DETAILED DESCRIPTION

[0058] The following further describes the embodiments of the present application in conjunction with the accompanying drawings. Throughout the accompanying drawings, the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions. Furthermore, the embodiments of the present application described below in conjunction with the accompanying drawings are exemplary and are intended only to explain the embodiments of the present application and are not to be construed as limiting the present application.

[0059] See also Figures 1 to 4 The stove power display control method of the embodiment of the present application is applied to a stove 100. The stove 100 includes a mechanical knob 10 and a potentiometer 20. The mechanical knob 10 is connected to the potentiometer 20. When the mechanical knob 10 rotates, the potentiometer 20 rotates synchronously, causing the resistance of the potentiometer 20 to change. The stove 100 is in communication with a range hood 200. The range hood 200 includes a control panel 210. The control method includes:

[0060] S11: Obtain the output voltage of the potentiometer 20;

[0061] S12: Determine the gas flow rate of the stove 100 according to the output voltage;

[0062] S13: The gas flow rate is sent to the range hood 200 so that the control panel 210 displays the fire status corresponding to the gas flow rate.

[0063] In the stove power display control method of the embodiment of the present application, a mechanical knob 10 is connected to a potentiometer 20. Rotating the mechanical knob 10 drives the potentiometer 20 to rotate synchronously, causing its resistance to change. By obtaining the output voltage of the potentiometer 20, the gas flow rate of the stove 100 can be determined. This gas flow rate is then transmitted to the range hood 200, which displays the corresponding power status on the control panel 210. This allows the stove 100 power status to be displayed as visual data on the range hood 200 control panel 210, effectively resolving the issue of users having difficulty accurately and promptly identifying the stove 100 power status.

[0064] See also Figure 2 and Figure 3The cooker 100 may include a mechanical knob 10 , a potentiometer 20 , a main control module 30 and a first wireless module 40 .

[0065] Specifically, the mechanical knob 10 serves as a user-operated component. By rotating the mechanical knob 10, the user can adjust the gas flow rate of the stove 100, thereby adjusting the heat level of the stove 100. Different rotation angles of the mechanical knob 100 result in different gas flow rates and, consequently, different heat levels. In one example, the rotation angle of the mechanical knob 10 is directly related to and proportional to the gas flow rate of the stove 100; that is, the greater the rotation angle, the greater the gas flow rate. Of course, in other examples, the rotation angle of the mechanical knob 10 may not be proportional to the gas flow rate of the stove 100, and this is not intended to be limiting.

[0066] Potentiometer 20 is a variable resistor that can be composed of a resistor body, a sliding contact, and a rotating shaft. When the rotating shaft rotates, the sliding contact moves on the resistor body, changing the resistance length of the circuit, thereby changing the resistance value.

[0067] The mechanical knob 10 is connected to the potentiometer 20. The potentiometer 20 can be installed below the mechanical knob 10, that is, on the side close to the interior of the cooker 100. When the mechanical knob 10 rotates, it drives the potentiometer 20 to rotate synchronously. In one example, the mechanical knob 10 and the potentiometer 20 are connected by a physical structure such as a gear and a shaft, and the rotation angle of the mechanical knob 10 is consistent with the rotation angle of the potentiometer 20. For example, when the rotation angle θ of the mechanical knob 10 is θ, the rotation angle θ of the potentiometer 20 is also θ. When the rotation angle θ of the mechanical knob 10 is different, the rotation angle θ of the potentiometer 20 is different, resulting in a different resistance R of the potentiometer 20 and, consequently, a different output voltage of the potentiometer 20.

[0068] The main control module 30 serves as the control center of the functions of the cooker 100. As mentioned above, when the rotation angle of the mechanical knob 10 is different, the output voltage of the potentiometer 20 is different. Therefore, the main control module 30 can use the built-in analog-to-digital converter (ADC) to perform voltage sampling and detect the resistance of the potentiometer 20 as R i The output voltage V i Then, according to the output voltage V of the potentiometer 20 i Identify the rotation angle of the mechanical knob 10. As mentioned above, when the rotation angle of the mechanical knob 10 is different, the gas flow rate of the stove 100 is different. Therefore, the main control module 30 can further identify the gas flow rate Q of the stove 100 according to the rotation angle of the mechanical knob 10. i .

