An air outlet of the air outlet cover faces downwards; the air blower can blow air towards the air outlet of the air outlet cover through the air supply channel, and air curtains are formed on the two opposite sides of the movable panel. According to the utility model, by virtue of a three-side shielding structure of the double air curtains and the turnover movable panel, an oil smoke overflow path of the smoke cage cavity can be effectively blocked, and a three-dimensional airtight blocking area is formed by matching with the air curtains, so that the movable panel and the lower side of the case form a flat surface in a closed state, and the flat surface can be flush with the lower side of an upper cabinet without leakage; and the overall visual effect of the ceiling type range hood is improved.

Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a top-mounted range hood with a smoke-drafting structure. Background Technology

[0002] Traditional top-mounted range hoods are installed vertically above the cooktop. They use a high-speed motor system to create a negative pressure zone and utilize aerodynamic principles to draw in cooking fumes, aerosols, and harmful gases through the smoke collection chamber. After the grease is separated by a multi-layer filtration system, the fumes are discharged outdoors.

[0003] However, in existing top-mounted range hoods, when the plume of cooking fumes rises to the collection area, boundary layer separation causes the vortex zone to expand, resulting in some oil fume particles bypassing the edge of the collection chamber and spreading to the cabinet walls and ceiling area. Range hoods need to be partially exposed inside the cabinets to prevent grease from entering the cabinet interior; however, exposed installation disrupts the visual integrity of the kitchen space. Therefore, further improvements are needed. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a top-mounted range hood with a wind curtain smoke-enclosing structure.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a top-suction range hood with a wind curtain smoke-enclosing structure, including: a casing, a fan cabinet, a fan assembly, a movable panel, a flip assembly, and a wind curtain assembly;

[0006] The fan assembly is disposed on the air handling unit; the air handling unit is located above the chassis; the chassis is provided with an oil fume adsorption chamber and a smoke trapping chamber; an air inlet is provided between the oil fume adsorption chamber and the smoke trapping chamber; the movable panel is provided below the smoke trapping chamber; the flipping assembly can flip the movable panel relative to the front side of the chassis to cover or open the smoke trapping chamber.

[0007] The air curtain assembly includes a blower, an air supply duct, and an air outlet hood; two air outlet hoods are provided and arranged in a long strip on opposite sides of the smoke cage; the air outlet of the air outlet hood faces downward; the blower can blow air through the air supply duct toward the air outlet of the air outlet hood to form an air curtain on opposite sides of the movable panel.

[0008] Optionally, the cross-section of the air outlet shroud has a tower-like structure with components expanding from top to bottom.

[0009] Optionally, the air outlet of the air hood is provided with a dustproof grille.

[0010] Optionally, the blower is located inside the blower box; the blower box has several ventilation openings.

[0011] Optionally, the blower outlet is provided with a tee fitting, which is connected to the blower and the two air supply channels respectively.

[0012] Optionally, the air supply channel is a pipeline structure.

[0013] Optionally, the smoke chamber is recessed into the interior of the machine body; the movable panel can be horizontally installed over the smoke chamber.

[0014] The beneficial effects of this utility model are as follows: the three-sided shielding structure of the double air curtain and the flip-up movable panel can effectively block the escape path of oil fumes in the smoke chamber. Combined with the three-dimensional airtight sealing area formed by the air curtain, oil fumes are difficult to escape from the range of the smoke chamber, effectively ensuring the oil fume adsorption performance of the top-mounted range hood. Furthermore, since oil fumes are difficult to escape, the movable panel and the lower side of the casing form a flat surface when closed, which can be flush with the lower side of the upper cabinet without leakage, improving the overall visual effect of the top-mounted range hood.

[0026] Example

[0027] Reference Figures 1 to 3 The present invention proposes a top-mounted range hood with a smoke-curtain structure, comprising: a casing 10, a fan cabinet 20, a fan assembly, a movable panel 40, a flip assembly 50, and a smoke-curtain assembly 60.

[0028] The fan assembly is installed in the air handling unit 20; the air handling unit 20 is located above the casing 10; the casing 10 is provided with an oil fume adsorption chamber 11 and a smoke trapping chamber 12; an air inlet 30 is provided between the oil fume adsorption chamber 11 and the smoke trapping chamber 12; a movable panel 40 is provided below the smoke trapping chamber 12; the flipping assembly 50 can flip the movable panel 40 relative to the front side of the casing 10 to cover or open the smoke trapping chamber 12.

[0029] The air curtain assembly 60 includes a blower 61, an air supply duct 62, and an air outlet hood 63. Two air outlet hoods 63 are provided and arranged in a long strip on opposite sides of the smoke enclosure. The air outlet of the air outlet hood 63 faces downward. The blower 61 can blow air through the air supply duct 62 towards the air outlet of the air outlet hood 63 to form an air curtain on opposite sides of the movable panel 40.

[0030] In this invention, the three-sided shielding structure of the double air curtain and the rotating movable panel 40 effectively blocks the escape path of the smoke chamber 12. Combined with the three-dimensional airtight sealing area formed by the air curtain, the smoke is difficult to escape from the range of the smoke chamber 12, effectively ensuring the smoke adsorption performance of the top-mounted range hood. Furthermore, since the smoke is difficult to escape, the movable panel 40 and the lower side of the casing 10 form a flat surface when closed, which can be flush with the lower side of the upper cabinet without leakage, improving the overall visual effect of the top-mounted range hood.

[0031] In this embodiment, the cross-section of the air outlet hood 63 is a tower-shaped structure that expands from top to bottom. With this tower-shaped cross-section, the airflow delivered by the blower 61 can be guided and diffused downwards to form a wide and stable air curtain.

[0032] Furthermore, in order to protect the exhaust hood 63 and prevent dust or particles from the bottom of the range hood from entering the exhaust hood 63, a dustproof grille 64 is provided at the air outlet of the exhaust hood 63.

[0033] In this embodiment, in order to protect the blower 61 and prevent dust or particles above the air handling unit 20 from entering the blower 61, the blower 61 is installed inside the air handling box 65; the air handling box 65 has several ventilation openings.

[0034] In this embodiment, the outlet of the blower 61 is provided with a T-shaped pipe fitting 66, which connects the blower 61 and two air supply channels 62 respectively. Through the T-shaped pipe fitting 66, it is convenient to simultaneously supply air to the two air outlet hoods 63 through one blower 61.

[0035] In this embodiment, in order to facilitate the arrangement of air supply channels 62 in the air handling unit 20 and the chassis 10, the air supply channels 62 are pipe structures such as flexible hoses that are easy to wind and connect.

[0036] In this embodiment, to improve the smoke-collecting effect of the smoke-collecting chamber 12, the smoke-collecting chamber 12 is recessed into the interior of the machine body. Furthermore, the movable panel 40 can be horizontally installed over the smoke-collecting chamber 12. When the movable panel 40 is closed over the smoke-collecting chamber 12, it can be flush with the lower surface of the cabinet.

[0037] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
