For those skilled in the art, the specific meanings of the above terms can be understood according to the specific circumstances.

[0033] like Figure 1-Figure 5 As shown, an embodiment of the present invention provides a pressurized air intake mechanism, comprising a fan 41, a rotating shaft 42, and a pressurized air intake pipe 43. The fan 41 is located outside the inner pot 3 of the cooking device and is connected to one end of the rotating shaft 42. The rotating shaft 42 is passed through the side wall of the inner pot 3, and a stirring blade 44 is provided at one end of the rotating shaft 42 located inside the inner pot 3. A turbine 45 is also provided on the rotating shaft 42, and the turbine 45 is located between the stirring blade 44 and the side wall of the inner pot 3. One end of the pressurized air intake pipe 43 is connected to the side wall of the inner pot 3 at a position corresponding to the turbine 45.

[0034] like Figure 4-Figure 6As shown, when the pressurized air intake mechanism provided by the embodiment of the present invention is in operation, the stirring blade 44 rotates, and the airflow in the middle of the inner pot 3 of the cooking device is sucked in from the middle of the stirring blade 44 and diffused to the surroundings, and evenly spread in the inner pot 3, so as to achieve uniform heating of the food in the inner pot 3. The turbine 45 rotates with the stirring blade 44. On the side of the turbine facing the fan 41, area A is the air compression area, and area B is the air release area. The air flow direction is A→B. After the air in area A is compressed and transmitted to area B, low pressure will appear near area A, and the air enters the inner pot 3 (as shown in FIG. 1 ) through the pressurized air intake pipe 43. Figure 4 、 Figure 6 The turbine 45 is coaxially installed with the stirring blade 44 to share the fan 41, and there is no need to add a separate fan system, so that the structure of the entire system is simple, the manufacturing cost is low, and the assembly efficiency is high. At the end of cooking or after the end of cooking, a large amount of heat accumulates in the electrical component area at the top of the cooking device. If the heat is not discharged in time, it will have a negative impact on the service life of the electrical components. The pressurized air intake mechanism can extract hot air from the electrical component area and inject it into the inner pot 3, thereby accelerating the heat dissipation of the electrical component area and extending the service life of the electrical components.

[0035] In order to control the start and stop of the supercharged intake mechanism, refer to Figure 4 、 Figure 5 、 Figure 6 The end of the boost air intake pipe 43 is provided with a solenoid valve 46. If a large amount of air needs to be injected into the inner container 3 to discharge the steam and / or oil smoke inside, the solenoid valve 46 connected to the boost air intake pipe 43 is opened, and air enters the inner container 3 through the boost air intake pipe 43 (such as Figure 4 、 Figure 6 In the embodiment of the present invention, the air inlet pipe 43 is connected to the inner pot 3 and the air inlet pipe 44 is connected to the inner pot 3. ...

[0036] like Figure 1 、 Figure 2 、 Figure 6As shown, in one embodiment of the present invention, the sidewall of the inner container 3 protrudes outward to form a turbine chamber 31, within which the turbine 45 is located. The turbine chamber 31 is provided with a turbine air inlet on the outside, connected to an air inlet hood 32, which is laterally connected to the supercharged air inlet pipe 43. The turbine chamber 31 facilitates the turbine 45 to pressurize the inner container 3, while the air inlet hood 32 is used to guide air into the inner container 3. When the solenoid valve 46 is opened, the interior of the air inlet hood 32 is connected to the atmosphere. As the fan 41 operates, area A of the turbine 45 compresses air and transfers it to area B, which then transfers it into the inner container 3. This increases the air pressure within the inner container 3 and rapidly expel steam and fumes through the slow-pressure exhaust mechanism 5. After a period of operation, the solenoid valve 46 closes, significantly reducing the amount of fumes and steam remaining in the inner container 3. This prevents the user from being hit by fumes and / or steam when the door is opened, and allows for the rapid removal of odors from the inner container 3.

[0037] In order to prevent the mixing blade 44 and the rotating shaft 42, and the turbine 45 and the rotating shaft 42 from rotating relative to each other, thereby affecting the rotation of the mixing blade 44 and the turbine 45, as shown in FIG. Figure 7 As shown, in one embodiment of the present invention, the middle portion of the stirring blade 44 is provided with a first positioning hole 441, the middle portion of the turbine 45 is provided with a second positioning hole 451, and the rotating shaft 42 is provided with a first positioning protrusion 421 corresponding to the first positioning hole 441 and a second positioning protrusion 422 corresponding to the second positioning hole 451. In this embodiment, the cross section of the first positioning protrusion 421 is semicircular, and the cross section of the second positioning protrusion 422 is cross-shaped. Further, in order to limit the positions of both sides of the stirring blade 44 and the turbine 45 and prevent them from moving axially along the rotating shaft 42, the first positioning protrusion 421 is provided with a first limiting protrusion 423 at one end toward the second positioning protrusion 422, and a first positioning member 424 is provided at the other end. The cross-sectional shape of the first limiting protrusion 423 corresponds to the cross-sectional shape of the second positioning hole 451, so as to facilitate the installation of the turbine 45. The second positioning protrusion 422 has a second limiting protrusion 425 at one end thereof facing the fan 41, and a second positioning member 426 at the other end thereof. In this embodiment, the first positioning member 424 is a nut, and the second positioning member 426 is a C-shaped buckle.

[0038] like Figure 8 As shown, the present invention also provides a cooking device including the above-mentioned pressurized air intake mechanism. The cooking device can be an integrated stove, an integrated cooking center, a steamer, an oven, a steam oven, etc.

[0039] like Figure 9 、 Figure 10As shown, in one embodiment of the present invention, an air guide hood 33 is provided on the inner wall of the inner container 3. The air guide hood 33 covers the stirring blades 44 and the turbine 45, and the air guide hood 33 is provided with air guide holes 331. The area between the air guide hood 33 and the side wall of the inner container 3 is called a hot air chamber. The stirring blades 44 rotate in the hot air chamber, and in conjunction with the air guide holes 331 in various directions, the air flow can be guided to spread in the inner container 3 to uniformly form the temperature field.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
