Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and more specifically, to a dual-compartment hot pot and its control method. Background Technology

[0002] A current type of hot pot with two heating modules includes two heating modules, each with a corresponding adjustment switch. Users may need to adjust the power of only one heating module using one of the switches, or they may need to adjust the power of both heating modules simultaneously using the same switch. Current hot pots typically only allow for one of these needs. For users, only being able to satisfy one need complicates the process of operating the adjustment switch, negatively impacting the user experience and making operation inconvenient.

[0003] In addition, when a hot pot with two compartments can meet the above two needs at the same time, it brings a problem: it lacks a power mode that can automatically switch according to certain scenarios to meet the power adjustment needs. If it can only be switched manually, it is inconvenient for users, the user experience is poor, and the learning cost is high. If the power mode is automatically switched under unsuitable conditions, it will affect the performance of the hot pot. Summary of the Invention

[0004] The purpose of this application is to provide a dual-compartment hot pot and its control method, which solves the problem that existing dual-compartment hot pots cannot simultaneously meet the requirements of individual control of the adjustment switch and simultaneous control of the power of two heating modules, and provides a dual-compartment hot pot and its control method that can automatically switch power modes under appropriate conditions.

[0005] The embodiments of this application are implemented as follows:

[0006] This invention provides a control method for a dual-heating hot pot. The dual-heating hot pot includes two heating modules, an adjustment switch corresponding to each heating module, and a main control unit electrically connected to the heating modules and the adjustment switches. The total power value of the heating modules is less than or equal to a preset threshold. The dual-heating hot pot also has a synchronous adjustment mode and a single-line linkage mode. In the synchronous adjustment mode, if any adjustment switch adjusts the power of its corresponding heating module, the power of the other heating module increases or decreases accordingly. In the single-line linkage mode, when the total power value reaches the preset threshold, the adjustment switch increases the power of its corresponding heating module, and the power of the other heating module decreases accordingly. The control method includes: if the dual-heating hot pot is in the synchronous adjustment mode, when the user increases the power of any heating module through the adjustment switch, if the power of that heating module reaches the preset threshold, and if the user inputs a first signal within a first time period, switching to the single-line linkage mode; if the dual-heating hot pot is in the single-line linkage mode, during the cooking preheating stage, determining whether the power of each heating module has reached the preset threshold, and switching to the synchronous adjustment mode when the power of all heating modules reaches the preset threshold.

[0007] In a preferred embodiment, during the first duration, the hot pot enters a first display mode, which prompts the user to switch modes by displaying the current status; after entering the first display mode, the hot pot ends the first display mode upon receiving the first signal or after the first duration has elapsed.

[0008] In a preferred embodiment, the display status is generated on the display panel of the hot pot, and the display status is a flashing light prompt, a constantly lit indicator light prompt, or a screen display prompt.

[0009] In a preferred embodiment, the first signal is an increased power signal, a confirmation signal, or a start signal.

[0010] In a preferred embodiment, each heating module corresponds to a cooking cavity; when the hot pot is in single-row linkage mode; if the power value of the corresponding heating module is greater than a preset threshold and the temperature of the cooking cavity rises to a first preset limit temperature, the hot pot is controlled to switch to synchronous adjustment mode, and / or, if the power value of the corresponding heating module is less than or equal to the preset threshold and the temperature of the cooking cavity rises to a second preset limit temperature, the corresponding heating module is controlled to stop heating.

[0011] In a preferred embodiment, the step of determining whether the power of each heating module has reached the preset threshold further includes: after starting the second heating module, within a second time period, when the power of all heating modules reaches the preset threshold, switching to synchronous adjustment mode.

[0012] In a preferred embodiment, the hot pot further includes two cooking chambers corresponding to the two heating modules. The method for determining the cooking preheating stage is as follows: determine whether the temperature of the two cooking chambers is less than or equal to a preset limit temperature; if yes, then it is in the cooking preheating stage; if no, then it is in the cooking stage; or, when the main control unit receives an input signal from the user, the hot pot is in the cooking preheating stage within a third time period.

[0013] In a preferred embodiment, the hot pot also includes a switch, which allows the user to manually switch between the synchronous adjustment mode and the single-line linkage mode after inputting the command through the switch.

[0014] In a preferred embodiment, during the cooking process of the hot pot, the power value of the heating module is adjusted continuously, and the adjustment switch is a rotary switch, a capacitive touch switch, or a physical button switch.

[0015] On the other hand, another embodiment of this application proposes a dual-compartment hot pot, which further includes: a pot body, comprising two cooking chambers corresponding to the two heating modules, a corresponding temperature sensor being provided below the pot body for each cooking chamber, the temperature sensor being electrically connected to the main control unit, the heating module having at least one heating load; the main control unit includes a processor and a memory, the memory storing a program, and the processor implementing the dual-compartment hot pot control method as described above when executing the program in the memory.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] By setting both synchronous adjustment mode and single-row linkage mode in the dual-compartment hot pot, the problem that existing dual-compartment hot pots cannot simultaneously meet the requirements of individual control of the switch and simultaneous control of the power of two heating modules is solved. This makes it more convenient for users to adjust the two heating modules and improves the user experience.

[0018] Furthermore, the hot pot and its control method disclosed in this application provide a hot pot and its control method that can automatically switch power modes under suitable conditions. In synchronous adjustment mode, when the user increases the power of any heating module through the adjustment switch, if the power of that heating module reaches a preset threshold, and if the user inputs a first signal within a first time period to switch to single-line linkage mode, when the hot pot is at the boundary of the maximum power in synchronous adjustment mode, the main control unit needs to obtain the first signal for a first time period after outputting the power increase signal through any adjustment switch before performing the mode switching operation. This solves the problem of incorrect mode switching caused by erroneous power increase signals due to misoperation at the boundary of the maximum power value in synchronous adjustment mode, ensuring the performance of the hot pot and improving the user experience.

