[0001] The present invention relates to the technical field of linkage control of kitchen electrical appliances, and in particular to a control method and device for a range hood. Background Art

[0002] With the development of Internet of Things and smart home technologies, kitchen appliances have gradually achieved preliminary intelligent linkage. At present, there have emerged on the market devices such as smart range hoods, cooktops, and steam ovens connected through wireless communication technologies such as Wi-Fi (Wireless Fidelity) and Bluetooth, and certain levels of linkage control can be achieved. For example, the common function of "automatically starting the range hood when the cooktop is ignited", that is, when the cooktop detects an ignition signal, it sends a start command to the range hood through a wireless network, and the range hood then starts to operate. Some high-end products can also adjust the air volume gear of the range hood according to the cooking firepower of the cooktop.

[0003] In addition, there is also a simple linkage between a steam oven and a cooktop in the prior art. For example, when the cooktop starts to work, the range hood automatically turns on. These linkage functions are mostly based on one-to-one device communication protocols, implementing a response mechanism of single event triggering single device action.

[0004] Although the prior art has achieved preliminary linkage, when facing complex modern cooking scenarios, there are still defects such as being unable to handle the superposition effect of multiple kitchen electrical appliances working simultaneously; having a single linkage logic and lacking intelligent decision-making; poor user experience and limited reliability.

[0008] In an optional embodiment of this application, the aforementioned multiple kitchen appliances include: a cooktop and a cooking device, wherein the cooking device includes: a steam oven; the linkage signal sent by the cooktop includes a recommended range hood setting mapped based on the cooktop's firepower level, and the linkage signal sent by the cooking device includes a recommended range hood setting mapped based on the cooking device's operating mode and temperature.

[0009] In an optional embodiment of this application, after the above step of determining whether the current state is in a linkage operation state, the method further includes: if the state is not in a linkage operation state, the recommended range hood setting included in the target linkage signal is taken as the final operating setting of the range hood.

[0010] In an optional embodiment of this application, the step of determining the final operating level of the range hood based on the current operating level of the range hood and the recommended operating level of the range hood included in the target linkage signal includes: taking the larger of the current operating level of the range hood and the recommended operating level of the range hood included in the target linkage signal as the final operating level of the range hood.

[0011] In an optional embodiment of this application, after the step of determining whether the current state is in linkage operation, the method further includes: if the state is in linkage operation, obtaining the remaining working time sent by the target kitchen appliance, or determining the remaining working time based on the device identifier of the target kitchen appliance; using the sum of the remaining working time and the preset safety delay as the remaining operating time of the range hood; and controlling the range hood to operate based on the remaining operating time.

[0012] In an optional embodiment of this application, the range hood is equipped with a sensor, including an air quality sensor and / or a temperature and humidity sensor. The method further includes: when a target linkage signal is received from the target kitchen appliance, determining the final operating level of the range hood based on the recommended range hood setting included in the target linkage signal and the data collected by the sensor.

[0013] In an optional embodiment of this application, the above method further includes: acquiring a cooking scene and determining the final operating level of the range hood based on the cooking scene; wherein the cooking scene is sent by the user's terminal device or input by the user through the panel of the range hood, and the terminal device is communicatively connected to the range hood.

[0014] In an optional embodiment of this application, the above method further includes: obtaining the final operating level sent by the cloud; wherein, the status data of multiple kitchen appliances are uploaded to the cloud; the cloud inputs the multiple status data into a pre-trained model and outputs the final operating level.

If it is in a linkage operation state, the final operating speed of the range hood is determined based on the current operating speed and the recommended operating speed included in the target linkage signal. The range hood is then controlled to operate based on the final operating speed. In this method, the range hood can handle scenarios where multiple kitchen appliances are cooking simultaneously, ensuring that the range hood's exhaust capacity meets the highest demand in any combination of multiple kitchen appliances, effectively protecting kitchen air quality.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions 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, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Currently, although existing technologies have achieved preliminary linkage, they still have the following limitations when facing complex modern cooking scenarios: 1. Inability to handle the cumulative effect of multiple kitchen appliances operating simultaneously: When users use a stove (producing fumes) and a steam oven (producing a large amount of steam) at the same time, the fumes and steam in the kitchen will combine, forming a more complex combination of air pollutants. The existing one-to-one linkage mode between range hoods and kitchen appliances can only adjust the range hood according to the status of a single kitchen appliance, and cannot comprehensively judge and respond to this multi-source, superimposed emission demand, resulting in insufficient exhaust volume and deterioration of the kitchen environment.

