Since 12 constitutes almost the entire surface of the lid body 3, it is possible to improve the designability of a flat feeling or a decorative feeling.

The front rear surface member 11 has a single-layer shape without an opening, and the rear rear surface member 13 has a double-layer shape, but has an opening 13a. Therefore, the front rear surface member 11 and the rear rear surface member 13 are formed. Have the same volume and are made of the same material, and thus have substantially the same weight.

On the other hand, since the relationship between the thickness t1 of the front top member 10 and the thickness t2 of the rear top member 12 is set to t1<t2, the weight of the front lid body 4 is larger than that of the rear lid body 5. Can be lightened. Accordingly, in the opening/closing operation of the lid body 3 performed by holding the handle portion 7, the weight applied to the handle portion 7 is reduced, and the operability can be improved.

As described above, in the present embodiment, the front side top surface member 10 and the rear side top surface member 12 that form the top surface portion of the lid body 3 are formed of a plate-shaped transparent resin material, and their back surfaces are also formed. In the washing machine main body 1, at the positions corresponding to the openings 13a formed in the rear back surface member at approximately the central portion of the rear top surface member 12, the ornamental parts 10c and 13c by silk printing are provided up to the ends. By forming the transparent central portion 12a in which the inside of the washing tub 9 is visible, a design with a sense of depth of the surface and a transparent and flat feeling are realized when the lid 3 is viewed in a closed state. At the same time, it is possible to improve the appearance quality at low cost and improve the careability.

Further, the thickness t1 of the front top member 10 is made smaller than the thickness t2 of the rear top member 12, so that when the lid 3 is opened and closed while holding the handle 7, the handle 7 can be used. It is possible to reduce the weight required for the operation and improve the operability.

As described above, the washing machine according to the present invention is configured such that the lid body has a shape without irregularities such as a fitting portion on the front surface side, and up to the end of the back surface of the transparent lid body upper surface member is decorated by printing or the like. Since the appearance and design can be improved by providing the portion, it can be applied to other uses of household electric appliances having a lid.
