Description

Technical Field

[0001] This invention relates to the field of electric stove technology, specifically to a modular structure for a plasma electric stove system. Background Technology

[0002] An electric stove is a new type of stove that uses the phenomenon of electric arc discharge to generate a flame by ionizing the air, thus achieving open-flame cooking. Compared with traditional gas stoves, electric stoves change the traditional combustion method, fundamentally avoiding accidents such as gas leaks and gas explosions, and have the advantages of being safer and more convenient. In recent years, they have been increasingly used in both household and commercial cooking.

[0003] However, existing electric stoves typically use a single circuit board to connect multiple burners to heat cookware, employing a centralized control method. This centralized control method has the following drawbacks: if any burner malfunctions or the circuit fails, the protection circuit will shut down the entire unit, rendering the stove unusable. Users are forced to stop cooking and wait for after-sales repairs, which is extremely inconvenient.

[0004] Therefore, it is necessary to provide an electric stove structure that is modular in structure and capable of fault isolation in order to overcome the above-mentioned defects. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide a modular structure for a plasma electric stove system, which has the advantages of being easy to use, safe and reliable, easy to maintain, and having uniform and controllable temperature.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A modular structure for a plasma electric stove system includes a stove body, wherein a combustion chamber is provided inside the stove body, and multiple burners are provided inside the combustion chamber; The stove body has multiple plasma generator modules built in, and each of the multiple plasma generator modules has an independent protection circuit. The power supply terminals of the multiple plasma generator modules are connected to each other in parallel, and the discharge terminals of the multiple plasma generator modules are respectively connected to the multiple burners, and the burners connected to different plasma generator modules are different. The multiple burners are arranged in an array with the center line of the combustion chamber as the center, forming multiple annular combustion rings spaced apart radially. Multiple burners connected to the same plasma generator module are evenly spaced apart from each other in the same annular combustion ring, so that the multiple annular combustion rings have different heating powers.

[0007] Furthermore, the plasma generator module includes a boost circuit, the protection circuit, and a boost transformer assembly; The boost circuit and the protection circuit are integrated on the same circuit board to form a boost protection circuit board, which is electrically connected to the boost transformer assembly via connectors.

[0008] Furthermore, the protection circuit includes a detection unit and a switching unit; The switching unit is connected in series in the power supply branch of the corresponding plasma generator module, and the detection terminal of the detection unit is connected to the input terminal of the step-up transformer assembly to detect at least one of the current and voltage of the input terminal. The output terminal of the detection unit is connected to the control terminal of the switch unit to control the switch unit to disconnect the corresponding power supply branch when the detection value exceeds the set range.

[0009] Furthermore, the output terminal of the detection unit is connected to the control terminal of the switching unit. When at least one of the multiple burners connected to the corresponding plasma generator module experiences a discharge abnormality, causing the detected value of at least one of the current and voltage at the input terminal of the step-up transformer assembly to exceed the set range, the detection unit controls the switching unit to disconnect the power supply branch of the corresponding plasma generator module. By monitoring the electrical parameters at the input terminal of the step-up transformer assembly in real time, the system can accurately identify the discharge abnormality. Once a deviation of the current or voltage from the preset safety value is detected, the detection unit immediately sends a control signal to the switching unit to quickly cut off the corresponding power supply branch. This mechanism not only effectively reduces the overall system paralysis caused by local faults but also reduces the damage to core components caused by overload, thereby improving the safety and reliability of the plasma stove operation and extending the service life of the equipment.

[0010] Furthermore, the step-up transformer assembly is a step-up transformer module, which includes at least two stacked combined step-up transformers; The combined step-up transformer includes a magnetic core, a primary winding wound on the magnetic core, and two secondary windings wound on the magnetic core. The primary windings of at least two of the combined step-up transformers are connected in series and then connected to the step-up protection circuit board. Each of the secondary windings forms a high-voltage output and is connected to a corresponding spark plug.

[0011] Furthermore, the output terminal of the step-up transformer assembly is electrically connected to the corresponding burner head through a heat-insulating, high-conductivity transition component; The thermally insulating and highly conductive transition component includes a conductive substrate and a heat-insulating sleeve covering the outer periphery of the conductive substrate. One end of the conductive substrate is connected to the output end of the step-up transformer assembly, and the other end is connected to the burner. The burner includes a high-temperature resistant metal body, an insulating base disposed within the high-temperature resistant metal body, and at least two tungsten alloy electrodes.

