[0001] The present application relates to the technical field of range hood, and particularly relates to a range hood with hidden smoke gathering structure and a range hood method. BACKGROUND

[0002] The range hood is a device for discharging oil fume from indoor to outdoor, which is generally composed of a smoke collecting cavity and a fan system. The smoke collecting cavity of the range hood is provided with a smoke inlet connected with the smoke collecting cavity. There are many factors affecting the smoke suction effect of the range hood, and the smoke gathering area is an important factor affecting the smoke suction effect of the range hood. The formation of the smoke gathering area plays a crucial role in preventing the spread of oil fume.

[0017] Optionally, in step S42, when the controller receives the first feedback signal, the controller controls the driving mechanism to flip out the smoke-collecting side panel; when the controller receives the second feedback signal, the controller controls the driving mechanism to flip out the smoke-collecting side panel or controls the fan system to increase the oil fume suction gear to the highest gear while the smoke-collecting side panel has been flipped out.

[0018] Optionally, in step S42, the driving mechanism is fixedly arranged on one side of the smoke collecting panel close to the smoke collecting chamber and is rotatably connected to the smoke collecting side panels on both sides of the smoke collecting panel.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments.

[0038] See also Figures 1 to 4The oil extractor hood with the hidden smoke gathering structure provided by the embodiment of the application comprises: a fan system 2 and a smoke collecting cavity 1; the fan system 2 is connected with the smoke collecting cavity 1; the smoke collecting cavity 1 is internally provided with a smoke gathering panel 3, a driving mechanism 4 and at least one smoke gathering side plate 5; the smoke gathering panel 3 is movably connected with the smoke collecting cavity 1; the driving mechanism 4 is fixedly connected with the smoke gathering panel 3; the smoke gathering side plate 5 is foldably arranged on one side or both sides of the smoke gathering panel 3; and the smoke gathering side plate 5 is located on one side or both sides of the driving mechanism 4 and is drivingly connected with the driving mechanism 4.

[0039] Specifically, the smoke collecting cavity 1 and the smoke gathering panel 3 are movably connected through a rotating shaft to realize opening and closing; the smoke collecting cavity 1 is internally provided with a driving device; the driving device is connected with the rotating shaft to drive the smoke gathering panel 3 to rotate around the rotating shaft; the foldable smoke gathering side plate 5 is mounted on the smoke gathering panel 3 and is located on one side or both sides of the driving mechanism 4. When the oil extractor hood is started, the smoke gathering panel 3 is opened under the driving action of the driving device; at this time, the user can select whether to open the smoke gathering side plate 5 according to the generation degree of the oil fume; when the user needs to open the smoke gathering side plate 5, the driving mechanism 4 is started to drive the smoke gathering side plate 5 to unfold, thereby forming a three-dimensional smoke gathering area 6; when the oil extractor hood is closed, the driving mechanism 4 is reversely driven to enable the smoke gathering side plate 5 to be foldably stored inside the smoke gathering panel 3; the driving mechanism 4 is fixedly arranged close to the inside of the smoke collecting cavity 1, which can avoid the existence of a gap between the smoke gathering side plate 5 and the smoke gathering panel 3. Through the inside surface layout of the driving mechanism 4 and the foldable structure design of the smoke gathering side plate 5, the overall structure of the oil extractor hood is more compact; at the same time, the position separation of the driving mechanism 4 and the smoke gathering side plate 5 reduces the possibility of the oil penetrating into the inside of the mechanism from the joint between the smoke gathering panel 3 and the smoke gathering side plate 5, which not only improves the sealing protection capability of the moving parts, but also avoids the problems of jamming or wear caused by the accumulation of oil.

[0040] As shown in Figures 1-3 the number of the smoke gathering side plates 5 is two, and the smoke gathering side plates 5 are symmetrically arranged on both sides of the smoke gathering panel 3; one side of the smoke gathering side plate 5 is provided with a first rotating shaft 51; one end of the first rotating shaft 51 is provided with a first transmission member 52; the first rotating shaft 51 is connected with the smoke gathering panel 3 and can rotate relative to the smoke gathering panel 3; and the first transmission member 52 is drivingly connected with the driving mechanism 4.

