The washing / drying machine 10 can execute automatic operation by selectively combining the steps of “washing”, “rinsing”, “dehydration”, and “drying”. The laundry dryer 10 includes, as automatic operations, a washing operation that mainly performs a washing process, a washing and drying operation that mainly performs a washing process and a drying process, and a drying operation that mainly performs a drying process. As shown in FIG. 5, the user selects a desired automatic operation by operating a “washing” key 611, a “washing” key 612, and a “drying” key 613 provided on the operation panel 13. In this case, the washing operation is selected when the “washing” key 611 is operated, the washing operation is selected when the “washing” key 612 is operated, and the drying operation is selected when the “drying” key 613 is operated. Selected.

∙ Each automatic driving has multiple courses. In the course of the content of the selected automatic operation, the combination and time of each process of “washing”, “rinsing”, “dehydration”, “drying” are changed to the contents recommended by the manufacturer or arbitrarily of the user Is to do. The user selects a desired course from the courses displayed on the course display unit 62. For example, in the present embodiment, a “standard” course, a “scenting” course, and a plurality of other types of courses are set for the “washing” operation.

Next, the “standard” course and the “scenting” course will be described.
The “standard” course and the “scenting” course are for performing each process based on the setting contents shown in FIG. In this case, depending on the weight of the laundry, there are three levels of “high weight”, “medium weight”, and “small weight”, that is, three levels of “high”, “medium”, and “low” in the rinse water level. Is set. The “Standard” course realizes the standard washing operation recommended by the manufacturer for each process of the washing operation. In the “standard” course, as shown in FIG. 6, detailed setting values in each process, for example, a rinsing water level, a finishing agent charging water level, a rinsing time, and the like are set as standard setting contents as standard specifications. On the other hand, the “scenting” course realizes an operation for improving the scenting action by the finishing agent. In the “scenting” course, detailed setting values in each process are set as a scenting specification with reference to a standard setting value.

Specific control contents will be described with reference to FIGS. Here, a case where either the “standard” course or the “scenting” course is selected for the washing operation will be described. The user operates the “ON” key 63 on the operation panel 13 shown in FIG. The user operates the operation panel 13 to set various operations and course contents, that is, a “standard” course or a “scented” course.

In the washing operation, the washing process, the rinsing process, and the dehydrating process are each performed once or more. In this case, the rinse process performed lastly among the rinse processes performed a plurality of times is referred to as a final rinse process. In this final rinsing step, the control device 16 controls the water supply input device 30 to input the finishing agent stored in the finishing agent storage unit 312 of the case 31 into the water tub 19 and then rinse the laundry. Do. Of the dehydration processes performed a plurality of times, the last dehydration process is referred to as a final dehydration process. And among the dehydration processes performed a plurality of times, the dehydration process performed immediately before the final rinse process is referred to as a final pre-rinse dehydration process.

As shown in FIG. 7, when the power is turned on (power is turned on), the control device 16 waits until the “start” key 64 is operated (NO in step S11). The user operates the “washing” key 611 to select the “standard” course or the “scented” course of the washing operation, and then operates the “start” key 64. When the “start” key 64 is operated (YES in step S11), the control device 16 proceeds to step S12 and detects the weight of the laundry. For example, the weight of the laundry is detected as follows. That is, the control device 16 drives the motor 211 to rotate the rotating tub 18. And the control apparatus 16 detects the weight of the laundry in the rotation tub 18 by detecting the electric current, rotation speed, etc. of the motor 211 which change according to the load amount of the laundry in the rotation tub 18.

Next, in step S13, the control device 16 determines whether the laundry weight detected in step S12 corresponds to one of the three levels of “large weight”, “medium weight”, and “small weight” shown in FIG. Thus, the rinsing water level and the like in the rinsing process are set. In this case, as shown in FIG. 6, the control device 16 sets the rinse water level to Wh [L] when the laundry weight is large, and sets the rinse water level to Wm [L] when the laundry weight is medium. When it is a weight, it is set to Wl [L]. Note that Wh, Wm, and Wl are specific numerical values set according to the model of the washing / drying machine 10, and the relationship thereof is Wh> Wm> Wl.

Thereafter, the control device 16 proceeds to step S14, closes the drain valve 231 and opens the first water supply valve 34 to supply water into the water tank 19. Water from an external water source is supplied from the first water supply valve 34 into the water tank 19 via the detergent container 311 of the case 31. At this time, the detergent accommodated in the detergent accommodating portion 311 of the case 31 is dissolved in the water discharged from the first water supply valve 34 and is put into the water tank 19.