[0019] In single-row linkage mode, during the preheating stage, it checks whether the power of each heating module has reached a preset threshold. When all heating modules reach the preset threshold, it switches to synchronous adjustment mode. At this point, the heating modules requiring higher power are all switched to synchronous adjustment mode, allowing the user to adjust the power of one heating module simultaneously with the power of the other. This prevents the power of the other heating module from being reduced or even dropping to zero. The higher-power heating modules are automatically switched to synchronous adjustment mode, resulting in a high degree of intelligence in the cooking appliance. This significantly reduces user operation and judgment, lowers the learning curve, and improves the user experience. It also addresses the issue that during the preheating stage, when the power of the two heating modules is adjusted sequentially to a higher power level, the power of the first module adjusted may be lower than the user's expectations because the hot pot is in individual heating module power control mode.

Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples. The technical solutions of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0037] It should be noted in advance that the following descriptions of single-row linkage mode and synchronous adjustment mode refer to one of the power modes of the hot pot. When the power signal output by the main control unit 120 is sent to the corresponding heating module 110, the power value of the heating module 110 will be adjusted according to the power signal. This method is a conventional technique in this field and will not be described in detail below.

[0038] As described in the background section, existing hot pots with two heating modules cannot meet the needs of both individual and simultaneous control of the power of the corresponding heating modules by adjusting the switch. This results in limited applicability, inconvenience for users to adjust the power, and a poor user experience.

[0039] This application provides a dual-compartment hot pot 100. See also: Figure 1The hot pot 100 includes a heating module 110 and a main control unit 120. Each heating module 110 is equipped with a corresponding adjustment switch 130. The main control unit 120 is electrically connected to the heating module 110 and the adjustment switch 130. User-inputted operation signals are processed by the main control unit 120 and then input to the heating module 110 to perform corresponding operations. For example, if the user inputs a power adjustment signal through the adjustment switch 130, the main control unit 120, upon receiving the signal, outputs a corresponding power signal to the corresponding heating module 110, adjusting the power value of the corresponding heating module 110 to the user's desired level. In one embodiment, the heating module 110 is an electromagnetic heating module, whose heating unit includes a control unit and a coil unit. The aforementioned power signal is received by the control unit and then controls the corresponding heating unit to operate at a limited power value. In other embodiments, the heating module 110 can also be an adjustable power heating plate assembly.

[0040] The main control unit 120 is installed on the hot pot 100. The main control unit 120 is used to process various signals to execute various control programs, such as control signals input by the user through the interactive display panel, power adjustment signals output by the adjustment switch 130, or various signals input through the mobile terminal.

[0041] The control program of the main control unit 120 includes at least two power modes, meaning the hot pot 100 also has at least two power modes. In one embodiment of this application, these include a single-row linkage mode that individually controls the power of each heating module and a synchronous adjustment mode that simultaneously controls the power of two heating modules. These two power modes can be manually or intelligently selected to suit the current cooking scenario, offering wide applicability and a good user experience. When the hot pot 100 is first powered on, it can be in synchronous adjustment mode or single-row linkage mode, or set according to actual needs. It is important to note that the total power value of all heating modules 110 must be less than or equal to a preset threshold.

[0042] In synchronous adjustment mode, adjusting the power of any one adjustment switch 130 on its corresponding heating module 110 will simultaneously increase or decrease the power of the other heating module 110. This synchronous adjustment mode allows simultaneous changes in the power of both heating modules 110 via any one adjustment switch 130, meaning the power values ​​of both heating modules 110 can be increased or decreased simultaneously. Therefore, it is convenient for users to adjust the power of both heating modules 110 by adjusting just one adjustment switch 130. In one embodiment, the changes in the power values ​​of the two heating modules 110 are equal. For example, increasing the power value of one heating module by 100W by adjusting one adjustment switch 130 will also increase the power value of the other heating module 110 by 100W, and so on. This better meets the user's intention to simultaneously adjust the power of both heating modules 110 using a single adjustment switch 130, with controllable and rapid adjustments. In another embodiment, when the hot pot 100 is in synchronous adjustment mode, the power of the two heating modules 110 is exactly equal and adjusted at the same time, which makes it convenient for users to heat multiple cooking cavities equally. For example, in a hot pot scenario, each cooking cavity is initially filled with an appropriate amount of water or soup base. At this time, it is necessary to boil all the liquids in all cooking cavities. In order to ensure cooking efficiency, the power of each heating module is quickly increased equally through synchronous adjustment mode, which improves the user experience. One-click to turn on all the heat is more convenient in this cooking scenario.

[0043] In synchronous adjustment mode, the power of each heating module 110 is less than or equal to a preset sub-threshold. That is, the maximum power value of each heating module 110 is the preset sub-threshold. If the power value of a heating module 110 has reached the preset sub-threshold, even if the user inputs an increase power signal through the adjustment switch 130, the power value of the corresponding heating module 110 cannot be increased. At this time, if the other heating module 110 has not reached the preset sub-threshold, its power value can increase in response to the increase power signal, or it can remain unchanged because the power value of the corresponding heating module 110 has not increased. The specific design can be based on actual needs and is not limited here. Preferably, the preset sub-threshold is half of the preset threshold. In this way, when the power values ​​of both heating modules 110 are at the preset sub-threshold, the total power value of the heating modules 110 will not exceed the preset threshold, allowing the performance of the dual-compartment hot pot 100 to be fully utilized without power waste.

[0044] In the single-line linkage mode, when the total power value reaches the preset threshold, the adjustment switch increases the power of the corresponding heating module, and the power of the other heating module decreases accordingly. Each adjustment switch 130 only adjusts the power of its corresponding heating module 110, thereby realizing an individually controlled power mode. For example, when using a single pot in the dual-compartment hot pot 100 or when it is necessary to adjust the heating power of the cooking cavity of one pot, this mode can be well adapted to such cooking scenarios. The difference is that, in the single-row linkage mode, in addition to each regulating switch 130 individually controlling the power of its corresponding heating module 110, when the total power value of the heating modules 110 reaches a preset threshold, if the regulating switch 130 increases the power value of the corresponding heating module 110 and the power value of another heating module 110 is not zero, then the power of the corresponding heating module 110 increases, and the power of the other heating module 110 decreases accordingly to meet the requirement that the total power value is less than or equal to the preset threshold. After the power value of the corresponding heating module 110 has increased to the preset threshold, the power value of the corresponding heating module can no longer be increased, so the power value of the other heating module has dropped to 0 and can no longer be decreased. At this time, the power increase signal output by the regulating switch 130 is invalid and will not increase the power of the corresponding heating module 110.

