Description

Technical Field

[0001] The present application relates to the technical field of range hoods, and in particular to a range hood with a concealed smoke collection structure. Background Art

[0002] A range hood is a device that exhausts oil smoke from indoors to outdoors. It is generally composed of a smoke collecting chamber and a box body. The smoke collecting chamber of the range hood is provided with a smoke inlet connected to the smoke collecting chamber. There are many factors that affect the smoke extraction effect of the range hood, among which the smoke collection area is an important factor affecting the smoke extraction effect of the range hood. The formation of the smoke collection area plays a vital role in preventing the spread of oil smoke.

[0003] However, the existence of the smoke collecting mechanism of the conventional range hood causes the smoke collecting chamber of the range hood to occupy a large area, increases the overall size of the range hood, and seriously affects the appearance of the range hood; the hidden smoke collecting plate solves these problems. The existing hidden smoke collecting plate needs to be flipped by a driving mechanism, and the driving mechanism is usually placed under the smoke collecting plate, resulting in a large gap between the smoke collecting plate and the panel. As the range hood is used for a longer time, grease accumulates between the smoke collecting plate and the panel, affecting the service life of the driving mechanism; at the same time, there is a gap between the motion mechanism and the smoke collecting plate, affecting the overall appearance of the range hood. Summary of the Invention

[0004] The present application provides a range hood with a hidden smoke collection structure to solve the technical problem that the existing range hood places the driving mechanism under the hidden smoke collection plate, thereby affecting the service life of the driving mechanism and the overall appearance of the range hood.

[0005] The present application provides a range hood with a hidden smoke collection structure, comprising: a housing and a smoke collection chamber; the housing is connected to the smoke collection chamber, a panel, a drive mechanism and at least one smoke collection plate are provided in the smoke collection chamber, the panel is movably connected to the smoke collection chamber, the drive mechanism is fixedly connected to the panel, the smoke collection plate is foldably mounted on the panel, the smoke collection plate is located on a side of the drive mechanism and is drive-connected to the drive mechanism.

[0006] Furthermore, there are two smoke collecting plates, which are symmetrically arranged on both sides of the panel. A first rotating shaft is provided on one side of the smoke collecting plate, and a first transmission member is provided at one end of the first rotating shaft. The first rotating shaft is connected to the panel, and the first transmission member is connected to the driving mechanism.

[0007] Furthermore, the driving mechanism includes a driving member and a second rotating shaft, a second transmission member is provided in the middle of the second rotating shaft, and third transmission members are provided at both ends, the driving end of the driving member is transmission-connected to the second transmission member, and the third transmission member is transmission-connected to the first transmission member.

[0008] Furthermore, the first transmission member, the second transmission member and the third transmission member are all gear members, and the first transmission member and the third transmission member are arranged vertically.

[0009] Furthermore, when the smoke collecting plates are in an unfolded state, the panel and the smoke collecting plates on both sides thereof form a smoke collecting area.

[0010] Furthermore, the flip angle range of the smoke collecting plate is 0-90 degrees, and when the smoke collecting plate is folded, the smoke collecting plate is flush with the panel surface.

[0011] Furthermore, the range hood further comprises a controller, which is communicatively connected with the driving member to control the driving member to perform a driving action.

[0012] Furthermore, a storage box is provided on the panel, in which a lighting structure and a sensor module are integrated, and the storage box is fixedly connected to the panel.

[0014] Furthermore, a switch top plate is provided above the oil net, and a lower bottom plate is provided below the oil net. When the panel is not opened, the panel and the lower bottom plate are coplanar.

[0015] The above technical solution provided by this application has the following advantages compared with the existing technology:

[0016] This application effectively solves the problems of large structural gaps, easy accumulation of grease and inconsistent appearance of existing hidden smoke collecting plates caused by the downward placement of the driving mechanism, by placing the driving mechanism on the side of the smoke collecting plate and combining it with the installation method of the folding smoke collecting plate. Compared with the existing technology, the side placement of the driving mechanism avoids the direct contact area between the mechanism and the bottom of the smoke collecting plate in the traditional layout, greatly reduces the assembly gap between the panel and the smoke collecting plate, and reduces the risk of grease infiltrating into the interior of the driving mechanism through physical space isolation, thereby improving the sealing and service life; at the same time, the folding smoke collecting plate forms a compact fitting structure with the panel when stored, which not only reduces the overall footprint of the smoke collecting chamber to optimize the appearance, but also expands the coverage of the smoke collecting area when unfolded through dynamic folding action, thereby improving the smoke collecting efficiency.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0028] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations.

