Description

Technical Field

[0001] This invention relates to the field of cooking, and more specifically to a control method, control system, electronic equipment, and medium for a steam oven. Background Technology

[0002] In existing steam ovens, the rear fan turns on during cooking, which helps to quickly distribute heat from the heating element within the machine, resulting in a more even internal temperature. However, in actual use, the rear fan operates at a fixed speed. While this strategy is simple to control, it is not suitable for most scenarios. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology where the fan speed is fixed. This strategy is simple to control but not applicable to most scenarios. The present invention provides a control method, control system, electronic equipment and medium for a steam oven.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] As a first aspect of the present invention, the present invention provides a control method for a steam oven, comprising:

[0006] Determine the current weight of the food in the steam oven and the weight setting it belongs to;

[0007] Determine the corresponding wind speed level based on the weight level;

[0008] The steam oven is controlled to operate according to the corresponding fan speed setting;

[0009] The weight setting is positively correlated with the wind speed setting.

[0010] Optionally, the control method further includes:

[0011] Determine whether the food is frozen or not;

[0012] When the food is frozen, determine the first fan speed setting based on the weight of the food.

[0013] When the food is not frozen, determine the second fan speed setting based on the weight of the food.

[0014] Among them, under the same weight setting, the first wind speed setting is greater than the second wind speed setting.

[0015] Optionally, the control method further includes:

[0016] Monitor the heating duration of the steam oven and the center temperature of the steam oven cavity;

[0017] If the heating duration is less than a first preset time and the center temperature is less than a first preset temperature, then the food is determined to be in a frozen state.

[0018] Otherwise, the food is determined to be in a non-frozen state.

[0019] Optionally, after determining the second fan speed setting based on the weight of the food, the process includes:

[0020] If the current weight of the food decreases, and the current weight is less than the first preset weight, and the difference between the initial weight and the current weight of the food is greater than the second preset weight, then the wind speed will be adjusted to the third wind speed setting.

[0021] The third wind speed setting is lower than the second wind speed setting;

[0022] Optionally, if the current weight of the food increases and the increase in current weight is greater than a third preset weight, then it is detected whether the steam oven has a door opening / closing action. If a door opening / closing action exists, then at the beginning of each door closing, the closing duration of each door closing is determined.

[0023] If the door closing time is less than the second preset time, then the fourth wind speed setting is determined according to the weight setting to which the current weight belongs.

[0024] The weight setting is positively correlated with the fourth wind speed setting, and at the same weight setting, the fourth wind speed setting is greater than the second wind speed setting.

[0025] Optionally, the step of determining the corresponding wind speed level based on the weight level specifically includes:

[0026] When the center temperature of the steam oven cavity is greater than the second preset temperature, the steam oven enters the heat preservation state and the temperature holding time is determined.

[0027] When the food is not frozen, if the temperature holding time is less than or equal to the third preset time, the original fan speed setting is maintained; if the temperature holding time is greater than the third preset time, the fifth fan speed setting is determined according to the weight setting.

[0028] When food is frozen, if the temperature holding time is less than or equal to the third preset time, the original fan speed setting is maintained. If the temperature holding time is greater than the third preset time but less than the fourth preset time, the sixth fan speed setting is determined based on the weight setting. If the temperature holding time is greater than the fourth preset time, the food is determined to be in a non-frozen state, and the temperature holding time is recalculated.

[0029] The weight setting is positively correlated with the fifth wind speed setting, and the weight setting is positively correlated with the sixth wind speed setting. Furthermore, at the same weight setting, the fifth wind speed setting is smaller than the sixth wind speed setting.

[0030] Optionally, the control method further includes:

[0031] In response to the center temperature being greater than a third preset temperature, and the temperature holding time being greater than a fifth preset time;

[0032] If the current wind speed setting is greater than the first preset wind speed setting, the current wind speed setting will be adjusted to the first preset wind speed setting; if the current wind speed setting is less than or equal to the first preset wind speed setting, the current wind speed setting will remain unchanged.

[0033] The fifth preset time is greater than the fourth preset time.

[0034] Optionally, the control method further includes:

[0035] After confirming that the weight of the food does not change after the door is closed, obtain the total time the steam oven is open and the duration of the door being closed.

[0036] If the total door opening time is less than the sixth preset time, the current wind speed setting remains unchanged;

[0037] If the total opening time is greater than or equal to the sixth preset time and the closing time is less than the seventh preset time, and if the current wind speed level is greater than or equal to the second preset wind speed level, then the current wind speed level is increased; if the current wind speed level is less than the second preset wind speed level, then the current wind speed level remains unchanged.

