Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a baffle structure for a range hood and a range hood itself. Background Technology

[0002] A range hood, also known as a cooking hood or range extractor, is a kitchen appliance that purifies the kitchen environment. Installed above the stove, it quickly removes waste from combustion and harmful fumes produced during cooking, expelling them outdoors. It also condenses and collects these fumes, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions.

[0003] In related technologies, some range hoods use a combination of a front air curtain outlet and two side baffles to prevent oil fumes from escaping. However, this requires high-quality baffles, resulting in higher costs. Moreover, the baffles are prone to accumulating oil stains and require regular cleaning by the user. In other range hoods, the air curtain device generally only exhausts air to the front of the range hood. This results in a small exhaust area, which has less impact on the escape of oil fumes from the surrounding area and poor performance. Utility Model Content

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, one objective of the present invention is to propose a baffle structure for a range hood, which, on the one hand, can form a physical structure to block oil fumes to a certain extent, and on the other hand, can guide the air at the air curtain outlet to flow along the air guide groove to form a more stable airflow barrier.

[0005] This utility model further proposes a smoke hood.

[0007] Therefore, by setting up this baffle structure, on the one hand, it can form a physical structure to block the oil fumes to a certain extent, and on the other hand, it can guide the air at the air curtain outlet to flow along the air guide groove to form a more stable airflow barrier, thereby improving the practicality of the baffle structure.

[0008] In some examples of this utility model, the baffle includes: an upper baffle portion connected to the baffle frame and extending in the front-rear direction; and a lower baffle portion connected to the rear of the upper baffle portion and extending in the vertical direction, wherein the upper baffle portion and the lower baffle portion form a groove on the side away from the baffle frame.

[0009] In some examples of this utility model, the width of the upper stop increases from front to back, and the bottom edge of the upper stop extends downward at an angle from front to back to form part of the edge of the groove.

[0010] In some examples of this utility model, the width of the lower stop decreases in the direction from top to bottom, and the front edge of the lower stop extends backward at an angle in the direction from top to bottom and forms an angle with the bottom edge of the upper stop to form another part of the edge of the groove.

[0011] In some examples of this utility model, a transition arc is formed between the front edge of the lower stop and the bottom edge of the upper stop.

[0012] In some examples of this utility model, the baffle frame includes: a main board adapted to be connected to the housing, the main board being provided with the air vent; two connecting plates spaced apart in the left-right direction, the two connecting plates being connected to the lower part of the main board and extending downward, the two connecting plates corresponding one-to-one with the two baffles in the left-right direction, the two connecting plates being located inside the two baffles, and the distance between the edges of the connecting plates and the corresponding sides of the main board in the left-right direction being adapted to the thickness of the baffles on the corresponding sides of the connecting plates.

[0013] In some examples of this utility model, the two connecting plates define clearance spaces with the main board in the left-right direction, and the two baffles are respectively located in the clearance spaces at their corresponding connecting plates.

[0014] In some examples of this utility model, the baffle structure further includes: a shielding member, which is connected to the outside of the motherboard and extends downward along the left-right direction. The shielding member, the connecting plate near the shielding member, and the motherboard together define a mounting groove. One of the two baffles located on the outside is disposed in the mounting groove.

[0015] In some examples of this utility model, the baffle frame further includes: a guide section connected between the two connecting plates, the guide section being located at the edge of the air duct; and / or the connecting plate being bonded to the corresponding baffle.

[0020] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0021] The following is for reference. Figures 1-11 The baffle structure 100 of the range hood 200 according to the present utility model embodiment can, on the one hand, form a physical structure blocking effect on the fumes to a certain extent, and on the other hand, guide the air at the air curtain outlet 2011 to flow along the air guide groove 30 to form a more stable airflow barrier.

[0022] Combination Figures 1-11 As shown, the baffle structure 100 of the range hood 200 according to the first aspect embodiment of the present invention includes a baffle frame 10 and two baffles 20. The baffle frame 10 serves as a mounting bracket for the baffles 20, and the baffles 20 effectively block oil fumes using a physical structure, thereby limiting the diffusion range of the rising oil fumes. For example, the baffle structure 100 can be disposed on the left and right sides of the housing 201, or on the front side of the housing 201.

