Abstract
The utility model discloses a heating device of electromagnetic stove, which comprises the power supply, electromagnetic coil and power tube which are connected in series and the filter capacitor which is connected in parallel with the power supply. The resonance capacitor is arranged on the electromagnetic coil and connected in parallel to the electromagnetic coil, the control capacitor is arranged inside the heating device and connected with the resonance capacitor, and the control capacitor can either be connected in series or in parallel with the resonance capacitor, wherein if it is the first case the switch will be connected in parallel with the control capacitor, otherwise the switch will be connected in series with the control capacitor. The heating device of the electromagnetic stove with the above structure makes the electromagnetic coil match better to the resonance circuit, thus enabling the electromagnetic stove to maintain continuous heating under different grades of power; therefore the electromagnetic stove is provided with high heating efficiency and low energy consumption, and the heat productivity of the power tube is reduced, which saves the energy.
Description
Technical field
The utility model relates to a kind of electromagnetic oven heating device.
Background technology
At present, the disclosed electromagnetic oven of prior art, electromagnetism drum, power tube that the structure of its heater generally comprises power supply and is connected in series with power supply, the two ends of the power supply filter capacitor that is connected in parallel is provided with the resonant capacitance that is connected in parallel with the electromagnetism drum on the electromagnetism drum.Generally speaking, electromagnetic oven has the mode of operation of multistage power heating usually.The electromagnetic oven of this mode of operation, the resonant capacitance of its heater are single-mode and the configuration of electromagnetism drum, and the general only suitable electromagnetic oven of such configuration is in narrower power section work.When electromagnetic oven need be when other power section be worked, its resonant capacitance and the well co-ordination of electromagnetism drum, electromagnetic heating circuit or the mode of operation of adopt being interrupted heating to be adapting to the job requirement of low-power section, or adopt the continuous heating mode of excess load to adapt to high-power section job requirement.Yet, the heater circuit of this single resonant capacitance and the configuration of electromagnetism drum, its whole efficiency of heating surface is low, and the power tube heating is bigger, causes the waste of the energy to a great extent.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the electromagnetic oven heating device of a kind of efficiency of heating surface height, energy savings is provided.
Goal of the invention of the present utility model is achieved in that a kind of electromagnetic oven heating device, comprise power supply, electromagnetism drum, power tube that is connected in series and the filter capacitor that is connected in parallel with power supply, the electromagnetism drum is provided with the resonant capacitance that is connected in parallel with the electromagnetism drum, it is characterized in that: be provided with the adjustment electric capacity that is connected with resonant capacitance in the described electromagnetic oven heating device.
Described adjustment electric capacity and resonant capacitance are connected in series.
Described adjustment electric capacity and resonant capacitance are connected in parallel.
Be connected in parallel to switch on the described adjustment electric capacity.
Be connected in series with switch on the described adjustment electric capacity.
The utility model improves the electromagnetic oven heating device of prior art, connects one and adjust electric capacity on resonant capacitance, and be provided with switch on adjustment electric capacity.Adjust electric capacity and can be connected with resonant capacitance with the serial or parallel connection pattern respectively and inserts resonant circuit, make the electromagnetism drum harmony circuit that shakes adjust to more excellent association and join, make that electromagnetic oven is equal under power requirements at different levels can realize the continuous preferably operating state that heats with this.Electromagnetic oven heating efficient height, low in energy consumption, simultaneously, also reduced the caloric value of power tube, save the energy.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment 1.
Accompanying drawing 2 is the structural representation of the utility model embodiment 2.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to illustrated in figures 1 and 2, the utility model electromagnetic oven heating device, comprise power supply 1 and the electromagnetism drum 2 that is connected in series with power supply 1, power tube 3, the two ends of power supply 1 filter capacitor 4 that is connected in parallel is provided with the resonant capacitance 5 that is connected in parallel with electromagnetism drum 2 on electromagnetism drum 2.For the resonant capacitance 5 that overcomes existing electromagnetic oven heating device is single-mode and 2 configurations of electromagnetism drum, only suitable electromagnetic oven has additional in this electromagnetic oven heating device and adjusts electric capacity 6 in the shortcoming of certain power section work.According to the initial design values of resonant capacitance 5, when resonant capacitance 5 was big, adjusting electric capacity 6 can be connected in series with resonant capacitance 5, and was connected in parallel to switch 7 on adjustment electric capacity 6, as shown in Figure 1.When resonant capacitance 5 hour, adjusting 6 of electric capacity can be connected in parallel with resonant capacitance 5, simultaneously, 7 on switch is connected in series with adjusting electric capacity 6, as shown in Figure 2.Among the above-described embodiment, after switch 7 disconnected, the adjustment electric capacity 6 of series connection reduced the capacitance of resonant circuit, makes under the electromagnetic oven low-power section mode of operation, electromagnetism drum 2 and resonant circuit reach configuration preferably, have improved the low-power section heats of electromagnetic oven; And after switch 7 closes, adjustment electric capacity 6 in parallel has improved the total capacitance of resonant circuit, optimized the configuration of electromagnetic oven at high power section electromagnetism drum 2 and resonant circuit, improved the high power section heats of electromagnetic oven, electromagnetic oven with this heater formation, electromagnetism drum 2 and resonant circuit can obtain more excellent association joins, and electromagnetic oven all can be realized preferably the operating state of heating continuously under power requirements at different levels.Electromagnetic oven heating device of the present utility model has efficiency of heating surface height, and is low in energy consumption, saves the advantage of the energy.
