[0002] With the continuous development of smart home technology, the interconnected use of various home devices has become an industry trend to better meet people's requirements for their living environment. In particular, to improve the impact of kitchen fumes on indoor air quality, range hoods and air purifiers are often used in conjunction. However, in actual use, the interconnected use of range hoods and air purifiers relies on users manually turning them on. This manual control method cannot scientifically control the air purifier based on actual environmental conditions, potentially leading to low efficiency in improving indoor air quality in the kitchen or unnecessary energy waste. Summary of the Invention

[0003] In view of this, in order to at least solve the technical problem of the lack of scientific control methods for the coordinated use of range hoods and air purifiers, the purpose of this invention is to provide a home interconnection control method, device and system.

[0004] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows:

[0008] When the purifier runs continuously in the same location for a period of time exceeding the first set time, the oil fume concentration value of the area where the range hood is located is obtained;

[0009] When the oil fume concentration value is lower than the set concentration threshold, a control signal is sent to the purifier to reduce the current purification power;

[0010] When the oil fume concentration value is not lower than the concentration threshold, a control signal is sent to the purifier to maintain or increase the current purification power.

[0011] A second aspect of the present invention provides a home interconnection control device, comprising:

[0013] The determination module is configured to: determine, based on the location information, whether the continuous operating time of the purifier at the same location exceeds a first preset duration;

[0014] The concentration acquisition module is configured to acquire the oil fume concentration value of the area where the range hood is located when the purifier runs continuously at the same location for a period of time exceeding the first set time.

[0015] The control module is configured to: send a control signal to the purifier to reduce the current purification power when the oil fume concentration value is lower than a set concentration threshold; and send a control signal to the purifier to maintain or increase the current purification power when the oil fume concentration value is not lower than the set concentration threshold.

[0016] A third aspect of the present invention provides a home interconnection control system, comprising: a range hood, a purifier, multiple visible light communication modules, and a linkage control module;

[0017] The linkage control module is used to communicate with the range hood and the air purifier respectively through the plurality of visible light communication modules, and is used to control the working status of the air purifier through the home interconnection control method provided in the first aspect above.

[0018] A fourth aspect of the present invention provides an electronic device including a processor and a memory, the memory storing machine-executable instructions executable by the processor, the processor executing the machine-executable instructions to implement the home interconnection control method provided in the first aspect above.

[0019] A fifth aspect of the present invention provides a computer-readable storage medium having a computer program stored thereon, wherein the computer program, when executed by a processor, implements the home interconnection control method provided in the first aspect.

Next, when the purifier runs continuously at the same location for a period exceeding a first set time, the oil fume concentration at the range hood is acquired. If the oil fume concentration is lower than a set concentration threshold, the purifier's current purification power is reduced.

When the oil fume concentration is lower than the concentration threshold, the purifier's purification power is reduced in a timely manner, continuing to purify oil fumes while reducing power consumption. Conversely, when the oil fume concentration is not lower than the concentration threshold, the purifier's current purification power is increased or maintained to enhance or maintain its oil fume purification capacity, thereby improving the oil fume purification effect to a certain extent. This achieves scientific linkage control between the range hood and the purifier.

[0021] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0029] To address the technical problem of the lack of scientific control methods for the coordinated use of traditional range hoods and air purifiers, this invention provides a home interconnection control method. By determining whether the continuous operating time of the purifier at the same location exceeds a first preset duration based on the location information of the purifier associated with the range hood during its operation, the method achieves, at the first level, the purification effect of the purifier on cooking fumes is ensured by measuring the operating time of the purifier. Next, when the purifier runs continuously at the same location for a period exceeding a first set time, the oil fume concentration at the range hood is acquired. If the oil fume concentration is lower than a set concentration threshold, the purifier's current purification power is reduced. If the oil fume concentration is not lower than the aforementioned concentration threshold, the purifier's current purification power is maintained or increased. This achieves, at the second level, accurate determination of the purifier's purification effect on dense smoke by combining the oil fume concentration with the operating time, ensuring the purifier's operating time. When the oil fume concentration is lower than the concentration threshold, the purifier's purification power is reduced in a timely manner, continuing to purify oil fumes while reducing power consumption. Conversely, when the oil fume concentration is not lower than the concentration threshold, the purifier's current purification power is increased or maintained to enhance or maintain its oil fume purification capacity, thereby improving the oil fume purification effect to a certain extent. This achieves scientific linkage control between the range hood and the purifier.

