When the door 5 is moved in the opening direction (upward in FIG. 1), the fourth plate 21 is rotated about the support shaft 7 in the direction of arrow B in accordance with the movement of the door 5. Based on the rotation of the fourth plate 21, the projection member 23 pushes down the slide groove 22 in the direction of arrow C, whereby the third plate 20 is rotated around the support shaft 6 in the direction of arrow A. Become. As described above, the relationship between the fourth plate 21 and the third plate 20 is such that the cooperation of the projection member 23 and the slide groove 22 allows the other to be simultaneously rotated in conjunction with the rotation of one. It exists. When the door 5 is further opened, the third plate 20 is rotated in the direction of the arrow A in response to the rotation of the fourth plate 21 in the direction of the arrow B. As shown in FIG.
The first protrusion member 23 contacts the left end of the slide groove 22 of the third plate. As described above, when each of the doors 4 and 5 is being opened, the projecting member 23 moves in the sliding groove 22 and comes into contact with the end on the opposite side of the sliding groove 22.

When the door 5 is further opened from the state shown in FIG. 10B, the fourth plate 21 is further rotated in the direction of arrow B, and the third plate 20 is further rotated in the direction of arrow A. Thereby, the projection member 23 of the fourth plate 21
Pushes down the sliding groove 22 of the third plate 20 in the direction of arrow C, and finally, as shown in FIG.
The rotation of each of the fourth plate 21 and the third plate 20 is stopped in a state where the one protrusion member 23 is in contact with the left end of the sliding groove 22 of the third plate 20. At this time, the doors 4, 5
Are held open as shown in FIG. Thereafter, the dishes are stored in the washing room 10 of the dishwasher 1, or the dishes are taken out of the washing room 10.

On the other hand, when the dishes are washed and rinsed through the washing nozzle 11 and the rinsing nozzle 12, the openable doors 4, 5 which are open as described above are closed. When the doors 4 and 5 are closed in this manner, the fourth plate 21, the third plate 20, and
Each of the projection members 23 and the sliding grooves 22 performs an operation reverse to the above-described operation, and shifts from the state shown in FIG.
The state shown in FIG. 10A is maintained through the state shown in FIG. Thus, even when the respective doors 4 and 5 are closed, the other doors are simultaneously closed in conjunction with the operation of closing one of the doors.

As described above, in the second opening / closing mechanism, the support shafts 6 and 7 are fixed to the top hood 3 constituting a part of the main body 2 of the cleaning machine by disposing them at positions separated from each other on the horizontal line L. At the same time, the third plate 20 is supported rotatably around the support shaft 6, and the fourth plate 21 is supported rotatably around the support shaft 7.

It is configured to perform simultaneous opening and closing. Therefore, similarly to the first opening / closing mechanism, unlike the door opening / closing mechanism in the conventional dishwasher, each of the support shafts 6 and 7 does not need to have the same axis at all. It can be flexibly selected on the horizontal line L. Thereby, since there is almost no restriction on the configuration of the simultaneous opening / closing mechanism of the doors 4, 5, the simultaneous opening / closing of the doors 4 and 5 by a simple mechanism without providing a complicated structure such as a gear mechanism. An opening and closing mechanism can be achieved.

In the second opening / closing mechanism, basically, a simultaneous opening / closing mechanism for each of the opening / closing doors 4, 5 can be simply constituted by the support shafts 6, 7, the third plate 20, and the fourth plate 21. Therefore, it is possible to obtain a low-cost door opening / closing mechanism without reducing the number of components and requiring strict processing accuracy and assembly accuracy. It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the spirit of the present invention.
