Detailed Implementation

[0055] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings.

Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0058] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0059] Unless otherwise stated, the term "multiple" means two or more.

[0060] As can be seen from the background technology, a range hood typically includes a smoke collection box and a main box located above the smoke collection box. The main box contains a smoke extraction fan, and the air inlet of the smoke extraction fan is connected to the smoke collection box. The smoke collection box has a smoke inlet facing the cooking area below. The smoke extraction fan can draw oil fumes and other pollutants into the range hood through the smoke inlet.

[0061] During the extraction of cooking fumes, due to temperature changes inside the range hood and the characteristics of the fumes themselves, the fumes gradually condense inside the collection box and main chamber. The condensed oil droplets accumulate on the surfaces of various components of the range hood, such as the volute of the exhaust fan and the inner wall of the main chamber.

[0062] For the main housing and the lower part of the volute near the smoke inlet, when grease accumulates to a certain extent, under the vibration or airflow disturbance during the operation of the range hood, oil droplets on the grease may fall off, flow along the internal channel, and eventually drip from the smoke inlet onto the cooking countertop, causing inconvenience to the user.

[0063] To address the aforementioned problems, this application provides a smoke collection device and a range hood. The smoke collection device includes a housing with a smoke chamber having a downward-facing smoke inlet. An oil-collecting component is disposed within the smoke chamber, vertically spaced from the smoke inlet. The orthographic projection of the oil-collecting component on a horizontal plane covers the orthographic projection of the smoke inlet on a horizontal plane. The oil-collecting component is used to collect oil droplets dripping from above the smoke inlet. By providing an oil-collecting component within the smoke chamber, the component can effectively collect oil droplets dripping from the smoke chamber to the smoke inlet above the smoke inlet. Furthermore, the horizontal projection area of ​​the oil-collecting component is larger than that of the smoke inlet, increasing its effective oil-collecting range. Oil droplets dripping towards the smoke inlet can be caught by the oil-collecting component, effectively preventing these droplets from dripping onto the cooking countertop through the smoke inlet.

[0064] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0065] Combination Figures 1 to 3 As shown, one embodiment of this application provides a range hood, including a main box 900 and a smoke collection device. The main box 900 is disposed above the housing 100, and a smoke extraction fan (not shown in the figure) is disposed inside the main box 900.

[0066] The smoke collection device includes a housing 100, which has a smoke chamber 101. The smoke chamber 101 has a downward-facing smoke inlet 141. The air inlet of a smoke extraction fan is connected to the smoke chamber 101, and the air outlet of the smoke extraction fan can be connected to an exhaust duct. The smoke inlet 141 faces the cooking area. The fumes generated in the cooking area can enter the smoke chamber 101 through the smoke inlet 141 under the suction effect of the smoke extraction fan, and then be discharged through the exhaust duct.

[0067] During the process of the range hood extracting fumes, the fumes condense on the inner wall of the main chamber 900 and the surface of the volute of the exhaust fan, forming oil droplets. For the part of the main chamber 900 and the lower end of the volute near the smoke inlet 141, the oil droplets on its surface may drip into the smoke chamber 101 and then drip onto the cooking countertop through the smoke inlet 141.

[0068] To address the issue of oil droplets falling from the smoke inlet 141 onto the cooking countertop, an oil collecting component 200 is installed inside the smoke chamber 101 of the smoke collection device. Vertically, the oil collecting component 200 is spaced apart from the smoke inlet 141, and the orthographic projection of the oil collecting component 200 on the horizontal plane can cover the orthographic projection of the smoke inlet 141 on the horizontal plane. The oil collecting component 200 is used to collect oil droplets dripping from above the smoke inlet 141.

[0069] By providing an oil-collecting component 200 inside the smoke chamber 101, the oil-collecting component 200 can effectively collect oil droplets dripping from the smoke chamber 101 to the smoke inlet 141 above the smoke inlet 141. Furthermore, the horizontal projected area of ​​the oil-collecting component 200 is larger than that of the smoke inlet 141, increasing the effective oil-collecting range of the oil-collecting component 200. Oil droplets dripping towards the smoke inlet 141 can be caught by the oil-collecting component 200, effectively preventing these oil droplets from dripping onto the cooking countertop through the smoke inlet 141.

