Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0043] Please also refer to Figure 1 and Figure 2 , the air outlet structure provided in the embodiment of the present application is now described. The air outlet structure is installed on the cooking device, and the cooking device has a cooking cavity 10. The air outlet structure includes an air guide shell 100 and an air outlet cover 200. The air guide shell 100 is installed on the cooking device. The air guide shell 100 is provided with a first air guide hole 101, an air guide channel 102, and a second air guide hole 103 that are connected in sequence. The first air guide hole 101 is connected to the cooking cavity 10; the air outlet cover 200 is located on the side of the cooking device, and an air outlet 210 is provided on the side of the air outlet cover 200, and the air outlet 210 is connected to the second air guide hole 103. Figure 2 In the figure, the direction indicated by the black arrow is the flow direction of the hot air in the air guide shell 100 and the air outlet cover 200.

[0044] Compared with the prior art, the air outlet structure provided in the embodiment of the present application is provided with an air guide shell 100 and an air outlet cover 200. The hot air generated by the cooking cavity 10 can be transferred to the air outlet cover 200 through the first air guide hole 101, the air guide channel 102 and the second air guide hole 103 of the air guide shell 100; the side of the air outlet cover 200 is provided with an air outlet 210, which prevents the hot air from blowing directly upward onto the cabinet, prevents the cabinet from being in a high temperature environment, and improves the service life and safety of the cabinet.

[0045] In one embodiment of this application, please refer to Figure 1 and Figure 2 The air outlet structure further includes an air guide impeller 300 , which is disposed in the air guide channel 102 and is rotatably connected to the air guide housing 100 , and a rotation axis of the air guide impeller 300 coincides with an axis of the first air guide hole 101 .

[0046] In this embodiment, by providing the air guide impeller 300 , a traction force can be generated on the hot air flowing through the air guide channel 102 , thereby greatly improving the air outlet efficiency.

[0047] It is understandable that if the air guide impeller 300 is not provided, when the hot air comes out of the first air guide hole 101, it will easily hit the side wall of the air guide channel 102, forming a small vortex, thereby hindering the air outlet efficiency.

[0048] Furthermore, to enhance the durability and maintenance ease of the air outlet structure, the impeller 300 and its associated components feature an easily removable design. This allows users to easily clean or replace the impeller 300 without disassembling the entire cooking device, effectively extending the lifespan of the cooking device and enhancing the user experience.

[0049] In one embodiment of the present application, the guide impeller 300 includes a plurality of guide blades, and the angle between two adjacent guide blades ranges from 40° to 90°.

[0050] In this embodiment, the angle of the air guide blades is set between 40° and 90°, so that the shape and number of the air guide blades are limited to ensure that while the hot air is efficiently guided, the collision and vortex generation between the air and the blades during flow are minimized, thereby reducing noise.

[0051] In addition, the materials of the air guide shell 100 and the air outlet cover 200 are also selected to have good sound absorption performance, which further reduces the spread of noise.

[0052] In one embodiment of this application, please refer to Figure 3 and Figure 4 The air outlet 210 includes an air inlet 211, an air outlet channel 212 and an air outlet 213 which are connected in sequence; the air inlet 211 is connected to the second air guide hole 103; the air inlet 211 and the air outlet 213 are respectively located on two adjacent sides of the air outlet cover 200.

[0053] In this embodiment, the air inlet 211 and the air outlet 213 are respectively located on two adjacent sides of the air outlet cover 200, which can change the air outlet direction and prevent the hot air from blowing directly backwards onto the wall, thereby preventing the hot air from gathering around the cooking device.

[0054] In one embodiment of the present application, see Figure 3 , an air guide block 220 is provided in the air outlet channel 212, please refer to Figure 4 and Figure 5 The air guide block 220 has an air guide surface 221 , and the air guide surface 221 is inclined with respect to a vertical plane where the axis of the air inlet hole 211 is located.

[0055] In this embodiment, by providing the air guide block 220 , hot air can be guided from the air inlet 211 to the air outlet 213 , thereby improving the hot air outlet efficiency.

[0056] Specifically, the air guide block 220 can be set in the middle of the air outlet channel 212, and the two opposite sides of the air guide block 220 are provided with air guide surfaces 221. Correspondingly, the two opposite sides of the air outlet cover 200 are provided with air outlet holes 213. Air can be discharged from both sides of the air outlet cover 200, which greatly improves the air outlet efficiency.

