[0036] See also Figures 2 to 8 The steam generating assembly provided in the embodiment of the present application is now described. The steam generating assembly of this embodiment is used in an air fryer, and the steam generating assembly includes:

[0037] The heating plate 1 is provided with a central hole 101 for air flow to pass through;

[0038] The steam generating structure is provided on the heating plate 1 . The steam generating structure is provided with a steam outlet 102 . The steam outlet 102 is staggered with the central hole 101 .

[0039] It is important to note that the heating plate 1 is a component of the air fryer itself. The heating plate 1 generates heat to heat the air, which circulates within the air fryer to heat and cook the food. The heating plate 1 has a central hole 101 for airflow, thereby forming a circulating airflow within the air fryer.

[0040] The steam generating structure is a key component in steam production. Positioned on the heating plate 1, it ensures sufficient heating of the steam generating structure. Water is supplied to the steam generating structure, enabling it to efficiently generate steam. A steam outlet 102 is provided on the steam generating structure. Steam generated by the steam generating structure is delivered to the interior of the air fryer through the outlet 102, regulating the humidity within the frying vat 5 and, in turn, the food's humidity, preventing excessive moisture loss from the food and improving its taste.

[0041] The central hole 101 of the heating plate 1 is used for the circulation of circulating airflow, and the steam outlet 102 of the steam generating structure is staggered with the central hole 101 of the heating plate 1 to avoid the airflow directly impacting the steam outlet 102 and causing the steam to spread everywhere, thereby ensuring that the steam generated by the steam outlet 102 can be evenly and stably diffused and contact with the food, achieving a better cooking effect.

[0042] In some embodiments of the present application, the steam generating structure and the heating plate 1 are configured as an integrally formed structure. The steam generating structure is provided on the heating plate 1, and the specific configuration method may be that the steam generating structure is connected to the heating plate 1 by welding, screw connection, clamping, etc. Although these methods can enable the heating plate 1 to heat the steam generating structure, the structure is relatively complex and the heat conduction is also limited. Therefore, in this embodiment, the steam generating structure and the heating plate 1 are configured as an integrally formed structure. That is, the steam generating structure and the heating plate 1 can be designed as an integral whole, and the steam generating structure and the heating plate 1 can be processed and formed together without having to be processed separately and then connected together. The steam generating structure and the heating plate 1 are integrally formed, which not only improves the efficiency of heat transfer from the heating plate 1 to the steam generating structure, but also simplifies the structure of the components, reduces manufacturing costs, and reduces the space occupied inside the air fryer.

[0043] Steam generating structures can take many forms, see Figure 2 refer to Figure 3 In some embodiments of the present application, the heating plate 1 includes a plate body 109 , and the steam generating structure includes a water supply channel 104 , which is disposed in the plate body 109 .

[0044] The tray body 109 is the foundation of the heating tray 1. In this embodiment, the tray body 109 not only houses the heating element but also houses the water channel 104 required for steam generation. To accommodate the water channel 104, the tray body 109 can be thickened to a thickness greater than the diameter of the water channel 104, allowing the water channel 104 to be located within it.

[0045] The water supply channel 104 can be a hole opened in the dish body 109 or a pipe embedded in the dish body 109. After the water supply channel 104 is provided, water can be introduced into the dish body 109 through the water supply channel 104 to ensure that the water can be fully heated. During the heating process, the water is converted into steam, which escapes from the steam outlet 102 and enters the air fryer to regulate the humidity inside the air fryer.

[0046] See also Figures 2 to 3 In some embodiments of the present application, the heating plate 1 includes a first surface and a second surface relative to each other, and a center hole 101 passes through the first surface and the second surface; the steam outlet 102 is located at one end of the water supply channel 104, and a water inlet 103 is provided at the other end of the water supply channel 104, the steam outlet 102 is located on the first surface, and the water inlet 103 is located at the edge of the heating plate 1.

[0047] The heating plate 1 includes a first surface and a second surface relative to each other. Since the heating plate 1 is usually arranged horizontally in the air fryer, these two surfaces are usually the upper surface and the lower surface of the heating plate 1. The central hole 101 runs through the first surface and the second surface, providing a channel for circulating airflow. One end of the water supply channel 104 is connected to the water inlet 103, and the other end is connected to the steam outlet 102. Moisture can smoothly enter the heating plate 1 through the water inlet 103, and is converted into steam during the heating process, and finally released into the air fryer through the steam outlet 102. The steam outlet 102 is located on the first surface, so that the steam outlet 102 can be staggered with the central hole 101. The water inlet 103 is located at the edge of the heating plate 1, which is convenient for access to an external water source.

