Technical Field
[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a smoke-blocking mechanism and a fume treatment device. Background Technology
[0002] Range hoods are widely used because they quickly remove cooking fumes, improving the cooking environment. When installing a range hood, it's essential to maintain sufficient distance between it and the cooktop to accommodate pots and pans. However, when cooking produces a large amount of fumes, some may escape from the sides, resulting in a less effective improvement in the kitchen environment.
[0003] In related technologies, some range hoods have smoke baffles on the left and right sides. These baffles extend into the frame of the range hood to collect smoke and reduce its escape. However, after collecting the smoke, grease accumulates on the surface of the baffles, requiring manual cleaning each time, resulting in a poor user experience. Utility Model Content

[0024] The smoke-blocking mechanism of this utility model
[0025] The oil fume treatment device of this utility model can play a role in blocking smoke when the smoke baffle slides along the slide rail to at least partially extend out of the slide rail. Since the cleaning component is connected to the support component and keeps in contact with the smoke baffle, the cleaning component scrapes the surface of the smoke baffle during the process of the smoke baffle extending and retracting into the slide rail, thereby removing the oil stains on the smoke baffle. The cleaning of the smoke baffle is automatically completed during its movement, which not only eliminates the need for manual cleaning, but also eliminates the need for additional operation during the cleaning process, resulting in a good user experience.

It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0044] This embodiment provides an oil fume treatment device, which can be a range hood, integrated stove, etc. The following description uses a range hood as an example of an oil fume treatment device.
[0045] like Figure 1 and Figure 2 As shown, the fume treatment device includes a fume hood 11 and a fan. The fume hood 11 encloses a fume collection chamber 113 with an air inlet 111, and the fan is installed inside the fume collection chamber 113. When the fan operates, it creates a negative pressure in a certain area inside the fume collection chamber 113 and outside the air inlet 111, thereby drawing the fumes generated during cooking into the fume collection chamber 113 and ultimately exhausting them outdoors. Figure 1 As shown, the air inlet 111 of the smoke collection chamber 113 is located on the lower side of the smoke collection hood 11. The air inlet 111 includes air inlet a1111 and air inlet b1112. Air inlet a1111 is located in the middle area of the smoke collection chamber 113 in the left-right direction, and there are two air inlets b1112, located on the left and right sides of air inlet a1111 respectively. Optionally, both air inlet a1111 and air inlet b1112 are provided with mesh plates. The mesh plates can filter out larger impurities, preventing them from being sucked into the fan and causing damage. Optionally, the mesh plate at air inlet a1111 is set as an inverted "V" shape, and the mesh plate at air inlet b1112 is set horizontally. It is understood that in other embodiments, the shape, angle, etc., of the mesh plate at air inlet 111 can be flexibly set according to requirements and are not limited here.
[0046] There is a certain distance between the fume extraction device and the stove. When cooking produces a large amount of fumes, some of the fumes will escape from the sides, resulting in poor kitchen environment improvement. Therefore, if... Figure 2 and Figure 3 As shown, the fume treatment device also includes a smoke-blocking mechanism, which is located on the side of the air inlet 111. The smoke-blocking mechanism includes a support assembly 12 and a smoke-blocking plate 20. The support assembly 12 is connected to the smoke collection hood 11 and forms a slide 121. The smoke-blocking plate 20 can move along the slide 121 to retract into the slide 121 or at least partially extend out of the slide 121. In this embodiment, the support assembly 12 is located inside the smoke collection hood 11. When the smoke-blocking plate 20 extends out of the slide 121, at least part of it can extend outside the smoke collection hood 11, thereby playing the role of blocking smoke and concentrating the negative pressure outside the smoke collection hood 11. Figure 2 The area within the middle dashed line and Figure 3 The area between the two smoke baffles 20 is a negative pressure area, which improves the smoke extraction effect of the fume treatment device. In other embodiments (not shown), the support component 12 can also be connected to the outside of the smoke collection hood 11, as long as it is ensured that when the smoke baffle 20 extends out of the slide 121, it can protrude from the outer surface of the smoke collection hood 11, thereby playing the role of blocking smoke and concentrating negative pressure.
