Turn needle roller outer ring 69 on hub 90 and to be inserted in together with cylinder needle roller 68 by being fixed on cylinder and to be fixed on outer bearing and to prop up and hold round 89 last points, slowly rotary drum turns hub 90, the hub splined hole 94 that turns that cylinder is turned on hub 90 is aimed at the axle head spline 49 on motor shaft 40 and is matched, continue pushing cylinder and turn hub 90, the overall and outer bearing of the cylinder needle roller 68 on needle roller outer ring 69 is propped up hold round 89 to match completely; First take after step backing-up screw 74 passes through axial location back-up ring 70 centre bore and match with the axle head screw 47 on motor shaft 40, the two flat side bumpers of axial location back-up ring 70 on step backing-up screw 74 are takeed between caps 73 and axle head spline 49 outer face has one millimeter axially freely to measure; Match with the hub end face screw 97 that turns that cylinder turns on hub 90 pass through the positioning retainer ring through hole 76 on axial location back-up ring 70 again with five back-up ring screws 77 after, axial location back-up ring 70 is also fastened on cylinder and turns on hub 90 outer face; After finally passing through the through hole on locking catch 71 and the positioning retainer ring through hole 76 on axial location back-up ring 70 successively with a back-up ring screw 77, the hub end face screw 97 that turns also turned with cylinder on hub 90 matches, on any flat limit that catch corner edges 72 on locking catch 71 is aimed on two flat side bumper shoulder caps 73, play locking effect.

Install.

Three, the utility model washing process is as follows:

Before washing, open end can door 102, puts into the rolling inner core 108 putting into cylindric washer 401 by washing clothes etc., closes cylinder door 102;

Solvent pump 407 extracts the solvent of 403 li, clean liquid case through connecting branch 409, is injected in cylindric washer 401, washs the clothing be immersed in solvent through the 3rd pipeline 416.After having washed, solvent is discharged in soiling solution tank 402 through the first pipeline 404 after the second filter 408 coarse filtration.

When the motor is activated, the moment of torsion that electromagnetic force produces is by the axle head spline 49 on motor shaft 40, and the hub splined hole 94 that turns turned on hub 90 through cylinder passes to cylinder rear board 181, drives whole rolling inner core 108 to rotate; Disc type motor assembly 110 drives cylindric washer 401 High Rotation Speed to take off liquid, to make the solvent on clothing few as much as possible.

In this process, the shape of washing clothes and volume are irregular caused vibrations, part vibrations are hung by four in interior surge combination part and are drawn welding spring buffer 169 and two supporting welding spring buffers 161 to be absorbed, another part vibrations are absorbed by the upper spring 230 among outer buffering wheels 120 and lower spring 250, and the utility model overall operation is steady.

After de-liquid completes, heat pump clothes-drying system starts, air in condenser 411 cartridge heater, blower fan delivers to heats laundry in cylindric washer 401 hot-air, residual solvent on clothing flashes to solvent vapo(u)r at relatively high temperatures, the mixture of solvent vapo(u)r and air arrives evaporimeter 410 place under fan action, and solvent vapo(u)r condenses into liquid solvent in evaporimeter 410 place's heat release and is recovered out.

In clothes drying process, solvent filtration system works simultaneously, under the effect of solvent pump 407, solvent in soiling solution tank 402 can be entered into after the first filter 406 filters by the arrival end of the second pipeline 405 and obtain clean solvent, then be pumped in clean liquid case 403 by the first triple valve 414, solvent pump 407 and the second triple valve 415 successively, and under the effect of solvent pump 407, clean solvent in clean liquid case 403 can be pumped in cylindric washer 401 by connecting branch 409, solvent pump 407, second triple valve 415 successively, realizes again utilizing.

Four, the utility model has following outstanding substantive distinguishing features and the effect that improves significantly:

(1), owing to adopting above setting, user is in and can washs the easy high-grade clothing shrinking and should not wash, and effectively prevent the problem with other clothing cross infection germ in drycleaner's.In addition, the Domestic dry washing machine in the present embodiment also has little, the lightweight advantage of volume, is relatively applicable to family expenses.In addition, owing to being provided with solvent recovering system, the solvent after washing can being recycled again, there is the advantage of saving the energy and environmental protection.

Be summarized as:

A. volume is little, and structure is simple, does not need extra heat source (as vapours, electric heater), is applicable to family expenses.

B. energy consumption is low, and cost is low; Heating-up temperature less than 75 DEG C, does not damage the high-grade clothing of dry-cleaning.

C. environmental protection, does not need to consume water and carrys out condensing solvent steam.

(2), the disc type motor assembly 110 of the utility model core component and the syndeton of rolling cylindrical shell 108 are: have gap between the member through-hole 804 of component component 80 and the rotating shaft of motor shaft 40 overhanging section 46, organic sealing assembly 48 between the component stepped hole 84 of component component 80 and the rotating shaft of motor shaft 40 overhanging section 46, between component stepped hole 84 and member through-hole 804, organic envelope dismantles groove 808, is convenient to specific purpose tool demountor sealing assembly 48; Outer bearing on component component 80 props up and holds round 89 and support cylinder needle roller 68 on no inner-ring bearing 60, avoids motor shaft 40 and bears any radial load.It is that the error of 100 millimeters of unit sizes is less than or equal to 0.004 millimeter that outer bearing props up the axiality held round between 89 and component for adjusting ring 82 cylindrical, is similar to absolute concentric shafts.

(3) permanent magnet 12 cross section, in the utility model is isosceles trapezoid, and axial magnetic field increases from inside to outside gradually, avoids magnetic field to occur saturated in inner radius, improves the utilization ratio of permanent magnet 12.In addition, owing to being formed with taper seat air gap between stator core 26 and rotor core 11 and permanent magnet 12, increase air gap effective area, further improve the utilization effect of permanent magnet 12.

(4) housing flange 122 on shell front panel 104 opening, on described casing 101 is provided with described cylinder door 102 just above, and the outer drum flange 121 on described washing urceolus 103 opening is the airtight vibrations being connected with bellow seal ring 124 bellow seal ring 124 and not only having accomplished static sealing but also can bear certain amplitude of oscillation between the back side just above and after described housing flange 122.

(5), under the utility model cushions the synergy of upper spring 230 among wheels 120 and lower spring 250 and plane bearing ball 277 outside, can in movement arbitrarily on uneven ground of jolting, buffering effect is better, and mobile specially turn to sensitive.

(6) the interior surge combination part, in the utility model comprises four and hangs and draw welding spring buffer 169 and two supporting welding spring buffers 161; No matter the inner rotating speed speed of cylindric washer 401 or imbalance are trembled, and the dual-stage buffer buffer structure of above-mentioned interior surge combination part, can guarantee that the utility model overall operation is steady all the time.
