Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.Following examples are not formed restriction of the present utility model.
As shown in Figure 1, a kind of door-opening electrification circuit, comprise power subsystem, microswitch SW, relay R L and control unit, the input of power subsystem accesses civil power by microswitch SW, the output connection control unit of power subsystem and relay R L, for control unit and relay R L power, control unit connects the control end of relay R L, the open and close of control relay RL switch, relay R L switch is in parallel with microswitch SW.
A kind of door-opening electrification circuit of the present embodiment, control unit adopts MCU chip, one end of microswitch SW is connected with the live wire L of civil power, the other end of microswitch SW is connected with the first input end e of power subsystem, second input f of power subsystem is connected with the zero line N of civil power, and relay R L is in parallel with microswitch SW.First output g of power subsystem is connected, for MCU chip and relay R L power with MCU chip with relay R L; Relay R L control signal input m is connected with MCU chip.The live wire L of the switch one termination civil power of relay R L, the switch other end of relay R L is connected with power subsystem first input end e.
Fig. 2, Fig. 3, Fig. 4 show the structural representation of the washing machine adopting above-mentioned door-opening electrification circuit, comprise washing machine body 1 and door for washing machine 2, also comprise door-opening electrification circuit and are located at the eccentric wheel 3 of door for washing machine 2 rotating shaft place; Microswitch SW is arranged on the surface frame for washing machine on eccentric wheel 3 side, and be with movable eccentric wheel 3 to rotate when door for washing machine 2 opens and closes, the rotation of eccentric wheel 3 triggers the switch of microswitch SW.The output g of power subsystem is connected with MCU chip and relay R L, for MCU chip and relay R L power; The control signal input m of relay R L is connected with washing machine MCU chip.
Microswitch SW two contacts are in parallel with relay R L two switch contacts, the L line of microswitch SW mono-termination civil power input, one end connects power subsystem in addition, and the N line of civil power directly accesses power subsystem, power subsystem is when L, N input simultaneously, just can carry out work, export the vdd voltage required for MCU chip work.
The present embodiment operation principle is as follows:
When in the process of uncapping, when angle of uncapping reaches certain limit, eccentric wheel 3 long end can by pressure microswitch SW, microswitch SW in figure is closed, at this moment L line is linked into power subsystem exactly, power subsystem is started working, and export vdd voltage to MCU chip, MCU chip detects that namely vdd voltage starts normal work.By prior setting, after MCU chip detects that vdd voltage is started working, relay R L pickup signal will be sent, allow the adhesive of relay R L contact, at this moment power subsystem normally works, and now namely achieves start, if other push button signallings do not detected in certain hour after start, then washing machine cuts out display automatically, and relay R L control signal cancels output subsequently, and relay R L disconnects.After angle of uncapping reaches certain limit, microswitch SW disconnects, but now relay R L adhesive, control panel still can keep normal work.
When in the lid process of pass, when closing lid angle and reaching certain limit, eccentric wheel 3 structure can by pressure microswitch SW, microswitch SW in figure is closed, at this moment L line is linked into power subsystem exactly, power subsystem is started working, and export vdd voltage to MCU chip and relay R L, MCU chip detects that namely vdd voltage starts normal work.By prior setting, after MCU chip detects that vdd voltage is started working, relay R L pickup signal will be sent, allow the adhesive of relay R L contact, at this moment power subsystem normally works, and after door for washing machine covers completely, microswitch SW disconnects, but now relay R L adhesive, control panel still can keep normal work.After working procedure terminates, relay R L disconnects, control panel power-off.When after the lid of pass, without operation in certain hour, then washing machine can automatic shutdown, and auto-breaking after shutdown.
The present embodiment is provided with eccentric wheel 3 due to door for washing machine rotating shaft place, under the operating knob arranging microswitch SW only can be pressed in the rotation process of uncapping and close lid, and after completing and uncapping or close lid action, microswitch SW is all in the state of disconnection, uncap after closing lid action if so just achieved, washing machine is controlled to power on or power-off by MCU chip completely, when after program end of run, relay R L is controlled to disconnect, and now microswitch SW is also in off-state, so just achieve the door-opening electrification function of washing machine.The farthest that make use of eccentric wheel 3 is pressed into the operating knob of microswitch SW, and closes the operating knob covering afterwards and all can not be pressed into after uncapping microswitch SW normally.
It should be noted last that, above detailed description of the invention is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
