The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

Referring to fig. 1, the washing apparatus is a drum washing machine that washes laundry using water, and in other embodiments, the washing apparatus may also use other fluids for washing other laundry. Wherein fig. 7-9 are the same cross-sectional view, but with different numbering, to show the various components more clearly.

Referring to fig. 1, the washing apparatus includes a cabinet 10, an outer tub nested in the cabinet 10, and a washing tub 20, the outer tub is fixed in the cabinet 10 for containing washing water, and the washing tub 20 is rotatably disposed in the outer tub; a clothes inlet is formed on the front plate of the cabinet 10, the door 30 is hinged on the front plate, the door 3 is used for opening or closing the clothes inlet, and the washings (namely the clothes) are put into the washing drum 20 through the clothes inlet; lifting ribs 40 are fixed on the inner wall of the washing drum 20, and the lifting ribs 40 are used for lifting clothes when the washing drum rotates, so that beating washing of the clothes is realized; preferably, three lifting ribs 40 are uniformly distributed on the circumference of the washing drum 20. In other embodiments, the outer tub may not be provided on the washing machine.

The lifting rib 40 is internally provided with a water containing cavity 41 capable of containing washing water, and when the washing equipment is used for washing, the washing drum 20 rotates in a positive and negative alternative interval manner to divide the space in the water containing cavity 41 into a plurality of water containing chambers; specifically, at least one forward water-containing chamber 411 for jetting water when the washing drum 20 rotates forward and at least one reverse water-containing chamber 412 for jetting water when the washing drum 20 rotates reversely are arranged in the water-containing cavity 41; thus, during the washing process, when the washing drum 20 rotates forwards or backwards, the water-repellent ribs 40 can play a role in jetting water to impact the washings in the washing drum 20, and the impact on the washings is improved. Referring to fig. 3, when the washing drum 20 rotates forward, when the lifting rib 40 moves to the highest point along with the washing drum 20, the forward rotation accommodating compartment 411 is in a jet flow state and impacts the clothes, so that the impact on the clothes is increased, and the water flow has a large drop, so that the impact on the clothes is ensured, and the washing ratio of the washing machine is improved; referring to fig. 4, when the washing drum 20 rotates reversely, when the lifting rib 40 moves to the highest point along with the washing drum 20, the reverse water-containing chamber 412 is in a jet flow state, so that the impact on the clothes is increased, and the water flow has a large drop height, so that the impact on the clothes is ensured, and the washing ratio of the washing machine is improved.

For the scheme of realizing the jet flow of the forward rotation water-containing chamber 411 during the forward rotation and the jet flow of the reverse rotation water-containing chamber 412 during the reverse rotation of the washing cylinder 20, various modes can be adopted, for example, the nozzles which can be controlled to open and close are respectively arranged on the forward rotation water-containing chamber 411 and the reverse rotation water-containing chamber 412 to realize the jet; or the wall of the lifting rib 40 is provided with a through hole communicated with the water chamber, and the water automatically sprays out through the rotation of the washing drum 20 and the gravity action of the water. In order to simplify the structure, reduce the cost, and increase the reliability of spraying, it is preferable to set the automatic spraying mode using the gravity of water.

Referring to fig. 3, 6 and 7, the lifting rib 40 includes a first cavity wall 42 and a second cavity wall 43 which gradually approach radially inward along the washing drum 20, and a connecting cavity wall 44 which connects the first cavity wall 42 and the second cavity wall 43, as shown in fig. 2, when the washing drum 20 rotates forward, the first cavity wall 42 of the lifting rib 40 first contacts the water surface, that is, when the washing drum rotates forward, the first cavity wall 42 is facing the water surface, and of course, when the first cavity wall 42 also leaves the water surface first. A plurality of first through holes 421 are formed in the first cavity wall 42, and the first through holes 421 are communicated with the positive accommodating water chamber 411 and the accommodating cavity of the washing barrel 2; when the washing drum 20 rotates forward, the first chamber wall 42 is used as a water-facing surface and impacts the water surface at a high speed, so that the washing water enters the forward rotation accommodating water chamber 411 through the first through hole 421; when the first chamber wall 42 leaves the water surface, the first chamber wall 42 is in an inward and upward inclined direction, so that the washing water in the forward rotation accommodating water chamber 411, that is, the first through hole 421 is located at the upper part of the forward rotation accommodating water chamber 411 at this time, and thus the washing water in the forward rotation accommodating water chamber 411 cannot flow out through the first through hole 421; with the first chamber wall 42 in the horizontal state, the washing water in the forward accommodating compartment 411 cannot flow out through the first through hole 421; the washing drum 20 continues to rotate, so that the first cavity wall 42 becomes inclined downwards and inwards, and as the included angle between the first cavity wall 42 and the horizontal plane gradually increases, the washing water in the first cavity wall 42 starts to jet out through the first through hole 421; when the lifting rib 40 reaches the highest point, the washing water in the first chamber wall 42 continues to jet out through the first through hole 421, and impacts the clothes in the washing drum 20.

