Chapter 0109 Induction Cooker, Engineer Assessment Time Confirmed!!

When it comes to the working principle of induction cookers, it’s really not very complicated.

Simply put, it is magnetic field-induced eddy current heating.

It is the use of electric current through the coil to generate a magnetic field, and when the magnetic field lines in the magnetic field pass through the bottom of the iron pan, the magnetic field lines are cut.

As a result, countless small vortices are generated, which make the iron molecules of the iron pot itself rotate at high speed and produce collision friction heat, and directly heat the food in the pot.

The composition of the induction cooker can be mainly divided into two parts, the electronic circuit part and the structural packaging part.

There is nothing to say about structural packaging, that is, upper cover, lower cover, porcelain plate, etc.

Among them, the electronic circuit part can be subdivided into: main control board, display board, electromagnetic wire reel and thermistor, fan, power line, etc.

Although the production in some places is more complicated, Lin Weidong can completely simplify it for him.

For example, various functions in later generations, steaming, hot pot, timing and so on, Lin Weidong does not need it first.

Just make a simple induction cooker that can be heated and the power can be adjusted.

After that, the light plotter can be taken out, and it is not too late for him to engage in some advanced ones.

And after Lin Weidong took out the materials from the warehouse and arrived at a workshop.

Those engineers and technicians who should not have been in the workshop also arrived here in advance, and a large group of people gathered at once.

“There’s no need to make such a fuss, I’m just making a little thing this time.”

Lin Weidong shook his head helplessly.

However, no one left, because they knew that the little things in Lin Weidong’s mouth were all incredible things for them.

Seeing this, Lin Weidong didn’t say anything more, and directly began to do it.

At the same time, he explained while doing: “What I want to do this time is a kind of kitchen utensils. ”

“The principle of operation is…”

Because the working principle of the induction cooker is relatively simple, most of the engineers and technicians present also heard Dong.

Under Lin Weidong’s explanation, he quickly grasped the direction of the circuit.

At the same time, a brand new induction cooker appeared in front of Lin Weidong.

However, Lin Weidong did not stop, but made two in a row.

“It’s done, Zhao Ming, you go to the back kitchen to get an iron pot and pick up some water by the way.”

“By the way, the kind of iron pot that needs to be flat.”

“Okay.”

Zhao Ming ran out, and after a while, he brought an iron pot.

And the guy doesn’t know where to get a couple of eggs yet.

“Hehe, I’m not afraid that I won’t be able to test it with just water.”

Seeing Lin Weidong looking at the egg in his hand, Zhao Ming said with a smile.

“Okay, put it in.”

Lin Weidong said angrily.

As the pot was put up, Lin Weidong turned on the induction cooker.

With a slight sound from the induction cooktop, the instructions have begun to start.

It didn’t take long for Lin Weidong to see one small bubble after another rising in the pot.

“The water is really hot, so fast, not at all slower than the stove!”

Looking at the gradually warming water, everyone was amazed.

Lin Weidong turned off the first induction cooker and put the pot on the second induction cooker to continue heating.

It didn’t take long for the water in the pot to tumble.

“Almost, almost, whew… Phew…”

Zhao Ming turned off the induction cooker and pulled out the eggs with a pair of chopsticks.

“Do you want one for the forester?”

“Forget it, eat it yourself.”

Lin Weidong said angrily.

“Who boils eggs in the workshop, what a big boldness.”

Director Yang’s angry voice came from outside the workshop.

Before he walked in, he smelled boiled eggs.

However, after walking in, Director Yang was also stunned.

More than twenty engineers plus technicians gathered together, which he really did not dare to provoke.

“Wei Dong, you guys are…”

“Got a little thing!”

Lin Weidong said with a smile.

“Ahem, since Wei Dong made it, it must not be simple.”

Director Yang directly skipped the topic just now, and then walked over.

“Wei Dong, give me a price.”

“Director Yang, this is an induction cooker, which is an electrical appliance that uses electric energy to cook without an open flame. You can cook without an open flame and use electricity. ”

Director Yang was also surprised by this.

It seems that the egg just now was boiled with this induction cooker.

“That kind of thing doesn’t require much electricity.”

“Of course it’s not big, and the electricity in the factory will be provided by solar panels after that, will you care about this amount of electricity?”

When Director Yang heard this, he also laughed: “If this is the case, it will be too convenient.” No coal, no gas, as long as there is electricity, you can cook. ”

“With this thing, our old-fashioned cooktops can be eliminated.”

“That’s not going to work.”

Lin Weidong quickly shook his head.

“Director Yang, this induction cooker is good for making some simple meals.”

“But to talk about small stir-frying or something, there are still some gaps between dishes made with induction cookers and dishes cooked over open flames.”

“This way.”

Director Yang nodded, and was not too disappointed.

“That’s enough, it’s a big deal to leave some stoves when you replace them.”

“At least it makes it easier for the workers in the back kitchen, and now it’s getting hotter.”

“But these things still have to be delayed, and I came this time to tell you a big thing.”

“The notice has come down, and this worker-level assessment is on this Thursday.”

“The exams for engineers and technicians are on Fridays.”

“This Friday!”

Lin Weidong also had some expectations, although he was now very skilled, he was still only a seventh-level engineer.

The engineers who came last time were all of a higher rank than him.

This level of his, it should also be mentioned.

Even if it is low-key, it can be upgraded by two or three levels.

“That’s right!”

Director Yang nodded and continued, “So don’t be busy with other things these days, concentrate on preparing for the assessment.” ”

“I hope that our rolling mill can have a few more engineers, who are already engineers, and the grade will also be raised.”

“Director Yang rest assured, as long as they play without mistakes, they can pass a few no matter how they say.”

“In the past few days, I will teach them some more problems that may be encountered in the assessment process.”

“That’s up to you.”

Director Yang patted Lin Weidong’s shoulder and left the workshop.

“Okay, let’s put the machine transformation away first, and give you a few professional lessons,” Lin Weidong said with a smile.

“Thank you forester!”

Many engineers and technicians quickly thanked them.

At this time, someone suddenly ran over and shouted: “Forester, there is your phone!” ”

“Phone?”

Lin Weidong was a little puzzled, who would come to him.

“Did you say who it was?”

“He said it was a forester, your teacher…”

Before the man finished speaking, Lin Badong hurriedly walked out to…
