Abstract
The utility model provides a washing machine automatic door lock. The washing machine automatic door lock comprises a rotating type piezoelectric motor. The piezoelectric motor comprises a stator and a rotor. Internal threads are arranged on the internal side wall of the rotor. The matched rotor is provided with a lock tongue. External threads matched with the internal threads of the rotor are arranged on the outer wall of the lock tongue. An inductive switch is arranged on one side of the stator, and an induction end of the inductive switch is arranged on the port of the stator. The piezoelectric motor is adopted as a power source. The rotor of the piezoelectric motor is used as a lock cylinder of the washing machine automatic door lock at the same time. A vibrating part inside the stator is used for driving the rotor to move in a rotating mode along the forward direction and the reverse direction, and therefore screwing-in or screwing-out between the rotor and the lock tongue can be achieved, and the purpose of opening or locking a washing machine cover can be achieved. The washing machine automatic door lock is simple in structure and strong in external force interference resistance, and can achieve automatic safe locking or opening of the washing machine cover fast.
Description
Technical field
The utility model relates to the washing machine technical field, is specifically related to a kind of washing machine automatic door lock.
Background technology
Existing in the market washing machine all is automatic washing machines of being controlled by master control borad, and it adopts centrifugal dehydration mostly, and its rotating speed height, rotary inertia are big, therefore suitable cover door lock need be set, to guarantee the security in the machine operation procedure.Prevent that in washing process cover can be opened and cause water and clothing in the washing machine to be run out on the one hand in inner tank of washing machine; When preventing high speed dewatering on the other hand clothing is thrown away, or human body contacts the danger of rotating interior bucket and causing.
At present, the cover door lock of washing machine mainly is an automatic door lock device, and it mainly is made of electromagnet or bimetal leaf, slide block, bolt etc.But, and mainly be to rely on slide rail to position the reliability deficiency because the volume of electromagnet type door lock is bigger; And the double-metal sheet type door lock retardance of having opened the door can not realize quick closure or openness, and belong to the power consumption type, and promptly the double-metal sheet type door lock will continue power consumption in the course of the work, then automatically terminates locking after the abnormal power-down.The complex structure of these two kinds of automatic door lock devices, the problem that destabilizing factor is more is existing deficiency aspect security and the reliability.
The utility model content
In order to overcome deficiency of the prior art, the invention provides a kind of simple in structure, reliability and safe washing machine electronics automatic door lock, this door lock can not only be realized the washing machine hood of duty is carried out locking fast and safely, and can realize that soft-touch type opens the door automatically.
In order to reach above-mentioned effect, the utility model provides a kind of washing machine automatic door lock, comprise rotary piezo-electric motor, described piezo-electric motor comprises stator and rotor, the madial wall of described rotor is provided with internal thread, the arrival end of respective rotor is provided with dead bolt, and described dead bolt outer wall is provided with the external screw thread that matches with the rotor internal thread; One side of described stator is provided with inductive switch, and the induction end of inductive switch is positioned at the port of stator.
Described piezo-electric motor is fixedly arranged in the middle of the housing of being made up of loam cake and lower cover, and described inductive switch is fixedlyed connected with lower cover.
Described piezo-electric motor all is electrically connected with the master control borad of washing machine with inductive switch.
Wherein piezo-electric motor also claims rotary piezoelectric motors or supersonic motor, is made up of stator and rotor, and stator interior is provided with exciting spare, drives the rotate-stationary mode that rotor carries out positive and negative direction.Inductive switch all is electrically connected with the master control borad of washing machine with piezo-electric motor.
The rotor of the piezo-electric motor in the utility model is equivalent to lock core, and itself and dead bolt reach locking and the purpose of opening by screw-threaded coupling.Dead bolt is installed on the cover of washing machine, and the housing of being made up of loam cake and lower cover is installed on the casing of washing machine, fixes by loam cake, the screw hole that covers down.
When closing the cover of washing machine, when dead bolt inserted the rotor port, inductive switch was sensed dead bolt, sent signal and connected the circuit of piezo-electric motor, carried out positive direction after the piezo-electric motor energising and rotated and screw in dead bolt; When dead bolt put in place, inductive switch sent signal, made the down circuitry of piezo-electric motor, thereby had closed piezo-electric motor, promptly cover and casing of washing machine was locked.
When opening washing machine hood, can be divided into two kinds of situations: a kind of is that the washing machine control panel sends enabling signal after program for washing finishes, and master control borad control piezo-electric motor reverses, and lock core screws out dead bolt, has promptly opened the cover of washing machine.Second kind of situation is that the people is the door opening key of pressing in the washer operation panel, the counter-rotating of master control borad control piezo-electric motor, and lock core screws out dead bolt, has promptly opened the cover of washing machine.
The utility model adopts piezo-electric motor as power source, the rotor while of piezo-electric motor is as the lock core of this automatic door lock, vibrating member by stator interior drives the rotate-stationary mode that rotor carries out positive and negative direction, realize precession or back-out between rotor and the dead bolt, reach the purpose that opens or closes of washing machine hood.
In addition, because piezo-electric motor has characteristics such as low speed high torque, holding torque is big, size is little, efficient is high, the life-span is long, so have great advantage compared to the door lock tool of other solenoid actuated.And bigger driving torque and holding torque, it is strong to make this automatic door lock external force resistance disturb.
The utility model is simple in structure, reliability and security is high, can realize fast washing machine hood automatically, safety locking or open.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation;
Among the figure: 1-loam cake, 2-lower cover, 3-dead bolt, 4-rotor, 5-stator, 6-inductive switch.
The specific embodiment
As shown in Figure 1, a kind of washing machine automatic door lock comprises rotary piezo-electric motor, and piezo-electric motor is fixedly arranged in the middle of the housing of being made up of loam cake 1 and lower cover 2; Described piezo-electric motor comprises stator 5 and rotor 4, and the madial wall of described rotor 4 is provided with internal thread, and supporting rotor is provided with dead bolt 3, and described dead bolt 3 outer walls are provided with the external screw thread that matches with rotor 4 internal threads; One side of described stator 5 is provided with inductive switch 6, and inductive switch 6 is fixedlyed connected with lower cover 2, and the induction end of inductive switch 6 is positioned at the port of stator 5; Described piezo-electric motor all is electrically connected with the master control borad of washing machine with inductive switch 6.
The utility model adopts piezo-electric motor as power source, the rotor while of piezo-electric motor is as the lock core of this automatic door lock, vibrating member by stator interior drives the rotate-stationary mode that rotor carries out positive and negative direction, realize precession or back-out between rotor and the dead bolt, reach the purpose that opens or closes of washing machine hood.
