Description

Technical Field

[0001] The present invention relates to the technical field of ovens, and more particularly to an oven electric heating intelligent control system and a control method thereof, and an oven. Background Art

[0002] An oven is a sealed container used for baking or drying food. It is popular because of its fast heating and good baking effect. It is used to make roast chicken, roast duck, baked bread, pastries and other foods.

[0003] The existing oven includes an oven body, a baking area, a heating part, a rotating assembly, and a lifting assembly. The oven body also includes: a detection unit, which detects the baking progress of food on the first baking tray and the second baking tray and generates baking detection information; a processing unit, which divides the baked food into several areas and evaluates the baking progress based on the baking detection information. If baking is not completed, evaluation information is generated, and a control strategy is formed based on the evaluation information; a control unit, which receives the control strategy, generates corresponding control instructions, and controls the rotating assembly, the lifting assembly, and the temperature control module respectively; adjusts the position of food passing through the baking area to obtain the optimal regional temperature baking; because the steam in the oven chamber floats on the top of the chamber, the temperature at the top and bottom ends of the chamber is higher than the temperature in the middle layer, and the position of the baked food needs to be adjusted by the cooperation of the rotating assembly and the lifting assembly to ensure that the surface of the food is evenly heated. However, the linkage between the two requires electricity supply, which is complicated and increases energy consumption, thereby increasing the purchase and use cost of the oven;

[0004] In addition, heating needs to be stopped immediately after baking, and the baked food needs to be quickly removed from the oven cavity. On the one hand, this is to prevent the food from being burnt, and on the other hand, it is to prevent the condensed steam from dripping onto the surface of the food and affecting the taste of the food. However, when quickly opening the box, the high-temperature steam in the oven cavity can easily burn the user's skin.

[0005] Therefore, a new electric heating intelligent control system for an oven and a control method thereof, and an oven are badly needed. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides an oven electric heating intelligent control system and a control method thereof, and an oven, so as to solve the problems existing in the above-mentioned background technology.

[0009] The evaluation module includes a temperature evaluation unit and a volume evaluation unit. The temperature evaluation unit and the volume evaluation unit organize at least three sets of data on temperature and volume at different initial moments to form an optimization method for volume v with respect to temperature t. The optimization coefficients of the quadratic function are set to a, b, and c, respectively. The optimization method is as follows:

[0010] v=at 2 +bt+c

[0011] By substituting the three groups (t1, v1), (t2, v2), and (t3, v3) into the quadratic function, the values ​​of the optimal coefficients a, b, and c are obtained by solving the three sets of equations. Then, by substituting the specific values ​​of a, b, and c obtained into the quadratic function, the optimal inflection point is determined, which is recorded as (-b / 2a, 4ac-b 2 / 4a), the system automatically selects the best one.

[0021] The rotary baking mechanism includes two baking trays located in the upper and lower inner cavities of the oven body and two sets of connecting rods respectively connected to the outside of the two baking trays. Both ends of the two sets of connecting rods away from the baking trays are movably connected to the side turntables through bearings. The outer sides of the two side turntables are each installed with a rotating assembly located on the outer wall of the oven body;

[0022] The exhaust mechanism includes a steam blower, an air collecting hood installed at the air inlet at the bottom of the steam blower, and exhaust pipes installed at the air outlets on both sides of the top of the steam blower. The top end of the exhaust pipe passes through the wall of the oven body and is fixedly connected to the through hole opened in the center of the stove. A collecting assembly located directly above the top port of the exhaust pipe is installed on the top of the stove. The discharge end of the collecting assembly is fixedly connected to the waste collecting pipe, and the back of the waste collecting pipe is connected to the waste exhaust pipe.

[0023] Furthermore, the rotating assembly includes a fixed shaft that passes through the side wall of the oven body and is fixedly connected to the side turntable. The end of the fixed shaft away from the side turntable is fixedly connected to an end block of the rotating rod, and the other end block of the rotating rod is movably connected to the serrated rod. The bottom of the serrated rod is engaged with the outer edge of the gear, and the gear is always pulled on its surface through a limit sleeve movably connected thereto. The center of the gear is fixedly connected to the output shaft of the brake motor, and the tail of the brake motor is fixedly connected to a protective shell installed on the outer wall of the oven body.

[0024] Furthermore, the sawtooth rod rotates circumferentially along the surface of the gear meshing with it, and the surface of the sawtooth rod is closely abutted against the surface of the gear through the limiting sleeve.

