Description

Technical Field

[0001] The utility model relates to the technical field of range hood structural design, in particular to an oil collecting structure and a split range hood formed therefrom. Background Art

[0002] As people's living standards improve, users' requirements for kitchens continue to increase, and range hoods have basically become an indispensable kitchen appliance.

[0003] Currently, a split range hood has appeared on the market. The split range hood includes a fan module and a smoke hood module. The fan module and the smoke hood module are separately arranged, and the fan module and the smoke hood module are connected by a pipe. The smoke hood module is located above the stove. When the user is cooking, the smoke hood module can inhale the smoke generated during the cooking process, and the fan module discharges the smoke inhaled by the smoke hood module to the outside of the kitchen. After long-term use, a large amount of oil and dirt will be deposited inside the fan module, which is difficult to clean, so the user experience is poor.

[0004] Existing patent CN108266774A discloses a split-type range hood, wherein the fan includes a volute, a turbine, and a main fan motor. The fan is provided with a main air inlet, a secondary air inlet, and an air outlet. The size of the secondary air inlet can be fixed, so that the air intake ratio between the main air inlet and the secondary air inlet is fixed. The main air inlet accounts for the majority of the air intake, while a small portion of the air intake of the secondary air inlet is used to remove oil smoke that leaks from the smoke hood and rises into the upper space of the room. The secondary air inlet can also be equipped with a valve for adjusting the air flow rate of the secondary air inlet. The valve can be rotated to adjust the air intake of the secondary air inlet. During cooking, the secondary air inlet can be set to a small opening and low flow rate, with most of the air intake coming from the main air inlet. After cooking, the secondary air inlet is opened to a large opening and high flow rate, increasing the air intake of the secondary air inlet and delaying it for a certain period of time to remove residual oil smoke in the room. This technical solution removes oil stains by adding a secondary air inlet, which complicates the fan structure, and removing oil stains by exhausting air may result in the defect of incomplete oil stain removal.

[0005] The existing patent CN117553368A discloses that an oil collecting device is connected to the bottom of the smoke collecting module. The first oil hole can be connected to the smoke collecting module through an oil pipe. The oil collecting device can be arranged at the bottom of the smoke collecting module in a bowl shape or a long strip shape. The upper end of the oil pipe can be connected to the first oil hole, and the lower end of the oil pipe can be passed through the inside of the smoke collecting module. In this technical solution, the oil pollution is discharged through the oil pipe. The provision of the oil pipe increases the difficulty of design and installation, and once the oil pipe is damaged, it will make it difficult to remove the oil pollution; and the oil pipe is integrated inside the smoke collecting hood, which is difficult to repair and replace.

[0006] Therefore, it is necessary to design a structure for conveniently removing oil stains in the range hood. Utility Model Content

[0011] A drainage component, both ends of which are respectively connected to the oil outlet and the oil collecting piece, and the drainage component is located on the inner side wall of the fan module, the connecting pipe and the smoke hood module.

[0012] The drainage component in this application is located on the inner wall of the fan module, the connecting pipe and the smoke hood module. Specifically, it can be the inner wall of the fan module, the connecting pipe and the smoke hood module, or a drainage plate, drainage groove and other structures arranged on the inner wall of the fan module, the connecting pipe and the smoke hood module, to ensure that the drainage component in this application does not require additional settings, and only needs to be adapted and set according to the original range hood structure. In this way, the design and installation of the range hood can be simplified, the installation and maintenance costs of the range hood can be reduced, and the separation and recovery efficiency of liquid oil pollution can be improved.

[0013] In a preferred technical solution of the present invention, the guide assembly includes a first guide member located on the inner side wall of the fan module, a second guide member located on the inner side wall of the connecting duct, and a third guide member located on the inner side wall of the smoke hood module.

[0014] In the present application, the oil fume separation component is located at the center of the fan module, and the oil collecting component is located at the bottom of the fume hood module, that is, on the side away from the fan module. In order to realize the oil flow between the outlet and the oil collecting component, the drainage component needs to be located in the fan module, the connecting pipe and the drainage component at the same time. At the same time, the first drainage component, the second drainage component and the third drainage component are integrated on the inner wall of the fan module, the connecting pipe and the fume hood. The drainage component located on the inner wall does not occupy the internal area of the oil fume channel, that is, it does not affect the normal discharge of oil fume. At the same time, the shape of the inner wall of the fan module, the connecting pipe and the fume hood itself is used as the drainage component, which can simplify the structural design of the oil collection structure, eliminate the need to add unnecessary components, and facilitate design and installation.

