Please refer to FIG. 1 to FIG. 6, the air intake structure 10 of the embodiment of the present application is used for a combined cooking device 1000. The combined cooking device 1000 includes a panel 300, a cooking appliance (not shown), and a hood 100. The cooking appliance and the hood 100 are installed on the panel 300, and the hood 100 is located below the panel 300. The hood 100 includes a fan unit 20 and an air intake structure 10, and the fan unit 20 is connected to the air intake structure 10. The panel 300 is provided with a through hole 310, and the air intake structure 10 is arranged at the through hole 310 so as to be able to be raised and lowered.

In this way, the oil fume generated during the cooking process can enter the fan unit 20 through the air intake structure 10, and then be exhausted to the outdoors. It can be understood that on a stove where the hood 100 cannot be installed, the inability to discharge the oil smoke in time will affect the indoor environment. The combined cooking device 1000 with heating function and smoke exhaust function can effectively reduce indoor oily smoke, avoid indoor environmental pollution, benefit the health of the user, and expand the use environment of the combined cooking device 1000.

Specifically, referring to FIG. 3, the fan unit 20 includes a volute 22, a motor 24 and an impeller 26, and the motor 24 and the impeller 26 are located in the volute 22. The hood 100 includes an air inlet structure 10 and a connecting channel 30, and the air inlet structure 10 is connected to the air inlet of the volute 22 through the connecting channel 30. The smoke machine 100 further includes a smoke pipe 40 connected to the air outlet of the volute 22. The air intake structure 10 can be raised and lowered at the through hole 310 of the panel 300, that is, the position of the air intake structure 10 can be adjusted. The air intake structure 10 includes a first position and a second position. It can be understood that when the user uses the combined cooking device 1000 and needs to exhaust smoke, the air intake structure 10 is in the first position, and the air intake structure 10 can rise a certain height higher than the panel 300 to achieve the effect of collecting smoke; when there is no need to exhaust smoke, The air intake structure 10 is in the second position, and the air intake structure 10 can be lowered to the same plane as the panel 300 to reduce the occupied space of the combined cooking device 1000 and improve the aesthetics of the combined cooking device 1000 and the comfort of users. When the air intake structure 10 is in the second position, the air intake structure 10 is sleeved with a connecting channel 30. The lifting of the air intake structure 10 can be adjusted manually or by a driving member. Preferably, the lifting of the air intake structure 10 is adjusted by a driving part, which is convenient for users to operate. It should be noted that the connecting channel 30 is fixed.

Please refer to FIG. 1 to FIG. 7, the air intake structure 10 includes an air intake net 12 and an air duct body 14. The air intake net 12 is provided with an air inlet 122 of the air intake net. A mesh structure 124 is provided in the air inlet 122 of the air intake net. The mesh structure 124 includes a plurality of circumferential ribs 1242. The plurality of circumferential ribs 1242 are ring-shaped and arranged concentrically at intervals. The circumferential rib 1242 is in an arc shape that is convex upwards toward the center of the air inlet 122 of the air inlet network (see FIG. 7 for details). The air duct body 14 is provided on the lower surface of the air intake net 12, and the air duct body 14 is a cylindrical structure with an open upper end and a lower end, and the air duct body 14 forms an air flow channel inside.

In the air intake structure 10 of the embodiment of the present application, since the plurality of circumferential ribs 1242 are arranged concentrically and the circumferential ribs 1242 are in an upwardly convex arc shape toward the center of the air inlet structure 10, the airflow enters the air inlet from the air inlet 122 of the air inlet. In the structure 10, the airflow direction of the intake air can flow from the periphery to the center, thereby making the negative pressure zone more short and wide, and improving the smoking effect of the hood 100 under the same air volume.

It can be understood that the negative pressure zone distribution of the air intake structure 10 will affect the smoke exhaust effect of the hood 100. When the negative pressure zone is more short and wide, the oil fume on the peripheral side is more likely to be sucked into the air inlet 122 of the air inlet network, thereby improving the smoking effect of the hood 100 under the same air volume. At the same time, the net-like structure 124 in the air inlet 122 of the air intake screen separates the inside and outside of the hood 100. On the one hand, it makes the hood 100 more beautiful, and on the other hand, it prevents users from contacting the internal components of the hood 100 to avoid possible existence. The risk of mechanical damage.

In addition, when the air intake structure 10 of the embodiment of the present application is applied to the combined cooking device 1000, the air duct body 14 is a structure independent of the panel 300. Therefore, the air intake structure 10 can be separately performed under relevant requirements. Repair, maintain or replace. For example, when the air intake structure 10 fails, only the air intake structure 10 can be replaced without replacing the entire panel 300, which facilitates maintenance and repairs and reduces maintenance and repair costs.

It should be noted that the circumferential rib 1242 is in an upwardly convex arc shape toward the center of the air inlet 122 of the air inlet network. At a first angle, the tangent to one end of the circumferential rib 1242 located in the air outlet direction of the air inlet 122 of the air intake net forms a second angle with the vertical direction, and the first angle is greater than the second angle.

In some embodiments, the air intake opening 122 of the air intake screen is circular, and the scan line of the circumferential rib 1242 is circular and concentric with the projection circle of the air intake opening 122 of the air intake screen.

