Definitions
- the invention relates to a dishwasher, in particular a domestic dishwasher and a method for operating a dishwasher, in particular a domestic dishwasher.
- a ceiling spraying device e.g. in the form of a ceiling spray arm, a roof shower or a roof gyro, and / or an upper basket spray device, e.g. be used in the form of a top basket spray arm.
- a lower basket spray device e.g. used in the form of a arranged in the bottom region of the washing compartment lower basket spray arm.
- the supply of the spraying devices with the rinsing liquid via supply lines, wherein a pump, for example a circulating pump, feeds the rinsing liquid into the supply lines.
- the supply lines lead the rinsing liquid, which is conveyed by the pump, to the spray devices, from which the rinsing material in the racks is exposed to rinsing liquid.
- a distribution unit e.g. in the form of a water diverter, which allows a separate supply of water to the individual spray devices or even a group of spray devices.
- DE 10 2005 061 806 A1 discloses a dishwashing machine with a rinsing container, devices for rinsing dishes by means of rinsing liquor, a pump for circulating the rinsing liquor and a detection means for detecting foam formation in the rinsing liquor in a subprogram step "rinsing", in which If a foaming of the foam formation determined by the detection means can be counteracted by means, in particular a rinsing bath temperature can be increased.
- the object of the invention is to provide a dishwasher, in particular domestic dishwasher, with at least two spray devices which can be supplied separately with rinsing liquid and a method for operating such a dishwasher, in which foaming in the rinsing liquid is suppressed effectively and with simple means and thus in a cost-saving manner.
- a dishwasher comprises a rinsing container for receiving items to be cleaned, at least two spray devices arranged within the rinsing container for applying washing liquid to rinsing liquid, a pump, in particular a circulating pump, for conveying rinsing liquid to the spraying devices, a distribution unit controlled by a control unit for distribution - len of the pumped irrigation fluid to a single or a group of spray devices, wherein adjusts a volume flow of the rinsing liquid in dependence on the distribution of the rinsing liquid on the spray devices.
- the dishwasher has a detection device for detecting foaming in the rinsing liquid.
- the control unit controls the distributor unit in such a way that the distribution of the rinsing liquid on the spray devices changes in such a way that the tendency for foam formation to decrease.
- the invention is based on the basic idea that the tendency to foaming by a changed distribution of the rinsing liquid to the individual sprayers due to the thus changed fluid paths and / or the resulting changed impact characteristics of down-flowing rinsing liquid on the bottom or screen portion of the rinse, active can be influenced. So can be reduced by a simple change to another spray the tendency to foam or even eliminated completely.
- Such operating phases thus act in terms of foaming as calming phases in which no new foam is formed and in which the already existing foam degrades again.
- the distributor unit is controlled by the control unit upon detection of foaming in the rinsing liquid such that a volume flow of the rinsing liquid which is reduced in comparison to a current volume flow is also established.
- the pump sucks in air, which is thus fed into the rinsing liquid circuit.
- an excessively high proportion of air promotes foaming, in particular in conjunction with a high dirt concentration and / or a rinse aid mixed with the rinsing liquid.
- the operation with Reduced flow thus also represents a kind of calming phase, in which no new foam formed and in which the existing foam decreases again.
- the reduction of the volume flow of the rinsing liquid is achieved in a particularly simple and thus cost-effective manner that with the aid of a distribution unit, for example in the form of a water diverter, a change to another spray device is made in the loading of rinsing automatically adjusts a lower flow rate ,
- the lower volume flow can result, for example, from a smaller number of outlet openings for the rinsing liquid and / or reduced diameters of the outlet openings at the spray devices.
- the different installation height of the individual spray devices and / or different cross-sections of the supply lines have an effect on the respectively adjusting volume flow.
- a change in other operating parameters, such as the pump speed can be made to further support the foam suppression, but is generally not required.
- the invention can be used in dishwashers, in which an alternate feeding of individual spray devices or groups of spray devices with rinsing liquid is provided anyway.
