2. Description of the Related Art Dishwashers for automatically washing dishes such as dishes, teacups, and cups after eating and drinking have been installed in kitchens such as coffee shops and restaurants, and even in general households.
It has come to be widely and preferably used. This dishwasher is basically composed of a washing tank that opens upward and a casing-like lid that covers the washing tank from above and defines a washing chamber inside. In addition, a rotatable washing nozzle is provided inside and outside the washing tank, and the nozzle is rotated by the reaction force of the hot water spray to spray hot water to the dishes in the dish rack stored in the washing tank for efficient washing. Is designed to do.

A door handle rotatably supported on a rear frame disposed on the back surface of the cleaning tank is connected to the casing-like lid, and the casing-like lid is rotated by rotating the handle up and down. The body moves up and down to open and close the washing tank. The door handle is formed by bending a cylindrical pipe into a U-shape in a plane, and with both open ends of the handle pivotally supported by the rear frame, the front surface and both side surfaces of the casing-like lid body. It is arranged so as to surround. Further, the side rod of the door handle facing both side surfaces of the casing-like lid is pivotally supported at the other end of a link rod whose one end is pivotally supported at the side surface of the lid, and the casing-like lid is pivotally operated by the door handle. The body is configured to move up and down in parallel.

[0004]

Since the link rod is connected to the outside or inside in the width direction with respect to the door handle and the handle is cylindrical, a large space is provided on both sides of the casing-like lid. It was needed. That is, when a dishwasher is installed adjacent to other equipment in a kitchen or the like, it is necessary to secure a space on both sides of the dishwasher that does not interfere with the door handle, which makes it difficult to effectively use the space in the kitchen. Is pointed out. Therefore, if the door handle is formed of a pipe having a small diameter, the space on both sides of the casing-like lid can be reduced. However, in this case, the operating rod of the door handle facing the front surface of the casing-like lid also has a small diameter, and the operating feeling of the operator is reduced. Further, the strength of the pipe is reduced by making the diameter of the pipe small, and it is difficult to achieve both the strength required for the door handle and the operability and space saving.
