unit.

Description

technical field [0001] The present invention relates to the technical field of electrical appliances, in particular to a detection method for electromagnetic valve failure, a detection device for electromagnetic valve failure, a cooking utensil, an electronic device and a non-transitory computer-readable storage medium. Background technique [0002] At present, in order to improve the cooking effect and fresh-keeping effect of the cooking utensil, an air extraction device and a solenoid valve are added to the cooking utensil to realize the negative pressure function. [0003] The electromagnetic valve is opened when the air extraction device is working, and the electromagnetic valve is closed when the air extraction device stops working. If the solenoid valve fails and the solenoid valve cannot be opened when the air extraction device is working, there will be no negative pressure in the pot, which will affect the cooking effect, and the air extraction device will be easily ...
