Definitions

  • the invention relates to a detergent dosing system according to the preamble of claim 1. Furthermore, the invention relates to a water-carrying household appliance.
  • Most of the domestic dishwashers currently in use have an addition device for receiving one or more cleaning agents, which are added to the washing liquor in the course of a rinsing cycle for cleaning the items to be sorted in the dishwasher.
  • the cleaning agent stored in the addition device is completely dispensed into the washing compartment during the washing cycle and added to the washing liquor circulated therein.
  • the size of the addition device is such that just the amount of cleaning agent required for a rinsing cycle can be filled.
  • the user of the dishwasher is therefore forced to add the amount of detergent required for the washing cycle to the addition device at the beginning of each washing cycle. This handling is inconvenient for the user of the dishwasher.
  • Addition devices which add the amount of cleaning agents stored therein to the washing liquor at once do not allow more complex washing programs to be carried out. In certain situations, for example, it may be useful to add the detergent to the washing liquor at different times. Addition devices which are designed to take up a single detergent dose cannot support such complex rinsing cycles.
  • a dishwasher with a metering device for adding additives into the washing container is known, in which basic chemicals are accommodated separately in storage containers and can be added independently.
  • a water-carrying household appliance in particular a household dishwasher, has a detergent dosing system, the detergent dosing system having a detergent dispenser with a receiving space for receiving at least one cartridge, the cartridge being designed for storing at least one cleaning agent.
  • the quantity of detergent stored is greater than the quantity required for a rinsing cycle and the detergent dosing system has a device for detecting a fill level in the at least one cartridge.
  • the detergent dosing system for dishwashers can be designed to be arranged in the interior of the dishwasher, in particular adjacent to a washing compartment of the dishwasher.
  • the detergent dosing system contains detergents, the amount of detergent stored being greater than the amount required for a rinse cycle.
  • the detergent dosing system essentially provides exactly the amount of detergent that is necessary for a rinse cycle.
  • Detergents can be compositions of detergent components or individual detergent substances, such as an enzyme.
  • the cleaning agents can be liquid or gel-like.
  • the detergent dosing system can be designed to emit a signal when a fill level, for example a predetermined fill level, is detected.
  • the detergent dosing system has a plurality of separate chambers for the respective accommodation of detergents.
  • the device for detecting the predetermined fill level is designed to determine the fill level of at least one, but not all, of the chambers.
  • the detergent dosing system for dishwashers further comprises a second detection means for detecting the dosing processes that have been carried out since the full cartridge was inserted; and an evaluation means which determines the fill level of the cleaning agent in the cleaning agent dosing system from the information of at least the second detection means.
  • the cleaning agent dosing system uses an indirect procedure according to the first and the further variant according to the invention.
  • the first variant according to the invention not all of the chambers of the detergent dosing system are monitored for their fill level, but only the monitoring takes place in some of the chambers. On the basis of this determined information, the global level of detergent in the detergent dosing system can be concluded.
  • the device for detecting the predetermined fill level can also be designed for detecting the fill level of exactly one chamber. This procedure ensures an economical and inexpensive construction.
  • the detergent dosing system has a detergent dispenser with a receiving space for receiving at least one cartridge containing the detergents, and the device for detecting the predetermined fill level is formed in the detergent dispenser and / or the cartridge.
  • the device for detecting the predetermined fill level works according to an optical principle.
  • the device for the detection of a fill level has a light transmitter, a light receiver and a light guide, light radiation emitted by the light transmitter being able to be coupled into the light guide and light radiation emerging from the light guide being receivable by the light receiver, with an evaluation of the input and output values coupled light radiation can be checked whether the predetermined level is reached. The evaluation is based on a comparison of the light radiation that is coupled in and out.
  • the light guide has a first coupling surface and a second coupling surface, the light radiation from the light transmitter being able to be coupled in through the first coupling surface and the light radiation emerging from the light guide being able to be coupled out through the first or the second coupling surface.
  • the light transmitter and the light receiver can be designed as a structural unit.
  • the light guide can be designed, for example, as a rod, the reflection properties of the light guide being exploited.
  • the light transmitter and the light receiver are formed separately from one another.
  • the light guide can be used as a helix, for example be trained by which the light radiation is directed. In both cases, the different refractive properties are used when the light guide is surrounded by cleaning agents compared to a situation where the light guide is not or only partially surrounded by cleaning agents.
  • the light transmitter and the light receiver are arranged in the detergent dispenser.
  • the light guide is arranged in the cartridge in which the cleaning agent is located. With the cartridge inserted in the detergent dispenser, the light transmitter or light receiver and light guide are arranged with respect to one another in such a way that the light coupling and coupling out described above can take place.
