Abstract

The utility model discloses an energy-saving quick electric boiler, which comprises a boiler heating pipe, a rectifier module, a keyboard, a power controller, an IGBT module and a coil. The rectifier module is connected with the IGBT module, the keyboard is connected with the power controller, the output end of the power controller is connected with the control end of the IGBT module, the coil surrounds the outer side of the boiler heating pipe, and two ends of the coil is connected with the output end of the IGBT module. The electric boiler employs high frequency current to heat the water in the heating pipe of the electric boiler, thereby having the advantages of high heat efficiency and low heat energy diffusion loss. Further, the electric boiler saves power utilization time and power utilization quantity, and is small in volume and convenient in installation.

Description

Energy-conservation quick electric boiler

Technical field

The utility model relates to a kind of electric boiler, particularly a kind of energy-conservation quick electric boiler.

Background technology

Existing electric boiler all is electric heating tube to be installed heat and heat up water in boiler, this mode of heating needs good insulation performance, have the lower advantage of cost product cost, but also there is very significant disadvantages in this electric boiler, the one, the efficient of heating is low, and the use cost of product is significantly risen; Heating tube places in the boiler in addition, also easy polluted water.

The utility model content

Add the high technical problem of poor safety performance, energy consumption that water-tube boiler exists in order to solve existing electrothermal tube, the utility model provides the energy-conservation quick electric boiler of a kind of good stability, thermal efficiency height, safety.

The technical scheme that the utility model solves the problems of the technologies described above is: comprise boiler heating tube, rectification module, keyboard, power controller, IGBT module, coil, described rectification module links to each other with the IGBT module, keyboard links to each other with power controller, the output of power controller links to each other with the control end of IGBT module, coil encircling is in the outside of boiler heating tube, the output of its two termination IGBT module.

In the above-mentioned energy-conservation quick electric boiler, also comprise protective relay, relay is serially connected with rectification module and IGBT module, and its control end links to each other with power controller.

Technique effect of the present utility model is: 1) the outer ring coiling of the utility model boiler heating tube, in coil, add high frequency electric again, utilize high frequency electric that the water in the heating tube is heated, this mode of heating thermal efficiency height, heat energy diffusion loss loss is little, saves electricity consumption time and power consumption.2) the utility model has significantly reduced waste, has obvious energy-saving effect, need need how much hot water just heating what, need not store, overcome existing electrothermal tube water heater and stored to too many or too much for use and cause the shortcoming of a large amount of wastes.3) the utility model need not increase capacity with wattage transformer, does not need to transform circuit yet, and volume is little, and is easy for installation.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Fig. 1 is a structured flowchart of the present utility model.

The specific embodiment

Referring to Fig. 1, the utility model comprises rectification module, relay, keyboard, power controller, IGBT module, coil, relay is serially connected with between rectification module and the IGBT module, keyboard links to each other with power controller, the output of power controller links to each other with the control end of IGBT module, coil encircling is in the outside of boiler heating tube, the output of coil two termination IGBT modules.

Operation principle of the present utility model: rectification module is rectified into the input of delivering to the IGBT module behind the dc source with the two-phase or the three-phase alternating current of input, the power controller output control pulse is to the control end of IGBT, use the IGBT module to produce high frequency electric, this high frequency electric flows through high frequency coil heating tube is heated, and makes the very fast heating of cold water in the heating tube.Water temperature is too high or when adding heat anomaly, the power controller control relay disconnects, and guarantees the normal operation of boiler.
