For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] As described in the background art, during the actual use of the range hood, when the baffle is in the closed state, oil stains are likely to drip from the smoke inlet to the surface of the baffle and accumulate in its bottom area. At the same time, the oil stains are easy to flow out from the bottom of the baffle. These long-term accumulated oil stains not only have extremely strong adhesion and are difficult to completely remove, seriously affecting the user experience; at the same time, the accumulated oil stains are also likely to appear on the smoke collecting hood panel, affecting the overall aesthetics of the range hood; and, if the oil stains flow out from the bottom of the baffle, it will also affect the user's comfort.

[0051] Based on this, please refer to Figures 1 - 14, embodiments of the present invention provide a smoke collecting hood 100 and a range hood 1000, which can effectively improve the above-mentioned technical problems. It can collect the oil stains at the smoke inlet, avoid the accumulation of oil stains, facilitate the user to clean, thereby improving the user's comfort and enhancing the overall aesthetics of the range hood 1000. The following will elaborate on the smoke collecting hood 100 and the range hood 1000 in detail.

[0052] Please refer to Figure 1 , Figure 1 is a schematic structural diagram of the range hood 1000 provided in this embodiment from the first perspective. Combining Figure 1 , the range hood 1000 includes a smoke collecting hood 100 and a main cabinet 200. The main cabinet 200 is arranged on the smoke collecting hood 100. The smoke collecting hood 100 is used to gather the cooking fumes. A blower is provided in the main cabinet 200. Through the negative pressure of the blower, the fumes in the smoke collecting hood 100 are sucked and discharged.

[0053] Specifically, please refer to Figure 2 and Figure 3 , Figure 2 is a schematic structural diagram of the smoke collecting hood 100 provided in this embodiment from the first perspective. Figure 3 is a schematic structural diagram of the smoke collecting hood 100 provided in this embodiment from the second perspective. Combining Figure 2 and Figure 3 , the smoke collecting hood 100 includes a smoke collecting hood body 10 and a deflector 30. An oil collecting groove 11 and an oil cup 12 are respectively provided at the front end and the rear end of the smoke collecting hood body 10. An oil guiding structure 13 is provided on one side of the smoke collecting hood body 10. The oil collecting groove 11 is communicated with the oil cup 12 through the oil guiding structure 13; and a first smoke inlet 14 is further provided on the smoke collecting hood body 10. The first smoke inlet 14 is located between the oil collecting groove 11 and the oil cup 12. The deflector 30 is movably connected to the front end of the smoke collecting hood body 10. The deflector 30 is used to open or close the first smoke inlet 14, and a oil receiving surface 39 is provided on the side of the deflector 30 close to the first smoke inlet 14; when the deflector 30 is in the closed state, the oil receiving surface 39 is used to receive the oil stains at the first smoke inlet 14 and guide the oil stains into the oil collecting groove 11.

[0054] That is to say, after the deflector 30 closes the first smoke inlet 14, it can receive the oil stains at the first smoke inlet 14 through the oil receiving surface 39 and guide the oil stains into the oil collecting groove 11; and the oil stains in the oil collecting groove 11 are further guided through the oil guiding structure 13 and finally flow into the oil cup 12 at the rear end of the smoke collecting hood body 10. Thus, the accumulation of oil stains at the smoke inlet and on the deflector 30 is avoided. The user only needs to clean the oil cup 12 regularly, and the cleaning operation is convenient. Furthermore, the user's comfort is improved and the overall aesthetics of the range hood 1000 is enhanced.

[0055] In this embodiment, when the deflector 30 is in the closed state, the deflector 30 is inclined, and the height of the end of the deflector 30 close to the oil sump 11 is less than the height of the end of the deflector 30 far from the oil sump 11. It is easy to understand that by arranging the deflector 30 in an inclined manner, the oil stains received by its oil receiving surface 39 can directly flow from a high place to a low place under the action of gravity, that is, flow into the oil sump 11, thereby improving the oil stain collection efficiency.

