A high-quality induction cooker should have the function of automatic adjustment of output power, which can improve the adaptability of power supply and load. But some induction cookers don't have this function. When the power supply voltage rises, the output power rises sharply. When the power supply voltage drops, the power is obviously reduced, which will bring inconvenience to users and affect the cooking quality.
The quality of transistor induction cooker depends on the quality of high-frequency high-power transistor and ceramic glass-ceramic panel. When shopping, you must buy a single high-power transistor induction cooker with high speed, high voltage and high current, because it has good quality, excellent performance, high reliability and is not easy to be damaged.
The reliability index of induction cooker is generally expressed by MTBF (mean time between failures), and the unit is "hours". Quality products should be over 65,438+0,000 hours. The service life of induction cooker mainly depends on the service environment, maintenance and the service life of main components. It is speculated that the induction cooker will enter the failure period after three or four years of use.
Pay attention to its protective function. The selected induction cooker should have various protection devices, including small object detection, overheating automatic shutdown protection, over-voltage or under-voltage automatic shutdown protection, gas-fire automatic shutdown protection, 2-hour power-off protection, 1 ~ 2-minute automatic shutdown protection and audible and visual alarm display. Turn on the machine when purchasing, and check whether its protection function works normally according to the relevant detection methods in the user manual.
Random performance test Add cold water to the matching pot, turn on the power supply, press the "heating" button, and heat it at room temperature for 4 ~ 5 minutes until it boils, indicating that the induction cooker basically heats normally.
Specific preventive measures can be detected by the following methods:
First, thermal energy conversion is detected. Put the iron utensils on the induction cooker and turn on the switch. The bottom of the utensils should feel hot soon. When the induction cooker is working, there shall be no alternating current sound and vibration sound on the coil and other parts of the induction cooker except the normal sound of the cooling fan.
Second, check whether the automatic detection function works normally. This function is the automatic protection function of induction cooker, which is very important for induction cooker. Pay attention to the actual measurement when buying. The method is: remove the pot when the induction cooker is working, or put something that should not be heated on the stove surface, and observe whether this function can alarm or automatically cut off the power supply according to the detection time requirements of the induction cooker manual.
Third, the fan should run smoothly. Pay attention to turning the cooker upside down when buying, and shake it when not working. There should be no gaps between the fan blades and the shaft and between the shaft and the bearing. After electrifying, the motor should have no obvious noise or rubbing sound.
Four, the furnace surface appearance should be smooth without damage. The surface of induction cookers on the market is mostly heat-resistant crystalline ceramics. Pay attention to the flatness of the furnace surface when buying. If the furnace surface is convex, concave or inclined to one side, it will affect the normal production of thermal efficiency.
Question 2: What should I pay attention to when buying an induction cooker? I recommend three brands to you: Shang, Midea and Jiuyang. Don't think about the rest! How to choose the induction cooker The induction cooker adopts the principle of magnetic field induction eddy current heating, and the thermal efficiency is as high as 90%, which makes the ferromagnetic pot itself heat up at high speed to cook food, changing the traditional stove heating method, and has the advantages of high intelligence, no open flame, cleanliness, high thermal efficiency, rapid energy saving and so on. Some manufacturers with technical strength, such as Jiuyang, Midea and Shangpengtang, have successively invested in the R&D and production of induction cookers, and brands such as Jiuyang and Midea have emerged that are well received by consumers. Compared with the past, the induction cookers on the market have been greatly improved. Due to the adoption of single chip microcomputer technology and various sensing controls, the reliability of induction cooker has been significantly improved and the price has been gradually reduced. High-power induction cookers are only sold in 500 yuan, which is cheaper than computer microwave ovens and has good sales prospects. How can I buy a satisfactory induction cooker? Industry insiders remind consumers to consider the following aspects. The first is the brand. Choose a brand with strong technical force and high credibility. Products must pass CCEE China Electrical Product Safety Certification and ISO900 1 International Quality Certification. The second is power. At present, the power of induction cookers on the market is between 1500 W and 2600 W, which is divided into several grades. The higher the power, the faster the heating