BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view of a preferred embodiment of a temperature-regulated circulation boiler according to the present invention; Fig. I can understand it well.

2 is a structural view showing a temperature-regulated circulation type boiler apparatus according to the present invention.

2, the temperature-regulated circulation boiler according to the present invention includes a boiler B driven by the control of the controller C, a supply pipe Pa supplied with the heating water from the boiler B, A circulation pipe Pb for supplying and circulating the heating water from the supply pipe Pa and a recovery pipe Pc for recovering the heating water from the circulation pipe Pb and injecting the heated water through the circulation pump H into the boiler B .

When the heating is selected according to the control of the controller C, the heating water is heated by the boiler B and supplied through the supply pipe Pa. After heating the indoor floor of each room through the circulation pipe Pb, Pc) to be circulated to the boiler B (at this time, the hot water supply is a general technique, so that no explanation is given and it is not shown).

The controller C includes a temperature sensor S1 that senses the temperature of the boiler B according to the first aspect of the present invention and the controller C determines whether the temperature of the temperature sensor S1 sensed by the boiler B at the time of heating, The circulation pump H can be stopped while the temperature of the temperature sensor S1 sensed by the boiler B becomes lower than the set heating temperature.

When the heating is selected according to the control of the controller C, the circulation pump H is simultaneously driven so that the heating water in the boiler B is directly supplied to the supply pipe Pa. In this case, Not only is the time required for raising the room temperature to be increased but also the cold heating water remaining on the circulation pipe Pb is directly introduced into the boiler B through the recovery pipe Pc, The heating water in the heat exchanger (B) also takes a long time to heat.

In consideration of such a problem, in the first aspect of the present invention, when the indoor heating set temperature is selected through the controller (C) during heating, the controller (C) compares the heating set temperature with the temperature of the boiler (B) The circulation pump H is driven and the circulation pump H is stopped so that the heating water in the boiler B can be supplied through the supply pipe Pa in a state in which the heating water is sufficiently warmed, Not only the heating water in the room B can be quickly heated, but also the sufficiently heated water can be supplied to the circulation pipe Pb, whereby the room temperature can be increased more rapidly.

When the desired heating temperature, which is the desired temperature of each room, is different, the controller C recognizes the average value of the different heating set temperatures as the final heating set temperature and determines the temperature of the boiler B sensed by the temperature sensor S1 So that they can be compared.

At this time, the controller C controls the driving and stopping of the circulation pump H within a range of ± 5 ° C based on the heating set temperature, so that the circulation pump H is not driven and stopped excessively sensitively To ensure its longevity.

On the other hand, according to the second aspect of the present invention, when the temperature sensed by the boiler B during heating by the control of the controller C becomes equal to or higher than the circulating operating temperature, the circulation pump H is driven, while the boiler B (S2) for stopping the operation of the circulation pump (H) when the sensed temperature becomes lower than the circulation operating temperature.

In the second aspect of the present invention, the temperature regulating sub-controller (S2) under control of the controller (C) drives the circulation pump (H) directly according to the temperature of the boiler (B) So that the heating water in the boiler B can be supplied through the supply pipe Pa in a sufficiently warmed state to the circulation operating temperature so that the heating water in the boiler B can be quickly heated It is possible to supply the sufficiently heated water to the circulation pipe Pb, whereby the room temperature can be increased more quickly.

Particularly, according to the second aspect of the present invention, if the heating is set regardless of the heating temperature under the control of the controller (C), the circulating pump (H) is driven and stopped So that complicated design of the controller C is not required as a simple control of the circulation pump H and accordingly, the failure phenomenon of the controller C can be significantly reduced.

The circulating operation temperature of the temperature-regulating sub-controller S2 can be set differently according to the season, and the driving and stopping of the circulating pump H can be controlled within a range of ± 5 ° C based on the seasonally determined temperature If the circulation operation temperature of fall season is set to 20 ° C or the circulation operation temperature of winter season is set to 30 ° C, the operation and stop of circulation pump (H) can be controlled in the range of 15 to 25 ° C in fall or 25 to 35 ° C in winter) So that the phenomenon that the circulation pump H is driven and stopped too sensitively is eliminated so that the failure rate can be remarkably reduced.

FIG. 3A is a perspective view showing a boiler B applied to a temperature-adjusted circulating boiler according to the present invention, FIG. 3B is an exploded perspective view showing a boiler B applied to a temperature-adjusted circulating boiler according to the present invention, 3C is a longitudinal sectional view showing a boiler B applied to the temperature-adjusted circulating boiler apparatus according to the present invention.

At this time, the first power cable 31a and the second power cable 31b are connected to the first lead wire 14a and the second lead wire 14b, respectively, and then covered with the ceramic cap 32, And the electrical energy supplied through the first power cable 31a and the second power cable 31b is supplied to the heat resistant glass tube 12 The carbon fiber yarn 11 in the heat-resistant glass tube filled with the inert gas is converted into heat energy so that the heating water can be intensively heated in the body 40.

