Description

Technical Field

[0001] This utility model belongs to the field of exhaust pipe technology, specifically relating to a stainless steel exhaust pipe structure. Background Technology

[0002] Hotel kitchens generate a lot of fumes and heat during cooking, requiring exhaust pipes to quickly remove these fumes and heat from the room and prevent them from spreading within the kitchen. There are various types of exhaust pipes, with stainless steel exhaust pipes being a common type. Stainless steel exhaust pipes have good corrosion resistance and can resist the erosion of acidic substances and moisture in fumes, making them less prone to rusting and deformation.

[0003] The hotel kitchen's range hood is connected to a stainless steel exhaust pipe. The fumes from the range hood are discharged through the stainless steel exhaust pipe. However, the stainless steel exhaust pipe connected to the range hood does not have a pre-filter function for fumes. Oil droplets in the fumes will adhere to and accumulate on the inner wall of the stainless steel exhaust pipe. With long-term use, this will affect the exhaust efficiency. In addition, the stainless steel exhaust pipe has fumes adhering to its inner wall, so cleaning requires removing the entire stainless steel exhaust pipe. It is not possible to clean fumes without completely disassembling the stainless steel exhaust pipe, which is a drawback.

[0004] Existing stainless steel exhaust pipes, when used with range hoods, have the problems of not being able to pre-filter large oil droplets in the exhaust gas and not being able to clean the fumes without completely disassembling the stainless steel exhaust pipe. To address these issues, this application proposes a stainless steel exhaust pipe structure. Summary of the Invention
