Description

dish washing machine

technical field

The utility model relates to a tableware washing machine, which has a detergent supply hopper arranged in the side wall or door of the washing container, and is installed in the washing container at a height approximately at the height of the detergent supply hopper for accommodating washing items. and at least one washing device above and/or below the washing basket.

Background technique

A detergent supply hopper for a dishwasher is usually arranged in the door of the dishwasher because it is easily accessible for the user. In the supply hopper, the detergent can be placed in fluid form as a powder or as tablets in compressed form. The detergent supply hopper is usually opened in the "wash" step after the pre-rinse process so that the detergent reaches the interior of the wash container. Here, it is desirable that detergent is completely supplied to the washing process and that the supply hopper is completely drained of detergent. This is relatively unproblematic in the case of liquid detergents or detergents in the form of tablets. However, when using powdered detergents, it can happen that after opening the detergent supply hopper, in particular in the case of wet filled detergent, residual detergent remains in the supply hopper.

In DE 85 16 941 U1 a dishwashing machine with a washing container and a washing system for washing liquid arranged therein is known. Furthermore, a cleaning agent outflow opening is provided on the vertical wall of the washing container or in the door, wherein the outflow opening facing the washing container is associated with a washing liquid guide. The guiding device comprises a plurality of webs arranged in parallel at a distance from one another and longitudinally vertical or inclined at an acute angle with respect to a horizontal plane. It should therefore be achieved that the jet emitted by the injection system, in particular by the nozzle of a circularly moving spray arm and on which a rotational pulse is applied, penetrates particularly far into the depth of the outflow opening and thoroughly flushes out the Cleaning agent residue.

Utility model content

The object of the present invention is to propose an alternative device which can be used more flexibly than known devices and which offers greater efficiency.

This object is solved by a dishwasher with the features of claim 1 . According to its characteristic feature, a guide device is provided on the cutlery basket, which guides the jet of washing liquid from the spray device, for example a spray arm, to the detergent supply hopper. Only by providing the guide device on the cutlery basket is it possible to arrange the guide device over a large area, so that it thus forms the beam over a larger area. The efficiency can thus be significantly increased compared to the prior art. Furthermore, with the guiding device of the present invention, different kinds of detergent hoppers or detergent supply devices can be used, resulting in increased flexibility. On their upper and lower sides, the guiding device each has a reflective surface which deflects the impinging jet in the direction of the detergent supply hopper. The guide device preferably extends along a plane of movement or action corresponding to the spray device on the crockery basket. For spray arms that pivot in a horizontal plane above or below the cutlery basket, the guide device therefore likewise extends substantially in the horizontal direction on the cutlery basket. Likewise, the guide device is also arranged to cooperate with a top spray head, which sprays water from the top of the washing container and acts on the horizontal cutlery basket with a jet from above.

Depending on the exact position of the cutlery basket relative to the detergent supply hopper, the guide must change its inclination in order to guide the water jet into the detergent supply hopper. To this end, an advantageous embodiment of the invention provides that the guide means are arranged adjustably. As a result, the corresponding geometrical positional relationship of the guide device can be adjusted so that its reflective surface achieves a desired inclination. It is therefore not necessary to modify the guiding device itself or the crockery basket, but its function is optimized, for example, for all types of dishwashers.

According to a further advantageous embodiment of the invention, the guide device can be provided in a detachable manner. The guide device can therefore be equipped with a clamping or clamping device, with which the clamping device is fastened to the crossbeam or web of the cutlery basket. This makes it easier to replace the guide device, for example in the event of damage, and enables retrofitting.

According to another preferred embodiment of the invention, the guiding devices can be connected to each other. For example, the guide device can be arranged in the frame or on a web extending vertically in the installed state, on which the fastening device is arranged. Together they thus form an assembly which can be mounted more easily and, if necessary, replaced as a guide assembly.

According to an alternative embodiment of the invention, the guide device can be formed separately, ie not coupled to one another. Being a single module has the advantage that, in particular in the case of damage, it can be replaced individually, thus making repairs more cost-effective.

According to a further preferred embodiment of the invention, the guide device can only be arranged in the region of the detergent supply hopper. This is a cost-effective embodiment since it uses the least amount of material for the guide.

According to a further preferred embodiment of the invention, the guide device can be arranged around the cutlery basket, at least on the entire side of the cutlery basket facing the detergent supply hopper. In this embodiment, the guide device not only takes over the role of guiding the water jet to the detergent supply hopper, it also serves as acoustic protection over the remaining area, since the water jet impinging on the guide device is splashed and thus No crackling on the metal inner wall of the washing container, especially the door. In this way, the guiding device can achieve a double effect, namely, on the one hand, the detergent supply hopper is completely flushed out, and on the other hand, the running noise of the dishwasher is reduced.

