The circuit board of the oil fume extractor is located in the partition chamber, the operation panel is arranged on the side of the partition plate away from the partition chamber and outside the smoke collecting hood, and is electrically connected with the circuit board. In this way, the partition plate can isolate the oil fume entering the flue from the first smoke inlet from the circuit board, avoids the oil fume from adhering to the circuit board to cause the damage or abnormal work of the device on the circuit board, and prolongs the service life of the circuit board.

Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a range hood. Background Technology

[0002] Currently, during the cooking process in the kitchen, range hoods can quickly expel cooking fumes or odors to the outside through airflow, thereby purifying the kitchen environment, improving the user's cooking experience, maintaining the user's health, and keeping the kitchen clean and hygienic.

[0003] However, the large size of range hoods takes up a lot of space, making them inconvenient to package, transport, and install. For example, to improve the aesthetics of the decor and make efficient use of kitchen space, most range hoods need to be embedded in cabinets, but large range hoods are difficult to integrate with cabinets. Furthermore, due to their size, cookware needs to be kept at a suitable distance from the range hood during use; otherwise, the cookware may interfere with the range hood, affecting operation. Additionally, the lighting components and control panel of the range hood are easily affected by cooking fumes, leading to malfunctions and potential damage. Utility Model Content

[0004] The range hood provided in this application can achieve a thinner design, extending the service life of the control panel.

[0005] The first aspect of this application provides a range hood, comprising:

[0006] The housing has a receiving cavity:

[0007] A fan is installed in the housing and located within the receiving cavity;

[0008] A smoke collection hood is disposed below the housing in the height direction of the housing, and the smoke collection hood includes:

[0009] Cover;

[0010] Front panel, the front panel being connected to the cover;

[0011] The top plate is connected to the upper side of the cover in the height direction of the box body, and the top plate is located above the front panel. The top plate is connected to the box body, and the top plate has a through hole.

[0012] A smoke-collecting plate is connected to the cover and is located between the front panel and the top panel along the height direction of the box. The cover, the front panel, the top panel and the smoke-collecting plate form a smoke duct. The smoke duct is connected to the receiving cavity through the through hole. The smoke-collecting plate is provided with a first smoke inlet that communicates with the smoke duct.

[0013] A baffle plate, wherein the baffle plate is disposed in the flue, the baffle plate comprising:

[0014] A first plate extends along the height direction of the housing and is connected to the smoke collection plate. The first plate and the smoke collection plate partially overlap at the connection point along the height direction of the housing.

[0015] The bent plate section is connected to the first plate section on one side in the depth direction of the box body, and the top plate is connected to the bent plate section;

[0016] The second plate portion is connected to the bent plate portion on the other side of the box body in the depth direction. The second plate portion is connected to the smoke gathering plate. The isolation plate and the smoke gathering plate form an isolation cavity. The first smoke inlet is located on the side of the second plate portion away from the isolation cavity.

[0017] The range hood also includes:

[0018] Circuit board, the circuit board being located within the isolation cavity;

[0019] An operation panel is located on the side of the first plate facing away from the isolation cavity, and the operation panel is electrically connected to the circuit board.

[0020] The range hood disclosed in this application includes a housing and a smoke collection hood disposed below the housing. An isolation plate is installed within the smoke duct of the smoke collection hood. The isolation plate includes a first plate portion, a bent plate portion, and a second plate portion connected sequentially. The first plate portion extends in the height direction of the housing and connects to the smoke gathering plate of the smoke collection hood. The bent plate portion connects to the first plate portion on one side and to the second plate portion on the other side in the depth direction of the housing. The second plate portion also connects to the smoke gathering plate, such that the isolation plate and the smoke gathering plate form an isolation cavity, and the first smoke inlet on the smoke gathering plate is located on the side of the second plate portion opposite to the isolation cavity. The circuit board of the range hood is located in the isolation cavity, and the control panel is disposed on the side of the first plate portion opposite to the isolation cavity and is electrically connected to the circuit board. In this way, the isolation plate can separate the fumes entering the smoke duct from the first smoke inlet from the circuit board, preventing fumes from adhering to the circuit board and potentially damaging or malfunctioning the electronic components on the circuit board, thereby extending the service life of the circuit board and consequently extending the service life of the range hood. In addition, since the first plate and the smoke collection plate overlap at least partially in the height direction of the box, that is, the first plate and the smoke collection plate are stacked and fixedly connected, the connection strength between the two can be strengthened, providing better support for the first plate, thereby reducing the size of the first plate in the height direction of the box and realizing the thinning design of the smoke collection hood. On the other hand, it also helps to improve the overall structural strength of the smoke collection hood.

[0021] In one possible implementation, the range hood further includes:

[0022] A lighting assembly is disposed on the side of the smoke collection plate facing the top plate. The lighting assembly is located in the isolation cavity. The isolation plate is used to isolate the lighting assembly from the airflow entering the flue from the first smoke inlet.

[0023] The lighting components are located in an isolation chamber, and the isolation plate isolates them from the airflow entering the flue from the first smoke inlet. This prevents the oil fumes entering the flue from the first smoke inlet from affecting the lighting components, allowing them to illuminate in a clean air environment and extending their lifespan.

[0024] In one possible implementation, a first sub-bending plate extends along the depth direction of the housing, and one side of the first sub-bending plate is connected to the first plate portion.

[0025] The second sub-bending plate extends along the height direction of the box body. One side of the second sub-bending plate is connected to the other side of the first sub-bending plate away from the first plate. The box body and the top plate are connected to the side of the second sub-bending plate away from the first plate. In the depth direction of the box body, the circuit board is disposed between the first plate and the second sub-bending plate.

[0026] The third sub-bending plate, in the height direction of the box body, is located between the top plate and the smoke collection plate, and the third sub-bending plate is connected to the other side of the second sub-bending plate;

[0027] The fourth sub-bending plate extends along the height direction of the housing. One side of the fourth sub-bending plate is connected to the third sub-bending plate on the other side away from the second sub-bending plate. The other side of the fourth sub-bending plate is connected to the second plate. In the height direction of the housing, the lighting component is located between the smoke-collecting plate and the third sub-bending plate.

[0028] With this configuration, the first and second sub-bending plates, together with the first plate, form a space to accommodate the circuit board. The third and fourth sub-bending plates, together with the smoke-collecting plate, form a space to accommodate the lighting components. Furthermore, the second and third sub-bending plates form a stepped structure through bending, which not only provides a connection point for the housing and the top plate, but also supports the housing and improves the overall structural stability of the range hood.

