Background
When the dual-purpose stove is used for heating in winter, a small part of the time is in a combustion heating state, and most of the time is in a non-combustion state but the water pump is in a running state all the time. When the machine does not burn, the water pump runs so that the water temperature of all places in the floor heating pipeline is relatively uniform, and on the other hand, the water pump can sense the current temperature of the floor heating water in real time for the dual-purpose stove, so that whether heating needs to be started or not is judged conveniently, and therefore the water pump of the dual-purpose stove with a plurality of brands does not stop in the whole heating season.
As shown in figure 1, when the existing dual-purpose furnace is used for floor heating, the water pump 1 'operates, water entering the heating water inlet pipe 3' passes through the combustion heat exchanger 2 'and is discharged to a floor heating pipeline through the heating water outlet pipe 4', and therefore floor heating is achieved. When the domestic warm water is needed, the outlet of the combustion heat exchanger 2 'is not communicated with the heating water outlet pipe 4' by the three-way valve 8 ', the outlet of the combustion heat exchanger 2' is communicated with the plate type heat exchanger 7 ', so that the hot water discharged by the combustion heat exchanger 2' does not enter the heating water outlet pipe 4 ', the hot water discharged by the combustion heat exchanger 2' enters the plate type heat exchanger 7 'for heat exchange, the water in the domestic water inlet pipe 5' enters the plate type heat exchanger 7 'for heating, and then the hot water is discharged to a domestic water pipeline by the domestic water outlet pipe 6'.
Whether the floor heating is used or the domestic hot water is used, the water pump 1 'is always operated, which means that the heating water always circulates through the dual-purpose furnace, and the circulation of the heating water inevitably passes through the combustion heat exchanger 2'. When heating uses at ground heating, the condition of incombustible in having combustion heat exchanger 2 ', reverse heat transfer can certainly appear through combustion heat exchanger 2 ' in the ground heating water of high temperature, exactly during the heat of ground heating water distributes the air through combustion heat exchanger 2 ', hot-air rethread tobacco pipe 9 ' passes through the heat and reaches outdoors, makes the heat of ground heating water scatter and disappear on the one hand like this, and on the other hand combustion heat exchanger 2 ' opens and stops the number of times and can increase, influences the machine life. This heat loss is large particularly in a forced-ventilated type machine having poor sealing performance of the entire machine and a machine installed outdoors.