[0012] Furthermore, at least two of the tungsten alloy electrodes are insulated from each other and fixed to the insulating base at intervals, with a discharge gap formed between the tips of two adjacent tungsten alloy electrodes.

[0013] Furthermore, the stove body is provided with multiple installation stations and power supply busbars, and multiple plasma generator modules are respectively installed in multiple installation stations; Each of the installation stations is equipped with a power connector, which is pluggable to the power supply terminal of the plasma generator module installed in the corresponding installation station. Multiple plasma generator modules are connected in parallel to the power supply bus via corresponding power connectors.

[0014] Furthermore, each of the installation stations is provided with a guide rail, and the plasma generator module can be pulled out and installed in the corresponding installation station via the guide rail; a positioning structure is provided between the installation station and the plasma generator module, and the positioning structure is used to connect the power supply terminal with the power connector when the plasma generator module is inserted into place.

[0015] Furthermore, the burners connected to different plasma generator modules are alternately arranged in the same annular combustion ring; among the multiple annular combustion rings, the number of burners in the inner annular combustion rings is less than the number of burners in the outer annular combustion rings.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention employs multiple plasma generator modules, each with its own independent protection circuit, and connects these modules in parallel to the power supply circuit. Each protection circuit controls only the power supply branch of its corresponding module. When any module or its connected burner malfunctions, only the corresponding power supply branch is disconnected, without affecting the continued operation of the remaining modules and burners, thereby achieving fault isolation and reducing downtime of the entire machine.

[0017] 2. The burner of this invention forms multiple radially spaced annular combustion rings; within each annular combustion ring, the burners corresponding to the same module are evenly spaced circumferentially, and the burners corresponding to different modules are alternately arranged, with the burners corresponding to each module distributed across at least two annular combustion rings. Therefore, when any module is turned off, its corresponding vacancy can be dispersed in both the circumferential and radial directions, and the pot body can still maintain a relatively uniform heating state.

[0018] 3. Each plasma generator module of the present invention is connected in parallel to the power supply bus via a power connector and can be pulled out and installed in the installation position of the stove body via a guide rail. This allows for independent disassembly, repair and replacement of individual modules, making maintenance convenient and eliminating the need to disassemble the entire machine.

[0019] 4. The step-up transformer assembly of the present invention adopts a step-up transformer module composed of at least two combined step-up transformers stacked together. Each combined step-up transformer has a primary winding and two secondary windings on the same magnetic core. The primary windings are connected in series in sequence, so that the structure is compact and can form multiple high-voltage outputs to drive multiple burners respectively.

[0020] 5. The present invention provides a heat-insulating, high-conductivity transition component between the step-up transformer assembly and the discharge head, and provides an insulating base within the high-temperature resistant metal body, so that at least two tungsten alloy electrodes are fixed insulated from each other and form a discharge gap, thereby taking into account high voltage transmission, thermal isolation, high temperature resistance and discharge stability.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. It should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0024] Please see Figures 1 to 6This embodiment provides a modular structure for a plasma cooker system, including a cooker body 1. The cooker body 1 contains a combustion chamber 2 for accommodating the plasma arc flame and heating the pot. The cooker body 1 contains multiple plasma generator modules 10. This embodiment uses three plasma generator modules 10 as an example, but the number of modules is not limited to three; it can be set to two, three, or more depending on the cooker's power and the number of burners. Each plasma generator module 10 has an independent protection circuit 12, and each protection circuit 12 is independent of each other and only controls the power supply branch of the corresponding module.

[0025] like Figure 1 As shown, the power supply terminals 16 of multiple plasma generator modules 10 are connected in parallel to the same power supply circuit; the discharge terminal 17 of each plasma generator module 10 is connected to multiple burners 22 disposed in the combustion chamber 2, and the burners 22 connected to different modules do not overlap. Thus, each module can independently draw power and drive its corresponding burner 22, and when the power supply branch of any module is disconnected, the power supply branches of the other modules remain connected.

[0026] like Figure 2 As shown, all the burners 22 connected to the multiple plasma generator modules 10 are arranged in an array with the center line 3 of the combustion chamber 2 as the center, forming multiple annular combustion rings 4 spaced radially apart. This embodiment has three annular combustion rings 4: an inner ring, a middle ring, and an outer ring. The burners 22 connected to each module are distributed in at least two annular combustion rings 4. Within each annular combustion ring 4, the burners 22 connected to the same module are evenly spaced circumferentially, while the burners 22 connected to different modules are alternately arranged circumferentially. The number of burners 22 in the inner ring is less than the number in the outer ring, to accommodate different circumferential lengths and improve overall heating distribution. When any module is turned off, the gaps formed by its corresponding burners 22 are dispersed in the circumferential and radial directions, and the pot body can still maintain a relatively uniform heating state.

