Description

Technical Field

[0001] The invention relates to the technical field of steam furnaces, and in particular to an arc steam furnace. Background Art

[0002] The steam boiler in the prior art generates steam through a steam generator. The steam generator generates steam by first adding a certain amount of cold water into the water storage heating chamber, and then heating the water in the heating chamber through a heating system. When heated to 100 degrees or above, steam is generated. However, the heating system of the steam generator in the prior art adopts resistive heating technology. There is a characteristic when 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 metal materials, 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 becomes larger during operation, resulting in a proportional increase in the heating power. If the current is to be controlled, the length of the resistance wire needs to be lengthened, and it is difficult to convert high-power heat in a small volume. Therefore, the existing method of generating steam has the following disadvantages: first, the speed at which the water in the heating chamber is heated to 100 degrees by resistive heating is slow, so the speed of generating steam is slow; second, due to the slow heating speed, a certain amount of water needs to be added to the heating chamber first. If the water in the heating chamber is not used up when generating steam, the energy used to heat the water will be wasted; third: the steam furnace needs to generate high-temperature steam quickly, but the resistive heating in the existing technology is difficult to generate high-temperature steam efficiently. If a large or multi-stage heating system is used to heat a high-power device, the cost is too high and the volume is large.

[0003] In summary, the existing structure has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the invention

[0047] See also Figures 1 to 9 In one embodiment of the present invention, an arc steam furnace 100 is provided, comprising:

[0048] Steamer support 10;

[0049] A steamer 20 is disposed above the steamer support 10;

[0050] The steam generator 30 includes at least one arc generator 31, a heat exchanger 32, a water inlet pipe 33 and an air outlet pipe 34; the arc generator 31 is arranged in the lateral direction of the heat exchanger 32, and a group of water heating pipe groups are arranged along the longitudinal direction of the heat exchanger 32, and the water heating pipe group is arranged around the head end of the arc generator 31; one end of the water inlet pipe 33 is connected to an external water source, and the other end is connected to the water inlet end 3216 of the water heating pipe group; one end of the air outlet pipe 34 is connected to the steam outlet end 3217 of the water heating pipe group, and the other end discharges the steam generated by the arc generator 31 heating the water in the water heating pipe group into the steamer 20.

[0051] In this embodiment, the arc steam oven 100 can use electric energy to generate an arc, and the arc instantly releases high temperature to quickly generate steam and steam the food in the steamer 20. Specifically, the steamer support 10 is used to support the steamer 20, and the steamer 20 is used to load food. The steamer 20 can be separated from the steamer support 10, and the steam generator 30 can quickly generate steam, and the steam enters the steamer 20 to steam the food. The steam generator 30 is optionally arranged on the outer side of the steamer support 10. The steam generator 30 generates heat by generating an arc through the arc generator 31. Since the arc can generate high temperature instantly, and quickly transfer the heat to the water heating pipe group through the heat exchange body 32, the water heating pipe group can be formed by the channels opened inside the heat exchange body 32. The heat generated by the arc generator 31 is transferred to the heat exchange body 32 so that the water heating pipe group is quickly heated to more than 300 degrees. When the external water source enters the water heating pipe group through the water inlet pipe 33, the external water source contacts the high-temperature water heating pipe group to quickly generate steam, and the steam is discharged to the steamer 20 through the exhaust pipe 34. Specifically, the arc is generated at the head end of the arc generator 31, and the head end of the arc generator 31 directly contacts the heat exchange body 32. At least one arc generator 31 is disposed at one end of the heat exchange body 32 in the transverse direction. When there are multiple arc generators 31, the multiple arc generators 31 are arranged in sequence at a certain distance in the longitudinal direction and are all disposed at the same end in the transverse direction of the heat exchange body 32. For example, when the heat exchange body 32 is in the shape of a prism, one side surface of the prism is used as the same end in the transverse direction, and the multiple arc generators 31 are evenly distributed on one side surface of the prism in the longitudinal direction (see Figure 3 ). And each water heating pipe in the water heating pipe group is arranged along the longitudinal direction of the heat exchange body 32, so that the water heating pipe is heated evenly and heats up quickly. Optionally, the heat exchange body 32 is prismatic to facilitate the arrangement of the arc generator 31 and the water heating pipe group. Optionally, each water heating pipe in the water heating pipe group is respectively located on the periphery of the head end of the arc generator 31, and each water heating pipe is equidistant from the head end of the arc generator 31, so that each water heating pipe not only heats up quickly but also has the same heating rate, thereby avoiding the impact of steam generation due to the slow heating rate of one or more of the water heating pipes. The water inlet pipe 33 is connected to an external water source. When the water heating pipe group is heated to a preset temperature, the water inlet pipe 33 can be opened. There is no need to store water in the water heating pipe group. When enough steam is generated, the water inlet pipe 33 is closed, and the steam generator 30 stops working to avoid energy waste.

