Description
Technical Field
The invention relates to the technical field of commercial cover-type dish-washing machines, in particular to a device and a method for recycling rinsing water of a commercial cover-type dish-washing machine.
Background
The normal washing process of the dishwasher includes: main washing and rinsing. The general commercial uncovered dish-washing machine (comprising the waste water heat recovery function or not) has a main washing stage which is the main working process of the dish-washing machine. During the main washing process of the tableware, under the combined action of high temperature water (50-60 ℃) and detergent (alkalinity), stains, greasy dirt and the like are removed. The rinsing process mainly removes detergent on the surface of the tableware and dries water on the surface of the tableware. Therefore, the high-temperature purified water sprayed in the rinsing process still keeps higher cleanliness after the tableware is cleaned. Main washing and rinsing of a common commercial uncovered dish washer are not designed in a space isolation area, and water sprayed from a rinsing arm in a rinsing water tank directly falls into the main washing tank. The water level of the main water washing tank is gradually raised, and the water flows into the waste water heat recovery tank through an overflow hole at the overflow pipe or is directly discharged out of the machine. In a dishwasher without waste water heat recovery, this part of the water is directly overflowed. In a dishwasher having a waste water heat recovery function, a part of heat is recovered, but the water of which the cleanliness is maintained is not fully utilized.
The rinsing process of the dish washer has two functions, one is to clean the residual main washing water on the tableware with clean rinsing water, and the other is to spray the high-temperature rinsing water mixed with drier on the tableware, thereby playing the roles of high-temperature disinfection and quick drying of the tableware.
In the prior art, a specific working mode of a dish washer with a pre-rinsing function is as follows: in the main washing stage of the dishwasher, the main washing tank, the main washing pump and the main washing arm complete the closed circulation of water in the main washing tank, the water level of the main washing tank is kept basically unchanged, and meanwhile, the main washing tank stores alkaline detergent water solution. In the rinsing stage of normal operation of the dish washing machine, the rinsing water tank, the rinsing pump, the rinsing arm and the main water tank finish the open circulation of water in the rinsing water tank, and the water level of the rinsing water tank gradually drops along with the pumping of the rinsing water pump, so that whether water is needed to be supplemented or not is judged according to the water level signal of the rinsing water tank, and meanwhile, the rinsing water tank is internally provided with a weak acid drier water solution. The rinsing of the dish washer is carried out to the main washing in each washing cycle, and the acidic drier is sprayed into the main washing, so that the concentration of the alkaline washing liquid in the main washing water tank is reduced, and the consumption of the alkaline washing liquid in the main washing water tank is indirectly increased. For this purpose, the increased pre-rinsing function of such dishwashers is mainly aimed at recovering the acidic drier liquor, spatially isolating the contact with the alkaline washing liquor in the main wash tank, and finally achieving a reduced dosage of alkaline or acidic detergent or acidic drier.
The disadvantages of the prior art are: in order to save the detergent and drier, a more complex mechanical structure and control process are required to be added; the design requirement on the mechanical parts is high. Complicated mechanisms and complicated washing link control are needed to achieve the aim of saving the detergent and drier. And the rinsing time cannot be reduced, nor the rinsing water consumption cannot be reduced.
Therefore, it is necessary to design a recycling device for rinsing water of a commercial cover-type dishwasher, to increase a pre-rinsing function, to solve the problem of using the rinsing water, to recycle the rinsing water to be stored in a pre-rinsing water tank separately and to be used for the second time, to pre-rinse the tableware after main washing, and to perform waste heat recovery for water overflowed from the pre-rinsing water tank, so as to reduce the high-temperature rinsing water, reduce the rinsing time, and reduce the water consumption and the electricity consumption, thereby achieving the purposes of energy saving and environmental protection.
