Technical background
The water-saving sleeve washer of selling in the market that water is only arranged at interior bucket, by interior bucket is sealed, reduced the use amount of water, but the reliability of this washing machine is not high, main cause is that sealing surface is long, its movable sealing has partly adopted diameter to reach the big rotating seal ring of 80-100mm, linear velocity is up to 4-5m/s, static seal partly adopts the method for plastic heat sealing or special-shaped rubber gasket, sealing surface reaches 700-800mm, cause problems such as sealing is unreliable, production difficulty, life-span weak point, fault rate height, thereby fail to promote.
Summary of the invention
In order to overcome the problems referred to above, the purpose of this utility model provides a kind of water saving sleeve washer primary sealing surface hermetically-sealed construction, and its sealing is reliable, simple in structure.
The technical scheme that the utility model is dealt with problems is this kind water saving sleeve washer primary sealing surface hermetically-sealed construction, comprise sealing shroud, interior bucket, outer bucket, discharge structure, it is characterized in that described sealing shroud adopts the steps type seal cover, its top is big with the position diameter that interior bucket is connected with stopping-off piece, and the bottom is little with the position diameter that the water seal inboard is tightly connected mutually; Be provided with small sealing ring between steps type seal cover and the stopping-off piece; Water seal top is provided with and outer barrel of seal cover that is sealed and matched and is fixed on the outer bucket.
In order further discharge structure to be sealed, in the described discharge structure, adopt inner conduit, this inner conduit one end links to each other with hole sealing on the outer bucket, and the other end links to each other with a joint sealing, on joint and outer bucket seal and also fixedly connected outside barrel.The general employing of this seal cover is flat.
Be further to simplify technology, in the described discharge structure, adopt inner conduit, this inner conduit one end be arranged on the delivery port that is provided with on the seal cover and directly be tightly connected, the other end links to each other with a joint sealing, on joint and outer bucket sealing are also fixedlyed connected outside barrel.The general cylindrical interior volume formula of this seal cover.
This technical scheme reduces the movable sealing face of existing water-conservation washing machine, and adopting diameter only is the small-sized rotating seal ring of 38-40mm, and linear velocity is 2m/s only.Static seal partly adopts pressure plate structure and inner conduit structure, and sealing surface is only about 200mm.
Therefore, the beneficial effects of the utility model are; Owing to adopted above-mentioned hermetically-sealed construction, movable sealing face can be reduced more than 1/2, the static seal face reduces 60-80%.Simple in structure, sealing is reliable.When realizing water-saving function, greatly improved reliability, reduced the production difficulty, prolonged the service life of product.

The specific embodiment
Below in conjunction with drawings and Examples water saving sleeve washer primary sealing surface hermetically-sealed construction of the present utility model is elaborated.
Fig. 1 is used for electrical motor gearshift sleeve washer schematic diagram for structure of the present utility model.
In Fig. 1, wash shaft 16 links to each other with impeller, and dehydrating shaft 38 links to each other with interior bucket 10, and their clutch and speed change realize by other existing controlling organizations.Be provided with wash shaft oil sealing 17 between wash shaft upper end and the dehydrating shaft.Interior bucket 10 seals, and has rhone with the gimbal connecting portion on it, and it is connected with stopping-off piece 9 by screw 11, seals with large sealing packing ring 12; Stopping-off piece 9 is by small sealing ring 13 and 22 sealings of steps type seal cover.The effect of dehydrating shaft oil sealing 3 is the sealings that realize dehydrating shaft 38, and water seal 4 is closely linked with axle sleeve 1, and its lip part fits tightly with steps type seal cover 22, realizes sealing.One circle hole is arranged on the axle sleeve 1; Can realize draining, on the outer bucket 5 annular projection be arranged, screw hole is arranged on the projection, seal cover 7 is realized sealing and formation cavity 15 by seal gasket 6 and outer bucket 5 under the effect of screw 8.Be provided with rolling bearing 2 between axle sleeve and the dehydrating shaft, outer bucket 5 links to each other with cavity 15 and has internal drainage hole 23, mode and internal drainage hole 23 that inner conduit 24 usefulness are gluedd joint are tightly connected, and the other end of inner conduit 24 and joint 26 glued joint, and joint 26 is tightly connected by joint sealing circle 25 and outer bucket 5 again.Air chamber 27 is communicated with interior barrel 10 formation, and water level detecting hole 28 links to each other with level sensor and detects interior barrel 10 interior water level.
Two mouths of pipe on the draining valve body 29 respectively with outer bucket 5 on two holes be tightly connected, spool 31 is under the pressure of stage clip 34, with valve body 29 sealings; Also can under the effect of tractor 37, spool 31 be drawn back, realize draining by extension spring 36 and draining pull bar 32.
During washing, inwardly water filling in the bucket 10, do not have water in the outer bucket 5 this moment, and spool 31 is under the pressure of stage clip 34, and with valve body 29 sealings, water can see through interior bucket mesopore 14 and sealing trepanning 21 arrives in valve body 29 and the air chamber 27, but can not discharge.
During draining, spool 31 is opened, and the water in the interior bucket 10 arrives valve body 29 by interior bucket mesopore 14 and sealing trepanning 21, discharges washing machine from drainpipe 35.
During dehydration, bucket 10 top in water rises under action of centrifugal force enters in the outer bucket 5 from the osculum at top, arrives valve bodies 29 by outer bucket spillway hole 30 again, from drainpipe 35 discharge washing machines.
Fig. 2 is used for the sleeve washer schematic diagram of common band clutch for structure of the present utility model.Wherein 39 is clutch, and 40 is sealing ring.
Because this washing machine does not have the axle sleeve 1 among Fig. 1, therefore make the boss location on the bucket 5 outside, load onto the effect that the sealing ring 40 that has a circle osculum replaces Fig. 1 bottom bracket axle 1, sealing ring 40 can be an one with outer bucket; All the other structures are identical with Fig. 1 with effect.
Fig. 3, Fig. 4 are the structure chart of structural ledge formula sealing shroud 22 of the present utility model, and its upper opening is bigger, are convenient to dispersed placement osculum on interior bucket 10 and stopping-off piece 9, to improve their intensity; Lower openings is less, and the inside is used for draining, and the outside closely contacts with water seal 4 and realizes that sealing, its top also have screw hole 19 to be fixed on interior bucket bottom by screw 18.