[0069] From the above, we can see that the output voltage V of the potentiometer 20 is i The gas flow Q of the stove 100i There is a corresponding relationship between them, therefore, according to the output voltage V of the potentiometer 20 i The gas flow Q of the stove 100 can be accurately determined i In practical applications, the main control module 30 can directly output the voltage V i Determine the corresponding gas flow Q i Alternatively, the main control module 30 may also firstly calculate the output voltage V i Determine the rotation angle of the mechanical knob 10, and then determine the gas flow Q of the stove 100 according to the rotation angle i It is understood that when the mechanical knob 10 is closed (ie the rotation angle is 0), the gas flow rate Q of the stove 100 is i =0, the output voltage V of the potentiometer 20 i =V0. Wherein, V0 is the output voltage when the rotation angle of the potentiometer 20 is 0.

[0070] The first wireless module 40 is a hardware component integrated into the cooker 100 that enables wireless communication between the cooker 100 and the range hood 200. After determining the gas flow rate of the cooker 100 in the manner described above, the first wireless module 40 can transmit the gas flow rate to the range hood 200, which then displays the corresponding power level on the control panel 210.

[0071] In the above technical solution, the gas flow rate of cooker 100 is determined based on the output voltage of potentiometer 20, eliminating the need for an additional flow sensor and reducing hardware and maintenance costs. Furthermore, since rotation of the mechanical knob 10 synchronously rotates the potentiometer 20, and the output voltage of the potentiometer 20 changes in real time with the rotation angle of the mechanical knob 10, the gas flow rate of cooker 100 is determined based on the output voltage of the potentiometer 20 with high accuracy and real-time performance, enabling users to accurately and promptly perceive the power level of cooker 100.

[0072] See also Figure 4 The range hood 200 may include a control panel 210 and a second wireless module 220 .

[0073] Specifically, the second wireless module 220 is a hardware component integrated in the range hood 200 for implementing wireless communication between the range hood 200 and the stove 100. The second wireless module 220 receives the gas flow sent by the stove 100 by communicating with the first wireless module 40.

[0074] The control panel 210 serves as the display and operation control center for the range hood 200. The control panel 210 displays the power level corresponding to the gas flow rate, visualizing the power level of the stove 100 and allowing the user to accurately and promptly identify the power level of the stove 100. After the user adjusts the gas flow rate using the mechanical knob 10, the user can also promptly identify the power level changes of the stove 100 on the control panel 210.

[0075] See also Figure 2 、 Figure 3 and Figure 5 In some embodiments, determining the gas flow rate of the cooker 100 according to the output voltage (ie, S12) includes:

[0076] S121: Determine the rotation angle of the mechanical knob 10 according to the output voltage;

[0077] S122: Determine the gas flow rate of the stove 100 according to the rotation angle.

[0078] Specifically, Figure 6 For example, Figure 6 The figure shows the gas flow rates (and thus the different heat levels) corresponding to the different rotation angles of the mechanical knob 10. The mechanical knob 10 rotates counterclockwise. When the rotation angle is 0 degrees (off), the gas flow rate is 0 (no heat). When the rotation angle is 90 degrees, the gas flow rate is at its maximum (maximum heat). When the rotation angle is 315 degrees, the gas flow rate is at its minimum (minimum heat). The following examples are provided for clarity and accuracy.

[0079] It can be seen that different rotation angles of the mechanical knob 10 correspond to different gas flow rates. After the main control module 30 determines the rotation angle of the mechanical knob 10 according to the output voltage of the potentiometer 20, the gas flow rate of the stove 100 can be accurately determined according to the rotation angle.

[0080] See also Figure 7 In some embodiments, the control method further comprises:

[0081] S14: Obtaining the working status of the stove 100;

[0082] S15: The working status is sent to the range hood 200 so as to be displayed via the control panel 210 .

[0083] Specifically, the main control module 30 can obtain the operating status of the stove 100. The operating status of the stove 100 includes, but is not limited to, the operating mode, timing status, and fault status of the stove 100. The operating mode may include normal cooking mode, stir-fry mode, and keep-warm mode. The timing status may include whether the stove 100's timing function is enabled and the remaining time. The fault status may include safety alarm information such as gas leaks, flame outages, and sensor abnormalities.