[0029] S3. The exhaust mechanism is controlled by the control module to open, extracting the water vapor collected at the top of the oven body cavity, and directing the steam from the oven body into the combustion mechanism through the exhaust pipe;

[0030] S4. The steam is sprayed out through the central nozzle of the stove head, releasing heat to the bottom of the pot placed on top of the stove head for the second time and reducing the steam content in the box.

[0031] The technical effects and advantages of the present invention are as follows:

[0032] 1. The present invention is equipped with an information collection mechanism, an evaluation module, and a rotary baking mechanism. The information collection mechanism and the evaluation module determine the degree of baking of the food, and the speed of the rotary baking mechanism is regulated by the changes in the baking progress. When baking is completed, the control module controls the electric heating component to gradually stop supplying heat and controls the speed of the rotary baking mechanism to gradually decrease. This intelligent control of the heating supply of the oven body and the speed regulation of the rotary baking mechanism can effectively avoid overbaking, thereby evenly heating the surface of the baked food and reducing energy consumption.

[0033] 2. The present invention is provided with an information collection mechanism, an evaluation module and an exhaust mechanism to judge the baking degree of the food. When baking is completed, the exhaust mechanism is controlled by the control module to extract and discharge the water vapor gathered at the top of the oven body cavity, and the steam is introduced into the combustion mechanism from the exhaust pipe and sprayed out through the central nozzle of the stove head to release heat to the bottom of the pot body placed on the top of the stove head. On the one hand, it realizes the secondary utilization of heat, and on the other hand, it reduces the steam in the box, quickly lowers the temperature inside the box, and protects the user's safety when unpacking.

[0034] 3. The present invention is provided with a rotary baking mechanism, which is conducive to driving the two side turntables located on both sides of the baking tray to rotate in a circular manner through the braking of the rotating component, and the connecting rods fixedly connected to the two sides of the baking tray are connected to the side turntables through bearings, so that the baking tray always maintains a circular motion with the opening facing upward as the side turntables rotate in a circular manner, wherein the serrated rod rotates in a circular manner along the surface of the gear meshing therewith, and the surface of the serrated rod is closely abutted against the surface of the gear through a limiting sleeve, and at the same time, in the process of the serrated rod moving from the highest point to the lowest point of the gear surface, the serrated rod is converted into kinetic energy by its own gravitational potential energy and does not require a brake motor to provide a braking force, while in the process of the serrated rod moving from the lowest point to the highest point of the gear surface, a brake motor is required to provide a braking force, and thus the brake motor only needs to drive the gear to rotate half a circle each time, that is, to provide half the braking force, thereby simplifying the device structure and further reducing power loss.

[0035] 4. The present invention, by providing an information collection mechanism and an evaluation module, facilitates identifying the type of baked food through the image recognition module, thereby determining the volume change trend of that type of food during the baking process, namely, whether the volume expands or contracts. Once the type of baked food is determined, at least three sets of temperature and volume data are detected by the temperature detection module and the image recognition module, respectively. The evaluation module then performs algorithmic processing on the at least three sets of temperature and volume data at different initial moments, thereby forming a method for optimizing the volume v with respect to the temperature t, thereby obtaining the optimal relationship between the food temperature and volume, and thus achieving the optimal baking effect.

[0050] The technical solutions of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The electric heating intelligent control system for an oven and its control method, and the oven involved in the present invention are not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0051] Reference Figure 1-11 The present invention provides an oven electric heating intelligent control system and a control method thereof, an oven, and an oven electric heating intelligent control system, comprising an electric heating component 2 installed inside an oven main body 1, and heating the inside of the oven main body 1 through the electric heating component 2.

[0052] A rotary baking mechanism 3 is provided on both sides of the inner cavity and outer wall of the oven body 1. An exhaust mechanism 4 located on the top of the rotary baking mechanism 3 is installed at the top of the inner cavity of the oven body 1. A combustion mechanism 5 connected to the exhaust mechanism 4 is installed at the top of the outer wall of the oven body 1.

