[0049] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0050] Figure 1 This is a flow chart of a cooking control method provided by an embodiment of the present invention. This embodiment is applicable to the automatic adjustment and control of cooking parameters during the cooking process. The method can be executed by a processor in a cooking appliance, such as an oven or a steam-bake combination machine. Figure 1 As shown, the cooking control method specifically includes the following steps:

[0051] S101. Obtain the current weight of the ingredients at the current moment, and calculate the weight difference between the current weight of the ingredients and the weight of the basic ingredients at the previous moment.

[0052] The current moment is separated from the previous moment by a preset time interval. During the cooking process, the weight of the ingredients can be obtained at the preset time interval and the cooking control method of this embodiment can be executed. The weight of the ingredients obtained at the current moment is recorded as the current ingredient weight, and the weight of the ingredients obtained at the previous moment is recorded as the basic ingredient weight.

[0053] The specific value of the preset time can be set as needed and is not limited in the embodiment of the present invention. It is sufficient to ensure that the weight of the ingredients is obtained at least once during the cooking process. For example, the preset time can be 5 minutes, and the weight of the ingredients is obtained every 5 minutes after the cooking starts.

[0054] For example, the weight of the ingredients can be obtained using a weight sensor. Specifically, the weight sensor can use a Wheatstone bridge circuit to achieve weight measurement. A Wheatstone bridge (also known as a single-arm bridge) is an instrument that can accurately measure resistance and convert changes in resistance into weight output, enabling the acquisition of ingredient weight. For example, using an oven as an example, a weight sensor can be placed on a layered partition. After placing the ingredients, the weight sensor can measure and output the weight.

[0055] S102: Determine whether the weight difference is within a first preset range. If so, execute S103; otherwise, execute S104.

[0056] The first preset range can be determined based on experience, the weight changes of different ingredients during cooking, and other factors. The present invention does not limit its specific range. The first preset range is specifically a threshold range. If the weight difference exceeds the first preset range, it indicates that the weight of the ingredients has changed significantly. Continuing to cook according to the current cooking parameters, such as cooking temperature and cooking time, may result in overcooking, affecting the cooking effect. Adjustment of the cooking parameters is necessary. Otherwise, cooking can continue according to the current cooking parameters. See S103 and S104 for details.

[0057] S103: Continue cooking according to the basic cooking parameters at the last moment.

[0058] S104: Adjust the subsequent cooking parameters corresponding to the current moment based on the basic cooking parameters corresponding to the previous moment, and continue cooking according to the subsequent cooking parameters.

[0059] The basic cooking parameters include a basic cooking time and a basic cooking temperature. Specifically, the basic cooking time is the remaining cooking time from the previous moment to the end of cooking, and the basic cooking temperature is the cooking temperature corresponding to the previous moment. Cooking is performed at this basic cooking temperature at least from the previous moment to the current moment. Accordingly, the subsequent cooking parameters include a subsequent cooking temperature and a subsequent cooking time. The subsequent cooking time is the remaining cooking time from the current moment to the end of cooking, and the subsequent cooking temperature is the cooking temperature corresponding to the current moment. Cooking is performed at this subsequent cooking temperature at least from the current moment to the next moment.

[0060] Specifically, if the weight difference is within a first preset range, cooking continues according to the basic cooking parameters at the previous moment. In other words, starting from the current moment and continuing until at least the next moment after the preset time, the subsequent cooking temperature remains unchanged at the previous moment's basic cooking temperature. From the current moment until the end of the cooking moment, the remaining cooking time is the difference between the basic cooking time and the preset time. For example, assuming the basic cooking temperature at the previous moment was 200°C and the basic cooking time was 20 minutes, at the current moment (5 minutes after the previous moment), if the weight difference is within the first preset range, the subsequent cooking temperature remains unchanged at 200°C and the subsequent cooking time is 15 minutes (because 5 minutes have passed since the current moment, the remaining cooking time is 15 minutes, and at this time, no adjustment has been made to the basic cooking time).