The heat generating rod 10 is connected to the first connection terminal 13a and connected to one end of the carbon fiber yarn 11 and the connection wire 16a connected to the second connection terminal 13b while being connected to the heat resistant glass tube 12, And a center line 16b sandwiched between the upper and lower ends of the carbon fiber yarn 11. The center line 16b is connected to the other end of the carbon fiber yarn 11, And a tension supporter 19 for elastically supporting the inner circumferential edge of the heat resistant glass tube 12 and centering the center line 16b in the heat resistant glass tube 12 and preventing the center line 16b from flowing.

The center line 16b can be centered without being eccentric in the heat resistant glass tube 12 by the tension supporting portion 19 elastically supported on the heat resistant glass tube 12, It is possible to minimize damage to the carbon fiber yarn 11 due to contact when the carbon fiber yarn 11 is heated due to the direct contact with the inner periphery of the carbon fiber yarn 11. In addition, the center line 16b can be moved up and down, Even if the carbon fiber yarn 11 is subjected to the operation while the heat-resistant glass tube 12 is standing up when the crimping portion 12a is provided with the first connection terminal 13a and the second connection terminal 13b as the center, , The phenomenon of being lowered from the heat-resistant glass tube 12 by the weight of the welded portion 17 and the center line 16b can be overcome, and the work of giving the pressed portion 12a can be implemented more easily, .

More specifically, the tension supporting portion 19 includes a winding portion 19a wound around the center line 16b, a wire 19b bent downwardly in the diagonal direction from the lower end of the winding portion 19a, 19a of the heat resistant glass tube 12 and bent downward from the upper end of the heat resistant glass tube 12 so as to be folded downward and supported by the heat resistant glass tube 12 with one wire 19b and the other wire 19c centered on the center line 16b, And the other wire 19c and the other wire 19c when the carbon fiber yarn 11, the insulation 17 and the center line 16b are inserted into the heat resistant glass tube 12, While the carbon fiber yarn 11, the insulation 17 and the center line 16b are elastically supported by the elastic supporting force of the tension supporting portion 19 during the applying operation of the pressing portion 12a, ) Is prevented completely.

On the other hand, the fixing means 50 includes a flange 51 which is fixed to the top hole 40a and has a step 51a at its inner periphery and protrudes outward, and a flange 51 which is inserted into the flange 51 A pushing ring 53 that enters the flange 51 and contacts the O-ring 52 while being fitted in the heat generating bar 10 and the heat generating rods 10 While pushing the pushing ring 53 to reduce the O-ring 52 in the entering direction while passing through the through-holes 54a for passing through the through-holes 54a passing through the through holes 54a passing between the outer circumferences of the heat generating rods 10 and the inner circumferences of the flanges 51 And a fixture 54 screwed to the flange 51 for sealingly sealing the flange 51.

The heating rods 10 can be simply and quickly assembled to the body 40 by the fixing bodies 54 screwed to the flanges 51 and the pushing of the O- The gap between the heating rod 10 and the flange 51 can be further tightly sealed so that cold water is introduced through the recovery port 41 and then the hot water is discharged to the supply port 42. [ As a thorough prevention, safe and accurate operation can be ensured.

The heating bar 10 may further include an infrared ray blocking coating portion 15 which is coated on the surface of the heat resistant glass tube 12 facing the flange 51 and blocks the infrared ray emitted from the carbon fiber yarn 11 .

The infrared rays irradiated from the carbon fiber yarn 11 are blocked by the infrared ray blocking coating portion 15 so as not to affect the O-ring 52 made of rubber, silicone or synthetic resin, so that the O- Thereby protecting the heat-resistant glass tube 12 more securely and at the same time preventing leakage phenomenon more thoroughly, thereby assuring a service life.

Preferably, the infrared ray shielding coating part 15 is provided on the surface of the pressing part 12a and is exposed to the outside through the gap between the heat resistant glass tube 12 and the heat resistant glass tube 12 thermocompressed along the pressing part 12a The first lead wire 14a and the second lead wire 14b.

The heat-resistant glass tube 12 manufactured by blower molding or metal molding is received with the carbon fiber yarn 11 and the like in a state where one side is opened, filled with inert gas after vacuum, and then connected to the first connection terminal 13a and the second connection The open end of the terminal 13b is thermocompression-bonded to provide the crimping portion 12a. At this time, the crimped portion 12a to be thermally pressed must have a clearance, and the first lead wire 14a And the second lead line 14b are also inevitably exposed to the gap. In this case, the light leakage, that is, the infrared rays, must escape through the gap.

In the present invention, the infrared shielding coating portion 15 coated on the surface of the crimping portion 12a and the gap around the first lead wire 14a and the second lead wire 14b so as to thoroughly block the infrared rays The life of the O-ring 52 made of rubber, silicone, or synthetic resin can be maximized.

