Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a smoke collection device and a kitchen appliance. Background Technology

[0002] Common kitchen appliances such as range hoods and integrated cooktops have smoke extraction functions. Their smoke extraction principle is based on aerodynamics. The impeller of the fan rotates to expel the air inside the volute, creating negative pressure. Atmospheric pressure then draws the air in the kitchen space, carrying the fumes, into the air inlet, and then exhausts the fumes outdoors through the duct and exhaust pipe.

[0003] A range hood consists of a casing and a smoke collection hood. Typically, an air inlet is located at the front of the smoke collection hood, and a filter is installed at the inlet. Cooking fumes enter the smoke collection hood through the filter and are then exhausted by a fan inside the casing. The filter filters out grease particles from the fumes. However, existing filters are usually single-layered. When cooking fumes pass through the filter, some airflow has a higher velocity, resulting in uneven airflow distribution and poor smoke extraction. Furthermore, the fumes do not make sufficient contact with the filter, causing some grease particles to remain unfiltered and enter the casing, accumulating and forming oil droplets, further reducing filtration effectiveness.

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

"Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] See Figures 1 to 5 This embodiment provides a kitchen appliance, which can be a range hood, integrated stove, or integrated range hood, or other household appliances with smoke extraction functions. The kitchen appliance includes a housing 100 and a smoke collection device. The smoke collection device includes a smoke collection assembly 10, which has a smoke collection chamber 101 and an air inlet 102 communicating with the smoke collection chamber 101. The smoke collection assembly 10 is connected to the housing 100. A fan 200 is installed inside the housing 100 or the smoke collection assembly 10 for extracting cooking fumes. The fumes enter the smoke collection chamber 101 from the air inlet 102 and are discharged through a smoke guide channel within the housing 100. Exemplarily, the housing 100 is located at the top of the smoke collection assembly 10, and the fan 200 is located inside the housing 100. This embodiment uses a range hood as an example, which can be a side-suction range hood. The range hood also includes an oil cup 300, which is located at the bottom of the smoke collection assembly 10.

[0049] The smoke collection device also includes an oil mesh assembly 20, which is disposed within the smoke collection chamber 101 and located at the air inlet 102. In this embodiment, the oil mesh assembly 20 includes a first oil mesh 21 and a second oil mesh 22. The first oil mesh 21 is provided with a plurality of first oil holes 211; the second oil mesh 22 is provided with a plurality of second oil holes 221. External airflow can enter the smoke collection chamber 101 from the air inlet 102, and at least part of the airflow flows sequentially through the first oil mesh 21 and the second oil mesh 22. Along the airflow direction, the second oil holes 221 and the first oil holes 211 are staggered. The concentrated airflow in the first oil holes 211 impacts the second oil mesh 22, changing the flow direction and distributing the airflow to various areas of the second oil mesh 22. This avoids excessively high airflow velocity and uneven distribution, effectively filtering the airflow and improving the filtration effect. It can also effectively and evenly distribute the negative pressure to the periphery of the air inlet 102, ensuring a better smoke extraction effect.

[0050] The second oil hole 221 is offset from the first oil hole 211, which can be either partially offset or completely offset. Partial offset means that for each second oil hole 221, some of the second oil holes 221 are aligned with the first oil hole 211. Complete offset means that for each second oil hole 221, the second oil hole 221 is not aligned with the first oil hole 211 at all.

[0051] In some embodiments, the first oil mesh 21 and the second oil mesh 22 are arranged with a front-to-back gap. In some embodiments, the first oil mesh 21 and the second oil mesh 22 are arranged with a vertical gap. In some embodiments, both the first oil mesh 21 and the second oil mesh 22 extend obliquely relative to the horizontal plane and are arranged with a gap.

[0052] For example, the second oil mesh 22 is located above the first oil mesh 21, and in a first plane extending horizontally, the projection of the first oil mesh 21 lies within the projection of the second oil mesh 22. By setting a double-layer oil mesh, oil droplets dripping from above the smoke collection chamber 101 fall onto the second oil mesh 22, which blocks the oil droplets, reducing the amount of oil droplets falling onto the first oil mesh 21, and thus reducing the amount of oil droplets dripping from the first oil mesh 21 onto the stove.

