Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a lid device for a washing machine that allows the inside of the washing machine, particularly the inside of the dehydration tank, to be seen through.

[Technical background of the invention]

For example, in recent years, two-tank washing machines have been provided that allow so-called rinsing and dehydration to be performed in the dehydration tank, and in these machines, a rinse water injector is installed below the outer lid of the dehydration tank. At the same time, the central part of the outer lid is made transparent so that the amount of water supplied to the water injector can be checked. Conventionally, the concrete structure of this outer lid is to form an opening in the center of the lid main body made of opaque resin, and to attach a see-through plate made of transparent resin to this opening, and to attach the see-through plate to its outer edge. The lid was fixed to the lid body using a mounting frame that could be pressed down.

[Problems with background technology]

However, the above configuration requires a large number of parts such as a see-through plate and a mounting frame in addition to the lid body, so a large number of expensive molds are required, and assembly is labor-intensive, resulting in overall manufacturing costs. It has the disadvantage of being bulky.

[Purpose of invention]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lid device for a washing machine that can be manufactured at low cost by reducing the number of parts.

[Summary of the idea]

The present invention is a device that opens and closes the spin-drying tank part of the main body of a washing machine, and the resin forming the lid body is made to have a property that the transparency varies depending on the wall thickness by adding a pigment to the transparent resin. A hinge arm for pivotally supporting the lid body on the washing machine body; a transparent portion that allows the interior of the dehydration tank to be seen through by molding a predetermined area of the lid body to be thinner than other areas; By integrating the transparent part with a thick reinforcing frame located around the transparent part, it is possible to eliminate the need for a separate transparent plate, which was previously required, and at the same time, there are concerns about the strength of the lid. This feature is unique in that it is designed to prevent this from occurring.

[Example of idea]

An embodiment in which the present invention is applied to a two-tub washing machine will be described below with reference to the drawings. Reference numeral 1 denotes an outer box in which a washing tub 2 and a dehydrating tub 3 are installed, and an operation box 4 is erected at the rear of the upper surface. The operation box 4 is provided with a water supply port body 5 for connecting a water supply hose, and a water supply switching device (not shown) for selectively supplying water from the water supply hose to the washing tub 2 side and the dehydration tub 3 side. It is set up. Reference numeral 6 denotes a running water case disposed below the operation box 4, which guides water from the water supply switching device to the upper part of the dehydration tank 3. Reference numeral 7 denotes a water injector that is openable and closable at the top opening of the dehydration tank 3, which receives water from the water case 6 and causes it to flow down from the water inlet 7a to the dehydration basket 8 side in the dehydration tank 3. As shown in FIG. 4, the water injector 7 has a flat container shape, and a stepped portion 7b is formed in the rear half of the bottom.
The amount of water supplied can be determined by observing which step of the stepped portion 7b is submerged by the surface of the water supplied inside. Now, 9 is dehydration tank 3
This side lid device is provided above the water injector 7 so as to be able to open and close the top opening of the dehydration tank 3. The specific structure will be described below with reference to FIGS. 5 and 6. Reference numeral 10 is a lid body having a generally rectangular shape. First, this is a transparent resin made by mixing a small amount of pigment in a transparent acrylic resin in advance. It is formed by integral molding of a translucent resin that has been subjected to a reduction treatment so that its transparency varies depending on its thickness. The approximately central rectangular area of the lid body 10 is formed to have a wall thickness of, for example, approximately 0.5 to 1.0 mm, and the other areas are formed to have a wall thickness of, for example, approximately 2.0 to 3.0 mm. The rectangular area is configured to be a see-through portion 11 with sufficiently high transparency, and the other areas are configured to be almost opaque. Reference numeral 12 denotes a thick reinforcing frame portion integrally provided on the lower surface of the lid body 10 along the outer peripheral edge of the transparent portion 11;
A storage groove 13 is formed in a portion of the upper surface along the reinforcing frame portion 12, and a plurality of attachment holes 14 are formed through the bottom of the storage groove 13. Reference numeral 15 denotes a decorative frame serving as a frame member for separating the see-through section 11 from other areas, and this frame has a rectangular frame shape corresponding to the storage groove 13 and integrally has a plurality of mounting claws 16 for easy installation. By elastically engaging the claws 16 with the mounting holes 14, the lid body 10 is fixed to the lid body 10 while being housed in the housing groove 13. 17 is the lid body 1
This is a hinge arm integrally provided on the rear edge of 0, and has a hinge pin 17a protruding from this, which pivotally connects the lid device 9 to the operation box 4 so as to be rotatable. Reference numeral 18 designates an edge wall integrally molded downward from the outer peripheral edge of the lid main body 10, and reference numeral 19 designates a large number of reinforcing ribs integrally molded on the lower surface of the lid main body 10 so as to be connected to the edge wall 18. On the other hand, 20 is a lid device on the side of the washing tub 2, which, like the lid device 9 on the side of the dehydration tank 3, is made of a transparent resin that has been treated with a transparent resin mixed with a small amount of pigment to reduce its transparency. The lid body 21 is formed by forming a rectangular area at the approximate center of the lid body 21 thinly to form the see-through portion 22, and by forming the other areas thickly. It is designed to be almost opaque. Also, a decorative frame 23 serving as a partitioning frame member is attached to the outer peripheral edge of the transparent portion 22 with a structure similar to that of the lid device 9 for the dehydration tank 3, and the lid body 21
An edge wall portion 24 is integrally formed on the outer peripheral edge of the lid body 21, and reinforcing ribs 25 are integrally formed on the lower surface of the lid body 21. In addition, 26
is a hook portion integrally protruding from the lower surface of the lid body 21.

