Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a rotary brush type dishwasher. Background Art

[0002] The principle of dishwashing of existing dishwashers is that a rotating spray arm sprays and rinses the dishes through the gaps between the dishes for a long time and repeatedly. Due to the improper technical principle adopted, there are many defect problems in existing dishwashers, and it is still very difficult to be widely promoted and used so far. The most prominent problems are as follows:

[0003] 1. Time-consuming. Since the existing dishwasher cleans the tableware by the water flow generated by the rotating spray arm below passing through the very small gaps between the tableware. This single intermittent small water flow passing through the gaps has a very weak scouring force on the dishes, and it cannot be rinsed clean without enough time. Therefore, it takes several hours for the existing dishwasher to wash once.

[0004] 2. Water-consuming. Since the existing dishwasher washes dishes by scouring, it cannot be rinsed well without a sufficient amount of water, so it is very water-consuming.

[0005] 3. Power-consuming. Since the existing dishwasher cleans the dishes by scouring with high-temperature and high-pressure fine water flow, it requires a lot of electricity to heat a large amount of water to a high temperature, and the long-term rotation of the spray arm also requires a lot of electricity. Therefore, the existing dishwasher is very power-consuming.

[0006] 4. Costly. When the existing dishwasher washes dishes, it needs softening salt, dishwashing tablets, and rinse aid. Roughly estimated, it costs about 3 yuan to wash the dishes once, and the cost for a year is more than a thousand yuan, not including water and electricity bills. This cost of dishwashing is unacceptable to most families. Therefore, so far, only a few families with better economic conditions use dishwashers.

[0007] 5. Incomplete cleaning. The existing dishwasher scours with intermittent small water flows, and there is only water rinsing without the action of external mechanical force. Stains that are firmly adhered are very difficult to remove. Therefore, when the washed dishes are taken out of the dishwasher, it is often found that there are still some stubborn stains. This is also the most criticized problem of existing dishwashers, spending a lot of time and money but still not being able to wash the dishes clean.

[0008] 6. Existing dishwashers place tableware upright together with only very small gaps between them, giving the impression of piling up bowls and plates. When placing bowls and plates like this, the brush cannot get in, and water also has difficulty getting in. Without sufficient time, sufficient water, sufficient power consumption, and without enough money to buy washing aids such as softening salts and dishwashing tablets, it is impossible to wash them clean. The existing dishwasher technology starts with the wrong placement of bowls and plates; coupled with using a single water flow for rinsing without the action of external mechanical force, it is compounding the mistake, so it has not been widely popularized and used so far. It can also be said that existing dishwashers are one of the most failed household appliances.

[0009] 7. Existing dishwashers generally cannot wash pots, and even if they can, they cannot wash them clean because the dirt on the pots after high temperature has stronger adhesion. Relying on the small water flow of existing dishwashers is even more powerless. Summary of the Invention

[0010] In order to solve the above problems existing in existing dishwashers, the purpose of the present invention is to provide a dishwasher that saves time, water, electricity, and money and can wash tableware clean and thoroughly.

[0011] The technical solution adopted by the present invention to solve the above technical problems of existing dishwashers: a rotary brush type dishwasher, including a housing and a cleaning system. The dish rack is a multi-hole cross-shaped structure. Each space is inverted with a bowl or a plate placed inside. The size of each space matches the size of the bowl mouth or the plate mouth. The bowl edge or the plate edge is tangent to the straight edge of the space. At each tangent point on the dish rack, there is an L-shaped fulcrum for holding and fixing the bowl or the plate;

[0012] Inside and outside each bowl and plate, there is a flushing arc tube that matches the axial section shape of the bowl and plate and has a row of flushing holes. There is a brush on the flushing arc tube. The flushing arc tube is connected and integrated with its tubular central rotating shaft to allow water to pass through. The rotating shaft is on the axis of the bowl and plate;

[0013] Above and below the dish rack, there are water supply pipes that can also serve as supports for the flushing arc tubes. The end of the rotating shaft is closed. The rotating shaft is installed with a seal and passes through the water supply pipe and is fixed on the water supply pipe. One or more water inlet holes are provided on the part of the rotating shaft inside the water supply pipe; the water in the water supply pipe enters the rotating shaft from the water inlet hole, then enters the flushing arc tube from the rotating shaft, and finally comes out from the flushing holes on the flushing arc tube to wash the bowls and plates;

[0014] After passing through the water supply pipes, a plurality of rotating shafts on the upper water supply pipe support are all installed with synchronous belt pulleys. The upper motor drives all the upper synchronous belt pulleys and the flushing arc tubes through a synchronous belt to rotate forward and backward together, and at the same time cleans the outsides of multiple bowls and plates;

[0015] A plurality of rotating shafts on the lower water supply pipe are each installed with a synchronous pulley after passing through the water supply pipe.

