Definitions
- the invention relates to a household dishwasher with a housing in which a 5 washing container is arranged and with at least one metering device arranged inside the housing for program-controlled addition of an active ingredient into the washing container.
- the invention relates to a method for dosing detergent and bleach into the rinsing container of a household dishwasher with a housing and with at least one dosing device arranged inside the housing for separate storage and delivery of the liquid or pasty detergent and the liquid or pasty bleach, the metering device is equipped with storage containers which have a capacity which goes beyond the amount of cleaning agent or bleaching agent required for a single rinsing process, and the
- Dosing systems are suitable for storing a large amount of liquid rinse aid, with a fraction of this amount being dosed into the rinsing container in each washing program.
- metering systems are known (DE 199 28 040 A1), in which liquid post-treatment agents can also be stored.
- Tablets are filled for one rinse cycle and which of the
- DE 195 11 789 A1 discloses a washing machine or dishwasher with a metering chamber.
- the dosing chamber has a variable volume.
- the invention therefore presents the problem of disclosing a household dishwasher of the type mentioned at the outset, which enables larger quantities of detergent to be stored and thus, if appropriate, their automatic metering.
- this problem is solved in that the metering device is designed for separate storage and dispensing of a liquid or pasty cleaning agent and a liquid or pasty bleaching agent, the metering device for this purpose having storage containers
- the invention also has the problem of disclosing a method for metering such a cleaner, in which the refilling process is simplified. According to the invention, this problem is solved in that the cleaning agent and the bleaching agent are metered in amounts in a washing program, the ratio of which to the ratio of
- Bleaching component has the advantage that they can be added at different times and in different quantities and then develop their optimal effect in the respective program section.
- the storage containers are arranged in the upper region of an appliance door closing the washing container. This makes filling them easier.
- the storage containers are thermally insulated from the rinsing container. This prevents the components from being exposed to the temperature fluctuations in the rinsing container, which could impair their effectiveness.
- metering chambers are connected to the reservoir, the transition openings between the reservoir and metering chamber being separable from one another by first sealing elements. By opening these sealing elements, a defined amount is then let into the metering chambers, which is then emptied by opening second sealing elements through outlet openings in the metering chambers. It is particularly advantageous if the first and second sealing elements are each coupled to one another in such a way that closing a transition opening causes opening of an outlet opening and opening a transition opening causes closing of an outlet opening. This will become
- Movement of the first and second sealing elements per reservoir only requires one actuator. There is even the possibility of coupling the sealing elements of both storage containers to one another and thereby saving an additional actuator. However, this has the disadvantage that a dispensing of the two components that is independent of time or quantity has to be dispensed with.
- the sealing elements can expediently be moved by an electric motor or electromagnetically.
- the second sealing elements are arranged in the area of impact of the liquid jet. This achieves cleaning of the sealing elements and thus ensures their sealing fit.
- the capacity of a metering chamber is a fraction of the maximum metered amount in a washing program
- Amount of active ingredient As a result, by actuating the metering device several times, a variable amount of active substance, for example the degree of soiling of the dishes, the degree of filling and / or the particular washing program selected, can be supplied to the washing process.
- the storage containers have different capacities. This can take into account the fact that less bleaching agent than cleaning agent is required in a rinsing process. This is where the method for dosing detergent and bleaching agent according to claim 11 comes in.
- An embodiment of the invention is shown purely schematically in the drawings and is described in more detail below. It shows
- Figure 2 shows a cross section through the upper region of the appliance door
- Figures 3a, b the dosing device for cleaning and bleaching agents as a detail during
- FIG. 1 the front of a household dishwasher 1 is shown.
- This has a rinsing container 2 in a known manner, which is opened to the front and can therefore be closed by a pivoting appliance door 3.
- the figure shows the machine with the door 3 closed, which is why the rinsing container 2 located behind it, indicated in FIG. 2, is not visible in FIG. 1.
- the upper area of the door 3 can carry a control panel 4, in which there are then rotary selection switches 5 and / or pushbuttons 6 for selecting a program and also display devices 7 for displaying user information.
- the device control 8 and further electrical and electronic components are arranged in the interior of the control panel, which is symbolized by the dashed box.
- the door 3 is formed from an outer door panel 9 and an inner door panel 10.
- Inner door panel 10 is provided with a beveled edge 11, so that
- a further metering device 15 is arranged.
