The lightning resistance uses a current to cause the conductor to generate heat, and the conductor of the low electric P is put into the heating officer to heat the water stream by resistance heating. Although the electric water heater system is the right pair of resistance heating, it can avoid the problem of redox or the money burning by the king - oxidation & poisoning, but because the electric water heater plus the teaching tube inside the tube and the tube wall only use thin The thin insulation sheet is isolated, so it is easy to cause the risk of electric leakage. And if the electric water heater is empty, the overheated heating tube is also in danger of exploding. Because the electromagnetic induction magnetic field coil is not in direct contact with the water flow, and does not need to be burned, Therefore, the electromagnetic induction heating water heater can simultaneously have the hot water protection against the danger of carbon monoxide poisoning and electric leakage. However, the existing electromagnetic induction water heaters on the market mostly place the magnetic conductive water pipes in the coils, so that the water storage devices of the water heaters are limited by the coils, and the effective method is long: the water heater performance of the electromagnetic induction heating. This creation is aimed at the structure of the electromagnetic induction water heater, which uses the technology of the planar coil disk to increase the electromagnetic induction ^ M311000 ^ water heater application, and break through the limitations of the water storage equipment, and further improve the efficiency of the water heater. [New content] The purpose of this creation is to provide an electromagnetic induction water heater that uses a flat coil disk to generate a high-frequency magnetic field, and a magnetic metal tank that senses magnetic energy to generate heat energy to heat the water flow. In order to achieve the above object, the present invention provides an electromagnetic induction water heater, comprising a magnetic metal water tank and a planar coil, wherein the planar coil is disposed adjacent to a side surface of the metal water tank, and when the planar coil is circulated An induced magnetic field is generated when the high frequency current is generated, and the metal water tank reacts with the change of the induced magnetic field to generate thermal energy. The electromagnetic induction water heater of the present invention achieves the above purpose, because the planar coil disk is in contact with the metal water tank through the ceramic plate, the ultra-high insulation degree can completely avoid the danger of leakage of the planar coil disk and the metal water tank, and the heat energy due to high frequency electromagnetic induction The conversion efficiency is much higher than that of the conventional electric water heater, so it is very suitable for the application of the water heater, and the number of the flat wire and the number of the coils can be increased or decreased depending on the situation to be applied to the hot water heater or the storage water heater with a larger water output. The above-mentioned objects or features of the present invention will be described in detail in accordance with the following drawings. However, it should be understood that the following drawings and examples are merely illustrative and not limiting or limiting the present invention. [Embodiment] This creation is an electromagnetic induction that uses the south frequency electromagnetic induction to generate thermal energy. 6 M311000 The water heater generates heat by a non-contact conductor to induce a change in the magnetic field to heat the inside of the water tank. Referring to the first drawing, a structural sectional view of an electromagnetic induction water heater according to a preferred embodiment of the present invention includes a composite array of planar coil disks 11, 12, and a metal water tank 20. The metal water tank 20 has a water inlet 21 and a water outlet 22. When the water flows into the metal water tank 20 through the water inlet 21, the planar coil disks 11, 12 can heat the water flow through the metal water tank 20 and heat the water. The subsequent water flow flows out of the metal water tank 20 through the water outlet 22. The metal water tank 20 is further provided with a metal heat conduction plate 23 which is arranged in a staggered arrangement, and the metal water tank 20 and the metal heat conduction plates 23 are made of a metal having magnetic properties. Since the planar coil disks 11, 12 generate a high-frequency current, the planar coil disks 11, 12 generate an induced magnetic field, so that the metal water tank 20 and the metal heat conducting plates 23 can sense changes in the surrounding magnetic field. Eddy Current is generated, resulting in a large amount of thermal energy. The metal heat conducting plates 23 can change the direction of the water flowing inside the metal water tank 20 in a staggered configuration, in addition to the heat energy generated by the field change, to define the water flow path distance from the water inlet 21 to the water outlet 22, and The speed of the water flow can be slowed to increase the residence time of the water flowing inside the metal water tank 20 to achieve a better heating effect. Since the induced magnetic fields generated by the planar coil disks 11, 12 are not a uniform