Description

The present invention relates to a laundry care device with a filter element.

Certain device variants of conventional laundry care devices have fluid-carrying lines through which fluids for maintaining the laundry, e.g. Washing liquid for cleaning the laundry, are pumped. Since the fluids come into contact with the laundry during the laundry care process, contaminants such as e.g. Lint or dust, taken up in the fluid and carried by the fluid through the fluid-carrying lines. In order to filter such contaminants from the fluid, certain device variants of conventional laundry care devices have filter elements through which the fluid flows.

In order to support the laundry care process, a large number of active ingredients are added to the fluid for laundry care in conventional laundry care devices. Corresponding active ingredients include, for example, fragrances, bleaches and / or water softeners. However, corresponding active ingredients often have to be added to the laundry care device, such as be introduced into the induction bowl, or fed directly to the laundry in the laundry drum.

In the WO 2013/068300 A1 discloses a washing machine with a filtration device for filtering washing liquid.

In the WO 2005/115922 A1 discloses a water filtration system that includes a water filter and an additive delivery system.

It is the object of the present invention to provide a laundry care device with an active ingredient-dispensing filter element.

This object is achieved by the subject with the features according to the independent claim. Advantageous embodiments are the subject of the dependent claims, the description and the drawings.

According to one aspect, the object of the invention is achieved by a laundry care device, with a tub for receiving washing liquid, the tub having an outlet opening and an inlet element, a pump for pumping the washing liquid, a pump-around line, which connects the outlet opening with the inlet element in terms of fluid technology, wherein the pump is designed to pump washing liquid from the tub through the drain opening into the pumping line and to feed the washing liquid from the pumping line and through the inlet element again to the tub, the laundry care device having a filter element which is fluidically connected to the pumping line and is formed of impurities from the filter washing liquid pumped through the pumping line, wherein the filter element has an active ingredient, and wherein the filter element is designed to transfer the active ingredient to the water pumped through the pumping line dispense liquid.

This achieves the technical advantage that two functionalities can be combined in the filter element by the filter element that is fluidically connected to the pump-around line. On the one hand, the filter element can ensure effective filtering of impurities from the washing liquid pumped through the pumping line. On the other hand, the filter element has the function of an active substance reservoir, whereby the delivery of the active substance to the washing liquid pumped through the pumping line can be ensured during use of the filter element.

In a conventional laundry care process, the laundry is wetted with washing liquid in a laundry drum and maintained by rotating the laundry drum. This can result in abrasion of plastic particles, especially microplastic particles with a small diameter, in particular in laundry items made of synthetic fibers, the plastic particles being carried along by the washing liquid and being returned to the laundry during a pumping-over process or during a pumping-down process of the environment be fed.

The filter element fluidically connected to the pump line according to the present disclosure is advantageously designed to filter out impurities, in particular plastic particles, from the washing liquid pumped through the pump line.

In particular, the filter element is arranged in the pump-around line.

During a conventional laundry care process, a variety of active ingredients, e.g. Fabric softener, bleach, descaling agent, etc. added to improve the result of the laundry care process. In conventional laundry care devices, such active ingredients are either placed in a washing-up bowl of the laundry care device or, if appropriate, have to be fed directly into the laundry taken up in the laundry drum, which is often associated with increased effort for the user of the laundry care device.

The filter element fluidically connected to the pump line according to the present disclosure has an active ingredient and is designed to deliver the active ingredient directly to the washing liquid pumped through the pump line. A manual addition of the active ingredient by the user, which is necessary for each laundry care operation, is thus dispensed with, since a sufficient concentration of the active ingredient is present in the pumped-over washing liquid by dispensing the active ingredient through the filter element. Thus, the active ingredient contained in the pumped-over washing liquid can be effectively supplied to the laundry during the pumping-over process.

Since the filter element inevitably clogs up due to the accumulated impurities during operation of the laundry care device, the filter element only has to be replaced after longer service intervals, so that in this case either a new filter element with active ingredient can be used or the impurities are removed from the filter element and the active ingredient can be reintroduced into the filter element.

In one embodiment, the filter element containing the active ingredient can also be replaced after each laundry care process, so that a disposable filter element that is easy to change by the user can be provided.

The active ingredient comprises in particular a single active ingredient or a plurality of active ingredients. The at least one active ingredient comprises in particular a water-soluble active ingredient or a water-soluble active ingredient mixture.

In particular, a cover of the laundry care device, behind which the filter element and / or the further filter element is arranged, can be designed at least in sections to be light-transparent in order to enable the user to see the filter element. Either the dye can be rinsed out of the filter element by the washing liquid flowing around the filter element, as a result of which the user is informed of a necessary change of the filter element by decolorization of the filter element. Alternatively, a dye present in the washing liquid can be absorbed by the filter element due to the washing liquid flowing around the filter element, as a result of which in this case the user is shown a necessary change of the filter element by coloring the filter element. If the dye is part of the active ingredient or can be incorporated into the active ingredient, a necessary change is indicated by a change in the color of the active ingredient.