[0015] In a preferred technical solution of the present invention, the first guide member includes a first guide plate and a guide portion, the guide portion is located at the bottom of the fan module, and the guide portion is a funnel-shaped structure, and the top cross-sectional area of the guide portion is larger than the bottom cross-sectional area; the first guide plate is located on one side of the oil outlet.

[0016] In this embodiment, the fan module specifically includes a fan cabinet. In order to facilitate the installation of the oil fume grading component, the cross-sectional area of the fan cabinet in the horizontal direction needs to be larger than the cross-sectional area of the connecting pipe. In order to achieve a smooth connection between the first guide member and the second guide member, the present application provides a guide portion at the bottom of the first guide plate. The shape of the guide portion, which is wide at the top and narrow at the bottom, can ensure smooth flow between the first guide plate and the second guide member, and can also be adapted to the shape of the connection between the fan and the connecting pipe. With the help of the guide portion, the first guide member and the second guide member can be smoothly connected, and at the same time, an orderly connection between the fan module and the connecting pipe can be achieved, avoiding the addition of additional connecting components.

[0017] In a preferred technical solution of the present invention, the oil fume separation component includes a centrifugal fan and a volute located outside the centrifugal fan, the oil fume separation component is located inside the fan cabinet, and the first guide plate is located on the inner wall of the volute.

[0018] In this embodiment, the first guide plate can specifically be the inner sidewall of the volute. After the centrifugal fan separates the oil smoke into gas and liquid, the liquid oil is thrown into the volute. The liquid oil first flows downward along the inner sidewall of the volute under the action of gravity and drips into the guide member. The guide member is wide at the top and narrow at the bottom to ensure smooth flow between the first guide plate and the second guide member. This application directly uses the inner sidewall of the volute as the first guide plate, eliminating the need for additional structures. The oil collection structure can be constructed by utilizing the gravity of the liquid oil, simplifying the design and installation of the oil collection structure.

[0019] In a preferred technical solution of the present invention, the top outer diameter of the connecting pipe is matched with the bottom inner diameter of the fan module, and the second flow-guiding member is located in the inner side wall of the connecting pipe.

[0020] In this embodiment, the second flow guide can specifically be the inner sidewall of the connecting pipe. After the liquid oil enters the connecting pipe through the flow guide, it continues to flow downward along the inner sidewall of the connecting pipe under the action of gravity until it enters the fume hood module. This application directly uses the inner sidewall of the connecting pipe as the second flow guide, eliminating the need for additional structures. The oil collection structure can be constructed by utilizing the gravity of the liquid oil, simplifying its design and installation.

[0021] In a preferred technical solution of the present invention, the third guide member includes a third guide plate and a guide plate, the third guide plate is located in the inner wall of the smoke hood module, and the guide plate is located at the bottom of the third guide plate, and the height of the guide plate near the third guide plate is greater than the height near the oil collecting member.

[0022] In this embodiment, the oil collecting piece is arranged at the bottom side position of the smoke hood module, and the third guide plate can specifically be the inner side wall of the smoke hood module. After the liquid oil passes through the inner side wall of the connecting pipe and enters the inner side wall of the smoke hood module, it continues to flow downward directly along the inner side wall of the smoke hood module under the action of gravity, and finally is guided into the oil collecting piece by the guide plate. The present application directly uses the inner side wall of the smoke hood module as the third guide plate, without the need for additional structure. The construction of the oil collecting structure can be realized by utilizing the gravity of the liquid oil, thereby simplifying the design and installation of the oil collecting structure. At the same time, since the oil collecting piece is only located at the bottom corner position of the smoke hood module, it is necessary to set a guide plate to guide the liquid oil on the inner side wall of the smoke hood module into the oil collecting piece. The guide plate is a structure arranged to be tilted downward toward the oil collecting piece, that is, the height of the guide plate near the third guide plate is greater than the height near the oil collecting piece; ensuring that the liquid oil can still fall into the oil collecting piece under the action of gravity in the guide plate.