[0047] like Figure 2 and Figure 3As shown, the fume treatment device includes two smoke-blocking mechanisms, which are respectively located on the left and right sides of the air inlet 111. When both smoke-blocking plates 20 extend out of the fume collection hood 11 simultaneously, the negative pressure area can be better concentrated above the stove, preventing fumes from escaping from the left and right sides and greatly improving the smoke extraction effect. Furthermore, the smoke-blocking plates 20 on the left and right sides have minimal impact on the user's cooking operations in front of the fume treatment device. It is understood that during the use of the fume treatment device, depending on the distribution of cooking fumes, only one smoke-blocking plate 20 can extend out of the fume collection hood 11, while the other smoke-blocking plate 20 remains retracted within the support assembly 12, increasing the flexibility of the fume treatment device. In other embodiments, the fume treatment device may also be equipped with one, three, or more smoke-blocking plates 20; no specific limitation is made here. In this embodiment, the smoke-blocking plates 20 are arranged perpendicular to the left and right direction.
[0048] To ensure that the smoke baffle 20 can extend smoothly out of the smoke collection hood 11, such as Figures 2-5 As shown, the smoke hood 11 is provided with a clearance opening 112 located below the support assembly 12. The smoke baffle 20 extends from the lower end of the slide rail 121 and passes through the clearance opening 112 to extend outside the smoke hood 11. The smoke baffle 20 includes a baffle body 21 and a stop portion 22 provided on the upper end of the baffle body 21. The cross-sectional area of the stop portion 22 is larger than the cross-sectional area of the baffle body 21. The stop portion 22 is used to cooperate with the smoke hood 11 or the support assembly 12 to limit its movement and prevent the smoke baffle 20 from falling off the fume treatment device.
[0049] In some embodiments, such as Figure 5 As shown, the cross-sectional area of the clearance opening 112 is larger than the cross-sectional area of the baffle body 21 and smaller than the cross-sectional area of the stop portion 22. This allows the smoke hood 11 to limit the stop portion 22 while allowing the baffle body 21 to extend out of the smoke hood 11, thus preventing the smoke baffle 20 from falling off. In this solution, only the size of the clearance opening 112 needs to be set within a suitable range, without adding other components, thereby simplifying the structure of the frame assembly and reducing the cost of the fume treatment device. Optionally, the smoke hood 11 is provided with an arc portion 114 located below the support assembly 12, and there is a certain gap between the arc portion 114 and the lower end of the support assembly 12. In this solution, when the stop portion 22 stops at the clearance opening 112 (e.g. Figure 5 As shown), the smoke baffle 20 can also be manually moved to swing left and right, thereby improving the flexibility of its use. In other embodiments, such as... Figure 6 As shown, the lower end of the support component 12 is fitted to the corresponding part of the smoke hood 11. In this design, the stop part 22 is always located within the slide rail 121, thus preventing the smoke baffle 20 from getting stuck when it rises due to not being aligned with the slide rail 121. In some embodiments, such as Figure 7As shown, the support assembly 12 includes a limiting part 1224, which is located at the lower end of the slide rail 121 and protrudes into the slide rail 121. A through hole 1225 is provided on the limiting part 1224, through which the baffle body 21 can pass. The limiting part 1224 can stop the stop part 22. This not only reliably limits the smoke baffle 20, preventing it from falling out of the frame assembly, but also ensures that the stop part 22 remains within the slide rail 121, thus preventing the smoke baffle 20 from jamming when it rises and not aligning with the slide rail 121.
[0050] After the smoke baffle 20 extends out of the smoke collection hood 11 and performs its smoke-blocking function, oil droplets will accumulate on its surface. Manual cleaning is time-consuming and laborious, resulting in a poor user experience. In response, such as... Figure 2 and Figure 3 As shown, the smoke-blocking mechanism also includes a cleaning component 50, which is connected to the support assembly 12 and disposed on the side of the smoke-blocking plate 20. The cleaning component 50 abuts against the smoke-blocking plate 20 and is used to clean the smoke-blocking plate 20. During the process of the smoke-blocking plate 20 extending and retracting into the slide rail 121, the cleaning component 50 scrapes the surface of the smoke-blocking plate 20, thereby removing the oil stains on the smoke-blocking plate 20. The cleaning of the smoke-blocking plate 20 is completed automatically during its movement, which not only eliminates the need for manual cleaning, but also eliminates the need for additional operation during the cleaning process, resulting in a good user experience. In addition, the fume treatment device does not need to configure a drive structure for the cleaning component 50, resulting in a simple structure and low cost.
