Abstract
Description
Technical Field
[0001] This utility model belongs to the field of integrated stoves, specifically a wing-shaped air guide device and an integrated stove. Background Technology
[0002] The head of an integrated cooktop is the main channel through which cooking fumes enter its interior. If the flow channel design at the head of the cooktop is unbalanced or non-smooth, the flow of cooking fumes within the channel will be obstructed, severely disrupting the fume flow. This disruption not only affects the efficiency of fume flow but may also cause unnecessary vortices to form in the middle or sides of the flow channel. The presence of these vortices creates additional resistance as the fumes enter the flow channel, increasing the difficulty of fume flow and thus reducing the efficiency of fume emission.

[0039] This application provides an airfoil-shaped flow guide device. When applied to the smoke collection chamber of an integrated stove, the airfoil-shaped flow guide device accelerates the flow velocity of incoming smoke, reduces the flow resistance of smoke in the smoke collection chamber, thereby reducing airflow turbulence and preventing vortex formation, thus improving the smoke collection effect of the smoke collection chamber.
[0040] Figure 1 This is a cross-sectional schematic diagram of an airfoil-shaped flow guide device placed in a smoke collection chamber, according to an embodiment of this application. Figure 2 This is a schematic diagram of an airfoil guide device provided in an embodiment of this application, as shown below. Figure 1 and Figure 2 As shown, the airfoil guide device includes an airfoil guide vane 1. The airfoil guide vane 1 includes flat plates 11 connected in sequence. Figure 1 (As shown in section AB), first inclined panel 12 ( Figure 1 (as shown in segment BC), arc panel 13 ( Figure 1 The CD segment shown) and the second inclined panel 14 ( Figure 1 (Segment DE shown). The included angle between the flat plate 11 and the first inclined plate 12 is an obtuse angle, and the first inclined plate 12 and the second inclined plate 14 are tangent to the arc plate 13, respectively. The airfoil guide plate 1 is used to interact with the smoke baffle 2 of the integrated stove ( Figure 1 The AF segment shown is arranged opposite to each other, with the flat plate 11 and the second inclined plate 14 respectively used to contact the upper and lower ends of the smoke baffle 2. Points A and B are located on the X-axis, and points E and F are located on the Y-axis.
[0041] In this embodiment, the arc panel 13 between the first inclined panel 12 and the second inclined panel 14 reduces the flow resistance of oil fumes in the smoke collection chamber. By placing the flat plate 11 perpendicular to the smoke baffle 2, the inlet width of the oil fumes is shortened and the inlet flow velocity of the oil fumes is accelerated, thereby avoiding vortex formation and improving the smoke collection effect of the smoke collection chamber. In addition, this airfoil-shaped flow guide device can also reduce the aerodynamic noise caused by vortices.
[0042] In this embodiment, the airfoil-shaped flow guide device is installed in the smoke collection chamber of the integrated stove, with the airfoil-shaped flow guide device positioned opposite to the smoke baffle 2 located in the integrated stove. The flat plate 11 of the airfoil-shaped flow guide device is placed perpendicular to the smoke baffle 2, and the tops of the flat plate 11 and the smoke baffle 2 are at the same horizontal height. The second inclined plate 14 of the airfoil-shaped flow guide device is in contact with the lower end of the smoke baffle 2, and the bottom end of the second inclined plate 14 is higher than the bottom end of the smoke baffle 2. The fumes enter the smoke collection chamber from the smoke inlet above the smoke baffle 2 along the flat plate 11. Under the action of the fan located at the bottom of the integrated stove, the fumes flow downwards in the smoke collection chamber along the curved surface of the airfoil-shaped flow guide 1.
[0043] In this embodiment of the application, in order to achieve the purpose of improving the smoke collection effect of the integrated stove by using the airfoil guide device, the airfoil guide plate 1 is designed as follows: Figure 1 The airfoil shape shown is designed with the following two main points in mind: First, to ensure the airfoil-guiding effect of the first inclined panel 12, the arc panel 13, and the second inclined panel 14, especially to ensure the guiding effect of the arc panel 13 located between the first inclined panel 12 and the second inclined panel 14 on the oil fumes; Second, to control the length of the flat plate 11 within a certain range to shorten the inlet width of the oil fumes entering the smoke collection chamber, thereby accelerating the inlet flow rate of the oil fumes.
