Row, draining, intermediate dehydrating operation, water supply, rinsing operation (water storage rinsing), draining, final dewatering operation.Specifically, carrying out
Control as follows.
It is referred to as washing stroke until from above-mentioned washing weight detection (step S1) to operation (step S6) of loosening, separately
Outside, the draining (step S7) after operation of and then loosening is referred to as rinsing stroke until rinsing runs (S10), in addition,
And then the draining (step S11) after rinsing operation and final dewatering operation (step S12) are referred to as final dewatering stroke.
The weight (washing weight detection unit 25b) of washings is detected in step sl.It is detected in the washing weight
In, make the rotation of stirring body 12 to certain electric power is assigned to motor 13 in the state that washings is accommodated in swivelling chute 7
Turn obtained from revolution, in the state that washings is not accommodated in swivelling chute 7 to motor 13 assign certain electric power from
And revolution obtained from rotating stirring body 12 is compared, and thus detects washing weight (weight).In water level settings etc.
Use the detection data.In addition, washing weight detection can also detect washings according to the electric current of flow direction motor 13
Weight.
Water supply is executed in step s 2.In the water supply, in the state of closing drain valve 16, feed water valve 28 is opened, from
And water of the supply for the specified amount of cloth quality detection into swivelling chute 7.
Execute cloth quality detection (cloth detection unit) in step s3.In the cloth quality detection, received in a certain amount of water
In the state of being dissolved in swivelling chute 7, certain electric power is assigned to motor 13, to make stirring body 12 rotate, and according to stirring body
The size of 12 revolution, the cloth for detecting washings is such as which of " thick and stiff ", " standard ", " softness " three grades.
The detection data is used in setting of the degree of strength of water flow etc..
Water supply is executed in step s 4.In the water supply, in the state of remaining off drain valve 16, into swivelling chute 7
Water is supplied, until reaching the water level (slurry position) of setting.
Washing operation is executed in step s 5.In washing operation, clutch 14 is configured to washing clutch shape
State.In washing operation, it is stored in swivelling chute 7 in water and under the non-rotary state of swivelling chute 7, makes motor 13 and stir
Mix the intermittently positive and negative rotation of body 12.The rotary mode (positive and negative rotation figure) of motor 13 is as shown in Figure 7.In this case,
It is that 1 second rotate in the forward direction, stopping in 1 second, reverse rotation in 1 second, 1 second rotary mode to stop is repeated.It is revolving as a result,
Washing water flow is formed in turn trough 7.
In washing operation, it is fed with detergent in advance in swivelling chute 7, therefore, washing operation is so-called washes
Wash agent washing operation.
It after washing operation, keeps washing clutch state constant, is transferred to step S6, execute operation of loosening.Such as
Shown in Fig. 8, in the operation of loosening, make motor 13 and stirring body 12 intermittently positive and negative rotation, and open and close draining
Valve 16.That is, as shown in figure 8, identical revolution when being run with washing, by the way that 0.6 second rotate in the forward direction, 0.6 second is repeated
Stopping, reverse rotation in 0.6 second, 0.6 second stop it is short-term between rotary mode driving motor 13.As a result, in swivelling chute 7
It is interior to form the loosen water flow slightly weaker than the washing water flow.In addition, rotary mode when relative to washing operation, loosens above-mentioned
It is lower when can also make the revolution of motor 13 in rotary mode when operation than washing operation.
Moreover, the water level in swivelling chute 7 becomes predetermined water level HO, is herein opposite as shown in (b) of Fig. 6 and Fig. 9
Water level (water supply when relative to washing operation of the regulated proportion of water level Hk (referring to (a) of Fig. 9) when washing operation
Water level Hk, for example, 1/3 or more predetermined water level HO) when (if in terms of the time, for period th1), drain valve 16 is closed,
In, the close lower limit water level Hz that can be brought to washings in the water level of buoyancy of the predetermined water level HO.As a result, in the fortune of loosening
During a part during capable execution in th, i.e. from the outset during in th1, open drain valve 16, and in remaining phase
Between drain valve 16 is closed in th2.