- the further metering device 15 is suitable for program-controlled delivery of liquid or pasty cleaning agent 16 and liquid or pasty bleaching agent 17 (see FIGS. 3a and b).
- the active ingredient components are stored separately from one another in two different containers 18 and 19.
- the components enzyme / alkalinity and bleaching agents which are incompatible with one another in liquid and / or pasty formulations, are only mixed in the rinsing tank and can develop their full effect there.
- the further metering device is provided as a supplement to the combination metering device 13, so that the user can choose between conventional powder or tablet cleaner and liquid components.
- a less convenient embodiment can do without the combination metering device 13, in which case the
- Dosing device 15 must be expanded by a chamber for rinse aid (not shown).
- the metering device 15 consists of the two storage containers 18 and 19 with integrally formed metering chambers 20 and 21, each of which is assigned a closure device 22 and 23, respectively. It can be manufactured as a one-piece plastic component, a common housing 24 then being divided into the two containers 18 and 19 by means of a partition wall 25. Alternatively, a separate construction of both containers 18 and 19 is possible.
- the metering device 15 is inserted into the cavity 12 between the outer plate 9 and the inner plate 10.
- the storage containers 18 and 19 are surrounded at least on the side facing the washing container 2 by a thermal insulation layer 26. Alternatively, all container walls can be made of a heat-insulating material (not shown).
- the outlet openings 27 and 28 for metering the media 16 and 17 are designed as channels 29 (see FIG. 2), which penetrate the inner door panel 10 approximately at the level of the access flaps 30 to 32 of the salt vessel 14 and the combination metering device 13.
- the filling openings are also designed as channels 33 and project through the folded edge 11 of the inner door panel 10, so that the containers 18 and 19 can be filled easily when the appliance door 3 is slightly open. A mechanism not shown in the drawings can ensure that the Door is held in this slightly open position, so that the user has both hands free to fill.
- the closure devices consist of plungers 34 and 35, the rods 36 and 37 of electromagnets 38 and 39, respectively, between a first position and one shown in FIG. 3a
- Dosing chambers 20 and 21 can be closed, as shown in FIG. 3b.
- the lower ends 34.2 and 35.2 are also rounded and form lower sealing surfaces with which the upper entrances of the channels 29 and thus the outlet openings 27 and 28 to the washing container 2
- the storage container 18 is opened toward the metering chamber 20 and consequently the metering chamber 20 is filled.
- the plunger 34 is then raised to carry out a dosing process, so that the upper sealing surface 34.1 closes the transition opening 40 and prevents the medium 16 from running into the dosing chamber 27.
- the lower sealing surface 34.2 is thereby removed from the channel entrance and exposes the outlet opening 27.
- the outlet openings 27 and 28 should be placed in such a way that they are struck by a spray jet through one of the spray arms (eg the middle one, not shown), whereby there is the possibility that the spray jets can clean the sealing seat between the outlet and the metering chamber 20 or 21 .
- the spray jets can even partially wash out the dosing chamber 2 5 20 or 21.
- FIGS. 3a and b it can be seen that the right reservoir 19 for bleach 17 and the right metering chamber 21 have a smaller volume than their left neighbors. The reason for this is the fact that smaller amounts of bleach 17 are used as cleaning agents 16 for a rinse cycle.
- metering chambers 20 and 21 and storage container 30 18 and 19 dimensioned such that the ratio of the two storage containers 18 and 19 corresponds exactly to the ratio of the metering chambers 20 and 21 and is also in each
- the dosing chambers 20 and 21 are also dimensioned so that their capacity is only a fraction of the maximum amount of active ingredient added in a washing program. In this way, such a fraction can be dosed several times in the course of a washing program. There is then the possibility, on the one hand, of varying the metered amount of detergent, either as a function of the set program and / or as a function of sensor-determined parameters of the wash ware and / or the wash liquid. So that the
- Partial quantities are supplied to the washing container at different times in the washing program. To reduce the cleaning or bleaching power due to aging
- higher dosages can also take place with decreasing fill level of the storage containers 18 and 19.
- at least one level sensor (not shown in the drawings) or a device for detecting a container vacancy or a container filling is necessary, with the latter additionally having to count the number of doses already made.
- the dosing mechanism must be able to ensure a safe entry and exit from the dosing chamber 20 or 21 2s for all viscosities . This can be done by the following, used individually or in combination
