Domestic appliance for the care of washed articles
View Patent ↗A domestic appliance for the care of washed articles having with a container for receiving washed articles; a process air supply which is operationally connected to the container in fluid communication therewith whereby process air flows through the container during appliance operation; and a first heat exchanger which is in fluid communication with the process air supply for dehumidifying the process air exiting the container, the domestic appliance comprising a supplementary heat exchanger for lint filtering operationally disposed in the process air supply in fluid communication with the heat exchanger and the container.
1. A domestic appliance for the care of washed articles comprising:
a container for receiving washed articles;
a process air supply which is operationally connected to the container in fluid communication therewith whereby process air flows through the container during appliance operation;
a first heat exchanger in fluid communication with the process air supply for dehumidifying the process air exiting the container;
a second heat exchanger in fluid communication with the process air supply for heating the process air in the process air supply;
a heat pump with a working substance circuit whereby a working substance flows through the working substance circuit, wherein the first heat exchanger forms an evaporator of the heat pump, and the second heat exchanger forms a condenser of the heat pump; and
a supplementary heat exchanger for lint filtering operationally disposed in the process air supply in fluid communication with the first heat exchanger and the container,
wherein cooling elements of the working substance circuit lie against an outer side of the supplementary heat exchanger, and
wherein the supplementary heat exchanger is mechanically connected with a biasing element that presses the supplementary heat exchanger onto the cooling elements.
2. The domestic appliance according to claim 1 wherein the supplementary heat exchanger is disposed upstream of the first heat exchanger.
3. The domestic appliance according to claim 1 , wherein the supplementary heat exchanger functions as an additional evaporator and is operationally associated with the working substance circuit.
4. The domestic appliance according to claim 3 wherein the supplementary heat exchanger is connected in the working substance circuit in series with the evaporator.
5. The domestic appliance according to claim 1 , wherein the supplementary heat exchanger makes at least one of a positive and a non-positive fit with the cooling elements.
6. The domestic appliance according to claim 1 wherein a lint filter is arranged in the direction of the process air flow upstream of the supplementary heat exchanger.
7. The domestic appliance according to claim 1 wherein the supplementary heat exchanger can be removed without using a tool.
8. The domestic appliance according to claim 1 wherein the domestic appliance includes a tumble dryer.
9. The domestic appliance of claim 1 , wherein the biasing element is a spring.
10. The domestic appliance of claim 1 , wherein the biasing element is attached on one end to the supplementary heat exchanger and on another end to an inner wall of the process air supply.
11. The domestic appliance of claim 1 , wherein the supplementary heat exchanger has a second outer side that is opposite the outer side, and wherein the biasing element presses against the second outer side of the supplementary heat exchanger such that the outer side of the supplementary heat exchanger is pressed against the cooling elements.
12. The domestic appliance of claim 11 , wherein the biasing element is a spring attached on a first end to the second outer side of the supplementary heat exchanger and on a second end to an inner wall of the process air supply.
13. The domestic appliance of claim 1 , wherein a lint filter is arranged in the direction of the process air flow upstream of the supplementary heat exchanger, and
wherein the supplementary heat exchanger is disposed between the lint filter and the first heat exchanger for filtering lint from the process air before the process air flows over the first heat exchanger.
14. The domestic appliance of claim 1 , wherein the supplementary heat exchanger includes a plurality of plates stacked on each other and lying in a plane parallel to a direction of flow of the process air through the process air supply and having spaces therebetween, whereby the process air flows through the spaces.
15. The domestic appliance of claim 14 , wherein each of the plurality of plates includes one of a channel and a guide for guiding the process air and for capturing lint on a surface of the one of the channel and the guide.
16. The domestic appliance of claim 1 , wherein the cooling elements of the working substance circuit lie against the outer side of the supplementary heat exchanger without penetrating into the supplementary heat exchanger.
17. The domestic appliance of claim 1 , wherein the supplementary heat exchanger is removable from within and replaceable back into the process air supply for cleaning lint from surfaces of the supplementary heat exchanger.