speed, but also more power consumption, so the price is expensive, so the purchase should be based on the number of people eating and usage. Generally speaking, families with less than 3 people choose about 1700W; 4~5 candidates1800 w; 1900W is suitable for 6~7 people; More than 8 people choose 2000W induction cooker. The third is the key component. The quality of induction cooker depends on the quality of high-frequency high-power transistor and ceramic glass-ceramic panel. There are indeed differences in induction cookers at different prices, and the quality of each brand is different. Consumers need to analyze specific problems when buying induction cookers, and can't distinguish quality and function by price. In addition, the price difference is also reflected in the motivation and material selection. Buying an induction cooker mainly depends on power, panel selection and IGBT (main power transistor, the most critical part of induction cooker). Generally, you should choose high-power imported panels with the same price. Jiuyang intelligent five-star 19D induction cooker with power 1900W is the flagship product of Jiuyang Company. The crystal ceramic panel imported from Japan's NEG company will never turn yellow. Germany Siemens IGBT (main power transistor), its excellent material selection determines its high-quality performance. The fourth is the protection function. The selected induction cooker should have various protection devices, including small object detection, overheating automatic shutdown protection, over-voltage or under-voltage automatic shutdown protection, gas-fire automatic shutdown protection, 2-hour power-off protection, 1~2-minute automatic shutdown protection and audible and visual alarm display. Turn on the machine when purchasing, and check whether its protection function works normally according to the relevant detection methods in the user manual. The fifth is modeling. An induction cooker with beautiful appearance can beautify the kitchen, so you can choose an induction cooker with beautiful appearance and light and harmonious color. The sixth is the price. We should "shop around" and have the same power supply and protection function. Chapter 3: The weather is getting cold, the gas price is rising, and the Jiuyang induction cooker is "hot". The weather is getting cooler this year. Master Wang, who lives in Dongshan District and loves to eat hot pot, will have a meal every three days. But his house is still a gas stove, especially now that the global oil price has risen, which has caused the domestic gas to soar. Now a can of gas in the Guangzhou market has passed 80 yuan, which is hard for Master Wang, who loves hot pot. Recently, Master Wang went to the shopping mall in the city and was happy when he came back. He bought a Jiuyang induction cooker. The electricity price is not expensive now, and electricity is much more cost-effective than gas. Master Wang is going to have dinner with some buddies recently. In fact, Master Wang has been longing for the induction cooker for a long time, but he has never made up his mind to buy it because of the high price and worry about the safety of electricity use. After the "Eleventh" Golden Week, manufacturers rushed to engage in promotional activities. Especially, Jiuyang saw that Carrefour was promoting Jiuyang induction cooker, and the price was only 199 yuan, which was cheap. Because there is a Jiuyang soymilk machine at home, it has been used for seven or eight years without problems, and I am also very reassured about Jiuyang induction cooker, so I bought it back. With the induction cooker slowly entering our ordinary life, the mysterious veil of induction cooker has been unveiled. It turns out that the unique intelligent design of smokeless and odorless naked induction cooker can not only set the temperature and time, but also automatically cut off the power supply, so there is no danger of using electricity at all. Master Wang is really relieved. Many consumers have had the feeling of seeing flowers in the fog for induction cookers. ......& gt& gt
Question 3: What should I pay attention to when shopping online for induction cookers?
1: It is not recommended to buy an ultra-thin machine. Now many businesses are pushing ultra-thin colors. The above are the tips of the merchants. The temperature rise in the ultra-thin machine is generally high, the heat dissipation effect is not good, and it is not durable for a long time, resulting in the damage of electronic components.
2. Pay attention to whether the panel is glass-ceramics. Nowadays, many manufacturers use ceramic panels (actually floor tiles) to save costs, which have poor temperature resistance and impact resistance. When you buy it, you can see from the position of the fan at the bottom of the machine that the ceramic panel is opaque and the glass-ceramics look a little red.
3. It is best to choose copper coil board, which is more durable, but there are many manufacturers using aluminum coil board on the market now. In order to save the cost (the technology of aluminum coil plate is mature now), this merchant will open it for you to see. As a consumer, you may not necessarily see the same color of enameled wires. Outsiders distinguish between copper coil plate and aluminum coil plate by hand feeling, and their weights are different. Copper coil plate is much heavier than aluminum coil plate.