[0029] In order to solve the technical problem that the existing range hood places the driving mechanism 4 under the hidden smoke collecting plate 5, thereby affecting the service life of the driving mechanism 4 and the overall appearance of the range hood, the present application provides a range hood with a hidden smoke collecting structure, which effectively solves the problems of large structural gaps, easy accumulation of grease and inconsistent appearance of the existing hidden smoke collecting plate 5 caused by the downward placement of the driving mechanism 4.

[0030] See also Figures 1 to 4 The embodiment of the present application provides a range hood with a hidden smoke collection structure, comprising: a box body 2 and a smoke collection chamber 1; the box body 2 is connected to the smoke collection chamber 1, and a panel 3, a driving mechanism 4 and at least one smoke collection plate 5 are provided in the smoke collection chamber 1, the panel 3 is movably connected to the smoke collection chamber 1, the driving mechanism 4 is fixedly connected to the panel 3, the smoke collection plate 5 is foldably mounted on the panel 3, the smoke collection plate 5 is located on the side of the driving mechanism 4 and is drivingly connected to the driving mechanism 4.

[0031] Specifically, the smoke collection chamber 1 and the panel 3 are movably connected via a rotating shaft to enable opening and closing. A drive device is installed in the smoke collection chamber 1, which is connected to the rotating shaft to drive the panel 3 to rotate about the rotating shaft. A foldable smoke collecting plate 5 is mounted on the panel 3 and located to the side of the drive mechanism 4. When the range hood is turned on, the panel 3 is opened by the drive device. At this time, the user can choose whether to open the smoke collecting plate 5 based on the level of oil smoke production. When the user needs to open the smoke collecting plate 5, the drive mechanism 4 is activated, causing the smoke collecting plate 5 to unfold, forming a three-dimensional smoke collecting area 6. When the range hood is closed, the drive mechanism 4 drives in the opposite direction, allowing the smoke collecting plate 5 to be folded and stored inside the panel 3. The lateral arrangement of the drive mechanism 4 prevents any gap between the smoke collecting plate 5 and the panel 3. The side layout of the driving mechanism 4 and the foldable design of the smoke collecting plate 5 make the overall structure of the range hood more compact; at the same time, the separation of the driving mechanism 4 and the smoke collecting plate 5 reduces the possibility of grease seeping into the interior of the mechanism from the joint between the panel 3 and the smoke collecting plate 5, which not only improves the sealing protection capability of the moving parts, but also avoids jamming or wear problems caused by grease accumulation.

[0032] like Figure 1-3 As shown, there are two smoke collecting plates 5, which are symmetrically arranged on both sides of the panel 3. A first rotating shaft 51 is provided on one side of the smoke collecting plate 5, and a first transmission member 52 is provided at one end of the first rotating shaft 51. The first rotating shaft 51 is connected to the panel 3, and the first transmission member 52 is connected to the driving mechanism 4.

[0033] Specifically, two cigarette collecting plates 5 are symmetrically arranged on both sides of the panel 3. Each cigarette collecting plate 5 is movably connected to the panel 3 through a first rotating shaft 51 on one side close to the panel 3. A first transmission member 52 extends from one end of the first rotating shaft 51 and forms a transmission connection with the driving mechanism 4. When the driving mechanism 4 is running, power is transmitted to the first rotating shaft 51 through the first transmission member 52, driving the cigarette collecting plates 5 on both sides to synchronously unfold or fold around the rotating shaft. The symmetrically distributed cigarette collecting plates 5 achieve bilateral synchronous movement through independent rotating shafts and transmission members, ensuring that the left and right forces of the cigarette collecting area 6 are balanced when the cigarette collecting area 6 is unfolded, avoiding mechanical jamming or structural deformation caused by unilateral drive; at the same time, the fixed connection between the first rotating shaft 51 and the panel 3 enhances the stability of the rotating fulcrum of the cigarette collecting plate 5 and reduces vibration and noise during operation.

