detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Embodiment 1:

In this embodiment, a drum washing machine is taken as an example for detailed description.

As shown in Fig. 1, the washing machine comprises a casing (not shown) in which an outer cylinder 1, an inner cylinder 2 and solid washing particles 3 as a washing medium are disposed. Wherein, the outer cylinder 1 is fixed and not rotated, mainly for holding water, the inner cylinder 2 is used for washing, the inner cylinder 2 is disposed inside the outer cylinder 1, and the inner cylinder 2 is driven to rotate by the driving device, and the inner wall of the inner cylinder 2 A plurality of water passage holes (not shown) for permeable to the washing water are uniformly disposed on the upper portion. The diameter of the water-passing hole is smaller than the minimum diameter of the particle 3, that is, the water-passing hole allows only the washing water to pass through, and the particle 3 cannot pass through the water-passing hole, and the shape of the water-passing hole can be circular, rectangular, polygonal or the like. The washing particles 3 are made of high molecular polymer particles, and a plurality of openings are distributed on the surface of the particles 3, which have strong adsorption properties, and can completely realize the ability of adsorbing dirt to remove a large amount of stains.

A water inlet (not shown) is provided at an upper portion of the outer cylinder 1 for influent water in the washing and rinsing process, and the washing water passes through the water passing hole to enter the inner cylinder 2 for washing, and the lower portion of the outer cylinder 1 is provided with drainage. The mouth (not shown) is used for drainage after dehydration.

On the inner wall of the inner cylinder 2, a plurality of lifting ribs 4 are uniformly disposed along the circumferential direction of the inner wall of the inner cylinder 2, the lifting ribs 4 are disposed along the axial direction of the inner cylinder 2, the lifting ribs 4 are hollow structures, and the washing particles 3 are filled in each The interior of the cavity of the rib 4 is raised. The more the number of lifting ribs 4 and the higher the height, the more the number of particles 3 that can be driven, but the more the number of lifting ribs 4 and the higher the height, the larger the effective volume of the inner cylinder 2 of the washing machine, but The number of the lifting ribs 4 is too small, which in turn affects the effect of the particles 3 adsorbing the dirt. Therefore, in the present embodiment, it is preferable to provide 3-5 lifting ribs 4, and particularly preferably 5 lifting ribs 4.

As shown in Figures 2 and 3, the lifting rib 4 comprises a casing 5 consisting of two side walls 7, two end walls 8 and a top wall 9, and a bottom plate 6 is provided at the bottom of the casing 5, two The side wall 7, the two end walls 8, the top wall 9 and the bottom plate 6 together form a hollow cavity of the lifting rib 4, and the lifting ribs 4 and the particles 3 as a whole can be disassembled for convenient daily maintenance. The side wall 7, the end wall 8 and the top wall 9 are both streamlined, and the two side walls 7 are curved, so that the overall shape of the outer casing 5 is streamlined and has a central symmetrical structure, which is more advantageous. The laundry 14 is tumbling in the inner cylinder 2 to increase the washing rate.

A plurality of water permeable holes 10 are formed in the top wall 9 of the outer casing 5, and a plurality of water permeable holes 10 are also opened in the bottom plate 6.

The bottom plate 6 is a flat plate structure, and the inner wall of the inner tube 2 has an arc structure, and a certain gap exists between the bottom plate 6 and the inner wall of the inner tube 2, which is advantageous for the entry and discharge of the washing water.

During the washing or rinsing process, the washing water in the inner cylinder 2 enters the lifting rib 4 through the water permeable hole 10, so that the washing water contacts the particles 3 in the lifting rib 4, and the granule 3 exerts its strong adsorption property and will be washed down. The dirt is adsorbed and removed, and the pure washing water adsorbed by the particles 3 is discharged from the lifting ribs 4 through the water permeable holes 10.

