[0052] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0053] In one embodiment, the present application provides a multi-head induction cooker heating control method. The following embodiment describes the method as applied to the control module of the multi-head induction cooker. The control module can be understood as an integrated control unit, such as a micro control unit, and the present application does not impose any specific restrictions on this.

[0054] like Figure 1 As shown, the present application provides a heating control method for a multi-burner induction cooker, the multi-burner induction cooker comprising a control module and a plurality of heating units. The method is applied to the control module and comprises:

[0055] Step S101: receiving a heating start instruction initiated by a user, and judging whether multiple heating units are required to start heating according to the heating start instruction.

[0056] Among them, the heating unit is generally an excitation coil, which is wound by multiple strands of copper wire.

[0057] It is understandable that when the user needs to use a multi-head induction cooker for heating, he will set various parameters according to his own needs, such as: expected power, heating time, etc. After the user completes the setting of various parameters, a start heating instruction is generated based on the various parameters set by the user and the range of the heating unit covered by the bottom of the pot, triggering the multi-head induction cooker to start heating. The control module in the multi-head induction cooker receives the start heating instruction, and then controls the corresponding heating unit to start heating.

[0058] Specifically, when only one heating unit starts heating, the multi-head induction cooker will only generate one heating frequency and cannot form multiple heating frequencies to act on the same pot. Therefore, when only one heating unit starts heating, no noise can be generated. That is, when only one heating unit starts heating, there is no need to activate the multi-head induction cooker heating control method.

[0059] Step S102: If multiple heating units are required to start heating, the target power corresponding to each heating unit to start heating is determined according to the heating start instruction.

[0060] Among them, the target power is one of the parameters set by the user. Each heating unit that starts heating has its corresponding target power. For any one of the heating units that starts heating, the target power is the expected power set by the user. If the user does not set the expected power for the heating unit, the default power corresponding to the heating unit can be set to the expected power.

[0061] Step S103: determining whether the target power and hardware parameters of each heating unit that starts heating meet preset conditions.

[0062] The hardware parameters of the heating unit include but are not limited to the frequency range that can be heated, the power range that can be operated, and the coil disk specifications.

[0063] Step S104: If the target power and hardware parameters of each heating unit that starts heating meet the preset conditions, then according to the preset mapping relationship between the working power and heating frequency of each heating unit, the heating unit corresponding to the smallest heating frequency among the heating frequencies corresponding to the target power of each heating unit that starts heating is determined as the first heating unit.

[0064] It can be understood that the mapping relationship between the working power and the heating frequency of each heating unit is, for one of the heating units, a one-to-one correspondence between the working power and the heating frequency of the heating unit.

[0065] For example, assuming that the heating units that start heating include heating unit A and heating unit B, and their target powers are 1000W and 500W respectively, then according to the mapping relationship between the working power and heating frequency of each heating unit, it can be obtained that the heating frequency corresponding to heating unit A when its target power is 1000W is 30kHz, and the heating frequency corresponding to heating unit B when its target power is 500W is 40kHz. At this time, the minimum heating frequency corresponding to the target power of the heating unit that starts heating is 30kHz, and heating unit A is determined as the first heating unit.

[0066] Step S105: Calculate the heating duty cycle corresponding to each second heating unit respectively.

[0067] Among them, the second heating unit is any heating unit among the heating units that start heating except the first heating unit, and the heating duty cycle is the ratio of the heating time of the corresponding second heating unit in a heating cycle to the total time of a heating cycle.

[0068] Step S106: determining the target frequency corresponding to each second heating unit according to the target heating frequency.

[0069] The target heating frequency is a heating frequency corresponding to the target power of the first heating unit; and the difference between the target frequency corresponding to each second heating unit and the target heating frequency is within a preset range.

[0070] It is understandable that the preset range can be set by R&D personnel based on relevant parameters of the multi-burner induction cooker, and the left endpoint of the preset range can be 0, that is, the target frequency corresponding to the second heating unit can be equal to the target heating frequency.

[0071] Step S107: controlling the first heating unit to continuously heat at the target heating frequency.

[0072] Step S108: According to the preset heating cycle period, the heating duty cycle and target frequency corresponding to each second heating unit, control each second heating unit to perform intermittent heating at its corresponding target frequency to ensure that the average power of each second heating unit in each heating cycle period is equal to its corresponding target power.

[0073] It can be understood that since the relationship between the heating frequency and the working power of the same heating unit is negatively correlated, when the second heating unit heats at its respective target frequency, its working power is higher than its target power. In order to make the average power reach the target power set by the user, it is necessary to calculate the corresponding heating duty cycle and perform intermittent heating according to the heating duty cycle to ensure that the average power of each second heating unit in each heating cycle is equal to its respective target power.

[0074] Step S109: If the target power and hardware parameters of each heating unit that has started heating do not meet the preset conditions, each heating unit that has started heating is controlled to continue heating at its corresponding target power.