[0030] The home interconnection control method provided by this invention can be applied to electronic devices. Please refer to [the relevant documentation]. Figure 1 This is a structural block diagram of an electronic device. The electronic device 100 includes a memory 110, a processor 120, and a communication module 130. The memory 110, processor 120, and communication module 130 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these components can be electrically connected to each other through one or more communication buses or signal lines.

[0031] The memory is used to store programs or data. The memory may be, but is not limited to, Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read-Only Memory (PROM), Erasable Programmable Read-Only Memory (EPROM), Electrically Erasable Programmable Read-Only Memory (EEPROM), etc.

[0032] The processor is used to read / write data or programs stored in memory and to perform the corresponding functions.

[0033] The communication module is used to establish communication connections between electronic devices and other communication terminals via a network, and to send and receive data via the network.

[0034] It should be understood that, Figure 1 The structure shown is only a schematic diagram of an electronic device; the electronic device may also include components that are larger than... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown. Figure 1 The components shown can be implemented using hardware, software, or a combination thereof.

[0035] Before applying the home interconnection control method provided in this embodiment of the invention, an infrastructure capable of interconnecting and controlling the range hood and air purifier can be established in the home environment. For example, a communication path can be established between the range hood, the linkage control module equipped with the home interconnection control method provided in this embodiment of the invention, and the air purifier via wired or wireless communication. Based on this, the linkage control module can serve as a communication medium between the range hood and the air purifier, and by executing the home interconnection control method provided in this embodiment of the invention, it can achieve linkage control of the air purifier's operating state based on the operating state of the range hood.

[0036] The aforementioned linkage control module can be installed as part of the range hood or air purifier, or it can be installed separately from the range hood or air purifier as an independent product. The linkage control module can be implemented using the aforementioned electronic equipment.

[0037] In some embodiments, to simplify wiring operations and reduce wiring difficulty, the linkage control module can communicate with the range hood and air purifier separately via wireless communication. Alternatively, the linkage control module can be integrated into the range hood, communicating with the range hood via wired communication and with the air purifier via wireless communication. Or, the linkage control module can be integrated into the air purifier, communicating with the air purifier via wired communication and with the range hood via wireless communication. The wireless communication method can be, but is not limited to, visible light communication.

[0038] Since visible light communication is a technology that uses the visible light band for data transmission, specifically, the transmitter first modulates the signal to be transmitted onto the visible light emitted by an LED or other light source to obtain an optical signal. Then, the optical signal is transmitted to the receiver through an optical transmission channel. After receiving the optical signal, the receiver converts the optical information into an electrical signal and demodulates the corresponding modulation signal from the electrical signal.

[0039] The transmitting end typically includes an information modulation module, a light source control module, and LED lights. The information modulation module modulates the received signal into an optical signal, which is then transmitted to the light control module. The light control module controls the LED lights' on / off state or intensity based on the received optical signal, causing the LED lights to emit light of varying intensities or flash rapidly. These variations allow the emitted light signals to carry information.

[0040] Optical transmission channels typically refer to air media. Understandably, the light signals emitted by the transmitter can propagate through the air and be received by the receiver from any direction.

[0041] The receiving end typically includes a photodetector and a demodulator. The photodetector receives the optical signal transmitted through the optical transmission channel, detects changes in the optical signal, and transmits the optical signal to the demodulator. The demodulator converts the received optical signal back into an electrical signal and recovers the original signal to be transmitted.

[0042] Based on the above-mentioned visible light communication principle, in order to realize communication between the range hood, the linkage control module, and the air purifier in the embodiments of the present invention, in some embodiments, the following visible light communication system can be constructed on the basis of the range hood, the linkage control module, and the air purifier:

[0043] The aforementioned transmitter is integrated into the range hood, enabling the range hood to modulate relevant signals into optical signals. These optical signals are then used to control the switching or intensity of the light source, causing it to emit light of varying intensities or flash rapidly, thus transmitting information-carrying optical signals. To improve the light source's response sensitivity, reduce its size and energy consumption, and extend its lifespan, white LED lights can be used as the light source. Furthermore, the white LED lights can also serve as the range hood's illumination.

[0044] The aforementioned receiver is integrated into the air purifier, enabling the air purifier to receive optical signals, convert the received optical signals back into electrical signals, and recover the original signal to be transmitted from them.

