[0035] The present application is described in detail below. Examples of embodiments of the present application are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. In addition, if the detailed description of the known technology is not necessary for the features of the present application shown, it will be omitted. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0036] The inventors of this application have conducted research and found that as the shape of range hoods evolves, customers require that the space occupied by the range hood be as small as possible. This has led to a decrease in the space occupied by the smoke collection chamber 11 and a decrease in the size of the flap 2 of the smoke collection chamber 11. Currently, range hoods on the market have the following shapes:

[0037] 1. The smoke hood is placed close to the wall, and the flap 2 is turned outward to form a smoke trapping structure in the working state; the flap 2 is reset in the non-working state;

[0038] 2. The smoke hood is set close to the bottom of the wall cabinet, and the flap 2 forms a smoke collection structure in the working state; the flap 2 is reset in the non-working state;

[0039] 3. The smoke collecting hood is a liftable structure. The smoke collecting chamber 11 is lowered close to the smoke source in the working state, and is raised and hidden in the wall cabinet in the non-working state.

[0040] From the above, it can be seen that the space occupied by the fume hood in the working state is larger than the space occupied in the non-working state. The more space the fume hood occupies, the lower the convenience for the user. In addition, the oil stains on the outer wall of the fume hood will slide along the outer wall of the fume hood and drip onto the stove, polluting the kitchen, requiring the user to clean it, and reducing the user experience.

[0041] The smoke hood and range hood provided in this application are intended to solve the above technical problems in the prior art.

[0042] The following describes in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments.

[0043] like Figure 1-6 As shown, an embodiment of the present application provides a smoke collection hood, which mainly includes a shell 1, a flap 2, and a flow guide 3. The shell wall of the shell 1 is arranged to form a smoke collection chamber 11. The shell 1 is provided with a low-level smoke inlet 12 connected to the smoke collection chamber 11. Oil and dirt on the shell 1 flow toward the low-level smoke inlet 12 under the action of gravity; the flap 2 and the flow guide 3 are both arranged near the low-level smoke inlet 12 and movably connected to the shell 1; when the flap 2 is in a first position, the low-level smoke inlet 12 is closed and the flow guide 3 is in a avoidance position; when the flap 2 is in a second position, the low-level smoke inlet 12 is opened and the flow guide 3 is in a diversion position, which is used to guide the oil and dirt flowing into the low-level smoke inlet 12 to flow toward the inside of the smoke collection chamber 11.

[0044] In this embodiment, the smoke hood is horizontally disposed. The housing 1 is provided with at least one smoke inlet, which serves as a low-position smoke inlet 12. Oil stains may be located above the low-position smoke inlet 12. The oil stains flow under gravity to the low-position smoke inlet 12, which is located below the oil stains above the low-position smoke inlet 12. In this embodiment, the "low" in "low-position smoke inlet 12" refers to the area above the smoke inlet.

[0045] In some embodiments, the housing 1 includes a front wall 13 that slopes downward and forward, with a low-positioned smoke inlet 12 located at the lower portion or bottom of the front wall 13. Oil and dirt on the outer wall of the front wall 13 flows along the front wall 13 under the action of gravity and may flow into the low-positioned smoke inlet 12. The remaining walls of the housing 1 are not labeled.

[0046] The flap 2 is used to move between a first position and a second position, and the low-position smoke inlet 12 is opened or closed by changing the position. The guide member 3 can be arranged in the smoke collecting chamber 11. When the flap 2 is in the second position, the low-position smoke inlet 12 is in an open state to connect the smoke collecting chamber 11 with the outside, and the external smoke can enter the smoke collecting chamber 11 through the low-position smoke inlet 12. At this time, the guide member 3 is in the guide position, and the guide member 3 forms a matching relationship with the low-position smoke inlet 12. The guide member 3 in the guide position plays a role in guiding the oil and dirt flowing to the low-position smoke inlet 12 to flow toward the inside of the smoke collecting chamber 11; the "avoidance position" refers to the position where the guide member 3 does not come into contact with the flap 2 when the flap 2 is in the first position. The "avoidance position" is not a single specified position, and can be any one of multiple positions.

[0047] The smoke hood provided in this embodiment includes a flap 2 and a guide member 3 that can move relative to the shell 1. When the flap 2 moves to the first position, the guide member 3 is located in the avoidance position to avoid the flap 2. When the flap 2 is in the first position, the low-level smoke inlet 12 is closed; when the flap 2 is in the second position, the low-level smoke inlet 12 is opened, and the guide member 3 moves to the guide position to guide the oil flowing to the low-level smoke inlet 12 to flow toward the inside of the smoke collecting chamber 11, so as to prevent the oil on the outer wall of the smoke hood from dripping onto the stove and polluting the kitchen, thereby reducing user cleaning and improving user experience.

