[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] The utility model provides a range hood, such as Figure 1-Figure 6 As shown, the range hood includes a smoke collecting chamber 10; the smoke collecting chamber 10 has a front side plate 20, and the front side plate 20 is provided with an upper air intake port 31 and a lower air intake port 32, and the upper air intake port 31 and the lower air intake port 32 are arranged at different heights; a filter support 41 and a filter 42 installed on the filter support 41 are arranged in the cavity of the smoke collecting chamber 10, and the filter 42 is located on the rear side of the upper air intake port 31; a first oil guide member 50 is also arranged in the cavity of the smoke collecting chamber 10, which is at least partially located in front of the filter 42, and the upper end of the first oil guide member 50 is connected to the filter support member 41 and is located below the filter 42, and the first oil guide member 50 is inclined forward and downward from the upper end of the first oil guide member 50 to guide the oil filtered by the front of the filter 42 to the inner surface 21 of the front side plate.

[0049] The oil smoke sucked by the upper air intake 31 flows through the filter 42, and the filter 42 accumulates oil. The oil on the filter 42 flows to the filter support 41 and flows downward. The oil on the front of the filter 42 can flow to the first oil guide 50 and flow downward along the first oil guide 50. Since the first oil guide 50 tilts forward and downward from the upper end of the first oil guide 50, the oil is guided to flow forward to the inner surface 21 of the front side plate, so as to collect and process the oil, avoid the direct dripping of the oil on the front side of the filter 42 and the filter support 41, and thus reduce the oil dripping from the lower air intake 32. Take the scenario where the user uses cleaning fluid to clean the range hood as an example. When the user cleans, the droplets and cleaning fluid on the filter 42 and the filter support 41 can be reliably guided to the inner surface 21 of the front side plate by the first oil guide 50, thereby reducing the risk of dripping from the lower air intake 32. The range hood reduces the cleaning difficulty for users and is conducive to improving the user experience.

[0050] by Figure 3 Taking the direction shown as an example, the left direction of the front-to-back direction 92 is forward, and the right direction of the front-to-back direction 92 is backward. The inner surface herein refers to the surface located in the smoke collecting chamber 10 or facing the smoke collecting chamber 10, and the outer surface herein refers to the surface away from the smoke collecting chamber 10 or located outside the smoke collecting chamber 10.

[0051] In one embodiment, the first oil guide 50 has a first oil collecting member 51 at the lower end, and the first oil collecting member 51 extends along the width direction 91 of the smoke collecting chamber 10, and at least one side of the first oil collecting member 51 has a first oil outlet 52. The first oil collecting member 51 guides the oil to flow along the width direction 91, so that the oil flows to both ends or one end of the width direction 91, so that the oil can flow downward from the side or the area close to the side, so as to avoid the lower air intake port 32. Since the lower air intake port 32 is generally arranged in the center, the first oil outlet 52 is arranged on at least one side of the first oil collecting member 51, so as to facilitate guiding the oil to the side, and can be guided through the side wall of the range hood, or through the channel between the side wall of the lower air intake port 32 and the side wall of the range hood, so as to reduce the risk of oil dripping from the lower air intake port 32.

[0052] The first oil collecting member 51 may be an oil collecting tank 511, and at least one end of the oil collecting tank 511 is provided with an opening or a hole, and the opening or the hole serves as a first oil outlet 52. The oil flowing to the oil collecting tank 511 flows along the oil collecting tank 511, and is thereby guided to the end of the smoke collecting chamber 10 in the width direction 91, and flows out through the first oil outlet 52. The oil collecting tank 511 collects the oil, and can play a buffering role, so that the oil flows to at least one side after buffering, thereby avoiding direct diversion and causing oil splashing, especially when the user uses cleaning fluid for cleaning, avoiding a large amount of cleaning fluid accompanying the oil and causing splashing. Specifically, the oil collecting tank 511 may extend substantially along the width direction 91 of the smoke collecting chamber 10.

