The fully automatic washer / dryer according to the embodiment described below is capable of performing washing (washing and rinsing), dehydration and drying, and will be described in detail later. A washing / dehydrating tub with an opening at the top that is rotatably installed around a vertical axis, and a large diameter stirring blade that covers most of the bottom of the washing / dehydrating tub is rotatably installed in this washing / dehydrating tub Then, a drive device for rotating or resting the washing / dehydrating tub and the stirring blade, a water supply / drainage unit, a blowing unit and a heating unit, and a control for controlling the drive unit, the water supply / drainage unit, the blowing unit and the heating unit. And a device.

The washing and drying machine will be described below, but since the washing and drying machine is a fully automatic washing machine except for the drying mechanism, an embodiment of the fully automatic washing machine will be omitted.

The stirring blade has a large diameter (the outer diameter dimension is equal to the inner diameter dimension of the washing / dehydrating tub 9 which covers most of the bottom of the washing / dehydrating tub).
(0% or more), it is bent upward so as to push up the peripheral portion to form a dish shape, and is configured to rotate while supporting the laundry.

The drive device includes a drive motor, a speed reduction mechanism, a switching clutch mechanism, and a clutch operating motor. The speed reduction mechanism is composed of a planetary gear mechanism to reduce the rotation of the drive motor to rotate the stirring blade. The switching clutch mechanism is operated by the clutch operating electric motor to drive the stirring blade in reverse while the washing / dehydrating tub is stationary. A second drive mode in which the stirring blade and the washing / dehydrating tank are rotationally driven in a state where the water tank is freely rotated and the driving force in the direction opposite to the stirring blade is applied to the washing / dehydrating tank by the driving reaction force of the stirring blade. The rotation of the electric motor is directly transmitted to the washing / dehydrating tub so that the washing / dehydrating tub and the stirring blade are switched to a third driving mode in which the driving electric motor integrally rotates.

The switching operation of each of the driving modes of the switching clutch mechanism is realized by swinging the clutch operating lever by the cam rotationally driven by the clutch operating motor, and the detection of each driving mode is performed by the cam. The position of the first drive form and the position of the third drive form are respectively detected by two position detection switches, and the second drive form is estimated by the rotational drive elapsed time from the state detected by the position detection switch. It is configured to be performed by doing.

Further, the high-concentration detergent liquid generating / supplying means descends and sinks the high-concentration detergent liquid having a detergent concentration of 5 to 30 times as much as the washing water generated by dissolving the powder detergent into tap water. It is a configuration that allows.

The blower means and the heating means are constructed so that the moist air in the outer tub is sucked out, dehumidified with water and then heated and blown into the washing / dehydrating tub.

Then, the control device executes the following control processing.

First, when the power is turned on, the switching clutch mechanism initialization control for driving the clutch operating electric motor is performed so that the switching clutch mechanism is in the second drive mode. In this second drive mode, the process executed thereafter is
In general, since the drive mode is the same as that for detecting the amount of laundry, the initialization state is suitable for reducing the occurrence of delay time in the progress of the process.

Next, when the start switch is pressed after the initialization setting operation, and when general automatic washing is set, the stirring blade is rotated with the switching clutch mechanism in the second drive mode. By this, the amount of laundry put in the washing and dehydration tub can be detected (detergent amount sensing)
To set a suitable amount of washing (washing and rinsing) water, and to set the amount of detergent (generally, the amount of the powdered synthetic detergent input) for producing washing water having a desired detergent concentration according to the set amount of water. ,indicate. In the detection of the amount of laundry in the second drive mode, it is possible to eliminate the influence of the unstable behavior of the switching clutch mechanism and realize highly accurate detection.

Next, the washing / dehydrating tub and / or the stirring blades are rotated to drop water on the laundry to wet it and reduce its bulk, and it is suitable for descending a high-concentration detergent liquid to be immersed therein. State.

When the set amount of the powdered detergent is added to the detergent feeding means, the powdered detergent is dissolved in a small amount of detergent-dissolving water to produce a high-concentration detergent liquid, and the high-concentration detergent liquid is generated. The chemical washing power of the high-concentration detergent liquid acts on the dirt by sinking the water into the laundry and immersing it in the laundry, and then the mechanical washing power (the stirring blade and the washing / dehydrating tank acts on the laundry). By reducing the mechanical force to be applied, it is possible to reduce the damage to the cloth and the entanglement of the cloth while maintaining the required cleaning power. The detergent concentration of the high-concentration detergent liquid that sinks into and sinks into the laundry is 5 to 30 times the detergent concentration in the wash water. Considering variations in detergent liquid generation and supply, set the target value at about 10 times. It is convenient to do this.

