Description

An apparatus for sensed water level of a condensate

The present invention relates to a condensate level detecting device of a gas boiler capable of automatically detecting the residual water level of condensate that is condensed while the exhaust gas is exchanged by a heat exchanger and falls into the condensate receiver. By detecting the residual water level of the remaining condensate, it automatically stops the boiler operation when the condensate is not detected at a certain level, so that some of the exhaust gas discharged into the atmosphere at high temperature during the combustion operation is introduced into the room through the condensate receiver. The present invention relates to a condensate water level detection device of a gas boiler, which can be prevented by gas.

In general, the gas boiler is divided into a wall-mounted type and a floor-mounted type according to its installation type, and according to the hot water supply method, the heat exchanger of the boiler body supplies hot water by a hot water heat exchanger and stores it in a separate hot water storage tank. When the hot water is supplied, the heating water circulation system is divided into the air circulation circuit in the boiler is blocked from the atmosphere is divided into a closed air-blocking method and an air opening method of the heating circuit in the boiler is open.

The gas boiler is heated by a gas burner in a state in which the heating pipe and the tube are filled with water, and are supplied to the heating pipe and the hot water supply pipe by a circulating pump to heat the room or supply the hot water like a normal hot water boiler. On the other hand, when the temperature of the heated water rises and the pressure inside the boiler rises, an increasing amount of water is supplied to the tank tank through the expansion line, and the heating of the boiler is stopped to decrease the temperature of the water in the pipe and the heating pipe. When the internal pressure of the heating chamber is lowered, water in the cisterns tank flows back into the pipe and the heating pipe through the expansion line due to the pressure difference, thereby forming a circulation structure in which the insufficient water is automatically replenished.

Particularly, in the case of condensing gas boiler, the exhaust gas discharged into the atmosphere at high temperature during combustion passes through the cold part of the heat exchanger to condense below the dew point temperature, thereby improving heating efficiency by using the latent condensation heat generated at this time. .

On the other hand, since the gas boiler is installed near the living room and the living room, the necessity of ventilation is further emphasized according to the characteristics of the fuel and the presence of the room, and in fact, most of the boiler-related accidents are caused by the exhaust gas being introduced into the room. Accidental poisoning due to carbon monoxide (CO) was a major problem.

In particular, in the case of condensing gas boilers, most of the exhaust gas generated by combustion is discharged through the exhaust port when the boiler is commissioned in a state in which there is no residual water level condensate in the condensate receiver. While the condensate of the gas is maintained at a constant level in the condensate tray there is a structural problem that a part of the exhaust gas is introduced into the room through the condensate tray.

Therefore, the present invention was devised to solve all the problems that a part of the exhaust gas flows into the room when the conventional condensing gas boiler is initially commissioned, and the initial level is automatically detected by detecting the residual water level of the condensate remaining in the condensate receiver of the siphon action. Gas boiler that structurally prevents some of the exhaust gas discharged into the atmosphere through the condensate receiver when it is combusted and burned by high temperature when the condensate is not detected at a certain level during the boiler commissioning. Its purpose is to provide a condensate level detection device.

In order to achieve the above object, the present invention can increase the heating efficiency of the boiler by the latent heat of condensation generated by condensing below the dew point temperature by passing the exhaust gas lost to the air at high temperature during combustion to the cold part of the main heat exchanger. A gas boiler having a condensing function, which is configured to be heat-exchanged through the main heat exchanger, in which a portion of the exhaust gas discharged from the outside is prevented from entering the room through the siphon action condensate tray. It is characterized in that the water level sensor is electrically connected to the main controller is installed so that the residual water level of the condensate in the condensate receiver is automatically detected during the initial operation of the boiler.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail as follows.

1 shows a schematic internal structure of a gas boiler in which the condensate water level sensing device of the present invention is installed, and FIG. 2 is a level sensor 16a, 16b according to the present invention installed in the middle of the condensate receiver 10. It shows a detailed structure of the condensate water level detection device.

As shown in the figure, the condensed water of the exhaust gas that is heat-exchanged through the main heat exchanger 26 of the exhaust unit 20 to be condensed below the dew point temperature is discharged outside through the condensation outlet 14 and at the same time, the exhaust unit 20 The condensate receiver 10 is formed in a siphon structure so that a predetermined level of water remains in the condensate receiver 10 connected between the bottom exhaust duct 22 and the condensate outlet 14.

In addition, in the middle portion of the condensate receiver 10 which is bent 180 ° so that the flow direction can be switched while remaining the condensate water by a predetermined level, the water level detection sensors 16a and 16b electrically connected and controlled to the main controller 30 are provided. When the water level of the condensate remaining in the middle portion of the condensate receiver 10 falls below these level detection sensors 16a, 16b so as to be installed above and below at regular intervals to ensure the accurate detection capability of the condensate. Automatically signaled to the main controller 30 is configured to automatically stop the operation of the boiler.

That is, the condensed water condensed while being heat exchanged through the main heat exchanger 26 flows into the condensate receiver 10 having a siphon structure connected to the lower side of the exhaust duct 22 of the exhaust unit 20 and remains at a constant water level to condense water outlet 14. While the discharge flow of the condensate is made to be discharged through the outside, at the same time, the condensate excessively introduced into the condensate receiver 10 is configured to overflow through the overflow pipe (12).

As such, the present invention is configured such that the residual water level of the condensate is automatically detected by the level sensor 16a, 16b installed at the residual water level while the condensed water can remain at a constant level. If the condensed water of the exhaust gas condensed by heat exchange by 26 is not remaining at a predetermined level in the middle portion of the condensate receiver 10 in which the flow direction is changed, the water level sensor 16a, 16b installed at the middle portion detects it. To automatically shut down the boiler.

That is, the condensate receiver 10 before the phenomenon that a part of the exhaust gas flows through the open space of the condensate receiver 10 generated when the residual water level of the condensate water is lower than the reference level during the initial operation or during the operation of the boiler occurs. The residual water level of the condensate is automatically sensed by the water level sensor 16a, 16b installed in the middle of the boiler to automatically stop the operation of the boiler, so that the exhaust gas is discharged before the condensate reaches the constant level. Through the open space of the condensate receiver 10 can be structurally prevented from entering the room via the condensation outlet 14.

Unexplained reference numeral 24 denotes an exhaust port which is an outlet through which the exhaust gas burned is discharged to the outside through the exhaust unit 20.

As described above, according to the condensate water level detection device of the gas boiler according to the present invention, by detecting the residual water level of the condensate remaining in the condensate receiver of the siphon action, the condensate is not detected at the constant water level during the initial operation or during the operation of the boiler. In this case, the operation of the boiler is automatically stopped, and a part of the exhaust gas discharged into the atmosphere at a high temperature during the combustion operation is structurally prevented from entering the room through the condensate receiver, thereby providing an effect of doubling the stability of the boiler.
