Description

Technical Field

[0001] This invention relates to the field of electric gas stove technology, and more particularly to an electric gas stove. Background Technology

[0002] An electric gas stove is a new type of stove that uses electricity to start a fire without the need for fuel. It uses clean electricity as its energy source and low-temperature thermal plasma technology as its foundation, with a plasma torch that outputs stable power from multiple points to achieve cooking functions.

[0003] Currently, mainstream electric gas stoves have two major problems. First, they require a conductive pot (such as an iron pot) to connect to the probe (one of the stove's electrodes) to generate high-temperature plasma. The stove automatically extinguishes the flame when the pot is removed, making it unsuitable for use with earthenware or ceramic pots. The second problem is that the high voltage between the two electrodes generates harmful gases like ozone and nitrogen oxides during operation. Since the electrodes are connected to the atmosphere, these ozone and nitrogen oxides escape and continuously generate new ones, polluting the environment. Summary of the Invention

[0004] In view of the above, the present invention provides an electric gas stove to solve at least one of the problems mentioned in the background art.

[0005] To achieve one or more of the above objectives or other objectives, the present invention provides an electric gas stove, comprising: a main body shell and a stove frame structure disposed on the main body shell, the stove frame structure comprising: a pot ring, a pot ring bottom plate, an electrode plate and a bottom plate;

[0006] The bottom plate of the pot ring is disposed on the outer shell body. The bottom plate of the pot ring, the electrode plate and the base plate are stacked in sequence, and a first cavity is formed between the base plate and the electrode plate. The base plate is provided with a plurality of first pin holes. The electrode plate is provided with a plurality of electrode grooves and circulating air holes corresponding to the bottom plate of the pot ring. The bottom of each electrode groove has a guide hole and a second pin hole that connect to the first cavity. A hollow first electrode is disposed on the electrode groove. The electrode plate and the base plate are provided with first electrode needles that pass through the first pin holes and the second pin holes in sequence. One end of the first electrode needle is located outside the base plate, and the other end is located inside the first electrode and connected to a second electrode that does not contact the first electrode. A flow channel connecting the two sides of the electrode plate is formed between the first electrode and the second electrode.

[0007] The pot ring is disposed on the bottom plate of the pot ring and is used to place the pot. When the pot is placed, the pot ring, the bottom plate of the pot ring and the pot form a second cavity.

[0008] Furthermore, the top of the pot ring has an inward-facing chamfer for fitting the cookware, and the center of the chamfer is located on one side of the cookware.

[0009] Furthermore, the bottom plate of the pot ring is provided with an upwardly protruding mesh structure at the position corresponding to the circulating air hole, and the mesh holes on the mesh structure are all higher than the plane of the bottom plate of the pot ring.

[0010] Furthermore, the bottom of the electrode groove is made of an insulating material, and the flow guide hole and the second pin hole are disposed on the flow guide.

[0011] Furthermore, the outer shell body includes a top cover, the top cover is provided with a through hole, and a connecting ring structure with an upward protrusion is provided around the through hole, and the bottom plate of the pot ring is connected to the connecting ring structure.

[0012] Furthermore, the outer casing is provided with a single-electrode circuit board, and the single-electrode circuit board is provided with a plurality of second electrode pins that are electrically connected to each other. The first electrode pin is connected to the second electrode pin, and the single-electrode circuit board is used to connect the second electrode to one pole of the power supply.

[0013] Furthermore, the outer casing also includes a plastic component mounted below the base plate, the unipolar circuit board is mounted inside the plastic component and sealed by potting sealant, and the second electrode needle is located outside the plastic component.

[0014] Furthermore, the outer casing body also includes a heat sink, which is disposed below the plastic part and abuts against the sealant.

[0015] Furthermore, the main body of the housing also includes a motor and a fan. The motor is located below the heat sink, and the fan is located in the first cavity and corresponds to the circulating air vent. The drive shaft of the motor passes through the heat sink, the single-pole circuit board and the base plate in sequence and is connected to the fan.

[0016] Furthermore, the plastic part and the base plate are provided with a preset distance, and the end of the first electrode needle located on the outer side of the base plate is provided with multiple parallel heat dissipation rings.

