FIG. 4 is a flow chart showing a part of the control process performed by the control device 38 of the drum-type washer-dryer S of FIG. 1. FIG. 5 is a flow chart showing another part of the control process performed by the control device 38 of the drum-type washer-dryer S of FIG. 1.

As shown in FIG. 4, if the power switch 39 (refer to FIG. 1) is turned on by the user's operation, the control device 38 performs status confirmation of the drum-type washer-dryer S and performs drum-type washing The initial setting of the clothes dryer S (step S101).

In response to the operation of the user's operation key 13, the control device 38 sets a washing schedule (step S102).

Next, in step S103, the control device 38 monitors the instruction input from the operation key 12 of the operation panel 6 as the start switch, and confirms the presence or absence of the start switch signal. If it is not confirmed (in the case of "No" in step S103), step S103 is repeated. When the control device 38 confirms that the switch signal has been started (when there is a "Yes" in step S103), the control device 38 proceeds to step S104 and executes the detection process of the amount of washing.

This amount of washing detection is based on the dry cloth before the washing water is supplied. When the washing and dewatering tank 3 is rotated in one direction, the speed is increased to the prescribed first from the prescribed first rotation speed. The integrated value of the driving current of the motor 4 during the period up to 2 rotation speeds is used to detect the mass of the laundry 36. After that, based on the detected mass of the laundry 36, an appropriate amount (lotion amount) of the lotion to be used is calculated, and a process for detecting the amount of lotion (step S104) is performed. The calculation of the washing amount is performed by referring the control device 38 to a predetermined comparison table for the relationship between the mass of the laundry 36 and the washing amount used.

The control device 38 displays the calculated washing amount on the display 14 of the operation panel 6 (step S105). If the user puts the displayed lotion into the lotion tray 7 and a predetermined time (for example, 1 minute) has passed, the control device 38 opens the water supply solenoid valve (not shown) and applies the lotion The tray 7 carries water. As a result, the lotion is supplied into the outer tank 2. Simultaneously with the scattered water of the lotion tray 7, the washing water 54 is sprayed toward the clothes filter 8 from the washing nozzle 53, and the clothes line 8 and the clothes line 29 are attached to the clothes filter 8 Cotton wool on the wall surface is washed off. In addition, this cotton batting was caused by the previous drying operation. The washing water 54a containing cotton wool flows from the lower part of the clothes drying pipe 29 through the bellows hose 29a to the outer tank 2, the water receiving part 2f, and the drainage hose 26. The cotton wool is captured and concentrated in the silk filter At the network 27 (step S106).

Next, the control device 38 closes the water supply solenoid valve (not shown) when the water level in the outer tank 2 reaches the preset dissolving water level, and stops the water supply and washing water 54 (step S107).

Thereafter, the control device 38 circulates the water in the outer tank 2 from the drain hose 26 through the circulation hose 24a and the circulation hose 24c by rotating the circulation pump 24 in the reverse direction. Thereby, the lotion which accumulates in the bottom part of the outer tank 2 and the recessed part 2f is melt | dissolved (step S108).

At step S109, front washing is performed. In this front-loading washing, the washing and dewatering tank 3 is rotated forward and backward alternately (addition of forward and reverse and 35 rotations to 45 rotations per minute), and the circulation pump 24 is rotated forwards and forwards. The washing water in the outer tub 2 is sprayed from the drain hose 26 through the circulation hose 24a and the circulation hose 24b to the laundry 36 in the laundry and dehydration tank 3.

At this time, the laundry 36 is repeatedly lifted and dropped by the lifter 3b provided on the inner peripheral wall surface of the washing and dewatering tank 3. Thereafter, the control device 38 intermittently performs the rotation of the washing and dewatering tank 3 and the operation of the circulation pump 24, and refers to the water level sensing during the stopping period of the washing and dewatering tank 3 and the circulation pump 24. The water supply solenoid valve (not shown) is opened on the side of the detection signal of the water heater (not shown), so that the water in the outer tank 2 is made up by adding water and washing water 54 in a way that does not exceed the set water level. supplement. This operation is repeated several times.

Next, the control device 38 executes a formal laundry process (step S110). Specifically, the control device 38 rotates the washing and dewatering tank 3 forward and backward alternately (addition of forward and reverse and 35 rotations to 45 rotations per minute), and forward rotation of the circulation pump 24, which is the same as the foregoing The washing water of the outer tub 2 is sprayed on the floor to the laundry 36. Finally, the control device 38 stops the operation of the circulation pump 24 to stop the circulation of the washing water, and simultaneously rotates the washing and dewatering tank 3 in a short cycle in a positive and negative direction while loosening the laundry 36 for a specific time. The on-line operation is completed, and the formal laundry process is completed (step S110).

