Cleaning device for a component loaded with lint in a household appliance, and method for cleaning a component loaded with lint
View Patent ↗A cleaning device for a component loaded with lint in a household appliance for laundry care. The cleaning device includes a rinsing unit to guide rinsing fluid to the component to remove the lint. The rinsing unit has a flow element disposed above the component, and the flow element builds up a dynamic pressure of the rinsing fluid in the flow element.
1. A cleaning device for a component loaded with lint in a household appliance for laundry care, the cleaning device comprising:
a rinsing unit to guide rinsing fluid to the component to remove the lint, the rinsing unit having a flow element disposed above the component, the flow element to build up a dynamic pressure of the rinsing fluid in the flow element,
wherein the flow element has an elongated part having a length, the elongated part having an opening for an egress of fluid on a side facing the component,
the flow element has a cross section that includes at least one narrow point to build up the dynamic pressure, and
the at least one narrow point extends over substantially the entire length of the elongated part of the flow element.
2. The cleaning device of claim 1 , wherein, at least before the at least one narrow point, the flow element has a first interior dimension that is larger than a second interior dimension at the narrow point.
3. The cleaning device of claim 1 , wherein the at least one narrow point has a symmetric cross section.
4. The cleaning device of claim 1 , wherein the at least one narrow point has an asymmetric cross section.
5. The cleaning device of claim 1 , wherein the opening in the elongated part of the flow element on the side facing the component extends over substantially the entire length of the elongated part.
6. The cleaning device of claim 1 , wherein the flow element has at least one element to at least one of position and hold the flow element on the component.
7. The cleaning device of claim 6 , wherein the at least one element is disposed on the elongated part of the flow element.
8. The cleaning device of claim 7 , wherein the at least one element and the elongated part of the flow element are a single piece.
9. The cleaning device of claim 6 , wherein the at least one element is disposed on a side of the elongated part of the flow element that faces the component and extends downward.
10. The cleaning device of claim 6 , wherein two elements are disposed on respective opposing ends of the elongated part of the flow element and extend downward and parallel to one another.
11. The cleaning device of claim 1 , wherein the flow element has a connector for a supply line for the rinsing fluid.
12. The cleaning device of claim 11 , wherein the connector is disposed on a side of the elongated part of the flow element that faces away from the component.
13. The cleaning device of claim 1 , wherein the component is a heat exchanger.
14. A cleaning device for a component loaded with lint in a household appliance for laundry care, the cleaning device comprising:
a rinsing unit to guide rinsing fluid to the component to remove the lint, the rinsing unit having a flow element disposed above the component, the flow element to build up a dynamic pressure of the rinsing fluid in the flow element,
wherein the flow element is configured as a single piece.
15. The cleaning device of claim 14 , wherein the single piece is a single-piece injection molded part.
16. A household appliance for laundry care, comprising:
a component loaded with lint; and
a rinsing unit to guide rinsing fluid to the component to remove the lint, the rinsing unit having a flow element disposed above the component, the flow element to build up a dynamic pressure of the rinsing fluid in the flow element,
wherein the flow element has an elongated part having a length, the elongated part having an opening for an egress of fluid on a side facing the component,
the flow element has a cross section that includes at least one narrow point to build up the dynamic pressure, and
the at least one narrow point extends over substantially the entire length of the elongated part of the flow element.
17. A method for cleaning a component loaded with lint in a household appliance for laundry care, the method comprising:
guiding rinsing fluid with a rinsing unit to the component for lint removal;
building up a dynamic pressure of the rinsing fluid in a flow element, the flow element having a cross section that includes at least one narrow point to build up the dynamic pressure,
wherein the flow element is assigned to the rinsing unit,
the flow element has an elongated part having a length, the elongated part having an opening for an egress of fluid on a side facing the component, and
the at least one narrow point extends over substantially the entire length of the elongated part of the flow element.
