Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and more specifically, to a mandarin duck hot pot and a control method thereof. Background Art

[0002] There is a kind of mandarin duck hot pot, which includes two heating modules, each of which has a corresponding adjustment switch. When using the mandarin duck hot pot, the user has the need to adjust the power of the corresponding heating module through one of the adjustment switches, and also has the need to adjust the power of the two heating modules at the same time through the adjustment switch. The existing mandarin duck hot pot can usually only meet one of the requirements. For the user, if only one requirement can be met, the steps of operating the adjustment switch become complicated, affecting the user experience and inconvenient operation.

[0003] In addition, while the mate hotpot can meet the above two needs at the same time, it brings a problem. It lacks the power mode that can automatically switch to meet the power regulation needs according to some scenarios. If it can only be switched manually, it will be inconvenient for users to operate, the user experience will be poor, and the learning cost will be high. If the power mode is automatically switched under inappropriate conditions, it will affect the performance of the mate hotpot. Summary of the invention

[0004] The purpose of the present application is to provide a double-flavored hot pot and a control method thereof, so as to solve the problem that the existing double-flavored hot pot cannot simultaneously satisfy the requirements of controlling the power of two heating modules independently and simultaneously by adjusting the switch, and to provide a double-flavored hot pot and a control method thereof which can automatically switch the power mode under appropriate conditions.

[0005] The embodiment of the present application is implemented as follows:

[0006] The present invention provides a control method for a double-flavored hot pot, which comprises 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 switch, wherein the total power value of the heating modules is less than or equal to a preset threshold value; the double-flavored hot pot is also provided with a synchronous adjustment mode and a single-line linkage mode; in the synchronous adjustment mode, any adjustment switch adjusts the power of the corresponding heating module, and the power of the other heating module increases or decreases accordingly; in the single-line linkage mode, when the total power value reaches a preset threshold value, the adjustment switch increases the power of the corresponding heating module, and the power of the other heating module decreases accordingly; the control method comprises: if the double-flavored 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 the heating module reaches a preset sub-threshold value, if the user inputs a first signal within a first time period, switching to the single-line linkage mode; if the double-flavored hot pot is in the single-line linkage mode, in the cooking preheating stage, judging whether the power of each heating module reaches a preset sub-threshold value, switching to the synchronous adjustment mode when the power of all heating modules reaches the preset sub-threshold value.

[0007] In a preferred embodiment, during the first time period, the Yuanyang Hotpot enters a first display mode, and the first display mode prompts the user through the display situation that the current mode is in a waiting-to-switch state; after entering the first display mode, the Yuanyang Hotpot ends the first display mode after obtaining the first signal or after the first time period.

[0008] In a preferred embodiment, the display condition is generated on the display panel of the yukan hotpot, and the display condition is a light strobe prompt, an indicator light constantly on prompt or a screen display prompt.

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

[0010] In a preferred embodiment, each of the heating modules is set corresponding to a cooking cavity; when the shabu-shabu hotpot is in a single-line linkage mode, if the power value of the corresponding heating module is greater than a preset sub-threshold and the temperature of the cooking cavity rises to a first preset limit temperature, the shabu-shabu hotpot is controlled to switch to a synchronous adjustment mode, and / or, if the power value of the corresponding heating module is less than or equal to the preset sub-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 reaches a preset sub-threshold further includes: after starting the second heating module, within a second time period, when the power of all heating modules reaches a preset sub-threshold, switching to a synchronous adjustment mode.

[0012] In a preferred embodiment, the shabu-shabu hotpot also includes two cooking cavities corresponding to the two heating modules, and the method for judging the cooking preheating stage is: judging whether the temperatures of the two cooking cavities are less than or equal to a preset limit temperature; if so, it is in the cooking preheating stage; if not, it is in the cooking stage; or, when the main control unit receives an input signal from the user, the shabu-shabu hotpot is in the cooking preheating stage within a third time period.

[0013] In a preferred embodiment, the shuangyan hotpot further comprises a switching switch, and after the user inputs the instruction through the switching switch, the synchronous adjustment mode and the single-line linkage mode are manually switched.

[0014] In a preferred embodiment, during the cooking process of the shabu-shabu hotpot, the power value of the heating module is adjusted in a continuous manner, and the adjustment switch is a knob switch, a capacitive touch switch or a physical button switch.

[0015] On the other hand, another embodiment of the present application proposes a shabu-shabu hot pot, which also includes: a pot body, including two cooking cavities corresponding to the two heating modules, and a corresponding temperature sensor is provided under the pot body corresponding to each cooking cavity, and the temperature sensor is electrically connected to the main control unit, and the heating module has at least one heating load; the main control unit includes a processor and a memory, the memory stores a program, and the processor implements the shabu-shabu 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 the synchronous adjustment mode and the single-line linkage mode in the mate hot pot, the problem that the existing mate hot pot cannot simultaneously satisfy the requirements of individual control of the adjustment switch and simultaneous control of the power of the two heating modules is solved. The user can adjust the two heating modules conveniently, and the user experience is improved.

