Description of drawings Fig. 1 is the utility model structure chart.

The specific embodiment

It is to realize by the handle (14) on the three-way diverter valve that is rotationally connected (9), link gear (12), the taps valve (11) that heating of the present utility model and health hot water use.By assembling shown in Figure 1, when the position of handle (14) was in the heating use, three-way diverter valve (9) made the state that water flow switch (8) is in out that is exported to of water circulating pump (22), makes running water inlet be in the state of pass to water flow switch (8).The state that link gear (12) is in out taps valve (11).After connecting power supply, controller (10) makes and adds water solenoid valve (19) unlatching automatically, and running water adds water through adding water solenoid valve (19) automatically to water tank (17), and adds water to radiator.After the water level of water tank (17) adds to desired location, water level switch (18) signal passes to controller (10) and makes and add water solenoid valve (19) automatically and close, stop to add water, and startup water circulating pump (22), water in the heating system by water tank (17) through water circulating pump (22) pressurization enter three-way diverter valve (9), water flow switch (8) enters heat exchanger (4), taps valve (11) is flowed through behind a plurality of radiators, and heating water is got back to water tank (17), constantly circulation.As current when water flow switch (8), sensor on the water flow switch (8) has signal, controller (10) rotates smoke exhaust fan (2), produce the pressure differential signal, blast safety switch (16) arrives controller (10) with sensing, gas valve (13) is opened, and auto-ignition combustion, burner (6) is in duty.At this moment, the water that flows in heat exchanger (4) lining is heated, and constantly circulation in heating system, heating constantly, and each radiator has reached the purpose of heating.The temperature of heating is detected by water temperature probe (7), and the controller (10) by device, the size of control quantity combusted, or start, shut down, reach the design temperature of radiator.In the time will using health hot water, forward handle (14) to position that health hot water uses, the axle on the turning handle (14) makes three-way diverter valve (9) rotate an angle, and water circulating pump (22) is to the pathway closure of water flow switch (8).Running water inlet to the path of water flow switch (8) is opened, and the link gear (12) on handle (14) axle cuts out taps valve (11) simultaneously.Cut off the path of heating water.When turning handle (14), cam on the axle (20) has also rotated an angle, microswitch (21) is opened, and make controller (10) be in the duty that health hot water uses, water circulating pump (22) outage stall, at this moment, open the health hot water switch (25) on the health hot water, running water is entered heat exchanger (4) and is flowed out through health hot water switch (25) and use by flow through three-way diverter valve (9), water flow switch (8) of running water inlet (24).When water flowed out, the sensor on the water flow switch (8) is passed to controller (10) with signal rotated smoke exhaust fan (2), produces the pressure differential signal, blast safety switch (16) arrives controller (10) with sensing, gas valve (13) is opened, and auto-ignition combustion, health hot water produced.