[0070] Combination Figure 3 and Figure 4 As shown, another aspect of this application provides a smoke collection device, including a housing 100, the housing 100 being provided with a smoke chamber 101, the smoke chamber 101 having a downward-facing smoke inlet 141; an oil receiving component 200 is provided inside the smoke chamber 101, the oil receiving component 200 being spaced apart from the smoke inlet 141 in the vertical direction, the orthographic projection of the oil receiving component 200 on the horizontal plane covering the orthographic projection of the smoke inlet 141 on the horizontal plane, the oil receiving component 200 being used to receive oil droplets dripping from above the smoke inlet 141.

[0071] Combination Figure 1 As shown, the range hood has a front and rear side arranged opposite to each other, a left and right side arranged opposite to each other, and a top and bottom arranged opposite to each other.

[0072] The front side of the range hood (the side facing away from the Y-axis of center 1) faces the user and has a control panel for operation. The rear side of the range hood (the side facing the Y-axis of center 1) can be used to connect to the surface to which the range hood will be installed.

[0073] Taking the user's perspective facing the front of the range hood as an example, the left side of the range hood (facing away) Figure 1 The side facing the center (X-axis) is closer to the user's left, while the right side of the range hood (facing the center) is closer to the user's right. Figure 1 The top of the range hood (facing the X-axis) is closer to the user's right side. Figure 1 The side facing Z (in the middle) can be used to connect to the installation surface of the range hood. The smoke collection device is located at the bottom of the range hood (away from the center). Figure 1 On the Z-shaped side, the smoke inlet 141 can face the cooking area below. As cooking fumes rise naturally during cooking, they are more easily drawn into the smoke chamber 101.

[0074] By providing an oil collecting device 200 inside the smoke chamber 101, and with the oil collecting device 200 located above the smoke inlet 141, the oil collecting device 200 can effectively collect oil droplets dripping from the upper part of the smoke chamber 101 to the smoke inlet 141, preventing these oil droplets from dripping onto the cooking countertop through the smoke inlet 141.

[0075] However, if the oil receiving part 200 is in close proximity to the smoke inlet 141, it may interfere with the flow path of the oil fumes, causing the oil fumes to be obstructed when entering the smoke inlet 141. By setting a gap between the oil receiving part 200 and the smoke inlet 141, the interference of the oil receiving part 200 on the flow path of the oil fumes can be reduced, ensuring that the oil fumes can be smoothly drawn into the smoke inlet 141.

[0076] By increasing the horizontal projected area of ​​the oil receiving component 200, the effective oil receiving range of the oil receiving component 200 is increased. Oil droplets dripping toward the smoke inlet 141 can be caught by the oil receiving component 200, which can ensure that the oil droplets will not bypass the oil receiving component 200 and directly enter the smoke inlet 141.

[0077] Specifically, the smoke collection device provided in this application embodiment, by setting an oil receiving component 200 in the smoke chamber 101 and ensuring that its horizontal projection covers the smoke inlet 141, can effectively collect oil droplets dripping from inside the smoke chamber 101 to the smoke inlet 141, preventing oil droplets from dripping onto the cooking countertop through the smoke inlet 141. This not only improves the ease of use of the range hood but also reduces the user's cleaning burden and enhances the overall user experience.

[0078] Combination Figures 5 to 7 As shown, in some embodiments, the edge of the oil receiving member 200 is provided with a first oil blocking edge 210, which extends upward; the oil receiving member 200 is provided with a first channel 220, which is used to discharge oil from the oil receiving member 200.

[0079] Understandably, when oil droplets accumulate on the oil receiving part 200, they may flow on the oil receiving part 200 due to external factors (such as vibration, airflow changes) or excessive oil droplet accumulation. By setting a first oil-blocking edge 210 at the edge of the oil receiving part 200, oil droplets can be prevented from overflowing, thereby ensuring that the oil droplets are confined within the range of the oil receiving part 200.

[0080] After oil droplets accumulate on the oil receiving device 200, they need to be drained in a timely manner to avoid overflow or affecting the continued use of the oil receiving device 200. By setting the first channel 220 in the oil receiving device 200, a clear oil drainage path is provided, allowing oil droplets to flow smoothly to the designated collection or discharge area, thereby maintaining the cleanliness and effectiveness of the oil receiving device 200.

