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 heating modes of existing steam ovens on the market include 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. There are often problems such as uneven heating of ingredients, uneven baking color, partial burning, and partial undercooking, resulting in poor cooking results. In addition, existing cooking equipment also has the problem of low intelligence.

[0003] Accordingly, the art needs a new cooking device and a control method thereof to solve the above problems. Summary of the invention

[0004] The invention aims to solve the above technical problem, that is, to solve the problem that the existing cooking equipment with hot air components has poor cooking effect and low intelligence.

[0005] 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, wherein the hot air component is suitable for supplying hot air into a cooking cavity of the cooking device, wherein the hot air component comprises a first hot air unit and a second hot air unit, wherein the first hot air unit is located at least at one side of the cooking cavity, and the second hot air unit is located at the top of the cooking cavity, and the second hot air unit comprises a second motor and a plurality of second fans, wherein the second motor is connected to the plurality of second fans, and the second motor can operate at a first speed or a second speed, wherein the first speed is greater than the second speed, and the control method comprises: acquiring feature information of ingredients to be cooked; determining a corresponding doneness judgment model based on the feature information; The method comprises the following steps: wherein the cooked food is cooked at least in a cooking chamber and the cooked food is cooked at least in a cooking chamber, wherein ...

[0006] In the control method provided by the present invention, a doneness judgment model with a mapping relationship (corresponding relationship) among multiple factors including at least characteristic information, doneness, and medium information is pre-established. During the cooking process, at least the medium information in the cooking cavity is obtained and compared with the selected doneness judgment model, so as to determine the doneness of the food to be cooked in the current cooking state, and control the first hot air unit and the second hot air unit to be turned off based on the doneness. In this way, the intelligence level of the cooking device can be improved. In addition, by setting a dual-speed motor, the second motor is operated at a first speed in the initial preheating stage, and at least one second fan is stopped after the second motor is operated at a second speed for a first preset time in the subsequent cooking stage. This is not only conducive to improving the preheating efficiency and achieving the purpose of rapid preheating, but also can avoid the problems of burning and excessive water loss of food by reducing the hot air circulation speed during the cooking process, which is conducive to keeping the food with a better taste.

[0007] It should be noted that the side of the cooking cavity includes one or more of a back side, a left side, and a right side.

[0008] It can be understood that the characteristic information of the ingredients to be cooked can include multiple different information. The doneness judgment model determined based on the characteristic information is a doneness curve that corresponds to each piece of information in the characteristic information. The relevant data in the specific doneness judgment model is obtained through experiments and pre-stored in the memory of the cooking equipment, and the data can be called when the program is executed.

[0009] Preferably, the present invention arranges hot air units on the top and back of the cooking device, and the two hot air units can be independently controlled and operated separately. In this way, when the two hot air units are turned on at the same time, all-round surrounding hot air can be formed around the food, making the surface color of the food more even.

[0010] In some feasible implementations of the control method of the above-mentioned cooking equipment, the doneness judgment model includes medium information and cooking time information that have a mapping relationship with the doneness of the food to be cooked, and the "at least obtaining the current medium information in the cooking cavity" includes: obtaining the current medium information and the current cooking time in the cooking cavity; the "at least determining the doneness of the food being cooked based on the comparison result of the current medium information and the doneness judgment model" includes: determining the doneness of the food being cooked based on the comparison result of the current medium information, the current cooking time and the doneness judgment model.

[0011] In the stage of establishing a doneness judgment model, in some cooking scenarios, such as in the process of baking biscuits, there are not only unripe zones and ripe zones, but often an overripe zone needs to be set up. It is necessary to continue cooking after it is fully cooked so that it enters the overripe zone, so as to improve the puffing and crispness of the biscuits. However, it is found in the experiment that when the doneness curve enters the overripe zone, the oxygen concentration in the cooking chamber will rebound, causing the doneness curve to show a trend of first decreasing and then increasing. As a result, it is easy to make an incorrect judgment when judging the oxygen concentration. In order to avoid this problem, the technical solution of the present invention can improve the accuracy of doneness judgment by introducing cooking time as one of the parameters for further judging doneness, which is conducive to obtaining better cooking results.

