In the dryer 1 having the above structure, as shown by the solid line in FIG.
When the lint filter 7 is sufficiently lowered and the lint filter 7 obliquely traverses the flow path of the exhaust flow path 6, the lint L in the exhaust gas passing during drying can be captured by the lint filter 7. Then, the filter cleaning start condition under the filter management control by the control device 9 (for example, the cumulative operating time reaches a predetermined number of hours) after the end of the day's business or after the predetermined number of drying steps are completed. Or the number of times of drying reaches a predetermined number), the cleaning of the lint filter 7 is automatically started. The cleaning of the lint filter 7 can be started by manually operating a cleaning start switch (not shown) provided on the operation panel.

When the cleaning of the lint filter 7 is started, the suction device 31 is started by a signal from the control device 9, so that an intake flow is generated at the nozzle opening 30 'of the intake nozzle 30, and the intake flow causes the lint filter to flow. It is possible to suck and remove lint L such as thread waste accumulated in the upper end portion of 7 and near the filter insertion port 24. Then, the drive motor 38 of the drive mechanism is slightly delayed from the start of the suction device 31.
Starts to move the filter feed member 26, whereby the lint filter 7 starts moving from the inside of the exhaust passage 6 to the outside, that is, starts to rise.

When the lint filter 7 starts to rise, the nozzle opening 30 arranged outside the filter insertion port 24.
Since the intake air flow is generated in ′, the lint L adhering to the surface of the lint filter 7 is sequentially sucked and removed from the upper side as the lint filter 7 rises. And

And a second detector 62b for detecting the backward regulation position of 1. When the rotating arm member 61 acts on the first detector 62a and the second detector 62b, the detector 62 sends a stop signal to the control device 9. The control device 9 which has sent this signal and received this stop signal stops the drive motor 38, so that the rotating arm member 61
The rotation range of, that is, the rotation range of the lint filter 7 is restricted.

The driving arm member 5 is provided on the floor of the duct 55.
A through hole is formed in the range in which 8 moves, and a slide plate 64 that closes the through hole is attached from the lower surface (outer surface) of the duct 55 so that it can slide with the drive arm member 58.
In addition, the drive arm member 58 has the slit hole 6 of the slide plate 64.
5, when the drive arm member 58 rotates, the slide plate 64 moves in the front-rear direction along the lower surface of the duct 55, and the blower 8 operates to suck and exhaust air into the drying chamber 3, Since the pressure P1 on the downstream side of the lint filter 7 becomes lower than the pressure P2 on the upstream side, the slide plate 64 comes into close contact with the lower surface of the duct 55, whereby exhaust gas does not pass through the lint filter 7 and the through hole of the duct 55 is formed. It prevents you from passing through.

In the second embodiment having such a structure, as shown by the solid line in FIG. 7, the drive arm member 58 is inclined to the upstream side and the lint filter 7 makes the flow path of the exhaust flow path 6 into an arc surface. In the normal state traversed, the lint in the exhaust gas passing during drying can be captured by the lint filter 7.

When the cleaning of the lint filter 7 is started, the suction device 31 is started by a signal from the control device 9, so that an intake flow is generated in the nozzle opening 30 'of the intake nozzle 30, and the intake flow causes the lint filter to flow. It is possible to suck and remove lint such as yarn waste accumulated in the upper end portion of 7 or in the vicinity thereof. Then, after a short delay from the start of the suction device 31, the drive motor 38 of the drive mechanism starts and starts to rotate the drive arm member 58, which causes the lint filter 7 to form an arc-shaped exhaust passage 6 along the filter guide 56. Begins to rotate toward the downstream side of.

When the lint filter 7 starts to rotate, intake air flow is generated in the nozzle opening 30 'arranged in the opening close to the top of the lint filter 7, so that it adheres to the surface of the lint filter 7. The lint that is present is sequentially removed by suction as the lint filter 7 rotates. Then, when the lint filter 7 is rotated about 90 degrees and the entire surface of the lint filter 7 is cleaned, the rotating arm member 6
Since 1 acts on the second detector 62b and sends a stop signal, the control device 9 determines the backward movement regulation position and once stops the drive motor 38 and then reversely rotates the suction motor 3 as well.
Stop 1

When the cleaning of the lint filter 7 is completed in this way and the drive motor 38 rotates in the reverse direction, the lint filter 7 returns and rotates, and when it rotates to a predetermined position, the rotating arm member 61 causes the first detector to move. The control device 9 recognizes that the lint filter 7 has been lowered to a predetermined position by acting on the 62a, whereby the control device 9 stops the drive motor 38 and completes the cleaning process.