[0048] like Figure 3 and 4 As shown, Figure 3 and 4 The dotted line is the boundary line between the first shell portion 14 and the second shell portion 15 .

[0049] Based on the above embodiments, in a specific embodiment, the housing 1 includes a first shell portion 14 and a second shell portion 15 that are connected to each other. Figure 3 and Figure 4 The dotted line rear side of the middle housing 1 is the second housing portion 15, and the dotted line front side is the first housing portion 14. The second housing portion 15 is located above the first housing portion 14 and protrudes forward of the second housing portion 15. The aforementioned front housing wall 13 is mounted on the second housing portion 15. The bottom of the first housing portion 14 is provided with a horizontal housing wall. This housing wall defines a high-positioned smoke outlet 16 that communicates with the smoke collection chamber 11 and is higher than the low-positioned smoke outlet.

[0050] like Figure 4 As shown, as an optional embodiment, the guide member 3 rotates relative to the shell 1; when the guide member 3 is in the avoidance position, it is arranged in the smoke collecting chamber 11; when the guide member 3 is in the guide position, the free end of the guide member 3 is connected to the edge of the low-position smoke inlet 12 and extends toward the inside of the smoke collecting chamber 11.

[0051] Based on the previous embodiment, in this embodiment, the main body of the deflector 3 is a plate-like structure, with one end of the plate-like structure being a connecting end and the other being a free end. The connecting end is rotatably connected to the housing 1. The connection point between the connecting end and the housing 1 is higher than the aforementioned low-position smoke inlet 12, and the deflector 3 and the low-position smoke inlet 12 correspond to each other. The deflector 3 rotates upward or downward relative to the housing 1 to move between the avoidance position and the diversion position. Specifically, the deflector 3 in the avoidance position rotates downward to the diversion position, and conversely, the deflector 3 in the diversion position rotates upward to the avoidance position.

[0052] The length of the plate-like structure matches the length of the smoke inlet. When the deflector 3 is in the diversion position, the free end of the deflector 3 is lower in height than the connection end. The free end of the plate deflector 3 connects to the edge of the low-position smoke inlet 12, forming a diversion structure. Oil and dirt flowing into the low-position smoke inlet 12 can flow toward the free end of the deflector 3. The free end of the deflector 3 extends toward the inside of the smoke collection chamber 11, that is, extends backward. Oil and dirt on the free end of the deflector 3 flows backward along the free end and drips into the smoke collection chamber 11, thus preventing the oil and dirt from dripping outside the housing 1.

[0053] like Figure 4 and 6 As shown, as an optional embodiment, the free end of the guide member 3 includes a first extension portion 31 and a second extension portion 32 connected to each other; when the guide member 3 is in the guide position, the first extension portion 31 extends toward the outside of the shell 1 on the side opposite to the second extension portion 32, and is connected to the edge of the smoke inlet, for guiding the oil flowing into the smoke inlet to flow toward the second extension portion 32; the second extension portion 32 extends toward the smoke collecting chamber 11 on the side opposite to the first extension portion 31, for guiding the oil flowing to the second extension portion to flow toward the inside of the smoke collecting chamber 11.

[0054] like Figure 6 As shown, in some embodiments, Figure 6 The middle dotted line is the boundary line between the first extension portion 31 and the second extension portion 32 . The left side of the dotted line is the first extension portion 31 , and the right side of the dotted line is the second extension portion 32 .

[0055] Based on the aforementioned embodiment, in this embodiment, the free end of the flow guide 3 is a hook-shaped structure, and the connected first extension portion 31 and second extension portion 32 form a protruding portion of the hook-shaped structure. When the flow guide 3 is in the flow-guiding position, the first extension portion 31 is located in front of the second extension portion 32, and the first extension portion 31 extends forward. The bottom of the first extension portion 31 has a first flow-guiding surface for guiding flow. The first flow-guiding surface can be an inclined surface that is inclined downward and forward. When the flow guide 3 is in the flow-guiding position, the top of the first extension portion 31 is connected to the upper edge of the low-position smoke inlet 12, so that the first flow-guiding surface is connected and matched with the outer surface of the housing 1, allowing oil and dirt to flow from the outer surface of the housing 1 to the first flow-guiding surface.

