Description

Technical Field

[0001] This utility model relates to the field of kitchenware technology, and in particular to an electric flame zoned electric flame stove. Background Technology

[0002] An electric flame stove, as the name suggests, is a type of open-flame stove that does not use chemical fuels; it can also be described as a device that ignites air. At first glance, an electric flame stove looks just like a gas stove commonly used in households, both using flames to heat food. The difference is that a gas stove requires natural gas or liquefied petroleum gas (LPG). Without these gases, a gas stove cannot function. Furthermore, the gas used in gas stoves is a hazardous material; leaks can easily lead to explosions, which can be extremely dangerous.

[0003] Therefore, electric flame stoves have emerged. They are highly safe to use, and users do not need to worry about the risks of gas explosions. However, since they have only been developed in recent years, their production time is short, and their cost is much higher than that of gas stoves. Therefore, their popularity is still not very high. But with the development of technology, their cost will inevitably decrease, making them widely used in the future.

[0004] For existing electric flame stoves on the market, the burner head is basically a single unit. When the burner head breaks down, the entire burner head needs to be replaced for maintenance. At this time, it cannot continue to work until it is replaced, resulting in interruption of use. It has poor adaptability and cannot meet temporary emergency needs, and its service life is short.

[0005] The existing problems need to be addressed. Utility Model Content

[0006] This utility model aims to at least partially solve one of the technical problems in related technologies. Therefore, the purpose of this utility model is to propose an electric flame zoned electric flame stove.

[0007] To achieve one of the above objectives, according to an embodiment of the present utility model, an electric flame partitioned electric flame stove includes a stove body, an electric flame generating device inside the stove body, an outer ring burner, an inner ring burner, a first rotary switch for adjusting the size of the outer ring electric flame and controlling the outer ring electric flame to emerge from the outer ring burner, and a second rotary switch for adjusting the size of the inner ring electric flame and controlling the inner ring electric flame to emerge from the inner ring burner.

[0008] The upper surface of the stove body has an installation port; the outer ring burner is formed into a ring structure, and its outer periphery is detachably snapped into the installation port; the inner ring burner is detachably snapped into the outer ring burner; the first rotary switch and the second rotary switch are both connected to the electric flame generating device.

[0009] In addition, the electric flame partitioned electric flame stove according to the above embodiments of this utility model may also have the following additional technical features:

[0010] According to one embodiment of the present invention, the outer ring burner head includes a fixing ring, an outer burner body, and a pot ring with both the upper and lower ends formed as open to support cooking utensils;

[0011] The outer diameter of the fixing ring is slightly larger than the inner diameter of the mounting opening, so that its outer periphery can be adapted to be supported by the inner edge of the mounting opening, and the middle part of the fixing ring is recessed downward to form a ring-shaped recessed portion that fits and is locked into the mounting opening.

[0012] The outer furnace body is a hollow ring structure, with its outer perimeter connected to the inner perimeter of the fixed ring, and its upper end face is uniformly provided with multiple external electric flame nozzles that extend to its lower bottom surface.

[0013] The outer diameter of the lower end of the pot ring is equal to the inner diameter of the annular recess, so that it can be fitted into the annular recess.

[0014] According to one embodiment of the present invention, the upper end face of the fixing ring is evenly provided with a plurality of fixing holes around its inner periphery; the upper end face of the outer furnace body is evenly provided with a plurality of screw holes corresponding to the plurality of fixing holes around its outer periphery.

[0015] The outer furnace body is fixed to the fixing ring as a whole by fastening bolts that pass through multiple sets of fixing holes and screw holes in opposite vertical positions from top to bottom.

[0016] According to one embodiment of the present invention, a waterproof sealing ring is fitted onto the outer wall of the annular recessed portion, which abuts against the mounting opening.

[0017] According to one embodiment of the present invention, the outer diameter of the pot ring gradually decreases from bottom to top, and a plurality of support blocks for supporting cooking utensils are evenly protruding upwards from the circumference of the pot ring.

