It is provided a circuit for media management, to which the treatment tank and the mist source are connected.

In EP 2 703 540 A2 a tumble dryer or a washing machine is described with a total care function for example bedding. The control method may include a sterilization program, a deodorizer program, a pest removal program, a dust removal program, or a refresh program, and may independently perform any overall care function.

It is the object underlying the invention to provide a laundry care device in which an effective odor reduction of laundry is effected and an additive is effectively delivered to the laundry.

This object is achieved by articles having the features according to the independent claim. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims.

According to one aspect of the invention, the object is achieved by a laundry care apparatus for maintaining laundry, wherein the laundry care appliance comprises a laundry drum for receiving laundry, a mist generator for generating a water mist, and a deodorizer with an ozone generating element for generating ozone, wherein the mist generator is configured to generate a quantity of water mist in a first period of time and to supply the laundry drum, wherein the ozone generating element is adapted to generate a quantity of ozone in a second period subsequent to the first period and to supply the laundry drum to an odor reduction of the laundry and wherein the deodorizing device further comprises an additive dispensing element, which is designed, in a third period subsequent to the second time period, an amount of an additive through the mist-generating device to the Dispensing laundry drum to supply the additive to the laundry.

Thereby, the technical advantage is achieved that the successive addition of the amount of ozone and the amount of the additive in the laundry drum effective odor reduction of the laundry to be cleaned in the laundry care device is achieved, and the additive can be delivered effectively to the laundry.

In addition, by using ozone, a reduction in the germ load of the laundry can be achieved, whereby the temperature during a laundry care process can be reduced, since a further reduction of the germ load of the laundry by an elevated temperature is no longer necessarily required. As a result, the energy consumption of the laundry care process can be reduced.

Due to a heavy contamination of laundry, such. B. by contamination of the laundry with body sweat, the laundry may contain unpleasant smelling odors. The treatment of the laundry to be treated with ozone has proved to be advantageous in the deactivation of odor-active substances. Ozone is a strong oxidizing agent that can oxidize and deactivate odors, thereby achieving effective odor reduction in the laundry. Through the oxidation of unpleasant-smelling odors, the odorants are deactivated and can no longer be perceived by humans. As a result, the odors lose their unpleasant-smelling properties. However, the oxidation effect of ozone is not limited to unpleasant-smelling substances. Ozone also oxidizes and deactivates other positive-acting additives that are added by the user of the laundry care device. Additives, such as. B. fragrances can be added during a laundry care process of the laundry to a positive effect for the user, such. B. to achieve a positive aroma of the laundry.

For this reason, sequential addition of ozone and additives has been found to be advantageous. In a first period, a mist is generated by a mist generator and supplied to the laundry drum. As a result, there is a wetting of laundry located in the laundry drum. In a second period following the first period, a quantity of ozone is generated by the ozone generating element of the deodorizing device and supplied to the laundry drum. The supplied ozone can oxidize and thus deactivate odors in the laundry, thereby causing an odor reduction of the laundry. After the second period has ended, it may be advantageous to wait for a further period of time in order to achieve that ozone remaining in the laundry drum decomposes due to its instability at room temperature. The further period of time may depend on the half-life of ozone and may, in particular, be in the range of 5 minutes to 25 minutes.

In a third period subsequent to the second period, the amount of additive is released by the additive discharge element through the mist generator to the laundry drum. The generated amount of ozone may optionally be supplied to the laundry drum by a siphon, thereby allowing a continuous filling of the laundry drum with a mixture of water mist and the additive. As a result, an effective distribution of the additive is achieved with the water mist generated by the mist generator on the laundry. As a result, the odor-reduced laundry can be mixed with the additive without the additive being oxidized by any ozone remaining in the laundry drum and thus deactivated.

