Abstract
The utility model provides a novel electromagnetic inducing heating device comprising a controller, a coil tube and induction coils. The controller is connected with the induction coils wrapping the coil tube. The novel electromagnetic inducing heating device further comprises a temperature sensor arranged at the center of the induction coils, and the temperature sensor is mutually connected with the controller. Due to the fact that the temperature sensor is connected with the induction coils, the temperature sensor can acquire the temperature of the induction coils and is connected with the controller; when the induction coils are too high in temperature, the controller can control power of the induction coils to keep the same in the constant temperature, whereas when the induction coils are too low in the temperature, the controller can control the induction coils to keep the temperature of the same in a stable state.
Description
Technical field
The utility model relates to a kind of electromagnetic induction heater, especially relates to a kind of temperature controlled electromagnetic induction heater.
Background technology
Electromagnetic induction is to produce alternating magnetic field by the electronic circuit board part, placing superincumbent container table mask namely cuts the alternation magnetic line of force and partly produces eddy current at the container bottom metal, eddy current makes the iron molecule high speed random motion of container bottom, and molecule collides mutually, rubs and produces heat energy.Thereby play the effect of heating article.Present electromagnetic oven, electromagnetic stove all adopt electromagnetic heating technique.
Existing electromagnetic heater does not carry out monitoring temperature, causes like this that coil is overheated in some cases, makes thermal losses increase, and causes energy waste, and is serious, also can produce potential safety hazard.
The utility model content
For solving the technical problem that above-mentioned electromagnetic heater does not possess temperature control function, the utility model provides a kind of novel electromagnetic induction heater, comprise controller, coil tube and induction coil, described controller is connected with induction coil, described induction coil is wound on the coil tube, also comprise temperature sensor, described temperature sensor is arranged at the centre of described induction coil, and described temperature sensor is connected with described controller.
Described temperature sensor is infrared sensor.
Wherein, described coil tube is the metallic conduit structure.
Wherein, described coil tube arranges at least one air channel outward, and described air channel is provided with blower fan, and described blower fan is connected with controller.
Wherein, described induction coil is attached on the base plate of coil tube after twining or coil into the line cake of rule.
Wherein, described controller comprises four groups of drive circuits.
Wherein, between coil tube and the induction coil, also be provided with the insulation layer.
Adopt this technical scheme, owing to adopt temperature sensor to be connected with induction coil, temperature sensor can obtain the temperature of induction coil, and is connected with controller, when the coiler part temperature is too high, the controller part can be controlled the power of induction coil, make it temperature constant, otherwise, when temperature low excessively, the controller part also can be controlled induction coil, makes coil temperature maintain a stable status.
Description of drawings
The structure chart of the novel electromagnetic induction heater that accompanying drawing 1 provides for the utility model;
The circuit diagram of the drive current that accompanying drawing 2 provides for the utility model.
Description of drawings:
1. controller 2. induction coils 3. coil tubes 4. temperature sensors
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
See also Fig. 1, present embodiment provides a kind of electromagnet heater, comprise controller 1, coil tube 3 and induction coil 2, described controller 1 is connected with induction coil 2, and described induction coil 2 is wound on the coil tube 3, induction coil 2 is attached on the base plate of coil tube 3 after twining or coil into the line cake of rule, between coil tube 3 and the induction coil 2, also be provided with the insulation layer, like this, induction coil 2 forms one or more warm areas, is convenient to heatable substance is realized accurately control.Also be provided with and comprise temperature sensor 4, described temperature sensor 4 is arranged at the centre of described induction coil 2, and described temperature sensor 4 is connected with described controller 1.
Described coil tube 3 is the metallic conduit structure, coil tube 3 is provided with at least one air channel, described air channel is provided with blower fan, described blower fan is connected with controller 1, the air channel is provided with the blower fan of specialty customization, also as required load is lowered the temperature rapidly like this, can suppress temperature and rise violently, reach the stable of temperature, also can avoid misoperation.
Concrete, described temperature sensor 4 is infrared sensor.
In addition, as shown in Figure 2, described controller 1 comprises four groups of drive circuits, can realize like this effects such as loss minimum, place of safety be big further improving the product operating efficiency.
The electromagnet heater that the utility model provides, its heating power supply adopts the input mode of three-phase four phase formulas, the core is made up of powerful IGBT full-bridge circuit, concrete, power supply is behind over commutation, carry out inactivity compensation and harmonic wave processing by reactor, improved power factor (PF), reduced reactive power greatly.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