[0038] If the duration of the door closing is greater than or equal to the seventh preset time, the wind speed will be reduced back to the original wind speed.

[0039] Optionally, before the step of determining the current weight of the food in the steam oven and the weight setting to which the current weight belongs, the method further includes:

[0040] Obtain the initial weight of the food;

[0041] If the initial weight is less than the fourth preset weight, the wind speed setting is determined to be the seventh wind speed setting; otherwise, the wind speed setting is determined to be the eighth wind speed setting.

[0042] The eighth wind speed setting is greater than the seventh wind speed setting.

[0043] As a second aspect of the present invention, the present invention provides a control system for a steam oven.

[0044] The control system includes: a weight determination module, a fan speed setting determination module, and a steam oven operation module;

[0045] The weight determination module is used to determine the current weight of the food in the steam oven and the weight level to which the current weight belongs.

[0046] The wind speed setting determination module is used to determine the corresponding wind speed setting based on the weight setting.

[0047] The steam oven operation module is used to control the operation of the steam oven according to the corresponding fan speed setting.

[0048] As a third aspect of the present invention, the present invention provides an electronic device for a steam oven.

[0049] The electronic equipment of the steam oven includes: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the control method of the steam oven as described in any of the first aspects of the present invention.

[0050] As a fourth aspect of the present invention, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the control method of a steam oven according to any one of the first aspects of the present invention.

[0051] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of the present invention.

[0052] The positive and progressive effects of this invention are as follows:

[0053] The steam oven heats food at varying speeds based on its weight, ensuring even heating of foods of different weights. This versatility makes it suitable for various scenarios and provides a superior user experience. It can also adaptively adjust the airflow based on food weight, speeding up the cooking process while preventing food from tipping over. Furthermore, it can increase the fan speed to facilitate rapid heat dissipation, especially in situations like when the door is open. The motor operates efficiently in different environments without overheating, extending its lifespan; simultaneously, it accelerates the cooking process and ensures optimal results.

[0064] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0065] Example 1

[0066] Please see Figure 1 As an embodiment 1 of the present invention, the present invention provides a control method for a steam oven, comprising:

[0067] S1. Determine the current weight of the food in the steam oven and the weight setting to which the current weight belongs;

[0068] S2. Determine the corresponding wind speed setting based on the weight setting;

[0069] S3. Control the operation of the steam oven according to the corresponding fan speed setting;

[0070] Among them, the weight setting is positively correlated with the wind speed setting.

[0071] In this embodiment, the steam oven's fan speed is determined based on the weight of the food. Foods with higher weights have faster fan speeds, allowing them to be heated more evenly. This enables the heating of foods with different weights, improving the user experience.

[0072] Please see Figure 2 In an optional embodiment, step S2 is further included before:

[0073] S4. Determine whether the food is frozen or not;

[0074] Step S2 specifically includes:

[0075] S401. When the food is frozen, determine the first preset fan speed setting based on the weight of the food.

[0076] S402. When the food is not frozen, determine the second fan speed setting based on the weight of the food.

[0077] Among them, under the same weight setting, the first wind speed setting is greater than the second wind speed setting.

[0078] In this embodiment, there will also be frozen and non-frozen foods. Under the same weight setting, the first fan speed setting corresponding to frozen foods is greater than the second fan speed setting corresponding to non-frozen foods, so that the foods can be thawed quickly. This can meet the cooking needs of foods in different states (i.e., frozen and non-frozen) and improve the user experience.

[0079] Please see Figure 3 In an optional embodiment, step S4 specifically includes:

[0080] S403. Monitor the heating duration of the steam oven and the center temperature of the steam oven cavity;

[0081] S40301. Determine whether the heating duration is less than the first preset time and whether the center temperature is less than the first preset temperature; if yes, proceed to step S40302; if no, proceed to step S40303.

[0082] S40302. Confirm that the food is frozen;

[0083] S40303, Determine that the food is not frozen.

[0084] In this embodiment, since the temperature rise of frozen food is necessarily less than that of non-frozen food in the initial stage of heating, by monitoring the heating duration and the core temperature, it can be determined whether the food is frozen or non-frozen (it should be noted that the core temperature can be corrected by the probe temperature set on the temperature probe in the steam oven to obtain the core temperature). If it is less than the first preset temperature, it means that the core temperature of the food is not high enough and cannot meet the standard for thawing food.

[0085] If the heating duration is less than the first preset time, or the center temperature is less than the first preset temperature, then the food is determined to be in a non-frozen state.

