[0037] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0038] The terms “a,” “one,” and “the” are used to indicate the existence of one or more elements / components / etc.; the terms “include” and “have” are used to indicate an open-ended meaning of inclusion and to mean that there may be other elements / components / etc. in addition to the listed elements / components / etc.

[0039] This utility model embodiment provides an embedded range hood, such as Figure 1-18 As shown, the embedded range hood includes a housing assembly 1, a smoke collection hood 2, and a first fan assembly. The housing assembly 1 includes an independent exhaust chamber 11, a blowing chamber 12 for blowing air into the room, and a placement chamber 13 for placing items. The placement chamber 13 and the blowing chamber 12 are arranged side by side. The exhaust chamber 11 has a through hole at its bottom, the blowing chamber 12 has an air inlet at its top, and an air outlet 121 on its front side. The placement chamber 13 has an inlet and outlet for items to pass through on its front side. The smoke collection hood 2 is flexibly connected to the exhaust chamber 11 and has a working position extending out of the through hole and a non-working position retracted into the exhaust chamber 11. The first fan assembly is installed in the blowing chamber 12, with its air inlet end connected to the air inlet and its air outlet end connected to the air outlet 121. By setting the blowing chamber 12, a wide-area air outlet 121 is provided on the front side of the blowing chamber 12, which can laterally cover the left and right cooking near-field areas, such as... Figure 3 As shown, a lower airflow is used to reduce the perceived temperature for the user. In addition, a storage chamber 13 is set on the left and right sides of the air blowing chamber 104 for temporary storage of food. This is used to temporarily store food after cooking, and the ambient heat from the range hood helps to keep the food warm, preventing it from cooling down too quickly in the open space. At the same time, it does not occupy kitchen countertop area, saving countertop space. In addition, it reduces unnecessary movement for the user and improves cooking efficiency to a certain extent.

[0040] In a preferred embodiment of this utility model, such as Figure 1-18As shown, the housing assembly 1 includes a first housing 14 and a second housing 15 arranged from top to bottom. The bottom wall of the second housing 15 has a through hole. The first housing 14 and the second housing 15 are interconnected to form a smoke exhaust chamber 11. A second fan assembly is disposed within the first housing 14. A lifting assembly 3 connects the smoke hood 2 to the first housing 14 and the second housing 15. The smoke hood 2 is configured to have a working position extending outward from the through hole and a non-working position retracted into the second housing 15, driven by the lifting assembly 3. This application can quickly capture and exhaust cooking fumes, heat, and odors generated during cooking to the outside through the smoke exhaust chamber 11 and the second fan assembly. The smoke hood 2 extends or retracts from the bottom of the smoke exhaust chamber 11. When the range hood is turned off, the smoke hood 2 is stored inside the smoke exhaust chamber 11. When working, the smoke hood 2 is open, maximizing space utilization and aesthetics, saving space and creating a clean visual appearance. When not in use, the smoke hood is completely retracted into the cabinet or the main body, integrating seamlessly with the kitchen cabinets to form a flat surface. This makes the kitchen look cleaner and more spacious, avoids bumps and knocks, creates an effective negative pressure zone, captures cooking fumes at the source, and improves fume extraction efficiency.

[0041] In a preferred embodiment of this utility model, such as Figure 1-18 As shown, the front sidewall of the second housing 15 is recessed rearward on the side near the first housing 14 to form a mounting groove 151. At least one partition 152 is provided within the mounting groove 151, which can divide the inner cavity of the mounting groove 151 into a sealed blowing chamber 12 and at least one placement chamber 13 with an opening on the front side. The blowing chamber 12 and the placement chamber 13 are mutually isolated. In this application, a first fan for extracting oil fumes is provided inside the first housing 14, and the second housing 15 is used to house the fume hood 2 and the oil filter 7. Since the fume hood 2 has a triangular prism structure, when the fume hood 2 is housed at the rear of the second housing 12, the front part of the second housing 12 has a certain storage space. Its oil fume emission channel guides upward from the fume hood 2 and does not enter the mounting groove 151. Furthermore, since the smoke-collecting plate 4 can absorb most of the cooking fumes, the indoor air above the smoke-collecting plate 4, which is the air inlet area of ​​the first fan assembly, is generally not polluted. The first fan assembly can blow the ambient temperature above towards the user, providing a more comfortable cooking environment. Moreover, the forward-blowing air outlet 121 does not affect the smoke-collecting effect. In other words, the mounting slot 151 of this application fully utilizes the structural advantages of the second housing 12, adding a blowing chamber 12 and at least one placement chamber 13 with an opening on the front without affecting the smoke absorption. This not only reduces the user's perceived temperature but also utilizes the ambient heat from the range hood to help keep the food warm, preventing the food from cooling down too quickly in the open space. At the same time, it does not occupy kitchen countertop area, saving countertop space.

