Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail: Fig. 2 can control loop figure for micro-wave oven output of the present invention.Fig. 3 can the control procedure view for micro-wave oven output of the present invention.At first, the annexation to control loop among Fig. 2 is described as follows: this loop comprises high-tension transformer 30 and the 1st relay 10 and the 2nd relay 20.Above-mentioned relay is connected on the once end of high-tension transformer 30, the switch of control power supply.In addition, No. 4 terminals that are formed on the 1st coil 30a on high-tension transformer 30 secondary terminals are connected with a side of magnetron 40.No. 6 terminals that are formed on the 2nd coil 30b on high-tension transformer 30 secondary terminals are connected with the opposite side of high-voltage capacitance C.The two ends of high-voltage capacitance C connect resistance R, and the opposite side of high-voltage capacitance C is connected with the opposite side of magnetron 40.Magnetron 40 ground connection.
In addition, on high-tension transformer 30 secondary terminals, No. 5 terminals of the 1st coil 30a are connected with the positive pole of the 1st diode D1, and the minus earth of the 1st diode D1.In addition, No. 7 terminal ground connection of the 2nd coil 30b that forms on high-tension transformer 30 secondary terminals.
The on-off operation of the 1st relay 10 and the 2nd relay 20 is controlled by microcomputer.
Control procedure to above-mentioned control loop is described as follows: energized, by the culinary art item that the user selects, magnetron 40 and electric hot plate are started working.That is, microcomputer drives magnetron 40, detects the culinary art that whether has arrived with user's input and orders corresponding design temperature or time.If arrived design temperature or time corresponding and the culinary art order, just press the certain hour driving of on-off electric hot plate at interval, as shown in Figure 3,, carry out the ON/OFF operation at interval by certain hour the electric heating of in cooking cavity, exporting.In addition, the open/close output procedure of electrical heat energy is performed until till the culinary art end.
Simultaneously, after the energized, high-tension transformer 30 once end is switched on power supply the time, power supply can be added in high-tension transformer 30 and once hold on the 1st relay 10 and the 2nd relay 20 that is connected.Along with energized, if the 1st relay 10 is in the state of unlatching, power supply can be added on the secondary terminals of high-tension transformer 30, if be in closing state, then power supply can not be added in the secondary terminals of high-tension transformer 30.Equally, if the 2nd relay 20 is in the state of unlatching, power supply can be added on the secondary terminals of high-tension transformer 30, if be in closing state, then power supply can not be added in the secondary terminals of high-tension transformer 30.
The 1st relay 10 is in the state of unlatching, and the 2nd relay 20 is in closing state, and then power supply can be added on the secondary terminals of high-tension transformer 30, to magnetron 40 power supplies.Like this, be in the state of unlatching at the 1st relay 10, the 2nd relay 20 is under the closing state, to magnetron 40 power supplies, makes it export microwave in cooking cavity.Afterwards, when the 1st relay 10 is in closing state, stop power supply within a certain period of time.Like this, press certain hour ON/OFF at interval, to magnetron 40 power supplies.
Like this, along with the 1st relay 10, microwave is exported in 40 power supplies of ON/OFF magnetron in cooking cavity, in the cycle shown in the 1st relay 10 among Fig. 3, export in cooking cavity.
The 1st relay 10 is in closing state, and the 2nd relay 20 is in the state of unlatching, and then power supply can be added on the secondary terminals of high-tension transformer 30, to magnetron 40 power supplies.Like this, be in closing state at the 1st relay 10, the 2nd relay 20 is in the state of unlatching, to magnetron 40 power supplies, makes it export microwave in cooking cavity.Afterwards, stop within a certain period of time to magnetron 40 power supplies.Like this, press certain hour ON/OFF at interval, to magnetron 40 power supplies.
Like this, along with the 2nd relay 20, ON/OFF is exported microwave to magnetron 40 power supplies in cooking cavity, in the cycle shown in the 2nd relay 20 among Fig. 3, export in cooking cavity.
As shown in Figure 3, along with the 1st relay 10 and the 2nd relay 20 alternately are in the state of unlatching, export microwave continuously.That is, in integrated mode, electric hot plate is pressed certain hour at interval by ON/OFF, exports electrical heat energy in cooking cavity.Simultaneously, under the effect of the 1st relay 10 and the 2nd relay 20,, allow magnetron 40 export different heat energy to the different power supply of magnetron 40 supplies.
Thereby the energy that produces with the conventional art microwave merely is supplied to the situation in the cooking cavity different with open/close state, among the present invention, presses certain hour output continuously at interval with different separately heat energy, till culinary art finishes.
Here, the heat energy size of exporting in cooking cavity is as the criterion with reference current value, controls.
In sum, the present invention with in cooking cavity continuously output to add heat energy be basic fundamental thought.Particularly, by alternately ON/OFF is to the magnetron power supply, the output energy of controlled microwave allows microwave continuous export in cooking cavity with this.
Scope of authority of the present invention is not limited to the foregoing description, should make an explanation based on right request scope.Indubitable, in basic fundamental thought range of the present invention, also can there be improving one's methods of a lot of aspects.
