Embodiment 1
[0046] see figure 1 , figure 1 It is a flowchart of a gas leakage protection control method for an electric pressure cooker provided by an embodiment of the present invention. Such as figure 1 As shown, the method includes:
[0047] Step S101, obtaining the temperature in the pot in real time;
[0048] Specifically, the temperature in the pot is obtained in real time through a temperature sensing package arranged inside the upper cover of the electric pressure cooker.
[0049] Step S102, after the temperature in the pot reaches the preset temperature, record the time required for each increase of the first temperature;
[0050] Specifically, the preset temperature is lower than the boiling point temperature of water at the current altitude, that is to say, the preset temperature is a certain temperature before the electric pressure cooker enters the boosting phase. If the boiling temperature of water at the current altitude is 100 degrees Celsius, the preset temperature m...
Embodiment 2
[0059] see figure 2 , figure 2 It is a flow chart of another electric pressure cooker air leakage protection control method provided by the embodiment of the present invention. Such as figure 2 As shown, the method includes:
[0060] Step S201, obtaining the temperature in the pot in real time;
[0061] Step S202, after the temperature in the pot reaches the preset temperature, record the time required for each increase of the first temperature;
[0062] Specifically, the preset temperature is lower than the boiling temperature of water at the current altitude.
[0063] Step S203, calculating the time required for each temperature point to rise to the second temperature within the interval from the preset temperature to the current temperature in the pot, and determining the maximum time;
[0064] Specifically, the second temperature is greater than the first temperature.
[0065] Step S204, if the current temperature in the pot has not risen to the first temperature ...

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...
