[0039] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0040] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0041] This disclosure provides a control device for a stove. The control device is applied to the stove and specifically controls the stove's heat output. The control device can be integrated with the stove body or located outside the stove body to independently control the stove's heat output. When the control device is located outside the stove body, it can communicate with the stove via wired connection or wired connection to send corresponding control signals to the stove.

[0042] Regarding the control device provided in this embodiment, see [link to relevant documentation]. Figure 1 The control device specifically includes a trigger sensing component 11, a processing component 12, and a fire control component 13. The processing component 12 is electrically connected to both the trigger sensing component 11 and the fire control component 13.

[0043] Specifically, the trigger sensing component 11 is disposed on the surface of the stovetop, which may be the edge of the stovetop or on the stovetop's interactive panel. For example, the type of trigger sensing component 11 includes, but is not limited to, an infrared sensor or a micro switch.

[0044] The trigger sensor component 11 can be used to monitor user activities in the kitchen area. The trigger sensor component 11 has a built-in time system. When a user moves within the monitoring range of the trigger sensor component, the trigger sensor component 11 will be triggered, and the historical time nodes of the user's activities will be collected and sent to the processing component 12.

[0045] Processing component 12 is used to determine a preset time node based on historical time nodes. For users, their daily activities, in the long run, exhibit consistency and regularity in the timing of their activities. In other words, historical time nodes can be used to determine the user's activity patterns, thereby determining the preset time node.

[0046] For example, if the historical time point is that the user performs cooking operations around 11 o'clock on the weekend, the preset time point can be determined to be 11 o'clock on the weekend.

[0047] After determining the preset time node, the processing component 12 sends a target control signal to the firepower control component 13 at the preset time node. The target control signal can be a signal that controls the firepower of the stove, specifically including signals that control the firepower level and duration of the stove. The target control signal can be determined according to the user's preset settings or based on historical control signals, and is not specifically limited here.

[0048] In addition, in most cases, the preset time point can be converted into a historical time point after the user has completed the operation.

[0049] The fire control component 13 receives signals to control the firepower of the stove according to a target control signal. The fire control component 13 can be a motor, but is not limited to this; it can be selected according to the actual situation. Taking a motor as an example, the motor controls the firepower by adjusting the air intake. Specifically, the motor controls the gas valve inside the stove through a mechanical device (such as a gear or linkage). When firepower control is needed, the motor rotates to increase or decrease the valve opening, changing the flow of gas into the burner, thereby changing the firepower.

[0050] In one embodiment, the processing component 12 may be a PC (Personal Computer), a microcontroller, a server, etc. The processing component 12 is further described below:

[0051] See Figure 2 The processing component 12 also includes a determining unit 121, an acquiring unit 122, and a storage unit 123. The determining unit 121 is electrically connected to the trigger sensing component 11 and the storage unit 123, respectively, and the acquiring unit 122 is electrically connected to the determining unit 121 and the fire control component 13, respectively.

[0052] Specifically, storage unit 123 stores historical control signals that correspond one-to-one with historical time nodes. These historical control signals can be signals generated when the user operates the stove at the corresponding historical time node. Generally, there is a certain regularity between historical control signals and historical time nodes, and corresponding historical control signals to historical time nodes can better reflect the user's cooking needs and preferences at different time nodes. For example, if the historical control signal represents simmering over low heat, and the corresponding historical time node is 7:00 AM, this indicates that the user prefers to perform simmering over low heat around 7:00 AM. Therefore, a preset time node can be set to 7:00 AM, and the corresponding target control signal is the control signal representing simmering over low heat.

[0053] Based on the above statement, the time nodes when users perform activities are consistent and regular, and the determining unit 121 is used to determine the preset time node corresponding to the historical time node.

[0054] Generally speaking, the activities performed by the user at the preset time node corresponding to the historical time node are the same. Therefore, the acquisition unit 122 is used to acquire the historical control signal from the storage unit 123 at the preset time node according to the historical time node corresponding to the preset time node, and use the historical control signal as the target control signal of the preset time node.

[0055] In addition, in most cases, the target control signal can be converted into a historical control signal after the user operation is completed.

[0056] In this embodiment, the processing component 12 can acquire and store historical time points and historical control signals of user operations. On the one hand, by determining preset time points based on historical time points, the regularity of user operations in terms of time can be determined; on the other hand, by determining target control signals based on historical control signals, the regularity of user operations in specific cooking operations can be determined. Based on the linkage between time points and control signals, the user's cooking needs and preferences at different time points can be predicted, and the cooking mode can be automatically optimized according to user habits, thereby improving user experience, increasing cooking efficiency, and reducing manual adjustments by the user.

