  As shown in FIGS. 3, 7, and 8, the filter frame 76 is provided with a collecting member. The collecting member includes an upstream net filter 90 and a downstream net filter 91. The upstream side net filter 90 has a bag shape, and the downstream side net filter 91 has a flat plate shape.

  The downstream net filter 91 is finer than the upstream net filter 90. Most of the lint is collected in a bag-like upstream net filter 90. Fine dust that has passed through the upstream net filter 90 is collected by a fine downstream net filter 91.

  The collection member is cleaned by removing the filter frame 76 from the filter case storage portion 71. Most of the lint was collected by the upstream net filter 90 and was formed into a bag shape. Since there is little lint collected by the downstream net filter 91, it was made flat. Since it is collected by the two-stage net filter, there is almost no lint passing through the collecting member.

  As shown in FIGS. 3 to 7, the front panel 77 includes an operation knob 92 on the front side (front side) and a lock lever 93 on the back side. An attachment frame 94 is provided on the back surface of the front panel 77. The attachment frame 94 is formed integrally with the front panel 77.

  As shown in FIGS. 3, 4, and 7, a bearing 97 that rotatably supports the lock lever 93 is provided on the back surface of the front panel 77. The bearing portion 97 is located at the center of the mounting frame 94. As shown in FIGS. 3, 4, and 6, a rotation support portion 98 provided in the middle of the lock lever 93 is fitted to and supported by the bearing portion 97.

As shown in FIGS. 3, 4, and 7, the operation knob 92 includes a support shaft 110 at the center and locking arms 111 on both sides of the support shaft 110. The support shaft 110 and the locking arm 111 of the operation knob 92 are inserted from the front side of the front panel 77. The support shaft 110 is inserted into the insertion hole 112, and the locking arm 111 is inserted into the groove hole 113.

  Further, the support shaft 110 is formed into a fitting hole 114 existing at the center of the rotation support portion 98 of the lock lever 93, and the locking arm 111 is a lock receiving hole provided in the vicinity of the rotation support portion 98 of the lock lever 93. Is inserted and locked.

  By the insertion of the support shaft 110 and the insertion locking of the locking arm 111, the operation knob 92 and the lock lever 93 are coupled with the front panel 77 interposed therebetween, and are rotatably supported by the bearing portion 97 of the front panel 77. .

  Since the lock lever 93 is coupled to the operation knob 92, the lock lever 93 rotates by turning the operation knob 92. By this rotation, the lock lever 93 is disengaged from a locking portion described later.

  As shown in FIGS. 6, 7, and 13, the urging spring 115 urges the lock lever 93 to be engaged with the locking portion.

As shown in FIGS. 10 and 11, the biasing spring 115 includes a spring portion 116 and a fixing portion 117 that is continuous with the spring portion 116. The spring part 116 has a semicircular contact part 118. As shown in FIG. 13, the contact portion 118 contacts the lock lever 93 and presses the lock lever 93.

  The lock lever 93 is urged by the urging spring 115 in the M direction shown in FIG. 13, and the engagement of the lock lever 93 is maintained.

As shown in FIG. 13, the urging spring 115 is supported by a spring support portion 130 provided on the front panel 77 constituting the filter case 73.

  FIG. 12 shows a state before the biasing spring 115 is attached to the spring support portion 130. The spring support portion 130 has a stop protrusion 131 at the center. The fixing portion 117 of the urging spring 115 has a stop hole 132. By fitting the fixing portion 117 of the urging spring 115 into the spring support portion 130, the stop protrusion 131 is fitted into the stop hole 132.

  As shown in FIGS. 10 and 11, the urging spring 115 has a V-shaped pin receiving portion 133 where the spring portion 116 and the fixing portion 117 are connected.

  As shown in FIGS. 12 and 13, the stop pin 134 is provided in the vicinity of the spring support portion 130.

When the biasing spring 115 is attached to the spring support portion 130, the stop pin 134 is fitted into the pin receiving portion 133 of the biasing spring 115.

  By fitting the fixing portion 117 of the biasing spring 115 into the spring support portion 130 in this way, the stop protrusion 131 is fitted into the stop hole 132, and the stop pin 134 is fitted into the pin receiving portion 133 of the bias spring 115. For this reason, the biasing spring 115 is firmly fixed to the spring support portion 130.

  Further, since the stop pin 134 supports the root of the spring portion 116, the operation of the biasing spring 115 is stabilized, and the lock lever 93 is reliably engaged.

  As shown in FIGS. 9 and 14 to 16, the locking portion 190 is disengaged from the distal end side of the lock lever 93. The engagement / disengagement of the lock lever 93 is performed by rotating the operation knob 92.

By engaging the lock lever 93 with the locking portion 190, the filter case 73 attached to the filter case storage portion 71 is securely fixed and held without coming off. The filter case 73 can be pulled out to the filter case storage portion 71 by turning the lock lever 93 and releasing the lock lever 93 from the locking portion 190.

