[0037] Example 1

[0038] In existing technology, the air inlet and outlet of the heating cavity of a drawer-type microwave oven are located on the left and right side walls of the inner cavity, respectively. The design of the air inlet and outlet paths of the circulating air is unreasonable, resulting in uneven heating of food and poor cooking effect.

[0039] To solve the above technical problems, such as Figures 1-8 As shown, this embodiment proposes a cooking device 100, which includes:

[0040] Furnace body 1, wherein the furnace body 1 has a heating chamber 3, and a convection component 5 is provided on the furnace body 1, wherein the convection component 5 is used to form circulating air in the heating chamber 3;

[0041] The furnace body 1 includes an inner liner 12, and the heating chamber 3 is formed inside the inner liner 12. The inner liner 12 is provided with an air inlet structure and an air outlet 1203 communicating with the heating chamber 3. The air inlet structure includes a first air inlet 1201 and a second air inlet 1202. The first air inlet 1201 and the second air inlet 1202 are symmetrically arranged on two side walls 122 of the inner liner 12, which is conducive to the uniform entry of circulating air and improves the heating uniformity. The air outlet 1203 is arranged on the rear wall 124 of the inner liner 12, forming a reasonable air inlet and outlet path with the air inlet, promoting the circulation of hot air.

[0042] This embodiment proposes a cooking device 100. A first air inlet 1201 and a second air inlet 1202 are symmetrically arranged on the two side walls 122 of the inner pot 12, and an air outlet 1203 is arranged on the rear wall 124 of the inner pot 12. The air outlet 1203, together with the first air inlet 1201 and the second air inlet 1202, forms a reasonable air inlet and outlet path, which promotes more uniform circulation of hot air in the heating chamber 3, thereby improving the heating uniformity of food, resulting in better cooking effect and improving user satisfaction.

[0043] As a preferred example of this application, such as Figures 3-5 As shown, a microwave heating component 4 is installed on the oven body 1. The microwave heating component 4 is used to supply microwaves to the heating cavity 3, and the microwave heating component 4 is installed on the top wall 121 of the inner liner 12. This design has many advantages: First, it can make the microwaves cover the food in the heating cavity 3 more evenly, improving the heating uniformity of the food; Second, the structural layout is reasonable. Placing the microwave heating component 4 on the top wall 121 will not occupy the space of the side wall 122 or rear wall 124 of the inner liner 12, making the internal space of the heating cavity 3 more regular, which is conducive to the placement of food and the cooking process; Third, the position of the top wall 121 is relatively open, which facilitates the installation and removal of the microwave heating component 4; Fourth, the position is relatively independent from that of the convection component 5, so they will not interfere with each other; it is convenient to work in conjunction with the convection component 5.

[0044] In this application, the convection component 5 and the microwave heating component 4 work together to achieve a dual heating method of microwave heating and convection heating. Microwave heating can quickly penetrate food, causing the interior of the food to heat up rapidly, while convection heating can create a caramelized crust on the surface of the food, while ensuring uniform heating inside the food. This synergistic effect greatly improves cooking efficiency and cooking quality.

[0045] As a preferred example of this application, such as Figure 4As shown, the inner pot 12 also includes a bottom wall 123, which is integrally formed with the two side walls 122. This design serves multiple purposes: First, it simplifies the manufacturing process, reduces the number of connection points between components, thereby improving the overall strength of the inner pot 12, and consequently enhancing the overall strength and durability of the cooking equipment 100. Second, the integral structure also helps reduce assembly errors, ensuring the precision and stability of the cooking equipment 100. Third, it improves production efficiency, enabling the cooking equipment 100 to be brought to market more quickly.

[0046] As a preferred example of this application, such as Figure 4 and Figure 5 As shown, the side wall 122 includes a connecting plate 1221, which is inclined at the connection between the side wall 122 and the top wall 121, and the air inlet structure is provided on the connecting plate 1221.

