Description

technical field [0001] The invention belongs to the technical field of household gas stoves, and in particular relates to a high-efficiency split-type infrared burner for an infrared stove. Background technique [0002] For a long time, infrared stoves have become a model for many brands in the industry to compete and catch up because of their superiority in performance indicators such as high efficiency and energy saving, low-carbon environmental protection, cleanliness, uniform heating, and strong wind resistance, and have also become a model for many users. The first choice to buy. Infrared stoves are the product of infrared burners applied to civilian stoves. The infrared burner is designed with a completely premixed combustion method. When the burner is working, the combustible mixture is burned between the inner net and the outer net of the porous combustion radiation plate, and the burning surface temperature is as high as 1100 °C. The working principle of the commo...

AI Technical Summary

Problems solved by technology

[0003] 1. The infrared burner adopts an integral structure design. The ejector naturally injects air into the burner cavity through the gas pressure. Since the mixing cavity is a columnar structure, there is no design of a shunt structure, which is prone to local uneven combustion and local high temperature , increasing the chance of nitrogen oxide formation

[0004] 2. The infrared burner adopts an integral structure design. The ejector naturally ejects air into the burner cavity through the gas pressure. Since the mixing chamber is a columnar structure, there is no design of a shunt structure, and the gas and air are in the ejector and the furnace chamber. The internal mixing time is short, the gas and air are not fully premixed, and a part of the gas layer fluid is formed in the furnace cavity, which is likely to cause defects such as incomplete combustion and low thermal efficiency

[0005] 3. The infrared burner adopts an integral structure design. The ejector naturally ejects air into the burner cavity through the gas pressure. Due to the unreasonable design of the porous combustion radiation plate structure, the resistance of the head is large, which reduces the primary air of the ejector. Therefore, the gas-air mixture cannot achieve complete combustion once it reaches the combustion zone, and secondary air is needed to achieve complete combustion, and then the flame is elongated and the thermal efficiency decreases. Strictly speaking, the combustion method of this type of product is closer to the atmosphere Stove

[0006] 4. In the infrared burner with integral structure design, there are still many porous combustion radiant plates and burner heads that are designed by adhesive bonding and sealing. If the porous combustion radiant plate is accidentally damaged and needs to be replaced, it needs to be disassembled Panels, burners and other parts can only be replaced, resulting in high maintenance complexity and low maintenance efficiency

[0007] 5. The infrared burner with integral structure design cannot form a completely closed structure between the infrared burner and the panel (or liquid receiving plate), so during the cooking process, it is very easy to cause stains to flow into the stove from the gap between the two inside, and then flow into the interior of the cabinet, affecting the user experience

[0008] 6. The infrared burner adopts a split structure design. The premixing chamber is basically designed with a cast iron structure. The inner wall of the injection tube has a low finish, which affects the ability of one injection, resulting in the gas-air cannot be completely premixed, and the flame is elongated. Decreased thermal efficiency

[0009] 7. The infrared burner adopts a split structure design, and the premixing chamber directly adopts an atmospheric furnace chamber structure. The parameters of the ejector tube and the chamber cannot meet the design requirements, resulting in the inability to achieve complete premixing of gas-air, and the flame is elongated. Decreased thermal efficiency

[0011] 9. For the mainstream infrared burners currently on the market, the ignition needle and ion needle are generally placed in the center hole of the furnace head, and they are all connected by screws. If the porous combustion radiation plate is accidentally damaged and needs to be replaced, the screws need to be removed and loosened Ignition needle and ion needle, if the screws are corroded, it will cause high maintenance complexity and low maintenance efficiency

[0012] 10. The mainstream infrared burners currently on the market are stamping burners and die-casting burners. Due to the limitations of stamping and die-casting processes, most of the ejector tubes and furnace chambers are welded or screw-fixed. , resulting in many processing steps, complicated processing technology and high processing cost
