every time the steam electric iron is used up, the remaining water must be emptied. If it is not clean, you can plug in the electricity to let the steam spray from the bottom plate. Otherwise, the water left behind will flow out from the bottom plate, and the minerals in the water will stick to the bottom analysis when heating next time, which will erode the bottom plate for a long time.
Never immerse an iron in water.
The steam electric iron is best stored upright, which can prolong the service life.
To make the iron durable for a long time, use the "automatic cleaning" function at least once a month to remove the scale accumulated in the iron and store it after it is completely dry.
proper use and maintenance of oil filled radiator
oil filled radiator heaters are widely welcomed for their large heating area and effective indoor temperature increase. However, the heating principle and electrical control of this heater are different from other types of heaters, so first-time users must read the instructions carefully and master the correct and safe use methods.
1. Use the thermostat correctly
There is no thermostat in oil filled radiator heater, so the surface temperature of the heater shell can be adjusted at will (below 12℃). When working normally, the thermostat should not always be set at the highest grade, otherwise, when the surface working temperature of the heater is close to 12℃, the thermostat will not act easily, and the internal devices will be burned and aged or the protection will be destroyed if working at high temperature for a long time. Therefore, when using oil filled radiator heater for the first time, the thermostat should be set in an appropriate position.
when adjusting, first turn the knob of the thermostat clockwise to the maximum position, turn on the two-speed power switch, the whole machine is in the maximum output state, heat it up for about 5 minutes, and gently pat the upper surface of the shell with the back of your hand. If the temperature is suitable, turn the knob counterclockwise slightly until there is a crisp sound of contact bouncing off, and at the same time, the power indicator light on the power switch goes out, and then turn it clockwise slightly to prevent the contact from closing. After this setting, the heater can provide people with 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 outward. When the surface temperature drops by 15℃, the contact of the thermostat will automatically close, and the temperature will be raised by electrifying. When the shell temperature is higher than the set temperature, the power will be cut off and the heating will be stopped automatically. This cycle, the temperature is constant.
second, correctly select the power switch
oil filled radiator heater uses two sets of sealed electric cathode heating tubes as heating elements, and the two sets of heating tubes correspond to two selection switches of two grades. At present, the common heaters on the market are set at 15W and 2W W. Under the condition of line permission, the correct selection of power gear can save electricity and reduce the line load. When starting to turn on the heater or when the indoor temperature is low, turn on the two selector switches 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, the power of the first gear or the second gear should be selected. When the thermostat is reset and powered on, it is heated with lower power to gradually increase the indoor temperature.
Third, pay attention to keeping the room airtight
oil filled radiator heaters raise the indoor temperature in the form of air convection, and the indoor temperature affects the power supply. Good indoor sealing, short heating time and long heat dissipation time after the room temperature rises, thus saving electricity.
Fourth, it is forbidden to cover
The heater works normally, and the surface temperature of the shell is high, which is generally set at about 9℃. The temperature control of the heater depends on the temperature sensing 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 obviously higher than the temperature felt by the bimetal in the plane, which will easily scorch the clothes, and may lead to the denaturation of the heat transfer oil inside the heater shell, the pressure increase, the hot oil leaking from the seal, and even the shell bursting, causing danger.
5. It is forbidden to turn upside down or turn down for electric heating
The heater shell is filled with special heat transfer oil, and there is a certain pressure inside after heating. In order to ensure that the internal pressure is lower than .2Mpa during normal use, the amount of heat transfer oil is about 7% of the total volume, and there is a large space inside. Inverted or put down, the internal heating pipe is exposed to the oil level. In this case, the heating with electricity may cause overheating and cracking, which may damage the heating pipe. In this case, we must pay attention to
six taboos for working-class people to buy electrical appliances
one taboo is "cheap". It is generally believed that working-class people should buy similar goods with lower prices when shopping because of their limited income. Some merchants also introduce some low-grade or even outdated goods as the "first choice" of the working class, which is actually a misunderstanding. Although there are many goods in the market that are worth more than their value, if you don't know how to take things only by price, you are likely to buy some goods with poor quality and price, and you will feel sorry when you use them.
