Description

[Detailed description of the invention] This invention prevents the splashing of the cleaning liquid sprayed from the rotating nozzle, prevents the leakage of steam and noise during hot water cleaning and rinsing, and effectively washes away floating debris. The present invention provides a dishwasher with the following features.

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 step around the opening of the cleaning tank, but the cleaning liquid came into direct contact with the gasket, resulting in 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 has been 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 that can be opened and closed to cover the front opening of the washing tank.

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 outer peripheral edge of the grooves 5 of the cleaning tank 3, and ribs 9 are arranged on the lid back plate 4 in correspondence with this.

12 is a rotating jet nozzle installed at the center of the bottom of the cleaning tank 3;
A part of the cleaning liquid sprayed from here is particularly
The water flows horizontally along the side wall 10 constituting the groove, and returns to the lower part of the cleaning tank 3 along the side walls 13 and 14 that descend to the periphery on both sides of the front opening that is continuous with the side wall 10.

Further, the cleaning liquid injected onto the upper surface of the rib 6 provided on the lid back plate 4 also flows along the outer circumference along the rib 6 of the lid back plate 4 in the same manner as the cleaning liquid that flows through the side wall 10 of the groove 5 of the cleaning tank 3. Return to the bottom of the page.

As shown in FIG. 4, both lower ends of the gasket 7 correspond to the lid opening/closing locus (radius R) of the lower ends of the ribs 6 provided on the lid 2.
It is located outside and is disposed above the lid opening/closing fulcrum 11 (H above the lower end of the groove 5).

15 is a groove formed at the lower end of the cleaning tank 3; 16 is the groove 15;
The lower end of the lid back plate 4 comes into contact with the backing when the lid 2 is closed.

The above-mentioned dishwasher is used in the same way as a normal dishwasher, but when the lid 2 is closed, the tips of the ribs 6 abut against the gasket 7 to maintain airtightness.

Note that since the groove 5 communicates with the inside of the cleaning tank 3, debris adhering thereto can be washed away by the liquid flowing along the groove 5 and returned to the cleaning tank 3.

As is clear from the above-mentioned embodiments, the dishwasher of the present invention maintains 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, Not only can leakage of cleaning noise be prevented, but also floating debris can be effectively washed away.

Also, since the gasket is installed in the groove, configuration 2
There are no problems with conventional methods in terms of operation and function.

In addition, since the relationship between the opening and closing of the lid and the gasket is taken into consideration, the gasket will not be damaged or misaligned due to opening and closing of the lid (and will exhibit stable performance over a long period of time).

Claims (1)

[Scope of utility model registration request] A groove is formed on the periphery of the front opening of the cleaning tank having a rotating injection nozzle, a rib corresponding to the groove is formed on the periphery of the lid that closes the opening of the cleaning tank, and these grooves and ribs are fitted. At the same time, the groove is equipped with a gasket that comes into contact with the tip of the rib, and the lower ends of this gasket are located outside the lid opening/closing locus of the lower end of the rib provided on the lid, and above the lid opening/closing support point. Dishwasher installed.