[0045] When the hot pot is in synchronous adjustment mode and the heating module of the hot pot is at the boundary of the maximum power of the hot pot in this mode, if it directly switches to single-line linkage mode after receiving an increased power signal, it is impossible to avoid the problem of mode switching error caused by the increased power signal being generated by misoperation. This will affect the performance of the hot pot and reduce the user experience.

[0046] For this scenario, the hot pot control method disclosed in this application provides Solution 1: If the hot pot 100 is in synchronous adjustment mode, when the user increases the power of any heating module 110 through adjustment switch 130, if the power of the heating module 110 reaches a preset threshold, and the user inputs a first signal within a first time period, the system switches to single-line linkage mode. In this way, when adjustment switch 130 increases the power of the heating module 110 that has reached the preset threshold, after a confirmation time of the first time period, if the user continues to input the first signal within the first time period, it is confirmed that the user needs the power of the adjusted heating module 110 to be greater than the preset threshold. At this time, the hot pot 100 needs to be switched from synchronous adjustment mode to single-line linkage mode so that the power of the adjusted heating module 110 is greater than the preset threshold. This solution can avoid the problem of mode switching error caused by the user's first increase of the power of any heating module 110 through adjustment switch 130 due to misoperation.

[0047] In another scenario, when the Yuan Yang Hot Pot 100 is first used and is in single-row linkage mode, the user may need multiple heating modules 110 to work at their maximum power. By adjusting the power of two heating modules 110 to the high power level one after another, the power value of the first heating module 110 that is adjusted may be unexpectedly reduced or even reduced to 0 without the user's knowledge. This affects the user experience and also makes the learning cost of the Yuan Yang Hot Pot 100 relatively high.

[0048] For this other scenario, the control method for the hot pot with two compartments disclosed in this application provides a second solution: if the hot pot with two compartments 100 is in a single-line linkage mode, during the cooking preheating stage, it is determined whether the power of each heating module 110 has reached the preset threshold. When the power of all heating modules 110 reaches the preset threshold, it is switched to the synchronous adjustment mode.

[0049] This application divides the working process of the dual-compartment hot pot 100 into a preheating stage and a cooking stage. During the preheating stage, the user typically begins cooking, and the cooking chamber temperature or heating time of the dual-compartment hot pot 100 has not yet reached the required level. Generally, during this stage, the user needs to adjust the activated heating module 110 to its highest possible power, or even its maximum power, to achieve rapid heating or preheating. Upon entering the cooking stage, it can be assumed that the user has already preheated the dual-compartment hot pot 100 or can clearly distinguish the working status of each heating module 110, allowing for more independent control of the power values ​​of each heating module 110.

[0050] Solution 2, designed for another scenario, determines whether the power of each heating module 110 reaches a preset threshold during the preheating stage. If all heating modules reach the preset threshold, it can be assumed that the user wants to adjust the two activated heating modules 110 to the larger or maximum power value of the current state. To prevent the power value of the first heating module 110, which is adjusted to high power, from being unexpectedly reduced or even reduced to 0 due to the hot pot 100 being in single-row linkage mode, and to solve this problem of not conforming to the user's intention and to facilitate subsequent adjustments, the hot pot 100 is switched to synchronous adjustment mode. This ensures that even if the user continues to increase the power value of the second adjusted heating module 110 through the adjustment switch 130, the power of the first adjusted heating module 110 will not be reduced, effectively solving the aforementioned problem. Furthermore, due to the intelligent automatic switching, the user's operation and judgment are greatly reduced, the learning cost of the hot pot 100 is lowered, and the user experience is improved.

[0051] Combining the two solutions mentioned above, the control method for the dual-compartment hot pot disclosed in this application can solve the problem that in the operation of the dual-compartment hot pot 100 with synchronous adjustment mode and single-line linkage mode, manual switching of power mode is required in some scenarios, resulting in poor user experience and high learning cost. Furthermore, intelligent automatic switching can increase the intelligence level of the dual-compartment hot pot 100 and ensure its working performance.

[0052] See Figure 2 The diagram shows a flowchart of one embodiment of the hot pot control method for the two-compartment hot pot disclosed in this application.

[0053] See Figure 2 The control method of the above-mentioned scheme one specifically includes:

[0054] Step S101: When the hot pot 100 is in synchronous adjustment mode, the power values ​​of each heating module 110 change simultaneously. The power value of a single heating module 110 is less than or equal to a preset threshold. In some embodiments, the preset threshold is equal to half of the preset threshold. In other embodiments, the preset threshold can be other values, as long as the total power of the two heating modules is less than the preset threshold when they work according to the preset threshold. Then proceed to step S102.

[0055] Step S102: If the power value of the heating module adjusted by any adjustment switch is equal to the preset threshold, proceed to step S103; otherwise, proceed to step S104.

[0056] Step S103: After the adjustment switch 130 outputs an increased power signal; this increased power signal is usually output by the adjustment switch 130 and received and processed by the main control unit 120. This method is a conventional processing method in the field and will not be described in detail here. It can be understood that in the synchronous adjustment mode, since the power values ​​of each heating module 110 are adjusted simultaneously, when the power value of the heating module 110 whose power has been increased has reached the preset threshold size, in the synchronous adjustment mode, if the adjustment switch 130 continues to output an increased power signal, the heating power of the heating module 110 whose power has been increased will not continue to increase. However, if the hot pot 100 responds to the increased power signal and switches to the single-row linkage mode, it will also increase the power value of the heating module 110 whose power has been increased according to the increased power signal; then proceed to step S105.

[0057] Step S104: Continue operating according to the current working conditions of the hot pot 100.

[0058] Step S105: Determine whether the main control unit 120 has acquired the first signal within the first time period. If yes, proceed to step S106; otherwise, proceed to step S107.

