Description

Technical Field

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

[0002] The range hood usually includes a smoke collecting hood and a fan hood. The fan hood is connected to the top of the smoke collecting hood. The smoke collecting hood forms a smoke collecting cavity. The fan hood forms a fan cavity. A fan is arranged in the fan cavity. The fan cavity is connected to the smoke collecting cavity. The fan can draw the indoor smoke into the smoke collecting cavity and discharge it to the outside through the fan cavity.

[0003] In the related art, in order to improve the efficiency of the fan in extracting oil smoke, air inlets are formed on the front and rear sides of the fan, and in order to reasonably utilize the space, the smoke collection hood is located below the rear air inlet of the fan.

[0004] In this way, after the oil smoke enters the smoke collecting chamber, it can smoothly enter the rear air inlet of the fan. However, when the oil smoke enters the front air inlet of the fan, it needs to change its flow direction, which will encounter greater resistance, resulting in a slower flow rate of this part of the oil smoke, affecting the smoke exhaust rate of the range hood, and thus affecting the user's 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 a first aspect of the present application, a range hood is provided, comprising a smoke collecting hood, a fan cover and a fan. 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 comprises a bottom plate and a surrounding plate, the surrounding plate is connected to the top of the bottom plate and surrounds the bottom plate so that the bottom plate and the surrounding plate form a ventilation chamber with an opening at the upper end. The fan is arranged in the ventilation chamber and connected to the fan cover, and the fan is used to discharge the oil smoke in the ventilation chamber to the outside. A first air inlet is provided on one side of the fan close to the rear wall of the fan cover, and a second air inlet is provided on one side of the fan close to the front wall of the fan cover.

[0007] The bottom plate includes a first connecting plate and a second connecting plate. The first connecting plate is located in the smoke collecting chamber and connected to the enclosure. The first connecting plate is located below the first air inlet, and a third air inlet is provided on the first connecting plate. The second connecting plate is connected to the enclosure. The second connecting plate is connected to a side of the first connecting plate close to the second air inlet. The second connecting plate is away from one end of the first connecting plate and is located above one end of the second connecting plate close to the first connecting plate.

[0008] Through the above-mentioned arrangement, under the action of the fan, after the oil smoke enters the ventilation chamber from the third air inlet, part of the oil smoke can directly flow into the first air inlet along the gap between the fan and the rear wall of the fan cover, and another part of the oil smoke will enter the gap between the fan and the front wall of the fan cover along the gap between the fan and the second connecting plate, and then flow into the second air inlet, thereby being discharged outdoors by the fan.

[0009] In the process of oil smoke flowing between the fan and the second connecting plate, since the end of the second connecting plate away from the first connecting plate is located above the end of the second connecting plate close to the first connecting plate, the oil smoke will gradually flow toward the fan and gather together until it contacts the front wall of the fan cover. At this time, the oil smoke will continue to flow upward along the front wall of the fan cover and finally flow into the second air inlet.

[0010] In this way, compared with the oil smoke flowing horizontally between the fan and the second connecting plate, the flow direction of the oil smoke only needs to change a smaller angle when the oil smoke flows from between the fan and the second connecting plate to between the fan and the front wall of the fan cover, and the oil smoke changes direction more gradually and smoothly. This can reduce the resistance encountered by the oil smoke in the process of flowing to the second air inlet, so that the oil smoke can flow more smoothly in the ventilation cavity, thereby speeding up the flow rate of the oil smoke, thereby speeding up the exhaust rate of the range hood and improving the user experience of the range hood.

[0011] In some embodiments of the present application, the first connecting plate includes a first plate segment and a second plate segment. The first plate segment is located in the smoke collecting chamber and connected to the enclosure, and the first plate segment is provided with a third air inlet. The second plate segment is connected between the first plate segment and the second connecting plate, and one end of the second plate segment connected to the first plate segment is located below one end of the second plate segment connected to the second connecting plate, and is located on one side of the second plate segment connected to the second connecting plate close to the rear wall of the smoke collecting hood.

[0012] Through the above-mentioned arrangement, when the oil smoke flows along the second plate section to the gap between the fan and the second connecting plate, the oil smoke will flow in the direction close to the second connecting plate. Compared with the vertical arrangement of the second plate section, the oil smoke can enter the gap between the fan and the second connecting plate more smoothly, and then enter the second air inlet, which can further accelerate the flow rate of the oil smoke, thereby further accelerating the exhaust rate of the range hood and improving the user experience of the range hood.

