Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to a range hood. Background Art

[0002] In order to prevent oil smoke from escaping and improve the oil smoke absorption effect, the range hoods currently on the market usually adopt a smoke collection cavity shape, but the design and manufacturing of the smoke collection cavity shape is relatively complex. In addition, the oil smoke absorption effect can also be improved by adding an external smoke collection plate or an air curtain, but the addition of an external smoke collection plate will cause the oil smoke to condense on the surface, which is not conducive to daily cleaning. At the same time, it will take up space and cause users to bump their heads. Adding an air curtain will increase costs and generate noise during use. In order to separate the oil smoke and prevent oil droplets from dripping directly, the range hood currently mainly uses an oil net to control it, but a sparse oil net will make the oil smoke separation unclean, and an overly dense oil net will increase the resistance of the air inlet, which is not conducive to the oil smoke absorption effect.

[0003] Range hoods currently on the market may have one or more air inlets. When multiple air inlets are provided, during the cooking process, the airflows between the multiple air inlets may affect each other, thus affecting the range hood extraction effect. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a range hood in order to overcome the defect of oil smoke escape of the prior art range hood.

[0005] The utility model solves the above technical problems through the following technical solutions:

[0006] The utility model provides a range hood, which comprises a smoke collecting hood, a first guide plate and a second guide plate;

[0007] The smoke collecting hood comprises a smoke collecting cavity and an air inlet plate, and the air inlet plate is provided with a first air inlet and a second air inlet;

[0008] The first guide plate and the second guide plate are arranged in the smoke collecting chamber at intervals, and the first guide plate and the second guide plate divide the smoke collecting chamber into a first air duct and a second air duct, and the second air duct is located between the first guide plate and the second guide plate;

[0009] The first air inlet is connected to the first air duct and the outside, and the second air inlet is connected to the second air duct and the outside.

[0010] In this solution, the first guide plate and the second guide plate are provided at the internal interval of the smoke collecting hood of the range hood. The first guide plate and the second guide plate divide the smoke collecting chamber into the first air duct and the second air duct. The first air inlet connects the first air duct and the outside, and the second air inlet connects the second air duct and the outside, so that the range hood has a double air duct. The oil smoke from the outside is sucked into the first air duct and the second air duct through the first air inlet and the second air inlet respectively, which can reduce the influence of the airflow between multiple air inlets, improve the oil smoke absorption effect, and prevent the oil smoke from escaping. The range hood does not need to be provided with a smoke collecting chamber with a complex shape, and an external smoke collecting plate or wind curtain is added to improve the oil smoke absorption effect. It is easier to manufacture, occupies less space and has lower noise. At the same time, the first guide plate and the second guide plate can guide the oil smoke to gather, play the role of collecting oil smoke, and prevent the oil smoke from dripping directly. It can replace the oil net in the prior art and avoid the influence of the oil net on the smoking effect.

[0011] Preferably, the range hood further comprises a body and a fan, and the first air guide plate comprises a protrusion;

[0012] The fan is arranged inside the fuselage, and the protrusion at least partially extends into the interior of the fuselage.

[0013] In this solution, the protruding portion of the first guide plate at least partially extends into the interior of the fuselage, and a fan is provided in the fuselage, so that the oil smoke can be directed to the fan, thereby achieving a better smoking effect.

[0014] Preferably, the smoke collecting hood further comprises an upper surface, and the first guide plate further comprises a first main body and a first upper flange provided on a side of the first main body close to the upper surface;

[0015] The first upper flange is fixed to the upper surface.

[0016] In this solution, the above-mentioned structural form is adopted to enable the first guide plate to be fixed to the smoke collecting hood.

[0017] Preferably, the first air guide plate further comprises a first lower flange provided on a side of the first body close to the air inlet plate;

[0018] The first lower flange extends toward the air inlet plate, and a notch is provided at the bottom center of the first lower flange.

[0019] In this solution, the first lower flange extends toward the air inlet plate, which is beneficial for the first lower flange to guide the oil droplets condensed from the oil smoke toward the air inlet plate, and is more beneficial for the oil droplets to gather on the air inlet plate. The oil droplets can be collected more effectively, and the gathered oil droplets can pass through the gap in the bottom center of the first lower flange.

[0020] Preferably, the air inlet plate is inclined downward from the front side of the range hood to the rear side of the range hood;

[0021] The included angle between the upper surface and the air inlet plate is θ1, where 10° < θ1 < 45°; and / or,

[0022] The included angle between the upper surface and the first main body is θ2, where 0° < θ2 < 45°.

