Background technology

Ozone is the very outstanding chemicals of a specific character, can not only kill various bacterial viruses moment, can also the harmful chemical pollutant of resolution process.Because the ozone short time is reduced to oxygen, there is not any residue, do not cause secondary pollution, thereby ozone is called as safest " green " disinfectant, be specially adapted to the sterilization of entrance food and utensil, in Treatment of Industrial Water equipment, be widely used.

This class of dish-washing machine relates to the small-sized washing sterilizing equipment decontaminating apparatus of entrance food and utensil, be starved of and utilize ozone, but enjoy the excellent characteristic less than ozone always, wherein one of main reason is: do not have a kind of, be fit to the small-sized washing facility of this class of dish-washing machine, ozone can be mixed technology soluble in water and device fully, efficiently.The aeration method of similar fish jar oxygenation, though simple in structure, the ozone dissolved efficiency is extremely low, and is just unreasonable from principle.Select the jet hybrid technology for use, though the ozone dissolved efficiency improve than the former, can reach 50%, but also not high enough, also to set up the higher water pump of hydraulic pressure, the system structure complexity, inapplicable.The ozone dissolved efficiency is extremely important, because ozone is discharged in the air, airborne ozone concentration height has stimulation to people's respiratory apparatus, and too high ozone concentration has injury to human body, and there is corresponding ozone concentration environmental standard in country.

Summary of the invention

The present invention is directed to the small-sized elution device of this class of dish-washing machine, propose a kind of product of brand new, introduce ozone technology, utilize the excellent characteristic of ozone, be particularly suitable for the cleaning and sterilizing of food and utensil.In order to make ozone fully be dissolved in water, adopt the impeller-driven water of high-speed rotation, produce strong turbulent flow whirlpool, rely on strong turbulent flow whirlpool that the bubble in the water is pullled and be shredded into more more tiny bubbles, obtain higher gas-water contact area, thereby realize high ozone dissolved efficiency.Adopt the structure that container case and base can convenient dismounting, make the user easy to operate, and safe and reliable.

Technical scheme of the present invention is: critical piece includes: container case, base, impeller, pump case, spray bull stick, article rack, motor, ozonator also have the power supply electric component.Processed article are placed on the article rack, the motor-driven wheel rotation, and the motion of vane drive water on the impeller produces strong turbulent flow whirlpool, pulls and is shredded into more more tiny bubbles sneaking into bubble ozoniferous in the water, obtains high gas-water contact area; Row has several spray orifices on the spray bull stick, and the spray bull stick rotates by the thrust that injection water produces, and the Ozone Water that contains that ejects is directly drenched on the processed article on the article rack, and the spot on the article is rinsed out.Feature of the present invention is: be provided with the spray bull stick on case lid or in the container case; Motor is in base, and impeller is in container case, and impeller is furnished with pump case, constitutes water pump structure; Container case is placed on the base, on container case can take off and place from base easily; Driving between impeller and the motor connects has adopted shaft coupling to have axle to drive connection, or the non-contact magnetic force driving connects.

So-called whirlpool, the speed that is exactly each point in the velocity field of the fluid that moves is inconsistent, speed (vector) gradient is arranged, turbulent flow whirlpool intensity height, it is exactly the velocity gradient height, having in the presence of the bubble, the speed of bubble surface each point is consistent in the speed of this point with fluid (water), but each point fluid (water) speed is inconsistent, consequently spherical bubbles is pullled elongated, attenuation, under the effect of turbulent flow pulsation, a bubble is shredded into two or more bubbles, is that is to say the surface tension that overcomes water like this, the strength that underwater bubble is torn up is whirlpool (velocity gradient), velocity gradient is more big, and namely whirlpool is more strong, and the power of tearing is also just more big, then can tear into littler bubble, underwater bubble is more little, quantity is more many, and the area of G﹠W contact is just more big, and the efficient that ozone gas is dissolved in the water is more high.

Impeller and pump case constitute water pump structure, when the impeller-driven water of rotation moves, and energy turbulization whirlpool, wheel speed is more high, and the flow of pump is more low, and turbulent flow whirlpool intensity is more strong.Impeller pump has three kinds of versions, and the one, axial-flow type, the 2nd, centrifugal, the 3rd, eddy current type.The whirlpool intensity that axial-flow type produces is minimum, from topology layout, also is not suitable among the present invention.Centrifugal and eddy current type topology layout is applicable to the present invention, and both compare, and in turbulence type pump, turbulent flow whirlpool intensity is the strongest.What the gas-liquid mixing pump in the commercial Application adopted is exactly the turbulence type pump structure, and the underwater bubble diameter is little of 20～30 μ m, and the ozone dissolved efficiency can reach 98%.

The method that the present invention adopts can reduce the flow of pump by improving wheel speed, adopts the turbulence type pump structure, then can obtain enough strong turbulent flow whirlpool, makes the bubble that is mixed in water enough little, obtains ozone dissolved efficiency sufficiently high, that can meet the demands.By the pump that impeller and pump case constitute, be not only air-water mixing pump, but also be to produce the circulating pump that jet drip washing is used for the spray bull stick.The spray bull stick rotates, and makes article on the article rack by evenly drip washing, dashes pouring harmful chemical agent that also can sterilize, degrade with water ozoniferous.

In the present invention, impeller is arranged in the container case, water just flows at the container case internal recycle, has saved the sealing and anti-leakage problem of pump case, water pipe head etc., and the reliability height is avoided the electrical safety problem that causes owing to leaking.On container case can take off and place from base easily, the base that electrical equipment is housed in making and has an external power supply patch can maintain static, the user only need move container case, water intaking, pouring and clean container case, not only easy to operate, in the time of can preventing from moving base again, particularly during the clean container case, water flows in the base, causes unsafe problems such as inner electrical leakage, short circuit.

Motor is in base, and impeller will realize that container case and base can convenient dismounting in container case, must solve the driving connectivity problem between motor and the impeller.Adopted the axle driving being arranged and do not have the axle driving by the noncontact of magnetic force by shaft coupling among the present invention.But shaft coupling separated into two parts, a part are fixed on the axle of impeller, and another part is fixed on the axle of motor, and by shaft coupling, the moment of torsion of motor is delivered on the impeller, but and relativity shift and the dislocation of small electromotor and impeller diaxon.Non-contact magnetic force drives more superior, and the sealing and anti-leakage problem of axle when not having the axle driving allows motor and impeller diaxon that bigger relativity shift and dislocation are arranged, structure is simpler, reliability is higher, can realize that all tumblers are hidden in the casing, is convenient to impeller and changes and clean.
