Description

Technical Field

[0001] The present invention relates to the technical field of cooking appliances, and more particularly, to a control method for a cooking appliance, a cooking appliance, and a readable storage medium. Background Art

[0002] In the related art, for a fully automatic wall breaker with an automatic water inlet function, it can automatically fill water according to the water volume set by the user and complete cooking, greatly improving the user experience.

[0003] However, the water inlet of the wall breaker is related to the water pressure of the connected water supply pipe. For users in different regions and different usage scenarios, the water supply pressure may vary greatly, resulting in water inlet errors, inconvenient use for users, and even the risk of overflow due to excessive water inlet.

[0004] Therefore, how to adapt to different water pressures and achieve quantitative water inlet is a technical problem that needs to be solved urgently at present. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0006] To this end, a first aspect of the present invention provides a control method for a cooking appliance, including:

[0007] A second aspect of the present invention provides a cooking appliance.

[0008] A third aspect of the present invention provides a readable storage medium.

[0009] In view of this, a first aspect of the present invention provides a control method for a cooking appliance, including:

[0010] Controlling the cooking appliance to fill water, determining a correction coefficient according to the water inlet volume of the cooking appliance and the weight value corresponding to the water inlet volume; controlling the cooking appliance to work according to the correction coefficient.

[0011] In this technical solution, before the cooking appliance starts cooking, first control the cooking appliance to fill water, and the water filling can be carried out according to the water inlet volume corresponding to the preset water inlet program. At the same time, control the cooking appliance to weigh to obtain the weight value corresponding to the water inlet volume, and determine the correction coefficient according to the water inlet volume and the corresponding weight value.

[0012] Among them, for example, under ideal conditions, the cooking device intakes water according to a set program. Assuming the water intake is 100 ml, the obtained weight of the water intake should also correspond to 100 g. Therefore, the default water intake can be set to 100 ml, and the corresponding weight value can be set to 100 g. After controlling the cooking device to intake 100 ml of water, if the obtained weight value is 110 g, it indicates that the water intake is inaccurate due to water pressure, and the actual water intake is approximately 110 ml. Therefore, according to this water intake and weight value, the corresponding correction coefficient can be determined.

[0013] In an embodiment of the present invention, before automatic cooking, the cooking device is controlled to intake water, and a correction coefficient is determined according to the water intake and the corresponding weight value. The cooking device is controlled to automatically intake water during automatic cooking according to the correction coefficient, which can avoid water intake errors caused by external factors such as different water pressures, ensure that the water intake matches the user's setting. On the one hand, it can improve the accuracy and reliability of the cooking device during automatic cooking, thereby improving the user experience. On the other hand, it can also prevent excessive water intake caused by water intake errors and prevent liquid overflow during cooking, thereby ensuring the safe use of the cooking device.

[0014] In addition, the control method of the cooking device in the above technical solution provided by the present invention may further have the following additional technical features:

[0015] In the above technical solution, controlling the cooking device to intake water and determining a correction coefficient according to the water intake of the cooking device and the weight value corresponding to the water intake specifically includes:

[0016] Controlling the cooking device to intake water according to the first water intake and the second water intake respectively, and weighing the first weight value corresponding to the first water intake and the second weight value corresponding to the second water intake respectively; determining a first correction coefficient according to the first water intake and the first weight value, and determining a second correction coefficient according to the second water intake and the second weight value; determining a target correction coefficient according to the first correction coefficient and the second correction coefficient.

[0017] In this technical solution, controlling the cooking device to intake water according to the first water intake and the second water intake respectively, weighing the actual water intake after intake according to the first water intake and the actual water intake after intake according to the second water intake respectively, determining the first correction coefficient and the second correction coefficient respectively, and determining the final target correction coefficient according to the two correction coefficients. By intaking water and weighing multiple times, calculating respectively according to the data of each time to determine multiple correction coefficients, and finally further determining the final target correction coefficient according to multiple correction coefficients, errors can be effectively avoided, so that the finally obtained target correction coefficient better conforms to the actual water intake situation of the cooking device, further improving the water intake accuracy, improving the accuracy and reliability of the cooking device during automatic cooking, and thus improving the user experience.

[0018] Among them, it is possible to first fill water according to the first water inflow rate, weigh the first water filling, then empty the water in the cooking device at this time, and then refill water according to the second water inflow rate again and reweigh the second water filling.

[0019] In some other embodiments, it is possible to first fill water according to the first water inflow rate, weigh the first water filling, then directly refill water according to the second water inflow rate, weigh the total water inflow of the two water fillings, and use the total weight of the first water filling and the second water filling as the second weight value.

[0020] In any of the above technical solutions, the second water inflow rate is the same as the first water inflow rate; or the second water inflow rate is N times the first water inflow rate, where N is a natural number greater than 1.

[0021] In this technical solution, the second water inflow rate can be the same as the first water inflow rate. That is to say, water is filled multiple times according to the same water inflow rate, weighed multiple times, and the calculation of the correction coefficient is performed multiple times, so as to reduce the error caused by different single water filling situations and make the finally obtained target correction coefficient more accurate.

[0022] It can be understood that for the case where the first water inflow rate and the second water inflow rate are the same, it is also possible to fill water for the third, fourth, and even the Xth time according to this water inflow rate and weigh them respectively. The more times of water filling and weighing, the smaller the influence of the error caused by single sampling on the target correction coefficient determined based on this sampling.

