_[0029][0029]

_[0030] Referring to FIG. 1, an embodiment of the present application provides a non-inductive water heater, including a housing 10 and a non-inductive coil 20.

_{[0031] The} housing 10 is provided with a water inlet 1^ and a water outlet 1 3⁄4. The water inlet 1 ^ is used for water supply inflow, the water outlet 1 3⁄4 is used for water supply and outflow, generally the ground, the water inlet 1 can be connected to the tap water through the pipe, the water outlet 1 \¥0 2019/095356 卩(:17€\2017/111824

(3⁄4 can be connected to the shower.

[0032] The non-inductive coil 20 is disposed in the casing 10, and the non-inductive coil 20 is used for heat generation to heat the water flowing into the water inlet 11 of the casing 10. In an embodiment, the non-inductive coil 20 can be made by folding a length of a wire into a circular shape from the folded portion, so that one end of the circular arc is a fold of the non-inductive coil 20, and the other end is The head and the tail of the non-inductive coil 12, wherein the electric wire comprises a conductor wire and an insulating layer wrapped around the conductor wire. Referring to FIG 2, two strands of wire close together and between 20 & ₂₀₁₅ are separated by an insulating layer on the non-inductive coil 20 off.

[0033] In an embodiment, the non-inductive coil 20 may be spirally disposed as a whole in a long rod shape.

[0034] It should be noted that the structure of the non-inductive water heater of FIG. 1 is for illustrative purposes only and is not intended to be limiting. For example, the water inlet 1 〇 & the water outlet _{10 5 of the} non-inductive water heater may also be disposed in other parts of the housing.

_[0035] As shown in _{FIG. 3,} in one embodiment, the water heater without a sense of storage water heaters, which further comprises a liner _11, the liner _{11 is} provided inside the housing ₁₀ and communicates water inlet and a water outlet _{10 &} _{1 (¾,} in an embodiment for storing the water inlet ₁₀ and water flowing _& supply outlet _{1 (¾.} no induction coil ₂₀ is provided in the interior of the liner ₁₁ to heat water stored in the tank ₁₁ from in no sense coils ₂₀ disposed in the axial direction of the liner ₁₁ in the interior of the liner _11. it should be said that some, FIG. ₃ is a front perspective view of a non-inductive heater cutaway portion, which can easily show the inside thereof The inner casing ₁₁ and the non-inductive coil _20. In an embodiment, the inner casing ₁₁ and the casing ₁₀ may also be filled with an insulating material.

[0036] as shown in Figure 4 ( _&) and

As shown, in one embodiment, the non-inductive water heater is an instant water heater, which further includes a water pipe 12 disposed inside the casing 10 and communicating with the water inlet 10 & and the water outlet 1 (3⁄4, for water supply from The water inlet 1〇3 flows in and flows out from the water outlet 1 (3⁄4. The non-inductive coil 20 is disposed inside the water pipe 12, when water flows in from the water inlet 10&&&&&&&&&&&&&&&&&&&&&&&&& During the process, the water is heated. In one embodiment, the non-inductive coil 20 is helically disposed and integrally arranged to match the shape of the water tube 12. wherein Figure 4 ( _&) is to cut the front side of the non-inductive water heater and the water tube 12 A part thereof makes it possible to conveniently display the water pipe 12 and the non-inductive coil 20 inside thereof.

[0037] The above is a structural description of the non-inductive water heater in some embodiments.

[0038] Since the non-inductive coil 20 has substantially no reactance, so that the reactive power consumption is very low, its power can be made high.

In addition, the current in the non-inductive coil 20 is equal everywhere, the heat distribution is uniform, and the place where the current is large is not aging due to the current inconsistency. \¥0 2019/095356 卩(:17€\2017/111824

_{[0039] The} induction coil ₂₀ so that no work has a variety of ways, the following will be described by several embodiments.

[0040]

_[0041] Example ₁

_[0042] In the present embodiment, as shown in FIG. 5, no sense coils ₂₀ are formed end to end path for sensing a changing magnetic field to produce a heating current.

[0043] In an embodiment, the non-inductive water heater may further include a component 31 for providing a non-inductive coil 20 with a varying magnetic field after energization. The component 31 can be made using the present principles, such as the principle of an induction cooker, or it can be made using a future appearance principle as long as a varying magnetic field is provided.

[0044] Since the magnetic field for sensing the change is the non-inductive coil 20, which is a series structure, the current generated by the non-inductive coil due to the induced magnetic field is equal everywhere, unlike the conductor commonly used for inductively changing magnetic fields. Similarly, eddy currents are generated throughout the conductor, resulting in uneven temperature and accelerated aging.

_[0045] Further, since no induction coil ₂₀ is coupled to member _31, member ₃₁ is directly connected to the external power source (e.g., electricity), and therefore greatly improves the safety of electricity.

_[0046][0046]

Example 2

_[0048] In the present embodiment, shown in Figure _6, further comprising a heater without a sense of high frequency AC power supply _32, a high-frequency output ends of the AC power supply ₃₂ are connected to the free end to the sensing coil _20, a high-frequency AC power source ₃₂ It is used to connect the external power supply (for example, mains) and turn the connected power supply into a high-frequency low-voltage AC output to the non-inductive coil. _{20 The} non-inductive coil ₂₀ can be heated and then heated. In one embodiment, the high frequency AC power source ₃₂ includes a rectifier circuit (not shown) for converting the voltage of the external power source to a voltage of _8000-2000000 Hz and a voltage of _36-80 volts.

_[0049] Since the non-inductive coil ₂₀ receives a high-frequency power, it will produce the skin effect (skin effect), so that heat is concentrated at the surface of the non-inductive coil, the heat transfer distance is significantly reduced, the efficiency is very high. In addition, when the temperature is increased, the resistance of the non-inductive coil ₂₀ becomes large, but since the voltage output from the high-frequency AC power source ₃₂ to the non-inductive coil ₂₀ is constant, the current in the non-inductive coil ₂₀ is reduced, and the current is reduced. The temperature is lowered to form a feedback that maintains a constant temperature. Further, since the high-frequency AC power supply _{32 is} output to the non-inductive coil ₂₀ as a low-voltage power, it is relatively safe.

_[0050] \¥0 2019/095356 卩(:17€\2017/111824

_[0051] Example ₃

_[0052] In the present embodiment, as shown in _{FIG. 7,} the water heater further comprises a non-inductive energy storage unit _33, the storage unit ₃₃ outputs positive and negative terminals are respectively connected to the free end to the sensing coil _20, the storage unit ₃₃ is connected After the external power supply (for example, commercial power) is charged, after the external power supply is disconnected, the low-voltage direct current can be supplied to the non-inductive coil ₂₀ , and the non-inductive coil ₂₀ is heated after being energized.

_[0053] Since the energy storage unit ₃₃ actually disconnects from the external power source during use and supplies low voltage direct current to the non-inductive coil ₂₀ , it is safer.

_[0054][0054]

_[0055] Application of the above specific examples of the present invention is illustrated, merely for understanding the present invention is not intended to limit the present invention. Variations to the above-described embodiments may be made by those skilled in the art in light of the concept of the invention.
