Description

Technical Field

[0001] This invention relates to the field of kitchen appliance technology, and in particular to a smart cookware, stove, and range hood. Background Technology

[0002] With the fast pace of life, people are pursuing easier and more convenient cooking methods. However, various problems still arise when using integrated stoves: 1. The range hood works well when the airflow is high, but it is noisy; the airflow is low and the noise is acceptable, but the smoke extraction effect is not ideal; 2. Because there is no water boiling status reminder, the cook can only wait by the integrated stove, otherwise there will be overflowing or dry burning.

[0003] Currently, the existing range hood and stove linkage generally works as follows: after the stove is ignited, the range hood automatically operates according to the airflow setting received by the wireless module; after the stove is turned off, the range hood operates according to the delayed shutdown command received by the wireless module.

[0004] However, the existing range hood and cooktop linkage methods only involve the range hood and cooktop, and cannot intelligently select the range hood airflow and cooktop setting based on the amount of oil fumes generated by the cookware in different scenarios, resulting in a generally poor user experience. Summary of the Invention

When the lid is attached to the pot body, the first contact point and the second contact point abut against each other, the control module of the pot receives the signal from the first temperature sensor, and determines that the lid is in the "lid in position" state. When the lid is not attached to the pot body, the first contact point and the second contact point are separated, the control module of the pot does not receive the signal from the first temperature sensor, and determines that the lid is in the "lid removed" state.

[0011] In an optional embodiment of this application, the stove is equipped with a pot detection probe; when the pot is placed on the stove, the pot detection probe is triggered, and the stove's control module determines the pot status as "pot placed" based on the signal from the pot detection probe, and the stove's control module sends the pot status to the pot's control module; when the pot is not placed on the stove, the pot detection probe is not triggered, and the stove's control module determines the pot status as "pot not placed" based on the signal from the pot detection probe, and the stove's control module sends the pot status to the pot's control module.

[0027] 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.

[0028] With the fast pace of life, people are pursuing easier and more convenient cooking methods. However, various problems still arise when using integrated stoves: 1. The range hood works well when the airflow is high, but it is noisy; the airflow is low and the noise is acceptable, but the smoke extraction effect is not ideal; 2. Because there is no water boiling status reminder, the cook can only wait by the integrated stove, otherwise there will be overflowing or dry burning.

[0029] Currently, the existing range hood and stove linkage generally works as follows: after the stove is ignited, the range hood automatically operates according to the airflow setting received by the wireless module; after the stove is turned off, the range hood operates according to the delayed shutdown command received by the wireless module.

[0030] However, the existing range hood and cooktop linkage methods only involve the range hood and cooktop, and cannot intelligently select the range hood airflow and cooktop setting based on the amount of oil fumes generated by the cookware in different scenarios, resulting in a generally poor user experience.

[0031] Based on this, embodiments of the present invention provide a smart cookware, a cooktop, and a range hood, specifically providing a smart cookware. The smart cookware in this embodiment is equipped with a rechargeable battery, an NTC (Negative Temperature Coefficient) detection probe installed on the bottom of the pot, an NTC temperature detection probe installed on the top inner side of the lid, and a wireless Bluetooth module. It calculates the airflow of the range hood and the heat output of the cooktop based on the cooking scenario and notifies the range hood and cooktop via the Bluetooth module.

[0032] This embodiment can also intelligently adjust the range hood's airflow based on the cooking scenario; determine if the water in the pot is boiling based on the pot lid and bottom temperatures, and remind the user; reduce the stove's heat when the water in the pot is boiling to reduce or prevent overflow. This improves the smoke extraction effect while reducing the range hood's power consumption; it also determines and reminds the user that the water in the pot is boiling, enhancing the level of intelligent cooking; and it anticipates overflow in advance, reducing or preventing overflow.

[0033] This embodiment aims to provide users with a more relaxed and convenient cooking method: intelligently select the range hood airflow according to the amount of oil fumes generated by the cookware in different scenarios, intelligently determine the scenario of water boiling and promptly remind the user, and at the same time notify the stove to reduce the heat to reduce or prevent overflow.

[0034] To facilitate understanding of this embodiment, a detailed description of the linkage control method for cookware, stove, and range hood disclosed in this embodiment of the invention will be provided first.