[0023] In some other embodiments, the second water inflow rate is different from the first water inflow rate. Specifically, the second water inflow rate can be N times the first water inflow rate, where N is a natural number greater than 1. That is to say, the second water inflow rate is a positive integer multiple of the first water inflow rate. By setting the second water inflow rate to be different from the first water inflow rate, it is possible to correct the water filling error caused by external factors under different water inflow rates, making the finally obtained target correction coefficient more accurate.

[0024] It can be understood that the first water inflow rate should be greater than the minimum measurement scale of the cooking device. For example, if the minimum water inflow rate of the cooking device is 1 ml and the minimum weighing accuracy is 1 g, then the first water inflow rate should be greater than 1 ml, such as set to 10 ml, etc. At the same time, the first water inflow rate and the second water inflow rate should be less than the maximum capacity of the cooking device.

[0025] In any of the above technical solutions, determining the first correction coefficient according to the first water inflow rate and the first weight value specifically includes:

[0026] Determine the first correction coefficient through the following formula:

[0027]

[0028] Wherein, P1 is the first correction coefficient, M1 is the first water inflow, and N1 is the first weight value.

[0029] In this technical solution, the first correction coefficient can be obtained through the above formula. Specifically, first calculate the absolute value of the difference between the first water inflow and the first weight value, and further calculate the ratio of the absolute value of the difference between the first water inflow and the first weight value to the first water inflow. The obtained ratio is the first correction coefficient.

[0030] Specifically, assume that the first water inflow is 100 ml. Since under ideal conditions, the weight of 100 ml of water is 100 g, therefore, if the actual water inflow is consistent with the first water inflow when the water is inlet according to the first water inflow, then the first water inflow, that is, M1 is 100, and the first weight value, that is, N1 should also be 100. At this time, the first correction coefficient obtained by the above formula is 1, that is, there is no need to correct the water inlet.

[0031] If the actual water inflow is different from the first water inflow and N1 is not equal to 100, then P1 is not 1, and the water inlet needs to be corrected.

[0032] In any of the above technical solutions, when the second water inflow is N times the first water inflow, before controlling the cooking device to inlet water according to the second water inflow, the control method further includes:

[0033] Controlling the cooking device to drain water and clearing the weighed weight value to zero;

[0034] Determining the second correction coefficient according to the second water inflow and the second weight value, specifically including:

[0035] Determine the second correction coefficient through the following formula:

[0036]

[0037] Wherein, P2 is the second correction coefficient, M2 is the second water inflow, and N2 is the second weight value.

[0038] In this technical solution, before the step of controlling the cooking device to inlet water according to the second water inflow, control the cooking device to drain the water therein, that is, drain the first inlet water, and at the same time clear the weighed weight value to zero. That is to say, after the first water inlet according to the first water inflow and weighing the first water inlet, empty the water in the cooking device at this time, then inlet water again according to the second water inflow, and weigh the second water inlet again.

[0039] At this time, the second correction coefficient is calculated through the above formula. Specifically, first calculate the absolute value of the difference between the second water inflow and the second weight value, and further calculate the ratio of the absolute value of the difference between the second water inflow and the second weight value to the second water inflow, and calculate the difference between 1 and the obtained ratio, which is the second correction coefficient.

[0040] Specifically, assume that the second water inflow is 200 ml. Since in the ideal case, the weight of 200 ml of water is 200 g, therefore, if the actual water inflow is consistent with the second water inflow when the water is inlet according to the second water inflow, then the second water inflow, that is, M2 is 200, and the second weight value, that is, N2 should also be 200. At this time, the second correction coefficient obtained by the above formula is 1, that is, no correction of the water inlet is required.

[0041] If the actual water inflow is different from the second water inflow and N2 is not equal to 200, then P2 is not 1, and the water inlet needs to be corrected.

[0042] By comparing the correction coefficients multiple times through the relative error correction method, errors can be effectively avoided, making the finally obtained target correction coefficient more accurate.

[0043] In any of the above technical solutions, when the second water inflow is N times the first water inflow, determining the second correction coefficient according to the second water inflow and the second weight value specifically includes:

[0044] Determine the second correction coefficient through the following formula:

[0045]

[0046] Wherein, P2 is the second correction coefficient, M1 is the first water inflow, M2 is the second water inflow, and N2 is the second weight value.

[0047] In this technical solution, since before the second water inlet, the water of the first water inlet, that is, the first water inflow, is not discharged. That is to say, after the first water inlet is carried out according to the first water inflow and the first water inlet is weighed, the second water inlet is directly carried out according to the second water inflow, and the total water inflow of the two water inlets is weighed, and the total weight of the first water inlet and the second water inlet is used as the second weight value.

[0048] Specifically, assume that the first water inflow is 100 ml and the second water inflow is 200 ml. Then after the two water inlets, the total water volume in the cooking device is 300 ml, that is, M2 + M1 is equal to 300. In the ideal case, the measured weight value of 300 ml is 300 g, that is, N2 is equal to 300. At this time, the second correction coefficient obtained by the above formula is 1, that is, no correction of the water inlet is required.

[0049] If the actual water inflow is different from the second water inflow, then N2 is not equal to 300, P2 is not 1, and the water inflow needs to be corrected.