[0029] In one possible implementation, the smoke-collecting plate includes:

[0030] The first bending portion extends along the height direction of the box body and is connected to the first plate portion. In the depth direction of the box body, the first bending portion and the first plate portion are stacked.

[0031] The first main body extends along the width direction of the box and is arranged at an angle with the top plate. The second plate is connected to the side of the first main body facing the box. The isolation plate, the first bent portion and part of the first main body together form the isolation cavity. The first smoke inlet is located in the first main body.

[0032] The second bend extends along the width direction of the box body, and is connected to the side of the first main body away from the first bend, and is connected to the cover body.

[0033] The first bent portion of the smoke-gathering plate and the first plate portion of the partition plate are stacked together. This thickening increases the connection strength at the joint, thereby reducing their dimensions in the height direction of the enclosure and achieving a thinner smoke hood design. The first main body of the smoke-gathering plate is located below the top plate and has a first smoke inlet. When cooking, the cookware generates upward-flowing fumes and steam, which are then quickly collected and discharged.

[0034] In one possible implementation, the cover includes:

[0035] The rear panel extends along the height direction of the housing and is arranged opposite to the front panel, the smoke collection plate, and the partition plate in the depth direction of the housing;

[0036] Two side panels are located on opposite sides of the rear panel in the width direction of the housing. In the depth direction of the housing, the two side panels are connected between the rear panel and the front panel. The two side panels extend along the height direction of the housing and are both connected to the top panel. The front panel, the top panel, the smoke collection plate, the partition plate, the rear panel, and the two side panels together form the flue. The surfaces of the two side panels that are facing away from each other protrude in a direction away from each other.

[0037] The two side panels of the hood protrude in opposite directions, giving the surface of the smoke hood a suitable textured design that enhances its appearance. This also increases the width of the smoke hood, thereby increasing the width-to-thickness ratio and visually improving its thinning effect. For example, when viewed from an isometric perspective, the smoke hood or range hood of this application appears thinner and lighter due to its larger width-to-thickness ratio.

[0038] In one possible implementation, a gap exists between the front panel and the smoke-collecting plate in the thickness direction of the front panel;

[0039] The smoke collection hood includes:

[0040] An oil mesh is located in the flue. One side of the oil mesh along the depth direction of the housing is connected to the rear panel, and the other side of the oil fume along the depth direction of the housing is connected to the smoke collection plate. In the direction from the front panel to the rear panel, the oil mesh extends obliquely along the housing towards the smoke collection hood.

[0041] The front panel and the smoke collection plate have a gap in the thickness direction of the front panel. By setting this gap, when oil fumes condense and form oil droplets on the smoke collection plate, the oil droplets will not flow onto the front panel, thus keeping the front panel clean and tidy. At the same time, by setting an oil mesh, the oil droplets condensing on the smoke collection plate can be guided by the oil mesh to the rear panel, and then flow from the rear panel into the oil cup, completing the oil collection.

[0042] In one possible implementation, the rear panel includes:

[0043] The rear panel body extends along the height direction of the box and is connected between the two side panels. The oil mesh is connected to the rear panel body. The rear panel body and the front panel are arranged opposite to each other in the depth direction of the box. The front panel is inclined relative to the rear panel body.

[0044] The first rear panel bend is connected to the side of the rear panel body away from the top panel in the height direction of the housing. In the direction of the housing body pointing towards the smoke hood, the first rear panel bend extends obliquely along the rear panel body towards the front panel.

[0045] The second rear plate bend is connected to the side of the first rear plate bend away from the main body of the rear plate. The second rear plate bend extends along the depth direction of the box and is provided with an oil drain hole.

[0046] The range hood also includes:

[0047] An oil cup is located below the second rear plate bend in the height direction of the housing. The portion where the first rear plate bend connects to the second rear plate bend is located in the oil cup. In the height direction of the housing, the orthographic projection of the first rear plate bend is outside the orthographic projection range of the oil cup. The oil cup is used to store oil droplets.

[0048] By tilting the front panel, the thickness of the lower end of the smoke hood can be reduced. Furthermore, by bending the first rear panel, the thickness of the lower end of the smoke hood can be further reduced, thus reducing the volume of the smoke hood. This also ensures that most of the first rear panel bend is located in the oil cup, allowing oil droplets to fall into the oil cup and preventing oil leakage.

[0049] In one possible implementation, the side plate includes:

[0050] The first sub-side plate includes:

[0051] A first extension is located between the rear panel and the front panel in the depth direction of the housing. In the direction from which the smoke hood points to the housing, the first extension extends obliquely from the rear panel toward the front panel, and the side of the first extension away from the rear panel is connected to the front panel.

[0052] In the height direction of the housing, the second extension is located between the first extension and the top plate. In the direction of the smoke hood pointing towards the housing, the second extension extends obliquely along the rear panel toward the front panel, and the extension direction of the second extension forms an angle with the extension direction of the first extension.

[0053] The second sub-side panel, in the depth direction of the housing, is connected to the side of the first extension away from the front panel and connected to the rear panel. In the direction from the first extension to the rear panel, the second sub-side panel extends obliquely toward the other side panel.

[0054] The third sub-side panel is connected to the upper side of the first sub-side panel and the second extension in the height direction of the housing. The first sub-side panel and the second sub-side panel are connected to the top plate through the third sub-side panel. In the direction from the smoke hood to the housing, the third sub-side panel extends obliquely from the second extension toward the direction close to the other side panel.

[0055] By bending the side panels to form three sub-side panels, and bringing the portions of the side panels closer to the rear panel together, the structural strength of the two side panels can be increased by bending them, thereby improving the structural strength of the fume hood. Furthermore, since the second and third sub-side panels extend at an angle relative to the first sub-side panel along a direction closer to each other in the width direction of the housing, the distance between the first sub-side panels forming the front end of the fume hood is larger in the width direction, while the distance between the portions of the second and third sub-side panels forming the rear end of the fume hood is smaller. This allows for a reduction in the overall volume of the fume hood while maintaining the width of the front end, ensuring sufficient width for the first and second smoke inlets to maintain high fume extraction efficiency.

[0056] In one possible implementation, the top plate extends along the width direction of the housing, and in the direction from the rear panel to the front panel, the side of the top plate that connects to the two side panels extends obliquely in a direction away from each other, such that the dimension of the end of the top plate that connects to the rear panel in the width direction of the housing is smaller than the dimension of the end of the top plate that connects to the partition plate in the width direction of the housing.