[0023] 2. Simple linkage logic and lack of intelligent decision-making: Existing technologies typically use fixed command mappings (such as "cooktop on → range hood on medium setting"), lacking the ability to dynamically analyze different combinations of equipment and different working states (such as high flame on the cooktop and high temperature steaming in the oven). When multiple trigger signals arrive simultaneously, the system may experience command conflicts, delayed response, or only execute one command, failing to guarantee optimal ventilation performance in complex cooking scenarios.

[0024] 3. Poor user experience and limited reliability: Due to the above issues, users often need to manually intervene in the range hood settings when cooking with multiple kitchen appliances, losing the convenience of intelligent linkage. Furthermore, the reliability of simple linkage logic decreases in complex scenarios, potentially affecting equipment lifespan and kitchen safety.

[0025] Based on this, embodiments of the present invention provide a control method and device for a range hood, specifically providing a method for adjusting the airflow of a range hood in conjunction with a cooktop and a steam oven. In addition to single-device linkage, a linkage method can be provided that can intelligently respond to complex scenarios where the cooktop and steam oven operate simultaneously or sequentially, ensuring that the range hood's airflow is sufficient to handle the accumulated fumes and steam. A dynamic priority and airflow decision logic can be designed, so that when a linkage request is received from different devices, the range hood can automatically select and execute the operating level and working time that best suits the current kitchen environment. This can improve the intelligence, adaptability, and reliability of multi-device linkage, achieving true "scenario-based" intelligent ventilation without manual user adjustment, thereby significantly improving the user experience. Furthermore, an efficient and stable inter-device communication and collaborative working mechanism can be constructed to ensure the accurate transmission and execution of linkage commands.

[0026] To facilitate understanding of this embodiment, a control method for a range hood disclosed in this embodiment of the invention will first be described in detail.

[0027] Example 1: This invention provides a control method for a range hood, applicable to a range hood that is communicatively connected to multiple kitchen appliances. (See also...) Figure 1 The flowchart shown illustrates a control method for a range hood, which includes the following steps: Step S102: Obtain linkage signals sent by multiple kitchen appliances; wherein, the linkage signals include: device identification and recommended range hood setting.

[0028] In this embodiment, the range hood can be used as the linkage center, and the range hood can establish network connections with multiple kitchen appliances through wireless communication methods such as Wi-Fi and Bluetooth.

[0029] In this embodiment, the range hood can have a built-in control module that can receive linkage signals from multiple kitchen appliances. These linkage signals may include: appliance identifiers (e.g., cooktop, steam oven, etc.) and recommended range hood settings.

[0030] Here, the recommended range hood setting can be understood as the range hood setting required by the kitchen appliance in its own working state. For example, if the stove needs the range hood to be at setting X when it is at setting A, then the linkage signal sent by the stove includes the recommended range hood setting X.

[0031] In addition, the linkage signal can also include the working status signals of each kitchen appliance, such as: switch status, power / temperature level, working time, etc.

[0032] Step S104: When a target linkage signal is received from the target kitchen appliance, determine whether it is currently in linkage operation state.

[0033] When the control module of the range hood receives the target linkage signal sent by the target kitchen appliance, it can first determine whether the range hood is currently in linkage operation state.

[0034] Step S106: If in linkage operation state, determine the final operating level of the range hood based on the current operating level of the range hood and the recommended range hood level included in the target linkage signal.

[0035] If the range hood is currently in linkage operation mode, the current operating level of the range hood can be adjusted according to the recommended range hood level included in the target linkage signal. The adjusted operating level is the final operating level of the range hood.