[0018] In addition, the shabu-shabu hotpot and its control method disclosed in the present application provide a shabu-shabu hotpot and its control method that can automatically switch power modes under appropriate conditions. When in the synchronous adjustment mode, after the user increases the power of any heating module through the adjustment switch, if the power of the heating module reaches the preset sub-threshold, within the first time period, if the user inputs a first signal, it switches to the single-line linkage mode, and the shabu-shabu hotpot is at the boundary of the maximum power of the synchronous adjustment mode, the main control unit needs to obtain the first signal for the first time period through any adjustment switch to output the power increase signal before performing the mode switching operation, which solves the problem of incorrect mode switching caused by the power increase signal generated by misoperation at the boundary of the maximum power value of the shabu-shabu hotpot in the synchronous adjustment mode, thereby ensuring the performance of the shabu-shabu hotpot and improving the user experience;

[0019] When in single-line linkage mode, during the cooking preheating stage, it is determined whether the power of each heating module has reached the preset sub-threshold. When the power of all heating modules reaches the preset sub-threshold, it is switched to the synchronous adjustment mode. At this time, the heating modules required by the user to work at high power have been switched to the synchronous adjustment mode of synchronously controlling power. The user can adjust the adjustment switch of one of the heating modules to synchronously change the power value of the other heating module. The power value of the other heating module will not be reduced or even reduced to 0. The heating module required to work at a higher power will be automatically switched to the synchronous adjustment mode. The cooking appliance has a high degree of intelligence, which greatly reduces the user's operation and judgment, reduces the learning cost of the device, and improves the user's experience. The problem that the power value of the heating module adjusted first is lower than the user's expectation when the two heating modules are adjusted to the high-power gear in succession due to the fact that the mandarin duck hot pot is in the mode of individually controlling the power of the heating modules during the cooking preheating stage is solved.

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

[0037] It should be noted in advance that the following single-line linkage mode and synchronous adjustment mode are both one of the power modes of the mandarin duck hot pot. For the power signal output by the main control unit 120, when the output power signal is output 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 technology in this field and will not be elaborated below.

[0038] As described in the foregoing background art, the existing mandarin duck hot pot including two heating modules cannot meet the requirements of separately controlling the power of the corresponding heating module by adjusting the switch and simultaneously controlling the power of the two heating modules by adjusting the switch. The applicable scenarios are few, and it is inconvenient for users to adjust the power, so the user experience is poor.

[0039] The mandarin duck hot pot 100 provided by the embodiment of this application. See Figure 1, the mandarin duck hot pot 100 includes a heating module 110 and a main control unit 120, each heating module 110 is correspondingly provided with an adjustment switch 130, and the main control unit 120 is electrically connected to the heating module 110 and the adjustment switch 130. The operation signal input by the user is processed by the main control unit 120 and input to the heating module 110 so that it performs the corresponding operation. For example, the user inputs a signal for adjusting the power through the adjustment switch 130. After receiving the signal, the main control unit 120 outputs a corresponding power signal to the corresponding heating module 110, so that the power value of the corresponding heating module 110 is adjusted to the size required by the user. In one embodiment, the heating module 110 adopts an electromagnetic heating module, and its heating unit includes a control unit and a coil unit. The aforementioned power signal is received by the control unit to control the corresponding heating unit to work at a limited power value. In other embodiments, the heating module 110 can also be a heating plate assembly with adjustable power.

[0040] The main control unit 120 is set on the yucca hotpot 100, and 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] At least two power modes are provided in the control program of the main control unit 120, that is, the mandarin duck hot pot 100 is also provided with at least two power modes. In one embodiment of the present application, it includes a single-line linkage mode for individually controlling the power of the heating module and a synchronous adjustment mode for simultaneously controlling the power of two heating modules. The two power modes can be manually or intelligently selected to meet the needs of the current cooking scene. The applicable scenarios are wide and the user experience is good. When the mandarin duck hot pot 100 is just turned on, the mandarin duck hot pot 100 can be in synchronous adjustment mode or single-line linkage mode, or it can be set according to actual needs. It needs to be restricted that the total power value of all heating modules 110 is less than or equal to the preset threshold.

[0042] In the synchronous adjustment mode, any adjustment switch 130 adjusts the power of the corresponding heating module 110, and the power of the other heating module 110 increases or decreases accordingly; in the synchronous adjustment mode, the power of the two heating modules 110 can be changed at the same time through any adjustment switch 130, that is, the power values ​​of the two heating modules 110 are adjusted to increase or decrease at the same time, so when the user needs to adjust the power of the two heating modules 110, the power values ​​of the two heating modules 110 can be changed by adjusting one adjustment switch 130. In one embodiment, the change amount of the power value of the two heating modules 110 is equal. For example, when the power value of the corresponding heating module is increased by 100W by adjusting any adjustment switch 130, the power value of the other heating module 110 is also increased by 100W, and so on. This can better meet the user's intention to adjust the power of the two heating modules 100 at the same time through one adjustment switch 130, and the change amount is controllable and the adjustment is rapid. In another embodiment, when the duo hot pot 100 is in the synchronous adjustment mode, the power of the two heating modules 110 is completely equal and adjusted at the same time, so that the user can heat multiple cooking cavities evenly. For example, in the hot pot scenario, each cooking cavity is initially added with an appropriate amount of water or soup base. At this time, the liquid in all cooking cavities needs to be boiled. To ensure cooking efficiency, the power of each heating module is quickly and evenly increased through the synchronous adjustment mode, thereby improving the user experience. One-button heating is more convenient for this cooking scenario.

[0043] In the synchronous adjustment mode, the power of each heating module 110 is less than or equal to the preset sub-threshold, that is, the maximum power value of each heating module 110 is the preset sub-threshold. When the power value of the heating module 110 has reached the preset sub-threshold, even if the user inputs a power increase 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 power increase signal, or it can not increase 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 the two heating modules 110 are both the preset sub-threshold, the total power value of the heating modules 110 will not exceed the preset threshold, so that the performance of the mandarin duck hot pot 100 can be fully exerted without causing 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 the corresponding heating module 110, thereby realizing a separately controlled power mode. For example, when the yukan hot pot 100 is used as a single pot or the heating power of the cooking cavity of one of the pots needs to be adjusted, this mode can be well adapted to such cooking scenarios. The difference is that in the single-row linkage mode, in addition to each adjustment switch 130 individually controlling the power of its corresponding heating module 110, when the total power value of the heating module 110 reaches a preset threshold, if the adjustment switch 130 adjusts the power value of the corresponding heating module 110 to increase, and the power value of another heating module 110 is not 0, 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 reduced. At this time, the power increase signal output by the adjustment switch 130 is invalid, and the power of the corresponding heating module 110 will not be increased.

