As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

As shown in fig. 1 to 4, the cooking appliance of the present embodiment includes a pot body 10, a pot cover 20, and a pressure limiting valve assembly 40. Wherein, the pot body 10 is used for containing food to be cooked. A heating device is arranged in the pot body 10. The pot cover 20 is covered on the pot body 10, and an exhaust passage 30 is arranged in the pot cover 20. The pressure limiting valve assembly 40 includes a pressure limiting valve body 41 and a pressure regulating structure 42. The pressure limiting valve body 41 is matched with the exhaust channel 30, and the pressure regulating structure 42 is matched with the pressure limiting valve body 41 to change the pressure applied by the pressure limiting valve body 41 to the exhaust channel 30. The control method of the cooking appliance comprises the following steps:

step S1: the pressure regulating structure 42 makes the pressure exerted by the pressure limiting valve body 41 on the exhaust passage 30 be at a first preset pressure P1, and the heating device heats with a first heating power, so that the pressure in the pot body 10 is greater than or equal to the first preset pressure P1, and the liquid in the pot body 10 is boiled;

step S2: the pressure regulating structure 42 makes the pressure exerted by the pressure limiting valve body 41 on the exhaust passage 30 be at a second preset pressure P2 different from the first preset pressure P1, and the heating device heats with a second heating power different from the first heating power, so that the pressure in the pot body 10 is greater than or equal to the second preset pressure, and the liquid in the pot body 10 is boiled.

By applying the technical scheme of the embodiment, the cooking appliance can respectively boil under the first preset pressure P1 and the second preset pressure P2, so that the whole cooking process can be continuously boiled under different pressures. Above-mentioned structure makes cooking utensil's culinary art process more nimble, and culinary art effect is better simultaneously. Therefore, the technical scheme of the embodiment solves the problem that the electric pressure cooker in the prior art is poor in cooking effect.

As shown in fig. 4, in the solution of the present embodiment, the first preset pressure P1 is smaller than the second preset pressure P2. Specifically, in the preset cooking procedure, the liquid in the pot 10 is boiled at a first lower preset pressure P1 and then at a second higher preset pressure P2.

Preferably, in the present embodiment, the first preset pressure P1 is in the range of 20Kpa to 40 Kpa. The second preset pressure P2 is in the range of 90Kpa to 110 Kpa. Of course, the first preset pressure P1 and the second preset pressure P2 can be adaptively adjusted to other values.

Of course, the cooking appliance in the embodiment may have other cooking manners. Because the pressure regulating structure 42 in this embodiment can regulate the pressure applied to the exhaust passage 30 by the pressure limiting valve body 41, the cooking appliance can exhaust and boil under different pressures according to different food materials, thereby making the cooking effect better. As shown in fig. 5, the graph in fig. 5 shows another two cooking modes of the cooking appliance of the present embodiment, one is that the cooking appliance continues to exhaust and boil under the first preset pressure P1. The other is that the cooking utensil continues to boil under the second preset pressure P2.

And both ends of the first elastic member 43 are respectively abutted against the pressure regulating structure 42 and the pressure limiting valve body 41. When the pressure regulating structure 42 moves in the up-down direction, the amount of compression of the first elastic member 43 is changed to change the pressure applied by the first elastic member 43 to the pressure limiting valve body 41, thereby changing the pressure applied by the pressure limiting valve body 41 to the exhaust passage 30. Specifically, when the pressure regulating structure 42 moves downward, the amount of compression of the first elastic member 43 increases, and therefore the elastic force applied by the first elastic member 43 to the pressure limiting valve body 41 increases. Therefore, in the present embodiment, when the cooking appliance proceeds from step S1 to step S2 during the cooking process, the pressure adjusting structure moves downward, so that the second preset pressure P2 is greater than the first preset pressure P1.

Preferably, the first elastic member 43 in this embodiment is a spring.

As shown in fig. 3, in the present embodiment, the pressure limiting valve assembly 40 further includes a second elastic member 44, and the second elastic member 44 is disposed outside the pressure limiting valve body 41 and supports the pressure regulating structure 42. Specifically, the second elastic member 44 is a spring, and the diameter of the second elastic member 44 is larger than that of the first elastic member 43. The second elastic member 44 can support the pressure regulating structure 42, and can assist the pressure regulating structure 42 to reset.

In the solution of the present embodiment, as shown in fig. 3, the pressure limiting valve assembly 40 further comprises a valve seat 45 and a mounting cap 46. The valve seat 45 is fixed in the lid 20, and the exhaust passage 30 is provided in the valve seat 45. The mounting cap 46 covers the valve seat 45, and a mounting space is defined between the mounting cap 46 and the valve seat 45. The pressure limiting valve body 41, the pressure regulating structure 42, the first elastic member 43, and the second elastic member 44 are disposed in the installation space. Wherein, be provided with on the roof of installation cap 46 and dodge hole 461, pressure regulating structure 42 includes plate body 421 and the top cap 422 that pushes away that sets up on plate body 421, and plate body 421 and the inboard butt of the roof of installation cap 46 push away top cap 422 and pass and dodge hole 461. Specifically, when the exhaust pressure is adjusted, the driving structure presses the push top cap 422 to move the plate body 421 downward, so that the compression amount of the first elastic member 43 is changed. The driving structure can be a lever, a swing rod or an electromagnetic valve.

As shown in fig. 4 and 5, in the solution of the present embodiment, the control method includes step S3, step S3 is used for the exhaust phase. Specifically, in step S3, the drive structure does not act on the ejector cap 422. At this time, the second elastic member 44 supports the plate body 421 while the first elastic member 43 is not in a compressed state. At this time, the upper end of the pressure limiting valve body 41 is not subjected to the elastic force of the first elastic member 43, and the exhaust passage 30 is in an exhaust state, so that the pressure in the pot body 10 is reduced. Further, in step S3, the heating device is in a state of stopping heating.
