  Cleaning of the dry air passage 10 using the cleaning tool is performed according to the implementation contents (1) to (3) below.

(1) Imaging of contamination state before cleaning and storage of imaging information Since the inside of the drying air passage 5 cannot be directly seen unless disassembled, the camera head of the flexible scope 24 is placed inside the drying air passage 5 before cleaning is started. 25 is inserted and the pollution situation in an air path is imaged. The imaging information before the start of cleaning is stored in the storage area of the liquid crystal monitor 27 so as to be reproducible.

  FIG. 6 is a diagram for explaining the imaging work before the start of cleaning. FIG. 7 is a diagram showing an insertion state of the camera head 25 by the imaging operation of FIG.

  FIG. 6 shows a state where the drying filter 10 at the top of the housing 2 is removed. The recess 40 that appears when the drying filter 10 is removed includes a suction-side surface 42 that is in contact with the suction passage 16 and is fitted with a mesh, and an opening 41 that communicates with the inside of the air passage on the opposite side of the suction passage 16. It is. The opening 41 is provided with a frame member 46 in which eight penetrating portions 41a are formed by three vertical partition pieces and one horizontal partition piece. The frame member 46 is formed of a thin piece that can ensure a wide ventilation area of the opening 41.

  When imaging, the inside of the dry air path 5 can be imaged by inserting the camera head 25 from the penetration part 41a. The flexible scope 24 is set in the imaging mode, and the camera head 25 is entered into the air path by finger operation, and as shown in FIG. 7, the contaminants such as the lint 43 remaining in the dry air path 5 are imaged. Stores and stores imaging information related to the contamination status before cleaning.

(2) Execution of Cleaning Operation for Dry Air Path 5 FIG. 8 shows a lint cleaning operation state in the vicinity of the opening 41 by the pickup tool 29.

  The cleaning operation of the drying air path 5 is performed as one set of lint grip cleaning by the pick-up tool 29, suction cleaning by a suction cleaner, and cleaning cleaning by a cleaning device. When the suction cleaning is performed first, the gap suction nozzle 38 may suck a large amount of lint and become clogged. Therefore, the lint cleaning by the pickup tool 29 is performed first.

  The lint grip cleaning operation by the pick-up tool 29 is performed by inserting the pick-up part 30 through the penetration part 41a of the opening part 41, pushing it into the deep part of the drying air passage 5, and grasping the lint 43 so that the lint 43 is not pushed in. Is called. As shown in FIG. 8, a collecting operation is performed in which the lint 43 is grasped and pulled out to the vicinity of the opening 41 and collected outside the opening 41 while being illuminated by the LED light 47.

  When the lint grip cleaning by the pick-up tool 29 is completed, suction cleaning is then performed by a suction cleaner. In the suction cleaning, like the lint cleaning by the pick-up tool 29, the gap suction nozzle 38 is inserted from the through portion 41a of the opening 41 to enter the deep portion of the drying air passage 5 and from the deep portion to the opening 41. Removal work is performed by sucking and removing contaminants such as fine lint and soap residue.

When the lint gripping cleaning work and the suction cleaning work by the pickup tool 29 are finished, cleaning and cleaning by the cleaning device is performed.
FIG. 9 shows a cleaning operation state near the opening 41 by the cleaning nozzle 50.

  When performing cleaning and cleaning using the opening 41, it is necessary to protect the water from entering the suction passage 16 from the suction-side surface 42 of the recess 40. As shown in FIG. 9, the surface 42 on the suction side on which the mesh is attached is covered with a protective material 51 such as a cloth during cleaning and cleaning.

The cleaning operation is performed by inserting the narrow tube 44 connected to the water discharge side of the cleaning nozzle 50 for jetting high-pressure water attached to the faucet of the water supply through the connection tube from the through portion 41a of the opening 41 to the inside of the air passage. This is done by discharging a high-pressure water flow into the air passage while the washing drum 3 is rotated. Water discharge is performed for 10 seconds to several tens of seconds at a time, and the cleaning operation is repeated a plurality of times. The state of cleaning by performing the cleaning operation can be confirmed by visual observation of the amount of lint and soap residue collected by the waste collection drain filter at the waste collection port 12. It is preferable to finish the cleaning operation after allowing the customer to visually confirm that the collected amount of the drainage filter has disappeared. By completing this cleaning operation, the air path cleaning performed by using the opening 41 for one set combined with the lint grip cleaning and the suction cleaning is completed.

  Next, in addition to air path cleaning using the opening 41, air path cleaning using the gap 48 between the washing drum 3 and the water tank 4 is performed.

FIG. 10 shows a cleaning operation using the gap 48 between the washing drum 3 and the water tub 4.
Since a narrow gap 48 communicating with the drying air passage 5 is formed between the washing drum 3 and the water tub 4, the gap 48 is used from the front side of the housing 2 by opening the door 6. Airway cleaning can be performed.