[0056] The bottom of the second extension portion 32 has a second guide surface, which can be an inclined surface that is inclined downward and forward. The second guide surface is connected to the first guide surface. The oil flowing to the first guide surface can flow to the second guide surface. The oil flowing to the second guide surface flows to an appropriate position and then gathers and drips under the action of gravity.

[0057] Optionally, the first guide surface and the second guide surface are located in the same plane.

[0058] Optionally, the first guide surface and the second guide surface are located in different planes, that is, the first guide surface and the second guide surface intersect at an angle.

[0059] like Figure 4-6 As shown, as an optional embodiment, a guide groove 33 is provided at the free end of the guide member 3. When the guide member 3 is in the guide position, the inlet end of the guide groove 33 faces the outside of the shell 1, and the outlet end of the guide groove 33 faces the smoke collecting chamber 11, which is used to guide the smoke to flow into the smoke collecting chamber 11.

[0060] Based on the previous embodiment, in this embodiment, the flow guide 3 serves both as an oil and gas guide. The flow guide groove 33 includes a channel structure for guiding the flue gas. When the flow guide 3 is in the flow-guiding position, the channel structure extends in a direction that intersects the horizontal direction, i.e., the channel structure extends in an inclined direction to match the flow direction of the flue gas. Optionally, the channel structure extends in a direction that tilts backward and downward. The lower end of the flow guide groove 33 serves as the inlet end of the channel structure, and the upper end of the flow guide groove 33 serves as the outlet end of the channel structure.

[0061] like Figure 4-6 As shown, as an optional embodiment, the free end of the guide member 3 is provided with a plurality of guide grooves 33 arranged at intervals. When the guide member 3 is in the guide position, the guide grooves 33 are provided on the side of the free end of the guide member 3 close to the smoke collecting chamber 11 and are recessed in the free end of the guide member 3.

[0062] Based on the aforementioned embodiment, in this embodiment, multiple spaced guide grooves 33 can smooth the smoke flow at the inhaler port, reducing noise and air intake resistance. When the guide member 3 is in the diversion position, the guide grooves 33 are located at the rear side of the guide member 3. The guide grooves 33 are concave forward of the free end of the guide member 3 and extend as far forward as possible to guide more smoke and increase diversion efficiency. The first and second guide surfaces connected above form a plane that slopes forward and downward, which serves as the end surface of the inlet end of the guide grooves 33.

[0063] As an optional implementation, the flap 2 is linked to the flow guide 3 .

[0064] By adopting the above scheme, by driving one of the flap 2 and the guide member 3 to move under the action of external force, the other can be driven to move at the same time; more specifically, when the flap 2 is in the first position, the guide member 3 is in the avoidance position, and the flap 2 moves from the first position to the second position, and the guide member 3 moves from the avoidance position to the diversion position; when the flap 2 is in the second position, the guide member 3 is in the diversion position, and the flap 2 moves from the second position to the first position, and the guide member 3 moves from the diversion position to the avoidance position.

[0065] like Figure 7-8As shown, as an optional embodiment, the smoke hood further includes a drive motor 4 and a follower 5. The follower 5 is connected to the output end of the drive motor 4, the flap 2, and the air guide 3. The drive motor 4 drives the follower 5 to move in a first direction, whereby the follower 5 pushes the flap 2 to the first position and pulls the air guide 3 to the avoidance position. The drive motor 4 drives the follower 5 to move in a second direction, whereby the follower 5 pulls the flap 2 to the second position and pushes the air guide 3 to the air guide position. The first direction and the second direction are opposite.

[0066] Based on the previous embodiment, in this embodiment, the follower 5 includes a follower plate 51, and a first follower arm 52 and a second follower arm 53 connected to the follower plate 51. The follower plate 51 is provided with a first connecting hole 511, a second connecting hole 512, and a third connecting hole 513 extending through it along its thickness. The first connecting hole 511, the second connecting hole 512, and the third connecting hole 513 are spaced apart. Optionally, the first connecting hole 511, the second connecting hole 512, and the third connecting hole 513 are distributed in a triangular pattern.