[0053] Furthermore, if Figure 2 and Figure 4 As shown, the oil collecting groove 511 is formed by bending the first oil guide member 50 in a direction away from the lower air intake port 32. The oil can flow directly into the oil collecting groove 511 along the upper surface of the first oil guide member 50. Moreover, the oil collecting groove 511 and the first oil guide member 50 are an integral structure, which is conducive to reducing the assembly process and saving costs.

[0054] The oil collecting tank 511 may also be a non-integrated structure with the first oil guiding member 50. For example, the oil collecting tank 511 and the first oil guiding member 50 are split structures. The oil collecting tank 511 is arranged below the lower end of the first oil guiding member 50 and can be fixed in position by the front side plate 20 or other components. The oil on the first oil guiding member 50 can fall into the oil collecting tank 511 after dripping from its lower end.

[0055] In one embodiment, the first oil collecting member 51 is connected to the inner surface 21 of the front side plate. After the oil on the first oil collecting member 51 flows out from the first oil outlet 52, it can flow to the inner surface 21 of the front side plate and flow downward along the inner surface 21 of the front side plate, which is conducive to making the oil flow more smoothly and steadily and avoiding dripping and splashing of the oil after flowing out from the first oil outlet 52.

[0056] The first oil collecting component 51 is connected to the inner surface 21 of the front side plate. Specifically, the first oil collecting component 51 is in direct contact with the inner surface 21 of the front side plate, so that the oil flowing out of the first oil outlet 52 can flow to the inner surface 21 of the front side plate. However, the first oil collecting component 51 and the front side plate 20 can be fixedly connected by a fixed structure, or a fixed structure may not be provided; or, the first oil collecting component 51 is not in direct contact with the inner surface 21 of the front side plate, and a small gap may be provided between the two or they may be connected by other connecting parts, as long as the oil flowing out of the first oil outlet 52 can flow to the inner surface 21 of the front side plate.

[0057] In another embodiment, there is a gap 53 between the first oil collecting member 51 and the inner surface 21 of the front side plate. When the gap 53 is large, the oil flowing out of the first oil outlet 52 may not pass through the inner surface 21 of the front side plate, for example, the oil flowing out of the first oil outlet 52 may directly drip into the oil cup 82 below; or, it may be guided to the oil cup 82 through other guide members. When the gap 53 is large, the oil flowing out of the first oil outlet 52 may also pass through other guide members before flowing to the inner surface 21 of the front side plate.

[0058] When the gap 53 is small, after the oil flows out of the first oil outlet 52, it can drip a shorter distance to the inner surface 21 of the front side plate and continue to flow downward along the inner surface 21 of the front side plate. Alternatively, other guide members can be provided to guide the oil flowing out of the first oil outlet 52 to the inner surface 21 of the front side plate.

[0059] There is a gap 53 between the first oil collecting member 51 and the inner surface 21 of the front side plate, so that during assembly, it is not necessary to ensure that the first oil collecting member 51 is in contact with the inner surface 21 of the front side plate, thereby reducing the assembly accuracy requirements, which is conducive to reducing assembly difficulty and saving costs.

[0060] The structural form of the first oil collecting member 51 is not limited to the oil collecting groove 511. For example, the first oil collecting member 51 includes a guide protrusion arranged on the inner surface 21 of the front side plate, and the guide protrusion is located below the lower end of the first oil guiding member 50. The guide protrusion extends along the width direction 91 of the smoke collecting chamber 10 as a whole, and the guide protrusion extends from one end to the other end of the width direction 91 of the smoke collecting chamber 10 while tilting downward, or the guide protrusion extends from the middle to both ends while tilting downward, and the lower end of the guide protrusion serves as the first oil outlet 52. The oil on the first oil guiding member 50 drips from its lower end and falls onto the upper surface of the guide protrusion, and flows along the guide protrusion to the end of the width direction 91 of the smoke collecting chamber 10, so as to guide the oil to flow downward from the side or the area close to the side, thereby avoiding the lower air intake port 32.

