DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing lid for a washing machine which is provided on the upper surface of a washing machine main body so as to be freely opened and closed.

[0002]

2. Description of the Related Art Conventionally, the opening / closing lid of a washing machine of this type is shown in FIG.
And as shown in FIG. Hereinafter, the configuration will be described.

As shown in FIG. 5, an opening / closing lid 1 is provided on an upper surface of a washing machine main body 3 with one end pivotally supported by a pivot support 2 so as to be rotatable upward. The opening / closing lid 1 has two lids 1a and 1b that can be folded along an axis 4 substantially parallel to the shaft support 2.
It consists of. FIG. 6 shows an end of one lid 1a.
As shown in (a), a plurality of support shafts 5 that are cantilevered along the axis 4 are integrally formed, and the other lid 1b is
As shown in FIG. 6B, a bearing 7 holding the support shaft 5 is provided.
Are integrally formed at a position corresponding to the support shaft 5.

[0004] The two lids 1a and 1b are supported by a support shaft 5
Are penetrated through the bearing part 7 and are connected rotatably.

[0005]

Recently, fully automatic washing machines have been widely used in ordinary households. Although the convenience has been improved, there are many demands of users who want to check the flow of water and the movement of clothes during washing. Therefore, the lids 1a, 1
b must be made of a transparent material.

The materials of the lids 1a and 1b are inexpensive,
In many cases, an olefin resin such as polypropylene having excellent chemical resistance is used, but this material is somewhat cloudy, and there is a problem that sufficient transparency cannot be obtained as compared with, for example, a resin such as ABS.

Therefore, it is conceivable that the lids 1a and 1b are made of an inexpensive and highly transparent ABS resin.
Since the S resin has poor chemical resistance, there is a problem that the resin is cracked when stress is applied by opening and closing operations of the lids 1a and 1b in a state where a chemical such as a liquid detergent used for washing is attached.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and has excellent transparency, and is capable of opening and closing without cracking even when stress is applied by opening and closing operations of the lid in a state where a chemical such as a liquid detergent is attached. It is intended to provide a lid.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a hinge portion in which two transparent, substantially semi-disc-shaped windows made of ABS resin are formed in a central support made of polypropylene. And a frame made of polypropylene is arranged around the periphery of the window.

[0010] Thus, a wide area in the center is constituted by a window part made of ABS resin having excellent transparency, and a hinge part to which stress due to opening and closing work is easily applied and a peripheral part of the window part are polypropylene resin excellent in chemical resistance. Therefore, it is possible to obtain an opening / closing lid of a washing machine which has excellent transparency in a wide range and which does not break even when a chemical such as a liquid detergent used for washing adheres.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention according to claim 1 of the present invention is characterized in that two substantially semi-disc-shaped windows made of ABS resin and having transparency are rotatable. An ABS having a center support portion made of polypropylene constituting a hinge portion to be connected and a frame portion made of polypropylene arranged around the periphery of the window portion, and having excellent transparency over a wide center area.
It consists of a resin window, and the hinge and the periphery of the window, where stress due to opening and closing work is easy to apply, are made of polypropylene resin with excellent chemical resistance, so it has excellent transparency over a wide range and can be washed. It is possible to provide an opening / closing lid for a washing machine that does not crack even when chemicals such as a liquid detergent to be used adhere thereto.

According to a second aspect of the present invention, in the first aspect of the present invention, the frame portion includes a first frame portion made of polypropylene in which the periphery of the window portion is held by a claw fitting. The first frame portion is claw-fitted, and the other is configured with a window portion and a second frame portion made of polypropylene and claw-fitted, and the second frame portion is
The entire first frame portion and the claw fitting portion between the window portion and the first frame portion are covered, and a strong opening / closing lid can be easily formed only by the claw fitting. In addition, a complicated nail fitting portion can be hidden by the second frame portion, and an opening / closing lid of a washing machine excellent in design can be provided.