  • a mechanism is preferably provided here, which ensures that the cartridge can only be inserted into the detergent dispenser in one way, so that the function of the detection device can be ensured. This can be done, for example, by mechanical coding on the cartridge, e.g. a projection and a corresponding recess on the detergent dispenser, and vice versa.
  • the device for detecting a fill level works according to a capacitive principle.
  • the device for detecting the predetermined fill level has a first and a second electrode with a dielectric arranged between the first and the second electrode, the first electrode being arranged in the cleaning agent dosing system in an electrically insulating manner by the cleaning agent and the second electrode and the predetermined level is determined by evaluating the voltage present between the first and the second electrode.
  • the second electrode is formed from an electrically conductive material and can be arranged on the outer wall of the cartridge or on a housing wall of the detergent dispenser.
  • the dielectric between the first and the second electrode is formed by the wall of the cartridge and / or the wall of the detergent dispenser and / or, if appropriate, an air gap.
  • the level at which the signal is to be emitted by the length of the extension of the light guide in the cartridge in the direction of gravity or by the length of the extension of the second electrode in the direction of gravity. In this way, it can advantageously be set whether a signal should be emitted when the cartridge is completely empty or at a point in time when a number m, preferably between 2 and 5, of dosing processes is still contained in the detergent dosing system.
  • the device for detecting the predetermined fill level works according to an acoustic principle.
  • the device for the detection of a fill level has an excitation means with which the cleaning agent can be set in vibration and an evaluation means with which the resulting noise pattern can be evaluated.
  • a generator operating according to the piezo-ultrasound principle can preferably be used as the excitation means.
  • the second detection means detects the number of dosing processes and / or the volume derived from the detergent dosing system. Based on these parameters, a precise determination of the fill level is possible. By permanently comparing a predetermined fill level with the calculated fill level, the decision can be made as to whether to issue the signal which signals to the user that an exchange of the cartridge is necessary or is imminent.
  • the detergent dosing system is provided with a transponder in one embodiment, the information stored in the transponder being readable by the first detection means for further evaluation.
  • the cartridge can be provided with a code, in particular a bar code, for recognizing the new or full cartridge, the one in the Transponder stored information can be read out by the first detection means for further evaluation.
  • the first detection means has a receiving device which can read out the information stored in the transponder as it approaches the receiving device.
  • the system can work in a passive manner, ie the transponder attached to the cartridge does not require an independent energy supply. The energy required for reading is supplied to the transponder by the receiving device as soon as it is in its working area.
  • the first detection means can have a bar code reader which is arranged in the detergent dosing system, so that the information contained in the bar code is read out automatically as soon as the cartridge is inserted into the detergent dosing system.
  • the bar code reader can also be arranged on another assembly of a dishwasher, so that, for example, the user must guide the cartridge past the bar code reader before inserting the cartridge into the detergent dosing system.
  • a structurally particularly simple construction of the device for detecting a predetermined fill level of the cleaning agent is obtained if the volume of the cleaning agents stored in the plurality of chambers is dimensioned such that a total of z rinsing cycles can be carried out and each of the cleaning agents is used up with the zth rinsing cycle is.
  • This procedure ensures that the cartridge no longer contains any cleaning agents when it is replaced.
  • This state is achieved in particular in that, according to a development of the invention, an equal percentage of the at least two cleaning agents is dosed by the dosing system in each wash cycle. It can be provided that the total number z of rinsing cycles when several cartridges are used up can be variable and is dependent on the rinsing cycles carried out in each case.
  • This variant ensures that, regardless of the number of chambers that store cleaning agents, a single device for detecting the fill level (one of the chambers) is sufficient to reliably provide information about an empty cartridge or about a still possible number of dosing processes ,
  • the invention also includes a detergent dosing system of the type described above.
  • Fig. 1 shows a dishwasher 1 which has a door 3 pivotably mounted on a housing 2. The door 3 is shown in the figure in its open position. Dishware baskets 5, 6 are arranged in a known manner in a wash cabinet 4 which can be closed by the door 3.
  • a detergent dosing system 10, comprising a detergent dispenser 11 and a cartridge 50 according to the invention, which contains at least two detergents stored separately from one another, is arranged in a container wall 7 of the housing 2.
  • Fig. 1 shows the preferred arrangement of the detergent dosing system 10 between the upper basket 5 and the lower basket 6.
  • the detergent dispenser 11 which receives the cartridge 50 is arranged in a section of the container wall 7 close to the door opening in order to introduce it and removing the cartridge 50 into or out of the detergent dispenser 11 for the user.
  • the detergent dispenser 11 comprises a housing 12 and a cover which is pivotably mounted relative to the housing 12. If the lid is in its open position (see illustration in Fig. 1 ), the cartridge 50 can be inserted into the lid from the wash cabinet 4.
