[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] like Figure 1-Figure 5As shown, a multifunctional electric stove requires an external power supply and is specifically applied to household stoves. It includes a housing 1 and an installation cavity 11 located in the housing 1. The installation cavity 11 is provided with a second heating device 3 and an electric stove head composed of a plurality of arc generating devices 2. Both are electrically connected to a control circuit 20. The control circuit 20 is also connected with a control switch 28 for controlling the switch of the electric stove head and the second heating device 3 and adjusting the power thereof to adjust the fire power thereof, thereby heating or keeping the pot warm. In the utility model, the control switch 28 is a knob switch, and can also be a replacement of a touch panel, a physical key switch or other equivalent technologies, which should be understood by those skilled in the art. An opening (not shown in the figure) is provided at a position corresponding to the electric stove head on the housing 1, and the upper part of the electric stove head extends upward from the opening 15 to directly heat the pot. The electric stove head is composed of components such as an arc generating device 2 and a transformer, and is a prior art device that uses a DC electrode to continuously discharge and form a stable DC arc to heat the pot body. Arc is a gas discharge phenomenon. Under a certain voltage, two electrodes are maintained conductive by gaseous charged particles, such as electrons or ions, which excite the sample to produce a spectrum, which is the "electric flame" seen by the naked eye.

[0030] Furthermore, the electric fire burner head and the second heating device 3 are distributed in the installation cavity 11 left and right, and can also be distributed in the installation cavity 11 front and back.

[0031] like Figure 2 , Figure 3 As shown, the arc generating device 2 includes a flamethrower 21 and an insulating component 22. The flamethrower 21 is made of metal, and the insulating component 22 is made of ceramic, so that there is no direct connection between the flamethrower 21 and the electrode below, and the user will not get an electric shock when touching the flamethrower 21. The insulating component 22 includes an insulating seat 221 and an insulating column 222 connected up and down. Specifically, the insulating seat 221 and the insulating column 222 are integrally formed, and a plurality of through holes 223 are provided on the peripheral wall of the insulating seat 221 for air intake into the insulating seat 221. The ignition needle 23 is sleeved in the insulating seat 221, and the lower part of the ignition needle 23 and the insulating column 222 are detachably installed through threads, so that the ignition needle 23 can be quickly disassembled and replaced when it is damaged, without the need to disassemble and repair the entire arc generating device 2. The bottom of the ignition needle 23 is electrically connected to the control circuit 20.

[0032] Further, such as Figure 3 As shown, the flamethrower 21 has upper and lower openings, and the diameter of the upper opening is smaller than that of the lower opening. Since the smaller the pipe opening, the faster the flow rate, after the air enters the flamethrower 21, it flows from the wide opening to the narrow opening and is quickly output, so that the flame on the top of the flamethrower 21 is blown upward by the air in a jet shape, and the oxygen in the air plays a combustion-supporting effect, making the fire more powerful.

[0033] like Figure 2 , Figure 4 As shown, the lower opening of the flamethrower 21 is limitedly placed on the insulating seat 221. Specifically, the top of the insulating seat 221 is provided with an inwardly concave limiting platform 224, so that the top of the insulating seat 221 extends into the flamethrower 21 and the bottom of the flamethrower 21 abuts against the bottom of the limiting platform, so that the flamethrower 21 can be stably placed on the insulating seat 221.

[0034] In order to prevent the electric stove from being in an ignition and burning state when no pot is placed on the electric stove, which may easily cause an accident, an induction safety valve 24 is provided between the arc generating device 2, and the highest point of the induction safety valve 24 is higher than the highest point of the arc generating device 2. The induction safety valve 24 is electrically connected to the control circuit 20. Specifically, the induction safety valve 24 includes a needle, a needle seat and a spring. The spring is sleeved on the lower part of the needle and installed in the needle seat, so that the needle can move up and down elastically. When a pot is placed on the top of the electric stove, the weight of the pot presses the needle downward and releases a signal to the control circuit 20. At this time, it is in a safe state, and the arc generating device 2 can be powered on and ignited. On the contrary, when there is no pot placed above the electric fire stove head, the elasticity of the spring pushes the needle upward. At this time, if the arc generating device 2 is in an ignition and combustion state, the control device 20 stops the arc generating device 2 within a set time to prevent it from dry burning and causing safety hazards. The set time is determined according to actual conditions. In the utility model, it is set to 30 seconds; at this time, if the arc generating device 2 is in a non-ignition state, it will not start working.

[0035] Further, such as Figure 4 As shown, in order to adapt to pots of various shapes, such as frying pans, round bottom pots, etc., which can be used on the electric stove head, a plurality of arc generating devices 2 are respectively surrounded by an outer fire ring 25 and an inner fire ring 26 and are evenly spaced. The horizontal height of the highest point of the outer fire ring 25 is higher than the horizontal height of the highest point of the inner fire ring 26. The tops of the outer fire ring 25 and the inner fire ring 26 are connected to form an arc shape, which is adapted to the bottom shape of the round bottom pot, so that the round bottom pot can be stably placed on the electric stove head, while the frying pan can be placed on the outer fire ring. The induction safety valve 24 is surrounded by the center of the inner fire ring 26, and the induction safety valve 24 can be triggered regardless of which pot is used.