[0045] When the Yuanyang Hotpot is in the synchronous adjustment mode and the heating module of the Yuanyang Hotpot is at the boundary of the maximum power in this mode, if it directly switches to the single-line linkage mode after receiving the power increase signal, it is impossible to avoid the problem of incorrect mode switching caused by the power increase signal due to misoperation, which will affect the performance of the Yuanyang Hotpot and reduce the user experience.

[0046] For this scenario, the double-stranded hot pot control method disclosed in the present application provides a scheme 1: if the double-stranded hot pot 100 is in the synchronous adjustment mode, after the user increases the power of any heating module 110 by adjusting the switch 130, if the power of the heating module 110 reaches the preset sub-threshold, if the user inputs the first signal within the first time period, it switches to the single-line linkage mode; in this way, when the adjustment switch 130 adjusts to increase the power of the heating module 110 that has reached the preset sub-threshold, through the 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 adjusted heating module 110 power to be greater than the preset sub-threshold. At this time, the double-stranded hot pot 100 needs to be switched from the synchronous adjustment mode to the single-line linkage mode so that the adjusted heating module 110 power can be greater than the preset sub-threshold. Through this scheme, the problem of incorrect mode switching caused by misoperation when the user increases the power of any heating module 110 by adjusting the switch 130 for the first time can be avoided.

[0047] In another scenario, when the Yuanyang Hotpot 100 is first used and is in single-line linkage mode, the user may require multiple heating modules 110 to work at their maximum power, and the power of two heating modules 110 is adjusted to a high-power position in succession. As a result, the power value of the first adjusted heating module 110 is accidentally reduced or even reduced to 0 without the user's knowledge, thereby affecting the user's experience and causing a high learning cost for the Yuanyang Hotpot 100.

[0048] For this other scenario, the control method of the mandarin duck hot pot disclosed in the present application provides a second solution: if the mandarin duck hot pot 100 is in the single-line linkage mode, in the cooking preheating stage, it is determined whether the power of each heating module 110 reaches the preset sub-threshold, and when the power of all heating modules 110 reaches the preset sub-threshold, it is switched to the synchronous adjustment mode;

[0049] This application divides the working process of the mandarin duck hot pot 100 into a cooking preheating stage and a cooking stage. In the cooking preheating stage, usually when the user just starts cooking, the cooking cavity temperature or heating time of the mandarin duck hot pot 100 has not yet reached the requirements. Generally, in this stage, the user needs to adjust the activated heating module 110 to the maximum power it can reach or even the maximum power to achieve the requirements of rapid heating or preheating. When entering the cooking stage, it can be considered that the user has preheated the mandarin duck hot pot 100 or the user can clearly identify the working conditions of each heating module 110, and can control the power value of each heating module 110 more independently.

[0050] Through solution 2 for another scenario, when judging whether the power of each heating module 110 reaches the preset sub-threshold during the cooking preheating stage, when the power of all heating modules reaches the preset sub-threshold, it can be considered that the user wishes to adjust the two activated heating modules 110 to a larger power value or a maximum power value in the current state. In order to prevent the power value of the first heating module 110 adjusted to high power from being accidentally reduced or even reduced to 0 due to the fact that the double-row linkage mode of the double-row hot pot 100 is in a single-line linkage mode, to solve this problem that does not conform to the user's intention and to facilitate the user to make subsequent adjustments, the double-row hot pot 100 is switched to a synchronous adjustment mode, so that even if the user continues to increase the power value of the second adjusted heating module 110 through the adjustment switch 130 input, the power of the first adjusted heating module 110 will not be reduced, which effectively solves the aforementioned problem. In addition, due to the intelligent automatic switching, the user's operation and judgment are greatly reduced, the learning cost of the double-row hot pot 100 is reduced, and the user's experience is improved.

[0051] Combining the above two schemes, the mandarin duck hot pot control method disclosed in the present application can solve the problem that in the operation process of the mandarin duck hot pot 100 equipped with synchronous adjustment mode and single-line linkage mode, manual switching of power modes is required in some scenarios, resulting in poor user experience and high learning cost. In addition, intelligent automatic switching can make the mandarin duck hot pot 100 more intelligent and ensure its working performance.

[0052] See also Figure 2 , shows a flow chart of an embodiment of scheme 1 of the mandarin duck hot pot control method disclosed in the present application.

[0053] See also Figure 2 The control method of the above scheme 1 specifically includes:

[0054] Step S101: When the yukan hotpot 100 is in a synchronous adjustment mode, in which the power values ​​of the heating modules 110 change simultaneously, and the power value of a single heating module 110 is less than or equal to a preset threshold value, wherein, in some embodiments, the preset threshold value is equal to half of the preset threshold value, and in other embodiments, the preset threshold value may also be other values, as long as the total power of the two heating modules is less than the preset threshold value when they work according to the preset threshold values; then enter step S102.

[0055] Step S102: If the power value of the heating module adjusted by any adjustment switch is equal to the preset threshold value; if so, proceed to step S103; if not, proceed to step S104.

[0056] Step S103: After the regulating switch 130 outputs a power increase signal; the power increase signal here is usually output by the regulating switch 130, and the main control unit 120 receives and processes the signal. This method is a conventional processing method in this field and will not be described in detail here. It can be understood that in the synchronous regulation mode, since the power values ​​of each heating module 110 are adjusted at the same time, when the power value of the heating module 110 whose power is adjusted to increase has reached the preset threshold value, in the synchronous regulation mode, if the regulating switch 130 continues to output a power increase signal, the heating power of the heating module 110 whose power is adjusted to increase will not continue to increase, but if the mandarin duck hot pot 100 switches to the single-line linkage mode in response to the power increase signal, the power value of the heating module 110 whose power is adjusted to increase will also be increased according to the power increase signal; then enter step S105.

