Description
Technical field
The utility model relates to electric heating equipment, particularly a kind of electromagnetic induction heater circuit of doubleway output.
Background technology
Electric heating is the heating system that clean electric energy is converted to a kind of high-quality comfortable environment-protection of heat energy, at present, comparatively general with resistance wire/quartz heating in the Electric heating of electric heating apparatus.But resistance wire/quartz heating, its heat efficiency is very low, and also has the shortcoming of a lot of other sides.This mode of heating, is to be mainly abutted against to touch to conduct transferring heat energy, and the various heating plates made from resistance wire, circle only have a face to touch the position that needs heating, and this has caused again thermal dissipation greatly to suffer at air.Traditional heating collar inside and outside respectively transmits the heat of half theoretically, so we say be dissipated in airborne namely 50%, if certainly the aged words of heater the heat efficiency can be lower so.
Electromagnetic induction heating is that heated object self produces eddy current self-heating, add the cotton insulation effect of insulation, so just overcome heat dissipation in air, power saving rate can reach more than 50% in theory, so but consider that the energy conversion efficiency of controller normally only has 40% left and right.
Electromagnetic induction heating product has the features such as the heat efficiency is high, radiationless, the life-span is long, the electromagnetism wall-hung boiler occurring is in recent years to develop according to the principle of electromagnetic induction heating object, conventionally take water as heated object, utilize electromagnetic induction directly to make water self produce eddy-current heating.
In prior art, electromagnetic induction heater circuit is generally single channel single channel coil, for on the larger heated object of volume (water receptacle), the effect of single channel coil output can not fully be converted into heat energy by magnetic energy on heated object, the efficiency of heating surface is limited to, and there is no at present the electromagnetic induction heater circuit appearance of multichannel output.
Summary of the invention
The purpose of this utility model is exactly the deficiency existing for existing design, and a kind of electromagnetic induction heater circuit of doubleway output is provided
Design, thereby farthest make magnetic energy on heated object, fully be converted into heat energy, reduce thermal losses, reach decline energy consumption, improve the object of heating efficiency.
The utility model is to realize by such technical scheme: a kind of electromagnetic induction heater circuit of doubleway output, it is characterized in that, comprise two electromagnetic control making sheet and two groups of electromagnetic heating coil, the first electromagnetic heating coil and the second electromagnetic heating coil are connected respectively the output of corresponding electromagnetic control making sheet
The first electromagnetic heating coil and the second electromagnetic heating coil are by the coiling of mica insulation wire; The first electromagnetic heating coil and the second electromagnetic heating coil are 4 square millimeters with mica insulation diameter of wire, and it is 29 circles that the first electromagnetic heating coil and the second electromagnetic heating coil are wound around respectively the number of turns on heated object.
Control circuit also comprises temperature controller; Temperature controller circuit comprises single-chip microcomputer, the resistance of the AD port processing thermal resistance by single-chip microcomputer, according to the change in resistance accounting temperature value of thermal resistance, single-chip microcomputer passes through the break-make of I/O control relay coil again, and then by the power supply of two electromagnetic control making sheet of relay contact control.
Electromagnetic induction heater circuit makes the water generates eddy-current heating in heated object hydroecium by the first electromagnetic heating coil and the second electromagnetic heating coil, the circulation waterway during heat is passed to, and realize heating by the heat radiation of radiator group.
The beneficial effects of the utility model are: the electromagnetic induction heater circuit of doubleway output, electromagnetic induction heater circuit comprises two electromagnetic control making sheet and two groups of electromagnetic heating coil, by two groups of electromagnetic heating coil Fast Heating, in heated object hydroecium, form metastable thermal source, by heating loop, form circulating hot water, farthest improve system programming rate, thereby minimizing thermal losses, improves heating efficiency.