magnetic field, the induced magnetic field induced at a partial position on the side surface of the metal water tank 20 close to the planar coil disks 11, 12 is strongest. Therefore, by disposing the metal heat conducting plate 23 at the above positions, the heat energy generated by the metal water tank 20 and the metal heat conducting plates 23 in response to the induced magnetic field can be maximized to 7 M311000. Since the metal water tank 20 generates heat by reacting a change in the magnetic field of the induced magnetic field generated by the planar coil disks 11, 12, the safety considerations in use are considered, and in order to prevent the metal water tank 20 from being burnt, the metal water tank 20 is tied out. The water port 22 is provided with a water pressure detector 31 (refer to the second figure) for detecting whether the metal water tank 20 is full of water. When the water pressure detector 31 detects a full water condition, the planar coil disks 11, 12 can be turned on and generate an induced magnetic field. Further, the metal water tank 20 is provided with a water temperature detector 32 at an appropriate position for detecting the temperature of the heated water inside the metal water tank 20 to obtain temperature information required for temperature control or constant temperature control. Referring to the second drawing, the front view of the electromagnetic induction water heater of the preferred embodiment shown in the first embodiment includes planar coil disks 11, 12. Taking the planar coil disk 11 as an example, the planar coil disk 11 is a planar spiral coil disk which is tightly wound into a coil disk in a spiral manner. When the planar coil disk 11 is subjected to a high frequency current, the plane coil disk 11 generates an inductive magnetic field according to Ampere's Law and Faraday's Lenz Law. Since the metal water tank 20 and the multi-array heat conducting plate 23 are all magnetically conductive metals, the metal water tank 20 and the heat conducting plates 23 generate eddy currents in the induced magnetic field, and the eddy current is the metal. The surface of the water tank 20 and the heat conducting plates 23 generates a skin effect, so that the surface of the metal water tank 20 and the heat conducting plates 23 generates heat energy and flows through the surface of the metal water tank 20 and the heat conducting plates 23. The water stream is heated. When the high-frequency current that the planar coil disk 11 is turned on is higher, the generated induced magnetic field is stronger, so that the heat energy generated by the metal water tank 20 and the heat conducting plates 23 is increased. 8 M311000 Refer to the third figure for a schematic diagram of the control concept of the planar coil disk u. The electromagnetic induction hot water is connected to the planar coil disk u and the metal water raft 20 by a control device 4, and the control device 4 receives the water, the signal and the water detected by the water pressure detector 31. The water temperature signal detected by the temperature detector 32 uses the water pressure signal and the water temperature signal to adjust the current applied to the planar coil disk 11. Referring to the fourth figure, a circuit diagram of the control device 4A is shown. The control device 4 includes a rectifier 41, an IGBT transistor 42, a pWM controller 43, and a CPU 44. The rectifier 41 is configured to convert an AC power source of a voltage of 110 volts or 220 volts supplied from the commercial power source 45 into a full-wave pulsating DC power source to provide an induced magnetic field to the planar coil disk. The IGBT transistor 42 is an Insulated_Gate Bipolar Transistor (IGBT). The output portion of the IGBT transistor 42 is a bipolar element, which can be used in a working field of up to 1000 volts or less, and the power loss is relatively low. Suitable for applications that use AC mains drives (such as drive motors, etc.), they are very efficient in high voltage and high power applications. The control device 40 shown in the fourth figure controls the opening and closing of the current flowing through the planar coil disks 11, 12 by the IGBT transistor 42. The Pwm controller 43 is a pulse width modulation controller (Pulse Width M〇dulat〇r), which is used for controlling the analog circuit by a digital signal, and the PWM controller 43 receives the digital output signal of the CPU 44 and controls The switching operation of the IGBT transistor 42. The CPU 44 is configured to receive the signal of the water pressure detector 31 and the water temperature detector 32, and push the PWM controller 43 to control the high frequency bandwidth of the switching of the igb^ transistor 42 to change the flow rate. The width of the high frequency switching current of the planar coil disk 11 is narrow, thereby controlling the magnitude of the induced magnetic field generated by the planar coil disk 9 M311000 11. The metal water tank 20 can be regarded as a short-circuit coil on the secondary side of a transformer in the circuit diagram shown in FIG. 4, and the metal water tank 20 and its metal heat conduction plate 23 are the same when the primary side coil coil 11 is turned on. The induction magnetic field generated by the planar coil disk 11 on the primary side is induced by electromagnetic induction, and a current is generated. Since the metal water tank 20 and the metal heat conduction