[0086] In this embodiment, it is possible to accurately determine whether the food is frozen or not, avoiding errors in food status identification and improving the user experience.

[0087] Please see Figure 4 In an optional embodiment, after step S402, the following steps are included:

[0088] S40201. Determine if the current weight of the food has decreased; if yes, proceed to S40202; if no, proceed to step S40211.

[0089] S40202. Determine whether the current weight is less than the first preset weight, and whether the difference between the initial weight of the food and the current weight is greater than the second preset weight; if yes, proceed to step S40203; if no, proceed to step S40204.

[0090] S40203, Adjust the wind speed to the third wind speed setting;

[0091] S40204, Keep the fan speed setting unchanged.

[0092] The third wind speed setting is lower than the second wind speed setting.

[0093] In the above embodiments, if the current weight of the food decreases and is less than a first preset weight, it can be determined that the food has lost moisture during the cooking process. If the difference between the initial weight and the current weight of the food is greater than a second preset weight (the second preset weight can be 0.5 times the initial weight), it indicates that the food has lost more moisture than the second preset weight during the cooking process, from the moment it was placed in the steam oven.

[0094] Adjusting the fan speed to the third setting will help retain the moisture in the food, preventing it from drying out and affecting its texture.

[0095] In an optional embodiment, after step S402, the following steps are included:

[0096] S40211. Determine whether the current weight of the food has increased, and whether the increase in the current weight is greater than the third preset weight; if so, proceed to step S40212.

[0097] S40212. Check if the steam oven door is opening or closing.

[0098] S40213. If there is a door opening and closing action, determine the closing duration for each closing action at the beginning of each closing action.

[0099] S40214. Determine whether the door closing time is less than the second preset time; if so, proceed to step S40215.

[0100] S40215. Determine the fourth wind speed setting based on the current weight's weight setting.

[0101] Among them, the weight setting is positively correlated with the fourth wind speed setting, and under the same weight setting, the fourth wind speed setting is greater than the second wind speed setting.

[0102] In this embodiment, when the current weight of the food increases, and this increase exceeds a third preset weight, it can be determined that some ingredients have been added or some sauce has been applied (rather than simply adding salt). When the door-closed duration is less than a second preset time, it can be determined that the temperature inside the steam oven has decreased, requiring a higher fourth fan speed setting compared to the second. This accelerates heat circulation within the steam oven, thereby ensuring optimal cooking results.

[0103] Please see Figure 5 In an optional embodiment, step S2 specifically includes:

[0104] S201. Determine whether the center temperature of the steam oven cavity is greater than the second preset temperature. If so, proceed to step S202.

[0105] S202. Determine that the steam oven has entered the heat preservation state, and determine whether the center temperature of the steam oven cavity is greater than the second preset temperature. If so, proceed to step S203.

[0106] S203. Determine the temperature holding time;

[0107] S20401. When the food is not frozen, determine whether the temperature holding time is less than or equal to the third preset time; if yes, proceed to step S20402; if no, proceed to step S20403.

[0108] S20402, Maintain the original fan speed setting;

[0109] S20403. Determine the fifth wind speed setting based on the weight setting.

[0110] S20411. When the food is frozen, determine whether the temperature holding time is less than or equal to the third preset time. If yes, proceed to step S20412. Otherwise, determine whether the temperature holding time is greater than the third preset time and less than the fourth preset time.

[0111] If the temperature holding time is greater than the third preset time and less than the fourth preset time, then execute step S20413; otherwise, determine whether the temperature holding time is greater than the fourth preset time.

[0112] If the temperature holding time is greater than the fourth preset time, then proceed to step S20414;

[0113] S20412, Maintain the original fan speed setting;

[0114] S20413. Determine the sixth wind speed setting based on the weight setting;

[0115] S20414. Recalculate the temperature holding time to confirm that the food has become non-frozen.

[0116] Among them, the weight setting is positively correlated with the fifth wind speed setting, and the weight setting is positively correlated with the sixth wind speed setting. Moreover, under the same weight setting, the fifth wind speed setting is lower than the sixth wind speed setting.

[0117] In the heat preservation mode, the food is in a non-frozen state, and the temperature is maintained for less than or equal to the third preset time. This ensures that the food is heated to the center. Switching to the fifth fan speed setting will prevent the food from losing moisture.

[0118] If the temperature holding time is longer than the fourth preset time when the food is frozen, it is determined that the food has thawed and can be turned into a non-frozen state, and a new temperature holding time is recalculated.

[0119] In an optional embodiment, the control method further includes:

[0120] If the center temperature is greater than the third preset temperature and the temperature holding time is greater than the fifth preset time, then step S206 is executed.

