Definitions
- the invention relates to a tumble dryer with the features of the preamble of claim 1.
- Comparable tumble dryers have been available on the market for many years.
- Rubber roller gears with friction rings used, which are essentially quiet and maintenance-free.
- the mentioned Rubber roller gears usually consist of two pairs of friction rings arranged opposite each other below the center plane of the dryer between them pick up the dryer drum in storage by moving it in the area of the Ends the dryer drum lengthways by raceways that define the bearing surfaces of the dryer drum form, unroll.
- a pair of friction rings is for the rotation of the drum connected to a drive in the form of an electric motor via a rotary shaft, the one via a gear unit and a chain drive around its nominal speed reduced drive speed to this rotary shaft with which the friction rings of the pair arranged at the ends are firmly connected.
- the axis of rotation over usual Ring bearing is rotatably mounted on parts of the housing of the dryer drum.
- the gear unit necessary for speed transmission or reduction along with Chain drive in the known drive units represents an essential cost factor in the manufacture of the dryer. It also happens over time wear of the chain drive, which with corresponding maintenance work and consequent downtimes of the tumble dryer. Since the rest of the known construction below the horizontal center plane of the dryer only the dryer drum is supported by the two pairs of friction rings, must be attached to the unloading side of the dryer drum Storage in the direction of the axis of rotation of the drum must be designed to be strong to be able to absorb additional forces. For additional storage forces To be able to effectively discharge into the dryer drum, it is also necessary to to design the sheet metal wall of the dryer more rigidly on the rear unloading side of the dryer and therefore increase the wall thickness. Also increase these measures the manufacturing cost of the dryer.
- the invention is based on the object to create a tumble dryer that is reliable in operation, inexpensive can be manufactured and is low-maintenance.
- a tumble dryer solves this task the features of claim 1.
- the electric motor is usually at the end and aligned with the Attack the drive shaft directly on it; but it is also possible to use the electric motor to be arranged in the center and the drive shaft at the end of each lead out.
- the latter solution is preferred, provided the electric motor is to be arranged in a space-saving manner within the housing of the dryer. Unless the drive shaft immediately - without the use of drive wheels - for driving the respective friction ring comes, this solution is particularly inexpensive and space-saving.
- Clothes dryer is at least part of the friction rings stored as friction wheels on a seesaw and under Action of an energy store against the one assigned to them Running ring started. Since the friction rings from one Rubber material exist, which is subject to wear and therefore reduces the diameter of the respective friction ring, is under the influence of the rocker Energy storage is given the possibility of the respective friction ring continuously via an infeed movement on the tread to keep the associated race, which in turn reduces the maintenance effort for the tumble dryer.
- Tumble dryers limit the drive shaft and the respective axis of rotation of the friction ring that can be driven by it with the drum axis of rotation relative to the vertical of less than 30 °. It has been shown that in one Arrangement in a particularly effective way occurring forces and moments of the dryer drum over the Drive shaft and the friction rings are supported. It has also proved to be particularly advantageous if the Drive shaft opposite the axis of rotation of each of them drivable friction ring is closer to the vertical plane, that passes through the drum axis of rotation.
- Tumble dryers are the friction rings in pairs on one fixed axis rotatably arranged parallel to the Drive shaft runs. Because of this arrangement, with structurally simple means an aligned position of the reach the respective friction ring pair.
- Tumble dryers are below the horizontal, in which is arranged the drum axis of rotation, two opposite one another Pairs of friction rings available, each over the fixed axis connected to each other in contact with the are at the end of the drum arranged races.
- two opposite one another Pairs of friction rings available each over the fixed axis connected to each other in contact with the are at the end of the drum arranged races.
- the tumble dryer shown in the figures has one by means of a drive device designated as a whole by 10 rotatable dryer drum 12.
- the dryer drum 12 is via rotatable friction rings 14 as part of friction wheels 16 in stored the housing 18 of the dryer.
- Passing friction rings 14 are sold under the brand name "ROTAFRIX" by distributed by Continental Aktiengesellschaft. Of the respective friction ring 14 is in contact with races 20, the are arranged at the end of the dryer drum 12 (see Fig. 2).
- the one seen in the direction of view on the right Side friction rings 14 are part of the drive device 10 in contact with a drive surface 22 by a drive in the form of an electric motor 24 in the direction of the arrow can be driven counterclockwise.
- the drive shaft shown 28 could, however, also drive wheels connected to it (not shown), which are in contact with the friction rings 14, the drive ratio for the rotation of the dryer drum 12 form.
