Description

Technical Field

[0001] The present invention relates to the technical field of steam appliances, and more specifically to a high-frequency electromagnetic plunger steam generator. Background Art

[0002] Steam generator is a mechanical device that uses the thermal energy of fuel or other energy to heat water into hot water or steam. Steam generators can be divided into electric steam generators, oil steam generators, gas steam generators, etc. according to fuel classification. Steam generators are mainly suitable for garment factories, dry cleaners, restaurants, steamed bun shops, canteens, restaurants, factories, mines, bean product factories and other places.

[0003] Steam generators can be classified into instant steam generators and boiler steam generators according to their size. Instant steam generators are small devices mainly used in daily life, while boiler steam generators are generally used in industrial production, such as thermal power plants, ships, locomotives, and industrial and mining enterprises. Instant steam generators use direct current steam generation technology, which allows tap water to generate steam instantly after heat exchange, achieving the beneficial effects of instant heating without preheating, safety and convenience.

[0004] With the development of science and technology, instant steam generators are more and more widely used in people's lives, and people's requirements for instant steam generators are getting higher and higher. However, the steam generated by existing instant steam generators has low temperature and low dryness; the thermal energy utilization is insufficient, the heating and steaming efficiency is low, the vaporization effect is not ideal, and it is not convenient to use and cannot meet people's requirements. Therefore, the structure of the existing instant steam generator is in urgent need of improvement.

[0005] On the other hand, after using the existing steam generator for a period of time, the impurities in the water are converted into scale after the water is heated, and the scale adheres to the internal flow channel and steam outlet of the steam generator. In the long run, most of the surface of the heating body is covered with scale, which affects the heat transfer effect and increases the energy consumption of the steam generator. At present, due to the unreasonable structural design of the steam generator, the internal cavity space is small, and the scale easily fills the cavity. The blockage of scale will affect the function of the steam generator, and in serious cases, there may be a risk of explosion. Summary of the invention

[0006] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide a high-frequency electromagnetic plunger steam generator with fast heating efficiency, large steam output capacity, high temperature and certain pressure, and safety and reliability.

[0007] The technical solution adopted by the present invention is: a high-frequency electromagnetic plunger steam generator, including a main valve core, a water inlet is provided at the bottom of the main valve core, and a steam outlet is provided at the top; wherein, the main valve core includes an outer core and an inner core, the outer core is a hollow structure, the inner core is arranged in the hollow structure of the outer core, and a chamber for water flow is reserved between the outer core and the inner core; a high-frequency sudden current generating coil is provided on the outer wall of the outer core, the high-frequency sudden current generating coil is electrically connected to an external steam generator mainboard, and generates an alternating electric field to act on the outer core, and according to the eddy current principle, the main valve core heats up rapidly, so that the temperature in the chamber increases, water flows in from the water inlet, is heated and evaporated into water vapor when passing through the chamber, and then flows out from the steam outlet.

[0008] This technical solution mainly utilizes the principle of eddy current, with the outer core as a conductor. The external steam generator mainboard is connected to the high-frequency alternating current generating coil and resonates with the outer core, thereby generating an alternating electric field acting on the outer core, causing the main valve core itself to heat up rapidly, and the fluid flows through the chamber between the outer core and the inner core, thereby achieving the purpose of heating the fluid.

[0009] Since the eddy current phenomenon generates a lot of heat, the water entering the chamber can quickly heat up and quickly produce saturated steam. At the same time, the use of high-frequency electromagnetic heating allows the inner and outer cores to self-heat instead of heat transfer, and the self-heating temperature rises quickly, thereby effectively increasing the steam saturation.

[0010] The inner core of the technical solution is arranged in the hollow structure of the outer core, so that the entire generator is a cavity structure, which can reasonably distribute water resources and ensure the activity of water molecules in the cavity; at the same time, the fluid flow direction of the cavity structure is single, which relaxes the restrictions on the installation method of the generator, so that the installation method of the generator can be installed and allocated according to different needs. On the other hand, since the inner core is arranged in the hollow structure of the outer core as a detachable structure, it is conducive to maintenance and adjustment of parameters, and there is a huge upgrade space. At the same time, due to the small size of the generator, it also has the beneficial effect of being easy to maintain and carry.

