Description

Technical Field

[0001] The invention belongs to the technical field of laundry equipment, and in particular relates to a lifting rib and a washing tub and a washing machine having the same. Background Art

[0002] A drum washing machine is a washing machine designed to imitate the principle of a hammer hitting clothes. The drum washing machine includes an inner drum with lifting ribs. The drum is rotated by the mechanical work of the motor, and the clothes are lifted and dropped in the drum. In this process, the clothes rub against each other and against the drum wall. These actions are repeated continuously as the drum rotates. The combined effect of detergent and water makes the clothes clean.

[0003] Lifting ribs are the core components of washing clothes in drum washing machines. The structure and shape of the lifting ribs determine the intensity of movement and the washing effect of clothes. The lifting ribs not only lift clothes during washing, but also move water to the side. However, most lifting ribs on the market currently have only a simple slope on the side, which makes it easy for clothes to slide when lifting, so that clothes cannot be lifted to a certain height, and the strength when falling and the friction between clothes are weak, which will weaken the washing effect. Summary of the invention

[0004] In view of this, the present invention provides a lifting rib to solve the problems of poor clothing lifting effect and narrow water flow flushing range in the prior art.

[0005] The present invention provides a lifting rib, which is a broken line structure as a whole, and comprises:

[0006] A top portion extending along the fold line structure and having concave portions and convex portions formed at the corners of the fold line structure;

[0007] The bottom portion is used to fix the lifting ribs to the inner wall of the washing tub;

[0008] The left and right side surfaces are formed on the left and right sides between the top and the bottom, and both the left and right side surfaces are formed with concave surfaces and convex surfaces. On any side surface of the left or right side surface, the position of the concave surface corresponds to the position of the concave portion on its side, and the position of the convex surface corresponds to the position of the convex portion on its side.

[0009] Further optionally, an inner cavity is formed inside the lifting rib, a first water hole communicating with the inner cavity is formed at the top, and a second water hole communicating with the inner cavity is formed at the concave surfaces of the left and right side surfaces.

[0010] Further optionally, the lifting rib is narrow at the top and wide at the bottom, and the left and right side surfaces are tilted toward the top as a whole.

[0011] Further optionally, on any side surface of the left or right side surface, the concave surface position corresponds to the concave portion position on that side, and the convex surface position corresponds to the convex portion position on that side.

[0012] Further optionally, the concave surface includes a first concave surface and a second concave surface, and the convex surface includes a first convex surface and a second convex surface; the right side surface is composed of the first concave surface and the first convex surface; the left side surface is composed of the second concave surface and the second convex surface; the first concave surface and the second convex surface are arranged opposite to each other on both sides of the top; the first convex surface and the second concave surface are arranged opposite to each other on both sides of the top; the first concave surface and the second concave surface are arranged diagonally opposite to each other on both sides of the top; the first convex surface and the second convex surface are arranged diagonally opposite to each other on both sides of the top.

[0013] Further optionally, both the first concave surface and the second concave surface have multiple rows of second water holes, and the multiple rows of second water holes are arranged along the first concave surface or the second concave surface, and the multiple rows of second water holes are generally arranged obliquely downward.

[0014] Further optionally, the first water hole arranged at the top is arranged along the top.

[0015] Further optionally, the inner cavity of the lifting rib has a lifting rib mounting hole and a buckle; the lifting rib mounting hole is used for fixing the lifting rib; and the buckle is used for positioning the lifting rib.

[0018] The present invention also provides a washing machine provided with the above-mentioned washing tub or the above-mentioned lifting ribs.

[0019] The present invention optimizes the structure and shape of the lifting ribs, and the overall structure is a broken line structure. The side surface of the structure is composed of a concave surface and a convex surface. The concave surface is used to lift clothes, and the convex surface is used to stir the water flow, thereby improving the lifting effect of clothes and directing the water flow to both sides to flush the door seal and the bottom of the inner drum of the washing machine, thereby expanding the flushing range of the water flow.

