2. Description of the Related Art In general, a drum-type washing and drying machine has a structure in which a drum rotates around a horizontal axis in a water tank, and since washing and drying can be performed by the same drum, washing, rinsing, dehydrating, and drying are performed. It is a typical washing and drying machine that performs each process.

FIG. 9 shows the overall configuration of a conventional drum type washing and drying machine. In FIG. 9, 1 is a washing machine main body, 2 is an aquarium,
Reference numeral 3 denotes a spring for suspending the water tank 2, 4 denotes a drum for storing laundry, 5 denotes a number of small holes formed on the peripheral wall of the drum 4, 6 denotes an inflow path, 7 denotes an outflow path, and 8 denotes drying. Heater, 9 a blower, 10 a water supply valve, 11 a water level sensor, 1
2 is a drive motor, 13 is a drive transmission mechanism for transmitting the driving force of the drive motor 12 to the drum 4, 14 is a drain pump, 15
Is a washing water heating heater, 16 is an opening / closing door, and 17 is a sealing gasket.

Although not shown, a lock function for holding the opening / closing door 16 in a closed state, a cloth amount detecting function for detecting a cloth amount of the laundry in the drum, and a notification function for notifying the end of the operation by a notification buzzer after the operation is completed are provided. Added washer / dryer body 1
Is provided with a stop key for temporarily stopping each step of water supply, washing, rinsing, dehydrating, and drying.

[0005] In the washing process, laundry is put into the drum 4, and washing water in which a detergent is dissolved is poured into the drum 4 from above to be included in the laundry, and the drum 4 is rotated at a low speed. The laundry in the drum 4 is lifted to near the top of the drum 4 by centrifugal force due to the rotation of the drum 4 and a baffle (not shown), and then falls by its own weight (tumbling).
I do. By repeating this tumbling, the laundry is washed by the impact force at the time of falling. Rinsing is also performed by repeating tumbling.

The amount of washing water in the water tub 2 during the washing process is about 5 to 10 liters, and the level of the washing water is about halfway between the center and the lower end of the door 16. For this reason, when the pause key is pressed for taking in and out the laundry during the washing and rinsing process, most of the washing water in the water tub 2 is drained so that washing water (including rinsing water) does not spill outside the machine. After that, the door 16 is unlocked. In addition,
Generally, the amount of water used in the final stage of the washing process or the rinsing process is larger than that in the washing process.

In the dewatering process, the drum 4 is rotated at a high speed, and the laundry in the drum 4 is pressed against the inner surface of the peripheral wall of the drum 4 by using the centrifugal force. At this time, the water contained in the laundry is blown from the small holes 5 of the drum 4 toward the water tub 2, guided to the lower part along the inner surface of the water tub 2, and discharged out of the machine by the drainage pump 14.

In the drying step, the drum 4 is rotated at a low speed while blowing the hot air heated by the drying heater 8 into the drum 4 through the inflow path 6 by the blower 9. The hot air blown into the water tank 2
The temperature of the entire inside of the water tub 2 including the laundry is increased by evaporating the water contained in the laundry.

The high-temperature and high-humidity air is cooled by coming into direct contact with cooling water while reaching the drying heater 8 through the outflow path 7. As a result, moisture in the air is condensed, and the moisture is discharged out of the device to perform dehumidification. The dehumidified air is heated again by the drying heater 8 and blown into the drum 4. The laundry is dried by repeating this cycle.

[0010]

In the conventional front-loading type drum type washer / dryer, since it is notified that the operation has been completed, it is necessary to confirm the completion of the operation and then perform the operation for unlocking the opening / closing door 16 or the like. Time is required until the lock is automatically released, and the laundry cannot be taken out immediately after the operation is completed, resulting in poor efficiency.

