  Next, the control device 38 will be described. The control device 38 includes a microcomputer, a drive circuit and the like, and also includes an on / off signal of the operation buttons 12 and 13 shown in FIG. 1 and an input circuit of an output signal from various sensors. The microcomputer also receives various information signals from the user's operation, the washing process and the drying process. The microcomputer is connected to the motor 4, the feed water solenoid valve (not shown), the drain valve 25, the fan unit 40 and the like via a drive circuit, and controls the opening / closing, rotation and energization of these. In addition, in order to notify the user of information regarding the drum-type washing / drying machine S, the display 14 and a buzzer (not shown) are also controlled.

  FIG. 4 is a flow chart showing a part of control processing executed by the control device 38 of the drum-type washing and drying machine S of FIG. FIG. 5 is a flow chart showing another part of the control process executed by the control device 38 of the drum-type washing and drying machine S of FIG.

  As shown in FIG. 4, when the power switch 39 (see FIG. 1) is turned on by the operation of the user, the control device 38 confirms the state of the drum type washing / drying machine S and initializes the drum type washing / drying machine S. (Step S101).

  In response to the operation of the operation button 13 by the user, the control device 38 sets a washing course (step S102).

  Next, in step S103, the control device 38 monitors the instruction input from the operation button 12 as the start switch of the operation panel 6, and confirms the presence or absence of the start switch signal. If not confirmed (in the case of "absent" in step S103), step S103 is repeated. When the controller 38 confirms the start switch signal ("YES" in step S103), the controller 38 proceeds to step S104 to execute the detergent amount detection process.

  This detergent amount detection accelerates from the prescribed first rotational speed to the prescribed second rotational speed when the washing and dehydration tank 3 is rotated in one direction in the dry cloth state before water supply to the washing water The mass of the laundry 36 is detected based on the drive current integrated value of the motor 4 during the period. Then, an appropriate amount (detergent amount) of the detergent to be used is calculated based on the detected weight of the laundry 36, and the step of detecting the amount of detergent (step S104) is performed. The calculation of the amount of detergent is performed by the controller 38 referring to a control table that defines the relationship between the weight of the laundry 36 and the amount of detergent used.

  The control device 38 displays the calculated amount of detergent on the display 14 of the operation panel 6 (step S105). When the user inserts the detergent amount of this indication into the detergent tray 7 and the predetermined time (for example, 1 minute) has passed, the control device 38 opens the water supply solenoid valve (not shown) and sprinkles water on the detergent tray 7 Do. Thus, the detergent is supplied into the outer tank 2. Further, simultaneously with the watering of the detergent tray 7, washing water 54 is jetted from the washing nozzle 53 toward the drying filter 8 to wash away lint and the like adhering to the lower surface of the drying filter 8 and the wall surface of the drying duct 29. This lint was generated in the previous drying operation. The washing water 54a containing lint flows from the lower part of the drying duct 29 through the outer tank 2, the water receiving portion 2f and the drainage hose 26 via the bellows hose 29a, and the lint is collected by the lint filter 27 (step S106) ).

  Next, when the water level in the outer tank 2 reaches the detergent dissolution water level set in advance, the control device 38 closes the water supply solenoid valve (not shown) to stop the water supply and the washing water 54 (step S107).

  Then, the control device 38 circulates the water in the outer tank 2 from the drainage hose 26 via the circulation hose 24 a and the circulation hose 24 c by rotating the circulation pump 24 in reverse. As a result, the detergent accumulated in the bottom of the outer tank 2 and the recess 2f is dissolved (step S108).

  In step S109, pre-washing is performed. In this pre-washing, the washing water of the outer tub 2 is drained by rotating the circulation pump 24 forward while rotating the washing and dewatering tub 3 alternately forward and reverse alternately (35 to 45 revolutions per minute). 26, the laundry 36 in the washing and dewatering tank 3 is dropped onto the laundry 36 via the circulation hose 24a and the circulation hose 24b.

  At this time, the laundry 36 is lifted by the lifter 3 b provided on the inner peripheral wall surface of the washing and dewatering tank 3 and repeats the falling motion. Then, the control device 38 intermittently performs the rotation of the washing and dehydration tank 3 and the operation of the circulation pump 24, and detects the detection signal of the water level sensor (not shown) during the stop period of the washing and dehydration tank 3 and the circulation pump 24. The water supply solenoid valve (not shown) is opened while making reference, and the washing water in the outer tub 2 is replenished with the replenishing water and the washing water 54 so that the water level does not exceed the set water level. This operation is repeated several times.