In above-mentioned operation of loosening, by running weak water flow (water flow of loosening) washings of loosening than washing, moreover, passing through
Water level is reduced, makes washings to moving below swivelling chute 7, and be generally uniform state in its insole portion cloth.
As shown in (b) of Fig. 9, when this loosens end of run, the water of predetermined water level HO is remained in swivelling chute 7.This
Outside, the variation of water level is as shown in Figure 6.
After this loosens end of run, it is transferred to step S7, opens drain valve 16, and by clutch 14 from washing clutch
Form is switched to dehydration clutch state.At the initial stage of the switching, the clutch spinning movement of the motor 13 is executed.?
The time point, due to remaining the water for the water level HO for making buoyancy in washings in swivelling chute 7, alleviate opposite
In the washings load of stirring body 12, and washings will not be attached on the stirring body 12 and swivelling chute 7.Therefore, by
The load that washings is applied to motor 13 is smaller, which rotates in the clear.Clutch 14 is in and suitably nibbles as a result,
Coincidence is set (rotatable phase), and clutch 14 is successfully switched to dehydration clutch state.
In addition, in the step s 7, the water being discharged in swivelling chute 7 by opening the drain valve 16.In this case, lead to
Above-mentioned operation of loosening is crossed, washings is generally uniform state in the insole portion cloth of swivelling chute 7, and therefore, washings keeps uniform
The constant inner bottom surface for sinking to swivelling chute 7 of state, and retain generally uniform state.
Next, being transferred to step S8, start intermediate dehydrating operation.
When executing intermediate dehydrating operation in step s 8, is carried out in dehydration rotation control control as follows: making swivelling chute 7
Revolution gradually rise with the progress of time.In this case, since the washings in swivelling chute 7 is in swivelling chute 7
Bottom retains generally uniform state, therefore unbalance rotation will not occur, to successfully be dehydrated.The centre for executing the stipulated time is de-
Drain valve 16 is closed in water running at the end.
It is transferred to step S9 after step s8, executes water supply.In the water supply, in the state for remaining off drain valve 16
Under, water is supplied into swivelling chute 7, until the water level (water storage rinsing water position) for reaching setting.Later, it is transferred to step S10,
Rinsing operation is executed with the stipulated time.Rinsing operation is so-called water storage rinsing washing.In rinsing operation, a certain amount of
Water be accommodated in swivelling chute 7 in the state of, make the intermittently positive and negative rotation of stirring body 12.In rinsing operation, pass through
The tap water rinse washings being stored in swivelling chute 7.The operation of loosening is not executed after rinsing operation.
Later, it is transferred to step S11, executes draining.In the draining, drain valve 16 is opened, the water in swivelling chute 7 is discharged.
In following step S12, final dewatering operation is executed with the stipulated time.Final dewatering operation makes swivelling chute 7 and stirs
The rotation of body 12 is mixed, to be dehydrated to washings.
End of run is washed as a result,.
Further more, control unit 25a during executing the main program, also executes control below with specific time interval
System.
In fig. 10 it is shown that setting the content of relevant control to the time.Control unit 25a judges in step T1
The no time setting switch 23a1 having to operation inputting part 23a is operated, if operated, in step T2
In judge whether in loosening during operation.Change when during being judged as in operation of loosening, without the time
More (step T3).If being "No" in step T2, it is transferred to step T4, carries out the change of time.
In fig. 11 it is shown that the content of control relevant to temporarily ceasing.Control unit 25a judges in step U1
It is no that the switch 23a2 that temporarily ceases that operation inputting part 23a has is operated and (temporarily ceased instruction), if it is "Yes",
Then judge whether in step U2 in loosen operation during.During being in operation of loosening, then step is transferred to
Rapid U3 stops operation of loosening, and temporarily ceases drain valve 16.Then, judge whether to operate again in step U4 temporarily to stop
Only switch (whether thering is recovery to instruct).When being judged as has recovery to instruct, suspension is loosened operation, and be transferred to this loosen run it is subsequent
Control (in this case be draining movement).
If being "No" in the step U2, it is transferred to step U6, stops the operation or the movement.Then, when
It is judged as in step U7 and is operated when temporarily ceasing switch (have recovery instruct) again, is transferred to step U8, starts again at operation.