- the suppression of foam formation according to the invention even makes it possible, in an operating mode with a maximum volume flow, eg in lower basket operation, in which the rinsing liquid exclusively distributes to a lower basket spraying device, to allow a predeterminable amount of air bound into the rinsing fluid circuit.
- the activation of the distributor unit according to the invention when foam formation is detected ensures that in good time before the delivery pressure and thus the delivery rate of the pump to another mode of operation, eg upper basket operation and / or ceiling operation, have a lesser tendency to foaming and possibly also a reduced volume flow is changed.
- the detection device comprises a sensor which detects at least one operating parameter of the pump or of a drive unit associated with the pump, eg in the form of an electric motor, wherein the at least one operating parameter is dependent on a proportion of foam in the conveyed rinsing fluid , Foaming in the rinsing liquid can then be detected in this case.
- the at least one operating parameter or a variable derived therefrom reaches a predefinable limit value.
- the pump speed and / or the pump pressure and / or the noise radiation emitted by the pump and / or the absorbed active power of the pump can be used.
- the detection device is designed to determine the pump speed and / or the pump pressure.
- the detection device is for detecting the noise radiation emitted by the pump, e.g. Volume or audio frequency, formed.
- the indirect determination of the foaming on the determination of an operating parameter of the pump or the associated drive unit can be structurally particularly simple accomplish. If foaming occurs in the rinsing liquid, which is supplied to circulate the pump, this is reflected in a decreasing pump pressure and at the same time in an increasing rotational speed of the pump. As a result, the operating noise of the pump, e.g. Volume or tone frequency.
- the pump speed can be determined via an arbitrarily designed speed sensor. If the speed of the pump can be controlled or regulated, then no additional speed sensor need be provided, since the speed can be sensed by the pump itself. In this way, additional costs can be avoided. Alternatively, however, there is also an immediate detection of foaming, e.g. conceivable with the aid of optical and / or chemical sensors.
- the evaluation unit can advantageously be integrated into the control unit for controlling the distributor unit, but can also be designed as an independent unit or integrated into the sensor system.
- the control unit controls the distributor unit such that the rinsing liquid is distributed to the upper basket spraying device and / or the ceiling spraying device.
- a corresponding operating method provides that, when in a lower basket operation, in which the rinsing liquid is distributed exclusively to the lower basket spray device, foam formation is detected, the distribution unit is controlled such that is changed from the lower basket operation in a Oberkorb- and / or ceiling operation ,
- the distribution unit is controlled such that is changed from the lower basket operation in a Oberkorb- and / or ceiling operation .
- a particularly effective suppression of foaming and at the same time optimum cleaning performance can be achieved by controlling the distributor unit in the low-basket mode during foaming in such a way that first for a first time in the ceiling operation and then for a second period in the upper basket operation is changed.
- FIG. 1 is a schematic representation of a dishwasher according to the invention
- FIG. 2 shows a schematic time profile of the volume flow of the rinsing liquid when using an operating method according to the invention according to a first embodiment
- FIG. 3 shows a schematic time profile of the volume flow of the rinsing liquid when using an operating method according to the invention according to a second embodiment.
- FIG. 1 shows a dishwasher with a rinsing container 1 delimiting a washing compartment.
- a not-shown items to be cleaned can be arranged in dish racks in the form of a lower basket 3 and an upper basket 5.
- three spraying devices provided in different spraying levels are arranged by way of example in the form of a lower basket spraying device 7, an upper basket spraying device 8 and a ceiling spraying device 9, via which the washware to be cleaned is supplied with washing liquid.
- the lower basket spraying device 7 and the upper basket spraying device are exemplified as spray arms and the ceiling spraying device 9 exemplified as a shower head.
- a sump 10 is only roughly attached.
- a circulation line 12 with pump 13 arranged therein is led away in the form of a circulating pump 13 'and a downstream water heater 14.
- a distributor unit 15 in the form of a water distributor 15 ' is provided, at which three supply lines 16 branch off from the circulation line 12.
- the circulating line 12 is connected to the spraying devices 7, 8, 9 via the supply lines 16.
