Description

Technical Field

[0001] This utility model relates to the field of integrated stove technology, and in particular to a concealed smoke guide plate structure for integrated stoves. Background Technology

[0002] Currently, integrated cooktops on the market generally adopt a hidden smoke guide plate design in pursuit of aesthetics and functionality. In standby mode, the smoke guide plate can cover the smoke chamber, keeping the cooktop surface flat and simple in appearance; when working, the smoke guide plate will open to guide the fumes and prevent them from spreading.

[0003] Existing concealed smoke deflector structures require two or more independent drive motors and transmission mechanisms to simultaneously achieve the flipping of the smoke deflector and the movement of the auxiliary slide plate when opening and closing. This not only increases the complexity of the internal structure, increases manufacturing costs and assembly difficulty, but also increases potential failure points and reduces the long-term reliability of the product. Utility Model Content

[0004] The purpose of this invention is to reduce the complexity of the internal structure of the concealed smoke guide plate, manufacturing cost and assembly difficulty, reduce potential failure points, and improve the long-term reliability of the product.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concealed smoke guide plate structure for an integrated stove, including a range hood, wherein smoke inlets are symmetrically arranged on both sides of the bottom surface of the range hood, and an oil collection box is embedded in the center of the bottom surface; The range hood has rotatably connected smoke guide plates on both sides near the oil collection box, and slidably connected sliding plates on both sides away from the oil collection box. An oil collecting plate is fixed to the top wall of the smoke guide plate, and the oil collecting plate forms an inclined oil guiding surface when the smoke guide plate is flipped open. The range hood is equipped with a drive assembly on its outer wall. The drive assembly synchronously drives the smoke guide plate to flip and the slide plate to slide via a single drive motor.

[0006] As a further description of the above technical solution: the smoke guide plate is rotatably connected to the inner wall of the range hood via a rotating rod, and one end of the rotating rod passes through the side wall of the range hood; The drive assembly includes a first driven gear and a second driven gear fixed to the outer ends of two rotating rods.

[0007] As a further description of the above technical solution: the first driven gear meshes with the first driving gear, and the second driven gear meshes with the second driving gear; The first drive gear and the second drive gear mesh with each other and are both rotatably connected to the outer wall of the range hood; The output end of the drive motor is fixed coaxially with the first drive gear.

[0008] As a further description of the above technical solution: the drive assembly also includes a rack; The rack is provided with two sets, which mesh with the first driven gear and the second driven gear respectively; One end of the rack is fixed with an L-shaped rod, and the other end of the L-shaped rod is fixedly connected to the slide plate.

[0009] As a further description of the above technical solution: the bottom wall of the range hood is fixed with a support plate, and the support plate has sliding holes; The L-shaped rod passes through the sliding hole and slides in connection with the support plate, thereby enabling the linear displacement of the slide plate.

[0010] As a further description of the above technical solution: the drive motor is mounted on the outer wall of the range hood via an L-shaped plate; After receiving power from the drive motor, the first drive gear drives the first driven gear to achieve the flipping motion of the smoke guide plate on the same side, and at the same time, the second drive gear and the second driven gear drive the smoke guide plate on the other side to flip in the opposite direction.

[0011] As a further description of the above technical solution: when the first driven gear rotates clockwise, it drives the meshing rack to move outward in a straight line; When the second driven gear rotates counterclockwise, it drives the meshing rack to move outward in a straight line in the opposite direction; Two sets of racks are connected to the slide plates via L-shaped rods, enabling the slide plates on both sides to slide synchronously and separately.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. By using a drive motor, the synchronous reverse rotation of the two smoke guide plates and the synchronous opposite sliding of the two slide plates are achieved, which greatly simplifies the complexity of the drive system and significantly reduces hardware costs and assembly complexity compared to multi-motor solutions.

[0013] 2. An oil collection plate has been added to the top wall of the smoke guide plate. When the smoke guide plate is flipped open, the oil collection plate will naturally form an inclined angle, allowing the condensed and adsorbed oil during cooking to flow automatically to a lower position by gravity and eventually drip into the oil collection box. This achieves automatic oil diversion and collection, reduces oil residue in the cavity, and facilitates users' later cleaning and maintenance. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a hidden smoke guide plate structure for an integrated stove, including a range hood 10. To improve the efficiency of smoke extraction, rectangular smoke inlets 101 are symmetrically arranged on the left and right sides of the bottom of the range hood 10. An oil collection box 11 is also embedded in the center of the bottom to collect waste oil generated during cooking.