Next, the control device 16 proceeds to step S15 and executes a washing process. In the washing process, the control device 16 controls the driving device 21 to rotate the rotating tank 18 and the stirring body 20 relatively at a low speed. Thereby, a washing | cleaning process is performed by producing a water flow in the water tank 19 and stirring the laundry in the rotating tub 18.

When the washing process is finished, the control device 16 proceeds to step S16, opens the drain valve 231 and drains the washing water stored in the water tank 19. Then, the control apparatus 16 transfers to step S17, and performs a 1st dehydration process. In the first dehydration step, the control device 16 rotates the rotating tub 18 and the stirring body 20 integrally at high speed to dehydrate the laundry.

Next, the control device 16 proceeds to Step S18 and executes the first rinsing process. When executing the first rinsing step, the control device 16 closes the drain valve 231 and opens the first water supply valve 34 to supply water into the water tank 19. Then, when the water in the water tank 19 reaches a predetermined rinse water level, the control device 16 controls the driving device 21 to rotate the rotating tank 18 at a low speed. Thereby, the rotating tub 18 and the stirring body 20 are relatively rotated at a low speed, and the laundry in the rotating tub 18 is stirred to rinse the laundry.

The rinsing water level, rinsing time, and stirring time in the first rinsing process of step S18 are set to the same values as the rinsing water level, rinsing time, and stirring time in the final rinsing process of the standard course shown in FIG. Yes. In this case, the stirring time shown in Fig. 6 is, for example, 10 "/ 1 ', means that the rotating tank 18 is rotated continuously or intermittently for 10 seconds within 1 minute. Th, Tm , Tl [sec] is a specific numerical value set according to the model of the washing / drying machine 10, and these relations are Th> Tm> Tl After that, the control device 16 performs step S19. , The drain valve 231 is opened, and the washing water stored in the water tank 19 is drained.

Next, the control device 16 proceeds to step S20, and determines whether or not the “scenting” course is selected for the automatic operation currently being executed, in this case, the washing operation currently being executed. When the “scenting” course is not selected (NO in step S20), the control device 16 determines that the “standard” course is selected, and proceeds to step S21.

When the process proceeds to step S21, the control device 16 proceeds to the standard course operation (standard specification) of FIG. 8, and executes each subsequent process based on the setting contents of the “standard specification” shown in FIG. Specifically, in step S30, the control device 16 determines whether the set water level set for the automatic operation is “high”, “medium”, or “low”. When the set water level is “high”, the control device 16 executes steps S311 to S314 in FIG. 8 based on the setting contents of “high (heavy weight)” in the standard specification in FIG. Further, when the set water level is “medium”, the control device 16 executes step S321 to step S324 in FIG. 8 based on each setting content of “medium (medium weight)” in the standard specification of FIG. Then, when the set water level is “low”, the control device 16 executes steps S331 to S334 in FIG. 8 based on each setting content of “low (small weight)” in the standard specification in FIG.

Here, the basic operation is the same regardless of whether the set water level is “high”, “medium”, or “low”. Therefore, while describing each process in each setting water level in parallel, when description is common in each setting water level, step number S is shown in common like step S3X1, for example. In this case, X = 1 if the set water level is “high”, X = 2 if the set water level is “medium”, and X = 3 if the set water level is “low”.

When the control device 16 determines the set water level in step S30, the control device 16 proceeds to step S3X1 and executes a dehydrating step before final rinsing. As in the other dewatering steps, the control device 16 rotates the rotating tub 18 and the stirring body 20 integrally at high speed to dehydrate the laundry. In this case, when the set water level is “high”, “medium”, or “low”, the rotation speed of the rotary tank 18, that is, the dehydration rotation speed is 900 [rpm]. The dehydration time is 8'00 "when the set water level is" high "(step S311), 6'30" when the set water level is "medium" (step S312), and the set water level is "low" (step S313). 5'00 "in some cases.

Next, the control device 16 proceeds to step S3X2, and executes the final rinsing process. In the final rinsing step, the control device 16 first closes the drain valve 231 and opens the first water supply valve 34. Thereby, water is supplied into the water tank 19 and rinse water is stored in the water tank 19.

Thereafter, the control device 16 further opens the second water supply valve 35 when the water level sensor 25 detects that the water level in the water tank 19 has reached the finishing agent charging water level. As a result, the finishing agent disposed in the finishing agent storage portion 312 of the case 31 is put into the water tank 19. The finishing agent charging water level is Wh-5 [L] when the set water level is “high” (step S312), Wm-5 [L] when the set water level is “medium” (step S322), and the set water level is “low”. In the case of (Step S332), it is Wl-5 [L].

