[0028] In order to further understand the content, characteristics and effects of the present application, the following examples are given, and the details are described as follows with reference to the drawings:

[0029] Please refer to Figures 1 to 4 The utility model discloses a range hood, the range hood disclosed by the utility model includes range hood main body 1, range hood main body 1 has the suction panel 11 and the smoke collecting cavity 12, is equipped with the suction port 111 that communicates with the smoke collecting cavity 12 on the suction panel 11, the lower edge of the suction port 111 extends the baffle 112 into the smoke collecting cavity 12, the baffle 112 is set to the rear inclination from below to above, the height of the upper edge of the baffle 112 is not less than the height of the upper edge of the suction port 111, and the gap between the upper edge of the baffle 112 and the upper edge of the suction port 111 forms effective suction port.

[0030] In the embodiment, the suction panel 11 is the front panel of the range hood main body 1, the smoke collecting cavity 12 is installed with the smoke exhaust fan, the smoke exhaust fan can make the suction port 111 produce negative pressure when operating, and the oil fume generated by the user cooking is sucked into the smoke collecting cavity 12 through the suction port 111 and is finally discharged by the smoke exhaust fan. The baffle 112 extends from the lower edge of the suction port 111 towards the inner side of the suction port 111, the distance between the baffle 112 and the suction panel 11 increases from the lower edge to the upper edge, the flow passage is formed between the baffle 112 and the flow cross section of the suction port 111, the flow passage communicates the suction port 111 and the effective suction port, the airflow flows into the suction port 111 first, then hits on the baffle 112, and then flows to the effective suction port along the flow passage, and then flows into the smoke collecting cavity 12 through the effective suction port.

[0031] When the user looks at the air inlet 111 on the air suction panel 11, the shielding plate 112 can shield the user's line of sight, prevent the user from directly seeing the back plate of the smoke collecting cavity 12 through the air inlet 111, and avoid affecting the user's visual perception of the range hood. Since the shielding plate 112 is arranged in a rearward inclination from bottom to top, the gap between the upper edge of the shielding plate 112 and the upper edge of the air inlet 111 forms an effective air inlet. After the oil fume flows into the air inlet 111 and hits the shielding plate 112, the oil fume can continue to flow into the smoke collecting cavity 12 upward through the effective air inlet, so that the shielding plate 112 does not affect the process of the oil fume flowing into the smoke collecting cavity 12, and the oil fume suction effect of the range hood is ensured.

[0032] In the range hood of the utility model, as shown in the figure, Figures 1 to 4 The shielding plate 112 has two connecting plates 113, the connecting plate 113 is connected with the side edge of the corresponding side of the air inlet 111, the connecting plate 113 is arc-shaped, and the upper edge of the connecting plate 113 is a first arc-shaped edge that protrudes in the direction away from the user. The number of the connecting plate 113 is two, and the two connecting plates 113 are arranged at the two ends of the shielding plate 112. Each connecting plate 113 connects the end side of the shielding plate 112 with the side edge of the air inlet 111. In this way, the shielding plate 112 and the air suction panel 11 can be connected as a whole in terms of visual perception, so as to improve the appearance integrity of the range hood. In addition, the connecting plate 113 can increase the connection position of the shielding plate 112 and the air suction panel 11, so as to improve the connection stability of the shielding plate 112 and the air suction panel 11. One side of the connecting plate 113 close to the air inlet 111 is a concave arc surface, the upper edge of the connecting plate 113 forms a concave arc edge, the spacing between the upper edge of the connecting plate 113 and the upper edge of the air inlet 111 can be increased as much as possible, so as to increase the flow area of the effective air inlet, and the air inlet amount of the effective air inlet is improved.

[0033] In the range hood of the utility model, as shown in the figure, Figure 1 The two side edges of the air inlet 111 are arc-shaped, the upper edge and the lower edge of the arc-shaped edge are connected with the corresponding end of the upper edge and the corresponding end of the lower edge of the air inlet 111 respectively, the corresponding edge of the connecting plate 113 is a second arc-shaped edge that is matched with the arc-shaped edge of the corresponding side of the air inlet 111, the upper edge of the second arc-shaped edge is connected with the corresponding end of the first arc-shaped edge, and the lower edge of the second arc-shaped edge is connected with the corresponding end of the lower edge of the air inlet 111. The two side edges of the air inlet 111 are concave arc-shaped, the second arc-shaped edges of the two connecting plates 113 are matched with the two side arc-shaped edges of the air inlet 111 respectively. In this way, the air inlet cross section of the air inlet 111 can be increased, so as to improve the air inlet amount of the air inlet 111.

