The dust container is received in a chamber (11). The chamber is provided with an opening (16) through which the dust container can be removed from the chamber. The opening is normally closed by a cover (17). The cover (17) is provided with a heat-transmitting surface which is thermally connected to at least one heat-generating power component (42) disposed in the cover. ## Claims ### Claim 1 A vacuum cleaner comprising a housing (10) in which is disposed an electric circuit, a motor-fan unit (14), and a dust container (12), said dust container being received within a chamber (11) provided within the housing, the chamber being provided with an opening (16) through which the dust container is accessible, said opening normally being closed by a cover (17), wherein at least one heat generating power component (42) is disposed within said cover and the cover (17) includes a heat-transmitting surface (41) which is thermally connected to said at least one heat generating power component (42). ### Claim 2 (depends on 1) A vacuum cleaner according to claim 1, wherein the power component (42) is a triac. ### Claim 3 (depends on 1) A vacuum cleaner according to claim 1, wherein the power component (42) is a start-up resistor. ### Claim 4 (depends on 1) A vacuum cleaner according to claim 1, wherein the cover (17) includes an inner wall part (27) and an outer wall part (28), said wall parts being spaced a distance from each other and wherein an integrated circuit board with said power component (42) is disposed relatively between said wall parts. ### Claim 5 (depends on 4) A vacuum cleaner according to claim 4, wherein the cover includes a sleeve (18) to which a suction hose (20) is connected. ### Claim 6 (depends on 4) A vacuum cleaner according to claim 4, wherein the inner wall part (28) defines an air inlet opening (37), said air inlet opening communicating with a compartment (44), said compartment being at least partly limited by the heat-transmitting surface (41). ### Claim 7 (depends on 6) A vacuum cleaner according to claim 6, wherein the air inlet opening (37) is covered by a grating (38). ### Claim 8 (depends on 1) A vacuum cleaner according to claim 1, wherein said cover defines a compartment (44) which extends between said chamber and said heat-transmitting surface. ### Claim 9 (depends on 8) A vacuum cleaner according to claim 8, wherein said cover includes an inner wall part (28), said inner wall part defines an air inlet opening (37) for said compartment, said compartment being at least partly limited by the heat-transmitting surface (41). ### Claim 10 (depends on 9) A vacuum cleaner according to claim 9, wherein the air inlet opening (37) is covered by a grating (38). ### Claim 11 (depends on 9) A vacuum cleaner according to claim 9, wherein the cover (17) further includes an outer wall part (28), said inner and outer wall parts being spaced a distance from each other and an integrated circuit board with said power component (42) is disposed relatively between said wall parts. ### Claim 12 (depends on 11) A vacuum cleaner according to claim 11, wherein the air inlet opening (37) is covered by a grating (38). ### Claim 13 (depends on 12) A vacuum cleaner according to claim 12, wherein the cover includes a sleeve (18) to which a suction hose (20) is connected. ### Claim 14 (depends on 11) A vacuum cleaner according to claim 11, wherein the power component (42) is a triac. ### Claim 15 (depends on 11) A vacuum cleaner according to claim 11, wherein the power component (42) is a start-up resistor. ### Claim 16 (depends on 8) A vacuum cleaner according to claim 8, wherein the power component (42) is a triac. ### Claim 17 (depends on 8) A vacuum cleaner according to claim 8, wherein the power component (42) is a start-up resistor.
