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. Currently, most smoke collection hoods are assembled using welding or multiple screws, making assembly difficult and resulting in high production costs. After prolonged use, the range hood requires cleaning; however, the difficulty in disassembling leads to labor-intensive internal cleaning, negatively impacting the user experience.

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0045] See Figures 1 to 16 This embodiment provides a kitchen appliance, which can be a range hood, integrated stove, integrated range hood, or other household appliance with smoke extraction function. The kitchen appliance includes a housing 100 and a smoke collection device. The smoke collection device includes a smoke collection assembly 10, which includes a smoke collection hood 11 and a front panel 12. The smoke collection hood 11 forms a smoke collection chamber 101 and includes a front plate 112 and side plates 113. Two side plates 113 are provided and distributed on the left and right sides of the front plate 112. The front plate 112 is provided with a first opening 111 that communicates with the smoke collection chamber 101. The front panel 12 is provided on the front side of the front plate 112 and is provided with a second opening 121. The second opening 121 communicates with the first opening 111 to form an air inlet 102. The front panel 12 is snapped onto the side plates 113 and is detachably connected to the front plate 112.

[0046] Both the front panel 112 and the side panel 113 are connected to the front panel 12, ensuring balanced force distribution on the smoke hood 11 and guaranteeing the stability of the front panel 12. The snap-fit ​​connection between the front panel 12 and the side panel 113 reduces the number of parts, increases ease of assembly and disassembly, lowers production costs, facilitates cleaning of the smoke collection assembly 10, and reduces labor intensity. The front panel 12 and the front panel 112 are detachably connected, which can be via snap-fit, magnetic connection, or locking mechanism.

[0047] 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 to extract cooking fumes. The fumes enter the smoke collection chamber 101 from the air inlet 102 and are discharged through the smoke guide channel inside the housing 100. For example, 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.

[0048] The size of the air inlet 102 can be set according to actual needs. For example, such as Figure 1 As 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 air velocity at the air inlet 102 is 8.0m / s to 25m / s. The high air velocity 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 D3 between the lower end of the air inlet 102 and the rear wall of the smoke collection chamber 101 is 30mm-450mm.

[0049] The shape and number of air inlets 102 are not limited here. Exemplarily, the air inlets 102 are elongated and extend along the left-right direction of the smoke collection assembly 10. One or more air inlets 102 may be provided; exemplarily, two elongated air inlets 102 are spaced apart along the vertical direction of the smoke collection assembly 10. Exemplarily, two elongated air inlets 102 are spaced apart along the left-right direction of the smoke collection assembly 10.

[0050] 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 by a first locking member. The support plate 124 is located below the windward plate 123 and is engaged with the side panel 113. The structural arrangement of the front panel 12 results in 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, facilitating 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.

[0051] The support plate 124 has first flanges 1241 on both its left and right sides, and a second flange 1131 on its side plate 113. One of the first flanges 1241 and the second flange 1131 has a buckle 1242, and the other has a first latch 1132. The buckle 1242 is inserted into the first latch 1132 for engagement. By using the buckle 1242, installation is simple: just align the buckle 1242 with the first latch 1132 and insert it to complete the engagement, making assembly and disassembly convenient. The first flanges 1241 and the second flange 1131 increase the structural strength of the buckle 1242 and the first latch 1132, ensuring a stable connection.

[0052] For example, a buckle 1242 is provided on the first flange 1241, and a first slot 1132 is provided on the second flange 1131. The buckle 1242 is inserted into the first slot 1132 and engaged with the second flange 1131.

[0053] For example, the first flange 1241 is disposed on the rear side of the support plate 124 to ensure the flatness and aesthetics of the front side of the support plate 124. The opening of the buckle 1242 faces upward. During installation, the second flange 1131 is located behind the first flange 1241. After the buckle 1242 is inserted into the first slot 1132, the front panel 12 is slid upward so that the buckle 1242 engages with the edge of the first slot 1132, that is, engages with the side plate 113.