[0057] Step S104: Continue to operate according to the current working condition of the Yuanyang Hotpot 100.

[0058] Step S105: Determine whether the main control unit 120 obtains the first signal within the first time period, if so, proceed to step S106; if not, proceed to step S107.

[0059] In some embodiments, the first signal is a power increase signal, that is, the power increase signal output again by the adjustment switch 130. The power increase signal is used as a judgment condition to determine whether to switch to the single-line linkage mode. The advantage is that the user's strong intention to increase power is more accurately recognized, so the user continues to input the power increase signal quickly, and the response performance of the mandarin duck hot pot 100 is better, and the user experience is good. In other embodiments, the first signal can also be a confirmation signal or a start signal, etc., which requires the user to confirm the operation. For example, the user sends a confirmation signal by pressing the confirmation button located on the adjustment switch 130, or presses the start button on the mandarin duck hot pot 100 to send a start signal to confirm that the user does need to switch to the single-line linkage mode. For the user, the operation feedback is stronger, and the user experience is better.

[0060] Step S106: switching to a 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 a preset threshold, the power values ​​of the remaining heating modules 110 are correspondingly reduced;

[0061] In the synchronous adjustment mode, when the power value of the heating module 110 whose power is adjusted to increase has reached the preset threshold value, the main control unit 120 receives the first signal within the first duration of the power increase signal output by the adjustment switch 130. It can be considered that the power value of the corresponding heating module 110 needs to continue to increase upward at this time, so the synchronous adjustment mode is switched to the single-line linkage mode. Since in the single-line linkage mode, the power upper limit of a single heating module 110 can reach the preset threshold value, when 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 value, 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 value. Therefore, although this mode is that an adjustment switch 130 controls the power value of a heating module 110 alone, when a certain adjustment switch 130 outputs a signal to increase the power, it may also cause the power value of the remaining heating modules 110 to decrease. Therefore, the power value of each heating module 110 is changed in linkage, specifically, the power value of two heating modules 110 is changed in linkage;

[0062] In some embodiments, after switching to the 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 user's secondary operation. In other embodiments, the 2-way hot pot 100 may not respond to the previous power increase signal and wait for the user to input the power adjustment signal again, which can be set according to the design needs.

[0063] Step S107: If not, continue to operate according to the current working condition of the Yuanyang Hotpot 100.

[0064] In the double-row hot pot 100 with two heating modules 110 that carries both the synchronous adjustment mode and the single-row linkage mode, two different power modes can be switched. However, there is a problem: in the synchronous adjustment mode, if the power value of each heating module 110 reaches the preset sub-threshold value, when the user outputs a power increase signal to the main control unit 120 through a certain adjustment switch 130, if the mode is directly switched to the single-row linkage mode at this time, so that the power value of the corresponding heating module 110 can exceed the limit value of the preset sub-threshold value, it is impossible to avoid the situation that the power increase signal is generated by an erroneous operation such as an accidental touch. In this case, if the mode is directly switched, the normal cooking of the double-row hot pot 100 will be affected, and the performance of the double-row hot pot 100 will be reduced. The user also needs to discover this situation in time and manually correct this problem, which brings inconvenience to the user and reduces the user experience.

[0065] The control method of the above scheme 1 disclosed in the present application can solve the problem of wrong switching of the power distribution mode caused by misoperation. The working principle is: when the mandarin duck hot pot 100 is in the synchronous adjustment mode, when the power value of the heating module 110 adjusted to increase the power has reached the preset sub-threshold value, it can be known that in this mode, the power value of the heating module 110 adjusted to increase the power has reached the boundary value, at this time, if the adjustment switch 130 outputs the power increase signal or the main control unit 120 obtains the power increase signal, it will be judged whether the main control unit 120 obtains the first signal within the first time length, if the first signal is obtained, it can be considered that the user or the main control unit needs the corresponding power value of the heating module 110 adjusted to increase the power to exceed the preset sub-threshold value, and the current power mode does not meet the requirements, then switch to the single-line linkage mode to meet the power adjustment requirements, in addition, if necessary, the power values ​​of the remaining 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] In the scheme 1 of the control method of the mandarin duck hot pot of the present application, when the boundary condition of the maximum power of the synchronous adjustment mode is reached, after the adjustment switch 130 outputs the power increase signal or the main control unit 120 obtains the power increase signal, it is determined whether the main control unit 120 receives the first signal within a reasonable first time length before the mode switching operation is performed, which effectively solves the problem that the power increase signal received for the first time in this boundary situation is generated by an erroneous operation, but the mandarin duck hot pot 100 directly switches to the single-line linkage mode. Such a problem not only brings inconvenience to the user, but also affects the cooking performance of the mandarin duck hot pot 100 being used. The scheme 1 avoids the situation of false touch and ensures that the switching action when it is necessary to switch to the single-line linkage mode is performed. Preferably, the first time length is 0.5-10s, and this range can reasonably wait for the user to perform the operation that can generate the first signal, so as not to wait too long and affect the normal operation of the mandarin duck hot pot 100.

[0067] In some embodiments of scheme 1 of the present application, at the same time as step S105, the yuanyang hotpot 100 enters the first display mode, and the first display mode prompts the user through the display situation that the current mode is in the waiting state to be switched.

