2 is a schematic front view showing a hot water boiler to which a heating heater (H) according to the present invention is applied, and FIG. 3 is a perspective cutaway view showing a hot water boiler to which a heating heater (H) according to the present invention is applied.

As shown in FIGS. 2 and 3, the hot water boiler to which the heater H according to the present invention is applied has a water supply port T1 and a recovery port T2 and a power supply unit C1 controlled by the controller C. ) Includes a tank (T) accommodating hot water boiled through a heating heater (H) driven by a power source.

A hot water pipe (B) for raising the temperature of the room by circulating hot water through a circulation pump (P) may communicate with the water supply port (T1) and the recovery port (T2), and tap water when the hot water in the tank (T) is insufficient. Of course, water supply pipes in US cities to fill the water supply can be communicated.

The heating heater (H) applied to the hot water boiler according to the present invention is connected to the frame (F) embedded in the tank (T) and the power cable (C10) for supplying power to the power supply unit (C1) through the connecting means (70). It may include a carbon fiber yarn heating cable (Q) wound around the frame (F) while being connected.

The carbon fiber yarn heating cable (Q) is prepared to actively use the heat generated by the carbon fiber yarn (Q1) covered with the fiber yarn coating (Q2). More specifically, in the case of a normal nickel-chrome wire, time is As time passes, the temperature increases proportionally, so it inevitably takes some time to heat up to high temperature. However, carbon fiber yarn (Q1) reaches high temperature heat immediately when power is supplied, guaranteeing thermal efficiency and controlling temperature. It is also easy and can be usefully applied to the present invention.

At this time, the fiber yarn covering (Q2) is pre-covered with heat-resistant glass fiber or mica wire of the United States with the carbon fiber yarn (Q1) at the center, followed by silicone resin and Teflon resin. Realization of insulation and waterproofing at the same time Of course you can.

In addition, the power cable (C10) connected to the power supply unit (C1) and connected to the carbon fiber yarn heating cable (Q) through the connection means (70) is centered on the power core wire (C11) made of copper, nickel or copper-nickel mixture. It can be placed on the wall and covered with Teflon resin to realize insulation and waterproofing as well as smooth supply of power.

Specifically, the heating heater (H) applied to the hot water boiler according to the present invention considers the flexibility of the carbon fiber yarn heating cable (Q) and embeds the frame (F) in the tank (T) in order to use it at the same time. In a state where the carbon fiber yarn heating cable (Q) is wound around the frame (F) to maintain a dense state, power is supplied from the power supply unit (C1) through the power cable (C10) to quickly boil hot water by concentration of heat. ring is possible, and furthermore, by completely immersing the carbon fiber yarn heating cable (Q) into the hot water in the tank (T) using the insulation and waterproofing by the fiber yarn covering (Q2) covered with the carbon fiber yarn (Q1), By realizing safe boiling, the boiling of hot water for hot water supply, that is, for indoor heating, is made faster and easier.

In this way, the hot water boiled by the heat of the carbon fiber yarn heating cable (Q) wound around the frame (F) is circulated from the water inlet (T1) to the hot water pipe (B) and the return pipe by the circulation pump (P). Indoor heating can be provided.

The tank (T) is in direct contact with the outside air, and the thermal efficiency is inevitably lowered. Since the deformation of the tank T may be caused by this, in the present invention, the carbon fiber yarn heating cable Q can be densely wound around the vertical rods F3, while the carbon fiber yarn heating cable Q is the tank ( The both side support pieces (F4) protruding outward from both sides of the upper frame (F1) so that they can be spaced apart from T) can be supported by elastically contacting both inner sides of the tank (T), and at the same time, the carbon fiber yarn heats up By allowing the frame (F) with the cable (Q) wound to be fully submerged in the hot water in the tank (T), it is easy to assemble and disassemble the frame (F) and secures stable heat generation of the carbon fiber yarn heating cable (Q). that made it possible

Preferably, in the present invention, the connection means 70 together with the carbon fiber yarn heating cable Q can be fully submerged into the hot water of the tank T.

In general industrial fields, electrically connected parts are thoroughly placed outside the liquid for insulation and waterproofing, but in the present invention, the connection means 70 is rather completely submerged into the hot water of the tank T.

When power through the power cable C10 is supplied to the carbon fiber yarn heating cable Q, the resistance of the power cable C10 depends on the difference between the resistance value of the power core wire C11 and the resistance value of the carbon fiber yarn Q1. Electric energy can be converted into thermal energy by the carbon fiber yarn heating cable (Q). At this time, the connection means (70) for connecting the power core wire (C11) and the carbon fiber yarn (Q1) has a difference in resistance value between them. Depending on the overload, rapid heat generation and instant bursting of the connection area are bound to occur. In the present invention, the connection means 70 is completely submerged in the hot water in the tank T, so that the The environment and the connection means 70 have the same conditions, that is, the same conditions in hot water, so that the sudden overload at the connection part due to the difference in resistance value can be overcome when power is supplied, so that the connection means 70 This is to ensure longevity while preventing bursting in advance.