[0013] In some embodiments of the present application, the front wall of the smoke collecting hood is in contact with and parallel to the second plate segment, and the smoke inlet is opened on the front wall of the smoke collecting hood.

[0014] Through the above-mentioned arrangement, after entering the smoke collecting chamber, the oil smoke can gradually flow along the front wall of the smoke collecting chamber towards the direction close to the third air inlet. Since the front wall of the smoke collecting hood is parallel to the second plate section, after entering the ventilation chamber, the oil smoke does not need to change its flow direction and can continue to flow along the second plate section. In this way, the oil smoke can flow more smoothly in the ventilation chamber, thereby further accelerating the smoke exhaust rate of the range hood.

[0015] In some embodiments of the present application, the range hood further comprises a smoke collecting plate, which is arranged in the ventilation cavity and located on a side of the first air inlet away from the second air inlet. One end of the smoke collecting plate is connected to the upper edge of the first air inlet, and the other end of the smoke collecting plate is connected to the enclosure.

[0016] Through the above-mentioned arrangement, when the oil smoke flows between the fan and the rear wall of the fan cover, the smoke collecting plate can limit the oil smoke from continuing to flow above the fan, thereby reducing the amount of oil smoke diffusion above the fan, and causing the oil smoke to gather at the first air inlet, thereby improving the smoke extraction effect of the fan and further increasing the smoke exhaust rate of the range hood.

[0017] In some embodiments of the present application, one end of the smoke collecting plate is located below the other end of the smoke collecting plate opposite thereto.

[0018] Through the above arrangement, when the oil smoke flows to the first air inlet, it can flow into the first air inlet more quickly under the guidance of the smoke collecting plate, thereby further improving the smoke exhaust rate of the range hood and improving the user experience of the range hood.

[0019] In some embodiments of the present application, the range hood further includes a guide plate assembly. The guide plate assembly is disposed in the smoke collecting chamber. The guide plate assembly includes a first guide plate and a second guide plate. The first guide plate, the first guide plate is disposed 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 hood and is connected to the third air inlet, and the smoke inlet is opened on the front wall surface of the smoke hood. The second guide plate, the second guide plate is disposed 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 hood and is connected to the third air inlet.

[0020] Through the above-mentioned configuration, the ventilation chamber 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 ventilation chamber, the oil smoke can flow through the smoke collecting chamber, the ventilation chamber, 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.

[0021] By setting 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 third air inlet, 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 ventilation chamber.

[0022] 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 ventilation chamber, thereby improving the smoke extraction effect of the range hood and improving the user experience of the range hood.

[0023] 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.

[0024] Through the above arrangement, during the operation of the range hood, the first smoke partition plate can separate part of the smoke entering the smoke collecting chamber from the first inlet and part of the smoke entering the smoke collecting chamber from the second inlet, thereby reducing the amount of the smoke entering the smoke collecting chamber from the first inlet and the smoke entering the smoke collecting chamber from the second inlet intersecting in the smoke collecting chamber. In this way, part of the smoke between the first smoke partition plate and the first guide plate can flow more smoothly into the ventilation chamber, and part of the smoke between the first smoke partition plate and the second guide plate can flow more smoothly into the ventilation chamber, thereby further improving the guiding effect of the guide plate assembly on the smoke, so as to further improve the smoke exhaust rate of the range hood.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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 ventilation chamber more smoothly along the guide plate assembly, thereby further improving the air suction effect of the range hood.

[0029] In a second aspect of the present application, a range hood is provided, comprising a smoke collecting hood, a fan cover and a fan. The smoke collecting hood is formed with a smoke collecting cavity and a smoke inlet connected to the smoke collecting cavity, and the smoke inlet is connected to the outside of the range hood. The fan cover comprises a bottom plate and a surrounding plate, the surrounding plate is connected to the top of the bottom plate and surrounds the bottom plate so that the bottom plate and the surrounding plate form a ventilation cavity with an opening at the upper end. The fan is arranged in the ventilation cavity and connected to the fan cover, and the fan is used to discharge the oil smoke in the ventilation cavity to the outside. A first air inlet is provided on one side of the fan close to the rear wall of the fan cover, and a second air inlet is provided on one side of the fan close to the front wall of the fan cover.

