[0002] With the improvement of life quality and the increasing importance of kitchen aesthetics, users' requirements for kitchen appliances are no longer limited to functionality, but pay more attention to the aesthetics of the product, space utilization, and coordination with the overall home style. It is in this context that fully concealed range hoods came into being, meeting users' needs for a clean, beautiful, and practical kitchen space.

[0003] Based on this demand, the industry's design for concealed range hoods adopts an overall lifting method to hide the entire range hood in the cabinet. This form has higher performance requirements on the power structure, greater energy consumption, and higher requirements on the installation environment, making it difficult to popularize it.

[0045] Embodiment 1

[0046] Please refer to Figure 1-Figure 7The present invention provides a range hood, comprising a smoke collecting hood 2, a front smoke baffle structure 3 and a side smoke baffle structure 4. A smoke collecting cavity with a smoke inlet at the lower side is provided in the smoke collecting hood 2. One end of the front smoke baffle structure 3 is movably connected to the front end of the smoke collecting hood 2 for opening and closing the smoke inlet. The side smoke shield structure 4 includes a mounting assembly, a rotating shaft assembly and a first side wing plate 41. The mounting assembly is installed in the smoke collecting chamber.

The first side wing plate 41 is installed on the left and / or right side of the smoke collecting hood 2 and is located on the rear side of the front smoke shield structure 3. When the front smoke shield structure 3 opens the smoke inlet, the first side wing plate 41 extends downward from the smoke collecting chamber under the action of gravity. When the front smoke shield structure 3 closes the smoke inlet, the front smoke shield structure 3 pushes the first side wing plate 41 to rotate relative to the mounting assembly and retract it into the smoke collecting chamber. In this way, on the one hand, when the front smoke shield structure 3 opens the smoke inlet, the first side wing plate 41 can also extend out of the smoke collecting chamber under the action of gravity to achieve the collection of smoke, without the need for power to push the first side wing plate 41 to unfold. On the other hand, when the front smoke baffle structure 3 closes the smoke inlet, the front smoke baffle structure 3 can push the first side wing panel 41 into the smoke collecting chamber, so as to store the first side wing panel 41 in the smoke collecting chamber, thereby achieving a better hiding effect and making the appearance of the range hood more beautiful when in standby mode.

When the front smoke baffle structure 3 closes the smoke inlet, the front smoke baffle structure 3 pushes the first side wing plate 41 to swing upward relative to the mounting assembly through the first shaft 431 and the second shaft 432 into the smoke collecting chamber.

[0048] Optionally, the first rotating shaft 431 and the second rotating shaft 432 are spaced apart in the front-to-back direction, so that the first side wing plate 41 can swing in the front-to-back direction relative to the mounting assembly.

[0049] Optionally, the mounting assembly includes a fixing member 45, a connecting rod 44 and a mounting plate 42, the fixing member 45 is installed in the smoke collecting chamber, the middle part of the connecting rod 44 is installed on the fixing member 45 and can rotate relative to the fixing member 45, the left end and / or the right end of the connecting rod 44 passes through the mounting plate 42 and is connected to the first end of the first rotating shaft 431, and the first end of the second rotating shaft 432 is rotatably connected to the mounting plate 42. By setting the connecting rod 44, when the first side wing plates 41 are set at the left and right ends of the smoke collecting hood 2, the two first side wing plates 41 can swing synchronously, and the installation of the two first side wing plates 41 is facilitated.

[0050] Optionally, the first side wing plate 41 is located outside the mounting plate 42 to facilitate assembly between the mounting assembly and the first side wing plate 41 .

[0051] Optionally, the width of the first side wing panel 41 gradually decreases from front to back. When the front smoke baffle structure 3 opens the smoke inlet, the first side wing panel 41 is tilted downward from back to front to facilitate the storage and deployment of the first side wing panel 41.

[0052] Optionally, when the front smoke baffle structure 3 closes the smoke inlet, the front end of the front smoke baffle structure 3 is hinged to the front end of the smoke hood 2, and when the front smoke baffle structure 3 opens the smoke inlet, the upper end of the front smoke baffle structure 3 is hinged to the front end of the smoke hood 2. To facilitate the swing of the front smoke baffle structure 3, when the front smoke baffle structure 3 opens the smoke inlet, the front smoke baffle structure 3 can enclose the wall of the kitchen and the first side wing plate 41 to form a smoke collecting cavity, and at the same time, it is convenient for the front smoke baffle structure 3 to push the first side wing plate 41 into the smoke collecting cavity.

[0053] Optionally, when the front smoke baffle structure 3 opens the smoke inlet, an angle θ is formed between the front smoke baffle structure 3 and the smoke collecting hood 2 , and 90°<θ<180°.
