As shown in fig. 1 and 2, the cooking appliance of the present embodiment includes a pot body 10, a pot cover 20, and an exhaust gas control device. Wherein, the pot body 10 is provided with liquid, and the liquid top is provided with the steaming grid, and the steaming grid is used for holding the food of being cooked, and pot cover 20 sets up on the pot body 10, is provided with the exhaust structure 30 with cooking space intercommunication on the pot cover 20. The exhaust control device is matched with the exhaust structure 30 and controls the exhaust state of the exhaust structure 30, when the temperature of the liquid in the pot body 10 reaches the preset temperature after the cooking utensil begins to cook, the exhaust control device controls the exhaust structure 30 to exhaust, and the liquid is continuously heated and continuously boiled, wherein the preset temperature is smaller than the boiling temperature of the liquid.

By applying the technical scheme of the embodiment, after the cooking utensil starts to cook, the liquid is heated to the first preset temperature, and the liquid is not boiled at the moment. The control device controls the exhaust structure 30 to exhaust, and at this time, the interior of the pan body 10 is communicated with the outside, so that the interior of the pan body 10 cannot generate pressure. Heating of the liquid continues and the liquid boils and a large amount of vapor is generated. The structure enables food to be cooked in a pressureless environment, and a large amount of steam is generated in the pot body, so that the steaming and cooking effects of the food are achieved. Meanwhile, the cooking mode also enables the steaming and cooking effect to be better. Therefore, the technical scheme of the embodiment solves the problem that the steaming function and the cooking effect of the electric pressure cooker in the prior art are poor.

The above-mentioned steaming lattice refers to a plate-shaped cooking tool, the steaming lattice is circular, and a plurality of through holes are formed in the steaming lattice to allow steam to pass through. The food to be steamed is placed on the steaming lattice. The food to be steamed is usually steamed bread, steamed stuffed bun, or meat such as seafood. Steaming and cooking mainly uses high-temperature steam to steam foods.

Specifically, in the technical solution of the present embodiment, the preset temperature is in the range of 85 degrees to 95 degrees. Specifically, the liquid described above is typically water. The boiling temperature of water is about 100 degrees. Thus in this embodiment, when the cooking operation is started, the water is first heated to a temperature in the range of 85 to 95 degrees. At this time, the water has not boiled, but bubbles have been generated, and there is a tendency for pressure to be generated in the pot 10. At this time, if no exhaust is performed, the cold air rod in the pot body 10 will be jacked up, so that the interior of the pot body 10 is quickly pressed up, and the cooking effect of steaming and cooking is seriously affected. Thus, in the present embodiment, when the water is heated to 85 to 95 degrees, the exhaust control means controls the exhaust structure 30 to exhaust air and communicates the inside and outside of the pot 10. At this time, the pressure of the pan body 10 is reduced, and the cold air bar cannot be jacked up, so that the inside of the pan body 10 cannot be pressurized. The food is steamed and cooked under the pressureless state, so that the delicious taste and the original flavor of the food are ensured, and the cooking effect of the steaming function is greatly improved.

As shown in fig. 1, in the technical solution of the present embodiment, during the continuous boiling process of the liquid, the exhaust control device controls the exhaust structure 30 to continuously exhaust. Specifically, when the water reaches 100 degrees, the water begins to boil and continues to generate a significant amount of steam. At this time, the exhaust control device controls the exhaust structure 30 to exhaust and continuously boil water, thereby continuously generating steam. The cooking process ensures that the food has sufficient moisture and saturated humidity. The steamed food is tender and soft in taste.

As shown in fig. 1 and 2, in the technical solution of the present embodiment, the exhaust structure 30 includes an exhaust pipe and a pressure limiting valve disposed on the exhaust pipe. Specifically, one end of the exhaust pipe is downwardly communicated with the cooking space in the pot body 10, and the other end is upwardly communicated with the outside. The pressure limiting valve is sleeved on the exhaust pipe. The pressure limiting valve is preferably a gravity pressure limiting valve.

In the technical solution of the present embodiment, the pressure limiting valve is preferably a gravity pressure limiting valve, and the cooking appliance further includes an exhaust ejection structure, where the exhaust ejection structure cooperates with the pressure limiting valve to control an exhaust state of the exhaust pipe. Specifically, before the water in the pan body 10 is heated to the boiling point temperature. The pressure generated in the pot 10 is insufficient to overcome the gravity of the pressure limiting valve itself, so that an auxiliary structure is required to push the pressure limiting valve. Specifically, a temperature sensor may be disposed on the pot body 10 or on the pot cover 20, and both the temperature sensor and the exhaust ejection structure are connected with the exhaust control device. When the temperature sensor detects that the temperature of water reaches the preset temperature, the temperature sensor transmits a signal to the exhaust control device, and the exhaust control device controls the exhaust ejection structure to push the pressure limiting valve upwards, so that the exhaust pipe is exhausted.

Preferably, the exhaust ejector structure is a solenoid valve. Further, since the exhaust pipe extends generally in a vertical direction, and since the space within the lid 20 is limited, the solenoid valve is generally horizontally placed. An intermediate transmission, such as a lever, a rotary lever or a plunger, can therefore also be arranged between the solenoid valve and the pressure limiting valve. The above structures are all conventional mechanical transmission structures, and are not described herein.

As shown in fig. 1 and 2, in the technical solution of the present embodiment, the pot cover 20 includes an inner liner 21 and a face cover 22 disposed on the inner liner 21, and the exhaust structure 30 is disposed on the inner liner 21 and protrudes upward out of the face cover 22. Tool with

As shown in fig. 2, in the technical solution of this embodiment, a pot body 10 includes an outer pot 11 and an inner pot 12 disposed in the outer pot 11, a steaming lattice is disposed in the inner pot 12, and a positioning structure matched with the steaming lattice is disposed on an inner wall of the inner pot 12. Specifically, the outer pan 11 includes a housing, a middle plate provided on an upper side of the housing, and a heat-insulating cover provided on a lower side of the middle plate. The inner pot 12 is accommodated in a heat-retaining cover. When the pot cover 20 is covered on the pot body 10, a cooking space is enclosed between the pot cover 20 and the pot body. The above-mentioned steaming lattice is provided in the inner pan 12, and the steaming lattice is spaced apart from the bottom wall of the inner pan so as to hold water. Therefore, in this example, the inner wall of the inner pot 12 is provided with a positioning structure, and the positioning structure can fix the steaming lattice at the middle position of the inner pot 12. The positioning structure may be a convex structure or a concave structure. And preferably, the above-described convex structures and concave structures may be annular convex and annular concave.

Preferably, the cooking appliance in the present embodiment is an electric pressure cooker.

The application also provides a control method of the cooking utensil, wherein the cooking utensil comprises a pot body 10, a pot cover 20 and an exhaust control device. Wherein, the pot body is internally provided with liquid, and the liquid top is provided with the steaming grid, and the steaming grid is used for holding the food of being cooked.
