[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0029] Referring to Figures 1 to 7 , the oven 100 proposed by the present application includes:

[0030] The furnace body 10 includes a bottom wall 11 and side walls 12 extending upward from the bottom wall 11. The bottom wall 11 and the side walls 12 enclose a furnace cavity 13. A plurality of limiting grooves 121 are provided at the upper edge of the side walls 12, and the plurality of limiting grooves 121 are arranged at intervals along the circumferential direction of the side walls 12. An air inlet 122 is provided at the bottom of the side walls 12.

[0031] The air damper 20 is movably arranged outside the side walls 12 to change the degree of shielding of the air inlet 122 during the movement process; and

[0032] The storage rack 30 includes a storage tray 31 and a plurality of support feet 32 provided on the bottom surface of the storage tray 31. The storage rack 30 has a high-position placement state and a low-position placement state. In the high-position placement state, the support feet 32 abut against the upper edge of the side walls 12. In the low-position placement state, the support feet 32 abut against the bottom wall surface of the limiting grooves 121.

[0033] In this embodiment, the furnace body 10 and the storage rack 30 are generally made of high-temperature resistant materials, such as pig iron. In order to prevent heat dissipation or scalding users, the furnace body 10 can also be made of heat-insulating materials. Changing the degree of shielding of the air inlet 122 by the air damper 20 can change the oxygen supply of the fuel, thereby adjusting the heat release of the fuel. The storage rack 30 can directly place food or be used to place other containers, such as teapots, etc. Generally, since the storage rack 30 needs to be in contact with food, the storage rack 30 also needs to be made of food-contact grade materials.

[0034] The utility model adjusts the air intake volume of the air inlet 122 through the movably arranged air damper 20. On this basis, by providing the limiting grooves 121 at the upper edge of the side walls 12 of the furnace body 10, the storage rack 30 has multiple placement states at different heights to adjust the height of the storage tray 31. In this way, by changing the thermal radiation distance between the food on the storage tray 31 and the fuel, the purpose of fine grilling is achieved, that is, different foods can be baked at different heights. Particularly, when the storage rack 30 is in the low-position placement state, the support feet 32 of the storage rack 30 are located in the limiting grooves 121, and the side wall surfaces of the limiting grooves 121 can also limit the rotation of the storage rack 30 around the vertical axis by abutting against the support feet 32, so that the placement of the storage rack 30 is more stable.

[0035] Further, the support feet 32 are in limiting cooperation with the side walls 12 in the radial direction. In this way, the lateral movement of the storage rack 30 along the horizontal plane can be restricted.

[0036] Further, the support feet 32 include a support portion 321 and a stop portion 322. The support portion 321 is connected to the storage tray 31. The stop portion 322 extends downward from the lower end of the support portion 321. The stop portion 322 is in limit fit with the inner wall surface of the side wall 12 in the radial direction. In the high-position placement state, the support portion 321 abuts against the upper edge of the side wall 12. In the low-position placement state, the support portion 321 abuts against the bottom wall surface of the limit groove 121. In this embodiment, the stop portion 322 is located inside the furnace cavity 13, so that the protrusion degree of the support feet 32 on the outer peripheral surface of the side wall 12 can be reduced, and further the risk that an external object rubs against the support feet 32 and causes the furnace body 10 to tip over can be reduced.

[0037] Further, the side wall 12 is cylindrical; the air damper 20 is annular and rotatably arranged on the periphery of the side wall 12. In this embodiment, since the side wall 12 is cylindrical, the air damper 20 can be directly rotatably sleeved on the periphery of the side wall 12, which can simplify the structure, make the manufacturing cost of the oven 100 lower, and be easy to use.

[0038] Further, an annular recess 123 is formed by radially inwardly recessing the outer peripheral surface of the lower end of the side wall 12, and the air damper 20 is rotatably embedded in the annular recess 123. In this embodiment, the outer dimension of the lower end of the oven 100 can be reduced in this way, and the annular recess 123 can also play a role in limiting and guiding the air damper 20, making the air damper 20 easier to rotate along the preset axis and height.