[0036] like Figure 3 As shown, a through hole 223 is provided on the peripheral wall of the insulating seat 221, and the through hole 223 is connected to the flamethrower 21 for replenishing air in the flamethrower 21 so that the flame can continue to burn.

[0037] Further, such as Figure 2As shown, in order to make the flame of the arc generating device 2 stronger, a combustion-supporting air duct 4 connected to the through hole 223 is provided below the electric stove head, and the combustion-supporting air duct 4 includes an air duct base 41, a cover plate 42 and a fan 43. A fan air inlet (not shown in the figure) is provided at the bottom of the housing 1 at a position corresponding to the fan 43. The cover plate 42 is located above the opening 15 of the housing 1, and the air duct base 41 is located below the opening 15. The two are fixedly installed by screws. The arc generating device 2 is located in the cavity between the cover plate 42 and the air duct base 41, and the lower part of the arc generating device 2 is inserted on the air duct base 41, and the upper part passes through the cover plate 42 and protrudes upward from the housing 1. An air duct opening 44 is provided on the air duct base 41, and the fan 43 is installed below the air duct base 41 at a position corresponding to the air duct opening 44 and is electrically connected to the control circuit 20.

[0038] When in use, the fan 43 blows air into the air duct opening 44, and a large amount of air remains in the cavity between the air duct base 41 and the cover plate 42. Since the diameter of the through hole 223 is small, the air flows from the large-diameter area to the small-diameter area, and its flow rate becomes faster. Therefore, the air quickly enters from the through hole 223 and flows into the flamethrower 21, and pushes the flame on the top of the flamethrower 21 upward in a jet shape.

[0039] Furthermore, the cover plate 42 also has an anti-fouling effect, preventing food sauces and the like from dripping into the interior of the electric stove head during cooking.

[0040] Further, such as Figure 1 , Figure 4 As shown, in order to further provide a combustion-supporting environment, a pot ring 45 is placed around the electric fire stove head above the cover plate 42, and a plurality of air supply ports 451 are provided on the upper edge of the pot ring 45 for supplying air into the pot ring 45 so that the flame can continue to burn.

[0041] like Figure 2 , Figure 5 As shown, a heat dissipation device 12 is provided in the installation cavity 11, and the heat dissipation device 12 includes a heat sink 121 and a heat dissipation fan 122. The heat sink 121 is located above the control circuit 20 and on both sides of the electric stove head, and is used to dissipate heat for the electric stove head and the control circuit 20, so as to avoid long-term high-temperature operation, resulting in damage to the components due to long-term high temperature, and effectively prolonging the service life of the device. An air inlet 13 and an air outlet 14 connected to the installation cavity 11 are provided on the opposite side walls of the installation cavity 11. The heat dissipation fan 122 is installed at the position corresponding to the air outlet 14, and is used to dissipate heat for the components inside the installation cavity 11, so as to avoid damage to the components due to long-term high temperature. Specifically, a limit wall 131 is symmetrically arranged at the position corresponding to the air inlet 13 in the installation cavity 11, and the heat dissipation fan 122 is limitedly placed between the two limit walls, so as to facilitate installation, disassembly and maintenance.

[0042] Further, such as Figure 1 , Figure 6 As shown, when cooking, especially when frying, the ingredients need to be fried separately, and the fried ingredients are easy to cool down after being served, which affects the taste and quality when eating. Therefore, in order to increase the practicality of the electric stove, the second heating device 3 is an electric ceramic stove and is electrically connected to the control circuit 20. When the control switch 28 is turned on, the control point 20 controls the electric fire of the electric stove head, and the second heating device 3 is also turned on. The cooked dishes can be placed on the second heating device for insulation, and the food can be kept warm, thereby improving the eating experience of the user when tasting. At the same time, the second heating device 3 can also be used for cooking, saving cooking time.

[0043] Furthermore, one or more second heating devices 3 can be provided according to actual needs, and can be individually controlled through the control panel, which is beneficial to improving the user experience.

[0044] Specifically, the second heating device (3) is an electric ceramic stove, comprising a heating wire and a first heat-conducting panel, the first heat-conducting panel being located at a position of the electric stove panel corresponding to the heating wire, and the heating wire being electrically connected to a control circuit (20). Example

[0045] Different from the above embodiment, the second heating device 3 is an electromagnetic cooker including a heating coil and a second heat-conducting panel, the second heat-conducting panel is located at the position of the electric stove panel corresponding to the heating coil, and the heating coil is electrically connected to the control circuit 20. It can also be used for heating or heat preservation. When the control switch 28 is turned on, the control switch 20 controls the electric fire of the electric stove head, and the second heating device 3 is also turned on at this time. The cooked dishes can be placed on the second heating device for heat preservation, and the food can be kept warm, thereby improving the eating experience of the user when tasting. At the same time, the second heating device 3 can also be used for cooking, saving cooking time.

[0046] Furthermore, since most families are accustomed to using round-bottomed iron pans, and the conventional induction cooker heating panel is flat and not suitable for round-bottomed iron pans, the heating panel of the induction cooker can be set to be concave to fit the shape of the bottom of the round-bottomed iron pan.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any technical solutions that can be obtained by those skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention and on the basis of the prior art should be within the protection scope determined by the claims.