[0061] In another embodiment, the lower end of the first oil guide member 50 is connected to the inner surface 21 of the front side plate, and the lower end of the first oil guide member 50 and the inner surface 21 of the front side plate together form an oil collecting groove 511, and at least one side of the oil collecting groove 511 has a first oil outlet 52. The oil collecting groove 511 generally extends along the width direction 91 of the smoke collecting chamber 10, and the oil on the upper surface of the first oil guide member 50 flows to the lower end of the first oil guide member 50, that is, enters the oil collecting groove 511, and the oil collecting groove 511 guides the oil to flow toward the end of the width direction 91 of the smoke collecting chamber 10. In this embodiment, the lower end of the first oil guide member 50 does not need to be bent, which reduces the manufacturing difficulty of the first oil guide member 50.

[0062] Preferably, the lower end of the first oil guide member 50 is in direct contact with the inner surface 21 of the front side plate. The lower end of the first oil guide member 50 may be fixedly connected to the front side plate 20 via a fixing structure, or may not be provided with a fixing structure.

[0063] In one embodiment, a second oil collecting member 60 is provided on the inner surface 21 of the front side plate. The second oil collecting member 60 extends along the width direction 91 of the smoke collecting chamber 10. The second oil collecting member 60 is located below the first oil guide member 50 and is used to collect the oil condensed on the lower surface of the first oil guide member 50. At least one side of the second oil collecting member 60 has a second oil outlet 61. The first oil guide member 50 is inclined forward and downward from the upper end of the first oil guide member 50. The oil smoke sucked by the lower air intake port 32 will contact the lower surface of the first oil guide member 50 and condense during the upward flow, resulting in the accumulation of oil on the lower surface of the first oil guide member 50. If the oil on the lower surface of the first oil guide member 50 drips directly, it may drip into the lower air intake port 32, affecting the user experience. In this embodiment, after the oil on the lower surface of the first oil guide member 50 leaves the first oil guide member 50, it can enter the second oil collecting member 60. The second oil collecting member 60 guides the oil to flow along the width direction 91 of the smoke collecting chamber 10. After the oil flows out from the second oil outlet 61, it can flow downward from the area close to the end of the smoke collecting chamber 10 in the width direction 91 so as to avoid the lower air intake port 32.

[0064] Furthermore, the lower end of the first oil guide member 50 is connected to the inner surface 21 of the front side plate or the lower end of the first oil guide member 50 is arranged close to the inner surface 21 of the front side plate, and the oil condensed on the lower surface of the first oil guide member 50 can flow into the second oil collecting member 60 through the inner surface 21 of the front side plate. In this way, the oil flowing along the lower surface of the first oil guide member 50 to the lower end of the first oil guide member 50 flows along the inner surface 21 of the front side plate after leaving the first oil guide member 50, which can reduce the oil dripping from the lower end of the first oil guide member 50 and make the oil flow more smoothly.

[0065] The lower end of the first oil guide member 50 is close to the inner surface 21 of the front side plate. Specifically, there is a small gap between the lower end of the first oil guide member 50 and the inner surface 21 of the front side plate. Due to the small gap, the oil leaving the lower end of the first oil guide member 50 can flow to the inner surface 21 of the front side plate.

[0066] like Figure 2 and Figure 7 As shown, the second oil collecting member 60 extends along the width direction 91 of the smoke collecting chamber 10, and at the same time extends a distance along the front-to-back direction 92 of the smoke collecting chamber 10, so as to receive the oil dripping from the lower surface of the first oil guide member 50 or flowing downward along the inner surface 21 of the front side plate. Preferably, the second oil collecting member 60 is connected to the inner surface 21 of the front side plate. The second oil collecting member 60 can be groove-shaped itself, or it can form a groove together with the inner surface 21 of the front side plate.

