Description

Technical Field

[0001] The utility model relates to the field of building exhaust ducts, in particular to an assembled residential kitchen and bathroom exhaust duct and an exhaust duct system. Background Art

[0002] The kitchen and bathroom exhaust ducts of prefabricated houses are usually arranged in the corners of kitchens or bathrooms in multi-story buildings. They are used for the centralized discharge of kitchen smoke and bathroom waste gas. The kitchen fumes and waste gas are collected through the exhaust duct and then discharged from the roof hood. Most of the existing kitchen and bathroom exhaust ducts use hollow square mortar pipes and artificially pasted double-tube exhaust ducts. Their lateral impact resistance is weak. The strength can only be improved by increasing the wire diameter of the steel mesh to achieve impact resistance. If the fire check valve installed on the pipeline is stuck by oil and dirt, it will cause the valve plate to be not closed tightly. If a fire occurs downstairs, the flames will extend along the pipeline and cause the upper kitchen to burn and catch fire. In particular, the smoke and odor are serious, causing indoor air pollution, which directly endangers personal safety and health. Some double-tube exhaust ducts are mostly made of artificial paste, with uneven wall thickness, insufficient ventilation cross-sectional area, and the uniformity of smoke emission cannot be guaranteed. After installation, it is easy to cause the tiles pasted on for secondary decoration to jump corners or fall off. Due to the small ventilation area, when the exhaust pressure is high, it is easy to cause the kitchen range hood to be blocked. Over time, it is easy to damage the appliance and cause economic losses. When the above two exhaust ducts were installed on the construction site, the installation technology was too rough. The traditional method of sealing the joints of the two floors would cause smoke leakage and odor due to poor air tightness, and the defect problem was more prominent.

[0003] The ground floor of some existing residential buildings is designed as a commercial base. According to the standard requirements, the commercial base must be designed with a separate exhaust duct. However, there are still a small number of commercial bases in some places that share an exhaust duct with residential buildings, such as some old residential areas in the past, or shops that have been renovated privately. Because merchants have to redesign an exhaust duct, the cost is high, and the exhaust duct can only be designed to the outside of the house, which is very unsightly. In order to save costs, some shops only extend their exhaust ducts outside the shops, and do not lay them vertically to the roof, so the exhaust smoke often makes the residents upstairs complain. The main reason why a set of exhaust ducts cannot be shared is that the existing shops such as restaurants, hot pot restaurants, and barbecue restaurants have a large exhaust volume and a long exhaust time when they are open. It is easy for smoke and smell to pass through the exhaust duct, and it will greatly increase the load of the exhaust duct, causing problems with the exhaust duct of the users upstairs. Therefore, only finished commercial exhaust ducts can be added, which are costly, have a great impact, and are not beautiful. Even if a group of exhaust ducts are shared, it is impossible to distribute and design the exhaust ducts according to the size of the exhaust volume during installation design. Utility Model Content

[0024] The utility model will be further described below, specifically as follows: an assembled residential kitchen and bathroom exhaust duct and exhaust duct system, see Figure 1 to Figure 2, including an exhaust duct 1, wherein a Y-shaped vertical partition 2 is arranged in the exhaust duct 1. The utility model designs a Y-shaped vertical partition 2 in the exhaust duct 1. The Y-shaped vertical partition 2 can increase the overall structural stability of the exhaust duct 1, improve the structural strength of the exhaust duct 1, and make it meet the requirements of the anti-flexible impact index, which is more conducive to the processing and design of the large-diameter exhaust duct 1. Moreover, the exhaust duct 1 is divided into a left main exhaust duct 3, a right main exhaust duct 4 and a central triangular auxiliary exhaust duct 5 by the vertical partition 2. The auxiliary exhaust duct 5 serves as an independent exhaust channel for each floor, and discharges the smoke and waste gas generated by the kitchen and bathroom into the main exhaust duct. The main exhaust duct is divided into two independent main exhaust ducts by the Y-shaped vertical partition 2. The left main exhaust duct 3 and the right main exhaust duct 4 are independently exhausted and do not affect each other. When installing and designing the exhaust duct 1, the auxiliary exhaust duct 5 discharge channel of each floor can be designed according to needs.