[0057] In the direction from the rear panel to the front panel, the sides where the top panel connects to the two side panels extend in opposite directions. This, combined with the two side panels, creates an overall shape that is wider at the front and narrower at the back. When the range hood needs to be installed in a cabinet, the narrower rear end makes it easier for the operator to place the range hood inside. The wider front end allows the range hood to maintain a wider smoke inlet, enabling it to maintain high smoke extraction efficiency while reducing its overall size.

[0058] In one possible implementation, the top plate includes:

[0059] The left top plate is connected between the box body and one of the side plates in the height direction of the box body, and the left top plate is also connected to one side of the rear panel in the width direction of the box body;

[0060] The right top plate is connected between the box body and another side plate in the height direction of the box body. The right top plate is also connected to the upper end of the rear plate on the other side in the width direction of the box body. The left top plate and the right top plate are arranged at intervals in the width direction of the box body to form the through hole. The smoke hood communicates with the box body through the through hole.

[0061] The smoke collection hood also includes:

[0062] The first guide plate is located between the rear panel and the front panel in the depth direction of the housing. In the direction from the smoke hood to the housing, the first guide plate also extends obliquely along the left top plate toward the right top plate.

[0063] The second guide plate is located between the rear panel and the front panel in the depth direction of the housing. In the direction from the smoke hood to the housing, the second guide plate also extends obliquely along the right top plate toward the left top plate. The first guide plate and the second guide plate are used to guide the airflow from the smoke hood into the housing.

[0064] By installing a first guide plate and a second guide plate inside the smoke collection hood, the airflow inside the smoke collection hood can be guided into the interior of the housing, allowing the airflow to enter the housing quickly and concentratedly, and then be discharged outdoors by the fan. This can improve the smoke extraction efficiency of the range hood, prevent excessive internal pressure in the range hood, and rectify the airflow inside the range hood, reducing airflow turbulence and thus reducing the noise generated by the range hood during operation.

[0065] Compared with the prior art, the beneficial effects of this application are as follows:

[0066] The range hood disclosed in this application includes a housing and a smoke collection hood disposed below the housing. An isolation plate is installed within the smoke duct of the smoke collection hood. The isolation plate includes a first plate portion, a bent plate portion, and a second plate portion connected sequentially. The first plate portion extends in the height direction of the housing and connects to the smoke gathering plate of the smoke collection hood. The bent plate portion connects to the first plate portion on one side and to the second plate portion on the other side in the depth direction of the housing. The second plate portion is also connected to the smoke gathering plate, such that the isolation plate and the smoke gathering plate form an isolation cavity, and the first smoke inlet on the smoke gathering plate is located on the side of the second plate portion opposite to the isolation cavity. The circuit board of the range hood is located in the isolation cavity, and the control panel is disposed on the side of the first plate portion opposite to the isolation cavity and electrically connected to the circuit board. In this way, the isolation plate can separate the fumes entering the smoke duct from the first smoke inlet from the circuit board, preventing fumes from adhering to the circuit board and potentially damaging or malfunctioning the electronic components on the circuit board, thereby extending the service life of the circuit board and consequently extending the service life of the range hood. In addition, since the first plate and the smoke collection plate overlap at least partially in the height direction of the box, that is, the first plate and the smoke collection plate are stacked and fixedly connected, the connection strength between the two can be strengthened, providing better support for the first plate, thereby reducing the size of the first plate in the height direction of the box and realizing the thinning design of the smoke collection hood. On the other hand, it also helps to improve the overall structural strength of the smoke collection hood. Attached Figure Description

[0089] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0090] In this application, the terms "upper," "rear," "inner," "outer," and "middle," etc., indicate orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing the present invention and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0091] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0092] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable link, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection via an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0093] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0094] Currently, to facilitate user operation of range hoods, a control panel is usually installed at the upper front of the smoke collection hood. Users can control the range hood's start / stop, lighting, and smoke extraction power through this panel. However, the control panel is easily affected by grease buildup inside the range hood, leading to malfunctions, damage, or even failure. This increases maintenance frequency and costs, and shortens the range hood's lifespan. Furthermore, the sheet metal component used to mount the control panel is typically a single piece stamped with the smoke collection plate, with some sheet metal removed later. Considering the strength requirements of the smoke collection hood, the height dimension of the sheet metal component is often large, increasing the hood's thickness, resulting in a poor visual appearance and hindering installation. Alternatively, the sheet metal component for mounting the control panel may consist of the top plate of the smoke collection hood and the smoke collection plate that forms the upper smoke inlet. However, the support for the top plate is relatively simple, resulting in low overall strength of the smoke collection hood and making it prone to wobbling or deformation.

[0095] In view of this, embodiments of this application provide a range hood, including a housing and a smoke collection hood disposed below the housing. An isolation plate is disposed within the smoke duct of the smoke collection hood. The isolation plate includes a first plate portion, a bent plate portion, and a second plate portion connected sequentially. The first plate portion extends in the height direction of the housing and connects to the smoke gathering plate of the smoke collection hood. The bent plate portion connects to the first plate portion on one side and to the second plate portion on the other side in the depth direction of the housing. The second plate portion is also connected to the smoke gathering plate, such that the isolation plate and the smoke gathering plate form an isolation cavity, and the first smoke inlet on the smoke gathering plate is located on the side of the second plate portion opposite to the isolation cavity. The circuit board of the range hood is located in the isolation cavity, and the control panel is disposed on the side of the first plate portion opposite to the isolation cavity and electrically connected to the circuit board. In this way, the isolation plate can separate the fumes entering the smoke duct from the first smoke inlet from the circuit board, preventing fumes from adhering to the circuit board and potentially damaging or malfunctioning the electronic components on the circuit board, thereby extending the service life of the circuit board and consequently extending the service life of the range hood. In addition, since the first plate and the smoke collection plate overlap at least partially in the height direction of the box, that is, the first plate and the smoke collection plate are stacked and fixedly connected, the connection strength between the two can be strengthened, providing better support for the first plate, thereby reducing the size of the first plate in the height direction of the box and realizing the thinning design of the smoke collection hood. On the other hand, it also helps to improve the overall structural strength of the smoke collection hood.

[0096] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0097] Please see Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the smoke collection plate in the embodiments of this application. Figure 2 This is a schematic diagram of the top plate structure in an embodiment of this application. Figure 3 yes Figure 1 The diagram shown is a front view of a range hood. Figure 4 yes Figure 3 The diagram shows a cross-sectional view of the range hood along the A-A' direction.

[0098] In some embodiments, the range hood 1 includes a housing 11, which can serve as a fan frame and has a receiving cavity 11a. It can typically be fixed to a wall so that the range hood 1 is integrally mounted on the wall.

