Definitions
- Dishwasher with a system for atomizing rinsing liquid and method of operating the same
- the subject matter of the present invention is a dishwashing machine with at least one washing container and a device for wetting items to be washed arranged in the washing container with washing liquid.
- the invention relates in particular to a
- Dishwasher with a system for uniform distribution of washing liquid in the washing and a method for operating the same.
- the invention further relates to a device for dishwashers for the metered delivery of washing-active substances, such as e.g. Cleaning or rinse aid.
- rinsing liquid used to increase the cleaning performance with washing-active substances, e.g. a cleaning agent is added.
- Rinsing liquid sprayed by spraying in the washing After the last rinsing process, a rinsing phase is generally carried out, in which the rinsing liquid is mixed with a rinse aid. It has been found to be advantageous for the cleaning result if the rinsing liquid added with cleaning agent is evenly distributed on the items to be washed before the actual rinsing process is carried out and can act on the soiling on the items to be washed for a certain time. In some wash programs, therefore, the items to be washed are wetted at the beginning of the wash program via the spraying with rinse liquid, which has been previously mixed with detergent.
- dishwashers with spray devices are known in which the rinsing liquid is distributed by means of rotating spray arms in the washing. Since the washing compartment in dishwashers usually has a rectangular outline, while the rotating spray arms have a circular area of action, the washing liquid is not evenly distributed in each area of the washing compartment.
- dishwashers with sprayers which have a fixed spray nozzle or spray nozzle, which on the rear wall of the Rinsing container is arranged, which is applied in the washing container Spülillonkeit with rinsing liquid.
- spraying devices are known in the prior art, which act on so-called spray floors the washware located above it with rinsing liquid.
- Auxiliaries for spraying liquids from other technical fields are already known in the prior art, such as e.g. in the cosmetics industry for the atomization of hair sprays and perfumes, in medicine for the atomization of medical agents, in chemistry for the atomization of liquid reagents, as well as in the field of home technology as a room humidifier.
- Some known atomizers operate by means of mechanical atomization in which the liquid to be atomized is removed by mechanical means, e.g. a valve is placed under pressure. As a result, the liquid to be atomized flows out into small droplets and forms a liquid mist.
- the required overpressure is achieved by a pumping operation, for example in perfume atomizers manually, or by using overpressure reservoirs, e.g. Propellant in hair sprays, generated.
- Such aids for the atomization of rinsing liquid by so-called atomizers or nebulizers are also known in their use in dishwashers.
- the atomization of the rinsing liquid added with washing-active substances generates a mist of rinsing liquid droplets with small droplet diameters, which increases the effectiveness of the rinsing liquid added with washing-active substances, since rinsing liquid droplets with small droplet diameters can penetrate better into the soiling on the items to be washed.
- the document EP 487 474 describes a dishwashing machine in which the rinsing liquid mixed with cleaning agent by means of an ultrasound generator in the rinsing container of the
- Dishwasher is atomized.
- the system disclosed in EP 487 474 has the disadvantage that, although the rinsing liquid is atomized to a fine mist, but an efficient distribution of the atomized rinsing liquid in the washing is not guaranteed.
- a further object of the present invention is to provide a dishwasher with a device, whereby the amount of washing-active substances required in the rinsing liquid for optimum cleaning effect can be regulated.
- Yet another object of the present invention is to provide a method for operating a dishwasher with a system for atomizing the rinsing liquid, which is characterized by high cleaning performance.
- a dishwasher is proposed with at least one rinsing container for receiving items to be cleaned, which is supplied with rinsing liquid during the rinsing operation, and an atomizing apparatus for atomizing rinsing liquid, in particular for atomizing with washing-active substances
- Substances of offset rinsing liquid wherein the atomizing device comprises an electrically operated ultrasonic generator and a blower through which the atomized rinsing liquid is conveyed into the washing compartment.
- the present invention thus provides a dishwashing machine with a system for atomizing the rinsing liquid which, by the use of an electrically operated ultrasound generator or atomizer, enables a small and inexpensive system for effective atomization and distribution of rinsing liquid as well as washing-active substances in the rinsing container of the dishwasher.
- the atomization of the rinsing liquid in the smallest possible droplet diameter has the consequence that the rinsing liquid and the washing-active substances dissolved therein to the Soiling of the dishes can attack more effectively, where it can easily penetrate into the cracks and pores of stains.
- the uniform distribution of the atomized, with washing-active substances added rinsing liquid in the washing by the blower ensures a uniform effect of the atomized rinsing liquid and the washing-active substances dissolved therein in the soiling of the dishes.
- the efficiency of the washing-active substances is improved and, on the other hand, the cleaning performance of the dishwasher is increased overall, resulting in a reduction of the required amount of washing-active substances and thus a lower environmental impact.
- the above-described properties of the atomizer considerably improve the droplet distribution, the precision of the volume to be atomized and thus the dosage of the washing-active substances in the rinsing liquid.
- the ultrasound transducer eliminates the use of a nozzle, thus avoiding the risk of blockage or jamming of spray nozzles in the atomizer. As a result, the system is largely maintenance-free and durable and suitable for multiple use by way of recycling. Due to the low power requirement of the piezoelectric actuator of the ultrasonic generator energy consumption is further reduced.
- a piezoelectric atomizer is used as the electrically powered nebulizer.
- Piezoelectric atomizers are based on piezoelectric substrates that are electrically excited to vibrate, whereby a liquid located on the surface of the piezoelectric substrate is atomized by the resulting capillary waves.

