Description

Self-diagnosis device of boiler at long time stop

When the boiler is stopped for a long time, the microprocessor is used to check each part, for example, on a daily basis, and to inform the user of the abnormal part by indication lamp or the promised method. It relates to a self-diagnosis device of the boiler at stop.

Normally, home boilers are heating devices that keep our living culture pleasant in winter or summer. Such boilers take valuable life and property by explosion and gas leaks, but improve product quality or use. Due to fuel changes, accidents due to boilers are gradually decreasing.

In other words, in order to eradicate even minor safety accidents, boilers have mechanical safety devices such as combustion safety devices, overheat protection devices, and low water level blocking devices to prevent safety accidents such as explosions during abnormal operation.

By the way, the boiler currently used only checks the status of each part and function of the boiler only during operation to operate the safety device in case of any abnormality, stops the boiler and turns on the inspection lamp to inform the user of the abnormality.

However, the above check function is operated only when the boiler is in operation, so if the boiler is operated to use hot water or to heat for a short time during spring, summer and autumn or the rainy season, the boiler will not operate continuously. It was often impossible to find the presence of this, so it was often impossible to operate the boiler when absolutely necessary.

The present invention has been devised to solve the above problems, and even when the boiler is stopped for a long time, the microprocessor automatically checks each part with a certain period and checks the status regardless of the boiler's operation. The purpose of the present invention is to provide a self-diagnosis device for a boiler that can be used more safely and conveniently by informing the user by a display lamp or a promised method to take further action.

In order to achieve the above object, the self-diagnosis apparatus of the boiler at a long time stop of the present invention includes a blower output unit 7 and an RPM inspection unit 4 for checking whether there is an abnormality of the blower in the microprocessor 1 of the controller. Pump output unit 8 and flow switch 6 for checking whether there is an abnormality, wind pressure switch 10 are installed respectively, and temperature sensor output unit 9 and flame detection for disconnection and abnormality detection of the temperature sensor. Flame inspection unit (5) for checking the abnormality of the sensor, disconnection and short circuit of the low water level sensor, water level inspection unit (2) for checking the low water level, gas detection input unit (3) and freeze inspection unit (11) for always inspection at stop Each of them is installed.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing the self-diagnosis apparatus of the boiler when the prolonged stop according to the present invention, the self-diagnostic apparatus of the prolonged stop of the present invention, unlike the conventional one, even if the boiler is stopped for a long time, the microprocessor (1) For example, each part, such as a blower, a pump, a wind pressure switch 10, a flow switch 6, and a temperature, a low water level, and a flame detection sensor are checked at a daily cycle, and thus not shown indicator lamps or promises. By using a method (for example, an alarm sound) to inform the user of the abnormal part, safety measures can be taken early to ensure safer driving.

That is, the microprocessor (1) of the controller is connected to the input and output values of the respective parts as described above, so that not only during the long-term stop even after using in winter, each part is not always checked during operation, Each part can be inspected on a daily basis (adjustable time).

As shown in FIG. 2, when the microprocessor 1 takes over the blower and the wind pressure switch 10 of the parts, an abnormal part is generated, that is, the blower is operated and the blower output part 7 and the RPM inspection part 4 are removed. In case of abnormality in blower by measuring RPM, the relevant safety device can be operated to take safety measures and inform the user by not shown indicator lamp or promised method (e.g. alarm sound).

In addition, when the blower is normally operated and the wind pressure switch 10 is abnormal, the blower output unit 7 and the wind pressure switch 10 are inspected by the microprocessor 1 to operate the corresponding safety device to take safety measures. Unsuccessful indication lamps or scheduled alarms can alert the user visually.

On the other hand, in a state in which the blower and the wind pressure switch 10 of the boiler are normally operated, the microprocessor 1 operates the pump and checks the flow switch 6 by using the pump output unit 8 and the flow switch 6. do. At this time, if the abnormality of the flow switch (6) is confirmed through the pump output unit 8 in the microprocessor (1), the safety device is operated to take safety measures, and the user is visually visualized with an indication lamp or a promised alarm not shown. Can be informed.

Subsequently, in the state in which the blower, the wind pressure switch 10, and the flow switch 6 of the boiler are normally operated, the microprocessor 1 may check an abnormality of the temperature sensor, the low water level sensor, and the flame detection sensor.

In the microprocessor 1, the temperature sensor output unit 9 compares the measured value of the temperature sensor to check for disconnection and abnormality of the temperature sensor, and the flame detection unit 5 measures the measured value of the flame sensor. In comparison, it is possible to check whether there is an abnormality of the flame detection sensor, and check the low water level sensor through the water level inspection unit 2 to check the disconnection and short circuit of the low water level sensor and the low water level state.

Therefore, when an abnormality occurs in the temperature sensor, the low water level sensor and the flame detection sensor in the microprocessor (1), the user can immediately follow the instructions by indicating the indication lamp or a promised method so that the boiler can be used more safely and conveniently. Can be.

In the gas detection, the microprocessor 1 is always inspected at the time of stopping through the gas sensing input unit 3, and the freezing wave inspection unit 11 is installed in the microprocessor 1 in order to prevent freezing of pipes in winter.

As described above, according to the present invention, even when the boiler is stopped for a long time, the microprocessor automatically checks each part with a certain period and checks the status regardless of the operation of the boiler. It can provide self-diagnosis device of boiler at long time stop which can make the boiler safer and more convenient.