More specifically, the infrared shielding coating portion 15 comprises 40 to 50 wt% of acrylic resin, 10 to 15 wt% of titanium dioxide, 3 to 7 wt% of graphite, 10 to 15 wt% of silica beads, % Of calcium carbonate, 4 to 7 wt% of sodium silicate, and 5 to 8 wt% of carbon.

Acrylic resin is a generic name of a synthetic resin obtained by polymerization of acrylic acid and derivatives thereof, and a polymer of methyl acrylate and methyl methacrylate has been put to practical use. The acrylic resin has good chemical resistance, is resistant to water, acid, and alkali and has good electrical insulation and water resistance The present invention is applied to the main composition of the present invention. If it is 40 wt% or less, the electrical insulation and water resistance may be lowered. If it is 50 wt% or more, .

Titanium dioxide is used as a coating material with bitter dye, and it does not dissolve in water, hydrochloric acid, dilute sulfuric acid alcohol and other organic solvents. Especially, it is very stable with high hiding power not dissolving in acid. It is excellent in weatherability and chemical resistance, And is effective as an insulator. In the present invention, 10-15 wt% of titanium dioxide is applied. When it is 10 wt% or less, the acid is applied to the acid If the dissolving hiding power is lower than 15 wt%, mixing with the acrylic resin is not performed well, and in the present invention, 10 to 15 wt% of titanium dioxide is applied.

As a result, a phenomenon of cracking occurs after curing because of excessively hardness. Therefore, in the present invention, 6 to 8 wt% of calcium carbonate is applied.

Sodium silicate adjusts the mixed viscosity of acrylic resin, titanium dioxide, graphite, silica bead, calcium carbonate and carbon. For example, when the concentration is increased, the viscosity is raised. When the temperature is increased during mixing, the viscosity is lowered, In the present invention, 4 to 7 wt% of sodium silicate is applied. When the amount is less than 4 wt%, the viscosity is weakened to slow the curing after coating. When the amount is 7 wt% or more, In the present invention, sodium silicate is applied in an amount of 4 to 7 wt%.

In the present invention, carbon is applied in an amount of 5 to 7 wt%. When the amount is less than 5 wt%, infrared rays are difficult to block. When the amount is more than 8 wt%, carbon acts as a conductor, 8% by weight.

As described above, in consideration of the fact that the heat-generating rod 10 according to the present invention can be broken due to the nature of the heat-resistant glass tube 12 and that a tight seal is maintained to prevent leakage, It is coated on the surface of the heat-resistant glass tube 12 opposed to the flange 51, that is, opposed to the O-ring 52 in consideration of the fact that the O-ring 52 is fatal to infrared rays, so that infrared rays irradiated from the carbon fiber yarn 11 are blocked , 15 to 15 wt% of titanium dioxide, 3 to 7 wt% of graphite, and 10 to 15 wt% of an ultraviolet ray shielding coating portion 15, % Of silica beads, 6 to 8 wt% of calcium carbonate, 4 to 7 wt% of sodium silicate, and 5 to 8 wt% of carbon, so that the o-rings 52 ) To ensure the longevity of .

The heating bar 10 is fixed to the connecting line 16a while grasping the insulating pipe 17 to enlarge the gap between the first connecting terminal 13a and the second connecting terminal 13b And includes a spacing member 18.

When the first connection terminal 13a and the second connection terminal 13b are thermocompression-bonded at the end of the heat-resistant glass tube 12 with the first connection terminal 13a and the second connection terminal 13b centered, The first connection terminal 13a and the second connection terminal 13b may be separated from each other by the weight of the insulation 17 sometimes due to the displacement of the heat-resistant glass tube 12 during thermal compression, In order to solve such a problem, in the present invention, as the spacing member 18, the connection line 16a is fixed while holding the insulation 17, So that the gap between the first connection terminal 13a and the second connection terminal 13b can be uniformly opened.

Specifically, the spacing member 18 includes a wind plate 18c for winding up the insulation 17, a one-side spreading plate 18b that is spread out from the wind plate 18c and welded to each other and fixes the connection line 16a, And a spread plate 18c.

The other spreading plate 18c is welded to the middle of the one spreading plate 18b in a state where the length of the other spreading plate 18c is smaller than the length of the one spreading plate 18b The connection line 16a can be welded at the boundary between the end of the other spreading plate 18c and the one spreading plate 18b so that the connection line 16a can be welded to the other spreading plate 18b 18c and the one-side spreading plate 18b, it can be welded along the arc surface thereof, thereby enabling a more compact and more firmly fixed, thus ensuring a service life.

The first lead wire 14a and the second lead wire 14b have a first bent portion a and a second bent portion b which are bent in opposite directions to each other, The second power cable 31b can be prevented from short-circuiting due to contact between the first lead wire 14a and the second lead wire 14b.
