Abstract

PURPOSE: A chimney for a condensing gas boiler is provided to make condense water flow in a boiler by installing the free section of a chimney on a boiler to be bent up and down. CONSTITUTION: A chimney installed on a gas boiler is installed to be vertical to a side wall (260) or inclined inward. A section of a fourth pipe(310) is bent right. Then the condense water generated by the gas exhausted after combustion flows outside along the inner face of the fourth pipe, and is prevented from being leaked outside by installing a pipe(320) for a connector on the section. The condense water is collected according to the smaller diameter of the pipe for a connector than one of the fourth pipe. The condense water is discharged by being flowed backward into a boiler. Thereby, the condense water generated in the exhaustion of the combustion gas is not leaked outside.

First, the gas boiler 100 includes a cabinet 110, a combustion unit 120 installed in the cabinet 110, as illustrated in FIGS. 1 to 3. The main heat exchanger 130 and the hot water supply 140, and the control unit 150 in close proximity to the combustion unit 120.

The combustion unit 120 adjusts the amount of gas supplied by the solenoid valve 122, and the manifold 124 having the Bunsen burner 124a is fixed to the end thereof. On both sides of the burner 124a, an ignition transformer 127 for enabling initial combustion and a flame detector 127a for detecting whether a flame is generated after ignition are installed. A blower 129 is provided below the manifold 124 to supply air for ignition and combustion.

The main heat exchanger 130 causes heat exchange with heat generated from the Bunsen burner 124a while water is transferred into the pipe by the pump 132, and a pipe 126 having a constant diameter is wound and the pipe ( A plurality of heat absorbing plates 126a are vertically provided between the 126. One side of the pipe 126 is provided with an overheat prevention sensor 128 and a temperature detection sensor 128a to maintain a proper level of water temperature.

The hot water supply unit 140 includes a water storage tank 142, a supplemental water valve 144 for blocking or passing water introduced through the water supply line, and the substance contained in the water passing through the supplemental water valve 144. It consists of a filter 146 to remove. The water supply is supplied to the hot water heat exchanger 147 through the hot water flow switch 145 installed before the replenishment water valve 144, and the heating and return water passing through the filter 146 is supplied.

The water supply and heating return water supplied into the hot water heat exchanger 147 is supplied to the hot water and the heating by the three-way valve 148 in the reheated state. The three-way valve 148 may supply hot water filled in the water supply storage tank 142 by heating according to its operating state, and directly use only hot water.

In addition, the communication 200 installed in the boiler 100 uses the elbow 220 at the end of the first pipe 210 and the first pipe 210 connected to the discharge side of the combustion unit 120. The second pipe 230 is connected horizontally and the air supply pipe 240 fixed in the middle of the second pipe 230.

In the gas boiler having such a configuration, the combustion gas discharged after the heat exchange is discharged into the atmosphere through the second pipe 230 connected to the first pipe 210 connected to the combustion unit 120, and the air supply pipe The outside air heated while passing through 240 is used for combustion through the blower 129.

As such, the slope is inclined to the outside during the installation of the communication, so that the condensed water generated by contact between the gas discharged after combustion and the atmosphere is prevented from flowing out to the outside. A connector pipe 320 provided at the end of the three pipe 300 and a fourth pipe 310 having a plurality of suction holes 312 fixed to the connector pipe 320 were provided.

Here, the connector pipe 320 is preferably used in a bellows type freely bent up and down to have a predetermined angle.

In addition, it is more preferable that the connector pipe 320 and the second pipe 230 be freely bent up and down by the bellows wrinkle 320a of the second pipe 230.

As such, the communication installed in the gas boiler is installed so as to be perpendicular to the side wall 260 or inclined inward, and the work is finished by bending the end of the fourth pipe 310 to the right. Thereafter, the condensed water generated by the gas discharged after combustion is moved outward along the inner surface of the fourth pipe 320 and is prevented from leaking to the outside by the connector pipe 320 installed at the end thereof. do.

That is, since the inner diameter of the connector pipe 320 is smaller than the inner diameter of the fourth pipe 310, the condensed water becomes high, and the condensed water flows backwards into the boiler and is discharged.

As a result, the condensate generated in the process of exhausting the combustion gas is not discharged to the outside.

As described above, the present invention has the advantage of preventing the condensate generated during combustion to be discharged to the outside by providing a Java lock connector pipe at the end of the communication installed in the gas boiler to clean the surrounding aesthetics. .
