[0043] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0044] Please refer to Figures 1-6 The present invention provides an oven comprising an outer shell structure, an inner liner 1, a charcoal basin structure 2, and an air inlet structure. The inner liner 1 is disposed within the outer shell structure and includes a cooking cavity 100 having a first opening at the front. The charcoal basin structure 2 includes a charcoal basin 21, which is mounted within the outer shell structure and disposed below the inner liner 1 and is used to hold charcoal. The charcoal basin 21 is provided with a first air inlet 211 and a first air outlet 212, which communicates with the exterior of the oven. The air inlet structure includes a first air duct 33, a first fan blade structure 71, and a drive structure. The first air duct 33 is provided with a second air inlet 331 and a second air outlet 332. The second air inlet 331 communicates with the outside of the oven, and the second air outlet 332 communicates with the first air inlet 211. The first air duct 33 is located on one side of the oven liner. The first fan blade structure 71 is disposed within the first air duct 33 and is in transmission connection with the drive structure. The drive structure is capable of driving the fan blade structure to rotate, thereby creating a negative pressure within the first air duct 33. This allows air from outside the oven to enter the charcoal basin 21 through the first air duct 33, thereby providing oxygen for the combustion of the charcoal blocks. The heat generated by the combustion of the charcoal blocks enters the cooking cavity 100 through the bottom side of the inner container 1, thereby grilling the food within the cooking cavity 100. The smoke generated during the combustion of the charcoal blocks is discharged from the oven liner through the first air outlet 212.

[0045] The oven provided by the present invention isolates the cooking chamber 100 from the charcoal blocks by positioning the charcoal basin structure 2 below the inner pot 1. This prevents grease from the food in the cooking chamber 100 from dripping into the burning charcoal blocks during cooking. This resolves the safety hazard associated with placing food directly above the charcoal basin 21, which can cause grease to drip into the charcoal blocks and ignite. Furthermore, by providing the outer shell structure, inner pot 1, and air inlet structure, the cooking chamber 100 and charcoal basin structure 2 are relatively sealed, effectively reducing the possibility of burns to the user during cooking. Furthermore, smoke generated by the charcoal blocks can only be discharged through the first air outlet 212. This effectively controls the direction of smoke emission, preventing combustion smoke from directly reaching the user, and improving the user experience.

[0046] Optionally, the drive structure includes a rotating handle 5 and a first rotating shaft 65 connected to each other. The first rotating shaft 65 is mounted on the inner container 1 and / or the outer shell structure, and the first fan blade structure 71 is mounted on the rotating shaft. The rotating handle 5 is arranged to extend out of the outer shell structure. The user manually drives the rotating handle 5 to rotate the first rotating shaft 65, thereby rotating the first fan blade structure 71, thereby generating negative pressure in the first air duct 33. The first fan blade structure 71 can be driven without the need for a power source, making it convenient for the user to carry the oven outdoors for use.

[0047] Optionally, the driving structure also includes a first gear 62, a second gear 64 and a second rotating shaft. The first gear 62 is installed on the first rotating shaft 65, the second rotating shaft is installed on the first air duct 33, the second gear 64 is installed on the second rotating shaft and is meshed and connected with the first gear 62. The first fan blade structure 71 is installed on the second gear 64. The number of teeth of the first gear 62 is greater than the number of teeth of the second gear 64, so that the rotation speed of the first fan blade structure 71 is greater than the rotation speed of the rotating handle 5. The user only needs to rotate the rotating handle 5 by a smaller angle to drive the first fan blade structure 71 to rotate a larger angle, thereby increasing the air intake of the first air duct 33.

[0048] Optionally, the second air inlet 331 is disposed on the side of the first air duct 33 facing away from the cooking cavity 100. Furthermore, an air regulating plate 4 is provided with air regulating holes 41. The air regulating plate 4 is disposed on the side of the first air duct 33 facing away from the cooking cavity 100 and is configured to block or open the second air inlet 331, thereby adjusting the amount of air entering the first air duct 33. Furthermore, when the second air inlet 331 is completely blocked, the oven can still maintain the temperature of the food.

[0049] Optionally, the driving structure includes a driving motor. In this embodiment, the oven is suitable for indoor or outdoor use with a power supply.

[0050] Optionally, a circulating hot air structure is also included, which includes a first circulating air cavity 200, a second fan blade structure 72, and a circulating air duct group. The first circulating air cavity 200 is arranged on the inner pot 1, and a third air inlet hole 341 is opened on the first circulating air cavity 200. The cooking cavity 100 is connected to the first circulating air cavity 200 through the third air inlet hole 341. The second fan blade structure 72 is arranged in the first circulating air cavity 200 and is installed on the first rotating shaft 65. The circulating air duct group is arranged between the charcoal basin 21 and the inner pot 1. One end of the circulating air duct group is connected to the first circulating air cavity 200, and the other end is connected to the cooking cavity 100. When the first rotating shaft 65 rotates, the colder air in the cooking cavity 100 that has exchanged heat with the food can be pumped into the first circulating air cavity 200, and then flows into the circulating air duct group. The charcoal blocks in the charcoal basin 21 burn to heat the colder air in the circulating air duct. The hot air formed after heating is blown into the cooking cavity 100 again to heat the food. As long as the second fan blade structure 72 continues to operate, the above-mentioned hot air circulation will continue, thereby achieving uniform heating of the food and improving cooking efficiency.