Referring to fig. 1 and 2, for convenience of description, the position of the lifting rib 40 in the axial direction is according to a center line a-a 'passing through the center of the lifting rib 40 and the axis of the washing cylinder, because the first cavity wall 42 is an arc-shaped surface, and an included angle between a tangent line on the first cavity wall 42 in the radial inward direction of the washing cylinder 20 and the radial direction of the washing cylinder 20 is gradually increased, the time for the plurality of forward rotation water-containing chambers 411 arranged in the lifting rib 40 to start spraying is not uniform, and after the center line a-a' passes through the horizontal plane where the axis of the washing cylinder 20 is located, the liquid level in the forward rotation water-containing chambers 411 starts to be higher than the lowest point of the first through hole 421, so that the forward rotation water-containing chambers 411 start to drip, but only start to be in a dripping state, and the; with the rotation of the washing cylinder 2, the liquid level in the forward rotation water-containing chamber 411 gradually crosses the highest point of the first through hole 421, and the liquid level rises relative to the first through hole 421, and all the forward rotation water-containing chambers 411 reach a spraying state from dripping water; when the lifting rib 40 is located near the highest point, the jet flow rate of the forward accommodating water chamber 411 is the largest. The rotation angle 4131 of the lifting rib from the highest point, that is, the lifting rib 40 reaches the highest point after rotating by an angle β with the washing drum 20, and rotates by an angle β after leaving the highest point; preferably, beta is set to be 10-45 degrees near the highest point, and more preferably, beta is set to be 15-30 degrees near the highest point.

Referring to fig. 4 and 9, when the washing drum 20 is reversed, the second chamber wall 43 of the lifting rib 40 first contacts the water surface, i.e. the second chamber wall 43 is facing the water surface when the washing drum is reversed, and of course, the second chamber wall 43 is first separated from the water surface. A plurality of second through holes 431 are formed in the second cavity wall 43, and the second through holes 431 are communicated with the reverse-rotation accommodating water chamber 412 and the accommodating cavity of the washing drum 2; when the washing drum 20 rotates reversely, the second chamber wall 43 is used as the upstream surface and impacts the water surface at a higher speed, so that the washing water enters the reverse water containing chamber 412 through the second through hole 431, and when the lifting rib 40 reaches the vicinity of the highest point, the washing water in the reverse water containing chamber 412 is jetted and impacted on the washing in the washing drum through the second through hole 431. The jet flow arrangement and principle of the reverse rotation water-containing chamber 412 when the washing drum is rotated in the reverse direction are the same as those of the normal rotation water-containing chamber 411 when the washing drum is rotated in the normal direction, and the description thereof is omitted.