[0023] The second object of the present application is to provide a split-type range hood, comprising an oil collection structure as described above.

[0024] In a preferred technical solution of the present invention, a first air inlet is provided at the bottom of the smoke hood module, a first air outlet is provided at the top of the smoke hood module, a second air inlet is provided at the bottom of the fan module, and a second air outlet is provided at the top of the fan module, and the first air outlet and the second air inlet are connected by a connecting pipe.

The drainage component in this application is located on the inner wall of the fan module, the connecting pipe and the smoke hood module. Specifically, it can be the inner wall of the fan module, the connecting pipe and the smoke hood module, or a drainage plate, drainage groove and other structures arranged on the inner wall of the fan module, the connecting pipe and the smoke hood module, to ensure that the drainage component in this application does not require additional settings, and only needs to be adapted and set according to the original range hood structure. In this way, the design and installation of the range hood can be simplified, the installation and maintenance costs of the range hood can be reduced, and the separation and recovery efficiency of liquid oil pollution can be improved.

[0029] The present invention also provides a split range hood including an oil collection structure, wherein the air inlet of the split range hood is used to extract oil fumes, and the oil fumes are separated into gaseous smoke and liquid oil in the oil fume separation component. The gaseous smoke is discharged from the exhaust component, and the liquid oil is drained into the oil collecting component by the drainage component, thereby effectively completing the classification and treatment of gaseous smoke and liquid oil. At the same time, the split range hood of the present application does not require the addition of additional components and structures, and only needs to be adapted and set according to the original range hood structure, which simplifies the design and installation of the range hood and reduces the installation and maintenance costs of the range hood.

[0042] Example 1

[0043] like Figures 1-6 As shown, an oil collecting structure comprises:

[0044] An oil fume separation assembly 111 located in the fan module 11, wherein the oil fume separation assembly 111 includes an oil outlet;

[0045] An oil collecting member 131 is located in the fume hood module 13; the fume hood module 13 is located below the fan module 11, and the fume hood module 13 is connected to the fan module 11 via a connecting pipe 12;

[0046] The drainage component has two ends connected to the oil outlet and the oil collecting member 131 respectively, and the drainage component is located on the inner side wall of the fan module 11, the connecting pipe 12 and the smoke hood module 13.

[0047] The oil collecting structure provided in the present application includes an oil fume separation component 111, an oil collecting piece 131 and a drainage component, wherein the oil fume separation component 111 is located in the fan module 11, the fan module 11 is connected to the smoke hood module 13 through the connecting pipe 12, the oil collecting piece 131 is located in the smoke hood module 13, and the smoke hood module 13 is arranged on the stove 15; the oil fume separation component 111 is used to realize the separation of gaseous smoke and liquid oil; since the position of the fan module 11 is relatively high, the liquid oil after separation is sprayed out from the oil outlet and falls into the drainage component under the action of gravity. The drainage component is also located in the inner side walls of the fan module 11, the connecting pipe 12 and the smoke hood module 13, and is used to guide the liquid oil to flow back to the oil collecting piece 131 for storage under the action of gravity. In the present application, the drainage component is located on the inner wall of the fan module 11, the connecting pipe 12 and the smoke hood module 13. Specifically, it can be the inner wall of the fan module 11, the connecting pipe 12 and the smoke hood module 13, or a drainage plate, drainage groove and other structures arranged on the inner wall of the fan module 11, the connecting pipe 12 and the smoke hood module 13, to ensure that the drainage component in the present application does not require additional settings, and only needs to be adapted and set according to the original range hood structure. In this way, the design and installation of the range hood can be simplified, the installation and maintenance costs of the range hood can be reduced, and the separation and recovery efficiency of liquid oil pollution can be improved.

[0048] The drainage components in this application are adapted and set according to the original range hood structure, including the following four situations:

[0049] (1) In the present application, the inner side walls of the fan module 11, the connecting pipe 12 and the smoke hood module 13 can be directly used as drainage components. Since the fan module 11, the connecting pipe 12 and the smoke hood module 13 are installed in a top-down order, the smoke hood module 13 is usually set above the stove 15, and the fan module 11 is set in the ceiling or suspended ceiling 16. Therefore, the inner side walls of the fan module 11, the connecting pipe 12 and the smoke hood module 13 themselves can be used as drainage components. The liquid oil after separation flows downward along the inner side walls of the fan module 11, the connecting pipe 12 and the smoke hood module 13 under the action of gravity until it flows back into the oil collecting part 131.

