Household fully automatic dishwashers are only suitable for home use and mainly include cabinet type, countertop type, sink-integrated type, and integrated type.

[0003] Publication number CN211355309U mentions a dishwasher with a siphon drainage structure. By setting up a drainage mechanism, the wastewater entering the drain cylinder is quickly discharged into the drain pipe through the siphon principle using a drain cylinder and a siphon pipe. The drain cylinder stores water at a height higher than the drain hole, thus preventing odor gases from the drain pipe from entering the dishwasher and ensuring its cleanliness. However, when filtering wastewater, waste residue easily clogs the filter screen, resulting in poor water filtration performance and requiring frequent filter cleaning, which is inconvenient to use.

Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a drain structure for an anti-clogging dishwasher, including an upper drain shell 1, a lower drain shell 2, a drive motor 3, a drive gear 4, and an anti-clogging drain mechanism 5. The lower drain shell 2 is installed at the lower end of the upper drain shell 1. An external drive gear 11 is fixed on the circumferential surface of the upper drain shell 1, and an internal transmission gear 12 is fixed on the inner circumferential surface of the upper drain shell 1. The drive motor 3 is installed at the side end of the upper drain shell 1, and the drive gear 4 is installed on the upper surface of the drive motor 3. The anti-clogging drain mechanism 5 is installed inside the upper drain shell 1 and the lower drain shell 2. The anti-clogging drain mechanism 5 includes a drain plate 51, a central support 52, a scraper 53, a cleaning motor 54, a cleaning worm gear 55, a dirt collection box 56, and a cleaning... The design includes a sludge cylinder 57 and a sludge removal bracket 58. A drain plate 51 is installed at the top of the lower drain housing 2. A central support column 52 is installed on the upper surface of the drain plate 51. Two scraper blades 53 are installed on the circumferential surface of the central support column 52. A sludge removal motor 54 is installed at the top of the central support column 52. A sludge removal worm gear 55 is installed on the lower surface of the drain plate 51. A sludge collection box 56 is installed inside the lower drain housing 2. A sludge removal bracket 58 is installed on the circumferential surface of the sludge removal worm gear 55. A sludge removal cylinder 57 is installed on the upper surface of the sludge removal bracket 58. This design solves the problem that in the original device, waste residue easily clogs the filter screen when filtering sewage, leading to poor water filtration performance and requiring frequent cleaning, making it inconvenient to use.

[0020] As the first embodiment of this utility model: the drive motor 3 and the lower drainage shell 2 are fixedly connected by a motor bracket 31. The drive motor 3 and the drive gear 4 are connected by a motor shaft. The drive gear 4 meshes with the external drive gear 11. A scraper driven rack 531 is installed on the outer end face of the scraper 53. The scraper driven rack 531 meshes with the internal transmission gear 12. The width of the scraper 53 is the same as the radius of the drainage plate 51. The drainage plate 51 is three-quarter disc shaped. A scraper motor shaft 541 is installed on the lower surface of the cleaning motor 54. The cleaning motor 54 is fixedly connected to the central support column 52. The scraper motor shaft 541 passes through the lower surface of the central support column 52 and the surface of the drainage plate 51. The scraper motor shaft 541 is connected to the scraper worm 55. Several drainage holes 511 are opened on the surface of the drainage plate 51. The scraper bracket 58 and the scraper worm 55 are meshed with each other by threads. The size of the sludge support 58 is the same as that of the drain plate 51. The number of sludge removal cylinders 57 and the number of drain holes 511 are the same, and each sludge removal cylinder 57 is located directly below the corresponding drain hole 511. The external dimensions of the sludge removal cylinder 57 are the same as those of the drain hole 511. The lower surface of the sludge storage box 56 is a quarter circle, and the lower surface of the sludge storage box 56 and the lower surface of the drain plate 51 can be spliced ​​to form a complete circle. Two drain holes 561 are opened on the side surface of the sludge storage box 56. A sludge storage support frame 562 is installed on the lower surface of the sludge storage box 56. A magnetic slot is opened on the inner surface of the lower drain shell 2. A magnetic block 563 is installed on the lower surface of the sludge storage support frame 562, and the outer surface of the magnetic block 563 is located inside the magnetic slot. By adding drain holes 561, the residual sewage in the sludge storage box 56 can be discharged, and the waste residue will not be blocked in the drain holes 561 due to gravity.

[0021] As a second embodiment of this utility model: When the dishwasher is in use, wastewater will pass through the drain hole 511 and the drain outlet 561, while waste residue will be intercepted by the drain plate 51 and the sludge collection box 56. When a large amount of wastewater flows, a large amount of waste residue will accumulate on the drain plate 51. At this time, the drive motor 3 is turned on, and the drive motor 3 drives the drive gear 4 to rotate. Since the drive gear 4 meshes with the external drive gear 11, the drive gear 4 will drive the upper drain shell 1 to rotate. Since the internal transmission gear 12 meshes with the scraping driven rack, when the upper drain shell 1 rotates, it will drive the scraping plate 53 to rotate around the central support 52. At this time, most of the waste residue will be scraped into the sludge collection box 56, while a small amount of waste residue will be squeezed into the drain hole 511, causing the drain hole 511 to be blocked. Then the cleaning motor 54 is turned on. The machine 54 drives the cleaning worm gear 55 to rotate through the cleaning motor shaft 541. Since the cleaning worm gear 55 and the cleaning bracket 58 are connected by threads, and the cleaning bracket 58 is in close contact with the sludge box 56, the cleaning bracket 58 cannot rotate when the cleaning worm gear 55 rotates, but can only move up and down. The cleaning bracket 58 drives the cleaning cylinder 57 to move upward until the cleaning cylinder 57 enters the drain hole 511, pushing out the waste residue in the drain hole 511. At the same time, the scraper 53 scrapes the pushed-out waste residue into the sludge box 56. By controlling the cleaning bracket 58 and the cleaning cylinder 57 to move downward away from the drain hole 511, the drain hole 511 can be prevented from becoming blocked. When it is necessary to clean the sludge box 56, the magnetic card block 563 can be removed from the magnetic card slot to remove the sludge box 56 from the lower end of the lower drain shell 2 for cleaning.
