Description

[0001] The present invention relates to a heater installation structure for a hot water boiler,

The present invention relates to a heater installation structure of a hot water boiler, and more particularly, it relates to a heater installation structure of a hot water boiler, in which raw water and recovered water are rapidly heated in a single penetration portion by using a heater for DC power supply, Thereby suppressing the generation of electromagnetic waves and reducing adverse effects of the human body caused by electromagnetic waves.

Generally, a heating device used for a heating mat is composed of a heating water tank for storing heating water, a heater for generating heating water by heating heating water, a circulation pump for circulating hot water, and a heating pipe connected to the heating mat.

Such a conventional heating apparatus has a structure in which heating water stored in a heating water tank is supplied from a heater and heated to generate hot water, and the circulation pump is operated to circulate the heating water into a heating pipe.

However, the conventional heating apparatus circulates the heating water by using the circulation pump, so that the noise and the electromagnetic wave generated by the operation of the circulation pump are generated, and the life of the entire heating apparatus is shortened due to the failure of the circulation pump.

According to a prior art created to solve this problem, a circulation tube embedded in a heat dissipating member flowing through a circulation pipe in a heat dissipating member constituting a heating device is disclosed in Japanese Patent No. 10-0312643 entitled " Liquid Circulation Heating Device " A pressure buffering means for buffering the pressure of the liquid expanded by the operation of the heating means to enable circulation of the liquid, and a pressure buffering means provided between the heating means and the pressure buffering means And the second backflow prevention means is provided so as to face the first backflow prevention means. The fluid flowing through the circulation pipe in the heat releasing member constituting the heating device is heated by the heat transfer, A technique for absorbing the pressure generated when natural circulation is known is known.

However, since the liquid circulation type heating apparatus of the prior art circulates by the expansion force generated by heating the liquid, a considerably high pressure is generated in the circulation tube, and thus a pressure buffer for buffering the pressure is required separately.

In order to solve this problem, according to Korean Patent No. 10-0803282, the raw water is supplied from the heater, and the heating pipe is automatically circulated in a state where hot water and steam are mixed due to the expansion force of the generated steam. And a heating apparatus using hot water and steam, which does not generate noise and electromagnetic waves due to circulation of hot water and steam.

This prior art is based on a PTC (Positive Temperature Coefficient) method in which raw water introduced from a raw water tank is connected to the outside of a penetration portion when passing through a penetration portion (generally, PTC is used at a constant voltage of 60HZ, And a circulation system for recovering the hot water circulating in the heating pipe to the inside of the raw water tank is adopted. First, since the raw water inside the penetrating portion is heated from the outside of the penetrating portion by heat transfer from the outside of the penetrating portion, The heating time of the raw water circulated in the heating pipe is slowed down and the PTC heater is usually heated using an AC current. Therefore, the electromagnetic wave harmful to the AC current supply, that is, It is evil that electromagnetic waves are introduced into water and electromagnetic waves are applied to human body through heating pipes. Inevitable incense, leans PTC heater has a problem in that the heat transfer efficiency significantly decreases because of the structure, so that the ceramic heating voltage is applied to the metal foil electrode that extends the heating starting time are not comfortable with the rapid heating in progress. In this case, there is a problem in that electric power is wasted due to excessive power consumption, and the assembly process is complicated due to the complicated structure, resulting in an increase in manufacturing cost of the device.

Another prior art, which has the disadvantage of this structure, also has the disadvantage of the prior art described in Korean Patent No. 10-1038576.

Therefore, not only the heating time is reduced but also the heating area is widened by rectangular contact In addition, since the inside of the penetration portion is heated at the same time as the DC current is supplied to the heater, the heating pipe is rapidly heated to provide ease of use. In particular, since the DC current is supplied to the heater, the electromagnetic wave is not generated, It has the effect of providing hot water boiler.

In addition, the present invention has the effect of reducing the manufacturing cost by greatly reducing the assembly process by connecting the adapter including the check valve and the penetrating part by reducing the electricity cost.

