Description

Technical Field

[0001] The utility model relates to the technical field of down processing, in particular to a down pre-washing washing machine. Background Art

[0002] As people's living standards improve, consumers have increasingly high expectations for the quality of down products. They demand not only good warmth retention but also a soft, comfortable feel. Clean, fluffy down is key to ensuring the quality of down products. This requires the use of specialized down pre-washing machines to deeply clean the down, removing impurities and odors, and improving its fluffiness and softness. Traditional down washing methods can generate large amounts of wastewater containing pollutants such as detergents, grease, and impurities. Direct discharge without treatment can cause serious environmental pollution. Down pre-washing machines can optimize the cleaning process, reduce detergent usage, and, equipped with efficient wastewater treatment systems, reduce wastewater discharge and pollutant concentrations, meeting environmental protection requirements.

[0003] However, existing technologies have the following shortcomings: Down is light and fluffy, and during the pre-wash process, the down is easily moved by the water flow and gathered around the filter cartridge, causing some fine down fibers to enter the filter pores. As the washing process progresses, more and more fibers accumulate in the filter pores, gradually clogging them. Furthermore, during the pre-wash process, the continuous flow of the cleaning liquid may carry down and impurities into the filter cartridge. If the filtration speed cannot keep up with the impurity accumulation speed brought by the water flow, the filter pores can easily become clogged. Therefore, those skilled in the art have provided a down pre-washing washing machine to address the above-mentioned problems. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 - Figure 5 A down pre-washing washing machine includes a pre-washing water tank 1, a feed port 4, a driving motor 3, a pre-washing chamber 20, a transmission plate 12, a crank 18, a driving rod 17, an indirect rotating tooth 13, a fixing plate 19, a dredging mechanism, a fixing frame 7, a filter cartridge 10, a connecting frame 8, a centrifugal disc 9, a fixing block 5, a support seat 2, a liquid inlet 6 and a drain outlet 11.

[0030] In practice, down to be pre-washed is fed into the pre-wash chamber 20 of the pre-wash water tank 1 through the feed port 4. Simultaneously, an appropriate amount of cleaning liquid is injected into the pre-wash water tank 1 through the liquid inlet 6. The drive motor 3 is activated, and its output drives the rotating rod, which in turn rotates the transmission disc 12 located in the middle and right side of the inner wall of the pre-wash chamber 20, thereby driving the crank 18. The drive rod 17, located in the middle and upper end of the left side wall of the crank 18, undergoes periodic motion in response to the movement of the crank 18. Because the drive rod 17 indirectly meshes with the indirect rotating gear 13, the indirect rotating gear 13 intermittently rotates in the middle and upper end of the left side wall of the pre-wash chamber 20.

[0031] The fixed plate 19 at the rear middle position of the left side wall of the indirect rotating tooth 13 also rotates intermittently, thereby driving the dredging mechanism installed at the rear middle position of the left side wall of the fixed plate 19 to move. The connecting plate 14 in the dredging mechanism performs intermittent circular motion along with the fixed plate 19. During the movement of the several reset springs 15 and cleaning balls 16 on the connecting plate 14, when the connecting plate 14 approaches the filter cartridge 10, the cleaning balls 16 overcome the pulling force of the reset springs 15 under the action of centrifugal force and move outward, contacting the filter holes opened on the outer wall of the filter cartridge 10. Since each cleaning ball 16 matches the filter hole, the cleaning ball 16 can clean the materials and impurities accumulated in the filter hole to prevent the filter hole from being blocked. When the connecting plate 14 moves away from the filter cartridge 10, the reset spring 15 pulls the cleaning ball 16 back, making it closer to the connecting plate 14.

[0032] A fixed frame 7 is mounted in the center, on the left side, of the inner wall of the pre-wash chamber 20. A filter cartridge 10 is mounted in the center, on the outer side, of the right side wall of the fixed frame 7. A connecting frame 8 is mounted at the other end of the filter cartridge 10. During the pre-wash process, the down and impurities are filtered by the water flow, with some impurities being filtered by the filter cartridge 10. A centrifugal disk 9, rotatably connected to the center of the inner wall of the connecting frame 8, is driven by a rotating rod. The high-speed rotation of the centrifugal disk 9 generates centrifugal force, causing the down to tumble and move continuously within the pre-wash chamber 20, enhancing the cleaning effect while also pushing impurities toward the filter cartridge 10, improving filtration efficiency.

[0033] After cleaning is completed, the sewage can be discharged from the drain port 11. Fixed blocks 5 are installed in the middle of the front side wall and the middle of the rear side wall of the pre-wash water tank 1. The two fixed blocks 5 are distributed in mirror image. A support base 2 is installed at the bottom to support the entire down pre-wash washing machine to ensure the stability of the equipment.

