Description

Technical Field

[0001] The present invention relates to the technical field of automatic cooking machines, and in particular to a furnace core for an automatic cooking machine and the automatic cooking machine using the furnace core. Background Art

[0002] With the continuous improvement of science and technology, automation equipment has been applied to various fields of social life. It has the advantages of replacing manual operation, saving human resources, reducing labor intensity and improving work efficiency. As a modern kitchen automation equipment, automatic cooking machines / automatic cooking robots can automatically complete various cooking methods such as frying, stir-frying, cooking, deep-frying, blasting, stewing, and boiling instead of manual work. With the continuous emergence of different types of automatic cooking machines / automatic cooking robots, it has not only improved cooking efficiency but also reduced the labor intensity of chefs. While reducing the cost of the catering industry, it has also promoted the development of Chinese food standardization, so that Chinese food companies can reduce costs and increase efficiency, ensure the consistency of dishes in different stores, and thus gain a greater advantage in the fierce market competition. In order to achieve the standardization of Chinese food, in addition to improving the level of standardized management, the performance of automated cooking equipment also plays a vital role.

[0003] The existing furnace core for automatic cooking machines usually heats the pot in the furnace by passing a high-frequency current through the electromagnetic coil of the heater to generate electromagnetic induction. When the electromagnetic coil heats the pot, the high-frequency current passing through the coil has a skin effect, so the coil wire is usually composed of multiple strands of insulated thin wires (Litz wire, enameled wire) to increase the effective surface area of ​​the conductor. However, the temperature range of the insulating paint material on the conductor surface of the commonly used coil wire is 150-180°C, and the electromagnetic coil itself generates a lot of heat when heating the pot. However, the existing furnace core for automatic cooking machines usually does not provide a forced heat dissipation design for its heater electromagnetic coil, that is, its heater electromagnetic coil still uses natural heat dissipation, and its heat dissipation effect is poor, which easily causes the insulating paint temperature of the coil wire to fail due to exceeding the temperature resistance range, so that the impedance of the coil wire to the high-frequency current passing through increases accordingly, and its self-heating increases accordingly, causing the automatic cooking machine to need to be frequently shut down for cooling or even damaged, affecting the working efficiency and service life of the automatic cooking machine, and failing to meet the high-intensity use requirements of commercial equipment.

[0004] In addition, due to the small internal space of the main unit of the automatic cooking machine, traditional cooling fans are not easy to install; and traditional cooling fans are difficult to solve the problem of cooling air being disturbed by cooking fumes when flowing to the heater electromagnetic coil, resulting in poor cooling effect. If a sealed air duct reaching the heater electromagnetic coil is laid in the narrow main unit, it will be even more difficult to install.

[0005] At the same time, during the process of turning and frying the pot, the temperature sensor on the rotating pot is difficult to connect to the external temperature control device using traditional cables due to the easy cable entanglement, and it is not easy to transmit the temperature measurement signal to the outside. In addition, the traditional furnace core used in automatic cooking machines requires a motor and a reducer to drive the pot or the spatula inside the pot to rotate. The drive device and transmission device have complex structures and large volumes. The moving parts of the transmission device, such as the reduction gears, are noisy and easy to wear, resulting in multiple parts of the transmission device requiring regular lubrication and maintenance. In addition, the wall frame used in the furnace core of the automatic cooking machine must not only meet the high temperature resistance characteristics but also have a certain strength.

[0072] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figure 1-10 The present invention is further described in detail with reference to the accompanying drawings and embodiments.

[0073] Please also read Figure 1-10The furnace core for an automatic cooking machine provided by the present invention comprises a pot core 1 located in an inner layer and a furnace 2 located in an outer layer (that is, the furnace 2 is sleeved on the outside of the pot core 1), a shovel 13 arranged inside the pot core 1, a driving device 3 arranged at the bottom end of the furnace 2 and used to drive the pot core 1 to rotate, and a first flip shaft 5 and a second flip shaft 6 arranged on both sides of the furnace 2 relatively; the first flip shaft 5 and the second flip shaft 6 are hollow inside and respectively form an air inlet 51 and an air outlet 61.

