[0038] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0039] Please see Figures 1 to 5 This application provides an air supply system 100, including an air guide assembly 10, an air guide frame 20, and an air supply fan 30.

[0040] The air guide assembly 10 includes a first air guide plate 11 and a second air guide plate 12 arranged opposite to each other. An air inlet 13 and an air guide cavity 14 are formed between the first air guide plate 11 and the second air guide plate 12 and are connected in sequence. The second air guide plate 12 is provided with a first connecting port 121 that connects to the air guide cavity 14. The air guide frame 20 has an air guide channel 21 and is located on the side of the second air guide plate 12 away from the first air guide plate 11. The first end 22 of the air guide frame 20 is provided corresponding to the first connecting port 121, and the second end 23 faces the electronic component 300. The air supply fan 30 is installed in the first connecting port 121 or the air guide channel 21 to guide the airflow flowing from the air inlet 13 to the air guide channel 21 to achieve heat dissipation of the electronic component 300.

[0041] The aforementioned air supply system 100 forms an air inlet 13 and an air guide cavity 14 by setting a first air guide plate 11 and a second air guide plate 12, so that airflow can flow in from the air inlet 13 and flow into the air guide cavity 14. Since the air supply fan 30 is located at the first connecting port 121 of the second air guide plate 12, it can drive the airflow into the air guide frame 20, so as to dissipate heat from the electronic component 300 located at the second end 23 of the air guide frame 20, thereby ensuring the service life of the electronic component 300.

[0042] In this embodiment, the electronic component 300 can be a camera, a control circuit board, or a microwave generator, etc. When the air supply system 100 is applied to the cooking device 200, such as a microwave oven, oven, or steam oven, the food will generate heat during the cooking process. Therefore, the air supply system 100 needs to be installed in the cooking device 200 to dissipate heat from the electronic components 300 such as the camera, control circuit board, or microwave generator installed in the cooking device 200, thereby ensuring the service life of the electronic components.

[0043] Further, please refer to Figure 3In order to prevent excessive heat from radiating towards the electronic component 300 during the cooking process, the second air guide plate 12 is provided with a frame 123 surrounding the second end 23 of the air guide frame 20. The frame 123 can block the heat from the surrounding area from being transferred to the electronic component 300, thereby further achieving the protection effect of the electronic component 300.

[0044] Please see Figure 1 and Figure 3 In one embodiment of this utility model, in order to better achieve the heat dissipation effect of the electronic component 300, an air outlet 15 is formed between the first air guide plate 11 and the second air guide plate 12, and the air outlet 15 is connected to the air guide cavity 14; the second air guide plate 12 is provided with a second connecting port 122 that connects to the air guide cavity 14, and the second end 23 of the air guide frame 20 is provided with a mounting groove 28 that connects to the second connecting port 122. The mounting groove 28 is used to install the electronic component 300. The second connecting port 122, the air guide cavity 14 and the air outlet 15 are interconnected. In this way, when the airflow flows in from the air inlet 13, it can not only flow out from the direction of the air guide frame 20 to flow directly to the electronic component 300, but also flow along the surface of the second air guide plate 12 to remove the heat from the upper surface of the electronic component 300. Thus, the electronic component 300 is cooled from two directions, achieving a more complete heat dissipation effect.

[0045] During installation, the first air guide plate 11 and the second air guide plate 12 can be first positioned and connected by plugging, and then assembled by bolts to ensure the stability of the connection.

[0046] Furthermore, in order to ensure the air intake volume, the first air guide plate 11 includes an arched area 111 and a flat area 112, and the second air guide plate 12 is flat. The arched area 111 corresponds to the air inlet 13. In this way, by setting the arched area 111, the air inlet 13 can have a larger opening, thereby ensuring the air intake volume.