[0059] In some embodiments, the first signal is an increased power signal, that is, the increased power signal output again by the adjustment switch 130. Using this increased power signal as a condition to determine whether to switch to the single-line linkage mode has the advantage of more accurate recognition of the user's strong intention to increase power, thus responding quickly to the user's continued input of increased power signals. This results in better response performance of the hot pot 100 and a better user experience. In other embodiments, the first signal can also be a confirmation signal or a start signal, requiring user confirmation. For example, the user can send a confirmation signal by pressing the confirmation button on the adjustment switch 130, or a start signal by pressing the start button on the hot pot 100 to confirm the user's intention to switch to the single-line linkage mode. This provides stronger operational feedback and a better user experience.

[0060] Step S106: Switch to single-row linkage mode, wherein, in this mode, when the power value of the corresponding heating module 110 is increased so that the total power value is greater than the preset threshold, the power value of the other heating modules 110 is reduced accordingly.

[0061] In synchronous adjustment mode, when the power value of the heating module 110 whose power is being increased has reached the preset threshold, the main control unit 120 receives the first signal within the first duration of the power increase signal output by the adjustment switch 130. This indicates that the power value of the corresponding heating module 110 needs to continue increasing, thus switching the synchronous adjustment mode to single-row linkage mode. In single-row linkage mode, the power limit of a single heating module 110 can reach the preset threshold. If the power value of a single heating module 110 continues to increase, causing the total power value of all heating modules 110 to exceed the preset threshold, the power of other heating modules 110 will be reduced accordingly to ensure that the heating power of all heating modules 110 is less than or equal to the preset threshold. Therefore, although this mode uses one adjustment switch 130 to control the power value of one heating module 110 individually, when one adjustment switch 130 outputs a power increase signal, it may also cause the power values ​​of other heating modules 110 to decrease. Thus, the power values ​​of each heating module 110 change in linkage; specifically, the power values ​​of two heating modules 110 change in linkage.

[0062] In some embodiments, after switching to single-line linkage mode, the power value of the corresponding heating module 110 can be increased according to the previous power increase signal, reducing the need for secondary operations by the user. In other embodiments, the hot pot 100 may not respond to the previous power increase signal and wait for the user to input the power adjustment signal again; the specific settings can be configured according to design requirements.

[0063] Step S107: If not, continue operating according to the current working condition of the hot pot 100.

[0064] In a dual-heating hot pot 100 with two heating modules 110 that simultaneously supports synchronous adjustment mode and single-row linkage mode, the two different power modes can be switched. However, a problem exists: in synchronous adjustment mode, if the power value of each heating module 110 reaches a preset threshold, and the user outputs an increased power signal to the main control unit 120 through a certain adjustment switch 130, and then directly switches to single-row linkage mode, allowing the power value of the corresponding heating module 110 to exceed the preset threshold, it is impossible to avoid the situation where the increased power signal is generated by accidental touch or other misoperation. In this case, directly switching modes will affect the normal cooking of the dual-heating hot pot 100, reduce its performance, and require the user to promptly detect and manually correct the problem, causing inconvenience and reducing the user experience.

[0065] The control method of the above-disclosed scheme 1 can solve the problem of incorrect switching of power distribution mode due to misoperation. The working principle is as follows: When the hot pot 100 is in synchronous adjustment mode, when the power value of the heating module 110 whose power is increased has reached the preset threshold, it can be known that the power value of the heating module 110 whose power is increased has reached the boundary value in this mode. At this time, if the adjustment switch 130 outputs an increased power signal or the main control unit 120 obtains an increased power signal, it will determine whether the main control unit 120 has obtained the first signal within the first time period. If the first signal is obtained, it can be considered that the power value of the heating module 110 whose power is increased needs by the user or the main control unit exceeds the preset threshold, and the current power mode does not meet the requirements. Then, it switches to single-line linkage mode to meet the power adjustment requirements. In addition, when necessary, the power values ​​of the other heating modules 110 will be reduced accordingly to meet the requirement that the total power value of all heating modules 110 is less than the preset threshold.

[0066] The proposed method for controlling a dual-compartment hot pot, in Scheme 1, determines whether the main control unit 120 receives the first signal within a reasonable first time period after the adjustment switch 130 outputs an increased power signal or the main control unit 120 receives the increased power signal, and only then performs the mode switching operation. This effectively solves the problem that the increased power signal received for the first time in this boundary condition is due to misoperation, causing the dual-compartment hot pot 100 to directly switch to single-line linkage mode. Such a problem not only inconveniences the user but also affects the cooking performance of the dual-compartment hot pot 100. Scheme 1 ensures that the switching action is performed when switching to single-line linkage mode is required, while avoiding accidental touches. Preferably, the first time period is 0.5-10 seconds. This range allows for reasonable waiting for the user to perform an operation that generates the first signal, without waiting for too long and affecting the normal operation of the dual-compartment hot pot 100.

[0067] In some embodiments of Scheme 1 of this application, while in step S105, the hot pot 100 enters the first display mode, and the first display mode prompts the user to enter the mode waiting to be switched by displaying the status.

[0068] During step S105, the hot pot 100 enters a monitoring state with a waiting time of one duration. When the first signal is received, a mode switch will occur. However, a problem exists: users may not be aware that the hot pot 100 is in this monitoring state, and may not know that generating the first signal within the first duration can directly switch the hot pot 100 to the single-line linkage mode. To solve this problem and fully utilize the advantages of the control method of Scheme 1 disclosed in this application, this embodiment adds a first display mode within the first duration. The set display indicates the current mode switching status, improving the user's awareness of this monitoring state and ensuring that the user knows that the current mode may need to be switched. The operation of generating the first signal to switch to the single-line linkage mode can be written in the user manual, on the outer shell of the hot pot 100, or communicated to the user via voice when the mode is waiting to be switched. This improves the user experience of the hot pot 100, and the hot pot 100 using this control method has a high degree of intelligence.

[0069] For the first display mode scheme, the first display mode needs to be stopped under certain conditions; see [link / reference]. Figure 3 This application provides a control method for ending the first display mode as follows:

[0070] Step S201: After entering the first display mode; proceed to step S202;

[0071] Step S202: After obtaining the first signal or after a first duration, proceed to step S203;

[0072] Step S203: The first display mode of the hot pot (100) ends.