[0035] Example 1:

[0036] This invention provides a smart cookware, comprising: a pot body and a pot lid; a first temperature sensor is disposed on the pot lid, a second temperature sensor is disposed on the pot body, and a positioning detection device is disposed on the pot lid and / or the pot body, the positioning detection device being used to detect the closed state of the pot lid on the pot body; the smart cookware also comprises a communication module and a control module; the communication module is used to establish a communication connection with a stove and / or a range hood, and the control module is used to control the communication module to send corresponding instruction information to the stove and / or the range hood according to the first temperature information, the second temperature information, and the positioning detection information; wherein, the first temperature information is acquired by the first temperature sensor, the second temperature information is acquired by the second temperature sensor, and the positioning detection information is acquired by the positioning detection device.

[0037] First, let's introduce the smart cookware in this embodiment. (See also...) Figure 1 The diagram shows a smart cookware. In this embodiment, a first temperature sensor 5 (which can be a first temperature detection probe) can be installed on the top inner side of the cookware lid. The first temperature information collected by the probe can be used to detect the real-time temperature inside the cookware cavity and whether the lid is properly closed.

[0038] In some embodiments, the edge of the lid is provided with a first contact point, and the edge of the pot body is provided with a second contact point; when the lid is attached to the pot body, the first contact point and the second contact point abut against each other, the control module of the pot receives the signal from the first temperature sensor, and determines that the lid is in the lid position state; when the lid is not attached to the pot body, the first contact point and the second contact point are separated, the control module of the pot does not receive the signal from the first temperature sensor, and determines that the lid is in the lid removed state.

[0039] like Figure 1 As shown, when the lid and pot body are in place, the first contact 4 and the second contact 3 connect, and the first temperature detection probe is connected to the control module. The control module can then acquire the real-time temperature inside the pot cavity (i.e., the first temperature information). When the lid is removed, the first contact 4 and the second contact 3 disconnect, and the first temperature detection probe disconnects from the control module. The control module can determine that the lid has been removed by detecting the disconnection signal of the first temperature detection probe. In addition, a second temperature sensor 6 (which can be a second temperature detection probe) is also installed at the bottom of the pot in this embodiment. This second temperature sensor is connected to the control module, and the collected second temperature information can be used to detect the bottom temperature of the pot in real time, which is used for anti-overflow, anti-sticking, and anti-dry-burning functions.

[0040] In some embodiments, the cooktop is equipped with a pot detection probe; when the pot is placed on the cooktop, the pot detection probe is triggered, and the cooktop's control module determines the pot status as "pot placed" based on the signal from the pot detection probe, and sends the pot status to the pot's control module; when the pot is not placed on the cooktop, the pot detection probe is not triggered, and the cooktop's control module determines the pot status as "pot not placed" based on the signal from the pot detection probe, and sends the pot status to the pot's control module.

[0041] like Figure 1 As shown, the first contact 4 and the second contact 3 can both be set on the handle of the smart cookware, so as to facilitate the determination of whether the lid has been removed.

[0042] See also Figure 2 The diagram shows a stove with a knob 1 and a pot detection probe 2. In this embodiment, the cookware can work with a stove that has pot detection and automatic heat adjustment functions to achieve range hood airflow and stove heat adjustment. When the cookware is placed on the stove, the pot detection probe 2 is triggered, and the stove control module receives a low-level signal to determine that a cookware is on the stove. When the cookware is removed, the pot detection probe 2 is released, and the stove control module receives a high-level signal to determine that no cookware is on the stove. The stove can also be equipped with a communication module (e.g., a wireless Bluetooth module) to send the cookware status, heat level, and ignition information to the cookware in real time. The cookware will send the required heat level to the stove, and it will also send the range hood airflow information to the range hood.

[0043] In this embodiment, during the cooking process, the cookware control module can determine different scenarios in real time based on the first temperature information (used to characterize the temperature of the pot lid), the second temperature information (used to characterize the temperature of the bottom of the pot), and the position detection information (used to characterize the state of the pot lid), and adjust the range hood airflow and the stove setting according to the different scenarios.

[0044] In some embodiments, the smart cookware sends instruction information to the range hood or the cooktop via a communication module; or, the smart cookware sends instruction information to the cooktop via a communication module, and the cooktop then sends the instruction information to the range hood; or, the smart cookware sends instruction information to the range hood via a communication module, and the range hood then sends the instruction information to the cooktop.