Next, water is supplied up to the amount of water (water level) set to a preferable value for washing. In this water supply process, the stirring blade is driven to rotate to detect the amount of laundry (cloth amount sensing and fabric quality sensing), and the laundry quality is estimated based on the results of the fabric amount sensing and fabric quality sensing, The on / off time limit of the inversion drive, the washing time, and the set water level are corrected. The on-time limit of the inversion drive is set so that it becomes longer as the amount of laundry increases.

When the water supply up to the set water level is completed, the stirring impeller and the washing / dehydrating tub are reversely driven to perform washing and stirring control for exerting a mechanical force on the laundry. This washing agitation control operates the switching clutch mechanism in the first or second drive mode according to the amount of laundry, and also has the on / off time limit and the washing time of the reversal drive set according to the amount and quality of the laundry. Run according to. When the amount of laundry is less than a predetermined amount (80% of the rated load amount in this embodiment), the switching clutch mechanism is set to the second driving mode to rotate the stirring blade and the washing / dehydrating tub in opposite directions. Washing and stirring is performed by reversal drive that gives a driving force, and when the amount is not less than a predetermined amount, first, the switching clutch mechanism is set to the second drive mode and reversal drive that gives a rotational driving force in the opposite direction to the stirring blade and the washing / dehydrating tub Washing and stirring is performed, and then, the switching clutch mechanism is set to the first drive mode and the washing and stirring tank is reversed and the washing and stirring is performed. In washing and stirring with a predetermined amount or more, the ON time limit of the first drive mode is set shorter than the ON time period of the second drive mode to prevent an excessive stirring force.

Here, the reversal drive means repetition of forward rotation drive of the stirring blade → pause → reverse rotation drive → pause → forward rotation drive, which is an ON-timed forward or reverse rotation drive. Of one time (power-on time to the drive motor), and the off-time means rest time.

In such a washing process, the chemical detergency of the high-concentration detergent liquid is effectively utilized, so that it is possible to sufficiently remove the dirt with a small stirring force (mechanical force), and the entanglement and Reduces fabric damage.

When the washing is completed, the washing water is drained, and the switching clutch mechanism is operated in the third drive mode to integrally rotate the stirring blade and the washing / dehydrating tub in one direction at a high speed to include the washing in the laundry. Centrifuge the existing wash water.

Next, water is supplied up to the amount of water (water level) set to a preferable value for rinsing, and reverse driving for rinsing and stirring is executed. As the reversal drive for the rinse agitation, the reversal drive according to the second drive mode is adopted when the amount of laundry is less than a predetermined value, and the reversal drive according to the first drive mode is adopted when the amount of laundry is greater than the predetermined value.

Upon completion of the set rinsing and stirring, the rinsing water is drained, and the switching clutch mechanism is operated in the third driving mode to integrally rotate the stirring blade and the washing / dehydrating tank in one direction at a high speed. Centrifuge the rinse water contained in the laundry.

This rinsing and stirring, drainage and centrifugal dewatering are repeated as many times as necessary, and the final dewatering is carried out until a dewatering state suitable for the subsequent cloth loosening finishing process and drying process is achieved.

When the final dehydration is completed, the laundry is
It is in a state of being pressed against the side wall of the washing and dehydrating tub and stuck. In order to make it easier to take out such laundry, a cloth loosening finishing step is executed. In the cloth loosening finishing process, the on / off time limit of the reversing drive and the stirring time are set according to the amount of laundry (detection result of detergent amount sensing), and stirring is performed to peel off the laundry stuck to the washing / dehydrating tub. Driving, stirring drive to loosen the washed laundry is executed. As mentioned above, the washing performed by reducing the mechanical force by effectively utilizing the chemical washing power of the high-concentration detergent solution reduces the entanglement of the laundry, so the washing process can be easily performed by the cloth loosening finishing process. It is possible to loosen the cloth.

