Another object of the present invention is to provide a washing machine in which the engagement claws are suppressed from being seen through.

[0006]

SUMMARY OF THE INVENTION A washing machine according to the present invention comprises a machine frame in which a washing tub is provided and a machine frame formed on an upper surface of the machine frame.
An input port for inputting clothes into the washing tub and a lid for opening and closing the input port are provided, and the lid is rotatably supported at a rear end on a rear side of the input port. A first lid, a second lid having a rear end rotatably connected to a front end of the first lid, an opening formed in the second lid, and an opening formed in the second lid. , A stand-up wall integrally formed on the periphery of the see-through window, an engagement hole formed in the stand-up wall, and the engagement hole integrally formed on the periphery of the opening. The engaging claw has a triangular cross section in which the inclined surface is located on the upper side, and the upper surface of the engaging hole is inclined so as to be along the inclined surface. It is characterized by the following.

Further, the upper surface of the engagement hole is substantially parallel to the inclined surface and is close to the inclined surface.

Further, the upper surface of the engagement hole is a diffuse reflection surface.

[0009]

The see-through window is mounted by engaging the engaging claws on the peripheral edge of the opening of the second lid with the engaging holes in the vertical wall of the see-through window. In this case, the upper side surface of the engaging hole is inclined along the upper inclined surface of the engaging claw, and is close to the inclined surface in a substantially parallel state. That is, the upper side surface of the engaging hole is lowered to the lower side as compared with the conventional case, and the dimension from the outer surface of the see-through window body to the engaging hole is not much different from the vertical dimension of the see-through window body at the place where there is no engaging hole. It is in a state.

Accordingly, the peripheral portion of the see-through window body is moved outward (upper side).
When viewed from above, there is almost no difference in shading between the location with the engagement hole and the location without the engagement hole. Further, since the portion having the engaging hole is not felt faint, the engaging claw in the engaging hole is not clearly seen through. Since the upper surface of the engagement hole is a diffuse reflection surface, the engagement claw is more difficult to see through.

[0011]

FIG. 1 shows the appearance of a fully automatic washing machine according to an embodiment of the present invention. 1 is a machine frame in which a washing tub (not shown) is installed,
On the upper surface of the machine frame 1, an input port (not shown) for inputting clothes into the washing tub is formed.

Reference numeral 2 denotes a lid for opening and closing the inlet. In the lid 2, reference numeral 3 denotes a first lid, and 4 denotes a second lid. The lids 3, 4 are all made of resin. The rear end 5 of the first lid 3 is rotatably supported on the upper surface of the machine frame at the rear side of the inlet, and the rear end 6 of the second lid 4
Is rotatably connected to the front end of the first lid 3.

When the user puts his / her hand on a hand-holding portion (described later) of the second cover portion 4 and pushes the second cover portion 4 backward, the first cover portion 3 rotates upward about the rear end 5. With the second
The lid 4 pivots downward about the rear end 6 and, as a result,
The lid 2 has a broken shape and reaches the rear side of the inlet, and opens the inlet.

Hereinafter, details of the vicinity of the second lid 4 will be described with reference to FIGS. Reference numeral 7 denotes a substantially triangular opening formed near the center of the second lid 4, and reference numeral 8 denotes a blackish, concave, resin-made transparent window that covers the opening 7 from the outside (upper side) of the second lid 4. With the body, the inside of the washing tub can be confirmed through the see-through window 8. The specific material of the see-through window 8 is AS
(Acrylonitrile styrene) resin.

Reference numeral 9 denotes a front projecting portion 10 of the see-through window 8.
A linear projection that is long on the left and right,
Reference numeral 1 denotes a first linear groove that is formed in the second lid portion 4 in front of the opening 7 and that is fitted with the protrusion 9.
2 is integrally formed on the lower surface of the front projecting portion 10 of the see-through window body 8 similarly to the above-mentioned projection 9 and has a front peripheral portion 1 of the opening 7.
3 is a contact portion that is long in the left and right directions. The projection 9 and the contact portion 12 reinforce the see-through window 8, and the first groove 11 reinforces the second lid 4.

The rear peripheral portion 14 of the see-through window body 8 except for the front side portion has a rear peripheral portion 1 of the opening 7 at six locations marked with # marks.
5 is attached. This structure will be described with reference to FIG. 8 in particular. Reference numeral 16 denotes a first claw (engaging claw) integrally formed with the rear peripheral portion 15 of the opening 7, and reference numeral 17 denotes a rear peripheral edge of the see-through window 8. A standing piece or standing wall 18 integrally formed with the portion 14 is an engagement hole formed in the standing wall 17 and engaged with the first claw 16.

The first claw 16 has a triangular cross section in which the inclined surface 16a is located on the upper side.
a is inclined so as to be along the inclined surface 16a. The upper side surface 18a of the engagement hole 18 is substantially parallel to the inclined surface 16a and is close to the inclined surface 16a.
The upper surface 18a of the engagement hole 18 is rough and irregularly reflective.

In this case, the upper surface 18a of the engaging hole 18 is lower than the conventional one, and the maximum dimension A from the outer surface of the see-through window 8 to the engaging hole 18 is a portion where the engaging hole 18 is not provided. Is not much different from the vertical dimension B of the see-through window body 8.

Therefore, when the periphery of the see-through window 8 is viewed from the outside (upper side) as indicated by the arrow E, a difference in shading is hardly perceived between the portion where the engagement hole 18 is provided and the portion where the engagement hole 18 is not provided. In addition, since the portion where the engaging hole 18 is located does not feel light, the first claw 16 in the engaging hole does not clearly appear. Since the upper surface 18a of the engagement hole 18 is a diffuse reflection surface, the engagement claw 16 is more difficult to see through.