[0011] The inner core structure of the present technical solution is streamlined in design, which is more in line with the principles of fluid mechanics and can prevent the generator from generating irresistible danger and gas output due to scale blockage or other reasons.

[0012] The high-frequency electromagnetic heating of this technical solution uses the principle of electromagnetic induction to convert electrical energy into magnetic heat energy, so that the metal container can heat up quickly by itself. Compared with the traditional gas heating technology, it has the advantages of water-electricity separation, rapid heating and energy saving. Compared with resistance wire heating, the electromagnetic steam generator has faster heating efficiency, saves electricity, time and money. The electromagnetic steam generator adopts electromagnetic heating technology. There is an insulator between the wire and the furnace body. It relies on the collision heating of the magnetic field and iron to effectively avoid leakage accidents.

[0013] The technical solution adopts a plunger-type injection of fluid, and the fluid can only move in one direction, so there is no restriction on the installation method of the generator.

[0014] The steam generator of this technical solution has strong power scalability and can operate in any power range between 500W-100KW.

[0015] Furthermore, a hollow fluid distribution chamber is provided in the lower half of the inner core, and a fluid distribution port is provided on the bottom side wall of the fluid distribution chamber; the fluid distribution port is connected to the chamber, and the fluid distribution chamber is connected to the water inlet. After the external water enters the fluid distribution chamber from the water inlet, it is sprayed into the chamber from the fluid distribution port and flows out from the chamber to the steam outlet.

[0016] In this technical solution, water flows from the water inlet through the fluid distribution chamber. When the fluid distribution chamber is filled, water is sprayed into the chamber from the fluid distribution port, so that the pressure of the water entering the chamber is greatly enhanced. Among them, 6 to 12 fluid distribution ports are evenly arranged on the bottom side wall of the fluid distribution chamber. The multiple fluid distribution ports decompose a single stream of water into multiple streams of water, and spray the water horizontally into the chamber. Since the space in the chamber is small, the posture of the fluid suddenly changes from horizontal to vertical, and then passes through the chamber longitudinally, achieving the effect of spraying the fluid upward. At the same time, since the water flow is heated in the chamber and its volume expands, it is further subjected to pressure to ensure upward flow.

[0017] On the other hand, the fluid distribution chamber is actually a gravity back suction chamber, which can use the gravity of the water flow to discharge the dirt in the valve core and the chamber. Its main working principle is: in normal operation, the fluid distribution chamber is filled with water; when it is necessary to discharge sewage, the external water source cuts off the water supply to the fluid distribution chamber, and by placing the steam generator vertically, the water in the fluid distribution chamber is directly discharged under the action of gravity. While gravity discharges water, it also changes the pressure of the inner wall chamber of the outer core and the inner core, so that the pressure of the fluid distribution port and the chamber becomes smaller instantly, forming a pressure difference with the outside world, so that the outside world forms a relative back suction force. Under the action of the back suction force, the dirt adhering to the outer core, the inner core and the chamber is discharged to the bottom of the water inlet together with the water flow. And according to the principle of gravity acceleration, as time goes on, the greater the gravity acceleration, the greater the pressure difference formed, and the smaller the pressure in the chamber, so that the sewage mixture is discharged outside the valve core.

[0018] Furthermore, the interior of the chamber is divided into a fluid change processing chamber and a steam pressure processing chamber according to the changing state of water flow when passing through, wherein the water flow is quickly heated and evaporated in the fluid change processing chamber to generate primary steam; the steam pressure processing chamber is used to change the flow velocity of the steam when it flows through and further heat the steam, so that the steam generates pressure through the change in flow velocity, so that the outflowing steam is high-temperature pressurized steam.

[0019] Furthermore, the fluid change processing chamber includes a fluid mutation front chamber and a water state conversion chamber arranged in sequence along the water flow direction. Liquid water is heated in the fluid mutation front chamber and generates primary steam when entering the water state conversion chamber.

[0020] In the present technical solution, water is quickly heated when it enters the fluid mutation front chamber, and the heated water is converted into a steam-water mixture, causing the volume to continue to increase, thereby causing the steam-water mixture to continue to flow upward. The further it flows upward, the higher the heating temperature is, and when it enters the water state conversion chamber, primary steam is continuously generated.