[0084] After the main control module 30 obtains the operating status of the cooker 100, it transmits this status in real time to the range hood 200 via the first wireless module 40. Correspondingly, the second wireless module 220 receives the operating status and displays it in real time on the control panel 210. This enables real-time synchronization and visualization of status information between the cooker 100 and the range hood 200, improving the user experience (indicating operating mode and timing status) and enhancing system security (indicating fault status).

[0085] See also Figure 8 In some embodiments, the control method further comprises:

[0086] S16: Detecting the placement status of the pot on the cooker 100;

[0087] S17: Sending the pot placement status to the range hood 200 so as to display the pot placement status through the control panel 210.

[0088] Specifically, see Figure 2 The stove 100 may also include a pot detection module 90, which is used to detect the placement of a pot on the stove 100, that is, to detect whether a pot is placed on the stove 100. In some examples, the pot detection module 90 may be a pot detection device with an elastic structure mounted on the stovetop of the stove 100. When a pot is placed on the stove 100, the weight of the pot compresses the elastic structure, triggering the pot detection device to output a first signal. When the pot is removed from the stove 100, the elastic structure rebounds, causing the pot detection device to output a second signal. The first signal can be used to determine whether a pot is placed on the stove 100; the second signal can be used to determine whether a pot is placed on the stove 100.

[0089] After the pot detection module 90 detects the pot placement status, it can send the pot placement status to the range hood 200 in real time through the first wireless module 40. Correspondingly, the second wireless module 220 can receive the pot placement status and display the pot placement status in real time through the control panel 210, thereby improving the user experience.

[0090] Further, the control panel 210 can also perform feedback control on the gas flow of the cooktop 100 according to the pot placement state, so as to adjust the fire state of the cooktop 100. For example, when no pot is placed on the cooktop 100, the control panel 210 can send a control command to the cooktop 100 through the communication between the second wireless module 220 and the first wireless module 40, so as to control the electromagnetic valve inside the cooktop 100 to reduce the gas flow, thereby automatically reducing the fire of the cooktop 100. Within a predetermined time, when the pot is placed on the cooktop 100 again, the control panel 210 can send a control command to the cooktop 100 through the communication between the second wireless module 220 and the first wireless module 40, so as to control the electromagnetic valve inside the cooktop 100 to increase the gas flow, thereby automatically increasing the fire of the cooktop 100, so that the cooktop 100 restores the original fire.

[0091] In the above technical solution, when no pot is placed on the cooktop 100, the gas flow is automatically reduced, and the fire is reduced. This not only reduces unnecessary gas consumption, but also effectively avoids the dry burning caused by the user forgetting to turn off the fire or not placing the pot in time, and reduces the hidden danger of safety fire. When the pot is placed on the cooktop 100 again, the gas flow is automatically increased, and the original fire is restored. The user does not need to manually adjust the fire frequently, and the cooking process is more smooth and convenient. The intelligent linkage control between the cooktop 100 and the range hood 200 is realized.

[0092] Please refer to Figure 2 and Figure 3 In addition to the aforementioned mechanical knob 10, potentiometer 20, main control module 30, first wireless module 40 and pot detection module 90, the cooktop 100 can also include an ignition control module 50, an open valve control module 61, a close valve control module 62, a timing module 70 and an extinguishing detection module 80.

[0093] Specifically, the ignition control module 50 has a linkage relationship with the mechanical knob 10. When it is detected that the mechanical knob 10 rotates, the ignition control module 50 immediately starts the ignition program. In this way, the user can trigger ignition by simply rotating the mechanical knob 10, which is convenient to operate and conforms to the user's usage habit. The ignition control module 50 can adopt a pulse ignition mode. After starting the ignition program, a high-voltage electric pulse is generated and released to the mixed area of gas and air through an ignition needle to ignite the gas, thereby realizing the ignition function of the cooktop 100.

