Description

Technical Field

[0001] The invention relates to the technical field of electric arc ranges, and in particular to a thermal cycle electric arc range. Background Art

[0002] The stoves that use electric energy for heating in the prior art use resistive heating. There is a characteristic of resistive heating. If long-term high-temperature heating is required and the resistance wire is not to be melted, the cross-section of the resistance wire needs to be increased. According to the conductive properties of the material, the cross-section of the resistance wire is inversely proportional to the resistance. When the cross-section of the resistance wire is increased, the resistance will become smaller, so that the current will increase during operation, resulting in a proportional increase in the heating power. Since it is difficult to use high-power heating when using a resistive heating stove at home, the food is heated slowly and unevenly.

[0047] See also Figure 1 to Figure 7 In one embodiment of the present invention, a thermal cycle arc cooker 100 is provided, comprising:

[0048] The stove body 10 has a heating chamber 11 formed inside thereof, and an arc generator 12 is arranged at the bottom thereof, and an arc generating end of the arc generator 12 is located in the heating chamber 11; a wind cavity 1211 is opened at the bottom of the arc generating end toward the circulation chamber 21, and at least one wind inlet hole 1212 is opened at the arc generating end corresponding to the wind cavity 1211, and the wind cavity 1211 is communicated with the heating chamber 11 through the wind inlet hole 1212;

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

[0050] At least one air guide duct 15, which connects the heating chamber 11 and the circulation chamber 21 to form an air outlet channel;

[0051] The fan 30 and the fan head 31 of the fan 30 are disposed in the wind cavity 1211 , the air outlet side of the fan head 31 is disposed close to the air inlet through hole 1212 , and the air inlet side of the fan head 31 is disposed close to the circulation chamber 21 .

[0052] In this embodiment, the electric arc stove 100 generates heat by using electric arc. The electric arc heating can generate a high temperature to heat food within a relatively small heating power (the total power is generally within 3500W). The electric arc stove includes a stove body 10, which can heat a heat-receiving body such as a cooker in contact with its heating chamber 11. An electric arc generator 12 is arranged on the stove body 10. The electric arc generator 12 is used to generate an electric arc, and the electric arc is generated at the electric arc generating end. The heat generated by the electric arc is conducted to the air in the heating chamber 11 through the electric arc generating end, and the air in the heating chamber 11 is heated. The bottom of the electric arc generating end is provided with an air cavity 1211 toward the circulation chamber 21. The fan head 31 is arranged in the air cavity 1211. When the fan 30 is working, the air in the circulation chamber 21 is sucked into the air inlet channel and then enters the heating chamber 11 through the air inlet through hole 1212. In this process, the air is fully and directly in contact with the electric arc generating end, so that it is quickly heated, and the heated air enters the heating chamber 11. When the fan 30 is working, since the air outlet side of the fan head 31 is arranged close to the air inlet hole 1212, and the air inlet side of the fan head 31 is arranged close to the circulation chamber 21, the air in the circulation chamber 21 is sucked into the heating chamber 11, so that the circulation chamber 21 is under negative pressure relative to the heating chamber 11, and the heated air in the heating chamber 11 enters the circulation chamber 21 through the air guide duct 15, thereby forming circulating wind. Optionally, four air guide ducts 15 are arranged and evenly distributed to speed up the circulation speed of the air in the heating chamber 11 and the circulation chamber 21. During the operation of the fan 30, the circulating wind is in direct contact with the arc generating end so as to be quickly heated. Under the action of the circulating wind, the heated body is not only heated quickly but also evenly, and the use of circulating wind for heating can save energy and reduce the energy consumption of electricity.

[0053] As an alternative embodiment, see Figure 1 to Figure 3 The air guide duct 15 is arranged 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 guide duct 15 extends toward the heating chamber 11 and extends to the top near the stove body 10, and the other end thereof extends toward the circulation chamber 21 and at least extends to the top near the circulation chamber shell 20.