[0051] It should be noted that, for the fume treatment device, the cleaning component 50 can be directly installed on the support assembly 12, or it can be installed on the fume hood 11, as long as it can abut against the fume baffle 20 and clean the fume baffle 20.
[0052] like Figure 2 and Figure 3 As shown, cleaning elements 50 are provided on both sides of the smoke baffle 20, allowing for simultaneous cleaning of both sides of the smoke baffle 20. In some embodiments, at least two cleaning elements 50 are provided on the same side of the smoke baffle 20, and these at least two cleaning elements 50 are spaced apart along the direction of movement of the smoke baffle 20. With this arrangement, as the smoke baffle 20 slides along the slide rail 121, multiple cleaning elements 50 can clean the smoke baffle 20 multiple times, thereby improving the cleaning effect. The spaced arrangement of multiple cleaning elements 50 reduces the total contact area between the cleaning elements 50 and the smoke baffle 20, thus reducing the resistance to the movement of the smoke baffle 20 during the cleaning process.
[0053] In this embodiment, the number of cleaning components 50 on both sides of the smoke baffle 20 is the same, thereby ensuring balanced force on both sides of the smoke baffle 20 during movement. In some embodiments, the number of cleaning components 50 on the side of the smoke baffle 20 closer to the air inlet 111 is greater than the number of cleaning components 50 on the side away from the air inlet 111, thereby ensuring that the overall cleaning capacity on both sides of the smoke baffle 20 matches the degree of dirt on the smoke baffle 20, reducing manufacturing costs while ensuring good cleaning effect. In this embodiment, multiple cleaning components 50 on the same side of the smoke baffle 20 are evenly arranged from top to bottom. In some embodiments, the arrangement density of multiple cleaning components 50 on the same side of the smoke baffle 20 gradually increases from top to bottom. It is understandable that during the process of the smoke baffle 20 completing its smoke-blocking task and moving upward along the slide 121, all positions of the smoke baffle 20 will come into contact with the cleaning components 50 arranged below, while only the upper part of the smoke baffle 20 will come into contact with the cleaning components 50 arranged above. By setting the arrangement density of the cleaning components 50 to gradually decrease from bottom to top, the number of cleaning components 50 can be reduced while ensuring the cleaning effect, thereby reducing manufacturing costs.
[0054] In this embodiment, the cleaning component 50 is at least partially made of a flexible material. Therefore, during the movement of the smoke baffle 20 along the slide 121, the cleaning component 50 is always in contact with the smoke baffle 20, and it can adaptably deform to avoid jamming during movement. For example, if the sliding direction of the smoke baffle 20 deviates slightly within the slide 121, or if the oil stains adhering to the smoke baffle 20 cannot be scraped off by a single cleaning component 50, the movement of the smoke baffle 20 may become jammed. In this case, the cleaning component 50 can adaptably deform elastically to allow the smoke baffle 20 to pass smoothly, preventing jamming. It should be noted that oil stains that cannot be cleaned directly by a single cleaning component 50 can be removed by multiple scrapings from multiple cleaning components 50. Optionally, the cleaning component 50 may be configured such that only the portion in contact with the smoke baffle 20 is made of a flexible material, or only the portion connected to the support assembly 12 is made of a flexible material, or the entire cleaning component 50 may be made of a flexible material; no specific limitations are made here. Alternatively, the flexible material can be rubber, nylon, PP, etc.
[0055] like Figures 2-5 As shown, the cleaning component 50 can swing along the movement direction of the smoke baffle 20 under the action of the smoke baffle 20. On the one hand, during the reciprocating motion of the smoke baffle 20, the cleaning component 50 can contact the smoke baffle 20 at different angles, thereby improving the cleaning effect; on the other hand, the relative angle between the cleaning component 50 and the smoke baffle 20 can be adaptively adjusted according to the movement direction of the smoke baffle 20, which can avoid excessive scratching force and damage to the smoke baffle 20.
