As shown in fig. 1 and 2, the cooking appliance of the present embodiment includes a pot body 10, a pressure limiting valve 40 of a pot cover 20, and a driving device 50. Wherein the pan body 10 is used for containing food to be cooked. The pot cover 20 is arranged on the pot body 10, and the pot cover 20 is provided with an exhaust structure 30 communicated with the interior of the pot body 10. The pressure limiting valve 40 is arranged on the exhaust structure 30, the driving device 50 is matched with the pressure limiting valve 40, and the driving device 50 pushes the pressure limiting valve 40 and enables the pressure limiting valve 40 to return.

By applying the technical scheme of the embodiment, the cooking utensil comprises the driving device 50, and the driving device 50 can push the pressure limiting valve 40. The driving device 50 can adjust the position of the pressure limiting valve 40 in the process of pushing the pressure limiting valve 40, and adjust the pressure limiting valve from an inclined state to a vertically installed state, so as to realize resetting. Therefore, the technical scheme of the embodiment solves the problem that the electric pressure cooker in the prior art cannot be installed in place due to the pressure limiting valve, and then the exhaust pipe leaks air during cooking.

Specifically, the driving device 50 may push the pressure limiting valve 40 in such a manner that the pressure limiting valve 40 is pushed to rotate about its axis, or the pressure limiting valve 40 is pushed to move up and down. During the movement of the pressure limiting valve 40, the pressure limiting valve 40 may correct its own position. If the pressure limiting valve 40 is installed with a deflection in the position of the pressure limiting valve 40, the position of the pressure limiting valve 40 can be adjusted during the pushing movement of the pressure limiting valve 40 by the driving device 50, and the pressure limiting valve 40 can be adjusted from the deflection to the return.

As shown in fig. 3, in the technical solution of the present embodiment, when the driving device 50 pushes the pressure limiting valve 40, the pressure limiting valve 40 moves in a direction away from the exhaust structure 30 and exhausts the exhaust structure 30. That is, the driving device 50 can function to push the pressure limiting valve 40 back, and also can function to push the pressure limiting valve 40 and make the exhaust structure. The above structure makes the driving device 50 adopt the structure for pushing the pressure limiting valve 40 to exhaust in the prior art, so that a new driving structure is not needed to be added, the product structure is simplified, and the production cost is reduced. Of course, the driving device 50 may be a separate structure, that is, the driving device 50 may only play a role in pushing the pressure limiting valve 40 to reset. The driving device 50 may be in the form of a push rod, an electromagnetic valve, etc.

Further, in the technical solution of the present embodiment, the specific time point when the driving device 50 pushes the pressure limiting valve 40 may be controlled by a control system, for example, before the cooking appliance is pressed up, the control system makes the driving device 50 push the pressure limiting valve 40 and resets the pressure limiting valve 40. Of course, the driving device 50 may also be controlled manually, for example, a driving button may be disposed outside the pot body 10 or the pot cover 20, and when the user presses the driving button, the driving device 50 pushes the pressure limiting valve 40 to reset.

As shown in fig. 4, in the technical solution of this embodiment, the exhaust structure 30 is an exhaust pipe, the pressure limiting valve 40 is sleeved on the exhaust pipe, and the pressure limiting valve 40 can rotate around its axis, the cooking appliance further includes a valve seat 60 disposed at the exhaust pipe, the pressure limiting valve 40 is accommodated in the valve seat 60, a lifting structure is disposed between the pressure limiting valve 40 and the valve seat 60, when the pressure limiting valve 40 is pushed to rotate by the driving device 50, the pressure limiting valve 40 rises under the action of the lifting structure and exhausts the exhaust pipe, and when the driving device 50 is separated from the pressure limiting valve 40, the pressure limiting valve 40 falls back by gravity. Specifically, the driving device 50 may push the pressure limiting valve 40 to rotate, and in this process, the pressure limiting valve 40 is lifted and separated from the exhaust pipe by the lifting structure, so that the exhaust pipe is exhausted. When the driving device 50 is separated from the pressure limiting valve 40, the pressure limiting valve 40 falls back by gravity. The pressure limiting valve 40 can be adjusted in position during the ascending and descending of the pressure limiting valve 40, that is, the pressure limiting valve 40 can be returned during the pushing of the pressure limiting valve 40 by the driving device 50.

As shown in fig. 5 and 6, in the technical solution of the present embodiment, an installation notch 41 is provided on the lower end surface of the pressure limiting valve 40, and the lifting structure includes a guide surface 71 and a rib 72. Wherein the guide surface 71 is provided on the side wall of the mounting recess 41. The bead 72 is disposed within the valve seat 60. When the pressure limiting valve 40 is mounted in the valve seat 60, the rib 72 is located in the mounting notch 41, and when the driving device 50 pushes the pressure limiting valve 40 to rotate, the guide surface 71 abuts against the rib 72 and lifts the pressure limiting valve 40. Preferably, the mounting notch 41 is a triangular notch, and one inclined surface of the triangular notch forms the guide surface 71. When the pressure limiting valve 40 is installed, the installation notch 41 is buckled on the convex rib 72. When the drive means 50 pushes the pressure limiting valve 40 to rotate, the guide surface 71 slides relative to the rib 72, i.e. the pressure limiting valve 40 is gradually raised under the interaction of the guide surface 71 and the rib 72. When the driving device 50 is separated from the pressure limiting valve 40, the pressure limiting valve 40 descends back.

As shown in fig. 3 and 5, in the technical solution of the present embodiment, the driving device 50 is an electromagnetic valve, and the outer sidewall of the pressure limiting valve 40 is provided with a push handle 42 that is matched with a push rod of the electromagnetic valve. Specifically, after the electromagnetic valve is electrified, the push rod of the electromagnetic valve extends out. The push rod is extended and then is matched with the push handle 42 to push the pressure limiting valve 40 to rotate. After the solenoid valve is de-energized, its push rod retracts and disengages from push handle 42. The pressure limiting valve 40 falls back by gravity at this time. Preferably, the valve seat 60 is provided with a relief opening for relieving the push handle 42.

Specifically, the pressure limiting valve 40 can be subjected to a plurality of position adjustments by pushing the pressure limiting valve 40 by the time driving device 50 a plurality of times, and the pressure limiting valve 40 is ensured to be in a reset state.

Preferably, the control method of the present embodiment further includes an up-pressing stage, and the correction stage is performed before the up-pressing stage.
