Abstract
The utility model relates to a direct-current driving door locking device for a washing machine, which comprises a lock cylinder, a cam and a coil, wherein the cam is matched with the lock cylinder; the cam has a long end and a short end, and the long end is butted on the lock cylinder and is matched with the lock cylinder; and the coil is close to the lock cylinder. The direct-current driving door locking device for the washing machine has a simple structure and simple control and can effectively reduce the cost, and a door lock can be minimized.
Description
Technical field
The utility model relates to a kind of door lock assembly, especially a kind of use in washing machine DC driven door lock assembly.
Background technology
Door interlock switch in the existing washing machine be mostly through control relay conducting whether, control the folding of door lock, use that the door lock of this scheme has that volume is big, complex structure and the complicated defective of control method.
So, need a kind of new technical scheme to address the above problem.
The utility model content
The purpose of the utility model is the deficiency that exists to prior art, and a kind of use in washing machine DC driven door lock assembly simple in structure is provided.
For realizing the foregoing invention purpose, the utility model use in washing machine DC driven door lock assembly can adopt following technical scheme:
A kind of use in washing machine DC driven door lock assembly comprises lock core, the cam that cooperates with lock core and coil, and said cam has long end and short end, and said long end is resisted against on the lock core and with lock core and cooperates, and said coil is near lock core.
Compare with background technology, the utility model use in washing machine DC driven door lock assembly is simple in structure and control is simple, can effectively reduce cost and makes the door lock miniaturization.
Description of drawings
Fig. 1 is the structural scheme of mechanism of the utility model use in washing machine DC driven door lock assembly.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment; Further illustrate the utility model; Should understand these embodiments only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
See also shown in Figure 1ly, the utility model discloses a kind of use in washing machine DC driven door lock assembly 100, the cam 30 that comprises lock core 20, cooperates with lock core 20, coil 40, the switch 50 that contacts with lock core 20 and the control chip (not shown) that is connected with switch 50.Said cam 30 has long end 31 and short end 32, and said long end 31 is resisted against on the lock core 20 and with lock core 20 and cooperates, and shortly holds 32 not contact all the time with lock core 20.Said coil 40 is near lock core 20.In use; Coil 40 logical direct currents are produced magnetic force, thus coil 40 adhesive cams 30, and cam 30 is when rotating; Long end 31 is pushing away lock core 20 forward; Lock core 20 withstands switch 50 when advancing, the door lock of washing machine (not shown) is closed, and switch 50 close feedback signal to chip " door close ".After coil 40 outage, cam 30 is fixing, and lock core 20 is withstood by the long end 31 of cam 30 and can't return and be in stationary state equally, and this moment, the door lock of washing machine was in closed condition.When the logical once more direct current of coil 40; Cam 30 is rotated further under the attraction of coil until long end 31 and lock core 20 and breaks away from; Lock core 20 broke away from the constraint of cam 30 and was returned to the home position and breaks away from switch 50 this moment; This moment washing machine door-lock opening, and switch 50 is opened and the feedback signal of giving chip " door is opened ".Coil 40 cuts off the power supply once more, door-lock opening.The utility model use in washing machine DC driven door lock assembly 100 is simple in structure and control is simple, can effectively reduce cost and makes the door lock miniaturization.
Claims (3)
1. use in washing machine DC driven door lock assembly is characterized in that: comprise lock core, the cam that cooperates with lock core and coil, said cam has long end and short end, and said long end is resisted against on the lock core and with lock core and cooperates, and said coil is near lock core.
2. use in washing machine DC driven door lock assembly as claimed in claim 1 is characterized in that: this use in washing machine DC driven door lock assembly also includes and the switch of lock core contact and the control chip that is connected with switch.
