Description

Technical Field

[0001] This utility model relates to the field of intelligent cooking equipment technology, and specifically to a heating device applied to intelligent cooking equipment. Background Technology

[0002] To improve meal preparation efficiency, a smart cooking device with multiple cooking stations has emerged on the market. It can intelligently and automatically control the heating of the lunch box to cook the ingredients inside according to the set program. The smart cooking device can refer to the technical solution of application number 202210411435.X.

[0003] The heating device is the core component of intelligent cooking equipment for achieving efficient food preparation, and its performance directly affects cooking efficiency and food quality. For example, the electromagnetic heating device disclosed in application number CN202320979666.0 uses a magnetic core and coil outside the heating chamber to heat the food container using the principle of electromagnetic induction, offering the advantage of high thermal efficiency.

[0004] However, in this technical solution, the heating chamber is composed of an upper chamber and a lower chamber that cover each other. In this configuration, the annular part of the heating chamber is also made up of two half-rings. There is a gap between the annular part of the heating chamber and the outer circumference of the roller. This gap is prone to friction with the roller, which accelerates the wear of the roller during operation. Long-term friction can easily lead to a decrease in the rotational quality of the heating chamber. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a heating device for use in intelligent cooking equipment.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A heating device for use in intelligent cooking equipment includes a heating chamber, an electromagnetic coil, and a driving device. The electromagnetic coil is mounted on the heating chamber, and the rotational output end of the driving device is connected to the heating chamber via a transmission connection. The heating chamber is composed of a first half-shell and a second half-shell joined together. The device is characterized by further including a mounting ring. The outer circumferential surface of the mounting ring is a circular circumferential surface for contacting an auxiliary roller. The inner ring of the mounting ring has a turntable insertion hole and a turntable through hole coaxially arranged with the mounting ring. The front end of the first half-shell has a first arcuate protrusion, and the front end of the second half-shell has a second arcuate protrusion. The first arcuate protrusion and the second arcuate protrusion combine to form a mating ring that fits into the turntable insertion hole. Both the first half-shell and the second half-shell are fixedly connected to the mounting ring.

[0007] In this invention, a circular stop surface is provided between the turntable insertion hole and the turntable through hole. When the mating ring is inserted into the turntable insertion hole and its front end abuts against the circular stop surface, the mating ring cannot continue to be inserted in the direction of penetrating the turntable insertion hole.

[0008] In this utility model, a first half-shaft is integrally formed at one end of the first half-shell, and a second half-shaft is integrally formed at one end of the second half-shell. The first half-shaft and the second half-shaft are joined together to form an installation shaft.

[0009] In this invention, the inner cavity of the first half-shell and the inner cavity of the second half-shell form a heating cavity for placing a lunchbox, and the heating cavity is provided with a heat insulation panel.

[0010] In this utility model, both the inner cavities of the first half-shell and the second half-shell are provided with microcrystalline mounting surfaces. The microcrystalline mounting surfaces on the first half-shell and the second half-shell are arranged opposite to each other. The microcrystalline mounting surfaces are provided with panel mounting grooves for embedding heat insulation panels.

[0011] In this invention, both the outer surfaces of the first half-shell and the second half-shell are provided with coil winding grooves, and the electromagnetic coil is wound inside the coil winding grooves.

[0012] In this invention, a magnetic block module is provided on the outer wall of the heating chamber.

[0013] In this invention, the magnetic block module includes a first magnetic block group and a second magnetic block group. The first magnetic block group includes a first magnetic block base and a plurality of first permanent magnets. The first magnetic block base is provided with a plurality of first magnetic block slots, and at least one first permanent magnet is embedded in each first magnetic block slot. The second magnetic block group includes a second magnetic block base and a plurality of second permanent magnets. The second magnetic block base is provided with a plurality of second magnetic block slots, and at least one second permanent magnet is embedded in each second magnetic block slot. Both the first magnetic block base and the second magnetic block base are fixed to the outer wall of the heating chamber.

[0014] In this invention, the driving device includes a drive motor and a transmission assembly. The drive motor is mounted on the heating mounting bracket via a motor mount, and the output shaft of the drive motor is connected to the mounting shaft of the heating chamber via the transmission assembly.

[0015] In this invention, one end of the mounting ring extends out of the housing through the heating window, and the outer periphery of the mounting ring is provided with a shielding protrusion for blocking the heating window to prevent foreign objects from entering the housing.