[0054] In this embodiment, since the heated air in the heated chamber 11 rises upward, one end of the air guide duct 15 is extended to the top near the stove body 10 to guide the hot air at the top of the stove body 10 into the circulation chamber 21. Since the top of the circulation chamber housing 20 is closer to the wind chamber 1211, the other end of the air guide duct 15 is extended to the top near the circulation chamber housing 20. In addition, the air guide duct 15 is close to the top of the circulation chamber housing 20 but does not extend into the circulation chamber housing 20, which makes it more convenient to set the air guide duct 15. Of course, the other end of the air guide duct 15 can extend into the circulation chamber housing 20.

[0055] As an alternative embodiment, see Figure 1 to Figure 3 An opening 13 is provided on the top of the stove body 10 so that a heating object such as a cooker can cover the opening 13 and contact the heating chamber 11 .

[0056] As an alternative embodiment, see Figure 1 to Figure 3 The heat cycle arc cooker 100 also includes an electrical cavity shell, an electrical cavity is formed inside the electrical cavity, and a power supply component and a motor 32 of a fan 30 are arranged in the electrical cavity; 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 can be optionally connected to the lower part of the circulation cavity housing 20. The electrical cavity housing is used to install the power supply component and the motor 32 of the fan 30, etc. The power supply component can obtain power by installing a battery on the electrical cavity housing, or can be connected to an external power source through an external power line.

[0058] As an alternative embodiment, see Figure 1 to Figure 3 The electrical cavity housing includes an electrical cavity upper shell 41 and an electrical cavity lower shell 42. The first inner cavity 412 of the electrical cavity upper shell 41 and the second inner cavity 421 of the electrical cavity lower shell 42 form an electrical cavity chamber; the electrical cavity upper shell 41 is provided with a layered plate 411, and the layered plate 411 divides the first inner cavity 412 into an upper cavity 4121 and a lower cavity 4122, and the lower cavity 4122 is connected to the second inner cavity 421 of the electrical cavity lower shell 42;

[0059] The layered plate 411 is provided with a motor mounting groove 4111 communicating with the lower cavity 4122, and the motor mounting groove 4111 is protruding toward the upper cavity 4121; the circulation cavity housing 20 is provided with a through groove 22 adapted to the motor mounting groove 4111, the through groove 22 is extended toward 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 disposed in the motor mounting slot 4111 . A connecting rod 33 is connected between the motor 32 and the fan head 31 . An opening 4112 matching the connecting rod 33 is formed 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 set the motor installation groove 4111 to facilitate the installation of the motor 32. In order to facilitate the connection between the motor 32 and the fan head 31, a connecting rod 33 is set between the fan head 31 and the motor 32. The motor installation groove 4111 on the layered plate 411 is adapted to the through groove 22 on the circulation chamber housing 20, and the motor installation groove 4111 protrudes toward the upper cavity 4121, and the through groove 22 extends to the upper cavity 4121, so that the motor installation groove 4111 can close the through groove 22, which not only reduces the heat loss in the circulation chamber 21, but also avoids the heat in the circulation chamber 21 from being conducted to the electrical chamber to affect the operation of the power supply component and the motor 32.

[0062] As an alternative embodiment, see Figure 4 to Figure 7 The arc generator 12 includes a cathode conductive member 121, at least one electrode pair, at least one insulating heat-conducting tube 124, at least one conductive column 125 and at least one insulating heat-insulating tube 126;

[0063] At least one electrode installation hole 1213 is formed at the bottom of the cathode conductive member 121 toward the circulation chamber 21;

[0064] An electrode pair is installed inside each electrode installation hole 1213; the electrode pair includes a cathode ion head 122 and an anode ion head 123; the cathode ion head 122 is closely attached to the inside of the electrode installation hole 1213 and is arranged at one end away from the circulation chamber 21, and the cathode ion head 122 is electrically connected to the cathode conductive member 121;

[0065] The insulating heat-conducting tube 124 is of a hollow structure, and the anode ion head 123 corresponding to the cathode ion head 122 is arranged inside the insulating heat-conducting tube 124 and located at one end of the electrode mounting hole 1213 close to the circulation chamber 21; the insulating heat-conducting tube 124 is arranged close to the inside of the electrode mounting hole 1213, and there is a distance between the cathode ion head 122 and the anode ion head 123;

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

[0067] One end of the anode 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 column 125 is electrically connected to the power supply component.

