Description

The invention relates to a dishwashing machine, in particular a domestic dishwasher, with a washing compartment providing a washing compartment, which has a loading opening for loading the washing compartment with to be cleaned items, and with a pivotally mounted about a horizontally extending pivot axis Spülraumtür for fluid-tight closing of the feed opening.

Automatic dishwashers in general, as well as household dishwashers in particular, are well known in the art. They have a housing housed in a washing container, which in turn defines a washing compartment. When used as intended, the washing compartment receives items to be cleaned, which in the case of a household dishwasher, for example, are crockery and / or cutlery items. For loading the washing compartment with items to be cleaned, the washing container provides a charging opening. This can be closed in a fluid-tight manner by means of a flushing door, which flushing door is preferably pivotably mounted about a horizontally extending pivot axis.

For a loading of items to be cleaned with rinse liquor is a spray, which usually has a plurality within the Spülbehälters rotatably arranged spray arms.

In order to achieve an optimized rinsing or cleaning result, process chemicals are generally used, which are supplied to the dishwasher rinsing chamber in the course of a rinsing or drying process. Such process chemicals may be, for example, cleaning chemicals which are supplied to the wash cabinet depending on program control.

According to a previously known and evaluated in everyday practice construction serves to accommodate pourable cleaning agent inside a Spülraumtür trained pantry. This is open on one side and has the closure of the open side via a pivotable closure cap. In this case, the closure lid is under spring action under the action of a spring biased and is due to its endeavor to pivot in its open position, that is, in its the volume space of the pantry releasing position.

When the dishwasher door is open, the storage compartment formed inside the door is accessible on the user side. After a manual filling with cleaning agent, the sealing cap must be closed on the user side against the spring force acting on it. As then the Spülraumtür can be closed and a washing program can be started as intended. During the wash program, a locking of the closure lid is released under program control, as a result of which the closure lid moves due to the spring force acting on it in its open position. The detergent stored within the chamber can now enter the washing compartment provided by the washing compartment.

Although the above-described construction has proven itself in everyday practice, there is room for improvement. It is particularly desirable to allow the user a simplified handling. It is therefore an object of the invention to further develop a dishwasher of the type mentioned in that simplified or even increased process reliability simplified handling is possible on the user side.

To solve this problem, a dishwashing machine of the type mentioned above is proposed by the invention, which has a metering device for pourable detergent absorbed by the dishwasher door, wherein the metering device has a Reinigungsmittelauslass, the door inside the Spülraumtür opens into the washing compartment, the Reinigungsmittelauslass equipped with a splash guard is.

The dishwasher according to the invention has a metering device for pourable detergent. This serves to program-controlled to bring detergent into the provided by the washing compartment of the machine dishwasher.

The metering device provides a reservoir for storing detergent. This reservoir receives detergent in an amount more preferred Sufficient for 20 to 30 rinses. Advantageously, it is therefore no longer necessary on the user side to carry out a detergent dosing manually for each rinsing process. The user-side handling of the dishwasher is therefore simplified.

According to the embodiment of the invention, the metering device is received by the Spülraumtür. For this purpose, inside the dishwasher door, i. between inner panel on the one hand and outer panel on the other hand formed a receiving area in which the metering device is arranged. The reservoir of the metering device is exchanged on the user side, i. used interchangeably in a corresponding door-side recording. If necessary, an empty storage container can be exchanged for a supply container filled with detergent on the user side. There are two different configurations conceivable in this context. According to a first alternative, the metering device and / or the reservoir of the metering device are designed to be accessible on the outside of the door. It is thus a user-side operation of the metering device from the outside possible. It is preferred in this context that the metering device has an externally accessible inlet opening for pourable cleaning agent. A filling of the metering device with detergent to be stored can thus be made on the user side in a simple manner from the outside. According to a second and preferred alternative, the metering device and / or the reservoir provided by the metering device are designed to be accessible on the inside of the door. In this case, a user-side replacement of the reservoir and / or a refilling of the reservoir is only possible with the dishwasher door open. An advantage of this embodiment, in contrast to a door outside accessibility, however, that any sealing problems are avoided and it requires no special cover, as it is required for a door outside accessibility to protect the metering device and / or the reservoir.

For a purposeful introduction of detergent from the metering device in the washing compartment provided by the washing compartment of the dishwasher serves a provided by the metering device Reinigungsmittelauslass. This is formed inside the door of the Spülraumtür and opens into the dishwasher dishwasher. In the intended use case thus arrives detergent stored by the metering device via the detergent outlet of the metering device into the machine-side washing compartment.

It is inventively provided that the Reinigungsmittelauslass is equipped with a splash guard.

The splash guard ensures that the penetration of impurities, dirt and / or the like is prevented in the detergent outlet, especially when the dishwasher door is open.

The construction according to the invention makes it possible, in particular, to be able to meter process chemicals into the washing compartment provided by the washing compartment, the advantage of the configuration according to the invention being to be able to store cleaning agents for more than just a washing program, thus achieving a simplified handling of the automatic dishwasher.

During a loading or unloading of the dishwasher, the Spülraumtür is pivoted to its open position, in which it is generally aligned parallel to the horizontal. In this position of the Spülraumtür falling from above dirt particles, such as food scraps and / or the like may fall into the inside of the dishwasher door formed Reinigungsmittelauslass the metering device and cause it to blockage. A proper use of the metering would then no longer possible. In order to avoid such a blockage, a splash guard according to the invention is provided, which covers the cleaning agent outlet in the closed position.

