Description

Technical Field

[0001] This application relates to the field of range hood technology, and in particular to a range hood and its control method. Background Technology

[0002] As a type of kitchen appliance, a range hood is generally installed above the stove. When users cook food, oil fumes are generated, which are then extracted by the range hood and discharged outdoors. In addition, to ensure that users have good lighting during the cooking process, the range hood is equipped with corresponding lights.

[0003] Currently, traditional range hood lights either have a fixed point of intersection between the light beam and the center line of the cookware, or no intersection at all (the lights are positioned on the left and right sides and are not aligned with the center of the burner). This cannot adapt to changes in the precise lighting requirements (the point of intersection between the light beam and the center line of the cookware). As the height of the cookware changes, so does the precise lighting requirement; as the cookware is placed to the left or right, the precise lighting requirement also changes. Therefore, situations may arise where the precise lighting requirement is not met, meaning the center of the cookware is not illuminated. This results in difficulty seeing the inside of the cookware while cooking, leading to poor lighting performance. Summary of the Invention

[0004] This application provides a range hood and its control method, which solves the problem of poor lighting effect of the range hood.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a range hood, which includes a body, a panel, a light source, a mounting base, and a drive assembly. The panel is mounted on the body and fixed relative to the body; the mounting base is located inside the panel; the drive assembly is connected to the body and located inside the panel, and is connected to the mounting base, capable of driving the mounting base to move, so that the mounting base can move inside the panel, and preventing the drive assembly and the mounting base from being corroded by oil fumes; the light source is located outside the panel, and the light source can be magnetically connected to the mounting base and can move with the mounting base, so that the light source can move on the outside of the panel under the action of the drive assembly.

[0007] The technical solution provided in this application brings at least the following beneficial effects: the drive component drives the mounting base to move, which in turn moves the lighting lamp on the panel, enabling the lighting lamp to quickly reach the precise lighting requirement point, that is, to illuminate the center of the cookware, so that the situation inside the cookware can be clearly seen during cooking, thereby improving the lighting effect of the range hood.

[0008] In some embodiments, the range hood provided in this application further includes a temperature detection component and a controller. The temperature detection component is connected to the mounting base and is used to detect the temperature value at the location of the mounting base; the controller is electrically connected to each of the temperature detection component and the drive component. The controller is configured to: acquire the temperature value detected by the temperature detection component; and control the drive component to start based on the temperature value detected by the temperature detection component, so as to drive the mounting base to move. In this embodiment, the range hood can determine the position on the panel where the lighting needs to be moved based on the temperature value detected by the temperature detection component, control the drive component to start, drive the mounting base to move to that position, and then move the lighting with the mounting base to that position, thereby intelligently adjusting the position of the lighting so that the lighting can quickly reach the precise lighting requirement point, that is, quickly illuminate the center of the cookware.

[0009] In some embodiments, the temperature detection component is connected to the mounting base and is used to detect the temperature value at the location of the mounting base; the controller is electrically connected to each of the temperature detection component and the drive component, and the controller is configured to: acquire the temperature value detected by the temperature detection component; control the drive component to start, and drive the mounting base to move sequentially to a first position, a second position, and a third position in the horizontal direction; control the drive component to stop when the mounting base reaches the third position; and control the drive component to start according to the temperature value detected by the temperature detection component, so as to drive the mounting base to move. In this embodiment, the range hood can determine which burner is on or which burner corresponds to the highest pot temperature based on the temperature value detected by the temperature detection component.

[0010] In some embodiments, the controller executes the function of controlling the drive component to start based on the temperature value detected by the temperature detection component, and is configured to:

[0011] If the temperature value detected by the temperature detection component at the first position is greater than the temperature values ​​detected at the second and third positions, the drive component is activated, and the drive mounting base moves to the first position and then stops. If the temperature value detected by the temperature detection component at the second position is greater than the temperature values ​​detected at the first and third positions, the drive component is activated, and the drive mounting base moves to the second position and then stops. If the temperature value detected by the temperature detection component at the third position is greater than the temperature values ​​detected at the first and second positions, the drive component is activated, and the drive mounting base moves to the third position and then stops. In this embodiment, the range hood can move the lighting lamp to the position with the highest temperature detected by the temperature detection component based on the temperature value detected by the temperature detection component.