[0018] In order to cover the smoke inlet 101 and achieve the smoke guiding function when not in operation, the range hood 10 is provided with a smoke guide plate 12 and a sliding plate 13. Specifically, two smoke guide plates 12 with the same structure are rotatably installed on both sides of the range hood 10 near the central oil collection box 11; while on the side away from the oil collection box 11, two sliding plates 13 are slidably connected. In the standby state, the smoke guide plate 12 and the sliding plate 13 work together to completely cover the smoke inlet 101.

[0019] In order to achieve effective collection of oil stains, an oil collection plate 23 is fixed on the top wall of each smoke guide plate 12, that is, the side facing the inside of the range hood. The coordinated movement of all these moving parts is controlled by a drive assembly installed on the outer wall of the range hood 10.

[0020] The drive assembly is the driving component that enables the concealment and unfolding functions of this structure. The two smoke guide plates 12 are not directly fixed to the body, but are rotatably connected to the inner wall of the range hood 10 through their respective rotating rods 14. One end of each rotating rod 14 passes through the side wall of the range hood 10 and extends to the outside of the body so as to dock with the drive assembly. On the rods of the two rotating rods 14 that extend outside the body, a first driven gear 15 and a second driven gear 16 are fixedly installed respectively. These two driven gears directly participate in the rotation control of the smoke guide plates 12.

[0021] The driving force comes from the drive motor 20, which is fixed to the outer wall of the range hood 10 by the L-shaped plate 19. The output shaft of the drive motor 20 is connected to the first drive gear 17, which simultaneously meshes with the first driven gear 15 and the second drive gear 18. The second drive gear 18 further meshes with the second driven gear 16. This gear transmission layout can effectively distribute the power of the single drive motor 20 to the two smoke guide plates 12, enabling them to rotate in opposite directions.

[0022] In order to drive the sliding plate 13 to slide, two support plates 21 are fixed on the bottom wall of the range hood 10. Each support plate 21 is provided with a sliding hole. An L-shaped rod 22 passes through the sliding hole and can slide freely in it. One end of the L-shaped rod 22 is fixedly connected to the sliding plate 13, and the other end is fixedly connected to a toothed rod 24. The two toothed rods 24 are respectively meshed with the first driven gear 15 and the second driven gear 16.

[0023] Work steps: refer to Figure 3 and Figure 4 When the user activates the fume extraction function of the integrated stove, the drive motor 20 is powered on and runs. Its output shaft drives the first drive gear 17 to rotate counterclockwise. The counterclockwise rotation of the first drive gear 17 drives the first driven gear 15, which meshes with it, to rotate clockwise. At the same time, the first drive gear 17 also drives the second drive gear 18 to rotate clockwise, which further drives the second driven gear 16, which meshes with the second drive gear 18, to rotate counterclockwise.

[0024] Finally, the first driven gear 15 drives the connected rotating rod 14 and the smoke guide plate 12 to rotate clockwise upwards, while the second driven gear 16 causes the smoke guide plate 12 on the other side to rotate counterclockwise upwards. The two smoke guide plates 12, like unfolded wings, rotate upwards to a predetermined tilt angle, thereby initially opening the smoke inlet channel in the central area.

[0025] When the first driven gear 15 and the second driven gear 16 rotate, they mesh with the rack 24 respectively. When the first driven gear 15 rotates clockwise, it drives the rack 24 it meshes with to move in a straight line away from the center line. When the second driven gear 16 rotates counterclockwise, it drives the rack 24 it meshes with to move in a straight line away from the center line on the other side.

[0026] Two toothed rods 24 are linked by an L-shaped rod 22, which together drive the two sliding plates 13 to move outward in sync, so that the outer smoke inlet 101, which was originally blocked by the sliding plates 13, is fully exposed. With the help of the synergistic effect of the above two sets of actions, the closed structure of the bottom surface of the range hood 10 is fully opened, forming a wide smoke inlet area enclosed by the smoke guide plate 12 and the sliding plates 13, thereby ensuring that the fumes can be efficiently captured and smoothly sucked in.

[0027] When the smoke guide plate 12 flips upward, the oil collection plate 23 fixed to its top wall tilts simultaneously. During cooking, the oil stains attached to the surface of the oil collection plate 23 are affected by gravity and flow down the inclined plate surface, eventually converging to the side near the central oil collection box 11 and dripping into the oil collection box 11, thereby realizing the automatic collection of oil stains.

[0028] After cooking is finished, when the fume extraction function is turned off, the drive motor 20 starts to rotate in the opposite direction, driving the relevant mechanism to perform completely opposite actions, and finally causing the smoke guide plate 12 and the slide plate 13 to retract to their initial positions, thereby resealing the smoke inlet 101 and restoring its hidden and flat appearance.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
