Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and specifically provides a cooking equipment and a control method thereof, a computer device, a storage medium, and an integrated stove. Background Art

[0002] Cooking equipment such as ovens and steam ovens are essential kitchen appliances for modern families. Taking steam ovens as an example, the existing steam ovens on the market have heating modes such as upper heating tubes, bottom heating tubes, and back heating tubes. Different heating modes are achieved by running different heating tube combinations. Since the heating tubes are fixedly installed, the shape of the heating tubes cannot be too complicated due to the processing technology, and there are often problems such as uneven heating of ingredients, uneven baking color, partial burnt, and partial undercooked.

[0003] In order to heat the ingredients in the oven cavity evenly and bake them with uniform color, some ovens have added a hot air device on the back that can promote the circulation of hot air. The operation of the motor and fan in the hot air device promotes the circulation of hot air in the cooking cavity, which is beneficial to keep the color of the ingredients even. However, the hot air device can also bring some problems. Compared with traditional heat radiation ovens, hot air circulation can more easily take away moisture and fat on the surface of the ingredients, which can easily make the cooked food dry and hard, affecting the taste.

[0004] Accordingly, the art needs a new cooking device to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing cooking equipment with hot air components easily causes the food to have a poor taste.

[0006] In a first aspect, the present invention provides a control method for a cooking device, wherein the cooking device is provided with a hot air component, and the hot air component is suitable for supplying hot air into a cooking cavity of the cooking device, the hot air component includes a first hot air unit and a second hot air unit, the first hot air unit is located at least on one side of the cooking device and includes a first electric heater, and the second hot air unit is located on the top of the cooking device and includes a second electric heater, and the control method includes: acquiring characteristic information of food to be cooked; selecting a working mode of the hot air component and determining an oil fume concentration threshold based on the characteristic information; during the operation of the hot air component, detecting the oil fume concentration in the cooking cavity, the oil fume concentration threshold and the characteristic information having a preset mapping relationship; comparing the oil fume concentration with the oil fume concentration threshold; if the oil fume concentration is greater than the oil fume concentration threshold, adjusting the working mode of the hot air component and / or adjusting the working parameters of the hot air component, wherein before detecting the oil fume concentration in the cooking cavity, the first hot air unit and the second hot air unit are turned on at full power until the working temperature corresponding to the selected working mode is reached.

[0007] In the control method of the cooking device provided by the present invention, by adding the detection of oil fume concentration when the hot air component is running, the cooking device can judge the degree of loss of moisture, fat, etc. of the ingredients being cooked based on the change of oil fume concentration, and accordingly the operation mode and / or working parameters of the hot air component can be adjusted in time, so as to ensure that the taste of the food is in a better state and avoid the problem of taste degradation due to excessive loss of moisture, fat, etc. In addition, by turning on the first hot air unit and the second hot air unit at full power before formal cooking, the temperature in the cooking cavity can quickly reach the working temperature, thereby improving the preheating efficiency.

[0008] Specifically, by establishing a mapping relationship between the characteristic information of various ingredients to be cooked and the oil fume concentration threshold in advance, in the actual working process, it is only necessary to accurately determine the oil fume concentration threshold corresponding to the current ingredient to be cooked through information matching. The oil fume concentration threshold is related to the degree of loss of important components of the corresponding ingredients, including nutrients such as moisture, fat, protein, etc. that affect the taste.

[0009] The specific principle is: the principle of oil fume generation during cooking is mainly because the fat and other ingredients in the food decompose and volatilize at high temperature to produce volatile compounds to form a mixed gas in the air. The whole process is a gas phase reaction. Therefore, by detecting the concentration of the generated oil fume, the loss of moisture and fat in the food can be judged. Since the moisture and fat of the food are important factors affecting the taste, the concentration of oil fume can indirectly reflect the retained moisture, fat, etc., and then it can be judged whether the cooked food maintains a better taste.

[0010] In addition, it should be noted that turning on the first hot air unit and the second hot air unit at full power means turning on the first electric heater and the second electric heater at full power.

[0011] It is understandable that one side of the cooking device may be its back, or its left side or right side.

[0012] In some feasible embodiments of the above-mentioned cooking device, the working mode includes operating only the first hot air unit, operating only the second hot air unit, operating the first hot air unit and the second hot air unit at the same time, and operating the first hot air unit and the second hot air unit alternately.

[0013] The first hot air unit is constructed with a first hot air cavity, the first electric heater is placed in the first hot air cavity, the second hot air unit is constructed with a second hot air cavity, the second electric heater is placed in the second hot air cavity, and the operating parameters include the power and / or duty cycle of the first electric heater, and / or the power and / or duty cycle of the second electric heater.

