In addition, the utility model also is provided with temperature and time and shows charactron (20), period adjustment button (21 in the front, 22), relay indicating light (23,24), temperature and time shows charactron (20), period adjustment button (21,22), relay indicating light (23,24) and heat sensor (5, RJG) be connected with the port of microcomputer controller (4) respectively.

The operation principle of the present utility model and the course of work are described in detail in detail below.

Microcomputer controller is controlled boiler at times and be switched on or switched off control circuit and main circuit every day, and working hour can be adjusted according to user's needs, and the user also can select not continuous operation mode at times.Microcomputer controller can also be switched on or switched off the heat-generating pipe power supply automatically according to water temperature.During work; microcomputer controller is at first connected magnetic valve DZ1; heating water tank begins water inlet, and when water level was higher than the excessive low water level protection water level, travel switch XK3 connected; control circuit is connected heat-generating pipe R2 power supply automatically; the water of heating water tank begins heating, and when the water level of heating water tank reaches on the water level in limited time, travel switch XK2 disconnects; magnetic valve DZ1 closes automatically, and heating water tank stops into water.

After the water of heating water tank is opened, temperature controller WK1 cuts off the power supply of heat-generating pipe R2 automatically by A.C. contactor CJ2, heating water tank stops heating, and at this moment the normally closed interlock of A.C. contactor CJ2 resets and connects magnetic valve DZ2, and boiling water enters the water storage incubator from heating water tank.At this moment magnetic valve DZ1 is in closed condition owing to also be subjected to the control of temperature controller WK1, thus when the DZ2 conducting, not conducting of DZ1, thus prevent that unboiled water and boiled water from mixing.When the water level of storage tank surpasses the excessive low water level protection water level; microcomputer controller is switched on or switched off A.C. contactor CJ1 automatically by heat sensor RJZ; thereby the heat-generating pipe of control water storage incubator heats or stops heating, guarantees that the boiling water in the water storage incubator is in constant temperature.When the water level of storage tank reaches in limited time, travel switch XK4 disconnects, and magnetic valve DZ2 closes, and the water storage incubator stops into water.When having water or water level, heating water tank do not reach in limited time, reduction along with temperature in the heating water tank, temperature controller WK1 connects, entering water electromagnetic valve is connected and is begun water inlet, and CJ2 connects simultaneously, and heat-generating pipe R2 begins again to add and heat, when water level rises in limited time, travel switch XK2 disconnects, and magnetic valve DZ1 outage stops into water.

When user's water, the water level of storage tank begins to descend, when at this moment being boiling water as heating water tank, then magnetic valve DZ2 connects by normally closed interlock and the travel switch XK4 of CJ2, when not opening as the water of heating water tank, then the normally closed interlock of DJ2 is an off-state, and magnetic valve DZ2 then can not connect, and guarantees the unboiled water that storage tank does not enter out.

When self-timing when start again behind the boiler timing shutdown, when being lower than 70C as the water temperature in the water storage incubator, temperature controller WK2 connects, and when opening, then magnetic valve DZ3 connects, and emits the interior cold boiling water of water storage incubator automatically as K switch.When being in closed condition as K, magnetic valve DZ3 access failure then can draining.During operate as normal, from heating water tank enter for to be higher than 70 ℃ boiling water, temperature controller WK2 then disconnects magnetic valve DZ3, is not higher than 70 ℃ boiling water so can not discharge.