[0067] In one embodiment, the second oil collecting member 60 extends downward along the inner surface 21 of the front side plate to the upper end of the lower air intake port 32, and at the upper end of the lower air intake port 32, extends downward and toward the interior of the smoke collecting chamber 10 to form a second oil guiding member 62. After the oil on the front side plate 20 flows to the upper end of the lower air intake port 32, it can flow toward the interior of the smoke collecting chamber 10 along the second oil guiding member 62 to guide the oil into the interior of the smoke collecting chamber 10, thereby preventing the oil on the front side plate 20 from dripping directly from the lower air intake port 32. The second oil guiding member 62 and the second oil collecting member 60 are an integrated structure, which can reduce the assembly process and save costs. Specifically, as Figure 7 As shown, the second oil guide member 62 includes a first extension section 621 , and the first extension section 621 extends downward and toward the interior of the smoke collecting chamber 10 .

[0068] Furthermore, the second oil collecting member 60 extends downward along the inner surface 21 of the front side plate to the upper end of the lower air inlet 32, and after being bent forward along the upper end of the lower air inlet 32 ​​to the outer surface 22 of the front side plate, extends downward and toward the inside of the smoke collecting chamber 10 to form a second oil guiding member 62. The second oil guiding member 62 extends to the outer surface 22 of the front side plate, so that the oil condensed on the outer surface 22 of the front side plate can flow smoothly to the second oil guiding member 62, and continue to flow toward the inside of the smoke collecting chamber 10 along the second oil guiding member 62.

[0069] Specifically, Figure 7 As shown, the second oil guide 62 includes a first extension section 621 and a second extension section 622, the second extension section 622 extends from the inner surface 21 of the front side plate to the outer surface 22 of the front side plate, the first extension section 621 is connected to an end of the second extension section 622 close to the outer surface 22 of the front side plate, and the oil on the outer surface 22 of the front side plate can flow to the intersection of the first extension section 621 and the second extension section 622 and continue to flow downward along the first extension section 621. Preferably, the second extension section 622 extends forwardly along the lower end surface of the front side plate 20.

[0070] An oil cup 82 is provided at the lower part of the smoke collecting chamber 10, and the oil on the second oil guide member 62 can enter the oil cup 82 after leaving the lower end thereof. When the vertical projection of the lower end of the second oil guide member 62 at least partially overlaps with the oil cup 82, the oil dripping from the lower end of the second oil guide member 62 can directly fall into the oil cup 82.

[0071] In one embodiment, a condensation plate 80 extending obliquely upward toward the inside of the smoke collecting chamber 10 is provided at the lower end of the lower air inlet 32, and the lower end of the condensation plate 80 is located above the oil cup 82, and the second oil guide 62 and the projection of the condensation plate 80 on the horizontal plane at least partially overlap. The oil dripping from the lower end of the second oil guide 62 first falls on the condensation plate 80 and then flows along the condensation plate 80 to the oil cup 82, which is conducive to the smooth and stable flow of the oil into the oil cup 82. In this embodiment, the vertical projection of the lower end of the second oil guide 62 does not have to overlap with the oil cup 82.

[0072] Furthermore, the front surface of the condensation plate 80 is used to guide the oil of the second oil guide member 62 to the oil cup 82, and the rear surface of the condensation plate 80 is provided with a support member 81, and the support member 81 is connected to the back plate 11 of the smoke collecting chamber 10. The front surface of the condensation plate 80 extends toward the inside of the smoke collecting chamber 10 and tilts upward, and the front surface of the condensation plate 80 and the projection of the condensation plate 80 on the horizontal plane at least partially overlap. After the oil of the second oil guide member 62 drips onto the front surface of the condensation plate 80, it flows downward along the front surface of the condensation plate 80 into the oil cup 82. The condensation plate 80 is connected to the back plate 11 of the smoke collecting chamber 10 through the support member 81, which improves the stability of the overall structure.

