Abstract
The utility model relates to a locking/unlocking electrical signal switching device of an electric door lock of a washing machine, belonging to the technical field of a control device of the electric door lock of the washing machine. The locking/unlocking electrical signal switching device comprises a gluey shell, a winding framework and a winding, wherein the gluey shell is used for bearing an electron component; the winding framework is arranged on the gluey shell; and the winding is supported by the winding framework and is electrically controlled by a controller. A spring and an iron core are arranged in the winding framework, and one end of the iron core extends out the winding framework to be connected with a self-locking block arranged on a track in the gluey shell. A peach-heart groove arranged in the bottom end face of the self-locking block is combined with elastic pieces in a matched mode, and the elastic pieces are arranged on the gluey shell and are connected in a penetrating manner through a shifting fork. A groove is arranged in the lower side of the self-locking block (5), and a pressing piece (1) outwards extending to the gluey shell for limiting the groove is arranged in the groove. One end of the pressing piece is movably contacted with a mobile elastic piece in a group of mobile and static elastic pieces (11 and 10) arranged on the gluey shell of a lock body. The structure is simplified, the reliability and the sensitivity of the locking/unlocking electrical signal switching of the electric door lock of the washing machine are increased, and the manufacture cost is also reduced.
Description
Technical field
The utility model relates to a kind of washing machine electric door lock lock/unlock signal of telecommunication switching device shifter, belongs to washing machine electric door lock control device technical field.
Background technology
Existing washing machine electric door lock lock/unlock signal of telecommunication switching device shifter; Comprise supporting, the fixing glue shell of electronic devices and components; By the coil of controller electric control, be arranged on the coil rack on the glue shell, be arranged on interior spring one end of coil rack and an end butt of iron core; Self-locking block on the other end of iron core stretches out coil rack and is arranged on glue shell inner orbit is connected; The self-locking block bottom face is provided with groove, cooperates with the shell fragment by the shift fork cross-under on being arranged on the glue shell, and the shake-up post of self-locking block one side setting contacts with the microswitch on being arranged on the glue shell is movable.But the switching of this dependence microswitch realizes that the washing machine electric door lock is locked or the signal of telecommunication switching device shifter of release, and reliability and sensitivity are relatively poor, and manufacturing cost is also higher.
The utility model content
The purpose of the utility model is to provide a kind of reliability and sensitivity is higher and manufacturing cost is lower washing machine electric door lock lock/unlock signal of telecommunication switching device shifter.
Its technical scheme is: a kind of washing machine electric door lock lock/unlock signal of telecommunication switching device shifter; Comprise supporting, the fixing glue shell of electronic devices and components; Be arranged on the coil rack on the glue shell and support and by the coil of controller electric control by coil rack; Be provided with spring and iron core in the coil rack; Self-locking block on one end of iron core stretches out coil rack and is arranged on glue shell inner orbit is connected, the peach heart groove that is provided with on the self-locking block bottom face be arranged on the glue shell on combine by the shell fragment of shift fork cross-under coupling, it is characterized in that: the downside of said self-locking block is provided with groove; Be provided with in this groove the limited impression that extends out on the glue shell by sincere, by a sincere end be arranged on the glue shell on one group of dynamic and static shell fragment in movable contact of spring plate.
Its beneficial effect is: adopt contact with self-locking block by sincere contact and the disengaging of controlling one group of dynamic and static shell fragment, both simplified the structure, improved the reliability and the sensitivity of washing machine electric door lock lock/unlock signal of telecommunication switching, reduced manufacturing cost again.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; A kind of washing machine electric door lock lock/unlock signal of telecommunication switching device shifter comprises supporting, the fixing glue shell 6 of electronic devices and components, is arranged on the coil rack 9 on the glue shell and is supported and by the coil of controller electric control by coil rack; Be provided with spring 8 and iron core in the coil rack; Self-locking block 5 on one end of iron core stretches out coil rack and is arranged on glue shell inner orbit is connected, and the self-locking block bottom face is provided with peach heart groove, be arranged on the glue shell on combine by the shell fragment of shift fork 3 cross-under 4 couplings.The downside of said self-locking block is provided with groove, be provided with in this groove the limited impression that extends out on the glue shell by sincere 1, by a sincere end be arranged on the glue shell on one group of dynamic and static shell fragment 11,10 in movable contact of spring plate.
For improving the sensitivity by sincere 1, the groove that the self-locking block downside is provided with is arc groove.
When washing machine controller sends when locking signal instruction to coil, coil electricity produces suction, moves right through iron core 7 pull-up self-locking blocks 5, and self-locking block drives shift forks 3 swings through shell fragment 4, realizes self-locking; Retreat under the thrust of spring plate 11 by sincere 1 simultaneously, make the contact contact on the dynamic and static shell fragment, lock signal and be delivered to washing machine controller in the generation, controller is promptly notified washing motor work; After washing was accomplished, controller sent unlocking signal to coil, and coil electricity produces suction; Through the iron core pull-up self-locking block a bit of distance that moves right, self-locking block drives shift forks 3 through shell fragment 4 and swings then, under the thrust that resets of spring 8; Self-locking block then be moved to the left moves forward downwards under the promotion of self-locking block 5 by sincere 1, pushes spring plate open and contacts with contact between the quiet shell fragment; The contact is broken off; Produce the release signal of telecommunication and be delivered to controller, controller provides the indication that can open the door, thereby realizes the switching of the washing machine electric door lock lock/unlock signal of telecommunication.