[0041] Specifically, two smoke gathering side plates 5 are symmetrically arranged on both sides of the smoke gathering panel 3, and each smoke gathering side plate 5 is fixedly connected to the first rotating shaft 51 near one side of the smoke gathering panel 3. One end of the first rotating shaft 51 extends out of the first transmission member 52 and is in transmission connection with the driving mechanism 4. When the driving mechanism 4 operates, power is transmitted to the first rotating shaft 51 through the first transmission member 52, driving the two smoke gathering side plates 5 to synchronously expand or fold around the rotating shaft. The symmetrically distributed smoke gathering side plates 5 realize bilateral synchronous movement through independent rotating shafts and transmission members, ensuring that the smoke gathering area 6 is balanced in left and right forces when it is expanded, avoiding mechanical jamming or structural deformation caused by unilateral driving. At the same time, the fixed connection of the first rotating shaft 51 and the smoke gathering panel 3 enhances the stability of the rotating fulcrum of the smoke gathering side plate 5, reducing vibration and noise during operation.

[0042] It can be understood that the number of smoke gathering side plates 5 in the embodiment is two, and in other embodiments, it can be more than two, which is specifically set according to actual conditions, which is not limited here.

[0043] As shown in Figures 1-2 , the smoke gathering side plate 5 is a fan-shaped structure, one of whose straight edges is fixedly connected to the first rotating shaft 51, and the other straight edge is in abutment with the smoke collecting cavity 1 when the smoke gathering side plate 5 is in an expanded state. The arc edge provides a certain angle (fan angle) between the smoke gathering panel 3 in the expanded state and the smoke collecting cavity 1.

[0044] Specifically, through the geometric characteristics of the fan-shaped structure, the smoke gathering side plate 5 expands with the arc edge as the guide boundary, and the fan angle naturally forms an outwardly expanding smoke gathering curved surface, enhancing the wrapping and flow guiding capacity of the oil fume. At the same time, the abutment design of the straight edge and the smoke collecting cavity 1 forms a stable mechanical support point in the expanded state, avoiding the shaking of the smoke gathering side plate 5 due to air flow impact, and the close contact of the abutment edge with the smoke collecting cavity 1 can reduce the leakage of oil fume from the joint.

[0045] As shown in Figures 2-3 , the driving mechanism 4 includes a driving member 41 and a second rotating shaft 42. The second rotating shaft 42 is provided with a second transmission member 43 in the middle and a third transmission member 44 at each end. The driving end of the driving member 41 is in transmission connection with the second transmission member 43, and the third transmission member 44 is in transmission connection with the first transmission member 52.

[0046] Specifically, the driving mechanism 4 outputs power through the driving member 41, the driving end is connected with the second transmission member 43 in the middle of the second rotating shaft 42, and drives the second rotating shaft 42 to rotate; the third transmission members 44 at both ends of the second rotating shaft 42 are respectively engaged with or linked with the first transmission members 52 on both sides. When the driving member 41 is started, the power is transmitted to the second rotating shaft 42 through the second transmission member 43, and then the first transmission members 52 on both sides are synchronously driven by the third transmission members 44, and finally the two sides of the smoke gathering side plate 5 are driven to unfold or fold around the first rotating shaft 51. Through the centralized driving of the middle of the second rotating shaft 42 and the symmetrical distribution of the third transmission members 44 at both ends, the synchronous motion control of the double-sided smoke gathering side plate 5 is realized, so that the mechanical delay or uneven force caused by unilateral driving is eliminated.

[0047] It can be understood that the driving member 41 in the embodiment is a motor, and 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 set according to actual conditions, and is not limited here.

[0048] As shown in Figures 2-4 , 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.