As shown in Fig. 1, when the lifting rib 4 is at the position A, the washing water in the inner cylinder 2 enters the lifting rib 4 through the water permeable hole 10, and the granule 3 is immersed in the washing water. With the rotation of the inner cylinder 2, the lifting rib 4 When it is transferred to position B, a part of the washing water is stored in the pellet 3, and the pellet 3 adsorbs the dirt. When the lifting rib 4 continues to the position C, the purer washing water after the adsorption passes through the top wall 9 and the bottom plate 6. The water permeable aperture 10 flows back onto the laundry 14, thereby circulating.

The reciprocating cycle of the granules 3 effectively improves the purity of the washing water or the rinsing water during the contact with the clothes 14, and greatly improves the washing rate. In addition, since the particles 3 are always stored in the lifting ribs 4, the spraying and recycling process of the particles 3 is not required, the washing time is reduced, the water consumption is saved, and the laundry 14 and the particles 3 are separated during the washing and rinsing, The problem of separation of the particles 3 from the laundry 14 in the prior art is effectively solved, and the washing time is further shortened.

During the dehydration process, the inner cylinder 2 rotates at a high speed to drive the particles 3 in the lifting rib 4 to rotate at a high speed, and the dirt adhering to the surface of the granule 3 is discharged out of the washing machine together with the washing water by high-speed centrifugal force, thereby realizing the regeneration of the granule 3. The regeneration process is simple and convenient.

The lifting rib 4 is provided with the water permeable hole 10 only on the top wall 9 and the bottom plate 6, which not only simplifies the processing process, but also reduces the processing difficulty. At the same time, the residence time of the washing water in the lifting rib 4 can be appropriately increased, which is advantageous for the granule 3 and the washing water. The contact between the particles 3 allows the particles 3 to better adsorb dirt in the water.

As shown in FIG. 2 and FIG. 3, a flange 11 for fixed mounting is extended to the two sides of the two side walls 7 of the outer casing 5, and a mounting hole 12 is provided on the flange 11 by screws or the like. The fastener passes through the mounting hole 12 to fix the lifting rib 4 to the inner wall of the inner cylinder 2.

When the inner cylinder 2 rotates, the lifting rib 4 is turned to the position B. There is a part of the washing water in the granule 3, and the granule 3 adsorbs the dirt. When the lifting rib 4 continues to the position C, the purer washing water after the adsorption flows back through the permeable hole 10 on the top wall 9 and the bottom plate 6. Waiting for laundry 14 on.

In this step, the rotation speed of the inner cylinder 2 is optimal between 100 and 200 rpm.

Step 3: After the washing is completed, draining is performed, and the washing water is discharged from the drain port below the outer cylinder 1. Step 4: The inner cylinder 2 is rotated at a high speed, and the laundry 14 and the pellets 3 in the inner cylinder 2 are simultaneously dehydrated to regenerate the particles 14, and the washing water is collected in the outer cylinder 1 and discharged from the drain port below the outer cylinder 1.

In this step, the rotational speed of the inner cylinder 2 is operated at a rotational speed of 100-1000 rpm, which is usually higher than the rotational speed at the time of washing.

Step 5: In the rinsing step, the appropriate amount of clean water is added to the outer tube 1. The clothes 14 are rinsed according to the above process, and the above-mentioned dehydration process is performed again after rinsing, and finally the entire washing process of the clothes is completed, and the clothes 14 are taken out and aired.

Embodiment 2:

The difference from the first embodiment is that, as shown in FIG. 4, in the embodiment, the outer surface of the outer casing 5 is disposed. There are a plurality of projections 13. In order to simplify the structure of the lifting ribs 4, only the projections 13 are provided on the top wall 9, and the projections 13 and the outer casing 5 are integrally formed. The projections 13 enhance the friction with the garment 14, making the dirt on the garment 14 more likely to fall off, thereby increasing the cleaning rate.

As described above, a similar technical solution can be derived by combining the contents of the schemes given in the drawings. Any simple modifications, equivalent changes and modifications to the above embodiments in accordance with the technical spirit of the present invention are still within the scope of the technical solutions of the present invention.
