Water conducting household appliance
View Patent ↗A water conducting household appliance, particularly a dishwasher or a washing machine, having a hydraulic circuit, in which cleaning fluid can be recycled and in which at least one further filter is provided for filtering recycled washing liquor. In an exemplary embodiment, the appliance includes a filter in the hydraulic circuit for filtering recycled washing liquor. The filter may be disposed in a region of the hydraulic circuit in which the recycled washing liquor is rotated.
1. A water conducting household appliance, comprising:
a hydraulic circuit, in which washing fluid is circulated and at least one filter included in the hydraulic circuit and structured to filter circulated washing liquor; and
a circulation pump structured to generate the rotation of circulated washing liquor, wherein the circulation pump includes an impeller chamber with an impeller that conveys the washing liquor and a pressure chamber disposed downstream therefrom, and wherein the at least one filter is disposed in the pressure chamber and divides the pressure chamber into an inlet chamber, into which the washing liquor flows, and an outlet chamber, from which the washing liquor flows to an outlet-side pressure connection of the circulation pump, and wherein the inlet chamber of the pressure chamber is disposed radially outside the outlet chamber of the pressure chamber in relation to a center axis of the circulation pump.
2. The water conducting household appliance as claimed in claim 1 , wherein at least one of the inlet chamber and the outlet chamber extend in an annular manner about a center axis of the circulation pump.
3. The water conducting household appliance as claimed in claim 2 , further comprising a flow routing element connected between the impeller chamber and the pressure chamber.
4. The water conducting household appliance as claimed in claim 3 , wherein the flow routing element is structured to introduce the washing liquor tangentially along a housing wall of the circulation pump.
5. The water conducting household appliance as claimed in claim 4 , further comprising a pump sump connected upstream of the circulation pump, the pump sump including at least one of a coarse filter and fine filter disposed therein.
6. The water conducting household appliance as claimed in claim 5 , wherein the at least one of a coarse filter and a fine filter have a bigger mesh width than the at least one filter.
7. The water conducting household appliance as claimed in claim 6 , wherein the at least one filter includes at least one disk-shaped filter, which is positioned on a hollow cylindrical filter support, which divides the pressure chamber into the inlet and outlet chambers.
8. The water conducting household appliance as claimed in claim 7 , wherein the hollow cylindrical filter support extends coaxially to the circulation pump center axis between opposing boundary walls of the pressure chamber.
9. The water conducting household appliance as claimed in claim 8 , wherein the disk-shaped filter projects into the inlet chamber and at least one of the inlet and outlet chambers is bounded between at least one of the disk-shaped filter and the pump housing wall, extending in an annular manner about the center axis of the circulation pump.
10. The water conducting household appliance as claimed in claim 9 , wherein the disk-shaped filter is disposed at a radial distance from the pump housing wall in a radial direction outward by way of a flow gap.
11. The water conducting household appliance as claimed in claim 10 , further comprising at least one freely movable cleaning unit disposed in the pressure chamber.
12. The water conducting household appliance as claimed in claim 11 , further comprising a heating element structured to heat the washing liquor, wherein the heating element is disposed in the pressure chamber of the circulation pump.
13. The water conducting household appliance as claimed claim 12 , wherein the circulation pump is connected to the pump sump by a discharge line.
14. The water conducting household appliance as claimed in claim 13 , further comprising a blocking element disposed in the discharge line, which opens the discharge line when a washing liquor pump discharges the washing liquor from the pump sump.
