Description AUXILIARY HEATING DEVICE OF BOILER

Technical Field

[1] The present invention relates to an auxiliary heating device of a boiler, which is mounted on a side of a circulating pipe of a boiler used at homes or in a small-sized agricultural greenhouses to preheat circulated hot water once more, thereby achieving an energy saving effect of 80% to 90% out of energy efficiency of 100% by reducing an operation period of the boiler. Background Art

[2] In general, a boiler is a heating system, which burns fuel to heat water(H₂O) and circulates the heated water through a passageway of an excel pipe through a circulation motor to heat a room, a living room and the like.

[3] A typical boiler heats a metal material with combustion heat in order to heat water to a predetermined temperature by thermal conduction of the metal material. However, the typical boiler causes a great loss of fuel since the combustion heat, which is not used for the thermal conduction of the metal material, is exhausted through an exhaust pipe as it is.

[4] Furthermore, improved boilers each having a heating device mounted on a circulating pipe to heat circulating water have been disclosed. For instance, Korean Utility Model Registration No. 20-0185148 discloses an auxiliary heating device for a regenerative type night electric boiler, which supplies circulating water of a pipe body into an inner thermal storage tank 3 of the regenerative type night electric boiler (A) through a water supply pipe 2 using a circulating pump 1 so that regenerated circulating water is heated by a general boiler (B) through a feed pipe 4 or heats the inside of a room while passing through a discharge pipe 5, comprising: an auxiliary pipe 7 mounted between the water supply pipe 2 and the feed pipe 4 and having an auxiliary valve 6; a water supply valve 8 attached between the thermal storage tank 3 of the regenerative type night electric boiler (A) and the water supply pipe 2 connected thereto; and a discharge valve 10 attached to the feed pipe 4 of the general boiler (B) connected with a discharge pipe 9 of the regenerative type night electric boiler (A).

[5] Moreover, Korean Utility Model Laid-open No. 1999-034332 discloses a hot water boiler using wood as fuel comprising: a boiler body having a hemi- spherical upper part and a water tank formed in a main wall and an upper portion thereof, the boiler body including a combustion chamber formed inside the boiler body, an inlet formed on a front portion of the combustion chamber, a chimney formed on the upper portion thereof in such a way as to communicate with the combustion chamber, a plurality of water flow pipes formed in an upper portion of the combustion chamber side by side at least in two stories and spaced apart from each other at a predetermined interval in such a way as to communicate with the main wall water tank, shielding plates formed at the inlet side between the water flow pipes of the lower portion in such a way as to form rear holes at the rear portion thereof, a plurality of water flow pipes formed on a lower portion of the combustion chamber side by side and spaced apart from each other at a predetermined interval (about lcm) in such a way as to communicate with the main wall water tank, a drawer type ashtray mounted under the water flow pipes; a storage tank formed on the top of the boiler body, the storage tank including a hot water outlet formed on an upper portion thereof and a water flow pipe mounted on a lower end thereof, the water flow pipe of the storage tank being inserted into the main wall water tank of the boiler body, the storage tank being constructed in such a way that the chimney penetrates the inside of the storage tank and a hot water discharge pipe of the boiler body is inserted to the inside of the storage tank; and a hot water exchanging pipe embedded in the storage tank and having an inlet and an outlet, the hot water exchanging pipe being exposed to the outside of the storage tank, wherein the wood boiler is used jointly with an existing oil boiler through a pipe line.

[6] In addition, Korean Utility Model Laid-open No. 1988-16596 discloses a sectional boiler with an automatic alarm and a water heater for cooking.

[7] Furthermore, Korean Utility Model Application No. 94-10466 discloses a technology for heating a room using an air blower after injecting not water but air, and Korean Utility Model Application No. 82-6717 discloses a boiler, which includes a vapor supply pipe connected with a vapor generator via a corrugated hose, an air supply pipe connected with the vapor supply pipe, a water replenishing tank longitudinally mounted in such a way as to be of the same water level as the vapor generator, and a water supply pipe connected with the vapor supply pipe via the corrugated hose.

[8] Additionally, Korean Utility Model Application No. 89-14868 discloses a technology in which a nickel silver steel material having a super high speed thermal conductivity and an excellent thermal absorption power is embedded in the top of an air pipe and an iron plate is covered on the bottom thereof.

[9] The boilers according to the prior arts are nothing but an apparatus which includes heating devices mounted on the circulating pipe to further heat hot water circulated in the circulating pipe and supply the heated hot water, and hence, do not provide a fuel saving effect.

Disclosure of Invention Technical Problem

[10] Accordingly, the present invention has been made in an effort to solve the above- mentioned problems occurring in the rior arts, and it is an object of the present invention to provide an auxiliary heating device of a boiler, which can reduce an operation period of the boiler working by a predetermined temperature set by a hot water sensor by heating circulated hot water, thereby providing a low fuel consumption.

Technical Solution [11] To achieve the above object, the present invention provides an auxiliary heating device of a boiler, which is additionally mounted at a bypassed portion of a circulating pipe to heat hot water circulated in the circulating pipe so as to reduce an operation period of the boiler working by a predetermined temperature set by a hot water sensor to thereby achieve a low fuel consumption.

Advantageous Effects

[12] As described above, the auxiliary heating device of the boiler according to the present invention can provide the fuel economy by reducing the operation period of the boiler working by the predetermined temperature set through the hot water sensor since it second heats water, which was first heated by a boiler, by the auxiliary heating device, and reduce a fuel consumption of the existing boiler since it is mounted on the circulating pipe of the existing boiler.

