　　廚房排煙罩的正確安裝方法包括以下幾個步驟：

　　The correct installation method for kitchen smoke exhaust hood includes the following steps:

　　確定安裝位置：?油煙罩應安裝在灶具的上方，?距離灶具約60-70厘米的距離。?這個距離可以保證油煙被有效排出，?同時避免安裝位置過低導致的安全隱患或安裝位置過高導致的排煙效果不佳。

　　Determine installation location: The oil fume hood should be installed above the stove, at a distance of about 60-70 centimeters from the stove. This distance can ensure effective exhaust of oil fumes, while avoiding safety hazards caused by low installation positions or poor smoke exhaust effects caused by high installation positions. 

　　選擇合適的尺寸：油煙罩的尺寸應與灶具的尺寸相匹配，以確保排風效果和節省空間。尺寸過小會導致排風不暢，影響使用效果；尺寸過大則可能浪費空間并增加不必要的能耗。

　　Choose the appropriate size: The size of the hood should match the size of the stove to ensure ventilation and save space. Being too small in size can lead to poor ventilation and affect the effectiveness of use; If the size is too large, it may waste space and increase unnecessary energy consumption. 

　　安裝排煙管道：確保排煙管道連接順暢，避免阻力過大影響排煙效果。如果排煙到共用煙道，應避免將排煙管插入過深；如果排煙到墻外，應確保排煙管口伸出足夠長度，?避免回灌。

　　Install smoke exhaust ducts: Ensure smooth connection of smoke exhaust ducts and avoid excessive resistance affecting smoke exhaust effectiveness. If the smoke is discharged into the shared flue, it should be avoided to insert the smoke exhaust pipe too deeply; If smoke is emitted outside the wall, it should be ensured that the smoke exhaust pipe extends a sufficient length to avoid backflow. ?

　　墻體強度要求：安裝油煙罩的墻體應具有足夠的強度。排煙管、風管的外墻開口可采用砌筑預制帶洞混凝土塊或預埋鋼管留洞方式。對于保溫墻，?建議使用空心磚，并確保安裝方法與正常墻壁相同。如果墻面不夠結實，應使用木板或其他材料進行加固。

　　Wall strength requirements: The wall where the oil fume hood is installed should have sufficient strength. The external wall openings of smoke exhaust pipes and air ducts can be constructed using precast concrete blocks with holes or pre embedded steel pipes with holes. For insulation walls, it is recommended to use hollow bricks and ensure that the installation method is the same as for normal walls. If the wall is not sturdy enough, wooden boards or other materials should be used for reinforcement. ?

　　排氣口設置：對于直接穿過外墻至室外的排煙方式，應在室外排氣口設置防止污染環境和避風的構件。共用豎向煙道連接的吸油煙機，?其豎向煙道的斷面應根據所負擔的排氣量計算確定。

　　Exhaust port setting: For smoke exhaust methods that directly pass through the exterior wall to the outside, components to prevent environmental pollution and shelter from wind should be installed at the outdoor exhaust port. The cross-section of the vertical flue of a range hood connected by a shared vertical flue should be calculated and determined based on the amount of exhaust carried. ?

　　注意事項： 在搬動和安裝過程中應輕拿輕放，避免沖擊碰撞。如有局部損傷，在不影響使用效果的前提下，可用水泥等材料進行修補。

　　Attention: Handle and install with care to avoid impact and collision. If there is local damage, it can be repaired with materials such as cement without affecting the effectiveness of use. ?

　　通過遵循上述步驟和注意事項，可以確保廚房排煙罩的正確安裝，從而有效排除廚房中的油煙和異味，保持廚房空氣的清新和健康。

　　By following the above steps and precautions, it is possible to ensure the correct installation of kitchen exhaust hoods, effectively removing oil fumes and odors from the kitchen, and maintaining fresh and healthy kitchen air.