4. The touch of the control panel is better than the button (long press of the button will cause problems). If you buy touch, you must buy a child lock function to prevent children from pressing it indiscriminately.
5. See if the plastic parts of the induction cooker are made of flame retardant materials.
6. Is there a cockroach-proof design at the position of the main board and the light board (some kitchens are used in a harsh environment, and there are many cockroaches, so it is easy for small cockroaches to climb in, causing damage to electronic components.
7. Consumers are unprofessional, so it is recommended to buy a big brand induction cooker.
Question 4: Matters needing attention in the use of induction cooker. Ye leye county
[Master] Ask Coconut leye county a question.
1, the induction cooker should be placed horizontally, not close to walls or objects, and the peripheral clearance should be at least 10cm.
2. Please use a special socket. Socket capacity 1300W induction cooker shall not be less than 10A, and induction cookers with 1600W or above shall not be less than 15A.
3. Please don't use the induction cooker in wet place or near the flame.
4. Don't heat or overheat the empty pot.
5. Don't put knives, forks, spoons, pot covers, aluminum foils and other metal objects on the flat plate, because they will get hot.
6. Please don't use paper, cloth and other items to pad the panel for indirect heating, so as to avoid scalding caused by too high temperature at the bottom of the pot.
7. Don't use an induction cooker on the carpet or tablecloth, so as not to block the air inlet or air outlet and affect the heat dissipation. Please add cardboard under the induction cooker when using.
8. Please avoid colliding with the ceramic panel. If cracks appear on the surface, immediately turn off the power supply and send it for repair.
9. Do not heat the food contained in the sealer, such as canned food, or the air in the container will explode due to thermal expansion.
10, please don't use aluminum foil paper directly or indirectly, so as to avoid the danger of burning aluminum foil paper red.
1 1. Never bring an induction cooker with a pot.
12. After cooking, the high-temperature heat generated by the pot will be conducted to the flat plate of the induction cooker. Do not touch the tablet immediately.
Question 5: What problems should I pay attention to when buying an induction cooker? Galanz, beautiful ~!
Electricity is convenient and cheaper than gas ~! Considering safety and reliability.
According to GB4706.29-92 standard, the design of induction cooker should meet the protection indexes such as temperature rise, overcurrent, overvoltage, undervoltage, surge impact prevention, electrostatic discharge impact, lightning strike, grounding protection, constant power, identification of large and small objects, and the circuit design should meet the creepage clearance of safety regulations.
Only by meeting these technical indexes first can we ensure the safety and reliability of the induction cooker in use.
Generally speaking, induction cookers that meet the above conditions are of good quality, high relative cost and high price in the market.
2) Consider the power factor.
At present, the mainstream power on the market is about 1800W (maximum firepower). According to the national standard, the actual power should be within the range of +5% and-10% of the nominal power. According to the nominal power 1800W, the measured power should be 1620 ~ 180.
As for the stable design of power, for professional induction cooker research institutions, it is generally designed according to the regional standard voltage and frequency. For example, in China, the grid voltage is 220V and 50Hz, so when designing the power supply, we should consider that 220V and 50Hz are the most ideal states (maximum values) of the power supply. When the power exceeds or falls below this range, the power should be deliberately reduced through the compensation circuit to achieve the purpose of protecting the whole machine and normal use.
The power should be stable for a long time, and the power cannot drift and drop after a period of use. The maximum power of induction cookers with most inferior components will not reach the national standard after half a year, far below the allowable range of nominal power. If the power drift is too large, all automatic cooking functions will be invalid.
3) Consider the voltage factor.
China's power grid is unstable and unbalanced. Therefore, the design of induction cooker should take into account the fluctuation of power grid voltage, and at the same time, it should take into account the normal use and rapid protection required by power grid fluctuation (too high, too low, high and low, lightning boosting, motor interference). Therefore, the general voltage range of high-quality induction cookers is wide: 170V~250V, which is within the allowable design voltage range.
4) Based on the consideration of function selection.