[0023] In this solution, the air inlet plate is inclined obliquely downward from the front side to the rear side of the range hood, so that the oil droplets can slide down along the air inlet plate into the oil cup. θ1 > 10° can ensure that the oil droplets can flow on the air inlet plate, and θ1 < 45° can avoid interference between the air inlet plate and the cooking range or cookware due to too large an inclination angle of the air inlet plate. At the same time, it can also prevent bumping during use and the phenomenon of oil dripping from the air inlet plate due to too large an angle. 0° < θ2 < 45° can ensure that the deflector is inclined backward, and can guide the oil fume backward into the fan, improving the oil fume suction effect.

[0024] Preferably, the width of the first upward flanging is w1, and the width of the first main body is w2;

[0025] 0.2w2 < w1 < 0.5w2; and / or,

[0027] The air inlet plate is further provided with a groove recessed into the smoke collecting cavity. The first air inlet and the second air inlet are arranged on the top wall of the groove on the side close to the front side of the range hood, and the distance from the edge of the first air inlet to the front side wall of the groove is x;

[0028] w2 < (h2 + xsinθ1 + h) / sinθ2; and / or,

[0029] The width of the first main body is w2, the first downward flanging is w3, the included angle between the upper surface and the air inlet plate is θ1, the included angle between the upper surface and the first main body is θ2, the widths of the first air inlet and the second air inlet are d, and the minimum height of the smoke collecting cavity is h;

[0030] w2 > (dcosθ1 / cosθ2) and 0 < w3 < 0.5h / cosθ1.

[0031] In this solution, 0.2w2 < w1, so that the first upward turning edge has enough width to be fixed to the upper surface of the smoke collecting hood. w1 < 0.5w2 can ensure that the first upward turning edge will not extend into the air inlet of the fuselage to block the air inlet path. The air inlet plate is also provided with a groove recessed towards the smoke collecting cavity, so that the oil fume can gather in the groove, and the smoke collecting effect is better. w2 < (h2 + xsinθ1 + h) / sinθ2 ensures that the first deflector can be placed inside the smoke collecting hood. w2 > (dcosθ1 / cosθ2) and 0 < w3 < 0.5h / cosθ1 ensure that the bending position of the first downward turning edge is outside the air inlet, preventing oil droplets from easily dripping at the position directly above the air inlet where the bending is located.

[0032] Preferably, the width of the protruding part is w4, the distance from the lowest point of the volute of the fan to the upper surface is h2, and the included angle between the upper surface and the first main body is θ2;

[0033] 0 < w4 < h2 / sinθ2.

[0034] In this solution, the width of the protruding part satisfies w4 < h2 / sinθ2, which can ensure that the first deflector and the volute of the fan do not interfere.

[0035] Preferably, the range hood further includes a control panel;

[0036] The control panel is arranged at the front side part of the smoke collecting cavity, and the second deflector separates the control panel from the second air duct.

[0037] In this solution, adopting the above structural form enables the second deflector to separate the control panel from the oil fume, avoiding the control panel being affected by the oil fume.

[0038] Preferably, the smoke collecting hood further includes an upper surface, and the second deflector includes a second main body and a second upward turning edge arranged on one side of the second main body close to the upper surface;

[0039] The second upward turning edge is fixed to the upper surface; and / or,

[0040] The second deflector further includes a second downward turning edge arranged on one side of the second main body close to the air inlet plate;

[0041] The second downward turning edge extends towards the air inlet plate.

[0042] In this solution, the second upward turning edge is used to fix the second deflector to the upper surface of the smoke collecting hood, and the second downward turning edge is used to deflect the oil droplets condensed from the oil fume towards the air inlet plate, which is more conducive to the oil droplets gathering on the air inlet plate.

[0049] In this solution, 0.2t2 < t1, so that the second upward flanging has enough width to be fixed on the upper surface of the smoke collecting hood, and t1 < 0.5t2 can ensure that the second upward flanging does not extend into the air inlet of the fuselage to block the air inlet path. t2 < h / sinθ2 can ensure that the second deflector can be placed inside the smoke collecting hood. t2 > 0.6h / sinθ2 and 0 < t3 < 0.5h / cosθ1 can ensure that the bending position of the second downward flanging is outside the air inlet, preventing oil droplets from easily dripping directly above the air inlet, and at the same time enhancing the deflector effect.

