8. Tumble dryer according to any of the proceeding claims, wherein the heat pump unit comprises a common frame (25, 26, 27).

9. Tumble dryer according to claim 8, wherein the condenser (19) the compressor (17), and the evaporator (15) are attached to the common frame (25, 27, 29).

10. Tumble dryer according to claim 9, wherein the condenser (19) is located above the compressor (17), and the evaporator (15) is located in front of the compressor as seen from the front side (3) of the tumble dryer.

1 1 . Tumble dryer according to claim 10, wherein the condenser (19) is supported by a top frame (25) of the common frame, the top frame supporting the condenser (19) at the edges of the condenser bottom surface (24), such that process air may pass through said bottom surface at inner parts thereof.

12. Tumble dryer according to claim 10 or 1 1 , wherein the evaporator extends into a space under the rotatable drum (1 1 ).

13. Tumble dryer according to any of the preceding claims, wherein the heat pump unit is provided with wheels (41 ), such that it can be rolled on a floor.

14. Tumble dryer according to claim 13, wherein the opening (31 ) has an inner floor (35) provided with slots (37) into which the wheels (41 ) may extend when the heat pump unit is installed in the tumble dryer.