[0012] In some embodiments, the temperature detection component includes at least four temperature sensors, which are spaced apart along an arc direction, with equal distance between any two adjacent temperature sensors, and the sum of the temperature values ​​detected by any two adjacent temperature sensors is a first sum number.

[0013] The controller executes the start of the drive component based on the temperature value detected by the temperature detection component, and is also configured to start the drive component if the difference between any two first sums is greater than a first preset value.

[0014] If there are two first sums whose difference is less than or equal to a first preset value, and if the difference between the temperature values ​​detected by any two adjacent temperature sensors is less than or equal to a second preset value, the control drive component stops.

[0015] If the difference between two first sums is less than or equal to a first preset value, and the difference between the temperature values ​​detected by two adjacent temperature sensors is greater than a second preset value, the drive component is activated, wherein the first preset value is greater than the second preset value. In this embodiment, the range hood can determine whether the lighting has moved to the precise lighting requirement point, i.e., whether the light shines on the center of the cookware, based on the temperature value detected by the temperature detection component. If the temperature value detected by each of at least four temperature sensors is less than or equal to the second preset value, the light shines on the center of the cookware; if the light shines on the center of the cookware, the drive component stops; otherwise, the drive component is activated, and the lighting continues to move.

[0016] In some embodiments, the controller executes the following: if the difference between any two first sums is greater than a first preset value, the controller activates the drive component, configured to: determine a first orientation based on the sum of temperature values ​​detected by every two adjacent temperature sensors, wherein the first orientation is the orientation of the two adjacent temperature sensors with the largest sum of temperature values; activate the drive component, and drive the mounting base to move toward the first orientation. In this embodiment, the range hood can determine the first orientation based on the sum of temperature values ​​detected by every two adjacent temperature sensors, and the drive component drives the mounting base to move toward the first orientation, thereby shortening the time it takes for the lighting lamp to reach the precise lighting requirement point.

[0017] In some embodiments, if the difference between two first sums is less than or equal to a first preset value, and the difference between two adjacent temperature values ​​detected by the temperature sensors is greater than a second preset value, the controller activates the drive assembly, configured to: determine a second orientation based on the temperature values ​​detected by at least four temperature sensors, the second orientation being the orientation of the temperature sensor with the highest detected temperature value; activate the drive assembly, and drive the mounting base to move toward the second orientation. In this embodiment, the range hood can determine the second orientation based on the temperature values ​​detected by at least four temperature sensors, and the drive assembly drives the mounting base to move toward the first orientation, thereby shortening the time it takes for the lighting lamp to reach the precise lighting requirement point.

[0018] In some embodiments, the lighting fixture includes a base plate, a lampshade, a battery, a light-emitting element, and a first magnet. A light-emitting cavity is formed between the base plate and the lampshade; the battery is disposed within the light-emitting cavity; the light-emitting element is disposed within the light-emitting cavity and electrically connected to the battery; the first magnet is connected to the base plate; the mounting base includes a base body and a second magnet. The base body is connected to a drive assembly; the second magnet is connected to the base body and can be magnetically connected to the first magnet. In this embodiment, the magnetic connection between the first and second magnets allows for flexibility in the materials of the mounting base and the base plate, and makes the magnetic connection between the mounting base and the lighting fixture more stable, preventing the lighting fixture from falling off.

[0019] In some embodiments, the range hood further includes a wireless charging component and a third magnet. The wireless charging component includes a wireless charging transmitter and a wireless charging receiver. The wireless charging transmitter is connected to the main body and located inside the panel. The wireless charging receiver is disposed within the light-emitting cavity and electrically connected to the battery. The third magnet is connected to the main body and located inside the panel. The third magnet can magnetically connect with the first magnet. When the second magnet is magnetically connected with the first magnet, the light fixture can move relative to the mounting base. When the third magnet is magnetically connected with the first magnet, the wireless charging transmitter and the wireless charging receiver correspond to each other, so that the wireless charging receiver receives electrical energy from the wireless charging transmitter and transmits the electrical energy to the battery. In this embodiment, the magnetic connection between the first and second magnets enables the movement of the light fixture; the magnetic connection between the first and third magnets enables the wireless charging transmitter to magnetically connect with the wireless charging receiver in the light fixture, thereby achieving wireless charging of the light fixture.