[0016] The beneficial effects of this utility model are as follows: This utility model features an independent mounting ring that contacts the auxiliary roller, replacing the traditional heating chamber splicing ring which bears the force. This avoids friction between the splicing gap and the auxiliary roller, reducing wear on the auxiliary roller and thus improving the rotational stability of the heating chamber and extending the life of the auxiliary roller. Furthermore, the microcrystalline heat-insulating panel inside the heating chamber prevents damage to the heating chamber from the high temperature of the food container, improving the stability of the heating device. The electromagnetic coil, in conjunction with the magnetic block module, enhances inductance, reduces magnetic leakage, and improves heating uniformity and efficiency. Attached Figure Description

[0022] Reference Figure 1-6 A heating device for use in intelligent cooking equipment includes a heating chamber for holding a lunchbox, an electromagnetic coil for heating the lunchbox, and a drive device for rotating the heating chamber. The heating chamber is rotatably disposed within a housing 100. The electromagnetic coil is mounted on the heating chamber, and the rotational output end of the drive device is connected to the heating chamber via a transmission connection. The heating chamber is composed of a first half-shell 1 and a second half-shell 2 joined together by bolts. The inner cavities of the first half-shell 1 and the second half-shell 2 form the heating chamber for holding the lunchbox.

[0023] Furthermore, the heating device also includes a mounting ring 3, the outer circumferential surface of which is a circular circumferential surface 31 for contacting the auxiliary roller 300. The inner ring of the mounting ring 3 is provided with a turntable insertion hole 32 and a turntable through hole 33 coaxially arranged with the mounting ring 3. A circular stop surface 34 is provided between the turntable insertion hole 32 and the turntable through hole 33. The front end of the first half-shell 1 is integrally formed with a first arc protrusion 11, and the front end of the second half-shell 2 is integrally formed with a second arc protrusion 21. The first arc protrusion 11 and the second arc protrusion 21 are... The protrusions 21 combine to form a mating ring that fits into the turntable insertion hole 32. When the mating ring is inserted into the turntable insertion hole 32 and its front end abuts against the ring stop surface 34, the mating ring cannot continue to be inserted further into the turntable insertion hole 32. At this time, the outer wall of the mating ring contacts the hole wall of the turntable insertion hole 32, and the turntable through hole 33 is directly opposite the inner ring of the mating ring. Then, the first half-shell 1 and the second half-shell 2 are both fixedly connected to the mounting ring 3 by bolts, thereby realizing the synchronous rotation of the heating chamber and the mounting ring 3. Moreover, by having the mounting ring 3 contact the auxiliary roller 300, the frictional wear of the heating device on the auxiliary roller 300 can be reduced, which not only improves the stability of the rotation of the heating chamber, but also effectively extends the service life of the auxiliary roller 300.

[0024] Furthermore, a first half-shaft 12 is integrally formed at one end of the first half-shell 1, and a second half-shaft 22 is integrally formed at one end of the second half-shell 2. The first half-shaft 12 and the second half-shaft 22 are joined together to form a mounting shaft. A mounting bearing seat 4 for mounting on the heating mounting bracket 200 is fitted on the mounting shaft, thereby realizing the rotational installation of the heating chamber. At the same time, the connection quality of the first half-shell 1 and the second half-shell 2 is more stable and reliable under the constraint of the mounting bearing seat 4 and the mounting ring 3, effectively avoiding loosening during operation.

[0025] When the heating device is installed on the housing 100 of the intelligent cooking equipment, each heating device corresponds to a heating station on the housing 100. The housing 100 is provided with a heating mounting bracket 200. The housing 100 is provided with a roller assembly corresponding to the mounting ring 3. The roller assembly includes a roller bracket fixed on the housing 100 and multiple auxiliary rollers 300 rotatably mounted on the roller bracket. The roller surface of the auxiliary rollers 300 rolls in contact with the outer circumferential surface of the mounting ring 3 and supports the mounting ring 3, thereby achieving the purpose of rotatably setting the heating chamber inside the housing 100.

[0026] In this embodiment, a heat insulation panel 5 is provided inside the heating chamber. The heat insulation panel 5 is preferably a microcrystalline panel. The heat insulation panel 5 can provide a certain degree of insulation between the food container and the heating chamber, preventing excessive heat from the food container from damaging the internal structure of the heating chamber. Furthermore, both the first half-shell 1 and the second half-shell 2 have microcrystalline mounting surfaces inside their respective cavities. The microcrystalline mounting surfaces on the first half-shell 1 and the second half-shell 2 are positioned opposite each other, and the microcrystalline mounting surfaces are provided with panel mounting grooves for embedding the heat insulation panel 5.

[0027] In this embodiment, a temperature sensor 6 is provided on the heating chamber to monitor the temperature changes inside the heating chamber in real time and feed the temperature data back to the control module of the intelligent cooking device, thereby improving the control accuracy of the heating device and ensuring the heating quality of the food container to be heated by each heating device.

[0028] In this embodiment, both the first half-shell 1 and the second half-shell 2 are provided with coil winding grooves on their exteriors. The electromagnetic coil is wound inside the coil winding grooves and electrically connected to the control module. When the electromagnetic coil is energized, it generates electromagnetic induction, thereby achieving uniform heating of the lunchbox inside the heating cavity. The electromagnetic coil is not shown in the accompanying drawings.

