Detailed description of the invention
As shown in Figure 1, the present invention adopts the gears to engage and disengage on the interior bucket of following steps guarantee and driving shaft convenient.
101, washing procedure starts rear detection equivalent water level;
Because interior bucket is elevated by buoyancy of water, therefore water level is only had to acquire a certain degree, interior bucket just can float (namely buoyancy is greater than the weight of interior bucket), but interior bucket cogs with driving shaft when not floating and is bonded together, now by clothing, the gravity effect of the water yield and interior bucket self, gear on interior bucket and the gear engagement place on driving shaft can form a kind of bonding force, the rising of bucket in hindering, even if when now buoyancy of water reaches the water level making interior bucket rise, interior bucket can not float, at this moment just the gear to engaging is needed to apply an external force to destroy this bonding force.
102, drive motors carries out of short duration rotating forward and reversely rotate action;
When water level does not reach washing location, drive motors carries out slowly rotating forward and reversely rotating in short-term, the time controling wherein rotated forward and reversely rotate is within 1 second, the angle rotating forward or reversely rotate is no more than 90 °, and speed can not be too fast, namely drive motors forward and oppositely between do and severally to rotate back and forth slowly, the object reaching loosening gear engagement just can.Because motor driving time is oversize or too soon, when two gears are not thrown off, can produce certain destruction to gear, or there is the problem being with water rotation.So not only water can overflow, and the load of motor also can increase the weight of, and affects service life of gear.Therefore can produce one between gear on gear on the driving shaft be fastened togather and interior bucket and get rid of de-power, overcome the gravity between two gears and bonding force, make interior bucket leave the gear on driving shaft with the increase of water easily and rise along driving shaft.
103, interior bucket starts washing after floating up to precalculated position;
This process comprises washing process and rinse cycle at least one times.
104, when washing procedure discharges water to precalculated position after terminating, start drive motors and carry out of short duration rotating forward and reversely rotate action;
The water yield now in washing machine is reducing gradually, interior bucket declines along driving shaft always, the gear of bottom of the barrel can be positioned at the Gear Contact of outer barrel bottom with driving shaft, ideally, two gears just in time engage, but owing to being engaged by tongue and groove correspondence between two gears, therefore this situation about just in time engaging seldom occurs.This programme, in the process of water level decreasing, adopts the mode drive motors same with 102 steps to rotate forward and reversely rotate, and interior bucket is initiatively engaged with the gear on driving shaft in decline process.
105, water discharges rear beginning dehydration procedure and terminates to washing procedure.
Now the gear of bottom of the barrel is owing to engaging with the gear on driving shaft, and therefore the rotation of driving shaft will drive interior bucket to rotate, and completes the dehydration of the rear clothing of washing.Open ozone generator and carry out disinfection to clothing while dehydration, ozone is squeezed in water by air pump and aeration stone, is dissolved into water, can better also can reduce to be discharged in air and causes certain smell by sterilizing.
As shown in Figure 3, the rotating speed of motor when dewatering beginning is a progressive process, as shown in Figure 4, clothing moisture reduces gradually along with the carrying out of dehydration, therefore the words that draining pump works always are allowed, some time internal drainage pump is anhydrous row, or the water deviate from can not meet the Minimum requirements of draining pump, and now very large noise will occur draining pump.In order to avoid this situation, this programme controls the running time of draining pump, and make its work a period of time stop a period of time, when the water deviate from puts aside certain amount, draining pump just operates, and avoids idle running to produce noise, reaches the object reducing noise.Concrete scheme is: need to control the working time of draining pump in the dehydration of 105 steps, as shown in Figure 2, step is as follows,
501, draining pump works on one T1 period after water discharges, described T1≤10 second;
First after washing procedure of washing machine terminates and discharged water, start draining pump work 10 seconds, to be discharged by ducted surplus water, this working time can adjust depending on concrete condition.
502, after electric motor starting dehydration procedure, draining pump so that the T2 time is run, mode alternation that the T3 time stops 30 seconds, described T2≤10 second, T3≤5 second;
Owing to being small washing machine, the laundry amounts of cleaning is little, and be mostly some socks, towel and so on, its moisture is also little, what therefore the working time of this draining pump set can not be very long, this programme is in units of 5 seconds and 10 seconds, and carry out alternately stoppage in transit 30 seconds, the concrete time can optionally adjust.
503, then draining pump stops to motor with the mode alternate run that the T3 time is run, the T2 time stops within the motor dewatering work time always; Also the height of water level can be judged by level sensor, the opening water discharge pump drainage again when the water thrown away reach a certain height, opening water discharge pump 5 seconds again at the end of dehydration, as much as possible discharges water remaining on bucket wall during high speed dewatering, reaches to reduce mould and produce object.When this period of duration of runs dewaters with motor, the working time is consistent, ensures that the water deviate from can be discharged in time.
504, draining pump reruns the T1 time after motor stops.
This step is to prevent washing machine internal water accumulation, draining pump in 503 also can be prevented finally just in time to be in halted state and make to also have water not discharge in washing machine.
