Description

[Detailed description of the invention] This invention prevents the splashing of the cleaning liquid sprayed from the rotating nozzle, the steam leakage and cleaning noise leakage during hot water cleaning and hot water rinsing, and also prevents floating debris that adheres to each groove and rib. To provide a dishwasher that can effectively wash away all kinds of dirt.

Conventionally, gaskets for dishwashers have a complicated cross section, usually consisting of a mounting flange part and a gasket part.
This flange portion is fixed to the tank between mounting plates.

Although the gasket part is connected to one end of the flange part, only one side of the gasket part is stuck and the shape becomes unstable in many cases.

This gasket was attached to a stepped portion around the opening of the cleaning tank, but the cleaning liquid came into direct contact with the gasket, causing severe aging deformation of the gasket.

Furthermore, since the gasket part is hit by a strong jet of liquid, there is a risk of liquid leaking from the sealing part, leading to deterioration of the sealing performance of the opening and water leakage accidents.

The present invention was devised to solve these problems, and its configuration will be described below.

In the figure, reference numeral 1 denotes the main body of the dishwasher, which has a washing tank 3 inside and a lid 2 disposed to cover the front opening of the washing tank 3.

A lid back plate 4 is attached to the inner surface of the lid 2.

A groove 5 is provided on the periphery of the front opening of the cleaning tank 3.
Correspondingly, ribs 6 are formed to protrude from the lid back plate 4.

A gasket 7 having a rectangular cross section and a mouth-like overall shape is fitted into the groove 5, and the tip of the rib 6 is in contact with the gasket 7.

There is another row of grooves 8 on the inner peripheral edge of the groove 5 of the cleaning tank 3, and ribs 9 are arranged on the lid back plate 4 in correspondence with this.

A notch 11 is provided in a central part above the side wall 10 of this groove 8.
has been established.

The cleaning liquid jetted from the jetting rotary nozzle 12 provided at the center of the bottom of the cleaning tank 3 is particularly introduced through the notch 11 of the groove 8 described above, flows horizontally along the side wall 10, and flows horizontally along the side wall 10.
Side walls 13 and 14 descending on both sides of the opening continuous with
It returns to the lower part of the cleaning tank 3 along the way.

Further, the cleaning liquid flowing into the upper surface of the rib 9 provided on the lid back plate 4 also flows along the side wall 10 of the groove 8 of the cleaning tank 3, and similarly to the cleaning liquid, it flows along the outer periphery along the rib 9 on the outer periphery of the lid back plate 4. Return to the bottom of cleaning tank 3.

In the above configuration, the gasket 7 is provided in the groove 5 of the cleaning tank 3, so that even if the cleaning liquid is sprayed from the jet rotation nozzle 12, the side wall 10. Interrupted by ribs 9 and grooves 8,
It almost never reaches gasket 1.

In particular, what reaches this gasket 7 is fine scattered water or water vapor generated from the cleaning liquid, and the noise of the jetted cleaning water.

Therefore, there is no problem even if the sealing at the 7th part of the gasket is not sufficient, and since it is not exposed to cleaning liquid, there is little concern about aging.

By the way, the problem with such a structure in which the injection liquid is blocked by a narrow gap is food debris that remains in the gap, and once it has entered, it is difficult to get out.

However, the cleaning liquid is introduced through the notch 11 provided in the side wall 10 of the groove 8, and the water flows from the center of the upper side to the left and right.

Therefore, water flows through each rib and side wall, washes away debris, and is led to the lower part of the cleaning tank 3.

Therefore, the ribs and grooves will be cleanly cleaned after the final cycle.

In the above embodiment, the ribs 6.9 were provided on the lid 2 side and the grooves 5, 8 were provided on the cleaning tank 3 side, but the same effect can be expected even if the positions of the ribs and grooves are reversed. , it is not necessarily necessary to provide a plurality of ribs and grooves, and for example, it is possible to have only a groove 8 provided with a gasket 7.

As is clear from the above embodiments, the dishwasher of the present invention achieves airtightness through a combination of grooves, ribs, and gaskets, and prevents splashing of cleaning liquid, leakage of water, steam leakage during hot water washing and rinsing, and cleaning. Not only can noise leakage be prevented, but also floating debris can be effectively washed away.

Furthermore, since the groove is provided with a notch to introduce the sprayed liquid into the groove, debris in the groove can be washed away very effectively with simple means, and the groove can be cleaned thoroughly.