[0012] In some feasible implementations of the above-mentioned cooking device control method, the medium information includes at least one of oxygen concentration, oxygen concentration change rate, water loss rate, and humidity change rate.

[0013] The working principle of the technical solution of the present invention is as follows: during the cooking process of the food in the cooking chamber, the moisture in the food continues to dissipate, and the oxygen concentration in the cooking chamber gradually decreases. As the food gradually matures, the moisture loss rate will gradually decrease. When it is close to maturity, the moisture loss rate is extremely low, and the oxygen concentration basically no longer changes. When the food is in the mature zone, the oxygen concentration is the lowest. When the cooking stage of some food exceeds the mature zone and enters the over-mature zone, the oxygen concentration will rise. Based on this, by establishing a doneness judgment model that at least includes characteristic information, doneness, cutoff information such as oxygen concentration, cooking time, etc. in the experimental stage, the doneness in the current cooking scene can be determined by obtaining the oxygen concentration during the cooking process, or the accuracy of doneness judgment can be improved by obtaining the oxygen concentration and cooking time, thereby improving the cooking effect. Among them, the oxygen concentration can be obtained by the set oxygen concentration sensor.

[0014] Similarly, by obtaining the oxygen concentration in the cooking cavity at a set detection frequency, the oxygen concentration change rate can be obtained. In the experimental stage, by establishing the relationship between characteristic information, oxygen concentration change rate, doneness, etc., the doneness of the food can be known by obtaining the oxygen concentration change rate in the cooking cavity during the cooking process. The same is true for the moisture loss rate and humidity change rate. Among them, the moisture loss rate can be detected and calculated by inserting a humidity probe or a temperature and humidity probe into the food, and then obtained by the controller. The humidity change rate refers to the change rate of the humidity in the cooking cavity, which is detected by a humidity sensor set in the cooking cavity and further calculated. It can be understood that there is a corresponding relationship between the moisture loss rate of the food and the humidity change rate in the cooking cavity. Because the moisture lost from the food will enter the cooking cavity and affect the humidity in the cooking cavity, it is also possible to perform data correction by increasing the corresponding relationship between the two to obtain more accurate data results.

[0015] In some feasible implementations of the above-mentioned cooking device control method, the characteristic information at least includes category information.

[0016] In some feasible implementations of the above-mentioned cooking device control method, the characteristic information includes category information, and at least one of weight information, volume information, cooking layer number information, and shape information.

[0017] It is understandable that the type, weight, volume, number of cooking layers, etc. of the ingredients are most related to the changes in oxygen concentration and humidity in the cooking chamber, among which the type and weight of the ingredients have the greatest impact. For example, if the water content of the ingredients is different, the amount of water vapor entering the cooking chamber during the cooking process will be different, and the dilution effect on the oxygen concentration and the impact on the humidity will also be different.

[0018] Specifically, the category of ingredients can be obtained through voice, buttons, image analysis, etc., the weight of ingredients can be obtained through weight sensors, and the volume, number of cooking layers, etc. can be obtained through image analysis, etc.

[0019] In some feasible implementations of the control method of the cooking device described above, the second hot air unit further includes a transmission mechanism, and the second motor is connected to the plurality of second fans via the transmission mechanism.

[0020] By providing a transmission mechanism, it is not only helpful to shorten the size of the output shaft of the second motor, thereby improving its rigidity, but also conveniently realize the separate control of multiple second fans, thereby reducing the control cost.

[0021] In some feasible implementations of the above-mentioned cooking device control method, the transmission mechanism is a gear mechanism, and the output shaft of the second motor is retractable.

[0022] In this way, the same second motor can be used to conveniently drive a plurality of second fans and enable each second fan to operate independently without affecting other second fans.

[0023] In some feasible implementations of the control method of the cooking device described above, a heat dissipation duct is further provided above the cooking cavity, and the transmission mechanism is provided in the heat dissipation duct; or

[0024] The second hot air unit is configured with a second hot air cavity, and the transmission mechanism is disposed in the second hot air cavity.

[0025] 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.

[0026] 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.

[0027] 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

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

[0076] Combine the following Figures 1 to 6 The structure of the steam oven provided in the embodiment of the present invention is described.

[0077] like Figure 1 As shown in , the steam oven provided by 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.

[0078] 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.

