Description

Technical Field

[0001] The invention relates to the technical field of cookers, and in particular to an arc generator component for an arc cooker and the arc cooker. Background Art

[0002] Existing electric arc stoves usually have several arc emitting heads such as ion heads / ion needles for generating ion flames in the furnace head. High voltage electricity breaks through the air to form thermal plasma, thereby converting electrical energy into thermal energy, generating a flame-like thermal plasma beam to heat the pots placed on the pot ring.

[0003] However, the existing arc stoves still have the following problems: the arc emitter head is exposed on the stove head. If soup overflows and splashes onto the emitter head during cooking, it is easy to cause conductivity and cause electric shock; the arc emitter head adopts sharp point discharge, which is easy to cause the emitter head to melt and carbonize after long-term use, making the arc emitter head unable to be used for a long time and requiring maintenance and replacement; the existing arc stoves are usually equipped with more than 10 arc emitters, the structure is relatively complex, and the cost of replicating production is high.

[0004] Therefore, there is an urgent need for an electric arc stove that can avoid the situation of conductive injury to people and can extend the service life of the electric arc stove. Summary of the invention

DETAILED DESCRIPTION

[0044] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below in conjunction with the accompanying drawings through specific embodiments. Figure 2 The orientation is used as a reference.

[0045] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0046] See also Figure 1-5The present invention provides an arc stove, including an arc generator assembly, a burner bracket 14 and a shell. The arc generator assembly is arranged in the shell, and the burner bracket 14 is arranged on the top of the shell corresponding to the arc generator assembly. The top of the arc generator assembly is covered with an arc insulating sheet 16 to isolate the arc generator assembly from discharging to the bottom of the pot, making it safer for the operator to use.

[0047] The housing includes an upper housing 12 and a lower housing 13, which are fixedly connected to form an electronic device cavity 11 between the upper housing 12 and the lower housing 13. The upper housing 12 has an air cavity 121 for accommodating the arc generator assembly, and a circular through hole is opened on the upper surface of the upper housing 12 corresponding to the air cavity 121.

[0048] The arc generator assembly includes: an annular body 15 , an arc insulating sheet 16 , an arc generator 17 , an arc generator heat insulating sheet 18 , a cyclone assembly, a magnet 21 and a conductive column 23 .

[0049] The ring body 15 is in a circular shape, and a coaxial through hole is provided in the middle of the ring body 15. An arc guide 153 with an annular flange structure is provided at the edge of the through hole to guide the arc. The arc guide 153 is connected to the ground wire. The ring body 15 is placed at the circular through hole on the upper shell 12, and the arc guide 153 is placed in the circular through hole accordingly.

[0050] A furnace head heat insulating sheet 19 is also provided between the bottom outer edge of the annular body 15 and the upper shell 12 for heat insulation.

[0051] The arc generator 17 is coaxially arranged in the through hole of the annular body 15 corresponding to the arc guide 153, and there is a gap for generating an arc between the arc generator 17 and the arc guide 153 of the annular body 15, so that the circumferential outer edge of the arc generator 17 is used as the generating point of the arc, and the circumferential inner edge of the arc guide 153 is used as the receiving point of the arc, so as to generate an arc between the arc generator 17 and the arc guide 153. The conductive column 23 is arranged at the bottom of the arc generator 17, and is used to provide electrical connection to the arc generator 17.

[0052] The arc insulating sheet 16 and the arc generator 17 are disc-shaped, and the arc insulating sheet 16 covers the top surface of the arc generator 17 and is fixedly connected to the arc generator 17. The size of the arc insulating sheet 16 is larger than the arc generator 17, and there is a gap between the arc insulating sheet 16 and the arc guide 153.

[0053] Since the upper surface of the arc generator 17 is completely covered by the arc insulating sheet 16, the arc generator 17 will not discharge to the bottom of the pot, isolating the possibility of conduction. When water is splashed on the arc generator 17, the arc insulating sheet 16 can also be waterproof and guide the water into the air cavity 121, and the water is discharged through the water leakage valve 24 at the bottom of the air cavity 121, effectively preventing the occurrence of electric shock and leakage.

[0054] The arc generator heat shield 18 is fixed to the bottom of the arc generator 17 and has a through hole for the conductive column 23 to pass through. The bottom of the arc generator heat shield 18 is in the same horizontal plane as the bottom of the arc guide 153, and the horizontal cross-sectional size of the arc generator heat shield 18 is less than or equal to the size of the arc generator 17 to avoid obstructing the flow of the cyclone.

[0055] A mounting seat 122 is provided at the bottom of the air cavity 121 . A columnar slot 123 for passing the conductive column 23 is provided in the middle of the mounting seat 122 . The slot 123 is communicated with the electronic device cavity 11 .

[0056] The cyclone assembly includes: a cyclone generator 20 and a blower 25. The cyclone generator 20 is coaxially arranged at the bottom of the annular body 15 and the arc generator 17. The cyclone generator 20 is annular, and a through hole for passing the conductive column 23 is provided in the middle of the cyclone generator 20. A plurality of air guide blades 201 are provided along the circumferential direction of the cyclone generator 20 to guide the wind direction so that a cyclone can be formed in the wind cavity 121.