At present, domestic induction cookers have basic functions such as hot pot, boiling water, stir-frying, cooking, soup/porridge making, frying and timing. However, if we look closely at these functions, most of them are not good at cooking and making soup/porridge. Generally, these two functions cannot be realized normally, thus giving people the impression that the induction cooker can only make hot pot.
In fact, experienced researchers and designers of induction cookers will use fuzzy control technology to solve cooking, soup/porridge cooking and other functions. , so that cooking will not be scorched, sprinkled, pinched and diluted, and it will be completed automatically like a rice cooker. The soup/porridge is not overflowing, the soup is thick, and the porridge is not sticky or dry.
5) Considering the display mode.
At present, there are mainly indicator lights, digital tubes, VFD color screens, LCD and other display methods on the market. Display is just a way to give people a visual effect. When selecting the display mode, it should match the function. The function of induction cooker displayed by general indicator light is relatively simple, and the digital display is slightly practical. What is really easy to use is VFD or LCD display, because they can realize more functional collocation more centrally and intuitively, and choose a luxurious display induction cooker.
6) Considering the ceramic panel.
At present, the microcrystalline ceramic panels on the market mainly include: domestic A, B and C grade plates, Japanese NEG plates and German Schott black crystal hard plates.
Domestic board is easy to turn yellow and black, but it does not affect the use efficiency. As long as it is cleaned frequently, the surface can be kept clean, and its price is very cheap. At present, several domestic microcrystalline ceramic panel factories have passed the technical barrier in terms of high temperature and impact resistance.
Japanese NEG board is more than 5 times the price of domestic board, and it will not be yellow basically. It's really beautiful, but it's too expensive after all.
German short board is more than 3 times the price of NEG board, black, super hard, beautiful and heroic!
But based on >>
Question 6: How to choose an induction cooker? Five points to note: induction cookers are essential daily necessities in our lives. Here I will introduce you how to buy induction cookers. If the sales skills of promoters no longer confuse you, you can master some simple judgment methods in a few minutes and choose a practical induction cooker.
First of all, look at whether the panel is flat, concave and convex or inclined, and choose smooth and undamaged; Looking at the color of the panels, the black German Celan glass-ceramic panel and the Japanese NEG ceramic panel with smooth and pure white surface are both good panels, which are generally used by famous factories. Although the domestic A-grade and B-grade boards are also white, the edges of B-grade boards are rough and not as smooth as A-grade boards. C-grade boards are prone to yellowing and discoloration, and manufacturers often print patterns. Try to buy imported panels or domestic A-class panels.
Then look at the cooling fan at the bottom and choose the product with large diagonal size of the fan. It is best to use magnetic levitation, hydraulic or nano-ceramic fans. If it can be disassembled, press the fan blade by hand. If it can be pressed for about 2mm, it is magnetic levitation, otherwise it is not. Ask the shopping guide to see if you can confirm the model and brand of the cooling fan. For example, if you use an international manufacturer such as AVC, it means that the manufacturer is willing to invest the cost. Cooling efficiency will affect the service life of internal components, and a good cooling fan will reduce the noise during normal operation.
Look at the power plug again, you should choose the product of three-pin power plug. Then enter the product test. Product testing is divided into five steps:
How to choose an induction cooker? 1. Listen to the sound.
When turning on the power supply, there should be no other noise and current sound except the normal sound of the cooling fan.
How to choose an induction cooker? 2. Test key
Test whether all key functions can run normally one by one, and eliminate key faulty products.
How to choose an induction cooker? 3. Test security.
Tankless protection
Move the induction cooker down under working condition, and observe whether the induction cooker can give an alarm automatically. Generally, it will automatically cut off the power supply in about 2 minutes. For example, Mrs. Taiwan Province's induction cooker starts to alarm and stop heating within 3 seconds after the cooker leaves the induction cooker, and automatically shuts down after 90 seconds.
Empty tank protection
If the empty pot is heated for a little longer, the induction cooker will automatically give an alarm and stop heating. Some induction cookers don't have this function.
Improper heating protection
Try to put a small object like an iron spoon on the kitchen surface and turn it on. Usually, when the pot area is less than 65%, it cannot be heated normally. For example, Mrs. Zheng's induction cooker automatically alarms when heating small objects, and automatically shuts down after 90 seconds. Some induction cookers don't have this function.