[0073] In one embodiment, a third oil guide 70 having a smoke passage is further provided in the smoke collecting chamber 10 and is at least partially located at the rear side of the filter 42. The upper end of the third oil guide 70 is connected to the filter support 41 and is located below the filter 42. The third oil guide 70 extends from front to rear and downward to guide the oil on the rear surface of the filter 42 to the rear back plate 11 of the smoke collecting chamber 10. The oil on the rear surface of the filter support 41 can flow to the third oil guide 70 and flow downward and backward along the third oil guide 70 to flow to the rear back plate 11 of the smoke collecting chamber 10, so as to prevent the oil on the rear surface of the filter support 41 from directly dripping from the lower end of the filter support 41.

[0074] The airflow of the lower air inlet 32 ​​can flow upward through the smoke passage. Specifically, the smoke passage may include a smoke flow hole 72. Figure 4 and Figure 5As shown, the third oil guide member 70 is provided with a guide groove 71, and the oil on the rear surface of the filter support member 41 can flow into the guide groove 71 and flow along the guide groove 71 to the back plate 11 of the smoke collecting chamber 10. Preferably, the lower end of the third support member 81 is connected to the back plate 11. More preferably, the lower end of the third support member 81 is fixedly connected to the back plate 11 through a fixing structure to improve the structural firmness.

[0075] The first oil guide member 50, the third oil guide member 70 and the filter support member 41 may be formed and connected in various ways:

[0076] In one embodiment, the third oil guide member 70 is integrally formed with the filter support member 41, and the filter support member 41 extends by bending downward and backward to form the third oil guide member 70, which is beneficial for the oil on the rear surface of the filter support member 41 to flow smoothly to the third oil guide member 70, reduces the assembly process, and improves the stability of the overall structure.

[0077] In one embodiment, the first oil guide member 50, the third oil guide member 70 and the filter support member 41 are integrally formed, which is beneficial for the oil on the front surface of the filter support member 41 to flow smoothly to the first oil guide member 50, and the oil on the rear surface of the filter support member 41 to flow smoothly to the third oil guide member 70, and reduces the assembly process and improves the stability of the overall structure.

[0078] In one embodiment, if Figure 5 As shown, the first oil guide member 50 is not integrally connected to the filter support member 41, and the third oil guide member 70 is integrally formed with the filter support member 41, so as to facilitate the installation of the filter support member 41, the third oil guide member 70 and the first oil guide member 50 into the smoke collecting chamber 10, thereby reducing the difficulty of assembly. In another embodiment, the first oil guide member 50, the third oil guide member 70 and the filter support member 41 are not integrally connected, and the three are installed separately.

[0079] The one-piece forming can be specifically carried out by bending, metal stamping or welding.

[0080] The non-integrated connection may specifically include: connecting the two by screws, abutting or bonding, etc.; or, there is a small gap between the two, and it is ensured that the oil in the filter support 41 can flow to the first oil guide member 50 or the third oil guide member 70.

[0081] In one embodiment, the front side panel 20 of the smoke collecting chamber 10 is an inclined panel at a preset angle to the vertical direction, such as Figure 1 and Figure 2As shown, the front side plate 20 extends downward from top to bottom and tilts backward at the same time. Preferably, the range hood is an ultra-thin range hood, and the upper air inlet 31 and the lower air inlet 32 ​​are arranged on the inclined panel, which is conducive to the upper air inlet 31 and the lower air inlet 32 ​​to cooperate to improve the oil fume suction effect. At the same time, because the upper air intake 31 and the lower air intake 32 are both arranged on the inclined panel, the upper air intake 31 protrudes forward more than the lower air intake 32. Compared with the pulling effect of the lower air intake 32 on the oil smoke, the upper air intake 31 is mainly used to collect a large amount of oil smoke. Therefore, the upper air intake 31 has a greater demand for guiding the condensed oil. If the oil filtered by the filter on the rear side of the upper air intake 31 cannot be effectively guided, it will drip out from the upper air intake 31 and the lower air intake 32. Through the first oil guide member 50 of the embodiment of the utility model, the oil at the upper air intake 31 can be more effectively guided downward, and the risk of the downwardly guided oil dripping from the lower air intake 32 can be reduced.