[0068] In the process of step S105, the mandarin duck hot pot 100 is equivalent to entering a monitoring state with a waiting time of the first time length. When the first signal is obtained, the mode will be switched. However, there is a problem at this time. The user may not be clear about the information that the mandarin duck hot pot 100 is in this monitoring state, which may cause the user to not know that the operation of generating the first signal within the first time length can make the mandarin duck hot pot 100 directly switch to the single-line linkage mode. To solve this problem, give full play to the advantages of the control method of the scheme one disclosed in this application. This embodiment adds a first display mode within the first time length, and prompts the current mode to be switched through the set display situation, improves the user's perception of this monitoring state, and ensures that the user knows that the current mode may need to be switched. The operation of switching to the single-line linkage mode by generating the first signal can be written in the user manual, the shell of the mandarin duck hot pot 100, or by voice informing the user when the mode is in the state of waiting to be switched. At this time, the user's experience of using the mandarin duck hot pot 100 is improved, and the mandarin duck hot pot 100 using the control method is highly intelligent.

[0069] For the first display mode solution, it is necessary to stop the first display mode under given conditions, see Figure 3 , the present application provides a control method for ending the first display mode:

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

[0071] Step S202: After the first signal is acquired or the first time period has passed, proceed to step S203;

[0072] Step S203: Yuanyang Hotpot 100 ends the first display mode.

[0073] The control method for ending the first display mode has the advantage of stopping the first display mode in time when the mode waiting to be switched state has ended, ensuring that other display modes of the Yuanyang Hotpot 100 can work normally.

[0074] Specifically, in some embodiments, the display occurs on the display panel of the simmering hot pot 100, and the display includes but is not limited to prompts through strobing lights, prompts through indicator lights that are always on, or prompts through screen displays. This type of method uses an obvious display method to prompt the current mode to be switched, and the user can easily notice the display and make operations in time, avoiding the user from not knowing and not making operations to meet their cooking needs. This type of display is a common technical means in the field of electrical appliances, and will not be repeated or limited here. In other embodiments, the display can also be generated at other locations of the simmering hot pot 100, or the display can also be a simple voice prompt, as long as it can serve as a prompt.

[0075] In some embodiments of the present application, after the shabu-shabu hot pot 100 switches to the single-row linkage mode, the shabu-shabu hot pot 100 may have different power values ​​for different cooking chambers 210, and it may be considered to add a safety consideration control method for the heating modules 110 with different power values. In one embodiment, the safety consideration control method includes:

[0076] When the shabu-shabu hotpot 100 is in single-line linkage mode, if the power value of the corresponding heating module 110 is greater than the preset threshold value, the temperature of the cooking cavity 210 rises to the first preset limit temperature; if so, the shabu-shabu hotpot 100 is controlled to switch to the synchronous adjustment mode; if not, it continues to work.

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

[0078] When the yukan hotpot 100 is in single-line linkage mode, if the power value of the corresponding heating module 110 is less than or equal to the preset threshold value, the temperature of the cooking cavity 210 rises to the second preset limit temperature; if so, the corresponding heating module 110 is controlled to stop heating; if not, it continues to work.

[0079] The above two control methods for safety considerations can be applied to the double - boiler hot pot 100 simultaneously, and have different application scenarios for different situations. For example, if the heating power of the cooking cavity 210 is greater than the preset sub - threshold, when the temperature of the cooking cavity 210 rises to a certain extent, it can indicate that the temperature of the cooking cavity 210 has reached the required temperature. For example, at the beginning stage of boiling the hot pot, it can indicate that the water has boiled. At this time, there is no need for high - power heating, and it can be switched back to the synchronous adjustment mode. Because in the synchronous adjustment mode, the maximum power value of a single heating module 110 will be further limited below the preset sub - threshold, so as to reduce potential safety problems under high power. Another example is that if the heating power of the cooking cavity 210 is less than the preset sub - threshold, and at this time if the temperature of the cooking cavity 210 also rises to a certain extent, it may indicate that the liquid here has been exhausted, so a large temperature rise has occurred even under low power. At this time, the heating module 110 of this cooking cavity 210 can be stopped to further ensure the safe use of the double - boiler hot pot 100. Preferably, the second preset limit temperature is less than the first preset limit temperature. For the heating module 110 with a smaller power, the temperature rise degree of its cooking cavity 210 may be smaller. Therefore, the second preset limit temperature with a smaller temperature value can be specifically used as the determination condition.

[0080] See Figure 4 , which shows a schematic flow chart of an embodiment of the second solution of the double - boiler hot pot control method disclosed in the present application.

[0081] The following description of the second solution includes the case where the number of heating modules 110 is greater than or equal to two. The case of 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 double - boiler hot pot 100 where multiple heating modules 110 are in the synchronous adjustment mode, but there are heating modules 110 in the single - row linkage mode. Then the double - boiler hot pot 100 as a whole is in the single - row linkage mode.

[0082] See Figure 4 , the control method of the above - mentioned second solution specifically includes:

[0083] Step S301: Determine whether it is in the cooking pre - heating stage: if so, go to step S302; if not, go to step S303.

[0084] Step S302: Determine whether there is a started heating module in the single - row linkage mode: if so, go to step S304; if not, go to step S305.

[0085] It is understandable that only when the heating module 110 is activated, the change of its power value will affect the power of other activated heating modules 110. Therefore, in the scheme 2 of the control method of the double-flavored hot pot disclosed in the present application, when the double-flavored hot pot 100 has at least two heating modules 110, the control method of scheme 2 will be run when at least two heating modules 110 are activated, but no restriction is imposed on the heating modules 110 that are not activated.

