[0028] When performing air frying, the existing air fryer oven needs to use a fan to blow air into the cavity assembly so that the heat of the heating element is evenly dispersed in the cavity assembly. In addition, in order to make the outside air blow evenly into the cavity assembly, multiple air inlets are generally provided on the air supply side of the cavity assembly. However, in actual use, there are differences in parameters such as air volume and wind speed of each air inlet, which will lead to uneven temperature distribution in the cavity assembly, which is easy to cause partial burn of food.

[0029] To this end, the embodiments of the present application provide an air guide structure and an air fryer oven to improve the problem of existing air fryers that food is easily partially burnt during air frying.

[0030] In order to make the objectives, technical solutions and advantages of the present application more clear, they are described in detail below with reference to specific drawings and embodiments.

[0031] refer to Figure 1 , an embodiment of the present application provides an air fryer oven 1.

[0032] refer to Figure 2 The air fryer oven 1 provided in the embodiment of the present application includes a shell 10, a cavity assembly 20, a frying net 30, a panel assembly 40, an oven door assembly 50 and an air supply assembly 60.

[0033] refer to Figure 2 The housing 10 is a U-shaped plate structure, which is used to be mounted outside the cavity assembly 20 and cover the top surface and side surfaces of the cavity assembly 20. The housing 10 is provided with an air inlet 11.

[0034] refer to Figure 3 The cavity assembly 20 includes a U-shaped plate 21, a bottom plate 22, a back plate 23 and heating tubes 24 and 25. The U-shaped plate 21 opens downward and is fixedly connected to the bottom plate 22, and an air inlet is provided on the side wall of the U-shaped plate 21. The back plate 23 is located at the back of the U-shaped plate 21 and the bottom plate 22, and the back plate 23 is fixedly connected to the U-shaped plate 21 and the bottom plate 22 to form a baking cavity with the cavity opening facing forward. The heating tube is arranged in the baking cavity for electrically heating to achieve baking. In addition, the cavity assembly 20 may further include a temperature sensor 26, which is arranged on the side wall of the U-shaped plate 21 to detect the baking temperature.

[0035] refer to Figure 2 and Figure 7 The frying net 30 is arranged in the baking cavity for placing the food to be cooked. Specifically, there should be a gap between the frying net 30 and the bottom of the baking cavity. In this way, the bottom of the food can be baked during the baking process.

[0036] refer to Figure 1 and Figure 2The panel assembly 40 is arranged at the cavity opening of the cavity assembly 20 and is connected and fixed to the housing 10. The panel assembly 40 is provided with a window 41 and a control panel 42 located on one side of the window 41. The window 41 is opposite to the cavity opening of the cavity assembly 20 and is connected to the baking cavity. The control panel 42 is staggered with the cavity opening, and the control panel 42 can be used to control parameters such as the heating power and heating time of the heating tube.

[0037] refer to Figure 1 and Figure 2 The oven door assembly 50 is disposed in the window 41 of the panel assembly 40. The oven door assembly 50 can rotate relative to the panel assembly 40 and has a first state of closing the window 41 and a second state of opening the window 41. Specifically, when the oven door assembly 50 is in the second state, the food to be cooked can be put into the baking cavity, or the cooked food can be taken out of the baking cavity. In addition, a handle can be provided on the oven door assembly 50 to facilitate the opening and closing of the oven door assembly 50.

[0038] refer to Figure 2 and Figure 7 The air supply assembly 60 includes a fan 61, which is located on the side of the U-shaped plate 21 and between the U-shaped plate 21 and the outer shell 10. The fan 61 is used to inhale external air from the air inlet 11 of the outer shell 10 and send air into the baking cavity from the air inlet of the side wall of the U-shaped plate 21, so that the heat of the heating tube can be evenly distributed in the baking cavity.

[0039] refer to Figure 3 and Figure 7 In some embodiments, the heating tube may include a first heating tube 24 and a second heating tube 25, wherein the first heating tube 24 is located above the frying net 30, and the second heating tube 25 is located below the frying net 30. In this way, the upper and lower sides of the food can be heated simultaneously, which is beneficial to improving the heating efficiency and shortening the cooking time.

[0040] It should be understood that there can be multiple first heating tubes 24 and multiple second heating tubes 25. In a specific implementation, the number of the first heating tubes 24 and the second heating tubes 25 can be selected according to actual conditions.

[0041] refer to Figure 4 and Figure 7 In some embodiments, the air inlet includes a first air inlet 211 and a second air inlet 212, the first air inlet 211 is located above the frying net 30, and the second air inlet 212 is located below the frying net 30. In this way, upper air supply and lower air supply can be achieved. Figure 7 As shown, the heat of the first heating tube 24 and the second heating tube 25 can be quickly dispersed in the baking chamber.

[0042] It should be understood that there may be a plurality of the first air inlet 211 and the second air inlet 212. In a specific implementation, the number of the first air inlet 211 and the second air inlet 212 may be selected according to actual conditions.

[0043] refer to Figure 4 In some embodiments, the side wall of the U-shaped plate 21 may also be provided with an air outlet 213 connected to the outside, and the air outlet 213 is connected to the outside. Specifically, the air outlet 213 may be provided through an air outlet 12 (such as Figure 2 When in use, the air outlet 213 can discharge the air (or hot air) in the baking cavity together with the water vapor generated by the food, so as to improve the dehydration efficiency of the food.