[0099] Understandably, the housing 11 is typically a sheet metal structure with high mechanical strength, enabling the range hood 1 to be securely fixed and supporting other parts of the range hood 1. The housing 11 has two mutually perpendicular width directions (X), depth directions (Y), and height directions (Z).

[0100] In some embodiments, the range hood also includes a fan 12, which is disposed on the housing 11 and located in the receiving cavity 11a. The fan 12 is used to provide power to the range hood 1 to extract cooking fumes.

[0101] In some embodiments, the range hood 1 also includes a smoke collection hood 13, which is disposed below the housing 11 in the height direction Z. During the operation of the range hood 1, the smoke collection hood 13 can collect oil fumes and discharge them through a preset path.

[0102] In some embodiments, the smoke hood 13 includes a hood body 131, which is typically made of sheet metal and has suitable mechanical strength, making it easy to construct the hood into a suitable shape by means of bending, stamping, etc.

[0103] In some embodiments, the smoke hood 13 further includes a front panel 132, which is connected to the hood body 131. The front panel 132 can have a double-layer structure, including a sheet metal layer and a non-metallic layer. The sheet metal layer is directly connected to the hood body 131, and the non-metallic layer covers the side of the sheet metal layer facing away from the hood body 131. The non-metallic layer can be glass, quartz, or rigid plastic, preferably a glass layer, which has a relatively low manufacturing cost, is easy to clean, and is more aesthetically pleasing.

[0104] In some embodiments, the fume hood 13 further includes a top plate 133. In the height direction Z of the housing 11, the top plate 133 is connected to the upper side of the hood 131 and is located above the front panel 132. The top plate 133 is connected to the housing 11. The top plate 133 has a through hole 133a, through which the internal space of the fume hood 13 communicates with the internal space of the housing 11, allowing the oil fumes collected by the fume hood 13 to be discharged outdoors through the fan 12 inside the housing 11. It is understood that the top plate 133 is also a sheet metal part.

[0105] In some embodiments, the smoke hood 13 further includes a smoke gathering plate 134, which is connected to the hood body 131 and located between the front panel 132 and the top plate 133 along the height direction Z of the housing 11. The hood body 131, front panel 132, top plate 133, and smoke gathering plate 134 together form a flue 13a, which communicates with the receiving cavity 11a through the aforementioned through hole 133a. The smoke gathering plate 134 is provided with a first smoke inlet 134a communicating with the flue 13a.

[0106] In some embodiments, the front panel 132 and the smoke collection plate 134 are arranged at an angle, so that the cross-sectional shape of the smoke collection hood 13 perpendicular to the width direction X of the box body 11 is approximately inverted "L" shape. In this way, on the lower side of the smoke collection hood 13, the smoke collection hood 13 can maintain a large distance from the pot, avoiding interference between the smoke collection hood 13 and the pot.

[0107] In some embodiments, the front panel 132 is provided with a second smoke inlet 132a on the side away from the smoke collection plate 134. The second smoke inlet 132a can draw oil fumes from one side of the pot on the stove, so that the range hood 1 has the function of top and side suction, and improves the oil fume extraction effect.

[0108] In some embodiments, the smoke hood 13 further includes an isolation plate 135 located within the flue 13a. The isolation plate 135, together with the smoke gathering plate 134, forms an isolation cavity 135a inside the smoke hood 13, with the first smoke inlet 134a located on the side of the isolation plate 135 facing away from the isolation cavity 135a. Thus, the fumes entering the flue 13a from the first smoke inlet 134a are blocked by the isolation plate 135 and cannot enter the isolation cavity 135a.

[0109] In some embodiments, the range hood 1 further includes a circuit board (not shown) disposed in the isolation chamber 135a, and an operation panel 14 disposed on the side of the first plate portion 1351 opposite to the isolation chamber 135a and electrically connected to the circuit board. In this way, the isolation plate 135 can isolate the fumes entering the flue 13a from the circuit board, preventing the fumes from affecting the circuit board and the operation panel 14. This allows the circuit board and the operation panel 14 to operate in a cleaner air environment, extending their service life and thus extending the service life of the range hood 1.

[0110] In some embodiments, the range hood 1 further includes a lighting component 15 disposed on the smoke collection plate 134. The lighting component 15 is disposed on the side of the smoke collection plate 134 facing the top plate 133 and is located in the isolation cavity 135a. The isolation plate 135 can isolate the lighting component 15 from the airflow entering the flue 13a from the first smoke inlet 134a. In this way, the fumes entering the flue 13a from the first smoke inlet 134a will not affect the lighting component 15, and the lighting component 15 can provide illumination in a clean air environment, which can extend the service life of the lighting component 15.

[0111] Please see also Figures 5 to 7 , Figure 5 yes Figure 4 Enlarged diagram of region B in the middle. Figure 6 This is a schematic diagram of the assembly of the smoke collection plate and the isolation plate in an embodiment of this application. Figure 7 yes Figure 6 The diagram shows a side view of the assembly structure.

[0112] Specifically, the isolation plate 135 includes a first plate portion 1351, a bent plate portion 1352, and a second plate portion 1353. The first plate portion 1351 extends in the height direction Z of the housing 11 and is connected to the smoke-collecting plate 134, with the first plate portion 1351 and the smoke-collecting plate 134 at least partially overlapping in the height direction Z of the housing 11. The bent plate portion 1352 is connected to the first plate portion 1351 on one side in the depth direction Y of the housing 11, and to the second plate portion 1353 on the other side. Furthermore, the top plate 133 is also connected to the bent plate portion 1352, which provides support for the top plate 133. The second plate portion 1353 is connected to the smoke-collecting plate 134, and the first smoke inlet 134a is located on the side of the second plate portion 1353 opposite to the isolation cavity 135a. With this configuration, the first plate 1351 and the smoke collection plate 134 are stacked and fixedly connected, which strengthens the connection between the two and provides better support for the first plate 1351. This reduces the size of the first plate 1351 in the height direction Z of the housing 11, realizes the thinning design of the smoke collection hood 13, and also helps to improve the overall structural strength of the smoke collection hood 13.