[0053] Because the second oil hole 221 is misaligned with the first oil hole 211, even if some oil droplets drip from the second oil hole 221 onto the first oil mesh 21, they will not drip into the first oil hole 211, thus reducing the amount of oil droplets dripping from the first oil mesh 21 onto the stovetop. For example, in the first plane, the projection of the second oil hole 221 does not coincide with the projection of the first oil hole 211, thereby preventing oil droplets from dripping from the second oil hole 221 into the first oil hole 211.

[0054] The size of the air inlet 102 can be set according to actual needs. For example, such as Figure 1As shown, the length A of the air inlet 102 along the left-right direction of the smoke collection assembly 10 is 300mm-890mm. The width B of the air inlet 102 is 10mm-150mm. By setting the elongated air inlet 102, the wind speed at the air inlet 102 can reach 8.0m / s to 25m / s. The high wind speed of the air inlet 102 can significantly increase the air volume and flow rate, enhancing the smoke extraction efficiency. By enhancing airflow dynamics, it accelerates smoke capture and discharge, making smoke extraction more efficient, smoke control more thorough, and the smoke extraction effect significantly optimized. Figure 2 As shown, the distance D between the lower end of the air inlet 102 and the rear wall of the smoke collection chamber 101 is 30mm-450mm.

[0055] The shape and number of air inlets 102 are not limited herein. Exemplarily, the air inlet 102 is elongated and extends along the left-right direction of the smoke collection assembly 10. One or more air inlets 102 may be provided; for example, such as... Figure 6 As shown, two elongated air inlets 102 are spaced apart along the vertical direction of the smoke collection assembly 10. For example, as... Figure 7 As shown, two elongated air inlets 102 are spaced apart along the left and right sides of the smoke collection assembly 10.

[0056] See Figure 3 , Figures 8 to 13 The first oil mesh 21 includes a first connecting portion 212 and a first extension portion 213. The first connecting portion 212 is connected to the upper side of the air inlet 102, and the first oil hole 211 is disposed on the first extension portion 213. The first extension portion 213 extends upward at an angle relative to the air inlet 102. The first connecting portion 212 serves to fix and support the first oil mesh 21. The first extension portion 213 is inclined relative to the air inlet 102, so that a gap is formed between the first extension portion 213 and the air inlet 102. Some of the oil fumes at the air inlet 102 can directly enter the smoke collection chamber 101 through the gap, increasing the air intake area and improving the smoke extraction efficiency.

[0057] The second oil mesh 22 includes a second connecting portion 222 and a second extension portion 223. The second connecting portion 222 is connected to the upper side of the air inlet 102, and the second oil hole 221 is disposed in the second extension portion 223. The second extension portion 223 is spaced 5mm-50mm away from the first extension portion 213. The second connecting portion 222 serves to fix and support the second oil mesh 22. The spaced arrangement between the second extension portion 223 and the first extension portion 213 reduces air intake resistance and facilitates the smooth passage of oil fumes through the second oil mesh 22. Some oil fumes can directly enter the smoke collection chamber 101 through the space between the second extension portion 223 and the first extension portion 213, thereby improving smoke extraction efficiency.

[0058] The first connecting portion 212 and the second connecting portion 222 can be connected to the same position of the smoke collecting assembly 10, or they can be connected to different positions of the smoke collecting assembly 10. For example, the first connecting portion 212 is connected to a first position of the smoke collecting assembly 10, and the second connecting portion 222 is connected to a second position of the smoke collecting assembly 10, with the second position located above the first position.

[0059] In the front-back direction, the end of the first extension 213 furthest from the first connecting portion 212 is located behind the lower end of the air inlet 102 to prevent oil dripping from the edge of the first extension 213 from entering the air inlet 102 and thus preventing oil from dripping onto the stovetop. In the front-back direction, the end of the second extension 223 furthest from the second connecting portion 222 is located behind the end of the first extension 213 furthest from the first connecting portion 212 to prevent oil dripping from the edge of the second extension 223 from falling onto the first extension 213 and thus preventing oil from dripping onto the stovetop.

[0060] The first extension 213 has a first oil-guiding flange 214 at the end away from the first connecting portion 212. The first oil-guiding flange 214 extends downward at an angle to guide the oil to flow downward. The second extension 223 has a second oil-guiding flange 224 at the end away from the second connecting portion 222. The second oil-guiding flange 224 extends downward at an angle to guide the oil to flow downward.