[0045] In this embodiment, communication modules can be installed in the smart cookware, range hood, and cooktop, allowing them to communicate with each other. After determining the command information from the range hood or cooktop, the control module of the smart cookware can directly send the command to the communication module of the range hood or cooktop, or the range hood's communication module can forward the cooktop's command information to its communication module, and vice versa.

[0046] In some embodiments, the smart cookware is used to determine whether the cookware is in an unloaded state or a loaded state based on a positioning detection device installed on the cookware body; if the cookware is in an unloaded state, the smart cookware is used to determine the range hood's setting as the first setting; if the cookware is in a loaded state, the smart cookware is used to determine the range hood's setting based on second temperature information and a positioning detection device installed on the lid; the smart cookware is used to use the range hood's setting as instruction information for the range hood.

[0047] See also Figure 3 The diagram shows how the range hood is set to a specific setting after the stove is ignited. When the stove is ignited or burning, if the cookware is not in use, the cookware sends the first setting (i.e., setting 1, corresponding to low airflow L1) as a command to the range hood.

[0048] like Figure 3 As shown, if the cookware is in the "cookware placed" state and the second temperature information is less than the first temperature threshold TS1 (which can be 80℃), it is determined that the stove has just been turned on for cooking. The cookware sends the first setting (i.e., setting 1, corresponding to low airflow L1) as the instruction information of the range hood to the range hood.

[0049] like Figure 3As shown, if the cookware is in the "cookware placed" state, and the second temperature information is greater than or equal to the first temperature threshold TS1 (which can be 80℃) and less than the second temperature threshold TS2 (which can be 150℃), it is determined that the second temperature information is slightly high and a small amount of oil smoke is generated. The cookware sends the second setting (i.e., setting 2, corresponding to medium air volume L2) as the instruction information of the range hood to the range hood.

[0050] like Figure 3 As shown, if the pot is in the "pot placed" state, and the second temperature information is greater than or equal to the second temperature threshold TS2 (which can be 150℃) and less than the third temperature threshold TS3 (which can be 200℃), it is determined to be a scenario where the bottom of the pot is hot and a large amount of oil fumes are generated. In this case, the range hood setting needs to be determined by the positioning detection device set on the pot lid.

[0051] like Figure 3 As shown, if the positioning detection information detected by the positioning detection device on the pot lid indicates that the pot lid is in the positioning state, it is determined that the oil fumes are emitted in a relatively small manner. At this time, the cookware sends the third level (i.e., level 3, corresponding to strong air volume L3) as the instruction information to the range hood.

[0052] like Figure 3 As shown, if the positioning detection information detected by the positioning detection device on the pot lid indicates that the pot lid is in the position of being removed, it is determined that the pot lid has been removed and a lot of oil fumes are emitted. At this time, the cookware sends the fourth level (i.e., level 4, corresponding to the super strong air volume L4) as the instruction information to the range hood.

[0053] Furthermore, this embodiment can also perform dry-burning detection. For example... Figure 3 As shown, if the second temperature information is greater than or equal to the third temperature threshold TS3 (which can be 200℃) and less than the fourth temperature threshold TS4 (i.e., dry burning protection temperature, which can be 250℃), it is judged as a scenario with a lot of oil fumes. At this time, the cookware sends the fourth level (i.e., level 4, corresponding to super strong air volume L4) as the instruction information of the range hood to the range hood.

[0054] like Figure 3 As shown, if the second temperature information is greater than or equal to the fourth temperature threshold TS4 (i.e., the dry-burn protection temperature, which can be 250℃), it is determined to be a dry-burn scenario of the bottom of the pot. At this time, the pot sends the fourth level (i.e., level 4, corresponding to the super strong air volume L4) as the instruction information of the range hood to the range hood. The pot also needs to send a fire-off instruction to the stove as the instruction information of the stove, and the stove will turn off.

[0055] See also Figure 4The diagram illustrates how the range hood setting is determined after the stove is turned off. When the stove is turned off, if the cookware is in the "no cookware" state, the cookware sends a command to the range hood to shut off the fan speed, and the range hood turns off. If the cookware is in the "cookware placed" state, the range hood setting needs to be determined based on the position of the cookware lid.