[0014] In some feasible implementations of the above cooking device, a first fan is further provided in the first hot air chamber, and the operating parameters further include the operating time and / or speed of the first fan; and / or

[0015] A second fan is also provided in the second hot air chamber, and the operating parameters further include the operating time and / or rotation speed of the second fan.

[0016] In some feasible implementations of the above cooking device, the characteristic information at least includes category information.

[0017] It is understandable that the type of food is most relevant to the generation of oil fume. Foods that are full of fat and water, such as beef and mutton, are more likely to produce oil fume during the cooking process, while pasta with a higher sugar content is not easy to produce oil fume. Determining different oil fume concentration thresholds for different food ingredients can make cooking more targeted, thus facilitating better cooking results.

[0018] In some feasible implementations of the above cooking device, the characteristic information includes category information, and at least one of weight information, volume information, and smoke-generating surface area information.

[0019] By further combining at least one of the weight information, the volume information, and the smoke surface area information to determine the oil fume concentration threshold, the oil fume concentration threshold can be more closely matched with the current cooking scene, thereby obtaining a better cooking effect.

[0020] In some feasible implementations of the above cooking device, the oil fume concentration is measured by an oil fume sensor disposed at or near the top of the cooking cavity.

[0021] In a second aspect, the present invention further provides a computer device comprising a memory and a processor, wherein the memory is suitable for storing a plurality of program codes, and the program codes are suitable for being loaded and run by the processor to execute the control method of the cooking device described in any of the aforementioned technical solutions.

[0022] In a third aspect, the present invention further provides a computer-readable storage medium storing a plurality of program codes, wherein the program codes are suitable for being loaded and run by a processor to execute the control method of the cooking device described in any of the aforementioned technical solutions.

[0023] In a fourth aspect, the present invention further provides a cooking device, the cooking device comprising the computer device described in the above technical solution; or

[0024] The cooking device includes the computer-readable storage medium described in any of the aforementioned technical solutions.

[0025] In a fifth aspect, the present invention further provides an integrated stove, which includes the cooking device described in the aforementioned technical solution.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0063] Combine the following Figures 1 to 5 The structure of the all-in-one machine provided by the embodiment of the present invention is described.

[0064] like Figure 1 As shown in , the all-in-one machine provided in the embodiment of the present invention includes a box body and a door body (not shown), and the door body is pivotally connected to the box body. The box body includes an outer shell 1 and an inner tank assembly 2, a heat dissipation assembly 3, etc. arranged in the outer shell 1. The outer shell 1 is composed of an outer plate 11, an outer bottom plate 12, an inner top plate 13, an outer top plate (not shown), an outer back plate 14, a front panel 15, etc., wherein the outer plate 11, the outer bottom plate 12, the inner top plate 13 and the outer back plate 14 are assembled to construct an installation cavity for accommodating the inner tank assembly 2, and the inner tank assembly 2 is installed in the installation cavity, the heat dissipation assembly 3 is installed above the inner top plate 13, and a knob 151 is provided on the front panel 15.

[0065] The inner tank assembly 2 in the embodiment of the present invention includes an inner tank body 21 and a hot air assembly connected to the inner tank body 21 , a hanger 24 , an evaporation plate heating tube 25 , and the like.

[0066] like Figures 1 to 3 As shown, the hot air assembly in this embodiment includes a first hot air unit 22 and a second hot air unit 23. The first hot air unit 22 is located at the back of the inner tank assembly 2, and the second hot air unit 23 is located at the top of the inner tank assembly 2. The first hot air unit 22 includes a first fan cover 221, a first electric heater 222, a first fan 223, etc. The first fan cover 221 is connected to the inner side of the inner tank back plate 211, and together with the inner tank back plate 211, a first hot air cavity 227 is constructed. The first electric heater 222 and the first fan 223 are placed in the first hot air cavity 227. Figure 3As shown in the figure, the first fan cover 221 is provided with a plurality of ventilation holes, the ventilation holes located in the middle constitute the air inlet 2211 of the first hot air cavity 227, the air in the cooking cavity can enter the first hot air cavity 227 through the ventilation holes of the air inlet 2211, and the ventilation holes located at the periphery of the air inlet 2211 constitute the air outlet 2212 of the first hot air cavity 227, the hot air in the first hot air cavity 227 can enter the cooking cavity through the air outlet 2212, so that the hot air circulates between the first hot air cavity 227 and the cooking cavity. The first fan 223 is connected to the first motor 226, and the first motor 226 is fixedly connected to the outer side of the inner pot back plate 211 through the first motor bracket 224. In order to prevent the motor from overheating during operation, the first motor 226 is also connected to the first heat dissipation fan 225, and the first heat dissipation fan 225 rotates synchronously with the first fan 223, so that the first motor 226 drives the first heat dissipation fan 225 to rotate during the period of driving the first fan 223 to operate, thereby promoting the heat dissipation of the first motor 226 itself. like Figure 2 As shown in , in the installed state, the first motor 226 , the first cooling fan 225 and the first motor bracket 224 are located in the space between the inner tank back plate 211 and the outer back plate 14 .