[0074] The furnace 2 includes:

[0075] The chamber wall 21 has a hollow structure inside; the chassis 22 is connected to the bottom end of the chamber wall 21; the air inlet duct 271 and the air outlet duct 272 are relatively arranged on both sides of the chamber wall 21, and the air inlet duct 271 is connected to the air inlet 51, and the air outlet duct 272 is connected to the air outlet 61; the buffer air chamber 4 is arranged below the chassis 22 (i.e., the bottom end of the chamber wall 21); a pair of heater cavities 273 are relatively arranged between the air inlet duct 271 and the air outlet duct 272 on both sides of the furnace 2, and the air inlet side of the heater cavity 273 is connected to the air inlet duct 271 through the buffer air chamber 4, and the air outlet side of the heater cavity 273 is connected to the air outlet duct 272; the heater coil 7 is arranged in the heater cavity 273;

[0076] A plurality of heat dissipation fans 8 allow heat dissipation gas to enter from the air inlet 51 , pass through the air inlet duct 271 , the buffer air chamber 4 , the heater cavity 273 , the air outlet duct 272 in sequence, and finally be discharged from the air outlet 61 .

[0077] Please also read Figure 1-10 The present invention provides a stove core for an automatic cooking machine, wherein a pot 1 is used as a container of the stove core for accommodating food materials, and a furnace 2 is used as a main body of the stove core for connecting to a host of the automatic cooking machine, driving the pot 1 to flip, driving the pot 1 to rotate, and installing a heater coil 7 for heating the pot 1.

[0078] Please also read Figure 1 , 5 -8, in this embodiment, the air inlet duct 271 is connected to the buffer air chamber 4; a pair of heater cavities 273 are arranged on both sides of the furnace 2 and are staggered with the air inlet duct 271 and the air outlet duct 272, and the air inlet side of the heater cavity 273 is the side of the heater cavity 273 close to the bottom end of the furnace 2 (furnace 2), and the air outlet side of the heater cavity 273 is the other side of the heater cavity 273 away from the bottom end of the furnace 2 and close to the top end of the furnace 2. The corresponding air inlet sides of the pair of heater cavities 273 are respectively connected to the two sides of the buffer air chamber 4, and the corresponding air outlet sides of the pair of heater cavities 273 are respectively connected to the two sides of the portion of the air outlet duct 272 away from the bottom end of the furnace 2 (chamber wall 21) and close to the top end of the furnace 2 (chamber wall 21).

[0079] Please also read Figure 1 , 5 -10. In the present embodiment, a plurality of cooling fans 8 are arranged in the buffer air chamber 4 and are distributed at intervals along the circumferential direction of the furnace 2 on the peripheral side of the bottom end of the furnace 2, so as to blow the cooling gas entering the buffer air chamber 4 through the air inlet 51 and the air inlet duct 271 in sequence into the heater cavity 273.

[0080] Please also read Figure 1 , 5 -10. As a preferred implementation mode of this embodiment, the heat dissipation fan 8 adopts a micro fan, and multiple heat dissipation fans 8 (micro fans) are evenly spaced along the circumference of the furnace 2 and distributed below the chassis 22 at the bottom end of the furnace 2 (chamber wall 21). The heat dissipation gas entering the buffer air chamber 4 is blown by multiple heat dissipation fans 8 (micro fans) and flows through the heater cavity 273 along the axial direction of the furnace 2 close to the top of the furnace 2 in multiple paths, and blows across the surface of the furnace 2 in close contact with the heater coil 7. This has a better heat dissipation effect on the heater coil 7 in the heater cavity 273 and makes the heat dissipation of the heater coil 7 more uniform. At the same time, the integration of the furnace core can be improved, saving the valuable space occupied by the heat dissipation fan installed in the main unit of the automatic cooking machine using the furnace core.

[0081] In other embodiments, only one cooling fan 8 operating in a blowing or exhausting mode may be provided.

[0082] Please also read Figure 1-7 In this embodiment, the first flip shaft 5 is arranged on one side of the furnace 2 (chamber wall 21) corresponding to the air inlet duct 271, and an air inlet 51 is provided inside the first flip shaft 5, which passes through the first flip shaft 5 along its axial direction and is connected to the air inlet duct 271; the second flip shaft 6 is arranged on the other side of the furnace 2 (chamber wall 21) corresponding to the air outlet duct 272 and is coaxially arranged with the first flip shaft 5, and an air outlet 61 is provided inside the second flip shaft 6, which passes through the second flip shaft 6 along its axial direction and is connected to the air outlet duct 272.

