Downward Air Type: This cooker model draws inspiration from imported designs but has been adapted to better suit the cooking habits of the Chinese population by increasing both the heat load and the size of the burners. Foreign models typically require opening the cabinet or relying on larger gaps to allow for secondary air intake necessary for combustion. These designs also account for gas leakage during ignition and smaller heat load requirements. However, many domestic users are unaware of the need to open the cabinet, leading to incomplete combustion. This results in issues like yellow flames and higher concentrations of carbon monoxide. In the event of significant gas leakage, there’s a risk of ignition deflagration, which could potentially cause the glass panel to shatter.
Inlet Type on Kitchen Appliances: To address the shortcomings of the first type, this cooker elevates the burner above the countertop, aiming to draw air in through the gap between the burner and the drip pan. Despite this modification, when the fire creates a high-temperature zone, the cold air entering gets heated and expands, preventing effective secondary air intake. Consequently, problems such as yellow flames and elevated carbon monoxide levels persist. This design limits the thermal load to around 3.06 kWh, producing a strong but inefficient flame. The low thermal efficiency and lack of a robust flame do not align well with the Chinese preference for intense firepower. Additionally, the raised burner affects the overall aesthetic of the appliance, though it does help reduce the likelihood of the glass panel bursting.
Side Inlet Type: This cooker model features an air inlet located in a relatively cooler area of the panel. As combustion occurs, it reduces the air pressure inside the housing, creating a negative pressure that pulls cold air into the housing via the air inlet. This ensures an adequate supply of primary and secondary air for combustion, significantly reducing yellow flames and the concentration of carbon monoxide. Gas leaks can also be vented through this inlet, minimizing risks even in cases of ignition deflagration. The airflow helps expel gas quickly, lowering internal pressure and preventing glass panel explosions. Furthermore, the cold air drawn in through the inlet cools the countertop glass considerably. With a thermal load of up to 3.8 kW, this design offers a more efficient and safer cooking experience.