Also, when the laundry is taken in and out after the water supply, washing, and rinsing steps are temporarily stopped, since most of the washing water in the water tub 2 is drained, it takes time until the opening and closing door 16 can be opened. Since the opening / closing door 16 cannot be opened immediately after the operation of the temporary stop, the efficiency is low. Further, when the washing and rinsing process is continued, it is necessary to replenish the washing water again, and the washing water is wasted.

Further, when additional laundry is loaded during the operation, there is no function to display the amount of laundry that can be added to the drum 4, so that the amount of laundry determined visually from outside is loaded. Was. In this case, since the diameter of the opening / closing door 16 is smaller than the diameter of the drum 4, it is difficult to confirm the inside of the drum 4, and the amount of washable cloth and the amount of dryable cloth are different. It is difficult to determine the amount of cloth that can be added.

For this reason, various improvements have been proposed in consideration of the above problems. However, these problems are insufficient to solve these problems, and sufficient effects cannot be expected by themselves.

Is what you do. However, the determination of the presence / absence of the suspend key is limited to the time when the process is shifted, and sufficient consideration is not given to the relationship with a safety device such as a door lock.

JP-A-2-131798 and JP-A-2-164396 disclose that an auxiliary water tub is provided to improve reuse of the washing liquid and transfer of the washing liquid from the water tank to the auxiliary water tank only (the air of the transfer pump is not provided). (Including prevention of bruising). However, it does not relate to improvement of operability at the time of suspension, improvement of safety, and the like.

Japanese Unexamined Patent Publication No. 2-241493 discloses a method of detecting the amount of laundry before water is supplied, and if the detected amount of laundry is less than the amount of dryable laundry, the laundry is dried. This is set automatically for the course. But,
There is still room for improvement in usability in respect of the user's will, additional loading of laundry during a pause, and the like.

In view of the above, the present invention can improve the safety and work efficiency by improving a series of operations such as notification at the end of operation or when each process is temporarily stopped, drainage and transfer of washing water in a water tub, and the like.

When the selected driving course is started, the amount of laundry put into the drum 25 is detected and determined, and the result is stored. When there is no washing water in the water tub 23 from the time the start key is pressed to the start of water supply, the drive motor 32 rotates the drum 25 into which the laundry has been loaded, and the drive motor 32 Is determined based on the time required until the rotation speed at the time of rising reaches a predetermined rotation speed.

As shown in FIG. 7, the time required for the drive motor 32 to reach a predetermined number of revolutions when the drive motor 32 rises becomes longer as the amount of laundry put in increases. Further, the cloth amount can be determined in a short time from the value obtained by calculating the slope of the rising curve of the rotation speed of the drive motor 32.

Here, when the washing course is selected, the information buzzer and the display panel 40 notify that the amount of clothes in the drum 25 exceeds the maximum amount of washing. Also, when the washing / drying course is selected, the same notification is made even if the maximum amount of dried cloth is exceeded. In a drum-type washing / drying machine, the maximum amount of dry laundry is generally about half of the maximum amount of laundry.

When the water supply into the water tank 23 starts, water is supplied until the water level sensor 33 detects a predetermined water level corresponding to the cloth amount. When the pause key is pressed after the start of water supply, the water supply is stopped. If the water level in the water tank 23 is equal to or lower than the set water level, the lock pin 53 in the lock mechanism 42 retreats and comes off from the engagement hole 51 a of the lock lever 51. Then, the lock of the opening / closing door 41 is released, and a notification that the opening / closing door 41 can be opened is notified by a notification buzzer.

When additional laundry is to be added, the opening / closing door 41 is opened and the laundry within the displayed amount of laundry is inserted.

When the water level in the water tub 2 exceeds the set water level, the on-off valve 74 is opened and the drain valve 73 is closed to drive the drain pump 30, and the washing water drained from the water tank 23 is supplied to the auxiliary tank 31. Transfer to At this time, the auxiliary tank 3
The air in 1 is discharged to the outside from the air release valve 75, and the drained washing water is smoothly transferred into the auxiliary tank 31.