[0042] In a preferred embodiment of this utility model, such as Figure 1-3As shown, there are multiple air outlets 121, each extending along the length of the second housing 15. This allows the air blowing cavity 12 to form a... Figure 3 The wide air outlet area shown can cover the left and right cooking areas horizontally, achieving the effect of reducing the user's perceived temperature with a lower air volume.

[0043] In a preferred embodiment of this utility model, such as Figure 1-6 The lifting assembly 3 shown includes a drive component 31 and a guide component 32. The housing of the drive component 31 is fixedly connected to the first housing 14, and its drive end is fixedly connected to the smoke hood 2, which can drive the smoke hood 2 to move between the working position and the non-working position. The guide component 32 is connected to the first housing 14 and the smoke hood 2 to enable the smoke hood 2 to move linearly up and down. The drive component 31 can be an electric actuator, which uses the working principle of the electric actuator to drive the lifting and lowering of the smoke hood 2, and has a simple structure. There are two sets of guide components 32. Each set of guide components 32 includes a slide rail 321 and a slider 322. The slide rail 321 is connected to the inside of the range hood housing 100, and the slider 322 is connected between the slide rail 321 and the smoke hood 2. The movement between the slide rail 321 and the slider 322 ensures that the smoke hood 2 moves linearly in the vertical direction, making the operation of the smoke hood 2 more stable when the range hood is opened or closed.

[0044] In a preferred embodiment of this utility model, such as Figure 11-18 The housing assembly 1 shown is also connected to a smoke-collecting plate 4 and a flipping assembly 5 for driving the smoke-collecting plate 4 to rotate synchronously with the smoke collection hood 2. By using the movement of the smoke collection hood 2 to drive the opening and closing of the smoke-collecting plate 4, the structure is not only compact, but also enables the smoke collection hood 2 and the smoke-collecting plate 4 to form an effective smoke-collecting shape. This solves the problem of limited smoke-collecting shape in existing single-motor driven linkage mechanisms, especially the poor smoke-collecting shape of side-suction mechanisms, which affects the smoke-collecting effect.

[0045] In a preferred embodiment of this utility model, such as Figure 11-18The embedded range hood shown also includes a flipping assembly 5 for driving the smoke collection plate 4 to flip. The flipping assembly 5 includes a support assembly 51, a hinge assembly 52, and a transmission mechanism 53. The support assembly 51 includes a first support 511 connected to the rear side of the first housing 14, a second support 512 connected to the bottom of the smoke collection hood 2, and a third support 513 connected to the bottom of the front side of the second housing 15. The hinge assembly 52 is hinged between the third support 513 and the smoke collection plate 4. The transmission mechanism 53 is connected to the first support 511, the second support 512, and the hinge assembly 52, and is used to transmit the movement of the smoke collection hood 2 to the hinge assembly 52. ​​The smoke collection hood 2 can drive the second support 512 to move up and down, and the second support 512 drives the transmission mechanism 53 to move. The movement of the transmission mechanism 53 further drives the hinge assembly 52 and the smoke collection plate 4 on it to flip. When the range hood is off, the smoke hood 2 and the smoke collection plate 4 retract into the range hood housing 1, becoming completely invisible. The entire front, sides, and bottom of the range hood blend seamlessly with the cabinet 100, resulting in a minimalist and aesthetically pleasing design. When the range hood is on, the smoke hood 2 descends, closing the distance to the point of smoke generation and capturing the smoke before it spreads. A negative pressure zone is created: a low but powerful negative pressure airflow is formed above the cookware. The smoke collection plate 4 blocks lateral escape, effectively preventing smoke from spreading to the left and right sides during its ascent—a weakness of traditional top-mounted and single-lift models. The smoke hood, smoke collection plate, and cooktop together form a three-sided enclosed "invisible smoke collection chamber," firmly locking the smoke within this chamber and forcing it to enter the range hood's air duct only upwards, improving smoke extraction efficiency.