[0034] In a specific application, the adapter plate 113 comprises a vertical edge connected to a corresponding side of the adapter plate 113, a first arc-shaped edge having one end connected to an upper end of the vertical edge and the other end connected to an upper end of a second arc-shaped edge, and the lower end of the second arc-shaped edge being connected to the lower end of the vertical edge, and the second arc-shaped edge being convex in a direction away from the user side.

[0035] In the smoke machine, the shielding plate 112 and the adapter plate 113 are integrally formed with the air suction panel 11. The air suction panel 11 is a sheet metal part, and the shielding plate 112 and the adapter plate 113 are both cut and stamped on the air suction panel 11. The connection between the adapter plate 113 and the air suction panel 11 and the shielding plate 112 is smoothly transitioned to ensure the appearance of the air suction panel 11. Moreover, due to the smoothly transitioned connection between the adapter plate 113 and the air suction panel 11 and the shielding plate 112, it is convenient to clean the oil stains attached to the shielding plate 112 and the adapter plate 113.

[0036] In the smoke machine, as shown in Figures 2 to 4 The smoke machine further comprises a reinforcing plate 13 arranged on the back side of the air suction panel 11, and the reinforcing plate 13 is provided with a supporting portion 131 connected to the back side of the shielding plate 112. Since the shielding plate 112 and the adapter plate 113 are integrally cut and stamped with the air suction panel 11, the reinforcing plate 13 is arranged on the back side of the air suction panel 11, and the supporting portion 131 of the reinforcing plate 13 is connected to the back side of the shielding plate 112, so as to ensure the strength of the connection between the adapter plate 113 and the shielding plate 112 and the air suction panel 11.

[0037] In the smoke machine, as shown in Figure 3 The reinforcing plate 13 is connected to the back side of the air suction panel 11, and the avoiding opening is arranged around the air suction opening 111, and the supporting portion 131 is connected to the lower edge of the avoiding opening. The avoiding opening is larger than the air suction opening 111 to avoid affecting the air inlet amount of the air suction opening 111 by the peripheral edge of the avoiding opening. When connecting the reinforcing plate 13 to the air suction panel 11, the shielding plate 112 is first passed through the avoiding opening, and then the supporting portion 131 is connected to the shielding plate 112 in the process of connecting the reinforcing plate 13 to the air suction panel 11. In this way, the connection process of the reinforcing plate 13 and the air suction panel 11 and the shielding plate 112 can be simplified to improve the assembly efficiency. The reinforcing plate 13 is arranged around the air suction opening 111, so that the reinforcing plate 13 can strengthen the parts around the air suction opening 111.

[0038] In the smoke machine, as shown in Figure 3 and Figure 4As shown, the upper edge of the reinforcing plate 13 is provided with a first oil baffle 132, and the first oil baffle 132 is arranged to tilt backward from bottom to top. When the oil smoke entering the smoke collecting chamber 12 flows through the back of the air suction panel 11, the oil will adhere to the air suction panel 11. The oil attached to the back side of the air suction panel 11 will accumulate to form oil and flow downward. The first oil baffle 132 can block the oil flowing from the top of the reinforcing plate 13 to the air suction port 111, preventing the oil from dripping onto the baffle 112 or dripping out of the air suction port 111, thereby ensuring the cleanliness of the range hood appearance and cooking environment. The distance between the first oil baffle 132 and the air suction panel 11 gradually increases from bottom to top, which can prevent the oil from dripping onto the baffle 112 after passing over the upper edge of the first oil baffle 132, further ensuring the oil blocking effect of the first oil baffle 132.