[0050] (2) The present application may provide drainage ducts, drainage plates, drainage grooves and other structures on the inner side walls of the fan module 11, the connecting pipe 12 and the smoke hood module 13 to drain the separated liquid oil. It should also be noted that the drainage components provided on the inner side walls of the fan module 11, the connecting pipe 12 and the smoke hood module 13 may be exposed to the oil smoke inside the fan module 11, the connecting pipe 12 and the smoke hood module 13, or may adopt a covering structure to isolate them from the oil smoke inside the fan module 11, the connecting pipe 12 and the smoke hood module 13.

[0051] (3) The drainage component in the present application can also be a combination of the above two. Specifically, it can be designed according to the specific structure of the range hood, based on forming the shortest oil path, and the inner wall of the fan module 11 or the connecting pipe 12 or the smoke hood module 13 in the local area is used as the drainage component, and drainage ducts, drainage plates, drainage grooves and other structures are set on the inner wall in the local area to form a complete oil collection structure.

[0052] Example 2

[0053] like Figures 1-6 As shown, an oil collecting structure comprises:

[0054] An oil fume separation assembly 111 located in the fan module 11, wherein the oil fume separation assembly 111 includes an oil outlet;

[0055] An oil collecting member 131 is located in the fume hood module 13; the fume hood module 13 is located below the fan module 11, and the fume hood module 13 is connected to the fan module 11 via a connecting pipe 12;

[0056] The drainage component has two ends connected to the oil outlet and the oil collecting member 131 respectively, and the drainage component is located on the inner side wall of the fan module 11, the connecting pipe 12 and the smoke hood module 13.

[0057] Specifically, such as Figure 2 As shown, the guide assembly includes a first guide member located on the inner side wall of the fan module 11 , a second guide member located on the inner side wall of the connecting duct 12 , and a third guide member located on the inner side wall of the smoke hood module 13 .

[0058] In the present application, the oil fume separation component 111 is located at the center of the fan module 11, and the oil collecting member 131 is located at the bottom of the fume hood module 13, that is, on the side away from the fan module 11. In order to realize the oil flow between the outlet and the oil collecting member 131, the drainage component needs to be located in the fan module 11, the connecting pipe 12 and the drainage component at the same time. At the same time, the first drainage member, the second drainage member and the third drainage member are integrated on the inner wall of the fan module 11, the connecting pipe 12 and the fume hood. The drainage member located on the inner wall does not occupy the internal area of the oil fume channel, that is, it does not affect the normal discharge of oil fume. At the same time, the shape of the inner wall of the fan module 11, the connecting pipe 12 and the fume hood itself is used as the drainage member, which can simplify the structural design of the oil collection structure, eliminate the need to add unnecessary components, and facilitate design and installation.

[0059] Specifically, such as Figure 3 As shown, the first guide member includes a first guide plate and a guide portion 113, the guide portion 113 is located at the bottom of the fan module 11, and the guide portion 113 is a funnel-shaped structure, and the top cross-sectional area of the guide portion 113 is larger than the bottom cross-sectional area; the first guide plate is located on one side of the oil outlet.

[0060] The first flow guide member located in the fan module 11 specifically includes a first flow guide plate located on the inner side wall of the fan module 11 and a flow guide portion 113 located at the bottom of the fan module 11. The flow guide portion 113 is a funnel-shaped structure, a truncated cone-shaped structure, a trapezoidal structure, or a cone-like structure, etc., and the top cross-sectional area of the flow guide portion 113 is larger than the bottom cross-sectional area, ensuring that the liquid oil flowing down the first flow guide plate is collected in the flow guide portion 113 and discharged into the connecting pipe 12. Figure 3-Figure 5 As shown, the positional relationship between the air guide portion 113 and the fan cabinet 114 is illustrated by taking the air guide portion 113 as a trapezoidal structure with a width at the top and a narrowness at the bottom as an example.