[0054] The back of the windshield 123 has a third flange 1231, on which multiple first connecting pieces 1232 are provided. A second latch 1124 is provided on the front plate 112 corresponding to the positions of the first connecting pieces 1232. A second connecting piece 1125 is provided at the second latch 1124. The first connecting pieces 1232 are inserted into the second latch 1124 and connected to the second connecting pieces 1125 via a first locking member. The first connecting pieces 1232 and 1125 facilitate screw installation and ensure structural strength. The third flange 1231 increases the structural strength of the first connecting pieces 1232, ensuring a stable connection.

[0055] The second connecting piece 1125 is disposed on the back of the front panel 112. During installation, the front panel 12 is located on the front side of the front panel 112. The first connecting piece 1232 is inserted into the second bayonet 1124. Therefore, the front panel 12 can cover the second bayonet 1124, ensuring the integrity and aesthetics of the front side of the front panel 12.

[0056] Multiple second connecting pieces 1125 can be arranged circumferentially around the front panel 112. For example, multiple second connecting pieces 1125 are distributed on the top side, left and right sides and the bottom side of the first opening 111 of the front panel 112 to ensure sufficient structural strength.

[0057] The first locking element can be a screw. For example, the first connecting piece 1232 has a first connecting hole, and the second connecting piece 1125 has a second connecting hole. The first connecting piece 1232 is inserted into the second bayonet 1124 so that the first connecting hole and the second connecting hole are aligned, which facilitates the installation of the screw.

[0058] To facilitate the installation of the first locking member, the first connecting piece 1232 is inclined relative to the windward plate 123, and the second connecting piece 1125 is parallel to the first connecting piece 1232. For example, the bottom end of the first connecting piece 1232 is connected to the back of the windward plate 123, and the first connecting piece 1232 is inclined outward relative to the windward plate 123.

[0059] In this embodiment, the length of the side plate 113 is greater than the length of the front plate 112 in the vertical direction. Therefore, part of the side plate 113 is located below the front plate 112, which facilitates connection with the support plate 124. For example, the support plate 124 extends vertically from top to bottom, which facilitates connection with the side plate 113.

[0060] The front panel 112 includes a first oil guide plate 1121 and a second oil guide plate 1122 arranged at an angle. A first opening 111 is provided on the first oil guide plate 1121. The front panel 12 is provided on the front side of the first oil guide plate 1121. The windward plate 123 of the front panel 12 is connected to the first oil guide plate 1121. The second oil guide plate 1122 is provided at the bottom of the first oil guide plate 1121 and has an oil outlet 1123. The oil outlet 1123 is connected to the smoke collection chamber 101.

[0061] For example, the second oil guide plate 1122 extends in the horizontal direction and serves as the bottom wall of the smoke collection chamber 101. By opening the oil passage 1123, the oil flowing down the inner wall of the smoke collection chamber 101 can flow downward through the oil passage 1123.

[0062] The second oil guide plate 1122 is spaced apart from the side plate 113 on its left and right sides. Even if the side plate 113 falls, the second oil guide plate 1122 will not deform, and the spaced arrangement reduces stress concentration, effectively protecting the structural integrity of the component. For example, notches 11221 are provided on the left and right sides of the second oil guide plate 1122 to space it apart from the side plate 113.

[0063] The smoke hood 11 also includes a top plate 114 and a back plate 115. The front end of the side plate 113 is welded to the front plate 112, the top end of the side plate 113 is connected to the top plate 114 by a first fastener, and the rear end of the side plate 113 is connected to the back plate 115 by a second fastener. This design ensures structural strength and facilitates installation and disassembly. The welding arrangement makes the front end of the smoke hood 11 more integral and aesthetically pleasing. The first and second fasteners can be screws.