[0023] Specifically, the baffle frame 10 is adapted to be connected to the housing 201 of the range hood 200. The baffle frame 10 is provided with an air guide 11 corresponding to the air curtain outlet 2011 of the housing 201. Two baffles 20 are installed on the baffle frame 10, and the two baffles 20 are spaced apart from the air guide 11. An air guide groove 30 corresponding to the air guide 11 is formed between the two baffles 20.

[0024] Specifically, the baffle frame 10 is used to establish a connection with the housing 201. The air duct 11 on the baffle frame 10 is connected to the air curtain outlet 2011 on the top plate 202. The baffle 20 is then connected to the baffle frame 10, so that the baffle frame 10 can provide a more reliable connection foundation for the baffle 20. The two baffles 20 are spaced apart from the air duct 11, so as to avoid the baffles 20 from blocking the air duct 11, thereby ensuring that the air duct 11 can be smoothly vented.

[0025] Furthermore, the range hood 20 has two baffles 20 on either the left or right side and the front side. For example, baffle structures 100 are provided on the left and right sides of the range hood 200. This can form a physical structure to block the oil fumes on the left and right sides of the range hood 200 to a certain extent. The two baffles 20 are spaced apart from each other in the left and right direction, and the air guide vents 11 on the baffle frame 10 are located between the two baffles 20 in the left and right direction. This can prevent the baffles 20 from interfering with the normal air outlet of the air guide vents 11, and can also facilitate the formation of an air guide groove 30 between the two baffles 20. That is, the air blown out from the air guide vent 11 can continue to flow along the designated extension path of the air guide groove 30, reducing the problem of disordered air diffusion at the output end due to insufficient air force (the baffle 20 assembly can shorten the oil fume diffusion space that needs to be blocked in the vertical direction of the range hood 200), thereby improving the formation effect of the airflow barrier on the left and right sides of the range hood 200, and thus improving the oil fume blocking effect of the air curtain device 60.

[0026] In summary, compared to traditional range hoods that only have a front air curtain outlet, the embodiment in this case can form airflow barriers on the left, right, and front sides of the range hood 200. This prevents fumes from spreading from the left, right, and front sides of the range hood 200, thereby improving the smoke extraction efficiency of the range hood 200. Furthermore, compared to traditional range hoods with a front air curtain outlet and baffles on the left and right sides (where the left and right sides can only be forcibly blocked by physical structures, and the baffles are large, making it easy for grease to adhere to the inner wall of the baffles, increasing the user's cleaning burden), the baffle 20 assembly in the embodiment of this case is equipped with air guides. The baffle 20 component, also known as the baffle 11, can provide a physical structure for forced smoke blocking on the left and right sides of the range hood 200. Combined with the air guide 11 and the air guide 30, it facilitates the formation of airflow barriers on the left and right sides of the range hood 200 by the airflow at the air curtain outlet 2011 along the baffle 20 component. This not only ensures the blocking of oil fumes but also reduces the space occupied by the baffle structure 100, increases the openness between the range hood 200 and the kitchen countertop, and effectively prevents oil fumes from escaping from the left and right sides, thereby effectively improving the economy and practicality of the range hood 200.

[0027] Therefore, by setting up this baffle structure, on the one hand, it can form a physical structure to block the oil fumes to a certain extent, reducing the space occupied by the baffle 20. On the other hand, it can also guide the air at the air curtain outlet 2011 to flow along the air guide duct 30 to form a more stable airflow barrier, thereby improving the economy and practicality of the baffle structure 100.

[0028] According to some optional embodiments of the present invention, combined with Figures 3-5As shown, the baffle 20 includes an upper baffle 21 and a lower baffle 22. The upper baffle 21 is connected to the baffle frame 10 and extends in the front-rear direction. The lower baffle 22 is connected to the rear of the upper baffle 21 and extends in the vertical direction. The upper baffle 21 and the lower baffle 22 form a groove 23 on the side away from the baffle frame 10.