In fig. 12 it is shown that by operate temporarily cease switch other than mode (when detect it is certain exception when make to transport
Stop the case where function is acted when the exception that row stops) making the control run when stopping of loosening.In step V1, judgement is
It is no be loosen operation during stopped operation, if it is "Yes", judge whether in step V2 for example, by by with
The recovery processing that family carries out makes restoring running.If operation is resumed, stop the operation of loosening, and after being transferred to the operation of loosening
Continuous control.
In the above-described embodiment, the entire period that control unit 25a is not the th during the execution for operation of loosening beats
Begin to rehearse water valve 16, but is therefore closing drain valve 16 in period th2 is loosened at this during a part of th during execution
The time point of end of run also remains water in swivelling chute 7 other than washings is aqueous, as a result, even if washing
Under object is more and the heavier situation of overall weight, which will not be attached to and stir across stirring body 12 and 7 bottom surface of swivelling chute
It mixes on 7 bottom surface of body 12 and swivelling chute.As a result, stirring body 12 and motor 13 will not be locked up, it is switched to by clutch 14
When dehydration clutch state, the clutch spinning movement of motor 13 can be carried out in the clear.As a result, can
Postrun clutch switching of loosening is carried out by ground.
In addition, if drain valve 16 is initially all opened to the end from operation of loosening, when shortening the execution of the operation of loosening
Between, although then remaining water when loosening end of run, in this case, the execution time for operation of loosening is shorter, no
It can realize that the purpose of script is loosened effect.For this point, in the above-described embodiment, since operation of loosening will not be shortened
The time is executed, therefore effect of loosening will not be reduced.
In addition, in the present embodiment, in operation of loosening, control unit 25a make buoyancy in swivelling chute 7
Predetermined water level HO in the water level of washings closes drain valve 16, therefore can reduce the washings being applied on stirring body 12
Load can be such that washings is uniformly distributed well.Therefore, it can prevent in dehydrating operation (intermediate dehydrating operation) later
Unbalance rotation occurs, is successfully dehydrated so as to realize.
In addition, in the present embodiment, control unit 25a make buoyancy in the regulation of the washings in swivelling chute 7
Clutch 14 is switched to dehydration clutch state by water level HO, therefore, can when loosening the switching of postrun clutch
The washings load being applied on motor 13 is further decreased, so as to more reliably carry out the clutch switching.
In addition, in the present embodiment, control unit 25a opens drain valve 16 during the execution for operation of loosening in th
(period th1), and hereafter close drain valve 16 (period th2), therefore, with from operation of loosening initially to the end all open arrange
The case where water valve 16, is different, in the later period for loosening operation, carries out operation of loosening in the state of maintaining low water level to a certain degree,
Make effect raising of loosening.
In addition, in the present embodiment, control unit 25a can successively execute dehydrating operation (intermediate dehydrating operation) and drift
Operation is washed, does not execute operation of loosening after rinsing operation.
When carrying out rinsing operation after dehydrating operation, the state that flocks together sometimes in washings by dehydrating operation
Under carry out rinsing operation, in this case, when the rinsing operation after carry out low water level loosen run when, it is described to be gathered in
Washings together acts on motor 13 as biggish load, can not expect to obtain effect of loosening.
For this point, in the present embodiment, can not expect to obtain effect of loosening due to not executing after rinsing operation
Operation of loosening, therefore extra operation of loosening can be eliminated.
In addition, in the present embodiment, have the change for inputting runing time, change as the time it is single with input
The time setting switch 23a1 of member, even if carried out operation from time setting switch 23a1 in the implementation procedure for operation of loosening
Between the input changed, control unit 25a is also not bound by the input.
For example, even if extend the time setting for operation of loosening, due to being carried out with the water level lower than washing operation
The operation of loosening, therefore can not expect to obtain cleaning effect.In addition, when shorten the time setting for operation of loosening, nothing
Method is expected to obtain effect of loosening.
Therefore, in the present embodiment for being arranged to above structure, when running related operation due to being not bound by and loosening
Between change input, therefore, can eliminate can not expect to obtain cleaning effect, can not expect to obtain the runing time of effect of loosening
Change.