- the water diverter 15 ' serves to distribute the rinsing liquid conveyed by the circulating pump 13' to a single or also to a group of the spraying devices 7, 8, 9.
- the dishwasher has a program control device 21 with which known program steps, such as pre-rinsing, cleaning, intermediate rinsing, rinsing and / or drying, can be carried out.
- the program control device 21 can control the respective device components via signal lines shown in dashed lines.
- the circulating pump 13 ' is assigned a drive unit 22 in the form of an electric motor 22', which drives the circulating pump 13 'via a drive shaft 23.
- the electric motor 22 ' can be designed, for example, as a so-called BLDC motor, that is, brushless DC motor.
- the electric motor 22 ' may also be associated with an unillustrated inverter or inverter, the Electric motor 22 'supplied with electrical energy.
- the inverter or inverter generates the required electrical three-phase voltage for the electric motor 22 ', ie an electrical voltage with the required frequency and required RMS value.
- the program control device 21, the electric motor 22 'of the circulation pump 13' control control, if necessary, also regulate.
- an operating parameter of the electric motor 22 ' such as e.g. the speed can be detected during pump operation.
- the operating parameter thus detected is conducted via a signal line 25 to an evaluation unit 26 and evaluated there.
- the evaluation unit 26 is integrated into the program control device 21. Alternatively, however, the evaluation unit 26 can also be realized separately or integrated into the sensor system 24.
- the operating parameters detected by the sensors 24, e.g. the speed of the electric motor 22 ' is dependent on a proportion of foam in the conveyed rinsing liquid.
- a foaming in the rinsing liquid can be detected.
- any desired operating parameter of the circulating pump 13 'or the associated electric motor 22' for detecting foaming in the rinsing liquid can be detected and evaluated, provided that the operating parameter changes as a function of the proportion of foam in the rinsing liquid.
- the sensor system 24 forms, together with the evaluation unit 26, a detection device 27 for detecting foam formation in the rinsing liquid.
- FIG. 2 shows schematically the time course of the volume flow of the rinsing liquid.
- the dishwasher is operated in lower basket operation. This results in a maximum volume flow Q1. Due to the high volume flow and the permissible air content in the lower basket operation, foaming in this operating mode can not be ruled out.
- the water switch 15 ' is controlled by the associated control unit 17, which is realized in the illustrated embodiment as part of the program control device 21, but which can also be realized separately thereto, such that the flushing liquid is distributed exclusively to the ceiling spray device 9 ,
- the volume flow abruptly drops to a minimum value Q2.
- the reduced volume flow leads to a significant reduction of the air content in the rinsing liquid and thus to avoid further foaming. Rather, the already formed foam is reduced again.
- the operation of foam acts as a settling phase with regard to foam formation, in which the foam formed can degrade again.
- the water switch 15 ' is again controlled by the control unit 17 accordingly.
- the average volume flow Q3 leads in comparison to the high volume flow Q1 during the lower basket operation even to a reduction in the proportion of air in the rinsing liquid, in which further foaming is avoided and in which already formed foam can degrade again.
- the upper basket operation still acts as a calming phase with regard to foam formation.
- FIG. 3 shows schematically the time profile of the volume flow of the rinsing liquid when using an operating method according to the invention in accordance with a second embodiment.
- the second embodiment differs from the first embodiment only in that after a renewed change to the lower basket operation at time 4, the speed of the circulating pump 13 'associated electric motor 22' compared to the previous lower basket operation in the period between TO and T2 is reduced which manifests itself in a volume flow Q1 'reduced to the maximum volume flow Q1. If necessary, this reduction in the speed can also be continued over several periods, as shown.
- the invention has been described by way of example for a dishwashing machine in which different volume flows of the washing liquid result in lower basket operation, in upper basket operation and in ceiling operation, which supports the desired suppression of foam formation. It should be expressly understood, however, that the In principle, the changed liquid paths and / or the resulting changed impact characteristics of the downwardly flowing rinsing liquid on the container bottom can bring about the desired suppression of foam formation.
