At present, there are four types of air intake methods for gas stoves on the market: upwind, downwind, side inlet and full intake.
Downward air type: This type of cooker is copied from the imported cooker. It increases the heat load and burner in accordance with the cooking habits of the Chinese people. The foreign product is required to open the cabinet or rely on the larger cabinet. The gap is used to supplement the secondary air required for combustion, and is used for leaking gas, inevitable discharge during ignition, and small heat load design. However, domestic users seldom know that the cabinets are opened, resulting in insufficient combustion, high concentration of yellow flame and carbon monoxide, and once the gas leakage is large, it may cause ignition deflagration, causing the glass panel to burst.
Upwind type: This type of cooker improves the shortcomings of the first type of cooker, raising the burner above the countertop, hoping to enter the air from the gap between the burner and the drip pan. However, when the part of the fire has formed a high temperature zone, the cold air is heated and expanded, so that it cannot enter the furnace head. Therefore, the secondary air is still not effectively replenished, and the problem of high yellow flame and carbon monoxide concentration cannot be solved at all. This kind of structural design, the thermal load can not be designed too large, more than 3.06 kWh yellow flame is very powerful, low thermal efficiency, not in line with the Chinese people's demand for fierce fire, and the high burner makes the appearance of the cooker greatly reduced, but can Reduce the burst rate of the glass panel. Side inlet type: This type of stove is equipped with an air inlet in the relatively low temperature area of ​​the panel. When the combustion reduces the air in the housing to form a negative pressure, the cold air is sucked into the housing along the inlet of the air inlet, not only Ample primary air and secondary air required for combustion solve the problem of yellow flame, the concentration of carbon monoxide is also greatly reduced, and the leaked gas can also be discharged from this inlet, even if the gas leaks ignited and deflagrated, the airflow It can also be discharged as quickly as possible from the air inlet to quickly reduce the internal pressure and prevent the glass panel from bursting. At the same time, cold air enters the furnace through the air inlet, which also greatly reduces the temperature of the countertop glass. The stove has a thermal load of up to 3.8 kW.
Full air intake type: This type of cooker not only has an air inlet on the chassis, but also has an air inlet between the burner and the liquid receiving tray, so that not only sufficient primary air but also secondary air required for combustion is provided. The problem of yellow flame is solved, the carbon monoxide content is also greatly reduced, and the tempering caused by the door of the switch door is avoided, thereby reducing the probability of bursting of the glass panel. Because this type of cooker adopts the characteristics of the upper air inlet type and the lower air intake type cooker, it not only maintains the high heat load of the cooker, but also has a large flame adjustment range, which conforms to the advantages of the cooking habits of the Chinese people, and also greatly reduces the specific inner and glass panels of the cooker. The temperature effectively prevents the glass panel from bursting. At present, the "Haihua" brand and other gas cookers on the market use full-intake glass panels.
At present, most of the embedded glass panel cooktops on the market are in the first three forms. If the quality of the product is not properly installed or improperly installed, it is prone to insufficient combustion, such as excessive CO, yellow flame, low firepower, high panel temperature, and even glass explosion. phenomenon. Therefore, consumers must purchase brand-name products in large shopping malls or building materials cities with good reputation. When installing, remember to punch holes in the cabinet to ensure smooth airflow.
At present, most of the embedded glass panel cooktops on the market are in the first two forms. If the quality of the product is not properly installed or improperly installed, it is easy to appear that the combustion is insufficient, the yellow flame, the temperature of the shell and the panel are high, the firepower is not strong, and the glass panel is exploded. . Therefore, consumers must purchase brand-name products, and remember to punch holes in the cabinet to ensure airflow.
The safety protection system includes various mechanical and electrical protections. The five major components include: safety gear, speed limiter, door lock, buffer, rope gripper and uplink overspeed protection. In order to effectively avoid frequent elevator accidents, we should do a good job in elevator safety devices and inspection, eliminate hidden dangers and ensure elevator safety.
