Abstract
The utility model discloses a double-control induction cooker comprising a central controller, a fire regulating switch, a power switch, a frequency modulation circuit and a heating coil, wherein the fire regulating switch, the power switch and the frequency modulation circuit are respectively connected to the central controller; the frequency modulation circuit is connected to the heating coil; the fire regulating switch comprises a coarse tuning gear switch and a fine tuning switch; and the coarse tuning gear switch and the fine tuning switch are respectively connected to the central controller. Through double-switch control, the power of the induction cooker disclosed by the utility model can be controlled through the two switches separately or together, and when one of the switches is out of work, the power of the induction cooker can be regulated by the other switch; more fire regulating gears are outputted through the fine tuning switch to carry out power compensation to the coarse regulating switch, so as to meet cooking demands on more fire powers, thus overcoming such a shortcoming of a conventional induction cooker as less output gears, and the induction cooker can achieve effect of a conventional fuel cooker; and the induction cooker is good in stability and reliability, and is quite adapted to a commercial induction cooker used in severe use environments.
Description
[technical field]
The utility model relates to a kind of electromagnetic oven.
[background technology]
Behind hotel, kitchen starts to adopt business electromagnetic stove to substitute traditional gas-cooker gradually at present, because business electromagnetic kitchen range has flames of anger heat radiation, does not consume oxygen, do not produce waste gas, therefore being applied in kitchen can be kitchen environmental protection more, health, health behind hotel, and reduced environment temperature, allow cook be cooked in happy culinary art healthily in the environment of safety and comfort.Above conventional commercial magnetic kitchen range, all to only have a fire control switch, for example magnetic switch, turn-knob potentiometer etc., due to the environment for use very severe of commercial induction cooker in kitchen, oil smoke aqueous vapor is very large, and gauge tap is easy to damage, affect stability, the reliability of product, and then affect the universal of commercial induction cooker.
[summary of the invention]
The purpose of this utility model is to provide a kind of more reliability and durability electromagnetic oven for above-mentioned technical problem.
A kind of double control electromagnetic stove, comprise central controller, firepower by-pass cock, power switch, FM circuit, heating spool rest, firepower by-pass cock, power switch and FM circuit are connected respectively central controller, FM circuit connects heating spool rest, and described firepower by-pass cock comprises coarse adjustment driving switch and accurate adjustment switch, and coarse adjustment driving switch and accurate adjustment switch are connected respectively to central controller.
Described driving switch is many grades of magnetic switch.Described accurate adjustment switch is code switch.
Double control switch also comprises the display screen being connected with central controller, to show performance number, on off state and machine state etc.
Described heating spool rest is connected with current detection circuit, and detection signal is connected to central controller.
The utility model adopts biswitch control, the power of electromagnetic oven is independent or cooperation control by two switches, and regulate electromagnetic oven power by another switch when a switch damage therein, can export more fire-regulating gear by accurate adjustment switch, coarse adjustment switch is carried out to power back-off, meet the culinary art demand of more firepower, thereby overcome the drawback of traditional electromagnetism stove power output gear deficiency, reach in the use the effect of traditional fuel kitchen range, and the working environment in lifting kitchen, reduce all kinds of noxious emissions, stability, good reliability, more adapt to the severe environment for use of commercial induction cooker.
[accompanying drawing explanation]
Accompanying drawing 1 is circuit diagram of the present utility model.
[specific embodiment]
Below in conjunction with the specific embodiment, the utility model is described in further detail.
Double control electromagnetic stove as shown in Figure 1, comprises MCU, six grades of magnetic switch S1, code switch S2, power switch P, FM circuit, heating spool rest L, display screen D.Six grades of magnetic switch S1, code switch S2, power switch P, FM circuit, display screen D connects respectively MCU.FM circuit comprises IGBT pipe, pipe resonant capacitance C2, IGBT pipe and resonance capacitor C 2 and heating spool rest L composition oscillation circuit, IGBT pipe is connected with and drives chip U, drive chip U to connect MCU, MCU is to driving chip U transmitted signal, by driving chip U to control IGBT pipe.
Described heating spool rest L is connected with current detection circuit T, and detection signal is connected to MCU, and current detection circuit comprises inductance coil and rectifier bridge.
Alternating current 220V AC is by after bridge rectifier DB1 rectification, then the direct current that obtains VDD310VDC after capacitor C 1 is after filtering as heating power supply.
The utility model is worked as two switches and is all effectively, can select gear coarse adjustment electromagnetic oven power value by six grades of magnetic switch S1, code switch S2 accurate adjustment electromagnetic oven power value, then send corresponding pulse signal to FM circuit according to different capacity value, FM circuit and heating spool rest produce resonance and realize heating.In the time of one of them switch failure, control separately electromagnetic oven by another effective switch.
On the utility model is described in detail, the above, be only the preferred embodiment of the utility model, do not limit the utility model practical range, be allly to do impartial change and modify according to the application's scope, all should still belong in the utility model covering scope.
