Description

[Detailed Description of the Invention] (a) Industrial field of application The present invention relates to a dishwasher for cleaning by placing a rack containing an object to be cleaned on a frame-shaped rack rail, and in particular, a rack rail It is about improvement.

(B) Prior art As a prior art, in Japanese Utility Model Publication No. 54-27820, a main body having an open upper surface and a door body capable of moving up and down are formed, and the door body is fitted with a gap inside the main body. In a dishwasher that divides and forms a combined washing room, the rail frame is configured so that rails with guide walls or rails without guide walls and four short legs are screwed, and the four rails are detachable. And especially,
A structure is disclosed in which the rack can be taken in and out from all three directions depending on the installation position of the dishwasher main body by replacing the guide rails having the guide walls.

(C) Problems to be Solved by the Invention Since the conventional rack rail receives all the load by the short legs, there is a problem in the strength of the short legs.
Also, since each of the four rails is screwed to the short leg and connected, the rack rail must be removed when replacing the guide rails, and at least two short leg screws must be removed. It was bad.

In addition, the connection by screwing causes looseness of the screw due to vibration during operation of the washing machine, which causes rattling of the rail.
There was also a problem that interfered with the rack loading and unloading.

In view of such problems, the present invention provides a rack rail for a dishwasher, which aims to easily replace guides and improve the strength of the structure.

(D) Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a dishwasher including a rack rail formed by connecting four rails to a frame-shaped rack rail at an upper opening of a main body. First and second rails having leg portions attached to a support fixed to the inner surface of the main body by bending the portion downward, and stepwise pushing at both ends by the thickness of the first and second rails Third having a bending surface
And a fourth rail, an upward bending portion formed by bending the outside of the first rail upward, and a removable rack guide provided on any of the second, third, or fourth rails, It is a rack rail of a dishwasher in which both ends of the first and second rails are welded to step-bending surfaces of the third and fourth rails to form a frame shape.

(E) Action In the present invention, since both end portions of the first and second rails are welded to the stepped bending surfaces of the third and fourth rails to form a frame shape,
The strength against vibration during operation of the washing machine is also improved, and since there is no step at the rail connection portion, the rails are flush with each other, and racks can be taken in and out smoothly. Furthermore, since the rack guide is detachably attached to any of the second, third, or fourth rails, the rack guide can be attached or detached while the rack rail is attached to the main body.

(F) Embodiment An embodiment of the present invention will be described below with reference to the drawings. Second
In the figure, a main body 1 having an open upper surface and a door body 2 which can be moved up and down are formed, and the door body 2 is fitted inside the main body 1 to define a cleaning chamber 3. A cleaning nozzle 4 and a rinsing nozzle 5 are arranged above and below the cleaning chamber 3, and the lower cleaning nozzle 4
And in the main body opening part slightly above the lower rinsing nozzle 5,
A rack rail 8 is provided for mounting a rack 7 that stores the object 6 to be cleaned.

The rack rail 8 to be cut is constituted by connecting four rails 9, 10, 11, 12 in a frame shape as shown in FIGS. 1 and 3 to 5. That is, the first and second rails 9 and 10 are
Both ends in the longitudinal direction are bent downward to form a leg portion 13, and the leg portion 13 is composed of an insertion portion 13C having an inclined portion 13A and a stopper portion 13B. Of these, the first
The rail 9 has an inner side bent downward and an outer side bent upward, and the upward bent portion is used as a rack guide 14.
Further, the second rail 10 is bent downward on the inner and outer sides, and the outer bent portion is used as a mounting surface 26 of the removable rack guide 15.

On the other hand, the third and fourth rails 11 and 12 are formed with step-push bending surfaces 16 corresponding to the thickness of the first and second rails 9 and 10 at both ends in the longitudinal direction, and the inner and outer sides are directed downward. It's bent. Of these, the outer side is bent a plurality of times to form a vertical mounting surface 17 on which the rack guide 15 is mounted, a horizontal surface 18, and an inclined connecting surface 19.

Then, both ends of the first and second rails 9 and 10 are placed on the step-push bending surface 16 of the third and fourth rails 11 and 12, and the two are connected by welding. The inclined portions 13A of the legs 13 of the second rails 9 and 10 are connected to the connecting surfaces 19 of the third and fourth rails by welding. This completes the assembly of the frame-shaped rack rail 8. The upper surfaces of the rails 9, 10, 11, 12 are flush with each other by the action of the step-bending surface 16.

As shown in detail in FIG. 1, the rack rail 8 is provided with a support fitting 20 fixed to the inner surface 1A of the main body 1, a first and a second support rail 20.
The insertion portions 13C of the leg portions 13 formed at both ends of the rails 9 and 10 are inserted, and the attachment is completed with the stopper portion 13B being locked to the upper edge 20A of the support fitting 20.

Fig. 6 shows the usage state when the rack 7 is straight in and out. In this case, the rack guide 15 is used for the second rail
Mount on mounting surface 26 of 10. Further, FIG. 7 shows a state of use when the rack 7 is taken in and out at a right angle, and in this case, the rack guide 15 is attached to the attachment surface 17 of the third rail 11. As a result, one dishwasher can be used for both straight type and corner type.

(G) Effect of the Invention As described above, since the rails are welded to form a frame-shaped rack rail, the present invention has an advantage of improving strength against vibration during operation of the washing machine. In addition, since no step is formed in the rail connection portion, the rails are flush with each other, and the rack can be smoothly taken in and out from any direction, and the rack can be mounted on either the second rail, the third rail, or the fourth rail. Because the guide is attached detachably,
The rack guide can be attached and detached with the rack rail attached to the main body, and the rack type can be used according to the place of use, either a straight type for straight loading or unloading or a corner type for loading or unloading at a right angle, which can significantly improve usability. Play.
