Since it is located in the upper left part off the center of the curved surface of the front surface of the housing 2, it can be said that when viewed from the front of the washer / dryer housing 2, it is substantially rectangular in appearance (FIG. 5A). (See) From the viewpoint perpendicular to the handle cover 27, the lower right corner and the upper left corner are formed at an angle (acute angle) slightly smaller than 90 °, and the upper right corner and the lower left corner are slightly larger than 90 °. It is formed at a large angle (obtuse angle) (see FIG. 5B). That is, the handle cover 27 located at the upper left part off the center of the curved surface of the front surface of the washer / dryer casing 2 has a substantially parallelogram shape with the lower right and upper left corners formed with slightly acute corners. The right side 26b and the left side 26c adjacent to the lower side 26a of the support frame portion 26 are parallel to the lower side of the support frame portion, and the rotary shaft (the rotary shaft end piece 28 and the rotary bearing portion described later). 29). On the upper side and the left and right sides of the handle cover 27, an edge portion 27a that abuts on the peripheral edge portion of the opening portion 25 with the handle cover 27 closed is formed with a step that bends to the back side. When the handle cover 27 is closed, the surface of the handle cover 27 that is inscribed in the opening 25 is flush with the surface of the front cover 24 (it is fitted in the opening 25). The portion excluding) has substantially the same contour shape as the opening 25 of the front cover 24.

  As described above, the handle cover 27 is attached to the lower side 26a of the support frame portion 26b so as to be rotatable about an axis parallel to the lower side 26a. The cover 27 is pressed and rotated, and the detergent container 22 can be pulled out by inserting a finger into a space formed between the lower end of the front cover 24. That is, the rotary shaft end piece 28 in which the rotary shaft ends 28 a protrude outwardly from each other at positions near both ends of the lower portion on the back side of the handle cover 27 and the support frame portion 26. A rotation bearing portion 29 having a rotation bearing hole 29a through which the rotation shaft end 28a is inserted is erected at a position facing the rotation shaft end piece 28 on the lower side on the back side. The rotation shaft end piece 28 is inserted into the rotation bearing hole 29 a of the rotation bearing portion 29, so that the rotation shaft end piece 28 is rotatably engaged with the rotation bearing portion 29. In other words, the line segment connecting the two rotation shaft end pieces 28 functions as a rotation shaft, and the handle cover 27 (rotation shaft end piece 28) is connected to the support frame portion 26 (rotation bearing portion 29). And is pivotally attached.

  In the present embodiment, the rotating shaft end piece 28 on the left side (left side in FIG. 6 and right side in FIG. 7) viewed from the back side, which is erected on the lower side of the back side of the handle cover 27, and Opposite end surfaces 28b and 29b facing each other with a rotating bearing portion 29 erected on the lower side on the back side of the support frame portion 26 have a helical inclination for each 120 ° section divided into three. The sliding contact surfaces 28c and 29c are formed (see FIG. 8). The sliding contact surfaces 28c and 29c formed on the rotary shaft end piece 28 and the end surfaces 28b and 29b of the rotary bearing portion 29 have a shape protruding along the counterclockwise direction, and the handle cover 27 is washed. As the dryer casing 2 is rotated in the depth direction, the rotation shaft end piece 28 is moved from the rotation bearing portion 29 while the end surfaces 28 b and 29 b (sliding contact surfaces 28 c and 29 c) come into contact with each other. In this direction, the handle cover 27 is displaced so as to move in the right direction when viewed from the back side. In this way, the sliding contact surfaces 28c and 29c having a spiral inclination are formed on the end surfaces 28b and 29b of the rotation shaft end piece 28 and the rotation bearing portion 29, thereby moving the handle cover 27 by a moving mechanism (lid Plate moving mechanism).

  The sliding contact surfaces 28c and 29c formed on the end surfaces 28b and 29b with a spiral inclination are provided on the end surfaces 28b and 29b of both the rotating shaft end piece 28 and the rotating bearing portion 29. It may be provided on either one of the end faces 28b or 29b. When the slidable contact surfaces 28c and 29c are inclined on both the end surfaces 28b and 29b, the inclination angle of the slidable contact surfaces 28c and 29c is compared to the case where the slidable contact surfaces 28c and 29c are provided on either one of the end surfaces 28b or 29b. Is the same, the amount of movement of the handle cover 27 can be doubled. Further, in the case where either one of the end faces 28b or 29b is provided with the slidable contact surface 28c or 29c, if the slidable contact surface 28c or 29c is set to have a double inclination angle, both end faces 28b and 29b are The amount of movement of the handle cover 27 equivalent to the case where the sliding contact surfaces 28c and 29c are provided can be obtained.
