Fig. 8 is the block diagram of the electric formation of this drum type drying and washing machine 1 of expression.

The run action of this drum type drying and washing machine 1 is controlled by the control part 40 that for example microcomputer constitutes.Control part 40 possesses for example CPU, RAM, ROM etc.

With regard to control part 40, except the signal of input, also import signal from level sensor S3 and temperature sensor S4 etc. from above-mentioned exhaust gas temperature sensor S1 and dehumidifying water temperature sensor S2.Level sensor S3 sends signal when the water of storing reaches predetermined water level in the water jacket 7.In addition, temperature sensor S4 is mounted in the thermistor on the control basal plate of configuration example such as control part 40, and the external temperature of its external groove 7 detects, and sends signal according to detected result.

On control part 40, for example connecting water-supply valve 13, draining valve 18, dehumidifying water valve 14, drum driven motor 12, blower motor the 35, the 1st drying heater 341 and the 2nd drying heater 342 etc. as the control object.Control part 40 opens and closes water-supply valve 13 and draining valve 18 according to the signal from level sensor S3, can make the water level in the water jacket 7 be in required water level thus.In addition, control part 40, by making either party's energising of the 1st and the 2nd drying heater 341,342, can make the air themperature of sending in the cylinder 10 lower (more weak state), simultaneously, the two is all switched on by making the 1st and the 2nd drying heater 341,342, can make the air themperature of sending in the cylinder 10 higher (strong state).

The timing chart of the run action content when Fig. 9 is explanation final dewatering stroke.

In this embodiment, as the final dewatering stroke of terminal stage of dehydration stroke the time, can send in the cylinder 10 hot blast and dewater (thermal dehydration) by drying unit 3.At the final dewatering stroke, at first, dehumidifying water valve 14 is only opened the stipulated time (for example 60 seconds), and dehumidifying water is stored in water reservoir 73 (T1～T2).Therebetween, the 1st drying heater the 341, the 2nd drying heater 342 and blower motor 35 are in disconnection (OFF) state, water-supply valve 13 is in closed condition, use motor 12 (cylinder 10) only with the low speed and reverse of stipulated time by drum driven, make the washings in the cylinder 10 that lifts by baffle plate 10B freely fall (patting dehydration) from a certain height.The temperature that is stored in the dehumidifying water in the water reservoir 73 is detected by dehumidifying water temperature sensor S2, and its result (temperature data of dehumidifying water) is stored in the control part 40.

Dehumidifying water valve 14 cuts out (T2), and blower motor 35 just begins to drive, and reaches about 4500rpm (T3) at for example 5 seconds the rotating speed of this blower motor 35 of time.At this moment, the 1st drying heater 341 is connected (ON), and making the driving of drying unit 3 thus is weak state, and thermal dehydration is begun.

In the thermal dehydration process, the temperature of (in the water jacket 7) is lower in the cylinder 10, therefore, dehumidifying water is supplied to the temperature that can hinder in the cylinder 10 in the drying unit 3 rise.In this embodiment, dehumidifying water valve 14 remains on closed condition in the thermal dehydration process, and the temperature in the cylinder 10 is risen in order.When the drying stroke of carrying out thereafter begins, owing to the temperature that can improve preferably in the cylinder 10, therefore can improve drying efficiency, shorten the drying stroke required time.In addition and since be in the thermal dehydration process with warm-air supply to cylinder 10 in and dewater, so can improve dewatering efficiency.

When thermal dehydration begins (T3), for example, drum driven only in the counter-rotating of the short period of regulation, is being opened processing (opening dehydration) with motor 12 to the washings in the cylinder 10, then, drum driven is just changeing and is maintaining the rotating speed (the 1st dehydration starts) of about 150rpm with motor 12.Through just the walk around speed further raising of (T4) drum driven after the stipulated time with motor 12, reach about 400rpm (T5), drum driven descends gradually with the rotating speed of motor 12 and stops (the 1st high speed dewatering).When drum driven begins to descend with the rotating speed of motor 12 (T5), the 2nd drying heater 342 is connected (ON), and thus, any of the 1st and the 2nd drying heater 341,342 is for connecting (ON) state, and the driving that can make drying unit 3 is strong state.