[0073] The advantage of this control method for ending the first display mode is that it stops the first display mode in a timely manner when the mode switching state has ended, ensuring that the other display modes of the hot pot 100 can work normally.

[0074] Specifically, in some embodiments, the display status occurs on the display panel of the dual-compartment hot pot 100. This display includes, but is not limited to, prompts via flashing lights, constantly lit indicator lights, or screen display. This method clearly indicates the current mode is about to switch, making it easy for users to notice and take timely action, preventing them from being unaware and failing to perform their cooking needs. Such display methods are common in the electrical appliance field and will not be elaborated upon or limited here. In other embodiments, the display status can also occur in other locations within the dual-compartment hot pot 100, or it can be a simple voice prompt, as long as it serves its purpose.

[0075] In some embodiments of this application, after the hot pot 100 switches to single-row linkage mode, the hot pot 100 may have different power values ​​for different cooking cavities 210. Therefore, a safety-considered control method can be added to the heating modules 110 with different power values. In one embodiment, this safety-considered control method includes:

[0076] When the hot pot 100 is in single-row linkage mode, if the power value of the corresponding heating module 110 is greater than the preset threshold and the temperature of the cooking cavity 210 rises to the first preset limit temperature, then the hot pot 100 is switched to synchronous adjustment mode; otherwise, it continues to work.

[0077] In another embodiment, the control method for this safety consideration includes:

[0078] When the hot pot 100 is in single-row linkage mode, if the power value of the corresponding heating module 110 is less than or equal to the preset threshold and the temperature of the cooking cavity 210 rises to the second preset limit temperature, then the corresponding heating module 110 is controlled to stop heating; otherwise, it continues to work.

[0079] The two safety-related control methods described above can be applied simultaneously to the dual-compartment hot pot 100. They have different applications for different scenarios. For example, if the heating power of the cooking cavity 210 is greater than a preset threshold, and the temperature of the cooking cavity 210 rises to a certain level, it indicates that the temperature of the cooking cavity 210 has reached the required temperature, such as at the beginning of hot pot cooking, indicating that the water has boiled. At this point, higher heating power is not needed, and the system can switch back to synchronous adjustment mode. In synchronous adjustment mode, the maximum power value of a single heating module 110 is further limited to below the preset threshold, thereby reducing potential safety issues under higher power. Conversely, if the heating power of the cooking cavity 210 is less than the preset threshold, and the temperature of the cooking cavity 210 also rises to a certain level, it may indicate that the liquid in this area has been depleted, resulting in a significant temperature rise even with lower power. In this case, the heating module 110 of this cooking cavity 210 can be stopped to further ensure the safe use of the dual-compartment hot pot 100. Preferably, the second preset limit temperature is lower than the first preset limit temperature. For heating modules 110 with lower power, the temperature rise of their cooking chamber 210 may be smaller. Therefore, a second preset limit temperature with a smaller temperature value can be used as the determination condition.

[0080] See Figure 4 The diagram shows a flowchart of an embodiment of a second scheme of the hot pot control method disclosed in this application.

[0081] The following description of Scheme 2 includes the case where there are two or more heating modules 110. The case with two heating modules 110 also conforms to the description. It should be noted that when the number of heating modules 110 is greater than two, there is a situation in the power mode of the hot pot 100 where multiple heating modules 110 are in synchronous adjustment mode, but there are heating modules 110 in single-row linkage mode. In this case, the hot pot 100 as a whole is in single-row linkage mode.

[0082] See Figure 4 The control methods of Scheme 2 mentioned above specifically include:

[0083] Step S301: Determine if the cooking preheating stage is in progress: if yes, proceed to step S302; if no, proceed to step S303.

[0084] Step S302: Determine if any activated heating modules are in single-row linkage mode; if yes, proceed to step S304; if no, proceed to step S305.

[0085] It is understandable that the power value change of heating module 110 will only affect the power of other activated heating modules 110 when heating module 110 is activated. Therefore, in the second scheme of the hot pot control method disclosed in this application, the hot pot 100 has at least two heating modules 110. The control method of the second scheme will only run when at least two heating modules 110 are activated, but it does not restrict the unactivated heating modules 110.

[0086] It should be noted that there is a boundary case: if the aforementioned power signal causes the power value of a single heating module 110 to exceed a preset threshold or causes the total power value of the corresponding heating modules 110 to exceed a preset threshold, the main control unit 120 will only output a power signal that makes the power value of the heating module 110 equal to the preset threshold. In this way, the safe use of the hot pot 100 can be ensured. In one embodiment, there are three or more heating modules 110, and there may be one or more common heating modules in a synchronous adjustment mode. The power values ​​of the common heating modules change simultaneously. Preferably, the power values ​​of each heating module 110 in the common heating module change synchronously and are equal. Therefore, when there are also heating modules 110 in a single-row linkage mode, the power values ​​of the common heating modules increase or decrease synchronously. Therefore, the power value of the corresponding heating module also includes the sum of the power values ​​of the common heating modules. The common heating module and other non-common heating modules are in a single-row linkage power mode. It is understandable that as long as there is a heating module 110 that is still in single-row linkage mode, the power distribution of the hot pot 100 will generally be in single-row linkage mode.

[0087] Step S303: If not, it is determined that the hot pot 100 is in the cooking stage and continues to work according to the current power mode of the hot pot 100.