[0036] This embodiment defines a dynamic decision-making logic: when the range hood receives linkage signals from multiple kitchen appliances simultaneously or sequentially, it does not simply execute the order of arrival. Instead, according to preset rules, it compares the recommended range hood settings corresponding to the two linkage signals (the recommended range hood setting corresponding to the earlier linkage signal is the current operating setting of the range hood, and the recommended range hood setting corresponding to the later linkage signal is the recommended range hood setting included in the target linkage signal) and selects the larger setting as the final operating setting. Simultaneously, the range hood's fan operating time can be intelligently adjusted according to the duration of the equipment's operation to ensure continuous and effective ventilation throughout the complex cooking cycle.

[0037] In this embodiment, the final operating setting can simultaneously meet the airflow requirements of both the target kitchen appliance and the kitchen appliance that is being linked with the range hood.

[0038] Step S108: Control the range hood to operate based on the final operating setting.

[0039] In this embodiment, the range hood can operate based on the final operating setting, thereby ensuring that the range hood's exhaust capacity can meet the highest demand in any scenario involving multiple kitchen appliances.

[0040] This invention provides a method for controlling a range hood, which involves acquiring linkage signals from multiple kitchen appliances. These linkage signals include an appliance identifier and a recommended range hood speed setting. Upon receiving a target linkage signal from a target kitchen appliance, the method determines whether the range hood is currently in a linked operation state. If it is, the method determines the final operating speed setting of the range hood based on its current speed setting and the recommended speed setting included in the target linkage signal. The method then controls the range hood to operate at the final operating speed setting. This approach allows the range hood to handle scenarios where multiple kitchen appliances are cooking simultaneously, ensuring that the range hood's exhaust capacity meets the highest demand in any combination of appliances, effectively protecting kitchen air quality.

[0041] Example 2: This embodiment provides another method for controlling a range hood, which is implemented based on the above embodiment. The focus is on describing the specific implementation of the range hood control method. (See [link]). Figure 2 The flowchart shown illustrates another control method for a range hood, which includes the following steps: Step S202: In advance, the range hood is networked with multiple kitchen appliances via the home wireless network, and the multiple kitchen appliances are monitored via the home wireless network.

[0042] In this embodiment, network initialization and monitoring can be performed in advance: when the range hood and multiple kitchen appliances are powered on, they can automatically form a network through the home wireless network and maintain the connection, broadcasting or monitoring their respective working status in real time.

[0043] Step S204: Obtain the linkage signals sent by multiple kitchen appliances through the home wireless network.

[0044] In this embodiment, the range hood controller can obtain linkage signals sent by multiple kitchen appliances through the home wireless network.

[0045] In some embodiments, the multiple kitchen appliances include: a cooktop and a cooking device, the cooking device including: a steam oven; the linkage signal sent by the cooktop includes a recommended range hood setting mapped based on the cooktop's firepower, and the linkage signal sent by the cooking device includes a recommended range hood setting mapped based on the cooking device's operating mode and temperature.

[0046] This embodiment uses the example of the coordinated control of a range hood, cooktop, and steam oven to illustrate the concept: When the cooktop is ignited, its built-in controller immediately generates a linkage signal. This linkage signal includes at least the device identifier (cooktop) and the recommended range hood setting A1 mapped according to the cooktop's current firepower level, and is sent to the range hood's controller via the network.

[0047] Similarly, when the steam oven starts working (whether it is pure steaming, baking, or a combination of steaming and baking), it will also generate and send a linkage signal. This linkage signal includes at least the device identifier (steam oven) and the recommended range hood setting A2 based on the working mode and temperature mapping of the steam oven.

[0048] The method provided in this embodiment of the invention provides a multi-source linkage signal receiving and processing mechanism: the range hood can simultaneously serve as the linkage control center for the stove and the steam oven, receiving and processing asynchronous or synchronous linkage signals from two independent kitchen appliances, breaking the limitation of traditional one-to-one linkage between the range hood and kitchen appliances, and the range hood can handle the scenario of multiple kitchen appliances cooking together.

[0049] Step S206: When a target linkage signal is received from the target kitchen appliance, determine whether it is currently in linkage operation state.

[0050] In this embodiment, the control module of the range hood can continuously monitor network signals. When it receives a target linkage signal from any target kitchen appliance, the range hood can first check whether it is currently in a linkage operation state.