[0067] It is understandable that the first hot air unit can also be arranged on the left and right sides of the inner tank body or one of the two sides, or can also be arranged on the back of the inner tank body and the left and right sides or one of the two sides.

[0068] Continue to refer to Figures 1 to 3 In the embodiment of the present invention, the second hot air unit 23 includes a second fan cover 231, a second electric heater 232, a second fan 233, a second cooling fan 234, a second motor 235, etc. Specifically, the second fan cover 231 is connected to the inner side of the inner liner top plate 212, and together with the inner liner top plate 212, a second hot air cavity 236 is constructed, and the second electric heater 232 and the second fan 233 are placed in the second hot air cavity 236. Figure 1As shown in , a plurality of ventilation holes are arranged in a circular array in the middle of the second fan cover 231, wherein some ventilation holes near the center of the array constitute the air inlet of the second hot air chamber 236, and the air in the cooking chamber can enter the second hot air chamber 236 through the ventilation holes of the air inlet, and the ventilation holes located at the periphery of the air inlet and away from the center of the array constitute the air outlet of the second hot air chamber 236, and the hot air in the second hot air chamber 236 can enter the cooking chamber through the air outlet, so that the hot air circulates between the second hot air chamber 236 and the cooking chamber. The second fan 233 is connected to the second motor 235. In order to prevent the motor from overheating during operation, the second motor 235 is also connected to the second heat dissipation fan 234, and the second heat dissipation fan 234 rotates synchronously with the second fan 233, so that the second motor 235 drives the second heat dissipation fan 234 to rotate during the operation of the second fan 233, thereby promoting the heat dissipation of the second motor 235 itself. When installed, the shaft 2351 of the second motor 235 passes through the heat dissipation assembly 3 and is connected to the second fan 233.

[0069] like Figure 2 As shown in , the heat dissipation assembly 3 includes an air duct cover plate 31 and a heat dissipation fan 32. The air duct cover plate 31 is connected to the inner top plate 13 to form a heat dissipation air duct 33. The heat dissipation fan 32 is connected to the heat dissipation air duct 33 to promote the circulation of air in the heat dissipation air duct 33. The heat dissipation fan 32 is a cross-flow fan. When the installation is completed, the shaft of the second motor 235 passes through the air duct cover plate 31, the inner top plate 13 and the inner tank top plate 212 in sequence and is connected to the second fan 233 located in the second hot air chamber 236. Figure 3 As shown in , a pressure relief port 2121 is also formed on the inner pot top plate 212, and the pressure relief port 2121 is selectively opened when the steaming mode is running to adjust the pressure in the cooking cavity.

[0070] It should be noted that the connection method between the second motor 235 and the second fan 233 in the above embodiment is merely exemplary. For example, the second motor 235 can also be connected to the second fan 233 through a transmission mechanism. In addition, in addition to being placed above the air duct cover 31, the second motor 235 can also be placed in the heat dissipation duct 33, etc. These adaptive changes should be limited within the scope of protection of the present invention.

[0071] In addition, since the embodiment of the present invention is described by taking the steaming, baking and frying machine as an example, the all-in-one machine is also provided with a steam supply system (not shown), including a steam generator, a steam delivery pipe, etc., as well as an evaporating plate arranged on the bottom plate of the inner pot (not marked), an evaporating plate heating tube 25 located under the evaporating plate, etc.

[0072] It is understandable that when the steaming function is not configured, the above structures are not necessary.

[0073] In addition, if Figure 1 As shown in the figure, the all-in-one machine in the embodiment of the present invention is also provided with an oil fume sensor 4 near the top of the cooking cavity. The detection end of the oil fume sensor 4 extends deep into the cooking cavity or the second hot air cavity 236 to detect the oil fume concentration during the cooking process.

