Description

Technical Field

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

[0002] A range hood generally includes a smoke collecting hood and a fan hood. The smoke collecting hood forms a smoke collecting cavity. The air inlet of the fan hood is located above the smoke collecting hood and communicates with the smoke collecting cavity. A fan is arranged in the fan hood. When the fan is working, the smoke will be sucked into the smoke collecting cavity, enter the fan hood from the top of the smoke collecting cavity, and then be discharged to the outside.

[0003] In the related art, the length and width of the smoke hood usually match the stove, resulting in a larger length of the smoke hood, and thus the space inside the smoke hood is also larger in the length direction. The fan hood usually only needs to adapt to the fan, and the size of the fan hood in the length direction of the smoke hood is smaller than that of the smoke hood.

[0004] With the above-mentioned arrangement of the range hood, after the oil smoke enters the smoke hood, it will diffuse inside the smoke hood and then enter the fan hood. This will cause the oil smoke to fail to quickly enter the fan hood and thus fail to be quickly discharged outdoors, which will affect the smoke extraction effect of the range hood and further affect the user experience of the range hood. Utility Model Content

[0005] An embodiment of the utility model provides a range hood for improving the user experience of the range hood.

[0006] To achieve the above-mentioned object, in the first aspect of the present application, a range hood is provided, comprising a fan cover, a fan, a smoke collecting hood and a guide plate assembly. The fan cover is formed with an air inlet channel. The fan is arranged in the air inlet channel, and is used to discharge the oil smoke in the air inlet channel to the outside. The smoke collecting hood is formed with a smoke collecting chamber and a smoke inlet connected to the smoke collecting chamber, and the smoke inlet is connected to the outside of the range hood. The fan cover is connected to the top of the smoke collecting hood, and the air inlet channel is connected to the smoke collecting chamber. The guide plate assembly is arranged in the smoke collecting chamber. The guide plate assembly comprises a first guide plate and a second guide plate. The first guide plate, the first guide plate is arranged at one side edge of the smoke inlet in the first horizontal direction, and the first horizontal direction is parallel to the plane where the smoke inlet is located. The first guide plate is connected to the front wall surface of the smoke collecting hood, and is connected to the air inlet of the air inlet channel, and the smoke inlet is opened on the front wall surface of the smoke collecting hood. The second guide plate, the second guide plate is arranged at the other side edge of the smoke inlet in the first horizontal direction. The second guide plate is connected to the front wall surface of the smoke collecting hood and is connected to the air inlet of the air inlet channel.

[0007] Through the above-mentioned configuration, the air inlet channel in the fan cover is connected with the smoke collecting chamber in the smoke collecting hood, and the smoke inlet on the smoke collecting chamber is connected with the outside of the range hood. Through the configuration of the fan in the air inlet channel, the oil smoke can flow through the smoke collecting chamber, the air inlet channel, and the fan in sequence under the action of the fan and then be discharged to the outdoors, thereby realizing the removal of indoor oil smoke.

[0008] Through the arrangement of the guide plate assembly, when the oil smoke flows in the smoke collecting chamber, since the first guide plate and the second guide plate are respectively arranged at the two opposite edges of the smoke inlet in the first horizontal direction, after the oil smoke is sucked into the smoke collecting chamber, it will first flow between the first guide plate and the second guide plate. Since the first guide plate and the second guide plate are both connected to the air inlet of the air inlet channel, under the action of the fan, most of the oil smoke will flow along the first guide plate and the second guide plate, and then enter the air inlet channel.

[0009] In this way, under the guidance of the first guide plate and the second guide plate, most of the oil smoke will not diffuse in the smoke collecting chamber, which can increase the rate at which the oil smoke in the smoke collecting chamber enters the air inlet channel, thereby improving the smoke extraction effect of the range hood and improving the user experience of the range hood.

[0010] In some embodiments of the present application, one end of the first guide plate close to the rear wall of the smoke hood is connected to the rear wall of the smoke hood. And / or one end of the second guide plate close to the rear wall of the smoke hood is connected to the rear wall of the smoke hood.

[0011] With the above arrangement, there is no gap between the first guide plate and the rear wall of the fume hood. When the oil smoke enters between the first guide plate and the second guide plate, the oil smoke will not flow from the end of the first guide plate close to the rear wall of the fume hood to the side of the first guide plate away from the second guide plate. In this way, more oil smoke can flow into the air inlet channel along the first guide plate and the second guide plate, so as to improve the guiding effect of the guide plate assembly on the oil smoke.

[0012] There is no gap between the second guide plate and the rear wall of the smoke hood. When the oil smoke enters between the first guide plate and the second guide plate, the oil smoke will not flow from the end of the second guide plate close to the rear wall of the smoke hood to the side of the second guide plate away from the first guide plate. In this way, more oil smoke can flow into the air inlet channel along the first guide plate and the second guide plate, so as to improve the guiding effect of the guide plate assembly on the oil smoke.

[0013] In some embodiments of the present application, the first guide plate includes a first sub-plate and a second sub-plate. The first sub-plate is located at a side edge of the smoke inlet in the first horizontal direction. One end of the second sub-plate is connected to one end of the first sub-plate close to the fan cover, and the other end of the second sub-plate is connected to the air inlet of the air inlet channel, and the other end of the second sub-plate is closer to the second guide plate than one end of the second sub-plate. And / or, the second guide plate includes a third sub-plate and a fourth sub-plate. The third sub-plate is located at a side edge of the smoke inlet in the first horizontal direction. One end of the fourth sub-plate is connected to one end of the first sub-plate close to the fan cover, and the other end of the fourth sub-plate is connected to the air inlet of the air inlet channel. The other end of the fourth sub-plate is closer to the first guide plate than one end of the fourth sub-plate.