[0044] In the embodiments of this application, such as Figure 1 As shown, the airfoil guide plate 1 consists of a flat plate 11, a first inclined plate 12, an arc plate 13, and a second inclined plate 14 connected in sequence, with both ends of the airfoil guide plate 1 contacting the upper and lower ends of the smoke baffle plate 2, respectively. This structural design helps the fumes flow from the upper end to the lower end of the smoke baffle plate 2 along the direction of the airfoil guide plate 1.
[0045] In this embodiment, by setting an obtuse angle between the flat plate 11 and the first inclined plate 12 and controlling the obtuse angle within a certain range, it helps the oil fumes to flow more smoothly from the flat plate 11 to the first inclined plate 12 and flow downward along the first inclined plate 12.
[0046] In this embodiment of the application, the included angle α between the flat plate 11 and the first inclined plate 12 is 100-105 degrees.
[0047] Optionally, the included angle α between the flat plate 11 and the first inclined plate 12 is 100 degrees; optionally, the included angle α between the flat plate 11 and the first inclined plate 12 is 102.5 degrees; optionally, the included angle α between the flat plate 11 and the first inclined plate 12 is 105 degrees.
[0048] In this embodiment, due to the obtuse angle between the flat plate 11 and the first inclined plate 12, the first inclined plate 12 in the airfoil guide vane 1 gradually moves away from the smoke baffle 2 from top to bottom. To ensure that the bottom end of the airfoil guide vane 1 contacts the smoke baffle 2, components that gradually approach the smoke baffle 2 need to be connected below the first inclined plate 12. Therefore, an arc plate 13 and a second inclined plate 14 are sequentially connected to the first inclined plate 12 below it, and the second inclined plate 14 gradually approaches and contacts the smoke baffle 2 from top to bottom. By providing the arc plate 13 and the second inclined plate 14 below the first inclined plate 12, it helps the fumes to flow smoothly from the first inclined plate 12 to the second inclined plate 14 and continue flowing downwards along the second inclined plate 14.
[0049] In this embodiment of the application, when the flat plate 11 is placed in the horizontal direction, the included angle β between the second inclined plate 14 and the vertical direction is 20-30 degrees.
[0050] Optionally, the angle β between the second inclined panel 14 and the vertical direction is 20 degrees; optionally, the angle β between the second inclined panel 14 and the vertical direction is 25 degrees; optionally, the angle β between the second inclined panel 14 and the vertical direction is 30 degrees.
[0051] In this embodiment, since the flow direction of the fumes changes dramatically from the first inclined panel 12 to the second inclined panel 14, it is necessary to provide a transition plate between the first inclined panel 12 and the second inclined panel 14 to reduce the resistance encountered by the fumes during their flow. This allows the first inclined panel 12 to smoothly transition to the second inclined panel 14. For this purpose, an arc panel 13 is provided between the first inclined panel 12 and the second inclined panel 14. The smooth arc surface of the arc panel 13 allows the fumes to flow more easily from the first inclined panel 12 to the second inclined panel 14, thereby reducing the resistance encountered by the fumes during their flow.
[0052] In this embodiment, the first inclined panel 12 and the second inclined panel 14 are tangent to the arc panel 13, respectively. After determining the positions of the first inclined panel 12 and the second inclined panel 14 in the airfoil guide vane 1, arc panels 13 with different curvatures can be designed between the first inclined panel 12 and the second inclined panel 14 as required.
[0053] In some possible embodiments, the cross-section of the arc panel 13 is a circular arc segment. The ratio of the radius length r of the circular arc segment to the width d of the smoke collection chamber is 0.5-0.6. Based on the positions of the first inclined panel 12 and the second inclined panel 14 in the airfoil guide vane 1 and the radius length of the circular arc segment, the corresponding arc panel 13 can be designed.
[0054] Optionally, the ratio of the radius length r of the arc segment to the width d of the smoke collection chamber is 0.5; optionally, the ratio of the radius length r of the arc segment to the width d of the smoke collection chamber is 0.55; optionally, the ratio of the radius length r of the arc segment to the width d of the smoke collection chamber is 0.6.
[0055] In some possible embodiments, the cross-section of the arc panel 13 is an elliptical arc segment.
