the duration of time that the first current is applied to the exhaust valve is recorded and recorded as the energization duration.
And judging whether the electrifying time length is greater than or equal to a second preset time length.
And judging that the electrifying time period is greater than or equal to the second preset time period, and stopping applying the first current to the exhaust valve.
In the above embodiment, in order to ensure the reliability of the air pump and the air extraction valve, a preset air extraction time length is preset, and if it is determined that the air extraction time length reaches the preset air extraction time length, the air extraction valve and the air extraction pump are controlled to stop working, and in addition, the first current is stopped being applied to the exhaust valve, so as to further reduce the power consumption of the whole machine in a vacuum state.
Wherein the second preset time is 30-240 seconds.
Example two:
as shown in fig. 3, the cooking appliance 100 is naturally cooled after being heated to generate vacuum, and when a vacuum related function is used, if it is detected that a user presses a fresh-keeping function button or enters a fresh-keeping stage after a cooking stage is executed under a certain cooking function, the heating assembly 150 heats the cooking part 170, the temperature in the sealed cooking part rises, and air in the sealed cooking part is gradually discharged through the float 130.
When pressure is generated in the sealed cooking part, the float 130 is pushed up, the detection device 140 detects the float 130 (or detects that the float 130 is pushed up), the heating assembly 150 stops heating, and the system counts the number of times the detection device 140 detects that the float 130 is pushed up to be N, wherein N is an integer greater than or equal to 1.
In the process of exhausting the gas in the cooking part 170, a second current may be applied to the electromagnetic coil 124 to apply a repulsive force to the valve body 126, the valve body 126 is lifted up and exhausted, the pressure in the sealed cooking part 170 is reduced, the float 130 drops down, the energization of the electromagnetic coil 124 is stopped, the valve body 126 also drops, the detecting device 140 does not detect the float 130 (or detects that the float 130 drops), the heating unit 150 heats the cooking part 170, the pressure in the sealed cooking part is increased, the float 130 is lifted up, the detecting device 140 detects the float 130, and the heating unit 150 stops heating.

When the float 130 drops down, the detecting device 140 does not detect the float 130, and a first current is applied to the electromagnetic coil 124 to apply an attractive force to the valve body 126, thereby sealing the exhaust passage and gradually bringing the sealed cooking portion into a vacuum state.
And (3) timing t for the sealing state of the cooking part, controlling the electromagnetic coil 124 to be powered off when the electrifying time of the electromagnetic coil 124 reaches a second preset time, wherein the numerical range of the second preset time is 30-600 seconds, and the valve core 126 is in a natural state.
