Description

Technical Field

[0001] The utility model relates to the field of smoke baffle assembly and disassembly structures, in particular to a range hood with a smoke baffle assembly that is easy to disassemble. Background Art

[0002] Range hoods, due to long-term exposure to oil smoke, will accumulate a lot of oil on the smoke shield, which needs to be disassembled and cleaned regularly. Therefore, whether the smoke shield assembly of the range hood is easy to disassemble and assemble has become a core concern of users. At present, there are many common ways to disassemble and assemble the smoke shield of range hoods on the market, such as screw fixing, magnetic suction, metal lock, etc., but these disassembly and assembly methods have their own disadvantages. The screw-fixed smoke shield disassembly and assembly method has the problems of difficulty in disassembly and low installation efficiency when it is covered with oil stains; the magnetic suction smoke shield disassembly and assembly method, on the one hand, after long-term use, the magnetic force will gradually weaken to a level lower than the lateral force caused by the gravity of the smoke shield, causing the smoke shield to fall off; on the other hand, the magnetic suction disassembly and assembly method is expensive and inconvenient to assemble; the metal lock type has a more complex structure and high cost.

[0003] For example, the Chinese utility model patent with the authorization announcement number CN203215781U, entitled "A smoke guide plate assembly for a range hood", discloses: comprising a smoke guide plate (1) and a range hood housing (4), wherein the upper end of the smoke guide plate (1) is provided with a hook (2), the lower end of the smoke guide plate (1) is fixed with a column (3) by welding, the range hood housing (4) is provided with a fixed shaft (5) and a magnetic hole (6), the hook (2) is hung on the fixed shaft (5) of the range hood housing (4), and the column (3) is inserted into the magnetic hole (6) of the range hood housing (4). The technical solution described in the utility model adopts both a magnetic attraction method and a hook combination method, which is costly and has a complex structure.

[0004] For another example, the Chinese utility model patent with authorization publication number CN215112810U, entitled "A Range Hood with a Removable Smoke Shield," discloses: It includes a range hood body and a smoke shield detachably mounted to the bottom of the range hood body. One end of the smoke shield is detachably and rotatably mounted to the range hood body via a hanging assembly, and the other end of the smoke shield is detachably mounted to the range hood body via a snap assembly. The hanging assembly includes a hook slot and a hook that can be snapped into the hook slot. The hook and the hook slot are respectively disposed on the bottom of the range hood body and the back of the smoke shield. The snap assembly includes a snap and a hook that snaps and secures with the snap. The snap and the hook are respectively disposed on the bottom of the range hood body and the back of the smoke shield. The technical solution described in this utility model uses both a hook connection method and a snap fastening method, resulting in a complex structure and high cost.

[0005] Finally, the Chinese utility model patent with the authorization announcement number CN212227163U and the title of intelligent mechanical electrostatic smoke hood integrated oil fume purifier discloses: comprising a cover shell (1) and a smoke filter chamber (2) installed on the top of the cover shell (1), the bottom of the housing (1) is provided with a smoke inlet, and the top is provided with a smoke outlet connected to the smoke filter chamber (2), the inner top of the cover shell (1) is provided with a plurality of filter devices (6) connected to the smoke outlet, the smoke inlet is inclined and a hanging plate (3) is provided on the top thereof, the front end of the hanging plate (3) is fixedly connected to a hanging strip (3a) along its length direction, the bottom of the smoke inlet is provided with a support plate (4), the smoke inlet is detachably provided with a baffle (5) for blocking the filter device (6), the upper end of the baffle (5) is provided with a hook portion for hanging the hanging strip (3a), the baffle The plate (5) is inclined and its lower part rests on the support plate (4). A limiting groove (4a) is provided at each end of the support plate (4) for the two sides of the baffle (5) to pass through. The hanging plate (3) is evenly spaced along its length with a plurality of main smoke inlet holes (3b). The support plate (4) is evenly spaced along its length with a plurality of auxiliary smoke inlet holes (4b). A water collecting trough (7) is provided at the bottom of the cover shell (1). A drainage outlet is provided at the bottom of the water collecting trough (7). A side plate (8) that can block the side edge of the baffle (5) is fixedly connected to the inner wall of the cover shell (1) on both sides of the smoke inlet. The bottom end of the side plate (8) extends to the top of the water collecting trough (7). A filter unit, an exhaust fan (2a) and a smoke outlet (2b) are sequentially provided in the smoke filter chamber (2) along the direction of smoke flow. The technical solution of the utility model only adopts a combination of a hanging plate (3) and a hanging strip (3a), but the lower part of the other end of the hanging plate (3) still abuts against the support plate (4) and a limiting groove (4a) is provided on the support plate (4). Although the structure is simplified, the smoke barrier in this solution cannot serve the purpose of placing kitchen utensils, etc., and has a single function and low structural stability.
