Therefore, in order to open the lid #-69, the handhold pushes down the four parts 73 to release the locked state between the locking claw 72 and the locked claw 67, and then opens the lid body 69. At this time, the gravity of the weight 79 acts in the opening direction of the M body 69 to assist the opening operation, and when the opening is completed, the recess 70 comes into contact with the abutting rib 68. . Further, at this time, since the slide grooves 64 and 65 are formed in a U-shape, the sliding resistance of the lid 69 increases as the lid 69 is opened. Therefore, even if the lid body 69 is opened forcefully, the force is relaxed.

In addition, in order to close the lid 69, by sliding the lid 69 in the closing direction, the locking claw 72 is pushed up along the slope of the locking claw 67, and the locking claw 67 is pushed up.
Automatically locks at 7. At this time, if the lid 69 is not completely closed, the gravity of the weight 79 causes the lid 69 to close.

In addition, in this embodiment, in addition to the M body 69, ff1ll
Although a weight 79 is provided on the edge, in addition to this, one lid 6
The thickness of the other side edge of 9 is made larger than that of the one side edge,
The specific gravity of the other side edge may be increased, and the point is that the lid body 6
The weight of the end in the opening direction of 9 may be made larger than the weight of the end in the closing direction.

Further, as a means for gradually increasing the sliding resistance of the lid body 69 in the opening direction, as shown in FIGS. 1O and 11,
The depth PI of the slide groove 64 is in the opening direction of the lid 69 (
The depth P2 of the slide groove 65 may gradually become larger in the opening direction of the lid 69 (the direction of the arrow in the figure).

In such a configuration, during the washing process, the washing drum 44 is repeatedly reversed at low speed by the washing motor 82, and the laundry in the drum 44 is scooped up by the baffle and falls from above to below, which is a so-called pat washing process. At the same time, the horizontal ribs A54..., horizontal ribs B80
It is scrubbed and washed by... In addition, during the dewatering process, the washing drum 44 is rotated in one direction at high speed by the dehydrating motor 84, and the laundry in the drum 44 is dehydrated by a long distance cI force. Further, during the drying process, the washing drum 44 is repeatedly reversed at low speed by the washing motor 82, and the air duct 1-A17 and the suction port 58 are
Drying air is introduced into the drum 44 from the inside of the drum 44 and exchanges heat with the laundry inside the drum 44. Further, at this time, the ribs 49 provided on the balancer 46 prevent drying air from leaking out of the drum 44 from between the screw posts 48 .

In any of the steps, the horizontal ribs A54... and the horizontal ribs B80... provided in the drum 44.
As a result, the laundry adhering to the inner peripheral wall of the drum 44 is peeled off.
The laundry attached to the upper part of the drum 48 easily peels off and falls downward.

Next, a second embodiment of the present invention will be described based on FIG. 12.

Reference numeral 91 denotes a protruding wall that is integrally formed and protrudes downward at a position adjacent to the recess 70 in the lid body 69, that is, in close opposition to the open side wall surface 70a of the recess 70; It has the same width and height as 70.

When the lid body 69 is slid in the opening direction, the protruding wall 91 touches the abutment rib 68 at the opening completion position.
comes into contact with. Since the protruding wall 91 protects the recess 70 from impact caused by contact, the recess 70 does not need to be as long as in the first embodiment, and the thickness of the recess 70 can also be reduced. The handle can be shaped to suit the recessed part.

FIG. 13 shows the projecting wall 91 formed separately and the recess 7
It is screwed onto the position adjacent to 0. In this case, the material of the protruding wall 91 is preferably one having elasticity, such as hard rubber.

Effects of the Invention According to the configuration of the washing machine of the present invention, the recess for the handle for opening the lid also serves as a stopper for regulating the opening operation of the lid, so a separate stopper is provided. There is no need to provide a

Further, by providing a recess in the lid, deformation of the lid can be suppressed.

Furthermore, since the recess as a part of the handle abuts upon completion of opening the lid, it is easy to feel the touch at the time of abutment, and it is easy to judge whether the opening operation is complete.

Furthermore, by providing a protrusion that abuts the edge of the input port of the drum instead of the recess, the strength of the lid can be further reinforced.

Further, since the protrusion only needs to be placed adjacent to the recess, a high degree of dimension M is not required and manufacturing is easy.

Further, since the protrusion is adjacent to the recess, the contact feeling when the lid is completely opened is hardly reduced.
