Description

Technical Field

[0001] This invention relates to the field of range hood technology, and in particular to a smoke baffle control method and a smoke baffle radar system. Background Technology

[0002] The opening angle of the baffle plate on a range hood is usually adjustable to open or close. To prevent fingers from being pinched during the closing process, infrared sensors are typically used to detect if any foreign objects are trapped, or changes in the drive current of the motor that moves the push rod are monitored. However, infrared sensors are less resistant to grease and require a relatively clean environment for both the transmitter and receiver. The kitchen's fume extraction area is the most contaminated area, which can easily affect the transmission and reception of infrared signals. Furthermore, monitoring changes in the drive motor's current can lead to significant fluctuations in the current after prolonged operation, potentially causing false alarms. Summary of the Invention

[0007] Based on the comparison results, control the movement of the smoke baffle.

[0008] In an optional embodiment, the smoke deflector radar system is connected to an alarm device, which controls the movement of the smoke deflector based on the comparison result, including:

[0009] If the comparison results indicate that there is a target object in the target area of ​​the first radar image, the distance between the target object and the smoke deflector is determined, and the target object is an object that obstructs the smoke deflector from closing;

[0010] If the distance is greater than the preset distance, the smoke baffle will slow down its movement and the alarm device will play a warning sound.

[0011] If the distance is not greater than the preset distance, control the smoke baffle to stop moving.

[0012] In an optional embodiment, controlling the movement of the smoke baffle based on the comparison results further includes:

[0045] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0046] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0047] Various exemplary embodiments, features, and aspects of this disclosure will now be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise. The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0048] In this document, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Furthermore, the term "at least one" in this document means any combination of at least two of any one or more elements. For example, including at least one of A, B, and C can mean including any one or more elements selected from the set consisting of A, B, and C.

[0049] Furthermore, to better illustrate this disclosure, numerous specific details are set forth in the following detailed description. Those skilled in the art will understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well known to those skilled in the art have not been described in detail in order to highlight the main points of this disclosure.

[0050] In related technologies, the detection of whether foreign objects are trapped when the smoke baffle closes is generally achieved by adding an infrared sensor, or by monitoring changes in the drive current of the motor that moves the push rod. However, infrared sensors are relatively weak against oil contamination, and the signal transmitter and receiver require a relatively clean environment. The kitchen fume extraction area is the most polluted area, which can easily affect the transmission and reception of infrared signals. Furthermore, the method of detecting foreign objects by monitoring changes in the drive motor current can lead to misjudgments after prolonged operation, as the drive current changes significantly.

[0051] In order to improve the efficiency of foreign object identification during the closing process of the smoke baffle and reduce the occurrence of hand pinching, this disclosure provides a smoke baffle control method.

[0052] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application environment according to an exemplary embodiment, such as... Figure 1 As shown, the application environment may include controller 01 and terminal 02.

[0053] In an optional embodiment, the controller 01 can be used for calculation processing in the smoke baffle control method. Specifically, the controller 01 can be a control board or controller installed on the inner wall of the smoke baffle.

[0054] In an optional embodiment, terminal 02 can perform calculations in conjunction with the smoke deflector control method of controller 01, such as acquiring a first radar image. Specifically, terminal 02 may include, but is not limited to, a smoke deflector radar system.

[0055] For example, terminal 02 acquires a first radar image, which is a radar image acquired by at least three radar devices during the closing process of the smoke baffle, and transmits the acquired radar image to controller 01. Controller 01 compares the first radar image with a second radar image to obtain a comparison result. The second radar image is a pre-stored radar image of the smoke baffle radar system. Based on the comparison result, the movement of the smoke baffle is controlled.

[0056] In addition, it should be noted that, Figure 1 The example shown is merely one application environment provided by this disclosure. In practical applications, other application environments may also be included.

[0057] In the embodiments described in this specification, the controller 01 and the terminal 02 can be directly or indirectly connected via wired or wireless communication, and this disclosure does not impose any restrictions.

[0058] Figure 2 This is a flowchart illustrating a smoke deflector control method according to an exemplary embodiment. The smoke deflector is equipped with a smoke deflector radar system, which includes at least three radar devices. The method includes:

[0059] Step S201: Acquire a first radar image, which is a radar image acquired by at least three radar devices during the smoke baffle closing process.