When the 1st high speed dewatering finishes, just change repeatedly, reverse with the rotating speed of stipulating with motor 12, be attached to processing (the 1st clothing the is peeled off) (T6～T7) of the washings on cylinder 10 inner surfaces when being used to peel off the 1st high speed by drum driven.Thereafter, drum driven is reversed in the short stipulated time once more and is opened, dewaters with motor 12, and afterwards, drum driven is just changeing and keeping the speed (the 2nd dehydration starts) of about 150rpm with motor 12.

Further improve through the rotating speed of (T8) drum driven after the stipulated time with motor 12 positive veers, reach about 700rpm (T9), at this moment drum driven is kept (T10) after the stipulated time with motor 12 with this rotating speed, drum driven descends gradually with the rotating speed of motor 12, stops (the 2nd high speed dewatering) then.From the 2nd high speed dewatering (T8) to drum driven with the rotating speed of motor 12 begin to descend during (T10), the 1st drying heater 341 is for disconnecting (OFF) state.That is, and during this period (T8～T10), only by making the 2nd drying heater 342 be in connection (ON) state, the driving of drying unit 3 just can become weak state, after during this period, make the 1st drying heater 341 be in connection (ON) state again, then the driving of drying unit 3 is strong state.

When the 2nd high speed dewatering finishes, just change repeatedly, reverse with the rotating speed of stipulating with motor 12, be attached to processing (the 2nd clothing the is peeled off) (T11～T12) of the washings of cylinder 10 inner surfaces when being used to peel off the 2nd high speed dewatering by making drum driven.Thereafter, drum driven is reversed in the short stipulated time once more and is opened, dewaters with motor 12, and afterwards, drum driven is just changeing and keeping the rotating speed (the 3rd dehydration starts) of about 150rpm with motor 12.

Further improve with the rotating speed of motor 12 through (T13) drum driven after the stipulated time to positive veer.When drum driven reaches about 1100rpm (T14) with the rotating speed of motor 12, drum driven keeps (T15) after the stipulated time with motor 12 with this rotating speed, drum driven improves with the rotating speed of motor 12 and only rotates (T16) at the appointed time with the rotating speed of about 1200rpm, afterwards, drum driven descends gradually with the rotating speed of motor 12, stops (the 3rd high speed dewatering) then.From the 3rd high speed dewatering (T13) to drum driven with the rotating speed of motor 12 begin to descend during (T16), the 1st drying heater 341 is for disconnecting (OFF) state.That is, and during this period (T13～T16), only by making the 2nd drying heater 342 be in connection (ON) state, the driving of drying unit 3 just can become weak state, after during this period, make the 1st drying heater 341 be in connection (ON) state again, then the driving of drying unit 3 is strong state.

In this embodiment, during the 3rd high speed dewatering, particularly drum driven with motor 12 with the rotating speed of about 1100rpm just changeing during (T14～T15), water-supply valve 13 is only opened the stipulated time (for example 10 seconds).According to this formation, supply to water in the water jacket 7 and contact with the side face of cylinder 10 in rotating at a high speed and disperse in whole water jacket 7, this water that disperses can be removed attached to the detergent ingredients (bubble) on water jacket 7 and the cylinder 10.

When the 3rd high speed dewatering finishes, just change repeatedly, reverse with the rotating speed of motor 12 by making drum driven with regulation, enforcement is attached to processing (the 3rd clothing the is peeled off) (T17～T18) of the washings of cylinder 10 inner surfaces when being used to peel off the 3rd high speed dewatering, then, the 2nd drying heater 342 is closed (OFF), and final dewatering stroke (dehydration stroke) finishes.

In this embodiment, when being maintained at high speed as rotating speed at high speed dewatering accelerating period and cylinder 10, drum driven bigger with the drive current of motor 12 during (T8～T10, T13～T16), the driving that makes drying unit 3 is weak state, can suppress drying unit 3 (the 1st and the 2nd drying heater 341,342) consumed current.Thus, can prevent that the employed magnitude of current from surpassing setting the in service of drum type drying and washing machine 1, thereby can prolong the life-span of each parts that constitutes drum type drying and washing machine 1.

In this embodiment, can to make the driving of drying unit 3 be weak state by connecting one of (ON) the 1st and the 2nd drying heater 341,342, and by connection (ON) the 1st and the 2nd drying heater 341,342 the two can to make the driving of drying unit 3 be strong state.Thereby, as make the 1st drying heater 341 identical with the 2nd drying heater 342 for the time of connecting (ON) state for the time of connecting (ON) state, when the 1st and the 2nd drying heater 341,342 on/off (ON/OFF) are advanced to make up, can make the life-span equalization of each drying heater 341,342.Thereby further prolonged the life-span of drying unit 3.