In this way, the negative pressure area is made as uniform as possible along the center of the air inlet 122 of the air inlet network to ensure the smoking effect of the cooking appliances in different positions, and at the same time meet the aesthetic requirements. In the illustrated embodiment, the scan lines of the circumferential ribs 1242 are all circular, and the scan projection surface of the circumferential ribs 1242 is unchanged along the scan line of the circumferential ribs 1242. It can be understood that the circumferential ribs 1242 are along the horizontal direction. The cross-sections are all round. The distribution of the circumferential ribs 1242 in the radial direction is uniform and the starting points are on the same plane. In other embodiments, the circumferential ribs 1242 may be designed in other shapes, such as oval, square, rectangular, etc., and the plurality of circumferential ribs 1242 may be the same shape or include different shapes. The area and shape of the scanning projection surface along the scanning line can be variable. The distribution of the circumferential ribs 1242 in the radial direction may be non-uniform, and the starting point may not be in the same plane, and there may be a height difference. For example, a design method that ensures that the area between every two circumferential ribs 1242 is equal is adopted. It should be noted that the scanning projection surface of the circumferential rib 1242 is perpendicular to the scanning line of the circumferential rib 1242.

The scan line of the circumferential rib 1242 will be further described below. It can be understood that for a rectangle in the plane, the long side of the rectangle can be regarded as the scan line, and the short side of the rectangle can be translated from one end of the long side of the rectangle to the other end. The rectangle is formed; for a cube in space, the high side of the cube can be regarded as a scan line, and the bottom surface of the cube can be translated from one end of the high side to the other end to form the cube. The bottom surface of the cube is the scanning projection surface. Therefore, for a circumferential rib 1242, the upper edge of the circumferential rib 1242 can be regarded as a scan line, the scan line is a circle, and the circumferential rib 1242 can be cut in the vertical direction at any diameter position of the scan line to obtain an inverted shape. The eight-shaped cross section, the inverted eight-shaped cross section can be rotated 180° along the scanning line to form the circumferential rib 1242, and the inverted eight-shaped cross section is the scanning projection surface.

In another embodiment, the air intake opening 122 of the air intake screen is elliptical, and the scanning line of the circumferential rib 1242 is elliptical and concentric with the projected ellipse of the air intake opening 122 of the air intake screen. In this way, it is ensured that the negative pressure zone is symmetrical along the major axis and the minor axis of the projection ellipse of the air inlet 122 of the air inlet network, and at the same time meets the aesthetic requirements. The beneficial effects and explanations of the embodiment in which the scanning line of the circumferential rib 1242 is a circle and is concentric with the projection circle of the air inlet 122 of the air intake net are also applicable to this embodiment, and will not be repeated here.

In some embodiments, the mesh structure 124 includes a plurality of radial ribs 1244, and each radial rib 1244 is connected to a plurality of circumferential ribs 1242.

In this way, a plurality of circumferential ribs 1242 are supported and connected by the radial ribs 1244. It can be understood that the circumferential ribs 1242 are arranged along the circumference of the air inlet 122 of the air intake net, and a plurality of circumferential ribs 1242 need to be connected together. In this embodiment, a plurality of radial ribs 1244 are provided, so that each radial rib 1244 is connected to a plurality of circumferential ribs 1242, so as to ensure the stability of the mesh structure 124.

In some embodiments, the air intake opening 122 of the air intake screen is circular, and the scanning line of the radial ribs 1244 is a straight line and coincides with the radius of the projection circle of the air intake opening 122 of the air intake screen.

In this way, the circumferential ribs 1242 are supported by the radial ribs 1244, while meeting the aesthetic requirements. In the illustrated embodiment, the scan lines of the radial ribs 1244 are all straight lines, and the scan projection surface of the radial ribs 1244 remains unchanged along the scan line of the radial ribs 1244. It can be understood that the radial ribs 1244 are along the vertical direction. The cross-sections are all rectangular. The long axis of the section is parallel to the air inlet axis A, and the air inlet axis A refers to the central axis of the air inlet 122 of the air inlet network. The cross section of the radial rib 1244 is an axisymmetric figure. In other embodiments, the cross section of the radial rib 1244 may be a non-axisymmetric figure, and the area and shape of the scanning projection surface along the scanning line may be variable. It should be noted that the scanning projection plane of the radial ribs 1244 is perpendicular to the scanning line of the circumferential ribs 1242. The radial ribs 1244 can prevent the circumferential ribs 1242 from deforming, and increase the structural stability of the air inlet 122 of the air intake net.

Further, for a radial rib 1244, the upper edge of the radial rib 1244 can be regarded as a scan line. The scan line is a straight line and coincides with the radius of the projection circle of the air inlet 122 of the air inlet screen. A rectangular cross section can be obtained by intercepting the radial rib 1244 in the straight direction. The rectangular cross section is translated from one end of the scan line to the other end of the scan line to form the radial rib 1244. The rectangular cross section is the scanning projection surface.

In another embodiment, the air intake opening 122 of the air intake screen is elliptical, and the scan line of the radial ribs 1244 is a straight line and coincides with the long semi-axis or the short semi-axis of the projected ellipse of the air intake opening 122 of the air intake screen. In this way, the circumferential ribs 1242 are supported by the radial ribs 1244, while meeting the aesthetic requirements. The beneficial effects and explanations of the embodiment in which the scanning line of the radial rib 1244 is a straight line and coincides with the radius of the projected circle of the air inlet 122 of the air intake net is also applicable to this embodiment, and will not be repeated here.

8 and 9, in some embodiments, the circumferential ribs 1242 are rounded in the front direction E of the flow field; and/or the radial ribs 1244 are rounded in the front direction E of the flow field.
