Referring to fig. 1 to 4, an air intake structure 10 according to an embodiment of the present invention is used for a combined cooking apparatus 1000. The combined cooking apparatus 1000 includes a panel 300, a cooking appliance (not shown), and a machine 100 for making cigarettes. The cooking appliance and the range hood 100 are mounted to the panel 300 with the range hood 100 positioned below the panel 300. The range 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 inlet structure 10 is disposed at the through hole 310 in a lifting manner.
Therefore, oil smoke generated in the cooking process can enter the fan unit 20 through the air inlet structure 10 and then be discharged outdoors. It can be appreciated that on a cooktop where the range hood 100 cannot be installed, the lack of timely discharge of the fumes can affect the indoor environment. The combined cooking device 1000 with the heating function and the smoke exhausting function can effectively reduce indoor oil smoke, avoid indoor environmental pollution, be beneficial to the physical health of a user and enlarge the range of 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, the motor 24 and the impeller 26 being located within the volute 22. The smoke machine 100 comprises an air inlet structure 10 and a connecting channel 30, wherein the air inlet structure 10 is connected with an air inlet of the volute 22 through the connecting channel 30. The cigarette making machine 100 further comprises a cigarette tube 40, and the cigarette tube 40 is connected with the air outlet of the volute 22. The air intake structure 10 can be lifted up and down at the through hole 310 of the panel 300, that is, the position of the air intake structure 10 is adjustable. The air intake structure 10 includes a first position and a second position.

Under the condition that the air inlet structure 10 is at the second position, the air inlet structure 10 is sleeved with the connecting channel 30. The lifting of the air intake structure 10 can be adjusted by manual adjustment or by a driving member. Preferably, the lifting of the air intake structure 10 is adjusted by a driving member, which is convenient for the user to operate. It should be noted that the connecting channel 30 is stationary.
Referring to fig. 1-5, the air intake structure 10 includes an air intake screen 12 and a peripheral wall 14. The peripheral wall 14 is provided on the lower surface of the air inlet net 12. The air inlet net 12 is provided with an air inlet net air inlet 122. A net structure 124 is arranged in the air inlet 122 of the air inlet net. The mesh structure 124 includes a plurality of circumferential ribs 1242. The plurality of circumferential ribs 1242 are arranged in an annular shape and concentrically at intervals. The circumferential rib 1242 is in an arc shape protruding upward toward the center of the air inlet 122 of the air inlet net (see fig. 5 for details).
The utility model discloses embodiment's air inlet structure 10 because a plurality of circumference muscle 1242 set up with one heart and circumference muscle 1242 is to the arc that the air inlet structure 10 center is to the epirelief, when the air current gets into air inlet structure 10 from air inlet net air intake 122, can make the air current flow direction of admitting air be by flowing to the center all around like this, and then make the negative pressure zone arrange more partially short and wide, improved the smoking effect of cigarette machine 100 under the same amount of wind.
It will be appreciated that the negative pressure zone distribution of the air intake structure 10 affects the smoke evacuation performance of the cigarette maker 100. Under the condition that the arrangement of the negative pressure region is more biased to be shorter and wider, the oil smoke on the peripheral side is more easily sucked into the air inlet 122 of the air inlet net, so that the smoking effect of the range hood 100 with the same air quantity is improved. Meanwhile, the mesh structure 124 in the air inlet 122 of the air inlet net separates the interior and the exterior of the cigarette maker 100, so that the cigarette maker 100 is more attractive on one hand, and on the other hand, the user can be prevented from contacting the internal parts of the cigarette maker 100, thereby avoiding the risk of mechanical damage which may exist.
It should be noted that the circumferential rib 1242 is an arc shape protruding upward toward the center of the air inlet net air inlet 122, and it can be understood that a tangent line of one end of the circumferential rib 1242 located in the air inlet direction of the air inlet net air inlet 122 forms a first angle with the vertical direction, a tangent line of one end of the circumferential rib 1242 located in the air outlet direction of the air inlet net air inlet 122 forms a second angle with the vertical direction, and the first angle is greater than the second angle.
In some embodiments, the air inlet mesh inlets 122 are circular, and the scan lines of the circumferential ribs 1242 are circular and concentric with the projected circle of the air inlet mesh inlets 122.
Therefore, the negative pressure area is as uniform as possible along the center of the air inlet net air inlet 122, so that the smoking effect of cooking appliances at different positions is ensured, and meanwhile, the requirement of aesthetic property is met. In the illustrated embodiment, the scanning lines of the circumferential rib 1242 are all circular, and the scanning projection plane of the circumferential rib 1242 is unchanged along the scanning lines of the circumferential rib 1242, which can be understood that the cross section of the circumferential rib 1242 along the horizontal direction is all circular. The distribution of the circumferential ribs 1242 in the radial direction is uniform and the starting points are in 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 may include different shapes. The area and shape of its scan projection surface along the scan line may be variable. The distribution of the circumferential ribs 1242 in the radial direction may be non-uniform, the starting points may not be in the same plane, and there is a height difference, for example, a design method that ensures that the areas between every two circumferential ribs 1242 are equal is adopted. Note that the scan projection plane of the circumferential rib 1242 is perpendicular to the scan line of the circumferential rib 1242.
