What is the reason for the slow heating of induction cooker?

That's right, it's not easy to use, I took it to the supermarket and tried it, and it boiled quickly, and then I took it back and tried it at home, and it didn't work, and the situation was the same as above, and then I took it to another room and tried it

Yes, in many induction cookers, there will be e7, but it is a sensor failure, if you will repair and check the virtual welding of the sensor and weld it firmly. Follow-up:

I'm an electrician.,I think it makes sense when you say that.,Oops, "The money is also spent.,The key to buy back is not a few days.,This kind of failure occurs.,Sometimes there is.,Sometimes there's not.,Sometimes it's not heated when it's stir-frying.,The display is still normal," If I open it, the label will definitely tear, if it's not a problem there, and then get the after-sales maintenance point The other party will repair it for me? ：

Oh, peers; I have been an electrician for 16 years, and I also repair and make various electrical appliances; In my experience, there is only replacement, you will not repair only replacement, if you open the manufacturer, it doesn't matter, and then get the after-sales maintenance point The other party will definitely not give maintenance. You are ** bought, you can find a peer to manage it to exchange. Follow-up:

I want to ask about the prawns, is it a 7-day return, a 15-day replacement, and a 1-year warranty? ：

I don't understand the after-sales problem, but the warranty for all electrical appliances is at least one year.

As for your induction cooker, try it again, but I think that the induction cooker may fail significantly if it is used in a low-temperature environment for a period of time, and the failure rate is very low if it is operated in a high-temperature environment, even if it is a virtual weld, the failure rate is higher at low temperature.

This one is more professional, involving several resistors and capacitors, it is best to find a repair engineer and let them see, if the parameters are not enough or damaged, of course it will affect the heating.

It's your pot's problem, right? The more the bottom of the pot is in contact with the induction cooker, the faster it heats up, and the bottom of the pot is best flat.

1. The unstable voltage of the outside world causes the internal protection circuit of the induction cooker to protect itself.

2. The induction cooker has been used for too long and the temperature is too high, resulting in the automatic protection of the protector.

3. If there are no ingredients added to the pot, the empty pot will be boiled, and the induction cooker will automatically power off for protection.

4. Generally, the reason why the induction cooker does not heat is because the temperature is too high and the sensor alarms and automatically loses power. Clean the heat vents and fan of your cooker, and then wait a while for it to return to normal.

The reasons for slow heating of induction cooker are as follows:

The resonant capacitance capacity becomes smaller, resulting in the peak pulse voltage generated by the power tube during the cut-off period being greater than the set value, which makes the power tube overvoltage protection circuit operate frequently, causing the power tube on-time to become shorter and the cut-off time to become longer.

The voltage of 300V is less than the normal value, and the magnetic field strength generated on the processing plate becomes smaller when the power tube is turned on.

The overvoltage protection circuit element of the power tube is changed, so that the overvoltage protection action is advanced.

The damage of the oscillation circuit element makes the discharge time of the oscillating capacitor longer, resulting in the amplitude of the driving excitation square wave added to the driving circuit becoming smaller, and the on-time of the power tube becoming shorter.

When an abnormality occurs in the current detection circuit element, the detection and sampling voltage added to the CPU becomes smaller, and the CPU detects that this voltage is less than the normal value, mistakenly thinking that the setting power is small, and the square wave pulse duty cycle is narrowed.

The PWM pulse modulation circuit element is abnormal, so that the control voltage added to the CPU output to the pulse width adjustment circuit is small.

The 18V output voltage is abnormal, which makes the power tube excitation insufficient, resulting in the decrease of the output power of the induction cooker. In this case, it is easy to cause excessive loss of the power tube and burn out.

The induction cooker heats slowly because of the low heating power. Please check whether the mode switch is turned on by mistake on the low-power working mode. If the mode switch is on the high power (full power) mode, but still the heating is slow. Please send it for repair.

Today, a customer took an induction cooker and said that the heating was very slow, and the water could not be boiled for half an hour. Disassemble and detect, the vulnerable parts and hardware are basically good. According to the maintenance experience, it is estimated that it is a virtual welding, and after the Kangtong wire is welded, troubleshooting.

Generally, the induction cooker E7 is an open circuit with a 1GBT sensor. or caused by virtual welding, the same fault as yours, it is recommended that you replace.

The reason for the slow heating of the induction cooker, the slow heating of the induction cooker is maintained.

It should be aging, or it is a problem with parts, you can go to the after-sales service to take a look.

The slow heating of the induction cooker indicates that most of the circuits of the induction cooker are basically working normally, but the high level time added to the control pole of the power tube becomes shorter, which makes the on-time of the power tube shorter, resulting in a small high-frequency magnetic field generated by the LC oscillation circuit.

Or the LC oscillation circuit components are damaged, resulting in the magnetic field formed by the ** plate becoming smaller, so that the output power of the induction cooker decreases. If the induction cooker is slow to heat, you can contact the after-sales personnel of the induction cooker and send the induction cooker to a nearby after-sales maintenance center for inspection and maintenance.

There is an adjustable resistor that adjusts the power inside, to see if the contact is bad, if you turn up the overload...

Why think it's heating up slowly?

All induction cookers, the factory has been tested for performance, and its power is adjusted according to the design capacity of the product.

Since it can be heated, it is normal. Unless the grid voltage of the place of use is much lower than 220V.

According to the situation you described. In fact, there is an induction cooker. He wasn't too high-end at first. After encountering this situation. You have to adjust the upscale in time. Isn't he hot as fast as he is?

It's very good to repair, first disassemble it, then find the IGBT to see the model written above, and directly buy another one of the same model, the soldering iron is broken, and the new one is soldered, provided that the heating you said is slow, not that it will not work.