[0050] By comparing the correction coefficients multiple times through linear error correction, errors can be effectively avoided, making the finally obtained target correction coefficient more accurate.

[0051] In any of the above technical solutions, determining the target correction coefficient according to the first correction coefficient and the second correction coefficient specifically includes:

[0052] When the absolute value of the difference between the first correction coefficient and the second correction coefficient is less than the preset threshold, the average of the first correction coefficient and the second correction coefficient is determined as the target correction coefficient.

[0053] In this technical solution, after obtaining the first correction coefficient and the second correction coefficient, further calculate the absolute value of the difference between the first correction coefficient and the second correction coefficient, and determine whether the absolute value is greater than or equal to the preset threshold. If the absolute value is less than the preset threshold, it is considered that the error between the first correction coefficient and the second correction coefficient is small, and the accuracy rates of the first correction coefficient and the second correction coefficient are high. At this time, calculate the average value of the first correction coefficient and the second correction coefficient, and use this average value as the target correction coefficient.

[0054] If the absolute value of the difference between the first correction coefficient and the second correction coefficient is greater than or equal to the preset threshold, it indicates that a large error has occurred between the first correction coefficient and the second correction coefficient. At this time, discard the obtained first correction coefficient and the second correction coefficient, and re-control the water inflow of the cooking device and re-perform calibration.

[0055] By calculating the average value of multiple correction coefficients as the final target correction coefficient after determining that there is no large error between the multiple measured correction coefficients, it is beneficial to improve the accuracy of the target correction coefficient and ultimately improve the water inflow accuracy of the cooking device.

[0056] It can be understood that the preset threshold can be set according to the actual situation, such as set to 0.2, 0.25 or 0.15, etc. The embodiments of the present application do not limit this.

[0057] In any of the above technical solutions, before controlling the water inflow of the cooking device, the control method further includes:

[0058] Control the cooking device to execute a preset self-check program, and control the cooking device to clear the weighed weight value.

[0059] In this technical solution, before controlling the cooking device to intake water, that is, before starting to calibrate the correction coefficient, the cooking device is first controlled to execute a preset self-check procedure, that is, power-on self-check. Through the self-check procedure, it is judged whether components such as the sensors, water pumps, and valves of the cooking device are normal. If normal, the calibration step can be executed. If abnormal, it may affect the calibration accuracy. At this time, corresponding prompts can be issued to inform the user that the self-check is abnormal.

[0060] Meanwhile, before water intake, the cooking device is controlled to drain water and the weighed weight value is cleared to prevent the residual water in the cooking device or the previously saved weight value from affecting the calibration accuracy.

[0061] The second aspect of the present invention provides a cooking device, including: a memory on which programs or instructions are stored; a processor for implementing the steps of the control method of the cooking device provided in any of the above technical solutions when executing the programs or instructions. Therefore, this cooking device also includes all the beneficial effects of the control method of the cooking device provided in any of the above technical solutions, which will not be elaborated here.

[0062] The third aspect of the present invention provides a readable storage medium on which programs or instructions are stored. When the programs or instructions are executed by a processor, the steps of the control method of the cooking device provided in any of the above technical solutions are implemented. Therefore, this readable storage medium also includes all the beneficial effects of the control method of the cooking device provided in any of the above technical solutions, which will not be elaborated here.

[0070] In order to more clearly understand the above objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0071] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0072] Next, refer to Figures 1 to 6 Describe a control method, a cooking device, and a readable storage medium of a cooking device according to some embodiments of the present invention.

[0073] Embodiment 1

[0074] In some embodiments of the present invention, Figure 1 One of the flowcharts of the control method of the cooking device according to the embodiment of the present invention is shown. As Figure 1 shown, the control method of the cooking device includes:

[0075] Step 102, control the cooking device to intake water, and determine a correction coefficient according to the water intake of the cooking device and the weight value corresponding to the water intake;

[0076] Step 104, control the cooking device to work according to the correction coefficient.

[0077] In the embodiment of the present invention, before the cooking device starts cooking work, first control the cooking device to intake water, and the water intake can be carried out according to the water intake corresponding to the preset water intake program. At the same time, control the cooking device to weigh to obtain the weight value corresponding to the water intake, and determine the correction coefficient according to the water intake and the corresponding weight value.

[0078] Among them, for example, under ideal conditions, the cooking device intakes water according to the set program. Assuming that the water intake is 100 ml, then the obtained water intake weight should also correspond to 100 g. Therefore, the default water intake can be set to 100 ml, and the corresponding weight value can be set to 100 g. After controlling the cooking device to intake 100 ml of water, if the obtained weight value is 110 g, it means that the water intake is inaccurate due to water pressure, and the actual water intake is about 110 ml. Therefore, according to the water intake and the weight value, the corresponding correction coefficient can be determined.

[0079] In an embodiment of the present invention, before automatic cooking, the cooking device is controlled to intake water. The correction coefficient is determined according to the water intake amount and the corresponding weight value. During the automatic cooking process, the cooking device is controlled to intake water automatically according to the correction coefficient, which can avoid the water intake error caused by external factors such as different water pressures, ensure that the water intake amount matches the user's setting. On the one hand, it can improve the accuracy and reliability of the cooking device during automatic cooking, thereby improving the user experience. On the other hand, it can also prevent excessive water intake caused by the water intake error and prevent liquid overflow during the cooking process, thus ensuring the safe use of the cooking device.

