Description

An apparatus for sensed water high level of a condensate}

The present invention relates to a condensate high water level detection device of a gas boiler that can automatically detect that the condensate is raised above the allowable water level that can be normally discharged through the condensate receiver. The present invention relates to a high-density condensate water level detection device of a gas boiler that detects abnormal condensate from the exhaust gas flowing into the condensate receiver due to cold weather or foreign matters, and enables the boiler to be automatically stopped.

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 air 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 utilizing the latent heat of condensation of the exhaust gas generated at this time. You can.

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 addition, when the condensate tray of the siphon structure is frozen or blocked due to cold weather or foreign matter, condensate from the exhaust gas flowing into the condensate tray rises abnormally to the level of the exhaust duct, and thus the exhaust gas is not discharged normally. Because of incomplete combustion, it was the cause of the generation of harmful gases, which had a problem that the combustion efficiency and safety of the boiler is lowered as a result.

Therefore, the present invention has been made to solve a structural problem that prevents smooth external discharge of the exhaust gas when the condensed water from the exhaust gas of the conventional condensing gas boiler is not normally discharged through the condensate receiver. The combustion efficiency of the boiler by detecting that the condensate from the exhaust gas flowing into the condensate receiver rises abnormally when the condensate tray of the siphon structure is frozen or blocked due to cold weather or foreign matters, so that the boiler operation can be automatically stopped. The purpose is to provide a high water condensate detection device of the gas boiler to increase the.

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 configured to detect the rising water level of the condensate overflowing to the exhaust duct above the discharge allowable level when the condensate receiver of the siphon structure is frozen or blocked, so that the boiler can be automatically stopped. It is characterized in that the high water level sensor is electrically connected to the main controller between the upper and lower discharge allowable water level of the condensate receiver is installed up and down.

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

Figure 1 shows a schematic internal structure of the gas boiler installed in the condensate high water level detecting device of the present invention, Figure 2 shows a detailed structure of the condensate plate installed the condensate water level detection device of the present invention.

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 is normally maintained in the condensate receiver 10 connected between the bottom exhaust duct 22 and the condensate outlet 14.

In addition, the condensate receiver 10 is bent 180 degrees so that the flow direction can be switched while the condensate remaining by a certain level of the condensate receiver 10 connected to the bottom of the exhaust duct 22 below the exhaust portion In the upper portion, when the condensate receiver 10 of the siphon structure is frozen or blocked, the high water level sensor 16a can detect the rising level of the condensate that overflows to the exhaust duct 22 above the discharge allowable water level L. 16b is installed and electrically connected to the main controller.

The high water level sensor connected to the main controller connected to the bottom of the condensate receiver connected to the bottom of the exhaust duct is connected to the main controller, and the inside of the condensate receiver is frozen or clogged due to cold weather or foreign matter. The condensate level is automatically sensed before the condensate rises abnormally and overflows the exhaust duct.At the same time, the detection signal can be transmitted to the electrically connected main controller. In such cases, the boiler should be automatically stopped.

In addition, the discharge allowable water level (L) corresponds to the maximum residual water level of the condensate filled in the intermediate portion of the condensate receiver not passed through the condensate remaining in the condensate receiver exhaust gas is not condensed.

In this way, the condensate can remain at a certain level, and automatically detects the condensate that rises abnormally through the water level sensor 16a (16b) installed on the upper side of the condensate receiver connected to the exhaust duct above the allowable discharge level of the condensate receiver. According to the present invention, the condensate receiver 10 of the siphon structure is frozen or blocked due to cold weather or foreign matter, and condensed water from the exhaust gas flowing into the condensate receiver 10 of the condensate receiver 10. It does not flow into the room through the condensate outlet 14 through the open space, and detects this before overflowing to the exhaust duct 22 above the upper portion of the condensate receiver 10 so that the operation of the boiler can be automatically stopped.

That is, when the condensate receiver 10 of the boiler is not freed or clogged, the condensate from the exhaust gas condensed while passing through the main heat exchanger 26 is not normally discharged below the allowable discharge level L of the condensate receiver 10. As the condensate flowing into the condensate receiver 10 overflows to the upper side of the exhaust duct 22 above the discharge allowable water level L, the water level rises to the exhaust gas discharge space of the exhaust unit 20 and proceeds to incomplete combustion of the boiler. Before the operation, the high water level of the condensate overflowed abnormally by the high water level sensor 16a, 16b installed on the upper part of the condensate receiver 10 can detect the elevated high water level and automatically stop the operation of the boiler. It is possible to structurally prevent the generation of harmful gases.

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 high water level detecting device of the gas boiler according to the present invention, when the condensate receiver of the siphon structure is frozen or blocked due to cold weather or foreign matter, condensate from the exhaust gas flowing into the condensate receiver is exhausted. By detecting abnormally rising water level on the duct, the boiler can be automatically stopped to provide the effect of structurally preventing the generation of harmful gases due to incomplete combustion, thereby doubling the stability of the boiler.