The second taboo is to seek perfection. Many people easily make a mistake when buying electrical appliances, that is, to seek perfection. It is believed that the more functions of electrical appliances, the better. Of course, "all" is not a bad thing, if your budget is unlimited. However, it is generally inappropriate to ask for full functionality at a certain price.
three taboos "seeking foreign countries" Although China's industrial base has a certain distance compared with foreign developed countries, it is a fact that some products are not as good as foreign countries. But in many products, domestic products can compete with foreign products. However, when buying domestic products, you must buy "domestic products" or choose them with the help of knowledgeable people. The domestic prices of some miscellaneous brands may be tempting, but the quality will also be sad.
Four Taboos for "Bigness" We sometimes wonder why some people are so persistent in the pursuit of "Bigness". Like buying a stereo. Everyone says it needs high POWER. European and American manufacturers think that 5 watts per channel is enough. Chinese people insist on bigger and stronger power. As a result, every time they listen at home, they can only turn down the volume as low as possible, wasting power and money.
New products are often introduced in the electrical appliance market, and they all have some very exciting points. However, there is definitely a price for "trying new products". Because things are rare, new products are naturally profitable and expensive. With the development of the market, the price will fall into an acceptable position, so as a wage earner, it is best to be more patient and choose the right time to buy. In addition, the electrical appliance market is changing with each passing day, but the real technical breakthrough is not so easy.
six taboos for "beauty" here is not to say that buying electrical appliances should not be beautiful, but the use of electrical appliances is different from other commodities, it is not bought for decoration. If you decide to choose according to whether the appearance is good or not, you will go into a misunderstanding.
Precautions for using the washing machine
1. Take out coins and sundries from your pocket before washing. Clothes with metal buttons should be buckled, and the clothes should be turned over to prevent hard objects such as metal from damaging the washing tub and pulsator during washing.
2. The temperature of washing water should not be too high, generally 4℃ is appropriate, and the highest temperature should not exceed 6℃ (except for high-temperature disinfection washing machine with drum), so as to avoid scalding the washing drum or causing plastic aging.
3. After each washing, dry the accumulated water and water droplets inside and outside the washing machine with a dry cloth, and restore the knobs and keys on the operation panel to their original positions and place them in a dry and ventilated place.
4. Do not use strong alkali, gasoline, thinners and hard brushes when brushing the washing machine.
5. Some washing machines have oil holes on the main shaft sleeve of the impeller, and a few drops of engine oil can be added to the oil holes every two or three months.
how to charge the mobile phone
charge the mobile phone for enough time until the green indicator is on and the battery is fully charged. Generally, the battery of a medium-sized portable phone should be charged for at least 1 hours, and the battery of a small portable phone should be charged for 14 hours. The battery of mobile phone should be fully used. For new batteries or batteries that have been highly discharged, slow charging must be used at first to reach the maximum capacity, and then fast charging can be used
Key points for purchasing telephones
First, it depends on whether the telephone has a network access license number approved by the Telecommunications Administration Department of the Ministry of Posts and Telecommunications, and whether the validity period has passed. It should be noted that the model originally approved for network access and later cancelled for network access should not be purchased.
second, the quality inspection of telephone appearance technology: the plastic appearance of the casing is bright and clean without deformation. Put it on the desktop smoothly, firmly and without loosening; The fork spring and each button element are stuck, and the display function is clear and accurate. All functions are in accordance with the instructions.
3. Sound check: After the telephone is connected to an external line, the bell rings loudly, and the transmitted and received sound is clear without distortion or noise.
fourth, choose the functional model of the telephone according to your actual needs. The more functions, the better. Inapplicable functions are actually a waste. A telephone with many functions is often more troublesome to use and naturally more expensive. The usual functions are: pulse W audio dialing mode compatibility, redial of the last phone number, pause, hands-free, tone-off, etc. According to these functions and your actual needs, consider buying a model.
5. Pay attention to try the receiver handle to see if it is comfortable and comfortable to use. People use the telephone mainly to operate the receiver. On the one hand, its beautiful appearance is more important to see whether the receiver is well designed.
6. Pay attention to whether the color and shape of the telephone are in harmony with the environment. Handsets with beautiful shapes and colorful colors can often give people a beautiful enjoyment when placed in a proper position. When purchasing, we should fully consider the location to be placed and the harmony of the environment, so that the telephone is not only a modern communication tool, but also plays a role in decorating and beautifying the environment. Redial, pause, rabbit call, long-distance lock, adjustable ringtone, mute and so on. According to these functions and your usual actual needs, consider buying models.
