Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, in the process of heating a plurality of electric heating areas of an electromagnetic baking tray, the heating power of individual areas may fluctuate, even intermittent heating problems occur, and the cooking effect is affected. Based on this, the kitchen appliance control method, the kitchen appliance control device and the electronic equipment provided by the embodiment of the invention can be applied to equipment which can realize human-computer interaction, such as kitchen appliances, computers, mobile phones, tablet computers, servers and the like, and particularly relates to a control method for preventing mutual interference among multiple coil discs.
For the convenience of understanding the present embodiment, a detailed description will be given to a kitchen appliance control method disclosed in the present embodiment.
The first embodiment is as follows:
the embodiment provides a kitchen appliance control method, which is applied to a control module of a kitchen appliance, wherein the kitchen appliance comprises a plurality of heating modules; referring to a flowchart of a kitchen appliance control method shown in fig. 1, the kitchen appliance control method includes the steps of:
and step S102, determining the heating frequency of each heating module of the kitchen appliance.
The kitchen appliance of this embodiment may include a plurality of heating modules, each of which may perform heating. The kitchen appliance in this embodiment includes a control module, and the control module may be an MCU (micro controller Unit), and the control module may determine a heating frequency of each heating module of the kitchen appliance.
The frequency detection module for detecting the heating frequency of each heating module may be disposed in each heating module, or may be disposed outside each heating module. For example: each heating module is provided with a frequency detection module, and the heating frequency of each heating module is detected through the frequency detection module. After the frequency detection module detects the heating frequency, the detected heating frequency can be sent to a control module of the kitchen appliance.
And step S104, judging whether the difference values of the heating frequencies of the heating modules are all smaller than a preset first threshold value.
The control module can determine whether the difference values of the heating frequencies of the heating modules are all smaller than a preset first threshold, and if the difference values of the heating frequencies of the heating modules are all smaller than the first threshold, the heating frequencies of the heating modules are considered to be approximately consistent and to be in a same-frequency state, and frequency difference of the heating frequencies of the heating modules does not need to be eliminated.
Step S106, if not, adjusting the heating frequency of the heating module to be a reference frequency; wherein the reference frequency is greater than a minimum value of the heating frequencies of the heating modules, and the reference frequency is less than a maximum value of the heating frequencies of the heating modules.
If at least one of the differences between the heating frequencies of the heating modules is greater than or equal to the first threshold, the heating frequencies of the heating modules are not consistent, and the frequency difference between the heating frequencies of the heating modules needs to be eliminated. The heating frequency of the heating modules can be adjusted to be a reference frequency so as to eliminate the frequency difference of the heating frequency of each heating module. To facilitate elimination of the frequency difference, the reference may be greater than a minimum value of the heating frequency of the heating module and less than a maximum value of the heating frequency of the heating module. For example: the heating frequencies of the heating modules are respectively 200Hz, 205Hz, 208Hz and 210Hz, and the reference frequency can be (200Hz and 210 Hz).
According to the kitchen appliance control method provided by the embodiment of the invention, if the difference value of the heating frequencies of at least one heating module is greater than or equal to the first threshold value, the heating frequency of the heating module is adjusted to be the reference frequency. Through the heating frequency of adjustment heating module in this mode, can guarantee that the heating frequency of each heating module is unanimous, can eliminate the frequency difference of each heating module to prevent the emergence of the heating frequency fluctuation and the intermittent type nature heating condition, thereby improve the culinary art effect, increase user's use experience.
Example two:
the embodiment provides another kitchen appliance control method, which is realized on the basis of the embodiment; the embodiment focuses on a specific implementation manner of the pot detection operation performed by each heating module.
The kitchen appliance in the embodiment can be a kitchen range, and the heating module of the kitchen appliance can be a coil panel of the kitchen range. Referring to the schematic view of one cooktop shown in fig. 2, the cooktop in fig. 2 may be a multiple-head cooker that includes a plurality of heating modules, including a grill pan heating module and a plurality of individual heating modules. Wherein, the coil panel 1-2 is a baking tray function heating module (namely a double-wire panel) and the distance between the wire panels is smaller, and the coil panel 3-7 is a baking tray function heating module (namely a multi-wire panel) and the distance between the wire panels is smaller. The coil panels 8-10 are a plurality of individual burner zones, said multi-burner further comprising a control module 11.
Wherein, the pan is put on the baking tray area and can realize electromagnetic heating. In order to realize the baking effect of the baking tray, a plurality of small wire coils are generally used for realizing the low-power heating of a plurality of areas to maintain the temperature of the baking tray, and the independent wire coils in the baking tray area can also be independently heated to realize a low-power heating module. The distances among the coil panel 8, the coil panel 9 and the coil panel 10 are larger, so that electromagnetic interference sound is less prone to be generated in the heating process. The method provided by the embodiment can be suitable for baking trays on a multi-head stove, can also be suitable for single electromagnetic baking tray products, and can also be suitable for operation combination of all close-distance multi-tray.
