Abstract
The utility model relates to an automatic power off device for standby of an automatic washing machine. The automatic power off device comprises a time-base circuit serving as a main control chip. A high trigger end of the time-base circuit is connected with a first resistor, a second resistor and a first capacitor. The automatic power off device also comprises an audion and the base electrode of the audion is connected with an adjustable resistor. The first capacitor is arranged between the emitting electrode and the collecting electrode of the audion. The audion is connected to the two ends of the first capacitor reversely. The low trigger end of the time-base circuit is connected with a third resistor and a second capacitor, which are connected in parallel. The output end of the time-base circuit is connected with a relay through a fourth resistor. Based on RC delay technology, the automatic power off device enables periodic control signals in the work of the washing machine to make capacitor discharge achieve continuous delay. When the work of the washing machine stops and no control signal is generated, the power supply is cut off after the RC delay for a certain period of time.
Description
Technical field
The utility model relates to a kind of breaker device, especially a kind of automatic washing machine standby automatic power-off device.
Background technology
Country implements when energy-saving and emission-reduction measure, washing machine stand-by power consumption have been had and explicitly called for, and washer operation does not change.At present, the domestic full-automatic washing machine on market is mainly the object that realizes capable of power off in standby state of electric by external controller.And the power switch of controller is mainly divided into two types: one, on controller with the button of an array scanning as " power supply " key, when the forceful electric power plug of washing machine connects after socket, controller carries out array scanning to " power supply " key always, in the time detecting that " power supply " key is pressed, display board enters the show state that powers on; Its two, mechanical power switch, on the forceful electric power wire harness of washing machine, connects a mechanical power switch, when power switch is not closed, rotary drum washing machine controller is in electriferous state not, in the time that power switch is closed, machine enters power-up state.
Above-mentioned these two kinds of switches have its limitation, and for the first switch, if do not pull out the forceful electric power plug of automatic washing machine, controller is just always in running order, has certain power consumption; For the second switch, although can realize zero-power, must user's manual operations, once after user starts and leave after washing machine, in the time that washing finishes, controller or in running order, so cannot realize automation control completely.Advocate in country under the overall background of power-saving technology application, although the power consumption of holding state is very low, but count the quantity of the up to ten million automatic washing machine in the whole nation in, if automatic washing machine can be saved at the electric energy under holding state, achievement is also considerable.
Summary of the invention
The technical problems to be solved in the utility model is: propose a kind of automatic washing machine standby automatic power-off device, do not need external controller, only need on the power circuit of washing machine itself, improve the power consumption just can deduct standby completely time.
The technical scheme that the utility model adopts is: a kind of automatic washing machine standby automatic power-off device, comprise a time base circuit as main control chip, and the high-triggering end of described time base circuit is connected with the first resistance, the second resistance and the first electric capacity; Described device also comprises a triode, and the base stage of described triode connects an adjustable resistance; The first described electric capacity is arranged between the emitter stage and colelctor electrode of triode; Described triode reversal connection is at the first electric capacity two ends; The low triggering end of described time base circuit is connected with the 3rd resistance and the second electric capacity; The 3rd described resistance and the second Capacitance parallel connection setting; The output of described time base circuit is connected with relay by the 4th resistance.
Further, time base circuit described in the utility model, triode, the first resistance, the second resistance and a delay circuit of the first electric capacity composition; Described time base circuit is 555 time base circuits, and its operating voltage is 4.5～18V.
The beneficial effects of the utility model are: adopt RC delay technique, periodic control signal while allowing washing machine work constantly makes capacitor discharge reach the object of " time delay always ", when washing machine work is complete while no longer including control signal, after RC time delay a period of time, cut off the electricity supply.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is circuit theory diagrams of the present utility model.
Detailed description of the invention
With preferred embodiment, the utility model is described in further detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, IC1, BG1, R1, R2, C1 forms a delay circuit, when washing machine power switch is connected, the 2 pin electrical level rising of IC1, now 6 pin are still low, export 3 pin high, relay J 1 adhesive, washing machine energising, the value of C1 has determined delay time (being now set as 2 minutes), start after washing machine, A point receives from signal source (as long as any high level in 1 minute cycle can be provided, as motor control signal etc.), BG1 reversal connection is at C1 two ends, C1 is discharged, 6 pin are always low, when washing machine after hours, C1 is slowly charged, after 2 minutes, 6 pin have been increased to latch voltage, output pin 3 is low level, relay J 1 discharges, washing machine power supply is cut off.Because NE555 operating voltage is wider, be approximately 4.5～18V, this circuit has adaptability widely.The base stage that W1 adjusts BG1 can just provide conducting required voltage.
What in above description, describe is detailed description of the invention of the present utility model, various not illustrating is construed as limiting flesh and blood of the present utility model, person of an ordinary skill in the technical field read after description can to before described detailed description of the invention make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
