[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-6As shown, a cooking device includes a base 1 and a stove 2. The base 1 has an air duct inside, and the stove 2 is positioned on top of the base 1. The stove 2 has an upward-opening combustion chamber 21. A notch 24 for avoiding the handle of a pot 6 is provided on one side of the top of the stove 2. A heating element is located at the bottom of the combustion chamber 21. A collection cavity 25 is formed by the hollow side wall of the stove 2. Several collection ports 26 connected to the collection cavity 25 are distributed circumferentially along the inner side of the top of the stove 2. The collection cavity 25 is connected to the air inlet of the air duct. The top of the stove 2 is configured to support the pot 6 below the collection ports 26. In use, the pot 6 can be placed on top of the stove 2, and the handle of the pot 6 can extend through the notch 24 to the outside for the user to grip. The air outlet of the duct can be connected to the kitchen exhaust duct. When the heating element heats the food in the cookware 6, the negative pressure formed in the exhaust duct will draw the oil fumes and water vapor generated by heating the food in the cookware 6. The oil fumes and water vapor that float upwards will flow into the collection chamber 25 through the surrounding collection port 26, and then enter the exhaust duct for centralized treatment through the air duct. This reduces the spread of oil fumes and helps keep the kitchen clean and tidy. At the same time as the oil fumes and water vapor are recovered, the collection port 26 will also draw in a large amount of air. When the large amount of air flows through the collection chamber 25, it will carry away the heat from the side wall of the burner 2, thereby reducing the temperature of the outer wall of the burner 2 during cooking. This will prevent operators from being burned by touching the high-temperature burner 2 and improve the safety of use.

[0030] Specifically, the heating component can use fuel or electricity as its energy source, such as a coal-fired furnace or a gas-fired furnace. In this embodiment, it is preferably driven by electricity.

[0031] Furthermore, the air duct includes a main flow duct 12 and several secondary flow ducts 13. The secondary flow ducts 13 are evenly distributed along the length of the base 1 on the upper half of the base 1. The secondary flow ducts 13 are arranged horizontally and parallel to each other. The main flow duct 12 is arranged along the length of the base 1 on the lower half of the base 1. The secondary flow ducts 13 are all connected to the main flow duct 12. One end of the main flow duct 12 can be connected to the kitchen exhaust duct. There are several stoves 2. The stoves 2 are evenly distributed above the secondary flow ducts 13. The bottom of each stove 2 is provided with a connecting pipe 27. The collection chamber 25 is connected to the corresponding secondary flow duct 13 through the connecting pipe 27. The main flow duct 12 and the secondary flow ducts 13 are arranged in a wing-like manner to expand the coverage of the air duct so as to realize multi-point oil fume extraction and take into account the use scenario of large-scale cooking in commercial kitchens.

[0032] Furthermore, a controller 3 is provided on one side of the base 1. The base 1 has an installation cavity 14 above the secondary flow channel 13. Several through-holes 11, connecting to the installation cavity 14, are opened on the top of the base 1. These through-holes 11 are evenly distributed along the length of the secondary flow channel 13. Several weighing sensors 4 are provided on the bottom wall of the installation cavity 14, evenly distributed below the through-holes 11. The controller 3 is electrically connected to the heating element and the weighing sensors 4. The furnace 2 is movably fitted into the through-holes 11, with its bottom abutting against the corresponding weighing sensor 4. During use, the controller 3 will preset multiple cooking programs. Different cooking programs correspond to different weighing weights, and different weighing weights correspond to different dishes. For example, claypot rice can be either preserved meat claypot rice or beef and egg claypot rice, depending on the ingredients. Assuming the sum of the ingredients and the weight of the pot 6 for preserved meat claypot rice is A1, A1 corresponds to program B1, and beef and egg claypot rice... The sum of the weight of the ingredients and the pot 6 in the claypot rice is A2. The program corresponding to A2 is B2. Taking preserved meat claypot rice as an example, when the pot 6 containing the ingredients is placed on top of the stove 2, the pot 6 will press down on the stove 2. The stove 2 will apply pressure to the weighing sensor 4 at the bottom, causing the weighing sensor 4 to acquire weight data A1 and send the weight data A1 to the controller 3. After receiving the weight data A1, the controller 3 will start the heating component, which will heat according to the program B1. The ingredients in the pot 6 will be cooked at the preset temperature and time. A2 is similar to B2. This eliminates the burden of operators having to intervene in the ignition and temperature adjustment throughout the process, realizing intelligent cooking of quantitative ingredients according to fixed parameters. It avoids the random interference of manual operation, ensures the quality of products during busy periods, and better balances cooking efficiency and energy consumption. The weighing sensor 4 and the controller 3 can be purchased through market channels and will not be described in this embodiment.

