In one embodiment of the present invention, the control device 50 may be an electric control board of the cooking appliance 100.
Specifically, before the cooking appliance enters the cooking program, a vacuum detection stage is first entered to detect each electronic component in the vacuum system, and if it is detected that there is an abnormality in the vacuum system, the control device 50 simultaneously controls the vacuum pump 31, the solenoid valve 33 and the driving assembly 42 to be powered off and stopped, the vacuum function in the cooking program is stopped, and the cooking appliance performs a non-vacuum cooking program, for example, a rice cooking function.

It should be noted that, when it is detected that there is an abnormality in the vacuum system, the sequence of controlling the vacuum pump 31, the electromagnetic valve 33 and the driving assembly 42 to stop working after power is cut off is not required, for example, the vacuum pump 31 is controlled to stop working after power is cut off, the electromagnetic valve 33 is controlled to stop working after power is cut off, and finally the driving assembly 42 is controlled to stop working; for another example, the solenoid valve 33 is first controlled to be powered off to stop working, then the vacuum pump 31 is controlled to be powered off to stop working, and finally the driving assembly 42 is controlled to stop working. Similarly, two or three of the three may also be controlled to stop working at the same time, which is not illustrated here.
According to an embodiment of the present invention, the control device 50 is further configured to detect whether there is an abnormality in the vacuum system when the cooking appliance enters the vacuum operation stage, and further detect whether there is an abnormality in the vacuum pump 31 when there is an abnormality in the vacuum system, wherein if there is an abnormality in the vacuum pump 31, the control device 50 controls the vacuum pump 31 to stop operating, then controls the electromagnetic valve 33 to stop operating, and controls the driving assembly 42 to stop operating, and if there is no abnormality in the vacuum pump 31, the control device 50 controls the vacuum pump 31, the electromagnetic valve 33 and the driving assembly 42 to stop operating simultaneously.
Specifically, when the control device 50 detects that there is an abnormality in the vacuum system while the cooking appliance is performing the cooking function, it is further determined whether there is an abnormality in the vacuum pump 31. If there is an abnormality in the vacuum pump 31, the control device 50 controls the vacuum pump 31 to be immediately powered off and stop operating, and controls the solenoid valve 33 to be powered off after the vacuum pump 31 is powered off, and the time for powering off and stopping operating the driving assembly 42 is not limited, for example, the vacuum pump 31 may be powered off at the same time, the vacuum pump 31 may be powered off again after being powered off, and the solenoid valve 33 may be powered off again after being powered off. Thereby make the negative pressure between vacuum pump and the solenoid valve in time let out, prevent that the vacuum pump from continuously receiving the effect of negative pressure to when maintaining, the connecting pipe of being convenient for is dismantled from vacuum pump and solenoid valve.
If there is no abnormality in the vacuum pump 31, the control device 50 controls the vacuum pump 31, the solenoid valve 33 and the driving assembly 42 to be simultaneously de-energized, and controls the cooking appliance to perform a non-vacuum cooking process. It should be noted that there is no requirement for the sequence of controlling the vacuum pump 31, the solenoid valve 33 and the driving assembly 42 to stop working after power is cut off, for example, the driving assembly 42 is controlled to stop working first, then the vacuum pump 31 is controlled to stop working, and finally the solenoid valve 33 is controlled to stop working.

Therefore, the cooking appliance provided by the embodiment of the invention can detect the vacuum system when the cooking appliance enters a vacuum detection stage or a vacuum working stage, and take corresponding measures when the vacuum system is abnormal, so as to ensure that a user can normally use other functions, and greatly improve the user experience.
According to an embodiment of the present invention, the control device 50 is further configured to control the cooking appliance to send out a prompt message when there is an abnormality in the vacuum system. That is, when it is detected that there is an abnormality in the vacuum system, the control device 50 controls the cooking appliance to emit prompt information, such as a red light emitted by the indicator light and a flashing light to prompt the user, or a voice prompt to prompt the user to perform maintenance.
In some embodiments, the drive assembly 42 may include an electromagnet 421 and a pushrod 422. The electromagnet 421 is disposed on the cover 20, the push rod 422 is movably disposed on the electromagnet 421 along a horizontal direction (a front-back direction as shown in fig. 4), and one end (a back end as shown in fig. 4) of the push rod 422 can drive the plugging member 41 to move.
That is, when the vacuum system is abnormal, the control device 50 controls the driving assembly 42 to be powered off and stop, that is, controls the electromagnet 421 to be powered off, so that the blocking piece 41 cannot move to the blocking position, and the cooking cavity 11 is not in the closed state.
As a specific example, the vacuum system is abnormal during the inspection stage. As shown in fig. 5, before entering a certain cooking function, the vacuum rice cooker detects each electronic component of the vacuum rice cooker, and if it is detected that a problem occurs in the vacuum system, the vacuum pump 31, the electromagnetic valve 33 and the electromagnet 421 are all controlled to be powered off and stop working, and the three stop working sequences are not required, the vacuum function stops in the cooking program, other functions are performed according to the original set program, and at this time, the cooking function is not influenced by the vacuum system and stops working.

Thereby make the negative pressure between vacuum pump and the solenoid valve in time let out, prevent that the vacuum pump from continuously receiving the effect of negative pressure to when maintaining, the connecting pipe of being convenient for is dismantled from vacuum pump and solenoid valve.
Further, according to an embodiment of the present invention, when there is an abnormality in the vacuum system, if there is no abnormality in the vacuum pump 31, the control device 50 controls the vacuum pump 31, the solenoid valve 33, and the driving assembly 42 to stop operating at the same time.
That is, there is no requirement for the sequence of controlling the vacuum pump 31, the solenoid valve 33 and the driving assembly 42 to stop working after power is cut off, for example, the driving assembly 42 is controlled to stop working first, then the vacuum pump 31 is controlled to stop working, and finally the solenoid valve 33 is controlled to stop working.
As a specific example, vacuum systems have problems during the working phase. As shown in fig. 6, when the vacuum rice cooker performs a certain cooking function, if it is detected that the vacuum system is abnormal during the operation process, it is determined whether the vacuum pump 31 is out of order. If the vacuum pump 31 is out of order, the vacuum pump 31 and the electromagnet 421 are immediately powered off, and the electromagnetic valve 33 is powered off after the vacuum pump 31 is powered off, it should be noted that the electromagnet 421 can also be powered off after the vacuum pump 31 is powered off, that is, the time for powering off the electromagnet 421 is not required. If the vacuum pump 31 is out of order (i.e., the solenoid valve 33 and/or the electromagnet 421 are out of order), the vacuum pump 31, the solenoid valve 33 and the electromagnet 421 are controlled to stop working after being powered off, and the sequence of the three stop working is not required, and the non-vacuum cooking stage is carried out.
