DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In recent years, particularly in order to eliminate the entanglement of clothes in the clothes, the reverse water flow time period for washing is shortened, and washing methods for agitating clothes in small steps are becoming mainstream. In addition, as the capacity of laundry increases, the ratio of clothes to the standard amount of water in the washing layer, that is, the bath ratio, must be made smaller and smaller in order to enable compactness, and the standard water level line of the washing tub also rises upward. It tended to be raised.

One of the disadvantages in such a situation is that when it is turned upside down, the agitated water and clothing alternately collide with each other, resulting in what is called splashed water, and the tendency to jump out of the tank increases. When installing a washing machine indoors, the floor surface may get wet and may be mistaken for a water leak accident.

Also, when the standard water level line is set at a high position, especially when one sheet is operated with the amount of water up to the standard water level line, the water rises along the side wall of the washing tub, forming a squirrel-like shape and a large amount of water. , It will jump out of the tank.

Therefore, to prevent these water from scattering, it is sufficient to place a washing lid to cover the upper opening of the washing tub and wash.
It is inefficient to put the laundry lid on each time or take it out and hang it on the handle, etc., and it is desired that the lid itself be rotatably supported. FIG. 6 shows a lid shaft support device that has been conventionally used.

In FIG. 6 (a), the shaft 11 is projected outward at a position close to the panel box 7 on both side surfaces of the laundry lid 10, and the upper portion of the rear surface of the laundry lid 10 facing the front wall of the panel box 7 is substantially formed. It is formed by forming a circular arc portion 12 and chamfering so that it fits within the same turning radius with respect to the turning locus of the shaft 11, and with such a structure, it is suitable for a thin lid, so-called a lid with a low total height, In the washing lid 13 having a high lid as shown in FIG. 6 (b), the arcuate portion is large, so that the shaft fulcrum has to be provided in the panel box, and a part of the front wall of the panel box is provided via the hinge portion 14. Must be pivoted as the cutout portion 15, and a biasing force is required for the hinge portion 14 by a spring or the like (not shown) for holding when the lid is opened. Therefore, in such a structure, a large storage space for the hinge 15 is required in the panel box, the bearing structure is complicated, and a waterproof structure in the panel box is also required from the notch 15. I had a problem.

The present invention solves such a problem, and can pivot the laundry lid without providing a shaft fulcrum in the panel box and without requiring a tall laundry lid or a substantially arcuate portion. The purpose is to do so.

Means for Solving the Problems In order to achieve the above-mentioned object, the first means of the present invention is to arrange a panel box on a washing lid that covers the upper opening of the washing tub, and to extend the guide in the front-rear direction. One of the groove and the rotating shaft is provided at the rear portion of the laundry lid, and the other is provided in the main body of the washing machine to guide the rotating shaft to the guide groove, so that the laundry lid can be freely detachably rotated. The guide groove is provided with an insertion portion that is inclined forward of the position of the rotating shaft when the laundry lid is opened.

Further, a second means of the present invention is the same as the first means, wherein the front wall portion of the panel box and the back wall of the laundry lid are rotation guide portions.

Effect of the Invention With the above-described structure, the present invention allows the laundry lid having a high overall height to pivot about the laundry lid only by forming the guide groove so that the lid can be freely rotated. It is not necessary to provide a part or the like, and the configuration can be simplified. Further, when the laundry lid is strongly pushed backward, the laundry lid can be detached so as not to be damaged.

Embodiment FIG. 1 is a vertical sectional view of an embodiment of a lid device for a washing machine according to the present invention, FIG. 2 is a vertical sectional view showing a turning locus of a washing lid according to the present invention, and FIG. 3 is a laundry according to the present invention. FIG. 4 is a cross-sectional view of the lid, and FIG. 4 is an exploded perspective view of the lid device of the present invention.

It should be noted that, in the figure, the description of the same parts as those of the conventional example will be omitted.

A water supply receiver 16 and a cover 17 are mounted inside the panel box 7, and a water return plate 18 is mounted around the opening of the washing tub 2. Reference numeral 19 denotes a washing lid, and a rotary shaft 21 is formed at a part of a tip extending from a part of the rear surface wall 20 so as to project outwardly from the side surface. Reference numeral 22 is a reinforcing rib provided near the rotating shaft 21.

Reference numeral 23 is a lid holding member formed integrally with the water return plate 18 and provided in the vicinity of the panel box 7, and the washing lid 19 is provided.
A guide groove 24 is provided so as to face the rotary shaft 21. twenty five
Is to fit with the projection 26 of the water return plate 18 in the groove. On the other hand, the other of the lid holding members 23 may be provided on a part of the water return plate 18 on the opposite side or integrally with a part of a dehydration hatch (not shown) so as to cover the opening of the dehydration tank 3. Good. 27 is an insertion part for setting the laundry lid 19.

 The operation of the lid device of the present invention will be specifically described.

In the above structure, the rotary shaft of the laundry lid 19 is arranged at a position near the outside of the panel box 7, and the rotary shaft is gradually guided by the guide groove, whereby the rotary fulcrum is gradually changed and the compact structure is achieved. It is possible to rotate in a wide space.
Further, by positioning the rotating shaft 21 below the washing tub 2, the upper wall of the washing tub 2 is brought into contact with the rear wall of the laundry lid and the shaft is held by the guide groove 24 when opened. Therefore, it is not necessary to hold and fix the laundry lid 19 using a spring or the like. Further, by providing the insertion portion, the laundry lid 19 can be easily set even after the panel box or the like is assembled, and the guide groove 24 is formed so as to be inclined forward of the position of the rotating shaft 21 when the laundry lid 19 is opened. When the laundry lid 19 is strongly pushed rearward, the rotating shaft 21 is disengaged from the guide groove 24 to prevent the laundry lid 19 and the like from being damaged. Can be detachable.

On the other hand, since the guide groove 24 is formed in a substantially arc shape so as to slide and guide the rear wall portion of the washing lid 19 and the front wall of the panel box, the turning operation becomes easier.

The guide groove 24 may be provided on the side wall side of the laundry lid 19, and the same effect can be obtained by installing the guide groove 24 above the upper end surface of the washing tub, for example, in a part of the panel box. .

EFFECTS OF THE INVENTION As is clear from the above embodiments, according to the present invention, the guide groove is used to guide the rotation, so that the shaft holding portion can be compactly formed with a simple structure, and even a washing lid with a high overall height can be rotated. There is no chamfering that matches the motion trajectory, and no complicated bearing structure such as a hinge is required. Further, the rotating shaft is guided in the guide groove so that the laundry lid can be freely attached and detached, and the guide groove is inserted in the guide groove forward of the position of the rotating shaft when the laundry lid is opened. Therefore, it is possible to provide a lid device for a washing machine in which the laundry lid is detachable so as not to be damaged when the laundry lid is strongly pushed backward.