[0056] In this embodiment, as Figure 4 and Figure 5As shown, the cleaning component 50 includes a connecting portion 51 and a scraper portion 52. The scraper portion 52 is made of a flexible material, with one end connected to the connecting portion 51 and the other end abutting against the smoke baffle 20. The connecting portion 51 is rotatably connected to the support assembly 12, thereby allowing the scraper portion 52 to swing along the movement direction of the smoke baffle 20. Specifically, when the smoke baffle 20 moves upward along the slide 121 from the position extending out of the smoke collection hood 11 (i.e., from the lowest point), the smoke baffle 20 applies an upward force to the scraper portion 52, causing the cleaning component 50 to swing upward to... Figure 4 As shown, during the process of the smoke baffle 20 rising to the retracted position, the cleaning component 50 maintains this posture. In this posture, the angle between the scraper portion 52 and the direction of movement of the smoke baffle 20 is an obtuse angle, resulting in low resistance during the cleaning process and minimizing the risk of scratching or damaging the smoke baffle 20. When the smoke baffle 20 moves downward from the retracted position (i.e., the highest point), the smoke baffle 20 exerts a downward force on the scraper portion 52, causing the cleaning component 50 to... Figure 4 The state swings downwards to Figure 5 As shown, the cleaning component 50 maintains this posture as the smoke baffle 20 descends to its lowest point. In this posture, the angle between the scraper part 52 and the direction of movement of the smoke baffle 20 is an obtuse angle, resulting in low resistance during the cleaning process and making it less likely to scratch the smoke baffle 20.
[0057] In this embodiment, the cleaning component 50 is constructed as a long strip extending front to back. The scraper portion 52 abuts against the smoke baffle 20 along the front to back, thereby cleaning the entire surface of the smoke baffle 20. In some embodiments, the cleaning component 50 has an angle in the front to back direction, for example, the cleaning component 50 is higher in the front and lower in the back. Therefore, the oil scraped off by the scraper portion 52 can flow backward along the scraper portion 52 and eventually drip from the rear end of the scraper portion 52 into the oil cup inside the smoke collection hood 11, preventing the cleaning component 50 from becoming clogged with oil and unable to move after long-term use. Of course, in order to better clean the smoke baffle mechanism, it can also be disassembled for deep cleaning after a certain period of use.
[0058] like Figure 2 and Figure 3 As shown, the support assembly 12 includes two support plates 122, which form a slide 121. The two support plates 122 respectively cover both sides of the smoke baffle 20. On the one hand, the support plates 122 cover the sides of the smoke baffle 20, preventing oil fumes inside the smoke hood 11 from depositing on the smoke baffle 20; on the other hand, the slide 121 formed by the two support plates 122 facilitates the insertion of various cleaning components 50 and the smoke baffle 20 into the slide 121. Optionally, the two support plates 122 can be fixed together by fasteners, snap-fitting, welding, etc., which are not specifically limited here.
[0059] Optionally, in some embodiments, the front and rear ends of the support plate 122 abut against the front inner wall and the thick inner wall of the smoke hood 11, respectively. This solution can also seal the front and rear ends of the slide 121. In this case, the entire slide 121 is only open at the lower end, thereby improving the sealing performance of the slide 121 and preventing oil fumes from entering the slide 121. No additional parts are needed, and the structure is simple and easy to install. In some embodiments, the support assembly 12 also includes end plates, which are connected to the front and rear ends of the two support plates 122, thereby sealing the front and rear ends of the slide 121. In this case, the entire slide 121 is only open at the lower end, thereby ensuring that the lower end of the smoke baffle 20 can extend out of the slide 121, and sealing the slide 121 as well as possible to prevent oil fumes from entering the interior of the slide 121.