[0056] It should be noted that the interior of the diversion structure has a channel for the flow of oil stains. In order to facilitate the oil stains in the oil sump 11 to flow into the oil cup 12, the diversion structure is also inclined, and the height of the end of the diversion structure close to the oil sump 11 is greater than the height of the end of the diversion structure close to the oil cup 12. That is to say, the oil stains in the oil sump 11 can also flow from a high place to a low place under the action of gravity, that is, the oil stains flow into the oil cup 12 through the internal channel of the diversion structure, thereby improving the oil stain collection efficiency.

[0057] Combined with Figure 3 , it should also be noted that specifically in this embodiment, oil guiding structures 13 are provided on both opposite sides of the smoke collecting hood body 10. As Figure 3 shown, the number of the oil guiding structures 13 is two. It can be understood that the two oil guiding structures 13 are respectively arranged on the left and right sides of the smoke collecting hood body 10, and the oil cup 12 is simultaneously lapped at the rear ends of the two oil guiding structures 13. In this way, the oil stains in the oil sump 11 can be diverted through the two oil guiding structures 13, thereby avoiding the accumulation of oil stains in the oil sump 11, improving the oil receiving rate of the oil cup 12, reducing the maintenance cost, and further enhancing the user's comfort during use. Of course, in some other embodiments, the oil guiding structure 13 can also be provided only on one side of the smoke collecting hood body 10.

[0058] Please continue to combine Figure 2 and Figure 3 , the bottom of the smoke collecting hood body 10 is provided with a step 16 and a smoke collecting platform 17. The front end, the step 16, the smoke collecting platform 17 and the rear end of the smoke collecting hood body 10 are connected in sequence. The deflector 30 is located below the step 16, and the first smoke inlet 14 is arranged on the smoke collecting platform 17. A storage space 21 is formed between the smoke collecting platform 17 and the step 16. When the deflector 30 is in the closed state, the deflector 30 is located in the storage space 21.

[0059] It is easy to understand that after the deflector 30 is closed, the deflector 30 can be hidden in the storage space 21, so that when the range hood 1000 is installed, most of the structures can be hidden in the wall cabinet 001, saving installation space and improving the aesthetics after installation.

[0060] Specifically, please refer to Figure 4 ,Figure 4 Schematic diagram of the assembly of the range hood 1000 provided in this embodiment with the wall cabinet 001. In combination with Figures 2 - 4 , when actually installing the range hood 1000, the bottom surface of the smoke collecting hood body 10 can be installed flush with the bottom surface of the wall cabinet 001, and the deflector 30 is hidden in the storage space 21. The oil cup 12 is located at the rear end of the bottom of the smoke collecting hood body 10 against the wall. When the user looks straight at the smoke collecting hood 100, only the oil cup 12 is exposed, which facilitates the grasping and resetting of the oil cup 12 during cleaning.

[0061] Furthermore, please refer to Figures 5 - 8 . Figure 5 Schematic diagram of the deflector 30 in the closed state of the range hood 1000 provided in this embodiment from the second perspective. Figure 6 is Figure 5 The partial enlarged view of the position A in Figure 7 Schematic diagram of the deflector 30 in the open state of the range hood 1000 provided in this embodiment from the second perspective. Figure 8 is Figure 7 The partial enlarged view of the position B in

[0062] In combination with Figures 5 - 8 , the smoke collecting hood 100 further includes an oil receiving plate 40. The oil receiving plate 40 is arranged at one end of the deflector 30 close to the oil collecting tank 11 and is used to guide the oil stain on the oil receiving surface 39. An avoidance opening 111 is formed on one side of the oil collecting tank 11 close to the oil cup 12. When the deflector 30 is in the closed state, the oil receiving plate 40 passes through the avoidance opening 111 and extends into the oil collecting tank 11. When the deflector 30 is in the open state, the oil receiving plate 40 is used to cooperate with the step 16.