- the geometric dimensions of the membrane, the liquid delivery, and the frequency of oscillation used as atomization parameters are accordingly adjusted to produce the desired droplet size.
- the cracks and pores or capillaries which usually occur when stains on items to be washed, are approximately between 1 and 6 microns in size.
- the rinse liquid By atomizing the rinse liquid into droplets having a diameter of between 1 and 3 microns, these can easily penetrate into the capillaries of the soil, thereby accelerating the dissolution and swelling of the soil.
- the cleaning agent in particular the surfactants, causes a reduction of the surface tension, typically by a factor of 2, and thus leads to the formation of smaller droplets. This effect in turn favors the penetration of the atomized rinsing liquid into the pores and cracks of the stains.
- the soiling with rinsing liquid and the washing-active substances dissolved therein are wetted with the mist droplets, and the washing-active substances penetrate directly into the capillaries of the soil.
- the atomizer device comprises a misting container, in which the rinsing liquid or the fresh water after atomization through the atomizer device and transported from the blower at least partially into the washing compartment of the dishwasher.
- the rinsing liquid mixed with the washing-active substances can first be homogeneously atomized before it is introduced into the rinsing container via the blower.
- the rinsing liquid thus mixed in a pre-atomized state and homogeneously mixed with the washing-active substances added can, if required, act on the dishes in the washing compartment in a rapid and effective manner.

- the atomizing device is arranged in the floor, ceiling and / or wall region of the washing container and has at least one opening for the passage of the atomized washing liquid on a side directed towards the interior of the washing container. Such an arrangement allows both a space-saving placement of the atomizer and short ways, for example, from the misting container on the blower to the washing.
- the atomizer device is preferably connected to a fresh water line, via which the atomizer fresh water can be supplied.
- the atomizer device has a detergent addition chamber into which detergent substances, in particular cleaning agents and / or rinse aids, can be introduced in order to come into contact with the rinsing liquid or with the fresh water.
- the washing-active substances are suitably mixed with rinsing liquid and / or fresh water, wherein the mixing or dissolution of the washing-active substances in the rinsing liquid can be assisted by the operation of the ultrasound generator.
- the rinsing liquid or the fresh water can also be mixed with washing-active substances before it is fed to the atomizing device.
- a metering device with at least one reservoir for washing-active substances, which can deliver detergent and / or rinse aid, in one or more portions of any amount to the rinsing liquid.
- the introduction of the washing-active substances to the rinsing liquid from the dosing device or the reservoir for the detergent-active substance preferably takes place in the detergent-adding chamber of the atomizer device. As a result, a precise dosage of the detergent substance can be made as needed.
- a method for operating a dishwasher of the type described above comprising the following steps: feeding rinsing liquid and / or fresh water into the atomizing device, Feeding and mixing of washing-active substances, in particular cleaning agents and / or rinse aids into the rinsing liquid or into the fresh water,
- Atomizing or misting the rinsing liquid added with the washing-active substances or the fresh water added with the washing-active substances by means of an electrically operated ultrasound generator and
- the rinsing liquid is first mixed with washing-active substances, then atomized by the ultrasound generator and then introduced and distributed via the blower into the rinsing container of the dishwasher. There, the washing active substances dissolved in the rinsing liquid as misted steam and small
- the feeding or mixing of the washing-active substances in particular the feeding or mixing of cleaning agents in the form of so-called tabs or powder form, into the rinsing liquid is assisted by the operation of the ultrasound generator.
- the capillary waves generated by the ultrasound generator promote and accelerate a complete dissolution of the cleaning agent in the rinsing liquid.
- the introduction of the atomized, with washing-active substances, in particular detergent mixed with rinsing liquid in the washing before a first rinsing process can act on the dishes.
- the stains are voranfug on items to be washed and can be easily and quickly eliminated in a subsequent flushing.
- the introduction of the atomized, with washing-active substances, in particular with rinse aid added rinse liquid in the washing before a rinse occurs.
- the rinse aid before the rinse cycle in fine droplets can be evenly distributed in the desired dosage on the items to be washed in the washing, thereby reducing the amount of rinse water required.
- the introduction of the atomized rinsing liquid mixed with rinse aid into the rinsing container takes place before a drying process is carried out.
- the droplets of the rinsing liquid mixed with rinse aid can act as condensation nuclei, so that the humidity in the rinsing container drops faster during the drying process and the overall drying process is shortened.
- surfactants are generally used as detergent substances, which have the property of lowering the surface tension of liquids and thus increasing the cleaning effect.
- the detergent activity of surfactants is highly dependent on their type and concentration in the detergent solution.
- the amount of washing-active substances, the the rinsing liquid or the fresh water is supplied before the atomization by the atomizer in the washing of the dishwasher, controllable.

- the rinse aid-enriched droplets of the mist generated By applying the rinse aid-enriched droplets of the mist generated to the rinse aid, a relaxation of the water on the dishes is achieved, which accelerates the rinse process. This makes it possible to carry out the rinsing process instead of a liquor filling of currently approximately 2 liters of water only with a smaller amount of water.
- FIG. 3 shows a cross section through the atomizing device in the embodiment of the present invention shown in FIG. 1 in the operating state during a drying process.
- fresh water is atomized without additives in the detergent addition chamber 3 by the ultrasonic generator 2 by means of ultrasound and blown through the fan 12 into the interior of the washing container.
- the droplets thus atomized are now condensation nuclei for the steam present in the interior of the washing container and thus cause an accelerated drying of the dishes. If the mist is additionally blown to a wall of the dishwasher interior, this leads to a cooling of the Spül employmenterwand and thus to an accelerated condensation of water vapor on this wall. In this way, the drying process is shortened, saving both time and energy.