[0061] Specifically, if the weight difference exceeds a first preset range, the subsequent cooking parameters corresponding to the current moment are adjusted based on the basic cooking parameters corresponding to the previous moment. In other words, the cooking temperature is adjusted based on the basic cooking temperature at the previous moment, and the adjusted cooking temperature is used as the subsequent cooking temperature, and cooking is continued at this cooking temperature until at least the next moment. Based on the basic cooking time at the previous moment, the theoretically remaining cooking time at the current moment is the basic cooking time minus the preset time. However, since the weight difference exceeds the first preset range, to avoid overcooking, the cooking time may be adjusted based on this remaining cooking time, and the adjusted cooking time may be used as the remaining cooking time from the current moment to the end of cooking. For example, assuming that the basic cooking temperature corresponding to the previous moment is 200° and the basic cooking time is 20 minutes, at the current moment (5 minutes after the previous moment), if the weight difference exceeds the first preset range, in order to avoid overcooking, the cooking temperature can be appropriately lowered, for example, the subsequent cooking temperature is adjusted to 198°, and cooking is continued at 198°, at least until the next moment; in addition, the subsequent cooking time can be appropriately reduced, that is, the cooking time is reduced on the basis of 15 minutes (obtained by subtracting the preset time 5 minutes from the basic cooking time 20 minutes, so the subsequent cooking time is adjusted on the basis of the basic cooking time), for example, the remaining cooking time from the current moment to the end of cooking is adjusted to 14.5 minutes, that is, the subsequent cooking time corresponding to the current moment is adjusted to 14.5 minutes.

[0062] It should be noted that when adjusting the subsequent cooking parameters corresponding to the current moment based on the basic cooking parameters corresponding to the previous moment, at least one of the basic cooking time and the basic cooking temperature can be adjusted, that is, only the basic cooking temperature can be adjusted or only the basic cooking time can be adjusted. In addition, the basic cooking temperature and the basic cooking time can also be adjusted at the same time. Those skilled in the art can choose the adjustment method according to actual conditions.

[0063] The embodiment of the present invention obtains the current weight of the ingredients at the current moment during the cooking process and calculates the weight difference between the current weight of the ingredients and the basic weight of the ingredients at the previous moment. When the weight difference is within a first preset range, cooking continues according to the basic cooking parameters at the previous moment. When the weight difference exceeds the first preset range, the subsequent cooking parameters corresponding to the current moment are adjusted based on the basic cooking parameters corresponding to the previous moment. This can improve the cooking effect of automatic cooking and avoid overcooking.

[0064] Figure 2 This is a flow chart of another cooking control method provided by an embodiment of the present invention, which further supplements the cooking control method of the automatic cooking process based on the above embodiment. Figure 2 As shown, the cooking control method may include the following steps:

[0065] S201: Obtain the initial weight of the ingredients to be cooked, and compare the initial weight with the reference weight of the ingredients in the cooking recipe.

[0066] The ingredients in the cooking recipe are consistent with the ingredients to be cooked, and the cooking recipe includes data such as a reference ingredient weight and reference cooking parameters corresponding to the reference ingredient weight. Cooking the ingredients with the reference ingredient weight according to the reference cooking parameters results in a better cooking effect. A cooking appliance with an automatic cooking function stores a recipe database that can record cooking recipes corresponding to a variety of ingredients. During automatic cooking, a user can select a cooking recipe based on the ingredients to be cooked, thereby using data such as the reference ingredient weight corresponding to the cooking recipe.

[0067] The initial weight of the ingredients refers to the weight of the ingredients before cooking. Specifically, before cooking begins, or after the ingredients are added, the initial weight of the ingredients to be cooked can be obtained using a weight sensor. The initial weight of the ingredients can be compared with the reference weight of the ingredients in the cooking recipe, and the user can choose whether to adjust the reference cooking parameters in the cooking recipe. See S202 for details.

[0068] S202. If the initial difference between the initial ingredient weight and the reference ingredient weight is within a second preset range, the reference cooking parameters in the cooking recipe are determined as the initial cooking parameters of the ingredients to be cooked; otherwise, the reference cooking parameters are adjusted according to the initial difference, and the adjusted reference cooking parameters are determined as the initial cooking parameters of the ingredients to be cooked.

[0069] The second preset range can be a relatively small range, and the embodiment of the present invention does not limit its specific value. Specifically, if the initial difference is within the second preset range, it indicates that the weight of the ingredients cooked by the user is substantially consistent with the weight of the ingredients in the cooking recipe. In this case, cooking according to the reference cooking parameters in the cooking recipe can achieve a good cooking effect, and the reference cooking parameters do not need to be adjusted. If the initial difference exceeds the second preset range, it indicates that the weight of the ingredients cooked by the user is significantly different from the weight of the ingredients in the cooking recipe. In this case, the reference cooking parameters in the cooking recipe can be adaptively adjusted and the adjusted reference cooking parameters can be used as the initial cooking parameters for the ingredients to be cooked.

