Description

Technical Field

[0001] The present invention relates to the technical field of intelligent grilling devices, and in particular to an intelligent grilling device capable of switching between multiple cooking modes. Background Art

[0002] Grills are commonly used electric kitchen appliances in people's daily lives, which are used to grill food. Grills are commonly used electric kitchen appliances in people's daily lives, which are used to grill food.

[0003] According to a new type of smokeless grill mentioned in the invention patent with Chinese patent application number 202110618910.6, the main purpose of the new type of smokeless grill when in use is to solve the problems of the existing smokeless grill, such as the complex structure of the smoke treatment device, poor oil fume absorption effect and inconvenient cleaning of the grilling pan. However, when the new type of smokeless grill is in use, the fixed depth grilling plate cannot perfectly adapt to ingredients of different thicknesses. Thin ingredients such as bacon are easily over-squeezed and lose juice, and thick ingredients such as tomahawk steaks may be heated unevenly and difficult to cook in the center. As a result, the grill cannot adjust the depth of the grilling plate according to the thickness of the ingredients, and cannot dynamically adjust the pressure between the grilling plate and the ingredients according to the expansion or contraction of the ingredients during the grilling process.

[0019] Compared with the prior art, the present invention provides an intelligent grill with multiple cooking mode switches, which has the following beneficial effects:

[0020] 1. This intelligent grill with multiple cooking mode switches utilizes an intelligent grilling system. During use, the intelligent sensing module first uses a high-precision non-contact ultrasonic ranging sensor to emit a detection beam before the upper and lower bases are fully closed. This sensor measures the initial thickness of the food between the lower and upper grilling plates before it is compressed during cooking. After the upper and lower bases are fully closed, a pressure sensor measures the pressure distribution of the food at the contact surfaces of the lower and upper grilling plates in real time. The central processing unit receives the ranging and pressure data in turn. A thickness-pressure fusion algorithm calculates the actual average thickness and thickness of the food based on the ranging and pressure distribution data received by the central unit. The dynamic depth setting unit then calculates the desired grilling depth based on the food characteristics and the user-selected cooking mode. Finally, the lifting assembly adjusts the contact pressure and distance between the upper and lower grilling plates, dynamically adjusting the distance between the lower and upper grilling plates based on the food characteristics.

[0021] 2. The intelligent grill with multiple cooking mode switching is equipped with a lifting assembly. When in use, the stepper motor is operated by the precise execution module. The output shaft of the stepper motor will drive the rotating drum to rotate. Since the limit slide has an indirect limiting effect on the threaded rotating rod, the threaded rotating rod can be pushed upward inside the rotating drum. The distance between the limit slide and the bottom of the upper base can be adjusted to achieve the purpose of adjusting the distance between the upper and lower grilling plates. The upper grilling plate is installed on the top of the limit slide. Through the lifting assemblies set at the four corners, the lifting assemblies at different positions can adjust the inclination angle of the upper grilling plate in real time according to the uneven thickness of the food through the precise execution module.

[0022] 3. The intelligent grill with multiple cooking mode switching is provided with a plug-in assembly. When in use, the upper grilling plate is installed by aligning the plug-in block and the U-shaped block with the plug-in slot and the U-shaped slot respectively, so that the limit column and the fixed block limit the plug-in block and the U-shaped block, thereby stably fixing the upper grilling plate inside the upper base, thereby facilitating quick disassembly and cleaning of the upper grilling plate.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-7 , an intelligent grill with multiple cooking mode switching includes a lower base 1, an upper base 2 is movably installed on the top of the lower base 1, a lower grilling plate 5 and an upper grilling plate 6 are respectively provided inside the lower base 1 and the upper base 2, a smart control panel 4 is provided on the top of the lower base 1, and an intelligent grilling system is provided inside the lower base 1, the intelligent grilling system including an intelligent sensing module, an intelligent decision-making module, a precise execution module and a cooking mode engine, and a lifting component 12 is movably installed inside the upper base 2;

[0033] The lifting assembly 12 includes a stepper motor 121, and the stepper motor 121 is fixedly installed inside the upper base 2. A rotating cylinder 122 is provided at the output shaft of the stepper motor 121. The internal thread of the rotating cylinder 122 is connected to a threaded rotating rod 123. A multi-directional hinge block 19 is provided at the top of the threaded rotating rod 123. A plug-in column 20 is provided at the top of the multi-directional hinge block 19. A plug-in cylinder 21 is provided on the outside of the plug-in column 20. A positioning plate 22 is provided on the top of the positioning plate 22. A limiting slide 11 is provided on the top of the limiting slide 11. A plug-in assembly 16 is provided on the top of the limiting slide 11.