Figure 4a is an exploded perspective view showing the connection means 70 applied to the heating heater (H) according to the present invention, Figure 4b is a cross-sectional view showing the connection means 70 applied to the heating heater (H) according to the present invention.

As shown in FIGS. 4A and 4B, the connecting means 70 applied to the heating heater H according to the present invention connects the power core wire C11 wrapped with the power sheath C12 of the power cable C10 to a carbon fiber yarn. A sleeve 72 that holds the power sheath (C12) and the fiber sheath (Q2) together while being inserted into the carbon fiber yarn (Q1) wrapped with the fiber yarn sheath (Q2) of the heating cable (Q) , With the sleeve 72 at the center, it includes a sealing portion 73 that is covered while being fused from the power source coating C12 to the fiber yarn sheath Q2.

The power core wire (C11) is inserted into the carbon fiber yarn (Q1) so that the power core wire (C11) can be wire-connected within the strand of the carbon fiber yarn (Q1), and at the same time, the power sheath (C12) and the fiber yarn sheath (Q2) ) are in close contact with each other so that arc discharge that can occur when power is supplied is covered as much as possible with the power coating (C12) and the fiber yarn coating (Q2), and at the same time integrated and protected as the sleeve 72, so that the power core wire ( C11) and the carbon fiber yarn (Q1) can be more closely connected to each other, and furthermore, from the power covering (C12) to the fiber yarn covering (Q2), the sealing part 73 can be fused while being covered In addition to thorough covering of arc discharge, it is possible to maximize insulation and waterproofing by more reliably preventing penetration of hot water.

Preferably, the power source coating (C12) and the fiber yarn coating (Q2) each have a corrosion surface (M), and the sealing portion 73 has the sleeve 72 in the center, and the power source coating (C12) has a corrosion surface (M) From the fiber yarn covering (Q2) to the corrosion surface (M) so that it can be covered while being fused.

The outer skin of the power coating (C12) and the outer skin of the fiber yarn coating (Q2) may be made of Teflon resin for insulation and waterproofing and prevention of damage due to external contact, and the sealing part 73 may apply silicone resin. , Teflon resin and silicone resin are heterogeneous properties due to different materials, and gaps occur between them during sealing, which inevitably deteriorates the waterproof function. With the sleeve 72 at the center in a state where Q2 has a corrosion surface M, silicon from the corrosion surface M of the power supply coating C12 to the corrosion surface M of the fiber yarn coating Q2 It is made to be covered by fusing resin to realize more thorough waterproofing.

At this time, the sleeve 72 is spaced apart and compressed at one point and the other point on the circumference to protect the carbon fiber yarn Q1 in the center while locally holding both sides of the fiber yarn covering Q2. Spaced bonding portion 72a In addition, the sleeve 72 is compressed as a whole and includes an overall compression portion 72b that holds the power core wire C11 at once while pressing the power sheath C12 at once, the carbon fiber yarn having a weak structure (Q1 ) is protected as the spaced crimping portion 72a, while the power core wire C11 made of copper, nickel, or copper-nickel alloy can be closely held through the entire crimping portion 72b, so that the carbon fiber yarn The protection of (Q1) and the connection force of the power core line (C11) can be satisfied at the same time.

Preferably, the connection means 70 includes a connection piece 74a containing the power core wire C11 and a connection pin 74b extending from the connection piece 74a and inserted into the carbon fiber thread Q1. A terminal 74 may be further included, and the connection terminal 74 may be made of molybdenum having excellent electrical conductivity.

The difference in resistance between the power core wire (C11) and the carbon fiber yarn (Q1) while considering the fact that it may be difficult to insert the power core wire (C11) into the carbon fiber yarn (Q1) if it is flexible or made of multiple strands. In order to eliminate the phenomenon of arc discharge in advance when supplying current according to the current, after wrapping the power core wire (C11) with a connection piece (74a) made of molybdenum with excellent electrical conductivity, insert the connection pin (74b) into the carbon fiber thread (Q1). It minimizes the electrical resistance value at the part where the power core wire (C11) and the carbon fiber thread (Q1) are connected by inserting it, and at the same time, it also facilitates the assembly work between them, so that both electrical functionality and work productivity can be satisfied.

It is preferable because it can rapidly penetrate into, and it can ensure electrical stability through high conductivity, and is chemically quite stable (firing point in air is stable at about 500 ~ 600 ℃), graphite 97 ~ 99wt% as 1 It is to be able to mix with ~3wt% of graphene. At this time, if graphite is less than 97wt%, it is not preferable because chemical stability and electrical conductivity are not sufficient, and 99wt% of graphite is graphene for optimized electrical performance It is set as a limit value corresponding to 1 wt% of.

As a binder, Epoxide Resin has strong adhesive strength and excellent chemical resistance, heat resistance, and water resistance, and actively overcomes the exothermic temperature of the carbon fiber yarn (Q1) while connecting the connection pin (74b) and the carbon fiber yarn (Q1) to each other.