In another embodiment, the grill intake opening 122 is oval, and the scan line of the circumferential rib 1242 is oval and concentric with the projected oval of the grill intake opening 122. Therefore, the symmetry of the negative pressure area along the major axis and the minor axis of the projection ellipse of the air inlet 122 of the air inlet net is ensured, and meanwhile, the requirement of aesthetic property is met. The beneficial effects and the explanation of the above embodiment that the scanning line of the circumferential rib 1242 is a circle and is concentric with the projection circle of the air inlet net 122 are also applicable to this embodiment, and are not described herein again.
In certain embodiments, the mesh structure 124 includes a plurality of radial ribs 1244, each radial rib 1244 connecting a plurality of circumferential ribs 1242.
As such, the 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 inlet net, and a plurality of circumferential ribs 1242 need to be connected together. This embodiment makes a plurality of circumference muscle 1242 be connected to every radial muscle 1244 through setting up a plurality of radial muscle 1244 to guarantee the steadiness of network structure 124.
In some embodiments, the air inlet net inlet 122 is circular, and the scan line of the radial rib 1244 is a straight line and coincides with the radius of the projected circle of the air inlet net inlet 122.
So, support circumference muscle 1242 through radial muscle 1244, satisfy the aesthetic property requirement simultaneously. In the illustrated embodiment, the scanning lines of the radial ribs 1244 are all straight lines, and the scanning projection plane of the radial ribs 1244 is unchanged along the scanning lines of the radial ribs 1244, which can be understood that the cross sections of the radial ribs 1244 in the vertical direction are all rectangular. The long axis of the cross section is parallel to the air inlet axis a, which refers to the central axis of the air inlet 122 of the air inlet net. The cross-section of the radial ribs 1244 is in an axisymmetric pattern. In other embodiments, the cross-section of the radial rib 1244 may be a non-axisymmetric pattern, and the area and shape of the scan projection plane along the scan line may be variable. Note that the scan projection plane of the radial rib 1244 is perpendicular to the scan line of the circumferential rib 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 inlet net.
In another embodiment, the air inlet net air inlet 122 is elliptical, and the scan line of the radial rib 1244 is a straight line and coincides with the major half axis or the minor half axis of the projected ellipse of the air inlet net air inlet 122. So, support circumference muscle 1242 through radial muscle 1244, satisfy the aesthetic property requirement simultaneously. The beneficial effects and the explanation of the above embodiment that the scanning line of the radial rib 1244 is a straight line and coincides with the projection circle radius of the air inlet net 122 are also applicable to this embodiment, and are not described herein again.
Referring to fig. 6 and 7, in some embodiments, the circumferential ribs 1242 are rounded in the front end direction E of the flow field; and/or the radial ribs 1244 are rounded in the flow field front end direction E.
Therefore, the flow separation in the front end direction E of the flow field can be reduced by adapting to the change of different air quantity gears and the change of the back pressure incoming flow direction D, so that the flow resistance of oil smoke flow is reduced, and the generation of local noise is reduced. It is appreciated that the range hood 100 operates to cause the smoke to form a flow field, wherein the flow direction of the smoke is from the front end direction E of the flow field to the rear end direction F of the flow field. One end of the circumferential rib 1242 and/or the radial rib 1244 in the front end direction E of the flow field is rounded, so that the resistance of oil smoke flowing can be reduced, and the generation of local noise can be reduced. Preferably, the circumferential ribs 1242 are rounded in the flow field front end direction E, and the radial ribs 1244 are also rounded in the flow field front end direction E. Of course, in other embodiments, the circumferential ribs 1242 may be rounded in the flow field front end direction E, or the radial ribs 1244 may be rounded in the flow field front end direction E.
Referring to fig. 6 and 7, in some embodiments, the circumferential rib 1242 is chamfered in the rear end direction F of the flow field; and/or the radial ribs 1244 are chamfered in the direction F at the rear end of the flow field.
Therefore, the sectional area of the tail end can be reduced by chamfering the angle F in the rear end direction of the flow field, and the scale of falling vortex generated by fluid is reduced, so that the flowing resistance of oil smoke is reduced, and the generation of local noise is reduced. It can be understood that the end of the circumferential rib 1242 and/or the radial rib 1244 in the rear end direction F of the flow field is chamfered, so that the resistance to oil smoke flow can be reduced, and the generation of local noise can be reduced. Preferably, the circumferential ribs 1242 are chamfered in the rear end direction F of the flow field, and the radial ribs 1244 are also chamfered in the rear end direction F of the flow field. Of course, in other embodiments, the circumferential ribs 1242 may be chamfered in the flow field rear end direction F, or the radial ribs 1244 may be chamfered in the flow field rear end direction F.
