Description

A flow guiding device for stabilizing the inner drum of a washing machine Technical Field

[0001] This utility model relates to the field of washing machines, and specifically to a flow guiding device for stabilizing the inner drum of a washing machine. Background Technology

[0002] In existing technologies, the inner drum has grooves on its circumference to facilitate external filtration and collection. However, for manufacturers with thinner inner drum walls, this grooved inner drum causes increased deformation during high-speed spin-drying due to the centrifugal force generated by the clothes. This reduces the stability of the washing machine and necessitates manufacturers to design and reduce the inner drum diameter, i.e., reduce the washing volume, in order to achieve a reasonable operating range between the inner and outer drums, resulting in a smaller volume. Technical issues

[0003] In existing technology, the inner drum has a slot and a fluid inlet for collecting shavings and other debris. The fluid inlet extends between the inner and outer drums. Because of the slot, the inner drum is prone to deformation during operation. Due to the size limitations of the door of household drum washing machines, and the fact that the fluid inlet extends between the inner and outer drums, the spacing between the shell, outer drum, and inner drum in existing designs is already narrow. To prevent the inner drum from deforming and colliding with the outer drum, the inner drum diameter must be further reduced, resulting in a significant reduction in washing capacity.

[0004] Due to the large amount of laundry after the inner drum is slotted and the high speed of the spin-drying operation, the centrifugal force generated by the inner drum deformation increases. This causes tension and compression on the large box of the impeller filter collection box and the fixed connection of the lifting ribs of the drum filter collection box. As a result, the fixed ends of the impeller collection box, drum lifting ribs and inner drum installation and disassembly are subject to long-term stress and may become loose. This will affect the smooth disassembly and installation of the filter collection box, which requires users to clean the pollutants in the filter collection box during use.

[0005] Therefore, the aforementioned innovative structural design, which requires the impeller collection box and drum lifting ribs to have an opening on the inner cylinder extending out of the inlet for filtration and collection, can achieve a good user experience while reducing the deformation of the inner cylinder wall caused by the high-speed centrifugal force during dehydration due to the opening. This is key to ensuring the long-term application stability of the product and a smooth and pleasant user experience. Technical solutions

[0055] This utility model provides a flow guiding device for stabilizing the inner drum 3 of a washing machine, including a flow guiding body 1. A through opening 4 is provided on the circumferential surface of the inner drum 3. The flow guiding body 1 is disposed on the inner drum 3 of the washing machine on one side of the opening 4, and the flow guiding body 1 guides the fluid into the opening 4. The flow guiding body 1 is located on the outer circumferential surface of the inner drum 3 of the washing machine.

[0057] The middle connecting part is located on one side of the flow guide body 1 between the first connecting part and the last connecting part;

[0058] The first end connection, the last end connection, and the middle connection of the guide body 1 are all fixedly connected to the inner drum 3 of the washing machine, so that the three sides of the guide body 1 are fixedly connected to the inner drum 3 of the washing machine, thereby increasing the strength of the opening 4 on the inner drum 3 of the washing machine.

[0059] The other side of the flow guide body 1, located between the first end connection and the last end connection, forms a flow guide inlet with the inner drum 3 of the washing machine. The flow guide inlet is connected to the opening 4 through the channel formed by the flow guide body 1 and the inner drum 3 of the washing machine. The structure of the flow guide body 1 is shown in Figure 1.

[0060] In one embodiment, referring to Figure 5, two openings 4 are arranged side by side on the inner drum 3 of the washing machine. The middle connecting part of the guide body 1 corresponding to the two openings 4 is fixedly arranged on the inner drum 3 of the washing machine between the two openings 4, and the guide inlets on the two guide bodies 1 extend in opposite directions. The structure of the guide body 1 is shown in Figures 8-9. It is used to guide the water flow to the openings 4 on the inner drum 3 of the washing machine when the inner drum 3 rotates forward and backward.

[0061] In one embodiment, referring to Figures 3-4, the flow inlet protrudes radially from the outer peripheral surface of the inner drum 3 of the washing machine. Embodiments of the present invention

[0062] In one embodiment, referring to Figures 10-12, it further includes a flow guide seat 7, and the flow guide body 1 is fixedly disposed on the flow guide seat 7 on the side near the opening 4.

[0063] The guide seat 7 is fixedly installed on the outer circumferential surface of the inner drum 3 of the washing machine.

[0064] The guide seat 7 is fixedly connected to the corresponding two ends of the inner drum 3 of the washing machine via a connecting device.

[0065] The connecting device is a connecting plate 6.