[0014] Through the above-mentioned settings, through the settings of the first sub-plate and the second sub-plate, after entering the smoke collecting chamber, the oil smoke will first flow between the first sub-plate and the second guide plate, and then flow to the air inlet of the air inlet channel. The oil smoke located on the side of the first sub-plate close to the smoke inlet can flow along the first sub-plate and the second sub-plate toward the air inlet close to the air inlet of the air inlet channel. Since the other end of the second sub-plate is closer to the second guide plate than one end of the second sub-plate, this part of the oil smoke will gradually flow toward the direction close to the second guide plate until it flows into the air inlet channel. In this way, the oil smoke can gather at the air inlet of the air inlet channel, so as to flow into the air inlet channel more smoothly, which can further improve the smoke extraction effect of the oil smoke, so as to further improve the user experience of the range hood.

[0015] By setting the third sub-plate and the fourth sub-plate, the oil smoke on the side of the third sub-plate close to the smoke inlet can flow along the third sub-plate and the fourth sub-plate toward the direction of the air inlet close to the air inlet channel. Since the other end of the fourth sub-plate is closer to the first guide plate than one end of the fourth sub-plate, this part of the oil smoke will gradually flow toward the direction close to the first guide plate until it flows into the air inlet channel. In this way, the oil smoke can be gathered at the air inlet of the air inlet channel, so as to flow into the air inlet channel more smoothly, which can further improve the smoke extraction effect of the oil smoke, so as to further improve the user experience of the range hood.

[0016] In some embodiments of the present application, one end of the first guide plate away from the fan cover extends to below the smoke inlet. And / or one end of the second guide plate away from the fan cover extends to below the smoke inlet.

[0017] Through the above-mentioned arrangement, when the oil smoke is sucked into the smoke collecting chamber from the smoke inlet, the arrangement of the above-mentioned first guide plate can reduce the amount of oil smoke flowing from under the first guide plate to the side of the first guide plate away from the second guide plate, thereby allowing more oil smoke to flow into the air inlet channel along the first guide plate and the second guide plate, so as to improve the guiding effect of the air guide plate assembly on the oil smoke.

[0018] The above-mentioned setting method of the second guide plate can reduce the amount of oil smoke flowing from the bottom of the second guide plate to the side of the second guide plate away from the first guide plate, so that more oil smoke can flow into the air inlet channel along the first guide plate and the second guide plate, so as to improve the guiding effect of the air guide plate assembly on the oil smoke.

[0019] In some embodiments of the present application, the smoke inlet includes a first inlet and a second inlet, and the first inlet and the second inlet are spaced apart along a first horizontal direction. The guide plate assembly also includes a first smoke isolation plate, which is connected to the front wall of the smoke hood and is located between the first inlet and the second inlet.

[0020] Through the above arrangement, during the operation of the range hood, the first smoke partition plate can separate part of the oil smoke entering the smoke collecting chamber from the first inlet and part of the oil smoke entering the smoke collecting chamber from the second inlet, thereby reducing the amount of oil smoke entering the smoke collecting chamber from the first inlet and the oil smoke entering the smoke collecting chamber from the second inlet intersecting in the smoke collecting chamber. In this way, part of the oil smoke between the first smoke partition plate and the first guide plate can flow into the air inlet channel more smoothly, and part of the oil smoke between the first smoke partition plate and the second guide plate can flow into the air inlet channel more smoothly, thereby further improving the guiding effect of the guide plate assembly on the oil smoke, so as to further improve the exhaust rate of the range hood.

[0021] In some embodiments of the present application, one end of the first smoke barrier plate close to the fan cover extends above the first inlet and the second inlet, and one end of the first smoke barrier plate away from the fan cover extends below the first inlet and the second inlet.

[0022] Through the above-mentioned arrangement, after the oil smoke enters the smoke collecting chamber from the first inlet and the second inlet, the arrangement of the above-mentioned first smoke barrier plate can reduce the amount of oil smoke between the first guide plate and the second guide plate that intersects above the first smoke barrier plate, and reduce the amount of oil smoke between the first guide plate and the second guide plate that intersects below the first smoke barrier plate. This can improve the separation effect of the first smoke barrier plate on the oil smoke entering the smoke collecting chamber from the first inlet and the oil smoke entering the smoke collecting chamber from the second inlet, thereby further improving the wind guiding effect of the guide plate assembly, so that the oil smoke in the smoke collecting chamber can enter the air inlet channel more smoothly.

[0023] In some embodiments of the present application, one end of the first smoke partition plate close to the rear wall of the smoke collecting hood is connected to the rear wall of the smoke collecting hood.

[0024] Through the above arrangement, there is no gap between the first smoke partition plate and the rear wall of the smoke hood. When the oil smoke enters between the first guide plate and the second guide plate, the oil smoke entering the smoke collecting chamber from the first inlet and the oil smoke entering the smoke collecting chamber from the second inlet will not intersect at the end of the first smoke partition plate close to the rear wall of the smoke collecting chamber. In this way, through the arrangement of the first smoke partition plate, the amount of oil smoke entering the smoke collecting chamber from the first inlet and the oil smoke entering the smoke collecting chamber from the second inlet intersecting in the smoke collecting chamber can be reduced, thereby further improving the guiding effect of the guide plate assembly on the oil smoke.

[0025] In some embodiments of the present application, the guide plate assembly further comprises a second smoke barrier plate, which is connected to the front wall of the smoke hood and is located between the first inlet and the second inlet. The first smoke barrier plate is connected to an edge of the first inlet away from the first guide plate. The second smoke barrier plate is connected to an edge of the second inlet away from the second guide plate.

[0026] Through the above-mentioned arrangement, the arrangement of the first smoke partition plate and the second smoke partition plate can reduce the distance between the first smoke partition plate and the first guide plate, thereby further reducing the diffusion of oil smoke in the smoke collecting chamber, and the distance between the second smoke partition plate and the second guide plate is also small, which can also reduce the diffusion of oil smoke in the smoke collecting chamber, so that the oil smoke can flow into the air inlet channel more smoothly along the guide plate assembly, thereby further improving the air suction effect of the range hood.