The falling of dirt particles is in everyday practical use not be avoided because an assembly of automatic dishwashing takes place out of the dishwasher dishwasher washing out Spülkörben in the herausverfahrenen state either door inside the Spülraumtür supported on this or carried by rails above the in Opening position located Spülraumtür are positioned. The washing utensils introduced into the rinsing baskets of an automatic dishwasher in the intended manner are therefore unavoidably arranged above a rinsing-room door which is in the open position, so that any of the Dishwashing falling or dripping dirt particles, liquids and / or the like inside the door impinge on the Spülraumtür. Thus, it is not due to an unwanted obstruction of the inside of the door according to the invention the Spülraumtür trained Reinigungsmittelauslasses, the cleaning agent outlet covering the splash guard is provided.

The splash guard is designed according to a special feature of the invention as a lid. This is pivotable, which allows the user side to be able to swing it aside if necessary. In the pivoted state of the lid, access to the Reinigungsmittelauslass is possible. This makes it possible to remove any accumulated dirt and / or impurities manually in a simple manner. In addition, in the case of repair or maintenance, simplified access to the detergent outlet is possible.

The lid is held under spring force in its closing the Reinigungsmittelauslass closing position according to a further feature of the invention. An unintentional Beiseiteklappen the lid from its closed position into its open position is thus prevented. If the lid is to be manually pivoted out of its closed position into its open position, this has to be done counter to the spring force acting on the lid by the spring.

It is provided according to a further feature of the invention that the lid is arranged in its closing the Reinigungsmittelauslass closing position while leaving a gap spaced from the cleaning agent outlet. The lid is therefore not fluid-tight at the outlet opening of the detergent outlet. Rather, a spaced arrangement of the lid is provided relative to the outlet opening. Due to this spaced arrangement results in a gap between the lid on the one hand and detergent outlet on the other. This spaced arrangement affords the advantage that rinsing liquor located within the rinsing area in the intended use case of the dishwasher can flow into the volume area below the lid and can flow through the inside of the door of the cleaning agent outlet.

Thus, detergent dispensed by the metering device passes in the intended use case to the outlet opening, where appropriate on the inside or on the inside. If appropriate, this removal or attachment is further promoted by the lid provided according to the invention, which protects the outlet opening from the undesired ingress of soiling. Thanks to the spaced arrangement of the lid, it is now achieved that rinsing fluid circulated in the rinsing chamber can flow under the cover provided according to the invention and dissolve and remove any deposits or deposits of cleaning agents. Thus, the outlet and / or surrounding the outlet opening door-side edge region are always kept clean and free of any deposits.

For the purpose of the spaced arrangement of the lid carries according to a further feature of the invention on its inside a spacer extension. This is based in the closed position of the lid inside the door, whereby the dimensioning of the spacer extension defines the Spaltbelassung between cover and support point for the spacer extension.

According to a further feature of the invention it is provided that the cover carries on its inside a projecting in the closed position in the Reinigungsmittelauslass impact extension. This impact extension is used advantageously to flow in the intended use case in the gap between the lid and Reinigungsmittelauslass inflowing rinse directly into the detergent outlet. The rinsing fluid flowing into the gap between the lid and the detergent outlet is thus prevented from flowing past the lid on the inside of the lid. Rather, it is deflected in the direction of the inside door outlet opening of the detergent outlet by means of the impact extension, whereby the flushing of the outlet opening or the detergent outlet is supported.

It is provided according to a further feature of the invention that the detergent outlet is provided by a nozzle of the metering device, which projects into an opening of the Spülraumtür. Accordingly, the Spülraumtür has a fluidic breakthrough. In these, the metering device is used with a Dosiereinrichtungsseitigen nozzle. When used as intended, detergent supplied by the metering device passes through this nozzle into the washing compartment provided by the automatic dishwasher. The detergent outlet is thus provided by the nozzle of the metering device.

It is provided according to a further feature of the invention that the neck inside the door of the dishwasher door carries a frame.

The frame serves several purposes. On the one hand, it ensures a positional fixation and positioning of the inside wall-side nozzle section relative to the dishwasher door or the opening formed in the dishwasher door, through which the nozzle protrudes. On the other hand, the frame serves as a flow barrier with open Spülraumtür. Thus, the practice has shown that when the dishwasher door is open, dirt and / or residual liquids can accumulate inside the door, in particular when the dishwasher is loaded with the dish racks moved out in the intended manner. In this case, dripping or falling contaminants and / or contaminants are collected by the dishwasher door located in the open state to be cleaned. These then collect on the inside of the door of the Spülraumtüre and can flow into the door inner side outlet opening of the Reinigungsmittelauslasses in particular in a back swinging the Spülraumtür in the closed position or enter. The frame carried by the nozzle of the metering device effectively prevents this because it surrounds the outlet opening of the detergent outlet and thus forms a barrier protection for contaminants and / or impurities possibly located on the inside of the door of the dishwasher door.

According to a further feature of the invention, it is provided that the section of the frame which is assigned to the door edge is equipped with a closing surface which is inclined towards the inside of the door. This end face serves to allow rinsing water to flow in a simplified manner over the frame in the direction of the outlet opening. Thus, in the intended use case of the automatic dishwashing machine, rinsing liquor is dispensed via the spray arms of the spray device, which also impinges on the dishwasher door on the inside of the door. The rinsing liquor conducted in this way onto the inside of the door of the washing-room door flows on the inside of the washing-room door. The end face provided according to the invention has the advantage that it flows into the outlet opening region via the frame surrounding the outlet opening in the region of the outlet opening on the inside of the door. In the manner already described above, the removal or detachment of any detergent residues and / or any soiling is promoted, in particular in combination with the cover projection provided on the inside of the lid.

According to a further feature of the invention it is provided that the Spülraumtür door outside carries a diaphragm pivot. This panel is used in particular the privacy and covers in the pivoted state, the metering device provided outside the door. In the open state of the aperture, a user-side access to the metering device is permitted.
