Definitions

the invention relates to a tumble dryer with an air duct for guiding an air flow in the direction of a blower, wherein the air duct is formed with at least one curved portion formed in sections flow space in which the air flow undergoes a deflection in the direction of blower.
Such clothes dryers are e.g. known under the type designation Miele T 4462 C.
the tumble dryer is equipped in the area of the air ducts and the heat exchanger with sound absorbing agents, which significantly reduce the operating noise of the tumble dryer. In the area of the flow-deflecting channel sections of the air duct, however, further measures for noise reduction are required.
the invention thus raises the problem of implementing noise-reducing measures in a tumble dryer in the region of flow-deflecting channel sections with the least possible installation effort.
the advantages achievable with the invention consist in particular in that the velocity field of the air flow in the region of the deflection or in the curved flow space in front of the fan is made uniform by arranging a displacement body. By adjusting spiral-free flow of the impeller whirling are reduced resulting in a uniform flow distribution over the entire inflow. This uniform flow distribution causes a significant reduction in noise while increasing the volume flow.
the displacement body may also be expedient, according to a further advantageous embodiment of the invention, to arrange the displacement body on an axis running parallel to the blower axis.
the displacement body rotationally symmetrical.
the displacement body is spherical.
the displacement body is formed with a cylindrical and / or a conical portion.
the displacement body is particularly advantageous to shape the displacement body out of the wall section of the flow space or to form it as an integral part of the wall section of the flow space. According to a further embodiment, it is also possible to arrange the displacement body as a separate component in the flow space.
FIG. 1 a clothes dryer 1 with a rotatably mounted drum 2 is shown.
the feed opening 3 to the drum 2 is closed by a door, not shown here.
the feed opening 3 is encompassed by a functional component 4, which also contains the front air guide from the drum 2 in the direction of the blower 5.
the functional component 4 is formed in the region below the feed opening 3 as an air channel 6 (partially cut) for the air flow emerging from the drum 2.
the flow space 7 is visible in front of the blower 5 with the displacement body 8 arranged therein.
the flow space in which the air flow experiences a deflection in the direction of the blower 5 is curved in partial sections.
FIG. 2 the air duct 6 with the flow space 7 in front of the fan 5 with the displacement body 8 arranged therein is shown in section.
FIG. 3 The essential details of the invention are in FIG. 3 shown enlarged.
the displacement body 8 is positioned in the embodiment shown here on the impeller axis 9 and rotationally symmetrical.
the displacement body 8 has in the direction of the inflow surface 10 of the blower 5 a spherical portion 8 '.
the displacement body 8 is formed out of the wall portion 11 of the air channel 6 and the flow space 7 and integrally connected thereto. Depending on the geometry of the air duct 6, the displacement body 8 is formed in the region of the transition to the wall section 11 of the air duct 6 with an approximately cylindrical section 8 ", to which the spherical section 8 'connects.
the displacement body is formed with a conical portion.
the displacement body is formed as a separate component and fixed by means of a suitable connection technique (gluing, welding, notches, etc.) in the air duct.
the diameter d of the rotationally symmetrical section 8 "of the displacement body 8 is equal to or approximately equal to the nozzle diameter of the blower 5 denoted by c.
the coordination of the distance dimensions a and b to the geometry of the flow space 7 and to the nozzle diameter c of the blower 5 and the diameter d of the displacement body 8 causes a constant flow cross-section
the velocity field of the air flow can be adjusted via the parameters a and b.
the displacement body can also be positioned on an axis arranged at an inclination angle to the axis of the impeller axis.
