The specific embodiment
Below in conjunction with embodiment the present invention is further specified.
Referring to Fig. 1, the energy-saving and water-saving electric heater comprises main frame, main frame water inlet 2 and main frame delivery port 3; The main frame main body is a tubular heat exchanger 1, its peripheral electromagnetic heating coil 11 of twining; Be connected with flowmeter 4, supercharging circulating pump 5 before the main frame water inlet 2 in turn; Electromagnetic heating coil 11 connects with power supply through heating control apparatus 9, closing relay 8, disconnection relay 6; Flowmeter 4 electrically connects with disconnection relay 6; Supercharging circulating pump 5 electrically connects with time-delay relay 7, delay controller 10 successively; Main frame delivery port 3 is provided with temperature sensor 13, and itself and temperature controller 12, closing relay 8 electrically connect, and electrically connect with heating control apparatus 9.
Main frame delivery port 3 back are connected with mixes water tank 14.Deposit a part (about 3 liters) cold water in advance therein, the hot water in the heat exchanger 1 flows into the back to be mixed with it, in order to avoid the hot water temperature at delivery port 16 places is too high.
Supercharging circulating pump 5 is by closing relay 7 and delay controller 10 controls; Flowmeter 4 is by breaking off relay 6 controls; Vanadium ferrotianium heat exchanger 1 is by electromagnetic heating coil 11 controls, and electromagnetic heating coil 11 is by heating control apparatus 9 controls, and heating control apparatus 9 is by closing relay 8 and break off relay 6 controls; Heating control apparatus 9 is by temperature sensor 13 and temperature controller 12 controls; Delivery port 16 is connected with cold water pipe 18 through check-valves 17.
During the beginning water; Earlier combination tap 19 being opened several seconds closes again; Act on the flow of water inlet 15, act on flowmeter 4 work, the low current of the mobile generation 1-12V through water; Start the relay 6 closed work of breaking off, break off relay 6 and act on time-delay relay 7 and closing relay 8 work; Time-delay relay 7 acts on 5 work of supercharging circulating pump; The circulation of generation hydraulic pressure; Closing relay 8 acts on heating control apparatus 9 work, and heating control apparatus 9 acts on heater coil 11 work, and heater coil 11 acts on 1 work of vanadium ferrotianium heat exchanger; Temperature controller 12 acts on heating control apparatus 9 work, and temperature sensor 13 acts on temperature controller 12 work; Supercharging circulating pump 5 acts on the cold water pressurized toward check valve 17 in the delivery port 16, flows in the cold water pipe 18 (among Fig. 1 shown in the arrow), and because of intercommunication between the cold water pipe, cold water is behind water inlet 15, through heat exchange once more.After reaching the setting working time, start delay controller 10, act on closing relay 7 disconnections and quit work, closing relay 7 disconnections act on supercharging circulating pump 5 and stop pressurization, and water circulation stops; Open combination tap 19 this moment, can flow out hot water.Act on flowmeter 4 after supercharging circulating pump 5 quits work and quit work, act on after flowmeter 4 quits work and break off relay 6, this moment non-transformer, complete machine quits work.
The temperature action that temperature controller 12 sets carries out work in the size of current of heating control apparatus 9, and vanadium ferrotianium heat exchanger 1 is controlled by the size of current of heater coil 11 and carries out work.Adopt electromagnetic heating coil that vanadium ferrotianium heat exchanger is heated, and directly water is not heated, can realize electricity separation, improve security.
Work/the delay time of delay controller 10 is pressed the length setting of hot-water line, per approximately 5 mitron long delays 1 minute.When water temperature was too high, temperature controller 12 acted on closing relay 8 through power-off signal line 20, and heating control apparatus 9 and power supply are broken off.Attaching plug 21 adopts leakage protecting plug, improves security.
