Brief introduction of Dinglong high-power commercial induction cooker

First, the product working principle

As a new cooker in the kitchenware market, high-power commercial induction cooker (cooker) breaks the traditional open fire cooking method and adopts the most advanced magnetic field induction eddy current heating principle. That is, when the current passes through the coil to generate a high-frequency alternating magnetic field, the magnetic lines in the magnetic field pass through the bottom of the iron pot, and countless tiny eddy currents are induced, so that the pot itself is heated at high speed, and then the food in the pot is heated.

Second, the main performance and indicators

1, high-power induction cooker (stove) adopts the principle of magnetic field induction heating.

High-frequency (20-40KHz) current generates an alternating magnetic field through an annular coil. When the magnetic lines in the magnetic field pass through the bottom of the iron-containing magnetic pot, countless tiny eddy currents will be induced, which will make the pot itself heat up at high speed and then heat the food in the pot.

2, the use of high-power induction cooker (furnace) pot material requirements

Because nonmagnetic materials can't effectively accumulate magnetic lines of force and hardly form eddy currents, they basically don't generate heat energy. In addition, magnetic materials with particularly poor conductivity generate little eddy current and little heat (P+U2/R) due to their high resistivity. Therefore, the materials used in induction cookers (stoves) are iron materials with relatively good conductivity, as well as alloys and composite materials. The pots commonly used in induction cookers (stoves) are pig iron, A3 iron and stainless steel iron pans.

3. Safety analysis

Because the coil disk of the high-power induction cooker (stove) is not in direct contact with the pot body, the pot is heated by electromagnetic induction, so there is no danger of electric leakage.

Because the coil disk of the high-power induction cooker (stove) itself has a magnetic stripe array, the pot body can concentrate on absorbing the magnetic field lines, and it is shielded by the metal shell, so the leaked radiation is very low and will not cause harm to the human body.

Third, the main features of the product

1, the power adjustment range of high-power induction cooker (stove) is wide, and it can be continuously adjusted within the rated power range of 0.2KW-50KW.

2. High-power induction cooker (stove) has a wide range of power supply voltage adaptation, unique over-voltage and under-voltage regulation characteristics, and can be used for a long time in various power supply environments.

3. The safety protection function of high-power induction cooker (stove) is perfect, which can protect the power supply voltage from being too high, too low or sudden change, and the conventional over-temperature protection is faster and more accurate.

4. Starting the self-diagnosis function and the two-hour non-working timing shutdown function can detect whether the working environment of the induction cooker (stove) is normal (whether the voltage and ambient temperature are appropriate or whether there is a fault inside the body). If no one operates the relevant knob of the induction cooker (stove) for a long time, the machine will think that the operator has forgotten or gone out, and will automatically shut down after two hours, making it safer to use.

Four, the main characteristics of the product (compared with the traditional stove)

1, more energy saving (high thermal efficiency)

The advantage of induction cooker is its high thermal efficiency. As a high-tech product advocating "green kitchen culture", the heating principle of traditional stoves such as electric stove, liquefied gas stove, gas stove, rice cooker, etc. is to burn the bottom of red ware first, and directly heat the food in the pot. The burning air consumes some heat, and the thermal efficiency is 40%-60%, which is characterized by high heat consumption and slow cooking. The thermal efficiency of induction cooker (stove) can reach 95%.

2. It's safer (there are many advantages to cooking without open flame)

The use effect of induction cooker (stove) is completely different from that of gas stove. There will be no open flame during use, and the induction cooker (stove) itself will not generate heat. It will never cause fire incidents like other stoves, and there will be no incidents caused by gas leakage.

3, more environmentally friendly (healthy, clean)

Farewell to the fireworks-filled kitchen war is a great wish of modern chefs. When the induction cooker (stove) is heated, it does not release any substance, has no fire and smoke, and does not raise the room temperature; However, when the traditional coal, liquefied petroleum gas and gas are burned, the room temperature is rising and the kitchen fume is increasing due to the combustion of air. At the same time, it will release harmful gases such as carbon monoxide, carbon dioxide and sulfur dioxide, which will affect human health. The use of environmentally-friendly induction cooker (cooker) does not have many pollution problems of traditional cookers, and really realizes cleaning rooms and protecting the environment. You can work without fire, especially in summer, so it is clean and comfortable.