[0030] The bottom plate includes a first connecting plate and a second connecting plate. The first connecting plate is connected to the enclosure plate, the first connecting plate is located below the first air inlet, and the first connecting plate is provided with a third air inlet. The second connecting plate is connected to the enclosure plate. The second connecting plate is connected to a side of the first connecting plate close to the second air inlet. One end of the second connecting plate is away from the first connecting plate and is located above one end of the second connecting plate close to the first connecting plate.

[0031] 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

[0059] 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.

[0060] Based on this, the present application provides a range hood, such as Figure 1 , Figure 2 As shown, the range hood 10 includes a smoke collecting hood 2 , which is formed with a smoke collecting cavity 21 and a smoke inlet 22 communicating with the smoke collecting cavity 21 , and the smoke inlet 22 is communicated with the outside of the range hood 10 .

[0061] like Figure 1 , Figure 2 As shown, the range hood 10 further includes a fan cover 1, which includes a bottom plate 12 and a surrounding plate 13. The surrounding plate 13 is connected to the top of the bottom plate 12 and surrounds the bottom plate 12 so that the bottom plate 12 and the surrounding plate 13 enclose a ventilation cavity 11 with an upper opening. Specifically, the upper opening of the ventilation cavity 11 is connected to the outdoors.

[0062] like Figure 3 , Figure 4 As shown, the range hood 10 further includes a fan 3, which is disposed in the ventilation cavity 11 and connected to the fan cover 1, and is used to discharge the fumes in the ventilation cavity 11 to the outside. A first air inlet 31 is provided on one side of the fan 3 close to the rear wall 15 of the fan cover, and a second air inlet 32 ​​is provided on one side of the fan 3 close to the front wall 14 of the fan cover.

[0063] Specifically, during the operation of the fan 3 , the fumes in the kitchen can be sucked into the smoke collecting chamber 21 , and then sucked into the ventilation chamber 11 , and discharged to the outdoors under the action of the fan 3 .

[0064] like Figure 4 , Figure 5 As shown, the bottom plate 12 includes a first connecting plate 121 and a second connecting plate 122. The first connecting plate 121 is connected to the enclosure 13, and is located below the first air inlet 31. The first connecting plate 121 is provided with a third air inlet 1211.

[0065] Exemplarily, the first connecting plate 121 may be located in the smoke collecting chamber 21 , that is, the fan cover 1 partially extends into the smoke collecting chamber 21 .

[0066] Exemplarily, the first connecting plate 121 may be connected above the smoke collecting chamber 21 , that is, the entire fan cover 1 is located above the smoke collecting chamber 21 .

[0067] Specifically, Figure 6 As shown, along the first horizontal direction ( Figure 6 The first horizontal direction is parallel to the plane where the smoke inlet 22 is located, and the opposite side edges of the smoke inlet 22 are respectively located on the two sides of the third air inlet 1211.

[0068] like Figure 4 As shown, the second connecting plate 122 is connected to the enclosure 13 , and the second connecting plate 122 is connected to a side of the first connecting plate 121 close to the second air inlet 32 ​​.

[0069] In this way, after the oil smoke enters the ventilation chamber 11 from the third air inlet 1211, part of the oil smoke can directly flow into the first air inlet 31 along the gap between the fan 3 and the rear wall 15 of the fan cover, and the other part of the oil smoke will enter the gap between the fan 3 and the front wall 14 of the fan cover along the gap between the fan 3 and the second connecting plate 122, and then flow into the second air inlet 32, and then be discharged outdoors by the fan 3.

[0070] In some examples, a filter is provided at the third air inlet 1211 , and oil droplets in the oil smoke will be filtered by the filter and condensed in the smoke collecting chamber 21 .

[0071] 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.

[0072] 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.

[0073] Among them, 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 10.

[0074] In some examples, such as Figure 7 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.

[0075] 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.

[0076] In the related art, in order to improve the efficiency of the fan 3 in extracting oil smoke and to reasonably utilize the space, the smoke collecting hood 2 is located below the first air inlet 31 of the fan 3 .

[0077] In this way, after the oil smoke enters the smoke collecting chamber 21, it can smoothly enter the first air inlet 31 of the fan 3. However, when the oil smoke enters the second air inlet 32 ​​of the fan 3, it needs to change its flow direction, and thus will encounter greater resistance, which will cause the flow rate of this part of the oil smoke to be slower, affecting the smoke exhaust rate of the range hood 10, thereby affecting the user's experience of the range hood 10.