[0047] Please see Figure 3 When the air supply system 100 is installed on the cooking device 200, the second air guide plate 12 is provided with a plurality of connecting posts 124 on the side opposite to the first air guide plate 11. The connecting posts 124 are connected to the external structure. For example, the external structure can be set as a heat insulation plate in the cooking device 200. The heat insulation plate is located above the cooking cavity and can isolate the heat in the cooking cavity, minimize the transfer to the electronic components 300, and ensure the service life of the electronic components 300.

[0048] Understandably, when setting up the connecting posts 124, multiple connecting posts 124 are set separately, so that there are multiple connection points with the heat insulation board, ensuring the stability of the connection.

[0049] Furthermore, since the second air guide plate 12 is a plate-shaped structure with a certain coverage area, in order to ensure the structural strength of the second air guide plate 12, a plurality of reinforcing ribs 125 are provided on the side of the second air guide plate 12 away from the first air guide plate 11. The reinforcing ribs 125 are connected to the connecting column 124. For example, a plurality of reinforcing ribs 125 can be arranged along the circumference of the connecting column 124. Thus, by setting the reinforcing ribs 125, the structural strength of the second air guide plate 12 is ensured, the probability of deformation is reduced, and the structural strength of the entire air guide assembly 10 is also ensured.

[0050] Understandably, since the first air guide plate 11 also has a certain coverage area, a reinforcing structure can be provided on the side of the first air guide plate 11 away from the second air guide plate 12 to prevent the first air guide plate 11 from collapsing. For example, the reinforcing structure can be configured to include multiple parallel ribs, or it can be configured to include sequentially intersecting ribs; there is no limitation here.

[0051] Furthermore, a support rib can be provided on the side of the second air guide plate 12 facing the first air guide plate 11. The support rib is supported on the inner surface of the first air guide plate 11. At the same time, the support rib can be set along the airflow direction to avoid interfering with the airflow. In this way, by setting the support rib, the first air guide plate 11 and the second air guide plate 12 can be in a structurally stable state after installation.

[0052] Please see Figure 3 and Figure 4 The diagram shows the structure of the air guide frame 20 of this utility model. The air guide frame 20 includes an installation section 24 and an air guide section 25. The installation section 24 corresponds to the second end 23, and the air guide section 25 corresponds to the first end 22. By setting the air guide frame 20 to include two sections, each section can be configured with its own structure.

[0053] Furthermore, the mounting section 24 and the air guide section 25 are set at an angle, so that the second end 23 with the angle can be adapted to the mounting position of the electronic component 300 without adjusting the mounting position of the electronic component 300, or the air guide frame 20 with the angle can avoid other mounting components, thereby achieving compact installation between components.

[0054] Specifically, please refer to Figure 4In this embodiment, the electronic component 300 is configured as an imaging device, and the entire air supply system 100 is positioned above the cooking cavity so that the imaging device can image the food located below. Compared to positioning the imaging device on the left, right, or rear side of the cooking cavity, this provides a wider shooting range and avoids blind spots. When the air supply system 100 is applied to a microwave oven with an imaging device, microwaves need to be introduced into the cooking cavity. Therefore, the imaging device needs to avoid the microwave inlet. In this case, the structure of the air guide 20 needs to correspond to the installation position of the imaging device. Therefore, the air guide 20 is configured to include an angled mounting section 24 and an air guide section 25, which also allows for the compact installation of other components.

[0055] Furthermore, since the microwave inlet is located at the center of the cooking cavity, the imaging device is positioned closer to the center of the cooking cavity, thus the mounting section 24 is positioned close to the center of the second air guide plate 12.

[0056] In order to accommodate the mutual installation of components, the width of the air guide channel 21 gradually decreases from the second end 23 to the first end 22, that is, the mounting section 24 has a larger size to accommodate the installation of the imaging device. At the same time, the size of the air guide channel 21 formed by the air guide section 25 is set to gradually decrease from the second end 23 to the first end 22, so that the end where the air supply fan 30 is installed has a smaller size, and a smaller size air supply fan 30 can be installed. In this way, the smaller size air supply fan 30 can be adapted to the size of other components installed above the cooking cavity, making full use of the small installation space and achieving compact installation between components.