[0086] It should be noted that there is a boundary condition. If the aforementioned power signal causes the power value of a single heating module 110 to exceed the preset threshold value or causes the total power value of the corresponding heating module 110 to exceed the preset threshold value, 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 value. In this way, the use safety of the mandarin duck hot pot 100 can be guaranteed. In one embodiment, the number of heating modules 110 is greater than or equal to three. There may be one or more common heating modules that are in the synchronous adjustment mode. The power values ​​of the common heating modules are changed at the same time. Preferably, the power values ​​of the various heating modules 110 of the common heating modules are changed synchronously and are equal. Therefore, when there are still heating modules 110 in the single-row linkage mode, the power value of the common heating module is increased or decreased synchronously. Therefore, the power value of the corresponding heating module also includes the sum of the power values ​​of the common heating modules that are increased together. The common heating module and other non-common heating modules are in the power mode of the single-row linkage mode as a whole. It can be understood that as long as there is a heating module 110 that is still in the single-row linkage mode, the power distribution of the shabu-shabu hotpot 100 is generally in the power mode of the single-row linkage mode.

[0087] Step S303: If not, it is determined that the Yuanyang Hotpot 100 is in the cooking stage, and the Yuanyang Hotpot 100 continues to operate according to the current power mode.

[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 the preset threshold value; wherein the preset threshold value is 1 / N times the preset threshold value, N≥2. It can be known that, in the single-line linkage mode, when the power value of a certain heating module 110 is increased so that it is about to exceed the preset threshold value, and the power values ​​of other activated heating modules 110 are already equal to the preset threshold value, and continuing to increase the power value of the certain heating module 110 will cause the total power value to exceed the preset threshold value, the main control unit 120 will control the power values ​​of 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 the preset threshold value, and according to the fact that the power values ​​of other activated heating modules 110 in the cooking preheating stage have been increased to the preset sub-threshold value, it can be known that the user does not want the power values ​​of the remaining heating modules 110 to be reduced. Therefore, by using this condition as the basis for whether all activated heating modules 110 need to be switched to the synchronous adjustment mode, it can be prevented that in the cooking preheating stage, when the user wants multiple heating modules 110 to work at the maximum power that can be achieved, the power value of the heating module 110 whose power value has not been increased is reduced or even reduced to 0. Since the control method has the aforementioned effect only when two heating modules 110 are activated, N≥2. The advantage of setting the size of the preset sub-threshold value equal to 1 / N times the preset threshold value is that the user's intention to adjust the specified heating module 110 to a higher power level can be accurately identified; if so, enter step S306; if not, enter step S307.

[0089] Step S305: If not, continue to operate according to the current power mode of the Yuanyang Hotpot 100.

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

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

[0092] It can be understood that controlling all activated heating modules 110 to switch to the synchronous adjustment mode is to bind the currently activated heating modules 110 together and then switch to the synchronous adjustment mode. The heating modules 110 that have not been activated and the heating modules 110 that will be activated later will not be bound and switched. For example, if a heating module 110 in the single-line linkage mode is activated later, its power adjustment will be independently controlled by its corresponding adjustment switch 130, and it and the heating modules 110 that are bound together and switched to the synchronous adjustment mode are in the single-line linkage mode as a whole. At this time, the total power value of the heating modules 110 that are bound together in the synchronous adjustment mode changes in linkage with the total power value of the heating modules 110 in the single-line linkage mode, and the sum of the two does not exceed the preset threshold. Among them, the heating modules 110 that are bound together in the synchronous adjustment mode, their respective corresponding adjustment switches 130 can simultaneously adjust the power values ​​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 according to the current power mode of the Yuanyang Hotpot 100.

[0094] Through the control method of the above scheme 2, the existing double-stranded hot pot 100 with multiple heating modules 110 can solve the problem that when the power value of the heating module 110 is controlled separately during the cooking preheating stage, the single-line linkage mode will cause the power value of the unregulated heating module to be accidentally reduced or even reduced to 0 when the user wants multiple heating modules 110 to work at high power. Through the above scheme, when the power of all activated heating modules 110 is equal to the preset sub-threshold value during the cooking preheating stage, it can be considered that the user wants to adjust the corresponding activated heating module 110 to a larger power value or a maximum power value in the current state. In order to prevent the problem that the power value of the unregulated heating module is accidentally reduced or even reduced to 0 due to the existence of the heating module 110 in the single-line linkage mode and to facilitate the user to make subsequent adjustments, the corresponding activated heating module 110 is bound and switched to the synchronous adjustment mode, which effectively solves the above-mentioned problem. In addition, due to the intelligent automatic switching, the user's operation and judgment are greatly reduced, the learning cost of the double-stranded hot pot 100 is reduced, and the user's experience is improved.

[0095] It can be known that the power distribution method parameters of the shabu shabu hotpot 100 are all processed by the main control unit 120, so the main control unit 120 can obtain the power status of each heating module 110 in real time, so the main control unit 120 can promptly make a judgment on whether the power value of the N activated heating modules reaches the preset threshold value. Therefore, after reading the specific implementation methods provided in this application, those skilled in the art can make the judgment of step S304 by changing the power of each heating module 110 or making a cyclic judgment, thereby realizing the shabu shabu control method of this application in this type of shabu shabu hotpot 100.

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

[0097] For step S304, in some other embodiments, see Figure 5 , and further includes:

[0098] Step S304': After the Nth heating module 110 is activated, within the 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 sub-threshold value; 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 its power value to the preset sub-threshold value within the second time period after a certain heating module 110 is activated, it can be considered that it is actually unnecessary to heat all the activated heating modules 110 at the corresponding high power that can be achieved. Therefore, if the waiting time exceeds the second time period, the mandarin duck hot pot 100 is controlled to continue to work in the original power mode. The setting of the second time period can reasonably wait for the user's intention to switch all the activated heating modules 110 to the synchronous adjustment mode, and solve the problem that the working performance of the mandarin duck hot pot 100 is affected by the condition of the unlimited judgment step S304' after a certain heating module 110 is activated. The detection of the second duration may be implemented by setting a timer in the main control unit 120, which is a conventional technical means in the art and will not be elaborated herein.