How to choose an induction cooker? 4. Test the adaptability of the cooker.
In the process of electrifying and heating, the actions of taking and putting the pot are repeated many times to see whether the heating recovery time is normal. Usually, the heating will be resumed within 1-3 seconds after taking the pan back. If the recovery time exceeds 5 seconds, it means that the machine has poor adaptability to the pot.
How to choose an induction cooker? 5. Test temperature control
Check whether the induction cooker has the design of 100℃ temperature zone, and boil water with a matching pot to see if it can still maintain the boiling state at 100℃ after boiling. Improper temperature design will lead to the hidden danger of machine burning, because many internal protection functions are based on temperature monitoring. In the process of boiling water, you can move the pot to the edge of 1/4 or 1/3 and keep it for about 1-2 minutes. Should be able to continue heating, indicating that the induction cooker heating function is normal. Choose as many temperature adjustment gears as possible, and it will be more convenient to use if it can be gradually increased to 270℃ at 10 or 20.
Question 7: What do you mainly look at when buying an induction cooker?
Question 8: How to choose an induction cooker? Industry insiders remind consumers to consider the following aspects. Element 1: Power At present, the highest power of induction cookers put on the market is usually between 800~ 1800W, which is divided into several grades. The higher the power, the faster the heating speed, but it also consumes electricity, so it is expensive, so the purchase should be based on the number of people eating and the usage. Generally speaking, families with less than 2 people choose about 1000W; 2 ~ 4 candidates1300 w; 4 ~ 6 people should choose1600 w; More than 6 people can choose 1800W induction cooker to meet the requirements. Is the power constant? It is also a problem that needs to be clarified in terms of power when purchasing induction cookers. The rated power of ordinary induction cooker will differ by 30% ~ 50% when using different iron pots, while the rated power of Tianchi induction cooker is constant when using different iron pots. Element 2: The protection function checks whether the automatic detection function works normally. This function is the automatic protection function of induction cooker, which is very important for induction cooker. Pay attention to the actual measurement when buying. The method is: remove the pot when the induction cooker is working, or put something that should not be heated on the stove surface, and observe whether this function can alarm or automatically cut off the power supply according to the detection time requirements of the induction cooker manual. Element 3: Function Selection When choosing a 1 induction cooker suitable for home use, we should pay attention to the following points in function selection: 1. Is there an automatic function? 2. Is there a convenient and adjustable time control function? A well-designed induction cooker will integrate the actual use of the current family and have some humanized intelligent automation functions. Save time and electricity to help you do housework, unattended. Element 4: The use environment in the north and south is different from that in the east and west, so I remind you here that you need to choose an induction cooker with strong environmental adaptability according to your home environment when purchasing. Generally, you need to consider the following aspects: 1, power supply environment. The fluctuation of power supply voltage is different in different areas, and the deviation in some areas reaches 30%~40%. A good induction cooker should be able to adapt to various voltage states and avoid the embarrassment of buying an induction cooker and a transformer as partners. 2. Regional climate: China has a large temperature difference between north and south. Attention should be paid to the climatic adaptability of products when purchasing, such as the minimum/maximum temperature requirements for normal use and the requirements for dry and wet air in the use environment. Element 5: Simple operation Whether the operation of the induction cooker is simple or not, we need to focus on two points of the interface: 1 and the display interface. Is there a clear and intuitive work indicator light on the appearance interface of induction cooker? Is there an intuitive digital display for functions that need frequent adjustment, such as timing function, temperature control and power selection? So as to be convenient to set when in use. 2. press the button. The panel of the well-designed induction cooker will be equipped with a certain number of push-to-talk automatic functions and easy-to-use function buttons, which is convenient for you to choose quickly.
Question 9: What should I pay attention to when buying commercial induction cooker? 1. How is the induction cooker heated?
The working principle is to convert electric energy into electromagnetic energy through circuit control, and then convert electromagnetic waves absorbed by iron materials into heat energy to achieve the purpose of heating. The traditional heating method is to use open flame for heating, while the induction cooker has no open flame, which is the heating of the pot itself, reducing unnecessary energy loss in the conduction process. And compared with the traditional stove, it has the advantages of simple use, cleanliness, high efficiency, safety and intelligence.