Under the condition that the multiple wire coils are heated simultaneously and the distance between the wire coils is very close, electromagnetic interference sound is easy to occur when the power is started, and the phenomenon of abnormal power is easy to occur in the heating process. The kitchen appliance control method provided by the embodiment can solve the problems of noise, power intermittence and power fluctuation caused by electromagnetic interference. In addition, the distance between the coil panels is not limited to a specific value, and may be any distance that is caused by the close-distance wire coil.
In addition, referring to the schematic diagram of the connection relationship of the kitchen appliance shown in fig. 3, it can be seen that the MCU of the control module in fig. 3 is a control module, the kitchen appliance may include n heating modules in the multi-coil area shown in fig. 3, wherein the control module and each heating module in the multi-coil area may transmit and receive data in real time in an optical coupling isolation frequency communication manner; the control module can send the control power gear to the heating module 1, the heating module 2 and the like in real time; each heating module may have a separate control module (i.e., MCU1-MCUn) and frequency detection module.
Based on the above description, referring to the flowchart of another kitchen appliance control method shown in fig. 4, the kitchen appliance control method in this embodiment includes the following steps:
step S402, pot detection operation is carried out on each heating module of the kitchen appliance; and the time difference of pot detection operation of each heating module is smaller than a preset second threshold value.
Before the pot inspection operation, the user may send a heating instruction like a control module of the kitchen appliance, for example, the method further includes: and sending heating instructions to each heating module of the kitchen appliance.
Wherein, above-mentioned heating instruction can characterize multizone heating, also can characterize single zone heating, if the heating instruction singly characterizes zone heating, for example use coil panel 8, coil panel 9 or coil panel 10 in fig. 3 to heat, because the coil panel distance between the independent heating module is great, only need according to normal heating procedure can, then need not to carry out and provide more kitchen appliance control methods in this embodiment, only need to heat according to heating instruction control coil panel 8, coil panel 9 or coil panel 10.
If the heating instructions are indicative of multi-zone heating, the steps provided by the present embodiment to determine the heating frequency of each heating module of the kitchen appliance may be performed. For example, when a user operates a related function including a multi-coil heating module such as a grill pan area, and the information received by the grill pan area heating system is correct at this time, the pan detection operation needs to be simultaneously performed by each heating module in the grill pan area, and the difference in total pan detection time of each heating module needs to be smaller than a preset second threshold (the second threshold is preferably within 300 ms), and the shorter the difference is, the better the difference is. Thereby guarantee to examine pot uniformity, guarantee that the heating frequency of each heating module after the oscillation starting is unanimous, also can guarantee simultaneously to examine pot sound overlapping and not follow each other, prevent to appear noise interference.
In addition, the time difference of pot detection is not limited to the second threshold, the time difference is related to communication delay, the pot detection sounds of all heating modules are overlapped as long as the 'clicking' sounds of all heating modules of the pot detection are not followed in the user experience process, the pot detection sounds of all heating modules are only heard once in the user use process, and therefore the occurrence of interference noise is prevented.
After the pot detection of each heating module is completed, the same heating gear can be configured for each heating module.
And step S404, determining the heating frequency of each heating module of the kitchen appliance.
As shown in fig. 3, the kitchen appliance of the present embodiment includes a plurality of frequency detection modules, and the control module can receive the heating frequency of each heating module sent by the plurality of frequency detection modules by detecting the heating frequency of each heating module through the frequency detection module.
In fig. 3, the heating frequency of each heating module is detected by the frequency detection module of the heating module. The frequency detection module of each heating module can be a detection device built in the MCU or an external detection circuit. Each heating module is provided with a frequency detection module and a control module, and the control module controls the frequency detection module to detect the heating frequency of the heating module. For example, each heating module may detect its heating frequency through the frequency detection module after the oscillation power is started, and report data of the frequencies F1, F2, …, and Fn to the control module.
The control module may first determine that the respective heating frequency anomalies received are, for example: judging whether the heating frequency of each heating module meets a preset frequency range or not; if the heating frequency of each heating module accords with the frequency range, executing a step of judging whether the difference value of the heating frequency of each heating module is smaller than a preset first threshold value; if the heating frequency of at least one heating module does not accord with the frequency range, alarm information is sent; the alarm information represents that the heating module with the heating frequency not conforming to the frequency range is abnormal.
If the heating frequency of each heating module accords with the frequency range, the heating frequency is normal, the heating module corresponding to the heating frequency which does not accord with the frequency range is an abnormal heating module, and alarm information for representing the abnormal heating module can be sent to prompt a user to maintain the heating module.
Step S406, judging whether the difference values of the heating frequencies of the heating modules are all smaller than a preset first threshold value.
When detecting whether the difference value of the heating frequency of each heating module is smaller than the preset first threshold, only detecting whether the difference value of the maximum value and the minimum value of the heating module is smaller than the preset first threshold, for example: determining the maximum value and the minimum value of the heating frequency of each heating module; calculating the difference between the maximum value and the minimum value to obtain frequency difference; and judging whether the frequency difference is smaller than a preset first threshold value.
