[0039] The washing machine is a cleaning appliance that uses electric energy to produce mechanical action to wash clothes. The inner barrel of the pulsator washing machine is provided with a circular pulsator with protruding paddles on the surface. Under the driving of the pulsator, the water flow in the barrel forms a vortex that rotates right and left at times, driving the fabric to rotate and tumble, so that the stains on the clothes can be washed. Generally, the pulsator washing machine will have the phenomenon of clothes floating in the initial stage of washing clothes such as down, wool, silk, etc. The floating area is not in contact with water and detergent, so the clothes cannot be washed better in the washing process, and the washing is not in place, resulting in poor washing.
[0040] The washing equipment provided by the embodiments of the present application solves the problem of poor washing effect of the existing washing equipment. The following will be described in combination with the accompanying drawings Figures 1-6 The arrow direction in the figure is the water flow direction.
[0041] The washing equipment provided by the embodiments of the present application, as shown in Figures 1-3 The washing equipment provided by the embodiments of the present application, as shown in
[0042] It can be understood that there is a gap between the inner barrel 100 and the outer barrel 200, which provides the necessary space for the rotation of the inner barrel 100. At the same time, the gap and the internal space of the inner barrel 100 are mutually communicable, that is, the water in the inner barrel 100 can flow into the gap between the inner barrel 100 and the outer barrel 200. When the inner barrel 100 rotates, the water in the gap can rotate together, and under the action of centrifugal force, it rises to the annular cover 300, and under the water guiding action of the water guide groove 301 of the annular cover 300, it is sprayed from above the inner barrel 100 to the clothes, thereby realizing efficient wetting, ensuring that the clothes are evenly and fully wetted during the washing process, reducing the possibility of clothes floating, and because the clothes are fully penetrated by water, the detergent can more effectively enter the fibers, thereby improving the washing degree.
[0043] Further, the width of the water guide groove 301 gradually decreases from the edge to the center, which not only helps to accelerate the water flow, but also enhances the jetting force of the water flow, ensuring that the clothes can be more fully contacted with water and detergent during the washing process, and further improving the washing effect of the clothes.
[0044] In an optional embodiment, referring to Figure 3As shown, the outer ring of the annular cover 300 is provided with a first surrounding plate 340, and the annular cover 300 is alternately provided with a plurality of first water guide ribs 310 and second water guide ribs 320 in the circumferential direction, and the first water guide ribs 310, the second water guide ribs 320 and the first surrounding plate 340 form a water guide groove 301.
[0045] Exemplarily, the first surrounding plate 340 can be a layer of thin plate arranged outside the annular cover 300, for example, the first surrounding plate 340 can be perpendicular to the annular cover 300 to block the water in the gap between the outer cylinder 200 and the inner cylinder 100 from flowing out of the washing equipment. The first surrounding plate 340 can be integrally formed with the annular cover 300 to improve the structural strength and facilitate processing, without the need for assembly, and to ensure good sealing performance.
[0046] One end of the first water guide rib 310 and the second water guide rib 320 can be connected with the first surrounding plate 340, and the other end extends to the center of the annular cover 300 to form the water guide groove 301 for collecting and guiding the water flow. The water guide groove 301 is provided with an opening, and the water flowing out of the opening can fall into the inner cylinder 100 through the central hole in the center of the annular cover 300 to wet the clothes, reducing the floating phenomenon of the clothes during the washing process.
[0047] In an optional embodiment, in combination with Figure 4 and Figure 5 As shown, the outer ring of the annular cover 300 is provided with a water guide arc surface 302, and the height of the outer side of the water guide arc surface 302 is lower than the height of the inner side of the water guide arc surface 302.
[0048] In this embodiment, when the inner cylinder 100 rotates to generate a centrifugal force to make the water flow in the gap rise, the design of the water guide arc surface 302 can smoothly adjust the movement direction of the water flow from vertical or oblique to horizontal, reducing the resistance of the water flow during movement. By adjusting the direction of the water flow to be horizontal, the water guide arc surface 302 reduces the energy loss of the water flow during the rising process, so that the water flow can move to the water guide groove 301 with higher speed and more stable flow direction.
