Description
Technical field
The present invention relates to electrical accessorie technical field, especially relate to a kind of washing machine waterproof machine.
Background technique
The motor used in household electrical appliances paddled by washing machine etc., needs to carry out water-proofing treating mostly.Such as, at the sheathed stuffing box gland of this outside motor.But, after adopting which, comparatively be difficult to resolve at the connection part of line shaft of sealing cover and motor and certainly leak water problem, and this connection part mostly is through hole and line shaft adopts transition fit, thus after line shaft High Rotation Speed, through-hole inner surface wearing and tearing are comparatively serious, temperature is higher and cannot dispel the heat, and working life is shorter then, also has the hidden danger of spontaneous combustion.
Summary of the invention
The object of this invention is to provide a kind of washing machine waterproof machine, it is longer, safer that it has working life, and the good feature of sealing effect.
The technical solution adopted in the present invention is: washing machine waterproof machine, comprise the body of the motor be fixed in this washing machine, this body has the line shaft upwards extended, through the base plate of the laundry room of this washing machine after this line shaft upwards extends, and this line shaft is arranged with a seal ring, sealing circle is fixed on this base plate, described body exterior is arranged with a waterproof jacket, this waterproof jacket top has one for the through hole passed of this line shaft Spielpassung, simultaneously, this line shaft is positioned at the top of this through hole, the below of this base plate is provided with a step, the upper surface of this step is provided with the water dumping groove of at least 3 line stretchers by this line shaft, and, this through hole has the lower convex edge of the annular upwards extended, the lower surface of this lower convex edge and this step matches, and, a stage clip is provided with between the bottom of this waterproof jacket and the bottom of this washing machine, the bottom of this base plate is fixed with an oil hydraulic cylinder, the telescopic end of this oil hydraulic cylinder connects this waterproof jacket, and the switch gearing of this oil hydraulic cylinder is in the switch of this body.
The outer rim of the downside of described step is provided with one to the upper convex edge of the annular of downward-extension, and on this, the internal diameter of convex edge is greater than the external diameter of this lower convex edge.
The present invention is advantageously: working life is longer, safer, and sealing effect is better.The outside of the motor body of washing machine waterproof machine of the present invention is provided with waterproof jacket, and this waterproof jacket is used for the through hole that passes of this line shaft and this line shaft is Spielpassung, then the internal surface of this through hole there will not be serious wear, and the higher and phenomenon that cannot dispel the heat of temperature, and then this waterproof machine is made to have longer working life and safer.Meanwhile, under the connecting part of this line shaft and this base plate has the prerequisite of seal ring, after this machine operation, even if there is part to leak in laundry room downwards, these leak and also cannot cross the step that this line shaft has, thus can not impact motor.

Embodiment
Embodiment, is shown in shown in Fig. 1 to Fig. 4: washing machine waterproof machine, comprises the body 10 of the motor be fixed in this washing machine 100.This body 10 has the line shaft 11 upwards extended.This line shaft 11 upwards extends the rear base plate 102 of laundry room 101 through this washing machine 100 thus the upper end of this line shaft 11 is positioned at this laundry room 101.This line shaft 11 is arranged with a seal ring 20, sealing circle 20 is fixed on this base plate 102.Obviously, sealing circle 20 is positioned at the connecting part of this line shaft 11 and this base plate 102.
More specifically, this body 10 outer cover is provided with a waterproof jacket 30, and this waterproof jacket 30 can lower openings.This waterproof jacket 30 top has one for the through hole 31 passed of this line shaft 11 Spielpassung.Meanwhile, this line shaft 11 is positioned at the top of this through hole 31 and the below being positioned at this base plate 102 is provided with a step 12.The upper surface of this step 12 is provided with the water dumping groove 121 of at least 3 line stretchers by this line shaft 11.Certainly, this water dumping groove 121 can be that straight line type also can be curvilinerar figure.And this through hole 31 has the lower convex edge 311 of the annular upwards extended.The lower surface of this lower convex edge 311 and this step 12 matches.That is, this lower convex edge 311 can contact the lower surface of this step 12 closely.And, be provided with a stage clip 40 between the bottom of this waterproof jacket 30 and the bottom of this washing machine 100.That is, this stage clip 40 makes this waterproof jacket 30 have one to the trend of top offset.The bottom of this base plate 102 is fixed with an oil hydraulic cylinder 50, and the telescopic end of this oil hydraulic cylinder 50 connects this waterproof jacket 30, and the switch gearing of this oil hydraulic cylinder 50 is in the switch of this body 10.Obviously, the switch of this oil hydraulic cylinder 50 can be solenoid valve, and the switch of this body 10 can be the power switch of suction type.So-called two switch gearings, refer to the switch of this body 10 closed after, the telescopic end of the switch opens of this oil hydraulic cylinder 50 this oil hydraulic cylinder 50 then can promote this waterproof jacket 30 downwards.
Further say, the outer rim of the downside of this step 12 is provided with one to the upper convex edge 122 of the annular of downward-extension, and on this, the internal diameter of convex edge 122 is greater than the external diameter of this lower convex edge 311.That is, see to project downwards, on this, convex edge 122 is enclosed within the outside of this lower convex edge 311.Like this, the water flowed down from this step 12 can not drop in this through hole 31, thus can not form impact to this body 10.
Working principle of the present invention: 1, as shown in Figure 1, when this washing machine waterproof machine does not carry out work, this waterproof jacket 30 is under the effect of this spring 40, and this lower convex edge 311 holds out against on the lower surface of this step 12, concrete, withstand on the inside of the upper convex edge 122 of this step 12.Like this, leak even if having in this laundry room 101, then leak and also can not be entered in this waterproof jacket 30 by this through hole 31, thus motor can not be made to suffer damage.2, as shown in Figure 2, when this washing machine waterproof machine works, this oil hydraulic cylinder 50 works, and then pushes this waterproof jacket 30 to bottom offset.Now, although this lower convex edge 311 no longer holds out against the lower surface of this step 12, even if but having part to leak in this laundry room 101 moves down along this line shaft 11, after then these water arrive the upper surface of this step 12, under the influence of centrifugal force, these water can throw away along this water dumping groove 121, finally still can not cross this step 12.
Certainly, this waterproof jacket 30 can slide be arranged at multiple vertical setting slide bar on, thus be more beneficial to the upper and lower displacement of this waterproof jacket 30.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
