1. Oil accumulation. If you cook frequently, the oil fume will accumulate a lot of grease and accumulate inside the machine, which is easy to catch fire at high temperature.
2. Cleaning is not timely. The range hood needs to be cleaned frequently. If it is not cleaned up in time, there will be more and more oil pollution, and oil pollution will also form a fire when it gathers in one place. Others do not pay attention to cleaning the gaps. If they are not cleaned for a long time, dust or oil stains will accumulate. If the situation is not good, it will lead to faults, short circuits and fires.
3. Mechanical failure. The range hood will also have some mechanical failures, such as battery short circuit and circuit failure, among which circuit failure is one of the most likely failures to cause fire.
4. Improper installation. If the range hood is improperly installed, too close to the fire source or the cooker is unstable, it will also cause important items to catch fire. For example, the installation angle is incorrect, and the base or plug falls off, which causes the machine to vibrate, thus causing an accident.
5. Other reasons. Although some users use it according to the instructions, they use the wrong high-energy charged appliances (such as conditioning machine and juicer) to connect the range hood, which leads to failure.
In short, if you want to avoid the fire of the range hood, you should first pay attention to keeping it clean and cleaning it regularly. If the machine is found to be faulty, it should be repaired or replaced in time. Thirdly, the base must be installed firmly, safely, insect-proof and waterproof, and the maintenance personnel must have professional knowledge and skills to ensure the safety and reliability of maintenance. The best preventive measure is to turn on the range hood when using the cooker, and make sure that all electrical appliances are turned off before leaving home to avoid accidental fire.