[0079] 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 liner assembly 2 , and the second hot air unit 23 is located at the top of the inner liner assembly 2 .

[0080] It can be understood that the first hot air unit 22 can be further arranged on the left side and / or the right side of the cooking cavity, or only arranged on the left side and / or the right side.

[0081] like Figures 1 to 4 As shown in , the first hot air unit 22 includes a first fan cover 221, a first electric heater 222, a first fan 223, etc. Specifically, as Figure 2 and Figure 4 As shown, the first fan cover 221 is connected to the inner side of the inner liner back plate 211, and together with the inner liner back plate 211, a first hot air cavity 227 is constructed, and the first electric heater 222 and the first fan 223 are placed in the first hot air cavity 227. Figure 1 and Figure 2 As shown in the figure, a plurality of ventilation holes are arranged on the first fan cover 221, the ventilation holes located in the middle constitute the air inlet 2211 of the first hot air cavity 227, and 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 on the periphery of the air inlet 2211 constitute the air outlet 2212 of the first hot air cavity 227, and 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.

[0082] like Figure 1 As shown in , the first electric heater 222 is wound into a ring structure, so that it can be arranged around the periphery of the first fan 223, which is not only beneficial to improving the heating efficiency, but also beneficial to saving installation space.

[0083] like Figure 1 and Figure 4 As shown in , 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 tank 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 cooling fan 225, and the first cooling fan 225 rotates synchronously with the first fan 223, so that the first motor 226 drives the first cooling 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. Figure 4 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 .

[0084] The second hot air unit 23 in the embodiment of the present invention includes a second fan cover 231, a second electric heater 232, a second fan 233, a second cooling fan 234, a second motor 235, a transmission mechanism 237 and the like.

[0085] Specifically, Figure 1 , Figure 4 and Figure 5 As shown in FIG. 2 , 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 forms a second hot air chamber 236, in which the second electric heater 232, the second fan 233 and the transmission mechanism 237 are placed. Figure 5As shown in , the second fan cover 231 is provided with a plurality of ventilation holes, which are arranged in a circular array and correspond to the two second fans 233. Part of the ventilation holes near the center of the array constitute an air inlet 2311, and the air in the cooking cavity can enter the second hot air cavity 236 through the ventilation holes of the air inlet 2311, and the ventilation holes located at the periphery of the air inlet 2311 and away from the center of the array constitute an air outlet 2312, and the hot air in the second hot air cavity 236 can enter the cooking cavity through the air outlet 2312, so that the hot air circulates between the second hot air cavity 236 and the cooking cavity.

[0086] Alternatively, a plurality of ventilation holes may be provided at the position near the edge of the second fan cover 231 to construct the air outlet of the second hot air chamber. In addition, the transmission mechanism 237 may also be provided in the heat dissipation air duct 33 .

[0087] like Figure 1 , Figure 4 and Figure 6 As shown, in this embodiment, two second fans 233 are provided, and the two second fans 233 are arranged at intervals along the length direction of the inner tank body 21. Figure 4 As shown in , in this embodiment, a transmission mechanism 237 is also provided, and the transmission mechanism 237 is arranged in the second hot air chamber 236. The transmission mechanism 237 includes three gears meshing with each other, wherein the gear located in the middle is connected to the output shaft 2351 of the second motor 235, and the gears located on both sides of the middle gear are respectively connected to the corresponding second fans 233. Driven by the second motor, the two second fans 233 can be rotated synchronously or asynchronously, and the asynchronous rotation can be achieved by adjusting the parameters of each gear. Further, the output shaft 2351 of the second motor 235 in the embodiment of the present invention can drive the intermediate gear to make telescopic movement along its axial direction, and the driven gears located on both sides have a height difference in the height direction. The telescopic output shaft 2351 can drive the driving gear to move in the vertical direction relative to the driven gear, so that the second motor 235 can only drive one of the second fans 233 to rotate and stop the other second fan from running. This setting can play an important role in the subsequent operation mode adjustment or parameter adjustment process.

[0088] In this embodiment, the second motor 235 is a dual-speed motor, which can run at a first speed or a second speed, thereby driving the second fan 233 to run at a first speed or a second speed, wherein the first speed is greater than the second speed.