[0053] As a further improvement: the oven body 1 further includes an information collection mechanism 6, an evaluation module 7 and a control module 8; wherein,

[0054] The information collection unit 6 is used to obtain and collect relevant information and generate a data set;

[0055] The evaluation module 7 is used to analyze and process the received information data group and obtain the optimal solution with the help of an algorithm;

[0056] The control module 8 receives the cut-off control inflection point signal, obtains the cut-off control instruction at the optimal time, and controls the electric heating component 2, the rotary baking mechanism 3, and the exhaust mechanism 4 respectively; wherein the control method is as follows:

[0057] The degree of baking of the food is determined by the information collection unit 6 and the evaluation module 7. The speed of the rotary baking mechanism 3 is regulated based on the baking progress. That is, the speed of the rotary baking mechanism 3 is adaptively adjusted as the baking progresses. When baking is completed, the control module 8 controls the electric heating component 2 to gradually stop supplying heat and controls the rotating component 304 to stop braking. As a result, the baking tray 301 containing the food no longer moves in a circular motion.

[0058] The exhaust mechanism 4 is controlled to open by the control module 8, and the water vapor gathered at the top of the oven body cavity is extracted, and the steam from the box of the oven main body 1 is introduced into the combustion mechanism 5 through the exhaust pipe 403, and is sprayed out through the central nozzle of the stove head 502, so as to release heat to the bottom of the pot body placed on the top of the stove head 502 for the second time, and reduce the steam content in the box.

[0059] Reference Figure 6-8 The rotary baking mechanism 3 includes two baking trays 301 located in the upper and lower inner cavities of the oven body 1 and two groups of connecting rods 302 respectively connected to the outside of the two baking trays 301. The two ends of the two groups of connecting rods 302 away from the baking trays 301 are movably connected to the side turntables 303 through bearings. The outer sides of the two side turntables 303 are each installed with a rotating assembly 304 located on the outer wall of the oven body 1;

[0060] The rotating assembly 304 includes a fixed shaft 3041 that passes through the side wall of the oven body 1 and is fixedly connected to the side turntable 303. The end of the fixed shaft 3041 away from the side turntable 303 is fixedly connected to an end block of a rotating rod 3042. The other end block of the rotating rod 3042 is movably connected to a sawtooth rod 3043. The bottom of the sawtooth rod 3043 is meshed with the outer edge of the gear 3044, and the gear 3044 is always pulled on its surface by a limit sleeve 3045 movably connected thereto. The center of the gear 3044 is fixedly connected to the output shaft of the brake motor 3046. The tail of the brake motor 3046 is fixedly connected to a protective housing installed on the outer wall of the oven body 1.

[0061] During use, the two side turntables 303 located on both sides of the baking tray 301 are driven to rotate in a circular manner through the rotation assembly 304, and the connecting rods 302 fixedly connected to the two sides of the baking tray 301 are connected to the side turntables 303 through bearings. As a result, the baking tray 301 always maintains a circular motion with the opening facing upward as the side turntables 303 rotate in a circular manner, wherein the serrated rod 3043 rotates in a circular manner along the surface of the gear 3044 meshing therewith, and the surface of the serrated rod 3043 is closely abutted against the surface of the gear 3044 by the limiting sleeve 3045. At the same time, when the serrated rod 3043 moves from the highest point to the lowest point on the surface of the gear 3044, the serrated rod 3043 converts its own gravitational potential energy into kinetic energy, and no braking force is required from the brake motor 3046. However, when the serrated rod 3043 moves from the lowest point to the highest point on the surface of the gear 3044, the brake motor 3046 is required to provide braking force. Therefore, the brake motor 3046 only needs to drive the gear 3044 to rotate half a circle each time, that is, to provide half the braking force.

[0062] In this embodiment, it should be specifically explained that the two groups mentioned above are quantitative nouns, and two objects of the same type and with the same structure are divided into the same group, and the two groups contain four of the same objects.

[0063] Reference Figure 5-11 The combustion mechanism 5 includes a stove body 501 mounted on the top surface of the outer wall of the oven body 1 and burners 502 mounted on both sides of the top of the stove body 501;

[0064] The exhaust mechanism 4 includes a steam blower 401, an air collecting hood 402 installed at the bottom air inlet of the steam blower 401, and an exhaust pipe 403 installed at the air outlets on both sides of the top of the steam blower 401. The top end of the exhaust pipe 403 passes through the wall of the oven body 1 and is fixedly connected with the through hole opened in the center of the stove head 502. A collecting assembly 503 located directly above the top port of the exhaust pipe 403 is installed on the top of the stove head 502. The discharge end of the collecting assembly 503 is fixedly connected with the waste collecting pipe 504, and the back of the waste collecting pipe 504 is connected to the waste discharge pipe.