[0027] In some embodiments of the present application, the guide plate assembly also includes a third guide plate, which is located in the smoke collecting chamber, and the upper end of the third guide plate is connected to the side edge of the front wall surface of the air inlet of the air inlet channel close to the smoke collecting hood, and the lower end of the third guide plate is connected to the upper edge of the smoke inlet.

[0028] Through the above-mentioned arrangement, the third guide plate can reduce the amount of oil smoke between the first guide plate and the second guide plate that diffuses toward the top of the smoke inlet, thereby confining more oil smoke between the first guide plate and the second guide plate, so that more oil smoke can flow into the air inlet channel along the first guide plate and the second guide plate, thereby further improving the guiding effect of the guide plate assembly on the oil smoke.

[0029] In a second aspect of the present application, a range hood is provided, comprising a fan cover, a fan, a smoke collecting hood and a guide plate assembly. The fan cover is formed with an air inlet channel. The fan is arranged in the air inlet channel, and is used to discharge the oil smoke in the air inlet channel to the outside. The smoke collecting hood is formed with a smoke collecting chamber and a smoke inlet connected to the smoke collecting chamber, and the smoke inlet is connected to the outside of the range hood. The fan cover is connected to the top of the smoke collecting hood, and the air inlet channel is connected to the smoke collecting chamber. The guide plate assembly is arranged in the smoke collecting chamber. The guide plate assembly comprises a first guide plate and a second guide plate. The first guide plate, the first guide plate is arranged at one side edge of the smoke inlet in the first horizontal direction, and the first horizontal direction is parallel to the plane where the smoke inlet is located. The first guide plate is connected to the air inlet of the air inlet channel, and the smoke inlet is opened on the front wall of the smoke collecting hood. The second guide plate, the second guide plate is arranged at the other side edge of the smoke inlet in the first horizontal direction. The second guide plate is connected to the air inlet of the air inlet channel.

[0030] The range hood provided in the second aspect of the present application can achieve the same beneficial effects as the above-mentioned technical solution, so it will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, the use of words such as "exemplarily" or "for example" is intended to present related concepts in a specific way.

[0058] As a household appliance that absorbs oil droplets and removes oil fumes, the range hood can purify the air in the kitchen and improve the user's cooking experience.

[0059] Based on this, the present application provides a range hood, such as Figure 1 , Figure 2 As shown, the range hood 10 includes a fan cover 1 , and the fan cover 1 is formed with an air inlet channel 11 .

[0060] like Figure 1 , Figure 2 As shown, the range hood 10 further includes a smoke collecting hood 2, which is formed with a smoke collecting cavity 21 and a smoke inlet 22 connected to the smoke collecting cavity 21, and the smoke inlet 22 is connected to the outside of the range hood 10. The fan cover 1 is connected to the top of the smoke collecting hood 2, and the air inlet channel 11 is connected to the smoke collecting cavity 21.

[0061] It can be understood that the fan cover 1 is connected to the top of the smoke collecting hood 2, and when the oil smoke flows from the smoke collecting hood 2 into the air inlet channel 11, it will flow into the air inlet channel 11 upward along the vertical direction.

[0062] Specifically, Figure 3 As shown, along the first horizontal direction ( Figure 3 The first horizontal direction is parallel to the plane where the smoke inlet 22 is located. Figure 2 As shown, the range hood 10 further includes a fan 3, which is disposed in the air inlet channel 11 and is used to discharge the oil smoke in the air inlet channel 11 to the outside. Specifically, during the operation of the fan 3, the oil smoke in the kitchen can be sucked into the smoke collecting chamber 21, and then sucked into the air inlet channel 11, and discharged to the outside under the action of the fan 3.

[0063] A filter is provided at the air inlet of the air inlet channel 11 , and the oil droplets in the oil smoke will be filtered by the filter and condensed in the smoke collecting chamber 21 .

[0064] On this basis, the range hood 10 further includes an oil receiving pan and an oil cup, both of which are arranged in the smoke collecting chamber 21. The oil receiving pan is used to collect oil droplets in the smoke collecting chamber 21, and an oil receiving hole is provided on the oil receiving pan. The oil cup is arranged below the oil pan, and the mouth of the oil cup is located directly below the oil receiving hole.

[0065] In this way, the oil droplets in the smoke collecting chamber 21 can gather on the oil receiving pan and then flow into the oil cup from the oil receiving hole to collect the oil droplets in the smoke collecting chamber 21. The user can remove the oil droplets in the smoke collecting chamber 21 by cleaning the oil cup.

[0066] Among them, Figure 4 As shown, the smoke inlet 22 is arranged on the front wall surface 24 of the smoke collecting hood, that is, the range hood 10 provided in the present application is a side-suction range hood.

[0067] In some examples, such as Figure 4 As shown, the front wall surface 24 of the smoke collecting hood is recessed toward the rear wall surface 25 of the smoke collecting hood to form a groove 23, and the smoke inlet 22 is opened on the bottom wall of the groove 23. In this way, when the range hood 10 is working, the oil smoke can be covered in the groove 23, thereby improving the smoke extraction effect of the range hood 10.

[0068] It should be noted that the front wall surface 24 of the smoke hood refers to a wall surface of the smoke hood 2 close to the indoor side in the horizontal direction, and the rear wall surface 25 of the smoke hood refers to a wall surface of the smoke hood 2 close to the outdoor side in the horizontal direction.

[0069] In some embodiments, Figure 5 , Figure 6 As shown, the fan 3 has a first air inlet side 31 and a second air inlet side 32 arranged opposite to each other, the first air inlet side 31 is located on the side of the fan 3 close to the rear wall surface 13 of the fan cover, and the second air inlet side 32 is located on the side of the fan 3 close to the front wall surface 12 of the fan cover. That is, the fan 3 is a double-inlet fan 3.