  Next, the control device 38 executes a main washing process (step S110). Specifically, the controller 38 rotates the circulation pump 24 forward while rotating the washing and dewatering tank 3 alternately forward and reverse alternately (35 rotations to 45 rotations per minute). Put the wash water on 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 performs an operation for loosening the laundry 36 for a predetermined time while alternately rotating the washing and dewatering tank 3 forward and reverse in a short cycle. The main washing step (step S110) is ended.

  As shown in FIG. 5, in step S111, which is executed subsequent to step S110 (see FIG. 4), the control device 38 executes a first rinse.

  In this rinse, the controller 38 first opens the drain valve 25 to drain the water in the outer tank 2. The controller 38 detects that the drainage has been completed by means of a water level sensor (not shown), and then looks at the washing and dewatering tank 3 in one direction (in the present embodiment, from the front (front) of the drum type washer / dryer S. Counterclockwise) to centrifugally dewater the washing water contained in the laundry 36.

  Thereafter, the controller 38 opens the water supply solenoid valve (not shown) to supply tap water into the outer tank 2, and the wash water 54 is also supplied into the outer tank 2. Next, similar to the main washing step (step S110), the circulating pump 24 is rotated forward while the washing and dewatering tank 3 is reversely rotated (35 rotations to 45 rotations per minute) and accumulated in the bottom of the outer tank 2. The rinse water is circulated so as to sprinkle on the laundry 36, and the rinse is performed.

  Next, the control device 38 detects the water level of the rinse water accumulated at the bottom of the outer tank 2 with the water level sensor (not shown) while stopping the rotation of the washing and dehydration tank 3 and the operation of the circulation pump 24. The rinse water in the outer tank 2 is replenished with makeup water and washing water 54 so as not to exceed the set water level.

  Then, while rotating the washing and dewatering tank 3 in reverse rotation (35 to 45 rotations per minute), the circulation pump 24 is rotated forward, and the rinse water collected in the bottom (recessed portion 2f) of the outer tank 2 is washed 36 Circulate so as to sprinkle on and run rinse.

  After that, with the circulation pump 24 stopped and the circulation of rinse water stopped, the controller 38 rotates the washing and dehydration tank 3 forward and reverse in a short cycle to perform the loosening operation.

  In step S112, the same rinse step (second rinse step) as the first rinse step (step S111) is performed except that the softener is introduced into the outer tank 2.

  In step S113, a dehydration process is performed. The control device 38 rotates the washing and dewatering tank 3 in one direction (in the present embodiment, counterclockwise as viewed from the front (front) of the drum-type washing and drying machine S) with the drainage valve 25 kept open. The washing water contained in the laundry 36 is centrifugally dewatered.

  Next, the process proceeds to the drying step (step S114) by the selection of the user. FIG. 3 shows the flow of air during circulation and blowing by the fan 28 during the drying process. In the drying step, the washing and dewatering tank 3 is rotated forward and reverse while the drainage valve 25 is kept open. Then, the control device 38 drives the fan 28 to blow the warm air 43 heated by the heater 31 onto the laundry 36 in the washing and dewatering tank 3. By blowing the warm air 43, the moisture evaporates from the laundry 36. Air taken from the laundry 36 and moistened flows into the drying duct 29 and then flows from the cooling water supply pipe 51 to the wall in the drying duct 29 by opening the cooling water valve (not shown). Dehumidification is achieved by contact with water 52. The dehumidified, low-humidity, low-temperature air is sucked into the fan 28, reheated by the heater 31, and blown again to the laundry 36 in the washing and dewatering tank 3. The laundry 36 is dried by repeating the evaporation of water from the laundry 36 and the dehumidification of air. The cooling water 52 that has flowed to the wall surface in the drying duct 29 is drained by the drainage hose 26 through the drainage port 21. In addition, lint such as lint generated at the time of drying gets into the air flow and enters the drying duct 29, and a part is washed away by the cooling water 52 flowing on the wall surface of the drying duct 29 and dried on the lint filter 27 It is collected by the filter 8. The lint collected by the drying filter 8 is washed away in the water supply process at the next washing.

  By performing the above-described series of processes, the washing and drying operation process of the drum-type washing and drying machine S by the control device 38 is completed.

  In the washing and drying machine configured as described above, the drying filter 8 is disposed above the outer tank 2 so that the drying filter 8 is located above the water level supplied to the outer tank 2. As a result, the water sealing structure for attaching and detaching the drying filter case 8a incorporating the drying filter 8 can be eliminated, and the cost can be reduced. In addition, since the dry filter 8 is washed with the wash water 54 at the time of water supply for washing, and the wash water 54 is used as wash water, the dry filter can be automatically washed without increasing the amount of water used for washing and drying. . This can prevent an increase in the cost of water used.