[0049] Specifically, the first transmission member 52, the second transmission member 43 and the third transmission member 44 in the embodiment are all gears, wherein the second transmission member 43 is fixed to the middle of the second rotating shaft 42 and is engaged with the driving end gear of the driving member 41, and the third transmission members 44 at both ends of the second rotating shaft 42 are respectively vertically engaged with the first transmission members 52 on both sides. When the driving member 41 operates, the power is transmitted to the second rotating shaft 42 through the second transmission member 43 gear, drives the third transmission member 44 gear to rotate, and then drives the first transmission member 52 gear vertically engaged therewith to rotate, and finally controls the smoke gathering side plate 5 to unfold or fold through the first rotating shaft 51. The vertical engagement design of the gears realizes the conversion of the power transmission direction from the axial direction (second rotating shaft 42) to the radial direction (first rotating shaft 51), so that the driving mechanism 4 can efficiently complete the turning requirement of the transmission path in a limited space; at the same time, the precise transmission characteristics of the gear engagement ensure that the power transmission between the first transmission member 52 and the third transmission member 44 is without slip and delay, and the synchronization and angle consistency of the unfolding / folding action of the double-sided smoke gathering side plate 5 are guaranteed; in addition, the structure self-locking characteristics of the vertically engaged gear set can prevent the smoke gathering side plate 5 from being displaced due to external force or airflow impact in the non-driving state, and enhance the position stability of the unfolded smoke gathering side plate 5.

[0050] Further, the driving member 41 reversely rotates 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 third transmission member 44 gears at both ends of the second rotating shaft 42 reversely rotate with the shaft, and drive the first transmission member 52 gears on both sides to reversely rotate around the first rotating shaft 51 through the vertical engagement relationship. The rotation of the first rotating shaft 51 drives the fan-shaped fume folding side plate 5 to fold inward with the fixed rotating shaft as the fulcrum, and the other straight edge is separated from the abutting state with the fume collecting cavity 1. The arc edge is folded along the inner contour of the fume folding panel 3 to form a compact folded shape. During the folding process of the fume folding side plate 5, the fume folding panel 3 closes inward along the movement track of the driving mechanism 4, completely wrapping the folded fume folding side plate 5 in the hidden space between the fume folding panel 3 and the fume collecting cavity 1, ensuring that there is no protrusion or gap outside. The self-locking property of the gear engagement structure keeps the fume folding side plate 5 fixed after being stored in place, avoiding accidental unfolding due to gravity or vibration. At the same time, the fume folding panel 3 closely fits the fume collecting cavity 1 after closing, preventing oil fumes from penetrating into the internal transmission structure.

[0051] As shown in Figure 1 When the fume folding side plate 5 is in the unfolded state, the fume folding panel 3 and the fume folding side plates 5 on both sides form a fume folding area 6.

[0052] Specifically, when the fume folding side plate 5 is completely unfolded, the fume folding panel 3 extends outward through the symmetrically distributed fume folding side plates 5 on both sides, forming a fume folding area 6 with a three-sided enclosure structure. The fume folding panel 3 serves as the top side boundary of the fume folding area 6, and the fume folding side plates 5 on both sides serve as the left and right side boundaries, respectively. Together, they form a semi-closed flow guiding space that directly covers the oil fume diffusion path above the cooking appliance. Through the coordinated unfolding of the fume folding panel 3 and the fume folding side plates 5 on both sides, a three-dimensional and continuous fume folding surface is formed, significantly expanding the horizontal interception range of oil fumes. Especially for oil fumes that escape to both sides during cooking, it can quickly guide them to converge towards the center of the fume collecting cavity 1, improving the oil fume suction efficiency.

[0053] In some optional embodiments, the fume folding side plate 5 has a flip angle range of 0-90°, and when the fume folding side plate 5 is folded, the fume folding side plate 5 is flush with the surface of the fume folding panel 3.

[0054] Specifically, the turning angle range of the smoke collection side plate 5 is 0° (fully folded) to 90° (fully unfolded), when folded to 0°, the surface of the smoke collection side plate 5 is completely flush with the outer surface of the smoke collection panel 3, without protrusion or misalignment. By limiting the maximum unfolding angle of the smoke collection side plate 5 to 90°, it is ensured that it forms a vertically downward smoke collection guide surface in the unfolded state, directly covering the oil fume rising path, improving the interception efficiency of oil fume; at the same time, the flush design at 0° folding makes the smoke collection side plate 5 and the smoke collection panel 3 form a seamless integrated whole plane after closing, eliminating the surface concave-convex or gap caused by angle deviation of the traditional turning structure, both maintaining the simple appearance of the range hood and avoiding grease accumulation in the gap.