[0051] In some embodiments, if the range hood is not in a linked operation state, the recommended range hood setting included in the target linkage signal is taken as the final operating setting of the range hood.

[0052] If the range hood is not currently in linkage operation mode, for example, if it is currently off or in standby mode, then the recommended range hood setting included in the target linkage signal can be directly used as the final operating setting of the range hood. Start the range hood and operate at the final operating setting; the airflow of the range hood will meet the airflow requirements of the target kitchen appliance that sent the target linkage signal.

[0053] Step S208: If in linkage operation state, determine the final operating level of the range hood based on the current operating level of the range hood and the recommended range hood level included in the target linkage signal.

[0054] If the range hood is currently in a linked operation mode, it is necessary to ensure that the final operating setting of the range hood can simultaneously meet the airflow requirements of both the target kitchen appliance and the kitchen appliances linked with the range hood.

[0055] In some embodiments, the larger of the current operating level of the range hood and the recommended range hood level included in the target linkage signal can be used as the final operating level of the range hood.

[0056] For example, if the range hood is currently in a linked operation state and the current operating level is B, it is understood that a linkage signal is received from the steam oven. This linkage signal includes a recommended range hood level of A2. In this embodiment, the range hood controller can compare the current operating level B with the above-mentioned range hood level A2 and select the level with the larger value as the final operating level of the range hood, that is, the final operating level = MAX(B, A2).

[0057] The method provided in this embodiment of the invention provides a dynamic airflow decision logic of "taking the larger value first": when multiple linkage signals exist at the same time, the control module of the range hood automatically compares the current operating level of the range hood and the recommended range hood level included in the target linkage signal as the final operating level of the range hood, thereby executing the operating level with the highest airflow demand, while meeting the airflow requirements of the target kitchen appliance and the kitchen appliances that are being linked with the range hood.

[0058] In some embodiments, if in a linked operation state, the remaining working time sent by the target kitchen appliance can be obtained, or the remaining working time can be determined based on the device identifier of the target kitchen appliance; the sum of the remaining working time and the preset safety delay is taken as the remaining operating time of the range hood; and the range hood is controlled to operate based on the remaining operating time.

[0059] This embodiment also allows for time management of the range hood: the range hood can simultaneously acquire or estimate the remaining operating time of the target kitchen appliance. The continuous operating time of the range hood will be based on the remaining operating time of the last kitchen appliance to finish its work, and may include a safety delay (such as 3 minutes) to ensure that the kitchen air is thoroughly purified after all cooking activities are completed.

[0060] This invention provides an intelligent duration management system based on the working time of multiple kitchen appliances: the operating time of the range hood does not depend on a single appliance, but is managed comprehensively based on the last time all interconnected appliances finish their work. This avoids premature termination of the range hood's exhaust or ineffective idling, achieving a balance between energy saving and functional integrity.

[0061] Step S210: Control the range hood to operate based on the final operating setting.

[0062] Step S212: During the operation of the range hood, continuously monitor multiple kitchen appliances via the home wireless network; when the range hood receives the shutdown signals sent by multiple kitchen appliances and the remaining running time of the range hood is reached, turn off the range hood.

[0063] In this embodiment, the range hood can operate based on the final operating level calculated in the aforementioned steps. The range hood's controller can continuously monitor the home wireless network during operation. When all kitchen appliances (cooktop and steam oven) send shutdown signals indicating the end of work or entry into standby mode, and the remaining operating time calculated in the aforementioned steps is reached, the range hood can automatically shut off, completing a full linkage cycle.

[0064] The method provided in this embodiment of the invention offers a scalable control framework for linking range hoods with multiple kitchen appliances. The signal format, decision logic, and communication process proposed in this embodiment constitute a standardized linkage control method, which facilitates the integration of more intelligent kitchen appliances in the future and the construction of a unified intelligent kitchen environment control system. It has good foresight and scalability.

[0065] In some embodiments, the range hood is equipped with sensors, including an air quality sensor and / or a temperature and humidity sensor. When a target linkage signal is received from a target kitchen appliance, the final operating level of the range hood can be determined based on the recommended range hood setting included in the target linkage signal and the data collected by the sensors.