[0094] The valve opening control module 61 is also linked to the mechanical knob 10. When the user rotates the mechanical knob 10, the valve opening control module 61 receives the signal and responds quickly, opening the gas valve. This allows the gas to flow smoothly to the burner of the stove 100, providing gas supply for ignition and subsequent combustion. To ensure precise control of the gas flow, the valve opening control module 61 can work in conjunction with the gas flow regulation system. Based on the angle at which the user rotates the mechanical knob 10, the valve opening degree is precisely controlled according to a preset mapping relationship to meet different firepower requirements.

[0095] The valve closing control module 62 closes the gas valve in two situations. First, when the user actively turns off the flame, for example, by rotating the mechanical knob 10 to the off position, the valve closing control module 62 promptly closes the gas valve, halting the gas supply. Second, when the flameout detection module 80 detects that the stove 100 has stalled, the valve closing control module 62 also immediately closes the gas valve to prevent gas leaks and ensure safety. The valve closing control module 62 has a rapid response capability. Upon receiving a flameout or shutoff signal, it closes the valve in the shortest possible time, minimizing the risk of gas leaks.

[0096] The timing module 70 is used to automatically shut down the flame and valves based on the user-set timer. When the user successfully ignites the stove and the flameout detection module 80 detects a stable flame, the user can set the timer T. This ensures that the timing function is used when the stove 100 is burning normally, avoiding the safety hazards that may arise from setting the timer when the ignition fails or the flame is unstable.

[0097] After the timer T is set, the timing module 70 begins a countdown. During the countdown, the user can view the remaining time in real time. When the timer reaches 0, the timing module 70 sends a signal to the valve closing control module 62, which then closes the gas valve, automatically shutting off the flame and valve, providing a convenient and safe cooking experience for the user.

[0098] The flameout detection module 80 is used to monitor flame status in real time. This can be accomplished using a variety of methods, such as a flame ionization probe or thermocouple sensor. When the flameout detection module 80 detects that the cooker 100 has gone out, the valve shutoff control module 62 immediately closes the gas valve, reducing the gas flow rate to zero. This ensures that the gas supply is promptly shut off after the flame goes out, preventing gas leaks and ensuring safety.

[0099] The following is an example of the collaborative working process of the mechanical knob 10, the ignition control module 50, the valve opening control module 61, the valve closing control module 62, the timing module 70 and the flameout detection module 80.

[0100] The user rotates the mechanical knob 10 , and the ignition control module 50 detects the rotation and starts ignition. At the same time, the valve opening control module 61 opens the gas valve, and gas begins to be supplied.

[0101] If the ignition is successful and the flameout detection module 80 detects the flame, the user can set the timing time T.

[0102] After the timing time is set, the timing module 70 starts counting down. During the countdown, the flameout detection module 80 continuously detects the flame state.

[0103] If the flameout detection module 80 detects that the flame is extinguished during the timing period, the gas flow is controlled to 0, and the valve closing control module 62 closes the gas valve; if the timing time counts down to 0, the timing module 70 triggers the valve closing control module 62 to close the gas valve.

[0104] The user can also actively rotate the mechanical knob 10 to the closed position to trigger the valve closing control module 62 to close the gas valve and realize the fire-off operation.

[0105] Through the collaborative work of the above modules, the stove 100 can realize a series of functions such as ignition, valve opening, valve closing, timing and flameout protection, providing users with a safe, convenient and intelligent cooking experience.

[0106] See also Figures 2 to 4 、 Figure 9 The stove power display control method of the embodiment of the present application is applied to a range hood 200. The range hood 200 includes a control panel 210. The range hood 200 is in communication with the stove 100. The stove 100 includes a mechanical knob 10 and a potentiometer 20. The mechanical knob 10 is connected to the potentiometer 20. When the mechanical knob 10 rotates, the potentiometer 20 rotates synchronously, causing the resistance of the potentiometer 20 to change.

[0109] The control method for the display of the fire power of the stove in the embodiments of the present application is as follows: the mechanical knob 10 is connected with the potentiometer 20, when the mechanical knob 10 rotates, the potentiometer 20 rotates synchronously to change the resistance of the potentiometer 20. The stove 100 can determine the gas flow according to the output voltage of the potentiometer 20. The hood 200 can receive the gas flow sent by the stove 100 and display the fire power state corresponding to the gas flow through the control panel 210. In this way, the fire power state of the stove 100 can be displayed as visual data on the control panel 210 of the hood 200, effectively solving the problem that the user cannot accurately and timely identify the fire power state of the stove 100.

