Abstract
The utility model discloses a take overcharge protection built -in power supply formula rice cooker control circuit belongs to tame electric installation technical field. This control circuit comprises rice cooker operating circuit, battery, overcharge protection switch, switch control circuit and various circuit component. Control circuit is connected with the power, and the rice cooker is normally worked, and the power still charges to the battery simultaneously, and when storage battery microcomputer reached furthest, control circuit's electric current will change, and this moment is through the disconnection of switch control circuit control overcharge protection switch, when control circuit and power supply disconnection, on -off controller control overcharge protection switch closure, the battery continued to supply power to the rice cooker operating circuit this moment. The utility model discloses can make the rice cooker still can continue work when the in -process of cooking has a power failure, overcharge protection circuit's use in addition guarantees that the battery is in safe operating condition, can effectively lengthen the life of battery, and this control circuit configuration is simple, the maintenance is convenient, can install and use in various rice cooker.
Description
Technical field
This utility model is related to a kind of control circuit of electric rice cooker, more particularly to a kind of band overcharges protection built-in power formula electricity meal
Pot control circuit, belongs to home appliance technical field.
Background technology
At present most of families cooking electric cooker of all use, and nearly all Domestic Electric Cooker is all the outside for adopting
Power supply is powered, this power-supplying forms work of single employing, will just prevent electric cooker from entering once there is power-off condition
Capable work of cooking, causes to live to obtain greatly inconvenience.Be powered if it is considered that internal electric source is installed to electric cooker simultaneously, also exist
Accumulator overcharges the problems such as may causing security incident, so currently needing a kind of safe and reliable multipath energy supply in a hurry
Electric cooker is solving the above problems.
The content of the invention
For the deficiencies in the prior art, this utility model provides a kind of simple structure, easy to maintenance,
The control circuit for making electric cooker still work on when having a power failure during cooking, is asked with solving above-mentioned technology
Topic.
This utility model is achieved through the following technical solutions to reach object above：There is provided a kind of band to overcharge
Protection built-in power formula control circuit of electric rice cooker, the control circuit by electric cooker operating circuit, accumulator, overcharge protection switch,
ON-OFF control circuit and various components composition, it is characterised in that：Control circuit is connected with power supply, and electric cooker is carried out normally
Work, while power supply is also charged to accumulator, when accumulator electric-quantity reaches to greatest extent, the electric current of control circuit will
Change, protection switch disconnection is overcharged by ON-OFF control circuit control now；When control circuit is disconnected with power supply, switch control
Device control processed overcharges protection switch closure, and now accumulator continues to power electric cooker operating circuit.
Described band overcharges protection built-in power formula control circuit of electric rice cooker, it is characterised in that：The ON-OFF control circuit
Mainly it is made up of current collection circuit, logic control circuit and switch controller, current collection circuit collects control circuit electric current
Variable signal, is then transferred to logic control circuit, and logic control circuit passes through on-off control after process is analyzed to signal
Device control overcharges protection switch and disconnects and closure.
The beneficial effects of the utility model are：Electric cooker can be made still to work on when having a power failure during cooking,
The use of overcharge protection circuit in addition, it is ensured that accumulator is in safe work state, can effectively extend the service life of accumulator,
It is the control circuit simple structure, easy to maintenance, can install and use in various electric cooker.
Description of the drawings
Fig. 1 is schematic diagram of the present utility model.
In figure：1. to overcharge 4. microswitch 5. of protection switch signal lighties 6. of cooking electric for 2. diode 3. of power supply
Resistance 7. is incubated 10. high power electrothermal pipe of signal lighties 8. accumulator, 9. temperature detect switch (TDS), 11. small power electric heat pipe
12. ON-OFF control circuit, 13. electric cooker operating circuit.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Protection built-in power formula control circuit of electric rice cooker is overcharged referring to a kind of bands of Fig. 1, the control circuit is worked by electric cooker
Circuit, accumulator, overcharge protection switch, ON-OFF control circuit and various components composition.Control circuit and power supply（1）Even
Connect, electric cooker carries out normal work, while power supply（1）Also to accumulator（8）It is charged, works as accumulator（8）Electricity reaches most
During limits, the electric current of control circuit will change, now by ON-OFF control circuit（12）Control overcharges protection switch
（3）Disconnect；Control circuit and power supply（1）During disconnection, switch controller control overcharges protection switch（3）Close, now accumulator
（8）Continue to electric cooker operating circuit（13）Power supply.
The ON-OFF control circuit（12）Mainly it is made up of current collection circuit, logic control circuit and switch controller,
Current collection circuit collects control circuit current changing signal, is then transferred to logic control circuit, and logic control circuit is to letter
Control to overcharge protection switch by switch controller after number being analyzed process（3）Disconnect and closure.
The above is specific embodiment of the utility model, but this utility model is not limited to above example, also
Can there are various change and improvement, all replacements made within spirit of the present utility model and principle and improvement, be all contained in
Within protection domain of the present utility model.
Claims (2)