[0045] Based on the aforementioned visible light communication system, in some embodiments, the linkage control module can be integrated into the range hood. This module receives the operating signal from the range hood and / or the oil fume concentration value detected by oil fume sensors deployed in the area where the range hood is located. It then processes the operating signal and / or oil fume concentration value to obtain a control signal for controlling the air purifier. This control signal is then converted into an optical signal and sent to the air purifier via a transmitter integrated into the range hood. In other embodiments, the linkage control module can be integrated into the air purifier. After the receiver converts the optical signal back into the operating signal and / or oil fume concentration value, it processes the signal to obtain a control signal for controlling the air purifier. In still other embodiments, the linkage control module can be separated from the range hood and air purifier. In this case, another receiver and another transmitter can be integrated into the linkage control module. This allows the linkage control module to convert the optical signal received from the range hood back into an electrical signal, process the electrical signal to obtain a control signal, and then convert the control signal back into an optical signal and send it to the air purifier via the transmitter.

[0046] Therefore, by using a linkage control module and visible light communication, linkage control between the range hood and the air purifier can be achieved.

[0047] Furthermore, to expand the communication range and reliability of visible light, in some embodiments, multiple visible light communication modules can be added to the visible light communication system constructed based on a range hood, a linkage control module, and an air purifier in any embodiment. These visible light communication modules can be deployed in the area where the range hood is located, or distributed among the areas where the range hood and air purifier are located, to expand the effective communication range between the range hood and air purifier, thereby improving the reliability of communication and linkage control. Based on this, the linkage control module can communicate with the range hood and / or air purifier through multiple visible light communication modules. The light source in each visible light communication module can be multiple indoor light sources already deployed in the home environment. Based on this, a receiver and a transmitter for visible light communication can be respectively set in each indoor light source. It is understood that each visible light communication module includes a receiver and a transmitter; each visible light communication module can receive light signals containing information and then emit the light signals through the transmitter.

[0048] In embodiments where the linkage control module communicates with the air purifier via a visible light communication module, to facilitate the linkage control module in obtaining feedback information transmitted by the air purifier to determine whether the air purifier operates according to the control of the linkage control module, in some embodiments, another transmitter can be integrated into the air purifier. This allows the air purifier to also modulate signals related to its own operating state into light signals, and then control the switching or intensity of the light source based on the light signals, so that the light source emits light of different intensities or flashes rapidly, thereby emitting light signals carrying information.

[0049] In some embodiments, to ensure that the light source, which simultaneously serves as a visible light communication light source and an illumination light source, can effectively transmit light signals and provide stable illumination for users, these light sources can all employ white LED light sources. The transmitter will transmit signals by modulating the brightness or color of the white LED light source, instead of using an on / off method to transmit signals, so as not to affect the lighting effect.

[0050] The following combination Figure 2 The home interconnection control method provided in the embodiments of the present invention will be described below. Figure 2 This is a flowchart of a home interconnection control method provided by an embodiment of the present invention, the home interconnection control method comprising:

[0051] In step S100, during the operation of the range hood, the location information of the purifier associated with the range hood is obtained;

[0052] In step S200, based on the location information, it is determined whether the continuous operating time of the purifier at the same location exceeds a first preset duration;

[0053] In step S300, when the purifier runs continuously at the same location for a period of time exceeding the first set time, the oil fume concentration value of the area where the range hood is located is obtained.

[0054] In step S410, when the oil fume concentration value is lower than the set concentration threshold, a control signal is sent to the purifier to reduce the current purification power.

[0055] In step S420, when the oil fume concentration value is not lower than the concentration threshold, a control signal is sent to the purifier to maintain or increase the current purification power.

[0056] In scenarios requiring coordinated control of the air purifier based on the operating status of the range hood, the home interconnection control method provided in this embodiment of the invention can be used. Specifically, after the range hood is started, the linkage control module, which executes the home interconnection control method provided in this embodiment, receives a signal indicating that the range hood has been started. Then, the linkage control module controls the air purifier to start. The purification mode of the air purifier at startup can be determined based on the current operating level of the range hood. For example, if the range hood starts at a low setting, the linkage control module can control the air purifier to start at a low setting; if the range hood starts at a high setting, the linkage control module can control the air purifier to start at a medium setting; if the range hood starts at a high-power setting, the linkage control module can control the air purifier to start at a high setting. Based on this, a mapping relationship between the range hood's power level and the air purifier's power level can be pre-built and stored. In the coordinated control, the linkage control module can obtain the corresponding target air purifier power level from this mapping relationship based on the acquired range hood power level information, and control the air purifier to start at the target air purifier power level.

