This paper is Although air fryers, whose demand has soared recently, are exposed to fire risks and cause fires continuously, it is difficult to identify the cause of such fires, so it is a study to find out the risk of fire through experiments.
For experiments, it was designed based on the cases of experiments and fire investigation reports in KS C IEC 60335-1, the standard for air fryer.
The air fryer reaches its maximum temperature within 10 minutes of initial operation.
25.2°C above allowable temperature in lower specification of Power code.
It has been confirmed that the temperature difference of the coil heater is up to 110.2°C, even if it is the same type.
It has been confirmed that internal temperature increases when sealing the air fryer outlet, accelerating deterioration and aging, which poses a high risk of internal Open circuit.
In the case of cooking oil, it is not a direct cause of ignition, but it is believed to have an effect of expanding fire.
In the case of internal oil stain, it is deemed that there is sufficient possibility of ignition in contact with the hot wire.
In the case of equipment abnormal conditions, it has been confirmed that the fire hazard is high by checking the possibility of ignition in food before the operation of the internal fuse.
When igniting inside the basket, the air outlet on the rear side has been identified as a vulnerable area, and if the passage of the outlet collapses, the thermal phenomenon in the air fryer is expected to increase further.
When measuring the amount of heat generated by the motor, it was found that the difference in temperature between normal and abnormal operation was 50.7°C and 116.1°C respectively, which is 2.29 times greater.
When the current is measured during operation of the air fryer, it is found that the current is about 30% higher than the normal operation.
In the tracking experiment of thermostat, it was confirmed that a small amount of saline water was immediately contacted or continuous flame discharge occurred.
After checking the contact point of the thermostat through the actual microscope, it was confirmed that the entire contact area was damaged after the tracking experiment.
In the accident reenactment experiment, the overall progress of the air fryer was checked and the factors of the air fryer fire were considered.
Preferential judgment shall be made on the point of ignition and the top/bottom judgment on the inside/outside of the air fryer as a result of the fire investigation.
The presence or absence of food inside the basket should take into account carelessness in use and check the operation of the air outlet, fan and thermostat when determining the upper ignition point.
The possibility of igniting device plastics or combustibles should be considered as internal heat accumulator may cause fire due to internal heat accumulator in the event of upper problem, and heat from internal heat wires is not circulated during motor failure and restraint.
In case of a lower problem, check the external heat collection problem, especially when placed on the electric stove, check the pattern of carbonation in a circular shape of the lower part and short circuit in the power line.
If it is ignited from the outside, it should be checked that the internal damage is good due to the high amount of heat emitted from the outside.
In the event of a fire caused by an external flame while power is connected, no electrical singularity is found inside the device because the power line is first shorted.
In the case of an air fryer fire as a result of the above, the following conclusion can be reached.
Self-performance and initial operation of the coil heater can affect the temperature of the coil heater, given that the maximum temperature is reached within 10 minutes of operation and that a fire occurs early in the use of the air fryer in the case.
Assuming carelessness in use, Decorating due to internal heat accumulator when sealing the air outlet, especially since the power line is higher than the allowed temperature in the specification, the deterioration and deterioration of the insulated wire can be accelerated, resulting in the risk of open circuit.
Oil stain affects the initial temperature rise of the coil heater, resulting in a high risk of fire during initial operation
In the case of paper foil, it is likely to be a direct source of ignition as a catalyst, leading to a fire in the form of a smoked fire.
Experiments assuming abnormal behavior have a high risk of fire due to mechanical problems, and the current also has an effective value of 220.5 mA at 170.1 mA, which requires approximately 1.3 times the current, which affects motor overheating and temperature rise
Accident re-enactment test results in a fire when air is introduced due to melting and damage to the vulnerable parts of the air fryer
Air fryers, in particular, should be careful as they continue to recur even after the fire is put out.
It is thought that many experiments and studies should be conducted in order to derive fire identification techniques for air fryers as a result of this.
