Detailed description of the invention
Below in conjunction with the accompanying drawing in the present embodiment, carry out specifically, clearly and completely describing to the technical scheme in embodiment.
A kind of automatic control drainage device disclosed by the invention, comprise water-drainage tube part 1, seal 2, direct current generator 3, worm screw 4, worm gear 5, screw mandrel 6 and the first shell 7, the cephalic par of described screw mandrel 6 is fixedly connected with seal 2, described seal 2 is disposed adjacent with water-drainage tube part 1, described direct current generator 3 drives with worm screw 4 and is connected, described worm screw 4 is meshed with worm gear 5, described worm gear 5 is in transmission connection with screw mandrel 6, make screw mandrel 6 reciprocating by a rotation preventive mechanism, band dynamic seal 2 moves together, make between seal 2 and water-drainage tube part 1 in be tightly connected or tool at regular intervals, thus realize sealing or draining.
Refer to shown in Fig. 1-2 and Fig. 4-7, in one embodiment of the present invention, described rotation preventive mechanism comprises the coupling blocking surface 61 being arranged at screw mandrel 6 two ends respectively that the relative spline platform 50 of two of being arranged on worm gear 5 coordinates with described spline platform 50 with section, mates blocking pin 62, and on described screw mandrel 6, also correspondence offers spline groove 63.The outer surface of described screw mandrel 6 is provided with helicla flute 64, and the side of described helicla flute 64 comprises opens face 64a and locking face 64b, and the angle of described locking face 64b is greater than the angle opening face 64a.Concrete, described in open face angle be 90 °, the angle of described locking face is greater than 90 °.In helicla flute, two sides use asymmetric design, and locking face angle is large and open face angle, after can effectively preventing screw thread from screwing, then the problem of just revolving not open of reversing.
When screw mandrel 6 moves to one end, as seal 2 compress time, spline platform corresponding thereto coupling blocking surface contact, stop screw mandrel 6 continue motion, bear whole torsion simultaneously, prevent two helicla flutes locked because of coupling mechanism force, revolve not open when preventing pivotal; When screw mandrel 6 moves to the other end time, act on identical.
Described direct current generator 3 is connected with a controlling organization, and controlling organization detects the electric current of direct current generator inside, controls the rotating of direct current generator.The outside of described direct current generator 3 is also provided with a second housing 30.The side, front of described worm gear is also provided with screw mandrel location working of plastics 9.
When needs seal time, the controlling organization of washing machine is powered to direct current generator 3 forward, direct current generator 3 rotates forward, worm screw 4 is driven to drive worm gear 5 to rotate, worm gear 5 drives screw mandrel 6 to move, screw mandrel 6 is with dynamic seal 2 to travel forward again, water-drainage tube part 1 compresses by seal 2, realize sealing, the coupling blocking surface now on screw mandrel 6 contacts with the spline platform 50 on worm gear 5, and screw mandrel stops operating, direct current generator also can stall, controlling organization can detect that the electric current in direct current generator obviously increases, and cuts off power supply at once, completes a sealing action.
When needs draining, the controlling organization of washing machine is oppositely powered to direct current generator 3, direct current generator 3 reverses, worm screw 4 is driven to drive worm gear 5 to rotate, worm gear 5 drives screw mandrel 6 again, and screw mandrel 6 is with dynamic seal 2 to move backward, pulls open seal 2, seal and water-drainage tube part 1 are departed from and has certain spacing, thus realize drain function.Now the coupling blocking pin 62 of screw mandrel 6 contacts with another spline platform 50 on worm gear 5, and screw mandrel 6 stops operating, and direct current generator also can stall, and controlling organization can detect that the electric current in direct current generator obviously increases, and cuts off power supply at once, completes another draining action.
Direct current generator has rotating two kinds of type of drive, and by the rotating of above direct current generator, when forward drive, motor rotates forward, and makes screw mandrel press seal part, plays sealing function, the motor reversal when reverse drive, screw mandrel is retreated, pulls open seal, water is drained.So, realize sealing and the perseveration pulled open, reach the requirement of drainer for washer.
The present invention's direct current generator replaces alternating current generator, the voltage between 3V ~ 24V can, security significantly improves, and also strengthen fire-proof and water-proof requirement without the need to doing, safe and reliable, cost is lower.
Shown in Figure 3, be another preferred embodiment of the present invention, the limit method that screw mandrel moves to two ends is different.Described rotation preventive mechanism comprises the first limit switch 81, second limit switch 82 and the spacing catch 83 be arranged on the first shell, and described spacing catch 83 is fixedly installed on screw mandrel 6 by a screw 84, is linked to be an entirety.
When screw mandrel 6 moves to seal 2 by water-drainage tube part 1 press seal one end time, spacing catch 83 contacts the first limit switch 81, controlling organization directly disconnects the power supply of direct current generator, or controlling organization activation signal given by the first limit switch 81, disconnected the power supply of direct current generator again by it, realize a sealing action.
When screw mandrel 6 moves to seal 2 and water-drainage tube part 1 departs from one end, spacing catch 83 contacts with the second limit switch 82, same principle, direct current generator power-off, realizes a sealing action.The screw mandrel of the present embodiment moves to two ends and adopts limit switch to direct current generator power-off, thus realizes reciprocating motion.
In sum, the present invention does not have complicated gear to add the combined speed reducer structure of connecting rod, one group of worm and gear is only had to add the reducing gear of screw mandrel, simple and reliable for structure, the little torque of direct current generator, slowed down by worm and gear, pass through screw rod transmission again, larger axially-movable power is obtained after making the torque of direct current generator convert rectilinear motion to, be amplified to larger thrust, effectively can ensure the sealing of sealing ring, (prior art sealing load only has 1.5 ~ 2.5 kilograms to avoid the seepy question that occurs because pressure is too small, the present invention can be easy to the sealing load reaching 10 ~ 20 kilograms), effectively can reduce production process, and reduce production cost.
Above-mentioned detailed description of the invention is a better embodiment, and be only and technical conceive of the present invention and design feature are described, object is person skilled in the art can be implemented according to this, does not limit the scope of the invention with this.Every any equivalence done according to Spirit Essence of the present invention changes or modifies, and all should be encompassed in protection scope of the present invention.