[0057] The arc insulating sheet 16 , the arc generator 17 , the arc generator heat insulating sheet 18 and the cyclone generator 20 are arranged in the wind cavity 121 in sequence from top to bottom.

[0058] The blower 25 is fixed in the electronic device cavity 11, and an air inlet interface 251 is provided on the side wall of the wind cavity 121. The air inlet interface 251 is correspondingly arranged on one side of the cyclone generator 20. The blower 25 is connected to the wind cavity 121 through the air inlet interface 251. The air inlet interface 251 is tangent to the arc-shaped side wall of the wind cavity 121, so that the wind blown into the air inlet interface 251 by the blower 25 can flow along the arc-shaped side wall of the wind cavity 121 from the air inlet interface 251, and form a cyclone through the cyclone generator 20, blowing the arc out from the gap between the arc generator 17 and the annular body 15, so that the heat generated by the arc can be effectively blown to the bottom of the pot for heating, and the arc can be made to look like a flame.

[0059] The magnet 21 is in a circular shape and is located below the cyclone generator 20. The arc generated by the arc generator 17 is affected by the Lorentz force in the magnetic field of the magnet 21 and is constrained by the circular magnet 21. Under the action of the magnet 21 and the cyclone generator 20, the arc moves circumferentially along the arc generator 17 and releases heat, thereby forming a heating surface and expanding the heating area. At the same time, since the arc generator 13 is no longer a sharp point, the service life of the arc generator 13 is extended.

[0060] A limiting plate 124 is circumferentially arranged on the outer side of the mounting seat 122 , and a mounting groove is formed between the limiting plate 124 and the mounting seat 122 , and the magnet 21 is fixedly arranged in the mounting groove.

[0061] The outer side of the conductive column 23 is wrapped with a conductive column insulating sleeve 22, and the top of the conductive column 23 passes through the slot 123, the cyclone generator 20, the arc generator heat insulation sheet 18 from bottom to top in the electronic device cavity 11 and is electrically connected to the bottom surface of the arc generator 17.

[0062] The centers of the arc insulating sheet 16 , the arc generator 17 , the arc generator heat insulating sheet 18 , the cyclone generator 20 , the conductive column 23 and the magnet 21 are all located on the same axis.

[0063] The burner bracket 14 is detachably fixed on the annular body 15 to form a heating chamber with the annular body 15 . The burner bracket 14 is a hollow columnar structure. The diameter of the first end of the burner bracket 14 is greater than the diameter of the second end.

[0064] The top surface of the annular body 15 is provided with an annular groove along the circumferential direction, and the annular groove has a first side wall 151 and a second side wall 152. The diameter of the first side wall 151 corresponds to the outer diameter of the first end of the burner bracket 14, and the diameter of the second side wall 152 corresponds to the inner diameter of the second end of the burner bracket 14, so that the burner bracket 14 can be fixed by the annular body 15 whether the first end or the second end is facing downward. If a larger pot is used, the first end of the burner bracket 14 is set upward, and the second end is fixed to the annular body 15 downward. If a smaller pot is used, the second end of the burner bracket 14 is set upward, and the first end is fixed to the annular body 15 downward. By setting the burner bracket 14 with different sizes at both ends, the applicability of the burner bracket 14 to the pot size is improved.

[0065] The arc range also includes a circuit board 26, a step-up transformer 28 and a cooling fan 29 fixed in the electronic device cavity 11. The circuit board 26 is connected to an external power source through a power line 30. The conductive column 23, the step-up transformer 28 and the circuit board 26 are connected in sequence to supply power to the conductive column 23. The cooling fan 29 is used to dissipate heat for the electronic device cavity 11. The blower 25 and the cooling fan 29 are connected to the circuit board 26 to supply power to the blower 25 and the cooling fan 29 respectively.

[0066] A panel 1 is provided on the upper surface of the upper shell 12 , and a knob switch 27 and buttons for controlling the arc range are provided on the panel 1 .

[0067] A water collecting tank 241 is also provided at the bottom of the air cavity 121. A water leakage valve 24 is fixed to the bottom of the water collecting tank 241 using soft material to block the water leakage hole leading to the outside. When drainage is required, the water leakage valve 24 is opened to discharge the water in the water collecting tank 241 through the water leakage hole.

[0068] The present invention provides an arc cooker, wherein the arc generator 17 is covered with an arc insulating sheet 16 so that the arc generator 17 does not discharge to the bottom of the cooker, thereby isolating the possibility of conduction. When water is splashed onto the arc generator 17, the arc insulating sheet 16 can also be waterproof and guide the water into the air cavity 121.

[0069] By combining the cyclone generator 20, the magnet 21 and the arc generator 17, the arc generated by the arc generator 17 is affected by the magnetic field, moves circumferentially along the arc generator 17, and releases heat, thereby forming a heating surface and expanding the heating area. At the same time, since the arc generator 13 is no longer a sharp point, the service life of the arc generator 13 is extended.

[0070] By combining the cyclone generator 20 and the blower 25, the wind blown into the wind chamber 121 by the blower 25 forms a cyclone under the action of the cyclone generator 20, so as to blow the arc out from the gap between the arc generator 17 and the annular body 15, so that the heat generated by the arc can be blown to the bottom of the pot for heating, and the arc can look like a flame.
