In addition, FIG. 8 illustrates the removal of the upstream air supply unit 51 and the downstream bellows. Individual of the hot air duct 26 behind the tube 27.

As shown in Figs. 9 (a) and (b), the hot air duct 26 includes a duct portion 26a having an air path inside, a connection opening 26b connected to the outlet of the air supply unit 51 (see Fig. 1), and A connection opening 26c to which the bellows tube 27 is connected. The connection opening 26b has a substantially oval shape (flat shape), and the connection opening 26c has a circular shape.

The hot air duct 26 is formed so that the connection portion 26d connected to the second high-concentration lotion liquid supply means 54 supply pipe 54b and the connection portion 26e connected to the water supply pipe 55a of the tap water supply means 55 protrude near each other. . The connection portion 26d and the connection portion 26e are in the shape of tubes that protrude toward the side, and are arranged parallel to each other. As described above, by protruding the connecting portions 26d and 26e toward the side (left direction), it is possible to prevent the air path of the drying filter unit 56 located above from being obstructed.

As shown in FIG. 9 (c), nozzles 26d1, 26e1 protruding toward the inside of the flow path Q in the duct portion 26a are formed at the tip ends of the connection portions 26d, 26e. A supply port 26d2 for discharging a high-concentration lotion liquid is formed on the peripheral surface (side surface) of the tip of the nozzle 26d1.

The opening area of the supply port 26d2 is formed larger than the opening area of the supply port 26e2, in other words, the supply amount of the high-concentration lotion liquid becomes larger than the supply amount of the tap water.

As shown in FIG. 9 (d), the nozzle 26e1 is positioned on the upstream side of the flow of wind more than the nozzle 26d1. That is, the supply port 26e2 of the tap water is located more upstream than the supply port 26d2 of the high-concentration lotion liquid. The supply ports 26d2 and 26e2 are directed downstream of the flow of wind. That is, the supply ports 26d1 and 26e1 are oriented substantially opposite to the side to which the wind (air) from the air supply unit 51 is supplied. Thereby, the supply of high-concentration lotion liquid from the supply port 26d2 can be prevented from being blocked by the pressure of the wind, and the supply of tap water from the supply port 26e2 can be prevented from being blocked by the pressure of the wind.

Fig. 10 is a sectional view taken along the line A-A in Fig. 8.

As shown in FIG. 10, when the air supply unit 51 is driven, the fan impeller 24b is rotated by the motor 24a to generate high-speed wind. High-speed wind is blown out from the air outlet 52 through the hot air duct 26, the bellows tube 27, and the bellows tube joint 28. When the air supply unit 51 and the second circulation pump 54a (see FIG. 2) are driven simultaneously, the high-concentration lotion liquid generated at the bottom of the outer tank 2 is passed through the supply pipe 54b (see FIGS. 2 and 5). It is pumped up and supplied from the supply port 26d2 to the flow path Q in the hot air duct 26. The high-concentration lotion liquid supplied from the supply port 26d2 comes into contact with the high-speed wind supplied from the air supply unit 51, thereby spraying the high-concentration lotion liquid. The sprayed high-concentration lotion liquid passes through the hot air duct 26, the bellows tube 27, and the bellows tube joint 28, and is blown out from the blowout port 52 into the rotary drum 3.

Then, the high-speed wind is diffused into the rotating drum 3 and adheres to the laundry, so that the high-concentration lotion liquid can permeate the laundry substantially uniformly. In order to spray the high-concentration lotion liquid efficiently and uniformly throughout the laundry, it is better to set it according to the air volume and wind speed. For example, when the air volume is 1.5 m ³ per minute and the wind speed is 100 m / s, it is preferably about 0.05 to 3.0 L / min.

When the supply of the high-concentration lotion liquid from the supply port 26d2 is completed, the second circulation pump 54a is stopped. Then, when the spray water supply solenoid valve 11e is opened, the tap water flows through the water supply pipe 55a (see FIG. 7) and is supplied from the supply port 26e2. The tap water supplied from the supply port 26e2 comes into contact with the high-speed wind supplied from the air supply unit 51, thereby spraying the tap water. The sprayed tap water passes through the hot air duct 26, the bellows pipe 27, and the bellows joint 28 to clean the high-concentration lotion liquid adhering to the wall surface of the flow path Q up to the air outlet 52. At this time, since the supply port 26e2 of the tap water is located more upstream than the supply port 26d2 of the high-concentration lotion liquid, the entire flow path to which the high-concentration lotion liquid is adhered can be cleaned.