[0088] Step S304: The main control unit 120 determines whether the N power values ​​of the N activated heating modules 110 are all equal to a preset threshold. The preset threshold is 1 / N times the preset threshold, and N ≥ 2. It can be seen that in single-row linkage mode, when increasing the power value of a certain heating module 110 until it is about to exceed the preset threshold, while the power values ​​of the other activated heating modules 110 are already equal to the preset threshold, and further increasing the power value of that heating module 110 would cause the total power value to exceed the preset threshold, the main control unit 120 will control the power values ​​of the other activated heating modules 110 to decrease. To ensure that the total power value of all activated heating modules 110 is less than or equal to a preset threshold, and considering that the power values ​​of other activated heating modules 110 have been increased to the preset threshold during the cooking preheating stage, it is known that the user does not want the power values ​​of the remaining heating modules 110 to be reduced. Therefore, this condition serves as the basis for deciding whether to switch all activated heating modules 110 to the synchronous adjustment mode. This prevents the heating modules 110 from having their power values ​​reduced or even reduced to 0 when the user wants multiple heating modules 110 to operate at the maximum achievable power during the cooking preheating stage. Since this control method only has the aforementioned effect when two heating modules 110 are activated, N≥2. Setting the preset threshold to 1 / N times the preset threshold has the advantage of accurately identifying the user's intention to adjust a specific heating module 110 to a higher power level; if yes, proceed to step S306; if no, proceed to step S307.

[0089] Step S305: If not, continue to operate in the current power mode of the hot pot 100.

[0090] Step S306: If yes, then switch all activated heating modules 110 to synchronous adjustment mode, wherein the power value of each heating module 110 changes simultaneously.

[0091] In one embodiment, each activated heating module 110 switches to synchronous adjustment mode and its power value is adjusted to a preset threshold value to ensure that each activated heating module 110 operates at the preset threshold value. In other embodiments, each activated heating module 110 switches to synchronous adjustment mode and its power value is adjusted to other preset power values.

[0092] It is understood that controlling all activated heating modules 110 to switch to synchronous adjustment mode involves binding the currently activated heating modules 110 together before switching to synchronous adjustment mode. Heating modules 110 that are not yet activated, or those to be activated later, will not be bound or switched. For example, if a heating module 110 in single-row linkage mode is activated later, its power adjustment will be independently controlled by its corresponding adjustment switch 130. The entire system of this module and the heating modules 110 bound together in synchronous adjustment mode is in single-row linkage mode. In this case, the total power value of the heating modules 110 bound together in synchronous adjustment mode changes in conjunction with the total power value of the heating modules 110 in single-row linkage mode, and the sum of the two does not exceed a preset threshold. Specifically, for the heating modules 110 bound together in synchronous adjustment mode, their respective adjustment switches 130 can simultaneously adjust the power value of each bound heating module 110, and the power values ​​of each bound heating module 110 are equal.

[0093] Step S307: If not, continue to operate in the current power mode of the hot pot 100.

[0094] By using the control method described in Scheme 2 above, the problem can be solved in existing hot pot 100 with multiple heating modules 110 where, during the cooking preheating stage, the power value of each heating module 110 is individually controlled. In this single-row linkage mode, the power value of the unadjusted heating module might be unexpectedly reduced or even reduced to zero when the user wants multiple heating modules 110 to operate at high power. With this solution, when the power of all activated heating modules 110 is equal to a preset threshold during the cooking preheating stage, it can be assumed that the user wants to adjust the corresponding activated heating module 110 to its maximum or highest power value. To prevent the unadjusted heating module's power value from being unexpectedly reduced or even reduced to zero due to the presence of a heating module 110 in single-row linkage mode, and to facilitate subsequent user adjustments, the corresponding activated heating modules 110 are switched to a synchronous adjustment mode. This effectively solves the aforementioned problem. Furthermore, due to the intelligent automatic switching, the user's operation and judgment are greatly reduced, lowering the learning cost of the hot pot 100 and improving the user experience.

[0095] It is understood that the power distribution parameters of the hot pot 100 are all processed by the main control unit 120. Therefore, the main control unit 120 can obtain the power status of each heating module 110 in real time. Thus, the main control unit 120 can promptly determine whether the power values ​​of the N activated heating modules have reached the preset threshold. Therefore, after reading the specific embodiments provided in this application, those skilled in the art can make the judgment in step S304 by changing the power of each heating module 110 or by making a cyclic judgment, thereby implementing the hot pot control method of this application in the hot pot 100.

[0096] The preset sub-threshold is 1 / N times the preset threshold. For example, when only one heating module is activated, the preset sub-threshold is equal to the preset threshold; when two heating modules are activated, the preset sub-threshold is half the preset threshold, and so on. In this way, by reducing the preset sub-threshold according to the number of activated heating modules 110, the system can more promptly identify the user's intention to adjust all activated heating modules 110 to a higher power value for rapid heating, resulting in a faster response, reduced user waiting time, and further improved user experience. In a dual-compartment hot pot 100 with two heating modules 110, the preset sub-threshold is fixed at half the preset threshold to ensure that the dual-compartment hot pot 100 can operate at full power.

[0097] For step S304, see [link to other embodiments]. Figure 5 It also includes:

[0098] Step S304': After the Nth heating module 110 is activated, within a second time period, the main control unit determines whether the N power values ​​of the N activated heating modules are all equal to the preset threshold. The second time period is a reasonable waiting time after a certain heating module 110 is activated. If the main control unit 120 still does not output a power signal to adjust the power value of a certain heating module 110 to the preset threshold within the second time period after the heating module 110 is activated, it can be considered that it is not necessary for all activated heating modules 110 to operate at their corresponding maximum power. Therefore, if the waiting time exceeds the second time period, the hot pot 100 is controlled to continue operating in the original power mode. The setting of the second time period can reasonably wait for the user's intention to switch all activated heating modules 110 to the synchronous adjustment mode, solving the problem that the hot pot 100's performance is affected by the unlimited judgment of the conditions in step S304' after a certain heating module 110 is activated. The detection of the second duration can be achieved by setting a timer in the main control unit 120, which is a conventional technique in this field and will not be elaborated here.

[0099] Specifically, in the hot pot 100 with two heating modules 110, step S304' is to switch to synchronous adjustment mode after starting the second heating module 110 and within the second time period when the power of all heating modules 110 reaches the preset threshold. For the hot pot 100 with two heating modules 110, this control method is executed after starting the second heating module 110. The hot pot control method of Scheme 2 is less prone to errors and ensures the normal operation of the function.