[0034] Through the above embodiments, the down pre-washing and washing machine can effectively pre-wash the down, improve the cleaning effect, and avoid clogging of the filter holes, thereby ensuring the stable operation of the equipment.

[0035] Working principle: Start the drive motor 3, and the output end of the drive motor 3 drives the rotating rod to rotate, and the transmission plate 12 on the outside of the rotating rod located in the middle of the inner wall of the pre-wash chamber 20 on the right side rotates accordingly, thereby driving the crank 18 to rotate, and the drive rod 17 in the middle of the upper end of the left side wall of the crank 18 moves with the rotation of the crank 18. Since the drive rod 17 is indirectly engaged with the indirect rotating tooth 13, the indirect rotating tooth 13 rotates intermittently in the middle of the upper end of the left side wall of the pre-wash chamber 20, and the fixed plate 19 in the middle of the left side wall of the indirect rotating tooth 13 rotates intermittently, thereby driving the dredging mechanism installed in the middle of the left side wall of the fixed plate 19 on the rear side to move. The centrifugal disk 9 is driven to rotate by the rotating rod. During the pre-washing process, the centrifugal disk 9 rotates at high speed to generate centrifugal force. This centrifugal force can make the down constantly roll and move in the pre-wash chamber 20, so that the down is fully in contact with the cleaning liquid, thereby enhancing the cleaning effect. Compared with simple immersion cleaning, the centrifugal effect can make all parts of the down be flushed by the cleaning liquid, thereby improving the uniformity and thoroughness of the cleaning.

[0036] The pre-wash chamber 20 rotates, and the transmission plate 12 on the outer side of the rotating rod located in the middle and right side of the inner wall of the pre-wash chamber 20 rotates accordingly, thereby driving the crank 18 to rotate. The drive rod 17 located in the middle and upper end of the left side wall of the crank 18 moves with the rotation of the crank 18. Because the drive rod 17 indirectly engages with the indirect rotating gear 13, the indirect rotating gear 13 intermittently rotates in the middle and upper end of the left side wall of the pre-wash chamber 20. The fixed plate 19 located in the middle and rear end of the left side wall of the indirect rotating gear 13 also rotates intermittently, thereby driving the dredging mechanism installed in the middle and rear end of the left side wall of the fixed plate 19. The centrifugal disk 9 is driven by the rotating rod to rotate. During the pre-wash process, the centrifugal disk 9 rotates at high speed to generate centrifugal force. This centrifugal force causes the down to continuously tumble and move in the pre-wash chamber 20, allowing the down to fully contact the cleaning liquid, thereby enhancing the cleaning effect. Compared with simple immersion cleaning, the centrifugal action can ensure that all parts of the down are flushed by the cleaning liquid, improving the uniformity and thoroughness of the cleaning.

[0037] The movement of the dredging mechanism is indirectly driven by the drive motor 3. Once the drive motor 3 is activated, a series of transmissions causes the fixed plate 19 to intermittently rotate, thereby driving the movement of the connecting plate 14. Initially, the cleaning ball 16, under the action of the return spring 15, is positioned relatively close to the connecting plate 14. As the fixed plate 19 intermittently rotates with the indirect rotating teeth 13, the connecting plate 14 also performs a circular motion. Due to the intermittent rotation of the fixed plate 19, the movement path of the connecting plate 14 is an intermittent circular motion. As the connecting plate 14 moves, the cleaning ball 16, under the combined action of centrifugal force and the return spring 15, moves along the outer wall of the filter cartridge 10. When the connecting plate 14 is close to the filter cartridge 10, the cleaning ball 16 overcomes the pulling force of the return spring 15 and moves outward under the action of centrifugal force, and contacts the filter holes opened on the outer wall of the filter cartridge 10; when the connecting plate 14 is away from the filter cartridge 10, the return spring 15 pulls the cleaning ball 16 back and makes it close to the connecting plate 14. During the movement of the cleaning ball 16, since it matches the filter holes on the outer wall of the filter cartridge 10, when the cleaning ball 16 contacts the filter holes, it can push out the materials and impurities accumulated in the filter holes to prevent the filter holes from being blocked. The function of the return spring 15 is, on the one hand, to pull the cleaning ball 16 back when the connecting plate 14 is away from the filter cartridge 10, and on the other hand, it can also make the cleaning ball 16 have a certain elastic pressure when it contacts the filter holes, thereby ensuring the cleaning effect.

[0038] After cleaning is completed, the sewage can be discharged from the drain outlet 11. Fixed blocks 5 are installed in the middle position of the front side wall and the middle position of the rear side wall of the pre-wash water tank 1. The two fixed blocks 5 are distributed in mirror-image opposition. A support base 2 is installed at the bottom to support the entire down pre-wash washing machine to ensure the stability of the equipment.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
