Description

Technical Field

[0001] This utility model belongs to the field of range hood technology, and in particular relates to a range hood with an adjustable smoke inlet. Background Technology

[0002] A range hood is a kitchen appliance that purifies the kitchen environment. It can quickly remove the fumes produced during cooking and exhaust them outdoors. At the same time, it condenses and collects the fumes, reducing pollution, purifying the air, and providing safety features such as protection against poisoning and explosion.

[0003] When using existing dual-inlet range hoods, both inlets are open. However, the amount of oil fumes generated in the stir-fry mode is relatively large. Due to the dispersed suction, the upper inlet has insufficient suction power and cannot absorb the rising oil fumes in time, causing the oil fumes to escape and spread, which affects the user experience.

[0004] Existing patent document (publication number: CN218154390U) discloses "a dual-inlet easy-to-clean range hood", which also has the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a range hood with an adjustable smoke inlet. It has a novel structure and can adaptively adjust the smoke inlet according to the smoke situation, thereby effectively absorbing the smoke.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An adjustable smoke inlet range hood includes: a fan frame with a fan housed within it; and a smoke collection hood connected to the fan frame, the smoke collection hood having a smoke inlet communicating with a smoke inlet chamber. The smoke inlet comprises an upper smoke inlet and a lower smoke inlet, and the smoke inlet chamber comprises a first smoke inlet chamber and a second smoke inlet chamber. The upper smoke inlet communicates with the first smoke inlet chamber, and the lower smoke inlet communicates with the second smoke inlet chamber. A drive mechanism and a baffle are provided within the smoke inlet chamber, the output end of the drive mechanism being connected to the baffle. The drive mechanism rotates the baffle to a closed position, separating the first and second smoke inlet chambers. The drive mechanism also rotates the baffle to an open position, connecting the first and second smoke inlet chambers. This range hood has a novel structure and can adaptively adjust the smoke inlet according to the amount of smoke, thereby effectively absorbing smoke.

[0008] Furthermore, the smoke hood is recessed upwards to form a smoke-gathering chamber, with the upper smoke inlet located at the top of the smoke-gathering chamber. The smoke-gathering chamber can gather the oil fumes, reduce the escape of oil fumes to the surroundings, and facilitate the absorption of oil fumes.

[0009] Furthermore, an inclined smoke guide plate is provided inside the lower smoke inlet, which effectively guides the oil fumes into the second smoke inlet chamber, resulting in good smoke guiding effect.

[0010] Furthermore, an arc-shaped transition section is provided between the inclined smoke guide plate and the back plate of the smoke collection hood, which makes the smoke guiding smoother and avoids the increase in flow resistance of oil fumes due to excessive turning angle.

[0011] Furthermore, the back panel of the smoke hood is provided with an arched section, which supports the arc-shaped transition section, prevents the arc-shaped transition section from deforming, and improves its structural stability.

[0012] Furthermore, a bending plate is connected to the output end of the drive mechanism, and the bending plate is connected to a baffle. The bending plate serves as a transition connection, making it adaptable to compact installation spaces and highly versatile.

[0013] Furthermore, an LED light is installed on the inner top of the smoke hood, which increases the lighting function and makes it easier for users to clean.

[0014] Furthermore, an oil cup is connected to the bottom of the smoke collection hood. The oil cup has a front baffle, which increases the oil-blocking height of the oil cup and prevents oil droplets flowing down from the surface of the inclined smoke guide plate from falling outside the oil cup.

