Description

Technical Field

[0001] This utility model relates to the field of dishwasher technology, specifically to a multi-stage wastewater filtration and circulation structure for an intelligent dishwasher. Background Technology

[0002] A household smart dishwasher is a kitchen appliance that replaces manual washing of dishes, plates, cups, spoons, chopsticks, knives, forks, pots, pans, and other tableware and cooking utensils. The dishwasher works primarily based on mechanical rinsing, the chemical action of detergent, and soaking in hot water. A motor-driven pump pressurizes water into a high-pressure jet, while a heating element rapidly heats the water. The hot water, mixed with detergent, is sprayed from the spray arms, which rotate due to the reaction force of the water, providing a 360-degree thorough cleaning of the tableware. During this process, the detergent breaks down grease and food residue on the surface, while the hot water soaks and expands food residue, causing it to quickly decompose and detach, thus achieving a cleaning effect. Furthermore, after washing, residual heat or high-temperature heating is used to dry the tableware, and some dishwashers also have a sterilization function.

[0003] However, existing dishwashers require a lot of water during use, and the wastewater generated by the dishwasher when cleaning dishes contains a lot of debris. Direct discharge of this wastewater would result in a significant waste of water resources and a substantial increase in the operating cost of the dishwasher. In addition, the debris would clog the water pipes, causing adverse effects. Therefore, this does not meet the current needs. To address this, we have proposed a multi-stage filtration and circulation structure for intelligent dishwasher wastewater. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-4 One embodiment of this utility model provides: a multi-stage wastewater filtration and circulation structure for an intelligent dishwasher, including a bottom support 1: A fixed bracket 3 is installed on the upper end of the bottom bracket 1. A connecting shaft 4 is installed on the upper end of the fixed bracket 3. A rotating connector 5 is installed on the outside of the connecting shaft 4. The rotating connector 5 is rotatably connected to the connecting shaft 4. A rubber replacement filter cartridge 6 is installed on the outside of the rotating connector 5. Installing the rubber replacement filter cartridge 6 allows for quick replacement of the clogged graded filter basket 7 in conjunction with the rotating connector 5. This eliminates the need for extensive disassembly of the device when replacing the graded filter basket 7, reducing the difficulty of replacing the graded filter basket 7 and making the device more convenient to use. The graded filter basket 7 is installed inside the rubber replacement filter cartridge 6. Installing the graded filter basket 7 allows for multi-stage filtration of wastewater, enabling wastewater reuse, improving water utilization, and thus reducing the operating cost of the dishwasher. It also prevents debris from clogging the water pipes during dishwasher drainage, causing adverse effects. The graded filter basket 7 is connected to the rubber replacement filter cartridge 6 through a slot. There are sixteen graded filter baskets 7, which are arranged from top to bottom as coarse filter screens and fine filter screens. The flow guide bracket 2 is installed at both ends of the rubber replacement filter cartridge 6. A sliding bracket 11 is installed on the outside of the flow guide bracket 2. Installing the sliding bracket 11 can drive the filter screen removal push rod 14 to move upward, so that the filter screen removal push rod 14 pushes the blocked grading filter basket 7 out of the rubber replacement filter cartridge 6, thereby facilitating the quick replacement of the grading filter basket 7 by the staff and enhancing the convenience of the device. At the same time, the sliding bracket 11 can limit the flow guide bracket 2 to prevent the flow guide bracket 2 from falling. The sliding bracket 11 and the flow guide bracket 2 are longitudinally slidably connected by a slot. A connecting rod 10 is installed on the outside of the sliding bracket 11 and is welded to the sliding bracket 11. A filter screen removal push rod 14 is installed at the upper end of the sliding bracket 11 and is welded to the sliding bracket 11.

[0016] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom support 1 is fixedly connected to the flow guide support 2. The bottom connecting pipe 13 is installed at the lower end of the bottom support 1 and is connected to the bottom support 1 by threads. The top support 8 is installed at the upper end of the flow guide support 2 and is fixedly connected to the flow guide support 2. The top connecting pipe 12 is installed at the upper end of the top support 8 and is fixedly connected to the top support 8. The upper end of the connecting shaft 4 is equipped with a storage handle 9. Installing the storage handle 9 allows workers to temporarily place some tools on it, which is convenient for workers to inspect and maintain this device. The storage handle 9 is welded to the connecting shaft 4. The connecting shaft 4 is fixedly connected to the fixed support 3. The bottom support 1 is welded to the fixed support 3. The rubber replacement filter cartridge 6 is welded to the rotating connector 5.

[0017] Working Principle: During use, wastewater enters the guide bracket 2 through the top connecting pipe 12, then flows through the rubber replacement filter cartridge 6 and is filtered by the grading filter basket 7. Finally, the filtered water is discharged through the bottom bracket 1 and the bottom connecting pipe 13 and reused by the dishwasher. When a large amount of impurities are filtered out inside the grading filter basket 7, the operator rotates the rotating connector 5, causing the rubber replacement filter cartridge 6 to rotate. This removes the clogged rubber replacement filter cartridge 6 from the internal grading filter basket 7, allowing a new internal grading filter basket 7 and rubber replacement filter cartridge 6 to move outside the guide bracket 2. Because the rubber replacement filter cartridge 6 has a certain degree of elasticity, its upper and lower ends can make tight contact with the guide bracket 2, preventing leakage. Then, the operator pulls the connecting rod 10 upwards, causing the sliding bracket 11 to move the filter screen removal push rod 14 upwards, thereby allowing the filter screen removal push rod 14 to remove the clogged filter cartridge. The stage filter basket 7 ejection device allows operators to quickly replace the stage filter basket 7. The device is equipped with a rubber replacement filter cylinder 6, which, in conjunction with the rotating connector 5, allows for rapid replacement of clogged stage filter baskets 7. This eliminates the need for extensive disassembly of the device when replacing the stage filter basket 7, reducing the difficulty of replacement and making the device more convenient to use. Installing the stage filter basket 7 enables multi-stage filtration of wastewater, allowing for wastewater reuse and improving water utilization, thereby reducing the operating cost of the dishwasher. It also prevents debris from clogging the water pipes during dishwasher drainage, avoiding adverse effects. The sliding bracket 11 moves the filter screen removal push rod 14 upwards, allowing it to push out clogged stage filter baskets 7 from the rubber replacement filter cylinder 6, facilitating quick replacement and enhancing the device's convenience. Simultaneously, the sliding bracket 11 limits the flow guide bracket 2, preventing it from falling off.
