Water-free washing machine between inner and outer barrels

Abstract

A washing machine includes an outer barrel and an inner barrel rotatably arranged in the outer barrel. During the washing/rinsing process, the inner barrel contains water, and there is no water between the inner barrel and the outer barrel. A drainage hole is arranged on the bottom of the inner barrel. A drain-sealing device and a driving device are arranged on a bottom of the inner barrel. The drain-sealing device comprises a sealing part cooperating with the drainage hole to control the opening/closing of the drainage hole, and a connecting part connected with the driving device. During washing/rinsing, the sealing part of the drain-sealing device keeps the drainage hole closed. During draining/dehydrating, the drain-sealing device opens the drainage hole under the action of the driving device. The drain-sealing device and the driving device are installed on the inner barrel, and rotate with the the inner barrel during dehydrating.
