Description

[Detailed Description of the Invention] (a) Field of the Invention The present invention relates to a dishwasher equipped with a washing chamber partitioned by a frame and a rotatable door on a main body of the dishwasher whose top surface is open, and particularly relates to Regarding the configuration of the door, frame, and main body.

(b) Background technology and its problems A main body in which a rotating cleaning nozzle is disposed in an opening on the top surface and a cleaning tank is formed below the rotating cleaning nozzle;
In the dishwasher, the dishwasher is equipped with a frame that partitions a washing chamber on the main body and a rotatable door. Since the frame is fixed to the main body with screws, fixing the frame to the main body is complicated when manufacturing a dishwasher.Furthermore, when servicing the main body such as cleaning the washing tank, the support member must be removed from the main body and the door removed from the main body. At the same time, the frame must be removed from the main body by removing all the screws, making the removal work of the door and frame extremely complicated, and the work of attaching the door and frame to the main body also extremely complicated due to the screws, etc. .

(c) Purpose of the invention To simplify the work of manufacturing and servicing a dishwasher by simplifying the work of removing and attaching the frame and door that partition the washing chamber to the main body of the dishwasher with an open top surface. The purpose is to make inspection work easier.

(d) Embodiments of the present invention The following will explain based on FIGS. 1 to 6.
1 is a hood type dishwasher, the periphery and bottom of the washing machine body 2 are covered with a stainless steel panel 3, and legs 4 supporting the main body 2 are provided at the four corners of the bottom.
...... is attached, and a switch section 5 for operation control is provided on the front. Furthermore, a cleaning chamber 6 is divided and formed on the washing machine main body 2, and an opening 7 is formed in the rear half of the cleaning chamber 6, which consists of the upper surface and the rear half of the left and right side surfaces, and the left and right side plates 8', 8. ′,
It is covered by a frame 8 consisting of a top plate 8'' and a rear plate 8, and a handle 9A is attached to the front half portion consisting of approximately the front half of the top surface and both left and right sides, and the front surface.
The left and right side plates 9', 9' and the bent plate 9'' are covered by a door or hood 9 integrally formed of, for example, resin, and the hood 9 is located at the lower front end of the left and right side plates 8', 8' of the frame 8. A hinge 10 having an L-shaped cross section fixed by screws B, B, an opening 10' formed in the hinge 10, and left and right side plates 9' of the hood 9,
A screw B' that communicates with the opening 9a' formed at the rear lower part of the screw B' and a cap nut C that fixes the other end of the screw B'.
The hood 9 is rotatably supported by a supporting member E consisting of a washer D that maintains a gap between the opening 10' and the opening 9a', and the opening 7 of the frame 8 can be opened and closed. Furthermore, at the bottom of the frame 8 there is a cleaning tank 2 around the opening of the main body 2.
A mounting part 8a is placed on the upper surface of the upper flange 2a' formed by bending the inner wall 2a of A to the outside, and the upper part is bent downward at a right angle from the inner tip of the mounting part 8a. A lower flange 8b that fits inside the flange 2a' is formed by bending, and a gap is provided between the cleaning tank inner wall 2a and the lower flange 8b. Further, a frame stopper 8c is fixed to approximately the center of the lower part of the rear plate 8 of the frame 8 by, for example, spot welding, and is located outside the upper flange 2a' and prevents the frame 8 from moving forward. Note that the same effect can be obtained even if the frame stopper is provided over substantially the entire width of the rear plate 8, or even if it is fixed at a plurality of locations.

A rail 12 is provided on the top surface of the washing machine main body 2 via a rail mounting plate 11 attached to the frame 8, and a rotatable washing nozzle 13 disposed on the top of the washing machine main body 2 is mounted on the rail 12. A water splash prevention plate 14 is integrally formed, the lower end of which covers the outside of the rotation locus and extends below the cleaning nozzle 13.
At approximately the center of the surface of the water splash prevention plate 14 close to the lower end of the hood 9, the rotation of the hood 9 is stopped when the door is closed;
A first holding member, ie, a stopper 15, which holds the hood 9 in a predetermined position is attached by, for example, screws or spot welding. The stopper 15 is formed in a substantially dogleg shape and is composed of a mounting portion 15A and an abutting portion 15B that is bent at the upper end of the mounting portion 15A and inclined outwardly and upwardly. Further, the lower end of the hood 9 is bent over its entire width toward the splash prevention plate 14, and a cushion 16 made of soft rubber or the like is placed approximately in the center of the bent portion of the hood 9.
When the stopper 15 is closed, the contact portion 15 of the stopper 15
It is attached so that it is in contact with B. Also, at approximately the center of the lower part of the side surface of the cleaning chamber on the rear plate of the frame 9, there is a second groove which, when the hood 9 is rotated into the frame 8, comes into contact with the rear end of the hood 9 and stops the rotation at a predetermined position. A holding member 17 is attached.

Therefore, by lifting the hood 9 and frame 8 as shown in FIG. Since the hood 9 and frame 8 are connected through the main body 2, the hood 9 and frame 8 can be removed from the main body 2 very easily. Lower it to the upper surface, insert the lower flange 8b inside the upper flange 2a' so that the frame stopper 8c is positioned outside the upper flange 2a', and the lower end of the hood 9 is positioned inside the upper flange 2a', and then lower the frame stopper 8c to the inside of the upper flange 2a'. 8a on the upper surface of the upper flange 2a', it is possible to simplify the work of connecting the hood 9 and the frame 8 to the main body during the manufacture of the dishwasher, and to simplify the work during maintenance and inspection. The frame 8 and the hood 9 can be easily attached and detached. Furthermore, during cleaning, the cleaning water, etc. that travels along the inner surface of the frame 8 travels through the upper surface of the mounting portion 8a and the inner surface of the lower flange 8b, and drips into the cleaning tank 2A, thereby preventing the cleaning water, etc. from leaking to the outside surface of the main body 2. Furthermore, the stopper 15 and the second holding member 17 can reliably hold the hood 9 in a predetermined position when opening and closing the door, and when removing the hood 9 and frame 8.

(e) Effects of the present invention As described above, the present invention not only allows the frame and hood to be easily removed from the main body, but also simplifies maintenance and inspection work inside the main body of the washing machine.
By removing the frame and hood from the main body, the rail, splash prevention plate, and holding member can be removed from the main body together with the hood, making cleaning nozzles and filters easy to maintain and inspect. be able to. In addition, the lower flange formed at the lower part of the frame is positioned between the inside of the upper flange of the main body and the water splash prevention plate that surrounds the outside of the rotation locus of the cleaning nozzle, and the lower edge of the hood is A retaining member provided on the outer surface of the splash prevention plate is used to hold the water between the inside of the upper flange of the main body and the water splash prevention plate, so that the cleaning water and water that travels along the inner surfaces of the frame and hood during cleaning are prevented. This provides a practical advantage in that the cleaning water sprayed from the cleaning nozzle can be returned to the cleaning tank, thereby reliably preventing the cleaning water from leaking out of the main body.
