Cleaning effect is enhanced to effect, when water level is higher, other adjacent spray apertures of spray arm, spray orifice 1, spray orifice 2 20, spray orifice
3 30 and spray orifice 5 50, spray orifice 6 60, spray orifice 7 70 opening direction towards same direction of rotation spray be mixed with bubble
Water energy be formed with turbulent flow, mix that bladdery turbulent flow can be washed into fruits and vegetables to be cleaned and then the quick-fried power of sky formed also increases severely, by
Impact force and frictional force in this unit volume generated greatly increase, even if not using any surfactant or detergent
In the case where, reach good washing effect, to realize more comprehensive cleaning.In addition, the O-shaped annular channel of the present invention is along water
Direction is flowed, from upstream to downstream, the sectional area of annular channel is gradually reduced.Since the sectional area of annular channel is from upstream to downstream
It gradually reduces, so that the downstream that the flow velocity of water flow is small in sectional area, the flow velocity of water flow is with regard to big, and the upstream big in sectional area, water
The flow velocity of stream is with regard to small, for this purpose, the water pressure that the spray apertures in spray arm body downstream spray can just be washed into greatly fruit to be cleaned
Each surface of vegetable, reaches the cleaning at no dead angle, obtains preferable cleaning effect, in this way it is possible to prevente effectively from fruits and vegetables to be cleaned
Deposition and avoid close to water trough body two sides dead angle position be easy because the dynamics of current scour not enough due to occurs cleaning extremely
The problem of angle.
Fruit-vegetable cleaner of the invention is due to using above-mentioned spray arm configuration, when cleaning, fruits and vegetables to be cleaned are put into
In the cleaning basket of water trough body, by being located at the bubble generator and bubble mouth of flow path upstream, water flow is sent out by bubble
Generating apparatus generates a large amount of bubbles, and the water flow with bubble is sprayed from spray arm spray apertures, the water flow of ejection because being rich in bubble,
When reaching the fruit and vegetable surfaces for needing to clean, bubbles burst forms impact force again, is peeled off together the dirty of fruit and vegetable surfaces with water flow
Dirt, with spray arm spray apertures it is simultaneous be spray arm top bubble mouth, secondary bubble is carried out to the water flow of ejection, no
Stop production raw bubble implosion effect, and finger on irregular fruit and vegetable surfaces is allowed to be difficult to touch, such as the particle foul shake in fine crack
It is in addition from lower 13 water inlet of spray arm that tap aspirator is O-shaped to two sides because the dead angle of less cleaning may be not present from fruit and vegetable surfaces
Annular channel includes two sub- runners i.e. the first subflow road 21 and to guarantee stable water pressure, each O-shaped annular channel again
Two subflow roads 22, it is consistent to control every Shu Shuiliu spray pressure, at flow field end, is separated by retaining wall, prevents water flow from crossing pair
Punching, influences discharge pressure.Same direction rotates left and right spray arm in water, is each formed with turbulent flow respectively, turbulence excess, from
And realize more comprehensive cleaning, avoid local location from rinsing sordid phenomenon, but also water can be saved.
Embodiment 2
Substantially similar to the structure of embodiment 1, difference is: as shown in fig. 7, runner is radial pattern runner, that is, being divided into
Three sub- runners, respectively third subflow road 103, the 4th subflow road 104 and the 5th subflow road 105, each subflow road are corresponding
At least three spray apertures are provided on wall surface, it is consistent to control every road Shu Ziliu spray pressure.