[0018] According to one embodiment of the present invention, the inner ring burner head includes an inner furnace body and an elastic grounding probe disposed vertically at the center of the upper end face of the inner furnace body;

[0019] The upper surface of the inner furnace body is uniformly provided with multiple internal electric flame nozzles that extend to its lower bottom surface around the elastic grounding probe. The outer wall of the inner furnace body is provided with external threads, and the inner wall of the outer furnace body is provided with internal threads that are threadedly connected to the external threads.

[0020] According to one embodiment of the present invention, the electric flame generating device includes a power supply module, a rectifier and filter circuit, a main controller, a first high-frequency inverter circuit, multiple first electrode needles, a first resonant boost circuit, a second high-frequency inverter circuit, multiple second electrode needles, and a second resonant boost circuit.

[0021] The rectifier and filter circuit is connected between the power supply module and the main controller;

[0022] The first high-frequency inverter circuit is connected between the main controller and the first resonant boost circuit; multiple first electrode pins are connected to the output terminal of the first resonant boost circuit, and multiple first electrode pins are correspondingly inserted into multiple external electric flame nozzles;

[0023] The second high-frequency inverter circuit is connected between the main controller and the second resonant boost circuit; multiple second electrode pins are connected to the output terminal of the second resonant boost circuit, and multiple second electrode pins are correspondingly inserted into multiple internal electric flame nozzles;

[0024] Both the first rotary switch and the second rotary switch are connected to the main controller.

[0025] According to one embodiment of the present invention, the electric flame generating device further includes an air blowing fan disposed in the stove body;

[0026] The blowing fan is connected to the main controller and is located at the bottom center of the mounting port, with its air outlet direction facing the multiple external electric flame nozzles and the multiple internal electric flame nozzles.

[0027] According to one embodiment of the present invention, the electric flame generating device further includes a blower and an exhaust fan disposed in the stove body;

[0028] Both the exhaust fan and the venting fan are connected to the main controller; the right end face of the stove body is provided with an air inlet, and the left end face is provided with an air outlet; the exhaust fan is located inside the air inlet to draw air into the stove body; the venting fan is located inside the air outlet to exhaust air out of the stove body.

[0029] The beneficial effects of this utility model are:

[0030] Firstly, in practical implementation, the electric flame generated by this application is arranged in zones. When the pot contains a large amount of food or water, the electric flame can be driven to emerge from the outer burner head to use this application, or the electric flame can be driven to emerge from both the outer burner head and the inner burner head to use this application, in order to heat the large amount of food or water in the pot. When the pot contains a small amount of food or water, the electric flame can be driven to emerge from the inner burner head to use this application, in order to heat the small amount of food or water in the pot. In this case, the energy consumption of the electric flame generating device can be greatly reduced, thus saving resources.

[0031] Secondly, when the outer ring burner is damaged, the inner ring burner can be used temporarily alone, and when the inner ring burner is damaged, the outer ring burner can be used temporarily alone. This allows the application to meet emergency needs as much as possible. Alternatively, the outer ring burner and the inner ring burner can be used alternately at certain intervals to allow the outer ring burner or the inner ring burner to cool down when not in use, thereby greatly increasing their service life.

[0032] Thirdly, each of the multiple external and internal electric flame nozzles forms a flame channel from bottom to top. An upward-blowing air fan is installed inside the stove body. When the electric flames generated by the multiple first and second electrode needles are blown upwards through the multiple external and internal electric flame nozzles, the upper outlets of both the external and internal electric flame nozzles are narrowed, resulting in a more elongated flame. This allows for better contact with the bottom of the pot mounted on the pot ring for heating, leading to a better overall flame output and thus a better overall cooking effect.

[0033] Fourthly, by setting up the exhaust fan, air inlet, and air outlet, the air flow inside the stove body of this application is greatly accelerated, so that the electric flame generator and other electrical components set inside the stove body of this application have good heat dissipation effect and long service life.