4, more accurate (precise temperature control)

The induction cooker can flexibly and accurately control heating power and cooking temperature according to different cooking needs of users. The input power of induction cooker (stove) is usually between 0.2 kW and 50 kW, and the temperature (constant temperature system) required for cooking can be selected at will and set at a certain level. The reason why a chef can cook delicious dishes is that he can master the heat. The induction cooker (stove) adopts advanced scientific methods to develop a series of constant temperature devices from normal temperature to 350 degrees. When cooking, you can choose the required temperature, which is very convenient and can make the cooked food achieve the ideal color and fragrance.

5. More functions (frying, frying, frying, boiling, stewing, etc. )

Induction cooker (cooker) is undoubtedly the all-around champion of frying, frying, frying, boiling and stewing. Compared with the single function of microwave oven, it is undoubtedly a great progress, and it saves kitchen space to the maximum extent, and it is easy to install and move, and there is no danger of radiation leakage.

6, more convenient (simple operation, beautiful appearance)

Convenient operation: At present, some common cookers (such as microwave ovens) have several operation buttons, while induction cookers (stoves) only need relatively few buttons to complete the operation. Desktop frying furnace: small, flexible, hygienic and easy to move; The floor-standing induction cooker (stove) can work only by connecting the power supply; It can adapt to all kinds of places, especially fire-forbidden places and empty and windy places (such as basements, gas stations, liquefied gas centers, wineries, workshops, warehouses, etc.). ) Because its working process does not produce open flame, and there is no high temperature and no waste gas.

Performance comparison between commercial induction cooker and diesel stoves: Data/Project commercial induction cooker φ900-pot diesel stoves φ900 number of boilers 1 set 1 set rated energy consumption of 25kW/h- average energy consumption of 20 kWh, unit price of 7L fuel of 0.8 yuan /kWh 6.5 yuan/hour fee 16 yuan 45.5 yuan, and daily service time of 4 hours and 4 hours. The daily fee in 64 yuan is 65438+. The price keeps rising. The energy saving is excellent and the environmental protection is excellent and the safety hazard is poor. There are few leaks, explosions and fire hazards. The thermal efficiency is 95% 25%, the noise is about 45 decibels, the oxygen content in the working environment is about 80 decibels, 20.8% 16.60%, the exhaust gas does not emit carbon dioxide, carbon monoxide and sulfur dioxide, the temperature rise is fast, the maintenance rate is low, and the general service life is/kloc-0

1, each φ900 single-head commercial induction cooker saves 3540 yuan compared with diesel furnace, saving 42480 yuan a year.

2. It can save the investment cost of flue and smoke pipe and reduce the kitchen space occupied by flue.

3. Reduce the risk of fire caused by air leakage in the use of liquefied gas.

4, the induction cooker is easy to use, reducing unnecessary empty burning, and can be turned on and off.

Common faults and maintenance methods of Dinglong commercial induction cooker

When the induction cooker works abnormally or fails to work, there are the following common faults and troubleshooting methods: common troubleshooting methods 1, no "b" sound when powered on ① Whether the connector at the main power cord of the induction cooker is firmly connected; Check whether the leakage switch or air switch trips; Check whether there is electricity leakage, and then open the gate after troubleshooting. 2. There is a "B" sound when power is on, but the twist switch cannot be heated; ① Before power on, the switch is not placed in the off (standby) position; Turn the machine knob to the OFF position, and then turn it on again. ② The switch is twisted and twisted, and the knob with the same number on the display screen is damaged. Replace the knob. 3. There is no response during the operation of the induction cooker. Or feel that the power suddenly decreases and then returns to normal to repeat the above fault; ① If you don't operate the knob for 2 hours in a row, the machine will automatically shut down, because the operator thinks he has gone out or forgotten to operate, so he can restart it.

(2) the machine electrical overheating protection, check whether the ventilation is good, whether the cooling fan is normal. 4. During the heating process of induction cooker, the display is as follows

Display the letter "2"; This is because the temperature in the pot is too high. Please put a substance into the pot before heating. General maintenance points of commercial induction cooker

1, basic code:

E 1: no boiler alarm E2: boiler overtemperature protection E3: boiler thermistor open circuit; E4: IGBT thermistor short circuit E5: IGBT thermistor open circuit E6: voltage too low E7: potentiometer thermistor short circuit E8: IGBT thermistor short circuit E9: voltage too high.

Note: After power-on, the red light (power light) flashes, the blue light does not, and the display screen shows "-". At this point, the switch is turned on. If the knob switch is turned and the display element changes, it means that the knob switch is damaged or the related plug or connecting rod is loose. Replace the switch potentiometer (encoder) at this time. If it cannot be discharged, it may be that the switch circuit is abnormal.

E 1: no pot. E 1 will be displayed after startup (after a few seconds, the extension will display 1 or "-"), and the red light will flash and "one" will be displayed at the same time.