[0021] Furthermore, a spring is provided in the fluid mutation front cavity, and the spring is arranged around the outer wall of the inner core. The cross-sectional diameter of the spring is smaller than the cross-sectional diameter inside the cavity, so that the spring can slide freely in the fluid mutation front cavity.

[0022] In this technical solution, the main function of the spring is to limit the flow and remove scale. In terms of flow limiting, the chamber with the spring will block the flow of part of the fluid compared to the chamber without the spring, thereby playing a role in limiting the flow. Since the pressure is high where the flow rate is low, the setting of the spring increases the pressure of the soda-water mixture, thereby causing the flow rate to flow upward quickly.

[0023] In terms of scale removal, since the spring has tensile force, when water vapor passes through the chamber, the spring is affected by the water vapor and gravity, and continuously moves up and down. During the movement, it continuously rubs and scrapes against the outer wall of the inner core and / or the inner wall of the outer core, thereby effectively removing scale in the chamber and ensuring the quality of water vapor.

[0024] Furthermore, the steam pressure processing chamber includes a pressure control and flow control chamber, a pressure holding chamber and a reverse fluid conversion chamber which are arranged in sequence along the water flow direction, wherein a spiral wire is provided in the pressure control and flow control chamber, and a reverse spiral structure is provided in the reverse fluid conversion chamber. When the primary steam flows through the pressure control and flow control chamber, it moves upward in a spiral shape due to the action of the spiral wire, thereby generating centrifugal force to separate gaseous water and liquid water; when entering the pressure holding chamber, the steam is buffered in the pressure holding chamber; when passing through the reverse fluid conversion chamber, the reverse spiral structure reduces the flow speed of the steam, so that the steam is further heated in the reverse fluid conversion chamber, and the steam flowing out is high-temperature pressurized steam.

[0025] In this technical solution, when the primary steam enters the pressure-control and flow-control cavity, it moves upward in a spiral shape through the action of the spiral wire and generates centrifugal force, which generates acceleration and speeds up the flow rate. In addition, due to the action of the centrifugal force, the liquid water is thrown to the inner wall of the outer core due to gravity during the upward process, so that the liquid water and the gaseous water are separated, and the liquid water that is not completely evaporated is further heated and evaporated into saturated steam on the inner wall of the outer core. At the same time, due to the flow control effect of the spiral line in the pressure-control and flow-control cavity, the pressure of the steam is increased. After the steam enters the pressure-maintaining cavity to be buffered and further heated, it enters the reverse fluid conversion cavity for further heating and pressurization, so that the outflowing steam is high-temperature pressurized steam.

[0026] Furthermore, the helical direction of the reverse helical structure is opposite to the helical direction of the helical filament.

[0027] Furthermore, the cross-sectional diameter of the fluid passing through the pressure control and flow control cavity is smaller than the cross-sectional diameter in the pressure holding cavity and larger than the cross-sectional diameter in the reverse fluid conversion cavity; the spiral line density in the pressure control and flow control cavity is smaller than the reverse spiral structure density in the reverse fluid conversion cavity.

[0028] In the present technical scheme, since a spiral line is provided in the pressure control and flow control chamber, and a reverse spiral structure is provided in the reverse fluid conversion chamber, the chamber space through which steam passes through the pressure control and flow control chamber and the reverse fluid conversion chamber is reduced, while the chamber space through which steam passes through the pressure maintaining chamber is relatively large, thereby slowing down the speed at which primary steam enters the pressure control and flow control chamber, but increasing the pressure, and increasing the speed at which the primary steam enters the pressure maintaining chamber from the pressure control and flow control chamber. However, since the chamber space in the reverse fluid conversion chamber is further reduced, the steam buffers and stays in the pressure maintaining chamber, continues to be heated, and then flows out through the reverse fluid conversion chamber. Since the outlet space of the reverse fluid conversion chamber is larger than the chamber space, high-temperature pressurized steam is formed.

[0029] Furthermore, a spiral groove is provided on the inner core, and the groove corresponds to the position of the pressure and flow control cavity in the chamber.

[0030] Furthermore, a buffer space for temporarily accommodating steam is reserved in the pressure-maintaining chamber, and the steam that is not completely vaporized is further heated and evaporated into saturated steam in the buffer space.