[0051] Optionally, the driving structure also includes a third gear 61, a fourth gear 63 and a third rotating shaft. The third gear 61 is installed on the first rotating shaft 65, and the third rotating shaft is installed on the side wall of the first circulating air cavity 200. The fourth gear 63 is installed on the third rotating shaft and is meshed with the third gear 61 for transmission connection. The second fan blade structure 72 is installed on the fourth gear 63. The number of teeth of the third gear 61 is greater than the number of teeth of the fourth gear 63, so that the rotation speed of the second fan blade structure 72 is greater than the rotation speed of the rotating handle 5. The user only needs to rotate the rotating handle 5 by a smaller angle to drive the second fan blade structure 72 to rotate a larger angle, thereby increasing the air intake of the first circulating air cavity 200.

[0052] Optionally, the first circulating air cavity 200 is arranged on the rear side of the cooking cavity 100, and the circulating air duct group includes a second air duct 31 and a third air duct 32 that are connected to each other, the second air duct 31 is connected to the lower end of the first circulating air cavity 200, and the third air duct 32 is connected to the left and / or right side of the cooking cavity 100, thereby realizing circulating heating of the gas in the cooking cavity 100.

[0053] Optionally, the inner pot 1 includes an inner pot enclosure 11 and a rear plate 12 disposed behind the inner pot enclosure 11. The inner pot enclosure 11 and the rear plate 12 together form a cooking cavity 100 on the front side. The circulating hot air structure further includes a first cover shell 34 and a second cover shell 35. The first cover shell 34 and the rear plate 12 together form a first circulating air cavity 200. A third air inlet 341 is provided on the first cover shell 34. The second cover shell 35 and the left side wall and / or the right side wall of the inner pot enclosure 11 together form a second circulating air cavity 400. The second circulating air cavity 400 is provided with a third air outlet 110 communicating with the cooking cavity 100. The third air duct 32 is connected to the second circulating air cavity 400. The structure is simple and compact.

[0054] Optionally, the first air duct 33 is disposed outside the rear panel 12. The outer shell structure includes an outer shell panel and a door mounted on the front side of the outer shell panel. The rear side of the outer shell panel is connected to the rear panel 12 to form a housing cavity having a second opening on the front side. The inner liner 1 and the charcoal basin structure 2 are both disposed within the housing cavity. The bottom of the rear panel 12 is provided with an air hole, and the second air outlet 332 is connected to the first air inlet 211 through the air hole. The door can close and open the second opening to facilitate removal of the charcoal basin 21, cleaning of carbon ash, and / or addition of charcoal blocks.

[0055] Furthermore, when the door body closes the second opening, the first opening can also be closed at the same time, so that the cooking cavity 100 is relatively closed, preventing high-temperature gas from leaking between the inner pot 1 and the outer shell panel, which is conducive to quick cooking.

[0056] Optionally, the charcoal basin structure 2 also includes a charcoal rack 22, which is arranged in the charcoal basin 21 and can divide the space in the charcoal basin 21 into an upper cavity 302 and a lower cavity 301 arranged upper and lower. The charcoal blocks are placed on the charcoal rack 22. By setting the charcoal rack 22, the charcoal blocks can be placed on the charcoal rack 22, and the ashes produced after combustion can fall into the charcoal basin 21, thereby improving the combustion efficiency and combustion speed of the charcoal blocks.

[0057] Optionally, a plurality of first air inlet holes 211 and first air outlet holes 212 are provided, with some first air inlet holes 211 and some first air outlet holes 212 being provided above the mesh surface 221 of the charcoal rack 22, while some first air inlet holes 211 and some first air outlet holes 212 are provided below the mesh surface 221. In this way, the air in the first air duct 33 can be distributed between the upper cavity 302 and the lower cavity 301, thereby improving the combustion speed and efficiency of the charcoal blocks and allowing smoke generated by the combustion of the charcoal blocks to be quickly discharged.

[0058] Optionally, a grill 81 and / or a baking tray 82 is also included, and a slide groove 111 is also provided in the inner pot 1. The grill 81 and / or the baking tray 82 can be detachably installed in the cooking cavity 100 through the slide groove 111, and food can be placed on the grill 81 and / or the baking tray 82 for cooking.

The temperature detection and display structure 9 includes an interconnected temperature display structure and a temperature detection probe. The temperature display structure is mounted on the outside of the outer shell structure, and the temperature detection probe is disposed on the outside of the inner pot 1. When the temperature is low, the rotation of the rotary handle 5 can be accelerated to increase the combustion air and simultaneously accelerate the heat exchange rate within the cooking cavity 100, thereby increasing the cooking temperature. When the temperature is high, the rotation of the rotary handle 5 can be reduced to reduce the combustion air and simultaneously reduce the heat exchange rate within the cooking cavity 100, thereby lowering the cooking temperature.

[0060] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
