Description

The electromagnetic door lock of use in washing machine
Technical field
The utility model relates to the door interlock switch of a kind of door lock open and close device of the locking and unlocking, particularly use in washing machine.
Background technology
The positive side of the roller washing machine matrix that button opens the door is provided with an opening portion, is used for to cylinder input/taking-up washings, and described opening portion is closed by the gate that opens and closes freely.Use button to open the washing machine of gate, which is provided with door open button, when the clamshell doors button applies pressing operation, be delivered to the door-opening mechanism of door interlock switch by drag hook, door-opening mechanism affacts the mechanism of closing the door that links with it, the mechanism of closing the door is rotated or moves, thereby gate is opened.
On the door interlock switch that present button opens the door, the protection mechanism that opens the door is not set.When the power on the drag hook is excessive, can damage door interlock switch.To this problem, part washing machine manufacturer has increased the stroke design in the design of button.But because the door interlock switch required precision is higher, and the washing machine fit tolerance of opening the door between drag hook and button and the door interlock switch is bigger, can be opened in order to ensure the energy gate, and stroke need be set than opening the door needed stroke more greatly.Bad to the effect of door lock protection like this.Also have the part washing machine to be provided with spring etc. between button and door lock pull bar and meet absorbing mechanism, for example, utility model patent number is 200420014189.1 washing machine utility model patent.Use the drag hook spring to substitute the drag hook that opens the door, when active force is too big, can sponge, but increased cost by spring.
Summary of the invention
In view of the above problems, the purpose of this utility model be to provide a kind of its inside contain the protection mechanism that opens the door, protection also can be provided when washing machine button stroke is excessive and not increase the electromagnetic door lock of the use in washing machine of washing machine cost.
For reaching above-mentioned purpose, the electromagnetic door lock of use in washing machine of the present utility model comprises as an embodiment: matrix (1) and join loam cake (2), a dog hole (200) that inserts for gate stop when loam cake (2) is provided with and closes, matrix (1) is provided with electromagnet (6), its front end is associated with iron core (5), iron core (5) links with operation panel (4), operation panel (4) is provided with location/reseting groove platform structure (400) and projection (401), be provided with back-moving spring (12) between operation panel and the matrix, also be provided with the slide lock body on the matrix, effect one back-moving spring (13) on it, the slide lock body is provided with projection 300, and upward projection (401) is corresponding with operation panel (4), and has by groove structure, links with the pull bar that opens the door (7), open the door and establish a block (702) on the pull bar, and on matrix, establish corresponding muscle (101).
In the electromagnetic door lock of this use in washing machine, original state, the washing machine drag hook affacts on the door interlock switch pull bar (7), and the pull bar that opens the door (7) can freely spur.Slide lock body (3) in door interlock switch, the position when drawing back door and opening fully, the protection mechanism that opens the door begins to work, and stops pull bar to be continued pulling, prevents that door interlock switch from being destroyed by excessive pulling force.At this, the protection mechanism that opens the door is by set block (701) on the pull bar that opens the door, and establishes on the matrix that muscle (101) forms.Muscle on the matrix links to each other with sidewall with the matrix bottom.After gate was opened fully, block (701) was run on the matrix muscle (101), made door-opening mechanism afford excessive power and passed through block, be delivered on the muscle, be distributed to again on matrix bottom and the wall, prevent on the matrix of door lock in the past that the somewhere stress occurs and too concentrates and realize the defencive function thereby realization is opened the door; Loam cake also can increase muscle on (2), and the power that the pull bar that further disperses to open the door is subjected to strengthens protective effect.
The protection mechanism that opens the door all is to increase features such as block, muscle on other functional part by door lock, does not need to increase parts and new mould, so can not produce bigger cost.
