The LED indicating circuit is arranged on a PCB (printed circuit board); the circuit comprises a pull-up resistor R1, LEDs, a switch circuit and an MCU (microprogrammed control unit) circuit; and the switch circuit comprises a resistor R2 and a power amplifier Q1 connected in parallel. One end of the pull-up resistor R1 is connected with a power anode VCC, while the other end is connected with a cathode of each LED; an anode of each LED is provided with two paths, wherein one path is connected with the resistor R2 and the other path is connected with an emitting electrode of the power amplifier Q1; and a collecting electrode of the Q1 is grounded, and a base electrode is connected with an output terminal interface P1 of the MCU. The breathing lamps are added onto the induction cooker, the cost is low, the performance is stable and reliable, the appearance is more attractive to appreciate by a user, and more experience can be brought to a user.
Description
Technical field
The utility model relates to a kind of electromagnetic oven, particularly relates to a kind of electromagnetic oven that has breath light.
Background technology
The breath light demonstration has all been adopted in the fast development of electronic communication technology on many electronic products, it can make the LED lamp gradually bright or gradually go out with the frequency of the breath rhythm that is similar to the people.But breath light is mainly used on the electronic products such as mobile TV, but does not use on small household electrical appliances such as electromagnetic oven.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of electromagnetic oven that has breath light is provided, make electromagnetic oven can be when showing gradually bright or gradually go out according to frequency, and the user mode of the demonstration electromagnetic oven of energy simple and fast, for the user visually brings the favorable experience effect, cost is lower, and is stable and reliable for performance.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of electromagnetic oven that has breath light, comprise body of heater, boiler face and control panel, described boiler face is installed in the body of heater surface, control panel is installed on the body of heater by syndeton, control panel comprises control button and LED light, and LED light is fixed by welding on the LED indicating circuit, and reaches the effect of breath light by the control of LED indicating circuit.
LED light reaches the effect of breath light by the control of LED indicating circuit, described LED indicating circuit is arranged on the PCB circuit board, this circuit is made up of pull-up resistor R1, LED light, on-off circuit and the MCU circuit of mutual electrical connection successively, LED light is a light emitting diode, and on-off circuit is composed in parallel by resistance R 2 and power amplifier Q1.The anodal VCC of pull-up resistor R1 one termination power, the negative pole of another termination LED light, positive pole one road connecting resistance R2 of LED light, another road connects the emitter stage of power amplifier Q1, the grounded collector of Q1, base stage links to each other with the output interface P1 of MCU.
Compared with prior art, the beneficial effects of the utility model are: increased breath light on electromagnetic oven, the user can observe user mode more intuitively, and cost is lower, and is stable and reliable for performance, strengthened user's sight, for the user brings more experience.
Description of drawings
Fig. 1 is circuit theory diagrams of the present utility model;
Fig. 2 is a LED indicating circuit structure chart of the present utility model.
The specific embodiment
Purport of the present utility model is to overcome the deficiencies in the prior art, a kind of electromagnetic oven that has breath light is provided, on electromagnetic oven, increased breath light, the user can observe user mode more intuitively, and cost is lower, stable and reliable for performance, strengthened user's sight, for the user brings more experience.Be elaborated with reference to accompanying drawing below in conjunction with embodiment, so that technical characterictic of the present utility model and advantage are carried out more deep annotation.
Schematic diagram of the present utility model as shown in Figure 1, a kind of electromagnetic oven that has breath light, comprise body of heater 2, boiler face 1 and control panel 5, described boiler face 1 is installed in the surface of body of heater 2, control panel 5 is installed on the body of heater 2 by syndeton 6, control panel 5 comprises control button 3 and LED light 4, and LED light 4 is welded on the LED indicating circuit, and LED light 4 reaches the effect of breath light by the control of LED indicating circuit.
LED indicating circuit structure chart of the present utility model as shown in Figure 2, the LED indicating circuit is arranged on the PCB circuit board, this circuit is made up of pull-up resistor R1, LED, on-off circuit and the MCU circuit of mutual electrical connection successively, LED is a light emitting diode, and on-off circuit is composed in parallel by resistance R 2 and power amplifier Q1.The anodal VCC of pull-up resistor R1 one termination power, the negative pole of another termination LED, positive pole one road connecting resistance R2 of LED, another road connects the emitter stage of power amplifier Q1, the grounded collector of Q1, base stage links to each other with the output interface P1 of MCU.LED is LED light 4, and LED is a plurality of, according to the effect different distributions in different positions.
Generally speaking, during the P1 mouth of MCU output high level, the LED lamp goes out, and during output low level, the LED lamp is bright.In this circuit operation, MCU provides lasting square-wave signal for the P1 delivery outlet, this moment, lasting two kinds of alternating states of light on and off appearred in the LED lantern festival, when the frequency of square-wave signal is very high, because persistence of vision factor, the light on and off state human eye identification that the LED lamp is controlled by square-wave pulse less than, allow breath light slowly brighten or the slow effect of deepening so the frequency of the square-wave pulse by control P1 delivery outlet can reach.The square-wave waveform frequency of P1 delivery outlet the time is stable in work, but operating frequency can preestablish, and the dutycycle of output waveform changes, and the on-off circuit that composes in parallel of Q1 and resistance R 2 frequency and the dutycycle that can regulate square-wave pulse.
Although how the utility model realizes that to the electromagnetic oven that has breath light the breath light display effect made clear and complete description by instantiation, but the utility model is not limited only to described embodiment, and to reach the breath light display effect be contingent and all be included among the utility model by simple change circuit structure.
