Referring to FIG. 1, the electric boiler 1 may include a case 3, a controller 4, inlet pipes 111 and 131, and discharge pipes 113 and 133.

The electric boiler 1 may include a carbon rod 710 (see FIG. 4) therein. A case 3 that may be a rectangular parallelepiped may be installed, and in this case, the electric boiler 1 may be located outside or inside the residence.

The fluid inlet pipes 111 and 131 and the discharge pipes 113 and 133 are connected to the bottom of the case 3 so that different fluids may be injected or discharged.

The fluid flowing into the case 3 through the inlet pipes 111 and 131 can be discharged through the discharge pipes 113 and 133 in a heated state, and the discharged fluids 5 and 6 are injected into the residence 2 and the residence ( The fluids 5 and 6 discharged from 2) may flow into the electric boiler 1.

That is, the fluids 5 and 6 may be used as heating or hot water by circulating the electric boiler 1 and the residence 2 through the inlet pipes 111 and 131 and the discharge pipes 113 and 133.

For example, the first fluid 5 flowing through the first inlet pipe 111 and the first discharge pipe 113 may be water.

At this time, water is introduced into the electric boiler 1 through the first inlet pipe 111 and heated, and then discharged through the first discharge pipe 113 to be used as hot water in the residence 2.

In addition, the used hot water may again flow into the electric boiler 1 through the first inlet pipe 111. That is, water may be circulated through the first inlet pipe 111 and the first discharge pipe 113.

In addition, the second fluid 6 flowing through the second inlet pipe 131 and the second discharge pipe 133 may be oil.

In this case, the fluid flowing through the electric boiler through the second inlet pipe 131 and the second inlet pipe 131 and the second discharge pipe 133 may be oil.

The second fluid 6 introduced and heated is introduced into the electric boiler 1 through the second inlet pipe 131 and heated, and then discharged through the second discharge pipe 133 to the floor of the residence (2). Circulates and can be used for heating, etc.

When the second fluid 6 used for heating is introduced into the electric boiler 1, the temperature is lower than the temperature when the second fluid 6 is discharged, and gasification may occur in the second fluid 6 and gas may be discharged. At this time, the produced gas may be discharged to the outside through the gas discharge pipe 230 connected to the upper end of the case 3.

The controller 4 may be installed on the upper end of the case 3, and through this, the circulation pump 112 and the power supply unit 730 may be controlled. That is, the inflow and discharge of the fluids 5 and 6 can be controlled, and the temperature and water level of the electric boiler 1 installed inside the case 3 can be controlled through the controller 4.

The power supply unit 730 may be installed outside the case 3 and connected to an end of the carbon rod 710 inserted into the outer surface of the housing unit 10 formed therein. Through this, the carbon rod 710 may be heated.

2 is a view showing the inside of the case of the electric boiler shown in FIG.

Referring to FIG. 2, the case 3 may include a heat preventing material 7, a housing 10, a gas tank 20, and a heating unit 70.

The heat prevention material 7 may be attached to the outer surface of the housing 10. The heat-preventing material 7 may be mainly used as an insulation material to block heat or a sound insulation material to absorb sound.

For this reason, the heat-preventing material 7 is attached to the front of the housing unit 10, and the inside of the electric boiler 1 is heated to increase the temperature of the housing unit 10, thereby preparing for a safety accident.

The housing unit 10 may include a first housing 110 and a second housing 130. In this case, the first housing 110 and the second housing 130 may have a rectangular parallelepiped shape and may store fluids having different specific heat therein.

For example, the fluid stored in the first housing 110 may be water, and the fluid stored in the second housing 130 may be oil. Since oil has a larger temperature variation than water, the temperature of the second housing 130 may be higher.

3 is a view showing a modified example inside the case shown in FIG. 2, and FIG. 4 is a view showing a cross-section of the housing portion shown in FIG. 3.

3 and 4, a heat exchange unit 30 may be included between the first housing 110 and the second housing 130.

The heat exchange part 30 may have the same shape as the housing part 10, and may be installed between the first housing 110 and the second housing 130.

In this case, the heat exchange unit 30 may be made of metal or earthenware, which is a material capable of storing more heat than the first housing 110 and the second housing 130.

As a result, the heat exchange unit 30 receives and stores heat from the first housing 110 and the second housing 130 and transfers the heat to the first housing 110 and the second housing 130 again. It is possible to prevent the rapid reduction of the heat of (10), thereby increasing the thermal efficiency.

At the bottom of the housing part 10, the inlet pipes 111 and 131 through which the fluid is introduced and the discharge pipes 113 and 133 through which the fluid is discharged may be connected, whereby the fluid is discharged from the electric boiler 1 and again inside the electric boiler 1 Can be moved to. That is, the fluid can circulate through the residence and the electric boiler (1).