[0029] The baffle structure 100 is located on both sides of the housing 201 in the left-right direction. The upper baffle 21 extends in the front-back direction, so that the size of the baffle 20 in the front-back direction can cover the size of the smoke collection chamber of the range hood 200 in the front-back direction as much as possible. The lower baffle 22 extends in the vertical direction, so that the size of the baffle 20 in the vertical direction can cover the size between the lower side of the top plate 202 of the housing 201 and the kitchen countertop as much as possible. This ensures that the air blown out of the air vent 11 can form an effective airflow barrier on both sides of the range hood 200, avoid the creation of smoke-blocking blind spots in the airflow barrier, and thus improve the smoke blocking effect.

[0030] Furthermore, the lower baffle 22 extends relative to the upper baffle 21, and the upper baffle 21 and the lower baffle 22 form a groove 23 on the side away from the baffle frame 10. In this way, while ensuring effective blocking of oil fume diffusion through the air guide 11 and the air guide groove 30, the space occupied by the baffle 20 on the vertical plane can also be reduced, thereby reducing the material used in manufacturing the baffle 20, reducing manufacturing costs, and also reducing the oil stains attached to the baffle 20, reducing the cleaning burden on users, and thus improving the practicality of the range hood 200.

[0031] Specifically, in combination Figures 3-5 As shown, the width of the upper stop 21 increases from front to back, and the bottom edge of the upper stop 21 extends downward at an angle from front to back to form part of the edge of the groove 23.

[0032] Understandably, the width of the upper baffle 21 increases from front to back, and the bottom edge of the upper baffle 21 extends downwards at an angle from front to back, while the top edge of the upper baffle 21 extends straight from front to back. This makes it easier for the top edge of the upper baffle 21 to fit onto the flat surface of the top plate 202 connected to the housing 201. On the other hand, it also makes it easier for the upper baffle 21 to gradually increase the area of ​​oil fume blocking from front to back, thereby improving the effect of blocking and collecting smoke. Moreover, the rearward widening of the upper baffle 21 can also more smoothly guide the oil fume towards the smoke inlet (the smoke inlet is usually located in the middle and rear part of the top plate 202 or on the front panel at the rear of the range hood 200).

[0033] Furthermore, combined Figures 3-5As shown, the width of the lower stop 22 decreases in the direction from top to bottom, the front edge of the lower stop 22 extends backward at an angle in the direction from top to bottom, and an angle is formed between the lower stop 22 and the bottom edge of the upper stop 21 to form another part of the edge of the groove 23.

[0034] In other words, the width of the lower baffle 22 decreases from top to bottom. This way, the lower part will not obstruct the view of cooking operations due to its excessive width, thus increasing the openness above the kitchen countertop. At the same time, the wider upper baffle can block the oil fumes that spread to both sides during the rising process. The rear of the lower baffle 22 extends straight down, so that the rear of the lower baffle 22 can be adapted to the flat surface of the front panel connected to the housing 201.

[0035] In addition, the downward-decreasing slope of the lower baffle 22 can guide the oil droplets attached to the baffle 20 to naturally flow downward into the oil collection groove on the housing 201 on the side away from the user, thereby improving the oil stain collection efficiency.

[0036] Furthermore, since the bottom edges of the lower baffle 22 and the upper baffle 21 form an angle, compared to the single-piece baffle 20, the space occupied by the baffle 20 in this case is relatively smaller, provided that the vertical space occupied by the overall baffle 20 is fixed. This can reduce the material used in manufacturing the baffle 20 and also reduce the size manufacturing requirements of the baffle 20, thereby improving manufacturability and economy.

[0037] Specifically, in combination Figures 3-5 As shown, the angle formed between the front edge of the lower stop 22 and the bottom edge of the upper stop 21 is an obtuse angle.

[0038] Understandably, this allows for a larger angle to buffer the connection area between the lower baffle 22 and the upper baffle 21, making the connection between the lower baffle 22 and the upper baffle 21 smoother and more open, reducing the feeling of spatial oppression, increasing the user's activity space during cooking and cleaning, and also improving the connection strength between the two.