The present invention is characterized in that the raw water tank 10 is disposed apart from the adapter unit 30 and the penetration unit 40 so as to be disposed below the installation height of the raw water tank 10, 30 and the penetrating portion 40 and the connecting pipe 50 and the return pipe 12 are not introduced into the raw water tank 10 side. The adapter portion 30 and the penetrating portion 40 may be provided on the side of the bottom surface of the raw water tank 10 or on the bottom surface of the case in which the raw water tank 10 is not shown.
The present invention is also applicable to an air discharge induction filter (for example, a cotton fabric with fine holes, leather, etc.) inserted into a connection pipe 80 sandwiched between a radiating pipe 70 provided between one side of a heating pipe 20 and a return pipe 12 The air bubbles through the air discharge pipe 100 are connected to the raw water tank 100 via the air discharge pipe 100.

The heater unit 60 includes a plate-like plate 62 (63) at both ends of a planar heating element 61 made of carbon islands or carbon nanotubes (CNT) or VGCF (vapor grown carbon fiber) or carbon nanohorn or fullerene in the center, (+) And negative (-) terminals are formed on both ends of the thin plates 62 and 63 to supply a direct current. The planar heating element 61 may be formed of activated carbon fiber. Alternatively, the planar heating element 61 may be formed by injection molding a flexible resin mixed with carbon fibers, and the resistance value can be adjusted according to the carbon content.

In the above, 36 W is generated by applying a direct current 5 A X voltage 12 V to the copper thin plates 62 and 63, or 36 W is generated by applying a direct current 3A X voltage 24 V so that the temperature is not raised by 150 ° C. or more desirable.

7, the heater unit 60 may be heated by being fitted into a fitting member 44 formed integrally below the penetrating unit 40 to heat and recover raw water and recovered water in the penetrating unit 40 .

5, the heater 60 is heated in a state where the thin plates 62 and 63 are in surface contact with the inner side surface of the insertion groove 41 of the penetration portion 40, So that the heat generated by the heater can be efficiently performed.

When the direct current (+) (-) is supplied to each of the copper thin plates (electrode portions) 62 and 63 of the heating portion 60, the inside of the planar heating element 61 made of carbon fiber or the like Heat is generated through the surface area of the carbon resistance and is conducted to the thin copper plates 62 and 63, thereby generating heat. Accordingly, the heat generated by the heating unit 60 is generated in a state of being fitted in the insertion groove 41 of the penetrating portion 40, and the heat is generated in a state of being in surface contact with the inner side surface of the insertion groove 41. Therefore, So that generation of electromagnetic waves is suppressed because heat is generated by the supply of the DC current.
The insertion groove 41 of the penetrating portion 40 is formed by forming a groove in the penetrating portion 40 as shown in FIG. 5 and the penetrating portion 40 is formed by the insertion groove 41, The area inside the penetrating portion 40 is formed to be wider than the diameter of the return pipe 12 so that when the hot water inside the penetrating portion 40 is heated and expanded, the hot water in the penetrating portion 40 has a diameter The water in the penetrating portion 40 can always flow out to the side of the return pipe 12 on the side of the narrow connecting port 50. Even if the hot water in the penetrating portion 40 is moved to the return pipe 12 side, So that the reheat can be thermally expanded by the heating of the heater 60. The water staying at this time is hot water which is always replaced by the circulation of hot water.