[0110] It should be noted that the above-mentioned embodiments of the control method for the display of the fire power of the stove 100 are also applicable to the control method for the display of the fire power of the stove 100 in the embodiments of the present application, which will not be described here.

[0111] In some examples, the way in which the control panel 210 displays the fire power state corresponding to the gas flow includes but is not limited to ring light display, flame icon display, numerical value display, etc.

[0115] S221: displaying the fire power state corresponding to the gas flow through the second display area.

[0116] Specifically, please refer to Figure 11 The control panel 210 includes a first display area (as shown in S1 area of Figure 11 ) and a second display area (as shown in S2 area of Figure 11 ), two different functional areas.

[0117] The first display area is used to display the working state of the hood 200. The working state of the hood 200 includes but is not limited to the wind speed gear (such as low gear, medium gear, high gear), whether it is in the self-cleaning mode, whether the lighting function is turned on, etc. Through the first display area, the user can intuitively understand the current running mode and the opening of each function of the hood 200.

[0118] The second display area is used to display the fire state of the stove 100. The number of the second display area can be one or more, which is not limited herein. In the embodiments of the present application, since the stove 100 usually has two heating areas (left stove and right stove), the number of the second display area is also two, and the two second display areas are respectively located on the left and right sides of the first display area. The left second display area corresponds to the left heating area of the stove 100, and the right second display area corresponds to the right heating area of the stove 100. Each second display area displays the corresponding fire state according to the gas flow of the corresponding heating area.

[0119] In this way, the user can simultaneously understand the relevant information of the smoke machine 200 and the stove 100 through one control panel 210, without the need to view the two devices respectively, greatly improving the convenience of information acquisition. Further, through the partition design, the integration and classification display of information are realized, so that the user can quickly and accurately acquire the required information, such as the working state of the smoke machine 200 or the fire state of the stove 100.

[0120] In some embodiments, the fire state corresponding to the gas flow is displayed through the second display area (i.e., S221), which includes:

[0121] The different fire states are displayed by controlling the second display area to light up different areas and / or different brightnesses.

[0122] The larger the fire, the larger the area and / or the higher the brightness of the second display area.

[0123] Specifically, the different fire states can be presented by controlling the second display area to light up different areas and / or different brightnesses. The fire state and the lighting area and brightness of the second display area have a positive correlation, that is, the larger the fire, the larger the area and / or the higher the brightness of the second display area. In this way, by using the intuitive perception of the user to the changes in brightness and area, the abstract fire size can be converted into intuitive visual information.

[0124] Please refer to Figure 11 In some examples, the second display area can adopt a multi-ring Light-Emitting Diode (LED) ring design. Please refer to Figure 12 The fire of the stove 100 is divided into inner ring fire and outer ring fire.

[0125] (1) Maximum fire state

[0126] When the fire of the stove 100 is adjusted to the maximum, the multi-ring LED ring is fully lit and the brightness is adjusted to the brightest. The design of the multi-ring LED ring can provide richer and more delicate visual effects, and the display mode of full lighting and brightest can clearly convey to the user that the fire is in the strongest state at this time.

[0127] (2) Fire power adjustment process

[0128] When the fire power of the stove 100 is adjusted, the brightness of the outer ring light belt is gradually dimmed. In this way, the user can clearly perceive that the fire power is gradually decreasing, and intuitively understand the degree of fire power reduction through the change in the brightness of the outer ring light belt.

[0129] When the fire power of the stove 100 is adjusted to the outer ring fire is turned off, the LED light ring corresponding to the outer ring fire is extinguished. In this way, the change of the fire power state is further clarified, and the outer ring fire is turned off corresponding to the extinguishing of the LED light ring of the outer ring, so that the user can accurately judge the fire power distribution of the stove 100.

[0130] When the fire power of the stove 100 is further adjusted, the LED light ring corresponding to the inner ring fire is slowly dimmed. In this way, the gradual dimming process of the LED light ring of the inner ring matches the continuous reduction of the inner ring fire, allowing the user to continuously track the change of the fire power.