Referring to fig. 8, in the arrangement of the forward rotation water-containing chamber 411 and the reverse rotation water-containing chamber 412 in the water-containing cavity 41, a plurality of first partition plates 413 are arranged in the water-containing cavity 41 at intervals, and the forward rotation water-containing chamber 411 and the reverse rotation water-containing chamber 412 are alternately arranged in the radial direction of the washing drum 20 in the water-containing cavity 41 by the plurality of first partition plates 413; that is, the first partition plates 413 are arranged in parallel in the radial direction, two ends of the first partition plates 413 are respectively connected to the first cavity wall 42 and the second cavity wall 43, and specifically, one end of the first partition plate 413 is fixedly connected to the first cavity wall 42, and the other end of the first partition plate 413 is fixedly connected to the second cavity wall 43. A plurality of water-containing chambers which are arranged in parallel in the radial direction are formed in the water-containing cavity 41 in an interval mode, namely a first partition 413, a first cavity wall 42 and a second cavity wall 43 surround to form a plurality of water-containing chambers, the plurality of water-containing chambers are arranged in a mode that a forward water-containing chamber 411 and a reverse water-containing chamber 412 are alternately arranged, namely a first through hole 421 is formed in the first cavity wall 42, and the water-containing chamber communicated with the first through hole 421 is the forward water-containing chamber 411; the volumes of the forward rotation water-containing chamber 411 and the reverse rotation water-containing chamber 412 are similar to the distribution in the water-containing cavity 41, so that when the washing drum 20 rotates forward and reversely, the water flows respectively sprayed from the forward rotation water-containing chamber 411 and the reverse rotation water-containing chamber 412 are also similar, that is, when the washing drum 20 rotates forward and reversely, the water flows sprayed from the lifting ribs 40 are similar, and both have a large impact effect on clothes.

Referring to fig. 9, in order to ensure a large impact flow rate of the lifting rib 40 near the highest point, the first partition 413 has a first plate portion 4131 and a second plate portion 4132 which gradually approach each other outward in the radial direction of the washing tub 20, and an arc-shaped connecting portion 4133 which connects the first plate portion 4131 and the second plate portion 4132; the first partition 413 is of a bending structure with a convex middle part, so that the forward-rotation water-containing chamber 411 and the reverse-rotation water-containing chamber 412 at the position separated by the first partition 413 are also of bending spaces with convex middle parts, which is beneficial to increasing the distance that the liquid level in the water-containing chamber is higher than the through hole when rotating, and improving the impact force of water flow; the flow of water flow in the water containing chamber is facilitated, and the speed of the water flow during spraying is improved; it is also advantageous to ensure that there is a large water jet when the lifting rib 40 is near the highest point. The angle between the first plate portion 4131 and the second plate portion 4132 is 80 ° to 110 °, and the angle between the first plate portion 4131 and the second plate portion 4132 is preferably 90 ° to 100 °.

Taking the forward rotation as an example, it is described that it is ensured that the lifting rib 40 has a large amount of water flow to be sprayed when being near the highest point, when the lifting rib 40 is at the highest point, because the middle of the first partition 413 is bent outward, a part of liquid in the forward rotation water-accommodating chamber 411 cannot flow out, and must be sprayed after the washing drum 20 continues to rotate and passes through the highest point, so that the flow rate of water flow near the highest point of the washing drum 20 is maximum. And the first plate portion 4131 and the second plate portion 4132 are provided symmetrically.

In the present embodiment, referring to fig. 8, four first partition plates 413 are disposed in the water containing cavity 41 to partition four water containing chambers, and a first reverse rotation water containing chamber 4121, a first forward rotation water containing chamber 4111, a second reverse rotation water containing chamber 4122, and a second forward rotation water containing chamber 4112 are sequentially disposed from inside to outside; in other embodiments, the normal-rotation-accommodating water chamber may be provided from the inside. As for the spacing distance of the plurality of first partitions 413, the plurality of first partitions 413 can be arranged at equal intervals, that is, the distance between two adjacent first partitions 413 is equal; or set so that. In the radial outward direction of the washing drum 20, the intervals between the plurality of first partition plates 413 gradually decrease, and since the first cavity wall 42 and the second cavity wall 43 of the water containing cavity 41 are away from each other in the radial outward direction of the washing drum 20, and in the outward direction, the circumferential size of the four water containing chambers separated by the first partition plates 413 gradually increases, and thus the volumes of the four water containing chambers are not greatly different or are arranged the same by setting the intervals to gradually decrease.

