Thus, when the finger or tool is released from the tilted retaining piece 206, the retaining piece 206 returns to an upright state, and the retaining piece 206 comes into contact with the other end 29a of the shaft 29 (slightly The movement of the shaft 29 in the axial direction is restricted (opposite with a gap) (see FIG. 7B). Thereby, it is possible to suitably prevent the shaft 29 from falling off after assembly.
The shaft 29 can be easily assembled through the opening of the notch 200e (see FIG. 9A) before the handle 20 is attached to the frame body 200.
Further, the biasing spring 28 may be locked after the shaft 29 is inserted, or may be performed before the shaft 29 is inserted.

  As shown in FIGS. 7B and 9B, a closing prevention member 200b is disposed on the side of the locking mechanism. The closing prevention member 200b is a member that restricts the closing of the lid body 2, and can be protruded rearward of the lid body 2 by rotating using an engaging member such as a coin. In the protruding state, the closing prevention member 200b can come into contact with the edge of the charging port 1g, and the closing of the lid 2 is prevented by this contact.

As shown in FIGS. 10 (a) and 10 (b), the fixed cover 220 has a thin ring shape that is fixed to the rear surface of the frame body 200, and has a portion corresponding to the handle 20 (see FIG. 6 (b)). A concave portion 224 is formed.
As shown in FIG. 10B, screw holes 222 are formed in the fixed cover 220 at positions corresponding to the bosses 203 (see FIG. 7A) of the frame body 200 at predetermined intervals in the circumferential direction. Has been. Further, the fixing cover 220 is inserted with contact member holes 223 and 223 through which the contact members 200c and 200c (see FIG. 7A) are inserted, and a locking hook 21 (see FIG. 7A). A locking hook hole 227 and a closing prevention member hole 228 into which the closing prevention member 200b (see FIG. 7A) is inserted are formed.

  The inner peripheral edge 225 of the fixed cover 220 is curved in a curl shape (substantially C-shaped in cross section) as shown in FIG. As shown in FIG. 11B, the inner peripheral edge 225 abuts on the curved portion 233 of the flange portion 232 of the door glass 230 to play a role of pressing the flange portion 232. Here, since the front end portion 225a of the inner peripheral edge portion 225 is curved inward, it corresponds to the radius of the curved portion 233 of the flange portion 232, and abuts against the curved portion 233 on the surface. It becomes.

  As a result, the flange portion 232 of the door glass 230 can be firmly pressed by the inner peripheral edge portion 225 of the fixed cover 220, and the flange portion 232 is pressed by contacting with the surface. No damage is caused by the contact of the inner peripheral edge 225. Accordingly, the door glass 230 can be prevented from being damaged.

As shown in FIG. 11A, the door glass 230 has a substantially hat-shaped cross section, and the flange portion 232 formed on the peripheral portion is a fixed cover 220 and is attached to the attachment portion 200g of the frame body 200 (FIG. 11B). )), The frame body 200 and the fixed cover 220 are held so as not to fall off.
An inclined surface 231 is formed on the upper portion of the door glass 230. The inclined surface 231 serves to suitably guide the hot air blown out through the opening of the outer tub 4 into the drum 3.
As shown in FIG. 7A, the flange portion 232 of the door glass 230 is formed with projecting portions 235 and 235 projecting in the radial direction, and these projecting portions 235 and 235 are formed in the frame body 200. It is latched by a positioning member (not shown) provided in FIG. Thereby, it is prevented suitably that the door glass 230 rotates in the circumferential direction of the frame body 200.

Next, an operation when the handle 20 is opened will be described.
As shown in FIG. 12 (a), in the closed state of the lid 2, a gap S1 is formed between the base 22 of the handle 20 and the rear opening edge 1c3 of the insertion port 1g, and the base 22 has a rear opening edge. 1c3 is in a non-contact state.
Further, the first extending portion 23a and a part of the second extending portion 23b of the finger hanging portion 23 are the outer peripheral surface of the frame body 200 (side edge portion 211 of the window member 210) and the side opening edge of the insertion port 1g. It arrange | positions in the non-contact state in clearance gap S2 formed between 1c2.

  Thus, in the closed state of the lid body 2, as shown in FIG. 13A, the end portion 21 a of the support portion 21 c of the locking hook 21 contacts the flat contact surface 21 c 1 at the end portion of the handle 20. As shown in FIG. 13 (b), the locking portion 21m of the locking hook 21 is locked to the locking receiving portion 1m provided on the rear opening edge 1c3 (see FIG. 12 (a)). (See FIGS. 15 (a) and 15 (b)), the closed state of the lid 2 is maintained.

On the other hand, as shown in FIG. 12B, when the handle 20 is opened, the handle 20 rotates about the rotation shafts 22a and 22b (rotates in the direction of the arrow in the figure), and the second extending portion 23b. Is moved to the front surface of the lid 2 (the edge of the window member 210) and overlaps with this.
At this time, the corner portion 23d of the finger hanging portion 23 passes through the gap S2 in a non-contact state without contacting the side opening edge 1c2 of the insertion port 1g, and the second extending portion 23b It rotates without contacting the side edge 211 of the window member 210. Therefore, at the time of the opening operation, there is no sense of resistance as when the corner 23d contacts the side opening edge 1c2 or the side edge 211 of the window member 210. Therefore, a smooth opening operation of the handle 20 is realized.