[0089] In addition, the output shaft 2351 of the second motor 235 can be retracted, thereby driving the intermediate gear in the transmission mechanism 237 connected thereto to move up and down relative to the driven gear, so that the second motor 235 can switch between three working states: driving two second fans to rotate at the same time, driving only the left second fan to rotate, and driving only the right second fan to rotate.

[0090] Alternatively, the transmission mechanism 237 may also be a pulley mechanism; in addition, two second motors may also be provided, each second motor being used to drive a second fan, so as to achieve the purpose of independently controlling the two second fans. It is understandable that the second fans may also be any suitable number such as 3 or 4. In addition, the plurality of second fans may also be arranged at intervals along the width direction of the liner body 21, or arranged at intervals along the diagonal direction, or arranged in an array structure, etc.

[0091] like Figure 1 , Figure 3 and Figure 4 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 air circulation in the heat dissipation air duct 33. The heat dissipation fan 32 is a cross-flow fan. Figure 4 As shown in the figure, in this embodiment, the top surface of the air duct cover plate 31 is tilted relative to the inner top plate 13 to form a heat dissipation air duct 33 with a tapered cross section, and the second motor is connected to the outer top surface of the air duct cover plate 31 through a second motor bracket (not shown). During the installation process, the output 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 transmission mechanism 237 located in the second hot air chamber 236, and the transmission mechanism 237 is connected to the two second fans 233 respectively.

[0092] To prevent the motor from overheating during operation, the second motor 235 is also connected to a second cooling fan 234. The second cooling fan 234 rotates synchronously with the second fan 233 and is connected to the output shaft 2351. The second motor 235 drives the second cooling fan 234 to rotate while driving the second fan 233, thereby promoting the heat dissipation of the second motor 235 itself.

[0093] like Figure 6 As shown in , the second electric heater 232 is arranged on the periphery of the second fan 233. In this embodiment, the second electric heater 232 includes two heating tubes, and the two heating tubes can be independently controlled to open and close to facilitate the adjustment of the power of the second electric heater 232.

[0094] In addition, since the embodiment of the present invention is described by taking a steam oven as an example, the steam oven is also provided with a steam supply system (not shown), including an evaporating plate arranged on the bottom plate of the inner pot (not marked), an evaporating plate heating tube 25 located below the evaporating plate, and the like.

[0095] It can be understood that when the steaming function is not configured, the relevant structure for generating steam is not necessary.

[0096] Based on the above steam oven structure, the embodiment of the present invention also provides a control method, such as Figure 7 As shown in, the control method provided by the embodiment of the present invention includes:

[0098] Specifically, in this embodiment, the characteristic information includes category information and weight information. The category information is obtained by an image acquisition device, or a button or touch screen is set on the control panel and selected manually by the user. The weight information is obtained by setting a weight sensor connected to the tray.

[0099] S20. Determine a corresponding doneness judgment model based on the feature information, wherein the doneness judgment model includes medium information and cooking time information that have a mapping relationship with the doneness of the food to be cooked.

[0100] Specifically, the doneness judgment model includes several doneness curves, each of which is a correspondence between doneness and medium information established on the premise of setting characteristic information. In this embodiment, since the characteristic information includes category information and weight information, the doneness judgment model establishes several relationship curves between doneness and medium information based on different categories and weights. When the steam oven automatically obtains the category and weight of the food to be cooked, it can select a doneness curve that is suitable for the current scene from the several curves in the doneness judgment model, and the doneness of the food can be further judged based on the curve.

[0101] For example, Figure 8 As shown in Figure 8The corresponding doneness curves of biscuits in the cases of 500g (corresponding to small portion) and 1000g (corresponding to large portion) are shown in the figure, where the medium information is oxygen concentration. As can be seen from the figure, as the cooking time continues, the oxygen concentration in the cooking chamber shows a trend of first decreasing and then slightly increasing. The study found that during the period when the oxygen concentration shows a decreasing trend, the food is in the immature zone. When the oxygen concentration remains basically unchanged, it indicates that the food has been cooked to maturity. For some food ingredients, the food ingredients can be taken out after they are mature, but in some cases or for specific food ingredients, such as cooking biscuits, they will continue to be cooked to a certain extent after maturity to make them enter the over-mature zone, so that they can be expanded better and maintain a better shape. As can be seen from the figure, for food ingredients or foods that enter the over-mature zone, the oxygen concentration will rise to a certain extent.