Fig. 11 is a bottom view showing a modification of the hot air duct.

As shown in FIG. 11, the hot air duct 26A is provided with: a confluence part 26h, which converges: a connection part 26f connected to a supply pipe 54b (refer to FIGS. 2 and 7) for supplying a high-concentration detergent, and supply tap water The connection portion 26g to which the water supply pipe 55a (see FIG. 7) is connected. The merging portion 26h is formed as a nozzle 26i composed of one flow path, and the nozzle 26i is configured to protrude into the flow path Q of the duct portion 26a. A supply port 26i1 is formed on a peripheral surface (side surface) of the front end of the nozzle 26i. In addition, the supply port 26i1 is formed downstream of the flow toward the wind to prevent the supply of the high-concentration lotion liquid or the tap water by the pressure of the wind.

As described above, by constituting the nozzle 26i in which the high-concentration lotion liquid is in common with the tap water, the obstruction to the flow of wind can be reduced more than when the nozzles are separately provided. In addition, the common nozzle 26i is used in After the high-concentration lotion liquid is supplied, tap water is supplied to wash the high-concentration lotion liquid attached to the tip of the nozzle 26g, and the high-concentration lotion liquid is prevented from flowing down from the front end of the nozzle 26i after the high-concentration lotion liquid is supplied. .

In addition, the supply pipe 54b of the second high-concentration lotion liquid supply means 54 (high-concentration lotion liquid supply means) and the supply pipe 55a of the tap water supply means 55 are connected to the hot air duct phase fixed to the housing 1 side. Compared with the provision of the movable portion in the supply pipes 54b and 55a, it is possible to improve the assemblability and reduce the wear during operation, which is also beneficial to the quality.

The user will pull out the lotion pan 7 and put the powder lotion displayed on the display 14 toward the lotion pan 7. The control device 60 opens the main water supply solenoid valve 11b of the water supply solenoid valve 11 after the time (for example, 1 minute) required by the standby user to put the lotion into the lotion tray 7, and then faces the lotion tray 7 Supply. The powder lotion passes through the bellows hose 17 together with the water supplied, and then flows down from the water supply port 2a of the outer tank 2 to the recessed portion 2f of the outer tank 2.

In addition, since water from the water supply port 2a flows along the inner peripheral surface of the outer tank 2, no water or lotion flows into the rotary drum 3. Accordingly, it is possible to prevent discoloration or color unevenness caused by the undissolved powder lotion coming into direct contact with the laundry.

When the lotion is a liquid lotion, in order to prevent the high-concentration liquid lotion from flowing into the tank 2 before the main water supply solenoid valve 11b is opened, a liquid lotion room is provided on the lotion tray 7. It is temporarily stored here in advance, and is then supplied to the outer tank 2 while being diluted by the water supply from the main water supply solenoid valve 11b.

Then, the control device 60 stops the water supply after the water supply reaches the lotion-dissolved water level. The water supply amount is controlled in accordance with the washing amount (cloth amount), for example, it is set to be lower than the water level in the washing step. The water supply amount is controlled by the water level sensor 34. This amount of water is, for example, set the lotion concentration to the maximum It is 10 times larger and formed. Here, the lotion concentration is defined as the standard concentration specified by the lotion manufacturer (in general powder synthetic lotions, the concentration when 20 g of the lotion is dissolved in 30 liters of water) is doubled.

After that, the control device 60 energizes the circulation pump motor 47 to reversely rotate the first circulation pump 53a and execute the dissolution of the lotion. The water and lotion stored in the bottom of the outer tank 2 and the recessed portion 2f will pass from the drainage port 21 through the bellows hose 22, the filter box 23, and then enter the casing 42 through the suction port. Then, it is discharged from the discharge port 45, and then circulates through the bellows hose 40 from the inflow port 18 to the recessed portion 2f. The lotion is agitated by the blades of the flow path of the first circulation pump 53a to continue the dissolution to generate a high-concentration lotion solution. The time for dissolving the lotion is set to, for example, 10 seconds.