[0066] In this embodiment, the range hood can also make decisions based on sensor fusion: temperature and humidity sensors and / or air quality sensors can be integrated or additionally deployed on the range hood. For example, PM2.5 (inhalable particulate matter) sensors and VOC (volatile organic compounds) sensors.

[0067] When the range hood receives a target linkage signal from the target kitchen appliance, it can not only determine the recommended range hood setting based on the signal, but also read data collected by sensors in real time. The final setting decision is jointly determined by the "recommended range hood setting" and the "sensor data," for example, by using a PID (Proportional-Integral-Derivative) control algorithm to dynamically fine-tune the airflow.

[0068] The method described in this embodiment can respond more accurately to actual changes in kitchen air quality, and is more effective in dealing with sudden oil fumes (such as stir-frying) or steam leaks, with more closed-loop and adaptive control.

[0069] In some embodiments, a cooking scenario can also be acquired, and the final operating level of the range hood can be determined based on the cooking scenario; wherein, the cooking scenario is sent by the user's terminal device or input by the user through the panel of the range hood, and the terminal device is communicatively connected to the range hood.

[0070] In this embodiment, the range hood can also preset its final operating level based on the cooking scenario: users or manufacturers can predefine several cooking scenarios, such as "Chinese stir-fry," "dual-burner stewing + steam oven," and "baking mode." After selecting a scenario via an app or panel, the user can send a unified parameter package to the range hood and various kitchen appliances, which then work together according to the preset program for the scenario. For example, in the "Chinese stir-fry" scenario, the stove defaults to high heat, and the range hood defaults to continuous operation at the highest setting.

[0071] The method described in this embodiment offers a simpler user experience, allowing users to start complex cooking processes with a single click. It avoids delays or fluctuations that may arise from real-time decision-making.

[0072] In some embodiments, the final operating level sent from the cloud can also be obtained; wherein, the status data of multiple kitchen appliances are uploaded to the cloud; the cloud inputs the multiple status data into a pre-trained model and outputs the final operating level.

[0073] In this embodiment, the range hood can also perform AI (Artificial Intelligence) learning based on a cloud platform: the linkage logic between the range hood and various kitchen appliances is deployed on a cloud server. The range hood and various kitchen appliances upload various status data to the cloud, and the cloud uses historical data to train models, learn the user's cooking habits, and generate more personalized airflow control strategies, which are then sent to the range hood for execution.

[0074] The method described in this embodiment has powerful learning and prediction capabilities, and can continuously optimize control strategies to achieve a high degree of personalization and intelligence.

[0075] In summary, the control method for the range hood provided in the embodiments of the present invention has the following main advantages: 1. Efficiently handles complex pollution: By prioritizing the largest demand, the range hood ensures that when the stove and oven are working at the same time, the air volume is always based on the equipment with the higher demand, which can effectively and timely remove the superimposed oil fumes and steam, keeping the kitchen air fresh.

[0076] 2. True intelligence and self-adaptation: The range hood can dynamically respond to various state changes during the cooking process (such as turning up the stove or switching modes of the steam oven), and automatically adjust the air volume. No manual intervention from the user is required throughout the process, achieving a highly intelligent "set and forget" experience.

[0077] 3. Improved reliability of the range hood: Clear decision-making logic avoids command conflicts, ensuring stable and reliable operation of the range hood under multiple event triggers. The time management mechanism prevents the equipment from shutting down prematurely or running ineffectively for extended periods.

[0078] 4. Energy saving and noise balance: When only a single device is working or the demand is low, the range hood operates at a lower setting, which helps to reduce energy consumption and operating noise; it automatically increases the setting only when there is a high demand, achieving a balance between effectiveness and experience.

[0079] 5. Excellent scalability: The decision logic framework has excellent scalability and can be easily connected to more smart kitchen devices (such as air fryers, dishwashers, etc.) in the future to form a more comprehensive smart kitchen environment management system.