[0057] During the operation of the range hood after it is started, step S100 can be executed to obtain the location information of the air purifier associated with the range hood. The association between the range hood and the air purifier can be established through device-to-device association methods in related technologies, which will not be elaborated here. The location information of the air purifier can be obtained using any technology in the field of home appliances that enables home appliance positioning. For example, in a visible light communication system embodiment where the air purifier and range hood communicate via visible light communication and include multiple visible light communication modules, the multiple visible light communication modules can utilize a polygon positioning algorithm to calculate the precise location of the air purifier.

[0058] In addition to calculating the precise location of the air purifier, the aforementioned visible light communication modules can also be used to guide the indoor location of the air purifier in a home environment. Based on this, to further improve the communication strength and robustness between the air purifier and the multiple visible light communication modules, and to lay a solid communication foundation for coordinated control, in some embodiments, the home interconnection control method provided by this invention also provides a recommended deployment location scheme for the air purifier. That is, the home interconnection control method provided by this invention may further include:

[0059] In step S010, a polygonal positioning algorithm is used to calculate the recommended location information of the purifier based on the location information of each of the plurality of visible light communication modules; the recommended location information is used to guide the indoor deployment or adjustment of the purifier.

[0060] For step S010, before deploying multiple visible light communication modules, in order to recommend or accurately locate the air purifier's position, the indoor location of each visible light communication module in the home environment is typically recorded during the deployment phase. For example, assuming there are N visible light communication modules, the coordinates corresponding to the indoor locations of these N visible light communication modules are (x1, y1), (x2, y2)...(x... N y N Assuming the required recommended location information for the air purifier is (x, y), then the distances between the N visible light communication modules and the recommended location information (x, y) of the air purifier are as follows:

[0061]

[0062] In the above formulas (1) to (N), D1 represents the distance between the visible light communication module with coordinates (x1, y1) and the position (x, y), and D2 represents the distance between the visible light communication module with coordinates (x2, y2) and the position (x, y). N The coordinates are (x N y N The distance between the visible light communication module and the location (x, y) is given. Before the purifier is deployed, the distance D1 to D2 can be determined based on the effective communication range of the visible light communication module. N Assign values, that is, D1 to D N Given this, based on this, by combining formulas (1) to (N) and using relevant mathematical calculation principles, the value of (x, y) can be calculated. From this, recommended location information (x, y) can be obtained to guide the indoor deployment of the air purifier.

[0063] Alternatively, after the air purifier has been deployed, its real-time location can be obtained using the formulas (1) to (N) above. Unlike the deployment phase, the distance values ​​involved in formulas (1) to (N) are the actual distance values ​​calculated by the visible light communication module based on the signal transmission and reception time when the air purifier is at its current location. This is done by calculating the time difference of signal propagation based on the speed of light and the time difference. In this scenario, after calculating the real-time location of the air purifier, the distance difference between this real-time location and the recommended location information can be determined. If the distance difference is less than the set distance threshold, there is no need to adjust the air purifier's position. If the distance difference is greater than or equal to the distance threshold, the air purifier's position is automatically adjusted, or information prompting the user to adjust the air purifier's position is output.

[0064] In the above-mentioned case of automatically adjusting the position of the purifier, a controllable moving platform can be installed at the bottom of the purifier. By sending a movement control signal to the moving platform, the purifier can be controlled to move to the recommended position indicated by the recommended position information, or to move to a position where the distance between the purifier and the recommended position is less than the aforementioned distance threshold, so as to ensure the communication quality between the purifier and the linkage control module.

[0065] For scenarios where information is output to prompt users to adjust the location of the air purifier, the current location and recommended location of the air purifier can be marked on the home floor plan in the user terminal interface, and text or voice prompts can be output to suggest that the user move the air purifier to the recommended location.

[0066] Therefore, through step S010, the recommended position of the purifier when the communication stability between the purifier and multiple visible light communication modules is good can be calculated. This recommended position can not only guide the placement of the purifier during initial deployment, but also serve as a reference position for the purifier to return to a place with good communication stability when the current position deviates significantly from the recommended position due to movement or other reasons during use. This ensures the communication quality between the purifier and multiple visible light communication modules during both the deployment and application phases, thereby guaranteeing the stability of the linkage control between the purifier and the range hood.