[0083] When the furnace core provided by the present invention is used in an automatic cooking machine, the first flip axis 5 and the second flip axis 6 are respectively matched with a pair of bearings provided on the main unit of the automatic cooking machine (not shown in the figure), so that the furnace 2 can be connected to the main unit by rotating around the first rotation axis X that coincides with the first flip axis 5 and the second flip axis 6 (i.e., flipping up and down).

[0084] Please also read Figure 1 , 5-10, in this embodiment, the furnace 2 is cylindrical, one axial end of the furnace 2 (chamber wall 21) is the top of the furnace 2, and the top of the furnace 2 is open; the other axial end of the furnace 2 (chamber wall 21) is the bottom of the furnace 2, and the bottom of the furnace 2 is closed. The heater coil 7 is attached to the outer side of the inner wall of the furnace 2 (chamber wall 21), that is, in the heater cavity 273, and the heater coil 7 is an electromagnetic heating coil.

[0085] When the heater coil 7 is working, a high-frequency current is passed through its coil, so that the heater coil 7 as a whole generates an alternating magnetic field. The alternating magnetic field generates eddy currents on the pot inner body 1. Affected by the conductivity of the pot inner body 1, the eddy currents generated on the pot inner body 1 will have a thermal effect on the pot inner body 1, thereby achieving electromagnetic eddy current heating of the pot inner body 1 in the furnace 2 by the heater coil 7 on the outer side of the inner lining 212 of the furnace wall of the furnace 2.

[0086] When the heater coil 7 is working, the colder gas in the external environment passes through the main unit of the automatic cooking machine and enters the buffer air chamber 4 at the bottom of the furnace 2 as the heat dissipation gas through the air inlet 51 inside the first turning shaft 5 and the air inlet duct 271 on one side of the furnace 2. Then, a plurality of heat dissipation fans 8 arranged in the buffer air chamber 4 blow the heat dissipation gas entering the buffer air chamber 4 into a pair of heater cavities 273 on both sides of the furnace 2, which are respectively adjacent to the air inlet duct 271 and close to the air inlet side of the bottom of the furnace 2. The heat dissipation gas flows in the heater cavity 273 along the axial direction of the furnace 2 away from the bottom of the furnace 2 (and close to the top of the furnace 2 relative to the buffer air chamber 4), thereby dissipating the heat of the heater coil 7 on the outer surface of the chamber wall lining 212 of the furnace 2 in the heater cavity 273. Finally, the hot air (i.e., the hot air heated by the heater coil 7) enters the air outlet duct 272 from the air outlet side of the heater cavity 273 close to the top end of the furnace 2 (i.e., away from the bottom end of the furnace 2), and is then discharged to the external environment through the air outlet duct 272 on the other side of the furnace 2, the air outlet 61 inside the second flip shaft 6, and the inside of the main unit in sequence.

[0087] The above air inlet 51, air inlet duct 271, buffer air chamber 4 and the cooling fan 8 therein, a pair of heater cavities 273, air outlet duct 272 and air outlet 61 constitute an air duct structure disposed outside the furnace 2 for ventilating and cooling the heater coil 7 in the pair of heater cavities 273 and the external environment of the automatic cooking machine. The air duct structure works continuously according to the above steps, so that the heater coil 7 can achieve continuous and efficient ventilation and heat dissipation while performing electromagnetic eddy current heating of the pot 1 in the furnace 2, thereby avoiding the failure of the insulation paint of the coil wire due to the poor heat dissipation effect of the electromagnetic coil on the furnace surface, and the need for frequent shutdown of the automatic cooking machine for cooling or even damage.

[0088] At the same time, the furnace core for the automatic cooking machine provided by the present invention has a compact layout of the air inlet 51, the air inlet duct 271, the buffer air chamber 4 and the heat dissipation fan 8 therein, a pair of heater cavities 273, the air outlet duct 272 and the air outlet 61 constituting the air duct structure, and makes full use of the installation space on the outer side surface, the bottom end and the first flip axis 5 and the second flip axis 6 of the chamber wall 21 of the furnace 2 to arrange the air duct, thereby saving precious space inside the main unit of the automatic cooking machine for installing the air duct structure. At the same time, there is no need to set up a complex air duct and its sealing structure in the main unit, thereby simplifying the main unit structure of the automatic cooking machine.