[0061] In this embodiment, the fan module 11 specifically includes a fan cabinet 114. In order to facilitate the installation of the oil fume grading component, the cross-sectional area of the fan cabinet 114 in the horizontal direction needs to be larger than the cross-sectional area of the connecting pipe 12. In order to achieve a smooth connection between the first guide member and the second guide member, the present application provides a guide portion 113 at the bottom of the first guide plate. The shape of the guide portion 113, which is wide at the top and narrow at the bottom, can ensure a smooth flow between the first guide plate and the second guide member, and can also be adapted to the shape of the connection between the fan and the connecting pipe 12. With the help of the guide portion 113, the first guide member and the second guide member can be smoothly connected, and at the same time, an orderly connection between the fan module 11 and the connecting pipe 12 can be achieved, avoiding the addition of additional connecting components.

[0062] Specifically, the oil fume separation component 111 includes a centrifugal fan and a volute 112 located outside the centrifugal fan. The oil fume separation component 111 is located inside the fan cabinet 114 , and the first guide plate is located on the inner wall of the volute 112 .

[0063] In this embodiment, the first guide plate can be specifically the inner wall of the volute 112. After the centrifugal fan separates the oil smoke into gas and liquid, the liquid oil is thrown into the volute 112. The liquid oil first flows downward along the inner wall of the volute 112 under the action of gravity and drips into the guide part 113. Figure 3 As shown. The wide top and narrow bottom shape of the guide portion 113 ensures smooth flow between the first guide plate and the second guide member. This application directly uses the inner wall of the volute 112 as the first guide plate, eliminating the need for additional structures. The oil collection structure is constructed by utilizing the gravity of the liquid oil, simplifying its design and installation.

[0064] Specifically, the outer diameter of the top of the connecting pipe 12 is matched with the inner diameter of the bottom of the fan module 11 , and the second flow-guiding member is located in the inner side wall of the connecting pipe 12 .

[0065] In this embodiment, the second flow guide member can specifically be the inner sidewall of the connecting pipe 12. After the liquid oil enters the connecting pipe 12 through the flow guide portion 113, it continues to flow downward directly along the inner sidewall of the connecting pipe 12 under the action of gravity until it enters the fume hood module 13. In this application, the inner sidewall of the connecting pipe 12 is directly used as the second flow guide member, eliminating the need for additional structures. The oil collection structure can be constructed by utilizing the gravity of the liquid oil, simplifying the design and installation of the oil collection structure.

[0066] Specifically, the third guide member includes a third guide plate and a guide plate. The third guide plate is located in the inner wall of the smoke hood module 13, and the guide plate is located at the bottom of the third guide plate. The height of the guide plate near the third guide plate is greater than the height near the oil collecting member.

[0067] In this embodiment, the oil collecting member 131 is disposed at the bottom side of the fume hood module 13, and the third guide plate can specifically be the inner side wall of the fume hood module 13. After the liquid oil passes through the inner side wall of the connecting pipe 12 and enters the inner side wall of the fume hood module 13, it continues to flow downward directly along the inner side wall of the fume hood module 13 under the action of gravity, and finally is guided by the guide plate into the oil collecting member 131. This application directly uses the inner side wall of the fume hood module 13 as the third guide plate, without the need for additional structures. The oil collecting structure can be constructed by utilizing the gravity of the liquid oil, thereby simplifying the design and installation of the oil collecting structure. At the same time, since the oil collecting piece 131 is only located at the bottom corner of the smoke hood module 13, a guide plate is required to guide the liquid oil on the inner wall of the smoke hood module 13 into the oil collecting piece 131. The guide plate is a structure that is tilted downward toward the oil collecting piece 131, that is, the height of the guide plate near the third guide plate is greater than the height near the oil collecting piece, ensuring that the liquid oil can still fall into the oil collecting piece 131 under the action of gravity in the guide plate.

