That is, since the force applied to the fingers is reduced, the opening force of the lid 3 is reduced, and the operability is improved.

<Left and right shared>
In the embodiment described above, the lid 3 opens and closes on the left side of the washing and drying machine main body 4, but as another embodiment shown in FIG. 18, the lid 3 opens and closes on the right side of the washing and drying machine main body 4. Indicates. The difference from FIG. 1 is that the shape of the lid 3 is reversed left and right, the lid fulcrum means 9 is provided on the right side of the lid body 3, and the lock receiving means 26 is provided on the left side of the lid body 3. Is opened in the right direction indicated by the arrow. The AA cross section, the BB cross section, and the EE cross section in FIG. 1 are indicated by adding a 'to the corresponding cross section, and are left and right from FIGS. 4 to 6, 9 to 10, and 15 to 16. Symmetric configuration.

  In the configuration of FIGS. 1 and 18, the lid fulcrum means 9 including the hinge cover 10 and the operation recess 34 are both concentrically provided on the outer periphery from the lid 3, which is partitioned by the partition line 7 in this embodiment. It is provided inside the lid peripheral dividing surface 8. Therefore, by making the dividing line 7 that forms the outer periphery of the lid peripheral dividing surface 8 into a symmetrical circle, the opening direction of the lid 3 is a left-open configuration as shown in FIG. 1, and a right side shown in FIG. In the open configuration, the parts inside the lid peripheral dividing surface 8 are different symmetrical parts, but since the front cover 22 can be configured in common, the structure can be simplified.

<Effect>
Further, according to the present embodiment, since the connecting member for connecting the hinge pin 19 which is the rotation shaft of the lid fulcrum means 9 and the lid 3 is unnecessary, the configuration of the rotation fulcrum can be simplified and the lid 3 is supported. The rigidity is high, and there is no need for an inner space for storing the connecting member when the lid 3 is closed, and there is an effect that it is suitable for downsizing.

  Further, when the lid 3 is closed, the hinge cover 10 is flush with the lid peripheral dividing surface 8, and the outer periphery of the lid peripheral dividing surface 8 and the hinge cover 10 are both formed by a dividing line 7 concentric with the lid 3. Therefore, since no step is required between the lid 3 and the lid peripheral dividing surface 8 or the front cover 22, the lid 3 does not protrude from the front cover 22, and the depth direction of the washing and drying machine body 4 is covered with the lid 3. There is an effect that it is not necessary to enlarge the step of the body 3 and is suitable for downsizing.

  Furthermore, the lid peripheral dividing surface 8 and the hinge cover 10 form a ring shape with the outer surface of the lid 3 and the surface separated by the dividing line 7 being the same surface when the lid 3 is closed, and further operation Since the recess 34 is provided only on the inner side of the lid peripheral dividing surface 8, the dividing line 7 with the front cover 22 can be a continuous uniform circle concentric with the lid 3, so that an extra part dividing line, etc. And there is an effect that a simple configuration and appearance can be realized.

Further, according to the present embodiment , since the operation recesses are provided on the outer side and the rear side of the lid body 3 corresponding to the operation handle 12 that opens the lid body 3, the operation handle is opened when the lid body 3 is opened. 12 is easy to operate and the lid 3 can be easily opened.

Further, according to the present embodiment , the bracket recess groove 21 which is a notch provided in the lid 3 so that the hinge bracket 18 and the lid 3 do not interfere with each other is covered from the front by the hinge cover 10, so that the foreign matter from the notch There is an effect that there is no fear of entering or opening / closing.
