Referring to Fig. 1 to 3, washer-extractor of the present utility model comprises a urceolus 14 that is installed on the framework 15, the internal sleeve of urceolus 14 is equipped with the interior cylinder 9 that is driven rotation by main shaft 10, and inside and outside tube arranges that coaxially a door body 2 is fixedly mounted on the front panel of urceolus.Inside and outside tube 9 and 14 is so-called horizontal arrangement form, and promptly its axis is parallel to the ground level layout.

Urceolus 14 is rolled by metallic plate, for example steel plate and is welded, and water inlet, water discharge outlet, steam inlet and washing agent is set on the outer cylinder body adds mouth.Inner core 9 is rolled by corrosion resistant plate and is welded, and many apertures is arranged on the inner tube wall and the rib plate is housed, and plays the effect that promotes and rub clothing.As can see from Figure 2, main shaft 10 is a cantilevered, is connected with inner core 9 transmissions ground.Also windowpane can be housed on the door body 2, so that observe the washing situation that liquid level just reaches clothings in the interior cylinder 9.Control panel 1 is installed in the front of washer-extractor, as shown in Figure 1.

For reducing vibrations, inventor of the present utility model has designed unique dynamical system, as shown in Figure 2.This dynamical system comprises: 3, one dehydrations of the motor that washing and balance are used are with motor 8, and motor 3 and 8 power are by belt and belt pulley transmission.When washing or during balancing run, motor 3 work, electromagnetic clutch 6 adhesives, motor power through belt 5 and 12 and

belt pulley

4,41,13,11 double reductions after drive in cylinder 9 low speed rotation; When carrying out dehydrating operations, electromagnetic clutch 6 is thrown off, and dehydration is directly delivered to belt pulley 13 with the power of motor 8 through centrifugal clutch 7, electromagnetic clutch 6, cylinder 9 rotation at a high speed in driving after slowing down through the one-level belt again.Above-mentioned motor 3 and 8 and clutch 6 and 7 be installed on the framework 15.It should be noted that in addition the used electromagnetic clutch 6 of the utility model is commercially available standarized component, for example DLM15-16

Owing to adopted two motors 3 and 8 and belt transmission, avoided in the prior art in drum rotation speed when changing change-speed gearing enter or the impact when breaking away from engagement, thereby reduced vibrations.

Fig. 3 expresses urceolus 14 and is suspended on situation on the framework 15 by damper 16, and urceolus 14 is hung by 4 dampers 16, can only see two dampers in Fig. 3.Concrete suspended structure as shown in Figure 4, this is a spring---a fluid damper 16, it comprises a closed cavity 17, spring 18, piston rod 212, fluid 22 is arranged in the cavity 17 and be installed in the piston that has pore 21 211 of bar 212 1 ends.During installation, the hole on the framework 15 is passed in the upper end of piston rod 212, and with the nut locking, this boring ratio piston rod 212 is big slightly again.The lower pole 213 of damper 16 passes the big slightly hole of size on the plate 141, and locks with nut.Plate 141 is to be fixed on outwardly directed wing plate on the periphery wall of urceolus 14, and plate 141 can be welded on the urceolus 14.