[0052] As an alternative embodiment, see Figure 1-2 A vent 11 is provided on the top of the steamer support 10, and a first inner cavity 12 is formed inside the steamer support 10, and the vent 11 is connected to the first inner cavity 12;

[0053] The steamer 20 covers the vent 11, and a plurality of vent holes 21 are formed at the bottom of the steamer 20. A second inner cavity 22 is formed inside the steamer 20, and the vent holes 21 are connected to the second inner cavity 22.

[0054] The first inner cavity 12 and the second inner cavity 22 form a steam cavity, and the top cover of the steamer 20 is provided with a steamer cover 23, and the steamer cover 23 closes the steam cavity;

[0055] The gas outlet pipe 34 of the steam generator 30 is in communication with the steam chamber.

[0056] In this embodiment, the second inner cavity 22 of the steamer 20 is used to place food. The steamer 20 is located above the vent 11. Optionally, the steamer 20 is located directly above the vent 11. The steam generated by the steam generator 30 enters the first inner cavity 12 and passes upward through the vent 11 and the vent hole 21 before entering the second inner cavity 22 to steam the food. The steamer cover 23 closes the steam cavity to reduce the overflow of steam and avoid affecting the speed of steaming the food.

[0057] As an alternative embodiment, see Figure 1-2 The electric arc steam furnace 100 further includes a steam dispersion pipe 40, which is disposed in the first inner cavity 12 and is located below the vent 11; a first end 41 of the steam dispersion pipe 40 is connected to the gas outlet pipe 34; a second end 42 of the steam dispersion pipe 40 is disposed corresponding to the vent 11, and a plurality of exhaust holes 421 are formed on a side of the second end 42 facing the vent 11, and each exhaust hole 421 is evenly dispersed on the second end 42; the first end 41 is connected to the second end 42;

[0058] A plurality of ventilation holes 21 are evenly distributed at the bottom of the steamer 20;

[0059] The steam generator 30 is disposed on the outer side of the steamer support 10 .

[0060] In this embodiment, in order to heat the food in the steamer 20 evenly, a steam dispersion pipe 40 is arranged in the first inner cavity 12, and the steam is uniformly ejected through the exhaust holes 421 of the steam dispersion pipe 40, and then uniformly enters the second inner cavity 22 of the steamer 20 through the uniformly arranged vent holes 21. The second end 42 of the steam dispersion pipe 40 is arranged corresponding to the vent 11. For example, when the vent 11 is circular, the second end 42 is arranged in a ring or disc shape. When the vent 11 is square, the second end 42 is arranged in a square shape, so that the steam is uniformly dispersed and the ejected steam is uniformly passed through the vent 11 into the steamer 20 to steam the food.

[0061] As an alternative embodiment, see Figure 3-4 , the water heating pipeline group includes three water heating pipelines arranged in parallel and two guide pipes;

[0062] The guide pipe is curved and has two head ends; the three water heating pipes are respectively a first water heating pipe 3211, a second water heating pipe 3212 and a third water heating pipe 3213; the two guide pipes are respectively a first guide pipe 3214 and a second guide pipe 3215;

[0063] The head ends of the third water heating pipe 3213 and the second water heating pipe 3212 are both connected to the first guide pipe 3214, and the tail ends of the second water heating pipe 3212 and the first water heating pipe 3211 are both connected to the second guide pipe 3215; the tail end of the third water heating pipe 3213 is the steam outlet end 3217, and the head end of the first water heating pipe 3211 is the water inlet end 3216.

[0064] In this embodiment, a plurality of water heating pipes are arranged in parallel, and the water heating pipes are connected to each other through guide pipes so that each water heating pipe is connected from the water inlet end 3216 to the steam outlet end 3217 .