[0034] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0062] The electric flame partitioned electric flame stove 1000 of this utility model embodiment is described in detail below with reference to the accompanying drawings.

[0063] Reference Figure 1 and Figure 2 As shown, the electric flame partitioned electric flame stove 1000 according to an embodiment of the present utility model includes a stove body 10, and an electric flame generating device 20 is provided inside the stove body 10. The improvement of the present utility model is that it also includes an outer ring burner 30, an inner ring burner 40, a first rotary switch 50 for adjusting the size of the outer ring electric flame and controlling the outer ring electric flame to emerge from the outer ring burner 30, and a second rotary switch 60 for adjusting the size of the inner ring electric flame and controlling the inner ring electric flame to emerge from the inner ring burner 40.

[0064] The stove body 10 has an installation port 101 on its upper surface; the outer ring burner 30 is formed into a ring structure, and its outer periphery is detachably locked into the installation port 101; the inner ring burner 40 is detachably locked into the outer ring burner 30; the first rotary switch 50 and the second rotary switch 60 are both connected to the electric flame generating device 20.

[0065] Based on the above, it is clear that this application is mainly used as an electric flame zoned electric flame stove 1000 in specific implementation.

[0066] Specifically, when applying this application, the application is assembled according to the structure described above. When operating the first rotary switch 50, it is possible to control the electric flame generating device 20 to generate an electric flame of the required size and emit it from the outer ring burner 30. When operating the second rotary switch 60, it is possible to control the electric flame generating device 20 to generate an electric flame of the required size and emit it from the inner ring burner 40. When a pot is placed on the stove body 10 described in this application, it is easy to use the electric flame emanating from the outer ring burner 30 and / or the electric flame emanating from the inner ring burner 40 to heat the food or water contained in the pot.

[0067] Clearly, the use of this application as described above will have the following technical effects:

[0068] On the one hand, the generated electric flame is zoned. When the pot contains a large amount of food or water, the electric flame can be driven to emerge from the outer burner 30 alone, or the electric flame can be driven to emerge from both the outer burner 30 and the inner burner 40 simultaneously to heat the larger amount of food or water in the pot. When the pot contains a smaller amount of food or water, the electric flame can be driven to emerge from the inner burner 40 alone to heat the smaller amount of food or water in the pot. In this case, the energy consumption of the electric flame generating device 20 can be greatly reduced, thus saving resources.

[0069] On the other hand, when the outer ring burner 30 breaks down, the inner ring burner 40 can be used temporarily alone, and when the inner ring burner 40 breaks down, the outer ring burner 30 can be used temporarily alone. This allows the application to meet emergency needs as much as possible. Alternatively, the outer ring burner 30 and the inner ring burner 40 can be used alternately at certain intervals to allow the outer ring burner 30 or the inner ring burner 40 to cool down when not in use, thereby greatly increasing their service life.

[0070] Furthermore, through the above-mentioned optimized design, the whole constituted by this application is highly practical and has a good effect in use.

[0071] Furthermore, in specific implementation, in accordance with... Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the outer ring burner 30 includes a fixing ring 301, an outer burner body 302, and a pot ring 303 with both upper and lower ends being open to support cooking utensils.

[0072] Wherein, the outer diameter of the fixing ring 301 is slightly larger than the inner diameter of the mounting opening 101, so that its outer periphery is adapted to be supported by the inner edge of the mounting opening 101, and the middle part of the fixing ring 301 is recessed downward to form a ring-shaped recessed portion 3011 that fits the interference fit and is locked into the mounting opening 101.

[0073] Furthermore, the outer furnace body 302 is a hollow ring structure, with its outer periphery connected to the inner periphery of the fixed ring 301, and its upper end face is uniformly provided with a plurality of external electric flame nozzles 3021 that penetrate to its lower bottom surface;

[0074] Furthermore, the outer diameter of the lower end of the pot ring 303 is equal to the inner diameter of the annular recess 3011, so as to fit into the annular recess 3011 with an interference fit.