Thereafter, when the water in the water tub 19 reaches the rinsing water level, the control device 16 rotates the rotating tub 18 and the stirring body 20 relatively at a low speed in the same manner as in the other rinsing steps, and the washing in the rotating tub 18 is performed. Stir things. As a result, the laundry is rinsed. In this case, the dewatering rotation speed of the rotary tank 18 is 60 [rpm] regardless of whether the set water level is “high”, “medium”, or “low”. The rinse water level is Wh [L] when the set water level is “high” (step S312), Wm [L] when the set water level is “medium” (step S322), and the set water level is “low” (step S332). In this case, Wl [L].

The rinsing time is Th [s] when the set water level is “high” (step S312), Tm [s] when the set water level is “medium” (step S322), and the set water level is “low” (step S332). In this case, Tl [s]. The stirring time is 10 ″ / 1 ′ when the set water level is “high” (step S312), 8 ″ / 1 ′ when the set water level is “medium” (step S322), and the set water level is “low” (step S332). ) Is 6 ″ / 1 ′.

When the final rinsing process is completed, the control device 16 proceeds to step S3X3, opens the drain valve 231 and drains the rinsing water in the water tank 19. Then, the control apparatus 16 transfers to step S3X4, and performs a final dehydration process. In the final dehydration step, the control device 16 performs the dehydration step with the same set value as before the final rinse. That is, the dehydration rotation speed is 900 [rpm] when the set water level is “high”, “medium”, or “low”. The dehydration time is 8'00 "when the set water level is" high "(step S314), 6'30" when the set water level is "medium" (step S324), and the set water level is "low" (step S334). In this case, the control device 16 ends the washing operation (end of FIG. 7) when the final dehydration step is ended (return of FIG. 8).

On the other hand, when the “scenting” course is selected for the washing operation (YES in step S20 in FIG. 7), the control device 16 proceeds to step S22. If transfering it to step S22, the control apparatus 16 will transfer to the scenting course driving | operation (scenting specification) shown in FIG. 9, and will perform each subsequent process based on the setting content of the scenting specification shown in FIG. This scenting course operation is a standard course operation in that each process of the standard course operation shown in FIG. 8 is executed with the scenting specification shown in FIG. 6 and a hot air supply process is added in step S4X2. And different.
As with standard course operation, the basic operation of each process is the same for this scented course operation regardless of whether the set water level is high, medium, or low. is there.

When the control device 16 determines the set water level in step S40, the control device 16 proceeds to step S4X1, and executes the final pre-rinse dehydration step as in step S3X1 of FIG. In this final pre-rinse dehydration step, the control device 16 increases the rotation speed of the rotary tank 18 as compared with the case of the standard specification. In this case, the dehydration rotation speed in the final rinsing step is 900 [rpm] in the standard specification, but 1000 [rpm] in the scented specification.

In this dehydration step before the final rinse, the control device 16 makes the dehydration time longer according to the set water level than in the case of the standard specification. In this case, the dehydration time of the final rinsing process in the standard specification is 8′00 ″ when the set water level is “high” (step S311), 6′30 ″ when the set water level is “medium” (step S321), and the set water level. In the case of “low” (step S331), it is 5′00 ″. On the other hand, the dehydration time of the final rinsing process in the scenting specification is 9′00 ″ in the case of the set water level “high” (step S411), and the set water level. In the case of “medium” (step S421), it is 7′30 ″, and in the case of the set water level “low” (step S431), it is 5′30 ″.

Next, the control device 16 proceeds to step S4X2 and executes a hot air supply process. When the hot air supply process is executed, the control device 16 drives the hot air supply device 50 to supply hot air into the rotary tank 18 and the water tank 19. Thereby, the laundry in the rotating tub 18 is heated. In this case, the time of the hot air supply process is 10′00 ″ when the set water level is “high” (step S412), 8′00 ″ when the set water level is “medium” (step S422), and the set water level is “low”. In the case of (Step S432), it is 6'00 ". In this case, the warm air supply device 50 functions as a heating means for heating the laundry in the rotating tub 18 before the final rinsing step.

Next, the control device 16 proceeds to step S4X3 and executes the final rinsing process. In this case, the control device 16 inputs the finishing agent into the water tank 19 by the water supply input device 30 from a lower water level than in the case of the standard specification. That is, the finishing agent input water level in the final rinsing process in the scenting specification is lower than that in the standard specification. In this case, the finishing agent input water level is set according to the set water level. When the set water level is “high” (step S413), Wh-20 [L], and when the set water level is “medium” (step S423). Wm-15 [L]. When the set water level is “low” (step S433), the finishing agent is charged simultaneously with the water supply (step S433).

