Gas stoves used to produce burning black (blackened) the bottom of the pot, is not the flame when the gas stove is yellow instead of light blue "translucent" state? If so, it should be gas stove gas burning mixture of air is too small, resulting in incomplete combustion of smoke to the bottom of the blackened. Approach, you can take a look: in the stove gas valve switch (stove table below) on the gas nozzle (copper) and iron burner (stove head) where there should be a shape similar to the "Butterfly" butterfly Throttle ", it is possible to cover the combustion head for the inlet of the mouth, if covered too much or all covered, it will result in the use of air supply is insufficient, resulting in the phenomenon of mixing is not enough to make the flame yellow , At the same time produce more flue gas (incomplete combustion); sometimes it is also possible because the throttle is too large and the air into the combustion head too much burning flame "left" stove, the top of the flame " Shape "change" sharp "phenomenon, so sometimes cause the phenomenon of flameout, but this situation is relatively rare. For incomplete combustion, the smoke generated at the end of the black pot, you can put the butterfly valve cover the combustion head into the air space to adjust a little larger, (left and right flip butterfly valve on a protruding lever can be Adjust the throttle opening size), until the flame blue light translucent state and combustion "powerful" can be. To prevent the gas stove to burn the bottom of the black pot method Under normal circumstances, gas stoves for the two burner, then you need to smoke hood has two air inlets to correspond to two gas stove stove, in order to achieve better absorption of fumes effect. All range hood products are top-suction, and the use of "double inlet" design to correspond to two gas stove stove, which is equal to expanding the range hood suction area around the negative pressure, when the fumes rise, to be more Absorb soot quickly and more completely to allow fumes to be discharged outdoors. Due to the use of smoke exhaust, fumes have not yet had time to spread to be inhaled into the exhaust pipe below, so do not worry about oil is inhaled, the general will come to buy the most valued of this product is exactly this feature. The entire stove with intelligent control, simple operation, according to different needs, the amount of smoke fumes divided into third gear, are free to choose, to avoid waste. Sink down the stove slightly lower than the suction outlet, can well achieve the effect of wind and heat, energy conservation. Shuaikang gas stove repair phone is mainly on the cleaning process can use the correct method, but also have some demolition skills, so understanding of this area is also of some significance, so as to achieve better results, so that Will not easily occur in the process of using prone to failure, according to the oil on the glass with a newspaper, rag hard to clean, available alkaline scrubbing in the form of wiping, and then reuse sodium hydroxide or dilute ammonia solution in the glass On the last half an hour and then wipe the cloth, the glass will become bright and clean. Mainly on the cleaning process can use the correct method, and disassembly have some skills, so understanding of this is also a certain significance, so as to achieve better results, so it will not easily occur in The use of the process prone to failure, in accordance with the oil on the glass with a newspaper, rag hard to wipe clean available alkaline scrubbing wipe the form, and then reuse sodium hydroxide or dilute ammonia solution on the glass, more than half an hour Then wipe the cloth, the glass will become bright and clean.
