Detailed Description

The invention is described in further detail below with reference to the accompanying examples.

As shown in fig. 1 to 4, the present invention provides a dual drum washing machine, which comprises a machine housing 1, a first outer drum 21, a second outer drum 22, a first inner drum 31, a second inner drum 32, a driving motor 82, a cam 8, a rocker 9, a driving bevel gear 7, a first bevel gear 71, a second bevel gear 72, a first swing link 41, a second swing link 42, a first rotating shaft 710, a second rotating shaft 720, a first roller 51, a second roller 52, a first belt 61 and a second belt 62.

Wherein, a first outer cylinder 21 and a second outer cylinder 22 are fixedly arranged in the machine shell 1, a cylinder cover is arranged at the outer end of each outer cylinder on the machine shell 1, a first inner cylinder 31 is rotatably arranged in the first outer cylinder 21, a second inner cylinder 32 is rotatably arranged in the second outer cylinder 22, a first rotating shaft 710 and a second rotating shaft 720 are oppositely arranged in the machine shell 1, a first bevel gear 71 and a first swing rod 41 are arranged on the first rotating shaft 710, a second bevel gear 72 and a second swing rod 42 are arranged on the second rotating shaft 720, a first roller 51 in transmission connection with the first inner cylinder 31 is arranged at the first inner cylinder 31, a first clutch is arranged on the rotating shaft of the first roller 51, a first arc section 411 in contact with the first roller 51 is formed at the outer end of the first swing rod 41, a second roller 52 in transmission connection with the second inner cylinder 32 is arranged at the second inner cylinder 32, and a second clutch is arranged on the rotating shaft of the second roller 52, a second arc section 421 contacting with the second inner cylinder 32 is formed at the outer end of the second swing link 42, a first belt 61 is wound on the first roller 51, a first ring groove for embedding the first belt 61 is formed on the first roller 51, one end of the first belt 61 is connected with the first arc section 411, the other end of the first belt 61 is connected with the second arc section 421, a second belt 62 is wound on the second roller 52, a second ring groove for embedding the second belt 62 is formed on the second roller 52, one end of the second belt 62 is connected with the first arc section 411, the other end of the second belt 62 is connected with the second arc section 421, a driving bevel gear 7 engaged with the first bevel gear 71 and the second bevel gear 72 is arranged at the relative interval between the first rotating shaft 710 and the second rotating shaft 720, a swing link 9 is arranged on the rotating shaft of the driving bevel gear 7, a driving motor 82 is arranged at the swing link 9, a cam 8 is arranged at the output end of the driving motor 82, the outer peripheral wall of the cam 8 is provided with a closed cam groove 81, the rocker 9 is provided with a driven body 91 limited in the cam groove 81, preferably, the driven body 91 is a roller rotatably arranged on the rocker 9, the track of the cam groove 81 meets, and when the cam 8 rotates for a circle, the cam 8 drives the rocker 9 to swing back and forth once.

The double-drum washing machine has different washing amount of the two drums, and has several washing modes selected based on the amount and type of the washed clothing. When the clothes need to be classified and cleaned and the quantity of the clothes to be cleaned is large, the first clutch and the second clutch work simultaneously, and the two rollers are cleaned synchronously; when the washing amount of the clothes is relatively small, the first clutch works, the second clutch is separated, and the clothes are cleaned by using the first inner cylinder 31 with relatively small washing amount; when the laundry amount is not much, the second clutch is operated, the first clutch is disengaged, and the laundry is washed by the second drum 32. The operation of the washing machine of the present invention will now be briefly described by taking the first drum 31 as an example for washing the laundry.

When the first inner barrel 31 is needed to clean clothes, a barrel cover of the first inner barrel 31 is opened, the clothes to be cleaned are put into the first inner barrel 31, the barrel cover is closed, clean water and laundry detergent are automatically added, the driving motor 82 drives the cam 8 to rotate, the cam 8 drives the rocker 9 to swing through the cam groove 81, the rocker 9 drives the driving bevel gear 7 to alternately rotate clockwise and anticlockwise, the driving bevel gear 7 drives the first bevel gear 71 and the second bevel gear 72 to alternately rotate in opposite directions, correspondingly, the first swing rod 41 coaxial with the first bevel gear 71 swings back and forth, the second swing rod 42 coaxial with the second bevel gear 72 also swings back and forth synchronously, so that the first arc-shaped section 411 and the second arc-shaped section 421 alternately move oppositely and oppositely in the circumferential direction, the first belt 61 and the second belt 62 are pulled, the first belt 61 drives the first roller 51 to rotate back and forth, the second belt 62 drives the second roller 52 to rotate back and forth, because the second clutch is disengaged, the second roller 52 cannot drive the second inner cylinder 32 to rotate, and the first clutch is in an operating state, the first roller 51 drives the first inner cylinder 31 to rotate, and the first inner cylinder 31 cleans the clothes. And for other situations, the difference is only limited to the states of the two clutches, and whether the roller can drive the corresponding inner cylinder to rotate or not is judged. Therefore, it is no longer cumbersome here.

To sum up, when a relatively large amount of clothes need to be cleaned and the clothes need to be classified and cleaned, the clothes are classified and placed into the first inner cylinder 31 and the second inner cylinder 32 according to the requirements, the first clutch and the second clutch work simultaneously, the driving motor 82 drives the driving bevel gear 7 to rotate clockwise and anticlockwise alternately through the cam 5 and the rocker 9, the driving bevel gear 7 drives the first bevel gear 71 and the second bevel gear 72 to rotate in opposite directions, the first swing rod 41 and the second swing rod 42 swing oppositely, the first belt 61 and the second belt 62 drive the first roller 51 and the second roller 52 to rotate back and forth in opposite directions, and the first inner cylinder 31 and the second inner cylinder 32 clean the clothes simultaneously; when the clothes amount is relatively small, one of the two drums can be selected for washing due to different washing amounts of the two drums, and at the moment, the clutch corresponding to the other drum is separated, so that the application of multiple washing modes of the washing machine is realized.