[0075] Specifically, the target power and hardware parameters of each heating unit that starts heating do not meet the preset conditions, that is, the target power of each heating unit that starts heating is the same, and the hardware parameters of each heating unit that starts heating are the same. At this time, since the hardware parameters and target power are the same, the heating frequencies corresponding to each heating unit that starts heating are the same. In other words, in this case, the multi-head induction cooker does not generate noise.

[0076] The multi-head induction cooker heating control method provided by the present application receives a start-up heating instruction initiated by a user, and determines whether multiple heating units are required to start heating according to the start-up heating instruction. If multiple heating units are required to start heating, the target power corresponding to each heating unit that starts heating is determined according to the start-up heating instruction. If the target power and hardware parameters of each heating unit that starts heating meet the preset conditions, the heating unit corresponding to the smallest heating frequency among the heating frequencies corresponding to the target powers of each heating unit that starts heating is determined as the first heating unit according to the preset mapping relationship between the working power and the heating frequency of each heating unit, and then the heating unit corresponding to the smallest heating frequency among the heating frequencies corresponding to the target powers of each heating unit that starts heating is calculated respectively. The corresponding heating duty cycle is determined according to the target heating frequency, and the target frequency corresponding to each second heating unit is determined. Finally, the first heating unit is controlled to heat continuously at the target heating frequency, and according to the preset heating cycle period, the heating duty cycle corresponding to each second heating unit and the target frequency, each second heating unit is controlled to perform intermittent heating at its corresponding target frequency, so as to ensure that the average power of each second heating unit in each heating cycle period is equal to its corresponding target power, wherein the second heating unit is any heating unit other than the first heating unit among the heating units that have started heating, and the target heating frequency is the heating frequency corresponding to the target power of the first heating unit. When the first heating unit is operating at the target heating frequency, each second heating unit is intermittently heated with its corresponding heating duty cycle, so that when each second heating unit is operating at its corresponding target frequency, the average power can reach its respective target power, thereby achieving the same or similar heating frequency for all heating units that have started heating during heating, eliminating or significantly reducing noise from the root, and improving the cooking experience.

[0077] In one embodiment, the preset condition is:

[0078] The hardware parameters of the heating units started for heating are the same, and the target powers corresponding to the heating units started for heating are different;

[0079] or,

[0080] The hardware parameters of the heating units that start heating are different, and the target powers corresponding to the heating units that start heating are the same;

[0081] or,

[0082] The hardware parameters of the heating units that are started for heating are different, and the target powers corresponding to the heating units that are started for heating are different.

[0083] like Figure 2As shown, in one embodiment, the process of constructing the mapping relationship between the operating power and heating frequency of each heating unit includes:

[0084] Step S201: determining a heating frequency range according to hardware parameters of each heating unit in the multi-burner induction cooker.

[0085] The heating frequency range is a range within which each heating unit can heat normally.

[0086] For example, assuming that the multi-head induction cooker has a heating unit A and a heating unit B, when the hardware parameters of the heating unit A and the heating unit B are the same, the heating frequency ranges of the heating unit A and the heating unit B can be assumed to be 20kHz-50kHz, and the heating frequency range is 20kHz-50kHz. When the hardware parameters of the heating unit A and the heating unit B are different, the heating frequency ranges of the heating unit A and the heating unit B can be assumed to be 20kHz-50kHz and 30kHz-60kHz respectively, and the heating frequency range is 30kHz-50kHz.

[0087] Furthermore, even if the hardware parameters of the various heating units are different, when designing the various heating units of the multi-burner induction cooker, it is ensured that there is a heating frequency range within which the various heating units can operate normally.

[0088] Step S202: testing each heating unit to obtain the operating power of each heating unit corresponding to the heating frequency within the heating frequency range.

[0089] Step S203: establishing a mapping relationship between the operating power within the heating frequency range of each heating unit and the heating frequency in a one-to-one correspondence.

[0090] It can be understood that by testing each heating unit, the mapping relationship between the working power and heating frequency of each heating unit is obtained, so that the heating duty cycle of the second heating unit can be calculated during the heating control of the multi-head induction cooker, so that when each second heating unit works at its corresponding target frequency, the average power can reach its respective target power. Under this premise, the heating frequencies of all heating units that have started heating are the same or similar during heating, thereby greatly reducing or eliminating noise from the source.

[0091] like Figure 3 As shown, in one embodiment, respectively calculating the heating duty cycle corresponding to each second heating unit includes:

[0092] Step S301: according to the preset mapping relationship between the working power and the heating frequency of each heating unit, the working power of each second heating unit when heating at the corresponding target frequency is obtained.

[0093] Step S302: taking the ratio of the target power corresponding to each second heating unit to the working power of the second heating unit when heating at the corresponding target frequency as the heating duty cycle corresponding to the second heating unit.

[0094] It can be understood that the calculation of the heating duty cycle of the second heating unit and the intermittent heating of the second heating unit with its corresponding heating duty cycle is to ensure that when the second heating unit is heated at its respective target frequencies, the average power of the second heating unit can still be equal to its corresponding target power in a heating cycle, so as to achieve the expected power set by the user, so as to ensure that while reducing or even eliminating noise, it does not affect the user's cooking needs and improves the user's cooking experience.

