[0039] The following combination Figures 1 to 5 , describing embodiments of the present invention.

[0040] like Figures 1 to 4 As shown, according to an embodiment of the present invention, a range hood is disclosed, comprising a volute assembly 1 and a casing 2, wherein the volute assembly 1 is fixed to a wall, the casing 2 is covered on the volute assembly 1, a gap is provided between the inner wall of the casing 2 and the outer surface of the volute assembly 1, the casing 2 is fixed to the wall, and a side of the casing 2 facing the wall has an opening, and the volute assembly 1 is fixed to the wall through the opening.

[0041] The range hood of the present application is configured such that the volute assembly 1 and the casing 2 are independently fixedly mounted on the wall, and a gap is provided between the inner wall of the casing 2 and the outer surface of the volute assembly 1. When smoking, the vibration generated by the operation of the fan in the volute assembly 1 is directly transmitted to the wall, and is not transmitted to the casing 2 to cause vibration of the casing 2, thereby avoiding resonance between the volute assembly 1 and the casing 2, generating large vibrations and abnormal noises, and effectively reducing vibrations and noises.

[0042] In this embodiment, the volute assembly 1 includes a volute and a fan, wherein the fan is disposed within the volute. The fan generates negative pressure when in operation, drawing cooking fumes into the volute assembly 1 and out of the housing 2. The fan also generates vibrations that are transmitted to the volute, causing the volute to vibrate synchronously.

[0043] This application does not limit the shape of the housing 2. In this embodiment, the housing 2 is a square shell, and the side of the square shell facing the wall is open, and the open side is an opening. Of course, the side of the housing 2 facing the wall can also be set as a closed surface, and an opening can be provided on the closed surface.

[0044] like Figure 1 、 Figure 5 As shown, further, the smoke inlet 11 of the volute assembly 1 is located on the side, the smoke outlet 12 of the volute assembly 1 is located at the top, and a smoke exhaust port 22 is provided on the top of the casing 2. The smoke exhaust port 22 corresponds to the smoke outlet 12 of the volute assembly 1, so that the oil smoke discharged from the volute assembly 1 flows upward through the smoke outlet 12 to the smoke exhaust port 22 and is discharged from the casing 2.

[0045] Specifically, the shape and size of the smoke exhaust port 22 match those of the smoke outlet 12 of the volute assembly 1 , so that as much oil smoke as possible from the volute assembly 1 flows into the smoke exhaust port 22 .

[0046] It should be noted that the oil smoke is sucked into the smoke inlet 11 of the volute assembly 1 through the gap between the volute assembly 1 and the casing 2 .

[0048] The mounting portion 3 is provided, and the mounting portion 3 is fixedly connected to the volute assembly 1. At the same time, the mounting portion 3 is fixed to the wall through the opening of the casing 2, thereby fixing the volute assembly 1 to the wall.

[0049] like Figure 3 As shown, in some embodiments, the mounting portion 3 is connected to the spiral surface of the volute assembly 1 , and the mounting portion 3 extends along a tangential direction of the spiral surface of the volute assembly 1 .

[0050] By arranging the spiral surface connection between the mounting portion 3 and the volute assembly 1, it is possible to avoid the mounting portion 3 causing obstruction to the smoking of the volute assembly 1, so that the oil smoke can be more smoothly inhaled into the volute assembly 1.

[0051] In this embodiment, the mounting portion 3 is a mounting plate extending along the tangential direction of the spiral surface of the volute assembly 1 , and the mounting plate is conveniently connected to a flat wall.

[0052] In some embodiments, the range hood further includes a first bracket, the first bracket and the volute assembly 1 are integrally formed, and the first bracket and the mounting portion 3 are fixedly connected.

[0053] Since the volute assembly 1 is irregular as a whole and is not convenient to connect with the mounting portion 3 , the volute assembly 1 and the first bracket are integrally formed so that the first bracket can be more conveniently connected with the mounting portion 3 .

[0054] In this embodiment, the first bracket is a flat plate to increase the mating area with the mounting plate and improve the connection strength. However, this is not limiting. For example, in other embodiments, the first bracket can also be a connecting column extending away from the volute assembly 1, and fixedly connected to the mounting portion 3 via the connecting column.

[0055] like Figure 3 As shown, in this embodiment, a plurality of first holes 32 are provided on the circumferential edge of the mounting portion 3 , and the mounting portion 3 is fixedly connected to the wall through the plurality of first holes 32 .

[0063] Furthermore, at least two hanging structures are arranged at intervals along the width direction of the mounting portion 3 .

[0064] At least two mounting portions 3 spaced apart along the width direction of the mounting portion 3 can improve the stability of the connection between the mounting portion 3 and the wall and enhance the connection strength.

[0065] There is no specific limit on the number of hanging structures. For example, two or three hanging structures are arranged at intervals along the width direction of the mounting portion 3 .

[0066] In some embodiments, the range hood further includes a shock-absorbing structure disposed inside the housing 2 , and the shock-absorbing structure is disposed between the volute assembly 1 and the wall.

[0067] A shock-absorbing structure is further provided between the volute assembly 1 and the wall. The shock-absorbing structure can absorb the vibration generated by the operation of the volute assembly 1, reduce vibration noise, and at the same time avoid the situation where the mounting part 3 becomes loose due to excessive vibration relative to the wall.

[0068] In this embodiment, a shock-absorbing structure is arranged between the mounting portion 3 and the wall to absorb the vibration of the mounting portion 3, reduce the vibration, avoid the mounting portion 3 from vibrating and loosening from the wall, and ensure the reliability of the connection between the mounting portion 3 and the wall.

[0069] Specifically, the shock absorbing structure can be provided on the side of the mounting portion 3 facing the wall and installed on the wall together with the mounting portion 3. However, the present invention is not limited thereto. For example, the shock absorbing structure can also be pre-set on the wall, and the mounting portion 3 abuts against the shock absorbing structure when installed on the wall.

[0070] Specifically, the shock-absorbing structure may be a flexible structure such as sponge, foam, rubber, etc., which is not limited in this embodiment.

[0071] like Figure 4 As shown, in some embodiments, the casing 2 extends in a direction away from the volute assembly 1 to form a flange 21, and the flange 21 is connected to the wall.

[0072] The flange 21 facilitates the connection between the housing 2 and the wall without affecting the outer structure of the housing 2 .

[0073] In some embodiments, two flanges 21 are provided and are arranged on both sides of the opening of the casing 2 . A plurality of second holes 211 are arranged at intervals along the length direction of the flange 21 . The flange 21 is fixedly connected to the wall through the plurality of second holes 211 .

[0074] In this embodiment, two flanges 21 are provided, which are arranged on both sides of the opening of the casing 2 to improve the installation stability of the casing 2. A plurality of second holes 211 are arranged at intervals along the length direction of the flange 21. The flange 21 can be fixedly connected to the wall through the plurality of second holes 211 to ensure a stable structural connection.

[0075] Specifically, the two flanges 21 can be arranged along the left and right sides of the opening, or along the upper and lower sides of the opening. In this embodiment, the two flanges 21 are arranged along the left and right sides of the opening as an example for description.

[0076] Of course, as an alternative embodiment, four flanges 21 can also be provided, distributed along the upper and lower sides and the left and right sides of the opening of the housing 2 respectively.
