Description

Technical Field

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

[0002] A range hood, also known as an oil extraction hood or oil fume extractor, is a kitchen appliance used to purify 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 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, less impact on the escape of oil fumes from the surrounding area, and poorer performance. Utility Model Content

[0019] 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.

[0020] The following is for reference. Figures 1-10 According to the present invention, the range hood 100 can guide the air blown out from the side air curtain outlet 111 downward through the baffle assembly 30. This allows the baffle assembly 30 to physically block the oil fumes to a certain extent, and also allows the air to form a more stable airflow barrier on the left and right sides of the range hood 100 along the baffle assembly 30.

[0021] Combination Figures 1-10 As shown, the range hood 100 according to the first aspect of this utility model includes a housing 10, an air curtain device 20, and a baffle assembly 30. The housing 10, as the main load-bearing structural component of the external outline of the range hood 100, protects the internal structures and provides sound insulation, reducing noise generated during operation. The air curtain device 20 is a functional structure that optimizes smoke collection and exhaust by blowing out airflow to form an airflow barrier, preventing the spread of fumes and guiding them to be efficiently drawn into the range hood 100's intake port, thereby improving the cleanliness of the kitchen environment. The baffle assembly 30 physically blocks the spread of fumes from the left and right sides of the housing 10, limiting the range of spread when fumes rise, thus improving the smoke extraction and exhaust effect of the range hood 100.

[0022] Specifically, the housing 10 is provided with a top plate 11, and a side air curtain outlet 111 is provided on the side of the top plate 11 in the left and right direction. An air curtain device 20 is provided inside the housing 10 and supplies air to the side air curtain outlet 111. A baffle assembly 30 is provided on the side of the top plate 11 in the left and right direction.

[0023] Specifically, side air curtain outlets 111 are provided on the left and right sides of the top plate 11. The side air curtain outlets 111 extend in the front-to-back direction, that is, the side air curtain outlets 111 can discharge air downwards along the left and right edges of the top plate 11. This facilitates the formation of two airflow barriers along the air discharge direction of the side air curtain outlets 111, thereby preventing the spread of oil fumes from the open areas on the left and right sides of the top plate 11.

[0024] Furthermore, since the baffle assembly 30 is also located on the left and right sides of the housing 10, as arranged as above, the baffle assembly 30 can, on the one hand, form a physical structure to block the oil fumes on the left and right sides of the range hood 100 to a certain extent, and on the other hand, it can also allow the air blown out from the side air curtain outlet 111 to flow along the extension direction of the baffle assembly 30. The air blown out from the side air curtain outlet 111 can flow along the baffle assembly 30 to form a wall-attaching effect. That is, the baffle assembly 30 can more accurately guide the flow path of the air blown out from the side air curtain outlet 111, reducing the problem of disordered diffusion of the air at the output end due to insufficient wind power (the baffle assembly 30 can shorten the oil fume diffusion space that needs to be blocked in the vertical direction of the range hood 100, and can also help guide the air blown out from the side air curtain outlet 111 to form a more stable airflow barrier), thereby improving the formation effect of the airflow barrier on the left and right sides of the range hood 100, and thus improving the smoke blocking effect of the air curtain device 20.

[0025] Furthermore, 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 and right sides of the range hood 100. This prevents fumes from spreading from the left and right sides of the range hood 100, thereby improving the smoke extraction effect of the range hood 100. Also, 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, the baffles are large, and oil stains easily adhere to the inner walls of the baffles, increasing the user's cleaning burden), the baffle assembly 30 in the embodiment of this case, in conjunction with the side baffles on the left and right sides of the top plate 11... The air curtain outlet 111, also known as the baffle assembly 30, can provide a physical structure for forced smoke blocking on the left and right sides of the range hood 100. Furthermore, the airflow at the side air curtain outlet 111 can form a more stable airflow barrier on the left and right sides of the range hood 100 along the extension direction of the baffle assembly 30. This airflow barrier can reduce the space occupied by the baffle assembly 30, increase the openness between the range hood 100 and the kitchen countertop, and effectively prevent fumes from escaping from the left and right sides, thereby effectively improving the economy and practicality of the range hood 100.

[0026] Therefore, by setting up this range hood 100, the baffle assembly 30 can guide the air blown out from the side air curtain outlet 111 downwards. This allows the baffle assembly 30 to physically block the oil fumes to a certain extent, and also allows the air to form a more stable airflow barrier on the left and right sides of the range hood 100 along the baffle assembly 30, thereby improving the oil fume blocking effect, reducing the space occupied by the baffle 33, and thus improving the user experience.