[0061] In some embodiments, the second extension 223 is arranged parallel to the first extension 213. In some embodiments, the second extension 223 is arranged at an angle to the first extension 213. In the drawings, F represents the distance between the second extension 223 and the first extension 213, and the value of F ranges from 5mm to 50mm. In actual assembly, the size of F can be adjusted according to actual needs. The larger F is, the greater the air volume between the first extension 213 and the second extension 223, and the smaller the wind speed reaching the second oil mesh 22 due to the greater distance. The smaller F is, the smaller the air volume between the first extension 213 and the second extension 223, and the greater the wind speed reaching the second oil mesh 22 due to the closer distance. For example, the distance between the second extension 223 and the first extension 213 is 10mm-40mm. For example, the second extension 223 is spaced 5mm, 10mm, 15mm, 20mm, 25mm, 30mm, 35mm, 40mm, 45mm or 50mm apart from the first extension 213.

[0062] The top surface of the first oil filter 21 is provided with a first baffle 215, which extends around the periphery of the first oil hole 211. By providing the first baffle 215, oil is prevented from entering the first oil hole 211, thereby reducing oil dripping from the air inlet 102 onto the stovetop. The top surface of the second oil filter 22 is provided with a second baffle 225, which extends around the periphery of the second oil hole 221. By providing the second baffle 225, oil is prevented from entering the second oil hole 221, thereby reducing oil dripping from the second oil filter 22 onto the first oil filter 21.

[0063] The second oil mesh 22 can be directly connected to the smoke collection assembly 10, or indirectly connected to the smoke collection assembly 10. For example, as shown... Figures 14 to 16 As shown, the oil mesh assembly 20 also includes an oil mesh support 23, on which the second oil mesh 22 is disposed. The oil mesh support 23 is connected to the smoke collection assembly 10, and the oil mesh support 23 has multiple air passages 231. By setting the oil mesh support 23, it is easy to install the second oil mesh 22, ensuring the distance between the second oil mesh 22 and the first oil mesh 21. The air passages 231 on the oil mesh support 23 reduce air intake resistance, and some oil fumes can enter the smoke collection chamber 101 through the air passages 231, which can maximize air performance. In some embodiments, the first oil mesh 21 can also be connected to the smoke collection assembly 10 via the support.

[0064] For example, the oil mesh support 23 includes a first connecting edge 232, a second connecting edge 233, and a plurality of supporting edges 234 disposed between the first connecting edge 232 and the second connecting edge 233. The first connecting edge 232 is connected to the smoke collection assembly 10, the second connecting edge 233 is connected to the second oil mesh 22, and the plurality of supporting edges 234 are spaced apart, with an air passage 231 formed between adjacent supporting edges 234.

[0065] See Figure 3 , Figure 13 , Figure 17 and Figure 18 An oil baffle 116 is provided on the inner wall of the smoke collection chamber 101 above the air inlet 102. The oil baffle 116 is used to block the flow of oil into the air inlet 102 and guide the oil to flow to the left and right sides of the air inlet 102. By setting up the oil baffle 116, the oil on the inner wall of the smoke collection chamber 101 is prevented from flowing into the air inlet 102, and the oil is prevented from dripping onto the stove. By guiding the oil to flow to the left and right sides of the air inlet 102, the oil is directed to the left and right sides, which facilitates the collection of oil.

[0066] The oil baffle 116 can be disposed on the smoke collection assembly 10, or it can be part of the smoke collection assembly 10, or it can be part of the oil mesh assembly 20. For example, the smoke collection assembly 10 includes the oil baffle 116, which protrudes from the inner wall of the smoke collection chamber 101, and the second oil mesh 22 is connected to the oil baffle 116. The oil baffle 116 not only serves to block oil but also provides support for the second oil mesh 22.

[0067] Oil guide grooves 117 are provided on the inner wall of the smoke collection chamber 101 on the left and right sides of the oil baffle 116. The oil guide grooves 117 are used to guide the oil to flow downward along the inner wall of the smoke collection chamber 101. By setting the oil guide grooves 117, the directional flow of oil is realized, which facilitates the collection of oil.

