(4) description of drawings
Fig. 1 is the electrical principle block diagram of existing electromagnetic oven;
Fig. 2 is an electrical principle block diagram of the present utility model.
(5) embodiment
As shown in Figure 2, the utility model is a kind of low power consumption standby circuit device of induction cooker, and it comprises filter circuit 1, major loop 2, control circuit 3, DC power supply 4 and single-chip microcomputer 5.The input of filter circuit 1 is electrically connected with the 220V AC power, and AC power is strobed.The output of filter circuit 1 is electrically connected with major loop 2, for major loop 2 provides power supply.Single-chip microcomputer 5 is by control circuit 3 control major loops 2.Filter circuit 1 is electrically connected with DC power supply 4 by diode D2, and DC power supply 4 provides power supply to single-chip microcomputer 5 and control circuit 3.
Improvements of the present utility model are: be provided with single-pole double-throw switch (SPDT) K1 between 220V AC power and filter circuit 1, another contact of K switch 1 is electrically connected with DC power supply 4, be provided with K switch 2 between DC power supply 4 and the control circuit 3, K switch 1 and K switch 2 are respectively by Single-chip Controlling.K switch 1 makes filter circuit 1, major loop 2 and control circuit 3 be in "on" position when working with the setting of K switch 2, is in off-position when standby, thereby reduces stand-by power consumption, energy savings.
Preferably, K switch 1 can be for the change type switch, such as relay; K switch 2 can be electronic switch, such as triode.
Be provided with diode D1 between K switch 1 and DC power supply 4, AC power provides working power for single-chip microcomputer 5 by diode D1 in the halfwave rectifier mode.
The operation principle of the present utility model and the course of work are as follows:
During the electromagnetic oven standby, 1 position is got in the contact of K switch 1, and K switch 2 is in off-state.This moment, filter circuit 1, major loop 2 and control circuit 3 were in the no power state, because not power supply and consumed power not.AC power provides working power for single-chip microcomputer 5 by diode D1 in the halfwave rectifier mode.Under this state, have only single-chip microcomputer 5 and DC power supply 4 consumed powers, the stand-by power consumption of electromagnetic oven can drop to below the 0.5W, meets the energy-conservation proposal of International Energy Agency (IEA).
During electromagnetic oven work, single-chip microcomputer 5 output high level, 2 positions are got in K switch 1 contact, this moment, AC power was powered with way of full-wave rectification, while K switch 2 closures, and filter circuit 1, major loop 2 and control circuit 3 are in "on" position, normal power supply, the electromagnetic oven operate as normal.
The utility model also can be used for other similar electronic equipment and household electrical appliance.