[0034] It is understandable that, in this embodiment, the number of the smoke collecting plates 5 is two, and in other embodiments, the number may be more than two, and the specific setting is based on actual conditions, which is not limited here.

[0035] like Figure 1-2 As shown, the smoke collecting plate 5 is a fan-shaped structure, wherein one straight edge is fixedly connected to the first rotating shaft 51, and the other straight edge abuts against the smoke collecting chamber 1 when the smoke collecting plate 5 is in the expanded state, and the arc edge provides a certain angle (fan-shaped angle) between the panel 3 in the expanded state and the smoke collecting chamber 1.

[0036] Specifically, through the geometric characteristics of the fan-shaped structure, the smoke collecting plate 5 uses the arc edge as the guiding boundary when it is unfolded, and utilizes the fan-shaped angle to naturally form an outward-expanding smoke collecting curved surface, thereby enhancing the ability to wrap and guide the smoke; at the same time, the abutment design of the straight edge and the smoke collecting chamber 1 forms a stable mechanical support point in the unfolded state, thereby preventing the smoke collecting plate 5 from shaking due to the impact of airflow, and the close contact between the abutment edge and the smoke collecting chamber 1 can reduce the leakage of smoke from the joints.

[0037] like Figure 2-3 As shown, the driving mechanism 4 includes a driving member 41 and a second rotating shaft 42. A second transmission member 43 is provided in the middle of the second rotating shaft 42, and a third transmission member 44 is provided at both ends. The driving end of the driving member 41 is transmission-connected to the second transmission member 43, and the third transmission member 44 is transmission-connected to the first transmission member 52.

[0038] Specifically, the drive mechanism 4 outputs power through a drive member 41, the drive end of which is connected to a second transmission member 43 in the middle of the second rotating shaft 42, driving the second rotating shaft 42 to rotate. Third transmission members 44 at either end of the second rotating shaft 42 engage or interact with the first transmission members 52 on either side. When the drive member 41 is activated, power is transmitted to the second rotating shaft 42 via the second transmission member 43. The third transmission member 44 then synchronously drives the first transmission members 52 on either side, ultimately causing the cigarette collecting plates 5 on both sides to unfold or fold around the first rotating shaft 51. This centralized drive in the middle of the second rotating shaft 42 and the symmetrically distributed third transmission members 44 at both ends achieve synchronized motion control of the cigarette collecting plates 5 on both sides, eliminating mechanical delays or uneven force caused by unilateral drive.

[0039] It can be understood that the driving member 41 in this embodiment is a motor. In other embodiments, the driving member 41 can also be a pneumatic mechanism, a hydraulic mechanism, an electromagnetic linear driving mechanism 4, etc., which can be specifically set according to actual conditions and is not limited here.

[0040] like Figure 2-4 As shown, the first transmission member 52 , the second transmission member 43 and the third transmission member 44 are all gear members, and the first transmission member 52 and the third transmission member 44 are vertically arranged.

[0041] Specifically, in this embodiment, the first transmission member 52, the second transmission member 43, and the third transmission member 44 are all gears. The second transmission member 43 is fixed to the middle of the second rotating shaft 42 and meshes with the drive end gear of the driving member 41. The third transmission members 44 at both ends of the second rotating shaft 42 mesh perpendicularly with the first transmission members 52 on either side. When the driving member 41 is in operation, power is transmitted to the second rotating shaft 42 through the gear of the second transmission member 43, driving the gear of the third transmission member 44 to rotate, which in turn drives the gear of the first transmission member 52 meshing perpendicularly therewith, ultimately controlling the expansion or folding of the cigarette collecting plate 5 via the first rotating shaft 51. The vertical meshing design of the gears realizes the conversion of the power transmission direction from axial (second rotating shaft 42) to radial (first rotating shaft 51), so that the driving mechanism 4 can efficiently complete the steering requirements of the transmission path in a limited space; at the same time, the precise transmission characteristics of the gear meshing ensure that the power transmission between the first transmission member 52 and the third transmission member 44 is slip-free and delay-free, thereby ensuring the synchronization and angular consistency of the unfolding / folding actions of the bilateral cigarette collecting plates 5; in addition, the structural self-locking characteristics of the vertically meshing gear group can prevent the cigarette collecting plates 5 from being displaced due to external force or airflow impact in the non-driven state, thereby enhancing the position stability of the cigarette collecting plates 5 after unfolding.