[0075] In this regard, it is clear that when using this application, on the one hand, the outer periphery of the fixed ring 301 is supported by the inner edge of the mounting port 101, and the annular recess 3011 formed by the downward indentation in the middle of the fixed ring 301 is interference-fitted into the mounting port 101. In this way, the outer ring burner 30 of this application is securely mounted at the mounting port 101 and is not easy to shift or slip out circumferentially. On the other hand, when operating the first knob switch 50, it is possible to control the electric flame generating device 20 to generate an electric flame of the required size and spray it out from multiple external electric flame nozzles 3021, so that the food or water contained in the pot mounted on the pot ring 303 can be heated evenly in the circumference.

[0076] Furthermore, in the specific implementation, we will continue to refer to... Figure 4 , Figure 5 and Figure 6 As shown, according to one embodiment of the present invention, the upper end face of the fixing ring 301 is evenly provided with a plurality of fixing holes 3012 around its inner periphery; the upper end face of the outer furnace body 302 is evenly provided with a plurality of screw holes 3022 corresponding to the plurality of fixing holes 3012 around its outer periphery.

[0077] Based on this, the outer furnace body 302 described in this application is fixed to the fixing ring 301 by fastening bolts that pass through multiple sets of fixing holes 3012 and screw holes 3022 in opposite vertical positions from top to bottom.

[0078] It should be noted that the reason why the outer ring burner 30 includes a fixing ring 301, an outer furnace body 302, and a pot ring 303 is that, in actual use, the temperatures of the fixing ring 301 and the pot ring 303 are not very high, resulting in a long service life. However, the temperature of the outer furnace body 302 is very high during use, making it prone to aging and failure after a certain period of use. In this case, the outer furnace body 302 can be removed for independent maintenance or replacement, instead of replacing the fixing ring 301 and the pot ring 303 each time, thereby reducing the maintenance cost of the outer ring burner 30 of this application.

[0079] Furthermore, through the above-mentioned optimized design, the overall performance of this application can be effectively improved.

[0080] Preferably, in this technical solution, compared with Figure 6 As shown, according to one embodiment of the present invention, the outer wall of the annular recess 3011 is fitted with a waterproof sealing ring 3013 that abuts against the mounting opening 101.

[0081] Thus, when the fixing ring 301 is snapped into the mounting port 101, the waterproof sealing ring 3013 will abut against the inner wall of the mounting port 101, which can better prevent water stains that may exist on the upper surface of the stove body 10 from entering the stove body 10 through the mounting port 101, so that the stove body 10 of this application has a good waterproof effect inside.

[0082] Furthermore, in a specific implementation, according to one embodiment of the present invention, the outer diameter of the pot ring 303 gradually decreases from bottom to top, and a plurality of support blocks 3031 for supporting cooking utensils are evenly protruding upward from the circumference of the pot ring 303.

[0083] Therefore, it is clear that by setting the pot ring 303, it is not only used to support the pot, but also to block water and oil stains, so as to better prevent external water and oil stains from splashing onto the surface of the outer ring burner 30 and the inner ring burner 40 and getting them dirty. This makes it a dual-purpose unit, so that the surface of the outer ring burner 30 and the inner ring burner 40 have good anti-pollution effect, which can greatly reduce the number of times the surface of the outer ring burner 30 and the inner ring burner 40 needs to be cleaned.

[0084] Meanwhile, as the outer diameter of the pot ring 303 gradually decreases from bottom to top, the pot ring 303 is formed into a hollow frustum-shaped structure, making its upper opening smaller, thus forming a constricted opening. This makes it less likely for external water and oil stains to enter through its upper opening and contaminate the outer ring burner head 30 and the inner ring burner head 40, and also makes it stable to place.

[0085] Furthermore, since the pot ring 303 has a plurality of support blocks 3031 that are evenly protruding upward on the upper edge of the upper edge to support the pot, it is easy to form air convection inside and outside the pot ring 303.