  • the cover has, for example, two symmetrically arranged holding tabs which have an L-shaped shape and are adapted to the size of the cartridge 50, so that the holding tabs grip around the cartridge 50 after insertion (not shown).
  • a support surface is also formed on the cover, so that the cartridge 50 comes to rest in a defined position.
  • Fig. 2 shows another dishwasher 1 with a detergent dosing system 10.
  • the detergent dosing system 10 more precisely the detergent dispenser 11 is arranged in the door 3 of the dishwasher.
  • the detergent dispenser 11 is loaded with the cartridge 50 from the front 8 of the door.
  • the opening for loading the detergent dispenser 11 can be arranged in the area of a cover of the dishwasher or the inside door of the door.
  • the advantage of the arrangement according to Fig. 2 consists in a more convenient insertion and removal of the cartridge for the user.
  • FIG Fig. 3 An exemplary embodiment of the cartridge 50 is shown in FIG Fig. 3 shown.
  • the cartridge 50 has, by way of example only, five chambers 51a, 51b, 51c, 51d and 51e, each for receiving a cleaning agent or a cleaning agent mixture.
  • the size of the individual chambers 51a to 51e is dimensioned in accordance with the volume required during a predetermined number of dosing processes.
  • the volume of the different cleaning agents in the chambers 51a to 51e is dimensioned such that after a certain number of dosing processes, preferably between 20 and 40, more preferably approx. 30, all of the chambers 51a to 51e are emptied simultaneously and essentially completely.
  • the total number of dosing processes when the cartridge is used up depends on the type of rinsing cycle carried out. In order to meet the different requirements, a certain dosing quantity is specified for each program that can be selected in the dishwasher, or it is determined by sensors. In the case of lightly soiled wash items, a lower dosage is selected, while in the case of heavily soiled wash items, a higher amount of detergent is provided. To ensure that each of the detergents with the same rinse cycle is used up, the percentage of each detergent component that is added to the rinse liquor during a dosing process is the same. This enables economical use of the available resources, since the cartridge can only be replaced when it is completely empty.
  • the cleaning agent can only be conveyed using gravity.
  • the conveying device in particular the configuration of the seal, can also be constructed according to the principle of a pump, so that cleaning agents are conveyed from the cleaning chamber into the metering chamber and from the metering chamber into the washing area.
  • Each of the chambers 51a to 51e is provided with an openable closure 25a to 25e, e.g. provided in the form of a membrane.
  • the e.g. Membranes made of rubber seal off the individual chambers 51a to 51e so that no cleaning agent can escape from the cartridge 50 during storage and transportation.
  • the membranes are pierced by cannulas 21 correspondingly arranged in the detergent dispenser 11, so that detergent can be added to the washing compartment in accordance with a corresponding metering device.
  • the cartridge is preferably made of a plastic and has a width B of approximately 200 mm, a height H of approximately 125 mm and a depth of approximately 25 mm. With these dimensions, the volume of the various chambers can be dimensioned such that the desired 20 to 40 rinsing cycles can be carried out by means of a cartridge.
  • the cartridge 50 has a further chamber 52 which is connected to one or more ventilation channels 53.
  • the ventilation channel or channels 53 in turn have a connection to the various chambers 51a to 51e. This ensures that with increasing emptying of the chambers 51a to 51e no negative pressure can build up in them, which would make the addition of cleaning agents more difficult or falsified.
  • the ventilation channels 53 are preferably located in a cover 54, which is applied to the housing of the cartridge after the individual chambers 51a to 51e have been filled with the respective cleaning agents.
  • the cover 54 can have a pressure relief valve 55, which may be necessary for certain detergent components.
  • the detergent dosing system has means to query the fill level of the detergent in the cartridge. If the cleaning agent reaches a predetermined fill level in one or more of the chambers of the cartridge, e.g. if a predetermined number of rinsing cycles is still possible, this can be displayed to the user via an optical signal.

  • a light guide 62 for example made of plastic or glass, is fastened in the housing base of the cartridge 50. Is the cartridge 50, as in Fig. 4 shown, inserted in the detergent dispenser 11, a first coupling surface 63 of the light guide 62 (which is flush with the bottom of the housing of the cartridge 50) adjoins the light guide element 61. In this way, light emitted by the transceiver 60 can be coupled into the light guide 62.
  • the injected light radiation is reflected on a second coupling surface 64 of the light guide 62 and is fed back to the light receiver via the coupling surface 63.
  • An evaluation, in particular a comparison, of the light radiation that is coupled in and out can determine whether the second coupling surface 64 is located within the cleaning agent or outside of it. In these two cases there are different refractive properties on the second coupling surface 64, which can be easily detected by an evaluation unit.