[0020] In some embodiments, the range hood further includes an oil guide ring, which is sleeved on the base plate. The inner circumferential surface of the oil guide ring is connected to the base plate, and the outer circumferential surface of the oil guide ring is conical. The radial dimension of the oil guide ring gradually decreases in the direction away from the panel. In this embodiment, the outer circumferential surface of the oil guide ring is conical, and the radial dimension of the oil guide ring gradually decreases in the direction away from the panel, ensuring that the condensed oil flows smoothly down and does not flow back into the lighting lamp. It also absorbs shock when attracted by the first magnet, thereby protecting the panel and the lighting lamp.

[0021] Secondly, this application provides a control method for a range hood, which is used in the range hood of the first aspect. The control method includes: acquiring a temperature value detected by the temperature detection component; and controlling the drive component to start based on the temperature value detected by the temperature detection component, so as to drive the mounting base to move.

[0022] Thirdly, this application provides a controller, comprising: one or more processors; one or more memories; wherein the one or more memories are used to store computer program code, the computer program code including computer instructions, and when the one or more processors execute the computer instructions, the controller executes the control method for the range hood provided in the second aspect and possible implementations.

[0023] Fourthly, this application provides a computer-readable storage medium including computer instructions that, when executed on a computer, cause the computer to perform the control method for the range hood provided in the second aspect and possible implementations.

[0024] Fifthly, embodiments of the present invention provide a computer program product that can be directly loaded into a memory and contains software code. After being loaded and executed by a computer, the computer program product can realize the range hood control method provided in the second aspect and possible implementations.

[0025] It should be noted that the aforementioned computer instructions may be stored, in whole or in part, on a computer-readable storage medium. This computer-readable storage medium may be packaged together with the controller's processor, or it may be packaged separately from the controller's processor; this application does not impose any limitations on this.

Detailed Implementation

[0043] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0044] In the description of this invention, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0045] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, when describing pipelines or channels, the terms "connection" and "linking" used in this application have the meaning of establishing electrical conductivity. The specific meaning needs to be understood in conjunction with the context.

[0047] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0048] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0049] As a type of kitchen appliance, a range hood is generally installed above the stove. When users cook food, oil fumes are generated, which are then extracted by the range hood and discharged outdoors. In addition, to ensure that users have good lighting during the cooking process, the range hood is equipped with corresponding lights.

[0050] As living standards improve, consumers have higher expectations for the user experience of range hoods, making more intelligent operation a primary research and development goal for the industry. Currently, traditional range hood lights either have a fixed or no intersection point between the light beam's center and the cookware's center line (the lights are positioned on the left and right sides and are not aligned with the burner's center), failing to adapt to changes in the precise lighting requirements (the intersection of the light beam and the cookware's center line). The precise lighting requirement changes with the height of the cookware and also with its left-right placement. Therefore, the precise lighting requirement may not be met, meaning the center of the cookware may not be illuminated, making it difficult to see inside the cookware while cooking.

[0051] The technical solution of this application upgrades and improves the structure of existing range hoods by adding a mounting base and a drive assembly, allowing the lighting fixture to move. A temperature detection assembly is also added to measure the temperature at the location of the mounting base. Based on this temperature, the position of the lighting fixture on the panel can be determined, and the range hood controller can then control the drive assembly to move the mounting base, thus controlling the movement of the lighting fixture. This allows the lighting fixture to quickly reach the precise lighting point, positioned above the stove burner or cookware, illuminating the center of the cookware. This improves visibility during cooking and enhances the lighting effect of the range hood.