[0100] In another embodiment, for step S304', the preset sub-threshold decreases as the number of activated heating modules 110 increases. Therefore, the second duration can also decrease as the number of activated heating modules 110 increases. As the number of activated heating modules 110 increases, the preset sub-threshold decreases. Based on user input, the time required for the main control unit 120 to output a power signal that sets the power value of the currently activated heating module 110 to the preset sub-threshold may also decrease. Therefore, reducing the second duration as the number of activated heating modules 110 increases is more in line with actual scenario needs, and the control method of Scheme 2 of this application will be more precise. Preferably, the value range of the second duration is 1s-5min. This range can meet the time interval for users to adjust the power of the activated heating module 110 to the preset sub-threshold in most scenarios, thus adapting to a wide range of scenarios.

[0101] During the operation of the hot pot 100, the power value of the heating module 100 is adjusted continuously, which is a conventional technical method in this field and will not be described in detail here.

[0102] Regarding the question of under what operation the heating module 110 is activated, the following is a brief explanation. When a heating module 110 has not yet been activated, in some embodiments, after the power adjustment signal input by the user is transmitted to the main control unit 120, the main control unit 120 will directly output the power signal to the corresponding heating module 110 power value setting. If the heating module 110 has not been activated, it will be activated directly. That is, in this embodiment, the main control unit 120 adjusts the power value of the heating module 120 continuously. The power value of the heating module 110 changes continuously from 0 to the maximum power value, which makes it easy to implement step S304 or step S304'. In the field of hot pot, knobs or touch buttons are often used to achieve stepless adjustment of the power value of the heating module 110.

[0103] In other embodiments, after the user inputs a power setting signal, the main control unit 120 records the power value indicated by the power setting signal. Only after the main control unit 120 receives a confirmation signal from the user will it output a power signal indicating the recorded value to the corresponding heating module 110 for startup and power adjustment. It should be noted that the heating module 110 will be started before the power setting is performed. Therefore, in this embodiment, the purpose of step S304 or step S304' can still be achieved. However, step S304" is now defined as: the main control unit 120 determines whether the N power values ​​of the N heating modules to be started are all greater than or equal to a preset threshold. This embodiment is equivalent to performing step S304' on the N heating modules 110 to be started, which can also achieve the problem to be solved by this application.

[0104] For step S304, see [link to other embodiments]. Figure 6 It also includes:

[0105] If so after step S302, proceed to step S304a;

[0106] Step S304a: After the Nth heating module 110 is activated, determine whether N is equal to 2 or whether the previous N-1 activated heating modules 110 are all in synchronous adjustment mode; if yes, proceed to step S304b; if no, proceed to step S304c.

[0107] Step S304b: The main control unit determines whether the power value of the Nth activated heating module is equal to the preset threshold; if yes, proceed to step S306; if no, proceed to step S307.

[0108] Step S304c: If not, continue to operate in the current power mode of the hot pot 100.

[0109] Step S304a proceeds directly to the judgment in step S304b after the second heating module 110 is activated; or after the third or more heating modules 110 are activated, it is determined whether the heating modules 110 activated before this heating module 110 are all in the synchronous adjustment mode.

[0110] If the first N-1 activated heating modules 110 are already in synchronous adjustment mode, and the first N-1 activated heating modules 110 are common heating modules, then the power values ​​of the first N-1 activated heating modules 110 are synchronously adjusted. The Nth activated heating module 110 is in single-line linkage mode, and is controlled individually by its corresponding adjustment switch 130. Therefore, when the power value of the Nth activated heating module 110 increases to the preset threshold, it can be known that the user needs to adjust the Nth activated heating module 110 to the high power that can be achieved together.

[0111] To prevent the power values ​​of the first N-1 activated heating modules from being reduced due to excessive power increases by the user, this application proceeds to step S304b after determining "yes" in step S304a. Step S304b only checks whether the power value of the Nth activated heating module 110 is equal to a preset threshold, without needing to obtain the power values ​​of all activated heating modules 110 for judgment. This makes the program execution faster, simpler, and less prone to errors, ensuring the execution of the control method of Scheme 2 of this application and guaranteeing the performance of the hot pot 100. After determining "no" in step S304b, the application proceeds to step S304c without further judgment, directly maintaining the current power mode of the hot pot 100. This makes the program more reasonable and reduces waiting time.

[0112] The following section details the criteria for determining the preheating stage of cooking. See [link / reference]. Figure 1 The hot pot 100 also includes at least two cooking chambers 210, with each heating module 110 corresponding to a cooking chamber 210. See also Figure 7 In one embodiment, the method for determining the cooking preheating stage is as follows:

[0113] Step S401: Determine whether the temperature of the cooking cavity corresponding to all activated heating modules is less than or equal to the preset limit temperature; if yes, proceed to step S402; if no, proceed to step S403.

[0114] Step S402: If so, then the cooking preheating stage is underway;

[0115] Step S403: If not, then proceed to the cooking stage.

[0116] The hot pot control method of this application is applied to a hot pot 100 including two heating modules 110. Therefore, during the cooking preheating stage, the user will activate the corresponding heating module 110 for the cooking cavity 210 that needs to be heated. In order to ensure that the hot pot 100 can be used accurately, it is only necessary to judge the temperature of the cooking cavity corresponding to the activated heating module 110. The advantage of this judgment method is that it can accurately determine whether the current temperature conditions meet the cooking requirements by measuring the temperature of the cooking chamber 210. For example, if it is a boiling water or hot pot mode, the boiling point of the water or soup base is around 100℃. If the preset limit temperature is set to 100℃, then if the temperature of any cooking chamber 210 that has been activated reaches 100℃, it can be considered that the water or soup base in the cooking chamber 210 has been boiled, and the user's initial cooking requirements have been met. The user can also pay attention to the cooking status of each cooking chamber 210 and the heat status of each cooking chamber 210 can be known. Therefore, the user can be reminded to adjust the heat of each cooking chamber 210 independently. It can accurately determine that the current stage is not the cooking preheating stage, effectively preventing the dual hot pot control method of this application from making incorrect mode switching. It can also more intelligently identify whether the power mode of the corresponding heating module 110 needs to be switched from single-line linkage mode to synchronous adjustment mode, with a high degree of intelligence.