[0080] Embodiment 2

[0081] In some embodiments of the present invention, Figure 2 Fig. 2 shows the second flowchart of the control method of the cooking device according to the embodiment of the present invention. As Figure 2 shown, the cooking device is controlled to intake water, and the correction coefficient is determined according to the water intake amount of the cooking device and the weight value corresponding to the water intake amount, specifically including:

[0082] Step 202, control the cooking device to intake water according to the first water intake amount and the second water intake amount respectively, and weigh the first weight value corresponding to the first water intake amount and the second weight value corresponding to the second water intake amount respectively;

[0083] Step 204, determine the first correction coefficient according to the first water intake amount and the first weight value, and determine the second correction coefficient according to the second water intake amount and the second weight value;

[0084] Step 206, determine the target correction coefficient according to the first correction coefficient and the second correction coefficient.

[0085] In the embodiment of the present invention, the cooking device is controlled to intake water according to the first water intake amount and the second water intake amount respectively. At the same time, the actual water intake amount after intake water according to the first water intake amount is weighed respectively, and the actual water intake amount after intake water according to the second water intake amount is weighed respectively. The first correction coefficient and the second correction coefficient are determined respectively, and the final target correction coefficient is determined according to the two correction coefficients. By intaking water and weighing multiple times, and calculating respectively according to the data of each time to determine multiple correction coefficients, and finally further determining the final target correction coefficient according to multiple correction coefficients, the error can be effectively avoided, so that the finally obtained target correction coefficient better conforms to the actual water intake situation of the cooking device, thereby further improving the water intake accuracy, improving the accuracy and reliability of the cooking device during automatic cooking, and thus improving the user experience.

[0086] Among them, after the first water intake is carried out according to the first water intake amount and the first water intake is weighed, the water in the cooking device can be emptied at this time, and then the second water intake is carried out again according to the second water intake amount, and the second water intake is weighed again.

[0087] In some other embodiments, after the first water inlet is performed according to the first water inlet volume and the first water inlet is weighed, the second water inlet can be directly performed according to the second water inlet volume, the total water inlet volume of the two water inlets is weighed, and the total weight of the first water inlet and the second water inlet is used as the second weight value.

[0088] Example III

[0089] In some embodiments of the present invention, the second water inlet volume is the same as the first water inlet volume; or the second water inlet volume is N times the first water inlet volume, where N is a natural number greater than 1.

[0090] In an embodiment of the present invention, the second water inlet volume can be the same as the first water inlet volume. That is to say, water inlet is performed multiple times according to the same water inlet volume, weighed multiple times, and the calculation of the correction coefficient is performed multiple times, so as to reduce the error caused by different single water inlet conditions, and make the finally obtained target correction coefficient more accurate.

[0091] It can be understood that for the case where the first water inlet volume and the second water inlet volume are the same, the third, fourth, and even the Xth water inlet can be performed according to this water inlet volume and weighed respectively. The more times of water inlet and weighing, the smaller the influence of the error caused by single sampling on the target correction coefficient determined according to this sampling.

[0092] In some other embodiments, the second water inlet volume is different from the first water inlet volume. Specifically, the second water inlet volume can be N times the first water inlet volume, where N is a natural number greater than 1. That is to say, the second water inlet volume is a positive integer multiple of the first water inlet volume. By setting the second water inlet volume to be different from the first water inlet volume, the water inlet error caused by external factors under different water inlet volumes can be corrected, and the finally obtained target correction coefficient is more accurate.

[0093] It can be understood that the first water inlet volume should be greater than the minimum measurement scale of the cooking device. For example, if the minimum water inlet volume of the cooking device is 1 ml and the minimum weighing accuracy is 1 g, the first water inlet volume should be greater than 1 ml, such as set to 10 ml, etc. At the same time, the first water inlet volume and the second water inlet volume should be less than the maximum capacity of the cooking device.

[0094] Example IV

[0095] In some embodiments of the present invention, determining the first correction coefficient according to the first water inlet volume and the first weight value specifically includes:

[0096] The first correction coefficient is determined by the following formula:

[0097]

[0098] Wherein, P1 is the first correction coefficient, M1 is the first water inflow, and N1 is the first weight value.

[0099] In this embodiment, the first correction coefficient can be obtained through the above formula. Specifically, first calculate the absolute value of the difference between the first water inflow and the first weight value, and further calculate the ratio of the absolute value of the difference between the first water inflow and the first weight value to the first water inflow. The obtained ratio is the first correction coefficient.

[0100] Specifically, assume that the first water inflow is 100 ml. Since in the ideal case, the weight of 100 ml of water is 100 g, therefore, if the actual water inflow is consistent with the first water inflow when the water is filled according to the first water inflow, then the first water inflow, that is, M1 is 100, and the first weight value, that is, N1 should also be 100. At this time, the first correction coefficient obtained by the above formula is 1, that is, there is no need to correct the water inflow.

[0101] If the actual water inflow is different from the first water inflow and N1 is not equal to 100, then P1 is not 1 and the water inflow needs to be corrected.