Is inverter air conditioner suitable for you
Traditional air conditioners are also called fixed frequency air conditioners. Frequency conversion air conditioner changes the power supply frequency of compressor through frequency converter. The higher the power supply frequency, the faster the compressor rotates, and the greater the refrigeration (heat) capacity of air conditioner; otherwise, it is small.
The frequency conversion air conditioner has many unique advantages due to the new frequency conversion speed regulation technology:
1. The cooling speed is fast, and it is efficient and energy-saving. After the air conditioner is started, it is put into operation at a high frequency and power, and reaches the set temperature in a short time (generally 1/2 of the fixed frequency air conditioner), and then the air conditioner is operated at a low frequency to maintain the indoor set temperature. The inverter air conditioner runs at low speed for a long time, so it consumes less electricity, which can save more than 3% compared with ordinary air conditioners. Because of the realization of meta-level speed regulation, it can adapt to the refrigeration (heat) demand of a larger area. When used for heating in winter, due to the large "hot-cold ratio" (above 1.3), it can maintain a large heating capacity.
2. Low noise, small temperature difference and strong comfort. Because the inverter air conditioner adopts the advanced dual-rotor inverter compressor, it runs more smoothly and always works in a continuous low-speed state, avoiding the frequent start-stop noise of ordinary air conditioners, so the noise is very low, and the indoor noise can be below double decibels (the national standard is 48 decibels). Frequency conversion air conditioner adopts intelligent fuzzy control technology, which can keep the indoor memory always in the best state around the set value, so the room temperature fluctuates very little and remains relatively constant (the range of change is+.5℃), which makes people feel more comfortable.
3, ultra-low temperature and ultra-low pressure operation, long service life. When the inverter air conditioner is heating in winter, it generally adopts preheating mode, and it can start running normally even at a temperature of 1℃. Frequency conversion air conditioner can work normally in the range of 16 volts to 242 volts, so it has strong adaptability to wind fluctuation. As mentioned above, the inverter air conditioner avoids repeated start and stop, and works at low speed for a long time, so the service life of the compressor is longer.
4. Automatic defrosting and dehumidification account for the automatic defrosting of inverter air conditioners, which is controlled by a microprocessor and can strictly select the defrosting state. Dehumidification is also controlled by microprocessor, without cooling and dehumidification, and the dehumidification amount can reach more than 9 kilograms per day, which is no less than that of a special dehumidifier.
second, whether the inverter air conditioner is suitable for you
The advantages of inverter air conditioner are obvious. However, many consumers blindly seek novelty without fully understanding the performance of new products, resulting in misunderstanding of consumption. In fact, it is more suitable for the following situations:
1. Consumers in southern China. Take Guangzhou as an example. Many families use air conditioning in mid-March every year until October. After stopping for a month or two, winter heating began again. In this way, the air conditioner is used for about 1 months in a year, and the frequency of starting and stopping is less, and the effect of saving electricity is more obvious. In contrast, many areas in the north have perfect heating facilities in winter, and they are only used for about two months in summer, and most of the time they are idle. It seems that it is not worthwhile to spend one or two thousand yuan to buy inverter air conditioners, and it is more economical to use ordinary air conditioners.
2. It is suitable for areas with low or unstable voltage. For example, some mountainous areas rely on small power stations for power supply, and the voltage is low and unstable, so inverter air conditioners can be started as usual under low voltage. In large and medium-sized cities, the power supply voltage is relatively stable, even when the peak power consumption is rarely less than 2 volts, which does not bury the superiority of ultra-low voltage starting of inverter air conditioners.
3. Families with frequent people at home during the day, especially those with old people, children or patients, need constant room temperature and don't need to turn on and off the air conditioner frequently, so it is suitable to choose inverter air conditioner. For the general dual-employee family, adults go to work and children go to school during the day. Turn off the air conditioner when you go out and turn it on when you come back from work, so the advantages of the continuous adjustment function of the inverter air conditioner are discounted. What's more, it doesn't save electricity when it is frequently turned on. The development of inverter air conditioners in China started late, and it is only one or two years since it really entered the consumer market.
what is the best product? "Only what suits you is the best." This should be more than just the shopping standard for buying air conditioners.