[0052] like Figure 1 As shown and Figure 2 As shown, the range hood 1 provided in this embodiment includes a body 10, a panel 11, a light 20, a mounting base 30, and a drive assembly 40. The panel 11 is mounted on the body 10 and fixed relative to the body 10. The mounting base 30 is located on the inner side of the panel 11. The drive assembly 40 is connected to the body 10 and located on the inner side of the panel 11. The drive assembly 40 is connected to the mounting base 30 and can drive the mounting base 30 to move, so that the mounting base 30 can move on the inner side of the panel 11, and can prevent the drive assembly 40 and the mounting base 30 from being corroded by oil fumes. The light 20 is located on the outer side of the panel 11. The light 20 can be magnetically connected to the mounting base 30 and can move with the mounting base 30, so that the light 20 can move on the outer side of the panel 11 under the action of the drive assembly 40.

[0053] For example, such as Figure 2 andFigure 3 As shown, the drive assembly 40 includes a first motor 41, a second motor 42, a first gear 43, a second gear 44, a first rack 45, a second rack (not shown in the figure), and a drive frame 46. The drive frame 46 is aligned with the body 10 along a first direction (…). Figure 2 Sliding connection in the X direction, and / or, drive frame 46 and panel 11 along the first direction ( Figure 2 The first rack 45 is fixed to the panel 11 in the X direction. The first motor 41 is fixed to the drive frame 46. The output shaft of the first motor 41 is connected to the first gear 43, and the first gear 43 cooperates with the first rack 45. While the first motor 41 drives the first gear 43 to rotate, the first motor 41, the first gear 43, and the drive frame 46 move relative to the panel 11 in the first direction (X direction). Figure 2 Move in the X direction.

[0054] Furthermore, the mounting base 30 and the drive frame 46 are along the second direction ( Figure 3 The second rack is slidably connected in the Y direction, and the second motor 42 is fixedly connected to the mounting base 30. The output shaft of the second motor 42 is connected to the second gear 44, which engages with the second rack so that the second motor 42 can drive the second rack along the second direction (Y direction). Figure 3 The mounting base 30 can move along the second direction (Y direction) to move the Y direction. Since the mounting base 30 is located inside the panel 11, it can move along the first direction inside the panel 11 and also along the second direction. Since the lighting lamp 20 is located outside the panel 11, it can be magnetically connected to the mounting base 30 and can move with the mounting base 30. The lighting lamp 20 can move along the first direction outside the panel 11 with the mounting base 30 and also along the second direction.

[0055] It should be noted that the mounting base 30 can also be driven to move along the first and second directions by other driving methods.

[0056] In this way, the drive component 40 drives the mounting base 30 to move, which in turn moves the lighting lamp 20 on the panel 11, enabling the lighting lamp 20 to quickly reach the precise lighting requirement point, that is, to illuminate the center of the pot, so that the situation inside the pot can be clearly seen during cooking, thereby improving the lighting effect of the range hood 1.

[0057] In addition, the lighting lamp 20 can be magnetically connected to the mounting base 30, which allows the lighting lamp 20 to be removed and placed separately. If it is damaged, it can be repaired or replaced separately without disassembling the entire range hood. It also makes it easy to clean the panel 11 and the lighting lamp 20.

[0058] Based on this, such as Figure 3 and Figure 4As shown, the lighting lamp 20 includes a base plate 21, a lampshade 22, a battery 23, a light-emitting element 24, a first magnet 25, and a circuit board 29. A light-emitting cavity 26 is formed between the base plate 21 and the lampshade 22. The battery 23 is disposed within the light-emitting cavity 26, and the light-emitting element 24 is disposed within the light-emitting cavity 26 and fixed to the base plate 21. Both the battery 23 and the light-emitting element are electrically connected to the circuit board 29, and the battery 23 can supply power to the light-emitting element 24 through the circuit board 29. The first magnet 25 is connected to the base plate 21. The mounting base 30 includes a base body 31 and a second magnet 32. The base body 31 is connected to the drive assembly 40, and the second magnet 32 ​​is connected to the base body 31 and can be magnetically connected to the first magnet 25, so that the lighting lamp 20 can be magnetically connected to the mounting base 30. In this way, the magnetic connection between the first magnet 25 and the second magnet 32 ​​allows the material of the mounting base 30 and the base plate 21 to be unrestricted, and makes the magnetic connection between the mounting base 30 and the lighting lamp 20 more stable, thus preventing the lighting lamp 20 from falling off.