[0055] In some optional embodiments, the range hood further comprises a controller, which is in communication connection with the driving member 41 to control the driving member 41 to perform the driving action.

[0056] Specifically, the range hood establishes communication connection with the driving member 41 through a controller (such as a microprocessor or a PLC module), and the controller sends a control instruction to the driving member 41 after receiving a user instruction or a sensor feedback signal, and the driving member 41 performs the unfolding, folding or angle adjusting action of the smoke collection side plate 5 accordingly. Through the integration of the controller, intelligent control of the driving mechanism 4 can be realized, and the user can operate the movement state of the smoke collection side plate 5 through a key, a touch screen or a remote terminal (such as a mobile phone APP), simplifying the use process and improving the interactive convenience; at the same time, the controller dynamically adjusts the operating parameters (such as start-stop timing and turning speed) of the driving member 41 according to the real-time working condition (such as oil fume concentration and fan speed), so that the unfolding angle of the smoke collection side plate 5 is accurately matched with the smoke collection demand, avoiding energy waste caused by mechanical redundant action; in addition, the fault detection module built in the controller can monitor the operating state (such as overload and jam) of the driving member 41 in real time, and trigger the protection mechanism (such as power-off and reverse reset), significantly improving the operating safety and service life of the mechanism.

[0057] As shown in Figures 1-2 , the smoke collection panel 3 is also provided with a storage box 7, and the light structure and the sensor module are integrally arranged in the storage box 7, and the storage box 7 is fixedly connected to the smoke collection panel 3.

[0058] Specifically, the smoke collection panel 3 is fixedly installed with the storage box 7 which integrates the light structure and the sensor module, wherein the light structure (such as LED light strip) is embedded in the edge or inside of the storage box 7, for providing local lighting or atmosphere light source; the sensor module (such as infrared sensor) is integrated on the surface or inside of the storage box 7 shell, for real-time sensing of environmental parameters.

[0059] As shown in Figure 1 and Figure 4As shown, the smoke collecting cavity 1 is also provided with an oil screen 11 and a smoke inlet 12, the oil screen 11 is installed on the smoke inlet 12, the smoke inlet 12 is communicated with the fan system 2, and the oil screen 11 is provided with a plurality of through holes 111 communicated with the smoke inlet 12.

[0060] Specifically, the oil screen 11 is installed at the smoke inlet 12 of the smoke collecting cavity 1, the surface of the oil screen 11 is uniformly distributed with a plurality of through holes 111, and the through holes 111 are directly communicated with the smoke inlet 12. The oil screen 11 is integrated with the smoke panel 3 by a detachable or fixed connection mode. When the oil fume enters the smoke collecting cavity 1, it is first filtered by the through holes 111 of the oil screen 11, intercepting large particles of oil and preventing them from entering the inside of the fan system 2. The filtered oil fume enters the smoke inlet 12 through the through holes 111, and then is discharged into the fan system inside the fan system. The uniform distribution of the through holes 111 optimizes the airflow distribution of the smoke inlet 12, avoids the problem of noise or suction decay caused by too fast local airflow, and improves the smoke suction efficiency.

[0061] As shown in Figure 1 , the upper side of the oil screen 11 is provided with an opening and closing top plate 8, and the lower side is provided with a lower bottom plate 9. When the smoke panel 3 is not opened, the smoke panel 3 is coplanar with the lower bottom plate 9.

[0062] Specifically, the outer surface of the opening and closing top plate 8 is provided with an opening and closing adjusting button (such as a physical button or a touch sensor), and the button is connected with the controller through an electrical signal. The user triggers the signal by pressing or touching the button, and the controller controls the driving mechanism 4 to execute the opening, closing, angle adjustment of the smoke panel 3, and the opening and closing, wind speed adjustment of the range hood. The range hood exposes the oil screen 11 by opening the smoke panel 3, and the smoke panel 3 is reset and aligned with the lower bottom plate 9 when the smoke panel 3 is closed.