At this time, the first inlet pipe 111 and the first discharge pipe 113 may be connected to the lower end of the first housing 110, and the second inlet pipe 131 and the second discharge pipe 133 may be connected to the lower end of the second housing 130. ) Can be connected. In this case, the fluid that moves to the first inlet pipe 111 and the second discharge pipe 133 may be water, and may be used as hot water.

In addition, the fluid that moves to the second inlet pipe 131 and the second discharge pipe 133 may be oil, and may be a fluid that may have a higher temperature than the fluid that moves to the first housing 110, so that it can be used for heating, etc. I can.

At this time, the pipe circulating the residence 2 and the electric boiler 1 through the second inlet pipe 131 and the second discharge pipe 133 through which the second fluid 6 moves may be a closed pipe. 2 Since the loss of the fluid 6 is small, the second fluid 6 can be circulated for a long period of time.

In addition, when the second fluid 6 flowing into the second inlet pipe 131 circulates through the residence and flows into the electric boiler 1, the gas may be generated as the temperature decreases. Accordingly, the gas inlet pipe 210 is connected to the second inlet pipe 131 so that the vaporized gas can be injected into the gas tank 20 located at the upper end of the housing part 10 along the gas inlet pipe 210. .

The gas tank 20 may have a rectangular parallelepiped shape and may store gas. In addition, the gas inlet pipe 210 may be connected to the right side.

Due to this, the gas generated as the temperature of the oil decreases may move through the gas inlet pipe 210 and be introduced into the gas tank 20, and the introduced gas is a gas discharge pipe located at the upper end of the gas tank 20 ( 230). Due to this, gas generated due to temperature change of the oil may be removed.

The frame unit 50 may include a first inner frame 510 and a second inner frame 530. At this time, the first inner frame 510 and the second inner frame 530 may be formed in the first housing 110 and the second housing 130, respectively, to determine a movement path of the fluid.

At this time, the first fluid 5 flowing into and out of the first housing 110 may be water, and the second fluid 6 flowing into and out of the second housing 130 may be oil.

In addition, the fluids 5 and 6 may be introduced into the housings 110 and 130 through the circulation pumps 112 and 132 located in the inlet pipes 113 and 131, and the circulation pumps 112 and 132 are controlled by the controller 4 to control the housings 110 and 130. ) It may be introduced into the interior and pass through the inner frames 510 and 530.

The first inner frame 510 is formed inside the first housing 110 and may include a first vertical frame 511 and a first horizontal frame 513. The first vertical frame 511 may be formed to be spaced apart from the left side of the first housing 110.

Accordingly, a conduit through which the first fluid 5 can move may be formed due to the inner surface of the first housing 110 and the first vertical frame 511.

In addition, a first vertical hole 512 is formed at an upper end of the first vertical frame 511 so that the first fluid 5 may flow into the pipeline. The first fluid 5 moved to the pipe is discharged through the first discharge pipe 113 connected to the lower end of the pipe and may move to the residence 2.

In this case, the first vertical hole 512 may be formed to have a size capable of preventing rapid flow or the like generated while the first fluid 5 passes through the narrow passage.

In addition, the first vertical frame 511 and the first horizontal frame 513 may be vertically connected to the right side of the first vertical frame 511. That is, the left side of the first horizontal frame 513 may be connected to the first vertical frame 511, and the right side may be connected to the inner side of the first housing 110.

In this case, the first horizontal frame 513 may be formed in plural with a predetermined interval. In this case, the first horizontal frame 513 may be positioned at different intervals.

In this case, the carbon rod 710 may be inserted into a space with a wide gap between the first horizontal frames 513. Accordingly, the first fluid 5 passing between the first horizontal frames 513 may be heated.

The heated fluid is the first horizontal hole 514 formed in the first horizontal frame 513 as the temperature of the fluid that flows into the lower end by the convective motion of the fluid sinks down and the fluid that starts heating from the lower end increases. You can ascend through it.

For example, the first horizontal frame 513 may be formed to be spaced apart from the lower end of the first housing 110, and the carbon rod 710 is inserted between the first housing 110 and the first horizontal frame 513. I can. In this case, each of the first horizontal frames 513 may have first horizontal holes 514, and the first fluid 5 may rise while passing through the first horizontal holes 514.

In addition, a first horizontal frame 513b having a predetermined distance from the first horizontal frame 513a may be positioned. Due to this, a conduit through which the first fluid 5 moves may be formed.