[0065] As an alternative embodiment, see Figure 3-4 The heat exchange body 32 is prismatic to facilitate the installation of the arc generator 31 and the water heating pipe group; the heat exchange body 32 is provided with a mounting hole 322 on the end face of one end in the horizontal direction, and the mounting hole 322 is a blind hole. The arc generator 31 is installed in the mounting hole 322, and the arc generator 31 can be stably installed on the heat exchange body 32 when installed in the blind hole; the water heating pipe group passes through the heat exchange body 32 in the longitudinal direction, and each water heating pipe can be connected through a guide pipe located outside the heat exchange body 32, and the guide pipe is welded to the water heating pipe. The outer peripheral wall of the heat exchange body 32 is wrapped with a matching heat insulation layer 323, which is used to reduce the heat conduction of the heat exchange body 32 to the outside, which not only avoids the heat loss of the heat exchange body 32, but also protects the external components of the heat exchange body 32.

[0066] As an alternative embodiment, see Figure 3-4 The mounting holes 322 and the arc generator 31 each include a plurality of mounting holes 322, which are arranged at a predetermined distance in the longitudinal direction; that is, a plurality of mounting holes 322 are provided on the end surface of one lateral end of the heat exchange body 32, and the mounting holes 322 are evenly distributed in the longitudinal direction so that when the arc generators 31 respectively installed in the mounting holes 322 simultaneously conduct heat to the water heating pipe that passes through the longitudinal direction, each position on the water heating pipe is heated evenly. The plurality of arc generators 31 are respectively installed in the plurality of mounting holes 322, and the plurality of arc generators 31 generate arcs at the same time, which can increase the temperature rise rate of the water heating pipe, thereby increasing the steam generation rate.

[0067] As an alternative embodiment, see Figure 5 to Figure 7 , the arc generator 31 includes a cathode 311 and an anode 312;

[0068] The cathode 311 is disposed at the bottom of the mounting hole 322, and the cathode 311 is electrically connected to the heat exchange body 32;

[0069] The anode 312 is arranged in the mounting hole 322 through the insulating heat-conducting tube 313, and is located above the cathode 311; the interior of the insulating heat-conducting tube 313 is a hollow pipe, and the lower part of the hollow pipe is protruding inward and provided with a boss 314; the anode 312 is arranged in the hollow pipe, and the edge of the bottom end of the anode 312 abuts against the boss 314; the top end of the anode 312 is electrically connected to the conductive column 315, and the outer peripheral wall of the conductive column 315 is wrapped with an insulating heat-insulating tube 316.

[0070] In this embodiment, the cathode 311 is electrically connected to the heat exchange body 32, and the cathode 311 is arranged in close proximity to the heat exchange body 32 in the mounting hole 322, so that when multiple cathodes 311 are provided, multiple cathodes 311 can be conveniently powered simultaneously through the heat exchange body 32. The anode 312 is arranged in the mounting hole 322 through the insulating heat-conducting tube 313, so that a short circuit between the anode 312 and the cathode 311 is avoided, and the heat generated by the anode 312 can be conducted to the heat exchange body 32. The arrangement of the boss 314 defines a spacing between the anode 312 and the cathode 311, so that an arc is generated between the anode 312 and the cathode 311 when a certain voltage difference is formed between the anode 312 and the cathode 311. The anode 312 is energized through the conductive column 315. In order to avoid a short circuit between the conductive column 315 and the heat exchange body 32, the outer peripheral wall of the conductive column 315 is wrapped with an insulating tube. Since heat exchange is not required between the conductive column 315 and the heat exchange body 32, the insulating tube is set to be an insulating heat-insulating tube 316 with a lower thermal conductivity, and the thermal conductivity of the insulating heat-insulating tube 316 is lower than that of the insulating heat-conducting tube 313. Specifically, the insulating heat-conducting tube 313 is a magnesium oxide tube, and the insulating heat-insulating tube 316 is an aluminum oxide tube.

[0071] As an optional embodiment, the heat exchange body 32 is made of metal material to facilitate heat conduction; the anode 312 is made of tungsten alloy material; the cathode 311 is made of tungsten alloy material, and the anode 312 and cathode 311 made of tungsten alloy material have high temperature resistance characteristics; the top of the cathode 311 protrudes toward the anode 312 to form a cone (see Figure 7 ); The bottom end of the anode 312 protrudes toward the cathode 311 to form a cone (see Figure 7 ), since the cone has a pointed end, a stable discharge can be generated between the anode 312 and the cathode 311 to generate an arc.

[0072] As an alternative embodiment, see Fig. 9 The steam generator 30 further includes a power supply component electrically connected to the arc generator 31; the power supply component includes:

[0073] A circuit board 351, on which an anode current circuit and a cathode current circuit are arranged;

[0074] An anode wire 352, 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 353;

[0075] A shunt circuit board 353 electrically connected to the conductive pillar 315;

[0076] One end of the cathode wire 354 is electrically connected to the cathode current circuit, and the other end is electrically connected to the heat exchanger 32 .