A, cooking stove/flat-head low-soup stove may not put the pot, and see if it is normal after putting the pot.

B. If the cauldron and other pots display 1, check whether the distance between coils has changed or whether the pots are magnetized. Please use the special pot issued by the company at this time.

C, red light, showing the currently set gear, blue light flashing, repeated, the pot is wrong or the coil is far away.

E2: pot (coil) over-temperature protection. After a period of startup, E2 appears. Check whether the coil fan is running. If it is running, it is likely that the thermistor of the coil is aging. At this time, replace the coil without temperature seat.

E3: Turn on the thermistor and replace the temperature measuring base of the coil.

E4: E4: The IGBT thermistor is overheated, and the cooling fan on the movement does not turn, or it is too slow. Check the fan and plug. If there is no problem, the relay may be damaged. At this time, the emergency repair method is: clamp the upper shell of the relay, even if the contacts of the relay are always open. But make it clear to the customer that the power supply will turn, but it will not affect the use.

E5: IGBT thermistor is open. At this time, try to change the movement or professional maintenance to remove the board and replace the aluminum temperature measuring base.

E6: The voltage is too low, and the power supply voltage is not enough.

E7: The pot thermistor is short-circuited, and the temperature measuring base at the bottom of the pot is faulty. Replace it and solve it.

E8: IGBT thermistor is short-circuited. At this time, try to change the movement or professional maintenance to remove the board and replace the aluminum temperature measuring base.

E9: The voltage is too high and the power supply voltage is too high.

2. There is no response when power is turned on, and the display is not bright. Turn the switch handle to start working. At this time, disassemble the front panel of the furnace and check whether the cable of the monitor is broken or the plug is loose.

3. There is no response when power is turned on, the display is not bright, and the switch handle cannot be turned on. At this time, when the power is cut off, the front plate of the furnace will be disassembled to check whether the cable of the transformer is damaged or the plug is loose. If the fault still exists, it may be that the transformer is damaged. Note: This operation must be carried out in case of power failure.

4. When the power-on display is normal, twist the switch handle, and there is no response. At this time, it is necessary to check the potentiometer or encoder of the switch handle to see whether the potentiometer and encoder rotate together when the handle is turned, whether the wiring is intact and whether the plug is loose. If all these are intact, open the cover of the chassis, check whether the plug of the switch wiring is loose and plug it in again. If it cannot be discharged, replace the switch. Note: If it is a potentiometer, the switch will beep all the time when it is blocked.

5. The machine works normally, but after working for a period of time, the front switch of the machine trips automatically, and it can work again after being turned on. This situation is generally due to the insufficient overcurrent capacity of the front switch, which requires the customer to replace the switch.

6. You can't turn it on, and it will trip every time you turn it on. At this time, disconnect the machine grounding wire and hang it up, and then turn it on. If it can be turned on, it means that the machine has leakage. Check the insulation cotton, fan or switch of the coil. At this time, you have to remove the suspected parts one by one. When you remove which one can close the brake, it means which part is broken and must be replaced or repaired. Note: After repair, the ground wire must be put back.

7. If the fans don't turn, first check whether each fan doesn't turn. If one fan rotates, the fan control circuit is good. At this time, check the connectors or plugs of the non-rotating fans. If all the fans don't turn, it may be that the control circuit is damaged, and the above E4 method is used for emergency repair.

8. After electrifying, the digital display is chaotic, the pen is missing, the buzzer is silent, and the display is different every time it is electrified. The main chip or crystal oscillator or two filter capacitors beside the crystal oscillator are damaged.

9, power-on trip, first of all, to determine whether the trip is caused by machine damage or the poor quality of the customer's switch itself.

Commercial induction cooker's Interpretation of Magnetic Radiation

Today, with the progress of society, the creation of life by science and technology is becoming more and more obvious, the living standard is getting higher and higher, and the quality of life and physical health have become more and more concerned topics.

With the induction cooker directly entering the lives of ordinary people, people seem to be more concerned about the extent to which the magnetic leakage of induction cookers will affect their health. At present, the relevant state units are also looking for cases in this regard. It is gratifying that so far, there has not been a case of magnetic leakage produced by induction cookers (the working frequency range of induction cookers is 20 kHz ~ 40 kHz) that is harmful to human health. Of course, people see that mobile phones do harm to their slaves, but we must see that the working frequency of mobile phones is 900MHz/ 1800MHz. Compared with the high frequency of induction cooker, the propagation distance is 45000 times that of induction cooker. We tested the induction cooker ourselves, and the electromagnetic wave was almost zero at a distance of 50cm from the working area of the induction cooker. For example, when the current frequency emitted by the radio is 20KHz~40KHz, and the radio is placed 50cm away, the radio can't receive the signal sent by the radio at all. Therefore, experts only advise people to stay away from 50 cm when working in induction cookers.