An additive may be any type of substance that is added by the user of the laundry care device in addition to the main care product. In a washing process, for example, the washing agent added by the user, as the main care product, has the effect of achieving a cleansing of the laundry to be nourished. The additive is added by the user in addition to the detergent during the laundry process to achieve another effect. The additive may comprise various flavorings or fragrances, so that the laundry after the laundry care process has a pleasant smell for the user of the laundry care appliance. The perfume may be a liquid or a gaseous perfume, such as. B. lavender flavor or other flavorings. The additive may contain other substances, such. As an impregnating agent, to achieve after the laundry treatment process, an impregnation of laundry items. The additive may comprise a bleaching, disinfecting, coloring, or coating agent, or any other type of agent added in addition to the main care agent during the laundry care process.

A corresponding treatment of the laundry to be cared for with ozone and with an additive can be carried out before, during or after a conventional laundry care operation with moist or dry laundry in the laundry drum.

Thus, an effective odor reduction of the laundry after the laundry care process can be achieved, and after the odor reduction, an additive to the laundry are supplied without the additive is deactivated by remaining in the laundry drum ozone.

Under a laundry care device is understood a device which is used for laundry care, such. As a washing machine, or a tumble dryer. In particular, such a laundry care appliance is understood as a household laundry care appliance. So a laundry care device, which is used in the context of household management, and is treated with the laundry in normal household quantities.

In an advantageous embodiment of the laundry care device, the ozone generating element is formed, the amount of ozone generated by the mist generator of the To supply laundry drum as an ozone-containing water mist.

Thereby, the technical advantage is achieved that an ozone-containing water mist is generated by the introduction of ozone in the water mist generated by the mist generator, which can be absorbed by the laundry, thereby the odor of the laundry can be effectively reduced because ozone as Ozone-water mixture or as an ozone-water mist mixture can be effectively absorbed by the laundry. Thus, unpleasant-smelling odors not only in the laundry drum itself, but also directly in the laundry, z. B. directly on the laundry fibers, be disabled. Thus, an effective odor reduction of the laundry is effected in the laundry drum.

In a further advantageous embodiment of the laundry care device, the ozone generating element is designed to supply the amount of ozone by an ozone line of the laundry drum as an ozone-air mixture.

As a result, the technical advantage is achieved that an odor reduction of the laundry is achieved even with dry laundry by the introduction of ozone in the laundry drum as ozone-air mixture, which can be dispensed with the implementation of an unnecessary washing with washing liquor. If the laundry has only unpleasant odors, but does not require intensive cleaning, then the laundry to be cared for can be added to the laundry drum in a dry state. The mist generator is configured to generate a quantity of water mist which is supplied to the laundry. The ozone-air mixture can be supplied as gas through the ozone line of the laundry drum. Thus, an effective odor reduction of the laundry in the laundry drum is effected without having to perform a laundry process with a washing process.

In a further advantageous embodiment of the laundry care device, the ozone generating element is designed to generate the amount of ozone under the action of UV light or by dielectrophoresis.

As a result, the technical advantage is achieved that the generation of a constant amount of ozone over a longer period can be ensured by the generation of ozone by dielectrophoresis or by UV light. In a dielectrophoresis-based ozone generating element, ozone is generated from molecular oxygen as part of a silent electrical discharge by two electrodes of opposite charge. In an advantageous embodiment, ozone is produced by dielectrophoresis. By electrophoresis ozone can be produced with little effort and with an ozone concentration of between 3% by volume and 6% by volume. In the ozone generating element in which ozone is generated under the action of ultraviolet light, ozone is generated from molecular oxygen by the action of ultraviolet light. In UV-based ozone generating elements, ozone can be produced at a concentration of between 0.5% by volume and 1% by volume. Thus, by means of an ultraviolet light or dielectrophoresis based ozone generating element, the amount of ozone can be generated to effect effective odor reduction in the laundry to be nourished.

In a further advantageous embodiment of the laundry care device, the laundry care device comprises an ozone removal device, wherein the ozone removal device is designed to remove a further amount of ozone in the laundry care device.

