As shown in Figure 1, a kind of supplying hot water instant-heating plate changes formula wall-hung boiler, comprising: wall hanging furnace body 1 is mounted on described
Main heat exchanger 2, combustion system 3, blower 4 on wall hanging furnace body 1, the heating outlet pipe 5 connecting with the main heat exchanger 2 supply
Warm return pipe 6, and for providing the water pump 7 of circulation power；It is characterized in that, series connection is by plate on the heating outlet pipe 5
Formula heat exchanger 8 is connected with bathroom water inlet pipe 9 and sanitary outfall pipe 10 on the plate heat exchanger 8, in the plate heat exchanger
8 heating water outlet is equipped with the first pipe 11 for being used to connect heat dissipation terminal and for directly connecting with the heating water return pipe 6
The second pipe 12 connect, between the first pipe 11, the second pipe 12 and the heating water outlet of the plate heat exchanger 8
Pass through 13 switched conductive of control valve.
Wherein, the control valve 13 is triple valve, and the water inlet pipe of the triple valve and the heating of the plate heat exchanger 8 go out
Water end (W.E.) connection, two outlet pipes of the triple valve 13 are connect with the first pipe 11, the second pipe 12 respectively.At it
In his embodiment, the control valve is to be arranged in the first pipe to be equipped with the first shut-off valve and setting in second pipe
Road is equipped with the second shut-off valve, is not limited to the present embodiment.
The water pump 7 is also set on the pipeline on the pipeline between the main heat exchanger 2 and the second pipe 12
There is water flow sensor 16.The water pump 7, the control valve 13, the water flow sensor 16 are all connect with a controller 14,
The controller 14 is used to control the start and stop of the water pump 7 and the switching action of the control valve 13, and is opened according to the water flow
It closes or the signal of the feedback of water flow sensor 16 controls the igniting starting that the plate changes formula wall-hung boiler.In the present embodiment, preferred institute
Stating controller is the master controller that the plate changes formula wall-hung boiler.In other embodiments, the water flow sensor water flow
Switch in place is not limited to the present embodiment.
