Description

Technical Field

[0001] This invention relates to the field of electric arc stove technology, and in particular to a heat-circulating electric arc stove. Background Technology

[0002] Current electric stoves use resistance heating. A characteristic of resistance heating is that if prolonged high-temperature heating is required without the resistance wire melting, the cross-section of the wire needs to be increased. Based on the conductivity properties of materials, the cross-section of the resistance wire is inversely proportional to its resistance. When the cross-section of the wire increases, the resistance decreases, resulting in a larger current and a proportionally amplified heating power. Because resistance heating stoves are difficult to use in homes, high-power heating is difficult, leading to slow and uneven heating of food.

[0003] In conclusion, the existing structure obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

Specifically, the electric arc stove includes a stove body, a circulating chamber outer shell, an air duct, and a fan. The interior of the stove body forms a heating chamber, and an electric arc generator is disposed at its bottom, with the arc-generating end of the electric arc generator located within the heating chamber. A wind cavity is formed at the bottom of the arc-generating end facing the circulating chamber, and at least one air inlet hole is formed at the arc-generating end corresponding to the wind cavity. The wind cavity communicates with the heating chamber through the air inlet hole.

The outer shell of the circulation chamber is located on the outer side of the bottom of the stove body, forming the circulation chamber between it and the stove body. The circulation chamber communicates with the air cavity to form an air inlet channel. After the arc generator heats the air in the heating chamber to a preset temperature, the fan starts working. The fan head is located inside the air cavity, with the air outlet side of the fan head close to the air inlet hole and the air inlet side of the fan head close to the circulation chamber. Thus, when the fan starts working, it draws air from the circulation chamber into the air inlet channel and then into the heating chamber through the air inlet hole. During this process, the air comes into contact with the high temperature at the arc-generating end and is thus rapidly heated. Simultaneously, since at least one air duct connects the heated chamber and the circulating chamber to form an air outlet channel, the air heated in the heated chamber enters the circulating chamber through the air duct when the fan is working, thus forming circulating air. The circulating air comes into direct contact with the arc-generating end and is thus rapidly heated, bringing the heated body into contact with the heated chamber. Under the action of the circulating air, the heated body is not only heated quickly but also evenly. Utilizing circulating air for heating can save energy and reduce electricity consumption.

[0047] See Figures 1 to 7 In one embodiment of the present invention, a heat-circulating electric arc stove 100 is provided, comprising:

[0048] The stove body 10 has a heating chamber 11 inside, and an arc generator 12 is provided at the bottom of the stove body 10. The arc generating end of the arc generator 12 is located inside the heating chamber 11. A wind cavity 1211 is opened at the bottom of the arc generating end facing the circulation chamber 21, and at least one air inlet hole 1212 is opened at the arc generating end corresponding to the wind cavity 1211. The wind cavity 1211 is connected to the heating chamber 11 through the air inlet hole 1212.

[0049] The outer shell 20 of the circulation chamber is located on the outer side of the bottom of the stove body 10, and a circulation chamber 21 is formed between it and the stove body 10. The circulation chamber 21 is connected to the air chamber 1211 to form an air inlet channel.

[0050] At least one air duct 15 connects the heated chamber 11 and the circulating chamber 21 to form an air outlet passage;

[0051] The fan 30 has a fan head 31 located inside the air chamber 1211. The air outlet side of the fan head 31 is located near the air inlet hole 1212, and the air inlet side of the fan head 31 is located near the circulation chamber 21.

