Description

Twin tube washing machine

The present invention relates to the twin tube washing machine that controlled the duration of runs of expelling water and rinsing running and dehydration running.

Twin tube washing machine, its washing running are to carry out in different washing tanks and dehydration cylinder respectively with expelling water and rinsing running, dehydration running, and be the judgement with the user their duration of runs, sets arbitrarily respectively one by one.

Occasion set the duration of runs with such method because the Best Times of washing operation time not only depends on the amount of substrate, and depends on dirty degree, so should set according to user's judgement based on this.And expelling water and rinsing running and dehydration running be because be to carry out for removing dirty substrate, decides so be amount according to substrate their duration of runs fully.

But, because expelling water and rinsing running in the past also is to set arbitrarily according to user's judgement with the duration of runs of dehydration running, so often do not conform to the quantity of substrate the duration of runs of setting, if the duration of runs is too short, will produce the unfavorable condition of residual washing agent and moisture in fully rinsing and dehydration, the substrate, on the contrary, if the duration of runs is long, then not only waste power and water, and can damage substrate.

The objective of the invention is to eliminate the unfavorable condition in the above-mentioned example in the past, and provide a kind of washing machine, this washing machine is by shirtsleeve operation, just can be with the optimum operation time that conforms to the amount of substrate, carry out expelling water and rinsing running and dehydration running, the efficient of laundry operation can be improved, also power and water can be saved.

Main points of the present invention are, in order to achieve the above object, and the inertia rotating speed during with the sensor washing procedure with the output of this sensor, is automatically set the duration of runs of expelling water and rinsing and dehydration procedure.

According to the present invention, utilization is installed in load transducer on the washer motor and detects inertia rotating speed after washer motor stops when the washing running, decide the dehydrating rinse process that then carries out and the duration of runs of rinsing process after the washing according to this inertia rotating speed, and the running of automatically carrying out expelling water and rinsing and rinsing the duration of runs to conform to the amount of substrate.

Below, describe embodiments of the invention with reference to the accompanying drawings in detail.

The 1st figure be in the methods of the invention employed load transducer vertically analyse and observe front elevation, the 2nd figure is the whole oblique view of the used twin tube washing machine of the present invention, the 3rd figure be above-mentioned twin tube washing machine vertically analyse and observe front elevation.If the unitary construction from twin tube washing machine begins to describe earlier, then among the figure, (1) is the washing tank that central authorities are provided with agitator (2), (3) expression is by at the vertical dehydration cylinder that is provided with the dehydration basket (5) of water tube (4) and surrounds Storage water tank (6) formation of this dehydration basket (5) of central authorities, and they all are arranged in the shell (17).

And, below in above-mentioned washing tank (1), be provided with washer motor (7), motor reel (8) passes through belt pulley (10), (11) respectively with the rotating shaft (9) of agitator (2), be connected to each other with V-shape belt (12), in addition, the below in Storage water tank (6), be provided with dehydration motor (13), the axle of dehydration motor (14) is connected with the dehydrating shaft of giving prominence to outside dehydration basket (5) (16) by shaft coupling (15).

In addition, in the front portion, upper end of shell (17), control panel (18) is installed.On this control panel (18), as an example, for example shown at (4) figure, be provided with switch (19) and (20) of power connection and disconnection usefulness, switch (21) and (22) that " washing " and " water rinsing " operation or " water filling rinsing " operation are selected and used for the duration of runs of setting them, the indicator lamp (23) of representing this duration of runs, the selector switch (24) of " expelling water and rinsing " operation, standard running and the indicator lamp (25) of careful running and the selector switch (27) of (26) and " dehydration " operation of this " expelling water and rinsing ", indicate indicator lamp (28) of this duration of runs or the like.The back side in this control panel (18) is equipped with the application control device (29) of known microcomputer etc. in the past.In this control device (29), storing the duration of runs and the drive manner of each operation, operation signal from above-mentioned each switch (19)-(22), (24), (27) is transfused to this control device (29), and drives the output signal of usefulness to the input of washer motor (7) and dehydration motor (13).

In the twin tube washing machine that constitutes like this, shown in the 1st figure, load transducer (30) has been installed in the bottom of washer motor (7).An example of this load transducer (30), what for example utilize is the device of the tachometer generator of following formation, promptly protrude in motor reel (8) outside the motor (7) around mounting permanent magnet (31), with this permanent magnet (31) leave slightly at interval around around last winding (32).Lead (33) is continued on this winding (32), and the other end is connected with above-mentioned control device (29).

Also have, the installation position of load transducer (30) of using this tachometer generator is except the occasion of above-mentioned motor (7), and the rotating shaft (9) of agitator (2) etc. also can.

Then, to using above-mentioned twin tube washing machine to come the method that control the duration of runs of dehydrating rinse process and dehydration procedure is automatically described.

Will wash running before entering dehydrating rinse process, in this operation, washer motor (7) is intermittently switched on, and the start of just changeing repeatedly, stop, reversing and stop to make alternately rotation about agitator (2).Between forward and reverse,, its objective is that motor (7) does not afford load in order to make counter-rotating or positive turn-off during the beginning subsequently so washer motor (7) is temporarily stopped.And for example 3 pulses [1 pulse is exactly that motor (7) rotates week] of initial energising to washer motor (7), predetermined set is in the storage part of control device (29).

Then, after in washing tank (1), putting into substrate and washing agent and water supply, if press the switch (20) that power supply " leads to ", then press the words of the selector switch (21) of " washing ", because the effect of control device (29) makes energising in the washer motor (7), the back energising of 3 week of rotation earlier once was cut off.