[0039] In addition, the gently sloping, obtuse-angled connection area allows oil droplets above the baffle 20 to slide more smoothly down the transition slope between the upper baffle 21 and the lower baffle 22, preventing stubborn oil buildup at the connection point and thus improving oil collection efficiency and reducing the burden of cleaning oil stains on the baffle 20.

[0040] Furthermore, combined Figures 3-5 As shown, a transition arc 24 is formed between the front edge of the lower stop 22 and the bottom edge of the upper stop 21.

[0041] The transition arc 24 serves to evenly connect the front edge of the lower baffle 22 with the bottom edge of the upper baffle 21, preventing stress concentration areas from forming at the connection between the front edge of the lower baffle 22 and the bottom edge of the upper baffle 21, thus improving the uniformity of stress on the baffle 20. The transition arc 24 also prevents the formation of eddies at the connection between the front edge of the lower baffle 22 and the bottom edge of the upper baffle 21. In other words, the smooth surface of the arc can guide the eddies to flow more smoothly along the contour of the baffle 20, reducing the probability of local accumulation of eddies and indirectly improving the smoke collection efficiency.

[0042] In addition, the transition arc 24 can eliminate the risk of sharp edges caused by right angles. When users operate cookware, adjust the range hood 200, or clean the baffle 20 during daily cooking, they can avoid being bumped or scratched by sharp right angles when their arms or bodies accidentally come into contact with the connection between the upper baffle 21 and the lower baffle 22. Moreover, the transition arc 24 has no right angle dead corners, and the cloth can be seamlessly covered along the curved surface when wiping. There is no need to repeatedly dig out the residual oil stains in the right angle gaps, which effectively reduces the difficulty of cleaning. At the same time, it can also reduce the odor problem caused by oil stains being hidden in dead corners for a long time, and keep the appearance of the range hood 200 clean.

[0043] According to some optional embodiments of the present invention, combined with Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the baffle frame 10 includes a main board 12 and two connecting plates 13 spaced apart in the left-right direction. The main board 12 is adapted to be connected to the housing 201. The main board 12 is provided with an air vent 11. The two connecting plates 13 are connected to the lower part of the main board 12 and extend downward relative to the main board 12. The two connecting plates 13 correspond one-to-one with the two baffles 20 in the left-right direction. The two connecting plates 13 are located inside the two baffles 20 and are fitted together with the corresponding baffles 20.

[0044] In other words, the main board 12 is in close contact with the lower surface of the top plate 202, which helps to increase the contact area between the baffle frame 10 and the top plate 202, thereby improving the connection reliability between the two; the main board 12 is provided with an air guide 11, which can prevent the main board 12 from blocking the downward airflow of the side air curtain outlet 2013.

[0045] Two connecting plates 13 are connected to the lower center of the main board 12. The connecting plates 13 extend downward relative to the main board 12, which increases the weight and spatial mode of the main board 12, thereby improving the structural strength and bending and torsional stiffness of the main board 12. The two connecting plates 13 correspond one-to-one with the two baffles 20 in the left and right directions. The two connecting plates 13 are located inside the two baffles 20 and are fitted to the corresponding baffles 20. This arrangement allows the connecting plates 13 to limit the baffles 20 in the left and right directions, thereby ensuring the positional stability of the baffles 20. On the other hand, it can also work with the main board 12 to increase the contact area between the baffle and the baffle 20, thereby improving the connection reliability and relative positional stability between the baffle 20 and the baffle 40, and thus ensuring the working stability of the baffle 20 assembly.

[0046] Furthermore, the distance between the corresponding edges of the connecting plate 13 and the main board 12 along the left-right direction is adapted to the thickness of the baffle 20 on the corresponding side of the connecting plate 13. This allows the baffle 20 to be in close contact with the corresponding edge of the main board 12 while remaining flush with it. This ensures that the baffle 20 has the largest possible contact surface with both the main board 12 and the connecting plate 13, while also preventing the baffle 20 from being too thick and protruding outside the edge of the main board 12. This improves the structural reliability and design rationality of the baffle 20 assembly.