[0017] Implementing the embodiments of the present invention will have the following beneficial effects:

[0018] With the aforementioned electric stove, when cookware is placed, the pot ring, the pot ring base, and the cookware together form a second cavity. As long as a fan is installed at the location corresponding to the circulation vent in the first cavity, the first and second cavities can circulate. Air from the second cavity can flow into the first cavity through the circulation vent, and air from the first cavity can flow into the second cavity through the guide holes. Simultaneously, since the high-temperature plasma is generated between the first and second electrodes—that is, generated within the flow channel—and does not rely on the cookware as an arc-initiating electrode, the airflow from the first cavity to the second cavity can direct the high-temperature plasma generated between the first and second electrodes onto the cookware. Therefore, non-conductive cookware such as earthenware pots and ceramic pots can also be used on the electric stove. Furthermore, because the generation of ozone and nitrogen oxides is a reversible process, only a certain concentration can be reached in a relatively enclosed space. Since the first and second cavities are not connected to the outside environment, only a very small amount of ozone and nitrogen oxides are generated during operation, effectively reducing the generation of harmful gases.

Detailed Implementation

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects and not to describe a particular order.

[0038] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0039] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0040] Reference Figures 1 to 5 The present invention proposes an electric stove, comprising: a shell body 1 and a stove frame structure 2 disposed on the shell body 1. The shell body 1 includes other parts of the electric stove that are different from the stove frame structure 2, and should not be construed as merely a shell.

[0041] The furnace frame structure 2 includes: a pot ring 21, a pot ring bottom plate 22, an electrode plate 23, and a base plate 24. The pot ring bottom plate 22 is mounted on the outer shell body 1. For example, the outer shell body 1 has a top cover 11 with a through hole 111. A connecting ring structure 112 protruding upwards is provided around the through hole 111. The pot ring bottom plate 22 connects to and seals the connecting ring structure 112. Figure 2 As shown, this design ensures excellent waterproofing at the joints. A microcrystalline plate can also be installed above the top cover 11 for easy cleaning. Figure 2 and Figure 3 As shown.

[0042] The bottom plate 22, electrode plate 23, and bottom plate 24 of the pot ring are stacked sequentially. The bottom plate 24 can be connected to the bottom plate 22 of the pot ring from the bottom or to the aforementioned connecting ring structure 112, and the electrode plate 23 is sandwiched between the bottom plate 22 and the bottom plate 24, forming a first cavity between the bottom plate 24 and the electrode plate 23. Specifically, the bottom plate 24 can be provided with a fan mounting groove and multiple first pinholes 241 penetrating the bottom plate 24. Each first pinhole 241 is provided with a guide groove surrounding the outer periphery of the first pinhole 241 and communicating with the fan mounting groove. When the electrode plate 23 is placed on top of the bottom plate 24, the empty part inside the guide groove forms the first cavity. Figure 8 As shown, the electrode plate 23 is provided with multiple electrode slots 231 corresponding to the bottom plate 22 of the pot ring and circulation holes 232. The circulation holes 232 are connected to the fan mounting slot and to the top of the bottom plate 22 of the pot ring. The multiple electrode slots 231 corresponding to the bottom plate 22 of the pot ring refer to holes in the bottom plate 22 at the positions corresponding to the electrode slots 231. These electrode slots 231 connect to the top of the bottom plate 22 of the pot ring. Figure 4 and Figure 5As shown. Thus, each electrode groove 231 has a guide hole 23111 and a second pin hole 23112 at its bottom, connecting to the first cavity. A hollow first electrode 2313 is then placed on the electrode groove 231. A first electrode needle 25 is passed sequentially through the first pin hole 241 and the second pin hole 23112. One end of the first electrode needle 25 is located outside the base plate 24, and the other end is located inside the first electrode 2313, connecting to a second electrode 2314 that does not contact the first electrode 2313. This forms a flow channel connecting both sides of the electrode plate 23. For example, the first electrode 2313 can be a circular tube, such as... Figure 10 As shown, the second electrode 2314 can be a cylinder. In other embodiments, the first electrode 2313 includes a connecting pipe 23131 and a hollow first burner head 23132, the cross-sectional size of the first burner head 23132 decreasing from the top to the bottom, and the connecting pipe 23131 connecting to the lower end of the first burner head 23132; the second electrode 2314 includes a connecting post 23141 and a second burner head 23142, the cross-sectional size of the second burner head 23142 decreasing from the top to the bottom, and the connecting post 23141 connecting to the lower end of the second burner head 23142, with a connecting groove 231411 at the bottom for connecting the first electrode needle 25. In this case, the first electrode 2313 is shaped like a cup, while the second electrode 2314 is shaped like a stemmed glass. This structural arrangement allows for a larger flame outlet, i.e., a larger area of ​​high-temperature plasma ejected, resulting in more uniform heating of the cookware 3, such as... Figure 9 As shown.