[0059] It is understandable that, such as Figure 4 As shown, a lighting switch 210 is provided on the base plate 21. The base plate has a through hole, and the lighting switch 210 is located in the through hole. That is, it can prevent the lighting switch 210 from interfering with the panel 11 and causing accidental switching.

[0060] In addition, the lighting lamp 20 also includes a reflector 28, which is disposed in the light-emitting cavity 26 and connected to the base plate 21. The reflector 28 is disposed opposite to the lamp cover 22. The center of the reflector 28 is provided with a mounting hole, through which the light-emitting element 24 passes. Most of the light emitted by the light-emitting element 24 is emitted through the transparent lamp cover 22, and part of the light is reflected by the reflector 28 and emitted through the lamp cover 22.

[0061] For example, the light-emitting element 24 can be an LED lamp bead or other light-emitting device, which is not limited here.

[0062] In some embodiments, to achieve wireless charging of the lighting lamp 20, such as Figure 5 and Figure 6 As shown, the range hood 1 also includes a wireless charging assembly 50 and a third magnet 60. The wireless charging assembly 50 includes a wireless charging transmitter 51 and a wireless charging receiver 52. The wireless charging transmitter 51 is connected to the body 10 and located inside the panel 11, used to transmit electrical energy to the wireless charging receiver 52. The wireless charging receiver 52 is located inside the light-emitting cavity and electrically connected to the circuit board 29, used to receive the electrical energy from the wireless charging transmitter 51 and transmit the electrical energy to the battery 23 through the circuit board 29. The third magnet 60 is connected to the body 10 and located inside the panel 11. The third magnet 60 can be magnetically connected to the first magnet 25, so that the wireless charging transmitter 51 is magnetically connected to the wireless charging receiver 52 in the lighting lamp 20.

[0063] When the second magnet 32 ​​is magnetically connected to the first magnet 25, the lighting lamp 20 can move relative to the mounting base 30. When the third magnet 60 is magnetically connected to the first magnet 25, the wireless charging transmitter 51 is magnetically connected to the wireless charging receiver 52 in the lighting lamp 20. The wireless charging transmitter 51 and the wireless charging receiver 52 correspond to each other, so that the wireless charging receiver 52 receives the electrical energy from the wireless charging transmitter 51 and transmits the electrical energy to the battery 23.

[0064] In this way, through the magnetic connection between the first magnet 25 and the third magnet 60, the wireless charging transmitter 51 can be magnetically connected to the wireless charging receiver 52 in the lighting lamp 20, thereby realizing wireless charging of the lighting lamp 20.

[0065] To prevent the condensed oil produced during the operation of the range hood 1 from flowing back into the lighting lamp 20, such as Figure 7 As shown, the range hood 1 also includes an oil guide ring 27, which is sleeved on the base plate 21. The inner circumferential surface of the oil guide ring 27 is connected to the base plate 21, and the outer circumferential surface of the oil guide ring 27 is a conical surface. The radial dimension of the oil guide ring 27 gradually decreases in the direction away from the panel 11, ensuring that the condensed oil flows down smoothly and does not flow back into the lamp 20. It can also absorb shock when attracted by the first magnet 25, thereby protecting the panel 11 and the lamp 20.

[0066] To facilitate adjusting the position of the lighting lamp 20, such as Figure 8 As shown, the range hood 1 provided in this application also includes a temperature detection component 70 and a controller (not shown in the figure). The temperature detection component 70 is connected to the mounting base 30 and is used to detect the temperature value at the location of the mounting base 30. The controller is electrically connected to each of the temperature detection component 70 and the drive component 40. The controller can acquire the temperature value detected by the temperature detection component 70, and the controller of the range hood 1 can control the drive component 40 to start according to the temperature value detected by the temperature detection component 70, so as to drive the mounting base 30 to move.

[0067] It is understandable that, such as Figure 9 As shown, the range hood of this application is used in conjunction with a cooktop. When the cooktop is working, the air above it transfers heat, creating a relative temperature field 100 on the panel 11. The center of the temperature field 100 corresponds to the burner position of the cooktop, and is typically located above the burner. The mounting base 30 is situated within this temperature field 100, and the temperature detection component 70 is fixed to the base 31 of the mounting base 30. The temperature value detected by the temperature detection component 70 reflects the position of the mounting base 30.

