The present invention relates to a method and apparatus for controlling a waiting time for commissioning a closed boiler. More particularly, when power is supplied to the boiler during initial installation of the boiler, the boiler automatically performs a commissioning operation, thereby causing an abnormality of the boiler. Quickly check whether the boiler has an abnormality, so that the replacement and repair of the boiler is easy, and if there is no water stored in the water tank of the boiler, after waiting for a trial operation for a certain time, water replenishment is made By automatically restarting the ground test run, it is to improve the convenience of operation and boiler use according to the water replenishment.

In general, a boiler refers to a facility that boils water to supply hot water to a heating facility. In the case of a residential boiler, hot water is supplied to a pipe installed on the floor of a room to heat or supply hot water through a water pipe. It is being used.

Such boilers are classified into open type (atmospheric open type) installed in the downward pipe and closed type (atmosphere blocking type) installed in the upstream pipe, and the new boiler is installed due to the aging of the boiler which is being used for the first time during the construction of the house. If this happens, a trial run is performed to check the operating status of the installed boiler.

However, in the trial operation of the boiler as described above, the boiler is inconvenient to be commissioned only after the installer completes the installation of the boiler by pressing a switch for operating the trial operation mode.

In particular, in the case of the hermetic boiler, since a constant pressure must be maintained due to the characteristics of the upstream pipe, when sufficient water cannot be stored in the water tank, even if the installer starts the test operation by pressing the test switch, the water pressure is low. This is stopped, and after that, the water tank is inconvenient to press the start-up switch again after water replenishment.

In addition, if it is impossible to execute the trial run mode due to a mistake of the installer, the user may not check whether the boiler is abnormal, and if an abnormality occurs after the installation of the boiler, the after-service should be applied for repair of the boiler. There is an inconvenience, there was a problem that can not use the boiler until the repair of the boiler is completed.

Therefore, an object of the present invention is to solve the above conventional problems, when power is applied to the boiler during the initial installation of the boiler, the boiler performs a commissioning operation automatically, there is no water stored in the water tank In this case, after waiting for a trial operation for a predetermined time, when the water supplement is made to provide a method and apparatus for controlling the trial run waiting time of the closed-type boiler to restart the trial run.

Another object of the present invention is to provide a method and apparatus for controlling a test run waiting time of a hermetic boiler to improve convenience in use and to improve commerciality.

In accordance with one aspect of the present invention, a method for controlling a waiting time for commissioning a closed boiler according to the present invention includes selecting a commissioning operation of a hot water mode or a heating mode when power is applied, and connecting a system unit corresponding to the selected mode. And controlling whether to input the detection signal transmitted from the low water level sensor, and if there is an input of the detection signal from the low water level sensor, executing a test operation corresponding to the selected mode; If there is no input of the detection signal from the low water level sensor, waiting for a trial operation during the test operation waiting time; and before the test operation waiting time elapses, if a detection signal is input from the low water level sensor, the sensor corresponds to the selected mode. Performing a trial run and inputting a detection signal from the low water level sensor; If not, it characterized by comprising terminating the start-up duration.

In addition, the trial run waiting time control apparatus of the hermetic boiler according to the present invention for achieving the above object, including a power supply for supplying electrical energy for the operation of the boiler, and a water level sensor for detecting the low water level of the water tank And a sensing unit for detecting a temperature of the heating water and whether the heating water is heated, an operation input unit for receiving the operation of the boiler by a user, a control algorithm such as a test operation mode of the boiler, a general operation mode, and the like. A storage unit for storing setting information such as heating water temperature set by a user, and analyzing the signals input to the power supply unit, the sensing unit, and the operation input unit, and storing the setting information input to the operation input unit in the storage unit.

It is done.

Therefore, when power is applied to the boiler, the boiler automatically performs a commissioning operation, it is possible to quickly check whether the boiler abnormality, and to have a constant waiting time when replenishing water, the operation according to the water replenishment and the boiler It is possible to improve the ease of use.

In addition, the ease of use is improved, and the merchandise is more improved.

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

1 is a flowchart illustrating a method for controlling a waiting time for commissioning a closed boiler according to the present invention. After the boiler is installed, when power is applied to the boiler, one of the hot water mode and the heating mode may be selected (S101). do.

At this time, the selection of the trial run of the hot water mode or the heating mode may be automatically selected by the control device of the boiler or may be selected by the user.

In addition, the entry condition to the test run mode, in order to operate only at the first installation of the boiler, when the detection signal is not input for a predetermined time from the low water level sensor installed in the water tank (when water is stored in the water tank) , To determine restart due to a power failure).

When the selected mode, for example, the hot water mode is selected, the three-way valve installed in the boiler is controlled to be connected to the grid for hot water (S102).