[0039] Further, the air inlet 122 is opened on the side wall surface of the annular recess 123; the air damper 20 includes a bottom ring portion 21 and a side ring portion 22. The bottom ring portion 21 extends along the horizontal plane, and the side ring portion 22 extends upward from the outer edge of the bottom ring portion 21; the bottom ring portion 21 is located below the side wall 12, and the side ring portion 22 is embedded in the annular recess 123. A ventilation slot 221 adapted to the size of the air inlet 122 is formed on the upper edge of the side ring portion 22. In this embodiment, by providing the ventilation slot 221, the air inlet 122 can be completely opened, and the rest of the side ring portion 22 is used to block the air inlet 122, so that the shielding degree of the air inlet 122 can be continuously changed; and by providing the side ring portion 22, the structural strength of the air damper 20 can be ensured. Preferably, in order to facilitate the rotation of the air damper 20, the air damper 20 further includes a lug 23 provided on the outer peripheral surface of the side ring portion 22.

[0040] Further, in order to enable the user to quickly and accurately grasp the position where the air inlet 122 is completely opened during the rotation of the air damper 20, a positioning protrusion 124 is provided on the outer peripheral surface of the side wall 12, and the positioning protrusion 124 is provided adjacent to one side wall surface of the air inlet 122; in the circumferential direction of the air damper 20, the ventilation slot 221 has opposite side wall surfaces 222, 223; when the air inlet 122 is completely exposed from the ventilation slot 221, one side wall surface 222 of the ventilation slot 221 abuts against the positioning protrusion 124.

[0041] Further, an annular shoulder 125 is formed on the inner wall surface of the side wall 12 corresponding to the upper edge of the annular recess 123. The oven 100 further includes a fuel rack 40 placed on the annular shoulder 125. An ash - falling cavity 14 is formed between the fuel rack 40 and the bottom wall 11. The inner diameter of the upper part of the side wall 12 is gradually enlarged from bottom to top. In this embodiment, the annular recess 123 and the annular shoulder 125 are formed at corresponding positions on the side wall 12, making the related structure more compact. By providing the annular shoulder 125, the fuel can be separated from the fuel ash, and the fuel is more greatly elevated, allowing more air to contact the fuel, thereby improving the combustion efficiency. The inner cavity of the side wall 12 is larger at the top and smaller at the bottom, which is beneficial for quickly installing the fuel rack 40 onto the annular shoulder 125.

[0042] Further, the oven 100 further includes a base 50 that is interchangeable with the storage rack 30. The furnace body 10 is placed on the upper surface of the base 50. The outer edge of the base 50 protrudes beyond the outer edge of the lower end of the bottom wall 11. The bottom ring portion 21 is located between the base 50 and the bottom wall 11, and the bottom ring portion 21 is rotatably engaged with the upper surface of the base 50. In this embodiment, by providing the support base to support the furnace body 10, the furnace body 10 is elevated relative to the ground, reducing the heat transfer of the furnace body 10 to the ground, and thus improving the usage efficiency of the oven 100. The interchangeable setting of the base 50 and the storage rack 30 means that they can be functionally replaced with each other, but their specific structures can be different. For example, the base 50 and the storage rack 30 have support feet with the same structure, but the grille patterns of the main body parts are different. The interchange of the base 50 and the storage rack 30 can improve the flexibility of use.

[0043] Further, the oven 100 further includes a handle 60. The two ends of the handle 60 are respectively rotatably connected to the upper edge of the side wall 12. The outer edge of the storage tray 31 is located inside the sweeping trajectory of the handle 60 and a gap is formed between the outer edge of the storage tray 31 and the sweeping trajectory of the handle 60. In this embodiment, by providing the handle 60, it is convenient to transfer the oven 100. The outer edge of the storage tray 31 deviates inward from the sweeping trajectory of the handle 60, which can prevent the handle 60 from touching the storage tray 31 during the rotation of the handle 60, thereby reducing the risk of accidental dropping of the storage rack 30.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, not to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. And these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