Thereby, the technical advantage is achieved that is prevented by the ozone removal device that remains after the odor reduction of the laundry excess ozone in the laundry care device, which can deactivate a subsequently added additive. The ozone removal device may comprise an activated carbon filter, by which the further amount of ozone in the laundry care device can be deactivated, for. B. by conversion of ozone into carbon dioxide. Alternatively, excess ozone can also be removed from the laundry care appliance by the ozone removal device. The ozone removal device, z. As the activated carbon filter can be controlled so that the further amount of ozone, or the excess ozone, after completion of the ozone treatment of the laundry is removed from the laundry care device. This is particularly advantageous when the amount of ozone generated by the ozone generating element exceeds the amount of ozone really needed for the laundry care process. By using the ozone removing device, the additional amount of excess ozone can be removed from the laundry care device. Thereby, an effective odor reduction of the laundry in the laundry drum can be achieved without causing a deactivation of the subsequently added additive.

In a further advantageous embodiment of the laundry care device, the ozone removal device is designed to remove the further amount of ozone after the second period has ended in the laundry care device.

Thereby, the technical advantage is achieved that is achieved by a timely controlled removal of excess ozone by the ozone removal device, a dosage of ozone concentration in the laundry care device with respect to the really required amount of ozone in the laundry care device. This ensures that in the second period, an amount of ozone is present in the laundry drum to effect an effective odor reduction of the laundry. On the other hand, after an effective odor reduction of the laundry, so after completion of the second period, the ozone concentration can be greatly reduced, or the ozone can be completely removed from the laundry drum. This ensures that the added in the third period additive is not deactivated by remaining ozone, or that there is no damage to the laundry fibers or the user by ozone. An ozone eliminator may include an activated carbon filter that converts ozone to carbon dioxide. An ozone eliminator may comprise a suitable catalyst, e.g. B. made of copper or manganese to eliminate ozone. An ozone removing device may comprise a heating element through which the ozone-enriched air to a high temperature, such. B. 300 ° C, is heated, and thereby the degradation of ozone is accelerated. Thus, by the targeted removal of ozone after the second period has ended, an effective odor reduction of the laundry is achieved, and a subsequent addition of the additive to the laundry is made possible.

In a further advantageous embodiment of the laundry care appliance, the laundry care appliance comprises a controller and a valve, wherein the controller is designed to determine the amount of the additive, and wherein the controller is designed to control the valve such that the determined amount of the additive through the Mist generation device is delivered to the laundry drum.

Thereby, the technical advantage is achieved that is achieved by the controller and the valve, that the additive is delivered in the advantageous amount and at an advantageous time to the laundry. It has proved to be advantageous that the additive is added only after the end of the second period in order to prevent the additive from being deactivated by ozone remaining in the laundry drum. Thus, the valve can be controlled by the controller such that the additive is added only after the second period has ended. In addition, the controller may be configured to determine the amount of additive required. The determination of the amount of additive required may depend on the amount of laundry or type of laundry or the laundry care program selected by the user. Thus, an advantageous dosage of the amount of additive is achieved by the controller and by the valve. As a result, after the odor reduction of the laundry, the required amount of the additive can be released to the laundry.

In a further advantageous embodiment of the laundry care appliance, the valve is designed as a three-way valve, wherein the three-way valve is connected to the additive delivery element through a first section of a supply line, with the mist production device through a second section of the supply line, and with a water supply device through a third section of the supply line wherein the three-way valve is configured, in a first valve setting, the amount of the additive through the first portion and the second portion of the supply line of the mist generator and in a second valve setting a quantity of water from the water supply means through the third portion and the second portion of the supply Supply mist generating device.