  Next, a drum-type washing and drying machine according to a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a schematic cross-sectional view of a washing and drying machine showing the flow of washing water at the time of washing and water supply. The same description as that of the first embodiment will not be repeated.

  The difference between FIG. 2 and FIG. 2 of the first embodiment is that the drying filter 8 is a part of the drying duct 2 in such a manner that the washing water 54 hits the plane of the drying filter 8 installed between the fan unit 40 and the drying duct 29 almost perpendicularly. It is installed obliquely to the flow path. Since the area of the filter can be increased by installing the drying filter 8 obliquely, it is possible to suppress the decrease in air volume due to clogging during drying and to suppress the increase in drying time. In addition, since the washing water 54 hits the surface of the dry filter 8 almost perpendicularly, the lint can be easily removed from the filter. Thereby, the cleaning property of the drying 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. FIG. 7 is a schematic cross-sectional view of a washing and drying machine showing the flow of washing water at the time of washing and water supply. FIG. 8 is a schematic cross-sectional view of a washer / dryer showing the flow of air during the drying process. The same description as that of the first embodiment will not be repeated.

  A difference of the first embodiment from FIG. 2 is that an intake valve 44 and an intake duct 44a for guiding the air in the housing 1 to the fan unit 40 are provided between the drying filter 8 and the drying duct 29. is there. As in the first embodiment, washing water 54 is jetted from the washing nozzle 53 toward the drying filter 8 simultaneously with washing water supply and washing water replenishment, and adheres to the lower surface of the drying filter 8 and the wall surface of the drying duct 29. Wash off lint and other lint. This lint was generated in the previous drying operation. The intake valve 44 is opened and closed in the latter half of the drying process, and the intake duct 44a is provided with an intake port above the intake valve 44 so that the wash water 54 attached to the intake valve 44 by the opening and closing does not leak into the housing 1. Is attached.

  In the first half of the drying process, the washing and dewatering tank 3 is rotated in the forward and reverse directions with the drainage valve 25 kept open. Then, the control device 38 drives the fan 28 to blow the warm air 43 heated by the heater 31 onto the laundry 36 in the washing and dewatering tank 3. By blowing the warm air 43, the moisture evaporates from the laundry 36. Air taken from the laundry 36 and moistened flows into the drying duct 29 and then flows from the cooling water supply pipe 51 to the wall in the drying duct 29 by opening the cooling water valve (not shown). Dehumidification is achieved by contact with water 52 (not shown). The dehumidified, low-humidity, low-temperature air is sucked into the fan 28, reheated by the heater 31, and blown again to the laundry 36 in the washing and dewatering tank 3. The laundry 36 is dried by repeating the evaporation of water from the laundry 36 and the dehumidification of air.

  In the latter half of the drying process, as shown in FIG. 8, the heater 31 is turned off and the cooling water 52 is stopped. Then, by opening the intake valve 44, the external air 46 sucked from the gap in the lower part of the base 1h receives the exhaust heat of the outer tank 2, the motor 4 and the fan 28 while flowing through the side surface of the outer tank 2, The air is drawn into the fan 28 together with the high temperature inside air 47 stored in the upper surface of the outer tank 2 and the space of the housing 1 by the first half of the drying. By blowing the suctioned air 48 inside the case to the laundry 36, the moisture evaporates from the laundry 36. Since the air path from the drying duct 29 to the drying filter 8 is closed by opening the intake valve 44, the air moistened by removing moisture from the laundry 36 passes through the drainage port 21 through the drainage hose 26, and the drainage trap The water seal 23 is broken and drained to the drainage port 22. The laundry 36 is further dried by repeating the evaporation and evaporation of the moisture from the laundry 36 and discharging the wet air to the outlet 22.

  Thus, according to the operation process of the drum type washing and drying machine according to the third embodiment, the upper surface of the laundry 36, the washing and dewatering tank 3, the outer tank 2 and the outer tank 2 and the housing 1 The amount of power consumption of the heater 31 in the latter half of the drying process can be reduced by the residual heat drying using the heat stored in the case internal air 47 stored in the space and the dried external air 46, and the second half of the drying process is cooled Because water is not used, the amount of water used can be reduced. Further, the intake duct 44a having the intake port above the intake valve 44 can prevent water leakage due to the opening and closing of the intake valve 44.