[0057] In one specific implementation, the determination of the preset time node corresponding to the historical time node by the determining unit 121 is explained as follows:

[0058] The processing component 12 also includes a model unit. The model unit is electrically connected to the determination unit.

[0059] The model unit is used to load the time model, which is trained based on historical time nodes; the time model is used to determine preset time nodes. The determination unit 121 is used to determine the preset time node corresponding to the historical time node through the model unit.

[0060] The initial model for the time model can include, but is not limited to, machine learning models, time algorithms, and deep learning models.

[0061] In one embodiment, see Figure 3 The control device also includes an environmental sensing component 14. The environmental sensing component 14 is electrically connected to the processing component 12.

[0062] The ambient sensing component 14 is disposed on the countertop of the cooktop, specifically on the edge of the cooktop or on the interactive panel of the cooktop. For example, the types of ambient sensing component 14 include, but are not limited to, ambient light sensors and temperature sensors.

[0063] The environmental sensing component 14 is used to collect historical environmental information about the user's past activities. This historical environmental information includes, but is not limited to, ambient light intensity and temperature information. The environmental sensing component 14 sends the historical environmental information to the processing component 12. Each historical environmental information corresponds one-to-one with a historical time point.

[0064] The processing component 12 is also used to adjust the preset time nodes based on historical environmental information.

[0065] Taking ambient light intensity as an example, this information reflects changes in kitchen lighting. Based on the changing patterns of daylight hours in winter and summer, we know that ambient light intensity differs at the same time in winter and summer. This translates to a difference in user activity: users might cook slightly later in the morning in winter than in the morning in summer. Therefore, using the same preset time as in summer would be inaccurate. Thus, this embodiment incorporates historical environmental information to adjust the preset time. This adjustment can be achieved through machine learning models or algorithms to obtain time information that better reflects user activity patterns, thereby further meeting user needs.

[0066] In one embodiment, the control device further includes an interaction component electrically connected to the processing component 12.

[0067] The interactive component is used to generate operation instructions based on user operations, and the processing component 12 is used to generate target control signals based on the operation instructions.

[0068] The operational commands include, but are not limited to, commands to increase or decrease firepower, and commands to increase or decrease firepower duration. Target control signals are generated based on the corresponding operational commands to control the firepower.

[0069] In this embodiment, controlling the target control signal according to the user's operation instructions can improve the temperature control accuracy of the stove and further meet the user's needs.

[0070] In one specific implementation, the interactive component includes an interactive panel, which is mounted on the countertop of the stove. Users can directly generate operation commands on the interactive panel during cooking.

[0071] In one specific implementation, the interactive component includes a first communication unit, which is communicatively connected to a second communication unit of an external device.

[0072] External devices include, but are not limited to, mobile phones and computers. Communication connection methods include, but are not limited to, Wi-Fi (Wireless Fidelity), Zigbee (a low-power, low-data-rate, short-range wireless communication technology), or Bluetooth. Specifically, the external device is loaded with an application that coordinates the second communication unit with the first communication unit. The user generates operation commands through the application, which are then sent to the control device via the second and first communication units. The control device generates target control signals based on the operation commands to control the firepower.

[0073] For example, users can set the heat duration and heat level in the application, and they can also set cooking preferences in the application. Cooking preferences include, but are not limited to, the doneness of the food. The processing component 12 can also adjust the target control information according to the cooking preferences.

[0074] In one specific implementation, in addition to the aforementioned external devices such as mobile phones, the first communication unit of the interactive component can also communicate with the third communication unit of the kitchen equipment.

[0075] Kitchen equipment includes, but is not limited to, refrigerators, storage cabinets, and cookware. Communication connection methods include, but are not limited to, Wi-Fi, Zigbee, or Bluetooth. The kitchen equipment can collect information about the ingredients stored within it and transmit this information to the control device via a third communication unit and a first communication unit. The processing component 12 in the control device can also adjust the target control signal based on the ingredient information.

[0076] For example, the refrigerator can send information about the food in the refrigerator to the control device, and the processing component 12 can obtain cooking suggestions corresponding to the food information from the Internet and adjust the target control information according to the cooking suggestions.

[0077] In one embodiment, the fire control component includes a motor.

[0078] The motor is electrically connected to the gas valve and the processing unit of the stove. The motor is used to control the opening degree of the gas valve according to the target control signal.

[0079] Specifically, the motor controls the gas valve inside the stove through a mechanical device (such as a gear or linkage). When the firepower needs to be controlled, the motor rotates to increase or decrease the opening of the valve, changing the flow of gas into the burner, thereby changing the firepower.