[0099] Specifically, in the shabu-shabu hot pot 100 with two heating modules 110, step S304' is to switch to the synchronous adjustment mode after starting the second heating module 110, within the second time period, when the power of all heating modules 110 reaches a preset threshold value. For the shabu-shabu hot pot 100 with two heating modules 110, the control method is executed after starting the second heating module 110. The shabu-shabu hot pot control method of scheme two is not prone to errors, thereby ensuring the normal operation of the function.

[0100] For step S304', in another embodiment, the preset sub-threshold value decreases as the number of activated heating modules 110 increases, so the second duration can be reduced as the number of activated heating modules 110 increases. As the number of activated heating modules 110 increases, the preset sub-threshold value will decrease. According to the user's input, the time required for the main control unit 120 to output a power signal that makes the power value of the currently activated heating module 110 the preset sub-threshold value may also decrease. Therefore, reducing the second duration as the number of activated heating modules 110 increases will be more in line with the needs of actual scenarios, and the control method of the second scheme of the present application will be more accurate. Preferably, the value range of the second duration is 1s-5min. This value range can meet the time interval for the user to adjust the power of the activated heating module 110 to the preset sub-threshold value in most scenarios, and is suitable for a wide range of scenarios.

[0101] During the operation of the shabu-shabu hotpot 100, the power value of the heating module 100 is adjusted in a continuous manner, which is a conventional technical means in the art and will not be elaborated here.

[0102] Regarding the question of under what operation the heating module 110 is started, a brief explanation is given below. When a certain heating module 110 has not been started, 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 is not started, it will be started directly. That is, in this embodiment, the main control unit 120 continuously adjusts the power value of the heating module 120, and the power value of the heating module 110 changes continuously from 0 to the maximum power value, which is easy to implement step S304 or step S304'. In the field of double-flavored 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 and transmits it to the main control unit 120, 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 input by 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 first and then the power setting will be performed. Therefore, in this embodiment, the purpose of step S304 or step S304' can still be achieved, but at this time, step S304" is obtained 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 the preset threshold value. This embodiment is equivalent to performing step S304' on the N heating modules 110 to be started, and can also achieve the problem to be solved by the present application.

[0104] For step S304, in some other embodiments, see Figure 6 , and further includes:

[0105] After step S302, if yes, 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 first N-1 activated heating modules 110 are in the synchronous adjustment mode together; if so, proceed to step S304b; if not, 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 value; if so, it proceeds to step S306; if not, it proceeds to step S307;

[0108] Step S304c: If not, continue to operate according to the current power mode of the Yuanyang Hotpot 100;

[0109] After the second heating module 110 is started, step S304a directly enters step S304b; or after the third and more heating modules 110 are started, it is determined whether the heating modules 110 started earlier than the heating module 110 are in the synchronous adjustment mode together;

[0110] If the first N-1 activated heating modules 110 are already in the synchronous adjustment mode together, 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, and the Nth activated heating module 110 is in the single-line linkage mode, and is controlled separately by its corresponding adjustment switch 130. Therefore, when the power value of the Nth activated heating module 110 increases to the preset threshold value, 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] In order to prevent the power values ​​of the first N-1 activated heating modules from being reduced due to the user's excessive increase in power, the present application enters step S304b after the judgment in step S304a is yes. Step S304b only judges whether the power value of the Nth activated heating module 110 is equal to the preset threshold value, without obtaining the power values ​​of all activated heating modules 110 for judgment, so that the program execution is faster, simpler, and less prone to errors, ensuring the execution of the control method of the second solution of the present application and the performance of the mandarin duck hot pot 100. After the judgment in step S304b is no, it enters step S304c, without subsequent judgment, and directly maintains the current power mode of the mandarin duck hot pot 100, so that the program is more reasonable and reduces waiting time.

[0112] The following is a detailed description of the judgment conditions for the cooking preheating stage. Figure 1 The double-flavored hot pot 100 further includes at least two cooking chambers 210, and each heating module 110 is disposed corresponding to the cooking chamber 210. Figure 7 In one embodiment, the method for determining the cooking preheating stage is:

[0113] Step S401: determine whether the temperature of the cooking chamber corresponding to all activated heating modules is less than or equal to a preset limit temperature; if so, proceed to step S402; if not, proceed to step S403;

[0114] Step S402: If yes, it is in the cooking preheating stage;

[0115] Step S403: If not, it is in the cooking stage.

[0116] The shabu-shabu hotpot control method of the present application is applied to a shabu-shabu hotpot 100 including two heating modules 110. Therefore, in the cooking preheating stage, the user will start the corresponding heating module 110 for the cooking cavity 210 that needs to be heated. To ensure that the shabu-shabu hotpot 100 can be used accurately, it is only necessary to judge the cooking cavity temperature corresponding to the started heating module 110. The advantage of this judgment method is that the temperature of the cooking cavity 210 can be used to more accurately judge whether the current temperature conditions meet the cooking requirements. For example, if it is a boiling water or hot pot mode, the boiling point of water or soup base is around 100°C, and the preset limit temperature is set to 100°C. Then, if the temperature of any cooking cavity in all the activated cooking cavities 210 reaches 100°C, it can be considered that the water or soup base in the cooking cavity 210 has been boiled, and it can be considered that the user's initial cooking requirements have been met. The user can already pay attention to the cooking status of each cooking cavity 210, and the firepower status of each cooking cavity 210 can also be known. Therefore, the user can be reminded to adjust the firepower of each cooking cavity 210 independently, and it can be accurately considered that the current stage does not belong to the cooking preheating stage, which effectively prevents the double-row hot pot control method of the present application from performing erroneous mode switching, and more intelligently identifies whether it is necessary to switch the power mode of the corresponding heating module 110 from the single-line linkage mode to the synchronous adjustment mode, with a high degree of intelligence.

