8. A washing machine as claimed in any one of claims 1 to 7, comprising a water collecting unit provided outside the inner tub, wherein the driving mechanism is mounted on the water collecting unit corresponding to the sealing mechanism, and has an output end which is extendable and retractable up and down:

9. The washing machine as claimed in claim 8, further comprising a locking mechanism mounted on the water collecting device, the locking mechanism having a locking rod moving up and down, a locking hole for locking the inner tub by cooperating with the locking mechanism is provided on an outer wall of a bottom of the inner tub, and the locking rod moves up and is inserted into the locking hole to lock the inner tub, and then an output end of the driving device is protruded to push the sealing mechanism open for draining.

10. The washing machine as claimed in any one of claims 1 to 9, wherein the drain port is provided at a position near the rim on the bottom of the inner tub, and the drain port is inscribed in the circumference of the rim of the bottom of the inner tub.
