In the technical program, the operation principle of self-resonating cavitating jet scale removal is as follows:
At first, laundry water in the dehydration barrel 4 rotates under the effect that impeller rotates, consequent centrifugal action is on dehydration barrel 4 inwalls, so that nozzle locates than liquid outlet higher pressure reduction is arranged near the liquid inlet of dehydration barrel 4 inwalls one side, obvious aperture greater than liquid outlet is wanted in the aperture, liquid inlet of nozzle simultaneously, make the laundry water that flows through nozzle form cavitation jet at liquid outlet, cavity in the jet is grown up under pressure variation effect, when containing the jet impulse cover bucket wall of these cavitys, cavity near reaching, cover bucket wall surface is broken, because the energy height that produces during cavity collapse is concentrated, and be confined on many very little areas, thereby concentrate at high surge and the stress of the many regional areas generations of cover bucket wall surface, the dirt of cover bucket wall surface is destroyed rapidly, thereby reach powerful purpose of cleaning, this local pressure amplification of cavitation jet makes its cleaning performance greatly be better than non-cavitation jet (cascade that uses among the Chinese patent ZL201010100155.4 cleans and just belongs to non-cavitation jet).
Secondly, the generation of cavitation jet need to produce enough pressure reduction at the two ends of nozzle, and pressure reduction is larger, and effluxvelocity is faster, and cavitation effect and cleaning performance are better.The pressure reduction less that the centrifugal pressure of dehydration barrel 4 interior laundry waters forms, in order to improve the cleaning performance of the cavitation jet under the low voltage difference, nozzle has adopted self-resonating cavitating jet nozzle 220.Theoretical and the marine acoustics principle according to transient state stream, when stabilized fluid flow through the outlet necked-down section of nozzle resonator, it was exciting to produce self-excitation pressure, and this pressure excitement feeds back to the feedback pressure vibration that resonator forms.By the control resonant cavity size of optimal design and Mach number and the Strouhal number (implementation of this control can be undertaken by the default computer program in the washer control panel) of fluid, the frequency of feedback pressure vibration and the intrinsic frequency of resonator are complementary, thereby the humorous resonance of formation sound in resonator, make the jet expansion jet become interrupted collar vortex, thereby strengthen the cavitation of jet.
At last, the inwall of steel ladle 5 is transformed into the surface configuration with a plurality of jet reflection cambered surfaces.The cavitation jet that sprays from the self-resonating cavitating jet nozzle 220 of dehydration barrel 4 acts on the inwall cambered surface 50 of steel ladle 5, part cavity in the jet is grown up to critical point under pressure variation effect, when jet impulse, cavity breaks near the inwall cambered surface center of steel ladle 5, concentrate at surge and stress that this zone generation is high, the dirt on surface is destroyed rapidly.Part is not yet grown up and is moved to the outer wall of dehydration barrel 4 together to the cavity of critical point and the jet of cambered surface reflection in addition, near the outer wall of dehydration barrel 4, grow up to critical point, break and the dirt of the outer wall of impact, cleaning and dewatering bucket 4, thereby reach the cleaning performance that cleans cover bucket inwall.The size of cambered surface, radian, position can be optimized when design and make cleaning performance reach best.In addition, because dirt is easier of the groove alluvial, the cambered surface of design is the most serious place of dirt often, more is conducive to bring into play the cleaning capacity of cavitation jet.
Descaling function of the present utility model can regularly carry out by default computer program.During scale removal, make the dewatering hole of dehydration barrel 4 be in closure state, open entering water electromagnetic valve 11 and add water to full-water level.Make the impeller high speed rotating, open dewatering hole, open drain solenoid valve 20, self-resonating cavitating jet nozzle 220 produces cavitation jet and begins cleaning sleeve bucket inwall under the centrifugal pressure effect.Simultaneously, washing machine also can produce cavitation jet and automatically carries out scale removal when daily dehydration.

In the technical program, the operation principle of pore area is as follows:
At first, adopt above-mentioned pore area, can guarantee washing machine when laundry, the dewatering hole on the dehydration barrel 4 can seal because of the covering at the interval between pore area 23 water saving holes, does not have laundry water to enter between the cover bucket when making laundry, to reach the effect of economizing on water and preventing the dirt alluvial.And for pore area 23 and dehydration barrel 4, pore area 23 only can be at the direction of the every row dewatering hole of dehydration tube relative sliding up and down, and when laundry, the cylinder of rotation also acts on an outside centrifugal force to pore area, these have all further guaranteed the interval between pore area 23 water saving holes, to the sealing covering of the dewatering hole on the logical inwall that dewaters.
Secondly, when dehydration, the slip on pore area 23 relative dehydration barrel 4 every row dewatering hole directions overlaps water saving holes and the dewatering hole center of circle, to guarantee normal dehydration.This design makes washing machine have the water saving usefulness of barrel washing machine in the atresia and the high-efficiency dehydration function of porose interior barrel washing machine concurrently.