[0042] Furthermore, the driving member 41 rotates in the opposite direction after receiving the closing signal, and the power is transmitted to the second rotating shaft 42 through the gear of the second transmission member 43, driving the second rotating shaft 42 to rotate in the axial direction opposite to the unfolding direction. The gears of the third transmission members 44 at both ends of the second rotating shaft 42 rotate in the opposite direction with the shaft, and drive the gears of the first transmission members 52 on both sides to rotate in the opposite direction around the first rotating shaft 51 through a vertical meshing relationship. The rotation of the first rotating shaft 51 drives the fan-shaped smoke collecting plate 5 to fold inward with the fixed rotating shaft as the fulcrum, and its other straight edge is separated from the abutment state with the smoke collecting chamber 1, and the arc edge is gathered along the inner contour of the panel 3 to form a compact folded shape. During the folding process of the smoke collecting plate 5, the panel 3 closes inward along the movement trajectory of the driving mechanism 4, and the folded smoke collecting plate 5 is completely wrapped in the hidden space between the panel 3 and the smoke collecting chamber 1, ensuring that there are no protrusions or gaps on the outside. The self-locking property of the gear meshing structure keeps the smoke collecting plate 5 fixed after being stored in place, avoiding accidental unfolding due to gravity or vibration. At the same time, after the panel 3 is closed, it fits tightly with the smoke collecting chamber 1 to prevent oil smoke from penetrating into the internal transmission structure.

[0043] like Figure 1 As shown, when the smoke collecting plates 5 are in the unfolded state, the panel 3 and the smoke collecting plates 5 on both sides thereof form a smoke collecting area 6 .

[0044] Specifically, when the smoke collecting plates 5 are fully deployed, the panel 3 extends outward through the symmetrically distributed smoke collecting plates 5 on both sides, forming a three-sided enclosed smoke collecting area 6. The panel 3 serves as the top boundary of the smoke collecting area 6, and the smoke collecting plates 5 on both sides serve as the left and right boundaries, respectively. Together, the three form a semi-enclosed diversion space that directly covers the oil smoke diffusion path above the stove. Through the coordinated deployment of the panel 3 and the smoke collecting plates 5 on both sides, a three-dimensional and continuous smoke collecting curved surface is formed, significantly expanding the lateral interception range of oil smoke. In particular, for oil smoke that escapes to the sides during cooking, it can be quickly guided to converge at the center of the smoke collecting chamber 1, improving the efficiency of oil smoke extraction.

[0045] In some optional embodiments, the flip angle range of the cigarette collecting plate 5 is 0-90°. When the cigarette collecting plate 5 is folded, the cigarette collecting plate 5 is flush with the surface of the panel 3 .

[0046] Specifically, the flip angle range of the smoke collecting plate 5 is 0° (fully folded) to 90° (fully unfolded). When folded to 0°, the surface of the smoke collecting plate 5 is completely flush with the outer surface of the panel 3, without any protrusions or misalignment. By limiting the maximum unfolding angle of the smoke collecting plate 5 to 90°, it is ensured that it forms a vertical downward smoke collecting guide surface in the unfolded state, directly covering the rising path of oil smoke and improving the efficiency of intercepting oil smoke. At the same time, the flush design when folded at 0° allows the smoke collecting plate 5 and the panel 3 to form a seamless overall plane after closing, eliminating the surface bumps or gaps caused by angle deviation in traditional flip structures, maintaining a simple appearance of the range hood and preventing grease accumulation in the gaps.