The control device 16 also changes the rinsing water level, rinsing time, rinsing rotation speed, and stirring time according to the set water level with respect to the standard specification. In this case, as shown in FIG. 6, the rinsing water level is lowered, the rinsing time is lengthened, the rinsing rotational speed is lowered, and the stirring time is shortened as compared with the standard specification. That is, in the scenting specification, the rinsing water level in the final rinsing process is Wh-10 [L] in the case of the set water level “high” (step S413), and Wm-7 [in the case of the set water level “medium” (step S423). L] and Wl-5 [L] when the set water level is “low” (step S433).

Further, in the scenting specification, the rinsing time of the final rinsing process is set to Th + 10′00 ″ when the set water level is “high” (step S413), and Tm + 5′00 ″ when the set water level is “medium” (step S423). In the case of the water level “low” (step S433), it is Tl + 3′00 ″. In the scenting specification, the rotation speed of the final rinsing process is the set water level “high” (step S413), “medium” (step S423). , “Low” (step S433), 40 [rpm]. In the scenting specification, the stirring time of the final rinsing process is 6 ″ / 1 ′ when the set water level is “high” (step S413), and 4 ″ / 1 ′ when the set water level is “medium” (step S423). In the case of the set water level “low” (step S433), it is 2 ″ / 1 ′.

When the final rinsing process is completed, the control device 16 proceeds to step S4X4 and opens the drain valve 231 to drain the rinsing water in the water tank 19 as in step S3X3 of FIG. Then, the control apparatus 16 transfers to step S4X5, and performs a final dehydration process. In the final dehydration step, the control device 16 reduces the dehydration rotation speed and shortens the dehydration time according to the set water level as compared with the standard specification. That is, in the scenting specification, the dehydration rotation speed of the final dehydration process is 800 [rpm] in any of the set water level “high” (step S415), “medium” (step S425), and “low” (step S435). The speed is lower than 900 [rpm] in the standard specification. In the scented specification, the dehydration time of the final dehydration process is set to 7'00 "when the set water level is" high "(step S415), and 5'30" when the set water level is "medium" (step S425). In the case of the water level “low” (step S435), it is 4′30 ″. When the final dehydration step is completed (return in FIG. 8), the washing operation is terminated (end in FIG. 7).

According to this, the washing / drying machine 10 includes a standard course for driving with a standard specification recommended by the manufacturer and a scenting course for driving with a specification that places emphasis on scenting with a finishing agent. . And the control apparatus 16 can selectively perform a standard course and a scenting course about automatic driving | operation. That is, the user can arbitrarily select a standard course and a scented course for automatic driving. Therefore, the user can easily add a favorite scent to the laundry by selecting a scented course for automatic driving. As a result, the user can feel the scent effect of the finishing agent more strongly.

In this case, the control device 16 performs the final rinsing process (step S4X2) in the scenting specification (scenting course) for a longer time than the final rinsing process (step S3X2) in the standard specification (standard course). That is, in the final rinsing step, the rinsing time of the scented specification (scented course) is longer than the rinsing time of the standard specification (standard course). According to this, in the final rinsing step of the scented course, the penetration time of the finish with respect to the laundry can be ensured longer than in the case of the standard course. Therefore, in the scenting course, the finishing agent can be sufficiently adhered to the laundry as compared with the standard course, and as a result, the scent effect of the finishing agent can be exhibited more highly.

The rinsing water level in the final rinsing process (steps S3X2, S4X3) is lower in the scented specification (scented course) than in the standard specification (standard course). According to this, the density | concentration of a finishing agent can be raised compared with a standard course in the last rinse process of a scenting course. Therefore, in the scenting course, the finishing agent can be sufficiently adhered to the laundry as compared with the standard course, and as a result, the scent effect of the finishing agent can be exhibited more highly.

The dehydration rotation speed of the rotary tank 18 in the final dehydration process (steps S3X4, S4X5) is lower in the scented specification (scented course) than in the standard specification (standard course). Further, the dehydration time in the final dehydration process (steps S3X4, S4X5) is shorter in the scented specification (scented course) than in the standard specification (standard course). According to these, when the scenting course is selected, it is possible to prevent the water containing the finishing agent from being discharged more than necessary from the laundry in the final dehydration step. Therefore, in the scenting course, the finishing agent can be sufficiently left in the laundry as compared with the standard course, and as a result, the scent effect of the finishing agent can be exhibited more highly.

The finishing agent input water level in the final rinsing process (steps S3X2, S4X3) is lower in the fragrance specification (scenting course) than in the standard specification (standard course). According to this, when the scented course is selected, in the final rinsing step, the finish can be more efficiently permeated into the laundry by introducing the finish from the water level lower than the standard course. . As a result, the scent effect of the finishing agent can be exhibited more highly.

