Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to preventing water jets generated during washing from leaking to the outside in a dishwasher having a jet nozzle.

Conventionally, to prevent water leakage in this type of dishwasher, as shown in Fig. 3, a gasket 21 is attached to the upper opening edge of the washing tank 20 or the opening edge of the lid 7 to prevent water from leaking to the outside. Was.

However, according to this configuration, the gasket 2 for preventing water leakage
1, which is troublesome to install and requires extra parts, resulting in high costs.

The present invention was devised in view of these drawbacks, and aims to prevent water from leaking to the outside with a simple structure and low cost.

The structure of the present invention consists of a washing machine main body that has an injection nozzle inside and has an open top surface, and a dome-shaped lid body that covers the top surface opening so that the top surface can be opened and closed. a flange wall oriented toward the direction of the flange, and a vertical wall extending substantially perpendicular to the flange wall; on the other hand, an inwardly inclined surface is formed on the outer periphery of the opening edge of the lid; When closing the opening of the main body, the opening edge of the lid body is placed on the flange wall soil, the outer peripheral surface is in contact with the inner surface of the vertical wall, and the inclined surface, the flange wall, and the vertical wall are connected to each other. A space is formed.

The above-mentioned structure prevents the water jetted from the jet nozzle generated during cleaning from leaking to the outside from between the lid and the main body of the washer.

Embodiments of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a washing machine main body with an open top surface, which includes a rotatable injection nozzle 2, a circulation pump 3 that circulates washing water to the injection nozzle 2 and causes it to rotate, and a filter 4 that removes leftover food.
and a drain hose 6 with a drain valve 5 interposed therebetween.

Reference numeral 7 denotes a dome-shaped lid body that closes the upper opening of the washing machine main body 1 in a freely openable and closable manner.

A flange wall 10 oriented outward is integrally formed on the upper opening edge of the washing machine main body 1, and a vertical wall 11 is integrally formed at the tip of the flange wall 10 in a substantially vertical direction.

The flange wall 10 is sloped low toward the inside of the washing machine main body 1, as shown in FIG.

A thick part 13 is integrally formed on the outer periphery of the opening edge of the lid 7, and an inwardly inclined surface 13a is formed on the outer periphery of the thick part 13.
is formed.

Therefore, according to such a configuration, when the opening tip 7a of the lid 7 is placed on the inclined surface 13a in order to close the upper opening of the washing machine main body 1 with the lid 7, the outer peripheral portion of the thick portion 13 13
b is in contact with the vertical wall 11, and the inclined surface 13a, the flange wall 10, and the vertical wall 11 form a space A, and the water jetted from the jet nozzle 2 is directed toward the inner wall of the upper opening edge of the washing machine main body 1 as shown by the arrow B. Or, if it hits the inner wall of the lower opening edge of the lid 7, it hardly leaks to the outside from the gap C formed between the flange wall 10 and the opening tip 7a of the lid 7, and even if it leaks, it will leak inside the space A. It circulates like E and does not leak to the outside.

Therefore, since the present invention is constructed as described above, it has a simple structure and reliably prevents the leakage of jet water to the outside without requiring extra parts such as gaskets for preventing water leakage as in the past. It is something that can be prevented.
