The working process at this time is as follows: when the drum washing machine starts washing, the water level in the drum 100 rises to a certain height, the drum 100 starts to rotate in a certain direction (for example, anticlockwise), when each lifting rib 200 sequentially rotates to the lowest position of the washing cavity 110, water in the washing cavity 110 enters the water cavity 240 through the first water through hole 211, the second water through hole 221 and the third water through hole 231, the water cavity 240 starts to store water, the first side surface 210 is a water inlet surface which is mainly and firstly contacted with a water level line, the first water through hole 211 is a main water inlet hole, the second water through hole 221 and the third water through hole 231 are auxiliary water inlet holes, along with the continuous rotation of the drum 100, a certain amount of water can be stored in the lifting rib 200 from the contact water level line to the leaving water level line, and in the process that the lifting rib 200 rotates from the water outlet position to the highest position of the washing cavity 110, under the driving of inertia, the inner wall (namely, the fourth side surface 140) of the drum 240, A part of water is stored between the second side 220 and the third side 230, when the lifting rib 200 rotates to the highest position of the washing chamber 110, the water in the water chamber 240 is mainly sprayed out from the second through hole 221, and meanwhile, the first through hole 211 and the third through hole 231 also serve as auxiliary spraying holes, thereby improving the spraying area and the spraying effect.
When spraying, the first water through hole 211 and the third water through hole 231 spray water toward both sides of the lifting rib 200, so that the laundry in the washing chamber 110 is sprayed more omnidirectionally.
With respect to the specific arrangement of the first water passage hole 211, referring to fig. 4, in some embodiments of the present application, the first water passage hole 211 is a tapered hole, and the inner diameter thereof gradually decreases from the first side surface 210 to the inside of the water chamber 240.
When water in the washing chamber 110 enters the water chamber 240 through the first water passing hole 211, the water is introduced easily and the water inlet efficiency is improved because the large caliber of the first water passing hole 211 faces outwards.
Referring to fig. 5, a plurality of rows (for example, two rows) of first water passing holes 211 are formed in the first side surface 210 along the length direction thereof, and increasing the number of the water passing holes is advantageous to further improve the water inlet efficiency.
The inner diameter of the first water passage hole 211 close to the cylinder 100 is smaller than the inner diameter of the first water passage hole 211 far from the cylinder 100, so that the structural strength of the first side surface 210 can be ensured on the basis of ensuring the water inlet and spraying effects.

When the water in the water chamber 240 is sprayed into the washing chamber 110 through the second water through hole 221, the water in the water chamber 240 is sprayed advantageously due to the large diameter of the second water through hole 221 facing inwards, thereby improving the spraying effect.
Referring to fig. 5, the second water passing holes 221 have a plurality of rows, for example, two rows, and increasing the number of the water passing holes is advantageous to improve the shower effect.
The inner diameter of the second water through hole 221 close to the first side surface 210 is smaller than the inner diameter of the second water through hole 221 far from the first side surface 210, so that the structural strength of the second side surface 220 can be ensured on the basis of ensuring the water inlet and spraying effects.
Regarding the specific arrangement of the third through water hole 231, in some embodiments of the present application, referring to fig. 4, the inner diameter of the third through water hole 231 is gradually decreased from the third side surface 230 to the direction inside the water chamber 240.
In the process that the lifting rib 200 rotates from the water outlet position to the highest position of the washing chamber 110, the third side surface 230 is located below, and the small diameter of the third water through hole 231 faces inwards, so that the outflow of water in the water chamber 240 through the third water through hole 231 can be reduced, and the water storage capacity of the water chamber 240 is improved.
In some embodiments of the present application, referring to fig. 4, a fourth water through hole 141 is formed on a wall (i.e., the fourth side 140) of the cylinder 100 enclosing the water cavity 240.
When the washing machine is operated for dewatering, the water in the water chamber 240 is thrown out through the fourth water through hole 141 along the fourth side 140 under the action of centrifugal force due to high rotation speed, thereby ensuring the dewatering function.
For the specific arrangement of the fourth water through hole 141, in some embodiments of the present application, the fourth water through hole 141 is a tapered hole, the diameter of the tapered hole gradually decreases from the water cavity 240 to the outer side of the cylinder 100, and the large diameter of the fourth water through hole 141 faces inward, so that water in the water cavity 240 is thrown out when dehydration is performed.
In some embodiments of the present application, referring to fig. 2, one end of the lifting rib 200 contacts with the front flange 120 of the cylinder, and the other end contacts with the rear flange 130 of the cylinder, so as to achieve sealing, thereby preventing the problem that water runs off when the lifting rib 200 does not reach the highest position when the cylinder 100 rotates.
For the specific assembly structure between the tie bar 200 and the front and rear flanges 120 and 230, the embodiment is not particularly limited, and may be sealed or formed into an integral structure.
When the inner cylinder in this embodiment rotates at a low speed for washing, the lifting rib 200 can store a part of water in the process of rotating from the bottom to the top of the washing cavity 110, and when the lifting rib 200 rotates to the top, the lifting rib sprays by using the self gravity of water and the eddy force brought by the component velocity of the rotational acceleration, so that the clothes which cannot be flooded by the upper layer of water can be washed, and meanwhile, water can be saved, and the partial reduction of the water level is compensated by the spraying washing effect.
When the inner cylinder rotates at a high speed for dehydration, water in the water cavity 240 is discharged along the cylinder wall (specifically, the fourth water through hole 141) by centrifugal force, and the spin-drying function is not affected.
The first water through hole 211, the second water through hole 221, the third water through hole 231 and the fourth water through hole 141 are all tapered holes, have guidance, and the heavy-calibre end helps guiding water flow to enter, does benefit to water storage in the rotation process, and the reducible rivers of small-calibre end flow out increase the rivers outflow speed simultaneously.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