A first horizontal hole 514a may be formed on the left side of the first horizontal frame 513a. For this reason, when the first fluid 5 is connected to the lower end and the first fluid 5 is introduced, it may be heated by the carbon rod 710 and introduced into the first horizontal hole 514a, and the first fluid 5 that is primarily heated is It may be moved between the 1 horizontal frame 513a and the first horizontal frame 513b.

In addition, it may be discharged through the first horizontal hole 514b formed on the right side of the first horizontal frame b513. That is, the first horizontal hole 514 may be formed in a zigzag shape.

At this time, the first fluid 5 discharged through the first horizontal hole 514b is again secondary by a carbon rod 710 positioned between the first horizontal frame 513 and the spaced first horizontal frame 513. In this case, the secondly heated first fluid 5 may move upward and repeat the same process as the first heating.

Accordingly, the raised first fluid 5 can be discharged through the first vertical hole 512 formed at the upper end, and the first fluid 5 discharged through the first vertical hole 512 is the first discharge pipe 113 ) Can be discharged.

Accordingly, the first fluid 5 having the highest temperature is located at the upper end of the first housing 110 and passes through the first vertical hole 512 and is discharged along the first discharge pipe 113 so that it can be used as hot water. have.

At this time, when the discharged first fluid 5 circulates through the residence 2 and flows into the first housing 110 through the first inlet pipe 111, the first housing 110 and the first inlet pipe ( The filter 115 installed between 111) can pass. For this reason, when the first fluid 5 circulates and flows back into the first housing 110, foreign substances and the like can be filtered out.

In addition, the heat transfer unit 90 is connected to the outer surface of the carbon rod 710 connected to the inside of the first housing 110 to reduce the fluid velocity of the first fluid 5, which may have a high flow rate, and 1 To heat the fluid 5, the first fluid 5 can be effectively heated by increasing the heat transfer area through the heat transfer unit 90.

The second inner frame 530 is formed inside the second housing 130 and may include a second vertical frame 531 and a second horizontal frame 533. The second vertical frame 531 may be formed to be spaced apart from the left side of the second housing 130.

Accordingly, a conduit through which the second fluid 6 can move may be formed due to the inner surface of the second housing 130 and the second vertical frame 531.

In addition, a second vertical hole 532 is formed at the upper end of the second vertical frame 531 so that fluid may flow into the pipeline. The second fluid 6 moved to the pipe may be discharged through the second discharge pipe 133 connected to the lower end of the pipe to move to the residence. In addition, the second vertical frame 531 and the second horizontal frame 533 may be vertically connected to the right side of the second vertical frame 531.

That is, the left side of the second horizontal frame 533 may be connected to the second vertical frame 531, and the right side may be connected to the inner side of the second housing 130.

In this case, the second vertical frames 531 may be formed in a plurality with a predetermined interval, and the second horizontal frames 533 may be positioned with different intervals. In this case, the carbon rod 710 may be inserted into a space with a wide gap between the second horizontal frames 533. Due to this, the second fluid 6 can be heated.

The heated second fluid 6 may rise by passing through the second horizontal hole 534 as the temperature of the cold fluid flowing into the lower part by convective motion sinks down and the fluid starting to be heated from the lower end increases. .

For example, the second horizontal frame 533 may be formed to be spaced apart from the lower end of the second housing 130, and the carbon rod 710 is inserted between the second housing 130 and the second horizontal frame 533. I can. In this case, each of the second horizontal frames 533 may have second horizontal holes 534.

In addition, a second horizontal frame 533b having a predetermined distance from the second horizontal frame 533a may be positioned. Due to this, a conduit through which the second fluid 6 moves may be formed.

A second horizontal hole 534a may be formed on the left side of the second horizontal frame 533a. Accordingly, when the second fluid 6 is connected to the lower end and the second fluid 6 is introduced, it is heated by the carbon rod 710 and may be introduced into the second horizontal hole 534d, and the first heated second fluid 6 is 2 It may be moved between the horizontal frame 533a and the second horizontal frame 533b.

In addition, it may be discharged through the second horizontal hole 534b formed on the right side of the second horizontal frame 533b. That is, the second horizontal hole 534 may be formed in a zigzag shape.

At this time, the second fluid 6 discharged through the second horizontal hole 534b is again secondary by a carbon rod 710 positioned between the second horizontal frame 533 and the spaced second horizontal frame 533. In this case, the second fluid 6, which has been secondarily heated, may move upward and repeat the same process as the first heating.

Accordingly, the raised second fluid 6 can be discharged through the second vertical hole 532 formed at the upper end, and the second fluid 6 discharged through the second vertical hole 532 is the second discharge pipe 133 ) Can be discharged.

