The first lady is sweet and sweet

Chapter 303 Technical work (three more)
Shen Zhouheng looked at Qi Yaoyao in surprise and said, "Do you need it?"

"Yes, it is convenient to connect the stove to use hot water." Qi Yaoyao stared at him and nodded hurriedly, "You want to go out and get hot water in the winter!" She shuddered and said, "Pick up the food from the kitchen. Come on, isn't it cold?"

"I'll discuss with Qin Laowu, and put a soil stove here in the hall." Shen Zhou walked out of the bedroom and looked at the hall and thought, "This stove is only used in winter, and it can be moved out when the weather is warm."

"Of course, it will be hot in summer." Qi Yaoyao said with a smile.

"I don't know how Qin Laowu's stove is?" Shen Zhouheng said to himself.

"It should be possible! They didn't cook all the cooktops themselves." Qi Yaoyao looked at him with dark eyes and said.

"It would be a little troublesome to connect the kang and the stove alone," Shen Zhou said earnestly looking at her with amber eyes.

"Is it difficult?" Qi Yaoyao looked at him in surprise and said, pointing at the wall, "As long as it doesn't get through, it's fine."

"It's not that simple." Shen Zhouheng's deep eyes focused on her and said, "At the connection between the kang and the stove, we call it the 'throat eye', which is a hyperbolic shape." Release her, Fingers gesturing.

"Understood." Qi Yaoyao nodded with a smile, what he said was like the cooling tower of a later thermal power plant, with a hyperbolic shape.

Don't underestimate this heated kang, the ancestors have such profound knowledge.

Shen Zhou stared at her and explained seriously, "The connection between the fire kang and the earth stove is based on experience, and the "throat eye" is small. When there is no wind, the pulling force is small, and the smoke cannot be discharged; "It's too big to stay. When it's windy, the inside of the kang is so powerful that all the fireworks are drawn into the kang. The pot can't be turned on for the time being, and the rice can't be cooked."

This room is almost seen, go outside.

"Where are you going to tell Yaoyao!" Shen Zhouheng hurriedly came over to support her and said.

"Let me see this outer wall?" Qi Yaoyao stood at the door and looked at the thickness of the blue brick wall.

"What are you looking at this for?" Shen Zhouheng followed her line of sight.

"The wall is thick enough, well insulated, warm in winter and cool in summer." Qi Yaoyao stood at the threshold and gestured with both hands.

"Haha..." Shen Zhouheng heard the words and said with a chuckle, "You are really worried."

"What are you laughing at?" Qi Yaoyao rolled his eyes at him angrily and said, "This is a very serious question."

"Yes yes yes!" Shen Zhou nodded with a smile, "Then you should go and see the internal structure of the heated kang."

Shen Zhou supported her and walked into the bedroom again, pointing to the half-laminated heated kang and said, "If the cold wall in this kang is thin, the heat preservation is not good, and the cold wall will be frosted and iced in winter, and the heat loss will be large. Likewise If the cold wall is not plastered tightly, the air leaks, and the kang won't get too hot no matter how it is burned."

"Where's the kang noodles?" Qi Yaoyao pointed at the bluestone slab and said, "It won't be like this!"

"How is that possible?" Shen Zhouheng looked at her amusingly and said, "It will be smoothed with mud, and it will be very smooth." The index finger pointed at the kang, "But when the smoke touches the bottom of the kang board, the resistance to flow is the It affects the speed of smoke separation and exhaust, and directly affects whether the kang surface is hot enough.”

"Mmmm!" Qi Yaoyao nodded lightly.

"The fire bricks and windward bricks in this kang are carefully placed. Improper placement will cause a large resistance to smoke exhaust in the kang, resulting in poor smoke exhaust, which will cause uneven heating at the head and tail of the kang." Shen Zhou Heng pointed at the head and tail of the kang and said.

"In this kang hole, the flue and ash pits are too deep, and the air-conditioning will accumulate in the kang. When the stove is on fire, the air-conditioning and hot smoke in the kang will exchange, resulting in eddy currents, and the kang stove will not burn well. "Shen Zhouheng explained seriously.

"You... can you still do this?" Qi Yaoyao looked at him in surprise and said, "Did you learn it specially?"

"You can tell by looking at the fire when cooking." Shen Zhouheng tilted his head slightly and looked at her and said, "The stove is full of firewood, and there is no space, so it must not be lit."

Qi Yaoyao smiled and suddenly said, "Have you ever thought about why? Isn't it that everyone gathers firewood with high flames!"

"I really thought about it, maybe it's too crowded in a confined space!" Shen Zhouheng thought about it seriously and looked at her and said, "Let's go deeper..." He scratched his head and said, "I don't seem to know. "

Qi Yaoyao smiled when she heard the words, why are there so many?Not many people are looking into it.

"This kang can't be just smoothed out! Although the appearance doesn't need to be carved or anything? But it also needs to be decorated a little! Especially the edge of the kang."

"Yes! This kang is edged with wood, using a whole piece of wood." Shen Zhou pointed to the edge of the kang and said, "The wood must be straight, no scars, no stubble, and the width and height must be moderate. A good kang is made of jujube wood, and if there is no jujube wood, ash will also work. Ordinary people will use poplar or pine wood."

She looked at her with bright and translucent eyes and said, "If Yaoyao wants a pot stove, cook on a fire in winter, and the rice will be cooked on the kang. In summer, use adobe to block the eyes of the kang to prevent fire from entering. A kang without a stove is a stove with a kang. , it can heat the kang, and it is convenient to use hot water.”

Fortunately, the kang is only half-coated, and the outer wall of the house next to the hall is not well-coated, and the overall modification is much easier.

The uncles and nephews of the Qin family are all honest people, and they work very hard. They set up four kangs and an earthen stove, and it took half a month to complete.

Earn some pocket money to supplement the family before the autumn harvest, and go home just in time for the autumn harvest.

"Does this kang still need to be dried?" Qi Yaoyao said, looking at the coiled kang in the bedroom.

"Of course it's still wet." Shen Zhouheng slightly tilted his head and looked at her when he heard the words.

"This baking will take at least ten days and a half month!" Qi Yaoyao's smart eyes looked at the heated kang and said, "Just in time for winter."

"Hmm!" Shen Zhouheng nodded with a smile when he heard the words, and supported her, "Let's go! The smell in this room is not very good."

The two sat on the bamboo chairs in the corridor, "I didn't expect to get married in the end." Shen Zhouheng muttered to himself.

"Who's married?" Qi Yaoyao looked at him and asked.

"Qin Laowu's nephew, switch to the one." Shen Zhouheng looked up at her and said.

"Ah! What do you think?" Qi Yaoyao frowned and looked at him and said, "I'm not afraid that the Qin sister will be bullied!"

"After such a long time, it should be the result of a calm discussion." Shen Zhou looked at her and said, "After they get married, they will still be pointed out by others. Few men don't care about themselves. If your daughter-in-law is dismissed from your relatives, you can imagine the life after marriage. Men don’t care, there are so many women in the world, why should a man be without a wife.”
