Description
Technical Field
The invention relates to a laundry care appliance having a material container.
Background
In conventional laundry care appliances, chemically active bleaching agents (in particular chemical bleaching agents) are added in order to treat certain contaminants of the laundry to be treated. For this purpose, for example, a bleach-containing laundry care substance (in particular a bleach-containing all-purpose powder detergent) is manually supplied by the user of the laundry care appliance into the rinsing-in housing of the laundry care appliance.
DE 102011083572 a1 discloses a water-conducting household appliance having a container for receiving items to be cleaned, wherein the container comprises an inner surface which contains a catalytically acting substance.
DE 102013205302 a1 discloses a water-conducting household appliance which contains at least one catalytically active substance in the surface.
Disclosure of Invention
The object of the invention is, inter alia, to provide a laundry care appliance which enables an automatic addition of chemical bleaching agent.
According to one aspect of the invention, this object is achieved by a laundry care appliance having: a lye container for receiving the wash liquor; a washing drum arranged in the lye container for receiving the laundry; and a substance container for receiving a polyoxometalate catalyst (polyoxometalate-katalyzer), wherein the substance container is fluidically connected to the supply line for supplying washing liquid into the substance container, wherein the substance container is fluidically connected to the discharge line for discharging washing liquid onto the lye container, wherein the polyoxometalate catalyst is designed to: producing hydrogen peroxide by chemical reaction with the washing liquid to obtain a washing liquid containing hydrogen peroxide, and wherein the delivery line has a valve configured to: in the first position, the lye container is fluidically separated from the substance container, and in the second position, the substance container is fluidically connected to the lye container for supplying the washing liquor containing hydrogen peroxide to the lye container and for enabling bleaching of the laundry in the washing drum.
This achieves the technical advantage that: by using a polyoxometalate catalyst, a washing liquid containing hydrogen peroxide can be produced in the substance container, which washing liquid can be supplied to the lye container in a valve-controlled manner. This ensures an effective dosage of the bleaching action of the washing liquor containing hydrogen peroxide on the laundry.
In conventional laundry care appliances, a chemical bleaching dye, for example a chlorine bleach, is usually provided manually by the user of the laundry care appliance into the wash-in housing in order to achieve a bleaching action of the laundry during the laundry care process. Thus, in the event that the chemical bleaching agent is improperly added by the user to the flush-in housing, an unpleasant and potentially health-damaging odor may result.
The polyoxometalate catalyst received in the substance container according to the invention catalyzes a chemical reaction for the production of hydrogen peroxide.
Here, the polyoxometalate catalyst oxidizes molecular oxygen (molekularen Sauerstoff) to the superoxide anion (Hyperoxidanien). The generated superoxide anion can chemically react with water to produce hydrogen peroxide. The hydrogen peroxide produced can be used as a bleaching agent for bleaching laundry. Polyoxometallate catalysts are inorganic metal-oxygen clusters (metal-Sauerstoff-Cluster) which generally comprise polyatomic anions which are built up in particular from transition metal oxyanions, in particular tungstates, molybdates, vanadates, niobates and/or tantalates, and are bridged by oxygen atoms. Polyoxometallate catalysts including tungstates may include [ SiV3W9O40]7-The anion can alternatively be titanium modified (Titan-modifizer).
The polyoxometallate acts as a catalyst and is not consumed in the scope of the catalytic cycle (Katalyse-zyklus), so that hydrogen peroxide can be constantly produced. Thus, there is a constant availability of the effective bleaching action of the laundry care appliance. Thus, the user of the laundry care appliance does not have to purchase bleach again, or the manual refilling of bleach into the rinsing-in housing by the user can be dispensed with. Furthermore, in the case of polyoxometalate catalysts, no by-products harmful to the environment or unpleasant odours are produced, which occur, for example, in the case of chlorine bleaches. Furthermore, the constant availability of such a washing liquid containing hydrogen peroxide can be utilized in order to keep the laundry care appliance free of microorganisms and free of biofilms.
By a laundry care appliance is understood an appliance for laundry care (for example a washing machine or a laundry dryer). Such laundry care appliances are understood to be, in particular, household laundry care appliances.

The laundry care appliance 100 comprises a wash-in housing 101, into which a detergent or other liquid substance can be injected. The laundry care appliance 100 comprises a door 103 for loading the laundry care appliance 100 with laundry.
Fig. 2 shows a schematic view of a substance container arranged in a circulation pumping system of a laundry care appliance. The laundry care appliance 100 comprises a lye container 105 for receiving washing liquid and a washing drum 107 arranged in the lye container 105 for receiving the laundry. The laundry care appliance 100 comprises an immersion housing 101, the immersion housing 101 being fluidically connected to a water supply 109 of the laundry care appliance 100 for supplying fresh water from the water supply 109 to the immersion housing 101. The washing liquid produced by mixing the laundry care substance located in the rinsing housing 101 with water is supplied from the rinsing housing 101 to the lye container 105 via a housing line 111 which is fluidically connected to the lye container 105.