The driving of drying unit 3 be strong state during (T5～T8, T10～T13), be preferably about more than 200 seconds.During this period, drum driven maintains about 150rpm with the rotating speed of motor 12, carry out such processing, promptly, the processing that the eccentric load that is caused by the washings deflections in the cylinder 10 is suppressed, such processing can be that moment below the setting, (T8 T13) entered high speed dewatering at eccentric load.In this case,, high speed dewatering can be do not entered, only just high speed dewatering can be entered through the described stipulated time even eccentric load when to be setting following is a strong state when beginning not pass through the stipulated time (for example about 20 seconds) from the driving of drying unit 3.

The timing chart of the run action content when Figure 10 is the explanation drying stroke.

When dehydration stroke (final dewatering stroke) finishes, just carry out drying stroke.Drying stroke comprises: and during beginning delivery temperature and the prebake of rising gradually of dehumidifying coolant-temperature gage by drying stroke (T19～T23); During the constant speed oven dry of delivery temperature and dehumidifying coolant-temperature gage difference constant (T23～T25); Delivery temperature (the T25～T26) that rises gradually, dehumidifies during the deceleration oven dry that coolant-temperature gage descends gradually.

During drying stroke (during the prebake) beginning (T19), the 1st drying heater 341 that is on-state (ON) state when the final dewatering stroke finishes is maintained at on-state (ON) state, the draining valve 18 that is in open mode also is maintained at open mode, simultaneously, dehumidifying water valve 14 is opened, and supplies with dehumidifying water in drying unit 3.At this moment, the rotating speed of about 4500rpm of blower motor 35 drops to the regulation rotating speed.

In addition, when the prebake stroke began, drum driven was with motor 12 (T19～T20) just change with the regulation rotating speed only at the appointed time.By the moment of inertia of cylinder 10 is during this period measured, can detect the amount (load capacity) of washings.Afterwards, drum driven was just being changeed 60 seconds with the rotating speed of motor 12 with about 50rpm, stopped then 3 seconds, and then the rotating speed with about 50rpm reversed 60 seconds, stopped 3 seconds again, and described action is carried out repeatedly.

Drum driven with motor 12 after the above-mentioned just commentaries on classics of the carrying out repeatedly/counter-rotating action (T20) through the stipulated time, at this moment, by making the 2nd drying heater 342 be on-state, promptly the 1st and the 2nd drying heater 341,342 is connection (ON) state, and the driving of drying unit 3 can be switched to strong state by weak state.Then, the rotating speed of blower motor 35 improves (T22) gradually, maintains the rotating speed of about 4500rpm again.

During prebake, delivery temperature and dehumidifying coolant-temperature gage raise gradually with roughly the same ratio.Through behind the certain hour, delivery temperature and dehumidifying coolant-temperature gage become constant, enter (T23) during the constant speed oven dry.During the constant speed oven dry, the the 1st and the 2nd drying heater 341,342 is for connecting (ON) state (driving of drying unit 3 is strong state), the rotating speed of blower motor 35 is maintained at about 4500rpm, simultaneously, in drying unit 3, supply with dehumidifying water by dehumidifying water valve 14 is opened, can dry washings effectively.In addition, in drying course,, raise gradually with certain low ratio (than delivery temperature during the prebake and the low ratio of dehumidifying coolant-temperature gage) with the detected room temperature of temperature sensor S4.

From drying stroke (T19) the process stipulated time (for example 90 minutes), drum driven was stopped 3 seconds after just changeing 60 seconds with the driving of motor 12 with the rotating speed of about 50rpm, and then the rotating speed with about 40rpm reversed 180 seconds, stopped again 3 seconds, and switched as above action (T24) repeatedly.This drum driven is maintained to drying stroke end (T26) with the type of drive of motor 12.Switch the timing of drum driven, determine according to load capacity, room temperature and the dehumidifying coolant-temperature gage etc. of for example washings with the type of drive of motor 12.