[0080] In one specific implementation, the motor can also automatically control the opening degree according to the temperature of the pot to avoid the pot temperature from getting too high, causing dry burning, scorching, or other problems.

[0081] Specifically, the control device also includes a temperature sensor, which is electrically connected to the motor.

[0082] A temperature sensor is placed on the cooking pot facing the stovetop. The temperature sensor is used to collect the cooking temperature of the cooking pot, and the motor is also used to control the opening of the gas valve according to the cooking temperature.

[0083] An exemplary embodiment of this disclosure provides a stove, see [link to example]. Figure 4 The stove includes a control device 10 and a main body 20 as described in the above embodiment.

[0084] The main body 20 of the stove is equipped with at least one gas stove and at least one motor. The gas stove outputs heat through a gas valve. The motor controls the gas valve inside the stove through a mechanical device (such as a gear or linkage). When it is necessary to control the heat, the motor rotates to increase or decrease the opening of the valve, thereby changing the flow of gas into the burner and thus changing the heat.

[0085] In one embodiment, the gas stove mounted on the stove body 20 employs premixed combustion technology.

[0086] Premixed combustion technology is a combustion method in which fuel and air are fully mixed before entering the burner, ensuring a more efficient, uniform, and clean combustion process, reducing pollutant emissions, and improving combustion efficiency.

[0087] In premixed combustion, fuel (such as natural gas) and air are mixed in a specific ratio before entering the combustion zone. When this mixture enters the burner and is ignited, the fuel reacts fully with the air, achieving more efficient and stable combustion and reducing the generation of unburned fuel and pollutants (such as carbon monoxide and nitrogen oxides).

[0088] Specifically, a gas stove includes the following components: fuel supply assembly, air supply assembly, mixer, ignition device, burner, and exhaust assembly.

[0089] The mixer is connected to both the fuel supply assembly and the air supply assembly. The burner is connected to the mixer. The ignition device and the exhaust assembly are located within the space where the burner is located. The space where the burner is located can be a closed space.

[0090] The purpose of the above components is explained below:

[0091] The fuel supply assembly is responsible for delivering fuel (such as natural gas, propane, etc.) to the mixer. The fuel supply needs to be precisely controlled to ensure an appropriate mixing ratio with air.

[0092] The air supply component provides an appropriate amount of air into the mixer, typically supplied by a fan or blower to ensure thorough mixing of air and fuel.

[0093] The mixer is the core of premixed combustion, where fuel and air are mixed in a preset ratio to ensure an appropriate air excess coefficient during combustion.

[0094] An ignition device is used to ignite a mixture of air and fuel. Common ignition methods include spark ignition and high-temperature ignition elements.

[0095] In a burner, premixed gases are ignited. Because premixed combustion provides more uniform combustion, burner design typically aims to ensure stable and uniform combustion.

[0096] Exhaust assembly is used to discharge the waste gases generated during combustion. Premixed combustion results in fewer harmful substances in the exhaust gases due to more complete combustion, but the exhaust gases still need to be safely discharged through the exhaust system.

[0097] In one embodiment, the gas stove mounted on the stove body 20 adopts a fully enclosed combustion chamber.

[0098] A fully enclosed combustion chamber is a combustion device that completely isolates the combustion process from the outside air, aiming to improve combustion efficiency, reduce heat loss, and enhance safety.

[0099] In a fully enclosed combustion chamber, the air required for combustion is introduced from the outside or through specific channels within the closed system, and the exhaust gases produced are discharged through a sealed exhaust pipe. The entire combustion process is isolated from outside air, preventing indoor air from participating in the combustion. This design ensures more stable, safe, and efficient combustion.

[0100] Specifically, a gas stove includes the following components: combustion chamber shell, air intake assembly, exhaust assembly, and burner.

[0101] The combustion chamber shell isolates the combustion chamber from the outside world. The intake and exhaust components enter the combustion chamber through the combustion chamber shell, and the burner is located inside the combustion chamber.

[0102] The purpose of the above components is explained below:

[0103] The combustion chamber shell, a sealed enclosure that isolates the combustion process from the external environment, is typically made of high-temperature resistant materials.

[0104] The air intake assembly draws air from the outside or through specific vents via a dedicated channel to ensure a sufficient supply of oxygen during combustion.

[0105] The exhaust system ensures that the exhaust gases produced during combustion are discharged through a sealed exhaust pipe, preventing indoor air pollution.

[0106] A burner is used to ignite fuel, which mixes with supplied air and burns to provide heat.

[0107] The premixed combustion technology and fully enclosed combustion chamber provided in this embodiment can reduce energy consumption and optimize cooking results compared to traditional combustion methods.