[0078] Based on this, in the range hood 10 provided in the present application, if Figure 4 , Figure 5 As shown, one end of the second connecting plate 122 away from the first connecting plate 121 is located above one end of the second connecting plate 122 close to the first connecting plate 121 .

[0079] Through the above-mentioned arrangement, when the oil smoke flows between the fan 3 and the second connecting plate 122, since the end of the second connecting plate 122 away from the first connecting plate 121 is located above the end of the second connecting plate 122 close to the first connecting plate 121, the oil smoke will gradually flow toward the direction close to the fan 3 and gather together until it contacts the front wall surface 14 of the fan cover. At this time, the oil smoke will continue to flow upward along the front wall surface 14 of the fan cover and finally flow into the second air inlet 32.

[0080] In this way, compared with the oil smoke flowing horizontally between the fan 3 and the second connecting plate 122, when the oil smoke flows from between the fan 3 and the second connecting plate 122 to between the fan 3 and the front wall 14 of the fan cover, the flow direction of the oil smoke only needs to change at a smaller angle, and the oil smoke changes its flow direction more smoothly. This can reduce the resistance encountered by the oil smoke in the process of flowing to the second air inlet 32, so that the oil smoke can flow more smoothly in the ventilation chamber 11, thereby accelerating the flow rate of the oil smoke, thereby accelerating the exhaust rate of the range hood 10, and improving the user experience of the range hood 10.

[0081] Based on the above, in some embodiments, such as Figure 4 , Figure 5 As shown, the first connecting plate 121 includes a first plate section 1212 and a second plate section 1213. The first plate section 1212 is located in the smoke collecting chamber 21 and connected to the enclosure 13, and the first plate section 1212 is provided with a third air inlet 1211. The second plate section 1213 is connected between the first plate section 1212 and the second connecting plate 122, and one end of the second plate section 1213 connected to the first plate section 1212 is located below one end of the second plate section 1213 connected to the second connecting plate 122, and is located on the side of the second plate section 1213 connected to the second connecting plate 122 close to the rear wall 25 of the smoke collecting hood.

[0082] Exemplarily, an edge of the first plate segment 1212 close to the second connecting plate 122 is connected to a lower edge of the second plate segment 1213 .

[0083] For example, a section of the edge of the second connecting plate 122 close to the rear wall surface 25 of the smoke collecting hood may be connected to the upper end edge of the second plate section 1213 .

[0084] Through the above-mentioned arrangement, when the oil smoke flows along the second plate section 1213 to the gap between the fan 3 and the second connecting plate 122, the oil smoke will flow in the direction close to the second connecting plate 122. Compared with the vertical arrangement of the second plate section 1213, the oil smoke can enter the gap between the fan 3 and the second connecting plate 122 more smoothly, and thus enter the second air inlet 32. This can further accelerate the flow rate of the oil smoke, thereby further accelerating the exhaust rate of the range hood 10 and improving the user experience of the range hood 10.

[0085] On this basis, in some embodiments, such as Figure 4 As shown, the front wall surface 24 of the smoke collecting hood is in contact with the second plate section 1213 and is parallel to the second plate section 1213 , and the smoke inlet 22 is opened on the front wall surface 24 of the smoke collecting hood.

[0086] In this way, after entering the smoke collecting chamber 21, the oil smoke can gradually flow along the front wall of the smoke collecting chamber 21 towards the direction close to the third air inlet 1211. Since the front wall surface 24 of the smoke collecting hood is parallel to the second plate section 1213, after entering the ventilation chamber 11, the oil smoke does not need to change its flow direction and can continue to flow along the second plate section 1213. In this way, the oil smoke can flow more smoothly in the ventilation chamber 11, so as to further speed up the smoke exhaust rate of the range hood 10.

[0087] like Figure 4 As shown, the range hood 10 further includes a smoke collecting plate 5, which is disposed in the ventilation cavity 11 and is located on a side of the first air inlet 31 away from the second air inlet 32. One end of the smoke collecting plate 5 is connected to the upper edge of the first air inlet 31, and the other end of the smoke collecting plate 5 is connected to the enclosure 13.

[0088] Through the above-mentioned arrangement, when the oil smoke flows between the fan 3 and the rear wall 15 of the fan cover, the smoke collecting plate 5 can limit the oil smoke from continuing to flow above the fan 3, thereby reducing the amount of oil smoke diffusion above the fan 3, and causing the oil smoke to gather at the first air inlet 31, thereby improving the smoke extraction effect of the fan 3, and further increasing the smoke exhaust rate of the range hood 10.

