As a result, the insect repellent treatment operation is started.

Referring to FIG. 4, when the insect repellent treatment operation is started, control unit 401 first executes a preparation step (S1).

In the preparation step, the control unit 401 operates the drive motor 30 to rotate the drum 23 at a rotation speed at which the centrifugal force acting on the clothes in the drum 23 is smaller than the gravity, and also rotates the blower fan 320. The drum 23 may rotate only in one direction, or may rotate in the forward and reverse directions.

The rotation of the drum 23 causes the clothing to tumble within the drum 23. The impact when the clothes fall to the bottom of the drum 23 removes lint and dust attached to the surface of the clothes. If clothing has clothing pests on it, the clothing pests can also be removed.

As the blower fan 320 rotates, air, that is, wind, circulates between the outer tank 20 and the circulation path 310. Foreign matter such as dust removed from the clothes floats in the air and is discharged into the outer tank 20 from the dehydration hole 23b of the drum 23 on the flow of circulating wind, and introduced into the circulation path 310 from the exhaust port 20c. be done. Foreign matter introduced into the circulation path 310 is collected by the dry filter 350.

The control unit 401 stops the drum 23 and the blower fan 320 after a predetermined period of time has elapsed. This completes the preparation process.

Next, the control unit 401 executes an insect repellent liquid generation step (S2).

In the insect repellent liquid generation step, the control unit 401 opens the second valve 112 of the water supply valve 110. As shown in FIG. 5(b), water is supplied into the insect repellent dispenser 210 via the second water supply hose 130. The insect repellent in the insect repellent dispenser 210 is washed away by the supplied water, is discharged from the insect repellent dispenser 210, and flows into the liquid storage tank 220 together with the water. As a result, the insect repellent liquid generated by mixing the insect repellent and water is stored in the liquid storage tank 220.

When a predetermined water supply time has elapsed from the opening of the second valve 112 and a predetermined amount of insect repellent liquid is stored in the liquid storage tank 220, the control unit 401 closes the second valve 112. This completes the insect repellent liquid generation step.

Note that the control unit 401 may execute the insect repellent liquid generation process in parallel with the preparation process. In this case, the time required for the insect repellent treatment operation can be shortened.

Next, the control unit 401 executes an insect repellent treatment process (S3).

In the insect repellent treatment process, the control unit 401 operates the pump 232 of the spray mechanism 230. As shown in FIG. 5(c), the operation of the pump 232 sends the insect repellent liquid in the storage tank 220 to the spray nozzle 231, where it is sprayed toward the clothing in the drum 23. As a result, the insect repellent component of the insect repellent adheres to the surface of the clothing.

Further, in the insect repellent treatment process, the control unit 401 operates the drive motor 30 to rotate the drum 23 at a rotation speed such that the centrifugal force acting on the clothing in the drum 23 is smaller than the gravity. This causes the clothing to tumble within the drum 23, making it easier for the sprayed insect repellent liquid to evenly cover the surface of the clothing, making it easier for the insect repellent component to adhere to the entire surface of the clothing.

The control unit 401 stops the pump 232 and the drum 23 when a predetermined spraying time has elapsed. This completes the insect repellent treatment process.

Next, the control unit 401 causes the display unit 404 and a speaker (not shown) to issue a notification urging the user to take out the clothes from the drum 23 (S4). Then, the control unit 401 monitors whether or not clothes have been taken out from inside the drum 23 (S5). When the clothes are removed from the drum 23, the door 12 is opened. Therefore, when the door sensor 406 detects the opening of the door 12 and then the closing of the door 12, the control unit 401 determines that the clothes have been taken out.

The control unit 401 rotates the drum 23, detects the load amount of laundry in the drum 23 by the load applied to the drive motor 30, and determines that the clothes have been taken out when the load amount is not detected. You may also do so.

When the control unit 401 determines that the clothes have been taken out (S5: YES), it executes a cleaning process (S6).

In the cleaning process, the control unit 401 opens the first valve 111 of the water supply valve 110 and supplies water into the outer tank 20 to a level at which the bottom of the drum 23 is immersed in water. Then, the control unit 401 rotates the drum 23 for a predetermined cleaning time. The drum 23 is cleaned by the water in the outer tank 20, and the insect repellent component of the insect repellent adhering to the inner peripheral surface of the drum 23 is removed.

Next, the control unit 401 opens the drain valve 41 to drain water from the outer tank 20. Thereafter, the control unit 401 rotates the drum 23 at a higher speed than the cleaning described above, and dehydrates the drum 23 for a predetermined dehydration time. Once the dehydration is complete, the cleaning process ends.

In this way, the insect repellent treatment operation is completed.

FIG. 6 is a flowchart showing the control operation of the control unit 401 executed in the washing/drying operation to which insect repellent processing is added.

When performing a washing/drying operation to which insect repellent treatment has been added, the user puts the clothes into the drum 23 and also puts the insect repellent into the insect repellent dispenser 210. Then, the user selects the insect-proof washing/drying course using the course selection button on the operation unit 403, and presses the start button. Thereby, the washing/drying operation is started.

Referring to FIG. 6, control unit 401 sequentially executes a washing process, an intermediate dehydration process, a rinsing process, a final dehydration process, and a drying process (S11 to S15).

Next, the control unit 401 executes a blowing process (S16).

In the blowing process, the control unit 401 rotates the blowing fan 320 without operating the second heat exchanger 340. Further, the control unit 401 rotates the drum 23 so that the clothing tumbles. Cold air is introduced into the outer tank 20, that is, into the drum 23, and the inside of the drum 23 and the clothes are cooled.

The control unit 401 stops the blower fan 320 and the drum 23 when the temperature inside the outer tank 20 detected by the temperature sensor 407 drops to a predetermined temperature, for example, 40°C. This completes the blowing process.

Next, the control unit 401 executes an insect repellent liquid generation step and an insect repellent treatment step (S17, S18). As a result, the clothes in the drum 23 are treated with insect repellent, and the insect repellent component adheres to the clothes. At this time, since the temperature inside the drum 23 and the clothing are low, the insect repellent component is less susceptible to the effects of heat.

Thereafter, when the clothes are taken out from the drum 23 based on the notification prompting to take out the clothes (S19, S20: YES), the control unit 401 executes a cleaning process (S21). As a result, the drum 23 is cleaned.

In this way, when the cleaning process is completed, the washing/drying operation ends.

Note that the control unit 401 may execute the insect repellent liquid generation process in parallel with the blowing process. In this case, the time required for washing and drying operation can be shortened.

When the user selects the insect repellent drying course and executes the drying operation with insect repellent treatment added, the control unit 401 controls the drying process in step S15 to the cleaning process in step S21 in the washing and drying operation shown in FIG. executed.

In addition, in the drum-type washing machine 1 of this embodiment, the drying device 60 may be equipped with an automatic cleaning device that automatically cleans the drying filter 350. In this case, the dry filter 350 is preferably arranged vertically. The automatic cleaning device includes, for example, a wiper mechanism having a wiper that rubs the capture surface of the dry filter 350, and a water supply mechanism that causes water to flow onto the capture surface of the dry filter 350. By rubbing the capture surface of the dry filter 350 with a wiper or by flowing water onto the capture surface, foreign matter such as dust attached to the capture surface is removed. For example, after a washing/drying operation or an insect repellent treatment operation is completed, a filter cleaning operation in which an automatic cleaning device is operated can be performed.