[0049] The water flow in the horizontal direction can be more smoothly sprayed out of the opening when reaching the water guide groove 301, uniformly covering the clothes in the inner cylinder 100, thereby improving the wetting degree of the clothes and the washing effect. At the same time, the water guide arc surface 302 reduces the resistance of the water flow during movement, the speed of the water flow is improved, and the spraying force of the water flow is enhanced, so that the clothes can be wetted more and better, the entanglement and floating phenomenon of the clothes during the washing process is reduced, and it is ensured that the clothes can be fully washed, improving the washing effect.
[0050] In an optional embodiment, in combination with Figure 3As shown, the first water guide rib 310 and the second water guide rib 320 are both arc-shaped, and the arc of the first water guide rib 310 is greater than that of the second water guide rib 320. The arc-shaped first water guide rib 310 and the second water guide rib 320 can smoothly guide the water flow, reduce the resistance of the water flow when moving in the water guide groove 301, and thus improve the flow rate and the spraying force of the water flow. Moreover, the arc of the first water guide rib 310 is greater than that of the second water guide rib 320, so that the channel width of the water flow gradually decreases when passing through the water guide groove 301, and the water flow has a stronger impact force when being sprayed, thereby more effectively wetting and cleaning the clothes.
[0051] In an optional embodiment, referring to Figure 3 As shown, the side of the first water guide rib 310 connected with the first surrounding plate 340 is provided with an arc-shaped water guide portion 306, so that the water flow can be smoothly transitioned, avoiding energy loss caused by sudden change of the water flow direction and reducing the resistance. Optionally, the slope of the arc-shaped water guide portion 306 provides a smooth transition path for the rising water flow, so that the water flow can more smoothly enter the water guide arc surface 302 and the water guide groove 301.
[0052] In an optional embodiment, in combination with Figure 4 and Figure 5 As shown, the side of the first surrounding plate 340 away from the water guide groove 301 is provided with a second surrounding plate 350, and the second surrounding plate 350 and the first surrounding plate 340 define a mounting groove 303 in which the outer cylinder 200 is inserted. When installing the ring-shaped cylinder cover 300 and the outer cylinder 200, the ring-shaped cylinder cover 300 is only needed to be aligned with the outer cylinder 200, and the outer cylinder 200 is inserted into the mounting groove 303 to realize positioning of the ring-shaped cylinder cover 300, facilitating installation. At the same time, the water flow in the gap between the inner cylinder 100 and the outer cylinder 200 is avoided.
[0053] In an optional embodiment, referring to Figure 1 As shown, the ring-shaped cylinder cover 300 is provided with a plurality of mounting holes 304 circumferentially, and the ring-shaped cylinder cover 300 is connected with the outer cylinder 200 through the mounting holes 304 to realize uniform stress distribution. For example, the cylinder cover can be fixed on the outer cylinder 200 through fasteners such as bolts to realize firm connection of the ring-shaped cylinder cover 300 and the outer cylinder 200, improve the overall structural stability of the washing equipment, and the bolt connection mode is convenient for disassembly, facilitating maintenance and replacement.
[0054] In an optional embodiment, referring to Figure 1 and Figure 3 As shown, the ring-shaped cylinder cover 300 is provided with a plurality of first clamping portions 305 circumferentially, and the outer cylinder 200 is provided with a plurality of second clamping portions 202 circumferentially. When the ring-shaped cylinder cover 300 is installed on the outer cylinder 200, the first clamping portions 305 and the second clamping portions 202 are clamped.
[0055] The first snap-fit portion 305 can be a groove, a protrusion, or other shape that enables the snap-fit function. The second snap-fit portion 202 matches the shape of the first snap-fit portion 305. Multiple snap-fit portions can be evenly distributed along the circumference to ensure that the annular cover 300 is evenly stressed during installation. The snap-fit structure simplifies the assembly process of the annular cover 300 and the outer cylinder 200, and also facilitates installation and disassembly.