Further, an included angle m between an edge line X of the chamfer of the circumferential rib 1242 and a central line Y of the projection plane is not greater than 45 degrees, so that oil smoke can be guaranteed to flow along the edge of the circumferential rib 1242, and the central line Y of the projection plane refers to the central line of the scanning projection plane of the circumferential rib 1242. The included angle between the edge line of the chamfer angle of the radial rib 1244 and the central line of the projection plane is not more than 45 degrees, so that oil smoke can be ensured to flow along the edge of the radial rib 1244, and the central line of the projection plane refers to the central line of the scanning projection plane of the radial rib 1244.
In a specific embodiment, one end of the circumferential rib 1242 and the radial rib 1244 in the front end direction E of the flow field is in a round shape, and the other end of the circumferential rib 1242 and the radial rib 1244 in the rear end direction F of the flow field is in a reverse oblique shape. Thus, the resistance of the oil smoke flowing and the generation of local noise can be reduced, so that the whole combined cooking device 1000 can work in a better state.
Referring to fig. 4 and 5, in some embodiments, the peripheral wall 14 is provided with a plurality of peripheral wall air inlet sets 142, and each peripheral wall air inlet set 142 includes a plurality of peripheral wall air inlets 1422 arranged in a honeycomb shape.
Therefore, the air inlet resistance of the oil smoke is further reduced, and the effect of assisting in gathering the oil smoke is achieved. It is understood that, in the embodiment of the present invention, the air inlet structure 10 can be disposed at the through hole 310 of the panel 300 in a lifting manner. When the user uses the combined cooking apparatus 1000 and needs to discharge smoke, the air intake structure 10 may be raised above the panel 300 by a certain height to expose the plurality of peripheral wall air intake sets 142, thereby achieving the effect of assisting in gathering smoke. When the smoke is not exhausted, the air intake structure 10 can be lowered to the same plane as the panel 300 so that the plurality of peripheral wall air intake sets 142 are located below the panel 300.
In the illustrated embodiment, the peripheral wall air inlet 1422 is a hexagonal hole. In other embodiments, the peripheral wall air inlet 1422 may be a circular hole. Of course, the peripheral wall air inlet group 142 may also adopt a plurality of peripheral wall air inlets 1422 arranged in an array, or the peripheral wall 14 may be provided with a plurality of single air inlets.
Referring to fig. 8, in some embodiments, an angle region n formed by the air inlet axis a of the air inlet net inlets 122 and the range of the peripheral wall inlet group 142 points to the range of the cooking utensil.
Therefore, the peripheral wall air inlet group 142 can better play a role in assisting in gathering the smoke. It is understood that the position of the peripheral wall intake vent group 142 may be determined according to the installation position of the cooking appliance on the panel 300. In the illustrated embodiment, four cooking utensils are uniformly distributed on the peripheral side of the air inlet structure 10, and correspondingly, the peripheral wall 14 is provided with four peripheral wall air inlet sets 142, which correspond to the cooking utensils one to one. In other embodiments, there may be two cooking utensils, the two cooking utensils may be connected to form a straight line and located at two opposite sides of the air inlet structure 10, and correspondingly, the peripheral wall 14 is provided with two peripheral wall air inlet sets 142 corresponding to the cooking utensils one by one.
Specifically, the angle region n covers the range of the cooking utensil and is not less than the preset number r of the edge of the cooker 200 placed on the cooking utensil. Therefore, the opening range of the peripheral wall air inlet group 142 is prevented from being too small, and the auxiliary smoke gathering effect of the peripheral wall 14 is ensured. It is understood that the cooker 200 according to the present embodiment is a cooker 200 of a specific specification that is used together with a cooking appliance, and the size of the cooker 200 is fixed. Therefore, the angle area formed by the air inlet axis a of the air inlet net air inlet 122 and the range of the peripheral wall air inlet group 142 can be designed to be no less than the preset degree r of the edge of the cooker 200 placed on the cooking utensil. In one embodiment, the predetermined number of degrees r is 20 degrees.
Referring to fig. 4, in some embodiments, the air intake screen 12 is attached to the perimeter wall 14 by a turnbuckle 16.
Therefore, the air inlet net 12 and the peripheral wall 14 are simple and convenient to install. In other embodiments, the grill 12 can be attached to the peripheral wall 14 by screws, snaps 18, or other fastening means.
Referring to fig. 6, in some embodiments, the lower end of the peripheral wall 14 is provided with a latch 18 so that the air intake structure 10 is mounted on the combined cooking apparatus 1000 through the latch 18.
Thus, the installation of the air intake structure 10 and the combined cooking apparatus 1000 is simple and convenient. It is understood that the air intake structure 10 is mounted to the panel 300 by means of the latch 18 so as to be mounted to the combined cooking apparatus 1000.