[0052] In this embodiment, the electric arc stove 100 utilizes an electric arc for heating. Electric arc heating can generate high temperatures to heat food within a relatively low heating power (generally less than 3500W). The electric arc stove includes a stove body 10, which allows cookware and other heat-receiving objects to come into contact with its heating chamber 11 for heating. An electric arc generator 12 is installed on the stove body 10. The electric arc generator 12 generates an electric arc, which is produced at the arc-generating end. The heat generated by the electric arc is conducted through the arc-generating end to the air in the heating chamber 11, heating the air inside the heating chamber 11. A wind chamber 1211 is formed at the bottom of the arc-generating end facing the circulation chamber 21. A fan head 31 is located inside the wind chamber 1211. When the fan 30 operates, it draws air from the circulation chamber 21 into the air inlet channel and then into the heating chamber 11 through the air inlet 1212. During this process, the air fully and directly contacts the arc-generating end, thus being rapidly heated. The heated air then enters the heating chamber 11. When the fan 30 is operating, because the air outlet side of the fan head 31 is located near the air inlet 1212 and the air inlet side of the fan head 31 is located near the circulation chamber 21, air in the circulation chamber 21 is drawn into the heating chamber 11, creating a negative pressure between the circulation chamber 21 and the heating chamber 11. The heated air in the heating chamber 11 then enters the circulation chamber 21 through the air guide duct 15, thus forming circulating air. Optionally, four air guide ducts 15 are provided and evenly distributed to accelerate the air circulation speed in the heating chamber 11 and the circulation chamber 21. During the operation of the fan 30, the circulating air comes into direct contact with the arc generating end, thus being rapidly heated. Under the action of the circulating air, the heated body is not only heated quickly but also evenly. Furthermore, using circulating air for heating saves energy and reduces electrical consumption.

[0053] As an optional embodiment, see Figures 1-3 The air duct 15 is disposed on the inner wall of the stove body 10 and / or the inner wall of the circulation chamber shell 20; one end of the air duct 15 extends toward the heated chamber 11 and extends to near the top of the stove body 10, and the other end extends toward the circulation chamber 21 and extends at least to near the top of the circulation chamber shell 20.

[0054] In this embodiment, since the heated air in the heated chamber 11 rises, one end of the air guide duct 15 is extended to near the top of the cooktop 10 to guide the hot air from the top of the cooktop 10 into the circulation chamber 21. Since the top of the circulation chamber housing 20 is closer to the air cavity 1211, the other end of the air guide duct 15 is extended to near the top of the circulation chamber housing 20. Furthermore, having the air guide duct 15 near the top of the circulation chamber housing 20 without extending into it makes its installation more convenient. Of course, the other end of the air guide duct 15 can extend into the circulation chamber housing 20.

[0055] As an optional embodiment, see Figures 1-3 The top of the stove body 10 has an opening 13 so that the pot or other heated object can cover the opening 13 and come into contact with the heated chamber 11.

[0056] As an optional embodiment, see Figures 1-3 The heat circulation electric arc stove 100 also includes an electrical cavity shell, which forms an electrical chamber inside. The electrical chamber is equipped with a power supply component and a motor 32 of the fan 30. The motor 32 is electrically connected to the fan head 31. The power supply component is electrically connected to the arc generator 12 and the motor 32 respectively.

[0057] In this embodiment, the electrical cavity housing is optionally connected to the lower part of the circulation cavity housing 20. The electrical cavity housing is used to install the power supply components and the motor 32 of the fan 30, etc. The power supply components can obtain power by installing a battery on the electrical cavity housing, or they can be connected to an external power source through an external power cable.

[0058] As an optional embodiment, see Figures 1-3 The electrical cavity shell includes an upper electrical cavity shell 41 and a lower electrical cavity shell 42. The first inner cavity 412 of the upper electrical cavity shell 41 and the second inner cavity 421 of the lower electrical cavity shell 42 form an electrical cavity. The upper electrical cavity shell 41 is provided with a layered plate 411, which divides the first inner cavity 412 into an upper cavity 4121 and a lower cavity 4122. The lower cavity 4122 communicates with the second inner cavity 421 of the lower electrical cavity shell 42.

[0059] The layered plate 411 is provided with a motor mounting groove 4111 that communicates with the lower cavity 4122, and the motor mounting groove 4111 protrudes towards the upper cavity 4121; the outer shell 20 of the circulation cavity is provided with a through groove 22 that is adapted to the motor mounting groove 4111, the through groove 22 extends to the upper cavity 4121, and the motor mounting groove 4111 is embedded in the through groove 22 to close the through groove 22;

[0060] The motor 32 is located in the lower cavity 4122 and is set in the motor mounting slot 4111. A connecting rod 33 is connected between the motor 32 and the fan head 31. An opening 4112 adapted to the connecting rod 33 is opened on one side of the motor mounting slot 4111 facing the through slot 22.