[0027] Please see Figure 6 Each plasma generator module 10 includes a boost circuit 11, a protection circuit 12, and a boost transformer assembly 15. The boost circuit 11 and the protection circuit 12 are integrated on the same circuit board to form a boost protection circuit board 13; the boost protection circuit board 13 is electrically connected to the boost transformer assembly 15 via a connector 14. The connector 14 is a pluggable connector to facilitate the assembly, disassembly, and replacement of the boost transformer assembly 15 and the boost protection circuit board 13.

[0028] Continue reading Figure 6The protection circuit 12 includes a detection unit 121 and a switching unit 122. The switching unit 122 is connected in series in the power supply branch of the plasma generator module 10 to cut off the power supply to the group when needed. The detection terminal of the detection unit 121 is connected to the input terminal of the step-up transformer assembly 15 of the group to detect the current, voltage and other operating parameters of the group. The output terminal of the detection unit 121 is connected to the control terminal of the switching unit 122. Furthermore, when the discharge of the burner 22 of the group is abnormal, such as arc failure, short circuit or overcurrent, the current, voltage and other operating parameters of the input terminal of the step-up transformer assembly 15 of the group change and are transmitted to the detection unit 121. The detection unit 121 disconnects the power supply branch of the plasma generator module 10 of the group through the switching unit 122, thereby isolating the group, while the other groups are not affected.

[0029] In one optional embodiment, the output terminal of the detection unit 121 is connected to the control terminal of the switch unit 122; when at least one of the plurality of burners 22 connected to the corresponding plasma generator module 10 experiences a discharge abnormality, causing the detection value of at least one of the current and voltage at the input terminal of the step-up transformer assembly 15 to exceed the set range, the detection unit 121 controls the switch unit 122 to disconnect the power supply branch of the corresponding plasma generator module 10.

[0030] like Figure 4 As shown, the step-up transformer assembly 15 in this embodiment is a step-up transformer module. The step-up transformer module includes at least two stacked combined step-up transformers 151. Figure 4 Taking two combined step-up transformers 151 as an example, each combined step-up transformer 151 includes a magnetic core 154, a primary winding 152 wound on the magnetic core 154, and two secondary windings 153. The primary windings 152 of each combined step-up transformer 151 are connected in series and then connected to the step-up protection circuit board 13. Each secondary winding 153 constitutes a high-voltage output and is connected to a corresponding burner 22, thus forming multiple high-voltage outputs from one step-up transformer module.

[0031] Please see Figure 5The output terminal 17 of the step-up transformer assembly 15, i.e., the discharge terminal 17, is electrically connected to the burner 22 via a heat-insulating, high-conductivity transition component 23. The heat-insulating, high-conductivity transition component 23 includes a conductive substrate 231 and a heat-insulating sleeve 232 covering the outer periphery of the conductive substrate 231. One end of the conductive substrate 231 is connected to the output terminal of the step-up transformer assembly 15, and the other end is connected to the burner 22, thereby reducing the heat conduction from the burner 22 to the step-up transformer assembly 15 while transmitting high voltage. The burner 22 includes a high-temperature resistant metal body 221, an insulating base 223 disposed within the high-temperature resistant metal body 221, and at least two tungsten alloy electrodes 222. The at least two tungsten alloy electrodes 222 are insulated from each other and fixed at intervals on the insulating base 223, with a discharge gap 224 formed between the tips of adjacent tungsten alloy electrodes 222. One high-voltage output of the step-up transformer assembly 15 is applied between two tungsten alloy electrodes 222 that form the same discharge gap 224, causing breakdown and ionization of the air at the discharge gap 224 to form a plasma arc flame. Figure 5 This is a schematic diagram of one of the thermal insulation and conductive connections.