In this state, if the target temperature is the target temperature by the operation of the control circuit portion (not shown) due to the temperature sensing of the temperature sensor 130, the heating is stopped.
The temperature of the hot water circulating in the heating pipe 20 is lowered to a predetermined temperature or below and the temperature of the temperature sensor 130 of the heater unit 60 is lowered by the operation of the heater unit 60, The pressure generated by the heating and expanding of the hot water in the penetration portion 40 and the adapter portion 30 is transmitted to the inner side of the adapter portion 30, The check valve 120 is closed and a pressure is applied to the connection port 50 so that the hot water in the adapter 30 and the penetration unit 40 is rapidly heated while the return pipe 12 And the hot water through the return pipe 12 is supplied to the inside of the adapter unit 30 through the protruding penetration portion 32 of the adapter unit 30, The valve 120 is opened to pass through the penetration portion 40 And is continuously circulated through the recovery pipe 12 again. Therefore, circulating warm water is circulated without being introduced into the raw water tank 10, so that only the hot water in the adapter unit 30 and the penetrating unit 40 can be rapidly heated without heating the raw water in the raw water tank 10, The hot water can be circulated in a state of not lowering the temperature of the hot water, the power consumption can be greatly reduced, and the hot water heating time can be greatly reduced.
If the circulating hot water is insufficient for the reason of steam generation or the like, the raw water in the raw water tank 10 is supplied to the inside of the adapter unit 30 through the raw water supply inlet pipe 11 and the protrusion penetration unit 31 So that the hot water in the penetration portion 40 is lowered to the set temperature or lower. As a result, when the temperature of the inside of the penetration portion 40 becomes lower than the set temperature, 60 are restarted to close the opened check valve 120 while heating the internal hot water to circulate the hot water to the connection port 50 side.
Therefore, the hot water circulated through the return pipe 12, the adapter unit 30, the penetrating unit 40 and the connecting port 50 can be prevented from flowing into the raw water tank 10, The circulation of the hot water is performed in a state in which the temperature of the hot water in the raw water tank 10 does not affect the raw water in the raw water tank 10 so that the temperature of the circulating hot water is prevented from being lowered so that the operation of the heater unit 60 is prevented So that the power waste due to the operation of the heater unit 60 can be greatly reduced.
In addition, since the heated hot water does not come into contact with the raw water in the raw water tank 10, the present invention can eliminate the bubble phenomenon that occurs when hot water is mixed with the water in the tank 10, It can be suppressed.
That is, in the hot water circulated to the inside of the recovery pipe 12 in the heated state, air bubbles are generated in the recovery pipe 12 due to the generation of steam, and the air contained in the hot water directly flows into the inside of the raw water tank 10 (Bubble) phenomenon does not occur in the raw water tank 10 because it is not supplied to the raw water, so that the noise due to the bubble phenomenon can be excluded. Furthermore, since the heated hot water does not come into contact with the raw water, Since the high temperature at which the hot water is boiled and transferred does not affect the raw water, the noise can be suppressed by eliminating the phenomenon that the raw water doubles the bubble phenomenon. The air bubbles included in the warm water that is lighter than the hot water are caused to flow to the air discharge pipe 100 as a bypass pipe and flow into the raw water tank 10, The air bubbles are only passed through the air discharge induction filter 90 provided inside the connection pipe 80 and the hot water is supplied to the protruding through portion 32 of the adapter portion 30 So that the temperature of the hot water can be prevented from being lowered.
In the configuration of the present invention, in order to circulate the hot water by heating and expanding the hot water staying inside the penetrating portion 40 having the inner space wider than the diameter of the return pipe 12, the penetrating portion 40 The circulation of the hot water is slowed down, for example, when the temperature of circulating hot water is lowered. At this time, The hot water in the return pipe 12 is stored in a larger quantity than the hot water staying in the return pipe 12 and the heated hot water is heated and expanded by the heater unit 60 so that the hot water can be heated quickly, Since the inner space is narrowed and the heat generating area is widened, the heating is performed more quickly, and the heated air is rapidly heated by the heated and inflated pressure, Since the hot water in the heat exchanger 12 is circulated while being heated, it is possible to shorten the hot water heating time and to reduce power waste. That is, in the present invention, a separate penetrating portion 40 is formed without providing a heater portion outside the return pipe 12 through which the hot water passes, so that even if the hot water is circulated through the return pipe 12, And the heated and expanded water is heated and expanded to recognize the return pipe 12 having the narrowed diameter of the heated and expanded pressure inside the penetrating portion 40 having a wide inner space as a nozzle, So that circulation of hot water can be performed more quickly. In particular, hot water is circulated in a state in which raw water in the raw water tank 10 is not heated.

In the case where the hot water boiler is operated for the first time, according to the present invention, the water inside the penetration portion 40 is heated and expanded by heating of the heater portion 60 to heat water while pushing water in the recovery pipe 12, Therefore, when the heating mat is operated, the hot water is heated within a very short time, thereby minimizing power waste due to hot water heating.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be understood that various variations and applications are possible.