[0063] Further, the smoke panel 3, the opening and closing top plate 8 and the lower bottom plate 9 in the embodiment are all of glass material, and in other embodiments, they can also be of metal or plastic material, which is specifically set according to actual conditions.

[0064] Please refer to Figure 5 , the application also provides a method for sucking oil fume by the range hood with the hidden smoke collecting structure, which adopts the range hood with the hidden smoke collecting structure as described above, and includes the following steps:

[0065] Step S1: turn on the power supply;

[0066] Step S2: adjust the fan system oil fume suction gear, rotate the smoke panel, and work the fan system;

[0067] Step S3: the sensor module detects the temperature below in real time;

[0068] Step S4: when the detected temperature is higher than the preset temperature, the smoke panel is turned over.

[0069] Step S5: disconnect the power supply, and the range hood with the hidden smoke structure ends the smoke absorption operation.

[0070] Specifically, in step S2, the smoke absorption gear of the fan system 2 can be automatically set to a fixed gear after being turned on, or adjusted by the user, so that the fan system 2 is in a working gear at the initial work to perform the smoke absorption operation; it can be understood that the smoke panel 3 can be driven by the driving device to a fixed position when it is turned on to work, so as to facilitate the entry of the oil smoke below and the smooth turning of the smoke side plate 5, or the smoke panel 3 is manually turned to a fixed position by the user.

[0071] In step S3, the sensor module is arranged on one side of the smoke panel 3 close to the smoke collecting cavity 1, and the sensor module detects the temperature below when it is rotated out of the smoke collecting cavity 1 at one end of the smoke panel 3. The hidden setting of the sensor module is realized, which is completely wrapped in the hidden space between the smoke panel 3 and the smoke collecting cavity 1, without protrusions or gaps due to external setting, which is beneficial to the design of product ultra-fine and integration.

[0072] Further, step S4 includes the following steps:

[0073] Step S41: when the sensor module detects that the temperature is higher than the preset temperature, the sensor module sends a feedback signal to the controller;

[0074] Step S42: when the controller receives the feedback signal, the controller controls the driving mechanism to turn the smoke side plates on both sides of the smoke panel out, so that the smoke panel and the smoke side plates form a three-dimensional smoke collection area.

[0075] When the actual temperature is higher than the preset temperature, it indicates that the pot at the lower position is in the working state, such as cooking or frying. As the temperature rises, the amount of oil smoke increases, which can easily cause part of the oil smoke near the smoke panel 3 to escape from the side without being absorbed in time, causing pollution to the indoor environment. By controlling the smoke side plate 5 to turn out when the amount of oil smoke increases, the smoke panel 3 and the smoke side plate 5 form a three-dimensional smoke collection area, which significantly enhances the horizontal interception effect of the oil smoke, so that the originally horizontally dispersed oil smoke can quickly converge to the center of the smoke collecting cavity 1, which is beneficial to improve the oil smoke absorption efficiency.

[0076] In step S41, the sensor module sends a first feedback signal to the controller when it detects that the temperature is higher than a first preset temperature, and sends a second feedback signal to the controller when it detects that the temperature is higher than a second preset temperature, wherein the first temperature is greater than the second temperature.

[0077] In step S42, the controller controls the driving mechanism 4 to turn the smoke gathering side plate 5 out upon receiving the first feedback signal; the controller controls the driving mechanism to turn the smoke gathering side plate 5 out or controls the fan system 2 to increase the oil fume suction level to the highest level while the smoke gathering side plate 5 has been turned out upon receiving the second feedback signal.