Also, when washing with cold water such as in the winter, or when it is desired to warm the laundry, by pressing a predetermined key, the blower means and the heating means are operated from the start of the final dehydration to wash and dehydrate. After the air in the tub is sucked out and then heated and blown into the washing / dehydrating tub, the circulating air is brought into contact with the laundry to warm it, and after the completion of the dehydration, a cloth loosening finishing process is executed.

When the dehydrated laundry is dried in the washing / dehydrating tub, after the washing / dehydrating tub is slowly rotated, the air blowing means and the heating means are operated to suck out the air in the washing / dehydrating tub to dehumidify it. By heating and blowing it into the washing / dehydrating tank, the laundry is exposed to the circulating air and dried. As described above, the washing performed by reducing the mechanical force by effectively utilizing the chemical cleaning power of the high-concentration detergent liquid reduces the entanglement of the laundry, so that the circulating air is evenly distributed over the laundry. It is effective in touching and increasing the drying efficiency.

FIG. 8 is a flow chart of each operation control executed by the microcomputer 16a in the control unit 16.

When the power switch 13 is turned on, the microcomputer 16a executes the following control processing.

Step 801 When the power is turned on, the initialization processing of the control processing system is performed, and then the clutch mechanism initialization control processing for driving the clutch operating motor 62a so that the switching clutch mechanism 62 is in the second drive mode. I do.

This clutch mechanism initialization control processing is shown in FIG.
As shown in the flowchart of FIG.
a is activated (step 801a). Then, by observing the position detection signals from the two position detection switches 62w to confirm that the operating electric motor 62a has reached the position corresponding to the first or third drive mode (step 801b), any position detection is performed. When the signal is confirmed, the time required to move from there to the intermediate position (second drive form) is set. Since this required time is affected by the state of the cam drive section, the required time from the first drive mode to the intermediate position and the required time from the third drive mode to the intermediate position are set individually ( Step 801c). After that, the operating electric motor 62a is operated and stopped until the set required time elapses (steps 801d and 801e). The stop position of the operating electric motor 62a corresponds to the cam rotation position where the switching clutch mechanism 62 is in the second drive mode.

Step 802 Put the laundry clothes 38 into the washing / dehydrating tub 2 and operate the operation panel 1
4 input switch group 14a is operated to perform initial setting,
When the start button switch is pressed, the automatic control process for each operation is started.

In the initial setting, the course and mode are selected and set. Here, the operation control when the washing / drying course is set is illustrated.

Step 803 The detection control process of the laundry amount of the laundry 38 is performed. The amount of cloth is detected by maintaining the switching clutch mechanism 62 of the drive device 6 in the second drive mode in a dry cloth state before water supply.
The drive motor 61 is energized for a short period of time to rotationally drive the stirring blade 4, and detection is performed based on the reached rotational speed at that time. This rotation speed is detected based on the detection signal of the rotation sensor 61b. Based on the detection result of the laundry amount, the wash water amount and the detergent amount for producing wash water having a preferable detergent concentration are calculated and determined, and the detergent amount is displayed.
A corresponding amount of the powdered synthetic detergent indicated by is put into the detergent dissolving container 21.

Step 804 The switching clutch mechanism 62 of the drive unit 6 is maintained in the second drive form or controlled in the third drive form, and the drive motor 61 is operated at a low speed to wash and dewater the tub 2 and the stirring blades 4. While rotating at a low speed, the main water supply solenoid valve 20 is opened to supply tap water directly to the water inlet 19, and the tap water is sprayed onto the laundry 38 in the washing / dehydrating tank 2. The laundry 38 absorbs the tap water that has been sprayed and becomes wet, so that the bulk is reduced. The amount of tap water sprayed at this time is controlled according to the amount of laundry 38 detected by the detection operation, and is controlled to be small when the amount of laundry 38 is small and to increase as the amount of laundry 38 increases. This water supply amount is controlled by the opening time of the main water supply solenoid valve 20.

Step 805: The auxiliary water supply solenoid valve 22 is opened to supply a small amount of tap water (detergent-dissolved water) to the detergent-dissolving container 21 so that the detergent-dissolving container 21 does not overflow. A high-concentration detergent liquid is generated by dissolving the powder synthetic detergent in the container 21 with the detergent-dissolving water while operating the detergent agitating motor 39 to agitate. The amount of the detergent-dissolved water is set to an amount suitable for sufficiently dissolving the powder synthetic detergent while stirring without overflowing from the overflow portion of the detergent-dissolving container 21.