[0082] Furthermore, the upper portion of the front side plate 20 has an inner bending portion 24, which extends toward the inside of the smoke collecting chamber 10 and tilts downward to connect with the filter support 41, and the oil can flow along the inner bending portion 24 to the front surface of the filter support 41, and continue to flow to the first oil guide 50. Preferably, the inner bending portion 24 is fixed to the front surface of the filter support 41 to connect the front side plate 20 and the filter support 41 together, thereby improving the firmness of the overall structure; a third oil outlet 25 can be provided on the inner bending portion 24, and the oil on the inner bending portion 24 can flow to the front surface of the filter support 41 through the third oil outlet 25.

[0083] In one embodiment, the smoke collecting chamber 10 is a thin smoke collecting chamber, and the projection of the filter 42 or the filter support 41 and the lower air intake port 32 on the horizontal plane at least partially overlap. Since it is a thin smoke collecting chamber, the distance between the upper air intake port 31 and the lower air intake port 32 in the front-to-back direction is relatively small, and the filter 42 is located at the rear side of the upper air intake port 31. A certain distance is maintained between the filter 42 and the upper air intake port 31 to ensure that the oil smoke is fully filtered, and the distance between the two is small so that the filter 42 is close to the upper air intake port 31 to ensure that the oil smoke at the upper air intake port 31 is filtered in time. Therefore, there is often an overlapping area between the filter 42 and the lower air intake port 32, and oil is likely to drip directly out of the range hood in the overlapping area. The first oil guide 50 in the embodiment can effectively guide the oil in the overlapping area. Figure 6As shown, a preset spacing 33 is provided between the side edge of the lower air inlet 32 ​​and the side edge 23 of at least one side of the front side plate 20 in the width direction 91, so that the oil above the lower air inlet 32 ​​can flow along the inner surface 21 of the front side plate to the bottom of the lower air inlet 32. Since the lower air inlet 32 ​​mainly plays a pulling role, the opening area cannot be too large. In this embodiment, a preset spacing is provided between the side edge of the lower air inlet and the side edge of at least one side of the front side plate 20 in the width direction 91 to reduce the opening area of ​​the lower air inlet 32 ​​and ensure that the lower air inlet 32 ​​has sufficient suction. At the same time, the preset spacing 33 is cleverly used as a flow channel for the oil.

[0084] The first oil collecting member 51 guides the oil to the end of the smoke collecting chamber 10 in the width direction 91. The preset spacing 33 is located at the end of the smoke collecting chamber 10 in the width direction 91. The inner surface 21 of the front side plate at the preset spacing 33 allows the oil to flow downward, thereby ensuring that the oil smoke can continuously flow downward along the inner surface 21 of the front side plate to avoid the lower air intake port 32, thereby preventing the oil from dripping from the upper edge of the lower air intake port 32.

[0085] Specifically, the width of the lower air inlet 32 ​​is smaller than the width of the front side plate 20, so that there is a preset distance 33 between the lower air inlet 32 ​​and the side edge 23 of the front side plate 20. Figure 6 As shown, along the width direction 91, at least one end of the first oil collecting member 51 extends to the outside of the lower air intake port 32, and at least one end of the second oil collecting member 60 also extends to the outside of the lower air intake port 32, so that the first oil outlet 52 and the second oil outlet 61 are both located on the outside of the lower air intake port 32, thereby ensuring that the oil flowing out of the first oil outlet 52 and the second oil outlet 61 can avoid the lower air intake port 32 during the downward flow.

[0086] The above are only several embodiments of the present invention. Those skilled in the art can make various changes or modifications to the embodiments of the present invention based on the contents disclosed in the application documents without departing from the spirit and scope of the present invention.
