Summary of the invention
The utility model is exactly a kind of electric heater that provides in order to solve above-mentioned technical deficiency, not only simple in structure, stable performance, and water-saving and electricity-saving, with low cost.
The utility model is to adopt following technical scheme to realize above-mentioned purpose: a kind of electric heater, comprise the electric heater main body, be located at inner bag and control circuit board in the electric heater main body, heating inner bag and the heater that is connected with control circuit board, water inlet pipe that is communicated with inner bag and outlet pipe, outlet pipe and be communicated with water spot, it is characterized in that: on outlet pipe, be provided with thermostatic valve, this thermostatic valve and water inlet pipe are connected with the temperature adjustment water pipe, between with water spot and temperature adjustment water pipe, be connected with the backflow water pipe, this backflow water pipe is provided with water circulating pump, this water circulating pump input is connected with water pipe with the water spot place, output and temperature adjustment cross current, and this water circulating pump is connected with the control circuit board circuit.
As further specifying of such scheme, described recirculated water delivery side of pump is connected with check valve, this check valve by water circulating pump to temperature adjustment water pipe and water inlet pipe conducting.
The delivery port of described thermostatic valve is provided with temperature sensing device between the junction of backflow water pipe and temperature adjustment water pipe, this temperature sensing device is connected with the control circuit board circuit.
Described water inlet pipe is provided with relief valve, and this relief valve is located between water inlet pipe water inlet and the inner bag.
Described temperature adjustment water pipe is connected by triple valve with water inlet pipe.
Described backflow water pipe is connected by triple valve with the temperature adjustment water pipe.
The beneficial effect that the utility model adopts above technical scheme to reach is:
1. the utility model is provided with backflow water pipe and water circulating pump, can before using hot water, will be extracted in the electric heater heating with the cold water in the water spot water pipe rather than bleed off in vain, saved water resource, the place of central water supply such as publilc baths, hotel particularly, electric heater and very long with the pipeline between the water spot, therefore the total amount of cold water is very big, and very big conserve space is arranged.
2. the utility model is provided with thermostatic valve and temperature adjustment water pipe, and the backflow water pipe is direct and the temperature adjustment cross current, the cold water that refluxes can directly enter thermostatic valve and mix water or enter inner bag by water inlet pipe, so need not to establish in addition the cold water that special container holds backflow, this just makes of the present utility model simple and compact for structure, with low cost, and because simple in structure, its fault rate and maintenance cost are all lower.
3. the utility model detects water temperature at the delivery port of thermostatic valve to being provided with temperature sensing device between the junction of backflow water pipe and temperature adjustment water pipe, when the user need use hot water, detect water temperature earlier and determine again whether water circulating pump needs work, when this has just been avoided the no one to use water circulating pump repeat work cause the waste, and the utility model also is provided with the check valve that prevents that cold water from sealing at backflow water pipe and temperature adjustment water pipe junction, and it is more accurate that temperature sensing device is detected.
Description of drawings
Figure 1 shows that structural representation of the present utility model.
Description of reference numerals: 1. electric heater main body, 2. inner bag, 3. electrothermal tube, 4. control circuit board, 5. water inlet pipe, 6. outlet pipe is 7. used water spot, 8. electronic thermostatic valve, 9. temperature adjustment water pipe, 10. backflow water pipe, 11. check valve, 12. water circulating pumps, 13. temperature-sensing probes, 14. relief valves, 15. triple valves.
The specific embodiment
As shown in Figure 1, the utility model discloses a kind of electric heater, comprise electric heater main body 1, be located at inner bag 2 and control circuit board 4 in the electric heater main body 1, heating inner bag 2 and the electrothermal tube 3 that is connected with control circuit board 4, water inlet pipe 5 that is communicated with inner bag 2 and outlet pipe 6, outlet pipe 6 be connected with water spot 7, on outlet pipe 6, be provided with electronic thermostatic valve 8, this electronic thermostatic valve 8 is connected with control circuit board 4 circuit and is connected with temperature adjustment water pipe 9, between with water spot 7 and temperature adjustment water pipe 9, be connected with backflow water pipe 10 formation loops, and should backflow water pipe 10 and water inlet pipe 5 also be communicated with and form the loop, also be provided with check valve 11 and water circulating pump 12 on this backflow water pipe 10, between electronic thermostatic valve 8 delivery port places and water circulating pump 12 and check valve 11, respectively be provided with a temperature-sensing probe 13, these two temperature-sensing probes 13 are connected with control circuit board 4 circuit, also be provided with the control circuit of control water circulating pump 12 on the control circuit board 4, this control circuit board 4 is connected with water circulating pump 12 circuit.The input of water circulating pump 12 and with the cross current at water spot 7 places, the input of output and check valve 11 is communicated with, check valve 11 by water circulating pump 12 to temperature adjustment water pipe 9 and water inlet pipe 5 conductings.Water inlet pipe 5 is provided with relief valve 14, and this relief valve 14 is located between the junction of inner bag 2 and water inlet pipe 5 and temperature adjustment water pipe 9.The junction of the junction of temperature adjustment water pipe 9 and water inlet pipe 5 and backflow water pipe 10 and temperature adjustment water pipe 9 all is provided with triple valve 15.