[0044] It should be understood that, in specific configuration, the number of air outlets 213 can be multiple, which can increase the speed of water vapor discharge. In addition, the air outlet 213 and the air inlet can be respectively arranged on the opposite side walls of the U-shaped plate 21, which can further accelerate the speed of water vapor discharge.

[0045] In some embodiments, an exhaust cavity connected to the air outlet 213 and the air outlet 12 may be formed between the housing 10 and the cavity assembly 20. In this way, the number of the air outlets 12 can be increased, which is beneficial to reduce the speed of water vapor discharge and reduce the impact on the outside during exhaust.

[0046] In a specific configuration, the exhaust cavity can be located on the side and top of the U-shaped plate 21. Therefore, in addition to exhausting from the side of the shell, exhaust can also be performed from the top of the shell and the back (back plate 23) of the cavity assembly 20. In other words, the back plate 23 of the cavity assembly 20 can also be provided with an air outlet 12.

[0047] refer to Figure 5 and Figure 6 In some embodiments, the air supply assembly 60 may further include an air guide structure 62, which is arranged between the U-shaped plate 21 and the fan 61, and is used to evenly distribute the outside air sent by the fan 61 to the first air inlet 211 and the second air inlet 212. In this way, the air volume of the first air inlet 211 and the second air inlet 212 can be kept consistent, so that the upper and lower temperatures of the frying net 30 can be kept consistent, avoiding the problem of partial burnt food due to uneven temperature.

[0048] refer to Figure 5 and Figure 6Optionally, the air guide structure 62 includes an air guide cover 621 and an air guide plate 622. The air guide cover 621 has a cavity that runs through the axial direction thereof. The air guide plate 622 is disposed in the cavity. The air guide plate 622 divides the cavity into a first air duct 623 and a second air duct 624 of the same diameter. For example, the first air duct 623 and the second air duct 624 are symmetrical about the center line of the air guide cover 621. In a specific setting, the first air duct 623 can be used to connect the fan 61 with the first air inlet 211, and the second air duct 624 can be used to connect the fan 61 with the second air inlet 212. In this way, the external air sent out by the fan 61 can be evenly distributed to the first air inlet 211 and the second air inlet 212.

[0049] It should be understood that the number of air ducts and air inlets of the air guide structure 62 is consistent. In a specific implementation, as the number of air inlets increases, the air guide structure 62 can be provided with air ducts that match the number of air inlets.

[0050] refer to Figure 6 Optionally, the first air duct 623 and the second air duct 624 are connected to each other at the air inlet side. That is, the air inlet of the first air duct 623 and the air inlet of the second air duct 624 are connected to each other.

[0051] refer to Figure 6 , optionally, the first air duct 623 and the second air duct 624 are gradually inclined outward from the direction of the fan 61 to the cavity assembly 20. That is, there is a gap between the air outlet of the first air duct 623 and the air outlet of the second air duct 624. Specifically, there is a gap between the air outlet of the first air duct 623 and the air outlet of the second air duct 624 that is equal to the distance between the first air inlet 211 and the second air inlet 212. In this way, it is convenient to connect the air outlet of the first air duct 623 and the air outlet of the second air duct 624 to the first air inlet 211 and the second air inlet 212, respectively.

[0052] In the specific setting, the air guide cover 621 can be trumpet-shaped, and the air guide plate 622 can be a V-shaped plate. Specifically, when the air guide plate 622 is located in the cavity of the air guide cover 621, a first air duct 623 and a second air duct 624 can be formed between the side wall of the air guide cover 621 and the side wall of the air guide plate 622. At the same time, the requirement that the first air duct 623 and the second air duct 624 gradually tilt outward from the direction of the fan 61 to the cavity assembly 20 can be met.

[0053] refer to Figure 6 Optionally, the diameters of the first air duct 623 and the second air duct 624 gradually decrease from the fan 61 to the cavity assembly 20. In this way, the air flow rate can be increased to speed up the discharge of water vapor.

[0054] In a specific configuration, the distance between the side wall of the V-shaped plate and the side wall of the air guide cover 621 can be gradually reduced from the direction of the fan 61 to the cavity assembly 20. In this way, the diameters of the first air duct 623 and the second air duct 624 can be gradually reduced from the direction of the fan 61 to the cavity assembly 20.

[0055] refer to Figure 5 Optionally, the wind guide cover 621 is provided with a first connection portion 625 and a second connection portion 626 at both ends of the axial direction thereof, the first connection portion 625 is used to connect with the cavity assembly 20, and the second connection portion 626 is used to connect with the fan 61. In this way, the wind guide cover 621 can be fixed, and the fan 61 can be indirectly fixed to the cavity assembly 20.

[0056] In specific configuration, the first connection portion 625 and the cavity assembly 20 as well as the second connection portion 626 and the fan 61 can be connected and fixed respectively by means of threaded connection.

[0057] It should be noted that the configuration of the above-mentioned air guide structure 62 is only an example provided in the embodiment of the present application and is not limited to the configuration discussed above.

[0058] According to the air guide structure 62 of the embodiment of the present application, the calibers of the first air duct 623 and the second air duct 624 are consistent, so that the air volume allocated to the first air inlet 211 and the second air inlet 212 are the same. In this way, it is possible to ensure uniform heat distribution in the baking cavity and avoid the problem of partial burnt food due to uneven heat.

[0059] One or more embodiments of this specification are intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of one or more embodiments of this specification should be included in the scope of protection of this application.

[0060] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
