Control unit 40 controls the driving of motor 5, makes washing tube 4, the first rotating vane 6 and the rotation of the second rotating vane 7 as a result, or stop their rotation.In addition, control unit 40 controls clutch mechanism 28 in the case where clutch mechanism 28 above-mentioned is electronic, the driving force of motor 5 can be transmitted or cut off respectively as a result, to washing tube 4, the first rotating vane 6 and the second rotating vane 7.Detecting part 41 be to the revolving speed of motor 5, strictly be rotor (not shown) in motor 5 the composition that is sensed of revolving speed, such as be made of Hall IC.The revolving speed for the motor 5 that detecting part 41 is sensed is input to control unit 40 in real time.
Display operation unit 42 is set to the surface of casing 2, is made of switch, liquid crystal display panel etc..Control unit 40 receives operation of the user to display operation unit 42, and necessary information is perhaps shown in display operation unit 42 in energy visual mode or issues beep by display operation unit 42.Water unit 43 includes at least feed water valve 24 above-mentioned.Feed water valve 24 is opened and closed in control unit 40, supplies water into bucket 3 and in washing tube 4 as a result, or stops supplying water.Water level sensor 44 is the well known sensor sensed to the water level of the water level of bucket 3, i.e. washing tube 4.Drainage Division 45 includes at least drain valve 25 above-mentioned.Drain valve 25 is opened and closed in control unit 40, carries out the draining of bucket 3 and washing tube 4 as a result, or stop draining.
Then, it is illustrated in washing machine 1 by the washing operating that control unit 40 executes.Referring to the flow chart of Fig. 3, washing operating includes washing process (step S1), washs to the washings Q being contained in washing tube 4；Rinse cycle (step S2) rinses the washings Q after washing process；And it is de-
Water process (step S3) is dehydrated washings Q after rinse cycle.
Referring to Fig.1 with the flow chart of Fig. 4, washing process is illustrated.It is contained in washing tube 4 when user puts into washings Q from input port 18, and by being operable at the beginning of indicating washing operating to display operation unit 42, control unit 40 receives the instruction (step S11), senses the amount of the washings Q in washing tube 4 as load (step S12).Control unit 40 both can sense load by dedicated sensor (not shown), can also sense load according to the deviation for the revolving speed for for example making the motor 5 when the fixation rotation of washing tube 4.Control unit 40 obtains the respective specified amount of required detergent and tap water according to this load.These specified amounts are summarized according to load and are pre-stored within memory 47.The specified amount of detergent corresponding with this load is shown in display operation unit 42 by control unit 40.Exist in washing process: in the normal wash for supplying water into washing tube 4 to the specified amount determined according to this load, being cleaned to washings Q, and the concentration of the concentrated cleaning solution generated and detergent is dissolved to normal concentration in the tap water far less than specified amount having been used to clean.It should be noted that may include the instruction about whether the selection for carrying out concentration cleaning in the instruction from user in step s 11.
The control unit 40 for sensing load waits user to put into detergent (step S13).User prepares the corresponding detergent of specified amount of this determination using the display of display operation unit 42 as reference, opens door 11 and lid 8B is made to turn to open position, then puts into detergent in guidance road 37 from throw-in part 37A.Then, input detergent flows downward in guidance road 37, the space S (arrow of thick dashed line referring to Fig.1) being directed between the bottom wall 17 of washing tube 4 and the first rotating vane 6 as a result,.In this way, guidance road 37 is for guiding detergent to the through path of space S.Then, when user, which makes to cover, closes door 11 after 8B turns to closed position, the investment of detergent is completed.For control unit 40, when for example sensing the closing of door 11 by sensor (not shown), it is judged as and has put into detergent (being in step s 13 yes), starts to supply water (step S14) into bucket 3 and washing tube 4 by water unit 43.
When making the water level in washing tube 4 rise to the predetermined water level lower than the water level of specified amount above-mentioned by supplying water, space S and its around, complete concentrated cleaning solution above-mentioned, therefore, control unit 40 monitors whether to complete concentrated cleaning solution (step S15) based on the water level in washing tube 4.Predetermined water level herein refers to, such as is equivalent to 50% water level of the water level of specified amount.When completing concentrated cleaning solution, that is, when the water supply for carrying out being less than specified amount by this way when space S generates concentrated cleaning solution (being yes in step S15), control unit 40, which stops supplying water simultaneously starting to be concentrated, cleans (step S16).Specifically, being concentrated
Cleaning solution is accumulated in the state of space S, and control unit 40 rotates the first rotating vane 6 and the second rotating vane 7 by motor 5.
