It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments according to the present application. 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 3, the present embodiment provides a control method of a cooking appliance. Wherein, the cooking appliance comprises a pot body 10, a pot cover 20, an exhaust passage 30 and a pressure limiting valve assembly 40. Wherein, the pot body 10 is used for containing food to be cooked. The pot cover 20 is disposed on the pot body 10, and the above-mentioned exhaust passage 30 and the pressure limiting valve assembly 40 engaged with the exhaust passage 30 are disposed in the pot cover 20. Wherein the pressure limiting valve assembly 40 is configured to apply either a first exhaust pressure or a second exhaust pressure to the exhaust passage 30, the first exhaust pressure being less than the second exhaust pressure. Further, the control method comprises a heating stage, a pressure maintaining stage and an exhaust stage which are sequentially carried out. The pressure maintaining stage comprises the following steps in sequence:

step S11: the pressure limiting valve assembly 40 applies a first exhaust pressure to the exhaust passage 30 to heat and enable the pressure in the pot body 10 to be larger than the first exhaust pressure so as to exhaust the exhaust passage 30;

step S12: the pressure limiting valve assembly 40 applies a second exhaust pressure to the exhaust passage 30 to heat and make the pressure inside the pot body 10 greater than the first exhaust pressure and less than the second exhaust pressure, so that the exhaust passage 30 does not exhaust.

With the technical solution of the present embodiment, since the pressure limiting valve assembly 40 is configured to be able to apply the first exhaust pressure and the second exhaust pressure to the exhaust passage 30, combined cooking at different pressures can be performed when cooking is performed, thereby making the cooking manner more diversified. Secondly, when the pressure maintaining stage is carried out, the exhaust pressure of the pressure limiting valve assembly 40 is controlled, the exhaust channel 30 is firstly exhausted, and the pressure cooking is carried out when the exhaust channel 30 does not exhaust, so that impurities in the food can be discharged to the outside, and the taste of the food is better. Therefore, the technical scheme of the embodiment solves the problems that the electric pressure cooker in the prior art is poor in cooking diversity and poor in food taste.

In this instance, in the above step S11, since the pressure inside the pot body 10 is greater than the first exhaust pressure, the exhaust passage 30 can exhaust air, and thus the foreign substances in the food can be exhausted through the exhaust passage 30.

In this embodiment, in the step S12, since the pressure inside the pot 10 is greater than the first exhaust pressure and less than the second exhaust pressure, and the pressure limiting valve assembly 40 applies the second exhaust pressure to the exhaust channel 30, the exhaust channel 30 does not exhaust. At this time, the food can be pressure cooked, and the taste of the food is better.

As shown in fig. 1, in the solution of the present embodiment, the pressure maintaining stage further includes the following steps performed after step S12,

step S13: the pressure limiting valve assembly 40 applies a first exhaust pressure to the exhaust passage 30 to heat and make the pressure inside the pot body 10 greater than the first exhaust pressure, so as to exhaust the exhaust passage 30.

Preferably, the above step S11 lasts for a time in the range of 3 to 5 minutes. The above step S12 lasts for a time in the range of 1 to 2 minutes. The above step S13 lasts in the range of 3 to 8 minutes.

Preferably, the first exhaust pressure is in the range of 20KPa to 40 KPa. The second exhaust pressure mentioned above is in the range of 60KPa to 80 KPa. Further preferably, the first exhaust pressure is 30KPa and the second exhaust pressure is 70 KPa.

Of course, the above parameters can be adaptively adjusted by those skilled in the art.

The control method of the cooking appliance in the embodiment is particularly suitable for cooking, and specifically, the first exhaust pressure is 30KPa, and the second exhaust pressure is 70KPa for example.