[0113] For example, in the depth direction Y of the housing 11, the bent plate portion 1352 can be bent multiple times to form a stepped structure, and the height of the stepped structure gradually increases from bottom to top in the height direction Z of the housing 11. It is understandable that since the smoke collection plate 134 is inclined relative to the top plate 133, and the operation panel 14 needs to be easy for the user to operate, while the lighting component 15 is mainly used to illuminate the stove, the operation panel 14 is located on the first plate portion 1351. In use, the operation panel 14 faces the user directly, and the lighting component 15 is oriented downwards along the height direction Z of the housing 11. In the height direction Z of the housing 11, the height of the lighting component 15 may be less than the height of the operation panel 14. Therefore, bending the bent plate portion 1352 to form a stepped structure can accommodate the distribution design of the operation panel 14 and the lighting component 15, effectively protecting the operation panel 14 and the lighting component 15, while appropriately reducing the size of the isolation cavity 135a, increasing the compactness of the internal structure of the smoke collection hood 13, and helping to reduce the overall volume of the smoke collection hood 13.

[0114] In some embodiments, the bending plate portion 1352 includes a first sub-bending plate 13521, a second sub-bending plate 13522, a third sub-bending plate 13523, and a fourth sub-bending plate 13524. The first sub-bending plate 13521 extends along the depth direction Y of the housing 11. One side of the first sub-bending plate 13521 is connected to the first plate portion 1351, and the other side is connected to one side of the second sub-bending plate 13522. The second sub-bending plate 13522 extends along the height direction Z of the housing 11. The housing 11 and the top plate 133 are connected to the side of the second sub-bending plate 13522 opposite to the first plate portion 1351. It is understood that the circuit board is disposed between the first plate portion 1351 and the second sub-bending plate 13522. Along the height Z of the housing 11, the third sub-bent plate 13523 is located between the top plate 133 and the smoke collection plate 134, and the third sub-bent plate 13523 connects to the other side of the second sub-bent plate 13522. It is understood that, along the height Z of the housing 11, the lighting assembly 15 is located between the smoke collection plate 134 and the third sub-bent plate 13523. The fourth sub-bent plate 13524 extends along the height Z of the housing 11, one side of the fourth sub-bent plate 13524 connects to the other side of the third sub-bent plate 13523 away from the second sub-bent plate 13522, and the other side of the fourth sub-bent plate 13524 connects to the second plate portion 1353. With this configuration, the first sub-bending plate 13521 and the second sub-bending plate 13522, together with the first plate 1351, can form a space to accommodate the circuit board. The third sub-bending plate 13523 and the fourth sub-bending plate 13524, together with the smoke collection plate 134, can form a space to accommodate the lighting component 15. Furthermore, the second sub-bending plate 13522 and the third sub-bending plate 13523 form a stepped structure by bending, which can provide a connection position for the housing 11 and the top plate 133, and can also support the housing 11, thereby improving the overall structural stability of the range hood 1.

[0115] See you again Figures 5 to 7 In some embodiments, the smoke collection plate 134 includes a first bent portion 1341, which extends along the height direction Z of the housing 11 and is stacked and connected to the first plate portion 1351 in the depth direction Y of the housing 11. By stacking and connecting the first bent portion 1341 and the first plate portion 1351, the connection strength between the smoke collection plate 134 and the isolation plate 135 can be improved. The stacked arrangement of the first bent portion 1341 of the smoke collection plate 134 and the first plate portion 1351 of the isolation plate 135 can increase the connection strength at the joint position by thickening, thereby reducing the size of the two in the height direction of the housing 11 and realizing the thinning design of the smoke collection hood 13.

[0116] In some embodiments, the smoke-gathering plate 134 further includes a first main body portion 1342, which extends along the width direction X of the housing 11 and is arranged at an angle to the top plate 133. A second plate portion 1353 is connected to the side of the first main body portion 1342 facing the housing 11. The isolation plate 135, the first bending portion 1341, and part of the first main body portion 1342 together form an isolation cavity 135a. It is understood that the first smoke inlet 134a is disposed on the first main body portion 1342. The first main body portion 1342 is below the top plate 133 and is provided with the first smoke inlet 134a. When the cookware generates oil fumes and water vapor that flow upward with the airflow during cooking, the first main body portion 1342 can gather and collect the upward-flowing oil fumes and water vapor, and can quickly discharge the oil fumes and water vapor.

[0117] In some embodiments, the first main body 1342 is provided with a recessed portion 1342a that is recessed toward the top plate 133. The recessed portion 1342a forms a smoke collection chamber, which can improve the smoke collection effect of the smoke collection hood 13 at the first smoke inlet 134a, thereby improving the smoke extraction efficiency of the range hood 1.

[0118] In some embodiments, the smoke collection plate 134 further includes a second bending portion 1343, which extends along the width direction X of the housing 11 and is connected to the cover 131.

[0119] Please see also Figures 8 to 10 , Figure 8 This is a schematic diagram of the structure of the smoke hood in the embodiments of this application. Figure 9 This is a schematic diagram of the assembly of the rear panel and the oil cup in an embodiment of this application. Figure 10 yes Figure 9 The diagram shows a side view of the assembly structure.

[0120] In some embodiments, the cover 131 includes a rear panel 1311 and two side panels, which are arranged at intervals along the width direction X of the housing 11. In this embodiment, the two side panels can be distinguished as a left side panel 1312 and a right side panel 1313.

[0121] The rear panel 1311 extends along the height direction Z of the housing 11. In the depth direction Y of the housing 11, the rear panel 1311 is arranged opposite to the front panel 132, the smoke collection plate 134, and the partition plate 135. The left side panel 1312 extends along the height direction Z of the housing 11. In the width direction X of the housing 11, the left side panel 1312 connects to one side of the front panel 132 and the rear panel 1311. Simultaneously, the left side panel 1312 is also connected to the top panel 133. Similar to the left side panel 1312, the right side panel 1313 extends along the height direction Z of the housing 11. In the width direction X of the housing 11, the right side panel 1313 connects to the other side of the front panel 132 and the rear panel 1311. Furthermore, the right side panel 1313 is connected to the top panel 133. The rear panel 1311, left side panel 1312, right side panel 1313, front panel 132, top panel 133, smoke collection panel 134 and partition plate 135 form the flue 13a.

[0122] It is understandable that the rear panel 1311, the left side panel 1312, and the right side panel 1313 can all be sheet metal parts, which can improve the consistency of the cover 131 and enhance the overall structural strength of the cover 131.

