DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dishwasher having a pivotable door for opening and closing a washing chamber, and more particularly to a mounting structure of door stoppers provided on both sides of the door.

[0002]

2. Description of the Related Art Japanese Utility Model Publication No. 62-590 shown as prior art.
The publication discloses a dishwasher having a hood-shaped door that opens and closes a washing chamber, and opens and rotates the door from bottom to top,
On the contrary, when closing, the rotating operation is performed downward.

Here, when the door is turned to close the door, it is necessary to restrict the rotation so that the door stops at a position where the cleaning chamber is securely closed. In the case of the above publication, in order to make the rack mounting rail detachable from the main body, a stopper made of rubber packing is attached to a support leg which is an attachment member provided on the rack mounting rail, and the door is closed. The lower end contacts the stopper on the main body side so that further rotation is restricted, and the proper closing position can be maintained.

[0004] In the case where the stopper is used to regulate the rotation of the door, the stopper can be provided not on the main body but on the door to perform the same operation.

FIGS. 2 to 4 show a dishwasher of the type in which such a stopper is provided on the door side. Dishwasher 1
A main body 2 covered with a stainless steel panel and containing a cleaning tank, a cleaning pump, and the like (not shown);
A frame 3 having a front opening, which is fixed above the main body 2 and forms a housing, has a handle 4 and a window 5 on the front, and is rotatably attached to the frame 3 by a rotating shaft 6 to be opened and closed. Hood-shaped door 7.

The door 7 defines a washing chamber 8 together with the frame 3, and when the handle 7 is rotated upward by the handle 4, the door 7 is housed in the frame 3 to open the washing chamber 8. When the hood 7 is rotated downward, the notch 9 formed on the left and right sides of the door 7 and the side plate 11 formed above and facing the main body 2 coincide with each other to close the washing chamber 8.

When the door 7 is closed, as shown in FIG. 2, at the lower position of the right and left side surfaces 7b, 7b of the door 7, the upper end 11b of the side plate 11 is contacted, and the closing direction is further increased. Stoppers 12, 12 for restricting the rotation of the shaft are provided so as to protrude outward. When the door 7 is turned and opened, the stoppers 12 and 12 come into contact with the opening edge 3b of the frame 3 as shown in FIG. 4 to restrict further opening and turning. Has become.

A washing rack accommodating dishes and the like to be washed is placed in the washing chamber 6 so as to be freely taken in and out, and washing nozzles are generally arranged above and below the washing chamber 6. .

[0009]

In the dishwasher having the above structure, there is no problem as long as the centers of the left and right stoppers 12 provided on the hood 7 which opens and closes about the rotating shaft 6 are the same. In many cases, the center (stopper center line P shown in FIG. 1) does not match due to variations in production (processing and assembly), and when the hood 7 is closed, the stoppers 12 and 12 come into contact with the side plates 11 and 11 when the hood 7 is closed. And the durability of the hood 7 is degraded, and the opening / closing operation is not performed properly.

The conventional apparatus has not been able to easily adjust for such a center shift of the stopper.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been modified so that the displacement of the left and right stoppers due to production variations can be easily adjusted, thereby preventing contact of the stoppers. It is an object to provide a door stopper for a dishwasher.

[0012]

According to the present invention, a cleaning nozzle is provided near an upper surface opening of a main body, a frame is provided above the main body, and is rotatably supported by the frame and is rotatably housed in the frame. A dish-washing machine having a hood-shaped door defining a washing chamber and having stoppers on both sides of the door for restricting opening and closing of the door. A door stopper for a dishwasher, comprising: a polygonal shaft for attachment; and a stopper member formed with a shaft hole to be fitted to the shaft that is offset from the center and detachably attached to the shaft. And

[0013]

The stopper is formed by fitting a stopper member formed at a position where the shaft hole is shifted to a polygonal shaft protruding from both sides of the door.

Therefore, when the assembled left and right stoppers do not have the same center, the center of the left and right stoppers can be easily matched by performing mounting adjustment such that the stopper member is mounted on the shaft by appropriately changing the set angle. In addition, a stable door opening / closing operation can be performed without generating any contact with the stopper.

[0015]

An embodiment of the present invention will be described below with reference to FIG.

The shaft 15 provided on the left and right side surfaces 7b, 7b of the door 7 for mounting the stopper has a regular hexagonal shape. Reference numeral 16 denotes a circular stopper member which is attached and fixed to the shaft 15. The stopper member 16 is formed of a member having a buffer effect such as rubber. It is formed shifted in position.

As described above, the stopper 12A of the present invention
The stopper member 16 is formed by fitting a shaft hole 17 formed by shifting the stopper member 16 from the center thereof into a mounting shaft 15 having a regular hexagonal shape.

Therefore, by changing the position angle of the mounting of the stopper member 16 with respect to the shaft 15, the position height of the stopper member 16 with respect to the shaft center line changes as shown in FIG. And the stop point can be adjusted.

Thus, the left and right stoppers 12A, 1
2A is provided on both sides of the door 7 at the same height position, and there is no contact when the door 7 is closed.

In the embodiment, the shaft 15 has been described as having a regular hexagonal shape. However, an appropriate polygonal shape such as a regular octagonal shape is also applicable.

[0021]

As described above, according to the present invention, a stopper for a door that opens and closes a cleaning chamber by rotating vertically is provided on both sides of the door. By adopting a structure in which a stopper formed with the shaft hole shifted from the center is mounted on this shaft, the displacement of the left and right stoppers due to production variation can be easily adjusted by changing the set angle of the stopper. . As a result, the door can be assembled with the same stopper on the left and right centers, the stopper is prevented from hitting, the durability of the door is improved, and the door can be opened and closed smoothly. .
