And the bathroom mode life hot water mode is only started, namely the controller controls the second channel C of the first three-way valve 5 to be closed, and the first channel B and the third channel D are communicated. The third three-way valve 11 is opened in the fourth, fifth and sixth passages E, F and G. The heating backwater enters the first heat exchanger 14 from the heating backwater pipe 1 and the water pump 2, is split after passing through the water inlet A of the first heat exchanger 14, one path of the heating backwater reaches the second heat exchanger 10 through the second heat exchange pipeline 3 and the bathroom hot water pipe 12, the other path of the heating backwater reaches the first three-way valve 5 through the first heat exchange pipeline 4, is converged with the bathroom hot water pipe 12 through the intermediate pipeline 13, enters the plate heat exchanger together to participate in heat exchange of the bathroom water, and finally flows back to the heating backwater pipe 1 through the bathroom backwater pipe 9. The bathroom water enters the plate heat exchanger from the bathroom water inlet pipe 8 to exchange heat, and flows out from the bathroom water outlet pipe 7 for users to use.
As can be seen from the above description, under the condition that heating is not used, the gas wall-mounted boiler is controlled by the controller, and the first heat exchange pipeline 4 and the second heat exchange pipeline 3 are used as domestic hot water together, so that the resource utilization rate is improved, and the waste is reduced.
The heating mode and the bathroom mode are simultaneously opened, wherein the controller controls the second three-way valve 11 to be completely opened, the third channel D of the first three-way valve 5 is closed, and the first channel B and the second channel C are opened. The heating backwater enters the first heat exchanger 14 from the heating backwater pipe 1 and the water pump 2, is split after passing through the water inlet A of the first heat exchanger 14, and one path of backwater reaches the first three-way valve 5 through the first heat exchange pipeline 4, and then flows out from the heating water outlet to the heating device for heat exchange, and then returns to the water pump 2 from the heating backwater port for circulation, so that the heating system is obtained. The other path of the water enters the plate heat exchanger through the second heat exchange pipeline 3 and flows to the water pump 2 for circulation, the bathroom water enters the plate heat exchanger from the bathroom water inlet A for heat exchange, and finally flows back to the heating return pipe 1 through the bathroom return pipe 9. The bathroom water enters the plate heat exchanger from the bathroom water inlet pipe 8 to exchange heat, and flows out from the bathroom water outlet pipe 7 for users to use.
As is apparent from the above description, the two first heat exchange lines 4 and the second heat exchange line 3 are simultaneously arranged in the first heat exchanger 14, do not intersect each other, and intersect only at the water inlet AA into the first heat exchanger 14. And thus can be classified into a heating system and a bathroom system. The channels of the first three-way valve and the second three-way valve are controlled by the control controller, so that the heating system and the bathroom system work simultaneously. The novel combustion system is not added, and under the condition of not adding a novel circulating system, the novel combustion system is simple in structure and low in cost, and the volume of the whole device is not additionally increased.
As another alternative embodiment, the first three-way valve 5 and the second three-way valve 11 are replaced by a first control valve, a second control valve and a third control valve, which control the on-off respectively.
As a further alternative, the first heat exchange line 4 and the second heat exchange line 3 may be nested lines.