This achieves the technical advantage that either the amount of water from the water supply device or the amount of additive from the additive discharge element can be supplied by the three-way valve depending on the period of the laundry care process of the laundry by the mist generator. During the first period, the mist generator needs water to produce a mist of water. The required amount of water is provided by the water supply device and directed to the mist production device through the three-way valve. The three-way valve ensures that only water is supplied to the mist generator in the first period and no additive is discharged from the additive discharge member to the mist generator in the first period. This prevents the additive from being deactivated by ozone in the second period following the first period. After completion of the second period and the odor reduction of the laundry caused by the ozone, the three-way valve discharges the amount of additive from the additive discharge member to the laundry through the mist generator in a third period subsequent to the second period. Thus, by the regulation of the addition of water and additive in the respective periods by the three-way valve effective odor reduction of the laundry and an adjoining effective addition of additive to the laundry causes.

In a further advantageous embodiment of the laundry care appliance, the laundry care appliance comprises a further additive dispensing element, which is designed to deliver a quantity of a further additive through an air channel to the laundry drum.

Thereby, the technical advantage is achieved that can be supplied by the use of the further additive delivery element of the further additive of the laundry in the laundry drum. For example, the first additive may be a fragrance to provide the laundry with a pleasant fragrance, while the other additive, for. As an impregnating agent comprises, to effectively impregnate the laundry items. The delivery of the additional additive to the laundry drum through the air duct has the advantage that the additional additive can be dispensed directly to the laundry drum, and must not be passed through the mist generator. This type of dispensing is advantageous when the half-life of the further additive is low, and therefore must be quickly supplied to the laundry, or if the further additive is not suitable to be delivered as an additive-containing water mist to the laundry drum. Thus, by the use of the further additive delivery element and the supply of the further additive through the air duct, an effective delivery of all the required additives to the laundry can be achieved.

In a further advantageous embodiment of the laundry care appliance, the further additive dispensing element comprises an exchangeable cartridge.

As a result, the technical advantage is achieved that is achieved by using a replaceable cartridge as another additive delivery that the user of the laundry care device can exchange the other additive used flexibly depending on the laundry care process. For strongly smelling laundry another cartridge with a different additive can be used, as z. B. with weak-smelling laundry items. The cartridge may be configured to be replaced after one or more laundry processes, and may be reused after replacement. The cartridge can be designed to store the additional additive used in a stable form over a longer period of time and to release the further additive when dispensed in an active form, so that the further additive achieves a beneficial effect in the laundry to be cared for. By using a replaceable cartridge, the effective delivery of all required additives to the laundry can be ensured.

In a further advantageous embodiment of the laundry care device, the laundry care device comprises a load detection device for detecting a laundry or laundry type in the laundry drum and a controller, wherein the controller is adapted to determine a time interval of ozone generation depending on the detected laundry load or laundry type, and wherein the ozone generating element is designed to generate the amount of ozone in the specific time interval.

Thereby, the technical advantage is achieved that by detecting the amount of laundry or laundry of the laundry in the laundry drum by the load detecting means, the advantageous amount of ozone can be determined by the controller and generated by the ozone generating element to effect an effective odor reduction of the laundry to be cleaned.

The type of laundry to be cleaned influences the required amount of ozone. In a type of laundry that has a large surface, such. As towels, a large amount of ozone is needed to effect an effective odor reduction of the laundry. As another example, used here are pieces of laundry with cotton fibers, which have a large surface area and therefore can bind a large amount of ozone. Accordingly, when using laundry with cotton fibers, a larger amount of ozone must be supplied to the laundry drum than is the case with conventional laundry fibers. In a type of laundry, which can absorb a small amount of ozone, such. As polyester fibers, a small amount of ozone is needed to reduce odors. Thus, by detecting the amount of laundry or type of laundry, accurate determination and generation of the required amount of ozone is achieved, thereby effecting effective odor reduction of the laundry in the laundry drum.

In a further advantageous embodiment of the laundry care appliance, the additive dispensing element is designed to determine the amount of at least one additive as a function of the detected laundry load or type of laundry, wherein the additive dispensing element is designed to deliver the determined quantity of at least one additive to the laundry drum.