[0031] Furthermore, a pressure control terminal is provided on the top of the inner core, and the edge of the pressure control terminal protrudes from the space where the chamber is located, so that the space where the chamber is located is reduced, and the reduced chamber is connected to the steam outlet.

[0032] In this technical solution, the setting of the pressure control terminal is mainly to reduce the space when the steam flows out of the chamber, so as to reduce the cross-sectional area when the steam flows out of the chamber. According to Bernoulli's principle, the steam flows out quickly from the reduced chamber, the pressure at the reduced chamber position is small, and the pressure below the reduced chamber is large, so that the steam is ejected upward quickly.

[0033] Furthermore, the outer wall of the high-frequency alternating current generating coil is provided with a high-frequency magnetic field line shielding magnetic strip for shielding electromagnetic radiation.

[0034] Furthermore, the outer wall of the outer core is provided with a generator coil bracket for mounting a high-frequency alternating current generating coil.

[0035] Furthermore, a temperature control device is provided on the outer wall of the outer core and near the steam outlet.

[0036] Furthermore, the inner core can be made of high-temperature polytetrafluoroethylene, which has the characteristics of high temperature resistance and extremely low friction coefficient, and has wear resistance and lubricity, which can reduce the possibility of scaling and make the steam smoother.

[0037] Furthermore, the material of the inner core can also be made of magnetic material. The magnet can magnetize and soften water, reduce the formation of scale, improve the safety of drinking water and gas, and produce beneficial elements to the human body.

[0038] Compared with the prior art, the present invention has the following beneficial effects:

[0039] (1) The technical solution arranges the inner core inside the outer core, and the water flow passes through the chamber between the inner core and the outer core. The vortex principle is used to make the water flow continuously heated and evaporated into saturated water vapor during the process of passing through the chamber, which has the beneficial effects of fast heating efficiency, large steam output capacity and safety and reliability.

[0040] (2) The present technical solution utilizes the spiral lines in the pressure-controlling and flow-controlling chamber, the buffering effect of the pressure-maintaining chamber, and the reverse spiral structure in the reverse fluid conversion chamber to further heat and pressurize the steam-water mixture passing through the chamber. Since the spiral lines and the reverse spiral structure change the circulation area of ​​the steam-water mixture in the chamber, the saturation of the outflowing water vapor is guaranteed with a certain pressure, which can better meet people's needs.

[0043] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0044] Example 1

[0045] like Figure 1 and Figure 2 As shown, a high-frequency electromagnetic plunger steam generator includes a main valve core, a water inlet 1 is provided at the bottom of the main valve core, and a steam outlet 2 is provided at the top; wherein, the main valve core includes an outer core 3 and an inner core 4, the outer core 3 is a hollow structure, the inner core 4 is arranged in the hollow structure of the outer core 3, and a chamber 5 for water flow is reserved between the outer core 3 and the inner core 4; a high-frequency sudden current generating coil 6 is provided on the outer wall of the outer core 3, and the high-frequency sudden current generating coil 6 is electrically connected to the external steam generator mainboard, and generates an alternating electric field to act on the outer core, and according to the eddy current principle, the main valve core heats up rapidly, so that the temperature in the chamber increases, and water flows in from the water inlet 1, evaporates into water vapor when passing through the chamber 5, and then flows out from the steam outlet 2.

[0046] This technical solution mainly utilizes the principle of eddy current, with the outer core 3 as a conductor. The external steam generator mainboard is connected to the high-frequency alternating current generating coil 6 and resonates with the outer core, thereby generating an alternating electric field acting on the outer core 3, so that the main valve core itself heats up rapidly, and the fluid flows through the chamber 5 between the outer core 3 and the inner core 4, thereby achieving the purpose of heating the fluid.

[0047] Since the eddy current phenomenon generates a lot of heat, the water entering the chamber 5 can quickly heat up and quickly generate saturated steam. At the same time, high-frequency electromagnetic heating is used to make the inner core 4 and the outer core 3 self-heated instead of heat transfer, and the self-heating temperature rises quickly, thereby effectively improving the steam saturation.