The dehydration rotation speed of the rotary tank 18 in the pre-rinse dehydration process (steps S3X1, S4X1) is faster in the scented specification (scented course) than in the standard specification (standard course). Moreover, the dehydration time in the dehydration step before the final rinse (steps S3X1, S4X1) is longer in the scented specification (scented course) than in the standard specification (standard course). According to these, when the scenting course is selected, the dehydration rate of the laundry can be increased in the pre-rinse dehydration step. Therefore, in the case of the scented course, the water absorption of the laundry in the final rinsing process can be increased compared to the case of the standard course. Thereby, in a final rinse process, many finishing agents can be made to osmose | permeate a laundry, As a result, the scent effect of a finishing agent can be exhibited more highly.

The washing / drying machine 10 includes a warm air supply device 50 as a heating means for heating the laundry in the rotating tub 18 before the final rinsing process (step S4X3) in the scenting course. That is, when the scenting course is selected, the control device 16 executes the hot air supply step (step S4X2) and drives the hot air supply device 50 before executing the final rinsing step (step S4X3). . Thereby, warm air is supplied into the rotating tub 18 and the laundry in the rotating tub 18 is heated. According to this, the chemical reaction of the finishing agent in the final rinsing process can be promoted by warming the laundry before the final rinsing process (step S4X3). As a result, the scent effect of the finishing agent can be exhibited more highly.

In this case, the washing / drying machine 10 may include hot water supply means for supplying hot water into the water tank 19 in the final rinsing step (step S4X3) instead of the hot air supply device 50. That is, you may perform a final rinse process (step S4X3) with warm water. According to this, the chemical reaction of the finishing agent in the final rinse process can be promoted by warming the laundry during the final rinse process (step S4X3). As a result, the scent effect of the finishing agent can be exhibited more highly.

The stirring time in the final rinsing process (steps S3X2, S4X3) is shorter in the scented specification (scented course) than in the standard specification (standard course). Moreover, the scenting specification (scenting course) is slower in the scenting specification (scenting course) than the standard specification (standard course) in the rinsing rotation speed of the rotary tank 18 in the final rinsing process (steps S3X2, S4X3). According to these, when the rinsing time of the final rinsing step is increased by executing the scenting course, it is possible to reduce the damage to the laundry due to stirring, and the effect of soaking is obtained. Furthermore, even if it is a case where the time of the last rinse process is lengthened by execution of a scenting course, the increase in the load of the motor 211 can be suppressed.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS.
In the first embodiment, the washing / drying machine 10 is provided with a “scenting” course that emphasizes scenting with a finishing agent as an automatic operation. According to this, the user can perform the washing operation in which the fragrance effect is emphasized by selecting the “scenting” course in the “washing” operation, for example. On the other hand, in the second embodiment, for example, the “scent level” is set for courses other than the “scenting” course such as the “careful” course and the “blanket” course, so that the scent effect by the finishing agent is more effectively achieved. Do the driving to make it work.

In the second embodiment, the washing / drying machine 10 has a fragrance level of 2 or more with respect to the fragrance specification. That is, as shown in FIG. 11, the washing / drying machine 10 has two levels of fragrance levels of “strong” and “weak” with respect to the scenting specifications. The scent level “strong” is a specification that makes the scent effect of the finish higher than the standard specification. The scent level “weak” has a higher scent effect than the standard specification, but the specification has a lower scent effect than the scent level “strong”.

As shown in FIG. 10, the operation panel 13 is provided with a “fragrance level” key 65. The user operates the “fragrance level” key 65 after selecting an arbitrary course such as a “standard” course, a “careful” course, or the like for automatic driving. Then, according to the number of operations of the “fragrance level” key 65, the “strong” display portion 661 and the “weak” display portion 662 which are display portions for displaying the fragrance level are switched on. When the “strong” display portion 661 is lit, the scent level “strong” is selected, and when the “weak” display portion 662 is lit, the scent level “weak” is selected. When neither the “strong” display portion 661 nor the “weak” display portion 662 is lit, the scent level is not selected. In this case, the “scent level” key 65 functions as a changing means for changing the “scent level” composed of two or more levels.

The user turns on the power of the washing / drying machine 10 (turns on the power), sets the automatic operation, the course, and the “fragrance level”, and then operates the “start” key 64. As shown in FIG. 12, when the “start” key 64 is operated, the control device 16 executes Steps S11 to S19 as in the first embodiment. Thereafter, the control device 16 determines whether or not the “scent level” is set in step S50. When the “scent level” is not set (NO in step S50), the control device 16 proceeds to step S51. And the control apparatus 16 performs each process about the course of the automatic driving | operation currently set with the standard specification shown in FIG. For example, when the currently set automatic driving and course are “standard” courses of “laundry” driving, the process content is the same as the “standard” courses shown in FIG. 8 of the first embodiment.