[0123] In some embodiments, the rear panel 1311 includes a rear panel body 13111, a first rear panel bend 13112, and a second rear panel bend 13113. The rear panel body 13111 extends along the height direction Z of the housing 11 and connects between the left side panel 1312 and the right side panel 1313. The rear panel body 13111 and the front panel 132 are arranged opposite to each other in the depth direction Y of the housing 11. In the height direction Z of the housing 11, the first rear panel bend 13112 is connected to the side of the rear panel body 13111 away from the top panel 133. In the direction from the housing 11 toward the smoke hood 13, that is, from top to bottom in the height direction Z of the housing 11, the first rear panel bend 13112 extends obliquely along the rear panel body 13111 toward the front panel 132, such that the dimension of the lower end of the smoke hood 13 in the depth direction Y of the housing 11 is smaller than the dimension of the upper end of the smoke hood 13 in the depth direction Y of the housing 11. In other words, by tilting the front panel 132 to reduce the thickness of the lower end of the smoke hood 13, the thickness of the lower end of the smoke hood 13 can be further reduced by the bending design of the first rear panel bending portion 13112, thus reducing the volume of the smoke hood 13. Most of the first rear panel bending portion 13112 is located in the oil cup 16, so that the oil droplets fall into the oil cup 16 and prevent the oil droplets from leaking out.

[0124] The second rear plate bending portion 13113 is connected to the side of the first rear plate bending portion 13112 away from the rear plate body 13111 and extends along the depth direction Y of the box 11. The second rear plate bending portion 13113 is provided with an oil drain hole 13113a. The range hood 1 also includes an oil cup 16. In the height direction Z of the housing 11, the oil cup 16 is located below the second rear plate bending portion 13113. The part where the second rear plate bending portion 13113 connects with the first rear plate bending portion 13112 is located in the oil cup 16. In the height direction Z of the housing 11, a part of the orthographic projection of the first rear plate bending portion 13112 is located outside the area covered by the orthographic projection of the oil cup 16. That is to say, through the bending design of the first rear plate bending portion 13112 and the second rear plate bending portion 13113, the thickness of the lower end of the smoke collection hood 13 is reduced, so that the oil cup 16 can collect the oil droplets formed by the condensation of oil fumes inside the smoke collection hood 13 in a smaller size, which helps to achieve the miniaturization design of the oil cup 16.

[0125] In some embodiments, the second rear plate bend 13113 is at least partially recessed from top to bottom in the height direction Z of the housing 11, so that the oil droplets can flow downwards better and fall into the oil cup 16.

[0126] In some embodiments, the front panel 132 is inclined relative to the rear panel 1311, such that the lower end of the housing 11 in the height direction Z of the fume hood 13 in the depth direction Y is smaller than the upper end of the housing 11 in the height direction Z in the depth direction Y. This allows for a thinner overall design of the fume hood 13, increasing the horizontal distance between the fume hood 13 and the cookware on the stovetop, reducing the risk of interference between the fume hood 13 and the cookware. Simultaneously, it also reduces the volume of the fume hood 13, improving its design and making it easier to place in cabinets and install.

[0127] Optionally, the included angle between the front panel 132 and the rear panel 1311 is α, satisfying the relationship: 5°≤α≤30°. This acute angle α can be, for example, 5°, 10°, 15°, 20°, 25°, 30°, or other angles within this range. Within this range, it ensures that the upper portion of the front panel 132 can guide some of the oil fumes to the first smoke inlet 134a of the smoke collection plate 134, improving the smoke extraction effect. It also ensures that the lower portion of the front panel 132 has a smaller thickness, increasing the horizontal distance between the front panel 132 and the cookware. Simultaneously, it allows for a smaller size of the flue 13a in the lower half of the front panel 132, helping the fan 12 to generate a higher airflow velocity at this location, thus improving the efficiency of smoke extraction. At the same time, it allows for a larger size of the flue 13a in the upper half of the smoke collection hood 13, facilitating the merging of oil fumes entering from the first smoke inlet 134a and the second smoke inlet 132a at this location. When α < 5°, the height direction Z of the front panel 132 and the housing 11 is nearly parallel. If the lower part of the fume hood 13 is kept relatively thin, the upper part of the fume hood 13 will have too little space, resulting in a narrow flue and hindering the convergence of airflow from the first smoke inlet 134a and the second smoke inlet 132a. Conversely, if sufficient space is reserved in the upper part of the fume hood 13, the lower part of the fume hood 13 will be thicker, making it easy for the front panel 132 to interfere with the cookware. When α > 30°, the upper part of the fume hood 13 will become larger, which is not conducive to the slim design of the range hood 1. Furthermore, the increased volume of the fume hood 13 will result in an excessively large flue 13a. When the flue 13a is too large, it will be difficult for the fan of the range hood 1 to create a sufficiently low negative pressure inside the fume hood 13 to extract the fumes.

[0128] In some embodiments, the smoke hood 13 further includes a guide plate 136, which is located in the flue 13a and is arranged opposite to the second smoke inlet 132a. The guide plate 136 is used to guide the airflow at the second smoke inlet 132a so that the airflow can enter the interior of the housing 11 more quickly along the flue 13a.

[0129] For example, the deflector plate 136 is arranged at an angle relative to the rear panel body 13111. For instance, in the direction from the rear panel body 13111 to the front panel 132, the deflector plate 136 extends at an angle in the direction from the housing 11 to the smoke hood 13. At both ends of the deflector plate 136 in its extension direction, one end is connected to the rear panel body 13111, and the other end is connected to the second rear panel bend 13113.

[0130] In some embodiments, the surfaces of the left side panel 1312 and the right side panel 1313, which are opposite to each other, protrude in a direction away from each other. This arrangement increases the ratio of the size of the smoke hood 13 in the width direction X of the housing 11 to the size of the smoke hood 13 in the thickness direction of the housing 11, thereby visually improving the thinning effect of the smoke hood 13 and making the appearance of the smoke hood 13 more aesthetically pleasing.

[0131] Please see also Figure 11 , Figure 11 yes Figure 8 The diagram shows a side view of the smoke hood.

[0132] In some embodiments, the left side panel 1312 includes a first sub-side panel 13121, a second sub-side panel 13122, and a third sub-side panel 13123. The first sub-side panel 13121 includes a first extension 131211 and a second extension 131212. In the depth direction Y of the housing 11, the first extension 131211 is located between the rear panel 1311 and the front panel 132. In the direction from the smoke hood 13 to the housing 11, the first extension 131211 extends obliquely from the rear panel 1311 toward the front panel 132, and the side of the first extension 131211 facing away from the rear panel 1311 is connected to the front panel 132. In the height direction Z of the housing 11, the second extension 131212 is located between the first extension 131211 and the top plate 133. In the direction from the smoke hood 13 to the housing 11, the second extension 131212 extends obliquely along the rear panel 1311 toward the front panel 132, and the extension direction of the second extension 131212 forms an angle with the extension direction of the first extension 131211.

