The present invention relates generally to an apparatus for supplying hot water and, more particularly, to a hot water supply apparatus using a revolving magnetic body, the apparatus being driven with low power consumption while being environment-friendly and having excellent safety.
In general, a boiler used as an apparatus for supplying hot water is installed in homes, buildings, and various facilities to supply hot water or heating in the seasons, and includes various kinds of boilers such as a small boiler used in homes, and a large boiler used in various facilities.
Such a boiler usually supplies hot water or heating to users by burning fuel energy such as gas, petroleum, light oil or the like to heat water. Herein, a heat exchange body of the boiler directly burns fuel such as gas or petroleum, heats water by using heat energy generated during burning, and discharges exhaust gas generated during burning to the outside through an externally installed chimney.
The above-described apparatus for supplying hot water is problematic in that exhaust gas is generated due to the use of fuel, and it may lead to an explosion accident, thereby posing a problem in safety.

Accordingly, the present invention has been made keeping in mind the above problems occurring in the related art, and an object of the present invention is to provide a hot water supply apparatus using a revolving magnetic body, the apparatus being driven with low power consumption while being environment-friendly and having excellent safety when hot water and heating are supplied.
In order to accomplish the above object, the present invention provides a hot water supply apparatus using a revolving magnetic body, the apparatus including: a heat exchange body containing water, and including a circular heating pipe circumferentially provided in the heat exchange body; a stator wound with a plurality of coils to encompass an outside of the heat exchange body, and magnetized when an electric current is applied thereto, wherein the heating pipe includes therein a magnetic body that revolves along the circumference of the heating pipe due to a magnetic field formed by the stator, so that water is heated by frictional heat generated when the magnetic body revolves.
As described above, according to the present invention, water is heated using the frictional heat generated when the magnetic body revolves along the circumference of the heating pipe due to the magnetic field formed by the magnetized stator rather than using any fuel, so it is possible to realize safety and an environment-friendly effect when hot water and heating are supplied.

The present invention relates to an apparatus for supplying hot water and, more particularly, to a hot water supply apparatus using a revolving magnetic body, wherein the apparatus is driven with low power consumption while being environment-friendly and having excellent safety when hot water and heating are supplied, the apparatus including: a heat exchange body containing water and including a circular heating pipe circumferentially provided in the heat exchange body; and a stator wound with a plurality of coils to encompass an outside of the heat exchange body, and magnetized when an electric current is applied thereto, wherein the heating pipe includes therein a magnetic body that revolves along the circumference of the heating pipe due to a magnetic field formed by the stator, whereby water is heated by frictional heat generated when the magnetic revolves.
Before the present invention is described in detail, it should be noted that the scope of the present invention is not limited to the embodiments described below, and those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention.
Hereinafter, the apparatus for supplying hot water using the revolving magnetic body of the present invention will be described in detail with reference to
As shown in
More specifically, the heat exchange body 100 and the heating pipe 200 may have various shapes. However, as shown in the drawing, the heat exchange body 100 may have a cylindrical shape, and the heating pipe 200 may have a circular shape and may be circumferentially provided in the heat exchange body 100 such that the magnetic body 10 provided in the heating pipe 200 revolves along the circumference thereof. Further, the heat exchange body 100 and the heating pipe 200 may be made of a material such as copper, aluminum, etc. having diamagnetic properties, so as to be prevented from influence from a magnetic field. Hereinafter, this will be described on the basis of this premise.
The stator 300 is wound with the plurality of coils, and is magnetized and forms a magnetic field when a current is applied thereto. The stator 300 may be provided on an inner surface of a housing A including therein the heat exchange body 100 and the stator 300. Specifically, as shown in
The magnetic body 10 may have ferromagnetic properties and thus revolves along the circumference of the heating pipe 200 due to the magnetic field formed by the stator 300. The heating pipe 200 is heated by frictional heat generated when the magnetic body 10 revolves and thus friction occurs, and water that is in contact with or contained in the vicinity of the heating pipe 200 is heated by the frictional heat. Accordingly, the heating pipe 200 may be made of a material having a high thermal conductivity. Meanwhile, the water may be contained in the heating pipe 200 without flowing in and out, and as shown in
As described above, since the present invention uses the frictional heat generated by the magnetic body 10 revolving, it is possible to heat water without using any fuel, thereby being environment-friendly, and to ensure safety in supplying heated water, that is, hot water to users and in supplying heating using hot water. In addition, since it is the magnetic body 10 provided in the heating pipe 200 to be actually affected by the magnetic field, it is possible to realize driving with low power consumption.
Meanwhile, the heating pipe 200 may include therein a viscous fluid having viscosity such as oil such that the magnetic body 10 can efficiently revolve along the circumference of the heating pipe 200. The viscous fluid may include solid particles such as iron oxides such that the solid particles are caused to collide with friction particles during revolving of the magnetic body 10, thereby increasing frictional heat.
The viscous fluid may use a material that is easy to use for lubrication and heat transfer. For example, a heating medium oil, which is a synthetic oil used for heat transfer such as heating, heat removal, etc., may be used.
The magnetic body 10 may be entirely made of a material having ferromagnetic properties, and as shown in
Meanwhile, as shown in
Further, as shown
Moreover, as shown in
Meanwhile, although not shown in the drawing, a plurality of heat exchange bodies 100 may be provided inside the stator 300. Herein, a first one of the heat exchange bodies 100 may have a different radius from a second one of the heat exchange bodies 100 such that the second heat exchange body 100 is placed inside the first exchanger 100. Since the magnetic body 10 must revolve along the outer circumference of the heating pipe 200, each of the plurality of heat exchange bodies 100 may be provided within the range of the magnetic field formed by the stator 300.
Further, as shown in
Further, the present invention may include a rotor 400 including a plurality of permanent magnets, and the rotor 400 is rotated by a shaft 500 provided to pass through the heat exchange body 100 in the lengthwise direction thereof. Herein, the heat exchange body 100 and the rotor 400 are placed inside the stator 300.
Specifically, as shown in
For example, the load 600 may be a pump, and the pump may be provided at the side or the opposite sides of the shaft 500. Such a pump may serve to supply water to the inside of the heat exchange body 100, that is, to the heating flow passage 20, by using the rotational force of the rotor 400.
Meanwhile, a usual frequency of an alternating current applied to the stator 300 is 50 Hz or 60 Hz. However, the present invention may further include a regulator for regulating the frequency of the electric current applied to the stator 300, such that a higher or lower frequency than the usual frequency is applied and thus the amount of frictional heat attributable to revolving of the magnetic body 10 is adjusted. In addition, the present invention may further include a temperature sensor capable of directly or indirectly measuring the temperature of water such that the temperature sensor turns ON/OFF the electric current to be applied to the stator 300 in response to a set temperature.
