Description
Technical field
The utility model relates to a kind of small household appliances, particularly relates to a kind of electromagnetic heater.
Background technology
Electromagnetic oven has another name called electromagnetic stove, is the product of modern kitchen revolution, and it allows heat directly produce in the bottom of a pan without the need to naked light or conduction-type heating, and therefore the thermal efficiency is greatly improved.Be a kind of energy-efficient kitchen tools, be different from all the having fire or heat kitchen tools without fire conduction of tradition completely.Electromagnetic oven is the electric cooking apparatus utilizing electromagnetic inductive heating principle to make.Be made up of parts such as high-frequency induction heating coil (i.e. magnet exciting coil), RF power conversion equipment, controller and ferromagnetic material the bottom of a pan cookers.
The principle of electromagnetic oven utilizes alternating current to produce direction changing alternating magnetic field by coil, and the inside being in the conductor in alternating magnetic field will there will be vortex current, and this is in eddy electric field promotion conductor caused by carrier moving; The joule heating effect of vortex current makes conductor heat up, thus realizes heating.
But the heating of electromagnetic oven must rely on pot, the material of pot is necessary for irony or steel alloy, strengthens magnetic strength with its high magnetic permeability, thus greatly strengthens eddy electric field and eddy current thermal power.And utilizing iron pan to heat, the more difficult control of number ratio of its heating objects, for only needing the occasion heating a small amount of article, can cause the waste of the energy.In addition, the temperature control of existing electromagnetic oven to heating object neither be very convenient.
Summary of the invention
The utility model object is to provide one can accurately control to heat quantity for the defect of existing electromagnetic oven, and temperature controls electromagnetic heater easily.
The utility model for achieving the above object, adopts following technical scheme:
A kind of electromagnetic heater, for the material in heating container, comprises electromagnetic oven body, it is characterized in that: it also comprises the heat block of the electromagnetic susceptibility material be placed in container.
It is further characterized in that: described heat block is thin rounded flakes, thin rounded flakes is provided with heat insulation handle.
Described heat block is provided with temperature sensor.
Described electromagnetic oven body is provided with wireless receiving module and temperature display module, described temperature sensor has wireless transmitter module; Described temperature sensor and electromagnetic oven body wireless connections, the temperature display module of described electromagnetic oven body, for showing the temperature of heat block.
Above-mentioned wireless receiving module and wireless transmitter module are bluetooth module.
Further: described electromagnetic oven body is provided with attemperating unit, the power output of electromagnetic oven body is controlled according to the temperature of described heat block.
Preferred: described attemperating unit is PID controller, the power output of electromagnetic oven body is controlled by PID control method.
The heat block that the utility model can generate heat is placed in container, can adjust the quantity of the heatable substance in container easily, decrease the waste of the energy.Be connected with the attemperating unit on electromagnetic oven body by the temperature sensor on heat block, the temperature of heatable substance can be reacted intuitively, and heating-up temperature is controlled.Controlled by the power output of PID control method to electromagnetic oven body, ensure that the speed of heating process, also can reach the object of accurate control temperature simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
An electromagnetic heater as shown in Figure 1, for the material in heating container 5, comprises electromagnetic oven body 1, and is placed on the thin rounded flakes heat block 2 of the electromagnetic susceptibility material in container 5.Thin rounded flakes is provided with heat insulation handle 3.Heat block 2 is provided with temperature sensor 4.Electromagnetic oven body 1 is provided with wireless receiving module and temperature display module 6, described temperature sensor 4 has wireless transmitter module; Described temperature sensor 4 and electromagnetic oven body 1 wireless connections, the temperature display module 6 of described electromagnetic oven body, for showing the temperature of heat block 2.Above-mentioned wireless receiving module and wireless transmitter module can adopt the multiple close range wireless communication pattern such as bluetooth, zigbee.
Described electromagnetic oven body 1 is provided with attemperating unit 7, controls the power output of electromagnetic oven body 1 according to the temperature of described heat block 2.
Preferred: described attemperating unit 7 is PID controller, the power output of electromagnetic oven body 1 is controlled by PID control method.
When the utility model uses, first container 5 is placed on electromagnetic oven body 1, by heat insulation handle 3, heat block 2 is put into container 5, then put into the material needing heating as required.For liquid, also can adopt and first pour liquid into container 5, then put into the mode of heat block 2.The temperature heated as required, the control temperature of the attemperating unit 7 on adjustment electromagnetic oven body 1.Electromagnetic oven body 1 is started working, solenoid produces the changing alternating magnetic field in direction, the inside being in the heat block 2 in alternating magnetic field will there will be vortex current, and the joule heating effect of vortex current makes heat block 2 heat up, thus realize the heating to material in container 5.By the temperature wireless of heatable substance, the temperature display module 6 sent on electromagnetic oven body 1 shows temperature sensor 4 on heat block 2, attemperating unit 7 on electromagnetic oven body 1, according to the difference between the temperature of heatable substance and design temperature, controls the power output of electromagnetic oven body 1.When the temperature difference is larger, the power output of electromagnetic oven body 1 is comparatively large, and firing rate is very fast.When the temperature of heatable substance is close to design temperature, the power output of electromagnetic oven body 1 is less, and firing rate slows down.Thus realize the effect of Fast Heating and accurate temperature control.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