Furthermore, the lye container 105 is fluidically connected to the discharge line 113 of the laundry care appliance 100. The discharge line 113 is connected to a lye pump 115, the lye pump 115 being configured for: the washing liquid is pumped out of the laundry care appliance 100 through the discharge line 113.
Furthermore, the laundry care appliance 100 has a substance container 117, which substance container 117 is fluidically connected to a supply line 119 for supplying washing liquid into the substance container 117, wherein the supply line 119 is also fluidically connected to the lye container 105. Furthermore, the substance container 117 is fluidically connected to the lye container 105 via a discharge line 121 for discharging the washing liquid from the substance container 117.
The discharge line 121 has a valve 123, the valve 123 being configured to: in the first position, the lye container 105 is fluidically separated from the substance container 117, and in the second position, the substance container 117 is fluidically connected to the lye container 105. Thus, by the position of the valve 123 it is possible to control: whether washing liquid is supplied from the substance container 117 to the lye container 105.
The substance container 117 is part of a circulation pumping system 125 of the laundry care appliance 100, wherein the circulation pumping system 125 has a pump 127. The pump 127 is configured to: the washing liquid is pumped out of the lye container 105 through the supply line 119 and the pumped-out washing liquid is resupplied to the lye container 105 through the substance container 117 and through the lead-out line 121.
In the substance container 117, a polyoxometalate catalyst 129 is received, which polyoxometalate catalyst 129 comprises, in particular, polyoxometalate-coated particles or is, in particular, connected in a material-locking manner to a container wall 131 of the substance container 117.
The polyoxometalate catalyst 129 is an oxidation catalyst (oxidationkatalyzer) that oxidizes molecular oxygen to a superoxide anion. The generated superoxide anion can chemically react with water to produce hydrogen peroxide. The hydrogen peroxide produced here is an oxidizing agent which can be used as a bleaching agent for bleaching laundry. Polyoxometalate catalysts are inorganic metal-oxygen clusters which generally comprise polyatomic anions which are built up in particular from transition metal oxyanions (in particular tungstates, molybdates, vanadates, niobates and/or tantalates) and are bridged by oxygen atoms. Polyoxometallate catalysts 129 including tungstate may include, inter alia, [ SiV3W9O40]7-The anion may alternatively be titanium modified.
When the washing liquid is supplied to the substance container 117 through the supply line 119, the polyoxometallate catalyst 129 received in the substance container 117 reacts with the water of the washing liquid, wherein hydrogen peroxide is produced, and the washing liquid containing hydrogen peroxide is obtained. From the substance container 117, the washing liquid containing hydrogen peroxide can be supplied via the discharge line 121 to the lye container 105 for bleaching the laundry received in the washing drum 107 of the laundry care appliance 100.
Here, the supply of the washing liquid containing hydrogen peroxide into the lye container 105 can be controlled by means of the valve 123. If no washing liquid containing hydrogen peroxide is supplied to the lye container 105, the valve 123 is in the first position and the lye container 105 is fluidically separated from the substance container 117. If the valve 123 is pivoted into the second position, the substance container 117 is fluidically connected to the lye container 105 and the washing liquor containing hydrogen peroxide can be supplied from the substance container 117 to the lye container 105, and thus an effective bleaching of the laundry in the washing drum 107 can be achieved.
Thus, the supply of the washing liquid containing hydrogen peroxide, and thus the degree of bleaching of the laundry, can be regulated by the valve 123.
Fig. 3 shows a schematic view of a substance container which is fluidically connected to a water supply. In the lye container 105 of the laundry care appliance 100, a washing drum 107 is arranged for receiving laundry. The laundry care appliance 100 comprises a wash-in housing 101, wherein water is supplied from a water supply 109 to the wash-in housing 101 and wash liquor supplied by the wash-in housing 101 is supplied to the lye container 105 via a housing line 111. Furthermore, the laundry care appliance 100 has a discharge line 113, which discharge line 113 is connected to a lye pump 115, wherein the lye pump 115 is configured to: the washing liquid is pumped out of the laundry care appliance 100 through the discharge line 113.
Furthermore, the laundry care appliance 100 has a substance container 117, which substance container 117 is fluidically connected to a supply line 119 for supplying washing liquid into the substance container 117. The supply line 119 is connected to the water supply 109 of the laundry care appliance 100 for supplying water (in particular fresh water) from the water supply 109 to the substance container 117 via the supply line 119. The supply line 119 may have a further valve 133, the further valve 133 being configured to: the supply of water to the substance container 117 is controlled.
