If the first tank 11 is not used to wash, the control system 19 determines that whether the second tank 12 is used to wash, as shown in step S507. By the abovementioned steps, the control system 19 determines that whether the first tank 11 or the second tank 12 is used to wash alone. If the first tank 11 is determined to wash in step 502, the washing medium is put into the first tank 11, and water is conducted to the first tank 11 by the first inlet device 161 from the inlet opening 2610 of the first inlet device 161, as shown in step S503. And then, the first tank 11 is driven to perform washing procedures by the driving unit 18, as shown in step S505.

[0077] The control system 19 determines that whether the water with washing medium in the first tank 11 is drained out, as shown in step S506. If the water with washing medium is determined to be drained out, the first outlet device 162 is controlled to conduct water out from the outlet opening 2620 of the first outlet device 162, as shown in step S514. If the water with washing medium is determined not to be drained out, the first outlet device 162 is controlled to conduct water to the first main pipe 15, and the second inlet device 163 is controlled to conduct water with washing medium to the second tank 12, as shown in step S508. And then, the second tank 12 is driven to perform washing procedures by the driving unit 18, as shown in step S511.

[0078] If the second tank 12 is determined to wash in step S507, washing medium is put into the second tank 12, as shown in step S509. And then, the second tank 12 is driven to perform washing procedures by the driving unit 18, as shown in step S511.

[0079] The control system 19 determines that whether the water with washing medium in the second tank 12 is drained out, as shown in step S512. If the water with washing medium is determined to be drained out, the second outlet device 164 is controlled to conduct water out from the outlet opening 2620 of the second outlet device 164, as shown in step S515. If the water with washing medium is determined not to be drained out, the second outlet device 164 is controlled to conduct water to the second main pipe 150, and the first inlet device 161 is controlled to conduct water with washing medium to the first tank 11, as shown in step S513.

[0080] By using the washing machine with a plurality of tanks of the present invention and the washing method thereof, each tank can be determined to wash or not, water and washing medium can be recycled between different tanks, and the washing procedures is reduced.

[0081] Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the scope of the invention specified by the claims.
