The front end of the bracket 31 is connected to the air inlet 10. The combustion zone is connected to the air inlet 10. In this way, external air can enter the combustion zone through the air inlet 10, providing sufficient air for the burner 32, solving the oxygen supply problem of the gas oven. After the combustion zone burns, a certain negative pressure is formed, so that air can enter the combustion zone from the air inlet 10 to ensure the supply of air.
[0041] In a preferred embodiment of the utility model, the bottom of the cover body 41 is recessed downward to form a U-shaped groove 411 corresponding to the burner assembly 3, and an opening 4111 corresponding to the bracket 31 is provided at the bottom of the U-shaped groove 411. The bracket 31 is inserted into the U-shaped groove 411 through the opening 4111, and both ends of the bracket 31 are connected to the opening 4111, so that the left and right sides and the rear side of the bracket 31 respectively form a sealed combustion zone with the cover body 41 and the cavity 2, so that the heat of the combustion zone is transferred to the interior of the cavity 2 to the maximum extent, thereby improving the thermal efficiency of the product.
[0042] In a preferred embodiment of the present invention, Figure 1-5The shell 1 shown includes a front plate 11 and a bottom plate 12, and the front side of the front plate 11 is connected to a door body 13; the front plate 11 is provided with an air inlet 10 on one side below the cavity 2, and a bracket 31 is located above the bottom plate 12, and the bracket 31 and the bottom plate 12 form a sandwich 120.

When the fan 51 is working, the air inside the electrical compartment 5 is blown out to form a negative pressure cabin, so that the external air can only be sucked in from the air inlet 10 of the front plate 11, which can increase the intake of fresh air and accelerate the flow of external air. The present application adopts a two-way independent supply air duct to ensure sufficient combustion.
[0044] In a preferred embodiment of the present invention, Figure 1-5 The bracket 31 shown includes a support plate 311, the front end of the support plate 311 is tilted upward and forward to form a first flange 3111, and the first flange 3111 abuts against the middle of the air inlet hole 10 to divert the air entering the air inlet hole 10; wherein the air enters the combustion zone and the interlayer 120 respectively through the air inlet hole 10 and the first flange 3111.

As the gas is ejected from the nozzle 323, a negative pressure area is formed near the nozzle 323. When the fan 51 is working, the air in the electrical compartment 5 is blown out to form a negative pressure compartment. The air can only be sucked in from the air inlet 10 of the front plate 11, which increases the intake of fresh air. At the same time, fresh air enters the electrical compartment 5. Since there is a negative pressure area at the nozzle 323, the fresh air in the electrical compartment 5 can be smoothly ejected into the burner 32, thereby increasing the air volume.