  In the case of capturing and storing the contamination state before cleaning prior to the air path cleaning using the gap 48, the camera head 25 is inserted through the gap 48 and dried in the same manner as the imaging using the opening 41 described above. The inside of the air path 5 can be imaged. The imaging of the contamination state before cleaning may be performed only by the imaging shown in FIGS. 6 and 7 previously performed.

  The airway cleaning work using the gap 48 includes lint grip cleaning by the pick-up tool 29, suction cleaning by the suction cleaner, and cleaning cleaning by the cleaning device, similarly to the cleaning work using the opening 41 described above. Can be implemented as a set. The set air path cleaning work can be performed by exchanging the cleaning work for the set using the opening 41 performed earlier and the front and rear. A part of the cleaning for the set to be performed later may be omitted depending on the contamination state.

  The lint gripping and cleaning operation can be performed by inserting the pickup unit 30 through the gap 48 with the open / close door 6 opened, pushing it into the deep portion of the drying air passage 5 and gripping the lint 43.

  In the suction cleaning operation, the gap suction nozzle 38 is inserted through the gap 48 with the open / close door 6 open, so that the inside of the drying air passage 5 can be moved deeply to suck and remove internal contaminants.

  In the cleaning operation, with the open / close door 6 opened, the narrow tube 44 connected to the water discharge side of the cleaning nozzle 50 for jetting high-pressure water is inserted through the gap 48 and introduced into the air passage. In addition, the washing drum 3 can be rotated by discharging a high-pressure water flow from the tip 45 of the narrow tube 44 into the air passage. Water discharge is performed for several minutes at a time, and the cleaning operation is repeated several times. The state of cleaning by carrying out the cleaning work can be confirmed by visual observation of the amount of lint and soap scum collected by the waste collection drain filter at the dust collection port 12 as in the cleaning work shown in FIG.

(3) Imaging of cleaned state after cleaning and storage of imaging information When the cleaning operation of the dry air passage 5 is completed, imaging in the air passage after cleaning is performed. As before the start of cleaning, the flexible scope 24 is set in the imaging mode, the camera head 25 is advanced into the air passage through the opening 41 and / or the gap 48, and imaging is performed, and imaging information relating to the internal state after cleaning is stored. ,save.

  According to the present embodiment, the imaging device (flexible scope 24) is inserted into the dry air passage 5 before and after cleaning, and the inside of the air passage is imaged, and the state before the cleaning start and the state after the cleaning are observed. Thus, the cleaning result of the dry air passage 5 that is difficult to visually recognize can be visualized, and the air passage cleaning can be performed with high accuracy and efficiency. With this visualization, when cleaning a drum-type washer / dryer as an agency service from the client, it is possible to improve the reliability of the client with respect to cleaning of the drying air passage and to achieve smooth operation. . In addition, the imaging information before and after the start of cleaning can be stored and stored, and the imaging information can be provided to the customer, and the imaging information before and / or after the cleaning can be clearly presented to the customer. Therefore, it is possible to compare the situation in the air passage before the start of cleaning and after the cleaning, which can contribute to the improvement of the reliability to the cleaning client.

  Since the cleaning result is visible from the collection of contaminants, only the imaging information before the start of cleaning may be provided to the customer for confirmation. Moreover, in order to confirm the cleaning result, only the imaging information after cleaning may be provided to the customer. Furthermore, imaging information before and after the start of cleaning can be used as work management data for the cleaning company.

  In the present invention, cleaning with the cleaning body is performed a plurality of times, and imaging and storage with the flexible scope 24 can be performed after each cleaning. That is, since the cleaning effect according to the progress of each cleaning can be clearly shown by visualization, the reliability of the client for cleaning the dry air passage 5 can be further improved in the agency service. The multiple cleanings can include not only cleaning by different cleaning means (for example, the pickup tool 29, suction cleaner, and cleaning device) but also cleaning by the same cleaning means.

<Washing of washing drum 3>
When the cleaning of the drying air passage 5 is completed, the washing drum 3 is washed using a deformer (tank washing cleaning liquid) such as a chlorine bleach. First, at a temperature of 40 to 50 ° C., a diluted washing liquid in which a small amount of deformer is added to about 4 L of hot water is put into the washing drum 3, and the washing drum 3 is rotated for several tens of minutes to perform drum washing and sterilization. Is done. After completion of the drum rotation, since the contaminants are floating in the liquid in the drum, the contaminants are collected with a scooping net. Next, after the diluted cleaning liquid is discharged, the same amount of water is put into the drum, and the washing drum 3 is rotated for several tens of minutes to perform drum water washing. The drum water washing is performed several times, and is completed when the collected matter is exhausted by another scooping net every time. When the washing of the washing drum 3 is completed, the rake net from which the contaminants are first recovered and the rake net from which the contaminants have disappeared after the cleaning are presented to the customer, and the drum washing result can be visually confirmed.
