In the cold winter, the heater is a household appliance that can bring warmth to everyone. The electric heating oil heater is a type of electric heater. Because a few people do not know the structural characteristics and safety precautions of electric heating oil heaters, and the quality of electric heating oil heaters is poor. Fire and explosion accidents sometimes occur with electric heating oil heaters. This is not alarmist. On March 3, 1993, a case of an electric heating oil heater causing injuries due to an explosion occurred in Qingdao City, Shandong Province, which shocked the whole country and attracted widespread social attention. But not all electric heating oil heaters will have this problem. The editor will introduce it to you below.
1. What is electric oil heater
Electric oil heater, also called oil-filled heater, is a safe and reliable space heater that is currently popular. This kind of heater is generally equipped with a bimetal temperature control element. When the oil temperature reaches the set temperature, the temperature control element will automatically disconnect the power supply.
The biggest feature of this heater is that it dissipates a large amount of heat. Even in the event of a sudden power outage, it will maintain a certain temperature for a long time. At the same time, it does not produce any harmful gases and is harmless. Electrical appliances operate noisily. The surface temperature of electric oil heaters is relatively low, generally not exceeding 85°C, and will not cause burns even if it touches the human body. It is suitable for heating in places where the human body may be directly touched.
2. Characteristics of electric heating oil heater
Structural characteristics of electric heating oil heater: The structure of electric heating oil heater mainly consists of three parts: front cover, radiator assembly body and foot. Partially assembled. The front hood is equipped with switches, indicator lights and thermostats. There is a box for placing the power cord at the middle and lower part. There is a handle above the front hood for easy movement during use. The radiator assembly is composed of multiple units. The heater pieces are connected into a sealed cavity, filled with heat-seeking oil, and the lower part is equipped with a tube-voltage electric heating element. There is a unscrewable cover on the upper part, and the caster part has sufficient temperature. The temperature will rise even more, the pressure will be greater, and it will not be delayed by the air, and there is also the risk of explosion.
3. Will the electric heating oil heater explode?
The so-called explosion occurs when the internal pressure increases to the point that the outer shell cannot bear it. It is indeed possible for electric heating oil to explode. This happened in Qingdao, Shandong Province. There are two general reasons: 1. Temperature control failure, excessive expansion of the heat transfer oil caused by excessive temperature; 2. There is moisture in the heat transfer oil. , caused by the vaporization of moisture after heating.
Now that oil prices have been rising, some manufacturers will use some impurity-containing heat transfer oil in order to make profits. Poor oil quality is also one of the causes of explosions caused by electric heating oil heaters; because electric heating oil heaters are heated by steel sheets. It dissipates heat, so the machine itself has many solder joints and is prone to oil leakage. In short, electric heating oil heaters have many safety hazards. The editor recommends that friends who want to buy an electric heater learn more about the relevant knowledge before deciding to buy it. Now the market has appeared Many alternatives to electric heating oil heaters, the new product heats up quickly, is environmentally friendly, and has no oxidation. It is a new type of environmentally friendly heating equipment. It has attracted a lot of attention when it was launched on the market because of its health, environmental protection, non-toxicity, non-oxidation and many other advantages.
IV. Precautions when using the electric heating oil heater
When using the electric heating oil heater, be sure to place it upright because it heats the surrounding thermal oil through the heating tube at the lower end. , which makes the heat transfer oil flow in the guide tube to transfer heat. If it is placed upside down, flat or tilted, it will cause air burning and burn out the heating tube.
When the electric heating oil heater is used for heating in the living room, it should be as close to the air convection position as possible, so that it is both warm and energy-saving. Since the surface temperature of the radiator-type oil heater can be as high as about 85 degrees Celsius when it is working, it should be kept away from people's heads when used for heating in bedrooms. If there are children at home, they should be placed in a place where children cannot easily touch them, or some protective facilities should be added around them to prevent children from being burned when playing.
It is important to note that electric heating oil heaters cannot be used in bathrooms. Although the switch of the electric heating oil heater has a plastic shield marked as waterproof, it is only waterproof against splashes and not against vapor, so it may be dangerous to use it in the bathroom.
Material selection: Key raw materials and electrical components such as: adjustable temperature control, thermal fuses, power cords, electric heating tubes, thermal oil, steel plates, etc. are all supplied by the best domestic suppliers, and all plastic parts They are all made of flame-retardant materials and meet all safety testing requirements. (Some manufacturers use good materials for certification, but use materials that do not meet the requirements in actual production. The steel plates will be thin 0.4MM or 0.45MM, plastics will be non-flame retardant, and electrical components will be used in underground factories. The quality cannot be guaranteed).
As can be seen from the previous introduction, electric heating oil tents will indeed cause explosions if used improperly. Therefore, if a friend buys electric heating oil tents, be sure to pay attention when using them. Keep it flat, otherwise there is a risk of burning. Also, you must buy electrical appliances with guaranteed quality, especially electrical appliances that have experienced accidents. You must be more cautious when purchasing them.
