Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a speaker mounting device for a washing machine having a function of audibly announcing the progress status of a washing process.

Structure of a conventional example and its problems Figures P, 2, and 3 show the structure of a conventional washing machine, where 1 is a washing rack, and 2 is a rotary blade rotatably installed at the bottom of the washing tub. , 3 is a drive unit that drives the rotary blades 2 and the like. Reference numeral 4 denotes a main body, which has a top plate 5 on its upper part, and an operation plate etc. are provided on the front surface of this top plate 6.

A control board 7 and the like for controlling the drive unit 3 and the like of the washing machine is fixed to the top back plate 8 and arranged inside the rear part of the top plate 6.
This top plate back plate 8 is screwed to the lower part of the top plate 5.

On the inside of the rear surface of the top plate 6, a speaker 10 is sandwiched between a speaker mounting plate 9 (hereinafter simply referred to as the mounting plate) and the rear surface of the top plate 6.

The top plate 6 has an inwardly convex shape 1 at which the speaker 10 is attached.
1, and at least one bin 12 is provided at the bottom thereof. The lower part of the mounting plate 9 is bent toward the rear side of the top plate 5, and a hole 13 is bored in the bent portion 9a, through which a bottle 12 provided integrally or integrally with the top plate 5 is inserted. 14 is a hole provided in the mounting plate 9 into which the coil portion 15 of the speaker 10 is inserted.

By providing the bent portion 9a of the mounting plate 9 with a cut-out portion 9b, the height h of the mounting plate 9 can be adjusted to the distance Ml from the inner upper surface of the top plate 5 to the top back plate 8. are equal. 1
6 is a rig provided on one inner surface of the top plate 5, and this lip 1
The distance at the rear inner surface 5ai of the top plate [] is 1° from the speaker 1o! It is slightly shorter than the sum of the length A and the thickness T of the mounting plate 9 [7].

When assembling, the speaker 1o is sandwiched between the rear inner surface 5a of the top plate 5 and the mounting plate 90, and in this state, the bottle 12 provided on the top plate 5 is inserted into the hole 13 of the bent part 9a at the bottom of the mounting plate 9. At the same time, insert the mounting plate 9 so that the upper part of the mounting plate 9 is aligned with the top plate 5 side of the above-mentioned 7'16.

In this way, according to the conventional mounting structure of the speaker 1o,
At the time of assembly, insert the bottle 12 provided on the top plate 5 into the hole 13 of the folded part 9a, and at the same time insert the upper part of the mounting plate 9 into the hole 13.
It is necessary to simultaneously insert the speaker 16 into the top plate side, and as mentioned above, the distance between the lip 16 and the rear inner surface 5a of the top plate 5 is determined by the thickness A of the speaker 10 and the mounting plate 4. Since it is smaller than the sum of the plate thicknesses T, it was necessary to perform an extremely difficult assembly operation in which the upper part of the mounting plate 9 was artificially bent and pushed into the top plate 5 side of the rift 16. Since the speaker 10 contacts the lip 16 in a bent state, that is, in a bent state so as to press the speaker 10 against the rear surface 5a of the top plate, a deflection force F by the mounting plate 9 acts on the rig 16 on a daily basis. On the other hand, the cross-sectional shape of the lip 16 is
As shown in FIG. 4, since the rig 16 has a very small section modulus, there is a risk that the base of the rig 16 may break or become white during long-term use.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems, provide a structure that allows for easy installation of speakers, and prevents breakage of the rig.

Structure of the Invention In order to achieve the above object, the present invention provides a mounting plate to sandwich the speaker between the rear inner surface of the top plate, and a mounting plate that is mounted on the top plate in a direction perpendicular to the rear inner surface. at least one glue located on the rear inner surface side of the lip where one end side of the mounting plate is rotationally locked with the other end side as a fulcrum, the one end side of the mounting plate is guided. The guide surface has a radius of curvature equal to 11 times the height of the mounting plate. Due to the guiding action of the speaker, the speaker can be mounted easily and without bending the lip.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 5 to 10. Note that in this figure, the same reference numerals as in FIGS. 1 to 3 indicate the same members, and therefore the description thereof will be omitted. In the figure, reference numeral 17 denotes at least one (two in the embodiment) Bengyo lip provided perpendicularly to the rear inner surface 5a of the top plate 6, and from the end 17a of this lip 17 on the rear inner surface 5a side The distance to 5a is set to be slightly shorter than the sum of the thickness A of the speaker 1o and the thickness T of the mounting plate 9.

A sloped part 17b facing the front of the top plate 5 is provided at the lower part of the end part 17a of the rig 17, and furthermore, at the lower part thereof,
The mounting plate 9 has a guide surface 17c having a radius of curvature equivalent to the height h of the mounting plate 9.
The distance between the continuous portion E with 7b and the tip of the bottle 12 is made approximately equal to the height h of the additional issue board 9.

Here, when assembling, place the speaker 1 in the mounting plate 90 hole 13.
After the mounting plate 9 and the speaker 10 are put into a unit state by passing the coil part 15 of the top plate 5 through the coil part 15 of the top plate Pass the pin 12 through the hole 13 of the mounting plate 9. At this time, the upper part of the mounting plate 9 is placed on the rib 17, and the mounting plate 9 is placed on the pin 12 along the guide surface 17c.
By rotating it in the direction of the arrow B and pushing it up in the direction of the arrow B, the end 1 is moved along the slope part 17b.
Insert and lock on the 7a side.

In this manner, when assembling the speaker 10 and the mounting plate 9 as a unit, by rotating the speaker 10 and the mounting plate 9 in the direction of the arrow around the pin 12, the end 17 of the ring '17 on the rear inner surface 6a side, the can be easily inserted into. In particular, there is no need to artificially bend the upper part of the mounting plate 9 for insertion as in the past, and the mounting plate 9 is inserted from below in the direction of arrow B using the guide surface 17c and sloped part 17b of the rear end as guides. The mounting plate 9 can be inserted and fixed very easily by simply pushing it.

In addition, since the cross-sectional shape of the lip 17 has a considerably large section modulus as shown in FIG. There is no fear that the root portion of the 17 will break.

Effects of the Invention As described above, according to the present invention, the mounting plate can be easily constructed by improving the direction of the lip provided on the large plate with respect to the rear inner surface of the top plate, and the shape of the lip. , speakers, etc. can be set very easily by rotating operations, and it is also effective in preventing abnormalities such as breakage at the base of the lip.