[0068] The smoke collection assembly 10 includes a positioning folded edge 122, which is arranged circumferentially around the air inlet 102 and inclined inwards towards the air inlet 102. The first connecting portion 212 is provided with a bent section 2121, which fits against the edge of the positioning folded edge 122. The bent section 2121 cooperates with the positioning folded edge 122 to position the first oil screen 21 and ensure the integrity of the air inlet 102.

[0069] In some embodiments, the smoke collection assembly 10 includes a smoke collection hood 11, an air inlet 102 disposed on the front side of the smoke collection hood 11, and an oil filter assembly 20 connected to the smoke collection hood 11. See the specific details in this embodiment. Figure 2 , Figure 3 , Figures 8 to 22 The smoke collection assembly 10 includes a smoke collection hood 11 and a front panel 12. The smoke collection hood 11 forms a smoke collection chamber 101, and a first opening 111 communicating with the smoke collection chamber 101 is provided on the smoke collection hood 11. The front panel 12 is detachably mounted on the front side of the smoke collection hood 11, and a second opening 121 is provided on the front panel 12. The second opening 121 communicates with the first opening 111 to form an air inlet 102. A first oil filter 21 is connected to the front panel 12, and a second oil filter 22 is connected to the smoke collection hood 11. By setting the front panel 12, it is convenient to arrange the control panel, and by setting the first oil filter 21 and the second oil filter 22 separately, the stress is balanced, ensuring structural strength.

[0070] Specifically, the positioning fold 122 is part of the front panel 12 and is located at the edge of the second opening 121. The bent section 2121 fits against the rear side and end of the positioning fold 122, which plays a positioning role for the first oil mesh 21 and ensures the integrity of the air inlet 102.

[0071] Specifically, the smoke hood 11 includes a front plate 112, side plates 113, a top plate 114, and a back plate 115. Two side plates 113 are provided and distributed on the left and right sides of the front plate 112. The front plate 112, side plates 113, top plate 114, and back plate 115 form a smoke collection chamber 101. A first opening 111 is provided on the front plate 112. A front panel 12 is located on the front side of the front plate 112, and both the front plate 112 and the side plates 113 are connected to the front panel 12. This ensures that the smoke hood 11 is subjected to balanced forces, guaranteeing the stability of the front panel 12. The front panel 12 and the smoke hood 11 can be connected by a first locking element, which can be a screw.

[0072] In this embodiment, the plate body on the front plate 112 at the upper edge of the first opening 111 is bent inward to form an oil baffle 116, that is, the oil baffle 116 is integrally formed with the front plate 112, which ensures structural strength, facilitates processing and production, and reduces assembly costs. The oil guide groove 117 is provided on the back of the front plate 112.

[0073] The front panel 12 includes a windward plate 123 and a support plate 124 arranged at an angle. The windward plate 123 extends downward at an angle from front to back. A second opening 121 is provided on the windward plate 123. The windward plate 123 is connected to the front panel 112. The support plate 124 is located below the windward plate 123 and is connected to the side panel 113. The structural arrangement of the front panel 12 gives it an inclined section. The second opening 121 is located on the windward plate 123, thus the second opening 121 is inclined relative to the horizontal plane, which facilitates smoke collection. The windward plate 123 is connected to the front panel 112, and the support plate 124 is connected to the side panel 113 to distribute the force, ensuring that the front panel 12 is subjected to balanced force and the connection is stable.

[0074] For example, the support plate 124 extends vertically from top to bottom. In this embodiment, the length of the side plate 113 is greater than the length of the back plate 115 in the vertical direction, so a portion of the side plate 113 is located below the back plate 115, and the side plate 113 located below the back plate 115 can be connected to the front panel 12. The smoke collection assembly 10 also includes a lower unit plate 13, which is connected to the back plate 115 and located below the back plate 115. The side plate 113, the lower unit plate 13, and the front panel 12 form a lower unit cavity 104.

[0075] The front plate 112 includes a first oil guide plate 1121 and a second oil guide plate 1122 arranged at an angle. A windward plate 123 is disposed in front of the first oil guide plate 1121. The second oil guide plate 1122 extends horizontally and has an oil passage 1123, which connects the smoke collection chamber 101 and the lower chamber 104.