Thereby, the technical advantage is achieved that by the detection of the amount of laundry or the type of laundry, the amount of additive dispensed by the additive delivery element can be adapted to the amount of additive really required. The amount of additive really needed depends on the amount of laundry or Type of laundry. A larger amount of laundry correlates with a larger amount of the required additive. Also, depending on the type of laundry, a larger or smaller amount of the additive is needed. Thus, by detecting the amount of laundry or type of laundry by the load detecting means, the really required amount of the additive can be delivered to the laundry.

In a further advantageous embodiment of the laundry care device, the laundry care device comprises a level sensor, a flow sensor and a controller, wherein the level sensor is adapted to detect a level of water or wash liquor in the tub, wherein the flow sensor is formed, a flow rate of water or wash liquor a water or wash liquor feed line in a further time interval, wherein the controller is adapted to determine the amount of ozone in dependence on the detected level and in dependence on the detected flow rate, and wherein the ozone generating element is formed, the predetermined amount of ozone depending on the detected level and depending on the detected flow rate.

Thereby, the technical advantage is achieved that the detected by the level sensor amount of water or wash liquor in the tub correlated with the laundry load or the type of laundry. With a full load of the laundry drum with laundry a larger amount of wash liquor is absorbed by the laundry, as if only a small amount of laundry in the laundry drum is present. Likewise, the level of water in the tub is dependent on the type of laundry laundry. If an absorbent laundry type is present in the laundry drum, then a larger amount of water is absorbed through the laundry than when a low-speed laundry type is used. By a flow sensor in a water or washing liquor supply line, the flow velocity can be detected in a time interval and thereby closed in the time interval to the amount of water supplied to the tub. By using the level sensor and the flow sensor, the amount of ozone required for the cleaning process can thus be generated by the ozone generating element and fed to the laundry drum, whereby an effective odor reduction of the laundry is achieved.

In a further advantageous embodiment of the laundry care appliance, the laundry care appliance comprises an ozone sensor and a controller, wherein the ozone sensor is designed to detect an ozone concentration value in the laundry drum, wherein the controller is designed to determine the amount of ozone in dependence on the detected ozone concentration value, and wherein the ozone generating element is configured to generate the predetermined amount of ozone depending on the detected ozone concentration.

Thereby, the technical advantage is achieved that by using the controller and the ozone sensor, the ozone concentration value in the laundry drum can be determined and thereby the generation and addition of a favorable amount of ozone to the laundry in the laundry drum can be ensured by the ozone discharge member. The ozone sensor enables the direct transfer of the detected ozone concentration value in the laundry drum to the ozone generating element. The ozone generating element can thus respond without delay and automatically to a too low or too high ozone concentration value in the laundry drum, and increase or reduce the generation of ozone. By setting the advantageous ozone concentration value in the laundry drum, an effective odor reduction of laundry in the laundry drum can be achieved.

In a further advantageous embodiment of the laundry care appliance, the laundry care appliance comprises an additive sensor and a controller, wherein the additive sensor is configured to detect an additive concentration value in the laundry drum, wherein the controller is configured to determine the amount of additive as a function of the detected additive concentration value, and wherein the additive delivery member is adapted to deliver the determined amount of additive to the laundry drum depending on the detected additive concentration.

Thereby, the technical advantage is achieved that can be detected by the use of the additive sensor, the additive concentration value in the laundry drum, and thereby the amount of additive can be determined and delivered to the laundry drum to achieve an advantageous distribution of the additive on the laundry. The additive sensor allows for the direct transfer of the detected additive concentration value to the additive delivery element. The additive delivery element can thus react without delay and automatically to a too low or too high additive concentration value in the laundry drum, and increase or reduce the delivery rate of the additive. By adjusting the beneficial additive concentration value in the laundry drum can an effective addition of the additive to the laundry in the laundry drum can be achieved.