Step 806 The switching clutch mechanism 62 of the drive unit 6 is maintained in the second drive form or controlled in the third drive form, and the drive motor 61 is operated at a low speed to wash and dewater the tub 2 and the stirring blades 4. While rotating at a low speed, the auxiliary water supply solenoid valve 22 is opened to dilute and supply the detergent dissolving container 21 to dilute the high-concentration detergent liquid to overflow from the overflow portion, thereby sending the water to the water injection port 19 and the main water supply solenoid valve. 20 is opened and water is supplied to the water injection port 19 to dilute the high-concentration detergent liquid to a preferable high-concentration detergent liquid (detergent concentration of 5 to 30 times the detergent concentration of the wash water), and the laundry 38 in the washing / dehydrating tank 2 And then submerge it in the laundry 38.

The high-concentration detergent liquid submerged in the laundry 38 exerts its chemical high cleaning power on the laundry 38 to enhance the cleaning power, so that the mechanical force acting on the laundry 38 in the washing operation is increased. It is possible to reduce the damage and the entanglement of the cloth.

In the wash water produced by dissolving the powder synthetic detergent in a large amount of tap water, the amount of zeolite contained in the detergent is insufficient and the effective surfactant is greatly reduced.
However, since the high-concentration detergent liquid produced by dissolving the powder synthetic detergent with a small amount of tap water (detergent-dissolved water) (for example, detergent concentration 10 times the detergent concentration of washing water) has a small amount of metal ions. , The zeolite functions sufficiently and the reduction of the effective surfactant can be suppressed to an extremely small amount (about 2%). Therefore, when such a high-concentration detergent liquid is dropped on and immersed in the laundry, the detergent liquid permeates into the laundry (dirty clothes) at a high speed (about four times the speed of the wash water) and quickly becomes dirty. The surface active agent promotes emulsification and dispersion of dirt, the alkaline material promotes swelling and saponification of oil dirt, and the enzyme exerts detergency to decompose dirt of fat and protein.

Step 807 This is a time for promoting the penetration and immersion of the high-concentration detergent liquid that has fallen on the laundry 38 into the laundry 38, and may be omitted.

Step 808: The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened to start the supply of tap water (wash water). This wash water is supplied up to the amount of water determined in step 803,
During the water supply, the process is interrupted to detect the amount of cloth (a compress value) and the quality of the laundry 38. This interrupted water level is a water level that is preset in the microcomputer 16a and is suitable for detecting the amount of compress and detecting (estimating) the cloth quality.

Step 809 The amount of wet cloth and the quality of cloth are detected to correct the amount of water supplied for washing, and the control constants in washing, rinsing, dehydration, drying and cloth loosening finishing operations are determined. In order to detect the amount of compress, the water supply is interrupted at a predetermined low water level to control the switching clutch mechanism 62 of the drive device 6 in the second drive mode, and the drive motor 61 is urged for a short time to rotationally drive the stirring blade 4. Then, the first compress amount is detected based on the reached rotation speed at that time (this rotation speed is detected based on the detection signal of the rotation sensor 61b), and then,
Based on the reached rotation speed when the water supply is restarted and the wash water is replenished to a predetermined high water level, and then the water supply is interrupted to energize the drive motor 61 of the drive device 6 for a short time to rotationally drive the stirring blade 4. It is executed so as to detect the second compress amount. Then, the cloth quality of the laundry 38 is detected (estimated) based on the difference between the first compress amount and the second compress amount. This cloth quality detection control is omitted when it becomes unnecessary due to the initial setting.
Then, depending on the amount of cloth and the quality of the cloth, the water flow in the washing and rinsing operations (mechanical agitation strength = on-off time limit) and the operating time and the control constants in the drying operation are determined.

Step 810 Supply tap water up to the amount of water determined in step 803.
By this water supply, the wash water is further diluted with the high-concentration detergent liquid to have a detergent concentration suitable for stirring and washing. As a result, the laundry 38 is immersed in washing water having a predetermined detergent concentration in the washing / dehydrating tub 2, and the washing / dehydrating tub 2 and the stirring blades 4 are rotated so that the laundry 38 has a mechanical washing power. The state becomes suitable for applying (stirring).