[0121] S206. Determine whether the current wind speed setting is greater than the first preset wind speed setting; if yes, proceed to step S20601; if no, proceed to step S20602.

[0122] S20601. Adjust the current wind speed setting to the first preset wind speed setting;

[0123] S20602 maintains the current wind speed setting.

[0124] The fifth preset time is greater than the fourth preset time.

[0125] In this embodiment, if the center temperature is greater than the third preset temperature and the temperature holding time is greater than the fifth preset time, and the fan speed is higher than the first preset setting, moisture will be lost from the food surface, resulting in a poor texture. This embodiment prevents the food surface from drying out, thus ensuring the food's texture.

[0126] Please see Figure 6 In an optional embodiment, the control method further includes:

[0127] S5. After confirming that the weight of the food does not change after the door is closed, obtain the total opening time and closing time of the steam oven.

[0128] S501. Determine whether the total door opening time is less than the sixth preset time; if yes, proceed to S502; if no, proceed to S503.

[0129] S502, the current wind speed setting remains unchanged;

[0130] S503. Determine whether the closing time is less than the seventh preset time; if yes, proceed to step S50301; if no, proceed to step S50304.

[0131] S50301. Determine whether the current wind speed setting is greater than or equal to the second preset wind speed setting; if yes, proceed to step S50302; if no, proceed to step S50303.

[0132] S50302, Increase the current wind speed setting;

[0133] S50303: The current wind speed setting remains unchanged;

[0134] S50304. If the duration of the door being closed is greater than or equal to the seventh preset time, the wind speed will be reduced back to the original wind speed after the speed was increased.

[0135] In this embodiment, if the total door opening time is greater than or equal to the sixth preset time, it means that a significant amount of heat is lost from the steam oven. In this case, the current fan speed is increased to maintain the temperature inside the steam oven. If the current fan speed is less than the second preset fan speed, it means that the food surface may lose moisture, so the fan speed is not increased.

[0136] When the door remains closed for a duration greater than or equal to the seventh preset time, it can be determined that the temperature inside the steam oven has reached the standard, and the fan speed will revert to the setting before the fan speed was increased.

[0137] Please see Figure 7 In an optional embodiment, before step S1, the method further includes:

[0138] S6. Obtain the initial weight of the food;

[0139] S601. Determine whether the initial weight is less than the fourth preset weight. If yes, proceed to step S602; otherwise, proceed to step S603.

[0140] S602. Set the wind speed setting to the seventh wind speed setting.

[0141] S603, Set the wind speed setting to the eighth wind speed setting;

[0142] Among them, the eighth wind speed setting is higher than the seventh wind speed setting.

[0143] In this embodiment, the heating rate of food can be determined by the fourth preset weight, thereby ensuring the taste of the food.

[0144] In this embodiment, determining the corresponding air speed gear according to the weight gear can be as Figure 8 shown.

[0145] For the standard for determining weight gears, a plurality of preset weights (such as B1, B2 and B3, where B1<B2<B3) can be set to determine the corresponding air speed gears. (The air speeds corresponding to the air speed gears are A, B and C, where A<B<C).

[0146] It should be noted that in this embodiment, although the air speed gears include the first air speed gear to the eighth air speed gear, the above-mentioned first air speed gear to the eighth air speed gear are provided for convenience of description, and are different names for the air speed gears, which do not necessarily mean that there are eight gear values, and they are not necessarily associated with gear values. It is only required that each air speed gear conforms to its own defined relative magnitude relationship.

[0147] In one embodiment, the steam-baking integrated appliance is provided with a temperature probe inside, which can detect the internal temperature condition. The temperature detected by the temperature probe is T0, and the temperature corrected to the center of the cavity is T1. The rotation speed of the fan has 6 gears, A1, A2, A3, A4, A5 and A6, where A1<A2<A3<A4<A5<A6>. The weight M of food is divided into 3 grades, B1, B2 and B3, where B1<B2<B3.

[0148] Before starting operation, the initial temperature of the cavity is recorded as T2. After food is placed in the cooking appliance, the initial weight M0 of the food is measured, and the operation is started immediately. When starting, the weight of food during the preheating process is recorded as M1. If M1<B1, the rotation speed of the fan is set to gear A2, otherwise the rotation speed of the fan is set to gear A3. At this time, the steam-baking appliance enters the preheating state. If the cavity center temperature T1<T2-D (D can be a preset value) within the preset time C1, the placed food is considered to be in a frozen state. Otherwise, the food is in a non-frozen state.

