The upper controller for electric consumption of described automatic washing machine, described first switch element selects single-pole double throw microswitch, described second switch element selection single-pole double throw magnetic latching relay, described 3rd switch element selection normally opened relay；Two of described single-pole double throw microswitch not moved end connects one to one with two stationary contacts of single-pole double throw magnetic latching relay.
As shown from the above technical solution, the present invention, by arranging electrification circuit, makes user by opening door of washing machine cover plate or closing door of washing machine cover plate, can realize powering on washing machine controller, eliminating power button, control panel is more attractive in appearance, and washing machine controller is in the standby state simultaneously, automatically process, power cutoff, makes complete machine power-off, with less cost, achieve the function of hommization, save the energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of the invention；
Fig. 2 is the electrification circuit schematic diagram of the specific embodiment of the invention.
Detailed description of the invention
The present invention is further illustrated below in conjunction with the accompanying drawings with specific embodiment.
As shown in Figure 1, a kind of upper controller for electric consumption of automatic washing machine, including door of washing machine cover plate 2, electrification circuit 3, the power-switching circuit 4 of washing machine controller, main control chip 5 and control circuit 6, electrification circuit 3 is arranged on the live wire between power-switching circuit 4 and forceful electric power plug 1.Electrification circuit 3 includes the first switch element 31, second switch element 32 and the 3rd switch element 33, and the first switch element 31 is in parallel with the 3rd switch element 33 again after connecting with second switch element 32.First switch element 31 links with door of washing machine cover plate 2, and the outfan of power-switching circuit 4 is connected with the input of main control chip 5, and the outfan of main control chip 5 passes through the control circuit 6 input respectively with second switch element 32 and the 3rd switch element 33 and is connected.
As in figure 2 it is shown, the first switch element 31 selects single-pole double throw microswitch, linking with door of washing machine cover plate 2, when door of washing machine cover plate 2 is opened or closed, the first switch element 31 is in the position of a or b.Single-pole double throw magnetic latching relay selected by second switch element 32, is characterized in control its location by energising, and when without electricity, its position can keep constant.3rd switch element 33 selects normally opened relay, is characterized in energising conducting, disconnects under electroless state.The state of the first switch element 31 is controlled by washing machine controller by the action control of door of washing machine cover plate 2, the state of second switch element 32 and the 3rd switch element 33 under having electricity condition.
The operation principle of the present invention:
Under original state, assume that now door of washing machine cover plate 2 is closed, first switch element 31 is in position a, second switch element 32 is in position b, and the loop residing for the i.e. first switch element 31 and second switch element 32 is off, and the 3rd switch element 33 is also at off-state without electricity, therefore, electrification circuit 3 is off, it is impossible to civil power is introduced the power-switching circuit 4 of washing machine controller by plug 1, and washing machine controller is without electricity.
Open door of washing machine cover plate 2, first switch element 31 is owing to linking with door of washing machine cover plate 2, it is in position b, now second switch element 32 is still in position b, 3rd switch element 33 is still off, the loop conducting residing for upper midway that is first switch element 31 of electrification circuit 3 and second switch element 32, and civil power is changed by power-switching circuit 4, powering for main control chip 5, main control chip 5 is started working.After main control chip 5 is started working, controlling the 3rd switch element 33 and close, now the two-way of electrification circuit 3 all turns on.
Turning off door of washing machine cover plate 2, then the first switch element 31 action, be in position a, the upper midway of electrification circuit 3 disconnects, and only lower conducting on the way, the only Guan Bi by the 3rd switch element 33 keeps the "on" position of washing machine controller.After main control chip 5 is in holding state, when deenergization, only need to be disconnected by the 3rd switch element 33, afterwards, electrification circuit 3 is fully disconnected, and washing machine controller is fully powered-off.
From the above, the present invention utilizes the use characteristic of washing machine, it is switched on door cover plate 2 before i.e. using and puts clothes into washing machine, then door cover plate 2 is shut and wash again, by special electrification circuit 3, coordinate and control logic accordingly, it is achieved washing machine controller, by opening door cover plate 2 or closing the action of door cover plate 2, can be powered on by user；When holding state, whether main control chip 5 first detects the upper midway of electrification circuit 3 still in conducting state, if, then by controlling the state of second switch element 32, the upper midway making electrification circuit 3 disconnects, and then, then disconnects the 3rd switch element 33, i.e. achieving the fully powered-off of washing machine controller, the stand-by power consumption making washing machine controller is zero.
The above embodiment is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present invention determines.