[0039] In the smoke machine of the present invention, Figure 3 and Figure 4 As shown, a second oil baffle 133 is provided at the upper edge of the avoidance port. The second oil baffle 133 is tilted backward from bottom to top, and the dimension of the second oil baffle 133 along the width direction is larger than the dimension of the air intake port 111 along the width direction. The second oil baffle 133 can block the oil flowing from above the air intake port 111 to the air intake port 111, preventing the oil from dripping onto the baffle 112 or dripping out of the air intake port 111, thereby ensuring the cleanliness and tidiness of the range hood appearance and cooking environment. The distance between the second oil baffle 133 and the air intake panel 11 gradually increases from bottom to top, which can prevent the oil from dripping onto the baffle 112 after passing over the upper edge of the second oil baffle 133, further ensuring the oil blocking effect of the second oil baffle 133. After being blocked by the second oil baffle 133, the oil will flow to the two ends of the second oil baffle 133, and will continue to flow downward after flowing through the two ends of the second oil baffle 133. The length of the second oil baffle 133 is greater than the length of the air suction port 111, which can prevent the oil that continues to flow downward from the two ends of the second oil baffle 133 from flowing to the air suction port 111, thereby further preventing the oil from dripping onto the baffle 112 or dripping out of the air suction port 111.

[0040] In the smoke machine of the present invention, Figure 5 As shown, windshields 14 are provided on the left and right sides of the range hood body 1. After the oil smoke flows toward the air intake panel 11 under the action of the negative pressure of the air intake port 111, the oil smoke that is not immediately sucked into the air intake port 111 will be blocked by the windshields 14 before escaping to the sides, preventing the oil smoke from easily spreading away from the range hood body 1, thereby improving the performance of the range hood.

[0041] In the smoke machine of the present invention, Figure 6As shown, the air suction panel 11 is vertically arranged, the upper edge of the air suction port 111 is projected backward to coincide with the upper edge of the shielding plate 112, the distance between the upper edge of the air suction port 111 and the lower edge of the air suction port 111 is D, the angle between the shielding plate 112 and the air suction panel 11 is α, the width W of the effective air suction port is D*tanα, 15mm≤W≤25mm, 15°≤α≤75°. In the side projection view of the air suction panel 11, the line connecting the upper edge of the air suction port 111 and the upper edge of the shielding plate 112 and the air suction panel 11 and the shielding plate 112 together form a right triangle, according to the trigonometric function, W=D*tanα, the width W of the effective air suction port is set to 15mm≤W≤25mm, and the angle α between the shielding plate 112 and the air suction panel 11 is set to 15°≤α≤75°, so that the width of the effective air suction port is more reasonable, which can not only ensure the air intake of the effective air suction port, but also avoid that the upper edge of the shielding plate 112 is too far away from the air suction panel 11.

[0042] As shown in the smoke machine of the utility model, Figure 7 As shown, the air suction panel is arranged backwardly inclined from top to bottom, the angle between the air suction panel and the vertical plane is β, the upper edge of the air suction port is projected backward to coincide with the upper edge of the shielding plate, the distance between the upper edge of the air suction port and the lower edge of the air suction port is D, the angle between the shielding plate and the air suction panel is α, the width W of the effective air suction port is D*sinβ+D*cosβ*tan(α-β), 15mm≤W≤25mm, 15°≤α≤75°, 0°<β<45°, β<α.

[0043] A vertical reference plane passing through the lower edge of the air suction port 111 is defined, the vertical reference plane is located between the shielding plate 112 and the air suction panel 11, the angle between the shielding plate 112 and the vertical reference plane is α-β, the width W of the effective air suction port is composed of W1+W2, wherein W1 is the distance between the upper edge of the air suction port 111 and the vertical reference plane, and W2 is the distance between the upper edge of the shielding plate 112 and the vertical reference plane, according to the trigonometric function, W1=D*sinβ, W2=H*tan(α-β), wherein H is the height of the air suction port, and under the condition that D and β are known, it is known that H=D*cosβ, therefore, W2=D*cosβ*tan(α-β), and thus W=W1+W2=D*sinβ+D*cosβ*tan(α-β) can be deduced. The width W of the effective air suction port is set to 15mm≤W≤25mm, the angle α between the shielding plate 112 and the air suction panel 11 is set to 15°≤α≤75°, and the angle β between the air suction panel and the vertical plane is set to 0°<β<45°, so that the width of the effective air suction port is more reasonable, which can not only ensure the air intake of the effective air suction port, but also avoid that the upper edge of the shielding plate 112 is too far away from the air suction panel 11.

[0044] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement or improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
