In addition, a timer 80 that counts the time displayed on the liquid crystal panel 75, a motor 15 that rotates the drum 30, a compressor 53, a drain valve 18, a water supply device 49b, and a fan motor 49b are also connected.

Next, the operation of the above configuration will be described.
First, as the known washing and drying function, as is well known, washing, rinsing, dehydration, and a drying process are executed.
Then, each stroke is selected and executed by the operation key of the operation panel 3.
For example, when the washing, rinsing, dehydration, and drying processes are automatically performed and the "standard" course is desired, first, the door 5 is opened and the laundry (not shown) is passed through the laundry inlet 4. Then, it is put into the drum 30 from the laundry entrance 33 and stored. Then, the detergent is accommodated in the detergent case 21, the on button 61 of the power operation unit is pressed, and the drum type washing and drying machine is turned on.
Then, the washing / drying key 63b for automatically performing the operation from “washing” to “drying” in the selection operation unit 63 is selected and pressed.
Then, “Standard” on the course display section 66 is lit, and the dial 72 is rotated,
The characters to be lit on the course display section 66 are sequentially changed to “standard”, “speedy”, and “careful”.
Then, when “Standard” on the course display section 66 is lit, the push button 73 is pressed to select and set the operation from “washing” to “drying” in the “standard” course operation. It operates based on the stored various driving course programs.
The operation of the “standard” course will be described automatically from “washing” to “drying”.

First, in the washing process, first, the drain valve 18 is closed, and water is supplied from the water supply device 22 through the detergent case 21 and the flexible hose 20 into the water tank 6 and stored. At this time, detergent case 21
The detergent accommodated in the tank is also supplied into the water tank 6 together with water. The motor 15 is driven and the drum 30 is rotated in both forward and reverse directions at a low speed, whereby the laundry in the drum 30 is washed. At this time, the baffle 32 sequentially draws up the laundry and the washing water to promote the stirring of the washing and the washing water.
When the washing process is completed, the drain valve 18 is opened and the water in the water tank 6 is discharged, followed by intermediate dehydration. The intermediate dehydration is performed by causing the motor 15 to rotate the drum 30 in one direction at a high speed to discharge water contained in the laundry from the holes 31 by centrifugal force. When the intermediate dehydration is completed, a rinsing process is performed. The rinsing process is performed in the same manner as the washing process except that no detergent is used when supplying water. When the rinsing process is completed, a final dehydration process is performed. The final dehydration process is similar to the intermediate dehydration process.
Is performed by rotating the drum 30 at a high speed in one direction.

When this final dehydration process is completed, a drying process is performed next. In the drying process, the motor 15 rotates the drum 30 in both forward and reverse directions at a low speed, and drives the blower 49 and the compressor 53 of the heat pump mechanism 50. Among these, when the blower 49 is driven, the drying unit duct 4 is caused by the blowing action of the fan 49a as shown by the solid arrow A in FIG.
3 is sucked to the fan casing 44 side and discharged from the discharge port 45 to the air supply duct 47 side through the flexible duct 46.
The air discharged to the air supply duct 47 is supplied from the air supply port 16 into the water tank 6. Most of the air supplied into the water tank 6 is supplied into the drum 30 through the holes 31 of the drum 30.
The air in the drum 30 and the water tank 6 flows toward the opening of the water tank 6, hits the rear glass 98 and the bellows 8 of the door 5, and is discharged from the exhaust port 40 at the front part of the water tank 6 to the exhaust duct 41 side. . The air discharged to the exhaust duct 41 side is circulated so as to return to the drying unit duct 43 through the lower flexible duct 42.
When the compressor 53 is driven, a high-temperature and high-pressure refrigerant flows from the compressor 53 to the condenser 52, where it dissipates heat and liquefies. At this time, the air passing through the condenser 52 of the drying unit duct 43 is heated by the condenser 52. The liquefied refrigerant passes through the capillary tube and is depressurized, and then flows into the evaporator 51 where it takes away the surrounding heat and vaporizes. At this time,
The air passing through the evaporator 51 of the drying unit duct 43 is cooled by the evaporator 51.

The refrigerant vaporized by the evaporator 51 returns to the compressor 53, is compressed again, and is discharged as a high-temperature and high-pressure refrigerant.
In this way, the warm air heated by the condenser 52 is supplied into the drum 30 to heat the laundry in the drum 30, deprive the laundry of moisture, and dry the laundry. The air deprived of moisture is cooled in the process of passing through the evaporator 51 of the drying unit duct 43, and the moisture contained in the air is condensed and dehumidified. The dehumidified air is heated and warmed in the process of passing through the condenser 52 again, and circulates so that the warm air is supplied into the drum 30. As the air in the water tub 6 is circulated through the circulation air passage 48 in this manner, the laundry in the drum 30 is dried.
Thus, the operation of the “standard” operation course in which the operation from “washing” to “drying” is automatically completed. The time required for this driving course is 6 hours.
In addition, when the washing key 63a is selected and executed in the selection operation unit 63, the washing process to the final dehydration process described above are performed and the process is terminated. When the drying key 63c is selected and executed, only the above-described drying process is performed.

