Technical field
The present invention relates to a kind of power switch system, the power switch system on particularly a kind of electrical appliance, the household electrical appliance.
Background technology
Electrical appliance, household electrical appliance as television set, projector, electromagnetic oven, according to the requirement of the countries concerned's standard, must be provided with an ac power switch on it.The user uses electrical appliance or household electrical appliance to finish the back ordinary practice in mains switch is turned off, and for the electrical equipment with distant control function, people wish just can switching off AC power by remote controller.For realizing this function, prior art adopts mains switch to have electromagnet, by the action of the electromagnet on the remote controller operating power switch, and power cutoff switch at a distance just.This mains switch cost that has an electromagnet is very high, is not suitable for being popularized using.Also have a kind of demand in making the process of electrical appliance, require after main power consumption is partly cut off the power supply in the main frame of electrical equipment, the time-delay of complete machine AC power is turn-offed a little while, as projector, electromagnetic oven, realizes the Circuits System more complicated of this delay switching-off, and cost is also than higher.
Summary of the invention
The purpose of this invention is to provide a kind of electrical appliance power switch system, the technical problem that solve is the cost that reduces with the power switch system of remote controller control, and electrical appliance power switch system has the function that the main frame AC power is cut off in time-delay simultaneously.
The present invention is by the following technical solutions: a kind of electrical appliance power switch system, ac power input end connects mains switch one end, described mains switch adopts long stroke to push away-push away mains switch, another is in parallel with the pair of contact of relay to contact for mains switch, another termination ac/dc power supply of mains switch, the ac/dc power supply is the complete machine control system power supply of electrical equipment, and the complete machine control system outputs signal to AC control circuit, AC control circuit control relay coil electricity and outage.
Complete machine control system of the present invention outputs signal to DC control circuit.
Closing time after mains switch of the present invention is pressed is sent letter to the power supply of complete machine control system, complete machine control system to AC control circuit greater than ac/dc power supply after the mains switch energized
Mains switch of the present invention adopts the KDC-A04-4 type not have the self-locking push-push switch, and relay adopts JQX-14F type high power relay.
AC control circuit of the present invention adopts triode.
DC control circuit of the present invention adopts triode.
The present invention compared with prior art adopts the long stroke push-push switch of no auto-lock function, and with relay control AC power time delayed turn-off, simple in structure, cost is low.
Description of drawings
Fig. 1 is the circuit block diagram of the embodiment of the invention.
Fig. 2 is the circuit theory diagrams of the embodiment of the invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.As shown in Figure 1, the long stroke that electrical appliance power switch system of the present invention is provided with no auto-lock function pushes away-pushes away mains switch S, the termination AC power of mains switch S, another termination ac/dc AC/DC power supply PWM.Another of mains switch S is in parallel with the pair of contact of relay R L to contact.AC/DC power supply PWM has a few road direct current DC outputs, and wherein one the tunnel is the complete machine control system MCU power supply of electrical equipment, and complete machine control system MCU is output signal control AC control circuit AC CTRL and DC control circuit DC CTRL respectively.AC control circuit AC CTRL drives relay, by control relay coil electricity and outage, comes the adhesive and the disconnection of control relay RL contact, thus control and this another switching on and off to contact to contact mains switch S in parallel.DC control circuit DC CTRL outputs control signals to AC/DC power supply PWM, makes AC/DC power supply PWM be operated in holding state or normal operating conditions.
The appliance mains switch course of work of the present invention is as follows:
Start: make its closure by mains switch S, AC/DC power supply PWM starts, and is complete machine control system MCU power supply, and control system MCU makes relay R L closure by AC control circuit AC CTRL, disconnect even at this moment press push-push switch S, complete machine also can continue power supply by relay R L.
Shutdown: press the standby button on remote controller or the complete machine, control system MCU passes through DC control circuit DC CTRL after receiving shutdown command, make AC/DC power supply PWM be operated in holding state, according to setting, also can make relay R L coil blackout by AC control circuit AC CTRL after some seconds in time-delay, thereby relay contact is disconnected, turn-off the AC power of complete machine.
The present invention requires the selection of push-push switch S and relay: 1, the stroke of mains switch S is wanted long enough, with after guaranteeing once to be pressed sufficiently long closing time is arranged, closing time must be sent the time sum that signal, AC control circuit AC CTRL drive relay R L closure to complete machine control system MCU power supply, complete machine control system MCU to AC control circuit ACCTRL greater than AC/DC power supply after the mains switch S energized; 2, safety and withstand voltagely will meet the countries concerned's standard; 3, operating voltage and operating current will meet the requirement of electrical equipment complete machine.
This machine or remote control exchange to close when power supply needs software design and arrange.
As shown in Figure 2, as most preferred embodiment, electrical appliance power switch system of the present invention is applied in group of Konka and is about on the high definition projector of listing, the circuit diagram of the power switch system part of only having drawn among the figure.Mains switch S adopts the KDC-A04-4 type of the Dongguan beneficial Electronics Co., Ltd. of China not have the self-locking push-push switch, and relay R L adopts JQX-14F type high power relay.The course of work of power switch system is as follows:
Start: press mains switch S during start, switch S is connected the back system and is powered on, the work of AC/DC power unit is for control system MCU partly provides+the 5V power supply, before switch S disconnects, the AC CTRL control of MCU mouthful output high level, make AC CTRL triode V1 saturation conduction, relay R L line bag obtains the adhesive of drive current back contact, even at this moment switch S disconnects, the electrical equipment complete machine provides power supply by relay R L, and the electrical equipment complete machine is kept operate as normal.
Shutdown: press the standby button on remote controller or the complete machine, control system MCU controls a mouthful output low level by DC CTRL after receiving shutdown command, DC CTRL triode V2 is ended, voltage on the transmitting tube of optocoupler N1 rises, make AC/DC power supply PWM be operated in holding state, according to setting, MCU also can control a mouthful output low level by AC CTRL after some seconds in time-delay, AC CTRL triode V1 is ended, relay R L line bag can not get the drive current back contact and disconnects, at this moment because of switch S disconnects, so just turn-offed the AC power of complete machine.