In step S150, the control device 60 performs spraying and dispersing of the high-concentration lotion liquid. (First cycle step). That is, the control device 60 causes the first circulation pump 53a to rotate forward, so that the high-concentration lotion liquid stored in the bottom of the outer tank 2 and the recessed portion 2f passes from the drain port 21 through the bellows hose 22 and the filter box 23, and then It enters the housing 42 through the suction port. Then, it is discharged from the discharge port 44 and is supplied from the nozzle 53c into the rotary drum 3 through the bellows hose 53b1 and the circulation flow path 53b2. For example, when 10 liters of a high-concentration lotion is generated, 7 liters of 10 liters are supplied for a predetermined time (for example, 2 to 3 seconds).

In step S160, the control device 60 executes spray dispersion of the high-concentration lotion liquid (second cycle step). That is, the control device 60 drives the second circulation pump 54a to pass the high-concentration lotion liquid stored in the bottom of the outer tank 2 and the recessed portion 2f through the supply pipe 54b to the blowout port. The hot air duct 26 on the upstream side of 52. At this time, hot air is supplied to the hot air duct 26 by energizing the air supply unit 51 (the fan motor 24a and the heater 51b), and the hot air from the air supply unit 51 and the high-concentration lotion liquid supplied from the supply port 26e1 are supplied. Contact, thereby spraying a high concentration lotion. For example, when 10 liters of a high-concentration lotion is produced, the remaining 3 liters are supplied in a spray form.

As described above, the high-concentration lotion liquid is atomized by hot air, and the spray of the high-concentration lotion liquid with a relatively high temperature is sprayed on the laundry, thereby improving the detergency of the laundry. In addition, by using hot air, the lotion can be effectively mixed with tap water. In addition, the hot air is not necessarily limited, and when the heater 51b is turned off, it may be sprayed by contacting the unheated air.

In step S170, the control device 60 supplies water into the outer tank 2 and cleans the lotion flow path. That is, the control device 60 opens the main water supply solenoid valve 11b to supply water to the water level required for the cleaning step. In addition, the control device 60 simultaneously opens the spray water supply solenoid valve 11e and supplies it from the supply port 26e2 of the nozzle 26e1 formed in the hot air duct 26 via the supply pipe 54b. Then, the control device 60 drives the air blowing unit 51 to supply the heated high-speed wind (hot air) to the rotary drum 3 through the hot air duct 26, the bellows tube 27, and the bellows tube joint 28 from the air outlet 52. Thereby, the tap water is sprayed by colliding the tap water with a high-speed wind (hot air).

The sprayed tap water has an effect on the inner wall surface of the hot air duct 26, the inner wall surface of the bellows tube 27, and the inner wall surface of the bellows tube joint 28. After the lotion liquid is washed, it is discharged from the air outlet 52. This makes it possible to prevent the lotion from adhering to the lotion flow path (air path) even if the drying step is performed after the washing step (washing, rinsing, and dehydration) is performed by spraying a high-concentration lotion liquid from the blowing port 52 in a spray form. ), And mold and the like are generated in accordance with this situation, and the air passage can be maintained in a clean and hygienic state.

In addition, in the washing and drying machine S, the supply port 26e1 of the tap water is provided on the upstream side of the flow of the wind than the supply port 26e1 of the high-concentration lotion solution (spray). The entire wall of the air path is cleaned.

As described above, cleaning the lotion flow path (air path) by spraying the tap water with hot air can improve the cleaning power of the lotion to remove dirt. In addition, it is not necessarily limited to hot air, and spraying may be performed by contacting the unheated air while the heater 51b is OFF.

Moreover, in the case of washing the lotion liquid with tap water, there is no limitation to a structure in which the tap water is sprayed for cleaning, and a structure in which the tap water is sprayed and supplied may be combined with no tap water (the air supply unit 51 is OFF) ) Is a structure that uses liquid supply. For example, the wall surface of the lotion flow path (air path) may be rinsed by first supplying tap water after spraying and then supplying tap water in liquid form.

In step S180, the control device 60 performs a washing step. This washing step is performed in advance. By rotating the rotating drum 3 forward and reverse (from 35 to 45 revolutions per minute), the circulation pump motor 47 is energized, the first circulation pump 53a is rotated forward, and the outer tank is rotated. The washing water at the bottom of 2 is sprayed onto the laundry from the nozzle 53c. Use settings in rotation The lifter 3b on the inner peripheral wall surface of the drum 3 repeats the movement of lifting and lowering the laundry. The rotation of the rotary drum 3 and the operation of the first circulation pump 53a are intermittently performed. During the stop period of the rotary drum 3 and the first circulation pump 53a, the water supply solenoid valve 11 is opened while referring to the detection signal of the water level sensor 34. Make up the water so that the water level does not exceed the set water level. By repeating this operation several times, the washing water is uniformly immersed in the laundry.

