According to a first aspect of the present invention, there is provided a door device for a dishwasher provided on a front surface of a main body, the door being an inner door, and a decorative panel and a parallel link which are stacked on the front surface. The inner door closes the cleaning tank opening of the main body, and the inner door is attached so as to be openable and closable in the vertical direction, the upper end of the decorative panel is lower than the inner door, and the lower end is the cleaning tank opening. It is formed in a length that covers the front panel of the main body lower than the part, and the parallel link mechanism is configured by attaching the upper and lower ends of the parallel link interposed between the facing surfaces of the inner door and the decorative panel to the opposite surfaces. However, the engaging means that can be engaged and disengaged is provided between the inner door and the decorative panel.

In the door device for the dishwasher having the above structure, the decorative panel covers the front panel of the main body beyond the lower end of the inner door when the door is closed. When opening the door, put one hand on the handle provided at the upper end of the inner door, remove the engaging means by an appropriate method, and open it toward you to keep the inner door and the decorative panel parallel by the parallel link. While rotating, it is rotated downward and released. The lower end of the decorative panel rotates while sliding on the front panel of the main body.

Next, in the invention described in claim 2, a spring for biasing the parallel link in the invention described in claim 1 in a direction of expanding and expanding is attached, and a magnet is used as the engaging means. The attraction force of the magnet is set to be larger than the biasing force of the spring.

In this case, when the door is closed, the attractive force of the magnet overcomes the force of the spring to hold the decorative panel on the inner door.
When the inner door is opened by a force that overcomes the attraction force of the magnet, the parallel link is expanded by the force of the spring, so that the user can open the door with a small force.