Step 811 The drive unit 6 is controlled so as to perform the washing process with the washing water flow and washing time set in Step 809. In this washing process, the drive device 6 changes the drive mode of the switching clutch mechanism 62 according to the amount of the laundry 38 and the stirring blade 4 is changed.
Is reversed (washing and stirring).

Specifically, as shown in the flowchart of FIG. 10, the laundry amount of laundry 38 is set to a predetermined value (in this embodiment, the rated load amount is 8 kg and 80% thereof is set to a predetermined value). The drive device 6 is compared depending on the comparison.
The control is branched so as to change the driving mode of the (switching clutch mechanism 62) (step 811a).

When the amount of laundry 38 is less than the predetermined value,
The operation electric motor 62a is controlled so that the switching clutch mechanism 62 of the drive device 6 is set to the second drive mode (step 811b). Then, the drive motor 61 is operated so as to reversely drive the stirring blade 4 (step 811c). In this state, the rotational driving force of the drive motor 61 is equal to the speed reduction mechanism 63.
Is transmitted to the stirring blade 4 after being decelerated via the deceleration mechanism 6
The reaction force acting on the internal gear 63j of the planetary gear mechanism at 3 gives the washing / dehydrating tank 2 a rotational driving force in the opposite direction to the stirring blade 4. Therefore, by repeating the forward / reverse operation of the drive motor 6, the washing / dehydrating tub 2 and the stirring blade 4 are repeatedly rotated in opposite directions, and a mechanical washing force is exerted on the laundry 38. The mechanical (stirring) force applied to the laundry 38 is adjusted by adjusting the on / off time limit in the forward / reverse operation of the drive motor 61 for reversely driving the washing / dehydrating tub 2 and the stirring blades 4 and adjusting the rotation speed. Alternatively, it can be controlled by adjusting the washing (stirring) time. For example, the on-off time is set to 0.6 to 1.9 seconds and the off time is set to 0.4 to 0.7 seconds according to the amount of the laundry 38.

When the amount of laundry 38 is greater than or equal to a predetermined value,
Reversing drive in which the switching clutch mechanism 62 is in the second drive mode (first half) and inversion drive in which it is the first drive mode (second half).
To execute. First, the operation electric motor 62a is controlled so that the switching clutch mechanism 62 of the drive device 6 is set to the second drive mode (step 811d). Then, the drive motor 61 is operated in the forward and reverse directions so as to drive the stirring blade 4 in the reverse direction (step 811e). In this state, as described above, the stirring is performed by the inversion drive that applies the inversion drive force in the opposite direction to the stirring blade 4 and the washing / dehydrating tub 2. After that, the operation electric motor 62a is controlled so that the switching clutch mechanism 62 of the driving device 6 is set to the first driving mode (step 811).
f). Then, the drive motor 61 is operated in the forward and reverse directions so as to drive the stirring blade 4 in the reverse direction (step 811g). This first
In the drive mode of No. 3, the switching clutch mechanism 62 has the engagement projection 62k of the slider 62d engages with the locking projection 62j of the steel plate base 62c to lock the outer input shaft portion 63h, and the internal gear of the speed reduction mechanism 63. By locking 63j, a static force is applied to the washing / dehydrating tub 2, and the drive motor 6
The rotational force of 1 is transmitted to the stirring blade 4 via the speed reduction mechanism 63 and the central output shaft 64, and the stirring blade 4 is rotated to perform the inversion drive. The on-off time limit is set, for example, to 2.0 seconds (on) -0.5 seconds (off) in the reverse driving in the second driving mode in the first half, and in the reverse driving in the first driving mode in the second half, for example. , 1.5 seconds (on) -0.7 seconds (off).

Since this fully automatic washer / dryer utilizes the high chemical washing power of the high-concentration detergent liquid, even a small mechanical (agitation) force can be applied to the laundry 3 compared to the conventional washing method.
Since the stains of 8 will come off well, the laundry 38
It is possible to reduce the damage and the entanglement.

Step 812: The drainage solenoid valve 33 is opened to drain the wash water out of the machine. In this drainage operation, after the drainage is completed or at the end of the drainage, the switching clutch mechanism 62 is operated in the second drive mode to integrally rotate the stirring blade 4 and the washing / dehydrating tub 2 in one direction at a high speed to wash the laundry 38. The drive device 6 is controlled so as to centrifugally dehydrate the wash water contained in the. In this centrifugal dehydration,
When the outer tub 5 is largely shaken by the deviation of the laundry 38 and the unbalance detection sensor 43 operates, the high-speed rotation drive is interrupted and the uniform operation control of the laundry 38 is executed.