[0067] After obtaining the purifier's location information through any of the above embodiments, step S200 can be executed to determine whether the purifier's continuous operating time at the same location exceeds a first preset duration. To facilitate step S200's determination of the purifier's continuous operating time at the same location, the purifier's location information can be acquired in real-time or periodically and stored through step S100. For periodic acquisition, the periodic duration can be equal to or close to the first preset duration. The first preset duration can be set based on experience or experimentation and is not limited here.

[0068] If step S200 determines that the purifier's continuous operation time at the same location exceeds the first set time, it can be considered that the linkage between the purifier and the range hood has achieved a certain oil fume purification effect. At this time, in order to further ensure the oil fume purification effect, step S300 will be executed to obtain the oil fume concentration value at the range hood by using oil fume sensors installed in the area where the range hood is located.

[0069] After obtaining the oil fume concentration value at the range hood through step S300, the oil fume concentration value can be compared with the set concentration threshold to determine whether the current environmental oil fume concentration has been reduced to a relatively comfortable concentration value perceived by the human body. Based on this, the concentration threshold can be set by the user according to their own needs, or a default value can be used. The default value can be set based on experience or experimentation, and is not limited here.

[0070] When the oil fume concentration value is lower than the above-mentioned concentration threshold, it indicates that the oil fume purification has achieved a good effect. At this time, the purification power of the purifier can be reduced to maintain the purification effect while saving energy. Therefore, step S410 will be executed. The linkage control module will send a control signal to the purifier to reduce the current purification power. For example, if the purifier is currently running at medium speed, it will run at a lower speed after receiving the control signal. Or, if the purifier is currently running at low speed, it can run at an even lower speed or a more energy-saving mode after receiving the control signal, or it can be turned off, as long as the purpose of reducing the current purification power is achieved.

[0071] When the oil fume concentration value is not lower than the aforementioned concentration threshold, it indicates that the oil fume purification has not yet achieved a satisfactory effect. To enhance the purification capacity and improve the purification efficiency, step S420 will be executed. The linkage control module will send a control signal to the purifier to maintain or increase the current purification power. For example, if the purifier is currently running at a high speed, it will continue to run at a high speed or at a higher speed, as long as the purpose of maintaining or increasing the current purification power is achieved. At the same time, the continuous running time of the purifier at the current position will be reset to zero and the timing will restart, and the process will return to step S100 to perform a new round of purification effect judgment.

[0072] If step S200 determines that the purifier's continuous running time at the same location has not exceeded the first set time, no control needs to be applied to the purifier, and the purifier will continue to run at its original speed.

[0073] While the above embodiments can achieve scientific linkage control between the range hood and the air purifier, and effectively improve the oil fume purification effect, in practical applications, the location of the air purifier may change relative to its original position due to various circumstances. This could result in the air purifier being too close or too far from the range hood, thus affecting the oil fume purification effect and efficiency. Therefore, to solve this technical problem, in some embodiments, the home interconnection control method provided by the present invention also provides an air purifier position adjustment scheme for scenarios where the air purifier position changes. That is, the home interconnection control method provided by the present invention may further include:

[0074] In step S500, when it is determined that the current position of the purifier is different from the previous position based on the position information, the distance between the purifier and the range hood, and / or the angle of the air inlet of the purifier relative to the range hood are obtained.

[0075] In step S600, when the distance exceeds a set distance range, a position adjustment command is generated to adjust the position of the purifier; the position adjustment command is used to instruct the distance between the purifier and the range hood to be adjusted to the set distance range; and / or

[0076] In step S700, when the angle exceeds the set angle threshold, an angle adjustment command is generated to adjust the angle of the air inlet of the purifier; the angle adjustment command is used to instruct that the angle of the air inlet of the purifier relative to the range hood be adjusted to not exceed the angle threshold.

[0077] During the operation of the purifier, step S500 can be executed. Based on the position information of the purifier obtained in step S100, it is determined whether the current position of the purifier has changed compared to the previously obtained position. If it has changed, it means that the current position of the purifier is different from the previous position. At this time, the distance between the purifier and the range hood will be obtained. Since the position of the range hood generally does not change during operation, the coordinate position of the range hood in the indoor environment can be recorded when the range hood is deployed indoors. The position of the purifier can be obtained through the above-mentioned records. Therefore, the distance between the purifier and the range hood can be calculated based on the current position of the purifier and the coordinate position of the range hood. In addition, the angle of the air inlet of the purifier relative to the range hood can also be obtained. For example, in the visible light communication method, since the angle of the visible light communication module relative to the range hood is known, and the visible light communication module can determine the direction angle of the purifier by receiving the light signal emitted by the purifier, the light source of the transmitter integrated in the purifier can be set on the side where the air inlet of the purifier is located. Based on the angle of the visible light communication module relative to the range hood and the purifier respectively, the angle of the air inlet of the purifier relative to the range hood can be calculated.