[0034] In the case implementation, before the upper base 2 and the lower base 1 are completely closed, a detection beam is emitted by a high-precision non-contact ultrasonic ranging sensor 7 to measure the initial thickness of the food between the lower grilling plate 5 and the upper grilling plate 6 before it is fried or compressed. The pressure sensor 18 also detects in real time the pressure distribution of various parts of the food on the contact surface between the lower grilling plate 5 and the upper grilling plate 6.

[0035] In the case implementation, (1) central processing unit: receives distance measurement and pressure data, (2) thickness-pressure fusion algorithm: the central processing unit combines the initial thickness data and real-time pressure distribution to accurately calculate the actual average thickness, shape contour (such as whether the thickness is uneven) and firmness of the food, (3) dynamic depth setting: the algorithm automatically calculates the optimal target grilling depth based on the calculated food characteristics and the cooking mode selected by the user; depth assurance: optimal contact area: maximizes and evens the contact between the grilling plate and the surface of the food to improve heat conduction efficiency, moderate pressure: applying just the right amount of pressure can not only promote the Maillard reaction to form a perfect crust, but also avoid excessive squeezing that causes juice loss (especially for thin slices or tender meat) or hinders internal heating (for thick meat); reserved expansion space: reserves space for the natural expansion of the food during heating.

[0036] In the case implementation, the unit processing unit sends a command to the stepping motor 121, and the lifting component 12 drives the upper grilling plate 6 to adjust the depth. At the same time, the displacement distance of the upper grilling plate is detected by the displacement sensor.

[0037] In the case implementation, the cooking mode database contains a large number of programs optimized by cooking experts, covering steaks, pork chops, chicken breasts, fish fillets, hamburger patties, bacon, vegetable skewers, panini, etc.; and through the one-click matching unit, users can select the type of ingredients and the desired degree of doneness, and automatically call the best cooking program for the ingredients. Finally, through the real-time feedback optimization unit, during the cooking process, ADS can continuously monitor the possible shrinkage or shape changes of the ingredients, monitor the cooking temperature of the ingredients through infrared non-contact, and dynamically fine-tune the temperature, time or pressure through the real-time monitoring data (depth, pressure, core temperature) to ensure that the cooking results of the ingredients meet the expected effects.

[0038] In summary, the intelligent grilling device with multiple cooking mode switches is provided with an intelligent grilling system. During use, the intelligent sensing module first transmits a detection beam through a high-precision non-contact ultrasonic distance sensor 7 before the upper base 2 and the lower base 1 are fully closed. This sensor measures the initial thickness of the food between the lower grilling plate 5 and the upper grilling plate 6 before it is grilled and compressed. After the upper base 2 and the lower base 1 are fully integrated, the pressure sensor 18 detects the pressure distribution of various parts of the food on the contact surface between the lower grilling plate 5 and the upper grilling plate 6 in real time. The distance and pressure data are sequentially received by the central processing unit. A thickness-pressure fusion algorithm calculates the actual average thickness of the food and the thickness of the food based on the distance and pressure distribution data received by the central unit. The dynamic depth setting unit calculates the characteristics of the food and the cooking mode selected by the user to calculate the grilling depth of the food. Finally, the lifting assembly 12 adjusts the contact pressure and distance between the upper grilling plate 6 and the food, thereby dynamically adjusting the distance between the lower grilling plate 5 and the upper grilling plate 6 according to the characteristics of the food.

[0039] In addition, by setting up the lifting assembly 12, when in use, the stepping motor 121 is operated through the precise execution module, and the output shaft of the stepping motor 121 will drive the rotating drum 122 to rotate. Since the limiting slide 11 has an indirect limiting effect on the threaded rotating rod 123, the threaded rotating rod 123 can be pushed upward inside the rotating drum 122, and the distance between the limiting slide 11 and the bottom of the upper base 2 can be adjusted to achieve the purpose of adjusting the distance between the upper frying plate 6 and the lower frying plate 5. The upper frying plate 6 is plugged into and installed on the top of the limiting slide 11. Through the lifting assemblies 12 set at the four corners, the lifting assemblies 12 at different positions can adjust the inclination angle of the upper frying plate 6 in real time according to the uneven thickness of the food through the precise execution module according to the different thickness positions of the food.

[0040] Furthermore, by providing the plug-in assembly 161, when in use, the upper grilling plate 6 is installed by aligning the plug-in block 165 and the U-shaped block 166 with the plug-in groove 163 and the U-shaped groove 164 respectively, so that the limiting column 162 and the fixing block 161 limit the plug-in block 165 and the U-shaped block 166, thereby being able to stably fix the upper grilling plate 6 inside the upper base 2, thereby facilitating the quick disassembly and cleaning of the upper grilling plate 6.