[0102] like Fig. 9 As shown in Fig. 9 The figure shows the doneness curves of meat in the case of 500g (corresponding to a small portion) and 1000g (corresponding to a large portion), where the medium information is the oxygen concentration. It can be seen from the figure that as the cooking time continues, the oxygen concentration in the cooking chamber shows a trend of first decreasing and then slightly increasing.

[0103] like Fig.10 As shown in Fig.10 The figure shows the corresponding doneness curves of bread in the case of 500g (corresponding to a small portion) and 1000g (corresponding to a large portion), where the medium information is the oxygen concentration. It can be seen from the figure that as the cooking time continues, the oxygen concentration gradually stabilizes and no longer changes.

[0104] It should be noted that “determining a corresponding doneness judgment model” here refers to determining a corresponding doneness curve.

[0105] S30, operating the first hot air unit and the second hot air unit at full power until a preset temperature is reached, and then switching the second motor to operate at a second speed.

[0106] Specifically, after determining the doneness curve, first operate the first hot air unit and the second hot air unit at full power. Full power operation here means that under the premise of ensuring operational safety, both the electric heater and the fan are operated at maximum power (speed) to rapidly increase the temperature in the cooking cavity until it reaches a preset temperature. The preset temperature is automatically determined based on the acquired characteristic information. For example, in the case of barbecue, the preset temperature may be 200°C, and in the case of roasting vegetables, the preset temperature may be 150°C, and so on.

[0107] When the preset temperature is reached in the cooking cavity, the second motor is switched from the first speed to the second speed, for example, if the first speed is 1500 rpm, it is switched to 1000 rpm.

[0108] S40: After the second motor is operated at the second speed for a first preset time period, at least one of the plurality of second fans is stopped.

[0109] Specifically, by controlling the extension and retraction of the output shaft of the second motor to change the matching relationship between the gears in the gear mechanism, one of the two second fans stops running, so as to further slow down the hot air circulation speed in the cooking chamber. In this way, by sequentially adjusting the speed of the second motor and the number of running second fans, a cooking effect of high-fire preheating-medium-fire cooking-low-fire slow baking is achieved, so that the food tastes better.

[0110] S50: While the hot air component is running, obtain current medium information and current cooking time in the cooking cavity.

[0111] Specifically, in this embodiment, the current medium information, i.e., the current oxygen concentration in the cooking cavity, is obtained by an oxygen concentration sensor disposed on the top of the cooking cavity. In addition, the detection of the oxygen concentration can be started after preheating is completed, or after preheating is completed and cooking continues for a period of time.

[0112] S60: Determine the doneness of the food being cooked based on the comparison result of the current medium information, the current cooking time and the doneness judgment model.

[0113] Specifically, the oxygen concentration is calculated based on the measured oxygen concentration, and the doneness of the food currently being cooked can be obtained based on the current oxygen concentration and the doneness judgment model, thereby achieving automatic acquisition of doneness results.

[0114] Specifically, Figure 8 As shown in the figure, the oxygen concentration reaches 18.9 mg / m 3 When the oxygen concentration is 0.5, it indicates that the biscuits are fully cooked. The cooking time corresponding to this oxygen concentration is 18 minutes. After obtaining the cooking time and oxygen concentration, the maturity of the ingredients can be accurately judged. The same is true for large biscuits.

[0115] like Fig. 9 As shown in the figure, when a small portion of meat is cooked in an oxygen concentration of 16.5 mg / m 3 , When the cooking time reaches 40 minutes, the meat reaches 100% doneness. The same applies to large portions of meat.

[0116] like Fig.10 As shown in Figure 2, when the cooking time of a small portion of bread reaches 20 minutes and the oxygen concentration reaches 17.6 mg / m 3 When it reaches 100% maturity, the same applies to large loaves of bread.

[0117] S70. When the degree of doneness reaches a preset degree of doneness, control the first hot air unit and the second hot air unit to stop operating.

[0118] Specifically, when it is determined that 100% maturity has been achieved, the first hot air unit and the second hot air unit are controlled to be turned off.
