一、排烟罩的重要作用

1、 The important role of smoke exhaust hood

1.净化空气，保障健康

1. Purifying the air and ensuring health

酒店厨房在烹饪过程中会产生大量油烟、异味和有害气体，如不及时排出，会迅速弥漫整个厨房，恶化室内空气质量。排烟罩能在第一时间捕捉这些污染物，通过管道输送至室外，有效降低厨房内可吸入颗粒物、油烟气溶胶等有害物质的浓度，为厨师创造一个清新、健康的工作环境，减少因长期接触油烟而引发呼吸道疾病的风险。

The hotel kitchen generates a large amount of oil fumes, odors, and harmful gases during the cooking process. If not discharged in a timely manner, they can quickly spread throughout the kitchen, deteriorating indoor air quality. The exhaust hood can capture these pollutants in the first time and transport them to the outside through pipelines, effectively reducing the concentration of harmful substances such as inhalable particles and oil fume aerosols in the kitchen, creating a fresh and healthy working environment for chefs, and reducing the risk of respiratory diseases caused by long-term exposure to oil fume.

2.防止油烟沉积，保护设备

2. Prevent oil fume deposition and protect equipment

油烟具有黏性，极易附着在厨房的墙壁、天花板、设备表面。若不加以控制，长时间积累的油烟会形成厚厚的油垢，不仅影响厨房的美观，还会腐蚀设备，缩短其使用寿命。排烟罩强大的吸烟能力可大幅减少油烟在厨房内的沉积，保护炉灶、烤箱、蒸箱等厨房设备，降低设备维护成本，确保设备始终处于良好运行状态。

Oil fume is sticky and easily adheres to the walls, ceilings, and equipment surfaces in the kitchen. If not controlled, the accumulated oil fumes over a long period of time will form thick oil stains, which not only affect the appearance of the kitchen, but also corrode equipment and shorten its service life. The powerful smoking ability of the exhaust hood can significantly reduce the deposition of oil fumes in the kitchen, protect kitchen equipment such as stoves, ovens, and steamers, reduce equipment maintenance costs, and ensure that the equipment is always in good operating condition.

3.降低火灾风险

3. Reduce the risk of fire

厨房是火灾高发区域，而油烟积累是引发火灾的重要隐患之一。大量油烟附着在设备和管道表面，遇到明火或高温时极易燃烧。排烟罩通过及时排出油烟，减少了厨房内的易燃物，有效降低了火灾发生的概率，为酒店的消防安全提供有力保障。

The kitchen is a high-risk area for fires, and the accumulation of oil fumes is one of the important hidden dangers that can cause fires. A large amount of oil fumes adhere to the surfaces of equipment and pipelines, making them highly flammable when exposed to open flames or high temperatures. The smoke exhaust hood reduces the flammable materials in the kitchen and effectively lowers the probability of fire by timely discharging oil fumes, providing strong protection for the hotel's fire safety.

二、维护与保养

2、 Maintenance and upkeep

1.日常清洁不可少

1. Daily cleaning is essential

酒店厨房工作人员每天营业结束后，应及时对排烟罩进行清洁。先用湿布擦拭排烟罩表面，去除油污和灰尘，对于顽固污渍，可使用专用的厨房油污清洁剂进行清洗。同时，要清理集油盒内的油污，防止集油过多溢出。油烟净化器的滤网和电极也需定期清洗，一般每周或每半个月清洗一次，以保证净化效果。

The hotel kitchen staff should clean the smoke exhaust hood in a timely manner after the end of business every day. First, wipe the surface of the exhaust hood with a damp cloth to remove oil stains and dust. For stubborn stains, use a specialized kitchen oil stain cleaner for cleaning. At the same time, it is necessary to clean the oil stains inside the oil collection box to prevent excessive oil spillage. The filter and electrodes of the oil fume purifier also need to be cleaned regularly, usually once a week or every half a month, to ensure the purification effect.

2.定期检查保运行

2. Regularly check and ensure operation

定期对排烟罩、管道和风机进行全面检查。检查排烟罩的结构是否稳固，有无变形、损坏；查看管道内是否有油污积聚，如有需要，可使用专业的管道清洗设备进行清理；检查风机的叶片是否有油污附着，电机运行是否正常，如有异常噪音或振动，要及时维修或更换部件。此外，还要检查油烟净化器的净化效果，如发现净化效率下降，要及时查找原因并进行处理。

Regularly conduct comprehensive inspections of smoke exhaust hoods, pipelines, and fans. Check whether the structure of the smoke exhaust hood is stable, free from deformation or damage; Check whether there is oil accumulation in the pipeline, and if necessary, use professional pipeline cleaning equipment for cleaning; Check whether the blades of the fan have oil stains attached, and whether the motor is running normally. If there is any abnormal noise or vibration, repair or replace the components in a timely manner. In addition, it is necessary to check the purification effect of the oil fume purifier. If a decrease in purification efficiency is found, the cause should be promptly identified and dealt with.

3.专业维护更放心

3. Professional maintenance is more reassuring

对于复杂的排烟系统，建议定期聘请专业的清洁维护公司进行深度保养。专业人员具备专业工具和技术，能够对排烟罩内部结构、管道深处进行彻底清洁，同时对系统进行全面检测和调试，确保排烟系统始终处于最佳运行状态。一般每季度或半年进行一次专业维护，可有效延长排烟系统的使用寿命，保障其稳定运行。​​

For complex smoke exhaust systems, it is recommended to regularly hire a professional cleaning and maintenance company for in-depth maintenance. Professional personnel possess specialized tools and techniques to thoroughly clean the internal structure and deep pipes of the smoke exhaust hood, while conducting comprehensive testing and debugging of the system to ensure that the smoke exhaust system is always in optimal operating condition. Generally, professional maintenance is carried out once every quarter or six months, which can effectively extend the service life of the smoke exhaust system and ensure its stable operation. ​​