[0081] For example, a flange can be formed on the edge of the oil receiving part 200 by bending sheet metal to serve as the first oil blocking edge 210, which has the characteristics of simple processing technology and easy implementation.

[0082] In some embodiments, the top of the oil receiving member 200 has an oil guiding surface 230, and the first end of the oil guiding surface 230 is close to the smoke inlet 141 relative to the second end of the oil guiding surface 230; the first channel 220 is close to the first end of the oil guiding surface 230.

[0083] The top surface of the oil receiving component 200 can be configured as an oil guiding surface 230, which can be an inclined surface with a lower first end and a higher second end. The inclined oil guiding surface 230 can guide the oil droplets to flow along the inclined surface to the lower end (i.e., the first end) for discharge.

[0084] The oil guiding surface 230 of the oil receiving component 200 can be a straight surface or an arc surface, as long as the lowest point of the oil guiding surface 230 is located at the first end of the oil guiding surface 230. This embodiment of the application does not impose any restrictions on this. The surface of the oil guiding surface 230 can also be provided with a guide groove to promote the smooth flow of oil droplets to the first channel 220, so that the oil droplet collection and discharge process can proceed smoothly.

[0085] The first channel 220 is located near the first end of the oil guiding surface 230, which can be located at the lowest point of the oil guiding surface 230. This allows oil droplets to smoothly enter the channel when they reach the lowest point of the oil guiding surface 230, thereby achieving efficient oil droplet discharge and reducing the accumulation of oil droplets on the oil guiding surface 230.

[0086] For example, the first channel 220 may be a plurality of through holes formed on the oil guide.

[0087] In some embodiments, the orthographic projection of the first channel 220 onto the horizontal plane is located outside the orthographic projection of the flue gas inlet 141 onto the horizontal plane, which can reduce the intersection of oil droplets with the flue gas inlet 141 during the discharge process.

[0088] The horizontal projection of the first channel 220 is set outside the horizontal projection of the smoke inlet 141, so that when oil droplets are discharged through the first channel 220, they can avoid the smoke inlet 141. This setting can prevent oil droplets from re-entering the smoke inlet 141 during the discharge process, thereby preventing oil droplets from falling onto the cooking countertop.

[0089] Combination Figure 3 and Figure 4 As shown, in some embodiments, the housing 100 includes a front panel 150, a rear panel 160, and two side panels 170 disposed between the front panel 150 and the rear panel 160. The front panel 150, the rear panel 160, and the two side panels 170 can be configured to form a receiving area, which is used to form a smoke chamber 101.

[0090] Combination Figure 5As shown, in some embodiments, the housing 100 includes a front air guide 110, a rear air guide 120, and two side air guides 130; the front air guide 110 and the rear air guide 120 are arranged parallel to each other and opposite to each other, the two side air guides 130 are arranged opposite to each other, one end of the side air guide 130 is connected to the front air guide 110, and the other end of the side air guide 130 is connected to the rear air guide 120. The front air guide 110, the rear air guide 120, and the two side air guides 130 form a smoke chamber 101; the oil receiving component 200 is connected to the side air guides 130.

[0091] The front air guide 110 is connected to the front panel 150, the rear air guide 120 is connected to the rear back panel 160, and two side air guides 130 are located between the front air guide 110 and the rear air guide 120. The front air guide 110, the rear air guide 120, and the two side air guides 130 form a smoke chamber 101 within the accommodating area. The top of the smoke chamber 101 has an upward-facing opening for communication with the main housing 900, and the bottom of the smoke chamber 101 has a downward-facing smoke inlet 141.

[0092] The front air guide 110, the rear air guide 120 and the two side air guides 130 divide the accommodating area into a smoke chamber 101 and two mounting chambers 102. The two mounting chambers 102 are distributed on both sides of the smoke chamber 101 in the left and right directions and are used to install the electrical components inside the range hood.

[0093] The smoke chamber 101, enclosed by the front air guide 110, the rear air guide 120, and the two side air guides 130, ensures that the fumes will not easily escape after entering and will smoothly enter the main chamber 900, thus concentrating the flow path of the fumes and improving the efficiency and effectiveness of fume extraction.

[0094] By connecting the oil receiving component 200 to the side air guide component 130, the structural strength of the side air guide component 130 can be used to provide stable support for the oil receiving component 200, ensuring that the oil receiving component 200 can effectively collect oil droplets in the appropriate position.

