　　如果油煙機是每天都開，而且油煙只從一個煙道出去，時間一長很快就會積滿油污的，兩三個月就已經能積起比較厚的一層油，有一指多厚，不及時對油煙機進行清洗，將會對正常使用產生較大的阻礙。

　　If the range hood is turned on every day and the oil fumes only go out from one flue, they will quickly accumulate oil stains over time. Within two or three months, a thick layer of oil can already accumulate, which is over a finger thick. If the range hood is not cleaned in time, it will cause significant obstacles to normal use.

　　因為怕出現煙道著火的事故，所以我們平時就經常把油煙管道清洗一下，把通煙口百葉窗的油洗掉，經常清洗，這樣可能就會避免事故。所以這個具體看你這邊的實際情況。也是根據當地消防部門要求定期清洗，如果是不太清楚，可以咨詢我們藝源環保來公司幫你免費檢測油煙機是不是需要清洗。

　　Because we are afraid of accidents such as flue fires, we often clean the oil fume ducts, wash off the oil from the louvers of the smoke vent, and clean them regularly to avoid accidents. So it depends on the actual situation on your end. It is also required by the local fire department to clean regularly. If you are not sure, you can consult our Yiyuan Environmental Protection company to help you check for free whether the range hood needs to be cleaned.

　　There are significant differences in cleaning solutions for different oil fume ducts, and the results after cleaning also vary. Specific recommendations from professionals can be consulted.

　　一、油煙管道清洗的介紹

　　1、 Introduction to cleaning oil fume ducts

　　油煙管道不經常清洗，會有很多油漬殘留在煙機上和油煙管道表面，時間久了會形成油垢，簡單的油煙管道清洗是處理不掉的，這樣會影響油煙機、油煙管道清洗的使用，使煙流不易排除。

　　If the oil fume duct is not cleaned regularly, there will be a lot of oil stains remaining on the hood and the surface of the oil fume duct. Over time, oil stains will form. Simple cleaning of the oil fume duct cannot remove them, which will affect the use of the hood and oil fume duct cleaning and make it difficult to remove the smoke flow.

　　８０％左右的廚房排煙不暢，主要原因都是由于長時間沒有對油煙凈化器的內置過濾網清潔而而造成，油污堵塞過濾網而造成的，針對不同類型的油煙凈化器有獨特的方法。采用高壓射流強力化油劑，對油煙管道清洗進行除油處理后，再做保養，使油煙氣流明顯好轉，并形成保護膜使油漬不易殘留在表面。

　　About 80% of kitchens have poor smoke exhaust, mainly due to long-term lack of cleaning of the built-in filter screen of the oil fume purifier, which is caused by oil pollution blocking the filter screen. There are unique methods for different types of oil fume purifiers. Using high-pressure jet powerful oil refining agent, after cleaning the oil fume pipeline and removing oil, maintenance is carried out to significantly improve the oil fume airflow and form a protective film to prevent oil stains from remaining on the surface.

　　油煙管道清洗內容包括煙罩表面、煙罩內的燈罩、排風口、排煙口以及電機、灶臺表面。油煙管道清洗清洗的重點是排煙口與煙罩相連處并和煙罩同步平行的排油煙管道清洗。重點對平行油煙管道內部進行徹底清潔。采用的主要方法是專業人員進入油煙管道清洗內部進行清潔。對于排煙口窄小，人工無法進入油煙管道或由于油煙管道走身狹窄、人工觸及不到無法進行清潔，但又存在著重大隱患的，本公司可利用特殊設備進行清潔，不留死角，并可拍攝清潔前后的對比照片，打消客戶的疑慮和擔心，消除一切潛在的火災隱患。

　　The cleaning of oil fume ducts includes the surface of the hood, the lampshade inside the hood, the exhaust outlet, the smoke exhaust outlet, as well as the surface of the motor and stove. The key to cleaning the oil fume duct is to clean the exhaust duct that is connected to the smoke hood and runs parallel to the smoke hood. Focus on thoroughly cleaning the interior of parallel oil fume ducts. The main method used is for professionals to enter the oil fume duct and clean the interior. For narrow smoke exhaust outlets that cannot be manually entered into the oil fume duct, or for oil fume ducts that are too narrow to be manually touched and cannot be cleaned, but still pose significant risks, our company can use special equipment for cleaning, leaving no blind spots, and can take comparative photos before and after cleaning to dispel customers' doubts and concerns and eliminate all potential fire hazards.

　　風機、風柜與油煙管道連接的方法一般有兩種情況：一種是用帆布相連的軟連接，而另一種是直接與油煙管道相連的硬連接。可提供更換風機、風柜連接帆布的服務。如果是油煙管道硬連接，我們將與風機、風柜相連的油煙管道進行徹底清潔。

　　There are generally two methods for connecting fans, cabinets, and oil fume ducts: one is a soft connection using canvas, and the other is a hard connection directly connected to the oil fume duct. We can provide services for replacing fans and connecting canvas to wind cabinets. If it is a hard connection of the oil fume duct, we will thoroughly clean the oil fume duct connected to the fan and cabinet.