In step S11, the cooking appliance is turned to half power for continuous heating and then vented for about 3-5 minutes. The main purpose of step S11 is to discharge chlorine gas and the like in the water, and to discharge a part of the water at the same time. In the process, if the water volume is large, the internal pressure is more than 30KPA, the 30KPA pressure limiting valve is jacked up by the air pressure, and therefore the overflow risk cannot be generated. In step S12, the cooking device is continuously heated at half power, and the pressure in the cooker is set to be lower than 50KPA (45 KPA, 40KPA, selected according to the taste desired by the consumer), the pressure limiting valve is not vented, and the heating is stopped when the pressure exceeds the pressure. The main purpose of this process is to raise the temperature in the pot and make the rice more fragrant. This process lasts about 1-2 minutes. In step S13, the heating is continued at half power and the exhaust passage 30 is exhausted, which lasts for about 3-8 minutes. The process mainly aims at discharging excessive water in the rice, so that the cooked rice is chewy and has better taste. By the cooking method, the cooked rice has better taste and is chewy than common pressure cookers.

In this embodiment, the heating phase comprises: step S20 is heating and the pressure inside the pot 10 reaches the first exhaust pressure. Specifically, in the heating stage, when the cooking utensil is heated at full power until the pressure in the pot reaches 30KPA, the pressure maintaining stage is carried out.

As shown in fig. 3 to 5, in the present embodiment, the pressure limiting valve assembly 40 includes a pressure limiting valve body 41 and a weight 42. The cooking appliance further comprises a push structure 50 and a drive structure 90. The pushing structure 50 is disposed below the pressure limiting valve body 41 and the weight 42, and the pushing structure 50 includes a first pushing portion 51 engaged with the pressure limiting valve body 41 and a second pushing portion 52 engaged with the weight 42. The driving structure 90 drives the pushing structure 50 to move upward, wherein when the first pushing part is not matched with the pressure limiting valve body and the second pushing part is not matched with the counterweight block, the pressure limiting valve body and the counterweight block jointly act on the exhaust channel and apply a second exhaust pressure to the exhaust channel. When the pushing structure 50 moves upward, the second pushing portion 52 pushes the weight block 42 and the first pushing portion 51 is not engaged with the pressure limiting valve body 41, so that the pressure limiting valve body 41 acts on the exhaust passage 30 and applies a first exhaust pressure to the exhaust passage. In the exhaust stage, the pushing structure 50 continues to move upward, and the second pushing portion 52 pushes the weight block 42 while the first pushing portion 51 pushes the pressure limiting valve body 41, so as to exhaust the exhaust passage 30.

Specifically, as can be seen from fig. 5, the pushing structure 50 includes two concentrically arranged sleeve structures, and further, the upper end of the outer sleeve is provided with a rib. And the height of the top end of the convex rib is greater than that of the upper end of the inner sleeve. The ribs on the outer sleeve form the second push top 52 and the top end of the inner sleeve forms the first push top 51. When the driving structure 90 does not drive the pushing structure 50 to move upward, the first pushing top portion 51 is not engaged with the pressure limiting valve body 41, and the second pushing top portion 52 is not engaged with the pressure limiting valve body counterweight 42. At this time, the weight of the pressure limiting valve body 41 and the weight of the counter weight 42 act together on the exhaust passage 30, and at this time, a larger pressure, that is, a second exhaust pressure is applied to the exhaust passage 30. When the driving structure 90 drives the pushing structure 50 to move upward for a certain distance, the second pushing top portion 52 is engaged with the weight block 42 and pushes up the weight block 42. But the first ejector part 51 is not engaged with the pressure limiting valve body 41. At this time, only the weight of the valve body 41 acts on the exhaust passage 30, and a smaller exhaust pressure, i.e., a first exhaust pressure, is applied to the exhaust passage 30. When the exhaust is needed, the driving structure 90 makes the pushing structure 50 continue to move upward, at this time, the second pushing top portion 52 is matched with the counterweight block 42 and pushes up the counterweight block 42, and at the same time, the first pushing top portion 51 is matched with the pressure limiting valve body 41 and pushes up the pressure limiting valve body 41. At this time, the pressure limiting valve body 41 and the weight 42 do not act on the exhaust passage 30, and the exhaust passage 30 is in an exhaust state.

Preferably, the exhaust passage 30 is an exhaust pipe.

Preferably, the cooking appliance is an electric pressure cooker.