[0063] As Figure 6 shown, specifically, during the process of the deflector 30 rotating and closing, the avoidance opening 111 can give way to the oil receiving plate 40. When the deflector 30 is in the closed state, the front end of the oil receiving plate 40 is exactly inside the oil collecting tank 11, and the deflector 30 is inclined. The angle between it and the bottom horizontal plane of the smoke collecting hood 100 is C. Therefore, the oil stain on the oil receiving surface 39 can flow back into the oil collecting tank 11 at the front end of the smoke collecting hood body 10 through the inclination of this angle under the guidance of the oil receiving plate 40, and then through the oil guiding structures 13 on both left and right sides of the smoke collecting hood body 10, and finally flow into the oil cup 12.

[0064] As Figure 8As shown, specifically, after the guide plate 30 is opened, the front end of the oil receiving plate 40 can cooperate with the step 16 to reduce the gap between the guide plate 30 and the step 16. During the use of the range hood 1000, on the one hand, it can prevent the escape of oil smoke. On the other hand, the front end of the oil receiving plate 40 can also play a certain role in guiding the oil smoke. For example, when the guide plate 30 is rotated to a certain angle, the front end of the oil receiving plate 40 can cooperate with the inclined wall of the connecting part of the step 16 and the smoke collecting platform 17 to better guide the oil smoke to the first smoke inlet 14, thereby improving the smoking effect of the range hood 1000.

[0065] It should be noted that in this embodiment, the oil receiving plate 40 is located on the oil receiving surface 39, which can facilitate the diversion of oil from the oil receiving surface 39. When the deflector 30 is closed, the deflector 30 can have a larger tilt angle, at which time the oil receiving plate 40 can also abut against the bottom of the avoidance opening 111, thereby preventing oil from overflowing from the avoidance opening 111. Of course, in other embodiments, the oil receiving plate 40 can also be located on the side of the deflector 30 away from the step 16, that is, opposite the oil receiving surface 39, and the oil receiving plate 40 can partially extend from the front end of the deflector 30 to facilitate receiving oil from the front end of the oil receiving surface 39.

[0066] In addition, it should be noted that in some other embodiments, the oil receiving plate 40 may not be provided, and the front end of the guide plate 30 may be directly matched with the oil collecting tank 11 or the step 16. Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of another embodiment of the guide plate 30 in a closed state cooperating with the oil collecting tank 11. Figure 10 Schematic diagram of the deflector 30 provided in other embodiments cooperating with the step 16 in the open state.

[0067] Combine Figure 9 and Figure 10 The oil collecting tank 11 has a relief opening 111 on its side near the oil cup 12. When the deflector 30 is closed, the end of the deflector 30 near the oil collecting tank 11 passes through the relief opening 111 and extends into the oil collecting tank 11. When the deflector 30 is open, the end of the deflector 30 near the oil collecting tank 11 engages with the step 16. This eliminates the need for an oil receiving plate 40, reducing manufacturing costs and improving assembly efficiency.

[0068] Please continue to combine Figure 2, in this embodiment, the smoke collecting platform 17 is inclined, and the height of the end of the smoke collecting platform 17 close to the step 16 is greater than the height of the end of the smoke collecting platform 17 far from the step 16; the oil cup 12 is used to receive the oil stains on the smoke collecting platform 17. Through the inclined setting of the smoke collecting platform 17, the oil stains on the surface of the smoke collecting platform 17 can also flow into the oil cup 12 under the action of gravity, reducing the accumulation of oil stains, thereby reducing the cleaning frequency of users; moreover, this inclined surface also facilitates the user to clean the smoke collecting platform 17, improving the use comfort.

[0069] Furthermore, the smoke collecting hood body 10 is also provided with a second smoke inlet 15, and the second smoke inlet 15 is arranged on the smoke collecting platform 17. The step 16, the first smoke inlet 14, the second smoke inlet 15 and the oil cup 12 are arranged at intervals in sequence. It is easy to understand that in actual use, the second smoke inlet 15 is in an open state all the time and can be regarded as the main smoke inlet, while the deflector 30 is used to close the first smoke inlet 14, and the first smoke inlet 14 can be regarded as the secondary smoke inlet. In this way, according to different cooking scenarios, the first smoke inlet 14 can be selectively opened or closed to play the role of energy saving or improving the smoke suction effect.