[0025] The Y-shaped vertical partition 2 has the following advantages: 1. It increases the strength of the exhaust duct 1. During the final tiling and secondary decoration, it will not be damaged even if it is subjected to external impact or collision. 2. The hollow cylinder exhaust duct 1 is a thin-skinned pipe fitting. Due to the shrinkage of cement, the cracking of the pipe is very serious during the pouring production. The designed Y-shaped vertical partition 2 can make it more structurally sound, less prone to cracking, with a high qualified rate of finished products, which is more conducive to processing and production. 3. After the exhaust duct 1 is separated, the uniformity of the smoke in the duct is increased, and the problem of smoke and odor between floors can be solved.

[0026] When designing the exhaust duct for a purely residential high-rise building, the auxiliary exhaust duct 5 on half of the floors can be connected to the left main exhaust duct 3, and the auxiliary exhaust duct 5 on the other half of the floors can be connected to the right main exhaust duct 4. Since the left main exhaust duct 3 and the right main exhaust duct 4 are exhausted independently, the exhaust capacity of the main exhaust duct is greatly increased, and the mutual influence of exhaust between floors is reduced to half of the original.

[0027] When designing the exhaust duct shared by ground floor shops and residences, if the auxiliary exhaust duct 5 on the ground floor shop is connected to the left main exhaust duct 3, the left main exhaust duct 3 and the right main exhaust duct 4 can be allocated according to the daily ventilation volume, and the auxiliary exhaust duct 5 connected to the left main exhaust duct 3 on the upper floor can be reduced proportionally. This can reduce the exhaust load and the impact of commercial exhaust on the exhaust of the auxiliary exhaust duct 5 of the residents upstairs.

[0028] The exhaust duct 1 is provided with an exhaust valve installation port 6 which is connected to the auxiliary exhaust duct 5. An exhaust non-return valve is installed at the exhaust valve installation port 6, and the exhaust pipe of the range hood or exhaust fan is connected to discharge the indoor smoke and waste gas into the auxiliary exhaust duct 5. The vertical partition 2 in the auxiliary exhaust duct 5 is provided with an exhaust port 8 which is connected to the left main exhaust duct 3 or the right main exhaust duct 4. The smoke in the auxiliary exhaust duct 5 can be discharged into the corresponding main exhaust duct through the exhaust port 8. The exhaust port 8 is provided with an air guiding baffle 7 which plays a role of guiding wind. The air guiding baffle 7 is located at the exhaust port 8 to play a role of guiding wind and at the same time separate the auxiliary exhaust ducts 5 on each floor.

[0029] The air guide baffle 7 is horizontally arranged in the auxiliary exhaust duct 5, and the auxiliary exhaust duct 5 is divided into independent upper and lower auxiliary exhaust ducts by the air guide baffle 7. The setting of independent exhaust ducts can effectively avoid the influence of smoke between floors, and can prevent the smoke downstairs from entering the rooms upstairs through the exhaust duct 1, effectively avoid smoke odor, and prevent the flame from spreading to the rooms upstairs in case of fire.

[0030] The air guide baffle 7 is arranged above the exhaust port 8 and is inclined upward along the exhaust direction of the exhaust port 8. During exhaust, the smoke enters the auxiliary exhaust duct 5 from the exhaust valve, and the smoke in the auxiliary exhaust duct 5 moves upward, is blocked by the air guide baffle 7, and is guided to the exhaust port 8 to exhaust, and then enters the left main exhaust duct 3 or the right main exhaust duct 4, and moves upward along the main exhaust duct until it is discharged from the wind hood 13 at the top of the exhaust duct 1.

[0031] Since the existing exhaust duct 1 is basically arranged in a top exhaust manner, in order to optimize the arrangement of the exhaust valve mounting port 6, the exhaust port 8 and the air guide baffle 7 and facilitate their processing and manufacturing, the exhaust valve mounting port 6 and the exhaust port 8 are both opened in the upper part of the exhaust duct 1, the exhaust port 8 is located below the exhaust valve mounting port 6, and the air guide baffle 7 is located between the exhaust valve mounting port 6 and the exhaust port 8. The exhaust valve mounting port 6 in the exhaust duct 1 on this floor is used as the exhaust duct on this floor. When the smoke enters the auxiliary exhaust duct 5, it will follow the auxiliary exhaust duct 5 into the auxiliary exhaust duct 5 of the exhaust duct 1 on the upper floor, be blocked by the air guide baffle 7 and guided to the exhaust port 8, and be discharged into the corresponding main exhaust duct from the exhaust port 8.