[0069] In this embodiment, each electrode pair is respectively arranged inside each electrode mounting hole 1213 of the cathode conductive member 121, so that the arc generated between the electrode pairs is located inside the electrode mounting hole 1213, avoiding the user from contacting the arc. The cathode ion head 122 is close to the electrode mounting hole 1213, which can not only be electrically connected to the cathode ion head 122, but also directly conduct the heat of the cathode ion head 122 to the cathode conductive member 121. An insulating heat-conducting tube 124 is provided between the anode ion head 123 and the cathode conductive member 121, and optionally, the insulating heat-conducting tube 124 is a magnesium oxide tube. The insulating heat-conducting tube 124 avoids a short circuit between the anode ion head 123 and the cathode ion head 122, and can conduct the heat of the anode ion head 123 to the cathode conductive member 121. Optionally, one end of the insulating heat-conducting tube 124 abuts against the cathode ion head 122, and the other end is flush with the end face of the electrode mounting hole 1213. There is a distance between the cathode ion head 122 and the anode ion head 123 of the same electrode pair to facilitate the generation of an arc. The arc can release high temperature instantly, and the heat of the arc is conducted to the cathode conductive member 121 through the insulating heat-conducting tube 124. The anode ion head 123 is arranged close to the circulation chamber 21, so that the conductive column 125 connected to the anode ion head 123 can be conveniently extended from the electrode mounting hole 1213 and pass through the circulation chamber 21 to connect with the power supply component in the electrical chamber. The outer peripheral wall of the conductive column 125 is wrapped with an insulating heat-insulating tube 126 to avoid a short circuit between the conductive column 125 and the cathode conductive member 121, and at the same time reduce the conduction of heat between the conductive column 125 and the cathode conductive member 121. The insulating heat-insulating tube 126 can be selected as an alumina ceramic tube. The end of the cathode conductive member 121 close to the circulation chamber 21 can be conveniently electrically connected to the power supply component in the electrical chamber through a conductive wire. An air cavity 1211 is opened at the bottom of the cathode conductive part 121, and the fan head 31 of the fan 30 can be installed in the air cavity 1211. The blades of the fan head 31 rotate to suck the air in the circulation chamber 21 into the air cavity 1211 and then blow it into the heating chamber 11 through the air inlet hole 1212. The air is in direct contact with the cathode conductive part 121 and quickly obtains the heat of the cathode conductive part 121.

[0070] As an optional embodiment, the electrode mounting hole 1213 is a blind hole (non-through hole), which prevents the cathode ion head 122, the anode ion head 123 and the arc generated between the cathode ion head 122 and the anode ion head 123 from being exposed, thereby preventing users from contacting them.

[0071] See also Figure 7 The end of the cathode ion head 122 facing the anode ion head 123 is in an inverted cone shape; the end of the anode ion head 123 facing the cathode ion head 122 is in a cone shape; the cathode ion head 122 and the anode ion head 123 are discharged through the tip, so that the generated arc can be stable.

[0072] See also Figure 1 and Figure 3 The bottom of the stove body 10 is provided with a limit ring 14 protruding toward the heating chamber 11, and the bottom of the cathode conductive member 121 is provided with a limit groove 1214 adapted to the limit ring 14, and the limit groove 1214 is inserted into the limit ring 14. The cathode conductive member 121 is fixed on the stove body 10 by the cooperation of the limit ring 14 and the limit groove 1214.