When the handle 20 is thus opened, as shown in FIG. 14A, the extending portion 22c of the handle 20 rotates rearward in the figure, and the end portion 21a of the support portion 21c of the locking hook 21 is moved. , Pushed backwards. Thereby, the locking hook 21 rotates in the direction in which the locking of the locking hook 21 is released.
Here, when the extending portion 22c of the handle 20 rotates rearward in the figure, as shown in FIG. 14B, the contact position of the end portion 21a of the locking hook 21 is on the flat contact surface 21c1. Then, the state moves to the inclined portion 22d and moves upward on the inclined portion 22d. That is, with the opening operation amount (rotation amount) of the handle 20, the amount by which the end portion 21 a of the locking hook 21 is pushed rearward (the amount that rotates in the release direction) is gradually increased.
As a result, as shown in FIG. 14B, the locking portion 21m of the locking hook 21 is surely released from the locking receiving portion 1m provided on the rear opening edge 1c3 (see FIG. 12A). Thus, the lid body 2 is turned to the unlocking position (see FIG. 15B), and the closed state of the lid body 2 is released.
As a result, even if there is an error in the dimensions of the molded product such as the handle 20 or the locking hook 21 or there is a variation during assembly, the locking hook 21 is securely turned to the locking release position. It can be moved.

  As shown by a two-dot chain line in FIG. 15 (b), the protruding portion 21p formed on the side of the locking hook 21 is locked when the locking hook 21 is rotated to the locking release position. The inner surface 1p of the receiving portion 1m or the edge of the locking hook hole 227 of the fixed cover 220 is abutted (the one abutting on both is shown in FIG. 15 (b)). The rotation of the hook 21 beyond the unlocking position is restricted. Accordingly, it is possible to realize a suitable rotation of the locking hook 21.

  According to the drum-type washing and drying machine of the present embodiment described above, the finger hook portion 23 has the bent portion 25 in which the middle portion extending from the outer peripheral edge portion of the lid body 2 is bent toward the center of the lid body 2. Since a part of the bent portion 25 and the front surface of the lid body 2 overlap each other when viewed from the front surface of the lid body 2, the outer circumferential edge portion of the lid body 2 faces to the side as in the past. Thus, unlike the case where the structure in which the finger-hanging portion extends is adopted, it is not necessary to provide the front cover 1c with a concave space for inserting a hand on the rear side of the finger-hanging portion 23, and the design is excellent.

  Moreover, since it is not necessary to provide a concave space in the front cover 1c, a drum-type washing and drying machine can be manufactured without changing the formwork for forming the front cover 1c and the like. Thereby, the manufacturing cost can be suppressed and a drum type washing / drying machine contributing to the improvement of productivity can be obtained.

  In addition, the drum type washing and drying machine of the present embodiment has a configuration in which such a concave space is not provided in the front cover 1c, but a finger hooking portion is provided from the outer peripheral edge portion of the lid body 2 to the side as in the related art. Compared to the extending structure, the lateral protrusion (protrusion amount) of the lid body 2 can be reduced, and the forward protrusion (protrusion amount) of the lid body 2 can be reduced. Excellent design. In addition, it is difficult for problems such as the laundry to be caught on the handle 20 when the laundry is taken in and out.

  Further, since the bent portion 25 is formed in the finger-hanging portion 23, a recess for finger-hanging can be easily formed (secured) by using the bent portion 25, and the opening operability of the lid 2 is excellent. .

  In addition, since an insertion space 27 into which the fingertip hung on the finger hanging portion 23 can be inserted is formed inside the bending portion 25, the fingertip can be easily inserted inside the bending portion 25 during the opening operation. It is possible to easily grasp the finger-hanging portion 23 (third extending portion 23c). Therefore, a drum-type washing and drying machine excellent in the opening operability of the lid 2 can be obtained.

Further, since the finger-hanging portion 23 has a finger-hanging surface 24a along the front surface of the lid body 2, the handle 20 is rotated so that the finger is in close contact with the finger-holding surface 24a during the opening operation. Can do. Therefore, a drum-type washing and drying machine excellent in the opening operability of the lid 2 can be obtained.
In this case, since the finger can be brought into close contact with the finger hooking surface 24a while inserting the fingertip inside the bent portion 25, a force is easily applied to the finger to be opened by these synergistic effects. Therefore, a drum type washing / drying machine excellent in the opening operability of the lid 2 is obtained.

The handle 20 has a third extending portion 23c provided through a relatively long extending portion including the first extending portion 23a and the second extending portion 23b. Since the finger hooking portion 23 (second extending portion 23b, third extending portion 23c) of the handle 20 is configured to turn around the front side of the window member 210 with a space therebetween, It is possible to easily ensure the rotation required to release the valve 21 and to avoid the handle 20 from coming into contact with the window member 210.
Thereby, in the window member 210, it is not necessary to provide a recess or the like for rotating the handle 20, and it is not necessary to change a mold for forming the window member 210. Therefore, the manufacturing cost of the drum type washing / drying machine can be suppressed.

Although the present invention has been described in detail based on the embodiments, the contents of the present invention are not limited to the above description, and various modifications and changes can be made without departing from the spirit of the present invention. include.
For example, the shape of the to manual 20, as long as it has a bent portion 25 may employ any of various shapes.
