Definitions

  • the invention relates to a water-conducting household appliance according to the preamble of patent claim 1.
  • the majority of, for example, currently in use household dishwashers has an adding device for receiving one or more cleaning agents which are added in the course of a rinsing cycle of the rinsing liquor for cleaning the sorted in the dishwasher items to be washed.
  • the detergent stored in the adding device is completely discharged into the washing compartment during the rinsing cycle and mixed with the rinsing water circulated therein.
  • the addition device is sized in size so that just the required amount of detergent for a rinse cycle can be filled. The user of the dishwasher is therefore forced to fill in the adding device the amount of detergent required for the rinse cycle at the beginning of each rinse cycle. This handling is inconvenient for the user of the dishwasher.
  • such dishwashers have the problem that the amount of cleaning agent introduced into the adding device may vary from user to user, but also from one rinse to another.
  • an incorrectly metered amount of cleaning agent can lead to unsatisfactory scavenging results if the cleaning agents have been dispensed too low and, on the other hand, a waste of cleaning agents and thus environmental pollution if too large an amount of cleaning agent has been dispensed.
  • Addition devices which add the amount of cleaning agents stored therein at once to the rinsing liquor still do not permit the implementation of more complex rinsing programs. Thus, it may be useful, for example, in certain situations, to meter in the detergent at different times of the wash liquor. Addition devices configured to receive a single detergent dose can not support such complex rinse cycles.
  • the WO 2005/058126 A1 shows individual or contiguous reservoir 4, 5, 6, 7, 8, which may each be provided with an integrated micropump 9, which, however, means a high design effort and brings in operation the risk of malfunction by gluing or abrasion with it. Even without a pump a gravity-driven emptying should be possible. In this case, however, it would then have to be worked against a vacuum that becomes increasingly more intense during emptying, which makes emptying more difficult and, in particular, a hindrance to uniform metering over many rinses.
  • the WO 2005/100675 A and US 2004/122555 show outside attachable to a dishwasher devices that make no contribution to solving the problem of the invention for reasons of space. It is an object of the invention to provide a water-conducting household appliance that can perform complex rinsing cycles. It is another object of the invention to provide auxiliaries for this purpose.
  • a water-conducting domestic appliance in particular a domestic dishwasher, has a detergent dosing system which has at least one detergent dispenser for receiving at least one cartridge, wherein the Cartridge has separate chambers for storing at least two cleaning agents
  • the invention is characterized in that the amount of cleaning agent stored in each chamber is greater than the amount required for a rinsing cycle.
  • the detergent dosing system for receiving the cartridge provides in a rinse cycle substantially exactly the amount of detergent necessary 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 in chambers of the cartridge.
  • the detergent dosing system is designed to accommodate a corresponding number of cartridges with only one chamber.
  • the storage of different cleaning agents in different chambers has the advantage that in a certain section of a rinsing cycle only that cleaning agent needs to be added, which is actually necessary for this rinsing section.
  • several of the cleaning agents can be added simultaneously. If two different cleaning agents are generally added simultaneously to the rinsing liquor during a rinsing cycle, it is also possible to arrange these cleaning agents in a common chamber of the cartridge.
  • a ventilation chamber is provided, which is in operative connection with the chambers containing the detergent.
  • the ventilation chamber is in this case via ventilation channels in a common, the individual chambers final, lid with the detergent containing chambers in combination. In this way, it is ensured that with increasing emptying of the chambers, no negative pressure can build up in them, whereby the addition of detergents to the rinsing liquor would be difficult or possibly would take place in the wrong amount.
  • the ventilation chamber is preferably part of the cartridge. It is preferably provided that the detergent dispenser is arranged in an interior of the water-bearing household appliance.
  • the receiving volume of the chambers for receiving at least two cleaning agents is dimensioned such that between 20 and 40, preferably 30, rinsing cycles are feasible.
  • the cartridge separate chambers for storing more than 2 and less than 10, preferably 7 cleaning means are provided.
  • the targeted addition of, for example, complexing agents allows an adjustment of the water hardness, so that a dishwasher according to the invention can be designed without water softening device.
  • the adjustment of the water hardness can be sensor-controlled or manually by an operator.
  • an adaptation of the added substances to the length of a selected cleaning program can take place.
  • the respective chambers are located in a common housing of the cartridge, i. Cartridge housing arranged, resulting in a particularly easy handling for the user.
  • a further embodiment provides that the cartridge is provided with at least one openable closure which, when inserted into the detergent dosing system, in particular automatically, can be opened and, in particular, automatically closes when the cartridge is removed from the detergent dosing system.
  • the openable closure may be formed, for example, by a membrane. During storage and transport, the closure ensures that the detergent stored in the cartridge can not leak unintentionally.
  • the closure is opened at the moment in which the cartridge is inserted into the detergent dispenser of the detergent dosing system, so that a metered addition of the detergent to the rinsing liquor is possible during the further operation of the dishwasher.
  • the number of closures may vary.
  • a number of closures is provided corresponding to the number of chambers of the cartridge.
  • the number of closures may also correspond to the number of cleaning agents in the cartridge.
  • the openable closure can eg be arranged in the direction of gravity at the bottom, ie at the bottom of the cartridge, when the cartridge is in the installed position in the cartridge Detergent dosing system is located. As a result, the complete emptying of the cartridge is facilitated by the conveyor, whereby no detergent remains unused in the cartridge.
  • a further embodiment provides that the cartridge has at least one conveying device with which the at least two cleaning agents can be conveyed into the washing compartment of the dishwasher.
  • This procedure has the advantage that the detergent dispenser of the detergent dosing system according to the invention can be made structurally particularly simple.