When two adjacent guide bodies 1 on the guide seat 7 are located on the same side of the same opening 4, the stability and strength of the inner drum 3 of the washing machine are improved while the guiding effect is enhanced. When two adjacent guide bodies 1 on the guide seat 7 are located on both sides of the same opening 4, it is beneficial to achieve uninterrupted guiding effect when the inner drum 3 of the washing machine rotates forward and backward, and at the same time, it can also improve the strength of the inner drum 3 of the washing machine and prevent it from deforming during operation.

[0069] In one embodiment, referring to Figures 3-7 and 13-17, at least two openings 4 are provided on the inner drum 3 of the washing machine along its axial direction. Two adjacent guide bodies 1 on the guide seat 7 are located on the same side or opposite sides of the adjacent openings 4. When two adjacent guide bodies 1 on the guide seat 7 are located on the same side of the adjacent openings 4, the flow guiding effect is improved while simultaneously enhancing the stability and strength of the inner drum 3. When two adjacent guide bodies 1 on the guide seat 7 are located on opposite sides of the adjacent openings 4, it facilitates uninterrupted flow guiding during the forward and reverse rotation of the inner drum 3, while also improving the strength of the inner drum 3 and preventing deformation during operation.

[0070] In one embodiment, referring to Figures 1, 2, 4, 5, 7-9, 11, 12, 15, and 17, a plurality of reinforcing ribs 2 are fixedly provided on the side of the guide body 1 facing the inner drum 3 of the washing machine. The end of the reinforcing rib 2 away from the guide body 1 crosses the opening 4 and is fixedly connected to the outer peripheral surface of the inner drum 3 of the washing machine, thereby further improving the stability of the inner drum 3 of the washing machine.

[0071] In one embodiment, referring to Figures 3-5, 7, and 17, a plurality of reinforcing arms 5 are provided inside the opening 4. The two ends of the reinforcing arms 5 are fixedly connected to the corresponding side walls of the opening 4, which effectively strengthens the strength of the opening 4 and prevents the inner drum 3 of the washing machine from deforming during operation due to the opening 4.

[0072] In one embodiment, referring to Figures 14-17, the washing machine is a top-loading washing machine. A mounting base is fixedly installed on the inner circumferential surface of the inner drum 3. A collection box 8 is detachably connected to the mounting base, which has a through hole. A fluid inlet 9 is provided on the side of the collection box 8 facing the inner drum. Each fluid inlet 9 is sealed with a one-way opening sealing door 10 that opens due to fluid impact and can automatically close. A collection and filtration device is installed inside the collection box 8. The opening 4 communicates with the fluid inlet 9 through the through hole. The structure of the collection box 8 is shown in Figure 18. If a single opening 4 is provided on the collection box 8 along the circumference of the inner drum 3, the structure of the side of the collection box 8 facing the inner drum 3 is shown in Figure 19. If two openings 4 are provided side-by-side on the collection box 8 along the circumference of the inner drum 3, and the one-way opening sealing doors 10 on the two openings 4 are close to each other on the open end, the structure of the side of the collection box 8 facing the inner drum 3 is shown in Figure 20.

[0073] In one embodiment, referring to Figures 21-23, the washing machine is a drum washing machine. A lifting rib 11 is fixedly provided on the inner circumferential surface of the inner drum 3 of the washing machine. The lifting rib 11 includes an upper part and a lower part. The upper part and the lower part of the lifting rib 11 are detachably connected. The lower part of the lifting rib 11 is fixedly connected to the inner circumferential surface of the inner drum 3 of the washing machine. An opening 12 is provided on the lower part of the lifting rib 11. A fluid inlet 9 is provided on the side of the upper part of the lifting rib 11 facing the inner drum. Each fluid inlet 9 is sealed with a one-way opening sealing door 10 that opens due to fluid impact and can automatically close. A collection and filtration device is provided in the upper part of the lifting rib 11. The opening 4 is connected to the fluid inlet 9 through the opening 12.

[0074] In one embodiment, the side of the guide body 1 corresponding to the middle connecting part extends away from the middle connecting part, and the length of the extension is greater than the width of the opening 4, thereby increasing the contact area between the reinforcing rib 2 and the inner drum 3 of the washing machine and improving the stability of the inner drum 3 of the washing machine. Industrial applicability

[0075] In the above embodiments, the thickness of the present invention is increased as much as possible as needed to ensure the strength of the inner drum 3 of the washing machine, reduce the risk of deformation, effectively prevent the inner drum 3 of the washing machine from touching the outer drum of the washing machine during operation, and ensure that there is a sufficient gap between the inner drum 3 and the outer drum of the washing machine.

[0076] This invention is located at the opening 4. Compared to directly stamping the opening 4 during the production of the inner drum 3 of the washing machine, the uneven stress and uneven force on the steel plate formed during the bending into a cylinder can cause the roundness to be inconsistent, resulting in problems with the automated production line bending into a barrel shape in one go. This invention effectively avoids the occurrence of this problem, thereby reducing the complexity of the process.