[0070] In some examples, such as Figure 5 As shown, the fan 3 further includes a body 33 and an air outlet duct 34. The body 33 is formed with a first air inlet side 31 and a second air inlet side 32. The air outlet duct 34 is connected to the upper part of the body 33 and communicates with the outside.

[0071] In the related art, the length and width of the smoke hood 2 usually match the stove, resulting in a larger length of the smoke hood 2, and thus the space inside the smoke hood 2 is also relatively large in the length direction, while the fan hood 1 usually only needs to adapt to the fan 3, and the size of the fan hood 1 in the length direction of the smoke hood 2 is smaller than that of the smoke hood 2.

[0072] In the above-mentioned arrangement of the range hood 10, after the oil smoke enters the smoke collecting hood 2, it will diffuse inside the smoke collecting hood 2 and then enter the fan cover 1. This will cause the oil smoke to fail to quickly enter the fan cover 1 and thus fail to be quickly discharged outdoors, which will affect the smoke extraction effect of the range hood 10 and further affect the user experience of the range hood 10.

[0073] In order to improve the user's experience of using the range hood 10, in some embodiments, Figure 2 , Figure 7 As shown, the range hood 10 further includes a guide plate assembly 4 , which is disposed in the smoke collecting chamber 21 .

[0074] Specifically, Figure 3 , Figure 7 As shown, the guide plate assembly 4 includes a first guide plate 41 and a second guide plate 42 .

[0075] The first guide plate 41 is disposed at one side edge of the smoke inlet 22 in the first horizontal direction. The first guide plate 41 is connected to the air inlet of the air inlet channel 11 .

[0076] Specifically, in some embodiments, Figure 3 , Figure 4 As shown, the first guide plate 41 is also connected to the front wall surface 24 of the smoke collecting hood.

[0077] like Figure 3 , Figure 7 As shown, the second guide plate 42 is disposed at the other side edge of the smoke inlet 22 in the first horizontal direction. The second guide plate 42 is connected to the air inlet of the air inlet channel 11 .

[0078] Specifically, in some embodiments, Figure 3 As shown, the second guide plate 42 is also connected to the front wall surface 24 of the smoke collecting hood.

[0079] Through the above arrangement, since the first guide plate 41 and the second guide plate 42 are respectively arranged at the two opposite edges of the smoke inlet 22 in the first horizontal direction, after the oil smoke is sucked into the smoke collecting chamber 21, it will first flow between the first guide plate 41 and the second guide plate 42.

[0080] Since the first guide plate 41 and the second guide plate 42 are both connected to the air inlet of the air inlet channel 11 , most of the oil smoke will flow along the first guide plate 41 and the second guide plate 42 under the action of the fan 3 , and then enter the air inlet channel 11 .

[0081] In this way, under the guidance of the first guide plate 41 and the second guide plate 42, most of the oil smoke will not diffuse in the smoke collecting chamber 21, which can increase the rate at which the oil smoke in the smoke collecting chamber 21 enters the air inlet channel 11, thereby improving the smoke extraction effect of the range hood 10 and improving the user experience of the range hood 10.

[0082] In addition, when the oil smoke flows from the smoke collecting chamber 21 to the air inlet channel 11, compared with the oil smoke flowing in the entire smoke collecting chamber 21, the oil smoke can flow into the air inlet channel 11 more smoothly when it flows between the first guide plate 41 and the second guide plate 42. This can reduce the friction between the oil smoke and the air during the flow, thereby reducing the noise generated during the operation of the range hood 10, and can also improve the user experience of the range hood 10.

[0083] In some embodiments, Figure 8 As shown, one end of the first guide plate 41 close to the rear wall 25 of the smoke hood is connected to the rear wall 25 of the smoke hood. Through the above arrangement, there is no gap between the first guide plate 41 and the rear wall 25 of the smoke hood. When the oil smoke enters between the first guide plate 41 and the second guide plate 42, the oil smoke will not flow from the end of the first guide plate 41 close to the rear wall 25 of the smoke hood to the side of the first guide plate 41 away from the second guide plate 42.

[0084] In this way, the first guide plate 41 and the second guide plate 42 can confine more oil smoke between the first guide plate 41 and the second guide plate 42, so that more oil smoke can flow into the air inlet channel 11 along the first guide plate 41 and the second guide plate 42 to improve the guiding effect of the guide plate assembly 4 on the oil smoke.

[0085] In some embodiments, Figure 8 As shown, one end of the second guide plate 42 close to the rear wall surface 25 of the smoke collecting hood is connected to the rear wall surface 25 of the smoke collecting hood.

[0086] Through the above arrangement, there is no gap between the second guide plate 42 and the rear wall 25 of the smoke hood. When the oil smoke enters between the first guide plate 41 and the second guide plate 42, the oil smoke will not flow from the end of the second guide plate 42 close to the rear wall 25 of the smoke hood to the side of the second guide plate 42 away from the first guide plate 41.

[0087] In this way, the first guide plate 41 and the second guide plate 42 can confine more oil smoke between the first guide plate 41 and the second guide plate 42, so that more oil smoke can flow into the air inlet channel 11 along the first guide plate 41 and the second guide plate 42 to improve the guiding effect of the guide plate assembly 4 on the oil smoke.

[0088] In some examples, a first bent edge is formed at one end of the first guide plate 41 near the rear wall 25 of the smoke hood and at one end of the second guide plate 42 near the rear wall 25 of the smoke hood, and a screw hole is provided on the first bent edge. The range hood 10 also includes screws, which pass through the screw holes and are connected to the rear wall 25 of the smoke hood, thereby realizing the connection between the first guide plate 41 and the rear wall 25 of the smoke hood and the connection between the second guide plate 42 and the rear wall 25 of the smoke hood.