[0133] For example, the first extension 131211 and the second extension 131212 are connected to each other and form an L-shaped plate.

[0134] Optionally, the extension directions of the first extension 131211 and the second extension 131212 form an angle β, satisfying the relationship: 110°≤β≤130°. For example, β can be 110°, 115°, 120°, 125°, 130°, or any other angle within the range of this inequality. Within this range, it can be ensured that the lower end of the smoke hood 13 and the front end where the operation panel 14 is located have a small thickness, which helps in the thinning design of the smoke hood 13. At the same time, it ensures that the smoke hood 13 has sufficient space at the position where the front panel 132 and the smoke gathering plate 134 are close together, so as to realize the convergence of airflows entering the smoke hood 13 from different smoke inlets. If β<110°, the first extension 131211 and the second extension 131212 are nearly perpendicular, that is, the front panel 132 and the smoke gathering plate 134 are nearly perpendicular, which is not conducive to the thinning design of the lower end of the smoke hood 13 and the front end where the operation panel 14 is located. If β is greater than 130°, the included angle between the first extension 131211 and the second extension 131212 is too large, which makes the included angle between the front panel 132 and the smoke collection plate 134 too large. This may result in the lower end of the smoke collection hood 13 and the front end where the operation panel 14 is located being too small, making it inconvenient to install the oil cup 16 and the operation panel 14.

[0135] In the depth direction Y of the housing 11, the second sub-side panel 13122 is connected to the side of the first extension 131211 opposite to the front panel 132 and is connected to the rear panel 1311. In the direction from the first extension 131211 to the rear panel 1311, the second sub-side panel 13122 extends obliquely toward the right side panel 1313. In the height direction Z of the housing 11, the third sub-side panel 13123 is connected to the upper side of the first sub-side panel 13121 and the second extension 131212. The first sub-side panel 13121 and the second sub-side panel 13122 are connected to the top panel 133 through the third sub-side panel 13123. In the direction from the smoke hood 13 to the housing 11, the third sub-side panel 13123 extends obliquely from the second extension 131212 toward the right side panel 1313. Understandably, the right side panel 1313 has a similar structure to the left side panel 1312, and the left side panel 1312 and the right side panel 1313 are symmetrically arranged in the width direction X of the housing 11. This allows for the structural strength of the left side panel 1312 and the right side panel 1313 to be increased by bending them, thereby improving the structural strength of the fume hood 13. Furthermore, since the portions of the left side panel 1312 and the right side panel 1313 near the rear panel 1311 are close to each other, the overall volume of the fume hood 13 can be reduced while maintaining the width of the front end of the fume hood 13. This ensures that the first smoke inlet 134a and the second smoke inlet 132a have sufficient width, allowing the range hood 1 to maintain a high smoke extraction efficiency.

[0136] For example, the second sub-side plate 13122 can be a triangular plate, and the third sub-side plate 13123 can also be a triangular plate. Furthermore, the first sub-side plate 13121, the second sub-side plate 13122, and the third sub-side plate 13123 are connected in pairs, so that the three sub-side plates are connected at the same point, and the three sub-side plates form a conical structure at and near the point.

[0137] In some embodiments, the left side plate 1312 and the right side plate 1313 are both integrally formed as a single component, that is, the left side plate 1312 and the right side plate 1313 are both formed by bending sheet metal parts. This can further improve the structural strength of the left side plate 1312 and the right side plate 1313.

[0138] Please see also Figure 12 , Figure 12 yes Figure 8 The diagram shows a top view of the smoke hood.

[0139] In some embodiments, the top plate 133 extends along the width direction X of the housing 11. In the direction from the rear panel 1311 to the front panel 132, the side of the top plate 133 connecting to the left side panel 1312 extends obliquely away from the right side panel 1313, and the side of the top plate 133 connecting to the right side panel 1313 extends obliquely away from the left side panel 1312. Thus, the dimension of the end of the top plate 133 connecting to the rear panel 1311 in the width direction X of the housing 11 is smaller than the dimension of the end of the top plate 133 connecting to the partition plate 135 in the width direction X of the housing 11. That is, the distance between the left side panel 1312 and the right side panel 1313 in the width direction X of the housing 11 increases along the direction from the rear panel body 13111 to the front panel 132. This allows for a larger space at the front end of the fume hood 13 to accommodate the first smoke inlet 134a and the second smoke inlet 132a, thereby improving the fume extraction efficiency of the range hood 1. At the same time, it reduces the size of the rear end of the fume hood 13 and makes the overall size of the fume hood 13 smaller, making it easier to place the fume hood 13 into a cabinet.

[0140] In some embodiments, the top plate 133 includes a left top plate 1331 and a right top plate 1332. In the height direction Z of the housing 11, the left top plate 1331 connects the housing 11 and the left side plate 1312, and is also connected to one side of the rear panel 1311 in the width direction X of the housing 11. The right side plate 1332 connects the housing 11 and the right side plate 1313, and is also connected to the other side of the rear panel 1311 in the width direction X of the housing 11. The left top plate 1331 and the right top plate 1332 are spaced apart in the width direction X of the housing 11, thereby forming the aforementioned through hole 133a.

[0141] Understandably, the side connecting the left top plate 1331 and the left side plate 1312 extends obliquely away from the right side plate 1313 in the direction from the rear panel 1311 to the front panel 132. Correspondingly, the side connecting the right top plate 1332 and the right side plate 1313 extends obliquely away from the left side plate 1312 in the direction from the rear panel 1311 to the front panel 132. For example, when viewing the smoke hood 13 from above in the height direction Z of the housing 11, both the left top plate 1331 and the right top plate 1332 are trapezoidal.

[0142] Please see also Figures 13 to 15 , Figure 13 This is an exploded view of the smoke hood in an embodiment of this application. Figure 14 This is a schematic diagram of the assembly of the first and second guide plates with the cover in an embodiment of this application. Figure 15 This is a schematic diagram of the structure of the first guide plate in the embodiment of this application.

[0143] In some embodiments, the fume hood 13 further includes a first guide plate 137 located within the flue 13a. In the depth direction Y of the housing 11, the first guide plate 137 is located between the rear panel 1311 and the front panel 132. In the direction from the fume hood 13 toward the housing 11, that is, in the height direction Z of the housing 11 from bottom to top, the first guide plate 137 also extends obliquely along the left side panel 1312 toward the right side panel 1313. In this way, the first guide plate 137 can guide the airflow within the fume hood 13 into the interior of the housing 11, allowing the airflow to enter the housing 11 quickly and concentratedly, and then be discharged outdoors by the fan 12. This improves the fume extraction efficiency of the range hood 1 and simultaneously rectifyes the airflow inside the range hood 1, reducing turbulence and thus lowering the noise generated by the range hood 1 during operation.