[0070] Specifically, when the amount of oil fume generated during cooking is small, the deflector 30 closes the first smoke inlet 14 and only smokes through the second smoke inlet 15. At this time, the fan in the main chassis 200 is in the weak gear mode, that is, the main motor in the fan runs in the weak gear, which can play the role of energy saving. When the amount of oil fume generated during cooking is large, the deflector 30 opens the first smoke inlet 14, and the first smoke inlet 14 and the second smoke inlet 15 jointly intake smoke, which can increase the air intake area. At this time, the fan in the main chassis 200 is in the strong gear mode, that is, the main motor in the fan runs in the strong gear, thereby improving the smoke suction effect and enhancing the comfort of the user during the cooking process.

[0071] Please combine Figure 2 and Figure 7 , in the case where the deflector 30 closes the first smoke inlet 14, in order to improve the smoke suction effect of the second smoke inlet 15, in this embodiment, the end of the deflector 30 far from the oil collecting tank 11 is provided with a bent portion 31. In the case where the deflector 30 is in the closed state, the bent portion 31 is used to deflect the oil fume to the second smoke inlet 15. As Figure 7 shown, it should be noted that when the deflector 30 is in the open state, the bent portion 31 is arranged vertically downward, and can also play the role of smoke cage, better guiding the oil fume to flow to the first smoke inlet 14 and the second smoke inlet 15. That is to say, when the deflector 30 is closed, it can deflect the oil fume to the second smoke inlet 15 through the bent portion 31, and when the deflector 30 is open, it can cage the oil fume through the bent portion 31, thereby improving the smoke suction performance of the range hood 1000 as a whole.

[0072] Further, when the deflector 30 is in the closed state, the bent portion 31 is inclined, and the height of the end of the bent portion 31 close to the second smoke inlet 15 is greater than the height of the end of the bent portion 31 away from the second smoke inlet 15. As Figure 7 shown, the inclination angle between the bent portion 31 and the horizontal plane at the bottom of the smoke collecting hood body 10 is D. By the inclined setting of the bent portion 31, the oil fume can be guided, and the oil fume can be better guided to the second smoke inlet 15, thereby further improving the smoking effect.

[0073] Please continue to combine Figure 2 and Figure 3 The smoke collecting hood body 10 further includes a partition member 18. The partition member 18 is arranged on the smoke collecting platform 17 and is located between the first smoke inlet 14 and the second smoke inlet 15. When the deflector 30 is in the closed state, the end of the deflector 30 away from the oil collecting tank 11 abuts against the partition member 18 to separate the first smoke inlet 14 from the second smoke inlet 15; and the partition member 18 is used to block the oil stain at the first smoke inlet 14 to guide the oil stain to the oil receiving surface 39.

[0074] By arranging the partition member 18, on the one hand, it can cooperate with the deflector 30 to separate the first smoke inlet 14 and the second smoke inlet 15, so as to prevent the oil fume from entering the first smoke inlet 14 through the gap when the deflector 30 closes the first smoke inlet 14, and ensure the smoking effect of the second smoke inlet 15. On the other hand, the partition member 18 can also prevent the oil stain on the surface of the first smoke inlet 14 from flowing to the second smoke inlet 15, and the oil stain is blocked at the partition member 18. When the deflector 30 opens the first smoke inlet 14, the oil stain blocked at the partition member 18 will not directly fall under the action of gravity, and when the deflector 30 closes the first smoke inlet 14, the deflector 30 abuts against the partition member 18, so that the accumulated oil stain is guided to the oil collecting tank 11 through the oil receiving surface 39, improving the efficiency of oil stain collection.

[0075] Specifically, in this embodiment, when the deflector 30 is in the closed state, the bent portion 31 abuts against the partition member 18. That is to say, the oil stain blocked at the partition member 18 flows to the bent portion 31, and the inclined setting of the bent portion 31 also improves the guiding effect on the oil stain, thereby further improving the oil stain collection efficiency.