Like this, specified time limit before drying stroke finishes (T24～T26), the rotating speed of cylinder 10 (drum driven with motor 12) reverse directions is switched to than the slow-speed of revolution, simultaneously, the switching time of the reverse directions rotation of cylinder 10 is longer, therefore, can reduce to act on power on the washings in this cylinder 10 because of the switching of the direction of rotation of cylinder 10.Thus, can suppress to result from the torsion on the washings, reduce the wrinkle that produce on the washings well.

When too reducing the rotating speed of cylinder 10, the centrifugal force that acts on the washings in the cylinder 10 will diminish, and especially in the more occasion of the amount of washings, send passage 821 washings of hot blast to cover in cylinder 10 by drying unit 3.At this moment, the hot blast that drying unit 3 is sent here will have the anxiety that washings is dried well from the clearance leakage of labyrinth type rib 827,828.

In addition, as mentioned above, in this embodiment, make the occasion of cylinder 10 counter-rotatings make the air in the water jacket 7 enter exhaust outlet 71 than the occasion of just changeing is easier, therefore, when cylinder 10 is just changeing, will variation towards flowing of the hot blast of exhaust gas temperature sensor S1, delivery temperature is uprised.In this occasion, when cylinder 10 is just changeing and the exhaust temperature error in when counter-rotating become big, have the anxiety that washings is dried well.

Therefore, in this embodiment, the specified time limit before drying stroke finishes, (T24～T26), only the air in water jacket 7 entered the rotating speed of direction (reverse directions) the reduction cylinder 10 (drum driven motor 12) of exhaust outlet 71 easily, and prolongs rotational time.Washings is dried well.

But, when the load of washings reduces, be difficult on the washings producing wrinkle, therefore, when load does not reach setting, can not carry out above-mentioned control.

When washings is wet, be applied to heat (hot blast in the feed roller 10 and heat exchange amount between the washings) constant on the washings for transpiring moisture from washings, therefore also constant of delivery temperature, when washings is done, therefore the heat that is applied on the washings for transpiring moisture from washings is less, enters (T25) during the deceleration oven dry that delivery temperature uprises gradually.During the oven dry of slowing down, as mentioned above, supply to hot blast in the cylinder 10 and the heat exchange amount between the washings and diminish, and dehumidifying water supplies in the drying unit 3 with certain flow, and the dehumidifying coolant-temperature gage is reduced gradually.

In this embodiment, the delivery temperature (ceiling temperature) when determining that according to detected dehumidifying coolant-temperature gage and room temperature when the final dewatering stroke begins drying stroke finishes, (T26) drying stroke finishes when delivery temperature reaches ceiling temperature.Such formation makes the end of drying stroke not only will therefore can make the washings oven dry better according to the ceiling temperature that dehumidifies coolant-temperature gage but also will determine according to room temperature is also taken into account.In addition, because (therefore T1～T2) just the dehumidifying coolant-temperature gage is detected can detect the dehumidifying coolant-temperature gage before the hot blast of sending with drying unit 3 is heated to dehumidifying water during the 1st and the 2nd drying heater 341,342 is for disconnection (OFF) state.Thereby can determine more suitable ceiling temperature, so that dry washings better.

Figure 11 is dehumidify the relatively chart of corresponding relation of coolant-temperature gage and room temperature of expression ceiling temperature.

With reference to Figure 11, for example, as (WT＜10,10≤20,20≤WT＜30,30≤WT), ceiling temperature also are different value, and (KT＜10,10≤KT＜20,20≤KT＜30,30≤WT＜40,40≤KT), ceiling temperature also are different value for being different from 10 ℃ as room temperature KT for being different from 10 ℃ to dry the dehumidifying coolant-temperature gage WT that moves preceding (when the final dewatering stroke begins).More particularly, dehumidifying coolant-temperature gage WT is high more, ceiling temperature is set highly more, and room temperature KT is high more, ceiling temperature is set highly more.

Yet, dehumidifying coolant-temperature gage when ceiling temperature not only can begin according to the final dewatering stroke is determined, can also by for example when the final dewatering stroke begins and drying stroke the dehumidifying coolant-temperature gage is detected when beginning, and determine according to mean values of these dehumidifying coolant-temperature gages.

Refer again to Figure 10, in drying stroke (slow down oven dry during), when delivery temperature reaches ceiling temperature (T26), disconnect the 1st and the 2nd drying heater 341,342, drying stroke finishes, enter cooling stroke that washings is cooled off (T26～T28).