In concentration cleaning process, the washings Q in washing tube 4 on the first rotating vane 6 is contacted with the stirring blade 6A of the first rotating vane 6 rotated, is thus stirred.Furthermore, the blade 7B that pumps up water for the second rotating vane 7 that the concentrated cleaning solution of space S is rotated squeezes out to radial outside R2 and is fed through the entrance 38A on road 38 of pumping up water, and rises in road 38 of pumping up water and is sprayed to the washings Q (arrow of heavy line referring to Fig.1) in washing tube 4 from outlet 38B.It pumps up water in road 38 and is permeated when washings Q from the concentrated cleaning solution that 38B is recycled in washing tube 4 is exported when pumping (pump up) effect realized by the second rotating vane 7 in this way is drawn into from space S, the detergent ingredients that the dirt of washings Q is concentrated the high concentration in cleaning solution decompose.The concentrated cleaning solution permeated in washings Q flows downward to space S after washings Q exudation in washing tube 4.Concentrated cleaning solution road 38 and washings Q and is recycled in a manner of being back to space S by passing through to pump up water from space S as a result,.
It in concentration cleaning, is rotated by the first rotating vane 6 and the washings Q in washing tube 4 is stirred, therefore, washings Q is cleaned by the mechanical force from the first rotating vane 6.And, rotated to be higher than the speed of the first rotating vane 6 by the second rotating vane 7 and be sent into concentrated cleaning solution the entrance 38A on road 38 of pumping up water, as a result, concentrated cleaning solution on one side pass through road 38 of pumping up water recycle fiercely, while byed the washings Q being sprayed in washing tube 4 repeatedly.All washings Q are strongly cleaned by the detergent ingredients of the high concentration in concentrated cleaning solution as a result,.As a result, the raising of cleaning force can be sought brought by them.
Control unit 40 is monitored by timer 48 passes through the time from starting concentration cleaning.When from starting concentration cleaning by the first wash time (being yes in step S17), confirm whether the revolving speed of current motor 5 reaches egulation rotating speed (step S18) by detecting part 41.If the revolving speed of motor 5 is egulation rotating speed or more, the second rotating vane 7 is carrying out high speed rotation, and concentrated cleaning solution is recycled with the impetus for the degree that can fully clean washings Q as a result,.On the other hand, if the revolving speed of motor 5 is less than egulation rotating speed, the revolving speed of the second rotating vane 7 is low, and therefore, the impetus of concentrated cleaning solution is weak, according to circumstances can be in the state for not recycling and staying in space S.If the revolving speed of motor 5 is egulation rotating speed or more (being yes in step S18), control unit 40 continues concentration cleaning (step S19).Then, when from starting concentration cleaning by the second wash time (being yes in step S20), control unit 40 stops motor 5, thus terminates concentration cleaning (step S21).
After terminating concentration cleaning, the water storage in washing tube 4 of control unit 40 supplies water (step S22) as final until reaching specified amount above-mentioned.The remaining water for being equivalent to the difference of water supply and specified amount before starting final supply water as a result, is added into washing tube 4, and therefore, the concentration of the detergent in cleaning solution in washing tube 4 is lower than the concentration of the detergent in concentrated cleaning solution.Then, control unit 40 stops supplying water and starting normal wash, so that the first rotating vane 6 and the second rotating vane 7 is rotated (step S23) by motor 5.It in normal wash, is soaked in the first rotating vane 6 that the washings Q accumulated into a large amount of cleaning solution of specified amount is rotated and stirs, or the cleaning solution of the usual concentration recycled by the rotation by the second rotating vane 7 sprays, and is thus cleaned.Then, when from starting normal wash by third wash time (being in step s 24 yes), control unit 40 stops motor 5, thus terminates normal wash, therefore washing process is completed.
Wherein, the state that washings Q is sufficiently rinsed will become in the case where concentration cleaning proceeds to the second wash time according to the setting of the second wash time sometimes.Therefore, in the case where the revolving speed for the motor 5 being concentrated in cleaning process rises to egulation rotating speed (being yes in step S18), control unit 40 can be after the concentration of the stipulated time before continuing the second wash time cleaning (being yes in step S20), terminate washing process, and without finally supplying water (step S22) and normal wash (step S23 and S24).In this case, can seek it is water-saving in washing process, therefore, even if water supply is few, by be concentrated cleaning can also play maximum cleaning force.
