Detailed description of the invention
Below in conjunction with the accompanying drawing in the present embodiment, the technical scheme in embodiment is had
Body, clearly and completely describe.
A kind of automatic control drainage device disclosed in this utility model, including water-drainage tube part 1, close
Sealing 2, direct current generator 3, worm screw 4, worm gear 5, screw mandrel 6 and the first shell 7, described silk
The cephalic par of bar 6 is fixing with sealing member 2 to be connected, and described sealing member 2 is adjacent with water-drainage tube part 1
Arranging, described direct current generator 3 and worm screw 4 drive connection, described worm screw 4 nibbles with worm gear 5 phase
Closing, described worm gear 5 is in transmission connection with screw mandrel 6, makes screw mandrel 6 make back and forth by a rotation preventive mechanism
Motion, band dynamic seal 2 moves together, makes between sealing member 2 and water-drainage tube part 1 in sealing
Connect or have at regular intervals, thus realizing sealing or draining.
Refer to shown in Fig. 1-2 and Fig. 4-7, in this utility model one preferred embodiment, described
Rotation preventive mechanism includes two be arranged on worm gear 5 relative spline platforms 50 and with described
The coupling blocking surface 61 being respectively arranged at screw mandrel 6 two ends, coupling that spline platform 50 coordinates hinder
Backing pin 62, on described screw mandrel 6, also correspondence offers spline groove 63.The appearance of described screw mandrel 6
Face is provided with helicla flute 64, and the side of described helicla flute 64 includes opening face 64a and locking face
64b, the angle of described locking face 64b is more than the angle opening face 64a.Concrete, described
The angle opening face is 90 °, and the angle of described locking face is more than 90 °.Both sides in helicla flute
Face uses asymmetric design, and locking face angle is big and opens face angle, can effectively prevent screw thread from revolving
After Jin, then the problem that reversion is just revolved not open.
When screw mandrel 6 moves to one end, when compressing such as sealing member 2, spline platform is corresponding thereto
Coupling blocking surface contact, stop screw mandrel 6 continue motion, bear whole torsion simultaneously, prevent
Two helicla flutes are locked because of coupling mechanism force, prevent from revolving not open the when of revolution；When screw mandrel 6 moves
The when of to the other end, act on identical.
Described direct current generator 3 is connected with a controlling organization, inside controlling organization detection direct current generator
Electric current, control direct current generator rotating.The outside of described direct current generator 3 is additionally provided with one
Second housing 30.The side, front of described worm gear is additionally provided with screw mandrel location working of plastics 9.
When needs seal when, the controlling organization of washing machine is powered to direct current generator 3 forward,
Direct current generator 3 rotates forward, and drives worm screw 4 to drive worm gear 5 to rotate, and worm gear 5 drives screw mandrel 6 to move
Dynamic, screw mandrel 6 band dynamic seal 2 again travels forward, and water-drainage tube part 1 is compressed by sealing member 2,
Realize sealing, now the coupling blocking surface on screw mandrel 6 and the spline platform 50 on worm gear 5
Contact, screw mandrel stops operating, direct current generator also can stall, controlling organization can detect unidirectional current
Electric current in machine significantly increases, and cuts off power supply at once, completes a sealing action.
When needs draining, the controlling organization of washing machine is to direct current generator 3 reverse power supply, direct current
Motor 3 inverts, and drives worm screw 4 to drive worm gear 5 to rotate, and worm gear 5 drives screw mandrel 6, silk again
Bar 6 band dynamic seal 2 rearward movement, pulls open sealing member 2, makes sealing member and water-drainage tube part 1
Depart from and have certain spacing, thus realize drain function.The now coupling blocking pin of screw mandrel 6
62 contact with another spline platform 50 on worm gear 5, and screw mandrel 6 stops operating, direct current generator
Also can stall, controlling organization can detect that the electric current in direct current generator significantly increases, and cuts off at once
Power supply, completes another draining action.
Direct current generator has two kinds of type of drive of rotating, by the rotating of above direct current generator,
When forward drive, motor rotates forward, and makes screw mandrel compress sealing member, plays sealing function, when reversely
Motor reversal during driving, makes screw mandrel retreat, pulls open sealing member, makes water drain.So, it is achieved
The perseveration sealed and pull open, reaches the requirement of drainer for washer.
This utility model direct current generator replaces alternating current generator, and the voltage between 3V～24V is all
Of course, safety significantly improves, without doing reinforcement fire-proof and water-proof requirement, safe and reliable, becomes
This is lower.
Shown in Figure 3, for another preferred embodiment of the present utility model, screw mandrel moves to two
The limit method of end is different.Described rotation preventive mechanism includes that be arranged on the first shell first is spacing
Switch the 81, second limit switch 82 and spacing catch 83, described spacing catch 83 passes through
One screw 84 is fixedly installed on screw mandrel 6, is linked to be an entirety.
When screw mandrel 6 move to sealing member 2 water-drainage tube part 1 is compressed sealing one end when, limit
Position catch 83 contacts the first limit switch 81, and controlling organization directly disconnects the power supply of direct current generator,
Or one activation signal of controlling organization given by the first limit switch 81, then disconnects direct current by it
The power supply of motor, it is achieved a sealing action.
When screw mandrel 6 moves to sealing member 2 and water-drainage tube part 1 departs from one end, spacing catch
83 contact with the second limit switch 82, same principle, direct current generator power-off, it is achieved one close
Envelope action.The screw mandrel of the present embodiment move to two ends use limit switch to direct current generator power-off,
Thus realize moving back and forth.
In sum, this utility model does not has the gear of complexity to add the combined speed reducer structure of connecting rod,
Only one group worm and gear adds the reducing gear of screw mandrel, simple and reliable for structure, direct current generator
Little torque, is slowed down by worm and gear, then by screw rod transmission, makes the torque of direct current generator turn
Obtain bigger axially-movable power after changing linear motion into, be amplified to bigger thrust,
Can effectively ensure that the sealing of sealing ring, it is to avoid the seepy question occurred because pressure is too small is (existing
Have technology seal pressure to only have 1.5～2.5 kilograms, this utility model can easily reach 10～
The seal pressure of 20 kilograms)；It is effectively reduced production process, and reduces production cost.
Above-mentioned detailed description of the invention is a better embodiment, and skill of the present utility model is only described
Art design and construction features, it is therefore intended that allow the person skilled in the art can be real according to this
Execute, do not limit protection domain of the present utility model with this.Every according to essence of the present utility model
Any equivalence that god's essence is done changes or modifies, and all should contain at protection model of the present utility model
In enclosing.