[0086] Furthermore, in specific implementation, it is necessary to refer to... Figure 4 and Figure 5 As shown, according to one embodiment of the present invention, the inner ring burner head 40 includes an inner furnace body 401 and an elastic grounding probe 402 for circuit return, which is vertically disposed in the middle of the upper end face of the inner furnace body 401.

[0087] The inner furnace body 401 has multiple internal electric flame nozzles 4011 that are evenly arranged upward around the elastic grounding probe 402 on its upper end surface and extend to its lower bottom surface. The outer wall of the inner furnace body 401 is provided with an external thread 4012, and the inner wall of the outer furnace body 302 is provided with an internal thread 3023 that is threadedly connected to the external thread 4012.

[0088] Therefore, it is clear that by setting the elastic grounding probe 402, even when its top touches the bottom surface of the pot, the circuit can be grounded and the current can be returned, making the use of this application safe.

[0089] Furthermore, when the outer wall of the inner furnace body 401 is provided with an external thread 4012 and the inner wall of the outer furnace body 302 is provided with an internal thread 3023 that is threadedly connected to the external thread 4012, the inner furnace body 401 and the outer furnace body 302 can be threadedly connected. On the one hand, this ensures the stability of the connection, making it convenient for the stable use of the inner furnace body 401. On the other hand, it also facilitates the disassembly of the inner furnace body 401. After a certain period of use, when it ages and breaks down, the inner furnace body 401 can be disassembled for independent maintenance or replacement, instead of having to replace the outer furnace body 302 every time, thus reducing the overall maintenance cost of this application.

[0090] Furthermore, in specific implementation, it is necessary to refer to... Figure 2 , Figure 4 , Figure 7 and Figure 8 As shown, according to one embodiment of the present invention, the electric flame generating device 20 includes a power supply module 201 for inputting AC power, a rectifier and filter circuit 202 for rectifying and filtering the AC power to output DC power, a main controller 203, a first high-frequency inverter circuit 204 for inverting the DC power to form a first high-frequency square wave signal, multiple first electrode needles 205, a first resonant boost circuit 206 for resonantly boosting the first high-frequency square wave signal to convert it into a first high-voltage sine wave signal and outputting it to the multiple first electrode needles 205, a second high-frequency inverter circuit 207 for inverting the DC power to form a second high-frequency square wave signal, multiple second electrode needles 208, and a second resonant boost circuit 209 for resonantly boosting the second high-frequency square wave signal to convert it into a second high-voltage sine wave signal and outputting it to the multiple second electrode needles 208.

[0091] The first rotary switch 50 is used to control the first high-frequency inverter circuit 204 to output a first high-frequency square wave signal with a preset amplitude or frequency to the first resonant boost circuit 206; the second rotary switch 60 is used to control the second high-frequency inverter circuit 207 to output a second high-frequency square wave signal with a preset amplitude or frequency to the second resonant boost circuit 209.

[0092] The rectifier and filter circuit 202 is connected between the power module 201 and the main controller 203;

[0093] The first high-frequency inverter circuit 204 is connected between the main controller 203 and the first resonant boost circuit 206; multiple first electrode needles 205 are all connected to the output terminal of the first resonant boost circuit 206, and multiple first electrode needles 205 are correspondingly inserted into multiple external electric flame nozzles 3021.

[0094] The second high-frequency inverter circuit 207 is connected between the main controller 203 and the second resonant boost circuit 209; multiple second electrode needles 208 are connected to the output terminal of the second resonant boost circuit 209, and multiple second electrode needles 208 are correspondingly inserted into multiple internal electric flame nozzles 4011.

[0095] Both the first rotary switch 50 and the second rotary switch 60 are connected to the main controller 203.