The first inversion water-containing chamber 4121 is formed by the innermost first partition 413, the first chamber wall 42, the second chamber wall 43, and the connecting chamber wall 44 in a surrounding manner, the second through hole 431 communicated with the first inversion water-containing chamber 4121 is formed in the second chamber wall 43, a certain distance is formed between the second through hole 431 and the innermost end of the first inversion water-containing chamber 4121, so that liquid residue can occur in the first inversion water-containing chamber 4121, therefore, the connecting chamber wall 44 is provided with the third through hole 441 for preventing washing water residue in the first inversion water-containing chamber 4121, and the jet flow outlet in the first inversion water-containing chamber 4121 is increased, the size of the third through hole 441 is small, the diameter of the second through hole 431 is 2-5 times of that of the third through hole 441, and the third through hole 441 mainly plays a role in preventing residue.

In this embodiment, referring to fig. 7-9, the lifting rib 40 is a cavity with an open outer side, and the outer ends of the first partition 413 and the first cavity wall 42 are mounted on the inner wall of the washing drum 20, that is, the lifting rib 40 is not located at the bottom of the outer side, which is beneficial to the simple structure and the cost reduction. A plurality of claws 4134 extending outwards are arranged on the first partition 413 at the outermost side, the claws 4134 extend outwards to form the water containing cavity 41, and the claws 4134 are clamped and fixed on the inner wall of the washing drum 20 to realize the installation of the lifting rib 40. Since the first partition 413 is arranged to be convex in the middle, and the first partition 413 and the first chamber wall 42 are far away from each other in the outward direction, the outer space of the outermost first partition 413, if used as a water chamber, has a large volume and a narrow connecting area in the middle, and is not favorable for jet flow; therefore, a second partition 414 is provided in the water containing chamber 41, the second partition 414 is used for arranging the normal-rotation water containing chamber 411 and the reverse-rotation water containing chamber 412 in parallel at intervals in the circumferential direction, and the inner side of the second partition 414 is connected with the outermost first partition 413; that is, the outer side of the second forward rotation water-containing chamber 4112 is further provided with a third forward rotation water-containing chamber 4113 and a third reverse rotation water-containing chamber 4123 which are circumferentially arranged, and a plurality of first partition plates 413 are arranged to partition a radial water-containing chamber, and a second partition plate 414 is arranged to partition a circumferential water-containing chamber; by providing the first and second partition plates 413, 414 in this way, the water containing chamber 41 is partitioned into three normal-rotation water containing chambers 411 and three reverse-rotation water containing chambers 412.

The first through holes 421 are divided into two types, a first forward rotation water-containing chamber 4111 and a second forward rotation water-containing chamber 4112 which are separated from the first partition plates 413 are axially provided with a row of first large through holes 4211, the diameter of each first large through hole 4211 is equal to or slightly smaller than the distance between every two adjacent first partition plates 413, the diameter of each first large through hole 4211 is larger, the jet flow rate can be improved, the impact force on clothes is increased, and the washing water residue in the water-containing chambers is avoided; the jet flow device is also provided with a plurality of rows of first small through holes 4212 which are axially arranged in parallel and communicated with the third positive rotation water-containing chamber 4113, the diameter of the first large through hole 4211 is 1.5-2.5 of the diameter of the first small through hole 4212, the total area of the through holes is increased by arranging the plurality of rows of first small through holes 4212, and the jet flow effect is increased.

The second through holes 431 are divided into two types, the first reverse water-containing chamber 4121 and the second reverse water-containing chamber 4122 separated from the first partition plates 413 are axially provided with a row of second large through holes 4311, the diameter of each second large through hole 4311 is equal to or slightly smaller than the distance between every two adjacent first partition plates 413, and the diameter of each second large through hole 4311 is larger, so that the jet flow rate is favorably improved, the impact force on clothes is increased, and the washing water residue in the water-containing chambers is avoided; the jet flow water heater is also provided with a plurality of rows of second small through holes 4312 which are axially arranged in parallel and communicated with the third reversed water-containing chamber 4123, the diameter of the second large through hole 4311 is 1.5-2.5 of the diameter of the second small through hole 4312, and the total area of the through holes is increased and the jet flow effect is increased by arranging the plurality of rows of second small through holes 4312.
