Pipe and the Bathroom Live hot water outlet pipe are connected on the main heat exchanger, and the heating loop is connected to the plate-type heat-exchange
On device.
When work: 1) when user has Bathroom Live hot water demand, tap water is straight from the Bathroom Live hot water inlet pipe
It connects and enters in the main heat exchanger, the high-temperature flue gas after fuel gas buring directly heats the cold water in the main heat exchanger, heating
Good Bathroom Live hot water flows through the bath domestic hot-water outlet pipe arrival water spot, second circulation air pump inoperative at this time；2) when
When user has heating demands, second circulation pump startup, the high warm come out from main heat exchanger under the draft of second circulation pump
Water flows to the plate heat exchanger by the heating minor loop, and the first circulation pump startup, recycles heating at the same time
Water is completed heat with Bathroom Live hot water in the plate heat exchanger and is exchanged.
As a further illustration of the above scheme, the plate heat exchanger is raw with the bathroom respectively by two connecting tubes
Work hot water inlet pipe, the Bathroom Live hot water outlet pipe connect and compose heating minor loop.
As a further illustration of the above scheme, on the heating minor loop be equipped be used to will be in the main heat exchanger
Hot water is drawn into the pump of the second circulation in the plate heat exchanger；When user has heating demands, the second circulation pump is opened,
At this time under the draft effect of second circulation pump, the hot water in the main heat exchanger is made to flow to the plate heat exchanger.
It is used to as a further illustration of the above scheme, being equipped in the connecting tube by the Bathroom Live hot water effluent
Hot water in pipe is extracted into the pump of the second circulation in the plate heat exchanger.
It is described board-like to change as a further illustration of the above scheme, the main heat exchanger is mounted in a closed combustion chamber
Hot device is located at outside the closed combustion chamber.
As a further illustration of the above scheme, burner is equipped in the lower section of the main heat exchanger, in the main heat exchange
The top of device is equipped with exhaust fume collecting hood, and blower and balanced type are equipped on the exhaust fume collecting hood to smoke exhaust pipe.
As a further illustration of the above scheme, connecting between the Bathroom Live hot water inlet pipe and the heating loop
It is connected to water supply pipe.
As a further illustration of the above scheme, being equipped with water compensating valve on the water supply pipe.
The beneficial effects of the present invention are:
One, Bathroom Live hot water inlet pipe and Bathroom Live hot water outlet pipe are connected on main heat exchanger, are directly utilized
Main heat exchanger heats bathroom water, reduces the time of bathroom hot water outlet temperature transient changing, to improve users'comfort.
Two, traditional plate is changed formula gas-heating water heater and needs to be commutated using triple valve, and three-way diverter valve frequently switches,
It is easy to appear wear-out failure, to influence the stability of product.The present invention is by newly-increased second circulation pump, by the draft of water pump
The shortcomings that realizing commutation, eliminating three-way diverter valve frequent switching, stable and reliable operation.