　　二、油煙管道清洗方法

　　2、 Cleaning methods for oil fume ducts

　　1、油煙管道清洗方法二：人工進入

　　1. Method 2 for cleaning oil fume ducts: manual entry

　　這種方法適用于大于40公分的平行煙道，人工鉆進去清洗，該方法勞動強度比較大，要注意通風及配備低壓照明用具。

　　This method is suitable for parallel flues larger than 40 centimeters, which can be manually drilled in for cleaning. This method has a relatively high labor intensity and requires attention to ventilation and the provision of low-pressure lighting fixtures.

　　2、油煙管道清洗方法三：拆卸

　　2. Oil fume duct cleaning method three: disassembly

　　當人工沒有辦法進入油煙管道時可采用拆卸法。這個方法是清洗最徹方法，但是施工難度比較大，需要的人工也很多，費用高。技術人員先根據煙道的實際情況，測算出拆卸的距離差，再兩邊延伸清潔。

　　When manual access to the oil fume duct is not possible, the dismantling method can be used. This method is the most thorough cleaning method, but the construction difficulty is relatively high, requiring a lot of labor and high cost. Technicians first calculate the distance difference for disassembly based on the actual situation of the flue, and then extend cleaning on both sides.

　　3、油煙管道清洗方法一：開孔

　　3. Method 1 for cleaning oil fume ducts: opening holes

　　這個方法比較容易，費用也比較低。需要技術人員先測算出需要開孔的間隔距離，開孔位置，開孔大小和開孔數量，再通過這些孔對油煙管道內進行清洗，最后再密封每個孔。開孔法是在人工法和拆卸法都無法清洗的時候用的。

　　This method is relatively easy and cost-effective. Technicians need to first measure and calculate the spacing distance, position, size, and quantity of openings required, and then clean the inside of the oil fume duct through these holes. Finally, seal each hole. The perforation method is used when neither manual nor disassembly methods can clean it.

　　4、油煙管道清洗方法四：機器設備清洗

　　4. Method 4 for cleaning oil fume ducts: Cleaning of machinery and equipment

　　人工不能進入，不方便拆卸，油污比較少，清洗周期較短的油煙管道可以用這個方法，這個方法難度最小，容易操作，且工作量最小，費用最低。在管道內噴灑清洗劑，油污軟化后，再電動軟軸刷刷干凈。

　　This method can be used for oil fume ducts that cannot be manually entered, are inconvenient to disassemble, have less oil pollution, and have a shorter cleaning cycle. This method is the least difficult, easy to operate, requires the least amount of work, and has the lowest cost. Spray cleaning agent inside the pipeline, soften the oil stains, and then clean them with an electric soft shaft brush.

　　5、油煙管道清洗方法五：空降

　　5. Cleaning method five for oil fume ducts: airborne

　　這個方法主要適用于清洗50公分以上的豎油煙管道。管道的最上截和最下截先由技術人員拆開，技術人員系著安全繩從上而下清洗煙道內的污垢。這個方法比較危險，技術要求高，費用高，但清洗效果好。

　　This method is mainly suitable for cleaning vertical oil fume ducts over 50 centimeters. The top and bottom sections of the pipeline are first opened by technicians, who wear safety ropes to clean the dirt inside the flue from top to bottom. This method is quite dangerous, with high technical requirements and high costs, but the cleaning effect is good.

　　三、清潔必要性：

　　3、 The necessity of cleaning:

　　煙道、煙罩常年處于高溫工作環境，油煙氣化形成積油、積炭或油膩的膠狀物，這三種物質非常容易引起火災。若不經常清洗，積油越積越多，順著煙罩自然倒流，不僅影響飯菜質量，而且還有損酒店信譽。同時，煙道中易寄生老鼠、蟑螂，不符合國家衛生標準。油膩膠狀物長期扒附在金屬表面，還會腐蝕金屬材料，縮短煙道使用壽命。所以要定時進行油煙管道清洗，以免發生火災危險。

　　Smoke ducts and hoods are exposed to high temperatures all year round, and the gasification of oil fumes can form oily, carbonaceous, or greasy gelatinous substances, which can easily cause fires. If not cleaned regularly, the accumulated oil will accumulate more and more, flowing back naturally along the hood, which not only affects the quality of the food, but also damages the hotel's reputation. Meanwhile, the smoke ducts are prone to parasitizing mice and cockroaches, which does not meet national hygiene standards. Long term adhesion of oily and sticky substances to metal surfaces can corrode metal materials and shorten the service life of the flue. So it is necessary to regularly clean the oil fume ducts to avoid the risk of fire.
