The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A cooking appliance 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 14. Wherein the direction of the arrows in fig. 6-8 indicate the direction of the hot air flow inside the cooking chamber 21.

As shown in fig. 1-8, the cooking device 100 according to the present invention comprises a pot body 1, a pot cover 3 and an exhaust valve 4, the pot cover 3 is covered on the top of the pot body 1 and defines a cooking cavity 21 between the pot body 1, and the cooking device 100 can cook food materials put into the cooking cavity 21.

Be equipped with first seal structure 22 between the pot body 1 and pot cover 3, can improve sealed effect between the pot body 1 and pot cover 3 through setting up first seal structure 22, can prevent that cooking utensil 100 from going on the in-process of culinary art to eating the material, the steam in the culinary art chamber 21 flows out between the pot body 1 and pot cover 3. The hot air in the cooking cavity 21 is reserved in the cooking cavity 21, so that the aroma in the hot air can be fully blended into the food materials, the cooked food materials can be more delicious, and the cooking effect of the food materials is better.

The cooker cover 3 is provided with a valve mounting part 31, a valve mounting hole 32 penetrating through the valve mounting part 31 is arranged in the valve mounting part 31, the exhaust valve 4 is arranged on the valve mounting part 31 and is constructed to conduct the cooking cavity 21 and the external environment when the pressure in the cooking cavity 21 is greater than a preset value, and a second sealing structure 5 is arranged between the exhaust valve 4 and the valve mounting part 31.

That is to say, pot cover 3 is last to have valve mounting hole 32, in the culinary art process, the steam that produces in the culinary art chamber 21 can be discharged from valve mounting hole 32, discharge valve 4 can cooperate with valve mounting hole 32 in order to shutoff valve mounting hole 32, can improve the sealed effect between discharge valve 4 and the valve mounting hole 32 through setting up second seal structure 5, make the effect of discharge valve 4 shutoff valve mounting hole 32 better, and simultaneously, the second sealing member is established between discharge valve 4 and valve mounting hole 32, still can make the assembly between discharge valve 4 and the valve mounting hole 32 firmer, can prevent that discharge valve 4 from droing from the valve mounting hole 32. In addition, during the cooking process, the pressure of the gas in the cooking cavity 21 is gradually increased, when the pressure of the gas in the cooking cavity 21 is greater than a preset value, the exhaust valve 4 can be opened, and after the exhaust valve 4 is opened, the hot gas in the cooking cavity 21 can be exhausted to the external environment from the exhaust valve 4, so that the pressure of the gas in the cooking cavity 21 can be reduced, and the phenomenon that the cooking appliance 100 is damaged due to the fact that the pressure of the gas in the cooking cavity 21 is too high is prevented.

Wherein, the preset value may refer to a condition that the exhaust valve 4 is opened when the pressure of the gas in the cooking cavity 21 reaches a certain degree. For example, the preset value may be set by an electronic system, the cooking chamber 21 has a sensor for measuring the air pressure, and when the air pressure in the cooking chamber 21 is greater than a preset value in the system, the exhaust valve 4 may be opened, and the hot air in the cooking chamber 21 may be exhausted from the exhaust valve 4 to the external environment. The preset value may also be the maximum pressure value that the exhaust valve 4 can bear, and when the pressure in the cooking cavity 21 reaches a certain level, the pressure in the cooking cavity 21 may push the exhaust valve 4 open, so that the hot air in the cooking cavity 21 is exhausted to the external environment through the exhaust valve 4. The preset value can, of course, also be set by other methods, which are not limited herein,

therefore, according to the utility model discloses a cooking utensil 100 through set up first seal structure 22 between pot body 1 and pot cover 3, can make the steam in the culinary art chamber 21 be difficult to flow out from between pot body 1 and the pot cover 3 to be favorable to cooking utensil 100 to the culinary art effect of food, make the food that cooking utensil 100 cooks out more delicious. By arranging the exhaust valve 4, the valve mounting hole 32 can be opened or closed, specifically, when the gas pressure in the cooking cavity 21 is greater than a preset value, the exhaust valve 4 is opened, hot gas in the cooking cavity 21 can be exhausted from the exhaust valve 4, the phenomenon that the cooking appliance 100 is damaged or dangerous hidden dangers are prevented due to the fact that the gas pressure in the cooking cavity 21 is too large can be prevented, and reliability is high. When the gas pressure in the cooking cavity 21 is smaller than the preset value, the exhaust valve 4 can block the valve mounting hole 32, so that the hot gas in the cooking cavity 21 can be prevented from flowing out to influence the cooking effect of the cooking appliance 100 on food.

Alternatively, as shown in fig. 1, the valve mounting portion 31 may protrude upward from the surface of the pot cover 3, whereby the extension length of the valve mounting hole 32 in the up-down direction may be increased, so that the engagement of the discharge valve 4 with the valve mounting hole 32 may be facilitated.

In some embodiments of the present invention, the first sealing structure 22 includes a sealing groove 221 and a sealing flange 222, the sealing groove 221 is formed on the pot body 1, the top of the sealing groove 221 is open, the sealing flange 222 is formed on the pot cover 3, and the sealing flange 222 can be accommodated in the sealing groove 221. That is, the sealing flange 222 may cooperate with the sealing groove 221 to close a fitting gap between the pot body 1 and the lid 3, so that hot air in the cooking cavity 21 may be prevented from flowing out from the fitting gap between the pot body 1 and the lid 3. In some examples, after the sealing flange 222 is engaged with the sealing groove 221, the lower side surface, the inner side surface, and the outer side surface of the sealing flange 222 may be abutted against the inner wall surface of the sealing groove 221, so that the sealing flange 222 and the sealing groove 221 have a better sealing effect.
