Referring to fig. 4-8, in some embodiments of the present application, each filter assembly 220 includes a filter shutter 222 and a first restoring member 224. The filtering shroud 222 is pivotally attached to the inside of the corresponding work surface and the filtering shroud 222 has a screen portion 225 thereon opposite the inlet aperture 216 of the work surface. First return member 224 is adapted to provide a first force to filter shutter 222 to block inlet aperture 216. And filter shutter 222 is configured to rotate against a first force against the thrust of the water stream toward the interior of the body to open inlet aperture 216.

The filter shutter 222 in this embodiment is pivotally attached to the inside of the first work surface 214 or the second work surface 215 and is capable of rotating relative to the inlet aperture 216 to either block or unblock the inlet aperture 216. In the rotating process of the inner barrel 100, when water in the inner barrel 100 flows through the first working surface 214, the filtering shield 222 arranged at the first working surface 214 is thrust by the water flow, so that the filtering shield 222 rotates towards a direction far away from the water inlet hole 216, the water flow containing impurities enters the accommodating chamber 212, meanwhile, the filtering shield 222 on the second working surface 215 is located at a position for shielding the water inlet hole 216 on the second working surface 215, and the filtering screen part 225 of the filtering shield 222 can play a role in filtering the water flow passing through the filtering shield 222, so that the impurities in the water are filtered in the accommodating chamber 212.

Referring to fig. 4-9, in some embodiments of the present application, the body has a mounting surface 218 connected to the inner barrel 100, the mounting surface 218 may be disposed between the first working surface 214 and the second working surface 215, and the mounting surface 218 conforms to a surface of the inner barrel 100. The mounting surface 218 is opened with an impurity discharge port 219 for discharging impurities remaining in the receiving chamber 212, and the lifting rib 200 further includes an impurity discharge member openably and closably provided at the impurity discharge port 219 and configured to open the impurity discharge port 219 by a centrifugal force when the inner cylinder 100 rotates.

The foreign substance discharge assembly includes a blocking plate 310 and a second restoring member 320. The shutter 310 is pivotally connected to the body for closing the foreign matter discharge port 219, and the foreign matter discharge port 219 is opened by rotating toward the outside of the body by the centrifugal force while the inner tub 100 rotates.

The second restoring member 320 serves to provide the shutter 310 with a second force to close the foreign substance discharge port 219, and the shutter 310 is configured to rotate toward the inside of the body against the second force by a centrifugal force when the inner cylinder 100 rotates, to open the foreign substance discharge port 219.

In the present embodiment, the shutter 310 is pivotally connected to the body at the foreign matter discharge port 219, enabling to close the foreign matter discharge port 219. When the inner cylinder 100 rotates, the baffle plate 310 rotates in a direction away from the foreign matter discharge port 219 by a centrifugal force to open the foreign matter discharge port 219 for the purpose of discharging foreign matter.

Referring to fig. 4, a washing process of the drum-type washing machine 10 can be divided into a washing stage and a dehydrating stage, and the rotation speed of the drum 100 in the washing stage is generally lower than that of the drum 100 in the dehydrating stage. In some embodiments of the present application, to improve the operation efficiency of the filter assembly, the foreign matter discharge port 219 is maintained in a closed state while the drum type washing machine 10 is in the washing stage. If the foreign matter discharge port 219 is in an open state during the washing process, the water entering the receiving chamber 212 directly flows out from the foreign matter discharge port 219 to the outer tub 110 without being filtered by the filter assembly 220, and the water returns to the inner tub 100 from the outer tub 110 through the dewatering holes, which reduces the efficiency of the lifting rib 200 in collecting foreign matters. In order to solve the above problem, in the embodiment of the present application, a person skilled in the art can select the second reset member 320 with a suitable specification according to the operation condition (such as the rotation speed of the drum 100 during the washing phase) of the drum-type washing machine 10, so that the centrifugal force applied by the drum 100 to the baffle plate 310 during the washing phase is smaller than the second acting force provided by the second reset member 320, and the baffle plate 310 is located at the position for closing the impurity discharge port 219.

In other embodiments of the present application, the second force provided by the second restoring member 320 is configured to be greater than the centrifugal force applied by the drum 100 to the barrier 310 during the washing stage, and the second force provided by the second restoring member 320 is less than the centrifugal force applied by the drum 100 to the barrier 310 during the dehydrating stage. That is, the shutter 310 is positioned to close the foreign matter discharge port 219 during the washing stage, and the shutter 310 is positioned to open the foreign matter discharge port 219 during the dehydration stage, so that the foreign matter in the receiving chamber 212 is discharged during the dehydration stage.

In some embodiments of the present application, the baffles 310 are split, that is, the number of the baffles 310 is two, and two baffles 310 are respectively disposed at both sides of the impurity discharge port 219 to open or close the impurity discharge port 219 by rotating simultaneously.

Referring to fig. 10, in other embodiments of the present application, the baffle 310 may be provided as one, one side of which is pivotally connected to the body at the impurity discharging port 219, and is rotated at the same time to open or close the impurity discharging port 219.

The mounting surface 218 is inclined toward the impurity discharge port 219 in some embodiments of the present application such that the impurities in the receiving chamber 212 are adjacent to the impurity discharge port 219 to facilitate discharge.

In some embodiments of the present invention, the inner cylinder 100 has a drainage hole 410 at a position connected to the mounting surface 218 to provide a rotation space required for the rotation of the barrier 310, and to drain foreign substances through the drainage hole 410 when the barrier 310 is opened. And finally the foreign materials are discharged through a drain pipe 130 connected to the outer tub.

The working principle of the invention is as follows: when the water flow in the drum-type washing machine 10 flows through the first working surface 214 during the washing process, the first working surface 214 is pushed by the water flow and opens the filter assembly 220 disposed at the first working surface 214 under the pushing force of the water flow, so that the water flow enters the receiving chamber 212 from the water inlet hole 216 on the first working surface 214, the filter assembly 220 on the second working surface 215 is located at a position for shielding the water inlet hole 216, and when the water flow flows out of the receiving chamber 212 from the water inlet hole 216 on the second working surface 215, the filter screen portion 225 on the filter assembly 220 at the position filters and retains the impurities in the water flow in the receiving chamber 212. The drum type washing machine 10 opens the foreign matter discharge port 219 against the force of the second restoring member 320 by the centrifugal force with the rotation of the inner tub 100 during the dehydration process, so that the foreign matter in the receiving chamber 212 is discharged from the foreign matter discharge port 219. Through the two processes, the drum-type washing machine 10 can automatically collect and discharge impurities without user intervention, and the use experience of the user is improved.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
