Hanging air conditioner burns into coke for a few minutes, how to prevent self-ignition of air conditioner

Mr. Yu, who lives in Cixi Yudong, thinks that there is still some fear. The hanging air conditioner in his home suddenly caught fire during the use. In just a few minutes, the air conditioner burned into coke. Fortunately, it was discovered earlier that it did not cause even greater losses.

However, Mr. Yu is very dissatisfied that he contacted the customer service twice, but the other party only gave registration and has not responded.

The night-mounted air conditioner suddenly caught fire

Mr. Yu bought a hanging air conditioner called Wellcome, and the manufacturer is also in Cixi. This air conditioner was bought in 2005 and it has been counted for some years. “It’s been good before, and there’s nothing wrong with it.”

The air conditioner is placed in Mr. Yu's mother's bedroom. "Our family lives in the countryside. The frequency of air conditioning is usually not high. It is also used when the summer is very hot. Besides, the elderly are also more economical, and it will be opened when it is particularly hot. "Mr. Yu said,

It was very hot on July 7. At about 10 o'clock in the evening, Mr. Yu was watching TV, and he almost fell asleep. He suddenly heard the mother who was living on the first floor yelling: "The fire is on fire." Mr. Yu lives on the second floor and he runs quickly. Looking down, the right side of the air conditioner is constantly smoking, the smoke in the room is rolling, giving a pungent smell, the situation is very critical.

Or Mr. Yu is calm, his first thought is to cut off all the power at home, but the fire is still increasing. The electric appliance caught fire and could not be drained with water. So he quickly found a piece of cloth, covered it in the air conditioner after immersion in water, and the fire was slowly extinguished.

However, in just a few minutes, the right side of the air conditioner has burned coke. Mr. Yu said that at that time, the power plug was more than 1 meter away from the air conditioner, and it could not be caused by electric leakage. The ignition point was located inside the air conditioner and should be burned from the inside.

The next day, he called the company's customer service phone, the other party said that their company is no longer producing such hanging air conditioners, but they will register Mr. Yu's situation. However, there was no audio after that.

On the third day, Mr. Yu called the customer service again, and the other party responded the same, and no staff members contacted him. Mr. Yu was very dissatisfied and called 12345 to make a complaint.

Factory: still negotiating

Yesterday, the reporter contacted the after-sales service department named Ningbo Wellcome International Industrial Co., Ltd., a staff member surnamed Jiang said that he would reflect the situation upwards.

Subsequently, Mr. Yu told reporters that shortly after the reporter finished the call, there were maintenance personnel who went to his home to view and took photos, but they did not answer how to solve them. "I have never encountered this kind of situation and I don't know what kind of request. If they are still producing this kind of air conditioner, just change one for us. But they are no longer produced, just wait. Look at how they handle it," said Mr. Yu.

After that, a staff member named Hu of the company contacted the reporter and said that they were communicating with Mr. Yu. "At present, our company mainly produces refrigerators, and air conditioners have been discontinued. The service life of air conditioners is generally 8 years, and Mr. Yu's air conditioner has been used for 13 years and has passed the service life. As for the solution, we will consume Negotiations," said Mr. Hu.

How to prevent self-ignition of air conditioners in summer?

With the arrival of the air-conditioning season, the most terrible problem is self-ignition. What is the cause of self-ignition of air conditioners? How can I avoid it? The reporter interviewed a senior air conditioning maintenance expert.

He first analyzed the reasons for the spontaneous combustion of air conditioners:

The service life of air-conditioner wall-hanging machine is generally about 8 years. After 5 years of use, the circuit inside the internal machine may be aging, the insulation layer may be destroyed, and leakage may occur. When the current is too high during operation, high temperature may occur, causing sparks, resulting in air conditioning. Self-ignition. Therefore, when the air conditioner is used for a long time, it is best to find a professional master to check the repair.

Long-term operation of the air conditioner can also cause the motor to burn out. Inside the air conditioner, the inside of the machine is driven by strong electric power to the motor to drive the rotation of the bearing. The bearing drives the rotation of the fan, and finally the cold amount is delivered to the room. When the air conditioner is operated for a long time and the internal motor reaches a certain temperature, it will cause the internal insulation layer to burn out, causing leakage and causing sparks.

Another possibility is that the wiring of the motor is connected incorrectly, causing the motor to burn out.

In response to air conditioning problems that may cause fire, he recommends the following measures:

1. The height, direction and position of the air-conditioning installation must be conducive to air circulation and heat dissipation, and pay attention to keep a certain distance from combustibles such as curtains. When the air conditioner is running, avoid too close to other items, and do not cover the air conditioner.

2. When the power is suddenly turned off, the power plug should be unplugged. Wait a few minutes after power-on and then turn on the power. Air conditioners must use special power outlets and wiring, and cannot be used with lighting or other household appliances. The wire current carrying capacity and the meter capacity are sufficient, and the plug is in close contact with the electrical components.

3. The air conditioner should be equipped with a one-time fuse protector to prevent the temperature from rising after the capacitor breakdown, resulting in a fire. The fuse capacity should be suitable. It should not be replaced by wire or copper wire.

4. The air conditioner should be regularly maintained, regularly clean the condenser, evaporator, filter, heat exchanger, wipe off the dust, prevent the radiator from clogging, and avoid fire hazards.