2. Is it dangerous to use electricity for induction cookers?
No, Midea's induction cooker is an inspection-free product demonstrated by National 3C, which is absolutely safe. Although electricity is used, the safety factor is high. First of all, the range of induction cooker electricity is very wide, from 150 V to 250 V. Our plastic antibacterial and mildew-proof shell, imported ceramics and glass panels are insulators and never conduct electricity. Moreover, the induction cooker uses the principle of electromagnetic induction, not heating all materials; Third, our beautiful induction cooker has seven kinds of safety protection. Buying such a safe induction cooker is definitely your wise choice.
3.2000 watts? Does the induction cooker consume too much electricity?
People say! Now the most expensive is liquefied gas, and the least is induction cooker. The speed of induction cooker is twice that of liquefied gas, and the cost is only half that of liquefied gas. Stir-fry the dishes on the table for one minute, the meat dishes for two minutes and the soup for four minutes. One meal, four dishes and one soup only costs 12 minutes and 30 cents. A month 18 yuan, 60 cents a day-use half of liquefied gas a month. Anyway, it costs forty or fifty dollars. After one year, the money saved can buy three induction cookers. The power of induction cooker refers to the rated power, which is the maximum power. In fact, you rarely use so much power in your daily use, mainly based on the technology and materials used in energy saving. Midea's induction cooker adopts the national patent large coil and frequency conversion technology, which is efficient and energy-saving, with a thermal efficiency of 94.36% and a fast heating speed.
4. Is the blackboard better or the whiteboard better? What's the difference between imported board and domestic board?
No matter the blackboard or whiteboard, as long as it looks good. As for which panel to choose, it depends on your own personal preference. Blackboard and whiteboard are both imported and made in China, each with its own characteristics, so the so-called who is good and who is bad.
Imported plates are indeed better than domestic plates. Imported plates, whether Japanese ceramic plates or German microcrystalline glass plates, have high crystallinity, strong pressure resistance and temperature difference resistance, and never turn yellow. Because the domestic plate is a ceramic plate, the crystallinity is not as high as that of the imported plate, so it is easy to yellow after being used for a long time, but the domestic A-grade uranium panel used in our beautiful induction cooker is not like B and C of other small brands, so long as it is maintained, it can not yellow for a long time.
5, the power of the induction cooker, can the home circuit bear it?
The induction cooker does not always work at the highest power, but is controlled by a computer chip to switch between the lowest and highest power. Therefore, the household circuit can not only love, but also use many other household appliances at the same time. Moreover, Midea's induction cooker adopts soft start, that is, the default starting power is small power, which has little damage to the circuit.
6. How long is the service life of the induction cooker?
This depends on your usage time. Under normal circumstances, Midea's induction cooker is used for 2-3 hours every day, and it is no problem to use it for 5-6 years. We tell the truth and don't blow; However, if it is used for more than 10 hours every day, the service life may be shorter. But don't worry, our beautiful induction cooker has the best service for small household appliances in China in the future. The main parts are guaranteed for 3 years, and some parts are even guaranteed for 6 years. You can use them with confidence. Besides, the induction cooker is not a very expensive big piece. Now the living standard is improving year by year. You have lived for five or six years, then your living standard should be improved!
7. Does the induction cooker need a range hood?
The induction cooker is not directly heated by naked fire, and there is no gas waste gas. If the induction cooker you buy mainly eats hot pot, there is no need to use a range hood. If you cook with an induction cooker, I still suggest you use a range hood, which will make the kitchen cleaner and more hygienic.
8. I heard that the induction cooker is harmful to human body.
This is nonsense! Midea, as a responsible enterprise, can definitely tell consumers that the induction cooker has radiation, but the radiation of the induction cooker is absolutely harmless to the human body. The radiation of the induction cooker is 1/60 of that of a mobile phone, which is almost the same as that of a 40-watt fluorescent lamp and completely harmless. Besides, hospitals don't use electromagnetic physiotherapy to cure diseases and save lives, so the magnetic lines with radiation are not necessarily harmful to human body. How dare you use your mobile phone and worry about the induction cooker?
