The utility model provides a low power consumption stand-by induction cooker which can reduce the power consumption in stand-by state to save energy.
Description
Technical field
The utility model belongs to electromagnetic oven.
Background technology
Electromagnetic oven is as a kind of emerging kitchen small household appliances, and with its flames of anger, thermal efficiency advantages of higher is popularized very soon.But in traditional electromagnetic oven, for touch switch closes, when closing electromagnetic oven, just closed heating system, (AC220V) do not cut off the electricity supply yet.Under the situation of standby, internal circuit is still at consumed power, and conventional electromagnetic oven stand-by power consumption is that power consumption is bigger about 5W, the waste electric energy.
Under holding state, owing to do not cut off main power source, under ideal case, most electronic components are still in work.Significantly reduced the use life life-span of electromagnetic oven.Under the situation that electronic component lost efficacy, may cause unpredictable situations such as electromagnetic oven spontaneous combustion, bring economic loss to the user.
Summary of the invention
Existing electromagnetic oven power consumption under holding state is big in order to overcome, the deficiency of waste electric energy, and the utility model provides a kind of can significantly reduce the power consumption under the holding state, the low-power consumption standby electromagnetic oven of saves energy.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of low-power consumption standby electromagnetic oven, comprise the electromagnetic oven main circuit, main power source, control chip MCU and key circuit in order to the work of control electromagnetic oven, described main power source connects the electromagnetic oven main circuit, described main power source connects the power supply tie-in line, described control chip MCU connects key circuit, described electromagnetic oven also comprises in order to civil power is converted to the auxiliary power of low-voltage power supply, described power supply tie-in line is the auxiliary connection power supply also, described auxiliary power connects control chip MCU, be provided with controlled switch between described power supply tie-in line and the main power source in order to control main power source break-make, described controlled switch connects control chip MCU, described control chip MCU comprise be used to receive the standby push button signalling after the control controlled switch disconnect, standby/start the control module of control controlled switch closure behind the start push button signalling.
As preferred a kind of scheme: described controlled switch is relay or controllable silicon.
Technical conceive of the present utility model is: when electromagnetic oven enters holding state, and the output of MCU non-relay (controllable silicon) control signal, the main power circuit no current has only auxiliary power to MCU and key circuit power supply.Greatly reduce stand-by power consumption.
Also because of the main power circuit no current, no current flows through on the high voltage device on the electromagnetic oven main power source, has prolonged the service life of electromagnetic oven simultaneously.Also eliminated because of high-voltage capacitance loses efficacy and caused danger on fire.
The beneficial effects of the utility model mainly show: 1, significantly reduce power consumption, saves energy under the holding state; 2, prolonged the service life 3 of electromagnetic oven, also eliminated because of high-voltage capacitance loses efficacy and caused danger on fire.
Description of drawings
Fig. 1 is the circuit diagram of low-power consumption standby electromagnetic oven.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
With reference to Fig. 1, a kind of low-power consumption standby electromagnetic oven, comprise the electromagnetic oven main circuit, main power source 1, control chip (MCU) 2 and key circuit 3 in order to the work of control electromagnetic oven, described main power source 1 connects the electromagnetic oven main circuit, described main power source 1 connects the power supply tie-in line, described control chip (MCU) 2 connects key circuit 3, described electromagnetic oven also comprises in order to civil power is converted to the auxiliary power 4 of low-voltage power supply, described power supply tie-in line is auxiliary connection power supply 4 also, described auxiliary power 4 connects control chip (MCU) 2, be provided with controlled switch 5 between described power supply tie-in line and the main power source in order to control main power source break-make, described controlled switch 5 connects control chips (MCU) 2, described control chip (MCU) 2 comprise be used to receive the standby push button signalling after the control controlled switch disconnect, standby/start the control module of control controlled switch closure behind the start push button signalling.
Described controlled switch 2 is relay or controllable silicon.
The course of work of present embodiment is: connect power supply when electromagnetic oven, before the heating work, be not called holding state.After electromagnetic oven entered holding state, controlled switch 5 (but relay or silicon control) was in open-circuit condition, cut off main power source (rectification circuit and heating circuit) loop.Have only this moment auxiliary power to give control chip MCU power supply, power consumption can be lower than 1W.
When pressing the start button, control chip MCU receives starting-up signal, output relay (controllable silicon) Continuity signal, connect main power circuit, can realize normal heating function, when the user presses the shutdown button, control chip MCU output relay (controllable silicon) open circuit signaling, cut off main power circuit, enter holding state.Whole process does not change traditional use habit of client.