[0032] Please see Figure 3 The stove body 1 has multiple installation stations 18 for installing multiple plasma generator modules 10. Each installation station 18 has a power connector 19 that can be plugged into and connected to the power supply terminal 16 of the corresponding module. The multiple plasma generator modules 10 are connected in parallel to the power supply bus 9 located in the stove body 1 via the corresponding power connector 19. Each installation station 18 has a guide rail 20, and the plasma generator module 10 can be pulled out and installed in the corresponding installation station 18 via the guide rail 20 for independent insertion or removal. A positioning structure 21 is provided between the installation station 18 and the plasma generator module 10. The positioning structure 21 ensures accurate connection and conduction between the power supply terminal 16 and the power connector 19 when the module is inserted into place. The stove body 1 includes a heat insulation shell 5 located around the combustion chamber 2. The multiple plasma generator modules 10 are located inside the heat insulation shell 5, and the heat insulation shell 5 also has heat dissipation ducts 6 corresponding to the multiple modules.

[0033] like Figure 1 As shown, this embodiment also includes a power switch 7 and a power control unit 8. The power switch 7 is connected in series in the power supply circuit that supplies power to the multiple plasma generator modules 10, and is used to control the on / off state of the entire unit; the power control unit 8 is connected to the multiple plasma generator modules 10 respectively, and is used to adjust the output power of each module. The external power supply can be 110V, 220V or 380V AC power, and is distributed to each parallel plasma generator module 10 via the power switch 7 and the power supply bus 9.

[0034] The working principle of this embodiment is as follows: An external power supply is connected via a power switch 7 and distributed by a power supply bus 9 to multiple parallel plasma generator modules 10. Within each module, a boost circuit 11 transforms the input power and drives a boost transformer assembly 15. The high-voltage outputs generated by the boost transformer assembly 15 are applied between the tungsten alloy electrodes 222 of the corresponding burner 22 via corresponding connection lines, ionizing the air at the discharge gap 224 to form a plasma arc flame, which heats the pot body above the combustion chamber 2. The power control unit 8 can adjust the output power of each module separately. When a group of plasma generator modules 10 or its burner 22 malfunctions, the detection unit 121 of that group detects the abnormality through the boost transformer assembly 15 and controls the switch unit 122 to disconnect only the corresponding power supply branch; the remaining modules continue to operate normally. Since the burners 22 corresponding to each module are evenly spaced and alternately arranged within each annular combustion ring 4 and distributed in at least two annular combustion rings 4, the gaps corresponding to the closed modules are dispersed in the circumferential and radial directions, and the pot body is still heated relatively uniformly.

[0035] As an example, a configuration of three plasma generator modules 10, three annular combustion rings 4, and a total of twenty-four burners 22 can be used. Each module's burners 22 are distributed across at least two annular combustion rings 4. When any of the first, second, or third modules is damaged or manually shut down, only the burners 22 connected to that module extinguish, while the remaining burners 22 continue to ignite normally. This ensures continuous and relatively uniform heating of the pot while achieving unit-based isolation of the fault. The number of plasma generator modules 10, the number of annular combustion rings 4, and the number and arrangement of burners 22 can be adjusted according to actual power and pot diameter requirements.

[0036] Please see Figure 7 and Figure 8 This further illustrates the modular connection relationship of multiple plasma generator modules 10. For example... Figure 7 As shown, an external 110V, 220V or 380V AC power supply is connected to the power supply bus 9 via the power switch 7, and is distributed by the power supply bus 9 to two parallel plasma generator modules 10; each module includes a boost circuit 11, a protection circuit 12 and a boost transformer assembly 15, and the protection circuit 12 only controls the power supply branch of the corresponding module. Figure 8 The diagram shows an expansion to N plasma generator modules 10, each with the same structure and connected in parallel to the power supply bus 9, thus allowing the number of modules to be expanded according to the power requirements of the electric stove.

[0037] Please see Figures 9 to 11 It shows the working status of each flame head 22 when any of the three plasma generator modules 10 is damaged or manually shut down, where the mark with the flame diagram indicates the flame head 22 that is firing normally, and the mark without flame indicates the flame head 22 that is extinguished. Figure 9 , Figure 10 and Figure 11 The diagram shows the states where the first, second, and third modules are turned off. In each state, only the burner 22 connected to the corresponding module is extinguished, while the burners 22 connected to the other modules continue to ignite normally. Since the burners 22 corresponding to the same module are evenly spaced circumferentially, and the burners 22 corresponding to different modules are alternately arranged circumferentially, and the burners 22 corresponding to each module are distributed in at least two annular combustion rings 4, the gaps formed by the extinguished burners 22 after any module is turned off are distributed in both the circumferential and radial directions.