Step 813 The main water supply solenoid valve 20 and the auxiliary water supply solenoid valve 22 are opened to supply rinsing water (tap water) up to the set water amount. If necessary, the auxiliary water supply solenoid valve 22a is opened to mix the finishing agent.

Step 814 The drive unit 6 is controlled to execute the rinsing operation. In this rinsing operation, the drive mode of the switching clutch mechanism 62 is changed according to the amount of the laundry 38 to reversely drive the stirring blade 4 (rinse stirring drive).

Specifically, as shown in the flow chart of FIG. 11, the laundry amount of the laundry 38 is compared with a predetermined value (80% of the rated load amount in this embodiment), and the switching clutch is changed depending on the amount. The control is branched so as to change the driving mode of the mechanism 62 (step 814a).

When the amount of laundry 38 is less than the predetermined value,
The operation electric motor 62a is controlled so that the switching clutch mechanism 62 of the drive device 6 is set to the second drive mode (step 814b). Then, the drive motor 61 is operated so as to reversely drive the stirring blade 4 (step 814c). In this state, the rotational drive force of the drive motor 61 is decelerated and transmitted to the stirring blade 4 via the planetary gear reduction mechanism 63, but the reaction force acting on the internal gear 63j in the planetary gear reduction mechanism 63 causes washing and washing. A rotation driving force in the opposite direction to the stirring blade 4 is applied to the dehydration tank 2. Therefore, by repeating the forward / reverse operation of the drive motor 6, the washing / dehydrating tub 2 and the agitating blade 4 are repeatedly rotated in opposite directions, and a mechanical rinsing force is applied to the laundry 38. The mechanical (rinse agitation) force applied to the laundry 38 is used to adjust the on-time in the forward / reverse operation of the drive motor 61 for inverting and driving the washing / dehydrating tub 2 and the stirring blades 4,
It can be controlled by adjusting the number of rotations or adjusting the rinsing (stirring) time. The on-off time is, for example, according to the amount of laundry 38, and the on-time is
It is set to 0.4 to 1.6 seconds, and the off time is set to 0.4 to 0.7 seconds.

When the amount of laundry 38 is greater than or equal to a predetermined value,
Inversion drive (rinse agitation drive) in which the switching clutch mechanism 62 is in the first drive mode is executed. First, the operation electric motor 62a is controlled so that the switching clutch mechanism 62 of the drive device 6 is set to the first drive mode (step 814d).
Then, the drive motor 61 is driven so as to reversely drive the stirring blade 4.
Is operated in the reverse direction (step 814e). In the first drive mode, the switching clutch mechanism 62 includes the slider 62d.
Of the engaging projection 62k is a locking projection 62j of the steel plate base 62c.
To lock the outer input shaft portion 63h,
By washing the internal gear 63j of the washing and dewatering tank 2
A static force is applied to the drive motor 61, and the rotational force of the drive motor 61 passes through the reduction mechanism 63 and the central output shaft 64.
Is transmitted to the rotor to rotate the stirring blade 4 to execute the inversion drive. The on-off time period is set to, for example, 1.5 seconds (on) -0.7 seconds (off).

Step 815 The drainage solenoid valve 33 is opened to drain the rinse water out of the machine. Then, after the drainage is completed or in the final stage, the switching clutch mechanism 6
2 is operated in a second drive mode to integrally rotate the stirring blade 4 and the washing / dehydrating tub 2 in one direction at a high speed to centrifugally dewater the wash water contained in the laundry 38. Control 6 Even in this centrifugal dehydration, the laundry 3
When the outer tub 5 is largely shaken by the deviation of 8 and the unbalance detection sensor 43 operates, the high-speed rotation drive is interrupted and the laundry 38 is leveled.

Water supply, stirring, drainage, and centrifugal dehydration in this rinsing are repeated a plurality of times as necessary. Centrifugal dehydration in the final rinse is the next dehydration operation.

