The utility model electric heater energy saver both effectively can save electric energy, also can improve the drinking water quality of employee, improve health conditions, and installed and used simple, convenience, and safe and reliable to operation, cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is the circuit block diagram of the utility model electric heater energy saver one embodiment.
Detailed description of the invention
In order to understand the technical solution of the utility model further, by following examples, the utility model is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, the electric heater energy saver of the present embodiment comprises control device, its control device bag main controller 2, output electrical equipment, drive circuit 6, touch display screen 8, temperature detector 9 and corresponding power circuit 10 etc.Temperature detector 9 can for being arranged at the thermal resistance on the hot water barrel of electric heater.
Its main controller 2 comprises microcontroller 3, the temperature detection be connected with microcontroller 3 respectively and comparing unit 5 and timing unit 4.Temperature detector 9 is connected to temperature detection and the comparison circuit 5 of main controller 2, and the input of drive circuit 6 is connected to the corresponding output of the microcontroller 3 of main controller 2.The output of drive circuit 6 is connected to the input of relay switching circuit 7.The output (export and control contact) of relay switching circuit 7 is connected to the heated power power circuit of corresponding electric heater.Power circuit 10 is connected to master controller 2, drive circuit 6 and relay switching circuit 7, and its power circuit 10 provides working power for this control device.
Touch display screen 8 is connected to the microcontroller 3 of main controller 2.Touch display screen 8 is respectively equipped with startup/reset key, temperature setting button and working hour setting button.Touch display screen 8 is provided with the power on/off duty display of the real time temperature display of corresponding electric water heater heating water, the set and display of relevant parameter, running time and electric heater.Setting can be implemented to the temperature of the working hour of electric heater, heating water etc. by touch display screen.
An overload protecting circuit 11 is also comprised in this example; the output of overload protecting circuit 11 is connected to the corresponding input of relay switching circuit 7; the input of overload protecting circuit 11 is connected to corresponding current transformer, and current transformer is located on the power power supply line of electric heater.When overload occurs electric heater, its current transformer exports corresponding signal to overload protecting circuit, disconnects the power supply to electric heater by overload protecting circuit control relay on-off circuit.
Main controller is detected by corresponding timing unit, temperature detection and comparing unit the working hour of electric heater and heating-up temperature, monitors, and implements to control to the operation of electric heater by drive circuit and relay switching circuit.Can automatic control electric water heater by day, during dining, rest period work, and control electric heater dormancy at night or other times.In this example, its drive circuit can be High-power Semiconductor Triode.
Above-described embodiment is only the prominent example of application technical solutions of the utility model, and not detailed description of the invention of the present utility model is exhaustive, and other modified products based on the technical solution of the utility model all belong to protection scope of the present invention.