[0050] The positive and progressive effects of the present utility model are as follows:

[0051] The present utility model provides an oil fume suction machine. A first deflector and a second deflector are arranged at intervals in the smoke collecting cavity of the oil fume suction machine. The first deflector and the second deflector divide the interior of the smoke collecting hood into a first air duct and a second air duct. The first air inlet communicates the first air duct with the outside, and the second air inlet communicates the second air duct with the outside. Thus, the oil fume suction machine has a double air duct. The outside oil fume is respectively sucked into the first air duct and the second air duct through the first air inlet and the second air inlet, which can reduce the influence of the air flow between multiple air inlets, improve the oil fume suction effect, and prevent oil fume from escaping. The oil fume suction machine does not need to set a smoke collecting cavity with a complex shape, add an external smoke collecting plate or an air curtain to improve the oil fume suction effect, is more convenient to manufacture, occupies less space and has lower noise.

[0084] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0085] like Figure 1-Figure 4 As shown, the present embodiment provides a range hood 100, which includes a smoke hood 200, a body 400, a fan 410, a control panel 500, a first guide plate 310 and a second guide plate 320. The smoke hood 200 is arranged below the body 400, the fan 410 is arranged inside the body 400, and the first guide plate 310 and the second guide plate 320 are arranged inside the smoke hood 200.

[0086] The smoke collecting hood 200 comprises a smoke collecting chamber 210, an upper surface 230 and an air inlet plate 220, and the air inlet plate 220 is provided with a first air inlet 221 and a second air inlet 222. The first guide plate 310 and the second guide plate 320 are arranged in the smoke collecting chamber 210 at intervals, and the first guide plate 310 and the second guide plate 320 divide the smoke collecting chamber 210 into a first air duct 211 and a second air duct 212, and the second air duct 212 is located between the first guide plate 310 and the second guide plate 320. The first air inlet 221 connects the first air duct 211 with the outside, and the second air inlet 222 connects the second air duct 212 with the outside, so that the range hood 100 has a double air duct, and the oil smoke in the outside is sucked into the first air duct 211 and the second air duct 212 through the first air inlet 221 and the second air inlet 222 respectively, which can reduce the influence of the air flow between the multiple air inlets, improve the oil smoke absorption effect, and prevent the oil smoke from escaping. The range hood 100 does not need to be provided with a complex-shaped smoke collecting chamber, and an external smoke collecting plate or wind curtain is added to improve the oil fume extraction effect. It is easier to manufacture, occupies less space and has lower noise. At the same time, the first guide plate 310 and the second guide plate 320 can guide the oil fume to gather and collect the oil fume to prevent the oil fume from dripping directly. It can replace the oil net in the prior art and avoid the influence of the oil net on the smoking effect.

[0087] The control panel 500 is disposed at the front side 610 of the smoke collecting chamber 210 , and the second guide plate 320 separates the control panel 500 from the second air duct 212 , so that the second guide plate 320 can separate the control panel 500 from the oil smoke, thereby preventing the control panel 500 from being affected by the oil smoke.

[0088] like Figure 1 As shown, the front side 610 refers to the side where the user is located, and the opposite side is the rear side 620. The air inlet plate 220 slopes obliquely downward from the front side 610 of the range hood 100 to the rear side 620 of the range hood 100, so that the oil droplets can slide down along the air inlet plate 220 and enter the oil cup.

[0089] The included angle between the upper surface 230 and the air inlet plate 220 is θ1, and 10° < θ1 < 45°. θ1 > 10° can ensure that the oil droplets can flow on the air inlet plate 220, and θ1 < 45° can prevent the air inlet plate 220 from interfering with the cooking range or cookware due to too large an inclination angle of the air inlet plate 220. At the same time, it can also prevent hitting the head during use and the oil dripping phenomenon of the air inlet plate 220 due to too large an angle.

[0090] The included angle between the upper surface 230 and the first main body 311 is θ2, and 0° < θ2 < 45°. 0° < θ2 < 45° can ensure that the deflector plate slopes backward to the rear side 620, and can guide the oil fume to the rear side 620 and enter the fan 410, improving the oil fume suction effect.

[0091] As Figure 5 shown, the first deflector plate 310 includes a protruding portion 314, and at least part of the protruding portion 314 extends into the interior of the body 400. A fan 410 is provided in the body 400, so that the oil fume can be deflected to the fan 410, making the smoking effect better.

