Chen Zhouheng looked at Qi Yaoyao in surprise and said, "Do you need it?"

"If you need it, it's convenient to connect the stove to use hot water." Qi Yaoyao stared at him and nodded hurriedly, "You want to go out to get hot water in the middle of winter!" He shivered and said, "Come and bring the food from the kitchen, isn't it cold?"

"I will discuss with Qin Laowu and set up a dirt stove here in the hall." Chen Zhou crossed out of the bedroom and looked at the hall and thought, "This dirt stove is only used in winter. If the weather is warm, you have to move it out."

"Of course, it will get hot in summer." Qi Yaoyao said with a smile when she heard this.

"I wonder how Qin Laowu's stove plate is like?" Chen Zhouheng said to himself.

"It should be possible! They all use this stove to sell it themselves." Qi Yaoyaojun said with dark eyes looking at him.

"If it's just a separate kang and a stove to be repaired, it will be a little troublesome to connect it." Chen Zhouheng looked at her with amber eyes and said seriously.

"Is this difficult?" Qi Yaoyao said in surprise, pointing to the wall and saying, "It's better if you just open it up."

"It's not that simple." Chen Zhouheng's deep eyes focused on her, "At the connection between the kang and the stove, we call it "throat" over there, it is a hyperbolic shape." Let go of her and gestured with her fingers.

"I understand." Qi Yaoyao smiled and nodded. He said like the cooling tower of the thermal power plant later, with a hyperbolic appearance.

Don’t underestimate this kang. The ancestors have such profound knowledge.

Chen Zhouheng looked at her and explained seriously, "The connection between the kang and the earth stove is entirely based on experience. The "throat" is left small. When there is no windy day, the smoke cannot be discharged; when there is a "throat" is left large. When there is a windy day, the kang is left large and the fireworks are pumped into the kang. The pot cannot be turned on for the time being and cannot be cooked."

I saw almost the view in this room, so I walked out.

"Where are you going, let me tell me!" Chen Zhouheng hurried over and helped her and said.

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

"What do you think of this?" Chen Zhou looked over her gaze.

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

"Haha..." Chen Zhouheng chuckled and said, "You are really worried."

"What are you laughing at?" Qi Yaoyao said with annoyance, "This is a very serious question."

"Yes, yes!" Chen Zhouheng nodded with a smile, "Then you should check out the internal structure of the kang."

Chen Zhouheng helped her into the bedroom again, pointing at the kang, "If the cold wall inside the kang is thin, it will be poorly insulated. In winter, the cold wall will be frost and ice will be hung, and the heat loss will be large. Also, the cold wall is not smeared tightly, and the air leakage will cause air to leak, and the kang will not be too hot no matter how hot it is."

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

"How is that possible?" Chen Zhouheng looked at her with a funny look and said, "It can be smoothed with mud, it is very smooth." The index finger pointed at the kang, "But the flow resistance of the smoke when it touches the bottom of the kang board is great, which affects the speed of smoke distribution and exhaust, and directly affects whether the kang surface is hot enough."

Gu Du

"Yeah!" Qi Yaoyao nodded gently.

"There are both special arrangements for the fire-watching bricks and wind-watching bricks in this kang. Improper placement will cause great resistance to smoke exhaust in the kang, resulting in poor smoke exhaust, and will cause uneven heat to the end of the kang and the end of the kang." Chen Zhou pointed at the head of the kang and the end of the kang and said.

"The kang hole, flue, and ash pit are too deep, and a measured air conditioner will accumulate in the kang. When the stove eye creates a fire, the air conditioner and hot smoke in the kang will be exchanged, creating a vortex, and the kang stove will be difficult to burn." Chen Zhouheng explained seriously.

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

"You will know when you cook when cooking." Chen Zhouheng tilted his head slightly and said, "The stove eyes are filled with firewood, and there is no gap, so there is definitely no lit."

Qi Yaoyao smiled and suddenly said, "Have you ever thought about why? Did you say that everyone is getting high in firewood!"

"I really thought about it. Maybe it's too crowded in a confined space!" Chen Zhouheng thought about it carefully and said, "Learn deeper..." he scratched his head and said, "It seems that he doesn't know."

Qi Yaoyao smiled when she heard this. Why are there so many people? Not so many people are exploring it.

"This kang is not so simple to smooth it out! Although this appearance does not require carving or something? But you have to decorate it a little! Especially the edge of this kang."

"Yes! The edge of this kang is covered with wood, using a whole piece of wood." Chen Zhou pointed at the edge of the kang and said, "The wood must flow directly, without scars and stubble, and the width and height must be moderate. The best kang is jujube wood, without jujube wood, and aquatic willows are fine. Ordinary people will use poplar or pine wood."

Her bright and translucent eyes looked at her and said, "If Yaoyao wants to have a stove, cook in winter, cook with fire, and the kang is hot. In summer, adobe blocks the eyes of the kang to prevent fire from entering. A kang without stove and a stove with a stove can not only heat the kang, but also use hot water."

Fortunately, the kang is only half-plating, and the exterior walls of the house that are close to the hall are not as good as it is, so overall modification is much easier.

The Qin family’s uncle and nephew are both honest people and work hard. They put on four kangs and a earthen stove, and it took half a month to complete it.

I rushed to earn some pocket money before the autumn harvest to supplement my family's income, and when I got home, I happened to catch up with the autumn harvest.

"Does this kang still need to be dried?" Qi Yaoyao said as she looked at the kang that was plated in the bedroom.

"Of course it's still tideful." Chen Zhouheng tilted his head slightly and looked at her and said.

"This baking will take at least ten days and half a month!" Qi Yaoyao looked at the fire kang with her lively eyes, "It's just before winter begins."

"Yeah!" Chen Zhouheng smiled and nodded, holding her and said, "Let's go! The taste in this room is not very good."

The two sat on the bamboo chair in the corridor, "I didn't expect to get married in the end." Chen Zhouheng murmured to himself.

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

"Qin Laowu's nephew, change to kiss that." Chen Zhouheng raised his eyes and looked at her and said.

"Ah! What do you think?" Qi Yaoyao frowned and said, "Are you not afraid that the Qin sister will be bullied!"
