Common sense of using electric heating

Using electric heaters in winter can keep the room warm. In order to keep the indoor temperature suitable for human body, the general temperature should be 17 ~ 19℃, 18 ~ 20℃ for children's room and 14 ~ 16℃ for bedroom. At present, most electric heaters have fixed time and fixed temperature control. When the greenhouse reaches a suitable temperature, stopping heating can reduce unnecessary waste of electric energy.

There are many kinds of household electric heaters. Please choose the appropriate model according to the purpose. Local greenhouses can use reflective, while all greenhouses can use convection to warm every corner of the room through natural convection of air. There is also a fan type that uses fan motors to force convection of warm air. In addition, there are household heaters that use kerosene as fuel. However, special attention should be paid to safety when using the heater, especially if there is a baby at home, so as to avoid scalding accidents.

2. Daily maintenance of electric heater.

Heat dissipation: In order to make the electric heater play a better heating role, make the machine work normally and prolong the service life, try to make the position of the electric heater conducive to air circulation and heat dissipation.

Cleaning: it is best to use a soft cloth, scrub with household detergent or soapy water, and do not use solvents such as gasoline and toluene to avoid damaging the shell, affecting the appearance or rusting.

Collection: When the electric heater is not needed in warm weather, it should be cleaned, dried and stored. Don't store it in a humid environment, but stand upright in a dry place for use next year.

Talk about the correct use and maintenance of oil-filled radiator heater, because this thing is not used correctly, there will be security risks.

Oil-filled radiator heater is popular for its large heating area and effective indoor temperature rise. The heating principle and electrical control of this heater are different from other types of heaters, such as halogen heaters and electric ovens. Many consumers will not use it correctly, so the method of use is very important.

A, the correct use of temperature controller

The oil-filled radiator heater has no thermostat, and the surface temperature of the heater shell can be adjusted at will (below 1 10℃). During normal operation, the thermostat cannot always be set at the highest grade, otherwise, when the working temperature of the heater surface is close to 1 10℃, the thermostat is not easy to operate, and working at high temperature for a long time will burn out the internal devices or damage the protection. Therefore, when using the oil-filled radiator heater for the first time, the heater should be set in an appropriate position. When adjusting, first turn the thermostat knob clockwise to the maximum position, turn on the two-speed power switch, the whole machine is in the maximum output state, heat for about 5 minutes, and gently pat the upper surface of the shell with the back of your hand. If the temperature is appropriate, turn the knob slightly counterclockwise until there is a crisp contact bounce sound, and at the same time, the power indicator light on the power switch goes out, and then turn it clockwise for a small angle to prevent the contact from closing. After setting the temperature in this way, the heater can provide people with a satisfactory temperature. When the surface of the shell is slightly hot, the temperature is about 85℃. When the temperature of the heater shell is higher than the set temperature, the thermostat will automatically cut off the power supply to stop heating, and the heat stored inside will continue to be released. When the surface temperature drops 15℃, the thermostat contact will automatically close and be electrified to raise the temperature. When the shell temperature is higher than the set temperature, it will automatically turn off the power supply and stop heating. This cycle keeps the temperature constant.

Second, the correct choice of power switch

The oil-immersed radiator heater adopts two sets of sealed cathode electric heating tubes as heating elements, and the two sets of electric heating tubes are correspondingly provided with two-level selector switches. Common heaters on the market are 1500W and 2000W w. When waiting for the line to allow, the correct selection of power gear can save electricity and reduce the line load. When the heater is turned on or the indoor temperature is low, turn on the two-speed selector switch at the same time, and the heater will heat up quickly. When the working temperature of the shell surface reaches the set temperature point, the thermostat will automatically cut off the power supply. At this time, you should choose 1 or a power of 2. When the thermostat is reset and powered on, it heats with low power to gradually increase the indoor temperature.

Third, pay attention to keeping the room airtight.

The oil-filled radiator heater increases the indoor temperature in the form of air convection, and the indoor temperature affects the on-off of the power supply. Good indoor sealing, short heating time and long heat dissipation time after the room temperature rises, thus saving electricity.

Fourth, no reporting.

The heater works normally, and the surface temperature of the shell is high, which is generally set at about 90℃. The temperature control of the heater depends on the temperature-induced deformation of the thermostat metal sheet in the mask. If the periphery of the heat sink is wrapped and covered for baking clothes, the temperature of the covered heat sink will be significantly higher than the temperature felt by the bimetal in the plane, which will easily scorch the clothes and may lead to the damage of the heat conducting elements inside the heater shell. Five, it is strictly prohibited to reverse or put down the electric heater.

The heater shell is equipped with special heat transfer oil, which has a certain internal pressure after heating. In order to ensure that the internal pressure is lower than 0.2Mpa in normal use, the amount of heat transfer oil is about 70% of the total volume, and the internal space is large. Inverted or put down, the internal heating pipe is exposed to the oil level. In this case, electric heating may lead to overheating and cracking, thus damaging the heating pipe. In this case, you must pay attention to it when using it.

3. How to place the oil-filled electric heater

The oil-filled electric heater must be placed directly and cannot be inverted. Because the oil-filled electric heater heats the heat-conducting oil around the heating element through the heating tube at the lower end, the heat-conducting oil flows in the conduit to transfer heat. If you turn it upside down, flat or inclined, it will cause empty burning to burn out the heating tube.

You can't cover anything on the electric heater.

The electric heater is a constant temperature heater. Because of its high surface temperature, the surface of the electric heater cannot be covered with anything, otherwise it will be burned because the heat of the electric heater cannot be dissipated in time. When using a special dryer to dry wet clothes, be sure to wring out the water to avoid danger caused by water drops in the control box of electric heater (except waterproof ones).

5. What are the requirements of electric heater for power supply?

When using electric heaters, three hole socket with grounding wire whose technical indicators meet the standard must be used. Never switch to a two-hole socket without a ground wire, because it is easy to generate static electricity, and sometimes it will feel like an electric hand, which is more dangerous. In addition, the socket should not be located directly above the electric heater to prevent the heat from rising and burning out the power supply. Third, whether there are electrical appliances that are easy to cause sudden changes in current and are frequently used, such as electric welding machines and impact drills. It is easy to damage the electric heater, so be careful. It is best to use a patch panel with over-current protection device, or choose a regulated power supply.

Description of electric heater of right upper oil heater: The utility model relates to a heater, which comprises an oil heater main body, and the oil heater main body comprises a heating sheet group and an oil heater heating tube. The far-infrared heating tube and the emission plate are installed in the mask fixed on one side of the oil heater main body, and the oil heater and the far-infrared heating tube are electrically connected with corresponding control circuits on the control panel with cooling holes installed on the mask. Because the oil-filled electric heater and the far-infrared heater are integrated and controlled by the control circuit respectively, the oil-filled electric heater, the far-infrared heater and the two heaters can work independently, have the advantages of two heaters, can meet different use requirements, and make the performance of the heaters more perfect, practical and effective; At the same time, it can also reduce the packaging volume of products, save materials and reduce costs.