- the addressed drive shaft 28 is via a Cross pin connection 30 at the end with the output shaft of Electric motor 24 connected and on the other hand in one Self-aligning ball bearings 32 guided.
- the electric motor 24 is over a motor flange 34 in the housing of the dryer as well as that Self-aligning ball bearings 32 supported.
- the drive shaft 22 also remains if the delivery movement is carried out in a permanent system with the Outer peripheral surface of the respective friction ring 14, so that it with the rocker 36 is therefore possible, even with a decreasing Diameter of the respective friction ring 14 or friction wheel 16 with wear a continuous system of the same to get the races 20 of the drum 12.
- FIG. 2 shows, the respective friction wheel 16 rotatable on one end via conventional deep groove ball bearings 52 fixed axis 54 arranged, which in turn on the end Bearing shells 56 fixed to the housing 18 of the dryer is.
- the term "fixed axis” means here that the axis 54 does not revolve, but in this respect is kept movable is when it moves over the rocker 36 in the direction of the outer circumference of the races 20.
- the pivot axis 46, the fixed axis 54 and the Drive shaft 28 are substantially parallel to each other arranged.
- the fixed axis 54 forms with its longitudinal axis hence also the axis of rotation for the one supported on it Friction wheel 16 with friction ring 14.
- the drum axis of rotation 60 divides the tumble dryer into one Vertical plane 62 and a center plane 64 (see Fig. 1). Connects the drum axis of rotation 60 with the fixed axis 54 over a fictional line 66 is that of this fictional line 66 preferably included with the vertical plane 62 less than 30 °. Furthermore, how this is particularly the Fig.1 shows, provided that the drive shaft 28 opposite the axis of rotation - here the fixed axis 54 - of her each driven friction ring 14 closer to the vertical plane 62 lies, which passes through the drum axis of rotation 60.
- the pair of friction wheels 16 can each have its own axis of rotation 68 for one Circulation in the direction of the arrow directly on the housing 18 of the dryer.
- the two axes of rotation 68 can but also connected part of another seesaw (not shown), which is an automatic feed movement of the respective friction wheel 16 to the races 20.
- this pair of friction wheels 16 can be compared to that on the right illustrated arrangement be formed and in particular have an independent drive (not shown), with which a kind of four-wheel drive for the dryer drum is achieved is.
- Fig.2 is seen from the center of the picture on the left Side the loading option given, whereas in the rear Unloading area for laundry items (not shown) consists of the dryer.
- this back Area is the dryer drum 12 via an axial and radial bearing 70 additionally supported in the usual way, the longitudinal axis of bearing 70 with the drum axis of rotation 60 coincides.
- This camp 70 in addition to the rear
- the area of the drum 12 can be dimensioned weaker because additional support is provided via the drive surface 22.
- the dryer has in its lower area as a whole with 72 designated fan between the two pairs of friction rings 14 on the underside of the dryer is arranged and the air transport in the usual way within the dryer is used.
- the drive shaft 128 is substantially vertical arranged and is below the fixed axis 154 preferably about 2 ° to 5 ° from this fictitious vertical plane arranged facing the viewer within the housing. If this is the case, the drive shaft takes over 128 with its drive surface 122 the only one Support of the dryer drum 112 in the area of the drive 124. Will be in a further embodiment of the dryer the addressed drive 124 also for that shown in FIG another pair of friction rings 114 used, a complete Support over the then available Drive shafts and their drive surfaces.
- the two are fixed Axes 154 on which the friction ring pairs 114 are rotatably arranged are, by means of fixed pressure rods 174 against the races 120 of the Dryer drum 112 turned on, at the back in Figure 3 illustrated pair of pressure rods 174 along the fictitious line 166 initiated forces in the opposite Acting in the direction supported on the dryer housing 118.
- the Force transmission along the foremost in Fig.3 arranged fictional lines 166 is comparable to the arrangement according to the Fig.1 again split into two directions, one Direction along the pressure rods 174 and the other Direction through the central connection of the fixed axis 154 to the drive shaft 128 is formed.
- the push rods 174 can be designed variable in length and therefore a Infeed movement of the respective friction ring pair 114 on the Allow treads 120 directed, so that a pertinent Adjustment movement also shows signs of wear the friction rings 114 can be compensated.
- the storage according to FIG. 3 via the friction ring pairs 114 allows essentially a radial support for the drum 112.
- Um also an axial support of the drum parallel to it
- the races 120 each have a flange on the end face (not shown), each between at least a pair of impellers (not shown) is guided with Parts of the housing 118 are firmly connected. Because of this arrangement is also a quiet circulation in the axial direction the dryer drum 112 guaranteed.
