Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smoke exhaust duct sealing in building construction, in particular to a smoke exhaust duct anti-leakage structure surrounded by structures on three sides at the position of an upward-flipping bay window. Background Art
[0002] The flip-up bay window is a special window design with multiple functions and advantages. It not only increases the indoor storage space, but also serves as an ideal place for rest and work. This design usually includes a flip-up cover, which can effectively prevent dust and debris from entering the window sill, keeping the interior clean and tidy. There are many forms of flip-up bay window design, including flip-up storage, side vertical hidden storage and drawer design. The flip-up design can provide additional storage space without destroying the overall appearance. The side vertical hidden storage uses the side of the windowsill for storage, maintaining the beauty of the front while increasing the storage space. The drawer design adds a drawer cabinet at the bottom of the low bay window, providing a convenient storage solution.
[0003] The exhaust duct surrounded by three sides is a kind of design. Through the design of three sides, it effectively prevents the side leakage and escape of oil smoke and improves the exhaust effect. This design is different from the traditional smoke collection plate design. By adding side panels on the side, a triangular negative pressure zone is formed, thereby eliminating the oil smoke from leaking from the side of the range hood, improving the smoke collection effect and speeding up the efficiency of oil smoke absorption. The design principle of the exhaust duct surrounded by three sides is based on the formation of a negative pressure zone. The negative pressure zone of the traditional side-suction range hood is far away from the gas stove, and the oil smoke is easy to escape sideways during the rising process. The exhaust duct surrounded by three sides forms a downward negative pressure zone by adding smoke collection wings on both sides combined with the front smoke guide plate. The close-range negative pressure smoke collection effectively prevents the oil smoke from escaping sideways.
[0004] In modern architectural design, in order to improve living comfort and aesthetics, many residences have adopted the design concept of upturned bay windows. Ordinary flues are set in sections at the position of the floor slabs on each floor and installed one section at a time. In order to ensure airtightness and safety, the gap between the flue and the floor slab is filled with concrete to achieve sealing. The splicing of multiple flue sections can adapt to changes in building structures. Although it is highly flexible, there is a risk of leakage due to loose joints in actual operation. It is incapable of enclosing areas on three sides of the structure in a small space and cannot effectively solve the sealing problem in this area. Utility Model Content