[0027] According to some optional embodiments of the present invention, combined with Figures 3-5 , Figure 8 and Figure 9 As shown, the baffle assembly 30 includes a baffle frame 32 and a baffle 33. The baffle frame 32 is connected to the bottom of the top plate 11. The baffle frame 32 is provided with an air guide 31, which corresponds to the side air curtain outlet 111. The baffle 33 is provided on the baffle frame 32 and extends in the front-back direction and the up-down direction to guide the air blown out from the side air curtain outlet 111 to flow along the extension direction of the baffle 33.

[0028] It is understandable that the baffle frame 32 is used to establish a connection with the top plate 11, and the baffle 33 is then connected to the baffle frame 32, so that the baffle frame 32 can provide a more reliable connection foundation for the baffle 33.

[0029] In addition, the baffle 33 extends in the front-to-back direction, so that the size of the baffle 33 in the front-to-back direction can cover the size of the top plate 11 in the front-to-back direction as much as possible. The baffle 33 extends in the vertical direction, so that the size of the baffle 33 in the vertical direction can cover the size between the lower side of the top plate 11 and the top of the stove as much as possible. This ensures that the air blown out from the side air curtain outlet 111 can form an effective airflow barrier on the left and right sides of the range hood 100, avoid blind spots in the airflow barrier, and improve the oil fume blocking effect.

[0030] Preferably, the baffle 33 and the air vent 31 are spaced apart, which can avoid the baffle 33 physically blocking the air vent 31, thereby ensuring that the air vent 31 can smoothly discharge air.

[0031] Furthermore, combined Figure 3 , Figure 4 and Figure 8 As shown, there are two baffles 33, which are spaced apart in the left and right direction. The air blown out of the side air curtain outlet 111 blows out between the two baffles 33.

[0032] In other words, the range hood 100 has two baffles 33 on each side, with the two baffles 33 spaced apart in the left and right directions. This allows the two baffles 33 to define the air guide channel, so that the air blown out from the side air curtain outlet 111 can continue to flow along the designated extension path of the air guide channel. This helps to forcibly form an airflow barrier in the designated area, thereby improving the forming effect of the smoke-blocking air curtain and thus better blocking the spread of oil fumes.

[0033] Specifically, in combination Figure 2 and Figure 3 As shown, the portion of the baffle frame 32 located between the two baffles 33 is provided with an air guide 31, which corresponds to and is connected to the side air curtain outlet 111.

[0034] Understandably, the air vent 31 on the baffle frame 32 is positioned between the two baffles 33 in the left-right direction. This avoids the baffles 33 interfering with the normal airflow from the air vent 31 and allows the two baffles 33 to form an air guide channel. This means that the air blown out from the air vent 31 can continue to flow along the designated extension path of the air guide channel, which helps to forcibly form an airflow barrier in a designated area, thereby improving the smoke blocking effect. In addition, since the air vent 31 on the baffle assembly 30 corresponds to the side air curtain outlet 111, this arrangement allows the baffle assembly 30 to form a physical structure blocking effect on the left and right sides of the range hood 100 to a certain extent. On the other hand, it also allows the air blown out from the side air curtain outlet 111 to flow sequentially along the extension direction of the air vent 31 and the baffle assembly 30, which means more accurately guiding the airflow path and reducing the problem of disordered air diffusion at the output end due to insufficient airflow. This improves the formation effect of the airflow barrier on the left and right sides of the range hood 100, thereby improving the smoke blocking effect of the air curtain device 20.

[0035] Specifically, in combination Figure 3 and Figure 4 As shown, the baffle 33 includes an upper baffle 331 and a side baffle 332. The upper baffle 331 is connected to the baffle frame 32, and the width of the upper baffle 331 increases from front to back. The side baffle 332 is connected to the rear of the upper baffle 331, and the width of the side baffle 332 decreases from top to bottom. The upper baffle 331 and the side baffle 332 form a groove 333 on the side away from the baffle frame 32.

[0036] Understandably, the width of the upper baffle 331 increases from front to back, which facilitates the gradual increase of the fume-blocking area of ​​the upper baffle 331 in the direction from front to back, thereby improving the fume-blocking and fume-gathering effect. Moreover, the rearward widening of the upper baffle 331 can also more smoothly guide the fumes towards the smoke inlet (the smoke inlet is usually located in the middle and rear part of the top plate 11 or on the front panel 12 at the rear of the range hood 100). The side baffle 332 is connected to the rear end of the upper baffle 331, and the width of the side baffle 332 decreases from top to bottom. This way, it will not obstruct the cooking operation view due to its excessive width at the bottom, improve the openness above the stove, and can also block the fumes that spread to both sides during the rising process through its wider upper shielding surface.