[0070] The reference cooking parameters include a reference cooking time and a reference cooking temperature, and the initial cooking parameters include an initial cooking time and an initial cooking temperature. Specifically, if the initial difference is within a second preset range, the initial cooking time is equal to the reference cooking time, and the initial cooking temperature is equal to the reference cooking temperature. If the initial difference is outside the second preset range, the initial cooking time is greater than / less than the reference cooking time, and the initial cooking temperature is greater than / less than the reference cooking temperature. The adjustment direction (increase / decrease) and adjustment range of the reference cooking parameters can be set based on the sign and magnitude of the initial difference.

[0071] In a specific embodiment, if the initial difference exceeds the second preset range and the initial food weight is greater than the reference food weight, the reference cooking temperature may be increased and / or the reference cooking time may be increased; if the initial difference exceeds the second preset range and the initial food weight is less than the reference food weight, the reference cooking temperature may be kept unchanged and the reference cooking time may be reduced.

[0072] Specifically, if the initial ingredient weight is greater than the reference ingredient weight, and the difference between the two exceeds a second preset range, at least one of the reference cooking temperature and the reference cooking time may be increased to ensure that the food is cooked thoroughly. If the initial ingredient weight is less than the reference ingredient weight, and the difference between the two exceeds the second preset range, the reference cooking temperature may be maintained to ensure the required cooking temperature for the ingredients, while the reference cooking time may be reduced to avoid overcooking and affecting the cooking effect. For example, the initial cooking time / initial cooking temperature may be adjusted proportionally based on the reference cooking time / reference cooking temperature according to the size of the initial difference.

[0073] Before cooking begins, a first preset range may be determined based on the initial weight of the ingredients, as detailed in S203 .

[0074] S203: Determine a first preset range according to the initial food weight.

[0075] According to the above embodiments, the first preset range is a standard for judging the degree of weight change of ingredients during the cooking process. Determining the first preset range based on the initial weight of the ingredients can improve the rationality of the judgment standard and ensure the accuracy of subsequent judgment results.

[0076] Specifically, determining the first preset range according to the initial food weight may include the following steps:

[0077] First, determine the weight range into which the initial ingredient weight falls.

[0078] Then, according to the correspondence between the preset weight range and the first preset coefficient, and the weight range to which the initial food weight belongs, the first preset coefficient corresponding to the initial food weight is determined.

[0079] Finally, a first preset range is calculated based on the initial food weight and the first preset coefficient, wherein the absolute values ​​of the minimum and maximum values ​​in the first preset range are both equal to the product of the first preset coefficient and the initial food weight.

[0080] The weight range can be divided as follows: The weight of ingredients that a cooking appliance can cook is limited. The weight range from zero to the maximum ingredient weight can be divided into different weight ranges (weight intervals). For example, the weight ranges may include (0, A), (A, B), (B, C), and (C, D), where D represents the maximum ingredient energy. Furthermore, A = 25% D, B = 50% D, and C = 75% D can be set. It should be noted that the number of weight ranges can be divided according to actual needs, and the embodiments of the present invention do not limit this. The above is only an example.

[0081] Furthermore, the first preset coefficient corresponds to the weight range one by one. After determining the initial weight of the food, it is possible to first determine to which weight range the initial weight of the food belongs, and then determine the first preset coefficient corresponding to the initial weight of the food, and calculate the first preset range based on the initial weight of the food and the first preset coefficient. Specifically, the absolute values ​​of the minimum and maximum values ​​in the first preset range are equal to the product of the initial weight of the food and the first preset coefficient. Exemplarily, if the initial weight of the food X belongs to the weight range of (0, A), and the first preset coefficient corresponding to the weight range is a, then the first preset range is (-aX, aX).

[0082] Furthermore, the larger the weight value in the optional weight range, the larger the first preset coefficient corresponding to that weight range. This setting can make the first preset range corresponding to heavier ingredients larger, and the first preset range corresponding to lighter ingredients smaller, ensuring that cooking parameters can be adjusted when necessary and avoiding frequent adjustments of cooking parameters. For example, for heavier ingredients, their weight varies greatly, and by setting a larger first preset range, frequent adjustments of cooking parameters can be avoided. For example, the first preset coefficients corresponding to the above four weight ranges can be 0.5%, 0.8%, 1.0%, and 1.2%, respectively.