[0089] On this basis, in some embodiments, such as Figure 4 As shown, one end of the smoke collecting plate 5 is located below the other end opposite to the smoke collecting plate 5. That is, the end of the smoke collecting plate 5 connected to the rear wall surface 15 of the fan cover is located above the end of the smoke collecting plate 5 connected to the fan 3.

[0090] In this way, when the oil smoke flows to the first air inlet 31 , it can flow into the first air inlet 31 more quickly under the guidance of the smoke collecting plate 5 , thereby further improving the smoke exhaust rate of the range hood 10 and enhancing the user experience of the range hood 10 .

[0091] In some examples, such as Figure 4 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 31 and a second air inlet 32. The air outlet duct 34 is connected to the upper part of the body 33 and communicates with the outside.

[0092] In some examples, such as Figure 4 As shown, the fan 3 also includes a turbine 35, which is arranged in the body 33. The turbine 35 includes a first part 351 and a second part 352. The first part 351 is located on a side of the second part 352 close to the rear wall 15 of the fan cover. Along the arrangement direction of the rear wall 15 of the fan cover and the front wall 14 of the fan cover, the size of the first part 351 is L1, the size of the second part 352 is L2, the distance between the body 33 and the rear wall 15 of the fan cover is L3, and the distance between the body 33 and the front wall 14 of the fan cover is L4.

[0093] Among them, the ratio of L1 to L2 is close to the ratio of L3 to L4, specifically, 0.8*L1 / L2≤L3 / L4≤1.2*L1 / L2.

[0094] Exemplarily, the relationship between the ratio of L1 to L2 and the ratio of L3 to L4 can be L3 / L4=0.8*L1 / L2, L3 / L4=0.9*L1 / L2, L3 / L4=L1 / L2, L3 / L4=1.1*L1 / L2, L3 / L4=1.2*L1 / L2, etc.

[0095] In this way, the suction force of the first air inlet 31 and the second air inlet 32 ​​can match the gap between the rear wall 15 of the fan cover and the main body 33 and the gap between the front wall 14 of the fan cover and the main body 33 to improve the smoking efficiency of the fan 3.

[0096] On the basis of the above, in order to further improve the user's experience of using the range hood 10, in some embodiments, such as Figure 2 , Figure 8 As shown, the range hood 10 further includes a guide plate assembly 4 , which is disposed in the smoke collecting chamber 21 .

[0097] Specifically, Figure 6 , Figure 8 As shown, the guide plate assembly 4 includes a first guide plate 41 and a second guide plate 42 .

[0098] 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 third air inlet 1211 .

[0099] Specifically, in some embodiments, Figure 6 As shown, the first guide plate 41 is also connected to the front wall surface 24 of the smoke collecting hood.

[0100] like Figure 6 , Figure 8 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 third air inlet 1211 .

[0101] Specifically, in some embodiments, Figure 6 As shown, the second guide plate 42 is also connected to the front wall surface 24 of the smoke collecting hood.

[0102] 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.

[0103] Since the first guide plate 41 and the second guide plate 42 are both connected to the third air inlet 1211 , under the action of the fan 3 , most of the oil smoke will flow along the first guide plate 41 and the second guide plate 42 and enter the ventilation cavity.

[0104] 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 ventilation chamber, thereby improving the smoke extraction effect of the range hood 10 and improving the user experience of the range hood 10.

[0105] In addition, when the oil smoke flows from the smoke collecting chamber 21 to the ventilation chamber, compared with the oil smoke flowing in the entire smoke collecting chamber 21, the oil smoke can flow into the ventilation chamber 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.

[0106] In some embodiments, Fig. 9 As shown, one end of the first guide plate 41 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.

[0107] 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.

[0108] 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 ventilation cavity 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.

[0109] In some embodiments, Fig. 9 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.

[0110] 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.

[0111] 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 ventilation cavity 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.

[0112] 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.

[0113] In some examples, such as Fig.10 , Fig.11 As shown, the fan cover 1 partially extends into the smoke collecting chamber 21, and the portion of the fan cover 1 extending into the smoke collecting chamber 21 forms the third air inlet 1211. The first guide plate 41 and the second guide plate 42 are both connected to the outer wall surface of the third air inlet 1211.

[0114] Exemplarily, the first guide plate 41 may be a flat plate.