[0056] In one alternative implementation, refer to Figure 3 As shown, a third water guide rib 330 is connected between the first water guide rib 310 and the second water guide rib 320 corresponding to the adjacent water guide groove 301. The third water guide rib 330 is located on the side of the water guide groove 301 away from the first enclosure 340. The third water guide rib 330 serves as a reinforcing rib on the one hand, and guides the water flow here to fall into the inner drum 100 in a "curtain" state to wet the clothes. It can wet the clothes in the inner drum 100 in a full range, ensuring that the clothes in the inner drum 100 are fully and evenly wetted.
[0057] In one optional embodiment, the first water guide rib 310 is integrally formed with the annular cap 300; and / or, the second water guide rib 320 is integrally formed with the annular cap 300, ensuring that the connection between the first water guide rib 310 and the second water guide rib 320 and the annular cap 300 is more secure and less likely to fall off or be damaged.
[0058] Optionally, the third water guide rib 330 can also be integrally formed with the annular cylindrical cover 300, or the first water guide rib 310, the second water guide rib 320 and the third water guide rib 330 can be a single integrated structure, which facilitates processing.
[0059] In one alternative implementation, refer to Figure 6 As shown, the outer wall of the inner cylinder 100 is provided with a first water-lifting rib 101. The first water-lifting rib 101 can be a protruding structure along the outer wall of the inner cylinder 100, with one end of the first water-lifting rib 101 being higher than the other end. It is configured to lift the water between the outer cylinder 200 and the inner cylinder 100 to a preset height when the inner cylinder 100 rotates. When the inner cylinder 100 rotates, the first water-lifting rib 101 can lift the water to the height of the annular cover 300, thereby guiding the water into the water guide groove 301 of the annular cover 300.
[0060] In an optional embodiment, the inner wall of the outer cylinder 200 is provided with a second water-lifting rib 201, the height of one end of the second water-lifting rib 201 being higher than the height of the other end, configured to lift the water between the outer cylinder 200 and the inner cylinder 100 to a preset height when the inner cylinder 100 rotates.
[0061] Optionally, the first water lifting ribs 101 and the second water lifting ribs 201 can be multiple in number and are arranged at intervals along the circumferential direction of the washing machine, so as to further improve the water lifting effect.
[0062] Optionally, the first water lifting ribs 101 can be multiple in number and are arranged at intervals along the circumferential direction of the outer wall of the inner drum 100, so as to further improve the water lifting effect, and multiple rows of the first water lifting ribs 101 can be arranged at intervals along the height direction of the inner drum 100, so as to further improve the water lifting effect. The arrangement of the second water lifting ribs 201 can refer to the arrangement of the first water lifting ribs 101, and the first water lifting ribs 101 and the second water lifting ribs 201 can be arranged alternately, which will not be described herein.
[0063] In an optional embodiment, referring to Figure 4 As shown in the figure, the bottom of the outer drum 200 is provided with a water guide slope 203, which can be inclined towards the center of the inner part of the outer drum 200, so that the water flow can be more effectively guided to move upwards along the slope during the rotation of the inner drum 100, which is conducive to lifting the water in the gap between the inner drum 100 and the outer drum 200 to the upper part of the inner drum 100, so as to ensure that the water can fully contact and penetrate into the clothes, thereby enhancing the washing effect.
[0064] The washing device provided by the embodiment of the present application comprises an inner drum 100, an outer drum 200 and a ring-shaped drum cover 300. The outer drum 200 is arranged outside the inner drum 100, and the ring-shaped drum cover 300 is installed on the outer drum 200. The ring-shaped drum cover 300 is provided with at least one water guide groove 301 extending from the edge to the center of the ring-shaped drum cover 300, and the width of the water guide groove 301 gradually decreases along the extension direction of the water guide groove 301. By arranging the water guide groove 301 extending from the edge to the center of the ring-shaped drum cover 300, the collected water flow can be sprayed from above into the inner drum 100 to wet the clothes, so as to avoid floating. Moreover, the width of the water guide groove 301 gradually decreases, which is conducive to accelerating the water flow speed, enhancing the spraying effect, ensuring that the clothes can fully contact with water and detergent during the washing process, and improving the washing effect of the clothes.