Furthermore, the substance container 117 is fluidically connected to the lye container 105 via a discharge line 121 for discharging the washing liquid from the substance container 117. The discharge line 121 has a valve 123, the valve 123 being configured to: in the first position, the lye container 105 is fluidically separated from the substance container 117, and in the second position, the substance container 117 is fluidically connected to the lye container 105. Thus, by the position of the valve 123 it is possible to control: whether washing liquid is supplied from the substance container 117 to the lye container 105.
A polyoxometallate catalyst 129 is received in the substance container 117 as explained with respect to fig. 2. In the case where the polyoxometalate catalyst 129 is contacted with the washing liquid, hydrogen peroxide is produced by a chemical reaction with water, whereby a washing liquid containing hydrogen peroxide is obtained. The supply of the washing liquid containing hydrogen peroxide into the lye container 105 can be controlled by means of the valve 123. If no washing liquid containing hydrogen peroxide is supplied to the lye container 105, the valve 123 is in the first position and the lye container 105 is fluidically separated from the substance container 117. If the valve 123 is pivoted into the second position, the substance container 117 is fluidically connected to the lye container 105 and the washing liquor containing hydrogen peroxide can be supplied to the lye container 105 and thus an effective bleaching of the laundry in the washing drum 107 can be achieved.
Fig. 4 shows a schematic view of a material container which is fluidically connected to the discharge line of the lye container. In the lye container 105 of the laundry care appliance 100, a washing drum 107 is arranged for receiving laundry. The laundry care appliance 100 comprises a wash-in housing 101, wherein water is supplied from a water supply 109 to the wash-in housing 101 and the resulting washing liquid is supplied to the lye container 105 via a housing line 111. Furthermore, the laundry care appliance 100 has a discharge line 113, which discharge line 113 is connected to a lye pump 115, wherein the lye pump 115 is configured to: the washing liquid is pumped out of the laundry care appliance 100 through the discharge line 113.
Furthermore, the laundry care appliance 100 has a substance container 117, which substance container 117 is fluidically connected to a supply line 119 for supplying washing liquid into the substance container 117. The supply line 119 is fluidically connected to the outlet line 113 (in particular the outlet container 135 of the outlet line 113). The washing liquid can thus be supplied from the discharge line 113 (or the discharge container 135) via the supply line 119 to the substance container 117. The substance container 117 is in particular designed as a washing liquid reservoir for receiving washing liquid. Furthermore, the substance container 117 is fluidically connected to the lye container 105 via a discharge line 121. The washing liquid can be pumped from the substance container 117 into the lye container 105 via the discharge line 121 by means of the liquid pump 137.
The discharge line 121 has a valve 123, the valve 123 being configured to: in the first position, the lye container 105 is fluidically separated from the substance container 117, and in the second position, the substance container 117 is fluidically connected to the lye container 105. Thus, by the position of the valve 123 it is possible to control: whether washing liquid is supplied from the substance container 117 to the lye container 105.
A polyoxometallate catalyst 129 is received in the substance container 117 as explained with reference to fig. 2 and 3. In the case where the polyoxometalate catalyst 129 is contacted with the washing liquid, hydrogen peroxide is produced by a chemical reaction with water, whereby a washing liquid containing hydrogen peroxide is obtained. The supply of the washing liquid containing hydrogen peroxide into the lye container 105 can be controlled by means of the valve 123. If no washing liquid containing hydrogen peroxide is supplied to the lye container 105, the valve 123 is in the first position and the lye container 105 is fluidically separated from the substance container 117. If the valve 123 is pivoted into the second position, the substance container 117 is fluidically connected to the lye container 105. Thereby, the washing liquid containing hydrogen peroxide can be supplied from the substance container 117 to the lye container 105, and thereby an effective bleaching of the laundry in the washing drum 107 can be achieved.
One of the many advantages of such a material container 117, along with the polyoxometalate catalyst 129 received therein, is that: without the addition of additives (e.g., detergents), a washing liquid (in particular a bleaching agent) containing hydrogen peroxide can be generated in the laundry care appliance 100. Thus enabling the laundry care appliance 100 to generate and add bleach in an automatically controlled manner. Thereby it is ensured that: depending on the specific laundry care situation (for example depending on the specific laundry care program), an optimally dosed amount of washing liquor (in particular bleaching agent) containing hydrogen peroxide can be used. This allows effective bleaching of the laundry without excessive dosing of the washing liquid containing hydrogen peroxide.
Furthermore, the polyoxometalate catalyst 129 is not consumed, so that the user of the laundry care appliance 100 does not have to purchase bleach, and there is always an effective bleaching action of the laundry care appliance 100 for use. Furthermore, no by-products harmful to the environment are produced and no unpleasant or possibly health-damaging odor is perceived by the user, which may occur, for example, when chlorine bleach is used. The continuous availability of such a washing liquid containing hydrogen peroxide, in particular a bleaching agent, can also be utilized in order to permanently keep the laundry care appliance 100 free of microorganisms and biofilm.