[0092] The first deflector plate 310 further includes a first main body 311 and a first upward flange 312 provided on the side of the first main body 311 close to the upper surface 230. The first upward flange 312 is fixed to the upper surface 230, so that the first deflector plate 310 can be fixed to the smoke collecting hood 200.

[0093] The first deflector plate 310 further includes a first downward flange 313 provided on the side of the first main body 311 close to the air inlet plate 220. The first downward flange 313 extends in the direction of the air inlet plate 220, and a notch 315 is provided at the center of the bottom of the first downward flange 313. The first downward flange 313 extends in the direction of the air inlet plate 220, which is beneficial for the first downward flange 313 to deflect the oil droplets condensed from the oil fume in the direction of the air inlet plate 220, and is more beneficial for the oil droplets to gather on the air inlet plate 220, and the oil droplets can be more effectively collected. The gathered oil droplets can pass through the notch 315 at the center of the bottom of the first downward flange 313.

[0094] In this embodiment, the width of the first upward flange 312 is w1, and the width of the first main body 311 is w2, and 0.2w2 < w1 < 0.5w2. 0.2w2 < w1, so that the first upward flange 312 has enough width to be fixed to the upper surface 230 of the smoke collecting hood 200, and w1 < 0.5w2 can ensure that the first upward flange 312 does not extend into the air inlet of the body 400 to block the air inlet path.

[0095] The minimum height of the smoke collecting cavity 210 is h, and the distance from the lowest point of the volute of the fan 410 to the upper surface 230 is h2. The air inlet plate 220 is further provided with a groove 223 recessed towards the smoke collecting cavity 210, so that oil fume can be gathered in the groove 223, and the effect of gathering smoke is better. The first air inlet 221 and the second air inlet 222 are arranged on one side of the top wall of the groove 223 close to the front side 610 of the range hood 100. The distance from the edge of the first air inlet 221 to the front side 610 wall of the groove 223 is x, and the width w2 of the first main body 311 needs to satisfy: w2 < (h2 + xsinθ1 + h) / sinθ2. w2 < (h2 + xsinθ1 + h) / sinθ2 can ensure that the first deflector 310 can be placed inside the smoke collecting hood 200.

[0096] In this embodiment, the first downward turning edge 313 is w3, and the widths of the first air inlet 221 and the second air inlet 222 are d. w2 > (dcosθ1 / cosθ2) and 0 < w3 < 0.5h / cosθ1, so as to ensure that the bending position of the first downward turning edge 313 is outside the air inlet, preventing oil droplets from easily dripping at the position directly above the air inlet.

[0097] The width of the protruding portion 314 is w4, and 0 < w4 < h2 / sinθ2. The width of the protruding portion 314 satisfying w4 < h2 / sinθ2 can ensure that there is no interference between the first deflector 310 and the volute of the fan 410.

[0098] As Figure 6 shown, the second deflector 320 includes a second main body 321 and a second upward turning edge 322 provided on one side of the second main body 321 close to the upper surface 230, and the second upward turning edge 322 is fixed to the upper surface 230. The second deflector 320 further includes a second downward turning edge 323 provided on one side of the second main body 321 close to the air inlet plate 220, and the second downward turning edge 323 extends towards the air inlet plate 220. The second upward turning edge 322 is used to fix the second deflector 320 to the upper surface 230 of the smoke collecting hood 200, and the second downward turning edge 323 is used to deflect the oil droplets condensed from the oil fume towards the air inlet plate 220, which is more conducive to the collection of oil droplets on the air inlet plate 220.

[0099] The width of the second upward turning edge 322 is t1, and the width of the second main body 321 is t2. 0.2t2 < t1 < 0.5t2. 0.2t2 < t1, so that the second upward turning edge 322 has enough width to be fixed to the upper surface 230 of the smoke collecting hood 200, and t1 < 0.5t2 can ensure that the second upward turning edge 322 does not extend into the air inlet of the fuselage 400 to block the air inlet path.

[0100] The included angle between the upper surface 230 and the second main body 321 is θ2, the minimum height of the smoke collecting cavity 210 is h, and t2 < h / sinθ2. t2 < h / sinθ2 can ensure that the second deflector 320 can be placed inside the smoke collecting hood 200.

[0101] The width of the second downward turned edge 323 is t3, t2 > 0.6h / sinθ2 and 0 < t3 < 0.5h / cosθ1, so as to ensure that the bending position of the second downward turned edge 323 is outside the air inlet, prevent oil droplets from easily dripping directly above the air inlet at the bending position, and at the same time enhance the guiding effect.