[0037] Alternatively, the downward-decreasing slope of the side baffle 332 can guide oil droplets adhering to the baffle 33 to naturally flow downward into the oil collection trough on the side away from the user, thereby improving the oil stain collection efficiency.

[0038] In addition, the upper baffle 331 extends relative to the side baffle 332, and the upper baffle 331 and the side baffle 332 form a groove 333 on the side away from the baffle frame 32. In this way, while ensuring effective blocking of the spread of oil fumes on the left and right sides through the air guide 31, the space occupied by the baffle 33 on the vertical plane can also be reduced, thereby reducing the material used in manufacturing the baffle 33, reducing manufacturing costs, and also reducing the oil stains attached to the baffle 33, reducing the cleaning burden on users, and thus improving the practicality of the range hood 100.

[0039] Furthermore, combined Figure 3 , Figure 4 , Figure 9 and Figure 10 As shown, the baffle frame 32 includes a main board 321 and two connecting plates 322 spaced apart in the left and right direction. The main board 321 is connected to the lower side of the top plate 11 and is provided with an air vent 31. The two connecting plates 322 are connected to the lower part of the main board 321 and extend downward relative to the main board 321. The two connecting plates 322 correspond one-to-one with the two baffles 33 in the left and right direction and are located inside the two baffles 33.

[0040] In other words, the main board 321 is closely attached to the lower surface of the top plate 11, which helps to increase the contact area between the baffle frame 32 and the top plate 11, thereby improving the connection reliability between the two; the main board 321 is provided with an air guide 31, which can prevent the main board 321 from blocking the downward airflow of the side air curtain outlet 111.

[0041] Two connecting plates 322 are connected to the lower middle part of the main board 321. The connecting plates 322 extend downward relative to the main board 321, which increases the weight and spatial modes of the main board 321, thereby improving the structural strength and bending and torsional stiffness of the main board 321. The two connecting plates 322 correspond one-to-one with the two baffles 33 in the left and right directions. The two connecting plates 322 are located inside the two baffles 33 and are fitted to the corresponding baffles 33. This arrangement allows the connecting plates 322 to limit the baffles 33 in the left and right directions, thereby ensuring the positional stability of the baffles 33. On the other hand, it can also work with the top plate 11 to increase the connection contact area between the baffle frame 32 and the baffles 33, thereby improving the connection reliability and relative positional stability between the baffles 33 and the shielding member 34, and thus ensuring the working stability of the baffle assembly 30.

[0042] Furthermore, the distance between the edges of the connecting plate 322 and the corresponding side of the main board 321 along the left-right direction is matched with the thickness of the baffle 33 on the corresponding side of the connecting plate 322. This allows the baffle 33 to be in close contact with the corresponding side edge of the main board 321 while remaining flush with it. This ensures that the baffle 33 has the largest possible contact surface with both the main board 321 and the connecting plate 322, while also preventing the baffle 33 from being too thick and protruding outside the edge of the main board 321. This improves the structural reliability and design rationality of the baffle assembly 30.

[0043] Specifically, in combination Figure 3 and Figure 4 As shown, the two connecting plates 322 define a clearance area 323 with the main board 321 in the left and right directions, respectively, and the two baffles 33 are located in the clearance area 323 of their corresponding connecting plates 322.

[0044] Among them, the two connecting plates 322 define the avoidance area 323 with the main board 321 in the left and right directions, which makes it easier to provide an independent and precise installation area for the two spaced baffles 33 on one side of the range hood 100. The connecting plates 322 can also provide lateral support for the baffles 33, reduce the shaking of the baffles 33 during use (such as cleaning and disassembly, airflow impact), and improve the positional stability of the baffles 33.

[0045] Furthermore, combined Figure 3 and Figure 4 As shown, the baffle assembly 30 also includes a shield 34. Along the left and right direction, the shield 34 is connected to the outside of the main board 321 and extends downward relative to the baffle frame 32. The shield 34, the connecting plate 322 on the side near the shield 34 and the main board 321 together define the mounting groove 35. One of the two baffles 33 located on the outside is disposed in the mounting groove 35.

[0046] Understandably, the shield 34 is connected to the outside of the main board 321 and extends downwards from the main board 321. The shield 34, the connecting plate 322 on the side near the shield 34, and the main board 321 together define the mounting groove 35. The mounting groove 35 can provide an independent assembly space for the baffle 33, avoiding the risk of damage caused by the end of the baffle 33 near the main board 321 being directly exposed to the outside of the range hood 100. It can also shield the appearance of the connection between the baffle 33 and the main board 321, thereby improving the overall appearance quality. Moreover, the mounting groove 35 can limit the baffle 33 in both the left and right directions, thereby improving the stability of the baffle 33 after assembly and avoiding the risk of displacement of the baffle 33 due to airflow impact during long-term use.