[0060] In this embodiment of the disclosure, acquiring the first radar image includes:

[0061] Step S2011: When the smoke baffle is in the closing process, acquire the first radar image based on a preset time interval.

[0062] In this embodiment of the disclosure, when the smoke baffle begins its opening and closing process, at least three radar devices in the smoke baffle radar system are activated and acquire a first radar image based on a preset time interval. Optionally, when the preset time interval is 1 second, the at least three radar devices in the smoke baffle radar system acquire the first radar image every 1 second, or when the smoke baffle is closing, the first radar image is acquired whenever the angle between the smoke baffle and the horizontal or vertical direction is a preset angle. Optionally, each radar device in the smoke baffle radar system may be an acoustic radar.

[0063] As can be seen from the above, the present invention, by acquiring a first radar image based on a preset time interval when the smoke baffle is in the closed process, can acquire more image information, which makes it easier to more accurately determine whether there are foreign objects obstructing the smoke baffle.

[0064] Step S202: Compare the first radar image with the second radar image to obtain the comparison result. The second radar image is a pre-stored radar image of the smoke deflector radar system.

[0065] In this embodiment of the disclosure, the second radar image is a pre-stored radar image of the smoke deflector radar system. The pre-stored radar image does not contain any foreign objects that would obstruct the closure of the smoke deflector. Comparing the first radar image with the second radar image can be done by comparing the target area in the first radar image with the target area in the second radar image. The target area is the interference zone of the smoke deflector movement.

[0066] Step S203: Control the movement of the smoke baffle based on the comparison results.

[0067] In this embodiment of the disclosure, the smoke deflector radar system is connected to an alarm device, and controls the movement of the smoke deflector based on the comparison results, including:

[0068] Step S2031: If the comparison result indicates that there is a target object in the target area of ​​the first radar image, determine the distance between the target object and the smoke deflector. The target object is an object that obstructs the smoke deflector from closing.

[0069] In this embodiment of the disclosure, the target object may be the user's hand or an object on the stove located in the motion interference zone of the smoke baffle.

[0070] Step S2032: When the distance is greater than the preset distance, control the smoke baffle to slow down its movement speed and control the alarm device to play a prompt sound.

[0071] In this embodiment of the present disclosure, if the distance is greater than the preset distance, the object will not collide with the smoke baffle in a short period of time. At this time, the smoke baffle is lowered to slow down the movement speed, and the alarm device is controlled to play a prompt sound to remind the user to move the target object away.

[0072] Step S2033: When the distance is not greater than the preset distance, control the smoke baffle to stop moving.

[0073] In this embodiment of the disclosure, if the distance is not greater than the preset distance, a collision will occur with the smoke baffle in a short time. At this time, the smoke baffle is controlled to stop moving to avoid collision or pinching of the hand.

[0074] As can be seen from the above, this embodiment of the present disclosure controls the smoke baffle to slow down its movement speed and controls the alarm device to play a prompt sound when the distance is greater than a preset distance, which can promptly remind the user to move the target object; when the distance is not greater than the preset distance, it controls the smoke baffle to stop moving, which can prevent collisions or pinching of hands.

[0075] In an optional embodiment, controlling the movement of the smoke baffle based on the comparison results further includes:

[0076] Step S2034: If the comparison result indicates that there is no target object in the target area of ​​the first radar image, control the smoke deflector to maintain its closed movement.

[0077] In this embodiment of the present disclosure, if the comparison result indicates that there is no target object in the target area of ​​the first radar image, it means that the smoke baffle can be closed normally. Then, the smoke baffle is controlled to continue closing until the smoke baffle is completely closed.

[0078] In one specific embodiment, a schematic diagram of the above-described smoke baffle control method is shown below. Figure 3 As shown:

[0079] The main principle of this solution is to use a radar system installed on the smoke baffle to detect whether there are any foreign objects in the danger zone, i.e., the smoke baffle's movement interference zone, during the closing process. If so, the alarm device of the danger alarm system is triggered, and the smoke baffle is closed only after the foreign object is no longer in the danger zone.

[0080] 1. The smoke baffle begins to close, and the radar system begins to operate;

[0081] 2. Compare with the pre-stored radar image to detect any differences and determine if there are any foreign objects.

