Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for a dishwasher, particularly an inner tank, and relates to a structure in which parts are sequentially assembled from the inside to the outside around the inner tank.

The structure of the main body of a conventional dishwasher is such that an inner tank is mounted inside the outer case, and a frame is fixed to the lower surface. Therefore, in addition to making the exterior strong in terms of strength, each part must be installed by inserting it inside through a limited opening, and the exterior gets in the way, requiring a lot of man-hours and effort for assembly. It cost a lot of money. Furthermore, during inspection, maintenance, etc., there was a problem in that it was difficult to inspect the internal parts, and parts could not be replaced without removing more parts than necessary.

In addition, for items that are assembled around the inner tank,
Since each part is attached to the inner tank, not only does the structure of the inner tank become complicated, but there are also many mounting holes that pass through the inner tank wall during installation, and water will scatter inside the inner tank, making it difficult to prevent water leakage. The process was not only difficult but also costly.

The present invention solves the above-mentioned conventional problems, and its purpose is to reduce assembly man-hours by simplifying the support structure of the inner tank, and to reduce the number of assembly steps for the inner tank, underframe, exterior, top plate, etc. Even if the strength of individual parts is insufficient, the overall strength can be increased through a comprehensive combination structure.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the figure, 1 is the inner tank of the dishwasher.
Inside, the dishes to be washed are stored in a basket. A cleaning liquid is usually discharged from a spray nozzle into the inner tank 1, and the dishes are washed. Note that the inside of the inner tank is not shown because it is well known in the art. Reference numeral 2 denotes an underframe molded of resin or the like, which is located below the inner tank 1 and forms the base of the lower part of the main body of the dishwasher, and an inner tank support part 3 that projects upward is integrally formed at the rear of the frame. , supports the bottom part 4 of the inner tank 1 and its peripheral part 5.

Reference numerals 6 and 6 denote two pillars that are fixed to the left and right flanges of the front opening of the inner tank 1 from the outside, and their lower ends are placed on the mounting bosses 7 at the front left and right corners of the underframe 2.
It is fastened to the support mounting seat 8 of the pillars 6, 6 from below with a pin screw.

Reference numerals 9 and 9 denote holding fittings that are attached to two places on the left and right sides of the upper peripheral edge of the inner tank 1. These holding fittings 9 and 9 are formed of sheet metal or the like, and claws 10 are formed on the sides of the holding fittings. 10 is engaged with the peripheral edge 11 of the upper surface of the inner tank 1.
Reference numerals 12 and 12 denote an exterior that covers the outer surface of the main body, and has flange portions 13 and 14 at the upper and lower ends. The flange portion 14 on the lower end side is engaged with the lower surface 15 on both left and right sides of the underframe 2, and a plurality of projections 16 are provided on the lower surface 15, and the projections 16 are connected to the exterior 1.
2, 12 is inserted into and locked into an engagement hole 17 formed in the flange portion 14 on the lower end side. This exterior 12,
The front flange 18 of 12 engages with the vertical rib 19 of the column 6 and is screwed to the column 6.

The inner tank support part 3 of the underframe 2 includes a groove part 20 into which the peripheral edge part 5 of the bottom part 4 of the inner tank 1 is fitted, a rib 21 that supports the bottom part 4 of the inner tank 1 from below, and a peripheral part 5 that is held from the outer periphery. It consists of retaining ribs 22 that hold the inner tank 1
A portion of the rear side portion 5A and the side portion 5B of the peripheral edge portion 5 are each held by the support portion 3.

Reference numeral 23 designates a piping relief section formed by recessing the rear part of the underframe 2, through which a drainage hose 24 for discharging the cleaning liquid used inside the main body to the outside of the machine, a pressure hose 25 for water supply, etc. are connected to the outside of the machine. An insertion hole 26 for piping is provided in the back surface 27 of the underframe 2. Even if these hoses 24 and 25 are bent to the left or right after coming out of the insertion hole 26 and installed with the back of the main body pressed against the wall of the room, they will still pass through the space of the piping relief part 23 and connect to the specified connection part. Can be connected.

A reinforcing beam 28 is fixed to the front upper edge of the inner tank 1 and connects and fixes the upper ends of the pillars 6, 6. Reference numeral 29 denotes a back plate that covers the back of the main body and forms a part of the exterior. are screwed onto the rear flanges 31 of the front sheaths 12, 12 in an overlapping manner. Reference numeral 32 denotes a top plate that covers the upper part of the inner tank 1, which covers the upper surface of the reinforcing beam 28 and the outer shell 1.
The upper surface of the flange portion 13 on the upper end side of 2, 12, the back plate 2
9, and are fixed to the reinforcing beam 28 at the front and to the back plate 29 at the rear.

According to the above structure, the inner tank 1 is supported from above and below with the inner tank 1 at the center, and the entire main body is constructed using the inner tank 1 as a sandwich from the left and right sides, and assembly and configuration are extremely simple. It has become a thing. That is, with the underframe 2 as a base, the inner tank support part 3 is provided at the rear of the underframe 1, and since the inner tank support part 3 has the groove part 20, the peripheral edge 5 of the bottom surface of the inner tank 1 can easily move into the groove part 20. Can be inserted into.

In addition, a support column 6 fixed to the front part of the inner tank 1,
The lower end of the inner tank 1 can be fixed to the underframe 2 by simply tightening two screws.
The installation can be completed by simply attaching this to the holder. In addition, the underframe 2 and the holding fittings 9, 9 are attached to the inner tank 1.
However, since they are not fixed in any way in the direction of pulling apart, the exteriors 12, 12 are disposed from both sides, and the flanges 13, 14 provided at the upper and lower ends of this exterior 12, Inner tank 1, underframe 2,
It is possible to clamp parts such as the holding fittings 9, 9 so that they do not come apart. At this time, the flange portion 1 of the exterior 12, 12
3 and the holding fittings 9, 9 are screwed only at one place.

In such a configuration, it is necessary to assemble each part in an orderly manner, but the number of screwed parts is extremely small, and an overall strong structure can be formed without reducing the overall strength.

In addition, the cleaning pump, drainage pump, and other electrical components such as condensers are first assembled on the underframe 1, then the inner tank 1 is placed on top of it, and assembly proceeds from the inside.Finally, the exterior and top plate are placed on top. There are advantages in that a rational method can be used to complete the assembly by just one step, and that only a minimum number of parts 9 need to be attached and detached during servicing, thereby shortening the servicing time.

As described above, according to the main body structure of the dishwasher of the present invention, the number of screwed parts is greatly reduced, and the overall strength can be increased without increasing the strength of each member. This can be done in an extremely rational manner, and has the effect of greatly improving serviceability.