[0035] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0036] The lifting ribs provided by the present invention are of a folded line structure as a whole, and their side surfaces are composed of a convex surface and a concave surface. The convex surface can divert water to both sides to clean the door seal and the bottom of the inner drum of the washing machine; the concave surface is provided with a water hole for water to flow through, thereby reducing the running resistance and reducing the pressure for lifting clothes.

[0037] like Figure 1 and Figure 2 As shown, the lifting ribs provided in this embodiment include a top 2, a bottom, a left side 12 and a right side 11, the top 2 extends along the folded line structure, and a concave portion 41 and a convex portion 42 are formed at the corners of the folded line structure; the bottom is used to fix the lifting ribs on the inner wall of the washing tub 6; the left and right sides are formed on the left and right sides between the top 2 and the bottom, and the left and right sides are both composed of a concave surface and a convex surface.

[0038] Preferably, the lifting rib is narrow at the top 2 and wide at the bottom, and the left and right sides are tilted toward the top 2 as a whole, to ensure that the lifting rib is reliably connected to the inner wall of the washing tub 6 and has a certain strength to lift clothes.

[0039] Preferably, an inner cavity is formed inside the lifting rib, and a first water hole 24 connected to the inner cavity 5 of the lifting rib is formed on the top 2, and the first water hole 24 is arranged along the top 2. The water entering the inner cavity 5 of the lifting rib flows out to the first water hole 24 and is sparsely distributed. It has a certain pressure, which impacts the clothes to achieve the washing effect.

[0040] Preferably, the concave surfaces of the left and right sides are formed with second water holes 13 communicating with the inner cavity 5 of the lifting ribs, and multiple rows of second water holes 13 are arranged along the concave surface, and the multiple rows of second water holes 13 are arranged obliquely downward as a whole. Specifically, the second water holes 13 are equal-diameter water holes and are perpendicular to the bottom surface. When the washing tub 6 rotates, water flows to the second water holes 13 and enters the interior of the lifting ribs, and a part of it flows out from the second water holes 13; the second water holes 13 are densely distributed, which is convenient for water to flow through when lifting clothes, reducing the operating pressure.

[0041] Preferably, the concave surface includes a first concave surface 112 and a second concave surface 121, and the convex surface includes a first convex surface 111 and a second convex surface 122; thus, on the one hand, the concave surface can be used to lift the clothes to a higher place to improve the effect of washing clothes; on the other hand, the convex surface can be used to push the water flow away to expand the flushing range of the water flow to the washing barrel.

[0042] Preferably, the right side surface 11 is composed of a first concave surface 112 and a first convex surface 111; the left side surface 12 is composed of a second concave surface 121 and a second convex surface 122; the first concave surface 112 and the second convex surface 122 are arranged opposite to each other on both sides of the top 2; the first convex surface 111 and the second concave surface 121 are arranged opposite to each other on both sides of the top 2; the first concave surface 112 and the second concave surface 121 are arranged diagonally opposite to each other on both sides of the top 2; the first convex surface 111 and the second convex surface 122 are arranged diagonally opposite to each other on both sides of the top 2.

[0043] Preferably, the lifting rib further includes an end portion 3 , including a first end portion 31 and a second end portion 32 ; the top portion 2 , the side surface 1 , the first end portion 31 , and the second end portion 32 form a lifting rib inner cavity 5 .

[0044] Preferably, the lifting rib has a concave portion 41 and a convex portion 42; on either the left or right side surface, the position of the concave surface corresponds to the position of the concave portion 41 on that side, and the position of the convex surface corresponds to the position of the convex portion 42 on that side.

[0045] Preferably, the first concave surface 112 or the second convex surface 122 has the largest curvature at the concave portion 41; the first convex surface 111 or the second concave surface 121 has the largest curvature at the convex portion 42; a larger concave curvature value can lift more clothes, and a larger convex curvature value can move more water.