[0078] It can be understood that the preset temperature in the sensor module includes a first temperature and a second temperature greater than the first temperature, when the sensor module detects that the temperature is greater than the first temperature but not greater than the second temperature, the controller controls the smoke gathering side plate 5 to turn out to quickly gather the increased oil fume to the center of the smoke collecting cavity, and improve the oil fume suction efficiency; when the sensor module detects that the temperature is greater than the second temperature, there will be more oil fume than when the temperature is the first temperature, while ensuring that the smoke gathering side plate 5 is turned out, the fan system 2 is adjusted to the highest level of oil fume suction, reducing the probability of oil fume escaping, and increasing the suction efficiency when there is more oil fume. Preferably, the first temperature is 100-150℃, and the second temperature is 150-200℃.

[0079] Further, in step S42, the driving mechanism 4 is fixedly arranged on one side of the smoke gathering panel 3 close to the smoke collecting cavity 1 and is rotatably connected with the smoke gathering side plate 5 on both sides of the smoke gathering panel 3, the driving mechanism 4 is controlled to rotate the smoke gathering side plate 5 away from the center of the smoke gathering panel 3 to form a three-dimensional smoke gathering area with the smoke gathering panel 3, or to rotate the smoke gathering side plate 5 towards the center of the smoke gathering panel 3 to be attached to the smoke gathering panel 3. Specifically, the driving mechanism 4 outputs power through the driving part 41, the driving end of which is connected with the second transmission part 43 in the middle of the second rotating shaft 42 to drive the second rotating shaft 42 to rotate, the third transmission part 44 connected with the first transmission part 52 at both ends of the second rotating shaft 42 is engaged or linked with the first transmission part 52, the first transmission part 52 drives the first rotating shaft 51 to rotate, and the first rotating shaft 51 drives the smoke gathering side plate 5 connected therewith to rotate.

[0080] 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 is vertically arranged between the third transmission member 44. The second transmission member 43 is fixed to the middle part of the second rotating shaft 42 and is engaged with the driving end gear of the driving member 41, and the third transmission member 44 at both ends of the second rotating shaft 42 is vertically engaged with the first transmission member 52 on both sides. When the driving member 41 operates, the power is transmitted to the second rotating shaft 42 through the second transmission member 43 gear, drives the third transmission member 44 gear to rotate, and then drives the first transmission member 52 gear vertically engaged therewith to rotate, and finally controls the unfolding or folding of the smoke gathering side plate 5 through the first rotating shaft 51. The vertical engagement design of the gear realizes the conversion of the power transmission direction from the axial direction (the second rotating shaft 42) to the radial direction (the first rotating shaft 51), so that the driving mechanism 4 can efficiently complete the steering requirement of the transmission path in a limited space; at the same time, the precise transmission characteristics of the gear engagement ensure that there is no slip and no delay in the power transmission between the first transmission member 52 and the third transmission member 44, and the synchronization and angle consistency of the unfolding / folding action of the double-sided smoke gathering side plate 5 are guaranteed; in addition, the self-locking characteristic of the vertical engagement gear set can prevent the smoke gathering side plate 5 from being displaced due to external force or airflow impact in the non-driving state, and enhance the position stability of the unfolded smoke gathering side plate 5. Through the centralized driving of the middle part of the second rotating shaft 42 and the symmetrical distribution of the third transmission member 44 at both ends, the synchronous motion control of the double-sided smoke gathering side plate 5 is realized, so that the mechanical delay or uneven force caused by unilateral driving is eliminated.

[0081] The driving mechanism 4 is arranged on the side of the smoke gathering panel 3 close to the smoke collecting cavity 1, so as to avoid the gap between the smoke gathering side plate 5 and the smoke gathering panel 3; during the folding process of the smoke gathering side plate 5, the smoke gathering panel 3 closes inward along the movement track of the driving mechanism 4, completely wrapping the folded smoke gathering side plate 5 in the hidden space between the smoke gathering panel 3 and the smoke collecting cavity 1, and ensuring that there is no protrusion or gap outside. The self-locking characteristic of the gear engagement structure keeps the smoke gathering side plate 5 fixed after being accommodated in place, avoids accidental unfolding caused by gravity or vibration, and at the same time, the panel 3 is tightly attached to the smoke collecting cavity 1 after being closed, so that the overall structure of the smoke machine is more compact.