[0056] In some possible embodiments, the cross-section of the arc panel 13 is an arc segment formed by connecting multiple circular arc segments with corresponding different radii.
[0057] In some possible embodiments, such as Figure 1 As shown, the coordinates of point A are set to (0,0), the direction of segment AB is the positive X direction, and the direction of segment AE is the positive Y direction. The coordinates of point O are set to (-5.9,13.6). With point O as the center, and given α and β, the arc segment CD can be determined, that is, the arc panel 13 connecting the first inclined panel 12 and the second inclined panel 14 can be determined.
[0058] In this embodiment of the application, the ratio of the length of the planar plate 11 (i.e. the length of segment AB) to the width d of the smoke collection chamber is 0.25-0.45.
[0059] Optionally, the ratio of the length of the flat plate 11 (i.e. the length of segment AB) to the width d of the smoke collection chamber is 0.25; the ratio of the length of the flat plate 11 (i.e. the length of segment AB) to the width d of the smoke collection chamber is 0.35; and the ratio of the length of the flat plate 11 (i.e. the length of segment AB) to the width d of the smoke collection chamber is 0.45.
[0060] In some possible embodiments, since the curved shape has a better guiding effect, the first inclined panel 12 and the second inclined panel 14 can also be made into curved panels. However, since the manufacturing process of curved panels is more demanding, in order to reduce manufacturing costs, curved panels can also be used only at the critical position of angle transition between the first inclined panel 12 and the second inclined panel 14.
[0061] In this embodiment of the application, when the flat plate 11 is placed in the horizontal direction, the height of the airfoil guide plate 1 in the vertical direction is less than the height of the smoke baffle 2.
[0062] In this embodiment, the thickness of the airfoil deflector 1 is 0.5-1 mm. To save materials and reduce costs, the thickness of the airfoil deflector 1 does not need to be too large; it is sufficient to ensure the strength of the airfoil deflector 1.
[0063] Optionally, the thickness of the airfoil deflector 1 is 0.5 mm; optionally, the thickness of the airfoil deflector 1 is 0.75 mm; optionally, the thickness of the airfoil deflector 1 is 1 mm.
[0064] In some possible embodiments, the flat plate 11, the first inclined plate 12, the arc plate 13, and the second inclined plate 14 in the airfoil deflector 1 can be designed as an integral connection or a detachable connection.
[0065] In some possible embodiments, the included angle between the flat plate 11 and the first inclined plate 12 can be adjusted within a certain range, and the included angle between the second inclined plate 14 and the smoke baffle 2 can be adjusted within a certain range.
[0066] In this embodiment, the wing-shaped flow guide device is applied to the smoke collection chamber of the integrated stove. By placing the flat plate 11 and the smoke baffle 2 perpendicularly, the flow rate of the smoke inlet can be accelerated by shortening the width of the smoke inlet, thereby enhancing the smoke collection effect.
[0067] In this embodiment, the airfoil guide device is applied to the smoke collection chamber of the integrated stove. Since the airfoil guide device adopts a curved surface design that has a good effect on guiding oil fumes (especially the presence of the arc panel 13 between the first inclined panel 12 and the second inclined panel 14), it can reduce the flow resistance of oil fumes in the smoke collection chamber, avoid the formation of vortex, thereby enhancing the smoke collection effect and helping to improve the operating efficiency of the fan system.
[0068] In this embodiment, the airfoil-shaped flow guide device is applied to the smoke collection chamber of the integrated stove to avoid vortex formation. Since the disturbance, movement, and rupture of the internal wall of the smoke collection chamber by the vortex will generate aerodynamic noise, the airfoil-shaped flow guide device avoids the noise caused by the vortex by preventing vortex formation.

The wing-shaped flow guide device 1 and the smoke baffle 2 are arranged opposite to each other, the top of the flat plate 11 and the top of the smoke baffle 2 are on the same horizontal plane, and the bottom of the second inclined plate 14 is higher than the bottom of the smoke baffle 2.
[0071] In this embodiment, the airfoil-shaped flow guide device 1 is shaped like an airplane wing. The length H of the airfoil-shaped flow guide device 1 is the same as the length of the inner wall of the integrated stove head 31.

The two ends of the exhaust hood 335 are aligned with the outlet of the volute 334 and the smoke exhaust port 331, respectively.