[0074] Based on the above-mentioned integrated machine structure, the present invention provides a control method based on the structure.

[0075] In order to improve cooking efficiency and reduce preheating time, this embodiment provides a control method, which uses two hot air units to perform rapid preheating before formal cooking.

[0076] Specifically, Figure 6 As shown, the control method provided in this embodiment includes:

[0077] S101, obtaining characteristic information of ingredients to be cooked.

[0078] Specifically, the characteristic information of the food to be cooked is obtained after the user places the food to be cooked in the cooking cavity and closes the door. The characteristic information can be obtained by an automatic recognition device such as an image recognition device, or by interaction with the user, such as the user directly inputting the characteristic information of the food to be cooked into the all-in-one machine through voice, physical or virtual buttons on the control panel, etc.

[0079] In this embodiment, the characteristic information of the ingredients to be cooked includes the category information and weight information of the ingredients to be cooked, wherein the category of the ingredients is obtained by manual input by the user, and the weight information of the ingredients is obtained by a weight sensor arranged on the inner pot body. The category and weight of the ingredients are the two characteristics most relevant to the smoking process.

[0080] Specifically, this embodiment takes barbecued meat skewers and barbecued chicken wings as examples, each weighing 500 g. After the meat skewers and chicken wings are placed in the cooking cavity, two feature information, namely, category and weight, can be obtained.

[0081] S102: Selecting a working mode of the hot air component and determining a smoke concentration threshold based on the characteristic information.

[0082] The working modes of the hot air component in this embodiment include operating only the first hot air unit, operating only the second hot air unit, operating the second hot air unit and the first hot air unit at the same time, and operating the first hot air unit and the second hot air unit alternately.

[0083] In addition, the process of selecting the working mode of the hot air component based on the characteristic information can be automatic or user-assisted. For example, when the type of food to be cooked is meat and the weight is large, it can be automatically selected to run the first hot air unit and the second hot air unit at the same time. When the weight of the food to be cooked is small, it can be automatically selected to run only the first hot air unit or the second hot air unit, and so on.

[0084] In addition, the process of determining the oil fume concentration threshold based on characteristic information is an information matching process. In the experimental stage, several experiments are conducted on different food categories and weight combinations to obtain the oil fume concentration threshold corresponding to the food category and weight combination under the best taste state and store the obtained data. When in use, the most matching oil fume concentration threshold can be directly obtained based on the results of obtaining the category information and weight information. That is, the characteristic information and the oil fume concentration threshold have a preset mapping relationship, and the oil fume concentration threshold is associated with the degree of loss of important components of the corresponding food, including water, fat and other substances that are easy to form oil fume and affect the taste.

[0085] Alternatively, in order to determine the oil fume concentration threshold more accurately, in the stage of obtaining the oil fume concentration threshold data through experiments, it is possible to further increase the association with characteristic information such as food volume and smoke-generating surface area.

[0086] Specifically, since there is a corresponding relationship between the characteristic information, the working mode and the oil fume concentration threshold, the working mode and the corresponding oil fume concentration threshold can be determined through the characteristic information. It should be noted that the working mode can also be manually selected by the user. In this embodiment, the oil fume concentration threshold for barbecued meat skewers is set to 70mg / m 3 The smoke concentration threshold for grilled chicken wings is set at 60 mg / m 3 It is understandable that, taking barbecued meat as an example, the fume concentration threshold can also be set to 80 mg / m 3 , 90mg / m 3 and other appropriate values. The larger the oil fume concentration threshold, the deeper the grilling degree. Different oil fume concentration thresholds correspond to different grilling degrees and tastes. The specific threshold is determined by feature information and a preset corresponding relationship.

[0087] S103, turning on the first hot air unit and the second hot air unit at full power until the operating temperature corresponding to the selected operating mode is reached.

[0088] It should be noted that the full-power startup here means that the first electric heater and the second electric heater are turned on at full power. For the first fan and the second fan, they can be turned on at the default speed or the lowest speed, or they can be turned on after the first electric heater and the second electric heater are turned on for a set time to increase the temperature. The purpose is to slowly disturb the air flow to make the temperature uniform everywhere.

[0089] Specifically, if the stable operating temperature of the selected working mode is 200°C, and the working mode is to run only the first hot air unit, the first hot air unit and the second hot air unit are turned on at full power until they reach 200°C, and then the second hot air unit is controlled to be turned off and the first hot air unit continues to run; if the stable operating temperature of the selected working mode is 200°C, and the working mode is to run the first hot air unit and the second hot air unit at the same time, the first hot air unit and the second hot air unit are turned on at full power until they reach 200°C, and then the working parameters of the first hot air unit and the second hot air unit are controlled to be converted to the default working parameters, such as lowering the electric heating power and increasing the fan speed as needed.