The guide or its reflective surface must be aligned with the direction of entry of the water jets, depending on the relative positions of the detergent supply hopper, the crockery basket and the spray arm. The guide device can be acted upon not only by the water jets from the spraying device arranged above the cutlery basket but also by the water jets from the spraying device arranged below the cutlery basket. In the case of simple guides with a rectangular cross-section and reflective surfaces parallel to one another, the inclination of the reflective surfaces adjusted for the water jet striking from above is not suitable for the water jet striking below. A further preferred embodiment of the invention therefore provides that the cross-section or the longitudinal section of the guide device has a transverse contour which is not rectangular. For example, a triangular or wedge-shaped or truncated-conical transverse profile can be selected, one of its sharp corners pointing towards the detergent supply hopper. Reflecting surfaces which are at an angle to each other are thereby formed. Thus, the water jets striking the guide device both from above and from below strike at as flat an angle as possible, so that they can be deflected almost without scattering losses. Additionally or alternatively, the upper side and/or the lower side of the guide device can be concavely arched. Through this modified guide, it is possible that the water jets hitting the reflective surface are not scattered, but are completely diverted into the detergent supply hopper. Furthermore, the cross-section of the guide device can, for example, be sector-shaped or curved segments with different radii of curvature.

The guide device preferably has, for example, a circular or rectangular channel through which the washing liquid can flow. Thus, for example in the case of relatively large guides, the washing liquid can also hit the washing items, which otherwise would not be acted upon by the washing liquid.

In another embodiment, the guiding means are movable by a mechanism such that when one guiding means is adjusted, at least the other guiding means is adjustable. The operating comfort for the user is thus increased since, for example, only one guide device has to be adjusted. The mechanism, for example a toothed wheel with a corresponding transmission ratio, is preferably formed such that when adjusting the individual guides, an optimization of the effect of all guides can always be achieved.

According to another preferred embodiment of the invention, the guide device can be cast on the cutlery basket or formed in one piece with the cutlery basket. The guide device can thus be produced together with the cutlery basket in one operation. Therefore, on the one hand, a stable combination of the guide device and the cutlery basket can be achieved, and on the other hand, the installation effort can be reduced.

Furthermore, the object of the invention is solved by a guide device according to one of the claims for being installed in a dishwasher and mounted on a crockery basket arranged approximately at the level of the detergent supply hopper.

According to the invention, the cutlery basket can also be provided with a guide device as described above.

A door 4 in which a detergent supply hopper 5 is arranged can be used to open the washing container 2 for insertion of the crockery basket 3 . The detergent supply hopper 5 is located approximately at the level of the upper crockery basket 3 . The detergent supply hopper is used to contain dishwashing agent before the operation of the dish washing machine 1, and to release the detergent in time during the washing process. This is done in such a way that a closed flap (not shown) or a movable cover (not shown) of the detergent supply hopper 5 is opened programmatically. The dishwashing agent in the detergent supply hopper 5 is then fed into the wash cycle by gravity through an inclined wall 6 of the detergent supply hopper 5 .

The spray arm 7 is located below the cutlery basket 3 . They are provided over their entire length with nozzles, not shown, through which the spray arms inject the washing liquid in the water jets 8 into the crockery basket 3 from below. In addition, a top spray head 10 is arranged below the top 9 of the washing container 2 , which fills at least the upper crockery basket 3 with washing liquid from above and emits a water jet 11 .

On the front side of the upper cutlery basket 3 facing the door 4 , in the region of the detergent supply hopper 5 , a stop 12 is arranged as a guide. The baffle is swingably connected with the cutlery basket 3 . The baffle or guide 12 is sprayed from below by the water jet 8 from the outer nozzle of the upper spray arm 7 and by the outer jet 11 of the top spray head 10 . The water jet 11 from the top spray head 10 strikes the upper reflective surface 13 of the baffle or guide 12 , and the water jet 8 from the spray arm 7 strikes the lower reflective surface 14 . The deflector or guide 12 is adjusted such that the jets 8 , 11 are deflected from their original direction when they hit the reflective surfaces 13 , 14 and are guided into the detergent supply hopper 5 . If the detergent supply hopper 5 is opened, it is acted upon by the deflected jets 8 , 11 , so that the dishwashing agent therein is completely flushed out for sufficient supply for the washing process. The guide means 12 is preferably formed plate-shaped, with a rectangular cross-section or longitudinal section, but can also have any other shape, for example arched, blade-like surfaces, or wedge-shaped or truncated-conical in cross-section or longitudinal section. In the side view from above according to FIG. 2 , the guide device can have any shape, for example rectangular, circular or oval.

It is indicated here that the dishwasher described in detail above is an embodiment which can be modified in different ways by a person skilled in the art without departing from the field of the invention. In particular, the specific configuration of the baffle can also be realized in other forms than described here. For the sake of completeness, it is further pointed out that the use of the indefinite article "a" does not exclude that the associated characteristic can also have a plurality.