[0102] Embodiment Five

[0103] In some embodiments of the present invention, when the second water inflow is N times the first water inflow, before controlling the cooking device to fill water according to the second water inflow, the control method further includes:

[0104] Controlling the cooking device to drain water and clearing the weighed weight value to zero;

[0105] Determining the second correction coefficient according to the second water inflow and the second weight value, specifically including:

[0106] Determining the second correction coefficient through the following formula:

[0107]

[0108] Wherein, P2 is the second correction coefficient, M2 is the second water inflow, and N2 is the second weight value.

[0109] In the embodiment of the present invention, before the step of controlling the cooking device to fill water according to the second water inflow, control the cooking device to drain the water therein, that is, drain the first water inflow, and at the same time clear the weighed weight value to zero. That is to say, after the first water inflow is filled according to the first water inflow and the first water inflow is weighed, empty the water in the cooking device at this time, and then refill water according to the second water inflow again and weigh the second water inflow again.

[0110] At this time, the second correction coefficient is calculated through the above formula. Specifically, first, calculate the absolute value of the difference between the second water inflow and the second weight value, and further calculate the ratio of the absolute value of the difference between the second water inflow and the second weight value to the second water inflow. Calculate the difference between 1 and the obtained ratio, which is the second correction coefficient.

[0111] Specifically, assume that the second water inflow is 200 ml. Since in the ideal case, the weight of 200 ml of water is 200 g, therefore, if the actual water inflow conforms to the second water inflow when filling water according to the second water inflow, then the second water inflow, that is, M2 is 200, and the second weight value, that is, N2 should also be 200. At this time, the second correction coefficient obtained by the above formula is 1, that is, no correction of the water inflow is required.

[0112] If the actual water inflow is different from the second water inflow and N2 is not equal to 200, then P2 is not 1, and the water inflow needs to be corrected.

[0113] By comparing the correction coefficients multiple times through the relative error correction method, errors can be effectively avoided, making the finally obtained target correction coefficient more accurate.

[0114] Embodiment Six

[0115] In some embodiments of the present invention, when the second water inflow is N times the first water inflow, the second correction coefficient is determined according to the second water inflow and the second weight value, which specifically includes:

[0116] The second correction coefficient is determined through the following formula:

[0117]

[0118] Wherein, P2 is the second correction coefficient, M1 is the first water inflow, M2 is the second water inflow, and N2 is the second weight value.

[0119] In the embodiments of the present invention, since the water of the first water inflow is not discharged before the second water filling, that is to say, after filling water according to the first water inflow for the first time and weighing the first water filling, directly fill water again according to the second water inflow, and weigh the total water inflow of the two water fillings, and use the total weight of the first water filling and the second water filling as the second weight value.

[0120] Specifically, assume that the first water inflow is 100 ml and the second water inflow is 200 ml. Then, after the two water fillings, the total water volume in the cooking device is 300 ml, that is, M2 + M1 is equal to 300. In the ideal case, the measured weight value of 300 ml is 300 g, that is, N2 is equal to 300. At this time, the second correction coefficient obtained by the above formula is 1, that is, no correction of the water inflow is required.

[0121] If the actual water inflow is different from the second water inflow, then N2 is not equal to 300, P2 is not 1, and the water inflow needs to be corrected.

[0122] By comparing the correction coefficients multiple times through linear error correction, errors can be effectively avoided, making the finally obtained target correction coefficient more accurate.

[0123] Embodiment Seven

[0124] In some embodiments of the present invention, determining the target correction coefficient according to the first correction coefficient and the second correction coefficient specifically includes:

[0125] When the absolute value of the difference between the first correction coefficient and the second correction coefficient is less than a preset threshold, the average of the first correction coefficient and the second correction coefficient is determined as the target correction coefficient.

[0126] In the embodiments of the present invention, after obtaining the first correction coefficient and the second correction coefficient, the absolute value of the difference between the first correction coefficient and the second correction coefficient is further calculated, and it is determined whether the absolute value is greater than or equal to the preset threshold. If the absolute value is less than the preset threshold, it is considered that the error between the first correction coefficient and the second correction coefficient is small, and the accuracy rates of the first correction coefficient and the second correction coefficient are relatively high. At this time, the average value of the first correction coefficient and the second correction coefficient is calculated, and this average value is used as the target correction coefficient.

[0127] If the absolute value of the difference between the first correction coefficient and the second correction coefficient is greater than or equal to the preset threshold, it indicates that a large error has occurred between the first correction coefficient and the second correction coefficient. At this time, the obtained first correction coefficient and second correction coefficient are discarded, and the water inflow of the cooking device is re-controlled and re-calibrated.

[0128] By calculating the average value of multiple correction coefficients as the final target correction coefficient after determining that there is no large error between the multiple measured correction coefficients, it is beneficial to improve the accuracy of the target correction coefficient and ultimately improve the water inflow accuracy of the cooking device.

[0129] It can be understood that the preset threshold can be set according to the actual situation, such as set to 0.2, 0.25 or 0.15, etc. The embodiments of the present application do not limit this.

[0131] In some embodiments of the present invention, before controlling the water inflow of the cooking device, the control method further includes:

[0132] Controlling the cooking device to execute a preset self-check program, and controlling the cooking device to clear the weighed weight value.