When the forward and reverse rotation of the rotating drum 3 is performed for the first time, washing water having a detergent concentration of about 10 times is sprinkled on the laundry and penetrates into the laundry. Since the high-concentration washing water spreads while being diffused in a thin film form from the nozzle 53c, the washing product is uniformly penetrated by the penetration effect of the lotion. In the case where there is a lot of laundry, although the washing water from the nozzle 53c spreads the laundry near the outer periphery of the rotating drum 3, the rotating drum 3 is rotated by the distribution of the high-concentration lotion liquid in step S180. Since the washing water is permeated into the laundry from the outer peripheral side of the rotating drum 3, the entire washing is permeated with the washing water. In addition, since a lot of cells are contained in high-concentration washing water saturated with the laundry, the effect of dissolving oil stains to make the dirt float from the laundry is very large, and a high washing power can be obtained.

In addition, by increasing or decreasing the rotation speed of the first circulation pump 53a to change the flow rate, the reach distance of the spray can be changed, and the laundry can be evenly dispersed. That is, when the rotation speed is reduced to reduce the flow rate, the spray can be spread to the laundry located on the front side of the rotary drum 3, and when the rotation speed is increased to increase the flow rate, the spray can be spread. The laundry in place on the deep side of the rotating drum 3.

In addition, the control device 60 performs a formal washing in the washing step. That is, while rotating the rotary drum 3 in the forward and reverse direction (from 35 to 45 revolutions per minute), the first circulation pump 53a is rotated in the forward direction to spray the washing water stored in the bottom of the outer tank 2 from the nozzle 53c to the laundry. . Finally, the operation of the first circulation pump 53a is stopped to stop the circulation of the washing water, and the operation of unloading the laundry while rotating the rotary drum 3 in a forward and reverse direction in a short period is performed, and then the formal laundry ends.

In step S190, the control device 60 executes drainage and dehydration steps. First, the drain valve 25 is opened to drain the water in the outer tank 2. After the completion of the drainage is detected by the water level sensor 34, the rotary drum 3 is rotated in one direction to perform centrifugal dehydration of the washing water contained in the laundry.

In step S200, the control device 60 opens the main water supply solenoid valve 11b, and supplies water from the water supply port 2a to the bottom of the outer tank 2 until the set water level is reached.

In step S210, the control device 60 performs a flushing step. In the same way as a formal laundry, while rotating the rotary drum 3 forward and reverse (from 35 to 45 revolutions per minute), the first circulation pump 53a is rotated forward to remove the flushing water stored in the bottom of the outer tank 2 from the nozzle 53c. The cycle is performed by spraying onto the laundry to perform rinsing.

Then, in a state where the rotation of the rotary drum 3 is stopped and the operation of the first circulation pump 53a is stopped, the water level sensor 34 is used to detect the water level of the flushing water stored in the bottom of the outer tank 2 while making up water so that The water level will not exceed the set water level. Since the washing water flowing out of the nozzle 53c is formed into a thin film and spread to the laundry, the washing water can be evenly sprinkled on the laundry to effectively dilute the lotion components contained in the laundry, and the washing performance can be improved. After that, in a state where the first circulation pump 53a is stopped to stop the circulation of the flushing water, the rotary drum 3 is rotated forward and reverse in a short period to perform the unraveling operation.

Then, perform the second water flushing. This second water storage rinse is performed by supplying water to the softening treatment agent input chamber of the lotion tray 7 by opening the treatment agent water supply solenoid valve 11c, and introducing the softening treatment agent into the room. Control of the bottom of slot 2. The other operations are performed in the same manner as in the first water storage flush.

In step S220, the control device 60 performs a drainage and dehydration step (final dehydration). In the final dehydration, the drum motor 4 is operated to rotate the rotary drum 3 at a high speed in one direction while the drain valve 25 is kept open, and the laundry in the rotary drum 3 is centrifuged and dewatered. The final dehydration operation time is set to a time at which a desired dehydration rate can be obtained.

