Method as described above, when restarting the wall-hung boiler of emptied of water, dry combustion method in order to prevent, need first to wall-hung boiler into
Row moisturizing, when wall-hung boiler needs to restart at low ambient temperatures, the residual moisture in hydraulic pressure sensor can be in low temperature environment
Lower icing, due to hydraulic pressure sensor ice blockage, water pressure sensing film contact causes hydraulic pressure sensor that cannot detect less than water flow
Water flowing pressure (detecting that hydraulic pressure is zero) in pipe, at this point, above-mentioned method is only needed in wall-hung boiler by setting hydraulic pressure switch
Hydraulic pressure moisturizing to when reaching preset starting hydraulic pressure value, hydraulic pressure switch can be touched, the hydraulic pressure switch is anti-to controller
Enabling signal is presented, the controller controls the wall-hung boiler starting after receiving the enabling signal that hydraulic pressure switch is fed back.
After the wall-hung boiler starting, the water flow in wall-hung boiler is heated, the icing being heated in hydraulic pressure sensor
Melt, the water pressure sensing diaphragm of hydraulic pressure sensor is allow to touch water flow again, in hydraulic pressure sensor real-time detection wall-hung boiler
Hydraulic pressure and feed back the hydraulic pressure information that detects to controller.
The controller receives the hydraulic pressure information of hydraulic pressure sensor feedback and controls the wall-hung boiler moisturizing to wall-hung boiler
Interior hydraulic pressure reaches the preset operation hydraulic pressure value of the wall-hung boiler, and the wall-hung boiler is made to enter normal operating condition, the wall
It hangs the preset operation hydraulic pressure value of furnace and is not less than the preset starting hydraulic pressure value of the wall-hung boiler.
Specific embodiment two:
Shown in referring to Fig.1, present embodiment discloses a kind of wall-hung boiler, including wall hanging furnace body 1, controller, the wall hangings
It is connected on furnace body 1 into water water route 2, water outlet water route 3, the water inlet water route 2, the connection of water outlet water route 3 constitute circulation waterway, institute
Controller is stated on wall hanging furnace body 1, is run for controlling wall hanging furnace body 1, further includes hydraulic pressure switch 4, the water outlet
Water route 3 is equipped with branch 31, and the hydraulic pressure switch 4 is set on branch 31, and the hydraulic pressure switch 4 is electrically connected with the controller, and uses
In when the hydraulic pressure in circulation waterway reaches preset starting hydraulic pressure value to controller feed back enabling signal.
The wall-hung boiler further includes hydraulic pressure sensor, and the hydraulic pressure sensor is set on the water route in the wall-hung boiler,
The hydraulic pressure sensor is electrically connected with the controller, and feeds back hydraulic pressure for the hydraulic pressure in wall-hung boiler described in real-time detection and to controller
Information.
The wall hanging furnace body 1 includes bracket 11, heat exchanger 12, burner 13, and the heat exchanger 12, burner 13 are in
Arrangement is set on bracket 11 up and down, and the wall-hung boiler further includes air inlet pipeline 5, the air inlet pipeline 5 and 13 phase of burner

To the preset starting hydraulic pressure value of wall-hung boiler, while it being also used for the on-off in control water outlet water route 3, it, can be with before wall-hung boiler starting
So that local water route is in closed state in wall-hung boiler, when moisturizing, can be with the hydraulic pressure in the fast lifting part water route, so that water
It compresses switch and 4 is touched faster, start the wall-hung boiler faster.
Due to rear, hydraulic pressure switch 4 is connected, although the hydraulic pressure in circulation waterway reduces, is driving for the wall-hung boiler starting
Motivation structure drives down, and water flow flows in circulation waterway, and is exchanged heat by heat exchanger 12 so that in circulation waterway water flow temperature
It is gradually increasing, when water flow temperature rises and melts the icing of hydraulic pressure sensor in circulation waterway, hydraulic pressure sensor is to controller
Hydraulic pressure information in feedback cycle water route, controller controls water compensation mechanism water inlet moisturizing, until the hydraulic pressure in circulation waterway reaches
The preset operation hydraulic pressure value of wall-hung boiler, wall-hung boiler enter normal operating condition.
By the above-mentioned description of this invention it is found that compared with prior art, a kind of wall preventing wrong report water shortage of the invention
Furnace control method and wall-hung boiler are hung, by the way that hydraulic pressure switch is arranged, when the hydraulic pressure in wall-hung boiler reaches preset starting hydraulic pressure value,
Hydraulic pressure switch feeds back enabling signal to controller, to make controller control wall-hung boiler starting, avoids due to hydraulic pressure sensor knot
Ice blocking, water pressure sensing film contact cause control mainboard to be mistakenly considered water shortage in wall-hung boiler and trigger water shortage failure less than water flow
Alarm, also result in the generation that wall-hung boiler can not normally start, improve the usage experience satisfaction of user.