[0149] In the preheating state, if the food is in a frozen state:

[0150] When the food weight satisfies B1≤M1≤B2, the rotation speed of the fan is gear A4; when the food weight satisfies B2<M1≤B3, the rotation speed of the fan is gear A5; when the food weight satisfies M1>B3, the rotation speed of the fan is gear A6. When the cavity center temperature T1>E1 (E1 is a preset temperature value), the food changes from a frozen state to a non-frozen state.

[0151] When the food is in a frozen state, when M0≥B1 and M1<B1, if M1-M0>0.5M0, the fan speed gear is reduced to A2; if 0.25M0<M1-M0<0.5M0, the fan speed gear is reduced to A3; otherwise, the gear remains unchanged; when M1≥B1, the fan speed gear remains unchanged.

[0152] Preheating state, the food is in an unfrozen state:

[0153] When the food weight satisfies B1≤M1≤B2, the fan speed is set to gear A3; when the food weight satisfies B2<M1≤B3, the fan speed is set to gear A4; when the food weight satisfies M1>B3, the fan speed is set to gear A5.

[0154] During the preheating process, the weight of the food naturally decreases as the moisture in the food evaporates. However, for some dishes, it is necessary to brush sauce during the preparation process, which leads to an increase in the weight of the food.

[0155] If the food weight change N<0, when M1<B1 and M1-M0>0.5M0, the fan speed gear is reduced to A1; when M1<B1 and M1-M0≤0.5M0, or M1≥B1, the gear remains unchanged.

[0156] If the food weight change N>F1 (F1 is a preset value for weight change) and there is a door opening / closing action, the overall weight M1 of the food is inevitably greater than B1 at this time. In order to promote the sauce to quickly integrate into the food, timing starts from the moment when the cavity door is closed after brushing the sauce. When t1 is within the range of t1<C2, if the food weight satisfies B1≤M1≤B2, the fan speed is set to gear A4; if the food weight satisfies B2<M1≤B3, the fan speed is set to gear A5; if the food weight satisfies M1>B3, the fan speed is set to gear A6.

[0157] Heat preservation state:

[0158] When the central temperature T1 inside the cavity is greater than the set temperature T3, the cooking device switches from the preheating process to the heat preservation process, the duration of the heat preservation process is counted as t2, and the weight of the food during the heat preservation process is M2;

[0159] In heat preservation state, if the food is in a frozen state:

[0160] When the food is in a frozen state, when t2≤C3, the same fan speed gear as in preheating is maintained; when C3<t2<C4, if M2<B1, the fan speed gear is set to A2; when the food weight satisfies B1≤M2≤B2, the fan speed is set to gear A3; when the food weight satisfies B2<M2≤B3, the fan speed is set to gear A4; when the food weight satisfies M2>B3, the fan speed is set to gear A5; when t2≥C4, the food is switched from a frozen state to an unfrozen state.

[0161] In heat preservation state, if the food is in an unfrozen state:

[0162] Entering the heat preservation process, when the food is in a non-frozen state, when t2≤C3, the same wind speed gear as that in preheating is maintained; when t2>C3, if M2<B1, the fan rotation speed is set to gear A1; when the food weight satisfies B1≤M2≤B2, the fan rotation speed is set to gear A2; when the food weight satisfies B2<M2≤B3, the fan rotation speed is set to gear A3; when the food weight M2>B3, the fan rotation speed is set to gear A4.

[0163] When the temperature T3>E2 and t2≥C5 (C3<C4<C5), all ingredients are in a non-frozen state at this time. If the wind speed gear is below A3, it remains unchanged; otherwise, all wind speed gears are switched to gear A3 to prevent the surface of the food from being over-dried due to long-time heating.

[0164] During the entire cooking process, whether in the preheating process or the heat preservation process, if a door opening / closing action occurs, timing is performed for the total door opening duration as t3, and timing is performed for the time after door closing as t4. If there is no increase in the food weight: when t3<G1, the wind speed gear remains unchanged; when t3>G1, within the time period when t4<G2, the wind speed gears A1 and A2 remain unchanged, and other gears are automatically increased by one gear (if the gear is A6, it remains unchanged); when t4>G2, the gear is restored to the original gear. After the door is opened for a long time, increasing the rotation speed allows the internal heat to diffuse rapidly, which accelerates the temperature recovery speed inside the cooking appliance.

[0165] The above is only a specific example, wherein the number of wind speed gears, the weight grades, the values of the wind speed gears under various conditions and the specific values of each judgment condition are all provided for illustration only, and do not constitute a specific limitation on the protection scope of the present invention. Those skilled in the art can make adjustments according to actual needs.
