  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 is a cross-sectional view of a drum-type washing machine according to a first embodiment of the present invention, FIG. 2 is a front view of the drum-type washing machine, and FIG. 3 is a cross-sectional view of main parts of the drum-type washing machine. It is.

  In FIG. 1, the rotating drum 11 is formed in a bottomed cylindrical shape, and has a large number of water passage holes 12 on the entire outer periphery, and is supported in a vibration-proof manner in the washing machine housing 16. It is rotatably arranged in the bottom cylindrical water tank 13. A rotation shaft (rotation center shaft) 14 is provided at the rotation center of the rotary drum 11, and a motor 15 attached to the rotation shaft 14 in the vicinity of the back surface of the water tank 11 is connected via a belt 26. Are driven to rotate in the forward and reverse directions.

  A housing garment doorway 17 provided in the washing machine casing 16 on the front side of the aquarium 13 is covered with a lid body 18 so as to be freely opened and closed. The laundry is put into the rotary drum 11 through the seal packing 20 and the rotary drum clothing entrance 21 which are mounted in a shape so that the laundry can be taken out from the rotary drum 11.

  The lid 18 is rotatably supported by a rotation support portion 22 formed on a pair of upper and lower rotary shaft members 23 disposed in the washing machine casing 16, and when the lid 18 is closed, a seal composed of a rubber material or the like. The housing 20 is sealed with the packing 20.

  In FIG. 2, the lid 18 has an end face side 18 a (left side portion of the rotation support portion 22 in FIG. 2) and a center side 18 b (right side of the rotation support portion 22 in FIG. 2) with the rotation support portion 22 as a boundary. Part). Here, the end face side 18 a of the lid 18 rotates to the washing machine housing 26 side in conjunction with the opening operation of the lid 18. On the other hand, the center side 18 b of the lid 18 rotates to the opposite side of the washing machine casing 16 in conjunction with the opening operation of the lid 18.

  In FIG. 3, the larger the opening angle of the lid 18, the easier the laundry can be taken in and out of the rotary drum 11. However, since the rotary shaft member 23 and the lid 18 interfere when the lid 18 is opened, the lid A notch 24 is formed on the end face side of 18. In addition, the notch 24 maintains the clearance a with the rotary shaft member 23 when the lid is fully opened.

  In addition, a pair of upper and lower convex portions 25 is formed in the washing machine casing 16 at a position corresponding to the notch portion 24 in the vicinity of the pair of rotating shaft members 23, and the gap between the notch portion 24 and the lid body is formed. Even if 18 rotates, it is set below the gap b. Further, the gap between the lid 18 and the washing machine housing 16 is set to be equal to or less than the gap b, similarly to the notch 24 of the lid 18. The gap b is a dimension that does not allow the tip of the finger to enter, and is set to approximately 5 mm.

  Further, the shape of the convex portion 25 may be formed integrally with the washing machine casing 16 as shown in FIG. 3 or may be made of metal or resin and arranged in the washing machine casing 16 as a separate part from the washing machine casing 16. You may do it. If the convex part 25 is formed as a separate part, especially when the washing machine casing 16 is formed of metal, restrictions on manufacturing such as the elongation rate of the metal are eased, and the gap b of the notch part 24 is further increased. It can be kept accurate. If a flexible material such as rubber is used, the gap between the notch 24 of the lid 18 and the projection 25 of the washing machine housing 16 is eliminated, and the notch 24 of the projection 25 and the lid 18 is eliminated. Even if they are brought into contact with each other, since the convex portion 25 bends when the lid 18 is opened and closed, the lid 18 is not obstructed from opening and closing.

  The operation and action of the drum type washing machine configured as described above will be described below.

  In order for the user to wash the laundry, the locking mechanism (not shown) between the lid 18 and the washing machine casing 16 is released, and the lid 18 is opened. At this time, the notch 24 of the lid 18 and the end face side 18a of the lid 18 are rotated toward the washing machine housing 16 in conjunction with the opening operation.

At this time, if there is a gap between the notch 24 of the lid 18 and the end face side 18a of the lid 18 and the washing machine housing 16, the fingers of an attendant such as an operator and a child can enter, the lid 18 With the opening operation, the lid 18 moves in the direction in which the finger is compressed, which is dangerous. However, the gap between the notch 24 of the lid 18 and the end face side 18a of the lid 18 and the washing machine casing 16 is less than the gap b where the fingers cannot enter due to the pair of convex portions 25 provided on the washing machine housing 16. Since it is set to (for example, 5 mm or less), it is possible to avoid the danger that a finger does not enter. That is, the distance when the distance between the convex portion 25 and the lid 18 is the closest is set to a predetermined distance (for example, 5 mm) or less. Therefore, the opening angle of the lid 18 is increased and the lid 18 is cut. The notch portion 24 is formed and can be opened and closed safely without impairing the convenience of putting in and out the laundry.

  Further, the rotation support portion 22 of the lid body 18 is formed on the rotary shaft member 23 and is disposed in the washing machine casing 16, and the rotation support portion 22 has a simple configuration in which the lid body 18 is only rotationally supported. For this reason, for example, the above-described safety can be ensured without taking a complicated configuration such as the rotation support portion 22 having two axes, and variations due to stacking of components can be reduced, and rattling of the lid 18 can be reduced. Can do. That is, it is possible to prevent the product quality from being impaired.

  As described above, in the present embodiment, the lid body has a notch portion at a position corresponding to the rotating shaft member, and the washing machine housing has a pair of convex portions at a position corresponding to the notch portion. By forming and setting the distance between the convex part and the rotation trajectory of the notch part and the end part of the lid body to a predetermined distance or less where the finger cannot enter, it is possible to safely cover the gap without putting a finger into the gap. The body can be opened and closed.

(Embodiment 2)
Although not shown in FIG. 3, in the second embodiment, the curvature of the lid body end curved surface portion 27 on the rotation support portion 22 side of the curved surface of the outer periphery of the lid body 18 is larger than that of the first embodiment. Is formed.

  By increasing the curvature, as the lid 18 is opened, the gap b between the convex portion 25 and the notch 24 and the rotation trajectory at the end of the lid is increased. That is, in the rotation trajectory of the lid 18, the distance between the portion of the lid 18 closest to the convex portion 25 and the convex portion 25 is set so as to increase as the lid 18 is opened.

  As a result, even if a finger is placed in the gap, when the lid 18 is opened, the finger is further pinched and the finger is not damaged. Further, even when a finger is placed in the gap when the lid 18 is opened, the finger is pushed out from the gap when the lid 18 is closed, so that the lid can be opened and closed safely.

  As described above, in a simple configuration in which the curvature of the lid end curved surface portion is increased, the lid can be safely opened and closed without a finger being caught.

  As described above, the drum type washing machine according to the present invention does not have a complicated lid support structure, and an attendant such as a user or a child does not put a finger in the gap and can safely open and close the lid. Therefore, it can be applied to the use of other equipment having a lid that is rotatably supported.