Now, in the above configuration, when dehydrating and rinsing is performed in the dehydrating tank 3, the water supply switching device is switched to the dehydrating tank 3 side and water from the tap is supplied to the water injector 7 via the running water case 6. At this time, if the amount of water supplied to the water injector 7 is insufficient, dehydration and rinsing cannot be performed properly, and if the amount of water supplied is excessive, water overflows from the water injector 7 and is wasted. Therefore, in the case of this embodiment, the see-through part 11 of the lid device 9 on the side of the dehydration tank 3
Since the inside of the water injector 7 can be seen through the water injector 7, the amount of water supplied can be adjusted so that the water level in the water injector 7 is at a predetermined position. On the other hand, when washing is performed in the washing tub 2, if the lid device 20 is attached to the washing tub 2, it is possible to prevent the floor surface from getting wet due to water splashing. Since the inside of the washing tub 2 can be seen through the see-through section 22 of 20, the progress of washing can be checked.

According to this embodiment, since the transparent parts 11 and 22 of the lid devices 9 and 20 are integrally molded with the lid bodies 10 and 21 from the same material, the conventional transparent plates and their mounting members are completely unnecessary. You can get used to it. Therefore, not only can the number of expensive molds be reduced, but also the troublesome process of assembling separate parts such as a see-through plate to form the lid body can be omitted, resulting in a significant reduction in manufacturing costs overall. can be achieved. In addition, especially if the reinforcing frames 12, 12 are integrally molded on the outer peripheral edges of the transparent parts 11, 22 as in this embodiment, the transparent parts 11, 2
2 is thin and cantilever-supported on the main body of the washing machine via the hinge arm 17, it is possible to eliminate concerns about strength, and furthermore, the transparent parts 11 and 22 are If the decorative frames 15 and 23 are attached to the outer peripheral edge, the transparent part 1
1 and 22 are clearly separated, which is even more convenient.

In the above example, a translucent resin was used which had been treated to lower its transparency by mixing a pigment in advance into the transparent resin. It may also be mixed in to lower the transparency. Furthermore, the present invention can be implemented with various modifications, such as the frame member may be a thin tape-like member.

[Effect of idea]

In summary, the present invention is a device that opens and closes the dehydration tank part of a washing machine main body, and the resin forming the lid body is made to have a property in which the transparency varies depending on the wall thickness by adding a pigment to the transparent resin. In addition, a hinge arm for pivotally supporting the lid body on the washing machine body, and a see-through portion that allows the inside of the dehydration tank to be seen through by forming a predetermined area of the lid body to be thinner than other areas. By integrating the transparent part with a thick reinforcing frame located around the transparent part, it is possible to eliminate the need for a separate transparent plate, which was required in the past, and to reduce costs. However, the weak point in strength due to the see-through part is compensated for by the reinforcing frame part, so there is no concern about the strength of the lid.