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

[0118] Step S501: When the main control unit receives an input signal from the user, it proceeds 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 yes, it is in the cooking preheating stage;

[0121] Step S504: If not, it is in the cooking stage.

[0122] The advantage of the judgment method of this embodiment is that after the user's input signal is transmitted or converted and input to the main control unit 120, the timing starts. Within the preset third duration, it is determined that the mandarin duck hot pot 100 is in the cooking preheating stage. If it exceeds the third duration, it is determined that the mandarin duck hot pot 100 is in the cooking stage. Such judgment has low hardware requirements, simple program operation, and is not prone to errors, and it is ensured that the mandarin duck hot pot 100 can be out of the cooking preheating stage. The user's input signal can be a selection signal for a function mode, a power adjustment signal of an adjustment switch, a power-on signal, etc., which can be selected according to the design needs, and is not limited here. Preferably, the third duration is 10-25 minutes, which meets the cooking preheating requirements of most cooking modes and is applicable to a wide range of scenarios.

[0123] In some embodiments of the present application, see Figure 1 , the mandarin duck hot pot 100 also includes a switch 150. When the switch 150 is pressed, the synchronous adjustment mode and the single-line linkage mode are switched. That is, through the setting of the switch 150, the user can manually switch between the two modes. The advantage of the switch 150 is that it can meet the user's power allocation requirements for the power mode, provide the user with a method for independently selecting the power mode, and the user can reasonably allocate power according to the progress of cooking and the state of the ingredients, greatly improving the cooking efficiency. And the adaptability to the cooking scene will be higher. For appropriate power allocation, the situation that a certain heating module 110 works continuously for too long at high power can be reduced, and the service life of the mandarin duck hot pot 100 can be extended. In some embodiments, the user can press the switch 150 to switch the mode through voice prompts in the scene required by the design. Specifically, the switch 150 can be set on the display panel of the mandarin duck hot pot 100 together with the menu selection key, the adjustment switch 130, etc., so as to facilitate the user to operate. The switch 150 is designed to allow the user to manually switch the power mode, making it convenient for the user to select the power distribution method according to the cooking scene and needs.

[0124] In some embodiments of the present application, the adjustment switch 130 is a knob switch, and the operation of the knob switch will be more convenient and intuitive, more convenient for users to adjust, and the adjustment rate is faster. The knob switch can easily realize continuous stepless adjustment, can more accurately realize the power control of the heating module, and the stepless adjustment is easier to adapt to the two power modes of the mandarin duck hot pot 100 with the single-line linkage mode and the synchronous adjustment mode. The durability of the knob switch is higher, compared with other adjustment switches 130, it is not easy to wear and age, and has a longer service life. The user feels more intuitive about the process of rotating the knob switch, and can pay more attention to the adjustment of power. For the process that the user needs to increase the power, the use scenario that needs to be monitored by the mandarin duck hot pot control method provided by the present application can be strengthened, and the rotary control signal of the knob switch is more stable, and when it rotates to the position of maximum power and continues to rotate in the direction of increasing power, its interval time judgment is more accurate, so that the judgment of whether the synchronous adjustment mode needs to be switched to the single-line linkage mode is more accurate. The knob-type switch is not prone to accidental touches, etc., and is not likely to affect the judgment conditions of the double-pot control method provided in this application. It can also reduce the occurrence of misoperations and is more suitable for this type of double-pot 100.

[0125] In some other embodiments of the present application, the adjustment switch 130 can also adopt a capacitive touch switch or a physical button switch. The advantage of this type of switch is that it is not easy for the user to adjust the power too much or too little, which is convenient for the user to directly adjust the power to the power size he needs, and can also achieve stepless adjustment. It can be adapted to this type of double-flavored hot pot 100, and the double-flavored hot pot control method disclosed in the present application can solve the problem of erroneous switching of the power distribution mode due to the accidental triggering of the power increase signal in the synchronous adjustment mode and the problem that the single-line linkage mode in the cooking preheating stage may cause the power of the heating module started first to be accidentally reduced.

[0126] In some embodiments of the present application, after the power mode is switched, a mode switching prompt sound is emitted to prompt the current power mode of the mandarin duck hot pot 100. The mode switching prompt sound can promptly prompt the user that the current mode has been switched, without the user having to check or confirm, which facilitates the user's cooking needs and enhances the convenience of operation. When necessary, additional visual display components such as indicator lights and indicator interfaces can be reduced to reduce production costs. In addition, the solution can also improve safety. The mode switching prompt sound can be fed back to the user in a timely manner to prevent misoperation, greatly enhancing the user's experience and interactivity with the mandarin duck hot pot 100. For novice users, the prompt sound can play a guiding role and reduce the user's learning cost.

[0127] In some implementations of the present application, the preset threshold is 1800-2600W, which can adapt to the carrying capacity of household sockets. Limiting the threshold range can prevent excessive power, ensure safety and stability in use, ensure the stable performance of each electrical component, and further ensure the service life of the shuangyang hot pot 100, and the threshold range can already meet daily use needs. For the synchronous adjustment mode, the maximum heating power of each heating module 110 can also be designed separately according to design needs. In one embodiment, such as when the preset threshold is 2200W and N=2, the preset sub-threshold can be set at 1000W. By leaving a margin to ensure safety needs during mode switching, as long as the total power value of all heating modules 110 is less than or equal to the preset threshold, there is no restriction here.

Among them, 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 powers of all heating loads of each heating module 110.

[0129] In one embodiment, the cooking cavity 210 is an upwardly open cavity, and the heating module 110 can be arranged below, to the side, or simultaneously arranged in the cooking cavity 210, for heating the cooking cavity 210 and the food in the cooking cavity 210. The heating module 110 can be a heating plate assembly or an electromagnetic wire plate assembly, etc.