[0048] In this embodiment, a hollow fluid distribution chamber 41 is provided in the lower half of the inner core 4, and a fluid distribution port 42 is provided on the bottom side wall of the fluid distribution chamber 41; the fluid distribution port 42 is connected to the chamber 5, and the fluid distribution chamber 41 is connected to the water inlet 1. After the external water enters the fluid distribution chamber 41 from the water inlet 1, it is sprayed into the chamber 5 from the fluid distribution port 42 and flows out from the chamber 5 to the steam outlet 2.

[0049] In the present technical solution, water flows from the water inlet 1 through the fluid distribution chamber 41. When the fluid distribution chamber 41 is filled, water is sprayed from the fluid distribution port 42 to the chamber 5, so that the pressure of the water entering the chamber 5 is greatly enhanced. Among them, 6 to 12 fluid distribution ports 42 are evenly arranged on the bottom side wall of the fluid distribution chamber 41. The multiple fluid distribution ports 42 decompose a single stream of water into multiple streams of water, and make the water flow horizontally close to the chamber 5. Since the space of the chamber 5 is small, the posture of the fluid suddenly changes from horizontal to vertical, and then passes through the chamber 5 vertically, achieving the effect of spraying the fluid upward. At the same time, since the water flow is heated in the chamber 5 and the volume expands, it is further subjected to pressure to ensure upward flow.

[0050] On the other hand, the fluid distribution chamber 41 is actually a gravity back suction chamber, which can use the gravity of the water flow to discharge the dirt in the valve core and the chamber. Its main working principle is: in normal operation, the fluid distribution chamber is filled with water; when it is necessary to discharge sewage, the external water source cuts off the water supply to the fluid distribution chamber, and by placing the steam generator vertically, the water in the fluid distribution chamber is directly discharged under the action of gravity. While gravity discharges water, it also changes the pressure of the inner wall chamber of the outer core and the inner core, so that the pressure of the fluid distribution port and the chamber becomes smaller instantly, forming a pressure difference with the outside world, so that the outside world forms a relative back suction force. Under the action of the back suction force, the dirt adhered to the outer core, the inner core and the chamber is discharged to the bottom of the water inlet together with the water flow. And according to the principle of gravity acceleration, as time goes on, the greater the gravity acceleration, the greater the pressure difference formed, and the smaller the pressure in the chamber, so that the sewage mixture is discharged outside the valve core.

[0051] In this embodiment, the interior of the chamber 5 is divided into a fluid change processing chamber 51 and a steam pressure processing chamber 52 according to the changing state of water flow when passing through, wherein the water flow is quickly heated and evaporated in the fluid change processing chamber 51 to generate primary steam; the steam pressure processing chamber 52 is used to change the flow velocity of the steam when it flows through and further heat the steam, so that the steam generates pressure through the change in flow velocity, so that the outflowing steam is high-temperature pressurized steam.

[0052] In this embodiment, the fluid change processing chamber 51 includes a fluid mutation front chamber 511 and a water state conversion chamber 512 arranged in sequence along the water flow direction. The liquid water is heated in the fluid mutation front chamber 511 and generates primary steam when entering the water state conversion chamber 512.

[0053] In the present technical solution, the water flow is quickly heated when entering the fluid mutation front chamber 511, and the heated water flow is converted into a steam-water mixture, causing the volume to continue to increase, thereby causing the steam-water mixture to continue to flow upward. The further it flows upward, the higher the heating temperature is, and when entering the water state conversion chamber 512, primary steam is continuously generated.

[0054] In this embodiment, a spring 53 is provided in the fluid mutation front chamber 511 , and the spring 53 is arranged around the outer wall of the inner core 4 . The cross-sectional diameter of the spring 53 is smaller than the cross-sectional diameter in the chamber 5 , so that the spring 53 can slide freely in the fluid mutation front chamber 511 .

[0055] In the present technical solution, the function of the spring 53 is mainly to limit the flow and remove scale. In terms of flow limiting, the chamber provided with the spring 53 will block the flow of part of the fluid relative to the chamber without the spring 53, thereby playing a role in limiting the flow. Since the pressure is high where the flow rate is low, the setting of the spring 53 increases the pressure of the soda-water mixture, thereby causing the flow rate to flow upward quickly.