[0047] Specifically, in combination Figures 3-5 and Figure 9As shown, the motherboard 321 includes a top support portion 324 and a side support portion 325. The top support portion 324 extends in the front-rear direction and is located below the top plate 11. Two connecting plates 322 are connected to the lower side of the top support portion 324, and a baffle 33 is connected to the lower side of the top support portion 324. The top support portion 324 is provided with mounting holes 3241. After fasteners pass through the mounting holes 3241, the top support portion 324 and the top plate 11 are connected as a whole. The side support portion 325 is connected to the rear end of the top support portion 324 and extends downward. The baffle 33 is connected to the front side of the side support portion 325. The side support portion 325 is provided with a snap-fit ​​portion 3251, which snaps into the front panel 12 of the housing 10.

[0048] In other words, the top support 324 is connected to the upper side of the baffle 33, and the side support 325 is connected to the rear side of the baffle 33. As arranged as above, the baffle frame 32 can establish a connection with the baffle 33 in different directions (i.e., the up and down direction and the front and back direction), which can effectively improve the connection reliability between the baffle frame 32 and the baffle 33.

[0049] The top support 324 is provided with mounting holes 3241. Fasteners can pass through the mounting holes 3241 and the top plate 11 in sequence along the vertical direction. This allows the top support 324 and the top plate 11 to be connected into a solid whole, and it is convenient to disassemble and reassemble multiple times and reuse, thereby improving the efficiency of later maintenance and replacement.

[0050] Furthermore, the snap-fit ​​portion 3251 on the side support 325 engages with the front panel 12 of the housing 10, thus connecting the side support 325 and the front panel 12 into a single unit. Compared to other connection methods (such as screwing or bonding), the snap-fit ​​connection eliminates the need for additional parts, avoiding unnecessary material consumption. It also provides sufficient retaining force to prevent the side support 325 from detaching from the top panel. Moreover, the snap-fit ​​connection structure is simple, reliable, and offers quick and easy disassembly and installation (allowing for rapid connection and separation of the side support 325 and the front panel 12), effectively reducing maintenance and replacement time and costs.

[0051] According to some optional embodiments of the present invention, combined with Figure 1 , Figure 2 and Figure 6 As shown, the front of the top plate 11 is provided with a front air curtain outlet 112 that extends in the left-right direction. The air curtain device 20 supplies air to the front air curtain outlet 112. At least a portion of the air guide 31 corresponds to and is connected to the portion of the front air curtain outlet 112 that extends in the front-back direction.

[0052] Specifically, the front of the top plate 11 is provided with a front air curtain outlet 112. The front air curtain outlet 112 can extend only in the left and right direction, or it can extend partly in the left and right direction and then extend in the front and back directions. That is, the front air curtain outlet 112 can at least exhaust air downward along the front edge of the top plate 11. In this way, an airflow barrier can be formed along the exhaust direction of the front air curtain outlet 112, thereby preventing the oil fumes from spreading from the open part on the front side of the top plate 11.

[0053] Since the baffle assembly 30 is located on the left and right sides of the housing 10, the air guide 31 on the baffle assembly 30 corresponds to the parts of the side air curtain outlet 111 and the front air curtain outlet 112 that extend in the front-back direction. This makes it easy for the air guide 31 to correspond to and connect with all the air curtain outlets on the left and right sides of the housing 10. With the above arrangement, the baffle assembly 30 can form a physical structure to block the oil fumes in the left and right directions. On the other hand, it can also make the air flowing through the air guide 31 flow along the extension direction of the baffle assembly 30, that is, to guide the air path more accurately and reduce the problem of disordered diffusion of the air at the output end due to insufficient wind power. This improves the formation effect of the airflow barrier on the left and right sides of the range hood 100, and thus improves the oil fume blocking effect of the air curtain device 20.

[0054] Specifically, in combination Figure 1 , Figure 2 and Figure 6 As shown, the air curtain device 20 includes a fan 21, an air duct component 22, and a control component 23. The air duct component 22 is connected to the front air curtain outlet 112 and the side air curtain outlet 111, respectively. The control component 23 is disposed between the fan 21 and the air duct component 22 to selectively control the air duct component 22 to deliver air to the front air curtain outlet 112 and the side air curtain outlet 111.

[0055] The control component 23 is directly connected to the output end of the fan 21. This allows the control component 23 to complete the air path distribution and on / off control before the air generated by the fan 21 enters the air duct component 22. 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 111 does not need air supply, the control component 23 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 21.

[0056] In addition, the air duct component 22 is connected to the front air curtain outlet 112 and the side air curtain outlet 111 respectively. The front air curtain outlet 112 and the side air curtain outlet 111 are set independently of each other.