In addition, in the present embodiment, have for temporarily cease operation, it is temporary with input unit as temporarily ceasing
When shutdown switch 23a2, when making the operation of loosening by the input for temporarily ceasing switch 23a2 in the implementation procedure in operation of loosening
When temporarily ceasing, control unit 25a closes drain valve 16, after temporarily ceasing recovery, stops operation of loosening, and be transferred to this and loosen
Run subsequent control.
When temporarily ceasing in operation of loosening, when being added to washings, washings can be caused excessive in low water level, such as
Fruit directly starts again at operation of loosening when temporarily ceasing recovery, it is likely that will increase the load of motor 13, thus to loosening
Operation causes to hinder.
For this point, according to the present embodiment for being arranged to above structure, the row of closing when operation of loosening temporarily ceases
Water valve 16, temporarily cease restore after stop to loosen operation, and be transferred to this and loosen and run subsequent control, therefore, can prevent
Operation of loosening is caused to hinder because adding washings etc. when starting again at operation, so as to continue to do washing.
In addition, in the present embodiment, for example, while passing through exception stop function etc. detect it is abnormal in operation of loosening
Implementation procedure in make this loosen operation stop when (when stopping because of the reason of temporarily ceasing other than switch 23a2), control unit
25a stops to loosen operation after stopping restoring, and is transferred to this and loosens and run subsequent control, therefore, as described above, can
Operation of loosening is caused to hinder due tos adding washings etc. when running and stopping when preventing from starting again at operation, so as to continue
It does washing.
Figure 13 shows second embodiment, and in this second embodiment, control unit 25a is starting operation of loosening
When, drain valve 16 (continuing to close since washing operation) is closed in the state of water level Hk, wherein the water level
Hk, which is contained in, makes buoyancy in the water level of washings, then, during the execution for operation of loosening during initial in th
Th1 ', the continuously off drain valve 16, hereafter during drain valve 16 is opened in th2 '.Above-mentioned period th2 ' is set to:
In the execution end time point for operation of loosening, make in swivelling chute 7 described in residual can be brought to washings in the water level of buoyancy
During predetermined water level HO.Then, in the state of predetermined water level HO, clutch 14 is switched to dehydration clutch shape
State.
In this second embodiment, since control unit 25a is not the entire of the th during the execution for operation of loosening
Period opens drain valve 16, but is that drain valve 16 is closed in period th1 ' during a part of th during execution, therefore,
The time point of the end of run of loosening also remains water in swivelling chute 7 other than washings is aqueous, as a result, even if
In washings in the heavier situation of more and overall weight, which will not be attached across stirring body 12 and 7 bottom surface of swivelling chute
On 7 bottom surface of stirring body 12 and swivelling chute.As a result, stirring body 12 and motor 13 will not be locked up, by clutch 14
When being switched to dehydration clutch state, the clutch spinning movement of motor 13 can be carried out in the clear.As a result,
Postrun clutch switching of loosening can reliably be carried out.
Figure 14 shows third embodiment, and place is different from the first embodiment and is, in the third embodiment,
Step Sa has been added after step s 5.That is, control unit 25a detects to wash by washing weight detection unit 25b
When the weight of object is predetermined weight or more (judging result of step Sa is "Yes"), operation of loosening is executed, and is being less than regulation weight
The operation of loosening is not executed when amount.
In the case where washings more (overall weight is heavier), washings is gathered in one mostly when washing end of run
It rises, on the contrary, seldom flocking together in the case where washings is less.That is, loosening, to operate in washing weight heavier
When be effective, and be extra when washing weight is lighter.
In the third embodiment for considering this point, detect to wash by washing weight detection unit 25b
When the weight of object is predetermined weight or more, operation of loosening is executed, and does not execute operation of loosening when being less than predetermined weight, therefore not
Operation of loosening can vainly be executed.
In addition, for the movement for closing drain valve, it, can also be according to timing other than being closed according to water level detecting
The setting time of device is closed.
More than, although multiple embodiments of the invention are illustrated, these embodiments are as an example
It proposes, it is not intended that limit the protection scope of invention.These novel embodiments can be implemented with various other ways,
In the range of invention objective, various omissions, substitutions and changes can be carried out.These embodiments or its deformation are included in