[0090] For example, in the preheating stage, the first hot air unit is started at a power of 1000W, and the second hot air unit is started at a power of 2000W, and the duty cycle at this time is 1. After reaching 200°C, the first hot air unit and the second hot air unit are adjusted to operate in a situation corresponding to the working parameters of the selected working mode, such as the selected working mode is to run the first hot air unit and the second hot air unit at the same time, and the duty cycle of the first hot air unit and the second hot air unit is 0.9. During operation, the speed of the first motor and the second motor is constant, and the speed is not adjusted during the cooking process. The adjustment working parameters in this embodiment only adjust the power of the electric heating.

[0091] S104: While the hot air component is running, detect the oil smoke concentration in the cooking cavity.

[0092] Specifically, the oil fume concentration is measured by an oil fume sensor disposed on the top of the cooking cavity.

[0093] S105: Compare the oil fume concentration with an oil fume concentration threshold.

[0094] S106: Control the action of the hot air component based on the comparison result.

[0095] Specifically, there are two comparison results: the oil fume concentration is greater than the oil fume concentration threshold and the oil fume concentration is less than the oil fume concentration threshold.

[0096] S1061. If the oil fume concentration is greater than (or greater than or equal to) the oil fume concentration threshold, adjust the working mode of the hot air component and / or adjust the working parameters of the hot air component.

[0097] When the oil fume concentration is greater than (or greater than or equal to) the oil fume concentration threshold, it indicates that the loss of fat and moisture on the surface of the food has reached a certain level. To ensure that the food has a fresh and tender taste, the generation of oil fume is reduced by adjusting the working mode of the hot air component and adjusting the working parameters of the hot air component, thereby reducing the loss of moisture, fat and other components.

[0098] Specifically, if the working mode needs to be adjusted, such as the pre-selected working mode is to run the first hot air unit and the second hot air unit at the same time, the adjusted working mode can be to run only the first hot air unit or only the second hot air unit, that is, to shut down one of the hot air units, reduce the circulation of hot air, and thus slow down the subsequent loss rate of components such as water and fat.

[0099] In addition, the above purpose can also be achieved by adjusting the working parameters of the hot air component. Specifically, the working parameters include at least one of the power of electric heating, the duty cycle of electric heating, the operating time of electric heating and / or fan, and the speed of the fan. Among them, the power and duty cycle of electric heating are used to adjust the cooking temperature, and the speed of the fan is used to regulate the circulation strength of the hot air. In addition, due to changes in temperature or wind speed, the cooking time (corresponding to the operating time of electric heating and the operating time of the fan) can be further adjusted to ensure that the food reaches the predetermined degree of doneness.

[0100] For example, when grilling skewers, if the smoke concentration threshold is detected to be above 70 mg / m 3 , by adjusting the duty ratio of the first electric heating and the second electric heating, such as adjusting the duty ratio of the first electric heating to 0.8 and the duty ratio of the second electric heating to 0.8, the output heat is reduced to ensure the taste of the food. When the cooking time reaches the preset cooking time, the first hot air unit and the second hot air unit are controlled to stop. It is understandable that in order to improve food safety, a safety threshold of oil fume concentration can also be set, such as 100mg / m 3 When the oil smoke concentration is detected to exceed 100mg / m 3 , the first hot air unit and the second hot air unit are promptly controlled to stop running without considering the cooking time to avoid damaging the food.

[0101] Similarly, when grilling chicken wings, if the smoke concentration threshold exceeds 60mg / m 3 By adjusting the duty ratio of the first electric heating and the second electric heating, such as adjusting the duty ratio of the first electric heating to 0.8 and the duty ratio of the second electric heating to 0.8, the output heat can be reduced to ensure the taste of the food.

[0102] It should be noted that the numerical values ​​involved in the above examples are merely exemplary and should not be construed as limiting the scope of protection of the present invention.

[0103] It is understandable that the working mode can also be adjusted by adjusting only the second hot air unit when only the first hot air unit is running, or adjusting only the first hot air unit when only the second hot air unit is running. In addition, the working mode can be adjusted directly without adjusting the working mode, and the working parameters of each hot air unit or a hot air unit can be adjusted directly.

[0104] S1062: If the oil fume concentration is less than or equal to (or less than) the oil fume concentration threshold, the cooking process is performed normally until the preset cooking time is reached.
