Gas stoves are a must-have kitchen appliance for every family. Safety features are especially important because they need to be connected to natural gas. Of course, when consumers buy gas stoves, in addition to the safety performance, the ignition method and the material of the burner are also important criteria for judging the quality of the gas stove.
Embedded stove should pay attention to safety performance
At present, the gas stoves on the market are mainly divided into desktop and embedded. According to the salesperson of an electric appliance store on Hubin South Avenue, the appearance of the general desktop stove is not as good as that of the embedded stove, but the thermal efficiency of the desktop stove is generally due to the wind and other reasons. It is higher than the embedded stove. "However, when the embedded stove is installed, the bottom case cannot be completely isolated from the outside air. It is necessary to open a hole of about 80 square centimeters in the cabinet to prevent the cabinet from being trapped due to sealing, which may cause accidents," the salesperson reminded.
The biggest difference between the embedded household gas stoves on the market is the stove panel materials, mainly stainless steel and glass, and some products choose enamel and other materials. Among them, the stainless steel material is strong and resistant to collision, but the surface gloss will be worse after long-term use; the glass material is more beautiful, corrosion-resistant and wear-resistant, but its heat resistance is not as good as that of stainless steel. If it is improperly installed and used, it will cause bursting. The phenomenon occurs.
It is worth noting that the embedded household gas stove must have a flameout protection safety device, so consumers must pay attention when purchasing. Due to the special use conditions of the embedded gas stove, the accidental flameout phenomenon is more likely to occur during its use, and the flameout protection safety device will play a very good protection role.
Whether the igniter is good or bad determines the ignition success rate
The ignition mode of gas stoves is mainly divided into piezoelectric ceramic type ignition and electric pulse type ignition. Piezoelectric ceramic type ignition is mainly applied to some old-fashioned desktop gas stoves. Now, better gas stoves no longer use this kind of ignition. The way is.
The electric pulse ignition method requires a battery to be installed at the bottom of the gas stove, and its ignition success rate is extremely high, generally 100%. Because it only needs to twist the button once, it can continuously eject the spark until it ignites. “The most critical component of the gas stove ignition system is the igniter. The ignition with strong ignition and crisp sound can ensure the success rate and service life of the stove ignition. Therefore, consumers must manually switch the test several times when purchasing. Listen to the sound. If it is an electric pulse ignition switch, the human body should have no electric shock when touching the metal parts of the stove," the salesperson said.
Generally qualified cooker, the ignition switch has a continuous service life of more than 6,000 times, and the cock is still airtight. The number of inferior product igniters is less than 2,000 times. In general, if the qualified product is ignited 10 times continuously, the number of ignitions shall not be less than 8 times, and all fire holes shall be ignited in 4 seconds.
Copper burner heat quality is best
Consumers should determine the domestic gas stoves with different heat load values ​​according to their own living habits. According to the actual use effect, consumers should choose a single burner design product with a heat load ranging from 3500W to 4000W. “The gas stove is good, the key is the burner. The burner has the name of “the heart of the stove.†As the core component of the stove, the cost of the burner accounts for 1/3 of the total cost, and the rust-proof burner and forged copper The fire separator can guarantee the thermal efficiency of combustion and long service life. Under normal circumstances, the heavier the burner, the better the material is copper. Because copper has good thermal conductivity, good heat dissipation, high thermal efficiency, and is not easy to produce tempering. The aluminum alloy has poor thermal conductivity, poor heat dissipation, and reduced thermal efficiency, which is easy to cause tempering, and the carbon monoxide content is relatively high when burned," said the salesperson.
Consumers can turn on the gas stove switch when purchasing, observe the flame of the combustion chamber, and the outer flame should be light blue when burning. After ignition, adjust the flame size control knob. The large and small fires should be level and the combustion is stable. Even if it is adjusted to the minimum state, or the valve is closed, it should still burn normally, not jumping, not extinguishing, and not tempering.