[0057] In one embodiment of this application, please refer to Figure 4 and Figure 5 A partition 230 is further provided in the air outlet channel 212. The partition 230 is arranged in a horizontal direction, and the partition 230 divides the air outlet hole 213 into a plurality of air outlet eyes.

[0058] In this embodiment, by providing a partition 230 in the air outlet channel 212, the space of the air outlet channel 212 is further compressed. When the hot air is transferred to the air outlet cover 200, a certain air pressure can be generated, thereby making the air outlet smoother.

[0059] In one embodiment of the present application, the angle between the air guide surface 221 and the vertical plane where the axis of the air inlet hole 211 is located is in the range of 10°-38°.

[0060] In this embodiment, the included angle between the air guide surface 221 and the vertical plane where the axis of the air inlet hole 211 is located is set between 10° and 38°, and the hot air guiding effect is most obvious, and the hot air guiding effect gradually increases from 10° to 38°.

[0061] in, Figure 4 Schematic diagram showing that the included angle between the air guide surface 221 and the vertical plane where the axis of the air inlet hole 211 is located is 10°; Figure 5 This is a schematic diagram showing that the included angle between the air guide surface 221 and the vertical plane where the axis of the air inlet hole 211 is located is 38°.

[0062] See also Figure 6 An embodiment of the present application also provides a cooking device, including a shell 20 and the above-mentioned air outlet structure; a cooking cavity 10 is provided in the shell 20; an air guide shell 100 is installed on the top of the shell 20, and an air outlet cover 200 is installed on the side of the shell 20.

[0063] In this embodiment, the air outlet structure adopted by the cooking device includes an air guide shell 100 and an air outlet cover 200. The hot air generated by the cooking cavity 10 can be transferred to the air outlet cover 200 through the first air guide hole 101, the air guide channel 102 and the second air guide hole 103 of the air guide shell 100; an air outlet 210 is provided on the side of the air outlet cover 200, which prevents the hot air from blowing directly upward onto the cabinet, prevents the cabinet from being in a high temperature environment, and improves the service life and safety of the cabinet.

[0064] Specifically, threaded holes are provided on the air hood 200 and the housing 20, and the air hood 200 and the housing 20 are connected by screws, which improves the convenience of disassembly and assembly of the air hood 200. The air hood 200 is provided with positioning posts, and the housing 20 is provided with positioning holes. The positioning posts and positioning holes cooperate to achieve quick positioning and installation of the air hood 200.

[0065] In another embodiment of the present application, a sealing ring is further provided between the air outlet cover 200 and the outer shell 20 to improve the sealing of the structure and prevent hot air from leaking out of the gap between the air outlet cover 200 and the outer shell 20, thereby affecting the air outlet efficiency.

[0066] In one embodiment of the present application, the distance between the air outlet 210 and the outer wall of the housing 20 is greater than or equal to 10 mm.

[0067] In this embodiment, the distance between the air outlet 210 and the outer wall of the housing 20 is greater than or equal to 10 mm. When hot air flows out of the air outlet 210, it can be prevented from blowing onto the outer wall of the housing 20, thereby preventing heat generated by the hot air from accumulating on the outer wall of the housing 20, thereby increasing the service life of the cooking device.

[0068] See also Figure 6 An embodiment of the present application also provides a cooking device, comprising a plurality of the above-mentioned cooking devices, wherein the plurality of cooking devices are stacked in a vertical direction.

[0069] In this embodiment, by providing multiple cooking devices, multiple foods can be cooked simultaneously, thereby improving cooking efficiency.

[0070] As we all know, hot air rises. The principle is that the air temperature is high, the molecular movement speed is fast, and the distance between molecules is large, so the air density is small, that is, the air pressure is low, and the mass is small, so it will float above the air with large mass and high density.

[0071] In this embodiment, the hot air blown out by the air outlet device of the cooking device located at the lower layer will gather upward. In order to reduce the impact of the hot air on the outer shell 20 of the cooking device, the distance from the air outlet 210 of the cooking device located at the upper layer to the outer wall of the outer shell 20 is greater than the distance from the air outlet 210 of the cooking device located at the lower layer to the outer wall of the outer shell 20.

[0072] In this embodiment, the cooking equipment takes a double-layer vertical air fryer as an example. The distance between the air outlet 210 of the air fryer located on the upper layer and the outer wall of the shell 20 can be 18.7 mm, and the air outlet 210 of the upper air fryer is 19 mm away from the wall; the distance between the air outlet 210 of the air fryer located on the lower layer and the outer wall of the shell 20 can be 10 mm, and the air outlet 210 of the lower air fryer is 19 mm away from the wall.

[0073] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