[0078] After obtaining the distance between the purifier and the range hood, and the angle of the purifier's air inlet relative to the range hood in step S500, the distance and angle can be judged separately. That is, it can be judged whether the distance exceeds the set distance range, and whether the angle exceeds the set angle threshold. The distance range and angle threshold can be obtained based on experience or experiments, and are not limited here. For ease of description, it is assumed that the distance range is [first distance threshold, second distance threshold]. Similarly, the first distance threshold and the second distance threshold can also be obtained based on experience or experiments.

[0079] When the distance between the purifier and the range hood is determined to be greater than a second distance threshold, it indicates that the distance between the purifier and the range hood is too far; when the distance between the purifier and the range hood is determined to be less than a first distance threshold, it indicates that the distance between the purifier and the range hood is too close. In both cases, it is considered that the distance between the purifier and the range hood exceeds the aforementioned distance range, which may affect the purification effect. Therefore, step S600 will be executed at this time to generate a position adjustment command for adjusting the purifier. This position adjustment command can be sent to the user terminal to prompt the user to adjust the position of the purifier so that the distance between the purifier and the range hood is adjusted to the aforementioned distance range, that is, so that the distance is greater than or equal to the first distance threshold and less than or equal to the second distance threshold; or, if a controllable moving platform is mounted on the bottom of the purifier, the position adjustment command can be sent to the moving platform to trigger the moving platform to move the purifier so that the distance between the purifier and the range hood is adjusted to the aforementioned distance range. Based on this, the position adjustment command can include the moving direction and moving distance for indicating the movement of the moving platform.

[0080] If it is determined that the distance between the purifier and the range hood does not exceed the above-mentioned distance range, there is no need to generate a position adjustment command, and the purifier can remain in its original position.

[0081] In some embodiments, the actual environment may limit the deployment location of the air purifier and the range hood, preventing them from being too close. Understandably, even when the distance between the air purifier and the range hood is closest, it will still be greater than or equal to the aforementioned first distance threshold. In this case, to simplify the configuration of the aforementioned distance range, the distance range can be adjusted to [0, second distance threshold]. At this time, it is only necessary to consider whether the distance between the air purifier and the range hood is greater than the second distance threshold, without having to judge whether the distance between the air purifier and the range hood is less than the first distance threshold. This can simplify the judgment logic to a certain extent and reduce the occupation of computing resources.

[0082] When it is determined that the angle between the air inlet of the purifier and the range hood exceeds the set angle threshold, it indicates that there is a significant deviation between the purification direction of the purifier and the main flow direction of the fumes, which may result in the fumes not being effectively purified. Therefore, step S700 will be executed at this time to generate an angle adjustment command for adjusting the angle of the air inlet of the purifier. This angle adjustment command can be sent to the purifier, which will control the rotation direction of the fan blades at its air inlet according to the adjustment direction and angle value carried by the angle adjustment command, thereby realizing the adjustment of the air inlet angle of the purifier.

[0083] If it is determined that the angle between the air inlet of the purifier and the range hood does not exceed the set angle threshold, there is no need to generate an angle adjustment command, and the purifier can maintain the current air inlet direction.

[0084] It should be noted that steps S500 to S700 can be modified in several ways. For example, the technical problem of the purifier's effectiveness and efficiency being affected by the distance between it and the range hood being too far or too close can be solved by simply changing the distance between them. In this case, only the distance acquisition step in step S500 and step S600 need to be executed. Alternatively, the purifier's air inlet angle relative to the range hood can be changed to improve the purifier's effectiveness and efficiency from the perspective of the purification direction and the main flow direction of the fumes. In this case, only the angle acquisition step in step S500 and step S700 need to be executed. To achieve better purifier effectiveness and efficiency while solving the above technical problems, the distance between the purifier and the range hood, as well as the angle of the purifier's air inlet relative to the range hood, can be considered simultaneously to adjust the purifier's position. In this case, steps S500 to S700 will be executed, and the order of execution of steps S600 and S700 is not limited.

