Detailed Description
For better understanding of the objects, technical solutions and effects of the present invention, the present invention will be further explained with reference to the accompanying drawings and examples. Meanwhile, the following described examples are only for explaining the present invention, and are not intended to limit the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for controlling a wall-mounted gas stove, which can be implemented in a main control device of the wall-mounted gas stove, and includes:
step S10, sending a fan starting signal to a fan of the gas wall-mounted boiler;
step S20, if the wind pressure switch closing signal is not received in the first time period of the fan operation, the wind pressure fault is judged to occur;
step S50, after the wind pressure fault is judged, if the wind pressure switch closing signal is not received in the second time period of the fan operation, the fan closing signal is sent to the fan;
and step S60, after the wind pressure fault is judged, if a wind pressure switch closing signal is received in a second time period of the fan operation, an ignition process is executed.
Specifically, a fan starting signal is sent to a fan of the gas wall-mounted boiler, so that the fan is started to operate, timing of a first time period of operation of the fan is started, if a wind pressure switch closing signal is not received when the timing of the first time period is ended, a wind pressure fault is determined to occur, and at the moment, the wind pressure fault may be caused slowly due to the starting of the fan or due to other reasons, such as the fault of the wind pressure switch. In order to effectively eliminate the condition that the wind pressure fault is detected due to slow starting of the fan caused by low environmental temperature, after the wind pressure fault is judged to occur, the fan is kept running, the second time period of the running of the fan is started to be timed, when the timing of the second time period is finished, if the wind pressure switch closing signal is not received, the wind pressure fault is determined to be not caused by the slow starting of the fan, and a fan closing signal is sent to the fan to close the fan. And during the second time period, if the wind pressure switch closing signal is received, determining that the wind pressure fault is recovered, and executing an ignition process. In one embodiment, the firing sequence includes sending a firing command to a firing heater of the gas fired wall-hanging stove. The firing command instructs the firing heater to fire.
Wherein, the wind pressure switch closure signal instructs the wind pressure switch to be in the closure state, is produced by the wind pressure switch. The duration of the first time period and the duration of the second time period are preset parameters, and can be set by technicians according to debugging experience. In one embodiment, the first time period is 5 seconds and the second time period is 120 seconds.
According to the control method of the gas wall-mounted boiler, after the fan is controlled to be started, if the wind pressure switch closing signal is not received in the first time period of the operation of the fan, the occurrence of a wind pressure fault is judged. And after the wind pressure fault is judged to occur, keeping the fan to operate in a second time period, and waiting for the fan to gradually start to generate wind pressure. If in the second time quantum, receive the wind pressure switch closure signal, then confirm that the wind pressure trouble arouses because of the fan starts slowly, and the fan has started and reached standard wind pressure this moment, and the wind pressure trouble has been eliminated, carries out the ignition flow, and the gas hanging stove starts by normal ignition. And if the wind pressure switch closing signal is not received in the second time period, determining that the wind pressure fault is not caused by the slow starting of the fan. Therefore, after the second time period is finished, the fan is timely turned off, so that the temperature of the equipment and the pipeline in the furnace body is not close to the outdoor low temperature, the equipment and the pipeline in the furnace body are prevented from being frozen or burst, and the service life of the gas wall-mounted furnace is guaranteed.
In one embodiment, as shown in fig. 2, after the step of sending the fan-off signal to the fan, the method further includes:
step S70, acquiring the starting times of the current fan;
and step S80, if the current fan starting times are less than the preset maximum starting times, returning to the step of sending a fan starting signal to the fan of the gas wall-mounted boiler.
Specifically, after a fan closing signal is sent to the fan to stop the fan from running, the current fan starting times are obtained. And if the current fan starting times are smaller than the preset maximum starting times, jumping back to the step S and restarting the fan. And if the starting times of the current fan are equal to the preset maximum starting times, the fan is not started any more.
The starting times of the current fan are increased once when the fan goes through the process from starting to closing once. In one embodiment, the maximum number of starts is 3. When the fan closing signal is sent for the first time, the current fan starting frequency is 1, 1 is smaller than the maximum starting frequency 3, the step S10 is returned to be executed, and the fan is started for the second time. And if the fan can be turned off in the step S50 after the fan is started for the second time, accumulating the starting times of the current fan by 1 to be 2, wherein the current grading starting time 2 is less than the maximum starting time 3, returning to execute the step S10 again, and starting the fan for the third time. If the fan can be turned off in the step S50 after the fan is turned on for the third time, the number of the starting times of the current fan is accumulated again to be 1 and is changed to be 3, the number of the starting times of the current fan reaches the maximum number of the starting times of 3, the step S10 is not executed again, and the fan is kept in the turning-off state.
According to the control method of the gas wall-hanging stove, the fan is started for multiple times in a circulating mode according to the preset maximum starting times, and steps S10, S20 and S50 are executed. According to the embodiment, after the current starting times of the fan reach the maximum starting times, the fan is stored to be closed, so that the equipment and the pipeline in the furnace body are prevented from being frozen or burst, and the service life of the gas wall-mounted furnace is not influenced. The embodiment further increases the time for increasing the rotating speed of the fan, and can more reliably eliminate the wind pressure fault caused by slow starting of the fan. On the other hand, when having blockked up the comdenstion water in the pipeline between fan to the wind pressure switch, this embodiment opens and close the fan through manifold cycles and can make the comdenstion water get rid of the pipeline to the solution blocks up the wind pressure trouble that the pipeline leads to because of the comdenstion water.
In one embodiment, as shown in fig. 3, after the step of determining that the wind pressure fault occurs if the wind pressure switch closing signal is not received within the first time period of the fan operation, the method further includes:
step S40, sending a fault display command to a display device of the gas wall-mounted boiler; the fault display command instructs the display device to display the fault information.
Specifically, after the wind pressure fault is judged to occur, a fault display command is generated and sent to the display device, so that the display device displays fault information. The failure display command includes failure information. After the fault is judged, fault information is displayed on the display device, so that a user can timely know that the gas wall-mounted boiler has a wind pressure fault, and certain manual repair is convenient to take.
In one embodiment, the method further comprises the steps of:
and step S90, when a reset command is received, clearing the current fan starting times, and returning to the step of sending a fan starting signal to the fan of the gas wall-hanging stove.
Specifically, no matter which step the control method of the gas wall-mounted boiler is executed in, if a reset command is received, the current fan starting frequency is reset, and the step of sending the fan starting signal to the fan of the gas wall-mounted boiler for the first time is returned again. Wherein the reset command may be issued by the user by pressing a key.