[0083] Next, you can refer to the above embodiment, obtain the weight of the ingredients (i.e., the current weight of the ingredients) every preset time, and compare it with the weight of the ingredients at the previous moment (i.e., the basic ingredient weight), and choose whether to adjust the cooking parameters based on the comparison results. See S204-S207 for details. The similarities with the above embodiment will not be repeated here.

[0084] S204: Obtain the current weight of the ingredients at the current moment, and calculate the weight difference between the current weight of the ingredients and the weight of the basic ingredients at the previous moment.

[0085] S205: Determine whether the weight difference is within a first preset range. If so, execute S206; otherwise, execute S207.

[0086] S206: Continue cooking according to the basic cooking parameters at the last moment.

[0087] S207: Adjust the subsequent cooking parameters corresponding to the current moment based on the basic cooking parameters corresponding to the previous moment, and continue cooking according to the subsequent cooking parameters.

[0088] Specifically, the initial cooking parameters at the initial moment can be understood as the basic cooking parameters at the first previous moment. In other words, the basic cooking parameters at the previous moment include the initial cooking parameters at the initial moment. Among the initial cooking parameters, the initial cooking time is the total cooking time set at the initial moment, and the initial cooking temperature is the cooking temperature set at the initial moment. Starting from the initial moment, as the cooking time progresses, after the first preset time has passed, the weight change of the ingredients during this time period can be determined. Based on whether the weight change exceeds a first preset range, a determination is made as to whether the initial cooking parameters should be adjusted. Subsequently, starting from this moment, after the second preset time has passed, the weight change of the ingredients during this time period can be determined. Based on whether the weight change exceeds the first preset range, a determination is made as to whether the cooking parameters determined at the first preset time should be adjusted. And so on. At each current moment, the cooking parameters for the current moment and thereafter (i.e., subsequent cooking parameters) are determined based on the cooking parameters at the moment before the preset time and the degree of weight change. This achieves dynamic adjustment and updating of the cooking parameters, preventing inappropriate initial cooking parameter settings from affecting cooking results.

[0089] Furthermore, it is optional to adjust the subsequent cooking parameters corresponding to the current moment based on the basic cooking parameters corresponding to the previous moment, specifically: calculate the subsequent cooking temperature based on the basic cooking temperature and the second preset coefficient; and / or calculate the subsequent cooking time based on the basic cooking time, the preset time and the third preset coefficient.

[0090] Among them, the subsequent cooking temperature is the cooking temperature within the preset time from the current moment to the next moment. It can be understood that if the weight change at the next moment does not exceed the first preset range, the cooking temperature will continue to be maintained; the subsequent cooking time is the remaining cooking time from the current moment to the end of cooking. It can be understood that if the weight change at the next moment exceeds the first preset range, the remaining cooking time will be adjusted again based on the difference between the subsequent cooking time and the preset time.

[0091] The second and third preset coefficients are set to correspond to the weight range. Specifically, the second and third preset coefficients represent the degree of adjustment: a larger second preset coefficient indicates a greater degree of adjustment to the base cooking temperature; a larger third preset coefficient indicates a greater degree of adjustment to the difference between the base cooking time and the preset time.

[0092] For example, assuming the initial ingredient weight X falls within the weight range (0, A), the second preset coefficient b and the third preset coefficient c corresponding to this weight range, the base cooking temperature F, the base cooking time T, and the preset time t corresponding to the previous moment, if the current moment determines that the difference between the current ingredient weight and the base ingredient weight exceeds the first preset range, to avoid overcooking, the subsequent cooking temperature may be adjusted to (1-b)F and / or the subsequent cooking time may be adjusted to (1-c)T.

[0093] Furthermore, the larger the weight value within the selectable weight range, the larger the second and third preset coefficients corresponding to that weight range. This arrangement allows for a relatively large adjustment range for heavier ingredients and a relatively small adjustment range for lighter ingredients. This allows for a reasonable adjustment level based on the characteristics of the ingredients, avoiding excessive adjustments that could affect cooking results. For example, the second preset coefficients corresponding to the four weight ranges mentioned above could be 0.1%, 0.3%, 0.5%, and 0.6%, respectively.