[0057] Please refer to Figure 3 and Figure 5 Since the mounting section 24 in this embodiment is used to mount the imaging device, in order to capture images of the food located below, the imaging device has an angle θ relative to the horizontal plane. Furthermore, to ensure stable mounting of the imaging device, the air guide frame 20 has a support surface 26 for supporting the imaging device. The tilt angle of the support surface 26 relative to the horizontal plane is the same as the tilt angle of the imaging device relative to the horizontal plane, thus supporting the camera of the imaging device and preventing it from being suspended in mid-air. Simultaneously, the imaging surface 301 of the imaging device is set at an angle to the horizontal plane. The imaging device is used to image the food inside the cooking cavity of the cooking device. Therefore, setting the imaging surface 301 of the imaging device at an angle to the horizontal plane ensures the imaging range of the food. It is understood that the support surface 26 is provided with a light hole 27 to enable the imaging device to achieve the imaging effect. Specifically, the side of the mounting section 24 facing away from the second air guide plate 12 is the support surface 26.

[0058] When an air inlet 13 and an air outlet 15 are formed between the first air guide plate 11 and the second air guide plate 12, the air inlet 13 is formed by the first air guide plate 11 and the second air guide plate 12 surrounding each other, and the air outlet 15 is formed solely by the second air guide plate 12.

[0059] Specifically, please refer to Figure 1 and Figure 3 The end plate of the second air guide plate 12 is formed into a plurality of air outlet groups 16. Each air outlet group 16 includes a plurality of air outlets 15 arranged in parallel. The second air guide plate 12 has a groove 126 on the side away from the first air guide plate 11. The groove 126 is recessed towards the first air guide plate 11. A groove 126 is provided between each two adjacent air outlet groups 16. The groove 126 is provided to facilitate the insertion of a clamp into the groove 126 to fix the second air guide plate 12, thereby facilitating the formation of the structure of the second air guide plate 12. Since the groove 126 is provided between each two adjacent air outlet groups 16, it avoids interference with the formation of the air outlets 15.

[0060] Each air outlet group 16 may include two, three or more air outlets 15, which is not limited here.

[0061] The aforementioned air supply system 100, by forming an air outlet 15 between the first air guide plate 11 and the second air guide plate 12, allows airflow not only to flow from the air guide frame 20 to the electronic component 300 and then out, but also to flow out from the air outlet 15 formed between the first air guide plate 11 and the second air guide plate 12. The airflow from both parts dissipates heat from the electronic component 300, thus improving the heat dissipation effect. By setting the air guide frame 20 to include an angled mounting section 24 and an air guide section 25, it can be compactly installed with other components within the cooking device 200.

[0062] Please see Figures 6 to 8 In another embodiment of the present invention, a cooking device 200 is provided, including a shell 40 and an inner liner 50 disposed inside the shell 40. The inner liner 50 is provided with a cooking chamber 51. The shell 40 is provided with an air inlet 41 and a heat dissipation vent 42. The cooking device 200 also includes the aforementioned air supply system 100.

[0063] The air supply system 100 is located inside the outer shell 60 and beside the inner liner 70. For example, it can be located on the left, right, upper or lower side of the inner liner 70, and can achieve the effect of taking pictures of the food in the cooking chamber 51.

[0064] Preferably, in this embodiment, the air supply system 100 is located above the inner liner 70, so that the imaging device can image the food located below, thereby ensuring the imaging range and capturing the cooking state of the food in real time, thus ensuring the cooking effect.

[0065] The cooking device 200 described above, through the air supply system 100, can introduce airflow from the air inlet 41 and gather it into the air guide assembly 10. The airflow from the air guide assembly 10 to the air guide frame 20 can dissipate heat from the electronic components 300 installed at one end of the air guide frame 20, thereby ensuring the service life of the electrical components.

[0066] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