[0068] As a specific embodiment, Figure 1 and Figure 6 As shown, the smoke hood module 13 includes a first smoke hood fume cabinet 132 and a second smoke hood fume cabinet 133, wherein the first smoke hood fume cabinet 132 is connected to the connecting pipe 12, and the first smoke hood fume cabinet 132 and the second smoke hood fume cabinet 133 form an L-shaped structure, and a first air inlet, that is, an exhaust port, is provided at the bottom of the opening of the L-shaped structure. A guide plate is provided at the bottom of the first smoke hood fume cabinet 132, and is used to collect and guide the liquid oil stains flowing down the inner wall of the first smoke hood fume cabinet 132 to the inner wall of the second smoke hood fume cabinet 133. In this structure, the third guide plate includes the inner wall of the first smoke hood fume cabinet 132 located above the guide plate and the inner wall of the second smoke hood fume cabinet 133 located below the guide plate. At the same time, the oil collecting member 131 can specifically be a structure such as an oil cup. The oil collecting member 131 is arranged at the bottom of the second fume hood wind cabinet 133 and is adapted to the cross-section of the second fume hood wind cabinet 133. Therefore, the liquid oil after passing through the guide plate can directly fall into the oil collecting member 131 along the inner side wall of the second fume hood wind cabinet 133. The function of the guide plate in this embodiment is to collect and guide the liquid oil in the inner side wall of the first fume hood wind cabinet 132 with a larger horizontal cross-section to the inner side wall of the second fume hood wind cabinet 133 with a smaller horizontal cross-section, so that the liquid oil in the inner side wall of the second fume hood wind cabinet 133 can directly drip into the oil collecting member 131.

[0069] Example 3

[0070] The difference between this embodiment and embodiment 2 is that:

[0071] In this embodiment, the first guide plate can be specifically a first drainage groove provided on the inner sidewall of the volute 112. Specifically, a first drainage groove is formed on the inner sidewall of the volute 112 to guide the separated liquid oil, and the liquid oil in the first drainage groove continues to fall under the action of gravity. As another preferred embodiment, a shielding plate can be provided on the outside of the first drainage groove to isolate the liquid oil from the oil fume passage, thereby preventing the suction force in the oil fume passage from affecting the liquid oil's gravity drop.

[0072] In this embodiment, the second drainage member can be specifically a second drainage groove provided on the inner sidewall of the connecting pipe 12, i.e., a second drainage groove is formed on the inner sidewall of the connecting pipe 12 to guide the liquid oil. Similarly, the liquid oil in the second drainage groove continues to fall under the action of gravity. As another preferred embodiment, a shielding plate can be provided outside the second drainage groove to isolate the liquid oil from the oil fume passage, preventing the suction force in the oil fume passage from affecting the gravity-induced fall of the liquid oil.

[0073] In this embodiment, the third diversion plate can specifically be a third diversion groove provided on the inner side wall of the fume hood module 13, that is, a third diversion groove is formed on the inner side wall of the fume hood module 13 to guide the liquid oil. Similarly, the liquid oil in the third diversion groove still falls under the action of gravity. As another preferred embodiment, a shielding plate can be provided on the outside of the third diversion groove to isolate the liquid oil from the oil fume channel, thereby preventing the suction force in the oil fume channel from affecting the liquid oil's gravity drop.

[0074] After the centrifugal fan separates the oil smoke into gas and liquid, the liquid oil is thrown out into the volute 112. The liquid oil first flows downward along the first drainage groove in the inner wall of the volute 112 under the action of gravity and drips into the guide part 113. The shape of the guide part 113 that is wide at the top and narrow at the bottom can ensure smooth flow between the first drainage groove and the second drainage groove. After the liquid oil passes through the guide part 113 and enters the connecting pipe 12, it continues to flow downward directly along the second drainage groove in the inner wall of the connecting pipe 12 under the action of gravity until it enters the smoke hood module 13. After the liquid oil enters the smoke hood module 13, it continues to flow downward along the third drainage groove on the inner wall of the smoke hood module 13 under the action of gravity, and finally is guided into the oil collecting part 131 through the guide plate.

[0075] Similar to Example 2, the third drainage groove includes a drainage groove provided in the side wall of the first fume hood cabinet 132 and a drainage groove located in the side wall of the second fume hood cabinet 133, which are connected by a guide plate.

[0076] In the present application, the guide plate can be a V-shaped structure arranged at the bottom of the first smoke collecting hood 132, and the opening of the V-shaped structure faces upward, such as Figure 2 As shown, the V-shaped guide plate is a downward-inclined structure from the left end to the right end, that is, the height of the guide plate near the third guide plate is greater than the height near the oil collecting part, ensuring that the liquid oil dripping from the first fume hood fume cabinet 132 located in the left area of the second fume hood fume cabinet 133 can flow along the guide plate into the second fume hood fume cabinet 133.