[0068] In this way, the controller of the range hood 1 can obtain the position of the mounting base 30 and the light 20 on the panel 11 based on the temperature value detected by the temperature detection component 70, and can determine whether the current position is the ideal position. The controller of the range hood 1 can also control the drive component 40 to start, so as to drive the mounting base 30 to move to a higher temperature position, and then the light 20 moves to that position with the mounting base 30, so as to facilitate the adjustment of the position of the light 20, so that the light 20 can quickly reach the precise lighting requirement point, that is, reach the stove burner or the pot, so that the light quickly shines on the center of the pot.

[0069] In some embodiments, see Figure 8 and Figure 9 The temperature detection assembly 70 includes at least four temperature sensors 71, which are spaced apart along an arc direction, with equal distance between any two adjacent temperature sensors 71. That is, the at least four temperature sensors 71 are arranged in a circular array, and the line formed by connecting the at least four temperature sensors 71 in sequence is a complete circle.

[0070] Understandably, arranging at least four temperature sensors 71 in a circular array can improve the detection accuracy of the temperature detection component 70. Furthermore, by comparing the temperature values ​​detected by at least four temperature sensors 71, the orientation of the mounting base 30 / lighting lamp 20 within the temperature field 100 can be confirmed. The temperature values ​​detected by the temperature sensors 71 closer to the center of the temperature field 100 are higher.

[0071] In this way, the controller of the range hood 1 can determine the current position of the mounting base 30 and the lighting lamp 20 based on the temperature value detected by the temperature detection component 70, and can control the drive component 40 to drive the mounting base 30 to move closer to the center of the temperature field 100, with the lighting lamp 20 moving along with the mounting base 30. Therefore, the range hood 1 of this application can use the controller to control the drive component 40, so that the mounting base 30 and the lighting lamp 20 can be accurately moved to the precise lighting requirement point, that is, the mounting base 30 and the lighting lamp 20 can be accurately moved to the center of the cookware.

[0072] Based on the range hood 1 described above, the control method of the range hood according to an embodiment of this application will be described below with reference to the accompanying drawings. This method is applied to a controller, which can be the controller described above.

[0073] This application also provides a control method for a range hood, such as... Figure 10 As shown, the method includes the following steps:

[0074] S100, The controller acquires the temperature value detected by the temperature detection component.

[0075] When the range hood's lighting program is activated, the controller activates the lights and the temperature detection component. The lights and temperature detection component operate until the lighting program ends. In one possible implementation, the lighting program can be triggered by the user, meaning the user controls the activation of the lighting program.

[0076] For example, a user can control the start of the dryer program by operating the display panel of the touch-screen range hood.

[0077] For example, users can also establish a communication connection with the range hood via a mobile device, thereby controlling the activation of the lighting program on the mobile device. For instance, the mobile device can establish a communication connection with the range hood via WiFi or Bluetooth modules.

[0078] In addition, the controller is connected to a temperature detection component, which can transmit the detected temperature signal to the controller in real time, and the controller can receive the temperature signal.

[0079] S200, the controller starts the drive assembly, and the drive mounting base is in the horizontal direction (e.g., Figure 3 The Y-direction (in the middle) moves sequentially to the first position, the second position, and the third position.

[0080] The controller controls the second motor to start, and the second motor can drive the mounting base to move horizontally through the cooperation of the second gear and the second rack, and pass through the first position, the second position and the third position in sequence.

[0081] Understandably, after the lighting program is started, the controller first controls the drive component to start, and the drive mounting base moves sequentially to the first, second, and third positions along the horizontal direction. Simultaneously, the controller acquires the temperature values ​​detected by the temperature detection component at the first, second, and third positions.

[0082] S300. When the mounting base reaches the third position, control the drive assembly to stop.

[0083] The first, second, and third positions are preset positions. The position information of the first, second, and third positions is stored in the controller in advance. When the mounting base reaches the third position, the controller controls the second motor to stop.

[0084] S400. Based on the temperature value detected by the temperature detection component, control the drive component to start.