[0043] The pot ring 21 is set on the pot ring base plate 22 for placing the pot 3. When the pot 3 is placed, the pot ring 21, the pot ring base plate 22 and the pot 3 form a second cavity. The above-mentioned flow channel connects the first cavity and the second cavity.

[0044] More specifically, the top of the pot ring 21 has an inward-facing chamfer 211 for fitting the cookware 3. The center of this chamfer 211 is located on one side of the cookware 3. Figures 1 to 6 as well as Figure 13 As shown, this ensures a tighter fit between the cookware 3 and the pot ring 21, regardless of whether a flat-bottomed or round-bottomed pan is used, resulting in better sealing of the second cavity.

[0045] More specifically, the bottom plate 22 of the pot ring has an upwardly protruding mesh structure 221 at the position corresponding to the circulating air hole 232. The mesh holes on the mesh structure 221 are all higher than the plane of the bottom plate 22 of the pot ring. The mesh structure 221 can prevent large foreign objects such as food scraps from entering the first cavity and causing blockage. At the same time, since the mesh structure 221 is upwardly protruding, it also has a certain waterproof function. That is, some water flowing into the bottom plate 22 of the pot ring will not enter the mesh holes because the mesh structure 221 is higher.

[0046] More specifically, the bottom of the electrode groove 231 is composed of an insulating guide member 2311. Guide holes 23111 and second pin holes 23112 are provided on the guide member 2311. The guide member 2311 can be alumina ceramic, which includes a first cylinder and a second cylinder. The first cylinder and the second cylinder are connected to each other to form a T-shaped structure. The second pin holes 23112 are located at the axial position of the guide member 2311. The guide holes 23111 are all provided on the first cylinder. The guide holes 23111 can be inherent in the guide member 2311 itself, or the guide member 2311 can have grooves 23114. After the guide member 2311 is connected to the electrode plate 23, these grooves 23114 form the guide holes 23111. For example, multiple electrode mounting holes are provided on the electrode plate 23, and a limiting ring is provided at the bottom of each electrode mounting hole. The electrode groove 231 is formed by the ceramic tube being installed in the electrode mounting hole and engaging with the limiting ring. The first pinhole 241 and the guide hole 23111 are located on the ceramic tube, and their style can be as follows: Figure 11 and Figure 12 As shown.

[0047] More specifically, the main body 1 of the outer casing is provided with a single-pole circuit board 12, on which a plurality of interconnected second electrode pins 121 are provided. The first electrode pin 25 is connected to the second electrode pins 121. The single-pole circuit board 12 is used to connect the second electrode 2314 to one pole of the power supply. The electrode plate 23 can be a ceramic plate, mica plate, etc., and the bottom plate 22 of the pot ring can be a copper plate, stainless steel plate, etc. The first electrode 2313 can be connected to the bottom plate 22 of the pot ring by threads and the electrode mounting hole on the electrode plate 23 is sealed. The bottom plate 22 of the pot ring can then be connected to the other pole of the power supply.

[0048] More specifically, the outer casing 1 also includes a plastic component 13 mounted below the base plate 24, which must be resistant to high temperatures and high voltages, such as temperatures above 90°C and voltages of 10,000 volts. A single-pole circuit board 12 is installed inside the plastic component 13 and sealed with sealant, while the second electrode pins 121 are located outside the plastic component 13. In this way, after the circuit exits the transformer, the current is distributed to each of the second electrode pins 121 via the circuit board. The sealant can be a hot melt adhesive, primarily to prevent high voltage leakage.

[0049] More specifically, the outer casing 1 also includes a heat sink 14, which is located below the plastic part 13 and abuts against the hot melt adhesive. Since the circuit board generates heat during operation, mainly the heat from the electrode needles, it is also conducted to the circuit board. The heat sink 14 can better dissipate heat from the circuit board. An additional cooling fan can also be set to physically cool the heat sink 14.