[0089] Furthermore, since the heat dissipation air comes from the inner holes of the flip shafts on both sides of the furnace 2 (the first flip shaft 5 can be arranged on any one of the furnace 2), the colder air in the external environment is input into both sides of the furnace core and isolated from the heater cavity 273 in the middle which serves as the cooking area, the heat dissipation air is prevented from being disturbed by the cooking fumes in the pot 1 before contacting the heater coil 7, thereby ensuring the heat dissipation efficiency.

[0090] In addition, a buffer chamber (i.e., buffer air chamber 4) for heat dissipation gas is formed by utilizing the space enclosed between the air chamber bottom shell 26 (motor housing) and the chassis 22, which is connected to the heater cavity 273 accommodating the heater coil 7 and the air inlet duct 271. After the external cold air enters the air inlet duct 271, it first passes through the buffering and transition of the buffer air chamber 4 between the air chamber bottom shell 26 and the chassis 22, and then flows into a pair of heater cavities 273 from both sides of the furnace 2. This ensures that the heat dissipation gas continuously and circulates through the heater cavity 273 to always cool the heater coil 7, while achieving uniform heat dissipation of the heater coil 7 in the heater cavity 273 on both sides of the furnace 2, thereby ensuring that the heater coil 7 and the drive mechanism 31 (direct drive motor) can work stably for a long time.

[0091] Multiple cooling fans 8 arranged at one end of the heater cavity 273 on the outer side of the chamber wall 21 blow air toward the other end of the heater cavity 273, so that the cooling gas can flow through the heater cavity 273 along the outer surface of the chamber wall 21, thereby fully dissipating the heat of the heater coil 7 located in the heater cavity 273 and arranged on the outside of the chamber wall 21.

[0092] In summary, compared with the traditional automatic cooking machine, the air duct structure of the present invention uses a fan arranged in the main unit to blow air to the heater coil 7 from the periphery to improve the heat dissipation effect, thereby meeting the high-intensity use requirements of the commercial automatic cooking machine.

[0114] Please also read Figure 1-10 As a preferred implementation of this embodiment, the air duct housing 25 includes:

[0115] There are four arc-shaped cover plates 251, wherein a pair of the arc-shaped cover plates 251 are relatively arranged on both sides of the chamber wall frame 211, and the pair of arc-shaped cover plates 251 respectively cover and connect a pair of first air duct baffles 281 and a pair of second air duct baffles 282; wherein another pair of the arc-shaped cover plates 251 are relatively arranged on both sides of the chamber wall frame 211, and are staggered with the above-mentioned pair of arc-shaped cover plates 251, and respectively cover and connect adjacent first air duct baffles 281 and second air duct baffles 282.

[0122] Please also read Figure 1 , 2, 5-8, as a more preferred implementation mode of this embodiment, the area covered by the air inlet duct 271 and the air outlet duct 272 of the chamber wall frame 211 is smaller than the area covered by a pair of heater cavities 273 of the chamber wall frame 211, that is, the area of ​​one pair of arc-shaped cover plates 251 covering a pair of first air duct baffles 281 and a pair of second air duct baffles 282 is smaller than the area of ​​another pair of arc-shaped cover plates 251 covering adjacent first air duct baffles 281 and second air duct baffles 282, so that a pair of heater cavities 273 have enough space to accommodate a larger-sized heater coil 7, thereby improving the electromagnetic eddy current heating effect of the heater coil 7 on the pot inner body 1.

[0123] As other implementation modes of the present embodiment, a pair of first air duct partitions 281 and a pair of second air duct partitions 282 are asymmetrically arranged relative to each other at an angle less than 180 degrees, the air inlet duct 271 and the air outlet duct 272 are asymmetrically arranged relative to each other at an angle less than 180 degrees, and one of the pairs of arc cover plates 251 covering the pair of first air duct partitions 281 and the pair of second air duct partitions 282 are asymmetrically arranged relative to each other at an angle less than 180 degrees.