[0133] In the embodiment of the present invention, before controlling the cooking device to intake water, that is, before starting to calibrate the correction coefficient, the cooking device is first controlled to execute a preset self-check program, that is, power-on self-check. Through the self-check program, it is judged whether components such as sensors, water pumps, and valves of the cooking device are normal. If normal, the calibration step can be executed. If abnormal, it may affect the calibration accuracy. At this time, corresponding prompts can be issued to inform the user that the self-check is abnormal.

[0134] Meanwhile, before water intake, the cooking device is controlled to drain water, and the weighed weight value is cleared to zero, preventing the residual water or the previously saved weight value in the cooking device from affecting the calibration accuracy.

[0135] Embodiment Nine

[0136] In a specific embodiment of the present invention, Figure 3 FIG. 3 shows the third flowchart of the control method of the cooking device according to the embodiment of the present invention. As Figure 3 shown, the control method of the cooking device includes:

[0137] Step 302, start self-check;

[0138] Step 304, clear the weight;

[0139] Step 306, intake M1 milliliters of water;

[0140] Step 308, weigh the weight value of N1 grams;

[0141] Step 310, calculate the correction coefficient P1 according to M1 and N1;

[0142] Step 312, perform secondary calibration to obtain P2;

[0143] Step 314, judge whether |P1 - P2|≥0.2 is satisfied; if yes, return to Step 304, otherwise enter Step 316;

[0144] Step 316, calculate the target correction coefficient;

[0145] In Step 316, the target correction coefficient P = (P1 + P2)÷2.

[0146] Among them, when starting calibration, first clear the weight. At this time, add M1 milliliters of water into the container. After waiting for the system to stabilize, weigh the weight value to obtain N1 grams. The system calculates the calibration coefficient P1 at this time:

[0147]

[0148] Then, perform secondary calibration and calculate the secondary calibration coefficient P2. If |P1 - P2| ≥ 0.2, it is considered that the error is large and the calibration fails, and it is recommended to perform calibration again. If |P1 - P2| < 0.2, determine the system target calibration coefficient P = (P1 + P2) ÷ 2, that is, calculate the sum of P1 and P2 and find the average value.

[0149] Among them, the steps of secondary calibration can be relative error correction. Figure 4 Fig. 4 shows a fourth flowchart of the control method of the cooking device according to an embodiment of the present invention. As Figure 4 shown, the steps of secondary calibration include:

[0150] Step 402, clear the weighing.

[0151] Step 404, fill in M2 milliliters of water.

[0152] Step 406, weigh a weight value of N2 grams.

[0153] Step 408, calculate the correction coefficient P2 according to M2 and N2.

[0154] Among them, when starting the second calibration, first clear the weight. At this time, add M2 milliliters of water to the container. After waiting for the system to stabilize, the weighed weight is N2 grams, and the system calculates the calibration coefficient P2 at this time:

[0155]

[0156] Among them, P2 is the second correction coefficient, M2 is the second water intake, and N2 is the second weight value.

[0157] The steps of secondary calibration can also be linear error correction. Figure 5 Fig. 5 shows a fifth flowchart of the control method of the cooking device according to an embodiment of the present invention. As Figure 5 shown, the steps of secondary calibration include:

[0158] Step 502, fill in M2 milliliters of water.

[0159] Step 504, weigh a weight value of N2 grams.

[0160] Step 506, calculate the correction coefficient P2 according to M2 and N2.

[0161] Among them, when starting the second calibration, add M2 milliliters of water to the container. M2 can be an integer multiple of M1. After waiting for the system to stabilize, the weighed weight is N2 grams, and the system calculates the calibration coefficient P2 at this time:

[0162]

[0163] Wherein, P2 is the second correction coefficient, M1 is the first water inflow, M2 is the second water inflow, and N2 is the second weight value.

[0164] Embodiment Ten

[0165] In some embodiments of the present invention, Figure 6 The structural block diagram of the cooking device according to an embodiment of the present invention is shown, as Figure 6 shown, the cooking device 600 includes: a memory 602, on which programs or instructions are stored; a processor 604, which is used to implement the steps of the control method of the cooking device provided in any of the above embodiments when executing the programs or instructions.

[0166] Specifically, control the water inlet of the cooking device, determine the correction coefficient according to the water inflow of the cooking device and the weight value corresponding to the water inflow; control the cooking device to work according to the correction coefficient.

[0167] Before the cooking device starts cooking work, first control the water inlet of the cooking device, and the water inlet can be carried out according to the water inflow corresponding to the preset water inlet program. At the same time, control the cooking device to weigh to obtain the weight value corresponding to the water inflow, and determine the correction coefficient according to the water inflow and the corresponding weight value.

[0168] Among them, for example, under ideal conditions, the cooking device fills water according to the set program. Assuming that 100 ml of water is filled, then the obtained water inlet weight should also correspond to 100 g. Therefore, the default water inlet can be set to 100 ml, and the corresponding weight value can be set to 100 g. After controlling the cooking device to fill 100 ml of water, if the obtained weight value is 110 g, it means that the water inlet is inaccurate due to water pressure reasons, and the actual water inlet is about 110 ml. Therefore, according to the water inflow and the weight value, the corresponding correction coefficient can be determined.