Further, while the washing water in the water tub 23 is being drained, a display lamp indicating a water supply process on the display panel 40 is flickered and a notification buzzer is notified. At this time, the generation cycle of the buzzer sound of the notification buzzer is longer than when the door 41 is unlocked or when the cloth amount is abnormal (for example, 0.2 seconds on,
1.5 seconds off) to distinguish it from other announcements.

Thereafter, when the water level in the water tank 23 drops to the set water level, the on-off valve 74 is closed, the door 41 is unlocked and the buzzer informs, and the blinking display lamp is turned on. Then, the surplus washing cloth amount or the surplus drying cloth amount is displayed on the display panel 40 according to the selected driving course. When additional laundry is to be added, the opening / closing door 41 is opened and the laundry within the displayed amount of laundry is inserted.

When the start key is pressed again, the door 41 is opened.
When there is washing water in the auxiliary tank 31, the on-off valve 74 is opened and the washing water is automatically dropped, and the water tank 2
3 and water is supplied until the water level in the water tank 23 reaches a predetermined water level. When the water supply is completed, the washing process is started.

When the pause key is pressed during the washing process, if the progress of the process is 90% or more, the operation is stopped, the on-off valve 74 is closed, the drain valve 73 is opened, and the drain pump 30 is opened. To drain all the washing water in the water tub 23 out of the machine. During draining, a display lamp indicating the washing process of the display panel 40 is flickered, and the intermittent buzzer sounds. Then, the lock of the opening / closing door 41 is released, and a notification is given by a notification buzzer.

On the other hand, when the progress of the washing process is less than 90%, the washing water drained from the water tank 23 is transferred to the auxiliary tank 31 as described above, the display lamp blinks, and the intermittent buzzer sounds. To inform. And the opening and closing door 41
Is unlocked, the buzzer informs and the display panel 4
A value of 0 indicates a surplus washing cloth amount or a surplus drying cloth amount.

When the start key is pressed again, the washing process is completed when all the washing water is drained out of the machine, and when the washing water is present in the auxiliary tank 31, the washing process is returned to the water tub 23 and the washing process is performed. continue.

When the washing process is completed, intermediate dehydration is performed, and the detergent liquid contained in the laundry is discharged. Then, the water supply process is performed again and the rinsing process is started. When the pause key is pressed during the water supply process, the process is performed in the same manner as the water supply process before the washing process. However, in this water supply step, since the washing step has already been completed, there is no need to additionally load the laundry, and the display of the extra cloth amount is not performed.

Thereafter, each step of rinsing and dehydration in the washing course and each step of drying in the washing and drying course are performed. After the operation is completed, the lock of the opening / closing door 41 is released, and the operation is terminated by the notification buzzer. Notify that.
In addition. The operation in each step is the same as in the related art, and will not be described.

As described above, since the notification is made after the unlocking of the opening / closing door 41 after the operation is completed and when each process is temporarily stopped, the opening / closing door 41 can be opened immediately after the notification and the laundry can be taken in and out. . Thus, the inconvenience of waiting until the lock of the opening / closing door 41 is released after the notification as in the related art can be eliminated.

In order to flash the indicator lamp of the process in the paused state, and to change the cycle of the buzzer sound generated by the notification buzzer in accordance with various situations such as during drainage, after unlocking of the opening / closing door 41, etc. It is easy to grasp the situation.

When each washing process is temporarily stopped, the water tank 23
When the washing water in the inside is equal to or higher than the set water level, the washing water is drained to the set water level and the door 41 is unlocked. For this reason, it is possible to make the opening / closing door 41 openable in the shortest possible time by minimizing the amount of washing water to be drained, and it is possible to efficiently add laundry, etc., and to save washing water.

When the washing or rinsing process is temporarily stopped and the process is almost completed, the washing water in the water tub 23 is drained, and the process is completed. Therefore, when the operation is started again, the next step can be immediately started, and the washing time can be reduced and the washing water can be saved as compared with the case where the water is supplied again and the remaining few steps are performed.