[0061] In this embodiment, the layered plate 411 is used to provide a motor mounting slot 4111 to facilitate the installation of the motor 32. To facilitate the connection between the motor 32 and the fan head 31, a connecting rod 33 is provided between the fan head 31 and the motor 32. The motor mounting slot 4111 on the layered plate 411 is adapted to the through slot 22 on the circulation chamber housing 20, and the upper cavity 4121 of the motor mounting slot 4111 protrudes, with the through slot 22 extending to the upper cavity 4121. Thus, the motor mounting slot 4111 can close the through slot 22, which not only reduces heat loss within the circulation chamber 21 but also prevents heat conduction from the circulation chamber 21 to the electrical chamber, thus avoiding interference with the power supply components and the operation of the motor 32.

[0062] As an optional embodiment, see Figures 4-7 The arc generator 12 includes a cathode conductive element 121, at least one pair of electrodes, at least one insulating heat-conducting tube 124, at least one conductive column 125, and at least one insulating heat-insulating tube 126.

[0063] The bottom of the cathode conductive element 121 facing the circulation chamber 21 has at least one electrode mounting hole 1213;

[0064] Each electrode mounting hole 1213 has an electrode pair installed inside it; the electrode pair includes a cathode ion head 122 and an anode ion head 123; the cathode ion head 122 is close to the inside of the electrode mounting hole 1213 and is located at the end away from the circulation chamber 21, and the cathode ion head 122 is electrically connected to the cathode conductive element 121.

[0065] The insulating heat pipe 124 has a hollow structure. The anode ion head 123, which corresponds to the cathode ion head 122, is disposed inside the insulating heat pipe 124 and is located at the end of the electrode mounting hole 1213 near the circulation chamber 21. The insulating heat pipe 124 is disposed close to the inside of the electrode mounting hole 1213, and there is a gap between the cathode ion head 122 and the anode ion head 123.

[0066] The cathode conductive element 121, the electrode pair, and the insulating heat pipe 124 form an arc generating end; the bottom of the cathode conductive element 121 is provided with a wind cavity 1211 facing the circulation chamber 21; the top of the cathode conductive element 121 is provided with at least one air inlet hole 1212 corresponding to the wind cavity 1211.

[0067] One end of the anodic ion head 123 facing the circulation chamber 21 is electrically connected to one end of the conductive column 125, and the outer peripheral wall of the conductive column 125 is wrapped with an insulating heat-insulating tube 126;

[0068] The cathode conductive element 121 is electrically connected to the power supply component; the other end of the conductive post 125 is electrically connected to the power supply component.