  • the necessary devices for metering the detergent held in the cartridge into the washing compartment are held exclusively in the cartridge according to this embodiment. It can be provided that a number of the detergent or chambers corresponding number of conveyors is provided.
  • the dispensing of the at least two cleaning agents takes place by way of gravity and in a further variant by establishing an outflow time in which the at least two cleaning agents can be diverted from the cartridge for further processing via the openable closure.
  • the openable closure of the cartridge in the direction of gravity is compulsorily arranged at the bottom when the cartridge is in the installed position in the detergent dosing system.
  • the flow time is adjusted according to this variant after each dosage or after each rinse cycle. This procedure ensures that, regardless of the amount of cleaning in the cartridge, the same volume of rinsing fluid is always added to a particular rinse program.
  • the above formula takes into account the influence of gravity and the volume of detergent contained in the cartridge, and thus the speed of leakage when the cap is open.
  • the dosage of the at least two cleaning agents by a pump or other actuator vorappelbar is a pump or other actuator vorappelbar.
  • the housing of the cartridge has a mechanical coding, e.g. a projection corresponding to a corresponding recess of the detergent dosing system.
  • the coding is designed such that the cartridge can be inserted into the detergent dispenser in only one way - the predetermined manner.
  • the cartridge may have any suitable shape.
  • the housing of the cartridge has a longitudinal extent along a main axis.
  • This may be e.g. a quarter-shaped body with a longitudinal axis, for example, along the width, act, which is much longer than all other axes (along the depth and the height).
  • it may also be a cone, truncated cone, cylinder, pyramid or truncated pyramidal basic body with a major axis.
  • the major axis is longer than minor axes of the housing with one of the above basic shape of the cartridge, for example by a factor of at least 1.5.
  • the base body may preferably have an extension along a first minor axis, eg along the height, and an extension along a second minor axis, eg along the depth, the extension extending along the first minor axis is substantially longer than the extension along the second minor axis, for example by a factor of 3 to 10, preferably 5.
  • a particularly good handling of the cartridge and a suitable volume of respective cleaning agent arise when the housing of the cartridge has a quarry-shaped basic shape has a depth of about 25 mm, a width of about 200 mm and a height of about 125 mm.
  • the preferred total number z of rinsing cycles between 20 and 40, preferably 30, rinsing cycles can be realized with such dimensions.
  • the chambers of the cartridge along the main axis are arranged side by side. That is, in a cartridge having a square basic shape and extending in the direction of the main axis, the division into chambers leads to chamber dimensions in which the dimension of a chamber is the number of chambers corresponding proportion of the width, while for all chamber an equal depth and Height is given.
  • At least one section of the cartridge directed towards the washing compartment of the water-conducting domestic appliance, when it is arranged in the detergent dosing system has a thermal insulation which limits a heat flow from the washing compartment in the direction of the detergent dosing system.
  • this procedure ensures the long-term stability of the detergent stored in the cartridge.
  • cleaning agents can be used, which have temperature-sensitive substances.
  • the thermal insulation prevents or limits excessively high temperature fluctuations of the detergent stored in the cartridge. This procedure is particularly advantageous if the stored amount of cleaning agent is designed for a very large total number of flushing cycles.
  • the heat insulation in the section of the cartridge directed towards the dishwasher washing compartment can be formed by a gas volume arranged in the section.
  • Manufacturing of the housing body from a plastic material is possible by the gas internal pressure method (GID) known from the prior art, in which a gas cavity is enclosed in the section made of a sprayable material, eg plastic.
  • the insulation may also be formed by a solid or liquid insulator material disposed in the section. This Insulator material may be present in addition to the material of the housing portion of the cartridge.
  • the housing portion may also be formed by the insulator material. There are also combinations of said materials conceivable.
  • the cartridge may further comprise a means for level measurement of the volume of detergent contained in the cartridge.
  • the means for level measurement may be configured in a variant for emitting a signal when the detergent contained in the cartridge is completely used up. As a result, the user of the dishwasher is signaled that an exchange of the cartridge for proper operation of the dishwasher is already necessary for the next rinse cycle.
  • the means for level measurement for the delivery of a signal is formed when the cleaning agent contained in the cartridge is sufficient to carry out a predetermined number m of rinsing cycles.
  • the number m of rinsing cycles can in principle be chosen arbitrarily, m being preferably chosen between 2 and 5.
  • the user of the dishwasher will be shown a future necessary replacement of the cartridge. However, the user is still able to operate the dishwasher for a certain number of rinse cycles, so there is still time to procure a new cartridge.
  • the means for level measurement in only one of the chambers of the cartridge is arranged to determine the level of the detergent of this chamber.
  • the statement about the level of a single of the chambers is sufficient to close the level of the entire cartridge, since the volume of detergent in the respective chambers is such that each of the detergents in the chambers is used up with the zth rinse cycle and in each rinse a percentage equal to the proportion of at least two detergents is metered by the dosing. This procedure allows for a low cost of the monitoring means an accurate prediction of the level of respective detergent in the cartridge.

  • the total number of rinsing cycles when the cartridge is consumed depends on the type of rinsing cycles performed in each case. In order to meet the different requirements, for each selectable in the dishwasher program a certain dosage is specified or determined by sensors. For weakly soiled dishes, a lower dosage is selected, while for heavily soiled items a higher dosage of cleaning agents is provided. To ensure that each of the detergents is used up with the same rinse cycle, the percentage of each detergent component added to the rinse liquor during a rinse cycle is the same. This allows an economical use of the available resources, since an exchange of the cartridge takes place only when it is completely emptied. In addition, this procedure makes it easier to sense the level, since it is sufficient To sense the level in only one of the chambers of the cartridge to obtain information about the filling state of the entire cartridge.