[0082] 3. If no foreign object is detected, close the smoke baffle normally.

[0083] 4. If a foreign object is detected within the monitoring range, the system will issue an alarm sound and slow down the closing speed of the smoke baffle. If the location is determined to be very close, the closing action of the smoke baffle will stop.

[0084] Figure 4 This is a block diagram of a smoke deflector radar system control device according to an exemplary embodiment, with reference to... Figure 4 The device includes an acquisition module 401, a comparison module 402, and a control module 403, wherein...

[0085] The acquisition module 401 is used to acquire a first radar image, which is a radar image acquired by at least three radar devices during the closing process of the smoke baffle.

[0086] The comparison module 402 is used to compare the first radar image with the second radar image to obtain the comparison result. The second radar image is a pre-stored radar image of the smoke deflector radar system.

[0087] The control module 403 is used to control the movement of the smoke baffle based on the comparison results.

[0088] In an optional embodiment, the smoke deflector radar system is connected to an alarm device, and the control module 403 includes:

[0089] The first control submodule is used to determine the distance between the target object and the smoke deflector when the comparison result indicates that there is a target object in the target area of ​​the first radar image. The target object is an object that prevents the smoke deflector from closing.

[0090] The deceleration module is used to control the smoke baffle to slow down its movement speed when the distance is greater than a preset distance, and to control the alarm device to play a warning sound.

[0091] The stop module is used to control the smoke baffle to stop moving when the distance is not greater than a preset distance.

[0092] In an optional embodiment, the control module 403 further includes:

[0093] The second control submodule is used to control the smoke deflector to remain closed when the comparison result indicates that there is no target object in the target area of ​​the first radar image.

[0094] In an optional embodiment, the acquisition module 401 includes:

[0095] The acquisition submodule is used to acquire the first radar image based on a preset time interval when the smoke baffle is in the closing process.

[0096] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0097] Figure 5 This is a schematic diagram of a smoke deflector radar system according to an exemplary embodiment, such as...

[0099] As can be seen from the above, the present invention, by having at least three radar devices 1 installed on the inner wall of the smoke baffle 2, enables at least three radar devices 1 to move with the movement of the smoke baffle, and to timely and accurately determine whether there are foreign objects obstructing the closing of the smoke baffle.

[0100] In an optional embodiment, the upper edge of the smoke baffle 2 is connected to the range hood housing, such as...

[0101] In this embodiment, the raised structure 3 on the inner wall of the smoke baffle 2 is a raised platform. The outer shell of the raised structure 3 includes an outer plate surface 301 and a connecting surface 302. The outer plate surface 301 is a rectangular planar structure, parallel to the inner wall of the smoke baffle 2.

Figure 7 Region a1 is the detection area of ​​the first radar device 101. Specifically, the first radar device 101 is located in the middle of the first surface. The second radar device 102 is located on the second surface of the connecting surface 302. The second surface is parallel to the right edge of the smoke baffle 2, and the direction of the second radar device 102 is towards the right edge of the smoke baffle 2. Figure 7The a2 area in the diagram is the detection area of ​​the second radar device 102. Specifically, the second radar device 102 is located in the middle of the second surface. Optionally, the first and second surfaces are respectively provided with mounting portions that match the first radar device 101 and the second radar device 102 for mounting the first radar device 101 and the second radar device 102.

[0104] Based on the above, the present embodiment of the invention, by respectively disposing the first radar device 101 and the second radar device 102 on the first surface and the second surface of the connecting surface 302 that are parallel to the side edge of the smoke baffle 2, can detect the closing process of the left and right side edges of the smoke baffle 2 and prevent foreign objects from being trapped in the closing process of the left and right side edges of the smoke baffle 2.

[0105] In an optional embodiment, at least three radar devices 1 further include: a third radar device 103; the third radar device 103 is disposed on a third surface in the connecting surface 302, the third surface being a surface parallel to the lower edge of the smoke baffle 2.

If the comparison result indicates that there is a target object in the target area of ​​the first radar image, the distance between the target object and the smoke baffle is determined. The target object is the object that obstructs the closing of the smoke baffle. If the distance is greater than a preset distance, the smoke baffle is controlled to slow down its movement speed, and the alarm device is controlled to play a prompt sound.