As shown in FIG. 5, in step S111 performed after step S110 (refer to FIG. 4), the control device 38 performs the first washing.

In this washing, the control device 38 first opens the drain valve 25 and drains the water in the outer tank 2. The control device 38 directs the washing and dewatering tank 3 to a single direction after detecting the completion of the drainage by a water level sensor (not shown) (in the present embodiment, it is a drum-type washer-dryer). The front side (front side) of S is rotated counterclockwise during observation, and the washing water contained in the laundry 36 is centrifuged.

After that, the control device 38 opens the water supply solenoid valve (not shown), and supplies tap water to the inside of the outer tank 2, and also supplies washing water 54 to the inside of the outer tank 2. Next, in the same way as the formal laundry process (step S110), while rotating the washing and dewatering tank 3 in reverse rotation (35 rotations to 45 rotations per minute), the circulation pump 24 is rotated in the positive direction to accumulate the outside The washing water at the bottom of the tank 2 is circulated in a manner that the washing water is sprinkled to the washing 36, and washing is performed.

Next, the control device 38 detects the accumulation in the outer tank 2 with a water level sensor (not shown) in a state where the rotation of the washing and dewatering tank 3 and the operation of the circulation pump 24 are stopped. The water level of the wash water at the bottom of the bottom is supplemented by the make-up water and the wash water 54 in such a way that the water level does not exceed the set water level.

After that, the washing and dewatering tank 3 is rotated in the reverse direction (35 to 45 rotations per minute), and the circulation pump 24 is rotated in the forward direction so as to accumulate at the bottom of the outer tank 2 (recessed portion 2f). The washing water is circulated in a manner that the washing water is sprinkled on the laundry 36, and washing is performed.

After that, in a state where the circulation pump 24 is stopped and the circulation of the washing water is stopped, the control device 38 rotates the washing and dewatering tank 3 forward and backward in a short period to perform loosening operation.

In step S112, the same washing process (second washing process) as the first washing process (step S111) is performed except that a softener is put into the outer tank 2.

At step S113, a dehydration process is performed. The control device 38 directs the washing and dewatering tank 3 in a single direction with the drain valve 25 opened (in this embodiment, it is observed from the front (front) of the drum-type washer-dryer S Counterclockwise), and the laundry water contained in the laundry 36 is centrifuged.

Then, the user moves to the clothes drying process (step S114). In FIG. 3, the air flow during the air circulation caused by the fan 28 during the drying process is shown. In the clothes drying process, the washing and dewatering tank 3 is rotated forward and backward while the drain valve 25 is opened. After that, the control device 38 drives the fan 28 and blows the warm air 43 heated by the heater 31 to the laundry 36 in the washing and dewatering tank 3. When the warm air 43 is blown, the water evaporates from the laundry 36. The air that has taken moisture from the laundry 36 and becomes humid flows through the clothes drying line 29, and then opens the cooling water valve (not shown) to flow out from the cooling water supply pipe 51 to The cooling water 52 flowing in parallel on the wall surface in the clothes drying pipe 29 contacts, and is thereby dehumidified. The air that has been dehumidified and becomes low-humidity and low-temperature is sucked into the fan 28, heated again by the heater 31, and blown again to the laundry 36 in the washing and dewatering tank 3. The evaporation of the water from the laundry 36 and the dehumidification of the air are performed repeatedly, and the laundry 36 is dried. In addition, the cooling water 52 flowing out to the wall surface in the clothes drying duct 29 is discharged through the drain opening 21 through the drain hose 26. In addition, the lint such as silk waste generated during the drying process enters into the drying line 29 with the flow of air, and part of it is cooled by the cooling water 52 flowing on the wall surface of the drying line 29 It was washed down and captured and concentrated on the silk filter 27, and the remaining part was captured and concentrated on the clothes filter 8. The cotton wool captured in 8 places in the clothes drying filter was washed off during the next water supply project during washing.

By carrying out a series of projects as described above, the washing and drying operation system of the drum-type washer-dryer S caused by the control device 38 is completed.

In the washer-dryer constructed in this way, the clothes filter 8 is arranged above the outer tank 2 and the clothes filter 8 is positioned above the water level where the water is supplied to the outer tank 2. Thereby, the water-sealing structure for attaching and detaching the clothes-drying filter case 8a in which the clothes-drying filter 8 is built can be eliminated, and the cost can be reduced. In addition, since the clothes drying filter 8 is washed by washing water 54 during the water supply of washing, and the washing water 54 is used as washing water, it is not necessary to dry clothes in the laundry. The amount of water used in the process is increased to automatically clean the clothes filter. This can prevent an increase in the cost of water used.