In step S230, the control device 60 determines whether the washing and drying program is set. When the washing and drying program is set (Yes), it proceeds to step S240. When the washing and drying program is not set (No), it will End processing.

When the washing and drying program is set, the control device 60 executes a drying step in step S240. In this drying step, the rotary drum is rotated while the drain valve 25 is maintained, as in the washing step. 3 While performing forward and reverse rotation, the air supply unit 51 provided in the middle of the drying duct 29 is operated to suck out the air in the outer tank 2 into the drying duct 29, and when passing through the drying duct 29, make it It comes into contact with cooling water (supply by opening the cooling water supply solenoid valve 11d to supply the cooling water) flowing from a water-cooled dehumidification mechanism provided in the drying duct 29. After cooling and dehumidifying, the fluff filter 8 (refer to the (Fig. 7) The lint is collected, and air (wind) is heated by the heater 51b, and then blown into the rotary drum 3 from the hot air blowing port 52. The drying step is completed by a temperature sensor while monitoring the temperature of the hot air, and when the temperature change ratio is formed to a predetermined value.

However, in the washing and drying machine provided with only the first high-concentration lotion liquid supply means 53 (for spraying and dispersing the high-concentration lotion liquid), in order to improve the cleaning power, the washing machine moves from the first circulation pump 53a to the rotating drum 3 The path up to this point is relatively thick, and it is not possible to spread the high-concentration lotion liquid for a long time, which will cause the high-concentration lotion liquid to not penetrate into the entire laundry. In addition, since a high-concentration lotion liquid remains on the path from the first circulation pump 53a to the spray outlet (nozzle 53c), it is not possible to use all of the generated high-concentration lotion liquid. In addition, in a washer-dryer equipped with only the second high-concentration lotion liquid supply means 54 (a person spraying the high-concentration lotion liquid is sprayed), when the circulation flow rate is small, the blow-drying is completed until the laundry It takes longer. In contrast, when the circulation flow rate is increased in order to shorten the operation time, it becomes difficult to spray the lotion liquid when it comes into contact with the wind. Here, the washing and drying machine S has a structure including a circulation step in which a high-concentration lotion liquid is supplied into the rotary drum 3 by the first high-concentration lotion liquid supply means 53. The first cycle step (S150), and while supplying high-speed air from the air supply unit 51 to the air outlet 52, the second high-concentration liquid detergent supply means 54 supplies the high-concentration liquid detergent to the upstream side of the air outlet 52 The second cycle step (S160). Since the second high-concentration lotion liquid supply means can permeate the high-concentration lotion liquid throughout the laundry, the cleaning power can be improved, and the first high-concentration lotion liquid supply means and the second high-concentration lotion can be used together. The lotion liquid supply means can shorten the running time.

In the washing and drying machine S, the control device 60 performs control so that the first cycle step is executed before the second cycle step. This can further shorten the operation time. That is, when the second cycle step is performed first, the amount of the high-concentration lotion solution stored in the bottom of the outer tank 2 when the first cycle step is performed is smaller than that in the case where the first cycle step is performed first, The amount of pumping up of the first circulation pump 53a increases, and it takes more time to spread the lotion liquid.

In addition, in the washing and drying machine S, the first circulation step is configured such that the supply amount of the high-concentration lotion liquid per unit time becomes larger than that of the second circulation step. Therefore, when the second cycle step is performed after the first cycle step, a high-concentration lotion liquid that cannot be pumped in the first cycle step can be pumped up, and a smaller amount of high-concentration lotion liquid can be used for penetration. To the entire laundry.

Fig. 14 is a flowchart showing other operations of the washing and drying machine disclosed in the present invention. It should be noted that the same processes as those in the flowchart of FIG. 13 are given the same step numbers and repeated explanations are omitted.

As shown in FIG. 14, the control device 60 starts using the first After the circulation step (S150) performs the dispersion process of the high-concentration lotion liquid, it proceeds to step S151 to determine whether the water level of the outer tank 2 is below the first predetermined water level. That is, even if the first circulation pump 53a is rotated, the high-concentration lotion liquid in the piping amount from the first circulation pump 53a to the nozzle 53c will remain. When the lotion liquid is hardly drawn out into the rotary drum 3, Causes air and lotion liquid to mix and cause air locks to form foam. The first predetermined water level is set to a water level for preventing the air lock.

