The oven body 1 is provided with a cavity 11 with an opening on one side and at least one combustion chamber 12. In this embodiment, there are two combustion chambers, which are respectively arranged on the left and right outer sides of the cavity 11. Openings 111 are provided in the side walls of the cavity 11 at positions corresponding to the combustion chambers 12. The cavity 11 is connected to the combustion chambers 12 through the openings 111. Specifically, the oven body 1 comprises an outer shell assembly and an inner pot assembly disposed within the outer shell assembly. The inner pot assembly is provided with a cavity 11 with an opening on one side. Openings 111 are provided in the left and right side walls of the inner pot assembly, respectively. Two combustion chambers 12 are formed between the inner pot assembly and the outer shell assembly, located on the left and right outer sides of the inner pot assembly.

[0034] The burner 2 is detachably embedded in the combustion chamber 12, and its smoke outlet end extends into the cavity 11 through the opening 111. A smoke outlet 212 is provided on the smoke outlet end of the burner 2, and the smoke outlet 212 is communicated with the cavity 11, so that the burner 2 can be detached from the oven body 1, which is easy to disassemble, maintain and clean, so that the user can clean the burner and its surrounding areas more thoroughly, avoid the accumulation of oil and food residues, and help extend the service life of the gas oven, solving the problem that the burner and its surrounding areas of the existing gas oven are difficult to clean.

[0035] The protective cover 3 is positioned outside the opening 111 and the smoke outlet of the burner 2 and is removably connected to the inner surface of the side wall of the cavity 11. A plurality of smoke holes 321 are formed in the protective cover 3. In this embodiment, the plurality of smoke holes 321 are evenly spaced along the length of the protective cover 3 to achieve a uniform smoke distribution effect. The cavity 11 is connected to the smoke outlet 212 at the smoke outlet of the burner 2 through the smoke holes 321, thereby effectively preventing oil and food residue from splashing onto the burner 2. Since both the protective cover 3 and the burner 2 are removable, cleaning convenience is improved, and the protective cover 3 and the burner 2 can be easily removed in sequence for cleaning.

[0036] refer to Figure 1-3 In this embodiment, the protective cover 3 is in the shape of a prism with a larger outer end and a smaller inner end. The horizontal cross-section of the protective cover 3 is a trapezoid that gradually decreases from the burner 2 toward the cavity 11. This achieves the purpose of hiding and protecting the burner 2 while preventing oil and food residue from being easily deposited on the outer surface of the protective cover 3. The protective cover 3 includes a surrounding plate 31 and a baffle 32. The surrounding plate 31 is in the shape of a prism with a larger outer end and a smaller inner end. The surrounding plate 31 is sleeved outside the opening 111 and the smoke outlet end of the burner 2. One end of the surrounding plate 31 is detachably connected to the inner surface of the side wall of the cavity 11 by fasteners (such as screws), and the other end is connected to the baffle 32. In this embodiment, the surrounding plate 31 and the baffle 32 are integrally formed. A plurality of smoke holes 321 are provided on the baffle 32. The plurality of smoke holes 321 are evenly spaced along the length of the baffle 32. Each smoke hole 321 is preferably a vertically arranged strip hole to increase the unit ventilation area.

[0037] Specifically, the enclosure 31 has four sides, at least one of which is tilted from the burner 2 toward the baffle 32 and toward the interior of the enclosure 31. In this embodiment, all four sides are tilted from the burner 2 toward the baffle 32 and toward the interior of the enclosure 31, so that the enclosure 31 has a tapered structure. The baffle 32 is arranged vertically. Of course, the baffle 32 can also be designed to be tilted in the vertical direction, so that the smoke hole 321 can face the grilling pan 6 placed in the cavity 11.

[0038] An outwardly extending flange 33 is provided at one end of the enclosure 31 away from the baffle 32. The flange 33 is detachably connected to the inner surface of the side wall of the cavity 11 by fasteners (e.g., screws). Of course, a seal may be provided between the flange 33 and the inner surface of the side wall of the cavity 11 to improve the airtightness between the protective cover 3 and the side wall of the cavity 11, thereby preventing oil and food residue from seeping in from between the protective cover 3 and the side wall of the cavity 11 and falling onto the burner 2.

[0039] refer to Figure 1-3Specifically, a support portion 112 is protruding from the side wall of the cavity 11 to reliably support the grill pan 6. The protective cover 3 is disposed below the support portion 112, with the top of the protective cover 3 abutting against or having a clearance fit with the bottom of the support portion 112, thereby preventing grease and food residue from splashing between the protective cover 3 and the side wall of the cavity 11.