[0085] In some embodiments, the controller controls the drive component to start based on the temperature values ​​detected by the temperature detection component at the first, second, and third positions.

[0086] For example, such as Figure 11As shown, the controller compares the temperature values ​​detected by the temperature detection component at the first, second, and third positions.

[0087] Specifically, if the temperature value detected by the temperature detection component at the first position is greater than the temperature values ​​detected at the second and third positions, the drive component is activated, and the drive mounting base stops after moving to the first position. If the temperature value detected by the temperature detection component at the second position is greater than the temperature values ​​detected at the first and third positions, the drive component is activated, and the drive mounting base stops after moving to the second position. If the temperature value detected by the temperature detection component at the third position is greater than the temperature values ​​detected at the first and second positions, the drive component is activated, and the drive mounting base stops after moving to the third position.

[0088] In other words, the controller determines whether the temperature value detected by the temperature detection component at the first position is the maximum. If yes, the controller starts the drive component, and the drive mounting base moves to the first position and then stops. If not, the controller continues to compare the temperature values ​​detected by the temperature detection component at the first, second, and third positions. Similarly, the controller determines whether the temperature value detected by the temperature detection component at the second position is the maximum. If yes, the controller starts the drive component, and the drive mounting base moves to the second position and then stops. If not, the controller continues to compare the temperature values ​​detected by the temperature detection component at the first, second, and third positions. The controller determines whether the temperature value detected by the temperature detection component at the third position is the maximum. If yes, the controller starts the drive component, and the drive mounting base moves to the third position and then stops. If not, the controller continues to compare the temperature values ​​detected by the temperature detection component at the first, second, and third positions.

[0089] Understandably, this application moves the mounting base to the location with the highest temperature among the first, second, and third positions, bringing it closer to the center of the temperature field (the center of the cookware). Furthermore, by moving the mounting base to the location with the highest temperature among the first, second, and third positions, this application allows for fuzzy judgment, bringing the mounting base closer to the center of the temperature field. This shortens the time required for subsequent precise judgment, thereby reducing the time it takes for the lighting fixture to reach the precise lighting requirement point.

[0090] In some embodiments, after the mounting base moves to the position with the highest temperature among the first, second, and third positions, the controller controls the drive component to start based on the temperature value detected by the temperature detection component, so that the mounting base moves accurately to the center of the temperature field. At the same time, the lighting lamp reaches the precise lighting requirement point. That is, this application can make accurate judgments through control.

[0091] For example, such as Figure 12As shown, the sum of the temperature values ​​detected by any two adjacent temperature sensors is the first sum. If the difference between any two first sums is greater than a first preset value, the control drive component starts; if the difference between two first sums is less than or equal to the first preset value, and the difference between the temperature values ​​detected by any two adjacent temperature sensors is greater than or equal to a second preset value, the control drive component stops; if the difference between two first sums is less than or equal to the first preset value, and the difference between the temperature values ​​detected by any two adjacent temperature sensors is less than or equal to the second preset value, the control drive component stops starting. The first preset value is greater than or equal to the second preset value, and the first preset value is greater than or equal to 3℃ and less than or equal to 7℃, and the value of the first preset value can be 3℃, 4℃, 5℃, 6℃, 7℃, etc.; the second preset value is greater than or equal to 0.5℃ and less than or equal to 1.5℃, and the value of the second preset value can be 0.5℃, 1℃, 1.5℃, etc.

[0092] In other words, the controller calculates a first sum, which is the sum of the temperature values ​​detected by every two adjacent temperature sensors. The controller first determines whether the difference between any two first sums is greater than a first preset value; if so, the controller controls the drive component to start; if not (if there are two first sums whose difference is less than or equal to the first preset value), the controller then determines whether the difference between the temperature values ​​detected by every two adjacent temperature sensors is greater than or equal to a second preset value.

[0093] If the difference between the temperature values ​​detected by two adjacent temperature sensors is greater than or equal to a second preset value, the controller stops the drive component if the difference is greater than or equal to the second preset value. If not (there is a difference between the temperature values ​​detected by two adjacent temperature sensors that is less than or equal to the second preset value), the controller starts the drive component.