If each heating module is normal, frequencies F1, F2, … and Fn of each heating module can be arranged through a sorting algorithm, a maximum frequency Fmax and a minimum frequency Fmin are taken out, and the frequency difference delta F between the maximum value and the minimum value is calculated to be Fmax-Fmin. If the delta F is larger than a preset first threshold (preferably 1KHz), judging different frequencies and needing to be adjusted; if af is less than or equal to the first threshold, the default frequencies are consistent or close and no further adjustment is performed.
Step S408, if not, adjusting the heating frequency of the heating module as a reference frequency; wherein the reference frequency is greater than a minimum value of the heating frequencies of the heating modules, and the reference frequency is less than a maximum value of the heating frequencies of the heating modules.
First, a reference frequency needs to be calculated, and then the heating frequency of the heating module can be adjusted by a Programmable Pulse Generator (PPG), for example: determining a reference frequency; based on the reference frequency and the heating frequency of the heating module, the width of the programmable pulse wave generator of the heating module is adjusted, so that the heating frequency of the heating module is adjusted to be the reference frequency.
Among them, the heating frequency of each heating module may be used as a reference frequency, for example: the average value of the heating frequencies of the heating modules is determined, and the average value is used as a reference frequency.
The control module may quickly calculate an average value F of the heating frequency as (F1+ F2+ … + Fn)/n, taking F as a reference frequency, and the control module may transmit the reference frequency F to the heating module; after receiving the reference frequency F, each heating module compensates and adjusts the heating frequency difference by modulating the heating driving PPG, so that the frequency difference of each heating module does not exceed a certain value (preferably 1 KHz).
In the calculation of the frequency reference value, the calculation average value is not necessarily used as the reference frequency, and the calculation and frequency adjustment processing may be performed by each heater module at the reference frequency based on the frequency of any heater module having a normal frequency.
Specifically, the frequency difference of each heating module can be adjusted by: if the reference frequency is greater than the heating frequency of the heating module, reducing the width of the programmable pulse generator of the heating module; if the reference frequency is less than the heating frequency of the heating module, increasing the width of the programmable pulse generator of the heating module; if the reference frequency is equal to the heating frequency of the heating module, the width of the programmable pulse generator of the heating module is kept constant.
After receiving the reference frequency F, the MCU of each heating module calculates the difference between the corresponding frequency value and the reference frequency, Δ Fmark1 ═ F-F1, [ delta ] Fmark2 ═ F-F2, …, [ delta ] Fmarkn ═ F-Fn, and then determines whether the difference between [ delta ] Fmark1, [ delta ] Fmark2, …, [ delta ] Fmarkn is equal to zero, greater than zero, or less than zero.
Under the condition that the delta Fmark1, the delta Fmark2, … and the delta Fmark n are equal to zero, directly entering a normal heating process and exiting a frequency modulation process; when Δ Fmark1, Δ Fmark2, …, Δ Fmarkn is greater than zero, the width of the PPG should be reduced until Fmark1 ═ F1, Δ Fmark2 ═ F2, …, Δ Fmarkn ═ Fn, and the frequency modulation process is exited; when Δ Fmark1, Δ Fmark2, …, Δ Fmarkn is less than zero, the PPG width should be increased until Fmark1 ═ F1, Δ Fmark2 ═ F2, …, Δ Fmarkn ═ Fn, and the frequency modulation procedure is exited.
In addition, the limitation of PPG adjustment can be considered when the difference values of delta Fmark1, delta Fmark2, … and delta Fmark n are judged, the condition that the difference values are not consistent with the reference frequency in the adjustment process is prevented, as long as the heating module is not interfered by frequency difference, the difference values of delta Fmark1, delta Fmark2, … and delta Fmark n can be within a certain range, the difference value is not necessarily fixed to be zero, and the adjustment frequency can be close to the reference frequency as far as possible.
After the frequency modulation process is completed, the heating module may be controlled to heat, for example: and controlling the heating module to heat based on the adjusted heating frequency of the heating module.
The overall flow of the kitchen appliance control method provided by the embodiment of the invention can be shown in the overall flow schematic diagram of the kitchen appliance control method shown in fig. 5.
Determining whether the instruction of the user is an instruction corresponding to the heating function of the baking tray, if not, only checking the pan of each wire coil in the independent area, and completing the heating function; if yes, the pan detection is carried out on each wire coil in the baking tray area at the same time, the total time difference of the pan detection of each heating module needs to be smaller than a preset second threshold value, the pan detection sound is consistent, continuous 'clicking' sound cannot occur, and therefore noise interference is eliminated.
And then, all heating modules in a baking tray area of the kitchen appliance can be quickly started, the heating frequency of each heating module is detected by the frequency detection module, and the heating frequency is reported to the control module. The control module receives each heating module frequency, for example: f1, F2, F3, … and Fn.
And respectively detecting whether each frequency is abnormal or not, if the abnormal heating frequency exists, alarming, sending the heating module corresponding to the abnormal heating frequency to the control module, and displaying an alarm error.
If all the heating frequencies are normal, the control module can arrange all the frequencies in sequence, take out the maximum frequency and the minimum frequency value, and calculate the difference value delta F between the maximum frequency and the minimum frequency value which is Fmax-Fmin.