[0047] The design offers the following advantages: 1. The inclined connecting plate 1221 allows the air inlet structure to communicate with the internal space of the heating chamber 3 at a more reasonable angle and position. 2. The inclined connecting plate 1221 guides air more smoothly into the heating chamber 3, reducing airflow resistance during the intake process; this helps improve the working efficiency of the convection fan 51, reduces energy consumption, and ensures stable airflow. 3. It improves space utilization; the inclined connecting plate 1221 provides more possibilities for the installation and layout of other components. 4. The inclined setting of the connecting plate 1221 increases the connection strength between the side wall 122 and the top wall 121, making the entire inner liner 12 structure more stable. 5. The inclined connecting plate 1221 can disperse the stress at the connection between the side wall 122 and the top wall 121, avoiding damage caused by stress concentration, which helps extend the service life of the equipment and improve its reliability.

[0048] As a preferred example of this application, such as Figure 7 and Figure 8 As shown, the convection assembly 5 includes a convection fan 51 and a fan shroud 52. The convection fan 51 is located on the rear side of the inner liner 12, and its position corresponds to the air outlet 1203. This effectively guides air to flow out of the heating chamber 3, forming a smooth airflow circulation. This layout conforms to the principle of airflow, reduces airflow resistance, and improves the working efficiency of the convection fan 51. The convection fan 51 is installed inside the fan shroud 52; the fan shroud 52 not only protects the convection fan 51 but also guides and straightens the airflow, making the airflow more evenly blown into the heating chamber 3, thus improving heating uniformity.

[0049] Air inside the heating chamber 3 is drawn into the fan shroud 52 by the convection fan 51, and at the same time, air inside the fan shroud 52 is blown into the heating chamber 3, thus forming circulating air, thereby making the temperature inside the heating chamber 3 uniform.

[0050] As a preferred example of this application, such as Figure 7 As shown, the convection assembly 5 also includes a mounting cover 54, which is disposed on the outside of the connecting plate 1221 and is connected to the fan cover 52 through a connecting port 55. This design makes the mounting cover 54 an important channel connecting the fan cover 52 and the air inlet structure of the heating chamber 3, realizing effective air circulation inside and outside the heating chamber 3.

[0051] As a preferred example of this application, such as Figure 7 As shown, the convection assembly 5 also includes a heating element 53, which is positioned at the corresponding location of the air inlet structure. First, because the heating element 53 is positioned at the corresponding location of the air inlet structure, when air enters the heating chamber 3 from the air inlet, it is first heated by the heating element 53. This design preheats the air before it enters the heating chamber 3, improving heating efficiency and ensuring a rapid temperature rise within the heating chamber 3. Second, the heating element 53 works in conjunction with the convection fan 51 to form a hot air circulation system. The convection fan 51 drives airflow, causing the heated air to circulate within the heating chamber 3, further improving heating uniformity; uniform heating is achieved for both the surface and interior of the food, thus ensuring optimal cooking results.

[0052] As a preferred example of this application, such as Figure 3 As shown, the heating element 53 is installed inside the mounting cover 54. This integrated design makes the structure of the convection assembly 5 more compact, reduces the size of the device, and also facilitates the coordinated operation of the components.

[0053] In this way, the air in the heating chamber 3 is drawn into the fan cover 52, and at the same time the convection fan 51 blows the air into the mounting cover 54 to be heated by the heating tube 53. Then the heated hot air is blown into the heating chamber 3, thus forming a circulating hot air, which makes the food heated more evenly and further enhances the cooking effect of the food.

[0054] As a preferred example of this application, such as Figure 3 As shown, the connecting plate 1221 is inclined toward the center of the heating chamber 3, and the angle between the connecting plate 1221 and the side wall 122 is α, where α is 105~155°.

[0055] As a preferred example of this application, in this embodiment, the angle α between the connecting plate 1221 and the side wall 122 is 135°.

[0056] As a preferred example of this application, such as Figure 7 As shown, a first heat insulation component 7 is provided on the outside of the fan cover 52. This design reduces heat loss inside the fan cover 52, thereby improving the overall efficiency of the convection component 5 and reducing energy consumption. On the other hand, it minimizes the temperature rise of the components on the outside of the fan cover 52, preventing them from being damaged by high temperatures, reducing wear and aging of the equipment, and extending the service life of the equipment.