[0060] In order to achieve a rotatable connection between the connecting part 51 and the support assembly 12, such as Figure 4 and Figure 5 As shown, a limiting groove 1221 is provided on the support component 12. The limiting groove 1221 has an opening on the side facing the smoke baffle 20. The connecting part 51 is disposed in the limiting groove 1221 and rotates with the groove wall of the limiting groove 1221. The scraper part 52 extends out of the opening from the limiting groove 1221 to abut against the smoke baffle 20. In this embodiment, by having the connecting part 51 directly rotate with the limiting groove 1221, the cleaning part 50 can swing along the movement direction of the smoke baffle 20, while eliminating the need for bearings and other components, resulting in a simple structure and low cost. In this embodiment, each support plate 122 has a limiting groove 1221 on the side facing the smoke baffle 20 to install the cleaning part 50 on both sides of the smoke baffle 20. The cross-section of the limiting groove 1221 is arc-shaped, and the cross-section of the connecting part 51 is circular, thereby ensuring smooth rotation between the two. Optionally, at least one end of the limiting groove 1221 in the front-back direction passes through the support plate 122, and the cleaning component 50 can be inserted into the limiting groove 1221 in the front-back direction, thereby improving the ease of assembly of the cleaning component 50.
[0061] like Figure 4 and Figure 5As shown, the support assembly 12 is provided with a first limiting part 1222 and a second limiting part 1223. The first limiting part 1222 and the second limiting part 1223 are respectively provided on both sides of the swing direction of the cleaning component 50 and are used to limit the swing range of the cleaning component 50. In this embodiment, the first limiting part 1222 and the second limiting part 1223 can respectively stop the scraper part 52, thereby limiting the swing angle of the cleaning component 50, preventing the scraper part 52 from rotating to a state parallel to the smoke baffle 20, and ensuring that the scraper part 52 is always in contact with the smoke baffle 20. In this embodiment, the support plate 122 is provided with a trapezoidal groove. The upper bottom side of the trapezoidal groove faces the opening of the limiting groove 1221, and the lower bottom side faces the smoke baffle 20. The two waists of the trapezoidal groove extend from the opening of the limiting groove 1221 toward the smoke baffle to respectively form the first limiting part 1222 and the second limiting part 1223. In this embodiment, the first limiting part 1222 and the second limiting part 1223 are formed by directly opening a trapezoidal groove on the support plate 122. This not only simplifies the structure but also ensures reliable positioning of the scraper part 52. Optionally, the trapezoidal groove is an isosceles trapezoid, thereby ensuring uniform oil scraping effect of the scraper part 52 during the rising and falling of the smoke baffle 20.
[0062] In this embodiment, the smoke-blocking mechanism further includes a drive component, which is connected to the support component 12 and can drive the smoke-blocking plate 20 to reciprocate. In some embodiments (not shown), the drive component includes an electric actuator, the output end of which is connected to the smoke-blocking plate 20, thereby driving the smoke-blocking plate 20 to reciprocate along the slide rail 121. In some embodiments, the drive component includes a magnetic mechanism. Compared to an electric actuator, a magnetic mechanism has lower cost, thereby reducing the overall manufacturing cost of the fume treatment device; and the magnetic mechanism is smaller in size, thereby improving the structural compactness of the fume treatment device. Optionally, as... Figure 2 As shown, the magnetic mechanism includes an electromagnet 31, which is disposed on the top of the slide rail 121 (fixed to the support assembly 12). The smoke baffle 20 is made of ferromagnetic material, and the electromagnet 31 can generate a magnetic attraction force on the smoke baffle 20. By changing the magnitude or direction of the magnetic force of the electromagnet 31, the magnitude and direction of the force exerted by the electromagnet 31 on the smoke baffle 20 can be changed, thereby driving the smoke baffle 20 to slide along the slide rail 121. In other embodiments, the electromagnet 31 can be installed on the top of the smoke baffle 20, and a ferromagnetic component can be installed on the top of the slide rail 121, with the electromagnet 31 and the ferromagnetic component attracting each other. In another embodiment, the magnetic mechanism includes two electromagnets 31, one of which is fixed to the top of the slide rail 121, and the other is connected to the top of the smoke baffle 20, with the two electromagnets 31 able to generate a magnetic attraction force on each other.