Non-professionals, it is better not to repair, the gains outweigh the losses, safety first.

Poor adjustable resistance (VR1) or capacitance (; Bad, replace it and try it.

The induction cooker heats up slowly, and the maintenance method is very simple.

5uf capacitor Try replacing the capacitor.

There is a three-pin adjustable resistor on the side of the open bottom shell circuit board, which can be adjusted on a trial basis, which is specifically responsible for the power size.

What is the reason for the slow heating of induction cooker?

1. The voltage of the external environment of the induction cooker is not good, so the internal heating speed will be reduced in order to protect itself.

2. Use the induction cooker for a long time. The temperature was too high, and in order to prevent accidents, I slowed down the heating by myself.

3. The inside of the pot is empty, to prevent the empty pot from heating, the induction cooker will slow down the heating speed for self-protection.

4. Usually the slow heating of the induction cooker may cause the sensor to issue a warning due to high temperature, and then automatically power off. Clean the heat dissipation holes and fans of the induction cooker frequently, and wait for a period of time to open and use it to recover.

Precautions for using an induction cooker:

1. It is recommended to use a dry rag immediately after the induction cooker is used up, and wipe all the surface dry, because there will be some leftover substances in the process of use, such as leaves or water, etc., clean the induction cooker frequently, and then place it, and use it every time it is the same as new.

2. Generally, when using an induction cooker, you should choose steaming or hot pot according to your own needs. It will be implemented in accordance with the regulations, and you can't just say that you want to hurry, even if you cook a noodle, turn on the fire to the maximum, which is easy to shorten the service life of the induction cooker. And after use, you must remember to turn on the fan and then cut off the power supply.

As we all know, induction cooktops are indispensable kitchen appliances in daily life. So the question is, do you know what causes the slow heating of the induction cooker? What should be paid attention to in the daily use of induction cooker? Let me reveal the answers for you one by one.

What is the reason for the slow heating of induction cooker?

The main reasons why the induction cooker heats up slowly are as follows: first, the external voltage exceeds or is lower than the voltage of the induction cooker; Secondly, the internal temperature of the induction cooker is too high; Finally, if no ingredients are added to the pot, the induction cooker will be forced to cut off the power. Of course, there may also be external causes, such as:

Temperature sensor open circuit, tube overpressure protection, etc.

Precautions for daily use of induction cooker.

1. Install special power cords and power sockets.

Due to the high wattage of induction cookers, power cords and sockets should be installed according to the needs of use. Normally, it is mainly a copper core wire with a current of 15A, and of course, the sockets and switches used in complete sets must also meet the corresponding requirements. Otherwise, in the process of working the induction cooker, it will cause short circuits in wires and sockets.

In addition, if you can afford it, it is recommended to install a safe box at the outlet to ensure the safety of yourself and your family.

2. The induction cooker should be placed steadily.

If the induction cooker is not balanced, it is easy to spill the food in the pan during the stir-frying process. Therefore, the induction cooker must be placed smoothly, otherwise there is a danger that the pot will slip out.

3. Ensure that the air inlet and outlet holes are unobstructed.

During the use of the induction cooker, it will increase with the temperature in the pot, so the induction cooker must be placed in a place with air circulation, and the air outlet should be more than 250px away from the wall and other items, to ensure that there are no objects obstructing the air hole of the furnace body.

4. Choose the right pots and pans.

I believe we all know that the load-bearing of the induction cooker is limited, usually the load-bearing of the induction cooker is more than 5 kg, and the bottom of the pot can not be too small.

Summary: After reading the above introduction, I believe you have a further understanding of what is the reason for the slow heating of induction cooker. If you need to know more about it, please continue to ******, and more exciting content will be presented to you in the future.

The reasons for the slow heating of the induction cooker are as follows:

1. Voltage factor. Under normal circumstances, the working voltage of the induction cooker is set to 180V-250V, if the voltage is lower than 180V, the induction cooker will display the corresponding fault**, and the voltage is higher than 250V, the overvoltage protection will also be displayed, and there is also the corresponding fault ** display, the voltage is between 220-240V, the working efficiency of the induction cooker is the highest, and the voltage is between 180-200V, and the work is slower.

2. Tableware reasons. After being used for a long time, especially the layering of the bottom pot, the uneven bottom of the pot, and the thick layer of the bottom of the pot, it will lead to too slow heating.

3. The power tube of the induction cooker is aging. This situation is more complicated to repair, and the maintenance of induction cooker component failure is recommended to be handed over to professionals, especially partners who are not familiar with the circuit should not disassemble the machine for maintenance without authorization, so as to avoid causing more serious damage.

Precautions for using an induction cooker:

1. The power cord should meet the requirements. Due to the high power of the induction cooker, when configuring the power cord, the copper core wire that can withstand the current of 15A should be selected, and the sockets, plugs, switches, etc. used should also meet this requirement. Otherwise, the high current when the induction cooker is working will cause the wires, sockets, etc. to heat up or burn.

Also, if possible, it's a good idea to install a fuse box at the power cord outlet to ensure safety.

2. Place it flat. The table top where the induction cooker is placed should be flat, especially when eating hot pot on the dining table. If the table top is uneven, so that one foot of the induction cooker hangs in the air, the gravity of the pot will force the stove body to deform or even damage when used.

In addition, if the table top is tilted, when the induction cooker heats the pot, the micro-vibration generated by the pots and pans is also easy to cause the pots to slide out and cause danger.

3. Ensure that the pores are unobstructed. The induction cooker in work heats up as the pot heats up. Therefore.

When placing an induction cooker in the kitchen, ensure that there is no object blocking the inlet and exhaust holes of the stove. Do not pad (stack) objects or liquids that may damage the induction cooker on the sides and under the furnace body.