[0117] See Figure 8 In another embodiment, the method for determining the cooking preheating stage is as follows:

[0118] Step S501: After the main control unit receives the input signal from the user, proceed to step S502;

[0119] Step S502: Is it within the third time period? If yes, proceed to step S503; if no, proceed to step S504.

[0120] Step S503: If so, then the cooking preheating stage is underway;

[0121] Step S504: If not, then proceed to the cooking stage.

[0122] The advantage of this method is that after the user's input signal is transmitted or converted and input to the main control unit 120, timing begins. Within a preset third time period, the hot pot 100 is determined to be in the preheating stage; if the third time period is exceeded, the hot pot 100 is determined to be in the cooking stage. This method has lower hardware requirements, simpler program operation, is less prone to errors, and ensures that the hot pot 100 can exit the preheating stage. The user's input signal can be a function mode selection signal, a power adjustment signal for the switch, a power-on signal, etc., which can be selected according to design needs and is not limited here. Preferably, the third time period is 10-25 minutes, which meets the preheating requirements of most cooking modes and has wide applicability.

[0123] In some embodiments of this application, see Figure 1 The hot pot 100 also includes a switch 150. When the switch 150 is pressed, it switches between synchronous adjustment mode and single-line linkage mode. This allows the user to manually switch between the two modes. The advantage of the switch 150 is that it meets the user's power allocation needs, providing a method for users to choose the power mode independently. Users can rationally allocate power according to the cooking progress and the state of the ingredients, greatly improving cooking efficiency. Furthermore, it offers greater adaptability to different cooking scenarios. Appropriate power allocation can reduce the possibility of a heating module 110 operating continuously at high power for too long, extending the lifespan of the hot pot 100. In some embodiments, the user can be prompted by voice to press the switch 150 to switch modes in desired scenarios. Specifically, the switch 150 can be placed on the display panel of the hot pot 100 along with the menu selection button and adjustment switch 130 for convenient user operation. The switch 150 is designed so that users can manually switch power modes, making it convenient for users to choose the power distribution method according to cooking scenarios and needs.

[0124] In some embodiments of this application, the adjustment switch 130 is a rotary switch. Operating a rotary switch is more convenient and intuitive, allowing for faster adjustment by the user. The rotary switch easily achieves continuous stepless adjustment, enabling more precise power control of the heating module. Furthermore, stepless adjustment is more easily adapted to both single-row linkage mode and synchronous adjustment mode of the dual-compartment hot pot 100. The rotary switch is more durable, less prone to wear and aging compared to other adjustment switches 130, resulting in a longer service life. The user experience of rotating the rotary switch is more intuitive, allowing for better awareness of power adjustments. This enhances the monitoring capabilities of the dual-compartment hot pot control method provided in this application when the user needs to increase the power. The rotary switch provides a more stable control signal, and the time interval between rotation to the maximum power position and further increases in power is more accurate, making the determination of whether to switch from synchronous adjustment mode to single-row linkage mode more precise. The rotary switch is less prone to accidental activation, which is less likely to affect the judgment conditions of the hot pot control method provided in this application, and can reduce the occurrence of misoperation, making it more suitable for this type of hot pot 100.

[0125] In other embodiments of this application, the adjustment switch 130 may also be a capacitive touch switch or a physical button switch. The advantage of such switches is that users are less likely to adjust the power too high or too low, making it convenient for users to directly adjust to the power level they need. They can also achieve stepless adjustment, which is compatible with this type of hot pot 100. The hot pot control method disclosed in this application solves the problem of incorrect switching of power distribution mode caused by accidental activation of the power signal in synchronous adjustment mode, and the problem that the power of the heating module that starts first may be unexpectedly reduced in the single-line linkage mode during the cooking preheating stage.

[0126] In some embodiments of this application, a mode switching prompt tone is emitted after a power mode switch occurs to indicate the current power mode of the hot pot 100. This prompt tone promptly alerts the user that a mode switch has occurred, eliminating the need for user inspection or confirmation. This facilitates fulfilling the user's cooking needs, enhances operational convenience, and reduces the need for additional indicator lights, display interfaces, and other visual displays, thus lowering production costs. Furthermore, this solution improves safety. The prompt tone provides timely feedback to the user, preventing accidental operation and greatly enhancing the user experience and interactivity with the hot pot 100. For novice users, the prompt tone serves as a guide, reducing the learning curve.

[0127] In some embodiments of this application, the preset threshold is 1800-2600W, which is compatible with the load-bearing capacity of household sockets. Limiting this threshold range can prevent excessive power, ensure safety and stability in use, ensure the stable performance of each electrical component, and further guarantee the service life of the dual-compartment hot pot 100. Moreover, this threshold range can already meet the needs of daily use. For the synchronous adjustment mode, the maximum heating power of each heating module 110 can also be designed individually according to design requirements. In one embodiment, for example, when the preset threshold is 2200W and N=2, the preset sub-threshold can be set at 1000W. By leaving a margin, the safety requirements during mode switching are ensured. As long as the total power value of all heating modules 110 is less than or equal to the preset threshold, no restrictions are imposed here.

[0128] An embodiment of this application also provides a dual-compartment hot pot 100, see [link to relevant documentation]. Figure 1 The system also includes: a pot body 200, cooking chambers 210 located within the pot body, and a corresponding temperature sensor 140 located below each cooking chamber 210. The temperature sensor 140 is electrically connected to the main control unit 120. Each heating module 110 corresponds to one cooking chamber 210 and has at least one heating load. The main control unit 120 includes a processor and a memory. The memory stores programs or instructions, and the processor executes the programs or instructions in the memory to implement the aforementioned dual-compartment hot pot control method. Each heating module 110 has at least one heating load, and the power value of the heating module 110 referred to in this application is the sum of the power of all heating loads of each heating module 110.

[0129] In one embodiment, the cooking cavity 210 is an upward-opening cavity, and the heating module 110 can be disposed below, to the side or simultaneously with the cooking cavity 210, for heating the cooking cavity 210 and the food inside the cooking cavity 210. The heating module 110 can be a heating plate assembly or an electromagnetic coil assembly, etc.

[0130] The main control unit 120 is installed on the hot pot 100.