[0094] In some embodiments, such as Figure 13 As shown, if the difference between any two first sums is greater than a first preset value, the controller controls the drive component to start, including the following steps:

[0095] S411, determine the first orientation based on the sum of the temperature values ​​detected by every two adjacent temperature sensors, wherein the first orientation is the orientation of the two adjacent temperature sensors with the largest sum of temperature values.

[0096] Among them, at least four temperature sensors are arranged in a circular array, and the line formed by connecting at least four temperature sensors in sequence is a complete circle.

[0097] For example, the temperature detection component includes four temperature sensors, which detect temperatures of T1, T2, T3, and T4. The controller calculates four sums, namely (T1+T2), (T2+T3), (T3+T4), and (T4+T1). The controller compares (T1+T2), (T2+T3), (T3+T4), and (T4+T1).

[0098] If (T1+T2) is the largest, then the location of temperature sensors T1 and T2 is the first location; if (T2+T3) is the largest, then the location of temperature sensors T2 and T3 is the first location; if (T3+T4) is the largest, then the location of temperature sensors T3 and T4 is the first location; if (T4+T4) is the largest, then the location of temperature sensors T1 and T4 is the first location.

[0099] S412, the control drive component is started, and the drive mounting base moves toward the first position.

[0100] It is understandable that, assuming the temperature sensor 71 has the same accuracy, the larger the diameter of the entire circle, the higher the detection accuracy of the temperature detection component, and consequently, the higher the control accuracy of the controller in controlling the drive component to start. This is because the span of the detection points (temperature sensor 71) in the temperature field is wide, and the direction of the line connecting two detection points (two temperature sensors 71) is easy to determine.

[0101] Furthermore, increasing the diameter of the entire circle leads to poor positioning accuracy at the center. In other words, while increasing the diameter of the entire circle makes it easier to control the start-up of the drive component and bring the drive mounting base closer to the center of the temperature field, it is difficult to move it accurately to the center of the temperature field.

[0102] Based on this, this application can set two sets of temperature sensors, each arranged in a circular array, with the connecting lines between the two sets of temperature sensors forming concentric circles. Based on the temperature value detected by the set of temperature sensors forming the larger circle of the concentric circles, this application can more easily control the start-up of the drive component, and the drive mounting base can be positioned closer to the center of the temperature field. Based on the temperature value detected by the set of temperature sensors forming the smaller circle of the concentric circles, this application can use the drive component to drive the mounting base to accurately move to the center of the temperature field. In this way, the control method of this application can improve control accuracy.

[0103] In some embodiments, such as Figure 14 As shown, if there are two first sums whose difference is less than or equal to a first preset value, and there are two adjacent temperature values ​​detected by the temperature sensors whose difference is greater than a second preset value, the control drive component is activated, including the following steps:

[0104] S421, determine the second orientation based on the temperature values ​​detected by at least four temperature sensors. The second orientation is the orientation of the temperature sensor that detected the highest temperature value.

[0105] Understandably, at this point, the mounting base is already close to the center of the temperature field, and the temperature sensor that detected the largest temperature value is closer to the center of the temperature field. The controller compares the temperature values ​​detected by at least four temperature sensors and determines the location of the temperature sensor that detected the largest temperature value as the second location.

[0106] Furthermore, the control method of this application embodiment can determine the second orientation based on the temperature values ​​detected by a set of temperature sensors forming the small circles in the concentric circles in the above embodiment.

[0107] S422, the control drive component is started and drives the mounting base to move toward the second position.

[0108] It is understood that the control method in this application embodiment utilizes the drive component to move multiple times toward the second position until the mounting base reaches the center of the temperature field. When the mounting base reaches the center of the temperature field, there exists a difference between two first sums that is less than or equal to a first preset value, and the difference between the temperature values ​​detected by any two adjacent temperature sensors is less than or equal to a second preset value.

[0109] It should be noted that the control method in this embodiment utilizes the drive assembly of the range hood to drive the mounting base, and the controller controls the first motor and the second motor. The drive assembly drives the mounting base to move along the first direction and the second direction, moving a preset distance each time. This preset distance is greater than or equal to 2mm and less than or equal to 8mm, and the value of the preset distance can be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.
