Electric pressure cooker air leakage protection control method and device and electric pressure cooker

Abstract

The invention discloses an electric pressure cooker air leakage protection control method and device and an electric pressure cooker. The method comprises the steps that the temperature in the cooker is acquired in real time; when the temperature in the cooker reaches a preset temperature, time needed by increasing a first temperature every time is recorded, and the preset temperature is lower than the boiling point temperature of water at the current altitude; time needed by increasing a second temperature of every temperature point within the interval ranging from the preset temperature to the current temperature in the cooker is calculated, and the maximum consumed time is determined, and the second temperature is higher than the first temperature; if the current temperature in the cooker is not increased to the first temperature yet through the maximum consumed time, the electric pressure cooker is controlled to stop heating, and a display screen is controlled to display a fault code corresponding to air leakage. According to the electric pressure cooker air leakage protection control method and device and the electric pressure cooker, air leakage of the electric pressure cooker can be found in time to execute air leakage protection operation, therefore, the electric pressure cooker is prevented from being damaged, and safety accidents are prevented from occurring.

Description

technical field [0001] The invention relates to the field of control technology, in particular to an electric pressure cooker air leakage protection control method, device and electric pressure cooker. Background technique [0002] At present, many electric pressure cookers have separate and detachable lids and missing sealing rings. For temperature-controlled or temperature-pressure dual-control electric pressure cookers, if there is no structure for missing sealing rings, the user will not be able to use the electric pressure cooker. , still able to heat and work, but after the water boils, because there is no sealing ring in the pot, the air leaks in the pot, so that the pressure cannot rise, and it is always in a boiling state. If you continue to heat according to the normal procedure, the generated steam will pass through If the gap enters the inside of the pot body and the steel cover, the plastic shell will be easily deformed by high temperature, and it may also cause...

Problems solved by technology

[0002] At present, many electric pressure cookers have separate and detachable lids and missing sealing rings. For temperature-controlled or temperature-pressure dual-control electric pressure cookers, if there is no structure for missing sealing rings, the user will not be able to use the electric pressure cooker. , still able to heat and work, but after the water boils, because there is no sealing ring in the pot, the air leaks in the pot, so that the pressure cannot rise, and it is always in a boiling state. If you continue to heat according to the normal procedure, the generated steam will pass through If the gap enters the inside of the pot body and the steel cover, the plastic shell will be easily deformed by high temperature, and it may also cause water to enter the controller part, resulting in control failure, and may even cause dangers such as short circuit.