[0085] Because users typically adjust the range hood's operating level based on the amount of oil fumes generated by the cooking dish, for example, when changing from steaming to stir-frying, if the range hood was initially on a low setting, the user might adjust it to a high setting or stir-fry setting, thus changing the range hood's current operating level. It should be understood that this change in the range hood's operating level is not necessarily triggered by the user; it can also be automatically triggered by the range hood itself based on the oil fume concentration detected by the fume sensor. Therefore, to better match the purifier's purification mode with the range hood's operating mode, and to further improve purification efficiency or reduce energy consumption through their coordinated operation while ensuring effective oil fume purification, in some embodiments of the home interconnection control method provided by this invention, a scheme is also provided to control the purifier's purification mode based on the range hood's operating level. That is, the home interconnection control method provided by this invention may further include:

[0086] In step S810, when a gear signal indicating a change in the current operating gear of the range hood is received, the purification mode of the purifier is determined based on the gear signal, and a control signal is sent to the purifier to trigger it to operate in the purification mode.

[0087] During the operation of the range hood, if the linkage control module receives a gear signal indicating a change in the current working gear of the range hood, it determines the purification mode of the purifier based on the gear signal and sends a control signal to the purifier to trigger it to operate in that purification mode.

[0088] The gear position signal can include the current working gear and the previous working gear of the range hood. When the current working gear is different from the previous working gear, it indicates that the current working gear of the range hood has changed.

[0089] Regarding the above-described implementation method of determining the purifier's purification mode based on the gear position signal, the home interconnection control method provided in this embodiment of the invention proposes the following two implementation schemes:

[0090] The first type:

[0091] The step of determining the purification mode of the purifier based on the gear signal may include:

[0092] Step S81011: When the gear signal indicates that the current working gear of the range hood is higher than the previous working gear, increase the purification power of the purifier to obtain the purification mode of the purifier.

[0093] Step S81012: When the gear signal indicates that the current working gear of the range hood is lower than the previous working gear, reduce the purification power of the purifier to obtain the purification mode of the purifier.

[0094] For step S81011, when the gear position signal indicates that the current working gear of the range hood is higher than the previous working gear, it indicates that the concentration of oil fumes in the indoor environment is currently relatively high or about to increase. Therefore, the current working gear of the range hood is increased. At this time, in order to improve the oil fume purification effect and purification efficiency, the purification power of the purifier is also increased. Thus, the purification mode of the purifier can be determined. For example, since the purification mode of the purifier is controlled by the control signal issued by the linkage control module, the linkage control module can know what the current purification mode of the purifier is. Therefore, when it is determined from the gear position signal analysis that the purification power of the purifier needs to be increased, it is only necessary to control the purifier to operate in a purification mode with a higher purification power than the current purification mode. Thus, the required purification mode can be obtained, and the purification mode can be carried by the control signal, so that the purifier can work in a purification mode with a higher purification power.

[0095] Similarly, for step S81012, when the gear signal indicates that the current working gear of the range hood is lower than the previous working gear, it indicates that the concentration of oil fumes in the indoor environment is currently relatively small or about to decrease. Therefore, the current working gear of the range hood is reduced. At this time, in order to save energy while ensuring the oil fume purification effect, the purification power of the purifier can be reduced. Based on the same principle as obtaining the purification mode of the purifier in step S81011, the purification mode corresponding to the reduction of purification power can also be obtained.

[0096] The second type:

[0097] The step of determining the purification mode of the purifier based on the gear signal may include:

[0098] Step S81020: Obtain the purification mode corresponding to the gear signal from the pre-stored mapping relationship; the mapping relationship stores the purification modes corresponding to different gear signals.

[0099] In the second scheme, the mapping relationship can refer to the mapping relationship between the range hood's gear position and the purifier's gear position as described above. Therefore, in step S81020, as long as the current working gear position is obtained from the gear position signal, the corresponding purifier gear position can be found in the mapping relationship. The purifier's gear position can be understood as the purification mode.

[0100] For air purifiers, their purification effect mainly depends on their filter element. Therefore, to ensure the purification effect of the air purifier on oil fumes or air, it is necessary to monitor the filter element and replace it in a timely manner when necessary. In this regard, in some embodiments, the home interconnection control method provided by the present invention may further include:

[0101] In step S910, while the purifier is continuously operating in the same purification mode for a second set time, the purification rate value of the purifier and the oil fume concentration value of the area where the range hood is located are obtained within the second set time.