[0074] After adopting the above structure, compared with the prior art, the following advantages and effects are obtained:

[0075] The present invention adopts the method of placing bowl and dish in a single-opening and inverted manner in a grid format, and uses a rotating flushing pipe with a brush to independently clean each bowl and dish, 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, where the bowls and dishes are placed in an inclined and stacked manner with small gaps and cleaned by the principle of spray flushing. It has the following main advantages and remarkable beneficial effects:

[0076] 1. Time-saving. Since the flushing pipes with brushes cover both the inside and outside of the bowls and dishes, and through the dual effects of high-speed rotation for flushing the entire bowl and dish with water and mechanical scrubbing by the brushes, the tableware can be washed clean in more than twenty minutes. It has achieved a very obvious beneficial effect by reducing the time required from more than two hours of the existing dishwasher to more than twenty minutes, completely solving the problem of time-consuming of the existing dishwasher.

[0077] 2. Water-saving. Since the flushing is carried out through the flushing pipes, and the structure directly flushes the inner and outer surfaces of the bowls and dishes evenly. Coupled with the simultaneous friction scrubbing of the tableware surface by the brushes, only a small amount of water is needed to clean the entire bowl and dish, achieving the ideal effect of water-saving.

[0078] 3. Power-saving. Since the structure of rotating brush type for dishwashing with flushing pipes is adopted, it is not necessary to heat the water to a very high temperature. Coupled with the small amount of water required and the short rotation washing time of the brushes, the electricity consumption is very small, achieving the ideal effect of power-saving.

[0079] 4. Cost-saving. Since the structure of rotating flushing pipes with brushes for dishwashing is adopted, it is no longer necessary to use softening salt and dishwashing blocks when washing dishes, and only a few cents of detergent is needed. Coupled with water-saving and power-saving, the ideal effect of cost-saving is achieved.

[0080] 5. The tableware is washed clean and thoroughly. Since the structure of rotating flushing pipes with brushes for dishwashing is adopted and a high-pressure water pump is added, the scouring force of water is further enhanced. When washing the dishwashing tray, while the high-pressure water of the flushing pipe performs ultra-close flushing on the surface of the bowl and dish, coupled with the mechanical sweeping force of the brush acting on the surface of the bowl and dish, even stubborn stains can be washed away with both methods, washing the bowl and dish clean, achieving an efficient, clean and thorough cleaning effect.

[0081] 6. Since the upper cleaning component and the lower cleaning component are hinged, and the upper cleaning component can be lifted when taking and placing tableware, it is very convenient to take and place the bowls and dishes.

[0082] 7. Since the mechanism of a rotary brush type cleaner for chopsticks, spoons, knives and forks is arranged in the dishwasher, due to the simultaneous mechanical scrubbing force of the rotary brush and the rinsing of water, the cleaning of chopsticks, spoons, knives and forks is not only efficient and cost-saving, but also has a better cleaning effect.

[0083] 8. Since the structure is such that all sewage enters the food residue processor for grinding and then is discharged into the sewer, even if the leftover food in the tableware is not emptied completely, the sewage discharge pipe of the dishwasher will not be blocked.

[0084] 9. Since the cleaning method of rotating the flushing arc pipe with a brush is adopted, round and square bowls, plates and dishes can be cleaned; since the structure of rotating the rolling brush for flushing the long plate by the rotating shaft is adopted, all rectangular tableware can be cleaned. Therefore, the present invention creatively solves the problem of efficiently cleaning all bowls, plates and dishes with a flushing brush, opening up a new world for the cleaning technology of bowls, plates and dishes.

[0085] 10. Since the structure of both a brush and a wire brush is adopted on the rotating flushing arc for washing the pot, even if there is stubborn dirt attached due to high temperature, the inside and outside of the pot can be cleaned thoroughly. BRIEF DESCRIPTION OF THE DRAWINGS