[0076] It should be noted that in this embodiment, when the deflector 30 is in the closed state, the bent portion 31 abuts against the side of the partition member 18 close to the second smoke inlet 15, which can improve the sealing effect and further prevent oil fume from entering the first smoke inlet 14 through the gap; moreover, the bent shape of the bent portion 31 can wrap a part of the partition member 18, thereby enhancing the stability of the deflector 30 in the closed state. Of course, in other embodiments, the bent portion 31 can also abut against the side of the partition member 18 close to the first smoke inlet 14, or abut against the middle position of the partition member 18.

[0077] During the cooking process, due to the uncertainty of the flow path of the oil fume, in order to suck the oil fume at different positions, the number of the first smoke inlets 14 can be multiple, and the multiple first smoke inlets 14 are arranged at intervals, and the deflector 30 is used to close the multiple first smoke inlets 14 simultaneously. Similarly, the number of the second smoke inlets 15 can also be set to be multiple, and the multiple second smoke inlets 15 are arranged at intervals. Similarly, the number of the partition members 18 can also be set to be multiple, and the multiple partition members 18 are arranged at intervals, and the bent portion 31 is used to abut against the multiple partition members 18 simultaneously.

[0078] It should be noted that in this embodiment, the number of the first smoke inlet 14, the second smoke inlet 15 and the partition member 18 is two, that is, the two partition members 18 cooperate with the bent portion 31 to separate the two first smoke inlets 14 and the two second smoke inlets 15. Of course, in other embodiments, the number of the first smoke inlet 14, the second smoke inlet 15 and the partition member 18 can also be one, three or four, etc., and the specific number needs to be determined according to the actual use situation and design requirements.

[0079] Please continue to combine Figure 3 , specifically, the first smoke inlet 14 includes a plurality of strip-shaped holes 141, the plurality of strip-shaped holes 141 are arranged at intervals, and a flanging facing the inside of the smoke collecting hood body 10 is provided at the edge of each strip-shaped hole 141. Through the arrangement of the plurality of strip-shaped holes 141, the smoke intake amount of each smoking area can be increased, and the oil fume can be sucked at multiple positions. At the same time, by arranging the flanging at the edge of the strip-shaped hole 141, it can prevent the oil stain from flowing down from the first smoke inlet 14.

[0080] Furthermore, in order to improve the filtering effect of the second smoke inlet 15, the smoke collecting hood 100 further includes a filter net 80, and the filter net 80 is arranged at the second smoke inlet 15.

[0081] Optionally, the smoke collecting hood 100 further includes a first light source 51 and a second light source 52. The first light source 51 and the second light source 52 are spaced apart and disposed on the smoke collecting platform 17. The first light source 51 corresponds to the first smoke inlet 14, and the second light source 52 corresponds to the second smoke inlet 15. When the deflector 30 is in the closed state, the deflector 30 is used to shield the first light source 51.

[0082] That is to say, during the actual cooking process, the first light source 51 or the second light source 52 can be made to emit light according to the usage scenario. Specifically, when the amount of oil fume is small, the deflector 30 closes the first smoke inlet 14 and shields the first light source 51. At this time, the second light source 52 is turned on to emit light, while the first light source 51 is turned off, which can save energy consumption. When the amount of oil fume is large, the deflector 30 opens the first smoke inlet 14 and makes the first light source 51 unobstructed. At this time, both the first light source 51 and the second light source 52 are turned on to emit light, which can increase the illumination range, make the cooking sight brighter, and improve the user's comfort.

[0083] Combined with Figure 3 , in order to facilitate the installation of the first light source 51 and the second light source 52, the smoke collecting platform 17 is also provided with a groove 171. The first light source 51 and the second light source 52 are spaced apart and disposed in the groove 171. Through the setting of the groove 171, it can also avoid the formation of oil stains on the first light source 51 and the second light source 52 to a certain extent, and play a role in protecting the first light source 51 and the second light source 52.

[0084] Specifically, in this embodiment, the groove 171 is located between two partition members 18. The first light source 51 is located between two first smoke inlets 14, and the second light source 52 is located between two second smoke inlets 15. It can also be understood that the first light source 51 and the second light source 52 are located in the middle area of the smoke collecting platform 17, which can better illuminate the cooking area.