[0077] In this embodiment, the circuit board 351 is connected to an external power source through an external power line and powered on, and current enters the circuit board 351. The anode current formed by the anode current circuit on the circuit board 351 is connected to the shunt circuit board 353 through the anode wire 352. The shunt circuit board 353 can supply power to multiple conductive pillars 315 at the same time. The shunt circuit board 353 may be optionally provided with multiple through holes adapted to the conductive pillars 315. Each conductive pillar 315 is installed in each through hole and electrically connected to the shunt circuit board 353. The cathode current formed by the cathode current circuit on the circuit board 351 is electrically connected to the heat exchange body 32 through the cathode wire 354.

[0078] As an alternative embodiment, see Figure 8-Figure 9 The steam generator 30 further includes a shell body 36, which includes a surface shell 361 and a bottom shell 362. A device cavity 363 is formed between the surface shell 361 and the bottom shell 362, and the heat exchange body 32 is installed in the device cavity 363. The shell body 36 can protect the heat exchange body 32 disposed therein, and can also protect the user. The water inlet pipe 33 and the air outlet pipe 34 connected to the heat exchange body 32 can extend from the shell body 36. Of course, the power supply component can also be disposed in the device cavity 363, and a heat insulation board can be optionally disposed between the power supply component and the heat exchange body 32.

[0079] The working process of the arc steam furnace 100 is as follows:

[0080] The steam generator 30 is connected to an external power source through an external power cord and powered on, and the current enters the circuit board 351; the anode current on the circuit board 351 reaches the anode 312 through the anode wire 352, the shunt circuit board 353, and the conductive column 315, and at the same time, the cathode current on the circuit board 351 flows from the cathode wire 354 and the heat exchanger 32 to the cathode 311, and an arc is generated between the cathode 311 and the anode 312, and the arc releases a large amount of heat; part of the heat is transferred to the heat exchanger 32 through the cathode 311, and the other part is transferred to the heat exchanger 32 through the magnesium oxide tube, and the heat exchanger 32 is quickly heated to a temperature of 100°C. When the temperature reaches above 300 degrees, the water inlet pipe 33 is opened, and external tap water enters the water heating pipe group of the heat exchanger 32 through the water inlet pipe 33. The water heating pipe group is formed by the channels opened inside the heat exchanger 32. The tap water contacts the high-temperature water heating pipe group inside the heat exchanger 32, and steam is quickly generated. The steam is ejected through the air outlet pipe 3440 and enters the steam dispersion pipe 40. The steam is then discharged into the first inner cavity 12 through the multiple exhaust holes 421 on the steam dispersion pipe 40. The steam in the first inner cavity 12 then enters the second inner cavity 22 through the vent holes 21 at the bottom of the steamer 20 to steam the food.

[0081] In summary, the electric arc steam oven of the present invention comprises a steamer support, a steamer and a steam generator, wherein the steamer support is used to support the steamer, the steam generator can be optionally installed on the steamer support, the steamer is used to carry food, and the steam generator generates steam to steam the food in the steamer. Specifically, the steamer is arranged above the steamer support, and the steamer can be separated from the steamer support; the steam generator comprises at least one electric arc generator, a heat exchange body, a water inlet pipe and an air outlet pipe. The heat exchanger is used to transfer the heat generated by the arc generator to the water heating pipe inside it. The arc generator is arranged in the horizontal direction of the heat exchanger, and a group of water heating pipes is arranged in the longitudinal direction; and the group of water heating pipes is arranged around the head end of the arc generator; one end of the water inlet pipe is connected to an external water source, and the other end is connected to the water inlet end of the water heating pipe group; one end of the air outlet pipe is connected to the steam outlet end of the water heating pipe group, and the other end discharges the steam generated by the arc generator heating the water in the water heating pipe group. Since the arc generator can instantly generate a high temperature of more than 1000 degrees and transfer it to the water heating pipe through the heat exchanger, the water heating pipe can be quickly heated to more than 300 degrees. At this time, the external water source enters the water heating pipe through the water inlet pipe and quickly forms steam and is discharged from the air outlet pipe. There is no need to store water in the water heating pipe. When enough steam is generated, the water inlet pipe can be closed to save energy.

[0082] 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.