[0029] In this embodiment, a magnetic block module is provided on the outer wall of the heating chamber. The magnetic block module can be used in conjunction with the electromagnetic coil to increase inductance, reduce magnetic leakage, and improve heating uniformity and efficiency. Furthermore, the magnetic block module includes a first magnetic block group 7 and a second magnetic block group 8 respectively installed on different sides of the outer wall of the heating chamber. The area covered by the first magnetic block group 7 on the outer wall of the heating chamber is larger than the area covered by the second magnetic block group 8. The second magnetic block group 8 has a smaller coverage area and is mainly used to supplement the electromagnetic field distribution, ensuring that the magnetic lines of force in the heating area are denser and more uniform. The first magnetic block group 7 includes a first magnetic block seat 71 and a plurality of first permanent magnets 72. The first magnetic block seat 71 is provided with a plurality of first magnetic block slots, and at least one first permanent magnet 72 is embedded in each first magnetic block slot. The second magnetic block group 8 includes a second magnetic block seat 81 and a plurality of second permanent magnets 82. The second magnetic block seat 81 is provided with a plurality of second magnetic block slots, and at least one second permanent magnet 82 is embedded in each second magnetic block slot. The first magnetic block seat 71 and the second magnetic block seat 81 are both fixed to the outer wall of the heating chamber by bolt connection. The first permanent magnets 72 and the second permanent magnets 82 are respectively installed on the first magnetic block seat 71 and the second magnetic block seat 81, so that the first permanent magnets 72 and the second permanent magnets 82 are separated from the electromagnetic coil, avoiding direct contact that could cause the magnets to demagnetize due to high temperature or structural damage.

[0030] In this embodiment, the driving device includes a drive motor 91 and a transmission assembly. The drive motor 91 is mounted on the heating mounting bracket 200 via a motor mount 92. The output shaft of the drive motor 91 is connected to the mounting shaft of the heating chamber via the transmission assembly to drive the heating chamber to rotate around its axis. The drive motor 91 starts and stops under the command of the control module, and transmits power to the mounting shaft through the transmission assembly, so that the heating chamber rotates smoothly under the support of the mounting bearing seat 4 and the roller assembly, thereby ensuring that the food container inside the heating chamber is heated evenly.

[0031] In this embodiment, the transmission assembly includes a drive pulley 93 mounted on the output shaft of the drive motor 91, a driven pulley 94 fixed on the mounting shaft, and a synchronous belt 95 that drives the drive pulley 93 and the driven pulley 94. The synchronous belt 95 efficiently transmits the power of the drive motor 91 to the mounting shaft, thereby achieving stable rotation of the heating chamber.

[0032] In this embodiment, a positioning turntable 96 is installed on the driven pulley 94. The positioning turntable 96 rotates synchronously and coaxially with the driven pulley 94. A positioning detection switch 97 is correspondingly matched with the positioning turntable 96. The positioning detection switch 97 is located inside the housing 100 and installed on the heating mounting bracket 200. It is used to detect the rotation angle of the positioning turntable 96 in real time. When the positioning turntable 96 rotates to the preset position, the positioning detection switch 97 outputs a signal to the control module. The control module determines the current working status of the heating chamber based on this signal and accurately controls the drive motor 91 to stop, ensuring that the stopping position of the heating chamber is accurate and consistent after each rotation.

[0033] In this embodiment, the positioning detection switch 97 is preferably a photoelectric switch, with its transmitting and receiving ends facing each other. The edge of the positioning turntable 96 has a blocking part. When the blocking part passes the photoelectric switch, a pulse signal is generated, allowing the control module to know whether the heating chamber has returned to the set position. Simultaneously, a trigger block 951 is provided on the synchronous belt 95, and a limit switch 98 corresponding to the position of the trigger block 951 is provided inside the housing 100. The limit switch 98 is mounted on the motor base 92. When the heating chamber rotates to a specified angle, the trigger block 951 touches the pressing end of the limit switch 98 and sends a signal to the control module. This assists in realizing position verification and safety protection during the rotation of the heating chamber, avoiding positioning deviations caused by abnormal signals from the positioning turntable 96, and further improving the stability and reliability of the intelligent cooking equipment.

[0034] In this embodiment, one end of the mounting ring 3 extends out of the housing 100 through the heating window. The outer periphery of the mounting ring 3 has a raised shielding ring 35 to block the heating window and prevent foreign objects from entering the housing 100. Furthermore, the diameter of the shielding ring 35 is larger than the opening size of the heating window, so that the shielding ring 35 always covers the edge of the heating window during the rotation of the mounting ring 3, effectively preventing dust, oil, and other foreign objects from entering the housing 100 and reducing contamination inside the housing 100.

[0035] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
