When the burner 64 is working in the outer ring combustion, the required secondary air enters from the air inlet 11 on the pot rack, is preheated through the first cavity 4 of the pot rack, and then comes out from the air outlet 21 of the pot rack and enters the burner 64 for combustion, which has the effect of increasing the temperature of the combustion area. The above structure optimizes the preheating of the secondary air to achieve energy efficiency improvement.

[0043] In this embodiment, the disc-shaped pot rack is divided into three layers, including a first layer 1, a second layer 2 and a third layer 3 which are arranged in sequence from bottom to top.

In other feasible schemes, a second protrusion can also be provided on the second layer 2 for contacting the inner edge of the first layer 1.

[0046] A support foot 12 is provided below the first layer 1 to cooperate with the water receiving tray 63 to prevent the air inlet 11 from being blocked and to maintain smooth air intake.

[0047] The pot rack is in the shape of a groove, with a through hole in the center that matches the burner 64. A flange 13 is provided on the inner edge of the first layer 1, and the flange 13 is matched with the outer wall of the burner 64 in a gap to enhance strength and reduce mechanical thermal deformation. The inner edge diameter of the second layer 2 is larger than the inner edge diameter of the first layer 1, so that after the first layer 1 is connected to the circumferential outer wall of the burner 64, the gap between the inner edge of the second layer 2 and the circumferential outer wall of the burner 64 forms the air outlet 21, which reduces the internal pressure of the second cavity 5 under high temperature conditions, balances the pressure difference between the inside and outside, and effectively reduces the mechanical damage and abnormal noise of the pot rack.

[0048] The air required for the outer ring combustion of the burner 64 enters through the air inlet 11 arranged on the first layer 1, is preheated through the first cavity 4 composed of the second layer 2 and the first layer 1, and then comes out from the air outlet 21 formed by the second layer 2 and the outer wall of the burner 64, and enters the burner 64 to supply combustion. Its function is to increase the temperature of the combustion area, achieve energy efficiency improvement, make the heating effect of the pot rack with disc better, and achieve the technical effect of energy efficiency improvement.

[0049] The second layer 2 and the third layer 3 form a second cavity 5 therebetween. The second cavity 5 mainly serves to insulate heat and reduce heat transfer downward.

[0050] Further, such as Figure 5 As shown, the second layer 2 is provided with a pressure relief hole 23 connecting the first cavity 4 and the second cavity 5. The heated air in the second cavity 5 can be discharged into the first cavity 4 to relieve pressure.

[0051] In summary, the pot rack comprises a third layer 3, a second layer 2, and a first layer 1; the inner edge of the second layer 2 is fixedly connected to the lower end face of the inner edge of the third layer 3, and its outer edge is fixedly connected to the lower end face of the outer edge of the third layer 3; the outer edge of the first layer 1 is fixedly connected to the outer edge of the third layer 3, and a first protrusion 22 is arranged around the inner edge of the first layer 1 to contact the lower end face of the inner edge of the second layer 2, so as to form the pot rack; the third layer 3 is provided with a pot rack foot piece 31 for supporting the pot; the second layer 2 is provided with a plurality of pressure relief holes 23, whose function is to reduce the pressure in the second cavity 5 under high temperature conditions, and the effect is to reduce the mechanical damage and abnormal noise of the pot rack; the inner edge of the first layer 1 is provided with a first protrusion 22, which has the functions of supporting, enhancing strength, and ensuring the size stability of the air outlet 21; the bottom surface of the first layer 1 is provided with a plurality of air inlet holes 11, whose functions are: the gas stove plays the role of air intake during combustion, the coating processing of the pot rack plays the role of exhaust and pressure reduction, and it has the function of drainage when it is placed in water for cleaning.

The outer edge of the first layer 1 and the outer edge of the second layer 2 are both connected to the outer edge of the third layer 3, and the specific connection method can be the same as the connection method in Example 1. The inner edge of the first layer 1 is closedly connected to the inner edge of the second layer 2. The inner edge diameter of the third layer 3 is larger than the inner edge diameter of the second layer 2, so that after the second layer 2 is connected to the circumferential outer wall of the burner 64, the gap between the inner edge of the third layer 3 and the circumferential outer wall of the burner 64 forms the air outlet 21. The air inlet 11 is arranged on the first layer 1. The second layer 2 is provided with air holes 24 that penetrate the upper and lower surfaces thereof, so that the first gap 71 and the second gap 72 are connected to form the first cavity 4. The outside air flows in from the air inlet 11 of the first layer 1, is preheated through the first gap 71 of the combination of the second layer 2 and the first layer 1, further enters the second gap 72 through the air holes 24 provided in the second layer 2 for further preheating, and further comes out from the air outlet 21 formed by the third layer 3 and the inner edge of the second layer 2, and enters the burner 64 for combustion. Its function is to increase the temperature of the combustion area, achieve energy efficiency improvement, make the heating effect of the pot rack with disc better, and achieve energy efficiency improvement.

[0055] The inner edge of the second layer 2 is provided with a third protrusion 25 , which abuts against the inner edge of the third layer 3 to play a supporting role and maintain the shape of the air outlet 21 .

[0056] The stove provided by the utility model includes the above-mentioned pot rack. Since the stove provided by the utility model uses the above-mentioned pot rack, the stove provided by the utility model also has the advantages of the pot rack.
