The first hot water pipe 200 ′ made in this way is disposed to be positioned on the above-described burner 110 as shown in FIG. 3 , and the second hot water pipe 200 ″ is disposed on the first hot water pipe 200 ′. By doing so, as combustion is performed in the burner 110, heat exchange can be smoothly performed in the combustion space surrounded by the metal combustion plate 300, which will be described later.

All. metal combustion plate

The metal combustion plate 300, as shown in [Fig. 3], [Fig. 4] and [Fig. 7], wraps around the above-described first hot water pipe 200 ' and second hot water pipe 200 ", the primary combustion space is formed on the frame 100 to make this. In particular, the metal combustion plate 300 surrounds the first hot water pipe 200 ′ and the second hot water pipe 200 ″ while surrounding the above-described burner 110 therein. ) through the primary combustion. And as the combustion gas burned in this way passes through the metal combustion plate 300, secondary combustion can be made.

To this end, the metal combustion plate 300 is, as shown in [Fig. 3], [Fig. 4] and [Fig. 7], above the first hot water pipe 200 ' and the second hot water pipe 200 " It is formed to be wrapped, and primary combustion is made through the burner 110 therein.

Such a metal combustion plate 300 can be manufactured in any shape as long as it can wrap the above-described first hot water pipe 200 ′ and second hot water pipe 200 ″, but most preferably [Fig. 4] and [Fig. It is preferable to manufacture it in the form of a polygonal pyramid as shown in Fig. 7. This can easily create a primary combustion space therein by connecting the metal combustion plate 300 made of an isosceles triangular shape in a polygonal pyramid shape, and two adjacent metals By forming the combustion slit 310 between the combustion plates 300, the primary combustion combustion gas is promoted to be dispersed by the Venturi Effect and forcibly passed through the combustion slit 310, so that the secondary combustion is performed. to make it happen

combustion slit

Combustion slit 310, as shown in [Fig. 3], [Fig. 4] and [Fig. 7], the above-described first hot water pipe 200 ' and second hot water pipe 200 ″ is a metal installed so as to wrap the shape. A slit for safe use by minimizing the amount of carbon monoxide contained in the combustion gas by promoting dispersion while the combustion gas burned in the combustion plate 300 passes through the metal combustion plate 300 to achieve secondary combustion. to be.

In particular, the combustion slit 310 can be manufactured in various ways depending on the overall shape of the metal combustion plate 300 forming the primary combustion space, but as in [Fig. 3], [Fig. 4] and [Fig. 7], When the metal combustion plate 300 is manufactured in the form of a polygonal pyramid, it is preferable to form a long combustion slit 310 on the edges of two adjacent metal combustion plates 300 while forming a polygonal pyramid. This is to make it easy to assemble in the form of a polygonal pyramid using the metal combustion plate 300 made of a plate shape, as well as to allow the combustion slit 310 to be naturally configured by assembling in the shape of a polygonal pyramid. Of course, even if the metal combustion plate 310 is not manufactured in the form of a polygonal pyramid, anyone in the art to which the present invention belongs can easily know that the combustion slit 310 can be arbitrarily manufactured on each metal combustion plate 310 . .

On the other hand, the metal combustion plate 300 according to the present invention made in this way is preferably made of a metal having high thermal conductivity, for example, copper. This allows the metal combustion plate 300 to be easily heated by the heat burned by the burner 110 described above, and the combustion gas primarily combusted through the combustion slit 310 formed in the heated metal combustion plate 300 passes through This is to enable smooth secondary combustion. Of course, the heated metal combustion plate 300 makes it possible to further reduce the amount of carbon monoxide by allowing combustion to occur again as the combustion gas that has been burned first or is burned secondly comes into contact with each other.

la. heat dissipation

The heat dissipation member 400 is a member installed on the frame so as to surround it at a distance from the above-described metal combustion plate 300 by a certain distance, as shown in FIGS. 1 to 4 . This is, by forming a space between the heat dissipation member 400 and the metal combustion plate 300, while passing through the metal combustion plate 300, the combustion gas with almost no carbon monoxide is generated from the heat dissipation member 400 and the secondary combustion. This is to allow a heat dissipation action to be made to the outside of the heat dissipation member 400 while staying between the metal combustion plates 300 .

In a preferred embodiment of the present invention, the heat dissipation member 400 is configured to have a spherical shape, as shown in FIGS. 1 to 4 , and thus the above-described metal combustion plate 300 and heat dissipation member 400 It is preferable to configure so that the combustion gas having little carbon monoxide stays for a long time by secondary combustion that stays in between and the heat dissipation action can be made evenly in all directions.

In addition, in a preferred embodiment of the present invention, the heat dissipation member 400, as shown in [Figs. This allows the combustion gas having little carbon monoxide to be discharged into the room by secondary combustion staying between the above-described metal combustion plate 300 and the heat dissipation member 400, so that it can be continuously combusted through the above-described burner 110. This is to further enhance the heating effect by increasing the indoor temperature by directly blowing out the combustion gas, which has almost no carbon monoxide, into the room.

According to the present invention made as described above, the primary combustion gas in the metal combustion plate penetrates the metal combustion plate through the venturi effect and secondary combustion is made, thereby minimizing the carbon monoxide content and increasing the thermal efficiency while safely using it. In addition, the present invention can be used by connecting the hot water pipe to a hot water tank, a heating water tank, and a boiler used at home or office, and in addition to this, a construction site, a botanical garden, a greenhouse, a livestock farm, and a fish farm, etc. Purpose of use Accordingly, it is possible to secure a sufficient quantity and use it safely.

[ Example 2]

[Embodiment 2], as in [Fig. 8], when forming the combustion slit 310, the surface of the surfaces facing each other is formed to be widened, thereby reducing the area in which the combustion gas contacts the combustion slit 310 surface. By increasing it, the amount of carbon monoxide is reduced to a minimum, making it safer and more convenient to use.

At this time, the combustion slit 310 may be inclined so as to gradually widen outward or inward as in [Fig. Through the vortex, the combustion gases collide with each other to promote combustion, thereby minimizing the amount of carbon monoxide.

[Embodiment 3], as shown in [Fig. 9], the flange 311 is configured to protrude to face each other by protruding the edges of the adjacent combustion slits 310 to the outside. This is to increase the time for the primary combustion gas to pass through the combustion slit 310 longer, thereby further enhancing the secondary combustion effect formed while passing through the combustion slit 310 .

In particular, in a preferred embodiment of the present invention, the flange 311 is formed to protrude outward along the direction in which the combustion gas flows, so that the flow resistance can be minimized when the combustion gas passes through the combustion slit 310 . Thus, it is preferable to configure it to increase combustion efficiency without disturbing the flow.

In addition, in a preferred embodiment of the present invention, the flange 311 is preferably formed gradually wider toward the outside along the direction in which the combustion gas proceeds. This is to allow the combustion gas secondly burned in the combustion slit 310 to be evenly spread in the heat dissipation member to further enhance the heating effect.