plate 23 are short-circuited, extremely large heat energy is generated, and the electromagnetic induction of the present invention is generated. The disadvantage of the water heater is that the secondary side short-circuit heat in the transformer is converted into an advantage, and the metal water tank 20 generates heat energy according to the heat generation phenomenon and heats the water flowing therethrough. The electromagnetic induction water heater of the present invention can increase or decrease the number of planar coil disks according to the size of the water flow required for heating. When the number of planar coil disks is larger, the larger the induced magnetic field generated, the metal water tank 20 can be produced more. Big heat. According to experiments, the power of the planar coil disks 11 and 12 is 1300 watts to achieve the effect of the electromagnetic induction water heater with good performance, and the safety of the operation is considered. The preferred embodiment of the present invention is a single control device. Controlling a single planar coil disk simplifies the complexity of operation and protects the safety of the electromagnetic induction water heater and avoids expensive IGBT transistor damage. Referring to Fig. 5, there is shown a schematic diagram of a combination of two sets of control devices 51, 52. The control devices 51, 52 control the planar coil disks 11, 12 disposed on the two sides of the metal water tank 20, respectively. The control devices 51, 52 respectively include heat sinks 511, 521 to protect the control devices 51, 52 from damage due to overheating. The control devices 5 52 further include alarms 512, 522 such that sound effects are issued to alert the user when the control devices 51, 52 exceed the safe operating range. The control devices 51 and 52 receive the water pressure signal detected by the water pressure detector 31 inside the metal water tank 20 and the water temperature detector 32 through the ports 514 and 524 via the CPUs 513 and M311000. Detecting the water and temperature signals, and adjusting the currents applied to the planar coil disks 11, 12 by using the water pressure signals and the water temperature signals. Reference is made to the sixth diagram for a schematic diagram of the combination of the control devices 51, 52. When two sets of control devices 51, 52 are used, the control devices 51, 52 can be regarded as two coils connected in parallel on the primary side of the transformer, and at the same time, electromagnetic induction is applied to the metal water tank 20 on the secondary side. • The control devices 51 and 52 can control the current of the planar coil disks 11 and 12 by the water temperature signal detected by the water temperature detector 32 to control the temperature of the water flow, and can also set a certain temperature protection range. When the water temperature exceeds the temperature protection range, the currents of the planar coil disks 11 and 12 are cut off, or the planar coil disks 11 and 12 may be restricted according to the water pressure signals detected by the water pressure detector 31. The current is turned on or off to avoid damage to the electromagnetic induction water heater. Referring to Fig. 7, a cross-sectional view showing the structure of an electromagnetic induction water heater according to another preferred embodiment of the present invention. When the metal water tank 20 is a cylindrical tank, a spiral metal heat pipe 233 may be further disposed inside the metal water tank 20. The spiral metal heat pipe 233 is also made of a magnetically conductive metal, and the spiral metal heat pipe 233 is disposed on the inner peripheral wall of the metal water tank 20, and the spiral metal heat pipe 233 is provided. A channel can be formed inside the gold water tank 20 and define a water flow path distance from the water inlet 21 to the water outlet 22. The metal water tank 20 generates high temperature during operation, so that the planar coil disks 11, 12 and the metal water tank 20 are insulated by an insulating spacer 33 which is resistant to high temperature and does not conduct magnetic 11 M311000, and avoids such planes. The coil disks 11, 12 are damaged by the high temperature generated by the metal water tank 20. The metal water tank 20 can be a metal water pipe, which can be used to sense the change of the surrounding magnetic field and generate heat energy, and can also heat the water flowing through the water pipe. Since the planar coil disks 11, 12 are not in direct contact with the metal water tank 20, the risk of leakage of the metal water tank 20 can be completely avoided, and the heat energy conversion efficiency of the electromagnetic induction is much higher than that of the conventional electric water heater, so it is very suitable. It is used in water heater applications and can increase or decrease the number of flat coils/discs for use in instant water heaters or storage water heaters. Further, the planar coil disk in the preferred embodiment of the present invention can be combined with a device for heating a liquid such as a hot water bottle, thereby achieving a highly efficient and highly safe liquid heating effect. Having described the preferred embodiments of the present invention, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the scope and spirit of the inventions described herein. Embodiments of the embodiments are given.