[0131] (3) Fire off state

[0132] When the stove 100 is turned off, all the multi-ring LED light rings are extinguished. In this way, it can be clearly indicated that the stove 100 has stopped working and there is no fire power output.

[0133] In some examples, the control panel 210 includes a liquid crystal screen. The liquid crystal screen has multi-functional display characteristics, which can not only display the working state of the hood 200 in real time, but also display the fire power state of the stove 100 synchronously.

[0134] Taking the display of the fire power state of the stove 100 as an example, when the stove 100 is determined to be in different fire powers such as small fire, medium fire, and large fire according to the gas flow, the liquid crystal screen displays icons representing different fire power sizes corresponding to them, respectively. For example, when the stove 100 is in a small fire state, the liquid crystal screen displays a small fire icon; when the stove 100 is in a large fire state, the liquid crystal screen displays a large fire icon; when the stove 100 is in a large fire state, the liquid crystal screen displays a large fire icon.

[0135] During the user's adjustment of the fire power of the stove 100, the liquid crystal screen can respond and update the display of the fire power state in real time. The user only needs to observe the liquid crystal screen on the control panel 210 to clearly identify the change of the fire power of the stove 100, so as to timely grasp the fire power dynamics in the cooking process, and provide strong support for precise cooking.

[0136] In some examples, the control panel 210 can also display the fire state corresponding to the gas flow in the form of a numerical value. Different numerical values correspond to different fire states. For example, the fire size is positively correlated with the displayed numerical value, that is, the larger the fire, the larger the displayed numerical value; the smaller the fire, the smaller the displayed numerical value. In this way, the user can intuitively understand the fire situation of the cooktop 100 through the numerical value displayed on the control panel 210.

[0137] Referring to Figure 13 In some embodiments, the control panel 210 includes a control area. The control method further includes:

[0138] S24: receiving a control instruction input by the user through the control area;

[0139] S25: adjusting the gas flow according to the control instruction to adjust the fire state.

[0140] Specifically, the control panel 210 is provided with a control area (as shown in Figure 14 The control area is used to receive a control instruction input by the user to adjust the gas flow of the cooktop 100 according to the control instruction, thereby adjusting the fire state of the cooktop 100. In one example, the user can input the control instruction by touch operation on the control area.

[0141] The number of control areas can be one or more, which is not limited herein. In the embodiments of the present application, since the cooktop 100 usually has two heating areas (left and right stoves), the number of control areas is also two, and the two control areas are located on the left and right sides of the control panel 210. The left control area corresponds to the left heating area of the cooktop 100, and the right control area corresponds to the right heating area of the cooktop 100. Each control area adjusts the gas flow of the corresponding heating area according to the received control instruction, thereby adjusting the fire state of the corresponding heating area.

[0142] The control area provided on the control panel 210 facilitates the user to simultaneously operate the range hood 200 and the cooktop 100 during cooking. The user does not need to move back and forth between the cooktop 100 and the range hood 200, but can easily complete the adjustment of the fire of the cooktop 100 on the control panel 210 of the range hood 200, greatly improving the convenience and efficiency of cooking. In other examples, the control area can also receive a control instruction input by the user to realize the timing function, on-off function, etc. of the cooktop 100 according to the control instruction.

[0143] In some examples, when adjusting the gas flow rate to adjust the heat level based on a user-input control command, the control zone first receives the user-input control command. Then, via wireless communication between the second wireless module 220 and the first wireless module 40, the control command is transmitted to the stove 100. After receiving the control command, the solenoid valve within the stove 100 begins operating, automatically adjusting to the corresponding solenoid valve angle based on the control command. This change in solenoid valve angle can alter the gas flow rate, thereby adjusting the heat level of the stove 100. For example, when the control command is to increase the heat level, the solenoid valve adjusts to a larger angle, increasing the gas flow rate and consequently increasing the heat level of the stove 100. When the control command is to decrease the heat level, the solenoid valve adjusts to a smaller angle, decreasing the gas flow rate and consequently decreasing the heat level of the stove 100. This automatic adjustment of the solenoid valve allows for precise control of the heat level of the stove 100. Users only need to input control commands in the control zone, eliminating the need for complex operations on the stove 100, providing a more intelligent and convenient cooking experience.