[0056] like Figure 4 As shown, if the lid positioning information indicates that the lid is in the correct position, the cookware sends the second setting (i.e., setting 2, corresponding to medium airflow L2) as a command to the range hood. The cookware then continuously monitors the temperature of the bottom of the pot and adjusts the range hood setting based on the second temperature information.

[0057] like Figure 4 As shown, if the second temperature information is less than the second temperature threshold TS2 (which can be 150℃), the cookware sends the first setting (i.e., setting 1, corresponding to low airflow L1) to the range hood as a command. Until the second temperature information is less than the first temperature threshold TS1 (which can be 80℃), the cookware sends a command to the range hood to turn off the airflow, and the range hood shuts off.

[0058] like Figure 4 As shown, if the positioning detection information indicates that the lid is in the open state, the cookware sends the fourth setting (i.e., setting 4, corresponding to the super strong airflow L4) as a command to the range hood. The cookware then continuously monitors the second temperature information and adjusts the range hood setting based on the second temperature information.

[0059] like Figure 4 As shown, if the second temperature information is less than the second temperature threshold TS2 (which can be 150℃), the cookware sends the third setting (i.e., setting 3, corresponding to strong airflow L3) as a command to the range hood. This continues until the second temperature information is less than the first temperature threshold TS1 (which can be 80℃). At this point, the cookware sends a command to the range hood to turn off the airflow, and the range hood shuts off.

[0060] This invention can intelligently adjust the range hood's airflow and the cooktop's setting based on the cooking scenario. It comprehensively judges the amount of oil fumes generated by the cookware based on information such as the pot's bottom temperature, lid temperature, and whether the lid is properly positioned, and adjusts the range hood's airflow and cooktop setting accordingly. When there is a lot of oil fumes, the range hood's airflow can be increased; when there is a little oil fumes, the airflow can be decreased, ensuring effective fume extraction while reducing range hood noise. It also allows for the selection of appropriate cooktop heat.

[0061] This invention provides a smart cookware. A positioning detection device on the lid and / or body of the smart cookware detects the lid's closing status on the pot body. The control module of the smart cookware sends corresponding instructions to the cooktop and / or range hood based on first temperature information collected by a first temperature sensor on the lid, second temperature information collected by a second temperature sensor on the pot body, and positioning detection information collected by the positioning detection device. This method intelligently selects the range hood's airflow and cooktop setting based on the amount of oil fumes generated by the cookware in different scenarios. This ensures effective fume extraction while reducing range hood noise and allows for selection of appropriate cooktop heat, thereby improving the user experience.

[0062] Example 2:

[0063] This embodiment provides another method for the coordinated control of cookware, stove, and range hood. This method is implemented based on the above embodiment, and focuses on describing the intelligent judgment of water boiling in the cookware and the way to reduce the firepower of the stove when the water boils.

[0064] In some embodiments, if the cookware is in a placed state, the smart cookware determines the lid state as either in place or removed based on the positioning detection device on the lid; if the lid is in place, the smart cookware determines whether the water in the cookware is boiling based on first and second temperature information; if the lid is removed, the smart cookware determines whether the water in the cookware is boiling based on the second temperature information.

[0065] During the cooking process, this embodiment can first determine the state of the pot lid as either in place or removed based on the positioning detection device on the pot lid, and then determine that the water in the pot is boiling based on the first temperature information representing the temperature of the pot lid and the second temperature information representing the temperature of the bottom of the pot, and remind the user.

[0066] See also Figure 5 The diagram illustrates a method for determining when water in a pot is boiling. When the lid is placed on the pot and the pot is placed on the stove (i.e., the pot is in the "pot placed" state and the lid is in the "lid in place" state), the second temperature information Tb and the first temperature information Tp are recorded in real time. Because there is water in the pot above the second temperature sensor at the bottom of the pot, and the pot below is heated by the fire, the second temperature information Tb will remain relatively stable after rising to a certain level, and the temperature will be slightly higher than the water temperature. As the water in the pot is heated, the cavity gradually fills with steam, and because the boiling point of water is different under different air pressures, the first temperature information Tp of the lid will remain relatively stable within a certain temperature range after rising to a certain level.