[0069] In this embodiment, each electrode pair is respectively disposed inside the respective electrode mounting holes 1213 of the cathode conductive element 121. Thus, the electric arc generated between the electrode pairs is located inside the electrode mounting holes 1213, preventing the user from contacting the arc. The cathode ion head 122 is in close contact with the electrode mounting holes 1213, allowing for electrical connection and direct heat transfer from the cathode ion head 122 to the cathode conductive element 121. An insulating heat-conducting pipe 124 is provided between the anode ion head 123 and the cathode conductive element 121. Optionally, the insulating heat-conducting pipe 124 is a magnesium oxide pipe. The insulating heat-conducting pipe 124 prevents short circuits between the anode ion head 123 and the cathode ion head 122 and transfers heat from the anode ion head 123 to the cathode conductive element 121. Optionally, one end of the insulating heat-conducting pipe 124 abuts against the cathode ion head 122, and the other end is flush with the end face of the electrode mounting hole 1213. The cathode ion head 122 and anode ion head 123 of the same electrode pair are spaced apart to facilitate the generation of an electric arc. The electric arc can release high temperatures instantaneously, and the heat from the arc is conducted to the cathode conductive element 121 through the insulated heat-conducting pipe 124. The anode ion head 123 is positioned close to the circulation chamber 21, allowing the conductive post 125 connected to the anode ion head 123 to easily extend from the electrode mounting hole 1213 and pass through the circulation chamber 21 to connect with the power supply component inside the electrical chamber. The outer peripheral wall of the conductive post 125 is wrapped with an insulated heat-insulating pipe 126 to prevent short circuits between the conductive post 125 and the cathode conductive element 121, while also reducing heat conduction between the conductive post 125 and the cathode conductive element 121. The insulated heat-insulating pipe 126 can be selected as an alumina ceramic pipe. The end of the cathode conductive element 121 closest to the circulation chamber 21 can be easily electrically connected to the power supply component inside the electrical chamber via a conductive wire. A wind cavity 1211 is opened at the bottom of the cathode conductive element 121. The fan head 31 of the fan 30 can be installed in the wind cavity 1211. The fan blades of the fan head 31 rotate to draw the air in the circulation chamber 21 into the wind cavity 1211 and then blow it into the heating chamber 11 through the air inlet hole 1212. The air comes into direct contact with the cathode conductive element 121 and quickly obtains the heat of the cathode conductive element 121.

[0070] As an optional embodiment, the electrode mounting hole 1213 is a blind hole (non-through hole) to avoid the exposure of the cathode ion head 122, the anode ion head 123, and the electric arc generated between the cathode ion head 122 and the anode ion head 123, thus preventing user contact.

[0071] See Figure 7 The end of the cathode ion head 122 facing the anode ion head 123 is inverted conical; the end of the anode ion head 123 facing the cathode ion head 122 is conical; the cathode ion head 122 and the anode ion head 123 can stabilize the generated arc through tip discharge.

[0072] See Figure 1 and Figure 3 A limiting ring 14 protrudes from the bottom of the stove body 10 towards the heating chamber 11. A limiting groove 1214, which is adapted to the limiting ring 14, is opened at the bottom of the cathode conductive component 121. The limiting groove 1214 is engaged in the limiting ring 14. The cooperation between the limiting ring 14 and the limiting groove 1214 fixes the cathode conductive component 121 to the stove body 10.

[0073] As an optional embodiment, see Figures 4-6 There are multiple pairs of electrodes, and multiple electrode mounting holes 1213 are provided for each electrode pair. The multiple electrode mounting holes 1213 form a ring and surround the outer periphery of the air cavity 1211, so that the heat generated by the multiple electric arc pairs can be conducted to the air inlet channel and the cathode conductive component 121 around the air inlet channel more quickly. When the fan 30 is working, the air entering the air inlet channel can be heated quickly.

[0074] Multiple conductive pillars 125 are provided with corresponding electrode pairs. Since the multiple electrode pairs are arranged in a ring, the multiple conductive pillars 125 form a ring.

[0075] As an optional embodiment, see Figure 1 The power supply components include:

[0076] The circuit board 51 is disposed in the second inner cavity 421 of the lower shell 42 of the electrical cavity. The circuit board 51 is provided with an anode current circuit and a cathode current circuit. The circuit board 51 can obtain power from the battery in the electrical cavity, or it can be connected to an external power source through an external power supply line.

[0077] Anode wire 52, one end of which is electrically connected to the anode current circuit and the other end of which is electrically connected to the shunt circuit board 53; an installation hole adapted to the anode wire 52 is opened on the upper shell 41 of the electrical cavity, so that the anode wire 52 enters the upper cavity 4121 and connects to the shunt circuit board 53.

[0078] The current shunt circuit board 53 is disposed in the upper cavity 4121; the current shunt circuit board 53 is annular; the circulation cavity shell 20 has a plurality of mounting through holes 23 adapted to the conductive posts 125; each conductive post 125 passes through the corresponding mounting through hole 23 and is electrically connected to the current shunt circuit board 53.

