Embodiment Construction

[0027] figure 1A part of a washing container 1 of a dishwasher according to the invention with a spray device according to a first embodiment is shown. A part of the floor of the washing container 1 is shown in sectional view, in which a groove-shaped recess 3 is arranged. Arranged on the recess 3 in the base 2 of the washing container 1 is a removable cover 7 which covers the recess 3 over its entire length. The recess 3 thus cooperates with the cover plate 7 to form a spray channel 4 , which is supplied with washing liquid by the circulation pump during operation. An opening 9 is provided in the cover plate 7 for the exit of washing liquid from the spray channel 4 into the interior of the washing container 1 .

[0028] In the first embodiment, the cover plate 7 has a symmetrical, substantially U-shaped cross section, wherein the two free ends of the U-shaped cross section are formed by arms 8 . The cover 7 is made of an elastic material, so that the arms 8 can be bent tow...

Abstract

The aim of the invention is to provide a device for spraying spray products in a dishwasher, enabling the dishes to be impinged upon with dishwashing fluid in an efficient manner and to avoid wear andtear caused by moving parts and to provide trouble-free operation. According to the invention, a spraying device is provided for spraying dishwashing fluid into the inside of the washing container (1), said device comprising at least one spray channel (4,5) which guides at least one dishwashing liquid and which is integrated into the bottom, top and / or wall area of the washing container (1), whereby openings (9) which are oriented to wards the interior of the washing container are provided on one side, enabling the dishwashing fluid to pass therethrough. As a result the distribution of dishwashing fluid is spread in a more homogenous manner and is improved and it is possible to dispense with moving parts, such as spray arms, for the distribution of said dishwashing fluid, leading to greater freedom in terms of washing container and wash basket design.

Description

technical field [0001] The invention relates to a dishwasher having one or more washing containers and a device for spraying washing items arranged in the washing containers. Background technique [0002] Dishwashers are known which have a spray device which works via a rotating wash arm. Since the washing container in conventional dishwashers generally has a rectangular floor plan and the rotating washing arm has a circular working area, corner areas cannot be sprayed with washing liquid by the rotating washing arm. In addition, the rotating washing arm has the disadvantage that it is a moving part which not only wears out during the movement but also causes great disturbances, for example if the washing items in the range of movement of the washing arm prevent the washing arm from rotating. [0003] Dishwashers with a spray device are also known in the prior art, in which the washing items located in the washing container are acted upon by the washing liquid via fixed noz...
