An air cylinder (5 5), as shown in the second, τ door ° °, the first five pictures, is connected to the pinhole with the gas explosion

Page 8 M253230, Creative Instructions (5) (35) Connect the pipe (452) to make the gas explosion pinhole (35) spray water or gas explosion. A tank surface cleaning faucet (59) is installed on the top surface of the fine cleaning tank (30) as shown in the first figure, and provides clean water for cleaning fruits and vegetables or the tank surface. The use and cleaning actions of the rough washing tank (10) and fine washing tank (30) are described as follows: As shown in the second and fourth figures, tap water (non-circulating water) is added to the water injection port (丨 1). The rough washing tank (10) is closed after reaching a predetermined amount. The water level in the rough washing tank (10) should be equal to the height of the fence (21), so that the water in the tank can be filtered to the rough washing tank.

The net trough (20) flows in the direction and maintains the difference in water level between the two troughs, while the water in the coarse washing filter and the net trough (20) is pumped out by the decanter motor (25) The net bag (22) is used for preliminary filtering. The decanter motor (25) pumps out the filtered water and sprays it from the water column nozzle (1 2) through the pipe (26). Water can be reused to save water. During the cleaning process, if the water in the rough washing tank (1 0) is insufficient, the water level of the coarse washing filter tank will be lower than the water supply port (24). The water will pass through the filtering system (5) under the fine washing tank (30). 〇) The treated clean water is injected into the rough washing tank (20) through the decanting motor (45) of the fine washing tank (30) to make up the amount of water. ~ As shown in the third and fifth figures, tap water (non-circulating water) is added to the cleaning tank (30) through the water injection port (31) to a predetermined amount and then closed. The water level in the cleaning tank (30) should be equivalent to The height of the barrier (41) allows the water in the tank to flow to the fine-cleaning filter tank (40), and the filter bag (46) and the fine mesh in it are used to filter the water quality. The motor (45) draws out the water in the fine-cleaning filter tank (40) and filters it layer by layer of the filtering system (50) to decontaminate, disinfect, and sterilize

M253230 V. The clean water of the creative instructions (6) _ is sent to the vortex water inlet (32), the waterfall narrow slit hole (34) and the gas explosion pinhole (35) through the pipeline (45 1) (452) (455). It can be sprayed to achieve the purpose of repeatedly recycling the water in the fine washing tank (30). Because the vortex water inlet (3 2) is located near the corner of the side wall of the cleaning tank (30), a vortex water outlet (3 3) is set at the bottom of the other side, and the vortex water inlet (3 2) The height is higher than the vortex water outlet (33), and the vortex water outlet (33) pumps the water to the fine-cleaning filter tank (40) by the dewatering motor (25). 3 〇) the water generates vortexes (as shown in Figures 6 and 7B); furthermore, the waterfall crevices (3 4) eject flat water columns in a waterfall manner (as shown in Figures 6 and 7C) , And flush the water to the fine washing trough (40). When the gas cylinder (55) is not filled with air, the gas explosion pinhole (35) sprays water; when the gas cylinder (55) is full of gas, it is sprayed with water through the gas explosion pinhole (35) instantly. Out (such as the third and seventh a). The user can place a net basket (91) in a compartment (as shown in the first picture) to classify the items to be cleaned, and place the net basket (91) and fruits and vegetables into the rough washing tank (1 0) (also The object to be cleaned is directly placed in the rough washing tank (10)). As the water jet nozzle (12) continuously and strongly sprays water upward, the water in the rough washing tank (丨 〇) and the to-be-cleaned The objects roll, the water and the objects to be washed friction and achieve the cleaning effect, and the dirt floats on the water surface, because the water in the rough washing tank (10) will continue to flow through the 4 books (21) to the rough washing filter tank 2〇), the large dirt floating on the water surface (such as vegetable leaves or fruits and vegetables ...) will be blocked by the fence (2 丨), while the fine dirt is washed by coarse filtering, mesh trough (2 〇) The filter bag (2 2) filters, so the water pump (25) can spray relatively clean water through the water column nozzle (12). In addition to the tumble cleaning of the rough washing tank (10), the user can also cooperate with the tank surface cleaning faucet (2 9) to clean the harder dirt on the object to be cleaned. In the rough washing tank (丨 〇)

Page 10 Fifth, the object to be cleaned in the creation description (7) may contain more sediment and dirt, and the sediment and dirt will settle at the bottom of the tank. In this work, the water column nozzle (lower than the tank)丨 2) It is set higher than the bottom of the tank, the purpose is to make the height below the sprinkler head not affected by the water flow of the spraying water, so that the heavy dirt generated during the washing process will settle there. Turbidity of water in the washing tank (10). The user moves the objects to be cleaned after the rough washing tank (丨 〇) to the fine washing tank (30). The fine washing tank (30) uses the vortex action of water and the gas explosion pinhole (35). ) 'S water outlet function allows vegetables and fruits to tumble and clean with sufficient friction; and if the gas explosion pinhole (35) exhausts the gas in the gas cylinder (55), the instantaneous strength of the gas can make the objects to be cleaned. The pesticide dirt or the harder Θ scale in the medium is washed out, and the dirt or debris floating on the water surface is pushed by the waterfall-type flat water column sprayed from the waterfall narrow slit hole (34) to the fine-cleaning filter tank. (40), the larger debris is stopped by the fence (41), and the smaller debris is filtered by the filter bag (46) and the fine mesh basket (42); The water motor (4 5) pumps the water containing heavy metals and bacteria through the filtering system (50), and then filters it back into the cleaning tank after filtering, sterilizing, and sterilizing. The air burst cleaning, vortex flushing, and waterfall-type flat water column appear alternately. Therefore, the water pump motor (45), the vortex water inlet (32), the waterfall narrow slit hole (34), and the gas explosion pinhole (35) The pipeline (45 1) (452) (453) (453) (454) (455) (456) connecting the gas cylinder (55) and the gas explosion pinhole (35) is provided with a control switch (45 1 1) (452 1 ) (453 1) (4541) (455 1) (456 1) (as in the eighth figure). '' When cleaning the rough washing tank (10) and fine washing tank (30), the user will open the row M253230 V. Creation instructions (8) Water holes (13) (36) Put the inside of the tank (2 9) (5 9) In the scrubbing tank, (46) and fine mesh basket (42) In summary, the original column, vortex action, and gas explosion cleaners can be recycled and reused. They can be used as food washing machines. Reduce environmental pollution. The water can be removed and the cover can be opened to greatly reduce the cleaning effect of the foods in it, which can be greatly reduced. Although this case is a best practice, it can only be used without departing from the essence of this case. Jufan does not violate the scope of this application. God and category In order to explain the spirit of ‘clean the faucet plate (2 3) (4 3) from the tank surface, remove the dirt from the filter bag (2 2), or replace the new filter. The washing machine mainly sprays strongly the water to be washed, so it is not necessary to make fruit, but the consumption and waste of water and water in the rough and fine washing tanks are used. The use of this invention reduces labor and water costs, and reduces the number of examples. But skilled in this technique to make various forms of change. Nothing, other modifications or changes that are not used to limit the matter in this case,