[0089] In some examples, such as Fig. 9 , Fig.10 As shown, the fan cover 1 partially extends into the smoke collecting chamber 21, and the part of the fan cover 1 extending into the smoke collecting chamber 21 forms the air inlet of the air inlet channel 11. The first guide plate 41 and the second guide plate 42 are both connected to the outer wall surface of the air inlet of the air inlet channel 11.

[0090] Exemplarily, the first guide plate 41 may be a flat plate.

[0091] For example, Fig.11 As shown, the first guide plate 41 includes a first sub-plate 411 and a second sub-plate 412. The first sub-plate 411 is located at one side edge of the smoke inlet 22 in the first horizontal direction. One end of the second sub-plate 412 is connected to one end of the first sub-plate 411 close to the fan cover 1, and the other end of the second sub-plate 412 is connected to the air inlet of the air inlet channel 11, and the other end of the second sub-plate 412 is closer to the second guide plate 42 than one end of the second sub-plate 412.

[0092] Exemplarily, the thickness direction of the first sub-plate 411 may be consistent with the first horizontal direction, or may not be consistent with the first horizontal direction.

[0093] Exemplarily, the thickness direction of the second sub-plate 412 may be parallel to or may not be parallel to the plane where the smoke inlet 22 is located.

[0094] In some examples, one end of the first sub-plate 411 close to the rear wall 25 of the fume hood is connected to the rear wall 25 of the fume hood. One end of the second sub-plate 412 close to the rear wall 25 of the fume hood is connected to the rear wall 25 of the fume hood.

[0095] Through the above arrangement, after entering the smoke collecting chamber 21 , the oil smoke will first flow between the first sub-plate 411 and the second guide plate 42 , and then flow toward the air inlet of the air inlet channel 11 .

[0096] Among them, the oil smoke located on the side of the first sub-plate 411 close to the smoke inlet 22 can flow along the first sub-plate 411 toward the air inlet close to the air inlet channel 11 and contact the second sub-plate 412. At this time, this part of the oil smoke can continue to flow along the second sub-plate 412 toward the air inlet close to the air inlet channel 11. Since the other end of the second sub-plate 412 is closer to the second guide plate 42 than one end of the second sub-plate 412, this part of the oil smoke will gradually flow in the direction close to the second guide plate 42 until it flows into the air inlet channel 11.

[0097] In this way, through the arrangement of the first sub-plate 411 and the second sub-plate 412, part of the oil smoke can be gathered at the air inlet of the air inlet channel 11 along the first sub-plate 411 and the second sub-plate 41, so as to flow into the air inlet channel 11 more smoothly, which can further improve the smoke extraction effect of the oil smoke, so as to further improve the user experience of the range hood 10.

[0098] It can be understood that the connection between the second sub-plate 412 and the first sub-plate 411 means that the edge of one end of the second sub-plate 412 is connected to the edge of one end of the first sub-plate 411 to ensure the guiding effect of the first sub-plate 411 and the second sub-plate 412 on the oil smoke.

[0099] Exemplarily, the second guide plate 42 may be a flat plate.

[0100] For example, Fig.11 As shown, the second guide plate 42 includes a third sub-plate 421 and a fourth sub-plate 422. The third sub-plate 421 is located at one side edge of the smoke inlet 22 in the first horizontal direction. One end of the fourth sub-plate 422 is connected to one end of the first sub-plate 411 close to the fan cover 1, and the other end of the fourth sub-plate 422 is connected to the air inlet of the air inlet channel 11, and the other end of the fourth sub-plate 422 is closer to the first guide plate 41 than one end of the fourth sub-plate 422.

[0101] Exemplarily, the thickness direction of the third sub-plate 421 may be consistent with the first horizontal direction, or may not be consistent with the first horizontal direction.

[0102] Exemplarily, the thickness direction of the fourth sub-plate 422 may be parallel to or may not be parallel to the plane where the smoke inlet 22 is located.

[0103] In some examples, one end of the third sub-plate 421 close to the rear wall 25 of the smoke hood is connected to the rear wall 25 of the smoke hood. One end of the fourth sub-plate 422 close to the rear wall 25 of the smoke hood is connected to the rear wall 25 of the smoke hood.

[0104] Through the above arrangement, after entering the smoke collecting chamber 21 , the oil smoke will first flow between the third sub-plate 421 and the first guide plate 41 , and then flow toward the air inlet of the air inlet channel 11 .

[0105] Among them, the oil smoke located on the side of the third sub-plate 421 close to the smoke inlet 22 can flow along the third sub-plate 421 toward the air inlet close to the air inlet channel 11 and contact the fourth sub-plate 422. At this time, this part of the oil smoke can continue to flow along the fourth sub-plate 422 toward the air inlet close to the air inlet channel 11. Since the other end of the fourth sub-plate 422 is closer to the first guide plate 41 than one end of the fourth sub-plate 422, this part of the oil smoke will gradually flow in the direction close to the first guide plate 41 until it flows into the air inlet channel 11.

[0106] In this way, through the setting of the third sub-plate 421 and the fourth sub-plate 422, part of the oil smoke can be gathered at the air inlet of the air inlet channel 11 along the third sub-plate 421 and the fourth sub-plate 422, so as to flow into the air inlet channel 11 more smoothly, which can further improve the smoke extraction effect of the oil smoke, so as to further improve the user experience of the range hood 10.

[0107] It can be understood that the connection between the fourth sub-plate 422 and the third sub-plate 421 means that the edge of one end of the fourth sub-plate 422 is connected to the edge of one end of the third sub-plate 421 to ensure the guiding effect of the third sub-plate 421 and the fourth sub-plate 422 on the oil smoke.

[0108] In some examples, one end of the first sub-plate 411 away from the air inlet of the air inlet channel 11 and one end of the third sub-plate 421 away from the air inlet of the air inlet channel 11 are both located directly above the oil receiving pan.