[0015] Furthermore, the drive mechanism adopts an electric push rod, which is characterized by its small size, high precision, and good self-locking performance. It is directly driven by a motor and does not require a pipeline air source or oil circuit.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] In non-stir-fry mode, activating the electric push rod causes the baffle to rotate downwards to the open position, connecting the first and second smoke inlets. Some fumes enter the first smoke inlet through the upper inlet, while the rest enter the second through the lower inlet, achieving simultaneous top and side suction. In stir-fry mode, which produces more fumes, activating the electric push rod causes the baffle to rotate upwards to the closed position, sealing the first smoke inlet. This isolates the first and second smoke inlets, increasing the suction of the upper inlet and effectively drawing the rising fumes into the first smoke inlet, preventing them from escaping. The inlet can be adjusted according to the amount of fumes to effectively absorb smoke. Attached Figure Description

Detailed Implementation

[0024] like Figure 1 and Figure 2 As shown, this utility model discloses a range hood with an adjustable smoke inlet, comprising: a fan frame 1 and a smoke collection hood 2. The smoke collection hood 2 is connected to the fan frame 1. A fan 17 is provided inside the fan frame 1. The smoke collection hood 2 is provided with a smoke inlet, which includes an upper smoke inlet 3 and a lower smoke inlet 4. The smoke inlet chamber inside the smoke collection hood 2 includes a first smoke inlet chamber 5 and a second smoke inlet chamber 6. The upper smoke inlet 3 is connected to the first smoke inlet chamber 5, and the lower smoke inlet 4 is connected to the second smoke inlet chamber 6.

[0025] A drive mechanism is fixed inside the first smoke inlet chamber 5. The drive mechanism uses an electric push rod 7, which is characterized by its small size, high precision, and good self-locking performance. It is directly driven by a motor and does not require a gas source or oil circuit. A baffle 8 is rotatably connected inside the second smoke inlet chamber 6 via a rotating shaft. A bending plate 9 is rotatably connected to the output end of the electric push rod 7. The bending plate 9 is fixedly connected to the baffle 8 and serves as a transition connection, which can adapt to compact installation spaces and thus effectively absorb smoke.

[0026] like Figure 3 and Figure 4 As shown, in non-stir-fry mode, the electric push rod 7 is turned on, which drives the baffle 8 to rotate downward to the open position, connecting the first smoke inlet chamber 5 and the second smoke inlet chamber 6. Some of the oil fumes enter the first smoke inlet chamber 5 through the upper smoke inlet 3, and the other part of the oil fumes enters the second smoke inlet chamber 6 through the lower smoke inlet 4, achieving the purpose of dual suction from top and side. In stir-fry mode, more oil fumes are generated. The electric push rod 7 is turned on, which drives the baffle 8 to rotate upward to the closed position, sealing the first smoke inlet chamber 5. At this time, the first smoke inlet chamber 5 and the second smoke inlet chamber 6 are separated, and the suction force of the upper smoke inlet 3 increases, effectively drawing the rising oil fumes into the first smoke inlet chamber 5 and preventing the oil fumes from escaping to the surroundings. The smoke inlet can be adjusted adaptively according to the oil fume situation, making it highly adaptable.

[0027] The smoke collection hood 2 is recessed upward to form a smoke collection chamber 10. The upper smoke inlet 3 is located at the top of the smoke collection chamber 10. The smoke collection chamber 10 can gather the oil fumes, reduce the escape of oil fumes to the surroundings, and facilitate the absorption of oil fumes.

[0028] An inclined smoke guide plate 11 is provided inside the lower smoke inlet 4. The inclined smoke guide plate 11 effectively guides the oil fumes to the second smoke inlet chamber 6, resulting in good smoke guiding effect.

[0029] An arc-shaped transition section 12 is provided between the inclined smoke guide plate 11 and the back plate of the smoke collection hood 2, which makes the smoke guiding smoother and avoids the increase in flow resistance of oil fumes due to excessive turning angle. An arched section 13 is provided on the back plate of the smoke collection hood 2, which supports the arc-shaped transition section 12, prevents the arc-shaped transition section 12 from deforming, and improves its structural stability.

[0030] The top inner part of the smoke hood 2 is equipped with an LED light 14, which increases the lighting function and makes it easier for users to clean.

[0031] The bottom of the smoke hood 2 is fitted with an oil cup 15, which is easy to install and remove and easy to clean. The oil cup 15 is provided with a front baffle 16, which increases the oil blocking height of the oil cup 15 and prevents oil droplets flowing down from the surface of the inclined smoke guide plate 11 from falling outside the oil cup 15.

[0032] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