[0102] In step S920, when the purification rate value shows a decreasing trend within the second set time period and the oil fume concentration value shows an increasing trend within the second set time period, a prompt message is output to remind the user to replace the filter element of the purifier.

[0103] Through steps S910 and S920, during the operation of the purifier, if the purifier operates continuously in the same purification mode for a second set period of time, and it is found that the purification rate value of the purifier shows a decreasing trend while the oil fume concentration value shows an increasing trend during the second set period of time, it indicates that the filter element of the purifier is saturated and needs to be replaced. Therefore, a prompt message can be played through the display screen, voice broadcaster, or light installed on the purifier, or through the user terminal bound to the purifier. The content of the prompt message may be, but is not limited to, "Please replace the filter element of the purifier." Based on this, in some embodiments, the filter element status value displayed on the purifier's display screen can also be set to the lowest value, for example, 0, to indicate that the filter element can no longer be used and needs to be replaced.

[0104] The second set duration mentioned above can be set based on experience or experimentation, and is not limited here.

[0105] On the other hand, if the purifier's purification rate value changes little or not at all within the second set time period, and the oil fume concentration value also changes little or not at all within the second set time period, it indicates that the oil fume concentration and purification rate remain relatively stable, thus indicating that the filter element is performing well and does not need to be replaced. In this case, the filter element status value displayed on the purifier's screen can remain unchanged.

[0106] In the above, a small fluctuation range can be understood as the difference between the peak and trough of the corresponding value (purification rate value or oil fume concentration value) within the second set time period being less than the set difference threshold. The difference threshold can be set based on experience or experiments and is not limited here.

[0107] On the other hand, if the purification rate of the purifier shows an upward trend within the second set time period, while the oil fume concentration shows a downward trend within the second set time period, it indicates that the filter element may be abnormal, for example, caused by the filter element not being completely dried after cleaning. In order to troubleshoot the filter element and ensure the linkage purification effect of the purifier and the range hood, in some embodiments, the home interconnection control method provided by the present invention may further include:

[0108] In step S930, when the purification rate value shows an upward trend within the second set time period and the oil fume concentration value shows a downward trend within the second set time period, a detection signal for triggering abnormal detection is sent to the purifier.

[0109] In step S940, when it is determined that the filter element of the purifier is abnormal based on the abnormal detection result fed back by the purifier in response to the detection signal, a prompt message is output to remind the user to replace the filter element of the purifier.

[0110] Through steps S930 and S940, when the purifier's purification rate value shows an upward trend within the second set time period, and the oil fume concentration value shows a downward trend within the second set time period, the purifier is promptly triggered to perform an anomaly detection on the filter element. After performing the anomaly detection, the purifier feeds back the detection result to the linkage control module. Upon receiving the anomaly detection result, the linkage control module can determine whether the purifier's filter element is abnormal. If the filter element is indeed abnormal, it outputs a prompt message to replace the purifier's filter element. The output format and expression of this prompt message can be found in the relevant description above and will not be repeated here.

[0111] If the filter element is determined to be normal, in order to reasonably determine the usage status of the filter element, in some embodiments of the present invention, corresponding technical solutions are also provided, that is, the home interconnection control method provided by the embodiments of the present invention may further include:

[0112] In step S950, when the purifier determines that the filter element of the purifier is normal based on the abnormal detection result fed back by the purifier in response to the detection signal, the current filter element status value is updated to the sum of the original filter element status value and the set value.

[0113] In step S960, when the current filter element status value of the filter element reaches a set status threshold, a prompt message is output to remind the user to replace the filter element of the purifier.

[0114] Step S950 updates the filter status value appropriately when the purifier's filter is detected to be normal. Specifically, the current filter status value is updated to the sum of the original filter status value and a set value. This allows the purifier to determine whether to replace the filter in step S960 based on the latest current filter status value. When the current filter status value reaches a set threshold, a prompt message is output to remind the purifier to replace the filter, ensuring timely filter replacement and thus guaranteeing the coordinated purification effect of the purifier and range hood on cooking fumes.

[0115] The output and expression formats of the prompt information are described above and will not be repeated here. The setting value in step S950 and the state threshold in step S960 can be set based on experience or experimentation. For example, the setting value can be configured to 1% and the state threshold can be configured to 80%. This embodiment of the invention does not limit this.
