Therefore, since the opening of the dishwasher main body 2 is largely opened by both doors, particularly the upper door 10, the user can place the dishes in the dish basket 45.
It can be stored easily.

When the user closes the lower door 11 from the open state of the opening 9 of the dishwasher main body 2 by the both doors 10 and 11 as described above, one end of the cable wire 63 is attached to the lower door 11. It is pulled downward by the connecting plate 61, and in conjunction with this, the tip end portion of the lever 60 of the upper door 10 is pulled inward of the dishwasher main body 2.

In this way, when the tip of the lever 60 comes to be pulled inward of the dishwasher main body 2, the lever 60 is pulled.
Comes to rotate around the fulcrum roller 64,
The turning force of the lever 60 acts on the upper door 10. At this time, the first guide portion 65a of the guide rail 65
Is directed in the pulling direction by the cable wire 63 and guides the tip end portion of the lever 60 in a substantially tangential direction around the fulcrum roller 64, so that the upper door 10 is closed by a small closing operation force on the lower door 11. It can be rotated from the open position.

When the lower door 11 is further closed, the tip portion of the lever 60 is correspondingly moved to the guide rail 6
The second guide portion 65b of No. 5 is guided.
At this time, the lever 60 is separated from the fulcrum roller 64. In addition, the second guide portion 6 of the guide rail 65
Since 5b is oriented in a tilt direction (downward from the horizontal direction) opposite to the pulling direction of the cable wire 63, the amount of movement of the tip of the lever 60 guided by the guide rail 65 is determined by the cable wire 63. Will be larger than the quantity. As a result, the amount of rotation of the upper door 10 becomes larger than that when the tip end portion of the lever 60 is pulled in the pulling direction by the cable wire 63, and the upper door 1 is as much as that.
The rotation amount of 0 can be increased, and the upper door 10 can be changed to the lower door 1
It can rotate to catch up with 1.

When the lower door 11 is further closed, the tip of the lever 60 is moved to the third guide portion 65c of the guide rail 65.
Will be guided by. At this time, since the third guide portion 65c of the guide rail 65 is oriented in the same direction as the guide direction of the first guide portion 65a (above the horizontal direction), it is guided by the third guide portion 65c. Lever 60
The amount of movement of the tip of the cable is approximately the same as the amount of pulling by the cable wire 63. As a result, the amount of rotation of the upper door 10 becomes substantially equal to the amount of rotation of the lower door 11, so that the upper door 10 can be rotated in synchronization with the lower door 11.

By the way, the length of the upper door 10 is the lower door 11
Since the length of the upper door 10 is set shorter than that of the lower door 11, when the upper door 10 is closed in synchronization with the lower door 11, the tip of the upper door 10 is rotated in a state of being positioned closer to the closing side than the tip of the lower door 11. Therefore, the upper door 10 can be closed earlier than the lower door 11.

Moreover, the length dimension of the upper door 10 on the front surface side is set shorter than the length dimension of the rear surface side, and the length dimension of the lower door 11 on the front surface side is smaller than that on the back surface side. Since it is set to be long, the upper door 10 is pressed by the lower door 11 when the lower door 11 is in the closed position. Therefore, when the upper door 10 and the lower door 11 are located at the closed position and the lower door 11 is locked, the upper door 10 is also locked.

When the upper door 10 and the lower door 11 of the dishwasher main body 2 are closed as described above, the user operates the elevating lever 39 upward. Then, a signal indicating that the elevating lever 39 has been operated upward is output to the control device of the elevating device 14, so that the elevating device 1
8 is rotated in the winding direction. As a result, the pulley 20 rotates to wind the two belts 21 at the same time.
The elevating case 15 stretched over 1 and thus the dishwasher main body 2 ascend in a horizontal state.