[0080] Example 3: Corresponding to the above method embodiments, this embodiment provides a control device for a range hood, characterized in that it is applied to a range hood, and the range hood is communicatively connected to multiple kitchen appliances. See [link to relevant documentation]. Figure 3 The diagram shows a control device for a range hood, which includes: The linkage signal acquisition module 31 is used to acquire linkage signals sent by multiple kitchen appliances; wherein, the linkage signals include: device identification and recommended range hood setting; The linkage operation status judgment module 32 is used to determine whether the current linkage operation status is being determined when a target linkage signal sent by the target kitchen appliance is received. The final operating level determination module 33 is used to determine the final operating level of the range hood based on the current operating level of the range hood and the recommended range hood level included in the target linkage signal if the range hood is in a linkage operation state. The range hood control module 34 is used to control the range hood to operate based on the final operating setting.

[0081] This invention provides a control device for a range hood that acquires linkage signals from multiple kitchen appliances. These linkage signals include an appliance identifier and a recommended range hood speed setting. Upon receiving a target linkage signal from a target kitchen appliance, the device determines whether it is currently in a linkage operation state. If in a linkage operation state, it determines the final operating speed of the range hood based on its current operating speed and the recommended speed setting included in the target linkage signal. The device then controls the range hood to operate based on this final operating speed. This method allows the range hood to handle scenarios where multiple kitchen appliances are cooking simultaneously, ensuring that the range hood's exhaust capacity meets the highest demand in any combination of multiple appliances, effectively protecting kitchen air quality.

[0082] Pre-network the range hood with multiple kitchen appliances via your home Wi-Fi network, see [link / reference]. Figure 4The diagram shows another control device for a range hood, which further includes: a home wireless network monitoring module 35 for monitoring multiple kitchen appliances via a home wireless network; and the aforementioned linkage signal acquisition module for acquiring linkage signals sent by multiple kitchen appliances via the home wireless network. Figure 4 As shown, the control device of the range hood also includes a range hood shutdown module 36, which is used to continuously monitor multiple kitchen appliances through the home wireless network during the operation of the range hood; and to shut down the range hood after receiving shutdown signals from multiple kitchen appliances and the remaining running time of the range hood has elapsed.

[0083] The aforementioned kitchen appliances include: cooktops and cooking equipment. The cooking equipment includes: steam ovens. The linkage signals sent by the cooktops include recommended range hood settings mapped based on the cooktop's firepower. The linkage signals sent by the cooking equipment include recommended range hood settings mapped based on the cooking equipment's operating mode and temperature.

[0084] The aforementioned final operating level determination is also used to determine the recommended range hood level included in the target linkage signal as the final operating level of the range hood if it is not in a linkage operation state.

[0085] The aforementioned final operating level determination is used to determine the larger of the current operating level of the range hood and the recommended range hood level included in the target linkage signal as the final operating level of the range hood.

[0086] The aforementioned range hood control module is also used to, if in a linked operation state, obtain the remaining working time sent by the target kitchen appliance, or determine the remaining working time based on the device identifier of the target kitchen appliance; use the sum of the remaining working time and the preset safety delay as the remaining running time of the range hood; and control the range hood to operate based on the remaining running time.

[0087] The aforementioned range hood is equipped with sensors, including an air quality sensor and / or a temperature and humidity sensor. The device also includes a sensor processing module, which, when receiving a target linkage signal from a target kitchen appliance, determines the final operating level of the range hood based on the recommended range hood setting included in the target linkage signal and the data collected by the sensors.

[0088] The aforementioned device also includes: a cooking scene processing module, used to acquire cooking scenes and determine the final operating level of the range hood based on the cooking scenes; wherein, the cooking scene is sent by the user's terminal device or input by the user through the panel of the range hood, and the terminal device is communicatively connected to the range hood.

[0089] The aforementioned device also includes: a cloud processing module for acquiring the final operating level sent from the cloud; wherein, the status data of multiple kitchen appliances are uploaded to the cloud; the cloud inputs the multiple status data into a pre-trained model and outputs the final operating level.

[0090] Those skilled in the art will understand that, for the sake of convenience and brevity, the specific working process of the control platform of the range hood described above can be referred to the corresponding process in the embodiments of the control method of the range hood mentioned above, and will not be repeated here.