[0046] In a preferred embodiment of this utility model, such as Figure 11-18The transmission mechanism 53 shown includes: a first transmission component 531 and a second transmission component 532. The first transmission component 531 is hinged between the first support 511 and the second support 512. The second transmission component 532 is hinged between the first support 511 and the hinge. The end of the first transmission component 531 near the first support 511 and the second transmission component 532 are fixedly connected. The lifting and lowering movement of the smoke hood 2 drives the first transmission component 531 to move through the second support 512. The first transmission component 531 simultaneously drives the second transmission component 532 to move. The second transmission component 532 further drives the hinge component 52 and the smoke collection plate 4 connected thereto to rotate. In this application, a first transmission component 531 is connected between a first support 511 and a second support 512, and a second transmission component 532 is connected between the first transmission component 531 and a hinge 521. The lifting and lowering movement of the smoke hood 2 drives the second support 512 and the first transmission component 531 to lift and lower. The lifting and lowering of the first transmission component 531 drives the second transmission component 532 to rotate and lift around the first support 511 as the hinge point. In this way, the second transmission component 532 can drive the hinge component 52 to rotate. The hinge component 52 continues to rotate around the third support 513, and at the same time drives the smoke collection plate 4 to rotate to open or close.

[0047] In a preferred embodiment of this utility model, such as Figure 11-18The first transmission assembly 531 shown includes a first main rod 5311 and a first transmission rod 5312. One end of the first main rod 5311 is hinged to the first support 511, and the first transmission rod 5312 is hinged between the other end of the first main rod 5311 and the second support 512. The second transmission assembly 532 includes a second main rod 5321 and a second transmission rod 5322. One end of the second main rod 5321 is hinged to the first support 511, and the second transmission rod 5322 is hinged between the other end of the second main rod 5321 and the hinge assembly 52. ​​A connecting block 533 is provided between the ends of the first main rod 5311 and the second main rod 5321 near the first support 511 to realize the motion transmission between the first transmission assembly 531 and the second transmission assembly 532. The range hood of this application also includes an oil filter 7, which can move synchronously with the smoke collection hood 2. Specifically, the first transmission assembly 531, the second transmission assembly 532, and the corresponding support assembly 51 are two sets symmetrically distributed on both sides of the oil filter 7. The first support 51 includes a first base plate 5111 fixed to the rear side of the first housing 14 and two first lugs 5112 connected to both sides of the first base plate 5111. The second support 512 includes a second base plate 5121 fixed to the bottom of the smoke collection hood 2 and two second lugs 5112 connected to both sides of the second base plate 5121. 122, the top ends of the first main rod 5311 and the second main rod 5321 are respectively hinged to two first lugs 5112 and can rotate around the corresponding hinge points. The second transmission rod 5322 is hinged between the bottom end of the second main rod 5321 and the hinge assembly 52. ​​The top end of the first transmission rod 5312 is hinged to the bottom end of the first main rod 5311. The bottom end of the first transmission rod 5312 is hinged to the second lug 5122 on the side away from the oil mesh 7. The other of the two second lugs 5122 is hinged to the rear side of the oil mesh 7.Since the first substrate 5111 is fixed to the rear side of the first housing 14 and the second substrate 5121 is fixed to the bottom of the smoke hood 2, the smoke hood 2 can drive the second ear piece 5122 and the first transmission rod 5312 on it to move during its up and down movement. The first transmission rod 5312 simultaneously drives the first main rod 5311 to rotate. Since the first main rod 5311 and the second main rod 5321 are fixedly connected by the connecting plate 53, the second main rod 5321 and the first main rod 5311 move synchronously. Then, the second main rod 5321 drives the second transmission rod 5322 to move accordingly. The movement of the second transmission rod 5322 drives the hinge 521 to rotate. During the descent to the working position, the movement of the second transmission rod 5322 drives the hinge 521 and the smoke-collecting plate 4 to rotate counterclockwise and open the smoke inlet. As the smoke hood 2 rises, the movement of the second transmission rod 5322 drives the hinge 521 and the smoke-collecting plate 4 to rotate clockwise and close the smoke inlet. As the smoke hood 2 retracts into the non-working position within the second housing 15, the smoke-collecting plate 4 completely closes the smoke inlet. Simultaneously, the second transmission rod 5322 drives the hinge 521 to move to the front end of the third support 513, applying forward and downward pressure to the hinge 521, achieving pre-tension on both sides of the smoke-collecting plate 4 and preventing the smoke-collecting plate 4 from opening automatically. Thus, when the smoke machine is running, the smoke hood 2 descends to the working position, the smoke-collecting plate 4 opens to its maximum angle, and the oil screen 7 flips and descends under the drive of the linkage mechanism, together forming the smoke-collecting area. When the smoke machine is turned off, the smoke collection hood 2 rises into the main body of the smoke machine, the smoke gathering plate 4 flips and closes to a horizontal position, and the oil screen 7 flips into the main body of the smoke machine under the action of the linkage mechanism, thus achieving the overall appearance effect.