At this moment, washer motor (7) is even energising has been cut off, because inertia also can continue rotation, because this is rotated in and produces voltage in the winding (32), the signal of this alternating voltage enters control device (29) by lead (33), in control device (29), when in a single day the level of this alternating voltage reaches institute more than the definite value, promptly rotated for 1 week, read as 1 pulse as motor (7).

Like this, the inertia pulse comes instrumentation by control device (29), and this inertia umber of pulse will be according to the difference of the amount of substrate and different, and the amount of its numerical value and washings is inversely proportional to, it is after decision washer motor (7) stops, the judgement key element of the electrical pulse number when next time beginning to rotate.

In the present invention, specially for this inertia umber of pulse is divided into 3 for example following rank: 0-4 pulses as " full load ", the conducts " underload " more than the conduct of 5-7 pulse " middle load ", 8 pulses, and input control device (29), temporarily be stored in its storage part.

The storage of above-mentioned inertia umber of pulse is, if carry out primary " washing " running, then be stored in the dehydration side earlier, carry out if do not do " rinsing " secondary " washing ", then inertia umber of pulse at this moment is stored in the washing side, if remake the 3rd time " washing ", then the storage of the 1st time dehydration side is disengaged, and the signal that is stored in the washing side in the time of the 2nd time will be transferred to the dehydration side, and the inertia umber of pulse when the 3rd time " washing " is deposited in the washing side.

Like this, the electrical pulse number according to by the decision of inertia umber of pulse rotates and reverse washer motor (7) repeatedly and washs running, and washing running one finishes, and just carries out the transition to down " expelling water and rinsing " and " dehydration " operation together.

This " expelling water and rinsing " reaches " dehydration " operation and is divided into " standard running " and " careful running " two classes in the present embodiment, each running is according to " full load ", the division of " middle load " and " underload " of aforementioned inertia umber of pulse, shown in the 5th figure, the 6th figure, further be divided into again " by force ", " in " and " weak " three classes.

Substrate is taken out from washing tank (1), put into the dehydration basket (5) of dehydration cylinder (3), if press the once switch (24) of automatic rinsing, just automatically be chosen as " standard running ", and can automatically select the running that is consistent with the inertia umber of pulse that when last stage " washing " turns round, is stored in the side of dewatering.For example the amount of substrate is a lot, what the inertia umber of pulse when " washing " was deposited in is the words of " 3 ", just select " by force " running, to dehydration motor (13) and feed water valve (having omitted among the figure) energising, supplied water 15 seconds to water tube (4) earlier, from spraying water to dehydration basket (5) here, meanwhile, after dehydration motor (13) rotated for 50 seconds, in continuous water supply, dehydration motor (13) then stopped 1 minute 10 seconds, rotation ground 5 circulations repeatedly so altogether in 50 seconds.Carried out in this wise after " expelling water and rinsing " running, then automatically be filled into " dehydration " running of 3 minutes.And, when this state, lamp (25) and have the lamp (28) of the demonstration of " 3 " to light.

Above-mentioned is the occasion of selecting " standard running ".Select " careful running ", then just by twice switch (24), the same in this occasion also occasion with above-mentioned standard running, the inertia umber of pulse that deposits in when turning round according to " washing " automatically select shown in the 6th figure " by force ", " in ", some in the running of " weak ", and abide by the mode of storing and automatically carry out the running of " expelling water and rinsing " and " dehydration ".

Again, these " expelling water and rinsings " and " dehydration " running, also can be set at the running that to select arbitrarily except the running of automatic selection, for example, when only wanting the duration of runs of " dehydration " after changing " expelling water and rinsing " finishes, or when wanting to end " dehydration " running, the switch (27) of pressing the dehydration demonstration carries out map function.Now exemplify an example of this map function, for example, during lamp " 28 " the some light yellow of indication " 3 " minute, if by a switch (27), dewatering time just is transformed into " 1 " minute, if by twice, do not carry out with regard to only carrying out " expelling water and rinsing " " dehydration ", if by 3 times, then be transformed to " 5 " minute.

In addition, if press the switch (19) that power supply disconnects usefulness before entering " expelling water and rinsing ", then because the storage of inertia umber of pulse can be eliminated, if so it is under this state, by the switch (24) of automatic rinsing, then " standard " and " careful " running all can be with the starting of " by force " running, further, when wanting to end halfway " expelling water and rinsing " running, as long as be set at the switch (24) of rinsing automatically by three times.

,, change the energising of dehydration motor (13) and the cycle-index that stops like this, set the optimum operation time of " expelling water and rinsing " and " dehydration " with this along with the variation of load according to the inertia umber of pulse that when " washing " turns round, deposits in.Yet the setting of this optimum operation time except such change cycle-index, also can be considered by changing the rotating speed of dehydration motor (13), or the time that changes 1 circulation carries out.

As mentioned above, twin tube washing machine of the present invention is because can be automatically being set at the Best Times that conforms to the amount of substrate the duration of runs of " expelling water and rinsing " and " dehydration ", so can be because of rinsing deficiency or not enough washing agent or the moisture of in substrate, staying of dehydration Can not make wash time elongated because of excessive running yet, or waste power and water, therefore can improve the efficient of laundry operation.

And, just enough by pressing the such shirtsleeve operation of console switch because the setting of this duration of runs needs only, so use very convenient.