Step 816 The switching clutch mechanism 62 of the drive unit 6 is controlled in the third drive mode while the drainage electromagnetic valve 33 is kept open, and the drive motor 61 is operated at high speed to wash and dewater the tub 2 and the stirring blades. By rotating 4 integrally at a high speed, the water contained in the laundry 38 is centrifugally dehydrated. Also in this centrifugal dehydration, when the outer tub 5 is largely shaken due to the deviation of the laundry 38 and the unbalance detection sensor 43 operates, the high-speed rotation drive is interrupted and the uniform operation control of the laundry 38 is executed. With this final dehydration process completed,
The laundry 38 is pressed against the side wall of the washing / dehydrating tub 2 and stuck to the side wall surface.

Step 817 The switching clutch mechanism 62 of the drive unit 6 is controlled to the first drive mode, and the drive motor 61 is operated in the reverse direction so as to drive the stirring blade 4 in the reverse direction. The laundry 38 that is pressed against the side wall of the aquarium 2 and stuck to it is peeled off. Then, while stirring the laundry 38 by the stirring ribs 4b of the stirring blade 4 so as to hook it, the cloth is unraveled so that it can be easily taken out.

At this time, the on / off time limit in the normal / reverse operation, the number of revolutions, and the number of times of the forward / reverse operation differ depending on the amount of the laundry 38. When the amount of the laundry 38 is small, the number of revolutions and the number of the forward / reverse operations. Can be reduced. The on-off time is, for example, 0.4 to 1.5 depending on the amount of laundry 38.
Second, off time is set to 0.4 to 3.0 seconds. Further, the cloth can be efficiently unraveled by combining several patterns of on-off time periods.

In the on-off time period of several patterns,
It is also possible to rotate the stirring blade 4 only in one direction in a state of being controlled in the first drive mode, and perform a normal rotation drive in which the laundry 38 attached to the side wall of the washing / dehydrating tub 2 is pulled and pulled off. It is possible.

At the start of the final centrifugal dehydration (step 81
By controlling the circulation fan 26 and the heater 29 from 6) to generate circulation air blown in the direction opposite to the rotation direction of the washing / dehydrating tub 2, the laundry 38 is warmed to wash with cold water such as in cold winter. Even in such a case, the laundry 38 after the cloth loosening finishing process is warmed can be taken out easily. Further, at this time, since the laundry 38 is stirred while being heated with warm air, the fibers of the laundry 38 are stretched to reduce wrinkles due to dehydration and can be finished softly. By adjusting the time of adding the hot air at this time, it is possible to sterilize the bacteria adhering to the laundry 38 and to suppress the mold generated in the washing / dehydrating tub 2.

Step 818 With the switching clutch mechanism 62 of the drive unit 6 maintained in the third drive mode, the drive motor 61 is operated to operate the circulation fan 26 while rotating the washing / dehydrating tub 2 and the stirring blade 4. Then, the air in the outer tub 5 is sucked out from the suction port 5a, and when passing through the water cooling / dehumidifying duct 23, it is cooled and dehumidified by the cooling water supplied from the cooling sprinkler 24 into the water cooling / dehumidifying duct 23, and the downflow duct is formed. 25 is sucked into the circulation fan 26, is sent from the circulation fan 26 to the blowout port 30 through the ascending air duct 27 and the heater 29, is heated by the heater 29, and is washed toward the vicinity of the inner wall surface in the washing / dehydrating tub 2. Circulating air blown in the direction opposite to the rotation direction of the dehydration tub 2 is generated to dry the laundry in the washing / dehydration tub 2.

In the warm air drying operation, basically, according to a predetermined time schedule set in advance, the circulation fan 26 is operated while rotating the washing / dehydrating tub 2 and the stirring blade 4, and the washing / dehydrating tub 2 is operated. Air in the (outer tank 5) is ducted 2
3, 25 and 27 are circulated, and water is cooled and dehumidified by spraying water from the cooling water sprinkling unit 24, and the circulating air that has been water-cooled and dehumidified is heated by the heater 29.
The set mode, the amount of laundry 38, the humidity of the circulating air (the detection signal of the humidity sensor 40) and the temperature (the temperature sensor 4
1, 42) and unbalance (detection signal of unbalance detection sensor 43) detection results, rotation control of washing / dehydrating tub 2 and stirring blade 4, operation control of circulation fan 26, and heat generation of heater 29. Control and sprinkling control of the cooling sprinkling unit 24 are executed.

Such a fully automatic washer / dryer can be implemented as a fully automatic washer / dryer that executes washing to dehydration by omitting the warm air circulation drying means and its control processing.
