As described in Figure 1, foregoing circuit 100 also includes the 7th resistance R7, and one end of the 7th resistance R7 switchs with first respectively
Second end 2 of pipe and the 3rd end 9 of the 3rd switching tube connect, and the other end of the 7th resistance R7 is connected with washing machine L, and i.e.
One switching tube and the 3rd switching tube connect washing machine L by the 7th resistance R7.
Disconnecting after triggering switch is triggered Guan Bi and maintenance the first Preset Time, boot-strap circuit conducting and shutdown circuit 30 are disconnected
Opening, power supply T output is in open state to washing machine L, washing machine L, thus realizes a key switch machine, operation letter
Single, it is easy to user uses, in addition, it is not necessary that touch forceful electric power parts, require to reduce to the degree of protection of product.
The control circuit 100 of the embodiment of the present invention can also realize a key shutdown, specifically, is triggered Guan Bi triggering switch
And disconnect after maintaining the second Preset Time, boot-strap circuit disconnects and shutdown circuit conducting, and power supply T stops output to washing
Clothing machine L, washing machine L are in off-mode, thus realize a key shutdown.Wherein, the second Preset Time is preset more than first
Time, it is believed that be short by triggering switch S1 during start, and pass through when shutdown long by triggering switch S1 realization, also
That is, hardware realize short by triggering switch S1 start, long by triggering switch S1 shutdown, it is not take up software resource.
Specifically, in a particular embodiment of the present invention, the first switching tube is the first NPN type triode NPN1；Second switch
Pipe is P-channel metal-oxide-semiconductor PMOS1；3rd switching tube is the second NPN type triode NPN2.
Referring to Fig. 1, the action sequence for a key switch machine control circuit 100 of washing machine of foregoing circuit structure is entered
Row describes in detail.
Before power supply electrifying, trigger switch S1 and be off, audion in first end 1 such as Fig. 2 of the first switching tube
Base stage be 0V, the first switching tube is in medium state, and the base stage of the second i.e. audion of end 8 of the 3rd switching tube is 0V,
Three switching tubes are in cut-off state, the first end 4 and the voltage i.e. Vgs=0V of the second end 5 of second switch pipe such as p-type metal-oxide-semiconductor,
Metal-oxide-semiconductor is in cut-off state, and the voltage LOAD+ of output to washing machine L is without electricity.
Short by triggering switch S1, now power supply T input voltage 5V is loaded into the first switching tube Q1 by the first resistance R1
The the first end i.e. base stage of audion, the first switching tube turns at once, the second switch pipe i.e. Vgs=-5V of metal-oxide-semiconductor, metal-oxide-semiconductor
In the conduction state, the voltage LOAD+ of output to washing machine L is 5V, and+5V is that electric capacity C fills by the 5th resistance R5 simultaneously
Electricity, the first Preset Time but triggering switch S1 is only triggered, it is believed that being short triggering, the charging voltage of electric capacity C is not enough to rise
Up to can turn on the base stage of the second i.e. audion of end 8 of the 3rd switching tube Q3, so the 3rd switching tube is still in cut-off state,
Now washing machine L obtains electric work.
After triggering switch S1 is released, output voltage LOAD+ maintains the conducting shape of the first switching tube by the 7th resistance R7
State, the 3rd switching tube keeps cut-off state, and second switch pipe is held on, and washing machine L maintains electricity, is constantly in work
State.
Long by triggering switch S1, now the input voltage 5V of power supply T is loaded onto the first switching tube by the 3rd resistance R3
The base stage of the first i.e. audion of end 1, the first switching tube turns at once, the Vgs=-5V of second switch pipe such as metal-oxide-semiconductor,
Second switch pipe is in the conduction state, output voltage LOAD+=5V, and meanwhile, electric capacity C is charged by+5V by the 5th resistance R5,
Due to trigger switch S1 be triggered the second Preset Time i.e. grow by, the charging voltage of electric capacity C will can be led after some time
The base stage of logical 3rd switching tube, the i.e. the 3rd switching tube conducting, now first opens the light the base stage of pipe by the 3rd end of the 3rd switching tube
The 9 i.e. colelctor electrode of audion controls to be pulled low to 0V, the first switching tube cut-off, washing machine L dead electricity.
After triggering switch S1 is released, due to the energy storage effect of electric capacity C, the 3rd switching tube maintains conducting state, and first opens
Closing pipe and keep cut-off state, second switch pipe keeps cut-off state, and washing machine L is in off-mode.
Wherein, the setting of response time that is first Preset Time and the second Preset Time that trigger switch S1 can be by adjusting electricity
The value holding C is changed.The input voltage of the control circuit 100 of the embodiment of the present invention can use, no within the specific limits
Being confined to+5V, other voltage ranges need to adjust parameter.
Such as Fig. 2, the whole sequential of the Washing machine switch machine control circuit of the embodiment of the present invention is summarised as: T1, power supply electrifying；
T2, short pressing trigger switch S1；T3, washing machine obtain electric；T4, long pressing trigger switch S1；T5, washing machine power-off.
Sum it up, the switching on and shutting down control circuit for washing machine of the embodiment of the present invention, it is achieved that light current one key switch machine control
System, specifically on hardware, short realizes start by triggering switch S1, long realizes shutdown by triggering switch S1, is not take up software
Resource, circuit structure is simple, uses device cheap, and debugging is simple, is not exposed to forceful electric power parts, the protection to product
Class requirement reduces, it is easy to user uses.
The switching on and shutting down control circuit for washing machine based on above-described embodiment, another aspect of the present invention embodiment proposes one and washes