[0033] Furthermore, the heating assembly includes a bracket 51 and heating wires (not shown in the attached drawings). The bracket 51 is fixedly installed at the bottom of the furnace chamber 21. A concentric groove 52 is coaxially provided on the upper side wall of the bracket 51. The heating wires are evenly distributed in the concentric grooves 52 and are electrically connected to the controller 3 so that the controller 3 can control the evenly distributed heating wires to heat up, so as to evenly heat the pot 6 above and achieve a cooking effect with uniform heat.

[0034] Furthermore, a furnace temperature probe 7 is fitted through the middle of the inner wall of the support 51. The furnace temperature probe 7 is electrically connected to the controller 3 so as to detect the heating temperature at the top of the support 51. This allows the controller 3 to adjust the heating wire according to the temperature, ensuring that the heating temperature is within a reasonable range and achieving precise control of the heat.

[0035] Furthermore, the support 51 is an upward-opening hollow structure, and the diameter of its inner cavity gradually decreases from top to bottom. The concentric groove 52 is coaxially opened on the inner wall of the support 51 so that the distribution area of ​​the heating wire is adapted to the lower side wall of the cookware 6 with a curved surface, which is conducive to evenly heating the flat bottom wall and the curved side wall of the bottom of the cookware 6, so that the food in the cookware 6 is heated more evenly and the cooking effect is ensured.

[0036] Furthermore, the cooking device also includes a pot 6, which is mounted on top of the stove 2. The inner wall contour of the support 51 is adapted to the lower side wall contour of the pot 6, and the vertical distance between the two is 15mm-35mm. Within this range, the heating efficiency of the heating wire to the bottom of the pot 6 can be ensured, while also preventing the pot from burning due to excessive heat.

[0037] Furthermore, the diameter of the support 51 is smaller than the inner diameter of the furnace chamber 21. The periphery of the support 51 is spaced from the inner wall of the furnace chamber 21. The inner wall of the furnace chamber 21 is provided with an annular protrusion 22 along the circumferential direction. The protrusion 22 is located below the collection port 26 and is used to support the pot 6. The bottom of the inner side wall of the protrusion 22 extends downward with a surrounding plate 220. The lower end of the surrounding plate 220 is connected to the upper edge of the support 51. The inner wall of the furnace chamber 21, the lower side wall of the protrusion 22, the outer side wall of the surrounding plate 220, and the outer side wall of the support 51 form a heat insulation cavity a. The heat insulation cavity a is filled with heat insulation material 9 to reduce the conduction of high temperature in the furnace chamber to the outer wall of the furnace slab 2, further lowering the temperature of the outer wall of the furnace slab 2, while maintaining the high temperature in the furnace chamber. The heat insulation material 9 can be made of materials such as rock wool, glass wool, and aluminum silicate fiber.

[0038] Furthermore, the top of the base 1 is connected to a pot temperature probe (not shown in the attached diagram) via an electric wire. The pot temperature probe is electrically connected to the controller 3. The pot temperature probe can be inserted into the pot 6 to detect the temperature of the food inside the pot 6. This allows the controller 3 to further adjust the heating power and pattern of the heating wire according to the pot temperature, thereby achieving precise temperature control and improving the cooking effect.

[0039] Furthermore, the cooking device also includes a mesh screen 8. Several support blocks 23 are distributed circumferentially on the inner wall of the furnace chamber 21. The mesh screen 8 is mounted above the heating element through the support blocks 23. The heat from the heating wire can be transferred to the lower side wall of the pot 6 through the holes of the mesh screen 8. The mesh screen 8 can effectively isolate foreign objects or limbs, preventing foreign objects from falling onto the support 51 or limbs from touching the heating wire, thus improving the safety of the cooking device.