[0077] Example 4

[0078] like Figure 1-Figure 7 As shown, the present application provides a split-type range hood, comprising the oil collection structure described in Examples 1-3. At the same time, a first air inlet is provided at the bottom of the fume hood module 13, a first air outlet is provided at the top of the fume hood module 13, a second air inlet is provided at the bottom of the fan module 11, and a second air outlet is provided at the top of the fan module 11. The first air outlet and the second air inlet are connected by a connecting pipe 12. The second air outlet is connected to the exhaust component 14, which can be a structure such as an exhaust fan, for sucking the oil smoke entering from the first air inlet so that it moves toward the exhaust component 14. The oil smoke separation component 111 includes a centrifugal fan, and the centrifugal fan includes an air outlet and an oil outlet.

[0079] like Figure 1 As shown, the smoke hood module 13 in this application is located above the stove 15, and the first air inlet is set close to the stove position in the stove 15. The fan module 11 is located in the ceiling or the suspended ceiling 16,

[0080] like Figure 1 and Figure 6 As shown, the fume hood module 13 includes a first fume hood cabinet 132 and a second fume hood cabinet 133. The first fume hood cabinet 132 is connected to the connecting duct 12, and the first fume hood cabinet 132 and the second fume hood cabinet 133 form an L-shaped structure. A first air inlet is provided at the bottom of the opening of the L-shaped structure. A guide plate is provided at the bottom of the first fume hood cabinet 132 to collect and guide liquid oil pollution flowing down the inner wall of the first fume hood cabinet 132 to the inner wall of the second fume hood cabinet 133.

[0081] In the present application, the connecting pipe 12 is a retractable pipe used to connect the fan module 11 and the smoke hood module 13 at different heights and positions.

[0082] In the present application, the first fume hood and the second fume hood 132 and 133 form an L-shaped structure, and the opening of the L-shaped structure faces the human operating position, which is convenient for users to operate and observe various situations.

[0083] In the present application, the inner wall of the first smoke hood cabinet 132 is also provided with a partition, which is filled with a sound-absorbing material such as sponge to reduce the noise generated during the operation of the range hood. This position is close to the user, and the sound insulation treatment can improve the user's comfort.

[0084] The oil smoke generated during the user's cooking process enters the second smoke hood air cabinet 133 through the first air inlet, and then enters the fan module 11 through the first smoke hood air cabinet 132 and the connecting pipe 12. The oil smoke separation component 111 in the fan module 11 separates the gaseous smoke and liquid oil pollution. The separated gaseous smoke is discharged to the outside or into the flue through the exhaust component 14.

[0085] After the centrifugal fan separates the oil smoke into gas and liquid, the liquid oil is thrown out into the volute 112. The liquid oil first flows downward along the first guide plate in the inner wall of the volute 112 under the action of gravity and drips into the guide part 113. The shape of the guide part 113, which is wide at the top and narrow at the bottom, can ensure smooth flow between the first guide plate and the second guide plate. After the liquid oil passes through the guide part 113 and enters the connecting pipe 12, it continues to flow downward directly along the second guide plate in the inner wall of the connecting pipe 12 under the action of gravity until it enters the smoke hood module 13. After the liquid oil enters the smoke hood module 13, it continues to flow downward along the third guide groove on the inner wall of the smoke hood module 13 under the action of gravity, and finally is guided by the guide plate into the oil collecting part 131.

[0086] The utility model provides a split range hood including an oil collection structure, wherein the air inlet of the split range hood is used to extract oil fumes, and the oil fumes are separated into gaseous smoke and liquid oil in the oil fume separation component 111. The gaseous smoke is discharged from the exhaust component, and the liquid oil is drained into the oil collecting part 131 by the drainage component, thereby effectively completing the classification and treatment of the gaseous smoke and liquid oil. At the same time, the split range hood of the present application does not require the addition of additional components and structures, and only needs to be adapted and set according to the original range hood structure, which simplifies the design and installation of the range hood and reduces the installation and maintenance costs of the range hood.