[0144] For example, the first guide plate 137 is connected to the side of the housing 11 near the left side panel 1312 and also to the rear panel 1311. For instance, the first guide plate 137 includes a first guide body 1371, a first connecting plate portion 1372, and a second connecting plate portion 1373. The first guide body 1371 extends obliquely from the left side panel 1312 toward the right side panel 1313 in the direction from the smoke hood 13 toward the housing 11, thereby guiding the airflow. The first connecting plate portion 1372 is angled to the first guide body 1371 and extends along the height direction Z of the housing 11. The first connecting plate portion 1372 is connected to the housing 11 on one side in the height direction Z and to the first guide body 1371 on the other side. The second connecting plate portion 1373 is arranged at an angle to the first guide body 1371 and extends along the height direction Z of the box 11. The second connecting plate portion 1373 is attached to the rear panel 1311 and connected to the rear panel 1311.

[0145] In some embodiments, the first guide plate 137 further includes a first abutting plate portion 1374. In the depth direction Y of the housing 11, the first abutting plate portion 1374 is located between the first guide body 1371 and the smoke collection plate 134. In the height direction Z of the housing 11, one side of the first abutting plate portion 1374 is connected to the first guide body 1371, and the other side abuts against the top plate 133. In this way, increasing the support position for the first guide plate 137 can improve the positional stability of the first guide plate 137.

[0146] In some embodiments, in the direction from the smoke hood 13 to the housing 11, the first abutment plate portion 1374 may also be configured to extend obliquely from the first airflow guide body 1371 toward the baffle plate 135. This configuration allows the first abutment plate portion 1374 to further guide the airflow.

[0147] In some embodiments, the fume hood 13 further includes a second guide plate 138 located within the flue 13a. In the depth direction Y of the housing 11, the second guide plate 138 is located between the rear panel 1311 and the front panel 132. In the direction from the fume hood 13 toward the housing 11, that is, in the height direction Z of the housing 11 from bottom to top, the second guide plate 138 also extends obliquely along the right side panel 1313 toward the left side panel 1312. In this way, the second guide plate 138 can be used to guide the airflow within the fume hood 13 into the interior of the housing 11, allowing the airflow to enter the housing 11 quickly and concentratedly, and then be discharged outdoors by the fan 12. This improves the fume extraction efficiency of the range hood 1 and simultaneously rectifyes the airflow inside the range hood 1, reducing turbulence and thus lowering the noise generated by the range hood 1 during operation.

[0148] In some embodiments, the second guide plate 138 and the first guide plate 137 are arranged symmetrically in the width direction X of the housing 11. That is, the structure of the second guide plate 138 is basically the same as the structure of the first guide plate 137, which will not be described in detail here.

[0149] Please see also Figure 16 and Figure 17 , Figure 16 This is a schematic diagram of the assembly of the oil mesh and the cover in an embodiment of this application. Figure 17 yes Figure 4 A magnified view of region C in the middle.

[0150] In some embodiments, the front panel 132 and the smoke collection plate 134 have a gap 132b in the thickness direction of the front panel 132. By setting the gap 132b, when oil fumes condense on the smoke collection plate 134 to form oil droplets, the oil droplets will not flow onto the front panel 132, thus keeping the front panel 132 clean and tidy.

[0151] In some embodiments, the smoke hood 13 further includes a first oil mesh 17 disposed within the flue 13a. Along the depth direction Y of the housing 11, one side of the first oil mesh 17 is connected to the rear panel 1311, and the other side is connected to the smoke collecting plate 134. Furthermore, in the direction from the front panel 132 to the rear panel 1311, the first oil mesh 17 extends obliquely along the housing 11 towards the smoke hood 13. Thus, oil droplets condensed on the smoke collecting plate 134 can be guided by the first oil mesh 17 to the rear panel 1311, and then flow from the rear panel 1311 into the oil cup 16, completing the oil collection. Specifically, the second bend 1343 is connected to the first oil mesh 17.

[0152] The first oil mesh 17 extends along the width direction X of the housing 11 and is connected to the left side plate 1312 and the right side plate 1313 respectively. The first oil mesh 17 has a plurality of first through holes 17a arranged at intervals along the width direction X of the housing 11. The airflow entering the smoke hood 13 from the second smoke inlet 132a passes through the first through holes 17a of the first oil mesh 17 and then enters the interior of the housing 11 through the through hole 133a.

[0153] In some embodiments, the first guide plate 137 and the second guide plate 138 can also be connected to the sides of the first oil mesh 17 near the left side plate 1312 and the right side plate 1313, respectively. In this way, the first oil mesh 17 can be used to further support the first guide plate 137 and the second guide plate 138, thereby improving the stability of the first guide plate 137 and the second guide plate 138.

[0154] Please see also Figure 18 and Figure 19 , Figure 18 yes Figure 4 Enlarged diagram of region D in the middle. Figure 19 This is a schematic diagram of the internal structure of the smoke collection hood with a second oil mesh in an embodiment of this application.

[0155] In some embodiments, the fume hood 13 further includes a second oil mesh 18 disposed within the flue 13a. In the height direction Z of the housing, the second oil mesh 18 is located below the first oil mesh 17. The second oil mesh 18 is connected to the front panel 132 and extends obliquely towards the rear panel body 13111. In the height direction Z of the housing 11, the orthographic projection of the end of the second oil mesh 18 away from the front panel 132 lies within the orthographic projection range of the oil cup 16. Thus, if oil fumes condense inside the front panel 132 to form oil droplets, the oil droplets on the front panel 132 can flow along the second oil mesh 18 and into the oil cup 16, thereby preventing oil droplets formed on the inner surface of the front panel 132 from dripping onto the stove or cookware at the lower edge of the front panel 132, thus avoiding oil droplet contamination of the stove or cookware.

[0156] Specifically, in the direction from the front panel 132 to the rear panel body 13111, the second oil mesh 18 also extends obliquely along the direction from the housing 11 toward the smoke hood 13. It can be understood that the second oil mesh 18 may have multiple second through holes 18a arranged at intervals along the width direction X of the housing 11. In this way, the airflow entering the flue 13a from the second smoke inlet 132a continues to flow upward through the second through holes 18a, reducing the impact of the second oil mesh 18 on the airflow inside the flue 13a.