The fluids 5 and 6 may be heated by a plurality of carbon rods 710 inserted into the outer holes 120 formed on the right side of the first housing 110 and the second housing 130.

The heating unit 70 may include a carbon rod 710 and a power supply unit 730.

The carbon rod 710 may be connected to a plurality of outer holes 120 formed on right sides of the first housing 110 and the second housing 130. Accordingly, the fluid stored in the first housing 110 and the second housing 130 can be heated.

The carbon rod 710 can be inserted into the outer hole 120 formed on the right side of the housing part 10, and the carbon rod 710 connected to the outer hole 120 uses a nut 731 on the outer surface of the housing part 10 Can be fixed. In this case, the carbon rod 710 may be installed horizontally with the lower surface of the housing unit 10.

In addition, the right end of the carbon rod 710 fixed with the nut 731 is connected to the power supply unit 730 to supply power to the carbon rod 710 to heat the carbon rod 710.

For this reason, when the carbon rod 710 is heated, the inflowing fluids 5 and 6 flow into the lower end of the housing 10, and the heated fluids 5 and 6 may move upward due to convection. .

The carbon rod 710 may include carbon fibers (not shown) therein. Carbon atoms constituting the carbon fiber are formed in the form of hexagonal ring crystals along the length of the fiber, and are characterized by strong strength.

In addition, it has a feature of excellent conductivity. At this time, when the current passes through the carbon fiber, light in the far-infrared wavelength band is generated from the carbon fiber.

Through this, it is possible to heat the fluids 5 and 6 moving inside the housing 10.

The carbon fiber inside the carbon rod 710 can be connected to the electric wire formed on the right side of the housing part 10, so that the electric current from the power supply unit 730 is supplied through the electric wire, and the supplied current passes through the electric wire and the carbon rod 710 It moves to the carbon fiber.

When electric current flows through the carbon fiber, thermal energy is generated due to the resistance of the carbon fiber. Through this, the carbon rod 710 may transfer thermal energy to the surrounding fluids 5 and 6 to heat the fluids 5 and 6 in the form of convection and conduction. In this case, a heat transfer unit 90 extending while surrounding the carbon rod 710 in the longitudinal direction of the carbon rod 710 may be positioned.

The transmission body 900 may have a cylindrical shape, and may extend in the longitudinal direction of the carbon rod 710 while surrounding the carbon rod 710. By heating the carbon rod 710, the transmission body 900 may be heated. The transfer body 900, which may have an area larger than that of the carbon rod 710, increases an area capable of transferring heat to the fluid 2, so that heat can be more efficiently transferred to the first fluid 5.

In this case, a protruding member 910 may be formed that is formed in an outward direction from the outer surface of the transfer body 900 to increase the heat transfer area.

The protruding member 910 may include a first inclined surface 911, a second inclined surface 913, and a contact portion 915.

The first inclined surface 911 and the second inclined surface 913 may be formed in an outward direction on the outer surface of the transmission body 900 and may have a predetermined angle. In this case, the first inclined surface 911 may be inclined toward the second inclined surface 913, and the second inclined surface may be formed while inclined toward the first inclined surface 911.

Accordingly, the first inclined surface 911 and the second inclined surface 913 may contact each other and the contact portion 915 may be formed.

That is, when the contact portion 915 is formed while the first inclined surface 911 and the second inclined surface 913 are in contact with each other, the shape of the cross section may be triangular.

In addition, the first inclined surface 911 and the second inclined surface 913 may be formed along the transmission body 900 at a predetermined interval in the longitudinal direction of the carbon rod 710. In this case, the angle between the first inclined surface 911 and the second inclined surface 913 may be an acute angle.

Further, the plurality of protruding members 910 including the first inclined surface 911 and the second inclined surface 913 may be formed along the transmission body 900 in the same length and direction as the carbon rod 710.

At this time, the protrusion member 910 formed along the pillar has a gap formed between the protrusion members 910 so that the first fluid 5 may pass between the gaps. The heat efficiency of the heated carbon rod 710 is increased through the transfer body 900, and the contact part 915 may be connected to the heat transfer member 930. Through this, the area of heat transferred to the first fluid 5 is increased, so that the fluid can be heated more quickly.

The heat transfer member 930 may extend in the longitudinal direction while surrounding the outer surface of the transfer body 900, and may be made of a material having high heat conductivity.

In this case, the heat transfer member 930 may be a thin wire made of an alloy of nickel, tin, or chromium having a high thermal conductivity. In addition, due to the heat transfer member 930, the flow velocity of the first fluid 5, which may have a high flow velocity, can be slowed down, so that when the first fluid 5 passes, it is possible to prevent the occurrence of vortex or rapid flow.