[0073] As an alternative embodiment, see Figures 4 to 6 There are multiple pairs of electrode pairs, and multiple electrode mounting holes 1213 are opened corresponding to the electrode pairs; the multiple electrode mounting holes 1213 form a ring and are arranged around the outer periphery of the wind cavity 1211, so that the heat generated by the multiple arc pairs can be more quickly conducted to the air inlet channel and the cathode conductive member 121 around the air inlet channel. When the fan 30 is working, the air entering the air inlet channel can be quickly heated.

[0080] As an optional embodiment, the cathode conductive member 121 is made of a metal material, and the cathode conductive member 121 is in a truncated cone, a cylindrical shape, or a hemispherical shape.

[0081] The working process of the thermal cycle arc cooker 100 is as follows:

[0082] A heat receiving body such as a pot is placed on the top of the stove body 10 so that the pot is in contact with its heat receiving chamber 11, and food is placed on the pot; the circuit board 51 is connected to an external power source through an external power line and powered on, and the anode current of the circuit board 51 is introduced into the anode ion head 123 through the anode wire 52, the shunt circuit board 53, and the conductive column 125. At the same time, the cathode current of the circuit board 51 is introduced into the cathode ion head 122 through the cathode wire 54 and the cathode conductive member 121. Due to the distance between the cathode ion head 122 and the anode ion head 123, an arc is finally generated, and the arc quickly releases high temperature; the high temperature generated by the cathode ion head 122 is directly introduced into the cathode conductive member 121, The high temperature generated by the anode ion head 123 and the arc is introduced to the cathode conductive member 121 through the insulating heat-conducting pipe 124; the insulating heat-conducting pipe 124 is a magnesium oxide tube, which not only has a heat-conducting effect but also has insulation properties; after heating for a preset 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 wind, that is, air is sucked into the heating chamber 11 through the air inlet channel from the circulation chamber 21. In this process, the air contacts the cathode conductive member 121 and is quickly heated. The hot air rises after entering the heating chamber 11. Since the circulation chamber 21 is under negative pressure relative to the heating chamber 11, the hot air enters the circulation chamber 21 through the four air-conducting ducts 15. Since the circulating wind is quickly heated, the pot body quickly obtains heat to heat the food.

[0083] In summary, the heat circulation electric arc stove of the present invention can generate high temperature with relatively small heating power by utilizing the heating characteristics of electric arc. Specifically, the electric arc stove includes a stove body, a circulation chamber shell, an air guide duct and a fan. A heating chamber is formed inside the stove body, an arc generator is arranged at the bottom thereof, and the arc generating end of the arc generator is located in the heating chamber; a wind chamber is opened at the bottom of the arc generating end toward the circulation chamber, and at least one wind inlet hole is opened at the arc generating end corresponding to the wind chamber, and the wind chamber is connected with the heating chamber through the wind inlet hole; since the arc generating end of the arc generator is located in the heating chamber, the air in the heating chamber is heated. The circulation chamber shell is arranged on the outer side of the bottom of the stove body, and the circulation chamber is formed between the circulation chamber and the stove body, and the circulation chamber is connected with the wind chamber to form an air inlet channel; after the arc generator heats the air in the heating chamber to a preset temperature, the fan starts to work, and the fan head of the fan is arranged in the wind chamber, the air outlet side of the fan head is arranged close to the air inlet through hole, and the air inlet side of the fan head is arranged close to the circulation chamber, so that when the fan starts to work, the air in the circulation chamber is sucked into the air inlet channel and then enters the heating chamber through the air inlet through hole. In this process, the air comes into contact with the high temperature of the arc generating end, thereby being quickly heated; at the same time, since at least one air duct is connected to the heating chamber and the circulation chamber to form an air outlet channel, when the fan is working, the air heated by the heating chamber enters the circulation chamber through the air duct, thereby forming circulating wind. The circulating wind circulates and directly contacts the arc generating end to be quickly heated, and the heated body contacts the heating chamber. Under the action of the circulating wind, the heated body is not only heated quickly but also evenly. The use of circulating wind for heating can save energy and reduce electrical energy consumption.

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