[0057] As a preferred example of this application, such as Figure 7 As shown, the first heat insulation component 7 includes a first heat insulation element 71, which is disposed on the outside of the fan cover 52.

[0058] The first heat insulation component 71 is directly installed on the outside of the fan cover 52, serving as the first layer of heat insulation barrier. Its core function is to initially block the heat emitted by the fan cover 52 from being transferred outward, reducing the direct impact of heat on the surrounding environment.

[0059] Specifically, the material of the first heat insulation component 71 is not specifically limited.

[0060] As a preferred example of this application, such as Figure 7 As shown, the first heat insulation component 7 also includes a first heat insulation frame 72, which covers the outside of the first heat insulation element 71. The first heat insulation frame 72, covering the outside of the first heat insulation element 71, serves to further reinforce and protect it. It not only enhances the overall structural strength of the first heat insulation component 7, preventing the first heat insulation element 71 from shifting or being damaged due to vibration or airflow impact during fan operation, but also provides additional support for the first heat insulation element 71, ensuring it always fits tightly against the fan cover 52 and maintains good heat insulation performance.

[0061] Specifically, the material of the first heat insulation frame 72 is not specifically limited. The material of the first heat insulation frame 72 can be aluminum alloy or stainless steel, but is not limited to these.

[0062] In this embodiment, the first heat insulation frame 72 is made of aluminum alloy. Aluminum alloy has advantages such as light weight, high strength, and corrosion resistance, which can effectively reduce the weight of the entire first heat insulation component 7 while ensuring its structural stability.

[0063] As a preferred example of this application, such as Figure 7 As shown, a second heat insulation component 8 is provided on the outside of the mounting cover 54. This design, on the one hand, reduces heat loss inside the mounting cover 54, which can improve the overall efficiency of the convection component 5 and reduce energy consumption; on the other hand, the temperature rise of the components on the outside of the mounting cover 54 is small, avoiding damage from high temperatures, reducing wear and aging of the equipment, and extending the service life of the equipment.

[0064] As a preferred example of this application, such as Figure 7 As shown, the second heat insulation component 8 includes a second heat insulation element 81, which covers the outside of the mounting cover 54.

[0065] The second heat insulation element 81 is directly installed on the outside of the mounting cover 54, serving as the first layer of heat insulation barrier. Its core function is to prevent heat from the inside of the mounting cover 54 from being transferred outward, thereby reducing the direct impact of heat on the surrounding environment.

[0066] Specifically, the material of the second heat insulation component 81 is not specifically limited.

[0067] As a preferred example of this application, such as Figure 7 As shown, the second heat insulation component 8 also includes a second heat insulation frame 82, which covers the outside of the second heat insulation component 81.

[0068] The second heat insulation bracket 82 is installed on the outside of the second heat insulation component 81, serving to support, fix, and protect it. On the one hand, it can enhance the overall structural strength of the second heat insulation component 8, preventing the second heat insulation component 81 from shifting, deforming, or being damaged under external forces such as equipment operation vibration and airflow impact; on the other hand, it provides a stable installation base for the second heat insulation component 81, ensuring that it always fits tightly against the mounting cover 54 and maintains a good heat insulation state.

[0069] The furnace body 1 also includes an outer shell 11, and the inner liner 12 is disposed inside the outer shell 11.

[0070] The cooking device 100 also includes a drawer 2, which is slidably mounted on the oven body 1 for easy insertion and removal of food by the user; the drawer 2 is provided with a storage cavity 6 for storing food to be heated.

[0071] As for other related components of the cooking device 100, since their specific structures and assembly relationships are all existing technologies, they will not be described in detail here.

[0072] This embodiment proposes a cooking device 100. A first air inlet 1201 and a second air inlet 1202 are symmetrically arranged on the two side walls 122 of the inner pot 12, and an air outlet 1203 is arranged on the rear wall 124 of the inner pot 12. The air outlet 1203, together with the first air inlet 1201 and the second air inlet 1202, forms a reasonable air inlet and outlet path, which promotes more uniform circulation of hot air in the heating chamber 3, thereby improving the heating uniformity of food, resulting in better cooking effect and improving user satisfaction.

[0073] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