[0096] Therefore, by manipulating the first rotary switch 50, the first high-frequency inverter circuit 204 is controlled to output a first high-frequency square wave signal with a preset amplitude (PWM) or frequency (PFM) to the first resonant boost circuit 206. This allows the first resonant boost circuit 206 to resonantly boost the received first high-frequency square wave signal with a preset amplitude (PWM) or frequency (PFM) to convert it into a first high-voltage sine wave signal of a preset magnitude and output it to multiple first electrode needles 205. This allows the multiple first electrode needles 205 to break down the air and generate plasma discharge after being subjected to a preset high voltage, thereby generating an open flame of a preset magnitude. This makes the size of the electric flame ejected from the multiple external electric flame nozzles 3021 adjustable.

[0097] Similarly, by operating the second rotary switch 60, the second high-frequency inverter circuit 207 is controlled to output a second high-frequency square wave signal with a preset amplitude (PWM) or frequency (PFM) to the second resonant boost circuit 209. This allows the second resonant boost circuit 209 to resonate and boost the received second high-frequency square wave signal with the preset amplitude (PWM) or frequency (PFM) to convert it into a second high-voltage sine wave signal of a preset size and output it to multiple second electrode needles 208. This allows the multiple second electrode needles 208 to break down the air and generate plasma discharge after being subjected to a preset high voltage, thereby generating an open flame of a preset size. This makes the size of the electric flame ejected from the multiple internal electric flame nozzles 4011 adjustable.

[0098] It should be noted that in the field of electric flame stoves, the circuit design of sequentially connecting the rectifier filter circuit 202, the high-frequency inverter circuit, the resonant boost circuit, and the electrode needle to generate plasma discharge by applying high voltage to the electrode needle and breaking down the air, thereby producing an open flame, and setting a knob switch to adjust the size of the electric flame, is a mature existing technology. For example, the invention patent "A Plasma Flame Stove Circuit and Plasma Flame Stove" disclosed in patent number "202110872413.9" and the utility model patent "Electrically Generated Open Flame Circuit and Electric Flame Stove" disclosed in patent number "202022125007.X" are both mature existing technologies. This application simply sets it to two paths to achieve electric flame partitioning of the electric flame stove, so that the outer ring burner 30 and the inner ring burner 40 can output electric flames of the same or different sizes at the same time, or so that the outer ring burner 30 and the inner ring burner 40 can output electric flames of the same or different sizes independently.

[0099] Therefore, it is clear that this application mainly improves the physical structure and circuit layout of the electric flame stove. As for the circuit principle itself, there is basically no need to improve it, and existing technology can be directly adopted. Therefore, the specific circuit details between the various circuit modules set in this application will not be described in detail in this patent application document.

[0100] Furthermore, in specific implementation, in accordance with... Figure 2 As shown, according to one embodiment of the present invention, the electric flame generating device 20 further includes an air blowing fan 210 disposed inside the stove body 10;

[0101] The air blowing fan 210 is connected to the main controller 203, and the air blowing fan 210 is located at the bottom center of the mounting port 101. Its air outlet direction is towards the multiple external electric flame nozzles 3021 and the multiple internal electric flame nozzles 4011, and the upper parts of the multiple external electric flame nozzles 3021 and the upper parts of the multiple internal electric flame nozzles 4011 are all formed as constricted openings.

[0102] Preferably, in this application, the comparison Figure 7 As shown, the electric flame generating device 20 also includes a main control circuit board 213 located at the lower part of the mounting port 101; the main control circuit board 213 has a mounting port 2131 in the middle; the air blowing fan 210 is detachably fixed to the mounting port 2131; multiple first electrode needles 205 and multiple second electrode needles 208 are all vertically arranged on the upper surface of the main control circuit board 213, and are all evenly arranged around the mounting port 2131, and the multiple first electrode needles 205 are located outside the multiple second electrode needles 208.

[0103] Therefore, it can be clearly understood that the multiple external electric flame nozzles 3021 and the multiple internal electric flame nozzles 4011 will form flame channels from bottom to top inside. The upward blowing fan 210 is provided inside the stove body 10 so that the electric flames generated by the multiple first electrode needles 205 and the multiple second electrode needles 208 are blown upward by the multiple external electric flame nozzles 3021 and the multiple internal electric flame nozzles 4011. Since the upper outlets of the multiple external electric flame nozzles 3021 and the multiple internal electric flame nozzles 4011 are all formed into constricted openings, they are smaller. This makes the electric flames blown out through their upper outlets more slender, so that they can better contact the bottom of the pot mounted on the pot ring 303 to heat it. This makes the overall flame effect better when the application is used, and thus the overall cooking effect is better.