[0095] Combination Figure 5 and Figure 7 As shown, in some embodiments, the oil receiving component 200 is connected to the side air guide component 130 via a connector 300; the connector 300 includes a first connecting portion 310 and a second connecting portion 320 connected to each other, and an included angle is provided between the plane where the first connecting portion 310 is located and the plane where the second connecting portion 320 is located; the first connecting portion 310 is connected to the side air guide component 130, and the second connecting portion 320 is attached to and connected to the oil receiving component 200.

[0096] The connector 300 consists of two parts: a first connecting part 310 and a second connecting part 320. The first connecting part 310 is used to fix the oil receiving part 200 to the side air guide 130 through a connecting structure such as screws or clips, providing a longitudinal installation position for the oil receiving part 200 and avoiding interference between the oil receiving part 200 and the side air guide 130. The second connecting part 320 is attached to the oil receiving part 200 and connected by screws or adhesive, which can maintain good contact and fixation with the oil receiving part 200.

[0097] For example, the connector 300 can be a one-piece structure, which has high strength and is easy to process. Alternatively, the connector 300 can be a split structure, with the first connecting part 310 and the second connecting part 320 connected together by screws, clips, or other structures. In the split-structure connector 300, when the first connecting part 310 and the second connecting part 320 are connected, the relative positions of the first connecting part 310 and the second connecting part 320 can be adjusted by adjusting the position of the connection point, thereby adjusting the installation position of the oil receiving part 200.

[0098] Combination Figure 5 and Figure 6 As shown, in some embodiments, the end of the second connecting portion 320 near the rear air guide 120 is lower than the end of the second connecting portion 320 away from the rear air guide 120; the side of the second connecting portion 320 near the corresponding side air guide 130 is lower than the side of the second connecting portion 320 away from the corresponding side air guide 130.

[0099] The end of the second connecting part 320 near the rear air guide 120 is lower than the end far from the rear air guide 120, so the second connecting part 320 has a certain tilt angle in the front-back direction. Since the second connecting part 320 is in close contact with the oil receiving part 200, the oil receiving part 200 also has a certain tilt angle in the front-back direction, and the oil droplets will naturally flow towards the end of the oil receiving part 200 near the rear air guide 120 under the action of gravity.

[0100] The side of the second connecting part 320 closest to the side guide 130 is lower than the side furthest from the side guide 130, thus the second connecting part 320 has a certain tilt angle in the left-right direction. Since the second connecting part 320 is in close contact with the oil receiving part 200, the oil receiving part 200 also has a certain tilt angle in the left-right direction, and the oil droplets will naturally flow to the lower side under the action of gravity.

[0101] By setting a double tilt angle in the second connecting part 320, the lowest point of the second connecting part 320 can be located in a corner, thereby ensuring that the lowest point of the oil receiving part 200 is also located in a corner. The first channel 220 is located at the lowest position of the oil receiving part 200. On the one hand, this is away from the location of the smoke inlet 141, preventing oil droplets from re-entering the smoke inlet 141 when discharging. On the other hand, it ensures that the oil droplets can flow smoothly to this position for discharge, reducing the residence time of the oil droplets on the oil receiving part 200.

[0102] Combination Figure 5 and Figure 7 As shown, in some embodiments, the oil receiving component 200 is provided with a plug-in portion 240, and the side air guide component 130 is provided with a slot 1331, with the plug-in portion 240 inserted into the slot 1331.

[0103] Specifically, the side air guide 130 includes a first part 131, a second part 132 and a third part 133 connected in sequence. The plane where the first part 131 is located and the plane where the second part 132 is located have an angle; the plane where the second part 132 is located and the plane where the third part 133 is located have an angle.

[0104] The first part 131 has a first flange at its top, and the first part 131 can be connected to the bottom of the main box 900 through the first flange; the second part 132 has a second flange at both ends along the front-to-back direction, and the second part 132 can be connected to the front air guide 110 and the rear air guide 120 through the second flange; the third part 133 has a third flange at both ends along the front-to-back direction, and the third part 133 can be connected to the front air guide 110 and the rear air guide 120 through the third flange; the bottom of the third part 133 also has a fourth flange; the housing 100 includes a bottom plate 140; the third part 133 can also be connected to the bottom plate 140 through the fourth flange; the bottom plate 140 can form the bottom of the smoke chamber 101.