[0124] Please also read Figure 1-10 In this embodiment, the pot 1 is cylindrical and matches the shape of the chamber wall frame 211. One axial end of the pot 1 is an open chamber opening end 11, and the other axial end of the pot 1 is a closed chamber bottom end 12. The chamber bottom end 12 is rotatably connected to the bottom plate 22 at the bottom end of the chamber wall frame 211. The rotation axis direction of the pot 1 rotatably connected to the chamber wall frame 211 is parallel to and coincides with the axial direction of the pot 1 and the chamber wall frame 211.

[0125] That is, the furnace 2 can be turned up and down relative to the main unit of the automatic cooking machine through the chamber wall frame 211 with a first rotation axis X perpendicular to the axial direction of the chamber wall frame 211 (the first rotation axis X coincides with the first flip axis 5 and the second flip axis 6), and at the same time, the pot 1 can be rotated relative to the chamber wall frame 211 with a second rotation axis Y parallel to the axial direction of the chamber wall frame 211 (that is, perpendicular to the first rotation axis X direction) (the second rotation axis Y coincides with the axial direction of the pot 1 and the axial direction of the chamber wall frame 211 at the same time), so that the pot mouth end 11 of the rotating pot 1 can be switched to different orientations as the chamber wall frame 211 is turned up and down, such as flipping to the food feeding position, seasoning filling position, cooking position, dish serving position, pot washing position, etc.

[0126] At the same time, the furnace core of the automatic cooking machine provided by the present invention is provided with a pair of heater coils 7 on opposite sides of the chamber wall frame 211 of the furnace 2. When the furnace 2 is flipped to the point where the heater coils 7 on either side tilt downward, the corresponding heater coils 7 on the tilted side are powered on, while the heater coils 7 on the other side facing upward are not powered on. The furnace core of the automatic cooking machine always keeps the corresponding heater coils 7 on the side of the furnace 2 tilting downward powered on, thereby heating the downward-tilted part of the pot in the furnace 2 that receives the food for frying, while keeping the corresponding heater coils 7 on the upward side of the furnace 2 not powered on, to avoid the upward part of the pot in the furnace 2 that does not receive the food being heated by the corresponding other heater coil 7 and causing life loss.

[0127] Please also read Figure 1-10 As a preferred embodiment of this embodiment, an annular flange 111 is provided at the edge of the inner end 11 of the inner pot 1, and an annular inverted cone surface connected to the inner wall of the inner pot 1 is provided on the inner peripheral side of the annular flange 111, and an annular positive cone surface connected to the annular inverted cone surface is provided on the outer peripheral side of the annular flange 111. When the inner pot bottom end 12 is rotatably connected to the chamber wall frame 211, the annular flange 111 extends out of the chamber end 2111 and is spaced apart from the chamber end 2111.

[0128] Please also read Figure 1 , 5 -8. In this embodiment, the furnace core for the automatic cooking machine also includes:

[0129] The disc slip ring 9 is arranged at the rotation connection between the inner pot 1 and the bottom plate 22, and is used to connect the temperature sensor on the inner pot 1 with the temperature measuring control device outside the furnace core.

[0130] Please also read Figure 1 , 5 -8, as a preferred implementation of this embodiment, the disc slip ring 9 includes:

[0131] A plurality of temperature sensors 91 are evenly spaced and distributed on the circumference of the inner pot 1; a slip ring rotor 92 is arranged on the outer wall of the bottom end 12 of the inner pot 1; a plurality of groups of sliding electrodes 921, each group of sliding electrodes 921 is arc-shaped and evenly spaced and distributed on the slip ring rotor 92 along the circumference of the slip ring rotor 92 and electrically connected to the temperature sensors 91 one by one, each group of sliding electrodes 921 includes a plurality of sliding electrodes 921 spaced and distributed along the radial direction of the slip ring rotor 92, and the arc length of the sliding electrode 921 determines the circumferential area of ​​the inner pot 1 covered by the corresponding temperature sensor 91 connected thereto;

[0132] The slip ring stator 93 is arranged on the inner side of the chassis 22 facing the chamber wall skeleton 211; a plurality of groups of stator electrodes 931 are contact electrodes, each group of stator electrodes 931 is evenly spaced on the slip ring stator 93 along the circumference of the slip ring stator 93, and each group of stator electrodes 931 includes a plurality of stator electrodes 931 that are spaced along the radial direction of the slip ring stator 93 and match the sliding electrode 921, the positions of each group of stator electrodes 931 correspond to the positions of different circumferential regions of the pot 1, that is, the positions of each group of stator electrodes 931 depend on the measuring area of ​​the pot 1, and the stator electrodes 931 are electrically connected to the temperature measuring control device (not shown in the figure) on the main unit of the automatic cooking machine outside the furnace core.