[0109] In this way, after being filtered by the filter at the air inlet of the air inlet channel 11, the oil droplets in the oil smoke can drip onto the oil receiving pan along the second sub-plate 412 and the first sub-plate 411, and can also drip onto the oil receiving pan along the fourth sub-plate 422 and the third sub-plate 421, thereby converging on the oil receiving pan and finally being collected in the oil cup.

[0110] On this basis, in some embodiments, such as Fig.12 , Fig.13 As shown, one end of the first guide plate 41 away from the fan cover 1 extends to below the smoke inlet 22 .

[0111] It can be understood that the lower side of the smoke inlet 22 refers to the lower side of the lowest point of the lower edge of the smoke inlet 22 .

[0112] In this way, when the oil smoke is sucked into the smoke collecting chamber 21 from the smoke inlet 22, the arrangement of the first guide plate 41 can reduce the amount of oil smoke flowing from below the first guide plate 41 to the side of the first guide plate 41 away from the second guide plate 42, thereby allowing more oil smoke to flow into the air inlet channel 11 along the first guide plate 41 and the second guide plate 42, so as to improve the guiding effect of the air guide plate assembly 4 on the oil smoke.

[0113] On this basis, in some embodiments, such as Fig.12 , Fig.13 As shown, one end of the second guide plate 42 away from the fan cover 1 extends to below the smoke inlet 22 .

[0114] In this way, when the oil smoke is sucked into the smoke collecting chamber 21 from the smoke inlet 22, the arrangement of the second guide plate 42 can reduce the amount of oil smoke flowing from under the second guide plate 42 to the side of the second guide plate 42 away from the first guide plate 41, thereby allowing more oil smoke to flow into the air inlet channel 11 along the first guide plate 41 and the second guide plate 42, so as to improve the guiding effect of the air guide plate assembly 4 on the oil smoke.

[0115] In some embodiments, Fig.14 As shown, the smoke inlet 22 includes a first inlet 221 and a second inlet 222, and the first inlet 221 and the second inlet 222 are spaced apart along a first horizontal direction.

[0116] The guide plate assembly 4 further includes a first smoke isolation plate 43 . The first smoke isolation plate 43 is connected to the front wall surface 24 of the smoke collecting hood and is located between the first inlet 221 and the second inlet 222 .

[0117] Exemplarily, the thickness direction of the first smoke isolation plate 43 may be consistent with the first horizontal direction, or may not be consistent with the first horizontal direction.

[0118] It can be understood that the range hood 10 can simultaneously remove indoor oil fumes through the first inlet 221 and the second inlet 222, and the first inlet 221 and the second inlet 222 can be respectively set to correspond to an oil fume source (such as a stove, a burner, etc.), so as to more effectively remove indoor oil fumes.

[0119] Through the above-mentioned arrangement, during the operation of the range hood 10, the first smoke partition plate 43 can separate part of the oil smoke entering the smoke collecting chamber 21 from the first inlet 221 and part of the oil smoke entering the smoke collecting chamber 21 from the second inlet 222, thereby reducing the amount of oil smoke entering the smoke collecting chamber 21 from the first inlet 221 and the oil smoke entering the smoke collecting chamber 21 from the second inlet 222 intersecting in the smoke collecting chamber 21.

[0120] In this way, part of the oil smoke between the first smoke partition plate 43 and the first guide plate 41 can flow into the air inlet channel 11 more smoothly, and part of the oil smoke between the first smoke partition plate 43 and the second guide plate 42 can flow into the air inlet channel 11 more smoothly, thereby further improving the guiding effect of the guide plate assembly 4 on the oil smoke, so as to further improve the smoke exhaust rate of the range hood 10.

[0121] In addition, when the concentrations of part of the oil fume entering the smoke collecting chamber 21 from the first inlet 221 and part of the oil fume entering the smoke collecting chamber 21 from the second inlet 222 are different (for example, the user uses different kitchen utensils and stoves when cooking, more oil fume is generated at the first inlet 221, and less oil fume is generated at the second inlet 222), through the provision of the first smoke shielding plate 43, the oil fume at the first inlet 221 and the oil fume at the second inlet 222 can flow on both sides of the first smoke shielding plate 43 respectively, thereby reducing the amount of high-concentration oil fume diffusing to the location where low-concentration oil fume is located, so that both high-concentration oil fume and low-concentration oil fume can flow into the air inlet channel 11 more smoothly, thereby improving the smoking effect when the range hood 10 inhales oil fumes of different concentrations through the first inlet 221 and the second inlet 222 at the same time.

[0122] On this basis, in some embodiments, such as Fig.15 As shown, one end of the first smoke isolation plate 43 close to the fan cover 1 extends above the first inlet 221 and the second inlet 222. One end of the first smoke isolation plate 43 away from the fan cover 1 extends below the first inlet 221 and the second inlet 222.

[0123] Exemplarily, the first inlet 221 may be located between the first smoke isolation plate 43 and the first guide plate 41 , or between the first smoke isolation plate 43 and the second guide plate 42 .

[0124] Through the above-mentioned arrangement, after the oil smoke enters the smoke collecting chamber 21 from the first inlet 221 and the second inlet 222, the arrangement of the above-mentioned first smoke barrier plate 43 can reduce the amount of oil smoke between the first guide plate 41 and the second guide plate 42 intersecting above the first smoke barrier plate 43, and reduce the amount of oil smoke between the first guide plate 41 and the second guide plate 42 intersecting below the first smoke barrier plate 43. In this way, the separation effect of the first smoke barrier plate 43 on the oil smoke entering the smoke collecting chamber 21 from the first inlet 221 and the oil smoke entering the smoke collecting chamber 21 from the second inlet 222 can be improved, thereby further improving the wind guiding effect of the guide plate assembly 4, so that the oil smoke in the smoke collecting chamber 21 can enter the air inlet channel 11 more smoothly.