[0169] In the embodiment of the present invention, by controlling the water inlet of the cooking device before automatic cooking, determining the correction coefficient according to the water inflow and the corresponding weight value, and controlling the cooking device to automatically fill water during automatic cooking according to the correction coefficient, it is possible to avoid the water inlet error caused by external factors such as different water pressures, ensure that the water inflow matches the user's setting. On the one hand, it can improve the accuracy and reliability of the cooking device during automatic cooking, thereby improving the user experience. On the other hand, it can also prevent excessive water inlet caused by water inlet error and prevent liquid overflow during cooking, thereby ensuring the use safety of the cooking device.

[0170] Controlling the water inlet of the cooking device and determining the correction coefficient according to the water inflow of the cooking device and the weight value corresponding to the water inflow specifically includes:

[0171] Control the water inlet of the cooking device according to the first water inlet volume and the second water inlet volume respectively, and weigh the first weight value corresponding to the first water inlet volume and the second weight value corresponding to the second water inlet volume respectively; determine the first correction coefficient according to the first water inlet volume and the first weight value, and determine the second correction coefficient according to the second water inlet volume and the second weight value; determine the target correction coefficient according to the first correction coefficient and the second correction coefficient.

[0172] Control the water inlet of the cooking device according to the first water inlet volume and the second water inlet volume respectively. At the same time, weigh the actual water inlet volume after water inlet according to the first water inlet volume and the actual water inlet volume after water inlet according to the second water inlet volume respectively, determine the first correction coefficient and the second correction coefficient respectively, and determine the final target correction coefficient according to the two correction coefficients. By performing multiple water inlets and multiple weighings, and calculating respectively according to the data of each time to determine multiple correction coefficients, and finally further determining the final target correction coefficient according to the multiple correction coefficients, the error can be effectively avoided, so that the finally obtained target correction coefficient better conforms to the actual water inlet situation of the cooking device, thereby further improving the water inlet accuracy, improving the accuracy and reliability of the cooking device during automatic cooking, and thus improving the user experience.

[0173] Among them, it is possible to drain the water in the cooking device after the first water inlet according to the first water inlet volume and weighing the first water inlet, and then refill water according to the second water inlet volume for the second time and reweigh the second water inlet.

[0174] In some other embodiments, after the first water inlet according to the first water inlet volume and weighing the first water inlet, it is possible to directly refill water according to the second water inlet volume for the second time, weigh the total water inlet volume of the two water inlets, and use the total weight of the first water inlet and the second water inlet as the second weight value.

[0175] The second water inlet volume is the same as the first water inlet volume; or the second water inlet volume is N times the first water inlet volume, where N is a natural number greater than 1.

[0176] The second water inlet volume can be the same as the first water inlet volume. That is to say, water is inlet multiple times according to the same water inlet volume, weighed multiple times, and multiple correction coefficients are calculated, so as to reduce the error caused by different single water inlet situations, making the finally obtained target correction coefficient more accurate.

[0177] It can be understood that for the case where the first water inlet volume and the second water inlet volume are the same, it is also possible to refill water for the third time, the fourth time, and even the Xth time according to this water inlet volume and weigh them respectively. The more times of water inlet and weighing, the smaller the influence of the error caused by single sampling on the target correction coefficient determined according to this sampling.

[0178] In some other embodiments, the second water inflow is different from the first water inflow. Specifically, the second water inflow can be N times the first water inflow, where N is a natural number greater than 1. That is to say, the second water inflow is a positive integer multiple of the first water inflow. By setting the second water inflow to be different from the first water inflow, the water inlet error caused by external factors under different water inflows can be corrected, making the finally obtained target correction coefficient more accurate.

[0179] It can be understood that the first water inflow should be greater than the minimum measurement scale of the cooking device. For example, if the minimum water inflow of the cooking device is 1 ml and the minimum weighing accuracy is 1 g, then the first water inflow should be greater than 1 ml, such as set to 10 ml, etc. At the same time, the first water inflow and the second water inflow should be less than the maximum capacity of the cooking device.

[0180] Determine the first correction coefficient according to the first water inflow and the first weight value, specifically including:

[0181] Determine the first correction coefficient through the following formula:

[0182]

[0183] Wherein, P1 is the first correction coefficient, M1 is the first water inflow, and N1 is the first weight value.

[0184] In this technical solution, the first correction coefficient can be obtained through the above formula. Specifically, first calculate the absolute value of the difference between the first water inflow and the first weight value, and further calculate the ratio of the absolute value of the difference between the first water inflow and the first weight value to the first water inflow. The obtained ratio is the first correction coefficient.

[0185] Specifically, assume that the first water inflow is 100 ml. Since in the ideal case, the weight of 100 ml of water is 100 g, therefore, if the actual water inflow is consistent with the first water inflow when the water is inlet according to the first water inflow, then the first water inflow, that is, M1 is 100, and the first weight value, that is, N1 should also be 100. At this time, the first correction coefficient obtained by the above formula is 1, that is, no correction is required for the water inlet.

[0186] If the actual water inflow is different from the first water inflow and N1 is not equal to 100, then P1 is not 1 and correction is required for the water inlet.

[0187] When the second water inflow is N times the first water inflow, before controlling the cooking device to inlet water according to the second water inflow, the control method further includes:

[0188] Control the cooking device to drain water and clear the weighed weight value to zero;

[0189] Determine the second correction coefficient according to the second water inflow and the second weight value, specifically including:

[0190] The second correction coefficient is determined by the following formula:

[0191]

[0192] Wherein, P2 is the second correction coefficient, M2 is the second water inflow, and N2 is the second weight value.

