Technical Field
The invention relates to the technical field of water supply systems, in particular to a water supply system capable of heating a water pressure sensor and an ignition method of the water supply system.
Background
The wall-mounted boiler is a gas wall-mounted boiler, which is called a gas wall-mounted heating boiler for short and is a water heater using natural gas as energy. The water pressure sensor is tasted and arranged inside the wall-hanging furnace, so that the water pressure inside the wall-hanging furnace is monitored.
To the water pressure sensor of conventional hanging stove, when the user need not use the hanging stove for a period of time (like the condition such as business trip), the user can carry out the drainage operation to the hanging stove, and the water yield in the hanging stove can be discharged completely basically, but still can have a certain amount of ponding in the water pressure sensor, and this part ponding can't be discharged naturally.
In the cold environment in winter, the inside residual moisture of hanging stove pressure sensor freezes, blocks up and gets the pressure mouth, after the unit leads to water to mend the pressure, because pressure sensor gets the pressure mouth and is blocked by freezing, can't detect system water pressure (or detect water pressure and be 0bar), causes the hanging stove to report by mistake the water shortage trouble. At this moment, the wall-mounted furnace cannot be normally started, the normal use of the wall-mounted furnace is seriously influenced, and the user experience satisfaction is reduced.

When the water pressure is lower than a preset threshold value, acquiring the temperature inside the water storage device; then judging whether the temperature is lower than a preset temperature threshold value or not; when the temperature measured by the temperature sensor is higher than 0 ℃, water replenishing operation is carried out on the interior of the water storage device again, and when the temperature is lower than the preset temperature threshold value, the water pressure sensor is heated.
In this embodiment, after a certain water pressure exists in the water storage tank, when the value obtained by the water pressure sensor is lower than a predetermined pressure threshold value, there are generally two situations, the first situation is that the water in the water storage tank is insufficient; the other condition is that the water pressure sensor is frozen and the water pressure cannot be normally monitored. Just so need monitor the temperature this moment, if ambient temperature is less than predetermined temperature threshold value this moment, then just explain the condition of having appeared freezing the jam in the water pressure sensor inside very likely, this moment right water pressure sensor heats, melts the inside ice of water pressure sensor, and water pressure sensor can carry out normal monitoring to water pressure after the ice-cube melts to avoid hanging stove to report by mistake the emergence of the water shortage condition.
In this embodiment, the predetermined temperature threshold is 0 ℃. When the temperature is lower than 0 ℃, the liquid water is frozen.
In this embodiment, water pressure sensor sets up in water storage device's bottom position, can bulge water storage device's diapire even. In this embodiment, the predetermined pressure threshold is the pressure generated when the water inside the water storage device reaches 2/3 of the total volume of the water storage device.
Specifically, a resistance wire is connected to the water pressure sensor, and when the water pressure sensor needs to be heated, the resistance wire is electrified to finish heating action.
In this embodiment, before the water pressure sensor obtains the water pressure inside the water storage device, a step of replenishing water to the water storage device is included.

The purpose of the steps is to ensure that the ice in the water pressure sensor is timely found to be completely melted. When the water pressure is higher than the preset pressure threshold value, the ice cubes are melted in the heating process of the water pressure sensor, at the moment, the water in the water storage device is in contact with the water pressure sensor, the water pressure sensor can work normally, and meanwhile, the water supply system can also perform normal ignition operation or follow-up action.
In the present embodiment, in the step of "heating the water pressure sensor", the heating time is defined to be 60 to 90 seconds. When the time exceeds the above range, if the heating continues, the overheating inside the water pressure sensor is easily generated, causing damage to the devices inside the water pressure sensor. Meanwhile, in the case of the water pressure sensor, after 60 to 90 seconds of heating, the ice cubes inside the water pressure sensor are theoretically dissolved, and then the next heating operation is not needed.
In this embodiment, after the step of "heating the water pressure sensor", when the value measured by the water pressure sensor is lower than the predetermined pressure threshold, the water replenishing operation is performed again inside the water storage device. Because the water pressure sensor is heated, the water pressure sensor is frozen theoretically, if the value monitored by the water pressure sensor is still lower than the preset pressure threshold value, the water quantity in the water storage device is insufficient, and water supplementing operation is needed.