[0095] For example, when the target power and hardware parameters of each heating unit that starts heating meet the preset conditions, there are the following three situations:

[0096] Example 1: When the hardware parameters of the heating units that have started heating are the same, and the target powers corresponding to the heating units that have started heating are different:

[0097] Assume that the heating units that start heating are heating unit A and heating unit B, and the hardware parameters of heating unit A and heating unit B are the same. The target power of heating unit A is 1000W, and the target power of heating unit B is 500W. At this time, according to the mapping relationship between the working power and heating frequency corresponding to heating unit A and heating unit B, it can be obtained that when the target power of heating unit A is 1000W, the heating frequency is 30kHz, and when the target power of heating unit B is 500W, the heating frequency is 40kHz. In this case, heating unit A is determined as the first heating unit. Determine heating unit B as the second heating unit, and the target heating frequency is 30kHz. Assuming that the target frequency of heating unit B is 30kHz, when heating unit B operates at a heating frequency of 30kHz, due to the same hardware parameters, the operating power of heating unit B is 1000W, then the heating duty cycle of heating unit B is calculated to be 50% (500W / 1000W), and heating unit A is controlled to continuously heat at a heating frequency of 30kHz, and heating unit B is controlled to intermittently heat at a heating duty cycle of 50% and a heating frequency of 30kHz within a preset heating cycle.

[0098] like Figure 4 As shown, Figure 4The relationship between the driving opening and closing and time corresponding to the above example 1, T is a preset heating cycle, the IGBT drive is the module that drives the heating unit to start heating, the open drive starts heating, and the closed drive stops heating. Figure 4 , the heating duty cycle of heating unit B can be calculated to be 50% (2.5T / 5T), which is consistent with the heating duty cycle calculated for heating unit B in Example 1, thereby controlling heating unit A to heat continuously and controlling heating unit B to heat intermittently with a heating duty cycle of 50% within a preset heating cycle.

[0099] Example 2: When the hardware parameters of the heating units that have started heating are different, and the target powers corresponding to the heating units that have started heating are the same:

[0100] Assume that the heating units that start heating are heating unit C and heating unit D, and the hardware parameters of heating unit C and heating unit D are different. The target power of heating unit C and heating unit D are both 1000W. At this time, according to the mapping relationship between the working power and heating frequency corresponding to each of heating unit C and heating unit D, due to the different hardware parameters, it can be assumed that when the target power of heating unit C is 1000W, the heating frequency is 30kHz, and when the target power of heating unit D is 1000W, the heating frequency is 40kHz. Then heating unit C is determined as the first heating unit and heating unit D is determined as the second heating unit. The target heating frequency is 1000W. The thermal frequency is 30kHz. Assuming that the target frequency of heating unit D is 29.8kHz, when heating unit D operates at a heating frequency of 29.8kHz, since the hardware parameters are different and the relationship between the working power and heating frequency of the same heating unit is negatively correlated, the working power of heating unit D can be assumed to be 1200W, and the heating duty cycle of heating unit D is calculated to be 83.3% (1000W / 1200W). The heating unit C is controlled to continuously heat at a heating frequency of 30kHz, and the heating unit D is controlled to intermittently heat at a heating duty cycle of 83.3% and a heating frequency of 29.8kHz within a preset heating cycle.

[0101] Example 3: When the hardware parameters of the heating units that have started heating are different, and the target powers corresponding to the heating units that have started heating are different:

[0102] Assume that the heating units started for heating are heating unit E and heating unit F, and the hardware parameters of heating unit E and heating unit F are different. The target power of heating unit E is 800W, and the target power of heating unit F is 500W. According to the mapping relationship between the working power and heating frequency corresponding to heating unit E and heating unit F, since the hardware parameters are different, it can be assumed that when the target power of heating unit E is 800W, the heating frequency is 40kHz, and when the target power of heating unit F is 500W, the heating frequency is 30kHz. Then, heating unit F is determined as the first heating unit, and heating unit E is determined as the second heating unit. The target heating frequency is 30kHz. Assuming that the target frequency of heating unit E is 29.8kHz, when heating unit E operates at a heating frequency of 29.8kHz, since the hardware parameters are different and the relationship between the working power and heating frequency of the same heating unit is negatively correlated, the working power of heating unit E can be assumed to be 1000W, and the heating duty cycle of the second heating unit is calculated to be 80% (800W / 1000W). The heating unit F is controlled to continuously heat at a heating frequency of 30kHz, and the heating unit E is controlled to intermittently heat at a heating duty cycle of 80% and a heating frequency of 29.8kHz within a preset heating cycle.

[0103] In one embodiment, controlling each second heating unit to perform intermittent heating at its corresponding target frequency according to a preset heating cycle, a heating duty cycle corresponding to each second heating unit, and a target frequency includes:

[0104] During a heating cycle, each second heating unit is controlled to perform intermittent heating at its corresponding target frequency according to the heating duty cycle corresponding to each second heating unit, so as to ensure that the average power of each second heating unit during the heating cycle is equal to its corresponding target power. When the heating cycle ends, the next heating cycle is entered.