Further, also when the peripheral portion of the see-through window 8 is viewed obliquely from above as shown by the arrow F, the upper surface 18a of the engaging hole covers the first claw 16 and the upper surface 18a. Is a diffuse reflection surface, the first claw 16 is difficult to see through.

Reference numeral 19 denotes a resin-made handle for opening and closing the cover 2. The handle 19 sandwiches the front side of the see-through window 8 together with the front side of the second cover 4. As such, it is disposed on the front side of the second lid 4. When the handle 19 is on the front side and is as close to the user as possible, the opening and closing operation of the lid 2 is easy.

The handle 19 is attached and fixed to the front side of the second cover 4 at six places of & mark and five places of mark.

The structure of the & mark portion will be described in particular with reference to FIG. 7. Reference numeral 20 denotes a second claw integrally formed on the lower surface of the handle 19, and 21 denotes a front side of the second lid 4. The second groove 21 is bent at two places near the end of the first groove 11. Reference numeral 22 denotes an engagement hole formed in one side wall of the second groove 21, that is, a front side wall 23, in which the second claw 20 is engaged.
Claw 2 integrally formed with the lower surface of the second claw 20 and the second claw 20
The first rib 24 restricts the deflection of the first rib.
Crosses the inside of the second groove 21 and has a rear end portion in the second groove 2.
The other side wall, that is, the rear side wall 25 is in a separated state.

Next, the structure of the mark will be described with reference to FIG. 6 in particular. Reference numeral 26 denotes a third claw integrally formed on the front end of the second lid 4, and 27 denotes a front end of the handle 19. A piece 28 integrally formed on the lower surface is an engagement hole formed on the piece 27 and engaged with the third claw 26.

Also, in FIG.
The second rib 29 integrally formed on the lower surface of the
Crosses the inside of the second groove 21 and has a rear end
The groove 21 is in contact with the other side wall, that is, the rear side wall 25. As shown in FIG. 5, the second ribs 29 are provided at lateral positions of the second claws 20, that is, at five places between the second claws 20.

Next, a procedure for mounting the see-through window 8 and the handle 19 on the second lid 4 will be described.

First, the transparent window body 8 is brought to the opening 7, and the rear peripheral portion 14 of the transparent window body 8 is engaged with the first claw 16 in the engagement hole 18, whereby the second lid is opened. Attach to part 4. In this case, the engagement position of the first claw 16 is 6 of the # mark.
Only the location is sufficient, and the number of locations is small, and mounting of the see-through window body 8 is easy.

At this time, on the front side of the see-through window 8, the projection 9 is fitted into the first groove 11 of the second lid 4, and the contact portion 12 is fitted to the front peripheral portion 13 of the opening 7. Abut,
The rattling before and after the see-through window body 8 is prevented.

Then, with the transparent window body 8 attached in this manner, the handle 19 is connected to the plurality of second claws 20 and the third
The claw 26 is fixedly attached to the second lid portion 4 by engaging with the engagement holes 22 and 28, respectively. With the above, the mounting of the see-through window 8 and the handle 19 is completed.

In this case, the front side of the see-through window 8 is pressed against the second lid 4 so as to be sandwiched between the handle 19 and the second lid 4. As a result, the see-through window 8 is
In addition to preventing back-and-forth rattling as described above, by preventing vertical movement, disengagement of the first claw 16 at the rear peripheral portion 14 is suppressed, and the first window 16 of the see-through window 8 is The attachment to the lid 2 is ensured.

The projection 9 is pressed against the first groove 11 by pressing the front side of the see-through window 8 against the second lid 4. Therefore, even if the vicinity of the first groove 11 of the second lid portion 4 is curved, it is corrected.

Further, the bending of the second claw 20 is restricted by the first rib 24. Accordingly, the engagement of the second claw 20 with the engagement hole 22 causes the handhold portion 19 to be bent with a considerable force. This is performed by pressing the second claw 20 against the first lid 24 by pressing the second claw 20 against the second lid portion 4, but once the engagement is performed,
Since the second claw 20 does not bend easily due to the presence of the first rib 24, it does not undesirably come off.

Further, the rear end of the second rib 29 is brought into contact with the rear side wall 25 of the second groove 21, whereby a large force is applied to the handle 19 when the cover is opened and closed. Even if the second claw 20 attempts to disengage, the rear end of the second rib 29 beside the second claw 20 contacts the rear side wall 25 of the second groove 21 located in the disengagement direction. It is blocked by contact. Therefore, undesired detachment of the second claw 20 is also prevented at this point.

Further, since the third claw 26 is located at the front end of the second lid portion 4 and engages with the engagement hole 28 at the front end of the handle 19, the front end of the handle 19 is It adheres tightly to the front end of the second lid 4, and no gap is formed there.

[0035]

According to the washing machine of the present invention, in the configuration in which the transparent window for confirming the inside of the washing tub is provided on the lid that closes the clothes slot, when the peripheral edge of the transparent window is viewed from the outside. It is possible to prevent the user from feeling uncomfortable due to the difference in shading, and also to prevent the engaging claw from being seen through.

Further, in order to avoid the above-mentioned difference in shading,
It is not necessary to shorten the distance from the outer surface of the see-through window body at a place where there is no engaging hole with which the engaging claw is engaged, and therefore the strength of the see-through window body can be sufficiently maintained.
