Description
Technical field
The present invention relates to cleaning machinery technical field more particularly to a kind of cleaning and dirt separation systems.
Background technique
Since ultrasonic washing machine has many advantages compared to traditional rotary drum washing machine and roller washing machine, closely
Explosive growth is presented for the research of ultrasonic washing machine both at home and abroad within 3 years.Traditional rotary drum washing machine and roller washing machine it is clear
Washing principle is mainly to rely on smearing tea and beat to clothes between clothing, while must additionally be subject to a large amount of detergent, tradition
Laundry principle do not adapted to people-oriented and harmonious co-existence between man and nature modern concepts, this is because conventional washer
It is big to clothing damage, while detergent is also bigger to the pollution of ambient water quality.
Ultrasonic washing machine is a kind of washing machine vibrated using ultrasonic wave high-frequency, and through ultrasonic wave under liquid environment
The physical phenomenon of cavitation is generated to liquid.Currently, influencing principal element and the cavitation generation hole of ultrasonic washing machine cleaning effect
Force of explosion it is related with the space density in hole, on clothing the removal of spot rely primarily on hole generated after liquid implosion it is micro-
Flowing and the shearing to spot first destroy the viscous boundary layer of spot to disengage it from clothes fiber, then by instantaneous micro-
Spot is washed from clothes fiber by flowing, can be obtained from above-mentioned principle, and the principle of supersonic cleaning is different from traditional technology principle, compared with
Traditional non-ultrasonic washing machine, ultrasonic washing machine can reduce or without using detergent, while can be by washing efficiency significantly
It improves.
Existing ultrasound laundry mode is mainly to be divided with space structure type, and mode of mainly doing washing can be drawn
It is divided into following several: A, assists decontamination type: utilizing the ultrasonic wave for the outer barrel inner wall or interior bucket outer wall for being set to conventional washer
To carry out the bucket cleaning of washing machine；B, it assists cleaning type: using the outer barrel inner wall for being set to conventional washer or being set to other
The ultrasonic wave of non-inner barrel wall is cleaned by ultrasonic the clothing in washing tub or assists cleaning；Or ultrasound unit is placed in tradition
The separate space of washing machine carries out independent cleaning for small-sized clothing；C, ultrasound laundry ball-type: portable ultrasonic wave bead is utilized
Be set in the interior bucket or generic container of conventional washer and clothing cleaned: D, combined type: using peripheral hardware gas and
The technologies such as electric heating are sterilized and are dried, using portable power combined ultrasonic generator to clothes cleaning etc..With above-mentioned A, B
The ultrasonic washing machine of two kinds of cleaning ways is larger to the dependence of traditional rotary drum washing machine and roller washing machine, relatively conservative
Layout strategy is the transition for the laundry technology dominated from traditional technology to ultrasound；Laundry with above-mentioned two kinds of cleaning ways of C, D
Machine shows higher competitiveness, be on the one hand due to small in size, thus have the advantages that it is easy to carry, on the other hand be cleaning
Power is high, has the characteristics that close friend to environment.
But existing super refreshing washing machine described above has the disadvantage in that (1) in the prior art, ultrasonic transducer
It is even farther to be placed in washing tub outer wall, so that ultrasonic wave, because of deep fades, most of energy of ultrasonic wave completely cuts off in washing machine
Except inner cylinder, so that can be really very limited with the effect for generating cleaning on clothing；(2) energy of air pocket produced by ultrasonic wave
Power is insufficient, so that the efficiency of ultrasonic cleaning reduces；(3) in ultrasonic cleaning process, the liquidity of water flow can be to cleaning
Effect has a major impact, and traditional technology is overly dependent upon additional stirring source, is unfavorable for structure and simplifies, and utilizes in ultrasonic wave air pocket
Though the miniflow of quick-fried generation can be detached from clothing to spot and play positive effect, coverage is than relatively limited.

Property excitation it is lower caused by repetitive distortion, for removing submicroscopic spot.
The working frequency of piezoelectric ceramic piece is set as between 20KHz-250KHz, shows to be cleaned by ultrasonic effect simultaneously after study
Will not with supersonic frequency increase and increase, influence be cleaned by ultrasonic effect cause be known as very much, as ultrasonic frequency, clothing away from
Supersonic source distance, environmental factor (temperature, air pressure), spot type, cleaning duration etc..But utilize ultrasonic cleaning clothes institute benefit
The most fundamental mechanism is that ultrasonic wave generates implosion physical phenomenon caused by the implosion in hole in a liquid.All influences are empty
The factor of cave implosion finally can all have an impact the effect of ultrasound laundry.
Normal temperature and pressure frequency and the relationship of hole radius substantially can be described as: f*R=300, supersonic frequency is higher, air pocket
Radius is with regard to smaller, it is seen that frequency increase keeps the viscous boundary layer of spot thinning therefore the radius in hole and supersonic frequency are closed in inverse ratio
System.
Ultrasonic wave under tens of thousands of hertz is conducive to effectively remove microcosmic spot (dust, bloodstain, mechanical abrasive grain),
Reason is that tens of thousands of hertz of ultrasonic wave allows hole just to generate implosion when growing to larger, although spot viscous boundary layer at this time
Thicker, the shearing force that air pocket implosion generates still has original function and effect to relatively large microcosmic spot.And with ultrasonic wave
When increasing to 200Khz or more of frequency, hole can generally reduce, but since the frequency of implosion is accelerated, generate liquid miniflow very
High instantaneous flow, and spot viscous boundary layer is thinning under high frequency, so that high frequency ultrasound wave energy is penetrated viscous boundary layer and removes clothing
Submicroscopic spot (spot of drop, fingerprint, other molecular scales) on fiber makes submicroscopic dirt in conjunction with the microfluidic of high speed
Stain is far from clothes fiber.