  As described above, since the lock lever 93 is reliably engaged with and disengaged from the locking portion 190 by the rotation of the lock lever 93, the filter case 73 to be taken in and out of the filter case storage portion 71 can be easily attached and detached.

As shown in FIGS. 9 and 14 to 16, the locking portions 190 are provided on both sides of the front side of the inlet 75 of the filter case storage portion 71 into which the filter case 73 is put in and out. In addition, the locking portion 190 is provided at a position retracted outward from around the entrance 75.

  As shown in FIG. 9, the locking portion 190 has an inclined surface 191 that is inclined from the front side toward the back side, and a substantially vertical locking surface 192 that is continuous with the back side of the inclined surface 191. The right locking portion 190 has an inclined surface 191 that is inclined upward. Conversely, the right locking portion 190 has an inclined surface 191 with a downward slope.

  As described above, both ends of the lock lever 93 are disengaged from the engaging portion 190 when the filter case 73 is inserted into and removed from the filter case storage portion 71. When inserting the filter case, the lock lever 93 is pressed against the inclined surface 191.

  Accordingly, the lock lever 93 turns counterclockwise against the biasing spring 115. Then, after passing the tip of the inclined surface 191, it is urged by the force of the urging spring 115 and rotates in the reverse direction (clockwise), and the lock lever 93 is engaged with the locking surface 192.

  In this way, the filter case 73 is easily mounted by being pushed into the filter case housing portion 71 into the filter case 73, and the state where the filter case 73 is mounted by the engagement of the lock lever 93 with the locking surface 192 is securely maintained. It is.

  When removing the filter case 73 from the filter case storage portion 71, the lock lever 93 is detached from the locking surface 192 by turning the operation knob 92 counterclockwise. Since the filter case 73 is pulled out from the filter case storage portion 71 by grasping and pulling the operation knob 92, it can be easily removed.

  14 and 15 show a state in which the filter case 73 is attached to the filter case storage portion 71 and the lock lever 93 is engaged with the locking surface 192 of the locking portion 190. FIG. FIG. 16 shows a state in which the operation knob 92 is turned to release the lock lever 93 from the locking surface 192.

  As shown in FIGS. 6, 7, and 14 to 16, the operation rod 194 is provided on the rear surface side of the front panel 77 so as to protrude toward the back. The filter case storage unit 71 includes a detection switch (not shown) that knows whether the filter case is attached or detached.

  The detection switch (not shown) is operated by the operation rod 194 in accordance with the attachment / detachment of the filter case 73 to / from the filter case storage portion 71. The operation of the operation rod 194 can be used to detect the attachment / detachment of the filter case 73 with the detection switch.

  As shown in FIGS. 9 and 14 to 16, the flange portion 195 is provided at the outer peripheral edge of the inlet 75 of the filter case storage portion 71. The flange portion 195 is provided with an operation rod guide hole 196 through which the operation rod 194 enters and exits.

  If the operating rod 194 is not passed through the operating rod guide hole 196, the detection switch does not operate. For this reason, even if the filter case 73 is mounted in the wrong direction, the detection switch does not operate, so that the drying operation is not performed and the malfunction is avoided.

  As shown in FIGS. 3 to 5, the front base frame plate portion 78 includes a front seal member 197 on the outer peripheral edge. The front seal member 197 contacts and separates from the inner peripheral surface of the inlet 75 or closer to the inner peripheral surface when the filter case 73 is inserted into and removed from the filter case storage portion 71.

  The front seal member 197 keeps the inside and outside of the filter case 73 airtight, so that the drying air flowing through the drying air circulation path does not leak.

  As shown in FIGS. 14 to 16, the distal end side of the lock lever 93 projects outward from the inner peripheral edge of the inlet 75 and the outer peripheral edge of the front base frame plate portion 78. The mounting frame 94 of the front panel 77 has lock lever cutouts 198 on both sides. The distal end side of the lock lever 93 is accommodated in the lock lever notch 198 and rotates within this range.

  The locking portion 190 is provided at a position retracted to the outside from the periphery of the inlet 75 in consideration of the insertion and removal of the filter case 73. In order to engage and disengage from the locking portion 190 at this position, the distal end side of the lock lever 93 protrudes outward from the inner peripheral edge of the inlet 75 and the outer peripheral edge of the front base frame plate portion 78.

  On the other hand, if the locking portion 190 protrudes into the inlet 75, it is necessary to provide relief grooves extending in the front and rear sides to avoid the locking portion 190 on both sides of the filter case 73 to be taken in and out.

  With such a structure, the filter case 73 has a complicated structure. In addition to this, it becomes difficult to arrange the collecting member for collecting lint.

  In consideration of such circumstances, the locking portion 190 is provided at a position retracted outward from the periphery of the inlet 75, and the distal end side of the lock lever 93 is set from the inner peripheral edge of the inlet 75 and the outer peripheral edge of the front base frame plate portion 78. Also created a structure that protrudes outward.