[0133] When the inner pot 1 rotates, the slip ring rotor 92 is driven to rotate and connected to the slip ring stator 93, and the sliding electrode 921 can be in contact with the stator electrode 931 during the rotation process, so that when the inner pot 1 rotates until the sliding electrode 921 contacts the stator electrode 931, the temperature sensing signal generated by the temperature sensor 91 at the corresponding position of the inner pot 1 (i.e., on the area passing through the stator electrode 931) is electrically connected to the external temperature measurement control device of the furnace core through the stator electrode 931, thereby leading the temperature sensor signal to the outside of the furnace core, thereby realizing the real-time detection of the furnace core temperature by the automatic cooking machine.

[0134] Please also read Figure 1 , 5 -8, in this embodiment, the number of sliding electrodes 921 on the slip ring rotor 92 depends on the number of temperature sensors 91 on the inner pot 1, and the number of sensors 91 depends on the number of divisions of the measuring area of ​​the inner pot 1, that is, the measuring area that each sensor 91 is expected to cover. The number of stator electrodes 931 on the slip ring stator 93 does not need to be consistent with the number of sliding electrodes 921 on the slip ring rotor 92, and only one group needs to be set at the measuring position. When the sliding electrode 921 on the slip ring rotor 92 passes the stator electrode 931 on the slip ring stator 93, the corresponding temperature sensor 91 is connected, thereby greatly reducing the number of output electrodes and leads of the disc slip ring 9.

[0135] In another embodiment, the stator electrode 931 on the slip ring stator 303 is configured to be in an arc shape, and the sliding electrode 921 on the slip ring rotor 92 is configured to be a contact electrode, which has the same effect on signal transmission of the sensor 91 .

[0136] Please also read Figure 1 , 5 -8, as a better implementation of this embodiment, the disc slip ring 9 includes four groups of sliding electrodes 921 evenly distributed on the slip ring rotor 92 along the circumference of the slip ring rotor 92, and each group of sliding electrodes 921 includes four sliding electrodes 921 distributed along the radial direction of the slip ring rotor 92.

[0137] Please also read Figure 1 ,5 -8, as a better implementation method of this embodiment, the disc slip ring 9 includes two groups of stator electrodes 931 relatively arranged at both ends of the slip ring stator 93, and the two groups of stator electrodes 931 are respectively arranged at the corresponding bottom and upper part of the pot inner body 1, that is, at the 6 o'clock and 12 o'clock directions, that is, the measuring area of ​​the pot inner body 1 is the relative 6 o'clock and 12 o'clock direction areas, and each group of stator electrodes 931 includes four stator electrodes 931 distributed at radial intervals along the slip ring stator 93 and matching the sliding electrode 921.

[0138] Please also read Figure 1 , 5 -8, as a more preferred implementation of this embodiment, the slip-ring rotor 92 is provided with a plurality of (preferably four) concentric annular guide rails 922 at intervals, the slip-ring stator 93 is provided with a plurality of (preferably four) concentric annular guide grooves 932 that match the annular guide rails 922 at intervals, and each group of stator electrodes 931 is respectively arranged in the corresponding annular guide grooves 932, and the slip-ring rotor 92 is rotatably connected to the slip-ring stator 93 through the cooperation of the annular guide rails 922 and the annular guide grooves 932, so that the sliding electrode 921 is in contact and connected with the stator electrode 931 during the rotation process.