[0105] Specifically, the slot 1331 is provided on the third part 133 of the side air guide 130. By providing the slot 1331, it cooperates with the insertion part 240 of the oil receiving part 200 to ensure that the side of the oil receiving part 200 near the side air guide 130 can be firmly fixed in the predetermined position, preventing displacement or loosening during use.

[0106] Understandably, the engagement of the plug 240 and the slot 1331 forms a stable mechanical connection. This connection method allows the side of the oil receiving part 200 near the side air guide 130 to effectively resist external disturbances (such as fan vibration and airflow changes), thereby ensuring that the side of the oil receiving part 200 near the side air guide 130 is always in a lower position, facilitating the use of gravity to allow oil droplets to flow naturally to the first channel 220, ensuring effective oil droplet discharge.

[0107] For example, the side air guide 130 can be press-formed to form a protrusion that protrudes into the smoke chamber 101, and an inlet / outlet for the insertion part 240 to enter and exit is provided at the bottom or one side of the protrusion; the insertion part 240 can be a protrusion that protrudes from the top of the first oil baffle 210. When the oil receiving part 200 is connected to the side air guide 130 through the connector 300, the protrusion can be inserted into the protrusion through the inlet / outlet.

[0108] Combination Figure 5 and Figure 6 As shown, in some embodiments, the housing 100 includes a base plate 140, the side of the base plate 140 near the front air guide 110 being higher than the side of the base plate 140 near the rear air guide 120; the base plate 140 is provided with a second channel 142, the second channel 142 being used to discharge oil on the base plate 140 into the smoke chamber 101.

[0109] By setting the tilt angle of the base plate 140, the oil droplets will naturally flow to the lower end (the side closer to the rear air guide 120) under the action of gravity. This helps the oil droplets to concentrate and flow to the second channel 142, so that the oil droplets can be smoothly discharged from the base plate 140 and prevent the oil droplets from accumulating on the base plate 140.

[0110] It should be noted that the rear air guide 120 and the rear back plate 160 can be configured to form an auxiliary smoke inlet channel. An oil cup is provided at the bottom of the auxiliary smoke inlet channel. The oil on the bottom plate 140 can enter the auxiliary smoke inlet channel after being discharged through the second channel 142 and fall into the oil cup below.

[0111] For example, a fifth flange may be provided on the side of the base plate 140 near the rear air guide 120, and the base plate 140 may be connected to the rear air guide 120 through the fifth flange. The second channel 142 may be a plurality of through holes provided on the base plate 140, and the second channel 142 is provided near the fifth flange.

[0112] In some embodiments, the smoke inlet 141 is disposed on the base plate 140, and the number of smoke inlets 141 may be greater than or equal to two. The design of multiple smoke inlets 141 can expand the coverage of oil fume extraction, simultaneously handle oil fumes from different directions, reduce the residence time of oil fumes in the air, and improve the capture efficiency of oil fumes.

[0113] Each smoke inlet 141 can be equipped with an independent oil collection device 200 to ensure that oil droplets are effectively collected during the dripping process and to prevent oil droplets from dripping onto the cooking countertop through the smoke inlet 141.

[0114] A second oil-blocking edge 1411 extending upward is provided around the smoke inlet 141. By providing the oil-blocking edge around the smoke inlet 141, a physical barrier can be formed to prevent oil droplets from entering the smoke inlet 141 when they flow on the bottom plate 140.

[0115] In summary, the smoke collection device and range hood provided in this application embodiment, by providing an oil receiving component 200 inside the smoke chamber 101, can effectively collect oil droplets dripping from inside the smoke chamber 101 to the smoke inlet 141, preventing oil droplets from dripping onto the cooking countertop through the smoke inlet 141. Furthermore, the oil receiving component 200 is provided with a first channel 220, which can guide the collected oil droplets onto the base plate 140, preventing excessive accumulation of oil droplets on the oil receiving component 200 and ensuring its continued effectiveness. The base plate 140 is provided with a second channel 142, which discharges oil droplets from the surface of the base plate 140 into the oil cup, ensuring that oil droplets do not accumulate on the base plate 140, maintaining the cleanliness of the base plate 140 and the normal operation of the range hood.
