Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] Range hoods are essential kitchen appliances, and side-draft range hoods are particularly popular due to their lower smoke inlet and slimmer profile. To achieve better smoke extraction, baffles are typically installed to block rising fumes, thus achieving smoke containment. However, due to the limitations of the range hood's design, the baffles of most side-draft range hoods have a limited opening angle and cannot be adjusted according to the concentration of fumes produced during cooking. While some range hoods do offer adjustable baffle angles, their complex structures result in lower stability.

[0003] Therefore, there is an urgent need for a range hood to solve the above problems. Utility Model Content

[0004] This utility model aims to at least partially solve one of the problems existing in the prior art. To this end, this utility model proposes a range hood that, by setting an upper flip-up structure and a lower flip-up structure, allows the smoke inlet of the smoke collection hood to have three opening degrees, making it suitable for different cooking scenarios. The structure is simple and compact.

[0005] The above objectives are achieved through the following technical solutions:

[0006] A range hood, comprising:

[0007] A smoke collection hood, which has a smoke collection chamber with a smoke inlet facing forward;

[0008] A flap assembly includes an upper flap structure and a lower flap structure. The upper flap structure includes an upper flap body and an upper flap drive structure. The lower flap structure includes a lower flap body and a lower flap drive structure. The lower flap body is disposed below the upper flap body and movably connected to the upper flap body. The upper flap drive structure can drive the upper flap body to swing relative to the smoke collection hood between a first position and a second position. When the upper flap body is in the first position, it can close the upper part of the smoke inlet. When the lower flap body is in the second position, it can close the upper part of the smoke inlet. When the upper flap body is in the second position, the upper flap body can open the upper part of the smoke inlet. The lower flap driving structure can drive the lower flap body to swing relative to the smoke collection hood between the third and fourth positions. When the lower flap body is in the third position, the lower flap body and the upper flap body are coplanar. When the lower flap body is in the fourth position, the lower end of the lower flap body swings away from the smoke inlet and forms an angle β with the upper flap body, where 0° < β < 180°.

[0009] Optionally, the upper flap drive structure includes a first mounting base, an upper flap drive component, and an upper flap transmission rod assembly. The upper flap drive component is mounted in the smoke collection chamber through the first mounting base. One end of the upper flap transmission rod assembly is connected to the output end of the upper flap drive component, and the other end of the upper flap drive rod assembly is connected to the upper flap body.

[0010] Optionally, the upper flap transmission rod assembly includes:

The upper flap drive can drive the first transmission rod to swing between a fifth position and a sixth position. When the first transmission rod is in the fifth position, the second end of the first transmission rod is in front of the first end, and the upper flap body is in the first position. When the first transmission rod is in the sixth position, the second end of the first transmission rod swings downwards to below the first end, and the upper flap body is in the second position.

[0012] The second transmission rod has its first end and second end positioned opposite each other and hinged to each other. When the first transmission rod is in the fifth position, the second end of the second transmission rod is located behind the first end of the second transmission rod. When the first transmission rod is in the sixth position, the second end of the second transmission rod swings downward to below the first end of the second transmission rod.

[0013] The third transmission rod has its first end and second end positioned opposite each other. The first end of the third transmission rod is hinged to the first mounting base, and the middle part of the third transmission rod is hinged to the second end of the second transmission rod. When the first transmission rod is in the fifth position, the second end of the third transmission rod is positioned above the first end of the third transmission rod. When the first transmission rod is in the sixth position, the second end of the third transmission rod swings forward to the front of the third transmission rod.

[0014] The fourth transmission rod has its first end and second end positioned opposite each other. The first end of the fourth transmission rod is hinged to the second end of the third transmission rod, and the second end is hinged to the upper flap body.

[0039] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0040] Please refer to Figures 1-11This utility model provides a range hood, including a smoke collection hood 1 and a flap assembly 2. The smoke collection hood 1 has a smoke collection chamber 100 with the smoke inlet facing forward. The flap assembly 2 includes an upper flap structure 22 and a lower flap structure 21. The upper flap structure 22 includes an upper flap body 221 and an upper flap drive structure 222. The lower flap structure 21 includes a lower flap body 211 and a lower flap drive structure 212. The lower flap body 211 is disposed below the upper flap body 221 and movably connected to it. The upper flap drive structure 222 can drive the upper flap body 221 to swing relative to the smoke collection hood 1 between a first position and a second position. When the upper flap body 221 is in the first position, it can close. At the upper part of the smoke inlet, when the upper flap body 221 is in the second position, the upper flap body 221 can open the upper part of the smoke inlet. The lower flap drive structure 212 can drive the lower flap body 211 to swing relative to the smoke collection hood 1 between the third and fourth positions. When the lower flap body 211 is in the third position, the lower flap body 211 and the upper flap body 221 are coplanar. When the lower flap body 211 is in the fourth position, the lower end of the lower flap body 211 swings away from the smoke inlet and forms an angle β with the upper flap body 221, 0° < β < 180°. Specifically, when the upper flap body 221 is in the first position and the lower flap body 211 is in the third position, the entire air inlet is closed by the flap assembly 2; such as Figures 1-3 As shown, when the upper flap body 221 is in the first position and the lower flap body 211 is in the fourth position, the upper flap body 221 closes the upper part of the smoke inlet, and the lower flap structure 21 opens the lower part of the smoke inlet. The entire air inlet is opened to the first opening degree by the flap assembly 2, which is suitable for situations with a small amount of oil smoke; Figures 6-8 As shown, when the upper flap body 221 is in the second position and the lower flap body 211 is in the third position, the entire air inlet is opened to the second opening degree by the flap assembly 2. This is suitable for situations with a large amount of oil fumes. Figure 10 and 11 As shown, when the upper flap body 221 is in the second position and the lower flap body 211 is in the fourth position, the entire air inlet is opened to the third opening degree by the flap assembly 2. This is suitable for situations with a large amount of oil fumes (such as stir-frying).

[0041] This utility model, by setting up an upper flip-up structure 22 and a lower flip-up structure 21, enables the smoke inlet of the smoke collection hood 1 to have three opening degrees, which is suitable for different cooking scenarios, and the structure is simple and compact.

[0042] Optionally, in this embodiment, β is 105°, so that when the air inlet is opened to the third degree, the lower flap body 211 can be flipped upward, thereby reducing the occupation of the cooking position below, while also increasing the opening of the air inlet.
