Description

Technical Field

[0001] This utility model relates to the technical field of kitchen exhaust fans, specifically a commercial centrifugal cabinet-type kitchen exhaust fan. Background Technology

[0002] Centrifugal cabinet-type range hoods are devices specifically designed for kitchen fume extraction. They utilize the principle of centrifugal force, using a rotating impeller to separate oil fumes from the air and exhaust them outdoors. Centrifugal fans can generate high wind pressure and air volume, effectively removing oil fumes and odors from the kitchen. They employ advanced noise reduction technology and materials, resulting in low noise during operation and minimizing disruption to daily life.

[0003] The filters in centrifugal cabinet-type range hoods need to be cleaned regularly to maintain the normal operation and hygiene of the range hood. However, common filters are fixed with bolts, and over time, grease buildup makes the bolts difficult to remove, making filter cleaning very difficult and potentially requiring professional disassembly and cleaning. The accumulated grease on the filter will clog the mesh, reducing the exhaust efficiency of the range hood. As the grease buildup worsens, it will prevent the smoke from being discharged properly, affecting the environment and causing adverse effects on users. Therefore, we propose a commercial centrifugal cabinet-type range hood. Utility Model Content

[0004] Technical Problem Solved: Addressing the shortcomings of existing technologies, this utility model provides a commercial centrifugal cabinet-type range hood with advantages such as easy filter removal and installation. This commercial centrifugal cabinet-type range hood, through its designed filter removal and installation mechanism, makes filter disassembly and installation simpler and faster. Users can periodically remove the filter for cleaning, maintaining the cleanliness and efficient operation of the centrifugal cabinet-type range hood. Regular filter cleaning prevents grease buildup, reduces the burden on the equipment, and thus extends the range hood's lifespan. A clean filter ensures the range hood's suction power and smoke extraction effect, improving work efficiency. To maintain environmental cleanliness and hygiene, the control handle can be manually pulled upwards when disassembly is required, causing the positioning frame to be pulled out from the limiting groove and insertion port. The positioning frame is connected to the filter screen inside, and the positioning frame is engaged with the inner wall of the inner positioning port through the triangular positioning block and positioning triangular hole. During disassembly, the positioning frame can also be directly pressed downwards to disengage the triangular positioning block from the positioning triangular hole, thus detaching the positioning frame from the inner positioning port. The first and second sealing strips enhance the sealing of the positioning frame inside the insertion port and limiting groove, effectively solving the problems in the background technology.