[0056] In terms of scale removal, since the spring 53 has a tensile force, when the water vapor passes through the chamber 5, the spring is affected by the water vapor and gravity, and continuously performs up and down telescopic movements. During the movement, it continuously rubs and scrapes against the outer wall of the inner core and / or the inner wall of the outer core, thereby effectively removing the scale in the chamber 5 and ensuring the quality of the water vapor.

[0057] In this embodiment, the steam pressure processing chamber 52 includes a pressure control and flow control chamber 521, a pressure holding chamber 522 and a reverse fluid conversion chamber 523 which are arranged in sequence along the water flow direction, wherein a spiral wire 54 is provided in the pressure control and flow control chamber 521, and a reverse spiral structure 55 is provided in the reverse fluid conversion chamber 523. When the primary steam flows through the pressure control and flow control chamber 521, it moves upward in a spiral shape due to the action of the spiral wire 54, thereby generating centrifugal force to separate gaseous water and liquid water; when entering the pressure holding chamber 522, the steam is buffered in the pressure holding chamber, thereby continuing to heat up and evaporate into saturated steam; when passing through the reverse fluid conversion chamber 523, the reverse spiral structure 55 reduces the flow speed of the steam, so that the steam is further heated in the reverse fluid conversion chamber 523, so that the outflowing steam is high-temperature pressurized steam.

[0058] In the present technical solution, when the primary steam enters the pressure control and flow control cavity 521, it moves upward in a spiral shape due to the action of the spiral wire 54 and generates centrifugal force, which generates acceleration and speeds up the flow rate. In addition, due to the action of the centrifugal force, the liquid water is thrown to the inner wall of the outer core 3 due to gravity during the rising process, so that the liquid water and the gaseous water are separated, and the liquid water that has not been completely evaporated is further heated and evaporated into saturated steam on the inner wall of the outer core. At the same time, due to the flow control effect of the spiral line 54 in the pressure control and flow control cavity 521, the pressure of the steam is increased.

[0059] In this embodiment, the spiral direction of the reverse spiral structure 55 is opposite to the spiral direction of the spiral wire 54 .

[0060] In this embodiment, the cross-sectional diameter of the fluid passing through the pressure control and flow control cavity 521 is smaller than the cross-sectional diameter inside the pressure maintaining cavity 522 and larger than the cross-sectional diameter of the reverse fluid conversion cavity 523; the density of the spiral line 54 inside the pressure control and flow control cavity 521 is smaller than the density of the reverse spiral structure 55 inside the reverse fluid conversion cavity 523.

[0061] In this embodiment, a spiral groove is provided on the inner core 4 , and the groove corresponds to the position of the pressure and flow control cavity 521 in the chamber, and the spiral line 54 is fixed in the groove.

[0062] In this embodiment, a buffer space for temporarily accommodating steam is reserved in the pressure-maintaining chamber 522 , and the steam that is not completely vaporized is further heated and evaporated into saturated steam in the buffer space.

[0063] In this embodiment, a pressure control terminal 7 is provided on the top of the inner core 4, and the edge of the pressure control terminal 7 protrudes from the space where the chamber 5 is located, so that the space where the chamber 5 is located is reduced, and the reduced chamber 5 is connected to the steam outlet.

[0064] In the present technical solution, the setting of the pressure control terminal 7 is mainly to reduce the space when the steam flows out of the chamber 5, so as to reduce the cross-sectional area when the steam flows out of the chamber 5. According to the Bernoulli principle, the steam flows out quickly from the reduced chamber 5, the pressure at the reduced chamber 5 is small, and the pressure below the reduced chamber 5 is large, so that the steam is ejected upward quickly.

[0065] In this embodiment, the outer wall of the high-frequency alternating current generating coil 6 is provided with a high-frequency magnetic field line shielding magnetic strip 8 for shielding electromagnetic radiation.

[0066] In this embodiment, the outer wall of the outer core 3 is provided with a generator coil bracket 9 for mounting the high-frequency alternating current generating coil 6 .

[0067] In this embodiment, a temperature control device 10 is provided on the outer wall of the outer core 3 and near the steam outlet.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the technical solution of the present invention, and are not intended to limit the specific implementation methods of the present invention.