Here, the operation method of the reservation operation key 67 for setting the above-described reservation time of the operation panel unit 60 will be described in detail with reference to FIGS. The reservation operation key 67 is used for setting a reservation such as a start time and an end time of the driving course.
When the power operation unit 61 is turned on, the current time (20:00) is displayed on the liquid crystal panel 75 (steps S1, 2) (see FIG. 6A). This current time is measured by a timer 80 connected to the control device 10.
As described above, the automatic operation from “washing” to “drying” is selected as the “standard” course (step S3). Subsequently, when the reservation operation key 67 is pressed, the required time (6 hours) required for the selected driving course is displayed (steps S4, 5) (see FIG. 6B).
This required time is displayed on the liquid crystal panel 75 as “required driving time 6 hours”. If the user starts driving from this display, the driving will end 6 hours from now. Recognize And the reservation end time can be set on the operation end reservation screen described later,
It can be recognized that the current time is 20:00 after 6 hours from 20:00.

When the user presses the reservation operation key 67 again (Y in Step S6), the operation end time setting screen is displayed on the liquid crystal panel 75, and the reference time (for example, 6:00) is lit (Step S7) ( (Refer FIG.6 (c)). When the dial 72 is turned at this time, the displayed time is changed, and the user adjusts the time (for example, 7:40) at which the user wants to finish the washing (steps S9, 10) (FIG. 6B). )reference).
When the reservation end time is reached, the push button 73 is pressed (step S11),
An automatic “standard” driving course from “washing” to “drying” and a reservation end time are set (step S13), and the reservation end time (7:40) set based on a preset program is set. Operation is started so that the set operation course is completed (step S14). And driving | operation complete | finishes when the required time (6 hours) displayed by step S5 has passed since the driving | operation start (step S15).
When the push button 73 in step S11 is pressed, if the selected reservation end time is selected before the total time (26:00) of the current time and the required time, the set operation course is set by the reservation time. Since the process cannot be completed, “not reserved” is flashed on the liquid crystal panel (steps S12 and S16 (see FIG. 6G)).

On the other hand, when the user further presses the reservation operation key 67 by the above-described step S11 (
In step S8), an operation start reservation screen is displayed on the liquid crystal panel 75 (step S17) (see FIG. 6E), and a screen on which the operation start time can be reserved is displayed. At this time, similarly to the above-described operation end reservation screen, the dial 72 is rotated to select the start time (23:00) (steps S19 and 20) (see FIG. 6F).
By pushing the push button 73 in this state (step S21), an automatic “standard” driving course from “washing” to “drying” and a reservation start time are set (step S22). Then, the operation is started when the reserved start time (23:00) is reached, and the operation is ended when the required time (6 hours) displayed in step S5 has elapsed (steps S23 and S24).
If the reservation operation key 67 is further pressed again by step S21 (step S18), the course required time of step S5 is displayed again on the liquid crystal panel 75.
That is, when the reservation operation key 67 is pressed a plurality of times, a course required time display screen, a driving end reservation screen, and a driving start display screen are sequentially displayed.
As shown in FIG. 7, the time required for step S5 varies depending on the selected operation course. For example, when the washing / drying operation course 63a is selected and the “speedy” operation course is selected with the dial 72, The required time is displayed for 5 hours as shown in FIG. Accordingly, when setting the time on the operation end reservation screen, unless it is set to the time after 5 hours from the current time, the reservation setting impossibility is displayed as in step S16, and the reservation cannot be made.

According to the above-described embodiment, the following effects can be obtained.
By pressing the reservation operation key 67, an operation end reservation screen for setting the time for ending the operation of the drum type washing and drying machine and an operation start reservation screen for setting the time for starting the operation of the drum type washing and drying machine can be reserved. Since the time can be reserved by calling the liquid crystal panel 75 and selecting either of them, the drum type washing and drying machine can start or end the operation based on the set time and the time counted by the timer 80. The user can select the reservation setting of the time to end the operation of the drum type washing machine and the time to start the operation for the convenience of the user, which is convenient.
The liquid crystal panel 75 displays the required time or end time for the operation of the drum type washer / dryer, so that the user looks at the required time and reserves the start time when the user makes a reservation. It is possible to recognize whether the operation will be completed by the time at which it is desired to be completed. In addition, when making a reservation for the driving end time, the user can grasp the driving end time and set a time after the grasping end time, so that the driving stops before washing is completed. Can avoid the problem.

In addition, the liquid crystal panel 75 displays the required time or end time for the operation of the washing machine, and the end time set for reservation on the operation end reservation screen is before the required time for the displayed driving course or the displayed end time. When the time before the time is set, “reservation setting impossible” is displayed on the liquid crystal panel 75 and the user is notified, so the user recognizes the display and sets the reservation for the time before the end time again. Can do. Therefore, the problem that the operation is stopped before the washing is completed can be avoided.
In addition, since a selection operation unit 63 that can select one of a plurality of driving courses, a setting button 68, and a dial 72 are provided and the required time based on the selected driving course is displayed on the liquid crystal panel 75, the user can select each driving course. The time required for the course can be recognized, making it easier to set a time reservation.
Further, as a part of the reserved time setting means, the time is selected using the dial 72, so that it is easy for the user to use.

The liquid crystal panel 75 displays “required operation time of 6 hours” in step S5, but may display “required settable time for operation end is 6 hours later”. Further, when the current time at that time is 20: 0, “the settable time for the operation end reservation time is after 26:00” may be displayed to display the operation end time.
In addition, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.