[0048] When the air fryer begins operating, heating plate 1 rapidly heats up. Simultaneously, an appropriate amount of water is injected into water channel 104 through water inlet 103. Under the high temperature of heating plate 1, the water gradually transforms into steam within water channel 104. As the steam accumulates, it is eventually released into the air fryer through steam outlet 102, thereby regulating the humidity within the air fryer.

[0049] See also Figures 2 to 3 In some embodiments of the present application, the second surface is provided with heat dissipation fins 107, while the steam outlet 102 is located on the first surface, and the first surface and the second surface are two opposing surfaces. The heat dissipation fins 107 are generally located on the side of the heating plate 1 facing the air supply mechanism 4, so that the air delivered by the air supply mechanism 4 can fully contact the heat dissipation fins 107, thereby ensuring the efficiency of air heating. The steam outlet 102 is located on the first surface, that is, opposite the heat dissipation fins 107, which is the side facing the food. The steam outlet 102 is located on this side so that the steam outlet 102 can be directed toward the food, and the output steam can directly act on the food, thereby improving the efficiency and quality of humidity regulation.

[0050] See also Figures 4 and 5 In some embodiments of the present application, the steam generating structure includes a water trough 105 , which is arranged at the edge of the heating plate 1 , and the steam outlet 102 is an opening of the water trough 105 .

[0051] The steam-generating structure of this embodiment is a water channel 105, located at the edge of the heating plate 1. Its primary function is to store and transport water. During cooking, an appropriate amount of water can be injected into the heating plate 1 through the water channel 105. As the heating plate 1 heats, the water gradually heats within the water channel 105 and converts into steam. Because the water channel 105 is located at the edge of the heating plate 1, the generated steam avoids the high-speed airflow from the central hole 101 and diffuses more smoothly toward the food below.

[0052] The opening of the water trough 105 serves as the steam outlet 102. When the heated water in the water trough 105 is converted into steam, it can escape through the opening of the water trough 105. The design of the water trough 105 simplifies the steam generation and delivery structure, eliminating additional pipes and connecting components, thereby reducing failure rates and maintenance costs. Furthermore, the water trough 105 is easy to maintain and clean.

[0053] See also Figures 4 and 5 In some embodiments of the present application, the water delivery groove 105 is provided along the circumference of the heating plate 1. The water delivery groove 105 can be provided on one side edge or multiple sides of the heating plate 1. In this embodiment, the water delivery groove 105 is provided along the circumference of the heating plate 1, so that the water delivery groove 105 can generate steam uniformly around the circumference of the heating plate 1, thereby ensuring uniform steam flow inside the air fryer.

[0054] See also Figures 6 to 8 In some embodiments of the present application, the steam generating structure includes a water pipe 108, the steam outlet 102 is located at one end of the water pipe 108, and a water inlet 103 is provided at the other end of the water pipe 108, and the steam outlet 102 and the water inlet 103 are both located at the edge of the heating plate 1.

[0055] In this embodiment, the water pipe 108 is the core component of the steam generation structure, responsible for transporting water from the water inlet 103 to the steam outlet 102. During cooking, the user can inject an appropriate amount of water into the water pipe 108 through the water inlet 103. As the heating plate 1 heats, the water gradually heats up in the water pipe 108 and converts into steam. The steam is then released into the air fryer through the steam outlet 102, moistening the food.

[0056] One end of the water pipe 108 is the steam outlet 102, and the other end is the water inlet 103. The water inlet 103 and the steam outlet 102 are both located at the edge of the heating plate 1. On the one hand, it is convenient for the pipe connection of the water inlet 103. On the other hand, it can avoid the airflow of the center hole 101, and the slower airflow around the steam outlet 102 can directly drive the steam to flow downward to the food, ensuring the humidity regulation of the food.

[0057] See also Figures 6 to 8In some embodiments of the present application, a heating pipe 106 is provided on one side of the heating plate 1, and the water pipe 108 is located on the same side of the heating plate 1 as the heating pipe 106. The heating pipe 106 is the heating element of the heating plate 1, and is usually bent and arranged on one side of the heating plate 1. The heating pipe 106 and the water pipe 108 are located on the same side of the heating plate 1, so that the water in the water pipe 108 can be more easily exposed to the heat generated by the heating pipe 106, thereby accelerating the evaporation of water and the generation of steam. In addition, when arranging the water pipe 108, it can be arranged in an area not covered by the heating pipe 106, thereby avoiding interference between the arrangements of the heating pipe 106 and the water pipe 108. To save space, the water pipe 108 can also be set as a semicircular pipe, in which the surface of the heating plate 1 acts as the pipe wall on one side of the plane of the water pipe 108. This ensures that the water in the water pipe 108 is heated and converted into steam, and facilitates the integrated molding of the heating plate 1 and the water pipe 108.