On the other hand, as shown in FIG. 12, when the control device 16 determines that the “fragrance level” is set in step S50 (YES), the control device 16 proceeds to step S52. And the control apparatus 16 performs each process shown in FIG. 13 based on the setting content of "strong" or "weak" of "scenting specification" shown in FIG.

Here, as shown in FIG. 11, the fragrance levels “strong” and “weak” are set for each of the set water levels “high”, “medium”, and “low” in the standard specification. However, the basic operation is the same regardless of whether the set water level is “high”, “medium”, or “low” and the scent level is “strong” or “weak”. Therefore, the description about the difference in each set water level is abbreviate | omitted. Moreover, while explaining each process in each fragrance level in parallel, when description is common in each fragrance level, step number S is shown in common like step S5XY1, for example. In this case, if the fragrance level is “strong”, Y = 1, and if the fragrance level is “weak”, Y = 2. Note that X = 1 when the set water level is “high”, X = 2 when “medium”, and X = 3 when “low”, as in the first embodiment. It is.

When the controller 16 determines that the scent level is “strong” in step S50, it executes steps S5X11 to S5X15, and if it determines that the scent level is “weak”, it executes steps S5X21 to S5X25.

In step S5XY1, the control device 16 performs the final pre-rinse dehydration step, similarly to step S4X1 shown in FIG. 9 of the first embodiment. In this final pre-rinse dehydration step, as shown in FIG. 11, the control device 16 uniformly rotates the rotary tank according to the “strong” and “weak” fragrance levels with respect to the set values at each set water level of the standard specification. The dehydration rotation speed of 18 is increased and the dehydration time is lengthened. In this case, the dehydration rotation speed is higher when the fragrance level is “strong” than when the fragrance level is “weak”. The dehydration time is longer when the fragrance level is “strong” than when the fragrance level is “weak”.

That is, in the dehydration process before the final rinse, the dehydration rotation speed is standard specification +100 [rpm] when the fragrance level is “strong” (step S5X11), and is standard when the fragrance level is “weak” (step S5X21). Specification +50 [rpm]. In the dehydration process before the final rinse, the dehydration time is standard specification + 2'00 "when the fragrance level is" strong "(step S5X11), and standard specification when the fragrance level is" weak "(step S5X21). + 1'00 ".

Next, in step S5XY2, the control device 16 executes a warm air supply process in the same manner as in step S4X2 shown in FIG. 9 of the first embodiment. In this hot air supply process, as shown in FIG. 11, the control device 16 uniformly supplies hot air according to the scent level “strong” and “weak” with respect to the set values at each set water level of the standard specification. Increase the operating time of the process. The operating time of this hot air supply process is standard specification + 10'00 "when the fragrance level is" strong "(step S5X12), and standard specification + 6'00 when the fragrance level is" weak "(step S5X22). In this case, since the hot air supply process is not executed in the standard specification, the standard specification = 0′00 ″.

Next, in step S5XY3, the control device 16 executes the final rinsing process, similarly to step S4X3 shown in FIG. 9 of the first embodiment. In this final rinsing step, as shown in FIG. 11, the control device 16 uniformly sets the rinsing water level and finish according to the fragrance level “strong” and “weak” with respect to the setting values at the standard setting water levels. Lower the agent input water level, increase the rinsing time, decrease the rinsing rotation speed, and shorten the stirring time. In this case, the rinsing water level and the finishing agent charging water level are lower when the fragrance level is “strong” than when the fragrance level is “weak”. The rinsing rotation speed is lower when the fragrance level is “strong” than when the fragrance level is “weak”. The stirring time is shorter when the fragrance level is “strong” than when the fragrance level is “weak”.

That is, in the final rinsing process, the rinsing water level is standard specification −7 [L] when the scent level is “strong” (step S5X13), and standard specification when the scent level is “weak” (step S5X23). 5 [L]. In the final rinsing process, the finishing agent input water level is standard specification −15 [L] when the fragrance level is “strong” (step S5X13), and is standard when the fragrance level is “weak” (step S5X23). The specification is -10 [L]. In the final rinsing process, the rinsing time is standard specification + 8'00 "when the fragrance level is" strong "(step S5X13), and standard specification +5 'when the fragrance level is" weak "(step S5X23). 00 ″.

In the final rinsing process, the rinsing rotation speed is standard specification -20 [rpm] when the fragrance level is “strong” (step S5X13), and standard specification when the fragrance level is “weak” (step S5X23). -10 [rpm]. In the final rinsing step, the stirring time is (standard specification −4 ″) / 1 ′ when the fragrance level is “strong” (step S5X13), and when the fragrance level is “weak” (step S5X23), (Standard specification-2 ″) / 1 ′.