[0067] The output shaft of the drive motor 4 is arranged horizontally, and the driven plate 51 is arranged vertically. The output shaft of the drive motor 4 passes through the first connecting hole 511 to achieve a fixed connection between the drive motor 4 and the driven plate 51. The drive motor 4 is used to drive the driven plate 51 to rotate upward or downward with the output shaft of the drive motor 4 as the rotation axis. The driven plate 51 is rotatably connected to one end of the first driven arm 52 through the first connecting hole 511, and the other end of the first driven arm 52 is connected to the guide member 3; the driven plate 51 is rotatably connected to one end of the second driven arm 53 through the second connecting hole 512, and the other end of the second driven arm 53 is connected to the flap 2; wherein, the sides of the flap 2 and the guide member 3 are provided with connecting arms extending backward, the connecting arm of the guide member 3 is connected to the other end of the first driven arm 52, and the connecting arm of the flap 2 is connected to the other end of the second driven arm 53. The above solution is adopted to realize the linkage between the flap 2 and the guide member 3, so that the flap 2 and the guide member 3 are driven to move simultaneously by a drive motor 4, and in the relative movement stage, the movement trajectories of the flap 2 and the guide member 3 do not overlap, and there will be no motion interference problem.

[0068] In some embodiments, the flap 2 and the guide member 3 are connected to the first driven arm 52 and the second driven arm 53 respectively through their respective protruding arm structures.

[0069] like Figure 7-8 As shown, in some embodiments, the smoke hood further includes a bracket 7, which is fixed in the smoke collecting chamber 11; optionally, the bracket 7 is fixedly connected to the front shell wall 13. The flap 2 and the guide member 3 are both rotatably connected to the bracket 7 to achieve relative rotation with the shell 1.

[0070] like Figure 1-4As shown in FIG. 7 , as an optional embodiment, the fume hood further includes an oil cup 6 , which is disposed at the bottom of the housing 1 for receiving dripping dirty oil.

[0071] Based on the above embodiment, in this embodiment, the oil cup 6 is detachably connected to the bottom of the housing 1, and the oil cup 6 has an upward opening to enable the oil cup 6 to receive and store the dripping dirty oil.

[0072] like Figure 3 As shown, as an optional embodiment, the flap 2 rotates relative to the shell 1; when the flap 2 is in the first position, it covers the smoke inlet, and is used to guide the oil flowing into the smoke inlet to flow toward the oil cup 6; when the flap 2 is in the second position, it is arranged in the smoke collecting chamber 11, and is tilted to form a smoke guiding structure, which is used to guide the smoke flow to the smoke collecting chamber 11.

[0073] Based on the foregoing embodiments, in this embodiment, when the flap 2 is in the first position, the flow area of ​​the low-position smoke inlet 12 is very small, or even zero; when the flap 2 is in the second position, the flow area of ​​the low-position smoke inlet 12 is greater than the flow area when the flap 2 is in the first position.

[0074] When the flap 2 is in the first position, the outer wall of the flap 2 and the outer wall of the shell 1 form a guiding structure. The forearm of the oil cup 6 is arranged on the front side of the flap 2, and a gap is set between the flap 2. The oil on the outer wall of the shell 1 flows along the guiding structure through the gap between the forearm of the oil cup 6 and the flap 2, and finally falls into the oil cup 6, preventing the oil on the shell 1 from dripping onto the stove when the guide member 3 is in the non-guiding state, thereby polluting the kitchen.

[0075] When flap 2 is in the first position, it tilts backward and downward, positioned below the free end of the guide member 3. Oil dripping from the free end of the guide member 3 flows downward along the outer wall of flap 2, through the gap between the front arm of oil cup 6 and flap 2, and ultimately falls into oil cup 6, where it is collected and stored. Simultaneously, in the second position, flap 2 forms a suitable tilt angle, forming a bell-shaped diversion structure with the low-positioned smoke inlet 12. This ensures that smoke is more focused on the smoke source, with a smoother flow path and higher smoking efficiency.

[0076] Based on the same inventive concept, an embodiment of the present application provides a range hood, comprising the fume hood of any one of the aforementioned embodiments of the present application.

[0077] By applying the embodiments of the present application, at least the following beneficial effects can be achieved:

[0078] The smoke hood includes a flap 2 and a guide member 3, both of which can move relative to the shell 1. When the flap 2 moves to the first position, the guide member 3 is located in the avoidance position to avoid the flap 2. When the flap 2 is in the first position, the low-level smoke inlet 12 is closed; when the flap 2 is in the second position, the low-level smoke inlet 12 is opened, and the guide member 3 moves to the guide position to guide the oil flowing to the low-level smoke inlet 12 to flow toward the inside of the smoke collection chamber 11, so as to prevent the oil on the outer wall of the smoke hood from dripping onto the stove and polluting the kitchen, thereby reducing user cleaning and improving user experience.