Thereafter, it is checked whether the detection signal transmitted from the low water level sensor installed in the water tank is input (S103), and when there is an input of the detection signal from the low water level sensor, that is, the water stored in the water tank is selected. The test operation corresponding to the mode is executed (S104).

If there is no input of the detection signal from the low water level sensor, that is, if there is no water stored in the water tank, the test operation waits for a test operation waiting time (S105), and the test operation waiting time is required by those skilled in the art. Naturally, it can be applied in various ways.

If the detection signal is input from the low water level sensor before the trial operation waiting time elapses, that is, when the user replenishes water in the water tank, a trial operation is performed in the selected mode, that is, the hot water mode (S106). When the detection signal is not input from the low water level sensor, the trial operation is stopped (S107).

When the trial operation according to the selected mode, that is, the hot water mode is completed, the trial operation of the heating mode is selected, and after switching the three-way valve so that the corresponding system part is connected, the process of steps S103 to S107 is repeated (S108). .

As described above, the commissioning mode may be selectively performed by only one of the hot water mode and the heating mode, or the hot water mode and the heating mode may be sequentially performed according to the needs of those skilled in the art.

In addition, when the trial run corresponding to the selected mode is terminated or when the trial run corresponding to the other of the hot water mode or the heating mode is ended, gas gas purge is performed to remove residual air such as piping by the trial run. For example, the residual air in the gas supply pipe can be removed.

Looking at the method for controlling the start-up waiting time of the hermetic boiler as described above in detail, as shown in FIGS. 2A and 2B, when the power is supplied (S201) and the operation mode operation signal is input (S202), the input commissioning mode is input. It is checked whether the operation signal is a hot water system (S203).

If the trial run mode is a trial run mode for hot water supply (S203), the three-way valve is switched to the hot water system unit (S204), and it is checked whether a detection signal is input from the low water level sensor of the water tank (S205).

When the detection signal is not input from the low water level sensor, it is determined that there is no water stored in the water tank, and after stopping the operation of the circulation pump for supplying hot water (S206), replenish water in the water tank ( S207).

In this case, replenishing water in the water tank may be performed by either automatic or manual.

When the water replenishment proceeds as described above, during the first waiting time (S208), whether the detection signal is input from the low water level sensor is continuously checked (S205).

If the detection signal is not input from the low water level sensor so that the first waiting time elapses (S208), it is determined that no water replenishment is made and an error message to inform that the water tank is not supplied. Display (S209).

When the detection signal is input from the low water level sensor (S205), it is determined that a sufficient amount of water is stored in the water tank, the circulation pump is operated (S210) to proceed with the trial operation operation for the hot water system (S211), and When the first trial run time has elapsed (S212), the GAS purge is executed (S213).

Here, the GAS purge (S213) is to remove the air remaining in the gas supply pipe for supplying gas for the combustion operation of the boiler, the GAS purge operation may be variously applied according to the needs of those skilled in the art.

When the GAS purge (S213) is finished, the operation of the circulation pump is stopped (S214), and the switch to the idle mode (S215).

Here, the first commissioning time and the first waiting time can be variously applied according to the needs of those skilled in the art. Since the first waiting time is for the initial water replenishment, the user gives sufficient time to replenish the water directly. Done.

When the input test operation mode is the test operation mode for heating supply (S203), the three-way valve is switched to the heating system (S217), and it is checked whether a detection signal is input from the low water level sensor of the water tank (S218).

When the detection signal is not input from the low water level sensor, the operation of the circulation pump for heating supply is stopped (S219), and then water is replenished to the water tank (S220).

When the water replenishment proceeds as described above, it is continuously checked whether the detection signal is input from the low water level sensor during the second waiting time (S221).

If the detection signal is not input from the low water level sensor so that the second waiting time elapses, it is determined that the water supplementation is not made and an error message is displayed (S222).

When the detection signal is input from the low water level sensor (S218), it is determined that a sufficient amount of water is stored in the water tank, the circulation pump is operated (S223) to proceed with the commissioning operation for the heating system (S224), and When the two-hour operation time has elapsed (S225), the GAS purge is executed (S226).

At this time, by performing only one of the GAS purge operation (S213) during the warm water system commissioning and the GAS purge operation (S226) during the heating system commissioning, it is natural to prevent the waste of fuel due to the redundant GAS purge operation.

When the GAS purge (S226) is finished, the operation of the circulation pump is stopped (S227), and the switch to the idle mode (S228).

Here, the second test run time and the second waiting time may be variously applied according to the needs of those skilled in the art. The second waiting time may not be output by the low water level sensor due to air removal after the first water replenishment. It is preferable to set the shorter time than the first waiting time, but the present invention is not limited thereto.
