Chapter 482 Ventilation Fan
"You're right, we just need to protect our own things, and everything else has nothing to do with us." Kang Mingyuan nodded respectfully. It's not that he is heartless. If a person doesn't know how to refuse, it's useless for them to help even if they want to. Besides, he believes that the old woman will eventually be dealt with.
After dinner, Kang Mingyuan conscientiously cleared the table and dishes, while Qiao Mo took out a pen and paper and drew a schematic diagram and structural diagram of the ventilation fan.
When Kang Mingyuan came out of the kitchen, he saw a few blueprints on the table and started to look at them. "Is this the ventilation fan you mentioned?"
"Yes, it has a square shell and a movable baffle at the back. When it is opened, the baffle will automatically open and become an exhaust channel. There is no need for a protective cover in the front. The size is about the same as the lattice on the window, so it can be embedded in the window." Qiao Mo nodded and explained the principle of the ventilation fan to him in detail.
"This is easy. I will buy a small motor tomorrow and make a fan blade and try to make it." Kang Mingyuan said that he understood. Although this thing is very simple, it can serve the public after it is made.
"In fact, the fan blades can be made of plastic, not necessarily steel." Qiao Mo reminded that she knew that the fan blades nowadays are all made of thin steel plates. After that, they are all made of plastic, which can not only reduce costs but also prevent rust and look more beautiful.
"Okay, I understand." Kang Mingyuan carefully folded the drawing and put it in his pocket.
"I'm going to sleep, please go on." Qiao Mo yawned and got up to wash up.
"I'll accompany you."
Two days later, Kang Mingyuan came back with two ventilation fans. He installed them on the kitchen window himself.
"Brother Yuan, you are fast enough." Qiao Mo stood beside him and handed him tools.
"Your drawings are very detailed, and this thing is simple. If it weren't for the time it takes to make the blades, it would be done in half a day." Kang Mingyuan said with a smile, "Wife, I thought you were only talented in languages, but you're smarter than I thought."
"Brother Yuan, you think too highly of me. I was just wondering what would happen if the fan rotated in the opposite direction. After thinking about it for a long time, I realized that the wind would be drawn outwards. If such a fan is installed in the kitchen, the air containing oil smoke in the kitchen can be drawn out, and then new air will flow in, thus achieving the purpose of ventilation." Qiao Mo could not say that this ventilation fan was made by someone else, she just plagiarized it.
"If you have thought of it even though others haven't, it means you have good thinking ability." No matter what Qiao Mo said, Kang Mingyuan felt that his wife was the smartest one.
After plugging in the power supply and securing it, he flipped on the switch and the fan started to spin. "Momo, light that newspaper and get some smoke out and see how it works."
Qiao Mo balled up the newspaper, struck a match, lit it, and threw it into the coal stove. Soon, thick smoke came out. When Kang Mingyuan turned on the ventilation fan again, the smoke floated out of the window with the air, and at a very fast speed. In less than half an hour, all the thick smoke in the room was discharged out of the window.
"The effect is good. I don't have to worry about oil smoke when cooking in the future." Kang Mingyuan nodded with satisfaction.
"There is a fan factory in Donghai, right? Will you give them this technology?" The ventilation fan is really a good thing. After installing it here, Qiao Mo wants to install it in the kitchens on Yongxing Street, the Wu family's kitchen and the old house. She doesn't want to be poisoned by oil smoke anymore.
"You designed this, so you have the final say on how to deal with it." Although this was just a small technological innovation, he would not take away her work.