[0032] The exhaust duct 1, the vertical partition 2 and the air guide partition 7 are integrally cast by a mold, which is simple and convenient to manufacture and has high structural strength. The exhaust duct 1 is square, and a chamfered structure 9 is cast on the inner corner of the exhaust duct 1, and the chamfered structure 9 can increase the structural strength of the four corners of the square exhaust duct 1. The connection between the vertical partition 2 and the exhaust duct 1 is cast with a chamfered structure 9, and the chamfered structure 9 can enhance the structural strength of the connection between the vertical partition 2 and the exhaust duct 1.

[0033] Since each set of exhaust ducts 1 is installed on the corresponding floor, there is a floor between the floors, and the floor will open an exhaust duct installation port at the installation location of the exhaust duct 1. In order to achieve better docking of the exhaust duct 1 on the upper floor, it is necessary to use an exhaust pipe connecting sleeve 10 for connection and fixing. In order to achieve better docking of the exhaust duct 1 of the utility model, a matching exhaust pipe connecting sleeve 10 is designed, see Figure 3 The shape of the exhaust pipe connection sleeve 10 is the same as the cross-sectional shape of the exhaust pipe 1, and the upper and lower end surfaces are provided with slots matching the exhaust pipe 1. The exhaust pipe connection sleeve 10 is provided with a connector and a slot having the same cross-sectional shape as the vertical partition plate. The connection and fixation of the upper and lower exhaust pipes 1 are realized by the exhaust pipe connection sleeve 10. The left and right sides of the exhaust pipe connection sleeve 10 are processed with flanged grooves 11 for installing transverse positioning steel bars 12. The flanged grooves 11 are formed by cutting and folding and are erected on the exhaust duct installation port. After the exhaust pipe connection sleeve 10 is installed, a group of steel bars 12 are erected horizontally on it. The steel bars 12 press the flanged grooves 11. The exhaust pipe connection sleeve 10 is positioned on the floor slab of the exhaust duct installation port, and then the exhaust pipe 1 is lifted to the exhaust pipe connection sleeve 10 for docking, so as to realize the docking of the upper and lower exhaust pipes 1. The exhaust pipe connection sleeve 10 can be a separate accessory, or it can be integrally cast on the top of the exhaust pipe 1, so that the exhaust pipe connection sleeve 10 is used as a hanging point to lift the entire exhaust pipe 1 for installation.

[0034] An assembled residential kitchen and bathroom exhaust duct system, see Figure 4 The exhaust duct system is composed of multiple groups of exhaust pipes 1, which are arranged in sequence along the vertical direction. Each group of exhaust pipes 1 is arranged on the floor slab of each floor. The exhaust pipes 1 are positioned and connected by exhaust pipe connecting sleeves 10. By connecting and arranging the multiple groups of exhaust pipes 1 in the vertical direction, a complete assembled residential kitchen and bathroom exhaust duct system is formed.

[0035] Preferably, the secondary exhaust duct 5 is connected with the left main exhaust duct 3 and the right main exhaust duct 4 in a staggered manner from top to bottom. For example, the left main exhaust duct is used uniformly on the odd-numbered floors, and the right main exhaust duct is used uniformly on the even-numbered floors. The staggered exhaust method greatly reduces the impact of smoke exhaust between adjacent floors.

[0036] The above is a detailed introduction to an assembled residential kitchen and bathroom exhaust duct and exhaust duct system provided by the utility model. Specific examples are used in this article to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model; at the same time, for general technical personnel in this field, according to the idea of ​​the utility model, there will be changes in the specific implementation method and application scope, and changes and improvements to the utility model will be possible without exceeding the concept and scope specified in the attached claims.