[0115] For example, Fig.12 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 third air inlet 1211, 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.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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 third air inlet 1211 .

[0120] 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 in the direction close to the third air inlet 1211 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 in the direction close to the third air inlet 1211. 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 ventilation cavity.

[0121] In this way, through the setting of the first sub-plate 411 and the second sub-plate 412, part of the oil smoke can be gathered at the third air inlet 1211 along the first sub-plate 411 and the second sub-plate 41, so as to flow into the ventilation cavity 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.

[0122] 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.

[0123] Exemplarily, the second guide plate 42 may be a flat plate.

[0124] For example, Fig.12 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 third air inlet 1211, 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.

[0125] 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.

[0126] 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.

[0127] 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.

[0128] Through the above arrangement, after entering the smoke collecting chamber 21 , the oil smoke will first flow to between the third sub-plate 421 and the first guide plate 41 , and then flow to the third air inlet 1211 .

[0129] 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 in the direction close to the third air inlet 1211 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 in the direction close to the third air inlet 1211. 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 ventilation chamber.

[0130] 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 third air inlet 1211 along the third sub-plate 421 and the fourth sub-plate 422, so as to flow into the ventilation cavity 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.

[0131] 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.

[0132] In some examples, one end of the first sub-plate 411 away from the third air inlet 1211 and one end of the third sub-plate 421 away from the third air inlet 1211 are both located directly above the oil receiving pan.

[0133] In this way, after being filtered by the filter at the third air inlet 1211, 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.

[0134] On this basis, in some embodiments, such as Fig.13 , Fig.14 As shown, one end of the first guide plate 41 away from the fan cover 1 extends to below the smoke inlet 22 .

[0135] 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 .

[0136] 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 under 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 ventilation chamber 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.

[0137] On this basis, in some embodiments, such as Fig.13 , Fig.14 As shown, one end of the second guide plate 42 away from the fan cover 1 extends to below the smoke inlet 22 .

[0138] 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 ventilation chamber 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.

[0139] In some embodiments, Fig.15 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.

[0140] 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 .

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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 ventilation cavity 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 ventilation cavity 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.

[0145] In addition, when the concentrations of 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 are different (for example, the user uses different kitchen utensils and stoves when cooking, more oil smoke is generated at the first inlet 221, and less oil smoke is generated at the second inlet 222), through the provision of the first smoke shielding plate 43, the oil smoke at the first inlet 221 and the oil smoke 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 smoke diffusing to the location where low-concentration oil smoke is located, so that both high-concentration oil smoke and low-concentration oil smoke can flow into the ventilation chamber more smoothly, thereby improving the smoking effect when the range hood 10 inhales oil smoke of different concentrations through the first inlet 221 and the second inlet 222 at the same time.

[0146] On this basis, in some embodiments, such as Fig.16 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.

[0147] 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 .

[0148] 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 that intersects 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 that intersects 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 ventilation chamber more smoothly.

[0149] 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.

[0150] For example, Fig.17 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.

[0151] 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.

[0152] 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.

[0153] Based on the above, in some embodiments, such as Fig.17 , Fig.18 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 .

[0154] 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 .

[0155] 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 .

[0156] 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.

[0157] 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 .

[0158] 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 ventilation cavity.

[0159] 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 ventilation cavity.

[0160] 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 ventilation chamber more smoothly along the guide plate assembly 4, thereby further improving the suction effect of the range hood 10.

[0161] 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.

[0162] In some examples, such as Fig.19 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.

[0163] Exemplarily, the first smoke isolation plate 43 and the fixing plate 45 may be separate structures or integrally formed structures.

[0164] Exemplarily, the second smoke isolation plate 44 and the fixing plate 45 may be separate structures or integrally formed structures.

[0165] 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.

[0166] In some embodiments, Fig. 20 , Fig.21 As 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 third air inlet 1211 at a side edge of the front wall surface 24 of the smoke collecting hood, and the lower end of the third guide plate 46 is connected to the upper edge of the smoke inlet 22.

[0167] 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 ventilation cavity 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.

[0168] In some examples, a thickness direction of the third guide plate 46 is perpendicular to the first horizontal direction.

[0169] In some examples, such as Fig.19 , Fig. 20 As shown, the third guide plate 46 is connected to the air inlet of the ventilation cavity. 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.

[0170] 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.

[0171] 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.

[0172] 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 .

[0173] On this basis, 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.