[0193] Before the step of controlling the cooking device to intake water according to the second water inflow, control the cooking device to drain the water therein, that is, drain the first water intake, and at the same time clear the weighed weight value. That is to say, after the first water intake is carried out according to the first water inflow and the first water intake is weighed, drain the water in the cooking device at this time, then intake water again according to the second water inflow, and weigh the second water intake again.

[0194] At this time, calculate the second correction coefficient through the above formula. Specifically, first calculate the absolute value of the difference between the second water inflow and the second weight value, and further calculate the ratio of the absolute value of the difference between the second water inflow and the second weight value to the second water inflow, and calculate the difference between 1 and the obtained ratio, that is, the second correction coefficient.

[0195] Specifically, assume that the second water inflow is 200 ml. Since in the ideal case, the weight of 200 ml of water is 200 g, therefore, if the actual water inflow is consistent with the second water inflow when intaking water according to the second water inflow, then the second water inflow, that is, M2 is 200, and the second weight value, that is, N2 should also be 200. At this time, the second correction coefficient obtained by the above formula is 1, that is, no correction of the water intake is required.

[0196] If the actual water inflow is different from the second water inflow and N2 is not equal to 200, then P2 is not 1 and correction of the water intake is required.

[0197] By comparing the correction coefficients multiple times through the relative error correction method, errors can be effectively avoided, making the finally obtained target correction coefficient more accurate.

[0198] When the second water inflow is N times the first water inflow, determining the second correction coefficient according to the second water inflow and the second weight value specifically includes:

[0199] The second correction coefficient is determined by the following formula:

[0200]

[0201] Wherein, P2 is the second correction coefficient, M1 is the first water inflow, M2 is the second water inflow, and N2 is the second weight value.

[0202] Since the water from the first water inlet, i.e., the water volume of the first water inlet, was not drained before the second water inlet, that is, after the first water inlet was carried out according to the first water inlet volume and the water of the first water inlet was weighed, the second water inlet was directly carried out according to the second water inlet volume, and the total water inlet volume of the two water inlets was weighed, and the total weight of the first water inlet and the second water inlet was used as the second weight value.

[0203] Specifically, assuming that the first water inlet volume is 100 ml and the second water inlet volume is 200 ml, then after the two water inlets, the total water volume in the cooking device is 300 ml, that is, M2 + M1 is equal to 300. In an ideal situation, the measured weight value of 300 ml is 300 g, that is, N2 is equal to 300. At this time, the second correction coefficient obtained by the above formula is 1, that is, no correction is required for the water inlet.

[0204] If the actual water inlet volume is different from the second water inlet volume, then N2 is not equal to 300, P2 is not 1, and correction is required for the water inlet.

[0205] By comparing the correction coefficients multiple times through the method of linear error correction, errors can be effectively avoided, making the finally obtained target correction coefficient more accurate.

[0206] Determining the target correction coefficient according to the first correction coefficient and the second correction coefficient specifically includes:

[0207] When the absolute value of the difference between the first correction coefficient and the second correction coefficient is less than the preset threshold, the average of the first correction coefficient and the second correction coefficient is determined as the target correction coefficient.

[0208] After obtaining the first correction coefficient and the second correction coefficient, further calculate the absolute value of the difference between the first correction coefficient and the second correction coefficient, and judge whether the absolute value is greater than or equal to the preset threshold. If the absolute value is less than the preset threshold, it is considered that the error between the first correction coefficient and the second correction coefficient is small, and the accuracy of the first correction coefficient and the second correction coefficient is relatively high. At this time, calculate the average value of the first correction coefficient and the second correction coefficient, and use this average value as the target correction coefficient.

[0209] If the absolute value of the difference between the first correction coefficient and the second correction coefficient is greater than or equal to the preset threshold, it means that a large error has occurred between the first correction coefficient and the second correction coefficient. At this time, discard the obtained first correction coefficient and the second correction coefficient, and re-control the water inlet of the cooking device and re-perform calibration.

[0210] By calculating the average value of multiple correction coefficients as the final target correction coefficient after determining that there is no large error between the multiple measured correction coefficients, it is beneficial to improve the accuracy of the target correction coefficient and ultimately improve the water inlet precision of the cooking device.

[0211] It can be understood that the preset threshold can be set according to the actual situation, such as being set to 0.2, 0.25 or 0.15, etc. The embodiments of the present application do not limit this.

[0212] Before controlling the cooking device to intake water, the control method further includes:

[0213] Controlling the cooking device to execute a preset self-checking program, and controlling the cooking device to clear the weighed weight value.

[0214] Before controlling the cooking device to intake water, that is, before starting to calibrate the correction coefficient, first control the cooking device to execute a preset self-checking program, that is, power-on self-check. By the self-checking program, it is judged whether components such as the sensors, water pumps, and valves of the cooking device are normal. If normal, the calibration step can be executed. If abnormal, it may affect the calibration accuracy. At this time, corresponding prompts can be issued to inform the user that the self-check is abnormal.

[0215] Meanwhile, before water intake, control the cooking device to drain water and clear the weighed weight value to prevent the residual water in the cooking device or the previously saved weight value from affecting the calibration accuracy.