[0079] The cathode wire 54 has one end electrically connected to the cathode current circuit and the other end electrically connected to the cathode conductive element 121. The upper shell 41 of the electrical cavity and the outer shell 20 of the circulation cavity are both provided with mounting holes that are compatible with the cathode wire 54, so that the cathode wire can pass through the upper shell 41 of the electrical cavity and the outer shell 20 of the circulation cavity to connect with the cathode conductive element 121.

[0080] As an optional embodiment, the cathode conductive element 121 is made of a metallic material and is in the shape of a frustum, cylinder, or hemisphere.

[0081] The working process of the heat circulation electric arc stove 100 is as follows:

[0082] The pot or other heated element is placed on top of the stove body 10, so that the pot is in contact with its heating chamber 11. Food is then placed on the pot. The circuit board 51 is connected to an external power source and energized via an external power cord. The anode current of the circuit board 51 is conducted to the anode ion head 123 through the anode wire 52, the shunt circuit board 53, and the conductive post 125. Simultaneously, the cathode current of the circuit board 51 is conducted to the cathode ion head 122 through the cathode wire 54 and the cathode conductive element 121. Due to the gap between the cathode ion head 122 and the anode ion head 123, an electric arc is eventually generated, which rapidly releases high temperature. The high temperature generated by the cathode ion head 122 is directly conducted to the cathode conductive element 121. The high temperature generated by the anode ionizer 123 and the electric arc is introduced to the cathode conductive element 121 through the insulated heat-conducting pipe 124. The insulated heat-conducting pipe 124 is a magnesium oxide pipe, which not only has thermal conductivity but also insulation properties. After the preset heating time, the circuit board 51 supplies power to the motor 32 of the fan 30, and the fan head 31 starts to work to generate circulating air. That is, air is drawn into the heated chamber 11 from the circulation chamber 21 through the air inlet channel. During this process, the air comes into contact with the cathode conductive element 121 and is rapidly heated. The hot air rises after entering the heated chamber 11. Due to the negative pressure between the circulation chamber 21 and the heated chamber 11, the hot air enters the circulation chamber 21 through the four air guide pipes 15. Because the circulating air is rapidly heated, the pot body quickly gains heat and heats the food.

[0083] In summary, the present invention provides a heat-circulating electric arc stove that utilizes the heating characteristics of an electric arc to generate high temperatures with relatively low heating power. Specifically, the electric arc stove includes a stove body, a circulating chamber outer shell, an air duct, and a fan. The stove body forms a heating chamber inside, with an electric arc generator located at its bottom, and the arc-generating end of the electric arc generator situated within the heating chamber. A wind cavity is formed at the bottom of the arc-generating end facing the circulating chamber, and at least one air inlet hole is formed at the arc-generating end corresponding to the wind cavity. The wind cavity communicates with the heating chamber through the air inlet hole. Because the arc-generating end of the electric arc generator is located within the heating chamber, it heats the air in the heating chamber. The outer shell of the circulation chamber is located on the outer side of the bottom of the stove body, forming the circulation chamber between it and the stove body. The circulation chamber communicates with the air cavity to form an air inlet channel. After the arc generator heats the air in the heating chamber to a preset temperature, the fan starts working. The fan head is located inside the air cavity, with the air outlet side of the fan head close to the air inlet hole and the air inlet side of the fan head close to the circulation chamber. Thus, when the fan starts working, it draws air from the circulation chamber into the air inlet channel and then into the heating chamber through the air inlet hole. During this process, the air comes into contact with the high temperature at the arc-generating end and is thus rapidly heated. Simultaneously, since at least one air duct connects the heated chamber and the circulating chamber to form an air outlet channel, the air heated in the heated chamber enters the circulating chamber through the air duct when the fan is working, thus forming circulating air. The circulating air comes into direct contact with the arc-generating end and is thus rapidly heated, bringing the heated body into contact with the heated chamber. Under the action of the circulating air, the heated body is not only heated quickly but also evenly. Utilizing circulating air for heating can save energy and reduce electricity consumption.

[0084] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
