摘要：
Ein Haushaltsgerätefilter (3) weist zumindest teilflächig (6) mindestens eine vollkörperliche Filterlage (7) aus einem blockierreduzierten Filtermaterial (8) mit einer materialbezogenen Oberflächenenergie von 35 mN/m oder weniger auf. Ein Haushaltsgerät (2) weist mindestens ein Haushaltsgerätefilter (3) auf. Die Erfindung ist insbesondere vorteilhaft anwendbar auf Wäschepflegegeräte, speziell auf Wäschetrocknungsgeräte.
技术问题语段：
The technical problem addressed in this patent is the clogging of the filter layer of a household appliance with water during the cleaning process, which can lead to a decrease in the flow resistance of the process air and affect the operation and performance of the appliance. The invention proposes a solution by providing a filter with a surface energy of 35 mN/m or less, which prevents the filter openings from becoming blocked with water and maintaining a sufficient process air flow for a drying function.
技术功效语段：
The invention relates to a household appliance filter that can be used in devices such as laundry dryers. The filter has a layer with a low surface energy, which prevents water from blocking its openings and causing a flow resistance that affects the device's performance. The filter is easy to clean and can be made from a variety of materials such as metal or plastic. The invention aims to provide a cost-effective and efficient solution for preventing clogging of the filter's openings and ensuring optimal device performance.
权利要求：
1. A household appliance filter (3), which, over at least a partial surface (6), has at least one full-body filter layer (7) made from a blocking-reduced filter material (8) with a material-related surface energy of 35 mN/m or less, characterised in that the full body filter layer (7) has a layer manufactured in extruded form which has filter openings (9) introduced retrospectively.
2. Household appliance filter (3) according to claim 1, wherein the material-related surface energy of the blocking-reduced filter material (8) amounts to 30 mN/m or less, in particular 25 mN/m or less, in particular 20 mN/m or less.
3. Household appliance filter (3) according to one of the preceding claims, wherein the blocking-reduced filter material (8) has PTFE and/or PVDF.
4. Household appliance filter (3) according to one of the preceding claims, wherein over the whole surface a filter surface of the household appliance filter (3) has at least one filter layer (7) made from the blocking-reduced filter material (8).
5. Household appliance filter (3) according to one of claims 1 to 3, wherein only over a partial surface (6) a filter surface (5, 6) of the household appliance filter has at least one filter layer (7) made from the blocking-reduced filter material (8).
6. Household appliance (2) having at least one household appliance filter (3) according to one of the preceding claims.
7. Household appliance (2) according to claim 6, wherein the household appliance (2) is a laundry drying appliance and the household appliance filter (3) is arranged in a process air duct (1) of the laundry drying appliance.
8. Household appliance (2) according to claim 7, wherein the laundry drying appliance has a heat pump.
