Abstract
The invention relates to a microwave oven start control method, which comprises the following steps: (1) a controller starting to work and detect whether the AC is over zero, if so, the controller delaying by X ms, otherwise returning to re-detect; (2) the controller delaying after X ms, triggering a relay, otherwise returning to re-detect; (3) the controller sending a control signal with a time length of Y ms to trigger the relay communication after the relay is triggered, when the time is Y ms, turning off the relay, otherwise returning to re-detect; (4) the controller sending the signal with X-1 ms and Y+1 ms, when Y is equal to 8 ms, the program ending, the controller always sending the control signals to trigger the relay, at this time the microwave over opening, if Y is mot 8 ms, then returning to re-detect. Through the above technology scheme, the starting, the microwave oven start control method is used to slowly increase the current connected to a magnetic control tube end, achieve the soft starting of the magnetic control tube and reduce the starting noise.
Description
Technical field
The present invention relates to a kind of micro-wave oven and start control method.
Background technology
At present, the micro-wave oven of using on market is all to control the startup of magnetron and the break-make of magnetron with electromagnetic relay, a termination control signal of electromagnetic relay, a termination magnetron.When micro-wave oven starts, host computer, to control signal of control end, is realized the other end (connecing magnetron end) conducting, magnetron work moment can produce surge current, due to galvanomagnetic-effect, the surge of this moment can produce moment high-intensity magnetic field, inhale inner chamber body steel plate produce " rub-a-dub " noise.
Summary of the invention
The object of the present invention is to provide a kind of micro-wave oven to start control method, this control method can better be controlled magnetron and start, and abates the noise.
For achieving the above object, the present invention has adopted following technical scheme: a kind of micro-wave oven starts control method, the startup control device of described micro-wave oven comprises solid-state relay, one end of solid-state relay is connected with the output of controller, the other end of solid-state relay is connected with magnetron by transformer, comprises the steps:
(1) controller is started working, and detects whether zero crossing of alternating current, and result is for being delaying time of controller X millisecond, otherwise returns to detection again;
(2) delaying time of controller is to X millisecond, and trigger relay, detects otherwise return again;
(3) after trigger relay, controller sends a control signal trigger relay conducting that time span is Y millisecond, after the full Y millisecond of timing, turn-offs relay, otherwise return again, detects;
(4) controller sends X and successively decreases 1 millisecond, the signal that Y is cumulative 1 millisecond, and EP (end of program) when Y equals 8 milliseconds, the controller trigger relay that always transmits control signal, at this moment micro-wave oven is opened, if during 8 milliseconds of Y less thaies, returns again and detects.
As shown from the above technical solution, the present invention slowly increases by said method the electric current that connects magnetron end, realizes the soft start of magnetron, reduces and starts noise.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention;
Fig. 2 is FB(flow block) of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
A kind of micro-wave oven as shown in Figure 1 starts control method, and the startup control device of described micro-wave oven comprises solid-state relay 1, and one end of solid-state relay 1 is connected with the output of controller 2, and the other end of solid-state relay 1 is connected with magnetron 4 by transformer 3.Solid-state relay 1 of the present invention is alternating current zero crossing type solid-state relay.
In other words namely one end of solid-state relay 1 connects the control signal of host computer, the other end connects magnetron 4 by transformer 3, this relay is random connection, zero crossing turn-offs type, by programme-control, host computer sends the control signal of different dutycycles to signal end, host computer sends the control signal that the angle of flow increases gradually, thereby the electric current of the other end (connecing magnetron end) is slowly increased, thereby realize magnetron 4 soft starts, suppress the generation of surge current, reduced the noise while starting.
A kind of micro-wave oven as shown in Figure 2 starts control method, comprises the steps:
(1) controller is started working, and detects whether zero crossing of alternating current, and result is for being delaying time of controller X millisecond, otherwise returns to detection again;
(2) delaying time of controller is to X millisecond, and trigger relay, detects otherwise return again;
(3) after trigger relay, controller sends a control signal trigger relay conducting that time span is Y millisecond, after the full Y millisecond of timing, turn-offs relay, otherwise return again, detects;
(4) controller sends X and successively decreases 1 millisecond, the signal that Y is cumulative 1 millisecond, and EP (end of program) when Y equals 8 milliseconds, the controller trigger relay that always transmits control signal, at this moment micro-wave oven is opened, if during 8 milliseconds of Y less thaies, returns again and detects.
Be exactly when starting to start specifically, controller detects the crossover point signal of alternating current, delaying time of controller X millisecond after crossover point signal detected, after time delay X millisecond, controller sends a flat trigger relay conducting of control signal (namely high level signal) that time span is Y millisecond, after the full Y millisecond of timing, turn-off relay, at this moment X successively decreases 1 millisecond, cumulative one millisecond of Y, termination routine when Y equals 8 milliseconds, trigger relay transmits control signal always, micro-wave oven is opened, the electric current of microwave in this method when starting increases progressively gradually, so substantially there is no the appearance of noise.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection domain of the claims in the present invention book.