[0094] It is understandable that the weight of the ingredients will change during the cooking process, either increasing (for example, when cooking pasta, it will increase as the water content increases) or decreasing (for example, when cooking meat or vegetables, it will decrease as the fat or water content is lost), but the degree of weight change will become smaller and smaller. After a certain moment, the weight difference within the preset time will be within the first preset range, and the cooking parameters set at that moment will remain unchanged until the cooking time countdown is completed and cooking is completed.

[0095] In summary, the embodiment of the present invention determines the first preset range based on the weight of the initial ingredients, and adjusts the basic cooking parameters to different degrees based on ingredients of different weights, which can further optimize the cooking effect.

[0096] Based on the above embodiment, the optional cooking control method also includes the following steps: obtaining the actual cooking temperature; comparing the actual cooking temperature with the set cooking temperature, and pausing heating when the actual cooking temperature is greater than or equal to the set cooking temperature.

[0097] During the cooking process, the desired cooking temperature may vary at different times. Therefore, the set cooking temperature specifically refers to the cooking temperature that should be reached at the time the actual cooking temperature is acquired. The actual cooking temperature can be acquired via a temperature sensor. When the actual temperature is greater than or equal to the set temperature, the heating device in the cooking appliance is controlled to suspend heating to prevent the food from burning. For example, the actual cooking temperature can be measured in real time or at regular intervals, although this is not limited in this embodiment of the present invention.

[0098] Figure 3 This is a specific flow chart of the cooking control method provided by an embodiment of the present invention. Figure 3 As shown, taking the steam-bake combination machine as an example, the system of the steam-bake combination machine is initialized after it is turned on. Then the user selects the recipe corresponding to the ingredients to be cooked and puts the ingredients to be cooked into the chamber. The system will initialize the recipe temperature and time according to the initial weight of the ingredients (refer to the above S201-S202). During the cooking process, the weight of the ingredients will continue to be collected. For example, the weight of the ingredients can be collected every 5 minutes, and the temperature and time of the recipe can be selectively updated according to the change in the weight of the ingredients (refer to the above S204-S207) until the cooking countdown ends and the cooking time is reached. In addition, during the cooking process, the cooking temperature can also be collected. For example, the cooking temperature is collected every 10ms. If the cooking temperature exceeds the temperature set in the recipe, the heating device is controlled to stop heating to avoid burning the food.

[0099] Based on the same inventive concept, an embodiment of the present invention further provides a cooking control device. Figure 4 FIG. 1 is a structural diagram of a cooking control device provided by an embodiment of the present invention. Figure 4 As shown, the cooking control device includes a calculation module 301, a judgment module 302, and a control module 303. The calculation module 301 is used to obtain the current ingredient weight at the current moment and calculate the weight difference between the current ingredient weight and the basic ingredient weight at the previous moment. The judgment module 302 is used to determine whether the weight difference is within a first preset range. The control module 303 is used to continue cooking according to the basic cooking parameters at the previous moment if the weight difference is within the first preset range, or to adjust the subsequent cooking parameters corresponding to the current moment based on the basic cooking parameters corresponding to the previous moment if the weight difference exceeds the first preset range, and continue cooking according to the subsequent cooking parameters. The basic cooking parameters include a basic cooking time and a basic cooking temperature. A preset time interval is set between the current moment and the previous moment. During the cooking process, the ingredient weight is obtained every preset time interval.

[0100] The cooking control device provided in the embodiment of the present invention has the same beneficial effects as the cooking control method provided in the above embodiment, which will not be described in detail here.

[0101] On the basis of the above-mentioned embodiments, the optional cooking control device further comprises a comparison module configured to obtain an initial food material weight of the food material to be cooked, and compare the initial food material weight with a reference food material weight in the cooking recipe; the control module 303 is further configured to determine the reference cooking parameter in the cooking recipe as an initial cooking parameter of the food material to be cooked when an initial difference between the initial food material weight and the reference food material weight is within a second preset range; otherwise, adjust the reference cooking parameter according to the initial difference, and determine the adjusted reference cooking parameter as the initial cooking parameter of the food material to be cooked. The reference cooking parameter comprises a reference cooking time and a reference cooking temperature, and the initial cooking parameter comprises an initial cooking time and an initial cooking temperature.

[0102] Further, the control module 303 is specifically configured to increase the reference cooking temperature and / or increase the reference cooking time when the initial difference exceeds the second preset range and the initial food material weight is greater than the reference food material weight; and keep the reference cooking temperature unchanged and decrease the reference cooking time when the initial difference exceeds the second preset range and the initial food material weight is less than the reference food material weight.