[0085] Please refer to Figure 11 and Figure 12 , Figure 11 is a schematic diagram of the deflector 30 in the closed state when the range hood 1000 provided in this embodiment is cooking. Figure 12 is a schematic diagram of the deflector 30 in the open state when the range hood 1000 provided in this embodiment is cooking. Combined with Figure 3 , Figure 11 and Figure 12 , the smoke collecting hood 100 further includes a temperature sensing module 60. The temperature sensing module 60 is disposed in the smoke collecting hood body 10 and is located at the front end of the smoke collecting hood body 10. The step 16 is provided with a first through hole 161, and the deflector 30 is provided with a second through hole 32. The second through hole 32 corresponds to the first through hole 161. The first through hole 161 and the second through hole 32 are used for the temperature sensing optical path of the temperature sensing module 60 to pass through.

[0086] like Figure 11 and Figure 12 As shown, the field of view angle E of the temperature sensing module 60 through the first through hole 161 and the second through hole 32 just covers the center of the cookware, and can detect the temperature of the cookware in real time. When the temperature of the cookware is within the set range of low-speed operation, the main motor of the fan runs at low speed, the guide plate 30 closes the first smoke inlet 14, and the oil smoke is sucked through the second smoke inlet 15. When the temperature detected by the temperature sensing module 60 exceeds the temperature of low-speed operation, the guide plate 30 opens the first smoke inlet 14, and the oil smoke is sucked through the first smoke inlet 14 and the second smoke inlet 15.

[0087] It should be noted that when the guide plate 30 is opened, it will block the temperature-sensitive light path for a short period of several seconds. At this time, a corresponding filtering program can be set to prevent misjudgment.

[0088] In order to facilitate the control of the rotation of the guide plate 30 and realize the opening and closing functions, the smoke hood 100 further includes a driving member 71 and a fixing bracket 72. Figure 13 , Figure 13 The assembly diagram of the guide plate 30, the driving member 71 and the fixing bracket 72 provided in this embodiment is shown in FIG. Figure 3 and Figure 13 The driving member 71 and the fixing bracket 72 are respectively arranged on two opposite sides of the smoke hood body 10, the driving member 71 is transmission-connected to one side of the guide plate 30, and the fixing bracket 72 is rotationally connected to the other side opposite to the guide plate 30.

[0089] Specifically, a first notch 35 and a second notch 36 are respectively provided on opposite sides of the guide plate 30. A first fixing member 37 is provided at the first notch 35, and a second fixing member 38 is provided at the second notch 36. The driving member 71 is transmission-connected to the first fixing member 37, and the fixing bracket 72 is rotationally connected to the second fixing member 38.

[0090] It should be noted that in this embodiment, the first fixing member 37 has a hexagonal inner hole, the second fixing member 38 has a circular inner hole, and the driving member 71 is a reduction motor. The head of the reduction motor's shaft has a corresponding hexagonal structure that can cooperate with the hexagonal inner hole of the first fixing member 37. The shaft on the fixing bracket 72 is inserted into the central inner hole of the second fixing member 38, thereby forming a set of rotation mechanisms for the deflector 30. It can be understood that when the reduction motor rotates clockwise, the deflector 30 flips outward to open, while when the reduction motor rotates counterclockwise, the deflector 30 flips inward to close.

[0091] Of course, in other implementations, the inner holes of the first fixing member 37 and the second fixing member 38 can also have other shapes, and other installation methods can also be adopted for the cooperation with the driving member 71 and the fixing bracket 72. In addition, other driving structures such as air cylinders or hydraulic cylinders can also be used for the driving member 71.

[0092] Please refer to Figure 1 and Figure 13 For the control of the opening and closing of the deflector 30, as well as the control of the corresponding cooperating reduction motor and main motor, it can also be achieved by gesture control or button touch. Specifically, a waving area 33 and a touch area 34 are also provided on the deflector 30. Correspondingly, the smoke collecting hood 100 also includes a waving module and a touch module. The waving module is located in the waving area 33, and the touch module is located in the touch area 34.