Back to our present commercial induction cooker, because the power of commercial induction cooker is 10 times higher than that of induction cooker, it makes sense to say that the magnetic leakage is higher than that of induction cooker, but it must be explained that the frequency of induction cooker and commercial induction cooker is the same. It can only be said that in the same working range, the electromagnetic wave in commercial induction cooker is stronger than that in the induction cooker, but it is very small outside 50cm. Another advantage over induction cookers is that commercial induction cooker adopts stainless steel shell. As we all know, metals have a shielding effect on magnetic fields. We have also measured it with the ML428B magnetic radiation tester of Anruitu Company in Japan. At the same distance, the radiation generated by the induction cooker is 60, while the commercial induction cooker with a gold shell is only 7, so the electromagnetic radiation in commercial induction cooker is not much less than that of the induction cooker.

Assembly process requirements of induction cooker

1. Installation of coil:

1. When installing the coil, it is necessary to determine the installed power and the size of the pot, and then select the coil with corresponding inductance and size.

2. There is no sundries on the surface and bottom of the coil, and the enameled wire is not damaged or broken. The positioning column is free from looseness and falling off.

Seven. Inspection and aging

Connect the completely installed induction cooker to the power supply in the designated area, and age at the high temperature of 40 degrees at room temperature 1h, which requires unprotected and abnormal conditions. Aging at room temperature for 2 hours, check that the temperature in the machine shall not be higher than the standard. Hand over the machine to the packaging department for cleaning after aging.

Calculation method of commercial induction cooker product power and time

Power calculation formula

Power (KW)=330X water quantity (liters or kilograms) ÷60÷ Time required (minutes)

For example, if it is required to boil 65 kilograms of water in 30 minutes, the power needs:

330X65 kg ÷60÷30 min = 12KW

Calculation of boiling water velocity

Time (minutes) =330X water quantity (liters or kilograms) ÷60÷ power (kilowatts)

For example, it is required to calculate how long it takes 12KW to boil 65KG of water.

330X65KG÷/kg12kw = 29.8 minutes.

1 how much heat is needed for the temperature rise of the water 1 degree?

Heat Q= specific heat capacity of water C× mass of water m× temperature difference t Q=CxMxT.

Volume 1 l = 1 cubic decimeter = 1x 10-3 cubic meters.

Mass of water m= density of water p× volume of water v =1.0×103×10-3 =1kg m = pXV.

The temperature difference is 1 (degree) t= 1 m= 1kg. The specific heat capacity of water c = 4.2×10.3 j/kg.

So the heat q = c× m× t = 4200×/kloc-0 /×1= 4.2×103 = 1 000 calories =1calories.

Power consumption?

1kw/h generates 860 calories.

So the power consumption is1/860 = 0.00116 degrees.

For example:

It takes 5200 calories to raise 65 kilograms of water from 20 degrees to 100 degrees (80 degrees).

1 l diesel generates 8330 calories (set thermal efficiency 100%, diesel density 0.85kg/ l). The thermal efficiency of diesel stove is 35%, and it needs oil consumption 1.7 liter, and diesel 5.8 yuan/liter, and the cost is about 10 yuan.

Using an induction cooker, the thermal efficiency is 95%, and it needs to consume 6.3 kWh, which costs 6.3 yuan.

The cheaper the electricity bill, the more economical it is, especially in Yunnan, Guizhou and other places where electricity is encouraged!

So electricity is 40% less than diesel!

Commercial induction cooker route selection requirements

I believe that many customers or our novice business partners who sell commercial induction cooker will encounter the problem of how to use wires in the renovation of kitchen equipment. How many square meters of wires will be used to install this batch of high-power commercial induction cooker? Below we will provide general wiring specifications. For your reference: power 8kw12kw 25kw 30kw 90kw150kw current12a18a37.5a45a135a 225a Line specification 4mm210mm2/ Kloc-0/0mm210mm216mm2 50mm2 70mm2 calculation formula:

Current calculation formula: current = power (watt) ÷(380× 1.732)

Simple calculation formula: current = power (kW) × 1.5

The calculation formula of wire diameter specification is: current ÷5.

Theoretically, each square wire can pass a current of 5A, which can be divided into four or five points according to the actual situation.
