Also have, No. 5 terminals that 2 ends of high-tension transformer (40) are gone up the 1st inductance coil (40a) that constitutes are connected the anode and the F end of the 1st diode (D1), the minus earth of the 1st diode (D1).Hold No. 7 terminal ground connection of going up the 2nd inductance coil (40b) that constitutes 2 times of high-tension transformer (40) simultaneously.
At this moment, the operation of the ON/OFF (on/off) of above-mentioned the 1st relay (20) and the 2nd relay (30) is finished by the microcontroller (not shown).
The operation principle of each control element in the above-mentioned loop below is described.
The once end of mesohigh transformer of the present invention (40) is provided with the 1st relay (20) and the 2nd relay (30), by the operation of above-mentioned the 1st relay (20) and the 2nd relay (30), regulate the electric current setting of outside addition power supply to high-tension transformer (40).That is,, give the once end addition minimum current value of high-tension transformer (40) by the operation of above-mentioned the 1st relay (20); By the operation of above-mentioned the 2nd relay (30), give the current value relatively large current value of the once end addition of high-tension transformer (40) than the 1st relay (20) addition.

Fig. 3 illustrates the 1st example that adds heat energy control of micro-wave oven among the present invention.
As shown in the figure, during the addition power supply, the 1st relay (20) is started working in the loop shown in Figure 2.At this moment, owing to only drive above-mentioned the 1st relay (20), the current value that is added on the high-tension transformer (40) is 15A.If addition power supply in the loop, and the 1st relay (20) and the 2nd relay (30) be when working simultaneously, and the current value that is added on the high-tension transformer (40) then is 17A.
Here, when the 2nd relay (30) stops under the driving condition, the ventilation motor (not shown) will drive then.At this moment, the permission current value of above-mentioned ventilation motor (not shown) is 1.5A.
The reason that above-mentioned the 2nd relay (30) and ventilation motor (not shown) do not drive simultaneously is because the permission current value of the middle addition of high-tension transformer (40).Drive under the situation of ventilation motor (not shown) when above-mentioned the 2nd relay (30) drives, will exceed the current value (17A) that product allows, so can not drive simultaneously.Therefore, if will drive the ventilation motor (not shown) time, then be arranged to only be permitted the 1st relay (20) work, thereby operate in the permission current value.
Promptly, under the microwave cooked situation of single execution, the 1st relay (20) is started working, simultaneously the 2nd relay (30) is also worked and is quit work behind the certain hour (being 1 minute in the example of the present invention), only drives the 1st relay (20) subsequently and go up addition at high-tension transformer (40) to allow electric current (about 15A).In addition, when above-mentioned the 2nd relay (30) stopped (off) state, the ventilation motor (not shown) drove immediately, at this moment was used to drive above-mentioned ventilation motor (not shown) and the permission current value of addition is 1.5A.
Here, the gas and the hot gas that produce when the 1st relay (20) and the 2nd relay (30) are worked in initial 1 minute will be discharged to the outside by driving the ventilation motor (not shown).Simultaneously, stop (off) by the 2nd relay (30) reduces the permission current value that is added on the high-tension transformer (40).When if the ventilation motor (not shown) stops (off) again and drives in 1 minute, as shown in the figure, from the primary power added state to thereafter 1 minute in, the 2nd relay (30) will drive again.
After 1 minute, the 2nd relay (30) stops to drive and is only permitted the 1st relay (20) work, makes the current value that is added on the high-tension transformer (40) be lower than original state relatively from original state to the 2 relay work.Therefore, under the situation that is no more than permission current value (17A), can drive ventilation motor simultaneously.
Fig. 4 points out out the 2nd example that adds the heat energy control device of micro-wave oven among the present invention.
As shown in the figure, during the addition power supply, the 1st relay (20) is started working in the loop shown in Figure 2.At this moment, owing to only drive above-mentioned the 1st relay (20), the current value that is added on the high-tension transformer (40) is 15A.Ruo Dangdi 1 relay (20) and the 2nd relay (30) are when working simultaneously, and the current value that is added on the high-tension transformer (40) then is 17A.Therefore, addition power supply and in the loop according to the work starting point of the 1st relay (20) and the 2nd relay (30), the permission current value that is added on the high-tension transformer (40) will change.
As shown in Figure 4, when driving the 1st relay (20), be added to the electric current of about 15A on the high-tension transformer (40).When driving the ventilation motor (not shown) when Ruo Dangdi 1 relay (20) drives, then add the electric current that needs 1.5A in addition.As a result, total limit value of input current is below the 17A in the loop, so can reach stabilized driving.
As mentioned above, when the 1st relay (20) and ventilation motor (not shown) drive simultaneously, the state of the 2nd relay (30) is made as and stops (off) state, thereby the input current of going up addition of once holding of high-tension transformer (40) is reduced in total limit value (about 17A).
In addition, when the state of ventilation motor (not shown) for to stop under the situation of (off) state, the 1st relay (20) and the 2nd relay (30) will be worked simultaneously.The result, with by only driving the power supply of the 1st relay (20) addition, drive magnetron (50) heater of etc.ing and in cabinet supply add heat energy and compare, when driving the 1st relay (20) and the 2nd relay (30) simultaneously, by the power drives magnetron heaters such as (50) of addition, can produce and bigger add heat energy and supply in the cabinet.
Therefore, by controlling the work starting point of the 1st relay (20) and the 2nd relay (30), and then the current value of addition in the control loop, and reach the height output that adds heat energy in the cabinet thus.
As mentioned above, the present invention is with the current value of addition in the regulating loop, and then the heat energy that adds of output in the adjusting control cabinet is its basic technological thought.