[0067] like Figure 5As shown, when both the second temperature information Tb and the first temperature information Tp have gone through the rising phase and reached the stable phase, the second temperature information Tb remains stable within the second temperature range [T0, T1] for t minutes (taking 2 minutes as an example), taking [100-120] as an example, and the first temperature information Tp remains stable within the first temperature range [T2, T3], taking [95, 105] as an example. It is determined that the cooking is steaming or boiling and the water in the pot has boiled. At this time, both the pot and the mobile APP can remind you: the water has boiled, please proceed to the next cooking step.

[0068] like Figure 5 As shown, when a pot without a lid is placed on the stove (i.e., the pot is in the "pot placed" state and the lid is in the "lid removed" state), the second temperature information Tb is recorded in real time. When the second temperature information Tb has gone through the rising stage and reached the stable stage, the second temperature information Tb remains stable within the second temperature range [T0, T1] for t1 minutes (taking 5 minutes as an example). Here, [100-120] is taken as an example. It is determined that the cooking is steaming or boiling and the water in the pot has boiled. At this time, both the pot and the mobile APP will remind you: The water has boiled. Please proceed to the next step of cooking.

[0069] This invention can intelligently determine when the water in a pot is boiling, based on a comprehensive assessment of the temperature information from the lid and bottom of the pot. It promptly notifies the cook when the water is boiling, saving cooking effort.

[0070] In some embodiments, if the water in the smart cooker boils, the smart cooker determines the stove setting based on first temperature information, second temperature information, cooker status, and / or lid status; the smart cooker uses the stove setting as instruction information for the stove.

[0071] like Figure 5 As shown, this embodiment can reduce the heat of the stove when the water in the pot is boiling, thereby reducing or preventing overflow.

[0072] Once the water has boiled, when the lid is placed on the cookware and the cookware is placed on the stove (i.e., the cookware is in the "placed" state and the lid is in the "lid in place" state), the cookware instructs the stove to reduce the heat level by one. It then checks whether the second temperature information Tb is stable within the second temperature range [T0, T1] (selected as [100, 120]) within t2 minutes (2 minutes as an example), and whether the first temperature information Tp is stable within the first temperature range [T2, T3] (selected as [95, 105]). If both are within the range, the cookware instructs the stove to reduce the heat level by another one, until the second temperature information Tb remains consistently below the first temperature range [T0, T1] or the first temperature information Tp remains consistently below the second temperature range [T2, T3] within t2 minutes. At this point, the cookware instructs the stove to increase the heat level by one and then stabilize it.

[0073] When a pot without a lid is placed on the stove (i.e., the pot is in the "pot placed" state and the lid is in the "lid removed" state), it is determined whether the second temperature information Tb of the pot is stable within the second temperature range [T0, T1] within t3 minutes (3 minutes as an example). This range is selected as [100, 120]. If it is within the range, the pot notifies the stove to reduce the heat by one level until the second temperature information Tb is continuously lower than the second temperature range [T0, T1] within t2 minutes. Then, the pot notifies the stove to increase the heat by one level and stabilize the heat.

[0074] This invention allows for reducing the stove's heat when water boils, thus reducing or preventing overflow. After the water boils, the pot instructs the stove to lower the heat, reducing the boiling point and thereby minimizing or preventing overflow.

[0075] The method provided in this invention can intelligently adjust the range hood's airflow based on the cooking scenario. It comprehensively judges the amount of oil fumes generated by the cookware based on information such as the pot bottom temperature, pot lid temperature, and whether the pot lid is in place, and adjusts the range hood's airflow accordingly. When there is a lot of oil fumes, the range hood's airflow is increased; when there is a little oil fumes, the airflow is decreased, ensuring effective fume extraction while reducing noise. It can also intelligently determine when the water in the pot is boiling, based on information such as the pot lid and pot bottom temperatures. When the water boils, it promptly notifies the cook, saving cooking effort. Furthermore, it can reduce the stove's heat when the water boils, reducing or preventing overflow. After the water boils, the cookware notifies the stove to reduce the heat, decreasing the degree of boiling and thus reducing or preventing overflow.

[0078] The stove in this embodiment is also equipped with a communication module. The communication module of the stove can obtain the instruction information sent by the communication module of the smart cookware. The stove performs actions based on the instruction information, thereby realizing the linkage control between the stove and the smart cookware.