[0048] Furthermore, the oil mesh 7 of this application always blocks the smoke inlet, which can filter and separate the inhaled oil fumes, and also disperse and distribute the inhaled airflow more evenly, avoiding the formation of eddies or turbulence in the airflow at the air inlet, thereby allowing the fan to work more smoothly and efficiently, and helping to reduce noise and optimize airflow organization. Since the transmission mechanism 53 also needs to connect the smoke hood 2 and the hinge 521, in order to avoid interference between the transmission mechanism 53 and the oil mesh 7, this application uses two supports 511, 512, and 513. One end of the oil mesh 7 is hinged between the two second supports 512, and the other end of the oil mesh 7 is hinged between the two third supports 53. This cleverly avoids interference between the oil mesh 7 and the transmission mechanism 53, and simultaneously realizes the simultaneous operation of the three actions of raising and lowering the smoke hood 2, flipping the oil mesh 7, and flipping the smoke collection plate 4.

[0049] like Figure 11-18The hinge assembly 52 shown includes a hinge 521. The third support 513 includes a third base plate 5131 and a third ear plate 5132 connected to the bottom of the range hood housing 1. The third base plate 5131 has a protrusion 51311 on the side near the first support 511 for limiting the rotation of the hinge 521. The protrusion 51311 not only increases the structural strength of the third support 513, but also limits the rotation of the hinge 521. When the hinge 521 and the protrusion 3311 come into contact, the smoke-collecting plate 4 is fully opened, ensuring the shape of the smoke-collecting area and improving the smoke-collecting effect.

[0050] In a preferred embodiment of the present invention, such as Figure 1-9 The oil mesh 7 shown is provided with a first connecting block 71 for hinged connection with the second support 512, and a second connecting block 72 is provided on the side of the oil mesh 7 near the third support 513. The third support 513 is provided with a connecting rod 5133 for hinged connection with the second connecting block 72. The second support 512 includes a second base plate 5121 fixed to the bottom of the smoke hood 2 and two second lugs 322 connected to both sides of the second base plate 5121. The top of the first transmission rod 5312 is hinged to the bottom of the first main rod 5311. The top and bottom of the first transmission rod 5312 are hinged to the second lug 322 on the side away from the oil mesh 7. The other of the two second lugs 322 is hinged to the first connecting block 71. The third support 513 is also provided with a fourth lug on the side near the oil mesh 7. The fourth lug is hinged to a connecting rod 5133. The connecting rod 5133 is hinged to the second connecting block 72. In this way, during the lifting and lowering of the smoke hood 2, the second support 512 can drive the rear end of the oil mesh 7 to rotate around the hinge point between the two third supports 513, ensuring that the oil mesh 7 always blocks the smoke inlet and improves the smoking effect.