[0047] Alternatively, combined Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the two connecting plates 13 define clearance spaces 14 with the main board 12 in the left and right directions, and the two baffles 20 are located in the clearance spaces 14 at their respective connecting plates 13.

[0048] The two connecting plates 13 define clearance spaces 14 between themselves and the main board 12 in the left and right directions. This facilitates the provision of independent and precise installation areas for the two spaced baffles 20 on one side of the range hood 200. The connecting plates 13 also provide lateral support for the baffles 20, reducing the swaying of the baffles 20 during use (such as cleaning, disassembly, and airflow impact) and improving the positional stability of the baffles 20.

[0049] Alternatively, combine Figure 3 and Figure 4 As shown, the baffle structure 100 also includes a shielding member 40. Along the left and right direction, the shielding member 40 is connected to the outside of the main board 12, and the shielding member 40 extends downward relative to the baffle frame 10. The shielding member 40, the connecting plate 13 near the shielding member 40 and the main board 12 together define the mounting groove 41. One of the two baffles 20 located on the outside is disposed in the mounting groove 41.

[0050] The shield 40 is connected to the outside of the main board 12 and extends downward to the main board 12. The shield 40, the connecting plate 13 near the shield 40, and the main board 12 together define the mounting groove 41. The mounting groove 41 can provide an independent assembly space for the baffle 20, avoiding the risk of damage caused by the end of the baffle 20 near the main board 12 being directly exposed to the outside of the range hood 200. It can also shield the appearance of the connection between the baffle 20 and the main board 12, thereby improving the perceived quality of the appearance. Moreover, the mounting groove 41 can limit the baffle 20 in both left and right directions, thereby improving the stability of the baffle 20 after assembly and avoiding the risk of displacement of the baffle 20 due to airflow impact during long-term use.

[0051] Alternatively, in combination Figure 3 , Figure 4 , Figure 6 , Figure 10 and Figure 11 As shown, the baffle 20 also includes a guide section 15, which is connected between the two connecting plates 13 and is located at the edge of the air duct 11.

[0052] The guide section 15 extends vertically and connects to two spaced connecting plates 13, thus connecting the two connecting plates 13 into a whole, improving the structural strength and bending and torsional stiffness of the connecting plates 13, thereby enhancing the structural reliability of the baffle frame 10. Moreover, the guide section 15 is located at the edge of the air vent 11, which allows the guide section 15 to guide the air flowing out of the air vent 11. In other words, the air blown out of the air vent 11 can flow smoothly to the baffle 20 along the airflow channel defined by the guide section 15 and the two connecting plates 13, avoiding unnecessary airflow diffusion and improving the airflow guiding effect. The guide section 15, together with the connecting plates 13, can also reinforce the air vent 11, thereby ensuring the accuracy, smoothness and stability of the air outlet of the air vent 11.

[0053] Alternatively, the connecting plate 13 is bonded to the corresponding baffle 20.

[0054] The connecting plate 13 and the corresponding baffle 20 are connected as a whole by adhesive bonding. This allows the connecting plate 13 and the baffle 20 to form a tight surface contact and fit. Compared with the traditional screw connection method, this can avoid structural damage caused by drilling holes on the surface of the plate. At the same time, through the curing effect of the adhesive, the supporting force of the connecting plate 13 is evenly transferred to the baffle 20 as a whole, effectively dispersing the external force on the baffle 20. Moreover, the adhesive bonding does not require additional mounting holes 251 or metal connectors, thereby simplifying the production assembly process, improving production efficiency, and maintaining the integrity and flatness of the surface of the baffle 20, avoiding screw protrusions that would damage the appearance.

[0055] Combination Figure 1 , Figure 2 and Figure 7 As shown, the range hood 200 according to the second aspect embodiment of the present utility model includes a housing 201, an air curtain device 60, and a baffle structure 100 of the range hood 200 of the above embodiment. The housing 201 is provided with an air curtain outlet 2011, the air curtain device 60 is disposed inside the housing 201 and communicates with the air curtain outlet 2011, and the baffle frame 10 is connected to the housing 201.

