Preferably, the water collecting flow passage comprises a plurality of water collecting flow passages which are uniformly distributed along the circumferential direction of the rear cylinder bottom of the inner cylinder 4.
In order to cooperate with a water collecting device to collect water, one end, opposite to the rear cylinder bottom, of the inner cylinder 4 is a front cylinder cover, the diameter of the front cylinder cover is smaller than that of the rear cylinder bottom, and the side wall of the inner cylinder 4 is obliquely and upwards arranged from the front cylinder cover to the rear cylinder bottom.
In order to realize the water collecting effect of the water collecting device, the inner cylinder 4 is rotated in coordination with the rotation of the inner cylinder 4, the washing water is gathered on the surface of the side wall of the inner cylinder 4 under the centrifugal action, and the washing water is gathered from the front cylinder cover to the bottom of the rear cylinder along the inclined side wall of the inner cylinder 4 due to the inclined structure of the side wall and is introduced into the water collecting cavity through the water collecting flow channel arranged at the position.
Therefore, in the dehydration process of the drum washing machine of the embodiment, the water collection and drainage are realized by means of the high-speed rotation of the inner drum 4, the drainage process can be added to the drainage after the washing process, and the drainage is realized by improving the high-speed rotation of the inner drum 4.
As a preferred implementation manner of this embodiment, the water collecting device described in this embodiment includes a cover plate, and the cover plate is installed on the inner wall of the rear cylinder bottom of the inner cylinder: the cover plate is internally provided with a closed hollow cavity to form a water collecting cavity and a water collecting flow channel, or the cover plate is internally provided with an open groove, and the cover plate is connected with the inner wall of the bottom of the inner cylinder at the rear cylinder bottom in a sealing manner to seal the groove to form the water collecting cavity and the water collecting flow channel.
As a preferred embodiment of this embodiment, the upper surface of the water collecting device is configured with a protrusion structure protruding from the bottom of the inner tub, and the protrusion structure can lift the laundry during washing, thereby improving the washing effect.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
