[0022] The present application will be further described in detail below with reference to the accompanying drawings.

[0023] This application discloses an air intake system, referring to... Figure 1The system includes a fan 1, an air box 2, and a flow guiding unit 3. The fan 1 is located inside the air box 2 and has an intake port 101 for drawing in airflow and an outlet port 102 for discharging the drawn-in airflow outside the air box 2. The side of the fan 1 with the intake port 101 is an air inlet surface 11, and the flow guiding unit 3 is located on one side of the air inlet surface 11. The air box 2 has a main inlet 301 and a secondary inlet 302 formed within it via the flow guiding unit 3. Figure 4 The main inlet 301 is used to guide most of the airflow to the inlet 101 along the first direction, and the secondary inlet 302 is used to guide the other part of the airflow to the inlet 101 along the second direction which is set at an angle to the first direction.

[0024] Reference Figure 1 and Figure 4 When this embodiment is applied to an integrated stove, the fan 1 is located below the stove's main unit, and the inlet connecting the air box 2 and the main unit is located above the fan 1's intake 101. The main inlet 301 guides most of the airflow entering the air box 2 in a vertically downward first direction. Another portion of the airflow is guided from the secondary inlets 302 on either side of the main inlet 301 along a second direction to the intake 101. In this embodiment, the first direction is not merely a vertical straight line; due to the action of the fan 1, some airflow outside the main inlet 301 also bends and enters the intake 101 from the main inlet 301. The first direction includes multiple directions of airflow from top to bottom. Similarly, the second direction is not only the horizontal direction from the side of the guide unit 3 through the secondary inlet 302 into the inlet 101. Under the action of the fan 1, some airflow will turn and enter the inlet through the guide effect of the secondary inlet 302 during the flow from top to bottom. The second direction includes multiple directions of horizontal flow from the outside of the guide unit 3 to the side of the inlet 101. The angle between the first direction and the second direction allows the airflow to enter the inlet 101 from multiple directions through the guide unit 3, thus improving the intake efficiency of the airflow.

[0025] The projection of the main inlet 301 from top to bottom is rectangular. In other embodiments, the main inlet 301 may be circular, elliptical, or other irregular shapes. The projection of the secondary inlet 302 along the second direction is also rectangular. In other embodiments, the secondary inlet 302 may be circular, elliptical, or other irregular shapes.

[0026] Reference Figure 1 and Figure 2 In this embodiment, the flow guiding unit 3 includes a main component 31 and a secondary component 32.

[0027] The main component 31 is plate-shaped and is distributed opposite to the air inlet surface 11. Under the projection perpendicular to the air inlet surface 11, the projection of the main component 31 covers the entire intake port 101. In other embodiments, under the projection perpendicular to the air inlet surface 11, the projection of the main component 31 covers a portion of the intake port 101, and the projection of the main component 31 covers the lowest point of the intake port 101.

[0028] In this embodiment, the main component 31 has a straight edge 310 extending along a second direction at the main inlet 301, and an arc-shaped edge 311. The arc-shaped edge 311 is located below the straight edge 310, and its two ends are respectively connected to the two ends of the straight edge 310. Under the projection perpendicular to the air inlet surface 11, the projection of the main component 31 is approximately semi-circular. In other embodiments, the projection of the main component 31 can be a square plate-like structure.

[0029] The secondary component 32 is vertically connected to the edge of the main component 31 facing the air inlet surface 11. The secondary component 32 extends along the arc edge 311 and forms a U-shape under the projection perpendicular to the air inlet surface 11. The secondary component 32 is located between the main component 31 and the air inlet surface 11, and both ends of the secondary component 32 extend close to the straight edge 310. When the air guide unit 3 is installed in the air box 2, the side of the secondary component 32 facing away from the main component 31 approaches or abuts the air inlet surface 11.

[0030] A secondary inlet 302 is provided on both sides of the main inlet 301 along the second direction in the secondary component 32. In other embodiments, multiple secondary inlets 302 may also be provided. The secondary inlets 302 extend only in the first direction, so that there is no inlet at the arc-shaped bottom position of the secondary component 32, thus avoiding ineffective air intake at the bottom.

[0031] The arc-shaped bottom of the secondary component 32 is provided with an oil leakage hole 4, and the main inlet 301 is located directly above the oil leakage hole 4, so that the condensed oil fumes can flow out from the oil leakage hole 4.

[0032] The combination of the air guide unit 3 and the air inlet surface 11 forms the main inlet 301. Combined with the arc shape of the secondary component 32 and the secondary inlet 302, most of the airflow drawn in from the head enters the suction port 101 from the main inlet 301 from top to bottom, and a portion of the airflow enters the suction port 101 from the secondary inlet 302 laterally, which greatly improves the air intake efficiency and makes the air intake evenly distributed. When applied to the integrated stove, it makes the pots and pans of the two burners on the left and right sides of the integrated stove have the same uniform air intake.

[0033] To facilitate the fixing of the airflow guiding unit 3, each end of the secondary component 32 is integrally formed with a mounting portion 8. The two mounting portions 8 extend towards opposite sides and generally along the second direction, allowing the airflow guiding unit 3 to be fixed to the inner wall of the wind box 2 using fasteners. In other embodiments, the mounting portions 8 can also be formed separately from the secondary component 32 and then fixed, or the mounting portions 8 can be formed on the main component 31. In this embodiment, the mounting portions 8 can guide part of the airflow on both sides to the main inlet 301.

[0034] Reference Figure 2 and Figure 3 In order to enable the main component 31 to also have a noise reduction effect, the straight edge 310 of the main component 31 is provided with an arc-shaped part 5 extending away from the air inlet surface 11, which reduces the turbulence noise of the internal airflow field.

[0035] The main component 31 is provided with an array of multiple sound-absorbing holes 6.

[0036] The main component 31 also has an arc-shaped part 5 extending away from the air inlet surface 11 on the arc edge 311. The arc-shaped part 5 forms a placement cavity 70 on the side of the main component 31 away from the air inlet surface 11. The placement cavity 70 is provided with a sound-absorbing material 7, such as sound-absorbing cotton.

[0037] The air box 2 has a rear plate 21 located on the side of the sound-absorbing material 7 facing away from the air inlet surface 11. The sound-absorbing material 7 is located between the rear plate 21 and the main component 31, forming a sound-absorbing module, thereby significantly reducing the noise of the fan 1 from the source of noise radiation. The rear plate 21 is also the rear plate 21 of the integrated stove frame.

[0038] This application also discloses an integrated stove, including an air intake system described in the above technical solution.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