Next, a drum-type washer-dryer according to a second embodiment of the present invention will be described with reference to FIG. 6. Fig. 6 is a schematic cross-sectional view of a washer-dryer showing the flow of washing water when washing water is supplied. The configuration common to the first embodiment will not be described repeatedly.

The difference from FIG. 2 of the first embodiment is that the washing water 54 will slightly touch the clothes filter 8 provided between the fan unit 40 and the clothes drying pipe 29. In a flat manner, the clothes drying screen 8 is installed obliquely with respect to the flow path of the clothes drying pipe 29. By setting the drying filter 8 obliquely, since the area of the filter can be increased, the reduction in the air volume caused by the clogging in the drying can be suppressed, and the increase in the drying time can be controlled. inhibition. In addition, by making the washing water 54 slightly perpendicular to the plane of the clothes filter 8, it is easy to peel off the cotton wool from the filter. As a result, the cleaning performance of the clothes filter 8 is improved.

Next, a drum type washer-dryer according to a third embodiment of the present invention will be described with reference to Figs. 7 and 8. FIG. 7 is a schematic cross-sectional view of a washer-dryer showing the flow of washing water when washing water is supplied. FIG. 8 is a schematic cross-sectional view of a washer-dryer shown for air flow in a clothes drying project. The configuration common to the first embodiment will not be described repeatedly.

The difference from FIG. 2 of the first embodiment is that an air suction valve for guiding the air in the frame 1 to the fan unit 40 is provided between the clothes drying screen 8 and the clothes drying pipe 29. 44 and intake pipe 44a. Similar to the first embodiment, the washing water 54 is sprayed toward the clothes filter 8 from the washing nozzle 53 when the washing water is supplied or the washing water is replenished at the same time, and is attached to the clothes filter The cotton wool under the 8 and the wall surface of the clothes drying pipe 29 washed off. In addition, this cotton batting was caused by the previous drying operation. The suction valve 44 is opened and closed halfway after the drying process. However, the suction valve 44 does not leak the washing water 54 attached to the suction valve 44 into the housing 1 due to the opening and closing. An intake pipe 44a is provided above the intake valve 44 and provided with an intake port.

In the first half of the drying process, the washing and dewatering tank 3 was rotated forward and backward with the drain valve 25 opened. After that, the control device 38 drives the fan 28 and blows the warm air 43 heated by the heater 31 to the laundry 36 in the washing and dewatering tank 3. When the warm air 43 is blown, the water evaporates from the laundry 36. The air that has taken moisture from the laundry 36 and becomes humid flows through the clothes drying line 29, and then opens the cooling water valve (not shown) to flow out from the cooling water supply pipe 51 to The cooling water 52 (not shown) flowing in parallel on the wall surface in the clothes drying pipe 29 contacts and is dehumidified by this. The air that has been dehumidified and becomes low-humidity and low-temperature is sucked into the fan 28, heated again by the heater 31, and blown again to the laundry 36 in the washing and dewatering tank 3. The evaporation of the water from the laundry 36 and the dehumidification of the air are performed repeatedly, and the laundry 36 is dried.

In the second half of the drying process, as shown in FIG. 8, the heater 31 is turned OFF, and the cooling water 52 is stopped. After that, the external air 46 sucked from the gap in the lower part of the base 1h by opening the suction valve 44 is flowing on the side of the outer tank 2 while receiving the heat from the outer tank 2, the motor 4, and the fan 28. The temperature rises, and it is sucked into the fan 28 together with the high-temperature air 47 in the frame that accumulates on the outer tank 2 and the space of the frame 1 until the first half of the clothes are dried. The air 48 sucked into the frame body is blown to the laundry 36, and the water evaporates from the laundry 36. When the suction valve 44 is opened, the air path from the clothes drying line 29 to the clothes filter 8 is blocked. Therefore, moisture is taken from the laundry 36 and becomes moist air through the drain. 21 is passed through the drainage hose 26 and passed through the water trap of the drainage trap 23 to be discharged to the drainage port 22. By repeatedly evaporating the water from the laundry 36 and discharging the humidified air due to the evaporation to the drain 22, the laundry 36 is further dried.

In this way, if the drum-type washer-dryer is operated according to the third embodiment, the waste heat can be used to reduce the power consumption of the heater 31 in the latter half of the drying process. The cooling system does not use cooling water after the drying process. Therefore, the amount of water used can be reduced. The waste heat drying clothes are stored in the laundry until the first half of the drying operation. 36, Heat from the inside of the casing 47 in the space above the washing and dewatering tank 3, the outer tank 2 and the outer tank 2 and the space of the frame 1, and dry outside air 46. In addition, the suction line 44a provided with a suction port above the suction valve 44 can prevent water leakage due to the opening and closing of the suction valve 44.
