Description

Rotating brush dishwasher Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a rotary brush type dishwasher. Background Art

[0002] Existing dishwashers use a rotating spray arm to repeatedly rinse dishes through the gaps between them over a long period of time. This technology suffers from low efficiency and several technical flaws, making it difficult to widely adopt and promote. Currently, the penetration rate of dishwashers in Japan and South Korea is only around 30%, and in my country, it's less than 5%. The main problems with existing dishwashers are as follows:

[0003] 1. It's time-consuming and water-consuming. Existing dishwashers use rotating spray arms to generate water, which washes through the tiny gaps between dishes. This intermittent, small stream of water through these gaps has a weak cleaning effect on dishes. Without sufficient time and water, a full rinse is inadequate. Consequently, a single wash cycle with existing dishwashers can take several hours and consume a significant amount of water.

[0004] 2. They are relatively energy-consuming. Existing dishwashers rely on a high-temperature, high-pressure, fine stream of water to clean dishes. Heating large amounts of water to high temperatures requires a lot of electricity, as does the long-term rotation of the spray arms. Therefore, existing dishwashers are relatively energy-consuming.

[0005] 3. The high cost of dishwashing. Existing dishwashers require softening salt, dishwashing tablets, and rinse aid. A rough estimate suggests a single wash costs around 3 yuan, or over 1,000 yuan per year, not including utility bills. This cost is prohibitive for most families, and thus, only a few well-off families use dishwashers. This high cost is a major factor in the low penetration rate of existing dishwashers.

[0006] 4. Sometimes it doesn't clean thoroughly. Existing dishwashers rely on intermittent small streams of water to flush. With only water flushing and no external mechanical force, it is difficult to remove stains that are stuck firmly. Therefore, it is often found that some stubborn stains still cannot be washed off. Summary of the Invention

[0007] In order to solve the above problems existing in the existing dishwashers, the purpose of the utility model is to provide a dishwasher that saves time, water, electricity and money and washes dishes cleanly and thoroughly.

[0071] After adopting the above structure, compared with the prior art, the following advantages and effects are achieved:

[0072] The present utility model adopts the placement method of a single-opening and inverted buckling of dishware in a grid pattern, and uses a rotating flushing pipe with a brush to independently clean each dishware, which is a subversive change to the existing dishwasher in terms of the cleaning principle. It completely solves the defects and deficiencies of the existing dishwasher, which stacks dishware obliquely with small gaps and uses the principle of spray flushing for cleaning. The main advantages and remarkable beneficial effects are as follows:

[0073] 1. Time-saving. Due to the full coverage of the flushing pipes with brushes both inside and outside the dishware, the high-speed rotation flushes the entire dishware and the mechanical force of the brushes is used for scrubbing. The dishes can be washed clean in more than twenty minutes. It has achieved a very obvious beneficial effect by reducing the time from more than two hours required by the existing dishwasher to more than twenty minutes. It completely solves the problem of time-consuming of the existing dishwasher.

[0074] 2. Water-saving. Since the flushing is through the flushing pipes, which directly and evenly flushes the inner and outer surfaces of the dishware, and the brushes scrub the surface of the dishware at the same time, only a small amount of water is needed to clean the entire dishware, achieving the ideal effect of water-saving.

[0075] 3. Energy saving. Due to the adoption of a rotating brush-type dishwashing structure with a flushing pipe, there is no need to heat the water to a very high temperature. In addition, very little water is required and the brush rotates and washes for a very short time, so very little electricity is used, achieving the ideal effect of saving electricity.

[0076] 4. Save money. Due to the adoption of a rotating dishwashing structure with a flushing pipe with a brush, you no longer need to use softening salt or dishwashing tablets when washing dishes. Only a few cents of detergent is needed. In addition, it saves water and electricity, thus achieving the ideal effect of saving money.

[0077] 5. Wash dishes thoroughly and cleanly. The rotating brush-equipped flushing pipe and high-pressure water pump further enhance the flushing force of the water. While the high-pressure water from the flushing pipe provides a close-up rinse to the dishes, the mechanical sweeping force of the brush acts on the surface. This two-pronged approach removes even the most stubborn stains, ensuring an efficient, clean, and thorough cleaning effect.

[0078] 6. Since the upper cleaning component is hinged to the lower cleaning component, the upper cleaning component can be lifted up when taking and placing tableware, making it very convenient to take and place dishes.

[0079] 7. Since a roller brush type chopstick, spoon, knife and fork cleaning device is installed in the dishwasher, the mechanical scrubbing force of the roller brush and the rinsing of water are carried out simultaneously, making the cleaning of chopsticks, spoon, knife and fork not only efficient and cost-effective, but also having a better cleaning effect.

[0080] 8. Since all sewage enters the food waste processor for grinding and then discharged into the sewer, even if the leftovers in the tableware are not dumped cleanly, it will not clog the sewage pipe of the dishwasher.

[0081] 9. The rotating brush-equipped flushing arc can clean both round and square dishes. The rotating roller brush, flushed by a rotating shaft, can also clean rectangular dishes. This new device solves the problem of efficiently cleaning all dishes with a flushing brush, creating a new era in dishwashing technology.

[0082] 10. As the rotating flush arc of the pot washing machine is equipped with both a brush and a wire brush, the pot inside and outside can be cleaned even if the dirt is firmly attached due to high temperature. BRIEF DESCRIPTION OF THE DRAWINGS