It should be noted that control unit 40 carries out the draining of bucket 3 and washing tube 4 by Drainage Division 45 when completing washing process.In rinse cycle (step S2) after draining, control unit 40 is by the way that by tap water accumulation, in washing tube 4 and rotating the first rotating vane 6 and the second rotating vane 7 to generate water flow, therefore, the washings Q in washing tube 4 is rinsed by water flow.Rinse cycle can carry out repeatedly.When completing rinse cycle, control unit 40 carries out the draining of bucket 3 and washing tube 4 by Drainage Division 45.In dehydration (step S3) after draining, control unit 40 makes 4 high speed rotation of washing tube in the state of opening drain valve 26 of Drainage Division 45.The moisture in washings Q is oozed out by centrifugal force as a result, and thus washings Q is dehydrated.
On the other hand, mostly etc. due to the load of the washings Q in washing tube 4, washings Q can become the resistance of the first rotating vane 6, and the revolving speed that have passed through the motor 5 under the time point of the first wash time sometimes as a result, is insufficient and do not rise to egulation rotating speed.If so, the revolving speed of the second rotating vane 7 will not rise, accordingly, it is difficult to recycle concentrated cleaning solution fiercely and it is made to be sprayed to washings Q.Therefore,
In the case where the revolving speed of the motor 5 under the time point that have passed through the first wash time does not rise to egulation rotating speed (being no in step S18), control unit 40 cleans preset count value (step S25) referring to about concentration.
Count value is stored in memory 47, is the value for resetting to zero at the end of cleaning is concentrated, is incremented (+1) when the revolving speed of the motor 5 under the time point that have passed through the first wash time is less than egulation rotating speed.If current count value is less than preset specified values (being in step s 25 yes) such as " 3 ", then control unit 40 carries out increment to current count value, and it temporarily ceases motor 5 and interrupts concentration cleaning, the range that the water in washing tube 4 above-mentioned is not up to specified amount carries out additional water supply (step S26).That is control unit 40 carries out additional water supply as processing is retried in the case where the revolving speed for the motor 5 being concentrated in cleaning process does not rise to egulation rotating speed.
After additional water supply, control unit 40 restarts concentration cleaning (step S16), implementation steps S17 later processing after stopping supplying water.By additional water supply, rises in the range that the concentration of detergent of the water level in concentrated cleaning solution in washing tube 4 does not drop to more than required, therefore, washings Q can be made to float and reduce the burden of the resistance of the first rotating vane 6, i.e. motor 5.Therefore, by making the revolving speed for the motor 5 being concentrated in cleaning process rise to egulation rotating speed, 7 high speed rotation of the second rotating vane can be made.Although recycling fiercely in this case, can make to dilute concentrated cleaning solution some but that and then detergent is just dissolved into high concentration because of additional water supply, and it is made to be sprayed to washings Q.As a result, can also seek the raising of cleaning force even if keeping the incipient resistance of the first rotating vane 6 excessive because the washings Q in washing tube 4 is waited more.It should be noted that confirming whether the revolving speed that have passed through the motor 5 under the time point of the first wash time from restarting concentration cleaning reaches egulation rotating speed by control unit 40 in restarting the step S18 after concentration cleaning.
When the revolving speed of motor 5 do not reach egulation rotating speed after restarting concentration cleaning yet and final count value increase to 3 when (being in step s 25 no), control unit 40 is forced to terminate concentration cleaning (step S21), after finally water supply (step S22), implement normal wash (step S23).When the water supply that further progress adds in the case that the revolving speed of the motor 5 in the concentration cleaning process after additional water supply does not rise to egulation rotating speed, concentrated cleaning solution can be diluted to cannot be concentrated cleaning solution usual concentration, therefore, the effect of original concentration cleaning can be probably unable to get.Therefore, control unit 40 so stops concentration cleaning (step S21), carry out additional water supply, until the water in washing tube 4 reaches specified amount (step S22), the normal wash (step S23) for rotating the first rotating vane 6 and the second rotating vane 7 is then carried out.
The cleaning solution of usual concentration is dissolved to by the stirring of the rotation realization by the first rotating vane 6, detergent as a result, normal wash can be carried out to washings Q.Control unit 40 implements normal wash (being in step s 24 yes) before by during third washing, then terminates washing process.
The present invention is not limited to the contents of embodiment of above, and various modifications may be made in the range recorded in claim.
For example, washing machine 1 can be the clothes washer-dryer for having the function of drying washings Q.In addition, the vertical type that the central axis J that washing machine 1 is washing tube 4 in embodiment above-mentioned extends in above-below direction, but washing tube 4 is also configurable to central axis J and intersects with up and down direction.