In step S151, the control device 60 determines whether the water level of the outer tank 2 is below the first predetermined water level, and when it is determined that it is not below the first predetermined water level (No), it repeats the processing of step S151, and when it is determined that it is at the first level When the water level is below the predetermined level (Yes), the process proceeds to step S160 to perform spray distribution of the high-concentration lotion.

In step S161, the control device 60 determines whether the water level of the outer tank 2 is above the second predetermined water level. The second predetermined water level is set higher than the first predetermined water level, and is set lower than the water level (water level when the lotion is dissolved) in the high-concentration lotion liquid generation step. In step S161, when the control device 60 determines that the water level of the outer tank 2 is not above the second predetermined water level (No), it proceeds to step S162, and when it is determined that it is above the second predetermined water level (Yes), it proceeds to step S163 proceeds.

In step S162, the control device 60 determines whether a predetermined time has elapsed. When it is determined that the predetermined time has elapsed (Yes), it proceeds to step S170, and when it is determined that the predetermined time has not elapsed (No), it returns to step S161. The predetermined time is set based on a previous test or the like.

For example, when the circulation of the high-concentration lotion liquid is repeated in the second cycle step, the phenomenon that the water level slowly rises by leaching the lotion liquid from the laundry occurs. In the case of artificial fibers, the above-mentioned phenomenon is unlikely to occur due to the low water content. However, fibers such as bath towels may leach water and may leach more than the water discharged from the second circulation pump 54a.

In step S163, the control device 60 performs spraying and dispersing of the high-concentration lotion. (First cycle step).

In step S164, the control device 60 determines whether the spray dispersion of the high-concentration lotion has passed a predetermined time. In addition, the predetermined time is determined based on prior experiments and the like. When the control device 60 determines that the predetermined time has not elapsed (S160, No), it repeats the processing of step S163, and when it is determined that the predetermined time has elapsed (S164, Yes), it proceeds to step S170.

In the above-mentioned washing and drying machine S, the control device 60 performs control so that when the water level in the outer tub 2 is determined to be lower than the first predetermined water level in the first cycle step (S150) (S151, Yes), The process proceeds to the second cycle step (S160). Thereby, as described above, air lock is prevented, and foaming of a high-concentration lotion liquid can be prevented.

Further, in the washing and drying machine S, the control device 60 performs control such that when the water level of the outer tub 2 is determined to be a second predetermined water level higher than the first predetermined water level in the second cycle step (S160), The process proceeds to the first loop step (S163). Thereby, before the washing step, a high-concentration lotion liquid can be sufficiently sprayed on the laundry, and the detergency of the laundry can be improved.

Fig. 15 is a view showing a washing and drying machine disclosed in the present invention; Flow chart of other actions.

The embodiment shown in FIG. 15 has a structure in which steps S155 and S160 are replaced by step S155.

In step S155, the control device 60 simultaneously performs spraying and dispersing of the high-concentration lotion (first cycle step) and spraying and dispersing of the high-concentration lotion (second cycle step). That is, the control device 60 drives the first circulation pump 53a and the second circulation pump 54a at the same time, disperses the spray-shaped high-concentration lotion liquid to the laundry from the nozzle 53c, and sprays the spray-shaped The high-concentration lotion is spread to the laundry.

As described above, by performing the first cycle step and the second cycle step at the same time in the washing and drying machine S, the operation time can be shortened compared with the case where the first cycle step is performed before the second cycle step.

In addition, this invention is not limited to the said embodiment, As long as it is a range which does not deviate from the meaning of this invention, it can change suitably. For example, although the drum-type washer-dryer S is described as an example in the foregoing embodiment, the present invention can also be applied to a vertical washer-dryer. In addition, although a washing and drying machine having a drying function is described, it can also be applied to a drum type washing machine having no drying function.

In addition, although a description is given of a case where the high-concentration lotion liquid generating means is made by stirring the tap water and the lotion at the bottom of the outer tank 2, it is not limited to the above structure, and may be generated in the lotion pan 7. The structure of the high-concentration lotion liquid can be appropriately changed.

In addition, when the spray distribution of the high-concentration lotion liquid is performed (S160), the tap water may be simultaneously supplied by the tap water supply means 55. borrow This makes it possible to adjust the concentration of the high-concentration lotion liquid, to make the concentration of the lotion liquid lighter, and to shorten the time of immersion into the laundry.