[0064] The smoke collection assembly 10 also includes a lower plate 13, which is connected to the back plate 115 and located below the back plate 115. The side plate 113, the lower plate 13, and the front panel 12 form a lower chamber 104. The side plate 113 of the smoke hood 11 can be matched with different lower plates 13, expanding the range of applications. The oil cup 300 is located at the bottom of the lower chamber 104. The oil passage 1123 on the second oil guide plate 1122 connects the smoke collection chamber 101 and the lower chamber 104, so that oil can flow into the oil cup 300.

[0065] See Figures 1 to 18 The smoke collection assembly 10 also includes two baffles 14, which are distributed on the left and right sides of the smoke collection hood 11. The front panel 112 and / or the side panel 113 are detachably connected to the baffles 14 via a second locking member. The baffles 14 and the front panel 12 form a smoke collection chamber 103, and the air inlet 102 communicates with the smoke collection chamber 103. By setting the baffles 14 to cooperate with the front panel 12 to form the smoke collection chamber 103, the escape of side fumes is prevented, the smoke collection effect is improved, and the smoke extraction effect is enhanced. The second locking member can be a screw.

[0066] For example, the wind deflector 14 includes a fourth flange 141, on which a first recessed platform 142 is provided. A first recessed groove 1133 is provided at a position corresponding to the first recessed platform 142 on the front plate 112 and / or the side plate 113. The first recessed platform 142 is inserted into the first recessed groove 1133 and locked in place by a second locking member. The cooperation between the first recessed platform 142 and the first recessed groove 1133 positions the wind deflector 14, improving its stability.

[0067] The first recessed platform 142 has a third connecting hole, and the first recessed groove 1133 has a fourth connecting hole. The first recessed platform 142 is inserted into the first recessed groove 1133 so that the third connecting hole and the fourth connecting hole are aligned, which facilitates the installation of screws.

[0068] For example, both the front panel 112 and the side panel 113 are connected to the wind deflector 14. During installation, the second flange 1131 of the side panel 113 is located behind the fourth flange 141, and the front panel 12 is located in front of the fourth flange 141 to ensure the integrity and aesthetics of the front panel 12. The fourth flange 141 avoids the first latch 1132 on the second flange 1131, and at the same time, the fourth flange 141 avoids the second latch 1124 on the front panel 112 to prevent affecting the installation of the front panel 12.

[0069] The shape of the wind deflector 14 is not limited here. The rear end of the wind deflector 14 is adapted to the front plate 112 and the side plate 113, and the front end of the wind deflector 14 extends downward at an angle from front to back. Exemplarily, the distance between the top front end of the wind deflector 14 and the rear wall of the smoke collection chamber 101 is 100mm-500mm, that is, the distance between the top front end of the wind deflector 14 and the back plate 115 of the smoke collection hood 11. Figure 2 The distance between the bottom front end of the wind deflector 14 and the rear wall of the smoke collection chamber 101 is 10mm-500mm, that is, the distance between the bottom front end of the wind deflector 14 and the back plate 115 of the smoke collection hood 11. Figure 2 It is represented by D2.

[0070] See Figures 1 to 20 The smoke collection device also includes an oil mesh assembly 20, which is disposed in the smoke collection chamber 101 and located at the air inlet 102. The oil mesh assembly 20 can be a single-layer oil mesh or a double-layer oil mesh.

[0071] For example, the oil mesh assembly 20 includes a first oil mesh 21 and a second oil mesh 22, with the second oil mesh 22 located above the first oil mesh 21. The first oil mesh 21 has a plurality of first oil holes 211, and the second oil mesh 22 has 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 direction of airflow, 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 good smoke extraction effect.

[0072] 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.

[0073] 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.

[0074] In this embodiment, the second oil mesh 22 is connected to the front panel 112, and the first oil mesh 21 is connected to the front panel 12. By separating the first oil mesh 21 and the second oil mesh 22, the forces are balanced, ensuring structural strength.

[0075] 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.

[0076] 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.