Next, the control device 16 performs drainage in step S5XY4 as in step S4X4 shown in FIG. 9 of the first embodiment. Thereafter, in step S5XY5, the control device 16 executes a final dehydration step, similarly to step S4X5 shown in FIG. 9 of the first embodiment. In this final dehydration step, as shown in FIG. 11, the control device 16 uniformly sets the dehydration rotation speed according to the fragrance level “strong” and “weak” with respect to the set value at each set water level of the standard specification. Reduce the speed and reduce the dehydration time. In this case, the dehydration rotation speed is lower when the fragrance level is “strong” than when the fragrance level is “weak”. Further, the dehydration time is shorter when the fragrance level is “strong” than when the fragrance level is “weak”.

That is, in the final rinsing process, the dehydration rotation speed is standard specification −100 [rpm] when the fragrance level is “strong” (step S5X15), and standard specification when the fragrance level is “weak” (step S5X25). -50 [rpm]. The dehydration time is standard specification -2'30 "when the fragrance level is" strong "(step S5X15), and standard specification + 2'00" when the fragrance level is "weak" (step S5X25). .

According to this, the same effect as the first embodiment can be obtained. Further, the user can select a favorite scent level from a plurality of scent levels, in this case, two levels. Therefore, it is possible to give the laundry a scent that suits the user's preference. Further, for example, in a course other than the “scenting” course such as the “careful” course and the “blanket” course, it is possible to easily impart a scent to the laundry.

(Third embodiment)
Next, a third embodiment will be described with reference to FIGS.
In the first embodiment and the second embodiment, the washing / drying machine 10 includes the water supply input device 30 as the water supply means and the input means. On the other hand, in the third embodiment, the washing / drying machine 10 includes a water supply device 71 as a water supply device and a water supply device 72 as a water supply device instead of the water supply input device 30. Although not shown in detail in the water supply device 71, the water supply device 30 shown in FIG. 4 does not include the finishing agent storage unit 312 and the second water supply valve 35. Therefore, in 3rd Embodiment, the washing-drying machine 10 is not provided with the 2nd water supply valve 35, as shown in FIG.

The charging device 72 is detachably provided on the inner peripheral side surface of the rotating tub 18 as shown in FIG. The charging device 72 is for charging the finishing agent accommodated in the charging device 72 into the water tank 19 by the action of centrifugal force during dehydration. In this case, when the centrifugal force due to dehydration acts twice, the charging device 72 charges the finishing agent stored in the charging device 72 into the water tank 19.

Specifically, as shown in FIG. 16, the charging device 72 is configured in a flat container shape along the inner peripheral side surface of the rotating tub 18 as a whole. In this case, with respect to the paper surface of FIG. 16, the right front side is the rotation center direction of the rotary tank 18, and the left back side is the centrifugal direction of the rotary tank 18. The inside of the charging device 72 is partitioned into a first chamber 721, a second chamber 722, and a third chamber 723. The first chamber 721 is provided in the upper portion of the charging device 72 on the rotation center side. The second chamber 722 is located above the charging device 72 and is provided on the centrifugal side with respect to the first chamber 721. The third chamber 723 is adjacent to the first chamber 721 in the circumferential direction, and is provided on the center side with respect to the second chamber 722. The third chamber 723 is provided over the entire vertical direction of the charging device 72. That is, the bottom of the third chamber 723 is located lower than the bottoms of the first chamber 721 and the second chamber 722.

A communication portion 724 is formed in a wall portion that partitions the first chamber 721 and the second chamber 722. The first chamber 721 and the second chamber 722 are communicated with each other through the communication portion 724. Further, the second chamber 722 and the third chamber 723 are communicated with each other through a communication path 725. An inlet 726 is provided in the wall of the third chamber 723 in the centrifugal direction. The input port 726 is connected to the water tank 19.

The user inputs the finishing agent 90 into the first chamber 721 of the input device 72 as shown in FIG. Thereafter, for example, when the first dehydration process shown in step S17 of FIG. 7, that is, the first dehydration process in the operation, is performed, the finishing agent 90 accommodated in the first chamber 721 is shown in FIG. As described above, the communication portion 724 moves to the second chamber 722 by centrifugal force. Thereafter, when the first dehydration step is completed and the centrifugal force is released, the finishing agent in the second chamber 722 passes through the communication path 725 to the third chamber 723 as shown in FIG. Fall. Thereafter, for example, when the final pre-rinse dehydration step in step S3X1 in FIG. 8 or step S4X1 in FIG. 9, that is, the second dehydration step in the operation, is performed, the finishing agent accommodated in the third chamber 723 is As shown in (d) of FIG. 17, it is thrown into the water tank 19 from the inlet 726 by centrifugal force.