[0093] That is to say, during the actual cooking process, the user judges the amount of oil fume by himself / herself, and chooses to open or close the deflector 30 by waving. After the deflector 30 is opened, the user can also adjust the air volume of the fan, turn on or off the first light source 51, the second light source 52, and the deflector 30, etc. by gently pressing the button in the touch area 34.

[0094] Combined with Figure 1 and Figure 12 It should be noted that after the deflector 30 is opened, the touch area 34 is in the direct front of the user, and the deflector 30 is in an inclined state, which is convenient for the user to operate the touch button, conforms to the ergonomic design, and improves the user's comfort.

[0095] In addition, it should also be noted that in order to better control the range hood 1000, the waving function has the highest priority, followed by the touch function, and finally the temperature-sensing automatic control function.

[0096] To facilitate the understanding of the control logics of the waving function, the touch function, and the temperature-sensing automatic control function, please refer to Figure 14 , Figure 14 which is the control logic schematic diagram of the range hood provided in this embodiment. Combined with Figure 14 When the range hood 1000 is in the standby state, the deflector 30 is in the closed state and hidden in the storage space 21. The range hood 1000 can be turned on by a waving command. Specifically, with one wave, the main motor runs at a low speed, and at this time, the deflector 30 is in the closed state; then, by hovering the gesture, the main motor can be stopped.

[0097] When the amount of cooking fumes increases, wave your hand a second time, and the main motor runs at high speed. At the same time, the reduction motor works to drive the deflector 30 to turn outwards and open; wave your hand again to switch between the high and low speed gears of the main motor to adjust the opening and closing of the deflector 30; of course, you can also directly turn off the main motor and reset the reduction motor by hovering your hand gesture.

[0098] After waving your hand once, since the deflector 30 is in the open state, the touch buttons on the deflector 30 are exposed at this time. The user can directly operate the button commands to manually switch the gears of the main motor to adjust the size of the fan air volume. At the same time, the user can also operate to turn on or off the first light source 51, the second light source 52, and the deflector 30, etc.

[0099] In addition, after waving your hand once, if the user does not continue to wave their hand or operate the button commands, the temperature sensing module 60 will detect the temperature of the cookware in real time. When the temperature of the cookware exceeds the preset temperature, the reduction motor will be automatically controlled to open the deflector 30 and switch the main motor to high gear.

[0100] In summary, the embodiments of the present invention provide a smoke collecting hood 100 and a range hood 1000. The smoke collecting hood 100 includes a smoke collecting hood body 10 and a deflector 30. An oil collecting groove 11 and an oil cup 12 are respectively provided at the front end and the rear end of the smoke collecting hood body 10. An oil guiding structure 13 is provided on one side of the smoke collecting hood body 10. The oil collecting groove 11 is communicated with the oil cup 12 through the oil guiding structure 13; and the smoke collecting hood body 10 is also provided with a first smoke inlet 14, and the first smoke inlet 14 is located between the oil collecting groove 11 and the oil cup 12; the deflector 30 is movably connected to the front end of the smoke collecting hood body 10. The deflector 30 is used to open or close the first smoke inlet 14, and a oil receiving surface 39 is provided on the side of the deflector 30 close to the first smoke inlet 14; when the deflector 30 is in the closed state, the oil receiving surface 39 is used to receive the oil stain at the first smoke inlet 14 and guide the oil stain into the oil collecting groove 11. That is to say, after the deflector 30 closes the first smoke inlet 14, it can receive the oil stain at the first smoke inlet 14 through the oil receiving surface 39 and guide the oil stain into the oil collecting groove 11; and the oil stain in the oil collecting groove 11 is guided through the oil guiding structure 13 and finally flows into the oil cup 12 at the rear end of the smoke collecting hood body 10. Thus, the accumulation of oil stains on the smoke inlet and the deflector 30 is avoided. The user only needs to clean the oil cup 12 regularly, and the cleaning operation is convenient. Furthermore, the user's comfort is improved, and the overall aesthetics of the range hood 1000 is enhanced.

[0101] The range hood 1000 includes a smoke collecting hood 100, which has all the functions and beneficial effects of this smoke collecting hood 100.

[0102] The above are only specific embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