[0125] Exemplarily, one end of the first smoke partition plate 43 close to the rear wall of the smoke collecting hood 2 may be spaced apart from the rear wall 25 of the smoke collecting hood.

[0126] For example, Fig.16 As shown, along the second horizontal direction, one end of the first smoke partition plate 43 close to the rear wall surface 25 of the smoke collecting hood is connected to the rear wall surface 25 of the smoke collecting hood.

[0127] Through the above arrangement, there is no gap between the first smoke partition plate 43 and the rear wall surface 25 of the smoke collecting hood. When the oil smoke enters between the first guide plate 41 and the second guide plate 42, the oil smoke entering the smoke collecting chamber 21 from the first inlet 221 and the oil smoke entering the smoke collecting chamber 21 from the second inlet 222 will not intersect at the end of the first smoke partition plate 43 close to the rear wall surface 25 of the smoke collecting hood.

[0128] In this way, by setting the first smoke barrier plate 43, the amount of oil smoke entering the smoke collecting chamber 21 from the first inlet 221 and the oil smoke entering the smoke collecting chamber 21 from the second inlet 222 can be reduced, thereby further improving the guiding effect of the guide plate assembly 4 on the oil smoke.

[0129] Based on the above, in some embodiments, such as Fig.16 , Fig.17 As shown, the guide plate assembly 4 further includes a second smoke isolation plate 44 . The second smoke isolation plate 44 is connected to the front wall surface 24 of the smoke collecting hood and is located between the first inlet 221 and the second inlet 222 .

[0130] The first smoke isolation plate 43 is connected to an edge of the first inlet 221 away from the first guide plate 41 . The second smoke isolation plate 44 is connected to an edge of the second inlet 222 away from the second guide plate 42 .

[0131] It can be understood that, in the above arrangement, the first inlet 221 is located between the first guide plate 41 and the first smoke isolation plate 43 , and the second inlet 222 is located between the second guide plate 42 and the second smoke isolation plate 44 .

[0132] Exemplarily, the thickness direction of the second smoke isolation plate 44 may be consistent with the first horizontal direction, or may not be consistent with the first horizontal direction.

[0133] Exemplarily, the thickness direction of the second smoke isolation plate 44 may be consistent with the thickness direction of the first smoke isolation plate 43 , or may be inconsistent with the thickness direction of the first smoke isolation plate 43 .

[0134] Through the above-mentioned arrangement, since the first smoke screen 43 is connected to the side edge of the first inlet 221 close to the second inlet 222, when the oil smoke enters the smoke hood 2 from the first inlet 221, the oil smoke can directly contact the first guide plate 41 and the first smoke screen 43, and will not flow to the two sides of the first inlet 221 in the first horizontal direction, and will flow along the first guide plate 41 and the first smoke screen 43 toward the direction close to the air inlet channel 11.

[0135] Since the second smoke shielding plate 44 is connected to the side edge of the second inlet 222 close to the first inlet 221, when the oil smoke enters the smoke collecting hood 2 from the second inlet 222, the oil smoke can directly contact the second guide plate 42 and the second smoke shielding plate 44, and will not flow to the two sides of the second inlet 222 in the first horizontal direction, and will flow along the second guide plate 42 and the second smoke shielding plate 44 toward the direction close to the air inlet channel 11.

[0136] In this way, by setting the first smoke partition plate 43 and the second smoke partition plate 44, the distance between the first smoke partition plate 43 and the first guide plate 41 can be reduced, thereby further reducing the diffusion of oil smoke in the smoke collecting chamber 21, and the distance between the second smoke partition plate 44 and the second guide plate 42 is also small, which can also reduce the diffusion of oil smoke in the smoke collecting chamber 21, so that the oil smoke can flow into the air inlet channel 11 more smoothly along the guide plate assembly 4, thereby further improving the suction effect of the range hood 10.

[0137] In some examples, the thickness direction of the first smoke isolation board 43 and the thickness direction of the second smoke isolation board 44 are both consistent with the first horizontal direction.

[0138] In some examples, such as Fig.18 As shown, the guide plate assembly 4 also includes a fixing plate 45, and the first smoke isolation plate 43 and the second smoke isolation plate 44 are connected to the fixing plate 45. The thickness direction of the fixing plate 45 is consistent with the thickness direction of the front wall surface 24 of the smoke hood, and is connected to the front wall surface 24 of the smoke hood.

[0139] Exemplarily, the first smoke isolation plate 43 and the fixing plate 45 may be separate structures or integrally formed structures.

[0140] Exemplarily, the second smoke isolation plate 44 and the fixing plate 45 may be separate structures or integrally formed structures.

[0141] In this way, when installing the first smoke barrier plate 43 and the second smoke barrier plate 44, the first smoke barrier plate 43 and the second smoke barrier plate 44 can be first installed on the fixing plate 45 outside the smoke collecting chamber 21, and then the fixing plate 45 can be connected to the smoke collecting chamber 21. This can simplify the operation process in the smoke collecting chamber 21 during the installation of the first smoke barrier plate 43 and the second smoke barrier plate 44, and there is a larger operating space outside the smoke collecting chamber 21, thereby facilitating the installation of the first smoke barrier plate 43 and the second smoke barrier plate 44.

[0142] In some embodiments, Fig.19 , Fig. 20As shown, the guide plate assembly 4 also includes a third guide plate 46, which is located in the smoke collecting chamber 21, and the upper end of the third guide plate 46 is connected to the side edge of the front wall surface 24 of the smoke collecting hood near the air inlet of the air inlet channel 11, and the lower end of the third guide plate 46 is connected to the upper edge of the smoke inlet port 22.

