Definitions

• the invention relates to a water-conducting household appliance according to the preamble of patent claim 1.
• Dishwashers usually have a pressure-regulating means, which ensures in the case of a, occurring in the rinse tank, overpressure for pressure equalization.
• the pressure regulating means may be formed, for example, as a valve.
• the pressure regulating means can open, whereby the resulting pressure inside the washing container is reduced.
• This pressure-regulating means which is also referred to as device ventilation, is usually connected to a line system which is connected to the rinse tank.
• the introduction of a specially provided for the pressure regulating agent opening in the washing is, however, undesirable from a production point of view and for cost reasons.
• the detergent dosing system is designed to produce an expansion opening between the washing compartment and the environment for forming one.
• the detergent dosing system can be designed to be arranged adjacent to the washing compartment of the dishwasher in the interior of the dishwasher.
• the detergent dosing system is for receiving at least a cleaning agent is formed, wherein the stored amount of cleaning agent is greater than the amount required for a rinsing cycle.
• the detergent dosing system provides substantially the exact amount of detergent needed for a rinse cycle.
• Detergents may be compositions of detergent components or individual detergent substances, such as an enzyme.
• the cleaning agents may be liquid or gel.
• the cleaning agents may be arranged in a plurality of chambers of the cartridge. However, it can also be provided that the detergent dosing system is designed to accommodate a corresponding number of cartridges with only one chamber
• the integration of the expansion opening in a makesffendosiersystem has the advantage that the washing container of the dishwasher can be structurally simpler structure. In particular, it is no longer necessary to provide separate openings for providing an expansion opening and for integrating an adding device or a detergent dosing system. As a result, manufacturing steps can be omitted, as a result, a more cost-effective dishwasher can be provided. In particular, this simplifies the routing, which can be made shorter compared to conventional dishwashers. By reducing the openings to be introduced into the washing container, the number of openings to be sealed is also reduced.
• the detergent dosing system can be connected to a piping system that connects to an environment of the dishwasher.
• the conduit system runs, for example, in a known manner in the intermediate space extending between the washing container and an outer wall of the dishwasher.
• the detergent dosing system has, according to a further embodiment, at least one opening facing the washing compartment.
• This opening preferably opens into a chamber of the detergent dosing system, which is provided for receiving solid cleaning agents, wherein the at least a chamber establishes the operative connection between the washroom and the environment.
• the provision of the chamber for a solid detergent has the advantage that the operation of the dishwasher can be ensured even if the usually filled in the detergent dosing system detergent, which can be kept in a cartridge, for example, tends and the owner no further filled Cartridge on hand has.
• the construction is simplified because the opening forming the operative connection between the washing compartment and the environment does not interfere with a separate covering means, e.g. a lid needs to be provided. The penetration of water into the opening can be taken into account solely by constructive design or arrangement of the opening in the chamber.
• the at least one chamber is not closed by a closure element, such as e.g. a lid, is closed.
• the detergent dosing system is arranged according to a variant in a side wall of the washing compartment, for example. Between an upper basket and a lower basket of the dishwasher. This facilitates the filling of the detergent dosing system with cleaning agents and possibly other operating materials for the user, for example when the door is open. However, other positions are also possible for the detergent dosing system, such as e.g. a back wall or a ceiling of the sink.
• the detergent dosing system has a detergent dispenser with at least one receiving space for at least one cartridge which can be inserted into the receiving space in an operating state, for example when the door is open.
• the detergent dosing system thus comprises as main components a detergent dispenser stationarily arranged in the dishwasher and at least one cartridge containing at least one detergent, ie a cartridge can contain only one detergent stored in a chamber or a plurality of chambers for one corresponding number of cleaning agents.
• the cleaning agents may be individual cleaning substances or combination products of cleaning substances.
• the cartridge preferably has at least two chambers, one for a cleaning agent and one for a rinse aid. The storage by means of the cartridge facilitates handling for the user.
• a device which detects the occupancy of the at least one chamber with a solid detergent and emits a signal characterizing this state to a controller of the dishwasher.
• the detergent dosing system has at least one outlet, which is in operative connection with the rinsing chamber, via which a defined quantity of rinsing agent detergent can be supplied during a rinsing cycle.
• the at least one outlet may be provided on the detergent dispenser. It is also conceivable that the at least one outlet is arranged on the cartridge. It is expedient if the at least one outlet is provided on the housing section of the detergent dispenser, which is arranged in the direction of gravity below the receiving space.
• the number of outlets is basically arbitrary. There may be provided a number of outlets corresponding to the number of detergent stored in the cartridge or the number of detergent receiving chambers of the cartridge. By the latter variant prevents detergent components in a single outlet to a in Mix detergent mixture with unfavorable or unforeseen effect.
• the at least one outlet of the detergent dosing system opens into a dosing chamber which is in operative connection with the cleaning agent.
• a conveying device with which the cleaning agent from the cartridge can be supplied to the washing container.
• FIG. 2 shows a top view of a detergent dosing system according to the invention for arrangement in the container wall of the dishwasher
• FIG. 3 shows a cross section through the detergent dosing system shown in FIG. 3, and FIG
• FIG. 4 shows an exemplary embodiment of a cartridge for use in a detergent dosing system according to the invention.
• Fig. 1 shows a dishwasher 1 according to the invention, which has a pivotally mounted on a housing 2 door 3.
• the door 3 is shown in the figure in its open position.
• Spülraum 4 dish racks 5, 6 are arranged in a known manner.