[0047] In some optional embodiments, the range hood further includes a controller, which is communicatively connected to the driving member 41 to control the driving member 41 to perform a driving action.

[0048] Specifically, the range hood establishes a communication connection with the driver 41 through a controller (such as a microprocessor or a PLC module). After receiving user instructions or sensor feedback signals, the controller sends a control instruction to the driver 41, and the driver 41 executes the action of unfolding, folding or adjusting the angle of the smoke collecting plate 5 accordingly. Through the integration of the controller, the intelligent control of the drive mechanism 4 can be realized. The user can operate the movement state of the smoke collecting plate 5 with one click through a button, touch screen or remote terminal (such as a mobile phone APP), simplifying the use process and improving the convenience of interaction. At the same time, the controller dynamically adjusts the operating parameters of the driver 41 (such as the start-stop sequence and the steering speed) according to the real-time working conditions (such as the oil smoke concentration and the fan speed), so that the unfolding angle of the smoke collecting plate 5 is accurately matched with the smoking demand, avoiding energy waste caused by mechanical redundant actions. In addition, the fault detection module built into the controller can monitor the operating status of the driver 41 (such as overload and jamming) in real time and trigger protection mechanisms (such as power off and reverse reset), significantly improving the safety and service life of the mechanism.

[0049] like Figure 1-2As shown, a storage box 7 is further provided on the panel 3 , in which a lighting structure and a sensor module are integrated. The storage box 7 is fixedly connected to the panel 3 .

[0050] Specifically, a storage box 7 with an integrated lighting structure and a sensor module is fixedly mounted on the panel 3, wherein the lighting structure (such as an LED light strip) is embedded in the edge or interior of the storage box 7 to provide local lighting or ambient light source; the sensor module (such as an infrared sensor, a smoke detection unit) is integrated into the surface or interior of the storage box 7 shell to sense environmental parameters or user operation signals in real time.

[0051] like Figure 1 and Figure 4 As shown, the smoke collecting chamber 1 is further provided with an oil net 11 and a smoke inlet 12 . The oil net 11 is installed at the smoke inlet 12 , which is communicated with the box body 2 . The oil net 11 is provided with a plurality of through holes 111 , which are communicated with the smoke inlet 12 .

[0052] Specifically, an oil net 11 is installed at the smoke inlet 12 of the smoke collecting chamber 1. A number of through holes 111 are evenly distributed on the surface of the oil net 11, and the through holes 111 are directly connected to the smoke inlet 12. The oil net 11 is integrated with the panel 3 through a detachable or fixed connection. When the oil smoke enters the smoke collecting chamber 1, it is first filtered through the through holes 111 of the oil net 11 to intercept large particles of oil and prevent them from entering the interior of the box 2; the filtered oil smoke enters the smoke inlet 12 through the through holes 111, and is then directed to the fan system inside the box 2 for discharge. The uniform distribution of the through holes 111 in the present application optimizes the airflow distribution of the smoke inlet 12, avoids noise or suction attenuation problems caused by excessive local airflow, and improves smoking efficiency.

[0053] like Figure 1 As shown, a switch top plate 8 is provided above the oil net 11 and a lower bottom plate 9 is provided below the oil net 11. When the panel 3 is not opened, the panel 3 and the lower bottom plate 9 are coplanar.

[0054] Specifically, a switch adjustment button (e.g., a physical key or touch sensor) is provided on the outer surface of the switch top plate 8. This button is connected to the controller via an electrical signal. A user presses or touches the button to trigger a signal. The controller, upon receiving the signal, controls the drive mechanism 4 to open and close the panel 3, adjust its angle, and turn the range hood on and off, and adjust its air speed. The range hood operates by opening the panel 3 to expose the oil screen 11. When the panel 3 is closed, it resets and aligns with the lower base plate 9.

[0055] Furthermore, the panel 3, the switch top plate 8 and the lower bottom plate 9 in this embodiment are all made of glass. In other embodiments, they can also be made of metal or plastic, depending on the actual situation.