[0104] It should be added that, in specific implementation, comparison should be made with... Figure 2 , Figure 3 and Figure 8 As shown, according to one embodiment of the present invention, the electric flame generating device 20 further includes a blower 211 and an exhaust fan 212 disposed in the stove body 10;

[0105] The exhaust fan 211 and the venting fan 212 are both connected to the main controller 203; the right end face of the stove body 10 is provided with an air inlet 102 and the left end face is provided with an air outlet 103; the exhaust fan 211 is located in the air inlet 102 to exhaust air into the stove body 10; the venting fan 212 is located in the air outlet 103 to exhaust air out of the stove body 10.

[0106] Thus, by setting up the exhaust fan 211, the exhaust fan 212, the air inlet 102 and the exhaust outlet 103, the air flow inside the stove body 10 of this application is greatly accelerated, so that the electrical components such as the electric flame generator set inside the stove body 10 of this application have good heat dissipation effect and long service life.

[0107] Furthermore, in a specific implementation, according to one embodiment of this utility model, the upper surface of the stove body 10 is preferably made of tempered glass to ensure good oil resistance and make it easy to clean the oil stains on its upper surface by wiping or other means.

[0108] Other embodiments are not described here.

[0109] In summary, in practical implementation, the electric flame generated by this application is arranged in zones. When the pot contains a large amount of food or water, the electric flame can be driven solely from the outer burner head 30 to use this application, or the electric flame can be driven simultaneously from both the outer burner head 30 and the inner burner head 40 to use this application, in order to heat the larger amount of food or water in the pot. When the pot contains a smaller amount of food or water, the electric flame can be driven solely from the inner burner head 40 to use this application, in order to heat the smaller amount of food or water in the pot. In this case, the energy consumption of the electric flame generating device 20 can be greatly reduced, thus saving resources.

[0110] Furthermore, when the outer ring burner 30 fails, the inner ring burner 40 can be used temporarily alone, and when the inner ring burner 40 fails, the outer ring burner 30 can be used temporarily alone. This allows the application to meet emergency needs as much as possible, and alternatively, the outer ring burner 30 and the inner ring burner 40 can be used alternately at certain intervals to allow the outer ring burner 30 or the inner ring burner 40 to cool down when not in use, thereby greatly increasing their service life.

[0111] Furthermore, each of the multiple external electric flame nozzles 3021 and the multiple internal electric flame nozzles 4011 forms a flame channel from bottom to top. An upward-blowing air fan 210 is provided inside the stove body 10 so that the electric flames generated by the multiple first electrode needles 205 and the multiple second electrode needles 208 are blown upward through the multiple external electric flame nozzles 3021 and the multiple internal electric flame nozzles 4011. Since the upper outlets of the multiple external electric flame nozzles 3021 and the multiple internal electric flame nozzles 4011 are all formed into constricted openings, they are smaller, so that the electric flames blown out through their upper outlets are more slender, so that they can better contact the bottom of the pot mounted on the pot ring 303 to heat it. This makes the overall flame output effect better when the application is in use, and thus the overall cooking effect is better.

[0112] Furthermore, by setting up the exhaust fan 211, the exhaust fan 212, the air inlet 102, and the exhaust outlet 103, the air flow inside the stove body 10 of this application is greatly accelerated, so that the electrical components such as the electric flame generator set inside the stove body 10 of this application have good heat dissipation effect and long service life.

[0113] Furthermore, the electric flame zoned electric flame stove 1000 provided in this application is indeed highly practical and has excellent performance, which makes this application inherently valuable for market promotion and will certainly be very popular and effectively popularized.