[0056] Specifically, the casing 201, as the main load-bearing structural component of the outer contour of the range hood 200, can protect the internal structure and also provide some sound insulation to reduce the noise generated when the range hood 200 is running; the air curtain device 60 is a functional structure that optimizes the smoke collection and exhaust effect by blowing out airflow to form an airflow barrier, preventing the spread of oil fumes and guiding them to be efficiently sucked into the smoke extraction port of the range hood 200, thereby improving the cleanliness of the kitchen environment.

[0057] Furthermore, the air curtain device 60 is installed inside the housing 201, which provides installation space for the air curtain device 60 and also provides structural protection for it. The air curtain device 60 is connected to the air curtain outlet 2011, which allows the air curtain device 60 inside the housing 201 to supply air to the outside of the housing 201 through the air curtain outlet 2011, thereby successfully forming an airflow barrier that blocks oil fumes. The baffle frame 10 is connected to the housing 201, which allows the baffle structure 100 to be connected to the housing 201 as a whole, thus facilitating the baffle structure 100 to perform its smoke-blocking function.

[0058] Among them, combined Figure 1 and Figure 2 As shown, the casing 201 is provided with a top plate 202, and the top plate 202 is provided with an air curtain outlet 2011. The top plate 202 can block the oil fumes generated during cooking from continuing to spread upward. The air curtain outlet 2011 includes a front air curtain outlet 2012. The front air curtain outlet 2012 is provided at the front of the top plate 202. The front air curtain outlet 2012 can extend only in the left and right direction, or it can extend partly in the left and right direction and then the other part extends in the front and back directions. That is, the front air curtain outlet 2012 can at least exhaust air downward along the front edge of the top plate 202. In this way, an airflow barrier can be formed along the air outlet direction of the front air curtain outlet 2012, thereby preventing the oil fumes from spreading from the open part at the front of the top plate 202.

[0059] In addition, combined Figure 1 and Figure 2As shown, the air curtain outlet 2011 also includes a front air curtain outlet 2012, and side air curtain outlets 2013 are provided on the left and right sides of the top plate 202. The side air curtain outlets 2013 extend in the front-back direction, that is, the side air curtain outlets 2013 discharge air downward along the left and right edges of the top plate 202. In this way, two airflow barriers can be formed along the air discharge direction of the side air curtain outlets 2013, thereby preventing the oil fumes from spreading from the open areas on the left and right sides of the top plate 202.

[0060] Alternatively, combined Figure 7 and Figure 8 As shown, the air curtain device 60 includes a fan 61, an air duct component 62, and a control component 63. The air duct component 62 is connected to the front air curtain outlet 2012 and the side air curtain outlet 2013 respectively. The control component 63 is disposed between the fan 61 and the air duct component 62 to selectively control the air duct component 62 to deliver air to the front air curtain outlet 2012 and the side air curtain outlet 2013.

[0061] The control component 63 is directly connected to the output end of the fan 61. This allows the control component 63 to complete the air path distribution and on / off control before the air generated by the fan 61 enters the air duct 62. This avoids the air pressure loss and ineffective flow caused by the air entering the air duct first and then being adjusted. For example, when the area corresponding to the side air curtain outlet 2013 does not need air supply, the control component 63 can directly cut off the air source without letting the air circulate in the air duct before closing the outlet, thereby effectively reducing energy waste and the extra load on the fan 61.

[0062] In addition, the air duct component 62 is connected to the front air curtain outlet 2012 and the side air curtain outlet 2013 respectively. The front air curtain outlet 2012 and the side air curtain outlet 2013 are set independently of each other. This can avoid the airflow delivered to the front air curtain outlet 2012 and the side air curtain outlet 2013 from the air duct component 62 from interfering with each other, thereby ensuring the stability and independence of the air outlet at each air curtain outlet 2011, avoiding the risk of a single air curtain outlet 2011 failure spreading to the other air curtain outlets 2011, and ensuring the air supply reliability of the air curtain device 60.