[0046] Preferably, the top 2 consists of a first top 21, a middle top 23 and a second top 22; the width of the first top 21 gradually increases from the first end 31 to the recess 41; the width of the second top 22 gradually increases from the second end 32 to the convex 42; the width of the middle top 23 from the recess 41 to the convex 42 remains unchanged; the middle top 23 has a large width, which ensures the lifting strength and has a good effect of lifting clothes.

[0047] Preferably, the overall structure of the lifting ribs is a broken line type, and more preferably, is centrally symmetrical with a narrow top 2 and a wide bottom, thereby further improving the washing effect.

[0048] Preferably, the inner cavity of the lifting rib has a lifting rib mounting hole 51, a buckle 52 and a reinforcing rib 53; the lifting rib mounting hole 51 is used to install the lifting rib on the washing bucket 6; the buckle 52 is used to position the lifting rib; the reinforcing rib 53 is perpendicular to the bottom surface and the top surface, and the reinforcing rib 53 is arranged between the recessed portion 41 and the convex portion 42 to strengthen the strength of the lifting rib. A trapezoidal groove is left in the middle of the reinforcing rib 53 to facilitate the flow of water inside the lifting rib, thereby ensuring that the lifting rib can lift a certain amount of clothes.

[0049] Specifically, the curvature of the side surface of the lifting rib has the following rules:

[0050] ① The curvature gradually increases from the first end portion 31 of the lifting rib to the concave portion 41, and reaches the maximum curvature at the concave portion 41, so that an obvious first concave surface 112 is formed;

[0051] ② The curvature gradually decreases from the concave portion 41 to the middle of the lifting rib, until the curvature reaches the minimum in the middle of the lifting rib;

[0052] At this time, the curvature of the first end portion 31 is equal to the curvature of the middle portion of the lifting rib;

[0053] ③ The curvature of the lifting rib increases from the middle of the lifting rib to the convex portion 42, and reaches the maximum curvature at the convex portion 42, so that an obvious first convex surface 111 is formed;

[0054] ④ The curvature gradually decreases from the convex portion 42 to the second end portion 32 until the curvature of the second end portion 32 reaches the minimum;

[0055] At this time, the curvature of the second end portion 32 is equal to the curvature of the middle portion of the lifting rib.

[0056] The washing machine provided by the present invention has a washing tub provided with the above-mentioned lifting ribs; the lifting ribs are fixed to the inner wall of the washing tub by screws, and a plurality of them are arranged in a circular pattern, so that the effect of lifting clothes by the washing machine is improved and the water flow cleaning range is expanded.

[0057] like Figure 3As shown, the washing bucket of this embodiment has a washing bucket mounting hole 61 and a slot 62; the slot 62 and the buckle 52 cooperate to position the lifting rib; the washing bucket mounting hole 61 and the lifting rib mounting hole 51 cooperate to fix the lifting rib on the washing bucket 6; the lifting rib is arranged on the washing bucket 6 in a circular pattern.

[0058] The lifting ribs realize the function of lifting and washing clothes in the following manner: when the washing machine rotates forward, the second concave surface 121 is used to lift the clothes. At this time, water can enter the lifting rib inner cavity 5 from the second water hole 13 at the second concave surface 121. On the one hand, the water flows out from the second water hole 13 at the first concave surface 112 to reduce the operating pressure, and on the other hand, it is sprayed out from the first water hole 24 to spray onto the clothes to increase the washing effect of the clothes; the second convex surface 122 pushes the water in the washing tub 6 to the door seal to wash away the foam at the door seal;

[0059] When the washing machine is reversed, the first concave surface 112 is used to lift the clothes. At this time, water can enter the inner cavity 5 of the lifting rib from the second water hole 13 on the first concave surface 112. On the one hand, the water flows out from the second water hole 13 on the second concave surface 112 to reduce the operating pressure. On the other hand, the water is sprayed out from the first water hole 24 to the clothes, thereby increasing the washing effect of the clothes. The first convex surface 111 pushes the water in the washing tub 6 to the door seal to rinse the foam at the door seal.