[0139] Please also read Figure 1 , 5 -8, as a better implementation of this embodiment, a pair of heater coils 7 are symmetrically arranged on the circumference of the chamber wall skeleton 211, and four temperature sensors 91 are evenly spaced around the circumference of the pot 1; the slip ring rotor 92 is in the shape of a ring, and four groups of sliding electrodes 921 (four in each group) are evenly spaced around the circumference of the slip ring rotor 92 and are electrically connected to the temperature sensors 91 one by one, and the arc length of the sliding electrodes 921 (four in each group) is close to one-fourth of the circumference length of the sliding electrode 921, such as reaching 0.22 to 0.24 of the circumference length of the sliding electrode 921, so that adjacent sliding electrodes 921 are arranged with a reduced spacing (angle); the slip ring stator 93 is in the shape of a ring that matches the shape of the slip ring rotor 92, and two groups (four in each group) of stator electrodes 931 are symmetrically arranged on the slip ring stator 93, and respectively match the positions of a pair of heater coils 7.

[0140] In other embodiments, six, eight or more temperature sensors 91 may be evenly distributed along the circumference of the pot 1. Correspondingly, six, eight or more groups of slip ring rotors 92 are evenly distributed along the circumference of the slip ring rotor 92 and are electrically connected one by one to the temperature sensors 91. The stator electrodes 931 are set in two groups and remain unchanged.

[0141] The stove core provided by the present invention adopts the connection layout of the above temperature sensor 91, the slip ring rotor 92 and its sliding electrode 921, the slip ring stator 93 and its stator electrode 931, which can realize the transmission of the temperature measurement signal of the temperature sensor 91 to the external temperature measurement control device during the rotation and frying of the pot 1, and realize the heat control of the automatic cooking machine by controlling the temperature of the pot 1. The heating temperature can be adjusted to highly imitate the heat control of the chef's cooking skills.

[0142] In addition, the multiple temperature sensors 91 corresponding to the multiple groups (such as four groups or two groups) of arc-shaped sliding electrodes 921 of the slip ring rotor 92 of the furnace core only need to be transmitted to the external temperature measurement control device periodically and in pairs through the two groups of cables of the two groups of point-shaped stator electrodes 931 of the slip ring stator 93, thereby avoiding the cable entanglement problem that the temperature sensor 91 on the pot body 1 is connected to the external temperature measurement control device using traditional cables. At the same time, the multiple groups of arc-shaped sliding electrodes 921 connected to the multiple groups (such as four groups or two groups) of temperature sensors 91 only need to transmit signals to the external temperature measurement control device through two groups of point-shaped stator electrodes 931 and their two groups of cables, without the need to set up multiple groups (such as four groups or two groups) of point-shaped stator electrodes 931 and multiple groups of cables to transmit signals, thereby avoiding the complication of the furnace core structure, the increase of manufacturing costs and the reduction of electromagnetic compatibility due to the excessive number of stator electrodes 931 and their lead-out cables.

[0143] In this embodiment, the point-shaped stator electrode 931 is arranged at the bottom and the arc-shaped sliding electrode 921 is arranged at the top. The point-shaped stator electrode 931 (contact electrode) with a smaller area and a larger interval between adjacent electrodes is arranged at the bottom to reduce the probability of foreign matter or water stains adhering to the electrode, and reduce the detection failure rate caused by the adhesion of foreign matter, water stains or the connection of foreign matter and water stains to adjacent electrodes; at the same time, avoid arranging the arc-shaped sliding electrode 921 with a larger area at the bottom, which makes it easy for foreign matter and water stains to adhere to the electrode and connect to adjacent electrodes due to foreign matter and water stains.

[0144] In other embodiments, four groups of stator electrodes 931 and their lead cables may be provided, and the four groups of stator electrodes 931 are evenly spaced and distributed on the slip ring stator 93 along the circumference of the slip ring stator 93 (two groups of stator electrodes 931 are cross-arranged), that is, each group of stator electrodes 931 covers a 90-degree area in the circumference of the pot 1. Since the stator electrodes 931 are provided in four groups, two groups of stator electrodes 931 are added as redundant designs relative to only two groups. When two groups of stator electrodes 931 fail, the other two groups of stator electrodes 931 can be switched to use, so as to avoid the disc slip ring 9 being unable to work due to the failure of the stator electrodes 931 when only two groups of stator electrodes 931 are provided.

[0145] Alternatively, the four groups of stator electrodes 931 may directly and synchronously contact and detect the temperature sensors 91 connected to the four groups of sliding electrodes 921.
