The grille element 40 is arranged at the air outlet 10. The grille element 40 includes a bracket 41 and a plurality of baffles 42 arranged on the bracket 41. The baffles 42 are arranged at intervals along the length direction of the grille element 40. The baffles 42 and the bracket 41 jointly define a guide channel 43. The baffles 42 include a first baffle 421 and a second baffle 422. At least one second baffle 422 is arranged between two adjacent first baffles 421. Along the air outlet direction of the guide channel 43, the length of the first baffle 421 is greater than the length of the second baffle 422.

[0040] In this way, the length of the first baffle 421 is greater than the length of the second baffle 422, and the first baffle 421 can increase the connection area with the bracket 41, thereby enhancing the structural strength of the grille element 40, and the second baffle 422 can reduce the distance of air flowing through the guide channel 43, thereby reducing the air circulation resistance, making the air outlet distribution uniform, and at the same time can improve the air outlet efficiency of the air outlet 10, thereby improving the heat dissipation efficiency of the cooking appliance 1000. In addition, at least one second baffle 422 is provided between two adjacent first baffles 421, which can improve the aesthetic appearance of the grille element 40, thereby improving the overall appearance of the cooking appliance 1000.

The cavity 20 can be a regular three-dimensional structure such as a rectangular parallelepiped or a cylindrical shape, or can be an irregular three-dimensional structure. An opening 21 is formed on one side of the cavity 20. When the opening 21 is opened, it is convenient for the user to take out and put food through the opening 21. When the opening 21 is closed, it is convenient for the cooking appliance 1000 to cook the food.

[0044] The exhaust assembly 30 can be installed on the top of the cavity 20. The exhaust assembly 30 includes a fan and an air guide cover. The fan is located on the rear side of the cavity 20. The air guide cover connects the fan and the air outlet 10. When the fan is started, it can draw air from the outside and discharge it into the air guide cover. The air guide cover guides the air from the fan to the air outlet 10, and the heat is discharged from the air outlet 10 together with the air.

The flush arrangement of the ends of the first barrier portion 421 and the second barrier portion 422 located upstream of the guide channel 43 can mean that the distance between the end of the barrier portion 42 located upstream of the guide channel 43 and the bracket 41 is equal.

[0053] In this way, the arc surface can guide the air to flow out of the guide channel 43, while reducing the flow resistance of the first end 44 to the air flowing out of the guide channel 43, thereby improving the air outlet efficiency of the air outlet 10 and further improving the heat dissipation efficiency of the cooking appliance 1000.

[0054] Specifically, the air can enter the guide channel 43 from the second end 45 and then be discharged from the first end 44. The barrier portion 42 may include a third end 46, which connects the first end 44 and the second end 45. The width of the connection between the third end 46 and the first end 44 may be consistent with the width of the connection between the third end 46 and the second end 45, or the width of the connection between the third end 46 and the first end 44 may be greater than the width of the connection between the third end 46 and the second end 45. The sizes of the first end 44, the second end 45 and the third end 46 may be set according to actual needs, and the spacing between two adjacent barrier portions 42 may be the distance between the third ends 46 of the two adjacent barrier portions 42.

[0055] See also Figure 7 In some embodiments, along the opposite direction of the air outlet direction of the guide channel 43, the blocking portion 42 has a tendency to converge toward the second end portion 45.

[0056] In this way, the second end 45 tends to converge to increase the area of ​​the guide channel 43, increase the air output of the air outlet 10, and reduce the flow resistance of the second end 45 to the air flowing out of the guide channel 43, thereby improving the air outlet efficiency of the air outlet 10 and further improving the heat dissipation efficiency of the cooking appliance 1000.

[0057] Specifically, the width of the second end 45 close to the third end 46 is greater than the width of the second end 45 away from the third end 46. The second end 45 may be an arcuate surface, or a triangular surface, a trapezoidal surface, or the like.