[0058] Based on the above-mentioned steam generating assembly, the present application also provides an air fryer, which includes the above-mentioned steam generating assembly. Due to the presence of the steam generating assembly, the water in the steam generating structure can be converted into steam by utilizing the heat provided by the heating plate 1 while heating and cooking the food. The steam generating structure is arranged on the heating plate 1, which can ensure that the heating plate 1 fully heats the steam generating structure. After water is supplied to the steam generating structure, the steam generating structure can efficiently generate steam. A steam outlet 102 is provided on the steam generating structure. The steam converted by the steam generating structure is transported to the interior of the air fryer through the steam outlet 102, regulating the humidity in the frying barrel 5, and then regulating the humidity of the food, preventing the moisture in the food from being taken away too much, thereby improving the taste of the food. The steam generating structure can be integrally formed with the heating plate 1, which not only ensures the efficient transfer of heat from the heating plate 1 to the steam generating structure, but also simplifies the structure of the component, reduces manufacturing costs, and reduces the space occupied inside the air fryer.

[0059] See also Figure 1In some embodiments of the present application, the air fryer further comprises a water tank 2 and a water delivery mechanism 3, wherein the water tank 2 is connected to the water delivery mechanism 3, and the water delivery mechanism 3 is connected to the steam generating structure. The water tank 2 is used to store the water required by the steam generating structure and deliver it to the steam generating structure through the water delivery mechanism 3. The water delivery mechanism 3 is a bridge connecting the water tank 2 and the steam generating structure, and is responsible for delivering the water in the water tank 2 to the steam generating structure. The water delivery mechanism 3 generally comprises a water pump and corresponding pipes, and can also use gravity in conjunction with a valve to achieve water delivery. The amount of water flowing into the steam generating structure can be controlled by a water pump or a valve. While ensuring sufficient water supply, it can also prevent the flow rate from being too high, causing water to enter the fryer cavity without being vaporized. In addition, by adjusting the water delivery mechanism 3, the humidity in the air fryer can also be adjusted, allowing users to customize the taste of food due to humidity.

[0060] See also Figure 1 In some embodiments of the present application, an air fryer includes an air supply mechanism 4 and a frying tub 5. The air supply mechanism 4, heating plate 1, and frying tub 5 are arranged sequentially from top to bottom. The air supply mechanism 4 is typically located at the top of the air fryer and is responsible for evenly blowing hot air or steam into the frying tub 5. The air supply mechanism 4 may include components such as a fan, air ducts, and air outlets, which work together to circulate and evenly distribute the hot air. The air supply mechanism 4 allows the hot air or steam to quickly fill the frying tub 5, effectively exchanging heat with the food, thereby improving cooking efficiency and quality. The heating plate 1 is located between the air supply mechanism 4 and the frying tub 5 and is responsible for providing the heat required for cooking. During the cooking process, the heating plate 1 is heated by an electric current, transferring heat to the frying tub 5 and the food inside, thereby achieving the desired cooking effect. The frying tub 5 is responsible for containing the food and withstanding the high temperatures and pressures during the cooking process.

[0061] In an embodiment in which the steam generating structure includes a water supply channel 104 and the water supply channel 104 is disposed within the pan body 109, the first surface of the heating pan 1 is disposed toward the frying vat 5. Since the steam outlet 102 is located on the first surface, the steam outlet 102 can be disposed toward the frying vat 5. Steam overflowing from the steam outlet 102 can quickly and directly contact the food, thereby improving the efficiency of humidity regulation.

[0062] For the embodiment in which the steam generating structure includes a water delivery groove 105, the water delivery groove 105 of the steam generating assembly is arranged toward the air supply mechanism 4. This ensures that the water delivery groove 105 is arranged upwards, preventing the water therein from flowing out of the water delivery groove 105.

[0063] In embodiments where the steam generation structure includes a water pipe 108, the water pipe 108 of the steam generation assembly is located on the side of the heating plate 1 facing the air supply mechanism 4. This is because the heating pipe 106, serving as the heating element, is located on the side of the heating plate 1 facing the air supply mechanism 4, allowing the air delivered to the heating plate 1 by the air blower to be quickly heated. The water pipe 108 can be located on the same side as the heating pipe 106, and thus is located on the side of the heating plate 1 facing the air supply mechanism 4.

[0064] The three aforementioned steam generation structure embodiments all ensure that steam can be effectively dissipated toward the food, thereby adjusting the moisture content of the food and improving the food's taste. Furthermore, it can be seen that all three embodiments facilitate the integrated formation of the steam generation structure and the heating plate. This integrated formation of the steam generation structure and the heating plate ensures efficient heat transfer from the heating plate 1 to the steam generation structure, simplifies the assembly structure, reduces manufacturing costs, and reduces the space occupied within the air fryer.

[0065] The above are only preferred embodiments of the present application and are 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.