[0143] Through the above-mentioned arrangement, the third guide plate 46 can reduce the amount of oil smoke between the first guide plate 41 and the second guide plate 42 that diffuses toward the top of the smoke inlet 22, thereby confining more oil smoke between the first guide plate 41 and the second guide plate 42, so that more oil smoke can flow into the air inlet channel 11 along the first guide plate 41 and the second guide plate 42, so as to further improve the guiding effect of the guide plate assembly 4 on the oil smoke.

[0144] In some examples, a thickness direction of the third guide plate 46 is perpendicular to the first horizontal direction.

[0145] In some examples, such as Fig.18 , Fig.19 As shown, the third guide plate 46 is connected to the air inlet of the air inlet channel 11. One end of the third guide plate 46 in the first horizontal direction is connected to the first guide plate 41, and the other end of the third guide plate 46 in the first horizontal direction is connected to the second guide plate 42.

[0146] For example, the thickness direction of the third guide plate 46 may be consistent with the thickness direction of the front wall surface 24 of the smoke collecting hood, or may not be consistent with the thickness direction of the front wall surface 24 of the smoke collecting hood.

[0147] Through the above-mentioned arrangement, the third guide plate 46 can block the first guide plate 41 and the second guide plate 42, and open on one side of the front wall surface 24 above the smoke inlet 22 and close to the smoke collecting hood, so that more oil smoke can be restricted to the first guide plate 41 and the second guide plate 42, thereby reducing the amount of oil smoke diffusion in the smoke collecting chamber 21, so as to further improve the guiding effect of the guide plate assembly 4 on the oil smoke.

[0148] In some examples, when the front wall surface 24 of the smoke collecting hood forms a groove 23 , the third guide plate 46 is connected to the bottom wall of the groove 23 .

[0149] In some examples, the front wall surface 24 of the fume collecting hood is inclined toward the oil fume source so as to facilitate the range hood 10 to inhale the oil fume.

[0150] On this basis, if Fig.21As shown, the first inlet 221 and the second inlet 222 are both in a trapezoidal shape, and one end of the third guide plate 46 close to the first inlet 221 is bent toward the side close to the smoke collecting chamber 21 to form a second bent edge 461. One end of the third guide plate 46 close to the second inlet 222 is bent toward the side close to the smoke collecting chamber 21 to form a third bent edge 462. The thickness direction of the second bent edge 461 is parallel to the plane where the first inlet 221 is located. The thickness direction of the third bent edge 462 is parallel to the plane where the second inlet 222 is located.

[0151] The second bent edge 461 is connected to the third bent edge 462, and one end of the second bent edge 461 away from the third bent edge 462 is spaced apart from the first guide plate 41 and is located on a side of the first inlet 221 close to the first guide plate 41. One end of the third bent edge 462 away from the second bent edge 461 is spaced apart from the second guide plate 42 and is located on a side of the second inlet 222 close to the second guide plate 42.

[0152] It can be understood that since the shapes of the first inlet 221 and the second inlet 222 are both trapezoidal, the end of the second bent edge 461 away from the first guide plate 41 is located above the end of the second bent edge 461 close to the first guide plate 41, and the section of the third bent edge 462 away from the second guide plate 42 is located above the end of the third bent edge 462 close to the second guide plate 42.

[0153] Through the above-mentioned arrangement, when the oil droplets adhere to the third guide plate 46, the oil droplets will flow downward until they come into contact with the second bent edge 461 or the third bent edge 462. Since the thickness direction of the second bent edge 461 is parallel to the plane where the first inlet 221 is located, the thickness direction of the third bent edge 462 is parallel to the plane where the second inlet 222 is located, and the front wall surface 24 of the smoke hood is inclined toward the oil smoke source, the oil droplets will gather between the second bent edge 461 and the third guide plate 46, and between the third bent edge 462 and the third guide plate 46.

[0154] In this way, the oil droplets can flow along the second bent edge 461 to the side of the first inlet 221 close to the first guide plate 41, and can flow along the third bent edge 462 to the side of the second inlet 222 close to the second guide plate 42, and then drip into the oil receiving pan. In this way, the oil droplets can be prevented from dripping out of the range hood 10 from the first inlet 221 or the second inlet 222, thereby improving the user experience of the range hood 10.

[0155] On this basis, the upper edge of the first inlet 221 is bent toward the side close to the smoke collecting chamber 21 to form a fourth bent edge 223 , and the upper edge of the second inlet 222 is bent toward the side close to the smoke collecting chamber 21 to form a fifth bent edge 224 .

[0156] The fourth bent edge 223 is located below the second bent edge 461, and the thickness direction of the fourth bent edge 223 is consistent with the thickness direction of the second bent edge 461. One end of the fourth bent edge 223 close to the rear wall 25 of the smoke hood is located on the side of the second bent edge 461 close to the rear wall 25 of the smoke hood.

[0157] The fifth bending edge 224 is located below the third bending edge 462, and the thickness direction of the fifth bending edge 224 is consistent with the thickness direction of the third bending edge 462. One end of the fifth bending edge 224 close to the rear wall 25 of the smoke hood is located on one side of the third bending edge 462 close to the rear wall 25 of the smoke hood.

[0158] In some examples, a peripheral edge of the first inlet 221 is bent toward a side close to the smoke collecting chamber 21 to form a fourth bent edge 223 .

[0159] In some examples, a peripheral edge of the second inlet 222 is bent toward a side close to the smoke collecting chamber 21 to form a fifth bent edge 224 .

[0160] By setting the second bent edge 461 and the third bent edge 462, after the oil smoke enters the smoke collecting chamber 21 from the first inlet 221 or the second inlet 222, it can flow directly to between the first guide plate 41 and the second guide plate 42 under the guidance of the fourth bent edge 223 and the fifth bent edge 224, and will not be blocked by the second bent edge 461 and the third bent edge 462 when flowing upward, thereby ensuring the wind guiding effect of the guide plate assembly 4 on the oil smoke.