Brief Description of the Drawings [13] FIG. 1 is a detailed view of a conventional boiler.

[14] FIG. 2 is a detailed view of a boiler according to a preferred embodiment of the present invention. [15] FIG. 3 is a detailed view of an auxiliary heating device of the boiler according to the present invention [16] FIGS. 4 and 5 are views showing auxiliary heating devices of boilers according to other preferred embodiments of the present invention.

Mode for the Invention [17] A heater used in the present invention employs an electrically heating lamp or an electric heater. [18] In Korea which has no underground resources, a matter of the highest priority is to save energy, and an issue to be solved also in future-oriented industries (as an example,

IT industry) to export knowledge and items is an energy saving type fuel efficiency. [19] Ancestors in Korea obtained a double heating effect by using a brazier fed with charcoal while obtaining a room heating effect by heating the floor of a room in a kitchen during the winter time. [20] The present invention provides an effect that water does not easily get cold if heated water is stored in a thermos, and employs a principle that once boiled water can keep its temperature for a long time period if low calorie or energy of a small quantity is kept. Furthermore, a boiler has been developed using a simple principle to heat a room by a circulating motor.

[21] Various studies to develop boilers have been made, but I am convinced through several studies that if an auxiliary heating device is additionally mounted on the boiler, it can stably keep temperature of boiled water for a long time to thereby endure high oil prices and make people live at home peacefully without getting chilly even in winter.

[23] Experimental Example

[24] The present applicant directly manufactured wood boilers, and installed them in mountain villas and houses all over amusement parks in Gwangyang-si, Jeollanamdo in December 2000.

[25] The present invention is directed to an auxiliary heating device, which is not the concept of the typical boilers, and has been achieved after the present applicant studied heaters of several tens kinds on the model of repeated failures through various conceptions, inventions and experiments.

[26] After the first ignition, water stored in a boiler tank is heated to a temperature ranging from 7O⁰C to 8O⁰C. When the heated water is supplied through a circulating pipe, an auxiliary heating device mounted on a side of the circulating pipe is operated simultaneously, and then, when a proper temperature of 7O⁰C to 8O⁰C is kept, a control switch is operated by an instruction set by a temperature sensor to thereby stop the operation of the boiler since the heated water heated by the auxiliary heating device is kept at a temperature ranging from 7O⁰C to 8O⁰C. Accordingly, there is no fuel consumption.

[27] Since the boiler provides a perfect warm-keeping effect, temperature gradually lowers little by little for a long time.

[28] In consideration that the calorie of the auxiliary heating device can be kept using about fourteen or fifteen candle lights, the auxiliary heating device has been desired to be operated with the minimum fuel consumption. Since heat sources for operating the auxiliary heating device are simple heating lights, heater wires or heated water supply, the present invention provides still lower fuel consumption than typical boilers to thereby provide an economical effect.

[29] While heating and cooling systems of various kinds have been disclosed till now, the present invention provides an auxiliary heating device, which can keep a proper temperature with the heat source of a small quantity using the centrifugal force and the principle of acceleration.

[30] [31] Comparative Example [32] The auxiliary heating device of a boiler according to the present invention was mounted on the existing boiler to heat four rooms, and the following result was obtained.

[33] Comparison of averages of four-months fuel consumptions in winter [34]

[35] As a result of the comparison, it was confirmed that fuel economy of at least 60% could be obtained when the auxiliary heating device was mounted on the boiler. [36] Hereinafter, reference will be now made in detail to the preferred embodiment of the present invention with reference to the attached drawings.

[41] As shown in FIG. 5, the auxiliary heating device of the boiler according to a further preferred embodiment of the present invention has a structure in which the bypassed intermediate portion of the feed pipe extends in the inside of the auxiliary heating device and is arranged in a zigzag manner inside the auxiliary heating device. Moreover, the auxiliary heating device includes a heated water supply pipe 21 mounted on an upper portion of one side thereof to heat the feed pipe arranged therein in a zigzag manner, the heated water supply pipe 21 being connected to a pipe provided from a heated water generator, and a heated water discharge pipe 22 mounted on a lower portion of the other side thereof in such a way as to be symmetric to the heated water supply pipe 21.

[42] The heated water generator may be a separate heating device.

[43] Now, operation states of the auxiliary heating devices according to the embodiments of the present invention will be described.

[44] After the boiler 1 is operated and a boiler tank is heated, when heated water heated to a predetermined temperature by a temperature sensor is supplied to the interior of the room through the circulating pump 2 of the feed pipe, the heated water passes through the interior of the room and is introduced into the boiler tank. While the operation of the boiler is stopped by an instruction of the temperature sensor when temperature exceeds the predetermined temperature through a repeated action of the above process, the boiler is actuated to heat the heated water when temperature is below the predetermined temperature.

[45] In this instance, when the heater 10 of the auxiliary heating device 3-1 shown in FIG.

[46] In case of the auxiliary heating device 3-2 according to another preferred embodiment of the present invention, after the boiler 1 is operated and a boiler tank is heated, when heated water heated to a predetermined temperature by a temperature sensor is supplied to the interior of the room through the circulating pump 2 of the feed pipe, the heated water passes through the interior of the room and is introduced into the boiler tank.