[0050] More specifically, the outer casing 1 also includes a motor 15 and a fan 16 (here, fan 16 refers to the fan blades, distinct from the cooling fan mentioned above). The motor 15 is located below the heat sink 14, and the fan 16 is located within the first cavity, corresponding to the circulating air vent 232. The drive shaft of the motor 15 passes sequentially through the heat sink 14, the single-pole circuit board 12, and the base plate 24, connecting to the fan 16. The first and second cavities are high-temperature zones during operation, with temperatures reaching over 1000℃. With the aforementioned arrangement, the motor 15 does not need to be located in these high-temperature zones. The drive shaft of the motor 15 can be fitted with bearings on the base plate 24 as needed to increase sealing.

[0051] More specifically, such as Figure 7 As shown, the plastic part 13 and the base plate 24 are provided with a preset distance. The first electrode needle 25 is provided with multiple parallel heat dissipation rings 251 at one end located on the outer side of the base plate 24. Figure 10 This provides one design for the heat dissipation ring 251. In conjunction with the aforementioned embodiments, the cooling fan can physically cool the heat sink 14 while simultaneously cooling the first electrode pin 25.

[0052] In some embodiments, the present invention also provides an electric gas stove, comprising: a main outer shell 1 and a stove frame structure 2 disposed on the main outer shell 1. The stove frame structure 2 includes: a pot ring 21, a pot ring bottom plate 22, a bottom plate 24, and flow guides 2311. The pot ring bottom plate 22 is disposed on the main outer shell 1, and the bottom plate 24 is connected below the pot ring bottom plate 22, forming a first cavity between the bottom plate 24 and the pot ring bottom plate 22. The bottom plate 24 is provided with a plurality of flow guides 2311. The pot ring bottom plate 22 is provided with a mesh structure 221 and a plurality of electrode holes corresponding to the flow guides 2311. Each flow guide 2311 is provided with an electrode groove 231, such as... Figure 14As shown, the electrode groove 231 has a guide hole 23111 that connects to the first cavity and a third pin hole 23113 that connects to the bottom of the guide member 2311. A hollow first electrode 2313 is provided on the electrode groove 231. A first electrode needle 25 that passes through the guide member 2311 is provided in the third pin hole 23113. One end of the first electrode needle 25 is located outside the bottom plate 24, and the other end is located inside the first electrode 2313 and connected to a second electrode 2314 that does not contact the first electrode 2313. A flow channel is formed between the first electrode 2313 and the second electrode 2314. The pot ring 21 is provided on the bottom plate 22 of the pot ring and is used to place the pot 3. When the pot 3 is placed, the pot ring 21, the bottom plate 22 of the pot ring and the pot 3 form a second cavity. Compared with the electric stove in the previous embodiment, the electric stove in this embodiment omits the electrode plate 23 structure and also omits the flow guide groove. The electrode groove 231 is set on the flow guide 2311. Other parts can be the same as those in the previous embodiment. The overall working principle and technical effect are similar, and will not be described again.

[0053] In summary, the electric gas stove proposed in this invention generates high-temperature plasma between the first electrode 2313 and the second electrode 2314 during operation. The fan 16 drives the air in the first and second chambers to circulate. Air from the second chamber can flow into the first chamber through the circulation vent 232, and air from the first chamber can flow into the second chamber through the guide hole 23111. During this flow, the airflow can direct the high-temperature plasma generated between the first and second electrodes 2313 onto the cookware 3, allowing non-conductive cookware such as clay pots and ceramic pots to be used on the electric gas stove. Throughout the process, hot air outflow is effectively prevented, significantly improving heating efficiency. Furthermore, because the generation of ozone and nitrogen oxides is a reversible process, only a certain concentration can be reached in a relatively enclosed space. Since the first and second chambers are not connected to the outside, only a very small amount of ozone and nitrogen oxides are generated during operation, effectively reducing the generation of harmful gases.

[0054] Obviously, the embodiments described above are merely some embodiments of the present invention, not all embodiments. The accompanying drawings show preferred embodiments of the present invention, but do not limit the patent scope of the present invention. The present invention can be implemented in many different forms; rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this invention.