In this case, the control device 16 controls the timing of putting the finishing agent 90 into the water tank 19 by controlling the timing and number of times of executing the dehydration process.
According to this, the same effect as each said embodiment is acquired.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIGS.
In the fourth embodiment, the control device 16 executes the cleaning process after driving the scenting operation course or after driving each course with the scenting specification. That is, when the control device 16 operates the scenting operation course, as shown in FIG. 18, the control device 16 executes a cleaning process in step S23. In addition, when the control device 16 is operated with a scented specification for a certain driving course, for example, when the scent level is set for the “standard” course of the “laundry” driving, as shown in FIG. Perform the cleaning process.

In the cleaning process, the path through which the finishing agent passes in the rotary tank 18, the water tank 19, and the water supply input device 30, in this case, the finishing agent storage unit 312 and the water injection hose 32 shown in FIG. 4 are cleaned. That is, in the fourth embodiment, the washing / drying machine 10 includes an electronically controlled third water supply valve 81 and a water discharge nozzle 82 as shown in FIG. As shown in FIG. 21, the third water supply valve 81 is electrically connected to the control device 16, and is opened and closed under the control of the control device 16.

The 3rd water supply valve 81 is branched from the water supply hose connection part 33, as shown in FIG. The water discharge nozzle 82 is connected to the discharge side of the third water supply valve 81 and penetrates the water tank cover 192 from the upper part of the water tank 19 to the inside of the water tank 19. When the third water supply valve 81 is opened, water from the water source is discharged from the water discharge nozzle 82 to the inside of the water tank 19 through the water supply hose connection portion 33 and the third water supply valve 81. The water discharged from the water discharge nozzle 82 pours onto the outer surface of the rotating tank 18 or the inner surface of the water tank 19, and flows down to the bottom of the water tank 19 along the outer surface of the rotating tank 18 or the inner surface of the water tank 19.

Also, the washing / drying machine 10 is provided with a lid opening / closing sensor 83 as shown in FIG. The lid opening / closing sensor 83 is a limit switch, for example, and is electrically connected to the control device 16 as shown in FIG. The control device 16 determines whether the lid 14 is open or closed based on the detection result of the lid opening / closing sensor 83.

When the controller 16 executes the cleaning process in step S23 of FIG. 18 or step S53 of FIG. 19, the control device 16 executes the control contents shown in FIG. Then, in step S61, the control device 16 first determines whether or not the lid 14 has been opened / closed based on the detection result of the lid opening / closing sensor 83. That is, when the control device 16 detects that the lid 14 is opened and then closed after the washing operation is finished (YES in step S61), the user opens and closes the lid 14 to perform washing in the rotary tub 18. Judge that an object has been removed. On the other hand, when the opening / closing of the lid 14 is not detected (NO), the control device 16 repeats step S61 and waits until the opening / closing of the lid 14 is detected.

When the opening / closing of the lid 14 is detected (YES in step S61), the control device 16 proceeds to step S62 and determines whether or not the “start” key 64 has been operated. When the “start” key 64 is not operated (NO in step S62), the control device 16 repeats step S62 until the “start” key 64 is operated. On the other hand, when the control device 16 detects that the “start” key 64 is operated (YES in step S62), the control device 16 proceeds to step S63.

In step S63, the control device 16 opens the second water supply valve 35 and supplies water to the finishing agent storage unit 312 of the water supply input device 30. As a result, the interior of the finishing agent container 312 is cleaned. Further, the water supplied into the finishing agent storage unit 312 is supplied into the rotary tank 18 through the water injection hose 32. Thereby, the inside of the water injection hose 32 and the rotary tank 18 is washed. Further, the control device 16 opens the third water supply valve 81 and discharges water from the water discharge nozzle 82 in step S63. Thereby, the outer side of the rotating tank 18 and the inner side of the water tank 19 are washed. At this time, the control device 16 drives the motor 211 to rotate the rotating tank 18. Thereby, the water discharged from the water discharge nozzle 82 is poured evenly onto the outer peripheral surface of the rotating tub 18, and the outer peripheral surface of the rotating tub 18 can be washed more efficiently. The control device 16 may open the first water supply valve 34 and inject water into the rotary tank 18 through the detergent container 311 of the water supply input device 30, thereby cleaning the inside of the rotary tank 18. .

In this case, the first water supply valve 34 and the second water supply valve 35 function as first cleaning means for cleaning mainly the inside of the rotary tank 18, that is, a cleaning means. The second water supply valve functions as a second cleaning means, that is, a cleaning means, for cleaning the finishing agent storage portion 312 of the water supply input device 30 as the input means. The third water supply valve 81 and the water discharge nozzle 82 function as third cleaning means that cleans mainly the outer side of the rotary tank 18 and the inner side of the water tank 19, that is, a cleaning means.