Interim at the cooling stroke, delivery temperature become with constant speed oven dry during delivery temperature roughly the same (temperature that cooling stroke detection of end arrives) (T27) before, drum driven was just being changeed 180 seconds with the rotating speed of motor 12 with about 40rpm, stopped then 3 seconds, then the rotating speed with about 40rpm reversed 180 seconds, stopped again 3 seconds, and as above moved repeatedly.During the cooling stroke, the rotating speed that can further improve blower motor 35 is to shorten the cool time of washings.

In addition, during the cooling stroke, draining valve 18 temporarily opens after cutting out certain hour, closes again, and described action can be used to carry out such processing, promptly discharges the end of a thread (discharging the end of a thread handles) of isolating and be stored in water jacket 7 bottoms from washings.In the processing that this end of a thread is discharged, make the dehumidifying water that is stored in water jacket 7 bottoms outside the end of a thread is discharged machine by draining valve 18 cutting out certain hour.

When delivery temperature drops to the detected temperatures (T27) of cooling stroke end, for example, be made as 2 minutes the remaining time of cooling stroke, simultaneously, drum driven was stopped 3 seconds after just changeing 30 seconds with the driving of motor 12 with the rotating speed of about 40rpm, and then the rotating speed with about 40rpm reversed 30 seconds, stopped again 3 seconds, and switched as above action repeatedly.

Like this, in the cooling stroke, drum driven just changeing with motor 12 (cylinder 10) and time of reverse by than the state of growing (180 seconds; T26～T27) enters short state (30 seconds; T27～T28).This formation can eliminate the winding of washings in cylinder 10, to launch well.Thereby can reduce the wrinkle that result from the washings preferably.

In the above-mentioned embodiment, only the occasion of carrying out drying stroke in washing (dehydration stroke) back is illustrated, but this drum type drying and washing machine 1 also can only be carried out drying stroke.In the occasion of only carrying out drying stroke, open the 1st drying heater 341, dehumidifying water valve 14 and draining valve 18 in the time of operation beginning (T19), so that the rotation of blower motor 35 drives beginning.

In the occasion of only carrying out drying stroke, can the temperature of the dehumidifying water of (for example 5 minutes) supply in the stipulated time of drying stroke (T19) be detected, and according to this dehumidifying coolant-temperature gage decision ceiling temperature.In this occasion, the 2nd drying heater 342 be closed condition (OFF) during (T19～T20), promptly, when the driving of drying unit 3 is weak state, detect this formation of dehumidifying coolant-temperature gage, can before the hot blast of being sent by drying unit 3 heats dehumidifying water, just detect the temperature of dehumidifying water.Thereby can determine more suitable ceiling temperature, so that dry washings better.

In addition, in the above-described embodiment, the formation that drying stroke finishes when reaching ceiling temperature for delivery temperature, the cooling stroke begins is illustrated.But, for example, also can be after delivery temperature reaches ceiling temperature, cylinder 10 rotates the stipulated time again so that hot blast is sent in the cylinder 10 (prolongation drying stroke).

In addition, in the above-described embodiment, only the formation that the ceiling temperature of determining according to dehumidifying coolant-temperature gage and room temperature is finished drying stroke is illustrated, but also can be that temperature difference at delivery temperature and dehumidifying coolant-temperature gage is the moment end drying stroke more than the setting.

With regard to drum type drying and washing machine in the past, standard is: oven dry capacity (for example 4.5kg) is below about 6 one-tenth of washing capacity (for example 8kg), perhaps, cylinder volume (for example being 66.6 liters) is about more than 14 with the volumetric ratio (drum capacity/oven dry capacity) of oven dry capacity (for example 4.5kg), and according to the drum type drying and washing machine 1 with above formation, oven dry capacity (for example 6kg) is about 7.5 one-tenth of washing capacity (for example 8kg), and volumetric ratio is about 11.That is, can dry more washings effectively.

The present invention is not subjected to the restriction of the content of above embodiment, can be the various distortion in the scope of technical scheme record.

For example, the axis of cylinder 10 is not limited to left and right directions and extends, and for example also can be the structure of extending along fore-and-aft direction.In this occasion, the axis of cylinder is not limited to extend along horizontal direction roughly, also can tilt in predetermined angular scope (for example 30 degree) with respect to horizontal direction.

The invention that relates to the supply of dehumidifying water also is not limited to drum type drying and washing machine, for example also is applicable to the pulsating drying and washing machine with clothing drying function.