[0065] During use, the steam blower 401 blows air, and the water vapor located in the cavity of the oven main body 1 flows through the wind collecting hood 402, the steam blower 401 and the exhaust pipe 403 in sequence, and is finally discharged upward at the top port of the exhaust pipe 403. The ejected steam can be used to assist in heating the bottom of the iron pot located on the top of the stove head 502, thereby reducing the supply of a small amount of gas. The steam in the inner cavity of the oven main body 1 is released and the temperature is reduced. At the same time, the steam discharged upward through the top end of the exhaust pipe 403 passes through the bottom hood 5032 and the top hood 5031 and condenses on their inner walls. It is respectively collected in the grooves at the bottom of the inner walls of the top hood 5031 and the bottom hood 5032, and is introduced into the waste collecting pipe 504 through the guide pipe 5033. Then, the waste liquid inside the waste collecting pipe 504 is discharged to avoid the condensate from flowing back. After the exhaust is completed, the steam blower 401 is further closed, and the air inlet pipe 404 is opened to allow outside air to enter. The user can then open the oven and take out the food.

[0066] Reference Figure 1-3 The information collection mechanism 6 includes a temperature detection module 601, an image recognition module 602 and a volume detection module 603; wherein,

[0067] The temperature detection module 601 detects the temperature of the food surface and obtains a temperature value t at a certain moment, including at least three groups t1, t2, and t3;

[0068] The image recognition module 602 determines the type of food and more accurately evaluates the subsequent temperature and volume change trends of the food to determine the inflection point of (volume, temperature);

[0069] The volume detection module 603 detects the volume of the food and obtains a volume value v at a certain moment, which includes at least three groups v1, v2, and v3;

[0070] During use, the image recognition module 602 locks the type of baked food to determine the volume change trend of the type of food during the baking process, that is, whether the volume expands or contracts. After the type of baked food is determined, the temperature detection module 601 and the volume detection module 603 detect at least three sets of data consisting of temperature and volume.

[0071] In this embodiment, it should be specifically explained that the image recognition module 602 includes a picture input unit 6021, a graphic database 6022, a graphic determination unit 6023, a language prompt unit 6024 and a manual input unit 6025;

[0072] The image of food is collected by the image input unit 6021 and imported into the graphic database 6022. The collected image is compared with the food stored in the graphic database 6022 and judged by the graphic judgment unit 6023. The output value of the recognition is announced by the language prompt unit 6024 to prompt the user whether the recognition is correct. If the recognition is not correct, the food name is input through the manual input unit 6025 to increase the accuracy and error tolerance of the image recognition.

[0073] The graphic determination unit 6023 includes a color determination group 60231, a light and dark determination group 60232, and a shape determination group 60233. Through these three determination groups, the determination basis is increased, the response speed is improved, and the selection speed is thereby improved.

[0074] The evaluation module 7 includes a temperature evaluation unit 701 and a volume evaluation unit 702; wherein,

[0075] The temperature evaluation unit 701 and the volume evaluation unit 702 organize at least three sets of data on temperature and volume at different initial moments to form an optimization method for volume v with respect to temperature t. The optimization coefficients of the quadratic function are set to a, b, and c, respectively. The optimization method is as follows:

[0076] v=at 2 +bt+c

[0077] By substituting the three groups (t1, v1), (t2, v2), and (t3, v3) into the quadratic function, the values ​​of the optimal coefficients a, b, and c are obtained by solving the three sets of equations. Then, by substituting the specific values ​​of a, b, and c obtained into the quadratic function, the optimal inflection point is determined, which is recorded as (-b / 2a, 4ac-b 2 / 4a), the system automatically selects the best one.

[0078] During use, when the control module 8 obtains the optimal inflection point signal, it controls the output shaft speed of the brake motor 3046, and realizes that the rotating component 304 drives the side turntable 303 and the baking tray 301 to perform corresponding circular motion speed changes, thereby evenly heating the food stored in the baking tray 301 in the cavity of the oven main body 1. At the inflection point, the rotary baking mechanism 3 stops braking. In addition, the speed of the rotary baking mechanism 3 shows a positive change with the change of the function slope. In addition, when the optimal inflection point signal is obtained, the control module 8 controls the electric heating component 2 to gradually stop supplying heat, and controls the exhaust mechanism 4 to ventilate the cavity of the oven main body 1.
